Of course, the supply roller 178 of the supply device 170 installed in the discharge transfer means 140 may also be connected to the power transmission means 210 and rotated, but it is not necessary to connect.

Now, referring to "A", the workpiece 300 is mounted on the feed transfer means 130. Then, the operator presses the start button through the control unit 230 to operate. First, the control unit 230 operates the drive motor 200, the rotational force of the drive motor 200 is the feed roller of the feed transfer means 130 and the discharge transfer means 140 through the power transmission means 210 ( 132 and 142 are rotated and the feed roller 178 of the feeder 170 installed at the end of the feed transfer means 130 is rotated. Then, the workpiece 300 is transferred toward the plasma arc cutting device 120 along the feed roller 132 of the feed transfer means 130. At this time, the first sensor 192 installed on the frame 131 of the supply transfer means 130 generates a signal by recognizing the workpiece 300 to be transferred, the control unit 230 for recognizing the signal is a guide means The piston 167 of the pneumatic cylinder 166 of 160 is discharged gradually. Then, the workpiece 300 is conveyed in close contact with the roller 164 side of the first guide 162 by the roller 169 of the second guide 165 attached to the end of the piston 167.

Of course, the guide means 160, which is installed in plural, guides the workpiece 300 sequentially by the above operation.

Now, referring to "I", the workpiece 300 which is aligned and conveyed by the guide means 160 is adjacent to the second sensor 194 provided in the support plate 150. Then, the second sensor 194 immediately generates a signal, and the control unit 230 receiving the signal reverses the piston 182 of the pneumatic cylinder 181 of the elevating means 180. The supply device 170 attached to the lifting means 180 is lowered. At the same time, the workpiece 300 is adjacent to the third sensor 196, the third sensor 196 immediately generates a signal, the control unit 230 receiving the signal is the rotation of the drive motor 200 Will be emphasized. In this process, the supply device 170 installed in the supply transfer means 130 continues to descend so that the supply roller 178 restrains the upper part of the workpiece 300. Of course, the feed roller 178 also stops rotating.

Next, referring to "C", the plasma arc cutting device 120 processes the workpiece 300 in accordance with the processing information input to the control unit 230 to the workpiece 300 is stopped. When the machining is completed, the controller 230 moves the driving motor 200 again to transfer the workpiece 300. Of course, the distance is processed and stopped again to repeat the control to allow the plasma arc cutting device 120 to be processed. Here, the feed roller 178 of the supply device 170 installed in the supply feed means 130 in the transfer process of the workpiece 300 is constrained the upper portion of the workpiece 300 and is conveyed by rotation at the same time more In addition to accurate feeding, the transfer stability is greatly improved. In addition, since the sludge of the workpiece 300 discharged by the processing is collected in the collection box 242 through the discharge port 240, the post-treatment can be easily performed.

Subsequently, when the end of the workpiece enters the discharge transfer means 140 in this process, the control unit 230 lowers the supply device 170 installed in the discharge transfer means 140 to discharge the workpiece 300. The upper part is restrained to improve the transport stability. Thus, after the arc cutting device cuts the workpiece 300 to a predetermined length, the controller 230 raises the feeder 170 installed in the discharge transfer means 140 so that the worker can lift the finished workpiece. Works.

Therefore, according to the robot plasma cutting device 100 of the present invention, if the workpiece 300 is placed in the feed transfer means 130 is automatically processed and cut and discharged, thereby greatly improving the processing speed and work efficiency Maximization can be maximized, and the safety of the operator can be greatly improved by automation.

The foregoing has outlined rather broadly the features and technical advantages of the present invention in order to better understand the claims of the invention which will be described later. Additional features and advantages constituting the claims of the present invention will be described below. It should be recognized by those skilled in the art that the conception and specific embodiment of the invention disclosed can be used immediately as a basis for designing or modifying other structures for carrying out similar purposes to the invention.

As described above, according to the robot plasma cutting device of the present invention, if the workpiece is placed in the feed transfer means is automatically processed and cut and discharged, thereby greatly improving the processing speed and maximizing the work efficiency, By automation, the safety of the operator can also be greatly improved.
