Abstract
Description
- The present invention relates to a contactless filling device for filling an article with a pourable product having a temperature higher than room temperature.
- The present invention also relates to a control method of a contactless filling device for filling an article with a pourable product having a temperature higher than room temperature.
- More in particular, the present invention relates to a filling device 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.
- 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 a plurality of filling devices supported by the carousel conveyor in a position radially external with respect to the rotation axis of the carousel conveyor.
- In greater detail, the carousel is provided with a plurality of support elements for respective articles provided to arrange the mouths of respective articles in a lower position and at a given distance 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.
- Each filling device essentially comprises a fixed body connected to the carousel and a shutter sliding with respect to the fixed body between an open position and a closed position.
- In greater detail, when the shutter is arranged in the open position, the shutter defines an opening with the fixed body. The pourable product thereby flows from the tank to a filling mouth of the relative article passing through the opening.
- Differently, when the shutter is arranged in the closed position, it sealingly cooperates with an abutment surface defined by the fixed body, preventing the pourable product from flowing from tank towards the mouth of the relative article.
- In case of contactless filling of still products, the opening is arranged at a given distance from the mouth of the article to be filled.
- For example,
WO2008/141717 discloses filling devices capable of contactless filling articles with a hot pourable product. - In order to perform the filling with a hot pourable product, the components of the filling device can be maintained hot when the filling of the articles is interrupted.
- The filling devices shown in the above said patent application also allow the circulation of a sanitising fluid within the components thereof, so as to periodically sterilise the components in contact with the pourable product.
- To perform the above said operations, the filling devices of the known type comprise a first fluidic line along which the shutter slides between an open and a closed position. When the shutter is arranged in the closed position, it sealingly separates the first fluidic line in a first portion fluidically connected to the tank and a second portion connected to a filling mouth for the articles.
- The first fluidic line also comprise a bell element defining a filling opening of the filling device.
- The filling device also comprises:
- a common manifold, in turn connected with a heating boiler and with a tank;
- a first seat fluidically connected with the first portion of the first fluidic line and a first duct connected to the manifold; and
- a first pressure limiting valve housed within the seat and displaceable between respective open and closed positions to control the flow from the first fluidic line to the first duct.
- More in particular, the first limiting valve automatically allows the flow from the first fluidic line to the first duct, only when a first value of the pressure difference at its sides is overcome.
- When the shutter is arranged in the closed position, the pressure in the first portion of the first fluidic line increases until the first valve is displaced in the respective open position.
- Thereby, the pourable product continuously circulates from the tank to the manifold and, from the latter to the boiler, remaining hot.
- When the shutter is displaced to the respective open position to perform the filling, the pressure in the first portion decreases. Accordingly, the first valve returns to the respective closed position and prevents the circulation of the pourable product along the manifold.
- In other words, when the shutter reaches the closed position, it automatically controls the opening of the first valve.
- The filling device finally comprises:
- a second seat;
- a second duct interposed between the first duct and the bell element; and
- a second pressure limiting valve housed within the seat and displaceable between respective open and closed positions to control the flow between the first and the second duct.
- More precisely, the second pressure limiting valve automatically allows the flow from the first fluidic line to the first duct, when a second value, greater than the first value, of the pressure difference at its sides is exceeded.
- When the filling device needs to be sterilised, a closing element is placed to close the pouring opening and the tank is filled with a sanitising fluid at a pressure higher than the pressure of the pourable product. In particular, the pressure of the sanitising fluid is such as to displace both the first and the second pressure limiting valves to the respective open positions.
- The shutter is also arranged in the respective open position so as to automatically displace the first valve to the respective open position.
- The sanitising fluid can therefore flow within the first fluidic line of the first duct towards the common manifold and at the same time induce the opening of the second valve.
- The sanitising fluid in the first duct also induces the displacement of the second valve to the open position and can therefore sterilise the bell element and reach the common manifold.
- The Applicant has observed that the fact that the first and the second valves are pressure limiting valves sets some limits to the operation flexibility of the filling device.
- For example, the first valve automatically reaches the relative closed position, when the shutter reaches the relative open position.
- The need is felt in the sector to provide filling devices which can fill articles with a hot pourable product and which can be sterilised with a sanitising fluid, which allow for operation modes as flexible as possible.
- In particular, the carousel carrying the filling devices covers a circular path comprising:
- an operative segment disclosed from a station for withdrawing articles to be filled towards a station for releasing the articles filled with the pourable product; and
- a return segment disclosed from the release station towards the withdrawal station.
- The need is felt, along the return segment and during a step of filling the articles, both to prevent the recirculation of the hot pourable product and to maintain the shutter in the respective closed position.
-

device 10 finally comprises a fillingvalve 15 housed withinduct 12. -
Valve 15 can be displaced between: - an open position in which it allows the flow between
mouth 13 and pouringopening 14; and - a closed position in which it sealingly separates
mouth 13 and pouringopening 14. -
Valve 15 also comprises a shutter 17 that moves forwards and backwards along axis B between a closed position and an open position, and ends, on the side of pouringopening 14, with anaxial end projection 18. - More precisely,
projection 18 is arranged with respect tosection 16 on the side of pouringopening 14. - When shutter 17 is arranged in the closed position,
projection 18 abuts againstframe 11, atsection 16. Thereby,mouth 13 and pouringopening 14 are sealingly separated. - When shutter 17 is arranged in the open position (shown in
figure 1 ),projection 18 is spaced fromsection 16 and exposes anopening 19, which fluidically connectsmouth 13 and pouringopening 14. -
Frame 11 further comprises: - a
duct 20 extending betweenmouth 21 ofduct 12 and amouth 22; - a
duct 25 extending between pouringopening 14 and amouth 26; - a
duct 30 fluidically connected withmouths
and - a
chamber 31 fluidically connected withduct 30. -
Mouth 21 is open induct 12 in a position axially interposed betweenmouth 13 andsection 16. More in particular,mouth 21 is open induct 12 immediately abovesection 16. Thereby, both when shutter 17 is arranged in the closed position and when shutter 17 is arranged in the open position,duct 20 is fluidically connected withtank 6. - Filling
device 10 also comprises: - a
valve 41 housed withinduct 20; and - a
valve 42 housed withinduct 25. -
Valve 41 is adapted to allow recirculation of the pourable food product during a step of interrupting the filling ofarticles 2. - More in particular, the pourable food product recirculates between
duct 20,duct 30,chamber 31,heat exchanger 39 andtank 6 and therefore is maintained at the filling temperature. Thereby, when the filling ofarticles 2 starts again, the pourable product is already at the filling temperature higher than room temperature. - Advantageously,
valve 41 may be displaced between the respective open and closed positions, independently of the pressure difference existing betweenmouths duct 20. - In other words, the displacement of
valve 41 between respective closed and open positions is controlled by means of a control external toduct 20 and according to an operation law set during the step of setting the filling machine. -
Valve 41 is housed within aseat 43 defined byframe 11. -
Seat 43 is defined by a pair ofwalls annular wall 57 axially interposed betweenwalls -
Valve 41 essentially comprises: - a
sleeve 50 fixed to wall 57 ofseat 43; - a
piston 51 mobile withinseat 43 parallelly to axis B, having afrustoconical end 54 and connected tosleeve 50 by means of compressible bellows; and - a
spring 52 interposed betweensleeve 50 andpiston 51 and preloadingvalve 41 towards the open position. -
Wall 56 definesmouth 22. -
Wall 55 andpiston 51 also define achamber 58 within which a pressurised fluid is present, in particular air. This fluid can be discharged fromchamber 58 in a manner which is not shown. - The pressure in
chamber 58 arrangesend 54 sealingly in abutment within mouth 22 (figure 1 ). - Differently, when the fluid is discharged from
chamber 58,spring 52 extends and end 54 defines withwall 56 an opening, which is fluidically connected withmouth 22. In other words,valve 41 is arranged in the open position, discharging the fluid fromchamber 58. -
Valve 42 is adapted to control the flow of a sanitising fluid, during a step of sterilising fillingdevice 10. - As shown in
Figure 2 , aclosing element 45 is connected to frame 11 to close pouringopening 14 during the step of sterilising, so as to preventing the sanitising fluid from exiting from pouringopening 14. - Closing
element 45 also fluidically connectsducts - Closing
element 45 finally lies on a plane orthogonal to axis B, when it is arranged so as to close pouringopening 14. -
Valve 42 may be displaced automatically between a closed position in which it fluidically isolates pouringopening 14 andmouth 26, and an open position in which it fluidically connects pouringopening 14 andmouth 26. -
Valve 42 is, in the case shown, a pressure limiting valve, i.e. it is automatically displaced in the open position when a given pressure difference between pouringopening 14 andmouth 26 is reached. -
Valve 42 is also a check valve, which allows the flow fromduct 12 toduct 30 throughduct 25, when closingelement 45 is fixed to frame 11. - Differently,
valve 42 shuts off the flow fromduct 30 toduct 12. - More in particular,
valve 42 comprises: - a
stem 47 sliding withinduct 25 and provided with ashutter 48; and - a
spring 49 loading stem 47 towards the closed position. -
Shutter 48 defines an opening with the portion offrame 11, whenvalve 42 is arranged in the open position and shuts this opening, whenvalve 42 is arranged in the closed position shown inFigure 1 . -
Chamber 31 is connected by means of arotating manifold 38 with fixedheat exchanger 39. - The operation of filling
machine 1 is disclosed hereinafter, with reference to only onefilling device 10 and a singlecorresponding article 2. - More precisely, the operation of filling
machine 1 is disclosed hereinafter during a "hot" filling step ofarticle 2 with a still pourable food product. - In particular,
tank 6 is filled with the hot pourable food product at a first pressure value. -
Carousel 3 receivesarticle 2 to be filled fromconveyor 4 at station I of path P, and feeds filledarticle 2 toconveyor 5 at station 0 of path P. - More precisely,
article 2 is arranged so thatmouth 8 is below pouringopening 14 ofduct 12. - It is important to stress that, during the whole filling of
article 2,mouth 8 remains at a certain distance from opening 14 along axis B. In this way, fillingdevice 1 carries out a contactless filling ofarticle 2. -
Valve 15 is arranged in the relative open position during segment R of path P, so as to perform the filling ofarticle 2 with the hot pourable food product. -
Valves 41, 42 (figure 4 ) are arranged in the relative closed positions, along segment R of path P. Thereby, the pourable food product cannot flow alongducts -
Valve 15 is displaced to the relative closed position along segment S of path P. -
Valves - When the above said step of filling needs to be interrupted without stopping filling
machine 1, for example because the feeding ofarticles 2 has been interrupted, a step of recirculating the pourable food product is performed therein alongduct 12,duct 20,duct 30,chamber 31,exchanger 39 andtank 6. - Thereby, the pourable food product is continuously heated by
exchanger 39 and can be immediately used to fillarticle 4 when the filling steps is resumed. - The step of recirculating is performed by arranging
valve 41 in the relative open position along whole path P, so as to fluidically connectducts valves - When it is necessary to perform a sterilisation of the parts of filling
machine 1 in contact with the pourable food product,tank 6 is filled with a sanitising fluid and a closing element 45 (figure 2 ) is arranged so as to close pouringopening 14, so as to prevent the sanitising fluid from flowing out of the pouringopening 14. - More in particular, closing
element 45 fluidically connectsducts - During the sterilising step,
valves - Thereby, the sanitising fluid can flow from
tank 6 along thewhole duct 12 and pass throughwhole duct 20 up toduct 30. - The sanitising fluid also flows from
duct 12 toduct 25 and, in virtue of its pressure, automatically arrangesvalve 41 in the open position along whole path P. - The sanitising fluid thereby flows along
whole duct 25 until it reachesduct 30 and from here tochamber 31 and then return totank 6. - With reference to
figure 5 , 10' indicates, as a whole, a filling device according to a different embodiment of the present invention. The 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 valve 42' controllable independently of the pressure difference between pouringopening 14 andmouth 26, once closingelement 45 has been connected to frame 11 so as to close pouringopening 14. - In other words, the displacement of valve 42' between the respective closed and open positions is controlled by means of a control external to
duct 25 and according to an operation law set during the step of setting the filling machine. - Valve 42' is arranged within a seat 60' arranged externally to
duct 25 and controls the flow between a first portion 61' ofduct 25 originating in pouringopening 14 and a second portion 62' ofduct 25 ending inmouth 26. - Valve 42' essentially comprises:
- a support body 63' fixed within seat 60';
- an elongated stem 64' mobile orthogonally to axis B;
with respect to support body 63'; and - a membrane 65' having opposite ends 70' fixed to frame 11, and a central portion 71' fixed to stem 64'.
- Valve 42' essentially comprises:
- a spring 66' interposed, on the opposite side of membrane 65', between stem 64' and
frame 11; - an open duct 67' within seat 60' on the side of spring 66' with respect to stem 64' and fluidically connectable selectively to a source of pressurised fluid, in particular pressurised air; and
- an open duct 68' within seat 60' on the side of membrane 65' with respect to stem 64' and fluidically connectable selectively to a source of pressurised fluid.
- Valve 42' is maintained in the relative closed position by the action of the preload of spring 66' and by the action of the pressure of the fluid fed from duct 67' within seat 60' on the side of spring 66' with respect to stem 64'. These actions load stem 64' towards membrane 65' and maintain central portion 72' of membrane 65' in the flat configuration.
- Valve 42' is displaced in the relative closed position connecting duct 68' to the pressure source and discharging duct 67'. Thereby, a pressure is generated on membrane 65' directed towards stem 64'. This action arranges central portion 71' of membrane 65' in the curved configuration, compresses spring 66' and fluidically connects portions 61', 62' of
duct 25 to one another. - In particular, ducts 67', 68' are connected to the pressure source by means of respective ducts (not shown) external to frame 11.
- The operation of filling device 10' differs from the operation of filling
device 10 in that the opening and the closing of valve 42' are controllable independently of the pressure difference between pouringopening 14 andmouth 26. - In other words, the displacement of valve 42' between respective closed and open positions is controlled by means of a control external to
duct 25 and according to an operation law set during the step of setting the filling machine. - With reference to
figure 6 , 10" indicates, as a whole, a filling device according to a different embodiment of the present invention. Fillingdevice 10" is similar to filling device 10' and will be described hereinafter only as far as it differs therefrom; corresponding or equivalent parts of fillingdevices -
Valve 42" ofdevice 10 " differs from valve 42' of device 10' by being similar tovalve 41. - In detail,
valve 42" is housed within aseat 43" defined byframe 11. -
Seat 43" is defined bywalls further wall 57" offrame 11" interposed axially betweenwalls Wall 57" is also adjacent to and integral withwall 57. -
Duct 25" differs fromduct 25 by comprising amouth 26" passing throughwall 56 and amouth 80" passing throughwall 57. - In particular,
mouth 26" is fluidically connected toduct 30 andmouth 80" is fluidically connected to pouringopening 14, once closing element 45 (not shown infigure 6 ) has been applied toframe 11. -
Mouths 80", 26" are respectively arranged upstream and downstream ofvalve 42", according to a feeding direction of sanitising fluid from pouringopening 14 toduct 30. -
Valve 42" essentially comprises: - a
sleeve 50" fixed to wall 57" ofseat 43; - a
piston 51" mobile withinseat 43" parallelly to axis B, having afrustoconical end 54", and connected tosleeve 50" by means of compressible bellows; and - a
spring 52" interposed betweensleeve 50" andpiston 51" and preloadingvalve 42" towards the open position. -
Wall 55" andpiston 51" also define achamber 58" within which a pressurised fluid is present, in particular air. This fluid can be discharged fromchamber 58" in a manner which is not shown. - The pressure in
chamber 58" arrangesend 54" sealingly in abutment withinmouth 22" (figure 6 ). - Differently, when the fluid is discharged from
chamber 58",spring 52" extends and end 54 defines an opening withwall 56", which opening is fluidically connected withmouth 22". In other words,valve 42" is arranged in the open position, discharging the fluid fromchamber 58". - It should be noted that
chamber 58" is fluidically connected withdistributor 81 in a manner which is not shown and by means of ducts obtained withinframe 11. - The operation of
device 10" differs from the operation of device 10' in thatpiston 51" ofvalve 42" is elastically preloaded byspring 52" towards the open position and is displaceable to the closed position by feeding a pressurised fluid withinchamber 58". - From an analysis of the features of
devices - In particular,
valve 41 is controllable independently of the pressure difference induct 25 betweenmouths - Thereby, the operation modes of filling
device - For example, both
valves - There follows that, when filling
device machine 1, bothvalves articles 2. - The flexibility of filling
device 10', 10" is further increased by the fact that alsovalve 42', 42" is controllable independently of the pressure difference withinduct 25 between an upstream section and a downstream section of the above saidvalve - In virtue of this, valve 42' can always be maintained during the step of filling
articles 2. - Thereby, in case the pressure is increased in
duct 30, the pourable product is prevented from returning alongduct 25 and reaches pouringopening 14. Accordingly, dripping of the pourable food product from pouringopening 14 is avoided, during the step of recirculating the pourable product. -
Device 10" comprisesvalves distributor 81 by means of ducts obtained internally to frame 11. - Accordingly,
device 10" requires no further ducts external to frame 11 to control the displacement ofvalves - Finally, it is apparent that modifications and variants not departing from the scope of protection of the claims may be made to filling
device - In particular, the bellows of
valves
