Description

Detailed Description of the Invention "Field of Industrial Application" The present invention is capable of producing not only basic patterns such as irregularities and waves formed during extrusion molding, but also by drawing additional patterns superimposed on the basic patterns. , relates to a tile with various composite patterns on its surface and a method for manufacturing the same.

``Prior Art'' The functions of tiles include, in addition to the function of protecting buildings by being attached to them, they also have a decorative function by means of patterns attached to their surfaces. In recent years, as consumer demands have diversified, more and more emphasis has been placed on decorative functions among the above functions. especially,
In order to harmonize the surface pattern of tiles with the construction environment, there is an increasing demand for giving uniqueness to buildings as signs through tile walls. In order to meet such consumer demands, not only are tile surfaces provided with colored patterns, but also three-dimensional shapes are provided. Conventionally, in order to form the three-dimensional shape on the tile surface, when using the press molding method, the inner surface of the mold is shaped so that a three-dimensional pattern is formed on the tile surface, and when using the extrusion molding method, This has been done by making the mouth shape of the extrusion port uneven or wavy, or by pressing patterns, designs, etc. onto the surface of the extruded product using a roller having unevenness, undulations, etc. on the circumferential surface. However, with the above-mentioned conventional pattern drawing methods, the resulting pattern does not vary widely, making it difficult to meet the diverse demands of consumers.

"Means for Solving the Problems" In view of the above-mentioned problems, the present invention aims to provide a tile having a variety of three-dimensional patterns formed on its surface. In a tile manufactured by a combination of a molding method and a roller molding method, a base pattern formed by the mouth mold of an extrusion molding machine and an additional pattern formed by the roller surface are superimposed on the surface of the tile. The feature of the method for manufacturing tiles according to the present invention is that in the tile extrusion method, when an extrusion molding machine is filled with clay and the clay is extruded to obtain an extrusion molded product, the extrusion molded product is A basic pattern is formed on the surface of the extruded product by passing it through a mouth mold whose part in contact with the surface side has an uneven, wavy, etc. shape, and then the irregularities, undulations, etc. connected to the exit of the mouth mold are formed. An additional pattern is pressed onto the surface of the extruded product by overlapping the basic pattern with a roller having an appropriate shape on the circumferential surface, and then finished through processes such as cutting, drying, glazing, and firing to create a composite material. The purpose is to produce tiles with patterns.

``Example'' A tile having a composite pattern and a method for manufacturing the same according to the present invention will be described below based on the drawings. Note that each example describes an example in which a halved tile is manufactured by extrusion molding.

Figures 1a and 1b show an example of the manufacturing status of the tile of the present invention, and in Figure 1a,
Reference numeral 1 denotes an extrusion molded product, 2 a tile extrusion molding machine, and 3 a roller connected to an extrusion port of the extrusion molding machine 2 for pressing an additional pattern on the surface of the extrusion molded product. Further, FIG. 1B shows the shape of the mouth shape of the extrusion port 2a of the extrusion molding machine 2.

First, the extrusion molding machine 2 is filled with clay, which is a raw material for forming tiles, and the clay is extruded from the extrusion port 2a to obtain the extruded body 1. At this time, as shown in Figure b, the mouth shape of the extrusion port 2a has an uneven shape at the part that contacts the surface of the extrusion molded product 1, so that the surface of the extrusion molded product 1 has a continuous shape along the extrusion direction. Specifically, the uneven strips 1a and 1b are extended. The uneven strip 1
a and 1b form the basic pattern of the tile of the present invention.

Next, an additional pattern is pressed onto the surface of the extruded body 1 by means of rollers 3, 3 which are arranged in parallel at the extrusion port of the extrusion molding machine 2 at an interval slightly narrower than the thickness of the extruded body 1. In this embodiment, the rollers 3,
3 is one in which annular protrusions 3a are arranged on the circumferential surface at the same intervals as the formation intervals of the protrusions 1b, and an additional pattern can be pressed and overlapped only on the surface of the protrusions 1b of the basic pattern. This is how it was done. The surfaces of the annular protrusions 3a of the rollers 3, 3 are formed into undulating surfaces, and by appropriately changing the degree of undulation, a desired uneven pattern can be added to the surface of the ridges 1b of the basic pattern.

The extrusion molded body 1 on which the composite pattern is drawn on the surface as described above is finished into a tile through cutting, drying, glazing, firing, and other steps.

FIG. 2 shows an embodiment of another aspect of the invention. A feature of this embodiment is that protrusions 3b along the axial direction are arranged on the circumferential surfaces of the rollers 3, 3 at appropriate intervals. The rollers 3, 3 press and form recesses on the surface of the extruded body 1 as additional patterns at predetermined intervals along the extrusion direction.

In addition to the above-mentioned embodiments, the additional pattern of the tiles of the present invention may be a roller 3 having large and small annular protrusions 3c arranged at irregular intervals on the circumferential surface as shown in FIG. By using a roller 3 or the like having protrusions 3d protruding over the entire circumferential surface, an additional pattern different from that of the previous embodiment can be pressed.

Furthermore, when an uneven basic pattern is formed on the surface of the extrusion molded product, it is also possible to press the additional pattern only into the recessed portions of the basic pattern. To do this, a roller 3 is prepared in which a plurality of disks 30 having undulating shapes on the peripheral end surface are pivotally mounted on a support shaft 4 as shown in FIG. By bringing the roller 3 into contact with the surface of the extrusion molded body 1, the additional pattern can be pressed only into the concave portions 1a of the basic pattern. In addition, when attempting to press an additional pattern only on the side surface portion 1c of the protruding strip, please refer to Fig. 6a.
This is possible by bringing the roller 3, which has a plurality of disks 31 as shown in FIG.

The basic pattern of the tile according to the present invention is not limited to the above-mentioned uneven stripes. In Figure 6 a to c,
Other embodiments of the shape of the mouth shape of the extrusion port 2a of the extrusion molding machine that defines the basic pattern have been shown; By using a wavy shape as shown in FIG. 2, or a serrated shape as shown in FIG.

An example in which the present invention is applied to a halved tile has been described below, but it goes without saying that the present invention can also be applied to the production of ordinary single-piece tiles.

``Effects of the Invention'' According to the present invention, a composite pattern is drawn on the tile surface by pressing an additional pattern overlapping a basic pattern such as three-dimensional unevenness or waveform. A wide variety of changes can be obtained by selecting various combinations. Due to the nature of the manufacturing process, this composite pattern is never exactly the same, and each tile has a slightly different shape. However, although they are slightly different, the composite pattern of the proposed tile is aesthetically unified and has its own individuality. Therefore, when viewed as a whole, an exterior wall surface constructed of tiles of the present invention exhibits an excellent aesthetic appearance that combines an organic sense of continuity and a sense of dynamism. Moreover, since the tile manufacturing method of the present invention can be achieved by making slight changes to the conventional extrusion molding method, it does not increase manufacturing costs or complicate the manufacturing process.

In short, the present invention provides a tile with a composite pattern at a low cost that can meet the various demands of consumers.
