[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0016] Figure 1 It is a front perspective view of the storage container 100 according to the embodiment of the present invention, showing a state in which the plate-like stacked objects 1 are stored. Figure 2 It is a side view of the storage container 100 which concerns on embodiment of this invention. Figure 3 It is a front view of the storage container 100 which concerns on embodiment of this invention.

[0017] like Figure 1~Figure 3 As shown, the plate-shaped object storage container 100 has a storage portion S in which the plate-shaped object stack 1 is stored.

[0018] The plate-like body stack 1 is a stack formed by stacking a plurality of plate-like bodies. In this example, the plate-like body is a glass plate G formed into a rectangular shape when viewed from above, and the storage container 100 stores the plurality of glass plates G in a stacked state. The storage container 100 stores large-sized glass plates G such as the fifth generation size (long side 1,300 mm, short side 1,000 mm), the 5.5th generation size (long side 1,500 mm, short side 1,300 mm), and the sixth generation size (long side 1,850 mm, short side 1,500 mm). The thickness of the glass plate G is, for example, not less than 0.3 mm and not more than 0.7 mm. The storage container 100 in which a plurality of such large-sized glass plates G are stacked and stored is loaded on a cargo bed of a transport vehicle (e.g., a trailer or a truck) and transported.

[0019] The glass plate G is made of an alkali-free glass material used in a flat panel display (FPD: Flat Panel Display) such as LCD (Liquid Crystal Display) or OLED (Organic Light-Emitting Diode), for example.

[0020] Figure 4 It is a side view of the plate-shaped stacked product 1 in which the glass plates G are stacked and stored in the storage container 100 .

[0021] like Figure 4 As shown, the glass sheets G are stacked one on top of the other via the paper 2. The paper 2 is formed into a rectangular shape having a larger area than the glass sheets G. Thus, the paper 2 is interposed between the glass sheets G so that its edge portion protrudes from the edge portion of the glass sheets G.

[0022] like Figure 1~Figure 3 As shown, the storage container 100 is mainly composed of a base 110, a bottom plate 120 and a back plate 130. The bottom plate 120 and the back plate 130 are arranged on the top of the base 110. The bottom plate 120 supports the lower edge of the plate-like stacked object 1, and the back plate 130 supports the main surface of the plate-like stacked object 1.

[0023] The upper surface of the base 110 is a flat placement surface 111. The front surface, rear surface, and both side surfaces of the base 110 are provided with openings 112 for inserting and removing claws (not shown) of a forklift.

[0024] Figure 5 This is an exploded perspective view of the pedestal 110 viewed from the back side of the storage container 100 according to the embodiment of the present invention.

[0025] like Figure 5As shown, the pedestal 110 is formed by, for example, joining a plurality of steel plates subjected to stamping. The pedestal 110 includes an upper plate portion 113 constituting a mounting surface 111, a bottom plate portion 115 constituting a bottom surface in contact with the ground, a vertical plate portion 116 located between the upper plate portion 113 and the bottom plate portion 115, and a side plate portion 117 constituting a peripheral surface. In addition, a plurality of reinforcement members 118 are provided on the pedestal 110 at intervals in the insertion and extraction direction of the claw of a forklift inserted and extracted into the opening 112. These reinforcement members 118 are formed, for example, in a C-shaped cross-sectional view, arranged in a direction orthogonal to the insertion and extraction direction of the claw of the forklift, and fixed to the bottom plate portion 115 and the vertical plate portion 116 by welding. Thus, the pedestal 110 is reinforced by the reinforcement members 118, and in particular, deformation of the opening 112 when transported by a forklift or the like is suppressed.

[0026] like Figure 1~Figure 3 As shown, the bottom plate 120 is supported by a beam 121 on the upper surface of a support plate 122 fixed to the upper portion of the mounting surface 111 of the pedestal 110. The bottom plate 120 is arranged to be inclined relative to the mounting surface 111 of the pedestal 110. The bottom plate 120 carries the lower edge of the plate-like body stack 1 on the upper surface side. A buffer member 123 is attached to the upper surface of the bottom plate 120.

[0027] The back plate 130 is supported on the upper part of the mounting surface 111 of the pedestal 110 by the frame member 131. The back plate 130 is erected and inclined relative to the mounting surface 111 of the pedestal 110. The main surface of the glass plate G of the plate-like body laminate 1 is overlapped on the front surface side of the back plate 130. A buffer member 133 is attached to the front surface of the back plate 130.

[0028] Figure 6 It is a perspective view for explaining the structure of the frame member 131 of the storage container 100 according to the embodiment of the present invention.

[0029] like Figure 6 As shown, the frame member 131 has a plurality of (five in this example) support plates 134. The support plates 134 are arranged at intervals in the width direction of the storage container 100, and are fixed and erected on the mounting surface 111 of the pedestal 110, respectively.

[0030] The support plate 134 is made of, for example, a steel plate and is formed into a substantially triangular shape. The support plate 134 has: a bottom side portion 134a fixed to the mounting surface 111 of the pedestal 110; a vertical side portion 134b extending vertically upward from the bottom side portion 134a; and an inclined side portion 134c connecting the end of the bottom side portion 134a and the end of the vertical side portion 134b. These bottom side portions 134a, the vertical side portions 134b, and the inclined side portions 134c are formed by bending the edge portion of the support plate 134. A plurality of holes 134d are formed on the support plate 134 for the purpose of weight reduction. In addition, between the holes 134d of the support plate 134, a reinforcement member 135 formed into a C-shaped cross-section is fixed, for example, by welding. And the support plate 134 is reinforced by these reinforcement members 135. Furthermore, when the storage container 100 is viewed from the front, the two support plates 134 on the right side and the three support plates 134 on the left side are formed in a bilaterally symmetrical shape.

[0031] The back plate 130 is attached to the inclined side portions 134 c of the plurality of support plates 134 . Thus, the back plate 130 is erected and inclined with respect to the mounting surface 111 of the pedestal 110 .

[0032] In the storage container 100, the bottom plate 120 on which the lower edge of the plate-like body stack 1 is placed and the back plate 130 on which the main surface of the glass plate G of the plate-like body stack 1 is supported form an angle of 90° or approximately 90°. Furthermore, the lower edge of the plate-like body stack 1 is supported by the bottom plate 120, and the main surface of the glass plate G is supported by the back plate 130, so that the plate-like body stack 1 is stored in a tilted standing state in the storage container 100. In this way, in the storage container 100, the storage section S is formed by the bottom plate 120 and the back plate 130, and the plate-like body stack 1 is stored in the storage section S.

[0033] like Figure 1 As shown, in the storage container 100, the plate-like stacked objects 1 are stored in a state of being tilted and standing in a storage portion S, and the storage portion S is formed by a bottom plate 120 and a back plate 130. In this storage state, in the storage container 100, a white protective plate 150, for example, made of resin, is overlapped on the front surface side of the stored plate-like stacked objects 1. In addition, a front surface pressing frame 151 is arranged on the front surface side of the protective plate 150.

[0034] The front surface pressing frame 151 is a member formed by connecting a plurality of square pieces 152 along the longitudinal and lateral directions in a lattice shape. As the square pieces 152, square pieces made of aluminum are used.

[0035] A plurality of (eight in this example) handles 153 are installed on the front surface side of the front surface pressing frame 151. The handles 153 are provided on the longitudinal square member 152 constituting the front surface pressing frame 151. Three handles 153 are installed at equal intervals along the long side direction on the two longitudinal square members 152 constituting the side of the front surface pressing frame 151. A handle 153 is installed at the center of each of the two longitudinal square members 152 near the center of the front surface pressing frame 151 in the longitudinal direction. These handles 153 are components formed by forming a metal rod into a C-shape in side view, and are fixed to the square member 152, for example, by screwing. The front surface pressing frame 151 equipped with a plurality of handles 153 can be easily carried and disassembled from the storage container 100 by holding the handles 153.

[0036] A plurality of (three in this example) belts 155 are hung on the storage container 100, and the storage container 100 overlaps the protective plate 150 and the front surface pressing frame 151 on the front surface side of the plate-like body stack 1. As these belts 155, binding belts can be used. One end of each of these belts 155 is fixed to a fastener 156 such as an eye bolt or a buckle provided on one side of the frame member 131. In addition, these belts 155 pass through the gap between the handle 153 of the front surface pressing frame 151 and the square member 152, and the other end thereof is pulled and fixed by a ratchet (not shown) provided on the other side of the frame member 131. Thus, the belt 155 is hung in front of the front surface pressing frame 151 while being restrained from falling off by the handle 153.

[0037] Then, by pulling and fixing the belt 155 with the ratchet, the plate-like stack 1, the protection plate 150, and the front surface pressing frame 151 are fastened by the belt 155. Therefore, the plate-like stack 1 is pressed against the back plate 130 by the front surface pressing frame 151 via the protection plate 150, and is stored in the storage container 100 in a state where the movement is restricted. Thus, even during transportation, the positional deviation of the stored plate-like stack 1 can be suppressed.

[0038] As described above, according to the storage container 100 of the above embodiment, since the back plate 130 is supported on the pedestal 110 by the plurality of support plates 134, it can be manufactured more easily than a structure in which the back plate 130 is supported by a frame member formed by welding and joining a plurality of steel materials to each other. In addition, it is possible to achieve weight reduction.

[0039] In addition, the present invention can be applied as a storage container for electronic devices other than LCD, OLED, and FPD, such as glass substrates for optical elements, glass disks, solar cells, and other plate-like bodies. In addition, the plate-like body to be stored is not limited to glass plates, and can also be formed of metal, ceramics, or resin, for example.

[0040] Thus, the present invention is not limited to the above-mentioned embodiments, and combining the structures of the embodiments with each other, and changing and applying them by those skilled in the art based on the description in the specification and known technologies are also the intended contents of the present invention and are included in the scope of the protection required.

[0041] As described above, the following matters are disclosed in this specification.

[0042] (1) A storage container for plate-like bodies for storing a plurality of plate-like bodies in an inclined stacked state, wherein the storage container for plate-like bodies comprises: a base; a bottom plate, which is arranged on the base and supports the lower edge of the plate-like bodies; and a back plate, which is arranged on the base and supports the main surface of the plate-like bodies, wherein the back plate is supported by a plurality of support plates, and the plurality of support plates are arranged on the base at intervals from each other.

[0043] The plate-shaped storage container of this structure has a structure in which the back plate is supported on a pedestal by a plurality of support plates. Therefore, it can be easily manufactured and lightweight compared to a structure in which the back plate is supported by a frame member formed by welding and joining a plurality of steel materials to each other.
