DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry method for manufacturing tiles.

[0002]

2. Description of the Related Art Some of the tiles currently produced have a roughened surface for the purpose of giving a natural texture. These tiles have characteristics such as being able to give an old-fashioned and solid feeling to a building, and the demand for them is increasing in recent years.
Thus, conventionally, first, a tile having a thickness approximately twice the size to be obtained was press-molded, and the molded product was divided into halves to manufacture the tile as described above.

[0003]

As described above, when one thick tile is divided into two, in most cases, the volume is offset to one side and the other is poor. Therefore, there is a problem that only the one with a volume is shipped as a product and the other one is discarded, so that there is much waste, and moreover, the labor for breaking the tile is added, resulting in high cost. It was In addition, since the shape of the tile is not known until it is broken, it is a half-manufactured unstable manufacturing method, so there was a fatal problem that a product of constant quality could not be stably mass-produced. . In addition, even if an attempt is made to form a tile as described above by forming unevenness of a natural shape on the molding surface of the mold, it is not possible to wipe away the artificial atmosphere with the unevenness pressed by the press, and the tile is Since they all have the same uniform shape, they end up being half-finished products that do not produce a natural feel.

[0004]

In order to solve the above problems, the present invention provides a granular kneaded clay for tiles and a roughened surface which is a powder or particles of a material which is burned down at a temperature equal to or lower than the firing temperature of the tiles. Using a material and a mold that press-molds a material with a combination of recesses and protrusions, if the bottom of the recess of the mold corresponds to the surface of the tile, use a roughened material, or of the recess of the mold. When the bottom surface corresponds to the back surface of the tile, the first step of putting the tile kneaded material into the concave portion of the mold, and the tile kneaded material when there is a roughened material in the concave portion, and also in the concave portion. If there is a kneaded clay for tiles, a second step of placing the roughened material, a third step of pressing the kneaded clay for tiles and the roughened material with the convex portion of the mold to press them together, and The 4th step of burning the press-molded product of the clay for tiles and the surface-roughened material compacted in three steps to burn off the surface-roughened material , There is provided a dry method for producing a tile made of.

[0005]

[Function] In the press-formed product that has been pressed and solidified through the first to third steps, the roughened material is entangled with the surface of the clay for tiles.
Are connected. Then, when the press-formed product is fired in the fourth step, the roughened material is burned out. Therefore, the surface of the baked tile has a shape in which the portion where the roughened material was present is missing. Since the roughened material is powder or granular,
The tile surface of the burned traces is roughened by the traces of the roughened material. In addition, since the surface-roughened material is powdery or granular and does not have a uniform shape, the finished tiles have different surface shapes.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. 1 (a) to 1 (c) are views showing a dry manufacturing process of a tile, FIG. 2 is a perspective view of a press-formed product, and FIG. 3 is a perspective view of a tile.

The dry manufacturing method of tiles of the present invention uses a tile clay 1, a roughened material 2, and a die 3 for press molding. As the clay for tile 1, the granular powder used in the conventional dry manufacturing method of tile is used as it is. The roughening material 2 is made of a material that is burned down at a temperature of about 1250 ° C. or lower, which is the baking temperature of tiles, such as synthetic resin, grains, and plant leaves, and is processed into powder or particles. The mold 3 is one in which a material is press-molded by a combination of the concave portion 3a and the convex portion 3b, and in this embodiment, the bottom surface 4 of the concave portion 3a corresponds to the surface of the tile 5. The bottom surface 4 of the recess 3a is provided with irregular asperities in order to make the surface of the tile 5 uneven to some extent.

Next, a dry manufacturing method of tiles will be described. First, as shown in FIG. 1A, the roughened material 2 is put into the recess 3 a of the mold 3. The surface-roughened material 2 is used for the purpose of roughening the surface of the tile 5 to have a natural texture, and is inserted so that it can be slightly offset (first step). Next, as shown in FIG. 1 (b), a granular tile clay 1 is placed on the roughened material 2 (second step). Here, if necessary, a pigment for ceramics (if it is too strong alone, it is appropriately mixed with soil) may be interposed between the kneaded clay 1 for tile and the roughened material 2.

Next, as shown in FIG. 1 (c), the convex portion 3b of the mold 3 is lowered to press the tile clay 1 and the roughened material 2 together. As a result, the clay for tiles 1 and the surface-roughened material 2 are pressed together to form a tile-shaped press-formed product 6 as shown in FIG. Next, the press-formed product 6 is fired at about 1250 ° C. to harden the clay for tiles 1.
Since the roughened material 2 is completely burned down by this firing,
The finished tile 5 has a form in which the portion where the roughened material 2 was present is missing as shown in FIG. In addition, rough surface processing material 2
At the boundary surface between the clay for tile 1 and the clay for tile 1, the roughened material 2 and the clay for tile 1 are intertwined with each other.
The surface of the tile 5 after being burned is rough and rough.
The shape of the surface of the tile 5 can be freely changed by appropriately adjusting the degree of insertion of the roughened material 2.

4A to 4C, the bottom surface 4 of the concave portion 3a of the mold 3 corresponds to the back surface of the tile 5, and the end surface of the convex portion 3b of the mold 3 corresponds to the front surface of the tile 5. FIG. In this embodiment, as shown in FIG. 4 (a), the clay 3 for tile is put in the concave portion 3a in the first step, and as shown in FIG. 4 (b), the clay for tile 1 is roughened in the second step. The processed material 2 is placed, and as shown in FIG. 4C, the tile kneaded clay 1 and the rough surface processed material 2 are integrally press-molded. The press-formed product thus obtained is the same as the press-formed product 6 shown in FIG. 2, and if it is fired in the fourth step, the tile 5 having a rough surface is formed.

[0011]

INDUSTRIAL APPLICABILITY As described above, according to the present invention, the surface-roughened material is superposed on the surface of the kneaded clay for tile and both are integrally press-molded,
By burning away the surface-roughened material during firing, it is possible to easily manufacture a tile whose surface has a rough texture. Then, a dry production method of the present invention, no waste compared with the conventional method has been divided solid meta tiles, Moreover, low cost because not applied also troublesome, and, stably constant quality tile It has excellent effects such as mass production.
