Definitions

  • the invention relates to a device for shrinking shrink hoods that surround a palletized stack of goods, with a shrinking device, with a transport system for the palletized stack of goods that leads past the shrinking device, with a lifting device arranged underneath the shrinking device for lifting the palletized stack of goods, and with one in the area the lifting device arranged suction fan.
  • the palletized and possibly already provided with a shrink hood stack of goods are brought on a conveyor, for example a roller conveyor, into the area of the shrinking device.
  • a conveyor for example a roller conveyor
  • the palletized stack of goods is lifted with a lifting device arranged under the conveyor, which is designed as a scissor lifting table, so that the lower edges of the shrink hood are free above the underside of the pallet hang.
  • the suction blower arranged on the scissor lifting table the free edges are then sucked against the underside of the pallet and shrunk using the shrinking device, so that a so-called undershrinkage occurs.
  • the palletized stack of goods is put back on the roller conveyor and the rest of the shrink hood shrunk.
  • the object of the invention is to improve a device of the type described in the introduction in such a way that, when using transport systems with in particular driverless, automatically controlled industrial trucks, devices arranged under the floor can be dispensed with.
  • the lifting device is arranged next to the path of the transport system and has at least one lifting and lowering carrier which can be moved up to below a palletized stack of goods brought up by the transport system, the carrier having protruding supports for the stacked stack of goods and the supports from a horizontal in a vertical position can be moved.
  • the entire lifting device is thus arranged next to the path of the transport system and below the shrinking device, so that the effort for a pit and the units to be accommodated therein is superfluous.
  • the supports can be placed under the pallet in such a way that the pallet and the stack of goods on it can be lifted off the surface of the cart.
  • the trolley or trolleys on which palletized stacks of goods are brought in have storage areas which are designed in such a way that the supports can act on the underside of the pallet.
  • the control of the pivoting movement of the supports becomes particularly simple if two or more supports are provided and the supports can be pivoted about their longitudinal axes. Then the supports can be rigidly attached to the beams.
  • the carriers should preferably be displaceable in the direction of their longitudinal axes, that is to say transversely to the path of the transport system.
  • the carriers can be mounted in a drive housing which has drives and guides for the longitudinal displacement of the carriers and for their pivoting movement and which in turn can be moved vertically up and down on a stand. Since in most cases the shrinking device is also guided on one or more vertical stands, the drive housing can also be guided on the stand or stands of the shrinking device.
  • the or Carriers consist of pipes which are connected to the suction fan and have air inlet openings.
  • the device shown in the drawing serves to shrink shrink hoods that surround a palletized stack of goods.
  • Good stacks 1 are arranged on a pallet 2, which are placed on the storage space 3 of a cart 4.
  • One or more carts 4 are towed by an electric tractor, not shown, which can be controlled and stopped and started through the factory floor via induction loops laid in the floor.
  • a cart 4 loaded with a stack of goods 1 is stopped in front of a shrinking device.
  • This shrinking device includes one or more vertical stands 5, on which a shrinking frame 6 can be moved up and down.
  • the shrink frame 6 has an inner opening which is somewhat larger than the cross section of the stack of goods 1.
  • heating devices e.g. Burners, the hot combustion gases of which are directed onto the stack of goods 1, so that when the shrinking frame 6 moves up or down, a shrink hood surrounding the stack of goods 1 is shrunk.
  • a drive housing 7 is guided vertically up and down.
  • Two mutually parallel supports 8 are held in the drive housing 7, only one of which is visible in the drawing.
  • the carrier 8 can be shifted horizontally so far in the direction of their longitudinal axes with the aid of associated drives, which are not shown, that they either take the drawn position or are outside the cart 4.
  • the carriers 8 can also be pivoted about their longitudinal axes with the aid of associated drives.
  • each carrier has two spaced-apart supports 10 which project radially from the carrier 8. By pivoting the carrier 8, the supports 10 can be brought from a horizontal position into the vertical position shown.
  • the carrier 8 consist of tubes with air inlet openings 11 on the section which is in the functional position shown below the pallet 2.
  • the tubular carrier 8 are connected to a suction fan, not shown.
  • the device shown works as follows: A cart 4 loaded with a stack of goods 1 is stopped in front of the shrinking device.
  • the carriers 8 are moved in the direction of their longitudinal axis through corresponding, not shown recesses of the cart 4 in the cart to below the pallet 2, the supports 10 being in the horizontal position. Then the carriers 8 are given about their longitudinal axes until the supports 10 assume a vertical position, which is shown in the drawing.
  • the footprint 3 of the trolley has corresponding recesses so that the supports 10 can be pivoted into the vertical position in order to be able to grasp the underside of the pallet 2 with the aid of the drive housing 7 after the carrier 8 has been raised.
  • the pallet 2 with the stack of goods 1 located thereon is removed from the storage space 3 of the cart 4 lifted, until the edges of a shrink hood, not shown in the drawing, pulled over the stack of goods 1 and the pallet 2 hang freely below the underside of the pallet 2.
  • the suction fan which sucks air through the air inlet openings 11 of the tubular carrier 8 from the underside of the pallet, the freely hanging edges of the shrink hood lie under the underside of the pallet.
  • the shrink hood can be shrunk, either the pallet 2 with the folded edges of the shrink hood is first placed back on the shelf 3 or and first the edges of the shrink hood folded under the underside of the pallet are shrunk.
  • the supports 8 are lowered to such an extent that the supports 10 can be brought back into a horizontal position by pivoting the supports 8.
  • the carriers 8 are then pulled longitudinally out of the area of the cart 4, which can then continue to move.
