Abstract
A method of transferring an article carried by a first moving conveyor to a second moving conveyor and apparatus for effecting the same. The transfer is effected by a pickup device lifting the article from the first conveyor, transporting it to adjacent the second conveyor, and permitting the second conveyor to receive the transported article for further conveying thereof by the second conveyor. The article may be suspended from a hanger removably supported on a hook of the first conveyor. A sensor is provided for sensing proximity of the hanger to the pickup device for controlling initiation of the raising of the hanger from the hook to pick up the article and free it from the hook for delivery of the lifted article to the second conveyor. Upon delivery of the article to the second conveyor, the transfer is sensed by the proximity sensor when the hanger is removed from the pickup device and in response thereto, the transferring apparatus is returned to a start position for effecting transfer of a subsequent article from the first conveyor to the second conveyor.
