Abstract
A workpiece carrier ( ) for conveying one or more workpieces with a belt conveyor ( ) is described, which reduces the production cycle time of an industrial manufacturing plant. The workpiece carrier ( ) includes energy storage devices ( ), into which energy of motion of the workpiece carrier ( ) is transferred when the workpiece carrier is braked against or stopped on the belt conveyor ( ). The energy storage devices each include a coupling element ( ), advantageously a friction wheel or contacting piece , urged into continuous contact with the conveyor belt, and a spring device, advantageously a spiral spring or a coil spring , connected with the friction wheel and put under tension when the workpiece carrier ( ) is braked. If the workpiece carrier is no longer braked or stopped, the spring device is released and delivers stored energy by driving the friction wheel or contacting piece, where by the workpiece carrier ( ) is additionally accelerated.
