Reference numerals 7, 7 denote horizontal ruler plates disposed below the left side table Aa and the right side table Ab. The horizontal ruler plates 7, 7 are divided into right and left sides, and a slight space is provided at the abutting portion. A ruler surface 7a on which the workpiece W is placed is formed on the upper surfaces of the horizontal ruler plates 7, 7.

Reference numeral 8 denotes a mounting stay projecting forward from the lower portion of the base frame 1. Reference numeral 9 denotes a column-shaped rail holder rotatably provided by a supporting shaft 10 provided at the tip of the mounting stay 8. Is perpendicular to the table surface, and its axis is set to coincide with the ruler surface 7a. The rail holder 9 is installed in parallel with the table surface at a predetermined interval.

Reference numeral 11 denotes an arc guide disposed on the upper end of the right side table Aa. Reference numeral 12 denotes a slide bearing provided on the rail holder 9 so as to engage with the arc guide 11. Reference numeral 13 denotes an arc disposed on the outer peripheral surface of the arc guide 11. The gear 14 has a drive motor with a speed reducer provided at the end of the rail holder 9. A pinion gear 15 is attached to the output shaft of the drive motor 14, and meshes with the arc gear 13.

Reference numeral 16 denotes a linear guide rail disposed on the rail holder 9 and a circular saw unit which travels on the guide rail 16 and is provided on the traveling base 17 which engages with the guide rail 16 and on the traveling base 17. Drive motor 18,
It is constituted by a circular saw 19 fixed to the output shaft of the drive motor 18. The traveling path of the circular saw 19 is set so as to intersect the axis of rotation of the rail holder 9. Reference numeral 20 denotes a circular saw 19 cover.

Reference numerals 21 and 22 denote a pair of sprockets 23 provided at the upper end and lower end of the rail holder 9. A chain extending in the direction of the guide rail stretched over the sprockets 22, 23. Join. The sprocket 21 at the upper end is connected to the rail holder 9.
Is attached to the output shaft of the drive motor 24 with a reduction gear attached to the upper end of the motor.

Reference numeral 25 denotes a beam-shaped pressing plate disposed in the same direction as the traveling direction of the circular saw 19. The pressing plate 25 is moved closer to the table surface by a pair of pneumatic cylinders 26, 26 linked to its ends. Move away. This pressing plate 25
When approaching, the workpiece W is pressed and clamped to the table surface.

Reference numerals 27, 27 denote connecting brackets protruding from the upper and lower ends of the rail holder 9 toward the table surface. Reference numeral 28 denotes a thin-sided cutting edge provided on the table surface with both ends fixed to the connecting brackets 27, 27. The holder 29 is a blade plate attached to the blade holder 28. The blade plate 29 is provided corresponding to the cutting edge a of the circular saw 19, and abuts on the back side of the workpiece W to support it. I do.

On the blade holder 28, there are formed pushing operation portions 30, 30 having a slope shape corresponding to the rolling surface of the idle roller 2. The blade plate 29 is replaceably provided with a resin plate having excellent wear resistance.

Reference numeral 31 denotes an operation switch panel disposed at an appropriate position on the front surface of the rail holder 9. Reference numeral 32 denotes a drive motor 14 having a speed reducer.
A switch 33 for rotating the rail holder 9 clockwise and rotating the rail holder 9 clockwise is also rotated in the opposite direction, and a switch 34 for rotating the rail holder 9 counterclockwise is a pulse encoder (not shown). This is a display device that detects the position of an object and converts it into a tilt angle and displays it.

In the traveling circular sawing machine configured as described above, when the switch 32 of the operation switch board 31 is operated, for example, the rail holder 9 is rotated clockwise. Since the rotation angle at this time is displayed on the display 34, the traveling movement angle of the circular saw 19 can be set as desired by performing an operation while watching the rotation angle.

At the time of the above rotation, the connecting fittings 27, 2
7, the blade holder 28 attached to the rail holder 9 is rotated in conjunction with the blade holder 29 to change its position while keeping the blade port plate 29 in the running direction of the circular saw 19. Also, at this time, the pushing operation portion 30 of the blade holder 28 comes into contact with the rolling surface of the idle roller 2 and presses it in the immersion direction, so that the angle adjustment can be performed without any trouble.

After setting the cutting angle as described above, the work material W is supplied onto the horizontal ruler plate 7, and the work material W is moved in the lateral direction to be positioned. Then, the pressing plate 25
Is operated to press and clamp the workpiece W to the table surface.
Since the blade plate 29 corresponds to the pressing plate 25, the cut portion of the workpiece W can be held in a pressed state.

In this clamped state, when the circular saw unit B is moved downward from the upper position, the workpiece W is cut by the circular saw 19. At this time, since the cutting edge a of the circular saw 19 faces the cutting edge plate 29, the processing can be performed smoothly.

In the above-described embodiment, the cutting device of the present invention is applied to a traveling circular saw machine in which the cutting position is changed by rotating the guide rail. It is needless to say that the present invention can be similarly applied to a traveling circular saw machine of a type in which the processing position is changed by laterally moving.

In one embodiment, the present invention is applied to a traveling circular sawing machine having a substantially vertical table surface. However, the present invention can be similarly applied to a traveling circular sawing machine (running saw) having a horizontal table surface. .

Further, in one embodiment, the table surface is constituted by idle rollers, but a plate member having a small coefficient of friction may be used. In the case of a running saw having a horizontal table surface, a configuration in which a pressurized air injection hole is provided on the contact surface of the plate member may be employed.

[0034]

As described above, according to the cutting device for a traveling circular sawing machine according to the present invention, even when the cutting position is changed due to the movement of the guide rail, the blade is adjusted in accordance with the position of the cutting edge of the circle. A mouth plate can be accommodated. Therefore, an excellent effect that the cutting process can be performed smoothly without damaging the table surface is exhibited.
