DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for forming a tile body by a forming press machine and supplying a two-layered clay to a press die in a dry tile body forming apparatus.

[0002]

2. Description of the Related Art Conventionally, a two-layer tile T of this kind is composed of a base clay TA serving as a substrate portion and a surface clay TB serving as a surface portion, as shown in FIGS. There are several types of the clay TB, for example, the base clay TB2 and the mixed clay T
As a device for forming a colored pattern by B1 and TB3, as a device for forming the two-layer tile T, as shown in FIG. The slide surface 5 is formed in the same plane as the upper end of the four-peripheral frame 3. A base supply frame 6 for supplying the base clay TA of the tile T along the slide surface 5;
A surface layer supply frame 7 for supplying B is appropriately connected to an actuating means, and both supply frames 6 and 7 are formed so as to be uniformly supplied to the molding recess 4 of the lower die 1. An upper die 8 is provided above the lower die 1 so as to be vertically movable.

[0003] When the two-layer tile T is formed by the apparatus provided as described above, for example, a predetermined amount of the base clay TA is put into the base supply frame 6, and the base supply frame 6 is lowered by the operating means. The base clay TA is introduced into the lower mold 1 by being moved upward, and then a predetermined amount of the base clay TB2 and the mixed clay TB1 are added to the surface layer supply frame 7 by appropriate means according to the coloring pattern. TB3 is mixed and thrown in, and the surface layer supply frame 7 is moved onto the lower mold 1 and the base clay T charged earlier is thrown.
A, and the upper mold 8 was lowered in this state to perform tile molding.

At the time of this supply, since the comb member 44 is interposed in the front part, three types of mixed surface layer clay TB are mixed.
1, TB2 and TB3 are bar members 44a of the comb member 44.
6, the mixture is uniformly supplied onto the base clay TA in a state where the mixture is diffused and the mixing is promoted as shown in FIG. 6. When the supply is completed, the moving conveyor 40 is returned to the original standby position. . When the moving conveyor 40 is returned to the original position, the upper die 8 is lowered and the two-layer tile T is pressed. Hereinafter, the same operation is performed, and the two-layer tiles T are sequentially pressed.

[0024] Since the above structure is adopted, particularly when the surface clays TB1, TB2 and TB3 are supplied,
Supply port 22 between first hopper 22 and third hopper 24
The three slit-shaped holes 22b and 24b are respectively formed at positions shifted from each other at the positions a and 24a, and a surface layer clay of mixed color is formed on the carrier side of the conveyor 28 of the conveyor truck 26 from the three slit-shaped holes 22b and 24b. TB1 and TB
3 is supplied in the form of a strip to the shifted position, while the surface layer clay TB2 of the blurred base color is uniformly supplied by the second hopper 23, and the conveyor truck 26 is thus supplied.
Surface clay TB supplied to the carrier side of the conveyor 28 of FIG.
1, TB2 and TB3 are the conveyors 28 of the conveyor cart 26
Is moved to the side of the mixing device 33 arranged orthogonally while being placed on the carrier side of the carrier, and the conveyor 28 is intermittently rotated with respect to the width direction of the gutter 34 of the mixing device 33 so as to be supplied in a band shape. The mixed kneaded clay TB1 and TB3 are supplied in a divided state,
In this state, when the mixing device 33 is vibrated to vibrate the surface layer clays TB1, TB2, and TB3 that are supplied in a divided state and are advanced while mixing them, the mixing clay TB1, TB3 as in the related art is advanced.
Can be eliminated and a basic blending of a better mixed blur pattern can be achieved.

FIG. 7 shows a modification of the apparatus. In place of the grizzly 36, an opening in the gutter 34 is provided.
A plurality of movable plates 5 connected at predetermined intervals by a connection shaft 50a
0 are arranged vertically. The movable plate 50 is horizontally operated by a moving means in the right and left directions via the connecting shaft 50a, and is composed of three types of surface layer clay TB.
1, TB2 and TB3 can be mixed by sifting at the opening side in the gutter 34 and supplied onto the belt 42 of the lower moving conveyor 40.
Since the powder of the surface layer clay TB1, TB2, TB3 does not scatter around, a good mixing device can be configured.
