On the upper surface of the bottom surface pad 44, ribs 42 that form parallel grooves having a mountain-shaped cross section, for example, 14 mm pitch intervals are formed.

  In addition, on the inner surfaces of the opposing side plates 8a and 8b on the short side of the box main body 2, for example, 40 vertical grooves are formed on the upper surface of the base member 48a that is separated vertically and spaced apart by a predetermined distance. Thus, the side surface pad 48 in which the plurality of guide rib members 48b are configured is attached via an adhesive or the like.

  The bottom surface pad 44 and the side surface pad 48 are set so that the vertical grooves formed by the guide rib members 48b of both the base members 48a and the parallel grooves of the bottom surface pad 44 are accurately aligned when being attached.

  Therefore, as shown in FIGS. 4A and 4B, the lower ends of the plurality of glass substrates G are supported on the bottoms of the parallel grooves of the bottom surface pad 44, but both side ends of the glass substrates G touch the base member 48a. A slight gap S is formed without any problem.

  These longitudinal grooves formed by the guide rib member 48b support the glass substrate G in parallel, and guide the glass substrate G to be accommodated in or removed from the parallel grooves formed between the ribs 42 of the bottom surface pad 44. Function as.

  The guide rib member 48b has a tapered surface tapered from the top surface to the groove bottom so that the cross-sectional shape thereof is substantially C-shaped, and the guide rib member 48b is also near the opening of the box body 2. A mountain-shaped taper surface is formed so that the height on the side gradually decreases toward the opening end.

  Next, the base member 48a and the guide rib member 48b of the side pad 48 of the glass substrate carrying box configured as described above will be described in further detail.

  First, as shown in FIG. 3, with the lid 3 of the glass substrate transport box 1 opened, the side edges of the glass substrate G supported in a vertical state by a special fork (not shown) sequentially from the side plate 6a side. From the upper side, it is inserted into a vertical groove formed between the pair of guide rib members 48b and the lower end thereof is supported by the groove bottom of the corresponding parallel groove of the bottom surface pad 44. In this state, as shown in FIG. As described above, both side edges of the glass substrate G are held in a state where a slight gap S is formed with respect to the base member 48a.

  When the glass substrate G is inserted, the guide rib member 48b having a substantially C-shaped cross section is guided from the top surface to the groove bottom by a tapered surface and a mountain-shaped opening end, so that the glass substrate at the time of insertion There is room for accurate positioning of G. Further, since the thickness of the base member 48a gradually decreases toward the opening end, the base member 48a is centered with respect to the deviation in the width direction of the glass substrate G when inserted near the opening end.

  In this manner, the box main body 2 with both side edges of the glass substrate G inserted into the vertical grooves between the guide rib members 48 b and the lower ends thereof supported by the groove bottoms of the corresponding parallel grooves of the bottom surface pad 44. When the opening is closed by the lid 3, the upper and lower ends of the plurality of glass substrates G accommodated in the transport box 1 are on the back of the lid 3, as shown in FIGS. 5 (a) to 5 (c). Are pressed simultaneously from the X direction between the pressing surface 58 a of the glass substrate contact pad 58 and the bottom surface pad 44.

  When a load in the X direction is applied toward the upper and lower ends of the glass substrate G, as shown in FIGS. 5A and 5B, the guide rib members 48b separated vertically are orthogonal to the plane of the glass substrate G. A forced deflection that curves in either the left or right direction (Z-axis) is formed.

  That is, as shown in FIG. 5C, when the vertical loads X1, X′1 and X2, X′2 are simultaneously applied to the upper and lower ends of the glass substrate G, the longitudinal direction (X The maximum deflection amount Z1 in the Z-axis direction is formed at the intermediate portion in the axial direction.

  In this state, when a load is applied from the horizontal axis (Y-axis) direction orthogonal to the vertical axis X-axis of the glass substrate G to the left and right ends, the deflection other than the direction in which the deflection occurs is suppressed, and FIG. As shown in (c), the deformation formed in the Z-axis direction is unlikely to cause deformation in the intermediate portion in the horizontal axis (Y-axis) direction, and the central portion of the glass substrate G is greatly bent and deformed to hit the adjacent glass substrate G. Things that come in contact do not happen.

  Further, since the side pads 48 are arranged separately from each other on the inner surfaces of the pair of opposing side plates 8a and 8b of the box body 2 except for the intermediate portion, the material cost of the side pads 48 is increased. It is also possible to replace only the upper base member 48a which is reduced and easily damaged when the glass substrate G is inserted.

  Further, a bottom surface pad 44 is provided on the bottom surface of the box body 2, and a plurality of parallel grooves for supporting the glass substrate G are formed on the bottom surface pad 44 so as to align with the vertical grooves formed between the pair of guide rib members 48 b. Therefore, the lower edge of the glass substrate G can be stably supported with a predetermined interval.

  A glass substrate abutment pad 58 that presses and holds the upper edges of the plurality of glass substrates G is formed on the lid 3 by a conductive flexible material to electrically connect the lid 3 side of the glass substrate G and the box body 2. Therefore, the glass substrate G can be prevented from being damaged and charged at the same time.

  And since the box main body 2 and the cover body 3 are comprised with the resin foam, while being able to comprise a conveyance box lightweight, the impact of the force which acts from the outside can be relieved.

  The box body 2 is provided with bottom frames 10 and 12 made of hard aluminum on the outer peripheral edges of the four sides of the bottom plate 4 and upper frames 22 and 24 on the outer peripheral edges of the upper side. Since the square pad-shaped reinforcing corner plate 18 is attached to the corner where the two frames intersect, and the bottom frames 10 and 12 and the upper frames 22 and 24 are connected by the frame pillar 20, the robust transport box 1 can be provided. There is no risk of deformation due to contact with other articles or long-term storage.
