And an apparatus. Disclosure of the invention
- the method for manufacturing a sheet glass of the present invention is a method for continuously forming a molten glass lipon supplied on a fixed bed composed of a plurality of supports into a sheet glass, the method comprising:
- the body is formed of a base material of a material capable of containing a liquid therein, or is formed in a structure capable of containing a liquid therein.
- the fixed bed is a fixed bed in which a plurality of the supports are arranged in a state where they are not moved in a direction parallel to a moving direction of the glass lipon.
- the amount of vapor released from each of the grooves in accordance with the glass temperature distribution in the moving direction of the glass lipon moving on the fixed bed. Is adjusted to form the glass ribbon into a sheet glass.
- the groove in the present invention includes a gap in addition to a literal groove.
- a fixed bed in which the support does not move in a direction parallel to the direction of movement of the glass lipon means that the support is only fixed in the direction of movement of the glass repone and may move in other directions. Means that.
- the glass temperature becomes lower toward the downstream side. This is based on the knowledge that a glass temperature distribution is generated in the direction, and this is a factor that deteriorates the surface smoothness in the moving direction of the formed sheet glass.
- the amount of steam generated from the upstream support located in the glass ripon portion having a high glass temperature is different from the amount of steam generated from the downstream support located in the glass ripon portion having a low glass temperature.
- the thickness distribution and the vapor film pressure distribution of the thin film of the vapor film on the upstream side and the downstream side of the glass lipon are formed, so that the surface smoothness in the moving direction of the formed sheet glass is deteriorated.
- the fixed bed is a fixed bed in which a plurality of support members are arranged in a state in which the support members do not move in a direction parallel to the moving direction of the glass lipon, and a vapor film is provided between the support members.
- a fixed bed was used in which grooves for releasing vaporized vapor of the forming agent were formed.
- the groove width can be set freely for each groove, and the glass ribbon can be set for each support. Since the length in the moving direction can be freely set, a suitable configuration for allowing steam to escape can be set.
- the amount of steam released from each groove was adjusted in accordance with the glass temperature distribution in the moving direction of the glass ribbon moving on the fixed bed. Further, by using a fixed bed, it is possible to ensure that the landing point of the glass lipon supplied on the support does not coincide with the groove position. As a result, it is possible to improve the surface smoothness of the formed sheet glass in the moving direction, and to prevent generation of streaks in the sheet glass.
- the adjustment of the amount of vapor released from each groove is performed by setting the length of each support in the glass lipon moving direction to be the same, and viewing the width of the groove from the moving direction of the glass lipon. This is done by making the downstream side narrower than the upstream side.
- the upstream side where the glass temperature of the glass ribbon is high and the amount of steam generated from the support is large the groove width is wide and steam easily escapes, and the glass temperature of the glass ribbon is low and the downstream where the amount of steam generated from the support is small is small.
- the narrower the groove the more difficult it is for steam to escape.
- the thickness and the vapor film pressure of the vapor film formed between the substrate and the support are made uniform. Thereby, the surface smoothness in the moving direction of the formed sheet glass is improved.
- the amount of steam released from each groove is adjusted by setting the width of each groove to be the same and the length of the support in the direction of movement of the glass lipon in the direction of movement of the glass repone. This is done by making the downstream side longer than the upstream side.
- the number of grooves per unit length in the length direction of the glass ribbon on the fixed bed increases as the glass ribbon glass temperature increases and the amount of steam generated from the support increases, and the number of grooves increases. Therefore, the thickness of the steam film formed between the glass ripon and the support on the upstream side and the downstream side and the steam film pressure are equalized because the steam flow rate is low and the downstream side where the steam generation amount is small is reduced. Thereby, the surface smoothness of the formed sheet glass in the moving direction can be improved.
- the supports are arranged such that the landing point of the molten glass ribbon supplied onto the support does not coincide with the position of the groove. This can be achieved by providing the support with a fixed floor, thereby preventing the generation of streaks in the sheet glass.
- a continuous thin sheet glass manufacturing apparatus of the present invention is an apparatus for continuously forming a molten glass lipon supplied on a fixed bed made of a continuous support into sheet glass.
- the support is formed of a base material made of a material capable of containing a liquid therein, or is formed in a structure capable of containing a night body therein.

And between the supports Serial vapor film forming agent, characterized in that the grooves vapors to escape vaporized is formed respectively.
- the fixed bed has a structure in which the support is parallel to the moving direction of the glass lipon. Since a plurality of glass ribbons are arranged in a state where they do not move, the landing position of the glass ribbon can be reliably positioned so that the molten glass lipon supplied to the support does not fall into the groove. As a result, no streaks are formed in the formed sheet glass.
- the production apparatus of the present invention by providing a positioning roller for positioning a landing position at which the glass ripon lands on the fixed floor, the glass ripon wraps around the peripheral surface of the positioning opening and lands on the support. , Landing impact can be reduced.
- the positioning roller is formed of a base material of a material capable of containing a liquid therein or formed of a structure capable of containing a liquid therein.
- the vapor film forming agent which is a gas having a temperature equal to or higher than the glass transition point, is introduced in a liquid state, and the vapor film forming agent comes into contact with the glass repone through a thin layer of the vaporized vapor film. I ca n’t put it on.
