is cut into multiple square pieces.

The rotary cutting unit A and the rotary cutting unit B are driven by a motor and have a handle (not shown).
This makes it possible to adjust the vertical position (adjust the amount of scraping of the material 30).

The saw unit C is rotated by a motor 17 via a belt 18, and has a plurality of circular saw blades 19, 1 provided at predetermined intervals (the width of the square material to be made).
It has 9...

Further, dust collection channels 25, 25 are provided in the main body 2 for discharging shavings or chips from the rotary cutting unit A and the saw unit C.

Next, a feeding device D is provided above the surface plate 3 formed on the upper surface of the main body 2.

This feeding device D includes two roller cases 12,
12, each of the roller cases 12, 12 is provided with rollers 4, 4... as a means for contacting the material 30 and continuously feeding it,
Each of these rollers 4, 4... is connected to a shaft 7, 7 (joined by a coupling 10) via a shaft 5 and gears 6, 6.

The shafts 7, 7 are driven by a motor 9 via a belt 8.

On the other hand, the roller cases 12, 12 are connected to the motor 1
5, the rollers 4, 4, .

That is, the roller cases 12, 12 are moved up and down by the rotation of the motor 15 by a rack and pinion mechanism driven via the chain 14 and the width 13.

A saw unit C is installed in the roller cases 12, 12.
In order to prevent the risk of the cut ends of the material 30 returning, return stops 20, 20 are provided which project elastically downward (into the path of the material 30) and can be opened with handles 21, 21.

Next, the surface plate 3 is provided with rollers 23, 23, . . . for smoothly moving the material 30 fed by the rollers 4, 4, .

The operation of the automatic planer saw of the present invention having the above configuration will be explained next.

First, the roller case 1 is
2 and 12 are moved up and down to position the rollers 4, 4, . . . in accordance with the thickness of the material 30 and the amount of scraping.

Further, the rotary cutting unit A and the rotary cutting unit B are moved up and down by the handles to position them in accordance with the amount of scraping of the upper and lower surfaces of the material 30.

Further, the circular saw blades 19, 19, . . . of the saw unit C are adjusted in accordance with the width of the square material to be made.

After the above preparations, the rotary cutting unit A, the rotary cutting unit B, and the saw unit C are driven.

At the same time, the motor 9 drives the rollers 4,
4... is rotated.

Next, the plate-shaped material 30 is fed from the right side in FIGS. 1 and 2 to rollers 4, 4, whose vertical positions are adjusted according to the thickness of the material 30 and the amount of scraping.

As a result, the material 30 is sent to the rollers 4, 4, .

That is, the material 30 shown in FIG. 3 is in the state shown in FIG. 4.

Next, the material 30 reaches the rotary cutting unit B at the rear, where the upper surface is cut to a predetermined thickness t as shown in FIG.

In this state, the material 30 is continuously sent to the saw unit C by the rollers 4, 4, . . . of the roller case 12.
The vertical position of the material 30 is adjusted according to the thickness of the material 30 and the amount of scraping, so the material 30 is
It will be sent with sufficient force from...

In other words, the upper and lower surfaces are cut by the rotary cutting units A and B, and not only are the surfaces made flat, but also the rollers 4, 4, etc. of the roller case 12, whose vertical positions are adjusted taking into account the amount of cutting, are sent to the saw unit C. , the roller 4 of the material 30,
4... is carried out extremely reliably and smoothly.

The material 30 sent by the rollers 4, 4...
As shown in FIG. 6, the plurality of circular saw blades 19, 19... of the saw unit C cut a plurality of square pieces 3 of a predetermined width W.
1, 31...

When the material 30 is fed by the rollers 4, 4...
It passes through the return stoppers 20, 20 provided on the roller cases 12, 12 (they are pushed upward because they protrude elastically).

The return stoppers 20, 20 return after the material 30 has passed and project downward.

As a result, the material 30 is cut as shown in FIG. 6, and scraps 32, 32 are generated at both ends, and even if the feed of the rollers 4, 4 is not sufficiently transmitted, the scraps 32, 32 are not returned to the return stoppers 20, 20.
This is prevented by

The automatic plane saw machine of the present invention may have the following configuration other than the embodiment shown above.

That is, the feeding device D is not limited to the rollers 4, 4, etc. as in the above embodiment, but also has an endless track having a plurality of narrow flat plates attached adjacent to each other on an endlessly suspended chain, and has a high coefficient of friction. It is also possible to replace the belt with a known feeding means such as an elastic belt that is elastically suspended endlessly.

Further, in particular, regarding the rollers 4, 4, etc. located at the upper part of the rotary cutting unit A, a known biasing member such as a spring or an air cylinder is interposed.
In some cases, the material 30 is fed while being pressed against the three surfaces of the surface plate.

If this biasing member is installed on the roller case 12 on the near side, the roller case 12 on the near side will slightly press the two roller cases 12, 12 making up the feeding device D and the rotary cutting unit B on the upper part. It is sufficient to adjust the vertical position of the material 30 integrally so that the desired product thickness is obtained, without simply adjusting each of them so that the desired thickness of the material 30 is obtained.

Furthermore, if the rotary cutting unit A is also vertically adjustable, if the plane blade protrudes upward from the rear surface plate, when the material 30 after cutting is pressed by the upper roller 4, the plane blade will If the lower part of the material 30 is cut too much, resulting in a partial dent, or conversely, if the plane blade is located below the rear surface plate, the front part of the material 30 will be cut off by the rear part during cutting. This eliminates the inconvenience that when the material collides with the front surface of the surface plate or rides on the corner of the front surface while being fed, the material is cut into a tapered shape with respect to the desired uniform cutting thickness, resulting in thickness errors. Become.

Of course, this adjustment range over the top and bottom of the plane blade is minute and depends on the wear of the plane blade, so this can be resolved by carefully adjusting the blade length.

A similar effect can be obtained if the rotary cutting unit A is made vertically adjustable.

Furthermore, although two return stoppers 20, 20 are provided in the roller cases 12, 12 in the above embodiment, the present invention is not limited to this, and for example,
They may be provided as long as they can elastically protrude into the course of the material 30, such as provided in the following table, and the number is not limited to two.
