[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a semi-finished product for floor pillars in which a veneered veneer is wound on the outer surface of a cylindrical core material made of laminated wood and engraved with an uneven pattern similar to that of natural wood. The present invention relates to an uneven pattern engraving device for.

[0002]

2. Description of the Related Art Conventionally, as a floor pillar to replace natural wood, an artificial floor pillar is known in which laminated wood is used as a core material, which is processed into a cylindrical shape, and a decorative veneer is wound around the core material. No. 56-111860). This is a structure as shown in FIG. 6, for example. That is, this is one in which a decorative veneer 2 that covers the periphery of the core 1 is adhesively bonded to the outer periphery of the core 1 made of laminated wood that has been formed into a cylindrical shape.
The surface of this floor pillar is pressed by a roller and is 3 to 5 mm.
The uneven pattern M of No. 3 is attached, and it is applied so as to have a form similar to that of natural wood.

According to such a floor pillar, since it is possible to standardize all the height dimensions and the like, it is possible to improve workability such as on-site installation work, and to compare with natural wood. Therefore, there is an advantage that the cost can be reduced.

[0004]

By the way, in the above-mentioned floor pillar, it is necessary to wind a decorative veneer around the outer periphery of the core material and to make an uneven pattern on the decorative veneer with a roller. Since the process is mainly performed by hand, there is a problem that it is difficult to make the quality of the floor pillar constant by changing the taste of the unevenness depending on the operator who presses the roller.

The present invention has been proposed in view of the above circumstances, and an object thereof is to engrave an uneven pattern on a semifinished product for a floor pillar, which is formed by winding a decorative veneer around the outer periphery of a cylindrical core material. It is an object of the present invention to provide a concavo-convex pattern engraving device for manufacturing a floor pillar, which can mechanize the process, improve the quality of the floor pillar, and improve the workability of the engraving work.

[0006]

In order to achieve the above object, the present invention provides a semifinished product for floor pillars, which is obtained by winding a decorative veneer on the outer surface of a cylindrical core material made of laminated wood, and a natural wood grain. A device for engraving a concave-convex pattern similar to that of a work table for supporting the semi-finished product for the floor pillar so that the semi-finished product can be moved in the axial direction of the semi-finished product for the floor pillar, and bites on the end surface of the semi-finished product for the floor pillar. A holding mechanism for holding the semi-finished lever product in a lying state, a rotation mechanism for rotating the semi-finished product for floor pillar in the circumferential direction thereof, a support slider for supporting each of the holding mechanism and the rotation mechanism, and this support slider. A moving mechanism for reciprocating along the axial direction of the semi-finished product, and a semi-finished product provided in the middle of the moving path of the semi-finished product for the floor pillar and pressing the semi-finished product from both sides thereof to form an uneven pattern on the outer surface of the semi-finished product Left and right pair of pressure rollers It is made of comprises a.

[0007]

In order to give the semi-finished product for floor pillars an uneven pattern by the apparatus of the present invention, the semi-finished product for floor pillars is placed on the work table, and after the end face of the semi-finished product is bitten by the holding mechanism, the pressure roller is pressed. The semi-finished product is moved in the axial direction by rotating the pressing roller while passing the semi-finished product therebetween. By this operation, a concavo-convex pattern by the pressing roller is engraved on the contact surface of the semi-finished product with the pressing roller.

If a concave-convex pattern is engraved on a part of the outer peripheral surface of the semi-finished product by one operation, the semi-finished product for floor pillars is rotated in the circumferential direction by the rotating mechanism to change the position of the semi-finished product and then again. By passing the semi-finished product between the pressure rollers and engraving the uneven pattern on the other parts as well, finally, the uneven pattern is engraved on the entire circumference of the semi-finished product for floor pillars, and the floor pillars are finished. As finished.
