Definitions

  • the invention lies in the field of transport technology in high-speed product manufacture and relates to a product transfer process in connection with a manufacturing process, in particular the transfer of a product output from a machine and the time-dilated transfer to the next manufacturing step.
  • the product transfer process is aimed at the production output of goods packaged in flow-pack processes.
  • a typical high-speed manufacturing process for example in chocolate production, begins with the raw materials, which usually get into the production process from the silo storage via automatic feeders. Mah - len, mixing etc. is fully automated, and the mixing and stirring are usually automated production processes.
  • An intermediate batch operation e.g. emptying the agitators into containers with a capacity of up to 78 tons of chocolate, interrupts the continuous flow of material, but does not change the high mass potential of the manufacturing process.
  • the first bottleneck problems with high material throughput can be seen in the subsequent injection or casting process, in which the unshaped mass is to be given a lumpy shape, that is to say divided into portions.
  • the material flow thanks to the amorphous presence of the intermediate products, is included simple means, mostly through pipe connections which enable relatively simple pipelining, which is particularly well suited for fully automated mass transport, can be used for the lumpy products, or better for the portioned product, for example for lumpy hard coal that can also be transported by pipeline. to distinguish, can no longer be transferred using the bulk goods transport methods.
  • each spraying line is therefore followed by several packaging lines operating in parallel, in which the chocolate bars (portions) produced in this example are packed using a flow pack process developed for high packaging speeds. As a rule, the flow pack strand is then cut into the intended portions and the loose individual products are collected in some way.
  • Process-inherent order means the following in a value-free view. Different processing steps take place in different places, which may be very close to each other or very far apart. The material must be conveyed from one processing step to another. For example, changes in position or the like are to be carried out. They are to be understood as a follow-up operation to the next process step and represent a certain (transient) order in the overall flow. A disturbance of this order interferes with the process, a cancellation of this order blocks the process. These interventions can be understood as "introduced" elements of order. The process-inherent organizational elements, on the other hand, are implicit (actually already) and have to be specifically sought in order to make them usable.
  • the object of the invention is to provide a method for further processing a packaging assembly, for example a flow pack, in which the transport options of the packaged material are significantly expanded and which particularly supports a high-speed manufacturing process. Furthermore, it is an object of the invention to provide an apparatus for performing the method.
  • the problem of further processing arises, for example in a mixed product mix Street 6 and / or intermediate storage in, for example, an intermediate storage 5 for later processing in a mixed-mix line.
  • This temporary storage serves as a time buffer.
  • a transport can be provided that extends over a shorter or longer distance.
  • the method according to the invention now allows such intermediate buffers to be carried out almost arbitrarily by using process-inherent order elements, in which, when they are used, the transfer speed can be reduced with full product output and, on the other hand, the portioned material flow can be shut down in a certain spatial arrangement.
  • FIGS. 2a / b show a typical tubular bag packaging with portions 28A to 20E etc. from two viewing directions, which are accommodated in a “packaging tube” 22.
  • the individual portions are separated from one another in the packaging tube by sealing zones 21A to 2ID etc.
  • a cutting device separates the flow pack assembly 22 from the portions approximately centrally in the closure zones. Until now, this separation has been considered indispensable, since with an output of 1 to 1.5 m / s the connected flow pack network (material flow) would not be manageable.
  • a feeding means 34 sketchy illustrated with a gripper 35 at its free end, then moves with a speed approximately to v1 the flow-pack composite to a running over a deflection wheel 38 conveyor chain 27 having a number equidistant hooks 36 and transfers the flow-pack composite at certain Locking zones 21 on the hooks 36 of the conveyor chain 27.
  • the degree of deflection of the hauling device 34 determines the loop length and the “duty cycle” hook 36 / no hook 36 is adjustable and determines the folding density on the one hand and the vl / v2 transformation on the other hand.
  • the transformation is 1.2: 8.2, i.e. a slowdown to 1/6 times. Doubling the number of hooks would result in a further halving of the speed.
  • the packaging composite as it comes from the flowpack machine, would not allow the packaging composite to be conveyed away in any spatial direction in almost any curved path. This is only possible if it is brought into the special arrangement (loops) proposed here.
  • the stretched packaging assembly running out of the packaging machine is not readily deflectable, at least in all directions which lie in the plane of the "flat" assembly. Only deflections from the plane are possible, this also includes, for example, twisting the band-shaped composite for a lateral deflection. This limitation does not apply to the loop arrangement according to the invention. Shortly after the formation of the loops, the new arrangement of the packaging strand can be conveyed away in any direction, for example in a relatively small radius that is only limited by the conveyor chain.
  • FIG. 4 now shows a further manipulation of the flow pack assembly with a schematically illustrated device for carrying out this manipulation. If, for example, the length of the loop is adjusted with the hauling device 34 forming the first loops so that the material flow can be passed from one room to the other through an existing wall opening, for example, This loop length (short) may no longer be optimal for further processing such as buffering etc.
  • Another loop manipulation to be discussed now changes the length of the loops; it involves the operation of doubling the loop length.
  • An auxiliary device 40 which in principle is configured like the main device, with an endless chain 42 with hooks 46 running over deflection wheels 41, 41 ', serves to take over certain flow pack loops.
  • the process-inherent element of organization is the suspension of the loops, which is used every second suspension.
  • the function according to FIG. 4 is as follows: the flow pack loops conveyed in the direction of the arrow zl are transferred in a clocked ratio from the main line of the main device to a secondary line of the auxiliary device (major loop / minor loop), i.e.
  • every second loop of the flow pack assembly is transferred to the hooks 46 of the auxiliary device 40, from where this loop point is conveyed synchronously at a certain angle of inclination in the direction of arrow z2 up to the lower apex of the new (extended) loop .
  • the hooks 46 of the auxiliary device which work in the undergrip, are unhooked, since positional advantages are treated as process-inherent organizational elements in the 3-D promotion. So no additional order element (with additional device parts nota bene) is introduced into the process. It is irrelevant whether the deflection wheel 41 is arranged as the end of the secondary line at the hanging point, in its vicinity or further away.
  • the loops of the underhand grip are released by the divergent path in the direction z2. An unnecessary extension of the transport chains is of course avoided due to cost considerations, therefore the auxiliary device shown should be practical.
  • the retrieval device 44 shown in FIG. 4 can work on a storage device shown in FIG. 5 for automatic storage and retrieval of the still uncontaminated flow pack assembly. 5, the hanging flow pack loops are arranged in a spiral, for example with a device shown in FIG. 6.
  • the example of chocolate production discussed here is used.
  • a warehouse network of only 2m in height and 2m in diameter comprises around 30,000 chocolate bars with a total weight of over 3 tons.
  • the original process-inherent organization elements are still present, e.g.
  • the bearing shape according to FIG. 5 is only one of several options for arranging flowpack loops in a space-tight manner.
  • the form shown is mainly suitable for temporary storage, where the first-in-lastout aspect does not play a role in the event of reactivation.
  • a space-saving buffer can be created within a manufacturing process, which is able to buffer up to 10 (?) Tons of flow pack compound during the manufacturing process, ie without having to slow down the process. While high-speed processes can take place in the sections before and after the buffer, the transfer speed of the material flow can still be reduced as desired until it comes to a temporary standstill without the flowpack network, which can be hundreds of meters long, having to be separated.
  • FIG. 6 now shows a very simple device with which a spirally arranged flow pack assembly, as shown in FIG. 5, can be created.
  • the essential parts of the device consist of a drive base 60, in which the foot 61 of a rotatable stand 62, which at its other end carries an arrangement of the transport means 67, formed as a flat spiral, with sensors 66 on a carrying spider 63.
  • the drive base is equipped with an electric motor, not shown here, which drives the foot 61 of the rotatable stand 62 via a gear (also not shown), as is done by two rotating arrows is indicated.
  • the catch-up device 44 is provided to be tracked from pickup to pickup similar to the tonearm of a record player.
  • the hauling-in device 44 (FIG. 4) is positioned near the center 64 of the flat, synchronously rotating spiral of the means of transport, so that the top of the loop begins to take over at the innermost pickups and ends at the outermost ones, for example at the terminal 68.
  • the loops suspended in this way then form a spatial network as shown in FIG. 5.
  • FIG. 7 shows an aid for the transport of covered and empty stands.
  • the fastening and holding means 65, 65 'shown in the two FIGS. 6 and 7 are strong bolts with an eyelet on one end and a screw thread on the other end.
  • Appropriately dimensioned rods of a lifting device can be inserted through the eyelets for inserting and lifting out the stand, with which the stand can be lifted from the drive base onto the pallet body 78 so that it cannot tip over.
  • the foot part 61 can be secured in the pallet body by screwing the bolts 65 into the threaded holes 65 '.
  • the drive base 60 would be part of the loop system and the stands would be a kind of return container.
  • the variety of stands can be produced inexpensively, including the pallet body, which can be used for transport and storage. In special storage rooms, threaded holes in the floor and shallow centering recesses, which make insertion easier, can save on pallet bodies.
  • the emptying of a fully or partially hung stand takes place in the reverse operation as the hanging and in principle with the same devices.
  • the loop vertices are taken over by the pick-up of another means of transport and transported away for further processing.
