On the other hand, the cutting assembly 20 is further provided with a cutting motor 25.

Swing arm 40 is coupled to the front of the cutting assembly 20, one end is rotatably coupled to the cutting assembly 20, the other end is coupled to the cutting blade portion 40. In this case, a portion of the swing arm 40 coupled to the cutting assembly 20 is connected to the cutting motor 25, and the rotating shaft 25c of the cutting motor 25 extends to the inside of the swing arm 40. The driving gear 25a is coupled to the rotation shaft 25c inside the swing arm 40, and the driven gear 25b is installed near the opposite end of the swing arm 40 where the driving gear 25a is installed. The drive gear 25a and the driven gear 25b are connected by a motion transfer means 25d such as a belt or a chain, and the driven gear 25b is coupled to the cutting blade rotation shaft 41c. Therefore, when the cutting motor 25 rotates, power is transmitted through the drive gear 25a, the motion transmission means 25c, the driven gear 25b, and the cutting blade rotating shaft 41c, so that the cutting blade 41 rotates. You can do it.

On the other hand, the swing arm 40 itself is rotated by the swing arm rotary motor 27, the drive gear 27a, and the driven gear 27c. Swing arm rotary motor 27 is installed in the cutting assembly 20, the rotating shaft 27c of the swing arm rotary motor 27 extends toward the front end is coupled to the drive gear 27a. Then, a driven gear 27b is formed on the curved outer peripheral surface of the swing arm, so that the drive gear 27a and the driven gear 27b are constantly engaged. Accordingly, when the swing arm rotation motor 27 rotates, the drive gear 27a coupled to the coaxial rotates, and the driven arm 27b engaged therewith rotates, so that the swing arm 40 rotates.

Hereinafter, an operating state of the cutter device 100 according to the present invention will be described with reference to FIG. 6. 6 is a schematic plan view of the cutter apparatus 100 according to the present invention as viewed from the front (y direction).

In FIG. 6A, the guide frame moving motor 13 rotates in reverse to move the guide frame 10 along the longitudinal direction (x direction) to the left side in the drawing with respect to the reference frame 30. The state where one end of 10) is located at the outermost side of the left side (left end of the cutter movement range R) and the other end of the guide frame 10 is located on the reference frame 30 is shown.

At this time, the cutting assembly moving motor 23 also rotates in reverse, so that the cutter assembly 20 is located at the outermost side of the left side on the guide frame 10.

In addition, the swing arm rotation motor 27 is rotated so that the swing arm 40 is inclined at a predetermined angle with respect to the cutting assembly 20 to extend downward.

When the cutting motor 25 is rotated in this state, the cutting blade portion 41 rotates about the rotation shaft 41c at the outer end of the swing arm 40. That is, the cutting blade portion 41 rotates around the reference frame 30 at the outermost angle on the left side (ie, at the left end of the cutter movement range R).

At this time, when the swing arm rotation motor 27 rotates, the cutting blade portion 41 rotates about the rotation shaft 25c of the cutting motor at the outermost side of the left side with respect to the reference frame 30 and performs cutting operation. It can be done.

6 (b), in the state of FIG. 6 (a), as the cutting assembly moving motor 23 rotates forward, the cutting assembly 20 is moved from the left outermost position of the guide frame 10 to the right. Shown is the movement to the outermost position of.

In this state, when the cutting motor 25 is rotated, the cutting blade part 41 can be rotated in front of the reference frame 30 (that is, at the center of the cutter movement range R). In addition, when the swing arm rotation motor 27 rotates, the cutting blade part 41 may rotate while pivoting about the rotation shaft 25c of the cutting motor 25 in front of the reference frame 30. Will be.

6 (c) shows that the guide frame movement motor 13 rotates forward in the state of FIG. 6 (b) so that the guide frame 10 moves in the longitudinal direction (x direction) to the right in the drawing with respect to the reference frame 30. By moving along), one end of the guide frame 10 is located on the reference frame 30, and the other end of the guide frame 10 is located at the rightmost outermost (right end of the cutter movement range R). Status is displayed.

In this case, the cutting assembly moving motor 23 maintains the stop state, so that the cutter assembly 20 is positioned at the outermost side of the right side on the guide frame 10.

In addition, as the swing arm rotation motor 27 rotates, the swing arm 40 pivots with respect to the cutter assembly 20 by a predetermined angle, so that the outer end portion extends in the longitudinal direction with respect to the guide frame 10. The angle is inclined to extend upward.

In this state, as the cutter assembly 20 is located at the right end of the cutter movement range R, when the cutting motor 25 and the swing arm rotating motor 27 are rotated, the cutting blade part 41 causes the cutter. At the right end of the movement range R can be rotated while turning about the rotation axis (25c).

6 (d), in the state of FIG. 6 (a), as the cutting assembly moving motor 23 reversely rotates, the cutting assembly 20 is moved from the outermost position on the left side on the guide frame 10. The state of movement and reaching the outermost position on the right is shown.

In this state, when the cutting motor 25 and the swing arm rotation motor 27 are rotated, as in the state of FIG. It is possible to rotate while rotating the cutting blade portion 41).

 Accordingly, by selectively adjusting the reverse rotation, forward rotation and on / off of the guide frame moving motor 13, the cutting assembly moving motor 23, the cutting motor 25, and the swing arm rotating motor 27, The cutter assembly 20 and the cutting blade portion 41 can be positioned at a predetermined position on the cutter movement range R, and the cutting blade portion 41 can be rotated while pivoting at the position.

Accordingly, when the cutter device 100 according to the present invention is installed in heavy equipment, the cutting blade part 41 is reciprocating within the extended range (the cutter movement range R) in the longitudinal direction, and thus, Cutting operations can be carried out over a range.
