ABSTRACT:
Washers are cascaded downwardly from a vibratory feeder into a reservoir which overlies a rotatable disc having a series of angularly spaced pockets. As the disc rotates, each pocket picks up a washer and carries the washer to an assembly station where a screw blank is telescoped into the washer, the screw blanks being delivered to and being carried by heads spaced angularly around a rotatable turret. A feeler senses the approximate quantity of washers in the reservoir and causes the vibratory feeder to be activated automatically when the supply of washers is low and to be de-activated when the supply is large. An arcuate shoe, an agitator, and a sensor also are provided for camming the washers into position to be received by the pockets, for agitating the washers in the supply, for ejecting excess washers from the pockets, for detecting the absence of washers in the pockets and for ejecting any washers which might not receive screw blanks, respectively.
