STACKER FOR SHEET MATERIALS

摘要

A stacking device for sheet material such as banknotes and receipts has a stacker drum with a suction opening at a predetermined location on the periphery. The suction opening grips the leading edges of the sheets to be stacked at a first tangential position and releases the sheets against a stopper at a second tangential position. The stacker drum has air openings on the periphery behind the suction opening. The air openings discharge pulsating compressed air to separate the portion of the sheets trailing the leading edges from the drum.
