Description

本発明は、例えば信号線のノイズ等を防止するために二本の電線を弛みなく等ピッチで撚り合わせる電線対撚り用バックテンション機構とそれを用いた対撚り線の製造方法に関するものである。   The present invention relates to an electric wire-twisting back tension mechanism that twists two electric wires at an equal pitch without slacking in order to prevent, for example, signal line noise and the like, and a method of manufacturing a twisted wire using the same.

従来、二本の電線を撚り合わせて対撚り線(ツイスト線)を製造するために種々のツイスト線の製造手段が提案されている。例えば、特許文献1には、二本の電線の両端に接続されたコネクタを各受け治具に固定し、中央の従動ギアの電線挿通溝に各電線を挿通し、駆動ギアで従動ギアを回転させて、電線を撚り合わせることが記載されている。   Conventionally, various twisted wire manufacturing means have been proposed in order to manufacture a twisted wire (twisted wire) by twisting two electric wires together. For example, in Patent Document 1, a connector connected to both ends of two electric wires is fixed to each receiving jig, each electric wire is inserted into the electric wire insertion groove of the central driven gear, and the driven gear is rotated by the drive gear. And twisting the wires together is described.

また、特許文献2には、従来例として、二本の電線の一端側の端子を固定部材に固定し、他端側の端子を回転部材に固定して、回転部材を回転させることで、両電線を撚り合わせることが記載され、一実施例として、二本の電線の各一端側をそれぞれ筒状部内で捻りながら駆動ローラで他端側に向けて送り出し、中間部の回転子を捻りと同方向に回転させつつ他端側に移動させることで、両電線を撚り合わせることが記載されている。   Further, in Patent Document 2, as a conventional example, both terminals on one end side of two electric wires are fixed to a fixing member, a terminal on the other end side is fixed to a rotating member, and the rotating member is rotated. As an example, twist one end of each of the two wires inside the cylindrical portion and feed it toward the other end with a driving roller. As an example, the intermediate rotor is the same as twisted. It is described that the two wires are twisted together by moving to the other end side while rotating in the direction.

また、特許文献3には、各一対の電線の各一端を一方の各クランプに固定し、各一対の電線の各他端を他方の各クランプに固定し、他方の各クランプを各シリンダで引っ張り、両端の各クランプを各モータで逆方向に回転させて一対の対撚り線を形成することが記載されている。   Further, in Patent Document 3, each end of each pair of electric wires is fixed to each one clamp, each other end of each pair of electric wires is fixed to each other clamp, and each other clamp is pulled by each cylinder. In addition, it is described that a pair of twisted wires is formed by rotating the clamps at both ends in opposite directions by motors.

また、特許文献4には、各一対の長さの異なる電線を用いて、各電線の一端を一方の共通のクランプに固定し、一対の長い電線と一対の短い電線との他端をそれぞれ別々のクランプに固定し、短い電線側のクランプはレールに沿って進退自在であり、他端の各クランプをモータで回転して長さの異なる各一対の対撚り線を形成することが記載されている。   In Patent Document 4, each pair of wires having different lengths is used, one end of each wire is fixed to one common clamp, and the other ends of the pair of long wires and the pair of short wires are separately provided. It is described that the clamp on the short wire side can be moved forward and backward along the rail, and each pair of the other ends is rotated by a motor to form a pair of twisted wires having different lengths. Yes.

しかしながら、上記従来の特許文献記載の発明にあっては、例えば図7(a)に一例を示す如く、一対の電線61の一端を共通のクランプ62に一括して固定し、一対の電線61の他端を各クランプ63に固定し、共通クランプ62側で各電線61に一括してバックテンション(引張力)をかけた状態で、例えば中間の回転子64を回転させて電線61の対撚りを行う際に、各電線61の切断長さに寸法公差内のばらつきがあるので、長い方の電線611が若干弛んだ状態で対撚りされることで、図7(b)の如く長さ寸法ばらつきを撚り込み部(ツイスト部分)61aで吸収することになり、そのために対撚りのピッチPの精度が低下し、撚り込み部61aはどこを見ても均一な状態であると言い切ることはできなかった。そのため、完成した対撚り線61’の線間ギャップ・特性インピーダンスの測定等を行って品質を保証する必要があった。なお、図7(b)で符号65は、電線61の両端に接続された端子を示す。 However, in the invention described in the above-mentioned conventional patent document, for example, as shown in FIG. 7A, one end of a pair of electric wires 61 is fixed to a common clamp 62 at a time, and The other end is fixed to each clamp 63, and in a state where back tension (tensile force) is collectively applied to each electric wire 61 on the common clamp 62 side, for example, the intermediate rotor 64 is rotated to twist the electric wire 61 in pairs. When performing, there is a variation within the dimensional tolerance in the cutting length of each electric wire 61. Therefore, when the longer electric wire 61 1 is twisted in a slightly slack state, the length dimension as shown in FIG. The variation is absorbed by the twisted portion (twisted portion) 61a, and therefore the accuracy of the pitch P of the twisted pair is lowered, and it can be said that the twisted portion 61a is in a uniform state no matter where you look. There wasn't. Therefore, it is necessary to guarantee the quality by measuring the gap and characteristic impedance of the completed twisted pair 61 '. In addition, the code | symbol 65 in FIG.7 (b) shows the terminal connected to the both ends of the electric wire 61. FIG.

Each clamp 21 in FIG. 4 is provided on each cylindrical wall 22, each cylindrical wall 22, each electric wire insertion groove 23 having an electric wire abutting surface 23 a on the terminal end side, and the end of the electric wire 8 in the electric wire insertion groove. It comprises a clamping part 24 that is clamped by spring biasing, and an L-shaped operating lever 25 in the direction perpendicular to the cylinder wall that opens the clamping part 24 against spring biasing. The clamps 21 are fixed to a common rotating plate 26 in parallel on the left and right, and the rotating plate 26 is connected to a motor 27 and rotates integrally by driving the motor 27. The motor 27 is fixed to the substrate 28 via a short support 29.

図5(a)に、上記電線対撚り用バックテンション機構1を用いた対撚り線の製造方法の一形態を示す如く、切断寸法公差内の長い電線81と短い電線82との前後端が前後の各クランプ2,21で別々に固定され、前側の(他の)電線クランプ21は前後方向の位置ずれなく左右並列に配置され、各電線8の前端位置は前側の各クランプ21で等しく規定され、後側の各クランプ2は各エアシリンダ6(図3)で個別に後方にスライド移動し、後側の各クランプ2に固定された各電線8に個別にバックテンションが付与されて、長い電線81のクランプ2が後方に、短い電線82のクランプ2が前方に離間して位置する。 Figure 5 (a), as shown one embodiment of a method for manufacturing a twisted pair with a back tension mechanism 1 for the wire pair twist, front and rear ends of the long electric wire 81 and the short wire 82 within the cutting tolerances Are fixed separately by the front and rear clamps 2, 21, and the front (other) wire clamps 21 are arranged in parallel on the left and right sides without any positional displacement in the front-rear direction, and the front end positions of the respective wires 8 are the same for each front clamp 21 The rear clamps 2 are individually slid rearward by the air cylinders 6 (FIG. 3), and back tension is individually applied to the electric wires 8 fixed to the rear clamps 2. clamp 2 long wire 81 is rearward, a clamp 2 for short wire 82 is spaced apart forward.

この状態で、例えば各電線8の後側のクランプ2寄りに配置された回転子30が矢印の如く一方向に回転しつつ前側のクランプ21に向けて等速度で移動し、それと同時に前側のクランプ21がモータ27(図4)で回転子30と同方向に同一回転数で回転することで、後側のクランプ2と回転子30との間で電線8が対撚りされる。   In this state, for example, the rotor 30 disposed near the clamp 2 on the rear side of each electric wire 8 moves at a constant speed toward the front clamp 21 while rotating in one direction as indicated by an arrow, and at the same time, the front clamp. When the motor 21 (FIG. 4) 21 rotates at the same rotational speed in the same direction as the rotor 30, the electric wire 8 is twisted between the rear clamp 2 and the rotor 30.

対撚り中に、図5(b)の如く、各電線8の切断公差がバックテンション負荷側(後端部側)の未撚り部8cで吸収され、長い電線81は短い電線82よりも端部余長Lを有することで、各電線8の撚り込み部(ツイスト部)8dのピッチPが均一化されて、撚り込み部8dのどこを見ても均一に綺麗に仕上げられる。 Some twisted pairs, as in FIG. 5 (b), the cutting tolerance of each electrical wire 8 is absorbed by the non-twisted portion 8c of the back tension load side (rear end side), the long wire 81 is also shorter than the wire 82 By having the end surplus length L, the pitch P of the twisted portion (twisted portion) 8d of each electric wire 8 is made uniform, and the twisted portion 8d can be finished evenly and finely anywhere.

ピッチPを作業者が測定するだけで、製品(対撚り線8’)の性能保証が可能となるため、従来行っていた線間ギャップ・特性インピーダンスの測定が不要となる。図5(b)で符号31は、各電線8の前後端に圧着接続された各端子を示す。   Since the performance of the product (twisted wire 8 ') can be guaranteed only by the operator measuring the pitch P, it is not necessary to measure the gap between the wires and the characteristic impedance which has been conventionally performed. In FIG. 5B, reference numeral 31 indicates each terminal crimped to the front and rear ends of each electric wire 8.

図3において、電線8の対撚り加工中は、各電線8の長さが短縮されるが、バックテンション用の各エアシリンダ6のエア圧をエアレギュレータで管理(制御)することで、エア圧でバックテンション値(N)を制御することができる。エアシリンダ6のロッド6aは伸長せず、エア圧でバックテンション値が管理される。電線の線径や種類によって予め決められているバックテンション値になるようにエア圧をかけ、規定のエア圧に達したところで調整が完了する。   In FIG. 3, the length of each electric wire 8 is shortened during the twisting process of the electric wires 8, but the air pressure of each air cylinder 6 for back tension is controlled (controlled) by an air regulator. Thus, the back tension value (N) can be controlled. The rod 6a of the air cylinder 6 does not extend, and the back tension value is managed by the air pressure. Air pressure is applied so that the back tension value determined in advance according to the wire diameter and type of the wire is reached, and the adjustment is completed when the specified air pressure is reached.

電線8の対撚り加工後は、図1の如くエアシリンダ6を最伸長させ、図2の如く各クランプ2の挟持を解除することで、対撚り線8’を各クランプ2から取り出し可能となる。クランプ2の解除は図1の短いエアシリンダ16を伸長させて操作レバー13を前進させることで自動的に行うことができる。   After the wire 8 is twisted, the air cylinder 6 is extended as shown in FIG. 1 and the clamps 2 are released as shown in FIG. . The clamp 2 can be released automatically by extending the short air cylinder 16 shown in FIG.

図6は、上記電線対撚り用バックテンション機構1を適用した対撚り線の製造装置32の一例を示すものである。   FIG. 6 shows an example of a twisted wire manufacturing apparatus 32 to which the wire-twisting back tension mechanism 1 is applied.

バックテンション機構1は一方(後側)の間欠回転体33の周方向の等間隔の三面に等配に設けられている。図6で、符号2は各電線クランプ、16は各解除用シリンダ、6は各バックテンション用シリンダ、3は各可動基板、5は共通固定基板をそれぞれ示す。三面は三つの共通固定基板5で構成されている。   The back tension mechanism 1 is equally provided on three circumferentially equidistant surfaces of one (rear) intermittent rotating body 33. In FIG. 6, reference numeral 2 denotes each electric wire clamp, 16 denotes each release cylinder, 6 denotes each back tension cylinder, 3 denotes each movable substrate, and 5 denotes a common fixed substrate. The three surfaces are composed of three common fixed substrates 5.

他方(前側)の間欠回転体34の周方向の三面には図4の各一対の電線クランプ(他の電線クランプ)21と共通モータ27が等配に設けられている。三面は三枚の基板28で構成されている。各間欠回転体33,34は各支柱35,36に回動自在に軸支され、間欠駆動手段(例えばエアシリンダ37とトルクブレーキ38)で1/3周ずつ同時に回転する。各間欠回転体33,34の手前側の面が電線セット面5,28、下側の面が電線対撚り面52,282、奥側の面が対撚り線払出し面53,283である。 A pair of electric wire clamps (other electric wire clamps) 21 and a common motor 27 in FIG. 4 are provided at equal intervals on three surfaces in the circumferential direction of the other (front side) intermittent rotating body 34. The three surfaces are composed of three substrates 28. The intermittent rotators 33 and 34 are pivotally supported by the support columns 35 and 36, and are rotated simultaneously by 1/3 round by intermittent drive means (for example, an air cylinder 37 and a torque brake 38). The front surface of each intermittently rotating body 33, 34 is the electric wire set surface 5, 28, the lower surface is the electric wire twisted surface 5 2 , 28 2 , and the rear surface is the twisted wire feeding surface 5 3 , 28 3. It is.

電線セット面5,28において一対の電線8(図3,図4)が前後の各クランプ2,21で固定されて水平なシリンダ6でバックテンションを付与され、下側の電線対撚り面52,282において、図5(a)の如く周上の一部を切欠開口されて切欠開口部30aに対向して対撚り棒30bを有する回転子30が垂直なエアシリンダ(図示せず)で上昇して一対の電線8にセットされて(各電線8が環状の回転子30内に挿通されて)、回転子30とモータ27との同時回転で各電線8が対撚りされ、払出し面53,283において、対撚り線8’(図5(b))の前後両端が自動テープ巻きされて、完成した対撚り線が払い出される。このサイクルが自動で繰り返されて対撚り線8’が効率良く生産される。 A pair of electric wires 8 (FIGS. 3 and 4) are fixed to the front and rear clamps 2 and 21 on the electric wire setting surfaces 5 and 28, and back tension is applied by the horizontal cylinder 6, and the lower electric wire pair twisting surface 5 2. , 28 2 , a rotor 30 having a pair of twisted rods 30b that is partially opened on the circumference and opposed to the notch opening 30a as shown in FIG. 5A is a vertical air cylinder (not shown). Ascended and set on the pair of electric wires 8 (each electric wire 8 is inserted into the annular rotor 30), and the electric wires 8 are twisted together by the simultaneous rotation of the rotor 30 and the motor 27, and the payout surface 5 3 and 28 3 , the front and rear ends of the twisted pair wire 8 ′ (FIG. 5B) are automatically tape-wound, and the completed twisted wire is delivered. This cycle is automatically repeated to produce the twisted wire 8 'efficiently.

なお、上記実施形態においては、回転子30を用いた例で説明したが、例えば回転子30を用いずに、一対の電線8の一端を図3の各クランプ2で固定し、一対の電線8の他端を図4の各クランプ21で固定した状態で、図4のクランプ21をモータ27で回転させることで、一方のクランプ2との間で電線8を対撚りすることも可能である。図4のクランプ21は一例であり、各電線8を別々に挟持固定させてモータ27で回転させるものであれば、形状や構成は適宜設定可能である。   In the embodiment described above, the example using the rotor 30 has been described. However, for example, without using the rotor 30, one end of the pair of electric wires 8 is fixed by the clamps 2 in FIG. It is also possible to twist the electric wire 8 between one clamp 2 by rotating the clamp 21 in FIG. The clamp 21 in FIG. 4 is an example, and the shape and configuration can be appropriately set as long as the electric wires 8 are separately clamped and rotated by the motor 27.

また、図3の各クランプ2と各シリンダ6,16と各基板3,5とで成るクランプ組立体すなわちバックテンション機構1をモータ(図示せず)で回転させることも可能であり、その場合は、図4のクランプ21は各電線8を一括クランプする共通クランプとすることも可能である。また、クランプ側にモータ21を用いずに、中間の回転子30のみを回転させることで、電線8を前後の各クランプ2,21の間で対撚りすることも可能である。また、図3の各クランプ2は一例であり、各電線8を別々に挟持固定させるものであれば、形状や構成は適宜設定可能である。   In addition, it is possible to rotate the clamp assembly, that is, the back tension mechanism 1 composed of each clamp 2, each cylinder 6, 16 and each substrate 3, 5 of FIG. 3 with a motor (not shown). 4 can be a common clamp that collectively clamps the electric wires 8. Moreover, it is also possible to twist the electric wire 8 between the front and rear clamps 2 and 21 by rotating only the intermediate rotor 30 without using the motor 21 on the clamp side. Moreover, each clamp 2 of FIG. 3 is an example, and if it clamps and fixes each electric wire 8 separately, a shape and a structure can be set suitably.

また、図1において、バックテンション用のエアシリンダ6のシリンダ本体6bを可動基板3の前端側に連結し、同じくロッド6aを共通固定基板5の後端側に連結することも可能である。要は、エアシリンダ6は各可動基板3と共通固定基板5とを連結するものであればよい。   In FIG. 1, the cylinder body 6 b of the back tension air cylinder 6 can be connected to the front end side of the movable substrate 3, and the rod 6 a can be connected to the rear end side of the common fixed substrate 5. In short, the air cylinder 6 only needs to connect each movable substrate 3 and the common fixed substrate 5.

本発明に係る電線対撚り用バックテンション機構とそれを用いた対撚り線の製造方法は、例えば自動車のノイズ防止用の信号線等に適用する対撚り線の撚り込み部を弛み(緩み)なく等ピッチで形成して対撚り線の性能を高めるために利用することができる。   The wire-twisting back tension mechanism according to the present invention and the method of manufacturing a twisted wire using the same do not loosen (slack) the twisted portion of the twisted wire applied to, for example, a signal wire for preventing noise of an automobile. It can be used to increase the performance of the twisted wire by forming at an equal pitch.
