200804209 九、發明說明： 【發明所屬之技術領域】 本發明係關於一種玻璃成形品製造裝置及玻璃成形品之 製造方法。 【先前技術】 先前，用作光學元件等之原材料之玻璃預成型件（玻璃 坯、玻璃塊、玻璃成形品），係利用熔解裝置來熔解原料 玻璃，並使熔解所得之熔融玻璃成形為適當之尺寸，由此 而獲得。 作為玻璃預成型件之製造過程中所使用之熔解方法，已 知有連續熔解及間歇熔解。對於連續熔解，由於可連續進 灯玻璃原料之投入、溶解、澄清、及攪拌各個步驟，因而 適於大量生產玻璃預成型件等情形。另一方面，對於間歇 熔解，由於其係於單一之熔解罐中間歇地進行玻璃原料之 技入溶解、澄清、及攪拌，因而適於生產總生產量較少 之玻璃預成型件等情形。 所於玻璃預成型件之製造中，重要的是，高精度地製造均 質且具有固定光學特性之玻璃預成型件。因此，除選擇適 當之破璃原料之外，在原料玻璃之熔解、澄清、及攪拌階 段，亦需要進行各種考慮。尤其於利用間歇熔解來供給熔 融玻璃時，由於原料玻璃並非連續地熔解，因此易產生氣 泡、條紋等或失透，故成為玻璃預成型件之光學特性不穩 定之原因。為解決上述問題，先前採用有下述方法，即， 使用具有螺槳翼之攪拌器具，使熔融玻璃產生對流，以進 118918.doc 200804209 行攪拌等方法（參照專利文獻i )。 [專利文獻1]日本專利特開平2_252626號公報 【發明内容】 [發明所欲解決之問題] 然而，近年來，在能夠製造口徑小之玻璃預成型件時， 會產生以前未遇之問題。 即，生產口徑小之玻璃預成型件時，於每單位時間内熔 融玻璃之消耗量較少之玻璃製造過程中，由於以長時間成 形暫時溶解之熔融玻璃，因此熔融玻璃長時間置於已熔解 之狀態下，導致熔融玻璃中會產生條紋等，由此產生損害 熔融玻璃之均質性之問題。 其原因在於，由於溶融玻璃之組成物之比重不同，致使 融玻璃不均勻，或者由於溶融玻璃中之部分成分揮發， 致使熔融玻璃表面附近之熔融玻璃之組成不均勻。 將以上述方式所產生之熔融玻璃維持其中條紋而直接送 至玻璃成形裝置進行成形，藉此使摻有條紋之玻璃預成型 件成形，結果，生產出折射率等光學特性異常之玻璃預成 型件。繼而，可將上述現象稱為本發明之課題。 本發明係鑒於如上所述之課題創作而成，該課題係提供 一種玻璃成形品製造裝置及玻璃成形品之製造方法，可在 使原料溶融以製造玻璃成形品時，製造出所產生之條紋等 缺陷較少之玻璃。 [解決問題之技術手段] 於玻璃之熔融成形過程中，產生如上所述之條紋或失透 118918.doc 200804209 現象之原因未必明確。然而，本發明者等可獲得以下見 解，即，使熔融玻璃流過引導路徑時之溫度梯度條件等亦 為其要因之一。 因此’本發明者等發現，對連接於使原料溶融之熔融槽 且將使原料熔融所形成之熔融玻璃引至流下裝置之引導路 徑進行加熱控制，以使於遍及引導路徑之長度方向上成為 特定之溫度狀態，由此可使熔融玻璃及該熔融玻璃成形後 之玻璃成形品均質化，以完成本發明。 (1)一種玻璃成形品製造裝置，其具備：熔解裝置，具有 使原料溶融而形成熔融玻璃之熔融槽、及連接於熔融槽且 使融玻璃從溶融槽中流出之引導路徑；流下裝置，使經 由引導路徑而流出之熔融玻璃流下；玻璃成形裝置，具有 使所流下之炼融玻璃成形之複數個成形模具；以及引導路 徑控制裝置’對引導路徑進行溫度控制，以使引導路徑之 溫度順著熔融玻璃之流動方向而變低。 發明（1)之玻璃成形品製造裝置具備：熔解裝置，具有使 原料溶融而形成熔融玻璃之熔融槽、及連接於熔融槽且使 炼融玻璃從溶融槽中流出之引導路徑；流下裝置，使經由 引導路徑而流出之熔融玻璃流下；玻璃成形裝置，具有使 所流下之溶融玻璃成形之複數個成形模具；以及引導路徑 控制裝置’對引導路徑進行溫度控制，以使引導路徑之溫 度順著熔融玻璃之流動方向而變低。 假设從熔融槽流出之熔融玻璃流經引導路徑中時，若該 炼融玻璃之溫度非單調減少而是溫度增加之部分位於引導 118918.doc 200804209 路::據融玻璃中易產生氣泡、條紋或失透。 向流動方Γ月之方法，引導路經内部之溫度隨著炼融玻璃 生气、肖料而㈣降低，心在㈣玻心部難以產 生虱泡、條紋或失透。 厓[Technical Field] The present invention relates to a glass molded article manufacturing apparatus and a glass molded article manufacturing method. [Prior Art] A glass preform (a glass blank, a glass block, or a glass molded article) used as a material for an optical element or the like is melted by a melting device, and the molten glass obtained by melting is appropriately formed. Size, thus obtained. As the melting method used in the production process of the glass preform, continuous melting and intermittent melting are known. For continuous melting, it is suitable for mass production of glass preforms due to continuous steps of input, dissolution, clarification, and agitation of the glass material. On the other hand, in the case of intermittent melting, since it is intermittently subjected to the dissolution, clarification, and agitation of the glass raw material in a single melting tank, it is suitable for producing a glass preform having a small total production amount. In the manufacture of glass preforms, it is important to produce glass preforms that are homogeneous and have fixed optical properties with high precision. Therefore, in addition to the selection of suitable glass-making materials, various considerations are required during the melting, clarification, and agitation stages of the raw material glass. In particular, when the molten glass is supplied by the intermittent melting, since the raw material glass is not continuously melted, bubbles, streaks, or the like are easily generated or devitrified, which is a cause of instability of the optical characteristics of the glass preform. In order to solve the above problem, there has been previously employed a method of convecting molten glass using a stirring device having a propeller blade, and stirring it in a manner such as stirring (see Patent Document i). [Problem to be Solved by the Invention] However, in recent years, when a glass preform having a small diameter can be produced, there is a problem that has not been encountered before. That is, in the production of a glass preform having a small diameter, in the glass manufacturing process in which the consumption of the molten glass is small per unit time, since the molten glass which is temporarily dissolved is formed for a long time, the molten glass is left to be melted for a long time. In this state, streaks or the like are generated in the molten glass, thereby causing a problem of impairing the homogeneity of the molten glass. The reason for this is that the composition of the molten glass is not uniform due to the specific gravity of the composition of the molten glass, or the composition of the molten glass in the vicinity of the surface of the molten glass is not uniform due to volatilization of a part of the molten glass. The molten glass produced in the above manner is maintained in a fringe and directly sent to a glass forming apparatus for forming, whereby the striped glass preform is formed, and as a result, a glass preform having an abnormal optical property such as a refractive index is produced. . Then, the above phenomenon can be referred to as the subject of the present invention. In view of the above-mentioned problems, the present invention provides a glass molded article manufacturing apparatus and a glass molded article manufacturing method, which can produce defects such as streaks when a raw material is melted to produce a glass molded article. Less glass. [Technical means to solve the problem] In the process of melt forming of glass, the occurrence of streaks or devitrification as described above may not be clear. However, the inventors of the present invention have obtained the knowledge that temperature gradient conditions and the like when the molten glass flows through the guide path are also one of the factors. Therefore, the inventors of the present invention found that the guide path connected to the molten glass formed by melting the raw material and melting the raw material to the downstream device is heated and controlled so as to be specific to the longitudinal direction of the guide path. In the temperature state, the molten glass and the glass molded article after the molten glass is molded can be homogenized to complete the present invention. (1) A glass molded article manufacturing apparatus comprising: a melting device; a melting tank for melting a raw material to form molten glass; and a guiding path connected to the melting tank to flow the molten glass from the melting tank; and a flow-down device The molten glass flowing out through the guiding path flows down; the glass forming device has a plurality of forming dies for molding the molten glass to be circulated; and the guiding path control device controls the temperature of the guiding path so that the temperature of the guiding path follows The flow direction of the molten glass becomes low. The glass molded article manufacturing apparatus of the invention (1) includes: a melting device having a melting tank for melting a raw material to form molten glass; and a guiding path connected to the melting tank to flow the molten glass out of the melting tank; The molten glass flowing out through the guiding path flows down; the glass forming device has a plurality of forming dies for molding the molten glass flowing down; and the guiding path control device controls the temperature of the guiding path so that the temperature of the guiding path follows the melting The direction of flow of the glass becomes lower. It is assumed that when the molten glass flowing out of the melting tank flows through the guiding path, if the temperature of the smelting glass is not monotonously decreased, but the temperature increase is located at the guide 118918.doc 200804209 Road:: According to the molten glass, bubbles, streaks or bubbles are easily generated. Destruction. To the method of flowing the moon, the temperature inside the road is guided to be irritated by the smelting glass, and (4) is lowered, and the heart is hard to produce bubbles, streaks or devitrification in the center of the glass.

During convection agitation, the rotating shaft 142 is rotated, thereby rotating the propeller blades 144 to remove bubbles (defoaming) in the molten glass. When the fused glass is convected, the components retained in the partially molten glass are diffused into the entire molten glass by convection stirring, and as a result, a uniform molten glass can be obtained.

Specifically, in the case of a glass molded article having a small diameter, the amount of glass consumed by the mother unit is small, so that the molten glass is melted for a long time. As a result, the composition of the molten glass is partially separated due to the difference in the specific gravity of the composition of the molten glass, or I is caused by the composition of the partially molten glass, resulting in uneven composition of the molten glass near the surface of the molten glass. This produces streaks. A portion of the molten glass containing the stripes is sent to the cutting stirring chamber 124. By providing a barrier (not shown) at the boundary between the convection stirring chamber 122 and the cutting stirring chamber 124, it is possible to prevent the molten glass containing the streaks from flowing into the cutting and stirring chamber 124 in a large amount. The molten glass sent to the cutting chamber 124 is agitated by cutting off the stirring. The guiding path 200 is temperature-controlled by the guiding path control means such that the temperature of the guiding path 200 becomes lower along the flow direction of the molten glass. Specifically, in the case of direct heating, the guiding path control device adjusts the electric dust applied to the dice sheet 251 and the second reed sheet 2S2, thereby controlling the jth reed plate 251 and the second reed plate 252. The temperature between the straight down tubes 21〇. The guide path control device adjusts the voltage applied to the second reed plate 252 and the third crotch plate 253, thereby controlling the temperature of the linear down tube 210 between the second reed plate 252 and the third reed plate 253. . The guide path control device adjusts the voltage applied to the third blade plate 253 and the fourth leaf plate 254, thereby controlling the temperature of the steering tube 220 between the third leaf plate 253 and the fourth leaf plate 254. The guide path control device adjusts the voltage applied to the fourth reed plate 254 and the orifice reed plate 25 5 to thereby control the temperature of the downcomer 23 之间 between the fourth reed plate 254 and the orifice reed plate 255. In the case of indirect heating, in addition to this, temperature adjustment is performed by a temperature regulator such as a gas burner provided near the guide path. 118918.doc -38- 200804209 Thus, the molten glass which has become uniform after being cut and stirred in the cutting and stirring chamber 124 is maintained in its state, and is directly sent to the glass forming apparatus 400 through the guide path 200. The rotating shaft 425 is intermittently rotated at a fixed speed. Due to the rotation of the rotary shaft 425, the rotary table 422 supporting the rotary shaft 425 is rotated. The molding die 430 disposed on the rotary table 422 moves directly below the downflow tube 230 by the rotation of the rotary table 422. As shown in Fig. 10, when the molten glass is dropped from the downflow tube 230 to the molding die 430, as shown in Fig. 11, the molding die 430 and the molten glass c are kept non-ferrous by the pressure of the gas ejected from the molding die 43. The molten glass C is formed in a contact state. When the molten glass in the down tube 230 is dropped onto the molding die 430, the sensor (not shown) detects the molten glass C and rotates the rotary table 422, and the molding die 430 containing the molten glass C rotates with the rotary table 422. And move. As the rotary table 422 rotates, the molding die 430 moves from directly below the downflow pipe 230 toward the immediately below the first transfer device 500. During this period, the molten glass was formed into a curved body and cooled to form a glass molded article E. Specifically, the molten glass of the concave shaped surface 430a is gradually cooled and solidified to become a glass molded product E (also referred to as a glass blank, a glass block, a glass preform), and a gas ejected from the fine pores. The molten glass is floated at a position non-contact with the concave molding surface 43A. Further, when the temperature is drastically lowered during the forming process, the glass molded article E may be broken or damaged. In the above case, it is preferable to arrange a heating device in any part of the working time, and use the heating device to heat the forming device </ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ ̄ This does not cause a sudden drop in the temperature of the forming mold, and the result of the ^r field_h cow can reduce the defective rate of the glass molded article. Then, the opened glass molded article E of 4 4 i + 1 is recovered by the i-th transfer device 500. The first transfer device 500 includes adsorption handles 5〇3a and 5〇; 3b, 5〇3χ, and 5〇3d'忒 first transfer device 5〇〇, which adsorbs the glass molded article in the molding die, and the rotation axis is By rotating the center, the glass molded article is transferred to the conveying device 800. After the glass transfer product E is recovered by the first transfer device 500, the varnished molding die 430 can be moved to the flame irradiation position of the burner 45 0 again with the rotation of the rotary table 422, and by the burner 45 heating. The mold 450 of the molten glass is heated by the burner 450, the temperature difference between the molten glass C and the forming mold 430 is reduced, and the molten glass c is not cooled rapidly, so that the volume of the molten glass C can be prevented from changing rapidly. The glass which is cooled by the molten glass C is prevented from being cracked. In the state where the gas is ejected from the molding die 430, the molding die 430 and the k-melting glass C are kept in a non-contact state, and the molten glass c is cooled while being rotated. Therefore, the molding die 430 and the molten glass c are not The glass molded article E which has no contact marks on the surface of the glass after the molten glass C is cooled can be obtained. In the glass forming apparatus 400, during the production of the glass molded article e, in order to cool the rotating shaft 425 to prevent the rotating shaft 425 from being burnt, a cooling device 423 〇 may be provided and 'as long as the cooling device 423 is provided, even if the burner 450 is utilized 118918.doc -40-- 200804209 The addition, 430, and I functions as 430, and the rotation axis 425 is indirectly affected by #, and the movement of the rotary table 422 can be kept smooth. ', the person will be described in the action of the selection device 700. The glass transferred from the forming mold 43 by the first transfer device 5 is formed into a shape (10) E at a transfer position 86 on the conveyor belt 864 of the belt conveyor 860.

After the f-plate 862 is placed with four glass molded articles E, the f-type conveyor 860 drives a motor (not shown) and moves the transport f 864 for a specific time (specific distance), thereby transferring the pallet 862 to the shift W. Send position 864b. After the pallet 862 is transported to the transfer position 86413, the top plate 684 is moved in parallel such that the end portions of the four suction tubes 692 are positioned above the concave formation surface 862a of the pallet 862. Subsequently, after the glass molded article e is adsorbed and held by the suction pipe 692, the top plate 6 84 is moved in parallel so that the suction pipe 692 is positioned above the weighing device 710. The suction pipe 692 discharges the glass molded product E, and the glass molded product e is placed on the concave forming surface 710a of the weighing device 710, respectively. The weighing device 710 weighs the glass molded article E placed on the concave forming surface 710a. The weighing device 710 transmits an electric signal corresponding to the weight of the glass molded product E to the weighing display device 722. The weighing display device 722 for calculating the weight of the glass molded product E based on the electric signal determines whether or not the weight of the glass molded article E placed on the concave forming surface 710a is within a specific standard range. The glass molded article outside the standard range is discharged. After the operation of the vacuum pump 713, the suction pipe 692 is lifted and lowered, and the glass molded article E which has not been discharged, that is, the glass molded article E within the standard range is returned to the pallet 118918.doc -41 - 200804209 862. After the conveyance device 800 collects the glass molded article from the conveyed pallet 862, the glass molded article is transferred to the subsequent step. Fig. 12 is a view showing the relationship between the temperature of each of a plurality of temperature measuring points disposed in the rear of the guide path and the flow distance of the molten glass in the embodiment (Examples 1 and 2) of the present invention. Fig. 13 is a view showing the relationship between the temperature of each of a plurality of temperature measurement points provided in the guide path and the flow distance of the molten glass in the embodiment (Comparative Examples 1 and 2) opposite to the specification of the present invention. In Examples 1 and 2 and Comparative Examples 1 and 2, the temperature of the glass melting tank was 1200 QC', and the temperature at the end of the guiding path was the same, and was 93 °C. Further, in any of the examples, a platinum tube is used as a guiding path, and a temperature measuring device from No. 1 to No. 7 is provided in the platinum tube in the flow direction of the molten glass. No. 1 is located on the tight side of the outlet of the melting tank, and No. 7 is located at the end of the tube and is located near the joint with the orifice. The heating of the tube is controlled by direct heating and/or indirect heating, whereby the temperature profiles of Figures 12 and 13 are obtained. In the embodiment 1 of Fig. 12, the temperature of the guiding path monotonously decreases with the flow direction of the molten glass flow, and the gradient thereof gradually becomes gentle. The above temperature control is an ideal embodiment of the present invention. Further, in the second embodiment, the temperature of the lead cable in No. 6 increased only a little. In the glass produced in the aspects of Examples 1 and 2, any phenomenon such as bubbles, streaks, and devitrification did not occur, and thus it was suitable for the formation of an optical element. On the other hand, in Fig. 13, the temperature gradient of the guiding path in Comparative Example 1 gradually becomes larger. As described above, if it flows in the above-mentioned guide path 118918.doc -42 - 200804209 in the path of high temperature for a long time, a large amount of air bubbles are mixed in the obtained glass. Further, in Comparative Example 2, the temperature of the guiding path was excessively lowered and then it was suddenly increased. In this case, a large amount of devitrification occurred in the obtained glass, so that it could not be used as an optical glass. Further, the present invention is not limited to the above-described embodiments, and modifications, improvements, etc. within a scope that can achieve the object of the present invention are included in the present invention.
