Description

【０００１】
【発明の属する技術分野】
この発明は、靴下の裏返し装置に関するものである。
【０００２】
【従来の技術】
一般に、靴下は筒状に編成されたのちに、裏向きに裏返されて爪先部を縫合され、こののち、再び表向きに裏返されて製品とされている。
【０００３】
まず、筒状の靴下生地を裏向きに裏返す装置としては、例えば、特開平４−２６３６６４号公報に記載されたものがある。この靴下の裏返し装置は、円型靴下編機の釜内部に、上端開口の２重吸引筒を配置して、内筒が昇降して上昇位置で上端開口が密閉されるようにするとともに、内外筒の間に昇降可能な支持筒を設けたものであり、まず、内筒を上昇させて上端開口を密閉した状態で、編成された筒状の靴下生地を口編部から内外筒の間の支持筒上に吸引し、こののち、内筒を下降させて支持筒上の靴下生地を爪先側から内筒にエアで吸引して裏返すようにしている。
【０００４】
一方、爪先部を縫合された靴下を表向きに裏返す装置としては、例えば、特開平６−３１６８６１号公報に記載されたものがある。この靴下の裏返し装置は、靴下の口編部を開口する手段と、第１部材および第２部材から成る裏返し手段を有し、第１部材を開口された口編部から爪先近傍まで挿入して、口編部から始まる空間を形成し、この空間を形成する第１部材の間に、棒状の第２部材を靴下の爪先側から第１部材と逆方向に口編部まで挿入することにより、第２部材に沿わせて靴下を裏返すものである。
【０００５】
また、この装置よりも以前から、逆方向に回転する平行な一対のローラ間に靴下を挟み、ローラ間から突き出す靴下の爪先に対向させて棒材をローラ間に前進させることにより、棒材に沿わせて靴下を裏返す装置も知られている。
【０００６】
【発明が解決しようとする課題】
上述した筒状の靴下生地の裏返し装置は、円型靴下編機の釜を利用するので、配置場所が限定されるとともに、各編機毎に１台ずつ配置する必要がある問題がある。また、２重の吸引筒を設けて、その内外筒の間に昇降可能な支持筒を配置する必要があるので、吸引機構が複雑になる問題もある。
【０００７】
一方、上述した爪先部を縫合された靴下の裏返し装置は、いずれも棒状部材を靴下の爪先部の生地に突き当てて前進させるので、生地を傷めやすい問題がある。特に、パイル生地の靴下は編目のループが長いので、棒状部材が引っ掛かりやすく、生地を傷めやすい。また、裏返された靴下が棒状部材に被さって残るので、この被さった靴下の除去に手間がかかり、つぎの靴下の裏返しに取り掛かるまでの時間ピッチが長くなって、靴下生産工場の生産性を阻害する問題もある。
【０００８】
そこで、この発明の課題は、生地を傷めることなく、靴下を簡単な機構で、迅速に裏返すことができる靴下の裏返し装置を提供することである。
【０００９】
【課題を解決するための手段】
上記の課題を解決するために、この発明の靴下の裏返し装置は、靴下の口編部を開口する開口手段と、開口された口編部を拡径する拡径手段と、口編部を拡径された靴下を吸引管の先端開口に被せるように装着する手段と、前記吸引管の先端開口に装着された靴下を、爪先側から吸引管の中にエアで吸引して裏返す手段とから成り、前記拡径手段を、軸断面の周方向に少なくとも３分割された軸棒部材を、合体させた状態で前記開口された口編部に先端側から挿入し、この挿入した軸棒部材を放射状に離反させて、この離反させた各軸棒部材の回りで口編部を拡径するものとした構成を採用した。
【００１０】
すなわち、開口手段で開口された靴下の口編部に、軸断面の周方向に少なくとも３分割された軸棒部材を、合体させた状態で先端側から挿入し、この挿入した軸棒部材を放射状に離反させて、この離反させた各軸棒部材の回りで口編部を拡径し、口編部を拡径した靴下を吸引管の先端開口に装着して、爪先側から吸引管の中にエアで吸引することにより、棒状部材等の突き当てで生地を傷めることなく、靴下を簡単な機構で、迅速に裏返すことができるようにした。
【００１１】
前記開口手段としては、前記靴下の口編部の対向する両縁部を把持して両側に拡げるものを採用することができる。
【００１２】
前記各軸棒部材を放射状に離反、合体させる手段としては、各軸棒部材の基端部を半径方向へスライド自在に案内するリニアウェイと、各軸棒部材の基端部に連結されるカムフォロワと、合体された軸棒部材の中心軸と同軸上で回転駆動され、回転に伴って前記各カムフォロワを半径方向へ直線駆動する複数のカム溝が設けられた板カムとから成り、この板カムを回転駆動することにより、前記各軸棒部材を半径方向へ直線移動させるものを採用することができる。
【００１３】
前記離反させた各軸棒部材の回りで拡径された口編部を、各軸棒部材との間で挟持する手段を設けることにより、離反させた各軸棒部材の回りからの口編部の抜け落ちを確実に防止することができる。
【００１４】
前記放射状に離反させて口編部を拡径した軸棒部材の基端側に、前記吸引管の先端開口を対向配置し、この対向配置した吸引管の先端開口側へ前記口編部を拡径した軸棒部材の基端側を相対直線移動させて、吸引管の先端開口を前記放射状に離反された軸棒部材の内径側に挿入することにより、口編部を拡径された靴下を吸引管の先端開口に被せるように装着することができる。
【００１５】
【発明の実施の形態】
以下、図１乃至図９に基づき、この発明の実施形態を説明する。この靴下の裏返し装置は、図１および図２に示すように、裏向きに裏返されて爪先部を縫合された靴下Ａが口編部を前方に向けて供給される樋状の受け部材１と、受け部材１の前端側に左右から進退し、口編部の対向する両縁部を把持して左右両側に拡げる開口装置２と、開口装置２で開口された口編部に向けて配置され、軸断面の周方向に分割された軸棒部材３を合体させた状態で口編部に先端側から挿入し、挿入した各軸棒部材３を放射状に離反させて口編部を拡径する拡径装置４と、各軸棒部材３の基端側に先端開口５ａを向けて配置された吸引管５と、拡径装置４を搭載した支持台６を、前面側の開口装置２と後面側の吸引管５とに向かって進退させる直線駆動装置７とで基本的に構成されている。直線駆動装置７は、リニアモータやサーボモータ（図示省略）により支持台６を案内レール７ａに沿って進退させるものである。
【００１６】
図３に示すように、開口装置２は、左右に延びる各案内レール８に案内されて、エアシリンダ９で左右に進退される一対の支持台１０の上端部に、それぞれチャック１１と口編部に当てられる当て板１２とを取り付けたものである。各案内レール８には、各支持台１０の進退限を位置決めするストッパ１３が取り付けられている。
【００１７】
図４に示すように、チャック１１は、上下一対の把持片１１ａ、１１ｂから成り、各把持片１１ａ、１１ｂがエアシリンダ１４により垂直面内で回動され、チャック１１の先端が当て板１２に設けられた窓１５の内側で噛み合わされる。各把持片１１ａ、１１ｂは、コイルばね１１ｃで開き方向に付勢され、当て板１２の背面側に押し当てられるストッパ１６が取り付けられており、チャック１１の先端が口編部の生地にあまり食い込まないようになっている。
【００１８】
図５乃至図７は、支持台６に搭載された拡径装置４を示す。支持台６には、直線駆動装置７の進退方向に向けた円筒部材１７が柱部材１８を介して取り付けられ、円筒部材１７の前進側端面には、背面側から吸引管５が通される中心孔１９が設けられた円板部材２０が取り付けられている。また、円筒部材１７の内周には、同じく吸引管５が通される中心孔２１が設けられた円盤状のカム２２が、クロスローラベアリング２３で回転自在に支持され、支持台６にブラケット２４ａを介して回動可能に取り付けられたエアシリンダ２４により回転駆動されるようになっている。
【００１９】
前記軸棒部材３は周方向に４分割され、分割された各軸棒部材３の先端部には、拡径された口編部を抜け難くする鉤状部３ａが形成されている。また、円板部材２０の背面側には、各軸棒部材３の基端部を半径方向へスライド自在に案内する４つのリニアウェイ２５が、９０°の位相で放射状に取り付けられている。円板部材２０の中心孔１９の外周には、各リニアウェイ２５の取り付け位相に合わせて、４つの切り込み部２６が形成されており、これらの切り込み部２６から各軸棒部材３の基端部が円板部材２０の背面側に挿入されて、各基端部に取り付けられたスライダ２７が各リニアウェイ２５に係止されている。各リニアウェイ２５には、カム２２のカム溝２８に嵌まり込んだカムフォロワ２９が連結されている。
【００２０】
前記カム溝２８は、図８に示すように、カム２２の前面側に、その中心孔２１の近くから外周側へ延びるように４本設けられ、カム２２の回転に伴って、各カム溝２８に嵌まり込んだカムフォロワ２９が、半径方向へ直線駆動されるようになっている。したがって、エアシリンダ２４でカム２２を正逆方向に回転駆動することにより、各カムフォロワ２９にスライダ２７を介して連結された各軸棒部材３が半径方向へ直線移動して、放射状に離反、合体する。各軸棒部材３の中心からの離反ストロークは、吸引管５の半径よりもある程度大きく設定されている。
【００２１】
図５および図６に示したように、円板部材２０の外径側前面には、各リニアウェイ２５の取り付け位相に合わせて４つのブラケット３０が取り付けられ、各ブラケット３０に２本の軸棒３１で半径方向へスライド自在に案内された挟持片３２が、コイルばね３３で内径側に向けて付勢されている。したがって、各カムフォロワ２９で各軸棒部材３が放射状に離反されたときに、各軸棒部材３の回りで拡径された口編部が、各挟持片３２で外周側から押圧されて挟持され、各軸棒部材３から抜け止めされる。なお、各挟持片３２は、軸棒３１に設けられたストッパ３４により、内径側下死点を吸引管５の半径よりも大きい位置に設定されており、各軸棒部材３が吸引管５の半径近くまで内径側に移動したときは、その回りの口編部の挟持を開放する。
【００２２】
以下に、図９に基づいて、受け部材１に供給される靴下Ａを裏返す手順を説明する。まず、開口装置２を受け部材１の前端側に左右から前進させて、靴下Ａの口編部の対向する両縁部を把持して左右両側に拡げる。
【００２３】
つぎに、図９（ａ）中に一点鎖線で示すように、各軸棒部材３を合体させた状態で、拡径装置４を直線駆動装置７により前進させて、合体させた軸棒部材３を開口装置２で開口された靴下Ａの口編部に挿入する。軸棒部材３が口編部に挿入されると、開口装置２は口編部の把持を開放し、左右の待機位置に後退する。こののち、拡径装置４のカム２２を正方向に回転駆動して、図９（ａ）に示すように、各カムフォロワ２９で各軸棒部材３を放射状に離反させ、その回りに靴下Ａの口編部を拡径する。このとき、拡径された口編部は、その外周側の各挟持片３２で挟持される。
【００２４】
つぎに、図９（ｂ）に示すように、拡径装置４を直線駆動装置７により後退させて、靴下Ａの口編部を拡径した各軸棒部材３の基端側を吸引管５の先端開口５ａの外周に嵌め込み、靴下Ａを爪先まで吸引管５の先端開口５ａに被せる。こののち、図９（ｂ）中に一点鎖線で示すように、拡径装置４のカム２２を僅かに逆方向に回転駆動して、各軸棒部材３を吸引管５の半径近くまで内径側に移動させ、さらに、拡径装置４をわずかに後退させることにより、各挟持片３２による挟持を開放された口編部が各軸棒部材３の先端から抜けて、靴下Ａが吸引管５の先端開口５ａに装着される。
【００２５】
最後に、吸引管５の先端開口５ａからエアを吸引することにより、図９（ｃ）に示すように、先端開口５ａに装着された靴下Ａを、爪先側から吸引管５の中に吸引して裏返す。靴下Ａの吸引が始まるのと同時に、図中に矢印で示すように、拡径装置４は開口装置２に向かって前進を開始し、吸引管５の先端開口５ａを通り過ぎたのち、カム２２が逆方向に回転駆動されて各軸棒部材３が合体され、合体された軸棒部材３が、開口装置２で開口されたつぎの靴下の口編部に挿入されて、靴下の裏返し作業が繰り返される。
【００２６】
上述した実施形態では、爪先部を縫合された靴下を裏返したが、この裏返し装置は、筒状の靴下生地も同様の手順で裏返すことができる。
【００２７】
また、上述した実施形態では、口編部を拡径した軸棒部材の基端側を吸引管の先端開口に向けて移動させることにより、靴下を吸引管の先端開口に装着したが、吸引管自身を前進させるか、吸引管の先端開口部を先端側へ延長可能として、吸引管の先端開口側を軸棒部材の基端側に向けて移動させ、靴下を吸引管の先端開口に装着するようにしてもよい。
【００２８】
さらに、周方向に分割した軸棒部材を放射状に離反、合体させる手段は、実施形態のカムを用いる方法に限定されることはなく、リンク機構や直線駆動装置等を用いる方法も採用することができる。なお、軸棒部材を４分割としたが、軸棒部材は周方向に少なくとも３分割以上されたものであればよい。
【００２９】
【発明の効果】
以上のように、この発明の靴下の裏返し装置は、開口手段で開口された靴下の口編部に、軸断面の周方向に少なくとも３分割された軸棒部材を、合体させた状態で先端側から挿入し、この挿入した軸棒部材を放射状に離反させて、この離反させた各軸棒部材の回りで口編部を拡径し、口編部を拡径した靴下を吸引管の先端開口に装着して、爪先側から吸引管の中にエアで吸引するようにしたので、棒状部材等の突き当てで生地を傷めることなく、靴下を簡単な機構で、迅速に裏返すことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for turning over a sock.
[0002]
[Prior art]
In general, socks are knitted in a tubular shape, turned upside down, sewn toe portions, and then turned upside down again to obtain a product.
[0003]
First, as a device for turning a cylindrical sock cloth upside down, for example, there is a device described in Japanese Patent Application Laid-Open No. Hei 4-263664. This sock turning device is arranged such that a double suction cylinder having an upper end opening is arranged inside a hook of a circular sock knitting machine so that the inner cylinder moves up and down so that the upper end opening is sealed at the ascending position. A support cylinder that can be raised and lowered is provided between the cylinders.First, the inner cylinder is raised and the upper end opening is sealed, and the knitted tubular sock cloth is placed between the mouth knitting part and the inner and outer cylinders. Suction is applied onto the support cylinder, and then the inner cylinder is lowered to suck the sock cloth on the support cylinder from the toe side into the inner cylinder by air and turn over.
[0004]
On the other hand, as a device for turning over a sock with a toe sewn upside down, there is, for example, a device described in Japanese Patent Application Laid-Open No. 6-316861. This device for turning over a sock has a means for opening a knitting portion of a sock, and a turning means comprising a first member and a second member, and inserts the first member from the opened knitting portion to the vicinity of the toe. By forming a space starting from the mouth knitting portion, and inserting the second bar-shaped member from the toe side of the sock to the mouth knitting portion in the opposite direction to the first member, between the first members forming the space. The sock is turned over along the second member.
[0005]
Also, before this device, a sock was sandwiched between a pair of parallel rollers rotating in the opposite direction, and the bar was advanced between the rollers in opposition to the toe of the sock protruding from between the rollers. A device for turning a sock upside down is also known.
[0006]
[Problems to be solved by the invention]
Since the above-mentioned tubular sock-cloth turning device uses a shuttle of a circular sock knitting machine, there is a problem that the arrangement place is limited and one unit must be arranged for each knitting machine. Further, since it is necessary to provide a double suction tube and arrange a vertically movable support tube between the inner and outer tubes, there is a problem that the suction mechanism becomes complicated.
[0007]
On the other hand, the above-mentioned device for turning over a sock to which the toe is sewn has a problem that the material is easily damaged because the rod-shaped member is moved forward by abutting the rod-shaped member against the material of the toe of the sock. In particular, the pile sock has a long stitch loop, so that the bar-shaped member is easily caught and the fabric is easily damaged. In addition, since the inverted sock is covered by the bar-shaped member and remains, it takes time to remove the covered sock, and the time pitch until the next sock is turned over becomes longer, which hinders the productivity of the sock production factory. There is also a problem to do.
[0008]
Accordingly, an object of the present invention is to provide a sock reversing device capable of quickly turning over a sock with a simple mechanism without damaging the fabric.
[0009]
[Means for Solving the Problems]
In order to solve the above problems, a sock flipping device according to the present invention includes opening means for opening a mouth knit portion of a sock, diameter expanding means for expanding the diameter of the opened mouth knit portion, and expanding the mouth knit portion. Means for attaching the diametered sock so as to cover the tip opening of the suction tube, and means for sucking the sock attached to the tip opening of the suction tube into the suction tube from the toe side with air and turning it over. The above-mentioned diameter expanding means is inserted from the tip side into the opened knitting portion in a state where the shaft rod member divided at least into three in the circumferential direction of the shaft cross section is united, and the inserted shaft rod member is radially inserted. And the diameter of the knitted portion was increased around each of the separated shaft rod members.
[0010]
That is, a shaft rod member divided at least into three parts in the circumferential direction of the shaft cross section is inserted into the mouth knit portion of the sock opened by the opening means from the front end side in a united state, and the inserted shaft rod member is radially inserted. The knitted portion is enlarged around each of the separated shaft rod members, and the sock with the enlarged knitted portion is attached to the tip opening of the suction pipe, and the toe side is inserted into the suction pipe. The sock can be quickly turned over with a simple mechanism without damaging the fabric by abutting a rod-shaped member or the like by sucking air.
[0011]
As the opening means, one that grips both opposing edges of the mouth knitting part of the sock and spreads it to both sides can be adopted.
[0012]
As means for radially separating and combining the shaft members, a linear way for guiding the base end of each shaft member slidably in the radial direction and a cam follower connected to the base end of each shaft member are provided. And a plate cam provided with a plurality of cam grooves which are driven to rotate coaxially with the central axis of the united shaft member, and which linearly drive the respective cam followers in the radial direction with the rotation. By rotationally driving the shaft members, the shaft members can be linearly moved in the radial direction.
[0013]
By providing a means for pinching the knitted portion expanded around each of the separated shaft rod members with each of the shaft members, the knitted portion from around each of the separated shaft members is provided. Can surely be prevented from falling off.
[0014]
A distal end opening of the suction tube is opposed to a base end side of the shaft rod member whose diameter is increased by radially separating the knitting portion, and the mouth knitting portion is expanded to a distal opening side of the opposedly arranged suction tube. By moving the proximal end side of the diameter shaft member relatively linearly, and inserting the distal end opening of the suction tube into the inner diameter side of the radially separated shaft member, the sock with the enlarged knitted portion is removed. It can be mounted so as to cover the tip opening of the suction tube.

Finally, by sucking air from the tip opening 5a of the suction tube 5, the sock A attached to the tip opening 5a is sucked into the suction tube 5 from the toe side as shown in FIG. And flip it over. Simultaneously with the start of the suction of the sock A, the diameter expanding device 4 starts to advance toward the opening device 2 as shown by an arrow in the figure, and after passing through the tip opening 5a of the suction tube 5, the cam 22 is moved. The respective shaft rod members 3 are rotated in the opposite direction to be combined, and the combined shaft rod members 3 are inserted into the knitting portion of the next sock opened by the opening device 2, and the work of turning the sock upside down is repeated. It is.
[0026]
In the above-described embodiment, the sock whose toe is sewn is turned upside down. However, this turning upside down device can turn a tubular sock cloth in the same procedure.
[0027]
Further, in the above-described embodiment, the sock is attached to the distal end opening of the suction tube by moving the base end side of the shaft rod member having the enlarged diameter of the mouth knit portion toward the distal end opening of the suction tube. Move itself forward or extend the distal opening of the suction tube to the distal side, move the distal opening of the suction tube toward the base end of the shaft member, and attach the sock to the distal opening of the suction tube. You may do so.
[0028]
Further, the means for radially separating and combining the shaft rod members divided in the circumferential direction is not limited to the method using the cam of the embodiment, and a method using a link mechanism, a linear drive device, or the like may be adopted. it can. Although the shaft rod member is divided into four parts, the shaft rod member may be any part as long as it is at least divided into three parts in the circumferential direction.
[0029]
【The invention's effect】
As described above, the device for turning over a sock according to the present invention is configured such that the shaft rod member divided at least into three in the circumferential direction of the shaft cross section is joined to the knitted portion of the sock opened by the opening means. And the inserted shaft member is radially separated, the diameter of the knitted portion is increased around each of the separated shaft members, and the sock with the expanded diameter of the mouth knit is opened at the tip opening of the suction tube. The socks can be quickly turned over with a simple mechanism without damaging the fabric by abutting a rod-shaped member or the like, since the socks are sucked into the suction tube by air from the toe side.
