Definitions

  • the present invention relates to a filling device volumetric of flasks, bottles or other similar containers, to be filled with a liquid product, whether or not containing gas.
  • the bottle to be filled comes into contact with a filling valve, the seal between the bottle and the valve being ensured by a seal.
  • a filling valve For certain products, it is necessary to create a vacuum before filling; but, he is impossible, in the case of plastic bottles of a certain flexibility, to create a vacuum during this phase without deformation of the bottle.
  • the bottle When filling bottles with a gaseous product, the bottle may burst or break under pressure.
  • level In known filling installations known as "level", the degree of filling is defined only by the level of product reached in the vial. The actual amount of product introduced into each bottle therefore varies, depending on the deformation of the bottle or according to dimensional tolerances of glassware. It cannot therefore be guaranteed that the each bottle is filled with a quantity of product constant and precise.
  • the opening of the filling is carried out by a mechanical valve controlled from the outside by a controlled key or a cam, which involves numerous seals and other mechanical components, such as springs, which make the disinfection of the difficult and imperfect filling valve.
  • the present invention aims to overcome the aforementioned drawbacks current filling facilities, by providing a device for volumetric filling which mainly allows filling under pressure or with a vacuum phase, this device also ensuring filling each container with a constant and precise dose, and can be easily cleaned.
  • the invention essentially relates to a device volumetric filling of flasks, bottles and other containers, comprising a metering device, a filling spout connected to the device dispenser, and a support device located under the filling spout and receiving a container to be filled, characterized in that the device for support is completed by a vertically movable sheath or "bell", under the action of control means, and able to come into tight contact, by its free upper or lower part, with a complementary part belonging to the filling spout or the support device, so to delimit a closed enclosure trapping the container to be filled placed on the support device.
  • a vertically movable sheath or "bell” under the action of control means
  • the sheath has a free upper edge, cooperating with a peripheral flange formed at the base of the filling spout, especially around a filling, an annular seal being inserted under the flange.
  • the sleeve is slidably mounted in the direction vertical in a cylindrical jacket of the support device, the part lower of the sleeve being provided with a piston and the support device being thus shaped as a jack, to control the vertical movement of the scabbard.
  • Other control means notably mechanical, such as cam and / or spring, are also possible to move vertically said sheath.
  • This sheath or bell which in particular in the high position comes in tight contact with the periphery of the filling valve, delimits an enclosure or chamber in which the container to be filled is trapped and can thus be filled, under gas pressure or not, without contact with the filling spout.
  • This device can also be used for sterilizing the container to be filled, as well as the filling member, providing that associated, to the support device with sheath and / or to the spout filling, means for injecting steam or other sterilizing gas in the enclosure delimited by the sheath held in particular in position high.
  • the device doser comprises on the one hand a buffer tank, intended to be filled in liquid to be dosed up to an intermediate level, the interior volume located above of this level being filled with air or gas, and on the other hand a metering device cylindrical, open at its upper part and communicating through its part lower with a flow channel formed inside the spout filling, the cylindrical metering device being housed at least partially in the buffer tank, and mounted sliding in a vertical direction, means for control being provided for moving said metering device between a position low, in which its open upper part is immersed in the liquid contained in the buffer tank, and a high position in which its upper part enters the volume of air or gas present above of the liquid level, so as to isolate a dose of liquid.
  • the upper edge of the dispenser ensures the separation of the liquid contained in the dispenser (and reaching said upper edge), relative to the rest of the liquid contained in the tank.
  • the amount of liquid thus isolated in the doser can then flow by gravity, through the filling spout (the valve is then open), up to the container to be filled.
  • the bottom of the cylindrical dispenser consists by an internal piston whose position is vertically adjustable, so as to allow selection or adjustment of the volume of liquid can be isolated, at each operating cycle, by said metering device.
  • the cylindrical metering device is guided in vertical translation through a circular opening formed in the lower wall of the buffer tank.
  • the control means vertically moving the metering device, may be in the form of a self-contained actuator, such as a cylinder.
  • a self-contained actuator such as a cylinder.
  • the spout filling is fixed by its upper part to the lower part of the cylindrical dispenser, and the vertical displacement of this cylindrical dispenser is controlled from the vertical displacement of the sheath associated with support device, this via the filling spout.
  • the filling spout carries, at its lower end, a filling valve including a shutter valve made by a membrane in particular in the shape of a body hollow, of elastically deformable material, means being provided for the admission of compressed air or other gas under swelling pressure said shutter valve so as to apply it against an internal wall of the filling valve and thereby seal the outlet of the channel liquid flow.
  • a filling valve including a shutter valve made by a membrane in particular in the shape of a body hollow, of elastically deformable material, means being provided for the admission of compressed air or other gas under swelling pressure said shutter valve so as to apply it against an internal wall of the filling valve and thereby seal the outlet of the channel liquid flow.
  • a controlled valve connected to an external source compressed air or other pressurized gas, the same valve ensuring the admission of air or gas to the upper volume of the buffer tank, as well as, by at least one vertical tube passing through the filling spout, towards the inflatable shutter valve.
  • this inflatable valve closing the flow channel, automatically deflates when the equilibrium is reached between the buffer tank and the inside of the sleeve.
  • the same controlled valve can also be used to set up communication with the open air the enclosure delimited by the sheath, this by through channels passing through the spout and the filling valve.
  • the volumetric filling device shown in its together in FIG. 1, comprises three main parts from top to bottom, namely a metering device 1, a filling spout 2 with valve shutter, and a support device with bell 3, the latter receiving a bottle 4 (or other container) to be filled with a liquid.
  • the metering device 1 comprises a shaped buffer tank 5 cylindrical, and of vertical axis 6, delimited by a horizontal wall upper 7, a lower horizontal wall 8 and a side wall 9.
  • the buffer tank 5 has at its top a valve 10 controlled by a rotary cam 11 and connected to a compressed air supply.
  • This buffer tank 5 also includes, at its upper part, orifices 12 for the supply of the product to be dosed. In use, the buffer tank 5 thus contains a certain amount of liquid 13 to be dosed, and above the level 14 of this liquid, an air volume 15.
  • the bottom wall 8 of the buffer tank 5 is pierced with a wide circular opening, in which is slidably mounted, along the axis vertical 6, a generally cylindrical dispenser 16, open at its part superior.
  • the lower part of the metering device 16 is shaped externally in annular piston 17, slidably mounted in a cylindrical jacket 18 fixed coaxially under the bottom wall 8 of the buffer tank 5 - see also figure 6.
  • the filling spout 2 comprises a vertical tube 19, mounted along the aforementioned vertical axis 6 and fixed, by its upper end, under the metering device 16. At its lower end, the tube 19 carries a valve filling 20, the active element of which is a shutter valve 21, produced like an inflatable membrane, made of elastically deformable material, forming a kind of hollow body. In the inflated state, the shutter valve 21 cooperates with the internal wall of the filling valve 20, to close the outlet of the liquid flow channel 22 delimited by the tube 19.
  • FIG. 7 shows, in more detail, the shutter valve 21 in the state inflated
  • FIG. 8 shows the same shutter valve 21 in the state deflated, allowing the liquid to flow through the valve filling 20.
  • the shutter valve 21 is connected to the upper valve 10 by two coaxial tubes 23 and 24, with telescopic structure, arranged according to vertical axis 6.
  • the support 3 is located under the filling valve 20, along the vertical axis 6. It has a base 25, a vertical rod 26 fixed to the center of the base 25, and an upper circular plate 27, mounted at the top of the rod 26 and serving as a support surface for the bottle 4 to be completed.
  • the base 25 still supports a cylindrical jacket outer 28, coaxial with the central rod 26.
  • a cylindrical sleeve 29, also called “bell” is slidably mounted, guided vertically by the shirt 28 and passing around the plate higher 27.
  • the lower part of the sleeve 29 is integral with a piston annular 30, slidably mounted around the central rod 26.
  • the support with bell 3 is cylindrical, with two chambers 31 and 32 delimited respectively above and below the piston 30, and with control fluid arrivals / departures 33 and 34 for the supply and the purge of the two chambers 31 and 32, the supply of the upper chamber 31 carried out via a channel 35 formed in the central rod 26.
  • the filling valve 20 has a flange peripheral 36, located opposite the free upper edge 37 of the sleeve 29, an annular seal 38 being inserted under the flange 36.
  • these arrangements allow interaction of the sheath 29, the beak of filling 2 and doser 1-16, thus avoiding, in particular, the installation an additional cylinder to control the raising and lowering of the dispenser cylindrical 16.
  • the valve 20 of the nozzle 2 is closed by the pressure of the admitted air in the shutter valve 21, and the metering device 16 occupies a low position and is immersed in the liquid 13 contained in the buffer tank 5, partially filled, the liquid level 14 being controlled and maintained in permanence, in a known manner.
  • the bottle 4 to be filled is deposited, by a gripping device (not shown), on the upper plate 27 of the support 3, the sheath 29 of which initially occupies a low position, retracted into the folder 28.
  • the metering device 16 When rising, the metering device 16 manages to protrude above the level 14 of the liquid 13, in the air volume 15.
  • the liquid 39, contained in the metering device 16, is then isolated from the remainder of the liquid 13 of the buffer tank 5.
  • the upper valve 10 is then actuated, to send part of the air 15 from the tank to the sheath 29, through the tube 23 that extends a channel formed in the body of the valve 20.
  • This valve 10 at the same time evacuates (via the tube 24) the compressed air contained in the shutter valve 21, so that the latter returns to its original shape and frees the passage of the liquid through the filling valve 20.
  • the liquid 39, isolated in the metering device 16, can then flow through the channel 22, escape from the spout 2 through the open filling valve 20, and pour into the bottle 4, the opening of which is located under the outlet orifice of said valve 20 - see Figure 3.
  • the sheath 29 is kept lifted and applied against valve 20, with interposition of the seal 38, and it traps the bottle 4 tightly between the plate 27 and said valve 20.
  • the sealed enclosure 40 thus delimited, it is possible to execute operations such as vacuum or pressure, sterilization, etc ... (see also below).
  • valve 10 When the metering device 16 has emptied its entire volume of liquid 39 into the bottle 4, the valve 10 is again actuated to send air compressed in the shutter valve 21, which inflates and closes thus the filling valve 20 - see figure 4. Using the same valve 10, the enclosure 40 delimited by the sheath 29 is also placed communication with the open air, so that it regains pressure atmospheric.
  • the upper chamber 31 of the jack formed by the support 3 is then supplied, to allow the sheath 29 to descend into the interior of shirt 28 - see figure 5.
  • the upper edge 37 of the sleeve 29 separates from the valve filling 20 integral with the metering device 16, this occurring when the piston 17 comes into abutment at the base of the shirt 18.
  • the dispenser 16 thus resumes its position immersed in the liquid 13 of the buffer tank 5, and it fills again of this liquid.
  • each bottle 4 receives a constant quantity of liquid and precise, determined by the characteristics of the metering device 16. Nevertheless, this quantity is adjustable, providing that the bottom of the useful volume of the dispenser consists of an annular piston 41, of adjustable position vertically, from the outside, relative to the cylindrical body of said metering device 16. As shown in FIG. 6, the annular piston 41 is integral from the upper end of the tube 19 of the filling spout 2, this tube 19 being linked, via an internally threaded ring 42, to a externally threaded flange secured to the doser base 16. Rotation of the ring 42 thus makes it possible to control the raising or lowering of the piston 41 relative to the metering device 16.
  • the ring 42 can be positioned at different levels, relative to the tube 19, thanks to multiple annular grooves 43 formed on the tube 19.
  • the rise of the piston 41, for the passage from one adjustment position to another, can be controlled by compressed air, injected through an orifice 44, in the manner a jack. This allows fine and coarse adjustment.
  • Figure 9 illustrates a variant of the filling device previously described, specially equipped for carrying out a phase sterilization of the bottle 4 to be filled, when it is isolated in the sealed enclosure 40 delimited by the sheath 29 in the high position.
  • a 45 superheated steam inlet is provided on the filling valve 20, and allows this vapor to be injected into the enclosure 40.
  • a tube 46 starting from the plate 27 and directed downwards, through the piston 30 and the base 25 of the support 3, ensures the outlet of the condensed steam.
  • FIG. 10 shows the detail of the controlled valve 10, usable in the case of the two embodiments previously described.
  • the body 47 of the valve 10 has internal channels 48 and 49, which are related to the arrival of compressed air, with the interior of the buffer tank 5, and with the upper parts of the vertical tubes 23 and 24.
  • the rotating part 50 of the valve 10, linked to the control cam 11, includes other channels such as those 51 and 52, which depending on the position angular of this rotating part 50 allow various combinations, necessary for the execution of the operating cycle previously described.
