Description

本発明は、例えば二次電池等に内蔵される巻回素子を得るための巻取装置に関する。   The present invention relates to a winding device for obtaining a winding element built in, for example, a secondary battery.

例えば、リチウムイオン電池等の二次電池として用いられる電池素子は、正極活物質が塗布された正極シートと、負極活物質が塗布された負極シートとが、絶縁素材からなるセパレータシートを介して重ね合わされた状態で巻回されて製造される。   For example, in a battery element used as a secondary battery such as a lithium ion battery, a positive electrode sheet coated with a positive electrode active material and a negative electrode sheet coated with a negative electrode active material are overlapped via a separator sheet made of an insulating material. It is wound and manufactured in the state where it was made.

当該電池素子を製造する巻取装置においては、ロール状に巻回された原反から供給される上記各シートがそれぞれ別個の搬送路に沿って搬送され、最終的には各搬送路に設けられた供給機構によって随時、巻取機構へと送り出される。そして、巻取機構の巻芯に対し上記各シートを巻取ることで、電池素子が完成する。   In the winding device for manufacturing the battery element, each of the sheets supplied from the roll wound in a roll is conveyed along a separate conveyance path, and finally provided in each conveyance path. It is sent to the winding mechanism at any time by the feeding mechanism. And a battery element is completed by winding said each sheet | seat with respect to the core of a winding mechanism.

ところが、各シートの巻取りに際し、各シートが蛇行(幅方向への位置ズレ）を起こしてしまうことが懸念される。シートが蛇行した状態で巻取られてしまうと、製品の品質低下を招く。   However, there is a concern that each sheet may meander (position shift in the width direction) when winding each sheet. If the sheet is wound in a meandering state, the quality of the product is deteriorated.

これに対し、巻取機構の近傍に蛇行補正機構を設けて蛇行補正する技術（例えば、特許文献１参照）や、原反を軸方向へ動かし蛇行補正する技術（例えば、特許文献２参照）などが開示されている。   On the other hand, a technique for correcting meandering by providing a meandering correction mechanism in the vicinity of the winding mechanism (for example, see Patent Document 1), a technique for correcting meandering by moving an original fabric in an axial direction (for example, see Patent Document 2), etc. Is disclosed.

When the sheet 92 itself has a habit (warp in the width direction, etc.) or the pass line is misaligned, it is corrected at the position of the original fabric 96 or the meandering correction mechanism 97. Even if it does, there exists a possibility that the position shift | offset | difference 99 may generate | occur | produce in the step in which the sheet | seat 92 is finally wound up by the core 98.

以下に、一実施形態について図面を参照しつつ説明する。   Hereinafter, an embodiment will be described with reference to the drawings.

まず、本実施形態の巻取装置によって得られる巻回素子としてのリチウムイオン電池素子の構成について説明する。図１に示すように、リチウムイオン電池素子（以下、「電池素子」と称す）１は、筒状の巻芯コア２に対して、２枚のセパレータシート３，４と正電極シート５と負電極シート６とによって構成される帯状体７が巻回されることで構成されている。尚、図１においては、説明の便宜上、セパレータシート３，４、正電極シート５、及び、負電極シート６の相互の間隔をあけて示している箇所がある。   First, the structure of the lithium ion battery element as a winding element obtained by the winding device of this embodiment will be described. As shown in FIG. 1, a lithium ion battery element (hereinafter referred to as “battery element”) 1 has two separator sheets 3 and 4, a positive electrode sheet 5, and a negative electrode with respect to a cylindrical core core 2. A belt-like body 7 constituted by the electrode sheet 6 is wound. In FIG. 1, for convenience of explanation, there are places where the separator sheets 3 and 4, the positive electrode sheet 5, and the negative electrode sheet 6 are spaced apart from each other.

本実施形態において、巻芯コア２は、十分な剛性を有する材料（例えば、アルミニウム等の金属素材やポリプロピレン（ＰＰ）等の樹脂素材）により形成されている。また、当該巻芯コア２は、断面非円形状（本実施形態では、断面正方形状）の挿通孔８を有している（図３等参照）。   In the present embodiment, the core core 2 is formed of a material having sufficient rigidity (for example, a metal material such as aluminum or a resin material such as polypropylene (PP)). Moreover, the said core core 2 has the penetration hole 8 of cross-sectional non-circular shape (this embodiment square cross-section) (refer FIG. 3 etc.).

セパレータシート３，４は、巻芯コア２の長手方向に沿った長さと同一の幅を有するものであり、異なる電極シート５，６同士が互いに接触して短絡を起こしてしまうのを防止すべく絶縁体、特に本実施形態ではＰＰにより構成されている。   The separator sheets 3 and 4 have the same width as the length along the longitudinal direction of the core core 2, so as to prevent different electrode sheets 5 and 6 from contacting each other and causing a short circuit. Insulators, in particular in the present embodiment, are made of PP.

正電極シート５及び負電極シート６もまた、セパレータシート３，４と同様、巻芯コア２の長手方向に沿った長さとほぼ同一の幅を有するものである。本実施形態において、正電極シート５及び負電極シート６は、金属製の薄板よりなり、その表裏両面には図示しない活物質が塗布されている。そして、当該活物質を介して、正電極シート５及び負電極シート６間におけるイオン交換ができるようになっている。より詳しくは、充電時には、正電極シート５側から負電極シート６側へイオンが移動し、反対に、放電時には、負電極シート６側から正電極シート５側へとイオンが移動する。また、正電極シート５の幅方向一端縁からは図示しない複数の正極リードが延出するとともに、負電極シート６の幅方向他端縁からは図示しない複数の負極リードが延出している。   Similarly to the separator sheets 3 and 4, the positive electrode sheet 5 and the negative electrode sheet 6 also have substantially the same width as the length along the longitudinal direction of the core core 2. In this embodiment, the positive electrode sheet 5 and the negative electrode sheet 6 are made of a thin metal plate, and an active material (not shown) is applied to both front and back surfaces. And the ion exchange between the positive electrode sheet 5 and the negative electrode sheet 6 can be performed through the active material. More specifically, during charging, ions move from the positive electrode sheet 5 side to the negative electrode sheet 6 side, and conversely, during discharging, ions move from the negative electrode sheet 6 side to the positive electrode sheet 5 side. A plurality of positive leads (not shown) extend from one edge of the positive electrode sheet 5 in the width direction, and a plurality of negative leads (not shown) extend from the other edge of the negative electrode sheet 6 in the width direction.

リチウムイオン電池を得るに際しては、前記電池素子１が金属製で筒状をなす電池容器（図示せず）内に配設されるとともに、前記正極リード及び負極リードがそれぞれまとめられる。そして、まとめられた正極リードを正極端子部品（図示せず）に接続するとともに、同じくまとめられた負極リードを負極端子部品（図示せず）に接続し、両端子部品を前記電気容器の両端開口に設けることで、リチウムイオン電池を得ることができる。   In obtaining a lithium ion battery, the battery element 1 is placed in a cylindrical battery container (not shown) made of metal, and the positive electrode lead and the negative electrode lead are combined. Then, the combined positive lead is connected to a positive terminal component (not shown), the negative electrode lead is also connected to a negative terminal component (not shown), and both terminal components are opened at both ends of the electric container. By providing in, a lithium ion battery can be obtained.

次に、前記電池素子１を製造するための巻取装置１１について説明する。図２に示すように、巻取装置１１は、回転可能に設けられたターレット１２を備えている。該ターレット１２は、２枚の円盤状のテーブル１４，１５が相対向するようにして構成されており、両テーブル１４，１５間に跨って、回転体２０が、テーブル１４，１５の中心を対称中心として２つ設けられている。尚、両テーブル１４，１５（ターレット１２）は時計回りに回転可能に構成されているとともに、両テーブル１４，１５が同期回転するように設定されている。これにより、各回転体２０が着脱ポジションＰ１及び巻取ポジションＰ２間を移動することができるようになっている。尚、両テーブル１４，１５は、１８０°ずつ反転可能となっていてもよい。   Next, the winding device 11 for manufacturing the battery element 1 will be described. As shown in FIG. 2, the winding device 11 includes a turret 12 that is rotatably provided. The turret 12 is configured such that two disk-shaped tables 14 and 15 are opposed to each other, and the rotating body 20 is symmetric about the centers of the tables 14 and 15 across the tables 14 and 15. Two centers are provided. Both tables 14 and 15 (turret 12) are configured to rotate clockwise and are set so that both tables 14 and 15 rotate synchronously. Thereby, each rotary body 20 can move between the attachment / detachment position P1 and the winding position P2. Note that the tables 14 and 15 may be reversible by 180 °.

図３にしたがって巻回手段としての回転体２０の一例について説明すると、回転体２０は、軸線Ｃ方向に延び、軸線Ｃ方向一端側のテーブル１４から他端側のテーブル１５に向けて突出する回転軸としての巻芯２１と、前記軸線Ｃ方向に延び、軸線Ｃ方向他端側のテーブル１５から一端側のテーブル１４に向けて突出する巻芯受け３１とから構成されている。   An example of the rotating body 20 as the winding means will be described with reference to FIG. 3. The rotating body 20 rotates in the direction of the axis C and protrudes from the table 14 on one end side in the axis C direction toward the table 15 on the other end side. A core 21 as a shaft and a core receiver 31 extending in the axis C direction and projecting from the table 15 on the other end side in the axis C direction toward the table 14 on the one end side.

前記巻芯２１は、全体として棒状をなしており、軸線Ｃ方向他端側に延びる基部２２と、当該基部２２から軸線Ｃ方向他端側に延びる装着部２３と、前記基部２２及び装着部２３間に形成されたテーパ段差部２４とから構成されている。また、基部２２、装着部２３、及び、テーパ段差部２４の中心軸はそれぞれ前記軸線Ｃと一致している。   The winding core 21 has a rod shape as a whole, and includes a base portion 22 extending to the other end side in the axis C direction, a mounting portion 23 extending from the base portion 22 to the other end side in the axis C direction, and the base portion 22 and the mounting portion 23. It comprises a taper stepped portion 24 formed therebetween. Further, the central axes of the base portion 22, the mounting portion 23, and the taper step portion 24 coincide with the axis C.

前記基部２２は、円柱状をなし、図示しない駆動手段によって、前記テーブル１４に対し軸線Ｃ方向に沿って相対移動可能（出没可能）に構成されている。これにより、前記巻芯受け３１に対して巻芯２１が接離可能となっている。加えて、基部２２は、図示しない回転駆動手段（例えば、モータ）によって、軸線Ｃを回転軸としてテーブル１４に対して相対回転可能となっており、ひいては巻芯２１全体が軸線Ｃを回転軸として相対回転可能となっている。すなわち、回転駆動手段は帯状体７を巻取る際の巻取動力として機能する。   The base portion 22 has a cylindrical shape and is configured to be movable relative to the table 14 along the direction of the axis C (can be moved in and out) by a driving unit (not shown). Thereby, the core 21 can be brought into contact with and separated from the core receiver 31. In addition, the base 22 can be rotated relative to the table 14 with the axis C as the rotation axis by a rotation driving means (for example, a motor) (not shown), and the entire core 21 has the axis C as the rotation axis. Relative rotation is possible. That is, the rotation driving means functions as winding power when winding the belt-like body 7.

前記装着部２３は、電池素子１の製造時において、前記巻芯コア２がその外周部分に装着されるものである。当該装着部２３は、棒状をなすとともに、前記巻芯コア２の挿通孔８の断面形状に対応すべく断面非円形状（本実施形態では、断面正方形状）に形成されている。さらに、装着部２３は、前記基部２２よりも細化されており、また、装着部２３の先端側面部には、軸線Ｃ方向へと延びる一対の先割れ部２５が形成されている。加えて、当該先割れ部２５の内周部分には、後述する受けピン３３を嵌合可能な図示しない嵌合凹部が形成されている。   The mounting portion 23 is for mounting the core 2 on the outer peripheral portion when the battery element 1 is manufactured. The mounting portion 23 has a bar shape and is formed in a non-circular cross section (in this embodiment, a square cross section) to correspond to the cross sectional shape of the insertion hole 8 of the core core 2. Further, the mounting portion 23 is made thinner than the base portion 22, and a pair of tip crack portions 25 extending in the direction of the axis C are formed on the tip side surface portion of the mounting portion 23. In addition, a fitting recess (not shown) capable of fitting a later-described receiving pin 33 is formed in the inner peripheral portion of the tip crack portion 25.

一方、前記巻芯受け３１は、円柱状をなす支持部３２と、当該支持部３２に一体形成され、軸線Ｃ方向一端側に向けて突出する受けピン３３と、当該受けピン３３の外周側に設けられ、先端筒状の受け部３４とを備えている。尚、支持部３２、受けピン３３、及び、受け部３４のそれぞれの中心軸は、前記軸線Ｃと一致している。   On the other hand, the core receiver 31 has a columnar support portion 32, a receiving pin 33 that is integrally formed with the support portion 32 and protrudes toward one end side in the axis C direction, and an outer peripheral side of the receiving pin 33. And a tip-shaped cylindrical receiving portion 34. The central axes of the support portion 32, the receiving pin 33, and the receiving portion 34 are coincident with the axis C.

前記支持部３２は、前記テーブル１５に対して軸線Ｃを回転軸として相対回転（本実施形態では、自由回転）可能、かつ、軸線Ｃ方向に相対移動不能に支持されている。   The support portion 32 is supported relative to the table 15 so as to be capable of relative rotation (free rotation in the present embodiment) about the axis C as a rotation axis, and relatively unmovable in the direction of the axis C.

前記受けピン３３は、円柱状をなすとともに、その外周面の大部分が軸線Ｃと略平行となるように構成されている。当該受けピン３３は、前記受け部３４の内側に配設されており、また、その外径は、前記嵌合凹部の内径と同径或いは若干大径となるように構成されている。尚、受けピン３３は、前記嵌合凹部への嵌合をより容易なものとすべく、その先端部分が先細り形状となっている。   The receiving pin 33 has a cylindrical shape and is configured so that most of the outer peripheral surface thereof is substantially parallel to the axis C. The receiving pin 33 is disposed on the inner side of the receiving portion 34, and has an outer diameter that is the same as or slightly larger than the inner diameter of the fitting recess. The receiving pin 33 has a tapered tip at its tip so that the fitting into the fitting recess is easier.

前記受け部３４は、前記巻芯コア２の外径と略等しい外径を有しており、その先端面が前記巻芯コア２の一端面と当接可能な被当接面３５となっている。また、受け部３４と受けピン３３との間の環状空間は、装着部２３の先端部を収容可能な収容凹部３６となっており、前記受けピン３３が、前記嵌合凹部に嵌合された際には、装着部２３の先端部が前記収容凹部３６に収容されるようになっている。   The receiving portion 34 has an outer diameter that is substantially equal to the outer diameter of the core core 2, and a tip surface thereof serves as a contact surface 35 that can abut one end surface of the core core 2. Yes. An annular space between the receiving portion 34 and the receiving pin 33 is an accommodating recess 36 that can accommodate the tip of the mounting portion 23, and the receiving pin 33 is fitted in the fitting recess. In this case, the tip of the mounting portion 23 is accommodated in the accommodation recess 36.

上記のように構成されている回転体２０にあっては、後記する着脱装置１３によって、装着部２３に巻芯コア２が取付けられる。そして、基部２２を軸線Ｃ方向に沿って他端側（テーブル１５側）へと相対移動させることで、受けピン３３が前記嵌合凹部に嵌合されるとともに、受け部３４の収容凹部３６に対して装着部２３の先端部が挿入される。このとき、装着部２３の先端部が受けピン３３によって外周側へ広げられることとなり、ひいては巻芯コア２の他端部が前記装着部２３によって内周側から保持されることとなる。併せて、巻芯コア２の一端部が、前記テーパ段差部２４に当接・保持されることとなる。さらに、巻芯コア２の他端の当接面が、受け部３４の被当接面３５に当接する。このようにして巻芯コア２が、回転体２０に装着される。   In the rotating body 20 configured as described above, the core core 2 is attached to the mounting portion 23 by the attaching / detaching device 13 described later. Then, by moving the base portion 22 relative to the other end side (table 15 side) along the axis C direction, the receiving pin 33 is fitted into the fitting concave portion, and the receiving concave portion 36 of the receiving portion 34 is fitted into the receiving concave portion 36. On the other hand, the tip of the mounting portion 23 is inserted. At this time, the front end portion of the mounting portion 23 is expanded to the outer peripheral side by the receiving pin 33, and the other end portion of the winding core 2 is held by the mounting portion 23 from the inner peripheral side. At the same time, one end of the core 2 is brought into contact with and held by the tapered stepped portion 24. Furthermore, the contact surface at the other end of the core 2 contacts the contact surface 35 of the receiving portion 34. In this way, the core core 2 is attached to the rotating body 20.

説明を図２の巻取装置１１に戻す。前記２つの回転体２０が、前記ターレット１２の回動により、着脱ポジションＰ１（図の右側位置）と、巻取ポジションＰ２（図の左側位置）との間を移動可能である点については上述したが、本実施形態では、着脱ポジションＰ１に対応して、後述する巻芯コア２の取付及び電池素子１の取外を行うための着脱装置１３が設けられている。   The description returns to the winding device 11 of FIG. As described above, the two rotating bodies 20 can move between the attachment / detachment position P1 (right position in the figure) and the winding position P2 (left position in the figure) by the rotation of the turret 12. However, in the present embodiment, an attachment / detachment device 13 for attaching a core core 2 (to be described later) and removing the battery element 1 is provided corresponding to the attachment / detachment position P1.

また、巻取ポジションＰ２は、前記巻芯コア２に対し帯状体７を巻回するポジションであって、当該巻取ポジションＰ２に対応して、帯状体７を供給するための帯状体供給機構が設けられている。より具体的には、帯状体供給機構は、２枚のセパレータシート３，４をそれぞれ巻取ポジションＰ２に位置する回転体２０の方へ供給するセパレータ供給機構と、正電極シート５を回転体２０の方へ供給する正電極シート供給機構と、負電極シート６を回転体２０の方へ供給する負電極シート供給機構とを備えている（図２においてはいずれも図示を省略する）。いずれの供給機構も、ロール状に巻回された原反から帯状体７（セパレータシート３，４や電極シート５，６）を引き出して、回転体２０の方へ供給することができるよう構成されているが、ここでは、正電極シート供給機構及び負電極シート供給機構の構成に特徴があるので、次には、正電極シート供給機構を代表例として、図４を参照しつつ、詳細を説明することとする。   The winding position P2 is a position for winding the belt-like body 7 around the core core 2, and a belt-like body supply mechanism for supplying the belt-like body 7 corresponding to the winding position P2. Is provided. More specifically, the belt-like body supply mechanism includes a separator supply mechanism that supplies the two separator sheets 3 and 4 to the rotating body 20 positioned at the winding position P2, and a positive electrode sheet 5 that rotates the rotating body 20. And a negative electrode sheet supply mechanism for supplying the negative electrode sheet 6 toward the rotating body 20 (both are not shown in FIG. 2). Any of the supply mechanisms is configured such that the belt-like body 7 (separator sheets 3 and 4 and electrode sheets 5 and 6) can be drawn out from the raw material wound in a roll shape and supplied to the rotating body 20. However, since the positive electrode sheet supply mechanism and the negative electrode sheet supply mechanism are characterized here, the details will be described below with reference to FIG. 4 using the positive electrode sheet supply mechanism as a representative example. I decided to.

正電極シート供給機構の最上流側においては、正電極シート５がロール状に巻回された原反４０が、支持手段としての支持軸４１にて自由回転可能に支持されている。支持軸４１は、図示しないアクチュエータにより自身の軸線方向に沿って動作可能に構成されている。   On the most upstream side of the positive electrode sheet supply mechanism, an original fabric 40 around which the positive electrode sheet 5 is wound in a roll shape is supported by a support shaft 41 as a support means so as to be freely rotatable. The support shaft 41 is configured to be operable along its own axial direction by an actuator (not shown).

また、原反４０の下流側には、正電極シート５の上下位置に配置され、当該正電極シート５の幅方向の位置ズレを検出する検出手段（第３検出手段）としてのエッジセンサ７２が設けられている。   In addition, an edge sensor 72 serving as a detection unit (third detection unit) that is disposed at the upper and lower positions of the positive electrode sheet 5 and detects a positional shift in the width direction of the positive electrode sheet 5 is provided downstream of the original fabric 40. Is provided.

そして、正電極シート５の巻回中においては、エッジセンサ７２の検出結果と、予め記憶された第２基準値としての原反補正基準値に基づき、前記アクチュエータによって支持軸４１が駆動されることにより、正電極シート５の幅方向の位置ズレが補正される。つまり、支持軸４１等により本実施形態における原反補正手段が構成される。   While the positive electrode sheet 5 is being wound, the support shaft 41 is driven by the actuator based on the detection result of the edge sensor 72 and the original fabric correction reference value as the second reference value stored in advance. Thus, the positional deviation in the width direction of the positive electrode sheet 5 is corrected. That is, the original fabric correcting means in the present embodiment is constituted by the support shaft 41 and the like.

支持軸４１から回転体２０にかけての正電極シート５の供給経路の途中には、張力付与手段４２が設けられている。当該張力付与手段４２は、一対のローラ４３，４４と、両ローラ４３，４４間に設けられた段差ローラ４５とを具備している。   A tension applying means 42 is provided in the middle of the supply path of the positive electrode sheet 5 from the support shaft 41 to the rotating body 20. The tension applying means 42 includes a pair of rollers 43 and 44 and a step roller 45 provided between the rollers 43 and 44.

また、正電極シート５の供給経路の途中において、前記張力付与手段４２の下流側（回転体２０側）には、電極シート供給手段４７が設けられている。電極シート供給手段４７は、把持部としての上下一対のチャック４８を具備している。電極シート供給手段４７は、図示しないチャック用アクチュエータ（例えばモータやシリンダ）を備え、これによりチャック４８が開閉動作可能となっている。   In the middle of the supply path of the positive electrode sheet 5, an electrode sheet supply unit 47 is provided on the downstream side (rotating body 20 side) of the tension applying unit 42. The electrode sheet supply means 47 includes a pair of upper and lower chucks 48 as gripping portions. The electrode sheet supply means 47 includes a chuck actuator (for example, a motor or a cylinder) (not shown), so that the chuck 48 can be opened and closed.

電極シート供給手段４７はまた、前記正電極シート５の供給経路に沿って移動可能に構成されている。より詳しくは、電極シート供給手段４７は、図示しないアクチュエータ（例えばモータ）により、前記回転体２０から相当距離離間した退避位置（図４参照）と、回転体２０に最も接近した最接近位置（図６参照）との間を移動可能に構成されている。前記最接近位置は、チャック４８により把持された正電極シート５の先端部を、回転体２０の回転に基づき巻取開始可能な程度に十分に近い位置である。   The electrode sheet supply means 47 is also configured to be movable along the supply path of the positive electrode sheet 5. More specifically, the electrode sheet supply means 47 is provided with a retracted position (see FIG. 4) separated from the rotating body 20 by a not-shown actuator (for example, a motor) and a closest position (see FIG. 4) closest to the rotating body 20. 6)). The closest approach position is a position that is close enough to start winding the front end portion of the positive electrode sheet 5 held by the chuck 48 based on the rotation of the rotating body 20.

さて、本実施形態では、前記電極シート供給手段４７は、把持部４８以外にも、巻前補正機構５１を具備している。巻前補正機構５１は、正電極シート５の上下位置に配置され、当該正電極シート５の幅方向の位置ズレを検出する検出手段（第１検出手段）としてのエッジセンサ５２と、エッジセンサ５２の検出結果及び予め記憶された第１基準値としての巻前補正基準値を基に正電極シート５の幅方向の位置ズレを補正する巻前補正手段としての補正部５３と、前記補正部５３を動作させるアクチュエータ（図示せず）とを備えている。本実施形態では、図５に示すように、補正部５３は、上下一対のローラ５４，５５により構成されるとともに、前記アクチュエータによって、下側のローラ５４の下部中央のピボットセンターαを回動中心として同図矢印方向に回動可能となっている。これにより、正電極シート５の位置ズレ（蛇行）が補正されるようになっている。   In the present embodiment, the electrode sheet supply means 47 includes a pre-winding correction mechanism 51 in addition to the grip portion 48. The pre-winding correction mechanism 51 is disposed at the upper and lower positions of the positive electrode sheet 5, and an edge sensor 52 as detection means (first detection means) for detecting a positional deviation in the width direction of the positive electrode sheet 5, and the edge sensor 52. The correction unit 53 as a pre-winding correction unit that corrects the positional deviation in the width direction of the positive electrode sheet 5 based on the detection result of the above and the pre-winding correction reference value as the first reference value stored in advance, and the correction unit 53 And an actuator (not shown). In the present embodiment, as shown in FIG. 5, the correction unit 53 is composed of a pair of upper and lower rollers 54 and 55, and a pivot center α at the lower center of the lower roller 54 is pivoted by the actuator. As shown in FIG. Thereby, the positional deviation (meandering) of the positive electrode sheet 5 is corrected.

さらに、正電極シート５の供給経路の途中において、前記電極シート供給手段４７の下流側（回転体２０側）には、正電極シート５を切断する切断手段６１が設けられている。切断手段６１は、例えば正電極シート５の下側に位置する台座部６２と、上側に位置する刃部６３とを備えている。但し、切断手段６１は、前記電極シート供給手段４７の移動を阻害しない位置に設けられているか、又は、切断位置と、電極シート供給手段４７の移動を阻害しない退避位置との間を移動可能に設けられている。   Further, a cutting means 61 for cutting the positive electrode sheet 5 is provided on the downstream side (rotary body 20 side) of the electrode sheet supply means 47 in the middle of the supply path of the positive electrode sheet 5. The cutting means 61 includes, for example, a pedestal portion 62 positioned on the lower side of the positive electrode sheet 5 and a blade portion 63 positioned on the upper side. However, the cutting means 61 is provided at a position that does not hinder the movement of the electrode sheet supply means 47, or is movable between a cutting position and a retracted position that does not hinder the movement of the electrode sheet supply means 47. Is provided.

また、切断手段６１の下流側（回転体２０側）には、正電極シート５の上下位置に配置され、当該正電極シート５の幅方向の位置ズレを検出する検出手段（第２検出手段）としてのエッジセンサ８２が設けられている。   Further, on the downstream side (rotating body 20 side) of the cutting means 61, a detection means (second detection means) that is disposed at the vertical position of the positive electrode sheet 5 and detects a positional deviation in the width direction of the positive electrode sheet 5. An edge sensor 82 is provided.

以上が正電極シート供給機構の説明であるが、負電極シート６を回転体２０の方へ供給する負電極シート供給機構についても上記同様の構成を具備している。また、セパレータ供給機構についても、蛇行補正に係る各種機構など、基本的には上記と同様の構成を具備している。   The above is the description of the positive electrode sheet supply mechanism, but the negative electrode sheet supply mechanism that supplies the negative electrode sheet 6 toward the rotating body 20 has the same configuration as described above. Also, the separator supply mechanism basically has the same configuration as described above, such as various mechanisms related to meandering correction.

また、本実施形態では、前記巻取ポジションＰ２に対応して、図示しないセパレータ固着手段が設けられている。セパレータ固着手段は、巻回の初期段階において、例えば、熱溶着により、セパレータシート３，４の先端部分を巻芯コア２の表面に対し取着可能に構成されている。勿論、単に接着テープ等を用いてセパレータシート３，４の先端部分を巻芯コア２の表面に対し貼付ける構成であっても差し支えない。   In the present embodiment, a separator fixing means (not shown) is provided corresponding to the winding position P2. The separator fixing means is configured to be able to attach the leading end portions of the separator sheets 3 and 4 to the surface of the core core 2 by, for example, heat welding in the initial stage of winding. Of course, it is possible to use a configuration in which the tip portions of the separator sheets 3 and 4 are simply attached to the surface of the core core 2 using an adhesive tape or the like.

なお、上記回転体２０や各シート供給機構など、巻取装置１１内の各種機構は、図示しない制御装置により動作制御される構成となっている。つまり、当該制御装置が本実施形態における基準値補正手段、第１基準値補正手段及び第２基準値補正手段を構成することとなる。   The various mechanisms in the winding device 11 such as the rotating body 20 and the sheet supply mechanisms are configured to be controlled by a control device (not shown). That is, the control device constitutes the reference value correction means, the first reference value correction means, and the second reference value correction means in the present embodiment.

次に、上述した巻取装置１１を用いて、電池素子１を製造するための方法について、特に、電極シート（図６〜図１０等では正電極シート５）の供給に着目しつつ説明する。   Next, a method for manufacturing the battery element 1 using the above-described winding device 11 will be described with particular attention paid to supply of an electrode sheet (positive electrode sheet 5 in FIGS. 6 to 10 and the like).

まず、ターレット１２を時計回りに半回転させることで、一方の回転体２０を着脱ポジションＰ１へと移動させる。このとき、他方の回転体２０は巻取ポジションＰ２に位置することとなる。例えば、それまで巻取ポジションＰ２に位置しており帯状体７の巻回がほぼ完了した回転体２０が、着脱ポジションＰ１へと移動させられる。一方、それまで着脱ポジションＰ１に位置しており新たな巻芯コア２の装着された回転体２０が巻取ポジションＰ２へと移動させられる。   First, one rotator 20 is moved to the attachment / detachment position P1 by rotating the turret 12 halfway clockwise. At this time, the other rotating body 20 is positioned at the winding position P2. For example, the rotating body 20 that has been positioned at the winding position P <b> 2 until the winding of the belt-like body 7 is almost completed is moved to the attachment / detachment position P <b> 1. On the other hand, the rotating body 20 that has been positioned at the attachment / detachment position P1 and on which the new core core 2 is mounted is moved to the winding position P2.

かかる巻取ポジションＰ２に位置する回転体２０においては、巻芯コア２が装着されているのであるが、当初、当該巻芯コア２には何も巻き付けられていない。この状態において、先ず上述したセパレータ固着手段により、セパレータシート３，４の先端部分が巻芯コア２の表面に対し取着固定される。   In the rotating body 20 located at the winding position P2, the core core 2 is mounted, but nothing is wound around the core core 2 at the beginning. In this state, first, the tip end portions of the separator sheets 3 and 4 are attached and fixed to the surface of the core core 2 by the separator fixing means described above.

続いて、当該巻取ポジションＰ２においては、回転体２０（巻芯２１）の回転が行われる。そして、所定タイミングが到来したならば、正電極シート供給機構及び負電極シート供給機構の各電極シート供給手段４７が作動させられ、各電極シート５，６が巻芯コア２の方に向けて供給される。   Subsequently, at the winding position P2, the rotating body 20 (core 21) is rotated. When the predetermined timing arrives, the respective electrode sheet supply means 47 of the positive electrode sheet supply mechanism and the negative electrode sheet supply mechanism are operated, and the respective electrode sheets 5 and 6 are supplied toward the core core 2. Is done.

より詳しくは、それまで前記チャック４８によって先端部が把持された各電極シート５，６が、例えば図６に示すように、電極シート供給手段４７（チャック４８）が回転体２０の方へ移動させられることで、巻芯コア２の方に向けて供給される。これにより、図７に示すように、各電極シート５，６の先端が、各セパレータシート３，４で挟み込まれることとなり、正電極シート５及び負電極シート６が、それぞれ各セパレータシート３，４を介して互いに絶縁状態で巻き取られ始めることとなる。そして、正電極シート５及び負電極シート６の巻取りが開始されたならば、図８に示すように、チャック４８が開かれる。これにより、正電極シート５及び負電極シート６は、前記張力付与手段４２にて所定の張力を付与されながら、セパレータシート３，４とともに巻き取られることとなる。尚、前記チャック４８の開放に伴い、図９に示すように、電極シート供給手段４７は幾分上流側（回転体２０から離間する側）へ移動させられる。これにより、巻取り量が増大した場合でも、巻回素子がチャック２８等に接触し、巻取りが阻害されてしまうといった事態が回避される。勿論、巻取り量の増大に伴って徐々に上流側に移動するよう構成してもよい。但し、この巻取りの最中においては、電極シート供給手段４７が、前記退避位置よりも回転体２０に近い側に位置するよう配置される。   More specifically, each of the electrode sheets 5 and 6 whose tip portions have been gripped by the chuck 48 until then are moved by the electrode sheet supply means 47 (chuck 48) toward the rotating body 20 as shown in FIG. By being done, it supplies toward the core core 2. As a result, as shown in FIG. 7, the tips of the electrode sheets 5 and 6 are sandwiched between the separator sheets 3 and 4, and the positive electrode sheet 5 and the negative electrode sheet 6 are respectively connected to the separator sheets 3 and 4. It will begin to wind up in an insulated state from each other. When the winding of the positive electrode sheet 5 and the negative electrode sheet 6 is started, the chuck 48 is opened as shown in FIG. Thus, the positive electrode sheet 5 and the negative electrode sheet 6 are wound together with the separator sheets 3 and 4 while being given a predetermined tension by the tension applying means 42. As the chuck 48 is opened, the electrode sheet supply means 47 is moved somewhat upstream (side away from the rotating body 20) as shown in FIG. As a result, even when the winding amount increases, a situation in which the winding element comes into contact with the chuck 28 and the like and the winding is hindered is avoided. Of course, you may comprise so that it may move to an upstream side gradually with the increase in winding amount. However, during the winding, the electrode sheet supply means 47 is arranged so as to be positioned closer to the rotating body 20 than the retracted position.

帯状体７の巻回がほぼ完了したならば、回転体２０の回転が一旦停止された上で、図１０に示すように、正電極シート５及び負電極シート６が前記切断手段６１で切断される。前記切断に際しては、チャック４８が閉状態とされ、これにより、次回巻取り用の正電極シート５及び負電極シート６の先端部分がチャック４８で把持されることとなる。その後、回転体２０を幾らか回転させた後、セパレータシート３，４についても切断する。そして、切断された残りの帯状体７が完全に巻き取られ、外周側のセパレータシート３，４に関しテープ止めが施されることで巻取が完了する。   If the winding of the belt-like body 7 is almost completed, the rotation of the rotating body 20 is once stopped, and then the positive electrode sheet 5 and the negative electrode sheet 6 are cut by the cutting means 61 as shown in FIG. The At the time of the cutting, the chuck 48 is closed, so that the leading end portions of the positive electrode sheet 5 and the negative electrode sheet 6 for next winding are gripped by the chuck 48. Then, after rotating the rotary body 20 to some extent, the separator sheets 3 and 4 are also cut. Then, the remaining cut strip 7 is completely wound up, and the winding is completed by tape-fastening the separator sheets 3 and 4 on the outer peripheral side.

その後、前記回転体２０等を着脱ポジションＰ１へと移動させた上で、巻芯２１を巻芯受け３１から離間する方向へと相対移動させ、前記受けピン３３を嵌合凹部から抜き外すことで、装着部２３による巻芯コア２の保持力が解除されることとなる。その上で、帯状体７の巻回された巻芯コア２を、巻芯コア２ごと装着部２３から取り外すことで電池素子１が得られる。   Then, after moving the rotating body 20 and the like to the attachment / detachment position P1, the core 21 is relatively moved in a direction away from the core receiver 31, and the receiving pin 33 is removed from the fitting recess. Thus, the holding force of the core 2 by the mounting portion 23 is released. After that, the battery element 1 is obtained by removing the wound core core 2 around which the belt-like body 7 is wound together with the wound core 2 from the mounting portion 23.

次に電子素子１の巻回中に各シート供給機構にて行われる蛇行補正の手順について正電極シート５の場合を例に説明する。まず、巻前補正機構５１にて行われる巻前蛇行補正の手順について説明する。   Next, the meandering correction procedure performed by each sheet supply mechanism during winding of the electronic element 1 will be described by taking the case of the positive electrode sheet 5 as an example. First, the procedure of the pre-winding meander correction performed by the pre-winding correction mechanism 51 will be described.

制御装置は、電池素子１の巻回中、随時、エッジセンサ５２により正電極シート５のエッジ位置を検出しつつ、当該エッジ位置と予め記憶した巻前補正基準値（第１基準値）との差を求め、当該差分（正電極シート５の補正量）に相当する補正部５３の駆動量（駆動角度）を算出する。そして、当該演算結果に基づいた所定角度分、補正部５３を傾けることにより、正電極シート５の位置ズレ（蛇行）を補正する。   While the battery element 1 is being wound, the control device detects the edge position of the positive electrode sheet 5 by the edge sensor 52 at any time, and calculates the edge position and the pre-winding correction reference value (first reference value) stored in advance. The difference is obtained, and the drive amount (drive angle) of the correction unit 53 corresponding to the difference (correction amount of the positive electrode sheet 5) is calculated. Then, the position shift (meander) of the positive electrode sheet 5 is corrected by tilting the correction unit 53 by a predetermined angle based on the calculation result.

同時に、制御装置は、電池素子１の巻回中におけるエッジセンサ８２の検出結果（正電極シート５の幅方向のエッジ位置）を順次、所定の記憶手段に記憶していく。そして、電池素子１の巻回が終了すると、当該電池素子１の巻回中に記憶された１素子分の正電極シート５の幅方向のエッジ位置の平均値を算出する。続いて、当該平均値と、記憶されている巻前補正基準値との差を求め、当該差分を当該巻前補正基準値に加算又は減算し、その値を新たな巻前補正基準値として記憶する。これにより、次回の巻前蛇行補正時には、当該巻前補正基準値が新たな基準値として用いられることとなる。   At the same time, the control device sequentially stores the detection result of the edge sensor 82 during the winding of the battery element 1 (the edge position in the width direction of the positive electrode sheet 5) in a predetermined storage unit. When the winding of the battery element 1 is completed, the average value of the edge positions in the width direction of the positive electrode sheet 5 for one element stored during the winding of the battery element 1 is calculated. Subsequently, a difference between the average value and the stored pre-winding correction reference value is obtained, and the difference is added to or subtracted from the pre-winding correction reference value, and the value is stored as a new pre-winding correction reference value. To do. As a result, at the next pre-winding meandering correction, the pre-winding correction reference value is used as a new reference value.

次に、原反４０の支持軸４１にて行われる原反蛇行補正の手順について説明する。   Next, the procedure for correcting the meandering of the material performed on the support shaft 41 of the material 40 will be described.

制御装置は、電池素子１の巻回中、随時、エッジセンサ７２により正電極シート５のエッジ位置を検出しつつ、当該エッジ位置と予め記憶した原反補正基準値（第２基準値）との差を求める。そして、当該差分（正電極シート５の補正量）に相当する分、支持軸４１を軸方向へ動かし、正電極シート５の位置ズレ（蛇行）を補正する。   While the battery element 1 is being wound, the control device detects the edge position of the positive electrode sheet 5 by the edge sensor 72 as needed, and calculates the edge position and the previously stored original fabric correction reference value (second reference value). Find the difference. Then, the support shaft 41 is moved in the axial direction by an amount corresponding to the difference (correction amount of the positive electrode sheet 5), and the positional deviation (meandering) of the positive electrode sheet 5 is corrected.

同時に、制御装置は、電池素子１の巻回中の補正部５３の駆動量を順次、所定の記憶手段に記憶していく。そして、電池素子１の巻回が終了すると、前記記憶手段に記憶された過去複数回の電池素子１の巻回に係る補正部５３の駆動量の平均値を算出するとともに、当該平均値を、支持軸４１の駆動量（軸方向への変位量）に相当する値に換算する。続いて、当該換算した値を、記憶されている原反補正基準値に加算又は減算し、当該値を新たな原反補正基準値として記憶する。これにより、次回の原反蛇行補正時には、当該原反補正基準値が新たな基準値として用いられることとなる。   At the same time, the control device sequentially stores the drive amount of the correction unit 53 during winding of the battery element 1 in a predetermined storage unit. Then, when the winding of the battery element 1 is completed, the average value of the driving amount of the correction unit 53 related to the past winding of the battery element 1 stored in the storage unit is calculated, and the average value is calculated as follows: The value is converted into a value corresponding to the driving amount (displacement amount in the axial direction) of the support shaft 41. Subsequently, the converted value is added to or subtracted from the stored original correction reference value, and the value is stored as a new original correction reference value. As a result, at the next original sheet meander correction, the original sheet correction reference value is used as a new reference value.

以上詳述したように、本実施形態では、巻前蛇行補正及び原反蛇行補正が行われることにより、正電極シート５等の幅方向の位置ズレを補正することができる。   As described in detail above, in the present embodiment, the pre-winding meandering correction and the original fabric meandering correction are performed, whereby the positional deviation in the width direction of the positive electrode sheet 5 or the like can be corrected.

さらに、回転体２０近傍に設けられたエッジセンサ８２の検出結果をフィードバックして、巻前蛇行補正に係る巻前補正基準値を補正することにより、当該巻前補正基準値と、実際に回転体２０において巻回される正電極シート５等の位置とのズレを低減することができる。これにより、仮に正電極シート５等に幅方向への反り等がある場合であっても、最終的に正電極シート５等が回転体２０に巻取られる段階において位置ズレが発生しにくくなる。結果として、製造される電子素子１の品質の向上を図ることができる。   Further, the detection result of the edge sensor 82 provided in the vicinity of the rotating body 20 is fed back to correct the pre-winding correction reference value related to the pre-winding meandering correction, so that the pre-winding correction reference value and the actual rotating body are corrected. The deviation from the position of the positive electrode sheet 5 or the like wound at 20 can be reduced. As a result, even if the positive electrode sheet 5 or the like has a warp in the width direction or the like, the positional deviation is less likely to occur at the stage where the positive electrode sheet 5 or the like is finally wound around the rotating body 20. As a result, the quality of the manufactured electronic device 1 can be improved.

また、巻前補正機構５１（補正部５３）の駆動量をフィードバックして、原反蛇行補正に係る原反補正基準値を補正することにより、巻前蛇行補正の前段階に予備的な補正を行うことができる。結果として、巻前補正機構５１における補正量を低減させ、巻前補正機構５１や正電極シート５等への負担軽減を図ることができる。ひいては、回転体２０に巻取られる段階での正電極シート５等の位置ズレをさらに低減することができる。   In addition, the amount of drive of the pre-winding correction mechanism 51 (correcting unit 53) is fed back to correct the original fabric correction reference value related to the raw fabric meander correction, thereby performing preliminary correction before the pre-winding meander correction. It can be carried out. As a result, the correction amount in the pre-winding correction mechanism 51 can be reduced, and the burden on the pre-winding correction mechanism 51 and the positive electrode sheet 5 can be reduced. As a result, the positional deviation of the positive electrode sheet 5 or the like at the stage of being wound around the rotating body 20 can be further reduced.
