Handling module for handling motor vehicle wheels

1. A handling module for handling vehicle wheels in a system for the surface treatment thereof, the handling module comprising:

at least two gripping units each gripping unit comprising a carriage which is carried by a frame structure, each gripping unit being capable of gripping one single vehicle wheel, and whereof each gripping unit further comprises a plurality of contact pressure elements which are capable of being pressed against one or more counter-surfaces of an individual vehicle wheel,

and wherein a plurality of gripping units from the at least two gripping units each include a translational device by which the contact pressure elements are movable in relation to the frame structure and associated carriage by a motion component perpendicular to the frame structure to change the distance between the frame structure and the contact pressure element and between the carriage and the contact pressure element, wherein the motion component is also parallel to an axis of rotation of a gripped vehicle wheel,

wherein each single vehicle wheel gripped by the contact pressure elements of a gripping unit from the plurality of gripping units can be moved along the vehicle wheel's respective axis of rotation relative to the frame structure and the carriage by its respective contact pressure elements, independent of any movement or lack of movement by any other contact pressure elements or other vehicle wheels gripped by other contact pressure elements.

2. A handling module according to claim 1 , wherein contact pressure elements of a first gripping unit are movable independently of contact pressure elements of a second gripping unit.

3. A handling module according to claim 1 , wherein the gripping units are configured such that vehicle wheels gripped by the gripping units are aligned axially parallel to one another in relation to their axis of rotation.

4. A handling module according to claim 1 , wherein contact pressure elements of a gripping unit are each carried by a rod element and constructed as contact pressure plates which are capable of being pressed by means of an outer rim of the pressure plates against an outer face of a vehicle wheel.

5. A handling device according to claim 4 , wherein a gripping unit includes at least three rod elements having a contact pressure plate.

6. A handling device according to claim 1 , wherein at least one position of the contact pressure elements in relation to the frame structure is capable of being detected by at least one sensor device.

7. A handling device according to claim 6 , wherein the at least one sensor device is configured such that each position of the contact pressure elements is detectable.

8. A handling device according to claim 1 , wherein each single vehicle wheel is made of metal.

9. A handling device according to claim 1 , wherein each single vehicle wheel is engaged by its respective gripping unit by an outer rim of each of the plurality of contact pressure elements for the respective gripping unit.

10. A handling module for handling vehicle wheels in a system for the surface treatment thereof, the handling module comprising:

at least two gripping units each gripping unit comprising a plurality of carriages and a plurality of contact pressure elements, wherein each gripping unit is carried by a frame structure and is capable of gripping one single vehicle wheel with its plurality of contact pressure elements,

wherein each carriage carries a translational device, each translational device including a contact pressure element from the plurality of contact pressure elements, wherein each contact pressure element is movable by its translational device in relation to the frame structure and its associated carriage in a direction perpendicular to the frame structure independent of any contact pressure elements associated with any other gripping unit.

11. The handling module of claim 10 wherein each carriage is coupled to at least two rail arrangements, each carriage being movable laterally along the at least rail arrangements in a direction perpendicular to a direction of movement of the contact pressure elements.

12. The handling device according to claim 11 , wherein each carriage includes a motor, the motor facilitating lateral movement of the carriage along the at least two rail arrangements.

13. The handling device according to claim 12 , wherein each translation device includes a second motor, the second motor facilitating movement of the contact pressure element associated with the translation device and the carriage.

14. The handling module according to claim 10 , wherein each contact pressure element is carried by a rod element and constructed as contact pressure plates which are capable of being pressed by means of an outer rim of the pressure plates against an outer face of a vehicle wheel.

15. The handling device according to claim 14 , wherein a gripping unit includes at least three rod elements having a contact pressure plate.

16. The handling device according to claim 14 , wherein each single vehicle wheel is made of metal.

17. The handling device according to claim 14 , wherein each single vehicle wheel is engaged by its respective gripping unit by an outer rim of each of the plurality of contact pressure elements for the respective gripping unit.

18. The handling device according to claim 10 , wherein at least one position of the contact pressure elements in relation to the frame structure is capable of being detected by at least one sensor device.

19. The handling device according to claim 18 , wherein the at least one sensor device is configured such that each position of the contact pressure elements is detectable.
