Definitions

  • the invention relates to a filling valve for filling liquids according to the preamble of claim 1.
  • the filling material runs into the bottle with only a single inflow speed.
  • a filling speed is usually set above the static pressure level between the bottle and the filling level in the storage tank, which already leads to considerable qualitative losses in the filling pattern during the filling and filling phase of the filling process.
  • massive gas bubbles are hammered in, which can lead to the formation of a foam carpet for certain drinks (e.g. fruit juices).
  • the level of the product in the bottle rises so rapidly that there are deviations in accuracy when determining the level using a probe.
  • the object of the invention is to achieve an improvement in both filling methods and to allow the bottle to be filled more quietly, the usual speed control via throttles or nozzles, in particular in the case of pressure filling systems, to be dispensed with.
  • the influencing of the liquid flow flowing into the bottle in the filling system described below takes place via the stroke of the valve seat and thus via a throttling carried out in the valve seat by reducing the outlet cross sections leading into the bottle.
  • this is done by two pneumatic cylinders 1 and 2 arranged one above the other and working independently of one another.
  • the first cylinder 1 acts directly on the valve closing body 3, the liquid region 4 around the valve set 5 via a membrane 6 opposite the actuating element sealed and microbiologically protected.
  • This cylinder 1 opens and closes the fill valve seat and, when viewed alone, releases the maximum possible valve lift when opened.
  • the second pneumatic cylinder 2 arranged above the first cylinder 1 limits the stroke of the cylinder 1 in the pressurized state and thus narrows over the Valve stroke the outflow cross section 6 ', which the beverage must flow through on the way into the bottle 7.
  • the adjusting force of this cylinder 2 must be greater than the counterforce generated to open the valve seat 5 via the piston surface of the first cylinder 1. This is achieved with a pneumatic pressure that is set the same for both systems by a piston surface on the limiting cylinder 2 that is larger than the opening and closing cylinder 1.
  • the stroke limitation can be set individually with respect to the beverage and bottle via an adjusting ring 8.
  • the filling material runs into the bottle 7 at a low flow rate compared to the fully extended valve stroke.
  • the filling valve In addition to the two cylinders for opening and closing the valve seat 5, the filling valve also has another cylinder 9 which ventilates the filling tube 10 when it is emptied. All three addressed cylinders are controlled by only two solenoid valves 11, 12 from the electronic control. With the selected arrangement of the two solenoid valves 11, 12 in combination with a self-switching shuttle valve 13, all process steps of the entire filling process can be operated.
  • the configuration of the pneumatic connections for the actuating elements integrated in the filling valve saves an otherwise necessary third solenoid valve including its electrical control elements.
  • the bottle 7 is raised to the filling element via a lifting element 14. Sealing the bottle mouth from the filling element is not necessary in a long-pipe normal pressure filling system.
  • the control operates solenoid valve 11 and opens the valve seat.
  • the solenoid valve 12 is actuated so that the upper limiting cylinder 2 also moves into its lower end position and limits the opening stroke of the valve closing body 3 and thus immediately throttles the outlet cross section at the start of filling.
  • the first filling material now flows into the bottle with low flow and low turbulence at a low flow rate.
  • the gentle filling phase is continued until the filling tube is immersed in the liquid level.
  • the cylinder 15 for the filling tube emptying remains pressurized via both connections of the shuttle valve 13 and thus closed.
  • the electronic control 17 relieves the compressed air space of the limiting cylinder 2 via the solenoid valve 12 after the time preselected in the electronics for the filling phase, so that the latter moves to its upper end position by means of spring force.
  • the stroke limitation for the valve closing body 3 is thereby eliminated.
  • the full flow cross section is now available for the beverage flowing into the filling tube 10.
  • the filling of the cylindrical middle part of the bottle which is mostly uncritical in terms of filling technology, is now carried out with high throughput.
  • the duration of the quick fill phase can be freely adjusted for each bottle and drink using the computer control. In order to achieve high specific filling valve capacities, this filling phase is continued as far as possible into the bottle neck.
  • the upper pneumatic cylinder 2 presses the valve closing body again into its throttle position.
  • the filling speed goes back to the value of the filling phase.
  • the filling level now rises bubble-free in the bottle neck and cleanly covers the signal sleeve 18 on the filling tube 10, so that a corresponding filling level signal goes to the electronics.
  • solenoid valve 11 relieves the pressure on the lower pneumatic cylinder 1.
  • the cylinder piston closes the valve seat by means of spring force and ends the filling.
  • the changeover valve 13 connection that is continued from there is also depressurized.
  • the pressure still present via the solenoid valve 12 also keeps the filling tube emptying cylinder 15 closed in this phase.
  • the upper limiting cylinder 2 remains pressurized in its lower end position, in which, however, it no longer has any functional influence on the closed valve seat.
  • the fill level can be corrected to the desired fill quantity via a freely selectable time offset between the probe signal and the closing of the valve cone.
  • solenoid valve 12 Immediately when the lifting element detaches the bottle from the filling valve, solenoid valve 12 also drops and relieves the second connection on the shuttle valve 13.
  • the filling tube emptying cylinder 9 opens via spring force and vents the filling tube 10.
  • the beverage remaining in the filling tube 10 can now move into the downward moving one Drain the bottle.
  • the limiting cylinder 2 on the valve seat is now relieved of pressure and moves to its upper end position. After filling the filling point with the next bottle, the same procedure is repeated.
  • the pneumatically operated membrane valve 16 which is additionally arranged on the filling element, is used for purging the bottle with inert gas before the actual filling and for purging the bottle mouth with protective gas (microbiology). It has no influence on the actual filling process.
