DE2739831A1 - Layer stacking machine - has transfer table sliding right out from under clamps to form layer centring device - Google Patents

Abstract

The stacking machine assembles stacks comprising layers of different sorts, having a layer transfer table sliding into line with a second table on which layers are lying ready. It deposits the layer on the stack by sliding out sideways, the layer being held by clamps during the operation. The transfer table (10) slides all the way out to the side from under the stationary clamps (34-36) and the layer, and the clamps form a centring device preventing the layer tilting or slipping sideways as it is deposited on the stack. Table and centring device are adjustable for height.

The invention relates to a layer stacker for multi-type mixed operations with a layer transfer table, which is used for loading with a uniform type layer lying ready on a layer allocation table through over push into a position in the extension of the layer allocation table and, 'from there to transfer the layer by lowering it to the side cleared layer transfer table on the stack of a predeterminable, jj of several lined up stacks assigned to the individual varieties burst and can be moved back and with essentially sideways | holding stamps that can be attached and removed from the layer to be transferred for, Holding the layer above the stack when clearing the layer transfer table.

In a known layer stacker of this type, the layer transfer table is along a rail guide over the stacking areas back and forth | sliding out. A lifting platform is provided for each individual stacking location, with which the stack that has started on it, depending on the '|

sufficient stack height is raised so far that the top f;>, Position on a certain, for the handover of the next position for all | Stacking locations fixed uniform height device. This well-known | j Layer stacker requires considerable effort due to the many! independently of each other adjustable lifting platforms. |]

The object of the invention is to provide a layer stacker of the type initially mentioned to design the named type in such a way that the layers can be dispensed on the different height levels of the topmost layer that arise as the stack grows. ff

The invention is characterized in that the layer transfer table under the stationary holding stamps and the ready-held position can be completely withdrawn to the side, and that the holding stamps form a centering device which closely surrounds the ready-held position with a tolerance distance and with which the ready-held position when the position transfer table is withdrawn and when it falls onto the stack, it remains centered against lateral slipping and tilting and that the height of the layer transfer table can be adjusted with the centering device.

According to the invention, the required height compensation is through the Height adjustability of the layer transfer table and the centering device achieved. The devices for this height adjustment must *! be provided only once according to the invention, even if ' a lot of stacking spaces should be served. This leads to a considerable simplification of the device, especially if much many stacking locations are served. The intended height adjustment of the layer transfer table also allows it without additional effort to compensate for a difference in level between the layer allotment table and the stacking positions, so that the layer allotment table can be arranged in a level as it is most expedient for loading with the preceding conveyors. In which The known layer stacker described at the outset, the layer allocation table must be arranged at the level on which the layer transfer table is located moves, so that one additional means to compensate for a difference in level to preceding conveyors this must provide level differences, which are dispensable according to the invention.

A preferred embodiment of the invention is characterized by a chassis for the layer transfer table and the centering device which can be moved back and forth on a straight first rail guide laid along a number of stacking locations and by a • The stacking areas of this row with the highest possible stack, which is mounted on the chassis and towers above the stack, on the one transverse to the first rail guide directed second rail guide is laid for a trolley, on which the layer transfer table is attached stiffened is.

With such a configuration, a row of stacks can be served whereby the layer transfer table can be located within this row or opposite it on the other side of the rail guide

A preferred development of the invention, which makes it possible to serve two rows of stacking locations with relatively little additional effort, is characterized in that the stage with the second rail guide over the stacking locations of a second row of stacking locations, which opposite the first row along the first Rail guide is lined up »extends ·

The layer stacker 24 consists of a chassis 19 which runs along the first double track laid on a bridge structure 11 gene slide guide 12 can move back and forth along the two parallel rows 13, 14 I lined up stacking locations. On the chassis 19 is a platform 16 in the manner of an elevator in the direction || of the double arrow 17 along the vertical rail guide 18 up || and movable. The stage 16 extends over the two tire d hen 13 and 14 and has two horizontal, transversely jfj the rail guide 12 extending, arranged above one another Schienenführun- | gen 20 and 21 for two trolleys 22, 23. The trolley 23 P contains the layer transfer table 10 and on the trolley 22 is one
Centering device formed from movable holding punches 34 to 37 is supported. ■■;

the position is just above the stacking position 15. Now -dl * =: trolley 23 moves to the side in the direction of arrow 39 and pulls the layer transfer table 10 slidingly to the side under the layer aligned between the holding punches 34, 35 »36, 37. The layer can now fall onto the stack below. In order to keep the height of fall extremely low, the layer transfer table is brought very close to the respective stacking level reached in the relevant stacking position, in this case the stacking position 15. The holding stamps act when pushing away the Lagenübergabetisehes and also when falling down as a position centering device and keep the position centered so that it is centered on the stacking position or on the layer already stacked there. As can also be seen in part from FIG. 3, the trolley 23 does not have any parts protruding over the table surface of the layer transfer table 10 which could hinder the lateral displacement in the direction of arrow 39 and in the opposite direction. The Lauikatze 23 finds space with the layer transfer table above the free central aisle 40 between the two rows 13 and 14. The trolley 22 is loaded is still found on the stacking position 15. The holding stamp of this trolley now give the remote location free -and the stage 16 moves m ¹ two trolleys on the rail guide 18 upwards. The trolleys move back along the stage to the starting position shown in the upper left corner of FIG. The chassis 19 moves across the street to the layer allocation table 4 or 8, depending on which layer allocation table the next layer is to be removed from. The device is now ready to take over the next layer from the layer allocation table in question and then to bring it to any of the intended stacking positions of the two rows 13 and 14.

In the drawing, a second layer stacker 41 is also provided is designed in exactly the same way as the layer stacker 24 and can be operated with it at the same time. At every stacking position, for example the stacking position 15, there is a roller conveyor conveyor section with conveying direction in the direction of arrow 39 or in the opposite direction. The stacking positions are loaded with pallets from an F lettenvörrät 42, of which the pallets one after the other on one Pallet runway 43 arrive. The last section 44 of this pallet runway 43 .is along a rail guide 45 which is in the aisle 40 is laid, movable and can be brought into positions in extensions to the individual stacking positions. The ones on the section 44 lying pallet can be moved from there to one of the opposite stacking positions.
