Definitions

  • the present invention relates to a method for filling containers with a filling product in a filling product filling plant.
  • the filling valve provides a connection between the filling product reservoir, in which the filling product to be filled is provided before the actual filling, and the container to be filled.
  • the filling process is initiated and passed the filling product in the container to be filled and after reaching a certain specification, for example, after reaching a predetermined filling weight, a predetermined filling level or a predetermined filling volume, the filling process ends again.
  • Filling valves are known by means of which only opening and closing of the respective connection between the filling product reservoir and the container to be filled is achieved. This simple switching filling valves is often preceded by a throttle device by means of which a modulation of the filling product flow can be achieved in the container to be filled.
  • filling valves which are also referred to as proportional valves, in which the respective Greephgel over its filling valve seat in stages or continuously can be raised or lowered, which can be varied according to the forming between the Greephgel and the Greephrine gap or annular gap in its cross section. Accordingly, in such a proportional valve, a variation of the effective cross section and thus also a variation of the filling product flow flowing through the proportional valve can be achieved. This makes it possible with the proportional valve to specify or control a predetermined volume flow profile for the filling of each container to be filled.
  • Proportional valves are often coupled in a closed loop with a flow meter associated with this proportional valve. In this way it is possible by means of the combination of flow meter and proportional valve from a higher-level system control to specify a volume flow, which is then held over the control loop.
  • both the flow meter and the corresponding evaluation device and the control of the proportional valve involve a certain inertia and time delay, so that an immediate response to changes in the initial conditions and in particular changes in the supply of the filling product to the proportional valve only with a certain
  • Time delay can be corrected. Furthermore, flow meters are often dependent on the properties of the respective filling product.
  • each filling valve is connected directly to the Art.
  • the filling product reservoir acts as a buffer, such that each filling valve, and in particular each proportional valve, is independent of the other filling valves

  • the lower inertia of the differential pressure measurement it is possible to respond more quickly to a change in the differential pressure within the device, which is usually due to the fact that additional filling valves connected in parallel are switched on or off.

  • a predetermined by the filling process for the respective filling product and the respective container to be filled volume flow profile is controlled, for example via their respective individual flow meters, to the given volume flow profile. Accordingly, the respective filling valve is adjusted to a predetermined opening value, which is assumed to correspond to the corresponding volumetric flow rate predetermined by the volumetric flow profile, and then regulated precisely to this value via the respective flowmeter.
  • This control of the filling valve by means of the predetermined volume flow profile is superimposed by the control and / or control means of the proposed method, which allows compensation of the filling product flow in the container to be filled due to the determined differential pressure.
  • the corresponding filling valve can be controlled to the appropriate position, which is derived from the volumetric flow profile compensated by the calculated volumetric flow based on the determined

  • a control over a change in the flow rate by means of the flow meter would require a control time of approximately 50 milliseconds.
