TECHNICAL FIELD The present invention relates to a glass plate laminate, a pallet and a glass plate package, and more particularly, to a glass plate laminate, a pallet and a glass plate package in which a plurality of glass plates are laminated via sheets such as paper.

As glass plates, glass substrates for flat panel displays (FPDs), such as glass plates for construction, glass plates for automobiles, and glass substrates for plasma displays and glass substrates for liquid crystals, are scratched or contaminated on the surface during storage or conveyance, resulting in product defects. easy. In particular, when used as a glass substrate incorporating an electric circuit in its use surface, such as an alkali-free glass substrate used for a glass substrate for liquid crystal display, even if there is slight scratches or contamination on the use surface thereof, disconnection and patterning defects occur. Occurs. Therefore, very high surface properties are required for such glass substrates.

Therefore, the glass plate laminated body which interposed the so-called laminated paper which interposes the surfaces of adjacent glass plates through the paper between the glass plates to be laminated | stacked and the glass plate as a method of preventing the wound and contamination during storage or conveyance of a glass plate is patent document 1 Is disclosed in.

In the glass plate laminated body of patent document 1, a plurality of glass plates and paper are laminated | stacked alternately on the vertical lamination pallet which leans and stacks a glass plate at an angle.

In addition, Patent Document 2 discloses a horizontal laminated glass plate laminate in which a protective sheet is interposed between a plurality of glass plates, and laminated on a pallet in a horizontally arranged state.

By the way, in the manufacturing process, the stripe according to the shaping direction (drawing direction of a glass ribbon) of a glass plate is formed in the surface of the glass plate laminated | stacked on a pallet.

Striping is stripe which arises in the extending | stretching direction of a glass plate due to the fluctuation | variation of plate | board thickness and curvature in the direction perpendicular | vertical to the extending | stretching direction of a glass plate (glass ribbon). The direction in which the stripes extend is called the stripe direction.

Moreover, the fault of the bubble (including opening bubble) which exists in a glass ribbon is a spherical shape, catches it in this stripe direction on the basis of the viscous history of the glass after the time a bubble was generated, and the history of the tensile force in the extending direction. It becomes an extended form. Moreover, this stripe is formed in a glass plate also by the float method and the fusion method which are the manufacturing methods of a glass plate.

As shown in FIG. 7, the rectangular platelets whose direction of the long side is the same as the stretching direction of the glass ribbon GR are taken as the platelets G ₁ of the long side stripes, and the direction of the short side of the glass ribbon GR is shown. A rectangular platelet that is the same as the stretching direction may be plated as a platelet G ₂ of short side stripes. However, FIG. 7 is an illustration of the method of collecting, and the printing may be performed by another method. For example, if the chaepan the platelets (G ₁₎ of the long side stripes from the glass ribbon (GR), when vertically divided into the platelets (G ₁₎ to the long side, obtained the platelets (G ₂₎ of the short side stripes There is. In this manner, the platelets thus plated may be divided to cut out platelets of desired stripes.

In addition, as the glass ribbon GR used by a plate | plate, you may use the glass ribbon produced | generated by the float method, for example, but the glass ribbon produced | generated by methods other than the float method (for example, a longitudinal pull manufacturing method etc.) You may use it.

As shown in FIG. 4, the glass plate G of the long side stripe shown in FIG.6 (a) or the glass plate G of the short side stripe shown in FIG.6 (b) is a glass plate laminated body of embodiment ( As 12), in the state in which the direction of the stripe 52 formed in the surface of the glass plate G was unified, the glass plate G of several sheets (three pieces in FIG. 4) is accommodated in the pallet 14 of FIG. It is.

Thus, in the glass plate laminated body 12 of embodiment, in the state which unified the direction of the stripe 52 which arose in the surface of glass plate G at the time of manufacture of glass plate G, the glass plate G of the total number of sheets is carried out. It is stored in the pallet 14. Thereby, the problem, such as the fall of product yield at the time of manufacture of the product using the said glass plate resulting from the laminated glass plate laminated body which does not unify the direction of the streak 52, can be eliminated.
