Abstract

In a manufacturing method for a glass panel with a gasket, an elastic member is placed on a table, and a multilayer glass panel is placed thereupon. A die is pressed against a top surface of the multilayer glass panel, thereby compressing the elastic member and glazing gasket molding material together with adhesive ejected from the application nozzle and applied to the top surface of the multilayer glass panel.

Claims

1. A manufacturing method for a glass panel with a glazing gasket for ejecting glazing gasket molding material together with adhesive from an application nozzle onto a periphery of a top surface of the glass panel that is facing upwards and placed on a table, the glass panel and the application nozzle being moved relative to one another to apply the glazing gasket molding material, the method comprising:

placing an elastic member on the table, the elastic member being made from an elastically deformable material;

placing the glass panel on the elastic member; and

applying the glazing gasket molding material to the top surface of the glass panel by ejecting the glazing gasket together with the adhesive slanting downward from an outlet to the rear in a direction of movement of the application nozzle, while a portion of the application nozzle in which the outlet is formed is pressed against the top surface of the glass panel to compress the elastic member.

2. The manufacturing method for a glass panel with a glazing gasket according to claim 1, wherein the glazing gasket molding material is applied by starting at an application starting point located on the fixture plate and by finishing at an application finishing point located on the fixture s late the method further comprising:

detachably attaching a fixture plate to a portion of the periphery of the top surface of the glass panel so that the fixture plate is immoveable,

applying the glazing gasket molding material together with the adhesive to the periphery of the top surface of the glass panel,

cutting portions on the fixture plate that include the application starting point and the application finishing point with a laser, and removing the portions that include the application starting point and the application finishing point together with the fixture plate from the surface of the glass panel, and

bonding a glazing gasket molding body with adhesive to a portion on the top surface of the glass panel where the portions that include the application starting point and the application finishing point have been removed, the glazing gasket molding body having a same cross-sectional shape as the glazing gasket molding material applied to the top surface of the glass panel.

3. A glazing gasket molding apparatus for ejecting glazing gasket molding material together with adhesive from an application nozzle onto a top surface of a glass panel that is facing upwards and placed on a table, the glass panel and the application nozzle being moved relative to one another to apply and attach the glazing gasket molding material together with the adhesive onto the periphery of the top surface of the glass panel, the apparatus comprising:

a table for placing the glass panel;

an elastic member made from an elastically deformable material placed on the table;

an application nozzle to eject the glazing gasket molding material together with the adhesive from an outlet slanting downwards;

a contacting device for pressing a portion of the application nozzle in which the outlet is formed against the top surface of the glass panel that is placed on the elastic member and fixed in position; and

a moving device for moving the glass panel and the application nozzle relative to one another so that the glazing gasket molding material is ejected from the outlet to the rear in a direction of movement of the application nozzle along the periphery of the top surface of the glass panel.

4. The glazing gasket molding apparatus according to claim 3, further comprising:

a fixture plate detachably attached to a portion of the periphery of the glass panel so that the fixture plate is immoveable; and

a laser cutting device for cutting the glazing gasket molding material, wherein

the fixture plate includes two mutually opposing plate portions and a connecting plate portion that connects ends of the plate portions,

the two plate portions are formed from a material that is impenetrable by the laser emitted from the laser cutting device,

when the periphery of the glass panel is positioned between the two plate portions, the glass panel is sandwiched between the two plate portions, and the fixture plate is detachably attached to the glass panel so that the fixture plate cannot move, and

one of the two plate portions is disposed on a portion of the periphery of the top surface of the glass panel.

5. The glazing gasket molding apparatus according to claim 4, wherein the fixture plate has a C-shaped cross-section that includes a mutually opposing first plate portion and a second plate portion, and a connecting plate portion that connects the ends of the first and second plate portions,

a length that the first plate portion projects from the connecting plate portion is greater than a length that the second plate portion projects from the connecting plate portion, and

the first plate portions is disposed on a portion of the periphery of the top surface of the glass panel.

6. The glazing gasket molding apparatus according to claim 3, wherein an inclined surface that gradually separates from the glass panel toward a front-of the glass panel is formed to the front in the direction of movement of a portion of the application nozzle that is pressed against the top surface of the glass panel.

7. The glazing gasket molding apparatus according to claim 4, wherein an inclined surface that gradually separates from the glass panel toward a front of the glass panel is formed to the front in the direction of movement of a portion of the application nozzle that is pressed against the top surface of the glass panel.

8. The glazing gasket molding apparatus according to claim 5, wherein an inclined surface that gradually separates from the glass panel toward a front of the glass panel is formed to the front in the direction of movement of a portion of the application nozzle that is pressed against the top surface of the glass panel.
