ABSTRACT:
A device (10) is disclosed including a discharge unit (54) having a vertical conveyor (56) formed by a pair of vertically arranged belts (58) each including circumferentially spaced shelves (60) defining a plurality of evenly spaced flights. A diverting conveyor (16) is pivotally mounted about its infeed end so that its outfeed end can be moved to be synchronous with one of the flights of the discharge unit (54) or to an overflow position. In particular, a servo motor (50) pivots the diverting conveyor (16) under the control of a controller (74) depending upon whether product is detected by a sensor (52) in the diverting conveyor (16), upon the rate that the flights of the discharge unit (54) are moving, and upon the pivotal position of the diverting conveyor (16). The device (10) is then able to place products which are fed to the diverting conveyor (16) with random spacing into the flights without bumping or bunching the products together.
