Definitions

  • the present invention relates to a filling system for filling a filling product into a container to be filled and for subsequently sealing the filled container with a container closure.
  • containers to be filled are fed to a filler, in which the containers are filled with the corresponding filling product, ie the beverage.
  • the filled containers are then ejected from the filler and fed to a capper, in which the filled containers are sealed with a container cap.
  • fillers and cappers each of which is designed as a rotary design. They therefore each comprise a carousel rotating about a horizontally oriented central axis of rotation, on the circumference of which a large number of treatment devices and container holders or container receptacles assigned to them are arranged. At least one transport star wheel is provided between the filler and the capper to transfer the containers.
  • the transport stars arranged before, between and after the filler and the capper, as well as the carousels of the filler and the capper are designed with ever larger diameters, which leads to ever larger and more expensive structures and accordingly higher costs for the production and during the operation of the bottling plants. Due to the ever-growing carousels, more and more accurate or more precise machines are required in order to be able to adequately treat the containers, especially in the case of containers without carrying rings, and to be able to convey them through the filling plant.

  • the closure devices 210 then also have this orientation, which deviates from the parallel orientation to the axis of rotation 202 of the closure device 200 .
  • the guide 234 can also be arranged in the area of the upper side of the sealer 200 and hung down to the container receptacle 230 instead of being arranged in a lower area of the upper part of the sealer 200 .
  • the leadership can be 234 be arranged radially inside the guide 215 and preferably be connected to the container receptacle 230 via a linkage.

  • the containers 400 can be transferred flatly with their bottom 404 onto the linear outfeed belt 120 without an unstable transfer and conveyance of the containers 400 occurring due to an abrupt change in inclination of the containers 400 occurring during the transfer.
  • the container receptacles 230 in the transfer section 206 can be pivoted radially inwards out of the horizontal orientation assumed for the transfer to the conveyor belt 120 when the container 400 being held is transferred to the outfeed conveyor 120 as soon as the bottom 404 of the container 400 to be transferred comes into contact with the conveyor belt 120 has come, for example in the in figure 2 orientation shown on the left on the capper 200 perpendicular to the axis of rotation 202 of the capper 200 in order to facilitate release of the held container 400 to the outfeed belt 120.
  • any spike plate provided on the container receptacle 230 can be disengaged from the container 400 placed on the conveyor belt 120 or from a carrying ring of the container 400 (not shown here).

  • the axis of rotation 306 of the filler 300 can also be designed to be inclined relative to the vertical. This may be advantageous with regard to an improved transfer of filled containers 400 to the sealer 200.
  • the inclined position of the axis of rotation 306 with respect to the vertical can be realized by a mechanism corresponding to that of the capper 200, for example comprising a correspondingly designed pivot bearing.
  • the oblique position of the closer 200 with respect to its axis of rotation 202 and/or the oblique position of the filler 300 with respect to its axis of rotation 306 can alternatively be realized by arranging feet of different lengths on the closer 200 or filler 300.

  • the longitudinal axis 405 of the container 400 thus encloses an angle with the vertical which corresponds to the sum of the angle of inclination ⁇ and the angle of deflection ⁇ .
  • This embodiment can be particularly advantageous when the diameters of the pitch circles 208, 307 differ greatly and/or at a particularly high conveying speed.
  • the additional deflection of the container 400 during the transfer can be used to prevent the filling product and/or nitrogen above it from spilling out of the container 400 at high conveying speeds due to a change in centrifugal force acting on the liquid filling product in the container 400.
