Definitions
- the present invention relates to the packaging of compressible insulating products, especially for their transport or storage. More specifically, the invention relates to a module comprising compressible insulating products in the unitary state in the form of rolls or substantially parallelepiped batches of panels. The invention also relates to a method of manufacturing such a module, and to a palletized assembly comprising such modules.
- Fibrous insulation products such as glass wool or other mineral wool felts, are low density products that occupy a large volume. In order to facilitate their transport and their storage, it is desirable to limit the bulk of these products and to realize palletising loads.
- the insulating products in the unitary state are conventionally packaged in a compressed state, being coated with a protective envelope generally made of kraft paper or plastic material, the insulating products then being assembled in the form of rows and then positioned on pallets.
- a constraint for the packaging is that the deformations generated during compression of the insulating product should not degrade its ability to take up thickness at deconditioning, the insulating qualities of the product being dependent on this thickness recovery.
- the compression must be adapted so that the deformations it generates develop regularly inside the insulating product, in order to avoid deterioration thereof.
- To this constraint is added the need to protect the insulating product vis-à-vis the external environment, particularly when it comprises a binder sensitive to the effects of moisture.
- the protective envelope for maintaining the product in the form of a roll, or to collect in a batch a series of panels does not generally cover the entire external surface of the product and is therefore not sufficient to ensure complete protection against moisture.
- EP0220980A1 discloses a package in which a module is formed by juxtaposing several insulating products in a row, and belting the row using a film that keeps the insulation products in compression against each other. Several modules are then superimposed on a pallet and the assembly is assembled by wrapping.
- a disadvantage of this type of packaging is that, due to the compression exerted by the strapping film, the modules have a diabolo shape that is not optimal for palletizing.
- the insulation products are protected by the wrapping film, they are no longer protected, particularly at their ends, once the palletized assembly has been opened or damaged. There is a risk of water infiltration into the insulating product, which can lead to degradation of its insulating properties.
- WO2004103821A1 discloses a pack of rolls of compressible fibrous material, in which a plurality of rollers are arranged next to one another with their parallel axes, in several superimposed rows.
- a film wraps each row of several rollers in a compressed state of the rolls, and a sleeve wraps several rows of rollers superimposed in a compressed state of the rows against each other.
- the sleeve covers at least a portion of the peripheral surface of the rollers of an upper row and a lower row of said superposed rows of the pack.
- Such an arrangement does not make it possible to guarantee optimum protection of the insulating products, in particular with respect to moisture, since it is difficult to obtain a homogeneous and continuous wrap, particularly because of differences in lengths or offsets between the rows.
- the invention more particularly intends to remedy by proposing a module of compressible insulating products whose dimensions are stable and reproducible, allowing a compact stack of several modules, in which an improved protection of the insulating products is ensured and the quality of insulating products is preserved, particularly in terms of thickness recovery.
- the subject of the invention is a module comprising compressible insulating products, each insulating product having a longitudinal axis, a peripheral surface and first and second ends, the module comprising: a single row of insulating products arranged next to each other, successively in a first direction perpendicular to the longitudinal axes of the insulating products, the insulating products of the row having their longitudinal axes parallel to each other,
- the module further comprises a third film which envelops the single row of insulating products by covering the first and second ends of each insulating product of the row, so that the single row of insulating products is completely covered by the combination of films.
- the insulating products may be rolls.
- the insulating products may be batches of several previously assembled panels, for example by means of a heat-shrinkable film, these batches having a substantially parallelepiped shape and being of a size close to that of the rollers.
- the module comprises a single row (ie a single row) of insulating products, which is enveloped by both the second film covering a portion of the peripheral surface of the insulating products of the single row and by the third film covering the first and second ends of each insulating product of the single row, means that the second and third films are directly opposite the faces of the single row, without interposition of other row of insulating products located on either side of the single row in a direction perpendicular to the longitudinal axes of the insulating products and in the first direction of the single row.
- the single row of insulating products is completely covered by the combination of the first, second and third films, so that the insulation products of the module are protected from moisture or other contaminants. It is thus possible to very simply realize palletized sets of rolls or panels, by superposition of several modules according to the invention, while ensuring that the insulation products in each module are protected, in particular moisture, even in case of opening or damage of the external protection of the palletized assembly, which may be a wrapping film or a stretch or retractable cover.
- the insulating products comprise a binder which is sensitive to moisture, such as a bio-sourced binder, in particular based on saccharides, sugars and / or sugar alcohols.
- Such palletized assemblies can be stored outside, without any more precaution, without risk of deterioration of the quality of the insulating products and in particular without problem of recovery of thickness.
- the wrap with the second and third films is made for a single row of insulating products, which has several advantages over the case where each row is wrapped with a second film and then a stack of several rows is wrapped with a third film as in WO2004103821A1.
- this double wrap at each row improves the protection of the insulating products especially with respect to moisture because the establishment of a third film overlapping with a second film is easier around a single row rather than around a stack of several rows.
- a stack of rows may comprise non-aligned rows, for example because of differences in lengths or offsets between the rows, which does not allow to have a junction between the films as continuous as in the case of a single row.
- the number of impacted insulating products is lower in the case where each row is wrapped with the third film with respect to the case where a stack of several rows is wrapped with the third film.
- the double wrapping at each row it is possible to unpack only part of a palletized assembly and leave the remaining modules in storage, since for each module the row of insulating products is individually protected from the humidity, not a stack of rows.
- the term "wrap" does not mean that there is a recovery of the entire element that is wrapped.
- the first film may cover the peripheral surface of the insulating product without covering the ends of the insulating product.
- the third film may cover the first and second ends of each insulating product of the row, without covering all the faces of the row which are perpendicular to the ends of the insulating products.
- the second film can cover only a central portion of the peripheral surface of the insulating products of the row, without extending from one end to the other of the insulating products.
- the second film and the third film form, around the single row of insulating products, two sleeves of axes perpendicular to each other. More specifically, the second film forms a sleeve having a central axis extending along the direction of the longitudinal axes of the insulating products, while the third film forms a sleeve whose central axis extends in the first direction.
- the row of insulating products comprises two end faces formed by the ends of the insulating products, as well as two main faces and two transverse faces perpendicular to the ends of the insulating products.
- the second film wraps the single row of insulators extending over the main faces and the transverse faces of the row, without necessarily completely covering the main faces and the transverse faces of the row, while the third film envelops the single row. insulating products extending over the end faces and the main faces of the row, again without necessarily completely cover the main faces of the row.
- the single row of insulating products is completely covered by the combination of the second film and the third film.
- Such an arrangement where a single row is enclosed within a package formed by the combination of the second film and the third film limits the junction areas between films and further improve the protection of the insulation products of the module .
- the third film at least partially covers the second film, or vice versa. This makes it possible to limit the presence of openings or interstices at the interface between the films of the module, which may constitute water entry points inside the module.
- the second film envelopes the single row of insulating products in a compressed state of the insulating products against each other in the first direction.
- This compression in the first direction comes in addition to the compression of each insulating product provided by the first film and limits the size of the module.
- the third film envelops the single row of insulating products in a compressed state of the insulating products in a second direction perpendicular to the longitudinal axes of the insulating products and in the first direction.
- this compression in the second direction comes in addition to the compression of the insulating products against each other in the first direction provided by the second film.
- Compression of insulating products in two perpendicular directions of the module achieves maximum compactness of the module, which corresponds in particular to a substantially parallelepiped shape of the row of insulating products. Thanks to this substantially parallelepipedal shape, the second film and the third film of the module extend along substantially flat surfaces, resulting in a more continuous overlap between the films which guarantee a high level of protection, in particular against water infiltration. inside the module. In addition, the double compression distributes the compression forces, which limits the risk of deterioration of insulation products.
- each insulating product has a square section rounded at the corners.
- a square section rounded at the angles results from the compression of insulating products according to the first direction and in the second direction of the module perpendicular to each other.
- the module has a substantially parallelepiped shape which is very favorable for palletizing.
- the deformations generated in the product are evenly distributed inside the product. This preserves the thickness recovery capacity of the insulation product to deconditioning, and thus its insulation properties.
- the wrapping of a single row of insulating products with the second and third films makes it possible to better control the distribution of the deformations generated in the insulating product, by controlling row by row the compression applied in the first direction and according to the second direction, which is not possible in the case of wrapping each row with a second film and then wrapping a stack of several rows with a third film as described in WO2004103821 A1.
- the second film and the third film are not linked together.
- the second film and the third film may be bonded together, for example by gluing or welding.
- the single row of the module advantageously comprises a number of insulating products between 2 and 10.
- At least one of the first film, the second film and the third film is a plastic film having relatively low extension properties.
- at least one of the first film, the second film and the third film preferably has a stress at 10% elongation greater than 15 MPa, preferably greater than 17 MPa or 20 MPa, in the direction of extrusion and in the direction transverse to the extrusion direction.
- the stress can be measured according to the ISO 527/3 standard, on standard test specimens of film. According to this standard, the elongation of the film is measured for an increasing traction force applied to the film (measured in MPa) and a normalized speed.
- each insulating product and the compression of the row of insulating products can thus be obtained and maintained, respectively, by a first single film, and by second and third single films.
- the first film, the second film and / or the third film are of high density polyethylene (HDPE, or HDPE in English for high density polyethylene).
- the invention also relates to a stack of modules comprising at least two modules as described above, which are superposed in a second direction perpendicular to the longitudinal axes of the insulating products and the first direction of each module.
- Another object of the invention is a palletized assembly comprising a pallet, at least two stacks of modules as described above, which are superimposed on one another and on the pallet with the longitudinal axes of the perpendicular insulating products. to the pallet, and means for holding the stacks on the pallet.
- the means for holding the stacks on the pallet comprise an outer cover.
- the outer cover is a stretch cover, formed by drawing at the periphery of the stacks of a stretchable plastic film sheath, for example a low-density polyethylene (LDPE) sheath.
- the outer cover is a retractable cover, formed by retraction at the periphery of the stacks of a sheath of heat-shrinkable plastic film, for example a heat-shrinkable polyethylene sheath.
- the means for holding the stacks on the pallet comprise a wrapped film at the periphery of the stacks, for example a polyethylene film 20 to 30 microns thick having a mechanical drawing capacity greater than 200 %, in particular of the order of 250%.
- a cap is also provided on the top of the charge formed by the stacks, for example a relatively thick polyethylene film, at least 75 microns thick.
- Another object of the invention is a method of manufacturing a module having a single row of compressible insulating products, each insulating product having a longitudinal axis, a peripheral surface and first and second ends, the method comprising steps in which : each insulating product is enveloped by means of a first film which covers the peripheral surface of the insulating product and which keeps the insulating product in a compressed state;
- the single row of insulating products of the module is formed by placing several insulating products provided with the first film next to one another successively in a first direction perpendicular to the longitudinal axes of the insulating products, the insulating products of the row having their longitudinal axes. parallel to each other;

- the palletized assembly 17 according to the second embodiment differs from the first embodiment in that the maintenance of the stacks 8 on the pallet 13 is not ensured by means of an outer cover 9, but by wrapping with the using a film 10 which is deployed around the stacks 8 and the pallet 13 with a displacement in a direction parallel to the longitudinal axes Xi of the rollers.
- the placing of the wrapping film 10 around the stacks 8 and the pallet 13 is in particular carried out, in a known manner, in a wrapping device.
- the vertical direction of the wrapping device corresponds to the direction of the central axis X10 of the wrapping.
- the wrapping device can be, for example, a rotating ring machine, comprising a unwinding and stretching system of the film 10 and a system for placing a cap 1 1 on the top of the load.
- the wrapping film 10 may be a polyethylene film 20 to 30 microns thick, having a stretching capacity of 250%, and the cap 11 may be based on a polyethylene film. relatively thick, at least 75 microns thick.
- the wrapping operations are carried out in a suitable manner to provide protection against bad weather to the palletized assembly 17.
- the outermost layer of wrapping film 10 is deployed from bottom to top, from so that the uppermost layer is always overlapped from above, with an arrangement similar to roof tiles, as shown schematically in FIG. 8. Such an arrangement prevents water from entering Inside the palletized assembly 17.
- the numbers of revolutions and the percentages of recovery during wrapping are adjusted on a case by case basis.
- a wrapping cycle takes place in the following manner: when the assembly comprising the stacks 8 arranged on the pallet 13 is in place in the wrapping device, a stabilizing plate is lowered to come block the load formed by the stacks 8, and the wrapping starts from below, with a few turns that trap the pallet 13. From below, the The ring is progressively reassembled, a station being made at the junction between the two stacks 8 of the load. When approaching the top of the load, the stabilizing plate is erased, which is possible because the load is self-stabilized by the film already in place. A length of cap film 1 1 is then unwound, at the desired length above the load, the tray is lowered and the cap is cut.
- the invention is not limited to the examples described and shown.
- the values given in the examples above for the dimensions of the rolls and stacks are purely illustrative, it being understood that the dimensions of the stacks according to the invention can be adapted, in particular to be compatible with all dimensions of pallets and stacks. means of transport.
- the invention has been described on the basis of examples involving rolls as insulating products.
- the invention is also applicable to other elongated insulating products, such as batches of panels previously assembled, having a substantially parallelepiped shape.
- the invention can be implemented with materials of the first, second and third films different from those described above.
