Definitions

  • the present invention relates to an apparatus and a method for transforming plastic preforms to plastic containers.
  • Such devices and methods have been known for a long time from the prior art.
  • the plastic preforms are usually heated within a heating device to a temperature necessary for the blow molding process and then fed to a blow molding machine.
  • the plastic preforms are usually reshaped within a blowing station by applying a flowable medium and in particular compressed air and by simultaneous or previous stretching with a stretching rod to plastic containers and in particular plastic bottles
  • the plastic preforms have also been filled simultaneously during the forming, with the plastic preforms being expanded with a liquid medium and, in particular, already with the liquid filling medium.
  • the preforms heated by an oven are transferred by means of a transport device and in particular a transfer star into the forming station or blowing station and then charged with the liquid medium.
  • a transport device and in particular a transfer star into the forming station or blowing station and then charged with the liquid medium.
  • the bottles are completely formed during filling and forming (LiquiForm process) when leaving the process machine and are also filled, but not yet closed. Due to the jerky transfers and the accelerations acting on the container during transport out of the mold, it is increasingly the case that the containers splash over.
  • the present invention is directed to a device for converting plastic preforms to plastic containers with a first transport device, which transports the plastic preforms along a predetermined transport path, with a blow molding machine which is arranged along the transport path and which has at least one conversion station , within which the plastic preforms can be deformed by applying a liquid medium to the plastic containers and can be filled at the same time and with a feed device, via which the plastic preforms can be fed to the blow molding machine.
  • the device has a second transport device, by means of which sealing devices for at least sections and temporary sealing an opening region of the plastic preforms and / or the plastic containers along a predetermined transport path transportable and the feeder can be fed, wherein the plastic preforms and the sealing means are jointly supplied to the blow molding machine ,
  • the sealing devices are preferably applied to these and in particular to an opening region of the preforms prior to filling and forming the preforms.

  • the device according to the invention and also the method according to the invention accordingly have the particular advantages that, due to the sealing contact between the sealing device and the mouthpiece of the container during container removal, overflow of the filling medium during container removal can be prevented, whereby the shape remains dry and as a result, the process reliability can be increased and the reject rate can be reduced.
  • cycle machines there is the advantage of greater accelerations without spilling the container, whereby the cycle times can be reduced and the output of the system can be increased.

  • the stretch rods preferably have an electric drive. However, it is also possible to control the stretching bars via curves.

  • these blow mold halves are detachably arranged on a mold carrier shell or on the blow mold carriers.
  • the blow mold carriers are pivotable relative to each other to open and close the blow molds.
  • the blow mold carrier has locking mechanisms in order to lock the mold halves to one another during the blowing process.
  • the blow molding machine or the carrier and the blow mold arrangements are arranged within a clean room which delimits the blow molding machine from an unsterile environment.
  • Drive devices for the closure, locking and / or opening of the blow molds are preferably arranged outside the clean room.

In any case, however, the sealing devices are applied to the preforms before they are filled with a liquid.
  • the device has a discharge device, via which the formed and filled plastic containers and the sealing processing facilities are jointly discharged from the blow molding machine.
  • the sealing devices and the plastic containers are fed together to the blow molding machine and also removed together again from this.

  • a sterilization device for sterilizing the sealing devices can also be arranged at the inlet of the second transport device.
  • a discharge path for discharging defective containers and / or sealing devices can be provided on the feed device and / or discharge device and / or the second transport device.

  • the inspection device arranged on the feed device inspects the arriving preforms and accordingly discharges them via the discharge path arranged on the feed device. Subsequently, the inspection device arranged on the discharge device inspects the finished containers and, if necessary, forwards them via the discharge path arranged on the discharge device and the inspection device arranged on the second transport device accordingly inspects the sealing devices and directs faulty seals over the on the second transport device arranged Ausleitpfad. In addition, it would preferably also be conceivable to detect, for example, burst containers by a pressure detection and in particular a pressure curve during molding.
  • the sealing devices can be removed from the plastic containers immediately before the plastic containers are closed.
  • the sealing devices are therefore preferably arranged only temporarily on the Mün- dungs Scheme of the containers.
  • the term immediately before closing is understood to mean that there is only a very short transport path between the removal of the seals and the application of the closures.
  • the peripheral speed after the blow molding machine, i. in the discharge device lower, so that the risk of overspill is lower.
  • the level of the possibly foamed medium within the container has already dropped again at this time.
  • the closure is a sleeve which extends the mouth region of the plastic containers in a longitudinal direction of the plastic containers. Accordingly, the opening area is geometrically extended by the sealing device in order to prevent the medium from sloshing out of the container.
  • the sealing device preferably has a continuous opening which lies essentially over the mouth of the container. Particularly preferably, the container can also be deformed and filled through this opening.
  • the diameter of the opening advantageously corresponds to the diameter of the mouth opening of the container. Excess gaseous medium can also escape from the container through this opening after filling, which, in contrast to a completely sealed seal, also reduces the risk of foaming of the filling medium in the container, since the gaseous medium does not escape in a closed seal could.
  • Such an opening in the sealing device is therefore particularly advantageous in the case of carbonated beverages in the container.
  • it is a non-carbonated beverage, it would also be conceivable to use a closed sealing device, since the risk of foaming is considerably lower here.

  • the sealing device consists of a heat-dissipating material or the sealing device is a steel part with a sealing insert.
  • a height of the sealing device in the longitudinal direction of the plastic containers is at least twice the mouthpiece height. The extension sleeve or the sealing device therefore extends the mouth region of the container at least twice the mouthpiece height.

Abstract

L'invention concerne un dispositif (1) pour le formage de préformes en plastique (10) en récipients en plastique (20), comprenant un premier système de transport (2) qui transporte les préformes en plastique (10) le long d'une trajectoire de transport (T1) prédéfinie ; une machine de moulage par soufflage (5) qui est disposée le long de la trajectoire de transport (T1) et qui présente au moins une station de formage (4) à l'intérieur de laquelle les préformes en plastique (10) peuvent être mises sous forme de récipients en plastique (20) par application d'une substance fluide et peuvent dans le même temps être remplies ; et un système d'amenée (3) permettant d'amener les préformes en plastique (10) à la machine de moulage par soufflage (5). Selon l'invention, le dispositif (1) présente un second système de transport (7) permettant le transport de systèmes d'étanchéification (8) destinés à assurer l'étanchéité au moins par zones et temporairement d'une zone d'embouchure (10a) des préformes en plastique (10) et/ou des récipients en plastique (20), le long d'une trajectoire de transport (T2), et permettant leur transfert au système d'amenée (3), les préformes en plastique (10) et les systèmes d'étanchéification (8) pouvant être amenés conjointement à la machine de moulage par soufflage (5).
