Definitions

  • the present invention relates to a filling machine of the weight filling type, and more precisely to a system for refilling the filling liquid in the supplying tank of the machine.
  • Filling machines typically comprise a carousel which moves a plurality of containers to be filled and a plurality of filling taps, placed on the vertical axis of the containers, adapted to dispense the filling liquid into the containers.
  • the tank tends to empty, and the level to decrease, which would alter the filling speed. Therefore, the tank comprises a refill system, which is adjusted so as to maintain the level of liquid in the tank substantially constant at all times.
  • a refill system is complex and requires the use of sophisticated detection means, such as level sensors and/or command and control units adapted to adjust the refilled liquid amount as a function of that dispensed by the machine.
  • the invention relates to a weight filling machine comprising a filling unit and a unit for supplying a container-filling liquid to the filling unit, wherein the supply unit comprises a tank containing the filling liquid from which a dispensing duct departs, wherein the dispensing duct leads into an automatic refill device comprising a receptacle in turn connected to the filling unit by means of a supply line of the filling liquid, wherein the dispensing duct terminates inside the receptacle with an automatic valve, preferably a float valve, for closing-opening the dispensing duct, wherein the automatic valve determines and adjusts the level of filling liquid inside the receptacle.
  • the supply unit comprises a tank containing the filling liquid from which a dispensing duct departs
  • the dispensing duct leads into an automatic refill device comprising a receptacle in turn connected to the filling unit by means of a supply line of the filling liquid
  • the dispensing duct terminates
  • the filling machine indicated as a whole by numeral 1, comprises a filling unit 2 and a supply unit 3 of a liquid product for filling containers.
  • the filling unit 2 comprises a rotating table 4 hinged on a shaft 5 moved by the motorization of the machine.
  • the rotating table 4 comprises a plurality of plates 6 for supporting containers C.
  • the containers C may be retained on the plates 6 in a conventional manner, for example by retaining them at the neck 7 by means of suitable pliers.
  • the plurality of distribution lines 9 is connected to a distribution manifold 10 which distributes the product among the various filling valves 8.
  • the constructional details of the distribution manifold 10 are known to those skilled in the art since such a manifold is used in conventional filling machines.
  • the supply unit 3 comprises a tank 12 containing the filling liquid.
  • the tank may be periodically filled by means of a loading line 13 which may be connected to a tank or storage silos, for example.
  • Tank 12 comprises a dispensing duct 14, typically placed at the bottom to allow the outflow of the liquid by gravity.
  • the dispensing duct 14 leads into an automatic refill device 15, in turn connected along with the supply line 11 of the filling liquid to the distribution manifold 10 of the filling unit 2.
  • the automatic refill device 15 in particular the surface of the liquid inside such a device, is placed at a lower height with respect to the level at which the dispensing nozzles of the filling valves 8 are placed. As shown in Figure 1 , the filling liquid should thus overcome a geodetic difference in level h1 so that the dispensing of the liquid may take place. This feature allows to obtain a better control of the filling operation.
  • the automatic refill device 15 is preferably placed on the floor.
  • the automatic refilling device 15 comprises a receptacle 16, the supply line 11 of the filling unit 2 departing from the bottom thereof.
  • Receptacle 16 may have a cylindrical shape, but other shapes, such as an ovoid shape or a spherical shape, are not excluded.
  • the float valve 17 thus defines the level of liquid present in receptacle 16.
  • Receptacle 16 then comprises a headspace 20 which remains free at all times from the filling liquid.
  • receptacle 16 comprises an opening 21 connected to a pipe 22 in flow communication with a source 23 of air or another gaseous fluid (e.g., an inert gas if the filling liquid is sensitive to oxygen) at a first predetermined pressure P1.
  • a source 23 of air or another gaseous fluid e.g., an inert gas if the filling liquid is sensitive to oxygen
  • the pressure P of the filling fluid exiting the dispensing duct 14 is higher than the first pressure P1 of the gas in the headspace 20, but lower than a second pressure P2 given by the sum of the first pressure P1 of the gas with Archimedes' thrust to which the float 19 is subjected.
  • the pressure P of the fluid exiting the dispensing duct 14 is determined by pumping means 24 for loading the filling liquid in receptacle 16.
  • valve means 25 are placed, typically a pressure limiter, connected to a recirculation duct 26 which reconnects to the dispensing duct 14 upstream of the pumping means 24.
  • valve means 25 would divert the liquid flow into the recirculation duct 26.
  • the filling machine according to the invention allows to achieve the intended objects.
  • the automatic refill system of the invention does not require sophisticated electronic controls, such as level sensors and the like, thus obtaining the adjustment of the level in the refill device 15 in a totally mechanical manner.
  • the machine of the invention is of simple design and easy maintenance.
