Abstract

A collector and discharge mechanism permits a continuous flow of sheet material into a stacker station while predetermined size batches are removed from the growing stack and discharged for processing and cartoning. The mechanism includes a kick-off assembly for passing sheets into the stacker, a vertically movable support table on which the sheet pile collects in the stack, an interrupter mechanism for projecting a plate piece between successive sheet deliveries into the stacker over the last sheet on top of the batch to be removed, a divider assembly for separating the continually growing stack in the stacker from the top of the batch and separately supporting the stack on spears, an elevator for raising the delivery end of the kick-off assembly while the spears hold the growing stack in the stacker to obviate the risk of sheet delivery jam-ups, and a discharge conveyor for receiving the removed batch from the support table, after which the table returns to the stacker to resume support for the growing stack.
