Definitions
- the present invention relates to a method and a device for filling a flexible container, in particular a bag, with pourable materials and in particular with bulk materials, wherein the flexible container is filled by means of a filling member.
- the invention is used for filling of powdery products or granules and in particular for filling light and very fine powder products, such as aerosils, as well as used for color production carbon black particles or TiO 2 particles or TiO 2 containing materials or the like, in which the bulk material during filling contains a considerable amount of air.
- the invention is also suitable for filling other pourable or flowable materials or for filling toxic or environmentally hazardous products.
- US 3,533,454 discloses a device with which materials are filled into sacks.
- the lateral surfaces of the bag are first pressed in.
- the side walls are then expanded so that the pored sidewalls of the bag do not become clogged during the filling process by the filling material.
- the filling rate can be increased during filling.
- This known technique only leads to a relatively small shortening of the entire filling process, because this is considerably determined by the maximum pressure in the bag at the end of the filling process and the resulting waiting time after the end of the filling process. Since the maximum pressure is unchanged, the waiting time remains unchanged and only a small shortening of the filling process is achieved.
- a bagging machine for filling powdery goods has become known with a filler neck, in which at the filler neck provided with a filter and connected to a vacuum source air outlet opening is provided which serves to extract the air contained in the bag.
- powdery bulk materials can be filled into valve bags.
- a disadvantage of the known device is that when using a coarse-pore filter material still a significant proportion of contents is discharged through the outlet, while using a fine-pored filter material, the pores quickly through the contents, so that the effect is significantly reduced.
- the sack In such devices known from the prior art, wherever the product can escape with the air, the sack must therefore be overfilled with the expected weight loss in order to reduce or compensate for the weight deviations of the filled sack. But since this weight loss varies, a greater spread of the weights is inevitable, which must be filled to maintain a minimum weight usually more material in the bags, as would actually be necessary. Alternatively, the settling time can be extended after the end of the filling process to reduce the overpressure.
- the method according to the invention is intended for filling flexible containers with pourable goods and serves to preferably for filling sacks with in particular light pourable goods.
- the container to be filled is filled with a filling member or with several filling members by means of a filling process.
- the filling process comprises at least one filling section, a calming section and a removal section.
- the volume of the container and in particular the volume available to the container is increased according to the invention in order to reduce the pressure prevailing in the container.
- At least one pourable material is filled into the container, in particular with the addition of air.
- At least one calming-down phase is provided in the calming section for depressurization, and in the detaching section the container is removed from the filling device.
- a welding of the bag can take place.
- the filling process according to the invention is shortened by the fact that the available volume of the container is reduced during a substantial part of the filling process in order to keep the pressure prevailing in the container high during filling. At the end of the filling process, the available volume of the container is increased in order to quickly reduce the pressure prevailing in the container.
- the term "filling process” is understood to mean the process from attaching or arranging the container to the removal or removal of the filled container of the filled container.
- filling process is understood to mean the process of filling, that is to say the filling section.
- the term “during the filling process” is understood to mean that the volume in terms of time after the start of the filling process Filling process, that is done after arranging or plugging and before the removal of the container.
- Another significant advantage of the invention is the increase in volume at the end of the filling process, whereby the overpressure is reduced accordingly.
- the pressure prevailing in the container is reduced directly in proportion to the increase in volume, so that with the increase in volume directly a pressure reduction is achieved since the flexible container will immediately take up the increased volume due to the increased internal pressure. Consequently, the decompression pressure can be reached quickly, so that when the containers are removed, there is no high loss of material, since the pressure inside the container is reduced by the increase in volume.
- Another advantage of the method according to the invention is a better bag ventilation already during the current filling process.
- a bag starts to vent when there is overpressure, ie when there is a pressure difference to the environment. This time typically occurs from about 50% of the weight to be filled. Due to the fact that initially only a reduced volume is available in the method according to the invention, the pressure level in the bag rises steeper during the filling process than in a conventional method, so that an overpressure in the bag is achieved at a considerably earlier point in time, which is an automatic bag venting causes. Since the venting rate of the container depends on the pressure difference between the interior of the bag and the environment, there is optimal ventilation due to the high overpressure level prevailing during the filling section. The venting of the container is significantly accelerated.
- the area under the curve is a measure of the work of venting. This area, which refers to the period of the actual filling, is greater in the inventive method, so that according to the invention a faster filling can be achieved.
- the volume is increased towards the end of the filling process, in particular at the end of the filling section or in the settling section after the filling process has ended, while the container is still arranged on the filling nozzle or the filling member.
- the volume available to the flexible container is increased immediately after switching off the filling element, this means a directly proportional reduction of the internal pressure in the container so that the container can either be removed directly or the required waiting time is considerably reduced.
- the duration of the settling phase was reduced from about 20 seconds to 5 seconds, while the duration of the filling section remained constant at about 30 seconds, so that the time for the filling process could be reduced by 20 to 30%.
- the available volume is kept substantially constant during the filling section.
- a predetermined pressure in the container is built up quickly and then held approximately during the filling.
- the built-up pressure can be the maximum buildable Pressure or a pressure that is chosen in compliance with safety tolerances.
- the available volume can be increased in the calming section only after a calming phase to promote the venting.
- the pressing jaws are preferably pressure-controlled.
- the contact pressure of the pressing jaws in the calming section is first increased for a period of time before the available volume is subsequently increased by reducing the contact pressure of the pressing jaws.
- the ventilation is further enhanced at the elevated pressure level, so that the calming section can be shortened.
- a characteristic value for the weight of the container or of the contents contained in the container is detected during the filling process, in particular during filling or during the filling process at periodic intervals or continuously.
- the weight can be determined via a net method, and particularly preferably a gross method. It is also possible that a bag chair, on which the container is arranged, is part of the weighing system. Since the weights of the components involved are known, it is possible to deduce from the measured total weight on the current weight of the contents contained in the container back.
- the feed of the bulk material is stopped.
- a weight-dependent control of the filling process or the filling process wherein the filling rate when reaching a predetermined Weight or weight fraction of the coarse flow rate is reduced to the Feinstrom sleeprate.
- the filling rate can also be lowered continuously on reaching a predetermined weight or weight fraction up to a minimum filling rate in order to achieve optimum filling.
- the volume available to the container is increased when a predetermined weight or a predetermined proportion by weight is reached.
- the increase in volume can take place in particular abruptly or approximately abruptly.
- the available volume in the calming section may be in a short period of time, e.g. be enlarged in one step or abruptly. Also possible is a continuous increase in volume after completion of the filling section.
- the volume available to the container can be limited initially preferably by lateral limiting devices, pressing devices, pressing jaws of the like, the pressing jaws or the like to increase the available volume of the container then at the end of the filling process and in particular be driven outward in the calming section.
- the limiting devices or pressing jaws or the like act on the longitudinal sides of the container.
- the pressing device can initially limit the volume available to the container, so that it is smaller than the possible volume of the container.
- the pressing devices or the like can then be removed from the container or moved away, so that the container expands due to the prevailing internal pressure, as a result of which the internal pressure in the container is reduced accordingly. is graced.
- the enlargement of the volume available to the container can take place abruptly or continuously or stepwise.
- the volume available to the container is increased by up to 50% or more, in particular by up to 30%.
- the volume increase is between about 3% and 20% and more preferably between about 5% and 15%.
- the percentage of particularly fine and light fabrics may be even greater.
- the internal pressure is about 1.1 bar.
- the overpressure contained in the bag can be completely reduced, for example.
- an almost complete pressure reduction can be achieved even with a volume increase of 10%, if after stopping the filling a short waiting time is inserted, within which the pressure is automatically reduced by the openings contained in the bag by a certain amount.
- the waiting time and the calming section can be shortened considerably.
- the waiting time is inserted and then the volume is increased, since the pressure reduction in the preceding period is faster at higher overpressures.
- a characteristic value for the filling pressure in the container can preferably be detected by means of a pressure sensor.
- a characteristic value for the air pressure prevailing in the container is determined.
- a probe with a measuring channel can be provided on a filling element designed as a filling tube or filler neck, which extends into the interior of the container to be filled so that a sensor connected to the measuring channel acquires a characteristic value for the pressure prevailing in the container.
- a characteristic value for the pressure prevailing in the container can also be derived via a sensor connected to the filling element or to the container.
- the filling process as a whole or at least the filling process is controlled as a function of the determined characteristic value. This allows compliance with limits during the filling process.
- the filling process is controlled such that a predetermined maximum pressure is not exceeded, e.g. to avoid a sack break.
- the filling member is preferably controlled such that the pressure present in the container or in the bag is as close as possible to the maximum pressure in order to accelerate the filling process as a whole.
- the volume available to the container is varied at least over a period of time as a function of the determined characteristic value for the filling pressure prevailing in the container.
- the decrease in time of the container from the filling member or the filling nozzle is preferably selected as a function of the filling pressure, in order to limit the amount of leaking filling product during the removal.
- valve bags are filled, which are closed after the filling or can also be executed self-closing.
- a diaphragm pump is preferably used to convey the bulk goods.
- the diaphragm pump is basically a machine for the conveyance of liquids or gases, this system has also proven itself for the conveyance of free-flowing goods and in particular of free-flowing goods.
- the operating principle of the diaphragm pump is similar to that of the piston pump, with the diaphragm pump being completely separated from the bulk material to be filled and the drive.
- the separation is achieved by a membrane, by which the moving mechanical components of the engine are shielded from the effects of the bulk material to be conveyed.
- the actual mechanical drive of the diaphragm pump can conventionally be effected via an electric motor by means of a connecting rod fixed to the diaphragm or by means of suitably controlled compressed air.
- Diaphragm pumps have the advantage over conveyor turbines that they have a lower dependence of the filling capacity on the pressure prevailing in the bag overpressure, so that the prevailing during the filling process increased pressures affect the flow rate only slightly.
- double diaphragm pumps are used, which can also be controlled by compressed air.
- a double housing is provided, which contains two connecting membranes via a connecting rod. The membranes are acted upon on the outside by the conveying bulk material and on its inside by compressed air.
- a valve is actuated, which reverses the compressed air to the other membrane when reaching an end position.
- Such a diaphragm pump controlled by compressed air transfers the air pressure directly to the bulk material to be conveyed. By a Throttling the pressure, the transported amount of bulk material can be adjusted well.
- light bulk material with a density of less than 300 kg per m 3 or with a density of less than 300 g per dm 3 is filled.
- bulk material is filled with a density of less than 250 kg per m 3 and in particular with a density between 30 and 150 kg per m 3 .
- the device according to the invention for filling flexible containers is provided in particular for filling bags with pourable goods and comprises at least one filling member with which a container to be filled is filled by means of a filling process, in particular with the addition of air.
- the filling process comprises at least one filling section, a depressurization settling section and a take-off section.
- a pressing device or a limiting device is provided, with which the volume provided for the container can be changed.
- a control device which is suitable and structured to shorten the filling process by means of the pressing or limiting device, the volume available to the container during a substantial part of the filling process is reduced and greatly increased at the end of the filling section to the filling section to keep the pressure prevailing in the container high and to shorten the calming section after the filling section.
- valve bags can be filled effectively, wherein the volume increase after the filling section enables effective filling of the bags.
- pressing jaws are used as parts of the pressing device, which act on the container from the sides.
- a pressure sensor which determines a characteristic value or a characteristic value for the pressure prevailing in the container.
- the device comprises a comparison device for comparing the pressure prevailing in the container with a predetermined pressure or limit, so that at the end of the filling process, a decrease signal is triggered when the pressure prevailing in the container is less than or equal to the predetermined pressure.

- Fig. 7 is a highly schematic representation of the pressure and the weight over time during a filling process.
- the device 1 shown in Figure 1 according to the invention is embodied here in the embodiment as a rotating packaging machine, which is drivable in the direction of arrow 21.
- the packing machine 1 is used to fill sacks 4 with pourable filling goods 18 and is executed here fully automatically in the embodiment.
- the packaging machine 1 comprises six filling tubes 3, onto which the valve sacks 4 with openings 25 are pushed. As symbolized by the arrow 22 in Figure 1, the valve bags 4 are removed by means of a slip-on device, not shown, or by hand coming from a stock and pushed onto the filling tubes 3 and shot.
- valve bags 4 are filled and removed after reaching the predetermined degree of filling at a predefined angular position.
- the valve of the valve bag 4 is closed and the bags are thrown onto the discharge belt 26, where the actually achieved weight of the valve bags 4 can be checked again before the valve bags 4 are transported away.
- each filling tube 3 is assigned a pressing device 5, which in each case comprises two pressing jaws 5 a and 5 b.
- a pressing device 5 which in each case comprises two pressing jaws 5 a and 5 b.
- the pressing jaws 5a and 5b are moved apart, so that the valve bag 4 can be easily pushed onto the filling tube 3.
- the pressing jaws 5a and 5b are moved from the side of the valve bag, so that the for the valve bag available volume 2 (see Figure 4) is reduced from the beginning of the filling process and is smaller than the possible bag volume of the valve bag. 4
- valve bag 4 During the rotation of the valve sack 4, the sack is filled with the filling material 18 during the filling section 40 until the intended sack weight ml is reached.
- a highly schematized course of the bag weight 30 and of the bag 31 prevailing in the bag is shown over the time T in FIG. 7.
- an overpressure has built up in the valve bag 4, which is typically up to 100 or 250 millibars and may even be greater and depends on the filling material and the other conditions. Due to the overpressure, the sack 4 expands as far as possible and occupies the maximum available volume, which, however, is initially limited by the pressing jaws 5a and 5b.
- the filling process is stopped at time tl when the intended bag weight ml is reached. After a short settling time, during which the inner bag pressure slowly degrades, the pressure can be increased by the pressing jaws 5a and 5b at time t2. The pressure in the bag thereby increases from the pressure 33 to the pressure 34 and then decreases along the curve 37, since the increased internal pressure causes a faster venting of the bag.
- the pressing jaws 5a and 5b are raised during the pressure 35, so that the volume available for the valve sack 4 between the pressing jaws 5a and 5b is increased abruptly.
- the valve bag 4 now assumes its maximum volume due to the overpressure prevailing in the interior of the valve sack 4, as a result of which the pressure prevailing in the interior of the valve sack 4 is correspondingly reduced.
- the inner bag pressure 36 is equal to the take-off pressure pl, so that at the time t4 the bag can be removed.
- an optionally decreases remaining pressure abruptly, so that the ambient pressure is reached, which is illustrated by the point 38.
- the calming section 41 can thereby be considerably shortened.
- the additional pressure increase to the value p3 can, but does not have to be carried out.
- the filling section 40 is usually divided into a section with coarse flow filling and a subsequent section with fine flow filling. For reasons of clarity, this was not shown in FIG. 7.
- packing machine 1 preferably lightweight materials and in particular aerosils, carbon black and other light products are filled.
- other products such as To fill cement or the like with the packaging machine 1 according to the invention.
- FIG. 2 shows another packaging machine 1 according to the invention in a perspective view, which is designed here as a stationary machine and not as a rotating system.
- the sack chair 20 is part of the weighed system in the so-called gross weighing method, in which the sack chair 20 and the pressing device 5 and the valve sack 4 to be filled are weighed in order to move from the determined weight to the filling material 18 contained in the valve sack 4 (see FIG 6), since the weights of the sack chair and the other components involved are known.
- the pressing device 5 comprises a right pressing jaw 5a and a left pressing jaw 5b, which in the starting position e.g. are arranged approximately parallel to each other and spaced from each other and which are each pivotally mounted here at the lower ends of pivot axes 7.
- the two pressing jaws 5a and 5b are connected to each other at the upper ends via an upper linkage 5d, on which a motor 6 is arranged.
- a motor 6 By actuating the motor 6, the upper distance between the pressing jaws 5a and 5b is reduced, so that the volume 2 present between the pressing jaws 5a and 5b is influenced, as can also be seen in particular in the illustration according to FIG.
- another actuator for actuating the pressing jaws may be provided, e.g. a compressed air cylinder or hydraulic drive comprises.
- rotatable bearings at the lower ends of the press jaws 5a and 5b which are respectively provided with press plates 5c, can also be the lower linkage 5e via a motor 6 or other actuator designed to be adjustable in length.
- the pressing jaws 5a and 5b of the sack chair 20 are brought to the valve bag 4 at the beginning of the filling process or the filling process in such a way that they reduce the available sack volume 2 during the filling by, for example. Reduce 10%. That is, for a weight size of e.g. 10 kg only a reduced volume is available.
- the valve bag 4 is initially under the usual pressure of e.g. 100 or 250 millibars or so. At this moment, however, the two lateral pressing jaws are moved apart, so that the volume available to the valve bag 4 is increased virtually abruptly and thus the overpressure is compensated.
- valve bag 4 After moving apart of the pressing jaws 5a and 5b, the valve bag 4 can therefore be removed without a harmful loss of product occurring during the decrease. Consequently, this system allows a high filling performance, since no or only a short residence time is required after the filling process, wherein no 18 or only small quantities are discharged during the decrease.
- the packing machine comprises a double-diaphragm pump for conveying the filling material 18.
- a double-membrane pump 16 is suitable in particular for filling lightweight filling materials 18.
- the filling performance of filling materials having a bulk density of less than 100 g per dm 3 is about 60 sacks per hour and filler, but can also be larger or smaller. It should be noted that not only rotating packaging machines 1 can be provided according to the invention, but it can also packaging machines 1 are used with only one filling tube or with several in-line filling tubes.
- the control of the filling process is carried out by a balance control, which controls the filling speed in dependence on the already present in the valve bag 4 filling weight.
- a higher material flow the so-called coarse flow
- the so-called fine flow is filled with a significantly reduced flow of material until the desired final weight ml of the valve sack 4 is reached.
- FIG. 6 shows a schematic cross section through a filling tube 3.
- at least one pressure sensor 10 is additionally assigned to the filling tube 3, with which a characteristic value for the pressure prevailing in the valve bag 4 can be detected.
- a filling tube 3 is shown cut, on which a valve bag 4 is pushed with its opening 25.
- the valve bag 4 is held with a mounted on an outer side 3 a of the filling tube 3 Blähmanschette 27 and sealed to the environment.
- the inflation sleeve 27 engages an inner wall 28b of a portion 28 of the valve sack 4 which serves to fasten the valve sack 4 to the filling tube 3.
- the volume 2 available for the valve bag 4 is reduced even before the beginning of the filling section.
- the pressure sensor 10 may be arranged in a region 3 c of the filling tube 3, which directly adjoins a region 3d occupied by the section 28 of the valve sack 4.
- the pressure sensor 10 extends through a wall of the filling tube 3, so that it receives the pressure in the interior of the filling tube 3, which essentially corresponds to the pressure prevailing in the valve bag.
- a pressure sensor 10 may be provided which receives the pressure prevailing in the interior of the bag via a pressure receiving opening 9 or a measuring channel or a measuring line 13.
- the pressure receiving opening 9 may e.g. be provided in a front region of the filling tube 3 in the vicinity of the outlet opening for the filling material 18.
- the measuring line 13 may have a first channel 13 as a running portion in the filling tube and a second portion 13 b, which is designed as a flexible or rigid conduit and is connected to the pressure sensor 10. Since pressure disturbances propagate at the speed of sound, the measuring line 13 can have a considerable length.
- the pressure values measured with the pressure sensor 10 are temporarily stored in the assigned digital evaluation unit 11 and transferred to a central control unit 14. Based on the data measured by means of the weighing system 12 and by means of the pressure sensor 10, the filling process is controlled.
- the measured values measured by the weighing device 12 are sent to an electronic processing unit 15, which is connected to the central control unit 14, which controls the conveying member 16.
- air may be supplied via an air supply 17, e.g. Caking to solve.
- the filling process works as follows. After attaching a valve sack 4 by hand or with a clip-on machine to a filling tube 3, the valve sack 4 is fixed by means of the sloshing sleeve 27 and the squeezing jaws 5a and 5b are brought to the sack in order to control its available volume. limits. Subsequently, the filling process is started, which is controlled by the electronic control unit 14 and in which the filling material 18 and at the same time an air portion 19 are introduced into the bag 4.
- the filling material 18 supplied to the conveying member 16 from a silo or the like is introduced through the filling tube 3 into the valve bag 4.
- the amount of filled material 18 is continuously detected by the weighing device 12 shown only schematically and the measured values are forwarded to the processing unit 15 and the control unit 14.
- the pressure prevailing in the valve bag 4 is detected. If the pressure in the valve bag exceeds a predetermined limit, the filling process is slowed down to avoid bursting of the valve bag 4. Conversely, the filling rate can be increased if the pressure prevailing in the valve bag is less than a predetermined pressure.
- the position of the pressing jaws is controlled as a function of the current weight and the determined pressure in the valve bag 4. It is possible, e.g. that the pressing jaws 5a and 5b first reduce the volume available to the bag when a predetermined proportion of e.g. 30 or 50% of the intended capacity was filled in the bag. It is also possible, the pressing jaws 5a and 5b after the end of the filling process continuously to move apart to increase the volume available to the bag continuously.
- the pressing jaws are moved apart after the filling process, so that the pressure in the bag interior drops abruptly.
- the over-pressure determined inside the bag falls below a predetermined or selectable value, the bag is removed. Since there is no or only a slight overpressure during the removal, only very little or no filling material 18 is blown out of the bag during the removal, so that the sacks 4 and the packaging machine 1 remain cleaner.
