Definitions

  • the present invention relates to a filling member for filling a filling product into a container, preferably for filling a beverage in a beverage filling plant.
  • filling organs for filling a filling product are known in a container in which a filling valve is provided, by means of which a Greet is opened and closed.
  • the filling process for filling the container with the filling product is started and ended via the filling valve, so that the predetermined filling product volume, the predetermined filling weight and / or the predetermined filling level in the container to be filled is achieved.
  • Various control and / or regulating mechanisms are known for this purpose, for example via the determination of a filling weight, via the determination of a filling level by means of a fill level probe and / or the determination of a filling volume, for example via a flow meter.
  • the filling product flow which flows through the filling valve into the container to be filled can be controlled or regulated in order to provide a filling product stream adapted to the respective filling state of the container to be filled and appropriate to the respective filling product.
  • a maximum filling speed is achieved by a maximum product flow.
  • the filling process is to achieve the highest possible accuracy of the respective filling target, for example, to achieve a predetermined filling product volume, a predetermined filling weight and / or a predetermined filling level, in turn filled with a reduced filling product stream.
  • the filling valve and the throttle valve known filling members are usually controlled by two separate control drives.
  • a throttle valve diaphragm valves for example, are common, whereas filling valves are often formed in the form of an axially out of a Greinering Bath Bath, which are actuated according to different control drives.
  • a filling valve is known in which by two different movements, which are applied via two different drives, a filling valve and a throttle valve are controlled.

  • both valves can be driven by a common drive, whereby the complexity and the shape factor of the filling further reduced.
  • the filling valve and the throttle valve are actuated separately from each other by means of the one control element and are preferably successively and / or independently operable.
  • the possibility of separate operation the entire functionality of the filling member is maintained even when using only one control.
  • the knowledge is used that only the throttle valve for flow control must be actuated during the filling process with fully open filling valve, but can be dispensed with an actuation of the opening state of the filling valve in this phase.
