Description

BACKGROUND

1. Technical Field

This application relates to a beverage filling machine for filling cans with a liquid beverage. This application further relates to a filling element with a rinsing cap which can be moved between a radially inner, non-engaged position and a radially outer, engaged position, whereby the rinsing cap is held and guided by radially inward guides, wherein the rinsing cap is additionally received and/or held in its engaged position by at least one receptacle. Advantageous developments of at least one possible embodiment are described herein below.

2. Background Information

Filling elements, in particular those for use on rotary-type filling machines, are known in an extremely wide variety of models. It is also known that these filling elements as well as the surfaces of the filling elements that come into contact with critical areas of the containers during the filling process can be cleaned and/or rinsed in a cleaning or rinsing phase with a liquid and/or vapor medium, for example. Critical areas of the container are, among others, the interior surfaces of the container and the surface areas in the vicinity of the mouth of the container.

For the cleaning and/or rinsing of the filling elements, the conventional practice is to apply cap-like closing elements to the filling elements in the vicinity of the dispensing openings, by means of which, during the filling process, the liquid being bottled is introduced into the containers, and specifically to form closed rinsing spaces. These cap-like closing elements are called “rinsing caps” below.

The cleaning and/or rinsing of the filling elements, in particular of their ducts and their surface areas that come in contact with critical areas of the containers during the filling process, whereby the surfaces in question can also be sealing surfaces, can then be performed by, among other things, the rinsing and/or cleaning medium that is made to flow through the individual closed rinsing space, and which flows into the rinsing space, for example, via the respective dispensing opening of the liquid channel, and is removed via at least one additional duct that emerges in the rinsing space, for example via the back-gas duct.

The placement and fixing in position of the rinsing caps in preparation for the rinsing or cleaning phase as well as the removal of these rinsing caps after the rinsing and cleaning phase is a complex, expensive and time-consuming process.

Because the handling of the rinsing caps is particularly time-consuming and expensive when the related activities must be performed manually, numerous suggestions have been made in the past to automate these activities.

In this context, it is worth nothing that bottles that are made of glass can be manufactured in almost any desired diameter ratios between the largest diameter of the bottle and the diameter of the mouth of the bottle. On the other hand, in the manufacture of cans, which are generally made of sheet metal, there are only small ratios between the largest and the smallest diameter of the can.

Consequently, the filling positions of can-filling machines can be at a smaller distance from one another than the filling positions of bottle-filling machines, because bottle-filling machines must also be capable of filling molded bottles that are not cylindrical but can have a bulge, for example.

For cost-reduction reasons, the filling positions of can filling machines are therefore located very close together, which causes problems in the arrangement of automatically movable rinsing caps.

A device for the automatic movement of rinsing caps is described in Japanese Patent No. 9-309593 A, for example. On this device, two rinsing caps each are held on a carrier element, whereby the carrier element is held on a sled that is oriented radially in relation to the rotating carousel of the filling machine. This sled can in turn be displaced radially from a first, inner position into a second, outer position, as a result of which the rinsing caps are brought into a functional connection with the associated filling valves. The guides and thus also the points of the application of force on the sled are located between the associated filling valves on a radially inner position.

This geometric configuration of two rinsing caps on a carrier element results in a significant disadvantage of the device described in Japanese Patent No. 9-309593A, but also in all additional corresponding devices in which the rinsing caps are moved from a radially inner position into a radially outer position.

The cans to be filled by can-filling machines have diameters between 53 and 82 mm, for example. The filling valves and thus also the associated rinsing caps have corresponding diameters. The cleaning or rinsing of the filling valves takes place at pressures of up to 3×10⁵ Pa.

On the basis of these parameters, there is a force of up to 1500 N per rinsing cap, which in connection with the disadvantageous location of the points of the application of force can result in an elastic deformation of the rinsing cap fastening.

In practice, it is frequently observed that the seals of the rinsing caps sometimes lose some or all of their sealing function as a result of these plastic deformations, as a result of which the rinsing or cleaning fluid, which is under high pressure, escapes and contaminates the filling valve and/or the filling machine.

This escape of rinsing or cleaning fluid is generally considered a disadvantage.

The prior art also describes a device as claimed in German Patent No. 940 38 32. In this device, the vertically movable bell that creates the actual sealed connection between the can and the filling valve is located inside a surrounding tube. Attached to this tube which surrounds the sealing bell are elements that hold the rinsing cap, whereby these receptacle elements are located on the circular arc of the filling valves.

Of course, this device overcomes the disadvantage of the unfavorable location of the points of the application of force, although the location of the receptacle elements on the circular arc of the midpoints of the filling valves is particularly disadvantageous, because the individual filling elements must, under some conditions, be located at an increased distance from one another. A device of this type is also mechanically complex and expensive.

OBJECT

An object of at least one possible embodiment is therefore to indicate a filling element equipped with a rinsing cap that essentially eliminates or minimizes the above disadvantages and is held in the sealed position so that leaks can be reliably prevented.

SUMMARY

To accomplish this object, at least one possible embodiment teaches a filling element for use on rotary-type filling machines for filling cans or similar containers, with a rinsing cap which can be moved between a radially inner, non-engaged position and a radially outer, engaged position, whereby the rinsing cap is held and guided by radially inward guides, wherein the rinsing cap is additionally received and/or held in its engaged position by at least one receptacle. On the filling element according to at least one possible embodiment, the rinsing cap, which is located or held in a receptacle, for the formation of the individual closed rinsing space is moved from a first, radially inner non-engaged position into a second, radially outer engaged position, whereby the rinsing cap is fixed in position by an additional holding element to maintain the seal seat.

DESCRIPTION OF EMBODIMENT OR EMBODIMENTS

Developments, advantages and potential applications of the invention will become apparent on the basis of the following description of the exemplary embodiments and of the accompanying drawing. All the characteristics described and/or illustrated are the object of the invention, individually or in any possible combination, regardless of their placement in the claims or the references between claims. The text of the claims is simultaneously incorporated 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 can filling plant for filling cans C 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 cans C, 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 cans C 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 cans C 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 cans C 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 cans C 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 cans C, 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 cans C, there can be a beverage can closing arrangement or closing station 106 which closes the cans C. The beverage can closing arrangement or closing station 106 can be connected by a third conveyer arrangement 107 to a beverage can 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 can labeling arrangement or labeling station 108 has at least one labeling unit, device, or module, for applying labels to cans C. 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 cans to different locations.

The first output conveyer arrangement 109, in the embodiment shown, is designed to convey cans C 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 cans C 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 cans C. To further explain, the labeling arrangement 108 can comprise at least one beverage can inspection or monitoring device that inspects or monitors the location of labels on the cans C to determine if the labels have been correctly placed or aligned on the cans C. The third output conveyer arrangement 111 removes any cans C which have been incorrectly labeled as determined by the inspecting device. In other possible embodiments, cans may not require the addition of any information or cans may not require labeling, or cans may have the required information added or may be labeled prior to entering the rinsing arrangement or rinsing station 101, and therefore the labeling station 108 and the third output conveyer arrangement 111 may possibly be omitted.

The beverage can filling 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 can filling plant.

As illustrated in FIG. 1, the rinsing cap 13 can be moved from a first, radially inner, non-engaged position A into a second, radially outer, engaged position B. The movement from one position to the other can be controlled in a known manner by means of a curved track control system 14, for example.

On account of the very close-together arrangement of the filling elements on can-filling machines, only a few millimeters of space remain between the individual bells 16 that create the sealed connection with the cans 15.

Accordingly, in a manner that is in itself known, the invention provides guides 17 for the rinsing caps 13 not on the circular arc of the midpoints of the filling valves and thus between the individual bells 16, but in a radially inner position.

According to at least one possible embodiment, to retain the sealed position during the rinsing process, the rinsing cap 13 in its radially outer, engaged position B is held in at least one additional element, for example a receptacle 18.

For this purpose, the rinsing cap 13 is preferably held with its forward end in the at least one receptacle 18, whereby it is particularly advantageous if the at least one receptacle 18 is located radially outside the circular arc of the filling valves with reference to the axis of rotation of the can-filling machine.

The forward end of the rinsing cap 13, as can be seen in FIG. 2, is positioned further away in a radial direction from the center of the rotor than all other portions of the rinsing cap 13 The receptacle 18 serves as an end support structure which supports the forward end of the rinsing cap 13 when the rinsing cap 13 is extended radially, such as shown in FIG. 1D. The end support structure 18 is positioned a distance from the radial guide structure 17, which distance, as can be seen in FIGS. 1 through 1D, may be greater than or equal to the diameter of the dispensing opening. The end support structure 18 has a slot therein for receiving solely the forward end of the rinsing cap 13, which is shown in FIGS. 1 through 1D. The slot is elongated so as to receive and support the forward end of the rinsing cap 13 across the width of the rinsing cap 13, which width can be seen in FIG. 2.

So that the rinsing cap 13 is provided with additional support by the receptacle 18 during the rinsing process, the force conditions of the overall arrangement are fundamentally improved, so that the elastic deformations that were experienced on machines of the prior art are eliminated, which guarantees a secure preservation of the seal between the O-ring 19 that is located inside the bell 16 and the rinsing cap 13.

Because the forward receptacles 18 of the rinsing caps 13 circulate with the carousel of the can-filling machine, it can occur with certain geometric dimensions of the components that the receptacles project into the path of the cans 15 in the carousel of the filling machine, in particular in the vicinity of the can inlet and outlet.

To substantially eliminate or minimize problems of this type, in one particularly advantageous development, the receptacles 18 are realized so that they can be placed in a position between a non-engaged position and an engaged position.

For example, the receptacles 18 can be realized so that they can pivot around a horizontal axis, so that the receptacles 18, after the completion of the rinsing process, can be pivoted into the non-engaged position, and thereby not interfere with the entry and exit of the cans.

The pivoting movements of the receptacles 18 are preferably controlled by means of a cam or curved-track mechanism in which, for example, a pivoting lever 20 transmits the movements specified by the curved track to the receptacle 18.

However, the pivoting movement of the receptacles 18 can also be effected in a different manner, e.g. by means of open-loop or closed-loop controlled stepper motors, servomotors or synchronous motors. FIG. 1B shows a drive mechanism 50 used to control the pivoting movement of the receptacles 18, and according to at least one possible embodiment may comprise an open-loop or closed-loop controlled stepper motor, servomotor or synchronous motor.

In an additional configuration, the components of the filler valve are realized so that the receptacle 18 does not interfere with the entry or exit of the cans in spite of the fact that the receptacle 18 is immovable.

FIG. 1C shows the rinsing cap 13 in a radially inner, non-engaged position A, and FIG. 1D shows the rinsing cap 13 in a radially outer, engaged position B. The movement from one position to the other can be controlled in a known manner by means of a curved track control system 14, for example.

FIG. 2 shows the guides 17 for the rinsing caps 13 in a radially inner position according to at least one possible embodiment.

As illustrated in FIGS. 3 and 4, for this purpose the invention teaches that the bell 16 is realized so that it can execute an expanded reciprocating movement.

During the normal filling of the cans 15, the bell 16 executes only a normal reciprocating movement h, which is sufficient to seal the cans 15 and release them again. To rinse and/or clean the filling element, the bell 16 executes a large reciprocating movement H which clears the path of the rinsing cap 13 so that the rinsing cap can enter into a functional connection with the receptacle 18.
