Description

  The present invention is a method for producing an extruded corner material with an embossed pattern in which a corner material such as an outer wall material and a partition wall is extruded using a hydraulic material such as cement, and at the same time, an arbitrary uneven pattern is attached to the surface of the corner material. And an apparatus for the same.

  Extrusion-molded cement boards obtained by kneading and extruding hydraulic materials such as cement with reinforcing fibers and admixtures are often used as outer walls and partition walls of buildings. In the construction of an outer wall or a partition wall using such an extrusion-molded cement board, a corner material may be used for an entrance corner or an exit corner. When a corner material is used, a corner material that is patterned on the left and right wall surfaces is often used on the surface. As a manufacturing method of this kind of corner material with a pattern, there exists a manufacturing method of the extrusion corner material with an uneven | corrugated pattern disclosed by the following patent document 1, for example. In this manufacturing method, an uncured hydraulic material is extruded onto a receiving member having an uneven pattern (embossed pattern) formed on the inner surface, and the pattern forming surface of the hydraulic material is brought into close contact with the receiving member, whereby a corner material with an uneven pattern is obtained. I was able to get it.

By the way, when building the wall surface using a corner material, the extrusion-molded cement board of a pattern (or one side is a flat panel) which is different in right and left of a corner material may be used. In such a case, since the two surfaces of the corner material are also patterned according to the wall surface, corner materials having different patterns on the two surfaces are required. When corner materials with different patterns on these two surfaces are required, it may be manufactured by sticking the extrusion-molded cement boards with different patterns into a corner shape. The corner material with a pattern is manufactured by giving a different pattern to each surface at the time of manufacture of a corner material.
However, in the manufacturing method disclosed in Patent Document 1, an uncured hydraulic material is extruded onto the receiving member, so that it is removed from the receiving member (embossed mold and receiving iron plate) until primary curing is performed and handling strength is generated. I can't. For this reason, an embossing die in a quantity that matches the production cycle from extrusion to curing and demolding is required. Moreover, since the embossed pattern which is different in two surfaces may be employ | adopted for a corner material, according to the kind of embossed pattern to be used, as shown in FIG. 6, the embossing type | mold 1 which satisfies each combination, 3 and 5 had to be prepared. Therefore, it is necessary to prepare as many embossed molds as the total number of the above-mentioned production cycle and the quantity that satisfies all the combinations. The storage place corresponding to the embossing type of this was required, and the inconvenience that management work became complicated occurred. Furthermore, in the case of a conventional integrated embossing mold that simultaneously patterns two surfaces, a pattern must be formed in consideration of removing the embossing mold. For example, two surfaces of the corner material 7 shown in FIG. The embossed pattern in which the vertical pattern 9 is engraved on both 7a and 7b cannot be provided, and the design is restricted.
The present invention has been made in view of the above situation, and a method for manufacturing an extrusion-molded corner material with an embossed pattern capable of imparting different embossed patterns to two surfaces with a small number of embossing molds without performing laborious bonding manufacturing and It is to provide such a device.

And an embossed pattern-extruded corner material manufacturing method for imparting the embossed pattern to the surface of the corner material, wherein separate embossed molds respectively corresponding to the two surfaces of the corner material are provided on the receiving member. After the mounting and the corner material is hardened to a predetermined strength, the two embossing dies are individually removed from each other.

  In this method of manufacturing an extrusion-molded corner material with an embossed pattern, the embossed molds that are in close contact with the two surfaces of the corner material can be individually removed, and the integrated embossed mold can provide a restricted pattern. Thereby, the variation of the embossing pattern provided to two surfaces of a corner material is increased.

  The method for producing an extruded corner material with an embossed pattern according to claim 2, wherein a demolding relief recess is formed in the extruding direction at a corner of the corner material on the entrance corner side, and an embossing die is disposed in the demolding relief recess It is characterized by not.

  In this method of manufacturing an extruded corner material with an embossed pattern, even if the embossed pattern application target surface is a corner, a demolding recess is formed at the corner on the corner of the embossing pattern, and the embossing die is the demolding recess. The two embossing molds provided in close contact with the two corners of the entrance corner can be easily removed without interfering with each other.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of a method for manufacturing an extruded corner material with an embossed pattern and an apparatus thereof according to the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of an apparatus for manufacturing an extruded corner material with an embossed pattern according to the present invention that receives a corner material, and FIG. 2 is an explanation of variations of the embossing mold shown in FIG. FIG. 3, FIG. 3 is a side view of a corner material extruder, FIG. 4 is a view taken in the direction of arrows AA in FIG. 3, and FIG.
As shown in FIG. 1, an apparatus for manufacturing an extrusion-molded corner material with an embossed pattern (hereinafter simply referred to as “manufacturing apparatus”) 100 according to the present embodiment receives a corner material 23 extruded from a base 21, An uneven embossed pattern is given to, for example, the corner of the corner material 23.

  The corner material 23 is extruded by a corner material extruder 25 shown in FIGS. The extrusion molding machine 25 is configured to connect a hydraulic material to the die 21 by connecting the die 21 and the pressure feeding unit 27, a pressure feeding unit 27 that pressure-feeds the hydraulic material, a die 21 in which the extrusion port 21 a is disposed in the manufacturing apparatus 100. And a bent throttle tube 29 to be supplied. The bent throttle tube 29 is bent in an L shape with an inclination angle of 45 °, for example, with respect to the conveyance axis direction of the manufacturing apparatus 100, thereby avoiding interference between the manufacturing apparatus 100 and the pressure feeding unit 27. 21 can be placed close to the manufacturing apparatus 100.

 The extrusion port 21a of the base 21 is formed in an equilateral mountain shape (inverted V shape) that is a right and left object. Further, an inner ball 33 is disposed in the extrusion port 21a, and the middle ball 33 forms a hollow portion 35 having the same cross-sectional shape as the middle ball 33 in the corner member 23 extruded from the extrusion port 21a. A synchronization drive roller 37 and a plurality of auxiliary rollers 39 are disposed in the conveyance path of the manufacturing apparatus 100.

  The synchronous drive roller 37 and the auxiliary roller 39 are formed in an abacus ball shape that rotates around the rotation shafts 37a and 39a and has a small diameter portion at both ends in the axial direction and a large diameter portion at the center. The synchronous drive roller 37 and the auxiliary roller 39 are configured such that the large diameter portion serves as a placement portion 41 and stably supports the corner of the manufacturing apparatus 100. The synchronous drive roller 37 is rotationally controlled in synchronization with the extrusion speed of the corner member 23. That is, the manufacturing apparatus 100 is placed on the synchronous drive roller 37 and the auxiliary roller 39, receives the corner material 23 continuously extruded from the base 21 in synchronization with the extrusion speed, and is moved in the longitudinal direction.

  The manufacturing apparatus 100 includes a receiving iron plate 51 that is a receiving member, and embossing dies 53a and 53b. The receiving iron plate 51 has two receiving surfaces 51a and 51b that extend in the pushing direction of the corner member 23 and face the embossed pattern application target surfaces 23a and 23b of the corner member 23 shown in FIG. For the receiving iron plate 51, for example, an angle material having an equilateral mountain cross-sectional shape can be used.

  The emboss dies 53a and 53b are formed separately and placed on the receiving surfaces 51a and 51b of the receiving iron plate 51, respectively. The embossing dies 53a and 53b are mounted on the receiving surfaces 51a and 51b so that they can be easily attached and detached by a locking structure (not shown). Therefore, the corner material 23 extruded from the base 21 is received by the receiving iron plate 51 on which the embossing dies 53a and 53b are placed, so that the embossed pattern application target surfaces 23a and 23b are in close contact with the embossing dies 53a and 53b. It has become.

  The embossing dies 53a and 53b are individually formed for each of various embossing patterns. In the manufacturing apparatus 100, various embossing dies 53a, 53b, 53c, etc. are mounted in any combination, for example, the embossing dies 53c, 53b shown in FIG. 2 (a) and the embossing dies 53c, 53a shown in FIG. 2 (b). Placed. Thereby, arbitrary patterns can be applied to the two surfaces of the corner material 23 (the embossed pattern application target surfaces 23a and 23b).

Next, a method for manufacturing the corner member 23 using the manufacturing apparatus 100 configured as described above will be described.
The manufacturing apparatus 100 is placed on the synchronous driving roller 37 and the auxiliary roller 39, and the manufacturing apparatus 100 is conveyed in synchronization with the extrusion speed of the corner material 23 extruded from the base 21 by the driving of the synchronous driving roller 37. .

  The corner members 23 pushed out from the base 21 are sequentially pushed out while being placed on the embossing dies 53a and 53b of the manufacturing apparatus 100. At this time, a demolding relief recess 61 is formed in the extrusion direction at the corner of the corner member 23 on the entrance corner side. The embossing dies 53a and 53b are not arranged in the demolding relief recess 61. Thereby, even if the embossed pattern imparting target surfaces 23a and 23b are corners, the two embossing dies 53a and 53b provided in close contact with the two corners can be easily removed without interfering with each other. It is like that.

  In the corner material 23 placed on the embossing dies 53a and 53b, the embossed pattern application target surfaces 23a and 23b are brought into close contact with the embossing dies 53a and 53b, and the concavo-convex patterns of the embossing dies 53a and 53b are transferred. When the corner material 23 is pushed out to a predetermined position of the receiving iron plate 51, the corner material 23 is cut by a cutting machine (not shown) and is transported together with the manufacturing apparatus 100 to a curing store or the like.

 The corner material 23 conveyed to the curing chamber is brought into close contact with the embossing molds 53a and 53b until a predetermined strength is generated, and is primarily cured while being placed on the receiving iron plate 51. The corner material 23 after the primary curing has a handling strength. Accordingly, as shown in FIG. 5A, the embossed pattern application target surfaces 23a and 23b are inverted so as to face upward, and then the receiving iron plate 51 is separated as shown in FIG. 5B.

  Next, as shown in FIG. 5C, after the embossing mold 53a is separated from one embossed pattern application target surface 23a, as shown in FIG. 5D, the other embossed pattern application target surface 23b is embossed. The molds 53b are individually separated. At this time, since the embossing dies 53a and 53b are formed with the mold release relief recess 61 at the corner on the entrance corner side, it is possible to separate the embossing dies 53a and 53b in the vertical direction with respect to the embossed pattern application target surfaces 23a and 23b. . Thereby, there is no restriction on the embossed pattern, and for example, an embossed pattern in which joints exist at right angles to the two surfaces of the corner member 23 can be provided.

  Thus, the corner material 23 separated from the embossing dies 53a and 53b is further cut into a predetermined length, subjected to autoclave curing, and the manufacture is completed as the corner material 23 provided with an arbitrary embossed pattern.

  According to this method of manufacturing an extruded corner material with an embossed pattern, two surfaces of the corner material 23 are patterned by separate embossing dies 53a and 53b, and these embossing dies 53a and 53b are individually demolded. The integrated embossing type can give a restricted pattern, and can increase variations of the embossed pattern. As a result, it is possible to manufacture a high-value-added corner material provided with any different embossed pattern on the two surfaces of the corner material 23.

  Moreover, according to the manufacturing apparatus 100, since the embossed pattern on the two surfaces of the corner member 23 can be formed by rearranging the embossing dies 53a and 53b, it has been conventionally required when the embossing dies are integrated. There is no need to have a single embossing pattern for the combination of embossed patterns, and the storage location and management work can be simplified. Further, even when a new embossed pattern is formed, it is only necessary to manufacture an embossed mold having a new pattern, and it is not necessary to manufacture an integral embossed mold combining conventional embossed patterns.

  In the above embodiment, the corner member 23 having the embossed pattern on the corner is obtained by using the base 21 having the equilateral mountain-shaped extrusion port 21a. However, the manufacturing method and the manufacturing method according to the present invention By using the base 21 having a V-shaped extrusion port, the apparatus can similarly obtain a corner material with an embossed pattern on the protruding corner side. Moreover, it is possible to demold an arbitrary embossed pattern by continuously arranging and using an embossed mold divided into a plurality in the circumferential direction for a corner material having a concave arcuate surface. .
