Description
本発明は、線材繰出し装置及びそれを備えた巻線装置に関するものである。
The present invention relates to a wire rod feeding device and a wire winding device equipped with the same.
従来、線材を巻回する巻線装置として、ドラム等に巻回されて貯線された線材をドラム等から引き出しつつ巻線するものが知られている。このような巻線装置では、線材の断面積が大きくなると線材の引き出し抵抗が増加するので、ドラム等から線材を引き出しつつ巻線機構に送る線材繰出し装置を備えた巻線装置が知られている(JPH10-303055A参照)。
BACKGROUND ART Conventionally, as a winding device for winding a wire, a device is known that winds a wire that has been wound and stored on a drum or the like while pulling it out from the drum or the like. In such a winding device, the wire drawing resistance increases as the cross-sectional area of the wire increases, so winding devices are known that are equipped with a wire feeding device that draws the wire from a drum or the like and feeds it to the winding mechanism. (Refer to JPH10-303055A).
この線材繰出し装置は、線材を開放可能に挟持する固定チャック装置と、可動チャック装置と、可動チャック装置を固定チャック装置に離接させるアクチュエータと、を備え、アクチュエータにより、線材を挟持した可動チャック装置を、線材を開放させた固定チャック装置に接近させ、固定チャック装置側から線材を繰出す。
This wire rod feeding device includes a fixed chuck device that releasably clamps the wire rod, a movable chuck device, and an actuator that moves the movable chuck device toward and away from the fixed chuck device, and the movable chuck device that clamps the wire rod by the actuator. is brought close to the fixed chuck device with the wire rod released, and the wire rod is fed out from the fixed chuck device side.
線材繰出し装置において、線材の一回の繰出し量を多くすると、繰り出される線材が座屈してしまうという問題がある。このため、JPH10-303055Aに記載の線材繰出し装置では、図11に示すように、繰出し量SLを超える長さを有するチューブ状の線材ガイド2を可動チャック装置3に設け、線材ガイド2が進入可能であって繰出し量SLを超える長さの線材案内路4aを固定チャック装置4に形成している。線材ガイド2に通した状態で線材1を繰出すことにより、太い線材1を座屈させることなく繰出すことができる。
In a wire rod feeding device, if the amount of wire rod fed out at one time is increased, there is a problem that the wire rod being fed out will buckle. For this reason, in the wire rod feeding device described in JPH10-303055A, as shown in FIG. 11, a tube-shaped wire rod guide 2 having a length exceeding the feeding amount SL is provided in the movable chuck device 3, so that the wire rod guide 2 can enter. A wire guide path 4a having a length exceeding the payout amount SL is formed in the fixed chuck device 4. By paying out the wire 1 while passing through the wire guide 2, the thick wire 1 can be paid out without buckling.
しかし、チューブ状の線材ガイド2を可動チャック装置3に設ける上記の線材繰出し装置では、繰出し量SLを超える長さの線材ガイド2が進入可能な線材案内路4aを固定チャック装置4に形成するので、装置を設置するための空間として一回の繰出し量SLの倍を超える長さが少なくとも必要となり、一回の繰出し量が多いと、装置が大型化するという問題がある。
However, in the above wire rod feeding device in which the tubular wire rod guide 2 is provided in the movable chuck device 3, a wire rod guide path 4a into which the wire rod guide 2 having a length exceeding the feeding amount SL can enter is formed in the fixed chuck device 4. As a space for installing the device, at least a length exceeding twice the amount of one payout SL is required, and if the amount of one payout is large, there is a problem that the device becomes large.
また、巻線装置により巻回される線材は、断面が丸型の丸線に限られずに、断面が方形の角線も存在する。断面が長方形の平角線を、断面が円形のチューブ状の線材ガイドに挿通させると、線材ガイドと平角線の間の隙間の存在により、平角線の厚さ方向の座屈を有効に防止できないという問題もある。
Furthermore, the wire rods wound by the winding device are not limited to round wires with a round cross section, but also square wires with a rectangular cross section. When a flat wire with a rectangular cross section is inserted into a tubular wire guide with a circular cross section, buckling in the thickness direction of the flat wire cannot be effectively prevented due to the existence of a gap between the wire guide and the flat wire. There are also problems.
本発明は、装置を大型化させることなく、線材が平角線であっても線材の座屈を防止しつつ繰出すことができる線材繰出し装置及びそれを用いた巻線装置を提供することを目的とする。
An object of the present invention is to provide a wire rod feeding device and a wire winding device using the same, which can feed the wire rod while preventing buckling even if the wire rod is a rectangular wire without increasing the size of the device. shall be.

図4に示すように、エアシリンダ67のロッド67aは、凹部66aに進入すると、凹部66aを通過している平角線11に当接して凹部66aに押し付けることにより、平角線11を挟持して平角線11の移動を禁止する。一方、図2に示すように、ロッド67aは、本体67bに退出すると、凹部66aを通過している平角線11の挟持を解消して、平角線11の移動を許容する。
As shown in FIG. 4, when the rod 67a of the air cylinder 67 enters the recess 66a, it comes into contact with the rectangular wire 11 passing through the recess 66a and presses against the recess 66a. Movement of line 11 is prohibited. On the other hand, as shown in FIG. 2, when the rod 67a retreats into the main body 67b, it releases the clamping of the rectangular wire 11 passing through the recess 66a, allowing the rectangular wire 11 to move.
可動チャック装置63がアングル部材62eを介して横方向移動部材62dに取付けられたアクチュエータ62により、図4に実線矢印で示すように、平角線11を挟持した状態の可動チャック装置63を固定チャック装置61に近づけると、可動チャック装置63に掴まれた平角線11はY軸方向に移動する。このとき、固定チャック装置61が平角線11を開放していれば、平角線11は固定チャック装置61から巻回機構30に向かって長手方向(Y軸方向)に繰出される。
The movable chuck device 63 moves the movable chuck device 63 holding the rectangular wire 11 between the fixed chuck devices by the actuator 62 attached to the lateral moving member 62d via the angle member 62e, as shown by the solid arrow in FIG. 61, the rectangular wire 11 gripped by the movable chuck device 63 moves in the Y-axis direction. At this time, if the fixed chuck device 61 releases the flat wire 11, the flat wire 11 is fed out from the fixed chuck device 61 toward the winding mechanism 30 in the longitudinal direction (Y-axis direction).
その後、固定チャック装置61が平角線11を挟持すると、平角線11の繰出しは停止する。この状態で、可動チャック装置63が平角線11を開放すると、図2に破線矢印で示すように、アクチュエータ62により可動チャック装置63を固定チャック装置61から遠ざけることができる。
Thereafter, when the fixed chuck device 61 clamps the flat wire 11, the feeding of the flat wire 11 is stopped. In this state, when the movable chuck device 63 releases the rectangular wire 11, the actuator 62 can move the movable chuck device 63 away from the fixed chuck device 61, as shown by the broken line arrow in FIG.
可動チャック装置63を固定チャック装置61から遠ざけるとき、即ち、リール側に可動チャック装置63を戻すときに、固定チャック装置61が平角線11を挟持することにより、巻回機構30側に繰出された平角線11が可動チャック装置63とともに移動して戻ることが防止される。
When moving the movable chuck device 63 away from the fixed chuck device 61, that is, when returning the movable chuck device 63 to the reel side, the fixed chuck device 61 clamps the flat wire 11, so that the flat wire 11 is fed out to the winding mechanism 30 side. The rectangular wire 11 is prevented from moving back together with the movable chuck device 63.
リール側に移動した可動チャック装置63により平角線11を再び掴むとともに固定チャック装置61を開放した状態で、図4に示すように、可動チャック装置63を再び固定チャック装置61に向けて移動させることにより、平角線11を再び繰出すことができる。以上の可動チャック装置63及び固定チャック装置61の一連の動作を繰り返すことにより、平角線11を順次繰出すことができる。
With the flat wire 11 gripped again by the movable chuck device 63 that has moved to the reel side and the fixed chuck device 61 released, the movable chuck device 63 is moved again toward the fixed chuck device 61 as shown in FIG. This allows the flat wire 11 to be fed out again. By repeating the above series of operations of the movable chuck device 63 and the fixed chuck device 61, the rectangular wire 11 can be sequentially fed out.

As shown in FIG. 7, the support piece 71 that supports the flat wire 11 includes a rectangular plate-shaped movable guide 72 extending in the X-axis direction and a presser plate 73 attached to the movable guide 72. A pair of insertion holes 72a are formed in the movable guide 72 on both sides in the X-axis direction, into which the pair of support rods 68 are respectively inserted. Attachment holes 72b penetrating in the Z-axis direction are formed further outside the pair of insertion holes 72a, respectively.
可動ガイド72の下面には、平角線11の断面形状よりもわずかに大きな断面を成す凹溝72cがY軸方向に延びて形成される。凹溝72cにY軸方向に延びる平角線11を収容した状態で、可動ガイド72の下面に押さえ板73が取付けられる。押さえ板73には取付孔72bに対向して雌ねじ孔73aが形成され、取付孔72bに挿入された雄ネジ74を螺合させることにより、可動ガイド72に押さえ板73が取付けられる。
On the lower surface of the movable guide 72, a groove 72c having a cross section slightly larger than that of the flat wire 11 is formed extending in the Y-axis direction. A pressing plate 73 is attached to the lower surface of the movable guide 72 with the rectangular wire 11 extending in the Y-axis direction accommodated in the groove 72c. A female threaded hole 73a is formed in the holding plate 73 facing the mounting hole 72b, and the holding plate 73 is attached to the movable guide 72 by screwing a male screw 74 inserted into the mounting hole 72b.
図1~図4に戻って、可動ガイド72は、固定チャック装置61と可動チャック装置63の間の一対の支持ロッド68に複数設けられる。線材繰出し装置60は、固定チャック装置61と可動チャック装置63の間に複数の支持片71を、所定間隔を空けて配置する配置手段を備える。
Returning to FIGS. 1 to 4, a plurality of movable guides 72 are provided on the pair of support rods 68 between the fixed chuck device 61 and the movable chuck device 63. The wire rod feeding device 60 includes an arrangement means for arranging a plurality of support pieces 71 between the fixed chuck device 61 and the movable chuck device 63 at predetermined intervals.
図1及び図3に示すように、本実施形態における配置手段は、複数の支持片71の間のそれぞれに介在された弾性部材であり、具体的にはコイルスプリング76である。コイルスプリング76は、固定壁69と支持片71の間及び可動壁66と支持片71の間にもそれぞれ介在される。隣接する支持片71の間隔は、コイルスプリング76の自然長とばね定数により設定される。本実施形態では、介在された複数のコイルスプリング76は全て同一である。複数のコイルスプリング76が均一な付勢力により隣接する支持片71の間隔を広げようとすることにより、固定チャック装置61と可動チャック装置63の間において複数の支持片71が等分に配置される。つまり、固定チャック装置61と可動チャック装置63の間において、隣接する支持片71の間隔は互いに同じである。具体的には、可動チャック装置63が固定チャック装置61から最も離間している状態において、複数の支持片71が等分に配置される。複数の支持片71が等分に配置されると、固定チャック装置61に対して可動チャック装置63がスムーズに移動することができる。また、介在される各コイルスプリング76が同一である場合には、同一の仕様のコイルスプリング76を用いることができるため、コストを低減させることができる。
As shown in FIGS. 1 and 3, the arrangement means in this embodiment is an elastic member interposed between each of the plurality of support pieces 71, specifically a coil spring 76. The coil spring 76 is also interposed between the fixed wall 69 and the support piece 71 and between the movable wall 66 and the support piece 71, respectively. The distance between adjacent support pieces 71 is determined by the natural length and spring constant of the coil spring 76. In this embodiment, the plurality of interposed coil springs 76 are all the same. Since the plurality of coil springs 76 attempt to widen the distance between adjacent supporting pieces 71 with uniform biasing force, the plurality of supporting pieces 71 are arranged equally between the fixed chuck device 61 and the movable chuck device 63. . That is, between the fixed chuck device 61 and the movable chuck device 63, the spacing between adjacent support pieces 71 is the same. Specifically, in a state where the movable chuck device 63 is the most distant from the fixed chuck device 61, the plurality of support pieces 71 are arranged equally. When the plurality of support pieces 71 are arranged equally, the movable chuck device 63 can move smoothly with respect to the fixed chuck device 61. Furthermore, when the intervening coil springs 76 are the same, the coil springs 76 having the same specifications can be used, so that costs can be reduced.
支持片71の両面には、その中央にコイルスプリング76の端部が進入可能な座繰り穴72dが形成される。図3に示すように、隣接する支持片71が接近した場合には、圧縮されたコイルスプリング76は、隣接する支持片71の座繰り穴72dにわたって収容される。

A reinforcing rod 77 is further provided on the fixed wall 69 attached to the fixed base 29 adjacent to the fixed chuck device 61. The reinforcing rod 77 is provided extending between the fixed chuck device 61 and the movable chuck device 63 and penetrating the movable chuck device 63. The reinforcing rod 77 has a larger diameter than the pair of support rods 68. A hole 66d through which a reinforcing rod 77 passes is formed in the movable wall 66. A cylinder sleeve 66e for ensuring smooth movement of the reinforcing rod 77 is attached to the hole 66d.
図1~図4及び図8に示すように、固定台29には、線材繰出し装置60によりY軸方向に繰出された平角線11がX軸方向に振れることを防止する支持部材54が設けられる。
As shown in FIGS. 1 to 4 and 8, the fixed base 29 is provided with a support member 54 that prevents the rectangular wire 11 fed out in the Y-axis direction by the wire feeding device 60 from swinging in the X-axis direction. .
支持部材54は、固定チャック装置61に対向して固定台29に取付けられる。支持部材54には、Y軸方向に繰出された平角線11が進入する横凹溝54aと、平角線11を挟持する一対の挟持片61b,61cを収容する縦凹溝54bと、が固定チャック装置61に対向する部位に形成される。
The support member 54 is attached to the fixed base 29 facing the fixed chuck device 61. The support member 54 has a horizontal groove 54a into which the rectangular wire 11 fed out in the Y-axis direction enters, and a vertical groove 54b that accommodates a pair of clamping pieces 61b and 61c that clamp the rectangular wire 11. It is formed at a portion facing the device 61.
横凹溝54aにY軸方向に延びる平角線11が進入して収容されることにより、平角線11の長手方向であるY軸方向の繰出しを許容しつつ幅方向であるX軸方向への移動が防止される。
The rectangular wire 11 extending in the Y-axis direction enters and is housed in the horizontal groove 54a, allowing the rectangular wire 11 to be fed out in the Y-axis direction, which is the longitudinal direction, while moving in the X-axis direction, which is the width direction. is prevented.
図1~図4に示すように、固定台29にはガイド部材55が設けられる。ガイド部材55は、平角線11の先端縁が摺接する。本実施形態では、ガイド部材55は、楔状の断面を有する摺接部55aを有する。摺接部55aは、表面(上面)が水平面に対して傾斜して形成され、その表面に最初に折り曲げられた平角線11の先端縁11c(図9C)が摺接する。
As shown in FIGS. 1 to 4, a guide member 55 is provided on the fixed base 29. The guide member 55 is in sliding contact with the tip edge of the flat wire 11 . In this embodiment, the guide member 55 has a sliding contact portion 55a having a wedge-shaped cross section. The sliding contact portion 55a is formed so that its surface (upper surface) is inclined with respect to the horizontal plane, and the tip edge 11c (FIG. 9C) of the first bent flat wire 11 comes into sliding contact with the surface.
摺接部55aの表面に平角線11の先端縁が摺接することにより、平角線11が水平面に対して傾斜するため、平角線11の折り曲げられた部位が繰出された平角線11と干渉することが防止される。
Since the tip edge of the flat wire 11 comes into sliding contact with the surface of the sliding contact portion 55a, the flat wire 11 is inclined with respect to the horizontal plane, so that the bent portion of the flat wire 11 may interfere with the fed-out flat wire 11. is prevented.
次に、巻線装置10の動作について説明する。
Next, the operation of the winding device 10 will be explained.
本実施形態では、線材が、厚さに対して幅が広い平角線11であり、平角線11を幅方向に巻回することにより、トラック形のエッジワイズコイル16(図9及び図10)を得る場合について説明する。
In this embodiment, the wire is a rectangular wire 11 that is wide in relation to its thickness, and by winding the rectangular wire 11 in the width direction, a track-shaped edgewise coil 16 (FIGS. 9 and 10) is formed. Let's explain how to obtain it.
巻線装置10を用いたトラック形のエッジワイズコイルの巻線は、準備工程の後に、巻回機構30により平角線11をシャフト31の周囲に掛け回してU字状に折り曲げる線材折り曲げ工程と、線材繰出し装置60により平角線11を繰出す線材繰出し工程と、を繰り返すことにより行われる。
Winding a track-shaped edgewise coil using the winding device 10 includes, after the preparation step, a wire bending step in which the flat wire 11 is wound around the shaft 31 by the winding mechanism 30 and bent into a U-shape; This is performed by repeating the wire rod feeding step of feeding out the rectangular wire 11 using the wire rod feeding device 60.
これらの動作を以下に説明する。
These operations will be explained below.
<巻線準備工程>
先ず、固定チャック装置61及び可動チャック装置63の双方を開放して、リールから繰出される平角線11を固定チャック装置61及び可動チャック装置63に通過させる。 <Winding preparation process>
First, both the fixedchuck device 61 and the movable chuck device 63 are opened, and the flat wire 11 fed out from the reel is allowed to pass through the fixed chuck device 61 and the movable chuck device 63.
先ず、固定チャック装置61及び可動チャック装置63の双方を開放して、リールから繰出される平角線11を固定チャック装置61及び可動チャック装置63に通過させる。 <Winding preparation process>
First, both the fixed
具体的には、図2に示すように、可動チャック装置63では、エアシリンダ67のロッド67aを本体67bに退出させ、可動壁66の凹部66aに平角線11を通過させる。そして、可動チャック装置63を通過した平角線11を複数の支持片71における凹溝72c(図7)に順次挿通させ、可動チャック装置63から固定チャック装置61に向かう平角線11を複数の支持片71により順次支持させる。
Specifically, as shown in FIG. 2, in the movable chuck device 63, the rod 67a of the air cylinder 67 is withdrawn to the main body 67b, and the rectangular wire 11 is passed through the recess 66a of the movable wall 66. Then, the rectangular wire 11 that has passed through the movable chuck device 63 is sequentially inserted into the grooves 72c (FIG. 7) in the plurality of support pieces 71, and the rectangular wire 11 going from the movable chuck device 63 to the fixed chuck device 61 is inserted into the plurality of support pieces. 71 in order.
そして、固定壁69側における最後の支持片71を通過した平角線11を、固定壁69の凹部69a(図6)に通過させて、図8に示すように、支持部材54の横凹溝54aに通過させる。このとき、図4に示すように、固定チャック装置61の一対の挟持片61bは互いに離間した状態であり、平角線11を一対の挟持片61bの間に通過させる。そして、支持部材54を通過した平角線11を、図1に示すように、巻回機構30におけるシャフト31とベンダ32の間に挿通させる。
Then, the rectangular wire 11 that has passed through the last support piece 71 on the fixed wall 69 side is passed through the recess 69a (FIG. 6) of the fixed wall 69, and as shown in FIG. pass through. At this time, as shown in FIG. 4, the pair of clamping pieces 61b of the fixed chuck device 61 are in a state separated from each other, and the rectangular wire 11 is passed between the pair of clamping pieces 61b. Then, the rectangular wire 11 that has passed through the support member 54 is inserted between the shaft 31 and the bender 32 in the winding mechanism 30, as shown in FIG.
この状態で、固定チャック装置61における一対の挟持片61bを互いに接近させて、その間を通過する平角線11を鉛直方向の上下から挟み込んで、平角線11の移動を禁止する。
In this state, the pair of clamping pieces 61b of the fixed chuck device 61 are brought close to each other, and the rectangular wire 11 passing therebetween is clamped from above and below in the vertical direction, thereby prohibiting movement of the rectangular wire 11.
固定チャック装置61により平角線11を挟持した後には、線材繰出し装置60のアクチュエータ62により、可動チャック装置63を固定チャック装置61から遠ざける。そして、可動チャック装置63が固定チャック装置61から離間した状態で、可動チャック装置63では、エアシリンダ67のロッド67aを凹部66aに進入させ、平角線11を挟持して平角線11の移動を禁止し、次の平角線11の繰出しに備える。
After the flat wire 11 is clamped by the fixed chuck device 61, the actuator 62 of the wire feeding device 60 moves the movable chuck device 63 away from the fixed chuck device 61. Then, in the state where the movable chuck device 63 is separated from the fixed chuck device 61, the rod 67a of the air cylinder 67 enters the recess 66a in the movable chuck device 63 to clamp the rectangular wire 11 and prohibit the movement of the rectangular wire 11. Then, preparations are made for the next feeding of the flat wire 11.
<最初の線材折り曲げ工程>
この状態から平角線11の折り曲げが開始される。まず、巻回機構30の旋回駆動機構33により、旋回ギヤ33cとともにベンダ32を180度に回動させ、図9Aに示すように、平角線11をシャフト31に掛け回すようにして折り曲げる。このとき、プレス機構40(図2)は、フランジ41を用いてシャフト31に沿って折り曲げられる平角線11を厚さ方向から押さえる。 <First wire bending process>
From this state, bending of theflat wire 11 is started. First, the bender 32 is rotated 180 degrees together with the rotation gear 33c by the rotation drive mechanism 33 of the winding mechanism 30, and the rectangular wire 11 is bent so as to be wrapped around the shaft 31, as shown in FIG. 9A. At this time, the press mechanism 40 (FIG. 2) uses the flange 41 to press the rectangular wire 11 that is bent along the shaft 31 from the thickness direction.
この状態から平角線11の折り曲げが開始される。まず、巻回機構30の旋回駆動機構33により、旋回ギヤ33cとともにベンダ32を180度に回動させ、図9Aに示すように、平角線11をシャフト31に掛け回すようにして折り曲げる。このとき、プレス機構40(図2)は、フランジ41を用いてシャフト31に沿って折り曲げられる平角線11を厚さ方向から押さえる。 <First wire bending process>
From this state, bending of the
このとき、フランジ41は、切り欠き部41aが線材繰出し装置60側に位置する向きに配置される。つまり、切り欠き部41aは、U字状に折り曲げられる平角線11の開口部に位置する。これにより、U字状に折り曲げられる平角線11の全ての部分がフランジ41により押さえられるため、平角線11において、シャフト31に掛け回される部位の折り曲げによる膨らみや、折り曲げに起因する曲げしわが防止される。
At this time, the flange 41 is arranged in such a direction that the notch portion 41a is located on the wire rod feeding device 60 side. That is, the cutout portion 41a is located at the opening of the flat wire 11 that is bent into a U-shape. As a result, all portions of the flat wire 11 that are bent into a U-shape are held down by the flange 41, so that the portion of the flat wire 11 that is routed around the shaft 31 does not bulge due to bending or wrinkles due to bending. Prevented.
折り曲げが完了した後は、旋回駆動機構33によりベンダ32を逆方向に180度回動させて最初の位置に戻す。このベンダ32を戻す動作と同時又はその前後に、プレス機構40により、フランジ41による平角線11の押さえを解除する。
After the bending is completed, the bender 32 is rotated 180 degrees in the opposite direction by the rotation drive mechanism 33 and returned to the initial position. Simultaneously with or before or after returning the bender 32, the pressing mechanism 40 releases the flat wire 11 from being held down by the flange 41.
<線材繰出し工程>
次に、図9Bに示すように、線材繰出し装置60により平角線11を長手方向に繰出し、新たに繰出された平角線11をシャフト31とベンダ32の間に挿通させ、最初に折り曲げられた部分11aをY軸方向に移動させてシャフト31から遠ざける。このとき繰出される平角線11の量は、得ようとするエッジワイズコイルの一回巻きに必要な量の半分である。 <Wire rod feeding process>
Next, as shown in FIG. 9B, theflat wire 11 is fed out in the longitudinal direction by the wire feeding device 60, and the newly fed out flat wire 11 is inserted between the shaft 31 and the bender 32, and the first bent portion is 11a is moved in the Y-axis direction away from the shaft 31. The amount of rectangular wire 11 fed out at this time is half the amount required for one winding of the desired edgewise coil.
次に、図9Bに示すように、線材繰出し装置60により平角線11を長手方向に繰出し、新たに繰出された平角線11をシャフト31とベンダ32の間に挿通させ、最初に折り曲げられた部分11aをY軸方向に移動させてシャフト31から遠ざける。このとき繰出される平角線11の量は、得ようとするエッジワイズコイルの一回巻きに必要な量の半分である。 <Wire rod feeding process>
Next, as shown in FIG. 9B, the
この線材繰出し装置60による平角線11の繰出しは、図1及び図2に示すように、固定チャック装置61を開放して平角線11の挟持を解除し、アクチュエータ62により、平角線11を挟持する可動チャック装置63を、図3及び図4に示すように、固定チャック装置61に向けて移動させることにより行われる。可動チャック装置63の移動量に等しい量の平角線11が固定チャック装置61から巻回機構30に向かって繰出される。
To feed out the flat wire 11 by the wire rod feeding device 60, as shown in FIGS. 1 and 2, the fixed chuck device 61 is opened to release the clamping of the flat wire 11, and the actuator 62 grips the flat wire 11. This is done by moving the movable chuck device 63 toward the fixed chuck device 61, as shown in FIGS. 3 and 4. An amount of flat wire 11 equal to the amount of movement of movable chuck device 63 is paid out from fixed chuck device 61 toward winding mechanism 30 .
ここで、平角線11の一回の繰出し量は、可動チャック装置63が固定チャック装置61に接近する量となる。その一回の繰出し量が多くなると、可動チャック装置63と固定チャック装置61の間隔が広がるため、繰出しの際に平角線11が座屈する可能性が高まる。
Here, the amount by which the flat wire 11 is fed out at one time is the amount by which the movable chuck device 63 approaches the fixed chuck device 61. When the amount of one feeding increases, the distance between the movable chuck device 63 and the fixed chuck device 61 increases, and the possibility that the rectangular wire 11 buckles during feeding increases.
しかし、本実施形態の線材繰出し装置60は、可動チャック装置63と固定チャック装置61の間の平角線11を支持する複数の支持片71が等間隔で設けられている。そのため、可動チャック装置63と固定チャック装置61の間の平角線11は複数の支持片71により支持されるので、平角線11の繰出し量を多くしても座屈することはない。
However, in the wire rod feeding device 60 of this embodiment, a plurality of support pieces 71 that support the rectangular wire 11 between the movable chuck device 63 and the fixed chuck device 61 are provided at equal intervals. Therefore, since the flat wire 11 between the movable chuck device 63 and the fixed chuck device 61 is supported by the plurality of support pieces 71, the flat wire 11 will not buckle even if the amount of payout of the flat wire 11 is increased.
必要な量の平角線11が繰出された後は、固定チャック装置61の一対の挟持片61bを互いに接近させて、その間を通過する平角線11を挟んで平角線11の移動を禁止する。
After the required amount of flat wire 11 has been paid out, the pair of clamping pieces 61b of the fixed chuck device 61 are brought close to each other, and movement of the flat wire 11 is prohibited by sandwiching the flat wire 11 passing between them.
それと同時に、可動チャック装置63では、平角線11の挟持を解除し、アクチュエータ62により、可動チャック装置63を固定チャック装置61から遠ざける。そして、可動チャック装置63が固定チャック装置61から離間した状態で、可動チャック装置63は、平角線11を挟持してその移動を禁止し、次の平角線11の繰出しに備える。
At the same time, the movable chuck device 63 releases the clamping of the rectangular wire 11, and the actuator 62 moves the movable chuck device 63 away from the fixed chuck device 61. Then, in a state where the movable chuck device 63 is separated from the fixed chuck device 61, the movable chuck device 63 clamps the flat wire 11 and prohibits its movement, and prepares for feeding out the next flat wire 11.
<線材折り曲げ工程>
新たに平角線11が繰出された後は、図9Cに示すように、旋回駆動機構33によりベンダ32を再び回動させ、平角線11をシャフト31に掛け回すようにして折り曲げる。このとき、プレス機構40により、フランジ41を用いてシャフト31に沿って折り曲げられる平角線11を厚さ方向から押さえる。 <Wire bending process>
After theflat wire 11 is newly paid out, as shown in FIG. 9C, the bender 32 is rotated again by the turning drive mechanism 33, and the flat wire 11 is bent so as to be wrapped around the shaft 31. At this time, the press mechanism 40 presses the rectangular wire 11, which is bent along the shaft 31, from the thickness direction using the flange 41.
新たに平角線11が繰出された後は、図9Cに示すように、旋回駆動機構33によりベンダ32を再び回動させ、平角線11をシャフト31に掛け回すようにして折り曲げる。このとき、プレス機構40により、フランジ41を用いてシャフト31に沿って折り曲げられる平角線11を厚さ方向から押さえる。 <Wire bending process>
After the
このベンダ32を再び回動させる際に、U字状に折り曲げられた部分11aより先の部分11bを、ガイド部材55により持ち上げて切り欠き部41aに通過させる。これにより、部分11bは、シャフト31から外れるため、新たに繰出された平角線11と干渉することなく交差する。
When rotating the bender 32 again, the portion 11b beyond the U-shaped bent portion 11a is lifted by the guide member 55 and passed through the notch 41a. As a result, the portion 11b is detached from the shaft 31, so that it intersects with the newly drawn out rectangular wire 11 without interfering with it.
折り曲げが完了した後は、旋回駆動機構33によりベンダ32を逆方向に180度回動させて最初の位置に戻す。このベンダ32を戻す作業と同時又はその前後に、プレス機構40により、フランジ41による平角線11の押さえを解除する。
After the bending is completed, the bender 32 is rotated 180 degrees in the opposite direction by the rotation drive mechanism 33 and returned to the initial position. Simultaneously with or before or after returning the bender 32, the pressing mechanism 40 releases the flat wire 11 from being held down by the flange 41.
<フランジ移動工程>
次に、図10Aに示すように、フランジ41を移動させ、フランジ41に形成された切り欠き部41aを、平角線11の新たに折り曲げられた部分11dより先の直線部分11eに対応する位置、つまり平角線11の繰出し方向に直交する位置に移動させる。 <Flange movement process>
Next, as shown in FIG. 10A, theflange 41 is moved and the notch 41a formed in the flange 41 is placed at a position corresponding to the straight portion 11e of the rectangular wire 11 beyond the newly bent portion 11d. In other words, it is moved to a position perpendicular to the feeding direction of the flat wire 11.
次に、図10Aに示すように、フランジ41を移動させ、フランジ41に形成された切り欠き部41aを、平角線11の新たに折り曲げられた部分11dより先の直線部分11eに対応する位置、つまり平角線11の繰出し方向に直交する位置に移動させる。 <Flange movement process>
Next, as shown in FIG. 10A, the
フランジ41の移動はフランジ移動機構46(図2)により行われる。具体的には、コントローラからの指令によりモータ47を駆動することにより、駆動プーリ48aを回転させてベルト48cを介して従動プーリ48bを回転させ、従動プーリ48bにスプライン結合されたシャフト31をフランジ41とともに一点鎖線矢印で示すように回転させる。
The movement of the flange 41 is performed by a flange movement mechanism 46 (FIG. 2). Specifically, by driving the motor 47 in response to a command from the controller, the drive pulley 48a is rotated to rotate the driven pulley 48b via the belt 48c, and the shaft 31 spline-coupled to the driven pulley 48b is connected to the flange 41. and rotate it as shown by the dashed-dotted line arrow.
これにより、線材折り曲げ工程時には、線材繰出し装置60側に向いていた切り欠き部41aは、略90度回転移動し、平角線11の繰出し方向に直交する位置に配置される。
As a result, during the wire bending process, the notch portion 41a facing the wire rod feeding device 60 side is rotated approximately 90 degrees and placed at a position perpendicular to the feeding direction of the flat wire 11.
<線材繰出し工程>
次に、図10Bに示すように、線材繰出し装置60により平角線11を長手方向に繰出し、新たに繰出された平角線11をシャフト31とベンダ32の間に挿通させる。 <Wire rod feeding process>
Next, as shown in FIG. 10B, theflat wire 11 is fed out in the longitudinal direction by the wire feeding device 60, and the newly fed out flat wire 11 is inserted between the shaft 31 and the bender 32.
次に、図10Bに示すように、線材繰出し装置60により平角線11を長手方向に繰出し、新たに繰出された平角線11をシャフト31とベンダ32の間に挿通させる。 <Wire rod feeding process>
Next, as shown in FIG. 10B, the
平角線11の繰出しに際し、平角線11の直線部分11eを、切り欠き部41aに通過させてシャフト31の周囲から外す。
When feeding out the flat wire 11, the straight portion 11e of the flat wire 11 is passed through the notch 41a and removed from around the shaft 31.
これにより、一回巻きされたトラック形エッジワイズコイル16がシャフト31から遠ざかるようにY軸方向に移動する。このとき繰出される平角線11の量は、得ようとするエッジワイズコイルの一回巻きに必要な量の半分である。
As a result, the track-shaped edgewise coil 16 wound once moves in the Y-axis direction away from the shaft 31. The amount of rectangular wire 11 fed out at this time is half the amount required for one winding of the desired edgewise coil.
平角線11の繰出しは、上述したように、固定チャック装置61による平角線11の挟持を解除し、アクチュエータ62により、平角線11を挟持する可動チャック装置63を固定チャック装置61に向けて移動させることにより行われる。この際、可動チャック装置63と固定チャック装置61の間に等間隔で設けられた複数の支持片71は、可動チャック装置63と固定チャック装置61の間の平角線11を支持して、平角線11が座屈することを防止する。
To feed out the flat wire 11, as described above, the clamping of the flat wire 11 by the fixed chuck device 61 is released, and the movable chuck device 63 that clamps the flat wire 11 is moved toward the fixed chuck device 61 by the actuator 62. This is done by At this time, the plurality of support pieces 71 provided at equal intervals between the movable chuck device 63 and the fixed chuck device 61 support the rectangular wire 11 between the movable chuck device 63 and the fixed chuck device 61, and 11 from buckling.
必要な量の平角線11が繰出された後は、固定チャック装置61が平角線11を再び挟持して、平角線11の移動を禁止する。それと共に、アクチュエータ62により、平角線11の挟持を解除した可動チャック装置63を、固定チャック装置61から遠ざける。そして、可動チャック装置63は、固定チャック装置61から離間した状態で、平角線11を挟持してその移動を禁止し、次の平角線11の繰出しに備える。
After the required amount of flat wire 11 has been paid out, the fixed chuck device 61 clamps the flat wire 11 again and prohibits movement of the flat wire 11. At the same time, the actuator 62 moves the movable chuck device 63, which has released the clamping of the rectangular wire 11, away from the fixed chuck device 61. Then, the movable chuck device 63 is separated from the fixed chuck device 61, clamps the flat wire 11, prohibits its movement, and prepares for the next feeding of the flat wire 11.
<更なる線材の折り曲げ工程>
新たに平角線11が繰出された後は、図10Cの一点鎖線矢印で示すように、旋回駆動機構33によりベンダ32を再び回動させ、平角線11をシャフト31に掛け回すようにして折り曲げる。このとき、プレス機構40により、フランジ41を用いてシャフト31に沿って折り曲げられる平角線11を厚さ方向から再び押さえる。 <Further wire bending process>
After theflat wire 11 is newly fed out, the bender 32 is rotated again by the turning drive mechanism 33 as shown by the dashed-dotted line arrow in FIG. 10C, and the flat wire 11 is bent so as to be wrapped around the shaft 31. At this time, the press mechanism 40 again presses the rectangular wire 11, which is bent along the shaft 31, from the thickness direction using the flange 41.
新たに平角線11が繰出された後は、図10Cの一点鎖線矢印で示すように、旋回駆動機構33によりベンダ32を再び回動させ、平角線11をシャフト31に掛け回すようにして折り曲げる。このとき、プレス機構40により、フランジ41を用いてシャフト31に沿って折り曲げられる平角線11を厚さ方向から再び押さえる。 <Further wire bending process>
After the
これにより、新たに繰出された平角線11をU字状に折り曲げることができる。この際、フランジ41はU字状に折り曲げられる平角線11の全ての部分を押さえるため、平角線11において、シャフト31に掛け回される部位の折り曲げによる膨らみや、折り曲げに起因する曲げしわが防止される。
Thereby, the newly drawn out rectangular wire 11 can be bent into a U-shape. At this time, the flange 41 holds down all parts of the flat wire 11 that is bent into a U-shape, so that the portion of the flat wire 11 that is routed around the shaft 31 is prevented from bulging due to bending and from bending wrinkles due to bending. be done.
この折り曲げが完了した後は、旋回駆動機構33によりベンダ32を逆方向に180度回動させて最初の位置に戻す。これと同時又はその前後に、プレス機構40により、フランジ41による平角線11の押さえを解除する。
After this bending is completed, the bender 32 is rotated 180 degrees in the opposite direction by the rotation drive mechanism 33 and returned to the initial position. At the same time or before or after this, the press mechanism 40 releases the pressing of the flat wire 11 by the flange 41.
以後、上記した<フランジ移動工程>から<更なる線材の折り曲げ工程>を順次繰り返すことにより、平角線11を整列して巻回し、所定幅、所定層の巻線を行う。これにより、フランジ41の上面に、Z軸方向に延びるエッジワイズコイル16が形成される。
Thereafter, by sequentially repeating the above-described <flange moving process> to <further wire bending process>, the rectangular wires 11 are aligned and wound to form a wire of a predetermined width and a predetermined layer. As a result, the edgewise coil 16 extending in the Z-axis direction is formed on the upper surface of the flange 41.
こうして所望のエッジワイズコイル16を形成した後は、カッタ装置(図示せず)により平角線11を切断してエッジワイズコイル16を取り外す。これにより一連の巻線作業が終了する。
After forming the desired edgewise coil 16 in this way, the rectangular wire 11 is cut using a cutter device (not shown) and the edgewise coil 16 is removed. This completes a series of winding operations.
巻線装置10では、線材繰出し装置60が繰出す平角線11の量や、シャフト31の曲率半径等を変えることにより、エッジワイズコイル16の大きさや形状を容易に変更することができる。
In the winding device 10, the size and shape of the edgewise coil 16 can be easily changed by changing the amount of flat wire 11 fed out by the wire feeding device 60, the radius of curvature of the shaft 31, etc.
特に、線材繰出し装置60による平角線11の繰出し量の変更は、アクチュエータ62による可動チャック装置63の移動量を変更するだけなので容易である。平角線11の繰出し量が大きい場合であっても、繰出される平角線11は複数の支持片71により支持されるので、平角線11の座屈を防止しつつ繰出すことができる。
In particular, changing the amount of feeding out of the rectangular wire 11 by the wire feeding device 60 is easy because only the amount of movement of the movable chuck device 63 by the actuator 62 is changed. Even when the flat wire 11 is fed out by a large amount, the flat wire 11 is supported by the plurality of support pieces 71, so that the flat wire 11 can be fed out while preventing buckling.
また、所定間隔を空けて複数の支持片71が配置され隣り合う支持片71の離接が可能であるため、線材繰出し装置60の大型化が防止される。また、平角線11の繰出し量を増減する際には、支持片71の数を増減させることにより対応できるため、効果的に平角線11の座屈を防止できる。
Furthermore, since the plurality of support pieces 71 are arranged at predetermined intervals and adjacent support pieces 71 can be moved toward and away from each other, the wire rod feeding device 60 is prevented from increasing in size. Further, when increasing or decreasing the amount of feed of the flat wire 11, this can be done by increasing or decreasing the number of support pieces 71, so buckling of the flat wire 11 can be effectively prevented.
支持ロッド68に複数の支持片71が移動可能に設けられるため、複数の支持片71を容易に直線状に配置することができ、かつ支持片71の数を容易に増減させることができる。一方、支持片71の数が増えると、支持ロッド68が湾曲するような事態も考えられるが、固定チャック装置61と可動チャック装置63に亘ってかつ可動チャック装置63を貫通する補強ロッド77が設けられているため、複数の支持片71が湾曲して設けられることが防止される。支持ロッド68が湾曲するおそれがない場合には、補強ロッド77は不要である。
Since the plurality of support pieces 71 are movably provided on the support rod 68, the plurality of support pieces 71 can be easily arranged in a straight line, and the number of support pieces 71 can be easily increased or decreased. On the other hand, if the number of support pieces 71 increases, the support rod 68 may become curved. Therefore, the plurality of support pieces 71 are prevented from being provided in a curved manner. If there is no possibility that the support rod 68 will bend, the reinforcing rod 77 is not necessary.
線材繰出し装置60と巻回機構30を備える巻線装置10では、線材繰出し装置60により平角線11が座屈することなく正確に繰出されるので、所望な大きさのコイル、例えばエッジワイズコイルを得ることができる。
In the winding device 10 including the wire rod feeding device 60 and the winding mechanism 30, the flat wire 11 is accurately fed out without buckling by the wire feeding device 60, so that a coil of a desired size, for example, an edgewise coil can be obtained. be able to.
上記実施形態では、線材が厚さに対して幅が広い平角線11である形態について説明した。しかし、これは一例であって、線材は平角線でなくても良い。例えば、断面が方形の角線であってもよく、断面が円形の丸線であってもよい。
In the above embodiment, the wire rod is a rectangular wire 11 whose width is wider than its thickness. However, this is just an example, and the wire does not have to be a rectangular wire. For example, it may be a square wire with a rectangular cross section, or a round wire with a circular cross section.
この場合、必要に応じて線材を支持する支持片71を、その線材の断面形状に応じて変更する必要があるが、支持ロッド68に複数の支持片71を移動可能に設けているため、支持片71の変更も容易である。
In this case, it is necessary to change the support piece 71 that supports the wire according to the cross-sectional shape of the wire, but since the support rod 68 is movably provided with a plurality of support pieces 71, the support Changing the piece 71 is also easy.
また、上記実施形態では、平角線11を幅方向に巻回してエッジワイズコイルを得る形態について説明した。しかし、これは一例であって、方形のコイルや、円形のコイルを得る形態でもよい。
Furthermore, in the embodiment described above, the flat wire 11 is wound in the width direction to obtain an edgewise coil. However, this is just an example, and a rectangular coil or a circular coil may also be obtained.
更に、上記実施形態では、配置手段が、複数の支持片71の間に介在されたコイルスプリング76である形態について説明した。しかし、これは一例であって、配置手段は、コイルスプリング76以外の弾性部材であってもよい。
Further, in the above embodiment, the configuration in which the arrangement means is a coil spring 76 interposed between a plurality of support pieces 71 has been described. However, this is just an example, and the arrangement means may be an elastic member other than the coil spring 76.
以上、本発明の実施形態について説明したが、上記実施形態は本発明の適用例の一部を示したに過ぎず、本発明の技術的範囲を上記実施形態の具体的構成に限定する趣旨ではない。
Although the embodiments of the present invention have been described above, the above embodiments merely show a part of the application examples of the present invention, and are not intended to limit the technical scope of the present invention to the specific configurations of the above embodiments. do not have.
