ABSTRACT:
In one embodiment, a conveyor system includes a conveyor belt having a plurality of conveyor belt rollers configured to divert articles on the conveyor belt, and a drive mechanism that engages the conveyor belt rollers, the drive mechanism being configured to drive the conveyor belt rollers, the drive mechanism being adjustable such that the conveyor belt rollers can be selectively driven in a first angular direction and, optionally, a second, opposite angular direction so that articles can be selectively diverted to either side of the conveyor belt at a desired diverting angle. One version of the drive mechanism has drive rollers mounted in cartridges and rack gears engaging pinion gears on the cartridges to adjust the orientation of the drive rollers relative to the belt rollers to drive them in selectively opposite angular directions. Such a conveyor system with a series of sequential roller actuation zones driven by separately actuated drive mechanisms is arranged diagonally to an infeed conveyor and a multi-lane outbound conveyor to realize a switch conveyor.
