Abstract

A filling machine includes a multiple filling-element arranged for installation on a circulating rotor. The multiple-filling element includes individual filling-elements, each of which comprises a filling channel. Each filling channel has a dispensing opening, and an independently controllable liquid valve. The filling-element is formed for installation on an underside of a ring bowl provided on a rotor for holding liquid filling-charge. Other function elements are common to all the individual filling-elements. These function elements include controlled fluid paths.

Claims

1. An apparatus for filling containers with liquid filling-charge, said apparatus comprising a multiple filling-element, a circulating rotor, individual filling-elements, filling channels, filling-charge dispensing openings, independently controlled liquid valves, and a ring bowl, wherein said ring bowl forms an interior, wherein said ring bowl is provided at said rotor to provide said liquid filling-charge, wherein said multiple filling-element is arranged for installation on said circulating rotor, wherein said multiple filling-element comprises said individual filling-elements, wherein said multiple filling-element is formed for installation on an underside of said ring bowl, wherein each of said individual filling-elements comprises one of said filling channels, wherein each of said filling channels comprises one of said filling-charge dispensing openings, wherein each of said filling channels comprises one of said independently controllable liquid valves, wherein other function elements of said individual filling-elements are common to all individual filling-elements of said multiple filling-element, and wherein said other function elements are selected from the group consisting of controlled fluid paths, controlled liquid paths, gas paths, vapor paths, and control valves located on an element selected from the group consisting of liquid paths, gas paths, and vapor paths, said apparatus further comprising separate first and second paths, a control valve, and a structure selected from the group consisting of a common connection and a gas channel, wherein said paths are selected from the group consisting of gas paths and vapor paths, wherein said control valve has an open state and a closed state, wherein each of said individual filling-elements of said multiple filling-element comprises one of said paths, wherein, in said open state, said control valve connects said first and second paths with said structure, and wherein, in said closed state, said control valve separates said first and second paths from said structure and from each other.

2. The apparatus of claim 1, wherein said multiple filling-element comprises no more than two individual filling-elements.

3. The apparatus of claim 1, wherein said filling-charge dispensing openings, said liquid channels, and valve seats of one of said liquid valves and said function elements are provided in or at a filling-element underpart, and wherein said filling-element underpart is arranged for installation on said underside of said ring bowl.

4. The apparatus of claim 1, wherein said function elements are configured for arrangement in said interior, wherein said function elements are provided in each separately or independently for said individual filling-elements.

5. The apparatus of claim 1, wherein each of said individually controllable liquid valves comprises a valve body, a valve plunger, a valve seat, and an actuation device, wherein said valve body is provided at said valve plunger, wherein said valve body interacts with said valve seat, wherein said valve plunger extends at least part-way into said interior, wherein said valve plunger is connected to said actuation device, wherein said actuation device is provided on an upper side of said ring bowl outside said interior, and wherein said actuation device enables controlled opening and closing of said liquid valve.

6. The apparatus of claim 1, further comprising a gas channel, an additional valve, and a gas chamber, wherein said gas channel is open to said filling-charge dispensing opening, wherein said gas channel opens into said gas chamber via said additional valve, and wherein said gas chamber is formed in said interior.

7. The apparatus of claim 1, wherein said control valve comprises a first valve seat, a second valve seat, and a third valve seat, wherein said first valve seat is connected to said first path, wherein said second valve seat is connected to said second path, and wherein said third valve seat is connected to said structure.

8. The apparatus of claim 1, wherein each of said liquid valves comprises a valve seat, a valve plunger, and a valve body, wherein said valve body is provided at said valve plunger, wherein said valve body interacts with said valve seat, wherein said valve plunger is guided in or at an additional housing, wherein said housing is provided separately for each filling element at a filling-element underpart, wherein a side of said underpart projects above said housing, and wherein said side faces away from said filling-charge dispensing opening.

9. The apparatus of claim 8, further comprising a spring element, wherein said spring element is between said valve plunger and said additional housing, wherein said spring element pre-tensions said valve plunger and said valve body into one of a closed and open position of said liquid valve, and wherein said spring element is disposed in said interior.

10. The apparatus of claim 1, further comprising a filling machine having a vertical machine axis, wherein said circulating rotor is a rotor of said filling machine, wherein said circulating rotor rotates about said vertical machine axis, wherein said multiple filling-element is one of a plurality of identical multiple filling-elements disposed along a circumference of said rotor, each of which forms a filling point.

11. The apparatus of claim 10, wherein each of said filling points comprises a container-engagement structure and a lifting structure that corresponds to said container-engagement structure, wherein said container-engagement structure is selected from the group consisting of container carriers and centering elements, wherein said lifting structure is selected from the group consisting of a common lifting device and separate lifting devices, and wherein said container-engagement structure is movable along a filling-element axis by said lifting structure.

12. The apparatus of claim 10, wherein each of said individual filling-elements comprises a probe that is configured to extend into a container during filling thereof for controlling an amount of liquid filling-charge introduced into said container, wherein said probe comprises a gas tube that extends into a gas channel.

13. The apparatus of claim 10, and wherein parts of said multiple filling-elements are accommodated in said interior.

14. The apparatus of claim 13, wherein said parts are provided separately for said individual filling-elements.

15. The apparatus of claim 13, wherein said parts comprise function elements that are provided separately for said individual filling-elements.

16. The apparatus of claim 13, wherein each of said multiple filling-elements comprises an underpart, wherein each underpart comprises an independent housing for each individual filling-element of said multiple filling-element, wherein each individual filling-element extends into said interior, wherein further filling channels are formed in said individual filling-elements, wherein said further filling channels are connected to a filling channel in said filling-element underpart, and wherein said further filling channels are connected to said interior via openings.
