The lug cutting apparatus 2 can be mounted on the traveling unit 305 and the lug cutting apparatus 2 mounted on the traveling unit 305 can be separated from the traveling unit 305. [

2, the lug cutting apparatus 2 includes guide rails 121 and 123 and a first cutting unit 101 and a second cutting unit 111 which are installed side by side on the guide rails 121 and 123, . ≪ / RTI >

The first cutting unit 101 and the second cutting unit 111 serve to drive the cutter, and in some embodiments of the present invention, the first cutting unit 101 and the second cutting unit 111 are provided in the example A cutting motor for driving and rotating the first cutting cutter 103 and the second cutting cutter 113. The first cutting unit 101 and the second cutting unit 111 can move to approach each other along the guide rails 121 and 123 or to move away from each other. In some embodiments of the present invention, the guide rails 121, 123 may be formed on the base 125 of the lug cutting apparatus 2.

A first cutting cutter 103 and a second cutting cutter 113 may be provided on the lower end of the first cutting unit 101 and the second cutting unit 111, respectively. The first cutting cutter 103 and the second cutting cutter 113 correspond to a blade for cutting the lug and in some embodiments of the present invention the first cutting cutter 103 and the second cutting cutter 113 correspond to the blade, For example, a disc shape. In some embodiments of the present invention, the direction of rotation of the first cutting cutter 103 and the second cutting cutter 113 may be opposite to each other. When it is confirmed that the lug 401 (see FIG. 10) exists between the first cutting cutter 103 and the second cutting cutter 113, the first cutting cutter 103 and the second cutting cutter 113, The lugs 401 between the first cutting cutter 103 and the second cutting cutter 113 can be cut.

The lug cutting apparatus 2 according to an embodiment of the present invention includes lug detecting sensors 105 and 115 for detecting a lug 401 between the first cutting cutter 103 and the second cutting cutter 113, . ≪ / RTI > In FIG. 2, the first lug detecting sensor 105 and the second lug detecting sensor 115 are shown as two sensors, but the number of the detecting sensors is not limited to two.

The lug cutting apparatus 2 according to an embodiment of the present invention may further include a first cutting unit 101 and a second cutting unit 111 in accordance with the size of the lug 401, And an interval adjusting unit 131 for adjusting the interval.

A lug cutting apparatus 2 according to an embodiment of the present invention is disposed between a first cutting unit 101 and a second cutting unit 111 and includes a first cutting unit 101 and a second cutting unit 111 And a limit unit 133 for setting a minimum interval.

3 and 4 are views for explaining an operation example of a lug cutting apparatus according to an embodiment of the present invention.

Referring to FIG. 3, it can be seen that the first cutting unit 101 and the second cutting unit 111 move closer to each other as compared with FIG. 2, and the distance between the first cutting unit 101 and the second cutting unit 111 becomes narrower. This operation can be performed by the interval adjusting unit 131 described above. That is, when the lug detecting device 105 detects the lug 401 between the first cutting cutter 103 and the second cutting cutter 113 by the lug detecting sensors 105 and 115, the first cutting unit 101 And the second cutting unit 111 can be moved at an appropriate interval to cut the lug 401. Further, the first cutting cutter 103 and the second cutting cutter 113 can be rotated. Referring to FIG. 4, the first cutting cutter 103 and the second cutting cutter 113 rotate in opposite directions to cut the lug 410 while moving toward the lug 401.

1, while the lug cutting apparatus 2 is operating, the running unit 305 to which the lug cutting apparatus 2 is mounted moves the lug cutting apparatus 2 to the traveling frames 301 and 311 So that the cutting operation is continued along the longitudinal direction of the lug 410. To this end, traveling guide rails 303 and 313 for moving the traveling unit 305 may be formed on the traveling frames 301 and 311. [ Cutting from the side of the lower end of the lug 410 in this manner results in not only a very small amount of lug 410 remaining after cutting but also a shortened cutting time.

If the lugs 410 are all cut and the lugs 401 are no longer detected between the first cutting cutter 103 and the second cutting cutter 113 by the lug detecting sensors 105 and 115, Can stop the rotation of the first cutting cutter 103 and the second cutting cutter 113. [
