Abstract
A shuttle type accumulating conveyor adapted to advance articles located behind an empty station to their next successive stations. The conveyor comprises an elongated support along which the stations are longitudinally spaced apart, a transfer bar movable forwardly and rearwardly longitudinally of the elongated support, pusher type feed units and feed unit setting assemblies mounted on the transfer bar and actuator assemblies for moving the feed units to feed positions so that upon an initial rearward movement of the transfer bar from a start position all feed units behind an empty station are moved to their feed positions. The transfer bar is then moved forward a distance substantially greater than the distance between stations to advance articles from station to station. Binding of the drive mechanism due to the prolonged travel of the transfer bar, during which feed unit setting assemblies contact actuator assemblies, is prevented by cooperating recess and pivot means on the actuator assemblies. Knockdown means are provided to move all feed units out of their feed positions before the start of a work cycle.
