Parts unloader for top delivery dies

摘要

A portable and easily adjustable parts unloader which is usable with different types and sizes of power presses is provided by driving a parts remover tray through a simple cable and sheave arrangement and by mounting the parts remover on top of a telescopic post whose effective length is varied hydraulically so the height of the loader is easily changed for different presses. The post, in turn, is mounted on a wheeled cart so it is easily moved from one press to the other by a single operator. By using a simple pulley, the stroke of the parts remover tray is directly proportional to the stroke of the press ram, but the stroke of the tray can be made greater than and/or faster than the stroke of the ram by using a compound pulley in which the two pulley parts have different effective diameters.
