Definitions

  • the present invention relates to a filling valve.
  • the invention relates to a batcher for a filling machine and adapted to dose a pourable product of the type comprising suspended solid particles in a liquid phase, with which a container is filled.
  • such a filling station is fed with aseptic or ultra-clean containers (for example containers which have previously been sterilised) and is adapted to provide containers filled with a sterilised product in aseptic or ultra-clean conditions.
  • aseptic or ultra-clean containers for example containers which have previously been sterilised
  • a filling station usually comprises a carousel conveyor rotating about a rotation axis, a tank containing the product, and a plurality of filling valves which are fluidically connected with the tank and are supported by the carousel conveyor in a radially external position with respect to the rotation axis of the carousel conveyor.
  • Each filling valve substantially comprises a portion for fixing to the carousel defining a filling chamber fluidically connected with the tank, and a filling head arranged along a relative direction parallel to the rotation axis of the carousel.
  • the filling valve must be designed so as to allow, in every moment in time, to maintain the environment, within which the pourable product is handled, free from contamination sources.
  • the batcher must typically be compatible with this kind of operation conditions.
  • the filling head of a flow rate doser generally comprises a shutter mobile, within the relative filling chamber, between a closed configuration, in which the shutter prevents the product from reaching the mouth of the relative container to be filled, and an open configuration, in which the chamber and the container mouth are fluidically connected, thus allowing the product to fill the container.
  • filling valves are known comprising shutters displaying different geometries (for example spherical, butterfly etc.) associated to relative actuating means which can be of different kinds. Whether these filling valves are suitable for specific uses generally depends on the type of product and on the actual operation conditions.
  • pourable products such as fruit juices containing fibres or fruit pieces, or milk based products with the addition of fruit.
  • these products comprise an aqueous liquid phase and contain solid particles having an average size in the range between 0.1 and 10 mm, for example formed by pieces of fruits.
  • the solid particles suspended in the two-phase pourable products can easily obstruct the ducts defined internally by the filling valves provided with shutters having a conventional geometry.
  • liquid phase and the solid phase (particles) were fed along respective separate ducts, for example arranged coaxially one inside the other.
  • each phase substantially flows through a dedicated duct and because, by independently adjusting the flows of the two phases, the frequency of the obstruction can be reduced.
  • the single flow-rates of the two distinct flows must be controlled with precision so as to ensure that the ratio between the two phases, within the filled containers, is at the desired nominal value. Furthermore, guaranteeing the aseptic conditions required by the process results more complex and expensive because it is necessary to maintain them along two hydraulic circuits which are for the most part independent of one another. Accordingly, the sterilising cycles are also substantially doubled.
  • EP0436214A1 discloses a filling valve as defined in the preamble of claim 1.
  • numeral 1 shows as a whole a filling valve adapted to be incorporated in a filling station in aseptic or ultra-clean conditions (not shown) of a filling machine for filling containers with a pourable product.
  • filling valve 1 disclosed herein is suitable for carrying out filling operations which imply a pourable product of the type comprising suspended solid particles in a liquid phase, as for example fruit juices containing fibres and pieces of fruit, or beverages containing milk which contain pieces of fruit or the like.
  • a pourable product of the type comprising suspended solid particles in a liquid phase
  • these are products comprising an aqueous liquid phase, in which average size particles on the order of 0.1 ⁇ 10 mm are suspended.
  • This filling station is typically fed with sterilised empty containers and fills these containers with the pourable product in aseptic conditions.
  • the filling station typically comprises a tank containing the product; a carousel rotating about a vertical axis and protrudingly bearing a plurality of dosers 1 and support elements for respective containers.
  • filling valve 1 comprises:
  • batcher 1 comprises actuating means 50 of shutter body 12.
  • actuating means 50 are completely external to main body 11.
  • main body 11 extends from a first end 13 connectable to the tank to a second end 14 defining a mouth 15 for filling a container. Between two ends 13 and 14, main body 11 comprises a tubular segment 16 having axis A and internal diameter D1 and defining therein a cavity 17 fluidically connected with tank 3.
  • body 11 comprises, downstream of tubular segment 16 with respect to a feeding direction of the product, a portion 18 having a narrowed section, having diameter D2 smaller than diameter D1 of cylindrical segment 16.
  • main body 11 defines therein a seat 19 for shutter body 12 at which, as will be disclosed in greater detail hereinafter, the closed condition between main body 11 and shutter body 12 (see figure 1 ) of the duct, through which the product passes, occurs.
  • actuating means 50 and shutter body 12 are magnetically coupled.
  • shutter body 12 advantageously comprises a pair of permanent magnets 127 and 127', arranged adjacent to one another with identical magnetic poles facing each other axially.
  • actuating means 50 of shutter body 12 advantageously comprise at least one pair of permanent magnets 52 and 52' arranged adjacent to one another with identical magnetic poles facing each other axially, and oriented, with respect to permanent magnets 127, 127' of the pair of magnets of shutter body 12, with different magnetic poles reciprocally facing radially.
  • a pole S (N) of a permanent magnet 127, 127' radially faces a pole N (S) of permanent magnet 52, 52'.
  • magnetic poles reciprocally facing radially there is intended that the poles are, with respect to the axial direction, substantially aligned to one another, although they are materially separate, in the radial direction, at least from the wall of tubular segment 16 of main body 11.
  • permanent magnets 52, 52' result arranged in respective positions radially external with respect to main body 12. More in particular, permanent magnets 52 and 52' are arranged at a radial distance with respect to axis A such as to exert, through the walls of main body 11, a magnetic attraction on shutter body 12 such as to conveniently draw the latter in a translation motion parallel to axis A.
  • Shutter module 12 advantageously comprises (also see Figure 2 ):
  • annular duct 124 adapted to allow the flow of a pourable product comprising suspended solid particles is advantageously defined between stem 121 of shutter body 12 and the internal wall of main body 11.
  • pairs of magnets 127, 127'; 52, 52' can be spaced so as to easily allow the passage of a two-phase liquid containing particles of a given average size without the magnetic coupling between actuating means 50 and shutter body 12 loosing in efficacy.
  • shutter body 12 further comprises a projecting portion 123 having a diameter in the range between diameter D s of stem 121 and internal diameter D1 of tubular segment 16, and adapted to sealingly cooperate with seat 19 in the closed position.
  • Each fin 122 extends radially by a length substantially equal to (D1-D s )/2.
  • diameter D s of stem 121 is in the range between 10 and 50 mm and the ratio (D1-D s )/2 is in the range between 1 and 20 mm.
  • diameter D s of stem 121 is in the range between 15 and 40 mm and the ratio (D1-D s )/2 is in the range between 3 and 15 mm. More preferably, diameter D s of stem 121 is in the range between 20 and 30 mm and the ratio (D1-D s )/2 is in the range between 5 and 10 mm.
  • guide fins 122 are arranged equally spaced angularly about axis A of stem 121.
  • shutter body 12 comprises at least two guide fins 122.
  • guide fins 122 extend in a longitudinal direction parallelly to axis A by an overall length shorter than the overall length of stem 121.
  • shutter body 12 comprises first and second fins 122, 122' arranged according to the same angular distribution about axis A. Thereby, the stability of shutter body 12 within main body 11 results advantageously increased.
  • each fin 122, 122' has a substantially hexagonal right section elongated in an axial direction, so as to display two inclined faces to the flow of two-phase product which passes through duct 124, so that the two-phase product is conveniently deviated so as to flow around fins 122.
  • Other geometries of fins 122 can be similarly advantageous.
  • stem 121 of shutter body 12 comprises (see Figures 1 and 2 ) a tubular portion 125 defining internally a cavity 126 having a substantially cylindrical development, in which the pair of permanent magnets 127 and 127' is housed, arranged adjacent to one another with identical magnet poles facing each other axially.
  • stem 121 further comprises an upstream end portion 121M, for example a conical or frustoconical portion, which may be fixed, preferably in a releasable manner (for example by means of an appropriate threading, not shown in detail), to tubular portion 125 so as to stably contain in cavity 126 the pair of permanent magnets 127 and 127'.
  • upstream end portion 121M for example a conical or frustoconical portion, which may be fixed, preferably in a releasable manner (for example by means of an appropriate threading, not shown in detail), to tubular portion 125 so as to stably contain in cavity 126 the pair of permanent magnets 127 and 127'.
  • stem 121 also comprises a downstream end portion 121V adapted to cooperate, in the closed position of Figure 1 , with filling mouth 15 of main body 11.
  • downstream end portion 121V extends from projection portion 123 facing towards mouth 15 and comprises a substantially frustoconical portion 128 having an increasing diameter from projection portion 123 towards mouth 15 and a substantially conical portion 129 with the vertex facing mouth 15.
  • it is the conical portion 129 that cooperates to close mouth 15 ( Figure 1 ).
  • Shutter body 12 is slidingly housed within cavity 17 of main body 11 and is in particular mobile, within cavity 17, between a relative closed position (see Figure 1 ), in which shutter body 12 cooperates, at least at relative projecting portion 12, with seat 19 defined by main body 11; and a relative maximum open position (see Figure 2 ), in which shutter body 12 leaves the passage in main body 11 at seat 19 free at the maximum.
  • shutter body 12 cooperates with main body 11 also at mouth 15 by means of downstream end portion 121V.
  • actuating means 50 of shutter body 12 comprise:
  • External tubular body 51 is mobile integrally with the actuator and is therefore also mobile between relative upstream (see Figure 2 ) and downstream (see Figure 1 ) stop positions, which correspond to the maximum closed and open positions of aseptic batcher 1.
  • the at least one pair of permanent magnets 52 and 52' arranged adjacent to one another with identical magnetic poles facing each other axially is advantageously housed within external tubular body 51, permanent magnets 52 and 52' being coupled magnetically with shutter body 12 (i.e. with permanent magnets 127 and 127'). More in particular, permanent magnets 52 and 52' of the at least one pair of magnets of external tubular body 52 are arranged with respect to permanent magnets 127, 127' of the pair of magnets internal to stem 121, with different magnetic poles reciprocally facing radially.
  • a pole S (N) of a permanent magnet 127, 127' radially faces a pole N (S) of permanent magnet 52, 52'.
  • this specific reciprocal arrangement determines a considerably increased attraction force between shutter body 12 and external tubular body 51, such that a distance can be interposed between pair of magnets 127, 127' and the at least one pair of magnets 52, 52', the distance being given, as well as by the wall of tubular segment 16, by the radial development of fins 122, without the magnetic coupling between actuating means 50 and shutter body 12 seizing.
  • the permanent magnets can be advantageously formed by sets of smaller magnets stacked so that in each set there is in any case an overall orientation of the polarities equivalent to that of a single larger magnet. It will be understood that this alternative solution can be advantageously extended to any pair of magnets in filling valve 1, comprising that of magnets 127, 127' internal to stem 121 of shutter body 12.
  • the external tubular element 51 defines therein at least one cavity 53 adapted to house a corresponding pair of magnets 52, 52', and comprises a main portion and a covering portion fixable to the main portion, preferably in a releasable manner, so as to stably contain, within the at least one cavity 53, the corresponding at least one pair of permanent magnets 52, 52'.
  • external tubular element 51 defines therein at least one plurality of cavities 53 within which a corresponding plurality of pairs of permanent magnets 52, 52' is housed, arranged preferably equally spaced angularly about axis A.
  • actuation for example pneumatic actuation
  • actuating means - i.e., for example, the resulting translating motion of the above said piston within the relative cavity - conveniently determines a corresponding axially directed translating motion of shutter body 12 within main body 11.
  • filling valve 1 can be conveniently inserted in a filling station advantageously also comprising control means (not shown) adapted to actuate batcher 1 according to the desired filling procedure.
  • filling valve 1 can also be used to implement a filling procedure which provides the steps of fast and slow filling, at which the degree of opening of filling valve 1 (i.e. the position of shutter body 12) can be appropriately adjusted providing a partial opening configuration, corresponding to slow filling, in which shutter body 12 is conveniently brought to an intermediate position between the closed position ( Figure 1 ) and the maximum open position ( Figure 2 ) which corresponds to the rapid filling.
  • filling valve 1 allows to carry out the filing of a container with a two-phase pourable product according to the typical needs of the sector of the filling machines for the food sector, ensuring the desired aseptic conditions and very short response times to switch between different degrees of opening/closing of the batcher.
  • filling valve 1 allows to easily fill containers with a two-phase pourable product, providing for this purpose a duct having a size appropriately compatible with that of the particles contained in the pourable product that flows along the duct.
  • the filling valve according to the invention allows to considerably reduce the occurrence of obstructions, even partial ones, thus limiting accordingly the need for maintenance intervention and, as a consequence, down times.
