Description

【0001】
【発明の属する技術分野】
本発明は、巻線装置などに使用する線材の把持装置に関するものである。
【0002】
【従来の技術】
従来の太線および細線用の線材の把持装置の要部構成を図3、図4に示す。従来における太線用の線材の把持装置は、図3に示すように片面に線材9の先端などの把持部分を設けたアングル状の固定爪1と、片面が前記の片面と通常時には当接し押圧するように、ねじりコイル状のバネ5とその中を挿通する支点ピン4で固定爪1に回動自在に組合わされたアングル状の可動爪2で構成されている。
【0003】
ノズル8を挿通し導出された線材9の先端を把持する場合、エアシリンダ6の駆動により、可動爪2を回動して固定爪1と可動爪2との当接面に隙間を設ける。そして、その隙間に線材9の先端を挿通し配設した後、エアシリンダ6を駆動して元の位置とし、バネ5の張力により付勢して可動爪2を元の状態にして固定爪1との間で線材9を把持する。
【0004】
そして、各種動作終了後などで線材9を開放する場合には、前記と同じ動作で固定爪1と可動爪2との当接面に隙間を設けた後、線材9を開放する。
【0005】
また、細線用の線材の把持装置は、図4に示すように、スリット10aを中心部の長手方向に設けた円筒状の線把持ピン10の外周に細線の線材9を巻回し、線材9と線把持ピン10、あるいは線材9同士の摩擦力により線材9を保持していた。
【0006】
線材9を開放する場合は、線把持ピン10のスリット10aに一端を上下方向に摺動自在に嵌め込んだ排出腕3を、エアシリンダ7の駆動により上方向すなわちスリット10aの根元より先端部方向に移動させて、線材9を線把持ピン10の外周より分離し抜取っていた。
【0007】
【発明が解決しようとする課題】
しかしながら前記従来のものでは図3に示す太線用の線材の把持装置、図4に示す細線用の線材の把持装置がそれぞれ必要であった。
【0008】
本発明は、前記従来の課題を解決しようとするものであり、線材の太さに関係なく把持が可能な線材の把持装置を提供しようとするものである。
【0009】
【課題を解決するための手段】
前記課題を解決するために、本発明の線材の把持装置は、片面が段階状でかつ、巻付けられた線材を排出する移動自在な排出腕が移動するスリットを設けた固定爪と、前記段階状の片面と当接する片面を有し、バネにより付勢されかつ回動自在に固定爪に対応して設置された可動爪により線材を把持する構成としたものであり、細線および太線も容易にかつ、確実に把持および排出することが可能となる。
【0010】
【発明の実施の形態】
本発明の請求項1に記載の発明は、片面が段階状でなり、巻付けられた線材を排出する移動自在な排出腕の一辺が移動するスリットを設けた固定爪と、前記段階状の片面と当接する片面を有し、バネにより付勢されかつ回動自在に固定爪に対応して設置された可動爪とにより構成したものであり、線材の太さや形状および方向に関係なく、線材を把持および排出できるという作用を有する。
【0011】
以下、本発明の実施の形態を図面を用いて説明する。図1は本発明の実施の形態における線材の把持装置における要部斜視図である。図1において、11はセラミック材あるいは鋼材などの金属材でなる固定爪であり、アングル形状で上部先端中央部にはスリット11aが上下方向に設けられている。
【0012】
13は同じ材料でなるロ字状の排出腕であり、一辺部がスリット11a中をエアシリンダ17の駆動により上下に摺動、あるいは非接触で移動自在となっている。
【0013】
12は同じ材料でなる固定爪11と対応するアングル状の可動爪であり、上部先端の段階状片面が、対応する固定爪11の先端の段階状片側面に当接し、下部が支点ピン14を介して固定爪11の下部に回動自在に組合されており、支点ピン14を中に挿通させたねじりコイル状のバネ15により、可動爪12を固定爪11に付勢して前記先端の段階状片側面同士を当接し押付けるトルクを与えている。
【0014】
16はエアシリンダであり、その駆動によりバネ15の付勢力に抗して可動爪12を回動させて、固定爪11との上部先端の段階状片側面の当接を開放する。
【0015】
18はノズルであり、絶縁被膜された銅材などでなる巻線用の線材19を導出し、その先端から所定箇所に供給する。
【0016】
なお、固定爪11と可動爪12の上部における先端の段階状片側面により形成される隙間は、各々の段差により可動爪12が固定爪11より解放された状態でも、直線的な上下方向には線材19あるいはノズル18が通り抜けできない構成となっている。
【0017】
次に動作について図1,図2を用いて説明する。まず、線材19を把持するために、エアシリンダ16を図2のごとく駆動させて可動爪12を回動して先端の段階状片側面を固定爪11との当接から解放して、線材19あるいはノズル18の直径より大きい隙間を形成する。
【0018】
そして、この図2に示すようにノズル18を固定爪11の前面を(イ)の矢印線で示すように、右下から左上に移動させ、さらに固定爪11と可動爪12との隙間上部を(ロ)の矢印線で示すように手前から奥、すなわち左下から右上に通過させる。
【0019】
その際、前記の固定爪11と可動爪12の形状とその設定により、初期状態におけるノズル18より先の線材19の形状、およびその方向がいかなる方向であっても、前記動作におけるノズル18の移動軌跡により、固定爪11と可動爪12との間の隙間に線材9を通過および存在させることが出来る。
【0020】
この状態で、エアシリンダ16を駆動して元の状態に復帰させ、バネ15の付勢により可動爪12を閉じて線材19を固定爪11との間で把持する。さらにこの状態で、ノズル18を上面側から見て時計周り方向に、固定爪11と可動爪12の外周を1周させて線材19を巻付ける事により、線材19の把持すなわち保持を確実なものとする。
【0021】
細線の線材19の場合など、固定爪11と可動爪12との挟持による線材19の把持が不十分と思われる場合には、さらに巻付け回数を増加させて把持をより十分となるようにしてもよい。
【0022】
所定の工程動作などの終了後、把持した線材19を排出する場合は、エアシリンダ16を駆動させて可動爪12を開放した状態で、さらにエアシリンダ17を駆動させて排出腕13を固定爪11のスリット11aの根元から先端間で移動させる。すると、把持されていた線材19は固定爪11の外周を必ず1周以上させているため、排出腕13の1辺により固定爪11および可動爪12から解放され分離して排出する事ができる。
【0023】
なお、使用する線材19、ノズル18の太さやサイズによりエアシリンダ16の駆動距離などを制御して可動爪12と固定爪11との隙間を最適に設定すればよく、さらにまたノズル18の駆動による線材19の巻回は、線材19の種類により固定爪11のみの巻回としてもよい。
【0024】
【発明の効果】
以上、本発明の線材の把持装置によれば、細線や太線など線材の太さによる影響がなく、線材を把持あるいは排出することができ、初期状態の線材の形状やその方向に関係なく把持および排出が確実に出来るという効果を有する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wire gripping device used for a winding device or the like.
[0002]
[Prior art]
FIGS. 3 and 4 show the configuration of a main part of a conventional wire gripping device for thick and thin wires. A conventional wire gripping device for a thick wire has an angle-shaped fixed claw 1 provided with a gripping portion such as the tip of a wire 9 on one side as shown in FIG. 3, and one side abuts and presses the above one side at normal times. As described above, it is constituted by the angle-shaped movable claw 2 rotatably combined with the fixed claw 1 by the torsion coil-shaped spring 5 and the fulcrum pin 4 inserted therethrough.
[0003]
When gripping the distal end of the wire 9 drawn out through the nozzle 8, the movable claw 2 is rotated by driving the air cylinder 6 to provide a gap on the contact surface between the fixed claw 1 and the movable claw 2. After the distal end of the wire 9 is inserted through the gap and disposed, the air cylinder 6 is driven to the original position, and the movable claw 2 is urged by the tension of the spring 5 to return the movable claw 2 to its original state. And the wire rod 9 is gripped.
[0004]
When the wire 9 is released after various operations are completed, a gap is provided in the contact surface between the fixed claw 1 and the movable claw 2 by the same operation as described above, and then the wire 9 is released.
[0005]
In addition, as shown in FIG. 4, the wire gripping device for a thin wire winds a thin wire 9 around a cylindrical wire gripping pin 10 having a slit 10 a provided in a longitudinal direction of a central portion thereof. The wire 9 was held by the wire gripping pin 10 or the frictional force between the wires 9.
[0006]
To release the wire 9, the discharge arm 3, one end of which is slidably fitted in the slit 10 a of the wire gripping pin 10 slidably in the up-down direction, is driven upward by the air cylinder 7, that is, from the root of the slit 10 a toward the tip. To separate the wire 9 from the outer periphery of the wire gripping pin 10 and extract it.
[0007]

However, in the above-described conventional apparatus, a gripping device for a thick wire shown in FIG. 3 and a gripping device for a thin wire shown in FIG. 4 are required.
[0008]
SUMMARY OF THE INVENTION The present invention is to solve the above-mentioned conventional problems, and an object of the present invention is to provide a wire rod gripping device capable of gripping regardless of the thickness of the wire rod.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a wire gripping device of the present invention has a fixed claw provided with a slit having a stepped shape on one side and a movable discharge arm for discharging a wound wire rod. It has a single side that comes in contact with one side of the shape, and is configured to be gripped by a movable claw that is urged by a spring and is rotatably installed corresponding to a fixed claw. In addition, it is possible to reliably hold and discharge.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
The invention according to claim 1 of the present invention is characterized in that a fixed claw having a stepped surface on one side and a slit provided on one side of a movable discharge arm for discharging a wound wire rod is provided, and the stepped single surface. And a movable claw that is biased by a spring and is rotatably installed in correspondence with the fixed claw, regardless of the thickness, shape, and direction of the wire. It has the effect of being able to grasp and discharge.
[0011]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a main part of a wire gripping device according to an embodiment of the present invention. In FIG. 1, reference numeral 11 denotes a fixed claw made of a metal material such as a ceramic material or a steel material. The fixed claw 11 has an angle shape and a slit 11a is provided in the center of an upper end in a vertical direction.
[0012]
Numeral 13 denotes a square-shaped discharge arm made of the same material, one side of which can be slid up and down or driven in a non-contact manner by driving an air cylinder 17 in the slit 11a.
[0013]
Reference numeral 12 denotes an angle-shaped movable claw corresponding to the fixed claw 11 made of the same material. The stepped one surface of the upper end contacts the corresponding stepped one side surface of the corresponding fixed claw 11, and the lower portion supports the fulcrum pin 14. The movable claw 12 is urged to the fixed claw 11 by a torsion coil-shaped spring 15 having a fulcrum pin 14 inserted through the lower end of the fixed claw 11 so as to be freely rotatable. A torque is applied to press the side surfaces of the pieces in contact with each other.
[0014]
Reference numeral 16 denotes an air cylinder, which rotates the movable claw 12 against the urging force of the spring 15 by driving thereof to release the contact of the stepped one side surface of the upper end with the fixed claw 11.
[0015]
Reference numeral 18 denotes a nozzle, which derives a wire 19 for winding made of an insulating-coated copper material or the like, and supplies the wire 19 to a predetermined location from the tip.
[0016]
In addition, the gap formed by the stepped one side surface at the top of the fixed claw 11 and the movable claw 12 is linear in the vertical direction even when the movable claw 12 is released from the fixed claw 11 due to each step. The wire 19 or the nozzle 18 cannot pass through.
[0017]
Next, the operation will be described with reference to FIGS. First, in order to grip the wire 19, the air cylinder 16 is driven as shown in FIG. 2 to rotate the movable claw 12 to release the stepped one side surface of the tip from contact with the fixed claw 11. Alternatively, a gap larger than the diameter of the nozzle 18 is formed.
[0018]
Then, as shown in FIG. 2, the nozzle 18 is moved from the lower right to the upper left from the lower right to the front of the fixed claw 11 as indicated by the arrow line (a), and the upper part of the gap between the fixed claw 11 and the movable claw 12 is moved. As shown by the arrow line in (b), the light is passed from the front to the back, that is, from the lower left to the upper right.
[0019]
At this time, due to the shapes and settings of the fixed claws 11 and the movable claws 12, the movement of the nozzles 18 in the above-mentioned operation is performed regardless of the shape and the direction of the wire 19 before the nozzles 18 in the initial state. The wire 9 can pass through and exist in the gap between the fixed claw 11 and the movable claw 12 by the trajectory.
[0020]
In this state, the air cylinder 16 is driven to return to the original state, the movable claw 12 is closed by the bias of the spring 15, and the wire 19 is gripped with the fixed claw 11. Further, in this state, the wire 19 is wound around the nozzle 18 around the outer circumference of the fixed claw 11 and the movable claw 12 in a clockwise direction when viewed from the upper surface side, so that the wire 19 is securely held or held. And
[0021]
When it is considered that the gripping of the wire 19 between the fixed claw 11 and the movable claw 12 is insufficient, such as in the case of a thin wire 19, the number of windings is further increased so that the grip is more sufficient. Is also good.
[0022]
When the gripped wire 19 is discharged after the end of a predetermined process operation, the air cylinder 16 is driven to open the movable claw 12, and the air cylinder 17 is further driven to fix the discharge arm 13 to the fixed claw 11. Is moved from the root to the tip of the slit 11a. Then, since the gripped wire 19 always makes the outer periphery of the fixed claw 11 at least one round, the wire 19 is released from the fixed claw 11 and the movable claw 12 by one side of the discharge arm 13 and can be separated and discharged.
[0023]
The gap between the movable claw 12 and the fixed claw 11 may be set optimally by controlling the driving distance of the air cylinder 16 according to the thickness and size of the wire rod 19 and the nozzle 18 to be used. The winding of the wire 19 may be a winding of only the fixing claw 11 depending on the type of the wire 19.
[0024]
【The invention's effect】
As described above, according to the wire gripping device of the present invention, the wire can be gripped or discharged without being affected by the thickness of the wire, such as a thin wire or a thick wire, and can be gripped and discharged regardless of the shape and direction of the wire in the initial state. This has the effect that discharge can be reliably performed.
