Description

[0001] Plasma cutting apparatus using a 2D / 3D CAD cam [0002] PLASMA CUTTING APPARATUS USE 2D / 3D CAD CAM [0003]

The present invention relates to a plasma cutting apparatus, and more particularly, to a plasma cutting apparatus, which simplifies drawing operations using a 2D / 3D CAD cam, and more accurately collects and sets information And more particularly, to a plasma cutting apparatus and a cutting method using a 2D / 3D CAD cam for performing cutting and minimizing a defect rate while automatically cutting the cut material and performing stacking.

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 the use of the defective material as a building is causing the construction of the bad building.

In addition, in order to solve the above-mentioned problem, it is urgently required to develop a plasma apparatus capable of smoothly supplying a material and setting and cutting a precise material in addition to supply.

As an example of a conventional cutting apparatus, a robot plasma cutting apparatus of the registered patent application No. 10-0753201 filed by another applicant is an example.

The conventional plasma cutting apparatus includes a feed conveying means 130 for feeding and conveying a material, an arc cutting apparatus 120 for cutting the fed material by an inputted CAD / CAM program, And a discharge conveying means 140 for discharging the cut material.

That is, when the material to be machined is placed on the upper end of the feed and conveying means 130 by a separate device (forklift or crane), the material is moved to the arc cutting device 120 by the feed and conveying means 130, The material is pushed in one direction at the time of movement and is set.

In this state, the work is performed by the arc cutting apparatus 120, and the material that has been cut is transferred to the other side by the discharge conveying means 140 and is stacked with the loading box.

These cutting devices are used to machine materials of various lengths.

However, since such a cutting apparatus can not easily obtain the information of the material to be randomly input, it is inconvenient to set it again when machining a material having a different size (width, height and material shape) after processing only a single material .

In addition, since the accurate setting is not made during the processing of the material, a problem of defective rate is generated.

In addition, there is a problem that the above-mentioned plasma cutting apparatus has a problem that it is not possible to select a material having been cut through according to its length, and the processed material has a problem that various lengths of material are accumulated in a loading box without going through a presumptive assumption.

If the processed material having different lengths is wrapped like this, there is a troublesome problem that a worker has to separate separately, and accordingly there is a problem that a time for separation operation is separately required.

That is, there is a problem that efficiency of workability is lowered.

[ 2 loading box 540-2 and a third loading box 540-3.

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 by which the side setting roller 322 is pushed is input to the control unit 700. [

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.

When the cutting position is determined and the setting is completed, the multi-axial robot 411 is operated and the torch 426 of the cutter 420 is positioned on the surface of the workpiece.

At this time, the guide pins 425 provided at both ends of the torch 426 are brought into close contact with the surface of the work so as to cut the surface of the work.

On the other hand, even if a material having a large curvature is inserted, the cutting is performed in a state in which the guide pin 425 is in close contact with the surface of the workpiece, so that the torch 426 can be cut at a constant interval on the surface of the workpiece.

In addition, if the pressing force of the robot arm 412 greatly acts, the guide pin 425 pushes the cutter main body 422 by pressing force, and pushes the spring 424 while pushing it, so that the work can be smoothly processed.

Meanwhile, the harmful substances generated when the processing is performed as described above are collected by the dust collector 600.

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.

The material (material having a short length) thus cut is transferred to the first main body 511-1 by the first sorting machine 510 and is transported. The short material that has fallen into the first body moves to the inclined second body 511-2 and is separated and adhered to the first loading box 540-1 provided in front of the second body. Processing of such a short material is selectively carried out in the first loading box 540-1 by the first sorting machine when processing is performed.

When the intermediate material is processed, the second sorting machine 520 is subjected to the following sorting process. At this time, the medium-length material can be divided into upper and lower halves. In other words. If the distance from the start of the arc cutter to the entrance of the second sorting machine is shorter than the distance from the entrance of the second sorting machine, the intermediate length of the second sorting machine is regarded as intermediate, and the distance to the end of the second sorting machine is regarded as a higher grade. The material having a length longer than the end of the second sorter may be judged as a long material.

Thus, the intermediate sorting material can not be sorted through the second sorting unit 520. Since the length thereof is less than the distance of the second sorting device, it is dropped backward due to the weight load of the rear end cutting portion when it is moved to the second sorting device.

Due to such a problem, the roller 523 of the second sorting machine 520 must be lowered inward to prevent the intermediate material from being interfered with when cutting the intermediate material.

That is, when the cylinder 524 is operated upward and the link is rotated and raised, the rotation shaft 526 provided to interlock with the link 525 rotates, and the shelf 522 on which the roller 523 is disposed rotates inward 90 degrees.

When the intermediate sorting material is rotated downward, the intermediate material, which is processed and discharged, falls on the first sorting machine 510 without being interfered with by the second sorting machine, and is driven by the rollers disposed on the first and second bodies, (530).

At this time, it is preferable that the angle adjustment of the second main body is performed to a degree that the intermediate grade material is directed to the third sorting device.

The intermediate material conveyed to the third sorting device 530 via the first sorting device 510 is dropped on the second stacking tray 540-2.

On the other hand, the sorting feed of a long material is selected and transported by the following method.

At the time of cutting a long material, the rollers 523 of the second sorting machine 520 should be horizontal in a raised state.

In this state, when the front end portion of the long material is processed, the front end portion of the long material is pushed by the machining portion and is conveyed to the roller 523 of the second sorting machine 520. When the rear end portion of the long material is also cut, The roller 523 is rotated by the operation of the second separator 528 to convey the long material to the third separator 530. In this case, since the length is long, even after the front end of the work piece enters the third sorting machine, the second sorting machine pushes the rear end of the work, and thus the problem of falling back does not occur.

Also, even after the rear end passes through the secondary sorting device, the center of gravity is more attracted to the third sorting device, so that it is prevented from falling backward.

The material conveyed by the third sorting machine 530 is thus loaded into the third loading box 540-3.

As described above, according to the automatic sorter of the present invention, even if the material is short, middle or long, it is automatically sorted by the operator without separately sorting and loading, thereby minimizing the working time and improving the work efficiency .

The specific embodiments of the present invention have been described above.

It will be apparent to those skilled in the art that various modifications and variations can be made in the details of the present invention without departing from the spirit and scope of the invention as defined in the appended claims. You must understand.

Therefore, it should be understood that the above-described embodiments are provided to fully illustrate the scope of the invention to a person having ordinary skill in the art to which the present invention belongs, Are only defined by the scope of the claims.
