Definitions

  • the invention relates to an apparatus and a method for packaging flat objects, in particular flat, flexible printed products, according to the preamble of the corresponding independent claims.
  • EP 0 397 580 shows a handling device for bottles, which partially enveloped with a shrink wrap in the device arrive.
  • grippers for holding the transported bottles, which are designed to rotate the bottles in a horizontal position.
  • the bottles must be stiff, and the bottle can not in the area in which it is covered by the shrink film, be grasped.
  • the rotation of the bottle in the horizontal position is required so that the bottle is heated evenly when entering a heat tunnel for shrinking the shrink film lengthwise .
  • DE 26 10 051 also discloses a handling device for bottles, which are partially covered with a shrink film.
  • a specially shaped nozzle device causes a selective shrinking of the shrink film in a first region, so that the shrink film is fixed during further transport to the complete shrinking.
  • EP 0718 198 shows a packaging device for producing a shrink wrap and then shrinking, but without transporting objects by means of grippers
  • the flat objects are thus gripped through the enclosure (indirectly).
  • the apparatus for packaging flat objects accordingly comprises: a foaming unit for wrapping successive flat objects with a foil wrapping; a first conveying device for gripping the completely enveloped flat objects each with a gripper and for transporting the enveloped flat objects to a shrinking unit, the shrinking unit being spatially separated from the filming unit; wherein the shrinking unit is adapted for shrinking the film wrappings onto the flat objects.
  • a distance between the foiling unit and the shrinking unit is at least 2 meters or at least 10 meters.
  • the flat articles are held and transported by the grippers of the first conveyor, preferably in a vertical hanging position, or they are transferred to a second conveyor prior to shrinking the film wrappings.
  • the flat articles are transported by the second conveyor. This makes it possible to adapt the second conveying device to constructive conditions of the shrinking unit and / or to avoid damaging the first conveying device by the shrinking unit.
  • the flat objects are returned to the first conveyor by the second conveyor.
  • the transfer of the flat objects from the first to the second conveying device is preferably selectively switched on and off.
  • an excess of the unshrunk film wrapping and the parameters of the shrinkage are coordinated so that the film wrapping is free from tensile stresses after shrinking, ie that a tensile stress in the Film wrap after shrinking is substantially zero. This prevents that a flexible printed product is contracted by the tension of the film wrapping and bends or curls.
  • the conveying device runs in at least one section between the filming unit and the shrinking unit in a path above a head level and / or is fastened to a building ceiling.
  • the conveying device thus extends at least 2 m to 3 m above ground level.
  • the conveyor is locatable so that it does not collide with other units or passes.
  • the shrinking unit is also arranged above the head height and / or attached to a building ceiling. This makes a space-saving design of the system possible.
  • the shrinking unit is arranged below the head height and conveys the first conveyor or a second conveyor the flat objects from the height above the head level to the height below the head level.
  • FIG. 1 shows an overview of a device according to the invention.
  • a foiling unit 1 is arranged to foil a series of flat objects 5. These are then, completely enveloped by a film wrapping 6, transported by gripper 4 a first conveyor 2 to a shrinking unit 3 and through the shrinking unit 3 therethrough.
  • the shrinking unit 3 heats to shrink the Folienumhüllung, for example by means of heat radiation or by means of heated air, which is heated by means of electrical energy or gas or oil and blown against the enveloped flat objects 5.
  • FIG. 1 the shrinking unit 3 is shown in an overhead arrangement.
  • FIG. 2 shows a further variant for feeding a shrinking unit 3, in which the shrinking unit 3 is mounted at ground level, and the first conveyor 2 is guided by an overhead course back down to the height of the shrinking unit 3.
  • the first conveyor transports the flat objects 5 with the grippers 4 through the area of the shrinking unit 3
  • the shrinking unit 3 is preferably designed to heat the flat objects 5 and the film wrapping 6 less strongly in the area of the grippers 4 than in other areas of the flat objects 5 or of the film wrapping 6.
  • the shrinking unit 3 itself has additional gripping means or holders 4 '(shown schematically and dashed). These are arranged and controlled for temporarily holding and transporting the flat objects 5.
  • the additional holders 4 ' hold and transport the flat objects 5 in a transporting section in the shrinking unit 3 in synchronism with the grippers 4 for a certain period of time.
  • the additional holders 4' hold the articles 5, for example, from one or both sides, or from above but next to the gripper 4.
  • the gripper 4 of the conveyor 2 temporarily releases the flat articles 5 within this period of time. This makes it possible to better suspend and shrink the portions of the film 6 held and covered by the grippers 4 from the heat of the shrinking unit 3.
  • FIG. 3 shows a second variant for feeding a shrinking unit.
  • a second conveying device 7 for transporting the flat objects 5 through the region of the shrinking unit 3 is arranged.
  • a transfer device 9 is arranged for transferring the flat objects from the first conveying device 2 to the second conveying device 7, and a receiving device 10 for receiving the flat objects 5 by the first conveying device 2 from the second conveying device 7.
  • the second conveying device 7 thus forms a bypass Route 8 or diversion from the first conveyor 2 by the shrinking unit 3.
  • the second conveyor has, for example, a conveyor belt 11 for transporting the flat objects through the shrinking unit.
  • a further conveying means in particular a further conveyor belt 11 ', which subsequently transports the flat objects 5, is subsequently arranged on the conveyor belt 11.
  • a switchable deflection device which selectively directs the flow of the conveyed objects 5 back to the conveying device 2 or leaves it on the further conveyor belt 11 '.
  • the transfer device 9 is switched on and off, wherein when switched handover the flat objects 5 are transferred to the second conveyor 7 and are switched off handover the flat objects 5 by the first conveyor 2.
  • the switching on and off of the transfer device 9 is also a coordinated, i. Delayed switching on and off of the receiving device 10 connected in accordance with the transport speed.
  • FIGS. 4a and 4b show a held in a gripper 4 foiled article 4 before and after shrinkage.
  • the film 6 is relatively loosely around the object 5.
  • the film 6 is shrunk onto the article 5 and fits closely against it, preferably with a low tension, so that a bendable article 6 is not bent by the tension of the film 6.
