Definitions

  • the invention relates to a filling element for filling bottles or similar containers with a liquid filling material according to the preamble of patent claim 1 and to a filling machine of the rotating type according to the preamble of patent claim 10.
  • Filling elements for filling bottles or similar containers with a liquid product are known in different designs, and also as filling elements for volume-controlled filling (volumetric filling).
  • a flow meter is provided in a liquid line between a source of the liquid filling material (e.g. storage container or boiler) and the respective filling element, which transmits a measurement or control signal to a central control device (computer) that causes the completion of the filling process, i.e. the closing of the liquid valve ) the filling machine delivers.
  • Such filling elements are provided on filling machines that have a large number of treatment stations or positions, which can also be understood as filling stations or filling positions.
  • a filling element or filling element with a filling valve or liquid valve is provided, via the discharge opening of which the liquid filling material is discharged into the container.
  • the filling material is dispensed into the container by means of what is known as “free jet filling”.
  • free-jet filling or “free-jet filling” is understood to mean a filling process in which the liquid filling material flows towards the container to be filled from the liquid valve in a free filling jet or filling material jet, the flow of the filling material not passing through guide elements such as deflection screens, swirl bodies , short or long filling tubes is influenced or changed. Free jet filling can take place both without pressure and under pressure. In the case of pressureless free-jet filling, the container has ambient pressure, the container generally not resting against the filling element with its container mouth or opening, but rather against the filling element or a dispensing opening provided is spaced.
  • a gas path creates a connection between the interior of the container and the environment, which enables pressureless filling.
  • the gas contained in the container and displaced by the beverage flowing into the container preferably also escapes into the surroundings via this gas path.
  • the opening of the container is pressed against the filling element and sealed; the pressure in the interior of the container is adjusted to this pressure, which differs from the ambient pressure, by applying a tension gas or by applying a negative pressure which can be both above and below ambient pressure.
  • a filling element for filling bottles or similar containers with a liquid filling material has also been proposed, with a liquid channel formed in a housing of the filling element, which has a connection to be connected to a source for the liquid filling material and a dispensing opening for the delivery of the liquid filling material forms a container to be filled and has a liquid valve with a valve body interacting with a valve seat between the connection and the dispensing opening.
  • the valve body can be moved by an actuating element for opening and closing the liquid valve, specifically for controlling the filling process as a function of a flow meter, which uses a measuring mechanism to detect the flow rate that flows through a section of the liquid channel forming a measuring channel. If a pneumatic drive is used as the actuating element, the adaptation of the actuating element for opening and closing the liquid valve to different container sizes and container geometries is often complex and therefore costly.
  • the object of the invention is to provide a filling element for filling bottles or similar containers with a liquid filling material, in which the filling element can be easily adapted to different container sizes and container geometries.
  • This object is achieved by a filling element for filling bottles or similar containers with a liquid filling material according to the features of independent claim 1.
  • the subclaims relate to particularly advantageous developments of the invention.
  • the invention relates to a filling element for filling bottles or similar containers with a liquid filling material, with a liquid channel formed in a housing of the filling element, the connection to be connected to a source for the liquid filling material and a dispensing opening for the Forms delivery of the liquid filling material to a container to be filled and has a liquid valve with a valve body interacting with a valve seat between the connection and the delivery opening.
  • the valve body can be moved by an actuating element at least between an open position and a closed position for opening and closing the liquid valve, specifically for controlling the filling process as a function of a flow meter.
  • the invention is distinguished in particular by the fact that the actuating element is designed as a pneumatic cylinder unit that is continuously adjustable between the open position and / or the closed position.
  • the filling element according to the invention thus simulates an inexpensive electric drive which not only serves to open and close the liquid valve, as is customary in the prior art for pneumatic drives, but can also stop or start in any intermediate position. In this way, the filling element according to the invention can also be easily adapted to different container sizes and container geometries.
  • the actuating element is designed as a double-acting pneumatic cylinder unit.
  • the double-acting pneumatic cylinder unit is arranged above the boiler and has at least one supply air connection and at least one exhaust air connection on a cylinder housing, via which a piston of the pneumatic cylinder unit that is vertically movable along the filling element axis can be acted upon with compressed air on both sides .
  • the piston is non-positively connected to a piston rod, which in turn acts in a non-positive manner on the actuating rod.
  • the piston rod is guided out of the cylinder housing on both sides by means of seals.
  • connection lines between the respective supply air connection or exhaust air connection and a compressed air generating device have a throttle check valve.
  • the respective throttle check valve each comprises a throttle device and a check valve.
  • the respective throttle of the corresponding throttle check valve is designed as an adjustable throttle.
  • At least one filling element has a sensor device on the side of the piston rod opposite the liquid valve, by means of which the relative positioning of the piston rod between its open position and closed position can be detected.
  • Container in the context of the invention is understood to mean any container, in particular bottles, cans, cups, etc., each made of metal, glass and / or plastic, preferably made of PET (polyethylene terephthalate).
  • the single figure shows a roughly schematic view of a preferred embodiment of the filling element according to the invention.
