Privilege claimed - Begärd priority (73) Elevator GmbH, Poststrasse 9, CH-6300 Zug, Switzerland-Switzerland (CH) (72) Pekka Kuuhari, Vantaa, Frans Vainio, Helsinki, Finland-Finland (FI) (TM Oy Heinänen Ab ( M) A method and apparatus for unloading and collecting beverage baskets in a stack - The present invention relates to a method for unloading beverage baskets or other similar packages in a stack each has the same product, as opposed to beverage baskets comprising different products.

In large warehouses, such as central warehouses in wholesalers, incoming products are sorted for further shipment to smaller units. According to a known method, the pallets, each of which contains similar products, are placed side by side on a kind of track. When products are formed into so-called mixed pallets, on which product packages are collected from different pallets, a collecting device moves between the pallets, which lifts the necessary product packages from one pallet to a mixed pallet formed at a time. The disadvantage of this method is the large need for space. The pallets take up too much space. In addition, due to the high need for space, the collection journey is often 5,831 4 long. This causes a lot of unnecessary travel between different parts of the warehouse and results in poor capacity of the method. In addition, the method is very difficult to automate.

According to another known method, the pallets are unpacked into packing queues on long lines from which the packs are collected separately to form a new pallet. The disadvantage of this method is that too much time is spent only dismantling the pallets and re-stacking. This use of time is usually completely useless, as experience has shown that $ 70-90> of products can be transferred in stacks or layers directly to a pallet formed from a pallet and only $ 10-30 of products need to be sorted and re-assembled, i.e. unpacked into separate packages. In addition, the method has the disadvantage of a large space requirement, since single-layer packaging rows require a large total length of tracks. It is clear that the equipment according to this method does not achieve the best possible capacity.

The object of the present invention is to eliminate the above-mentioned drawbacks and to provide a method which is substantially more efficient in capacity than known methods. The method according to the invention is characterized in that the contents of each transport pallet are unloaded into beverage basket stacks which are temporarily stored on stacking tracks and which are separately stacked on re-palletized transport pallets or if necessary

The method according to the invention is based on the fact that the incoming pallets are unloaded in stacks and the stacks are passed, each product grade on its own lines, to await re-palletization. In addition, some of the stacks are reserved for unloading into individual beverage baskets. Stacking can be done one at a time as needed or all at once in box queues to wait for stacking and stacking. In connection with re-opening, the necessary beverage baskets are taken from the stack tracks and, if necessary, individual beverage baskets are taken. Since several beverage baskets can be taken in stacks at the same time and, if necessary, individual baskets can also be taken flexibly, unnecessary unloading and reloading can be avoided, and it is clear that a very high capacity is achieved by doing so.

A preferred embodiment of the invention is characterized in that the beverage basket stacks, on the one hand,> the individual beverage baskets, on the other hand, are transferred from the stack paths to the collection paths, whereby independent collection of whole drinking stacks and individual beverage baskets is possible. Simultaneous, flexible operation results in high capacity.

The invention also relates to an apparatus for carrying out the method, the apparatus comprising an inlet conveyor track for transport pallets loaded with stacked beverage baskets or the like, a pallet unloading device, a beverage basket stack distribution track, a stack picking track The apparatus according to the invention is characterized in that stack tracks for intermediate storage of beverage basket stacks are connected to the distribution path of the apparatus, the stacking ends of which have stack discharge devices for transferring the beverage baskets one by one to the beverage basket collecting path. With the apparatus according to the invention, a transport pallet stacked with the desired products is obtained simply and quickly from the warehouse to the exit.

The invention will now be described, by way of example, with reference to the accompanying drawings, in which

Figure 1 shows a top view of the apparatus according to the invention.

Figure 2 shows a section taken along the line II-II in Figure 1.

Figures 3 and 4 show the stack unloading device in more detail in different positions.

Fig. 5 shows a section taken along the line V-V in Fig. 3.

Fig. 6 shows a section taken along the line VI-VI in Fig. 4.

Pallets 2 containing beverage baskets are brought along the inlet conveyor path 1 to the pallet unloading device 3 · Each pallet 2 contains only one type of product, but different pallets may contain different product grades. In the unloading device 3, the stacked beverage baskets are separated into stacks which run along the distribution path 4, each quality to its own intermediate storage paths 5, hereinafter referred to as stack paths. At the same time, the pallets on which the product baskets were imported travel empty to the discharge conveyor track 25 to await reloading 10. Of the stacking tracks - 58314 5, the product unloading equipment for each product grade is replenished so that two basket stacks are always waiting to be unloaded into individual baskets. The replenishment takes place by a lifting device 16 which moves perpendicularly between the stack track 5 and the stack unloading device 9 on rails 15 · In addition, the lifting device 16 moves parallel to the stack track 5 on the body 17 and rotates about its axis 18.

Figure 2 shows the basket collection phase in operation. In it, the basket stacks 13 of one product are on the stack path 5. The stack shifter 20 is just moving the basket stack 14 to the stack picking path 6. 6 so that the first stack comes on top of the transfer device 20.

If the desired product quality is required in an amount that does not correspond to the quantity obtained from the whole basket stacks, individual baskets are required. The required individual baskets 24 are taken at the same time as the collection of the basket stacks to the stack unloading device 9. The stack unloading device 9 enables the collection of the individual baskets. The stack unloading device 9 has a lifting device 21 which lifts the basket stack off the top of the lowest basket 24. When the lifting device 21 has raised the basket stacks sufficiently, the intermediate member 22 engages the basket transfer device 23, which transfers the basket 24 to the collecting track 7. Each product-specific stacking path 5 and stacking device 9 have similar devices described above, except multiple parallel tracks 5.9. The basket stacks pass along the collecting tracks 6 to the palletizing device 10 and the individual baskets travel along the basket collecting track 7 first to the stacking device 11 where they are stacked into stacks the height of the original stacks, thus containing different products, and further to the palletizing device 10. In the palletizing device 10 from the unloading device 3 of the incoming conveyor track 1. The formed mixed pallets 12, which now comprise the desired quantities of baskets containing different products, travel along the discharge conveyor track 25 for further dispatch.

It will be apparent to those skilled in the art that various embodiments of the invention may vary within the scope of the claims set forth below. Thus, the number of stacking tracks 5, stacking devices 9, conveyor or collecting tracks 1,4,6,7,25 or other devices is not limited to the number according to the example, and the placement of different parts of the equipment is not fixed but varies according to the circumstances, provided that the overall operation is not suffered from it. Likewise, the lifting device 16 can be replaced by other arrangements.
