Abstract
A mold handling system for transferring molds from multiple feed lines to a single main conveyor. The present invention provides an improved and simplified system for transferring molds from several mold making machines to a single conveyor leading to a pouring station. Through the use of a transfer conveyor with cantilevered arms which intersect with the feed lines and the main line, molds can be transferred from the transfer conveyor to the main line by raising and lowering the cantilevered arms. A simplified mechanism for raising and lowering the transfer conveyor is provided in the form of an air actuated bellows apparatus. In order to provide lateral support to the transfer conveyor, brackets flank the bellows that are provided with a predetermined amount of lateral play to provide both the lateral support to the transfer conveyor, as well as enable the transfer conveyor to be raised and lowered.
