  The support bars 14B and 14C are arranged in a vertical direction and in parallel, with upper and lower ends connected to a pair of upper and lower beams 22C and 24C arranged above and below the frame structure 12. In addition, the support bars 14B and 14C are connected at their upper and lower ends at arbitrary positions selected in the longitudinal direction of the upper beam 22C and the lower beam 24C by a position adjusting unit described later. That is, like the support bars 14A and 14D, the support bars 14B and 14C are connected to the upper beam 22C and the lower beam 24C so that the horizontal interval can be adjusted according to the size of the glass plate G.

  Since the position adjusters of the support bars 14A and 14D and the position adjusters of the support bars 14B and 14C have the same configuration, the position adjusters of the support bars 14A and 14D will be described here.

  As shown in FIG. 2, the position adjusting portion is provided along a longitudinal direction of a plurality of (three in FIG. 2) long holes 28A, 28B, and 28C provided along the longitudinal direction of the upper beam 22A and the lower beam 24A.

<Sidebars 16A-16H>
The side bars 16 </ b> A to 16 </ b> D are arranged in the horizontal direction with left and right ends attached to a pair of support bars 14 </ b> A and 14 </ b> B that face each other in the frame structure 12. Further, the side bars 16A to 16D are arranged in parallel vertically with a predetermined interval.

  Similarly, the side bars 16E to 16H are arranged in the horizontal direction with left and right ends attached to a pair of opposing support bars 14C and 14D. Further, the side bar 16E is disposed at a position facing the side bar 16A in the horizontal direction, and similarly, the side bars 16F to 16H are also disposed at positions facing the side bars 16B to 16D in the horizontal direction.

  Since the attachment form of the side bars 16A to 16D to the support bars 14A and 14B and the attachment form of the side bars 16E to 16H to the support bars 14C and 14D are the same, the attachment form of the side bar 16A to the support bars 14A and 14B is here. Will be explained.

  FIG. 3A is a cross-sectional view of a main part showing a mounting form of the side bar 16A to the support bar 14A, and FIG. 4A is a cross-sectional view of a main part showing a mounting form of the side bar 16A to the support bar 14B. FIG.

  As shown in FIG. 3A, a bracket 36 having an L-shaped cross section is provided on the support bar 14A in the horizontal direction, and the left end portion of the side bar 16A (see FIG. 1) is a bolt 38 and a nut. 40 is fixed. That is, the left end portion of the side bar 16A is configured as a fixed end. The bolt 38 is inserted into the through hole 42 at the left end of the side bar 16 </ b> A and the long hole 44 of the bracket 36 and fastened to the nut 40.

  As shown in the plan view of the bracket 36 shown in FIG. 3B, the long hole 44 is opened along the longitudinal direction of the bracket 36, that is, the longitudinal direction of the side bar 16A. The fixing position of the side bar 16 </ b> A by the bolt 38 and the nut 40 is selected within the range of the length of the long hole 44 in the longitudinal direction. Thereby, the horizontal position of the side bar 16 </ b> A with respect to the support bar 14 </ b> A is adjusted within the range of the length of the long hole 44 in the longitudinal direction.

  As shown in FIG. 4A, a bracket 46 having an L-shaped cross section is provided on the support bar 14B in the horizontal direction, and the right end portion of the side bar 16A (see FIG. 1) is a bolt 48 and a collar. 50 and a nut 52 are slidably supported. That is, the right end portion of the side bar 16A is configured as a non-fixed end (thermal expansion / contraction absorbing portion). The bolt 48 is inserted into the through hole 54 at the right end of the side bar 16 </ b> A and the collar 50 and fastened to the nut 52. The collar 50 is slidably supported along the long hole 56 of the bracket 46.

  As shown in the plan view of the bracket 46 shown in FIG. 4B, the long hole 56 is opened along the longitudinal direction of the bracket 46, that is, the longitudinal direction of the side bar 16A. The collar 50 is slidably supported within the range of the length in the longitudinal direction of the long hole 56, and the thermal expansion / contraction difference between the frame structure 12 and the support bars 14A to 14D, and the support bars 14A to 14D. And the thermal expansion / contraction difference between the side bars 16A to 16H can be absorbed.

<Pin 18>
As shown in FIG. 1, the pins 18 are arranged in alignment along the longitudinal direction of the side bars 16 </ b> A to 16 </ b> H and project in the horizontal direction. A vertical edge portion of the glass plate G housed in the frame structure 12 is supported by the pin 18. The pin 18 may be fixed to the side bars 16 </ b> A to 16 </ b> H by welding or a fitting structure using holes or grooves.

  Moreover, the length of the pin 18 which contacts the vertical edge part of the glass plate G is the length (for example, 10 mm) or less corresponding to the removal area | region where the peripheral part of the glass plate G is removed in a post process of a chemical strengthening process. It is preferable to set to. Thereby, since the pin 18 does not contact the product region except the removal region, the product region is chemically strengthened without being affected by the contact of the pin 18.

  FIG. 5 is a main part explanatory view showing a form in which the glass plate G1 is stored in the glass plate storage body 10 in the vertical direction. FIG. 6 is a main part explanatory view showing a form in which the glass plate G2 is stored in the glass plate storage body 10 at a predetermined angle with respect to the vertical direction.

  As shown in FIG. 5, the glass plate G <b> 1 is accommodated in the vertical direction by supporting the vertical edge portions of a plurality (four in FIG. 5) of pins 18 arranged in the vertical direction.

  On the other hand, the glass plate G2 shown in FIG. 6 is a glass plate that is thinner than the glass plate G1 of FIG. 5 and is easily bent by its own weight. When the glass plate G2 is stored in the vertical direction, the glass plate G2 is bent by its own weight, and the bending direction does not follow the same direction, so that adjacent glass plates G2 may come into contact with each other.

  In order to prevent such contact, as shown in FIG. 6, the glass plate G2 is stored while being inclined in the same direction. Thereby, since all the glass plates G2 of FIG. 6 bend in the same direction, it is possible to prevent the adjacent glass plates G2 from contacting each other. Since the thickness of the glass plate for FPD is as thin as 0.2 to 0.7 mm, in the case of such a glass plate, it is preferable to store the glass plate with an inclination as shown in FIG.

  When the glass plate G2 is tilted and stored, the horizontal positions of the side bars 16A to 16D (also the side bars 16E to 16H) are changed from the positions in FIG. It is preferable to change the position of the pin 18 to a position where it can be supported. For the horizontal positioning of the side bars 16A to 16D, the marks m1, m2, m3, and m4 previously attached to the side bars 16A to 16D are aligned with the marks M1, M2, M3, and M4 previously attached to the support bar 14A. Can be done. Further, the horizontal positioning is performed using the long hole 44 shown in FIG. 3B and the long hole 56 shown in FIG. 4B. In addition, the horizontal positioning method of the side bars 16A to 16D may be other than the method using the mark.

  FIG. 7 is a perspective view showing a storage form of the glass plate G2 shown in FIG. When the vertical edge portions on both sides of the glass plate G2 are supported by the pins 18, the central portion of the glass plate G2 is bent by its own weight, but the bending direction follows the direction along the inclined direction. Contact between the plates G2 is prevented. In addition, the broken line of FIG. 7 has shown the thick glass plate G1 shown in FIG.

[Characteristics of glass plate housing 10]
<First feature>
The first feature is that a plurality of glass plates of different sizes can be stored using one glass plate storage body 10.

  1 first adjusts the horizontal position of the support bars 14A to 14D according to the size (width dimension: vertical dimension or horizontal dimension) of the glass sheet G, and then supports the support bar. 14A to 14D are fixed to the frame structure 12 using bolts or the like. Next, the side bars 16A to 16H are attached to the support bars 14A to 14D. In this case, one end is a fixed end and the other end is an unfixed end. When the glass plate G is housed in the frame structure 12, the vertical edge portions on both sides of the glass plate G are brought into contact with and supported by the plurality of pins 18. Thereby, the several glass plate G can be accommodated with respect to the frame structure 12 in the direction (refer FIG. 6) inclined with respect to the perpendicular direction (refer FIG. 5) or a perpendicular direction.

  8, 9, and 10 are front views of the glass plate storage body 10 that stores a plurality of types of glass plates G3, G4, and G5 having different sizes.

  In the glass plate storage body 10 of FIG. 8, in order to store the small size glass plate G3 in the center of the glass plate storage body 10, the interval between the support bars 14A and 14D (the same applies to the support bars 14B and 14C) is reduced. The support bars 14A and 14D are fixed to the upper beam 22A and the lower beam 24A using bolts 32 and 34, respectively. Further, unnecessary side bars 16C, 16D, 16G, and 16H in the vertical direction are removed from the support bars 14A and 14D, and the glass plate G3 is supported by the pins 18 of the four side bars 16A, 16B, 16E, and 16F. .

  In the glass plate storage body 10 of FIG. 9, one support bar 14D is added to the glass plate storage body 10 of FIG. 8 in order to store two types of glass plates G3 and G4 having different sizes. The additional support bar 14D is positioned at a position in the horizontal direction according to the size of the glass plates G3 and G4 using the long holes 28B and 30B. Further, the existing support bars 14A and 14D are also positioned at positions corresponding to the sizes of the glass plates G3 and G4.

  Also in the glass plate storage body 10 of FIG. 9, unnecessary side bars 16C, 16D, and 16H in the vertical direction are removed from the support bar 14A and the two support bars 14D. The glass plate G3 is supported by the pins 18 of the four side bars 16A, 16B, 16E, and 16F, and the glass plate G4 is supported by the pins 18 of the six side bars 16E, 16F, and 16G.

  In the glass plate container 10 of FIG. 10, one support bar 14A and 14D is added to the glass plate container 10 of FIG. 8 in order to store two types of glass plates G3 and G5 of different sizes. ing. The additional support bars 14A and 14D are positioned at positions corresponding to the sizes of the glass plates G3 and G5 using the long holes 28B and 30B. Further, the existing support bars 14A and 14D are also positioned at positions corresponding to the sizes of the glass plates G3 and G5.

  In the glass plate container 10 of FIG. 10, the glass plate G3 is supported by pins 18 of four side bars 16A, 16B, 16E, and 16F, and the glass plate G5 has six side bars 16A, 16B, 16C, It is supported by pins 18 of 16E, 16F, and 16G.

  As described above, according to the glass plate container 10 of the embodiment, a plurality of types of glass plates having different sizes can be used by using common members (support bars, side bars, pins) without using other members. G, G3, G4, and G5 can be accommodated. Therefore, it is possible to provide a versatile glass plate storage body 10 that can handle a plurality of types of glass plates having different sizes.

  Moreover, since the glass plate storage body 10 can be reduced in weight by removing the unnecessary side bar which does not contribute to storage of a glass plate, handling of the glass plate storage body 10 in the chemical strengthening process of a glass plate becomes easy.

<Second feature>
The second feature is that the glass plate housing 10 is provided with a thermal expansion / contraction absorbing portion that absorbs the thermal expansion / contraction difference. In the embodiment, the thermal expansion / contraction absorbing portion is achieved at the non-fixed end of the side bar 16A shown in FIG.

  When the glass plate container 10 is used for the chemical strengthening treatment, it is affected by heat from the molten salt at a high temperature (for example, 350 to 500 ° C.), and when immersed in the molten salt, each member is thermally expanded. When taken out from the molten salt, each member shrinks thermally.

  That is, a thermal expansion / contraction difference occurs between the frame structure 12 and the support bars 14A to 14D, or a thermal expansion / contraction difference occurs between the support bars 14A to 14D and the side bars 16A to 16H. In this case, as shown in FIG. 4B, the collar 50 slides in the range of the length of the long hole 56 in the longitudinal direction, so that the thermal expansion / contraction difference can be absorbed. Thereby, generation | occurrence | production of malfunctions, such as a failure | damage by the thermal stress of the frame structure 12 and support bar 14A-14D, curvature, and a distortion, can be prevented.

  Further, since the thermal expansion / contraction absorbing portion is constituted by the non-fixed end, the glass plate housing 10 can be provided with the thermal expansion / contraction absorbing portion without reducing the rigidity of the frame structure 12. Furthermore, even when the frame structure 12 is plastically deformed by thermal stress, the deformation can be absorbed by the thermal expansion / contraction absorbing portion. Furthermore, even when the plastic deformation occurs, the horizontal positions of the side bars 16A to 16D with respect to the support bars 14A to 14D can be adjusted by the long holes 44 and 56 so as to cancel the plastic deformation amount. Thereby, even if it is the glass plate storage body 10 which deformed plastically, the glass plate storage body 10 can be reproduced in the initial form.

<Third feature>
A third feature is that the horizontal position of the pin 18 can be adjusted by adjusting the horizontal position of the side bars 16A to 16H with respect to the support bars 14A to 14D.

  Thereby, as shown in FIG. 5, FIG. 6, the accommodation attitude | position of the glass plates G1 and G2 by which the vertical edge part is supported by the pin 18 can be changed. That is, the storage posture of the glass plates G1 and G2 can be changed to the vertical direction and the direction inclined with respect to the vertical direction. As shown in FIG. 6, when a plurality of glass plates G2 are tilted and stored at the same inclination angle, the warp direction due to the weight of the glass plate G2 is equal to the amount of warpage, so that the adjacent glass plates G2 and G2 are adjacent to each other. Can be prevented.
