ABSTRACT:
The method and apparatus (10) for moving and positioning parts (150, 250, 350 or 450) on workpieces (160) is described. The apparatus includes a vibratory bowl (12), a conveyance and feed system and a positioning cylinder (82). The bowl aligns the parts and orients the parts using a gauge (16, 216, 316 or 416). The conveyance and feed system moves the parts through a conduit (34) using an escapement (44) to feed the parts one at a time to the positioning cylinder. The positioning cylinder has a pneumatic piston (90) with a piston rod (100) having an extension (102) and tip (104). An electromagnet (112) is mounted at one end of the positioning cylinder. When activated, the positioning cylinder extends the piston rod such that the tip extends into an opening (150D, 250D, 350D or 450D) in the part. The electromagnet is activated simultaneously and sends a charge down the piston rod which charges the extension which is constructed of a magnetic material. The part is held on the tip by the magnetic attraction to the extension. When the forward movement of the piston rod stops, the forward inertia of the part overcomes the magnetic attraction and moves the part off the tip to the workpiece.
