Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 3 for performing this method. possibly.
  • the stretch hood process As part of the stretch film packaging process that has become known in the meantime, for the formation of loading units (which also includes, for example, a banderole process in which the piece goods to be wrapped are wrapped with the web-shaped stretch film), the stretch hood process has proven to be the creation of transport-safe and weather-resistant loading units proven particularly useful.
  • the present invention is therefore based on the object to improve the known generic methods and devices, in particular while avoiding the disadvantages described above, so that - even with a relatively high pulling speed - it cannot happen that the piece goods or any pallet supporting the piece goods or the like. is not undermined (as provided) with an understretch, this goal being to be achieved with components that are already present.
  • a first solution of the procedural part of the above object consists in the characterizing features of claim 1, while a second solution, which is preferably to be used in combination with the first solution, is characterized by the characterizing feature of claim 2.
  • the solution of the device-related part of the above object according to the invention consists of the characterizing part of claim 3, whereby this solution differs from the prior art according to DE 90 01 319 U 1 essentially in that the already existing reefing device (or whose reefing rollers) is used, so that, to achieve the effect achieved according to the invention, there is practically no significant additional effort. It can only be seen to ensure that the reefing device is to be moved or pivoted accordingly, which can be achieved easily (and with little effort) by appropriate guides.
  • FIG. 1 shows a block-shaped piece goods stack, generally designated 1, which consists of several layers of piece goods parts which are to be wrapped with a stretch film hood 2 in order to form a loading unit.
  • the stretch film hood 2 is formed from a gusseted tube 3, which is fed to the device according to the arrows 8 from a gusseted tube supply (not shown), the free end of the gusseted tube 3 according to FIG. 1 already being provided by a lifting frame designated as a whole by 9 (after the gusseted tube has been spread open) 3) has been included.
  • the gusseted tube 3 is welded at a distance from its free end by means of a welding device 4, which consists essentially of two welding strips, so that a transverse seam 5 is formed, and above the transverse seam 5 by means of a not shown Separating device separated to form a stretch film hood 2, the side surfaces of which, in the state shown in FIG. 2, have already been essentially raised onto the lifting frame 9 (by means of a reefing device).
  • a welding device 4 which consists essentially of two welding strips, so that a transverse seam 5 is formed, and above the transverse seam 5 by means of a not shown Separating device separated to form a stretch film hood 2, the side surfaces of which, in the state shown in FIG. 2, have already been essentially raised onto the lifting frame 9 (by means of a reefing device).
  • FIG. 2 From the state shown in FIG. 2, the four bow-like (lifting) frame sections 9 ′, which essentially form the lifting frame and are assigned to the corner regions of the piece goods stack 1, are moved apart in the direction of the arrows 6 for the purpose of transverse stretching of the stretch film hood 2. After that 4 is stretched over the piece goods stack 1 by means of the lifting frame 9, which at the same time forms a reefing frame, FIG. 4 showing an intermediate state in which the piece goods stack 1 is already half-wrapped.
  • the lifting frame 9 which can be driven by means of a drive (not shown), then moves further downward, finally into a position as can be seen in FIG. 7, only one single bow-like frame section 9 ′ being recognizable in FIG. 7 is, but the other bow-like frame sections 9 'are formed accordingly and are at the same height level.
  • the specific configuration of the bow-like frame sections 9 'of the lifting frame 9 in the illustrated embodiment should be explained in particular in FIGS. 5 and 6, and reference should first be made to the fact that the piece goods stack 1 - As can be seen from FIGS. 1 to 4 - is supported on a (one-way) pallet 10 with a plate top 10 '.
  • the lifting frame 9 consists of four substantially C-shaped bow-like frame sections 9 ', each of which is provided with a plurality of through bores 13, which are connected to a vacuum source, and each engages with one during operation with foils located section of the outside of the relevant lifting frame section 9 'open.
  • the vacuum source indicated schematically in FIG. 6 is designated by 14.
  • Each bow-shaped frame section 9 ' is supported with a support 17 (see FIGS. 5 and 6) formed by a curved, conical sheet metal, the supports 17 each having a recess 18 in the central region. Otherwise, the through bores 13 connected to the vacuum source 14 are connected to a control device 16 (see FIG. 6), by means of which the vacuum can be controlled.
  • the bracket-like frame sections 9 'of the lifting frame 9 are moved in the illustrated embodiment during the pulling process slightly below the top 10' of the pallet 10, with Fig. 7 showing that the already in this intermediate position Side gusset tube 3 or the (side faces of) stretch film hood 2 essentially envelop the piece goods stack. Nevertheless - as can be seen from FIG. 7 - the film 2 or 3, which is still in frictional engagement with the bow-like frame sections 9 'of the lifting frame 9, does not yet adhere to the latter in the region of the lower section 1' and not yet applied to the pallet 10. If, in particular in the case of considerable vertical stretch of the film 2 or 3, the lifting frame 9 was disengaged from the film in the state according to FIG.
  • a pressure device 12 shown schematically in FIG. 7, is provided, in which it is in the illustrated embodiment, the (reefing rollers) of the reefing device, by means of which the gusseted tube 3 has previously been attached to the supports 17 of the bow-like frame sections 9 'of the lifting frame 9.
  • the reefing rollers essentially forming the pressing device 12 are pressed in the position shown in FIG. 7 according to the arrow 15 on the piece goods 1 or in a somewhat lower position on the upper layer 11 of the pallet 10.
  • the film 2 or 3 can rest "at rest” with an understretch section 21 on the underside of the pallet top layer 11 due to the pressure by means of the pressure device 12, the corresponding measure also evident on the bottom layer 22 the pallet is possible, as has been indicated in FIG. 8 with respect to the understretch section 21 'in a dash-dotted line, or in the case of one not on a pallet 10 or the like. supported loading unit immediately below the piece goods stack 1, as is readily apparent to the person skilled in the art.
  • the lifting frame does not of course have to consist of bow-like sections of the type in question (see FIGS. 5 and 6), but can, for example, consist of consist of a closed frame, the individual legs (for the purpose of transverse stretching) are telescopic.
  • the pressing device 12 can be designed in a wide variety of ways and, in particular, does not need to be a component of the reefing device, as is most expedient, but can, as has already been indicated, be realized, for example, by the fact that the lifting frame 9 held film 2 or 3 in the negative pressure applied through the through holes 13 are held firmly on the lifting frame, while this is possibly / preferably moved from its pull-over position in the pull-over final phase closer to the piece goods stack 1 and the film 2 or 3 is given the opportunity has to put firmly on the piece goods stack 1 or the pallet 10 or a part thereof, so that the understretch 21 or 21 'can then also be produced in an equivalent manner as in a normal "pressing device".
