Definitions
- This invention relates to the improvement of the manufacturing technology of the plate glass by the overflow downdraw method.
- FPD flat panel displays
- liquid crystal displays plasma displays
- organic EL displays plate glass used in various fields is free from surface defects and waviness. The reality is that strict product quality is required.
- the overflow downdraw method is widely used as a method for producing plate glass.
- molten glass Gm is poured into the overflow groove 2 at the top of the molded body 1, and the molten glass Gm overflowing from both sides of the overflow groove 2 is placed outside the substantially wedge-shaped molded body 1.
- the sheet glass G is continuously formed by fusing and integrating at the lower end 4 of the molded body 1 while flowing down along the surface portion 3 (having the vertical surface portion 3a and the inclined surface portion 3b).
- the feature of this manufacturing method is that both the front and back surfaces of the formed glass sheet G are molded without contacting any part of the molded body 1 in the molding process. It is in the point which becomes the fire-making side without.
- the molded object 1 has the guide wall part 5 in each of the width direction both ends (for example, refer patent document 1 and patent document 2). Both ends in the width direction of the molten glass Gm overflowing from the overflow groove 2 are guided downward along the end surface of the guide wall portion 5 when reaching the outer surface portion 3 of the molded body 1.
- both ends in the width direction of the sheet glass G are sandwiched from both the front and back sides by a pair of edge rollers (cooling rollers) 6 for the purpose of suppressing contraction in the width direction of the sheet glass G.
- the width-direction both ends Gb of the glass sheet G are easier to cool than the width-direction central part Ga, and the temperature is low, so the separated glass sheets G are naturally fused. hard. Therefore, as shown in FIG. 13 a, a part of the width direction both ends Gb of the plate glass G is separated immediately under the molded body 1 due to the influence of the space X. In this state, as shown in FIG. 13b, when the width direction both ends Gb of the glass sheet G are sandwiched between the edge rollers 6, the separated portion is forcibly closed, and a cavity Y is formed in the inside.
- the cavity Y is formed in the ear portion or in the vicinity thereof.
- the cavity Y is also referred to as an ear cavity, and the ear cavity Y can be formed continuously or intermittently along the longitudinal direction (vertical direction) of the glass sheet G.
- the ear cavity Y is present, problems are likely to occur when the glass sheet G flowing down from the molded body 1 is cut. That is, as shown in FIG. 14, when the sheet glass G flowing down from the molded body 1 is broken along, for example, a scribe line along the alternate long and short dash line L in the figure, cracks that should develop on the scribe line are As indicated by arrows A and B, the glass sheet G propagates upward and / or downward along the ear cavity Y, and the glass sheet G may be damaged over a wide range. In particular, if the crack propagates upward through the ear cavity Y as indicated by the arrow A, it affects the vicinity of the molded body 1 and causes a serious trouble.

This includes the case where the angle between the tip and the lower end of the molded body is 5 degrees or less (the same applies hereinafter).
- the tip of the protruding piece has a tapered shape that is sharper than the lower end of the molded body.
- the molded body is usually formed of a fire-resistant brick such as dense zircon, and if the lower end of the molded body is sharp, the molded body may be damaged starting from chipping at the lower end. Therefore, as shown in an enlarged view in FIG. 12, it is customary that the lower end of the molded body has a rounded shape with rounded corners. However, when the lower end of the molded body is rounded as described above, the molten glass easily peels before reaching the lower end of the molded body. Therefore, as described above, if the tip of the protruding piece has a tapered shape that is sharper than the lower end of the molded body, the molten glass can be more reliably guided to the tip of the protruding piece.
- a fire-resistant brick such as dense zircon
