  • the present invention relates to a device for cleaning a piece of packaging material.
  • Tetra Brik Aseptic registered trademark
  • a typical example of this type of package is the parallelepiped-shaped package for liquid or pourable food products known as Tetra Brik Aseptic (registered trademark), which is made by folding and sealing laminated strip packaging material.
  • the packaging material has a multilayer structure substantially comprising a base layer for stiffness and strength, which may comprise a layer of fibrous material, e.g. paper, or of mineral-filled polypropylene material; and a number of layers of heat-seal plastic material, e.g. polyethylene film, covering both sides of the base layer.
  • a base layer for stiffness and strength may comprise a layer of fibrous material, e.g. paper, or of mineral-filled polypropylene material; and a number of layers of heat-seal plastic material, e.g. polyethylene film, covering both sides of the base layer.
  • the packaging material also comprises a layer of gas- and light-barrier material, e.g. aluminium foil or ethyl vinyl alcohol (EVOH), which is superimposed on a layer of heat-seal plastic material, and is in turn covered with another layer of heat-seal plastic material forming the inner face of the package eventually contacting the food product.
  • gas- and light-barrier material e.g. aluminium foil or ethyl vinyl alcohol (EVOH)
  • EVOH ethyl vinyl alcohol
  • packages of this sort are produced on fully automatic packaging units having a supply station fed with reels of a web of packaging material.
  • the web of packaging material is cut in a paper factory, at a first lateral edge and a second lateral edge, which are opposite to each other.
  • the supply station comprises a pair of first wheels defining relative grooves engaged by the first lateral edge, and a pair of second wheels cooperating with relative opposite sides of the web in a position close to the second lateral edge.
  • the first wheels and second wheels are effective in guiding the web of packaging material, as the latter advances.
  • a photocell is mounted inside the supply station, with the aim of detecting the passage of a plurality of markers carried by the web and associated to the position of relative packages to be formed.
  • the real speed of the web is detected.
  • the real speed of the web is compared with the nominal speed and the web is accordingly accelerated or decelerated.
  • a continuous tube is formed from the web-fed packaging material in the packaging unit; the web of packaging material is sterilized in a sterilizing unit, e.g. by moving the web inside a dip of a chemical sterilizing agent such as a hydrogen peroxide solution, which is subsequently removed, e.g. by heating and evaporation, from the surfaces of the packaging material.
  • a chemical sterilizing agent such as a hydrogen peroxide solution
  • the sterilized web is maintained in a closed, sterile environment, and is folded into a cylinder and sealed longitudinally to form a tube.
  • the tube is fed in a first vertical direction parallel to its axis, is filled continuously with the sterilized or sterile-processed food product and is heat-sealed at equally spaced cross sections by two pairs of jaws to form pillow packs each having a top and a bottom transverse sealing band, i.e. a band extending along a second direction orthogonal to the first direction.
  • Pillow packs are separated by cutting respective sealing bands and are then fed to a folding station, in which they are fold so as to form respective packages.
  • the packaging material may be cut in blanks, which are folded on forming spindles to form the packages, which are then filled with the food product and sealed.
  • An example of this package is the "gable-top" package commonly known by the trade name of Tetra Rex (registered trademark).
  • waste particles such as polyethylene fibres and/or dust and/or carton fibres, may form on the first and second edge of the packaging material.
  • these deposits may cause the malfunctioning of the stations downstream from the supply station, for example they may cause the gripping of the bearings of the stations downstream from the supply station, so increasing the maintenance cost of the packaging machine.
  • the deposits may reduce the effectiveness of the sterilizing unit, thus rendering necessary a periodical cleaning action of the dip.
  • the sterilizing unit may also comprise, instead of a dip of a sterilizing agent, a radiation emitting device, which emits a radiation against the web.
  • the residues can in no way be removed by the sterilizing unit and can, therefore, reach the stations where the tube is formed and filled with the pourable food product.
  • a need is therefore especially felt within the industry to prevent the residues from reaching the stations where the tube is formed and filled with the pourable food product.
