(detection of " contact ")

Fig. 3 represents the circuit diagram (equivalent circuit diagram) detected the high-frequency signal produced on the heart yearn 152 of this wire processing apparatus 100.In the present embodiment, high frequency electric source 240 pairs of blades 104 (each blade 221,222,223) apply the high frequency voltage being controlled as constant voltage.In the circuit diagram shown in Fig. 3, electric capacity C1 represents the space electric capacity between blade 104 and electrode 242.Electric capacity C2 represents the electric capacity of heart yearn 152 and electrode 242.Switch S 1 represents the action of blade 104 relative to the insulator 154 of covered electric cable 150.Namely the state representation that switch S 1 is opened is separated with insulator 154 between blade 104 and heart yearn 152, and blade 104 does not contact with heart yearn 152.In addition, the state representation blade 104 that switch S 1 is closed contacts with heart yearn 152.In Fig. 3, the position shown in " G " is expressed as the position be electrically connected with machine ground connection (reference potential).

If blade 104 contacts with heart yearn 152, then Fig. 3 breaker in middle S1 is closed condition.Now, the voltage level variation large (see Fig. 4) electrode 242,244 produced.In the present embodiment, heart yearn 152 and electrode 242,244 form electric capacity C2.If blade 104 contacts with heart yearn 152, then the voltage level of heart yearn 152 becomes large.Blade 104 contacts with heart yearn 152, and the voltage level of heart yearn 152 increases, and the voltage level thereupon produced on electrode 242,244 becomes large.Therefore, signal detector 110 can based on the voltage level produced on electrode 242,244, detects the contact of blade 104 and heart yearn 152/do not contact.

In this case, by high frequency electric source 240, high frequency voltage is applied to each blade 221,222,223.By applying high frequency voltage to each blade 221,222,223, the heart yearn 152 of covered electric cable 150 induces high frequency voltage.And then, between the heart yearn 152 of this covered electric cable 150 inducing high frequency voltage and electrode 242,244, there is electrostatic coupling, electrode 242,244 induces high frequency voltage.

In the present embodiment, high frequency voltage is applied to each blade 221,222,223.Therefore, on the heart yearn 152 of insulator 154 close to each blade 221,222,223, there is electrostatic coupling, the heart yearn 152 of covered electric cable 150 induces voltage.In this stage, electrode 242,244 induces the voltage of roughly fixed level.If each blade 221,222,223 contacts with heart yearn 152, then the voltage that blade 221,222,223 applies is applied directly on heart yearn 152.Therefore, voltage level electrode 242,244 induced significantly rises.Based on the voltage level induced on electrode 242,244, the contact of each blade 221,222,223 and heart yearn 152 can be detected like this.

(judging based on the contact of signal waveform W0)

In order to detect the contact of each blade 221,222,223 and heart yearn 152, can set to the voltage level of the further filtering of high-frequency signal that will electrode 242,244 be detected and the signal waveform W0 after amplifying threshold value t1, the t2 (see Fig. 4) that specify.Such as, in the present embodiment, for high frequency electric source 240, output frequency can be used for 100kHz, output voltage is the high frequency electric source of-5V ~+5V.Whether the peak value (voltage peak) of signal waveform W0 contacts with heart yearn 152 according to each blade 221,222,223 and changes.In this case, threshold value t1, t2 can be set between the voltage level of this peak value.Such as, voltage level (voltage of peak value) when each blade 221,222,223 contacts with heart yearn 152 is roughly ± 5V, voltage level under each blade 221,222 and/or 223 and the discontiguous situation of heart yearn 152 is fully less than ± 3V, in this case, such as, threshold value t1, t2 can be set as the voltage level of-3V ,+3V.

Can detect on electrode 242,244 voltage level (more than below-3V or+3V) exceed or equal described threshold value t1, t2 high-frequency signal (signal of telecommunication), judge that each blade 221,222,223 contacts with heart yearn 152.In this case, also can such as when the stipulated time (or stipulated number) detect exceed or equal described threshold value t1, t2 voltage level, judge that each blade 221,222,223 contacts with heart yearn 152.

Thus, the situation etc. of voltage level detecting and exceed or equal threshold value t1, t2 instantaneously can be ignored, can misinterpretation be prevented.Such as, can when detect with 1ms (millisecond) exceed or equal specify threshold value t1, t2 voltage level, or detect exceed or equal defined threshold t1, t2 voltage level more than 10 times (being equivalent to 1ms under 100kHz) when, be judged to be that each blade 221,222 and/or 223 contacts with heart yearn 152.In addition, wire processing apparatus 100 also for the operating space of each blade 221,222,223, can preset the region of carrying out described contact and judging.Determinating area at least prepares a position.

(detection of " contact position ")

Blade edge position detector 106 can to by blade driving mechanism 105, a pair blade edge position of movement detects.Such as, in cut-out process or incision process, by blade edge position detector 106, the position (state, opening and closing amount) of each blade 221,222,223 when can detect each blade 221,222 and/or 223 and heart yearn 152 time of contact.In addition, this wire processing apparatus 100, by relative position detector 118F, 118R, detects covered electric cable 150 and blade 104 relative position (distance) along covered electric cable 150 length direction.Therefore, it is possible to covered electric cable when detecting each blade 221,222,223 and heart yearn 152 time of contact in peeling process 150 and the relative position (distance) of blade 104 along covered electric cable 150 length direction.

(cutting off process)

Below, to described wire processing apparatus 100, in the cut-out process of covered electric cable 150, the condition judgement (defective judgement) of covered electric cable 150 is described.

(test example 1 (cutting off process))

An example of relation between the position (state, opening and closing amount) that Fig. 4 represents the blade 104 (each blade 221,222,223) detected by blade edge position detector 106 and the high-frequency signal that detected by signal detector 110.In the diagram, in time shaft (transverse axis) top, represent the position (state, opening and closing amount) of blade 104 (each blade 221,222,223) detected by blade edge position detector 106, represent the high-frequency signal (signal waveform W0) at input signal detection device 110 in the same time mutually above it.

Here, Fig. 4 represents the relation between the position (state, opening and closing amount) such as cutting off cutting edge 221 in the operation of covered electric cable 150 by cutting edge 221 and the high-frequency signal detected by signal detector 110.In addition, here, the waveform of high-frequency signal for schematically to represent, but is actually the waveform of the high frequency of 100kHz, generates the waveform closeer than diagram relative to time shaft.

In addition, in the present embodiment, if cutting edge 221 contacts with heart yearn 152, then the voltage that cutting edge 221 applies is applied directly on heart yearn 152.Therefore, voltage level electrode 242 induced raises.Cut off by cutting edge 221 in the operation of covered electric cable 150, along with cutting edge 221 closes, insulator 154 is producing otch, afterwards, cutting edge 221 and heart yearn 152 come in contact.Further, completely closed by cutting edge 221, covered electric cable 150 is cut off.In the diagram, later half in cutting edge 221 closed action, detects the contact of cutting edge 221 and heart yearn 152.Described Fig. 4 is that covered electric cable 150 is by typical waveform graph when normal cutoff.

(region A, B)

In described cut-out process, such as, multiple regions of judgement " contact " can be preset to the moving area of blade 104 (referring to cutting edge 221 here) movement.Such as, in cut-out process, a pair cutting edge 221a, the 221b of concavity is used.In this case, as shown in Figure 4, a pair cutting edge 221a when the relative distance (inscribed circle diameter in the space formed by a pair cutting edge 221a, the 221b of concavity) of a pair cutting edge 221a to concavity being from a pair cutting edge 221a, 221b the state opened, 221b being reached the external diameter distance being equivalent to covered electric cable 150, the moving area of 221b are set to " A ", and the moving area closed completely to a pair cutting edge 221a, 221b from this position (with the suitable distance in opposite directions of the external diameter of covered electric cable 150) is set to " B ".Can pass through configuration part, above-mentioned first area 114, operator can carry out arbitrarily such region setting.In this case, preferably, such as, first half moving area " A " closed for cutting edge 221 can be chosen as the first abnormality juding region by operator.

Fig. 4 is by waveform graph typical when normal cutoff at covered electric cable 150.In the diagram, do not detect " contact " in the first half moving area " A " that cutting edge 221 is closed, and detect " contact " in the later half moving area " B " closed in cutting edge 221.Thereby, it is possible to judge that cutting edge 221 does not contact with heart yearn 152 in the first half moving area " A " that cutting edge 221 is closed, and covered electric cable 150 is suitably cut off.In addition, detected whether " contact " by such zoning, can while minimizing data volume, the state of the covered electric cable 150 exactly in the process of judgement electric wire.That is, wire processing apparatus 100 can carry out cut-out process once and strip process in 1 second, runs up.Therefore, judge that whether qualified also needs of each electric wire process carries out at short notice.In this case, realizing accurately in the whether qualified scope judged, preferably reduce and judge required data volume to whether qualified.

In addition, here with the position suitable with covered electric cable 150 external diameter for benchmark sets two regions A, B, but the setting in region not necessarily limit by described execution mode.Such as, for the moving area of blade 104 movement, multiple region can be set with the interval of regulation.In this case, by region setting is comparatively thin, phenomenon can be analyzed in detail, but on the contrary, data volume increases.Therefore, the region of right quantity is set.

(test example 2 (cutting off process))

This wire processing apparatus 100 can based on the position of the cutting edge 221 detected by blade edge position detector 106 (state, opening and closing amount), and the high-frequency signal (signal waveform W0) to be detected by signal detector 110, detect in the state cutting off the covered electric cable 150 in process.Relation between the position (state, opening and closing amount) that Fig. 5 represents the cutting edge 221 detected by blade edge position detector 106 and the high-frequency signal (signal waveform W0) that detected by signal detector 110.In Figure 5, under the state (state that cutting edge 221 is fully closed) of a pair cutting edge 221 separation, the voltage level of electrode 242 raises.Therefore, such as shown in Figure 6, the possibility that likely cutting edge 221 of covered electric cable 150 opposite central depression is cut-off under the state from blade central offset.

(test example 3 (cutting off process))

Fig. 7 represents the relation between the position (state, opening and closing amount) cutting off the cutting edge 221 detected by blade edge position detector 106 in process and the high-frequency signal (signal waveform W0) detected by signal detector 110 further.In the figure 7, cutting edge 221 is (cutting edge 221 is closed from the state opened, to opening again) on all positions, and the voltage level of electrode 242 is roughly constant not to be raised.In suitable cut-out process, at least detect and once contact, but in the test example of Fig. 7, heart yearn 152 is not once also detected with the contact of cutting edge 221.Therefore, such as shown in Figure 8, can consider have covered electric cable 150 to depart from the cut-out area configurations of cutting edge 221, carry out the possibility of cut-out action in this condition, or have signal detector 110 or heart yearn to damage may waiting of sensor failure.Can make wire processing apparatus 100 be configured to when detect as shown in Figure 7 waveform wire processing apparatus 100 is stopped.Because wire processing apparatus 100 stops, operator can go out waveform reason as shown in Figure 7 by check and inspection.

Like this, based on the position of the blade 104 detected by blade edge position detector 106, and the high-frequency signal (signal waveform W0) to be detected by signal detector 110, such as, can detect that cutting edge 221 and heart yearn 152 carry out the contact of the time of which kind of degree in which in moment.Thereby, it is possible to detect the state of the covered electric cable 150 cut off in process more accurately.

(strip process (incision process, peeling process))

Then, the test example in strip process is described.Here, be described for the strip process of F side, the strip process of R side is also identical.

Strip process has incision process and peeling process.Incision process is on the end of covered electric cable 150, makes to divest the process that sword 222 cuts insulator 154.Peeling process makes to divest while sword 222 cuts insulator 154, makes to divest sword 222 and covered electric cable 150 along the length direction relative movement of covered electric cable 150, divest the process of insulator 154 from covered electric cable 150.

(test example 4 (strip process))

Fig. 9 represents the position (state, opening and closing amount) divesting sword 222 (see Fig. 1) in above-mentioned incision process (the incision process in strip process) and the detection waveform (high-frequency signal (signal waveform W0)) detected by signal detector 110.Figure 10 represents covered electric cable 150 and the relative position divesting sword 222 and the detection waveform detected by signal detector 110 in the above-mentioned peeling process in strip process.Fig. 9 and Figure 10 illustrates respectively and illustrates the figure of detection waveform when carrying out suitable strip process.

(incision process)

In incision process, divest sword 222 and close, the insulator 154 of incision covered electric cable 150.In the present embodiment, the blade central portion depression of sword 222 is divested.In incision process, divest sword 222 as shown in Figure 9, close.Now, divest the position of sword 222 owing to caving on the central portion of blade, leave heart yearn 152 (see Fig. 2) and cut insulator 154.Then, divest sword 222 to open slightly.Thus, divest sword 222 and vacate distance to divest sword 222 under the state cutting insulator 154 with heart yearn 152.Therefore, divest sword 222 when the debarking action of the bearing of trend movement along covered electric cable 150, prevent from making heart yearn 152 cause damage owing to divesting sword 222.

Now, when carrying out suitably incision process, divesting the insulator 154 that sword 222 cuts covered electric cable 150, but not contacting with heart yearn 152.That is, as shown in Figure 9, divest sword 222 and close, in the action of incision insulator 154, detection waveform can not become large.Say scrupulously, owing to being processed by incision, make the varied in thickness of insulator 154, the degree along with electrostatic coupling changes, and detection waveform may become large a little.But, even if in this case, also can not as the situation of contact, detection waveform clearly becomes large.

In described incision process, such as, the region of multiple judgement " contact " can be preset to the moving area divesting sword 222 movement.Such as, as shown in Figure 9, also can set and divest the closed first half moving area " C " of sword 222, and it is closed to divest sword 222, the later half moving area " D " then opened a little.To the setting in such region, by configuration part, above-mentioned first area 114, operator can set arbitrarily.In addition, operator to the moving area setting abnormality juding region divesting sword 222,223 of incision process, can process different ground with cut-out and set in addition.

(peeling process)

Peeling process is divesting under the state that sword 222 cuts insulator 154, makes to divest the length direction relative movement along covered electric cable 150 of sword 222 and covered electric cable 150, by the process that insulator 154 divests from the end 150F of the F side of covered electric cable 150.Divest sword 222 under the state of incision insulator 154, divest sword 222 and open a small amount of distance with heart yearn 152 sky.When suitably carrying out peeling process with optimal state, divest sword 222 and do not contact completely with heart yearn 152.Therefore, as shown in Figure 10, make to divest sword 222 and covered electric cable 150 along in the action of the length direction relative movement of covered electric cable 150, detection waveform can not become large.

In described peeling process, such as, multiple region can be preset to covered electric cable 150 and the relative movement region divesting sword 222.Such as shown in Figure 10, the first half relative movement region " E " of peeling process and the later half relative movement region " F " of peeling process can be set.To the setting in region, by above-mentioned configuration part, first area 114, operator can set arbitrarily.Such as, with divesting in strip process (peeling process) that sword 222,223 carries out, can divide with time zone and terminating to peeling from peeling.Such as, can be started the first term area (such as E region) that reasonable time is set to strip process (peeling process) moment from strip process (peeling process), be set to F region by after this.About the appropriate time of the first term area in the moment from strip process (peeling process), according to the specification of wire processing apparatus 100, the time be suitable for can be set as, such as 0.1 second, 0.2 second, 0.3 second, 0.5 second etc.In addition, being not limited to this, can be also multiple time zone by terminating Further Division to peeling from peeling.In addition, operator can set the second abnormality juding region to covered electric cable 150 and the relative movement region divesting sword 222.In this case, the second abnormality juding region can for be selected from the multiple regions preset by operator.

(test example 5 (incision process))

Figure 11 illustrate represent carry out cut process when detection waveform figure.In the example shown in Figure 11, divesting in the closed first half moving area " C " of sword 222, detection waveform does not become large, but in later half moving area " D ", detection waveform becomes large.Can this is presumably because and finally divest in incision process the cause that sword 222 contacts with heart yearn 152.In this case, as shown in figure 12, have on covered electric cable 150, on the position of carrying out incision process, heart yearn 152 creates the possibility of slight damage 156.In this case, according to purposes, there is heart yearn 152 and have any damage namely by as underproof situation.But, also there is the purposes allowing heart yearn 152 to have slight damage.Therefore, the time (divesting the time that sword 222 contacts with heart yearn 152) that detection waveform becomes large can be considered further, or whether occur " contact " etc. in peeling process after this, judge the whether qualified of covered electric cable 150.Thereby, it is possible to suitably to judge that according to the purposes of covered electric cable 150 the whether qualified mode cutting process constructs determination processing.

(test example 6 (incision process))

Figure 13 illustrates and represents the figure of the detection waveform of carrying out when cutting process.In example as shown in fig. 13 that, from divesting the midway of the closed first half moving area " C " of sword 222, detection waveform becomes large, and the detection waveform of later half moving area " D " also becomes large.Therefore, can think that divesting sword 222 in the initial period of incision process contacts with heart yearn 152, then continues " contact " during incision process.In this case, as shown in figure 14, can think at covered electric cable 150, heart yearn 152 creates deep lesions.Such as, when heart yearn 152 is formed by many fine rules gatherings, as shown in figure 14, likely several fine rules are cut off.In this case, be regarded as in most of purposes defective.

(test example 7 (peeling process))

Figure 15 illustrates the figure of the detection waveform represented when carrying out peeling process.In example as shown in figure 15, in the relative movement region " E " of the first half of peeling process, detection waveform does not become large, and in the later half relative movement region " F " of peeling process, detection waveform becomes large.That is, the distance divested between sword 222 and covered electric cable 150 can be thought, but divest sword 222 and " contacted " with heart yearn 152.Thus, as shown in figure 16, likely bending at the end heart yearn 152 of covered electric cable 150, contacting with heart yearn 152 by divesting sword 222 time here divesting sword 222.In addition, as shown in figure 17, likely in the end of covered electric cable 150, divest sword 222 by time divest sword 222 and contact with heart yearn 152, damage is caused to the end of the heart yearn 152 exposed.

In this case, the damage that there is heart yearn 152 in strict purposes is regarded as underproof situation, but for the damage of heart yearn 152, also there is the purposes that processed covered electric cable 150 allows for qualified product.And then, thinner division can be set for divesting the sword 222 relative movement region with covered electric cable 150, considering and which position in relative movement region come in contact thus carries out whether qualifiedly judging.

(test example 8 (peeling process))

Figure 18 illustrates the figure of detection waveform when carrying out peeling process.In the example shown in Figure 18, in the relative movement region " E " of the first half of peeling process, detection waveform becomes large, and in the later half relative movement region " F " of peeling process, detection waveform does not become large.That is, divesting sword 222 near with the distance of covered electric cable 150, but divest sword 222 and heart yearn 152 " contact ", leaving covered electric cable 150 for " contact " when divesting sword 222.Thus, as shown in figure 12, likely in incision process, divest sword 222 and contact with heart yearn 152, then divest sword 222 and do not carry out peeling process contiguously with heart yearn 152.In this case, the possibility that the damage of generation is slight on heart yearn 152 is high, and according to purposes, processed covered electric cable 150 can allow for qualified product.In this case, and then, for divesting the relative movement region of sword 222 with covered electric cable 150, thinner division can be set, judge with on which position in the relative movement region of covered electric cable 150 to occur " contact " divesting sword 222 meticulously, thus carry out whether qualifiedly judging.

(test example 9 (peeling process))

Figure 19 illustrates the figure of the detection waveform represented when carrying out peeling process.In example as shown in figure 19, in the relative movement region " E " of the first half of peeling process, detection waveform becomes large, and in the later half relative movement region " F " of peeling process after this, detection waveform continues to become large.That is, may represent that the distance divesting sword 222 and covered electric cable 150 is near, but divest sword 222 and heart yearn 152 " contact ", during peeling process, then divest sword 222 continue with covered electric cable 150 " contact ".Thus, as shown in figure 20, in incision process, likely divest sword 222 and contact with heart yearn 152, carry out peeling process while the fine rule 152a then in pull-out heart yearn 152, or likely damage is caused to the entirety of the heart yearn 152 exposed.In this case, can think that the damage caused on heart yearn 152 is comparatively large, in most purposes, processed covered electric cable 150 should be judged to be defective.

(electric wire condition detection method)

Like this, this wire processing apparatus 100 (electric wire condition detection method) is described above, has blade edge position check processing, high-frequency signal processes, input process and the first electric wire state detection process.

Here, blade edge position check processing is to by blade driving mechanism 105, blade 104 position of movement is detected.Process occurs high-frequency signal is on heart yearn 152, produce high-frequency signal across the insulator 154 of covered electric cable 150.Input process detects the high-frequency signal (signal of telecommunication) produced on heart yearn 152.First electric wire state detection process is position (be in other words exactly state, opening and closing amount) based on the blade 104 detected by blade edge position check processing and the high-frequency signal that detected by input process, detects (such as test example 1 ~ 6) the state of covered electric cable 150.

According to the electric wire condition detection method of described wire processing apparatus 100, based on the position of blade 104 (state, opening and closing amount) and the high-frequency signal produced on heart yearn 152, the state of covered electric cable 150 can be detected (detect, judge).Therefore, it is possible to more suitably hold the state of processed covered electric cable 150.

In this case, as mentioned above, also can comprise following process, namely based on the size of the high-frequency signal detected by input process, the heart yearn 152 of covered electric cable 150 be detected with " contact " of blade 104.In addition, also the first abnormality juding region can be set in the moving area of blade 104 movement.Individually can set in described first abnormality juding region and cut off process and incision process.Such as, multiple region (be " A ", " B " in the test example 1 ~ 3 about cut-out process, be " C ", " D " in the test example 4 ~ 6 about incision process) is preset.

In this case, the process whether blade edge position when detecting " contact " is judged in the first abnormality juding region can also be comprised.According to this determination processing, when " contact " being detected, as long as determine whether predetermined region in the multiple regions set in moving area, and need not detect with or without " contact " all the time to the movement of blade, electric wire process can be made to be judged to be that abnormal process is simple.Like this, by setting the first abnormality juding region at the moving area of blade 104 movement, electric wire process can be made to be judged to be that abnormal process is simple.In addition, by setting multiple region at the moving area of blade 104 movement, to the judgement that each region contacts, also can shorten and judging the desired time.

In addition, also can be included in when detecting " contact " in predetermined first abnormality juding region in moving area, this electric wire process is judged to be abnormal process.Thus, such as, as above-mentioned test example 2 (see Fig. 5), in the first half of the moving area of cutting edge 221, when " contact " being detected in predetermined region A, electric wire process can be detected as "abnormal".Like this, by pre-determining region in moving area, and when " contact " being detected in this predetermined region, electric wire process being detected as "abnormal", the whether qualified of electric wire process can being judged simply and reliably with few data volume.

In addition, also can be included in the Zone Full set in moving area when " contact " not detected, this electric wire process is judged to be the process into exception.Such as, in suitable cut-out process, necessarily can detect " contact ".In this case, when " contact " not detected in the Zone Full set in moving area, this cut-out process can be judged to be "abnormal".Specifically, as above-mentioned test example 3 (see Fig. 6), when " contact " not detected in the Zone Full set in the moving area of cutting edge 221, electric wire process can be detected as "abnormal".

In addition, in electric wire process, blade 104 (each blade 221,222,223) is by the cutting edge shape with central portion depression, and the situation that a pair blade that this depression is oppositely disposed is formed is more.According to described cutting edge shape, can at the depression induction electric wire of blade 104 central portion, can at the central portion process electric wire of this blade 104, therefore, it is possible to realize more stable electric wire process.Blade driving mechanism 105 ground drives a pair blade 104, makes to close when opening during a pair blade 104.In this case, the interval that the first abnormality juding region can be set in the central portion of a pair blade 104 is greater than the region of covered electric cable 150 external diameter.Therefore, can also be included in when " contact " being detected in this abnormality juding region, this electric wire process is judged to be abnormal process.

In this case, such as, when there is the cutting edge shape of central portion depression, also following process can be comprised, namely in moving area the relative first half of covered electric cable 150 direction of advance of blade 104 predetermined region in, when contact being detected, this electric wire process is judged to be exception.Thus, the recess at blade central portion can not can be responded to electric wire, and be detected as "abnormal" in the situation that this blade central portion can not process electric wire.

In addition, wire processing apparatus 100 possesses covered electric cable driving mechanism 116F, 116R, this covered electric cable driving mechanism 116F, 116R make covered electric cable 150 and blade 104 along the length direction relative movement of covered electric cable 150, leave blade 104 (be in other words exactly make the cable holder 102 of maintenance covered electric cable 150 and blade 104 away from) to make the covered electric cable 150 kept by cable holder 102.Described wire processing apparatus can perform following strip process, namely make to divest under the state that sword 222,223 cuts the insulator 154 of the covered electric cable 150 kept by cable holder 102, make this covered electric cable 150 and divest the length direction relative movement of sword 222,223 along this covered electric cable 150, thus divesting insulator 154.Electric wire condition detection method can also comprise the second electric wire state detection process in this strip process, this the second electric wire state detection process is based on the covered electric cable 150 of movement and divest the relative position (distance) of sword 222,223 by covered electric cable driving mechanism 116F, 116R, and the signal of telecommunication to be detected by input process (high-frequency signal that heart yearn 152 produces), the state of covered electric cable 150 is detected.

In this case, the second abnormality juding region can be set to covered electric cable 150 and the relative movement region divesting sword 222.Such as, multiple region (" E ", " F " such as, in test example 7 ~ 9) can be preset to covered electric cable 150 and the relative movement region divesting sword 222.Now, the second abnormality juding region can be selected from the plurality of region by operator.Like this, by setting the second abnormality juding region to covered electric cable 150 and the relative movement region divesting sword 222, above-mentioned defective judgement can be made to simplify.

(wire processing apparatus 100A)

In addition, in the present embodiment, high frequency voltage is applied to blade 104, make electrode 242,244 otherwise close to covered electric cable 150 (heart yearn 152).Figure 21 represents the wire processing apparatus 100A of other execution mode.In the execution mode that Figure 21 represents, high frequency voltage is applied to the electrode 242,244 close to covered electric cable 150 (heart yearn 152), divest sword 222,223 Received signal strength by F side and R side.The structure of receiver side can insulate for F side tool sword 222 and R side tool sword 223 in this case.Cutting edge 221 can be made to be set to the other system different with R side tool sword 223 from F side tool sword 222, cutting edge 221 also can be made to be electrically connected with any one in F side tool sword 222 and R side tool sword 223.In illustrative example, cutting edge 221 and F side divest sword 222 conducting, but cutting edge 221 and R side divest sword 223 insulate.

Figure 22 is the circuit diagram (equivalent circuit diagram) representing that wire processing apparatus 100A detects the high-frequency signal (signal of telecommunication) produced on heart yearn 152.In the present embodiment, high frequency electric source 240 pairs of electrodes 242 apply the high frequency voltage being controlled as constant voltage.In circuit diagram as shown in figure 22, electric capacity C1 represents the space electric capacity between blade 104 and electrode 242.Electric capacity C2 represents the electric capacity between heart yearn 152 and electrode 242.Switch S 1 represents the action of blade 104 relative to the insulator 154 of covered electric cable 150.The i.e. state opened of switch S 1, represent and be separated with insulator 154 between blade 104 and heart yearn 152, blade 104 and heart yearn 152 be not for contact.In addition, the state that switch S 1 is closed, represents that blade 104 contacts with heart yearn 152.Position in Figure 22 represented by " G " is expressed as the position be electrically connected with machine ground connection (reference potential).

If blade 104 (cutting edge 221 or divest sword 222) contacts with heart yearn 152, then Figure 22 breaker in middle S1 is closure state, and the voltage level variation that blade 104 produces is large.In the present embodiment, signal detector 110 can based on the voltage level produced on blade 104, detects contact to blade 104 and heart yearn 152/do not contact.

In the mode (Fig. 1 (Fig. 3) and Figure 21 (Figure 22)) of the constant voltage source 240 described in using, by the contact of blade 104 with heart yearn 152, blade 104 changes with the resultant impedance of electrode 242,244.Therefore, the voltage level detected by signal detector 110 increases.In addition, in this case, can the circuit of F side and R side side by side, as shown in Figures 1 and 3, can be made up of a constant pressure source.In addition, as high frequency electric source, be not limited to constant voltage source 240, also can use constant-current supply.Citing below represents the situation using constant-current supply.Here, even if refer to, " constant-current supply " is set as that output current is also remained the power supply of fixing set point by the fluctuation of load.

(wire processing apparatus 100B)

In addition, Figure 23 represents the wire processing apparatus 100B of other execution mode further.In the present embodiment, as high frequency electric source, use the high-frequency constant current source 240B being controlled as constant current.In the execution mode that Figure 23 represents, high frequency voltage is applied to blade 104.In addition, in this case, in the structure of the blade 104 of input high frequency voltage, F side tool sword 222 and R side tool sword 223 can be made to insulate.In addition, cutting edge 221 can be made to be set to the other system different with R side tool sword 223 from F side tool sword 222, cutting edge 221 also can be made to be electrically connected with any one in F side tool sword 222 and R side tool sword 223.In illustrative example, cutting edge 221 and F side divest sword 222 conducting, but cutting edge 221 and R side divest sword 223 insulate.

Figure 24 is the circuit diagram (equivalent circuit diagram) representing that this wire processing apparatus 100B detects the high-frequency signal (signal of telecommunication) produced on heart yearn 152.Position in Figure 24 represented by " G " represents and the position that machine ground connection (reference potential) is electrically connected.In the circuit diagram shown in Figure 24, electric capacity C1 represents the space electric capacity between blade 104 and machine ground connection G (reference potential).Electric capacity C2 represents the electric capacity between heart yearn 152 and machine ground connection G (reference potential).Switch S 1 represents the action of the insulator 154 of the relative covered electric cable 150 of blade 104.That is, the state that switch S 1 is opened, represent and be separated with insulator 154 between blade 104 and heart yearn 152, blade 104 and heart yearn 152 be not for contact.In addition, the state that switch S 1 is closed, represents that blade 104 contacts with heart yearn 152.

In this case, if blade 104 contacts with heart yearn 152 (if switch S 1 closes), then the resultant impedance between blade 104 and machine ground connection G (reference potential) changes.Therefore, the voltage level detected by signal detector 110 reduces.Figure 25 represent about Figure 23 wire processing apparatus 100B divest the position of sword 222 and the relation of detection waveform.As shown in figure 25, in this wire processing apparatus 100B, to blade 104 apply high frequency voltage as input signal (signal of telecommunication) the input signal detection device 110 to signal detector 110.That is, when blade 104 does not contact with heart yearn 152, the voltage level detected by signal detector 110 is high.On the other hand, when blade 104 contacts with heart yearn 152, the voltage level detected by signal detector 110 is very low.Therefore, such as, by setting threshold t1, t2 between voltage level when not contacting and voltage level when contacting, can to the contact of blade 104 and heart yearn 152/do not contact and detect.
