<p>In one embodiment, a conveyor system (300) includes a conveyor belt (302) having a plurality of conveyor belt rollers (304) configured to divert objects (o) 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 a second, opposite angular direction so that objects 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 (308) mounted in cartridges (320) and rack gears (342) engaging pinion gears (334) on the cartridges to adjust the orientation of the drive rollers relative to the belt rollers to drive them in selectively opposite angular directions.</p> |
