As seen in Publication No. 129413, a laminated glass assembly is made by sandwiching a thermoplastic resin adhesive layer between multiple transparent plates, and the laminated glass assembly is moved to a preheating chamber, and the assembly is sealed by its own weight. After preheating the assembly to a temperature that does not exceed the temperature range, the assembly is transferred to a vacuum/heating tank, the vacuum/heating tank is depressurized to evacuate the interior of the laminated glass assembly, and the assembly is heat-sealed with an adhesive layer. A method is known in which the laminated glass assembly is heated to a temperature higher than the temperature, then the atmosphere is introduced into the tank, and the pressure is set to the atmospheric pressure or higher to bond the laminated glass assembly. Furthermore, in Japanese Patent Application Laid-Open No. 50-27812, a laminated glass assembly is made by sandwiching an adhesive layer of thermoplastic resin such as polyvinyl butyral between two glass plates, and the adhesive surface is placed around the assembly. attaching a heat-resistant rubber ring having a vent opening in the heat-resistant rubber ring, then depressurizing the adhesive layer portion of the laminated glass assembly through the vent hole in the heat-resistant rubber ring to degas the adhesive layer portion; A method is described in which laminated glass is produced by heating to 90° to 110°C for temporary adhesion, followed by autoclave treatment.

があつた。 These conventional methods create an assembly and then depressurize the adhesive layer of the assembly, so even if the adhesive layer is embossed,
There was a drawback that the embossing was easily crushed and the gap between the glass plate and the adhesive layer was eliminated, making it impossible to perform air defoaming sufficiently. In particular, when a sticky thermoplastic resin adhesive that is plastic at room temperature is used for the adhesive layer, defoaming becomes more difficult, and this tendency becomes more severe as the adhesive layer becomes thinner. It was hot.

In a method of manufacturing a laminate by pressing, one transparent plate having the adhesive layer attached thereto or the other transparent plate is placed against an inclined conveyor, and the lower end of the other transparent plate is placed against the inclined conveyor. By aligning the lower ends of the hanging transparent plates and locking the upper ends to support pins that can be operated from outside the container to be depressurized, the transparent plates are stacked one on top of the other with a space between them and the adhesive layer facing inside. Place it on an inclined conveyor, put the inclined conveyor into the container, reduce the pressure inside the container, and then release the support pins to form an assembly in which the adhesive layer is interposed between the transparent plates. This method of manufacturing a laminate is characterized in that the assembly is then heated to a heat sealing temperature or higher, and then pressure bonded.

Since the assembly is then heated and pressed to produce a laminate, a laminate without bubble defects can be produced. In addition, in the present invention, in order to form an assembly by overlapping one transparent plate to which an adhesive layer is attached and the other transparent plate in a reduced pressure container so that the adhesive layer is on the inner surface, the adhesive layer is One transparent plate attached,
Or, the other transparent plate is placed leaning against the inclined conveyor, and the lower end of the other transparent plate is aligned with the lower end of the transparent plate leaning against the inclined conveyor, and the upper end thereof can be operated from outside the evacuated container. By locking the supporting pins, the transparent plates are placed on the inclined conveyor with a space between them, and after the inclined conveyor is placed in the evacuated container, the supporting pins are locked. You can accomplish this by removing it. Further, the present invention provides that after forming an assembly in a reduced pressure container as described above, the container or the inclined conveyor is rotated so that the conveyor is horizontal, and the assembly is heated in the container to a temperature higher than the heat sealing temperature. and then sending the assembly between a pair of clamping rolls by the horizontally inclined conveyor,

Assemble. Next, the airtight chamber 20 is rotated to bring the tilted assembly device K into a horizontal position as shown in FIG. The assembly 12 is then heated below the temperature limit of the plastic board and above the heat sealing temperature of the thermoplastic adhesive layer, and then, for example,
A set of rubber rolls 14 is used to crimp the assembly. The compressed laminate is introduced into the atmosphere in the take-out zone 11 to reach atmospheric pressure, and then taken out from the airtight chamber. Then, if necessary, the laminate is autoclaved to obtain a laminate without bubbles inside.

い合せガラス板を取出した。Example 2 A 0.76 mm polyvinyl butyral sheet of the same size was placed on the adhesion side surface of one of two 2 mm x 1320 mm x 660 mm glass plates by heating at 7 locations using a soldering iron, and fixing those portions to the glass plate. Next, these two glass plates were placed on the assembly device K, moved into the airtight chamber 20, and heated to below about 80°C.
The pressure was reduced to 100 torr, pins 7A and 7B were removed, and the laminated glass was assembled. The laminated glass assembly was then heated to about 135° C. and pressed together using a pair of rubber rolls 17 at a pressure of about 1.5 kg/cm 2 (G). This was opened to the atmosphere in the removal zone 11, and a laminated glass plate without any remaining bubbles was taken out.

層体の製造方法。[Scope of Claims] 1. A method of manufacturing a laminate by forming an assembly in which an adhesive layer made of thermoplastic resin is interposed between a plurality of transparent plates, and heating and pressurizing the assembly, wherein the adhesive layer Place one of the transparent plates to which it is attached, or the other transparent plate, against the inclined conveyor, and align the lower end of the other transparent plate with the lower end of the transparent plate leaning against the inclined conveyor, and then place the upper end of the transparent plate against the inclined conveyor. By locking to a support pin that can be operated from outside the container to be depressurized, the transparent plates are placed on the inclined conveyor with a space between them and the adhesive layer facing inside, and the inclined conveyor is moved into the container. After reducing the pressure inside the container, the support pins are unlatched to form an assembly in which the adhesive layer is interposed between the transparent plates, and then the assembly is heated to a temperature higher than the heat sealing temperature. A method for producing a laminate, which comprises: and then crimping. 2 After forming the assembly, rotate the container or the inclined conveyor so that the inclined conveyor is horizontal, heat the assembly above the heat sealing temperature, and then move the assembly to the horizontal position.
