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 together either in bundles of ten elementary panels, assembled by a shrinkable polyethylene sheath or by a sheath of paper, or in rolls which can optionally be packaged themselves in the compressed state by the process described in patent application FR 79 17771 of July 9, 1979 and in the request for the first addition certificate FR 80 21735 of October 10, 1980 attached to this patent application, in the name of SAINT-GOBAIN INDUSTRIES.
- the present invention aims to propose 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 keeping the panels in compression between rigid, flat 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 shrinkage of the shrink tubing, for example by heating the sides of this shroud 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 is subjected tra 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 a stack 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 (Figure la), to form a stack of equal height x 1 for example at 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 y 2 less than x 2 and equal, for example, to 360 mm (FIG. 1 b).
- 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).
- Packages 4 are finally stacked on top of each other, in the direction of their thickness between two rigid flat plates 12 (FIG. Id) and are again compressed, perpendicular to their large face, according to arrow F I , which has for effect of giving each package the shape of a rectangular parallelepiped 5, similar to the original stack shown in Figure la, but whose height x 4 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 having side flaps 7 is disposed below the package 5 located 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 sheath of heat-shrinkable polyethylene, to form a compact package, not very bulky and easily manipulated by a fork carriage, 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 quée against the lower face and the upper face of each batch and the stiffeners 23 are integral with a common frame 24, with which they form a sort of pallet, which is applied against the plate 22.
- Metal strips 25 joining the ends of the stiffeners 23 of the upper face and the lower face of each batch of package 5, the stiffeners 23 and the strips 25 associated 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. Id consist of a packing case, in particular a cardboard case 40 with flaps 41 (figure 8).
- a packing case in particular a cardboard case 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 possibly 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 studs in wood or polystyrene.
- 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.

Description
L'invention concerne le conditionnement de panneaux d'un matériau compressible. Elle a plus particulièrement pour objet un procédé pour conditionner en un ou plusieurs lots distincts, eux-mêmes réunis en un unique ensemble, des panneaux de matériaux fibreux.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.
C'est à cette application que l'on se référera dans la suite de la présente description, mais il apparaîtra clairement à l'homme de l'art que le procédé conforme à l'invention s'applique aussi bien à toute matière compressible autre que les matières fibreuses.It is to this application that reference will be made in the remainder of this description, but it will be clear to those skilled in the art that the process according to the invention applies equally to any compressible material other than fibrous materials.
On sait que les matières fibreuses, notamment les fibres de verre, sont féquemment livrées aux utilisateurs sous forme de panneaux ou matelas ayant sensiblement la forme d'un parallélépipède de dimensions relativement importantes, puisque ses plus grandes dimensions sont souvent de l'ordre de 100 X 50 cm et que son épaisseur peut varier de 30 à 200 mm et même atteindre 500 mm. Ces panneaux peuvent être revêtus, sur une ou plusieurs de leurs faces, d'un matériau en feuille et les panneaux sont eux-mêmes réunis soit en ballots d'une dizaine de panneaux élémentaires, assemblés par une gaine de polyéthylène rétractable ou par une gaine de papier, soit en rouleaux que l'on peut éventuellement eux-mêmes conditionner à l'état comprimé par le procédé décrit dans la demande de brevet FR 79 17771 du 9 juillet 1979 et dans la demande de premier certificat d'addition FR 80 21735 du 10 octobre 1980 rattachée à cette demande de brevet, au nom de SAINT-GOBAIN INDUSTRIES.It is known that fibrous materials, in particular glass fibers, 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 together either in bundles of ten elementary panels, assembled by a shrinkable polyethylene sheath or by a sheath of paper, or in rolls which can optionally be packaged themselves in the compressed state by the process described in patent application FR 79 17771 of July 9, 1979 and in the request for the first addition certificate FR 80 21735 of October 10, 1980 attached to this patent application, in the name of SAINT-GOBAIN INDUSTRIES.
Par ailleurs, on connaît, d'après le brevet belge 866 144, un procédé d'emballage de panneaux compressibles, suivant lequel on procède à des compressions partielles de lots de panneaux superposés que l'on introduit dans une enveloppe d'emballage.Furthermore, from Belgian patent 866,144, a method of packaging compressible panels is known, according to which partial compressions of batches of superimposed panels are carried out which are introduced into a packaging envelope.
La livraison aux utilisateurs des panneaux sous forme de simples ballots conduit cependant à une détérioration des panneaux ainsi conditionnés, et, lorsque l'on ouvre le ballot, les panneaux ont perdu leurs propriétés initiales, ce qui est évidemment très nuisible à l'usage du produit.The delivery to the users of the panels in the form of simple bundles however leads to a deterioration of the panels thus conditioned, and, when the bundle is opened, the panels have lost their initial properties, which is obviously very harmful to the use of the product.
Il est cependant important, aussi bien en vue du stockage par le fabricant ou l'utilisateur, que pour les opérations de manutention ou de transport, que les panneaux soient conditionnés sous un volume aussi faible que possible, ce qui implique une compression importante de ces panneaux, dans une mesure compatible toutefois avec une reprise de forme satisfaisante, lorsque cesse la compression, et sans détérioration de leurs propriétés mécaniques.It is however important, both for storage by the manufacturer or the user, and for handling or transport operations, that the panels be packaged in as small a volume as possible, which implies a significant compression of these panels, to an extent compatible however with a satisfactory return to shape, when compression stops, and without deterioration of their mechanical properties.
La présente invention vise à proposer un procédé de conditionnement -de panneaux d'un matériau compressible qui réponde à ces conditions, sans présenter les inconvénients de la technique antérieure rappelés ci-dessus.The present invention aims to propose a method of packaging panels of a compressible material which meets these conditions, without having the drawbacks of the prior art mentioned above.
La demanderesse a en effet établi que, si l'on fractionne la compression en au moins deux compressions élémentaires successives d'une amplitude individuelle inférieure au taux de compression global désiré, en maintenant en compression les panneaux entre des éléments rigides, plans et parallèles il est possible d'atteindre des taux de compression (rapport de l'épaisseur d'un matelas avant compression à l'épaisseur après compression) très importants, de l'ordre de 2 à 4, voire 5, sans que les panneaux conditionnés sous pression souffrent des opérations de compression.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 keeping the panels in compression between rigid, flat 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.
L'invention a par conséquent pour objet un procédé de conditionnement de panneaux compressibles caractérisé par les opérations successives suivantes :
- - on superpose, verticalement ou horizontalement, suivant leur épaisseur, une pluralité de panneaux ;
- - on gaine la pile ainsi réalisée d'au moins une housse de matière plastique rétractable ;
- - on soumet à une première compression, perpendiculairement aux grandes faces de panneaux, la pile de panneaux ainsi gainée ;
- - on provoque la rétraction de la housse sur la pile comprimée pour obtenir un colis de panneaux comprimés ;
- - on superpose suivant leur épaisseur, éventuellement suivant plusieurs piles contiguës, une pluralité de colis identiques de panneaux comprimés ;
- - on applique contre chacune des faces d'extrémité de la pile de colis ainsi réalisée un élément rigide plan ;
- - on soumet à une seconde compression, perpendiculairement aux dits éléments plans, ladite pile de colis ;
- - et l'on réunit en un unique lot, à l'aide de moyens d'assemblage, la pile de colis ainsi comprimés.
- - A plurality of panels are superimposed, vertically or horizontally, depending on their thickness;
- - The stack thus produced is sheathed with at least one shrinkable plastic cover;
- - Is subjected to a first compression, perpendicular to the large faces of panels, the stack of panels thus sheathed;
- - It causes the shrinkage of the cover on the compressed stack to obtain a package of compressed panels;
- - A plurality of identical packages of compressed panels are superimposed according to their thickness, possibly along several adjoining stacks;
- - A flat rigid element is applied against each of the end faces of the stack of packages thus produced;
- - Is subjected to a second compression, perpendicular to said planar elements, said stack of packages;
- - And we gather in a single batch, using assembly means, the stack of packages thus compressed.
Selon une variante du procédé particulièrement économique et qui s'applique bien au conditionnement de panneaux aisément compressibles, on réalise le colis de panneaux comprimés issu de la première compression en introduisant la pile de panneaux à l'état comprimé dans une gaine tubulaire, faite notamment de papier d'emballage, et dont les dimensions correspondent à celles de la housse de matière plastique ayant subi la rétraction. On soumet ensuite les colis ainsi obtenus à la seconde compression et à l'assemblage comme décrit ci-dessus, pour réaliser la pile de colis comprimés.According to a variant of the particularly economical process which applies well to the packaging of easily compressible panels, 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.
Eventuellement les colis élémentaires pourront subir au moins une compression additionnelle suivie d'une rétraction complémentaire de la gaine de matière rétractable, avant d'empiler ces colis.Optionally, the elementary packages can undergo at least one additional compression followed by an additional retraction of the shrinkable material sheath, before stacking these packages.
C'est ainsi que la Demanderesse a réalisé de tels colis en soumettant à une compression d'un taux de 1,27 un empilement de six panneaux, puis, après rétraction de la gaine thermorétractable les entourant, elle a procédé à une compression additionnelle du colis résultant, à un taux de 1,37, suivie d'une rétraction additionnelle de la gaine rétractable, par exemple par chauffage des flancs de cette gaine lorsqu'elle est en une matière thermorêtractable.Thus, 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 shrinkage of the shrink tubing, for example by heating the sides of this shroud when it is made of a heat-shrinkable material.
Enfin, les colis ainsi réalisés ont été superposés pour former une pile de six colis qui a été disposée entre deux plaques rigides et comprimée à un taux de 2, pour être ensuite maintenus en position comprimée à l'aide de moyens d'assemblage pour former un unique lot.Finally, the 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.
De préférence, le lot ainsi réalisé sera lui-même gainé ensuite d'une enveloppe en matière plastique rétractable que l'on soumettra à une rétraction.Preferably, the batch thus produced will itself be then wrapped in a shrinkable plastic envelope which is subjected tra to a retraction.
Au moins deux lots identiques pourront être éventuellement gerbés les uns sur les autres, réunis par des moyens d'assemblage et éventuellement gainés d'une housse additionnelle de matière rétractable.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.
Les moyens d'assemblage des colis et des éléments plans recouvrant partiellement ou totalement les faces d'extrémité du lot comprendront un moyen de cerclage tel qu'un feuillard de matière plastique, de façon que l'ensemble constitué par lesdits éléments plans et les moyens de cerclage maintienne le lot de colis en position comprimée et présente une résistance suffisante à la contre-pression exercée par les colis, sans déformation du lot. Les éléments plans associés aux faces supérieures du lot de colis pourront être constitués par une simple plaque plane et/ou par plusieurs panneaux parallèles, en bois, en carton ou en tout autre matériau présentant une rigidité suffisante. Ce ou ces éléments plans pourront avantageusement avoir à au moins deux extrémités parallèles des retours formant rabats, appliqués contre les faces latérales de la pile.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.
Pour que les lots individuels que constituent de tels empilement de colis puissent être déplacés à l'aide de chariots à fourche dont les fourches perceront la ou les enveloppes de matière thermorétractable pour venir saisir les lots par leur base, il sera préférable que les moyens mécaniques rigides enserrant chaque lot de colis laissent subsister des passages pour lesdites fourches, même lorsqu'un lot repose sur un lot analogue. A cet effet, des poutres formant raidisseur seront de préférence appliquées entre chaque moyen de cerclage et l'élément plan de la face correspondante du lot. Pour éviter tout déplacement du moyen de cerclage au cours des manutentions, la poutre associée pourra avantageusement comporter une gorge pour loger le moyen de cerclage. Celui-ci pourra aussi être rendu solidaire, par clouage ou par tout autre moyen, de la poutre associée. Dans le cas d'au moins deux lots analogues gerbés les uns sur les autres, chaque lot pourra comporter des moyens de cerclage individuels, les poutres associées à la face inférieure d'un lot étant dans ce cas décalées transversalement par rapport à celles associées à la face supérieure du lot immédiatement inférieur. Les deux lots d'objets pourront également comporter un moyen de cerclage commun passant sur les poutres de la face inférieure du lot disposé à la base et sur les poutres de la face supérieure du lot supérieur, ce dernier reposant par ses poutres inférieures sur les poutres de la face supérieure du lot de base.So that the individual lots that constitute such a stack 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. For this purpose, beams forming a stiffener will preferably be applied between each strapping means and the planar element of the corresponding face of the lot. To avoid any displacement of the strapping means during handling, 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. In the case of at least two similar lots stacked on top of each other, 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.
Les poutres en question pourront d'ailleurs être fixées à un cadre de façon à former une véritable palette de manutention.The beams in question can also be fixed to a frame so as to form a true handling pallet.
Bien entendu, des moyens de renfort et/ou de protection du lot pourront être prévus, par exemple des plaques protégeant certaines faces verticales du lot, éventuellement avec des rabats appliqués contre les faces attenantes, ou des cornières disposées suivant les arêtes verticales du lot, ou encore des raidisseurs disposés verticalement et/ou transversalement suivant une ou plusieurs faces verticales du lot.Of course, 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.
Bien entendu, l'invention n'est pas limitée au procédé de conditionnement qui vient d'être défini, mais elle englobe également les lots de panneaux de matière compressible réalisés par ce procédé.Of course, 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.

On se référera d'abord à la figure 1, qui illustre, dans son principe, la réalisation, conformément au procédé de l'invention, d'un lot de panneaux compressibles 1.Reference will first be made to FIG. 1, which illustrates, in principle, the production, in accordance with the method of the invention, of a batch of
Les panneaux 1 sont d'abord empilés verticalement suivant leur épaisseur (figure la), pour former une pile de hauteur x1 égale par exemple à 600 mm.The
Cette pile est ensuite enveloppée d'une gaine 2 de polyéthylène rétractable et est comprimée à un taux de 1,27, sa hauteur ainsi ramenée à une valeur x2 égale à 480 mm. La gaine 2 de polyéthylène est ensuite rétractée par chauffage, et l'on obtient ainsi un colis 3 à section ovoide, dont les flancs ont une hauteur y2 inférieure à x2 et égale, par exemple, à 360 mm (figure lb).This stack is then wrapped in a
Le colis 3 est à nouveau comprimé avec un taux de compression de 1,37, ce qui ramène sa hauteur à une valeur x3 égale à 350 mm, la gaine 2 étant à nouveau soumise à une rétraction par chauffage de ses flancs. On obtient ainsi un colis 4 à section ovoïde, dont les flancs ont une hauteur y3 inférieure à x3 et égale, par exemple, à 220 mm (figure 1c).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
Les colis 4 sont enfin empilés les uns sur les autres, dans le sens de leur épaisseur entre deux plaques plans rigides 12 (figure Id) et sont à nouveau comprimés, perpendiculairement à leur grande face, suivant la flèche FI, ce qui a pour effet de redonner à chacun des colis la forme d'un parallélépipède rectangle 5, analogue à la pile d'origine représentée sur la figure la, mais dont la hauteur x4 est égale à 220 mm.Packages 4 are finally stacked on top of each other, in the direction of their thickness between two rigid flat plates 12 (FIG. Id) and are again compressed, perpendicular to their large face, according to arrow F I , which has for effect of giving each package the shape of a
Ensuite, ou simultanément, les piles compactes de colis 5 ainsi réalisées sont réunies rigidement à l'aide de moyens d'assemblage qui seront décrits ci-après, puis coiffées d'une housse de polyéthylène rétractable, qui assure la protection du lot compact de colis de panneaux ainsi réalisé.Then, or simultaneously, the compact stacks of
Il est à noter que les panneaux de chaque colis et/ou de chaque lot, y compris ceux disposés à la base ou au sommet de chaque pile, ne subissent aucune détérioration du fait des compressions fractionnées auxquelles ils sont soumis et qu'ils reprennent leur forme initiale sans déformation permanente, lorsque l'utilisateur défait le lot ainsi réalisé et libère les panneaux de la gaine 2 qui enserre le colis.It should be noted that the panels of 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
Ainsi qu'il a été indiqué ci-dessus, de nombreux moyens d'assemblage des colis 5 à l'état comprimé et des plaques 12 (figure Id) peuvent être utilisés dans le cadre de l'invention. Dans les types de lots de colis qui seront décrits ci-après et qui n'ont aucun caractère limitatif, ces moyens d'assemblage sont en outre tels qu'ils permettent le gerbage de deux plusieurs lots analogues sans, pour autant, s'opposer à la manutention des lots par des chariots à fourche.As indicated above, numerous means for assembling the
Dans le cas de la figure 2, une plaque de carton 6 comportant des rabats latéraux 7 est disposée au-dessous du colis 5 situé à la base de la pile et une plaque analogue coiffe le colis supérieur. Des poutres 8 formant raidisseurs sont disposées sur la face externe des plaques 6 et des liens de plastique 9 servant de moyens de cerclage prennent appui sur les poutres 8 et enserrent le colis. Des plaques de carton 10, munies de rabats 11, coiffent les deux faces latérales parallèles de la pile de colis sur lesquelles ne passent pas les liens 9 et servent de protection pour ces faces. Enfin, l'assemblage ainsi réalisé est enveloppé d'une gaine de polyéthylène thermorétractable, pour former un conditionnement compact, peu volumineux et aisément manipulable par un chariot à fourche, dont les organes de préhension peuvent être facilement introduits sous le conditionnement, même lorsque celui-ci est gerbé sur un conditionnement analogue, comme on le verra ci-après.In the case of Figure 2, a
Dans la variante de la figure 3, une plaque de renfort et de protection 13 est appliquée sur les faces inférieure et supérieure de la pile de colis et, entre cette plaque 13 et les raidisseurs 14, sur lesquels passent les liens de plastique non représentés, sont interposés des panneaux individuels 15 en bois ou en carton, munis à leurs extrémités de rabats 16. Comme dans le cas de la figure 2, les deux faces latérales de la pile de colis sur lesquelles ne passent pas les liens plastiques sont protégées par une plaque 17 munie de rabats 18, mais, entre la plaque 17 et les colis, est interposée une plaque de renfort 19.In the variant of FIG. 3, a reinforcing and
La figure 4, sur laquelle les organes déjà décrits en relation avec la figure 2 conservent les mêmes chiffres de référence, montre comment deux lots d'objets analogues à celui de la figure 2 peuvent être gerbés et assemblés pour former un conditionnement unique, en faisant reposer les raidisseurs 8 disposés à la base du lot supérieur sur les raidisseurs de la face supérieure du lot situé au-desdsous, et en substituant aux liens individuels de cerclage de chaque lot des liens communs 21, qui enserrent l'ensemble de la pile de lots. Comme précédemment, chaque lot individuel est gainé d'une enveloppe rétractable, et l'ensemble compact formé par les deux lots superposés peut être lui-même protégé par une housse rétractable.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
La figure 5 illustre un autre mode de gerbage d'un autre type de conditionnement conforme à l'invention.FIG. 5 illustrates another method of stacking another type of packaging according to the invention.
Dans ce conditionnement, une plaque de carton 22 est appliquée contre la face inférieure et la face supérieure de chaque lot et les raidisseurs 23 sont solidaires d'un cadre commun 24, avec lequel ils forment une sorte de palette, qui est appliquée contre la plaque 22. Des feuillards métalliques 25 réunissant les extrémités des raidisseurs 23 de la face supérieure et de la face inférieure de chaque lot de colis 5, les raidisseurs 23 et les feuillards 25 associés constituant ainsi un moyen de cerclage du lot. Les feuillards métalliques 25 sont simplement cloués aux extrémités des raidisseurs 23.In this packaging, a
Le lot supérieur repose sur le cadre supérieur 24 du lot inférieur par ses raidisseurs 23, qui sont décalés par rapport aux raidisseurs supérieurs du lot inférieur. On notera que les raidisseurs 23 sont aussi décalés en position sur leurs cadres respectifs 24, de manière que les deux lots gerbés soient à l'aplomb l'un de l'autre. Les cadres 24 des deux lots disposés en regard sont réunis par des moyens de jonction, par exemple par des morceaux de feuillard métallique 26 cloués à intervalle régulier sur les deux cadres.The upper batch rests on the
Comme on le voit sur la figure 6, il est également possible de pratiquer dans des raidisseurs 27 une rainure 28 servant de logement pour le lien de cerclage. On notera que, dans cette variante des raidisseurs, ceux-ci sont solidaires d'une semelle 29 par laquelle ils viennent en contact avec les colis.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.
Dans la forme de mise en oeuvre de l'invention illustrée par la figure 7, des raidisseurs verticaux 30 et/ou transversaux sont prévus sur les faces latérales du lot d'objets, dont les arêtes verticales sont protégées par des cornières 32.In the embodiment of the invention illustrated in FIG. 7,
Les figures 8 et 9 illustrent un autre mode de réalisation du procédé selon lequel les moyens d'assemblage de la pile compacte 5 de colis représentée à la figure Id sont constitués par une caisse d'emballage, notamment une caisse de carton 40 à rabats 41 (figure 8). Comme illustré par cette figure, la pile 5 de colis, comprimée entre les deux plaques planes et rigides 12, est introduite dans la caisse 40 placée de chant et dont les rabats 41 sont en position ouverte. Après la mise en place de la pile 5 dans le carton 40, on replie et fixe éventuellement les rabats 41 les uns aux autres, de façon à constituer un lot modulaire 42 (figure 9) conforme à l'invention.FIGS. 8 and 9 illustrate another embodiment of the method according to which the means for assembling the
Comme représenté à la figure 9, plusieurs de ces lots modulaires 42 sont empilés les uns sur les autres pour constituer le conditionnement 45, supporté par le plateau 43, lui-même constitué par exemple d'une feuille de carton munie de raidisseurs 44 ou de plots en bois ou en polystyrène. On remarquera que les lots 42 sont en contact les uns avec les autres par leurs faces définies par les rabats 41 repliés, ce qui implique, selon la figure 9, que les colis de panneaux 1 sont disposés de chant dans le conditionnement 45 et par conséquent que lesdits panneaux reposent sur leur tranche.As shown in FIG. 9, several of these
Finalement, l'assemblage du conditionnement 45 est effectué en coiffant celui-ci avec une housse de polyéthylène 46, que l'on porte à une température suffisante pour en provoquer la rétraction et par là lier les lots 42 les uns aux autres. Il n'est pas nécessaire dans ce cas de cercler le conditionnement obtenu, dont la fabrication est ainsi rendue plus économique.Finally, the
Parmi les avantages que procure le mode de réalisation illustré par les figures 8 et 9, on peut citer :
- - la construction du conditionnement 45 est rendue indépendante de la composition du remplissage des lots modulaires 42,
- - la cote de la hauteur du conditionnement 45 est très régulière et elle peut être tenue à 2 cm près, ce qui facilite l'introduction dudit conditionnement dans les véhicules couverts,
- - les arêtes des lots modulaires 42 résistent bien à l'empilement et les contraintes imposées à l'emballage pour le maintien des feutres 1 en compression n'existent pas dans la direction de l'empilement des
lots 42, ce qui a pour effet, dans le cas d'un rela- chement de cette compression du à la détérioration accidentelle d'un ou plusieurs lots modulaires 42, d'éviter d'affecter la hauteur du conditionnement 45 dans sa constance et par là de conserver la faculté d'extraire facilement celui-ci du véhicule couvert.
- the construction of the
packaging 45 is made independent of the composition of the filling of themodular lots 42, - the dimension of the height of the
package 45 is very regular and it can be kept to within 2 cm, which facilitates the introduction of said package in the covered vehicles, - the edges of the
modular batches 42 resist the stacking well and the constraints imposed on the packaging for maintaining thefelts 1 in compression do not exist in the direction of the stacking of thebatches 42, which has the effect, in the case of a relaxation of this compression due to the accidental deterioration of one or moremodular batches 42, to avoid affecting the height of thepackaging 45 in its constancy and thereby to retain the ability to extract easily this one from the covered vehicle.
D'autres modifications peuvent être apportées au procédé de conditionnement qui vient d'être décrit et aux lots de panneaux compressibles réalisés par ce procédé sans sortir du cadre de l'invention.Other modifications can be made to the packaging process which has just been described and to the batches of compressible panels produced by this process without departing from the scope of the invention.
