ABSTRACT:
A bi-directional stacking conveyor is mounted below the discharge from a main conveyor and lies substantially perpendicular to the main conveyor. An adjustable length backstop and adjustable width guide fingers are carried by the stacking conveyor to accommodate forms of different lengths and widths, the backstop and side guides holding the sheets snugly in the stack. In response to a signal from a controller, the guide fingers on a side of the stack in the direction of desired movement are displaced to an out-of-the-way position and a motor drives the stacking conveyor belt to displace the stack in a first direction. At the end of a job or completion of a count and responsive to a signal to move the stacked sheets in an opposite direction, the controller operates the stepper motor for the opposite fingers to displace those fingers out of the path of movement of the stacked sheets in the opposite direction so that the motor is reversed and the conveyor belts displace the stacked sheets in the opposite direction.
