Definitions

  • the invention relates to a device for covering and shrinking stacks of goods with shrink hoods, with a parking space or a conveyor for the stack of goods and a device arranged above for pulling a film tube from a reel, wherein a section separated from the film tube and provided with a head weld seam as a shrink hood of is pulled over the stack of goods above and is subjected to heat energy on all sides with a frame-like, vertically movable shrinking device.
  • stacks of goods can largely be automatically provided with shrink hoods and shrink-fitted.
  • the film tube drawn off from a roll passes a spreading device above the stack of goods and is thereby opened so that it can be pulled over the stack of goods.
  • the head weld seam is placed at the same time, so that the shrink hood is closed at the top.
  • the shrink hood is then shrunk by supplying thermal energy. This can be done by infrared radiation or with the help of hot air.
  • the frame-like shrinking device is guided in the vertical direction over the stack of goods provided with the shrink hood, thermal energy being emitted and the shrink hood being shrunk.
  • the object of the invention is to avoid premature shrinkage of the shrink hood or the film tube.
  • a nozzle arrangement for producing an air curtain extending essentially horizontally through the device is provided below the device for pulling off, but above the range of movement of the shrinking device, and in that a fan is assigned to the nozzle arrangement.
  • This air curtain which extends horizontally above the stack of goods and horizontally through the device, takes the rising warm air with it and removes it, so that it can no longer reach the area of the device for pulling off the film tube.
  • the nozzle arrangement is expediently in the region of a Arranged side of the device and on the opposite side a hood with a drainage channel is provided.
  • the collecting hood and the exhaust duct prevent the air flow of the air curtain and the warm air entrained by it from moving uncontrollably in the room. Possibly. a suction fan can also be connected to the exhaust duct.
  • the nozzle arrangement and an associated blower are expediently fastened to a frame on which the shrinking device is also guided. This enables a compact construction of the device as well as retrofitting of devices in which a nozzle arrangement with a blower was previously missing.
  • the nozzle arrangement can be a slotted tube, the outlet slot of which is directed towards the collecting hood and has a length which corresponds at least to the assigned dimension of the shrinking device.
  • the outlet slot of which is directed towards the collecting hood and has a length which corresponds at least to the assigned dimension of the shrinking device.
  • other types of nozzle arrangements are also possible if it is only ensured that the air curtain thus produced extends continuously across the width of the shrinking device
  • the device shown is located in the area of a conveyor 1, on which palletized stacks of goods 2 are moved, which are to be covered with a shrink hood, which is then shrunk on.
  • the device includes a portal-like frame 3 with frame posts 4, 5 and an upper frame cross member 6.
  • a device 7 for pulling off the film tube 8 from a winding 9 is arranged on the upper frame cross member 6. As indicated in the drawing, the film tube 9 is guided via a plurality of deflection rollers 10 to a spreading device 11, which is only indicated.
  • the spreading device also includes a separating welding device, not shown, which separates a section from the film tube 8 and provides this with a head weld. The section separated from the film tube 8 forms a shrink hood, which is then pulled over the stack of goods 2 from above.
  • a vertically up and down movable carriage 13 is guided on a column 12 or the like arranged next to the frame 3 and carries a shrinking device 14.
  • the shrinking device has the shape of a frame, the inner opening of which is larger than the base area of the stack of goods 2, so that the shrinking device 14 can be moved up and down in the vertical direction, surrounding the stack of goods.
  • the shrinking device can work with infrared rays or with hot gas.
  • a blower 16 is arranged on a bracket 15 of the column 12 and is connected to a slotted tube 17, which is located below the upper frame cross member 6 but above the uppermost operating position of the shrinking device 14 and extends in the horizontal direction.
  • the tube 17 is attached to the frame stem 5 in the embodiment shown.
  • the length of the tube corresponds at least to the corresponding dimension the shrinking device 14.
  • a catch hood 18 is arranged on the frame stem 4, from which a discharge duct 19 extends.
  • the catch hood 18, which in the embodiment shown has a grating 20 on the inlet side, extends essentially parallel to the tube 17 and has a corresponding length.
  • the outlet slot 21 of the tube 17 extends substantially over the entire length of the tube 17 and is directed towards the hood 18.
  • the warm gases rising during operation of the device are detected by an air curtain 22 emerging from the outlet slot 21 and passed to the hood 18, from which they are drawn off via the exhaust duct 19 be dissipated. Accordingly, the hot gases can no longer reach the area of the upper frame cross member 6 and the devices arranged there.
