CONSTITUTION:Starting materials for general-purpose glass mosaics are melted in a kiln at a high temp. The prepd. sufficiently homogeneous molten base material G is allowed to flow out 1, horizontally drawn in the form of a belt, introduced into the gap between the 1st die roll 2 and the 2nd die roll 3, and patterned under rolling to obtain a beltlike continuously formed body S1 for glass mosaics having longitudinal and lateral thin parts 4, 5. The formed body S1 is conveyed C to a slow cooling furnace R, where it is slowly cooled to relieve internal stress and strain, and both edges of the formed body S1 are trimmed 6 along the parts 4 with trimming rolls H0. The resulting continuously formed body S2 is successively broken along the parts 5 with the 1st breaking roll H1, and the laterally broken strips 7 are broken along the parts 4 with the 2nd breaking rolls H2 to obtain glass mosaic units U.

Description

[Detailed description of the invention] The present invention relates to a method for manufacturing glass mosaics.

As is well known, the conventional method for producing glass mosaics has been mainly manual production methods. That is, for example, 11ti! using a crucible kiln! There are two methods: production in small quantities in units of iJ, or molding by removing seeds from a tank kiln and molding them with a mechanical press.

With this method, there are problems in that production efficiency is poor and costs are high when making ordinary crow mosaics, except when very special shapes, patterns, etc. are required.

This invention was made with the aim of solving these conventional problems, and involves drawing out a molten base from a tank kiln and rolling it with a pair of mold rollers to form a series of glass mosaics. Form this in advance)
The present invention provides a method for manufacturing a glass mosaic, which involves cutting the glass mosaic in an inner thin layer to obtain a single glass mosaic.

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figure 10 is an enlarged plan view of the X part of Figure 2, and Figure 11 is an enlarged plan view of the X1 part of Figure 2.
Figure 2 is a cross-sectional view of the roll-out machine shown in Figure 1 from X1l-XI to wide dog. This shows another implementation of the foot. Note that the same parts are designated by the same reference numerals A and J throughout the figures.

First, the configuration will be explained. This invention consists of the following five steps. In other words, (1) After adjusting the particle size of general-purpose glass mosaic raw materials to a size that is easy to dissolve, they are mixed in the usual quantity ratio (product glass waste (current) in an appropriate ratio according to the requirements) (2) A glass melting step in which a glass melting material G is placed in a wide tank kiln 1 (Fig. 1) to obtain a sufficiently homogeneous molten base G free of impurities and air bubbles. The molten material G is drawn out horizontally in a strip by flowing out from the material outlet 1 of the tank kiln T, and then passed through the first type roller 2 and the second type roller 3.
It is guided to a roll-out machine M (see Fig. 2) consisting of 4. A series of thin-walled lattice-shaped parts (see FIGS. 3, 5, and 12) to obtain a strip-shaped crow mosaic continuous molded body S1 by molding to be breakable in
(3) The glass mosaic series S1 is placed on a roll conveyor C and guided to an annealing process, where the stress and strain inside the formed body S can be taken out. (4) Paris 6 (Fig. 3) on both sides of the strip-shaped glass mosaic continuous molded body S□ which has reached at least the slow cooling range of 7 m degrees;
A glass mosaic continuous molded body S is formed by dropping it along the vertical thin wall portion 4 with a deburring roller H0 made of an elastic body.
2 (see Figures 4 and 5) and the crow mosaic continuous molded body S2 with +51 burrs 6 removed.
A first breaking roller H1 made of an elastic material sequentially breaks the horizontally thin portion 5 to form a horizontally broken piece 7 (see Fig. 7), and then the horizontally broken piece 7 is broken by a second breaking roller made of an elastic material. The glass mosaic is broken along the vertical thin wall portion 4 at H2 to obtain a single glass mosaic U.

Here, the melting temperature of the raw material in the tank kiln T is 13
() It is generally 0 to 1550°C. Melted base G
The viscosity is preferably about 10 3 to 10 4 poise, which is suitable for molding in a continuous molding process. Najaku, tank kiln TK, s-kerutl is an on-off valve for the substrate outlet 1.

As shown in Figures 10 to 12, the 1-type roller 2 is a type roller that forms the back side of the single glass mosaic U, that is, the bottom half of the bottom side. is the mold roller that forms the half. ,,l!
The engagement between the first type roller 2 and the second type roller 3 is as follows.
The meshing state is as shown in FIG. 12. That is, in order to form vertical and horizontal inner thin inner parts 4 and 5 in the glass mosaic continuous molded body S1, each mold roller 2 and 3 is used.
A gap g corresponding to the thickness of the thin-walled portions 4 and 5 is provided between each of the ridges 2a and 3a so that they mesh with each other.

Therefore, when the molten cord G is formed by the first and second rollers 2 and 3 that are driven and rotated in the direction of arrow a,
The single glass mosaic unit U is joined together by the thin wall portions 4' and 5 to form one continuous band-shaped molded body, that is, a continuous glass mosaic molded body S1. These thin-walled parts 4 and 5 are formed during the slow cooling step 2 to change the shape of the strip-shaped compact to its 'fX'.
Although it has a strength of 11ifi to hold it, it is thick enough to easily break with just a small amount of force applied during the breaking T process.

The first type roller 2 has sole feet 8 of a single glass mosaic U.
A protrusion 9 is provided to form a ridge (Fig. 13). This protrusion 9 is not limited to the pattern shown in Figure 10,
For example, protrusions may be provided to form the chevron-shaped soles shown in FIG. 14 and the lattice-shaped soles shown in FIG. 15.

The slow cooling furnace R is a long-length furnace, and its length varies depending on the size and shape of the glass mosaic. It is usually in the range of 10 to 30 m. The temperature gradient in the longitudinal direction inside the furnace is determined by parameters such as the heat capacity of the crow mosaic, the supplied heat, or the speed of the roll conveyor C. The temperature range for slow cooling is usually about 400 to 450°C. It is desirable that the glass mosaic continuous molded body S1 be cooled at one time so that it can be handled by hand in the lehr (Kawaguchi).

As shown in Fig. 4, the deburring roller H consists of a feed roller 10 and a back roller I+, and is driven once in the direction indicated by the arrow. Then, the edge 6 of the glass mosaic continuous formed body S1 after the forming surface is fixed to the collar I of the presser roller 11.
It is pressed by the force 1a, breaks at the vertically thin portion 4, and is removed as shown in FIG. - Side 1 breaking roller H1 has groove 12
The receiver with a is made up of a stand 12 and a suppression roller 13. The glass mosaic continuous molded body S2 fed from the deburring roller H9 is pushed to the base 1 by the pressing roller 13.
Since it is pressed from above by 78 l 2 a of No. 2, it is broken at the horizontally thin portion 5.

As shown in FIGS. 1 and 8, the second breaking roller H2 is a pair of upper F feed rollers 14 driven in the direction of arrow C.
．． 15, and independent protrusions 16 are provided at each mouth to lar 14 and 15. The protrusions 16 are provided at intervals of every other vertically thin-walled part 40 of the glass mosaic continuous molded body a, and the upper and lower feed rollers 14,15 mutually slide the protrusions 16 into the vertically thin-walled part. It's a 1 horizontal alignment so that there is a 4 in 1 fall. Therefore, when the horizontally broken pieces 7 are now fed into the second temporary cutting roller H2, they are broken at the vertically thin portions 4 and divided into single glass mosaic units U. FIG. 9 shows this state.

i! Figure 41.6 shows an example in which the sole of a single glass mosaic is formed with crow beads 17 without being molded.

The glass beads 17 may be introduced before the molten base material G is fed into the rollout machine M.

As explained above, the present invention (dXX) involves forming a continuous molded object of crow mosaic by pulling it out of a dXX bath-melting field earth tank kiln and rolling it with a pair of mold rollers, and then forming a continuous molded object of a crow mosaic into two vertically thin-walled objects formed in advance during the forming process. Since the structure is such that a single glass mosaic is obtained by breaking at a portion, it is possible to continuously manufacture a large amount of glass mosaic, and it is possible to improve production efficiency and reduce costs.
