Punch rivet supply device and punch riveting device

A supply device for a joining element, the joining element including a shaft, which extends along a joining element axis and which has a first diameter, and an adjacent head, with a second diameter which is greater than the first diameter;

• wherein the supply device comprises:
• a base which partially defines a first joining element channel, a second joining element channel and a third joining element channel which are at least partially arranged in a common channel plane, and which each joining element channel has a cross-section which is a polygon adapted to the shape of the joining element and includes a head region and a shaft region with the shaft region perpendicular to the head region, and which each joining element channel has an opening, and wherein the first and the second joining element channels are orientated relative to each other at a switching angle which is in a range from 5° to 45°, and wherein the first and the second joining element channels merge into the third joining element channel at a junction;
• and
• a switching arrangement located in the base at the junction.

A joining device for installing a joining element in a workpiece, the joining element including a shaft, which extends along a joining element axis and which has a first diameter, and an adjacent head, with a second diameter which is greater than the first diameter;

• and wherein the joining device comprises:
• a joining head operable for installing the joining element in the workpiece;
• a joining element supply arrangement operable for supplying the joining elements to the joining head, and the joining element supply arrangement includes a supply channel through which joining elements can be transported, and
• a supply device operable for connecting the joining head and the joining element supply arrangement;
• and wherein the supply device includes:
• a base which partially defines a first joining element channel, a second joining element channel and a third joining element channel which are at least partially arranged in a common channel plane, and which each joining element channel has a cross-section which is a polygon adapted to the shape of the joining element and includes a head region and a shaft region with the shaft region perpendicular to the head region, and which each joining element channel has an opening, and wherein the first and the second joining element channels are orientated relative to each other at a switching angle which is in a range from 5° to 45°, and wherein the first and the second joining element channels merge into the third joining element channel at a junction;
• and
• a switching arrangement located in the base at the junction.
