Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, when a glass plate for an automobile such as an automobile door glass or backlight glass is formed from the base glass, the base glass is automatically broken according to the cutting line put in the base glass. The present invention relates to a glass plate folding apparatus that can cause a new (break) as shown in a cut line in order to make it easy to break.
[0002]
[Prior art]
As shown in FIG. 3, the glass plate folding device used in the conventional folding method includes a belt conveyor device 36 having a belt 32 that supports the glass plate (raw glass) 12 in a plane, and an upper portion of the belt 32. And an end cutting and pressing device 35 that moves in an XY orthogonal coordinate system or a polar coordinate system.
[0003]
In the conventional folding method, a mold plate 33 cut inside the belt 32 and cut on the belt support plate 34 according to the cut line made on the glass plate 12 is arranged to form a step. The glass plate 12 is placed on the belt 32 with the cut line superimposed on the template 33. In this state, the glass plate 12 is first cut off by the glass plate folding apparatus shown in FIG. It is pressed into the mold as it is stepped.
[0004]
[Problems to be solved by the invention]
By the way, nowadays, automobiles are becoming more and more expensive, and accordingly, glass plates for automobiles are gradually becoming thicker (5 mm to 6 mm thick).
[0005]
When the glass plate 12 becomes thicker, even if the cutter pressure is increased and a cutting line is made in the glass plate 12, new entering (progress of cracks) is not sufficiently performed, and automatic splitting by the glass plate splitting device shown in FIG. In some cases, it does not break well according to the cutting line, and sometimes cracks do not occur and the part remains.
[0006]
In the conventional folding method described above, the glass plate to be broken is simply placed on the template via a belt and forcibly pushed, so the cutting line is sufficiently filled with “new”. If a thick glass plate is supplied, it may not break even if it is pushed or split, or chipping may occur and good breaking may not be performed. Even if the polishing operation is performed, a good product cannot be produced, and scratches such as chipping may remain.
[0007]
Therefore, the present invention does not require a template for placing a glass plate for breaking along the cutting line as in the conventional folding method, and in addition, a glass plate with insufficient new content is supplied. However, it is intended to provide a glass plate folding apparatus that first performs a new inserting operation and then performs the folding.
[0008]
Further, the present invention is a glass plate folding apparatus that performs a new inserting operation again even when a thick glass plate is not sufficiently inserted into a new glass so that it can be broken without error in a good new entering state. Is to provide.
