Abstract

PROBLEM TO BE SOLVED: To provide a flat-knitting machine with a movable sinker that can suppress the variation of the stress amplitude of the torque spring at opening and closing the sinker, even with the movable sinker directly controlling with the sinker cam installed in the carriage.SOLUTION: An energizing cam surface 13a presses a tip 12a of a torque spring 12 having a base end 12b between a supporting portion 11a and an acting arm 11b of a sinker 11 to energize the sinker 11 through the torque spring 12. So, it can be weakened at an opened condition, even though it is strengthened at a closed condition. The stress of the torque spring 12 is not larger at the opened condition than those with the closed condition. Therefore, the flat-knitting machine can be configured such that the variation of the stress amplitude of the torque spring 12 is suppressed at opening and closing the sinker, even with the movable sinker 10 directly controlling with the sinker cam installed in the carriage.

Description

本発明は、編地を押下げることが可能な、可動シンカーを備える横編機に関する。   The present invention relates to a flat knitting machine including a movable sinker capable of pushing down a knitted fabric.

従来から、横編機では編針とともに歯口で編目を形成するシンカーを、キャリッジに搭載されるシンカーカムで直接操作して、開閉可能にしているものが知られている（たとえば特許文献１、２参照）。このような可動式のシンカーは、針床の歯口近傍で揺動変位可能に支持される支承部と、支承部から歯口側に延びる作用腕と、支承部から歯口から離れる側に延びる受動腕とを有する。支承部は、円弧状であり、針床側に設ける円弧状に凹んだ支持部に嵌合し、円弧の中心を仮想的な支点として揺動可能な状態で支持される。可動式のシンカーには、作用腕を基端とするトルクばねも用いられる。トルクばねは、シンカーの支承部よりも内側の支点寄りの空間に収容されて、作用腕を歯口に進入する方向に付勢する。作用腕には編糸受け部が設けられ、編成されて歯口から垂下する編地の編目を下方に押下げる機能を有する。トルクばねの先端は、針床に立設するニードルプレートで支持される。   Conventionally, in a flat knitting machine, a sinker that forms a stitch with a knitting needle together with a knitting needle is directly operated by a sinker cam mounted on a carriage so as to be opened and closed (for example, Patent Documents 1 and 2). reference). Such a movable sinker includes a support portion supported so as to be able to swing and displace in the vicinity of the mouth of the needle bed, an operating arm extending from the support to the mouth side, and extending from the support portion to the side away from the mouth. With a passive arm. The support portion has an arc shape, is fitted into a support portion that is recessed in an arc shape provided on the needle bed side, and is supported in a swingable manner with the center of the arc as a virtual fulcrum. A torque spring having a working arm as a base end is also used for the movable sinker. The torque spring is accommodated in a space near the fulcrum on the inner side of the support portion of the sinker, and urges the working arm in the direction of entering the tooth opening. The working arm is provided with a knitting yarn receiving portion, and has a function of pushing down the stitch of the knitted fabric that is knitted and hangs down from the mouth. The tip of the torque spring is supported by a needle plate standing on the needle bed.

編針を歯口に進出させて、フックに編糸を供給する編目形成時などには、作用腕を歯口から退出させる必要がある。トルクばねの付勢で作用腕を歯口に進入させる閉状態に対し、トルクばねの付勢に抗して、作用腕を歯口から針床側に退出させると開状態となる。シンカーを開状態にするために、針床に沿って走行するキャリッジに、シンカーの受動腕に作用するシンカー制御用の後部カムが、シンカーの支承部よりも歯口から離れる後方の位置に臨むように搭載される。トルクばねは、開状態で最大限に押し縮められて応力が最大となり、閉状態では応力が小さくなる。歯口で下方に押下げる編地が無い無負荷では、作用腕は最大限に歯口に進入し、トルクばねの応力は最小となる。閉状態で大きな押下げ力を得ようとすると、開状態でのトルクばねの応力が大きくなり、ばねとしての限界を超えるおそれがある。   For example, when forming a stitch in which the knitting needle is advanced to the tooth opening and the knitting yarn is supplied to the hook, it is necessary to retract the working arm from the tooth opening. In contrast to the closed state in which the working arm enters the tooth opening by the biasing of the torque spring, the opening state occurs when the working arm is retracted from the tooth opening to the needle bed side against the biasing of the torque spring. In order to open the sinker, the rear cam for controlling the sinker that acts on the passive arm of the sinker faces the rear position farther from the tooth opening than the sinker support on the carriage that runs along the needle bed. Mounted on. The torque spring is maximally compressed in the open state to maximize the stress, and the stress is reduced in the closed state. Under no load where there is no knitted fabric to be pushed down at the mouth, the working arm enters the mouth as much as possible and the stress of the torque spring is minimized. If a large pressing force is to be obtained in the closed state, the stress of the torque spring in the open state increases, which may exceed the limit of the spring.

以上のような可動シンカーの基本的な構成は、特許文献１に開示されている。特許文献２には、作用腕が進退する針床先端のシンカー案内溝に編糸が落下するのを防ぐ編糸落下防止手段を設ける構成が開示されている。   The basic configuration of the movable sinker as described above is disclosed in Patent Document 1. Patent Document 2 discloses a configuration in which a knitting yarn fall prevention means for preventing the knitting yarn from dropping into a sinker guide groove at the tip of the needle bed where the working arm advances and retreats is disclosed.

本発明によれば、揺動変位可能なシンカーの開状態と閉状態とを切換えるシンカーカムは、キャリッジに搭載され、シンカーを直接操作する付勢カム面と開閉カム面とを有する。開閉カム面は、シンカーの受動腕に対して作用する凹凸で、シンカーの作用腕が歯口に進入する閉状態と、作用腕が歯口から退出する開状態との切換えを制御する。付勢カム面は、押圧力を作用させる方向に凹凸を有し、トルクばねの先端を押圧して、トルクばねを介してシンカーを、作用腕が歯口に進入する方向に付勢し、押圧力を、閉状態で強くしても、開状態では弱くすることができる。トルクばねの応力が開状態で閉状態よりも大きくなるようなことはなく、キャリッジに搭載するシンカーカムで直接制御する可動シンカーでも、シンカー開閉時にトルクばねの応力振幅が大きくならないようにすることができる。   According to the present invention, a sinker cam that switches between an open state and a closed state of a swingable and displaceable sinker is mounted on a carriage and has an urging cam surface and an opening / closing cam surface that directly operate the sinker. The open / close cam surface is an unevenness acting on the passive arm of the sinker, and controls switching between a closed state in which the working arm of the sinker enters the mouth and an open state in which the working arm exits from the mouth. The urging cam surface has irregularities in the direction in which the pressing force is applied, presses the tip of the torque spring, urges the sinker through the torque spring in the direction in which the operating arm enters the tooth opening, and presses it. Even if the pressure is increased in the closed state, it can be decreased in the open state. Torque spring stress does not become larger in the open state than in the closed state, and even with a movable sinker that is directly controlled by a sinker cam mounted on the carriage, the stress amplitude of the torque spring should not be increased when the sinker is opened and closed. it can.

また本発明によれば、押圧力調整手段で、シンカーの閉状態でのシンカーカムの付勢カム面の位置を、押圧力を作用させる方向に関して変更することができる。この押圧力で、歯口に進出させた編針のフックに新ループを形成する編糸が給糸された後、フックを歯口から退出させて針床に引込んでいる間に、編針に係止されている旧ループの編糸は、シンカーの編糸受け部によって押込まれる。押圧力の変更で、編目の大きさや編糸の強弱など、編地を編成する際の条件に対応して、シンカーが編糸を押込む力を調整することができる。   Further, according to the present invention, the position of the biasing cam surface of the sinker cam in the closed state of the sinker can be changed with the pressing force adjusting means with respect to the direction in which the pressing force is applied. With this pressing force, after the knitting yarn forming a new loop is fed to the hook of the knitting needle that has advanced to the tooth opening, the hook is pulled out of the tooth opening and pulled into the needle bed, and then locked to the knitting needle. The knitting yarn of the old loop is pushed by the knitting yarn receiving portion of the sinker. By changing the pressing force, the force with which the sinker pushes the knitting yarn can be adjusted in accordance with conditions for knitting the knitted fabric such as the size of the stitch and the strength of the knitting yarn.

また本発明によれば、シンカーカムは、トルクばねの先端に臨む付勢カム面が形成されるトルクばね制御カムと、シンカーの受動腕に臨む開閉カム面が形成される開閉制御カムとに分けて設けられる。トルクばね制御カムを従来の前部カム、開閉制御カムを従来の後部カムと同様に配置して、シンカー開閉時の応力振幅が大きくならないようにすることができる。   According to the present invention, the sinker cam is divided into a torque spring control cam in which an urging cam surface facing the tip of the torque spring is formed and an opening / closing control cam in which an opening / closing cam surface facing the passive arm of the sinker is formed. Provided. The torque spring control cam can be arranged in the same manner as the conventional front cam and the open / close control cam can be arranged in the same manner as the conventional rear cam, so that the stress amplitude at the time of opening and closing the sinker can be prevented.

また本発明によれば、シンカーカムは、シンカーの受動腕の先端とトルクばねの他端とを、針床側から突出する二つのバットとして、対向する開閉カム面と付勢カム面との間に収容して駆動することができる。   Further, according to the present invention, the sinker cam has a tip between the passive arm of the sinker and the other end of the torque spring as two bats projecting from the needle bed side, and between the opening / closing cam surface and the biasing cam surface. Can be accommodated and driven.

図１は、実施例１として、可動シンカー１０を備える横編機１の概略的な構成および動作を、図１（ａ）は閉状態、図１（ｂ）は開状態でそれぞれ示す。横編機１は、歯口２側で編地を編成するために、針床３を、基台４にニードルプレート５を並設して形成する。紙面に垂直な方向に、一定のピッチで並設されるニードルプレート５の間には、針溝が形成され、べら針や複合針などの編針が収容される。基台４とニードルプレート５とは、紙面に垂直な方向に貫通するワイヤ６で位置決めされる。基台４が歯口２に臨む先端には、シンカー案内溝４ａが設けられる。   FIG. 1 shows a schematic configuration and operation of a flat knitting machine 1 including a movable sinker 10 as Example 1, in which FIG. 1 (a) is in a closed state and FIG. 1 (b) is in an open state. The flat knitting machine 1 forms the needle bed 3 by arranging the needle plate 5 on the base 4 in order to knit the knitted fabric on the side of the tooth opening 2. A needle groove is formed between needle plates 5 arranged in parallel at a constant pitch in a direction perpendicular to the paper surface, and knitting needles such as a latch needle and a compound needle are accommodated. The base 4 and the needle plate 5 are positioned by a wire 6 that penetrates in a direction perpendicular to the paper surface. A sinker guide groove 4 a is provided at the tip of the base 4 facing the tooth opening 2.

可動シンカー１０は、シンカー１１およびトルクばね１２を含む。ただし、シンカー１１とトルクばね１２とは一体化されている。このような可動シンカー１０は、歯口２に臨む針床３の先端側に、配列して複数設けられる。各シンカー１１は、支承部１１ａと、支承部１１ａから歯口２側に湾曲して延びる作用腕１１ｂと、支承部１１ａから後方に突出するように設けられる受動腕１１ｃとを有する。トルクばね１２は、シンカー１１の支承部１１ａと作用腕１１ｂとの間を基端１２ｂとして先端１２ａまで延びる。トルクばね１２の先端１２ａは、ニードルプレート５の前方に突出する。本実施例の可動シンカー１０では、シンカー１１とトルクばね１２とは、板状の金属素材から打抜き加工で一体的に形成されているけれども、シンカー１１とトルクばね１２とは別体でもよい。別体の場合、たとえば特許文献１と同様に、トルクばねとして線ばねを用い、シンカーに設けるばね係止部に係止させればよい。   The movable sinker 10 includes a sinker 11 and a torque spring 12. However, the sinker 11 and the torque spring 12 are integrated. A plurality of such movable sinkers 10 are arranged and arranged on the distal end side of the needle bed 3 facing the tooth opening 2. Each sinker 11 has a support portion 11a, an action arm 11b that curves and extends from the support portion 11a to the side of the tooth opening 2, and a passive arm 11c that is provided so as to protrude rearward from the support portion 11a. The torque spring 12 extends from the support portion 11a of the sinker 11 and the working arm 11b to the tip end 12a with the base end 12b. The tip 12 a of the torque spring 12 protrudes forward of the needle plate 5. In the movable sinker 10 of the present embodiment, the sinker 11 and the torque spring 12 are integrally formed by punching from a plate-shaped metal material, but the sinker 11 and the torque spring 12 may be separate. In the case of a separate body, for example, similarly to Patent Document 1, a wire spring may be used as a torque spring and locked to a spring locking portion provided in the sinker.

支承部１１ａは、円弧状の外周が歯口２近傍のニードルプレート５に設ける円弧状の凹部であるシンカー支持部５ａに嵌合して、揺動変位可能に支持される。可動シンカー１０では、シンカー１１がニードルプレート５に設けるシンカー収容部５ｂに収容され、作用腕１１ｂが歯口２内に進入する方向に揺動する閉状態と、作用腕１１ｂが歯口２から離れる方向に揺動する開状態とを、切換え可能である。切換えは、針床３に沿って往復走行するキャリッジに搭載されるシンカーカムのトルクばね制御カム１３と開閉制御カム１４とによって、可動シンカー１０を直接操作して行う。トルクばね制御カム１３には、トルクばね１２の先端１２ａに対する凹凸で押圧力を作用させる付勢カム面１３ａが形成される。開閉制御カム１４には、シンカー１１の受動腕１１ｃに対する凹凸で開閉を切換える開閉カム面１４ａが形成される。トルクばね１２の先端１２ａと受動腕１１ｃとは、シンカー収容部５ｂの前方と後方とで、ニードルプレート５および基台４で形成する針床３の外方に突出するので、付勢カム面１３ａと開閉カム面１４ａとの作用を、それぞれ受けることができる。   The support portion 11a is supported so as to be swingable and displaceable by fitting it into a sinker support portion 5a which is an arc-shaped recess provided in the needle plate 5 in the vicinity of the mouth 2 with an arc-shaped outer periphery. In the movable sinker 10, the sinker 11 is housed in the sinker housing portion 5 b provided on the needle plate 5, the closed state where the working arm 11 b swings in the direction of entering the tooth mouth 2, and the working arm 11 b is separated from the tooth mouth 2. The open state that swings in the direction can be switched. The switching is performed by directly operating the movable sinker 10 by a torque spring control cam 13 and an opening / closing control cam 14 of a sinker cam mounted on a carriage that reciprocates along the needle bed 3. The torque spring control cam 13 is formed with an urging cam surface 13 a for applying a pressing force with unevenness with respect to the tip 12 a of the torque spring 12. The opening / closing control cam 14 is formed with an opening / closing cam surface 14 a that switches between opening and closing by unevenness with respect to the passive arm 11 c of the sinker 11. Since the tip 12a and the passive arm 11c of the torque spring 12 protrude outward from the needle bed 3 formed by the needle plate 5 and the base 4 at the front and rear of the sinker housing portion 5b, the biasing cam surface 13a And the opening / closing cam surface 14a.

図１（ａ）に示すように、閉状態では、トルクばね制御カム１３の付勢カム面１３ａの凸の部分でトルクばね１２の先端１２ａを下方に押圧する。開閉制御カム１４の開閉カム面１４ａは、凹の部分が対応する位相関係となる。トルクばね１２は、基端１２ｂを介して、シンカー１１を、図の時計回り方向に揺動させるように付勢する。シンカー１１は、作用腕１１ｂが歯口２側に進入するように付勢される。作用腕１１ｂは、編糸受け部１１ｄ、およびシンカーループ形成部１１ｅを有する。シンカー１１の支承部１１ａは、円弧状の外周の仮想的な中心を支点１１ｆとして揺動変位する。   As shown in FIG. 1A, in the closed state, the tip 12a of the torque spring 12 is pressed downward by the convex portion of the biasing cam surface 13a of the torque spring control cam 13. The opening / closing cam surface 14a of the opening / closing control cam 14 has a phase relationship corresponding to the concave portion. The torque spring 12 urges the sinker 11 to swing in the clockwise direction in the figure via the base end 12b. The sinker 11 is urged so that the working arm 11b enters the tooth opening 2 side. The working arm 11b has a knitting yarn receiving portion 11d and a sinker loop forming portion 11e. The support portion 11a of the sinker 11 swings and displaces with the virtual center of the arcuate outer periphery as a fulcrum 11f.

図１（ｂ）に示すように、開状態でシンカー１１の受動腕１１ｃは、開閉カム面１４ａの凸の部分によって押下げられ、シンカー１１を反時計まわり方向に揺動変位させ、作用腕１１ｂが歯口２から針床３側に退出するように操作することができる。トルクばね制御カム１３の付勢カム面１３ａは、凹の部分が対応する位相関係となるけれども、凹の部分は、トルクばね１２の先端１２ａの上昇を規制するストッパーとして機能させることができる。先端１２ａの上昇を規制する位置は、特許文献１、２のようにニードルプレートに固定する位置よりも高くすることができるので、トルクばね１２の応力を小さくすることができる。開状態で、付勢カム面１３ａがトルクばね１２の先端１２ａから離れて不作用になるようにすれば、トルクばね１２の応力を最小にすることができる。付勢カム面１３ａは、シンカー１１の支承部１１ａと作用腕１１ｂとの間を基端１２ｂとするトルクばね１２の先端１２ａへの押圧力で、トルクばね１２によるシンカー１１への付勢を調整するので、閉状態で強くしても、開状態では弱くすることができる。トルクばね１２の応力が開状態で閉状態よりも大きくなるようなことはなく、キャリッジに搭載するシンカーカムで直接制御する可動シンカー１０でも、シンカー開閉時にトルクばね１２の応力振幅が大きくならないようにすることができる。   As shown in FIG. 1B, in the open state, the passive arm 11c of the sinker 11 is pushed down by the convex portion of the opening / closing cam surface 14a, and the sinker 11 is oscillated and displaced in the counterclockwise direction. Can be operated so as to retreat from the mouth 2 to the needle bed 3 side. The urging cam surface 13a of the torque spring control cam 13 has a phase relationship corresponding to the concave portion, but the concave portion can function as a stopper that restricts the rise of the tip 12a of the torque spring 12. Since the position where the rise of the tip 12a is restricted can be made higher than the position fixed to the needle plate as in Patent Documents 1 and 2, the stress of the torque spring 12 can be reduced. If the biasing cam surface 13a is separated from the tip 12a of the torque spring 12 and becomes inactive in the open state, the stress of the torque spring 12 can be minimized. The urging cam surface 13a adjusts the urging of the torque spring 12 to the sinker 11 by the pressing force to the tip 12a of the torque spring 12 having the base end 12b between the support portion 11a and the working arm 11b of the sinker 11. Therefore, even if it is strengthened in the closed state, it can be weakened in the open state. The stress of the torque spring 12 does not become larger in the open state than in the closed state, and even in the movable sinker 10 that is directly controlled by the sinker cam mounted on the carriage, the stress amplitude of the torque spring 12 is not increased when the sinker is opened and closed. can do.

以上のようなトルクばね制御カム１３および開閉制御カム１４は、たとえば特許文献１の第１図の「前部カム４」および「後部カム３」と同様の位置に配置して、開状態で「押さえ板３４」が「線バネ２８の遊端部２８ａが押し下げ付勢される」位置よりも高い位置に付勢カム面１３ａの凹部を設けて、トルクばね１２の先端１２ａの上昇を規制し、開閉時の応力振幅が大きくならないようにすることができる。なお、本実施例でも、シンカー１１は、ニードルプレート５に設ける帯金貫通部５ｃを紙面に垂直な方向に貫通する帯金１５で、上方に浮上しないように押えられる。   The torque spring control cam 13 and the opening / closing control cam 14 as described above are arranged at the same positions as the “front cam 4” and “rear cam 3” in FIG. The pressing plate 34 is provided with a concave portion of the biasing cam surface 13a at a position higher than the position where the free end portion 28a of the wire spring 28 is pressed and biased to restrict the rise of the tip 12a of the torque spring 12, The stress amplitude at the time of opening and closing can be prevented from becoming large. Also in the present embodiment, the sinker 11 is pressed so as not to float upward by the band 15 penetrating the band penetrating portion 5c provided in the needle plate 5 in the direction perpendicular to the paper surface.

本実施例は、シンカー１１の閉状態で、シンカーカムであるトルクばね制御カム１３の付勢カム面１３ａの位置を、押圧力を作用させる方向に関して変更して、トルクばね１２の先端１２ａへの押圧力を調整する押圧力調整手段１６をさらに含む。押圧力調整手段１６は、制御板１６ａ、ピニオン歯車１６ｂおよび取付けベース１６ｃを有する。ピニオン歯車１６ｂは、図示を省略しているモーターなどの駆動源で回転駆動される。制御板１６ａは、図２（ａ）に示すように、ピニオン歯車１６ｂと噛合するラック１６ｆを有する。ピニオン歯車１６ｂの回転で、制御板１６ａは、図１の紙面に垂直な方向に移動する。制御板１６ａには、溝カム１６ｄおよび案内溝１６ｅが形成される。溝カム１６ｄおよび案内溝１６ｅにはピン１６ｇおよび案内ねじ１６ｈの軸部がそれぞれ嵌合する。制御板１６ａを図１の紙面に垂直な方向に移動させると、トルクばね制御カム１３を図１の上下方向に移動させて、付勢カム面１３ａの上下方向の位置を変更し、トルクばね１２の先端１２ａに作用させる押圧力を弱強に調整することができる。取付けベース１６ｃは、押圧力調整手段１６をキャリッジに取付けて支持するために用いられる。   In this embodiment, in the closed state of the sinker 11, the position of the urging cam surface 13a of the torque spring control cam 13, which is a sinker cam, is changed with respect to the direction in which the pressing force is applied, and the torque spring 12 is moved toward the tip 12a. Further included is a pressing force adjusting means 16 for adjusting the pressing force. The pressing force adjusting means 16 includes a control plate 16a, a pinion gear 16b, and a mounting base 16c. The pinion gear 16b is rotationally driven by a drive source such as a motor (not shown). As shown in FIG. 2A, the control plate 16a has a rack 16f that meshes with the pinion gear 16b. With the rotation of the pinion gear 16b, the control plate 16a moves in a direction perpendicular to the paper surface of FIG. A groove cam 16d and a guide groove 16e are formed in the control plate 16a. The shaft portions of the pin 16g and the guide screw 16h are fitted into the groove cam 16d and the guide groove 16e, respectively. When the control plate 16a is moved in a direction perpendicular to the paper surface of FIG. 1, the torque spring control cam 13 is moved in the vertical direction in FIG. 1 to change the vertical position of the urging cam surface 13a. It is possible to adjust the pressing force applied to the tip 12a of the lens slightly. The mounting base 16c is used for mounting and supporting the pressing force adjusting means 16 on the carriage.

このような押圧力調整手段１６を用いることによって、シンカー１１の閉状態での付勢カム面１３ａの位置を、押圧力を作用させる方向に関して変更することができる。この押圧力で、歯口２に進出させた編針のフックに新ループを形成する編糸の給糸を受けた後、フックを歯口２から退出させて針床３に引込んでいる間は、編針に係止されている旧ループの編糸がシンカー１１の編糸受け部１１ｄによって押込まれる。押圧力の変更で、編目の大きさや編糸の強弱など、編成条件に対応して、シンカー１１が編糸を押込む力を調整することができる。   By using such a pressing force adjusting means 16, the position of the urging cam surface 13a in the closed state of the sinker 11 can be changed with respect to the direction in which the pressing force is applied. While receiving the knitting yarn forming a new loop on the hook of the knitting needle advanced to the tooth opening 2 with this pressing force, the hook is retracted from the tooth opening 2 and pulled into the needle bed 3. The knitting yarn of the old loop locked to the knitting needle is pushed in by the knitting yarn receiving portion 11d of the sinker 11. By changing the pressing force, the force with which the sinker 11 pushes the knitting yarn can be adjusted in accordance with the knitting conditions such as the size of the stitch and the strength of the knitting yarn.

なお、押圧力調整手段１６は、制御板１６ａにラック１６ｆを設けて、ピニオン歯車１６ｂを介して駆動するばかりではなく、特に、２段階の切換えを行うような場合、シリンダーやソレノイドなどのアクチュエーターで、制御板１６ａを直接駆動してもよい。また、トルクばね制御カム１３をアクチュエータで直接移動させてもよい。切換えの段数が多い場合、ボールねじを使用してもよい。   The pressing force adjusting means 16 is not only provided with a rack 16f on the control plate 16a and driven via the pinion gear 16b. In particular, when switching in two stages is performed, an actuator such as a cylinder or a solenoid is used. The control plate 16a may be directly driven. Further, the torque spring control cam 13 may be directly moved by an actuator. A ball screw may be used when the number of switching stages is large.

図２は、実施例１の横編機１で、キャリッジに搭載され、編針としてべら針を使用する場合に用いるカムの配置を簡略化して示す。図２（ａ）は、トルクばね制御カム１３および開閉制御カム１４の配置を示し、上方が針床３に臨む方向となる。図２（ｂ）は、編目形成用カム１６および目移し用カム１７の配置を含む。編目形成用カム１６には、度山１６ａ，１６ｂとニードルレイジングカム１６ｃとが含まれる。カムは、キャリッジが左行する場合も右行する場合も同等の作用を行うけれども、以下の説明は、キャリッジが左行する場合を想定して行う。   FIG. 2 shows a simplified arrangement of cams used in the flat knitting machine 1 of the first embodiment, which is mounted on a carriage and used when a latch needle is used as a knitting needle. FIG. 2A shows the arrangement of the torque spring control cam 13 and the opening / closing control cam 14, with the upper side facing the needle bed 3. FIG. 2B includes the arrangement of the stitch forming cam 16 and the transfer cam 17. The stitch forming cam 16 includes crests 16a and 16b and a needle raising cam 16c. Although the cam performs the same operation whether the carriage moves to the left or the right, the following description is made on the assumption that the carriage moves to the left.

トルクばね制御カム１３は、制御板１６ａをラック１６ｆへの駆動で紙面の左方に移動させれば、溝カム１６ｄが嵌合しているピン１６ｇを押上げ、付勢カム面１３ａの位置を図の上方に変えることができる。本実施例の溝カム１６ｄは、３段階で付勢カム面１３ａの位置を変更することができる。溝カム１６ｄの段数の変化で、位置の切換え段数を変えることができ、また連続した傾斜溝にすれば、無段階で付勢カム面１３ａの位置を変更することができる。案内溝１６ｅには、取付けベース１６ｃに固定される案内ねじ１６ｈの軸部が嵌合し、制御板１６ａが図の左右に移動するように案内する。トルクばね制御カム１３は、図の上下方向の案内溝１６ｉを有し、取付けベース１６ｃに設ける案内ねじ１６ｊの軸部が案内溝１６ｉに嵌合し、上下に移動するように案内される。図２（ａ）の上方は、図１では下方となる。   When the torque spring control cam 13 moves the control plate 16a to the left of the page by driving the rack 16f, the torque spring control cam 13 pushes up the pin 16g with which the groove cam 16d is fitted, and moves the position of the biasing cam surface 13a. It can be changed upward in the figure. The groove cam 16d of this embodiment can change the position of the urging cam surface 13a in three stages. The position switching step number can be changed by changing the step number of the groove cam 16d, and the position of the urging cam surface 13a can be changed steplessly by using a continuous inclined groove. A shaft portion of a guide screw 16h fixed to the mounting base 16c is fitted in the guide groove 16e, and the control plate 16a is guided so as to move left and right in the drawing. The torque spring control cam 13 has a guide groove 16i in the vertical direction in the figure, and a shaft portion of a guide screw 16j provided on the mounting base 16c is fitted into the guide groove 16i and guided so as to move up and down. The upper side of FIG. 2A is the lower side in FIG.

開閉制御カム１４は、開閉カム面１４ａの凸部分が移動カム１４ｂに設けられる。移動カム１４ｂは、左行開始後にシンカー１２の受動腕１２ｃに当接すると、溝１４ｃに沿って右方に移動し、歯口２で編針に給糸を受ける位置Ａで、シンカー１１の作用腕１１ｂを歯口２から退出させてシンカー１２を開状態にする。また、開閉制御カム１４には、キャリッジの走行方向の先行側で、いったんシンカー１１の編糸受け部１１ｄを歯口２から退出させるための可動カム１４ｄも設けられている。キャリッジが右行する場合は、可動カム１４ｅに切換えられる。なお、度山１６ｂが編針を引込む位置Ｂでは、付勢カム面１３ａの凸の部分が対応するようにしている。付勢カム面１３ａの位置で、トルクばね１２の先端１２ａに作用する押圧力を調整することができ、付勢カム面１３ａの位置が針床３に近いと大きくなり、針床３から離れると小さくなる。   In the opening / closing control cam 14, the convex portion of the opening / closing cam surface 14a is provided on the moving cam 14b. When the moving cam 14b comes into contact with the passive arm 12c of the sinker 12 after the left line starts, the moving cam 14b moves to the right along the groove 14c, and at the position A where the yarn is fed to the knitting needle at the tooth opening 2, the working arm of the sinker 11 is moved. 11b is withdrawn from the mouth 2 and the sinker 12 is opened. The opening / closing control cam 14 is also provided with a movable cam 14d for temporarily retracting the knitting yarn receiving portion 11d of the sinker 11 from the tooth mouth 2 on the leading side in the traveling direction of the carriage. When the carriage moves to the right, it is switched to the movable cam 14e. It should be noted that the convex portion of the urging cam surface 13a corresponds to the position B where the stitch 16b retracts the knitting needle. The pressing force acting on the tip 12a of the torque spring 12 can be adjusted at the position of the urging cam surface 13a. When the position of the urging cam surface 13a is close to the needle bed 3, it increases. Get smaller.

図３は、図１の可動シンカー１０を構成するシンカー１１およびトルクばね１２と、針床３を構成する基台４およびニードルプレート５の形状を示す。
トルクばね１２では、先端１２ａと基端１２ｂとの間で折返す湾曲部１２ｃを設けることができる。湾曲部１２ｃは、シンカー１１の支承部１１ａの内側で、支点１１ｆを迂回する形状にすることができる。支点１１ｆは、支承部１１ａの外周となる円弧の仮想的な中心である。 FIG. 3 shows shapes of the sinker 11 and the torque spring 12 that constitute the movable sinker 10 of FIG. 1, and the base 4 and the needle plate 5 that constitute the needle bed 3.
The torque spring 12 can be provided with a curved portion 12c that turns back between the distal end 12a and the proximal end 12b. The curved portion 12c can be shaped to bypass the fulcrum 11f inside the support portion 11a of the sinker 11. The fulcrum 11f is an imaginary center of an arc serving as the outer periphery of the support portion 11a.

ニードルプレート５は、シンカー支持部５ａ、シンカー収容部５ｂおよび帯金貫通部５cを有し、下部を基台４に形成される溝に挿入して、固定される。   The needle plate 5 has a sinker support portion 5a, a sinker housing portion 5b, and a band penetrating portion 5c, and the lower portion is inserted into a groove formed in the base 4 and fixed.

トルクばね１２は、シンカー１１に揺動変位のためのトルクを発生可能であれば、形状が異なってもよい。本実施例のように、シンカー１１とトルクばね１２とを一体化する場合は、トルクばね１２もシンカー１１と同じ板材から形成する必要があるけれども、一体化することによって、可動シンカーを構成する部品の点数を減らし、組立て工数を低減することができる。トルクばね１２とシンカー１１と別体とすれば、トルクばね１２は、シンカー１１と異なる弾性材料を使用することができる。   The torque spring 12 may have a different shape as long as it can generate torque for swinging displacement in the sinker 11. When the sinker 11 and the torque spring 12 are integrated as in the present embodiment, the torque spring 12 also needs to be formed from the same plate material as the sinker 11, but the components constituting the movable sinker by integrating the sinker 11 and the torque spring 12 The number of points can be reduced, and the assembly man-hour can be reduced. If the torque spring 12 and the sinker 11 are separated, the torque spring 12 can use an elastic material different from that of the sinker 11.

図４は、実施例２として、可動シンカー３０を備える横編機２１の概略的な構成および動作を、図４（ａ）は閉状態、図４（ｂ）は開状態でそれぞれ示す。本実施例では、シンカー３１の受動腕３１ｃは、作用腕３１ｂと支承部３１ａとの間から分岐して、ニードルプレート２５の上方に突出する。トルクばね３２の先端３２ａは、受動腕３１ｃよりも後方の位置で、ニードルプレート２５の上方に突出する。ニードルプレート２５は、基台２４とともに針床２３を形成し、受動腕３１ｃとトルクばね３２の先端３２ａとが突出するのは、針床３２の外方となる。   FIG. 4 shows a schematic configuration and operation of a flat knitting machine 21 including a movable sinker 30 as Example 2, in which FIG. 4 (a) is in a closed state and FIG. 4 (b) is in an open state. In the present embodiment, the passive arm 31 c of the sinker 31 branches from between the working arm 31 b and the support portion 31 a and protrudes above the needle plate 25. The tip 32a of the torque spring 32 protrudes above the needle plate 25 at a position behind the passive arm 31c. The needle plate 25 forms the needle bed 23 together with the base 24, and the passive arm 31c and the tip 32a of the torque spring 32 protrude from the outside of the needle bed 32.

シンカーカムは、シンカー３１の受動腕３１ｃの先端とトルクばね３２の先端３２ａとを、針床３３から突出する二つのバットとして、開閉制御カム３４の開閉カム面３４ａと、トルクばね制御カム３３の付勢カム面３３ａとが対向する間に収容する。本実施例は、実施例１とはカムの配置が異なるけれども、それぞれ対応するものが設けられ、作用する方向に関するカム面の凹凸のパターンも同様にすることができる。圧力調整手段３６は、実施例１の押圧力調整手段１６と同様に、トルクばね３２の先端３２ａに作用する押圧力を調整することができる。   The sinker cam uses the tip of the passive arm 31 c of the sinker 31 and the tip 32 a of the torque spring 32 as two bats protruding from the needle bed 33, and the opening and closing cam surface 34 a of the opening and closing control cam 34 and the torque spring control cam 33. It is accommodated while facing the biasing cam surface 33a. Although the present embodiment is different from the first embodiment in the arrangement of the cams, corresponding ones are provided, and the cam surface unevenness pattern in the acting direction can be made the same. The pressure adjusting means 36 can adjust the pressing force acting on the tip 32a of the torque spring 32, similarly to the pressing force adjusting means 16 of the first embodiment.

図５は、図４の可動シンカー３０を構成するシンカー３１およびトルクばね３２と、針床２３を構成する基板２４およびニードルプレート２５の形状を示す。   FIG. 5 shows shapes of the sinker 31 and the torque spring 32 that constitute the movable sinker 30 of FIG. 4, and the substrate 24 and the needle plate 25 that constitute the needle bed 23.
