Device for preventing reverse run of carrier of trolley conveyor

摘要

A reverse run prevention device is provided for use in a trolley conveyor having carriers adapted to run and stop on a rail via engagement and disengagement with pusher dogs on a drive chain. The reverse run prevention device includes an over-running clutch built in a running roller of each carrier to prevent reverse run of the carrier. The overrunning clutch prevents the running roller from rotating via reverse direction where a succeeding carrier is released from the drive chain following its coming into contact with a preceding carrier while the motion of the carriers is being stopped.
