  • a film tube is placed in a processing room supplied in the desired length, welded to a film hood and cut off the formed film hood. Then the film hood opened and with grippers of the shrink frame over the object to be packed drawn. In order to shrink the film hood onto the object then the shrink frame, the one the object to be packed in a ring surrounding heater means from the bottom portion of the article moved up again. The heating device is switched on, see above that the film hood with the application of heat to the object to be packaged is shrunk.
  • the film hood is pulled over shrunk over the object to be packed.
  • This will make the the two process steps of covering and shrinking are summarized in time, so that the cycle times of the process are shortened and the Performance is increased.
  • suction of air or there is no need to inflate the film hood during the shrinking process the shrinking takes place while the film hood is pulled over the object becomes.
  • This also enables a particularly uniform and reliable Shrinking the film material, which prevents wrinkling.
  • the film hood is by means of a heating device by supplying heat above a gripping device shrunk the item. This enables an effective and consistent Shrinking process, because when shrinking the heating device in a fixed Distance to the gripping device and the film wall can be positioned.
  • Heat is preferably applied to the film hood before it contacts the Has created object so that the pulling of the film hood over the Object runs essentially without contact. This prevents any Damage, such as cracks or the like, when the film hood is pulled over. Furthermore, the Shrink the film hood wrinkle-free onto the object, reducing its mechanical Properties, especially the tear strength improved.
  • the heat supply is Shrinkage of the film hood controllable, so that objects with irregular Surfaces can be shrunk better.
  • the distance between the film hood and the heating device changes, so that an individual adjustment of the heat supply is required for certain areas is.
  • the film hood is first applied the top of it shrunk onto the object and then the heater together with a gripping device that reefs the film hood State holds, moved down. This results in a particularly tight fit the film hood on the object.
  • a further increase in performance can be achieved if the film hood is opened by a first gripping device and then to a second gripping device is passed.
  • the second gripping device can then initiate the shrinking process together with the heater while the The first gripping device pick up the subsequent film hood and place it in the reefed Condition.
  • the film hood is on the underside of the object sucked inwards and at least partially on the underside of the object shrunk so that the seat of the film hood is particularly firm becomes.
  • the film hood can bottom area to be welded with a bottom film. This allows also achieve sealed packaging of the item.
  • the film hood can be shrunk onto the heated one Area to be cooled. This enables a particularly large one Heat supply in a short time, since the excess heat is dissipated quickly can.
  • the heater when the film hood is pulled over over the object the heater at a fixed distance above a gripping device for covering the film hood. This makes possible a simultaneous covering of the film hood and shrinking it on the object. It can also be reliable and fast Carry out shrinking because the distance between the film hood and the heating device especially for objects with irregular surfaces, relative is even. This enables wrinkle-free shrinking and provision a resilient shrunk film hood.
  • the gripping device for covering the film hood on the shrink frame connectable or connected to this. In both cases, the distance of the Gripping device to the heater on the shrink frame quickly and fix in a simple way.
  • the device preferably has a first movable gripping device for Opening the film hood and a second movable gripping device for pulling over the film hood so that the gripping devices can work in parallel and are individually adapted to their respective task.
  • the first gripping device has a plurality of suction boxes for opening the film hood, while the second gripping device is connected to the shrink frame can be.
  • the shrink frame has In addition to the heating device, a cooling device with which a rapid cooling of the film hood is achieved after shrinking. This enables an intensive supply of heat and a shortening of the timeshrinking process.
  • a heat shield is provided so that the opening of the film hood can take place in a relatively sheltered cooler room and sticking the following slide can be prevented.
  • a stack of goods 1 is on a pallet 2 arranged so that pallet 2 and stack of goods 1 the object to be packed form.
  • the pallet 2 is arranged on a vertically movable lifting table 3, which component e.g. a belt conveyor system and which is on a base part 4 is stored.
  • the object to be packaged is arranged within a frame 5 which the individual components of the device are at least partially suspended.
  • the film to be fed is unwound from a film roll 6 and in shape a film tube 8 via feed rollers 7 to the upper area of the Packing device led.
  • the upper area of the device forms a processing station 9, in which the film tube 8 to a film hood 20 with the desired length is formed.
  • gripper fingers 103 are placed in the film tube. Through on the gripper fingers 103 arranged reef rollers 11, the film tube 8 on the gripping fingers 103 funded.
  • the film tube 8 When the film tube 8 has reached the desired length, it is cut off by a cutter 12 and by one below it horizontal welding device 13 welded together so that a film hood 20 is formed.
  • the first gripping device consists of four suction boxes 100, which are attached to the respective Grasp the corners of the film tube to open it. On one edge of the Suction box, a gripping device 101 is provided with which the corresponding Foil tube edge can be pinched. Then the four Suction boxes 100 each moved on two parallel axes 102 such that the opened film tube essentially the contour of the object to be packaged Has. A detailed description of the opening system is in DE 43 26 827 to find.
  • the first gripping device is preferably corresponding the suction / gripping device disclosed there. However, it is also possible to use other mechanical opening systems.
  • the film hood 20 thus formed essentially the contour of the has taken packaging object, it is sent to a second gripping device to hand over.
  • the second gripping device has four grippers 16, which on one Shrink frames 15 are arranged.
  • a heat shield 14 is provided which Processing station 9 separates from the shrink space to the subsequent film hood not to be glued by rising heat.
