2. Description of the Related Art When a colored powder material is used in the conventional manufacturing of this type of multicolor pattern tile, a patterning die is inserted and a patterning metal is applied in a press molding section of a multicolor pattern tile manufacturing apparatus. In many cases, a series of steps of filling the mold with the colored powder material and removing the patterned mold are carried out, followed by press molding.

Further, as a method for supplying a colored powder material for producing a multi-colored pattern tile at a place other than the press molding section and an apparatus used for the method, there is a technique described in Japanese Patent Publication No. 59-52045. .

In this technique, a traveling road body is provided as a conveying means to a press molding section of a multicolor pattern tile manufacturing apparatus,
Along with the traveling direction of the traveling road body, a printing unit comprising a predetermined patterned plate and a colored powder supply means of a predetermined pattern is provided by the number of colors of the colored powder material, and a multicolored pattern is formed on one patterned plate. Are sequentially formed according to the change of the color pattern, this is mounted in the press molding part, the tile main body powder is filled on it, press molding of the multicolor pattern tile is performed, and then the patterned plate is removed. I am trying.

[0005]

Since the conventional manufacturing apparatus and manufacturing method for a multicolor pattern tile are configured as described above, a multicolor pattern tile can be put in and out in the press molding section. The method of forming a pattern by using the colored powder material described in (1) has a limited number of patterns and colors. Further, as a method related to this method, on the upper surface of the primary molded body obtained by primary press-molding the tile body powder in the press-molding section, a primary recess corresponding to the pattern is formed by the upper mold, and the primary recess is colored powder. Although there is a method of forming a multicolor pattern tile by filling it with a secondary press molding after this, it is also difficult to use a large number of colors in the press molding section in this method as well. Furthermore, in any of the above cases, press molding requires a considerable amount of time, which is not suitable for mass production.

[0006] As in the technique described in Japanese Patent Publication No. 59-52045, a multicolored pattern made of a colored powder material is formed in a printing form on a single patterned plate outside the press molding section, which is sequentially formed. The method of mounting in the press part and filling the tile main body powder on such a patterned plate has the advantage that the polychromaticity is increased and mass production can be achieved compared to the method of forming the pattern in the press molding part. However, in the method of producing a multicolor pattern tile by this printing method, there is a limit in the thickness of the pattern portion, and the abrasion resistance due to use is small. On the other hand, if the pattern portion is thickened, the boundary line of the pattern may become unclear, and further, the work of filling the tile main body powder in the press molding portion may take a long time, which may reduce the mass productivity.

In view of the above, the present invention provides a multicolor pattern tile which can be mass-produced at low cost by clarifying the boundary line of the pattern portion and ensuring a sufficient thickness to improve abrasion resistance. It is an object to provide an apparatus and a manufacturing method.

During the filling of the first to third colored powder particles 111a to 111c, the filling spaces 23 to 23i other than the filling spaces 23a to 23i to be filled are the guide frames 41, 51, 61.
Since it is completely shielded by the bottom portion of the colored powder particles 111a to 111c, the unintended filling spaces 23a to 23i are filled with other colored powder particles 111a to 111c.
Is not mixed.

First to third colored powder particles 111a to 11
The patterned frame 20 filled with 1c is the next time (4
By the intermittent movement of the (second time), it moves from the third powdery or granular material filling device 60 to immediately below the fourth powdery or granular material filling device 70. However, in the present embodiment, since only three colors are used as the colored powder particles and the fourth color is not used, the filling operation is not performed in the fourth powder or granular material filling device 70, and the patterned frame 20 is on standby. Held in a state.

Next, the patterned frame 20 is attached to the carrier plate 13.
By the next (fifth) intermittent movement of, the fourth powdery or granular material filling device 70 is moved to immediately below the fifth powdery or granular material filling device 80.
At this time, the guide frame 81 is in a state in which the filling box 85 is already mounted. Then, in the backing powder and granular material filling step, the guide frame 81 of the fifth powder and granular material filling device 80 is moved down from the standby position to the mounting position in FIG. The control piece 25 of 20 is fitted tightly and attached. Then
The opening of the filling portion 83 of the guide frame 81 is the first of the patterned frame 20.
Through, they are aligned with and face the ninth filling spaces 23a to 23i. After that, the filling box 85 storing the backing powder particles 112 is reciprocally slid from the hopper 87 between the left end position (solid line position) and the right end position (two-dot chain line position in the figure) in FIG. Then, the backing granules 112 from the filling box 85 fill the first to ninth filling spaces 23a to 23i through the openings of the filling portion 83, and the first to third colored powder granules 111a to 111c.
It drops down and is filled in the filling space 83a in the filling portion 83. After this, unlike the first to third colored powder and granular material filling steps, the guide frame 81 of the fifth powdery or granular material filling device 80 is attached to the patterned frame, and the filling box 85 is attached to the guide frame 81. With the guide frame 81 and the filling box 85 placed on the patterned frame 20,
At the same time, it is transported along the transport path. This holds the backing granules 112 in the filling portion 83 of the guide frame 81,
This is to prevent the backing powder particles 112 from overflowing to the outside. As a result, the filling of the patterned frame with the first to third colored powder particles 111a to 111c and the backing powder particle 112 is completed. Note that the filling box 85 is left on the guide frame 81 because the backing powder particles 112 remaining in the filling box 85 are
This is because by removing the filling box 85, it is possible to prevent an excessive inflow into the filling portion 83 of the guide frame 81. Therefore, one backing powder granule 112 is filled in the filling box 83,
The filling box 83 may be moved upward and removed from the guide frame 81 if an excessive amount is prevented from flowing in.

The thickness of the first to third colored powder particles 111a to 111c, which form the pattern portion 101, is equal to the thickness of the backing portion 102.
The height of the filling spaces 23a to 23i of the patterned frame 20 and the height of the filling portion 83 of the guide frame 81 are set so as to be sufficiently larger than the thickness of the backing powder 112. For example, the filling spaces 23a to 23a so that their ratio is about 2: 1.
The height of i and the filling portion 83 is also set to about 2: 1. In addition,
The filling amount of the backing granules 112 into the filling portion 83 of the guide frame 81 is determined by the plane dimension of the filling portion 112 and the outer frame 21 of the patterned frame 20.
In order to make it slightly smaller than the plane size of the above, the amount may be slightly larger than about one third of the total wall thickness.

Next, the patterned frame 20 is moved to the fifth powdery or granular material filling device 80 by the next (seventh) intermittent movement of the carrier plate 13.
To the patterned frame holding position P, and waits at the patterned frame holding position P until the next intermittent movement of the transport plate 13.

Next, the patterned frame 20 is moved from the patterned frame holding position P to just below the press forming means 90 by the next (8th) intermittent movement of the transport plate. Then, FIG. 9
As shown in FIG. 5, the mounting hole 13a of the carrier plate 13 and the through hole 11a of the base 11 are aligned and communicate with each other, and the internal space of the outer frame 21 of the patterned frame 20 in the mounting hole 13a is the pressing surface of the lower mold 92. 9
It faces 2a. At this time, the lower die 92 is pressed against the press surface 92.
It is located at an initial position where the upper surface as a is flush with the upper surface of the base 11, and does not contact or interfere with the lower surface of the transport plate 13. As a result, the patterned frame 20 becomes the partition plate 2
It is placed on the pressing surface 92a of the lower mold 92 via 2a to 22h, and the first to ninth filling spaces 23a to 23i.
First to third colored powder particles 111a to 111 filled in
c and the backing powder granules 1 filled in the filling portion 83 of the guide frame 81
12 is supported on the lower mold 92.

And, these colored powder particles 113a-1
13c and the backing powder 112 are press-molded by the press-molding means in the next press-molding step, and
The tile molded body 100 shown in FIG. More specifically, FIG.
As shown in 0, first, the upper die 91 is moved downward from the initial position to the first lowering position, and the backing granules 112 in the filling portion 83 supported by the lower die 92 via the patterned frame 20 The pressing surface 91a of the upper mold 91 is brought into contact with the upper surface, and the first to third colored powder particles 111a to 111c and the backing powder particles 112 are moved by the upper mold 91, the lower mold 92, the outer frame 21, and the filling portion 83. Keep it in the enclosed space that is formed to prevent it from overflowing.
Next, the upper mold 91 and the lower mold 92 are synchronously moved downward,
As shown in, the upper die 91 is moved from the first lowered position to the second lowered position, and the lower die 92 is placed from the initial position to the first lowered position. As a result, the patterned frame 20 descends, the lower end of the outer frame 21 comes into contact with the upper surface of the mold main body 94 at the lower surface position of the base 11, and the receiving plate 21 of the patterned frame 20.
Contacts the upper surface of the carrier plate 13. At this time, the patterned frame 2
The movement control of the upper mold 91 and the lower mold 92 is performed so that the lower end of 0 and the press surface 92a of the lower mold 92 are not separated from each other even a little.

Thereafter, as shown in FIG. 12, the upper die 91 is once moved to the initial position, and then the patterned frame 20 and the guide frame 81 are moved upward by a robot hand or the like as shown in FIG. And remove it from the mounting hole 13a of the carrier plate 13. At this time, in synchronization with the upward removal of the patterned frame 20 and the guide frame 81, the lower mold 92 is slowly moved down from the first lowered position to the second lowered position, and the first to third colorings are performed. The powder particles 111a to 111c and the backing powder particles 112 are the transport plate 1.
Make sure that the top surface of 3 does not overflow outside. This allows
The upper surface of the backing powder 112 is flush with the upper surface of the transport plate 13, and the first to third colored powders 111a to 111c and the backing powder 112 are the pressing surface 92a of the lower die 92 and the transport plate. It is stably held in a space surrounded by the mounting hole 13a of the base 13 and the through hole 11a of the base 11. At this time, although the upper surface of the backing powder 112 after removing the patterned frame 20 may be slightly disturbed, the colored powders 111a to 111a are formed.
The boundary line between c is not disturbed. The removed patterned frame 20, the guide frame 81, and the filling box 85 are reused in the patterned frame mounting means 30 and the fifth powdery or granular material filling means 80 in the subsequent steps.

Then, as shown in FIG. 14, the upper die 91 is moved downward again so that its pressing surface 91a becomes flush with the upper surface of the carrier plate 13 and contacts the upper surface of the backing powder 112 on the lower die 92. The third descending position is in contact. After that, the backing powder 112 and each colored powder 111 are provided between the upper mold 91 and the lower mold 92.
a to 111c are sandwiched so that the backing powder 112 and the colored powders 111a to 111c do not overflow from the upper surface of the carrier plate 13 to the outside, as shown in FIG. The mold 92 is synchronously moved down to the press position and pressed between the upper mold 91 and the lower mold 92 with a pressing pressure of about 500 kg / cm ² . After that, in the product take-out step, as shown in FIG. 16, the upper mold 91 is moved upward to return to the initial position, and the lower mold 92 is moved upward to the projecting position to transfer the pressed tile molded body 100 to the conveying plate. It is exposed a predetermined distance above the upper surface of 13 and is taken out to the outside by a tile taking-out means (not shown). The taken-out tile molded body 100 is then fired in a known firing process to form a plate-shaped multicolor pattern tile having a striped pattern of three colors on the front surface and a backing material on the back surface. The firing of the tile molded body 100 may be performed by applying glaze to the surface of the tile molded body 100 that has been unglazed to form a glaze tile, or may be a non-glaze tile that has been unglazed.

The molding operation of the tile molded body 100 in each patterned frame 20 mounted in each mounting hole 13a of the carrier plate 13 is as described above. However, as a whole of the apparatus for manufacturing a multicolor pattern tile of this embodiment, , Each of the eight patterned frames 20 mounted in the total eight mounting holes 13a sequentially perform each process from the patterned frame mounting process to the product unloading process in accordance with each intermittent movement operation of the carrier plate 13. Since the tile molded body 100 is continuously formed, the tile molded body 100 is continuously formed by the patterned frames 20 after the tile molded body 100 is molded by the first press molding process.
Molding operation is performed. That is, for each press molding operation,
The carrying plate 13 is intermittently moved by 45 degrees in the direction indicated by the arrow in FIG. 1, and each step of filling the patterned frame 20 with the colored powder particles is performed. In addition, the intermittent movement cycle of the patterned frame 20 by the transport plate 13 is determined by the patterned frame 20 in the press molding means.
From the removal operation time of (1) to the total time of the press molding time of the colored powder particles 111a to 111c and the backing powder particles 112 and the take-out time of the tile molded object 100, which is determined depending on the time.

Here, the colored powder particles 111a-
The adjustment of 111c is performed by granulating a predetermined slurry with a known granulation method such as a spray dryer method or a filter pressing method to a predetermined water content with a predetermined particle diameter. For example, JP-A-6-2
According to the method described in Japanese Patent No. 54821, feldspar, porcelain clay, kaolin, clay, and the like are used as raw materials, and the same materials as ordinary tiles are used as raw materials. To this, pigments for coloring, organic binders, and water are added, and tron mill is used. Then, the mixture is pulverized, slurried, and then granulated to a predetermined water content by a spray dryer or the like to obtain a colored powder or granule having a desired color. In addition, the colored powder particles 111a to
The larger the size of the tile to be manufactured, the larger the particle size of 111c is,
It may be large, and the maximum value may be about 1 mesh to about 25 mm. In this case, it is preferable to simultaneously fill powders having a smaller particle diameter to prevent insufficient filling and to increase the water content to make plastic deformation easier.
In particular, when molding a tile having a spotted pattern, it is preferable to use a tile having a large particle size. In addition, the colored powder particles 11
The minimum particle size of 1a-111c can be about 250 mesh. When the particle size of the colored powder particles 111a to 111c is smaller than 250 mesh, the fluidity of the colored powder particles 111a to 111c is lowered, and voids may occur in the corners of the molding space after the colored powder particles 111a to 111c are filled. Further, backing powder granules 1
12 can be manufactured in the same manner as the colored powder particles 111a to 111c.

In the adjustment of the colored powder particles 111a to 111c and the backing powder particles 112, the tile material and the pigment of a predetermined color are wet pulverized by a wet tron mill and mixed, and then,
It is more preferable to carry out spray drying with a spray dryer and granulate to about 30-100 μm. This is because the powder particles 111a to 111c and 112 in this particle size range are rich in fluidity and are filled in the filling space 23a of the patterned frame 20 which is a molding space.
This is because the inside of 23i easily and smoothly flows to every corner and fills the corner portion completely without any gap. In addition, in the present embodiment, for example, blue is selected as the first colored powder or granule 111a, green is selected as the second colored powder or granule 111b, and white is selected as the third colored powder or granule 111c. Further, the backing powder particles 112 are used for the purpose of adhering and strengthening the boundary line between the patterns formed by the colored powder particles 111a to 111c, and are not related to the design, so that the first to third parts are used. The first to third colored powder particles 1 so as not to protrude from the colored powder particles 111a to 111c to the outside.
The plane size is slightly smaller than 11a to 111c. Therefore, the filling portion 83 of the guide frame 81 of the fifth powdery or granular material filling device 80
The plane size of is set to a value slightly smaller than the plane size of the internal space of the outer frame 21 of the patterned frame 20.

As described above, the multicolor pattern tile manufacturing apparatus according to the above-described embodiment has a plurality of colored powder particles 111a.
A tile molded body 10 having a multicolor pattern formed by press molding 111c
In the apparatus for producing a multicolored pattern tile, which is obtained by firing the tile molded body 100 as 0, it is intermittently moved at a predetermined interval along the circumferential direction, which is a predetermined transport path, on the annular plate-shaped base 11. An annular plate-shaped carrier plate 13 as a carrier means, an outer frame 21 as an outer shape providing member that forms a space corresponding to the outer shape of the tile molded body 100, and an inner space of the outer frame 21 are adjacent to each other in the plane direction. Then, it has partition plates 22a to 22h as partition members which form a plurality of filling spaces 23a to 23i extending in the thickness direction of the tile molded body 100, and a plurality of the partition plates 22a to 22h are arranged along the transport path of the transport plate 13 at the predetermined intervals. A patterned frame 20 as the pattern forming means to be arranged, a patterned frame mounting means 30 for mounting the patterned frame 20 on the carrier plate 13 at predetermined intervals, and a different color along the carrier path of the carrier plate 13. Granules 111a The 111c arranged at the predetermined intervals,
Corresponding to the stopping operation of the carrier plate 13, the patterned frame 2
The colored powder particles 1 of a predetermined color in each of the filling spaces 23a to 23i
First as a filling means for sequentially filling 11a to 111c
Thru | or the 4th powder-and-particles filling device 40, 50, 60, 70, and the predetermined | prescribed color which was arrange | positioned in the conveyance path downstream from the said 4th powder-and-particles filling device 70, and was filled up in the said filling space 23a-23i. A fifth powdery or granular material filling device 80 for filling the backing powdery or granular material 112 on the powdery or granular materials 111a to 111c, and a filling end position of the transporting path of the transporting plate 13 are arranged at the filling space 23a.
To 23i filled with colored powder particles 111a to 111c and backing powder particles 112 while maintaining the outer shapes of the patterned frame 20.
And the colored powder particles 111a to 111c and the backing powder particles 112 are press-molded and the tile molded body 100 is removed.
And a press forming unit 90.

Therefore, in the multicolor pattern tile manufacturing apparatus according to the above-described embodiment, the patterned frames 20 are mounted on the carrier plate 13 at predetermined intervals by the patterned frame mounting means 30.
When the patterned frame 20 is intermittently moved along the transport path at predetermined intervals by means of the above, the first to the fourth frames are moved every time the transport plate 13 stops moving.
The colored powder particles 111a to 111c of different colors are sequentially filled in the corresponding filling spaces 23a to 23i of each patterned frame 20 by the filling means 40, 50, 60 and 70. Then, in the press molding means 90, the colored powder particles 111a
~ 111c and the backing powder 112 are maintained, the patterned frame 20 is removed from the carrier plate 13, and then the colored powders 111a to 111c and the backing powder 112 are integrally press-molded. , Multicolored patterns 101a-101 on the surface
A tile molded body 100 having a predetermined shape having a pattern portion 101 made of c and a backing portion 102 on the back surface is obtained.

As described above, since the tile molded body 100 is molded every time each of the patterned frames 20 reaches the press molding means 90, the tile molded body 100 is continuously obtained by the intermittent movement of the carrier plate 13. be able to. Therefore, other steps are also progressed and completed for each total time of the removal operation time of the patterned frame 20 in the press forming step and the press operation time continuous thereto. That is, since the productivity of the tile molded body 100 depends only on the operation required time in the press molding unit 90, the overall productivity is improved and the operation of the apparatus is facilitated. Further, by setting the operation time to a desired value, it is possible to easily make a mass production plan. Then, the conveying means, the pattern forming means, the filling means,
Since various means such as the pattern frame mounting means 30 and the press molding means 90 can be variously automated, the whole can be fully automated or semi-automated to further improve the productivity. Furthermore, since the pattern of each color is continuous in the thickness direction of the multi-colored pattern tile obtained by firing the tile molded body 100, its designability is maintained even if the surface (designed surface) is worn due to long-term use. Is not lost, and the boundary line between each color pattern can be maintained in a clear state. Particularly, as in the above embodiment, for example, if the thickness of the backing portion 102 is set to about 1/3 of the thickness of the entire tile and the thickness of the pattern portion 101 is set to about 2/3, the pattern portion Since 101 substantially withstands abrasion of its thickness and exhibits the same pattern, its designability can be maintained semipermanently. In addition, it is preferable that the thickness ratio of these is such that the thickness of the pattern portion 101 is about half or more of the entire thickness in consideration of long-term use. Further, the setting of the color pattern is independent of the press-molding means 90, and as long as the frame 20 with the pattern can be removed by the press-molding means 90, the frame 20 with the pattern can be set.
And the first to fourth powder / granular material fillers 40, 50, 60, 7
Since it can be arbitrarily performed by changing the specification of 0, the number, shape, type, etc. of the patterns can be appropriately changed.

In addition, in the above embodiment, the through hole 1 through which the lower mold 92 can be inserted is inserted into the base 11 portion facing the lower mold 92.
1a is provided so as to be aligned with the mounting hole 13a of the carrier plate 13, and by the mounting hole 13a and the through hole 11a,
The first to third colored powder particles 111a to 111c and the backing powder particle 11 after the patterned frame 20 and the guide frame 81 are removed.
Since 2 is held in the shape, it is not necessary to provide a special member for holding the shape, the configuration of the entire apparatus is simplified, and the cost can be reduced. Further, the filling space 23a for performing patterning of a predetermined shape only by mounting the outer frame 21 of the patterned frame 20 in the mounting hole 13a of the transport plate 13.
Since ~ 23i are formed in a predetermined number at a predetermined position on the carrier plate,
It is only necessary to change the configuration of the patterned frame 20 according to the desired pattern, and the overall cost can be reduced.

Further, the first to third colored powder particles 11 in the first to ninth filling spaces 23a to 23i of the patterned frame 20.
In 1a to 111c, the lower surface that finally becomes the design surface of the multicolor pattern tile slides on the upper surface of the base 11.
Since the transport plate 13 slides on the base 11 in a close contact state, the colored powder particles 111a to 111c are formed into the patterned frame 20 by appropriately selecting the particle size within the range described in the above embodiment. There is no leakage beyond the outer frame 21 between the carrier plate 13 and the base 11 or beyond the partition plates 22a to 22h into the adjacent filling spaces 23a to 23i, and the boundaries between the patterns are substantially unclear. It never becomes. On the contrary, base 1
Since the density of each of the colored powder particles 111a to 111c in each of the filling spaces 23a to 23i increases while sliding 1, the subsequent press molding can be performed more smoothly, and molding unevenness and the like can be prevented more effectively. can do.

In the method for manufacturing a multicolored pattern tile according to the above-mentioned embodiment, a plurality of colored powder particles of different colors are press-molded to form a multicolored pattern tile molded body 100, and the tile molded body 100 is fired. In the method for manufacturing a multicolor pattern tile, the outer frame 21 as an outer shape providing member that forms a space corresponding to the outer shape of the tile molded body 100 and the inner space of the outer frame 21 are partitioned adjacent to each other in the plane direction, The patterned frame 20 as a pattern forming unit having partition plates 22a to 22h as partition members that form a plurality of filling spaces 23a to 23i extending in the thickness direction of the tile molded body 100, and a transfer plate 13 as a transfer unit. A plurality of transfer steps are arranged along a predetermined transfer path at predetermined intervals, and a transfer step of intermittently moving the transfer plate 13 at the predetermined intervals along the transfer path; Colored powder or granular material of color 111a~111c
And the backing powder particles 112 are arranged at the predetermined intervals, and the colored powder particles 111a of a predetermined color are filled in the filling spaces 23a to 23i of the patterned frame 20 in accordance with the stop operation of the transport plate 13.
~ 111c are sequentially filled and colored powder particles 111a
To 111c, a filling step of filling the backing powder particles 112, the colored powder particles 111a to 111c, and the backing powder particles 11
After removing the patterned frame 20 while maintaining the outer shape of 2,
The colored powder particles 111a to 111a are formed by the press molding unit 90 arranged near the end position of the transfer path of the transfer plate 13.
and a press forming step of press forming c.

Therefore, in the manufacturing method of the multicolor pattern tile of the above-described embodiment, each frame 20 with a pattern is formed in the carrying step.
Are attached to the transport plate 13 at predetermined intervals, and the patterned frame 20 is intermittently moved by the transport plate 13 at predetermined intervals along the transport path, and in the filling step, every time the transport plate 13 stops moving, the first to fourth The colored powder particles 111a to 111c of different colors are sequentially filled in the corresponding filling spaces 23a to 23i of each patterned frame 20 by the filling means 40, 50, 60 and 70. Then, in the press molding step, the colored powder particles 11

Therefore, when the pattern forming means is mounted on the conveying means at a predetermined interval in the carrying step and the pattern forming means is intermittently moved along the carrying path by the carrying means at a predetermined interval, the movement of the carrying means is stopped in the filling step. Each time, the filling means successively fills the colored powder particles of a predetermined color into the corresponding filling space of each pattern forming means. Then, in the press molding step, while maintaining the outer shape of the colored powder or granular material, after each pattern forming means is removed from the conveying means, the colored powder or granular material is integrally press molded to have a multicolored pattern on the surface. A tile molded body having a predetermined shape is obtained.

As described above, since the tile formed body is formed every time each pattern forming means reaches the press forming means, the tile formed body can be continuously obtained by the intermittent movement of the conveying means. Therefore, other steps are also progressed and completed for each total time of the removing operation time of the partition member of the pattern forming means in the press forming operation and the press operation time continuous thereto. That is, since the productivity of the tile molded body depends only on the operation required time in the press molding means, the overall productivity is improved and the operation of the apparatus is facilitated. Further, by setting the operation time to a desired value, it is possible to easily make a mass production plan. Since each of the conveying means, the pattern forming means, the filling means, and the press molding means can be variously automated, the whole can be fully automated or semi-automated to further improve the productivity. Furthermore, since the pattern of each color is continuous in the thickness direction of the multi-colored pattern tile obtained by firing the tile molded body, the designability of the tile is improved even when the surface (designed surface) is worn due to long-term use. It is not lost, and the boundary line between each color pattern can be maintained in a clear state.
