Description
Technical field
The present invention relates to a kind of CUT monitoring system.
Background technology
As shown in Figure l, general, while according to conventional art, carrying out cutting technique, operating personnel will be arranged on PCD (PCD:PlasmaCutting Device; Hereinafter referred to as " PCD ") the PCD cutting nozzles la (Tip) of cutting torch 1 (Torch) lower end near cut member after, utilization, from the plasma arc (Plasma-Arc) of PCD cutting nozzles 1a ejection, is cut the step of cut member 2.
Now, be arranged on the PCD cutting nozzles 1a of PCD cutting nozzles 1 (Torch) lower end directly towards cut member 2, therefore, the abrasion of this PCD cutting nozzles 1a or the very large impact of the impaired mass formation on cutting technique.If, when excessive wear or impaired PCD cutting nozzles 1a are used for a prolonged period, the serious problem of operation can occur to re-start because of the impaired needs of cut member 2.Thus, operating personnel need to judge the wear intensity of PCD cutting nozzles 1a or whether impaired, should before because of PCD cutting nozzles 1a, cutting unfavorable condition, end cutting operation, or stop immediately cutting operation when bad cutting occurs.
Usually, as the whether impaired conventional method in the past of judgement PCD cutting nozzles 1a, can enumerate, for example, according to the method for operating personnel's micro-judgment, according to the method judged service time, sound inducing method, electric malice induction method, ultrasonic sensing method etc.
In described all multi-methods, according to the method for operating personnel's micro-judgment, be, near the variation that operating personnel need to hark sound PCD cutting nozzles 1a, the visual variation of perhaps observing PCD cutting nozzles 1a light is judged, therefore, exist and must rely on the problem of practician's experience, and need to wait in cutting operation process in the other problem of being monitored of PCD cutting torch 1 always.Moreover, according to the method for judgement service time, because according to surrounding enviroment and cut member 2, its service time is also different, therefore, has the problem that reliability is low.In addition, the method judged according to sound and ultrasonic wave, voltage, in the situation that the method that the state of the sound that the impaired basis of PCD cutting nozzles can be responded to and ultrasonic wave, voltage judges, therefore easily because of peripheral noise misjudgment, therefore, existence can't judge the problem of the wear intensity of the PCD cutting nozzles that can cause cutting undesirable level.
Especially, at the wear intensity of judgement PCD cutting nozzles 1a with when whether impaired, spacing distance S between the thickness T of cut member 2, cut member 2 and PCD cutting nozzles 1a, the gradient α of PCD cutting torch 1, for the many process conditions such as cutting speed that generate the required power supply value of plasma arc (plasma-arc), PCD cutting torch 1, be combined into a process conditions bag, produce much impacts.But, described traditional method in the past for example, according to the method for operating personnel's experience, according to the method for judgement service time etc.), exist and can't reflect the serious problem of aforementioned various operation parameters fully in the impaired deterministic process of PCD cutting nozzles 1a.
In recent years, as the method addressed these problems, Japanese Laid-Open Patent proposes for No. 2000-210768, after the sound of following cutting technique to produce in collection, judge according to this sound the method whether cutting technique normally carries out, Japanese Laid-Open Patent proposes for No. 2001-87863 to use the collection mixer automatically to detect the method for the bad generation of cutting.
But, these methods (signal measurements of sound, ultrasonic wave, voltage etc.) in the past fail to break away from traditional view, or the sound that simple Collection and use follows cutting technique to occur, the judgement that because outside noise (the various sound produced in operation in factory and the noise of supersonic band etc.) is arranged, can't be there is reliability.And, the method of the voltage signal between induction cutting torch and member, because the voltage change according to the abrasion of PCD cutting nozzles occurs hardly, therefore, can't judge the excessive abrasion of PCD cutting nozzles, only the PCD cutting nozzles is impaired, the generation cutting is bad just likely judges later.
Yet the confidence level of said method also is short of, so operating personnel are unwilling to use those methods.Even operating personnel adopt these methods as new " the impaired determination methods of PCD cutting nozzles 1a ", also can only be merely by be cut the thickness of member 2, the material of cut member 2 etc. scattered to be reflected to " the impaired determination methods of PCD cutting nozzles 1a " inner.For example, can't by being cut, asking between the thickness T of member 2, cut member 2 and PCD cutting nozzles 1a be spaced from the method to set up of the setting position of the gradient α of S, PCD cutting torch 1, sensor, sensor, generated the required power supply value of plasma arc, the various process conditions such as cutting speed of PCD cutting torch 1 are integrated into a process conditions bag, and using this each process conditions bag as " the impaired deterministic process of PCD cutting nozzles 1a " with each process conditions one to one basic data use.Finally, can't avoid the problem that the confidence level of the abrasion of Whole PC D cutting nozzles and impaired judgement is had a greatly reduced quality to occur.
In addition, under this situation, operating personnel one side based on do not meet fully present technological conditions, other process conditions state (excessive wear or be subject to strong criterion information is while carrying out a series of PCD cutting nozzles state deterministic process, finally can only bear therefore and the variety of issue occurred.For example, even the PCD cutting nozzles can occur, do not have impairedly, and judge into mistakenly this PCD cutting nozzles, oneself is impaired, even or the PCD cutting nozzles impaired, and fail to find the situation of this problem.
Have again, described method in the past (for example, No. 2000-210768th, Japanese Laid-Open Patent, disclosed methods such as No. 2001-87863rd, Japanese Laid-Open Patent etc.) in, ignore items such as " abnormalities (for example; follow cutting technique and the sound that produces exceeds the situation of predetermined normal range (NR) > last long ", merely at unusual condition (for example, the sound of following cutting technique and producing exceeds the situation of predetermined normal range (NR)) generation, the extreme measures of taking immediately to force arresting stop.Particularly, in sound or hyperacoustic situation, the similar sound, the ultrasonic wave noise that according to periphery, occur are done the judgement made mistake, even the generation of PCD cutting nozzles is bad because of the cutting of excessive wear, sound, ultrasonic wave or voltage signal still almost do not change, therefore, can't make correct judgement.
If, even operating personnel adopt these methods as new " state judging method of PCD cutting nozzles 1a ", these operating personnel still can't successfully manage because of PCD cutting nozzles excessive wear or the bad problem of the impaired cutting occurred.

On the one hand, by described each step, guaranteeing the body elastic wave signal of PCD cutting torch 1, in the situation of the specific PCD cutting nozzles state criterion information be consistent with " process conditions of current ongoing cutting technique ", as shown in Figure 5, the PCD cutting nozzles state of being controlled by PCD cutting nozzles condition monitoring control device 101 is judgment means 106 and induced signal receiving system 103 for the first time, PCD cutting nozzles state criterion information extracting device 105 grades communicate, read/guaranteed the body elastic wave signal of PCD cutting torch 1, the step of " the specific PCD cutting nozzles state criterion information that meets the process conditions of current ongoing cutting technique " etc.
Like this, after reading/guarantee the body elastic wave signal of PCD cutting torch 1, " the specific PCD cutting nozzles abrasion and the impaired criterion information that meet the process conditions of current ongoing cutting technique ", PCD cutting nozzles state judgment means 106 for the first time compares the body elastic wave signal of PCD cutting torch 1 and specific PCD cutting nozzles state criterion information, confirms whether the body elastic wave signal of this PCD cutting torch l exceeds the defined standard level L1 of specific PCD cutting nozzles state criterion information.If, confirm that the body elastic wave signal of this PCD cutting torch 1 has exceeded the defined standard level L1 of specific PCD cutting nozzles state criterion information, carry out and judge for the first time on the PCD cutting nozzles excessive wear or the impaired effect of occurring.
Certainly, the PCD cutting nozzles state criterion information of the present invention that is used for the determining step of state for the first time of described PCD cutting nozzles 1a is clearly to meet " process conditions of current ongoing cutting technique " therefore, under implementation environment of the present invention, according to PCD cutting nozzles state for the first time the resulting PCD cutting nozzles of judgment means 106 state judged result there is high reliability.
By described each step, carry out in the situation of " determining step of state for the first time of the PCD cutting nozzles 1a of the body elastic wave signal based on PCD cutting torch 1 ", according to PCD cutting nozzles state for the first time the function of judgment means 106 carry out that " the body elastic wave signal that is judged as PCD cutting torch 1 has exceeded the defined standard level L1 of specific PCD cutting nozzles state criterion information, L2 " time, the PCD cutting nozzles state of being controlled by PCD cutting nozzles condition monitoring control device 101 corresponding intrument 107 for the first time carries out a series of data generating routine, generate alarm data (warning lteral data, the warning graph data, warning light data, warning clause sound data etc. > after, by display window 100a, 10 loudspeakers 80, the alarm data that 70 outputs such as grade of warning indicator lamp generate.
Certainly, pass through above-mentioned steps, in the situation of a series of alarm data<warning lteral data, warning graph data, warning light data, warning clause sound data etc.>by outputs such as display window 100a, loudspeaker 80, warning indicator lamps 70, operating personnel can identify fast PCD cutting nozzles 1a because of excessive wear exist the bad danger of cutting (or, 1a is impaired for the PCD cutting nozzles), thereby, can effectively take appropriate measures.
On the one hand, by described each step, confirm for the first time PCD cutting nozzles 1a occur impaired (or, because there is the bad danger of cutting in excessive wear), and correspondingly, (for example taked a series of countermeasure for the first time, by display window 100a, loudspeaker 80, warning indicator lamp 70 lteral datas such as warning such as output such as grade, the warning graph data, warning light data, the measure of warning clause sound data etc.) in situation, as shown in Figure 6, the PCD state of being controlled by PCD cutting nozzles condition monitoring control device 101 for the second time judgment means 108 and PCD cutting nozzles state for the first time judgment means 106 communicate, whether the body elastic wave signal of confirming PCD cutting torch 1 exceeds the defined standard level L1 of specific PCD cutting nozzles state criterion information, L2.
Exceed the defined standard level L1 of specific PCD cutting nozzles state criterion information, L2 if confirm as the antibody elastic wave signal of PCD cutting torch 1, the PCD state for the second time judgment means 108 read immediately the temporal information in the body elastic wave signal that is recorded in cut member 2, and judge PCD cutting torch 1 body elastic wave signal standard level L1 the disengaging situation whether in specific PCD cutting nozzles state criterion information during defined a series of standard time St in lasting (with reference to Fig. 6) always.
Now, standard level L1, the L2 that confirms as the body elastic wave signal of PCD cutting torch 1 breaks away from situation in the situation that always lasting in during defined series of standards time St in specific PCD cutting nozzles state criterion information, and PCD cutting nozzles state judgment means 108 for the second time is judged as for the second time at once on PCD cutting nozzles 1a excessive wear or impaired (please refer to Fig. 6) have occurred.
