Device and method for depalleting and palletizing

摘要

The invention relates to a device and a method for loading and unloading pallets, consisting of a lifting frame (1), which contains lifting forks (11) with a lifting fork drive (12) and other components of the pallet unloading device. A horizontal traversing device (4) and a lifting device (5), which allows the positioning of the lifting frame (1) above a pallet (2) that is to be loaded or unloaded are fitted to the lifting frame (1), said frame (1) having a symmetrical plane which, when in operation, coincides exactly with the symmetrical plane of the pallet (2) to be loaded or unloaded. The invention seeks to enable loading or unloading individual or multiple layers of cardboard trays stacked on top of each other in positive fit, open at the top and arranged according to a stacking pattern. This is achieved by fitting pressure pillows (6), on both sides of the symmetrical plane provided with a friction lining (7) on their free outer surfaces and with moveable, vertical, adjustment plates (8) on the front face, and moveable, vertical, adjustment plates (9) on the longitudinal side.
