  • Endless belt coveyor unit for a stamping press
    Patent number: 6186318
    Abstract: An elongated low profile sheet metal tray has a bottom panel adapted to seat on the bolster plate of a stamping press under a die set. The panel supports adjacent upper and lower runs of an endless belt directed around guide rollers and a drive roller supported by cast support members removably connected to opposite ends of the tray. A motor and gear reducer unit is mounted on one support member and drives the belt drive roller, and the sheet metal tray has opposite integral side rails forming inclined surfaces and channel portions enclosing opposite edge portions of the belt. A sheet of plastics material extends between the bottom panel and the bottom run of the belt, and a detector senses belt stoppage for stopping the motor and stamping press.
