Definitions

  • the invention relates to a method of overpacking a palletized load by means of a cover of stretchable plastic film.
  • a palletized load typically comprises a lower pallet and resting on it several superimposed layers each comprising one or more individual loads or loads.
  • Such elementary burdens or loads can be, for example, bags of materials or blocks of solid materials (brick, concrete blocks, plates or the like) or cardboard boxes filled with a certain container or containers, empty or filled, such as bottles, barrels, and ....
  • Such a palletized load conventionally has a general external shape more or less parallelepiped limited by a horizontal lower face (pallet), a free horizontal upper face (roof) and four vertical lateral faces .
  • the palletized load can have an external shape which is not exactly parallelepipedic but inscribed in a parallelepiped. This can for example be the case with bags which give the vertical lateral faces of the palletized load an accordion shape.
  • the palletized load can be of the "without pallet” type, the pallet being replaced by one (or more) layer (s) of burdens or elementary loads located in the lower extreme part and coming laterally behind the others.
  • Palletized loads overwrapped with covers or stretch plastic film have a width (in the horizontal direction) of between 50 cm and 150 cm, a length (also in the horizontal direction) of between 80 cm and 180 cm and a height (in the direction vertical) between approximately 50 cm and 250 cm.
  • a typical palletized load has a length of 120 cm, a width of 100 cm and a height of 200 cm.
  • the cover once in place on the palletized load covers its horizontal upper face and its vertical side faces up to the pallet (or the false pallet).
  • a stretchable plastic film constituting such a cover can, by stretching, be lengthened significantly even beyond its elastic limit and up to several times the latter. Once stretched, it loses some of the extra stretch given to it by stretching. By being dimensionally blocked before having lost the additional elongation which has been given to it before, it creates forces which are used to ensure the tightening of the palletized load.
  • the stretch film covers used for the overwrapping of palletized loads are, to date, delivered and used in the form of rolls of bellows sheath, flattened.
  • a bellows sheath comprises two large facing walls, joined by their edges by two bellows which are themselves facing, the two middle folds of which are closest to each other and situated towards the inside of the sheath.
  • the two bellows are folded back on themselves, not deployed, and placed between the two large facing walls applied to one another.
  • the sheath can be wound on a spool, the width of which can be understood. between 20 cm and 120 cm.
  • a bellows sheath makes it possible to reduce the width of the flattened sheath coil, with all the advantages of space and handling which result therefrom.
  • a bellows sheath is advantageous in that it allows the introduction, into the bellows and from the outside, of separators promoting the opening of the sheath for its implementation.
  • Such an overpacking of palletized loads by means of covers of stretchable plastic film can be produced in the following manner: the palletized load to be overpacked is brought into a hood intended for the implementation of this overpackaging.
  • a hood includes a frame, a support for one or more coils of flattened bellows sheath, of horizontal axes, located in the lower part and outside the hood.
  • the flat bellows sheath is guided and brought to the upper part of the hooder. It is then directed vertically and downwards in line with the palletized load.
  • the sheath is unwound, pre-opened and then completely opened by deployment of the bellows losing its "flattened” state.
  • pre-opening separators and opening means such as belts or drive fingers of the sheath going away from each other from top to bottom are used.
  • the sheath is threaded on a support trolley then located in the upper middle part of the hood, above the palletized load.
  • This carriage has, in horizontal elevation, a substantially homothetic contour of that, opposite, of the palletized load but at this time of the process smaller than the latter.
  • the carriage comprises, in its four angles, four vertical direction angle supports. These four corner supports are placed inside the open sheath and it came to crease using, by example, motorized rollers carried by the frame and supported on the sheath outside of the latter and in line with the angle supports.
  • This pleating can be qualified as transverse since the successive plies extend in transverse direction relative to the longitudinal direction of the sheath.
  • the folds extend in a horizontal direction relative to the vertical longitudinal direction of the load.
  • This pleating of the sheath has the effect that the size of the pleated sheath in the unwinding direction (axis of the sheath) is very small compared to that of the sheath deployed or unfolded. This makes it possible to store a large length of sheath, in the pleated state, on angle supports of limited and smaller length.
  • the carriage is associated with the means for opening the sheath such as two suction boxes with opposite and horizontal reciprocal movements.
  • the sheath When a suitable length of sheath has been unwound, the sheath is cut transversely and a transverse weld is made in order to close the upper free end of the cover. At this time, the sheath then forming a cover, pleated on the carriage is stretched in the transverse direction. For this purpose, the corner supports are moved horizontally to the outside of the hood. This displacement has an amplitude which on the one hand determines the degree of stretching of the film of the cover and on the other hand causes the angle supports to be located, in vertical direction, outside the palletized load. The carriage is then moved with vertical sliding downwards around the palletized load in the stationary position, up to the pallet or the false pallet.
  • the closed end of the sheath where the transverse weld is located is applied to the horizontal upper face of the palletized load.
  • the folds of the bellows extend vertically parallel to the vertical edges of the palletized load and the transverse weld extends parallel to two edges, notably longitudinal and horizontal of the horizontal upper face.
  • the rest of the sheath is gradually applied to the vertical lateral faces of the palletized load.
  • the movement of the carriage is continued until the sheath is completely on the palletized load and released from the carriage. the carriage can then be slid vertically and upwards and brought back to the upper waiting and starting position.
  • the palletized load with the overwrapped stretch film sheath can then be removed from the hood. A new cycle can then be performed.
  • the technique of overwrapping palletized loads with covers made of stretchable plastic film has certain advantages compared to the different competing technique using heat-shrinkable plastic film. In particular, it makes it possible to dispense with the heat shrinking phase and means. In addition, the palletized load is not subjected to the action of heat shrinking heat.
  • the technique of overpackaging of palletized loads with covers of stretch plastic film as it is currently implemented has a certain number of drawbacks or limitations: the upper part of the cover has several film thicknesses due to the presence of bellows and transverse weld simultaneously. This results in an unsightly character of the sheath; an unsatisfactory size of the bellows at the top; wind protection possible in the two pockets formed by the bellows flattened.
  • the perimeter quantity of film is smaller at the upper part of the cover than in the remaining part below. Combined with the several thicknesses of the upper part already mentioned, this results in an uneven stretch between the upper part of the cover and the lower part remaining, the stretch at the upper part being higher than in the lower part remaining .
  • the sheath is stretched with a drawing rate at least equal to 80%.
  • the stretching of the sheath is distributed in the transverse direction and the sheath is applied to the angle supports while allowing free transverse relative movement.
  • the use of a sheath without bellows makes it possible to avoid the direct or indirect drawbacks which result from the existence of the bellows.
  • the extra thickness is avoided at the top of the cover, the perimeter length of film is the same including in the vicinity of the top, the degree of stretching can be greater which allows better clamping forces of the film on the palletized load therefore better cohesion thereof, the aesthetics of the cover is improved.
  • the invention allows both film savings, overwrapping in the same dimension of increased palletized loads having certain dimensional tolerances. Finally, it allows excellent control of the stretching, therefore of the compressive and cohesion forces of the palletized loads.
  • the invention makes it possible to envisage different variants of implementation, in an automatic, semi-automatic or even manual manner, with or without removal of protruding "horns", with or without reversal of the rise. , with or without lower bead, etc ...
  • the invention relates to the overpacking of a palletized load 1 by means of a cover 2 made of stretched plastic film.
  • palletized loads comprise a plurality of elementary bundles or bundles 3 juxtaposed in layers 4 stacked one on the other and on a lower pallet 5.
  • the pallet 5 is replaced by a false pallet, in the case of a load called "without palette”.
  • the lower layer or layers 4 then have recessed lateral free spaces for the passage of the forks of a transporting carriage.
  • Such a palletized load 1 has a general external parallelepiped shape or included in a parallelepipedic envelope.
  • an upper face 6 generally horizontal, four lateral faces forming two opposite pairs 7a, 7b, and a lower face 8, horizontal, at the location of the pallet 5.
  • the upper face 6 is limited by four edges or two opposite pairs 9a, 9b corresponding to the lateral faces 7a, 7b. These four edges 9a, 9b also define four corners 10 where the upper face 6 and two lateral faces 7a, 7b meet.
  • the lateral faces 7a, 7b define between them four vertical edges 11 adjoining the corners 10.
  • the lower face 8 has a structure derived from that of the upper face 6. It should be understood that the edges and corners 9a, 9b, 10 and 11 are more or less straightforward, sharp or acute or, on the contrary, rounded, depending on the elementary burdens or packages 3.
  • the cover 2 is made from a sheath 12 devoid of bellows (s), originally flattened. Such a half-sheath is shown in Figure 1B slightly deployed for better understanding.
  • a sheath 12 without bellows comprises two main walls 13 opposite and facing one another, joined one at a time. the other by a longitudinal fold 14.
  • Such a sheath without bellows differs from the bellows sheaths of the state of the art shown in FIG. 1A.
  • the main walls have a narrower width (or width) and they have a junction bellows placed inside.
  • the process for overpacking a palletized load by means of a stretched plastic film cover comprises the following steps: We start with a sheath 12 without flattened bellows not stretched. Such a sheath can be wound to form a coil 15.
  • the lower initial free end 16 of the sheath 12 is brought above the palletized load 1, facing the upper face 6, by means, for example, of a guide and deflection roller 17 with a horizontal axis.
  • the sheath 12 is continued to unwind from the reel 15 and the sheath 12 is opened from its end 16.
  • the sheath 12 is thus opened, by its initial free end 16, on angle supports 18 (in particular four in number).
  • These angle supports 18 are, in this situation, directed vertically and upwards. They are in a state called “retracted” as opposed to a state called “stretched” later.
  • the unstretched sheath 12 has a smaller perimeter than the perimeter of the palletized load 1 defined by the lateral faces 7a and 7b. It follows that in the retracted state, the angle supports 18 define a smaller footprint than the footprint opposite the palletized load 1 (see figure 2).
  • the angle supports 18 are carried for this purpose by an appropriate frame.
  • the angle supports 18 are in their upper position above the palletized load 1.
  • the retracted state is that where the angle supports 18 are closest to each other. Their distance is such that the open sheath 12 can be threaded onto the supports 18 without being stretched transversely. Thanks to locking projections placed at the bottom of the angle supports 18 and directed horizontally outwards, the initial free end 16 is blocked while the sheath 12 is unwound from the reel 15 and that an additional quantity of this sheath 12 is accumulated on the angle supports 18. With, if necessary, additional means such as rollers or pleating rollers coming to be applied on the sheath 12, outside of the latter and in line with the angle supports 18, the sheath 12 is pleated transversely on the angle supports 18 (FIG. 2B).
  • the pleating is qualified as "transverse” since the pleats 19 which constitute it extend substantially parallel to the initial free end 16, that is to say orthogonally to the longitudinal direction 20 of the sheath 12.
  • the longitudinal direction 20 is the vertical direction and the folds 19 are placed horizontally.
  • sheath 12 When a sufficient longitudinal length of sheath 12 is unwound, taking into account the height of the palletized load 1 including taking into account either a subsequent stretching of the cover in longitudinal direction 20, or the production of a lower bead of film, the sheath 12 is cut transversely above the folds 19. It then follows on the one hand to form a free upper end portion 21 of the sheath and, on the other hand, a new initial free end 16 intended to be used, later, for another cover.
  • the sheath 12 carried by the angle supports 18 is then stretched in the transverse direction and for this purpose the angle supports 18 are reciprocally moved in the transverse direction (in this case horizontal) to make them pass from the retracted state to a stretched state where these are located, in a vertical direction, outside the palletized load 1 ( Figures 2C and 2D).
  • the importance of the transverse, horizontal sliding of the angle supports 18 determines the degree of transverse stretching of the film, which induces the value of the tightening forces of the cover 2 on the load 1 and therefore the cohesion of the latter.
  • the angle supports 18 are moved transversely over a stroke such that the sheath 12 is stretched with an initial stretch rate at least equal to 80%, which allows the cover 2 once placed on the palletized load 1 to have a residual stretch of at least 30%.
  • This stretching rate and this residual stretching are made possible by the use of a sheath 12 without bellows.
  • the rates of stretching and residual stretching are constant or vary little from the initial free end 16 to the end part. upper 21. Indeed, the perimeter length of the sheath 12 without bellows is substantially the same over its entire longitudinal direction 20.
  • the stretching of the sheath 12 is distributed in a transverse direction over the whole of a cross section of the sheath, in a uniform manner or a distribution is as uniform as possible and for this purpose the sheath 12 is applied to the supports d angle 18 by allowing the free transverse relative movement of the sheath 12 relative to the angle supports 18. For this purpose, this relative movement is carried out without substantial friction of the sheath 12 on the angle supports 18.
  • the cross section of the sheath 12 is produced and, practically simultaneously, the transverse welding of the sheath 12 near and below the cutting line 22 thus produced thus constituting a welding line 23.
  • the sheath 12 is placed on the palletized load 1 with the transverse weld line 23 placed substantially diagonally on the upper face 6.
  • the transverse weld line 23 connecting two diametrically opposite corners 10 of the upper face 6 of the load 1.
  • the stretched sheath 12 is suitably arranged from the outset with respect to the palletized load 1 or a relative rotation of the palletized load 1 / cover 2 is carried out around the longitudinal direction 20 with respect to an initial angular relative position where the weld line 23 is parallel to an edge 9a, 9b, to the final relative position thus angularly offset.
  • the sheath 12 is placed on the palletized load 1 with the transverse weld line 23 placed substantially parallel to an edge 9a or 9b of the upper face 6. And, in this case, the protruding horns 24 on and to the remaining part of the sheath 12.
  • the projecting horns 24 are external but folded down and glued or welded to the sheath, in particular that located either on the upper face 6 (right part of FIG. 4) or that lying on the lateral faces 7a, 7b (left part of FIG. 4). Or we gather and glue or weld the projecting horns 24 ( Figures 5A and 5B). Or the protruding horns 24 are heat-shrunk. In the latter case, the heat-shrinking is very localized and limited to the horns 24 alone, so that it can be implemented by means of a light and energy-saving heating device, without the risk of heating the entire palletized load 1.
  • the cover 2 pleated and stretched with the transverse weld line 23 is turned upside down, the free end 16 initially placed at the bottom and the end part 21 where the transverse weld line 23 initially placed at the top is located (FIG. 9A) being reversed by 180 ° around a horizontal axis and then being located respectively at the top and at the bottom (FIG. 9B ).

  • This can be obtained,
  • the horns 24 are interior.
  • a second variant (FIGS. 4, 6, 7A to 7E and 8), the upper end part of the sheath is grouped together in the form of a central tail 25 which is secured and held together. For example, stapling, ligation or welding of the tail 25 is carried out. In this variant, there is therefore no continuous transverse weld line 23.
  • a transverse section is made using, for example, long and continuous cutting jaws 26 and, at the same time, the cover is taken 2 just below the cutting line 22 thus produced at points or zones 27 spaced along the cutting line 22 (FIGS. 7A to 7C).
  • the cutting jaws 26 being able to be moved apart, the points or zones 27 of gripping between two reciprocal jaws can be brought together (see arrows in FIG. 7D) which makes it possible to group the upper end part 21 along a segment more short than the cutting line 22. While maintaining the upper end part 21 thus, it is possible to bring, just below, the welding jaws 28 which ensures welding on a short welding segment where the cover is pleated in the longitudinal direction. In the variant of FIG. 8, the jaws 28 ensure the clipping and not the welding.
  • a transverse cut and weld is made, not rectilinear and perpendicular to the longitudinal axis of the sheath but curved with a concavity facing the load.
