The filling machine having a gas tube being configured and disposed to permit evacuation of gas from a beverage bottle to a chamber of a return gas duct without the gas contacting liquid beverage material in a beverage storage reservoir to essentially prevent contamination of the liquid beverage material in said beverage storage reservoir by the gas being evacuated from the beverage bottle.

## Background
BACKGROUND
1. Technical Field
The present application relates to a beverage bottling plant for filling bottles with a liquid beverage having a filling machine as described herein below.
2. Background Information
A beverage bottling plant for filling bottles with a liquid beverage filling material can possibly comprise a beverage filling machine with a plurality of beverage filling positions, each beverage filling position having a beverage filling device for filling bottles with liquid beverage filling material. The filling devices may have an apparatus designed to introduce a predetermined volume of liquid beverage filling material into the interior of bottles to a substantially predetermined level of liquid beverage filling material. The apparatus designed to introduce a predetermined flow of liquid beverage filling material further comprises an apparatus that is designed to terminate the filling of the beverage bottles upon the liquid beverage filling material reaching the predetermined level in bottles. There may also be provided a conveyer arrangement that is designed to move bottles, for example, from an inspecting machine to the filling machine. Upon filling, a closing station closes the filled bottles. There may further be provided a conveyer arrangement configured to transfer filled bottles from the filling machine to the closing station. Bottles may be labeled in a labeling station, the labeling station having a conveyer arrangement to receive bottles and to output bottles. The closing station and the labeling station may be connected by a corresponding conveyer arrangement.
On filling machines for filling containers such as bottles, cans, canisters etc., it has been known for a long time that before the filling, the containers to be filled can first be treated with a vacuum and an inert gas such as CO2 or steam, for example. The purpose of this flushing is to reduce the germ content and oxygen content inside the containers.
For reasons of health and to increase shelf life, this process is customarily used in the bottling of liquids that are bacteriologically critical and/or oxygen-sensitive. The gases that must thereby be removed from the containers are generally removed via separate gas paths or ducts.
In addition to the use of separate gas paths or ducts, the prior art also describes configurations in which the gas is removed from the containers using what is termed a return gas pipe.
These return gas pipes, which in numerous configurations of filling machines are also used to exhaust the gas that escapes during the filling process from the containers being filled, generally empty into the storage reservoir for the goods being bottled, where they end above the fluid level in said storage reservoir.
In configurations of this type, in which ambient air, or at least the flushing gas that has been in contact with the container comes directly into contact with the liquid being bottled, there is necessarily an increased risk of contamination of the goods being bottled. This risk is particularly high if the return gas and the goods being bottled come into contact with each other over large areas.
DE 37 31 759 discloses the location on the peripheral surface of a ring bowl of a plurality of separate filling mechanisms that have a defined liquid volume to hold the liquid being bottled and a gas space that is located above the liquid being bottled. In this apparatus of the prior art, the respective return gas tube ends inside this separate filling mechanism. In this configuration, of course, the return gas initially comes into contact only with the volume of liquid being bottled that is located in the filling mechanism itself, as a result of which the risk of contamination is reduced, although it is impossible to fully rule out a more serious contamination of the liquid being bottled, because the return gas from any filling mechanism can travel through a large-diameter passage opening into the ring bowl.
DE 39 28 009 describes a filling machine with a separate return gas duct that is located above the storage reservoir. In this device, the return gas is transported via an additional shuttle valve either into the storage reservoir for the liquid being bottled and/or into the return gas duct. DE 39 28 009 also teaches that the pressure in the return gas duct is set lower than the pressure in the storage reservoir. Because of the shuttle valve that is provided and the different pressure settings, however, such a device is mechanically complex and expensive to manufacture.
OBJECT OR OBJECTS
The object of this invention is to substantially reduce or essentially eliminate the disadvantages described above. For this purpose the invention teaches a filling machine in which a return gas tube ends directly in a separate return gas duct, whereby said return gas duct is connected with the storage reservoir through an opening that has a small cross section area, and the return gas duct and storage reservoir are connected with a common source of negative pressure or vacuum and are at essentially the same pressure.
The above-discussed embodiments of the present invention will be described further hereinbelow. When the word “invention” or “embodiment of the invention” is used in this specification, the word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”. By stating “invention” or “embodiment of the invention”, the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.

DESCRIPTION OF EMBODIMENT OR EMBODIMENTS
Developments, advantages and potential applications of the invention are described below with reference to exemplary embodiments and to the accompanying drawings. All the features described and/or illustrated, individually or in any desired combination, are the object of the invention regardless of their combination or placement in the claims or the references to other claims. The text of the claims is also integrated by reference into the description.
FIG. 1A shows schematically the main components of one possible embodiment example of a system for filling containers, specifically, a beverage bottling plant for filling bottles B with at least one liquid beverage, in accordance with at least one possible embodiment, in which system or plant could possibly be utilized at least one aspect, or several aspects, of the embodiments disclosed herein.
FIG. 1A shows a rinsing arrangement or rinsing station 101, to which the containers, namely bottles B, are fed in the direction of travel as indicated by the arrow A1, by a first conveyer arrangement 103, which can be a linear conveyor or a combination of a linear conveyor and a starwheel. Downstream of the rinsing arrangement or rinsing station 101, in the direction of travel as indicated by the arrow A1, the rinsed bottles B are transported to a beverage filling machine 105 by a second conveyer arrangement 104 that is formed, for example, by one or more starwheels that introduce bottles B into the beverage filling machine 105.
The beverage filling machine 105 shown is of a revolving or rotary design, with a rotor 105′, which revolves around a central, vertical machine axis. The rotor 105′ is designed to receive and hold the bottles B for filling at a plurality of filling positions 113 located about the periphery of the rotor 105′. At each of the filling positions 103 is located a filling arrangement 114 having at least one filling device, element, apparatus, or valve. The filling arrangements 114 are designed to introduce a predetermined volume or amount of liquid beverage into the interior of the bottles B to a predetermined or desired level.
The filling arrangements 114 receive the liquid beverage material from a toroidal or annular vessel 117, in which a supply of liquid beverage material is stored under pressure by a gas. The toroidal vessel 117 is a component, for example, of the revolving rotor 105′. The toroidal vessel 117 can be connected by means of a rotary coupling or a coupling that permits rotation. The toroidal vessel 117 is also connected to at least one external reservoir or supply of liquid beverage material by a conduit or supply line. In the embodiment shown in FIG. 1A, there are two external supply reservoirs 123 and 124, each of which is configured to store either the same liquid beverage product or different products. These reservoirs 123, 124 are connected to the toroidal or annular vessel 117 by corresponding supply lines, conduits, or arrangements 121 and 122. The external supply reservoirs 123, 124 could be in the form of simple storage tanks, or in the form of liquid beverage product mixers, in at least one possible embodiment.
As well as the more typical filling machines having one toroidal vessel, it is possible that in at least one possible embodiment there could be a second toroidal or annular vessel which contains a second product. In this case, each filling arrangement 114 could be connected by separate connections to each of the two toroidal vessels and have two individually-controllable fluid or control valves, so that in each bottle B, the first product or the second product can be filled by means of an appropriate control of the filling product or fluid valves.
Downstream of the beverage filling, machine 105, in the direction of travel of the bottles B, there can be a beverage bottle closing arrangement or closing station 106 which closes or caps the bottles B. The beverage bottle closing arrangement or closing station 106 can be connected by a third conveyer arrangement 107 to a beverage bottle labeling arrangement or labeling station 108. The third conveyor arrangement may be formed, for example, by a plurality of starwheels, or may also include a linear conveyor device.
In the illustrated embodiment, the beverage bottle labeling arrangement or labeling station 108 has at least one labeling unit, device, or module, for applying labels to bottles B. In the embodiment shown, the labeling arrangement 108 has three output conveyer arrangement: a first output conveyer arrangement 109, a second output conveyer arrangement 110, and a third output conveyer arrangement 111, all of which convey filled, closed, and labeled bottles B to different locations.
The first output conveyer arrangement 109, in the embodiment shown, is designed to convey bottles B that are filled with a first type of liquid beverage supplied by, for example, the supply reservoir 123. The second output conveyer arrangement 110, in the embodiment shown, is designed to convey bottles B that are filled with a second type of liquid beverage supplied by, for example, the supply reservoir 124. The third output conveyer arrangement 111, in the embodiment shown, is designed to convey incorrectly labeled bottles B. To further explain, the labeling arrangement 108 can comprise at least one beverage bottle inspection or monitoring device that inspects or monitors the location of labels on the bottles B to determine if the labels have been correctly placed or aligned on the bottles B. The third output conveyer arrangement 111 removes any bottles B which have been incorrectly labeled as determined by the inspecting device.
The beverage bottling plant can be controlled by a central control arrangement 112, which could be, for example, computerized control system that monitors and controls the operation of the various stations and mechanisms of the beverage bottling plant.
The exemplary embodiment illustrated in FIG. 1 is a filling machine with a rotary-type construction, with a plurality of filling stations arranged on its periphery. Associated with each of these filling stations are, among other things, a centering element, a liquid valve and a return gas pipe 11. This return gas pipe 11 is located in the center of the liquid valve, and extends from the interior of the reservoir mouth to inside the return gas duct 13, whereby it runs all the way through the storage reservoir 12 that holds the liquid 20 being bottled.
The return gas duct 13 is located above the storage reservoir 12 and is advantageously realized in the form of an encircling, fully closed annular duct. However, it is possible that other duct shapes and/or locations may also be useful.
The return gas duct 13 and the storage reservoir 12 are connected to a joint source 15 of negative pressure or vacuum, whereby the connection to the storage reservoir 12 is accomplished using a controllable or adjustable gas flow valve 16.
In an additional advantageous realization of the invention, the return gas duct 13 and the storage reservoir 12 are each equipped with their own vacuum or negative pressure source 15.
There is a boring 17 for each return gas pipe 11, which boring 17 is coordinated with the diameter of the return gas pipe 11, in the cover of the storage reservoir 12 and which makes it possible to run the return gas pipe 11 through the cover of the storage reservoir 12. The diameters of the return gas tube 11 and the boring 17 are preferably coordinated so that the connection between the return gas duct 13 and the storage reservoir 12 is realized in the form of a circular ring-shaped surface that has only a small surface area, as a result of which the potential for contact between the return gas and the liquid being bottled, and therefore the risk of contamination, can be significantly reduced.
In one possible embodiment, the boring 17 may be hermetically sealed around the return gas pipe 11 to prevent any contact between the return gas and the liquid being bottled, and therefore to prevent the risk of contamination, such as for the bottling of sensitive liquids like wine. In another possible embodiment, there may be no seal around the boring 17 and the return gas pipe 11.
Configurations in which the area of the circular ring-shaped surface is less than 100 mm2 have been found to be particularly advantageous. It should be understood that the advantageous configuration of the circular ring-shaped surface of 100 mm2 is particular to the experiments made with available machines, and therefore it is possible and within the scope of the application that, for other machines, other configurations or cross sections may possibly be found to be practical, optimal, or advantageous.
To prevent the unnecessary introduction of gas not required by the filling process into the storage reservoir 12 and/or the return gas duct 13, the invention teaches the use of means that make it possible to securely close the upper end of the return gas pipe 11. These means—as illustrated by way of example in the accompanying drawings—can be a membrane closure 18 actuated by a pneumatic cylinder 19, and/or tappets, pistons or other suitable sealing elements. With regard to the actuation of these means, e.g. pneumatically actuated means, the invention teaches that they can be actuated electronically, for example, by at least one computer or control computer. The control computer that is already present on the filling machine can be used for this purpose, too, for example.
During the flushing or filling, gas or return gas is removed from the reservoir, and when the membrane closure 18 is opened, said gas or return gas travels through the return gas tube 11 into the return gas duct 13. As a result of the advantageous configuration of the boring 17, the operation of the vacuum source 15 and the appropriate setting of the gas flow valve 16, it is possible to regulate the gas flow between the components, i.e. the return gas pipe 11, return gas duct 13 and the storage reservoir 12, and to define its direction so that the gases exiting the return gas tube 11 go directly to the vacuum source 15 and do not penetrate into the storage reservoir 12, as a result of which contact between the liquid being bottled and the return gas can be securely prevented or at least minimized.
The safety of the bottling process can be further increased by a low but continuous gas flow out of the storage reservoir 12 into the return gas duct 13, because this gas flow that passes the boring 17 blocks the path through the hold formed by 17 for the return gas.
This invention also makes it possible to almost completely prevent gas movements inside the storage reservoir 12, as a result of which, in particular with sensitive liquids being bottled such as wine or certain fruit juices for example, undesirable losses of alcohol and/or highly volatile flavoring agents can be significantly reduced or even prevented altogether.
FIG. 1B is similar to FIG. 1, and shows a control device or computer 22 for actuating and controlling the means to securely close the upper end of the return gas pipe 11, examples of which means are described herein.
FIG. 1C is similar to FIG. 1, and shows an embodiment where the boring 17 is hermetically sealed around the return gas pipe 11 to essentially prevent any contact between the return gas and the liquid being bottled, and therefore to essentially prevent the risk of contamination, such as for the bottling of sensitive liquids like wine. The hermetic seal is represented by a box 30 in FIG. 1C.
With reference to FIG. 1D, with an increased demand for higher quality and stability of durability of beverages in containers, there is at hand a type of arrangement in which the handling positions are disposed in a closed space that is supplied with a special atmosphere. Such a space can be supplied with an inert atmosphere such as carbon dioxide, with a sterilizing atmosphere, or with hydrogen peroxide, and thus can ensure a treatment of the beverage that is low in oxygen and low in germs, this being of paramount importance for the quality of the beverage supply that is to be filled into the containers. Such handling machines are known in many varieties in the beverage industry. FIG. 1D is similar to FIG. 1, and shows an embodiment where the filling machine is enclosed in a clean room for aseptic bottling, which clean room is represented by a box 24 around the filling machine.
