Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-sided plane which is capable of simultaneously cutting and finishing an upper surface and a lower surface of a material to be carried in.

[0002]

2. Description of the Related Art In general, a plane is a rotating horizontal plane (a blade barrel which is rotatably arranged in a horizontal direction, and one or more plane blades are embedded around the barrel so that the plane can be retracted. (Hereinafter, simply referred to as a rotary blade) and a table that moves up and down.

Therefore, in this tool, the cutting amount of the material to be carried in can be adjusted by adjusting and setting the relative height of the table with respect to the rotary blade whose height position is fixed.

By providing two upper and lower rotary blades in parallel and allowing the upper rotary blade to move up and down, it is possible to form a two-sided plane which simultaneously finishes the upper surface and the lower surface of the material to be carried in. .

[0005]

According to the prior art, the table is moved up and down in order to determine the amount of cutting on the lower surface, so it can be used in combination with a sawing machine or the like for cutting in the previous step. There was the problem of being extremely difficult. The material discharged from the saw machine is
If the height of the table of the following plane is not fixed to adjust the cutting amount, and the height of the table is not fixed, and the material from the saw cannot be carried in smoothly. This can happen.

Therefore, an object of the present invention is to provide a two-sided plane which can be connected to a saw machine or the like in the previous step without any trouble by dividing the table for carrying in the material into a fixed table and a lower movable frame. To do.

[0007]

The structure of the present invention for achieving the above object is a fixed table arranged at a material carrying-in position and a lower movable frame arranged side by side with respect to the fixed table so as to be adjustable in height. And a fixed table and an upper movable frame that is arranged above the lower movable frame and can move up and down relative to the lower movable frame, a lower rotary blade mounted on the lower movable frame, and a lower rotary blade. The gist of the present invention is to include an upper rotary blade mounted on the upper movable frame.

The lower movable frame and the upper movable frame can be mounted on a front surface of a fixed frame provided with a fixed table so as to be vertically movable, and the both can be connected via a ball screw shaft.

A pair of receiving members are arranged on the left and right of the lower rotary blade, and the upstream receiving member is mounted on a fixed table.
The receiving member on the downstream side can be mounted on the lower movable frame.

Further, the receiving member on the upstream side can be moved back and forth in parallel with the lower rotary blade, and can be provided with a rear operation top plate and a front evacuation top plate lower than the operation top plate. .

A pair of depolarizing drive feed rollers are arranged on the left and right of the receiving member, the feed roller on the upstream side is mounted on the fixed table, and the feed roller on the downstream side is mounted on the lower movable frame. These feed rollers can be formed longer than the upper rotary blade and the lower rotary blade.

On the other hand, a pair of push members mounted on the upper movable frame may be disposed on the left and right of the upper rotary blade, and the upstream push member may be movable up and down. Alternatively, a pair of positively driven feed rollers mounted on the upper movable frame may be provided.

[0013]

According to the structure of the present invention, since the fixed table is located at the material loading position and has a fixed height, the material loading height is the same as that of the feed surface of the saw machine in the previous step. The material from the saw machine or the like can be smoothly carried in by adjusting the above. On the other hand, since the lower movable frame is equipped with a lower rotary blade and the height can be adjusted with respect to the fixed table, it is possible to adjust the cutting amount of the lower surface of the material by moving the lower movable frame up and down. it can.
Also, the upper movable frame equipped with the upper rotary blade can move up and down relative to the lower movable frame, so by adjusting the relative distance to the lower movable frame, the finishing height position of the upper surface of the material can be adjusted. It can be adjusted and set arbitrarily.

When the lower movable frame and the upper movable frame are mounted on the front surface of the fixed frame, the fixed frame can be formed as a common structure that supports the lower movable frame and the upper movable frame, and supports both. Therefore, since it is not necessary to provide a separate structure, the whole structure can be made the simplest.

By connecting the lower movable frame and the upper movable frame through the ball screw shaft, the ball screw shaft can be adjusted to a desired relative fine distance.

When the receiving members are arranged on the left and right of the lower rotary blade, each receiving member supports the lower surface of the material on the upstream side and the downstream side of the rotary blade. Therefore, the lower rotary blade is positioned by raising the lower movable frame so that it is higher than the receiving member on the upstream side by the amount corresponding to the cutting amount during cutting. Just set them at the same height.

When the receiving member on the upstream side can be moved back and forth, by retracting the whole rearward, the lower front retracting top plate can correspond to the lower rotary blade, and the lower rotary blade is not operated. In the above, it is possible to completely prevent the inconvenience that the carried-in material interferes with the receiving member.

By disposing depolarizing drive feed rollers on the left and right of the receiving member, the feed rollers can smoothly feed the material discharged from the sawing machine or the like. Further, if the feed roller is formed longer than the upper rotary blade and the lower rotary blade, only the product side of the material from the saw machine, etc., which is cut into a predetermined size, is made to correspond to the upper rotary blade and the lower rotary blade. On the other hand, the semi-finished product side does not correspond to the upper rotary blade and the lower rotary blade, and can be discharged to the downstream side without finishing and returned to the saw machine or the like in the previous process.

When the pressing members are arranged on the left and right of the upper rotary blade, each pressing member presses the upper surface of the material on the upstream side and the downstream side of the upper rotary blade to stabilize the material being cut. The upstream pressing member may be positioned slightly higher than the upper rotary blade during cutting, and the downstream pressing member may be set at the same height as the upper rotary blade.

By disposing positively driven feed rollers on the left and right of the pressing member, each feed roller can stably and positively feed the material being cut.

In addition, the pushing member 36 on the upstream side shortens the air cylinder 36d and retracts it upward from the lowermost portion of the outer periphery of the upper rotary blade 32 by a distance δ2. However, the distance δ2 corresponds to the maximum cutting amount of the upper surface of the material B obtained by the upper rotary blade 32.

After the respective parts of the double-sided plane are set in this way, the lower rotary blade 31, the upper rotary blade 32, and the positively driven feed rollers 38, 39 are rotated in a predetermined direction, and the material B is passed through the saw blade.
When the material B is loaded, the material B is lower rotary blade 31, upper rotary blade 32.
While the lower surface and the upper surface of the product side B1 corresponding to the above are cut at the same time, the semi-finished product side B2 can be discharged to the rear of the two-sided plane without cutting any surface. Product side B
1 is positively fed through the feed rollers 38, 39, and the lower surface and the upper surface are cut by the lower rotary blade 31 and the upper rotary blade 32.
This is because it can be directly discharged to the rear via 34. The semi-finished product side B2 discharged in this way

Further, by extending the air cylinder 36d and lowering the pressing member 36 on the upstream side below the upper rotary blade 32, the cutting of the upper surface of the product side B1 can be stopped. Further, the air cylinder 21b is shortened to lower the lower movable frame 21, and the lower rotary blade 31 is moved to the receiving member 3 on the upstream side.
If it is lower than 3, the lower surface of the product side B1 can be stopped.
