Definitions

  • the invention relates to a method for wrapping a stack of goods with a tubular or hood-shaped stretch film by means of a Strechtfolienverpackungsstrom with the process steps, transverse stretching of the stretch film to a greater extent than that of the stack, and coating the stretch film on the stack in a coating direction, wherein during the coating the stretch film is relaxed for wrapping the stack in the transverse direction.
  • a device and a method for wrapping preferably palletized piece goods are known.
  • a stretch film in the form of a hood is pulled over a stack of goods.
  • the device has a magazine which receives a roll of a wound stretch film in the form of a tube.
  • a required length of the stretch film is picked up on a gripping device and welded at an upper end and cut off above the weld, so that forms a film hood.
  • the film hood thus formed is transversely rectangular by means of grippers, so that the stretch film has a larger circumference than the stack. In an unstretched condition, the circumference of the stretch film is less than that of the stock pile.
  • the film hood is pulled over the stack, wherein the stretch film is continuously withdrawn from the gripper device.
  • Both for refeeding to the gripping device and for removing the stretch film from the gripping device can be provided on the gripping device Reffrollen.
  • the stretch film contracts again and envelops the stack.
  • the movement of the gripping device is here vertically from top to bottom. To ensure the most complete possible wrapping of the stack, the stretch film is pulled all the way down.
  • the stack comprises a pallet on which parcels are piled up, the stretch film being pulled up to the pallet.
  • Object of the present invention is to achieve a packaging unit of a stack and a stretched over stretch film, which protects the cargo of the stack as well as possible and also ensures a high stability of the stack.
  • the object is achieved by a method for wrapping a stack of goods with a tubular or hood-shaped stretch film by means of a Strechfolienverpackungsstrom with the process steps, transverse stretching of the stretch film to a greater extent than that of the stack, and coating the stretch film on the stack in a coating direction, wherein during the Covering the stretch film is relaxed to wrap the stack in the transverse direction, solved. Subsequently, the stretch film is pulled over at least part of the already wrapped stack of goods against the coating direction.
  • a double layer of stretch film is achieved.
  • a threefold layer can be achieved in that, subsequently, the stretch film is slipped over the already wrapped stack again in the overstretching direction. This movement against the coating direction and in the coating direction can be joined several times to form a corresponding number of layers of the stretch film.
  • the stack comprises a pallet on which stacked cargo of the stack is applied.
  • the stretch film can be covered over the cargo and at least partially over the pallet in the coating direction.
  • This lower region of the stack is thus particularly protected by the multi-layered wrapping.
  • the stack is most at risk of suffering external damage, since at this height the forks of forklifts are arranged when forklifts are moved.
  • the multi-layered stretch film in the lower portion of the stack thus reduces the risk that the envelope of the stack will be punctured when a forklift truck accidentally hits the stack with the forks.
  • Another advantage is that overall a thinner stretch film can be used.
  • the thickness of the stretch film does not have to be adjusted to the highest loaded area overall.
  • An inlay can thus be provided in an upper region, whereby the number of layers can increase towards the bottom.
  • a single-ply wrapper may be formed in an upper portion of the stack and a multi-ply, e.g., three-ply, wrapper may be formed in a lower region near the pallet.
  • a three-layer layer is provided in a middle region and in a lower region an overlying number of layers, for example five.
  • the entire stretch film would have to be made as thick as the multi-layer wrapper according to the invention to ensure comparable stability.
  • this would mean that the thick stretch film material is also present in the safe areas and thus more film material is consumed.
  • the stretch film can be picked up on a gripping device and transversely stretched from this.
  • the gripping device is moved in the direction of over the stack, wherein the stretch film is continuously withdrawn from the gripping device.
  • the arrival of the stretch film can be done by Reffrollen on the gripping device.
  • the gripping device can preferably be moved vertically from top to bottom over the stack.
  • the invention further relates to a computer program having a program code for carrying out the method described above when the computer program is executed on a computer or processor of the stretch film packaging installation.
  • the invention comprises a packaging unit, which comprises a stack of goods with a pallet and stacked on the pallet, a tubular or hood-shaped stretch film, which is covered over the stack and the stack at least partially wrapped in a coating direction, wherein at least a portion of the stack in Covering direction seen in several layers is wrapped by the stretch film.
  • the stack may be repeatedly coated with stretch film in the region of the pallet and at least in a partial region of the article adjacent to the pallet.
  • FIG. 1 shows a stretch film packaging machine 1, which has a main frame 2, which stands on the floor and defines an inner working space 3. In the working space 3, a stack of goods, not shown here according to the FIGS. 2 to 6 be packed.
  • the stretch film wrapping machine 1 further comprises a gripping device in the form of a stretch frame 4, which can be moved on the main frame 2 in the vertical direction in a coating direction Z from vertical from top to bottom and against the coating direction Z from bottom to top.
  • a film magazine 6 is provided, which receives a stretch film roll 7. From the stretch film roll 7, a stretch film 8 in the form of a folded hose is fed to a feed unit 9 of an upper frame of the stretch film packaging installation 1.
  • the feed unit 9 comprises drive rollers with which the stretch film 8 is unwound from the stretch film roll 7.
  • FIGS. 2 to 5 schematically show the packaging process within the working space 3.
  • a stack 11 is retracted, comprising a pallet 12 and stacked on the pallet 12 piece goods 13.
  • the feed unit 9 conveys the stretch film 8 vertically from top to bottom to the stretch frame 4.
  • the stretch frame 4 comprises four grippers 10, 10 ', 10 ", 10''' which are arranged so that they form a rectangle , 10 ', 10 ", 10''' serve to engage the tubular stretch film 8 and open the stretch film 8.
  • the circumference of the tubular stretch film 8 is less than the outer circumference of the stack of goods eleventh
  • the stretch frame 4 (gripping device) has here not shown Reffrollen, with which a predetermined length of the stretch film 8 auffrefffft on the stretch frame 4, as in FIG. 3 is shown.
  • the upper frame 5 here schematically illustrated welding bar 14, with which the stretch film 8 is welded and is separated above the weld.
  • a stretch hood 15 arranged on the stretch frame 4 is formed ( FIG. 3 ).
  • the stretch hood 15 formed by the stretch film 8 is stretched transversely to the coating direction Z along the illustrated arrows in such a way that the stretch hood 15 has a larger circumference than the product stack 11.
  • the stretch frame 4 After reaching a predetermined vertical position in coating direction Z, the stretch frame 4 is moved counter to the coating Z over the already wrapped stack 11, so that the stretch film 8 covers the already wrapped stack 11 a second time and results in a two-ply enclosure. Following this, the stretch frame 4 can also be moved back and forth in overdrawing direction Z and possibly also several times in order to achieve a corresponding number of layers.
  • the multi-layered portion of the envelope is in the region of the pallet 12 and the at least lower portion of the piece goods 13 stacked on the pallet 12.
  • the multi-layer is schematic in FIG. 6 shown.
  • a section of a lower corner of the stack 11 is shown.
  • the stretch film 8 As it encloses the stack 11.
  • An inner first layer 16 of the stretch film 8 is pulled vertically down to the lower end of the pallet 12.
  • the stretch film 8 was again pulled against the coating direction Z up over the stack 11, so that there is a middle second layer 17.
  • the Slide 8 pulled back in overdrawing Z down over the stack 11, so that there is an outer third layer 18.
