Definitions

  • the invention relates to the packaging of panels of compressible material. More particularly, it relates to a process for packaging panels of fibrous materials in one or more separate batches, themselves combined into a single assembly.
  • fibrous materials in particular glass fibers
  • fibrous materials are frequently delivered to users in the form of panels or mattresses having substantially the shape of a parallelepiped of relatively large dimensions, since its largest dimensions are often of the order of 100 x 50 cm and that its thickness can vary from 30 to 200 mm and even reach 500 mm.
  • These panels can be coated, on one or more of their faces, with a sheet material and the panels are themselves joined either in bundles of ten elementary panels, assembled by a shrinkable polyethylene sheath or by a sheath of paper, either in rolls which can optionally be packaged themselves in the compressed state by the process described in patent application FR-A-2 460 862 and in the application for first certificate of addition FR-A -2 491 889 attached to this patent application, on behalf of Saint-Gobain industries.
  • the present invention aims to provide a method of packaging panels of a compressible material which meets these conditions, without having the drawbacks of the prior art mentioned above.
  • the Applicant has in fact established that, if the compression is divided into at least two successive elementary compressions of an individual amplitude less than the desired overall compression rate, by maintaining the panels in compression between rigid, planar and parallel elements, it it is possible to achieve very high compression ratios (ratio of the thickness of a mattress before compression to the thickness after compression), of the order of 2 to 4 or even 5, without the panels being conditioned under pressure suffer from compression operations.
  • the package of compressed panels is produced from the first compression by introducing the stack of panels in the compressed state into a tubular sheath, made in particular wrapping paper, the dimensions of which correspond to those of the shrink-wrapped plastic cover.
  • the packages thus obtained are then subjected to the second compression and to assembly as described above, in order to produce the stack of compressed packages.
  • the elementary packages can undergo at least one additional compression followed by an additional retraction of the shrinkable material sheath, before stacking these packages.
  • the Applicant produced such packages by subjecting a stack of six panels to compression at a rate of 1.27, then, after retraction of the heat-shrinkable sheath surrounding them, it carried out additional compression of the resulting package, at a rate of 1.37, followed by additional retraction of the retractable sheath, for example by heating the sides of this sheath when it is made of a heat-shrinkable material.
  • packages thus produced were superimposed to form a stack of six packages which was placed between two rigid plates and compressed at a rate of 2, to then be kept in the compressed position using assembly means to form a single batch.
  • the batch thus produced will itself be then wrapped in a shrinkable plastic envelope which will be subjected to a retraction.
  • At least two identical batches may possibly be stacked on top of each other, united by assembly means and possibly sheathed with an additional cover of shrinkable material.
  • the means of assembling the packages and planar elements partially or totally covering the end faces of the lot will comprise a strapping means such as a plastic strip, so that the assembly constituted by said planar elements and the means strapping maintains the batch of packages in the compressed position and has sufficient resistance to the back pressure exerted by the packages, without deformation of the batch.
  • the flat elements associated with the upper faces of the batch of packages may consist of a simple flat plate and / or several parallel panels, made of wood, cardboard or any other material having sufficient rigidity. This or these planar elements may advantageously have at least two parallel ends of the returns forming flaps, applied against the lateral faces of the stack.
  • the individual lots that constitute such stacks of packages can be moved using forklifts whose forks will pierce the envelope (s) of heat-shrinkable material to pick up the lots by their base, it will be preferable that mechanical means rigid enclosing each batch of packages leave passages for said forks, even when a batch rests on a similar batch.
  • beams forming a stiffener will preferably be applied between each strapping means and the planar element of the corresponding face of the lot.
  • the associated beam may advantageously include a groove to accommodate the strapping means. This can also be made integral, by nailing or by any other means, with the associated beam.
  • each lot may include individual strapping means, the beams associated with the underside of a lot being in this case offset transversely to those associated with the upper side of the lot immediately below.
  • the two batches of objects may also include a common strapping means passing over the beams of the lower face of the batch arranged at the base and over the beams of the upper face of the upper batch, the latter resting by its lower beams on the beams of the upper face of the base lot.
  • the beams in question can also be fixed to a frame so as to form a true handling pallet.
  • means for reinforcing and / or protecting the lot may be provided, for example plates protecting certain vertical faces of the lot, possibly with flaps applied against the adjoining faces, or angles placed along the vertical edges of the lot, or even stiffeners arranged vertically and / or transversely along one or more vertical faces of the batch.
  • the invention is not limited to the packaging process which has just been defined, but it also includes batches of panels of compressible material produced by this process.
  • FIG. 1 illustrates, in principle, the production, in accordance with the method of the invention, of a batch of compressible panels 1.
  • the panels 1 are first stacked vertically according to their thickness (FIG. 1a), to form a stack of height x, equal for example to 600 mm.
  • This stack is then wrapped in a sheath 2 of retractable polyethylene and is compressed at a rate of 1.27, its height thus reduced to a value x 2 equal to 480 mm.
  • the polyethylene sheath 2 is then shrunk by heating, and a package 3 with an ovoid section is thus obtained, the sides of which have a height Y2 less than x 2 and equal, for example, to 360 mm (FIG. 1b).
  • Package 3 is again compressed with a compression ratio of 1.37, which reduces its height to a value x 3 equal to 350 mm, the sheath 2 being again subjected to shrinkage by heating its sides.
  • a package 4 is thus obtained with an ovoid section, the sides of which have a height y 3 of less than x 3 and equal, for example, to 220 mm (FIG. 1c).
  • the packages 4 are finally stacked one on the other, in the direction of their thickness between two rigid flat plates 12 (FIG. 1d) and are again compressed, perpendicular to their large face, along the arrow F i , which has for effect of giving each of the packages the shape of a rectangular parallelepiped 5, similar to the original stack shown in FIG. 1a. but whose height X4 is equal to 220 mm.
  • the compact stacks of packages 5 thus produced are rigidly joined together using assembly means which will be described below, then capped with a shrinkable polyethylene cover, which ensures the protection of the compact batch of panel package thus produced.
  • each package and / or each batch including those arranged at the base or at the top of each stack, do not undergo any deterioration due to the fractional compressions to which they are subjected and that they resume their initial shape without permanent deformation, when the user undoes the batch thus produced and releases the panels of the sheath 2 which encloses the package.
  • a cardboard plate 6 comprising lateral flaps 7 is arranged below the package 5 situated at the base of the stack and a similar plate covers the upper package.
  • Beams 8 forming stiffeners are arranged on the external face of the plates 6 and plastic links 9 serving as strapping means bear on the beams 8 and enclose the package.
  • the assembly thus produced is wrapped in a heat-shrinkable polyethylene sheath, to form a compact package, not very bulky and easily manipulated by a forklift, the gripping members of which can be easily introduced under the package, even when that -this is stacked on a similar packaging, as will be seen below.
  • a reinforcing and protective plate 13 is applied to the lower and upper faces of the package stack and, between this plate 13 and the stiffeners 14, over which the plastic links, not shown, pass, are interposed individual panels 15 of wood or cardboard, provided at their ends with flaps 16.
  • the two lateral faces of the stack of packages over which the plastic ties do not pass are protected by a plate 17 provided with flaps 18, but, between plate 17 and the packages, a reinforcing plate 19 is interposed.
  • Figure 4 in which the members already described in relation to Figure 2 keep the same reference numbers, shows how two batches of objects similar to that of Figure 2 can be stacked and assembled to form a single package, making rest the stiffeners 8 arranged at the base of the upper batch on the stiffeners of the upper face of the batch situated below, and by replacing the individual strapping links of each batch with common links 21, which enclose the entire stack of lots.
  • each individual lot is wrapped in a retractable envelope, and the compact assembly formed by the two superimposed lots can itself be protected by a retractable cover.
  • FIG. 5 illustrates another method of stacking another type of packaging according to the invention.
  • a cardboard plate 22 is applied against the lower face and the upper face of each batch and the stiffeners 23 are secured to a common frame 24, with which they form a sort of pallet, which is applied against the plate 22.
  • Metal strips 25 join the ends of the stiffeners 23 of the upper face and the lower face of each batch of packages 5, the stiffeners 23 and the associated strips 25 thus constituting a means of strapping the batch.
  • the metal strips 25 are simply nailed to the ends of the stiffeners 23.
  • the upper batch rests on the upper frame 24 of the lower batch by its stiffeners 23, which are offset with respect to the upper stiffeners of the lower batch. It will be noted that the stiffeners 23 are also offset in position on their respective frames 24, so that the two stacked lots are perpendicular to each other.
  • the frames 24 of the two lots arranged opposite are joined by joining means, for example by pieces of metal strip 26 nailed at regular intervals to the two frames.
  • stiffeners 27 As seen in Figure 6, it is also possible to practice in stiffeners 27 a groove 28 serving as a housing for the strapping link. It will be noted that, in this variant of the stiffeners, these are integral with a sole 29 by which they come into contact with the packages.
  • vertical stiffeners 30 and / or transverse are provided on the lateral faces of the batch of objects, the vertical edges of which are protected by angles 32.
  • FIGS. 8 and 9 illustrate another embodiment of the method according to which the means for assembling the compact stack 5 of packages shown in FIG. 1d consist of a packing box, in particular a cardboard box 40 with flaps 41 (figure 8).
  • a packing box in particular a cardboard box 40 with flaps 41 (figure 8).
  • the stack 5 of packages, compressed between the two flat and rigid plates 12 is introduced into the box 40 placed on edge and whose flaps 41 are in the open position.
  • the flaps 41 are folded and optionally fixed to one another, so as to constitute a modular batch 42 (FIG. 9) according to the invention.
  • FIG. 9 several of these modular lots 42 are stacked on top of each other to form the packaging 45, supported by the plate 43, itself made for example of a sheet of cardboard provided with stiffeners 44 or wooden or polystyrene studs.
  • the batches 42 are in contact with one another by their faces defined by the folded flaps 41, which implies, according to FIG. 9, that the packages of panels 1 are arranged on edge in the packaging 45 and therefore that said panels rest on their edges.
  • the packaging 45 is assembled by styling it with a polyethylene cover 46, which is brought to a temperature sufficient to cause it to shrink and thereby link the batches 42 to each other. In this case, it is not necessary to encircle the packaging obtained, the manufacture of which is thus made more economical.
