Description

DESCRIPTION

Dispensing device for a filling machine and machine comprising said devices

The present invention refers to the field of equipment for the automated transfer of liquids from a large capacity container to several smaller individual containers, particularly food liquids, and particularly wines, beers, juices or similar non-carbonated beverages. or foamy. Extraction equipment of this type (generally by gravity and under slight pressure or depression) can be associated on the same frame with a corker to constitute an automatic bottling group.

The applicant has been manufacturing and marketing this type of equipment for many years, in particular under the names FIAMAT, COMET and GALAXY.

In this general context of transfer equipment, the present invention aims at an improved dispensing (or extractor) device, as well as a container-filling machine comprising said devices.

Numerous embodiments of dispensing or filling devices are already known which allow the level filling of containers, in particular bottles or the like, with a liquid food product, in particular wine or the like, from a main or central container of the vat type or similar.

Devices of this type typically include:

- a hollow body that forms an intermediate tank or supply conduit, fluidly connected to said tank and that is extended at its bottom with a first tube (defining an axial direction) configured to be able to be introduced into a container to be filled through an opening of the latter, for example at the level of a neck,

- a second tube that extends coaxially and internally through the hollow body and the first tube and that defines with the first tube a nozzle with an annular cross-sectional passage that allows fluid communication between said hollow body and a container to be filled, being able to open and close this passage selectively by means of the axial displacement of the second tube with respect to the first,

- tight contact means configured to tightly seal the opening of the container to be filled around the nozzle that passes through said opening and to determine, in cooperation with said first and second tubes, the filling level of said container,

- drive means to control the axial positioning of the second inner tube, said means being located above the hollow body, on the other side of the nozzle, and

- a set of control valves in fluid communication respectively with the hollow body, the second tube or the container to be filled in order to inject into it or discharge from it at least one type of gas or air, an injected gas or an excess of liquid.

Through document EP 1995208 a filling machine with several dispensing devices is known, in which the inner and outer tubes of the filling nozzle move simultaneously with respect to the vat and the sealed contact means fixed to the latter , to set the fill level.

To this end, this EP document provides for a complex arrangement of the transmission means and the drive means, as well as specific mechanical connections between the two tubes.

Also known from EP 2958851 (WO 2014/170812) and EP 2903929 is an isobaric filling machine with various dispensing devices, in which the filling nozzle (with an annular duct formed between the two concentric inner and outer tubes ) is provided at its lower end with two closure elements, namely a first for the annular duct (seal mounted on the lower end of the inner tube) and a second for the inner tube of the filling nozzle (seal mounted on the lower end of a sliding inner rod). This results in a complex construction of the nozzle, which is difficult to clean and requires two linear actuators for the different drives of the two closure elements mentioned above.

In addition, the valves that control the flow of gas between the bottle to be filled, the tank, the atmosphere, and the neutral gas tanks are grouped according to a linear configuration in a block arranged laterally and close to the bottom outlet of the the nozzle, being fixed to the machine. This results in two separate supply hose bundles, one for the actuators at the top and one for the valves at the bottom.

Finally, the assembly/disassembly and maintenance of the different components that make up the dispensing devices of these two EP documents are a priori tedious.

Finally, by means of EP 2236454 an isobaric filling machine with various dispensing devices is also known, in which the first outer tube is provided with an inner tubular clapper valve and in which the second inner tube can be adjusted in height to set the fill level of the bottles. For the adjustment of this level, each dispensing device comprises three different drive means, which results in an extremely complex overall construction and kinematics.

The main objective of the invention is to overcome the drawbacks of the known solutions mentioned above and offer a less complex construction of a dispensing device and a filling machine, and whose number of moving parts or components is limited, especially with regard to to parts or components in contact with fluids (gases and liquids).

To this end, the invention aims at a dispensing device of the type presented above and characterized in that it comprises a fluid management block that groups valves fluidly connected to the second inner tube and that has at least one discharge valve to place the container to be filled at negative pressure or atmospheric pressure, at least one valve to inject neutral or inerting gas, and at least one valve to establish fluid communication with the hollow body, this functional block being mounted on the upper part of said body hollow, is traversed by the second tube and supports the actuation means of the latter, and because said hollow body, together with the first and second tubes mentioned above, the fluid management functional block and the actuation means of the second tube Together they form a structural unit fixed rigidly on or inside the tank.

Figs. 2 to 9 show, for some only partially, a dispensing device 1 for a machine 2 for filling containers 3, in particular bottles or the like, with a liquid 4, in particular with still, sparkling or similar wine, to from a vat 5 or a similar storage container that is part of said machine 2.

This device 1 comprises:

- a hollow body 6 that forms an intermediate tank or supply conduit, fluidly connected to said tank 5 and that is extended in its lower part by a first tube 7 that defines an axial direction DA and is configured to be able to be inserted into a container to be filled 3 through an opening 3' of the latter, for example, at the level of a neck 3",

- a second tube 8 that extends coaxially and internally through the hollow body 6 and the first tube 7 and that defines with the first tube 7 a nozzle 9 with a passage 9' of annular cross section that allows fluid communication between said body hole 6 and a container 3, it being possible to open and close said passage 9' selectively by means of the axial displacement of the second tube 8 with respect to the first tube 7

- leaktight contact means 10 configured to tightly seal the opening 3' of the container to be filled 3 around the nozzle 9 passing through said opening 3' and determine, in cooperation with said first and second tubes 7, 8, the filling level of said container 3,

- drive means 11 to control the axial positioning of the second inner tube 8, said means 11 being located above the hollow body 6, on the other side of the nozzle 9,

- a set of control valves 12 to 16 in fluid communication respectively with the hollow body 6, the second tube 8 or the container to be filled 3 to inject at least one type of gas or air into it or to discharge air from it, an injected gas or excess liquid 4 (air injection/discharge when pressurized to atmospheric pressure).

According to the invention, said device 1 also comprises a fluid management block 17 that groups valves 12 to 15 fluidly connected to the second inner tube 8 and having at least one discharge valve 12; 14 to put the container 3 to be filled at negative pressure or atmospheric pressure, at least one valve to inject neutral or inerting gas 13, and at least one valve 15 to establish fluid communication with the hollow body 6. In addition, this functional block 17 which is mounted on the upper part of said hollow body 6, is traversed by the second tube 8 and supports the drive means 11 of the latter. In addition, said hollow body 6 with the first and second tubes 7, 8, the fluid management functional block 17 and the drive means 11 of the second tube 8 together form a structural unit rigidly fixed on or inside the tub 5.

Thanks to the construction proposed by the invention, the dispensing device 1 has a single actuation means 11 and a single moving part (the second inner tube 8), and this with a small range of movement and between two extreme opening and closing positions. closing.

Furthermore, by grouping most of the fluid control components (valves 12-15) into a single functional block 17, the overall size and complexity of the arrangement is greatly reduced. In addition, the modularity resulting from this regrouping facilitates the maintenance and replacement of said components, since it is only necessary to disassemble the block 17 in one piece and replace or repair it if necessary.

According to a first embodiment of the invention, not shown in the attached figures, the modular structural unit formed by the hollow body 6 that forms the supply conduit, the functional block 17 and the drive means 11 can be configured to be mounted within the tub 5 and extend therethrough.

The tub then advantageously has a generally linear shape, with integrated nozzles 9 arranged along a rectilinear arrangement.

According to a second preferred embodiment, as shown in the attached figures, the modular structural unit composed of the hollow body 6 that forms the intermediate tank, the functional block 17 and the drive means 11 is mounted on the outside of the vat 5, being connected preferably only by means of fluid connection 18, 18' (rigid tubes) of the said hollow body 6 with the said vat 5, which can be displaced in the axial direction DA of the nozzle 9 with respect to the means watertight contact 10.

In this way, due to its rigid connection with a central vat 5 (for example, circular - see Figs. 1A and 1B), all the dispensing devices 1 of a filling machine 2 move simultaneously in the two forms of realization and determination of the fill level for the different devices 1 requires a single adjustment on the machine 2 and not an individual adjustment for each device 1.

The detailed constitution of the different valves 12 to 16, which is apparent to a large extent from the figures, will not be detailed further, since these components are known to the person skilled in the art. As an alternative to the valve constructions shown in the accompanying figures, these valves 12 to 16 can also be of another type, for example diaphragm.

Advantageously and in order to limit the number of parts and the cost of production, the connection means of the tank 5 with the intermediate tank 6 comprise two rigid conduits 18, 18' connected, with a mutual offset in the axial direction DA of the first tubes. and second 7, 8, on the one hand, to the intermediate tank 6, preferably elongated in this direction DA. These two conduits 18, 18' are integral parts, on the opposite side, of a fixing plate 19 to the vat 5, the lower conduit 18 being used for the circulation of the liquid 4 by gravity, and where appropriate under gas pressure, and the upper conduit 18' being used for gas reflux.

In the event of replacement or maintenance of a device 1, it will therefore suffice to detach the plate 19 in question to recover it in its entirety, with the exception of the watertight contact means 10.

According to a preferred embodiment, as shown for example in Figs. 2, 3, 4B, 5, 7 and 8, the fluid management block 17 has a central chamber 20 in fluid communication, on the one hand , with the second tube 8 that crosses it and, on the other hand, with each one of the control valves 12 to 15 integrated in said block 17. In addition, these different valves 12 to 15 are arranged in the block 17 in a circle around said second tube 8 and said central chamber 20.

As deduced from Figs. 4B, 7 and 8 in particular, the second tube 8 can have perforations 8" in its wall for communication between its internal passage and said central chamber 20.

According to a simple, compact and integrated design variant, it can be provided that the fluid management block 17 consists of two complementary components 17', 17", namely:

- on the one hand, a lower part 17' that incorporates the seats 12' to 15' (12', 13', 14', 15') of the control valves 12 to 15 integrated in said block 17 as well as parts 17" 'of fluid circulation lines connected respectively to the external environment, to the second tube 8 and to the intermediate tank 6, advantageously closing this lower part 17', the intermediate tank 6 is extended to the other side of its lower end by means of the first tube 7 , and

- on the other hand, an upper part 17" that has the control means 12" to 15" (12", 13", 14", 15") of said valves 12 to 15 and carries the actuation means 11 (single) for translational control of the second inner tube 8 in the axial direction DA.

As shown by way of example in Figs. 6, 8 and 9, the drive means 11 of the second tube 8 preferably consist of an actuator cylinder configured to move the second tube 8, provided at its lower end with a closure element seal 8' of the annular passage 9' at its lower outlet, between a lowered opening position and a raised closed position of the latter, along the axial direction DA. Eventually, the second tube 8 can be made up of several tubular parts assembled together and be connected to the actuator cylinder 11 by means of a connection piece.

Like the control means 12" to 15" of the control valves 12 to 15, the actuating cylinder 11 is advantageously pneumatic in nature, to standardize the energy source. However, a hydraulic or electric actuator cylinder 11 can also be provided, as for the control means of the aforementioned valves.

Preferably, the mechanical connection between the second inner tube 8 and the drive actuator cylinder 11 is formed by a locking means 11', the unlocking of which allows the removal of said inner tube 8.

According to a feature of the invention, and as shown for example in Figs. 3A, 4A, 5A and 6, the sealed contact means 10, traversed by the nozzle 9', have at least one valve 16 to control the circulation in a part of the fluid circulation line 10' configured to connect, ending at the outer face of the nozzle 9 that extends through its opening 3', a container to be filled 3 either with the external environment or with a neutral gas source or pressurized blanketing, such as CO2 or N2.

In particular, this line part 10' is used to form a flow line for fluids through a container 3 in combination with the second inner tube 8.

In order to be able to control the pressure of the gas in the container 3, the sealed contact means 10 also have a pressure sensor 21 configured to measure the pressure in the part of the gas circulation line 10'.

According to a practical example of construction, as shown in Figs. 2, 3, 5, 6 and 9, the sealed contact means 10 comprise a cylindrical body 22 that is traversed by the nozzle 9 and that has a first sealing gasket 22' which extends outwardly around the first tube 7 and a second gasket 22" intended to make contact under pressure around the opening 3' of a container 3, and the part of the circulation line 10' is integrated into a support arm 10" that carries the cylindrical body 22, the control valve 16 and, if necessary, the pressure sensor 21, and opens between the first and second joints 22', 22" mentioned above, fixing said sealed contact means 10 the filling level in cooperation with the nozzle 9.

As shown in Fig. 2, the cylindrical body 22, configured to form a tight plug around the nozzle 9 and the opening 3' of the container 3 that receives it, can be connected to the support arm 10" in a detachable manner. , for example, by means of a tight connection by adjustment, clamping or similar, with locking by means of a 10" latch.

The latter makes it possible to detach the body 22 from the arm 10" and disassemble it during the removal of the structural unit 11/6/9.

The dispensing device 1 can also further comprise a means to center and retain 23 a container 3 during filling, for example, in the form of a centering cone whose purpose is to make contact at the base of the neck 3" of a bottle 3, these means 23 sliding freely along and at a distance from the nozzle 9, below the watertight contact means 10, and being adhered to a guide 23' connected to the hollow body 6 (with the capacity to move along the axis GIVES).

The invention also refers, as shown in Figs. 1A and 1B, to a machine 2 for filling containers 3, in particular bottles or the like, with a liquid 4, for example an alimentary liquid of the still wine type, sparkling wine or similar, from a tank 5 or similar.

This machine 2 essentially comprises a frame 2' that supports said vat 5 with the liquid 4, under the pressure of a neutral or non-neutral gas, and, furthermore, on the one hand, means for supplying the empty containers 3, to position said containers 3 for the purpose of filling and unloading the filled containers 3 and, on the other hand, displacement means in vertical translation of the tub 5. This machine 5 is also equipped with several dispensing devices 1, arranged circumferentially around (Fig. 1) or along at least one side of said tub 5, or even mounted on said tub 5.

According to the invention, the dispensing devices of this machine 2 consist of devices 1 of the type described above, and the watertight contact means 10 are also installed on the frame 2' to cooperate each with a corresponding dispensing device 1, being able to set in position along the axial direction DA of the associated dispensing device 1.

Preferably, the control valves 12 to 16 are of the default closed type (eg spring loaded - see drawings). In the same way, the actuating means 11 is forced in a default position such that the annular channel 9' is closed in the absence of a positive opening force (in the example shown in the drawings, the actuating cylinder 11 pushes the inner tube 8 downwards to release the lower opening of the channel 9', against the elastic force of a compression spring).

Furthermore, advantageously the tank 5 is under the pressure of an inert gas and the level N of liquid 4 in this tank 5 is located between the openings that open into the conduits 18 and 18' (see Fig. 3A).

By way of non-restrictive example, a filling cycle in a device 1 of a bottle-type container 3 can comprise the following stages, after placing the bottle 3 under the dispensing device 1 in question (Fig. 3A, 3B):

- stage 1: bringing the opening 3' of the neck 3" into contact with the joint 22' of the sealed contact means 10, after the introduction of the neck into the centering and retention means 23 and the simultaneous introduction of a part bottom of the nozzle 9 in the neck 3" in a position corresponding to the filling level set by the distance between the lower end of the nozzle and the area of contact between the gasket 22" and the bottle 3 (see Fig. 5 6 );

- stage 2: creation of a relative vacuum in the bottle 3 through the inner tube 8 by opening the valve 12 connected to a vacuum source;

- stage 3: injection of inert gas (for example, carbon dioxide or nitrogen) into the bottle 3 through the valve 13 (connected to a corresponding source) and the inner tube 8;

- stage 4: creation of a relative vacuum in the bottle 3 as in stage 2;

- stage 5: pressurization of the filling circuit and the bottle 3 with carbon dioxide or nitrogen by opening the valve 15 that connects the tank 5 and the intermediate tank 6 (which are subjected to an atmosphere of pressurized inert gas) to the tube 8 bottle 3 open interior;

- stage 6: activation of the drive means 11 that cause the opening of the annular passage 9' by moving the inner tube 8 downwards (Fig. 8 and 9): circulation of the liquid 4 contained towards the tank 5 through the conduit 18 to the buffer tank 6 and then through the annular passage 9' to the bottle 3, and simultaneous reflux of the inerting gas present in the bottle 3 through the inner tube 8 and the valve 15 towards the upper part of the intermediate tank 6 (and through the conduit 18' towards the tank 5);

- stage 7: at the end of filling: closure of the annular passage 9' and leveling of the liquid 4 in the bottle 3 by injecting inerting gas through the valve 16 of the sealed contact means 10: the quantity of liquid 4 located above the lower outlet of the inner tube 8 through this tube and through the valve 15 towards the intermediate tank 6, immediately closing said valve 15 to isolate the pressure filling circuit as soon as all the liquid 4 unloaded has returned to buffer repository 6;

- stage 8: pressurize bottle 3 to atmospheric pressure by operating valve 14.

These different steps are carried out simultaneously for most or even all of the dispensing devices 1 installed in a filling machine 2 according to the invention.

These different stages are carried out under the control of a control unit, such as a programmable controller or the like, which takes into account, in particular, the pressures measured at the level of the sensors 21 of the different devices 1. It should also be noted that during the stages of pressurization of the container 3, the valve 16 can be used advantageously as a pressure safety valve.

Of course, the invention is not limited to the embodiment described and represented in the attached drawings. Changes remain possible, in particular from the point of view of the constitution of the various elements, without however departing from the field of protection of the invention as defined in the appended claims.
