Description

[Technical field]

[0001] The present invention relates to a method for producing a plate-like material stack. [Background technology]

[0002] 2. Description of the Related Art Conventionally, as an example of a plate-like laminate formed by stacking a plurality of layers, a glass resin laminate has been known which is used in a wide range of fields, such as cover members for various devices and building materials, and which has excellent durability and light weight. The glass resin laminate is composed of thin glass sheets integrally laminated on both sides (or one side) of a resin plate with an intermediate film interposed therebetween that functions as an adhesive layer, and is mainly manufactured through a lamination process, a bonding process, a hole / edge processing process, a cleaning process, and an inspection / packaging process, which are carried out in sequence over time.

[0003] Here, the lamination process is a process of laminating, in a predetermined order, a group of components constituting each layer of the glass resin laminate (hereinafter referred to as a "glass resin component group" as appropriate), together with a backing plate and a release sheet required in the subsequent bonding process. The laminating step is a step of laminating the glass resin members laminated in the laminating step to each other by an autoclave method. After the laminating step is completed, the backing plate and the release sheet are removed from the glass resin members. The hole / edge processing step is a step in which holes and / or edges are processed in the group of glass resin members bonded together in the bonding step according to the specifications of the glass resin laminate, which is the final product. The cleaning step is a step in which the group of glass resin members processed by hole and edge processing is cleaned with a cleaning liquid, etc. In this way, a glass resin laminate is completed as a final product. Furthermore, the inspection and packaging process is a process in which quality inspection (e.g., checking the external size and the presence or absence of scratches, chips, dust, etc.) of the glass resin laminate completed upon completion of the cleaning process is carried out, and then the glass resin laminate is packaged in a specified packaging form. The glass resin laminate packaged in the inspection and packaging process is then stored in a predetermined storage location or shipped to a predetermined destination.

[0004] In the lamination process described above, the lamination work of the glass sheet, the intermediate film, the resin plate, the backing plate, and the release sheet that constitute the glass resin member group is mainly performed manually by an operator. Specifically, these glass resin component groups, as well as the backing plate and release sheet, are stacked in the following order: backing plate, release sheet, glass sheet, intermediate film, resin plate, intermediate film, glass sheet, release sheet, and backing plate. Among these, the glass sheet, intermediate film, and resin plate are components that constitute the final product, the glass resin laminate, and therefore need to be stacked while being aligned more accurately.

[0005] Here, for example, taking into consideration the characteristics and safety when using the glass resin laminate, the outer size of the resin plate is set slightly larger than the outer size of the glass sheet, and the resin plate is laminated with the edge face of the peripheral portion slightly protruding beyond the periphery of the glass sheet. On the other hand, the intermediate film interposed between the glass sheet and the resin plate is opaque, and its outer size is set to be sufficiently larger than the outer sizes of the glass sheet and the resin plate. Therefore, it is difficult to accurately grasp the position of the glass sheet located below the interlayer film from above the resin plate to be stacked on the interlayer film, and when performing the stacking operation in the lamination process, it is difficult to stack the resin plate on the interlayer film while accurately aligning it with the glass sheet.

[0006] As an example of a technique for stacking multiple components that have different outer sizes and need to be stacked with their end faces at different positions while aligning them more accurately, Patent Document 1, for example, discloses a technique in which multiple component components are stacked in order to form a stack, the stack is then inverted, and a new component is then stacked on top of the stack. That is, first, a laminate is formed by stacking a resin plate, an intermediate film, a glass sheet, a release sheet, and a backing plate in that order, and then the laminate is inverted and the intermediate film, a glass sheet, a release sheet, and a backing plate are again stacked on top of the resin plate in that order. In this way, the glass sheet, intermediate film, and resin plate, as well as the backing plate and release sheet that constitute the glass resin component group, can be easily stacked while being accurately aligned.

[0007] [Patent Document 1] JP 2019-217697 A Summary of the Invention [Problem to be solved by the invention]

[0008] However, in order to invert the stacked body that has been precisely aligned, a separate device is required to maintain the positions of the stacked components so that they do not shift when the body is inverted, which can result in increased equipment costs. Furthermore, in the lamination process, the lamination work of the glass sheet, intermediate film, and resin plate that constitute the glass resin component group, as well as the backing plate and release sheet, becomes more complicated due to the addition of an inversion operation, which may be a factor causing a deterioration in the quality of the glass resin laminate as a final product.

[0009] The present invention has been made in consideration of the current problems described above, and has an object to provide a method for manufacturing a plate-like material stack comprising a plurality of stacked layers, which can easily produce a high-quality plate-like material stack even when the end faces of the plurality of layers are at different positions from one another, without the need to invert the plurality of layers that have already been stacked during the stacking operation. [Means for solving the problem]

[0010] The problem to be solved by the present invention has been described above, and the means for solving this problem will now be described.

[0011] That is, the manufacturing method of the plate-like stack according to the present invention is a manufacturing method of a plate-like stack formed by stacking a plurality of layers, and includes a stacking process for stacking the plurality of layers in sequence so that the positions of the end faces are different from each other, and the stacking process is characterized by having a positioning process for positioning the second layer and subsequent layers after stacking a first layer and before stacking a second layer and subsequent layers to be stacked on the first layer, using a positioning device capable of disposing a regulating jig that regulates the stacking position of the second layer and subsequent layers. With this configuration, for example, when a glass sheet is laminated as the first layer, and an intermediate film and a resin plate are laminated on the glass sheet in that order as the second layer and subsequent layers, i.e., the second layer and the third layer, even if it is difficult to accurately grasp the position of the glass sheet through the intermediate film from above the resin plate to be stacked, as described above, it is possible to stack the resin plate on the intermediate film while accurately aligning it with the glass sheet using the regulating jig of the positioning device, without the need to invert the multiple layers that have already been stacked.

[0012] Furthermore, in the method for manufacturing a plate-like stack according to the present invention, it is preferable that the regulating jig has an abutment portion which comes into contact with the second layer and subsequent layers to position them, and is arranged so that the abutment portion can be displaced between a standby position located above and a regulating position located below for regulating the stacking position of the second layer and subsequent layers by rotating about an axis extending horizontally. With this configuration, the abutment portion can be displaced from the standby position to the regulating position for multiple layers that are stacked in order from bottom to top, without interfering with the layers that are already stacked.

[0013] Furthermore, in the method for manufacturing a plate-like stack according to the present invention, it is preferable that the positioning device is capable of placing a first layer regulating jig that regulates the stacking position of the first layer, the stacking process is performed before the positioning process is performed, and the method further includes a first layer positioning process in which the first layer regulating jig is placed before stacking the first layer to position the first layer. With this configuration, the first layer regulating jig of the positioning device can be used to accurately stack the first layer, that is, the glass sheet, in a predetermined stacking position relative to the second layer and subsequent layers, i.e., the intermediate film and the resin plate.

[0014] Furthermore, in the method for manufacturing a plate-like stack according to the present invention, it is preferable that the first layer regulating jig has a first layer abutment portion that contacts the first layer to position it, and is arranged so that the first layer abutment portion can be displaced between a standby position located above and a regulating position located below for regulating the stacking position of the first layer by rotating and moving about an axis extending horizontally. With this configuration, the first layer abutment portion can be displaced from the standby position to the regulating position for multiple layers that are stacked in sequence from bottom to top, without interfering with the layers that are already stacked.

[0015] In the method for producing a plate-like stack according to the present invention, it is preferable that in the first layer positioning step, the regulating jig is disposed in a state in which the second layer has been previously stacked on the first layer. With such a configuration, for example, when a glass sheet is stacked as a first layer on the upper surface of a release sheet, and then an interlayer film is stacked as a second layer on the upper surface of the glass sheet, it is possible to prevent the glass sheet from shifting in position relative to the release sheet, and a higher quality laminated form can be maintained.

[0016] In addition, in the manufacturing method of the plate-like stack of the present invention, in the stacking step, after completion of the positioning step, it is preferable that the regulating jig and the first layer regulating jig are both moved horizontally away from the stacked layers and removed. By having such a configuration, it is possible to perform accurate alignment, while retracting the regulating jig and the first layer regulating jig without interfering with the multiple layers stacked in order from bottom to top, thereby maintaining a high-quality stacked configuration.

[0017] In addition, in the manufacturing method of the plate-like material stack of the present invention, it is preferable that the positioning device has a position adjustment mechanism that is provided along the periphery of the multiple layers and is capable of independently adjusting the positions of the regulating jig and the first layer regulating jig in the approaching / moving away direction relative to the multiple layers. With this configuration, it is possible to reliably accommodate each type of plate-like material stack, even if there are many different types of plate-like material stacks with different external sizes, and it is possible to stack the multiple layers that make up each plate-like material stack while performing more accurate alignment.

[0018] In the method for producing a plate-like laminate according to the present invention, the second layer is preferably made of ethylene vinyl acetate. In this way, in the method for manufacturing a plate-like laminate of the present invention, even if opaque ethylene vinyl acetate is used as the second layer to be laminated to the first layer, it is possible to prevent misalignment of the second layer and subsequent layers relative to the first layer.

[0019] In addition, in the method for manufacturing a plate-like material stack according to the present invention, it is preferable that the multiple layers constituting the plate-like material stack are stacked in sequence on a support table, and the support surface of the support table is arranged to incline downwardly toward the positioning device. With such a configuration, for example, when a glass sheet is stacked as a first layer on the upper surface of a release sheet, and then an interlayer film is stacked as a second layer on the upper surface of the glass sheet, the positioning device can prevent the glass sheet from shifting in position relative to the release sheet, and a higher quality laminated form can be maintained.

[0020] Furthermore, in the method for manufacturing a plate-like laminate according to the present invention, it is preferable that the plate-like laminate has, in addition to the first layer and the second layer, at least a third layer laminated to the second layer, the first layer being a glass sheet, the second layer being an interlayer film, and the third layer being a resin plate. According to the method for manufacturing a plate-like laminate of the present invention, for a plate-like laminate having at least a glass sheet, an intermediate film, and a resin plate stacked in this order, these multiple components can be stacked while performing more accurate alignment.

[0021] In addition, in the manufacturing method of the plate-like stack of the present invention, it is preferable that the multiple layers are formed in a rectangular shape when viewed in a plane, and the positioning devices are provided in multiple numbers at least along two sides that sandwich a corner of the multiple layers. With this configuration, the stacking positions of the multiple layers constituting the plate-like material stack can be easily and accurately regulated by the positioning device. Effect of the Invention

[0022] The present invention has the following advantages. In other words, according to the method for manufacturing a plate-like material stack of the present invention, even if the positions of the end faces of the multiple layers constituting the plate-like material stack are different from each other, it is possible to easily obtain a high-quality plate-like material stack without the need to invert the multiple layers that have already been stacked during the stacking operation.

[0024] Next, an embodiment of the present invention will be described with reference to FIGS. For the sake of convenience, in the following description, the up-down direction, the front-rear direction, and the left-right direction of the stacking device 1 will be defined by the directions of arrows shown in FIGS. Moreover, the up-down direction and the front-rear direction of the stacking device 201 in another embodiment will be defined and described according to the directions of the arrows shown in FIG. Furthermore, the up-down direction, the front-rear direction, and the left-right direction of the positioning device 30 are defined and described by the directions of the arrows shown in FIG.

[0025] [Method of manufacturing plate-like laminate] First, a method for producing a plate-like stack, which is embodied in this embodiment, will be described with reference to FIGS. 1 to 3. FIG.

[0026] The method for manufacturing a plate-like laminate in this embodiment is a method for manufacturing a plate-like laminate formed by stacking multiple layers, and in the stacking step S01, even if the positions of the end faces of these multiple layers are different from each other, the method makes it possible to stack the multiple layers in a predetermined order while performing accurate alignment.

[0027] An example of the plate-like laminate manufactured in this embodiment is a glass resin laminate 110 that is used in a wide range of fields, such as cover members for various devices and building materials, and has excellent durability and light weight.

[0028] As shown in Figure 2, for example, the glass resin laminate 110 is composed of a resin plate 111, glass sheets 112 / 112 arranged on both sides and / or one side (both sides in this embodiment) of the resin plate 111, and intermediate films 113 / 113 respectively interposed between the resin plate 111 and the glass sheet 112.

[0029] The resin plate 111 is made of a material such as polycarbonate, acrylic, PET (polyethylene terephthalate), COP (cycloolefin polymer), or PVC (polyvinyl chloride), and is formed in the shape of a rectangular plate. The thickness of the resin plate 111 is preferably 0.2 mm to 50 mm, more preferably 0.5 mm to 20 mm, and further preferably 1 mm to 15 mm. The resin plate 111 may be either transparent or opaque.

[0030] The glass sheet 112 is formed into a rectangular sheet, and its material is preferably silicate glass or silica glass, more preferably borosilicate glass, soda-lime glass, or aluminosilicate glass, and even more preferably alkali-free glass. The use of alkali-free glass improves transparency and prevents deterioration due to alkali elution. From the viewpoints of strength and light weight, the thickness of glass sheet 112 is preferably 0.01 mm to 1 mm, more preferably 0.03 mm to 0.8 mm, and even more preferably 0.05 mm to 0.5 mm.

[0031] The glass sheet 112 may be formed by a downdraw method such as an overflow downdraw method, a slot downdraw method, or a redraw downdraw method, or a float method. The pair of glass sheets 112 arranged on both sides of the resin plate 111 may use the same type of glass composition, or different types of glass compositions. Furthermore, the thicknesses of the pair of glass sheets 112 may be the same or different from each other.

[0032] The intermediate film 113 is a member that functions as an adhesive for bonding the resin plate 111 and the glass sheet 112 together, and is formed in a rectangular sheet shape. The material of the intermediate film 113 is not particularly limited, and a thermoplastic adhesive sheet, a thermally crosslinkable adhesive sheet, etc. can be used. For example, EVA (ethylene vinyl acetate), TPU (thermoplastic polyurethane), COP, an acrylic thermoplastic adhesive sheet, etc. can be used.

[0033] In this embodiment, the intermediate film 113 is made of an EVA (ethylene vinyl acetate) based thermoplastic adhesive sheet, which generally has a rough surface and a high coefficient of friction. This makes it possible to prevent the resin plate 111 and the glass sheet 112, which are laminated with the intermediate film 113 in between, from shifting from one another in position. Moreover, the intermediate film 113 made of EVA is opaque and becomes transparent when heated.

[0034] The thickness dimension of the intermediate film 113 is preferably 0.025 mm to 2 mm, more preferably 0.05 mm to 1.6 mm, and further preferably 0.1 mm to 0.8 mm.

[0035] These groups of components 111, 112, 113 (hereinafter referred to as "glass resin group of components 110A" as appropriate) that make up the glass resin laminate 110 are stacked in order by hand in the lamination process S01, together with a backing plate 121 and a release sheet 122 that are required when performing the autoclave method in the bonding process that follows the lamination process S01, thereby constructing the laminated structure 101. Specifically, in the lamination process S01, the glass resin component group 110A, the backing plate 121 and the release sheet 122 are laminated in the order of the backing plate 121, the release sheet 122, the glass sheet 112, the intermediate film 113, the resin plate 111, the intermediate film 113, the glass sheet 112, the release sheet 122, and the backing plate 121 to construct the laminated structure 101.

[0036] Thus, the glass resin laminate 110 in this embodiment has a first layer and a second layer stacked from the bottom, and at least a third layer laminated on the second layer, with the first layer being formed by a glass sheet 112, the second layer being formed by an intermediate film 113, and the third layer being formed by a resin plate 111.

[0037] According to the method for manufacturing a plate-like laminate in this embodiment, a lamination step S01 is performed on a glass resin laminate 110 having at least a glass sheet 112, an intermediate film 113, and a resin plate 111 stacked in this order, using a lamination device 1 described later, whereby the multiple components 111, 112, 113 can be stacked while achieving more accurate alignment.

[0038] The backing plate 121 may be a glass plate of the same type as the glass sheet 112 or a different type of glass composition, or a metal or ceramic plate, but in this embodiment, for example, it is a rectangular flat glass plate made of soda-lime glass. From the viewpoint of strength, the thickness dimension of the backing plate 121 is set to be sufficiently larger than the thickness dimension of the glass sheet 112, and the outer size thereof is set to be approximately the same as the outer size of the resin plate 111.

[0039] On the other hand, the release sheet 122 is made of a resin sheet with a small coefficient of friction, and in this embodiment, for example, is formed into a rectangular sheet made of PET. In addition, the outer size of the release sheet 122 is preset to be sufficiently larger than the outer size of the backing plate 121, and the release sheet 122 is interposed between the backing plate 121 and the glass sheet 112 with the end face of its peripheral portion sufficiently protruding from the periphery of the backing plate 121.

[0040] The members in the glass resin member group 110A are preset to have different outer sizes. Specifically, for example, taking into consideration the slight shrinkage of the resin plate 111 when performing the above-mentioned autoclave method, as well as other reasons, the outer size of the resin plate 111 is preset to be slightly larger than the outer size of the glass sheet 112. In addition, the outer size of the intermediate film 113 is preset to be sufficiently larger than the outer sizes of the resin plate 111 and the glass sheet 112 so that it is interposed over the entire contact surface between the resin plate 111 and the glass sheet 112.

[0041] Then, in the lamination step S01, the resin plate 111 is laminated in a state in which the edge surface 111a of the peripheral portion slightly protrudes from the edge surface 121a of the peripheral portion of the glass sheet 112 by a dimension X (in this embodiment, the dimension X=approximately 1 mm).

[0042] As described above, the intermediate film 113 interposed between the glass sheet 112 and the resin plate 111 is opaque, and its outer size is set to be sufficiently larger than the outer sizes of the glass sheet 112 and the resin plate 111. Therefore, it is difficult to accurately grasp the position of the glass sheet 112 located below the intermediate film 113 from above the resin plate 111 to be stacked on the intermediate film 113. Therefore, in the lamination step S01, it is relatively easy to stack the backing plate 121, the release sheet 122, the glass sheet 112, and the intermediate film 113 in that order, but it is difficult to subsequently stack the resin plate on the intermediate film 113 while accurately aligning it with the glass sheet 112.

[0043] Therefore, in this embodiment, a positioning device 30 provided in the lamination device 1 described later is used to position the resin plate 111 at least after lamination of the glass sheet 112 and before lamination of the resin plate 111 (resin plate positioning step S14 described later), making it possible to accurately laminate the resin plate 111 in a predetermined position, thereby improving the quality of the constructed laminated structure 101.

[0044] Specifically, as shown in FIG. 1, the lamination process S01 includes a backing plate / release sheet lamination process S11, a glass sheet positioning process S12, an intermediate film lamination process S13, and a resin plate positioning process S14, and a laminated structure 101 is constructed through each of these processes.

[0045] The backing plate / release sheet lamination step S 11 is a step of stacking the backing plate 121 and the release sheet 122 in this order on the support table 10 of the lamination device 1 . Specifically, in the lamination device 1, a stopper 20 that regulates the position of a backing plate 121 is provided on the support table 10, and the backing plate 121 is placed on the support table 10 while being positioned by the stopper 20, and then a release sheet 122 is laminated on the upper surface of the backing plate 121.

[0046] The glass sheet positioning step S12 is an example of a first layer positioning step, and is a step of stacking and laminating the glass sheet 112 while performing accurate alignment on the upper surface of the release sheet 122 laminated in the backing plate / release sheet lamination step S11. Specifically, as described later, the positioning device 30 is provided with a glass sheet regulating jig 34 that regulates the stacking position of the glass sheet 112. After completion of the backing plate / release sheet stacking process S11, the glass sheet regulating jig 34 is placed at a predetermined position (regulating position P12, described later; see FIG. 5(b)). Thereafter, the glass sheet 112 is stacked on the upper surface of the release sheet 122 while being positioned by the glass sheet regulating jig 34.

[0047] Thus, in this embodiment, before the resin plate positioning process S14 described later is performed and before the glass sheet 112 is laminated as the first layer of the glass resin laminate 110, a glass sheet positioning process S12 is included in which the glass sheet 112 is positioned using a glass sheet regulating jig 34, which is an example of a first layer regulating jig. With this configuration, the glass sheet regulating jig 34 of the positioning device 30 can be used to accurately stack the first layer, the glass sheet 112, in a predetermined stacking position relative to the second layer and subsequent layers, i.e., the intermediate film 113 and the resin plate 111.

[0048] The intermediate film laminating step S13 is a step of stacking an intermediate film 113 on the upper surface of the glass sheet 112 stacked in the glass sheet positioning step S12. Specifically, the interlayer film 113 is laminated as the second layer of the glass resin laminate 110 in a state in which it covers the entire upper surface of the glass sheet 112 and protrudes from the periphery of the glass sheet 112 .

[0049] The resin plate positioning step S14 is an example of a positioning step, and is a step of stacking the resin plates 111 on the upper surface of the intermediate film 113 laminated in the intermediate film lamination step S13 while performing accurate alignment. Specifically, as described below, the positioning device 30 is further provided with a resin plate regulating jig 35 that regulates the stacking position of the resin plate 111. After completion of the intermediate film lamination process S13, the resin plate regulating jig 35 is placed in a predetermined position (regulating position P22 described below; see Figure 6(a)), and then the resin plate 111 is laminated on the upper surface of the intermediate film 113 while being positioned by the resin plate regulating jig 35.

[0050] Thus, in this embodiment, at least after laminating the glass sheet 112 as the first layer of the glass resin laminate 110, and before laminating the intermediate film 113 and subsequent layers (in this embodiment, the resin plate 111) as the second layer to be laminated on the glass sheet 112, a resin plate positioning process S14 is included in which the resin plate 111 is positioned using a resin plate regulating jig 35, which is an example of a regulating jig. With this configuration, when a glass sheet 112 is laminated as a first layer, and an intermediate film 113 and a resin plate 111 are laminated on the glass sheet 112 in order as the second layer and subsequent layers, i.e., the second layer and the third layer, as described above, even if it is difficult to accurately grasp the position of the glass sheet 112 from above the resin plate 111 to be stacked, via the intermediate film 113, it is possible to stack the resin plate 111 on the intermediate film 113 while accurately aligning it with the glass sheet 112 using the resin plate regulating jig 35 of the positioning device 30, without the need to invert the multiple layers that have already been stacked.

[0051] After the resin plate positioning step S14 is completed, the intermediate film 113, the glass sheet 112, the release sheet 122, and the backing plate 121 are laminated on the laminated resin plates 111 in this order. In this way, the laminated structure 101 is constructed, and the lamination step S01 is completed.

[0052] In addition, in the stacking operation of these components 112, 113, 121, and 122 after completion of the resin plate positioning process S14, the outer size of the resin plate 111 is set slightly larger than the outer size of the glass sheet 112. Therefore, the position of the resin plate 111 covered with the highly flexible interlayer film 113, even though it is opaque, can be relatively easily grasped even from above the glass sheet 112. Therefore, the glass sheet 112 can be easily stacked on the interlayer film 113 while being accurately aligned with the resin plate 111.

[0053] [Overall configuration of stacking device 1] Next, the overall configuration of a lamination device 1 for performing the above-mentioned lamination step S01 will be described with reference to FIG.

[0054] The stacking device 1 mainly includes a support table 10, a stopper 20, a positioning device 30, and the like.

[0055] The support table 10 constitutes the base of the lamination device 1, and on the support table 10, the above-mentioned laminated structure 101 is constructed.

[0056] The support base 10 includes, for example, a frame 11 formed in a rectangular frame shape in a plan view, and a plurality of transport means 12 provided on the upper surface of the frame 11. The outer size (front-rear and left-right dimensions) of the frame 11 is set to be sufficiently larger than the outer size of the laminated structure 101 . In this embodiment, each transport means 12 has a plurality of roller ball bearings 12a that can roll in any direction, and is constituted by a free conveyor extending in one direction.

[0057] The plurality of conveying means 12 are arranged in parallel with each other with the roller ball bearings 12a facing upward, and are mounted on the upper surface of the frame 11.

[0058] The configuration of the conveying means 12 is not limited to this embodiment, and any configuration may be used as long as it is capable of moving the laminated structure 101 placed on the support base 10 in any direction approximately horizontally.

[0059] The stopper 20 regulates the contact plate 121, which is a component of the laminated structure 101, to a predetermined placement position P1 on the support base . The stoppers 20·20·20 are provided in multiple numbers (three in this embodiment) in one stacking device 1, and are arranged along at least two sides (in this embodiment, the two sides, the left end face and the rear end face) of the support plate 121, which has a rectangular shape in a plan view and is placed at the placement position P1. Each stopper 20 has a contact surface 20a that can come into contact with an end face of the backing plate 121, and is installed on the upper surface of the frame 11 with the contact surface 20a facing inward of the frame 11.

[0060] Then, the support plate 121 placed on the support base 10 is moved by the conveying means 12 and the above-mentioned two sides are pressed against the abutment surfaces 20a, 20a, 20a of the multiple stoppers 20, 20, 20, respectively, so that the position of the support plate 121 is regulated at the placement position P1.

[0061] The positioning device 30 is a component of the laminated structure 101, and regulates the lamination positions of the glass sheet 112 forming the first layer of the glass resin laminate 110 and the resin plate 111 forming the third layer. Multiple positioning devices 30·30·30 (three in this embodiment) are provided in one stacking device 1 and are arranged along the periphery of the resin plate 111 and glass sheet 112, which are rectangular in plan view and are stacked on the support plate 121 placed at the placement position P1. The positioning devices 30 are mounted on the upper surface of the frame 11 via fixing plates 31, which will be described later.

[0062] The detailed configuration of the positioning device 30 will be described later.

[0063] [Configuration of positioning device 30] Next, the configuration of the positioning device 30 will be described in detail with reference to FIGS. In addition, in Figure 3, the multiple positioning devices 30-30-30 provided in the stacking device 1 have the same configuration and only differ in their positioning relative to the frame 11. Therefore, in the following explanation, we will mainly describe the positioning device 30 (positioning device 30X in Figure 3) that is arranged along the rear end surface of the resin plate 111 (or the glass sheet 112) to be stacked at the placement position P1, and omit descriptions of the positioning devices 30 that are arranged at other positions as appropriate.

[0064] In FIG. 4(a), a positioning device 30 mainly includes a fixed plate 31, a movement restricting means 32, a movable plate 33, a glass sheet restricting jig 34, a resin plate restricting jig 35, and a position adjustment mechanism 36.

[0065] The fixed plate 31 constitutes the base of the positioning device 30 . In this embodiment, for example, the fixed plate 31 is formed of a rectangular flat plate member having sufficient rigidity, and is disposed with its flat surface facing in the vertical direction.

[0066] The movement restricting means 32 restricts the movement direction of the movable plate 33 . In this embodiment, the movement restriction means 32 is constituted by, for example, a linear guideway, and has a restriction rail 32A extending in one direction (in this embodiment, the front-rear direction) and a moving block 32B movable along the restriction rail 32A.

[0067] The movement restricting means 32 is disposed on the upper surface of the fixed plate 31 with the moving block 32B facing upward, and the restricting rail 32A is installed on the fixed plate 31.

[0068] The configuration of the movement restricting means 32 is not limited to this embodiment, and any configuration may be used as long as it is capable of restricting the movement direction of the moving plate 33.

[0069] The moving plate 33 supports a glass sheet regulating jig 34 and a resin plate regulating jig 35 . In this embodiment, for example, the moving plate 33 is formed of a rectangular flat plate member having sufficient rigidity.

[0070] The movable plate 33 is disposed above and parallel to the fixed plate 31, and is provided on the upper surface of the movable block 32B. As a result, the moving plate 33 is configured to be reciprocally movable in one horizontal direction (front-rear direction) relative to the fixed plate 31 while the moving direction is restricted by the movement restricting means 32.

[0071] As described above, the glass sheet regulating jig 34 is an example of a first layer regulating jig, and regulates the stacking position of the glass sheet 112 which is stacked as the first layer of the glass resin laminate 110 in the lamination process S01. The glass sheet regulating jig 34 includes a support member 34A, a rotating shaft 34B, a rotating member 34C, and a contact member 34D.

[0072] The support member 34A supports the rotating member 34C so as to be rotatable. As shown in FIG. 4(c), for example, the support member 34A has a support member side main body portion 34A1 extending in the vertical direction, and a base portion 34A2 provided at the lower end of the support member side main body portion 34A1 and having a smooth mounting surface 34A2a.

[0073] A through hole 34A1a is provided at the upper end of the support member side main body portion 34A1, penetrating in the horizontal direction and in a direction perpendicular to the moving direction of the moving plate 33 (in the left-right direction in this embodiment). Furthermore, the rotation shaft 34B is coaxially fitted into the through hole 34A1a.

[0074] As shown in FIG. 4(a), the support member 34A is disposed on one axial side (in this embodiment, the left side) of the through hole 34A1a on the upper surface of the movable plate 33, and is installed on the movable plate 33 via the mounting surface 34A2a with the position adjustment mechanism 36 described later interposed therebetween.

[0075] The rotating member 34C supports the abutting member 34D so as to be rotatable about the axis of the rotating shaft 34B. The rotating member 34C has, for example, a rotating member side main body portion 34C1 extending in a direction perpendicular to the axial direction (left-right direction) of the rotating shaft 34B (in this embodiment, the front-to-rear direction), and a pair of housing portions 34C2-34C2 provided at one end portion (in this embodiment, the rear end portion) in the direction in which the rotating member side main body portion 34C1 extends.

[0076] The pair of housing portions 34C2-34C2 are arranged opposite each other in the axial direction (left-right direction) of the rotating shaft 34B, and the distance between them is set slightly larger than the width dimension (left-right dimension) of the upper end portion of the support member side main body portion 34A1. Further, the pair of housing portions 34C2 are each provided with through holes 34C2a that penetrate coaxially in the axial direction (left-right direction).

[0077] On the other hand, as shown in FIG. 4(c), a protrusion 34C3 that protrudes downward is provided at the other end (in this embodiment, the front end) in the extending direction of the rotating member side main body portion 34C1, and a smooth mounting surface 34C3a is formed at the lower end of the protrusion 34C3. Further, a contact member 34D is attached to the front side of the rotating member side main body portion 34C1 via a mounting surface 34C3a.

[0078] The rotating member 34C is arranged so that the upper end portion of the support member side main body portion 34A1 is interposed between the pair of housing portions 34C2·34C2, and the pair of through holes 34C2a·34C2a are positioned coaxially with the through hole 34A1a of the support member side main body portion 34A1. Further, a bearing member (not shown) such as a bushing is provided in the pair of through holes 34C2a, 34C2a, and the rotating shaft 34B is fitted into these through holes 34A1a, 34C2a, 34C2a which are coaxially arranged. As a result, the rotating member 34C, together with the abutting member 34D attached to the attachment surface 34C3a, is provided so as to be rotatable in the vertical direction about the axis of the rotating shaft 34B extending horizontally relative to the support member 34A.

[0079] The contact member 34D comes into contact with an end face of the glass sheet 112 when regulating the lamination position of the glass sheet 112 to be laminated as the first layer of the glass resin laminate 110. 4(a), the contact member 34D is an example of a first layer contact portion and is formed of a substantially rectangular flat thermoplastic resin member having an arc-shaped contact end surface 34D1. Note that the shape of the contact member 34D is not limited to this embodiment, and may be any shape as long as it has the above-mentioned contact end surface 34D1. The thickness of the contact member 34D is set to be slightly larger than the thickness of the glass sheet 112.

[0080] As shown in FIG. 4(c), the contact member 34D is attached to the attachment surface 34C3a with its plane facing up and down and with the contact end surface 34D1 protruding further forward from the front end of the rotation member side main body portion 34C1.

[0081] In this way, the glass sheet regulating jig 34 is configured so that the abutment end face 34D1 can be displaced between a waiting position P11 located above and a regulating position P12 located below, which regulates the stacking position of the glass sheet 112, by rotating the rotating member 34C around the axis of the rotating shaft 34B extending horizontally (left-right). Therefore, in the stacking process S01, the abutment end face 34D1 can be displaced from the waiting position P11 to the regulating position P12 for multiple layers (glass resin member group 110A, as well as the backing plate 121 and release sheet 122) stacked in sequence from bottom to top, without interfering with the backing plate 121 and release sheet 122 that have already been stacked.

[0082] When positioned at the regulating position P12, the lower surface of the abutment member 34D is set to be located on approximately the same imaginary horizontal plane as the lower surface of the glass sheet 112 to be laminated as the first layer, and by pressing the end surface of the glass sheet 112 against the abutment end surface 34D1 of the abutment member 34D, the stacking position of the glass sheet 112 is regulated and the glass sheet 112 is positioned.

[0083] As described above, the resin plate regulating jig 35 is an example of a regulating jig, and regulates the stacking position of the resin plate 111 that is stacked as the third layer of the glass resin laminate 110 in the stacking step S01. As shown in FIG. 4(a), the resin plate regulating jig 35 includes a support member 35A, a rotating shaft 35B, and a rotating member 35C.

[0084] The support member 35A supports the rotating member 35C via the moving plate 33 so as to be rotatable. The support member 35A has a configuration substantially identical to that of the support member 34A of the glass sheet regulating jig 34 described above, and, for example, as shown in Figure 4(b), has a support member side main body portion 35A1 extending in the vertical direction, and a base portion 35A2 provided at the lower end of the support member side main body portion 35A1 and having a smooth mounting surface 35A2a.

[0085] A through hole 35A1a that penetrates in the horizontal direction and in a direction perpendicular to the moving direction of the moving plate 33 (left and right direction) is provided at the upper end of the support member side main body portion 35A1. Furthermore, the rotation shaft 35B is coaxially fitted into the through hole 35A1a.

[0086] As shown in FIG. 4(a), the support member 35A is positioned on the other axial side (in this embodiment, the right side) of the through hole 35A1a on the upper surface of the movable plate 33, and is installed on the movable plate 33 via the mounting surface 35A2a with the position adjustment mechanism 36 described later interposed therebetween.

[0087] The pivoting member 35C is rotatably movable around the axis of the pivoting shaft 35B, and comes into contact with the end face of the resin plate 111 when regulating the stacking position of the resin plate 111 which is stacked as the third layer of the glass resin laminate 110. The rotating member 35C has, for example, a rotating member side main body portion 35C1 extending in a direction perpendicular to the axial direction (left-right direction) of the rotating shaft 35B (in this embodiment, the front-rear direction), and a pair of housing portions 35C2-35C2 provided at one end portion (in this embodiment, the rear end portion) in the direction in which the rotating member side main body portion 35C1 extends.

[0088] The pair of housing portions 35C2-35C2 are arranged opposite each other in the axial direction (left-right direction) of the rotating shaft 35B, and the distance between them is set slightly larger than the width dimension (left-right dimension) of the upper end portion of the support member side main body portion 35A1. Further, the pair of housing portions 35C2 and 35C2 are each provided with through holes 35C2a and 35C2a that penetrate coaxially in the axial direction (left-right direction).

[0089] On the other hand, as shown in FIG. 4(b), the other end (in this embodiment, the front end) in the extending direction of the rotating member side main body portion 35C1 is provided with an extending portion 35C3 extending downward, and the front side surface of the extending portion 35C3 is formed in an arc shape in a plan view and is configured as a contact side surface 35C3a that can come into contact with the end surface of the resin plate 111.

[0090] The rotating member 35C is arranged so that the upper end portion of the support member side main body portion 35A1 is interposed between the pair of housing portions 35C2·35C2, and the pair of through holes 35C2a·35C2a are positioned coaxially with the through hole 35A1a of the support member side main body portion 35A1. Further, a bearing member (not shown) such as a bushing is provided in the pair of through holes 35C2a, 35C2a, and the rotating shaft 35B is fitted into these through holes 35A1a, 35C2a, 35C2a which are coaxially arranged. As a result, the rotating member 35C is provided so as to be rotatable in the vertical direction with respect to the support member 35A about the axis of the rotating shaft 35B extending in the horizontal direction.

[0091] In this way, the resin plate regulating jig 35 is configured so that the contact side surface 35C3a can be displaced between a waiting position P21 located above and a regulating position P22 located below, which regulates the stacking position of the resin plate 111, by rotating the rotating member 35C around the axis of the rotating shaft 35B extending horizontally (left-right). Therefore, in the stacking process S01, the contact side surface 35C3a can be displaced from the waiting position P21 to the regulating position P22 for the multiple layers (glass resin member group 110A, as well as the backing plate 121 and release sheet 122) stacked in sequence from bottom to top, without interfering with the backing plate 121, release sheet 122, glass sheet 112, and intermediate film 113 that are already stacked.

[0092] When positioned at the regulating position P22, the lower surface of the pivotable member 35C is set to be located on approximately the same imaginary horizontal plane as the lower surface of the resin plate 111 laminated as the third layer, and by pressing the end surface of the resin plate 111 against the abutment side surface 35C3a, the laminated position of the resin plate 111 is regulated and the resin plate 111 is positioned.

[0093] The position adjustment mechanism 36 enables the positions of the glass sheet regulating jig 34 and the resin plate regulating jig 35 on the moving plate 33 to be adjusted independently. In this embodiment, the position adjustment mechanism 36 is, for example, made of a rectangular band-like member, and a plurality of oval through-holes 36a... are formed in the plane thereof at predetermined positions.

[0094] Here, the position adjustment mechanisms 36·36 are each arranged between the movable plate 33 and the support member 34A of the glass sheet regulating jig 34 and the support member 35A of the resin plate regulating jig 35, with their planes facing in the vertical direction and the longitudinal direction of the through hole 36a facing in the movement direction of the movable plate 33 (front-back direction). In addition, each position adjustment mechanism 36 is fixed on the upper surface to the support member 34A of the glass sheet regulating jig 34 or the support member 35A of the resin plate regulating jig 35 using a fastening member 51, and is fixed on the lower surface to the movable plate 33 via the through hole 36a using a fastening member 52.

[0095] On the other hand, as described later, the positioning device 30 is positioned with the abutment end surface 34D1 of the glass sheet regulating jig 34 and the abutment side surface 35C3a of the resin plate regulating jig 35 facing the resin plate 111 and the glass sheet 112 stacked at the loading position P1. Then, by sliding the fastening member 51 along the longitudinal direction of the through hole 36a and moving each position adjustment mechanism 36 in the movement direction (front-to-back direction) of the movable plate 33, the positioning positions of the glass sheet regulating jig 34 and the resin plate regulating jig 35 on the movable plate 33 can be independently adjusted in the approach direction (in this embodiment, the front direction) and the separation direction (in this embodiment, the rear direction) relative to the resin plate 111 and the glass sheet 112.

[0096] By providing a position adjustment mechanism 36 having such a configuration, even if there are many types of glass resin laminates 110 with different outer sizes, it is possible to reliably accommodate resin plates 111 and glass sheets 112 with different outer sizes in each type of glass resin laminate 110, and these resin plates 111 and glass sheets 112 can be laminated while performing more accurate alignment.

[0097] The configuration of the position adjustment mechanism 36 is not limited to this embodiment, and any configuration may be used as long as it is capable of adjusting the positions of the glass sheet regulating jig 34 and the resin plate regulating jig 35 on the movable plate 33 independently.

[0098] As described above, multiple (three) positioning devices 30·30·30 having the above-mentioned configuration are provided in one stacking apparatus 1, and are installed on the upper surface of the frame 11 with the abutment end surface 34D1 of the glass sheet regulating jig 34 and the abutment side surface 35C3a of the resin plate regulating jig 35 facing toward the inside of the frame 11, as shown in Figure 3. Specifically, these multiple positioning devices 30·30·30 are arranged along at least two sides (in this embodiment, the left end surface and the rear end surface) of the resin plate 111 and the glass sheet 112, which are rectangular in plan view and stacked at the placement position P1, that are sandwiched between the corners of the resin plate 111 and the glass sheet 112.

[0099] With this configuration, when a glass sheet 112 is laminated as the first layer of the glass resin laminate 110 or a resin plate 111 is laminated as the third layer in the lamination process S01, the lamination position can be easily and accurately regulated by simply pressing the two sides of the glass sheet 112 and the resin plate 111 that sandwich the corner against the abutment end face 34D1 of the glass sheet regulating jig 34 or the abutment side face 35C3a of the resin plate regulating jig 35.

[0100] As described above, each positioning device 30 is configured to allow the glass sheet regulating jig 34 and the resin sheet regulating jig 35 to be moved back and forth in one horizontal direction together with the movable plate 33 by the movement restricting means 32, and is configured to be able to move back and forth between a stacking position P31 on the upper surface of the frame 11, which is located on the close side to the loading position P1 and restricts the stacking position of the laminated resin plate 111 and glass sheet 112, and a retreat position P32, which is located on the far side from the loading position P1 and retreats from the laminated resin plate 111 and glass sheet 112.

[0101] [Operation procedure of positioning device 30] Next, the operation procedure of the positioning device 30 when performing the stacking step S01 using the stacking device 1 will be described with reference to FIGS.

[0102] First, in FIG. 3, the stacking device 1 is in an initial state, and the multiple positioning devices 30·30·30 are each moved to the retracted position P32. In addition, in each positioning device 30, the abutment end face 34D1 of the glass sheet regulating jig 34 is positioned at the standby position P11 as shown in Figure 4(c), and the abutment side face 35C3a of the resin plate regulating jig 35 is positioned at the standby position P21 as shown in Figure 4(b).

[0103] When the backing plate / release sheet stacking process S11 is started, an operator places a backing plate 121 on the upper surface of the support table 10, and then moves the placed backing plate 121 using the conveying means 12 and presses two sides (the left end face and the rear end face) of the backing plate 121 that are adjacent to a corner against the contact faces 20a / 20a / 20a of the multiple stoppers 20 / 20 / 20, thereby regulating the backing plate 121 to the placement position P1.

[0104] When the backing plate 121 is regulated to the placement position P1, the worker layers the release sheet 122 on the upper surface of the backing plate 121 with the peripheral edge portion slightly protruding from the periphery of the backing plate 121. This completes the backing plate / release sheet lamination step S11.

[0105] After laminating the release sheet 122 on the backing plate 121, the worker performs the glass sheet positioning step S12. Specifically, the worker moves each of the positioning devices 30 to the stacking position P31, and displaces the contact end surface 34D1 of each glass sheet regulating jig 34 to the regulating position P12, as shown in FIG. 5(b).

[0106] Here, the lower surface of the abutment member 34D at the regulating position P12 may be in either contact or non-contact with the upper surface of the release sheet 122, but if it is in a non-contact state, the gap between the abutment member 34D and the release sheet 122 needs to be set to be at least smaller than the thickness dimension of the glass sheet 112.

[0107] Then, the worker presses two sides (the left end face and the rear end face) of the glass sheet 112 that sandwich the corner against the abutment end faces 34D1·34D1·34D1 of the multiple abutment members 34D·34D·34D, and while positioning the glass sheet 112, laminates the glass sheet 112 on the upper surface of the release sheet 122. This completes the glass sheet positioning step S12.

[0108] After laminating the glass sheet 112 on the release sheet 122, the worker performs an intermediate film laminating step S13. Specifically, as shown in FIG. 5( c ), the worker laminates an intermediate film 113 on the glass sheet 112 so as to cover the entire upper surface of the glass sheet 112 . At this time, the intermediate film 113 is laminated in a state in which its peripheral portion protrudes from the periphery of the glass sheet 112, and the lower surface of the peripheral portion is in contact with the upper surface of the end of the abutting member 34D. This completes the intermediate film lamination step S13.

[0109] After laminating the intermediate film 113 on the glass sheet 112, the worker performs a resin plate positioning step S14. Specifically, as shown in FIG. 6(a), the worker displaces the contact side surface 35C3a of each of the resin plate regulating jigs 35 to the regulating position P22.

[0110] Here, the underside of the extension portion 35C3 displaced to the regulating position P22 may be in either contact or non-contact with the upper surface of the intermediate film 113, but if it is in a non-contact state, the gap between the underside of the extension portion 35C3 and the intermediate film 113 must be set to be at least smaller than the thickness dimension of the resin plate 111.

[0111] Then, as shown in Figure 6 (b), the worker presses two sides (the left end face and the rear end face) of the resin plate 111 that sandwich the corner against the abutting sides 35C3a·35C3a·35C3a of the multiple extension portions 35C3·35C3·35C3, and stacks the resin plate 111 on the upper surface of the intermediate film 113 while positioning the resin plate 111. This completes the resin plate positioning step S14.

[0112] After laminating the resin plate 111 on the upper surface of the intermediate film 113, the worker horizontally moves each of the positioning devices 30·30·30 toward the retracted position P32, as shown in FIG. 6(c), and then displaces the abutment end surface 34D1 of each glass sheet regulating jig 34 to the standby position P11 and displaces the abutment side surface 35C3a of each resin plate regulating jig 35 to the standby position P21. As a result, the stacking device 1 is returned to the initial state described above.

[0113] Thereafter, the worker stacks the intermediate film 113, the glass sheet 112, the release sheet 122, and the backing plate 121 on the stacked resin plates 111 in this order. In this way, the laminated structure 101 is constructed, and the lamination step S01 is completed.

[0114] The timing of performing the above-described return operation to the initial state in the stacking device 1 is not limited to this embodiment, and may be performed at any time at least after the end of the resin plate positioning process S14.

[0115] Thus, in this embodiment, in the lamination process S01, after the resin plate positioning process S14 is completed, each positioning device 30 (more specifically, the glass sheet regulating jig 34 and the resin plate regulating jig 35) is moved horizontally toward the retracted position P32, and retracted from the already laminated resin plate 111, glass sheet 112, and intermediate film 113.

[0116] With this configuration, after completion of the resin plate positioning process S14, accurate alignment can be performed while the glass sheet regulating jig 34 and the resin plate regulating jig 35 can be retracted without interfering with the resin plate 111, intermediate film 113, and glass sheet 112, which are stacked in order from bottom to top, and a high-quality stacked configuration can be maintained.

[0117] [Another embodiment] Next, another embodiment of the present invention will be described with reference to FIG.

[0118] As another embodiment of the lamination process S01 described above, in the glass sheet positioning process S12, an intermediate film 113 to be laminated as the second layer is pre-laminated on the glass sheet 112 to be laminated as the first layer of the glass resin laminate 110, and the glass sheet 112 and the intermediate film 113 are laminated together on the upper surface of the release sheet 122, and then the abutting side surface 35C3a of each resin plate regulating jig 35 is displaced to the regulating position P22 to position the resin plate regulating jig 35.

[0119] That is, when the glass sheet 112 is stacked on the upper surface of the release sheet 122 and then the intermediate film 113 is stacked on the upper surface of the glass sheet 112, the surface of the release sheet 122 is generally smooth and has a small coefficient of friction, while the surface of the intermediate film 113 is generally rough and has a large coefficient of friction, so that when the intermediate film 113 is stacked on the upper surface of the glass sheet 112, there is a risk that the glass sheet 112 will become misaligned with respect to the release sheet 122.

[0120] Therefore, as in the above-mentioned alternative embodiment, if the intermediate film 113 is stacked in advance on the upper surface of the glass sheet 112, and then the glass sheet 112 and the intermediate film 113 are stacked together on the upper surface of the release sheet 122, it is possible to prevent the glass sheet 112 from shifting in position relative to the release sheet 122, and a higher quality laminated form can be maintained.

[0121] In addition, as another embodiment of the stacking device 1 described above, a stacking device 201, as shown in Figure 7, on a support base 210, a support surface Sa that supports the stacked structure 101 and is formed by the upper ends of multiple conveying means 212·212··· may be configured to be inclined downward toward each positioning device 230 and to form an angle θ with respect to a horizontal plane Y. More specifically, for example, when a plurality of positioning devices 230·230·· are provided along two sides that sandwich a corner of a resin plate 111 and a glass sheet 112 that are rectangular in plan view and stacked at the placement position P1, the support surface Sa of the support base 210 may be configured to be inclined downward toward the corner.

[0122] With this configuration, the laminated structure 101 supported on the support surface Sa of the support base 210 is constantly pressed against the plurality of positioning devices 230 by its own weight. Therefore, when the glass sheet 112 is stacked on the upper surface of the release sheet 122 and then the intermediate film 113 is stacked on the upper surface of the glass sheet 112, even if the glass sheet 112 slips on the upper surface of the release sheet 122 and becomes misaligned, these multiple positioning devices 230·230·· can reliably prevent such misalignment, and a higher quality laminated form can be maintained.

[0123] Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, which are merely illustrative, and it goes without saying that the present invention can be embodied in various other forms without departing from the gist of the present invention.
