By along being depicted in line of cut 2 on steel plate 1 by steel plate 1 gas cutting by laser irradiation device 200 as described above, the blanking of product steel plate 1a completes.Below, the gas cutting of this 1st embodiment is described in detail.
Fig. 2 is the stereogram of the blanking system representing the state implementing gas cutting.As shown in Figure 2, steel plate 1 loads track 300, along this track 300, gas cutting device 400 is advanced.Above gas cutting device 400, the laser irradiation device 200 of the line of cut 2 of the shape representing product steel plate 1a is described in configuration.Gas cutting device 400 possesses arm 401, gas cutting cutting torch 402 (cutter), laser detector 403 and main part 405, implements gas cutting along line of cut 2.In addition, gas cutting device 400 is connected to the flexible pipe of supply gas, but omits in fig. 2.
In this 1st embodiment, gas cutting device 400 possesses at the upper arm 401 extended of the horizontal direction (the arrow Y-direction of Fig. 2) orthogonal with its travel direction (the arrow X-direction of Fig. 2).Further, be provided with gas cutting cutting torch 402 at this arm 401, gas cutting cutting torch 402 can move along the bearing of trend Y of arm 401.Gas cutting with cutting torch 402 from arm 401 downward (steel plate 1 side) extend.In the front end (lower end) of this gas cutting with cutting torch 402, be provided with towards the burner of steel plate 1 opening.In addition, at the lower end of gas cutting with cutting torch 402, the laser detector 403 detecting line of cut 2 (being irradiated onto the laser 201 on steel plate 1) is equipped.As laser detector 403, such as, can use CCD camera or laser sensor.
When implementing gas cutting, by operating the control device (not shown) of advancing controlling gas cutting device 400, gas cutting device 400 is advanced along track 300.Now, gas cutting cutting torch 402 is moved along the bearing of trend Y of arm 401, detects line of cut 2 to make laser detector 403.Thereby, it is possible to the position of the Y-direction of gas cutting cutting torch 402 is adjusted automatically, to make the position of gas cutting cutting torch 402 (position of burner) consistent with line of cut 2.That is, can while make gas cutting device 400 advance along the direction X of track 300, the mode of following line of cut 2 with gas cutting cutting torch 402 implements gas cutting.In addition, above-mentioned control device both can be possessed by gas cutting device 400, also can with gas cutting device 400 separate configuration.
As described above, gas cutting cutting torch 402 possesses laser detector 403, and the bearing of trend along arm 401 moves, and implements gas cutting thus along line of cut 2.Therefore, when being placed on steel plate 1 by track 300, in the past such tightness is not required for line of cut 2 and the position relationship of track 300.That is, do not need temporarily after track 300 is placed on steel plate 1, first gas cutting device 400 advanced and confirm the operation of gas cutting cutting torch 402 above line of cut 2 etc.
In fig. 2, the line of cut 2 illustrated along the side on the length direction being in steel plate 1 (X-direction of Fig. 2) implements the state of gas cutting, but when implementing gas cutting along other lines of cut 2, after suitably again being loaded by track 300, repeat identical operation.
In this 1st embodiment, as shown in Figure 2, arm 401 is supported by rotating shaft 404, by the rotation of rotating shaft 404 the arrow r of the Fig. 2 (towards), can by arm 401 towards change 180 °.Namely, although also depend on that the plate of steel plate 1 is wide, but by change after implementing gas cutting along the line of cut 2 of the side on the length direction being in steel plate 1 arm 401 towards, track 300 need not be loaded again and just then can implement gas cutting along the line of cut 2 of the opposing party.
In addition, the structure of the gas cutting device 400 shown in Fig. 2 is examples, is not limited to this.Such as, be not limited to the structure of the arm 401 used as shown in Figure 2, as long as cutting mechanism gas cutting cutting torch 402 can the structure of movement at least one horizontal direction different at the direct of travel (bearing of trend of track 300) from gas cutting device 400 just passable.
As described above, in this 1st embodiment, the gas cutting device 400 possessing laser detector 403 and the laser irradiation device 200 describing line of cut 2 separately configure.Therefore, it is possible to the operation and torch operation of describing line of cut are implemented simultaneously.And then, the impact that track 300 brings relative to the dimensional accuracy of position on the product steel plate 1a after cutting of steel plate 1 can be reduced.
Gas cutting device 400 is connected to the flexible pipe 600 of supply gas, but as shown in Figure 3, line of cut 2 exists flexible pipe 600, likely flexible pipe 600 is cut by mistake.Be described with reference to the action of Fig. 3 to the gas cutting device 400 in this situation.
Fig. 3 is the side view of the blanking system representing the state having flexible pipe 600 on line of cut 2.As shown in Figure 3, laser irradiation device 200 is configured in the top of steel plate 1, irradiates laser 201 and describes line of cut 2 on the surface of steel plate 1.In the case, because laser 201 is blocked by flexible pipe 600, so there is the region 601 of line of cut 2 in the below of flexible pipe 600.On the other hand, gas cutting device 400 possesses laser detector 403, detects the line of cut 2 being in the front of travel direction (X-direction of Fig. 3).When being cut by steel plate 1, gas cutting device 400 is advanced on track 300, if but the detection position of laser detector 403 reaches the region 601 that there is not line of cut 2, then line of cut 2 can not be detected.Gas cutting is made to stop in the case.Therefore, it is possible to reliably prevent flexible pipe 600 cutting by mistake.
Then, with reference to Fig. 4, the management devices 500 of the blanking of management steel plate is described.As shown in Figure 4, management devices 500 is connected with camera head 100 and laser irradiation device 200.Management devices 500 is such as realized by the computer installation possessing CPU (Central Processing Unit), ROM (Read OnlyMemory), RAM (Ramdom Access Memory) etc.
The laser irradiation that laser irradiates control part 501 pairs of laser irradiation devices 200 controls, and such as, based on the size (length and width) of the product steel plate 1a sent from higher level's computer in advance, describes line of cut 2 as shown in Figure 1 on steel plate 1.
In addition, also under laser irradiates the control of control part 501, laser irradiation device 200 can be utilized, the product steel plate 1a as shown in Figure 5 before cutting or after cutting describes character or image.In the case, such as can adopt the production number etc. in advance sent from higher level's computer is painted on the surface of product steel plate 1a, operator carries out hand-written occupation mode in the mode of being drawn.Thereby, it is possible to prevent the production number by mistaking hand-written on product steel plate 1a.In addition, the laser irradiation device being used for describing to product steel plate 1a character or image also can be other laser irradiation devices different from laser irradiation device 200.
Image acquiring section 502 obtains the image taken by camera head 100.Camera head 100 not only takes steel plate 1 as described above, can also take the product steel plate 1a after the steel plate 1 of the state being placed with track 300, cutting.In addition, both can be the product steel plate 1a after 1 camera head 100 takes the steel plate 1 before cutting and cutting, also can be the multiple camera head 100 of configuration, each camera head 100 takes steel plate 1 and product steel plate 1a respectively.
And then camera head 100 also can take the steel plate 1 in cutting.In the case, also as described above, image acquiring section 502 obtains captured image.
Outline identification portion 503, based on the image of the steel plate 1 before the cutting of being taken by camera head 100, identifies the profile 1b (with reference to Fig. 1) of steel plate 1.In the case, such as, the edge of steel plate 1 detects based on the brightness change in photographed images in outline identification portion 503, identifies the profile 1b of steel plate 1.
Like this, before describing line of cut 2 by laser irradiation device 200, steel plate 1 taken by camera head 100, can outline identification portion 503 identifies the profile 1b of steel plate 1, can carry out the confirmation of the blanking of the product steel plate 1a that implement to have the size that such as never illustrated higher level's computer sends in advance thus.
Cutting could detection unit 504 on steel plate 1, be placed with track 300 state under, based on the image of the steel plate 1 taken by camera head 100, judge whether track 300 is loaded into there is line of cut 2 in the movable range of gas cutting cutting torch 402.
Describing cutting cutting torch 402 owing to can move along arm 401, so do not require tightness when loading track 300 for line of cut 2 and the position relationship of track 300, but certainly needing line of cut 2 to be present in the movable range of gas cutting cutting torch 402.
So based on the image of steel plate 1 of state being placed with track 300, cutting could judge whether track 300 is loaded into there is line of cut 2 in the movable range of gas cutting cutting torch 402 by detection unit 504.In addition, because needs automatically identify track 300 in photographed images, so preferably implement mark etc. to track 300 in advance.
Under line of cut detection unit 505 describes the state having line of cut 2 on the surface of steel plate 1, based on the image of the steel plate 1 taken by camera head 100, judge line of cut 2 on the surface of steel plate 1 whether continued presence.
As described above, line of cut 2 exists flexible pipe 600, there is the region 601 of line of cut 2.In the case, owing to there is not the region 601 of line of cut 2, the state that line of cut 2 one-tenth is off.That is, on the surface of steel plate 1, line of cut 2 is discontinuous.So describe the state having line of cut 2 on the surface of steel plate 1 under, steel plate 1 taken by the camera head 100 be configured on steel plate 1, under being judged to be the discontinuous situation of line of cut 2 by line of cut detection unit 505, makes cutting stop.Therefore, it is possible to reliably prevent flexible pipe 600 cutting by mistake.
Cutting correctness detection unit 506 is based on the image of the steel plate 1 taken by camera head 100 in the cutting of steel plate, identify the difference of line of cut 2 and cutting position (position of Gas-cutting torch 402), judge this difference whether in the tolerance dimension of regulation.
As described above, by detecting line of cut 2 by laser detector 403, implement gas cutting along line of cut 2, but in laser detector 403 error detection line of cut 2, cutting can not be implemented along line of cut 2, decrease in yield.So, when being judged to be that by cutting correctness detection unit 506 difference of line of cut 2 and cutting position in the cutting at steel plate is outside the tolerance dimension specified, cutting is stopped.Therefore, can determine whether to cut along line of cut 2 by cutting correctness detection unit 506, can decrease in yield be prevented.
Dimension measurement portion 507, based on the image of the product steel plate 1a after the cutting of being made a video recording by camera head 100, measures the size of product steel plate 1a.By the size superior computer transmission of product steel plate 1a that determines and keeping.In addition, dimension measurement portion 507 judges that the size of the product steel plate 1a determined is whether in the tolerance of the size such as in advance sent from higher level's computer (within the scope of tolerable size).Further, when the size of the product steel plate 1a determined is outside tolerance, this situation can be notified to operator.
Character picture identification part 508, based on the image of the product steel plate 1a before the cutting of being taken by camera head 100 or after cutting, identifies the character and image that are handwritten on product steel plate 1a.Such as shown in Figure 5, the production number on hand-written product steel plate 1a after dicing can be identified, judge that this production number is whether number consistent with planned product.In addition, when to the hand-written character of the product steel plate 1a before cutting or image, may not be the product steel plate 1a after based on cutting, but carry out above-mentioned judgement based on the image of the product steel plate 1a before cutting.
