Description

Technical Field

[0001] The present invention relates to a storage container for a glass plate. Background Art

[0002] In recent years, there has been an increasing demand for larger glass plates used in flat panel displays (FPDs) such as LCDs (Liquid Crystal Displays) and OLEDs (Organic Light-Emitting Diodes). In order to prevent defects such as chipping and cracking of the stored glass plates due to movement during transportation, the glass plates stacked in the storage container are required to be transported stably without moving.

[0003] As a storage container for stacking and storing glass plates, as described in Patent Document 1, there is a storage container including a bottom plate for receiving lower edges of the stacked glass plates and a back plate for receiving main surfaces of the glass plates.

[0004] In the storage container described in Patent Document 1, the base 18 is formed by welding a plurality of long and short steel materials in the longitudinal, transverse and height directions, and the mounting surface 16 is machined (grinded) to a predetermined flatness after welding and assembly.

[0005] In the storage container described in Patent Document 1, the base 18 is formed of a plurality of long and short steel members, namely, frame members.

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0021] (First Embodiment)

[0022] like Figure 1 and Figure 2 As shown, the glass plate storage container 100 stores a glass plate stack 103 .

[0023] 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.

[0024] 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.

[0025] 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).

[0026] 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.

[0027] The end surface support portion 125 has a buffer 126 in a region in contact with the end surface of the glass plate. 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] The lateral pressing portion 109 includes a pressing plate 112 and a handle 111. By rotating the handle 111, 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.

[0032] 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.

[0033] The chassis 107 includes a frame 135 formed by joining a plurality of frame members 129 in the longitudinal, transverse and height directions; a side cover member 123 attached to the side surface of the frame 135 ; and a plate 119 provided on the lower surface of the frame 135 .

[0034] A side cover member 123a is attached to the side of the long side of the frame 135, and a side cover member 123b is attached to the side of the short side. The side cover member 123 is attached so that an opening 121 for inserting and removing a forklift claw (not shown) is provided on the side of the base 107. That is, a pair of openings 121 for inserting and removing a forklift claw (not shown) are formed on each of the four side surfaces of the base 107.

[0035] The base 107 has a plate 119 provided on 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 attached to the frame 135 using bolts and nuts. Figure 6 The bottom view shows a state where the plate 119 is removed, and the shaded area indicates the area that contacts the ground when the frame 135 is placed on the ground. When the plate 119 is provided on the lower surface of the frame 135, the plate 119 contacts the shaded area of ​​the frame 135.

[0036] like Figure 6 As shown, the frame body 135 is formed by joining a plurality of frame members 129 in the longitudinal, transverse and height directions, and therefore, a gap 133 defined by the frame members 129 exists on the lower surface of the frame body 135 .

[0037] Here, the gaps 133 defined by the frame member 129 on the lower surface of the frame 135 are gaps defined by the frame member 129 that abuts against the ground when the frame 135 is placed on the ground. That is, in the storage container of the first embodiment, the number of gaps 133 present on the lower surface of the frame 135 is 12.

[0038] The plate 119 is provided so as to cover the gaps 133 existing on the lower surface of the frame 135. The plate 119 only needs to cover at least one of the gaps 133. The rollers of the roller conveyor may be hooked on the frame member 129 that defines a specific gap 133 at a high frequency. In such a case, only the gaps 133 defined by the frame member 129 that is likely to be hooked may be covered with the plate 119, and the other gaps 133 may not be covered with the plate 119.

[0039] The plate 119 is preferably made of stainless steel. Since the plate 119 contacts the ground, by making it of 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] (Second Embodiment)

[0042] Next, a glass plate storage container 200 according to a second embodiment is described. The storage container 200 according to the second embodiment is different from the storage container 100 according to the first embodiment in at least the structure of the back plate support portion 208 and the frame 235 that support the back plate 210. In the following, only the differences from the first embodiment are described, and the description of the common elements is omitted.

[0043] In the case of the storage container 200 , for example, a large-sized glass plate G of the fifth generation size (long side 1300 mm, short side 1100 mm) is stored.

[0044] The back plate 210 is supported by a plurality of (five in this example) back plate support portions 208a, 208b, 208c, 208d, and 208e (see Figure 7 ). A plurality of (three in this example) belt mounting portions 218 are provided on the side of the back plate support portion 208a of the back plate support portion 208 supporting the back plate 210, and a plurality of (three in this example) ratchets 214 are provided on the side of the back plate support portion 208e (see Figure 8 ).

[0045] A plurality of straps (not shown) are hung on the storage container 200 on which the glass plate stack 203 is placed. As these straps, binding straps can be used. One end of these straps is fixed to the strap attachment portion 218 of the back plate support portion 208a via a hook (not shown). In addition, these straps are pulled and fixed by the ratchet 214 provided on the back plate support portion 208e through the front surface side of the glass plate stack 203.

[0046] The plurality of back plate support parts 208 are each formed of a single member. In other words, the back plate support parts 208 are formed by cutting, bending or welding a metal plate.

[0047] like Fig.10 As shown, the base 207 has a plate 219 disposed on the lower surface of the frame 235 . Fig.11 This is a bottom view of the storage container 200 in a state where the plate 219 provided on the lower surface of the frame 235 is removed, and the oblique line area represents the area that contacts the ground when the frame 235 is placed on the ground. Therefore, in the storage container of the second embodiment, the number of gaps 233 divided by the frame member 229 on the lower surface of the frame 235 is 15.

[0048] 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 plates, solar cells, and other glass plates. In addition, the glass plates to be stored are not limited to glass plates, and can also be formed of metal, ceramics, or resins.

[0049] Thus, the present invention is not limited to the above-mentioned embodiments, and combining the structures of the embodiments with each other, and making changes and applications 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.
