Description

本発明は、横編機で編地を編成する際に、編針と協働して編目を形成するために用いられる可動シンカーに関する。 The present invention relates to a movable sinker used to form stitches in cooperation with knitting needles when knitting a fabric with a flat knitting machine.

従来から、固定シンカーと可動シンカーとを備える横編機では、編針のフックでニードルループとなる編糸を引き込むとともに、固定シンカーの歯口側の側縁にシンカーループとなる編糸を掛け、新たな編目を形成する。形成された編目は可動シンカーで歯口下方に押し込む。固定シンカーは、天歯となる歯口ワイヤーの支持も行う。新たな編目を形成する際に、先に形成されていた旧編目は、歯口ワイヤーの位置を基準にノックオーバーされ、安定した風合いの編地を得ることができると期待される(たとえば、特許文献1参照)。編目の形成を安定して行うためには、旧編目以下、すでに編成された編地を歯口下方に引き下げることも必要となる。編地の引き下げは、歯口下方に設置される編地引下げ装置などで行われるけれども、可動シンカーで歯口から垂れ下がる編地を引き下げることも提案されている(たとえば、特許文献2参照)。 Traditionally, flat knitting machines equipped with a fixed sinker and a movable sinker draw in the knitting yarn that will become the needle loop with the hook of the knitting needle, and hang the knitting yarn that will become the sinker loop on the side edge of the fixed sinker on the tooth opening side to create a new knitting machine. form a stitch. The formed stitch is pushed below the tooth opening with a movable sinker. The fixed sinker also supports the mouth wire that will become the top tooth. When forming a new stitch, the previously formed old stitch is knocked over based on the position of the gap wire, and it is expected that a knitted fabric with a stable texture can be obtained (for example, in the patent (See Reference 1). In order to form stitches stably, it is also necessary to pull down the already knitted fabric below the stitch gap below the old stitch. Although the knitted fabric is pulled down using a knitted fabric pulling device installed below the stitch gap, it has also been proposed to use a movable sinker to pull down the knitted fabric hanging from the stitch gap (for example, see Patent Document 2).

横編機で編成する編地は、ピンタックや引き返し編成など、編地が歯口で浮いたり滞留したりして、歯口下方まで下がり難いものもある。これら難編成組織の編地は、特許文献1のような可動シンカーと固定シンカーとの併用だけでは、可動シンカーによる新編目の押し込みが歯口ワイヤーまでであるので、安定した編成が困難になる。特許文献1の可動シンカーに特許文献2のような編地引下げの機能を付加することが可能なら、難編成組織も容易に編成可能になると期待される。しかしながら、特許文献2の可動シンカーは、前後の針床が対向する歯口中央で、前後の可動シンカー間に編地を挟んで引き下げる必要がある。ただし、編地を両側の針床から挟む方式であるので、編地の厚みなどの変化への対応が困難である。また、筒状編地などの前後編地は一緒に挟まれ、可動シンカーが開いても歯口内に留まるので、針床を長手方向に移動させて前後の対向位置をずらすラッキング時に編地を引っ掛けるおそれがある。 Some knitted fabrics knitted with flat knitting machines, such as pintuck and flechage knitting, float or stagnate at the stitch gap and are difficult to move down to the bottom of the stitch gap. These knitted fabrics with a difficult-to-knit structure are difficult to stably knit simply by using a movable sinker and a fixed sinker in combination as in Patent Document 1, because the movable sinker can only push new stitches up to the gap wire. If it is possible to add the knitted fabric pull-down function as in Patent Document 2 to the movable sinker in Patent Document 1, it is expected that difficult-to-knit structures can be easily knitted. However, in the movable sinker of Patent Document 2, it is necessary to sandwich the knitted fabric between the front and rear movable sinkers and pull it down at the center of the needle bed where the front and rear needle beds face each other. However, since the knitted fabric is sandwiched between needle beds on both sides, it is difficult to deal with changes in the thickness of the knitted fabric. In addition, the front and back knitted fabrics, such as tubular knitted fabrics, are pinched together and remain in the needle opening even when the movable sinker is opened, so the knitted fabric can be caught during racking when the needle bed is moved longitudinally to shift the front and back opposing positions. There is a risk.

本発明の目的は、歯口周辺の編地を下方に押し下げ可能で、ラッキング時に編地を引っ掛けることのない横編機の可動シンカーを提供することである。 An object of the present invention is to provide a movable sinker for a flat knitting machine that is capable of pushing down the knitted fabric around the gap and does not catch the knitted fabric during racking.

本発明は、歯口を挟む前後に少なくとも一対の針床を備え、各針床の長手方向に並設される針溝に収容される編針が歯口に進退して編地を編成し、旧ループの編目のノックオーバーに寄与する歯口ワイヤーを各針床の歯口側で長手方向に貫通するように支持する横編機で、

Further, in the present invention, the arc portion approaches the tooth gap wire at an interval smaller than the diameter of the tooth gap wire.
It is characterized by

本発明によれば、可動シンカーは、針溝の側壁に設けられる揺動支承部で支承される揺動で、揺動支承部から歯口側に延びる作用腕が歯口から退出する方向の開位置と、作用腕が歯口に進入する方向の閉位置との間を、進退可能である。作用腕が延びる方向の先端に有する編地押し下げ部は、開位置から閉位置への突出で、針床から垂れ下がる編地を押し下げ可能であるので、歯口周辺の編地を下方に押し下げることができる。開位置では、編地押し下げ部が編地から離れ、針床側に隠れるので、ラッキング時に編地を引っ掛けるような支障が生じないようにすることができる。 According to the present invention, the movable sinker is oscillated by the oscillating support provided on the side wall of the needle groove, and the working arm extending from the oscillating support toward the tooth gap opens in the direction in which it exits from the tooth gap. It is possible to move back and forth between this position and a closed position in which the working arm enters the tooth gap. The knitted fabric pushing down part provided at the tip in the extending direction of the working arm projects from the open position to the closed position and can push down the knitted fabric hanging down from the needle bed, so it can push down the knitted fabric around the needle bed opening. can. In the open position, the knitted fabric push-down part is separated from the knitted fabric and hidden on the needle bed side, so that problems such as the knitted fabric being caught during racking can be prevented.

また本発明によれば、編地押し下げ部は、平坦な形状を有するので、開位置から閉位置に揺動して編地を押し下げる際に突き刺さったり引っ掛かったりしないし、閉位置から開位置に揺動すると編地を円滑に解放することができる。 Further, according to the present invention, since the knitted fabric pushing down part has a flat shape, it does not pierce or get caught when swinging from the open position to the closed position and pushing down the knitted fabric, and it does not pierce or catch when swinging from the open position to the open position. By moving the knitted fabric, the knitted fabric can be released smoothly.

また本発明によれば、編地押し下げ部の歯口側先端は開位置側に折れ曲がり、揺動の支点からの距離が一定で歯口に臨む円弧部に続くので、円弧部には編地が引っ掛かることなく円滑に作用腕を開閉することができる。 Further, according to the present invention, the tip of the knitted fabric push-down portion on the side of the stitch gap is bent toward the open position side, and continues to the circular arc portion facing the stitch gap with a constant distance from the swinging fulcrum, so that the knitted fabric is not attached to the circular arc portion. The operating arm can be opened and closed smoothly without getting caught.

また本発明によれば、開位置で、四枚ベッド機の上段の編針のフックが通過する位置に凹部が設けられるので、フックが編糸を引き込んでループを形成する際に支障が出ないようにすることができる。 Further, according to the present invention, a recess is provided at a position where the hook of the knitting needle in the upper row of the four-bed machine passes through in the open position, so that there is no problem when the hook draws in the knitting yarn to form a loop. It can be done.

また本発明によれば、ループ押し下げ部は閉位置で、編目が歯口で浮かないように押えることができる。 Further, according to the present invention, when the loop pressing down portion is in the closed position, it is possible to press the stitches so that they do not float at the gap.

また本発明によれば、編地押し下げ部を歯口ワイヤーの直下に出没させて、編地を有効に引き下げることができる。 Further, according to the present invention, the knitted fabric can be effectively pulled down by making the knitted fabric push-down portion appear and retract directly below the gap wire.

Corresponding parts in each figure are indicated by the same reference numerals, and overlapping explanations may be omitted. Furthermore, for convenience of explanation, parts that are not shown in the figure to be explained may be referred to using reference numerals that appear in other figures.

図1は、本発明の実施例1である可動シンカー1の部品としての正面構成を示す。可動シンカー1は、鉄鋼などの金属板製であり、作用腕の先端側を除いて、基本的に特許文献1の可動シンカーと同様である。可動シンカー1は、揺動支承部2から作用腕3と駆動腕4とが異なる方向に延びて、ばね5も一体化されており、揺動支承部2の円周の中心を支点2aとして揺動する。作用腕3の先端部分は、ループ押し込み部3a、付き上がり防止部3b、編地押し下げ部3c、円弧部3dおよび凹部3eを有する。駆動腕4は、先端に駆動受け部4aを有する。ループ押し込み部3aは、特許文献1の編糸受け部に対応する。可動シンカー1では、支点2aから駆動腕4の駆動受け部4aまでの半径となる距離よりも作用腕3の先端部分までの距離が大きくなるので、駆動腕4を駆動するストロークよりも、作用腕3が揺動するストロークを大きくすることができる。編地押し下げ部3cは、直線または曲率半径の大きな曲面であり、平坦な形状を有する。編地押し下げ部3cのうちで、支点2aからの距離が最大となる部分は、ループ押し込み部3a側に折れ曲がる形状となり、支点2aからの距離が一定の円弧部3dに続く。図示の編地押し下げ部3cと円弧部3dとは、70度程度の角度をなしている。この角度は、予め設定される範囲、たとえば45度から135度の範囲とし、あまり小さい角度とならないようにする。 FIG. 1 shows the front configuration of a movable sinker 1 as a part, which is Embodiment 1 of the present invention. The movable sinker 1 is made of a metal plate such as steel, and is basically the same as the movable sinker of Patent Document 1 except for the tip side of the working arm. The movable sinker 1 has a working arm 3 and a driving arm 4 extending in different directions from a swinging support 2, a spring 5 is also integrated, and the movable sinker 1 swings with the center of the circumference of the swinging support 2 as a fulcrum 2a. move. The distal end portion of the working arm 3 has a loop push-in portion 3a, a sticking prevention portion 3b, a knitted fabric push-down portion 3c, an arcuate portion 3d, and a recess portion 3e. The drive arm 4 has a drive receiving portion 4a at its tip. The loop pushing part 3a corresponds to the knitting yarn receiving part of Patent Document 1. In the movable sinker 1, since the distance from the fulcrum 2a to the tip of the working arm 3 is larger than the radius from the fulcrum 2a to the drive receiving portion 4a of the driving arm 4, the stroke for driving the driving arm 4 3 can make the swinging stroke larger. The knitted fabric push-down portion 3c is a straight line or a curved surface with a large radius of curvature, and has a flat shape. Of the knitted fabric push-down portions 3c, the portion having the maximum distance from the fulcrum 2a has a shape bent toward the loop push-down portion 3a, and continues to an arcuate portion 3d having a constant distance from the fulcrum 2a. The illustrated knitted fabric push-down portion 3c and the circular arc portion 3d form an angle of about 70 degrees. This angle is set in a preset range, for example, from 45 degrees to 135 degrees, and should not be too small.

図2は、図1の可動シンカー1を含む横編機10の前後の針床11,11が歯口13を挟んで対向している構成を示す。前後の針床11,11は、歯口中央13aに関して、たとえば左が前で右が後となって対称となる。本実施例の横編機10は、前後の針床11,11をそれぞれ上下二段に備える四枚ベッド機である点で、前後の針床が一段ずつの二枚ベッド機である特許文献1の横編機とは異なる。しかしながら、可動シンカー1の揺動に関する構成や動作は、特許文献1と同等である。前後の各針床11は、下段側のみ示す基板12や、固定シンカー14、および図示を省略しているニードルプレート等を含む。ニードルプレートは、図の奥行き方向となる長手方向に一定間隔で立設され、ニードルプレート間に針溝が形成される。可動シンカー1は、作用腕3が歯口側に延びるように、揺動支承部2が針溝の側壁となっているニードルプレートで、針床11の先端側から離れる方向に間隔を空ける位置で支承される。可動シンカー1の作用腕3は、先端が歯口13に進退するように揺動する。図示の可動シンカー1は、作用腕3が歯口13から退出する方向の開位置にあるけれども、作用腕3が歯口13に進入する方向の閉位置に揺動することも可能である。針溝の側壁で支承される揺動支承部2は、揺動の中心となる支点2aを針溝の底部よりも浮いた位置に設けることができる。駆動腕4の先端の駆動受け部4aは、針溝内で、シンカージャックから駆動を受ける。 FIG. 2 shows a configuration in which front and rear needle beds 11, 11 of the flat knitting machine 10 including the movable sinker 1 shown in FIG. 1 face each other with a needle gap 13 in between. The front and rear needle beds 11, 11 are symmetrical with respect to the needle bed center 13a, with the left being the front and the right being the rear, for example. The flat knitting machine 10 of this embodiment is a four-bed machine with front and rear needle beds 11, 11 arranged in upper and lower two stages, respectively, in that it is a two-bed machine with front and rear needle beds in each row.Patent Document 1 It is different from the flat knitting machine. However, the configuration and operation regarding the swinging of the movable sinker 1 are equivalent to those in Patent Document 1. Each of the front and rear needle beds 11 includes a substrate 12 shown only on the lower side, a fixed sinker 14, and a needle plate (not shown). The needle plates are erected at regular intervals in the longitudinal direction, which is the depth direction in the figure, and needle grooves are formed between the needle plates. The movable sinker 1 is a needle plate in which the swing bearing part 2 serves as a side wall of the needle groove, and is located at a position spaced apart from the distal end side of the needle bed 11 so that the working arm 3 extends toward the tooth opening side. Supported. The working arm 3 of the movable sinker 1 swings so that its tip moves forward and backward into the tooth gap 13. Although the illustrated movable sinker 1 is in an open position in which the working arm 3 exits from the tooth gap 13, it can also swing to a closed position in which the working arm 3 enters the tooth gap 13. The swing support portion 2 supported by the side wall of the needle groove can have a fulcrum 2a, which is the center of the swing, at a position higher than the bottom of the needle groove. The drive receiving portion 4a at the tip of the drive arm 4 receives drive from the sinker jack within the needle groove.

ニードルプレートの歯口13に臨む先端側には、固定シンカー14が取付けられる。固定シンカー14は、取付け状態で歯口13に臨む側縁に度決め部14aを有する。度決め部14aは、編目形成時にシンカーループが掛かる。固定シンカー14は、度決め部14aよりも下方に設けられる支持部14bも有する。支持部14bは、歯口ワイヤー15を支持するための孔を有する。この孔を針床11の長手方向に貫通する歯口ワイヤー15は、編目形成時に旧ループの編目のノックオーバーに寄与する。固定シンカー14の基板12への取付けは、取付けワイヤー14cと図示の範囲外となる底部の取付けワイヤーとを用いて行われる。可動シンカー1の円弧部3dは、支点2aからの距離が歯口ワイヤー15までの距離よりも小さい一定の距離で歯口13に臨み、歯口ワイヤー15に、歯口ワイヤー15の直径よりも小さい間隔を空けて接近する。 A fixed sinker 14 is attached to the tip end side of the needle plate facing the needle gap 13. The fixed sinker 14 has a measuring portion 14a on the side edge facing the tooth gap 13 in the attached state. A sinker loop is applied to the degree determining portion 14a during stitch formation. The fixed sinker 14 also has a support portion 14b provided below the degree determining portion 14a. The support portion 14b has a hole for supporting the tooth gap wire 15. The gap wire 15 passing through this hole in the longitudinal direction of the needle bed 11 contributes to knocking over the stitches of the old loop during stitch formation. Attachment of fixed sinker 14 to substrate 12 is performed using attachment wire 14c and a bottom attachment wire outside the range shown. The arc portion 3d of the movable sinker 1 faces the tooth gap 13 at a constant distance from the fulcrum 2a that is smaller than the distance to the tooth gap wire 15, and is attached to the tooth gap wire 15 with a diameter smaller than the diameter of the gap wire 15.

各針床11の上下二段に形成される針溝には、編針として複合針16が収容される。複合針16は、歯口13側の先端にフック16aを有する針本体が針溝内で摺動して歯口13に進退する。複合針16は、フック16aの開閉をスライダー16bで行う。スライダー16bは、針本体に設けるスライダー溝に収容され、針本体に対して摺動して、歯口13側の先端でフック16aを開閉する。新たな編目の形成時には、フック16aがスライダー16bから離れて歯口13に進入し、歯口13で供給される編糸を捕捉して歯口13から退出する。可動シンカー1の作用腕3の先端部分でループ押し込み部3aと円弧部3dとの角には、凹部3eが設けられる。凹部3eは、図示のような可動シンカー1の開位置で、上段の複合針16のフック16aが通過する軌跡に対応する位置となり、フック16aが編糸を引き込む際に、フック16aから固定シンカー14の度決め部14aに渡る編糸と干渉しないための逃がしになっている。編地押し下げ部3cと円弧部3dとが折れ曲がる角部は、作用腕3の歯口13側の先端となる。この角部は、図2のような開位置で、歯口13に突出しないで針床11側に没入して隠れる。このように側面視において可動シンカー1の作用腕3の先端が針床11側に隠れるので、前後の針床11,11間でラッキングが行われても、編目を引っ掛けるような支障は生じない。 Composite needles 16 are accommodated as knitting needles in needle grooves formed in two upper and lower stages of each needle bed 11. The compound needle 16 has a needle main body having a hook 16a at the tip on the needle gap 13 side, and slides within the needle groove to advance and retreat toward the needle gap 13. The compound needle 16 opens and closes the hook 16a using a slider 16b. The slider 16b is accommodated in a slider groove provided in the needle body, slides on the needle body, and opens and closes the hook 16a at the tip on the tooth gap 13 side. When forming a new stitch, the hook 16a moves away from the slider 16b and enters the stitch gap 13, captures the knitting yarn supplied at the stitch gap 13, and exits from the stitch gap 13. At the tip of the working arm 3 of the movable sinker 1, a recess 3e is provided at the corner of the loop push-in portion 3a and the arcuate portion 3d. When the movable sinker 1 is in the open position as shown in the figure, the recess 3e is in a position corresponding to the locus that the hook 16a of the upper compound needle 16 passes, and when the hook 16a pulls in the knitting yarn, the recess 3e moves from the hook 16a to the fixed sinker 14. This is a relief to prevent interference with the knitting yarn passing over the stitching part 14a. The corner portion where the knitted fabric push-down portion 3c and the circular arc portion 3d are bent becomes the tip of the working arm 3 on the side of the tooth opening 13. In the open position as shown in FIG. 2, this corner does not protrude into the needle bed gap 13 but is recessed into the needle bed 11 side and hidden. In this way, since the tip of the working arm 3 of the movable sinker 1 is hidden behind the needle bed 11 side when viewed from the side, even if racking is performed between the front and rear needle beds 11, 11, problems such as catching stitches do not occur.

図3は、横編機10で、可動シンカー1が閉位置にある状態での針床11の歯口13付近の構成を示す。前後の針床11,11で同様の構成を有するので、前の針床11のみ示して重複する説明を省略する。閉位置では、ループ押し込み部3aが歯口ワイヤー15に接近する。ループ押し込み部3aは、揺動の支点2aからの距離が歯口ワイヤー15の位置までの距離よりも大きくて歯口に臨む位置に設けられる。編地押し下げ部3cと円弧部3dとが折れ曲がる角部は、歯口ワイヤー15の下方から歯口13側に突出する。ループ押し込み部3aは、フック16aが編糸を引き込んで形成するニードルループとともに新たに形成されるシンカーループを歯口ワイヤー15付近に押し込む機能を有する。円弧部3dは、歯口ワイヤー15から下方に離れ、開位置側の端部で支点2aからの距離が減少して凹部3eに続く。なお、付き上がり防止部3bは、可動シンカー1の閉位置で機能する。対向する針床11から歯口13に進入する複合針16のフック16aとともに付き上がる編目は、ステッチプレッサーを使用する場合なら押えられると期待されるけれども、押えきれなくて歯口13で浮いたり盛り上がったりする編目が生じる可能性がある。付き上がり防止部3bは、下段の複合針16が歯口13に進退する針底線16c付近で、そのような編目を押える壁として機能する。 FIG. 3 shows the configuration of the needle bed 11 near the needle gap 13 in the flat knitting machine 10 when the movable sinker 1 is in the closed position. Since the front and rear needle beds 11, 11 have the same configuration, only the front needle bed 11 will be shown and redundant explanation will be omitted. In the closed position, the loop push-in portion 3a approaches the gap wire 15. The loop pushing part 3a is provided at a position where the distance from the swinging fulcrum 2a is greater than the distance to the position of the tooth gap wire 15 and faces the tooth gap. The corner portion where the knitted fabric push-down portion 3c and the circular arc portion 3d are bent projects from below the gap wire 15 toward the gap 13 side. The loop pushing part 3a has a function of pushing a newly formed sinker loop into the vicinity of the gap wire 15 together with the needle loop formed by the hook 16a pulling in the knitting yarn. The arcuate portion 3d separates downward from the gap wire 15, continues to the recessed portion 3e with a reduced distance from the fulcrum 2a at the end on the open position side. Note that the sticking prevention part 3b functions when the movable sinker 1 is in the closed position. If a stitch presser is used, the stitches that stick up with the hook 16a of the compound needle 16 entering the needle bed 11 from the opposing needle bed 11 into the needle gap 13 are expected to be pressed down, but if the stitch presser is not used, the stitches may float or bulge at the needle gap 13. There is a possibility that stitches may occur. The sticking prevention portion 3b functions as a wall that suppresses such a stitch near the needle bottom line 16c where the lower compound needle 16 moves forward and backward into the needle gap 13.

図4は、図1の可動シンカー1が編地24を引き下げる状態を模式的に示す。複合針16は、下段のみ示し、上段は図示を省略する。可動シンカー1は、開位置から閉位置に揺動する途中を示す。複合針16のフック16aは、一旦歯口13に進出して、給糸される編糸を捕捉して引き込むことで、新ループ20を形成する。新ループ20は、固定シンカー14の度決め部14aに掛かるシンカーループ21と、フック16aに引き込まれて形成されるニードルループ22とで形成される。編目形成を連続して行っている場合、フック16aに形成されていたニードルループ22は、フック16aが歯口13に進出する前進に対し、フック16aから離れて針本体の針幹に後退してクリアされて旧ループ23となる。針本体の前進に対し、スライダー16bは、相対的に後退してフック16aを開きながらスライダー溝に沈むので、旧ループ23のクリアが可能となる。進出した歯口13で給糸を受けたフック16aが引き込まれると、スライダー16bは相対的に前進してフック16aを閉じ、旧ループ23はフック16aを閉じているスライダー16bを乗り越えてノックオーバーされる。ノックオーバーされた旧ループ23は、歯口ワイヤー15を越えて針床11に近い位置で歯口13の下方に垂れ下がる編地24に続く。 FIG. 4 schematically shows a state in which the movable sinker 1 of FIG. 1 pulls down the knitted fabric 24. Only the lower stage of the compound needle 16 is shown, and the illustration of the upper stage is omitted. The movable sinker 1 is shown in the middle of swinging from the open position to the closed position. The hook 16a of the compound needle 16 once advances to the needle gap 13, captures and draws in the fed knitting yarn, thereby forming a new loop 20. The new loop 20 is formed by a sinker loop 21 that hangs over the measuring part 14a of the fixed sinker 14, and a needle loop 22 that is formed by being drawn into the hook 16a. When stitch formation is being performed continuously, the needle loop 22 formed on the hook 16a moves away from the hook 16a and retreats to the needle stem of the needle body as the hook 16a moves forward toward the needle gap 13. It is cleared and becomes the old loop 23. As the needle body moves forward, the slider 16b moves relatively backward and sinks into the slider groove while opening the hook 16a, so that the old loop 23 can be cleared. When the hook 16a, which has received yarn feeding at the advanced splint gap 13, is pulled in, the slider 16b moves relatively forward and closes the hook 16a, and the old loop 23 climbs over the slider 16b that closes the hook 16a and is knocked over. Ru. The knocked-over old loop 23 continues to the knitted fabric 24 which crosses the needle bed gap wire 15 and hangs below the needle bed gap 13 at a position close to the needle bed 11.

歯口ワイヤー15の下方で歯口13側に突出する編地押し下げ部3cは、可動シンカー1が開位置から閉位置に時計回り方向に揺動すると、歯口13の中央ではなく、針床に近い位置で編地24を下方に押し下げることができる。閉位置から開位置への揺動では、反時計回り方向となるので、編地押し下げ部3cは円滑に編地24から離れ、押し下げを解除して編地24を解放することができる。編地押し下げ部3c、円弧部3dおよびその角部は、平坦であり、鈎状等の突起や凹凸が無くて編地24に引っ掛かることはない。編地押し下げ部3cは、編地24に引っ掛かる部分が無いため、編地24を確実に捕捉して保持できるように幅を持たせている。 When the movable sinker 1 swings clockwise from the open position to the closed position, the knitted fabric push-down part 3c that protrudes toward the needle bed gap 13 below the needle gap wire 15 is located not in the center of the needle bed gap 13 but in the needle bed. The knitted fabric 24 can be pushed down at a close position. Since the swinging from the closed position to the open position is in a counterclockwise direction, the knitted fabric pushing down portion 3c can smoothly move away from the knitted fabric 24, release the pushing down, and release the knitted fabric 24. The knitted fabric push-down part 3c, the arcuate part 3d, and the corners thereof are flat and do not have hook-shaped protrusions or irregularities, so that they do not get caught on the knitted fabric 24. Since the knitted fabric push-down part 3c has no part to catch on the knitted fabric 24, it has a width so that the knitted fabric 24 can be reliably captured and held.

以上のように、編地押し下げ部3cを可動シンカー1に備えることによって、前後の針床11,11で別々に編成して筒状に繋げるような編地を、効果的に押し下げることができる。特にピンタックや引き返し編みなどの難編成組織で、編地下がりを改善し、編成を容易にすることができる。ポケットなどの編成も容易となり、筒状編地での柄や形状の幅を広げることができる。 As described above, by providing the movable sinker 1 with the knitted fabric pushing down part 3c, it is possible to effectively push down the knitted fabric that is knitted separately with the front and rear needle beds 11, 11 and connected into a tubular shape. Particularly in difficult-to-knit structures such as pin tucks and flechage knitting, it is possible to improve knitted fabric fall and make knitting easier. It is also easier to knit pockets, etc., and the range of patterns and shapes of tubular knitted fabrics can be expanded.

なお、本実施例の横編機10は四枚ベッド機であるけれども、特許文献1と同様な二枚ベッド機にも本発明を同様に適用することができる。また、可動シンカー1にはばね5が一体化されているけれども、別体のばねを用いたり、ばねの付勢を行わないようにしたりすることもできる。可動シンカー1の揺動は、特許文献1のように針溝内で駆動腕4の駆動受け部4aをシンカージャックで駆動して、シンカー装置としての嵩が高くならないように行っているけれども、駆動用のバットを針溝外に突出させて、カムで直接駆動するようにしてもよい。編針として複合針16を使用しているけれども、べら針を使用することもできる。 Although the flat knitting machine 10 of this embodiment is a four-bed machine, the present invention can be similarly applied to a two-bed machine similar to Patent Document 1. Further, although the spring 5 is integrated into the movable sinker 1, a separate spring may be used or the spring may not be biased. Although the movable sinker 1 is oscillated by driving the drive receiving part 4a of the drive arm 4 in the needle groove with a sinker jack as in Patent Document 1, so as not to increase the bulk of the sinker device, The butt for use may protrude outside the needle groove and be directly driven by a cam. Although compound needles 16 are used as knitting needles, latch needles may also be used.

図5は、本発明の実施例2である可動シンカー31の部品としての正面構成を示す。可動シンカー31は、作用腕33の先端側を除いて、基本的に図1の可動シンカー1と同様である。すなわち、可動シンカー31の揺動支承部32、作用腕33、駆動腕34、ばね35、支点32a、ループ押し込み部33a、編地押し下げ部33c、円弧部33d、凹部33e、および駆動受け部34aは、可動シンカー1の各部に対応する。ただし、可動シンカー1の付き上がり防止部3bに対して、ループ押下げ部33bを設ける。ループ押下げ部33bは、付き上がり防止部3bを設ける場合よりも、可動シンカー31の閉位置で、針底線16cを越えて下方側に膨らむ形状を有する。ループ押し下げ部33bは、付き上がり防止の壁としても機能する。 FIG. 5 shows a front configuration of a movable sinker 31 as a component according to a second embodiment of the present invention. The movable sinker 31 is basically the same as the movable sinker 1 in FIG. 1 except for the distal end side of the working arm 33. That is, the swing support part 32, the working arm 33, the drive arm 34, the spring 35, the fulcrum 32a, the loop push-in part 33a, the knitted fabric push-down part 33c, the circular arc part 33d, the recess 33e, and the drive receiving part 34a of the movable sinker 31 are as follows. , corresponding to each part of the movable sinker 1. However, a loop pressing down part 33b is provided for the sticking prevention part 3b of the movable sinker 1. The loop push-down portion 33b has a shape that swells downward beyond the needle bottom line 16c when the movable sinker 31 is in the closed position, compared to when the sticking prevention portion 3b is provided. The loop push-down portion 33b also functions as a wall to prevent the loop from sticking up.

図6は、図3の可動シンカー1を図5の可動シンカー31で置き換えた歯口13付近の構成を示す。図示のような可動シンカー31の閉位置にある状態では、ループ押し下げ部33bが膨らむ先端は、針底線16cを越えて下方まで歯口13に進入する。歯口13に進入するループ押し下げ部33bは、ピンタックや引き返し編成などの難編成組織の編地に対し、ループ押し込み部33aや編地押し下げ部33bが機能して押し下げても、押し下げ切れない分を、押さえることができる。ループ押し下げ部33bが膨らむ先端は、閉位置で歯口中央13aまでにする。ただし、歯口13では、編地を押えるためのステッチプレッサーが使用される場合がある。そのような場合、ループ押し下げ部33bが膨らむ先端は、ステッチプレッサーが通る歯口中央13aを避けて、針床11側に寄る位置までにしておく。 FIG. 6 shows a configuration near the tooth gap 13 in which the movable sinker 1 in FIG. 3 is replaced with the movable sinker 31 in FIG. 5. When the movable sinker 31 is in the closed position as shown in the figure, the swollen tip of the loop push-down portion 33b enters the needle gap 13 downward beyond the needle bottom line 16c. The loop push-down section 33b that enters the stitch gap 13 is capable of pushing down the knitted fabric with difficult-to-knit structures such as pin tuck and flechage knitting even if the loop push-down section 33a and the knitted fabric push-down section 33b function to push it down. , can be held down. The swollen tip of the loop push-down portion 33b reaches the center of the tooth opening 13a in the closed position. However, in the stitch gap 13, a stitch presser may be used to press the knitted fabric. In such a case, the swollen tip of the loop push-down portion 33b is placed at a position close to the needle bed 11 side, avoiding the needle mouth center 13a through which the stitch presser passes.
