DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for continuously producing a corrugated corner material having a concavo-convex pattern used for a corner portion of a building exterior wall, a partition wall or the like by extruding a hydraulic material such as cement. The present invention relates to a method and an apparatus for producing a patterned corner material.

[0002]

2. Description of the Related Art Conventionally, in an architectural panel such as an outer wall or a partition wall made of an extruded cement board or the like, an uneven pattern (emboss pattern) is provided on the surface thereof to improve the design. When a wall of a building is constructed using such a panel with a concavo-convex pattern, a corner material such as an outgoing corner material and an ingoing corner material is also configured as a corrugated corner material from the aspect of design of the building. Is common.

This corner material with a concavo-convex pattern is usually formed by bonding two flat panels at a right angle.
In this case, a right angle corner material is obtained by obliquely cutting the bonding surface of the flat panel at 45 ° and bonding the oblique cut portions together with an adhesive. However, in this method, in order to bond the corner material, a panel cutting process and a bonding operation are necessary, which has a problem that the number of processing steps is large and a manufacturing cost is high, and also a problem that the adhesive is deteriorated in a long term. It contained serious problems such as a fear that the durability of the bonded portion would be reduced.

Therefore, as an alternative method, a method of transferring a concavo-convex pattern by pressing and forming a mold plate with a concavo-convex pattern on a corner material integrally formed by extrusion, or simultaneously extruding a corner material. There has been proposed a method as shown in Japanese Patent Application Laid-Open No. 10-193315 for imparting an uneven pattern. However, the former method of transferring a concavo-convex pattern by press molding after extrusion molding can be used for the production of a panel without a hollow portion and a corner material, but in the case of a panel with a hollow portion and a corner material, the panel shape is formed by pressing. However, there is a problem in that it cannot be used because it is deformed.

On the other hand, in the latter method disclosed in Japanese Patent Application Laid-Open No. Hei 10-193315, an uncured corner material is extruded into a receiving member having a linear receiving groove in which an uneven pattern is formed on the inner wall surface, and a molding surface thereof is formed. The concave and convex pattern is transferred by bringing the concave and convex pattern into close contact with the inner wall surface of the receiving member on which the concave and convex pattern is formed. Extrusion molding is possible even for a corner material with a concave and convex pattern having a hollow portion. However, in the case of this method, the corner material cannot be removed from the receiving member during the curing time until the manufactured corner material has a strength that can be released from the mold, so that the number of the corner materials to be manufactured during the curing cycle period is not sufficient. It is necessary to prepare a receiving member having only an uneven pattern.

In particular, a receiving member having an uneven pattern is more expensive than a normal flat receiving member, and it is necessary to prepare a large number of such receiving members. In addition, since the portion to which the concavo-convex pattern is provided is different between the entering corner material and the outgoing corner material, the corner member cannot be used also as the receiving member, and the receiving member must be prepared separately. Furthermore, even if molding defects of the concavo-convex pattern occur during extrusion molding, it cannot be confirmed until curing is completed. Had to be disposed of as waste.

[0007]

Another object of the present invention is to provide a method and an apparatus for manufacturing a corner material with a concavo-convex pattern, which can use an inexpensive ordinary flat receiving member and can also use the receiving member for forming a corner material and a corner material. To provide.

Another object of the present invention is to make it possible to early detect a molding defect of an uneven pattern at the stage of a raw sheet before the corner material hardens, and to return the defective corner material to a molding machine as it is and reuse it. Accordingly, it is an object of the present invention to provide a method and an apparatus for producing a corner material with a concavo-convex pattern, which can minimize defective products to be disposed of as waste. A further object of the present invention is to provide a method and an apparatus for manufacturing a corner material with a concavo-convex pattern, which can economically produce a corner material having a concavo-convex pattern with less deformation and good quality.

It plays a role in preventing leakage from 8 to the outside. In addition, in order to improve the patterning, the tip of the introduction guide 9 is 0 to 30 from the vertex of the pattern on the lower horizontal portion of the endless belt 4 inside the base 3.
mm, preferably up to 20 mm.

The guide roller 5 on which the endless belt 4 is hung has a function of pressing the endless belt 4 against the hydraulic material in the base 3 and synchronizing the endless belt 4 with the extrusion speed of the hydraulic material. A large number of receiving rollers 11 are provided below the endless belt 4 in opposition to the endless belt 4 to receive the uncured corner material raw plate 12 extruded from the base 3 and to increase the extrusion speed. Corner wood board 1 in tune with
2 can be transported.

The receiving roller 11 and the endless belt 4 are installed so as to be parallel to the base 3 by a predetermined distance, and after passing through this section, the receiving roller 11 is slanted downward so that the interval between the two gradually separates. It is configured so that there is no sudden step.

And is pushed out of the base 3 together with the hydraulic material. The hydraulic material used here is mainly composed of cement, aggregate, and fiber.

The hydraulic material is extruded into a predetermined corner material (a corner material or a corner material) by being extruded from the die 3. The hydraulic material extruded in this way is used as a corner material raw plate 12 with its lower surface being received by the receiving roller 11 and the concavo-convex pattern 7 of the endless belt 4 being closely attached to the upper surface in synchronization with the extrusion speed. Conveyed. Then, after the corner blank 12 is conveyed by a predetermined distance, the receiving roller 11 is installed obliquely downward, and is gradually separated from the endless belt 4.

In this way, the concavo-convex pattern mold 7 of the endless belt 4 is released from the corner material blank 12 and the corner material blank 12 having a predetermined surface provided with a concavo-convex pattern is manufactured. The corner material green plate 12 provided with the uneven pattern is cut to a predetermined length by a cutting machine that moves in synchronization with a transfer speed at a predetermined position while being transferred on the receiving roller 11.
Then, the corner material raw plate 12 cut to a predetermined length,
It is received by the receiving member 13 sent from the lower part of the receiving roller 11 in synchronization with the conveying speed, conveyed to the curing position, and cured while being placed on the receiving member 13.

The corner material raw plate 12 is cured and cured for a predetermined time, then is completed as a final product through a finishing process, and is shipped as a corner material with a concavo-convex pattern (a corner material, a corner material). In addition, as shown in FIG. 3, two or more corner materials can be simultaneously formed by extruding the corner material raw plate 12 in multiples. In addition, both the corner material and the corner material can be manufactured by the same method regardless of the presence or absence of the hollow portion.

According to the above method, the following effects can be expected. (1) A corner material with a concavo-convex pattern (a corner material and a corner material) can be continuously and efficiently manufactured by extrusion, regardless of the presence or absence of a hollow portion. (2) Since the receiving member can also be used for the production of the corner material and the corner material, it is only necessary to prepare the receiving member for the curing cycle.
Moreover, since the receiving member itself can be an inexpensive flat-structure receiving member, the manufacturing cost can be reduced.

(3) Not only right-angled corner material and right-angle corner material,
Similarly, the R corner material can be manufactured as a good quality corner material with a concavo-convex pattern while minimizing deformation during molding. (4) Even if a product with poor patterning occurs during molding, it can be found early at the stage of the raw plate from which the endless belt has separated, so the defective product can be returned to the raw material inlet of the extrusion molding machine and reused Thus, the generation of waste can be reduced, and the cost can be reduced by reducing the number of defective products.
