Abstract

An item accumulator and conveyor for accumulating a row of items and then conveying it off to one side for collection and stacking of the row. A first conveyor brings the items to two other conveyors, or to one conveyor having two sections. One of the two sections supports the items at one elevation and accumulates them in a row, and conveyor supports then permit the first section to lower and thereby transfer the items to the second section at a lower level, and the second section then moves the items off to one side. The two conveyor sections include movable support members and they may be at a declining angle so that the items can move under the force of gravity. A stop member is operatively disposed between the incoming conveyor and the other conveyor, such that when the first section is lowered the stop member is effective to preclude the entry of additional items onto the first section, and there is therefore an interconnected system for actuation of the stop member and the lowering of the one conveyor section in synchronization.
