2. Description of the Related Art As a method of forming a color pattern on an automatic glass molding machine, a printing method has been widely used. However, although the printing method is suitable for mass production, the printed color patterns naturally have a uniform impression, and there is a feeling that the paint has a different texture and lacks luxury. Another drawback is that the transparency of glassware is impaired.

Next, the glassware W is taken out and transferred onto the intermittently driven conveyor 4 as shown in FIG. Conveyor 4
A coloring device 5 is installed at an intermediate position of, and an appropriate amount of powder of colored glass or color frit is supplied to the bottom surface of the stopped glassware W. The distinction between colored glass powder and color frit powder is not clear, but it is common to call low-melting glass containing a large amount of colorant a color frit, and when you want to form a dark pattern. It is preferable to use a color frit. The particle size may be adjusted according to the pattern to be formed, but if the particle size exceeds 1 mm, it becomes difficult to fuse and the particle size is 1 mm or less, more preferably 1.
It is preferable that the thickness is 00 μm or less.

In this embodiment, the coloring device 5 includes a nozzle 7 having a solenoid valve 6 and drops a fixed amount of powder from a position close to the bottom surface of the glassware W to the bottom surface. If the tip and the bottom surface of the nozzle 7 are too far apart from each other, they may not be properly placed on the bottom surface and may be scattered around. The nozzle 7 can be moved relative to the bottom surface of the glassware W to form a pattern of a specific shape. As described above, since the bottom surface of the glassware W is heated in the previous step, the dropped powder adheres in a semi-molten state. It is also possible to arrange a plurality of coloring devices 5 at a plurality of positions of the conveyor 4 and supply powder of colored glass or color frit of different colors to form a multicolor pattern.

Next, as shown in FIG. 3, the glassware W is transferred to another apparatus having a pan 9 on the upper end of a large number of rotating shafts 8 and is heated again by a plurality of burners 10 while being rotated.
The heating is performed for about 15 to 25 seconds, and the powder of the colored glass or the color frit placed on the bottom becomes molten glass and is fused to the bottom of the glassware W to form a color pattern. Since the series of steps described above proceed while the glassware W is in a high temperature state immediately after molding, there is no risk of damage due to local heating, and there is no waste of energy for heating. Then, the glass container W is conveyed to a slow cooling furnace, and is slow cooled by a conventional method. Due to this slow cooling, the strain generated due to local heating is removed, and a finished product is obtained.

In the above-described embodiment, the bottom surface is heated while rotating the glassware W as shown in FIG. 1. However, when it is desired to form a color pattern on the side surface of the glassware W, the glassware W is used.
Only a specific surface on the side is heated with a burner without rotating. Then, as shown in FIG. 4, colored glass or color frit powder is supplied from a close position and adhered to the heated specific surface.

In FIG. 4, colored glass or colored frit powder is dropped by the coloring device 5 onto the glassware W held laterally by the holder 11. Since the powder adheres to the side surface of the heated glassware W, after that, as in the above-described embodiment, the powder may be further heated by a burner to be fused and then gradually cooled. The method of holding the glassware W sideways is arbitrary, and the bottom may be chucked, for example.

Next, the blue color frit powder was dropped in small circles from the coloring device 5 and attached to the bottom surface. The color frit used is a low melting point glass having a high boric acid content, to which cobalt oxide is added in an amount of about 30% by weight, and the particle size thereof is about 50 μm. The supply amount of the color frit powder per glass cup is about 1 g. Since the melting point of this color frit powder is about 650 ° C., the color frit powder adhered to the bottom surface of the high temperature glass cup in a semi-molten state.

When this was heated again with a burner for 20 seconds to raise the bottom surface temperature to 900 ° C., the color frit powder was completely melted into circular blue glass, which was fused to the bottom surface of the glass cup. This was gradually cooled to obtain a high-grade transparent glass cup having a blue circular pattern on the bottom as shown in FIG.

As described above, according to the method of the present invention, it is possible to apply an arbitrary color scheme on any surface of an automatically machined glassware without impairing the transparency and high-grade feeling of the glassware. Any color pattern can be formed. Moreover, this color pattern is different from the one obtained by coloring the glass itself and the one obtained by printing, which is very effective in giving a variety of designs to the automatically molded glassware.
In addition, since coloring is performed while the glassware is in a high temperature state immediately after molding, there is no fear of damage even if local heating is performed, and there is an advantage that energy for heating can be minimized.
