【発明の属する技術分野】
この発明は、靴下編み立て機でつま先まで編み上がった靴下生地を、靴下編み立て機から自動的に取り出してつま先部分を自動的に縫い合わせるために用いる靴下のつま先縫製用の靴下移し針に関する。
【０００２】
【従来の技術】
一般的な靴下の製造は、丸編機や靴下編機の如き靴下編み立て機を用い、靴下の口ゴム部、身ごろ、踵、足部、つま先までを編み上げる靴下生地の編み上げ工程と、開口するつま先部分を先かがりする工程とを経て行われる。
【０００３】
従来、つま先部分を先かがりする工程は、靴下編み立て機から編み上がった靴下生地を取り外し、この靴下生地を裏返しにした状態で別途用意した先かがり機につま先部分をセットし、このつま先部分を手作業でかかることにより縫い合わせるようにしていた。
【０００４】
【発明が解決しようとする課題】
上記のような、従来のつま先処理方法は、靴下編み立て機からの靴下生地の取り外し、先かがり部分への靴下生地の移送、靴下の裏返し、先かがり機への靴下生地のセット、つま先部分の縫い合わせ等の全てが、作業者による手作業によって行わなければならないため、靴下の製造能率を低下させ、製品の製造コストを高騰させる大きな要因になっている。
【０００５】
そこで、この発明の課題は、靴下編み立て機でつま先まで編み上がった靴下生地を、靴下編み立て機から自動的に取り出してつま先部分を自動的に縫い合わせることができ、靴下の製造効率の向上と省力化により、製造コストの低減が図れる靴下のつま先縫製用の靴下移し針を提供することにある。
【０００６】
【課題を解決するための手段】
上記のような課題を解決するため、この発明は、カム部材との結合杆と針先形成杆を直角に連成し、針先形成杆の先端に設けた針先が、対向させた幅の狭い二枚の金属板を相反する外側に屈曲させることによって対向面間に上下に長い貫通孔を形成し、一方金属板の先端を他方金属板の側面に臨ませ、両金属板の貫通孔を形成した部分の途中で内側縁に凹欠部を設けて形成されている構成を採用したものである。
【０００７】
この発明における上記針先は、貫通孔を形成した部分の途中が外側に屈曲し、上記凹欠部が外側に屈曲した部分の根元に設けられ、他方金属板の先端部側縁に傾斜側壁を設けるようにしてもよく、さらに、他方金属板の先端部内側面に、一方金属板の先端が納まる凹溝を設けることができる。
【０００８】
【発明の実施の形態】
以下、この発明の実施の形態を図示例と共に説明する。
【０００９】
図４乃至図８に示すように、この発明の靴下のつま先縫製用の靴下移し針を使用する靴下のつま先縫製装置は、丸編機や靴下編機の如き靴下生地を編み上げる靴下編み立て機１と、複数の移し針移動台２が円形の配置と両側に向かい合わせとなる直線状の配列に集合離反自在となり、上記靴下編み立て機１の直上での上下動と、靴下編み立て機１の直上に対する水平方向の進退動が自在となるように配置され、靴下編み立て機１で編み上がった靴下生地Ａを自動的に移し取ると共に、移し取った靴下生地Ａを水平方向に移送する靴下移し装置３と、この靴下移し装置３の水平方向への移動途中に配置され、靴下移し装置３で移送される靴下生地Ａのつま先部分を縫い合わせるミシンとで構成されている。
【００１０】
上記靴下編み立て機１は、回転する円筒状のシリンダ（以下釜４という）と、この釜４の外周面に設けた溝で上下動可能に保持され、靴下生地Ａを形成する多数の編み針５と、釜４のシンカーベットに組み込まれ、編み針５とで網み目を形成するシンカー６と、上記釜４の内側に配置され、網み目をシンカー６の爪から外すと共に、編み針５にかかっているループを後述する移し針に移動させる移しビット７と、釜４の内部に配置され、靴下生地Ａをバキュームで吸引して引き下げる生地下げ用のバキュームパイプ８とを有し、釜４の回転と図示省略したカムによる編み針５の上下動により、靴下生地Ａとなる口ゴム部、身ごろ、踵、足部、つま先までを編み上げるようになっている。
【００１１】
前記靴下移し装置３は、固定台９上の靴下編み立て機１から離れた位置に支柱１０を立設し、この支柱１０に水平のベースプレート１１を、該支柱１０を中心とする回転と上下動が自在となるよう取り付け、ベースプレート１１の上下動は固定台９との間に設けたシリンダ１２で行うと共に、このベースプレート１１が靴下編み立て機１の上部で停止する状態で、ベースプレート１１の上面で靴下編み立て機１の直上の位置に、上下端が開放し、内径が釜４の外径に略一致する垂直の円筒部１３が該靴下編み立て機１と同軸心状となるよう設けられている。
【００１２】
上記円筒部１３の内部に、外周面に多数の溝１４が形成されたガイドリング１５が上下動自在に挿入され、その上端に固定した昇降プレート１６とベースプレート１１との間に設けたシリンダ１７によって該ガイドリング１５が上下動すると共に、このガイドリング１５の内部に、靴下編み立て機１で編み上がった靴下生地Ａを吸引して上方に引き上げるバキュームパイプ１８が上下動自在に挿入され、バキュームパイプ１８はガイドリング１５と同時に上下動すると共に、その上端に固定した昇降プレート１９とガイドリング１５の昇降プレート１６の間に設けたシリンダ２０によって、該バキュームパイプ１８に、独立した上下動を与えるようになっている。
【００１３】
上記ベースプレート１１の下面に、円状の配置状態で円筒部１３と同軸心状となり、円状の配置から円筒部１３の軸心状で、両側に向かい合わせとなる直線状の配列に集合離反自在となる複数の移し針移動台２が配置されている。
【００１４】
この移し針移動台２は、角形の上部ブロック２１と下部のホルダー２２とで形成され、ホルダー２２に円状の配置状態で半径方向に沿う複数の溝２３が設けられ、各溝２３内に、この発明の移し針２４とカム部材２５が移動可能に保持され、カム部材２５を介してシリンダ２６で各移し針２４が同時に移動を付与されるようになっている。
【００１５】
上記各移し針移動台２に設けた溝２３によって保持された移し針２４の全合計数は、靴下編み立て機１の編み針５と同数に設定され、また、前記ガイドリング１５の外周面に形成した溝１４の数も同数になっている。
【００１６】
図１と図２は、この発明の靴下移し針２４の第１の実施の形態を示し、図面は移し針２４の構造を理解し易くするために、針先を上にした状態で表示している。
【００１７】
この移し針２４は、二枚の金属板４１，４１ａを重ね合わせた構造を有し、カム部材２５との結合杆４２と針先形成杆４３を直角に連成してＬ字状に屈曲し、移し針移動台２の溝２３に嵌まるカム部材２５との結合杆４２には、途中に凸部４４が設けられ、この移し針２４を移動させるカム部材２５には、図１（Ａ）のように、移し針２４をガイドリング１５まで押し出して円形の配置にするカム２５ａと、移し針２４を移し針移動台２の内部にまで引き込んで直線にするカム２５ｂが、凸部４４を挟むようにして設けられ、各移し針移動台２の全移し針２４とカム部材２５は、各移し針移動台２毎に設けた一つのシリンダ２６によって同時に移動することになる。
【００１８】
上記針先形成杆４３の先端に設けた針先４５は、二枚の金属板４１、４１ａの対向させた幅の狭い部分を相反する外側に屈曲させることによって対向面間に上下に長い六角形の貫通孔４６を形成し、一方金属板４１の先端を他方金属板４１ａの側面に臨ませ、両金属板４１、４１ａの貫通孔４６を形成した部分の途中で内側縁に、靴下生地Ａの爪先のループａが係合する凹欠部４７を設けて形成されている。
【００１９】
上記針先４５の貫通孔４６を形成した部分の途中が図１（Ａ）のように外側に屈曲し、上記凹欠部４７が外側に屈曲した部分の根元に設けられ、一方金属板４１の先端部が先端に向けて細幅となると共に、他方金属板４１ａの先端部で両側縁に略三角形の傾斜側壁４８を設け、一方金属板４１の先端部が両傾斜側壁４８間に収まり、この一方金属板４１の先端部は金属板の弾性を利用し、他方金属板４１ａに対して先端が開くことのできる弾性を有している。
【００２０】
図３に示す第３の実施の形態の移し針２４における針先４５の構造は、他方金属板４１ａの先端部を先端に向けて細幅とし、この他方金属板４１ａの先端部内側面に、一方金属板４１の先端が離反可能に納まる凹溝４９を設けた構造になっている。
【００２１】
この発明の靴下のつま先縫製用の靴下移し針は、上記のような構成であり、次に、この靴下移し針２４の使用方法を説明する。
【００２２】
図４、図５のように、靴下編み立て機１による靴下生地Ａの編み上げが終了すると、靴下移し装置３は、上昇位置にある水平のベースプレート１１が支柱１０を中心に回転して靴下編み立て機１の直上に臨んで停止し、ベースプレート１１の下面に装着した複数の移し針移動台２は、靴下編み立て機の釜４と同軸心で円形の配置となり、各移し針移動台２で保持した移し針２４は、引き込まれて移し針移動台２の先端面から突出しないようになっていると共に、下向きに突出状となるその針先４５と靴下編み立て機１の編み針５の上端の間に上下の間隔が保たれている。
【００２３】
また、靴下編み立て機１は、靴下生地Ａの編み上げが終了すると、編み針５の高さを上昇させたクリヤー位置に揃え、釜４を定位置に止める。この状態で、靴下生地Ａはバキュームパイプ８のブロワーによる吸引で靴下編み立て機１内に引き下げられているので、靴下生地Ａのつま先部分のループａは、編み針５のフック５ａ内から外れてシンカー６の位置にまで下がり、次に、靴下移し装置３のベースプレート１１が、図６のようにシリンダ１２で移し位置にまで下がり、靴下編み立て機１の編み針５のフック５ａと、移し針移動台２で保持した移し針２４の針先４５を同じ水平高さの配置にし、ガイドリング１５とバキュームパイプ１８を下降位置に下げ、ガイドリング１５の下部を円形の配置となる移し針移動台２群の内部に進入させて移し針２４の高さに位置させる。
【００２４】
この状態で、各移し針移動台２のシリンダ２６を伸長作動させ、カム部材２５のカム２５ａを介して各移し針２４をガイドリング１５に向けて弧状の配置で押し出し、図７のように、その先端をガイドリング１５の溝１４にまで入れると、全移し針２４は釜４の軸心を中心とする円形の配置となり、その針先４５が靴下編み立て機１の編み針５の編み針５のフック５ａに対して嵌まり込むことになる。
【００２５】
次に、シリンダ２０の収縮でバキュームパイプ１８を、その下端開口がシンカー６に臨む高さまで下げ、この状態でバキュームパイプ１８のブロアーを作動させると、靴下編み立て機１の靴下生地Ａはバキュームパイプ１８内に吸い込まれ、この吸い上げにより靴下生地Ａは図８のように裏返しの状態となり、続いて、シリンダ２０の伸長でバキュームパイプ１８をガイドリング１５内に納まる位置にまで上げる。
【００２６】
靴下編み立て機１の移し針ビット７を、移し針２４に靴下生地Ａのループａが完全に入る高さにまで上昇させた後、この移し針ビット７を不作用の位置にまで後退させる。図１０（Ａ）と（Ｂ）は、靴下生地Ａのループａが靴下編み立て機１の編み針５から移し針２４の針先４５に移行する過程を示しており、移し針２４の針先４５が編み針５のフック５ａに対して嵌まり込んだ状態で、靴下生地Ａがバキュームパイプ１８の吸引で裏返しとなって引き上げられると、ループａは編み針５から移し針２４の針先４５へと円滑に移行することになり、ループａが移し針２４へ移行することにより、このループａが針先４５の凹欠部４７に係合して保持され、靴下生地Ａは靴下編み立て機１から靴下移し装置３に裏返し状態で移ることになる。
【００２７】
次に、シリンダ２６の収縮で各移し針２４を外方に直線状の配列状態で逃がし、針先４５を編み針５のフック５ａから離脱させることにより、針先４５でループａが保持された靴下生地Ａのつま先は円形に拡径され、この後、バキュームパイプ１８と共に、ガイドリング１５を不作用位置に上昇させ、続いてシリンダ１０の伸長でベースプレート１１を下降した移し位置から上昇位置に戻し、この状態で全移し針移動台２を釜４の軸心に向けて集合移動させると、図９のように、全移し針移動台２は円形の配置から直線の配置に移行し、全移し針移動台２は両側に向かい合わせとなる直線状の配列となることにより、靴下生地Ａのつま先部分の途中を移し針移動台２の先端面で両側から互いに挟み込んで偏平な状態とし、つま先の先端が移し針移動台２の下面と移し針２４の針先４５の間に突出している。
【００２８】
このように、移し針移動台２群が直線の配置になって靴下生地Ａのつま先部分を挟み込むと、靴下移し装置３は、ベースプレート１１が支柱１０を中心に回動して靴下編み立て機１の上から離反し、この移動により、靴下生地Ａの移し針移動台２で挟み込まれたつま先部分がミシンの上部に送られ、移し針移動台２の下面と移し針２４の針先４５の間に突出しているつま先の先端全長がこのミシンによって自動的にかがり縫いされる。
【００２９】
上記のように、ミシンによるつま先のかがり縫いが完了すると、バキュームパイプ１８のブロアーを止め、移し針移動台２を円形の配置に戻して靴下を引き下げて靴下移し装置３から外すことにより靴下製造工程の全てが完了すると共に、靴下編み立て機１はラッチリングを下ろし、靴下生地の編み上げを再開することになる。
【００３０】
【発明の効果】
以上のように、この発明によると、カム部材との結合間と針先形成間を直角に連成し、針先形成間の先端に設けた針先が、対向させた幅の狭い二枚の金属板を相反する外側に屈曲させることによって対向面間に上下に長い貫通孔を形成し、一方金属板の先端を他方金属板の側面に臨ませ、両金属板の貫通孔を形成した部分の途中で内側縁に凹欠部を設けたので、靴下編み立て機で編成した靴下生地がつま先まで編み上がると、靴下生地を上部から吸引して上昇させることで、靴下生地を裏返しにしてつま先開口部のループを編み針から靴下移し針の針先に移行させ、これによって、裏返しになった靴下生地を靴下編み立て機から移し針の針先に持ち替えて、つま先縫製位置のミシンでつま先部分を自動的に縫い合わせることができ、これにより、靴下編み立て機でつま先まで編み上がった靴下生地を、靴下編み立て機から自動的に取り出してつま先部分を自動的に縫い合わせることが可能になり、従って、靴下生地の編み上げからつま先の縫い合わせまでの全ての工程が自動的に行えることになり、靴下の製造効率の向上と省力化が可能になり、靴下の製造コストの低減が図れることになる。

In this state, the cylinder 26 of each transfer needle moving base 2 is operated to extend, and each transfer needle 24 is pushed out in an arcuate arrangement toward the guide ring 15 via the cam 25a of the cam member 25, as shown in FIG. When the tip is inserted into the groove 14 of the guide ring 15, the all-transfer needle 24 is arranged in a circular shape centering on the shaft center of the hook 4, and the needle tip 45 of the knitting needle 5 of the sock knitting machine 1. It fits into the hook 5a.
[0025]
Next, when the vacuum pipe 18 is lowered to the height at which the lower end opening faces the sinker 6 by contraction of the cylinder 20 and the blower of the vacuum pipe 18 is operated in this state, the sock fabric A of the sock knitting machine 1 becomes the vacuum pipe. The sock fabric A is turned upside down as shown in FIG. 8 by this suction, and then the vacuum pipe 18 is raised to a position in the guide ring 15 by extension of the cylinder 20.
[0026]
After the transfer needle bit 7 of the sock knitting machine 1 is raised to a height at which the loop a of the sock fabric A completely enters the transfer needle 24, the transfer needle bit 7 is retracted to the inoperative position. 10A and 10B show a process in which the loop a of the sock fabric A is transferred from the knitting needle 5 of the sock knitting machine 1 to the needle tip 45 of the transfer needle 24, and the needle tip 45 of the transfer needle 24 is shown. When the sock fabric A is turned upside down and pulled up by suction of the vacuum pipe 18 in a state in which is inserted into the hook 5a of the knitting needle 5, the loop a is moved from the knitting needle 5 to the needle tip 45 of the needle 24 smoothly. When the loop a shifts to the transfer needle 24, the loop a is engaged and held in the recess 47 of the needle tip 45, and the sock fabric A is transferred from the sock knitting machine 1 to the sock knitting machine 1. It moves to the transfer device 3 in an inverted state.
[0027]
Next, the socks in which the loop a is held by the needle tip 45 by releasing each of the transfer needles 24 in a linear arrangement outward by the contraction of the cylinder 26 and detaching the needle tip 45 from the hook 5 a of the knitting needle 5. The toe of the dough A is expanded in a circular shape, and thereafter, together with the vacuum pipe 18, the guide ring 15 is raised to the non-operating position, and then the base plate 11 is lowered by the extension of the cylinder 10 to return to the raised position. In this state, when the total moving needle moving base 2 is collectively moved toward the axis of the shuttle 4, as shown in FIG. 9, the total moving needle moving base 2 shifts from a circular arrangement to a linear arrangement, and the total moving needle is moved. The moving table 2 is arranged in a straight line so as to face both sides, so that the toe portion of the sock fabric A is moved halfway between the two sides of the tip of the needle moving table 2 so as to be in a flat state. Moved Protruding between the needle tip 45 of the needle 24 is transferred with the lower surface of the moving base 2.
[0028]
As described above, when the transfer needle moving base 2 group is arranged in a straight line and the toe portion of the sock fabric A is sandwiched, the sock transfer device 3 rotates the base plate 11 around the support column 10 so that the sock knitting machine 1 As a result of this movement, the toe portion sandwiched by the transfer needle moving table 2 of the sock fabric A is sent to the upper part of the sewing machine, and between the lower surface of the transfer needle moving table 2 and the needle tip 45 of the transfer needle 24. The total length of the tip of the toe that protrudes to the sewing machine is automatically overlocked by this sewing machine.
[0029]
As described above, when the sewing of the toe by the sewing machine is completed, the blower of the vacuum pipe 18 is stopped, the transfer needle moving base 2 is returned to the circular arrangement, the sock is lowered, and the sock transfer device 3 is detached from the sock manufacturing apparatus. When all of the above are completed, the sock knitting machine 1 lowers the latch ring and resumes knitting of the sock fabric.
