BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for manufacturing a corner material and a corner material using scraps of an outer wall material of a building such as a siding board, and a method of manufacturing the same.

[0002]

2. Description of the Related Art Conventionally, in a building such as a private house, a siding board is often used as an outer wall material. The siding board is formed into a predetermined length in a manufacturing plant, cut to a required size at a construction site, and used as a wall material on each side of the house, and a number of odd end pieces are produced. Further, at the outer corners or inner corners of the wall and the wall, an out corner material or an in corner material having a flat L shape is separately produced in a factory and used as it is at a building site.

On the other hand, the outer corner material for the outer wall (the same applies to the inner corner material) is manufactured as follows. That is, the fixed-size siding board manufactured previously is cut into a plurality of pieces with a predetermined width. Then, an adhesive tape is stuck on the surface of each siding board formed in a rectangular shape so as to straddle the center line in the longitudinal direction, and at the same time, a V-shaped notch having a cross section substantially 90 degrees from the back along the center line. Insert The pressure-sensitive adhesive tape is attached because the rectangular siding board is divided into two when the cut grooves are formed, and when the rectangular siding board is separated, it is difficult to join later. Next, an adhesive is applied to the V-shaped cut surface, the two surfaces are joined to each other to form a flat L shape, and after drying, the adhesive tape is peeled off. I was going to manufacture corner materials.

[0004]

The odd scraps of many siding boards from the construction site are all disposed of as industrial waste, and the disposal is usually performed by a contractor for a fee. However, there is a problem that waste material is wasteful and construction cost is increased because scraps that can be reused, for example, as much as necessary, can be taken out as much as necessary but discarded. Further, in the manufacturing process of the corner material or the corner material, it is necessary to remove the adhesive tape from the temporarily fixed corner material or the corner material after the adhesive is hardened, so that the corner material or the corner material is removed. There was a problem that when the amount was large, it was necessary to perform a difficult work.

[0005] Therefore, the present invention is to reduce the construction cost and to reduce the construction cost by using the scraps such as siding board and the like from the construction site to produce the corner material and the corner material. It is an object of the present invention to provide a manufacturing apparatus and a manufacturing method of an outside corner material and a corner material for an outer wall, which can easily manufacture a corner material.

[0006]

In order to achieve the above object, an apparatus for manufacturing an outer corner material and an outer corner material for an outer wall according to the present invention is provided with a cutting device for cutting an outer wall material such as a siding board into a predetermined size. A pair of plate materials cut by the cutting device and a matching device for positioning and aligning the outgoing corner material and the ingoing corner material temporarily fixed with an adhesive by abutting a pair of plate materials into an L-shape, and the cutting device is a base. On the horizontal upper surface, a circular saw whose saw blade can be set to a vertical surface or an inclined surface forming 45 degrees with the vertical surface is installed, and furthermore, reciprocates on the horizontal upper surface of the base in a direction perpendicular to the drive shaft of the circular saw. A movable table, a clamping member for clamping and fixing an outer wall material of a predetermined size is provided on the movable table, and the aligning device is provided with a pedestal for positioning and supporting the outer corner material and the inner corner material; The above-mentioned corner material and corner material are attached to the pedestal to increase the adhesive strength. For firmly provided a pressing member for pressing and fixing, further comprising a structure mounted air attacker for driving the needle in a location abutting the external corner member-internal corners material on one side of the cradle.

[0007] Further, in the manufacturing method, the edge material of the outer wall material such as a siding board to be discharged from a building site is cut into a predetermined size and cut at the center in the longitudinal direction while being held and fixed to a holding member of a cutting device. To form a pair of plate material units whose cut surfaces make approximately 45 degrees with each other, these cut surfaces are butted against each other and joined with an adhesive to form a temporarily fixed outgoing corner material / ingoing corner material having a plane L shape, The two corners forming approximately 90 degrees of the corner material and the corner material are positioned and supported on the upper surface of the pedestal of the alignment device, and the upper surface is pressed and fixed by the pressing member of the alignment device to the butt joint surface. The needle was driven into connection by an air attacker, and then dried.
