Definitions

  • the invention relates to a method for packaging palletized stacks of goods with a heat shrink film, in which the stack of goods is initially exposed on its underside, in particular raised and wrapped with the heat shrink film in such a way that its lower edge projects downward over the stack of goods and this edge by means of a blower is sucked under the stack of goods before the heat shrink film is heated to its shrink temperature.
  • the invention further relates to a device for carrying out this method with a hood pulling station, a lifting platform arranged below the hood pulling station and a suction fan also provided there, and a shrinking device for heating the shrink film to shrink temperature.
  • the device essentially consists of a hood pulling station and a shrinking station, both stations being connected by a chain conveyor.
  • a lifting platform and a suction fan are located below the hood pull-over station.
  • the stack of goods can be raised so far that the edge of the shrink film drawn over the stack of goods can be gripped by the suction fan and drawn under the stack of goods.
  • the fact that the edge of the shrink film protrudes below is additionally supported by appropriate tools that bend the edge under the stack of goods.
  • the stack of goods is then lowered onto the chain conveyor track, the folded edge being pressed by the chains against the underside of the stack of goods.
  • the stack of goods is then transported to the shrinking station, where hot gas is applied to the shrink film, which can be done, for example, by a hot gas mast guided around the stack of goods or by a vertically movable ring burner.
  • the invention is therefore based on the object of further developing the method mentioned in such a way that the shrinking result at the lower edge of the shrink film is significantly improved and the device can also be made considerably simpler and more space-saving.
  • This object is achieved in that the lower edge of the shrink film is heated to the shrink temperature in the free state of the stack of goods and the edge still at shrink temperature - or only slightly below - is pressed against the underside of the stack of goods.
  • the lower edge of the shrink film is first heated according to the invention and only then is it beaten under the stack of goods.
  • This has the advantage that hot gas is applied to the entire surface of the lower edge of the shrink film and brought to the shrink temperature.
  • the surfaces of the edge that come to lie on one another then glue, as a result of which the shrink film in this area is given a very good hold for the subsequent shrinking of the side surfaces.
  • the lower edge of the shrink film can then hardly be pulled up by the further shrinking process.
  • the hood pulling station can be combined with the shrinking station in this process.
  • the space requirement and the design effort for the conveyor track are correspondingly less.
  • Pressing the lower edge of the shrink film against the underside of the stack of goods after heating the shrink film can be done, for example, using appropriate tools. However, it is structurally simpler to simply place the stack of goods, which has initially been lifted, with the edge of the shrink film still at the shrink temperature on a support which will generally be the conveyor track itself.
  • the invention Method of arranging the shrinking device at the hood pulling station, that is to say combining the two stations with one another. It is particularly expedient if the lifting platform for lifting the stack of goods has lifting rams which can be moved into the openings on the underside of the stack of goods to the underside of the surface of the stack of goods. The lifting stamps then no longer hinder the shrinking of the lower edge of the shrink film.
  • the device according to the invention is illustrated in more detail using an exemplary embodiment. It shows a shrinking station 1, which consists of a mast bridge 2 and a ring burner 3.
  • the mast bridge 2 has two masts 4 arranged side by side in a plane perpendicular to the plane of the drawing, of which only the front one in this view can be seen here. Both masts 4 are connected to one another via a transverse yoke 5 connecting their upper ends.
  • a drive 6 is guided vertically displaceably on each mast 4, the guidance taking place via rollers 7, 8 .
  • the vertical movement of the carriage 6 is effected via a circulating chain 9, the deflection at the lower and upper ends of the mast 4 taking place via corresponding chain wheels 10, 11.
  • a corresponding drive is also arranged on the mast, which is not visible here, the two drives 6 being synchronized with one another in such a way that they are always at the same height.
  • the drives 6 are connected to one another by the ring burner 3, which has a rectangular, frame-like shape, the one of which enclosed area is large enough so that the ring burner 3 can be moved vertically over a stack of goods.
  • Such a stack of goods 12 is located below the ring burner 3 on a roller conveyor 13.
  • the stack of goods 12 consists of a conventional pallet 14 and the goods 15 stacked thereon.
  • a lifting platform or lifting device 16 which is shown here schematically as a scissor lift.
  • lifting rams 17, 18 project upwards through corresponding gaps in the roller conveyor path 13 between the base strips 19 of the pallet 14.
  • a schematically illustrated suction fan 20 is also arranged.
  • the method according to the invention proceeds with this device as follows.
  • the ring burner 3 is lowered to the level of the roller conveyor path 13 by a corresponding movement of the drives 6. Then the stack of goods 12 is raised by lifting the lifting rams 17, 18 by means of the lifting device 16 by approximately the height of the pallet 14, for example by approximately 15 cm. Then the shrink film is pulled down with a known hood covering device, not shown here, from above over the stack of goods 12 so far that the lower edge of the shrink film projects downwards over the underside of the stack of goods 12 or the pallet 14. The hood pulling machine is then moved back again.
  • the lower edge of the shrink film is subjected to hot gas through the ring burner 3, so that it heats up to its shrinking temperature and contracts under the underside of the pallet 14. This is supported by the suction fan 18.
  • the stack of goods 12 is then lowered again onto the roller conveyor 13 while the edge of the shrink film is still heated, as a result of which the hot edge between the rollers of the roller conveyor 13 and the underside of the pallet 14 is pressed together with the effect that the individual layers of this edge are welded together. This gives the lower edge of the shrink film an extremely good hold.
  • the vertical movement of the ring burner 3 then begins.
  • the shrink film contracts strongly over the side surfaces.
  • the ring burner 3 is stopped in order to cause shrinkage on the top of the stack of goods 12.
  • the stack of goods 12 can then be moved out of the shrinking station 1 via the roller conveyor track 13. The procedure described above is then repeated for a new stack of goods.
