Abstract

Rivets are delivered from a feed chute to a transfer location and blown through a feed tube to a loading device. The presence of a rivet is sensed both at the transfer location and at the loading device and a fault indicator is operated in the event a rivet sensed and transported from the transfer location does not wind up in the loading device. The operator hits the reset button which blows clean air thru the feed tube in an attempt to free the jammed rivet. In the event this does not occur, the system assumes the operator cleared the jam and loads the next rivet into position to be transferred and continues the cycle.
