Abstract
Description
この発明は、ヤーンキャリアと横編機及びマルチレイヤ編地の編成方法に関し、特に経糸とヤーンキャリアとの干渉を防止することに関する。 The present invention relates to a knitting method of a yarn carrier, a flat knitting machine and a multi-layer knitted fabric, and more particularly to preventing interference between a warp yarn and a yarn carrier.
特許文献1:特表2000-501792A(WO97/21860)は、横編機により、経糸の層と横糸の層を編糸で結合したマルチレイヤ編地を編成することを開示している。特許文献1では、経糸は横編機上方の供給手段から横編機の歯口へ供給し、横糸と編糸はヤーンキャリアから歯口に供給する。 Patent Document 1: Special Table 2000-501792A (WO97 / 21860) discloses knitting a multi-layer knitted fabric in which a warp layer and a weft layer are joined with a knitting yarn by a flat knitting machine. In Patent Document 1, the warp is supplied from the supply means above the weft knitting machine to the mouth of the weft knitting machine, and the weft and knitting yarn are supplied from the yarn carrier to the mouth.
発明者はここで、ヤーンキャリアを移動させると、ヤーンキャリア先端の給糸口が経糸と干渉することに着目した。経糸がヤーンキャリア先端の給糸口と干渉すると、経糸が歯口に沿ってシフトし、針床の針と接触しやすくなり、その結果編成が難しくなる。また仮に針と接触しないとしても、経糸の位置がシフトし編地が乱れる。 Here, the inventor paid attention to the fact that the yarn feeder at the tip of the yarn carrier interferes with the warp when the yarn carrier is moved. When the warp interferes with the yarn feeder at the tip of the yarn carrier, the warp shifts along the tooth mouth and easily comes into contact with the needles on the needle bed, resulting in difficult knitting. Even if it does not contact the needle, the position of the warp is shifted and the knitted fabric is disturbed.
この発明の課題は、経糸との干渉を防止できるヤーンキャリアを提供することにある。
この発明の課題は、経糸との干渉を防止できるヤーンキャリアを備えた横編機を提供することにある。
この発明の課題はさらに、経糸とヤーンキャリアとの干渉無しに、マルチレイヤ編地を編成することにある。
この発明の追加の課題は、ヤーンキャリアのガイド部材で反らせた経糸が針と干渉しないようにすることにある。
この発明の追加の課題はまた、ヤーンキャリアのガイド部材で反らせた経糸が他のヤーンキャリアの裏面に回り込まないようにすることにある。

この発明の横編機用のヤーンキャリアは、先端の給糸口から横編機の歯口に編糸もしくはインレイ糸(横糸)を供給するヤーンキャリアにおいて、給糸口よりもヤーンキャリアの基部寄りに、ヤーンキャリアから歯口側へ突き出し、かつ歯口を通過する経糸を歯口から見てヤーンキャリアとは反対側へガイドするガイド部材を備えていることを特徴とする。 The yarn carrier for a flat knitting machine of the present invention is a yarn carrier that supplies a knitting yarn or an inlay yarn (weft yarn) from the tip yarn feeder to the tooth mouth of the flat knitting machine, closer to the base of the yarn carrier than the yarn feeder, A guide member that protrudes from the yarn carrier to the side of the mouth and guides the warp passing through the mouth to the side opposite to the yarn carrier when viewed from the mouth is provided.
この発明の横編機は、少なくとも1枚の針床を備えて、針床先端に続くスペースを針床から出没する針により編目を形成する歯口とし、歯口に沿って移動し先端の給糸口から編糸もしくはインレイ糸を歯口に供給する複数のヤーンキャリアと、歯口に経糸を供給する供給手段とを備えた横編機において、各ヤーンキャリアは、給糸口よりもヤーンキャリアの基部寄りに、ヤーンキャリアから歯口側へ突き出し、かつ歯口を通過する経糸を歯口から見てヤーンキャリアとは反対側へガイドするガイド部材を備えていることを特徴とする。なおこの発明のヤーンキャリアと横編機は、経糸と編糸のみを供給し、インレイ糸を供給しない編成にも使用できる。その場合はマルチレイヤ編地ではなく、経糸と編糸とからなる編地が得られる。 The flat knitting machine of the present invention includes at least one needle bed, and uses a space that follows the needle bed tip to form a stitch by a needle that protrudes from the needle bed, and moves along the mouth to feed the tip. In a flat knitting machine comprising a plurality of yarn carriers for supplying knitting yarns or inlay yarns from a yarn mouth to a tooth mouth, and a supply means for supplying warps to the tooth mouth, each yarn carrier is a base of the yarn carrier rather than a yarn feeder. A guide member that protrudes from the yarn carrier toward the mouth of the mouth and guides the warp passing through the mouth to the side opposite to the yarn carrier when viewed from the mouth is provided. The yarn carrier and the flat knitting machine of the present invention can be used for knitting that supplies only warp and knitting yarn and does not supply inlay yarn. In that case, not a multi-layer knitted fabric but a knitted fabric composed of warp and knitting yarn is obtained.
この発明のマルチレイヤ編地の編成方法は、供給手段により針床先端に続くスペースからなる歯口に経糸を供給し、歯口に沿って移動するインレイ糸ヤーンキャリアの先端の給糸口からインレイ糸を歯口に供給し、歯口に沿って移動する編糸ヤーンキャリアの先端の給糸口から編糸を歯口に供給し、針床の針により編糸から編目を形成して経糸の層とインレイ糸の層を結合する編成方法において、各ヤーンキャリアは、給糸口よりもヤーンキャリアの基部寄りに、ヤーンキャリアから歯口側へ突き出すガイド部材を備え、ガイド部材により経糸を歯口から見てヤーンキャリアとは反対側へガイドすることを特徴とする。 In the knitting method of the multi-layer knitted fabric according to the present invention, the warp is supplied to the mouth formed of the space following the tip of the needle bed by the supply means, and the inlay yarn is fed from the yarn feeder at the tip of the inlay yarn carrier that moves along the mouth. Knitting yarn is supplied to the mouth from the yarn feeder at the tip of the knitting yarn carrier that moves along the mouth, and a warp layer is formed by forming a stitch from the knitting yarn with a needle in the needle bed. In the knitting method for joining the layers of inlay yarn, each yarn carrier is provided with a guide member that protrudes from the yarn carrier toward the mouth side closer to the base of the yarn carrier than the yarn feeder, and the warp is viewed from the mouth by the guide member. Guided to the opposite side of the yarn carrier.
この発明では、ヤーンキャリアのガイド部材により経糸を歯口の反対側へ反らせるので、ヤーンキャリア先端の給糸口が経糸と干渉しない。従ってマルチレイヤ編地等の編成が容易になる。 In this invention, since the warp is bent to the opposite side of the tooth opening by the guide member of the yarn carrier, the yarn feeder at the tip of the yarn carrier does not interfere with the warp. Therefore, knitting such as a multi-layer knitted fabric becomes easy.
好ましくは、ガイド部材は、中央に歯口の長手方向と平行な直線部を備え、直線部の左右両側に経糸を前記直線部へガイドするガイド部を備えている。なお直線部はインレイ糸用のヤーンキャリアには不要で、インレイ糸用のヤーンキャリアではガイド部を直線部を欠く弧状等の形状としても良い。直線部がないと、ガイド部材の中心部で、経糸は歯口の長手方向に水平面内で直角な方向、即ち針の出没方向のみでなく、歯口の長手方向にも傾斜する。ヤーンキャリアから編糸を供給すると、ヤーンキャリアの進行方向の直後方で針床の針により、編糸を捕捉して編目を形成する。ここで経糸が歯口の長手方向に傾斜すると、針が経糸と衝突する、あるいは針が経糸を捕捉するなどのトラブルが生じる。これに対して編糸供給用のヤーンキャリアのガイド部材の端面中央部に直線部を設けると、ガイドされる経糸は歯口の長手方向に沿って傾斜しない。従って上記のトラブルを解消できる。 Preferably, the guide member includes a linear portion parallel to the longitudinal direction of the tooth opening at the center, and guide portions for guiding the warp to the linear portion on the left and right sides of the linear portion. The straight portion is not necessary for the inlay yarn carrier, and the guide portion of the inlay yarn carrier may have an arc shape or the like lacking the straight portion. If there is no straight part, the warp is inclined not only in the direction perpendicular to the longitudinal direction of the tooth mouth in the horizontal plane, that is, in the longitudinal direction of the tooth mouth, but also in the direction in which the needle protrudes and retracts. When the knitting yarn is supplied from the yarn carrier, the knitting yarn is captured by the needle in the needle bed immediately after the traveling direction of the yarn carrier to form a stitch. Here, when the warp is inclined in the longitudinal direction of the tooth opening, troubles such as the needle colliding with the warp or the needle capturing the warp occur. On the other hand, when a straight portion is provided at the center of the end face of the guide member of the yarn carrier for supplying knitting yarn, the warp to be guided is not inclined along the longitudinal direction of the tooth mouth. Therefore, the above trouble can be solved.
また好ましくは、ガイド部は、ヤーンキャリアよりも歯口から離れた位置から経糸のガイドを開始する形状をしている。歯口から離れたとは、直線状の歯口に対し、ガイド部材の高さの位置で、平面視においてヤーンキャリアよりも歯口から離れた箇所からガイド部が始まることを意味する。針床を前後一対以上設ける場合、針床間のスペースの中心が歯口中心線で、歯口中心線に対してヤーンキャリアよりも離れた位置から、ガイドを開始する。このためにはガイド部材の左右に、ヤーンキャリアの裏面よりも歯口から遠い位置まで伸びる後退部を設けると良い。このようにすると、他のヤーンキャリアにより反らされた経糸がヤーンキャリアの裏面へ回り込むことがない。 Further preferably, the guide portion has a shape in which the guide of the warp is started from a position farther from the mouth than the yarn carrier. To be away from the mouth means that the guide portion starts from a position farther from the mouth than the yarn carrier in a plan view at the height of the guide member with respect to the straight mouth. When a pair of front and back needle beds are provided, the center of the space between the needle beds is the tooth center line, and the guide is started from a position away from the yarn carrier with respect to the tooth center line. For this purpose, it is preferable to provide a retracted portion on the left and right sides of the guide member that extends to a position farther from the tooth opening than the back surface of the yarn carrier. In this way, the warp warped by another yarn carrier does not wrap around the back surface of the yarn carrier.
好ましくは、横編機の側面視で、歯口の左右双方にヤーンキャリアを配置し、左右のヤーンキャリアでガイド部材の高さを異ならせる。このようにすると向き合ったヤーンキャリア間でガイド部材が干渉しないので、これらのヤーンキャリアがクロスするように移動させることができる。従って、例えばインレイ糸供給用のヤーンキャリアを先行、編糸供給用のヤーンキャリアを後行として、ヤーンキャリアを移動させることができ、編成効率を向上させることができる。仮にガイド部材が互いに干渉すると、インレイ糸供給用のヤーンキャリアを先行、編糸供給用のヤーンキャリアを後行として1コース編成した後、次のコースでは編糸供給用のヤーンキャリアが先行、インレイ糸供給用のヤーンキャリアが後行となる。
Preferably, in the side view of the flat knitting machine, the yarn carriers are arranged on both the left and right sides of the tooth opening, and the heights of the guide members are made different between the left and right yarn carriers. In this way, since the guide member does not interfere between the yarn carriers facing each other, the yarn carriers can be moved so as to cross. Therefore, for example, the yarn carrier can be moved with the yarn carrier for supplying inlay yarn as the leading and the yarn carrier for supplying knitting yarn as the trailing, so that the knitting efficiency can be improved. If the guide members interfere with each other, one course knitting is performed with the yarn carrier for supplying inlay yarn preceding and the yarn carrier for supplying knitting yarn following, and then the yarn carrier for supplying knitting yarn precedes and inlays in the next course. The yarn carrier for supplying yarn is followed.
以下に、発明を実施するための最適実施例を示す。この発明の範囲は、特許請求の範囲の記載に、周知技術による変更の可能性を加味して解釈されるべきである。 In the following, an optimum embodiment for carrying out the invention will be shown. The scope of the present invention should be construed in consideration of the possibility of modification by well-known techniques in the description of the scope of claims.
図1〜図9に、実施例を示す。図において、2は横編機で、例えば前針床Fと後針床Rとを備えるが、前針床Fのみでもよく、あるいは針床を前後上下に4枚など、より多数備えても良い。前後の針床F,R間の歯口3には経糸4が上下方向に通され、インレイ糸(横糸)6がヤーンキャリア10で供給され、編糸8がヤーンキャリア12で供給される。歯口3は針床の先端に続くスペースで、針床F,Rの針の出没方向に水平面内で直角に延び、針床F,Rの長手方向に平行である。歯口の中心という場合、針の出没方向に関する歯口の中心を言う。また歯口中心線は針床F,R間のスペースの中心にあり、針床F,Rの長手方向に平行な線である。経糸4は例えばカーボンファイバー,ガラスファイバー,アラミドファイバーなどから成り、特に強度が高く曲げが困難なカーボンファイバーが好ましい。インレイ糸6はガラスファイバーあるいはアラミドファイバーなどから成り、特に屈折が容易なアラミドファイバーが好ましい。ヤーンキャリア10はインレイ糸6を供給するが、針床F,Rの針はインレイ糸6に対しては編成動作を行わない。編糸8はヤーンキャリア12から供給され、針床F,Rの針による編成動作を受けて、編目(ニードルループ)と渡り糸(シンカーループ)とになり、経糸4とインレイ糸6を互いに結びつける。 An example is shown in FIGS. In the figure, reference numeral 2 denotes a flat knitting machine, which includes, for example, a front needle bed F and a rear needle bed R. However, only the front needle bed F may be provided, or a larger number of needle beds may be provided such as four in the front and rear and up and down directions. . A warp 4 is passed in the vertical direction between the front and back needle beds F and R, an inlay yarn (weft yarn) 6 is supplied by a yarn carrier 10, and a knitting yarn 8 is supplied by a yarn carrier 12. The tooth opening 3 is a space following the tip of the needle bed, and extends at right angles in the horizontal plane in the direction in which the needles of the needle beds F and R protrude and is parallel to the longitudinal direction of the needle beds F and R. When referring to the center of the mouth, it refers to the center of the mouth with respect to the direction of the needle. In addition, the center line of the mouth is at the center of the space between the needle beds F and R, and is a line parallel to the longitudinal direction of the needle beds F and R. The warp 4 is made of, for example, carbon fiber, glass fiber, aramid fiber, etc., and carbon fiber that is particularly strong and difficult to bend is preferable. The inlay yarn 6 is made of glass fiber or aramid fiber, and is particularly preferably an aramid fiber that can be easily refracted. The yarn carrier 10 supplies the inlay yarn 6, but the needles of the needle beds F and R do not perform the knitting operation on the inlay yarn 6. The knitting yarn 8 is supplied from the yarn carrier 12 and is subjected to the knitting operation by the needles of the needle beds F and R to become a stitch (needle loop) and a transition yarn (sinker loop), and the warp yarn 4 and the inlay yarn 6 are connected to each other. .
図2は経糸4を供給するための治具14を示し、治具14には例えば多数の孔があり、この孔を経糸4が上から下へと通過して歯口3へ供給される。実施例では強化ファイバーとして経糸4とインレイ糸6とを供給するが、これ以外に斜めに強化ファイバーを供給することもでき、その場合、例えば治具14から編地の斜め上から針床F,Rへ供給する。あるいは編地を、針床F,R間の目移しと針床のラッキングとにより、針床F,Rの長手方向に沿って移動させても、斜めに強化ファイバーを通すことができる。複数本の平行な経糸4は経糸の層を成し、複数本の平行なインレイ糸6はインレイ糸の層を成し、斜めに糸を供給する場合、これらに斜めの糸の層が加わる。斜めの糸は、例えば水平方向から45°傾いた方向と135°傾いた方向の2方向に配置する。 FIG. 2 shows a jig 14 for supplying the warp 4. The jig 14 has, for example, a large number of holes, and the warp 4 passes from the top to the bottom and is supplied to the tooth opening 3. In the embodiment, the warp yarn 4 and the inlay yarn 6 are supplied as reinforcing fibers, but the reinforcing fiber can also be supplied obliquely. In this case, for example, the needle bed F, Supply to R. Alternatively, even if the knitted fabric is moved along the longitudinal direction of the needle beds F and R by transferring between the needle beds F and R and racking the needle beds, the reinforcing fibers can be passed diagonally. The plurality of parallel warp yarns 4 form a warp layer, and the plurality of parallel inlay yarns 6 form an inlay yarn layer, and when supplying the yarn diagonally, an oblique yarn layer is added to them. The slanted yarn is arranged in two directions, for example, a direction inclined 45 ° from the horizontal direction and a direction inclined 135 °.
図3にマルチレイヤ編地の構造を示し、図の上から下への順に経糸4の層とインレイ糸6の層と編目16の層とがあり、経糸4の層は歯口の中心付近にあり、歯口の中心から一方に寄った位置にインレイ糸6の層があり、編目16の層はインレイ糸6の層よりも歯口の中心から外れた側にある。編目16,16間の渡り糸18は経糸4とインレイ糸6を編目16に結び付け、編目16と渡り糸18とで経糸4の層とインレイ糸6の層を結合する。17は1コース前の編目で、編目16をインレイ糸6の図3での下側に固定する。図3の構造の編地から経糸4を除くと、一種のインレイ編地となる。なお通常のインレイ編地では、図3の経糸4の位置でも編目を形成してリブ編地とする。 FIG. 3 shows the structure of the multi-layered knitted fabric. There are a warp 4 layer, an inlay yarn 6 layer, and a stitch 16 layer in order from the top to the bottom of the drawing. There is a layer of the inlay yarn 6 at a position closer to one side from the center of the tooth opening, and the layer of the stitch 16 is on the side farther from the center of the tooth opening than the layer of the inlay yarn 6. The transition yarn 18 between the stitches 16, 16 connects the warp 4 and the inlay yarn 6 to the stitch 16, and the stitch 16 and the transition yarn 18 join the layers of the warp 4 and the inlay yarn 6. Reference numeral 17 denotes a stitch one course before, and the stitch 16 is fixed to the lower side of the inlay yarn 6 in FIG. When the warp 4 is removed from the knitted fabric having the structure shown in FIG. 3, a kind of inlay knitted fabric is obtained. In a normal inlay knitted fabric, a stitch is formed even at the position of the warp 4 in FIG. 3 to form a rib knitted fabric.
図3の編地を編成するには、例えば歯口の中心を通るように経糸4を治具から供給し、インレイ糸6の供給用のヤーンキャリアを先行して歯口に沿って移動させ、インレイ糸6を供給する。次いで、経糸4から見てインレイ糸6の反対側(図3の上側)に沿って、歯口に平行に編糸の供給用のヤーンキャリアを移動させ、針床の針で編目16を形成する。以上のようにインレイ糸供給用のヤーンキャリア10が先行し、編糸供給用のヤーンキャリア12が後行する。キャリッジの1コースの間に、インレイ糸6を供給し、編目16を編成して、経糸4とインレイ糸6とを編み込むことができる。従って効率的に編成できる。またインレイ糸供給用のヤーンキャリア10と編糸供給用のヤーンキャリア12は、歯口中心線の左右に、横編機の側面視で互いに向き合うように配置する。例えば針床の針を選択し、経糸4の正面にある針は動作させず、経糸4と経糸4の間の針を動作させて、編目16を形成する。なお針の配置間隔が広い場合、経糸4を針と針の間に配置して、全ての針を動作させることもできる。 In order to knit the knitted fabric of FIG. 3, for example, the warp 4 is supplied from the jig so as to pass through the center of the mouth, and the yarn carrier for supplying the inlay yarn 6 is moved along the mouth in advance. Inlay yarn 6 is supplied. Next, the yarn carrier for supplying the knitting yarn is moved along the opposite side of the inlay yarn 6 as viewed from the warp yarn 4 (upper side in FIG. 3) in parallel with the tooth opening, and the stitch 16 is formed by the needles on the needle bed. . As described above, the yarn carrier 10 for supplying the inlay yarn precedes, and the yarn carrier 12 for supplying the knitting yarn follows. During one course of the carriage, the inlay yarn 6 can be supplied, the stitch 16 can be knitted, and the warp yarn 4 and the inlay yarn 6 can be knitted. Therefore, it can be efficiently organized. Further, the yarn carrier 10 for supplying inlay yarn and the yarn carrier 12 for supplying knitting yarn are arranged on the left and right sides of the center line of the tooth mouth so as to face each other in a side view of the flat knitting machine. For example, the stitch 16 is formed by selecting a needle on the needle bed and operating the needle between the warp 4 and the warp 4 without operating the needle in front of the warp 4. In addition, when the arrangement | positioning space | interval of a needle | hook is wide, all the needle | hooks can also be operated by arrange | positioning the warp 4 between a needle | hook.
図4,図5にマルチレイヤ編地の組織を示す。図4では、経糸4の層の前針床F側にインレイ糸6の層が有り、さらに前針床F側に編目16の層がある。そして渡り糸18が経糸4の後側を通ることにより、経糸4の層とインレイ糸6の層を編目16の層に結合する。図4では、例えば前針床Fの針のみでマルチレイヤ編地を編成でき、編目16の編組織は平編である。 4 and 5 show the structure of the multilayer knitted fabric. In FIG. 4, the inlay yarn 6 layer is on the front needle bed F side of the warp yarn layer 4, and the stitch 16 layer is on the front needle bed F side. The crossover yarn 18 passes through the rear side of the warp 4, thereby joining the layer of the warp 4 and the layer of the inlay yarn 6 to the layer of the stitch 16. In FIG. 4, for example, a multilayer knitted fabric can be knitted only with the needles of the front needle bed F, and the knitting structure of the stitch 16 is a flat knitting.
図5では、リブ編地を用いてマルチレイヤ編地を編成する。前針床Fと後針床Rとの間に経糸4の層があり、その両側に一対のインレイ糸6,7を配置する。また編糸として一対の編糸8,9を用い、これらをリブ編成する。各編糸8,9により、前針床F側と後針床R側とに編目16を形成し、この間の渡り糸18,19により、経糸4とインレイ糸6,7を編目16の層に結合する。 In FIG. 5, a multi-layer knitted fabric is knitted using a rib knitted fabric. There is a layer of warp 4 between the front needle bed F and the rear needle bed R, and a pair of inlay yarns 6 and 7 are arranged on both sides thereof. Further, a pair of knitting yarns 8 and 9 are used as knitting yarns, and these are knitted with ribs. The stitches 16 are formed on the front needle bed F side and the rear needle bed R side by the respective knitting yarns 8 and 9, and the warp yarn 4 and the inlay yarns 6 and 7 are formed in the layer of the stitch 16 by the transition yarns 18 and 19 therebetween. Join.
実施例では、歯口3の付近で経糸4がヤーンキャリア10,12先端のチップ24に設けた給糸口25と干渉する恐れがある。即ち、歯口3を上下に通過する経糸4が、ヤーンキャリア10,12、特にヤーンキャリア10,12の先端のチップ24と、給糸口25の付近で接触して運ばれ、あるいは歯口3を通過する位置がシフトする恐れがある。経糸4の位置がシフトすると、針床から進出する針と衝突し、あるいは針に捕捉される可能性があり、また仮に針と接触しないにしても、編地が乱れる可能性がある。経糸4がヤーンキャリア10,12先端の給糸口25と干渉することを防止するための機構を、図6〜図8に示す。 In the embodiment, the warp 4 may interfere with the yarn feeder 25 provided on the tip 24 at the tip of the yarn carriers 10 and 12 in the vicinity of the mouth 3. That is, the warp yarn 4 passing up and down the tooth mouth 3 is carried in contact with the yarn carrier 10, 12, particularly the tip 24 at the tip of the yarn carrier 10, 12 in the vicinity of the yarn feeder 25, or The passing position may shift. When the position of the warp 4 is shifted, it may collide with a needle that advances from the needle bed or be captured by the needle, and even if it does not contact the needle, the knitted fabric may be disturbed. A mechanism for preventing the warp 4 from interfering with the yarn feeder 25 at the tips of the yarn carriers 10 and 12 is shown in FIGS.
図6〜図8に示すように、ヤーンキャリア10,12にプレート状のガイド部材26を設けて、経糸4をガイドする。図6に示すように、針20,21は針床F,Rから出没し、ヤーンキャリア12から供給する編糸8により編目を形成する。またヤーンキャリア10,12は先端にチップ24を備え(図8)、チップ24の給糸口25を通って、インレイ糸6と編糸8が供給される。ガイド部材26はヤーンキャリア10,12に板状の取付部34でボルト36とナット38等により固着され、固着の手段は任意である。ガイド部材26はヤーンキャリア10,12から歯口3の中央方向へ突き出した突出部28を備え、経糸4と接触すると突出部28の端面に沿って経糸4を反らせる。この結果、経糸4をチップ24の給糸口25等と干渉させずに、ヤーンキャリア10,12が通過できる。 As shown in FIGS. 6 to 8, a plate-like guide member 26 is provided on the yarn carriers 10 and 12 to guide the warp 4. As shown in FIG. 6, the needles 20 and 21 protrude from the needle beds F and R, and form stitches by the knitting yarn 8 supplied from the yarn carrier 12. Further, the yarn carriers 10 and 12 have a tip 24 at the tip (FIG. 8), and the inlay yarn 6 and the knitting yarn 8 are supplied through the yarn feeder 25 of the tip 24. The guide member 26 is fixed to the yarn carriers 10 and 12 with a plate-like mounting portion 34 by means of a bolt 36 and a nut 38, and the fixing means is arbitrary. The guide member 26 includes a protruding portion 28 protruding from the yarn carriers 10 and 12 toward the center of the tooth mouth 3, and warps the warp 4 along the end surface of the protruding portion 28 when contacting the warp 4. As a result, the yarn carriers 10 and 12 can pass without causing the warp yarn 4 to interfere with the yarn feeder 25 of the tip 24 and the like.
図7に示すように、突出部28の中央に歯口に平行な直線状の端部からなる直線部30があり、その左右に直線部30へと経糸をガイドするガイド部31がある。直線部30の長さwは、針20,21の操作用の図示しないキャリッジ等により、針が針床F,Rから進出する区間の長さの最大で2倍程度とし、より短くても良い。この長さは歯口に沿った長さで、針の配列ピッチと、キャリッジが同時に針床F,Rから進出させる針の本数の積で定まる。また左右のガイド部31,31の部分で突出部28に連続して後退部32,32を設け、後退部32はヤーンキャリア10,12の裏面(歯口と反対側の面)よりも、歯口から遠ざかっている。なおインレイ糸6用のヤーンキャリア10では、直線部30を設けなくても良い。 As shown in FIG. 7, there is a linear portion 30 formed of a linear end parallel to the tooth opening at the center of the protruding portion 28, and a guide portion 31 that guides the warp yarn to the linear portion 30 on the left and right thereof. The length w of the straight portion 30 is about twice as long as the length of the section in which the needle advances from the needle beds F and R by a carriage (not shown) for operating the needles 20 and 21, and may be shorter. . This length is the length along the tooth opening, and is determined by the product of the needle arrangement pitch and the number of needles that the carriage advances from the needle beds F and R simultaneously. Further, the left and right guide portions 31, 31 are provided with receding portions 32, 32 continuously from the projecting portion 28, and the receding portions 32 have teeth on the back side of the yarn carriers 10, 12 (the surface opposite to the mouth). It is away from the mouth. In the yarn carrier 10 for the inlay yarn 6, the straight portion 30 may not be provided.
図6に戻り、歯口の左右に配置された向かい合うヤーンキャリア10,12で、ガイド部材26の取り付け高さを異ならせる。なおヤーンキャリア10,12は経糸4の列(歯口中心線)の左右に例えば数本ずつ設けることができ、経糸4の列から見て同じ側にあるヤーンキャリアはガイド部材26の高さを共通にしても異ならせても良い。 Returning to FIG. 6, the mounting heights of the guide member 26 are made different between the yarn carriers 10, 12 facing each other on the left and right sides of the mouth. For example, several yarn carriers 10 and 12 can be provided on the left and right sides of the row of warps 4 (the center of the mouth), and the yarn carriers on the same side as seen from the rows of warps 4 have the height of the guide member 26 increased. It may be common or different.
図8に示すように、ヤーンキャリア10,12の上部(基部)には連行部40があり、例えば図示しないヤーンキャリアレールに沿って、歯付ベルト41と従動ローラ42で、ヤーンキャリア10,12を移動させる。ヤーンキャリア10,12は、針の操作用のキャリッジと共に移動する部材から出没するピンなどで連行しても良い。 As shown in FIG. 8, there is an entrainment portion 40 at the upper part (base) of the yarn carriers 10 and 12, for example, along the yarn carrier rail (not shown) by the toothed belt 41 and the driven roller 42. Move. The yarn carriers 10 and 12 may be carried by a pin or the like that protrudes and protrudes from a member that moves together with the carriage for operating the needle.
ガイド部材26の作用を示す。図7に示すように、ヤーンキャリア10,12が移動すると、経糸4はガイド部31に接触して、ヤーンキャリアから見て歯口中心線39の反対側へ反るようにガイドされ、直線部30を介して、次のガイド部31へとガイドされる。このため図6に示すように、チップ24と経糸4との接触を防止できる。 The operation of the guide member 26 is shown. As shown in FIG. 7, when the yarn carriers 10 and 12 move, the warp 4 comes into contact with the guide portion 31 and is guided so as to warp to the opposite side of the tooth center line 39 as viewed from the yarn carrier, and the straight portion It is guided to the next guide portion 31 through 30. For this reason, as shown in FIG. 6, the contact between the tip 24 and the warp 4 can be prevented.
ガイド部材26で経糸4をガイドする際に、直線部30以外の箇所では、経糸4が歯口の長手方向にもシフトする。経糸4が歯口の長手方向にシフトすると、針床F,Rから進出する針と干渉するおそれがある。ここで直線部30では、経糸4は歯口の長手方向にシフトしないので、針と干渉しない。なお一般に、針は、ヤーンキャリア12の運動方向中心からその直後の範囲から、数本程度が進出する。この区間を図7に模式的に半円で示す。そこで直線部30の長さがこの区間の長さの2倍以上あれば、歯口の長手方向に傾斜した経糸4と針が接触するおそれはない。また針の先端が歯口中心線39付近まで進出しないと、針は経糸4と接触しないので、直線部30の長さはより短くてもよい。なおインレイ用のヤーンキャリア10の下部で針が進出することはないので、直線部30は編糸用のヤーンキャリア12にのみ設ければよい。 When the warp 4 is guided by the guide member 26, the warp 4 is also shifted in the longitudinal direction of the tooth mouth at portions other than the straight portion 30. When the warp 4 is shifted in the longitudinal direction of the mouth, there is a risk of interference with the needles that advance from the needle beds F and R. Here, in the straight portion 30, the warp 4 does not shift in the longitudinal direction of the mouth and thus does not interfere with the needle. In general, several needles advance from the range immediately after the center of the yarn carrier 12 in the movement direction. This section is schematically shown as a semicircle in FIG. Therefore, if the length of the straight portion 30 is at least twice as long as the length of this section, there is no possibility that the warp 4 and the needle inclined in the longitudinal direction of the mouth are in contact with each other. If the tip of the needle does not advance to the vicinity of the tooth center line 39, the needle does not contact the warp 4, so the length of the straight portion 30 may be shorter. Since the needle does not advance below the inlay yarn carrier 10, the straight portion 30 may be provided only on the yarn carrier 12 for knitting yarn.
経糸4が直線部30でガイドされている際に、ヤーンキャリア10,12が向かい合うヤーンキャリア12,10とクロスすると、経糸4が向かい合うヤーンキャリア12,10の裏面へ運ばれるおそれがある。そこで左右の後退部32,32を設け、ヤーンキャリア12,10の裏面よりも歯口中心線39から離れた位置から、経糸4の直線部30へのガイドが始まるようにすると、経糸4がヤーンキャリア12,10の裏面へ運ばれることがない。 When the warp 4 is guided by the straight portion 30, if the yarn carriers 10, 12 cross the opposing yarn carriers 12, 10, the warp 4 may be conveyed to the back of the opposing yarn carriers 12, 10. Therefore, when the left and right retreating portions 32 and 32 are provided so that the guide to the straight portion 30 of the warp 4 starts from a position farther from the center line 39 than the back surface of the yarn carriers 12 and 10, the warp 4 is It is not carried to the back surface of the carriers 12 and 10.
向かい合うヤーンキャリア10,12がクロスする際に、ガイド部26が衝突しないようにする必要がある。そこでガイド部26を高さを変えて、向かい合うヤーンキャリア10,12に取り付ける。 It is necessary to prevent the guide portion 26 from colliding when the yarn carriers 10 and 12 facing each other cross. Therefore, the guide portion 26 is attached to the yarn carriers 10 and 12 facing each other at different heights.
ガイド部材26を設ける代わりに、歯口3の幅を大きくし、ヤーンキャリア10,12の先端に取り付けたチップ24の付近で、経糸4がチップ24と接触しないようにすることも、発明者は検討した。ただしこのようにすると、大きな編目が形成されるので、編目の層が緩む。従ってガイド部材26により経糸4を歯口の反対側に反らせる。また発明者は、治具14を前針床Fと後針床R間で揺動させることも検討した。例えば、ヤーンキャリア10でインレイ糸6を供給する際には、治具14を後針床R側へ揺動させることにより、経糸14と干渉しないようにし、ヤーンキャリア12で編糸を供給する際には治具14を前針床F側へ揺動させることにより、経糸4と干渉しないようにすることを検討した。しかしこのようにすると、治具14をヤーンキャリア10,12の移動と同期して揺動させる機構が必要になる、また治具14が反対方向に揺動できるように、治具14の付近を通過する時間を、ヤーンキャリア10とヤーンキャリア12とでずらせる必要がある。従って編成効率が低下する。 Instead of providing the guide member 26, the inventor can also increase the width of the mouth 3 so that the warp 4 does not contact the tip 24 in the vicinity of the tip 24 attached to the tips of the yarn carriers 10 and 12. investigated. However, if this is done, a large stitch is formed, so that the stitch layer is loosened. Accordingly, the warp 4 is warped to the opposite side of the tooth opening by the guide member 26. Further, the inventor also examined rocking the jig 14 between the front needle bed F and the rear needle bed R. For example, when the inlay yarn 6 is supplied by the yarn carrier 10, the jig 14 is swung to the rear needle bed R side so as not to interfere with the warp yarn 14, and the yarn carrier 12 is supplied with the knitting yarn. In order to avoid interference with the warp yarn 4, the jig 14 was swung to the front needle bed F side. However, in this case, a mechanism for swinging the jig 14 in synchronization with the movement of the yarn carriers 10 and 12 is required, and the vicinity of the jig 14 is arranged so that the jig 14 can swing in the opposite direction. It is necessary to shift the passing time between the yarn carrier 10 and the yarn carrier 12. Therefore, the knitting efficiency is reduced.
図9は螺旋状に編成したマルチレイヤ編地を示し、ここでは経糸及びインレイ糸として組紐状の糸を用いているが、これは試作編地だからである。図9でマルチレイヤ編地の前後から延びている組紐状の糸が経糸で、マルチレイヤ編地の横方向に沿って折り返している組み紐状の糸がインレイ糸である。マルチレイヤ編地が螺旋状になっているのは、引き返し編成により、編幅の内側と外側とで編目の数が異なるためで、編幅の内側では編目の数が少なく、外側では多い。このためマルチレイヤ編地は編目の少ない側を内側に、多い側を外側にカールし、図9の形態となる。図9のマルチレイヤ編地は、長い場合は螺旋状となり、短い場合は螺旋の一部の形状となる。 FIG. 9 shows a multi-layer knitted fabric knitted in a spiral shape. Here, braided yarns are used as warp yarns and inlay yarns because this is a trial knitted fabric. In FIG. 9, the braided yarn extending from the front and back of the multilayer knitted fabric is a warp yarn, and the braided yarn folded back along the lateral direction of the multilayer knitted fabric is an inlay yarn. The reason why the multi-layer knitted fabric is spiral is that the number of stitches is different between the inside and outside of the knitting width due to turn-back knitting, so the number of stitches is small inside the knitting width and many outside. For this reason, the multi-layer knitted fabric curls the side with few stitches inward and the side with many stitches outward, resulting in the form of FIG. The multi-layer knitted fabric of FIG. 9 has a spiral shape when it is long and a partial shape of the spiral when it is short.
