Abstract:
Apparatus that receives multiple screws serially from a vibrating bowl with a single exit ramp, collects a plurality, e.g., six, of screws and distributes the plurality of screws simultaneously to different tubes in one assembly. A rotary holder having a plurality of notches for receiving and holding screws, receives the screws serially from a feeder rail coupled to a vibrating screw feed bowl. After the notches have filled with screws, the screws are released into a corresponding plurality of exit tubes, where the screws may be fed (e.g., by air pressure) to a screw applicator device coupled to a distal end of the exit tubes.
