US 2014/0144569 A1 · Glass Panel with Glazing Gasket Manufacturing Method and Manufacturing Apparatus

Abstract

The technology provides for alignment of forming positions of glazing gaskets formed on both front and rear sides of a glass panel. After the glazing gasket has been formed on the multilayer glass panel, a first distance L1 is measured from the reference member to the glazing gasket. After the multilayer glass panel has been reversed and positioned at the reference position for the glass panel, a second distance L1′ is measured from the reference member to the glazing gasket. An offset amount of the forming position of the glazing gasket on the rear side of the multilayer glass panel is determined from the difference of the first distance L1 and the second distance L1′. An application starting position of the application nozzle when forming the glazing gasket on the rear side of the multilayer glass panel is corrected based on the offset amount.

Dependent claims

A method of manufacturing a glass panel with a glazing gasket in which the glazing gasket is formed along a preset glazing gasket forming position on a periphery of a first face of a rectangular glass panel by ejecting glazing gasket molding material in a constant shape together with an adhesive from an application nozzle while at least one of the application nozzle and a work table on which the glass panel is placed is moved, wherein the glass panel is reversed and the glazing gasket is formed along a preset glazing gasket forming position on a periphery of a second face of the glass panel, thereby forming the glazing gasket on both sides of the glass panel, the method comprising:

calculating a difference between the glazing gasket forming position on the first face viewed from above, after two orthogonal sides of the glass panel have been positioned at a reference position for the glass panel on the work table with the first face facing upward and the glazing gasket has been formed on the first face of the glass panel, and the glazing gasket forming position on the second face viewed from above, after the glass panel has been reversed and placed on the work table with the second face facing upward and the side opposite a first side of the two orthogonal sides and the side opposite a second side of the two orthogonal sides have been repositioned at the reference position for the glass panel;
determining an offset amount for the preset glazing gasket forming position on the second face of the glass panel based on the difference;
and
correcting the application starting position of the application nozzle based on the offset amount when forming the glazing gasket on the second face of the glass panel.
