WERKSTUECK-FOERDEREINRICHTUNG FUER PRESSEN

摘要

A device for conveying materials, particularly between presses. A moving member is mounted to a main body for horizontal reciprocal movement. A crank shaft is rotatably mounted to the moving member for horizontal movement therewith. A feed bar is supported for sliding horizontal movement by a feed bar guide which is connected to the crank shaft by a connecting rod. Holding members such as vacuum cups are mounted to opposite ends of the feed bar for holding the materials to be conveyed. A belt having a horizontally extending upper portion is carried by a pair of pulleys for reciprocal movement about the pulleys. A revolving member is mounted on the crank shaft and coupled with the upper portion of the belt so as to moved horizontally between the pulleys and revolve at each pulley a pre-set angle about each pulley in response to reciprocal movement of the belt. Revolution of the revolving member rotates the crank shaft so as to vertically move the connecting rod, the feed bar guide and the feed bar so that the feed bar move in vertical and horizontal directions when the belt is reciprocated.
