Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a spotted stone pattern tile and an apparatus for producing the same.

Conventionally, stone-grain patterned tiles with spots have been manufactured using a press molding method using a dry molding method.

In addition, wet extrusion molding can be manufactured at low cost.
Because the fine clay particles concentrate on the surface of the clay and form a layer of fine particles, it was not possible to produce tiles with a vivid speckled pattern.

Conventional products include: (a) A tile with a spotted pattern formed on the surface of the tile by colored pigments etc. melting from inside the tile.

(b) A tile whose surface has been simply peeled off, and which is scratched by rough particles that were in the cracks when the tile surface was peeled off.

(c) A tile that is coated with glaze to fill in the scratches caused by particles in the clay when the surface is removed.

etc., but none of the tiles had a stone pattern with bright speckles on the surface.

An object of the present invention is to provide a manufacturing method and a manufacturing apparatus for manufacturing beautiful speckled stone pattern tiles at a low cost, eliminating the above-mentioned drawbacks, and embodiments thereof will be described in detail with reference to the drawings. Then, as shown in FIG. 4, the tile clay 2 extruded from the conventional vacuum clay kneading machine 1 has a layer of fine clay particles formed on both sides of the surface, so colored particles 9, which will be described later, are not present on the surface. Immediately after the extrusion mold 4, a piano wire 5, for example, is used as a peeling means so that the surface layer 3 on both sides of the tile clay 2 can be automatically peeled off at the position g indicated by the two-dot chain line.
In addition to this, a pressing roller 7 is also installed to neatly press and finish the surface 6 of the tile clay 2 from which the surface layer 3 has been peeled off.

The method of the present invention [The tile for producing stone-patterned tiles with trowel spots is produced in the steps shown in Figure 3. Clay mixed with colored particles 9, for example, coarse-grained minerals such as ceramic powder, biotite powder, manganese ore powder, etc., is automatically introduced into molding clay 8 using a belt conveyor or the like.

Tile clay 2 is continuously extruded from an extrusion die 4 of a vacuum clay kneading machine 1 in a back-to-back state.

The extruded tile clay 2 is automatically separated from both surface layers 3, 3 of the tile clay 2 by a peeling means provided immediately after the extrusion mold 4, that is, two piano wires 5, 5. stripped away.

The surfaces 6, 6G of the tile clay 2 from which both side surface layer parts 3, 3 have been peeled off are pressed by a pressing finishing roller 7, and are finished neatly.

The tile clay 2 with finished surfaces 6 and 6 was produced in the Tokuko Sho 5
The extruded clay is automatically cut into a predetermined size using a well-known cutting device 10 for extruded clay as described in Japanese Patent No. 8-14284.

The tile clay 2 cut to a predetermined size is automatically placed on a rolling cart and dried and fired in a conventional manner. Tiles fired back-to-back are separated as necessary.

Next, regarding another embodiment of the present invention, the same reference numerals will be used for the same parts as in the previous embodiment, and the explanation will be omitted, and only the different parts will be described in detail. The surface layer 3 on both sides of the tile clay 2 is peeled off using a spatula II such as a board spatula or metal spatula as shown in Figure 5.
, 11, the both side surface layer parts 3, 3 may be peeled off.

In addition, as shown in FIG.
The patterning of one hole on a ceramic plate described in the above publication may be done by pressing the surface 6 of the tile clay 2 with a pressing roller that reciprocates by a predetermined angle using a sector gear mechanism or the like, as in the apparatus described in the above publication.

In addition, the suppression finishing roller 7G is a roller with an uneven pattern,
Alternatively, a roller without an uneven pattern may be used.

Further, it is not limited to the pressing finishing roller 7, and a pressing plate or the like may be used.

With the above method and configuration, the layer of fine clay particles formed on the surface of the clay extruded from the extrusion mold of the vacuum clay kneading machine is peeled off by a peeling means such as a piano wire. As a result, the colored particles mixed in the clay appear on the surface, making it possible to produce physically or mechanically beautiful and bright speckled stone pattern tiles.

Moreover, since it is an automatic molding method using an extrusion vacuum clay kneading machine, it can be mass-produced at low cost, and has extremely high economic value.

It goes without saying that the present invention is not limited to the above-mentioned embodiment G; for example, the peeling means such as piano wires may not be provided at the same location on the left and right, but one may be placed near the extrusion die of the clay kneading machine. It is also possible to use a configuration in which one set of piano wires is provided, and the other is placed at a slightly distant position, or multiple piano wires, etc. can be peeled off in multiple stages with a trowel, or a pair of left and right piano wires can be peeled off independently. It is also possible to adjust the stripping depth to the desired depth, and it is also possible to provide pressure rollers at multiple locations instead of just one pair. It is something.

As described above, the present invention can provide a method for manufacturing beautiful spotted stone pattern tiles at low cost and an apparatus for manufacturing the same.
