Loading and unloading device for a workpiece

摘要

A device for loading and unloading workpieces comprises a downwardly extending magazine chute at the lower end of which there is a first workpiece carrier which reciprocates in a direction transverse to the magazine chute. The first workpiece carrier receives a workpiece from the magazine chute and delivers it to a second workpiece carrier which reciprocates in a direction parallel to the magazine chute. The second workpiece carrier then transfers the workpiece to the working location of a machine where the workpiece is located and machined while still being held by the second workpiece carrier. After completion of the machining operation the second workpiece carrier returns to its initial position whereupon the workpiece drops down through an unloading chute. The first workpiece carrier engages one portion of the workpiece while the second workpiece carrier engages another portion of the workpiece so that the two workpiece carriers do not interfere with one another.
