DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column made of glued laminated lumber and a decorative veneer attached to an outer peripheral surface of the column. In this case, the present invention relates to a floor column processing apparatus for forming a cutout for fitting a small wall into an end of a floor column.

[0002]

2. Description of the Related Art As a floor pillar in place of natural wood, an artificial floor pillar in which a laminated wood is used as a core material, which is processed into a cylindrical shape, and a decorative veneer is wound around its periphery is known (for example, a real floor pillar). No. 56-111860).

[0003] The artificial floor column A has, for example, a structure as shown in FIG. That is, a decorative veneer 2 covering the periphery of the core material 1 is adhesively bonded to an outer periphery of a core material 1 made of a laminated material processed and formed in a columnar shape. 3 to 5 mm of the uneven pattern M which is pressed by, and is formed so as to have a form similar to the skin of a natural tree. According to such a floor column A, the height dimension and the like can all be standardized and manufactured, so that workability such as installation work on site can be improved,
In addition, there is an advantage that costs can be reduced as compared with natural trees.

[0004]

By the way, the floor column A is
As shown in FIG. 16, it is mainly used between the floors B, and small walls 3, 4, etc., which are stepped right and left, are joined to the upper end thereof with the front surface exposed. Therefore, it is necessary to provide a notch having a complicated shape at the upper end of the floor column A for joining these small walls 3, 4 and beams.
Simple notches and straight grooves can be easily and almost automatically formed by electric saws, electric saws, electric planes, etc., but recesses with right angles have disc-shaped blades. With an electric saw or a thread saw that cuts while penetrating in the vertical direction, it has been difficult to form such a saw.

[0005] Further, according to the router in which a cutting blade having a predetermined angle with respect to the rotation direction is provided on the surface of the cylindrical rotating body, a notch having a complicated shape can be formed. However, since the notch is formed by the cutting blade on the surface of the cylindrical rotating body, even if a convex right-angled corner can be formed, if a concave right-angled corner is to be formed, In addition, the corner portion becomes an arc shape along the outer peripheral surface of the rotating body. Therefore, it is not suitable for an operation for forming a cutout for fitting a rectangular small wall panel into a floor column.

[0006] As described above, the floor column A itself is standardized by artificially forming the floor column A using a laminated wood, and the formation itself of the cutout portion in the floor column A itself is a single operation. However, since the shape of the notch itself is complicated, the formation of the notch had to rely on a manual operation by a skilled operator. Therefore, the formation of the notch in the floor column A is an obstacle, and it has not been possible to reduce the cost of the artificial floor column A, shorten the manufacturing period, and the like.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it easy to form a cutout for fitting a small wall or the like in an artificial floor column. To reduce the manufacturing cost and the manufacturing period.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to forming a cutout for fitting a rectangular small wall to the floor column when the column is installed between floors or the like.

The router machine is disposed so as to be movable back and forth, left and right, and cuts the floor column to form a notch, and transports the notch forming position of the floor column to a predetermined position, and the position thereof. And a work table fixed with It was used as a solution.

[0009]

According to the above construction, when forming the notch for fitting the end of the rectangular small wall, when forming the concave right-angled corner of the notch, the apex of the corner is used. By drilling a hole in the portion in advance with a drilling machine, when a notch is formed by a router, the corner portion becomes a hole made by the drilling machine. Therefore, when the small wall is fitted into the notch, the corners of the notch remain along the outer peripheral surface of the router and do not become an obstacle, unlike the case where only the router is formed.

Next, a method of processing the floor column A by the floor column processing apparatus C will be described. First, as shown in FIG. 12, a floor column A (before the hole g is formed) that has been processed in advance is transported to the drilling machine D. Then, the floor column A is placed on the roller conveyor 22 with the upper end side facing forward and the side provided with the notches a, b, and c facing upward. The roller conveyor 22 is operated until it comes into contact.

At this time, the side surface of the notch c side is fixed ruler 23
In addition, when one side of the front part d of the floor column A passing under the stopper 24 abuts on the guide column 25, the floor column A is guided to the fixed ruler d side.
When the front surface of the notch a of the floor column A abuts against the stopper 24, the roller conveyor 22 is stopped, and the air column 26c of the pressing unit 26 presses the floor column A onto the work table 13 to perform work. It is fixed to the table 13.

Next, the electric drill 11 and the air cylinder 19 are operated to move the drill 11b downward while rotating, thereby forming a hole g in the floor column A. At this time, the depth of the hole g is regulated by the limit switch 21 that contacts when the drill support 17 moves downward.

Next, as shown in FIG. 12, the floor column having the hole g formed therein is transported to the first router processing apparatus E.
In the first router E, the floor column A is placed on the work table 32 in an inverted state. Then, the roller conveyor 41 is operated until the front surface of the floor column A on the side of the cutout portion abuts on the stopper 38. At this time, floor column A
Is transported on the roller conveyor 41 with the left and right edges regulated by two fixed rulers.

Then, the router 30 is returned to the front end side of the floor pillar A, and is moved by the air cylinder 37 to the other side edge side of the front part d of the floor pillar A. Then, a corner is cut off in the same manner as one side edge of the front part d of the floor column A, and is processed like the floor column A shown in FIG.

Next, the floor column is transported to the second router F. Also at this time, the floor column A is inverted and placed on the work table 46. Then, similarly to the first router machine E, the floor column is conveyed by a roller conveyor until the front surface of the notch a side of the floor column contacts the stopper, and is pressed from above by the air cylinder 52 so that the floor column A is placed on the worktable 46. Transport to Then, the notch i of the floor column A shown in FIG. 14 is formed by moving the router 44 back and forth and right and left while rotating.

At this time, if the router 44 tries to cut the depth of the notch i as it is, a large load is applied to the router 44. Therefore, the height of the notch i is reduced to 1/3 of the depth of the notch i by the vertical moving part 44c. Then, the height of the lower end of the router 44 is adjusted, and cutting is performed to a depth of 1/3 of the notch i. Next,
The height of the router 44 is lowered by the depth of 1/3 of the notch i, and the floor column A is cut. Thereafter, the router 44 is further lowered to cut the remaining portion of the notch i. As described above, according to the floor column processing apparatus C of the present embodiment, first, the hole g is formed in the concave corner of the notch i for fitting the small wall with the drilling machine D, so that the router 44 cuts out the hole g. Even when the portion i is formed, there is no remaining uncut portion along the outer peripheral surface of the rotating body 44b of the router 44 at the concave corner of the notch i. Therefore, the small wall can be fitted without further processing the notch i, and the formation of the notch i in the floor column A can be simplified.
The notch i can be formed almost automatically by the drilling machine D and the router 44, so that the cost of the floor column A and the manufacturing period can be reduced. The floor column processing apparatus of the present invention is not limited to the above-described embodiment, and specific configuration requirements such as the shape, dimensions, and material of each member can be appropriately changed upon implementation.

[0046]

As described above in detail, according to the floor column machining apparatus of the present invention, first, a notch having a concave corner for fitting a small wall with a drilling machine is provided at the vertex of the corner. By making the holes, even if the notch is formed by the router, there is no uncut portion along the outer peripheral surface of the router at the corner. Therefore, the small wall can be fitted without further processing the notch,
The formation of the notch in the floor column can be simplified, so that a notch having a complicated shape, such as when a stepped small wall is fitted to the floor column, can be easily and almost automatically formed. As described above, since the notch can be formed almost automatically by the drilling machine and the router, the cost of the floor column and the manufacturing period can be reduced.
