  • the present invention is based on the object
  • the transport device is designed in such a way that they do not allow contamination to be introduced into aseptic areas of the device.
  • the transport device comprises a non-circulating transport device, which extends over the entire length of the device, for linear, clocked transport of the open pack casings, pack bodies that are closed at the bottom, and finished packs that, in order to Transport device around, a sterile air chamber is formed in which the sterilization unit, device for bottom sealing, filling unit and device for gable sealing are arranged and that the sterile air chamber can be continuously supplied with sterile air.
  • the non-circulating transport device is preferred as a horizontally running one
  • EP 3 072 834 A1 shows a transport device with a transport rake and a counter rake as well as a method for operating such a transport device for transport goods.
  • the encapsulation of the walking mechanism by means of a sterile air chamber defines an aseptic area that does not require air ducts for a laminar flow through perforated plates or the like and is therefore far "tidier", so that larger and moving parts such as For example, ultrasonic sealing tools can be arranged inside the sterile air chamber.
  • the task is solved in that the packaging casings are transported through a sterile air chamber from the infeed of the packaging casings to the discharge of the finished packs in a linear direction by means of a non-circulating transport device, which is preferably designed as a horizontal walking mechanism.
  • a further embodiment of the invention provides that the walking mechanism has at least two transport rakes arranged in parallel in a horizontal plane, each with a plurality of tines pointing towards one another, and that the

  • the use of such a walking mechanism leads to a significantly smaller moving mass of the transport device.
  • a further teaching of the invention provides that the opposing transport rakes of the walking mechanism are arranged in several different levels. In contrast to the cell chains described above, the height of the packaging shells, packaging bodies that are already closed at the bottom or the completely filled packaging can be shifted between the individual levels during passage through the device.
  • Walking work have transfer elements for vertical movement between the different levels of walking work.
  • the opposite transport rakes produce receiving profiles designed differently over their length for receiving the pack casings, pack bodies and packs have packs. This applies on the one hand to the design of the receiving profiles and on the other hand also to the height ranges of the engagement of the individual receiving profiles, so that an optimal engagement can always take place by jamming the transport rakes with the pack bodies or packs according to their respective status and production step.
  • Another preferred teaching of the invention provides that the opposite transport rakes are designed as mobile and static walking bars and that at least the mobile walking bars are designed as actively cooled bars.
  • the transport rakes of the walking mechanism no longer leave the sterile air chamber, they are significantly heated up by the hot sterile air that is constantly being refilled, which leads to thermal distortion or unwanted changes in length of the transport rakes. Active cooling can reliably prevent this.

  • the use of a single, common sterile air chamber leads to a simplified structure and also enables automatic cleaning, which was previously not readily possible with known multi-lane filling machines.
  • a further preferred teaching of the invention provides that the sterilization unit from the sterile agent nozzle, the device for bottom sealing, the filling unit and the device for gable sealing form a common aseptic area. Due to the fact that the sterile air chamber, especially in the aseptic area, is constantly supplied with sterile air, it is ensured that no air can enter the sterile air chamber or inside the sterile air chamber from the outside due to the slight overpressure that occurs

  • the drive of the walking mechanism is arranged outside the sterile air chamber.

  • Another preferred embodiment of the method according to the invention provides that the sterile air chamber is encapsulated around the walking mechanism and that within the sterile air chamber there is a continuous supply of sterile air. It is also possible to preheat and, if necessary, dedust the packaging jackets before sterilizing them. The actual sterilization of the packaging jackets is then carried out by spraying a sterilizing agent such as H 2 O 2 into the aseptic area of the sterile air chamber, with the inner and outer surfaces of the packaging jackets and the pouring elements on them being completely sterilized. After sterilization, the sterilized packaging jackets are preferably dried.

Abstract

L'invention concerne un appareil et un procédé de fabrication d'emballages composites carton/plastique remplis, ledit appareil comprenant : un dispositif de transport ; un dispositif (15) pour l'alimentation de manchons d'emballage pliés à plat (10, 10') dans l'appareil ; un dispositif pour déplier les manchons d'emballage ; une unité d'application (16) pour l'application d'un élément d'ouverture et de coulée (F) ; un dispositif de pré-pliage des manchons d'emballage ; une unité de stérilisation (17) ; un dispositif (21) pour plier et sceller les surfaces inférieures (8) des manchons d'emballage (10, 10') ; une unité de remplissage (22) ; un dispositif (23) pour plier et sceller les surfaces de pignon (9) ; et un dispositif pour décharger les emballages remplis (P). Afin de concevoir le dispositif de transport d'une manière qui empêche la contamination de zones aseptiques de l'appareil, l'invention prévoit que le dispositif de transport comprenne un dispositif de transport non circulant qui s'étend sur toute la longueur de l'appareil pour le transport linéaire cadencé des manchons d'emballage ouverts (10), des corps d'emballage scellés par le fond et des emballages finis (P) ; pour une chambre à air stérile (25) destinée à être formée autour du dispositif de transport, dans lequel l'unité de stérilisation (17), le dispositif (21) pour sceller le fond, l'unité de remplissage (22) et le dispositif (23) pour sceller le pignon sont situés ; et pour la chambre à air stérile (25) d'être alimentée en continu avec de l'air stérile.
