ABSTRACT:
A device for stacking sheet material in the form of individual stacks comprises a fixed stop, a vertically movable stop, a support surface, a sensor and a guide member, to which two pushers are fastened, which are activated by lifting cylinders. The sheet material to be stacked is conveyed by conveying rollers and falls down freely between one of the stops and a stop face where the individual stacks are formed. The guide member can be raised and lowered about a pivot by means of a lifting cylinder which engages a pivot point provided at the underside of the guide member. Stacking is performed in individual stacks, whereby two super-imposed individual stacks each are mutually offset in the direction of transport Z by a distance of displacement x.
