METHOD AND APPARATUS FOR SEPARATING A COLLATION FROM A SUPPLY STACK

摘要

The present invention is directed to an apparatus and method for separatin g an entire collation of individual sheets from a supply stack for downstream processing. The apparatus generally includes a supply stack tray for containing the supply stack while the collations in the supply stack are being separated; a separator device positioned adjacent to the supply stack tray for separating a corner of each sheet of the collation from the supply stack; a deflector positioned adjacen t to an edge of the collation for deflecting the collation from the supply stack aft er the collation has been separated by the separator; and a gripper device position ed in a plane proximate to the first sheet in the collation for gripping the entire collation after the collation has been deflected from the supply stack and for moving the entire collation downstream for processing. The method for separating a collation o f individual sheets from a supply stack includes the steps of separating a corner of each of the individual sheets in the collation from the supply stack; deflecting the collation from the supply stack; and gripping the entire collation and movin g the entire collation from the supply stack for downstream processing.
