APPARATUS FOR AUTOMATIC PILE CHANGING AT THE DELIVERY OF A PRINTING PRESS PARTICULARLY A SHEET-FED ROTARY PRINTING PRESS

摘要

The apparatus has an auxiliary stacking device (16), in order to separate the already stacked sheets from the sheets still to be deposited. The auxiliary stacking device (16) is rapidly introduced into the stack space (13) as soon as the stack (1) in the delivery (2) actuates an electrical switching element (12). At the same time, the full stack (1) is moved out of the stack space (13) by means of a pallet carriage (3). When moving out the stack, a conveying device (7) is switched to operational readiness by means of a switching contact (15) and moves an empty pallet (5) out of a pallet magazine (6) to the stack space (13).
