Description

[0001] PLASMA CUTTING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a plasma cutting apparatus capable of easily supplying and setting a material capable of minimizing a defective rate by performing precise setting for supplying a material with a plasma cutting apparatus and accurately cutting the material after cutting .

In general, materials such as fluorescent lamps and pipes used in structures are cut and processed by assembling or welding to comply with the intended use.

The cutting of the fluorescent lamps and the pipes is performed by a plasma cutting device, and a CAD / CAM program is input to perform automatic cutting.

In this way, the cutting machine is required to supply the material smoothly in order to minimize the defect rate by the automation system, and it is also possible to minimize the defect rate by setting the exact material after the supply.

In this conventional plasma cutting apparatus, a workpiece is supplied through a workpiece supply unit, and a workpiece is pushed to one side by a cylinder at a side, and then the workpiece is transferred to an arc cutting apparatus and cut by an arc cutting apparatus.

In this way, the plasma apparatus that cuts the material by pushing it to the side and then transporting it can not accurately set the position at which the material is cut at a time. Materials that are not properly set can not be cut accurately, and there is a problem of discarding defective materials.

This problem is caused by the problem of rising cost, and when the defective material is used as a building, it causes the construction of the defective building.

In order to solve the above problems, it is urgently required to develop a plasma apparatus capable of smoothly supplying a material and setting and cutting a precise material as well as supplying it.

Hereinafter, the operation and operation of the plasma cutting apparatus according to the present invention will be described.

First, as shown in FIG. 1, a CAD / CAM program for cutting a material to be cut is input to the control unit of the plasma cutting apparatus 10.

As shown in FIGS. 1 and 2, the work to be machined is conveyed to the feed conveyor 110 by the feeder 200 in a state of being stacked on the workpiece stacking portion, After the setting is performed, processing is performed by an arc cutting device of the machining portion, and the machined material is sorted and discharged according to the length by the material sorting device.

In more detail, as shown in FIGS. 1 and 2, the material is disposed in the workpiece mounting portion.

On the other hand, it is preferable that the rear end of the feeding device is arranged to be directed to the workpiece stacking portion, and the tip end portion is disposed between the feeding conveyors 110.

In order to feed the material, the feeder 200 preferably operates the cylinder 240 provided on the die 210 to maintain the feeder body 220 in a state of being rotated upward about the rotation axis 250.

When the drive motor 211 operates in this state, the sprockets 221a and 221b interlocked by the chain 222 rotate. When the material of the material loading portion is placed on the upper chain 222 of the supply body 220, the material is transported and supplied onto the supply conveyor 110 by the rotated chain 222.

When the supply is completed, the cylinder 240 is operated to lower the supply body 220 so that the material is seated on the roller 112 disposed on the supply gun bear 110.

When the material is seated in this way, the material is advanced by the roller 112 rotated by the driving motor 115, and the material to be fed is fed by the material aligning device 120 provided at the side of the feed conveyor 110 And is aligned in one direction while being pushed by the side ends of the guide rollers 121 provided on the side portions.

That is, when the material advances to some extent, the cylinder 123 of the material aligning device 120 operates to advance the pressure roller 122 to push the material and closely contact the guide roller 121.

The workpiece closely adhered to one end of the workpiece is continuously advanced, and the workpiece setter 300 collects information about the re-set and the workpiece, and sends the collected information to the controller to cut the workpiece.

When the material is directed to the guide roller 310, the actuating cylinder 321 of the side setting device 320 is actuated to push the side setting roller 322 toward the guide roller 310, , The distance that the side setting roller 322 is pushed is input to the control section.

Also, the operating cylinder 335 of the upper setting device 330 is operated to lower the upper setting roller 334, and at the same time, the gear gear 336 engaged with the pinion 337 is lowered.

At this time, the detection sensor 338 senses the number of revolutions of the pinion 337 when the lever gear 336 is lowered, and the descending distance of the upper setting roller 334 is transmitted to the control unit.

As described above, the moving distance of the side setting roller 322 and the falling distance of the upper setting roller 334 measure the width and height of the inserted material, and firmly fix the material during the cutting process.

As described above, the width and height of the inserted material are transmitted to the control unit, and the cutting process is performed according to the input range of the material.

On the other hand, the cutting position of the material is set by the rotation detecting roller 311. That is, the input material rotates the rotation detecting roller 311 and detects the number of revolutions by which the rotation detecting roller 312 detects the number of revolutions, and when the cutting position is exceeded, the motor 350 And the material is transported to the rear end by reverse rotation.

That is, when the material is input to the material setting unit 300, the side setting device 320 and the upper setting device 330 are operated to firmly set the material to be input, and at the same time, the side setting roller 322 and the upper The control unit detects the movement distance value of the setting roller 334 and detects what kind of material is inserted.

When the type of the inserted material is input, the material is processed according to the processing value according to the type of the material already input.

In addition, the cutting position of the material is detected by the rotation detecting sensor 312 and the rotational speed of the rotation detecting roller 312 is accurately set to perform cutting.

When the cutting position is correctly set as described above, the work is cut by the arc cutting device 410 of the machining part 400.

By confirming the information of the precisely inputted material and processing the material by setting the cutting position, the material of the material according to the production of the product can be minimized and the defect rate can be minimized.

On the other hand, the cut materials are sorted and sorted by the automatic sorting apparatus 500.
