The second torch unit 250 is composed of a plasma discharge port (P) for emitting plasma to cut the workpiece, and a position sensor (S) for detecting the existence, position, and size of the workpiece,
When the position sensor S detects a workpiece, it transmits a signal to the second torch control unit TC2 to move the second torch unit 250 to the processing position,
The position detection sensor (S) has a sensor vertical axis (Sv) for adjusting the vertical movement of the sensor, a sensor horizontal axis (Sh) rotatably coupled to the lower end of the sensor vertical axis (Sv) to rotate the lead (L), the sensor It includes a lead vertical axis (Lv) coupled to one end of the horizontal axis (Sh) to adjust the vertical movement of the lead (L),
Plasma cutting device, characterized in that the lead (L) is formed in a Y-shape and both ends of the lead (L) divided into two contact the upper surface of the workpiece to accurately detect the position of the workpiece.
According to claim 5,
The second device receives the reference point data of the first torch controller after activating the position sensor in the second main controller and transmits a vertical movement signal to the second torch controller (S210);
Moving the second torch so as to come into contact with the workpiece (S220);
Moving the second post forward or backward to place it in a cutting position and fixing the position of the second torch unit (S230);
Starting displacement measurement by setting the position of the current position sensor as a reference point in the second torch controller (S240);
Stopping the position control of the second torch unit by blocking the control signal of the second torch control unit at the same time as the supply of torch power by the second main control unit (S250);
Starting a cutting operation by moving the second horizontal axis frame to the left or right (S260);
Cutting off the torch power and stopping the second horizontal axis frame after the cutting work is completed (S270);
Plasma cutting device characterized in that the length of the workpiece is precisely cut by operating in the order of the step (S280) of separating the second torch unit from the workpiece by transmitting the control signal of the second torch control unit at the same time as the torch power is cut off.
