[0032] First, the overall structure of the glass manufacturing apparatus which concerns on this embodiment is demonstrated. figure 1 It is a schematic diagram which shows an example of the structure of the glass manufacturing apparatus 200 of this embodiment. The glass manufacturing apparatus 200 is provided with the melting tank 40, the clarification tank 41, the stirring device 100, the shaping|molding device 42, and the conduit|pipe 43a, 43b, 43c which communicates these components, respectively. The molten glass 7 generated by the melting tank 40 flows into the clarification tank 41 through the conduit 43a, and after being clarified by the clarification tank 41, flows into the stirring device 100 through the conduit 43b, is stirred into homogeneity by the stirring device 100, flows into the forming device 42 through the conduit 43c, and The glass ribbon 44 is formed by a down draw method.

[0093] The operation of the stirring device 300 according to the second embodiment will be described with reference to the drawings. In addition, this embodiment is the same structure as 1st Embodiment except that the stirring member 302 is a structure demonstrated below.
[0094] Figure 10 It is a perspective view which shows the stirring member 302 of the stirring apparatus 300 of this embodiment. The stirring member 302 includes a columnar shaft member 305 for axial rotation, and blades 306 a , 306 b , 306 c , 306 d , and 306 e provided on the side surfaces of the shaft member 305 . The blades 306a to 306e are provided so as to extend in the radial direction of the shaft member 305 . The shaft member 305 is arranged in the chamber 301 so that its rotation axis is vertical. The chamber 301 has the same structure as that of the first embodiment. The shaft member 305 is positioned relative to the chamber 301 through the same positioning process as that of the first embodi...
Embodiment approach
[0140] The present invention is not limited to the above-described embodiments, but may be implemented in various forms.
[0141] can also be as Figure 16 As shown, the blades of the stirring member include: a longitudinal bar-shaped first wing 506 extending in the axial direction of the shaft member 505; Second Wing 507. That is, the stirring member may be a crank type stirring member. exist Figure 16 2 shows two first wings 506, but the number of first wings 506 may be one or more than three. Moreover, in Figure 16 2 shows a plurality of second wings 507, but the number of second wings 507 should be at least one. like Figure 16 As shown, a disk-shaped third wing 508 extending from the shaft member 505 may be further provided in a direction perpendicular to the shaft member 505 , but the third wing may not be provided. Even by positioning such a stirring member in the same manner as in the first embodiment, the shear stress to the molten glass can be locally increa...
