Description

【０００１】
【発明の属する技術分野】
本発明は、靴下編機で編成した爪先部が開いた靴下を裏返して機外に搬出する搬出方法および搬出装置に関する。
【０００２】
【従来の技術】
一般に、靴下編機により作られる靴下は、爪先部が開いた状態で編成され、次工程で爪先開口部をミシン等で縫製することで完成品とされる。
【０００３】
しかし、爪先部が開いた靴下をそのまま次工程においてミシン縫製すると、靴下は、爪先部を裏面が接した状態で縫製されるので、靴下の爪先部を縫製する縫い目線が靴下の表面に露出してしまうことになり、製品の外観を見苦しくしてしまう。
【０００４】
爪先部の縫い目線の露呈は、靴下を裏返して爪先部が表面で接するようにして縫製するがことで防ぐことはできるが、靴下編機から取り出した靴下を裏返し、裏返した靴下を縫製する作業を作業員の手作業で行うことは、作業が面倒であるとともに作業効率を上げることが難しい。
【０００５】
そこで、靴下編機により作られる靴下を靴下編機から取り出す前に裏返すようにした技術手段が開発された。
【０００６】
特公昭６１−３１２２５号公報には、爪先部が開いた靴下を靴下編機から取り出す前に裏返すために、ダイヤルハブと板体で編地のウエルト部を挟持し、２重の袋状に編成した後、糸を切断し、裏返しの状態で下方に吸引搬送するようにした靴下生地の表裏反転装置が記載されている。
【０００７】
特開平１−２４６４５０号公報には、外筒と内部要素を下方が大きい直径とし、内部要素を上部と下部に分割し、編み終わったら、上部を摺動部材で挟み、下部を下降し、下部の上縁開口部からエアにより反転して編地を搬出する円形編成機における編成物の緊張兼裏返し装置が記載されている。
【０００８】
特開平４−１５８８９１号公報には、シリンダと同期回転する捩じれ防止筒と、ダイヤルの下部に下方にエアを噴射する円錐ノズルを有し編成した編地を圧縮空気で下方に引き出すようにした編地引出し装置がが記載されている。
【０００９】
【発明が解決しようとする課題】
しかしながら、靴下編機から取り出す前に靴下を裏返す手段は、編成始め部分で保持して爪先部が開いた靴下を裏返すものであり、靴下の保持位置の精度も低く、裏返した靴下を次工程で爪先部を縫製するために自動的に送り込むことができない。
【００１０】
本発明は上記した点に鑑みてなされたもので、靴下の爪先側を正確に保持し、後工程へ自動的に搬送して爪先部を縫製するすることを可能にする靴下を裏返して機外に搬出する搬出方法および搬出装置を提供することを目的とする。
【００１１】
【課題を解決するための手段】
本発明の靴下を裏返して機外に搬出する搬出装置は、編針シリンダの内側に編針シリンダと同期回転および上下動するように設けられたピン保持部材と、このピン保持部材の上面に周方向に間隔を置いて突設され、靴下の捨て糸部を保持する少なくとも２本のピンと、上記各ピンが挿通される孔を拡径部に有し上記ピン保持部材の内側に上下動自在に配置された編地ガイドと、上記編針シリンダの上方に配置され、上記靴下の捨て糸部を把持する靴下保持部を有し、上記編地ガイドを上昇させた状態で上記靴下の捨て糸部を該編地ガイドで支持したまま上記捨て糸部をそれまで保持していた上記ピン保持部材のピンに換えて上記靴下保持部によって掴み換える動作を行う手段と、上記編地ガイドと編成された靴下との間に上下動自在に設けられる裏返し用パイプを有し、上記靴下保持部に上記捨て糸部が保持された靴下を上記裏返しパイプの上昇により裏返すための靴下裏返し手段と、
を有し、靴下の爪先側を正確に保持し、後工程へ自動的に搬送して爪先部を縫製することを可能にする。
【００１２】
本発明の靴下を裏返して機外に搬出する搬出方法は、靴下編機により爪先部が開口した靴下を編成する工程と、上記靴下の爪先開口端に続いて捨て糸部を編成する工程と、上記靴下の捨て糸部を、編針シリンダの編針から外し、上記編針シリンダの内側に該編針シリンダと同期回転および上下動するように設けられたピン保持部材の少なくとも２本のピンで位置決め保持する工程と、上記各ピンが挿通される孔を拡径部に有し上記ピン保持部材の内側に上下動自在に配置された編地ガイドを上昇させた状態で上記靴下の捨て糸部を該編地ガイドで支持したまま上記捨て糸部をそれまで保持していた上記ピン保持部材のピンに換えて別の靴下保持部によって掴み換えることにより、上記靴下を上記ピン保持部材のピンから外す工程と、上記靴下の上記捨て糸部を固定した状態で、上記編地ガイドと編成された靴下との間に上下動自在に設けられる裏返し用パイプを上昇させて裏返し、上記靴下保持部で捨て糸部を把持したまま上記爪先の反対側の靴下端部を把持手段で把持した状態で裏返した靴下を機外に搬出する工程と、からなり、靴下の爪先側を正確に保持し、後工程へ自動的に搬送して爪先部を縫製することを可能にする。
【００１３】
【発明の実施の形態】
以下本発明の実施の形態を図面を参照して説明する。
図１および図２において、符号１は靴下編機の編針シリンダを示し、この編針シリンダ１の外周面には、上下方向に延びる溝が列設されており、列設した溝には、上から順に、編針２、中間ジヤック３および編針セレクトジヤック４が配置されている。中間ジヤック３はカム装置５により上下動し、対応する編針２を作動位置または不作動位置に移動させる。
【００１４】
上記編針シリンダ１の上部には、編針シリンダ１を囲むようにシンカーベット６が設けられている。このシンカーベット６にはシンカー７が半径方向に摺動可能に設けられている。シンカー７はカム手段８によって作動する。
【００１５】
上記編針シリンダ１の上方には、ダイアル装置９および糸供給装置１０が配置されている。ダイアル装置９は、編針シリンダ１と同期回転するように設けられている。糸供給装置１０から供給される編成糸１１により爪先部１２ａが開口した靴下１２が編成される。
【００１６】
一方、上記靴下編機には、編成した靴下１２を裏返して機外に搬出するための搬出装置２０が配設されている。
【００１７】
上記搬出装置２０は、図１ないし図３に示すように、編針シリンダ１の内面に設けた上下方向に延びる溝２１にキ−手段２２を介して上下動かつ編針シリンダ１と同期回転するように配置されたピン保持部材２３と、このピン保持部材２３の上面に周方向に９０度の間隔を置いて突設された４本のピン２４と、ピン保持部材２３を上下運動させる作動手段２５とを有する。
【００１８】
上記ピン保持部材２３の内側には、図１および図３に示すように、編成された靴下１２を編針シリンダ１の内部を下方に案内する編地ガイド２６が配置されている。上記編地ガイド２６は、ピン保持部材２３と同心に配置された円筒部２７と、この円筒部２７の上端から半径方向外方に延びる環状部２８とを有する。環状部２８には、ピン保持部材２３の各ピン２４に対応してピン２４が挿通される孔２９と、各孔２９に隣接して外端開口の溝３０が形成されている。
【００１９】
図３で示す実施の形態では、環状部２８には、孔２９と１つの溝３０と、孔２９とその両側の２つの溝３０，３０とが交互に配置されているが、環状部２８の溝３０の数はすべて１つであっても、すべて２つであってよい。
【００２０】
上記編地ガイド２６の内側に編成された靴下１２を裏返すためのパイプ３１が配置されている。上記パイプ３１は、図１に示すように、全体形状が円筒形であり、編地ガイド２６と編成された靴下１２との間に上下動自在に配置されている。パイプ３１の上昇運動により、爪先部１２ａを固定した靴下１２が裏返される。
【００２１】
また、上記編針シリンダ１の上方に靴下保持手段３２が配置されている。この靴下保持手段３２は、４つの靴下保持部３３を備えている。靴下保持手段３２は、図示しない機外搬出手段に回動自在に支持されている。各靴下保持部３３は、ピン保持部材２３の各ピン２４に対応してピン保持部材２３を囲むように配置されている。
【００２２】
上記各靴下保持部３３は、図１に示すように、本体部３４と、先端部にピン３５を有する板体３６と、先端にフォーク部３７ａを有し板体３６の上方に重なるように配置された編地押え３７と、先端にフォーク部３８ａを有し編地押え３７の下面に取り付けられた編地外しプレート３８とを有する。編地押え３７は基端部を本体部３４に上下方向に揺動自在に枢着されている。編地外しプレート３８は基端部を編地押え３７の下面に形成された溝に装着され、圧縮ばね３９によりばね付勢されている。
【００２３】
上記靴下保持部３３は、編地ガイド２６の環状部２８に設けた溝３０に対応して、図４に示す突設した２つのピン３５を有する靴下保持部３３ａと、図５に示す突設した１つのピン３５，３５を有する靴下保持部３３ｂの２種類で構成されている。
【００２４】
上記靴下保持部３３ａは、図４に示すように、２つのエアシリンダ５０，５１により作動する構造であり、エアシリンダ５０により板体３６と編地外しプレート３８と編地押え３７を半径方向内方に移動し、編地ガイド２６に支持された靴下１２の爪先開口端を編地外しプレート３８と編地押え３７の間に挿入し、エアシリンダ５１により編地外しプレート３８と編地押え３７を板体３６側に揺動し、編地ガイド２６に支持された靴下１２の爪先開口端を板体３６のピン３５と共働して保持し、板体３６と反対側に揺動して編地外しプレート３８により編地ガイド２６に支持された靴下１２を板体３６のピン３５から外すように作用する。
【００２５】
上記靴下保持部３３ｂは、図５に示すように、３つのエアシリンダ５０，５１，５２により作動する構造であり、エアシリンダ５０により板体３６と編地外しプレート３８と編地押え３７を半径方向内方に移動し、編地ガイド２６に支持された靴下１２の爪先開口端を編地外しプレート３８と編地押え３７の間に挿入し、エアシリンダ５１により編地外しプレート３８と編地押え３７を板体３６側に揺動し、編地ガイド２６に支持された靴下１２の爪先開口端を板体３６のピン３５と共働して保持し、板体３６と反対側に揺動して編地外しプレート３８により編地ガイド２６に支持された靴下１２を板体３６のピン３５から外し、エアシリンダ５２により板体３６と編地外しプレート３８と編地押え３７を対向位置の靴下保持部３３ｂの板体３６と編地外しプレート３８と編地押え３７半径方向と接する程度まで半径方向内方に移動させるように作用する。
【００２６】
さらに、上記編針シリンダ１の直上でかつパイプ３１の上昇途中位置に待機するように、裏返された靴下１２のゴム部１２ｂを把持する靴下把持手段４０が配置されている。靴下把持手段４０は、前記機外搬出手段に上下動自在に取り付けられている。
【００２７】
上記靴下把持手段４０は、図６に示すように、上端を軸４１に開閉自在に枢着された一対の掴み部４２，４２と、一対の掴み部４２，４２を開閉するように作動させるエアシリンダ装置（図示せず）とを有する。靴下把持手段４０は、靴下保持手段３２に爪先部１２ａを保持され裏返し用パイプ３１により裏返された靴下１２のゴム部１２ａを把持する。この場合、裏返し用パイプ３１の上端部に一対の掴み部４２，４２を通す程度の切欠きを設けておくことが好ましい。
【００２８】
また、靴下編機の外方には、靴下保持手段３２に保持された靴下１２を次の工程に配置された図示しないミシンに送り込むための靴下案内手段４３が配置されている、この靴下案内手段４３は、図７に示すように、靴下１２の重ね合わせた爪先部１２ｂ、好ましくは、ロッソコース部４４が通る程度の間隔を置いて配置された一対の案内部材を有する。
【００２９】
つぎに作用を説明する。
まず、靴下編機を運転して、糸供給装置１０から供給される編糸１１により、ゴム部１２ｂ、本体部１２ｃおよび爪先部１２ａの順に靴下１２を編成する。靴下１２は、爪先部１２ａの端部が開口している。さらに、靴下編機を運転を続けて、靴下１２の爪先部１２ａの開口端に続いてロッソコース部４４および捨て糸部４５を編成する。ロッソコース部４４および捨て糸部４５は、爪先部１２ａの開口端をミシンにより縫合する前の段階で切断される。
【００３０】
つぎに、編針シリンダ１内のピン保持部材２３を、キ−手段２２を介して編針シリンダー１に沿って上昇させると、ピン保持部材２３の上昇により、図８に示すように、ピン保持部材２３に設けたピン２４が編地ガイド２６の環状部２８に設けた孔２９を通して靴下１２の捨て糸部４５のルーブに突き刺さる。
【００３１】
ついで、ピン保持部材２３のピン２４を靴下１２の捨て糸部４５に突き刺した段階で、編針シリンダ１を回転させると、ピン保持部材２３と編針シリンダ１は同期回転するので、ピン保持部材２３は、ピン２４を靴下１２の捨て糸部４５に突き刺したまま編針シリンダ１とともに回転する。
【００３２】
これに続いて、編針シリンダ１の編針２を上昇および下降させると、編針シリンダ１の編針２が靴下１２の捨て糸部４５のループから外れ、靴下１２の捨て糸部４５のループは、ピン保持部材２３に設けたピン２４に移される。ピン保持部材２３に設けたピン２４は、周方向に９０度間隔で配置されているので、靴下１２の捨て糸部４５を等間隔の４ケ所で保持する。
【００３３】
つぎに、糸供給装置１０およびダイヤル装置９を、図９に示すように、待避位置に移動させ、ピン保持部材２３と編地ガイド２６を同時に所定位置まで上昇させる。
【００３４】
つぎに、編針シリンダ１の外周に待機させた靴下保持手段３２の各靴下保持部３３ａ，３３ｂを、図１０に示すように、編針シリンダ１の中心方向に移動させる。ピン保持部材２３に保持され、編地ガイド２６に支持された靴下１２の捨て糸部４５端は、靴下保持部３３ａ，３３ｂの編地外しプレート３８と編地押え３７の間に挿入され、板体３６に設けたピン３５が編地外しプレート３８の溝３０に挿入される。
【００３５】
ついで、靴下保持手段３２の各靴下保持部３３ａ，３３ｂを上昇させると、各靴下保持部３３ａ，３３ｂに設けたピン３５が編地ガイド２６に保持された靴下１２の捨て糸部４５のループに突き刺さる。これに続いて、編地外しプレート３８と編地押え３７を揺動して、編地ガイド２６に支持された靴下１２の捨て糸部４５を保持する。このように、靴下１２の捨て糸部４５を押さえることで靴下１２の捨て糸部４５の浮き上がりが防止される。
【００３６】
つぎに、ピン保持部材２３を、図１１に示すように下降させる、靴下保持部３３ａ，３３ｂを編針シリンダ１の半径方向外方へ移動させる。
【００３７】
つぎに、編地ガイド２６を、図１２に示すように下降させ、裏返し用パイプ３１を上昇させる。裏返し用パイプ３１の上昇により、靴下保持部３３に捨て糸部４５が保持された靴下１２は捨て糸部４５を基点として裏返される。
【００３８】
裏返された靴下１２は、図１３に示すように、編針シリンダ１の直上に待機された靴下把持手段４０の一対の掴み部４２，４２にゴム部１２ａが把持される。裏返された靴下１２が、靴下把持手段４０に把持されたら、裏返し用パイプ３１を下降させる。これにより、靴下１２の掴み換えが完了する。
【００３９】
つぎに、靴下保持手段３２の左右の靴下保持部３３ａ，３３ａを互いに離れる方向に作動させ、前後の靴下保持部３３ｂ，３３ｂを互いに近付きかつ接する方向に前進させる。これにより、裏返された靴下１２は、偏平となって中央部で合わせられる。
【００４０】
中央部を合わせて偏平となった靴下１２は、隣接して配置された靴下案内手段４３方向に搬送され、靴下１２のロッソコース部４４が靴下案内手段４３の一対の案内部材の間に差し込まれる。これにより、靴下１２は、裏返された爪先部分を位置合わせした状態で機外へ搬出され、後工程の爪先の縫製用ミシンに受け渡される。
【００４１】
【発明の効果】
以上述べたように、本発明によれば、靴下の裏返した爪先側を正確に保持し、後工程へ自動的に搬送して爪先部を縫製することが可能になる。
