Embodiment Construction

[0040] Hereinafter, modes for implementing the present invention will be described with reference to the drawings.

[0041] Structure of the glass plate storage body of Embodiment 1

[0042] figure 2 It is a perspective view which shows Embodiment 1 of the glass plate storage body of this invention. Such as figure 2 As shown, the glass plate storage body 100 is configured to accommodate a plurality of glass plates 110 in a vertical state ( figure 2 , indicated by a single dotted line) is used, for example, in the process of lowering the glass plate 110 into the molten salt tank by an elevating device (not shown) into the molten salt and performing chemical strengthening treatment.

[0043] The glass plate storage body 100 is formed by combining a plurality of pillars 102 and a plurality of beams 104 and 106 in a rectangular parallelepiped shape, and has a structure having a plurality of openings in each direction in order to facilitate the inflow and outflow of molten ...

Abstract

The present invention is a glass plate housing body that is put into a molten salt when chemically strengthening a plurality of glass plates and is provided with: a housing part that houses the plurality of glass plates in a vertical state; a mounting part provided in the bottom of the housing part and in which lower edges of the plurality of glass plates are mounted; and a plurality of support parts that protrude to the inside of the housing part so as to support both sides of the plurality of glass plates. The plurality of support parts have expanded parts that contact peripheral edge parts of the glass plates and constricted parts on the base end parts of the expanded parts. The expanded parts are expanded in a direction orthogonal to the axis of the support parts.

Description

technical field [0001] The present invention relates to a glass plate storage body and a method for manufacturing chemically strengthened glass. Background technique [0002] As one method of strengthening a glass plate, there is, for example, a method in which a glass plate is dropped into molten salt such as potassium nitrate and chemically strengthened (for example, refer to Patent Document 1). In this method, a glass plate storage body containing a plurality of glass plates is put into a molten salt tank heated to 400°C to 450°C, immersed for a predetermined time to perform ion exchange, and compressive stress is formed on the surface of the glass plate. layer. [0003] In order to improve the processing efficiency of one input operation, it is desired to increase the area of ​​the glass plate, and it is desired to increase the number of glass plates accommodated in the glass plate storage body. In addition, for example, when a glass plate is used as a cover for a port...
