Description
本発明は、ガラス積層体の製造方法の技術に関する。 The present invention relates to a technology of a method for manufacturing a glass laminate.
従来、耐貫通性および耐衝撃性などに優れたガラス製品として、ガラス積層体が知られている。
ガラス積層体は、一般的に、積層工程、袋収容工程、および圧着工程などからなるＡＣＶ法（オートクレーブ法）によって製造される。
具体的には、樹脂製中間膜を介在させつつ少なくとも二枚の板ガラスを積層し（積層工程）、積層された板ガラスを脱気用の袋部材に収容し（袋収容工程）、板ガラスを収容した袋部材を真空引きするとともにオートクレーブによって加熱・加圧処理することで（圧着工程）、ガラス積層体は製造される。
BACKGROUND ART Conventionally, a glass laminate has been known as a glass product having excellent penetration resistance and impact resistance.
The glass laminate is generally manufactured by an ACV method (autoclave method) including a lamination step, a bag accommodation step, a pressure bonding step, and the like.
Specifically, at least two sheet glasses are laminated with a resin interlayer interposed therebetween (lamination step), the laminated sheet glass is accommodated in a bag member for deaeration (bag accommodation step), and the sheet glass is accommodated. The glass laminate is manufactured by evacuating the bag member and performing heat and pressure treatment by an autoclave (pressure bonding step).
ところで、前述した圧着工程において、例えば、板ガラスと樹脂製中間膜との間に気泡などが残り欠陥商品となるのを防止したり、あるいは、板ガラスと樹脂製中間膜との密着性を高めることを目的として、オートクレーブの炉内の加圧と同時に、当該オートクレーブの炉内に投入された板ガラスを収容した袋部材を、真空引きしている。
そして、このようなガラス積層体を製造する際の技術として、例えば、合わせガラスの製造方法および製造装置に関する技術が「特許文献１」によって開示されている。
具体的には、「特許文献１」においては、二枚以上の板ガラスの間に樹脂製中間膜を介在させたガラス積層体を、真空状態にすることが可能な領域内に配設し、その後、当該領域内を真空状態にするとともに、前記ガラス積層体に対して、前記樹脂製中間膜が軟化するように加熱しつつ、板ガラス間の間隙を狭める方向に圧縮することによって脱気を行い、板ガラス間を接着する合わせガラスの製造方法および製造装置が開示されている。
By the way, in the above-mentioned pressure bonding step, for example, to prevent bubbles and the like from remaining as defective products between the sheet glass and the resin interlayer, or to improve the adhesion between the sheet glass and the resin interlayer. For the purpose, simultaneously with the pressurization in the furnace of the autoclave, the bag member containing the plate glass put into the furnace of the autoclave is evacuated.
As a technique for manufacturing such a glass laminate, for example, a technique relating to a manufacturing method and a manufacturing apparatus of a laminated glass is disclosed in “Patent Document 1”.
Specifically, in “Patent Document 1”, a glass laminate in which a resin interlayer is interposed between two or more sheet glasses is disposed in a region where a vacuum state can be obtained, and thereafter, While the inside of the region is in a vacuum state, the glass laminate is degassed by heating in such a way that the resin interlayer is softened and compressed in a direction to narrow the gap between the glass sheets, A manufacturing method and a manufacturing apparatus of a laminated glass for bonding sheet glass are disclosed.
しかしながら、例えば、図４に示すように、前述した圧着工程において、オートクレーブによって加熱・加圧処理する際に、板ガラス１間に介在させた樹脂製中間膜２が加熱によって軟化するため、板ガラス１が互いにずれたガラス積層体３となることがあった。
その結果、ガラス積層体は、各板ガラスが水平且つ任意の方向にずれ、平面視における縦・横の寸法が均一とならないため、縦・横の寸法を同一寸法とするようにトリミング加工を施すことが必要となり、工程数が増加し、ガラス積層体のコスト低減を図ることが困難であった。
However, for example, as shown in FIG. 4, in the above-described pressure bonding step, when heating and pressure treatment is performed by an autoclave, the resin intermediate film 2 interposed between the sheet glasses 1 is softened by heating, so that the sheet glass 1 In some cases, the glass laminates 3 were shifted from each other.
As a result, the glass laminate is subjected to a trimming process to make the vertical and horizontal dimensions the same because the respective glass sheets are displaced horizontally and in any direction and the vertical and horizontal dimensions are not uniform in plan view. Was required, the number of steps was increased, and it was difficult to reduce the cost of the glass laminate.
本発明は、以上に示した現状の問題点を鑑みてなされたものであり、少なくとも二枚の板ガラスの間に樹脂製中間膜を介在させて積層したガラス積層体に対して、オートクレーブによる加熱・加圧処理を行うと同時に真空引き処理を行う場合において、板ガラス同士の位置ずれが生じることを抑えることができるガラス積層体の製造方法を提供することを課題とする。 The present invention has been made in view of the current problems described above, and a glass laminate laminated by interposing a resin interlayer between at least two sheet glasses is heated by an autoclave. It is an object of the present invention to provide a method for manufacturing a glass laminate that can suppress the occurrence of displacement between sheet glasses when performing a vacuuming process simultaneously with a pressing process.
本発明の解決しようとする課題は以上の如くであり、次にこの課題を解決するための手段を説明する。 The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

At the same time, a method of manufacturing a glass laminate is performed in which the glass sheets are pressed against each other to produce a glass laminate by performing a vacuum evacuation process on the bag member, wherein a contact member is applied to two adjacent side surfaces. The glass laminate is housed in the bag member in a state of being in contact therewith.
このような構成からなるガラス積層体の製造方法によれば、ガラス積層体の側面部に当て部材を当接することにより、加熱・加圧処理時において、樹脂製中間膜が軟化した場合であっても、板ガラス同士の位置ずれが生じることを抑えることができる。
従って、寸法が均一なガラス積層体を製造することができる。
その結果、トリミング加工を施すことなく寸法が均一なガラス積層体を製造することが可能となり、工程数が増加することもなく、ガラス積層体のコスト低減を図ることができる。
According to the method for manufacturing a glass laminate having such a configuration, the contact member is brought into contact with the side surface portion of the glass laminate, and during the heating and pressurizing treatment, the resin interlayer is softened. In addition, it is possible to suppress the occurrence of displacement between the sheet glasses.
Therefore, a glass laminate having uniform dimensions can be manufactured.
As a result, it is possible to manufacture a glass laminate having uniform dimensions without performing trimming, and it is possible to reduce the cost of the glass laminate without increasing the number of steps.
また、本発明に係るガラス積層体の製造方法において、前記当て部材は、前記ガラス積層体の側面部に当接する当接面の面積が前記ガラス積層体の側面部の面積よりも小さいことがより好ましい。 In the method for manufacturing a glass laminate according to the present invention, the contact member may be configured such that an area of an abutting surface that abuts on a side surface of the glass laminate is smaller than an area of a side surface of the glass laminate. preferable.
このような構成からなるガラス積層体の製造方法によれば、ガラス積層体の側面部に当て部材を当接した状態で袋部材に入れ易くなり、作業性を向上させることができる。 According to the method of manufacturing a glass laminate having such a configuration, the glass laminate can be easily put into the bag member in a state where the contact member is in contact with the side surface portion, and workability can be improved.
