The guide piece 12b is formed with two slit holes 12c penetrating at predetermined intervals in the direction perpendicular to the length direction, and the holding piece 12d is provided with two gripping portions 22 on both end sides.

  A shaft in which a metal rod-like shaft 13 is rotatable and floats along the length direction of the sandwiching portion 12 is inserted in a gap formed between the contact piece 12a and the guide piece 12b. Two circumferential grooves 13a are formed in the shaft 13 at the same interval as the two slit holes 12c, and the surface of the shaft 13 is coated with a rubber-like elastic buffer material 13b.

  An operating member 15 is attached to the shaft 13 via a guide piece 12b. The operating member 15 has two C-shaped circles formed so as to be partially cut out with a hard plastic material. The ring body 17 is connected to the rectangular rod-shaped operation body 16 via the connecting plate 17a, and the two C-shaped ring bodies 17 are spaced at the same intervals as the pair of slit holes 12c and the circumferential groove 13a.

  Then, as shown in FIG. 5C, the shaft 13 moves in the vertical direction by its own weight by being inserted to a position where the upper end side G <b> 1 of the glass substrate G protrudes above the central portion of the shaft 13. Thus, the glass substrate G is fitted in the gap between the glass substrate G and the guide piece 12b, and the both side surfaces of the glass substrate G are securely held by the wedge action via the shaft 13. Since the C-shaped torus 17 of the operating member 15 is loosely fitted in the circumferential groove 13a, there is no hindrance to the rotation of the shaft 13 and the vertical movement due to its own weight.

  In addition, since the surface of the shaft 13 is coated with the buffer elastic material 13b, the glass substrate G can be firmly fixed by increasing the frictional force between the glass substrate G and the shaft 13 and thereby fixing the position of the glass substrate G. Even during transfer of G, it does not fall off from the clamping part 12. Further, the contact surface between the glass substrate G and the shaft 13 is protected by the elasticity of the buffer elastic material 13b.

As described above, the operating body 16 can be moved from the outside of the clamping unit 12 and can be pushed upward while allowing the shaft 13 to rotate, so that the glass substrate G can be easily and smoothly removed.

  Next, the restriction part 19 of the gripping tool 11 will be specifically described. As shown in FIG. 7A, the fixing member 20 provided on the outer surface side of the abutting piece 12a of the holding portion 12 is formed with a sliding groove 20b penetrating in the vertical direction, and slides from the outside. A female screw hole 20a is formed toward the groove 20b. The restricting portion 19 is composed of a plate-shaped metal plate, and has a L-shaped cross section including a vertical plate 19a parallel to the glass substrate G surface and a horizontal plate 19b orthogonal to the vertical plate 19a on the lower end side G3 side of the glass substrate G. Is formed. A regulating piece 19c extends upward from the end of the horizontal plate 19b.

  In order to attach the restricting portion 19 to the sandwiching portion 12, first, the vertical plate 19a is inserted into the sliding groove 20b of the fixing member 20 in the direction indicated by the arrow, and as shown in FIG. The horizontal plate 19b is inserted into a position close to the lower end side G3, and the male screw 21a provided on the adjustment handle 21 is screwed into the female screw hole 20a of the fixing member 20, so that the vertical plate 19a is engaged with the contact piece 12a.

That is, by rotating the adjustment handle 21, the effective length of the vertical plate can be adjusted in accordance with the size of the vertical width of the glass substrate, and the horizontal plate 19b can be brought close to the lower end side G3 of the glass substrate G. .

  As described above, even when deformation occurs during the transfer of the glass substrate G by the restricting portion 19 including the L-shaped vertical plate 19a and the horizontal plate 19b, the deflection of the central portion of the glass substrate G is vertical. It is suppressed by the plate 19a, and the swing of the lower end side G3 of the glass substrate G is suppressed by the horizontal plate 19b. In addition, the swing width is regulated in advance so that the lower end side G3 of the glass substrate G is not greatly shaken by the regulation piece 19c provided in the horizontal portion 19b.

  From the above description, since the glass substrate G is stably gripped by the gripping tool 11, the glass substrate G can be easily placed in the box body 4 using the handle 22 of the gripping tool 11 as shown in FIG. 8. The both ends of the holding tool 12 are placed in the support groove 7 to support the entire holding tool 11, the lower end side G3 is inserted into the groove of the bottom surface pad 6 of the glass substrate G, and the side end side G2, G2 ′ is inserted into the grooves of the side pads 5 and 5 ′, and the upper end pad 2b of the lid body 2 presses the upper end of the sandwiching portion 12, so that the glass substrate G in the transport box 1 during transport Stable against shaking.

Then, since the glass substrate G can be suspended by the gripper 11, the glass substrate G can be quickly and easily transferred without directly touching the glass substrate G. This transfer causes deformation of the glass substrate G. However, since the deflection and the shaking of the glass substrate G are always restricted by the restricting portion 19, the glass substrate G can be prevented from being damaged at the time of transfer, and the glass substrate G can be transferred safely. Moreover, when removing the glass substrate G from the clamping part 12, the glass substrate G can be simply removed by operation of the operation member 15 mentioned above.

  When the glass substrate G is large or heavy, it is difficult to transfer the glass substrate G by a normal manual operation. Therefore, as shown in FIG. A holding hole 12e is formed in the holding piece 12d, and a large or heavy glass substrate G can be transferred by hooking the wire 30a from the crane 30 to the holding hole 12e and performing a lifting operation. Further, the work can be smoothly performed during the storage and removal from the transport box 4 ′. Further, two metal annular rings are connected and provided between the left and right wires 30a, and when the glass substrate G is lifted and lowered by the crane vehicle 30 by these annular rings, the shaking of the glass substrate G is stopped as much as possible. It is supposed to let you.
