Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the construction of an apparatus for manufacturing an exterior material according to an embodiment of the present invention. This manufacturing apparatus mixes cement (not shown) and finely-selected fine aggregates by adding water thereto. A mixer 1 for making mortar, a draining iron plate 3 on which a fixed amount of mortar 2 made by the mixer 1 and then measured by a measuring means (not shown) is placed, and a mortar 2 placed on the draining iron plate 3 And press-in device 5 such as a belt conveyor for transferring the draining iron plate 3 into the press 4 and an initial curing step of the next step. And a transport device 5A that transports the paper to the transport device.

The draining iron plate 3 is used for smoothly dehydrating the mortar 2 as a molding material under pressure and has a drain hole (not shown). When the mortar 2 is pressurized by the mold 5 as described later, excess water added to impart fluidity to the mortar 2 is squeezed out through the draining iron plate 3 and the drain holes. ing.

As a result, a thick slate having a high density is formed while leaving only the water necessary for hardening the cement. Note that a draining cloth (not shown) is applied to the entire upper surface of the draining iron plate 3 so that the mortar 2 can be dewatered without being pushed out from the drain hole by the draining cloth. ing.

On the other hand, as shown in FIG.
The upper die 41, which is a pressing portion, is attached to the ram 43 of the press 4 and moves up and down. In addition, the lower mold 42 serving as a support portion is provided with the draining iron plate 3.
The metal frame 7 that supports the draining iron plate 3 when it is carried into the press 4 and that is formed on the outer periphery of the supported draining iron plate 3 and that forms the end face of the exterior material is provided so as to be freely retractable.

When the draining iron plate 3 on which the mortar 2 is placed is loaded into the press 4, the metal frame 7 is retracted into the lower mold 42 as shown by a broken line so as not to hinder the loading. It has become. In addition, during pressure molding, the pressure rises to the position shown by the solid line, and after the pressure is completed, the molded product is retracted into the lower mold 42 again so as not to hinder the protrusion of the molded product.

Meanwhile, the bottom surface of the upper die 41, which is a press contact surface that presses against the mortar 2, has a number of different patterns for forming the surface pattern of the exterior material. For example, as shown in FIG. The dies P _{1 to} P ₃₀ are attached. By attaching a large number of pattern dies P _{1 to} P ₃₀ in this manner, a fine pattern can be applied to the surface of the exterior material.

The pattern dies P _{1 to} P ₃₀ have, for example, bolts (not shown) suspended from the upper surfaces of the pattern dies P _{1 to} P ₃₀ and are fixed to the upper mold 41 by nuts (not shown). It is attached to the bottom surface of the upper mold 41 so as to be freely combined by the attaching means having the configuration described above.

The combination of the pattern dies P _{1 to} P ₃₀ can be freely changed by freely attaching the pattern dies P _{1 to} P ₃₀ to the upper mold 41 in this manner.

The pattern dies P ₁ -P
By changing the combination of the ₃₀ patterns, for example, the sixth pattern mold P ₆ and the eighth and ninth pattern molds P ₈ , P
_9, by changing the eighteenth pattern mold P ₁₈ the mounting position of the first 23 and second 24 patterns molds P _23, P ₂₄ from the position shown in FIG. 3 to the position shown in FIG. 4, fineness of the surface of the outer package It is possible to give a change to a simple pattern.

When 30 pattern dies P _{1 to} P ₃₀ are attached as in the present embodiment, theoretically 30 ² if the size of the pattern dies P _{1 to} P ₃₀ is ignored. It is possible to manufacture 900 types of exterior materials having different patterns.

As described above, by changing the combination of the pattern dies P _{1 to} P ₃₀ , it is possible to easily change the pattern on the bottom surface of the upper die 41, and thereby, it is possible to form the exterior material having various surface patterns. Manufacturing becomes easy. Further, it is not necessary to prepare the press 4 having a plurality of different pattern surfaces, and the manufacturing cost can be reduced.

Next, a description will be given of a method for manufacturing an exterior material in the apparatus for manufacturing an exterior material having such a configuration.

First, in a mortar kneading step, as shown in FIG. 1, water is added to a cement (not shown) and finely selected fine aggregate by a mixer 1 and kneaded to prepare a mortar 2.

Next, as a mortar transporting step, the mortar 2 produced by the mixer 1 is measured by a measuring means (not shown), and a certain amount of the mortar 2 is placed on a draining iron plate 3.
Thereafter, the draining iron plate 3 is carried into the forming press 4 by the transfer device 5. At this time, the metal frame 7 of the lower die 42 of the press 4 is retracted into the lower die so as not to hinder the loading of the draining iron plate 3 (see FIG. 2).

Next, the mortar 2 is pressed by the upper mold 41 as shown in FIG. As a result, the mortar 2 is spread to a uniform thickness between the upper die 41, the draining iron plate 3 and the metal frame 7, and during this time, excess water added to give fluidity to the mortar 2 is removed by the draining iron plate 3. It is squeezed out through the drain holes to form a dense slate with high density leaving only the water necessary to harden the cement.

Here, when the mortar 2 is pressurized in this way, the surface of the mortar 2 is formed, for example, by the 30 pattern dies P _{1 to} P ₃₀ (see FIG. 3) attached to the bottom surface of the upper die 41 as shown in FIG. A pattern as shown in FIG. 6A is formed.

By the way, when the arrangement of the ₃₀ pattern molds P _{1 to} P ₃₀ is changed as shown in FIG. Has a pattern as shown in FIG. 6B.

As described above, by changing the combination of the pattern dies P _{1 to} P ₃₀ , it is possible to manufacture exterior materials having various surface patterns.

The exterior material having the surface pattern formed in this way is extruded from the press 4 by an extruding member (not shown), and is conveyed by the conveying device 5A to the next initial curing step.

In the initial curing step, a solidified molded product (not shown) is placed on a receiving plate, and is placed in an initial curing room and cured. Thereafter, the molded article is removed from the receiving plate and placed in a wet state or placed in water to be further cured, and finally applied to the one having reached the specified strength, if necessary, by painting or painting. The exterior material is completed by coloring.
