Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device suitable therefor according to the preamble of claim 12.
  • packaging methods are known in which the piece goods or the piece goods stack is wrapped with so-called shrink film, which is applied with heat after wrapping and then firmly shrinks onto the piece goods or the relevant one Stack of piece goods creates
  • so-called winding processes are known in which flat film is wrapped around the piece goods to be wrapped
  • so-called hood processes are known in which at least one (possibly also two) film hood (s) is pulled over the stack and then shrinking it.
  • shrink film packaging processes include in that the piece goods wrapped in the shrink film must be subjected to heat for the purpose of shrinking. This not only leads to correspondingly high energy costs, but when exposed to a flame it also means that these processes are unsuitable for flammable goods, such as are widely available in the chemical industry, for example, because of the otherwise associated dangers.
  • a further disadvantage of all shrinking methods is that, due to the required film thicknesses, a relatively high amount of material is required, which leads to relatively high packaging costs, since film material has become very expensive as a petroleum product, particularly since the known energy crises.
  • shrinkage is often perceived as not being very environmentally friendly, since this creates exhaust gases to a not inconsiderable extent, and because the operators are exposed to considerable noise pollution.
  • stretch films instead of the shrink film, which do not require any heat to adhere to the piece goods to be packaged. Rather, it is sufficient if the stretch film material is "stretched" before wrapping the piece goods, which after the wrapping causes the film material to contract again and accordingly - as desired - firmly attaches to the piece goods to be wrapped or packaged.
  • Significant “stretching” is understood to mean considerable stretching to an extent which, after wrapping, leads to sufficiently large forces being generated by the film material which ensure sufficient stack strength in the case of stacked piece goods, without it (also possibly after multiple wrapping of a wrapped packaging unit) for mutual sliding of piece goods and the like. is coming.
  • winding stretching has become known, in which stretch film - similar to winding shrinkage - is wrapped around the piece goods to be wrapped.
  • advantages achieved compared to shrinking winding stretching is also associated with not inconsiderable disadvantages. These are, in particular, that the handling is relatively incomprehensible and time-consuming, and that the film consumption - although less than the shrinking - is still perceived as unsatisfactory for cost reasons, this being caused in particular by the fact that overlaps of adjacent layers are required in each case in the winding stretch.
  • the stack strength is also still unsatisfactory, especially if the piece goods stack is only wrapped "in one direction" (then generally horizontally) with web-like stretch film, since then no significant normal forces are generated between adjacent piece goods layers, which only prevent shifting of piece goods layers due to correspondingly increased friction.
  • the internal vertical forces generated by "diagonal” winding are not sufficient for this.
  • a “vertical” wrap would, however, leave two side surfaces of a general cargo stack free, that is, surfaces that would be difficult to cover with sheet films. A double (horizontal and vertical) wrap is out of the question for cost reasons.
  • EP-OS 0 081 328 has already proposed for hand winding stretching to stretch the web-shaped stretch film material in its longitudinal direction by 55% and the resulting contraction of the film web by 30-25% of its original width by an additional stretching to partially compensate transversely to the longitudinal direction in order to save film material, so that the (film) "loss” resulting from the longitudinal stretching can be reduced from 30-25% to approximately 15%, but manual stretching with a two-dimensionally stretched has become Film proved to be hardly practical, since it is hardly possible to wrap general cargo with a two-dimensionally stretched film.
  • a flat film has to be applied as a cover sheet, and a separate cover sheet feeder with a corresponding work step is required for this.
  • packaged goods packed by stretch wrap are often not adequately weather-resistant, since moisture can often penetrate into the packaging unit at the edges of the film, and that the view of the packaged packaged goods is often imperfect, when it is unwinding into a generally hardly avoidable crease comes.
  • DE-OS 27 06 955 and 31 01 310 have made known devices which are also suitable for wrapping piece goods (stacking) with a stretch film hood, as is expressly mentioned in DE-OS 27 06 955 .
  • General cargo stacks with a stretch film hood first come to an (apparently) satisfactory (because smooth) packaging unit with a film wrapper that seems to take into account the requirements for durability or stack strength on the one hand and the tightness of the wrapper on the other hand, but this occurs particularly with stacked goods which, for example, with cement or the like.
  • the stretch film hood is pulled down after the horizontal transverse stretching out of the state of being gained by the guide bracket and slides under it with a certain amount of friction, so that there is a certain vertical expansion can if the tensile forces are to be greater than the frictional forces, but this does not result in significant longitudinal stretching and thus also does not result in the desired dimensional stability of the wrapped piece of goods stack, in particular if these consist of filled sacks.
  • the present invention is accordingly based on the object of improving the known methods and devices of the type in question while avoiding in particular the disadvantages discussed above and to provide a method and a device suitable and specific for carrying out this method, by means of which packaging units the here The type in question can be created using the advantageous stretch film hoods, which do not lose their dimensional stability even in the case of "problem piece goods" and possibly repeated handling.
  • the drawing shows a device designated by 1 for the automatic or automatic wrapping of piece goods by means of a stretch film hood, more precisely of piece goods stacks 2, which consist of stacked piece goods parts (for example bags filled with bulk goods) and have been formed by means of a palletizing device.
  • Tubular film is unwound from a tubular film supply 3 by means of a pair of drivable rollers 5 as a pull-off device in the direction of arrow 4 and fed to a spreading device 6 which has spreading plates 7 tapering against the direction of travel of the film, so that the tubular film (see FIG. 2) can be pulled apart .
  • the free edge section of the film section drawn off from the tubular film supply 3 is pressed and held against the expansion plates 7 by pressing means 8 in the direction of the arrows 8 '.
  • the spreading device 6 is followed by a reefing device, generally designated 9, which is used for reefing, that is to say for the concertina-shaped folding of the tubular film section 3 'which later forms a hood, over a vertical distance h which is less than the length of the film section 3'.
  • a reefing device generally designated 9, which is used for reefing, that is to say for the concertina-shaped folding of the tubular film section 3 'which later forms a hood, over a vertical distance h which is less than the length of the film section 3'.
  • a welding device 10 (see FIG. 3) for forming a horizontal seam 11 is indicated between the spreading device 6 and the reefing device 9, and between the welding device 10 and the spreading device 6 there is a cutting device 12 for cutting off the film hood which forms after welding Foil section 3 '' (see Fig. 4).
  • the device 1 has a stretch device by means of which the film section 3 'is to be stretched.
  • the stretch device itself consists of two individual devices, on the one hand a device for horizontal stretching and on the other hand a device for vertical stretching, as will be described further below.
  • the reefing device 9 should be added that it has a movable reefing jaw 13 or the like. Containing reefing frame 14 which is vertically movable and forms part of the lifting device. The reefing frame 14 also forms part of the stretching device, as will be explained further below.
  • the process continues Pulled off the film from the tubular film supply 3 and by means of the pressing means 8, 8 which, for example, from suction jaws or the like, but also from clamping jaws or the like. can exist, with simultaneous spreading of the tubular film downwards, so that the pressing means 8, 8 per se form pressing and holding means (for the film) (see FIG. 2).
  • the welding device 10 (see FIGS. 3, 10) then functions to form the seam 11 and the film hood 3 ′′ thus formed can be cut off from the film supply by means of the cutting device 12 (see FIG. 3).
  • the remaining section of the side sections forming the side walls of the film hood 3 ′′ is then reefed (see FIG. 4) until the section forming the bottom 17 of the film hood 3 ′′ runs horizontally (that is to say it is tensioned), as is the case here 4, so that afterwards the reefing units 16 according to FIG. 5 can be pivoted outwards and a transverse stretching can take place in the horizontal direction (see FIG. 5), in which the reefing jaws 13 are moved outwards according to the arrows 18 .
  • the film hood 3 ′′ stretched in the transverse or horizontal direction can be pulled over the piece goods stack 2 (see FIG. 6) by lowering the reefing jaws 13 guided on vertical bars 19 according to the arrows 20.
  • vertical stretching of the film hood 3 '' then takes place, but this can also take place when the film is removed from the film stock.
  • Later stretching has the advantage that the film is not yet stretched in the vertical or longitudinal direction during horizontal stretching and accordingly initially is even easier to handle.
  • the film hood 3 ′′ which is shirred and horizontally stretched in accordance with FIG. 5, is pulled over the (longitudinal) stretch bracket 24 when the piece goods stack 2 is pulled over, when it is stretched in the vertical longitudinal direction according to arrow 25 when the reefing unit 16 is lowered is, with a defined longitudinal stretching by about 12% of the already stretched film.
  • the lowering of the stretch jaws 13 forming part of the lifting device takes place below the pallet 21 on which the stack of packaged goods 2 is arranged, so that the stretch film hood 3 ′′ lies under the pallet with its free edge section or engages under it (see FIG. 7).
  • a flat film can also be applied to protect the piece goods stack 2 from below. According to the left part of FIG. 7, this can be done in such a way that the edge 22 'of the flat film 22 is applied upwards to the piece goods stack or, as shown in the right part of FIG. 7, is brought down to the pallet.
  • the latter is somewhat simpler in terms of work, but the solution shown in the left part of FIG. 7 can in principle also be accomplished without difficulty.
  • tubular film can already be removed from the film supply and fed to the spreading device 6, so that after the stack of packaged goods has been wrapped (FIG. 7), the stack of packaged goods is transported away on a conveyor 23 and the transport of a further stack of piece goods 2, a new wrapping process can begin immediately, so that not only the considerable advantages described above can be achieved with the device and the method according to the invention, but also an extraordinarily high work output.
  • packaging units Due to the defined longitudinal stretching of the film material according to the invention in addition to the transverse stretching, even with relatively heavy and heavily ventilated piece goods, such as sacks filled with cement, packaging units are obtained which, even after being folded several times, still have excellent stacking strength, while also being relatively sensitive General cargo stacks, the general cargo layers of which, for example, consist of bottles on intermediate layers, can be handled in an optimal manner according to the invention, since on the one hand the transverse stretch no longer needs to be made as large as it was previously required in hood stretching processes in order to provide at least reasonably satisfactory packaging units Realize (but the transverse forces generated by the transverse stretch were then usually too large for sensitive piece goods), because because of the longitudinal stretching even after subsequent ventilation, it is still common e piece goods harmless, but sufficiently large normal forces are applied by the film wrapping, which ensure a corresponding increase in the frictional forces, so that there is no longer a mutual displacement of adjacent piece goods positions.
