Abstract
Description
本願は、2021年6月30日に日本に出願された特願2021-108562号に基づき優先権を主張し、その内容をここに援用する。
図1は、本実施形態の収容ユニット1の説明図である。図1には、収容ユニット1から線材10が引き出される様子が示されている。図2Aは、本実施形態の巻回体20の説明図である。図2Bは、本実施形態の巻回体20の断面説明図である。図3は、本実施形態の巻回体20の積層構造の説明図である。
また、以下の説明では、略円筒状の巻回体20の半径方向を「径方向」とする。径方向において巻回体20の中心との距離が遠くなる側を「プラス側」とする。
周回部21は、線材10を周方向に周回させて巻き回した部位である。周回部21には、時計回りに巻き回された線材10と、反時計回りに巻き回された線材10とが含まれる。周回部21は、後述するように、第1渦巻き部311、第2渦巻き部312、第3渦巻き部321及び第4渦巻き部322によって構成されている(図4参照)。なお、図中の周回部21は略円筒状であるが、周回部21が丸みを帯びた四角筒状になるように線材10が巻き回されても良い。
反転部22は、巻回方向を反転させて線材10を巻き回した部位である。反転部22は、後述するように、S字状又は逆S字状(Z字状)に線材10を巻き回した第1反転部313及び第2反転部323によって構成されている(図4参照)。
これに対し、本実施形態では、第1渦巻き部311及び第2渦巻き部312において、線材10が複数周(ここでは約4周)にわたって渦巻き状に巻き回されている。これにより、本実施形態では、図8に示す比較例と比べて、Z方向に垂直な方向に多くの線材10を収容可能になり、線材10の収容効率を高めることができる。
第1渦巻き部311を構成する線材10は、第1方向に外側から内側に向かって渦巻き状に巻き回されているため、第1渦巻き部311によって形成された空間Sは、第1方向に沿って外側から内側に向かう渦巻き状の空間となる。このため、第2方向に沿って空間Sをみた場合には、第1渦巻き部311によって形成された空間Sは、第2方向に内側から外側に向かう渦巻き状の空間となる。このため、本実施形態では、第1渦巻き部311によって形成された渦巻き状の空間Sに沿うように、第2渦巻き部312を構成する線材10を配置することが可能である。第2渦巻き部312の線材10が、第1渦巻き部311によって形成された空間Sに沿って配置されることによって、図2Bに示すように、本実施形態では、第1層31において、第1渦巻き部311を構成する線材10(図中のマイナス符号の線材10)と、第2渦巻き部312を構成する線材10(図中のプラス符号の線材10)と、が径方向に互い違いに配置されることになる。また、第1渦巻き部311を構成する線材10の間に、第2渦巻き部312を構成する線材10を配置させるため、第1渦巻き部311の線材10の周回数と、第2渦巻き部312の線材10の周回数とが同じであることが望ましい。
第1反転保持部423Aは、第1反転部313を構成する線材10の第1方向に巻き回された部位(線材10)と、第2方向に巻き回された部位(線材10)とをそれぞれ保持する。これにより、第1反転保持部423Aは、第1反転部313を構成する線材10を逆S字状(又はS字状)に保持することができる。
第2反転保持部423Bは、第2反転部323を構成する線材10の第2方向に巻き回された部位(線材10)と、第1方向に巻き回された部位(線材10)とをそれぞれ保持する。これにより、第2反転保持部423Bは、第2反転部323を構成する線材10をS字状(又は逆S字状)に保持することができる。
上述の実施形態は、本発明の理解を容易にするためのものであり、本発明を限定して解釈するためのものではない。本発明は、その趣旨を逸脱することなく、変更・改良され得ると共に、本発明には、その等価物が含まれることは言うまでもない。
