Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for producing ceramic tiles that are colored in multiple colors, particularly three or more colors, using colored powders.

Conventionally, it has been possible to easily manufacture multi-colored products, for example, two or less colors, but it has been possible to apply three or more colors only in the case of special patterns.

For example, patent No. 815077, which is an invention of the present applicant,
These are No. 822216 and No. 877648.
Of course, in other conventional colored tile manufacturing, the press part of the tile forming machine supplies the colored powder, fills the body powder, and then performs pressure molding, which limits the color of multicolored patterns. There were flaws that were made. In the present invention, by supplying colored powder for a colored pattern onto a single patterning board at a location other than the press section, it is possible to create patterns using a large number of types of colored powders, which can then be finalized. This is a method in which the main body powder of the tile is piled up in the press section and then pressure-formed.In order to create patterns using the various colored powders mentioned above, one patterned plate is placed in the press section of the tile molding machine. While passing through the running road body, a printing section consisting of a predetermined pattern plate and a colored powder supplying device for the pattern is provided at the same number of places as the colored powder, and the one sheet is printed. A multicolor pattern is sequentially formed on the patterning board according to the change in color, and this is attached to the press section of the tile forming machine.
This is an apparatus in which tile body powder is filled on top of the tile body powder, pressure molded, and integrally molded together with the various colored powders on the patterning plate and the tile body powder to form a multicolor patterned tile.

Next, the present invention will be explained in detail using embodiments shown in the drawings. In FIG. 1, a running track body 1 formed in a circular shape on a machine base (not shown) moves intermittently in the direction of arrow a, and a tile forming machine is installed at one location on the running track body 1. A press section 2 is provided, and 6

are formed, and the first printing press 4, the second printing press 4a, the third printing press
The printing press 4b, the fourth printing press 4C, and the fifth printing press 4d are each fixed to a machine stand and provided except for the press section 2.

Each of the guide frames 3... has a patterned plate 5 supported by an appropriate removable support member 5' (only one location is shown) and rotates together with the traveling track body 1. It's summery.

The first to fifth printing machines 4 to 4d each have pattern plates 6, 6a, 6b, 6c, and 6d on which different punching patterns 6', 6'a, 6'b, 6'c, and 6'd are formed. are provided in close proximity to the upper surface of the running road body respectively, and each pattern board 6 to
Colored powder boxes 8, 8a, 8b, 8c, and 8d containing colored powders 7, 7a, 7b, 7c, and 7d are slidably provided on 6d by piston devices 9, 9a, 9b, 9c, and 9d, respectively. There is.

Furthermore, push-up bodies 10 are provided below each of the pattern plates 6 to 6d.
(Only the pattern board 6 is shown and the rest are omitted) is provided at a position that does not interfere with the running of the running road body 1.

The patterning plate 5 attached to the guide frame 3 temporarily stops when it reaches the position of the first printing press 4 due to the rotation of the traveling track body.
At that time, the push-up body 10 rises.

(See Figures 2 A-D below.) With this rise, the patterning plate 5 is pushed up and comes into close contact with the lower surface of the patterning plate 6, and then the colored powder square 8 is slid on the patterning plate 6 by the piston device 9. . Then, the colored powder 7 in the colored powder box 8 is filled according to the cut-out pattern 6'' of the pattern board 6. When this filling is completed, the push-up body]
0 descends, a colored pattern 11 made of the filling powder is printed on the patterning board 5 and supported by the support 5''.

Then, the running track body 1 starts rotating and stops directly below the second printing machine 4a, and the punched pattern formed on the pattern board 6a is removed by the same operation as that performed by the first printing machine 4. 6″a
Accordingly, the patterning board 5 is printed with colored powders 7a of different colors, which are sequentially printed on the third printing machine 4b and the fourth printing machine 4b.
The printing machine 4C and the fifth printing machine 4d are sequentially printed, and a multicolor pattern 11'' of five colors is printed, and the patterning board 5 is sent to the press section 2.The press section 2 section is, for example, a third
As shown in the figure, a tile formwork 2 is provided below the running track body, and a bottom mold 13 that can be raised and lowered is provided on this.
An upper mold 13'' which is raised and lowered into the formwork 12 from above the running track body 1, and a flour chamber 15 for storing the tile body powder 14 are provided on the apron 16.

As mentioned above, when the patterning board 5 reaches the position of the press section 2 on which the five-color multicolor pattern 1'' is printed, the bottom mold 13 rises to support the patterning board 5, and the support body 5'' is removed. The patterning board 5 is supported by the bottom mold 13, and as the bottom mold 13 descends, the patterning board 5 is guided into the mold frame 12 and stops together with the bottom mold 13 at a predetermined position.

Next, the powder chamber 15 containing the main body powder 14 slides on the apron 16 by the piston device 17 and moves onto the patterning and patterning plate 5. Meanwhile, the main body powder 14 falls from the powder chamber 15 and moves onto the patterning plate 5. The above-mentioned upper mold 13'' descends into the formwork 12 as the powder chamber 15 returns, pressurizes the main body powder 14 in the formwork 12, and the multicolor pattern 1'' is supplied onto the multicolor pattern 1''. The colored powder of pattern 1 is also pressed, and this is combined with the main body powder 14 to form a tile T with a multicolored pattern.

However, the tile T is pushed out of the mold frame 2 by the rise of the mold 13'' and the rise of the bottom mold 3, and the tile T is taken out.The main powder 14 is supplied onto the patterning plate 5. ,
Since the colored powder is poured diagonally onto the multicolored pattern 11'', there is a concern that the pattern of the colored powder on the patterning board 5 may collapse.

It is a good idea for the boundaries of the pattern to be a little blurred, but if you want to make the boundaries clear, as shown in Fig. This problem can be solved by gradually pulling out the bottom cover plate 16'' with the piston device 18 after placing it on the multicolored pattern 11'' so that the powder body 14 falls almost at right angles onto the multicolored pattern 11''. In the embodiment shown in FIG. 5, the traveling road body is fixed so that only the patterned board 5 can run on it, and in the running direction there are Sixth (in this embodiment, six-color patterning is shown).

) Printing machines 4 to 4n are constructed on a running path, and parts corresponding to those in FIG. 1 are designated by the same reference numerals and explanations thereof will be omitted. Thus, the patterning board 5 may be sent manually or semi-automatically to the first to sixth printing machines in order, or preferably fully automatically, for example, the presence of the patterning board 5 in the second printing machine 4a is confirmed. The detection device and the device for feeding the patterning board 5 in the first printing press 4 to the second printing press 4a are connected to the first to final printing presses 4 to 4n or the press section 2 by a well-known automatic feeding device. It may also be performed in a sequential and fully automatic manner. In the embodiment shown in Fig. 5, it is easy to increase or decrease the number of printing presses, but in the embodiment shown in Fig. 1, the pitch of all printing presses must be changed, so it is difficult to increase or decrease the number of printing presses. It is.

If some of the above-mentioned colored powders are used as a colored glaze, the area will become slightly concave after firing, resulting in a different pattern.Also, even if recesses are formed on the surface of the patterned plate in advance, the tile surface It is possible to make unevenness appear on the surface, and also obtain shades of color.

Furthermore, if an anti-slip agent or the like is mixed into the irregularities or the colored powder, a non-slip multicolored patterned tile can be obtained. As described above, in the present invention, a multicolor pattern is printed in powder form on a patterned board in advance, and this is done outside the press section of the tile forming machine, so it is easy to adjust the patterning operation.
The molding time is also faster and more effective than when using a conventional press.
