Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of mixing and arranging individual tiles as a pre-process in manufacturing unit-laminated tiles. Incidentally, a unit-attached tile is a tile unit in which a plurality of tiles are arranged, for example, in the form of vertical and horizontal joints, and a base sheet is attached to the front or back of this tile unit, and is generally used in hand-tiled construction methods. .

[Problems to be solved by conventional technology and invention]

There are two types of unit tiles: patterns (patterns) and solid colors. Regardless of patterns, in the case of single-colored tiles, there may be various causes such as variations in the particle size distribution of the raw materials, variations in the raw materials due to segregation in the hopper, or differences in the firing position inside the kiln, even if the tiles are of the same color. Differences in shading occur from lot to lot.

Therefore, if unit tiles are manufactured from each lot with different shades and a large number of these tiles are used to tile a large area such as the ceiling, walls, or floor of a building, unevenness in color shading will occur over the entire construction surface. This caused the appearance to deteriorate.

In order to prevent the above, in the past, individual tiles were randomly picked out from each lot by hand and then assembled and arranged to produce unit tiles, but this required skill and was inefficient. It was hot.

The object of the present invention is to solve the problem of the above-mentioned mixed arrangement of tiles without uneven shading, which has conventionally been done manually, in a simple manner.

[Means for solving problems]

According to the present invention, the above object is to classify a large number of tiles having the same color but different densities into a plurality of tile groups each having substantially the same densities, and to The tiles are fed in a boosted manner by a feed conveyor having a dam stop device, and the tiles are placed in a predetermined order of the rows of tile units to be formed by individually opening and closing said stop devices according to an operating program. The tiles, whose postures have been corrected on the transfer path, are transferred onto a discharge conveyor, and the rows of tile units are sequentially shifted in a direction perpendicular to the longitudinal direction of the rows onto the collecting conveyor, so that they are closely spaced. In the tile unit formed in this way, the tiles from each tile group having different densities are arranged so as to be adjacent to each other in the vertical and horizontal directions. This is accomplished by a mixing method.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a plan view showing an apparatus for implementing the method of the present invention, FIG. 2 is a side view showing the main parts of FIG. 1, and FIG. 3 is a view of the controller included in the apparatus shown in FIG. FIG. 3 is a diagram showing an operating program.

The method of the present invention will be explained by taking as an example a case where nine rectangular tiles are arranged vertically and horizontally in a collective arrangement to form a 30.3 cm square tile unit.

From the right side of Figure 1, three groups of tiles A, B, and C of the same color but different densities are successively conveyed on horizontally parallel supply conveyors A', B', and C', respectively. is sent to the left. (The above tile groups A, B, and C, which have different densities, are classified using a color machine, for example.) To simplify the explanation, tile groups A, B, and C are each colored darker than the standard color. , a standard color, and tiles that are lighter in color than the standard color. The leading tiles of each tile group A, B, C are stopped by stopper devices S ₁ , S ₂ , S ₃ provided near the front ends of conveyors A', B', C', respectively. Each tile group A, B, C on the supply conveyors A', B', C' is in a pressed state.

A sorting device 1 is provided near the front ends of the supply conveyors A', B', and C'. The sorting device 1 comprises a wide horizontal mixing conveyor 2 directly following the front end of the supply conveyors A', B', C';
A pair of vertical control conveyors 4 are provided closely above and forming a converging transfer path 3 forwardly on the mixing conveyor. The minimum width of the transport path 3 mentioned above is slightly larger than the individual tile width. Further, a horizontal discharge conveyor 5 is provided following the front end of the mixing conveyor 2.

A controller 6 for controlling these stopper devices is provided on the sides of the stopper devices S ₁ , S ₂ , and S ₃ . As shown in Figure 2, each stopper device
S ₁ , S ₂ , S ₃ feed conveyors A ₁ , A ₂ , A ₃ at one end
It is equipped with a stopper 7 having an L-shaped cross section that is pivotally connected to a stationary part directly below it, and a fluid pressure cylinder 8 that rotates the stopper 7 up and down.
It is designed to be operated individually by.

The operating program of the controller 6 shown in FIG. 3 will be explained. The numbers indicate an example of the operating order of the stopper devices S ₁ , S ₂ , and S ₃ , and the ◯ marks indicate the release timing of each stopper. That is, at a first point in time the stopper device S ₁
is released to allow the transfer of the dark colored tiles, and at a second point in time the stopper device _S2 is released to allow the transfer of the standard colored tiles.

Next, to explain the operation, as mentioned above, the tile groups A, B, and C dammed on the supply conveyors A ₁ , A ₂ , and A ₃ are controlled by the respective stoppers 7 according to a program set in the controller 6 in advance. Release (down)
As a result, the first tile moves forward, and when the movement is finished, the stopper 7 rises to stop the succeeding tile.

If the operating program is set up as shown in FIG. 3, the order in which the tiles move forward upon release of the stopper becomes ----------, and the same cycle is repeated thereafter.

The tiles sent out individually are moved onto the mixing conveyor 2, corrected in posture by the convergent transfer path 3 formed by the control conveyor 4, and then sequentially sent to the discharge conveyor 5, where they are temporarily stopped by a stopper (not shown). 3
Then, each row of three tiles is shifted and discharged from the discharge conveyor 5 in a perpendicular direction by the shifter 9 and transferred to the collection conveyor 10.

A tile unit consisting of nine tiles mixedly arranged in this manner is shown in FIG. As can be seen from the figure, vertically and horizontally adjacent tiles in one tile unit have different densities, so no color unevenness is observed in the tile unit. Also, since tiles of a standard color are adjacent between tile units adjacent in the vertical and horizontal directions, unevenness will not be noticeable when pasted over a wide area.

The controller mechanism described above may be electrical or mechanical. In short, any device that can operate the three stopper devices S ₁ , S ₂ , S ₃ according to a preset program is sufficient. Furthermore, the type of stopper is not limited to one that stops the tile at the front of the tile, but may also stop the tile by clamping from the side edge or by pressing from the back side. Further, the number of tiles per tile unit is not limited to nine, but can be increased to 100 per tile unit using, for example, 3 cm square tiles. A base sheet is attached to the tile unit to create a unit-attached tile.

It is also possible to use the principles of the present invention to make the pattern stand out by arranging tiles of different colors instead of tiles of different densities.

[Effects of the Invention] Since the present invention is constructed as described above, tile mixing can be automated using a simple device, and labor savings can be achieved. Furthermore, by arbitrarily setting the operating program of the controller, it is possible to make the unevenness of shading less noticeable as a whole when unit-attached tiles are attached to a wide construction surface.
