Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a woodworking processing board capable of simultaneously processing two or four surfaces orthogonal to each other of a rectangular column material for small articles.

[0002]

2. Description of the Related Art A twin circular saw machine equipped with two saw blades is known as a circular saw machine for woodworking.

This is one in which two saw blades are rotationally driven by one or two main shafts, and it is possible to grind two positions of the material at a time. Therefore, the thickness of the processed material by this is determined by the relative distance between the two saw blades.

[0004]

According to such a conventional technique, since the two saw blades are held vertically through a horizontally arranged main shaft, two saw blades facing each other at the same time. Even if it can be processed, there is a problem that it is impossible to simultaneously process two orthogonal surfaces. Further, in the conventional twin circular saw machine, since the blade for processing is a saw blade, only sawing can be performed on the sawing material, and no other processing can be performed.

Therefore, in view of the problems of the prior art, an object of the present invention is to provide a horizontal blade disposed on the base frame,
A combination of a vertical blade and a feed table is to provide a woodworking processing board capable of simultaneously processing two or four surfaces of a small material material which are orthogonal to each other.

[0006]

The structure of the present invention for achieving the above object is to provide a horizontally long base frame, a horizontal blade and a vertical blade arranged in the central portion of the base frame, and a horizontal blade on the upper surface of the base frame. The gist of the present invention is that it is movably mounted on the machine and is equipped with a feed table that clamps materials and supplies them to horizontal and vertical blades.

The feed table is composed of a lower table and an upper table for sandwiching materials, and both ends of the lower table and the upper table can be connected to each other via a link which is tilted up and down in the feeding direction.

Further, a conveyor belt for conveying the processed material can be attached downstream of the horizontal blade and the vertical blade, and the conveyor belt can be interlocked with the feed table. At this time, the conveyor belt can be connected to the feed table via a one-way clutch, and a pressing roller for pressing the processed material is provided above the conveyor belt on the downstream side of the horizontal blade and the vertical blade. It can be attached.

However, each of the horizontal blade and the vertical blade may be two horizontal saw blades and two vertical saw blades.

[0010]

According to the structure of the present invention, the feed table is provided with respect to the horizontal blade and the vertical blade in the central portion of the base frame.
Since we can supply materials, horizontal blades and vertical blades
It is possible to simultaneously machine two orthogonal surfaces of the material. This is because the horizontal blade and the vertical blade are arranged orthogonal to each other. As the horizontal blade and the vertical blade, in addition to a saw blade, a rotary plane blade, a rotary groove cutter, or the like can be used.

When the feed table is composed of the lower table and the upper table, the feed table is the lower table,
The material can be clamped by sandwiching it vertically through the upper table. At this time, since the link is tilted up and down in the feed direction, the feed table can be applied by applying force in the feed direction through the upper table. The material can be clamped more strongly. In this case, the upper table can be lightly opened upward by urging the upper table upward via a compression spring or the like.

If a conveyor belt interlocking with the feed table is provided on the downstream side of the horizontal blade and the vertical blade, the conveyor belt can convey the processed material in the feeding direction and discharge it. Further, at this time, if the conveyor belt and the feed table are connected via the one-way clutch, the conveyor belt is driven only when the feed table is moved in the feed direction, and when the feed table is moved in the return direction, the feed belt is conveyed. The belt can be stopped. Furthermore, if a pressing roller is attached downstream of the horizontal and vertical blades, the pressing roller presses the processed material to prevent the material from fluttering and to further ensure the transport operation by the conveyor belt. You can

When the horizontal blade and the vertical blade are each made up of two horizontal saw blades and two vertical saw blades, it is possible to grind four surfaces of the material at the same time. However, in this case, it is preferable that the horizontal saw blade and the vertical saw blade each have a relative distance between each two blades adjustable.

The pressing roller 51 is horizontally attached to the tip of the swing bracket 51a, and the swing bracket 51a is swingably attached to a bracket 15d protruding from the side surface of the motor base 15a. . Therefore, the pressing roller 51 can contact the upper surface of the conveyor belt 41 by its own weight and rotate in a depolarizing manner.

The operation of such a circular saw machine is as follows.

First, when the feed table 30 is moved to the right side of the base frame 10 (FIG. 1), the feed table 30
Can be located entirely to the right of the horizontal saw blades S1, S1. Therefore, in this state, the upper table 32 of the feed table 30 is opened upward (solid line in FIG. 5),
The material b is inserted into the space a between the lower table 31 and the upper table 32, the upper table 32 is closed, and the material W is clamped (two-dot chain line in the figure). At this time, the material W has its rear side end surface closely attached to the ruler plate 14 (FIG. 3).

Next, the handle 3 of the feed table 30
If the feed table 30 is moved to the left side via 3, 33 (the direction of arrow A in FIGS. 1 and 3, hereinafter referred to as the feed direction),
The material W is a horizontal saw blade S that is integrated with the feed table 30.
1, S1, vertical saw blades S2, S2 supplied, horizontal saw blade S
With 1, S1 and vertical saw blades S2, S2, it is possible to grind four surfaces at the same time. However, the horizontal saw blade S1,
It is assumed that S1 and the vertical saw blades S2 and S2 are arranged on the front surface of the ruler plate 14 so as to intersect a square (FIG. 2). In addition, horizontal saw blades S1 and S1, vertical saw blades S2,
S2 is set in advance to predetermined relative intervals d1 and d2, and is rotated in the directions of arrows Ks1 and Ks2 in FIG.

The thin chips below the lower horizontal saw blade S1 of the sawdust W are moved by the horizontal saw blade S1 as the sawdust W is moved in the feeding direction via the feed table 30.
After flowing on the upper surface of the guide plate 15b on the downstream side of S1, it can be discharged to the left side of the side frame 15 via the lower side of the guide plate 15c on the downstream side of the vertical saw blades S2, S2 (see FIG. 3). (Direction of arrow B). For this purpose, the guide plate 1
The left edge of 5b and the right edge of the guide plate 15c are, respectively,
It is formed on upward and downward slopes.

On the other hand, the processed material W1 is the guide plate 15
It is possible to slide on the upper surfaces of b and 15c, push up the pressing roller 51, advance to the upper surface of the conveyor belt 41, and convey to the discharge side by the conveyor belt 41 in synchronization with the feeding speed of the material W by the feed table 30. Yes (direction of arrow C in FIG. 3). The conveyor belt 41 includes the connecting piece 30b and the chain 1.
3, the intermediate shaft 43, the chain 42, the pulley 41a,
This is because it is connected to the sending table 30. However, at this time, the one-way clutch 43a is
The rotation of 3 (in the direction of arrow K2 in FIG. 3) is transmitted to the sprocket 42b of the chain 42.

In this way, the sending table 30
After feeding the material W through the, and processing the entire length of the material W, the feed table 30 is returned to the original position. However, in the returning process at this time, the conveyor belt 41 maintains the stopped state. When the feed table 30 is returned in the reverse direction, the one-way clutch 43a causes the rotation of the intermediate shaft 43 (the direction opposite to the arrow K2 direction in FIG. 3) to rotate the sprocket 4 of the chain 42.
This is because it is not transmitted to 2b. Sending table 3
When 0 returns to the original position, the upper table 32 is opened upward, the material W is re-contacted to the ruler plate 14, and the upper table 32
Is closed to clamp the material W, and thereafter, the same operation may be repeated.

In the above description, the size of the processed material W1 is determined by the relative distances d1 and d2 between the horizontal saw blades S1 and S1 and the vertical saw blades S2 and S2. Therefore, the horizontal saw blades S1 and S1 and the vertical saw blades S2 and S2 are attached to the spacers S1b and S1.
Instead of using b, S2b, S2b, the drive motor 21,
By connecting a rotary ball spline to the output shaft of 22, the relative distances d1 and d2 can be set steplessly.

Further, the horizontal saw blades S1 and S1 and the vertical saw blade S2
, S2, one may be attached to each of the drive motors 21 and 22. It is possible to simultaneously process two orthogonal surfaces instead of the four surfaces of the work material W.

In place of the horizontal saw blade S1 and the vertical saw blade S2, the drive motors 21 and 22 can be equipped with rotary cutting blades, rotary blade cutters and other arbitrary cutting blades. Further, at this time, the blades attached to the drive motors 21 and 22 may be of the same kind as long as they are arranged orthogonally to each other, or arbitrary different kinds of blades may be combined.
Therefore, the term "horizontal blade" and "vertical blade" in the present invention refer to one of arbitrary cutting blades arranged so as to be orthogonal to each other via the drive motors 21 and 22, respectively. The drive motors 21 and 22 may be arranged such that the former is on the upstream side and the latter is on the downstream side, but the arrangement order of the two is reversed.

Further, the feed table 30 includes the handle 3
Instead of manual feeding via 3, 33, automatic feeding may be possible via an appropriate drive mechanism such as a rack and pinion mechanism or a chain mechanism.

[0042]

As described above, according to the present invention, by combining the base frame, the horizontal blade, the vertical blade, and the feed table, the horizontal blade and the vertical blade are
It is possible to process 2 or 4 surfaces of material at right angles at the same time, and the feed table can clamp the material and supply it to horizontal and vertical blades. It has an excellent effect that it can be used for.
