Definitions

  • the invention relates to a method for packaging a stack of goods arranged on a pallet, in particular from bottles, cans or the like, wherein a shrink hood pulled over the stack of goods progressively shrinks in the vertical direction and with one arranged between the stack of goods and the pallet, over the edge of the pallet protruding film is welded.
  • the invention also relates to an apparatus for performing the method.
  • the air then remaining in the shrink hood can no longer escape and is also heated during the subsequent shrinking of the shrink hood.
  • the air expands and there is a so-called balloon formation, which under certain circumstances expands the shrink hood so much that it does not shrink back completely even after the air has cooled. For this reason, partial vacuum is already generated in the shrink hood during the formation of the shrink hood, which draws the shrink hood onto the stack of goods.
  • a disadvantage of this is that the shrink hood, which is generally drawn with oversize over the stack of goods, folds around the stack of goods and around the pallet, thereby at least partially restricting the heating of the shrink hood material, on the one hand because of the multiple layers in the area of the folds and on the other hand because of the Contact with surface areas of the stack of goods.
  • the shrink hood forms thin spots next to the folds because the heat stays in the folds longer and the shrink hood with its high cold shrink force pulls film material next to the folds, where the heat has unimpeded access.
  • the folds thus formed usually run downward at an angle near the four vertical edges of the stack of goods and form what is known as rain gutters in which water that runs down during outdoor storage looks for a way and, if necessary, also penetrates through small holes in the fold area to the stack of goods.
  • the object of the invention is to tightly pack a stack of goods, in particular as hygienic packaging.
  • a device for performing the method has a parking space or a conveyor for the stack of goods, a device for covering the stack of goods with a shrink hood, which is gripped at its lower edge by grippers, a shrinking device which can be moved up and down in the vertical direction and a below the parking space or fan arranged on the conveyor.
  • the device is characterized in that at least one movable foil deflector is provided on the parking space or conveyor outside the space occupied by the pallet, but within the working area of the grippers.
  • Foil deflectors are preferably arranged on opposite sides of the conveyor, in particular in such a way that the foil deflectors are located in the region of the end faces of the pallet, because the lengths are the same on standard pallets and only the widths are different.
  • the one or more foil deflectors are extended so that they protrude into the area of the stack of goods.
  • the shrink hood is then pulled over the stack of goods, the grippers holding the lower edge of the shrink hood moving outside the film deflectors. After the grippers have released the lower edge of the shrink hood and moved back to their starting position, the shrinking process can begin, the lower part of the shrink hood being kept away from the stack of goods, the pallet and the film lying on the pallet at least in regions.
  • the film deflectors When the shrinkage reaches the area of the film deflectors, they are removed, for which purpose the film deflectors are preferably pivotably mounted about a horizontal axis and have a swivel drive. The shrinkage then continues to the lower edge of the shrink hood, including a weld with the foil on the pallet.
  • the foil deflectors can be fork-shaped and accordingly have fork tines.
  • the foil deflectors can also be designed as air duct channels, e.g. in the form of tubes or openings, so that air can be blown under the shrink hood during most of the shrinking process.
  • the surface of the film bumpers can be coated with PTFE polytetrafluoroethylene.
  • the foil deflectors can have a holding device for the lower edge of the shrink hood, so that the shrink hood pulled over the stack of goods does not slide upwards during shrinking: if the pallets with stack of goods are also to be given a lower shrink, then the device can also be equipped with a lifting device for lifting the pallet. In this case, the foil deflectors should be movable in the same direction as the pallet moved by the lifting device.
  • a conveyor 1 is shown on which pallets 2 with a stack of goods 3 arranged thereon are transported from bottles.
  • a film 4 On the top of the pallet 2 is a film 4, which protrudes beyond the edge of the pallet.
  • the stack of goods 3 is arranged on the film 4.
  • the stack of goods 3 and the pallet 2 are to be covered with a shrink hood 5 and shrunk in such a way that the shrink hood 5 is welded to the edge of the film 4 and, at the same time, a lower shrinkage is formed under the underside of the pallet 2.
  • a device for covering the stack of goods with a shrink hood In the area of the conveyor 1 there is a device for covering the stack of goods with a shrink hood. Of this device, only grippers 6 are shown, which grip the lower edge 7 of the shrink hood 5 and pull the open shrink hood 5 over the stack 3 of goods.
  • the lower edge 7 of the shrink hood 5 is also pulled over film deflectors 8 arranged on both sides of the conveyor 1, which are pivotally mounted laterally on the conveyor 1 and with the aid of a drive 9, which in the embodiment shown is a compressed air cylinder, in the direction of the double arrows 10 in Fig. 2 are pivotable.
  • the film deflectors 8, of which only one is shown in FIG. 1 are pivoted up onto the stack of goods 3 before the shrink hood 5 is pulled over. They remain in this position even when the grippers 6 have released the lower edge 7 of the shrink hood 5 and have returned to their starting position.
  • the shrink hood 5 can be shrunk - with a frame-shaped shrinking device, the frame of which is somewhat larger than the base of the stack of goods 3 and hot gas is blown from the frame rods onto the shrink hood 5.
  • the shrinking device moves from top to bottom along the stack of goods 3.
  • air is blown under the shrink hood 5 via the foil deflectors 8, which are hollow in the embodiment shown, so that a uniform shrinkage and a wrinkle-free application of the Shrink hood 5 is reached on stack 3.
  • the foil deflectors 8 also have a surface layer of PTFE, so that the heated material of the shrink hood 5 does not get caught on them.
  • the film deflectors 8 can be provided with holding devices or a roughened surface so that the lower regions of the shrink hood 5 do not slide upwards when shrinking.
  • a lifting device 12 is provided in the area of the conveyor 1 or between the two conveyor tracks, with which the pallet 2 can be raised as shown, so that the underside of the pallet 2 is free. This gives the possibility of producing a shrinkage by which the stack of goods 3 is additionally held on the pallet 2.
