  • the present invention relates to the field of packaging machines. More specifically, the present invention relates to the field of machines for packaging flexible material packages. More specifically, the present invention relates to an assembly for opening packages that can be added, for example, to an existing packaging machine in order to supply suitably opened packages to the filling station of the packaging machine itself.
  • Such flexible material packages comprise two parallel side walls, two side gussets and a bottom surface.
  • the side walls, the gussets and the bottom surface form the containment volume and the filling mouth of the package, with the filling mouth being opposite the bottom surface.
  • Examples of such packages and methods for producing them can be found in European patent applications EP 3 395 709 A1 , EP 3 790 809 A1 , and EP 3 790 733 A1 .
  • the package to be filled is made of a particularly rigid material, for example due to the nature of the material itself and/or its thickness, and the product to be placed in the package is, on the other hand, light, such as powdered coffee or cocoa, it may be difficult to fill the package properly if it is not opened properly beforehand, due to possible folding of the side gussets and/or the bottom of the package.
  • the product to be inserted into the package may not be able to completely flatten the bottom of the package and/or its side gussets, thereby failing to open it completely.
  • the bottom of the package and/or the side gussets may therefore remain partially folded, which can result in insufficient filling of the package and a failure to fully utilize its capacity.
  • properly opening the package before filling is also preferable for aesthetic reasons and to facilitate the closing and/or storage operations of the filled packages.
  • the present invention is based on the idea of operating both on the side walls and on the bottom of the packages to be filled in order to open them adequately so that their entire capacity can be used for their filling.

  • the movement of the spreading elements controlled by the second driving means allows, for example, the parallel side walls of the package to be moved apart from each other, at least partially, so as to unfold at least partially and/or completely the side gussets and/or the bottom surface of the package.
  • the third driving means are suitable for further moving the pressing element along the first direction, independently of the spreading elements.
  • the third driving means allow the pressing element to be moved along the first direction within the package to be opened independently of the spreading elements. Both the pressing element and the spreading elements can therefore be found within the package to be opened, and the third driving means allow the pressing element to be moved further along the first direction while keeping it within the package and without moving the spreading elements along the same direction.
  • the movement of the pressing element along the first direction controlled by the third driving means advantageously allows the bottom surface of the package to be pushed so as to flatten it.

Abstract

L'invention concerne un ensemble (1) pour ouvrir des emballages (C) à remplir avec un produit (P), par exemple du café, comprenant : des éléments d'écartement (6, 7) et un élément de pression (8); des premiers moyens d'entraînement (13) aptes à déplacer les éléments d'écartement (6, 7) et l'élément de pression (8) conjointement le long d'une première direction (Z); des deuxièmes moyens d'entraînement (14) aptes à écarter et fermer les éléments d'écartement (6, 7); des troisièmes moyens d'entraînement (15) aptes à déplacer davantage l'élément de pression (8) le long de la première direction (Z) indépendamment des éléments d'écartement (6, 7). De plus, l'invention concerne une machine d'emballage, un procédé d'ouverture d'emballages, un procédé de remplissage d'emballages et un procédé de réhabilitation d'une machine d'emballage.
