Definitions

  • the invention is based on a method for filling containers with a pressurized liquid according to the preamble of claim 1.
  • a method for filling containers with a pressurized liquid according to the preamble of claim 1.
  • Such a method has already become known from JP 10 46 392 B4.
  • the liquid pressure is measured once after opening a filling valve, whereupon a control device calculates a filling time or opening time for the filling valve for a specific filling quantity on the basis of the measured liquid pressure.
  • a disadvantage of the known method is that pressure fluctuations occurring during the filling process, which lead to a change in the flow rate at the filling valve, are not taken into account. Furthermore, the filling quantities are not taken into account during the opening and closing process of the filling valve. The accuracy of the known filling method is therefore limited.
  • the inventive method for filling containers with a pressurized liquid with the characterizing features of claim 1 has the advantage that it works very precisely. This is achieved according to the invention in that the liquid pressure is continuously measured during the filling process, so that pressure fluctuations that occur are taken into account. Furthermore, the flow can psychrned of the opening and closing operation detected the filling valve, and in which the filling volumes B ALCULATION be considered. Further advantages and advantageous developments of the method according to the invention for filling containers with a liquid under pressure result from the subclaims and the description.
  • the filling machine shown in FIG. 1 for dosing and filling a liquid into packaging container 10 has a conveying device 11 with which packaging containers 10, such as ampoules or vials, are fed to treatment stations arranged one behind the other.
  • the conveyor 11 has a transport screw 12 for the cyclical or continuous transport of the packaging container 10.
  • the packaging containers 10 stand and slide on rail sections 13 to 15. Between the rail sections 13 and 14 or 14 and 15, a weighing device 17, 18, which can be controlled via a discharge device 16, is arranged for each packaging container 10, of which one 17 the tare weight Eq, and the other 18 detects the gross weight G2 of the packaging container 10 and supplies it to a control device 19 as an input variable.
  • control device 19 for example, product-specific data, such as the viscosity profile of the liquid over the temperature and data of the device, are stored.
  • An input / output unit 20 is connected to the control device 19, via which in particular one Desired filling quantity M or a desired filling weight of the packaging container 10 can be entered into the control device 19.
  • the filling device 22 comprises a number of filling heads 23, for example six, corresponding to the number of packaging containers 10 to be filled per conveying cycle, each of which has a hollow filling needle 24 which can be moved up and down.
  • Each filling head 23 is coupled to a metering valve 25 for the liquid, wherein all metering valves 25 can be controlled synchronously by the control device 19 together.
  • the metering valves 25 are connected via short lines 26 to a common, tubular distributor 30 in which a liquid pressure Pl prevails.
  • the distributor 30 is in turn connected via a line 33 and a quick release device 34 to a storage container 35 for the liquid.
  • the pressure drop between the distributor 30, which is completely filled with the liquid, and the individual metering valves 25 is always the same, for example due to an arrangement of the metering valves 25 at the same vertical distance from the distributor 30, and is stored in the control device 10 as a factor.
  • the storage container 35 advantageously contains the amount of liquid that is required during a production shift to fill the packaging containers 10. The result of this is that the filling level in the storage container 35 only decreases to a very small extent in each filling cycle.
  • the reservoir 35 is pressurized with a gas pressure P2 via a pressure line 36.
  • the pressure P2 generally enables a higher pressure of the liquid at the metering valves 25, and thus a high outflow rate from the storage container 35, which promotes the flow behavior in particular in the case of highly viscous liquids.
  • a temperature sensor 31 for detecting a liquid temperature T and a pressure sensor 32 for are in the distributor 30
  • the two sensors 31, 32 are also connected to the control device 19.
  • the liquid pressure Pl continuously at certain time intervals ⁇ t, for example every 150 ⁇ sec. until every 250 ⁇ sec. measured, and the control device 19 is supplied as an input variable.
  • the duration of the time intervals .DELTA.t between the individual measurements of the liquid pressure Pl should be chosen so that 25 liquid pressures Pl are detected even during the opening and closing process of the metering valves and are forwarded to the control device 19. For these reasons, there has been a value for ⁇ t of 200 ⁇ sec. proven that ensures sufficient resolution even during the opening and closing process of the filling valves 25.
  • the device described above works as follows: The packaging containers 10 are fed by the conveyor screw 21 to the filling device 22 in cycles. As soon as a packaging container 10 under its assigned Filling head 23 is positioned, the filling needles 24 of the filling heads 23 are lowered and inserted into the packaging container 10. At the same time, the control device 19 initiates the filling of the desired filling quantity M into the packaging container 10 by a corresponding control signal Z to the metering valves 25, ie the control signal Z causes, for example, energization of a coil in the metering valve 25 so that its needle lifts off the valve seat.
  • the calculation of the filled quantity M (ist), and thus the duration of the control signal Z to the metering valves 25, is carried out by the control device 19 continuously calculating partial volumes ⁇ M and adding them up during the duration of the control signal Z.
  • the partial volumes ⁇ M are calculated from the time intervals ⁇ t between the individual measurements of the liquid pressures Pl, the value of the liquid pressure of Pl supplied to the control device 19, and a functional relationship k (pl) stored in the control device 19 between the respective value of Pl and the result thereof in the metering valves 25 resulting flow rate per unit time.
  • the control device 19 thus calculates the filling quantity M (actual) filled into a container 10 according to the following formula:
  • this limit value M (max) which causes the control signal Z to end, is the desired filling quantity M itself.
  • the limit value M (max) stored in the control device 19 can be corresponding to the However, the closing characteristics of the filling valves 25 can also be selected to be smaller, so that, for example, the filling quantity or the partial volumes ⁇ M that enter the containers 10 during the closing process (after the control signal Z has failed) of the metering valves 25 are also taken into account. This means that in this case the limit value M (max) is smaller than the target filling quantity M.
  • the accuracy of the partial volume calculation ⁇ M of the control device 19 is increased by taking into account the temperature T of the liquid detected by the temperature sensor 31. This is achieved in that the flow / viscosity characteristics for the respective liquid are stored in the control device 19, so that the corresponding temperature-corrected functional relationship k is additionally accessed for calculating the individual partial volumes ⁇ M, i.e. that the value of the factor k also depends on the temperature [k (Pl, T)].
  • the filling needles 24 are lifted out of the packaging containers 10 again by the filling heads 23.
  • the packaging containers 10 are then conveyed by the screw conveyor 12 to another processing station, for example a closing station, in cycles. At the same time, the process is repeated as described above for packaging containers 10 that are newly conveyed into the filling machine.
  • Packaging container 10 from the control device 19 to determine a correspondingly corrected control signal Z for the metering valves 25.

Abstract

Une machine de remplissage destinée à transvaser un liquide dans des récipients (10) présente, pour chaque récipient (10), une vanne de remplissage (25) qui est actionnée par un dispositif de commande (19), au moyen d'une impulsion de commande (Z). Afin accroître la précision de la quantité de liquide M (réel) à transvaser dans le récipient (10) par rapport à une quantité de remplissage théorique (M), il est prévu que le dispositif de commande (19) totalise des volumes partiels ( DELTA M) déterminés en fonction des pressions mesurées (P1) du liquide, des intervalles de temps ( DELTA t) entre les différentes mesures de pression et d'une caractéristique pression/passage de liquide à travers la vanne de remplissage (25). Dès que la somme des volumes partiels ( DELTA M) dépasse une quantité de remplissage limite (M (max)), le dispositif de commande (19) interrompt le signal de commande (Z).
