DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention is applicable to the production of unit tiles for use in tile retrofitting methods using a plurality of tiles with directional surface patterns. The present invention relates to a novel unit tile manufacturing method that allows connecting sheets to be attached without making mistakes.

``Prior Art'' A unit tile is a group of tiles that are made up of a plurality of aligned tiles with a connecting paper pasted on the surface pattern collection surface, and are mainly manufactured for use in mosaic tiles, interior tiles, etc. ing.

"Problems to be Solved by the Invention" In the unit tile 4 using tiles 3 whose surface pattern 3a is directional, for example, the fifth
As shown by the white arrows in the figure, one or sometimes several tiles 3 within the unit were sometimes pasted onto the connecting paper 1 in a direction different from the predetermined direction. . Since the bonding paper 1 is pasted while observing the surface pattern 3a of the tiles 3, it is difficult to think of the above-mentioned arrangement error of the tiles 3 from a general standpoint. However, the current situation is that a considerable proportion of the manufactured unit tiles 4 contain such tiles.

By the way, since the unit tile 4 is made by pasting the connecting paper 1 so as to cover the surface pattern 3a of the tile 3, the above-mentioned arrangement error of the tiles 3 is caused by the wall surface of the building frame, the floor surface, etc. (not shown). omission)
It is discovered only after the unit tile 4 is pasted on and the connecting paper 1 is peeled off after it has hardened.
Therefore, the incorrectly arranged tiles 3 must be removed from the wall or floor of the building structure and reattached, resulting in a great loss in terms of labor, time, cost, and other aspects. Furthermore, the types of tiles 3 to be formed into units are rarely stocked in units at manufacturing plants, and it takes a great deal of effort and time to get them to the construction company.

The above-mentioned arrangement of tiles is caused by the fact that a large number of surface patterns of the tiles gather together, creating a visual illusion for the operator who attaches the connecting paper. In order to prevent such accidents from occurring, considering the case where a mechanical device is used to align the tile surface patterns in accordance with their direction, it is necessary to recognize and distinguish the pattern, and to be able to apply it to other types of patterns. Many problems remain, and there is little possibility of its realization. Therefore, the next possibility is to adopt a method in which the tile body is transported without changing the mounting direction from the patterning process such as pattern printing or uneven pattern formation to the connecting paper pasting process. Although this is preferable, it is impossible to expect this because many steps such as glazing, firing, drying, and finishing are involved between the pattern imparting step and the connecting paper pasting step.

``Object of the Invention'' The present invention has been made in view of the above-mentioned circumstances, and the present invention has been made in view of the above-mentioned circumstances. To provide a new method for manufacturing unit tiles that allows easy checking for differences and eliminates any mistakes in attaching tiles to the wall surface of a building frame, floor surface, etc.

"Structure of the Invention" (Means for Solving Problems) When arranging a plurality of tiles with directional surface patterns and pasting a connecting paper on the surface pattern gathering surface, the back side of each tile is In addition to providing a positioning recess in advance, in the process of attaching the connecting paper, the position or shape of the positioning recess of the tile, which is regulated within the tile storage space, is
A tile array was used that was provided with direction indicating protrusions that could realize a unique matching state.

(Function) Since the matching state between the tiles and the tile storage space is unique, if any of the tiles loaded in the tile storage space is oriented in the wrong direction,
The tile is left floating, resulting in an abnormal storage condition. Therefore, it is easy to distinguish the tile from other normally stored tiles, and the directionality of the surface pattern of all the tiles can be unified to a predetermined direction.

(Example) The present invention will be described below based on drawings showing examples thereof.

The most distinctive feature of the method of the present invention is that a positioning recess is formed in advance on the back side of the tile.
The method is to use a tile array provided with direction indicating protrusions in the process of attaching the connecting paper.

FIG. 1 shows a tile array 5 used in manufacturing unit tiles using rectangular tiles, in which A is a partial plan view and B is a side sectional view. As shown in the figure, the tile alignment body 5 is formed by aligning and dividing rectangular tile storage spaces 5b, 5b, . . . by a joint grid 5a. Receiving surface 5c
A direction indicating protrusion 6 is formed in a protruding manner. The direction indicating protrusion 6 is shaped like a short rectangular bank. The position where the direction indicating protrusion 6 is protruded is on the bisector along the longitudinal direction of the rectangular tile storage space 5b, and is closer to one of the shorter sides. That is, in this example, the tile array body 5 used in the method of the present invention
This is a conventional formwork 2 (see FIG. 4) in which direction-indicating protrusions 6, 6, .

The tile 7 used in the method of the present invention has a positioning recess 7a at a position corresponding to the direction indicating protrusion 6 protruding from the tile alignment body 5, as shown in a perspective view from the back side in FIG. It is formed by drilling. The positioning recess 7a is located in the direction indicating protrusion 6.
It has an internal space that follows the outer shape of the direction indicating protrusion 6, so that the direction indicating protrusion 6 can be accommodated therein. and,
The positioning recess 7a of the tile 7 as described above is formed by deforming the mold when the tile 7 is manufactured by dry molding, or by wet extrusion. When this is the case, the material is extruded into a tile body and then compression molded as appropriate. In addition, the number 8 in the figure
indicates the sole foot of the tile.

(Study of Alternative Embodiment) The direction indicating protrusion only needs to have a unique fitting state with respect to the tile that is fitted into the tile storage space of the tile alignment body. Accordingly, countless variations on its implementation are possible. For example, consider a case where the tile has a square shape and the combination of a positioning recess and a direction indicating protrusion is one set. In this case, the condition that the matching state of the positioning recess of the tile and the direction indicating protrusion in the tile storage space can be unique is that the recessed position of the positioning recess in the back surface area of the tile is at the centroid of the square, All except for the condition that the shape of the positioning recess is a shape that can be accommodated in two directions of the tile (for example, square, rectangle, circle, octagon, etc.). Furthermore, it is not necessary that the direction indicating protrusion and the positioning recess are in a mating relationship;
For example, for the positioning recess 7a of the tile 7 as shown in FIG. 2, the direction indicating protrusion 6 may be a wire-like ultra-fine protrusion (not shown). In other words, the shape and position of the direction indicating protrusion and the shape of the positioning recess are completely arbitrary. However, in the recessed area of the positioning recess of the tile, it is preferable not to drill across or longitudinally across the back surface area of the tile. This is because the bending stress of the tile becomes weaker against the shearing force acting from the surface side. Further, the tile arrangement body 5 is not limited to a structure in which the tile storage space is divided so as to surround the entire periphery of the tiles by the conventional joint grid 2a, but for example, as shown in FIG. It may be something that restricts only two sides. In this case, it is preferable that the direction indicating protrusion 6 is provided with an upward tiling taper as shown in the figure. As described above, the detailed structure of the method of the present invention, the shape of the instruments used, etc. can be changed as appropriate depending on the mode of implementation.

``Effects of the Invention'' As is clear from the above explanation, the unit tiles manufactured by the method of the present invention are those in which the connecting paper is attached with the surface pattern of the tile in the wrong direction. There will be nothing left.
This is because, according to the unit tile manufacturing method of the present invention, the directionality of the tile surface pattern is checked twice. That is, when attaching the connecting paper to the surface pattern collection surface of the tile group, suppose that a tile is placed in the wrong direction. Since the positioning recess of the tile does not match the direction indicating protrusion of the tile alignment body, the tile bulges out from the other surface pattern collecting surface, and the connecting paper cannot be attached in the first place. Also, in the unlikely event that the direction indicating protrusion of the tile alignment body is broken, the direction may be incorrect; When looking at the back side of the tile, this can be confirmed by the arrangement of the positioning recesses formed on the back side of each tile. Therefore, there is no need to notice an arrangement error until the connecting paper is peeled off after each tile has been fixed to the wall or floor of the building structure, as is the case in the past. In other words, the present invention was devised from the course of their work to address a drawback that could not have been predicted by anyone other than those skilled in the art, and moreover, it solves this drawback in the simplest way possible. This is groundbreaking. In addition, providing positioning recesses on the back side of tiles during the tile manufacturing process may seem to increase manufacturing costs, but as mentioned above, once the tiles have been fixed to the structural surface, the tiles may be placed in the wrong direction again. It goes without saying that this is extremely beneficial when considering the effort, time, and cost of peeling off the adhesive and reapplying it.
