Description

発明の詳細な説明Detailed Description of the Invention

本発明は電池素子材料の捲回装置に関するものである。  The present invention relates to a winding device for battery element materials.

例えば、リチウム電池等の二次電池は金属集電体に一定の間隔で正極活物質が設けられた塗布部を有する正極集電体と、金属集電体に一定の間隔で負極活物質が設けられた塗布部を有する負極集電体とを備え、この正・負極集電体（電池素子材料）とがセパレーター等絶縁体を介して捲回されたものを電池素子とし、ケース内に収容して構成されている。  For example, a secondary battery such as a lithium battery has a positive electrode current collector having a coating portion in which a positive electrode active material is provided on a metal current collector at regular intervals, and a negative electrode active material on a metal current collector at regular intervals. A negative electrode current collector having a coated portion, and the positive and negative electrode current collectors (battery element material) wound through an insulator such as a separator as a battery element, and accommodated in a case Configured.

このような構成の二次電池素子を得る捲回装置では、それぞれロール状に巻き上げられた正・負極電池素子材料（原反）およびセパレーター等絶縁体を捲回部まで間欠的かつ断続的に送り出し、捲回部巻芯によって捲回し、正・負極電池素子材料およびセパレーター等絶縁体を所定の長さに切断して電池素子としている。このため、正・負電池素子の原反部より捲回部巻芯までの搬送距離が長く、搬送中に蛇行し易い。また、正・負極の原反の巻き状態の性質によっても大きく影響を受け、電池素子の捲回品質の低下原因になっている。更に、巻き状態の比較的良好な原反を用いた場合であっても、原反の巻き始めと巻き終わりとでは蛇行し易く、電池素子の捲回品質の低下原因になっている。  In the winding device for obtaining the secondary battery element having such a configuration, the positive / negative battery element material (raw material) and the separator and other insulators wound up in a roll shape are intermittently and intermittently sent to the winding part. The battery element is wound by winding with a wound core, and the positive / negative battery element material and the insulator such as a separator are cut to a predetermined length. For this reason, the conveyance distance from the raw fabric part of a positive / negative battery element to the winding part winding core is long, and it is easy to meander during conveyance. In addition, it is greatly affected by the nature of the positive and negative rolls, which causes a reduction in the winding quality of the battery element. Further, even when a raw material having a relatively good winding state is used, it is easy to meander at the beginning and end of winding of the raw material, which causes a reduction in the winding quality of the battery element.

そこで、特開平５−７４４４６号公報に開示されているように、電池コイル材料（正・負極電池素子材料）の幅方向の位置を検出する位置検出センサーと、巻き取られる電池コイル材料を案内しかつ回転軸の角度を調整可能な少なくとも一本の角度ロールとを有した巻取装置が知られている。  Therefore, as disclosed in Japanese Patent Laid-Open No. 5-74446, a position detection sensor for detecting the position in the width direction of the battery coil material (positive / negative battery element material) and the battery coil material to be wound are guided. A winding device having at least one angle roll capable of adjusting the angle of the rotation shaft is known.

また、特開平９−１２９２６０号公報に開示されているように、それぞれ送り出し軸に巻かれている正極および負極の集電体（正・負極電池素子材料）を巻き取り位置に送り出し、前記正極および負極の集電体をセパレーターを介装して巻回する電池用巻回機に装着され、少なくとも一方の集電体の幅方向の位置を調整するための集電体エッジ位置調整装置であって、前記集電体の幅方向の位置を検出するエッジ検出手段と、前記集電体を前記送り出し軸から送り出すために該送り出し軸を軸方向に進退させる軸移動手段と、前記送り出し軸から送り出された前記集電体を前記巻き取り位置に向かって案内するとともに、前記移動手段の作用下に該送り出し軸と一体的に前記軸方向に移動するパスローラーとを備えることを特徴とする電池用巻回機の集電体エッジ位置調整装置が知られている。  Further, as disclosed in JP-A-9-129260, positive and negative electrode current collectors (positive and negative battery element materials) wound around a delivery shaft are sent to a winding position, respectively, A current collector edge position adjusting device mounted on a battery winding machine for winding a negative electrode current collector with a separator interposed therebetween, and for adjusting a position in a width direction of at least one current collector. Edge detecting means for detecting a position in the width direction of the current collector, shaft moving means for moving the feed shaft forward and backward in order to feed the current collector from the feed shaft, and feed from the feed shaft And a path roller that guides the current collector toward the winding position and moves in the axial direction integrally with the feed shaft under the action of the moving means. Collector edge position adjusting apparatus times machines are known.

発明が解決しようとする課題Problems to be solved by the invention

しかしながら、前記特開平５−７４４４６号公報に開示されている従来技術では、回転軸の角度を調整可能な角度可変ロールを備えるため、装置全体の構成が相当に複雑化するとともに、この角度可変ロールを所望の角度に調節するための制御が複雑なものになるという問題が指摘される。  However, the prior art disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 5-74446 includes an angle variable roll that can adjust the angle of the rotating shaft. It is pointed out that the control for adjusting the angle to a desired angle becomes complicated.

また、前記特開平９−１２９２６０号公報に開示されている従来技術では、原反巻き出し軸直後では蛇行補正が可能であっても、原反部より捲回巻芯までの搬送距離が長い場合では、搬送途中の蛇行補正を行うことが不可能であるという問題が指摘される。  In the prior art disclosed in Japanese Patent Laid-Open No. 9-129260, even if the meandering correction is possible immediately after the original unwinding shaft, the conveyance distance from the original fabric portion to the wound core is long. Then, the problem that it is impossible to perform meandering correction in the middle of conveyance is pointed out.

本発明はこれらの問題を解決するものであり、簡単な構成で電池素子材料の幅方向の蛇行補正を高精度でかつ迅速に遂行可能な電池素子捲回用蛇行補正装置を提供することを目的とする。  The present invention solves these problems, and an object of the present invention is to provide a meandering correction device for winding a battery element that can perform a meandering correction in the width direction of the battery element material with high accuracy and quickly with a simple configuration. And

課題を解決するための手段Means for solving the problem

前記の課題を解決するために、本発明では電池素子材料の幅方向の蛇行を検出するためのセンサーと、捲回される電池素子材料を案内しかつ幅方向に進退しながら蛇行を補正する少なくとも一本以上の移動ローラーを有し、前記蛇行検出センサーにより電池素子材料の幅方向の蛇行が検出されると、この蛇行を補正する方向に移動ローラーが幅方向に進退するものである。  In order to solve the above problems, the present invention provides a sensor for detecting the meandering of the battery element material in the width direction, and at least corrects meandering while guiding the wound battery element material and moving back and forth in the width direction. When the meandering detection sensor detects meandering in the width direction of the battery element material, the moving roller advances and retreats in the width direction in a direction to correct the meandering.

蛇行検出センサーは電池素子として捲回される電池素子材料が搬送途中で電池素子の巻きずれの原因となる幅方向への蛇行を生じた場合これを検出するものである。移動ローラーは幅方向への進退により搬送途中の電池素子材料の蛇行を補正するものであり、蛇行検出センサーの蛇行検出に基づいて作動するものである。  The meandering detection sensor detects when a battery element material wound as a battery element causes a meandering in the width direction that causes a winding deviation of the battery element during conveyance. The moving roller corrects the meandering of the battery element material being conveyed by advancing and retreating in the width direction, and operates based on the meandering detection of the meandering detection sensor.

本発明の実施の形態を図面により具体的に説明する。図１は本発明の実施の形態に係る電池素子巻回装置用蛇行補正装置の概略構成図である。図１に示すように、電池素子巻回装置用蛇行補正装置は電池素子材料１の蛇行を検出する蛇行検出センサー２と該蛇行検出センサー２からの信号に基づいて回転するモーター１１を有し、原反より送り出され、捲回部巻芯によって捲回される搬送途中の電池素子材料１が蛇行し始めると、蛇行検査センサー２によって蛇行が検出される。蛇行検査センサー２からの信号により、モーター１１が回転し、モーター１１と自在継手１０によって連結させたボールねじ９が回転すると、スライドガイド８を介したスライドローラーガイド７に固定させた移動ローラー６を有する軸１３はボールブッシュ１２を介して、ＢまたはＣ方向へ移動する。  Embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 is a schematic configuration diagram of a meandering correction device for a battery element winding device according to an embodiment of the present invention. As shown in FIG. 1, the meandering correction device for a battery element winding device has a meandering detection sensor 2 that detects meandering of the battery element material 1 and a motor 11 that rotates based on a signal from the meandering detection sensor 2. When the battery element material 1 that is being fed out from the raw material and is being wound around the winding core starts to meander, the meandering sensor 2 detects meandering. When the motor 11 is rotated by the signal from the meandering inspection sensor 2 and the ball screw 9 connected by the motor 11 and the universal joint 10 is rotated, the moving roller 6 fixed to the slide roller guide 7 via the slide guide 8 is moved. The shaft 13 is moved in the B or C direction via the ball bush 12.

また、電池素子材料１の捲回・搬送中では押えローラー５は軸１４とボールブッシュ３を介してエーアシリンダ４によりＤ方向へ移動され、移動ローラー６とによって電池素子材料１を挟み込み押さえつけることが可能である。更に、押えローラー５は軸１４とボールブッシュ３を介してスライドローラーガイド７に固定されているため、移動ローラー６と同期して矢印Ｂ方向または矢印Ｃ方向への移動が可能である。  Further, during the winding and transporting of the battery element material 1, the presser roller 5 is moved in the direction D by the air cylinder 4 through the shaft 14 and the ball bush 3, and the battery element material 1 can be sandwiched and pressed by the moving roller 6. Is possible. Further, since the presser roller 5 is fixed to the slide roller guide 7 via the shaft 14 and the ball bush 3, the presser roller 5 can be moved in the arrow B direction or the arrow C direction in synchronization with the moving roller 6.

図２は本発明の実施の形態に係る電池素子捲回装置用蛇行補正装置の側面の様子を示したものである。スライドローラーガイド７にはセンサー検出羽１６を有し、該センサー検出羽１６は矢印Ｂ方向または矢印Ｃ方向へ共に移動する。また、フレーム１５には手前側オーバートラベルセンサー１７と奥側オーバートラベルセンサー１８と手前側原点センサー１９および奥側原点センサー２０が設けられていて、モーター１１の回転に伴うスライドガイド８を介したスライドローラーガイド７の移動量を制御している。手前側原点センサーおよび奧側原点センサーは検出羽１６によって原点の位置を検出している。また、万が一手前側オーバートラベルセンサー１７および奥側オーバートラベルセンサー１８が検出羽１６を検出した場合、モーターは瞬時に停止して、オーバーラン等による装置の破損を防止している。  FIG. 2 shows a side view of the meandering correction device for a battery element winding device according to the embodiment of the present invention. The slide roller guide 7 has sensor detection wings 16 that move together in the direction of arrow B or arrow C. The frame 15 is provided with a front side overtravel sensor 17, a back side overtravel sensor 18, a front side origin sensor 19, and a back side origin sensor 20, and is slid through a slide guide 8 as the motor 11 rotates. The amount of movement of the roller guide 7 is controlled. The front-side origin sensor and the heel-side origin sensor detect the position of the origin by the detection blade 16. In the unlikely event that the front side overtravel sensor 17 and the back side overtravel sensor 18 detect the detection wing 16, the motor stops instantaneously to prevent damage to the device due to overrun or the like.

図３は本発明の実施形態に係る電池素子捲回装置用蛇行補正装置の正面より断面の様子を示す図である。移動ローラー６を有する軸１３に対し、電池素子材料搬送方向矢印Ａとは反対方向に固定ローラー２３とガイド付きエアーシリンダ２１によって矢印ＦまたはＧ方向へ移動可能な押さえクランパ２２が設けられている。ガイド付きエアーシリンダ２１によって矢印Ｇ方向へ押えクランパ２２と固定ローラー２３とが電池素子材料１を挟み込み押え付け、更にエアーシリンダ４によって押えローラー５を矢印Ｅ方向へ移動することにより移動ローラー６と電池素子材料１が開放され、電池素子材料１を幅方向へ移動させることなく押えローラー５および移動ローラー６を幅方向へ移動させることが可能である。  FIG. 3 is a diagram showing a cross-sectional view from the front of the meandering correction device for a battery element winding device according to the embodiment of the present invention. A pressing clamper 22 that is movable in the direction of arrow F or G by a fixed roller 23 and a guided air cylinder 21 is provided on the shaft 13 having the moving roller 6 in a direction opposite to the battery element material conveyance direction arrow A. The holding clamper 22 and the fixed roller 23 sandwich and press the battery element material 1 in the direction of arrow G by the air cylinder 21 with guide, and further move the pressing roller 5 in the direction of arrow E by the air cylinder 4 to move the moving roller 6 and the battery. The element material 1 is opened, and the pressing roller 5 and the moving roller 6 can be moved in the width direction without moving the battery element material 1 in the width direction.

このように構成される電池素子捲回装置用蛇行補正装置の作動について図面により具体的に説明する。原反より送り出される図１中の電池素子材料１が捲回部巻芯によって捲回されると矢印Ａ方向へ搬送される。搬送途中の電池素子材料１が蛇行し始まると、蛇行検出センサー２によって蛇行が検出される。該蛇行検出センサーが蛇行を検出すると、モーター１１へ駆動信号を送信する。  The operation of the meandering correction device for a battery element winding device configured as described above will be specifically described with reference to the drawings. When the battery element material 1 in FIG. 1 sent out from the original fabric is wound by the winding portion core, it is conveyed in the direction of arrow A. When the battery element material 1 in the middle of conveyance starts to meander, the meandering detection sensor 2 detects meandering. When the meander detection sensor detects meandering, a drive signal is transmitted to the motor 11.

この駆動信号によってモーター１１が回転し、そのモーター１１と自在継手１０によって連結されているボールねじ９が回転し、ボールねじ９の作用によりスライドガイド８上に矢印Ｃまたは矢印Ｄ方向に摺動自在に介されたスライドローラーガイド７が矢印Ｃまたは矢印Ｄ方向へ移動する。スライドローラーガイド７には移動ローラー６を設ける軸１３がフレーム１５にと固定されているボールブシュ１２を介して固定しており、移動ローラー６も容易にモーター１１の作動により矢印Ｃまたは矢印Ｄ方向へ移動する。    The motor 11 is rotated by this drive signal, the ball screw 9 connected to the motor 11 by the universal joint 10 is rotated, and the ball screw 9 can be slid on the slide guide 8 in the direction of arrow C or arrow D. The slide roller guide 7 is moved in the direction of arrow C or arrow D. A shaft 13 provided with a moving roller 6 is fixed to the slide roller guide 7 via a ball bush 12 fixed to a frame 15. The moving roller 6 can be easily operated in the direction of arrow C or arrow D by the operation of the motor 11. Move to.

また、押えローラー５もスライドローラーガイド７に固定されており、移動ローラー６と同期する作動となり、電池素子材料１を常に挟み込み押えながら矢印Ｃまたは矢印Ｄ方向へ移動する。これにより、電池素子材料１の幅方向の蛇行が迅速かつ正確に補正されるという効果が得られる。そして、蛇行補正センサーが電池素子材料１の蛇行を検出しなくなるまで移動ローラー６とその同期する押えローラー５は矢印Ｃまたは矢印Ｄ方向へ移動し続ける。  The presser roller 5 is also fixed to the slide roller guide 7 and operates in synchronization with the moving roller 6, and moves in the direction of arrow C or arrow D while always pinching and holding the battery element material 1. Thereby, the effect that the meander of the width direction of the battery element material 1 is correct | amended rapidly and correctly is acquired. The moving roller 6 and the presser roller 5 that synchronizes with the moving roller 6 continue to move in the direction of the arrow C or the arrow D until the meandering correction sensor no longer detects the meandering of the battery element material 1.

しかし、電池素子材料１の蛇行量が大きく図２中の手前側原点検出センサー１９または奥側原点検出センサー２０からスライドローラーガイド７に固定された検出羽１６が外れると想定移動量オーバーとなり原点復帰動作に移行する。  However, if the detecting element 16 fixed to the slide roller guide 7 is removed from the near-side origin detection sensor 19 or the back-side origin detection sensor 20 in FIG. Move to operation.

図３において押えクランパ２２がガイド付きエアーシリンダ２１によって矢印Ｆ方向へ移動し固定ローラー２３とで電池素子材料１を挟み込み押さえつける。押えローラー５はエアーシリンダ４によって矢印Ｅ方向へ移動し電池素子材料１を開放する。ここに図２では矢印Ｂまたは矢印Ｃ方向へ移動し、手前側原点検出センサー１９および奥側原点検出センサー２０がともに検出する位置で停止する。更に図３においてエアーシリンダ４によって矢印Ｄ方向へ移動し移動ローラー６との間に電池素子材料１を挟み込み押え付け、ガイド付きエアーシリンダ２１によって矢印Ｇ方向へ移動し固定ローラー２３との間の電池素子材料１を開放する。以上が原点復帰動作である。但し、原点復帰動作は電池素子材料の捲回が優先であるため、一サイクル終了後と次のサイクル開始前に行われる。    In FIG. 3, the presser clamper 22 is moved in the direction of arrow F by the air cylinder 21 with guide, and the battery element material 1 is sandwiched and pressed by the fixed roller 23. The presser roller 5 is moved in the direction of arrow E by the air cylinder 4 to release the battery element material 1. Here, in FIG. 2, it moves in the direction of arrow B or arrow C, and stops at a position where both the front-side origin detection sensor 19 and the back-side origin detection sensor 20 detect. Further, in FIG. 3, the battery element material 1 is sandwiched and pressed between the moving roller 6 by moving with the air cylinder 4 in FIG. 3, and is moved in the direction of arrow G with the air cylinder 21 with guide to the battery between the fixed roller 23. The element material 1 is opened. The above is the origin return operation. However, the return to origin operation is performed after the end of one cycle and before the start of the next cycle because the battery element material is prioritized.

発明の効果The invention's effect

本発明は以上説明した通りであり、電池素子材料１の幅方向の蛇行が迅速かつ正確に補正されるという効果が得られる。また、移動ローラーおよび押えローラーが軸方向に進退するだけであり、構成が有効に簡素化されるとともに、その制御が容易に行われる。  The present invention is as described above, and the effect that the meandering of the battery element material 1 in the width direction is corrected quickly and accurately is obtained. Further, the moving roller and the pressing roller only advance and retreat in the axial direction, and the configuration is effectively simplified and the control is easily performed.
