Description

FILLING DEVICE The present invention relates to a filling device for filling an article with a pourable product, in particular a pourable food product.

In particular, the filling device according to the present invention is adapted to perform a "hot" filling, that is, to fill the articles with a pourable food product at a temperature higher than the ambient temperature, for example 80 degrees centigrade.

This type of filling is generally used with especially perishable pourable products, for example energy drinks, to which a significant amount of preservative can not be added.

The filling device according to the present invention is also adapted to fill the article with a pourable carbonated product, i.e., a product containing dissolved carbon dioxide, at room temperature, i.e., at a temperature in the range of 4. and 22 degrees Celsius.

Filling machines are known, which comprise a filling station fed with empty articles and adapted to provide articles filled with the 52-877-13 pourable food product.

The filling station substantially comprises a carousel-like conveyor that rotates about an axis of rotation, a tank containing the pourable food product and carbon dioxide, and a plurality of filling devices supported by the carousel in a radially external position with with respect to the axis of rotation of the carousel.

In more detail, the carousel is provided with a plurality of support elements for respective articles provided for arranging the filling mouths of the respective articles in a lower position with respect to the respective filling devices and for moving the articles along a circumferential arc path around said axis of rotation integrally with the filling devices.

Filling devices are known, for example, from US patent application 2010/0071802, which are connected to the carousel and can fill the articles with a hot pourable food product and fill the articles with a pourable carbonated food product at room temperature .

More in detail, the filling devices described in said application comprise: - a first line for fluids connected to 52-877-13 a lower portion of the tank and having a pour opening facing the filling mouth of the respective article; a shutter movable between an open position in which an opening is defined with the first line for fluids and a closed position in which blocks a section of the first line for fluids; a first conduit housed in the article to be filled; a first chamber connected fluidly to the conduit; Y a second line for fluids, which fluidly connects the first conduit with the first chamber.

Filling devices of the known type also include: a second chamber connected fluidly, on one side, with a heat generator and a pump, and on the other side with a portion of the first fluid line disposed downstream of the tank and upstream of the section blocked by the shutter; Y a first valve movable between an open or closed position in which it allows or avoids, respectively, the flow of the pourable product from the portion of the first line for fluids disposed 52-877-13 upstream of the section closed by the obturator towards the second chamber.

When the shutter is arranged in the open position, the pourable product flows along the first line for fluids within the article and at the same time the gas contained in the article returns, by means of the first conduit and the second chamber, in the tank.

In particular, the second line for fluids essentially comprises: a second conduit connected fluidly to the first chamber; third and fourth conduits connected both fluidly to the first conduit; a fifth conduit connected fluidly to the second conduit and having a regulator; a second valve movable between an open position and a closed position in which it allows or avoids, respectively, the fluid connection of the third and second conduits; Y a third valve movable between an open position and a closed position in which it allows or avoids, respectively, the connection fluidly between the fourth and fifth conduits.

In other words, the first chamber is connected to the first conduit by means of two trajectories 52-877-13 incidents with each other in the second conduit.

More precisely, the first path comprises the third and second conduits and is controlled by the second valve while the second path comprises the fourth, fifth and second conduits and is controlled by the third valve.

In the event that the article is to be filled with a carbonated product, the second valve is moved to the respective open position while the obturator and the first valve are held in the respective closed position.

Then a pressurization operation of the article is carried out. This operation is carried out by also moving the third valve in the respective open position. In this way, carbon dioxide flows from the tank to the first chamber, and from there, through the second line for fluids, it reaches the first conduit and then the article.

Once the pressurization step is completed, the plug moves to the open position and a high speed filling of the article is performed.

During the high-speed filling stage, the gas leaving the article flows through the first conduit and flows partially along the third and 52-877-13 second conduits to the first chamber and partially along the fourth and fifth conduits until it reaches the second conduit.

Then, the second valve moves to the respective closed position and a low speed filling stage is carried out. In fact, once the second valve is disposed in the closed position, the gas leaving the article can reach the second conduit only by means of the fourth and fifth conduits, which have a regulator.

At the end of the low speed filling stage, the shutter is placed in the closed position.

In order to fill with the hot pourable product, the components of the filling device must be kept warm when the operation of the filling machine is interrupted.

For this purpose, the filling devices shown in the aforementioned patent application also allow the circulation of the hot pourable product between the first fluid line, the second chamber, the heat source and the tank.

When the operation of the filling machine is interrupted, the first valve moves to the respective open position and the shutter is held in the respective closed position. In this way, the product 52-877-13 The pourable is recirculated between the first fluid line, the second chamber and the tank, and is maintained at the desired temperature by means of the heat source.

In the sector, the need is felt to provide filling devices capable of filling articles with both a hot pourable product and a carbonated product, which are particularly simple to manufacture.

The need to reduce the risk that especially sensitive pourable products are contaminated by the gas that leaves the article, during its filling stage, is also perceived in the sector.

The aforementioned object is achieved by means of the present invention because it relates to a filling device as defined in claim 1.

The present invention therefore relates to a filling device as defined in claim 11.

Hereinafter, two preferred embodiments will be described for a better understanding of the present invention, by means of a non-limiting example and with reference to the accompanying drawings, in which: Figures 1 to 4 show a cross section of a first embodiment of a device 52-877-13 filling according to the present invention, in respective operation stages; Figures 5 to 8 show a cross section of a second embodiment of a filling device according to the present invention, in respective operation stages; Y Figure 9 shows diagrammatically a filling machine incorporating the filling device of figures 1 to 4 or figures 5 to 8.

With reference to Figure 9, the number 1 indicates a filling machine limited to a station for filling articles 2 with a pourable food product.

In particular, the filling station is adapted to fill articles 2 with a pourable product, in particular a pourable food product, at a high temperature, for example 80 degrees centigrade or with a carbonated product, ie in which dioxide is dissolved. carbon at room temperature.

The term ambient temperature indicates a temperature in the range between 4 and 22 degrees centigrade.

In particular, the product is a food product and could be an energy drink.

In more detail, the filling station essentially comprises: 52-877-13 a carousel 3 that rotates about an axis A, which is vertical in the shown case, along a circular path P; a plurality of filling devices 10 adapted to fill respective articles 2 with the pourable food product and supported by a peripheral edge external to the axis? from carousel 3; an input conveyor 4, in particular a star wheel, feeding the carousel 3 with articles 2 to be filled, in a station I of the path P; Y an output conveyor 5, in particular a star wheel, fed by the carousel 3 with articles 2 filled with the pourable product, in a station O of the path P.

More precisely, the trajectory P comprises: a working segment R extending from station I to station 0; Y a return segment S extending from the input station O to the input station I.

The conveyor A is movable along a circular path Ql tangent to the path P, at station I.

The conveyor 5 is movable along a length of 52-877-13 circular trajectory Q2 tangent to trajectory P, at station 0.

The filling machine 1 also comprises. { Figures 1 to 4): a tank 6 which is fixed with respect to axis A and is common to all filling devices 10 and contains the pourable food product and carbon dioxide; Y a plurality of tanks 7 associated with the respective filling devices 10, able to rotate about the axis A integrally with the respective filling devices 10 and fluidly connected with the tank 6.

Each article 2 comprises: a mouth 8 adapted to allow the filling of the article 2 by means of the filling machine 1 and the pouring of the food product of the article 2; Y a bottom wall (not shown) opposite the mouth 8.

Article 2 in the case shown is a container made of glass, plastic or cans.

For simplicity, the following description will refer only to a device 10, in relation to the tank 7 and in relation to the article 2, because the devices 10 are identical to each other. 52-877-13 The device 10 substantially comprises: a structure 11 fixed to the carousel 3; a fluid line 12 defined by the structure 11 and comprising, on its opposite sides, an inlet mouth 13 connected to the tank 7 and a pouring opening 14, which is defined by the structure 11 and oriented towards the mouth 8 of Article 2; a shutter 15 displaceable parallel to the axis B within a line for fluids 12 and movable between an open position (shown in figure 2) in which it allows the fluid connection between the mouth 13 and the opening 14 and a closed position (shown in FIG. Figures 1, 3 and 4) in which it avoids the fluid connection between the mouth 13 and the opening 14.

In more detail, the obturator 15 comprises, on the side of the opening 14, a conical end portion 14 and a conical end portion 16 having an axis B.

The structure 11 also comprises a bell element 17 fixed with respect to the axis B and defining an annular opening 14.

The terminal portion 16 is in contact with a section 19 of the element 17 when the shutter 15 is in the closed position, to block the opening 14.

Differentially, the terminal portion 16 rises 52-877-13 and, in this manner, it is spaced along the axis B of the bell element 17, when the shutter 15 is in the open position to allow the flow of the pourable product through the opening 14.

More precisely, the obturator 15 is elastically filled by means of a spring 18 towards the respective closed position and is displaceable, for example by pneumatic operating means, towards the open position.

In the case shown, the spring 18 is helical and extends along the axis B.

Structure 11 further defines: a duct 20 having an end 21 housed in the mouth 8 of the article 2, during a stage of filling the article 2; a chamber 25 fluidly connected to the conduit 6; Y a line for fluids 22 extending between a mouth 23, opposite the end 21, of the conduit 20 and the chamber 25.

The conduit 20 is at least partially housed within a cylindrical element 24 having an axis B. The spring 18 is fixed to the element 24, on the side opposite the conduit 20, and to the obturator 15.

The device 10 also comprises a valve 52-877-13 26 interposed along the line for fluids 22 and movable between: an open position (FIGS. 1 and 2) in which the conduit 20 and the chamber 25 fluidly connect; Y a closed position (FIGS. 3 and 4) in which it avoids the fluid connection between the conduit 20 and the chamber 25.

Advantageously, the fluid line 22 defines a single fluid path for an aeriform between the opening 14 and the chamber 25.

In particular, the fluid line 22 is formed by a single conduit 30 extending between the mouth 23 and the chamber 25.

In other words, the aeriform can move between the opening 14 and the chamber 25 only through the conduit 30.

This aeriform is the gas that exits from article 2 through conduit 20 during a stage of filling of article 2 (figure 2).

In the case in which the pourable product is carbonated, this aeriform could be carbon dioxide supplied to article 2 via conduit 20 during a pressurization step of article 2 preceding the filling of article 2 (figure 1). 52-877-13 The device 10 further comprises: a camera 40; a fluid line 41 extending between the chamber 40 and the opening 45 of the fluid line 12 disposed upstream of the section 19 of the bell element 17, advancing along the path of the pourable product from the tank 7 to the opening 14; a fluid line 42 extending between an opening 44 of the fluid line 12 disposed downstream of the section 19 of the obturator 15 against the bell element 17; Y a regulator 49 interposed along the fluid line 42 between the valve 51 and the chamber 40.

In more detail, the chamber 40 selectively connects fluidly to an exhaust 46 at an ambient pressure or to a heat source 39 and to the tank 6.

In other words, the camera 40 is: fluidly connected to exhaust 46 and fluidly isolated from heat source 39 and tank 6; or fluidly connected to the heat source 39 and the tank 6, and fluidly isolated from the exhaust 46.

The device 10 further comprises: 52-877-13 a valve 50 interposed along the line for fluids 41 and movable between an open position (figure 4) or a closed position (figures 1 to 3) in which it allows or prevents, respectively, the pourable product from flowing from the opening 45 to the chamber 40 along the fluid line 41; a valve 51 interposed along the line for fluids 42 and movable between an open position (figure 3) or a closed position (figures 1,2 and 4) in which it allows or prevents, respectively, that the gas contained in the Article 2 flows from the opening 44 to the chamber 40 along the fluid line 41; a flow velocity meter 53 adapted to measure the flow velocity of the pourable product from the tank 7 to the fluid line 12 and which therefore fills the article 2; a control unit 55 (only indicated diagrammatically in FIGS. 1 to 4) configured to move the valves 26, 50, 51 and the shutter 15 between the respective open and closed positions, depending on the operating cycle that the filling device must perform 10 The control unit 55 is also controlled by the flow rate meter 53.

The operation of filling machine 1 is 52-877-13 described below, with reference only to a filling device 10 and a single corresponding article 2.

More precisely, the operation of the filling machine 1 is described hereinafter during a filling cycle of article 2 with a pourable carbonated food product, ie containing dissolved carbon dioxide, at an ambient temperature, i.e. at a temperature in the range of between 4 and 22 degrees centigrade.

During this cycle, the control unit 55 maintains the chamber 40 connected to the exhaust 46 at ambient pressure and prevents (not shown) the fluid connection between the chamber 40 and the heat source 39.

The carousel 3 receives the article 2 to be filled from the conveyor 4 in station I of the path P, and feeds the filled article 2 to the conveyor 5 in station O of the path P.

More precisely, the article 2 is arranged in such a way that the mouth 8 is below the pouring opening 14 of the duct 20 and the duct 20 passes therethrough.

From a condition in which all valves 26, 50, 52 and shutter 15 are maintained by means of control unit 55 in the respective positions 52-877-13 closed, the filling device 10 performs the following operations: pressurization of Article 2 with the introduction of carbon dioxide in Article 2 in order to bring the pressure in Article 2 to a value present in Tank 7 (Figure 1); filling of article 2 with the carbonated product (figure 2); Y depressurization of article 2 (figure 3). In more detail, the control unit 55 moves, during the pressurization step, the valve 26 in the open position in such a way that the carbon dioxide contained in the tank 6 can flow along the line for fluids 22 and the conduit 20, until it reaches the mouth 8 of article 2 (figure 1).

Once the pressurization step is completed, the control unit 55 moves the shutter 15 in the open position against the action of the spring 18. Consequently, the pourable product flows from the fluid line 12 into the article 2. At the same time , the gas contained in article 2 passes through conduit 20 and fluid line 22 until it reaches tank 6 (figure 2).

When the flow rate meter 53 has detected that the correct amount of product has passed 52-877-13 Pourible through the fluid line 12 and therefore has filled the article 2, the control unit 55 moves the obturator 15 towards the closed position, thus interrupting the filling of the article 2 (figure 3).

At this point, the control unit 55 moves the valve 51 to the open position, so that the gas contained in the neck portion of the article flows from the opening 44 and, via the fluid line 42, reaches the chamber 40 and therefore the exhaust 46.

In this way, article 2 is depressurized.

Then, the valve 51 returns by means of the control unit 55 to the closed position and the article 2 filled with the pourable product is removed from the conveyor 5 at the station O and removed from the filling device 10.

Next, a filling cycle of article 2 with a pourable "hot" non-carbonated product - that is, at a temperature higher than the ambient temperature - is limited to the stages in which it differs from the filling cycle of article 2 with a carbonated product previously described.

This "hot" filling cycle differs from the filling cycle described above with a carbonated product because the control unit 55 maintains the 52-877-13 chamber 40 connected to tank 6 and to heat source 39, and at the same time maintains chamber 40 isolated from exhaust 46.

This "hot" filling cycle also differs from the filling cycle described above with a carbonated product because it does not comprise the steps of pressurizing and depressurizing the article 2, respectively, before and after the filling step of article 2. Consequently, the valve 42 is maintained by means of control unit 55 in the closed position, during the filling cycle of article 2 with the pourable product at a temperature higher than room temperature.

Finally, the "hot" filling cycle differs from the filling cycle described above with a carbonated product because, when the filling machine 1 is in an operating stage in which the articles 2 are not full, the pourable product is recirculated between the opening 45, the fluid line 41, the chamber 40, the heat source 39 and the tank 6 (figure 4).

More precisely, with the shutter 15 arranged in the closed position, the control unit 55 places the valve 50 in the open position.

The pourable product then passes through the heat source 39 and is maintained at a temperature higher than the ambient temperature. 52-877-13 When it is necessary to resume filling the article 2, the control unit 55 moves the valve 50 to the closed position.

Then, the control unit 55 places the shutter 15 in the respective open position.

With reference to Figures 5 to 8, the number 10 indicates, overall, a filling device according to a different embodiment of the present invention. The filling device 10 'is smaller than the filling device 10 and will be described hereafter only to the extent that it differs from it; the corresponding or equivalent parts of the filling devices 10 and 10 'will be indicated where possible with the same reference numbers.

In particular, the filling device 10 'differs from the filling device 10 in that it comprises: a chamber 60 'which can be connected fluidly to an exhaust 46' or to a heat source 39 and tank 6; - a fluid line 61 'extending between a segment 43' of the fluid line 22 interposed between the mouth 23 and the valve 26 and the chamber 60 ', and along which a valve 62' intervenes; and a fluid line 41 'extending between the chamber 60' and the opening 45 of the line for 52-877-13 fluids 12, and along which a valve 50 'is interposed.

The operation of the filling device 10 'is similar to the operation of the filling device 10 and differs from it, because, during the filling cycle of the article 2 with a carbonated product at room temperature, the valve 26 is maintained by means of the control unit 55 in the closed position and valve 62 'is placed by control unit 55' in the respective open position (figure 6).

The chamber 60 'is also connected fluidly by means of the control unit 55' to the exhaust 46.

In this way, during the stage of filling the article 2 with the pourable product, the gas leaving the article 2 flows exclusively along the fluid line 61 'to the chamber 60' and the exhaust 46 '.

Consequently, the gas leaving article 2 does not return to tank 6 and does not mix with the pourable product present in tank 6.

According to an alternative configuration of the control unit 55 (not shown), during the filling cycle of the article 2 with a carbonated product at room temperature, the valve 26 is maintained by means of the control unit 55 in the position open and the valve 62 'is placed by the control unit 55' in the 52-877-13 respective closed position.

In this way, during the filling step of article 2 with the pourable product, the gas leaving article 2 flows exclusively along the line for fluids 22 towards chamber 25 and tank 6.

On the other hand, with reference to the filling of the article 2 with a pourable product at room temperature and in a step of stopping the operation of the filling machine 1, the control unit 55 maintains the valves 26, 51 and 62 'in the respective closed positions and places the valve 50 'in the respective open position. The control unit 55 also fluidly connects the chamber 60 'with the heat source 39 (Figure 8).

In this way, in the case of an interruption of the filling step, the pourable product is recirculated between the opening 45, the fluid line 41 ', the chamber 60', the heat source 39 and the tanks 6 and 7.

From an analysis of the characteristics of the device 10, 10 'and in accordance with the present invention, the advantages it allows to obtain are evident.

In particular, the filling devices 10, 10 'make it possible to fill the articles 2 with a pourable non-carbonated product at a temperature higher than the ambient temperature and with a carbonated product at an ambient temperature with a simplified structure. 52-877-13 In particular, the fluid line 22 is formed by a single conduit 30 extending between the mouth 14 and the chamber 25.

Therefore, the filling devices 10, 10 'permit the return of the gas during the filling step of the article 2 or the pressurization of the article 2 before filling it with a gaseous product, with a particularly simple structure with respect to the shown in the known solutions described in the introductory part of the present description.

Additionally, the filling device 10 'is particularly suitable for filling articles 2 with particularly perishable pourable products.

In fact, the gas leaving the article 2 is transported along the fluid line 61 'to the chamber 60' and the exhaust 46 '. Therefore, this gas does not mix with the pourable product present in tank 6.

This particularly prevents perishable products from being contaminated when stored in tank 6, by the gas leaving article 2, during its filling stage.

Finally, it is evident that modifications and variations can be made to the filling valve 10, 10 ', without departing from the scope of protection of the claims. 52-877-13
