Description

本発明は、電子機器に使用される電子部品であるアルミ電解コンデンサ、電池等の製造に使用される巻取装置およびその方法に関するものである。   The present invention relates to a winding device used for manufacturing an aluminum electrolytic capacitor, a battery or the like, which is an electronic component used in an electronic device, and a method thereof.

従来の電子部品の巻取装置について図面を用いて説明する。   A conventional electronic component winding device will be described with reference to the drawings.

図７、及び図８は、従来の帯状材料を巻回する巻取装置の構成概念図である。   7 and 8 are conceptual diagrams of the configuration of a winding device for winding a conventional belt-shaped material.

図７の巻取装置においては、リール等で供給される帯状材料１を巻出機構２にて巻き出し、ダンサーローラ３にて張力を付加しながら、回転動力（図示せず）で駆動される巻軸４により巻取り素子を形成する。   In the winding device of FIG. 7, the belt-shaped material 1 supplied by a reel or the like is unwound by the unwinding mechanism 2 and is driven by rotational power (not shown) while applying tension by the dancer roller 3. A winding element is formed by the winding shaft 4.

さらに、この巻取装置は、部材を所定長さに切断する切断機構５と、切断後の帯状材料先端部を挟んで保持し、巻軸４に送出する先端送出機構６を備える。   Further, the winding device includes a cutting mechanism 5 that cuts the member into a predetermined length, and a tip feeding mechanism 6 that holds the tip of the strip-shaped material after cutting and feeds it to the winding shaft 4.

また、図８の巻取装置においては、図７の巻取装置に加えて、帯状材料を幅方向の規定された位置に位置決めする固定ガイド７を備える。   In addition to the winding device of FIG. 7, the winding device of FIG. 8 includes a fixed guide 7 that positions the band-shaped material at a specified position in the width direction.

しかしながら、図７に示す巻取装置では、ダンサーローラ３の張力を大きくすれば、図６に示すような巻取り素子９の巻きずれ１０は低減できるものの、完全に巻きずれを防止することはできず、張力を大きくすれば帯状材料を破壊してしまうという可能性がある。   However, in the winding device shown in FIG. 7, if the tension of the dancer roller 3 is increased, the winding deviation 10 of the winding element 9 as shown in FIG. 6 can be reduced, but the winding deviation can be completely prevented. However, if the tension is increased, the band-shaped material may be destroyed.

さらに、リール等で供給される帯状材料の巻出位置がずれてしまうと、そのずれがそのまま巻きずれとなってしまうという課題を有していた。   Furthermore, if the unwinding position of the belt-shaped material supplied by a reel or the like is deviated, there is a problem that the deviation is directly unwound.

そして、さらに、多数の巻取り素子を形成する中で、巻きずれが蓄積し、その巻きずれを規正することができないという課題も有していた。   Further, in the formation of a large number of winding elements, there has been a problem that winding deviation accumulates and the winding deviation cannot be regulated.

また、図８に示すもう一つの巻取装置では、固定ガイド７により巻きずれを規正できるが、帯状材料の移送中に固定ガイド７との間の擦れにより粉塵が発生し、その粉塵が巻取り素子内に巻き込まれ、巻取り素子の特性不良（ショート不良等）が発生する可能性がある。   Further, in another winding device shown in FIG. 8, the winding deviation can be regulated by the fixed guide 7, but dust is generated by rubbing with the fixed guide 7 during the transfer of the belt-like material, and the dust is wound up. There is a possibility that the winding element will be caught in the element and the characteristic of the winding element (short circuit defect, etc.) may occur.

さらに、その擦れにより帯状材料に傷が発生し、その傷によって巻取り素子の特性不良（ショート不良等）が発生する可能性がある。   Further, the rubbing may cause scratches in the belt-like material, and the scratches may cause defective characteristics (such as short-circuit defects) of the winding element.

この帯状材料の移送中の擦れによる粉塵や傷の発生は、図９（ａ）に示す固定ガイド７でも、また図９（ｂ）に示すツバ付きローラ８でも発生してしまう。   The generation of dust and scratches due to rubbing during the transfer of the belt-shaped material occurs also in the fixed guide 7 shown in FIG. 9A and also in the roller 8 with the flange shown in FIG. 9B.

これらは、電子部品の内部構造である巻取り素子の品質に大きく影響する課題であり、従来から巻取装置において問題となっていた。   These are problems that greatly affect the quality of the winding element, which is the internal structure of the electronic component, and have conventionally been a problem in winding apparatuses.

本発明は、前記課題を解決しようとするものであり、巻取り素子の巻きずれなく、しかも、帯状材料の移送中に固定ガイドとの間の擦れによる粉塵や傷の発生をなくす巻取装置およびその方法を提供することを目的とするものである。   The present invention is intended to solve the above-described problem, and a winding device that eliminates the occurrence of dust and scratches due to rubbing with a fixed guide during the transfer of the belt-shaped material without causing winding of the winding element, and The object is to provide such a method.

前記目的を達成するために、本発明の請求項１に記載の発明は、リール等で供給される帯状材料の巻出機構と、帯状材料の移送経路上にある単数あるいは複数の位置決め機構と、帯状材料の移送経路に沿って移動可能な把持機構と、帯状材料を所定長さに切断する切断機構と、回転動力で駆動される巻軸と、帯状材料の先端部を保持し巻軸へ送出する先端送出機構とを備えた巻取装置であり、連続的に巻取り素子の形成が可能となる作用効果を有する。   In order to achieve the above object, the invention according to claim 1 of the present invention includes an unwinding mechanism for a belt-shaped material supplied by a reel or the like, and one or a plurality of positioning mechanisms on a transport path for the belt-shaped material, A gripping mechanism that can move along the transport path of the belt-shaped material, a cutting mechanism that cuts the belt-shaped material into a predetermined length, a winding shaft that is driven by rotational power, and a tip portion of the belt-shaped material that is held and sent to the winding shaft The winding device includes a leading-end delivery mechanism that has a function and an effect of continuously forming a winding element.

本発明の請求項２に記載の発明は、特に上記に述べた構成に加えて把持機構に一定方向への張力を付加する張力発生機構を有しており、これにより、より安定して連続的に巻取り素子の形成が可能であるという作用効果を有する。   The invention according to claim 2 of the present invention has a tension generating mechanism for applying a tension in a certain direction to the gripping mechanism in addition to the above-described configuration, and thereby more stable and continuous. In addition, the winding element can be formed.

本発明の請求項３に記載の発明は、特に位置決め機構を、ある一定の範囲で回転可能であり、さらに帯状材料の幅方向にもある一定の範囲で可動でありながら、その各々の中心位置に復帰しようとする弾性力を備えた帯状材料の吸着プレートと、その吸着プレート上の帯状材料を幅方向の規定された位置に位置決めする開閉式ガイドで構成しており、これによって、薄い帯状材料であっても平面で安定して吸着保持することができる。   The invention according to claim 3 of the present invention is particularly capable of rotating the positioning mechanism within a certain range and further movable within a certain range in the width direction of the belt-like material, while each center position thereof is It is composed of a belt-shaped material suction plate that has an elastic force to return to the position, and an openable guide for positioning the belt-shaped material on the suction plate at a specified position in the width direction. Even so, it can be stably adsorbed and held on a flat surface.

さらに、この位置決め機構においては、吸着プレートは回転および幅方向に可動であるので、帯状材料を吸着プレートで吸着保持した状態で開閉式ガイドによって位置決めし、その後把持機構で帯状材料を把持しなおすことで、帯状材料が吸着プレート上で擦れないので、粉塵や傷の発生なく帯状材料の位置決めができるという作用効果を有する。   Further, in this positioning mechanism, the suction plate is movable in the rotation and width directions, so that the belt-shaped material is positioned by the openable guide while being sucked and held by the suction plate, and then the belt-shaped material is gripped again by the gripping mechanism. Thus, since the band-shaped material is not rubbed on the suction plate, the band-shaped material can be positioned without generating dust or scratches.

本発明の請求項４に記載の発明は、特に張力発生機構を、サーボモータで駆動されるプーリと、一端をプーリで巻き取られ他端を把持機構に接続される線状部材で構成しており、これによって、弾性係数が一定であるバネ等とは異なり、サーボモータのトルク制御を用いて、帯状材料の違いに合せて張力を可変にでき、かつ、巻取り中の張力も可変にできるという作用効果を有する。   In the invention according to claim 4 of the present invention, in particular, the tension generating mechanism includes a pulley driven by a servo motor and a linear member having one end wound up by the pulley and the other end connected to the gripping mechanism. Thus, unlike a spring or the like having a constant elastic coefficient, the tension can be made variable according to the difference in the belt-like material using the torque control of the servo motor, and the tension during winding can be made variable. It has the effect of.

本発明の請求項５に記載の発明は、帯状材料の移送経路上にある単数あるいは複数の位置決め機構で、帯状材料を移送停止中に位置決めした後、帯状材料の移送経路に沿って移動可能な把持機構で帯状材料を把持し、その後、位置決め機構を開放し、把持機構で帯状材料を把持しながら、同時に把持機構を介して帯状材料に張力を付加しながら、帯状材料を巻回して巻取り素子を形成するものであって、巻きずれなく、しかも、帯状材料の移送中に固定ガイドとの間の擦れによる粉塵や傷の発生をなくすことができるという作用効果を有する。   According to the fifth aspect of the present invention, the single or plural positioning mechanisms on the belt material transfer path can be moved along the belt material transfer path after positioning the belt material while the transfer is stopped. Gripping the belt-shaped material with the gripping mechanism, then opening the positioning mechanism, gripping the belt-shaped material with the gripping mechanism, and simultaneously applying tension to the belt-shaped material via the gripping mechanism An element is formed, and has an effect that there is no winding deviation and generation of dust and scratches due to rubbing with the fixed guide during transfer of the belt-shaped material can be eliminated.

本発明の巻取装置およびその方法は、巻取り素子の巻きずれがなく、しかも、帯状材料の移送中に固定ガイドとの間の擦れによる粉塵や傷の発生をなくすことができ、電子部品の内部構造である巻取り素子の品質レベルを向上できるという効果を有する。   The winding device and the method of the present invention are free from winding displacement of the winding element, and can eliminate generation of dust and scratches due to rubbing between the belt-shaped material and the fixed guide. This has the effect of improving the quality level of the winding element, which is an internal structure.

以下、本発明を実施するための最良の形態について、図面を参照しながら説明する。   The best mode for carrying out the present invention will be described below with reference to the drawings.

（実施の形態１）
実施の形態１を用いて、本発明の特に請求項１〜２，５に記載の発明について説明する。 (Embodiment 1)
The first and second aspects of the present invention will be described with reference to the first embodiment.

なお、背景技術において説明したものと同じ構成については、同じ符号を用い、説明は省略する。   In addition, about the same structure as what was demonstrated in background art, the same code | symbol is used and description is abbreviate | omitted.

図１は、本発明の実施の形態１における巻取装置の構成概念図であり、初めに構成について説明する。   FIG. 1 is a conceptual diagram of the configuration of the winding device according to Embodiment 1 of the present invention. First, the configuration will be described.

図１において、ダンサーローラ３と先端送出機構６の間に、帯状材料１の位置決め機構１１と、帯状材料の搬送経路に沿ってスライダ１３等を用いて移動可能な把持機構１２と、その把持機構１２に一定方向への張力を付加する張力発生機構１４を備える。   In FIG. 1, between the dancer roller 3 and the tip delivery mechanism 6, a positioning mechanism 11 for the belt-shaped material 1, a gripping mechanism 12 that can be moved using a slider 13 or the like along the transport path of the belt-shaped material, and the gripping mechanism. 12 is provided with a tension generating mechanism 14 for applying a tension in a certain direction.

この実施の形態１におけるダンサーローラ３は、帯状材料の位置決めや把持時に、帯状材料をたわまないようにする張力を発生するだけでよく、図７及び、図８に示す従来の実施例の巻取装置におけるダンサーローラ３が発生する張力に比べて小さい。   The dancer roller 3 according to the first embodiment only needs to generate a tension that prevents the band-shaped material from being bent at the time of positioning and gripping the band-shaped material, and the dancer roller 3 of the conventional example shown in FIGS. It is smaller than the tension generated by the dancer roller 3 in the winding device.

図２は、本発明の実施の形態１における巻取装置の位置決め機構１１の断面図であり、帯状材料を受ける下ガイド１５と開閉式ガイド１６から構成される。   FIG. 2 is a cross-sectional view of the positioning mechanism 11 of the winding device according to the first embodiment of the present invention, and includes a lower guide 15 that receives the belt-like material and an openable guide 16.

図３は、本発明の実施の形態１における巻取装置の構成概念を示す斜視図であり、帯状材料には端子１７がついている事例を示している。   FIG. 3 is a perspective view showing the configuration concept of the winding device according to the first embodiment of the present invention, and shows an example in which the terminal 17 is attached to the belt-like material.

次に動作について説明する。   Next, the operation will be described.

まず、リール等で供給される帯状材料１は巻出機構２より巻き出され、その帯状材料１の先端は、先端送出機構６に把持されている。   First, the strip-shaped material 1 supplied by a reel or the like is unwound from the unwinding mechanism 2, and the leading end of the strip-shaped material 1 is held by the leading-end feeding mechanism 6.

そして、帯状材料１の移送経路上にある位置決め機構１１で帯状材料１を位置決めした後、帯状材料１の移送経路に沿って移動可能な把持機構１２で帯状材料１を把持し、その後、位置決め機構１１を開放する。   And after positioning the strip | belt-shaped material 1 with the positioning mechanism 11 on the transfer path | route of the strip | belt-shaped material 1, the strip | belt-shaped material 1 is gripped with the holding | grip mechanism 12 which can move along the transfer path | route of the strip | belt-shaped material 1, and then a positioning mechanism 11 is released.

この段階で帯状材料１は幅方向の規定された位置に位置決めできているので、把持機構１２で帯状材料１を把持しながら、同時に張力発生機構１４によって帯状材料１に張力を付加しながら、帯状材料１の先端を先端送出機構６により巻軸４に固定（巻軸への固定方法は図示せず）した後、巻軸４で巻回して巻取り素子を形成する。   At this stage, since the band-shaped material 1 can be positioned at a predetermined position in the width direction, the band-shaped material 1 is gripped by the gripping mechanism 12 and at the same time tension is applied to the band-shaped material 1 by the tension generating mechanism 14. The tip of the material 1 is fixed to the winding shaft 4 by the tip delivery mechanism 6 (the fixing method to the winding shaft is not shown), and then wound around the winding shaft 4 to form a winding element.

位置決め機構１１の動作について図２を用いて説明すると、図２（ａ）は位置決めが開放した状態であり、位置決め動作をする際には図２（ｂ）のように下ガイド１５で帯状材料１を規正の高さに位置決めした後、図２（ｃ）のように開閉式ガイド１６で帯状材料１を幅方向の規定された位置に位置決めし、そして、位置決めが開放する際には図２（ｂ）の状態を経て、図２（ａ）の状態に戻る。   The operation of the positioning mechanism 11 will be described with reference to FIG. 2. FIG. 2 (a) shows a state in which the positioning is released. When performing the positioning operation, the belt-shaped material 1 is formed by the lower guide 15 as shown in FIG. 2 (b). 2 is positioned at a predetermined height, and the band-shaped material 1 is positioned at a specified position in the width direction by the openable guide 16 as shown in FIG. 2 (c). After the state of b), the state returns to the state of FIG.

そして、巻軸４で所定長さの帯状材料１を巻回した後は、初期位置に戻っている先端送出機構６で帯状材料１を把持し、切断機構５で帯状材料１を切断する。   Then, after winding the belt-shaped material 1 having a predetermined length with the winding shaft 4, the belt-shaped material 1 is gripped by the tip delivery mechanism 6 that has returned to the initial position, and the belt-shaped material 1 is cut by the cutting mechanism 5.

巻取り素子側の帯状材料端は切断後に自由になっている為、テープ貼り付け機構等（図示せず）を用いて帯状材料端を巻取り素子へ固定した後、巻軸４から巻取り素子を取り外すと巻取り素子が完成する。   Since the belt-like material end on the winding element side is free after cutting, after fixing the belt-like material end to the winding element by using a tape attaching mechanism or the like (not shown), the winding element is taken from the winding shaft 4. When the is removed, the winding element is completed.

搬送経路上にある把持機構１２は、巻軸４で帯状材料１を巻回している間は帯状材料１の動きに追従して巻軸４の方へ移動するが、巻軸４が所定長さを巻回して回転停止し、先端送出機構６が帯状材料１を把持した後には、その位置で把持機構１２を開放する。   The gripping mechanism 12 on the transport path moves toward the winding shaft 4 following the movement of the strip-shaped material 1 while the strip-shaped material 1 is being wound around the winding shaft 4, but the winding shaft 4 has a predetermined length. After the tip delivery mechanism 6 grips the strip-shaped material 1, the gripping mechanism 12 is opened at that position.

すると、把持機構１２は張力発生機構１４にて巻出機構２の方向へ引っ張られているのでストッパー等（図示せず）で決められた初期位置まで移動する。   Then, since the gripping mechanism 12 is pulled in the direction of the unwinding mechanism 2 by the tension generating mechanism 14, the gripping mechanism 12 moves to an initial position determined by a stopper or the like (not shown).

上記に述べた動作を繰り返すことで、巻取り素子を連続的に巻きずれなく形成でき、しかも、帯状材料の移送中に固定ガイドとの間の擦れによる粉塵や傷の発生をなくすことができる。   By repeating the operation described above, the winding element can be continuously formed without being unwound, and the generation of dust and scratches due to rubbing with the fixed guide during the transfer of the belt-shaped material can be eliminated.

なお、上記実施の形態では、帯状材料の移送経路上にある位置決め機構は２個所であったが、適宜増やしてもよい。   In the above embodiment, the number of positioning mechanisms on the belt-shaped material transfer path is two, but may be increased as appropriate.

また、上記実施の形態では、巻軸１軸に対して帯状材料が１つの事例であるが、巻軸１軸に対して上記実施の形態に示す系を複数設け、それらの系を同期運転し、複数の帯状材料からなる巻取り素子を形成することもでき、また、その際、複数の系の中から任意の系を１つないし複数選択して巻取り素子を形成することもでき、またさらに、巻軸を複数備え、適宜いずれかの巻軸１軸を用いて巻取を実施しても良い。   Moreover, in the said embodiment, although a strip | belt-shaped material is one example with respect to 1 axis | shaft of a winding axis, multiple systems shown in the said embodiment are provided with respect to 1 axis | shaft of a winding axis, and these systems are operated synchronously. In addition, a winding element made of a plurality of strip-like materials can be formed, and at that time, one or more arbitrary systems can be selected from the plurality of systems to form a winding element. Further, a plurality of winding shafts may be provided, and winding may be performed using any one winding shaft as appropriate.

また、上記実施の形態では、位置決め機構の１回の位置決め動作と把持機構の１回の往復動作に対して、毎回切断機構により切断動作を行って巻取り素子を形成していたが、それらの動作を複数回行った後、切断機構により切断動作を行うことで、把持機構の可動範囲以上に帯状材料を巻回することもできる。   Further, in the above embodiment, the winding element is formed by performing the cutting operation by the cutting mechanism every time for one positioning operation of the positioning mechanism and one reciprocating operation of the gripping mechanism. By performing the cutting operation by the cutting mechanism after performing the operation a plurality of times, the belt-shaped material can be wound beyond the movable range of the gripping mechanism.

（実施の形態２）
実施の形態２を用いて、本発明の特に請求項３に記載の発明について説明する。 (Embodiment 2)
A second embodiment of the present invention, particularly the invention described in claim 3, will be described.

なお、背景技術と先の実施の形態において説明したものと同じ構成については、同じ符号を用い、説明は省略する。   In addition, the same code | symbol is used about the same structure as what was demonstrated in background art and previous embodiment, and description is abbreviate | omitted.

図４は、本発明の実施の形態２における巻取装置の位置決め機構の斜視図である。   FIG. 4 is a perspective view of the positioning mechanism of the winding device according to the second embodiment of the present invention.

この位置決め機構は、帯状材料１を幅方向の規定された位置に位置決めする開閉式ガイド１６と吸着プレート１８で構成される。   This positioning mechanism includes an openable guide 16 and a suction plate 18 that position the belt-shaped material 1 at a specified position in the width direction.

図４においては、理解しやすいように帯状材料１及び、開閉式ガイド１６の手前側は一部を切断して示している。   In FIG. 4, the band-like material 1 and the front side of the openable guide 16 are partially cut away for easy understanding.

この吸着プレート１８は、スライダ１９により全体が上下方向に可動で、位置決め動作をする時以外は帯状材料１の移送経路から下降した位置に設置されている。   The suction plate 18 is movable in the vertical direction as a whole by the slider 19, and is installed at a position lowered from the transport path of the belt-like material 1 except when performing a positioning operation.

また、この吸着プレート１８は、レバー２０により支点ピン２１を中心としてある一定の範囲で回転可能であり、またスライダ２２により帯状材料１の幅方向にもある一定の範囲で可動である。   The suction plate 18 can be rotated by a lever 20 within a certain range around the fulcrum pin 21, and can be moved by a slider 22 within a certain range in the width direction of the band-shaped material 1.

また、この吸着プレート１８は、ハウジング２３にビス２４で固定された板バネ２５による弾性力で、回転方向と幅方向の各々の中心位置に復帰しようとする。   Further, the suction plate 18 tends to return to the center position in the rotational direction and the width direction by the elastic force of the leaf spring 25 fixed to the housing 23 with screws 24.

さらに、この吸着プレート１８には真空配管２６が接続されており、吸着プレート１８の上面の穴を介して帯状材料１を吸着することができる。   Further, a vacuum pipe 26 is connected to the suction plate 18 so that the belt-like material 1 can be sucked through a hole on the upper surface of the suction plate 18.

この位置決め機構によれば、位置決め動作中において、薄い帯状材料であっても吸着プレートで安定して吸着保持することができる。   According to this positioning mechanism, even a thin belt-like material can be stably sucked and held by the suction plate during the positioning operation.

さらに、この位置決め機構においては、吸着プレート１８は回転および幅方向に可動であるので、帯状材料１を吸着プレート１８で吸着保持した状態で開閉式ガイドによって位置決めし、そして把持機構で帯状材料１を把持しなおすことができる。   Further, in this positioning mechanism, since the suction plate 18 is movable in the rotation and width direction, the belt-like material 1 is positioned by the openable guide while being sucked and held by the suction plate 18, and the belt-like material 1 is held by the gripping mechanism. It can be gripped again.

この動作によれば、安定して帯状材料を位置決めでき、なおかつ、位置決め動作中に帯状材料１が吸着プレート１８上で擦れないので、粉塵や傷の発生がなく帯状材料を位置決めできるという効果を有する。   According to this operation, the band-shaped material can be positioned stably, and the band-shaped material 1 is not rubbed on the suction plate 18 during the positioning operation, so that the band-shaped material can be positioned without generation of dust and scratches. .

また、さらに、この位置決め機構によれば、帯状材料１を安定して吸着保持できるので、実施の形態１で説明した位置決め動作の図２（ｂ）のタイミングで先端送出機構を開放することができる。   Furthermore, according to this positioning mechanism, the belt-like material 1 can be stably adsorbed and held, so that the tip delivery mechanism can be opened at the timing shown in FIG. 2B of the positioning operation described in the first embodiment. .

これにより、先端送出機構が帯状材料１を把持した状態で位置決め動作をする場合に比べて、先端送出機構の把持の影響なく位置決め機構の開閉式ガイドだけで帯状材料１を位置決めできるので、より高精度な位置決めをすることができる。   As a result, the band-shaped material 1 can be positioned with only the open / close guide of the positioning mechanism without being affected by the gripping of the tip-feeding mechanism, compared with the case where the leading-end feeding mechanism performs the positioning operation with the band-shaped material 1 gripped. Accurate positioning can be performed.

（実施の形態３）
実施の形態３を用いて、本発明の特に請求項４に記載の発明について説明する。 (Embodiment 3)
A third embodiment of the present invention, particularly the invention described in claim 4, will be described.

なお、背景技術と先の実施の形態において説明したものと同じ構成については、同じ符号を用い、説明は省略する。   In addition, the same code | symbol is used about the same structure as what was demonstrated in background art and previous embodiment, and description is abbreviate | omitted.

図５は、本発明の実施の形態３における巻取装置の構成概念図である。   FIG. 5 is a conceptual diagram of the configuration of the winding device according to Embodiment 3 of the present invention.

図５において、張力発生機構はサーボモータ２７で駆動されるプーリ２８と、一端をプーリで巻き取られ他端を把持機構に接続される線状部材２９で構成されている。   In FIG. 5, the tension generating mechanism includes a pulley 28 driven by a servo motor 27, and a linear member 29 having one end wound up by the pulley and the other end connected to the gripping mechanism.

これにより弾性係数が一定であるバネ等とは異なり、サーボモータのトルク制御を用いて、帯状材料１の違いに合せて張力を可変にでき、かつ、巻軸の回転中の張力も可変にできるという作用効果を有する。   Thus, unlike a spring having a constant elastic coefficient, the tension can be made variable according to the difference in the belt-like material 1 using the torque control of the servo motor, and the tension during rotation of the winding shaft can be made variable. It has the effect of.

巻取装置における張力制御は巻取り素子の品質に関わる重要なポイントであり、その制御を可変にできることは非常に有効になる。   The tension control in the winding device is an important point related to the quality of the winding element, and it is very effective to make the control variable.

さらに言えば、回転動力で駆動される巻軸が加速と減速を行う際、把持機構とダンサーローラの慣性や、ローラベアリングの粘性抵抗等によって帯状材料１に加わる張力が変化する為、加速と減速時と定速時のそれぞれの状態において最適な張力は異なるが、この構成であれば巻軸の回転動力と同期してサーボモータのトルク制御を行うことで、帯状材料１に対する張力制御が可能である。   Furthermore, when the winding shaft driven by rotational power accelerates and decelerates, the tension applied to the belt-like material 1 changes due to the inertia of the gripping mechanism and the dancer roller, the viscous resistance of the roller bearing, etc. The optimum tension differs in each state at the time and at the constant speed, but with this configuration, the tension control on the belt-like material 1 can be performed by controlling the torque of the servo motor in synchronization with the rotational power of the winding shaft. is there.

本発明にかかる巻取装置およびその方法は、巻取り素子の巻きずれがなく、しかも、帯状材料の移送中に固定ガイドとの間の擦れによる粉塵や傷の発生をなくすことができるという効果を有し、電子機器に使用される電子部品であるアルミ電解コンデンサ、電池等の製造に使用される巻取装置などの用途として有用である。   The winding device and the method according to the present invention have the effect that there is no winding displacement of the winding element, and dust and scratches due to rubbing with the fixed guide can be eliminated during the transfer of the belt-shaped material. It is useful for applications such as an aluminum electrolytic capacitor, which is an electronic component used for electronic equipment, and a winding device used for manufacturing batteries.
