Definitions

  • the present invention relates to a filling valve and a method for filling a container.
  • the present invention refers in particular to the food sector, in which filling machines are used, i.e. machines for filling a plurality of containers with a fluid product, in particular liquid or semi-liquid.
  • Filling machines generally comprise a carrousel provided with a plurality of filling valves, each of which is activated and deactivated during the movement of the valve itself integrally with the carrousel.
  • Each filling valve ordinarily comprises a shutter that is movable between an open position and a closed position, being able to assume also intermediate positions, to throttle the flow of product introduced into the containers during the filling operation.
  • the reduction of the opening of the valve in the initial phase has the purpose of preventing turbulence in the filling fluid.
  • the purpose of reducing the opening of the valve in the initial phase is to prevent undesired releases of fluid from the container and to make the dosing of the product more precise.
  • the purpose of completing the intermediate filling phase with the valve in the position of maximum opening is to minimise filling times.
  • the initial and final phases are determined according to the type of filling fluid and of container to be filled, i.e. according to parameters for setting the filling process. For example, for a given fluid and a given container, it may be desirable to perform the filling operation with the valve in throttled position until the container is 10% full, subsequently with the valve completely open until the container is 90% full and, subsequently, with the valve throttled until the completion of the filling operation.
  • a flow rate sensor is used, active on the outflow conduit of the valve.
  • the intermediate position of the shutter may be varied as well.
  • filling valves are provided with one or, in some cases, with a plurality of throttled positions, to enable, during the filling operation, to vary the position of the shutter between pre-set positions according to a predetermined logic.
  • filling valves according to said prior art solutions comprise an actuator, to actuate a piston connected to the shutter movable between the position of maximum opening and the closed position, and control means connected to the actuator to regulate the position of the piston according to the flow rate valves measured by the sensor.
  • Filling systems in use do not allow to regulate the position of the shutter (i.e. of the piston) with continuity and precisely, in order to vary the opening of the valve according to any pattern, according to the type of container and of filling fluid.
  • An object of the present invention is to eliminate the aforesaid drawbacks and make available a filling valve that enables to carry out the filling operation in optimised, particularly efficient fashion.
  • valve of the present invention which is characterised by the content of the appended claims and in particular in that the control means comprise an element for detecting the position of the piston connected to the actuator to regulate the position of the piston in feedback, comparing the measured position with a pre-set position as a function of the measured value of flow rate and consequently modifying the position of the piston.
  • control means comprise an element for detecting the position of the piston connected to the actuator to regulate the position of the piston in feedback, comparing the measured position with a pre-set position as a function of the measured value of flow rate and consequently modifying the position of the piston.
  • figure 2 shows a function diagram of the valve of figure 1
  • FIG. 3 shows the valve of figure 1 according to an embodiment variant.
  • BEST MODE FOR CARRYING OUT THE INVENTION designates a filling valve according to the present invention.
  • the valve 1 is able to be inserted in a filling machine, to insert a filling fluid into a container.
  • the valve 1 comprises a shutter 2 connected to a piston 3 to open and close a conduit 4 for the outflow of the filling fluid from the valve 1.
  • the piston 3 is movable with continuity between a position of maximum opening and a closed position of the conduit 4.
  • the valve 1 also comprises an actuator 5 to actuate the piston 3 with continuity between the closed position and the position of maximum opening of the valve 1, and vice versa.
  • the actuator 5 is pneumatic.
  • the piston 3 is preferably a single action piston co-operating with a spring 6.
  • the spring 6 forces the piston 3 to remain in the closed position, or, alternatively, in the fully opened position, in the absence of actions by the actuator 5.
  • the actuator blowing in air, actuates the piston 3 towards the open or, alternatively, the closed position, contrasting the action of the spring 6.
  • the valve 1 has not end stops able to define intermediate positions of the piston 3, i.e. the piston 3 is free to slide without obstacles assuming all positions between the closed and the fully opened position.
  • valve 1 comprises a sensor 7 (not shown in figure 1, but shown schematically in figure 2) to measure values of flow rate of the fluid delivered by the valve.
  • Said sensor 7, of a substantially known kind is preferably inserted in the conduit 4 for the outflow of the filling fluid.
  • the filling valve also comprises a board 8, able to receive at its input a signal representing the flow rate value measured by the sensor 7 and to derive (substantially by means of a time integration process) the quantity of product (i.e. of filling fluid) present within the container at a given instant.
  • the board 8 is analogue.
  • the board 8 is programmed to associate to the flow rate values received at its input corresponding desired values of opening of the valve 1, i.e. desired positions for the shutter 2 (or for the piston 3).
  • the board 8 is operatively connected to the actuator 5 to drive it, on the basis of said desired values of opening for the valve 1, obtained as a function of the flow rate values received as inputs.
  • the board 8 comprises a memory containing at least one preset pattern of the position of the piston 3 as a function of the quantity of filling fluid inserted in the container.
  • said memory comprises a plurality of preset patterns; moreover, the board 8 is provided with means for selecting one of said patterns as a function of the filling fluid (constituted, for example, by a logic integrated in the board 8 or by an appropriately programmed PLC).
  • the valve 1 also comprises, originally, an element 9 for tracking the position of the piston 3. Said tracking element 9 is connected to the board 8 and hence, through the board 8, it is operatively connected to the actuator 5 to regulate the position of the piston 3 in feedback, i.e. on the basis of a comparison between the measured position of the piston 3 and said desired position.
  • said desired position is obtained as a function of the measured flow rate value, on the basis of a pre-set pattern of the position of the piston 3 as a function of the quantity of filling fluid inserted in the container, said pattern being selected from a plurality of patterns.
  • the board 8 sends a command signal to the actuator to actuate the piston according to the result of said comparison between the measured position of the piston and its desired position (for the instantly measured flow rate value).
  • the board 8, the sensor 7 and the tracking element 9 define control means 10 connected to the actuator 5 to regulate the position 3 of the piston as a function of the flow rate values measured by the sensor.
  • Said tracking element 9 is constituted, for example, by a linear transducer operatively connected to the piston 3 (e.g. a feeler pin).
  • the tracking element 9 and the actuator 5 are mutually integrated, in the form of an electrical positioner. Note that electrical positioners, in themselves, are known in the sector of monitoring the level of liquid present within tanks.
  • control means 10 in general and, in particular, the board 8, they are constructed in analogue or, alternatively, in digital fashion.

  • the first portion and the second portion interact electrically (e.g. by means of a potentiometer), optical or magnetic, making available an electrical output signal representative of the position of the piston 3 relative to a fixed portion of the valve 1.
  • the board 8 is an electronic board connected to the tracker 9 and to the electrical valve to control in feedback the position of the piston 3, the board 8 constituting at the same time said control means 10.

  • the present invention is particularly flexible, with the possibility of treating filling fluids and different containers in optimised, automatic fashion with no need for regulation and calibration operations.
