Definitions

  • the invention relates to a device for wrapping objects with a helix of a re-shrinkable film that can be peeled off a supply roll, the device having a roll guide device that is equipped with a supply roll and encompasses the articles in a frame-like manner, through which the articles are moved supported and on which the supply roll during of wrapping is mounted on a fixed path around the objects so as to be movable at a distance from them.
  • Such a device is known from DE-A 2 303 590, FIGS. 1 and 2.
  • the known device is used for objects of various shapes, e.g. Wooden bundles, window and door frames, paper rolls, sleeves, pipes, shaped steel, newspapers, magazines, etc., by wrapping with packaging material to form a package unit.
  • a stationary rotating frame which only partially encompasses the objects to be encased.
  • two supply rolls run on sled-like devices in a swinging manner around the axis of the objects.
  • a wrapping tape is attached to the lower edges of the objects to be wrapped. The film is then pulled over the top of the objects and also attached to the opposite lower edge.
  • a disadvantage of this second embodiment is that the fastening of the film requires an additional stop device and that the device is therefore more expensive.
  • Another disadvantage is that no opposite, continuous helix can be wound.
  • a device of the type mentioned at the outset which is characterized in that a second supply roll equipped with a film is provided on the roll guide device, the rolls being arranged in opposite directions on the front and rear sides of a common rotary frame.
  • the items to be encased include parcels and containers in particular, these terms characterizing two different types of items to be encased: “package” is understood to mean a more or less closed, possibly bulky, but not falling apart structure, for example a carpet roll, while a “package” »A structure is to be understood that is stacked out of cardboard boxes, objects or the like, which can be knocked down from its base under the influence of light force, for example through the wrapping film itself, or move without a base, so that the « package »is no longer has the original shape to be encased.
  • the drawing shows in perspective a device for wrapping packages 1.
  • the device has a roller guide device 2, with which a tape of a wrapping film 3, 3 'can be pulled off two supply rolls 4, 4'.
  • the supply rolls 4, 4 ' are each mounted on a rotating rim 5, 5' with a flying axis.
  • Each of the two rings 5, 5 ' is provided with a ring gear on its outside.
  • the two rings 5, 5 ' are rotated in opposite directions via two drive pinions 6, 6' which rotate in opposite directions but are driven by the same motor. Viewed in the direction of conveyance, the ring 5 rotates clockwise and the ring 5 'counterclockwise.
  • Two conveyor belts 7 and 8 are arranged in front of and behind the guide device 2 equipped with the two rings 5, 5 '.
  • a bridging conveyor (not shown here) can also convey the package or a container through the rings 5, 5 '.
  • Such bridging conveyors are known from DE-OS 3 119 657. This also allows shorter objects to be transported, the bridging conveyor belt and the objects being wrapped in the film as the process progresses.
  • the guide device 2 is surrounded by a holding frame 10.
  • the guide device 2 with the rotating rings 5, 5 'and the associated drive device is held by a supporting wall 11 which extends between the periphery of the rings 5, 5' and which has support devices (not shown) for the rings 5, 5 '.
  • the means for rotating the rings 5, 5 'and for transporting the enveloping objects are known per se.
  • the film 3, 3 ' is a stretch film, that is to say a re-shrinking film, which is pulled under tension by one of the supply rolls 4, 4', the supply rolls 4, 4 'rotating in opposite directions during wrapping on a fixed track.
  • a distance is kept from package 1: Package 1 is transported during wrapping, so that there are two layers of wrapping foil lying one on top of the other with an opposite slope.
  • the tension and the circulation speed of the supply rolls can be varied; however, the two supply rolls preferably run synchronously and with the same tension. This also means that the two rings 5, 5 'run in opposite directions and synchronously with the supply rolls 4, 4', being offset by at least one film width in the conveying direction.
  • the winding axes of the supply rolls are inclined to the axis of rotation of the rings 5 or 5 'by an angle between 2 - 20 ° from the parallel orientation, namely the roll 4 away from the package and the roller 4' towards the package.
  • This inclination of the roller axles means that the film is applied to the package without any wrinkles and without the need for additional guide and guide rollers.
  • the film pre-tension which depends on the circumstances and the composition of the film material, to be different in the two films, for example the first winding film 4 'with a slightly lower winding tension and the subsequent film 4 with a somewhat higher winding tension to wrap.
  • different film widths for example initially narrow (roll 4 '), then wide (roll 4), can be provided.
