Definitions

  • the present invention relates to a filling machine and, in particular, a filling machine for liquids using time-controlled dosing valves.
  • Filling machines for liquids are known and widely used, which use time-controlled dosing valves in order to produce the quantity of liquid to be introduced into each container.
  • the time necessary to fill each container is found experimentally by way of calibration operations and initial fine-tuning.
  • the value of the flow resistances is affected by multiple factors such as viscosity, density, temperature, centrifugal force in rotary filling machines, the geometry of the conduits, the level of the liquid, and the pressure in the supply tank.
  • the aim of the above invention was to ensure that the variations of the thermal/fluid dynamic parameters would not affect the initial calibration of the filling apparatus.
  • the solution in question discloses a filling machine with time-controlled dosing valves and having at least one master valve provided with an electronic flow meter which is connected to a computer unit, which manages the timing of the operations of dosed filling of at least one master bottle.
  • a throttling diaphragm is applied upstream of each valve which is calibrated with very high flow resistances in order to ensure that the relative variations of all the other parameters that could affect the repeatability of the operating conditions of the dosed flow will not affect such repeatability.
  • the aim of the present invention is to provide a filling machine that is capable of improving the known art in one or more of the above mentioned aspects.
  • an object of the invention is to provide a filling machine by which it is possible to manage the steps of calibration in a very practical manner.
  • Another object of the invention is to provide a filling machine that is highly reliable, easy to implement and at low cost.
  • the filling machine generally designated by the reference numeral 1, comprises a containment tank which is connected, by way of supply ducts, to a plurality of dosing valves 3, which are functionally connected to a device 10 for managing and controlling the opening and the closure of the above mentioned dosing valves 3.
  • the dosing valves 3 comprise at least one reference valve 3a, which is associated with a flow-rate measurement device 3b.
  • the filling machine 1 has a particularly high number of dosing valves 3, it is possible to have two or more reference valves 3a so as to be able to compensate for any malfunctions of one of such reference valves 3a.
  • the flow-rate measurement device 3b is functionally connected to the managing and controlling device 10 in order to determine the open time of the reference valve 3a that corresponds to the dispensing of a predetermined quantity of liquid.
  • the dosing valves 3 comprise a plurality of valves to be calibrated 3c.
  • the filling machine 1 is provided with a calibration station 11, which comprises at least one tray 20 into which the liquid dispensed by the at least one valve to be calibrated 3b can be discharged.
  • the tray 20 is associated, in particular, with a device for weighing the liquid discharged into the aforementioned tray 20 by the valve to be calibrated 3c in a time that corresponds to the open time of the reference valve 3a determined by the managing and controlling device 10.
  • the managing and controlling means 10 are adapted to detect the difference between the quantity of liquid discharged into the tray 20 by the valve to be calibrated 3c in a time that corresponds to the open time of the reference valve 3a determined by the managing and controlling device 10, and the aforementioned predetermined quantity of liquid.
  • the managing and controlling means 10 are functionally connected to the weighing device so that such means can automatically detect the difference between the quantity of liquid discharged into the tray 20 by the valve to be calibrated 3c in a time that corresponds to the open time of the reference valve 3a determined by the device for managing and controlling 10, and the aforementioned predetermined quantity of liquid.
  • the managing and controlling device 10 is adapted to generate a correction coefficient for the time that the respective valve to be calibrated 3c is to remain open as a function of such difference in order to allow the dispensing by the valve to be calibrated 3c, during use of the filling machine 1, of the aforementioned predetermined quantity of liquid.
  • the filling machine 1 comprises a plurality of valves to be calibrated 3c.
  • the filling machine 1 is provided with means for positioning, on command, each valve to be calibrated 3c in a calibration position in which the liquid that exits from the valve to be calibrated 3c is discharged into the at least one tray.
  • the tray 20 comprises a liquid discharge valve 21.
  • the filling machine 1 comprises a supporting structure 2 for a carousel 4 which can rotatingly move about a vertical axis 100.
  • the carousel 4 is provided, at its peripheral region, with the plurality of dosing valves 3.
  • the tray 10, and more generally the calibration station 11, is arranged along the movement trajectory of the dosing valves 3 and, more specifically, at a lower level with respect to that of the dosing valves 3.
  • the weighing device comprises a load cell.
  • the tray 20 can move on command between an operative position, in which it is arranged below the trajectory of the dosing valves 3 during the calibration operations, and an inoperative position in which it is arranged laterally with respect to the carousel 4 so as not to interfere with the bottles during filling during the normal use of the filling machine 1.
  • the filling machine 1 comprises a containment tank 2 which is connected, by way of supply ducts 2a, to a plurality of dosing valves 3 which are functionally connected to a device 10 for managing and controlling the opening and the closure of the dosing valves 3.
  • the filling machine 1 comprises a plurality of valves to be calibrated 3c.
  • the filling machine further has a calibration station 11, which comprises at least one tray 20 into which the liquid dispensed by the at least one valve to be calibrated 3c can be discharged.
  • the tray 20 is associated with a device for weighing the liquid discharged into the aforementioned tray 20 by the valve to be calibrated 3c in a time determined by the managing and controlling device 10.
  • the filling machine 1 of the type described above is also advantageously provided with means for positioning, on command, each valve to be calibrated 3c in a calibration position in which the liquid that exits from the valve to be calibrated 3c is discharged into the at least one tray 20.
  • the present invention relates to a method for calibrating dosing valves 3 of a filling machine 1, which comprises:
  • the method according to the invention entails a step of actuating the valve to be calibrated 3c for a time that corresponds to the open time of the reference valve 3a multiplied by the time correction coefficient and, optionally, a step of discharging the liquid dispensed during the step of actuating into the tray 10.
  • step of actuating there is a step of weighing to control the quantity of the liquid discharged into the tray during the step of actuating and a step of verifying the correspondence between the quantity of liquid discharged into the tray during the step of weighing to control the quantity of the liquid discharged into the tray and the predetermined quantity of liquid.
  • the method comprises, in succession, a plurality of single steps of opening the valve to be calibrated for a time that corresponds to the open time of the reference valve 3a, and a plurality of respective steps of detecting, by the managing and controlling device, the difference between the quantity of liquid discharged into the tray and the predetermined quantity of liquid.
  • the managing and controlling device is adapted to determine the time correction coefficient, if the single quantities of liquid detected in the respective steps of detecting show a percentage deviation with respect to each other that is within the limit that can be preset.
  • step of generating there is also the step of calculating the average value of the single quantities of liquid detected.
  • the step of generating, by the managing and controlling device 10, the open-time correction coefficient uses, in particular, such average value.
  • the method entails a step of emptying the tray 20 when a limit level is exceeded.
  • the present invention relates to a method for calibrating dosing valves 3 of a filling machine 1, which comprises:
