Abstract

A coupling is provided for the connecting of lines and includes a first coupling disc with first line connectors and a second coupling disc with second line connectors. Moreover, a first drive is provided in order to be able to move the two coupling discs axially with respect to each other. Moreover, a second drive is provided in order to be able to rotate the two coupling discs with respect to each other.

Claims

1. A coupling for the connecting of lines,

wherein a first coupling disc with first line convectors and a second coupling disc with second line connectors is provided,

wherein a first drive is provided in order to be able to move the two coupling discs axially with respect to each other,

wherein a second drive is provided in order to be able to rotate the two coupling discs with respect to each other.

2. The coupling according to claim 1

wherein the two coupling discs are arranged such as to be coaxial.

3. The coupling according to claim 1,

wherein the first coupling disc comprises first axial channels, which each are connected to one of the first line connectors each,

wherein the second coupling disc comprises second axial channels, which each are connected to one of the second line connectors each, and

wherein one seal each is arranged between the first channels and the second channels.

4. The coupling according to claim 3

wherein the seals are designed to be sleeve-shaped.

5. The coupling according to claim 1,

wherein an axle attached to the first coupling disc is provided and forms the rotary axis for the second coupling disc.

6. The coupling according to claim 5,

wherein an axle bearing is provided between the axle and the second coupling disc, and

wherein the axle bearing comprises an air purge system.

7. The coupling according to claim 1,

wherein at least a part of the first line connectors are arranged on a first pitch circle.

8. The coupling according to claim 7,

wherein a further part of the first line connectors are arranged on a second pitch circle.

9. The coupling according to claim 1,

wherein the first drive and/or the second drive comprises a pneumatic cylinder.

10. The coupling according to claim 1,

wherein the at least one part of the first and/or of the second line connectors is designed as hose nozzles.

11. The coupling according to claim 1,

wherein the one coupling disc comprises a positioning pin and the other coupling disc comprises sockets for accommodation of the positioning pin.

12. The coupling according to claim 1,

wherein at least one spacer is provided between the two coupling discs.

13. A powder coating facility comprising the coupling according to claim 1,

wherein a powder conveyor is provided that is connected to one of the first line connectors of the coupling by means of a powder line,

wherein a powder applicator is provided that is connected to one of the second line connectors of the coupling by means of a further powder line,

wherein a compressed air purging line that is connected to the coupling is provided.

14. The powder coating facility according to claim 13,

wherein the compressed air purging line is connected to one of the second line connectors of the coupling, and

wherein a further compressed air purging line that is connected to one of the first line connectors of the coupling is provided.

15. A method for cleaning of the powder coating facility according to claim 13,

wherein the coupling discs are arranged appropriately with respect to each other such that the compressed air purging line is connected to the powder line by means of the coupling,

wherein the powder line is purged in the direction of the powder conveyor by means of compressed air.

16. The method for cleaning of the powder coating facility according to claim 15,

wherein the coupling discs are arranged appropriately with respect to each other such that the further compressed air purging line is connected to the powder applicator by means of the coupling and the further powder line,

wherein the further powder line is purged in the direction of the powder applicator by means of compressed air.
