Abstract

An apparatus for treating containers includes treatment positions arranged on a transport element with a rotor, a transport element, treatment blocks, and functional elements. The treatment positions are formed on the treatment blocks, with at least two per block. Each treatment position ha all functional elements required for treating a container. The functional elements can be for controlled relative movement between treatment blocks and containers, for control of controlled fluid paths for a fluid treatment medium, for monitoring the treatment process, a functional element for controlling the treatment process, or for actuating elements or drives. At least one common functional element needed for treatment of the containers is provided jointly for all treatment positions assigned to one treatment block.

Claims

1. An apparatus comprising a filling machine for filling containers with filling material, said filling machine comprising

a rotor and

treatment blocks provided on said rotor,

wherein each treatment block comprises

a liquid channel,

a liquid valve on said liquid channel,

a filling-material dispensing opening,

functional elements for controlling a container-treatment procedure, wherein said functional elements comprise at least one of:

a functional element for controlling actuation, a functional element for controlling relative movement between said treatment block and said containers, or a functional element for controlling fluid paths for a treatment medium,

treatment positions, each of which is configured to carry out said container-treatment procedure on one of said containers, said container being one that is arranged at said treatment position,

wherein all of said treatment positions share one of said functional elements, and

wherein each of said treatment positions further comprises a measuring system comprising a probe, said measuring system determining either depth or volume of filling material in a container,

said treatment block further comprising a pressure sensor for monitoring said container-treatment procedure.

2. The apparatus of claim 1, wherein all treatment positions of said treatment block and at least one of said functional elements form a common assembly that can be removed from said rotor as a unit and inserted into said rotor as a unit.

3. The apparatus of claim 1, wherein said functional element for controlling said relative movement comprises a container carrier and a lifting element that cooperates to control movement of containers relative to said treatment block and wherein said container carrier and said lifting element are controlled independently of container carriers and lifting elements for other treatment blocks.

4. The apparatus of claim 1, wherein said functional element for controlling said relative movement comprises a container carrier and a lifting element that cooperate to cause relative movement between said treatment block and said containers.

5. The apparatus of claim 1, wherein said treatment block further comprises a control valve, said control valve being arranged in a gas channel formed in said treatment block, said control valve being shared by all treatment positions of said treatment block.

6. The apparatus of claim 1, wherein said treatment block further comprises a control valve and a gas channel having said control valve arranged therein, said control valve being shared by all treatment positions of said treatment block.

7. The apparatus of claim 1, wherein said treatment block comprises liquid channels formed therein, gas channels formed therein, and control valves arranged in said gas channels, wherein said liquid channels, said gas channels, and said control valves are shared by all treatment positions in said treatment block.

8. The apparatus of claim 1, further comprising controlled gas-paths formed in said treatment block, wherein said controlled gas-paths are shared by all treatment positions of said treatment block.

9. The apparatus of claim 1, further comprising separate controlled gas-paths for each treatment position in said treatment block, wherein said controlled gas-paths are jointly controllable.

10. The apparatus of claim 1, wherein said measuring system comprises, at each treatment position, an axially-adjustable probe and a piston-cylinder arrangement, wherein said probe is configured to determine a fill depth of said filling material in a corresponding container, and wherein said piston-cylinder arrangement jointly adjusts heights for all probes of all treatment positions of said treatment block.

11. The apparatus of claim 1, further comprising centering bells that are movable synchronously with said rotor, wherein each centering bell corresponds to a treatment position, and wherein said centering bells are controllable independently of each other.

12. The apparatus of claim 1, wherein said measuring system comprises, at each treatment position, an axially-adjustable gas-return pipe and an electrical contact, wherein said gas-return pipe forms a gas-return channel, and wherein said electrical contact is arranged outside said gas-return channel and at a distance from an open lower end of said gas-return channel.

13. The apparatus of claim 1, wherein each treatment position comprises a centering bell for centering containers, wherein said centering bells can be raised and lowered individually along a direction parallel to a filling-element axis of filling elements in said treatment block.

14. The apparatus of claim 1, wherein each treatment position of said treatment block comprises a centering bell for centering a container at said treatment position, wherein said centering bell is movable along a filler-element axis, wherein said centering bells move jointly.

15. The apparatus of claim 1, wherein said pressure sensor is common to all treatment positions of a treatment block.

16. The apparatus of claim 1, wherein said treatment block comprises gas paths, pneumatically-actuated valves that control said gas paths, electrically-actuated pneumatic valves, and control lines that connect said pneumatically-actuated valves to said electrically-actuated valves.

17. The apparatus of claim 1, further comprising a common pneumatic valve, a control line, a first set of control valves assigned to a first treatment position of said treatment block, and a second set of control valves assigned to a second treatment position of said treatment block, wherein each control valve in said first set has a corresponding control valve in said second set, wherein each control valve in said first set and said corresponding control valve thereof in said second set are connected to said common pneumatic valve by said control line.

18. The apparatus of claim 1, wherein said functional element for controlling fluid paths for a treatment medium is configured to receive a sterilizing medium and wherein said functional element for controlling actuation, said functional element for controlling relative movement between said treatment block and said containers, and said functional element for controlling fluid paths for a treatment medium shared by all treatment positions of said treatment block.
