- by detecting the presence or absence of “contact” by dividing into areas as described above it is possible to accurately determine the state of the covered electric wire 150 in the electric wire processing while suppressing the amount of data.
- the electric wire processing apparatus 100 can perform cutting processing and strip processing once or more per second, and is operated at a high speed. For this reason, it is necessary to perform quality determination of each electric wire process in a short time. In such a case, it is desirable to reduce the amount of data required for pass / fail determination as long as accurate pass / fail determination can be realized.

- the voltage level of the electrode 242 is high when the pair of cutting blades 221 are separated (the cutting blade 221 is not sufficiently closed). For this reason, for example, as shown in FIG. 6, there is a possibility that the covered electric wire 150 is cut in a state shifted from the center of the blade with respect to the cutting blade 221 having a depressed center.
- FIG. 7 shows the relationship between the position (state, opening / closing amount) of the cutting blade 221 detected by the blade position detector 106 and the high-frequency signal (signal waveform W0) detected by the signal detector 110 in the cutting process.

- the strip blade 222 cuts into the insulator 154 of the covered electric wire 150 but does not contact the core wire 152. That is, as shown in FIG. 9, the detection waveform does not increase in the operation of closing the strip blade 222 and cutting into the insulator 154. Strictly speaking, since the thickness of the insulator 154 is changed by the cutting process, the detected waveform may be slightly increased as the degree of electrostatic coupling is changed. However, even in such a case, the detected waveform does not clearly increase as in the case of contact.
- a plurality of areas for determining “contact” may be set in advance for the moving region in which the strip blade 222 moves.

In this process, the insulator 154 is peeled off from the end 150F.
- the distance between the strip blade 222 and the core wire 152 is slightly increased. If the stripping process is properly performed in the most ideal state, the strip blade 222 does not contact the core wire 152 at all. For this reason, as shown in FIG. 10, in the operation of relatively moving the strip blade 222 and the covered electric wire 150 along the longitudinal direction of the covered electric wire 150, the detected waveform does not increase.

- the detection waveform is not large in the first movement region “C” where the strip blade 222 is closed, but the detection waveform is large in the second movement region “D”. This is considered to be because the strip blade 222 contacts the core wire 152 at the end of the cutting process.
- the covered electric wire 150 may have a slight flaw 156 on the core wire 152 at the site where the cutting process has been performed. In this case, depending on the application, any scratch on the core wire 152 may be regarded as defective. However, there are applications in which slight scratches on the core wire 152 are allowed.
- the quality of the covered electric wire 150 is determined by further taking into consideration the time when the detected waveform becomes large (the time when the strip blade 222 contacts the core wire 152) and the presence or absence of “contact” in the subsequent peeling process. Also good. Thereby, a determination process can be constructed so that the quality of the cutting process can be appropriately determined according to the application of the covered electric wire 150.

かかる切断処理において、例えば、刃104(ここでは、切断刃221)が移動する移動領域に対して、「接触」を判定する複数の区域を予め設定してもよい。例えば、切断処理では、中央が窪んだ一対の切断刃221a、221bが用いられる。この場合、図4に示すように、一対の切断刃221a、221bが開いた状態から、中央が窪んだ一対の切断刃221a、221bの対向距離(中央が窪んだ一対の切断刃221で形成される空間の内接円の直径)が、被覆電線150の外径に相当する距離になるまでの、一対の切断刃221a、221bの移動領域を「A」とし、当該位置(被覆電線150の外径に相当する対向距離)から一対の切断刃221a、221bが完全に閉じるまでの移動領域を「B」とする。このような区域の設定は、上述した第1区域設定部114によって、作業者が任意に設定できる。この場合、例えば、作業者は、切断刃221が閉じる前半の移動領域「A」を、第1異常判定区域として選択するとよい。 ≪Section A, B≫
In such a cutting process, for example, a plurality of areas for determining “contact” may be set in advance with respect to a moving region in which the blade 104 (here, the cutting blade 221) moves. For example, in the cutting process, a pair of
この電線処理装置100は、刃位置検出器106によって検出された切断刃221の位置(状態、開閉量)と、信号検出器110によって検出された高周波信号(信号波形W0)とに基づいて、切断処理における被覆電線150の状態を検出することができる。図5は、刃位置検出器106に検出された切断刃221の位置(状態、開閉量)と、信号検出器110によって検出された高周波信号(信号波形W0)との関係を示している。図5では、一対の切断刃221が離れている状態(切断刃221が十分に閉じていない状態)において、電極242の電圧レベルが高くなっている。このため、例えば、図6に示すように、中央が窪んだ切断刃221に対して、被覆電線150が刃の中央からずれた状態で切断された可能性がある。 ≪Detection example 2 (cutting process) ≫
The electric
図7は、さらに切断処理における、刃位置検出器106に検出された切断刃221の位置(状態、開閉量)と、信号検出器110によって検出された高周波信号(信号波形W0)との関係を示している。図7では、切断刃221が全ての位置(切断刃221が開いている状態から閉じ、再度開くまで)において、電極242の電圧レベルが凡そ変化せず高くなっていない。適切な切断処理では、少なくとも1回は接触が検出されるが、図7の検出例では、芯線152と切断刃221との接触が一度も検出されていない。このため、例えば、図8に示すように、被覆電線150が切断刃221の切断領域からずれて配置され、この状態で切断動作が生じた可能性や、信号検出器110や芯線傷センサの故障の可能性などが考慮されうる。図7に示すような波形が検出された場合には、電線処理装置100が停止するように、電線処理装置100を構成してもよい。電線処理装置100を停止することによって、作業者は図7に示すような波形が検出された原因を調査することができる。 ≪Detection example 3 (cutting process) ≫
FIG. 7 shows the relationship between the position (state, opening / closing amount) of the
次に、ストリップ処理における検出例を説明する。ここでは、F側のストリップ処理を例に挙げて説明するが、R側のストリップ処理も同様である。 ≪Strip processing (cutting and peeling) ≫
Next, a detection example in strip processing will be described. Here, the F-side strip process will be described as an example, but the R-side strip process is the same.
図9は、上述した切込処理(ストリップ処理中の切込処理)でのストリップ刃222(図1参照)の位置(状態、開閉量)と、信号検出器110によって検出される検出波形(高周波信号(信号波形W0))を示している。図10は、ストリップ処理における上述した皮剥処理での、被覆電線150とストリップ刃222との相対位置と、信号検出器110によって検出される検出波形を示している。図9と図10は、それぞれ適切なストリップ処理が行なわれた場合の検出波形のパターンを例示している。 << Detection Example 4 (Strip Processing) >>
FIG. 9 shows the position (state, opening / closing amount) of the strip blade 222 (see FIG. 1) in the above-described cutting process (the cutting process during the strip process), and the detected waveform (high frequency) detected by the
切込処理では、ストリップ刃222が閉じて、被覆電線150の絶縁体154に切り込む。この実施形態では、ストリップ刃222は、刃の中央部が窪んでいる。切込処理において、ストリップ刃222は、図9に示すように、一度深く閉じる。この際、ストリップ刃222は、刃の中央部が窪んだ部位によって、芯線152(図2参照)を残し、絶縁体154に切り込む。次に、ストリップ刃222は少し開く。これにより、ストリップ刃222は、絶縁体154に切り込まれた状態において、ストリップ刃222と芯線152との距離が開く。これにより、ストリップ刃222が被覆電線150の延伸方向に沿って移動する皮剥動作において、ストリップ刃222によって芯線152が傷つくのを防止している。 <Cutting process>
In the cutting process, the
皮剥処理は、ストリップ刃222を絶縁体154に切り込ませた状態で、ストリップ刃222と被覆電線150とを被覆電線150の長手方向に沿って相対的に移動させ、被覆電線150のF側の端部150Fから絶縁体154を剥ぐ処理である。ストリップ刃222は、絶縁体154に切り込まれた状態において、ストリップ刃222と芯線152との距離が少し開いている。最も理想的な状態で適切に皮剥処理が行なわれた場合には、ストリップ刃222は、芯線152には全く接触しない。このため、図10に示すように、ストリップ刃222と被覆電線150とを被覆電線150の長手方向に沿って相対的に移動させる動作において、検出波形が大きくならない。 <Peeling treatment>
In the peeling process, the
図11は、切込処理が行なわれた場合の検出波形のパターンを例示している。図11に示す例では、ストリップ刃222が閉じる前半の移動領域「C」では、検出波形が大きくなっていないが、後半の移動領域「D」では、検出波形が大きくなっている。これは、切込処理の最後で、ストリップ刃222が芯線152に接触したためと考えられる。このような場合には、図12に示すように、被覆電線150には、切込処理が行なわれた部位において芯線152に僅かな傷156が生じた可能性がある。この場合、用途によっては、芯線152のいかなる傷であっても不良とされる場合がある。しかしながら、芯線152の僅かな傷が許容されるような用途もある。したがって、検出波形が大きくなった時間(ストリップ刃222が芯線152に接触した時間)や、その後の皮剥処理での「接触」の有無などをさらに勘案して、被覆電線150の良否判定を行なってもよい。これにより、被覆電線150の用途に応じて適切に切込処理の良否が判定されるように判定処理を構築することができる。 ≪Detection example 5 (cutting process) ≫
FIG. 11 exemplifies a detected waveform pattern when the cutting process is performed. In the example shown in FIG. 11, the detection waveform is not large in the first movement region “C” where the
図13は、切込処理が行なわれた場合の検出波形のパターンを例示している。図13に示す例では、ストリップ刃222が閉じる前半の移動領域「C」の途中から検出波形が大きくなっており、後半の移動領域「D」でも検出波形が大きくなっている。このため、切込処理の最初の段階で、ストリップ刃222が芯線152に接触し、その後、切込処理の間、「接触」が継続したと考えられる。この場合、図14に示すように、被覆電線150には、芯線152に深く傷が生じたものと考えられる。例えば、芯線152が、複数の細線をより合わせたより線である場合には、図14に示すように、細線の数本が切断されている可能性がある。この場合、凡そ多くの用途において不良とされる。 ≪Detection example 6 (cutting process) ≫
FIG. 13 illustrates a pattern of the detected waveform when the cutting process is performed. In the example shown in FIG. 13, the detected waveform increases from the middle of the first half of the moving region “C” where the
図15は、皮剥処理が行なわれた場合の検出波形のパターンを例示している。図15に示す例では、皮剥処理の前半の相対移動領域「E」では検出波形が大きくなっておらず、皮剥処理の後半の相対移動領域「F」で検出波形が大きくなっている。つまり、ストリップ刃222と被覆電線150との距離が遠くなったところで、ストリップ刃222と芯線152とが「接触」した考えられる。このことから、図16に示すように、被覆電線150の端において芯線152が曲がっており、ここをストリップ刃222が通過する際にストリップ刃222と芯線152とが接触した可能性がある。また、図17に示すように、被覆電線150の端において、ストリップ刃222が通過する際にストリップ刃222と芯線152とが接触し、露出した芯線152の先端に傷が付いた可能性がある。 ≪Detection example 7 (peeling process) ≫
FIG. 15 shows an example of a detected waveform pattern when the skinning process is performed. In the example shown in FIG. 15, the detection waveform is not large in the relative movement region “E” in the first half of the skinning process, and the detection waveform is large in the relative movement region “F” in the second half of the skinning process. That is, it is considered that the
図18は、皮剥処理が行なわれた場合の検出波形のパターンを例示している。図18に示す例では、皮剥処理の前半の相対移動領域「E」では検出波形が大きくなっており、皮剥処理の後半の相対移動領域「F」では検出波形が大きくなっていない。つまり、ストリップ刃222と被覆電線150との距離が近いところで、ストリップ刃222と芯線152とが「接触」し、ストリップ刃222と被覆電線150とが離れると「非接触」になっている。このことから、図12に示すように、切込処理において、ストリップ刃222が芯線152に接触し、その後、ストリップ刃222と芯線152とが接触せずに、皮剥処理が行なわれた可能性がある。この場合、芯線152に生じた傷は、僅かである可能性が高く、用途によっては処理された被覆電線150は良品として許容されうる。この場合、さらに、ストリップ刃222と被覆電線150との相対移動領域について、区分を細かく設定しておき、ストリップ刃222と被覆電線150との相対移動領域のどの位置で「接触」があったかを細かく判定して、良否判定を行なってもよい。 ≪Detection example 8 (peeling process) ≫
FIG. 18 illustrates a pattern of the detected waveform when the skinning process is performed. In the example shown in FIG. 18, the detected waveform is large in the relative movement region “E” in the first half of the skinning process, and the detected waveform is not large in the relative movement region “F” in the latter half of the skinning process. That is, when the distance between the
図19は、皮剥処理が行なわれた場合の検出波形のパターンを例示している。図19に示す例では、皮剥処理の前半の相対移動領域「E」では検出波形が大きくなっており、その後の皮剥処理の後半の相対移動領域「F」でも継続して検出波形が大きくなっている。つまり、ストリップ刃222と被覆電線150との距離が近いところで、ストリップ刃222と芯線152とが「接触」し、その後、皮剥処理の間、ストリップ刃222と被覆電線150とが継続して「接触」した可能性を示している。このことから、図20に示すように、切込処理において、ストリップ刃222が芯線152に接触し、その後、芯線152中の細線152aを引き出しながら皮剥処理が行なわれた可能性または露出した芯線152が全長において傷がついた可能性がある。この場合、芯線152に生じた傷は大きいと考えられ、多くの用途において、処理された被覆電線150は不良と判定されるべき事象となる。 ≪Detection example 9 (peeling process) ≫
FIG. 19 shows an example of a detected waveform pattern when the peeling process is performed. In the example shown in FIG. 19, the detected waveform is large in the relative movement area “E” in the first half of the peeling process, and the detected waveform is continuously increased in the relative movement area “F” in the latter half of the subsequent peeling process. Yes. That is, when the distance between the
このように、この電線処理装置100(電線状態検出方法)は、上述したように刃位置検出処理と、高周波信号発生処理と、信号検出処理と、第1電線状態検出処理とを有している。 ≪Wire state detection method≫

なお、この実施形態では、刃104に高周波電圧を印加し、電極242、244を別途被覆電線150(芯線152)に近接させている。図21は、他の実施形態に係る電線処理装置100Aを示している。図21に示す実施形態では、被覆電線150(芯線152)に近接した電極242、244に高周波電圧を印加して、F側とR側のストリップ刃222、223で受信している。この場合、受信側の構成は、F側の刃222と、R側の刃223とは絶縁しておくとよい。切断刃221は、F側の刃222とR側の刃223とを別系統にしてもよいし、F側の刃222とR側の刃223の何れか一方に電気的に接続されていてもよい。図示例では、切断刃221とF側のストリップ刃222は導通しているが、切断刃221とR側のストリップ刃223とは絶縁されている。 ≪

図26は、さらに他の実施形態に係る電線処理装置100Cを示している。この実施形態では、高周波電源として、定電流に制御された高周波定電流電源240Bが用いられている。この点、図23に示された電線処理装置100Bと共通している。図26に示す実施形態では、絶縁体154を介して芯線152に近接するように電極242、244が設けられている。高周波定電流電源240Bは、かかる電極242、244に高周波電圧を印加する。この場合、高周波電圧が入力される刃104の構成では、F側の刃222と、R側の刃223とは必ずしも絶縁しておく必要はない。 ≪

図29と図30は、上述した切断処理とストリップ処理(切込処理および皮剥処理)の良否判定を含む、電線処理の処理フローについて一例を示している。この処理フローは、図29に示すように、S1:区域設定(切断)、S2:区域設定(切込)、S3:区域設定(皮剥)、S4:終了条件の設定、S5:切断処理、S6:切込処理、S7:皮剥処理、S8:良否判定処理、S9:終了条件判定、の各処理を有している。以下、各処理を説明する。 ≪Pass / fail judgment processing flow≫
FIG. 29 and FIG. 30 show an example of the processing flow of the electric wire processing including the quality determination of the cutting processing and strip processing (cutting processing and peeling processing) described above. As shown in FIG. 29, the processing flow is as follows: S1: area setting (cutting), S2: area setting (cutting), S3: area setting (peeling), S4: end condition setting, S5: cutting process, S6 : Cutting process, S7: skinning process, S8: pass / fail judgment process, S9: end condition judgment. Hereinafter, each processing will be described.
切断処理に対する区域設定(S1)では、切断処理に対する良否判定を行なうため、切断刃221が移動する移動領域に対して、異常を判定するための区域を設定する。例えば、切断処理においては、図4、図5および図7に示すような区域Aや区域Bを設定するとよい。なお、かかる区域設定は、図示例に限定されない。作業者は、処理対象となる被覆電線150の直径や芯線152の直径(図2参照)などの仕様、切断刃221の形状、および、処理速度などを考慮して、任意に複数の区域を設定することができる。なお、作業者は、切断刃221が移動する移動領域に対して、異常判定区域のみ(例えば、区域Aのみ)を設定してもよい。異常判定区域は、複数設けられていてもよい。また、電線処理装置100は、切断刃221が移動する移動領域に対して予め複数の領域を設定しておき、作業者が、当該複数の領域から異常判定区域を選択するように構成してもよい。 <S1: Zone setting (cutting)>
In the area setting (S1) for the cutting process, an area for determining abnormality is set for the moving region in which the
切込処理に対する区域設定(S2)では、切込処理に対する良否判定を行なうため、ストリップ刃222、223が移動する移動領域に対して、異常を判定するための区域を設定する。例えば、切込処理においては、図9、図11および図13に示すような区域Cや区域Dを設定するとよい。なお、かかる区域設定は、図示例に限定されない。作業者は、処理対象となる被覆電線150の直径や芯線152の直径(図2参照)などの仕様、ストリップ刃222、223の形状、および、処理速度などを考慮して、任意に複数の区域を設定することができる。なお、作業者は、ストリップ刃222、223が移動する移動領域に対して、異常判定区域のみ(例えば、区域Cのみ)を設定してもよい。異常判定区域は、複数設けられていてもよい。また、電線処理装置100は、ストリップ刃222、223が移動する移動領域に対して予め複数の領域を設定しておき、作業者が、当該複数の領域から異常判定区域を選択するように構成してもよい。 <S2: Area setting (cutting)>
In the area setting (S2) for the cutting process, an area for determining an abnormality is set for the moving region in which the
皮剥処理に対する区域設定(S3)では、皮剥処理に対する良否判定を行なうため、被覆電線150とストリップ刃222、223との相対移動領域に対して、異常を判定するための区域を設定する。例えば、皮剥処理においては、図10、図15、図18および図19に示すような区域Eや区域Fを設定するとよい。なお、かかる区域設定は、図示例に限定されない。作業者は、処理対象となる被覆電線150の直径や芯線152の直径(図2参照)などの仕様、ストリップ刃222、223の形状、および、処理速度などを考慮して、任意に複数の区域を設定することができる。なお、作業者は、被覆電線150とストリップ刃222、223との相対移動領域に対して、異常判定区域のみを設定してもよい。異常判定区域は、複数設けられていてもよい。また、電線処理装置100は、被覆電線150とストリップ刃222、223との相対移動領域に対して、予め複数の領域を設定しておき、作業者が、当該複数の領域から異常判定区域を選択するように構成してもよい。 <S3: Area setting (peeling)>
In the area setting (S3) for the skinning process, an area for determining an abnormality is set for the relative movement region between the covered
また、この例では、電線処理について、終了条件が設定されている。終了条件は、被覆電線150について、例えば、処理本数に応じて終了する場合には、終了する処理本数を設定しておくとよい。終了条件は、作業者が所定の条件を任意に設定できるように構成されているとよい。なお、この例では、区域設定から終了条件の設定まで(S1~S4)は、被覆電線150に対する連続した切断処理を開始する際の前処理となる。 <S4: End condition setting>
In this example, an end condition is set for the wire processing. As for the end condition, for the covered
次に、切断処理(S5)、切込処理(S6)、皮剥処理(S7)が順に実行される。すなわち、被覆電線150は、所定量送られて、切断処理(S5)が行なわれ、F側の端部150FとR側の端部150Rのストリップ処理(切込処理S6と皮剥処理S7)が行なわれる。 <S5: Cutting process to S7: Peeling process>
Next, a cutting process (S5), a cutting process (S6), and a peeling process (S7) are performed in order. That is, the covered
良否判定処理(S8)は、切断処理(S5)、切込処理(S6)、皮剥処理(S7)の一連の処理が施された被覆電線150の良否判定を行なう。例えば、図30に示すように、切断処理の良否判定(S21)、切込処理の良否判定(S22)、皮剥処理の良否判定(S23)を行なう。各良否判定(S21~S23)が全て正常である場合「Y」には、処理された被覆電線150は「良品」として扱う。各良否判定(S21~S23)で異常が検出された場合「N」には、処理された被覆電線150を「不良」として、例えば、処理電線を不良品トレイに移す処理(S24)や作業者への通知処理(例えば、警報灯の点灯や警報音の発信など)が行なわれる。 <S8: Pass / Fail Judgment Processing>
In the pass / fail determination process (S8), the pass / fail determination of the covered
終了条件判定(S9)は、S4で設定された終了条件に合致するかを判定する。終了条件に合致した場合「Y」には、電線処理は終了する。終了条件に合致しない場合「N」には、上述した切断処理(S5)~皮剥処理(S7)が連続して繰り返される。 <S9. End condition judgment>
In the end condition determination (S9), it is determined whether the end condition set in S4 is met. If the end condition is met, “Y” ends the wire processing. When the end condition is not met, the above-described cutting process (S5) to peeling process (S7) are repeated continuously when “N” is satisfied.
