These are at uniform angular and pitch intervals around the vertical axis MA machined at the same radial distance from this machine axis MA and provided at the same level, such that in the rotor rotational direction A to each treatment position 4a a treatment position 4b and each Treatment position 4b follow a treatment position 4a. The containers 2 to be filled are supplied to the filling positions 4a and 4b via a container inlet 1.1. The filled containers 2 are removed from the filling positions 4a and 4b at a container outlet 1.2.

On the circumference of the rotor 3 are distributed at equal angular and pitch intervals around the machine axis MA, provided in the same radial distance from this machine axis MA and at the same level Mehrfachfüllelemente 5, which are designed in the illustrated embodiment as a double or double filling. Each multiple filling element 5 functionally forms two individual filling elements 5.1 each for a treatment position 4a and a treatment position 4b. The Mehrfachfüllelemente 5 are each fully functional preassembled modules or assemblies that can be mounted in the manufacture of the filling machine 1 as such on the rotor 3 without much time and can be replaced in a possible defect or a change in the filling even without much time.

In detail, the Mehrfachfüllelemente 5 are mounted in the filling machine 1 respectively on the underside of a ring boiler 3.1, which is part of the rotor 3 and partially filled during the filling operation with the liquid medium this contents at all filling positions 4a and 4b.

Each filling position 4a and 4b has its own container carrier 6, on which the container in question 2 standing upright, that is arranged with its container axis coaxially or parallel or substantially coaxially or parallel to a vertical Füllelementachse FA and at least during filling in Seal is raised against the Mehrfachfüllelement 5. For the two container carrier 6, which are associated with the respective Mehrfachfüllelement 5, for example, separate lifting elements or a common lifting element are provided. Furthermore, each filling position 4a and 4b has its own centering tulip 7, which is provided in each case on a guide rod 8, is raised and lowered cam-mounted rotor 3 with this guide rod 8 and at least one ring seal for the sealing position of the raised container 2 on Mehrfachfüllelement 5 has ,

Each Mehrfachfüllelement 5 consists of a common for both Einzelfüllelemente 5.1 Füllelementunterteil 9, which in the illustrated embodiment, in terms of its outer shape flat or plate-shaped with a flat housing 9.1 and formed on the underside of the ring boiler 3.1 in a suitable manner, e.g. by screwing, and using at least one seal is fixed, in the region of two provided at the bottom or in the bottom of the ring vessel 3.1 openings 10. In Füllelementunterteil 9 Füllgut- or liquid channels 11 are formed whose center distance equal to the pitch of the treatment positions 4a and 4b, and which are respectively arranged congruently with an opening 10 on the upper side of the filling element lower part 9 resting against the underside of the annular bowl 3.1. The axis of each liquid channel 11 defines in the illustrated embodiment, parallel to the machine axis MA oriented Füllelementachse FA of the respective Einzelfüllelementes 5.1 or the respective filling position 4a or 4b.

At the bottom side facing away from the ring bowl 3.1, each liquid channel 11 forms an annular Füllgutabgabeöffnung 12, which is arranged in sealing position on Mehrfachfüllelement 5 container 2 with the container interior of this container 2 and via the flowing during filling the liquid product to the container interior.

The respective liquid channel 11 continues upward in another Füllgut- or liquid channel 13, which is formed in the interior of a tubular housing 14 which is arranged coaxially with the respective Füllelementachse FA, into the annular boiler interior 15 of the annular boiler 3.1 inside extends and ends at a distance from the top of the ring boiler 3.1. Each housing 14 is formed on its peripheral wall with a plurality of openings 14.1, for the passage of the liquid filling material from the ring bowl 3.1 or from the annular boiler interior 15 in the liquid channel 13 and via this in the liquid channel 11. At least during operation of the filling machine. 1 the annular boiler interior 15 is partially filled with the liquid contents, so that above the level of product in the ring bowl 3.1, a gas space 15.1, which is taken for example by a pressurized inert gas, such as CO2 gas, and a lower liquid space 15.2. The openings 14.1 are therefore in any case (also) in the region of the liquid space 15.2.

In each liquid channel 11, a liquid valve 16 is provided, which consists essentially of a formed on a valve stem 17 and cooperating with a valve seat in the liquid channel 11 valve body 18 by means of the valve stem 17 for the controlled opening and closing of the liquid valve 16 axially in the Füllelementachse FA is movable up and down. The valve stem 17 extends within the housing 14, is guided in or on this housing 14 and is preferably led out within the annular chamber interior 15 with an upper end of the upper side of the housing 14 sealed. This upper end of the valve stem 17 is connected via a quick or plug-in coupling with an actuating plunger 19. 1 of an actuating device 19, which is provided outside the annular boiler interior 15 at the top of the ring boiler 3.1. The actuating plunger 19.1 is sealed by using a bellows 20 through the top of the annular boiler 3.1. The actuating device 19 is, for example, a pneumatically actuated actuating device which is actuated via at least one electrically actuatable pneumatic valve for producing a controlled lifting movement of the valve tappet 17 in the filling element axis FA. With the actuators 19, the liquid valves 16 are each self-contained, i. independently controllable.

For the actuation of the valve stem 17 and thus also of the valve body 18 is within the annular vessel interior 15 and thereby preferably within the Gas space 15.1 a valve plunger 17 enclosing spring 21 is provided, which biases the valve body 18, for example, in its closed position.

In the illustrated embodiment, each valve stem 17 is formed with a coaxial with the Füllelementachse FA arranged gas channel 22 which continues below the valve body 18 down in a coaxial with the Füllelementachse FA arranged gas pipe 23, at the lower end of the gas channel 22 is open. The gas pipe 23, which is enclosed by the annular Füllgutabgabeöffnung 12 and extends into the filling of the respective container 2 in this through the container opening, serves as the filling height during filling determining probe. For this purpose, the upper end of the gas channel 22 opens into the gas space 15.1. Furthermore, in the illustrated embodiment in the gas channel 22 for opening and closing the gas channel 22, a valve 22.1 is provided, for example in the form of a check valve, which opens for flow in the direction from the lower end of the gas tube 23 into the gas space 15.1 for a flow in opposite Direction locks.

How the particular FIGS. 8 and 9 show in the Füllelementunterteil 9 or in the housing 9.1 more controlled steam and / or gas paths 24 are formed, which are provided for both Einzelfüllelemente 5.1 each Mehrfachfüllelementes 5 together and each lead through holes 24 in the liquid channels 11 of the two Einzelfüllelemente 5.1 and between the liquid valve 16 and the Füllgutabgabeöffnung 12. In the controlled steam and / or gas paths 14, two control valves 26 and 27 are provided, via which the steam and / or gas paths 24 can be controlled connected to a terminal 28, in turn is connected to a vacuum source or with a vacuum leading channel of the filling machine 1. The control valves 26 and 27 are pneumatically actuated control valves (pneumatic cylinder) of a control valve unit and are driven, for example, each by an electrically actuated pneumatic valve of a control block, not shown. In series with the control valve 26, a throttle 29 is provided with a reduced flow cross-section.

With the filling machine 1 or with the Mehrfachfüllelementen 5 different filling process for filling the container 2 are possible, including a pressure filling, and In this case, a biasing of the container 2 with the inert gas from the gas space 15.1 and then the actual filling of the container 2 by opening the respective liquid valve 16, and that is carried out at in sealing position on Mehrfachfüllelement 5 and 5.1 with closed control valves 26 and 27. The gas pipe 23 is sufficient when filling in the container 2 and serves as the filling level in the container 2 determining probe, ie after immersing the lower end of the gas pipe 23 in the rising in the container 2 Füllgutspiegel the further inflow of Filling finished automatically in the container. After the subsequent closing of both liquid valves 16 of the respective Mehrfachfüllelementes 5 takes place a simultaneous discharge of the two at the filling positions 4a and 4b of Mehrfachfüllelementes 5 arranged container 2 by opening only the control valve 26, so that relief takes place via the throttle 29 as a relief path gently and thereby a Foaming is avoided.

The biasing, for example, go an evacuation of the container 2 via the steam and / or gas paths 24 with open control valves 26 and 27 and / or rinsing the container 2 with the inert gas from the gas space 15.1 via the gas channel 22 and discharging the purge gas from the containers 2 via the steam and / or gas paths 24 with open control valves 26 and 27 ahead. Both the evacuation, as well as the rinsing carried out at the two filling positions 4a and 4b formed by the respective Mehrfachfüllelement 5 at the same time. In order to achieve the largest possible flow cross-section for this purpose, both the control valves 26 and 27 are preferably opened both during evacuation, as well as during rinsing.

It has been assumed above that the filling level is determined or controlled by the gas pipes 23. For this purpose, however, other functional elements may also be used, for example electrical probes, flow meters, etc., these functional elements in turn being provided independently for each filling station 4a and 4b.

The special feature of the filling machine according to the invention in general is that the filling positions 4a and 4b are each formed by multiple filling elements 5, that for each Mehrfachfüllelement 5, the functional elements for individual functions of the Einzelfüllelemente 5.1 are provided together, namely, for example, the control valves 26 and 27 or more control valves for the steam and / or gas paths 24 or other fluid paths, but that other functional elements for other functions, especially for those that are provided separately for each individual filling elements 5.1, such as the liquid valve 16 and the filling height and / or filling quantity determining elements.

Another special feature is that the Mehrfachfüllelemente 5 are fastened with their Füllelementunterteil 9 directly to the underside of the annular boiler 3.1, wherein in this Füllelementunterteil 9 then necessary for the common functions common functional elements are housed, and that the remaining functional elements of each Mehrfachfüllelementes 5, in particular, the functional elements necessary for the separate functions at least partially in the boiler interior 15 and ggs. on the upper side of the annular boiler 3.1 facing away from the filling element lower part 9, such as the housing 14, the valve tappet 17 of the liquid valve and the actuating elements 20.

The inventive design and in particular by the use of Mehrfachfüllelemente 5 results in significant advantages. Among other things a considerable cost saving by a reduced number of components, by reduction of the required material and the manufacturing costs. The common for the individual filling elements 5.1 fluid, steam or gas paths continues to result in a saving of control valves, a simplification of electrical control, a saving of electronic components, etc. In addition, the assembly time is reduced in the final assembly as integrated because of the inventive design Assembled modules and then completely or as fully functional units can be installed. Furthermore, a time-saving conversion of an existing filling machine 1 to other Mehrfachfüllelemente and / or other filling method is possible.

By arranging a part of the functional elements of the Mehrfachfüllelemente 5 within the annular boiler 3.1 further results in a space-saving compact design of the filling machine 1 overall.

The Figures 10 and 11 show a Füllelementunterteil 9a, which can find instead of the Füllelementunterteils 9 in the Mehrfachfüllelementen 5 of the filling machine 1 use. The Füllelementunterteil 9a in turn consists of a flat housing 9a.1, which is fixed in the installed state with its upper side 9a.1.1 using at least one seal, not shown, on the underside of the annular vessel 15, in such a way that in the housing 9a.1 provided and the respective liquid channel 11 forming openings 11.1 congruent with corresponding openings at the bottom of the annular vessel 15 are arranged.

In the housing 9a.1 three pneumatically actuated control valves 30 and 31 and gas channels forming gas channels are provided, namely a common for both Einzelfüllelemente 5.1 of Mehrfachfüllelementes 5 control valve 30 and one for each Einzelfüllelement 5.1 separately provided control valve 31. The control valves 31 are each a component of two controlled gas paths 24a, one of which is provided separately for each individual filling element 5.1 of a Mehrfachfüllelementes 5 and each connected to a for each gas path 24a independently provided valve seat 30.1 of the control valve 30. The control valve 30 connects in the open state, the terminal 28 via a formed in the housing 9 a.1 common gas channel 32 with the two gas paths 24 a. In the locked state, the control valve 30 not only blocks the connection between the port 28 and the gas paths 24a, but also separates the two gas paths 24a from each other.

The gas paths 24a and their branched gas channels 33 each open in the opening 11.1 and are for example individually controllably connected by the control valves 31 with another, eg a throttle also formed in the housing 9a.1 gas channel 34 of the respective gas path 24a.

The FIG. 12 shows another embodiment of the present invention. That in the FIG. 12 illustrated Füllventilunterteil 9a differs from the Füllventilunterteilen previously shown in particular by the fact that additional gas paths and throttles are provided.
By in the FIG. 12 illustrated embodiment, the problems are solved, which may arise when one of the bottles to be filled at a multiple filling during the treatment or even during the actual filling bursts.
For this purpose, it is provided that a throttle is arranged at least in one of the gas paths leading from an opening 11.1 to a control valve 30, 31. Furthermore, it is provided that the gas paths, which lead from different openings 11.1 to a common control valve 30, 31 are formed or connected to the common control valve 30, 31, that the gas paths only in a connection to each other, if the common control valve 30, 31 is open. If, however, the common control valve 30, 31 is closed, there is no connection between the respective gas paths, so that different pressure conditions can prevail in the respective openings 11.1. For example, in one opening 11.1 filling pressure prevail, while in another, the same control valve 30, 31 associated opening 11.1 ambient pressure prevails because the, the corresponding opening 11.1 associated bottle has burst.
If the control valve 30, 31 is now opened, the throttles arranged in the gas paths between the opening 11.1 and the control valve 30, 31 prevent pressure equalization between the openings 11.1. In particular, the throttles prevent too great a decrease in the pressure prevailing in the gas path or the opening 11.1, in which the container is intact and present, and thus there is the desired pressure provided for the respective method step.
Advantageously, the control valves 30, 31 connect the associated gas paths with at least one common channel or connection 28 provided for these gas paths, which can be provided, for example, for the application of negative pressure or else for rinsing or tempering.
