Abstract: The system accordingly strictly accounts for all rivets and prevents a rivet from being removed for any reason and not accounted for. This assures that no free rivet will find itself within the workpiece being riveted.

Abstract: Automatic riveting machine wherein spent mandrels generated by the setting of rivets pass through a collection tube en route to a collection box, having first means for sensing tool operation, second means for sensing entry of spent mandrel into collection tube, third means for sensing departure of spent mandrel from collection tube and means for determining from operation of said first means and of said second means and non-operation of said third means that a spent mandrel is blocked in collection tube and operating identification means to indicate said blockage.

Abstract: A system for first setting a blind rivet and then verifying the correctness of the set comprising a rivet setting tool to set the rivet and computer logic to verify the correctness of the set. The setting tool includes a jaw assembly for holding the stem of the rivet's mandrel fitted to an axially movable pulling shaft. Both the pulling force of the setting tool and the displacement of the pulling shaft are measured and the measurements are interpreted by an integrator to determine the total energy of the setting process. The determined total energy is then compared with an ideal total energy to assess whether or not the set of the particular rivet is acceptable. Other quantitative comparisons may be made against other ideal values.

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.
