Definitions

  • the invention relates to a device for pressing of pack coats, comprising: at least two movably mounted pressure strips for pressing the packing shells, and at least one drive for moving the pressure bars, wherein the pressure bars are mounted such that between the pressure bars a gap is formed, the longitudinal direction of the transport direction corresponds to the packing shells, and wherein the pressure bars are mounted such that the distance between the pressure bars is changeable.
  • the invention also relates to a method for pressing of pack coats.
  • Packaging can be done in different ways and in different ways
  • the cohesion between the compressed areas is achieved, for example, by providing an internal plastic layer, which becomes viscous when heated and thus in the subsequent
  • rollers can not compress the entire length of the package shell at the same time, but roll off in time on the packing jacket, the viscous plastic a
  • a disadvantage is the fact that in the device of EP 0 615 909 AI and WO 98/43876 AI no continuous, uninterrupted promotion of the packaging coats is possible. Instead, the packing shells must be stopped to be sealed by the tool. Only then can the promotion of packing coats be continued. It is therefore an intermittent mode of operation.
  • the cause of this restriction lies in particular due to the fact that it would be structurally very complex to carry the high-frequency vibrating sealing tools in sections with the conveyed packing shells and then return them again.
  • An intermittent mode of operation has the disadvantage that both the device and the packages and their contents are subject to heavy mechanical loading due to the constant accelerations. This can lead to a higher wear of the device as well as overflowing or intumescent packaging contents.
  • the production output of intermittent plants is often lower than the production output of continuously operating plants.
  • the invention is therefore based on the object of designing and further developing a device described in the introduction and explained in greater detail above in such a way that reliable compression of the packaging sheaths is achieved even with continuous delivery of the packaging sheaths.
  • a device according to the preamble of claim 1 characterized in that the pressure bars are mounted such that the pressure bars are movable in the longitudinal direction of the gap.
  • a device according to the invention for pressing - that is to say compressing - packing shells is initially distinguished by at least two movably mounted pressure strips for pressing the packing shells.
  • the pressure bars are preferably elongated, so that their extension in the longitudinal direction is greater than their extension in the transverse direction and / or in the vertical direction.
  • the extension of the pressure bars in the longitudinal direction is preferably greater than the length of the regions of the packing shells to be pressed, so that the entire seam can be grasped by the pressure bars in one step.
  • the pressure strips are preferably made of metal, in particular steel.
  • the device is characterized by at least one drive for moving the pressure bars.
  • the drive preferably comprises a motor, for example an electric motor, and - if necessary - elements for power transmission such Timing belts, shafts, joints, adapters and the like. It can be provided that each pressure bar is driven by one or more separate drives.
  • the pressure bars of the device are mounted such that between the pressure bars, a gap is formed, whose longitudinal direction corresponds to the transport direction of the packing shells. This arrangement of the pressure bars and alignment of the gap serves the purpose that the packing shells can be performed with their area to be pressed through the gap, without having to be stopped or deflected for the compression.
  • the pressure bars of the device are also mounted such that the distance between the pressure bars is changeable.

Abstract

L'invention concerne un dispositif (16, 16', 16") de pressage d'enveloppes d'emballage (10), comprenant au moins deux barres de pressage mobiles (29A, 29B) servant à presser les enveloppes d'emballage (10) et au moins un entraînement (24, 25, 38, 39) servant à déplacer les barres de pressage (29A, 29B), les barres de pressage (29A, 29B) étant positionnées de telle manière qu'entre les barres de pressage (29A, 29B) est produite une fente (S) dont la direction longitudinale (Xs) correspond à la direction de transport (T) des enveloppes d'emballage (10), et les barres de pressage (29A, 29B) étant positionnées de telle manière que la distance entre les barres de pressage (29A, 29B) peut être modifiée. L'invention vise à obtenir un pressage fiable d'enveloppes d'emballage, même en cas de transport en continu des enveloppes d'emballage. À cet effet, les barres de pressage 29A, 29B) peuvent être déplacées dans le sens de la longueur (Xs) de la fente (S). L'invention concerne également un procédé correspondant de pressage d'enveloppes d'emballage (10).
