Abstract

The disclosure relates to a method for filling a rivet cartridge with rivet elements by means of a rivet loading station having a rivet delivery unit for delivering the rivet elements and having a rivet cartridge receiving means for receiving a rivet cartridge, wherein the rivet elements are supplied from the rivet delivery unit to a rivet cartridge which is received in the rivet cartridge receiving means and are received therein in an aligned manner. It is proposed that at least part of the transport from the rivet delivery unit to the rivet cartridge is effected in a robot-based manner.

First claim

The invention claimed is:

1. A method for filling a rivet cartridge with rivet elements using a rivet loading station having a rivet delivery unit for delivering the rivet elements and having a rivet cartridge receiving element for receiving a rivet cartridge,
wherein the rivet elements are supplied from the rivet delivery unit to a rivet cartridge which is received in the rivet cartridge receiving element and are received therein in an aligned manner,
wherein at least part of the transport from the rivet delivery unit to the rivet cartridge is effected in a robot-based manner,
wherein the rivet loading station comprises a control unit for controlling the rivet loading station, wherein the control unit detects a type of rivet element which is delivered by the rivet delivery unit, wherein the control unit controls whether the detected type of rivet element is a required type of rivet element to be filled into the rivet cartridge,
wherein rivet elements of the same type can be supplied to at least two of multiple rivet cartridges, and
wherein the rivet elements are supplied in dependence on a test from a testing unit to the rivet cartridge assigned to a subcategory corresponding to the rivets' categorization into a subcategory.

2. The method as claimed in claim 1 , wherein rivets of a different genus comprising at least one of a different type, a different nominal length and a different nominal diameter, can be supplied to a rivet cartridge or to different rivet cartridges by the rivet loading station without modifying the mechanical configuration of the rivet loading station; and wherein the rivet elements are separated into singles in the rivet delivery unit and supplied to a gripping region.

3. The method as claimed in claim 1 , wherein rivet collars of a different genus comprising at least one of a different type, a different nominal length and a different nominal diameter, can be supplied to a rivet cartridge or to different rivet cartridges by the rivet loading station without modifying the mechanical configuration of the rivet loading station.

4. The method as claimed in claim 1 , wherein rivets and rivet collars can be supplied to a rivet cartridge or to different rivet cartridges by the rivet loading station without modifying the mechanical configuration of the rivet loading station.

5. The method as claimed in claim 1 , wherein the rivet elements are separated into singles in the rivet delivery unit and supplied to a gripping region.

6. The method as claimed in claim 1 , wherein characteristics of the rivet elements that are relevant to a drilling process and/or a riveting process are detected prior to supplying them to the rivet cartridge.

7. The method as claimed in claim 1 , wherein the control unit tests the rivet elements for damage using the optical sensor of the sensor arrangement.

8. The method as claimed in claim 6 , wherein a characteristic that is relevant to the drilling process and/or the riveting process is a rivet length and/or a shank diameter and/or a shank length.

9. The method as claimed in claim 6 , wherein the characteristics of the rivet elements are detected with a testing unit comprising an optical sensor, and wherein a visual axis of the optical sensor directed to the rivet delivery unit and a visual axis of the optical sensor of the testing unit do not extend parallel to one another.

10. The method as claimed in claim 1 , wherein the rivet cartridge receiving element and/or rivet cartridge comprise a pocket into which the rivet elements are deposited.

11. The method as claimed in claim 1 , wherein the rivet elements are conveyed into the rivet cartridge by a pressure difference.

12. A method to produce a structural component,
wherein a rivet cartridge is filled as claimed in claim 1 and wherein the rivet cartridge is then inserted into a rivet storage unit of a production facility for producing a structural component and the production facility drills a hole in a structural component for generating a rivet joint and inserts a rivet element from the rivet cartridge into the hole and rivets.

13. A rivet loading station for carrying out a method as claimed in claim 1 .

14. The method as claimed in claim 5 , wherein the rivet elements are gripped in the gripping region in a robot-based manner.

15. The method as claimed in claim 1 , wherein the control unit detects the position and/or alignment of the rivet elements in the rivet delivery unit using the optical sensor of the sensor arrangement.

16. The method as claimed in claim 15 , wherein the control unit actuates a robot to pick up a rivet element on the basis of the position and/or alignment of the rivet elements.

17. The method as claimed in claim 9 , wherein the visual axis of the optical sensor directed to the rivet delivery unit and the visual axis of the optical sensor of the testing unit extend substantially perpendicularly to one another.
