Description

  The present invention relates to a porous material package and a method of manufacturing the porous material package.

  Heretofore, a plate-like porous material made of glass wool or the like has been used as a heat insulating and sound absorbing material installed on a floor surface, a wall surface, a ceiling surface or the like of a house. Such a porous material is provided as a package configured by compressing a plurality of porous materials stacked one on another in a compression bag in order to improve loading efficiency during transportation and storage. There are cases (see, for example, Patent Document 1).

Patent No. 4361863 gazette

  Even if the packing of the porous material as described above is formed, for example, in a rectangular shape at the time of packing, after a certain time (for example, one day) elapses, the compression bag is expanded and the central portion is expanded and turn into. When the central portion is expanded, it is difficult to stack and store the packages, which may reduce the loading efficiency. In addition, when the central portion swells, the porous material may be crushed in the peripheral portion, which may make the construction after unpacking difficult. On the other hand, if the porous material is compressed excessively in order to suppress the central portion from swelling, the porous material becomes so soft that bending occurs after unpacking, which may make construction difficult.

  An object of this invention is to provide the manufacturing method of the package of the porous material which can maintain the shape at the time of packing, and the package of a porous material.

  In this porous material package, expansion deformation in the thickness direction of the porous material is suppressed by the band-like first holding member provided along the outer surface of the compression body in an annular shape, so that compression is performed. It can control that the central part of the body swells. As a result, it becomes possible to maintain the shape at the time of packing.

  The first holding member may be provided in the compression body so as to expose a portion corresponding to a pair of side portions facing each other in the first direction of the main surface. According to this, it is possible to prevent the porous material from being crushed in the pair of side portions while suppressing the central portion of the compressed body from being expanded by the first holding member.

  It may further include a second holding member provided along the outer surface of the compression body so as to be annular as viewed in a second direction along the main surface and orthogonal to the first direction. According to this, since the expansion deformation in the thickness direction of the porous material is suppressed also by the second holding member, it is possible to effectively suppress the central portion of the compression body from expanding.

  The second holding member may be provided in the compression body so as to expose a portion corresponding to a pair of side portions facing each other in the second direction of the main surface. According to this, it is possible to prevent the porous material from being crushed in the pair of side portions while suppressing the central portion of the compressed body from being expanded by the first holding member.

  The first holding member and the second holding member may overlap each other on the central portion of the main surface. According to this, it is possible to more effectively suppress the central portion of the compression body from being inflated.

  The compression body may have a plurality of porous materials, and the compression receiving member may compress and receive the plurality of porous materials stacked so that the main surfaces thereof face each other. According to this, even when a plurality of porous materials are accommodated in the compression accommodating member, it is possible to maintain the shape at the time of packing.

Can be suppressed. Moreover, since a part of holding | maintenance part is thicker than the remaining part, it can suppress effectively that the center part of a compression body bulges. As a result, it becomes possible to maintain the shape at the time of packing.

  In the method for manufacturing a porous material package according to one aspect of the present invention, a plate-like porous material is placed in a compression containing member, air in the compression containing member is removed, and the porous material is compressed by Forming a compressed body in which the porous material in a compressed state is accommodated in the compression accommodating member, and along the outer surface of the compression body so as to form an annular shape as viewed from one direction along the main surface of the porous material Providing a belt-like holding member.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the same or corresponding elements will be denoted by the same reference symbols, without redundant description.

  As shown in FIGS. 1 and 2, the package 1 includes a compression body 2, a first holding member 3, and a second holding member 4.

The compression body 2 has a plurality of (eight in this example) porous materials 5 and a compression containing member 6 for compressing and containing the porous materials 5. The porous material 5 before compression has, for example, a rectangular plate shape (flat rectangular shape). The porous material 5 is a heat insulating and sound absorbing material, and is a heat insulating and sound absorbing material for a floor installed on a floor surface of a house. The porous material 5 is made of glass wool. The porous material 5 may be made of inorganic fibers such as rock wool other than glass wool, glass fibers, silica fibers, alumina fibers, etc., and polyester fibers, polypropylene fibers, nylon fibers, polylactic acid fibers, cellulose fibers, carbon fibers Etc., or natural fibers such as wool, cotton, silk, hemp or the like, or flexible urethane foam, semi-rigid urethane foam or foamed plastic of melamine foam Good. The density of the porous material 5 before compression is, for example, 10 kg / m ³ or more and 64 kg / m ³ or less, preferably 20 kg / m ³ or more and 36 kg / m ³ or less. The thickness of the porous material 5 before compression is, for example, about 20 to 150 mm. The porous material 5 may be installed on the wall surface or ceiling surface of a house.

  The compression accommodating member 6 is formed in a bag shape, for example, of PE (polyethylene), PP (polypropylene), PVC (polyvinyl chloride), nylon or PET (polyethylene terephthalate). The compression accommodating member 6 compresses the porous material 5 by containing the porous material 5 and removing the internal air (degassing). This degassing is performed, for example, using a suction machine such as a vacuum pump while the inside of the compression containing member 6 is kept airtight. At the time of suction, for example, the suction portion of the suction machine may be introduced from the opening for putting the porous material 5 into the compression housing member 6, or another opening may be formed at any position of the compression housing member 6. The suction unit may be introduced from the opening. These openings may or may not be blocked after the aspiration is complete. The thickness of the compression housing member 6 is, for example, about 5 to 140 μm.

  The compression accommodating member 6 compresses and accommodates a plurality of porous materials 5 stacked so that the main surfaces 5a of each other face each other. The compression body 2 has, for example, a rectangular parallelepiped shape, but irregularities are irregularly formed on the outer surface 2 a of the actual compression body 2 (in particular, the outer surface formed by the lamination of the porous members 5). The compression rate (the ratio of the thickness after compression to the thickness before compression) in the thickness direction in the compression body 2 is, for example, 20% or more and 80% or less, preferably 30% or more and 60% or less. For example, the thickness of the compression body 2 before compression is about 640 mm, and the thickness of the compression body 2 after compression is about 200 mm.

  The first holding member 3 is in the form of a strip, and is provided along the outer surface 2 a of the compression body 2 so as to form a rectangular ring when viewed from the first direction D 1 along the major surface 5 a of the porous material 5. The first direction D1 is an arbitrary one direction along the major surface 5a, and is, for example, a direction orthogonal to the pair of side portions 5b and 5b of the major surface 5a. The first holding member 3 covers the four faces of the compression body 2 and has a shape in which the parts covering the faces are connected to each other. In other words, the first holding member 3 covers the compression body 2 continuously along the circumferential direction. The circumferential length of the first holding member 3 is, for example, slightly longer than the circumferential length along the first holding member 3 in the compression body 2 immediately after compression. Thereby, the first holding member 3 holds (restrains) the compression body 2.

  The first holding member 3 may be, for example, a resin film made of a synthetic resin such as PET, PE, PP or PVC, or a paper, a non-woven fabric or a fiber sheet made of inorganic fibers or organic fibers. It may be. The first holding member 3 may be formed with a hole, a tear, a dotted line or a broken line in order to facilitate unpacking. The first holding member 3 is configured, for example, by winding a resin film formed in a band shape around the outer surface 2 a of the compression body 2 a plurality of times (for example, 10 times). The first holding member 3 has, for example, a tensile strength of 1 MPa to 5000 MPa (when the first holding member 3 is composed of non-stretched nylon, 20000 MPa or less), and an elongation of 10% to 1000%. There is.

  The first holding member 3 is provided in the compression body 2 so as to expose the first portions 2b corresponding to the pair of side portions 5b, 5b opposed to each other in the first direction D1 of the main surface 5a. More specifically, the first holding member 3 covers a region including the central portion C (portion on the central portion of the main surface 5a) in a plan view of the compression body 2, while the pair of side portions 5b in the compression body 2 , 5b are exposed (not covered). In this example, the pair of side portions 3a and 3a opposed to each other in the first direction D1 of the first holding member 3 are parallel to each other and parallel to the pair of side portions 5b and 5b. The width along the first direction D1 of the first holding member 3 is greater than 0.05 times and less than 1 time the width along the first direction D1 of the compressed body 2. The first portion 2b described above is a region between the side 3a and the side 5b. In addition, the first holding member 3 exposes a pair of side surfaces facing each other in the first direction D1 of the compression body 2.

  The second holding member 4 has a strip shape, and is formed on the outer surface 2a of the compression body 2 so as to form a rectangular ring when viewed from the second direction D2 along the major surface 5a of the porous material 5 and orthogonal to the first direction D1. It is provided along. The second direction D2 is, for example, a direction orthogonal to the pair of side portions 5c, 5c of the main surface 5a. The pair of side portions 5c, 5c is orthogonal to the pair of side portions 5b, 5b. The second holding member 4 intersects the first holding member 3 through the outer side (opposite to the compression body 2) with respect to the first holding member 3. The second holding member 4 covers the four faces of the compression body 2 and has a shape in which the parts covering the faces are connected to each other. In other words, the second holding member 4 covers the compression body 2 continuously along the circumferential direction. The circumferential length of the second holding member 4 is, for example, slightly longer than the circumferential length along the second holding member 4 in the compression body 2 immediately after compression. Thus, the second holding member 4 holds (restrains) the compression body 2.

  The second holding member 4 may be, for example, a resin film made of a synthetic resin such as PET, PE, PP or PVC, or a paper, a non-woven fabric or a fiber sheet made of inorganic fibers or organic fibers. It may be. The second holding member 4 may be formed with a hole, a tear, a dotted line or a broken line in order to facilitate unpacking. The second holding member 4 is configured, for example, by winding a resin film formed in a band shape around the outer surface 2 a of the compression body 2 a plurality of times (for example, 10 times). The second holding member 4 has, for example, a tensile strength of 1 MPa to 5000 MPa (when the second holding member 4 is made of non-stretched nylon, 20000 MPa or less), and an elongation of 10% to 1000%. There is.

  The second holding member 4 is provided in the compression body 2 so as to expose the second portions 2c corresponding to the pair of side portions 5c, 5c facing each other in the second direction D2 of the main surface 5a. More specifically, the second holding member 4 covers the region including the central portion C of the compression body 2 and exposes the second portion 2 c along the pair of side portions 5 c of the compression body 2. In this example, the pair of side portions 4a, 4a opposed to each other in the second direction D2 of the second holding member 4 are parallel to each other, and are parallel to the pair of side portions 5c, 5c. The width along the second direction D2 of the second holding member 4 is greater than 0.05 times and less than 1 time the width along the second direction D2 of the compressed body 2. The second portion 2c described above is a region between the side 4a and the side 5c. Further, the second holding member 4 exposes a pair of side surfaces facing each other in the second direction D2 of the compression body 2.

  The first holding member 3 and the second holding member 4 overlap each other on the central portion (on the central portion C of the compression body 2) of the main surface 5a. In this example, the overlapping region of the first holding member 3 and the second holding member 4 has a rectangular shape. In addition, the first holding member 3 exposes the first portion 2b of the compression body 2 and the second holding member 4 exposes the second portion 2c of the compression body 2 so that four corners 2d of the compression body 2 are obtained. Are exposed from the first holding member 3 and the second holding member 4.

  Then, the manufacturing method of the package 1 is demonstrated, referring FIG. The following steps are performed manually or by machine. First, as shown in FIG. 3A, the porous material 5 before compression is put into the compression accommodating member 6 from the opening. Subsequently, as described above, the porous material 5 in a compressed state is accommodated in the compression accommodation member 6 by degassing the inside of the compression accommodation member 6 using the suction device to compress the porous material 5. The compact 2 is formed. In this example, the compression accommodating member 6 has an opening 6a (a mouth of the bag-like compression accommodating member 6), and a suction machine is introduced from the opening 6a.

  Subsequently, as shown in FIG. 3B, the first holding member 3 is provided along the outer surface 2a of the compression body 2 so as to have an annular shape as viewed from the first direction D1. Subsequently, along the outer surface 2a of the compression body 2 so as to form an annular shape as viewed from the second direction D2 and to cross the first holding member 3 through the outside with respect to the first holding member 3 A holding member 4 is provided. Thereby, the package 1 shown by FIG. 1 is obtained.

  In the package 1 described above, in the thickness direction of the porous material 5 by the strip-shaped first holding member 3 provided along the outer surface 2 a of the compression body 2 so as to form an annular shape as viewed from the first direction D1. Since the expansion deformation of the body 2 is suppressed, it is possible to suppress the central portion C of the compression body 2 from expanding. As a result, it is possible to maintain the shape at the time of packing.

  That is, when the first holding member 3 and the second holding member 4 are not provided as in the packing body 101 of the comparative example shown in FIG. 4, the packing body 101 is formed, for example, in a rectangular shape at the time of packing. Also, after a certain amount of time (for example, one day) has passed, the compression accommodating member 106 is expanded, and the central portion becomes a bulging shape (drum-like shape).

If the central portion is expanded, it is difficult to stack and store the packages 101, which may reduce the loading efficiency. In addition, when the central portion swells, the porous material 105 may be crushed in the peripheral portion, which may make it difficult to perform the construction after unpacking. Furthermore, the stacked porous materials 105 may be rubbed and twisted at the central portion, which may make the construction after unpacking difficult. On the other hand, if the porous material 105 is compressed excessively in order to suppress the central portion from swelling, the porous material 102 becomes so soft that bending may occur after unpacking, which may make construction difficult. For example, when the density of the porous material 105 after compression becomes about 110 kg / m ³ , construction after unpacking becomes difficult. On the other hand, in the package 1, as described above, the central portion C of the compression body 2 can be prevented from expanding, and the shape at the time of packaging can be maintained, so these problems can be solved. .

  Further, in the packing body 1, the first holding member 3 is provided in the compression body 2 so as to expose the first portions 2b corresponding to the pair of side portions 5b, 5b facing each other in the first direction D1. . Thereby, it is possible to prevent the porous material 5 from being crushed in the pair of side portions 5b, 5b while suppressing the central portion C of the compressed body 2 from being expanded by the first holding member 3.

  Further, in the package 1, a second holding member 4 having an annular shape as viewed in the second direction D <b> 2 is provided along the outer surface 2 a of the compression body 2. Thereby, also by the second holding member 4, expansion deformation in the thickness direction of the porous material 5 is suppressed, so that the central portion C of the compression body 2 can be effectively suppressed from expanding.

  Further, in the package 1, the second holding member 4 is provided in the compression body 2 so as to expose the second portions 2c corresponding to the pair of side portions 5c, 5c opposed to each other in the second direction D2. . Thereby, it is possible to prevent the porous material 5 from being crushed in the pair of side portions 5c, 5c while suppressing the central portion C of the compressed body 2 from being expanded by the first holding member 3.

  Moreover, in the package 1, the 1st holding member 3 and the 2nd holding member 4 mutually overlap on the center part of the main surface 5a. Thereby, the central portion C of the compression body 2 can be more effectively suppressed from being inflated.

  Moreover, in the package 1, the compression accommodating member 6 compresses and accommodates the plurality of porous materials 5 stacked so that the main surfaces 5a of each other face each other. In the package 1, even when the plurality of porous members 5 are accommodated in the compression accommodation member 6 in this manner, it is possible to maintain the shape at the time of packing.

  As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment. For example, as in the package 1A of the first modification shown in FIGS. 5 (a) and 5 (b), even if the second holding member 4 is replaced with a second holding member 4A in the form of a bag, Good. In the package 1A, the compression body 2 held by the first holding member 3 is accommodated in a bag-shaped second holding member 4A having an opening 7 opened on one side in the second direction D2. The compression body 2 is accommodated in the second holding member 4A from the opening 7 by being relatively moved along the second direction D2. The second holding member 4A has a rectangular annular shape when viewed from one side of the second direction D2. The second holding member 4 </ b> A covers the entire outer surface 2 a of the compression body 2. In this example, the second holding member 4A is formed in a gusset shape having a gore, but may be formed in a tube shape without a gore.

  According to such a first modification, as in the above embodiment, the central portion C of the compression body 2 can be prevented from expanding, and the shape at the time of packing can be maintained. Moreover, since the expansion deformation in the thickness direction of the porous material 5 is also suppressed by the second holding member 4A, it is possible to effectively suppress the central portion C of the compression body 2 from being expanded. Further, since the entire outer surface 2a of the compression body 2 is covered by the second holding member 4A, it can be avoided that the corner 2d of the compression body 2 is exposed to the outside, and wear and the like of the corner 2d can be suppressed. Thus, the second holding member 4 (the second holding member 4A) may have an annular shape as viewed from at least one side of the second direction D2. The same applies to the first holding member 3 in this respect.

  The package 1 may be configured like the package 1B of the second modification shown in FIG. 6 (a) or the package 1C of the third modification shown in FIG. 6 (b). In the package 1 </ b> B, a pair of first holding members 3 is provided so as to face each other at an interval in the first direction D <b> 1. The pair of first holding members 3 oppose each other across the central portion C of the compression body 2. In the package 1C, in the package 1B, a pair of second holding members 4 is provided so as to face each other at an interval in the second direction D2. The pair of second holding members 4 oppose each other across the central portion C of the compression body 2. According to the second and third modified examples as described above, as in the above embodiment, the central portion C of the compression body 2 can be prevented from expanding, and the shape at the time of packing can be maintained.

  A holding member 8 may be provided instead of the first holding member 3 and the second holding member 4 as in the package 1D of the fourth modified example shown in FIG. 7. The holding member 8 has a strip-like holding portion 8a provided along the outer surface 2a of the compression body 2 so as to form a rectangular ring when viewed from the first direction D1. In this example, the holding portion 8 a constitutes the entire holding member 8. The holding member 8 is a resin film annularly formed of, for example, PP, PE, PET, or PVC. The holding portion 8 a is provided to expose the first portion 2 b of the compression body 2. The pair of side portions 8b and 8b facing each other in the first direction D1 of the holding portion 8a is parallel to each other and is parallel to the pair of side portions 5b and 5b.

  The portion 8c of the holding portion 8a is thicker than the remaining portion 8d of the holding portion 8a. The portion 8c is, for example, a rectangular region extending along the first direction D1 between the pair of side portions 8b and 8b. The portion 8 c covers a region including the central portion C of the compression body 2. Although only a part 8c provided on one side in the thickness direction of the compressed body 2 is shown in FIG. 6, a part 8c is similarly provided on the other side in the thickness direction. The holding member 8 having such a holding portion 8a is formed, for example, by extrusion molding that extrudes the molten resin along the first direction D1.

  According to such a fourth modification, as in the above embodiment, the central portion C of the compression body 2 can be prevented from expanding, and the shape at the time of packing can be maintained. Further, since the portion 8c of the holding portion 8a is thicker than the remaining portion 8d, it is possible to effectively suppress the central portion C of the compressed body 2 from expanding. In addition, in package 1D, the holding member 8 may be formed in the bag shape which has an opening part opened to one side of 1st direction D1. The holding member 8 may have a portion other than the holding portion 8a. In the holding portion 8a, the thick portion 8c may be formed at an arbitrary position.

  In the above embodiment, in the first holding member 3, the resin film formed in a band shape is not wound around the compression body 2 to form an annular shape, but is previously formed in an annular shape (annular shape or band shape) to be a compression body 2 may be attached. The first holding member 3 may be a stretch film or a heat shrink film. The first holding member 3 may be provided so as to protrude from the compression body 2 so that the pair of side portions 3a, 3a is positioned outside the pair of side portions 5b, 5b. In this case, the width of the portion protruding from the compression body 2 may be equal to or less than the thickness of the compression body 2, for example. The above points also apply to the second holding member 4.

In the above-mentioned embodiment or each modification, porous material 5 may be a porous material with a non-woven fabric. For example, a non-woven fabric may be attached to one of the main surfaces of the porous material 5 by an adhesive. In this case, in the compressed body 2, for example, the non-woven fabric is positioned between the porous members 5. The non-woven fabric is made of, for example, PET, but may be made of organic fibers such as polyester resin and olefin resin. The basis weight (area density) of the non-woven fabric is, for example, 10 g / m ² or more and 80 g / m ² or less, preferably 20 g / m ² or more and 50 g / m ² or less. The basis weight of the non-woven fabric is, for example, 30 g / m ² . The non-woven fabric may or may not be subjected to hydrophilic treatment.

  In the above embodiment or each modification, the first holding member 3 may be fixed to the outer surface 2 a of the compression body 2 by adhesion. In this case, the first holding member 3 is made of, for example, a resin film with an adhesive tape. An adhesive tape is comprised, for example with a base material and the adhesive layer formed on the base material. The substrate is made of, for example, PET, nylon, PP, PE or OPP (biaxially oriented polypropylene). The substrate may be formed in a single layer or in multiple layers (i.e., may be a laminate in which a plurality of layers are laminated). The thickness of the substrate is, for example, 10 μm or more and 140 μm or less, preferably 20 μm or more and 50 μm or less. The adhesive layer is made of, for example, an acrylic, rubber, urethane or silicon adhesive. The thickness of the adhesive layer is, for example, 5 μm or more and 20 μm or less. When the first holding member 3 is fixed to the outer surface 2 a of the compression body 2 by adhesion, the compressed state is easily maintained even when the first holding member 3 is broken and a part of the first holding member 3 is peeled off. Become. Moreover, when the compression body 2 is large, it becomes difficult to wind the band-shaped first holding member 3, but when the first holding member 3 is fixed by adhesion, the first holding member 3 is partially adhered and sequentially fixed By doing this, packing work can be easily performed. Instead of or in addition to the first holding member 3 being fixed to the outer surface 2 a of the compression body 2 by adhesion, after the first holding member 3 is wound around the outer surface 2 a of the compression body 2, the first holding member 3 may be fixed by adhesion of an adhesion layer, and, thereby, the 1st holding member 3 may be fixed to the compression body 2. Similarly, the second holding member 4 may be fixed to the outer surface 2 a of the compression body 2 by adhesion. In this case, the second holding member 4 also adheres to the first holding member 3. Further, both of the first holding member 3 and the second holding member 4 may be fixed to the outer surface 2a by adhesion, or only one of them may be fixed to the outer surface 2a by adhesion. That is, at least one of the first holding member 3 and the second holding member 4 may be fixed to the outer surface 2 a by adhesion.

  In the above embodiment or each modification, the first holding member 3 may be fixed to the outer surface 2 a of the compression body 2 by fusion bonding. In this case, the first holding member 3 includes, for example, a base made of PET, and a fusion layer made of PE and laminated on the base. For example, after the first holding member 3 is wound around the outer surface 2 a of the compression body 2, the first holding member 3 and the outer surface 2 a can be fused (thermally fused) by heating the fusion layer. When the first holding member 3 is fixed to the outer surface 2a of the compression body 2 by fusion bonding, the compressed state is maintained even when the first holding member 3 is broken and a part of the first holding member 3 is peeled off. It will be easier. Moreover, when the compression body 2 is large, it becomes difficult to wind the band-shaped first holding member 3, but when fixing the first holding member 3 by fusion, for example, the first holding member 3 is partially fused By sequentially fixing them, the packing work can be easily performed. Further, since the fusion work can be easily automated, the packing work can be automated to save labor. Instead of or in addition to fixing the first holding member 3 to the outer surface 2 a of the compression body 2 by fusion bonding, after the first holding member 3 is wound around the outer surface 2 a of the compression body 2, the first holding The members 3 may be fixed by the fusion of the fusion layer, whereby the first holding member 3 may be fixed to the compression body 2. Similarly, the second holding member 4 may be fixed to the outer surface 2 a of the compression body 2 by fusion bonding. In this case, the second holding member 4 is also fused to the first holding member 3.
