Description

[Detailed explanation of the idea] This invention relates to a guide device for a woodworking selvedge processing machine.

Generally, when a veneer is attached as a decorative veneer to the surface of a material, the width of the veneer is made larger than the width of the material, and when it is attached, the outside of the veneer protrudes from the material to form ears.

The selvage processing machine is used for the purpose of cutting and removing this selvage, and its structure is such that the surface of the veneer is placed parallel to the table surface, and the material is moved along the table surface. However, the tab is configured to be cut and removed using a rotary cutter having an axis perpendicular to the table surface.

However, the thickness of the veneer is usually 11rrIrL~2
rrrm, and due to the vibration during cutting by the brittle cutter that rotates at high speed, cracks in the ears propagate to the parts attached to the material, resulting in a deterioration in the quality of the products.

The purpose of this invention is to attach it to the above-mentioned selvedge processing machine,
An object of the present invention is to provide a guide device that prevents cracks from occurring in the ears during cutting with a cutter.

The gist of the structure of this invention is to arrange a guide plate as close as possible to the cutter in the above-mentioned selvedge processing machine on the entry side of the material to hold the selvage part in a non-vibrating state from both the front and back sides. It is.

The structure of this invention will be explained below with reference to the illustrated embodiment.

In FIG. 1, a circular notch 2 is carved on the rear side of a horizontal table 1, a rotary cutter 3 is provided concentrically with this notch 2, and the axis of the rotary cutter 3 is set on the surface of the table 1. The rotary cutter 3 is perpendicular to the surface of the table 1, is rotatably supported by a bearing (not shown) fixed to the table 1, and is configured to rotate at high speed in the direction of arrow A by a drive mechanism (not shown), and the lower end of the rotary cutter 3 is positioned at a predetermined distance from the surface of the table 1. It is at the bottom of the dimension.

Reference numeral 4 denotes a lower guide plate, which is vertically installed on a bracket 5 fixed to the rear side of the table 1. Its front end is located slightly behind the front surface of the rotary cutter 3, and has a predetermined space between it and the surface of the table 1. It is formed so that there is an interval of .

Furthermore, the lower guide plate 4 is arranged as close to the rotary cutter 3 as possible.

Reference numerals 6 and 7 indicate an upper first guide plate and an upper second guide plate, both of which are located directly above the lower guide plate 4 and are both fixed to the bracket 5, with a predetermined vertical gap between the two guide plates. It is formed as such.

The height of these guide plates 6 and 7 from the surface of the table 1 is the upper edge a of the workpiece W placed on the table 1.
and the guide plate 6 and the guide plate 7.

Note that the workpiece W has a thickness of 1 mm or more on both the upper and lower surfaces of the raw material.
2TIr! Then, veneer boards C and d, each having a width wider than the material by a predetermined dimension, are attached to form an upper ear part a and a lower ear part e.

Furthermore, the gap between the lower guide plate 4 and the surface of the table 1 and the gap between the upper first guide plate 6 and the upper second guide plate 7 are defined to be slightly larger than the thickness of the ears e and a. There is.

Next, the usage and operation of the device of this invention will be explained.

As shown in FIG. 1, when the workpiece W is moved in the direction of arrow B along the surface of the table 1 with the side surface of the workpiece in contact with the circumscribed circle of the rotary cutter 3, the rotary cutter 3 cuts the upper edge of the workpiece W. The portion a and the lower ear portion e are cut and removed so as to be flush with the rear side surface of the material.

On the other hand, the ears a and e to be cut are held between the first upper guide plate 5 and the second upper guide plate 6 and between the lower guide plate 4 and the table 1 at a position immediately before entering the cutter 3. Therefore, even when the rotary cutter 3 is cutting the ears, the ears a and e do not vibrate, and therefore no cracks occur.

According to this invention, as described above, the ears are held between the guide plates or between the guide plates and the table at a position immediately before entering the rotary cutter, so that the ears can be held even by the cutting action of the rotary cutter. does not vibrate and therefore does not crack, resulting in a product of good quality.
