Description

Technical Field

[0001] The present invention relates to a plate-shaped storage container. Background Art

[0002] In recent years, there has been an increasing demand for larger glass substrates for FPD (Flat Panel Display), such as glass substrates for liquid crystal displays and plasma displays. In order to prevent defects such as cracks and breakages caused by movement of the stored glass plates during transportation, the storage containers used to store / transport such large glass plates require that the glass plates stacked on the base of the storage container can be transported stably without moving.

[0003] As a storage container for stacking and storing such glass plates, there is known a storage container including a bottom plate for receiving the lower edges of the stacked glass plates and a back plate for receiving the main surfaces of the glass plates (for example, see Patent Document 1).

[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, in a state where 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 loading surface 111. The base 110 is formed by joining a plurality of long and short steel materials in the longitudinal, transverse and height directions. In addition, openings 112 for inserting and removing claws (not shown) of a forklift are formed on the front and rear surfaces of the base 110.

[0024] The bottom plate 120 is fixed and supported on the upper part of the mounting surface 111 of the pedestal 110 by beams 121. The bottom plate 120 is arranged to be inclined relative to the mounting surface 111 of the pedestal 110. The lower edge of the plate-like body stack 1 is placed on the upper surface side of the bottom plate 120. A cushioning member 123 is attached to the upper surface of the bottom plate 120.

[0025] 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.

[0026] The frame member 131 includes a plurality of support plates 134. The support plates 134 are arranged at intervals in the width direction of the storage container 100, and are fixed to and erected on the mounting surface 111 of the pedestal 110, respectively.

[0027] The support plate 134 is made of, for example, a steel plate and is formed into a roughly 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. A plurality of holes 134d are formed on the support plate 134 for the purpose of weight reduction. In addition, a reinforcement member 135 formed into a C-shaped cross-section is fixed to the support plate 134, for example, by welding. And the support plate 134 is reinforced by these reinforcement members 135.

[0028] The back plate 130 is attached to the inclined side portions 134c of the plurality of support plates 134. Thus, the back plate 130 is erected and inclined relative to the mounting surface 111 of the pedestal 110. In addition, a back plate 136 is provided on the back side of the frame member 131, and the back plate 136 is erected on the mounting surface 111 of the pedestal 110, and the back plate 136 is fixed to the vertical side portions 134b of each support plate 134 of the frame member 131.

[0029] 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.

[0030] Figure 5 yes Figure 2 Enlarged view of part A in .

[0031] like Figure 5As shown, the end surface 130a of the lower end of the back plate 130 abuts against the upper surface side of the bottom plate 120. Moreover, the lower end position P of the end surface 120a of the bottom plate 120 is arranged below the placement surface 111 of the pedestal 110. As a result, the position of the storage portion S of the glass plate G formed by the bottom plate 120 and the back plate 130 is lowered.

[0032] like Figure 1 As shown, in the storage container 100, the plate-like stacked objects 1 are stored in a storage portion S in a tilted standing state, 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 140, for example, made of resin is overlapped on the front surface side of the stored plate-like stacked objects 1, and further, corner contact parts 141 made of resin are attached to each corner of the front side of the plate-like stacked objects 1.

[0033] The plate-like body stack 1, on which the protection plate 140 is superimposed and the corner contact member 141 is attached to the corner, is held in the storage container 100 by a plurality of (two in this example) straps 145 hung on the front surface side. A binding strap can be used as the strap 145. One end of the strap 145 is fixed to a fastener 146 such as an eye bolt or a buckle provided on one side of the frame member 131, and the other end is pulled and fixed by a ratchet (not shown) provided on the other side of the frame member 131.

[0034] Then, the plate-like stack 1 and the protection plate 140 are fastened by the belt 145 by pulling and fixing the belt 145 with the ratchet. Therefore, the plate-like stack 1 is pressed against the back plate 130 via the protection plate 140 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.

[0035] Figure 6 This is a front perspective view of the storage container 100 according to the embodiment of the present invention, in a state where the housing 150 is attached.

[0036] like Figure 6 As shown, the housing 150 can be installed in the storage container 100. The housing 150 is formed into a box shape, and the box shape has a front surface plate 151, an upper surface plate 152 and a side panel 153, and is assembled on the base 110 in a manner of covering the storage container 100 from the front and top. When the housing 150 is assembled to the storage container 100, the edges of the upper surface plate 152 and the rear side of the side panel 153 of the housing 150 are along the upper edge and the side edge of the back panel 136 without a gap. In addition, by assembling the housing 150 to the storage container 100, the outer periphery of the storage container 100 is covered by the housing 150 and the back panel 136, so that the plate-like body stack 1 stored is protected and the attachment of garbage and dust to the plate-like body stack 1 is suppressed.

[0037] As described above, according to the storage container 100 of the above embodiment, the lower end position P of the bottom plate 120 is arranged at a position lower than the placement surface 111 of the pedestal 110. As a result, the position of the storage portion S of the glass plate G formed by the bottom plate 120 and the back plate 130 can be lowered to suppress the overall height dimension of the storage container 100. In addition, since the overall height is suppressed, glass plates G of a larger size can be stacked and stored.

[0038] In addition, in the above-mentioned storage container 100, a structure may be adopted in which the end surface 120a of the bottom plate 120 is in contact with the front surface side of the back plate 130. In this case, by arranging the lower end position of the back plate 130 at a position lower than the placement surface 111 of the pedestal 110, the position of the storage portion S of the glass plate G formed by the bottom plate 120 and the back plate 130 is lowered. In addition, the lower end positions of the bottom plate 120 and the back plate 130 may be arranged at a position lower than the placement surface 111 of the pedestal 110.

[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 disposed on the base and supporting the lower edge of the plate-like bodies; and a back plate disposed on the base and supporting the main surface of the plate-like bodies, wherein the lower end position of at least one of the bottom plate and the back plate is arranged at a position lower than the upper surface of the base.

[0043] According to the storage container of the plate-like body of this structure, the position of the storage part of the plate-like body formed by the bottom plate and the back plate can be lowered to suppress the overall height dimension. In addition, since the overall height can be suppressed, it is possible to stack and store plate-like bodies of larger size.
