ABSTRACT:
A modular tray accumulator system includes a number of horizontal and vertical stacked conveyors arranged in a portable module. Each conveyor operates independently of the others. The system may be mechanically raised or lowered to any desired height, or may be moved between different floors as a unit. In a first embodiment, each conveyor is activated when a tray is placed on the input end of the conveyor, and moves a preselected distance forward. In a second embodiment, the trays are moved forward by variable friction drive.
