Abstract

The disclosure relates to a stator module for a linear drive of a container-handling machine in the beverage processing industry, comprising a housing in which a core and at least one coil are arranged, wherein the stator module comprises a media supply for supplying a gas into the interior of the housing and the media supply is adapted to pressurize the interior of the housing, as well as a corresponding container-handling machine and a method of operating a container-handling machine.

First claim

What is claimed is:

1. A stator module for a linear drive of a container-handling machine, comprising:
a housing in which a core and at least one coil are arranged; and
a media supply for supplying a gas into an interior of the housing, wherein the media supply is designed to apply an overpressure to the interior of the housing to generate an overpressure in the interior of the housing, and wherein the stator module is adapted for use in a long-stator linear drive.

2. The stator module according to claim 1 , further comprising:
control electronics of the stator module at least partially arranged in the housing.

3. The stator module according to claim 2 , wherein the media supply is integrated as a hose in a control and power cable which comprises at least one line for the control electronics and at least one further line for a current supply of the at least one coil.

4. The stator module according to claim 1 , wherein the core comprises steel.

5. The stator module according to claim 1 , wherein the housing comprises a base body of a first material and an enclosure of a second material.

6. The stator module according to claim 5 , wherein the first material is aluminum or stainless steel and the second material is stainless steel.

7. The stator module according to claim 1 , wherein the media supply is designed as a separately guided hose.

8. The stator module according to claim 1 , wherein at least two coils are arranged in the housing.

9. A container-handling machine for handling containers, comprising:
a linear drive, wherein the linear drive comprises at least one stator module, the at least one stator module comprising:
a housing in which a core and at least one coil are arranged; and
a media supply for supplying a gas into an interior of the housing, wherein the media supply is designed to apply an overpressure to the interior of the housing to generate an overpressure in the interior of the housing, and wherein the stator module is adapted for use in a long-stator linear drive.

10. The container-handling machine according to claim 9 , wherein the linear drive comprises at least two stator modules and the media supply of each stator module of the at least two stator modules is connected to an additional media supply separately from the remaining stator modules of the at least two stator modules.

11. The container-handling machine according to claim 10 , wherein the at least one stator module further comprises control electronics at least partially arranged in the housing.

12. The stator module according to claim 11 , wherein the media supply is integrated as a hose in a control and power cable which comprises at least one line for the control electronics and at least one further line for a current supply of the at least one coil.

13. The container-handling machine according to claim 9 , wherein the linear drive comprises at least two stator modules each comprising a media supply, and wherein the media supplies of the at least two stator modules are arranged in series.

14. The container-handling machine according to claim 9 , wherein the container-handling machine is designed as a filler and the housing of the stator module consists of stainless steel.

15. The container-handling machine according to claim 9 , wherein the housing comprises a base body of a first material and an enclosure of a second material.

16. The container-handling machine according to claim 15 , wherein the first material is aluminum or stainless steel and the second material is stainless steel.

17. The container-handling machine according to claim 9 , wherein the media supply is designed as a separately guided hose.

18. The container-handling machine according to claim 9 , wherein the core comprises steel.

19. A method of operating a container-handling machine, comprising:
introducing a gas at an overpressure into an interior of a housing through a media supply to generate an overpressure in the interior of the housing, wherein the container-handling machine comprises a linear drive having a stator module, the stator module comprising the housing in which a core and at least one coil are disposed, the stator module further comprising the media supply, and wherein the stator module is formed for use in a long-stator linear drive.

20. The method according to claim 19 , wherein the gas is compressed air or an inert gas.
