Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention belongs to the field of manufacturing specific wooden products, and is mainly used for finishing curved edges of shelf boards and the like.

(Prior art) Furniture panels, shelf boards, etc. have traditionally had edges formed into arc-shaped curved surfaces. It is formed by wrapping the surface plate around it. At this time, a comb pattern is applied to the inner surface of the surface plate of the part that is wrapped around the curved surface, but due to the tensile stress generated on the surface of the curved surface, it takes time for it to adapt to the curved surface of the core material, and when finished by hand. However, when the adhesive hardened, a gap formed between the curved surface molding of the core material and the surface plate, making it impossible to mass-produce products of a constant quality.

(!!Problems to be solved by Ming) In view of the above-mentioned circumstances, the present invention has a technical problem of providing a method and an apparatus for molding and finishing the curved surfaces of furniture panels, shelf boards, etc. in a constant manner and in mass production. shall be.

(Means for Solving the Problems) The present invention solves the above-mentioned problem, and the method of finishing the curved surface of a wooden product according to the first invention provides a method for finishing a curved surface of a core material in a wooden product having a shelf-like long edge with a curved surface of 10,000 degrees. The curved surface of the surface plate that is circumscribed by is supported from the outside with a receiver that fits the curved surface, and the core material is pressed against the receiver to tightly adhere the surface plate to the curved surface of the core material and finish the curved surface. The method is to do so.

・The device for finishing the curved surface of a wooden product according to the invention of No. 2 has a rectangular frame for shaping, and at the bottom of the rectangular frame, a receiver with an arc-shaped longitudinal section is installed horizontally between the left and right supports in a gutter-like manner so as to be deformable in response to external pressure. At the top of the frame, a pressure plate of the required length is suspended from the rods of multiple fluid pressure cylinders and placed horizontally so that it can rise and fall freely, and a predetermined opening is opened on the left and right sides to allow it to swing in a vertical plane. It is made up of a freely adjustable anti-falling arm P.

(The posture of the wooden product is maintained constant by the receiver and anti-falling arm, and the core material can be pressed against the surface board under certain conditions using power.

(Example) To specifically explain the present invention based on an example, FIG.
As shown in Fig. 2, the finisher [a (hereinafter referred to as the present device a) for finishing the curved surface of a wooden product has a vertical rectangular frame 1 and a receiving plate 2 made of rubber and having an arc-shaped longitudinal section at the bottom. is held horizontally between the left and right columns 4.41 by being sandwiched between the respective holding plates 6.3' from the top and bottom to the left and right in a gutter-like manner, and the frame 1
A pressure plate 5 of a required length is suspended from the rods 7 of a plurality of fluid pressure cylinders 6 and installed horizontally so that it can rise and fall freely, and the shoulder of the pressure plate 5 is a shelf board whose curved surface can be finished by the device a. The pressing plate 5 is locked to the end surface 10 of the core material 9 of the
1, and on the left and right sides of the frame 1, openings are opened just enough to insert the shelf boards 8, and anti-falling arms 12 that can swing freely in a vertical plane are arranged. There is. Therefore, when finishing the curved surface of the shelf board 8 with the core material 9 and the surface board 11 temporarily bonded with adhesive, the anti-falling arm 12 is rotated upward to open a predetermined width, and the curved surface of the shelf board 8 is finished. After inserting it into the receiving body 2, the anti-falling arm 12 is rotated to a horizontal position to support the surface of the top plate 11 and held vertically so as not to tilt toward the center of gravity. 6 is operated synchronously to lower the rod 7,
The pressing plate 5 integrated at the tip of the rod 7 is restrained by the end surface 10 of the core material 9 of the shelf board 8 and presses the core material 9 to a predetermined position, so that the comb-processed W613 of the surface plate 11 is tightly attached to the curved surface of the core material 9. to complete the complete curved surface finish.

(Effects of the Invention) As described above, according to the present invention, the curved surfaces of the core material and the surface plate are always closely bonded, so quality is constant, and curved surface finishing is simplified by power, so mass production is possible. effective.
