Abstract

A container-processing machine includes a rotor with processing positions formed thereon, a transfer station, and a static lifting element used by all the processing positions. Each processing position has a processing head and a container carrier. The lifting element is a static lifting element that is used by all of the processing positions. When the processing position is at the transfer station, the lifting element causes relative motion between a container carrier and a processing head of the processing position. This causes the processing position to transition between receiving and discharge states.

First claim

Having described the invention, and a preferred embodiment thereof, what is claimed as new, and secured by letters patent is:

1. An apparatus for container processing, said apparatus comprising a container-processing machine that comprises a first transfer station and a rotor that is configured to be driven to rotate about a vertical machine axis thereof and that has processing stations formed thereon, wherein each of said processing stations comprises a processing head, a container carrier, a first static lifting element, and an associated drive for said first static lifting element, wherein said first static lifting element serves all of said processing stations, wherein said container-processing machine is specifically designed to carry out a method that comprises causing said rotor to bring a processing position to said first transfer station, and, using said first static lifting element, causing relative movement between a processing head and a container carrier of said processing station.

2. A method comprising operating a container-processing machine that comprises a first transfer station and a rotor that is configured to be driven to rotate about a vertical machine axis thereof and that has processing stations formed thereon, wherein each of said processing stations comprises a processing head, a container carrier, a first static lifting element, and an associated drive for said first static lifting element, wherein said first static lifting element serves all of said processing stations, wherein operating said container-processing machine comprises causing said rotor to bring a processing position to said first transfer station, and, using said first static lifting element, causing relative movement between a processing head and a container carrier of said processing station.

3. The method of claim 2 , wherein causing relative movement comprises, using said first static lifting element, lifting said container carrier into a raised state, and, while said container carrier is in said raised state, locking said container carrier in said raised state until said structure is to be lowered by said first static lifting element.

4. The method of claim 2 , further comprising driving said rotor in steps.

5. The method of claim 2 , further comprising causing a transport star to transfer containers that are to be processed to said container-processing positions and to remove processed containers from said container-processing positions.

6. The method of claim 2 , further comprising engaging said processing station with a coupling piece when said processing position moves to said first transfer station.

7. The method of claim 2 , further comprising, using said first static lifting element, providing a lifting service at both said first transfer station and at a second transfer station.

8. The method of claim 2 , further comprising causing said first static lifting element to provide lifting services at said first transfer station and causing a second static lifting element to provide lifting services at a second transfer station that is separated from said first transfer station by a first angular range, wherein said second transfer station is separated from said first transfer station by a second angular range that, when added to said first angular range, sums to three hundred and sixty degrees of arc, wherein said first and second angular ranges are of unequal extent, said first angular range being smaller than said second angular range, and establishing a drive connection between said first static lifting element and said container carrier only when said processing position is disposed within said first angular range.

9. The method of claim 2 , further comprising, using a coupling piece that forms an undercut, engaging said processing position when said processing position moves to said first transfer station.

10. The method of claim 2 , further comprising establishing a drive connection between said first static lifting element and said container carrier only when said processing position is disposed at said first transfer station.

11. The method of claim 2 , further comprising, using said container-treatment machine, sterilizing containers.

12. The method of claim 2 , wherein causing relative movement comprises, using said first static lifting element, lifting said processing head into a raised state, and, while said processing head is in said raised state, locking said processing head in said raised state until said processing head is to be lowered by said first static lifting element.

13. The method of claim 2 , further comprising driving said first static lifting element with an electric linear drive.

14. The apparatus of claim 2 , further comprising providing a coupling piece for engagement with said container carrier and, when said processing position moves to said first transfer station, causing said coupling piece couple said processing head and said first static lifting element to form a drive connection.

15. The method of claim 2 , further comprising providing said first static lifting element at said first transfer station.

16. The method of claim 2 , causing said first static lifting element to provide lifting services at said first transfer station, causing a second lifting element to provide lifting services at a second transfer station, and forming a drive connection between said processing head and said first static lifting element only when said processing position is disposed within a smaller of two angular ranges that separate said first and second transfer stations from each other and that, when combined, define a circle.

17. The method of claim 2 , further comprising using said container-treatment machine to fill containers using said container-treatment machine.

18. The method of claim 2 , further comprising driving said first static lifting element by causing movement of a pneumatic lifting cylinder.

19. The method of claim 2 , further comprising providing lifting service at said first transfer station using said first static lifting element and providing lifting service at a second transfer station using a second static lifting element.

20. The method of claim 2 , further comprising, using a coupling piece that forms an opening, engaging said processing position when said processing position moves to said first transfer station.

21. The apparatus of claim 2 , further comprising engaging said processing head with a coupling piece to create a drive connection between said first static lifting element and said processing head when said processing position moves to said first transfer station.

22. The method of claim 2 , further comprising providing, at most, one static lifting element for said container-processing machine.

23. The method of claim 2 , further comprising establishing a drive connection between said processing head and said first static lifting element only when said processing position is disposed at said first transfer station.
