[0014] Description of symbols 100 Storage Containers 103 Glass plate laminate 107 base 109 horizontal pressure part 110 back panel 120 horizontal pressure parts 128 base plate G Glass Plate DETAILED DESCRIPTION

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

[0016] like Figure 1 and Figure 2 As shown, the glass plate storage container 100 stores a glass plate stack 103 .

[0017] The glass plate stack 103 is a stacked product formed by stacking a plurality of glass plates. The glass plate 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, for example, a large-sized glass plate G of the sixth generation size (long side 1850 mm, short side 1500 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 platform of a transport vehicle (e.g., a trailer or a truck) and transported.

[0018] like Figure 4 As shown, the glass plates G are stacked one on top of the other with the paper 102 interposed therebetween. The paper 102 is formed in a rectangular shape having a larger area than the glass plates G. Thus, the paper 102 is interposed between the glass plates G so that its edge portion protrudes from the edge portion of the glass plates G.

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

[0020] like Figure 1~Figure 3 As shown, the storage container 100 is mainly composed of a base 107, a placing portion 105, a horizontal pressing portion 109, and an end surface supporting portion 125. The placing portion 105, the horizontal pressing portion 109, and the end surface supporting portion 125 are arranged on the upper portion of the base 107. The end surface supporting portion 125 supports the lower edge of the glass plate stack 103, and the placing portion 105 supports the main surface of the glass plate stack 103. The horizontal pressing portion 109 is arranged on both end sides of the end surface supporting portion 125 on the base 107 to press the two side edges of the glass plate stack 103.

[0021] The end surface support portion 125 has a buffer 126 in a region in contact with the end surface of the glass plate G. The buffer 126 is attached to the bottom plate 128 by a double-sided adhesive tape or an adhesive material. The end surface support portion 125 is arranged obliquely with respect to the mounting surface 117 of the base 107. The upper surface side of the end surface support portion 125 is provided with the buffer 126, and the lower edge of the glass plate laminate 103 is placed on the buffer 126.

[0022] The mounting portion 105 is provided at a predetermined angle on the mounting surface 117 of the base 107. The mounting portion 105 includes a back plate support portion 108, a back plate 110 mounted on the back plate support portion 108, and a buffer member 106 attached to the back plate 110 by a double-sided adhesive tape or an adhesive material. The front surface side of the mounting portion 105 is provided as the buffer member 106, and the main surface of the glass plate G of the glass plate laminate 103 overlaps with the buffer member 106. The back plate 110 is formed by combining a plurality of (five in this example) back plate small pieces.

[0023] The back plate support 108 is provided with a reinforcement 115. The reinforcement 115 is a columnar member connecting the back plate support 108 to the mounting surface 117 of the base 107, and is provided at a predetermined angle relative to the vertical direction. Figure 2 There are multiple (five in this example) ones arranged in the depth direction.

[0024] A label plate 113 is erected on the upper portion of the mounting surface 117 (see Figure 1 ). The label plate 113 has a label attached to its surface. A barcode, QR code, etc. are displayed on the label, and by reading these codes, information of the glass plate laminate 103, such as the number of glass plates G and thickness, can be read.

[0025] The horizontal pressing part 109 includes a horizontal pressing member 120 having a pressing plate 112 and a handle 111. In the horizontal pressing part 109, by rotating the handle 111 of the horizontal pressing member 120, the pressing plate 112 moves toward the side edge of the glass plate stack 103 stored in the storage container 100. Thus, the pressing plate 112 is pressed against the side edge of the glass plate stack 103, and the lateral deviation of the glass plate stack 103 stored in the storage container 100 is suppressed.

[0026] Furthermore, by rotating the handle 111 in the reverse direction, the pressing plate 112 moves in a direction away from the side edge of the glass plate stack 103 , and the pressing of the side edge of the glass plate stack 103 by the pressing plate 112 is released.

[0027] like Figure 5 As shown, the base 107 includes a frame 135, which is formed by joining a plurality of frame members 129 in the vertical, horizontal, and height directions. When the storage container 100 is placed on the ground, the frame 135 Figure 5 The oblique line area in the figure contacts the ground.

[0028] like Figure 1~Figure 3As shown in the figure, a side cover member 123a is installed on the side of the long side of the frame 135, and a side cover member 123b is installed on the side of the short side of the frame 135. The side cover members 123a and 123b are installed in a manner that an opening 121 for inserting and removing a claw (not shown) of a forklift is provided on the side of the base 107. That is, a pair of openings 121 for inserting and removing a claw (not shown) of a forklift are formed on each of the four side surfaces of the base 107.

[0029] like Figure 6 As shown, the lateral pressing member 120 of the lateral pressing portion 109 has a support plate 143. The support plate 143 is rotatably mounted on the upper portion of a support stand 141 fixed to the base 107 via a pair of hinges 142. The pressing plate 112 and the handle 111 are provided on the support plate 143.

[0030] The handle 111 has a screw 145 rotatably connected to the back of the pressing plate 112, and the screw 145 is screwed into an internal thread portion (not shown) provided on the support plate 143. Thus, by rotating the handle 111, the pressing plate 112 moves in a direction approaching or moving away from the side edge of the glass plate stack 103 stored in the storage container 100. In addition, the pressing plate 112 has guide pins 112a on both sides of the screw 145, and the guide pins 112a are inserted into guide holes 143a formed in the guide support plate 143. Thus, when the pressing plate 112 moves in a direction approaching or moving away from the side edge of the glass plate stack 103, it is guided by the guide pins 112a inserted into the guide holes 143a.

[0031] In addition, the horizontal pressure part 109 has a locking member 157 on the upper part of the support platform 141, and the locking member 157 is locked and disengaged from the pin 150 of the support plate 143 provided on the horizontal pressure member 120. The locking member 157 maintains the support plate 143 in a vertical configuration by locking the pin 150. The locking member 157 is provided with an operating rod 158, and the operating rod 158 has a ring 158a at the end. By pulling the ring 158a of the operating rod 158, the locking state of the pin 150 is released. And, in the state where the locking state of the pin 150 of the support plate 143 by the locking member 157 is released, when the support plate 143 is rotated, the horizontal pressure member 120 moves in a direction away from the two end positions of the bottom plate 128.

[0032] In the horizontal pressing part 109, the rotating horizontal pressing member 120 is rotated in the opposite direction, so that the pin 150 of the locking plate 143 is locked to the locking member 157, and the support plate 143 is arranged vertically.

[0033] Thus, in the storage container 100, the horizontal pressing member 120 can be moved in a direction away from the two end positions of the bottom plate 128. Therefore, by moving the horizontal pressing member 120 in a direction away from the two end positions of the bottom plate 128, when the glass sheet G is stored in the storage container 100 or when the glass sheet G is taken out of the storage container 100, the horizontal pressing member 120 does not hinder the storage operation or the taking-out operation, and the storage operation or the taking-out operation can be performed smoothly.

[0034] like Figure 7 As shown, in the horizontal pressing part 109, the horizontal pressing member 120 can be installed and removed relative to the support platform 141 on the base 107. The hinge 142 that rotatably mounts the horizontal pressing member 120 relative to the support platform 141 includes a fixed hinge part 151 fixed to the support platform 141 and a movable hinge part 155 fixed to the support plate 143 of the horizontal pressing member 120. The fixed hinge part 151 has a rotating pin 153 that can be inserted and pulled out relative to an engagement hole (not shown) formed in the movable hinge part 155. The movable hinge part 155 is rotatably connected to the fixed hinge part 151 in a state where the rotating pin 153 of the fixed hinge part 151 is inserted into the engagement hole. In addition, the movable hinge part 155 can be separated from the fixed hinge part 151 by pulling out the rotating pin 153 of the fixed hinge part 151 from the engagement hole. Then, by separating the movable hinge portion 155 from the fixed hinge portion 151 , the horizontal pressing member 120 is removed from the support stand 141 .

[0035] like Figure 8 As shown, the storage container 100 has a horizontal pressure member holding portion 161, which can hold the horizontal pressure member 120 removed from the horizontal pressure member 109. The horizontal pressure member holding portion 161 is provided on both sides of the base 107, and is respectively arranged behind the back plate 110 deviated from the storage position of the glass plate stack 103 in the storage container 100.

[0036] The horizontal pressure member holding portion 161 includes a pair of holding plates 162 erected on the mounting surface 117 of the base 107, and these holding plates 162 are arranged in a manner opposite to each other. These holding plates 162 have slits 163 at their front ends. The horizontal pressure portion 109 is held on the holding plates 162 by inserting the support plate 143 into the slits 163 of the pair of holding plates 162.

[0037] In this way, the storage container 100 can hold the horizontal pressing member 120 removed from the horizontal pressing portion 109 in the horizontal pressing member holding portion 161 provided on the base 107. This can avoid the loss of the removed horizontal pressing member 120 and the unfavorable situation that the removed horizontal pressing member 120 interferes with other operations.

[0038] In addition, if Figure 5As shown, the frame 135 of the base 107 is formed by joining a plurality of frame members 129 in the longitudinal, transverse and height directions. Therefore, there are gaps 133 divided by the frame members 129 on the lower surface of the frame 135. The gaps 133 divided by the frame members 129 on the lower surface of the frame 135 refer to gaps divided by the frame members 129 that abut against the ground when the frame 135 is placed on the ground. That is, in the storage container 100 of the above-mentioned embodiment, the number of gaps 133 present on the lower surface of the frame 135 is 12. In the base 107 having such gaps 133, there is a case where the rollers of the roller conveyor are hooked on the frame members 129 that divide specific gaps 133.

[0039] Fig. 9 107 shows another structural example. Fig. 9 As shown, the base 107 of another structural example has a plate 119 covering the bottom surface of the frame 135. The plate 119 is formed by combining a plurality of (two in this example) small pieces and is mounted on the bottom surface of the frame 135 using bolts and nuts. Thus, in the base 107, the plate 119 abuts against the ground. The plate 119 is preferably made of stainless steel. Since the plate 119 abuts against the ground, by making it stainless steel, the durability can be improved and damage to the plate 119 can be suppressed.

[0040] In addition, the plate 119 has an opening 131 for moving the storage container 100 by a manual lift (Pallet Truck). When the storage container 100 is moved by the manual lift, the claws of the manual lift are inserted into a pair of openings 121 provided on the side surface of the long side of the base 107. At this time, the wheels provided at the front end of the claws of the manual lift are located in the openings 131, and the wheels are in contact with the ground. Thus, the storage container 100 can be moved by the manual lift.

[0041] In this way, by installing the plate 119 on the bottom surface of the frame 135 of the base 107, the gap 133 can be covered, and the roller of the roller conveyor can be prevented from being hooked on the frame member 129. It should be noted that the plate 119 can be used to cover only the gap 133 divided by the frame member 129 where the roller of the roller conveyor is likely to be hooked, and the plate 119 can be used to not cover the other gaps 133.

[0042] It should be noted that the present invention can be used 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 glass plates. In addition, the storage container 100 is not limited to glass plates, and can also be used to store plate-like bodies formed of metal, ceramics, or resins.

[0043] 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.

[0046] According to the glass plate storage container, the horizontal pressing member can move in a direction away from the two end positions of the bottom plate. Therefore, by moving the horizontal pressing member in a direction away from the two end positions of the bottom plate, when the glass plate is stored in the storage container or taken out of the storage container, the horizontal pressing member does not hinder the storage operation or the taking out operation, and the storage operation or the taking out operation can be performed smoothly.
