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, as shown in Fig. 5, a roll cutter B with a cutter blade A protruding from the roll surface is used to fit the shape of the tile to be cut. Using the cutting machine, cut the band-shaped inorganic raw material transported by the belt conveyor C as shown in Fig. 4A, and after natural curing, cut the product material E into the solid line state at the opening in Fig. 4 with a punch dicent. It is called flat tile F. In addition, the fourth
In the opening of the figure, the shaded part is the working part that is exposed to the outside when the roof is covered with tiles.

(Problems with the prior art) However, while the above-mentioned conventional method has the advantage of being able to continuously manufacture the flat tiles F, the draining portions G exposed to the outside of the tiles F have the same shape, so the roof surface The exterior had a unified geometric design, and the roof surface had a monotonous appearance.

[Problem to be solved by the invention]

The present invention has been made in view of the points mentioned in -1- above, with the aim of providing a cutting method that can manufacture building materials having continuous M different shapes.

(Technology that led to the solution of Problem 811) In other words, the cutting force method for inorganic building materials of this invention includes circular cutters on the left and right at a required interval, and the force in each circular cutter and the shape of the tar blade are Along with being varied irregularly in the circumferential direction.

These double cutters have uneven cutter blade shapes on the left and right cutters. 1- Roll cutters are formed to be offset from each other in the circumferential direction, and the strip-shaped raw material of an inorganic building material conveyed by a belt-conhair is cut into a groove shape in the center by the double cutter described in 1-. 711 Next, feature 2 is included in which both sides of the groove are cut at regular intervals C in the belt-like direction using J-marked roll cutters.

[Example] Next, the present invention will be explained in detail.

Fig. 1 is a perspective view of a double cutter used in an embodiment of the present invention, Fig. 2 is a perspective view of a roll cutter used in an embodiment, and Fig. 3 A, C, and C are explanatory diagrams of the operation of the embodiment. .

In this embodiment, the cutting force method for inorganic building materials of the present invention is a cutting method for manufacturing a flat tile 1, and is provided with circular cutters 2.3 on the left and right at a required interval. a cutter blade 2a in each circular cutter 2.3;
The shape of the canter blades 3a is irregularly changed in the circumferential direction, and the shapes of the canter blades 2a and 3a are arranged unevenly on the left and right cutters, and the rectangular shapes of the same portions are set to be different. A double cutter 4 is provided, and cutter blades 5a and 5b are protruded from the left and right sides of the roll surface at regular intervals in the circumferential direction, and the left and right cutter blades 5a and 5b are connected to each other by half the width of the flat tile 1c). 2 for the strip-shaped raw material 8 of inorganic building materials conveyed by the belt conveyor 7,
The central portion is cut into a groove shape by the double cutter 4, and then the both side portions 8a, 8b sandwiching the groove 9 are cut at regular intervals in the belt-h direction by the roll cutter 6. After natural curing of the tile material 10 obtained by the above-mentioned cutting, a punch-die set is used to cut the tile material 10 shown in chain lines as shown in FIG.

[Effect]

According to the method described in 1-7, the double cutter 4 is used.

When the raw material was cut into 2 strips of 8 pieces, the cutting line that sandwiched the $ 9 continuously changed into an irregular shape as shown in Figure 3A, and was formed into 1, both side portions 8d and 81]. Since the cut shapes at the same location will be different, the next step is roll force! Shape 4 of the draining part 11 of Ki + tlO obtained by cutting with E = 6
．． ) to Figure 3, J-U (this irregularly changing shape 2.
In addition, the shape of the draining portion 11 changes from one tile to another, and flat tiles 1 having different shapes can be produced continuously.

(,,ga''(,1-) Irregular draining lines appear on the thick surface roofed using the flat tiles described in 1-, and the roof surface does not have a variety of expressions.

Note that the strip-shaped raw material 8 is cut into two by the double cutter 4 while forming grooves 9 at the locations that will become the draining portions.The reason for this is that the draining shape formed by the double cutter 4 is not a straight line, so the roll Raw material 8 by cutter 6
This is because, when cutting, for example, the cutter blade 5a corresponding to the one side 8a may cut beyond the draining part to the other side 8b.

1' Effect] Since this invention is configured as described above, it is possible to continuously produce building materials with different cutting shapes using two cutters. For example, when the building material is a roof tile, this roof tile can be used. This has the effect of making it possible to add a variety of expressions to the roof surface.
