Description

Technical Field

[0001] The present invention relates to a package for supporting a composite laminate in a longitudinal orientation, wherein the composite laminate is formed by stacking a composite on a glass plate with a resin film disposed thereon. Background Technology

[0002] For example, electronic devices such as solar cell panels (PV), liquid crystal panels (LCD), organic OLED panels, and sensor panels that detect electromagnetic waves, X-rays, ultraviolet rays, visible light, infrared light, etc., are constantly being made thinner and lighter. Along with this, the supporting substrates, such as polyimide resin substrates used in electronic devices, are also becoming increasingly thinner.

[0003] If the strength of the support substrate decreases due to thinning, the operability of the support substrate decreases. In processes such as forming electronic components on the support substrate (component forming process), problems such as deformation of the support substrate and damage to the circuit may sometimes occur.

[0004] Therefore, as shown in Patent Document 1, recently, in order to improve the operability of the support substrate, a technology has been proposed, for example, to use a composite material made of a resin film such as polyimide resin disposed on the main surface of a glass plate as a support substrate.

[0005] In addition, Patent Document 2 shows a storage container for accommodating multiple glass plates. In the aforementioned glass plate composite, the glass plates are sometimes stacked in the storage container and stored as a composite stack. Furthermore, in order to prevent the composite from shifting, it is transported by binding with straps.

[0009] Patent Document 2: Japanese Patent Application Publication No. 2011-63274 Summary of the Invention

[0010] The problem that the invention aims to solve

[0011] However, the composite has a resin film disposed on the main surface of the glass plate, except near the outer edge. Therefore, as described above, when multiple composites are stacked in a storage container and bundled together, spaces are created between adjacent composites in the stacking direction at the ends of the glass plates. That is, in a composite stack formed by stacking composites, a space is created between the end of the glass plate of the Nth composite (N is an integer greater than or equal to 1) and the end of the glass plate of the (N+1)th composite.

[0012] Furthermore, when it is desired to use a belt to suppress the movement of the composite and prevent it from shifting, the edge portion of the component inside the belt of the composite stack is bent, thereby concentrating the force at that edge portion. Therefore, at the point of force concentration, the end of the glass plate generating space may deform, or the distance between the glass plates may shorten, causing the glass plates to come into contact with each other during transport, which may result in cracks or defects in the glass plates.

[0013] Therefore, the object of the present invention is to provide a bundle for composite laminates that can suppress the movement of the composite and the contact between the glass plates of the composite during transport, thereby suppressing the deformation, cracking and defects of the glass plates.

[0014] Technical solutions for solving the problem

[0015] The present invention is composed of the following structure.

[0016] (1) A bundle for a composite laminate, supporting the composite laminate in a longitudinal orientation, wherein the composite laminate is formed by stacking multiple composite layers with resin films disposed on the main surface of a glass plate, wherein the bundle for the composite laminate comprises:

[0017] The bottom support portion supports the downward-facing end face of the composite laminate;

[0018] A back support portion supports the back side of the composite laminate in a state in which the main surface of the glass plate is inclined from the vertical direction.

[0019] The pressing part is disposed on the front surface side of the composite laminate opposite to the back side and contacts the surface of the composite laminate.

[0020] A fastening mechanism applies a fastening force to the composite laminate sandwiched between the pressing portion and the back support portion at a fastening position on a portion of the pressing portion.

[0021] The fastening mechanism is provided only in the central region of the composite laminate in the vertical direction, or in both the upper and lower regions in the vertical direction, or in all of the upper, central, and lower regions.

[0022] When the composite laminate is viewed from a direction perpendicular to the main surface of the glass plate, the distance between the ends of the glass plate from the end of the composite laminate in the region corresponding to the fastening position to the nearest end of the resin film is 5 mm or more and 30 mm or less.

[0023] The average distance between the facing surfaces of a plurality of adjacent glass plates in the region corresponding to the fastening position of the composite laminate, i.e., the gap distance, is 20 μm or more and is less than 80% of the thickness of the resin film before fastening.

[0024] (2) A bundle for a composite laminate, supporting the composite laminate in a longitudinal orientation, wherein the composite laminate is formed by stacking multiple layers of a composite having a resin film disposed on the main surface of a glass plate, with protective sheets separating the resin film layers, wherein the bundle for the composite laminate comprises:

[0025] The bottom support portion supports the downward-facing end face of the composite laminate;

[0026] A back support portion supports the back side of the composite laminate in a state in which the main surface of the glass plate is inclined from the vertical direction.

[0027] The pressing part is disposed on the front surface side of the composite laminate opposite to the back side and contacts the surface of the composite laminate.

[0028] A fastening mechanism applies a fastening force to the composite laminate sandwiched between the pressing portion and the back support portion at a fastening position on a portion of the pressing portion.

[0029] The fastening mechanism is provided only in the central region of the composite laminate in the vertical direction, or in both the upper and lower regions in the vertical direction, or in all of the upper, central, and lower regions.

[0030] When the composite laminate is viewed from a direction perpendicular to the main surface of the glass plate, the distance between the ends of the glass plate from the end of the composite laminate in the region corresponding to the fastening position to the nearest end of the resin film is 5 mm or more and 30 mm or less.

[0031] The average distance, i.e. the gap distance, between the plurality of glass plates in the region corresponding to the fastening position of the composite laminate and the protective sheet in contact with the resin film disposed on the main surface of the glass plate is 20 μm or more, and is less than 80% of the total thickness of the resin film and the protective sheet before fastening.

[0049] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0050] (First Implementation)

[0051] First, the packaging body of the composite laminate involved in the first embodiment will be described.

[0052] Figure 1 This is a perspective view showing the package of the composite laminate according to the first embodiment. Figure 2A This is a top view of the main side of composite 1 where the resin film R is provided. Figure 2B This is a side view taken from the first side G1 of the complex 1. Figure 3 This is a side view of a part of composite 1.

[0053] like Figure 1 As shown, the bundle of the composite laminate involved in the first embodiment is a bundle in which a composite laminate 2 formed by stacking multiple composite sheets 1 is bundled. The composite laminate 2, which is contained in the storage container 100 and becomes a bundle, is loaded onto a transport vehicle (e.g., a trailer or truck), a ship, etc. for transportation and delivery.

[0054] like Figure 2A and Figure 2B As shown, the composite 1 constituting the composite laminate 2 is a plate-shaped body having a glass plate G and a resin film R disposed on the main surface of the glass plate G. This composite 1 is used, for example, as a support substrate in the process of forming components for electronic devices.

[0055] The glass plate G is rectangular in shape when viewed from a direction perpendicular to the main surface, and has a first side G1 and a second side G2 that are parallel to each other, as well as a third side G3 and a fourth side G4 that are parallel to each other. In this embodiment, the glass plate G is, for example, a large-sized glass plate of sixth-generation dimensions (1850 mm for the long side and 1500 mm for the short side), and has a thickness of 0.3 mm or more and 1.0 mm or less. Furthermore, the Young's modulus of the glass plate G in this embodiment is 60 GPa or more and 95 GPa or less. There are no particular limitations on the glass used to constitute the glass plate G; for example, known glasses such as alkali-free glass, soda-lime glass, and borosilicate glass can be used, with alkali-free glass being preferred.

[0056] The resin film R is rectangular in shape when viewed perpendicularly from the main surface of the glass plate G, and is disposed on the main surface of the glass plate G except for the area along the outer edge. The resin film R has a fifth side R5 and a sixth side R6 parallel to the first side G1 of the glass plate G, and a seventh side R7 and an eighth side R8 parallel to the third side G3 of the glass plate G. The resin film R has a thickness of, for example, 10 μm or more and 120 μm or less. Furthermore, the Young's modulus of the resin film R is 0.1 GPa or more and 7 GPa or less. Here, "parallel" means arranged side-by-side, but it can also mean parallel to each other.

[0057] like Figure 3 As shown, the resin film R disposed on the main surface of the glass plate G has a first resin film Ra for forming components for electronic devices and a second resin film Rb formed on the first resin film Ra in a peelable manner. The first resin film Ra is, for example, an organosilicon resin, and the second resin film Rb is, for example, a polyethylene terephthalate (PET) film. The second resin film Rb is a protective film that protects the first resin film Ra. That is, in the resin film R, the first resin film Ra for forming components for electronic devices is covered and protected by the second resin film Rb.

[0058] When the composite 1 is used as a support substrate for forming electronic devices, a second resin film Rb is peeled off from the first resin film Ra, and an electronic device, such as an organic EL (OLED), is formed on the first resin film Ra. After the electronic device is formed on the first resin film Ra, it is mechanically peeled off from the first resin film Ra. Thus, if the composite 1 formed by setting the resin film R on the glass plate G is used as a support substrate for forming electronic devices, the formed electronic device can be easily peeled off from the support substrate compared to the case where expensive laser devices are used to separate the electronic device from the support substrate.

[0059] Figure 1 The storage container 100 shown is placed on the upper surface of the pedestal 19. The storage container 100 is configured to include a back support portion 10, a bottom support portion 17 serving as a base plate, a pressing portion 30, and a fastening mechanism 15.

[0060] The back support portion 10 has a back support member 13 and a plate-shaped back bearing member 11. The back support member 13 supports the back side of the composite laminate 2 via the back bearing member 11 when the main surface of the glass plate G is inclined from the vertical direction. The opposite side of the back support member 13 of the back bearing member 11 becomes the bearing surface 23 of the composite laminate 2. This bearing surface 23 may also have a buffer sheet (not shown).

[0061] The back support portion 10 contacts the composite laminate 2 surface and supports the composite laminate 2 in a longitudinal posture against the back support member 11. The back support member 13 and the bottom support portion 17 are preferably made of a load-bearing material (e.g., iron, aluminum alloy, or resin).

[0062] Here, regarding the stacking direction of the composite 1, the side of the pressing portion 30 of the composite laminate 2 is referred to as the "front side" or "front surface side", and the side of the back support portion 10 is referred to as the "back side".

[0063] A bottom support portion 17 is provided on the upper part of the base 19, in front of the lower end of the back support member 11 (the support side supporting the composite laminate 2). The bottom support portion 17 is made of, for example, a sheet material, the upper surface of which serves as the mounting surface 27 of the composite laminate 2. The bottom support portion 17 is arranged with the mounting surface 27 inclined from the upper surface of the base 19. The mounting surface 27 preferably has a cushioning sheet (not shown).

[0064] The angle between the bearing surface 23 of the back support member 11 and the mounting surface 27 of the bottom support portion 17 is preferably approximately 90°. Furthermore, the side of the back support member 13 supporting the back support member 11 is preferably such that the angle θ between the main surface of the glass plate G of the composite laminate 2 and the vertical direction is 45° or more and 80° or less (see below). Figure 4 By forming this tilt angle, the composite laminate 2 can be stably supported on the back support portion 10.

[0065] Thus, the composite laminate 2 formed by the laminated composite 1 is placed on the bottom support 17 and stored in the storage container 100 in a longitudinal position against the back support 10.

[0066] In the composite laminate 2, a pressing part 30 is disposed on its front surface side (opposite to the back support part 10 side). The pressing part 30 has a pressing frame 33 and a resin plate 31 as a cushioning material disposed between the pressing frame 33 and the composite laminate 2. The pressing frame 33 is preferably made of a lightweight and non-deformable material (e.g., aluminum or aluminum alloy, resin, etc.).

[0067] The pressing part 30 is pressed against the composite laminate 2 by the fastening mechanism 15, pressing the composite laminate 2 toward the back support part 10.

[0068] The fastening mechanism 15 generates a fastening force that clamps the composite laminate 2 supported on the back support portion 10 between the pressing portion 30 and the back support portion 10. The fastening mechanism 15 shown in this embodiment includes a strip-shaped belt 15a and a tension applying portion 15b that applies tension to the belt 15a. In this example, the fastening mechanism 15 is arranged at two locations (upper region and lower region) that are at different heights of the composite laminate 2, and two belts 15a are horizontally mounted on the pressing frame 33 in front of the composite laminate 2, thereby fixing the composite laminate 2 to the back support portion 10. However, a single belt can also be horizontally mounted and fixed in the central region of the composite laminate 2 in the height direction. Alternatively, belts can be mounted in the upper region, lower region, and central region of the composite laminate 2 respectively.

[0069] Both ends of the belt 15a are fixed to the back support member 13, and a ratchet or tension application part 15b is provided on a portion of the belt at one end. Tension is applied to the belt 15a through the tension application part 15b. The tensioned belt 15a generates a fastening force that presses the composite laminate 2 against the back support member 10, holding the composite laminate 2 in a fixed state to the back support member 10, so that the composite laminate 2 is contained in the storage container 100.

[0070] The point of application of the fastening force preferably includes the end region of the glass plate G, but it can also be only the end region. The end region of the glass plate G means the area from the end of the glass plate G to the end of the resin film R when viewed from above. Figure 2A The regions shown are the third side G3 of the glass plate G and the seventh side of the resin film R, and the region between the fourth side G4 of the glass plate G and the eighth side R8 of the resin film R. By including the end region of the glass plate G as the point of application of the fastening force, the composite laminate 2 can be strongly fastened in the end region of the glass plate G. This structure, where the fastening force acts in the end region of the glass plate G, does not complicate the structure of the fastening mechanism 15 compared to, for example, fastening the entire main surface or the center of the main surface of the glass plate G, and allows for simple adjustment of the fastening force. Furthermore, even when the fastening force can only be applied to the end region of the glass plate G, stable fixation of the composite laminate 2 can be achieved by satisfying conditions such as the dimension between the ends of the glass plate G and the nearest end of the resin film R, and the distance between the facing surfaces of the glass plates, as described below.

[0071] The pressing part 30 is preferably in contact with the surface of the composite laminate 2. The pressing frame 33 is not limited to the grid-shaped frame shown in the figure, and may also be plate-shaped or block-shaped. Alternatively, other components or other shapes of pressing frames may be used instead of the pressing frame 33, such as thick paper, cushioning plates, etc., which are provided at the corners of the composite laminate 2 intersecting with the tape 15a and bent into an L-shape.

[0072] In this way, the bundle of composite laminate 2 transports and conveys composite laminate 2, which consists of multiple layers of composite 1 with resin film R disposed on the main surface of glass plate G, in a fixed longitudinal orientation. By fixing it in a longitudinal orientation, the space efficiency of the composite laminate 2 is improved.

[0073] Next, the specific storage state of the composite laminate 2 in the storage container 100 will be described. In the following description, the pressing part 30 (resin plate 31 and pressing frame 33), etc., are schematically shown or omitted. Also, the number of composite laminate 1 sheets shown in each figure is less than the actual number. Furthermore, in each figure, the direction parallel to the first edge G1 of the glass plate G of the composite laminate 1 is designated as the X-axis direction, the direction orthogonal to the X-axis direction and along the main surface of the glass plate G is designated as the Y-axis direction, and the direction perpendicular to the main surface of the glass plate G is designated as the Z-axis direction.

[0074] Figure 4 This is a schematic side view of the bundle of the composite laminate 2 according to the first embodiment. Figure 5 This is a schematic top view of the bundle of the composite laminate 2 according to the first embodiment. Figure 6 This is a schematic top view of a portion of the bundle of the composite laminate 2 according to the first embodiment. Figure 7 This is a schematic diagram viewed from above the composite stack 2 stored in the storage container 100.

[0075] like Figure 4 and Figure 5 As shown, each composite 1 is preferably stacked with the first edge G1 of the glass plate G facing downwards, such that the resin film R disposed on one main surface of the glass plate G is opposite to the other main surface (non-forming surface of the resin film R) of the adjacent glass plate G. In the housing container 100, each composite 1 is placed with the first edge G1 of the glass plate G, which is the downward-facing end face, abutting against and supported on the bottom support portion 17, and stacked with the main surfaces of each glass plate G inclined from the vertical direction as a composite laminate 2.

[0076] When the composite laminate 2 is arranged such that one main surface of the resin film R of each composite 1 faces the back support member 11, the other main surface of the glass plate G (the non-forming surface of the resin film R) becomes the front surface when the composite 1 is removed from the receiving container 100. Therefore, since the resin film R is not disposed on the removal side of the glass plate G, the glass plate G can be easily held without being aware of interference (contact) with the resin film R. As a result, the removal of each composite 1 from the composite laminate 2 is simplified.

[0077] The composite laminate 2, placed in the storage container 100, is secured between the pressing part 30 and the back support part 10 by a strap 15a mounted on its front surface, and is held against the back support member 13 by being pressed against the back bearing member 11. Thus, the composite laminate 2 becomes a bundled package stored in the storage container 100. At this time, as... Figure 5 As shown, the fastening mechanism 15 fastens the composite laminate 2 such that when pulled forward (Z direction) at 50N from the center in the width direction (X direction) of the composite laminate 2, the displacement α at the traction part is 20mm (refer to...). Figure 5 Thus, each composite 1 constituting the composite laminate 2 is pressed against the back support member 11 of the storage container 100 in a stacked state and is well held.

[0078] like Figure 6 As shown, the composite laminate 2, formed as a bundle, when viewed from the direction perpendicular to the main surface (Z direction) of the glass plate G of the composite 1, has an end dimension M from the end of the glass plate G intersecting with the belt 15a at the fastening position to the nearest end of the resin film R, which is 5 mm or more and 30 mm or less. Furthermore, when viewed from the direction perpendicular to the main surface (Z direction) of the glass plate G of the composite 1, at the end of the glass plate G intersecting with the belt 15a at the fastening position, the average value of the distance in the direction perpendicular to the main surface between the Nth (N is an integer greater than or equal to 1) glass plate G and the (N+1)th glass plate G from the top, i.e., the distance D (also called gap distance) between the facing surfaces of multiple adjacent glass plates G, is 20 μm or more, and is less than 80% of the thickness of the resin film R in a stress-free state before fastening by the fastening mechanism 15.

[0079] The average value of the gap distance D mentioned here (and the same applies to the second embodiment described later) can be the average value between the surfaces of all the glass plates G included in the composite laminate 2. For example, in the case of N glass plates G being stacked, it can be the average value of the gap distance D at point N-1, or it can be the average value of the gap distance D measured every n plates (e.g., n=10) in the order of stacking.

[0080] In this way, the average gap distance D between adjacent glass plates G of the composite laminate 2 is 20 μm or more, and the composite laminate 2 is fastened with a strength that reduces the gap distance D to less than 80% of the thickness of the resin film R. This allows the composite laminate 2 to be reliably fixed to the back support member 13. Furthermore, when the composite laminate 2 is transported in a bundled state housed in the storage container 100, movement of the laminated composite 1 and contact between the glass plates G can be suppressed. Therefore, deformation, cracking, and defects of the glass plates G can be suppressed.

[0081] When the end-to-end dimension M is less than 5 mm, the resin film R is positioned close to the end of the glass plate G. Therefore, damage such as damage to the resin film R is easily caused when handling the glass plate G. Furthermore, if the operator is particularly aware of the potential damage to the resin film R while handling the glass plate G, the workability of handling the glass plate G decreases. On the other hand, when the end-to-end dimension M exceeds 30 mm, the distance from the end of the glass plate G to the resin film R becomes longer, making it easier for the ends of the glass plate G to bend together when fastening the composite laminate 2, easily leading to damage such as cracks in the glass plate G. Therefore, an end-to-end dimension M of 5 mm or more and 30 mm or less is preferable.

[0082] Moreover, such as Figure 7 As shown, in the bundled state of the composite laminate 2, the difference between the maximum value Emax and the minimum value Emin of the distance E between the reference plane Sb perpendicular to the X-axis parallel to the first side G1 of the glass plate G and the position of the seventh side R7 in the X-axis direction as observed from the reference plane Sb is preferably 10 mm or less. For example, taking the seventh side R7 of the resin film on the glass plate G arranged furthest from the back support member 13 among the plurality of glass plates G of the composite laminate 2 as the reference plane, it is preferable that the difference between the maximum value Emax and the minimum value Emin of the distance E between the seventh side R7 serving as the reference plane and the seventh side R7 of the resin film on other glass plates G is 10 mm or less. As a result, when the composite laminate 2 is stored in the bundled state of the storage container 100, the lateral (X-direction) positional deviation of the laminated composite 1 is suppressed. As a result, stress concentration on the glass plate G caused by the lateral displacement of the composite 1 can be suppressed.

[0083] Furthermore, if the Young's modulus of the second resin film Rb is less than 0.1 GPa, the first resin film Ra is prone to deformation due to the weight of the laminate and the clamping force when the composite is laminated. When the first resin film Ra deforms, defects may occur in the device formed on the first resin film Ra. In addition, when the Young's modulus of the second resin film Rb exceeds 7 GPa, the warpage of the composite caused by the expansion and contraction of the second resin film Rb based on temperature and humidity tends to increase. When the warpage of the composite increases, the holding and transport of the substrate in the device fabrication process may become difficult. For the above reasons, the Young's modulus of the second resin film Rb is preferably 0.1 GPa or higher and 7 GPa or lower.

[0084] As explained above, the bundle of the composite laminate 2 according to the first embodiment can suppress the movement of the composite 1 and the contact between the glass plates G during transportation and conveying, thereby suppressing the deformation, cracks and defects of the glass plates G.

[0085] (Second Implementation)

[0086] Next, the packaging body of the composite laminate according to the second embodiment will be described.

[0087] In addition, in the following description, the same reference numerals are used for the same parts or locations as in the first embodiment, thereby omitting or simplifying their description.

[0088] Figure 8 This is a schematic side view of the bundle of the composite laminate 2A according to the second embodiment. Figure 9 This is a schematic top view of the bundle of the composite laminate 2A according to the second embodiment. Figure 10 This is a schematic top view of a portion of the bundle of the composite laminate 2A according to the second embodiment.

[0089] like Figure 8 and Figure 9 As shown, in the package of the composite laminate 2A according to the second embodiment, a protective sheet 3 is disposed on the resin film R side of the composite 1. The composite laminate 2A, which is formed by stacking multiple composites 1 with the protective sheet 3 between them, is stored in the storage container 100.

[0090] The protective sheet 3 is a sheet material that prevents the composites 1 from sticking together and protects each composite 1; for example, it may be made of paper or resin. Figure 8 and Figure 9 In this composite, the protective sheet 3 has approximately the same size as the glass plate G of the composite 1, but its size is not particularly limited as long as it can cover the entire surface of the resin film R. For example, the protective sheet 3 can be larger than the resin film R and smaller than the glass plate G. Alternatively, the protective sheet 3 can be larger than the glass plate G. When the protective sheet 3 is larger than the glass plate G, the protective sheet 3 extends from the side of the composite laminate 2A. Furthermore, the protective sheet 3 preferably has a rough surface, for example, with a smoothness of 18 seconds or less (JIS P8119, 1976). A material with a small contact area (paper) is selected to avoid the resin component of the protective sheet 3 being transferred to the composite 1, resulting in paper-like patterns, scorching, contamination, etc., in the composite 1. Moreover, the resin component of the protective sheet 3 is preferably, for example, 0.05% by mass or less (JIS P 8205, 1976). A material (paper) is selected that will not adversely affect the quality of the composite 1 itself due to the composite effect with the aforementioned smoothness.

[0091] Each composite 1 is preferably stacked with the first edge G1 of the glass plate G facing downwards and supported on the bottom support portion 17, such that one main surface of the glass plate G on which the resin film R is disposed faces the other main surface (the non-forming surface of the resin film R) of the adjacent glass plate G across the protective sheet 3. In the storage container 100, each composite 1 is placed with the first edge G1 of the glass plate G, which is the downward-facing end face, abutting against and supported on the bottom support portion 17, and is placed as a composite laminate 2A formed by stacking the main surfaces of each glass plate G together with the protective sheet 3 in a state of vertical inclination.

[0092] As described above, when the composite laminate 2A is arranged with the resin film R of each composite 1 facing the back support member 11, the other main surface of the glass plate G (the non-formed surface of the resin film R) becomes the front surface when the composite 1 is removed from the storage container 100. Therefore, since the resin film R is not disposed on the removal side of the glass plate G, the glass plate G can be easily held without being aware of interference (contact) with the resin film R. As a result, the removal operation of each composite 1 from the composite laminate 2A can be simplified.

[0093] Furthermore, the composite laminate 2A placed in the storage container 100 is secured between the pressing part 30 and the back support part 10 by the strap 15a mounted on its front surface, and is held against the back support member 13 by being pressed against the back bearing member 11. Thus, the composite laminate 2A becomes a bundle of composite 1 stacked and stored in the storage container 100 through the protective sheet 3. At this time, the fastening mechanism 15 fastens the composite laminate 2A in such a way that when pulled forward (Z direction) at 50N from the center in the width direction (X direction) of the composite laminate 2A, the displacement α at the traction part is 20mm (see reference). Figure 9 Thus, each composite 1 constituting the composite laminate 2A is pressed against the back support member 11 of the storage container 100 in a stacked state with the protective sheet 3 in between, and is well held in place.

[0094] like Figure 10As shown, in the case of the composite laminate 2A in the state of being a bundled body, when viewed from the direction perpendicular to the main surface (Z direction) of the main surface of the glass plate G of the composite 1, the dimension M between the ends from the end of the glass plate G intersecting with the belt 15a in the fastened position to the nearest end of the resin film R is 5 mm or more and 30 mm or less. Furthermore, when viewed from the direction perpendicular to the main surface (Z direction) of the glass plate G of the composite 1, the average value of the gap distance D between the Nth (N is an integer greater than or equal to 1) glass plate G of the composite 1 and the protective sheet 3 that is in contact with the resin film R disposed on the main surface of the glass plate G of the Nth composite 1, directly below the end of the glass plate G that intersects with the belt 15a at the fastening position, is 20 μm or more, and is less than 80% of the combined thickness of the resin film R before fastening (when there is no stress) and the thickness of the protective sheet 3 before fastening (when there is no stress).

[0095] In this way, the average gap distance D between the plurality of glass plates G of the composite laminate 2A and the protective sheet 3 that is in contact with the resin film R disposed on the main surface of the glass plate G is 20 μm or more, and the composite laminate 2A is fastened with a strength that reduces the distance D to less than 80% of the total thickness of the resin film R and the protective sheet 3. Thus, the composite laminate 2A can be reliably fixed to the back support member 13. Furthermore, when the composite laminate 2A is transported in a bundled state housed in the storage container 100, movement of the composite 1 stacked with the protective sheet 3 in between and contact between the glass plates G with the protective sheet 3 in between can be suppressed. Therefore, deformation, cracking, and defects of the glass plates G can be suppressed.

[0096] Furthermore, in the composite laminate 2A that is in a bundled state, the difference between the maximum value Emax and the minimum value Emin of the distance E between the reference plane Sb, which is perpendicular to the X-axis parallel to the first side G1 of the glass plate G, and the position of the seventh side R7 in the X-axis direction as observed from the reference plane Sb, is less than 10mm (see reference). Figure 7 For example, in the composite laminate 2, the difference between the maximum value Emax and the minimum value Emin of the distance E between the seventh edge R7 of the resin film on the glass plate G furthest from the back support member 13 and the seventh edge R7 of the resin film on other glass plates G is less than 10 mm. Thus, in the case of the composite laminate 2A, even when stored in the bundle of the storage container 100, lateral positional deviation of the composite 1 stacked with the protective sheet 3 can be suppressed. This suppresses stress concentration on the glass plate G caused by lateral displacement of the composite 1.

[0097] As explained above, the bundle of the composite laminate 2A according to the second embodiment can suppress the movement of the composite 1 and the contact between the glass plates G during transportation, thereby suppressing the deformation, cracks and defects of the glass plates G.

[0098] (Third Implementation)

[0099] Next, the packaging body of the composite laminate according to the third embodiment will be described.

[0100] Figure 11 This is a perspective view showing the bundle of the composite laminate according to the third embodiment. The bundle of the composite laminate according to the third embodiment is formed by housing the aforementioned composite laminate 2 or composite laminate 2A (hereinafter referred to as composite laminate 2, 2A) in a storage container 200. Figure 1 Except for the fastening mechanism 41, the fastening mechanism 15 of the storage container 100 shown is the same as that of the storage container 100.

[0101] The fastening mechanism 41 of this structure is provided at two different height positions at both ends of the width direction of the back support member 13. The fastening mechanism 41 is composed of a clamping mechanism, which includes: an engaging member 43 that engages with both ends of the pressing frame 33 in the width direction; and a support portion 45 that supports the engaging member 43 in a manner that allows it to be pulled closer to the back support member 13. The engaging member 43 is, for example, a rod-shaped body with its front end bent into an L-shape, and its front end can press against the pressing frame 33. The support portion 45 is provided on the back support member 13 and supports the engaging member 43 in a manner that allows it to move freely in and out along its length direction. Furthermore, by moving the engaging member 43 in the direction of arrow P, the pressing frame 33 is pressed against the back support portion 10, thereby fastening the composite laminates 2 and 2A provided between the pressing portion 30 and the back support portion 10. In addition, the support portion 45 can release the fastening of the composite laminates 2 and 2A by releasing the engaging member 43.

[0102] The support 45 can be equipped with an actuator such as a motor or cylinder as a drive source, or it can be a one-way clutch or a mechanical locking mechanism using appropriate gears. When using an actuator, drive control is performed via a control unit (not shown) to generate a specified fastening force. Alternatively, when using a mechanical locking mechanism, for example, a mark indicating the movement position where the specified fastening force can be obtained is provided, and the operator manually moves the pressing frame 33 to the position indicated by that mark.

[0103] According to the fastening mechanism 41, a specified fastening force can be generated with simple operation. In addition, it is easy to fix and release the composite laminates 2, 2A to the back support member 13.

[0104] (Fourth Implementation)

[0105] Next, the packaging body of the composite laminate according to the fourth embodiment will be described.

[0106] Figure 12 This is a perspective view showing the bundle of the composite laminate according to the fourth embodiment. The bundle of the composite laminate according to the fourth embodiment is formed by housing the aforementioned composite laminates 2 and 2A in a storage container 300. The storage container 300, in addition to having... Figure 1 Except for the fastening mechanism 51, the fastening mechanism 15 of the storage container 100 shown is the same as that of the storage container 100.

[0107] The fastening mechanism 51 of this structure is composed of an opening and closing lever mechanism, which includes: a rod-shaped lever 53, arranged horizontally across the pressing frame 33; an arm 55, the front end of which is connected to both ends of the lever 53; and a support portion 57, which rotatably supports the base end of the arm 55 to the back support member 13. By rotating the arm 55 about the support portion 57 (as indicated by arrow Q), the lever 53 can be pulled closer to the back support member 10. Furthermore, the lever 53 is positioned near the center of the height of the composite laminates 2 and 2A.

[0108] The support portion 57 can also adopt a structure with an actuator or a mechanical locking mechanism, similar to the support portion 45 in the third embodiment. In either case, a specified fastening force can be generated through simple operation, and the fixing and unfixing of the composite laminates 2, 2A can be easily performed.

[0109] (Fixed position of the composite laminate)

[0110] In the above embodiments, the fastening mechanisms 15, 41, and 51 can be provided only in the central region of the composite laminate 2 and 2A in the vertical direction, or in the upper and lower regions in the vertical direction, or in all of the upper, central, and lower regions, and fasten the composite laminate 2 and 2A at each position.

[0111] Figure 13A , Figure 13B This is an illustrative diagram schematically showing the fastening positions of a composite laminate. For example... Figure 13A As shown, the fastening position can also be centered on the central height H of the composite laminates 2 and 2A, within the width Wa (central region). The width Wa is preferably 80% of the height H of the composite laminates 2 and 2A, more preferably 60%, and even more preferably 50%. Additionally, as... Figure 13BAs shown, the fastening position can also be either from the upper end of the composite laminate 2, 2A within the width Wu (upper region) or from the lower end within the width Wd (lower region). The widths Wu and Wd are preferably 10% of the height H of the composite laminate 2, 2A, more preferably 8%, and even more preferably 5%.

[0113] For the bundles of test examples 1 to 25 with different thicknesses of the second resin film Rb, dimensions of the resin film R, end-to-end dimensions between the glass plate G and the resin film R, and binding forces of the fastening mechanism 15, the gap distance D between the relative surfaces of the glass plates G and the positional offset of the resin film R were measured, and the collapse of the goods after transportation and conveying, damage to the glass plate G, and deformation areas in the first resin film Ra were observed for evaluation.

[0114] Test Examples 1-11 are bundles without the protective sheet 3 (equivalent to the bundles in the first embodiment), and Test Examples 12-25 are bundles with the protective sheet 3 (equivalent to the bundles in the second embodiment). Test Examples 1-19 are based on... Figure 1 The results shown in Test Examples 20-22 are based on the fastening mechanism 15 consisting of belt 15a and tension application part 15b. Figure 12 The results shown in the test examples 23-25 ​​are based on the fastening mechanism 51 using the opening and closing lever mechanism. Figure 11 The results of the fastening mechanism 41 using the clamping mechanism are shown. In addition, test examples 1 to 3, 5 to 6, 10 to 15, 18 to 19, 20, and 23 are examples, and test examples 4, 7 to 9, 16 to 17, 21, 22, 24, and 25 are comparative examples.

[0115] (1) Fabrication of the composite

[0116] Silicone resin is coated on the surface of a resin film made of polyethylene terephthalate (PET, Young's modulus 3.9 MPa), and cured by heating at 140°C for 10 minutes using a heating plate, thereby forming a silicone resin film (thickness 8 μm) on the resin film.

[0117] Next, the resin film on which the silicone resin film is formed is washed with a water-based glass cleaner (PK-LCG213 manufactured by PACCAR Co., Ltd.), and then the resin film is bonded to the main surface of the glass plate G after it has been washed with pure water. Thus, a composite 1 is produced in which a resin film R, in which the silicone resin film is used as the first resin film Ra and the resin film is used as the second resin film Rb, is disposed on the main surface of the glass plate G.

[0118] In addition, the end dimension M from the end of the glass plate G to the end of the resin film R is 5 mm in test examples 1-4, 8-14, and 17-25, and 30 mm in test examples 5-7, 15, and 16.

[0119] Furthermore, the glass plate G is made of alkali-free borosilicate glass with dimensions of 920mm × 730mm and a thickness of 0.5mm (manufactured by AGC Corporation, trade name "AN Wizus", Young's modulus 85 GPa). The coefficient of linear expansion of this glass plate G is 39 × 10⁻⁶. -7 / ℃.

[0120] Next, the prepared composite 1 was placed in an autoclave and heated at 65°C and 1 MPa for 30 minutes to remove the encapsulated air bubbles.

[0121] (2) Bundling of composite laminates

[0122] (2-1) Experimental Examples 1-11

[0123] The 200 composite sheets 1 produced are stacked and stored in the storage container 100, forming a bundle containing the composite stack 2 in the storage container 100.

[0124] As a storage container 100, an iron storage container is used, and a sponge sheet (EVA sheet) is attached to the back support member 11 of the storage container 100, and a foamed polypropylene sheet is attached thereon.

[0125] The composite 1 is placed relative to the storage container 100, with the resin film R in contact with the back support member 11 to which the sponge sheet and the foamed polypropylene sheet are attached. Then, other composites 1 are stacked on top of this composite 1 in sequence, and 200 composites 1 are stacked. At this time, the main surface of the glass plate G of the composite 1 placed in the storage container 100 is in contact with the resin film R of the adjacent composite 1.

[0126] A foamed polypropylene sheet is placed on top of the 200th composite 1, and a plastic corrugated cardboard is placed on top of it. Further, an aluminum pressing frame 33 is placed on top of it.

[0127] Finally, the pressing frame 33, which serves as the fastening mechanism 15, is placed on the front surface of the composite laminate 2 formed by stacking 200 sheets of composite material 1 and fastened by the tension application part 15b to produce a bundle of composite laminate 2.

[0128] In Test Examples 1-7 and Test Examples 10 and 11, the composite laminate 2 was fastened at its center in the width direction by a fastening mechanism 15 such that the displacement at the traction point was 20 mm when traction was applied with 50 N. In Test Examples 8 and 9, the composite laminate 2 was fastened at its center in the width direction by a fastening mechanism 15 such that the displacement at the traction point was 20 mm when traction was applied with 20 N.

[0129] (2-2) Experimental Examples 12-19

[0130] The 200 sheets of composite 1 produced were fitted with a protective sheet 3 (made from virgin pulp backing paper manufactured by Nagara Paper Co., Ltd., with a unit area weight of 50g / m²) on the resin film R side. 2 The composite stacked material 2A is stacked and stored in the storage container 100 in a manner that makes it a bundle containing the composite stacked material 2A in the storage container 100.

[0131] As the storage container 100, an iron storage container is used. Similar to Test Examples 1 to 11, a sponge sheet (EVA sheet) is attached to the back support member 11 of the storage container 100, and a foamed polypropylene sheet is attached thereon.

[0132] Relative to the storage container 100, a protective sheet 3 of the same size as the glass plate G of the composite 1 is placed on the back support member 11, which is fitted with a sponge sheet and a foamed polypropylene sheet, and the composite 1 is placed in such a way that the resin film R contacts the protective sheet 3. Next, the protective sheet 3 is placed on the composite 1, and other composite 1s are overlapped in such a way that the resin film R contacts the protective sheet 3. This layering operation is repeated, and 200 composite 1s are layered with the protective sheets 3 in between.

[0133] A protective sheet 3 and a foamed polypropylene sheet are placed on top of the 200th composite 1, and a plastic corrugated cardboard is placed on top of it. Further, an aluminum pressing frame 33 is placed on top of it.

[0134] Finally, the strap 15a, which serves as the fastening mechanism 15, is placed on the front surface of the composite laminate 2A, which is formed by stacking 200 composite sheets 1 with protective sheet 3, and is fastened by the tension application part 15b to produce a bundle of composite laminate 2A.

[0135] In Test Examples 12-16 and Test Examples 18 and 19, the composite laminate 2A was fastened at its center in the width direction by a fastening mechanism 15 such that the displacement at the traction point was 20 mm when traction was applied with 50 N. In Test Example 17, the composite laminate 2 was fastened at its center in the width direction by a fastening mechanism 15 such that the displacement at the traction point was 20 mm when traction was applied with 20 N.

[0136] (2-3) Experimental Examples 20-22

[0137] The 200 sheets of composite 1 produced were fitted with a protective sheet 3 (made from virgin pulp backing paper manufactured by Nagara Paper Co., Ltd., with a unit area weight of 50g / m²) on the resin film R side. 2 The composite stacked material 2A is stacked and stored in the storage container 300 in a manner that makes it a bundle containing the composite stacked material 2A in the storage container 300.

[0138] As a storage container 300, an iron storage container is used, and a sponge sheet (EVA sheet) is attached to the back support member 11 of the storage container 300, and a foamed polypropylene sheet is attached thereon.

[0139] Relative to the storage container 300, a protective sheet 3 of the same size as the glass plate G of the composite 1 is placed on the back support member 11, which is bonded with a sponge sheet and a foamed polypropylene sheet, and the composite 1 is placed in such a way that the resin film R contacts the protective sheet 3. Next, the protective sheet 3 is placed on the composite 1, and other composite 1s are overlapped in such a way that the resin film R contacts the protective sheet 3. This layering operation is repeated, and 200 composite 1s are layered with the protective sheets 3 in between.

[0140] A protective sheet 3 and a foamed polypropylene sheet are placed on top of the 200th composite 1, and a plastic corrugated cardboard is placed on top of it. Further, an aluminum pressing frame 33 is placed on top of it.

[0141] Finally, the rod 53, which is made of metal rods, is... Figure 12 A pressing frame 33 is arranged on the front surface of a composite laminate 2A consisting of 200 layers of composite 1 separated by protective sheet 3, and the composite laminate 2A is secured by rotating the arm 55 connected to the rod 53 via the support part 57, thus creating a bundle of the composite laminate 2A.

[0142] In test examples 20 and 21, the fastening strength of the support part 57 was set to be relatively strong for fastening, while in test example 22, the fastening strength of the support part 57 was set to be relatively weak for fastening.

[0143] (2-4) Experimental Examples 23-25

[0144] The 200 sheets of composite 1 produced were fitted with a protective sheet 3 (made from virgin pulp backing paper manufactured by Nagara Paper Co., Ltd., with a unit area weight of 50g / m²) on the resin film R side. 2 The composite stacked material 2A is stacked and stored in the storage container 200 in a manner that makes it a bundle containing the composite stacked material 2A in the storage container 200.

[0145] As a storage container 200, an iron storage container is used, and a sponge sheet (EVA sheet) is attached to the back support component 11 of the storage container 200, and a foamed polypropylene sheet is attached thereon.

[0146] Relative to the storage container 200, a protective sheet 3 of the same size as the glass plate G of the composite 1 is placed on the back support member 11, which is fitted with a sponge sheet and a foamed polypropylene sheet, and the composite 1 is placed in such a way that the resin film R contacts the protective sheet 3. Next, the protective sheet 3 is placed on the composite 1, and other composite 1s are overlapped in such a way that the resin film R contacts the protective sheet 3. This layering operation is repeated, and 200 composite 1s are layered with the protective sheets 3 in between.

[0147] A protective sheet 3 and a foamed polypropylene sheet are placed on top of the 200th composite 1, and a plastic corrugated cardboard is placed on top of it. Further, an aluminum pressing frame 33 is placed on top of it.

[0148] Finally, at both ends of the aluminum pressing frame 33, the engaging parts 43 are engaged at the upper and lower parts in the height direction, and the engaging parts 43 are pulled closer toward the back support part 13 to fasten the composite laminate 2A, thus creating a bundle of the composite laminate 2A.

[0149] In test examples 23 and 24, the pulling force of the support portion 45 was increased to set the fastening strength of the composite laminate 2A to be stronger. In test example 25, the pulling force of the support portion 45 was reduced to set the fastening strength of the composite laminate 2A to be weaker.

[0150] (3) Measurement of bundled body

[0151] (3-1) Measurement of the distance between the plates

[0152] When using the storage container 100, a gap gauge (thickness gauge) is inserted directly below the end of the glass plate G that intersects with the strap 15a of the fastening mechanism 15, on the outer periphery of the composite 1 stacked in the storage container 100, when viewed from the vertical direction (Z-axis direction) of the main surface of the glass plate G, to measure the gap distance D. When using the storage container 200, a gauge is inserted directly below the end of the glass plate G that intersects with the engaging member 43 of the fastening mechanism 41 to measure the gap distance D. When using the storage container 300, a gauge is inserted directly below the end of the glass plate G that intersects with the rod 53 of the fastening mechanism 51 to measure the gap distance D. That is, the gap distance D is measured at the fastening position where the maximum fastening force generated by the fastening mechanisms 15, 41, and 51 is applied. Here, the gap distance D is measured every 10 sheets of the composite 1 in the stacking order of the storage container 100, and the average value is calculated.

[0153] Without using the protective sheet 3 in the bundle (Examples 1-11), the gap between the glass plates G of the composite 1 is measured as the gap distance D. With the protective sheet 3 in the bundle (Examples 12-25), the gap between the glass plate G of the composite 1 and the protective sheet 3 is measured as the gap distance D.

[0154] (3-2) Measurement of the positional displacement of the resin film

[0155] The positional offset of the resin film R of the composite 1 stacked in the storage containers 100, 200, and 300 was measured. The positional offset of the resin film R was measured by using the edge of the glass plate G of the foremost composite 1 (the last composite 1 to be mounted) as a reference plane Sb, and measuring the distance E from this reference plane Sb to the end of the resin film R of each composite 1 (refer to...). Figure 7 The distance E of each of the 20 composites 1, stacked in layers of 100, 200, and 300 in the storage containers, was measured every 10 layers. The difference between the maximum value Emax and the minimum value Emin of the 20 composites 1 was taken as the range of the distance E of the resin film R (positional offset of the resin film R).

[0156] (4) Evaluation methods

[0157] (4-1) Evaluation of cargo collapse

[0158] Confirm the position of the end of composite 1 in the bundled package during transport and delivery. If the positional deviation of composite 1 is less than 15mm, it is set as judgment A; if it is more than 15mm, it is set as judgment B. The transport distance is set to at least 350km.

[0159] (4-2) Evaluation of damage, cracks and defects in the composite

[0160] Remove composite 1 from the bundled package after packaging and transport, and visually inspect the outer periphery of composite 1 for damage, cracks, or defects. If no composite 1 has any damage, cracks, or defects, it is classified as criterion A; if more than one composite 1 has damage, cracks, or defects, it is classified as criterion B.

[0161] (4-3) Evaluation of Deformation Zone

[0162] Composite 1 is removed from the bundled package after packaging and transport. A high-brightness light source is irradiated onto composite 1, and a projected image (transmission image) is observed visually. Deformed areas such as depressions and wrinkles in the first resin film Ra are identified from the projected image, and the distance from the end of the resin film R to the deformed area is measured. A determination of S is made when the distance from the end of the resin film R to the deformed area is 5 mm or less; a determination of A is made when the distance is more than 5 mm but less than 10 mm; and a determination of B is made when the distance is more than 10 mm. Furthermore, when forming a device on the first resin film Ra, the deformed area of ​​the first resin film Ra becomes a defective area in device fabrication. Therefore, the deformed area preferably converges to 10 mm or less from the end of the resin film R, and more preferably to 5 mm or less.

[0163] (5) Evaluation Results

[0164] Table 1 shows the bundling conditions, measurement results, and evaluation results for each of the test examples 1 to 25.

[0165] Table 1

[0166]

[0167] (5-1) Evaluation results of cargo collapse

[0168] When the value C, which is the sum of the thickness of the second resin film Rb (value A) and the thickness of the first resin film Ra (value B) multiplied by 0.8 (80%), is compared with the average value of the gap distance D, in Test Examples 1-3, 5-7, 10-16, 18-21, 23, and 24, the average value of the gap distance D is below the value C. In Test Examples 4, 8, 9, 17, 22, and 25, the average value of the gap distance D exceeds the value C. It can be seen that when the average value of the gap distance D is below the value C (Test Examples 1-3, 5-7, 10-16, 18-21, 23, and 24), the evaluation of cargo collapse is graded A, indicating that no cargo collapse occurred. On the other hand, it can be seen that when the average value of the gap distance D exceeds the value C (Test Examples 8, 9, 17, 22, and 25), the evaluation of cargo collapse is graded B, indicating that cargo collapse occurred. In addition, for test example 4, although the average value of the gap distance D exceeded the value of C, the evaluation of the cargo collapse was judged as A.

[0169] (5-2) Evaluation results of damage, cracks and defects in the composite

[0170] In Test Examples 1–3, 5, 6, 8–15, 17–20, 22, 23, and 25, the average gap distance D was 20 μm or more. In Test Examples 4, 7, 16, 21, and 24, the average gap distance D was less than 20 μm. It can be seen that when the average gap distance D is 20 μm or more (Test Examples 1–3, 5, 6, 8–15, 17–20, 22, 23, and 25), the evaluation of damage, cracks, and defects in composite 1 is graded A, indicating no damage occurred. On the other hand, it can be seen that when the average gap distance D is less than 20 μm (Test Examples 4, 7, 16, 21, and 24), the evaluation of damage, cracks, and defects in composite 1 is graded B, indicating damage occurred in composite 1.

[0171] (5-3) Evaluation results of the deformed area

[0172] In Test Examples 1-10, 12-18, and 20-25, the distance E was less than 10 mm, while in Test Examples 11 and 19, the distance E exceeded 10 mm. It can be seen that when the distance E is less than 10 mm (Test Examples 1-10, 12-18, and 20-25), the deformation area of ​​the first resin film Ra is judged as either S or A, and the deformation area of ​​the first resin film Ra is suppressed within a narrow range. On the other hand, it can be seen that when the distance E exceeds 10 mm (Test Examples 11 and 19), the deformation area of ​​the first resin film Ra is judged as B, and a large deformation area is formed in the first resin film Ra.

[0173] Based on the above results, it can be seen that by making the average gap distance D above 20 μm and below C, cargo collapse can be suppressed, and a bundle without damage, cracks, or defects can be obtained. Furthermore, it can be seen that by making the distance E below 10 mm, the deformation area of ​​the first resin film Ra can be suppressed.

[0174] As described above, the present invention is not limited to the above embodiments. Combining the various structures of the embodiments with each other, or making changes and applications based on the description in the specification and well-known technologies by those skilled in the art, are also within the scope of the present invention and are included in the scope of protection claimed.

[0175] As stated above, the following matters are disclosed in this specification.

[0176] (1) A bundle for a composite laminate, supporting the composite laminate in a longitudinal orientation, wherein the composite laminate is formed by stacking multiple composite layers with resin films disposed on the main surface of a glass plate, wherein the bundle for the composite laminate comprises:

[0177] The bottom support portion supports the downward-facing end face of the composite laminate;

[0178] A back support portion supports the back side of the composite laminate in a state in which the main surface of the glass plate is inclined from the vertical direction.

[0179] The pressing part is disposed on the front surface side of the composite laminate opposite to the back side and contacts the surface of the composite laminate.

[0180] A fastening mechanism applies a fastening force to the composite laminate sandwiched between the pressing portion and the back support portion at a fastening position on a portion of the pressing portion.

[0181] The fastening mechanism is provided only in the central region of the composite laminate in the vertical direction, or in both the upper and lower regions in the vertical direction, or in all of the upper, central, and lower regions.

[0182] When the composite laminate is viewed from a direction perpendicular to the main surface of the glass plate, the distance between the ends of the glass plate from the end of the composite laminate in the region corresponding to the fastening position to the nearest end of the resin film is 5 mm or more and 30 mm or less.
