Abstract

PURPOSE:To obtain a thin tile which can be adhered with organic adhesive by continuously extrusion molding hybrid clay from a kneading machine to a thick rectangular rough material, reducing it to an extremely thin state by means such as rolling, etc., punching it and cutting it. CONSTITUTION:Hybrid clay C is continuously extrusion molded from a kneading machine 2 to a rectangular state having a thickness of about 10-15mm. This rough material Wa is gradually reduced in thickness by a plurality of rolling rollers 4a, 4a, 4b, ... finally to 1/2-1/5 of an initial thickness. Incidentally, the rough material Wa may be pressed or cut by a cutter to the extremely thin state. It is fed to a molding machine 5, punched, cut, etc., to a molded form Wb, and then baked. Tiles obtained in this manner are coated on rear surfaces with organic adhesive, and can be adhered directly to a wall surface.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing thin tiles by wet molding, which makes it possible to produce tiles having a thickness of 1/2 to 1/5 of conventional ones by so-called wet clay. is there.

[0002]

2. Description of the Related Art Conventionally, in wet molding of tiles, when clay clay is extruded by a kneader equipped with a mouthpiece at its tip, rough land having a cross-sectional shape corresponding to the shape of the mouthpiece is continuously formed, and the rough land is appropriately lengthened. Although it was cut into pieces and fired to form tiles, in the case of manufacturing a thin tile having a thickness of about 3 mm in this method, the area of the die attached to the tip of the kneading machine is extremely small, and the clay from the die is coarse clay. Since the pressure of pushing out becomes large, and as a result, the clay extruded from the die has a large tendency to be curled, it is extremely difficult to form a wasteland into a flat plate shape, and it has a drawback of poor productivity, Therefore, the thickness of the above method is limited to about 10 mm to 15 mm.

[0003]

The present invention realizes mass production by facilitating the production of thin tiles by wet molding with coarse clay, and makes it possible to easily apply them with an organic adhesive. It is intended to provide a method for manufacturing a thin tile by wet molding.

[0004]

SUMMARY OF THE INVENTION The present invention is based on the above-mentioned prior art, and in view of the problem that it is difficult to produce thin tiles by wet molding with coarse clay, the wasteland extruded by a kneading machine has a thickness of about 10 mm to 15 mm. And, such rough land is rolled, crushed, and ground to have a thickness of about 1/2 to 1/5, and
By punching and cutting such a rough land and shaping it into an appropriate shape, a thin tile is produced by wet molding so that the above drawbacks cannot be solved.

[0005]

According to the present invention, a thin and lightweight material which can be attached with an organic adhesive by wet molding in which a thick wasteland made of coarse clay is rolled, crushed or ground to an ultrathin state and then punched and cut. Produce tiles.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is a main body of a thin tile forming apparatus, and the main body 1 kneads coarse clay C and extrudes it as a long plate-shaped waste land Wa. The kneading machine 2, the roller conveyor 3 which is continuously provided on the work line of the kneading machine 2, the rolling rollers 4, 4a ... Which are arranged at predetermined positions of the roller conveyor 3 at predetermined intervals, and the end side of the roller conveyor 3. The waste land Wa into a molded product Wb of an appropriate shape.
It is composed of a molding machine 5 for punching and cutting.

Each of the rolling rollers 4, 4a ... Is formed by vertically arranging rollers 6 and 6a which rotate in opposite directions, and the rollers 6, 6a are made of metal, fine ceramics, synthetic resin, wood or the like. The roller 6 in each rolling roller 4, 4a ...
The distance between the rollers 6a becomes narrower toward the end side of the roller conveyor 3, and the distance between the rollers 6 and 6a in the rolling rollers 4, 4a on the final end side is about 1/2 to 1/5 of the thickness of the waste land Wa. Is set to.

In the above apparatus, the means for making the rough ground Wa extremely thin is the rolling rollers 4, 4a ..., For example, the rough ground Wa is crushed by a pressing machine (not shown), or a blade having a horizontal cutting edge. The surface of the rough Wa may be abraded by (not shown).

Explaining the method of forming the thin tile, first, the clay C is put into the clay kneader 2 and kneaded, and the clay C is 10 m thick from the tip of the clay kneader 2.
Continuously extruding a rough land Wa into a long plate shape of about m to 15 mm,
The waste land Wa is conveyed forward by the roller conveyor 3, and when the tip end of the waste land Wa reaches the first rolling roller 4, the waste land Wa is sandwiched between the rollers 6 and 6a, and the thickness is uniformly reduced. Further, the thickness gradually decreases through the second and subsequent rolling rollers 4a, 4b, ...
It consists of 1/5 of the wasteland Wa.

Further, as another means, the rough land Wa is crushed by a pressing machine (not shown), or the surface of the rough land Wa is scraped off by a blade (not shown) to halve the initial thickness.
Approximately ⅕ of extremely thin waste land Wa.

Next, the ultrathin waste Wa that has been rolled, crushed, and abraded by the above-mentioned method is sent to the molding machine 5 to form a molded product Wb having an appropriate shape by means of punching, cutting, etc. Product Wb
Is transferred to the subsequent firing step to form a thin tile W, and the cut end portion D of the molded product Wb is reintroduced into the kneading machine 2 by an appropriate means.

The thin tile W thus manufactured is coated with the organic adhesive A on the back surface thereof and directly attached to the wall surface B.

[0013]

INDUSTRIAL APPLICABILITY In short, according to the present invention, the coarse clay C is continuously extruded from the clay kneading machine 2 into a thick plate-like rough land Wa, and the rough land Wa is ultrathin by appropriate means such as rolling, crushing and shaving. In addition, since the rough land Wa is punched and cut into an appropriate shape by the molding machine 5, the thin tile W by wet molding, which is difficult by the conventional molding method, can be easily and continuously manufactured. Mass production of such thin tiles W can be achieved.

Since the thin tile W is lightweight and can be attached to the wall surface B with the organic adhesive A without peeling off, the tiling operation can be easily performed, and the tile wall surface constructed by such an operation is also possible. In the conventional thick and heavy tile, the burden on the wall surface of the lower layer is large, but the lightweight thin tile W manufactured according to the present invention can significantly reduce the burden on the wall surface B, and paper, cloth, etc. If the thin tiles W are releasably arrayed and adhered to a sheet material such as the above, several tiles can be attached at one time, so that the tile work can be further facilitated, which is a great practical effect. .
