Method for supplying a riveting machine with rivet elements

1. A method for supplying a riveting machine with rivet elements,

wherein at least one rivet element providing arrangement comprising at least one rivet element providing unit for providing and separating the rivet elements is provided,

wherein the riveting machine has a rivet element receiving arrangement comprising at least one rivet element receptacle for directly receiving the rivet elements,

wherein at least a part of the transport from one of the rivet element providing units to one of the rivet element receptacles is realized in a robot-based manner,

wherein the riveting machine has an adjusting unit having an end effector with a riveting tool and the riveting tool sets the rivet element and wherein the rivet elements are transported from the rivet element receiving arrangement to the end effector on a transport path, wherein the transport path is at least partially tube-bound.

2. The method as claimed in claim 1 , wherein the rivet elements are transported from one of the rivet element providing units to one of the rivet element receptacles by a robot having at least two or at least three axes.

3. The method as claimed in claim 1 , wherein the end effector has a drilling tool and a riveting tool, and the drilling tool drills a hole into a structural component and the riveting tool sets a rivet element into the drilled hole.

4. The method as claimed in claim 1 , wherein the rivet element providing unit has a spiral conveyor, by which the rivet elements are fed to a pick-off region, wherein the spiral conveyor has a spiral and a longitudinal axis, about which the spiral extends.

5. The method as claimed in claim 1 , wherein the rivet elements in the rivet element providing unit are separated and fed to a pick-off region.

6. The method as claimed in claim 1 , wherein the supplying of a riveting machine with rivet elements is controlled by a control system, wherein the control system, by a sensor arrangement, detects the rivet elements, wherein the control system, by an optical sensor, detects the position and/or alignment of the rivet elements in one of the rivet element providing units.

7. The method as claimed in claim 6 , wherein the control system, by the sensor arrangement detects the type of a rivet element provided by the rivet element providing unit, wherein the control system checks whether the detected type is constituted by a desired type to be fed to one of the rivet element receptacles.

8. The method as claimed in claim 1 , wherein predetermined characteristics, relevant to a drilling process and/or a riveting process, of the rivet elements are detected prior to feeding to the rivet element receiving arrangement.

9. The method as claimed in claim 8 , wherein one of the characteristics relevant to the drilling process and/or the riveting process, is the rivet length and/or the shank diameter and/or the shank length.

10. The method as claimed in claim 6 , wherein the control system, by the sensor arrangement checks the rivet elements for damage.

11. The method as claimed in claim 4 , wherein a chute is provided, over which the rivet elements slide to the pick-off region, wherein, by a rotation of the spiral, a rivet element is fed, by discharging of this same and sliding over the chute, from the spiral conveyor to the pick-off region.

12. The method as claimed in claim 1 , wherein the at least one rivet element providing arrangement comprises at least two rivet element providing units for providing and separating the rivet elements.
