Glass plate packing body

Abstract

In the case of packing a glass plate stacked body while holding it on a pallet by means of a plurality of retaining bars arranged in parallel across the glass plate stacked body in the width direction, the pressing force acting on the glass plate stacked body by the retaining bars is rationalized, thus restraining collapse of cargo of the glass plate stacked body. A plurality of glass plates are stacked in vertical posture on a pallet (2) having a pedestal portion (2a) and a backrest portion (2b), two retaining bars (4, 5) are arranged in parallel at an interval in the vertical direction across the glass plate stacked body G in the width direction, and the glass plate stacked body G is held on the pallet (2) by fastening the opposite ends of the retaining bars (4, 5) to the side of the backrest portion (2b) by means of fastening members (7, 8). In the glass plate stacked body packing body (1), a pressing force acting on the glass plate stacked body G by the lower retaining bar (5) is set stronger than a pressing force acting on the glass plate stacked body G by the upper retaining bar (4).

Description

technical field [0001] This invention relates to the improvement technique of the glass plate package which hold|maintains the glass plate laminated body which laminated|stacked the some glass plate on the tray. Background technique [0002] As is well known, when transporting various glass plates such as glass substrates for flat panel displays such as liquid crystal displays and plasma displays, they are usually transported in a glass plate package in which a plurality of glass plates are laminated. The stack is held on the tray. [0003] Such a glass plate package is roughly divided into a glass plate package that holds a plurality of glass plates stacked in a vertical orientation on a tray, and a glass plate package that holds a plurality of glass plates stacked in a horizontal orientation on a tray. . [0004] As the former package, for example, there is a package that is stacked in a vertical orientation on a tray having a base portion supporting the lower side porti...

AI Technical Summary

Problems solved by technology

Therefore, when the same pressing force is applied to the upper part and the lower part of the glass plate laminate by different pressing rods, the laminated thickness of the upper part becomes thinner than that of the lower part, and the laminated state tends to become uneven.

Such a tendency becomes more noticeable during the conveyance of the package, and becomes the cause of the collapse of the glass plate laminate.

[0008] In addition, when the glass plate laminate collapses, when the package is opened to take out the glass plate, troublesome and complicated operations may be forced.

In addition, in the state where the glass plate laminate has collapsed, since the upper part of the glass plate laminate whose lamination thickness is relatively thinner is kept in a compressed state than the lower part, therefore, during transportation, when the package body When an impact such as being pushed from the bottom up occurs, there is no room for the upper part of the glass plate to move, and the impact directly acts on the lower edge of the glass plate, which may cause damage to the glass plate

[0009] On the other hand, in a glass sheet laminate in which a plurality of glass sheets are laminated in a horizontal orientation, when the same pressing force is applied to the front and rear portions of the glass sheet laminate by different pressing rods, the glass sheet during conveyance The laminated body is displaced laterally from the reference part of the pallet in the direction away from it, and the glass plate laminated body is prone to collapse

In addition, when the glass plate laminate collapses, troublesome and cumbersome operations are forced to be performed when the package is opened to take out the glass plate. Depending on the situation, the glass plate separated from the reference part during transportation may again come into contact with the reference part and may be damaged.

[0010] The above-mentioned problems may be caused by inappropriate pressing force applied to the glass plate laminate by the pressing bar, and it is desirable to optimize the pressing force generated by the pressing bar.
