Definitions

the invention relates to a bottle forming unit for forming bottles from bottle preforms.
the invention also relates to a transportable bottling plant.
the invention further relates to a method of forming bottles from bottle preforms.
Bottling plants in particular transportable bottling plants adapted for producing drinkwater bottles, are known from WO 201 1/095464 A1 and US 201 1/0302881.
the bottle blowing unit described in US 201 1/0302881 comprises a transporter arranged for moving carriers for carrying bottles or preforms along a semi-circular loop that has two corners.
the semi-circular loop described in US 201 1/0302881 is useful. However, the semicircular loop may be improved in view of an aim for efficient usage of space when a bottle forming unit is placed in a container.
WO 201 1/095464 discloses a transporter of a bottle forming unit arranged for consecutively moving carriers from carrier positions at corners of a rectangular loop, with time intervals between such consecutive movements.
standard 20-foot freight container a container compliant with the dimensional requirements for an ISO 668 standard 20-foot freight container.
the height of such a freight container is typically 8 or 8.6 feet.
heating water or potable water is meant water that is pure enough to be consumed or used with low risk of immediate or long term harm.
freshwater is meant naturally occurring water on the Earth's surface in ice sheets, ice caps, glaciers, bogs, ponds, lakes, rivers and streams, and underground as groundwater in aquifers and underground streams.
Fresh water is generally characterized by having low concentrations of dissolved salts and other total dissolved solids.
bottle is meant to include all kinds of hollow article suitable for use as a recipient, irrespective of its size and dimensions, in particular the relative proportions of a body part, provided for receiving a content, which may be any liquid or fluent product, and a neck part, delimiting an access opening for the filling, i.e. the placing of the content inside the body part, and typically also for the emptying, i.e. for extracting the content from the body part.
a content which may be any liquid or fluent product
neck part delimiting an access opening for the filling, i.e. the placing of the content inside the body part, and typically also for the emptying, i.e. for extracting the content from the body part.
the term “bottle” in a more narrow meaning is meant to include the recipients more commonly addressed as bottles, i.e. whereby the neck part is distinctly narrower than the body part, but also pots of which the neck part is hardly narrower than the body part.
bottle is meant to include any plant in which a bottle (as defined above) is produced from a preform and subsequently filled with a liquid or fluent product, including but not limited to water, sodas, wine, vegetable oils such as cooking oil, mineral oils such as motor oil, detergents, cleaning products, soft drinks, foods such as sauces, powders, such as milk powder, coffee powder, herbs or spices, chemical and pharmaceutical products, etc.
a liquid or fluent product including but not limited to water, sodas, wine, vegetable oils such as cooking oil, mineral oils such as motor oil, detergents, cleaning products, soft drinks, foods such as sauces, powders, such as milk powder, coffee powder, herbs or spices, chemical and pharmaceutical products, etc.
a bottle forming unit for forming bottles from bottle preforms, the bottle forming unit comprising a furnace for heating the bottle preforms and a moulder for moulding the heated preforms into bottles, the bottle forming unit further comprising a transporter for moving the bottles and/or the preforms, wherein the transporter comprises a plurality of movable carriers arranged for carrying the preforms and/or bottles, and comprises guiding elements for guiding the movable carriers, the guiding elements defining a loop of carrier positions where a carrier can be positioned, along which loop the carriers can be transported, the loop being provided for moving the carriers through the furnace and for moving the carriers from the furnace into the moulder, said loop having at least four corners, preferably at most four corners, at which a carrier position is provided, wherein the transporter comprises at least four advancers, an advancer being arranged for moving a carrier positioned at a corner away from that corner, wherein an amount of carriers and an amount of carrier positions are adjusted so that at least two
the transporter may be provided with a controller for controlling the advancers.
the controller may be arranged for simultaneously moving, by means of the advancers, carriers positioned at at least two diagonally opposed corners of the loop from those corners.
the controller may be arranged for moving a carrier away from one of the corners by means of an advancer simultaneously with moving another carrier away from another one of the corners by means of an advancer, said another one of the corners being arranged in the loop diagonally opposed to said one of the corners.
the loop has at least four corners, a freedom for choosing a shape of the loop may be improved compared to a known semicircular loop.
the loop may be arranged in a freight container more efficiently than the known semicircular loop.
simultaneously moving a first carrier and a second carrier may mean that at least part of the movement of the first carrier takes place at the same time as at least part of the movement of the second carrier, i.e. the movements at least partly overlap each other.
the term “simultaneously moving” may be interpreted more strictly. Then, at least 50%, preferably at least 80%, of a movement time of the first carrier takes place at the same time as movement of the second carrier.
a production rate of bottles can be increased by using two or more empty positions in the carrier system instead of one empty carrier position.
This makes it possible to advance, e.g. push, two rows of carriers simultaneously instead of advancing, e.g. pushing, one row of carriers consecutively.
the controller may be arranged for making two or more simultaneous translational movements of a row of carriers, instead of sequential translational movements of one single row of carriers after movement of another single row of carriers.
time needed for activating an advancer may be saved and an increased production rate may be achieved.
the controller may be arranged to operate the advancers so that two advancers located at diagonally opposed corner positions of the loop operate substantially simultaneously.
the two advancers by their operation may vacate carrier positions at at least two diagonally opposed corners.
the loop has the form of a rectangle.
the semi-circular loop of US 201 1/0302881 implies that the carriers may have to turn somewhat with every step in every pass along the curved part of the semi-circular loop. This may impose a limitation on a speed which the carriers may be given relative to their guiding elements, as well as on a minimum radius of the curved part of the semi-circular loop. This may represents a production rate limitation. Such limitation may become in particular relevant for relatively large bottles. Hence, the limitation may be more important for relatively large bottles having a volume of e.g. 5 liter, as compared to smaller bottles having a volume of e.g. 1 , 1 ,5 or 2 liter, as a carrier need to be larger for a larger bottle.
At least one part of the loop is substantially parallel to another part of the loop.
Such may e.g. be achieved in a loop that has the form of a rectangle.
the loop is closed in itself.
the loop is substantially horizontal.
the carriers are similarly shaped.
one and the same side of the carriers is movably connected to guiding elements.
the transporter comprises an advancer at each of the at least four corners of the loop.
each advancer is provided for advancing the carrier positioned at the corner over at least a single carrier position, e.g. a single carrier position or two carrier positions.
an advancer is provided for moving a carrier positioned at said corner away from that corner.
the amount of carriers and the amount of carrier positions are adjusted so that, in use, by advancing the carrier positioned at a corner away from that corner, a file of carriers abutting the carrier positioned at said corner is moved away from that corner and towards a next corner.
the amount of carriers and the amount of carrier positions are adjusted so that, in use, by advancing the carrier positioned at a corner of the at least four corners away from that corner, a file of carriers substantially abutting the carrier positioned at said corner is moved away from said corner towards a next corner located downstream of said corner.
a leading carrier of said file of carriers may optionally be positioned at said next corner.
the controller is arranged to advance the carrier positioned at the next corner after advancing the carrier positioned at the corner located upstream of said next corner.
the controller is arranged to operate the advancers so that the two advancers of each set of advancers positioned at diagonally opposed corner positions of the loop are operated substantially simultaneously.
a production rate of bottles may e.g. be further increased.
the two advancers of each set by their operation vacate carrier positions at at least two diagonally opposed corners, e.g. corners where the two advancers are positioned.
the carriers and preferably the carrier positions, have a first dimension and further have, measured in a direction transverse to the first dimension, a second dimension that is smaller than the first dimension.
the transporter is preferably arranged for transporting the carriers in a transportation direction through the furnace with the second dimension aligned with the transportation direction through the furnace.
the transporter is preferably arranged for transporting the carriers in a transportation direction through the moulder with the first dimension aligned with the transportation direction through the moulder.
an amount of carriers in the furnace per unit of length along the loop in the furnace may be larger than an amount of carriers in the moulder per unit of length along the loop on the side of the moulder.
an amount of preforms positioned in the furnace may be increased.
a more gradual heating of preforms in the furnace may be achieved.
the carriers may have similar dimension in a transportation directions of the carrier and transverse to a transportation direction of the carrier.
only one of the corners is provided along a part of the loop in between the furnace and the moulder.
heated preforms may enter the moulder relatively quickly after leaving the oven.
cooling of the heated preforms may be reduced.
the moulder is a blow-moulder, more preferably a blow-stretch moulder.
a blow-stretch moulder may combine well with a bottle forming unit. The stretching may diminish a size and/or weight of a driving unit needed for the blowing. A reduced weight and/or size of the transportable bottle blowing unit may be appreciated when transporting the transportable bottle blowing unit.
the moulder comprises a driving unit for driving the moulder, wherein the driving unit is positioned inside the loop.
the driving unit is positioned inside the loop.
the mould is provided with a plurality of mould parts.
the driving unit is arranged for opening and closing the mould by moving the mould parts with respect to each other.
the furnace may comprise a hot air exhaust conduit leading from the furnace towards the outside of the bottling room and provided with an induced draft fan for withdrawing hot air from a heating compartment of the furnace in which the preforms are heated.
the bottle forming unit may comprise a bottle marking device located adjacent to the transporter at a carrier position downstream of the moulder.
a bottle marking device located adjacent to the transporter at a carrier position downstream of the moulder.
An additional exhaust conduit may be provided leading from the carrier position at the bottle marking device, i.e. where the marking step occurs, to the hot air exhaust conduit, the additional exhaust conduit being provided for withdrawing fumes created upon marking the bottles by means of the bottle marking device, which may for example be a laser device.

bottling plants which may be tailored for supplying bottles filled with drinking water.
the bottling plants may be used for filling bottles with other liquid or fluent products, including but not limited to water, sodas, wine, vegetable oils such as cooking oil, mineral oils such as motor oil, detergents, cleaning products, soft drinks, foods such as sauces, powders, such as milk powder, coffee powder, herbs or spices, chemical and pharmaceutical products, etc.
liquid or fluent products including but not limited to water, sodas, wine, vegetable oils such as cooking oil, mineral oils such as motor oil, detergents, cleaning products, soft drinks, foods such as sauces, powders, such as milk powder, coffee powder, herbs or spices, chemical and pharmaceutical products, etc.
the principles described below are also applicable to such bottling plants.
the preferred embodiments are mainly described in the context of a standard 20-foot freight container. However, it is remarked that the principles described below are also applicable to transportable bottling plants in general, e.g. integrated into a 30-foot, 40-foot or other freight container, and many principles such as for example the furnace air supply, the bottle forming unit and the system for drying the wet circuit are even applicable to non-transportable bottling plants.
a transportable bottling plant which is incorporated into a 20-foot freight container 100, which is preferably a standard 20-foot freight container.
the internal volume of the container 100 is divided into separate rooms, one of which being a bottling room 107.
a preform feeder 1 18, a bottle forming unit 300 and a bottle filling and closing unit 1 19 are mounted in the bottling room 107.
the preform feeder 1 18 is provided for feeding preforms to the bottle forming unit 300.
the bottle forming unit 300 comprises a heater or furnace for heating the preforms and a moulder for moulding the preforms into bottles by making use of pressurized air.
the filling and closing unit 1 19 comprises a filling unit for filling the bottles with a liquid/fluent product and a closing unit for closing the bottles with caps.
An air compressor 1 13, an air conditioning unit 1 15 and possibly also a power generator 1 1 1 are mounted inside the internal volume but outside the bottling room 107.
the air compressor is provided for supplying pressurized air to at least the bottle forming unit 300.
the air conditioning unit 115 is provided for conditioning the air present in the bottling room 107.
the power generator 1 1 1 if present, is provided for generating electric power for the units of the transportable bottling plant, but is not essential - the units may also be powered by connection to e.g. an electricity network if this is available, in which case the power generator may be omitted.
a power socket (not shown) may be provided for example in the first technical room 108, to which all units are electrically connected.
the internal volume (separate from the bottling room) comprises at least a first 108, second 109 and third technical room 1 10, separated and sealed from each other.
the air conditioning unit 1 15 is mounted in the second technical room 109 and the air compressor 113 is mounted in the third technical room 110.
the freight container may be provided with personnel access 120 to the bottling room 107 separate from personnel access to the first technical room 108 and preferably also separate from personnel access to the second 109 and/or to the third technical room 1 10.
the first technical room 108 may be provided at one short side 102 of the freight container and the second technical room 109 may be provided at the opposite short side 101 of the freight container.
the first technical room 108, the second technical room 109 and the bottling room 1 10 may be separated from each other by separation walls 105, 106 which span the entire width and height of the freight container. These rooms are located one after the other in longitudinal direction of the freight container, with the technical rooms preferably at the short sides 101 , 102 of the freight container though this is not essential - all technical rooms 108, 109, 1 10 may also be arranged at the same short side of the freight container albeit with preferably separate accesses via the standard container doors and preferably other doors in the container sides 103, 104. As shown, e.g. the first 108 and third technical rooms 1 10 may be located above each other and may together take up substantially the entire width and height of the freight container. As shown, e.g. the second technical room 109, may alone take up substantially the entire width and height of the freight container.
personnel access 120 to the bottling room and hatches 121 , 122 for supplying the preforms, the bottle caps and the lock 123 for discharging filled bottles may be provided on the same side of the freight container, preferably a long side 103 of the freight container 100. It is customary that a tent is placed at the personnel access to the bottling room, to reduce the risk of dirt entering the bottling room when the plant is used in open air. An additional advantage can thus be obtained by locating all accesses for personnel to the bottling room on one side of the freight container, i.e. inside the same tent.
the power generator 1 1 1 and the bottle forming unit 300 may be mounted adjacent to each other on opposite sides of the first separation wall 105.
the power generator and the bottle forming unit 300 may be mounted in the freight container with at least one other unit of the bottling plant mounted between them, preferably the bottle forming unit 300 being located in a corner of the bottling room 107 which is opposite the part of the bottling room adjacent to the first technical room 108, where the power generator 1 1 1 is mounted, i.e. in a corner at the second separation wall 106. This can be achieved by switching the technical rooms in the floor plan of figure 4, as shown in figure 5.
the bottle forming unit 300 is further located in the corner of the bottling room 107 which is opposite the part of the bottling room wall closest to the internal combustion engine, which is typically the heavier part of the power generator 1 1 1 as compared to the electrical generator part.
the inventors have found that the bottle forming unit 300 and the combustion engine of the power generator are usually the heaviest pieces of equipment which need to be fitted into the freight container. By moving these two equipment items further apart, preferably as far apart as possible, the weight distribution of the freight container comprising the bottling plant is improved, which facilitates handling during transport and increases safety.
one or more windows may provided at the side of the container adjacent to the recipient 1 17 of the preform feeder 1 18 and/or a cap recipient 131 of a cap feeder 132, which feeds bottle caps to the filling and closing unit 1 19, and/or a handle recipient (not shown) of the filling and closing unit 1 19.
This hatch or hatches are provided for user supply of the "consumables", i.e. the plastic bottle preforms, bottle caps, bottle handles and/or labels, from outside the bottling room 107.
a lock 123 is preferably provided at the side of the container adjacent to the filling and closing unit 1 19, for passing filled and closed bottles towards the outside of the bottling room.
these hatches and lock are provided close to, and more preferably at the same side of, a door 120 through which the operator has access to the bottling room, for intervention such as in case of emergency.
these access facilities, hatches and lock are provided at one of the longer sides of the freight container, such that a shelter or tent may be provided at that side, preferably over the total length thereof, for providing protection for the operator as well as any storage of consumables and/or filled bottles.
Such shelter may also reduce the risk of contamination of the bottle room when the access or any hatch needs to be opened.
the inventors prefer to arrange the equipment in the container 100 such that the technical rooms 108-1 10 are located at the shorter sides of the freight container, with full fledged doors on both sides such that full access is provided for servicing the equipment mounted in those technical rooms, but also for assembly of the bottling plant ancillary equipment, and/or for disassembly and possible replacement of a particular equipment items which became faulty.
an access door 120 may readily be located in one of the longer sides 103 of the freight container at a location from where all equipment items in the bottling room may be easily accessible and even serviceable with a minimum of space which needs to be reserved inside the bottling room 107.
level 1 has the lowest and level 5 the highest hygiene requirements and each level may mean a separate room/compartment in the container:
Level 3 product treatment, buffering and/or processing facilities (e.g. freshwater polishing or purification, ... ) 1 16, centralised product (e.g. freshwater) feeding and discharging system 129;
buffering and/or processing facilities e.g. freshwater polishing or purification, ...
centralised product e.g. freshwater
the chiller is provided for cooling a chilling agent which may be supplied to the mould parts and the perform necks in the oven, for cooling these parts during use.
the freight container 100 may be provided with personnel access to the bottling room 107 separate from personnel access to the first technical room 108 and preferably also separate from personnel access to the second 109 and/or to the third technical room 1 10.
This access arrangement further improves the separation of the activities in the technical rooms with those in the bottling room, and thus further facilitates the maintenance of the desired high hygienic standards in the bottling room.
the first technical room 108 may be provided at one short side 102 of the freight container, the second technical room 109 preferably being provided at the opposite short side 101 of the freight container.
the inventors have found that this is a very convenient layout, convenient not only for assembling the bottling plant, but also for servicing the equipment in the various technical rooms or spaces of the freight container.
the power generator 1 1 1 comprises an internal combustion engine which is provided with direct or indirect air cooling, whereby the hot air outlet of the air cooling is provided in the freight container wall, preferably the air intake of the engine air cooling being provided inside the first technical room 108.
the inventors have found that it is even more desirable to mount a power generator which is driven by an internal combustion engine in a technical room separate from the space containing the air compressor and the space containing the air conditioning unit. Both the latter pieces of equipment would be sensitive to any exhaust gasses leaking from the internal combustion engine and/or any lubricating oil particles or aerosols which may be emitted by the engine. Also the heat from the power generator may affect the air compressor and the air conditioning system.
the bottling plant may further contain a fuel tank 125, whereby the inventors prefer to mount the fuel tank in the first technical room 108 or in a fourth technical room provided as part of the freight container 100, preferably in the first technical room, and even more preferably underneath the basis supporting the power generator 1 11.
the fuel tank 125 for the internal combustion engine of the power generator 1 1 1 may be preferably provided underneath a forklift compatible base and preferably attached thereto, for easy removal from the first technical room.
this location of the tank is the best place as part of the freight container for mounting the fuel tank, providing the least risk for contamination of the sensitive parts of the bottling plant and its ancillary equipment with any fumes or aerosols from the fuel, such as during filling the fuel tank.
the bottling plant according to the present invention may further comprise a water treatment unit 116 which is preferably mounted in a space different from the first technical room 108, preferably the water treatment unit being mounted in the second technical room 109.
a water treatment unit provides the capability to use a broader range of fresh water sources as raw material to the bottling plant.
the inventors prefer to mount this water treatment plant in the second technical room 109, as its presence does not jeopardize the operation thereof, nor does the air conditioning unit 1 15 possibly jeopardize the operation of the water treatment unit.
the bottling plant further comprises means for maintaining a pressure in the bottling room which is above the pressure of the atmosphere surrounding the freight container, preferably at least 0.5 mm H20 and optionally at most 3.5 mm H20 above the surrounding atmosphere (i.e. about 5 Pa to about 35 Pa overpressure or gauge).
the overpressure brings the advantage that the risk for contamination of the bottling room from the outside is strongly reduced, and that compliance with the international regulation on hygiene may be more readily maintained.
the means for maintaining the pressure in the bottling room is at least partially provided by the air conditioning unit 1 15, preferably the air conditioning unit being provided with a first air intake for recycling air from the bottling room 107 and a second air intake from outside the bottling room 107 for bringing in fresh air, preferably from inside the second technical room 109.
the air conditioning unit is mounted in a technical room separate from the power generator, and any fresh air intake by the air conditioning unit may readily occur in the second technical room itself.
the air coming into the second technical room may readily be filtered on its way into the second technical room, with a large area filter which brings only a negligible pressure drop.
the filling and closing unit 1 19 comprises product inlet and outlet piping connected to product inlet and outlet connectors which are provided in one of the sides of the container, in particular in a centralised product infeed and discharge system behind hatch 129 in the container wall part of the second technical room 109, so that they are accessible from outside the bottling room.
the product inlet connector may be provided for feeding the product with which the bottles are to be filled.
the product inlet and outlet connectors together may also be used to create a closed loop for a cleaning product (clean-in- place system). So by means of the product inlet and outlet connectors accessible from outside the bottling room, both the product supply during operation and the supply and discharge of cleaning product during cleaning may be effected from outside the bottling room.
the filling and closing unit 1 19 comprises a system for treatment of the product with chemicals before filling the bottles, the product treatment system optionally comprising a chemicals supply piping connected to a chemicals inlet connection provided in one of the sides of the container, for example behind the same hatch 129, so that it is accessible from outside the bottling room. So by means of the chemicals inlet connection accessible from outside the bottling room, the supply of chemicals for the treatment of the product in the product treatment system may be effected from outside the bottling room. This brings the advantage that hygiene may be enhanced, as the risk of contamination by operators entering the bottling room is minimised in view of the fact that there is no need for an operator to enter the bottling room for the supply of the chemicals for the product treatment.
the bottle forming unit 300 may be provided with a cooling circuit for circulating a cooling liquid through parts of the bottle forming unit, in particular at least one and preferably both halves of the bottle mould.
a cold source or a chilling device for cooling the cooling liquid may be located in the second technical room 109..
the present invention may operate with any suitable thermoplastic for moulding bottles.
suitable thermoplastics is too long to enumerate, but the more appropriate thermoplastics are also the more common ones, such as polyvinyl chloride, polyethylene, polypropylene, and polyesters, in particular polyethylene terephthalate (PET), which is preferred.
PET polyethylene terephthalate
the person skilled in the art may readily adapt the bottling plant to the thermoplastic which is selected, such as adapting the desired preheat temperature range to for instance the glass transition temperature of the selected material.
the bottling plant can also be adapted for operation with preforms in biodegradable materials, such as polylactic acid (PLA) or other.
PLA polylactic acid
a container 100 in particular a standard ISO 20 ft container.
the plant is adapted for being quickly transported to a place of need, which can for example be a place struck by a calamity, a remote place where military operations take place (e.g. desert), a stationary bottling plant which has insufficient capacity to meet the demand, or other.
the container 100 has a front side 101 opposite a back side 102, which form the shorter sides of the container, and two opposite lateral sides 103 and 104, which form the longer sides of the container.
the container 100 has separation walls 105 and 106 which divide the interior of the container into a bottling room 107, and at least a first technical room 108, a second technical room 109 and a third technical room 1 10.
the bottling room 107 contains all the electrically powered units for manufacturing closed and filled drinking water bottles starting from a supply of consumables, in particular plastic bottle preforms, bottle caps, possibly bottle carrying handles and labels, and a supply of drinking water.
the first technical room 108 shown in figure 1 , contains the electric power generator 1 1 1 for generating the power to be consumed by most of the other equipment items of the bottling plant and ancillaries.
first technical room may be provided an extra separate compartment, representing the third technical room 1 10, separated from the first technical room by means of an extra floor 112.
This floor may then be provided with seals such that the third technical room is sealed from the first technical room when the doors of freight container are closed.
the first and the third technical rooms may be provided with individual air intakes, preferably provided with respective air filters, see e.g. filter 126 in the side wall of the container, or filters through the container doors (not shown).
Waste heat from the power generator may be pushed out of the first technical room, preferably also out of the freight container via grid 127 in the side wall of the container, by means of a cooling fan, optionally through a "radiator" in which a liquid for cooling the internal combustion engine of the power generator is relieved of its excessive heat before being returned to the engine.
This fan provides extra draught in the first technical room, possibly in addition to the draught which may be provided by the air intake of the internal combustion engine, if this engine takes its combustion air from the first technical room itself. This brings the advantage that the air for the combustion is already filtered a first time when entering the first technical room, so that the combustion air filter of the engine itself may be provided simpler and smaller and/or that the operating reliability of the engine is improved, in particular in highly dusty environments.
the third technical room 110 contains air compressor 113 for supplying pressurised air, which compressor preferably is a two-stage three cylinder reciprocating compressor.
the third technical room may further comprise the compressed air dryer 114 for cooling the air from the compressor, in case of a multistage air compressor the cooler may comprise an intercooler for cooling the air from the first compressor stage, separating any condensed water from it, and returning it to the second compressor stage.
the air from the last compressor stage is preferably also cooled before further treatment and storage. This brings the advantage that extra humidity may be condensed and separated off, such that it becomes easier in a later stage to achieve the desired low dew point required for complying with the regulations of compressed air for the production of food and stimulants. Separating off condensed water is preferably performed by means of an electronically level-controlled condensed removal apparatus ("ECO-Drain").
ECO-Drain electronically level-controlled condensed removal apparatus
Further treatment of the compressed air may comprise at least one and preferably all, of one or more pre-filtration, fine filtration, microfiltration and after-filtration steps for separating solid particles and aerosols including oil-aerosols of various sizes at appropriate places in the process, a step for the reduction of the dew point of the air to 4°C or below, preferably by means of a refrigerated dryer, an activated carbon adsorption step for further scavenging undesired components, such as oil vapours, and these steps not necessarily being in this sequence.
the compressed air dryer 114 may be provided with a fan pushing the hot environment air from the cooler through a grid in the outer wall of the technical room, preferably also the wall of the freight container, and provide for additional air draught in the technical room.
the second technical room 109 contains the air conditioning system 1 15 for conditioning/cooling the air in the bottling room 107. It has, in the embodiment of figure 3, a fresh air intake through filter 128 in the side wall of the container and an air discharge 130 through the ceiling of the container.
the inventors have found that it is very important that the atmospheric conditions in the bottling room remain relatively constant.
the bottle forming step is very sensitive to being fed preforms of which the bodies are heated uniformly and at a temperature in the correct range. When excessive temperature deviations occur in the preform at the moment of forming the bottle, the process may fail in many aspects.
the plastic of the bottle may loose its transparency, and an opaque bottle may be formed.
the bottle may have mechanical weak spots, show cracks or even burst.
the neck of the bottle should not be exposed to the same temperature, but preferably remains shielded and cool during the preheating step. This is because when heated it may deform such that the bottle cap does not fit anymore and the bottle cannot be sealed properly, such that the hygienic quality of its content cannot be maintained.
the inventors have found therefore that a correct sizing and a correct functioning of the air conditioning unit 1 15 is important for a flawless operation of the bottling plant.
the inventors have also found that it is desirable to avoid as much as possible external influences which may affect the conditions in the bottling room.
the influences to be avoided as much as possible include influences with a continued effect, but even more important influences which are temporary and unpredicted, because these are more difficult to cope with by the air conditioning unit.
the front side 101 and back side 102 of the container are preferably provided with conventional container doors (not shown) by means of which the two or more technical room may be closed off for the purposes of transportation.
the air compressor 1 13 may for example be provided for supplying pressurised air within a range of for example 15-25 bar
the bottling plant of figure 1 can for example be used for making 1 , 1.5 or 2 litre bottles, or any volume from 0,25 up to 5 litre or even larger.
a handle applicator is usually not used for the smaller bottles because the smaller bottles typically do not need to be provided with a handle.
the bottling plant can be made suitable for operation in relatively extreme atmospheric conditions (e.g. 55°C and 85% humidity).
relatively extreme atmospheric conditions e.g. 55°C and 85% humidity.
the more efficient use of space and the provision of the separate technical rooms provide sufficient space for ancillary equipment of sufficient power.
the separation wall 105 between the first technical room, optionally including the third technical room, and the rest of the freight container may provide both a thermal and an acoustic isolation, such as between the bottling room 107 and the technical room 108.
the wall preferably comprises a rockwool plate of 80 or 100 mm, such as for example the "Marine Slab 55" available from manufacturer Rockwool Technical Insulation NV. The inventors have found that this insulates the "hot" ancillary equipment, i.e. the internal combustion engine and the air compressor, from the bottling room 107. By the extra thermal insulation, the duty requirements for the air conditioning unit may be reduced, its operation becomes more reliable, and its power consumption can be reduced.
the wall or floor 1 12 separating the first and the third technical rooms does not need to be insulated for sound nor for heat transfer, as both technical rooms contain "hot" equipment.
the separation wall 106 between the second technical room 109 and the bottling room 107 does not need the same insulation thickness.
the second technical room 109 does not contain "hot" ancillary equipment, nor equipment which is very noisy.
a minimum of thermal insulation, similar to what is foreseen in the other walls of the bottling room excluding separation wall 105 is sufficient. This brings an extra improvement of space utilization.
the air conditioning system of the bottling plant of the present invention may be of the split type having a separate condenser unit 115 in the second technical room and an evaporator unit (not shown) inside the bottling room 107.
the air conditioning system could also be a unitary system, mounted in the same compartment of the second technical room as the condenser unit 1 15 with then a grid towards the bottling room 107.
the inventors have found, by bringing the cool air outlet of the air conditioning unit close to the bottle forming unit 300, that it is easier to accurately control the temperatures of the preforms, including the neck but evenly important the temperatures of the different zones of the preform body, and that the operating reliability of the bottle forming unit is thereby significantly improved. This brings an important contribution to an improved operating reliability of the overall bottling plant.
the following units are provided in the bottling room 107: a preform feeder 1 18 for feeding and orienting the plastic bottle preforms, a first transferring device 141 , a bottle forming unit 300 for forming plastic bottles from the preforms and a filling and closing unit 1 19.
the units may be organised around one large closed loop transporting unit, such as described in WO 201 1/095464 A1 , which may be arranged in a double file as shown or in a single file along the loop, which reduces the footprint of the bottling plant.
the filling and closing unit 1 19 is a separate unit from the bottle forming unit 300, so that it is at all times avoided that any product comes into contact and could contaminate the carriers of the bottle forming unit and hygiene can be improved.
the filling and closing unit 1 19 can for instance use a carousel for passing the bottles from one position up to the next.
the bottle forming unit and its preheat unit may then operate around a smaller closed loop transporting unit, such as for instance described in US 201 1/0302881 A1. This separation of the two operational steps may also provide more freedom in the layout of the equipment to be arranged in the bottling room.
a second transferring device 142 is provided for removing the formed bottles from the bottle forming unit 300 and for feeding these to the filling and closing unit 1 19.
these units provide a unit for every step in the bottling process, so that the bottling plant is able to run substantially without manual intervention. This also contributes to hygiene as no continuous presence of an operator in the bottling room is required. In the following, the units will be described in more detail.
the preform feeder 1 18 is similar to the one described in US 201 1/0302881 A1 or WO 201 1/095464, and comprises a recipient 1 17 for receiving and buffering plastic bottle preforms.
the recipient 1 17 may be accessible via a first hatch 121 provided in the side wall 103 of the container.
This first hatch 121 preferably has a door which pivots around its bottom side, and by opening ends up in a slanted position so that it may form a slide towards the recipient.
the operator may readily throw in preforms from outside the bottling room 107. By emptying onto the slide boxes of preforms which have remained sealed until just before, high hygienic standards may be maintained with respect to the cleanliness of the fed preforms.
the preforms present in the recipient may then be picked up by a conveyor belt and fed to an ordering unit.
the ordering unit may then arrange the preforms with their neck pointing upwards onto a slide/hopper, on which the preforms are transported towards the bottle forming unit 300.
the first transferring device 141 may preferably comprise a 180° rotatable arm with a gripping mechanism, by means of which the preforms are picked up one by one at their neck and placed upside down, i.e. with their neck pointing downwards onto preform/bottle holders or "carriers" of the bottle forming unit 300.
Turning the preforms upside down at this stage has the advantage that any dirt present in the preforms would be allowed to drop out.
the preforms may be dropped into position on a carrier, such as described in WO 2044/095464, but the drawback of such arrangement is that any strange object inside the preform is unable to drop out, and will remain in the preform and in the bottle which is formed therefrom.
the preform/bottle holders may also be called the “carriers”. Typically about at their centre point, they comprise a mandrel, herein also called “holders 324" upon which the preform is placed by the first transferring device 141.
the mandrel may be provided with an insert entering the preform neck, through which later the heated preform may be stretched and the bottle may be formed by blowing. Because of the pressure involved in the blowing, a seal may preferably be provided between the preform neck and the mandrel insert, typically a rubber seal, preferably a rubber o-ring.
the inventors have found that it may be difficult to have the first transferring device 141 , when it places the preforms onto the mandrel insert, also assure that the preform is pushed down sufficiently far over the mandrel insert in order to assure a good seal between the neck and the mandrel insert.
the inventors therefore prefer to add an additional step, whereby the preform, after it has been placed on the mandrel over the mandrel insert, is pushed down further over the mandrel insert such that the seal is assured.
bottle forming unit 300 one suitable embodiment is already shown in detail in figure 4 of US 2011/0302881 A1 , which comprises an array of preform/bottle holders which are coupled in a semi-circular chain.
the inventors have found that an improved space utilization may be obtained with the bottle forming unit 300 as shown in enclosed figure 7 comprising an array of preform/bottle holders which are coupled in a rectangular chain.
the preform/bottle holders are preferably pushed stepwise from one position to the next by pushing apparatuses appropriately located around the chain or carriers, and guided by guiding elements which define the path of the chain.
the semi-circular chain of US 201 1/0302881 A1 may need not more than two advancers, one pushing the carriers along the straight part of the semi-circle, the second one pushing the carriers along the semi-circular part of the chain.
the rectangular chain shown in enclosed figure 7 may need at least 4 advancers, one located at each corner for pushing the carriers into and further along the side downstream of the corner.
the rectangular transporter 302 of the preferred embodiment of the bottle forming unit 300 shown in figure 7 will be described further below in more detail.
the preforms When placed on their carrier as part of the chain, and after pushing the preforms well over the mandrel inserts to assure they are correctly in position and well sealing around the mandrel inserts, the preforms are moved into heater 205 for heating up the preforms to the extent that the material of the bodies of the preforms becomes mouldable.
the heating may be performed with any suitable type of heating elements. Suitable are for instance the electrically driven heating rods described in WO 2011/095464. With such heating rods, most of the heat transfer to the preforms occurs by convection.
the inventors however have found that the heat transfer by convection is more difficult to control and maintains a significant risk for non-uniform heating of the preforms.
the inventors prefer to use a radiation heated oven or furnace for heating the preforms, e.g. by means of heating lamps.
This means of heating allows a better control of the heat distribution over the various zones of the preform body, which should be heated as uniformly as possible with the temperatures all in a prescribed range, a range which depends on the thermoplastic which is selected for the preform.
the inventors have found that it is also easier to shield the preform necks from radiation heat, without requiring extra cooling of the necks in order to keep them below the desired temperature so that the risk for problems during the forming step, or downstream, may be minimised.
the inventors prefer to monitor and control the preform heating in multiple zones, in order to achieve the desired uniform heating.
These lamps may be longitudinal in shape and may be arranged on one side or on both sides of the preforms moving through the radiation furnace, parallel to the direction of movement, stacked vertically one above the other. Each lamp heats one heating zone, and the heating zones are thus preferably arranged vertically one above the other.
the inventors prefer to control the power fed to the individual lamps, preferably to the lamp heating one particular zone in accordance with the temperature measured on the preform body part inside that zone. This temperature measurement is preferably done by Infrared (IR) temperature measurement.
IR Infrared
the mandrels are preferably provided rotatable relative to the carriers which support them, and are more preferably rotated such that also the preforms rotate around a vertical axis during their path through the radiation furnace.
the rotation of the preforms may be provided by any suitable means, but the inventors prefer to have mandrels provided with a gearwheel, similar to what is shown in Fig. 4 of WO 201 1/095464 A1 , the teeth of which grip into a chain or into other suitable element for receiving the teeth.
the chain or other suitable element may be provided stationary inside the heating furnace, or may if desired be made to move in order to provide continuous rotation of the preform during the preheat, and to provide further control over the speed at which the preforms are rotating during their path through the furnace.
the preforms With a stationary element receiving the teeth of the gearwheel, the preforms rotate in steps, with intermittent periods without rotation. This increases the risk for non-uniform heated preforms and hence a risk for faulty bottles and bottling plant malfunction.
the inventors prefer to have the preforms move continuously, and preferably at a sufficiently high rate such that the effects of the stepwise movement of the carriers through the furnace is reduced and preferably becomes negligible.
the inventors prefer to keep the preform necks significantly cooler than the bodies.
the prime purpose of this is to avoid deformation of the neck during the bottle forming step, and malfunctioning of the downstream equipment.
the inventors have found that with radiation heating it is easier to keep the preform necks cool, typically simply by properly placed heat shields. This is even simpler and easier with appropriate control of the air flow through the heating furnace and also with the preforms turned upside down.
the heater is preferably located at one straight part of the rectangular chain of transporter 302, typically along one of the longer sides of the rectangle. With radiation heating, the inventors prefer to use heating lamps of standard size.
the second transferring device 142 preferably comprises a 180° rotatable arm with a gripping mechanism, by means of which the bottles are picked up from the carriers one by one at their neck, turned over and placed upright, i.e. with their neck pointing upwards, if desired onto a transporter device 124 which passes through the filling and closing unit 1 19 up to lock 123.
the filling of the bottle is preferably performed in two steps: a prefilling step in which 70-80% of the bottle is filled, followed by a second finishing filling step, wherein the remaining 20-30% is filled and the bottle is filled to the desired height and/or volume.
the two-step filling reduces the risk of overflow during the filling, and hence allows better housekeeping and thus also higher hygienic standards in the bottling room. It also reduces the need for operator intervention for cleaning up spilled liquid from the bottling room.
the filling and closing unit 1 19 preferably comprises a glass housing in which UV lamps (not shown) are provided for treatment of the drinking water, air, caps and bottles, and in which the filling operation takes place and the caps are screwed onto the bottles.
UV treatment and the filling and closing operation are known from stationary bottling plants and therefore need no further description here.
the filling and closing unit 119 has a cap feeder 132 which feeds the caps from a cap recipient 131 into the closed filling and capping unit 1 19.
the cap recipient is accessible via a second hatch 122 in the side 103 of the container, so that no operator is required to enter the bottling room in order to supply caps to the cap recipient 131.
the filling and closing unit 1 19 may further have a handle recipient for feeding bottle carrying handles to a handle applicator (not shown).
the filled and closed bottles exiting the closed filling and capping unit 1 19 on the transporter device 124 then may pass a labeller (not shown) for applying a label to the bottle and optionally also printing a code identifying lot number and date onto the bottle.
the finished bottles may be transferred from the transporter device 124 inside the bottling room through lock 123 in the side of the container, towards an accumulation device (not shown) outside the bottling container for further handling operations.
the bottle forming unit 300 is mounted in the bottling room 107 of the bottling plant 100.
the bottle forming unit comprises a furnace 204 for heating the thermoplastic bottle preforms in a heating compartment 205, a bottle former (herein also called “moulder") for forming the heated preforms into bottles and transporting means for transporting the bottle preforms fed to the transporting means by the preform feeder 1 18 through the heating compartment 205 and into the bottle former and further transporting the formed bottles to the bottle filling and closing unit 1 19 and/or a second transferring device 142 for transferring the bottles to a separate bottle filling and closing unit 1 19.
a bottle former herein also called “moulder”
transporting means for transporting the bottle preforms fed to the transporting means by the preform feeder 1 18 through the heating compartment 205 and into the bottle former and further transporting the formed bottles to the bottle filling and closing unit 1 19 and/or a second transferring device 142 for transferring the bottles to a separate bottle filling and closing unit
the furnace 204 preferably comprises a fresh air inlet conduit 206 leading from the outside of the bottling room 201 to the heating compartment 205 for leading fresh air from the outside of the bottling room 201 to the heating compartment 205.
the fresh air inlet conduit preferably opens to an inlet behind a hatch 219 (see figure 3).
the fresh air inlet conduit 206 leads from the outside of the freight container 100 to the furnace 204, more in particular to the heating compartment 205, for leading fresh air from the outside of the freight container 213 to the furnace 204, more in particular the heating compartment 205.
the fresh air conduit 206 could also lead from for example one of the technical rooms 108-1 10, this is less desirable as in such configuration there is an increased risk that undesired substances enter the heating compartment.
the bottling plant 100 further comprises a filter 210 for filtering the fresh air taken in through the fresh air inlet conduit 206.
a filter 210 for filtering the fresh air taken in through the fresh air inlet conduit 206.
the filter 210 is not critical and may be omitted.
the preferred type of the filter 210 may depend on, for example, the environment wherein the freight container is positioned and/or the nature of the air which is conducted through the inlet conduit 206.
a forced draft fan 208 is provided.
the forced draft fan 208 may be omitted, in which case the fresh air enters the heating compartment 205 through the inlet conduit 206 by, for example, diffusion, the forced draft fan 208 preferably is provided to improve or to control the provision of fresh air to the heating compartment 205.
the furnace 204 also comprises a hot air exhaust conduit 207 leading from the furnace 204 towards the outside of the bottling room 201 , so for leading hot air from the furnace 204 to outside the bottling room 201.
a hot air exhaust conduit 207 leading from the furnace 204, more in particular from the heating compartment 205, to the outside of the freight container 100, preferably through an outlet behind a hatch 220 in the side wall 104. This is however not critical for the invention and the hot air exhaust conduit 207 may also lead from the furnace 204, more in particular from the heating compartment 205, to one of the technical rooms 108-1 10 of the freight container.
the furnace preferably comprises an induced draft fan 209 for withdrawing hot air from the heating compartment 205.
the induced draft fan 209 may be omitted, in which case the hot air leaves the heating compartment 205 through the exhaust conduit 207 by, for example, diffusion or convection
the induced draft fan 209 preferably is provided to improve or to control the withdrawal of hot air from the heating compartment 205, especially when the induced draft fan 209 and the forced draft fan 208 are provided together.
the fresh air inlet conduit 206 may be provided with a pressure relief valve 212 for relieving any excessive fresh air from the conduit towards an outlet 218 towards the bottling room 107.
the pressure relief valve 212 may also be connected to an outlet to release the excess air to outside the bottling room 107.
the pressure relief valve 212 may for example be a gravity controlled pressure relief valve with a counterweight for controlling its opening.
alternative systems based on, for example, springs, electronics, etc. may also be used.
the forced draft fan 209 for providing fresh air to the heating compartment 209, one can better control the flow of air through the furnace. This can further bring the advantage of a possibility to size the two fans 208, 209 larger, such that the air flow through the furnace 204 can be higher and the temperature inside the furnace can be better controlled.
the furnace may comprise control means (not shown) configured to control the induced draft fan 209 and the forced draft fan 208 such that the amount of hot air withdrawn from the heating compartment 205 is smaller than or equals the amount of fresh air provided to the heating compartment.
control means not shown
Such a configuration allows to further improve control of the air inside the bottling room as it can be prevented that air inside the bottling room is drawn into the furnace and through the exhaust such that, for example, the overpressure inside the bottling room could be decreased.
the overpressure inside the bottling room 107 is maintained by the air conditioner 1 15, which takes air from an air inlet 215 in the bottling room and another air inlet 216 outside the bottling room, e.g. in the second technical room 109 and supplies conditioned air at overpressure through an outlet 217 in the bottling room 107.
the air conditioner 1 15 takes air from an air inlet 215 in the bottling room and another air inlet 216 outside the bottling room, e.g. in the second technical room 109 and supplies conditioned air at overpressure through an outlet 217 in the bottling room 107.
the bottle forming unit 300 comprises a furnace
furnace may be interpreted widely and may comprise various devices, e.g. a device as described herein, for increasing a temperature of the body of a preform.
a furnace may herein also be indicated by using the terms “heating furnace”, “oven”, or “heater”.
the bottle forming unit 300 further comprises a moulder 306 for moulding the heated preforms into bottles.
the moulder preferably is a blow-stretch moulder, which may be regarded as a type of blow-moulder.
a blow-stretch moulder may be preferred because it may enable forming relatively large bottles from relatively small preforms, as a result of the combined action of stretching and blowing.
a blow- stretch moulder may be relatively compact. Because part of the extension of a preform into a bottle may be achieved by means of the stretching, a blowing pressure may be reduced. Thus, a size and/or power consumption of a part of a driving unit for driving the moulder may be reduced.
a blow-stretch moulder may combine well with a bottle forming unit for forming bottles from bottle preforms that is to be positioned inside a transportable container, where relatively few space is available for placing the bottle forming unit and/or where a decrease in power consumption may be appreciated.
the moulder 306 comprises a driving unit 322 for driving, i.e. opening and closing the two mould halves 351 , 352 of the moulder.
a driving unit may e.g. comprise a hydraulic, pneumatic or electric drive.
the driving unit 322 is positioned inside a loop 31 1 along which the carriers 308 can be transported, so that the space inside this loop is used efficiently.
the driving unit may need to sustain relatively strong forces, because the mould needs to be kept closed in spite of the pressure of the blowing air inside the mould.
the driving unit therefore is preferably relatively powerful and/or sturdy, and therefore may be relatively heavy and/or relatively voluminous.
fitting at least the driving unit, or at least part of the driving unit, inside the loop 311 may bring a reduction of the footprint of the transportable bottle forming unit when placed in the container.
the bottle forming unit further comprises the transporter 302 arranged for moving the bottles and/or the preforms.
the transporter may alternatively be indicated herein by the term "transporting unit” or "transporting means”.
the transporter 302 comprises a plurality of movable carriers 308.
the carriers 308 are arranged for carrying the preforms and/or the bottles. Thereto the carriers 308 are each provided with at least one holder 324 arranged for holding a preform or a bottle. Thus, each carrier 308 may be arranged for carrying at least one preform or bottle.
the carriers 308 preferably have a substantially rectangular shape, preferably with rounded corners, though other shapes are possible.
the holders 324 are preferably arranged for holding the preforms and/or bottles at a neck of the preforms and/or bottles.
the holders 324 are preferably arranged for holding the preforms and/or bottles with the neck of the preforms and/or bottles directed downwards.
the preforms preferably undergo an additional step to push them firmly onto the holders 324, herein also called "mandrels", and are preferably subject to UV light for sterilisation in UV light box 317.
the necks for the preforms are substantially shielded from heat supplied by the furnace.
the furnace may e.g. be provided with heat shields and/or heating elements positioned to achieve such shielding.
the transporter 302 further comprises guiding elements for guiding the movable carriers 308 along the loop 31 1.
guiding elements may e.g. comprise a rail to which the carriers may be movably mounted and along which the carriers may be transported, or guides between which the carriers may be transported.
the guiding elements define the loop 31 1 of carrier positions where a carrier may be positioned.
the loop may have more than four corners, e.g. six or eight corners with then e.g. hexagonal or octagonal carriers.
the loop may have another shape.
a part of the loop in between two corners may be curved.
the loop 31 1 is provided for moving the carriers 308 through the furnace 204, for moving the carriers from the furnace 204 to the moulder 306, and for returning the carriers from the moulder 306.
the loop may be provided for moving the carriers through the furnace 204 over a part of the loop that extends from one corner 312.1 of the loop to a next corner 312.2 of the loop, located directly downstream of said one corner. This distance is defined by at least the length of the furnace 204 along the loop.
the furnace may optionally be arranged along a long side and the moulder may be arranged along a short side, while the short side is preferably kept as short as possible taking into account the size of the moulder and the capability to remove the formed bottles from the carriers by means of the second transferring device 142 along that same short side.
an advancer may be formed as a pusher.
An advancer may e.g. comprise a piston having a plunger or may comprise another pushing element.
An advancer 314 is typically arranged for moving a carrier 308 positioned at a corner 312. i away from that corner 312. i, as shown in figures 8A-D.
the carriers 308 are, in use, pushed stepwise from one carrier position to a next carrier position by means of the advancers.
the rectangular loop shown in figures 7 and 8 needs four pushers, one located at each corner for pushing the carriers into and further along a part of the loop downstream of the corner towards a next corner.
Figure 8A schematically shows the transporter 302 in a situation where carrier positions at a first set of two diagonally opposed corners 312.2, 312.4 are free of a carrier 308.
Figure 8C schematically shows the transporter 302 in a situation where carrier positions at a second set of two diagonally opposed corners 312.1 , 312.3 are free of a carrier 308.
the number of carriers 308 the number of carrier positions may be adjusted so that at least two, and preferably at most two, i.e. preferably exactly two, carrier positions along the loop 31 1 are free of a carrier 308.
Said at least two carrier positions may in use be positioned at diagonally opposed corners of the loop 31 1.
at least two free, or, in other words, vacated, carrier positions may be positioned at diagonally opposed corners of the loop 31 1.
a trailing carrier of said file of carriers 308 is moved into said next corner 312J.
the term "row” may generally be used.
Figures 8B and 8D show the transitional stages between figures 8A and 8C, with each time the file of carriers 308 being advanced halfway between the corners 312. i.
the transporter 302 is provided with a controller 318, arranged for controlling the advancers 314. i.
the controller is arranged for controlling the moment of advancing of the advancers 314.
the controller is drawn in figure 7 together with data transmission lines 319, arranged for communicating controlling signals from the controller to the advancers, and possibly for receiving a feedback signal from the advancers to the controller.
feed-back signals may e.g. relate to a position of the advancer, in particular to a position of a plunger and/or piston of the advancer.
the controller may be arranged for simultaneously moving, by means of the advancers, carriers 308 positioned at the diagonally opposed corners of the loop from those corners.
the controller 318 may be arranged to operate the advancers 314. i so that two advancers located at diagonally opposed corner positions of the loop operate substantially simultaneously. As a result of such operation, the two advancers vacate carrier positions at the diagonally opposed corners, i.e. at the corners where the advancers are located.
the controller 318 is further arranged for advancing the carrier 308 positioned at the next corner 312J subsequent to advancing the corner positioned at the first corner 312. i, so that alternating operation of the advancers 314.1 and 314.3 together alternating with 314.2 and 314.4 together may be achieved.
the controller 318 may further have transmission lines 319 towards the moulder 306 and the first and second transferring devices 141 , 142 of which the first is arranged for placing preforms onto the carriers and the second is arranged for removing formed bottles from the carriers.
the controller 318 is capable of controlling operation of these components so that their operations occur at standstill of the respective carriers 308.
the advancing of the carriers through the furnace 204 may occur simultaneously, or substantially simultaneously, with a bottle forming step in the moulder 306 and a formed bottle removal step at the second transferring device 142.
advancing the carriers 308 through the mould may occur simultaneously, or substantially simultaneously, with a step of placing a preform on a carrier by the first transferring device 141.
the carriers 308 may have a first dimension D1 and a second dimension D2, the first dimension D1 being larger than the second dimension D2.
the first dimension and the second dimension may be measured in mutually transverse directions.
the first dimension D1 is sufficiently large for allowing space for blown bottles on subsequent carriers.
the second dimension D2 is sufficiently large for allowing space for preforms on subsequent carriers, but is shorter so that the time of the preforms in the furnace is maximised. This may enable a gradual and/or uniform heating of the preforms in the furnace 204. More in general, a number of preforms per unit of length along the loop in the furnace may be larger than a number of bottles per unit of length along the loop on the side of the mould.
the inventors therefore prefer to keep a path from the moulder 306 to the point of removal of the bottle, i.e. to second transferring device 142, as short as possible.
the inventors therefore prefer to move the carriers relatively fast on the path from the moulder up to bottle removal, yet they prefer to move the carriers at a lower speed during their path through the furnace. This may be achieved by providing the carriers 308 with the first dimension D1 and the second dimension D2 as described above.
the heated preforms are moved from a position just outside the furnace to a position suitable for blowing a bottle, namely the position in between the mould halves 351 , 352.
the formed bottle is preferably removed from its carrier as soon as possible after it is formed, i.e. after as few steps as possible removed from the position of the carrier during the forming step, i.e. the "forming position".
the inventors have found that removal of the bottle from the carrier may be provided from the position which is only two steps downstream of the forming position. The removal from this position allows improving the space utilization of the bottle forming unit 300.
the inventors have found that two empty corner locations along the rectangle may be provided at diagonally opposed corners.
the inventors have found that in an arrangement having at least four corners and with two empty corner positions along the loop, the two advancers at diagonally opposite corners may operate simultaneously, optionally in concert with the two other advancers also operating simultaneously. With this operating sequence, the speed of movement of the carriers along the loop may be significantly increased. This may lead to a significantly increased production rate of blown bottles, and hence also of filled bottles. E.g. with the two empty corner positions, the bottle forming unit 300 can achieve a production rate of approximately 1800 bottles per hour.
the inventors prefer to leave the heated preforms on their mandrels and move them altogether into a suitable position for forming the bottle using the mould.
a loop enabling an improved space utilization compared to US 201 1/0302881 may be combined with an improved production rate of bottles compared to WO 201 1/095464. Such combination may be appreciated in view of a limited space available in a container, e.g. a standard 20 foot freight container.
the transporter of the bottle forming unit may also be composed of carriers comprising each time two preform/bottle holders, as known from WO 201 1/095464, but with two open positions in the rectangle, so with the same operation as shown in figures 7 and 8, and preferably also with the preforms held upside down.
the carriers are rectangular and oriented such that the two preforms move parallel to each other through the furnace 204, i.e. in two rows, and in one row on the side of the mould 351-352.
the mould may be arranged for forming two bottles simultaneously and also the preforms may be placed two by two simultaneously on the carriers and the bottles may be removed two by two from the carriers.
the advancing of the carrier file on the side of the mould 351- 352 may also occur in two substeps with a standstill halfway, so that the same mould 351-352 and second transferring device 142 as shown in figure 7 may be used, i.e. for handling the prefroms/bottles one by one.
the bottling plant 100 shown in figure 9 comprises a product inlet 400 for connecting a product supply for supplying the product to the bottling plant, a product circuit 410 comprising a plurality of conduits and components fluidly connecting the product inlet to at least one product outlet nozzle 409 (preferably two, see above) in the filling unit 1 19 at which the product is filled into the bottles, and an arrangement 411 -415 for drying the product circuit after a period of operation of the bottling plant 100.
this arrangement for removing residual product from the product circuit comprises at least one valve, in the embodiment shown four valves 41 1-414, with each time a connector for connecting a pressurized air conduit of a pressurized air conduit system, via which the product circuit 410 is connectable to a pressurized air supply 415 for forcing the residual product from the product circuit by means of pressurized air.
the valves 41 1-414 each time a connector for connecting a pressurized air conduit of a pressurized air conduit system, via which the product circuit 410 is connectable to a pressurized air supply 415 for forcing the residual product from the product circuit by means of pressurized air.
the valves 41 1-414 each time a connector for connecting a pressurized air conduit of a pressurized air conduit system, via which the product circuit 410 is connectable to a pressurized air supply 415 for forcing the residual product from the product circuit by means of pressurized air.
valves 41 1-414 are normally closed during the filling operation. After a period of operation, e.g. as soon as the filling operation is stopped and will not be resumed for a longer period of time, e.g. at the end of a day, the valves 41 1- 414 are opened, so that pressurized air is released into the product circuit 410, preferably at many locations, in the embodiment shown four locations, so that the residual product is forced from the product circuit 410. In this way, rest product is removed and any bacteria growth in the product circuit during a period of standstill may be suppressed.
pressurized air over e.g. steam has the advantage that wear to the components of the product circuit 410 may be minimized and that the risk of a dead bacteria film remaining inside the product circuit may be minimized.
pressurized air over e.g. steam has the advantage that the need for a separate unit to generate the steam is avoided, as the pressurized air supply 415 may conveniently comprise the air compressor 113 which is readily present on the transportable bottling plant for providing the pressurized air for the bottle blowing process.
This pressurised air is of high quality, which further reduces the risk of wear to the components of the product circuit.
the air compressor may be arranged for supplying pressurized air at a pressure within the range of 15-25 bar, which may be reduced to a pressure within the range of 2-10 bar, preferably 4-6 bar upon injection into the product circuit.
the air compressor 1 13 may be provided with the air dryer 1 14 for drying the pressurized air to a dew point for example below 5°C, preferably below 4°C. This can help to ensure sufficient removal of the residual product, e.g. water, from the product circuit to avoid bacteria growth during idle periods. In the case of water, a time period of e.g. about 2 minutes can be sufficient for removing the residual water as desired.
the product circuit 410 may comprise, in succession from the product inlet 400 to the at least one product outlet nozzle 409, the following components: an infeed pump 401 for pumping in the product, a flow meter 402, at least one filter stage 403, 404 for filtering the product, a buffer tank 405 for buffering the product, a UV treatment unit 406 for subjecting the product to UV treatment, a dosing pump 407 for dosing the product towards the product outlet nozzle and another flow meter 408.
the filter stages 403, 404 and the UV treatment are used for obtaining potable water from freshwater and the flow meter 402 may be used for controlling a chlorine adding device, to add a correct dosage of chlorine to the freshwater.
This filtering and treatment process is well known in the art and therefore needs no further description here.
the product inlet 400 may be part of a centralised product infeed and discharge system provided in an outside wall part of the freight container, behind hatch 129.
the bottling plant 100 may be provided with an inlet and an outlet for circulating a cleaning product through the product circuit, which may for example be the product inlet and outlet of the centralised product infeed and discharge system, behind hatch 129.
a heating device (not shown) may be provided at the product inlet for heating the cleaning product, so that its efficiency (e.g. the speed and/or the effectiveness of the cleaning operation) can be improved.
rinsing product e.g. water or an alternative rinsing product
the heating device which may be provided at the product inlet, may also be used during this rinsing step to heat the rinsing product, so that subsequent drying of the product circuit may be facilitated (as the product circuit is brought to a higher temperature before drying).
bottle forming unit 360 is in many respects similar to the bottle forming unit 300 of figures 7 and 8. Like parts have been indicated with the same reference numbers and will not be described again in detail for the sake of brevity.
the bottle forming unit 360 differs in the following aspects from the bottle forming unit 300.
the moulder 306 is the bottle forming unit 360 is fitted with mould halves 361 , 362 for blowing bottles of oval shape, such as for example bottles for holding detergents.
additional preheaters 364 are provided at the carrier position right before the mould, for additionally preheating the sides of the preform facing the mould halves 361 , 362 and facilitating expansion of the preform material in the direction parallel to the mould halves.
the bottle screw cap which is in this case usually of the type having a snap closing part hingedly connected to a base part, is always placed in the same direction on the bottle.
the preforms and in particular the screw-thread on the necks can always be oriented in the same way on the carriers before they are expanded to become the oval bottles.
the orienting of the preforms is in the embodiment of figure 10 performed at the carrier position just outside the oven 204, by means of an orienting device 363.
This orienting device is provided for rotating the holder 324, for example by acting on a gear provided on the carriers 308, and is equipped with a sensing element for sensing the recess on the preform.
This principle, and suitable orienting devices are known in the art and therefore need not be further described here.
the orienting device 363 may also be provided at other carrier positions between the furnace and the mould, for example in the corner position 312.2, or in case the preforms are not rotated in the oven (the necessity of which may depend on the heating principle used) the orienting device 363 may be even located at other carrier positions along the transporter 302.
the bottle forming unit 360 of figure 10 further comprises a bottle marking device 365 located adjacent to the transporter 302 at a carrier position downstream of the mould, for example the carrier position just after the mould.
the bottles can be marked (i.e. provided with a mark containing e.g. a date and time of production, a product code, ... ) while still on the transporter 302 of the bottle forming unit 360, which is convenient since a stable position of the bottles is desired for the marking step.
the addition of the marking device 365 also does not require a larger transporter 302 or more carrier positions as compared to the bottle forming unit 300 of figure 7, so space can be saved.
An additional exhaust conduit may be provided leading from the carrier position at the bottle marking device 365, i.e. where the marking step occurs, to the hot air exhaust conduit, the additional exhaust conduit being provided for withdrawing fumes created upon marking the bottles by means of the bottle marking device 365, which may for example be a laser device.
the bottle marking device 365 which may for example be a laser device.
a transportable containerized plant as described herein may provide a solution to reduce operating, personnel, fuel and transportation costs. It can be used for several applications:
a transportable containerized plant can be used e.g. as back-up for a permanent plant; in case the latter has insufficient capacity, in case of break down or maintenance or to produce a new product without jeopardizing the production continuity of the permanent plant.
a containerized plant is a fast solution.
the containerized bottling plant has an extremely short installation and start-up period, it can be prepared for immediate shipment worldwide and it is a plug-and-play system.
the risk on investment is low as compared to the risks involved with stationary plants because the bottling plant is transportable to other regions in case of local problems.
the risk on quality problems is low since damage of products is inferior when products are bottled and/or packed locally compared to long distance transport.
a containerized plant is an economic logistical solution since the costs are inferior when a product is bottled and/or packed locally compared to long distance transport. Also, import taxes can be diminished in many occasions.
