Abstract

There is shown and described a screw feeder for providing correctly placed screws to a computer-controlled robotic manipulator. Refer now to the figure for a description of the feeder apparatus 2, which includes a shuttle block 4 adapted to receive two screws. Feeder apparatus 2 is at least as high as the screws being fed are long. Shuttle block 4 is operatively connected through opening 16 to a digital output controlled device (not shown) which may be an air cylinder or solenoid. Feeder apparatus 2 is connected to input tube 10. Screws enter tube 10 from a vibratory feeder (not shown). Once a screw 8 is received as shown in shuttle block 4, the mover device urges block 4 toward, in this case, output tube 12. Air enters through opening 16 passing through feeder 2 to force the screw into tube 12.

Forced Air Screw Feed

There is shown and described a screw feeder for providing correctly placed screws to a computer-controlled robotic manipulator. Refer now to the figure for a description of the feeder apparatus 2, which includes a shuttle block 4 adapted to receive two screws. Feeder apparatus 2 is at least as high as the screws being fed are long. Shuttle block 4 is operatively connected through opening 16 to a digital output controlled device (not shown) which may be an air cylinder or solenoid. Feeder apparatus 2 is connected to input tube 10. Screws enter tube 10 from a vibratory feeder (not shown). Once a screw 8 is received as shown in shuttle block 4, the mover device urges block 4 toward, in this case, output tube
12. Air enters through opening 16 passing through feeder 2 to force the screw into tube 12. When the mover device pushes screw shuttle leftwardly, the now empty portion of the shuttle is positioned to receive a new screw 8. The screw now positioned under tube 14 is caused to enter tube 14 by air flow through opening 18. Such action continues. Tubes 12 and 14 terminate at the the article positioned to receive the screws. This feeding technique is quite flexible and provides for forced feeding of many screw types in single or multiple positions. The positions to which screws are blown through tubes 12 and 14 may be fixed, as illustrated, or the tubes may be carried by the robotic manipulator. Further, tubes 12 and 14 could be attached to the...
