Abstract:

An auxiliary feeder apparatus for a punch press. The feeder picks up blank stock to be punched, transfers it to a work holding collet where the press punches a circular pattern of spaced holes or slots in the blank to form an electric motor lamination or the like. After punching, the feeder apparatus picks up the finished part and transfers it to a storage location while at the same time picking up and transferring a new blank to the collet for punching. The operation of the feeder apparatus is integrated with the operation of the punch press and is fully automatic. Controls in the feeder apparatus and press prevent the punch from operating when malfunctions, such as a part not properly positioned on the collet or two or more parts transferred to the collet, occur.
