Fig. 7 is the flow chart that the contact condition determination processing of being undertaken by contact condition determination processing portion 50 is shown.
After the contact condition determination processing began, contact condition determination processing portion 50 judged that peeling off unit 12 from electric wire has or not the input of driving ON signal in step S1.In step S1, do not drive the input of ON signal, the then processing of step S1 repeatedly if be judged to be.Imported driving ON signal if peel off unit 12 beginning lift-off processing, then in step S1, be judged to be and driven the input of ON signal, entered into step S2 by electric wire.
In step S2, contact condition determination processing portion 50 obtains two vibration amplitude data of peeling off blade 14A, 14B.For example, till from the input of above-mentioned driving ON signal the time, finishing to lift-off processing during, to sampling from the vibration detecting signal of above-mentioned vibration detecting element 42A, 42B and obtaining the vibration amplitude data.After step S2, enter into step S3.
In step S3, contact condition determination processing portion 50 judges about vibration amplitude data of peeling off blade 14A whether the value of amplitude surpasses the threshold value of regulation.Surpass under the situation of the threshold value of stipulating in the value that is judged to be amplitude, enter into step S4.
In step S4, the vibration amplitude data of blade 14B are peeled off about another by contact condition determination processing portion 50, judge whether the value of amplitude surpasses the threshold value of regulation.Surpass under the situation of the threshold value of stipulating in the value that is judged to be amplitude, turn back to step S1, above-mentioned repeatedly processing.
In step S3, S4, the value that is judged to be amplitude surpasses under the situation of the threshold value of stipulating, enters into step S5.
In step S5, contact condition determination processing portion 50 has been judged to be contact, exports this result of determination.According to result of determination, the demonstration of the meaning of contact is arranged in display part 59.Perhaps, according to result of determination, peel off the signal that unit 12 provides the meaning that stops lift-off processing to electric wire.Thus, peel off unit 12 sides, receive this signal and stop lift-off processing temporarily and get final product at electric wire.
In addition, in step S3 and S4, under the value of the amplitude situation identical, also can enter into any one of processing of branch destination with the threshold value of regulation.
In addition, the processing of step S3 and S4 both can be carried out according to opposite order, perhaps also can walk abreast and carry out.
Herein, the amplitude waveform of the vibration that occurs when being illustrated in lift-off processing describes the preferred setting example of above-mentioned threshold value.
In Fig. 8 and Fig. 9, be illustrated in situation about can normally peel off, promptly in heart yearn Wa, do not produce damage, cut-out etc. and can only remove under the situation that coats Wb time t after lift-off processing begins and the relation of amplitude A (amplitude waveform) well.Amplitude waveform when damage has taken place in heart yearn Wa when Figure 10～Figure 12 is illustrated in lift-off processing, amplitude waveform when peeling off blade 14A, 14B when Figure 13 is illustrated in lift-off processing heart yearn Wa being bitten, amplitude waveform when heart yearn Wa partly ruptured when Figure 14 was illustrated in lift-off processing, the amplitude waveform when heart yearn Wa ruptured fully when Figure 15 was illustrated in lift-off processing.In addition, in each figure, with dashed lines is enclosed in peels off the waveform portion of observing when blade 14A, 14B are cut into coating Wb, is enclosed in the waveform portion of observing when peeling off blade 14A, 14B contact or being cut into heart yearn Wa with double dot dash line.In addition, Figure 16 is cut into the figure that the waveform portion observed when coating Wb is amplified with peel off blade 14A, 14B in Fig. 9 in time shaft.Figure 17 will peel off the figure that the waveform portion observed when blade 14A, 14B are cut into heart yearn Wa is amplified in time shaft in Figure 14.Figure 18 will peel off the figure that the waveform portion observed when blade 14A, 14B are cut into heart yearn Wa is amplified in time shaft in Figure 15.

Especially, be cut into as being appreciated that from above-mentioned each figure peeling off blade 14A, 14B that amplitude also becomes big when coating Wb.But, when peeling off blade 14A, 14B contact or being cut into heart yearn Wa, observe bigger amplitude.That is, as can be known in the maximum of the amplitude of peeling off blade 14A, 14B contact or observing when being cut into heart yearn Wa greater than peeling off the maximum that blade 14A, 14B are cut into the amplitude of observing when coating Wb.
Therefore, as can be known as above-mentioned threshold value, be preferably set to greater than peeling off the peaked value that blade 14A, 14B are cut into the amplitude that detects when coating Wb.
Because threshold value in fact as described above is subjected to heart yearn Wa, coats about the material of the material of Wb, shape, blade 14A, 14B, shape etc., so can experimental ground, empirical the setting.
According to the heart yearn contact detecting apparatus, electric wire lift-off processing device, heart yearn contact detecting method and the heart yearn contact detection program that constitute as mentioned above, contact with heart yearn Wa if peel off blade 14A, 14B, then the amplitude of the vibration that detects by vibration detecting element 42A, 42B becomes big.Therefore, when the amplitude of the vibration that detects has surpassed the threshold value of regulation, be judged to be to exist and peel off contacting of blade 14A, 14B and heart yearn Wa, thereby can simply easily detect their contact.
Especially also has following advantage: under the situation of conventional art, need make and peel off blade and other insulation, but in the present embodiment, can not need such insulation countermeasure.
In addition, because vibration detecting element 42A, 42B are to be mounted with peeling off the contacted state of blade 14A, 14B, so reliably be transferred to vibration detecting element 42A, 42B with the elastic wave that contacting of heart yearn Wa produces via peeling off blade 14A, 14B owing to peeling off blade 14A, 14B.Therefore, can detect heart yearn Wa more reliably and peel off contacting of blade 14A, 14B.
But, also only in peeling off blade 14A, 14B the vibration detecting element is installed, carry out the judgement that has or not of above-mentioned contact.
(other variation)
In the above-described embodiment, when the amplitude of above-mentioned vibration detecting signal has surpassed the threshold value of regulation, be judged to be to exist and peel off contacting of blade and heart yearn, but be not limited to such example.
That is,, then compare, detect different vibration waves with the situation that they do not contact if peel off blade and heart yearn comes in contact.Therefore, peel off contacting of blade and heart yearn by detecting the special vibration wave that when peeling off the contacting of blade and heart yearn, takes place according to the size of the energy of vibration detecting signal and in the waveform shape at least one, can detecting.For example, detect the example of method for detecting of size that contactless method is based on the energy of vibration detecting signal according to the size of amplitude as mentioned above.The energy of amplitude also can be represented with mean value or effective value in certain interval of vibration wave.In addition, have or not decision condition as contact based on the value of the energy of the such amplitude of expression, except the size of value relatively, can also adopt various conditions.In addition, can be according to the various values of the size of the energy of expression vibration detecting signal, distinctive waveform shape etc., judge have contactless.
