Description

本発明は、横編機の針床の歯口側先端に設ける固定シンカー、およびそのような固定シンカーを備える横編機に関する。 The present invention relates to a fixed sinker provided at the tip of a needle bed of a flat knitting machine on the needle bed side, and a flat knitting machine provided with such a fixed sinker.

従来から、横編機は、針床の長手方向に一定のピッチで並設される編針を有する。針床は、少なくとも二つが歯口の前後に対向するように配置される。各編針は、針床に設ける針溝に収容され、先端に設けるフックが歯口に進退するように駆動される。針床が歯口に臨む先端側の編針間には、独立した部材として板状のシンカーが配置される。編針の駆動は、先端のフックを歯口に進出させ、歯口上方からフックに編糸を供給してから、フックを針床に引込むように行う。シンカーは、編針を針床に引込む際に、フックで形成するニードルループとともにシンカーループを形成して、編目の大きさを決定する度決めを行うために使用される。針床の歯口側に装着されて不動の固定シンカーは、度決めの基本機能を有するとともに、固定シンカーの側面に突起を設ければ、編針の側方荷重に対する支持を行う機能を付加することもできる(たとえば、特許文献1参照)。 Conventionally, a flat knitting machine has knitting needles arranged side by side at a constant pitch in the longitudinal direction of a needle bed. The needle beds are arranged such that at least two of them are opposed to each other in front and behind the denture. Each knitting needle is housed in a needle groove provided in a needle bed, and driven such that a hook provided at its tip advances and retreats from a needle bed. A plate-shaped sinker is arranged as an independent member between the knitting needles on the tip side of the needle bed facing the needle bed. The knitting needle is driven by advancing the hook at the tip into the needle bed, supplying knitting yarn to the hook from above the needle bed, and then pulling the hook into the needle bed. The sinker is used to form a sinker loop together with a needle loop formed by a hook when pulling the knitting needle into the needle bed, and to determine the size of the stitch. A fixed sinker attached to the needle bed side and immovable has a basic function of determining the degree, and if a projection is provided on the side surface of the fixed sinker, a function of supporting the side load of the knitting needle is added. (See, for example, Patent Document 1).

度決め機能を有するシンカーとしては、歯口側の先端部分が揺動する可動シンカーも用いられる。可動シンカーの揺動する先端部分は、形成された編目を歯口下方に押込む機能を有する。可動シンカーと固定シンカーとを併用し、度決めを固定シンカーで行わせることもできる(たとえば特許文献2参照)。固定シンカーは、歯口側先端付近に設ける孔で天歯となる線材を支持し、新たな編目を形成する際に、旧編目のノックオーバーを安定させることもできる。 As a sinker having a degree setting function, a movable sinker whose tip part on the side of the tooth mouth oscillates is also used. The oscillating tip portion of the movable sinker has a function of pushing the formed stitch downwardly. A movable sinker and a fixed sinker can be used together, and the degree of strength can be determined by the fixed sinker (see Patent Document 2, for example). The fixed sinker can also support the wire that will be the crown tooth in the hole provided near the tip of the tooth mouth side, and stabilize the knockover of the old stitch when forming a new stitch.

特許文献2の横編機には、後針床の上方に設ける補助床から、前後の針床の固定シンカーと編針との間に進退するループプレッサーも設けられる。ループプレッサーは、編糸を編針のフックに案内したり、編成される編目を押えたりする機能を有する(たとえば特許文献3参照)。 The flat knitting machine of Patent Document 2 is also provided with a loop presser that advances and retreats between the fixed sinkers and the knitting needles of the front and rear needle beds from an auxiliary bed provided above the rear needle bed. The loop presser has the function of guiding the knitting yarn to the hook of the knitting needle and pressing the stitch to be knitted (see, for example, Patent Document 3).

特許文献3のように、前後の両針床に設ける編針および固定シンカーとともに、一針床、たとえば後針床の上方に設けて併用されるループプレッサーは、良好な編目の形成を可能にする編成部材の一つであると考えられる。編成部材の機能は、種々考えられるけれども、前針床に対しては、歯口を挟んで対向する針床の上方から歯口に進出し、歯口で下降しながら固定シンカーの側面まで到達して機能を果す必要がある。各針床には、多くの編針が狭い隙間をあけて配設されるので、編成部材は、編針間の中央となる固定シンカーと編針との間の狭い隙間に侵入する必要がある。編成部材が対向する針床の上方から固定シンカーと編針との隙間に侵入する場合には、前後の針床間でのずれの影響も加わり、編成部材と固定シンカーとが衝突する可能性が生じる。このような編成部材の進退で、編成部材と固定シンカーとが衝突すると、固定シンカーや編成部材が変形したり、破損したりするおそれがある。 As in Patent Document 3, a loop presser provided above one needle bed, for example, the back needle bed and used together with knitting needles and fixed sinkers provided on both the front and back needle beds enables formation of good stitches. It is considered to be one of the members. Various functions of the knitting member are conceivable, but with respect to the front needle bed, it advances from above the needle bed facing the front needle bed, descends at the needle bed, and reaches the side of the fixed sinker. function. Since a large number of knitting needles are arranged on each needle bed with narrow gaps, the knitting member needs to enter the narrow gap between the knitting needles and the fixed sinker, which is the center between the knitting needles. When the knitting member enters the gap between the fixed sinker and the knitting needle from above the opposing needle beds, the influence of the displacement between the front and back needle beds is also added, and there is a possibility that the knitting member and the fixed sinker collide. . If the knitting member collides with the fixed sinker due to the advance and retreat of the knitting member, the fixed sinker and the knitting member may be deformed or damaged.

横編機では、細い編糸を使用して細かい編目の編地を編成するために、編針を並設するピッチを細かくすることが要望されている。ピッチが細かくなると、編成部材を侵入させる固定シンカーと編針との間の隙間も狭くなり、前後の針床間のずれの許容範囲も狭くなって、前後の対向位置の調整が難しくなる。編成部材と固定シンカーとの衝突を避けるためには、編成部材や固定シンカーの板厚を薄くすることも考えられる。しかしながら、板厚を薄くすると、編成部材や固定シンカーは曲がりやすくなり、細くなった編糸は掛かって切れやすくなってしまう。 In a flat knitting machine, it is desired to reduce the pitch at which knitting needles are arranged side by side in order to knit a knitted fabric with fine stitches using fine knitting yarn. As the pitch becomes finer, the gap between the fixed sinker into which the knitting member enters and the knitting needle becomes narrower, and the allowable range of deviation between the front and rear needle beds becomes narrower, making it difficult to adjust the front and rear opposing positions. In order to avoid collision between the knitting member and the fixed sinker, it is conceivable to reduce the plate thickness of the knitting member and the fixed sinker. However, when the board thickness is reduced, the knitting member and the fixed sinker tend to bend, and the thin knitting yarn is easily caught and cut.

本発明の目的は、固定シンカーと編成部材とが衝突し難くなる固定シンカーおよび横編機を提供することである。 SUMMARY OF THE INVENTION An object of the present invention is to provide a fixed sinker and a flat knitting machine in which the fixed sinker and the knitting member are less likely to collide with each other.

本発明は、歯口を挟んで対向する少なくとも一対の針床を有する横編機で、針床に並ぶ編針間の歯口側先端に配置され、シンカーループ形成の機能を有する板状のシンカー本体を含む、横編機の固定シンカーにおいて、

It is a fixed sinker characterized by having it above the .

Further, the sinker body of the present invention is characterized in that the thickness is also inclined on the other side surface which is the back side of the one side surface.

In the present invention, both side surfaces of the one side surface and the other side surface of the sinker body are provided with support projections projecting toward the side surface of the knitting needle extending into the needle gap,
The slope of the thickness is provided on both side surfaces of the portion excluding the support protrusion.

歯口を挟んで対向する少なくとも一対の針床と、
歯口への進退、および歯口での上下動を行う編成部材と

The present invention also provides a fixed sinker characterized by any of the above items,
at least a pair of needle beds facing each other across the tooth gap;
A knitting member that advances and retreats to the tooth gap and moves up and down at the tooth gap,
The plate-shaped sinker body of the fixed sinker is arranged at the tip of at least one needle bed on the tooth mouth side,
The knitting member is provided above at least the other needle bed in the flat knitting machine.

本発明によれば、固定シンカーは板状のシンカー本体を含む。シンカー本体は、横編機の針床の歯口側先端に配置され、少なくとも一側面では、上方の始端から下方の終端に向う変化方向に沿って厚さが増加する。対向する針床側から歯口に進出する編成部材は、シンカー本体の一側面と隣接する編針のフックとの間の隙間を、一側面の厚さの変化方向に沿って下降する状態となる。編成部材の隙間への下降が開始される上方の始端でシンカー本体の厚さが下方の終端に比べて薄くなるので、衝突し難くすることができる。シンカー本体は、変化方向に沿う傾斜で終端に向って厚さが増加するので、全体を始端の薄さにする場合に比較して、曲がり難くすることができる。
また、シンカー本体の前縁は、上方の始端で厚さが薄くなっても、編目形成の際にシンカーループが掛かる度決め部は始端から終端までの中間付近になるので、編糸が掛かる部分の厚さが薄くならないようにすることができる。
According to the invention, the stationary sinker comprises a plate-shaped sinker body. The sinker body is arranged at the tip of the needle bed of the flat knitting machine on the needle bed side, and on at least one side surface, the thickness increases along the changing direction from the upper start end to the lower end end. The knitting member advancing from the opposing needle bed side to the needle bed descends along the thickness change direction of the one side in the gap between the one side of the sinker body and the hook of the adjacent knitting needle. Since the thickness of the sinker body is thinner at the upper start end where the knitting member starts to descend into the gap than at the lower end end, it is possible to make collision difficult. Since the thickness of the sinker body increases toward the terminal end with an inclination along the direction of change, it is possible to make it difficult to bend compared to the case where the entire sinker body is thinned at the starting end.
In addition, even if the thickness of the front edge of the sinker body becomes thin at the upper starting end, the part where the sinker loop is applied when forming the stitch is near the middle from the starting end to the terminal end, so the portion where the knitting yarn is applied. thickness can be prevented from becoming thin.

また本発明によれば、板状のシンカー本体の他側面も変化方向に沿って上方の始端で薄く下方の終端で厚くなるので、前後に対向する両針床に配置し、部品として共用する場合に、厚さの傾斜を有効に利用することができる。上方に編成部材が設けられる針床側では、歯口に進出して下降する編成部材が通過する他側面の始端が薄くなるので、編成部材とシンカー本体とが衝突し難くすることができる。両方の針床で可動シンカーも併用する場合にも、可動シンカーが揺動する側面を編成部材が通過する側面の裏面側にして、薄くなる始端との隙間を増やして干渉し難くすることができる。 Further, according to the present invention, the other side surface of the plate-like sinker body is also thin at the upper start end along the change direction and becomes thick at the lower end end, so that when the sinker body is arranged on both front and rear facing needle beds and shared as a part. In addition, the thickness gradient can be effectively used. On the needle bed side where the knitting member is provided above, the starting end of the other side surface through which the knitting member descending into the tooth gap passes is thinner, so that the knitting member and the sinker body are less likely to collide. Even when the movable sinker is also used for both needle beds, the side surface on which the movable sinker swings is the back side of the side surface through which the knitting member passes, thereby increasing the gap between the thinning starting end and making it difficult to interfere. .

また本発明によれば、歯口を挟んで対向する針床側から編成部材が進退する針床に配置する場合に、固定シンカーのシンカー本体は、編成部材の先端が支持突起に達するまで厚さが増大する一側面側の傾斜に沿って、編成部材を側方に侵入させることができる。支持突起は、一側面側を進退する編針が、侵入した編成部材に近づき過ぎないように側方を支持することができる。 Further, according to the present invention, when the knitting member is arranged on the needle bed where the knitting member advances and retreats from the needle bed side facing the needle bed across the needle bed, the sinker main body of the fixed sinker has a thickness until the tip of the knitting member reaches the support projection. The knitted member can be laterally intruded along the slope of one side with increasing . The support projection can support the side so that the knitting needle advancing and retreating on the one side does not come too close to the intruding knitting member.

また本発明によれば、少なくとも一方の針床の歯口側先端に固定シンカーのシンカー本体を配置し、対向する他方の針床の上方に設けられる編成部材が歯口に進退し、歯口で上下動を行う際に、編成部材とシンカー本体とが衝突し難い横編機を得ることができる。 Further, according to the present invention, the sinker main body of the fixed sinker is arranged at the tip of at least one needle bed on the needle bed side, and the knitting member provided above the other opposing needle bed advances and retreats to and from the needle bed. It is possible to obtain a flat knitting machine in which the knitting member and the sinker body are less likely to collide when vertically moved.

以下、図1から図4で、本発明の一実施例である固定シンカー1の概略的な構成について説明する。説明の便宜上、説明対象の図には記載されていない部分について、他の図に記載される参照符を付して言及する場合がある。 A schematic configuration of a fixed sinker 1 according to an embodiment of the present invention will be described below with reference to FIGS. 1 to 4. FIG. For convenience of explanation, parts not shown in the figure to be explained may be referred to by attaching reference numerals shown in other figures.

図1は、本発明の一実施例である固定シンカー1の構成を示す。(a)は、固定シンカー1で、シンカーループの形成などの機能を果すシンカー本体2の正面図であり、(b)は針床に装着される姿勢で示す固定シンカー1の全体的な右側面図である。シンカー本体2は、板状であり、横編機の針床の歯口側先端に配置され、シンカーループ形成の機能を有する。シンカー本体2の一側面2aに、針床への配置状態で、上方の始端2fから下方の終端2gに向うように予め定められる変化方向Dに沿って増加するような、厚さについての傾斜が設けられる。シンカー本体2で一側面2aの裏面側となる他側面2bにも、同様な傾斜が設けられる。本実施例では、シンカー本体2の両側面2a,2bで対称となるように厚さが増大する傾斜が設けられて、(a)に示す正面図でシンカー本体2はテーパー状になる。 FIG. 1 shows the configuration of a fixed sinker 1 that is one embodiment of the present invention. (a) is a front view of a sinker main body 2 of the fixed sinker 1 that performs functions such as forming a sinker loop, and (b) is an overall right side view of the fixed sinker 1 shown in the posture of being attached to the needle bed. It is a diagram. The sinker main body 2 is plate-shaped, is arranged at the tip of the needle bed of the flat knitting machine on the needle bed side, and has the function of forming a sinker loop. One side surface 2a of the sinker body 2 has a thickness gradient that increases along a predetermined change direction D from an upper starting end 2f toward a lower terminal end 2g in the state of being placed on the needle bed. be provided. The other side surface 2b of the sinker body 2, which is the back side of the one side surface 2a, is similarly inclined. In this embodiment, both side surfaces 2a and 2b of the sinker body 2 are symmetrically inclined so that the thickness increases, and the sinker body 2 is tapered in the front view shown in (a).

固定シンカー1で、シンカー本体2を除く他の部分は、厚さがシンカー本体2よりも大きくなって、支持突起3および装着アーム4となる。支持突起3は、固定シンカー1としての針床への装着時、歯口に進出する編針が側方荷重を受けて曲がろうとする際に、編針の側面に当って側方への撓みを阻止するように支持する。本実施例では、上下二段の針床を有する横編機に使用し、支持突起3は上段用部分3aおよび下段用部分3bを含む。支持突起3は、固定シンカー1の針床への装着時、シンカー本体2の歯口から離れる側に設けられる。シンカー本体2の歯口側は前縁2cとなり、前縁2cの上下中間付近の凹部は度決め部2dとなる。度決め部2dと終端2gとの中間付近に、貫通孔2eが設けられる。貫通孔2eは、天歯となるワイヤーを支持することができる。シンカー本体2および支持突起3の下部は、装着アーム4に続く。装着アーム4は、上端側に掛止め凹所4a、下端側に貫通孔4bを有する。 In the fixed sinker 1, other parts than the sinker main body 2 are thicker than the sinker main body 2 and become the support projection 3 and the mounting arm 4. - 特許庁When the needle bed as the fixed sinker 1 is attached to the needle bed, the support projection 3 hits the side surface of the knitting needle and prevents the lateral deflection when the knitting needle advancing to the tooth gap is subjected to a side load and tries to bend. support to do so. This embodiment is used in a flat knitting machine having upper and lower two-stage needle beds, and the support protrusion 3 includes an upper stage portion 3a and a lower stage portion 3b. The support projection 3 is provided on the side of the sinker main body 2 away from the needle bed when the fixed sinker 1 is attached to the needle bed. The tooth mouth side of the sinker body 2 becomes the front edge 2c, and the concave portion near the upper and lower middle of the front edge 2c becomes the degree determining portion 2d. A through hole 2e is provided near the middle between the degree determining portion 2d and the terminal end 2g. The through-hole 2e can support a wire that becomes the top tooth. The sinker body 2 and the lower part of the support projection 3 continue to the mounting arm 4 . The mounting arm 4 has a latch recess 4a on the upper end side and a through hole 4b on the lower end side.

(a)に示すように、シンカー本体2の板厚は、上方の始端2fでT1、始端2fから高さHだけ離れる下方の終端2gでT2となる。始端2fから終端2gに向う方向は、(b)に変化方向Dに沿う方向となる。変化方向Dは編成部材の侵入方向に関連し、侵入方向は図3に関する説明で後述する。 As shown in (a), the plate thickness of the sinker body 2 is T1 at the upper starting end 2f, and T2 at the lower terminal end 2g separated by the height H from the starting end 2f. The direction from the start end 2f to the end end 2g is the direction along the change direction D in (b). The direction of change D relates to the direction of entry of the knitted member, which direction will be described later in the description relating to FIG.

固定シンカー1を製造する際には、装着アーム4として必要な板厚の金属板を素材として使用し、支持突起3は板厚を減少させないで残して、シンカー本体2の部分の板厚を減少させるような加工を施す。この加工は、機械的な切削や研削で行うことが可能である。厚さ増大の傾斜は、一側面2aと他側面2bとで角度が異なるような非対称にしたり、角度が途中で変化したり、曲面にしたり、一側面2aのみに設けることもできる。 When manufacturing the fixed sinker 1, a metal plate having a thickness required for the mounting arm 4 is used as a material, and the plate thickness of the sinker main body 2 is reduced while the plate thickness of the support projection 3 is left unchanged. It is processed to make it look like it. This processing can be performed by mechanical cutting or grinding. The inclination of thickness increase may be asymmetric such that the angle is different between one side surface 2a and the other side surface 2b, the angle may change in the middle, the surface may be curved, or only one side surface 2a may be provided.

シンカー本体2の厚さは、加工前の金属板の厚さの4分の1程度となる。金属板としては、たとえば1mm程度の厚さの鋼鉄板を使用することができる。厚さのテーパーは、たとえば始端2fでの厚さT1を0.26mm、終端2gでの厚さT2を0.30mm程度として形成する。高さHは、たとえば8mm程度とする。この場合、8mm進む間に0.04mmの厚さが増大するので、0.5%の傾斜が得られる。始端2fの厚さT1を小さくすれば、対向する針床から侵入する編成部材が衝突し難くなる。厚さT1が薄くなっても、始端2fから終端2gまでの途中に有する度決め部2dでの厚さは、始端2fよりも下方となるので、T1よりも厚くなる。終端2gの厚さT2をあまり薄くしなければ、編糸が掛かる度決め部2sの厚さが薄くならないようにすることができる。ただし、上方の始端2fで厚さT1が薄くなって鋭利になると、編糸が歯口で触れて損傷を受けるおそれが生じる。厚さT1,T2は、素材の金属板の板厚、編成部材が侵入して重複する程度等に応じて適宜決めればよい。 The thickness of the sinker main body 2 is approximately one quarter of the thickness of the metal plate before processing. As the metal plate, for example, a steel plate having a thickness of about 1 mm can be used. The tapered thickness is formed with a thickness T1 of about 0.26 mm at the starting end 2f and a thickness T2 of about 0.30 mm at the terminal end 2g, for example. The height H is, for example, approximately 8 mm. In this case, a 0.5% slope is obtained because the thickness increases by 0.04 mm for every 8 mm step. If the thickness T1 of the starting end 2f is reduced, it becomes difficult for the knitting members entering from the opposing needle beds to collide with each other. Even if the thickness T1 is reduced, the thickness at the degree determining portion 2d between the starting end 2f and the terminal end 2g is lower than the starting end 2f and is therefore thicker than T1. If the thickness T2 of the terminal end 2g is not too thin, it is possible to prevent the thickness of the portion 2s where the knitting yarn is hooked from becoming thin. However, if the thickness T1 becomes thin and sharp at the upper starting end 2f, the knitting yarn may come into contact with the needle bed and be damaged. The thicknesses T1 and T2 may be appropriately determined according to the plate thickness of the metal plate as the material, the extent to which the knitting members invade and overlap, and the like.

図2は、図1の固定シンカー1を装着した横編機10の部分的な構成を簡略化して示す。固定シンカー1は、シンカー本体2が前針床11と後針床12とで、対向する基板11a,12aの先端側に装着されるように、取付けられる。各針床11,12は、それぞれ上下二段ずつ設けられるけれども、上段側の針床は図示を省略する。固定シンカー1の取付けは、基板11a,12aの先端側に形成される溝に、装着アーム4を挿入して行う。装着アーム4の掛止め凹所4aと基板11a,12aとの間には掛止めワイヤー13を挿入し、図示を省略している下方の貫通孔4bには、基板11a,12aに設ける溝を通るワイヤーを貫通させる。前針床11および後針床12に装着された固定シンカー1は、前針床11と後針床12との間の間隙に形成される歯口14を挟んで対向する。 FIG. 2 shows a simplified partial configuration of a flat knitting machine 10 to which the fixed sinker 1 of FIG. 1 is attached. The fixed sinker 1 is mounted so that the sinker main body 2 is mounted on the front needle bed 11 and the rear needle bed 12 on the tip sides of the opposing substrates 11a and 12a. Each of the needle beds 11 and 12 is provided in two upper and lower stages, but the illustration of the upper needle beds is omitted. The fixed sinker 1 is attached by inserting the mounting arm 4 into grooves formed on the tip sides of the substrates 11a and 12a. A hooking wire 13 is inserted between the hooking recess 4a of the mounting arm 4 and the substrates 11a and 12a. pass the wire through. The fixed sinkers 1 attached to the front needle bed 11 and the rear needle bed 12 are opposed to each other with the needle bed 14 formed in the gap between the front needle bed 11 and the rear needle bed 12 interposed therebetween.

前針床11と後針床12とは、図示を省略している上段側を含めて、基本的に同様な構成を有し、上下二段に編針15を備える。編針15は、先端のフック15aを歯口14に進退させるとともに、フック15aの開閉をスライダー15bで行う複合針を使用する。シンカーとして、固定シンカー1に加えて、可動シンカー16も使用する。編目形成時には、固定シンカー1のシンカー本体2に設ける貫通孔2eで支持する天歯用ワイヤー17を利用して、ノックオーバーを安定化させる。 The front needle bed 11 and the rear needle bed 12 have basically the same configuration including the upper side (not shown), and are equipped with knitting needles 15 in two upper and lower stages. As the knitting needle 15, a compound needle is used in which a hook 15a at the tip is advanced and retracted to the needle bed gap 14 and the hook 15a is opened and closed by a slider 15b. As sinkers, in addition to the fixed sinker 1, a movable sinker 16 is also used. At the time of stitch formation, the top tooth wire 17 supported by the through hole 2e provided in the sinker body 2 of the fixed sinker 1 is used to stabilize the knockover.

各針床11,12では、歯口14側に並ぶ固定シンカー1のシンカー本体2に対して、歯口14から離れる側にニードルプレートが並ぶように設けられ、ニードルプレート間に編針15を収容する針溝が形成される。ニードルプレートを歯口14側に延長して、先端にシンカー本体2を形成することもできる。上下二段に針床11,12を設ける場合、上段側の針床は、下段側の針床のニードルプレートの上方への延長上に載る。後針床12の上段側のニードルプレートは、上方へ延長され、ループプレッサー20を収容する補助床を支持する。前針床11に装着される固定シンカー1に対して、後針床12の上方からループプレッサー20の先端部21が、シンカー本体2の一側面2a側で重複するように侵入することができる。実線で示すループプレッサー20は、後針床12の上方で待機している状態を示す。ループプレッサー20は、たとえば特許文献3に開示されているように、図示を省略しているキャリッジに搭載されるカム機構で駆動されて、2点鎖線で示すように、上方で後針床12側から歯口14の中央付近に進出し、固定シンカー1のシンカー本体2に接近する。 In each of the needle beds 11 and 12, needle plates are arranged on the side away from the needle bed 14 with respect to the sinker body 2 of the fixed sinker 1 arranged on the needle bed 14 side, and the knitting needle 15 is accommodated between the needle plates. A needle groove is formed. It is also possible to extend the needle plate toward the tooth gap 14 side and form the sinker body 2 at the tip. When needle beds 11 and 12 are provided in two stages, the upper needle bed is placed on the upper extension of the needle plate of the lower needle bed. A needle plate on the upper side of the rear needle bed 12 extends upward and supports an auxiliary bed that accommodates the loop presser 20 . The tip portion 21 of the loop presser 20 can enter the fixed sinker 1 attached to the front needle bed 11 from above the rear needle bed 12 so as to overlap one side surface 2a of the sinker body 2 . The loop presser 20 indicated by a solid line stands by above the rear needle bed 12 . The loop presser 20 is driven by a cam mechanism mounted on a carriage (not shown) as disclosed, for example, in Japanese Patent Laid-Open No. 2002-200023, and moves upward toward the rear needle bed 12 side as indicated by a chain double-dashed line. , it advances to the vicinity of the center of the tooth gap 14 and approaches the sinker body 2 of the fixed sinker 1.

図3は、図2の横編機10で、図1(b)の変化方向Dに関連するループプレッサー20の動作を示す。図2の2点鎖線で示す先端部21がさらに進出して、前針床11の固定シンカー1のシンカー本体2に掛かるようになる位置で、実線で示すように、先端部21は、シンカー本体2の一側面2a側と編針15のフック15aとの隙間を下降する。したがって、シンカー本体2とループプレッサー20の先端部21との重複部分での侵入方向は、図1(b)に示す上下の変化方向Dに対応する。重複範囲へのループプレッサー20の進出が開始される上方の始端2fでシンカー本体2の厚さが下方の終端2fに比べて薄くなるので、機械的な干渉のおそれが低減され、衝突し難くすることができる。シンカー本体2は、一側面2aの裏面側となる他側面2bにも、厚さについての傾斜を設けることで、他側面2bと編針15のフック15aとの隙間に可動シンカー16を設ける場合に、隙間を増やして干渉し難くすることができる。また、固定シンカー1を後針床12に装着する場合に、ループプレッサー20が通過する他側面2bでも厚さについての傾斜を利用して、隙間を確保することができる。 FIG. 3 shows the operation of the loop presser 20 in the flat knitting machine 10 of FIG. 2 in relation to the change direction D of FIG. 1(b). At a position where the tip portion 21 shown by the two-dot chain line in FIG. 2 and the hook 15a of the knitting needle 15. Therefore, the direction of intrusion at the overlapping portion between the sinker body 2 and the tip portion 21 of the loop presser 20 corresponds to the vertical change direction D shown in FIG. 1(b). Since the thickness of the sinker body 2 is thinner at the upper starting end 2f where the loop presser 20 starts to advance into the overlapping range, compared to the lower terminal end 2f, the risk of mechanical interference is reduced, making collision difficult. be able to. In the sinker body 2, the thickness of the other side surface 2b, which is the back side of the one side surface 2a, is also inclined so that when the movable sinker 16 is provided in the gap between the other side surface 2b and the hook 15a of the knitting needle 15, The gap can be increased to make interference difficult. Further, when the fixed sinker 1 is attached to the rear needle bed 12, the other side surface 2b through which the loop presser 20 passes can be secured by utilizing the inclination of the thickness.

図4は、図2の横編機10での固定シンカー1やループプレッサー20の配置を模式的に示す。図2および図3は、編針15が手前側で固定シンカー1が奥側となる位置から見た断面に相当する。固定シンカー1と編針15との間には、ループプレッサー20の先端部21が進退し、可動シンカー16が配置される。ループプレッサー20の先端部21は、前針床11ではシンカー本体2aの一側面2aと編針15のフック15aとの間の隙間Sに侵入し、後針床12では他側面2bとフック15aとの間に侵入する。また、前針床11ではシンカー本体2の他側面2b側、後針床12ではシンカー本体2の一表面2a側に、可動シンカー16がそれぞれ配置され、先端部分が歯口14で揺動する。揺動する先端部分の側方で、シンカー本体2の側面2a,2bの板厚が減少するので、隙間が確保され、揺動時の干渉を減らすことができる。 FIG. 4 schematically shows the arrangement of the fixed sinker 1 and the loop presser 20 in the flat knitting machine 10 of FIG. 2 and 3 correspond to cross sections viewed from a position where the knitting needle 15 is on the front side and the fixed sinker 1 is on the back side. Between the fixed sinker 1 and the knitting needle 15, the tip portion 21 of the loop presser 20 moves forward and backward, and the movable sinker 16 is arranged. The tip portion 21 of the loop presser 20 enters the gap S between the side surface 2a of the sinker body 2a and the hook 15a of the knitting needle 15 on the front needle bed 11, and between the other side surface 2b and the hook 15a on the back needle bed 12. intrude in between. A movable sinker 16 is arranged on the other side surface 2b side of the sinker body 2 on the front needle bed 11 and on the one surface 2a side of the sinker body 2 on the rear needle bed 12. Since the plate thicknesses of the side surfaces 2a and 2b of the sinker body 2 are reduced on the sides of the swinging tip portion, a clearance is secured and interference during swinging can be reduced.

シンカー本体2の両側面2a,2bには、歯口14に進出する編針15の側面に向けて突出する支持突起3が設けられる。ループプレッサー20は、先端部21が支持突起3に達するまで厚さが増大する一側面2a側の傾斜に沿って側方に侵入させることができる。支持突起3は、一側面2a側を進退する編針15が、侵入したループプレッサー20の先端部21に近づき過ぎないように側方を支持することができる。厚さについての傾斜は、支持突起3を除くシンカー本体2の両側面2a,2bに設けられるので、先端部21が侵入可能な範囲で有効に傾斜を設けることができる。 Both side surfaces 2 a and 2 b of the sinker body 2 are provided with support projections 3 projecting toward the side surface of the knitting needle 15 extending into the needle bed 14 . The loop presser 20 can be laterally intruded along the slope of the one side surface 2a side where the thickness increases until the tip 21 reaches the support projection 3 . The support projection 3 can support the side so that the knitting needle 15 advancing and retreating on the one side 2a side does not come too close to the tip 21 of the loop presser 20 that has entered. Since the thickness is inclined on both side surfaces 2a and 2b of the sinker body 2 except for the support projection 3, the inclination can be effectively provided within a range in which the tip portion 21 can enter.

本実施例では、前針床11と後針床12とを上下二段にしているけれども、両方とも一段、または片方が一段でもよい。なお、対向する針床の上方から侵入するループプレッサー20とシンカー本体2の始端2fとが衝突し難くするためには、侵入する一側面2a側のみに板厚が増大する傾斜を設ければよい。板厚の増大は、傾斜によって連続して行うので、段階的に行うような不連続な段部が生じず、ループプレッサー20が接触するような場合でも、円滑に侵入するように案内することができる。 In this embodiment, the front needle bed 11 and the rear needle bed 12 are arranged in two stages, but both may be one stage, or one may be one stage. In order to prevent collision between the loop presser 20 and the starting end 2f of the sinker body 2, which enter from above the opposing needle bed, it is sufficient to provide an inclination that increases the plate thickness only on the side of the intruding side surface 2a. . Since the plate thickness is increased continuously by the inclination, there is no discontinuous step that occurs in stages, and even when the loop presser 20 comes into contact with the loop presser 20, the loop presser 20 can be guided smoothly. can.

以上で説明した板厚の傾斜を設ける効果は、歯口14を挟む前後の針床の一方の上方のみに設ける補助床からループプレッサー20が侵入する場合ばかりではなく、両方の針床の上方からループプレッサー20をそれぞれ侵入させる場合も有効に得られる。編地の編成に寄与するようなループプレッサー20以外の編成部材が侵入する場合にも得られる。たとえば、本実施例では可動シンカー16で行っている編目を下方に押込む作用を、そのよう編成部材で行うようにしてもよい。また、新たな機能を有する編成部材を追加することもできる。 The above-described effect of providing the plate thickness slope is not limited to the case where the loop presser 20 enters from the auxiliary bed provided only above one of the front and rear needle beds sandwiching the needle bed 14, but also from above both needle beds. It can be effectively obtained even when the loop pressers 20 are inserted respectively. It is also obtained when a knitting member other than the loop presser 20 that contributes to the knitting of the knitted fabric enters. For example, the action of pushing the stitches downward, which is performed by the movable sinker 16 in this embodiment, may be performed by such a knitting member. Also, it is possible to add a knitting member having a new function.
