ABSTRACT:
The conveyor system is comprised of a plurality of spools connected by chains at each end of the spool. The space between an adjacent pair of spools defines a pocket. An ejector is carried by the chain within each pocket to eject fruit from the pocket. The ejectors are selectively activated by solenoids lying underneath the chain and mounted on a conveyor channel across which the chain and spools are pulled. A photooptical detector is provided for detecting when an ejector is missing due to damage or other loss. A system control circuit detects the missing ejector and stops the conveyor at a predetermined position so that the missing ejector stops at a predetermined repair location on the conveyor system.
