Abstract
An overhead conveyor system with rolling conveyor carriages guided on rails. The pushers provided for moving the conveyor carriages out of the main track and onto a secondary track are provided with a claw which can be swung in a direction opposite to the direction of transport (T) into an upward-swung third position. In this position, a conveyor carriage which is blocked in the region of a switch and cannot be moved out of the track can be passed by the pusher without damage to the conveyor carriages or the overhead conveyor system. When the claw is swung upward, a flap is at the same time moved out laterally, which can serve as a signal for immediately stopping the conveyor system. The outwardly swung flap may assist maintenance personnel in finding the switch at which a conveyor carriage cannot be properly moved out of the line. The pusher includes a recess which is covered by a spring-loaded plate. The claw is fastened asymmetrically in the pusher so that it swings upward into the recess. The claw is urged into its lowest position by a spring above the plate. A force acting on the claw and swinging it into its third position causes the claw to move against the plate as the force becomes larger than the effective force of the spring.
