Definitions

  • the invention relates to a method for packaging objects according to the The preamble of claim 1 and a device for packaging objects according to the preamble of claim 7.
  • Such devices and methods are used in particular for packaging stacks of goods arranged on pallets used to protect the stack of goods from moisture and during transport to give other environmental influences.
  • the wrapping of the stack of goods gives with a film hood of the packaging unit increased stability, in particular when the film hood is stretched in the transverse and longitudinal directions when covering and after tensioning it is under tension against the stack of goods.
  • EP-A-0 633 186 discloses a method and a device for wrapping of general cargo, in which a stretch film is drawn over a stack of goods becomes. To do this, first a film tube of the desired length is closed welded to a film hood and cut off above the weld. The The film hood thus formed is arranged on four rectangularly by means of reefing rollers Gripping devices raised and stretched into a shape slightly larger than that Cross section of the stack of goods to be packed. Then the film hood pulled over the stack of goods by a downward movement of the gripping devices and stretched in the longitudinal direction, with the bottom of the stack of goods the film hood is provided with an understretch. This understretch is produced in that the film against the gripping devices by means of the reefing rollers is pressed and held and in this state opposite the overlay contour is moved inwards, especially under the pallet.
  • This method has the advantage that the film hood does not immediately after Covering can slip up again.
  • the holding force that comes with the reef rolls can only be generated slightly.
  • the holding force of the reef rollers is proportional to the contact pressure on the bracket-like frame section and the Friction coefficient between the film hood and reef roller. Too much pressure can cause damage to the film hood, especially if the Refrolling only an essentially selective force when pressed onto the film exercise. Furthermore, holes can be created in the film hood by pressing become.
  • DE 90 01 319 U1 describes a further device for packaging objects known to be used in the movable jaws to the film hood to press against the stack of goods in a lower area. This too The procedure prevents the film hood from sliding up, but it can easy to undesirable damage to the film hood and the packaging material to lead.
  • the bow-shaped Frame sections can be folded down relative to the frame supports the film under the influence of the transverse stretching forces in the gap between the Pull in the frame supports and the folded down bow-shaped frame sections.
  • the frictional forces between the film and the gripping devices when pulling off significantly increased so that the film is not too early slides down from the gripping devices before they fully adhere to the stack of goods or / and has created the pallet. It becomes a perfect understretch generated, and the need is eliminated, the film hood on the packaged Object or / and to press the pallet and gripping devices to a Avoid slipping up the film hood.
  • the foil hood applied over entire surface sections by means of frictional forces, so that selective Loads and thus damage to the film hood can be avoided.
  • Each bow-like frame section preferably moves in relation to one Edge of the object to be packaged, and a film section of the film hood is guided around this edge. This way of guiding the film hood prevents the tensile forces to generate the Unterstretches only selectively attack as is the case when a reef roll from the outside on the bracket-like Frame section is pressed to the film hood on the bracket-like frame section to keep. When the film section is at a certain angle extends, therefore reduces the load on the film hood.
  • the understretch is carried out moving the gripping devices relative to the pull-over contour of the film generated inside, in particular under the object to be packaged.
  • the object when pulling off the film hood from the bow-like frame sections the object opened the bow-like frame sections.
  • the wrap angle the film is thereby enlarged, so that an enlarged friction surface is available to generate the increased frictional forces.
  • the bow-like frame sections preferably have a curved shape, each extending around an edge of the object to be packaged, and the means for guiding the film section are adapted, the film section to let it slide over a curved area. This avoids one punctual loading of the film hood when generating the bottom stretch.
  • Each bracket-like frame section has an easy-to-implement configuration a bracket and a carrier on each other via a folding mechanism are connected.
  • the carrier is on its outer, the Side of the object facing away essentially adapted to the curvature of the bracket, so that the film hood is not torn open at any edges can.
  • the device for packaging objects 1 shown in FIG. 1 has one Supply roll, not shown, for a folded film tube 3, of unwound the supply roll and fed to a central packaging unit becomes.
  • the packaging unit has a frame in which to be packed Objects are transported, and a packaging facility guided on this frame on. From this packaging facility are for the better Illustration only shows the components relevant to the invention.
  • the film tube 3 is turned vertically downward via a deflection rod 4 Welding and cutting device 5 performed. Below the sweat and Cutting device 5, the film tube 3 is opened and moved to four Gripping devices 8 raised by in each case on the outside of the gripping devices 8 a reef roller 10 feeds the film tube 3 to the gripping devices 8. The film tube 3 is then welded to a desired length and cut off, so that a film hood 6 is formed by the four gripping devices 8 stretched into a rectangle and stretched.
  • Each gripping device 8 consists of a bow-like frame section 14, one Folding mechanism 13 and a frame support 15.
  • the frame support 15 is held on an arm 11 which runs along a guide 12 in a horizontal direction is movable.
  • the guide 12 with the arm 11 is also in the vertical direction movable so that the gripping means 8 moves both horizontally and vertically and can be stretched.
  • the bow-like frame section 14 open inwards by the folding mechanism 13.
  • the film hood 6 stretched in the horizontal direction, so that the lower opening of the Film hood 6 slightly larger than the cross section of the stack of goods 1 to be packaged is. In this state, the film takes on its "covering contour". Subsequently the film hood 6 thus stretched is moved downward and onto the stack of goods 1 pulled up, with the welded end of the film hood formed the top of the stack of goods 1 and the film from the gripping devices is withdrawn with friction so that it is stretched in the longitudinal direction.
  • the film hood 6 slides overcoming a frictional resistance from the gripping devices, so that the film hood 6 experiences a certain stretch in the vertical direction.
  • the braking effect can further increased by the application of the reef rollers 10 to a vertical stretch to achieve.
  • the reef roller 10 presses the film hood 6 against the Roll 9. Due to the friction between the braked reef roll 10 and the film. Then the bracket 14 by the folding mechanism 13 inwards and opened up (Fig. 4), so that by a certain relaxation of the film hood 6 a film section in the open gap between the folded part and the frame support 15 arrives. Then the reef rollers 10 are moved outwards. Now the bow-like frame sections are facing down and opposite the covering contour of the film inwards, in particular under the pallet 2 or moves the stack of goods 1 to produce an understretch. It is also possible, the bow-like frame sections 8 in the lateral recesses of the pallet 2 move so that the openings of the pallet 2 remain open for other purposes.
  • the Frame parts are moved so far under the pallet until the lower edge of the The film lies approximately in the plane of the folded-up bow-like parts (Fig. 6).
  • the film then slides off the frame sections and lies on the underside the pallet 1 or the stack of goods 2.
  • a procedure shown in FIG. 7 is alternatively conceivable.
  • the bow-like frame sections 8 are then moved downwards and then outwards to the next film hood to get.
