ABSTRACT:
A device for positioning or stopping a workpiece carrier of a conveying device in which workpieces are fed to different work stations following each other in a conveying direction is provided. The workpiece carrier is provided with an external stop projecting therefrom transversely of the conveying direction and arranged to cooperate with a stop carrier element disposed outside the path of movement of the workpiece carrier and having a stop surface moveable into and out of the path of movement of the stop in the conveying direction. In one embodiment the stop carrier element is moveable transversely of the conveying direction and engages a stop below the workpiece carrier. In another embodiment the stop element comprises a rotary cylinder extending longitudinally of the conveying direction and having a generally helical slide track engaging a stop projecting laterally from the workpiece carrier. The slide track comprises alternate sections extending at right angles to the axis of rotation of the cylinder and intermediate sections extending obliquely whereby successive stops are formed by the alternate right angle sections.
