Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an end face processing machine for cutting, for example, the ridge of a furniture board.

(Prior art) As shown in FIG. 6, as a board material for furniture, there is a board material 1 in which both sides of the end face of a board main body 2 are formed into an arc shape, and a decorative board 3 is fixed to this end face. .

In this case, the ridge 1a of the board 1 is aligned so that the peripheral edge 3a of the decorative board 3 is along the peripheral edge 2a of the butt end surface of the board main body 2.
It is necessary to perform finishing processing, that is, edge processing.

A conventional end face processing machine for this has been shown in Fig. 4.

That is, the machine base 5 supports an X-axis movable table 6 that is moved in the X-axis direction by an X-axis motor 6a, and this X-axis movable table 6 supports a Z-axis sill 7 that is moved up and down by a Z-axis motor 7a. .

A cutter motor 8 is attached to the Z-axis sill 7 facing in the Y-axis (left and right) direction, and a cone-shaped cutter 9 is attached to the main shaft of the cutter motor 8 so as to protrude leftward.

In addition, the support stand 10 is attached to the machine stand 5 on the X-axis movable stand 6.
This support stand 10 is placed on the left side and fixed in an upright position.
The plate material 1 is extended in the X-axis direction and placed, and the ridge portion 1a, for example, the lower ridge portion, is placed on the cutter 9.
The blade 9a is arranged so as to be in contact with the blade 9a, and is fixed to the support stand 10 with a clamp 12.

Then, start the cutter motor 8 and drive the cutter 9.
While rotating, the X-axis motor 6a and the Z-axis motor 7a are controlled so that the cutter 9 moves on an annular trajectory line 11 along the ridge 1a of the plate material 1, as shown in FIG. , moves the cutter motor 8 in the X-axis and Z-axis directions.

(Problems to be Solved by the Invention) In the conventional method described above, the plate material 1 is fixed and the processing axis (cutter 9) is moved.
Every time the length of the plate material 1 in the X-axis direction changes, it is necessary to change and adjust the amount of movement of the processing axis in the X-axis direction.
There was a drawback that the adjustment work was troublesome.

Furthermore, if the mounting accuracy of the plate material 1 or the flatness accuracy of the plate material is reduced, there is a drawback that the amount of cutting becomes uniform.

Furthermore, the amount of movement of the machining axis in the X-axis direction is limited by the size of the processing machine, and there is a drawback that end faces of plate materials that are long in the X-axis direction cannot be machined.

The object of the present invention is to obtain a novel plate material end face processing machine that eliminates the above-mentioned drawbacks.

It is adjusted by the shaft screw 26a.

As shown in FIG.
The shaft relay 28 is supported slidably in the Y-axis direction, and a spring 28a supports one side in the Y-axis direction, that is, the plate material 2.
Pressurizes in 3 directions.

Further, an end face copying roller 29 rotatable about the Z axis is attached to the upper part of the Y-axis relay 28, and the left end of the end face copying roller 29 is brought into contact with the end face 23a of the plate material 23, as shown in FIG.

When the end detector 35 is turned off due to the right movement of the plate material 23, the conveyor motor 19 is stopped to stop the right movement of the plate material 23, and then the rotation motor 27a is turned off.
is rotated to further rotate the swivel table 27 by 180 degrees to the left. As a result, the cutter 33 turns downward from the top to the left along the ridge 24c at the left end of the plate material 23, cutting the ridge 24c.

When the rotation of the turning table 27 is completed, the conveyor motor 19 is reversely rotated (rotated to the left), and the plate material 23 is moved in the opposite direction of arrow A (to the left), and the cutter 33 comes into contact with the lower ridge 24b and cuts this part. Cut. Then, as the plate material 23 moves to the left, the start end detector 34 is turned off, thereby completing the entire machining of the edge 24.

The conveyor motor 19 continues to rotate counterclockwise, and the plate material 23 is discharged to the input side.

On the other hand, the swivel base 27 rotates 360 degrees to the right (reverse rotation).
and return to its original position.

Incidentally, by using a fluid rotation joint in the shaft portion of the swivel table, the swivel table 27 may be of a type that does not rotate 360 degrees in reverse. Further, the sheet material may be discharged to the right by rotating the conveyor 19 clockwise.

Then, the right end of the next plate material 23 is the starting end detector 34.
When the conveyor motor 19 is turned on and the conveyor motor 19 is turned on, the swivel base 27 is rotated 180 degrees to the left via the swivel motor 27a, and the cutter 33 is turned on.
The ridge 24a at the right end of the plate material 23 is cut.

The end face of the plate material 23 is processed by sequentially repeating the above operations.

(Effects of the Invention) As is clear from the above description, in the present invention, the ridges at both ends of the plate allow the cutter to rotate along the edges of the plate, and the ridges in the longitudinal direction of the plate move the plate. Therefore, even a small processing machine can easily process a long plate material.

In addition, the copying roller that rolls along the edge and circumferential surface of the plate material allows machining while positioning the cutter, so even if the mounting accuracy and planar accuracy of the plate material are uneven, high-precision end face machining is possible. It has the effect of
