The degree of lateral movement of the limit line 63c formed on the tracking roller support shaft 63b is continuously sensed and the position information of the tracking roller 61 in accordance with the lateral movement of the tracking roller 61 To the control module 70 so that the left and right sliding bodies 41 can be moved in the left-right direction and the moving degree can be adjusted.

That is, when the tracking roller 61 is moved to the left by the leftward movement of the steel pipe 300 and as a result, the tracking roller support shaft 63b to which the tracking roller 61 is connected is moved in the leftward direction, The limit line 63c formed on the support shaft 63b also moves in the left direction. The limit line detection sensor 63d senses the movement of the limit line 63c in the left direction and transmits the left movement position information of the tracking roller 61 to the control module 70. The control module 70 The left and right slide bodies 41 are moved in the left direction by operating the drive motors 42a included in the left and right sliding modules 40 so that the cutting cutters 10 of the milling module 50 fastened to the left and right slide bodies 41, So that the joining portion 110 can be continuously cut along the previously formed joining portion 110.

When the steel pipe 300 moves to the right, the limit line detection sensor 63d generates information on the movement direction of the rightward movement of the tracking roller 61 and transmits it to the control module 70 so that the left and right slide bodies 41, So that the cutting cutter 10 of the milling module 50 fastened to the joining portion 50 is moved to the right to continuously cut the joining portion 110 along the previously formed joining portion 110.

In addition, a weight 63e may be provided under the guide frame 63a. In other words, the weight 63e is formed such that the tracking roller 61 provided at a portion corresponding to the upper portion of the guide frame 63a continuously rotates about the connecting portion between the guide frame 63a and the tracking roller support shaft 63b The weight of the upper portion of the guide frame 63a positioned on the upper portion of the connection portion between the guide frame 63a and the tracking roller support shaft 63b and the tracking roller 61 The weight of the lower portion of the guide frame 63a and the weight of the weight 63e located at the lower portion of the connecting portion between the guide frame 63a and the tracking roller support shaft 63b is greater than the combined weight .

That is, the weight 63e is continuously positioned below the vertical portion of the connecting portion between the guide frame 63a and the tracking roller support shaft 63b due to gravity, Since the roller 61 is continuously positioned vertically above the connection portion between the guide frame 63a and the tracking roller support shaft 63b, the steel pipe 300, which is formed by the crushing of the steel pipe 300, 300 can protrude or inwardly protrude from the end circle, the tracking roller 61 can continuously maintain the inner state of the joint portion 110.

That is, an extended frame 63f extending to be separated from the end of the tracking roller supporting shaft 63b is formed in a part of the guide frame 63a, and the extending frame 63f is provided with the tracking roller supporting shaft And an auxiliary sensing sensor 63g that senses an interval between the distal end of the first sensor 63b and the distal end of the second sensor 63b.

At this time, the elongated frame 63f is formed to have a length in a direction corresponding to a certain portion of the left or right side of the guide frame 63a, so that a certain portion of the elongate frame 63f is located further to the left or right than the left end or right end of the follower roller support shaft 63b .

In addition, a certain portion of the distal end of the elongated frame 63f may be bent so that the auxiliary sensor 63g may be positioned at a position corresponding to the end of the tracking roller support shaft 63b.

The auxiliary sensor 63g is of the same type as the optical sensor and is coupled to the elongated frame 63f in a state spaced apart from the distal end of the tracking roller support shaft 63b so as to be movable in the left- It is possible to control the movement of the left and right sliding bodies 41 in the lateral direction and the movement of the left and right sliding bodies 41 by sensing the distance between the ends of the auxiliary sensor 63g and the trailing roller support shaft 63b.

At this time, the limit line detection sensor 63d and the auxiliary detection sensor 63g may be operated collectively, and usually only one of the detection sensors operates, and when any one of the detection sensors malfunctions And the other detection sensor may be configured to automatically operate in place of any one of the detection sensors.

The position information (left-right direction position information) of the tracking roller 61 sensed by the limit line sensor 63d or the auxiliary sensing sensor 63g having the above-described configuration is used for the lateral movement of the left and right sliding bodies 41 And is transmitted to a steel pipe rotating device 200 that rotates a steel pipe 300 to be processed as a joint part 110 according to the present invention so that the steel pipe rotated and rotated by the steel pipe rotating device 200 (Which is the same as the longitudinal direction of the pair of steel pipes 300).
