Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traveling machining board, and more particularly to a traveling circular saw machine called a running saw or a panel saw.

[0002]

2. Description of the Related Art In the plastic processing industry and the furniture manufacturing industry, a running circular saw machine called a running saw or a panel saw is used for cutting or grooving a long plate-shaped processing material. The difference between a running saw and a panel saw lies in the running direction of the circular saw, which holds the work material horizontally (or almost horizontally) and runs the circular saw horizontally for processing (ie the cutting or grooving direction is The running saw is horizontal. On the other hand, the panel saw holds the work material vertically (or almost vertically),
The circular saw is adapted to run vertically for machining (ie the cutting or grooving direction will be vertical).

FIG. 3 is a perspective view of a general panel saw viewed from the plate-shaped processed material W side. A horizontal ruler plate 2 is horizontally arranged below the table 1 which is fixed and held substantially vertically. Further, a positioning ruler 2 for the processed material W is provided on the side of the table 1. Further, a circular saw traveling slit 4 is provided in the vertical direction at the center of the table 1. A circular saw 6 as a workpiece projects from the circular saw traveling slit 4 and travels along the circular saw traveling slit 4. A pressing plate 6 for the processed material W is arranged above the circular saw traveling slit 4 on the front surface side (the processed material W side) of the table 1.

In order to cut or groove the processed material W with this panel saw, first, the processed material W is supplied onto the horizontal ruler plate 2. Next, the horizontal ruler plate 2 and the processed material W are integrally moved and moved in the horizontal direction, and one end of the processed material W is set in contact with the positioning ruler 3. Here, the positioning ruler 3 is fixed at a desired position in advance. Subsequently, the processed material W set by the horizontal ruler plate 2 and the positioning ruler 3 is
The press plate 6 is pressed and fixed to the table 1. Then, the circular saw 6 is protruded from the circular saw traveling slit 4 by a desired amount and is caused to travel along the circular saw traveling slit 4, whereby the workpiece W is machined in the vertical direction. Here, when the protruding amount of the circular saw 5 on the surface of the table 1 is smaller than the thickness of the processed material W, the groove engraving process is performed, and when the protruding amount is large, the cutting process is performed.

FIG. 4 is a partially transverse plan view of FIG. The circular saw 5 is attached to a rotary shaft 7 of a motor (not shown) via a flange 8, and the circular saw traveling slit 4 is provided.
It is arranged so as to correspond to. Circular saw traveling slit 4 on the back side of the table 1 (on the side opposite to the processed material W)
Frame members 9 are attached to both sides of the frame member 9. The frame material 9 has an angled shape and has a structure in which the flange 9a is erected on the table 1. Therefore, the frame material 9 has a function of giving strength to the table 1 and holding it in a planar shape. On the other hand, a frame 6a having a U-shaped cross section is attached to the holding plate 6 to give strength to the holding plate 6 and prevent its deformation.

[0006]

By the way, in the large panel saw, the length of the circular saw traveling slit 4 (that is, the length of the processed material W) is 4 m or more, and the weight of the processed material W is several hundreds. May be kg. As described above, in order to process the large and heavy processed material W, it is necessary to increase the pressing force of the pressing plate 6. Then, on the table 1, the processed material W
A large force is applied due to the addition of the weight and the pressing of the pressing plate 6. As a result, the table 1 is bent in the longitudinal direction (that is, the traveling direction of the circular saw 5). Since the deflection of the table 1 is complicated, the projection amount of the circular saw 5 on the surface of the table 1 varies and the table 1
The angle formed by the circular saw 5 and the circular saw 5 varies. Therefore, in the case of grooving, the depth and angle of the formed groove change, and in the case of cutting, the angle of the cut surface changes.

As described above, in the panel saw, there is a problem that the working accuracy is lowered due to the deflection of the table 1. In order to solve this problem, the rigidity of the table 1 should be increased. To this end, the table 1 should be thickened,
The flange 9a of the frame material 9 may be raised. However, in that case, the amount of protrusion of the circular saw 5 on the surface of the table 1 becomes small, the depth of the groove is limited, and the thickness of the workpiece W that can be cut is limited.

Therefore, in order to solve these problems,
A device disclosed in Japanese Patent Laid-Open No. 4-163101 has been proposed. In this device, mounting frames are integrally connected to the table on both sides of the circular saw traveling slit on the back surface side of the table. Then, parallel rails are respectively arranged on the mounting frame, and a moving base for holding a circular saw is movably arranged on the pair of parallel rails.

As a result, the following effects are said to be obtained. 1) The rigidity of the mounting frame is added to the rigidity of the table, and the deflection of the table can be reduced.

2) Even when the table is bent, the table and the rail are displaced together, so that the protrusion amount of the circular saw on the surface of the table does not change. 3) By disposing the mounting frames on both sides of the circular saw traveling slit, the strength of the tables on both sides of the circular saw traveling slit becomes uniform, and steps are prevented from occurring on the tables on both sides of the circular saw traveling slit. You can

However, in this device, as shown in FIG.
As shown in FIG. 5, the mounting frame 10 cannot be provided in the vicinity of the circular saw traveling slit 4 in order to avoid the rotary shaft 7 and the flange 8. Especially, since the mounting frame (not shown) on the motor 11 side must avoid the motor 11,
It can be provided only at a position separated from the circular saw traveling slit 4 by the size of the motor 11.

Therefore, it is not possible to sufficiently increase the rigidity of the table 1 in the vicinity of the circular saw traveling slit 4 which is the most important. Further, the table 1 and the rail (that is, a mounting frame (not shown)) near the circular saw traveling slit 4
But they don't completely move together. Furthermore, the strength of the table 1 on both sides of the circular saw traveling slit 4 cannot be made completely uniform.

For example, as shown in FIG. 5, in the case where the end face of the processed material W is cut off by makeup, with respect to the table 1a on the side on which the processed material W is pressed by the holding plate 6, a force (arrow) directed toward the back surface side. While the A direction) works, no force works on the table 14 on the side without the processed material W. Therefore, the table 1a on the side having the processed material W is deflected, whereas the table 14 on the side without the processed material W is not deflected, and steps are formed on the tables 1a and 1b on both sides of the circular saw traveling slit 4.
Then, the circular saw 5 does not hit the processed material W vertically, and the precision of the makeup cutting becomes low.

Therefore, there is a drawback that the above-mentioned action cannot be sufficiently exhibited and the processing accuracy cannot be sufficiently enhanced. The present invention has been made to solve the above problems, and an object thereof is to provide a highly accurate traveling processing board with a simple configuration.

[0015]

In order to solve the above-mentioned problems, the present invention presses and fixes a processed material on the surface side of a table by a pressing plate, and the processed material is passed through a slit provided in the table to the surface of the table. The gist of the present invention is to provide a traveling processing board that is processed by a workpiece that projects upward and travels along a slit and that includes a pressing member that presses the table near the slit from the back surface side of the table with an appropriate pressure.

[0016]

Therefore, according to the present invention, even when the table is bent by the weight of the processed material and the pressing of the pressing plate, the pressing force of the pressing member is appropriately set so that the force and the pressing force for bending the table can be reduced. The pressing force of the members is balanced to correct the deflection of the table. Therefore, the table can be accurately held in a flat shape, and the processing accuracy of the processed material can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is embodied in a panel saw will be described below with reference to FIGS. In this embodiment, the same components as those in the conventional example shown in FIGS. 3 to 5 are designated by the same reference numerals and detailed description thereof will be omitted.

FIG. 1 is a cross-sectional plan view of the panel saw of this embodiment. 2 is a partial vertical plan view of FIG. On the back surface side of the table 1, a pair of left and right mounting frames 10a and 10b are attached in parallel with the slit 4 for running the circular saw. A pair of left and right parallel rails 12a and 12b are disposed on the back sides of the two mounting frames 10a and 10b.

Both vertical frames 13 of the moving base 13 having a substantially rectangular shape.
Sliding cylinders (slide bearings) 14a and 14b are provided on a and 13b, respectively. Each sliding cylinder 1
4a and 14 engage with the parallel rails 12a and 12b, respectively, and are provided slidably with respect to the parallel rails 12a and 12b.

On one horizontal frame 13c of the moving base 13,
A horizontal support shaft 16 is provided via a mounting metal 15. A rotary plate 17 is rotatably attached to the horizontal support shaft 16, and the motor 11 is fixed to the rotary plate 17. The horizontal support shaft 16 and the rotation shaft 7 of the motor 11 are parallel to each other.

The moving base 13 is provided with a pneumatic cylinder 18, and the piston rod 18a of the pneumatic cylinder 18 is connected to the rotating plate 17. Therefore, when the piston rod 18a is extended, the rotating plate 17 rotates in the direction of the table 1, and the circular saw 5 moves along with the table 1.
On the surface of the. On the contrary, when the pinnetton rod 18a contracts, the rotating plate 17 rotates in the direction opposite to the table 1, and the circular saw 5 is retracted into the back surface of the table 1 accordingly.

Chains 19 are hung on both lateral frames 13c and 13d of the moving base 13, respectively. And
Each chain 19 is wound or unwound by a traveling motor (not shown), so that the moving base 13 moves the parallel rails 1312a. The vehicle travels in the direction 12b (that is, the vertical direction).

Here, the moving direction of the moving base 13, that is, the circular saw 5 at the time of processing the work W is the direction of arrow B shown in FIG. Each pressing member 20 is attached to the moving base 13 on the moving direction side of the circular saw 5 when the work W is processed. A compression coil spring is inserted in the pressing member 20, and the compression coil spring urges a roller 20 a provided at the tip of the pressing member 20. The roller 20a is rotatable in the moving direction of the circular saw 5. Further, the rollers 20a of the pressing members 20 are arranged so as to contact the frame members 9 in the vicinity of the circular saw 5 and the circular saw traveling slit 4, respectively. for that reason,
The pressing member 20 (more precisely, the roller 20a of the pressing member 20) presses the table 1 through the frame material 9 toward the front surface side (working material W side) with a constant pressure.

If the pressing force of the pressing member 20 is appropriately set, even if the table 1 is bent, the pressing member 20 is deformed.
With respect to the portion pressed by, the force of the weight of the processed material W and the force of the pressing plate 6 (that is, the force that bends the table 1) and the pressing of the pressing member 20 can be balanced. As a result, the bending of the table 1 is corrected at the portion pressed by the pressing member 20.

Therefore, no matter how complicatedly the entire table 1 is bent, the amount of protrusion of the circular saw 5 on the surface of the table 1 is constant and does not change, and the angle formed by the table 1 and the circular saw 5 is always constant. It is constant and does not change. Therefore, the processing accuracy can be improved regardless of the deflection of the table 1.
That is, since the deflection of the table 1 does not affect the processing accuracy, it is not necessary to excessively increase the rigidity of the table 1, and the table 1 is made thin and the flange 9 of the frame material 9 is provided.
It is possible to lower a. As a result, it is possible to reduce restrictions on the depth of grooving and the thickness of the workpiece W that can be cut.

Further, by uniformly pressing the tables 1 on both sides of the circular saw traveling slit 4 by the respective pressing members 20, the deflection of the table 1 is evenly corrected, so that both sides of the circular saw traveling slit 4 are corrected. It is possible to prevent a step from being formed on the table 1.

As described above, in this embodiment, by simply providing each pressing member 20 in the conventional example, the deflection of the table 1 is corrected without increasing the rigidity of the table 1, and a high processing accuracy is actually achieved. can do.

Since the roller 20a is provided at the pressing portion of each pressing member 20, the frame material 9 is scratched by sliding as the circular saw 5 travels, and the pressing portion of the pressing member 20 is pressed. Can be prevented from wearing. However, the position of the table 1 pressed by each pressing member 20 needs to be as close as possible to the processing portion of the processing material W by the circular saw 5.

The present invention is not limited to the above embodiment, but may be carried out as follows. 1) The frame material 9 is omitted.

2) The pressing member 20 is embodied not by a compression coil spring but by a member that generates a pressing force such as an air spring, a rubber spring, or a hydraulic spring. 3) The roller a provided at the tip of the pressing member 20 is omitted, and instead, the pressing member 2 is made of a material having a small friction coefficient such as Teflon.
Form a zero tip.

4) A plurality of pressing members 20 are provided instead of two, and a plurality of positions of the frame material 9 are pressed. 5) A plurality of pressing members 20 are provided, and a circular saw traveling slit 4 is provided.
A plurality of points on the table 1 on both sides of the table 1 are pressed along the direction. Here, the pressing member 20 is fixed not to the moving table 13 but to the mounting frame 10a. This corrects not only a predetermined portion of the table 1 but also the deflection of the entire vicinity of the circular saw traveling slit 4 of the table 1.

6) The pressing member 20 does not press the table 1 at a constant pressure, but a detection member for detecting the deflection of the table 1 is provided, and an appropriate pressure is generated according to the detected deflection. The table 1 is pressed by.

7) Perform the same in a running saw instead of a panel saw. 8) The same operation is performed not only on the traveling circular sawing machine but also on other traveling processing boards such as a traveling jigsaw machine and a traveling router board.

[0034]

As described above in detail, according to the present invention, there is an excellent effect that a highly accurate traveling processing board can be provided with a simple structure.
