Definitions

  • the invention relates to a method for filling and closing containers, preferably bottles with a liquid, in which containers filled in a filling device are closed with a closure element with deformation of the closure element and / or the container and with the formation of a sealing press fit between the closure element and the container and an apparatus for carrying out the method, the apparatus accordingly comprising a filling device for filling the containers and a closure device for closing the containers with a closure element.
  • Such methods and corresponding devices are used primarily in the beverage industry for filling and closing bottles, a so-called crown cap being used as the closing element.
  • a so-called crown cap being used as the closing element.
  • high demands must be placed on the tightness of the closure. Accordingly, a high sealing pressure is required between the crown cap and the bottle to be closed.
  • This high sealing pressure is achieved in that the crown cork is pressed against the opening edge of the bottle with a large force, for example 80 kp, and the crown edge of the crown cork is deformed in such a way that the crown cork is fixed to the bottle in the pressed position becomes.
  • the construction of the closure device must be designed so that correspondingly high contact pressures can be generated. This requirement results in restrictions with regard to the minimum achievable dimensions of the closure device and in particular the minimum achievable height.
  • the closing process within the closing device can therefore only take place relatively far away from the filling device due to its large dimensions, with the result that the filled bottles remain open for a relatively long period of time and the bottles contained therein Liquid is exposed to the ambient air.
  • This influence of the ambient air can significantly impair the long-term durability and the taste of a bottled beverage.
  • Closure devices of this type are described in the documents DE-AS 2042 328, DE-PS 23 13 268, DE-PS 22 53 985, US 3,759,012 and US 2,695,743.
  • a bottle breakage due to high closure pressures leads to considerable disruptions to the workflow.
  • the method according to the invention is characterized in that the closing element is attached in a first closing phase to form a light sealing press fit and in a second closing phase the final sealing press pressure is generated.
  • the closure device of the device according to the invention has a first device for attaching the closure element to the container to form a light sealing press fit and a second device for producing a sealing press fit with the final sealing press pressure.
  • the containers can be closed by the first device in such a way that the liquid contained therein is no longer exposed to the ambient atmosphere, while the containers are fed to the second device for final sealing.
  • the second device can thus be installed far away from the filling device, and there are no restrictions with regard to its size.
  • the first device intended only for stapling requires only a small size and can therefore advantageously be installed directly at the container outlet of the filling device.
  • the slight press fit generated in the first closing phase ensures that the carbon dioxide can escape from the bottles, whereby there is not the risk that the closing elements will be lifted from the container opening by the escaping carbon dioxide, as is the case only with the sealing caps in place and could fall down.
  • the closure element preferably a crown cap
  • the closure element can be suitably preformed by a snap or clamp fit in order to produce the light sealing press fit in the first closing phase.
  • the filling device is designed as a carousel filling device
  • the first device for the first Sealing phase has a stapling device which engages in the base circle of the carousel filling device at the container outlet with holders for the closure elements.
  • the stapling is carried out in such a way that the containers arranged in the carousel filling device on lifting tables under filling valves, which can be pressed against the filling valves by the lifting tables, are pressed from below with the aid of the lifting tables against the closure elements held in the holders of the stapling device, the containers Compared to the filling valves have been lowered so far that the stapling device can engage in the space between the container and the filling valve.
  • the containers with the attached closure element are transferred at the outlet of the filling device to a transport device designed as a turntable, through which the containers can be fed on a transport circular path to the second device, which is arranged away from the filling device, for the final sealing of the containers.
  • the stitching head has at least three pin elements which are shaped at their end facing the crown cork edge to form a seat which aligns the crown cork with a seat cross-section tapering in accordance with the shape of the crown cork edge.
  • This configuration ensures that the Crown cap is held on the stitching head in a defined position, so that when the stitching head and the container to be closed are brought into the closing position, an exact alignment between the crown cap and the container is ensured.
  • precise alignment of the crown caps on the stitching head is very difficult.
  • the crown cap does not have to lie directly on the magnetic holder.
  • the magnetic holder can instead be set back from the seating position of the crown cap.
  • a deformation of the crown cork rim which is particularly suitable for stapling the crown cork is achieved by providing in a further advantageous embodiment of the invention that the pins are undercut in their part adjoining the cone end and in particular taper conically.
  • a guide track can be provided under the rotating stitching heads for feeding the crown caps to the stitching heads.
  • Crown caps introduced from a storage container into this guideway can either be moved by a movable cap crown towards the lowering stitching head or the crown corks are fed to a stitching head which has a deformation pin with an extension which serves as a driver for the crown cork in the guideway.
  • the cap pushes the crown cap onto an inclined ramp and raises it into the effective range of the magnetic holder.
  • the device comprises a pneumatic drive device for the stitching head.
  • the drive device comprises at least one pressure cylinder with a piston guided therein.
  • Circumferential stitching heads are preferably provided in the manner of a carousel, to which a pressure cylinder with a piston is assigned, and which can be moved to attach the crown corks into the bottle conveyor track of the filling device, preferably a carousel filling device, so that they cut or tangle the conveyor track.
  • the stitching heads need only be aligned with the bottle mouths over a very short path section, and no reduction in the bottle conveying speed is required to carry out the stitching process.
  • the printing cylinders associated with the rotating stitching heads are connected to one Pressurized gas source connectable passage channels for the control disk having pressurized gas connected to the cylinder interior, the passageways to the pressurized gas source via a slide shoe with a pressurized gas supply channel opening towards a seal sliding surface, the opening end of which can be covered by the control disk under abutment against the seal sliding surface and with opening ends facing away from the pressure cylinders Passage channels can be connected, can be connected.
  • cross-sectional areas of each passage channel and the cross-sectional area of the compressed gas supply channel are advantageously dimensioned at least at their mutually connectable opening ends in accordance with a desired chronological sequence of the attachment process.
  • the cross section of the compressed gas supply channel is expediently smaller than the cross section of the passage channel, at least at the mouth opening facing the control disk. Given given dimensions of the sliding block, the sealing of the compressed gas supply channel against the control disk, if no connection to a through channel is established, is facilitated in that the sealing sliding surface is large against the opening of the compressed gas supply channel in the sliding block.
  • the sliding block is connected to a piston guided in a pressure cylinder, the end of the compressed gas supply channel facing away from the control disk ending in the cylinder interior.

Abstract

Selon un procédé amélioré de remplissage et de fermeture de récipients, notamment de remplissage de bouteilles avec un liquide, des récipients remplis dans un dispositif de remplissage sont fermés avec un élément de fermeture, l'élément de fermeture et/ou le récipient étant déformé, pour créer un contact étanche entre le récipient et l'élément de fermeture. Le procédé se caractérise par le fait que l'élément de fermeture est fixé, pendant une première phase de fermeture, avec une pression d'étanchéité, afin de créer un contact étanche, puis est soumis, pendant une deuxième phase de fermeture, à la pression définitive d'étanchéité. L'invention concerne également un dispositif de mise en oeuvre du procédé.
