Definitions

  • the invention is based on a method for filling Containers with a liquid under pressure the genus of claim 1. From JP 10 46 392 B4 Such a method has already become known. At This procedure uses the fluid pressure after opening of a filling valve measured once, whereupon a Control device based on the measured Liquid pressure a filling time or opening time for the Filling valve calculated for a certain filling quantity.
  • a disadvantage of the known method is that during the Filling process occurring pressure fluctuations that lead to a Do not change the flow rate at the filling valve be taken into account. The fill quantities also remain during the opening and closing process of the filling valve disregarded. The accuracy of the known Filling process is therefore limited.
  • the method according to the invention for filling containers with a pressurized liquid with the characteristic features of claim 1 has in contrast the advantage that it works very precisely. This will achieved according to the invention in that the liquid pressure is constantly measured during the filling process, so that occurring pressure fluctuations are taken into account.
  • the flow rates during the Opening and closing process of the filling valve is detected, and be taken into account when calculating the filling volumes.
  • the Conveying device 11 has a screw conveyor 12 for intermittent or continuous transport of the Packaging container 10 on.
  • the packaging container 10 stand and slide on rail sections 13 to 15. Between the rail sections 13 and 14 or 14 and 15 one controllable via a reject device 16 Weighing device 17, 18 for one packaging container each 10 arranged, one of which 17 the tare weight G1, and the other 18 the gross weight G2 the Packaging container 10 detected and a control device 19th as input variable.
  • control device 19 are, for example product-specific data, such as the viscosity curve of the Fluid over temperature as well as device data saved.
  • product-specific data such as the viscosity curve of the Fluid over temperature
  • device data saved With the control device 19 is an input / output unit 20 connected, in particular a Target filling quantity M or a target filling weight of Packaging container 10 to the control device 19th can be entered.
  • the Filling device 22 includes a cyclical transport the packaging container 10 one of the number of each conveying cycle to be filled packaging container 10 corresponding number of Filling heads 23, for example six, each one on and have removable hollow filling needle 24. Every filling head 23 is with a metering valve 25 for the liquid coupled, with all metering valves 25 of the Control device 19 can be controlled synchronously together.
  • the metering valves 25 are connected to a via short lines 26 common tubular manifold 30 connected in the one Liquid pressure P1 prevails.
  • the distributor 30 is in turn via a line 33 and a Quick release device 34 with a storage container 35 for the liquid connected.
  • the pressure drop between the with the liquid fully filled manifold 30 and individual metering valves 25 is, for example, by a Arrangement of the metering valves 25 in the same vertical Distance to the distributor 30 always the same size, and in the Control device 10 stored as a factor.
  • the reservoir 35 is a Pressure line 36 is pressurized with a gas pressure P2.
  • Pressure P2 generally increases the pressure Liquid at the metering valves 25, and thus a large one Outflow rate from the reservoir 35 enables which is especially the case with highly viscous liquids Flow behavior favors.
  • a temperature sensor 31 for detection is in the distributor 30 a liquid temperature T and a pressure sensor 32 for Detection of the liquid pressure P1 arranged.
  • the two Sensors 31, 32 are also connected to the control device 19 connected.
  • the liquid pressure P1 continuously at certain time intervals ⁇ t, for example every 150 ⁇ sec. until every 250 ⁇ sec. measured, and supplied to the control device 19 as an input variable becomes.
  • the duration of the time intervals ⁇ t between the individual Measurements of fluid pressure P1 should be chosen this way be that even during the opening and closing process of the metering valves 25 detects liquid pressures P1, and on the control device 19 are forwarded. From these For reasons there is a value for ⁇ t of 200 ⁇ sec. proven, the adequate resolution even during opening and Closing process of the filling valves 25 guaranteed.
  • the device described above works as follows:
  • the packaging container 10 are from the screw conveyor 21 fed to the filling device 22 in cycles.
  • the filling needles 24 of the Filling heads 23 lowered and into the packaging container 10 introduced.
  • a corresponding Control signal Z to the metering valves 25 through the Control device 19 the filling of the target filling quantity M in the Packaging container 10 initiated, i.e. the control signal Z, for example, energizes a coil in the Metering valve 25 so that its needle lifts off the valve seat.
  • the calculation of the filled filling quantity M (ist), and thus the duration of the control signal Z to the metering valves 25 takes place in that the control device 19th continuous partial volumes ⁇ M calculated and during the duration of the control signal Z are added up.
  • the partial volumes ⁇ M are calculated from the time intervals ⁇ t between the individual measurements of the liquid pressures P1, the respective the value supplied to the control device 19 Fluid pressure of P1, as well as one in the Control device 19 stored functional relationship k (p1) between the respective value of P1 and the resulting value in the Dosing valves 25 resulting flow rate per Time unit.
  • This limit value M (max) which causes the control signal Z to end, is in the simplest case the desired filling quantity M itself.
  • the limit value M (max) stored in the control device 19 can also be selected to be smaller in accordance with the closing characteristics of the filling valves 25, so that for example, the filling quantity or the partial volumes .DELTA.M are also taken into account that enter the containers 10 during the closing process (after the control signal Z has failed) of the metering valves 25. This means that in this case the limit value M (max) is smaller than the target filling quantity M.
  • Control device 19 The accuracy of the partial volume calculation ⁇ M Control device 19 is by taking into account the Temperature sensor 31 detected temperature T of the liquid elevated. This is achieved in that Control device 19 for the flow / viscosity characteristics the respective liquid are stored so that for Calculation of the individual partial volumes ⁇ M additionally on the corresponding temperature-corrected functional context k is accessed, i.e. the value of factor k is also depends on the temperature [k (P1, T)].
  • the filling needles 24 are introduced through the Filling heads 23 again from the packaging containers 10 lifted out. Then the packaging container 10 by the conveyor screw 12 cyclically another Processing station, for example a sealing station, promoted. At the same time repeats itself for new in the Filling machine conveyed packaging container 10 the process as described above.
  • the value is sufficient of the liquid pressure P1 only during the actual one Filling process. Usually and for Control purposes in the event of any malfunction of the Filling machine, however, the fluid pressure P1 becomes constant measured and fed to the control device 19.
  • the time intervals ⁇ t it is also conceivable for the time intervals ⁇ t to be so large to choose that the opening and closing of the Dosing valves 25 with respect to the partial volumes ⁇ M no longer is taken into account exactly, and in this case for opening and closing the metering valves 25 fixed partial volumes ⁇ M (fixed) (according to the metering valve characteristics) to assume. Even in this case, the accuracy improved compared to known filling methods because Pressure fluctuations during the actual filling be taken into account.
