Definitions

  • the invention lies in the field of product transport technology in a high-speed product manufacturing and packaging process and relates to a product transfer process within the overall 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.
  • CH-A-559'691 shows how the scale flow of non-contiguous printed products is wound on so-called drum bodies with the help of holding straps over a horizontal axis of rotation in the printing shop.
  • the straps are needed to hold the loose print products together.
  • the wound printed products are fed to an intermediate storage.
  • EP-A-0'243'753. has become known a method and an apparatus for processing printed products such as newspapers, magazines and the like which are formed in scale formation. It shows how a pallet loaded with several coils arranged side by side can be tilted by means of a tilting device in such a way that a tower of coils lying one on top of the other is created. Such winding towers are supplied to an intermediate storage.
  • 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. Grinding, mixing etc. is fully automated, and mixing and stirring are usually automated production processes.
  • An intermediate batch operation for example emptying the agitators into containers with a capacity of up to 70 ⁇ 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 on Subsequent injection or pouring process in which the unshaped mass is to be given a lumpy shape, that is to say divided into portions.
  • the material flow can be managed with simple means, mostly through pipe connections, which enable a relatively simple pipelining, which is particularly well suited for the fully automated mass transport, the lumpy products, or better the portioned product, can be around it
  • simple means mostly through pipe connections, which enable a relatively simple pipelining, which is particularly well suited for the fully automated mass transport, the lumpy products, or better the portioned product, can be around it
  • lumpy hard coal which can also be transported by pipeline, 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.
  • the flow pack strand is then provided in the intended Cut up portions and collect the loose individual products in some way.
  • Process-inherent order means the following. 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. Organizing interventions can be understood as "introduced" organizational elements. On the other hand, process-inherent organizational elements are already hidden in the process flow, but must be specifically sought for use.
  • the object of the invention is to provide a method for the transitional storage (intermediate storage) of a packaging assembly, for example a flow pack or tubular bag, in which such order elements are used and thus the transfer of the packaged material into the sooner or later subsequent processing step is significantly expanded, the method should be particularly suitable for a high-speed packaging process.
  • process-inherent organization elements is shown in the further processing of a flow pack output from chocolate bars.
  • the invention is in no way limited to the type of the packaged goods, it can be any coherent packaging strand with portioned products.
  • Figure 1 shows the last stages of a material flow in a manufacturing process, and that from the portioning of a base (chocolate) and the associated Division into simultaneous production lines.
  • This parallel guidance begins with the table systems 1A to 1D, which take up a doughy material flow of, for example, 22.5 t / h and process it into certain portions.
  • Each board system works on a packaging system, designated 3A to 3D, wherein each of the packaging systems shown can comprise several packaging lines operating in parallel.
  • the product is encased in the packaging lines using the flow pack process, a kind of tubular bag packaging, at a high processing speed.
  • the packaging speed in a packaging line and thus its output is typically 1.0 ⁇ to 1.5 m / s.
  • the product streams 4A / a to 4D / d at the exit of the packaging units should now show the following.
  • a smaller product stream 4a is, for example, fed to an automatic large package 9 at full ejection speed; for some reason, a larger product stream 4A cannot be automatically packaged immediately and should therefore be put into intermediate storage for a later packaging appointment.
  • FIGS. 2a / b show a typical tubular bag packaging with individual portions 20 ⁇ A to 20 ⁇ E 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 21D etc.
  • a cutting device controlled at process speed separates the flow pack assembly 22 from the portions approximately in the middle in the closure zones. This separation of the portions has long been considered indispensable, since the continuous flow pack network (material flow) could not be mastered at an ejection speed of 1 to 1.5 m / s.
  • FIG. 3 shows a schematically illustrated lifting and lowering winding plate drive 40 ⁇ , in which the plates can be inserted or clamped vertically from below or from above for loading.
  • the fully wound winding plates 30 ⁇ A to 30 ⁇ F released by the winding drive 40 ⁇ can be stacked to form a storage tower 45 which, when placed on a standard pallet, can be manipulated with the usual means of transport.
  • the flowpack assembly is wound up in great lengths and the individual windings or coils are stacked on their winding plates. In this way, a very space-tight form of storage of uncommon products can be achieved.
  • the product form is essentially the same as that which is present in the production process, so that the process can be resumed at any time in the intermediate phase of the process phase in which it was left (interrupted).
  • the plate drive 40 ⁇ is arranged like the fork of a forklift lift and lower (arrow B). It is driven, for example, by an electric motor 44 with a pinion 42 via an internal ring gear 43. Below its inner recess is a storage tower 45 with fully wound winding plates 30pulA to 30 ⁇ F.
  • the winding plate drive 40 ⁇ has been raised slightly above the finished (top) flow pack winding in order to insert an empty winding plate 30 ⁇ into the drive from above. After clamping the im Left left (arrow C), the packaging strand 22 runs in at an angle and the plate 30 ⁇ is set in rotation for winding.
  • the winding plate remains "clamped” in the winding plate drive and as soon as it is fully wound, it is placed on the previous, fully loaded winding plate of the storage tower 45. Double arrow B) that it can be pivoted away over the storage tower 45, or the storage tower can be moved away below it. Then the winding plate drive is lowered until it is ready to fill a new storage tower again.
  • the winding plate drive 40 ⁇ sets the winding plate 30 ⁇ in a rotating movement, as a result of which a supplied flowpack strand is wound up successively.
  • the proportion is recorded accordingly in favor of a simple and understandable representation.
  • the winding plates 30 ⁇ shown here can have a side length of approximately 2 to 3 meters, but the stack supports 38 are only 15 cm high. Also not shown are measures to produce the necessary strength of the plate, such as struts, stiffeners, etc., to make them suitable for a load capacity of 20 ⁇ 0 ⁇ to 30 ⁇ 0 ⁇ kg palletized material. A device for threading the packaging strand will be described in detail at a later point.
  • the manufacturing effort per plate should be as low as possible, that is to say that a winding system should have as many functions as possible directly on the winding plate drive 40 ⁇ , the winding plates 30 ⁇ themselves only include the elements necessary for loading, unloading and storage . All other functions are to be assigned to the central winding plate drive 40 ⁇ be, which only has to be available in very small numbers compared to the large number of winding plates.
  • FIG. 4 now shows in concrete form a system for winding or unwinding a flow pack assembly 22.
  • a number of winding plates 50 ⁇ are stacked on standard pallets 32 on each lifting platform 31 shown here.
