摘要： PURPOSE:To improve production efficiency by subtracting the tare of the glass melting device from the total weight of the device including glass to obtain the glass weight, then obtaining the glass outflow from its variation and controlling the temp. of the flow rate part. CONSTITUTION:When in batch operation, the weight WF of the empty glass melting device A is weighed by a load cell 13 and inputted to a controller 15. The tare WF is then subtracted from the weight WT of the device A changed with glass and set, and the flow rate QS of molten glass per unit time is set. The glass material from a feeder 16 is charged in a specified amt., a glass crucible 1 is heated to melt the material, and an outflow pipe 4 is heated by a heater 10 to discharge molten glass 3. The total weight WT of the device A including glass is measured, and the tare WF is subtracted therefrom to obtain the glass weight WG. The process is repeated, the variation in glass weight WG is calculated to obtain loss in weight per unit time, and the outflow Qp is also obtained. The heater 10 is controlled by the outflow part temp. control part 19 so that the outflow Qp and set value Qs are equalized. Since the entire device including glass is weighed in this way, sampling is not needed, and the production efficiency is not decreased.

摘要： PURPOSE:To automatically reheat glass which has been hardened by reduction of temperature of primary molding before secondary molding, by detecting softened state of glass in a reheating tank and controlling revolving speed of blowing rod and timing of pulling out the blowing rod from a furnace depending upon the information of the softened state of glass. CONSTITUTION:Glass having wound shape before primary molding or glass 7 hardened by reduction of temperature by passing through primary molding process is inserted into a heating tank 2 of a tempering furnace 1 and reheated. During the operation, softened state of glass is detected by a sensor 10 and the detected information is inputted to a controller 12. The controller 12 calculates revolving speed of the blowing rod and timing of pulling out the blowing rod from the furnace, regulates revolution of a servo motor (control device of glass attitude) 9 and and pulls out the blowing rod from the furnace by order signal based on the result of the calculation.

摘要： Provided is a device for manufacturing glass gob by dropping a molten glass droplet into a drop adjusting member and by dropping the fine droplet of the molten glass having passed through a through hole, into a receiving portion. The temperature of the drop adjusting member is controlled to suppress the temperature change which is caused at the beginning of the operation of the manufacturing device, thereby to suppress the mass dispersion or the dropping position dispersion of the fine droplet of the molten glass to pass through the through hole of the drop adjusting member.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a glass molded body which enables to stably produce a high quality glass material, using low stability (high crystallizability) glass species, high specific gravity, high refractive index glass or the like, by continuously pouring molten glass into a mold.SOLUTION: In the method for producing a glass molded body in which molten glass accumulated in a vessel 1 is allowed to flow down through a glass outflow pipe 2 connected to the vessel 1, continuously poured into a mold disposed below the pipe, and molded, a pipe provided with an outflow section with a glass outlet port at one end and a narrowed section 4 which leads molten glass to the outflow section and has an inside diameter smaller than that of the outflow section is used as the glass outflow pipe 2. Molten glass is allowed to flow out after increasing the diameter of a molten glass flow flowing in the pipe in an inverse tapered pipe section 5, and the molten glass is poured into the mold while keeping the level of molten glass in the mold lower than the outlet port of the pipe.
