本考案は、ガラス壜等の成形機にゴブ（ガラス
塊）を供給するガラス塊供給装置における撹拌装
置に関する。[Detailed Description of the Invention] The present invention relates to a stirring device in a glass gob feeding device that supplies gobs (glass gobs) to a molding machine for glass bottles and the like.
ガラス壜等の製造技術において、製品肉厚の均
一化、製品の均質化を図るためには、成形機に均
一な温度のゴブを供給することが、最も重要であ
るが、ゴブ温度を均一にする技術は非常に難しく
いまもつて確立されていないのが実情である。 In manufacturing technology for glass bottles, it is most important to supply a gob with a uniform temperature to the molding machine in order to make the product wall thickness uniform and the product homogeneous. The reality is that the technology to do so is extremely difficult and has not yet been established.
即ち、ガラス塊供給装置の温度制御だけでは、
到底ゴブ温度の均一化を期待できないため、従来
よりガラス塊供給装置内で溶融ガラスを撹拌する
方法が採られているが、このような手段をもつて
しても、ゴブの温度を均一にすることは実際上非
常に困難であつた。これは、次のような理由によ
るものである。 In other words, if only the temperature control of the glass gob feeding device is enough,
Since it is impossible to expect the temperature of the gob to be uniform, the conventional method has been to stir the molten glass in a glass lump supply device, but even with this method, it is not possible to uniformize the temperature of the gob. This was actually extremely difficult. This is due to the following reasons.
即ち、従来のガラス塊供給装置は、第１図に示
すように、スパウトボウル１内に、上下位置を調
節することによつて、溶融ガラスの流量を調整す

ータ１２とチユーブ１０下端部間にある程度の距
離があるので、チユーブ１０下端部を経て送り出
されるゴブと離れた位置で溶融ガラスの撹拌が行
なわれることになり、これがゴブの不均一な温度
分布を招く要因となつていたのである。 That is, as shown in FIG. 1, the conventional glass gob supply device includes a tube 10 that adjusts the flow rate of molten glass by adjusting the vertical position in a spout bowl 1, and a tube 10 located on the outer periphery of the tube 10. Since there is a certain distance between the stirring rotor 12 and the lower end of the tube 10, the molten glass can be stirred at a position away from the gob sent out through the lower end of the tube 10. This caused uneven temperature distribution in the gob.
しかも、上記の従来装置においては、チユーブ
１０と撹拌ロータ１２との二重構造を呈するため
装置構造がかなり複雑であり、しかも、これらが
煉瓦等の耐火物製で機械的強度が比較的小さいの
に加えて、撹拌ロータ２が筒壁に上下に長い切欠
１２ａを有する三叉状に形成されている関係上、
撹拌作用時に撹拌ロータ１２の足１２ｂが切損し
やすいといつた欠点があつた。 Furthermore, the conventional device described above has a double structure of the tube 10 and the stirring rotor 12, so the structure of the device is quite complicated.Moreover, these devices are made of refractory materials such as bricks and have relatively low mechanical strength. In addition, since the stirring rotor 2 is formed in a trident shape with vertically long notches 12a in the cylindrical wall,
A drawback was that the legs 12b of the stirring rotor 12 were easily broken during stirring.
本考案は、このような現状に鑑みてなされたも
のであつて、ゴブの温度をできる限り均一化して
製品肉厚の均一化、製品の均質化を図り得る構造
簡素で故障の発生も少ないガラス塊供給装置にお
ける撹拌装置を提供することを目的としている。 The present invention was developed in view of the current situation, and it is a glass with a simple structure and less occurrence of failure, which can make the temperature of the gob as uniform as possible, thereby making the thickness of the product uniform and the product homogeneous. The object is to provide a stirring device in a lump feeding device.
以下、本考案の実施例を第２図以降の図面に基

In the figure, 1 is a spat bowl, 2 is a heat insulating material, 3 is a metal spat casing, 4 is a burner tile, 5 is a cover, and 6 is a heat insulating powder. 7 is an inlet for the molten glass into the sparto bowl 1, and 3 is an orifice ring disposed at the lower end of the outlet formed on the bottom surface of the sparto bowl 1. Inside the spurt bowl 1, by moving up and down as shown by the arrow,
A pair of plungers 9 are provided to send out molten glass as gobs from the opening of the orifice ring 8, and a refractory tube 10, which is a feature of the present invention, is provided around the plungers 9.

て付根側程厚肉になつている。 The tube 10 is provided to be vertically adjustable and rotatable around its axis. By adjusting the vertical position, the gap between the lower end surface of the tube 10 and the bottom surface of the sparto bowl 1 is adjusted, thereby melting While it is configured to adjust the flow rate of glass, a stirring protrusion 11 is provided on the outer periphery of the lower end to serve also as a stirring rotor. As shown in FIGS. 2 and 3, the stirring protrusions 11 are provided radially protruding from the outer periphery of the lower end of the tube 10.
It has a front surface (front surface in the rotational direction) S 1 that protrudes from the outer circumferential surface of the tube 10 in the direction of the rotational radius, and an inclined rear surface (rearward surface in the rotational direction) S 2 , and becomes thicker toward the root side in plan view. ing.

均一化できるのである。 According to the above configuration, the tube 10 that adjusts the flow rate of the molten glass is also used as the stirring rotor, so that the molten glass is stirred at a position close to the outlet of the spart bowl 1, that is, at the very end of the gob position. This means that the gob temperature can be equalized because it is done in close proximity.

By providing the stirring protrusion 11 on the tube 10, the lower surface of the stirring protrusion 11 is placed a distance l (preferably about 4 mm) from the lower end surface of the tube 10 so as not to increase the adhesive area of the hardened glass. ) located above. Further, in order to facilitate the above-mentioned replacement, it is desirable that the maximum diameter A of the stirring protrusion 11 portion be set to be equal to or smaller than the diameter B of the upper end flange portion 10a of the tube 10. The stirring protrusion 11 is not limited to the shape shown in FIGS. 2 and 3,
As illustrated in FIGS. 4 to 7, various cross-sectional shapes can be set, and as shown in FIG. 8, it may be formed in a spiral shape. Further, as shown in FIGS. 9A and 9B, the protrusions 11 may be provided in two stages, upper and lower, with the upper and lower stages being out of phase.

るのである。 The present invention has the above-mentioned configuration, and a stirring protrusion is provided on the outer periphery of the lower end of the refractory tube that adjusts the flow rate of molten glass by adjusting the vertical position.
Since the tube is also used as a stirring rotor, the molten glass is stirred near the location where the gob becomes, making it possible to equalize the temperature of the gob, making the product wall thickness uniform, and the product homogenized. It is possible to achieve this.
