Definitions

  • This invention relates to a gravity filling valve device with a self-levelling system operating under slight gas pressure, for bottling machines.
  • valve After filling, to ensure that all the bottles are filled with the same quantity of liquid the valve effects an operation known as "levelling". This consists in practice of removing from the bottle that (variable) liquid quantity in excess of a predetermined level equal for all the bottles, and set in proximity to the bottle mouth.
  • the levelling operation is such that the removed and/or transferred liquid come into contact with the atmosphere, with consequent contamination.
  • the object of the invention is to obviate the aforesaid drawbacks by providing a gravity filling valve device able to execute all the bottling stages without the liquid coming into contact with the atmosphere.
  • inert gas is pumped into the bottle through the lower part of the vertical duct, to remove the excess liquid quantity from the bottle through the coaxial tube.
  • This liquid quantity reaches the tank, from which it is transferred by gravity without contact with the atmosphere.
  • the bottled liquid quantity also does not come into contact with the atmosphere.
  • the gravity filling valve device 1 is positioned below a tank 2 of a bottling machine 3 (only partly visible) for ungassed liquids 4 which are to be transferred into bottles 5.
  • tubular or sleeve elements comprising, in the stated order from the outside to the inside of the valve device 1, a first element 7, a second element 8, a third element 9, a fourth element 10, and a tube 11.
  • the element 7 enables the valve 1 to be fixed to the machine structure 3, and in particular to the tank 2, against which it is hydraulically sealed by the ring gasket 12.
  • the element 8 can slide axially within 7 under fluid-tight conditions by virtue of the ring gasket 13.
  • the ring gasket 13 In it there are provided two slots 14 which connect the tank 2 to a vertical duct 15 of annular cross-section defined between the elements 10, 8 and 9.
  • an elastic element preferably a helical spring 16, which is in a compressed state when the valve 1 is at rest (see Figure 1).
  • the elements 8 and 10 can slide relative to each other or float along the axis 6 through a certain part of their length, ie until the shoulder 17 on the element 8 engages the lower shoulder 18 to open the duct 15, or the upper end 19 of the element 8 engages the upper shoulder 20 on the element 10 to close the duct 15.
  • a cavity 21 housing a second elastic element, preferably a helical spring 22, which is compressed against the element 9 when the valve 1 is at rest.
  • a cam 23 acts on this lower end of the element 8 via a preferably idle roller 24.
  • the idle roller 24 rotates on a pivot 28 having its axis 25 perpendicular to the axis 6 and fixed on a collar 29.
  • the collar 29 is fixed to the lower end of the tubular element 8 by at least two pins 30.
  • a third elastic element preferably a helical spring 26, which is compressed and hence preloaded when the valve 1 is at rest.
  • the tubular element 9 supports a reference pin 31, the position of which relative to a recess 32 in the tubular element 8 determines the angular phasing of the hose 37 to the axis 25.
  • a syphon trap 33 Between the lower ends of the tubular elements 9 and 10 within the vertical duct 15 there are provided, in the stated order from the top downwards, a syphon trap 33, a conical sealing surface 34 coaxial with the bottling axis 6, a ring gasket 35, a communication hole 36, a hose 37, and a ring seal gasket 38.
  • the hose 37 connects the hole 36 to a valve 39 fixed to an annular vessel 39/1 which delivers an inert gas 40/1 having characteristics identical to the gas in the tank 2 above the liquid 4 to be bottled, but at a slightly higher pressure.
  • the valve 39 is normally closed, but opens by the action of a stem 41 operated by the cam 41/1 positioned on members, not shown, of the bottling machine 3.
  • the annular gasket 38 seals hydraulically against the neck 42 of the bottle 5.
  • the lower end of this latter is in two pieces, of which the lower element 43 is annular.
  • the final part of the element 10 is conical and is directed towards the inner surface of the neck 42 of the bottle 5.
  • the tube 11 is slidable within the element 10 connected to the rod 45, which is operated by the cams 44 and 44/1.
  • the tube 11 is provided with a hole 46 through which the excess liquid passes on its return, mixed with the inert gas 40/1 fed during the levelling stage.
  • the bottle 5 to be filled is in position below the filling valve 1.
  • the bottle can be positioned either by being moved relative to the base of the bottling machine 3, or by the filling valve 1 being moved relative to the base of the machine 3, or by both the bottle 5 and the valve 1 being moved relative to the base of the machine. In this case however, the filling valve is moved relative to the base.
  • the cam 23 ( Figure 9) acts via the roller 24 on the tubular element or sleeve 8 so as to maintain it urged upwards and preload the helical spring 26.
  • the tube 11 is in its retracted position and the inert gas 40 which has penetrated into the tube 11 through the holes 46 leaves from the central bore downwards ( Figure 7).
  • the vertical duct 15 is closed by the engagement between the annular gasket 35 and the conical sealing surface 34 (see Figure 8).
  • the valve 39 is closed.
  • the bottle entry stage is followed by the filling stage, which is described with reference to Figure 2.
  • the tube 11 penetrates into the neck 42 of the bottle. It stops when its lower end reaches a level just less than the required future level of the liquid 4 which is to be transferred.
  • the roller 24 disengages from the cam 23.
  • the helical spring 26 extends, and the annular gasket 38 seals against the bottle neck 42 with an elastic pressure due to the action of the helical spring 22 which is compressed.
  • the ring gasket 35 disengages from the conical sealing surface 34 (see Figure 10), and the free vertical duct 15 connects the tank 2 to the interior of the bottle 5.
  • the liquid 4 flows into the bottle 5 by gravity, while the air and gas contained in the bottle reaches the top of the tank 2 via the tube 11.
  • the filling stage stops by virtue of the syphon trap 33 when the liquid has reached the end of the tube 11 within the bottle 5 and when the pressure of the liquid 4 and of the residual air within the top of the bottle neck are equal.
  • the syphon trap 33 By the effect of the pressure exerted upwards by the liquid the end of the tube 11 remains immersed in the liquid in the bottle, to hence determine a provisional level (Figure 3).
  • the closure of the delivery channel 15 is followed by the levelling stage, which is described with reference to Figures 5 and 13-15.
  • the stem 41 engaging the cam 41/1, opens the valve 39 and the pressurized inert gas 40/1 flows through the hose 37 to pass through the hole 36 into the end part of the vertical duct 15, and then into the bottle neck 42 to cause a back flow of liquid and gas which rises through the tube 11 as the annular duct 15 is closed above the hole 36 by the gasket 35 (see Figure 14).
  • the liquid level in the bottle falls and becomes stable when it coincides with the lower end of the tube 11.
  • the levelling stage is followed by the bottle exit, described with reference to Figures 6 and 16.
  • the cam 23 acts on the element 8 such as to separate the valve 1 from the neck 42 of the bottle 5, which is fed to a subsequent capping station.
  • valve 1 The components of the valve 1 are now arranged in a similar manner to that shown in Figure 1, so that the valve 1 is ready to operate on the next bottle 5.
  • the bottles remain at rest relative to the machine base during all the bottling stages. It is therefore not necessary for the bottling machine to be provided with cylinder-piston units for raising the bottle during the filling stage, as instead are required in the case of bottling machines provided with certain types of traditional filling valves.
  • the productivity of a bottling machine provided with a valve according to the invention is higher than a bottling machine of equal capacity but provided with traditional filling valves.
  • the filling valve of the invention is preferably used on machines which operate in a rotary manner about a vertical axis, and in which all the bottling stages take place in one of the angular sectors into which the machine is divided.
