Definitions

  • the present invention relates to a device and a method for filling a container to be filled with a filling product, for example in a beverage bottling plant.
  • Filling methods and devices for carrying out a filling method are known, in which a container to be filled is sealed with a treatment chamber, a filling valve is connected to the mouth of the container to be filled and the interior of the container to be filled is flushed with a flushing gas to reduce the oxygen content. After the interior of the container has been flushed with the flushing gas, the interior of the container is then filled with the filling product.
  • the container to be filled can also be prestressed or evacuated before filling.
  • the treatment chamber is pressurized and then the filling valve is removed from the mouth of the container already filled with the filling product. Due to the overpressure present in the treatment chamber, when the filling valve is removed from the mouth of the container filled with the filling product, there is no overflowing, splashing out or foaming over, in particular of a carbonized filling product.
  • the treatment chamber which is under the overpressure, communicates accordingly with the interior of the container.
  • a container closure is then applied to the container in the treatment chamber, which is still under overpressure, and the container is closed accordingly.
  • the following is the one present in the treatment chamber Overpressure reduced to essentially ambient pressure and then the filled and sealed container removed from the treatment chamber.
  • Such a device and such a method are, for example, from EP 2 937 310 A2 known.
  • Other generic devices and methods are in the documents WO2017/135902A1 , DE102014105974A1 and DE102014102953A1 described.
  • the pressure level in the treatment chamber enclosing the container is recorded with a pressure sensor, since the pressure, in particular the level of the overpressure present in the treatment chamber, is decisive for successful filling and sealing.

This is the case in particular when the component and its drive can in principle be moved freely by the pressure introduced into or present in the treatment chamber and the drive must accordingly apply a holding force to hold the position of the components. This holding force is correspondingly expressed by the manipulated variable to be applied.
  • the holding force to be applied increases with the pressure present in the treatment chamber.
  • the manipulated variable of the drive is already determined for drive-related reasons, for example for the purpose of controlling the drive, it may be the case that essentially no additional parts need to be provided on the device in order to determine the pressure in the treatment chamber can. In other words, a separate pressure sensor can then be dispensed with.
  • control and “control” and “control” include both controlling and regulating in the sense of automation technology.
  • the pressure that is present in the treatment chamber and can be determined by means of the pressure determination unit is determined in accordance with the ambient pressure that acts on the movable component outside of the treatment chamber. In other words, the pressure determination unit determines a differential pressure between the ambient pressure and the pressure present in the treatment chamber.
  • the pressure in the treatment chamber can correspondingly be an overpressure compared to the ambient pressure if the treatment chamber is subjected to a pressurized gas under overpressure, for example.
  • the pressure can be present, for example, at an absolute pressure of 2 bar to 11 bar, ie a relative overpressure of 1 bar to 10 bar compared to the ambient pressure.
  • the pressure in the treatment chamber can also be a negative pressure compared to the ambient pressure if the treatment chamber is connected to a vacuum line, for example, by means of which the gas present in the treatment chamber is drawn off.
  • the pressure in the treatment chamber can be, for example, at an absolute pressure of 0.1 bar to 0.9 bar are present, i.e. a relative negative pressure of 0.1 bar to 0.9 bar compared to the ambient pressure.
