Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for supplying glass gobs for obtaining glass products separated into two colors using an automatic molding machine using a continuous tank furnace.

(Prior art) Colored layer 16 as shown in Fig. 3 and no coloring! Glass products such as the two-colored glassware 17 or plates and pots have a high design effect and are very popular products in the market. As a method for manufacturing glass products separated into these two colors, a method called so-called artificial blowing is known. In this method, glass products separated into two colors are produced individually using a double-wrap method in which colored glass is further wrapped around a base glass product.

(Problem to be solved by the invention) However, in the case of the method of manufacturing glass products separated into two colors by artificial blowing, it is difficult to mass produce or the cost of the product is extremely high. Therefore, there has been a strong desire to develop a method for producing glass products separated into two colors using an automatic molding machine using a continuous tank furnace.

(Means for Solving the Problems) The present invention provides a method for supplying glass gobs for obtaining glass products separated into two colors using an automatic molding machine using an A-type tank furnace that can solve these conventional drawbacks. The glass base material stirred and melted by the first feeder and the colored glass base material stirred and melted by the second feeder having a color feeder structure are fed into four containers between the first feeder and the second feeder. This system is characterized by feeding glass gobs separated into two colors from the tip of the connected feeder into a connected feeder that becomes a single feeder.

(Function) Fig. 1 is a plan view of the feeder provided in the present invention, Fig.
The figure shows a sectional view taken along line A-A in FIG.
The feeder 2 is a second feeder, and 3 is a connected feeder that connects the first feeder l and the second feeder 2 to form one feeder.

The glass base melted in the furnace body (not shown) is guided into the first feeder 1 and fed into the connected feeder 3 at a constant speed by the rotation of the starter 4.

On the other hand, the glass substrate guided into the second feeder 2 consisting of the color flint feeding machine 5
The frit supplied from the molten glass and the stirrer for stirring the frit form a uniformly colored molten glass base, which is fed into the connected feeder 3 at a constant speed by the rotation of the stirrer 7.

Connected feeder 3 is a ml feeder! and the second feeder 2 intersect on a line that bisects the angle of both feeders, so that the glass substrate in the first feeder 1 and the glass substrate in the second feeder 2 are from the same angle. It is configured to be guided into the connected feeder 3. Also, from the intersection of the first feeder l and the second feeder 2, I[i18
is provided to prevent the glass substrates of both feeders from colliding with each other and stirring and mixing the two substrates. Furthermore, the temperature of the glass substrate 9 in the first feeder 1 fed by the starter 4 and the temperature of the glass substrate 9 in the second feeder 2 fed by the stirrer 7 are determined.
The temperature inside each feeder is adjusted so that the temperature is almost the same as that of the two in the connected feeder 3.
so that the flow rate of the two molten glass bases is constant.
] Arrangements have been made.

In this way, the glass base supplied from the first feeder 1 and the colored glass base supplied from the second feeder 2 are moved within the connected feeder 3 while maintaining a separated state without being equally stirred and mixed. It is sent into the spout ll. A long nose feeder 12 made of platinum material is installed at the tip of the spout 11 so as to align with the center line of the connected feeder 3, and from the tip of the long nose feeder 12, a glass gob 1
3 will be supplied.

FIG. 4 is an enlarged view of the glass gob 13 in FIG. 2.
This is a cross-sectional view, in which the glass blank 14 supplied by the first feeder I and the colored glass blank I5 supplied by the second feeder 2 are separated into halves. The glass gob 13 thus separated into two colors is then continuously fed into a mold according to the usual method, and the glass gob 13 separated into two colors, a colored layer 16 and an uncolored layer 17, as shown in FIG. 18 will be continuously and automatically molded.

As is clear from the above explanation of the operation, the supply force 11 of the glass gob according to the present invention is achieved by connecting the glass substrate of the first feeder 1 and the colored glass substrate of the second feeder 20 to the connected feeder 3 under certain conditions. At the same time, in the connected feeder 3, the glass gobs 13 separated into two colors are fed into the spout 11 in the same state without stirring or mixing.
'-It is something that provides.

In addition, although the drawing shows a case where the molten glass base material supplied from the furnace main body is supplied as it is with the "first feeder 1" having a normal configuration, the first feeder 1 is replaced with the color feeder JRa&L like the second feeder 2. It is also possible to feed the glass gob 13 separated into two colors consisting of two colored bases by introducing a color frit with a different coloring effect into the second feeder. Furthermore, as the color frit to be fed into the color feeder, any conventional technique (all known as frits) can be used, and it goes without saying that the coloring conditions can be arbitrarily set according to the desired glass product. .

(Example) Using a feeder with a glass substrate flow rate of 25 tons/day as shown in FIG. 1, glass pots 18 separated into two colors as shown in FIG. 3 were produced. Flint glass was melted in the furnace main body, and Cr-containing color frit was fed into the second feeder 2 at a rate of 0.8% of the outflow amount of the second glass substrate 1O.

As a result, the glass gob 13 separated into two colors, green and colorless and transparent, is fed from the tip of the long nose feeder 12, and then the glass gob is fed into the mold of the blur λ machine to produce green and colorless glass gobs. Continued production of glass cups separated into two colorless colors.

(Effects of the Invention) As is clear from the above explanation, the method for supplying glass gobs according to the present invention enables continuous production of glass products separated into two colors, which conventionally could only be produced individually by artificial blowing. It enables continuous production with an automatic molding machine using a type tank furnace, and compared to conventional artificial products, it can be mass-produced extremely easily and achieves a significant reduction in product cost. is possible.

As described above, the present invention has various effects and greatly contributes to the development of the glassware manufacturing industry.
