- control unit 55 maintains chamber 40 connected to exhaust 46 at an ambient pressure and prevents (not shown) the fluidic connection between chamber 40 and heat source 39.
- Carousel 3 receives article 2 to be filled from conveyor 4 at station I of path P, and feeds filled article 2 to conveyor 5 at station O of path P.
- article 2 is arranged so that mouth 8 is below pouring opening 14 of duct 20 and duct 20 passes therethrough.
- filling device 10 From a condition in which valves 26, 50, 51 and shutter 15 are all maintained by control unit 55 in respective closed positions, filling device 10 performs the following operations:

- This "hot” filling cycle differs from the previously disclosed filling cycle with a carbonated product in that control unit 55 maintains chamber 40 connected to tank 6 and to heat source 39, and maintains at the same time chamber 40 isolated from exhaust 46.
- This "hot” filling cycle also differs from the previously disclosed filling cycle with a carbonated product by not comprising the steps of pressurising and depressurising article 2 respectively before and after the step of filling article 2. Accordingly, valve 42 is maintained by 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.
- the "hot" filling cycle differs from the previously disclosed filling cycle with a carbonated product in that, when filling machine 1 is in an operative step in which articles 2 are not filled, the pourable product is recirculated between opening 45, fluidic line 41, chamber 40, heat source 39 and tank 6 ( Figure 4 ).
- control unit 55 arranges valve 50 in the open position.
- the pourable product thus passes through heat source 39 and is maintained at a temperature higher that room temperature.

- filling device 10' differs from filling device 10 by comprising:
- filling device 10' is similar to the operation of filling device 10 and differs therefrom, in that, during the filling cycle of article 2 with a room temperature carbonated product, valve 26 is maintained by control unit 55 in the closed position and valve 62' is arranged by control unit 55' in the respective open position ( Figure 6 ).
- Chamber 60' is also connected fluidically by control unit 55' with exhaust 46'.
- control unit 55 during the filling cycle of article 2 with a room temperature carbonated product, valve 26 is maintained by control unit 55 in the open position and valve 62' is arranged by control unit 55' in the respective closed position.
- control unit 55 maintains valves 26, 51 and 62' in the respective closed positions and arranges valve 50' in the respective open position.
- Control unit 55 fluidically also connects chamber 60' with heat source 39 ( Figure 8 ).
- the pourable product is recirculated between opening 45, fluidic line 41', chamber 60', heat source 39 and tanks 6 and 7.
- filling devices 10, 10' allow with a simplified structure to fill articles 2 both with a pourable non carbonated product at a temperature higher than room temperature and with a carbonated product at a room temperature.

Description
- The present invention relates to a filling device for filling an article with a pourable product, in particular a pourable food product according to the preamble of claim 1.
- In particular, the filling device according to the present invention is adapted to perform a "hot" filling, i.e. to fill the articles with a pourable food product at a temperature higher than room 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 relevant amount of preservative cannot be added.
- The filling device according to the present invention is also adapted to fill the article with a carbonated pourable product, i.e. a product containing dissolved carbon dioxide, at a room temperature, i.e. at a temperature in the range between 4 and 22 degrees centigrade.
- Filling machines are known, comprising a filling station fed with empty articles and adapted to provide articles filled with the pourable food product.
- The filling station substantially comprises a carousel conveyor rotating about a rotation axis, a tank containing the pourable food product and carbon dioxide, and a plurality of filling devices supported by the carousel in a position radially external with respect to the rotation axis of the carousel.
- In greater detail, the carousel is provided with a plurality of support elements for respective articles provided to arrange filling mouths of respective articles in a lower position with respect to the respective filling devices and to displace the articles along a circumferential arc trajectory about the above said rotation axis integrally to the respective filling devices.
- Filling devices are known, for example from patent application
US2010/0071802 , which are connected to the carousel and can fill the articles with a hot pourable food product and fill the articles with a carbonated room temperature pourable food product. - In greater detail, the filling devices disclosed in the above cited application comprise:
- a first fluidic line connected to a lower portion of the tank and having a pouring opening facing the filing mouth of the respective article;
- a sliding shutter between an open position in which it defines an opening with the first fluidic line and a closed position in which it blocks a section of the first fluidic line;
- a first duct housable within the article to be filled;
- a first chamber fluidically connected with the duct; and
- a second fluidic line, which fluidically connects the first duct with the first chamber.
- The filling devices of the known type also comprise:
- a second chamber fluidically connected, on one side, with a heat generator and a pump, and on the other side with a portion of the first fluidic line arranged downstream of the tank and upstream of the section blocked by the shutter; and
- a first valve displaceable between an open or closed position in which it respectively allows or prevents the flow of the pourable product from the portion of the first fluidic line arranged upstream of the section closed by the shutter towards the second chamber.
- When the shutter is arranged in the open position, the pourable product flows along the first fluidic line within the article and at the same time the gas contained within the article returns, by means of the first duct and the second chamber, within the tank.
- In particular, the second fluidic line essentially comprises:
- a second duct fluidically connected with the first chamber;
- a third and fourth duct both fluidically connected with the first duct;
- a fifth duct fluidically connected with the second duct and having a throttle;
- a second valve displaceable between an open position and a closed position in which it respectively allows or prevents the fluidic connection of the third and the second duct; and
- a third valve displaceable between an open position and a closed position in which it respectively allows or prevents the fluidic connection between the fourth and the fifth duct.
- In other words, the first chamber is connected to the first duct by means of two paths incident to one another in the second duct.
- More precisely, the first path comprises the third and the second duct and is controlled by the second valve while the second path comprises the fourth, the fifth and the second duct and is controlled by the third valve.
- In case the article must be filled with a carbonated product, the second valve is displaced in the respective open position while the shutter and the first valve are maintainer in the respective closed position.
- An operation of pressurisation of the article is subsequently performed. This operation is performed by also displacing the third valve in the respective open position. Thereby, carbon dioxide flows from the tank to the first chamber, and therefrom, by means of the second fluidic line, reaches the first duct and, then, the article.
- Once the pressurisation step is completed, the shutter is displaced in the open position and a high speed filling of the article is performed.
- During the high speed filling step, the gas flowing out from the article flows through the first duct and partially flows along the third and the second duct towards the first chamber and partially along the fourth and fifth duct until it reaches the second duct.
- Subsequently, the second valve is displaced in the respective closed position and a low speed filling step is performed. As a matter of fact, once the second valve is arranged in the closed position, the gas flowing out from the article can reach the second duct only by means of the fourth and the fifth duct, which has a throttling.
- At the end of the low speed filling step, the shutter is arranged in the closed position.
- In order to perform the filling with the hot pourable product, the components of the filling device must be maintained hot when the operation of the filling machine is interrupted.
- For this purpose, the filling devices shown in the above cited patent application also allow the circulation of the hot pourable product between the first fluidic line, the second chamber, the source of heat and the tank.
- When the operation of the filling machine is interrupted, the first valve is displaced in the respective open position and the shutter is maintained in the respective closed position. Thereby, the pourable, product recirculates between the first fluidic line, the second chamber and the tank, and is maintained at the desired temperature by the heat source.
- The need is felt in the sector to provide filling devices capable of filling the articles both with a hot pourable product and with a carbonated product, which are particularly simple to manufacture.
- The need is also felt in the sector to reduce the risk that especially sensitive pourable products are contaminated by the gas flowing out from the articles, during the filling step thereof.
- It is an object of the present invention to provide a filling device, designed to meet at least one of the above-identified requirements.
US2010/0071802 discloses a filling device, according to the preamble of claim 1 and claim 6. - The aforementioned object is achieved by the present invention as it relates to a filling device as defined in claim 1 and in

Control unit 55 is also controlled byflow rate measurer 53. - The operation of filling machine 1 is disclosed hereinafter, with reference to only one
filling device 10 and a singlecorresponding article 2. - More precisely, the operation of filling machine 1 is disclosed hereinafter during a filling cycle of
article 2 with a carbonated pourable food product, i.e. containing dissolved carbon dioxide, at a room temperature, i.e. a temperature in the range between 4 and 22 degrees centigrade. - During this cycle,
control unit 55 maintainschamber 40 connected to exhaust 46 at an ambient pressure and prevents (not shown) the fluidic connection betweenchamber 40 andheat source 39. - Carousel 3 receives
article 2 to be filled from conveyor 4 at station I of path P, and feeds filledarticle 2 to conveyor 5 at station O of path P. - More precisely,
article 2 is arranged so that mouth 8 is below pouringopening 14 ofduct 20 andduct 20 passes therethrough. - From a condition in which
valves shutter 15 are all maintained bycontrol unit 55 in respective closed positions, fillingdevice 10 performs the following operations: - pressurisation of
article 2 with the introduction of carbon dioxide withinarticle 2 in order to bring the pressure inarticle 2 to a value present in tank 7 (Figure 1 ); - filling
article 2 with the carbonated product (Figure 2 ); and - depressurising article 2 (
Figure 3 ). - In greater detail,
control unit 55 displaces, during the step of pressurisation,valve 26 in the open position so that carbon dioxide contained intank 6 can flow alongfluidic line 22 andduct 20, until it reaches mouth 8 of article 2 (Figure 1 ). - Once the step of pressurising is completed,
control unit 55 displaces shutter 15 in the open position against the action ofspring 18. Accordingly, the pourable product flows fromfluidic line 12 withinarticle 2. At the same time, the gas contained inarticle 2 passes throughduct 20 andfluidic line 22 until it reaches tank 6 (Figure 2 ). - When
flow rate measurer 53 has detected that the correct amount of pourable product has passed throughfluidic line 12 and thus has filledarticle 2,control unit 55 displaces shutter 15 in the closed position, thus interrupting the filling of article 2 (Figure 3 ). - At this point,
control unit 55 displacesvalve 51 to the open position, so that the gas contained in the neck portion of the article flows out from opening 44 and, by means offluidic line 42, reacheschamber 40 and thereforeexhaust 46. - Thereby,
article 2 is depressurised. - Then,
valve 51 is returned bycontrol unit 55 to the closed position andarticle 2 filled with the pourable product is withdrawn from conveyor 5 at station O and moved away from fillingdevice 10. - A filling cycle of
article 2 with a non-carbonated "hot" - i.e. at a temperature higher than room temperature - pourable product is disclosed hereinafter, limitedly to the steps in which it differs from the filling cycle ofarticle 2 with a previously disclosed carbonated product. - This "hot" filling cycle differs from the previously disclosed filling cycle with a carbonated product in that
control unit 55 maintainschamber 40 connected totank 6 and to heatsource 39, and maintains at thesame time chamber 40 isolated fromexhaust 46. - This "hot" filling cycle also differs from the previously disclosed filling cycle with a carbonated product by not comprising the steps of pressurising and
depressurising article 2 respectively before and after the step of fillingarticle 2. Accordingly,valve 42 is maintained bycontrol unit 55 in the closed position, during the filling cycle ofarticle 2 with the pourable product at a temperature higher than room temperature. - Finally, the "hot" filling cycle differs from the previously disclosed filling cycle with a carbonated product in that, when filling machine 1 is in an operative step in which
articles 2 are not filled, the pourable product is recirculated betweenopening 45,fluidic line 41,chamber 40,heat source 39 and tank 6 (Figure 4 ). - More precisely, with
shutter 15 arranged in the closed position,control unit 55 arrangesvalve 50 in the open position. - The pourable product thus passes through
heat source 39 and is maintained at a temperature higher that room temperature. - When the filling of
article 2 needs to be resumed,control unit 55 displacesvalve 50 to the closed position. - Then, control
unit 55 arrangesshutter 15 in the respective open position. - With reference to
figures 5 to 8 , numeral 10' indicates, as a whole, a filling device according to a different embodiment of the present invention. Filling device 10' is similar to fillingdevice 10 and will be described hereinafter only as far as it differs therefrom; corresponding or equivalent parts of fillingdevices 10 and 10' will be indicated where possible by the same reference numbers. - In particular, filling device 10' differs from filling
device 10 by comprising: - a chamber 60' fluidically connectable with an exhaust 46' or with a
heat source 39 andtank 6; - a fluidic line 61' extending between a segment 43' of
fluidic line 22 interposed betweenmouth 23 andvalve 26 and chamber 60', and along which a valve 62' is interposed; and - a fluidic line 41' extending between chamber 60' and
opening 45 offluidic line 12, and along which a valve 50' is interposed. - The operation of filling device 10' is similar to the operation of filling
device 10 and differs therefrom, in that, during the filling cycle ofarticle 2 with a room temperature carbonated product,valve 26 is maintained bycontrol unit 55 in the closed position and valve 62' is arranged by control unit 55' in the respective open position (Figure 6 ). - Chamber 60' is also connected fluidically by control unit 55' with exhaust 46'.
- Thereby, during the step of filling
article 2 with the pourable product, the gas flowing out fromarticle 2 flows exclusively along fluidic line 61' towards chamber 60' and exhaust 46'. - Accordingly, the gas flowing out from
article 2 does not return totank 6 and is not mixed with the pourable product present intank 6. - According to an alternative configuration of control unit 55 (not shown), during the filling cycle of
article 2 with a room temperature carbonated product,valve 26 is maintained bycontrol unit 55 in the open position and valve 62' is arranged by control unit 55' in the respective closed position. - Thereby, during the step of filling
article 2 with the pourable product, the gas flowing out fromarticle 2 flows exclusively alongfluidic line 22 towardschamber 25 andtank 6. - Differently, with reference to the filling of
article 2 with a room temperature pourable product and in a step of interrupting the operation of filling machine 1,control unit 55 maintainsvalves Control unit 55 fluidically also connects chamber 60' with heat source 39 (Figure 8 ). - Thereby, in case of interruption of the filling step, the pourable product is recirculated between
opening 45, fluidic line 41', chamber 60',heat source 39 andtanks 6 and 7. - From an analysis of the features of
device 10, 10' and according to the present invention, the advantages it allows to obtain are apparent. - In particular, filling
devices 10, 10' allow with a simplified structure to fillarticles 2 both with a pourable non carbonated product at a temperature higher than room temperature and with a carbonated product at a room temperature. - In particular,
fluidic line 22 is formed by asingle duct 30 extending betweenmouth 14 andchamber 25. - Therefore, filing
devices 10, 10' allow to perform the return of gas during the filling step ofarticle 2 or the pressurisation ofarticle 2 before the filling thereof with a gas product, with a particularly simple structure with respect to that shown in the known solutions disclosed in the introductory part of the present description. - Furthermore, filling device 10' is particularly suitable to fill
articles 2 with particularly perishable pourable products. - Indeed, the gas flowing out from
article 2 is conveyed along fluidic line 61' towards chamber 60' and exhaust 46'. Thus, this gas is not mixed with the pourable product present intank 6. - This avoids particularly perishable products from being contaminated when stored in the
tank 6, by the gas flowing out fromarticle 2, during the filling step thereof. - Finally, it is apparent that modifications and variants not departing from the scope of protection of the claims may be made to filling
valve 10, 10'.
