Embodiment Construction

[0044] Hereinafter, modes for implementing the present invention will be described with reference to the drawings, but the present invention is not limited to the embodiments described below, and various modifications and substitutions can be added to the following embodiments without departing from the scope of the present invention.

[0045] figure 1 It is a side view of the glass plate manufacturing apparatus provided with the glass ribbon conveyance apparatus which concerns on one Embodiment of this invention. In this float glass manufacturing apparatus, the molten glass obtained in the glass melting furnace 1 is supplied onto the molten tin in the molten metal tank 2 to form a glass ribbon 5 in a ribbon shape. After the formed glass ribbon 5 is lifted from the molten metal tank 2 by lifting rollers and taken out, it is transported by the glass ribbon conveying device and slowly cooled to below the strain point temperature of the glass in the slow cooling furnace 3, and th...

Abstract

The invention relates to a glass ribbon transporting device, a glass plate manufacturing device and a glass plate manufacturing method. The glass ribbon transporting device comprises a plurality of transporting rollers for transporting a band-plate-shaped glass ribbon; a moving mechanism for moving anyone out of the plurality of transporting rollers towards the glass ribbon along the axial direction of the transporting rollers; and an approaching / separating mechanism for driving the above one transporting roller to approach the glass ribbon or to move away from the glass ribbon. At least two transporting rollers out of the plurality of transporting rollers are different in roller diameter.

Description

technical field [0001] The present invention relates to a glass ribbon conveying device, a glass plate manufacturing device, a glass plate manufacturing method, a method for specifying a flawed conveying roller, and a method for preventing the occurrence of flaws in a glass ribbon. Background technique [0002] In a glass sheet manufacturing device based on the float method, molten glass melted in a glass melting furnace is supplied onto molten tin in a molten metal tank to form a strip-shaped glass ribbon, and the formed glass ribbon is passed through a lift roller from the After the molten metal tank is lifted out, it is slowly cooled in the slow cooling furnace to below the strain point temperature of the glass, and then cooled in the cooling glass tempering furnace to a temperature that can be cut, and cut into a specified size by a cutting device. [0003] In the said glass plate manufacturing apparatus, the glass ribbon conveyance apparatus is installed in a slow cooli...
