【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、板ガラスｔ−製造するための装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to an apparatus for producing flat glass t-.

ガラスとする。Conventionally, as a method for producing relatively thin plate glass, there is a method as shown in FIG.
Publication No. 235). The molten glass 11 is made to flow out from a slit provided at the bottom of the melting tank 12, and the molded body 1 is placed below.
3, the flow is separated, and then merged at the lower end to form a plate glass.

わめて効率が悪い。However, in the method described above, the glass is
The width of the flow contracts as soon as it moves away from it. As a result, the bulges (bead edges) generated at both ends are cut off, and only the flat part at the center edge is used for practical use. The cut-off side ends account for 20 to 30% of the total width of both ends, which is extremely inefficient.
この欠点を解決する手段として、例えば特公昭４６−２
４９０９号公報、特公昭５０−２６１１号公報に記載さ

くなり、玉縁の形成が抑えられる。As a means to solve this drawback, for example,
4909 and Japanese Patent Publication No. 50-2611 have been proposed. This uses an overflow molded body 2G as shown in FIG. 4 to make the molten glass flow out of the slit at the bottom of the melting furnace and supply it to the molded body, and the glass flowing into the upper opening groove 21 is , overflows over the groove walls and flows down both sides with both ends in contact with the guide edges 22. At this time, at the lower end, the width direction side end flows along the surface of the guide protrusion 23, so the horizontal component of the flow effectively increases along the guide edge 22, and the downward plate-like flow increases. An outward pulling force is created against the flow. As a result, the side edges become thinner and the formation of beading edges is suppressed.

のを防ぐ作用をする。The molten glass supplied to the top of the molded body spreads completely to the guide walls on both sides 9, flows down both sides, and merges at the bottom end to form 1.
It becomes a sheet of glass. At this time, at the lower end of the molded body, the protrusions serve to spread both ends of the flow outward and prevent it from shrinking inward.

下端部は成形体１の下方に突出している。The guide wall 2 has a structure in which front and back guide walls are connected together at the lower end of the molded body 1, and the connected lower end portions protrude below the molded body 1.

状に取付けてるる。A fin-shaped protrusion 3 is arranged at the boundary between the lower end of the guide wall 2 that protrudes below the molded body and the lower end of the molded body. The protruding body 3 has a triangular shape, and is mounted substantially symmetrically on the left and right sides with its two sides in contact with the inner wall of the lower end of the guide wall and the lower end of the molded body.

態で流下する。To the top of the molded body 1, a homogeneous molten glass 4 without bubbles or foreign matter and without striae is supplied in a wide band shape from, for example, a slit at the bottom of the melting tank as shown in FIG. The molten glass 4 that has flowed down from the top of the molded body 1 is applied to both the front and back surfaces IA, I.
B, the liquid flows completely along the surface of the molded body 1 to the guide walls 2 on both sides 9, and flows down while contacting the guide walls 2.

では１０酎とした。As the molten glass 4 flows down along the surface of the molded body 1, the width of the flow tends to be narrowed due to surface tension. On the other hand, the guide wall 2 has the function of preventing the width of the flow from narrowing because the flowing molten glass always comes into contact with and wets the guide wall 2. The left and right guide walls are arranged so that the distance between them gradually narrows toward the bottom of the molded body, but this allows for smoother flow than arranging them straight down. It is desirable. In this example, while the distance between the left and right guide walls at the top of the molded body 1 is 310 m, this distance is reduced to 2 at the bottom end.
It was set at 99w. Note that the left and right guide walls should not approach one side toward the other, but should approach equally on the left and right sides in a symmetrical manner. Generally, the difference in the distance between the left and right guide walls at the upper and lower ends is approximately 10 to 20 mm, and if it exceeds 30 mm, the formed glass sheet will have thicker side edges9.
The rim becomes larger. In addition, both guide walls 2 are made to extend vertically downward substantially in parallel at the lower end portions protruding from the lower end of the molded body. Further, the height of the guide wall 2 was set to 10 mm in this example.

適当であシ、本実施例では、２００ ｔｍに設定した。The height of the molded body 1 is determined based on the following conditions: the maximum thickness of the molded body slightly below the top is 30 m, the viscosity of the flowing glass is t-10 poise, the thickness of the plate glass to be molded is 1.1, and the pulling amount is 18 Kp. /hr is suitably 175 to 250 m, and in this example, it was set to 200 tm.

It is set appropriately depending on the thickness of the molded body 1, the viscosity of the glass, the amount of pulling, etc. The surface of the molded body 1 is coated with platinum, and the inside is filled with a fireproof heat insulating material 5 such as foamed alumina.

are merged at the lower end of the molded body 1 to form one sheet of glass. The viscosity of the molten glass at this time was 10 to 10 poise. This glass is then continuously drawn downward and cooled by a roll (not shown in FIG. 1) located at a suitable location below, such as roll 14 shown in FIG. It becomes plate glass.

とした。In this embodiment, the protruding body 3 has a right triangular shape with two sides touching the lower end of the molded body and the inner wall of the lower end of the guide wall protruding vertically downward from the lower end of the molded body. Extend the wall diagonally to the bottom of the molded body,
It may be fixed so that its two sides are in contact with the inner wall of the lower end portion and the lower end of the molded body, and there is no problem even if it does not form an exact right triangle. The two sides that sandwich the right angle are both 3 in this example.
0 garden, but the ratio of the two sides may deviate slightly from 1:1. Also, the hypotenuse does not necessarily have to be a straight line,
For example, the protrusion 3' shown in FIG. 2 may have a curved shape. In this example, the thickness of the protruding body 1 is 1 ml.
And so.

The order was 20-230. On the other hand, in the case where the protrusion 3t is not provided, the total plate width is 180 to 200 rta, and the effective width is 120 to 1.
In the 40th area, the effectiveness of protrusion 3 was confirmed.
