Abstract

A filler element includes a valve arrangement that switches it between filling mode and CIP mode by controlling a connection between a chamber formed in a housing and a CIP channel formed from a valve body provided at a filling-height-controlling element. Axial movement of a filling-height-controlling element through an extension connected to the chamber controls mode-switching. In both modes, a continuous fluid connection exists between the extension's CIP connection and the CIP channel. Axial movement of the filling-height-controlling element also controls filling height in the container. In CIP mode, a CIP flow formed in the housing conducts liquid CIP medium out of the boiler, through the filling element, and out into a CIP channel.

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 filling a container with liquid filling contents, said apparatus comprising a filler element that switches between a filling mode and a CIP mode, wherein said filler element comprises
a filler element housing,
a liquid channel,
a dispensing opening,
a liquid valve,
a chamber,
an extension,
a filling-height-controlling element,
a valve body,
a first ring channel,
a connecting channel,
a seal, and
a flush closure element,
wherein said liquid channel is formed in said filler element housing,
wherein said liquid channel is configured to be connectable to a filling-contents boiler,
wherein said liquid valve is disposed in said liquid channel,
wherein said liquid channel forms said dispensing opening,
wherein said filling-height-controlling element controls filling height in said container,
wherein, during filling of a container, a first end of said filling-height-controlling element projects beyond said dispensing opening and extends into said container,
wherein axial movement of said filling-height-controlling element within an adjustable range adjusts said filling height,
wherein, in CIP mode, liquid CIP medium is conducted out of said boiler, flows through said filler element, and out of said filler element into said first ring channel,
wherein, in CIP mode, said flush closure element closes said filler element at said dispensing opening,
wherein said chamber is formed in said filler element housing,
wherein said extension connects to said chamber on an upper side of said filler element housing facing away from said dispensing opening,
wherein said filling-height-controlling element is guided through said extension,
wherein said connecting channel connects said extension to said first ring channel,
wherein, in CIP mode, said liquid CIP medium flows through said liquid channel, said chamber, and said extension,
wherein said seal blocks a fluid connection between said chamber and said first ring channel when said filling element is in filling mode,
wherein said seal clears said fluid connection between said first ring channel and said chamber when said filling element is in CIP mode,
wherein said seal is provided on said filling-height-controlling element and moves with said filling-height-controlling element,
wherein, during said filling mode, said seal blocks said fluid connection between said chamber and said connecting channel of said extension,
wherein, during CIP mode, said seal opens said fluid connection between said chamber and said connecting channel of said extension,
wherein opening and closing of said seal is controlled by axial movement of said filling-height-controlling element, and
wherein, in said filling mode and in said CIP mode, a continuous fluid connection exists through said connecting channel between said extension and said first ring channel.

2. The apparatus of claim 1 , wherein said seal blocks the entirety of said fluid connection.

3. The apparatus of claim 1 , wherein said extension comprises a cylinder, wherein said seal defines a piston that moves within said cylinder in response to axial movement of said filling-height-controlling element, and wherein said piston selectively blocks said fluid connection between said chamber and said connecting channel.

4. The apparatus of claim 3 , wherein said seal is configured to open said fluid connection between said chamber and said connecting channel by moving out of said extension and into a volume that has a cross-section that is larger than said seal.

5. The apparatus of claim 3 , wherein said chamber has a cross-section that is larger than said seal, and wherein said seal is configured to open said fluid connection between said chamber and said connecting channel by moving out of said extension and into said chamber.

6. The apparatus of claim 1 , further comprising a valve tappet for said liquid valve and a second ring channel, said second ring channel being disposed between said valve tappet and said filling-level controlling element, wherein said valve tappet comprises a pipe that is coaxial with a filler element axis, wherein said filling-height-controlling element is guided through said pipe, wherein said second ring channel is open on an underside of said filler element, and wherein said second ring channel opens into said chamber.

7. The apparatus of claim 6 , wherein said flush closure is configured to selectively direct said liquid CIP medium to run out of said filling-contents boiler, via said liquid channel, via said opened liquid valve, via an interior of said flush closure element, via said second ring channel, via said chamber, through an opening formed from said chamber into said extension as a result of movement of said seal into said chamber, and via said extension, which is connected to the said first ring channel.

8. The apparatus of claim 1 , wherein said connecting channel of said extension is formed from a connecting channel in said filler element housing, and wherein said connecting channel is connected to said ring channel.

9. The apparatus of claim 1 , wherein said filling-height-controlling element comprises a return gas tube.

10. The apparatus of claim 1 , wherein said filling-height-controlling element comprises a Trinox tube.

11. The apparatus of claim 1 , wherein said filler element is configured for filling said container at under-pressure.

12. The apparatus of claim 1 , wherein said filler element is configured for filling said container at ambient pressure.

13. The apparatus of claim 1 , wherein said filler element is a multiple-filler element comprising a plurality of individual filler elements.

14. The apparatus of claim 13 , wherein said filling-height-controlling element comprises a plurality of return gas tubes, and wherein said apparatus further comprises a common adjustment device for adjusting filling heights of said individual filler elements of said multiple filler element.

15. The apparatus of claim 1 , wherein said filling-height-controlling element comprises a plurality of return gas tubes, said apparatus further comprising a common control valve to connect said return gas tubes to a filling-contents boiler.

16. The apparatus of claim 1 , wherein said filling-height-controlling element comprises a plurality of return gas tubes, and wherein said apparatus further comprises a non-return valve arrangement to connect said return gas tubes to a filling-contents boiler.

17. The apparatus of claim 16 , wherein said non-return valve arrangement comprises at least one non-return valve for each return gas tube.

18. The apparatus of claim 16 , wherein said non-return valve arrangement opens into the said chamber, wherein said non-return valve arrangement at least one of blocks or constricts a flow in and out of said chamber.

19. The apparatus of claim 16 , wherein at least one non-return valve of said non-return valve arrangement first opens at a pressure that exceeds a filling pressure.

20. The apparatus of claim 1 , further comprising a rotor, wherein said filler element is one of a plurality of identical filler elements disposed on a periphery of said rotor.
