Abstract

A palleting device for palleting stacks of flat objects on a height-adjustable pallet includes a moving support device located above the pallet. The stacks are delivered onto the moving support device by a supply conveyor and into formation on the pallet or on a pallet stack forming on the pallet. The layer to be stacked is ejected from the support surface by a release motion of the support device while retaining the stacking pattern of the stack. In order to be able to place the palleted stack onto the support device so that it is lined up edge-to-edge, the supply conveyor is formed from two conveyor belts which are separately controllable and positioned in alignment with each other in a common plane parallel to the support device. The front delivery rollers of the belts can be moved in both the same and opposite directions by movement of lower conveyor belt strands.

Claims

1. A palleting device for palleting stacks of flat objects with a pallet having an adjustable height comprising:

a supply conveyor for supplying said stacks of flat objects,

a moving support device, located above the pallet, onto which the stacks are delivered from said supply conveyor in formation on the pallet and from which a stack is ejected by a release motion of the moving support device while retaining a stacking pattern of the stack, the supply conveyor including two conveyor belts which are separately controllable and aligned with each other in a common plane parallel to the moving support device, and

front delivery rollers for said two conveyor belts which are movable in both the same and opposite directions due to movement of lower conveyor belt strands.

2. A palleting device according to claim 1, wherein the moving support device is formed by conveyor belts and widths of the conveyor belts of the support device correspond to a width of the pallet.

3. A palleting device according to claim 1, and further comprising an outlet conveyor of smaller width than said supply conveyor that can be moved in a transverse direction adjoining said supply conveyor.

4. A palleting device according to claim 1, wherein the moving support device includes two conveyor belts aligned in a common plane, and further comprising mutually facing eject rollers for said two conveyor belts which can move opposite to each other by movement of lower conveyor belt strands.
