Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cutting method for manufacturing inorganic building materials such as flat roof tiles.

[Conventional technology]

When manufacturing building materials such as flat tiles from inorganic raw materials such as cement and clay, conventionally a roll cutter B is used, as shown in Figure 6, with a cutter blade A protruding from the roll surface to fit the shape of the tile to be cut. Then, as shown in FIG. Cutting the raw materials,
After natural curing, the building material E was cut into the solid line shape shown in Figure 4 using a punch die set to form a flat tile F. In addition, in the opening of FIG. 4, the hatched part is the working part exposed to the outside when the roof is covered with tiles.

[Problems with conventional technology]

However, while the above-mentioned conventional method has the advantage of being able to continuously manufacture flat tiles F, since the draining portions G exposed to the outside of the tiles F have the same shape, as shown in FIG. The problem was that the appearance of the roof surface was unified with a geometric design, making the expression of the roof surface monotonous.

[Problem to be solved by the invention]

In view of the above-mentioned problems, the present invention was made with the aim of improving the cutting method that can produce building materials having continuously different shapes.

[Technology that led to solving the problem]

That is, the method for cutting inorganic building materials of the present invention cuts a strip-shaped raw material of inorganic building materials conveyed by a belt conveyor,
It is a method of cutting the above-mentioned method by cutting with a roll cutter 4 times to the left and right to divide the middle part in the width direction into left and right parts, and to cut the two divided left and right side parts at predetermined intervals in the belt-like direction, respectively. Of the cutter blade of the roll cutter that cuts the strip-shaped raw material, the shape of the blade of the part that divides the material into two parts is changed irregularly in the direction of force around the circumference of the roll cutter. It is characterized by a continuous and uniform change in the end face of the building material.

〔Example〕

Next, the present invention will be explained in detail.

FIG. 1 shows the l! used in the embodiment of this invention. - A perspective view of Lucanotar, 2nd LA A, tJ are operation explanatory diagrams of the embodiment,
Figure 3 shows the state of use of the building materials obtained in the example.7 No I of this invention! In this embodiment, the cutting force method for solid building materials is a cutting force method for manufacturing flat tiles 1, and is a cutting force method for manufacturing flat tiles 1.
is cut into a 1-1 cutter 5 having a cutter blade 4 as shown in FIG. In addition, the cutter blade 4 of the double roll cutter 5 is a method of cutting the left and right side portions 3a, 3ki4 divided into two at predetermined intervals in the belt-like direction by rotating the roll cutter 5.
By irregularly changing the blade shape of the dividing portion 4a, the above-mentioned both side portions 3a, 3b
The end face of each tile 1 obtained by cutting the tile 1 (in the case of this example, the part that will become the draining part 6 of the tile 1 shown in the opening of FIG. 2) is continuously changed and divided into two parts. In addition, in FIG. 2A, the symbol A is a bisecting line.

Then, the tile material 7 obtained by the above cutting is natural tq
Thereafter, using a punch-die set, the chain line portion is cut off as shown in FIG. 2 +1 to produce the tile 1 shown in solid line.

(Function) According to the method described in 1, when the strip-shaped raw material 3 is divided into two parts 4 on both sides 3d and 3b by the roll cutter 5, the dividing line A is irregularly shaped as shown in Fig. 2A. Since it changes continuously, for example, the cuffer blade 4 that divides into two
Assuming that three types of patterns a are formed in the circumferential direction of the roll cutter 5 and that the raw material 3 is cut into three pieces in the strip direction for each rotation of the cuffer 5, tiles 1 with different shapes of the end faces 6 are formed. , for each rotation of the roll cutter 4, 3 pieces (7a, 7h, 7c) can be obtained with one side of the force 2a, and 3 pieces (7d, 7e, 7f) can be obtained with the other side of the force 3tl. Thus, a total of six roof tiles 1 with different draining shapes can be manufactured.

In this way, tiles 1... with different shapes of the draining portions 6 can be manufactured continuously, so the roof surface covered using a mixture of these tiles 1... has defects as shown in Fig. 3. Regular draining lines are created, and the roof does not have a variety of expressions.

[Effect W] Since this invention is configured as described above, it is possible to continuously produce building materials with different cutting shapes.For example, when the building material is a tile, the roof surface covered with this tile can be It has the effect of being able to give various expressions.

Claims (1)

[Claims] (1) A strip-shaped raw material of inorganic building materials transported by a belt conveyor is cut by rotating a roll cutter to divide it into left and right halves at the middle part in the width direction, and
In this method, the left and right sides of the two parts are cut at predetermined intervals in the strip direction, and the blade shape of the cutter blade of the roll cutter that cuts the strip material is set according to the circumference of the roll cutter. A method for cutting an inorganic building material, characterized in that the end faces of each building material obtained by cutting the both sides are continuously changed by irregularly changing the direction.
