Abstract

PROBLEM TO BE SOLVED: To provide a chamber for conveying capable of reducing the occurrence rate of defectives of flat glass produced by a floating method by providing a conveying roll and covering the peripheral surface of the conveying roll with an inert gas. SOLUTION: A chamber 10 for conveying a glass ribbon is equipped with a conveying box 11 arranged between a float bath 33 and an annealing furnace 38, a conveying roll 12 installed in the conveying box 11, a cover 13 having a C-shaped cross section and a pair of nozzles 14. An inert gas 15 such as nitrogen can be jetted from the nozzles 14. Thereby, the gas is filled along the peripheral surface of the conveying roll 12 without a fear for condensing or sticking tin vapor, a tin compound, etc., penetrated from the float bath 33 into the conveying box 11 to the peripheral surface of the conveying roll 12. As a result, problems such as reaction of the tin, tin compound, etc., sticking to the peripheral surface of the conveying roll 12 with oxygen can be eliminated by the chamber 10 for conveying the glass ribbon.

2. Description of the Related Art FIG. 3 shows a glass plate manufacturing apparatus 30 based on a float method. As shown in this figure, molten glass 32 melted in tank kiln 31 is molten metal 34 such as molten tin or molten tin alloy stored in float bath 33.
And is formed on the glass ribbon 35. The glass ribbon 35 moves from the upstream side (left side in the figure) to the downstream side (right side in the figure) on the surface of the molten metal 34, and is taken off by a transport roll 36 provided on the downstream side of the float bath 33. Is pulled up from the molten metal. The transport roll 36 is made of an iron-based metal, is housed in a transport box 37, and transports the glass ribbon 35 to the lehr 38. Annealing furnace 38
The glass ribbon 35 that has been gradually cooled in the above is drawn out of the annealing furnace 38 and then cut into a predetermined size to form a glass plate 39.

By the way, the molten metal 34 in the float bath 33 is in a high temperature state (about 500 ° C. to 1300 ° C.).
Therefore, the molten metal 34, the molten glass 32, N 2 and H 2 in the atmosphere, and a small amount of O 2 , H 2 O and S chemically react with each other to cause floating, generally called dross. Generate things. In addition, since the temperature is relatively low near the take-off point, the solubility of the molten metal 34 is reduced, so that a fine floating substance such as a metal oxide, for example, SnO 2 tends to be easily generated. As shown in FIG. 4, when pulling up the glass ribbon 35 from the float bath 33, the dross 40 is carried out by attaching to the lower surface of the glass ribbon 35,
May adhere to the surrounding surface.

Has a problem in that it adheres again to the lower surface of the glass ribbon 35 that is sequentially conveyed, causing spots, scratches, and the like, which significantly impairs the quality of the glass plate 39. Further, the dross 40 attached to the peripheral surface of the transport roll 36 reacts with the material of the transport roll 36 to form a convex portion, and there is a possibility that a concave portion or a scratch is generated on the lower surface of the glass ribbon 35.

Further, in general, the atmosphere of the float bath 33 contains tin vapor and a tin compound.
When the atmosphere of 33 infiltrates into the transport box 37, there is a possibility that tin vapor and a tin compound condense or adhere to the peripheral surface of the transport roll. In particular, if oxygen is contained in the atmosphere in the transport box 37, tin vapor, a tin compound and oxygen react on the peripheral surface of the transport roll 36, and tin or a tin compound adheres to the lower surface of the glass ribbon 35. In addition, there is a problem that a concave portion or a scratch is formed on the lower surface of the glass ribbon 35. Further, when tin vapor or a tin compound condenses or adheres to the peripheral surface of the transport roll 36, there is a problem that the life of the transport roll 36 is shortened.
