ABSTRACT:
An article sorting conveyor includes an endless flexible carrier having a series of longitudinally spaced cross slats or tubes supporting article transfer pushers for lateral movement on the carrier relative to the direction of movement of the carrier. Each pusher has a vertically movable shaft which carries a follower or roller for selectively engaging an upper linear track or a lower curved or diverting track. Each shaft is releasably retained in an upper retracted position where the corresponding roller engages the upper track and is spring biased to a lower extended position where the roller engages the lower track. A controllable actuator is positioned ahead of each diverting station along the conveyor to release a series of selected shafts and rollers, and an inclined ramp at the end of the conveyor successively shifts the shafts and rollers from their lower extended positions back to their upper retracted positions.
