Patent ID: 8850685

Claim:
A method for delivering and setting rivets, the rivets being delivered to a tool via at least one intermediate buffer for the temporary storage of rivets, the at least one intermediate buffer being mounted on the rivet setting tool and having an outlet that is connectable to the tool, comprising selectively transporting rivets from a reservoir of rivets, individually or in groups, through at least one delivery tube towards the at least one intermediate buffer by using compressed air, moving the at least one delivery tube and/or the at least one intermediate buffer from a position where the tube and intermediate buffer are separated to a position in which they are connected and in which a rivet path between the at least one delivery tube and the at least one intermediate buffer is established, transferring the rivets from the at least one delivery tube into the at least one intermediate buffer by using compressed air, temporarily storing at least some of the rivets in the at least one intermediate buffer, selectively releasing a rivet from an outlet of the at least one buffer and delivering the released rivet to the tool, advancing a punch of the tool to insert the rivet into a workpiece such that the rivet is upset by a rivet upsetting die that is disposed opposite the tool, wherein the at least one delivery tube and at least one intermediate buffer are separated during insertion of the rivet.
