Conveyor transfer method and apparatus

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 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. Upon sensing of the removal of the article, the transferring apparatus is returned to a start position for effecting transfer of a subsequent article from the first conveyor to the second conveyor. The transfer may be interrupted in the event the second conveyor is not in condition to receive the article being transferred, such as where the second conveyor does not have an available space for accommodating the article. Upon sensing of the receiving capability, the article may be brought from the intermediate position to the conveyor for transfer thereto. The conveyors may utilize hooks for suspending the articles being conveyed. Transporting of the article from the first conveyor to the second conveyor may be effected by an arcuate movement about a vertical pivot axis. To assure positive retention of the article by the transferring apparatus, locking structure may be incorporated therein with suitable controls. The transferring apparatus may be fluid operated for improved facilitated positive transfer of the article.
