Description

[Technical Field]

[0001] The present invention relates to a technique for manufacturing a laminate made up of a plurality of plate materials including glass plates. [Background technology]

[0002] As is well known, in the manufacturing process of a laminate (including laminated glass) consisting of multiple plate materials such as glass plates and resin plates, a temporary laminate made by stacking multiple plate materials is placed in a bag, and then the bag is sealed and the inside is evacuated, thereby bonding the multiple plate materials together.

[0003] As a method for manufacturing this type of laminate, Patent Document 1 discloses a method in which a laminate (a temporary laminate) made by sandwiching four thermoplastic resin sheets between two float glass sheets is placed in a resin bag and the opening of the bag is heat-sealed (see paragraph

[0080] of the same document). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 2019 / 058953 Summary of the Invention [Problem to be solved by the invention]

[0005] However, relying solely on heat sealing as a sealing method to obtain a sealed bag as disclosed in Patent Document 1 poses the problem that the sealing operation takes a long time, which leads to a decrease in the efficiency of the operation when obtaining a sealed bag and ultimately to a decrease in the productivity of the laminate.

[0006] From the above viewpoints, the object of the present invention is to improve the work efficiency and, ultimately, the productivity of the laminate by enabling the sealing work to be performed in a short time when obtaining a sealed bag in the process of manufacturing a laminate consisting of multiple plate materials including a glass plate. [Means for solving the problem]

[0007] (1) A first aspect of the present invention, which has been invented to solve the above-mentioned problems, is a method for manufacturing a laminate, comprising: a temporary assembly step of sandwiching a temporary laminate, which is made by stacking multiple plate materials including a glass plate, between a first sheet material and a second sheet material; a sealing step of sealing the first sheet material and the second sheet material along a planned sealing line around the temporary laminate to form a sealed bag; an exhaust step of discharging gas from inside the bag; and a bonding step of bonding the multiple plate materials to each other to create a laminate, at least after the sealing step, wherein the sealing step is characterized by comprising a clamping step of clamping the first sheet material and the second sheet material with a clamping jig to form a clamped portion for at least a portion of the planned sealing line.

[0008] According to this configuration, the sealing process of forming a sealed bag from the first sheet material and the second sheet material (hereinafter referred to as both sheet materials) includes a clamping process of clamping the first sheet material and the second sheet material with a clamping jig to form a clamped portion. Therefore, the time required for the sealing process is reduced compared to when only heat sealing is used as the sealing method. This improves the work efficiency when obtaining a sealed bag and ultimately improves the productivity of the laminate.

[0009] (2) In the configuration of (1) above, the clamping jig may include a long receiving member and a long engaging member, the receiving member having a groove portion extending along the long direction of the receiving member, the engaging member having a base portion extending along the long direction of the engaging member, and an engaging portion connected to the base portion, extending along the long direction of the base, and engaging with the groove portion, and in the clamping process, the first sheet material and the second sheet material may be clamped between the groove portion and the engaging portion.

[0010] In this way, the sealing work can be completed simply by sandwiching both sheet materials between the groove portion of the receiving member and the fitting portion of the fitting member that fits into the groove portion, and fitting the groove portion and the fitting portion together, thereby further improving work efficiency and thereby productivity.

[0011] (3) In the above configuration (2), the receiving member may have a plurality of grooves, and the fitting member may have a plurality of fitting portions that fit into the plurality of grooves.

[0012] In this way, the two sheet materials are sandwiched in a plurality of rows, so that the two sheet materials are firmly sandwiched and the bag can be more reliably sealed.

[0013] (4) In the configuration of (2) or (3) above, the receiving member may be a rectangular pillar having a plurality of flat surfaces extending along the longitudinal direction of the receiving member, and the grooves may be provided in two or more of the flat surfaces.

[0014] In this way, grooves are provided on two or more flat surfaces of the rectangular pillar-shaped receiving member, and by making it possible to fit the fitting portions of the fitting members into each of these grooves, it is possible to make the configuration in which both sheet materials are clamped in two or more rows compact.

[0015] (5) In any of the configurations (2) to (4) above, in a cross section perpendicular to the longitudinal direction of the receiving member and the engaging member, the maximum widthwise length of the engaging portion may be longer than the widthwise length of the opening of the groove portion, and at least one of the engaging portion or the groove portion may be elastically deformable.

[0016] In this way, when fitting the fitting portion into the groove portion, at least one of them is elastically deformed to fit, and after fitting, at least one of them returns to its original shape due to its restoring force, making it difficult for the fitting portion to come off the groove portion, so that both sheet materials can be properly clamped.

[0017] (6) In any of the above configurations (2) to (5), the width of the opening of the groove may be shorter than the maximum width of the groove.

[0018] In this way, the fitting portion that has entered the groove portion is effectively prevented from coming off.

[0019] (7) In any of the configurations (2) to (6) above, the fitting portion includes a convex rib portion extending along the longitudinal direction of the fitting member and protruding from a widthwise intermediate portion of the base, and an insert portion provided at a portion on the protruding end side of the convex rib portion, and the maximum widthwise length of the insert portion is longer than the widthwise length of the opening of the groove portion and the widthwise length of the convex rib portion, and in the sealing process, the first sheet material, the second sheet material, and the insert portion pressing the first sheet material and the second sheet material may be pushed into the groove portion through the opening and fitted in a state in which the convex rib portion protrudes from the base toward the bottom side of the groove portion.

[0020] In this way, the insertion portion provided in the fitting portion is less likely to slip out of the opening of the groove portion, and the two sheet materials are properly sandwiched between the insertion portion and the groove portion.

[0021] (8) In the configuration of (7) above, the insertion portion may have an arrowhead shape.

[0022] In this way, due to the shape of the insertion portion, it is easy to insert the insertion portion into the groove portion, making it easy to fit the mating portion into the groove portion and efficiently preventing the mating portion from coming off the groove portion.

[0023] (9) In any of the above configurations (2) to (8), the receiving member may be made of metal, and at least the fitting portion of the fitting member may be made of resin or rubber.

[0024] In this way, the receiving member, which is difficult to deform, and the mating portion of the mating member, which is easily deformed, make it easy to fit the mating portion into the groove portion, and the rigidity of the clamping jig after fitting is increased, thereby preventing undue deformation of the clamping jig when performing the exhaust process.

[0025] (10) In any of the configurations (2) to (9) above, in the clamping process, a roller-shaped pressing portion provided on the pressing jig may be rolled on the base in the longitudinal direction, while applying a pressing force from the roller-shaped pressing portion to the base toward the groove portion, thereby fitting the fitting portion into the groove portion.

[0026] In this way, the roller-shaped pressing portion of the pressing jig rolls along the longitudinal direction on the base of the fitting member, causing the fitting portion to be pushed into the groove portion via the base, thereby improving workability or efficiency when fitting a long fitting portion into a long groove portion.

[0027] (11) In any of the configurations (2) to (10) above, the clamping jig may include a pressing member placed on the base and a clamping mechanism that applies a pressing force to the pressing member toward the groove portion, and in the clamping process, the clamping mechanism may press the fitting portion toward the groove portion via the pressing member and the base, thereby holding the fitting portion fitted into the groove portion.

[0028] In this way, when the fitting portion is fitted into the groove portion, the fitting portion is pressed toward the groove portion by the clamping mechanism, thereby more reliably preventing the fitting portion from coming off the groove portion.

[0029] (12) In any of the configurations (1) to (11) above, the first sheet material may be arranged on the lower side of the temporary laminate, and the second sheet material may be arranged on the upper side of the temporary laminate, and the first sheet material and the second sheet material may be separate members.

[0030] In this way, each step can be performed in a work space equivalent to one sheet of both sheet materials, thereby reducing the work space and improving workability.

[0031] (13) In any of the configurations (1) to (12) above, the sealing step may include a bonding portion forming step of bonding a portion of the intended sealing line to form a bonding portion, and in the clamping step, at least a portion of the intended sealing line other than the bonding portion may be clamped with a clamping jig.

[0032] In this way, it is possible to avoid problems caused by clamping the entire circumference of the planned sealing line with the clamping jig. That is, if the entire planned sealing line is clamped with the clamping jig, wrinkles may form in the bent or curved parts of the clamped part, making it impossible to create a sealed bag. Therefore, in order to make it difficult for wrinkles to form in the clamped part, a part of the planned sealing line is glued and at least the part other than the glued part is clamped with the clamping jig.

[0033] (14) In the above configuration (13), the planned sealing lines are composed of a pair of short planned lines extending in a straight line and arranged parallel to each other, and a pair of long planned lines extending in a straight line and arranged parallel to each other and intersecting the pair of short planned lines at right angles, and a nozzle for discharging gas in the exhaust process is arranged at a position where the short planned lines are present, and in the sealing process, an adhesive portion forming process may be performed for the short planned lines and a clamping process may be performed for the long planned lines.

[0034] In this way, the length of the intended sealing line that is clamped by the clamping jig is longer than the length that is bonded. Therefore, the time required to seal the two sheet materials can be efficiently shortened. Moreover, since the nozzle is located at the position of the intended short line, the problem of the nozzle getting in the way and preventing the clamping process from being performed smoothly can be avoided.

[0035] (15) In the configuration of (13) or (14) above, after the adhesive forming process is completed, a clamping process may be carried out so that the part where the adhesive forming process is carried out and the part where the clamping process is carried out overlap at the intersection of the short planned line and the long planned line.

[0036] In this way, the clamping process is carried out including a portion of the adhesive portion of both sheet materials formed by the adhesive portion forming process, so that all of the short planned lines and long planned lines can be reliably sealed.

[0037] (16) In any of the configurations (1) to (15) above, the sealing step may include a nozzle periphery sealing step in which a nozzle for discharging gas in the exhaust step is disposed between the first sheet material and the second sheet material, and a part of the intended sealing line including the position of the nozzle is sealed with a sealant to form a sealant sealed portion.

[0038] In this way, both sheets of material can be reliably sealed around the nozzle.

[0039] (17) In the configuration of (16) above, the sealing process includes a thermocompression bonding process in which a portion of the intended sealing line is heat-sealed to form a thermocompression bonded portion, and the sealant sealing portion and the thermocompression bonded portion may partially overlap.

[0040] In this way, both sheet materials can be reliably sealed even between the adjacent sealant sealed portions and the thermocompression bonded portions.

[0041] (18) A second aspect of the present invention, which has been invented to solve the above-mentioned problems, is a laminate manufacturing article used to manufacture a laminate, characterized in that it comprises a temporary laminate formed by stacking multiple plate materials including glass plates, a first sheet material and a second sheet material that sandwich the temporary laminate, a clamping jig that clamps the first sheet material and the second sheet material, and an adhesive device that adheres the temporary laminate.

[0042] When a laminate is produced using the article for laminate production having such a configuration, substantially the same effects as those obtained in the case of the configuration (1) above can be obtained. [Effects of the Invention]

[0043] According to the present invention, in the process of manufacturing a laminate consisting of multiple plate materials including glass plates, the sealing work to obtain a sealed bag can be completed in a short time, improving work efficiency and ultimately improving the productivity of the laminate.

DETAILED DESCRIPTION OF THE INVENTION

[0045] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for manufacturing a laminate, an article for manufacturing a laminate, and a vacuum bag according to embodiments of the present invention will be described below with reference to the accompanying drawings.

[0046] The manufacturing method of the laminate according to this embodiment can be broadly divided into a pre-assembly step S1, a sealing step S2, an exhaust step S3, a bonding step S4, a cutting step S5, and a removal step S6, as shown in FIG.

[0047] <Temporary assembly process> In the temporary assembly step S1, first, as shown in Figures 2 and 3, a temporary laminate assembly 3 including a temporary laminate 2 is placed on a first sheet material 1. In this embodiment, two temporary laminate assemblies 3 are placed on the rectangular first sheet material 1 (see Figure 2). The first sheet material 1 is placed on an upper surface 4a of a mounting member 4 such as a setter (see Figure 3).

[0048] As shown in Fig. 3, the temporary laminate assembly 3 is formed by laminating backing plates 6 on both the upper and lower sides of the temporary laminate 2 via release films 5. The temporary laminate 2 is formed by laminating glass plates 9 on both the upper and lower sides of a resin plate 7 via adhesive sheets 8. The backing plates 6, release films 5, glass plates 9, adhesive sheets 8, and resin plates 7 are all rectangular, and are not adhered to one another.

[0049] Next, in the temporary assembly step S1, as shown in FIG. 4, the tops of the first sheet material 1 and the temporary laminated assembly 3 are covered with a second sheet material 10. As a result, the two temporary laminated assemblies 3 are sandwiched between the first sheet material 1 and the second sheet material 10. In the illustrated example, the first sheet material 1 and the second sheet material 10 are the same size, and the two long sides 1a, 10a and the two short sides 1b, 10b of both sheet materials 1, 10 are aligned in the same positions. Note that the sizes of the first sheet material 1 and the second sheet material 10 may be different. In the following description, for convenience, the AA direction (the direction along the long sides 1a, 10a) shown in FIG. 4 will be referred to as the vertical direction, and the BB direction (the direction along the short sides 1b, 10b) shown in the same figure will be referred to as the horizontal direction.

[0050] Both sheet materials 1 and 10 are made of a polyamide synthetic resin such as nylon, and have a thickness of preferably 0.01 to 1.0 mm, more preferably 0.03 to 0.5 mm. The longitudinal length La of both sheet materials 1 and 10 is preferably 1000 to 5000 mm, and the lateral length Lb of both sheet materials 1 and 10 is preferably 500 to 3000 mm.

[0051] Both of the two backing plates 6 may be made of metal, but in this embodiment they are made of glass (for example, soda glass) and preferably have a thickness of 6 to 10 mm. Both of the two release films 5 are made of, for example, a non-adhesive fluororesin and preferably have a thickness of 0.02 to 1.0 mm. Both of the two adhesive sheets 8 are made of, for example, a thermally crosslinkable adhesive or a thermoplastic adhesive and preferably have a thickness of 0.1 to 1.0 mm. The resin plate 7 is made of, for example, a transparent resin such as polycarbonate or acrylic and preferably have a thickness of 0.5 to 15.0 mm. Both of the two glass plates 9 are formed by a downdraw method such as an overflow downdraw method or a float method and preferably have a thickness of 0.1 to 1.0 mm.

[0052] 2, the vertical length Lc of the temporary laminated assembly 3 is preferably 300 to 3000 mm, and the horizontal length Ld is preferably 100 to 2500 mm. In this case, referring to FIG. 3, the sizes (vertical length and horizontal length) of all of the components of the temporary laminated assembly 3, namely, the backing plate 6, the release film 5, the glass plate 9, the adhesive sheet 8, and the resin plate 7, may be the same. However, it is preferable that the sizes increase in the order of the glass plate 9, the resin plate 7, the backing plate 6, the adhesive sheet 8, and the release film 5.

[0053] <Sealing process> The sealing step S2 is a step of sealing both sheet materials 1, 10 along the planned sealing lines M1, M2, M3, and M4 shown by dashed lines in Fig. 5 to form a sealed bag from both sheet materials 1, 10. Here, the planned sealing lines include two long planned lines M1, M2 extending in a straight line along the longitudinal direction on the long sides 1a, 10a of both sheet materials 1, 10, and two short planned lines M3, M4 extending in a straight line along the transverse direction on the short sides 1b, 10b of both sheet materials 1, 10.

[0054] In the illustrated example, the two long-length planned lines M1, M2 each reach one short side 1b, 10b and the other short side 1b, 10b, and the two short-length planned lines M3, M4 each reach one long side 1a, 10a and the other long side 1a, 10a. This need not be the only requirement, as long as the two long-length planned lines M1, M2 and the two short-length planned lines M3, M4 intersect at four corners of both sheet materials 1, 10. In the sealing step S2, the adhesive portion forming step shown in FIG. 1 is performed first, followed by the clamping step shown in the same figure.

[0055] <Sealing process (adhesive part forming process)> First, the adhesive portion forming step of the sealing step S2 will be described. In this adhesive portion forming step, as shown in Fig. 6, a nozzle 11 used in the exhaust step S3 (described in detail later) is sandwiched between the portions of one of the short sides 1b, 10b of both sheet materials 1, 10. A hose 12 is attached to the rear end of the nozzle 11. A tip 11a of the nozzle 11 passes through one of the planned short length lines M3 and protrudes toward one of the temporary laminated assemblies 3. Note that the process of sandwiching the nozzle 11 between both sheet materials 1, 10 here may be performed in the above-mentioned temporary assembling step S1.

[0056] The adhesive portion forming step includes a nozzle periphery sealing step of sealing the periphery of the nozzle 11 on one of the short planned lines M3 with a sealant to form a sealant sealed portion 13 as an adhesive portion, as shown by a solid line in Fig. 7. Furthermore, the adhesive portion forming step includes a thermocompression bonding step of heat-sealing a portion of one of the short planned lines M3 other than the periphery of the nozzle 11 to form a thermocompression bonded portion 14 as an adhesive portion, after the nozzle periphery sealing step, as shown in Fig. 8.

[0057] More specifically, in the nozzle-periphery sealing process, a pair of upper and lower seal members 15 shown in FIG. 9 is used. Each of these seal members 15 has an inner surface 15a and an outer surface 15b as adhesive surfaces. The inner surface 15a of each of these seal members 15 is adhered to the outer peripheral surface 11b of the nozzle 11, and the inner surfaces 15a of these seal members 15 are adhered to each other on both lateral sides of the nozzle 11. Furthermore, the inner surfaces 1c and 10c of both sheet materials 1 and 10 are adhered to the outer surfaces 15b of each of these seal members 15. This forms the sealant-sealed portion 13 described above.

[0058] In the thermocompression bonding process, as shown in Fig. 9, a total of four thermocompression bonding devices 16 are arranged on the outer surfaces 10d of both sheet materials 1, 10 on both sides of the lateral direction around the nozzle 11, and sandwich the two sheet materials 1, 10 to form a thermocompression bonded portion 14 as shown in Fig. 10. This thermocompression bonded portion 14 and the sealant sealed portion 13 overlap at a portion J1 at both lateral ends of the sealant sealed portion 13, as shown in Fig. 8.

[0059] In contrast, for the other short-length planned line M4, a thermocompression bonding device 16 similar to that described above, arranged on the outer surfaces 1d and 10d of both sheet materials 1 and 10, sandwiches both sheet materials 1 and 10 together to form a thermocompression bonded portion 14 along its entire length, as shown in Figure 11.

[0060] <Sealing process (clamping process)> Next, the clamping step of the sealing step S2 will be described. This clamping step is performed after the above-mentioned adhesive portion forming step. In this clamping step, as shown in FIG. 12, clamping jigs 17 clamp two long planned lines M1 and M2 on both sheet materials 1 and 10, respectively, to form clamping portions 18 at two locations on the long sides 1a and 10a of both sheet materials 1 and 10. Both clamping jigs 17 are elongated in the vertical direction. Since both clamping jigs 17 have the same configuration, the following description of the clamping step will refer to only one of the clamping jigs 17.

[0061] 13, the clamping jig 17 includes a receiving member 20 that is long in the vertical direction, and a fitting member 21 that is long in the vertical direction. In this embodiment, the receiving member 20 and the fitting member 21 have the same vertical length, and both vertical end portions of the receiving member 20 and the fitting member 21 and the short sides 1b, 10b of the sheet materials 1, 10 are aligned in the same position (see FIG. 12).

[0062] The receiving member 20 and the fitting member 21 may have different vertical lengths. When these lengths are different, both vertical ends of the receiving member 20 may protrude beyond both vertical ends of the fitting member 21, or conversely, both vertical ends of the fitting member 21 may protrude beyond both vertical ends of the receiving member 20. Furthermore, both vertical ends of the receiving member 20 and the fitting member 21 may protrude beyond one and the other short sides 1b, 10b of both sheet materials 1, 10, or both short sides 1b, 10b of both sheet materials 1, 10 may protrude beyond both vertical ends of the receiving member 20 and the fitting member 21, respectively.

[0063] Fig. 14 is a cross-sectional view perpendicular to the longitudinal direction of the receiving member 20, and Fig. 15 is a cross-sectional view perpendicular to the longitudinal direction of the fitting member 21. In the following description, for convenience, the lateral directions of the receiving member 20 and the fitting member 21 will be referred to as the "width direction."

[0064] As shown in Fig. 14, the receiving member 20 has grooves 22 extending along the longitudinal direction of the receiving member 20. More specifically, as shown in Fig. 14, the receiving member 20 is shaped like a rectangular pillar having a plurality of (four in the illustrated example) flat surfaces 20a extending along the longitudinal direction of the receiving member 20, and grooves 22 are provided on all of the flat surfaces 20a (four flat surfaces 20a in the illustrated example). The receiving member 20 is made of a metal such as an aluminum alloy, carbon steel, or stainless steel, and is substantially not elastically deformable (more specifically, is difficult to elastically deform). From the viewpoint of improving workability during the clamping process, it is preferable that the receiving member 20 be made of a lightweight aluminum alloy.

[0065] Each of these grooves 22 is formed from an opening 22a and a recess 22b that communicates with the opening 22a. Since all of these grooves 22 have the same configuration, the following description will only cover the groove 22 provided in the upper flat surface 20a.

[0066] The opening 22a of the groove 22 is a gap between a pair of flat outer peripheral wall portions 20b. More specifically, the opening 22a is formed between a side surface 22c of one outer peripheral wall portion 20b and the opposing side surface 22c of the other outer peripheral wall portion 20b. The recess 22b has a flat bottom surface 22d and a pair of inclined surfaces 22e (inclined at an angle of 45°) that are continuous with both widthwise ends of the bottom surface 22d and whose widthwise separation length gradually increases toward the opening 22a. Furthermore, the recess 22b has a pair of inner surfaces 22f that extend inward in the width direction from the peripheries of the opening 22a-side ends of the pair of inclined surfaces 22e to the side surfaces 22c of the opening 22a.

[0067] A central wall portion 20c having an angular shape (rectangular in the illustrated example) is formed in the center of the receiving member 20 and is surrounded by a plurality of bottom surfaces 22d (four bottom surfaces in the illustrated example) of the groove portion 22. A hole 20d (circular hole in the illustrated example) for reducing weight is formed in the central wall portion 20c.

[0068] 15, the fitting member 21 includes a base 23 extending along the longitudinal direction of the fitting member 21, and a fitting portion 24 that is continuous with the base 23 and extends along the longitudinal direction of the base 23. The fitting member 21 is made of a resin such as polypropylene or a rubber such as silicone rubber, fluororubber, acrylic rubber, ethylene propylene rubber, or chlorosulfonated polyethylene rubber, and is easily elastically deformed.

[0069] The base 23 is flat. A protrusion 23a protruding to one side is formed at each of both widthwise ends of the base 23. The fitting portion 24 has a ridge 24a protruding to the one side from a widthwise intermediate portion of the base 23 and extending along the longitudinal direction of the base 23. The ridge 24a protrudes to the one side along a straight line perpendicular to the base 23. Furthermore, the fitting portion 24 has an insertion portion 24b continuing from the protruding end of the ridge 24a and extending along the longitudinal direction of the ridge 24a.

[0070] The insertion portion 24b has a generally arrow-shaped configuration. Specifically, the insertion portion 24b includes a flat bottom portion 24c extending from the protruding end of the ridge portion 24a to both sides in the width direction and parallel to the base portion 23. The insertion portion 24b also includes a pair of first inclined portions 24d that are connected to both widthwise ends of the bottom portion 24c and gradually move away from the ridge portion 24a as they move toward the base portion 23. The insertion portion 24b also includes a pair of second inclined portions 24e that are connected to the ends of the pair of first inclined portions 24d on the base portion 23 side and gradually approach the ridge portion 24a as they move toward the base portion 23. The second inclined portions 24e are shorter than the first inclined portions 24d. The insertion portion 24b also includes a pair of tip portions 24f that are connected to the ends of the pair of second inclined portions 24e on the base portion 23 side and extend along a straight line parallel to the ridge portion 24a. The tip portion 24f is shorter than the first inclined portion 24d.

[0071] Here, the lengths of the various parts of the receiving member 20 shown in Fig. 14 and the fitting member 21 shown in Fig. 15 will be compared and explained. The widthwise length L1 of the opening 22a of the groove 22 in the receiving member 20 is shorter than the maximum widthwise length L2 of the fitting portion 24 (insertion portion 24b) in the fitting member 21. The widthwise length L1 of the opening 22a of the groove 22 is shorter than the maximum widthwise length L3 of the groove 22. The maximum widthwise length L2 of the fitting portion 24 (insertion portion 24b) is shorter than the maximum widthwise length L3 of the groove 22.

[0072] 16 illustrates a state in which the fitting portion 24 of the fitting member 21 is fitted into the groove portion 22 of the receiving member 20. In this state, the inner surface 23b of the base portion 23 of the fitting member 21 (the inner surfaces 23b of the pair of protrusions 23a) is in contact with the outer surface 22g of the outer peripheral wall portion 20b of the receiving member 20. Then, the protruding ridge portion 24a of the fitting portion 24 enters the recessed portion 22b of the groove portion 22, so that the bottom portion 24c of the insertion portion 24b is in contact with the bottom surface 22d of the recessed portion 22b of the groove portion 22.

[0073] Due to elastic deformation, the insertion portion 24b has a shorter widthwise separation between a portion including one first inclined portion 24d, one second inclined portion 24e, and one tip end 24f and a portion including the other first inclined portion 24d, the other second inclined portion 24e, and the other tip end 24f. In this elastically deformed state, one tip end 24f of the insertion portion 24b contacts the side surface 22c of one outer peripheral wall portion 20b, and the other tip end 24f of the insertion portion 24b contacts the side surface 22c of the other outer peripheral wall portion 20b. In this state, neither of the pair of tip ends 24f protrudes from the opening 22a. In addition, the boundary portion between one tip 24f of the insertion portion 24b and one second inclined portion 24e contacts the corner portion between the inner surface 22f and side surface 22c of one outer wall portion 20b, and the boundary portion between the other tip 24f of the insertion portion 24b and the other second inclined portion 24e contacts the corner portion between the inner surface 22f and side surface 22c of the other outer wall portion 20b.

[0074] In the clamping process, the sheet materials 1, 10 and the insertion portion 24b that presses the sheet materials 1, 10 are pushed into the recessed portion 22b through the opening 22a of the groove portion 22 and fitted into the recessed portion 22b. During this fitting, the roller-shaped pressing portion 30a of the pressing jig 30 shown in FIG. 12 is rolled along the vertical direction on the base 23, thereby applying a pressing force from the roller-shaped pressing portion 30a to the base 23 toward the groove 22. This pressing force is applied over the entire length of the base 23. As a result, as shown in FIG. 17, the groove 22 of the receiving member 20 and the fitting portion 24 of the fitting member 21 are fitted together while clamping the sheet materials 1, 10. As a result, the sheet materials 1, 10 are firmly clamped by the clamping jig 17.

[0075] More specifically, the sheet materials 1 and 10 are sandwiched between the inner surface 23b of the base 23 of the fitting member 21 (the inner surfaces 23b of the pair of protrusions 23a) and both outer surfaces 22g of the pair of outer peripheral wall portions 20b of the receiving member 20. The sheet materials 1 and 10 are also sandwiched between the pair of tip portions 24f of the insertion portion 24b and both side surfaces 22c of the pair of outer peripheral wall portions 20b. Furthermore, the sheet materials 1 and 10 are sandwiched between the bottom portions 24c of the insertion portion 24b and the bottom surfaces 22d of the recesses 22b of the groove portions 22. By sandwiching the sheet materials 1 and 10 between the various portions of the clamping jig 17 in this manner, the sheet materials 1 and 10 are firmly clamped by the clamping jig 17.

[0076] In the clamping process described above, one of the multiple grooves 22 provided in the receiving member 20 and the fitting portion 24 of one fitting member 21 clamp and fit together the two sheet materials 1, 10, but multiple grooves 22 and the fitting portions 24 of multiple fitting members 21 configured in the same manner as above may also clamp and fit together the two sheet materials 1, 10, respectively.

[0077] As a result of the clamping process, as shown in Fig. 18, in addition to the above-mentioned sealant sealed portions 13 and thermocompression bonded portions 14 already formed on both sheet materials 1 and 10, a clamped portion 18 is formed by being clamped by a pair of clamping jigs 17. In this case, the thermocompression bonded portions 14 and the clamped portion 18 overlap at a portion K1 in the square portions of both sheet materials 1 and 10. As a result, both sheet materials 1 and 10 become a sealed bag. More specifically, the area X surrounded by the sealant sealed portions 13, thermocompression bonded portions 14, and clamped portions 18 on both sheet materials 1 and 10 becomes a sealed bag.

[0078] <Exhaust process> In the exhaust process S3, the pump 31 connected to the hose 12 attached to the nozzle 11 is operated to exhaust gas (air) from inside the sealed sheet materials 1, 10 (the above-mentioned area X). As a result, the temporary laminated assembly 3 is sandwiched and compressed between the sheet materials 1, 10, and the temporary laminated body 2 is also compressed. In other words, the temporary laminated body 2 is subjected to a pressing force by the pair of backing plates 6.

[0079] <Adhesion process> In this embodiment, the bonding step S4 refers to a heating step. The heating step may be performed simultaneously with the evacuation step S3 or after the evacuation step S3 is completed. In the heating step, the compressed temporary laminated assembly 3 is heated from the outside of both sheet materials 1 and 10, thereby thermally melting the adhesive sheet 8 included in the temporary laminated assembly 2. Specifically, as shown in FIG. 19 , the temporary laminated assembly 3 is placed on a mounting member 4, and the mounting members 4 are stacked in multiple layers and placed in a heating device 32 such as an autoclave for heating. This firmly bonds the resin plate 7 and the glass plate 9 together with an adhesive layer made of the molten adhesive sheet 8. As a result, a laminate is obtained in which the glass plates 9 are laminated and integrated onto the top and bottom surfaces of the resin plate 7 via adhesive layers.

[0080] <Cutting process> In the cutting step S5, as shown in Fig. 20, first, the pair of clamping jigs 17 are removed from both sheet materials 1, 10, and then both sheet materials 1, 10 are cut along the cutting line Lx shown by the chain line. This removes the thermocompression-bonded portion 14 over the entire lateral length of one of the sheet materials 1, 10. In this case, the clamping jig 17 is removed by pulling out the fitting portion 24 of the fitting member 21 from the groove portion 22 of the receiving member 20 in the state shown in Fig. 17. During this pulling out, the insertion portion 24b of the fitting portion 24 elastically deforms, which facilitates the removal of the clamping jig 17.

[0081] <Removal process> In the removal step S6, the clamping jig 17 is removed and the thermocompression-bonded portion 14 extending over the entire width of one of the sheet materials 1 and 10 is removed. The second sheet material 10 is then rolled up as shown in FIG. 21 . This exposes the backing plate 6 and the laminate 25, making it easy to remove the laminate 25 (laminate). Specifically, because the laminate 25 is heavy, removing the laminate 25 is difficult unless the space above the laminate 25 is open. However, in the state shown in FIG. 21 , the space above the laminate 25 is open, making it easy to remove the laminate 25. Furthermore, the sheet materials 1 and 10 can be efficiently reused after the laminate 25 is removed. In other words, by lengthening the longitudinal length of the sheet materials 1 and 10 by the amount required to remove the thermocompression-bonded portion 14 extending over the entire width of one of the sheet materials 1 and 10, they can be reused without increasing the lateral length of the sheet materials 1 and 10.

[0082] [First Modification] In the first modified example, the configuration of the fitting member 21 of the clamping jig 17 used in the clamping step included in the sealing step S2 differs from the configuration of the fitting member 21 already described. Only the differences will be explained below. As shown in FIG. 22, the fitting member 21 according to the first modified example has a base 23 to which a block-shaped fitting portion 24 is connected. A cavity 26 is formed in the base 23, and a cavity 27 is also formed in the fitting portion 24. The fitting portion 24 is configured by a ridge portion 24a and an insertion portion 24b connected in series. In this case as well, the insertion portion 24b has a general arrow-like shape.

[0083] The insertion portion 24b has a curved bottom surface 24h and a pair of first inclined surfaces 24i whose separation distance gradually increases as the insertion portion 24b extends from the bottom surface 24h toward the base 23. The insertion portion 24b also has a pair of second inclined surfaces 24j whose separation distance gradually decreases as the insertion portion 24b extends from the ends of the pair of first inclined surfaces 24i on the base 23 side toward the base 23. The pair of first inclined surfaces 24i and the pair of second inclined surfaces 24j are curved so as to be convex outward. The ends of the pair of second inclined surfaces 24j on the base 23 side are connected to both side surfaces 24k of the protruding rib portion 24a.

[0084] 23 illustrates a state in which the fitting portion 24 of the fitting member 21 according to the first modified example and the groove portion 22 of the receiving member 20 having the same configuration as described above are fitted together, sandwiching the sheet materials 1, 10. As shown in the figure, the sheet materials 1, 10 are sandwiched between the inner surface 23b of the base 23 (the inner surfaces 23b of the pair of protrusions 23a) and the outer surfaces 22g of the pair of outer peripheral wall portions 20b of the receiving member 20. Furthermore, the sheet materials 1, 10 are sandwiched between both side surfaces 24k of the ridge portions 24a of the fitting portion 24 and both side surfaces 22c of the pair of outer peripheral wall portions 20b of the receiving member 20. Furthermore, the sheet materials 1, 10 are sandwiched between the bottom surfaces 24h of the insertion portions 24b and the bottom surfaces 22d of the groove portions 22.

[0085] [Second Modification] In the second modified example, the configuration of the receiving member 20 of the clamping jig 17 used in the clamping step included in the sealing step S2 is different from the configuration of the receiving member 20 described above. Only the differences will be described below. As shown in Fig. 24, the receiving member 20 according to the second modified example has a plurality of grooves 22 (two in the illustrated example) formed on the same plane of the receiving member 20. Note that the shape of these grooves 22 is the same as the shape of the grooves 22 described above, and therefore both the fitting portion 24 of the fitting member 21 shown in Fig. 15 and the fitting portion 24 of the fitting member 21 shown in Fig. 22 can be fitted into the grooves 22 of the receiving member 20 according to the second modified example.

[0086] [Third Modification] As shown in FIG. 25 , the third modified example uses a plurality of (two in the illustrated example) fitting members 21 according to the first modified example. The fitting portions 24 of the fitting members 21 and the plurality of (two in the illustrated example) grooves 22 of the receiving member 20 according to the second modified example are fitted to sandwich the sheet materials 1 and 10 (not shown). A characteristic feature of this third modified example is that a pressing member 28 is placed on the bases 23 of the fitting members 21, and a clamping mechanism 29 (a toggle clamping mechanism 29 in the illustrated example) applies a pressing force to the pressing member 28 toward the grooves 22. The pressing member 28 presses the bases 23 along its entire length. The pressing member 28 is made of a metal such as aluminum alloy, carbon steel, or stainless steel. The clamping mechanisms 29 are arranged at multiple locations along the longitudinal direction of the receiving member 20 and the fitting member 21. As a result, in the clamping process included in the sealing process S2, the clamp mechanism 29 presses the pressing member 28 and the base 23 toward the groove portion 22, thereby reliably preventing the fitting portion 24 from slipping out of the groove portion 22.

[0087] In this case, it is preferable to perform a process of rolling the roller-shaped pressing portion 30a of the pressing jig described above on the base 23 of the fitting member 21 in the longitudinal direction before placing the pressing member 28 on the base 23 of the fitting member 21, but this process may be omitted. Note that a fitting member 21 different from the illustrated example, such as that shown in Fig. 15, may also be used as the fitting member 21.

[0088] <<Article for manufacturing laminate>> An article for laminate manufacturing according to an embodiment of the present invention includes a temporary laminate 2, two sheet materials 1, 10, a clamping jig 17, and a bonding device. The temporary laminate 2 has the configuration already described with reference to Fig. 2. As already described with reference to Fig. 3, the two sheet materials 1, 10 sandwich the temporary laminate 2. As already described with reference to Figs. 17 and 23, the clamping jig 17 clamps the two sheet materials 1, 10. The bonding device includes a nozzle 11, a hose, a pump 31, a mounting member 4, and a heating device 32.

[0089] Although the embodiments of the present invention have been described above, the embodiments of the present invention are not limited to these, and various modifications are possible without departing from the spirit of the present invention.

[0090] For example, in the above embodiment, the clamping portion 18 by the clamping jig 17 is formed on a part of the planned sealing lines M1, M2, M3, and M4 to seal both sheet materials 1 and 10 into a bag, but the clamping portion 18 by the clamping jig 17 may be formed on all of such planned sealing lines while preventing the planned sealing lines M1, M2, M3, and M4 from intersecting. In this case, without performing the nozzle-periphery sealing step, an openable and closable exhaust port for exhausting gas from the inside may be provided in one of the sheet materials 10(1) in the region surrounded by the clamping portion 18 of both sheet materials 1 and 10, and gas may be supplied and exhausted through this exhaust port.

[0091] In the above embodiment, the temporary laminate 2 includes an adhesive sheet 8, but if the glass plate 9 and the resin plate 7 are bonded together by thermally melting both sides of the resin plate 7 during the heating process as the bonding process, the adhesive sheet 8 is not necessary.

[0092] In the above embodiment, the temporary laminate 2 includes the glass plate 9, adhesive sheet 8, and resin plate 7 as plate materials, but is not limited to these. In addition to these, it may also include a metal plate, a ceramic plate, etc. It may also include a decorative or functional resin film (e.g., a PET film), fiber, paper, etc.

[0093] In the above embodiment, the heating step is performed in the bonding step S4, but the heating step is not necessary if an adhesive or the like is used that can bond the resin plate 7 and the glass plate 9 by a pressing force (pressure force) generated by the exhaust step. That is, the bonding device in this case is the nozzle 11, the hose 12, and the pump 31.

[0094] In the above embodiment, the first sheet material 1 and the second sheet material 10 are separate members, but it is also possible to fold a single sheet material around the lateral center to double it, so that the sheet portion located on the lower side is the first sheet material 1 and the sheet portion located on the upper side is the second sheet material 10. In this case, the folded portion side of the single sheet material does not need to be clamped by the clamping jig 17.

[0095] In the above embodiment, the receiving member 20 and the fitting member 21 are integrated in the longitudinal direction, but they may be divided at one or more locations in the longitudinal direction. In this case, it is preferable that the divided portions are kept airtight when the sealing step is performed.

[0096] In the above embodiment, the receiving member 20 is made of the metal as described above, and the engaging member 21 is made of the resin or rubber as described above, but conversely, the engaging member 21 may be made of the metal as described above, and the receiving member 20 may be made of the resin or rubber as described above.

[0097] In the third modified example of the embodiment described above, the toggle clamp mechanism 29 is used, but any other mechanism may be used as long as it is capable of applying a pressing force to the pressing member 28 toward the groove portion 22 side. [Explanation of symbols]
