Abstract
An improved automatic rivet feed apparatus which can be used as a retrofit to an existing power driven riveting tool or incorporated integrally into a riveting tool. A rivet strip holds each of the plurality of rivets at individual fixed positions on the rivet strip. Included is a rivet strip release hook which stops the rivets, as they are advanced one-by-one, at rivet pick-up point and releases each of the rivets from the rivet strip. A hand mounted on the end of a pneumatic ram grips the rivets at the rivet pick-up point, the hand having a biased latch to prevent slippage of the rivets. The pneumatic ram moves the rivet forward and rotates to place the rivet in alignment with the nose piece of the riveting tool. The pneumatic ram then retracts and inserts the mandrel of the rivet into the nose piece and returns to the rivet pick-up point to repeat the steps. A rivet pick-up mechanism is used to hold the rivet as it is released from the rivet strip and moved to the nose piece of the rivet strip.
