Automatically and semiautomatically unjamming nail selection device, designed particularly for machines riveting footwear heel seats onto corresponding heels

摘要: An automatically and semiautomatically unjamming nail selection device, designed particularly for machines riveting footwear heel seats onto corresponding heels. The device has a tank or magazine coupled with rotary chamber equipped units to lift the nails drop them chute having number of raceways which join guides leading mobile combshaped selector moving to-and-fro in perpendicular direction relative feed direction. is select such deliver distributor parallel feeding ducts utilization outlet. integral an arm controlled by first fluid dynamic actuator determines its elastic motion, connected--through rigid coupling--to another is, turn, shifted elastically further actuator. interlocked automatic pilot system, produce some slight oscillation whenever same jams up, system semiautomatic selector, this second controlling selector's motion back resting position jamming not cleared device.
