When the mounting table 110 is at the initial position, when the controller 510 outputs a driving control signal to the first linear drive source such as the second cylinder 210, the driving of the first linear drive source such as the second cylinder 210 is performed. When the mounting table 110 moves forward linearly in the longitudinal direction in which the first chainsaw 310 is located, and the mounting table 110 reaches the cutting position by the linear movement of the forward second position The detection sensor 230 detects this and outputs a detection signal to the control unit 510, and the control unit 510 which receives this outputs a stop control signal to a first linear driving source (eg, the second cylinder 210) and stops. The second cylinder 210 which receives the control signal stops the operation, and the mounting base 110 stops the linear movement of the forward by the operation stop of the second cylinder 210.

On the contrary, when the mounting table 110 is in the cutting position, when the controller 510 outputs the driving control signal to the second cylinder 210 which is the first linear driving source, the second cylinder 210 which is the first linear driving source is output. When the mounting base 110 moves linearly toward the initial position by the driving, and the mounting base 110 reaches the initial position by the linear movement of the retreating, the second position sensor 230 detects and detects this. Outputs a signal to the controller 510, and the controller 510 receiving the signal outputs a stop control signal to the second cylinder 210 as the first linear driving source, and the second cylinder 210 receiving the stop control signal The operation stops, and the mounting base 110 is stopped at the initial position by the stop of the second cylinder 210.

In addition, the second position sensor 230, the second initial position sensor 231 for detecting the initial position of the mounting table 110 and the second cutting position detection for detecting the cutting position of the mounting table 110. It may be configured as a sensor 232.

It may be configured as a sensor for detecting the position of the (110).

When the moving drive source pushes or pulls the rotating body 323, the first cutting module 300 may include a first return position in which the first chainsaw 310 is set (where the first return position is a first chainsaw ( As the initial position of 310, the first chainsaw 310 is a position returned from the mounting base 110 after cutting the runner 20] and the runner cutting position (where the runner cutting position is the first transmission). The saw 310 is the position of the first chainsaw 310 in which the runner 20 has been cut.], So that the saw chain can be operated only between the first return position and the first return position. The third position detection sensor 350 for outputting a detection signal to the control unit 510 when each reaches the runner cutting position is configured to further include.

In this case, when receiving the detection signal from the third position sensor 350, the control unit 510 outputs a stop control signal for stopping driving of the moving driving source to the moving driving source.

When the first chainsaw 310 is in the first return position, when the controller 510 outputs a driving control signal to the moving drive source (eg, the third cylinder 352), the moving drive source such as the third cylinder 352 is provided. In accordance with the rotation of the rotating body 323 by the driving of the first chainsaw 310 "rotates" in one direction while approaching the runner 20 to cut the runner 20, the cutting is completed, the first transmission When the saw 310 reaches the runner cutting position, the third position sensor 350 detects this and outputs a detection signal to the controller 510. The controller 510 receiving the saw 310 moves a moving source, for example, a third cylinder 352. Outputs the stop control signal, and receives the stop control signal, the third cylinder 352 stops the operation, and the rotating body 323 moves in one direction by the stop of the operation of the third cylinder 352. Therefore, the first chainsaw 310 also stops moving further.

Drive ”(distinguished from“ rotational movement ”in which the first chainsaw 310 moves by rotation)] Outputs a chainsaw rotary drive stop control signal for stopping itself to the first chainsaw 310, Chainsaw 310 is the rotation itself is stopped.

On the contrary, when the cutting of the runner 20 is completed and the rotation of the first chainsaw 310 is stopped and the first chainsaw 310 is in the runner cutting position, the controller 510 moves the driving control signal. When output to the third cylinder 352 which is the driving source, the rotating body 323 is rotated in the other direction toward the first return position by the driving of the third cylinder 352, and the rotating body 323 is rotated by the rotational movement. When the first return position is reached, the third position detection sensor 350 detects this and outputs a detection signal to the control unit 510. The control unit 510 receives the stop control by the third cylinder 352, which is a moving driving source.

The controller 510 receives the stop control signal and outputs a stop control signal to the second transfer means, for example, the fourth cylinder 420. One fourth cylinder 420 stops the operation, and the second chain saw 410 stops the linear movement of the forward by the operation stop of the fourth cylinder 420.

On the contrary, when the second chainsaw 410 is in the bur cutting position, the controller 510 outputs the driving control signal to the fourth cylinder 420 which is the second conveying means. When the second chain saw 410 moves backward toward the second return position by the driving of the 420 and the second chain saw 410 reaches the second return position by the linear movement of the reverse, the fourth The position detecting sensor 450 detects this and outputs a detection signal to the control unit 510. The receiving control unit 510 outputs a stop control signal to the fourth cylinder 420, which is the second transfer means, and stops the control. The fourth cylinder 420 receiving the signal stops the operation, and the second chain saw 410 is stopped at the second return position by the stop of the fourth cylinder 420.
