BACKGROUND
1. Technical Field
The present application relates to a beverage bottling plant for filling bottles with a liquid beverage material having a filling machine for filling bottles, cans and similar containers 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.
Filling valves of the prior art are equipped with gas cutoffs or gas locks. Filling valves with gas cutoffs are primarily used for the bottling of carbonated liquids that are introduced from a pressure vessel into a bottle that is connected with the filling mechanism. In the prior art, before the actual filling begins, the pressure between the bottle and the pressure vessel must be equalized so that the liquid can flow into the bottle as a result of hydrostatic pressure. During this process, the counter-pressure gas in the bottle is pushed back into the actual gas headspace of the filling bowl and is replaced by the liquid. For this purpose there is a return gas tube 11 which, with its bottom end surface, defines the boundary of the actual filling process, as soon as the liquid has reached said end surface.
Consequently, a further escape of the gas back into the pressure vessel is no longer possible. On such filling mechanisms there is a risk that the quantity of gas that is above the surface of the liquid will bubble up through the liquid duct, which is still open, and will thereby cause an after-running of the liquid that is above the valve seat. This situation can be effectively prevented by a gas cutoff that is located above the valve seat, for example.
On filling valves in which the filling level is determined essentially by a return gas tube 11, it is absolutely necessary to prevent the liquid flowing into the container from adhering to said return gas tube and to prevent it from flowing along said return gas tube 11 into the container to be filled. If the liquid should flow along the return gas tube 11 into the container, there is a risk that drops of liquid that adhere to the lower end of the return gas tube 11 can be carried along by the pre-pressurization gas that is flowing through the return gas 11 out of the container and accumulate inside the return gas tube 11, for example, as a result of which they can lead to a “sputtering” of the return gas tube 11 and ultimately to a disruption of the filling process.
To reliably prevent this situation, it has been known for some time that guide elements for the liquid, generally devices that are called screens or shields 16 can be located on the external contour of the return gas tube 11 that deflect the liquid far above the lower end of the return gas tube 11 and steer it toward the container wall. Because such return gas tubes 11 equipped with a screen 16 are expensive to manufacture, and as a rule must be changed depending on the model of bottle being used, many attempts have been made in the past to replace the screens 16 with other components. For example, in similar devices of the prior art, swirl inserts or torsion bodies have been located inside the liquid path which impart a rotational motion to the liquid, as a result of which the liquid flows into the container in contact with the inside wall of the container.
Because the use of gas cutoffs and swirl inserts or the use of gas cutoffs and return gas tubes with screens must be considered disadvantageous on account of the high costs of manufacturing, installation and maintenance, attempts have been made to combine gas cutoffs and swirl inserts.
For example, DE 41 40 524 C2 describes a thin, bell-shaped gas cutoff that can be manufactured in the form of a stamped sheet metal part, for example, in which the holes that run through said bell are oriented tangentially, so that a rotational motion is imposed on the liquid that flows through these openings.
The principal disadvantage of this device described in the prior art is that the material thickness of the bell is comparatively low. This low thickness is a disadvantage because the material thickness is equivalent to the length over which the liquid is guided, the purpose of which is to impose a rotational motion on the incoming liquid which has an essentially diffuse flow. The short length of the guidance therefore means that the new velocity vector, which comprises direction and velocity, can only be realized incompletely, especially since the liquid flows into the container only as a result of the hydrostatic pressure.
It is further disadvantageous that the bell shape of the gas cutoff requires a double deflection of the liquid, as a result of which the filling speed of the liquid is disadvantageously influenced. A gas cutoff of this type, on account of its large dimensions, also requires a great deal of space in the vertical direction, which is likewise disadvantageous for cost reasons and on account of the small amount of space available.
A comparable device was described in German Utility Model 78 11 788, in which the gas cutoff comprises an element that is in the shape of a truncated cone, the lower edge of which is formed by a comb-like structure. The slots in said comb-like structure are thereby realized so that they impart a centrifugal acceleration to the liquid as it flows into them.
Theoretically, the disadvantages cited above also apply to the device described by Utility Model 78 11 788. The manufacture of the comb-like structure described above is also very complex and expensive.
OBJECT OR OBJECTS
The object is to substantially eliminate or minimize the effects of the disadvantages described above. For this purpose the present application teaches a filling valve that is equipped with a gas cutoff with a swirling action, whereby the gas cutoff is realized essentially in the form of a flat element.
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”.

DESCRIPTION OF EMBODIMENT OR EMBODIMENTS
Developments, advantages and potential applications of the present application are described in greater detail below with reference to exemplary embodiments and the accompanying drawings. All the characteristics described and/or indicated in the illustrations, individually or in any arbitrary combination, are thereby the object of the present application, regardless of their placement in the claims or the cross-references among the claims. The text of the claims is also hereby incorporated by reference into this 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.
FIG. 1 shows a filling device of the prior art as discussed herein.
As shown in FIG. 2, the present application teaches that the gas cutoff with a swirl effect 13 can be realized in the form of a flat, plane element, as a result of which the multiple sharp deflection of the liquid required in the devices of the prior art is eliminated.
The gas cutoff 13 contains a plurality of passages 15, each of which represents a connection between the upper side and the underside of the gas cutoff 13.
In an additional advantageous realization, the present application teaches that in addition or also exclusively, there are recesses, e.g. fin-shaped recesses, which at least partly interrupt the radial outer contour/the peripheral surface of the gas cutoff 13.
Passages 15 and/or recesses and/or their side walls have an inclination with respect to the vertical, so that the liquid flowing through them takes on a velocity vector which contains, among other things, a velocity component in the peripheral direction with respect to the valve axis. As a result of this velocity component, a rotational movement of the liquid is realized, as a result of which the liquid, during its further travel, comes into contact first with the inside wall of the filler valve and, as it flows into the container 1, with its inner wall.
For the inclination of the passages 15 and/or recesses 15, the present application teaches that said inclination first runs in the peripheral direction. The present application also teaches that the inclination is realized as a function of the location where the filling machine is to be used, so that the effect of the Coriolis force that occurs during these flow processes is utilized and/or positively assisted.
On filling machines that are designed to be used in the earth's Northern Hemisphere, the inclination should be such that the liquid rotates in the clockwise direction, viewed in the direction of the flow. The opposite applies for filling machines that are designed to be used in the Southern Hemisphere.
The present application also teaches that the passages can also be inclined in the radial direction, so that the liquid is additionally guided toward the inside walls of the filling valve and container 1.
For the realization of the passages 15 and/or recesses, this embodiment teaches that said passages and/or recesses can be round, oval, square, rectangular, polygonal or elliptical, or realized in any other desired shape.
The present application also teaches that the profile of the passages 15 or of the recesses can be linear as well as non-linear, in other words the profile of the passages 15 can also be curved.
In an additional, altogether advantageous development of the present application, the parameters of the gas cutoff 13 such as, for example, its thickness, size of the passages 15 or recesses and their inclination can be customized to the specific characteristics of the liquid being bottled, such as its viscosity or surface tension, so that the characteristics of the gas cutoff 13 such as gas-tightness, swirling action and filling capacity can be optimally coordinated with one another. This system coordination is naturally also and in particular appropriate when a plurality of liquids are to be processed in alternation with a single filling machine.
As a result of the advantageous configuration of the installation space 14 for the gas cutoff 13, it is possible without problems or substantial effort to use gas cutoffs 13 of different thicknesses.
In an additional advantageous development of this invention, which is predominantly but not exclusively suitable for the bottling of beverages containing fruit pulp, for example, the present application teaches that the gas cutoff 13 can be realized with a funnel-shaped or cone-shaped upper side, analogous to one or more embodiments disclosed in an additional application by the same applicant, specifically U.S. application Ser. No. 11/0 82,236 filed Mar. 16, 2005, which application is incorporated by reference herein. As a result of this particularly shaped upper side, a self-cleaning action of the gas cutoff 13 is carried out during the bottling of beverages that contain fruit pulp.
The size, shape, angle, diametrical dimension, cross section, and contour of the passages 15 are configured to take into effect the Coriolis force for the latitude of the bottling plant location, the viscosity of the fluid being bottled, the amount and size of pulp in the fluid, and the temperature of the fluid being bottled. Further, the passages 15 are designed to minimize gas bubbling back up through the passages 15 upon a bottle being filled, to substantially prevent liquid beverage from coming into contact with the return gas tube in order to prevent drops of liquid from entering the return gas tube during the evacuation of gas from a bottle being filled, and to minimize filling time. Each element of the design of the passages 15 may be determined by experimentation with different types of fluids, such as fluids with different viscosities or varying amounts of pulp.
FIG. 3 shows a top view of one possible embodiment of the gas cutoff 13. According to this possible embodiment, the passages 15 comprise a circular open top end and a circular open bottom end, as well as a cylindrical inner wall portion through which a liquid beverage can flow. The open top end is offset from the open bottom end to permit the flow of liquid beverage in a circular or swirling motion in order to guide the liquid beverage toward the inside walls of the filling valve and container 1. In this embodiment, the passages 15 are disposed radially and concentrically about the gas cutoff 13. FIG. 3 shows two sets of passages for illustrative purposes, and it is to be understood that any number of additional passages could be included in different possible embodiments. In at least one embodiment, the passages as shown in FIG. 3 could continue about the entirety of the gas cutoff.
FIG. 4 shows a top view of another possible embodiment of the gas cutoff 13. In this possible embodiment, the passages 17 are offset diagonally such that they are pointed radially outward in order to further direct liquid beverage toward the inside walls of the filling valve and container 1. FIG. 4 shows two sets of passages for illustrative purposes, and it is to be understood that any number of additional passages could be included in different possible embodiments. In at least one embodiment, the passages as shown in FIG. 4 could continue about the entirety of the gas cutoff.
FIG. 5 shows a top view of another possible embodiment of the gas cutoff 13. In this possible embodiment, the outer and inner passages 19 are staggered with respect to one another about the gas cutoff 13, rather than being disposed radially, as shown in FIGS. 3 and 4. FIG. 5 shows two sets of passages for illustrative purposes, and it is to be understood that any number of additional passages could be included in different possible embodiments. In at least one embodiment, the passages as shown in FIG. 5 could continue about the entirety of the gas cutoff.
FIGS. 6 to 9 show top views of different embodiments of the gas cutoff 13, having different shaped passages. FIG. 6 shows ellipse-shaped passages 21. FIG. 7 shows hexagonally-shaped passages 23. Please note that any polygonal shape may be used for the passages, such as triangles, pentagons, heptagons, octagons, decagons, etc. FIG. 8 shows square-shaped passages 25. FIG. 9 shows rectangular passages 27. FIGS. 6 to 9 show two sets of passages for illustrative purposes, and it is to be understood that any number of additional passages could be included in different possible embodiments. In at least one embodiment, the passages as shown in FIGS. 6 to 9 could continue about the entirety of the gas cutoff.
FIG. 10 shows a top view of another possible embodiment of the gas cutoff 13. In this possible embodiment, the circular passages 29 are arranged linearly about the gas cutoff 13. The passages 29 run in a single file line on each side of the gas cutoff 13, such that they essentially form the shape of a square. FIG. 10 shows the passages 29 angled diagonally toward the inside walls of the filling valve and the container 1. However, the passages 29 may also be angled such that the open top end of each passage and the open bottom end of each passage lie on the same line.
FIG. 11 shows a side cross sectional view of one possible embodiment of the gas cutoff 13. In this possible embodiment, the passages 33 are angled toward the inside walls of the filling valve and the container 1. The inner walls of the passages through which liquid beverage flows during filling are straight and linear in this embodiment. FIG. 12 is similar to FIG. 11, but shows an embodiment where the passages 35 are curved.
FIG. 13 shows a side cross sectional view of another possible embodiment of the gas cutoff 13. In this possible embodiment, the passages 37 are conically shaped. In other words, the open top ends of the passages 37 have a wider diameter than the open bottom ends. Conversely, FIG. 14 shows another possible embodiment with conical passages 39, wherein the open top ends of the passages 39 have a smaller diameter than the open bottom ends.
FIG. 15 shows a side cross sectional view of another possible embodiment of the gas cutoff 13. In this possible embodiment, the inner walls of the passages 41 are substantially hourglass-shaped. In other words, the diameter of the open top ends and the open bottom ends of the passages 41 are substantially equal, but the inner walls of the passages have a substantially smaller diameter at the center of the passages than at the open top ends and bottom ends.
FIG. 16 shows a side cross sectional view of another possible embodiment of the gas cutoff. In this possible embodiment, the top of the gas cutoff 13 comprises a cone-shaped or funnel-shaped top portion 50. FIG. 17 shows a top view of another possible embodiment of the gas cutoff 13. In this possible embodiment, the gas cutoff 13 comprises fin-shaped recesses 60 which at least partly interrupt the radial outer contour or peripheral surface of the gas cutoff 13. FIG. 17 shows an embodiment with six recesses 60 for exemplary purposes, and embodiments with more or fewer recesses are within the scope of the present application. The additional embodiments of the gas cutoff disclosed herein could also be modified to include the recesses 60.
FIG. 18 shows a side cross sectional view of an example of a passage 15. The passage 15 can be disposed in the gas cutoff 13 at an angle, represented in FIG. 18 by angles A and B. The angle A is defined by a line L along the central axis of the passage and a radius of the gas cutoff 13, which angle A could be between 45° and 90°, including numbers in tenths of a percent, such as, for example, 45.1°, 45.2°, 45.3°, 45.4°, 45.5°, 45.6°, 45.7°, 45.8°, 45.9°, 50.0°, etc. The angle B is defined by the line L and a line perpendicular to a radius of the gas cutoff 13, which angle B could be between 0° and 60°, including numbers in tenths of a percent, such as, for example, 0.1°, 0.2°, 0.3°, 0.4°, 0.5°, 0.6°, 0.7°, 0.8°, 0.9°, 1.0°, etc. The angle of the passages 15 can be selected to cause the liquid beverage to flow out of the gas cutoff 13 in a circular or swirling motion in order to avoid liquid entering the gas return tube, to minimize filling time, and to minimize gas bubbling back up through the passages 15.
The present application relates to a filling valve for the bottling of liquids in bottles, cans and similar containers with a closable liquid duct and a gas cutoff associated with said liquid duct with a swirl effect, in which the gas cutoff is realized in the form of a flat, plane element.
