Definitions

  • the invention concerns an exchange method for a supply of tube foil that has been pressed together in a zigzag shape for a packaging machine for powdery- or granular materials.
  • Packaging machines of this kind are disclosed in EP 0.443.349. They make use of tube foil as packaging material and experience the problem that regularly a new supply of tube foil has to be attached to the head. For some of the materials that are to be packed, it is of vital importance that they are not put into contact with the open air. If such is the case, the pack is filled with nitrogen.
  • the filling head When installing the new supply of tube foil to the upper side of the head of the filling tube in the conventional way, the filling head is brought into contact with the open air and powder can be dispersed into the air, by which the filling unit is contaminated or residue of the material to be processed can spread in the surroundings or fall on to the floor/ground and polluting it.
  • the invention prevents these problems by making use of an exchangeable carrier with a supply of tube foil which is applied to the filling head.
  • This exchange method comprises that the first part of the new tube foil is used for dust proof wrapping of the last part of the preceding tube foil with a new elastic ring.
  • Fig. 1 shows a filling head, generally indicated with 20,of a packaging machine according to EP 0.443.349, which is provided with several devices to package powdery or granular products P, such as synthetic granules, in tube foil.
  • a support ring (2) is dust proof and gas tight connected with the filling head (20). Below the support ring (2) an inflatable rubber ring band (3) is allocated that acts as temporary sealant in the packaging cycle.
  • the tube foil (4) which is pulled off the carrier, is sealed or tied up at (5), to form a bottom of a bag.
  • Fig. 2 shows the starting position in which a carrier (1) with the supply of tube foil (4) is placed on the filling head.
  • the tube foil is placed on the carrier in such a manner that the end part (6) is back folded under or zig-zag part so that the first (begin) part (7) extends at the same side over the last part (6).
  • the end part is clamped dust proof on the support ring (2) with an elastic ring (8).
  • This ring may have a round, oval or rectangular cross section.
  • Fig. 3 shows that the begin part (7) is pulled down and is sealed at (5) with a welding or tie up.
  • the bag that is formed this way is filled thereafter with product P and sealed whereby a second sealing at the top forms the bottom of the next bag.
  • the tube foil of the carrier (1) is used as follows:
  • the foil of the new carrier (1') can now further be used for a new set of packaging.
  • the exchangeable carrier (1) preferably is manufactured from cardboard or synthetic material that can be recycled. These carriers can separately be loaded with the synthetic tube foil and ready to use delivered to the user for use on his packaging machine.
  • Fig 6 shows a cylindrical carrier in a schematic axial cross section. It has a number of reinforced support rings (11, 12, 13) of flanges, by which the stiffness is enlarged.
  • the upper flange 11 has a larger outer diameter than lower flanges 12 and 13.
  • the carrier is installed in the packaging machine with the help of a second inflatable rubber ring band or a other type of quick acting closure, such as De-sta-co clips of the 205USS type of a clip binding.
  • the last piece of tube foil that was closed during the last filling, together with the elastic ring that has been used, is wrapped in the first pack from the new supply of tube foil and can be removed without the filling head being exposed to the outside air.
