Description

本発明は、横編機のキャリッジに搭載されて、歯口に各種部材を進退させるように駆動する横編機のキャリッジ搭載ユニットに関する。   The present invention relates to a carriage mounting unit of a flat knitting machine that is mounted on a carriage of a flat knitting machine and is driven to move various members forward and backward in a tooth opening.

従来から、横編機では、歯口に沿って直線状に延びる針床に、多数の針溝を形成して編針を収容している。編地の編成は、たとえば針床に沿ってキャリッジを往復走行させ、キャリッジに搭載されるカム機構で編針を歯口に進退させて行っている。歯口では、針床から進出する編針の先端に、キャリッジが連行する給糸部材からの編糸を供給する。編針を針床に引込むことによって編目が編成される。基本的な編目であるニットでは、新たな編目編成で編針が歯口から退避する際に、既に編成されている編目が編針の先端を乗り越えて、編針から離脱し、歯口に移行して編地の一部となる。
横編機では、歯口を挟んで少なくとも前後一対の針床が対向する形式のものが多く使用されている。前後の針床を利用して編成を行うことによって、多様な編地を編成することができる。前後の針床を備える横編機では、前後の針床間で編目を移動させる目移しの動作も行われる。目移し動作では、編目を保持する編針を歯口に進出させ、先端から遅れて歯口に進出する編目を、対向する針床側から歯口に進出させる編針の先端で受けて移行させる。
横編機の歯口で編地を編成する際のニット時または目移し時に、編針の歯口への進出時に、編針の先端とともに編目が歯口に進出するように編目が浮き気味になることがある。編目が浮き気味になると、「目かぶり」や「目落ち」などと呼ばれる現象が発生することがある。このような現象を防ぐために、編目の浮き上がりを押さえるステッチプレッサと呼ばれる部材を歯口に進退させる機構を、キャリッジに備えるようにしている(たとえば、特許第2602156号公報参照。)。
特許第2602156号公報には、大略的にL字形状で、横棒部分を歯口に進出させて編目を押さえる第1および第2プレッサとを一対の部材として、編針として使用するべら針のべらを編針が歯口に進出する際に開かせる刷毛を他の部材として、合計3つの部材を、キャリッジの走行方向に往復移動する溝カム板を介して1つのモータで駆動する横編機の編地プレッサーが開示されている。モータは、出力軸がキャリッジの往復走行方向に垂直な状態で配置され、出力軸に装着されるピニオン歯車で、溝カム板のラックを駆動して、溝カム板を往復駆動している。L字形のプレッサは方向性を有するので、キャリッジの走行方向に合わせて第1プレッサと第2プレッサとを切換える。刷毛は、基本的には常に歯口に進出させておくけれども、プレッサの歯口への進退時に、プレッサの移動軌跡と干渉しないように、退避させる必要がある。
なお、キャリッジは前後の針床にそれぞれ設けられ、歯口をまたぐブリッジで連結されている。前後の針床のキャリッジにそれぞれ異なる方向のプレッサを搭載し、各プレッサを1つのモータで駆動するものもある(たとえば、特公平3−66415号公報参照。)。特公平3−66415号公報では、モータの出力軸の両端にクランクアームと回転する偏心カムとを設け、プレッサと刷毛とをそれぞれ駆動するようにしている。
編針がべら針ではなく、針本体とスライダとを相対移動させて針本体のフックをスライダで開閉する複合針であれば、刷毛は不要である。しかしながら、たとえば、編針の先端が歯口に進出して編糸の供給を受ける際に、編糸を編針の先端のフックに案内するヤーンガイドなどの部材を、ステッチプレッサの進退時に歯口から退避させる機能を、刷毛を進退させる機能に代えて持たせることが可能であれば好ましいと考えられる。
歯口には、編針間で揺動可能に可動シンカが配設される場合もある。可動シンカは、編針に係止された編目を、新たな編目編成のために編針が歯口に進出する際には編針とともに歯口に進出しないように押さえて保持し、編目がノックオーバ可能なクリア位置を通過可能にする機能を有している。本件出願人は、このような可動シンカを、ステッチプレッサの歯口への進退時には歯口から退避させる横編機も開示している(たとえば、特公平6−72347号公報参照。)。特公平6−72347号公報では、モータの出力軸の両端にクランクアームを設け、一方のクランクアームでリンク機構を介してステッチプレッサを揺動変位させ、他方のクランクアームで可動シンカを揺動変位させるカム溝カム板を摺動変位させている。
特許第2602156号公報のように、1つのモータで、一対のプレッサと刷毛とを駆動する構成であれば、特公平3−66415号公報のように一対のプレッサを2つのモータで駆動する構成よりも、モータの数を減らすことができる。また、ほとんど前後の針床の一方のみで編成する編地に対しては、その針床に沿って往復走行するキャリッジに、一対のプレッサを駆動するユニットを搭載するようにしないと、キャリッジの往復方向でプレッサの作用を同等とすることができない。
しかしながら、特許第2602156号公報では、溝カム板を介して一対のプレッサを駆動する。溝カム板には、各プレッサを、キャリッジの往復走行方向とは垂直な歯口への進退方向に、L字状のプレッサの縦棒部分を揺動変位させるための溝カムが形成されている。駆動のためには、溝カム板を、溝カムの長さ分だけは変位させなければならない。したがって、溝カム板を取付けるためには、キャリッジの往復移動方向となる幅方向に、少なくとも一対のプレッサの縦棒部分の間隔と、溝カムの移動ストロークとの和以上を有する充分なスペースを必要とする。
特公平3−66415号公報および特公平6−72347号公報のように、クランクアームなどを使用してプレッサを駆動すれば、キャリッジの走行方向に移動する溝カム板を用いる場合のようなスペースは必要とはならないけれども、クランクアームでは、一対のプレッサのうちの一方のみを駆動して、他方を静止させておくことが困難である。
キャリッジに搭載され、編針を駆動するカム機構などでは、小型化、軽量化が進められている。キャリッジが小型化、軽量化されれば、キャリッジを往復走行させる駆動機構の小型化および省エネルギ化を図ることができる。しかしながら、キャリッジ搭載ユニットが大型であれば、キャリッジの小型化および軽量化を図ることができない。
Conventionally, a flat knitting machine accommodates knitting needles by forming a large number of needle grooves in a needle bed that extends linearly along the mouth. Knitting of the knitted fabric is performed, for example, by reciprocating the carriage along the needle bed and advancing and retracting the knitting needle to the tooth opening by a cam mechanism mounted on the carriage. In the tooth opening, the knitting yarn from the yarn supplying member accompanied by the carriage is supplied to the tip of the knitting needle that advances from the needle bed. The stitches are knitted by drawing the knitting needles into the needle bed. In a knit that is a basic stitch, when the knitting needle is retracted from the tooth opening in a new stitch knitting, the already knitted stitch gets over the tip of the knitting needle, disengages from the knitting needle, transitions to the tooth opening and knitting. Become part of the earth.
In flat knitting machines, a machine of a type in which at least a pair of front and back needle beds are opposed to each other with a tooth opening interposed therebetween is often used. Various knitted fabrics can be knitted by knitting using the front and back needle beds. In a flat knitting machine having front and rear needle beds, a transfer operation for moving the stitches between the front and rear needle beds is also performed. In the transfer operation, the knitting needle that holds the stitch is advanced to the tooth opening, and the stitch that is advanced from the leading edge to the tooth opening is received by the tip of the knitting needle that advances from the opposite needle bed side to the tooth opening and is transferred.
At the time of knitting or transferring when knitting the fabric with the flat knitting machine's mouth, when the knitting needle advances to the mouth, the knitting needle will float with the tip of the knitting needle to advance into the mouth. There is. When the stitches are lifted, a phenomenon called “eye fogging” or “eye drop” may occur. In order to prevent such a phenomenon, the carriage is provided with a mechanism for advancing and retracting a member called a stitch presser that suppresses the lifting of the stitch to the tooth opening (see, for example, Japanese Patent No. 2602156).
Japanese Patent No. 2602156 discloses a latch needle used as a knitting needle as a pair of a first and second presser, which are generally L-shaped and have a horizontal bar portion advanced into a tooth opening to hold a stitch. The knitting of a flat knitting machine that drives a total of three members with one motor via a groove cam plate that reciprocates in the traveling direction of the carriage, with the brush that opens when the knitting needle advances into the mouth as the other member A ground presser is disclosed. The motor is arranged in a state where the output shaft is perpendicular to the reciprocating direction of the carriage, and the pinion gear mounted on the output shaft drives the rack of the groove cam plate to reciprocate the groove cam plate. Since the L-shaped presser has directionality, the first presser and the second presser are switched in accordance with the traveling direction of the carriage. The brush is basically always advanced to the tooth opening, but it is necessary to retract the brush so that it does not interfere with the movement locus of the presser when the presser advances to and retracts from the tooth opening.
The carriage is provided on each of the front and back needle beds, and is connected by a bridge that crosses the mouth. There is a type in which pressers in different directions are mounted on the front and rear needle bed carriages, and each presser is driven by one motor (for example, see Japanese Patent Publication No. 3-66415). In Japanese Examined Patent Publication No. 3-66415, a crank arm and a rotating eccentric cam are provided at both ends of an output shaft of a motor to drive a presser and a brush, respectively.
If the knitting needle is not a latch needle but a compound needle in which the needle body and the slider are moved relative to each other and the hook of the needle body is opened and closed with the slider, no brush is required. However, for example, when the tip of the knitting needle advances into the mouth and receives the supply of the knitting yarn, a member such as a yarn guide that guides the knitting yarn to the hook at the tip of the knitting needle is retracted from the mouth when the stitch presser advances and retreats. It is considered preferable if the function to be used can be provided instead of the function of moving the brush forward and backward.
In some cases, a movable sinker is provided at the mouth so as to be swingable between the knitting needles. The movable sinker holds and holds the stitches locked to the knitting needles so that the knitting needles do not advance into the tooth opening together with the knitting needles when the knitting needle advances into the tooth opening for a new stitch knitting. It has a function that allows the position to pass. The present applicant has also disclosed a flat knitting machine that retracts such a movable sinker from the tooth opening when the stitch presser advances and retracts to the tooth opening (see, for example, Japanese Patent Publication No. 6-72347). In Japanese Patent Publication No. 6-72347, crank arms are provided at both ends of the output shaft of the motor, and one crank arm swings and displaces the stitch presser via the link mechanism, and the other crank arm swings and displaces the movable sinker. The cam groove cam plate to be slid is displaced.
If it is the structure which drives a pair of pressers and a brush with one motor like patent 2602156 gazette, than a structure which drives a pair of pressers with two motors like Japanese Patent Publication No. 3-66415. Even the number of motors can be reduced. For a knitted fabric knitted with only one of the front and back needle beds, a carriage that reciprocates along the needle bed must be equipped with a unit that drives a pair of pressers. The direction of the presser cannot be made equal in the direction.
However, in Japanese Patent No. 2602156, a pair of pressers is driven via a groove cam plate. The groove cam plate is formed with a groove cam for swinging and displacing the vertical bar portion of the L-shaped presser in a direction in which the presser advances and retreats to the tooth mouth perpendicular to the reciprocating direction of the carriage. . For driving, the groove cam plate must be displaced by the length of the groove cam. Therefore, in order to mount the groove cam plate, a sufficient space is required in the width direction, which is the reciprocating movement direction of the carriage, having at least the sum of the distance between the vertical bar portions of the pair of pressers and the movement stroke of the groove cam. And
If the presser is driven using a crank arm or the like as in Japanese Patent Publication No. 3-66415 and Japanese Patent Publication No. 6-72347, the space as in the case of using a groove cam plate that moves in the carriage traveling direction is Although not necessary, it is difficult for the crank arm to drive only one of the pair of pressors and keep the other stationary.
A cam mechanism mounted on a carriage and driving a knitting needle has been reduced in size and weight. If the carriage is reduced in size and weight, the drive mechanism for reciprocating the carriage can be reduced in size and energy can be saved. However, if the carriage mounting unit is large, the carriage cannot be reduced in size and weight.

以下図面を参考にして本発明の好適な実施形態を詳細に説明する。
図1は、本発明の実施の一形態としての駆動ユニット1の概略的な構成を示す。駆動ユニット1は、横編機の針床に沿って往復走行するキャリッジ2に搭載され、横編機のキャリッジ搭載ユニットとして機能する。キャリッジ2は、針床から編針を進退させて編地を編成するための選択的な駆動を行う。駆動ユニット1は、編針とは独立して進退動作する部材を、キャリッジ2の走行方向に応じて切換えられる一対の部材を含めて少なくとも3つ備える。すなわち、一対のステッチプレッサ3,4、すなわち一方のステッチプレッサ3および他方のステッチプレッサ4は、キャリッジ2が図の左右方向に移動するのに応じて、相互間で切り換えられる。第3の部材として、編針としてべら針を使用する場合に、べらを開かせる刷毛5も使用する。一対のステッチプレッサ3,4および刷毛5の3つの部材は、編針が進退して編地の編成が行われる歯口6に進退して、編地編成の補助的な作用を行う。
駆動ユニット1は、単一のモータ7で各部材を駆動可能な横編機のキャリッジ搭載ユニットである。モータ7は、出力軸がモータ軸7a方向の両側に一方側出力軸8および他方側出力軸9としてそれぞれ突出し、そのモータ軸7a方向がキャリッジ2の往復走行方向と平行になるように配置される。モータ7の一方側出力軸8には、一方のステッチプレッサ3が、モータ7の一方向回転で歯口6に進出させるように、回転運動を揺動運動に変換して駆動する一方側駆動機構10が配置される。モータ7の他方側出力軸9には、他方のステッチプレッサ4が、モータ7の他方向回転で歯口6に進出させるように、回転運動を揺動運動に変換して駆動する他方側駆動機構20が配置される。一方側駆動機構10または他方側駆動機構20のいずれか一方(図1では一方側駆動機構10)に隣接して、モータ7の回転運動で一対のステッチプレッサ3,4とは異なる他の部材である刷毛5を、一対のステッチプレッサ3,4との干渉を避けるように歯口6に進退させる他部材駆動機構としてのカム駆動機構30が配置される。単一のモータ7で、一対の部材であるステッチプレッサ3,4と、他の部材である刷毛5との少なくとも3つを、モータ7の回転で各部材が歯口6に対して進退移動するように駆動する際に、キャリッジ2の往復動方向に往復動する溝カム板などを含まないので、多くの機能を備えていても、キャリッジ搭載ユニットの小型化を図ることができる。
一方側駆動機構10は二段カム11を備え、他方側駆動機構20は二段カム21を備えている。二段カム11,21には、外周に、二段にわたってカム面が形成され、ホロワ12,22のベース13,23から一定間隔で立設するローラ14,15;24,25でカム面を挟んで、ホロワ12,22を追従させる。カム面が二段に形成されているので、ローラ14,24はベース13,23に対して、ローラ15,25よりも離れた位置で二段カム11,21に接触する。二段カム11,21をモータ7の一方側出力軸8および他方側出力軸9でそれぞれ回転駆動すると、ホロワ12,22が変位し、ベース板13,23を介してリンク機構16,26がそれぞれ駆動される。リンク機構16,26は、ステッチプレッサ3,4が取付けられているホルダ17,27および連結軸18,28を含み、ベース13,23の揺動変位に対応してステッチプレッサ3,4を変位させる。
ステッチプレッサ3,4が歯口6に進退する際に、刷毛5と干渉するおそれがあるので、カム駆動機構30で刷毛5の退避を行う。カム駆動機構30は、回転カム31でホロワ32を駆動する。回転カム31の側面には、カム溝33が形成され、ホロワ32がカム溝33内で回転カム31と係合している。回転カム31が一方側出力軸8によって回転させられると、ホロワ32はカム溝33に案内されて変位し、リンク機構34を駆動する。リンク機構34は、刷毛5を装着しているホルダ35を駆動する。
図2A〜図2Cは、図1に示す一方側駆動機構10で用いられる二段カム11の構成を示す。他方側駆動機構20で用いられる二段カム21も、基本的には同等である。図2Aは左側面、図2Bは正面断面、図2Cは右側面をそれぞれ示す。二段カム11は、モータ軸などへの固定部40とともに、少なくとも2段のカム面41,42を外周側に有する。外周面がカム面とはならない固定部40から軸孔43が2段のカム面41,42が形成されている部分を貫いて延びる。
二段カム11のカム面41,42には、図1に示すように、ローラ14,15がそれぞれ作用する。ローラ14,15間の間隔は一定である。ローラ14,15は、溝カムのように両側ではなく、外周の片側のみでカム面41,42に接触するので、二段カム41が一方向に回転する際には、ローラ14,15もそれぞれ一方向に回転すればよく、摩擦抵抗による負荷を低減することができる。また、カム面41,42は最外周の面であり、側面に溝カムが形成される回転カムのように、溝カムよりも径方向の外方まで溝カムのベースとなる部分が存在する場合よりも、径を小さくして、慣性モーメントを低下させ、負荷を軽減させることができる。
図3Aおよび図3Bは、図2A〜図2Cの二段カム11のカム面41,42の形状について示す。一対のローラ14,15間の間隔は一定であり、カム面41,42は、各ローラ14,15が接触する場合に、各ローラ14,15の回転中心と二段カム11の回転中心とが同一直線上に並ぶように形成する。さらにカム面41,42には、図3Aに示すような非作用面41a,42aと、図3Bに示すような作用面41b,42bとを設けておく。
図3Aに示すように、一対のローラ14,15が14a,15aとして示す位置にある状態で、二段カム11の回転中心である一方側出力軸8を時計回り方向に正転させる。一対のローラ14,15は、二段カム11のカム面41,42と接触しながら、14b,15bで示す位置まで、二段カム11に対して相対的に移動する。この移動の際にローラ14,15がカム面41,42にそれぞれ接触する範囲は、非作用面41a,42aとなる。ローラ14,15が非作用面41a,42aとそれぞれ接触している範囲では、各ローラ14,15の回転中心と一方側出力軸8の軸心との距離はそれぞれ一定であり、変化しない。したがって、ローラ14,15が非作用面41a,42aと接触している範囲で、一方側出力軸8が角変位して、二段カム11に対してローラ14,15が14a,15aの位置と14b,15bの位置との間の範囲内で相対的に移動しても、図1の一方側駆動機構10としては、ホロワ12は上下動しないで二段カム11が角変位するだけである。
図3Bに示すように、一対のローラ14,15が14b,15bとして示す位置にある状態で、一方側出力軸8をさらに正転させると、各ローラ14,15は、14c,15cとして示す位置まで、二段カム11に対して相対的に移動する。この移動の際にローラ14,15がカム面41,42にそれぞれ接触する区間は、作用面41b,42bとなる。ローラ14,15が作用面41b,42bとそれぞれ接触している区間では、各ローラ14,15の回転中心と一方側出力軸8の軸心との距離は変化する。したがって、ローラ14,15が作用面41b,42bと接触している区間で、一方側出力軸8が角変位して、二段カム11に対してローラ14,15が14b,15bの位置と14c,15cの位置との間の区間内で相対的に移動すると、図1の一方側駆動機構10としては、ホロワ12は上下動する。
図1に示す二段カム21も、作用面と非作用面とを有する点について、図3Aおよび図3Bに示す二段カム11と同様である。ただし、ホロワ12のローラ14,15が二段カム11の非作用面41a、42aと接触している間は、ホロワ22のローラ24,25が二段カム21の作用面と接触するように、二段カム11,21が一方側出力軸8および他方側出力軸9にそれぞれ固定される角度をずらしておく。ホロワ12のローラ14,15が二段カム11の作用面41b、42bと接触している間は、ホロワ22のローラ24,25が二段カム21の非作用面と接触するようになる。したがって、一方のステッチプレッサ3がモータ7の正転で待機する間、他方のステッチプレッサ4は上下動し、さらにモータ7の正転で、一方のステッチプレッサ3が上下動し、他方のステッチプレッサが待機するように、切換えさせることが可能となる。
図4、図5および図6は、図1の一方側駆動機構10、他方側駆動機構20およびステッチプレッサ3,4の駆動状態の一例を示す。この駆動状態では、図6に示すように、一方のステッチプレッサ3は不作用で、他方のステッチプレッサ4が作用する。このような状態は、基準状態として設定され、この基準状態は、図4および図5に示すように、近接センサ50が一方側出力軸8に取付けられている検出片51を検出し、近接センサ55が他方側出力軸9に取付けられている検出片56を検出する状態として規定される。図4に示すように、二段カム11に対して、ホロワ12は下側のローラ15が一方側出力軸8最も接近し、上側のローラ14が一方側出力軸8から最も離れた位置となる。ホロワ12のこの位置への移動は、ベース13を介してリンク部材52からホルダ17に伝達され、ステッチプレッサ3を図6の上方に位置させる。図5に示すように、二段カム21に対して、ホロワ22は上側のローラ24が他方側出力軸9に最も接近し、下側のローラ25が他方側出力軸9から最も離れた位置となる。ホロワ22のこの位置への移動は、ベース23を介してリンク部材57からホルダ27に伝達され、ステッチプレッサ4を図6の下方に位置させる。
図6に示すように、ステッチプレッサ3,4に立体的な移動軌跡を与えるために、カム板60,65がそれぞれ用いられる。カム板60,65には、カム溝61,66がそれぞれ形成され、ホルダ17,27から延びるホロワ62,67がそれぞれ係合している。なお、カム溝61,66は、実線と破線とで示すように、上端側で少し異なる。
図7は、図4〜図6に対応するカム駆動機構30の状態を示す。回転カム31のカム溝33によって案内されるホロワ32は、一方側出力軸8に接近する位置となっている。この位置では、リンク機構34を介して、刷毛5は下方に下がる状態となる。
図8は、図4〜図7に示される状態よりも、一方側出力軸8および他方側出力軸9を回転させ、ステッチプレッサ4を引き上げる状態を示す。ステッチプレッサ4が狭い歯口を通過するので、干渉しないように、刷毛5は上げて退避させる。
図9は、ステッチプレッサ4を退避させている状態を示す。図9において、ステッチプレッサ3も退避している。両方のステッチプレッサ3,4が同じ位置で退避すると干渉するので、前述のようにカム溝61,66の形状を上端側で異ならせ、ステッチプレッサ3,4の退避位置を少しずらせるようにしている。刷毛5は、退避を終了して、下方の位置に戻る。モータ7をさらに回転させれば、ステッチプレッサ3を歯口6に進出させ、その際に刷毛5を退避させることができる。
以上のように、一方側駆動機構10および他方側駆動機構20では、径方向の外周に形成されるカム面41,42を、軸方向に2段有する回転カムである二段カム11,21と、回転カムの各段のカム面41,42にそれぞれ接触して追従し、一定の間隔を保って保持される一対のローラ14,15;24,25とを有するので、回転カムの径を小さくして慣性負荷を軽減し、一対のローラ14,15;24,25を外周のカム面41,42に両側からそれぞれ接触させて、カム面41,42に追従させる際の負荷も軽減して、モータ7に必要な出力を低減し、モータ7の小型化を図ることができる。
以上のように、一方側駆動ユニットおよび他方側駆動ユニットは、一対の部材のいずれか一方を、歯口6に進退する揺動変位が可能なように支持するリンク機構と、リンク機構の一部を、モータ7の正転または逆転で揺動変位させ、リンク機構に支持されて行う一対の部材のいずれか一方の揺動変位に変換させるので、小型化を図ることができる。
なお、第3の部材としては、刷毛5ばかりではなく、ヤーンガイドまたは可動シンカなどにも適用することができる。ただし、ヤーンガイドおよび可動シンカは、針床側に備えられ、キャリッジ2に搭載されるカム板の溝カムで案内されて歯口6に作用するものである。このようなヤーンガイドおよび可動シンカに対しては、カム板を摺動変位させて、ステッチプレッサ3,4が歯口6に進退する際に、退避させるようにすればよい。カム板の摺動変位のための構成は、たとえば前述の特公平6−72347号公報に開示されているものを利用することができる。
本発明は、その精神または主要な特徴から逸脱することなく、他のいろいろな形態で実施できる。したがって、前述の実施形態はあらゆる点で単なる例示に過ぎず、本発明の範囲は特許請求の範囲に示すものであって、明細書本文には何ら拘束されない。さらに、特許請求の範囲に属する変形や変更は全て本発明の範囲内のものである。
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 shows a schematic configuration of a drive unit 1 as an embodiment of the present invention. The drive unit 1 is mounted on a carriage 2 that reciprocates along the needle bed of the flat knitting machine, and functions as a carriage mounting unit of the flat knitting machine. The carriage 2 performs selective driving for knitting the knitted fabric by moving the knitting needle back and forth from the needle bed. The drive unit 1 includes at least three members that move forward and backward independently of the knitting needle, including a pair of members that can be switched according to the traveling direction of the carriage 2. That is, the pair of stitch pressers 3 and 4, that is, one stitch presser 3 and the other stitch presser 4 are switched between each other as the carriage 2 moves in the left-right direction in the figure. As the third member, a brush 5 that opens the spatula is also used when a spatula needle is used as the knitting needle. The three members of the pair of stitch pressers 3 and 4 and the brush 5 advance and retract to the mouth 6 where the knitting needle is advanced and retracted to perform knitting of the knitted fabric, and perform an auxiliary action of the knitted fabric.
The drive unit 1 is a carriage mounting unit of a flat knitting machine that can drive each member with a single motor 7. The motor 7 is arranged so that the output shaft protrudes on both sides in the direction of the motor shaft 7 a as the one side output shaft 8 and the other side output shaft 9, and the motor shaft 7 a direction is parallel to the reciprocating direction of the carriage 2. . On one side output shaft 8 of the motor 7, one side drive mechanism that drives one of the stitch pressers 3 by converting the rotational motion into a swinging motion so as to advance into the tooth opening 6 by rotating the motor 7 in one direction. 10 is arranged. On the other side output shaft 9 of the motor 7, the other side drive mechanism that drives the other stitch presser 4 by converting the rotational motion into a swinging motion so as to advance to the tooth opening 6 by rotating in the other direction of the motor 7. 20 is arranged. A member different from the pair of stitch pressers 3 and 4 by the rotational movement of the motor 7 adjacent to either the one side drive mechanism 10 or the other side drive mechanism 20 (one side drive mechanism 10 in FIG. 1). A cam drive mechanism 30 is disposed as another member drive mechanism for moving a brush 5 forward and backward to the tooth opening 6 so as to avoid interference with the pair of stitch pressers 3 and 4. With a single motor 7, at least three of the stitch pressers 3 and 4 as a pair of members and the brush 5 as another member are moved forward and backward by the rotation of the motor 7. Since the groove cam plate that reciprocates in the reciprocating direction of the carriage 2 is not included in the driving, the carriage mounting unit can be downsized even if it has many functions.
The one side drive mechanism 10 includes a two-stage cam 11, and the other side drive mechanism 20 includes a two-stage cam 21. The two-stage cams 11 and 21 have a cam surface formed on the outer periphery over two stages, and the cam surfaces are sandwiched between rollers 14 and 15; 24 and 25 standing at regular intervals from the bases 13 and 23 of the followers 12 and 22. Then, the followers 12 and 22 are caused to follow. Since the cam surfaces are formed in two steps, the rollers 14 and 24 are in contact with the two-stage cams 11 and 21 at positions farther from the rollers 15 and 25 than the bases 13 and 23. When the two-stage cams 11 and 21 are rotationally driven by the one side output shaft 8 and the other side output shaft 9 of the motor 7, the followers 12 and 22 are displaced, and the link mechanisms 16 and 26 are respectively connected via the base plates 13 and 23. Driven. The link mechanisms 16 and 26 include holders 17 and 27 and connecting shafts 18 and 28 to which the stitch pressers 3 and 4 are attached. The link mechanisms 16 and 26 displace the stitch pressers 3 and 4 in response to the rocking displacement of the bases 13 and 23. .
When the stitch pressers 3 and 4 advance and retreat to and from the tooth opening 6, the brush 5 may be retracted by the cam drive mechanism 30 because there is a possibility of interfering with the brush 5. The cam drive mechanism 30 drives the follower 32 with the rotating cam 31. A cam groove 33 is formed on the side surface of the rotating cam 31, and the follower 32 is engaged with the rotating cam 31 in the cam groove 33. When the rotating cam 31 is rotated by the one-side output shaft 8, the follower 32 is guided and displaced by the cam groove 33 to drive the link mechanism 34. The link mechanism 34 drives the holder 35 to which the brush 5 is attached.
2A to 2C show the configuration of the two-stage cam 11 used in the one-side drive mechanism 10 shown in FIG. The two-stage cam 21 used in the other drive mechanism 20 is basically the same. 2A shows the left side, FIG. 2B shows the front cross section, and FIG. 2C shows the right side. The two-stage cam 11 has at least two-stage cam surfaces 41 and 42 on the outer peripheral side together with a fixing portion 40 to the motor shaft or the like. A shaft hole 43 extends from a fixed portion 40 whose outer peripheral surface does not become a cam surface through a portion where two-stage cam surfaces 41 and 42 are formed.
Rollers 14 and 15 act on the cam surfaces 41 and 42 of the two-stage cam 11 as shown in FIG. The distance between the rollers 14 and 15 is constant. Since the rollers 14 and 15 contact the cam surfaces 41 and 42 only on one side of the outer periphery, not on both sides like a groove cam, when the two-stage cam 41 rotates in one direction, the rollers 14 and 15 also respectively It is sufficient to rotate in one direction, and the load due to frictional resistance can be reduced. In addition, the cam surfaces 41 and 42 are the outermost peripheral surfaces, and there is a portion that becomes the base of the groove cam to the outside in the radial direction from the groove cam, such as a rotating cam in which the groove cam is formed on the side surface. The diameter can be made smaller, the moment of inertia can be reduced, and the load can be reduced.
3A and 3B show the shapes of the cam surfaces 41 and 42 of the two-stage cam 11 shown in FIGS. 2A to 2C. The distance between the pair of rollers 14 and 15 is constant, and the cam surfaces 41 and 42 have a rotation center between the rollers 14 and 15 and a rotation center of the two-stage cam 11 when the rollers 14 and 15 come into contact with each other. It forms so that it may align on the same straight line. Furthermore, the cam surfaces 41 and 42 are provided with non-operation surfaces 41a and 42a as shown in FIG. 3A and operation surfaces 41b and 42b as shown in FIG. 3B.
As shown in FIG. 3A, in a state where the pair of rollers 14 and 15 are at positions shown as 14a and 15a, the one-side output shaft 8 that is the rotation center of the two-stage cam 11 is rotated forward in the clockwise direction. The pair of rollers 14 and 15 moves relative to the two-stage cam 11 to the positions indicated by 14b and 15b while contacting the cam surfaces 41 and 42 of the two-stage cam 11. The areas where the rollers 14 and 15 come into contact with the cam surfaces 41 and 42 during this movement are non-working surfaces 41a and 42a. In the range where the rollers 14 and 15 are in contact with the non-operation surfaces 41a and 42a, the distances between the rotation centers of the rollers 14 and 15 and the axis of the one-side output shaft 8 are constant and do not change. Therefore, in a range where the rollers 14 and 15 are in contact with the non-operation surfaces 41a and 42a, the one-side output shaft 8 is angularly displaced, so that the rollers 14 and 15 are positioned at the positions 14a and 15a with respect to the two-stage cam 11. Even if it moves relatively within the range between the positions 14b and 15b, as the one-side drive mechanism 10 in FIG. 1, the follower 12 does not move up and down and the two-stage cam 11 is merely angularly displaced.
As shown in FIG. 3B, when the one-side output shaft 8 is further rotated forward in a state where the pair of rollers 14 and 15 are in the positions indicated as 14b and 15b, the rollers 14 and 15 are indicated as positions 14c and 15c. Until the two-stage cam 11 moves. The sections where the rollers 14 and 15 come into contact with the cam surfaces 41 and 42 during this movement are the operation surfaces 41b and 42b. In the section where the rollers 14 and 15 are in contact with the working surfaces 41b and 42b, the distance between the rotation center of each of the rollers 14 and 15 and the axis of the one-side output shaft 8 changes. Therefore, in the section where the rollers 14 and 15 are in contact with the working surfaces 41 b and 42 b, the one-side output shaft 8 is angularly displaced, so that the rollers 14 and 15 are positioned 14 c and 14 c relative to the two-stage cam 11. , 15c, the follower 12 moves up and down as the one-side drive mechanism 10 in FIG.
The two-stage cam 21 shown in FIG. 1 is the same as the two-stage cam 11 shown in FIGS. 3A and 3B in that it has a working surface and a non-working surface. However, while the rollers 14 and 15 of the follower 12 are in contact with the non-operation surfaces 41 a and 42 a of the two-stage cam 11, the rollers 24 and 25 of the follower 22 are in contact with the operation surface of the two-stage cam 21. The angles at which the two-stage cams 11 and 21 are fixed to the one-side output shaft 8 and the other-side output shaft 9 are shifted. While the rollers 14 and 15 of the follower 12 are in contact with the operation surfaces 41 b and 42 b of the two-stage cam 11, the rollers 24 and 25 of the follower 22 come into contact with the non-operation surface of the two-stage cam 21. Therefore, while one stitch presser 3 waits for normal rotation of the motor 7, the other stitch presser 4 moves up and down, and when the motor 7 rotates forward, one stitch presser 3 moves up and down, and the other stitch presser 3 Can be switched to wait.
4, 5, and 6 show an example of driving states of the one side driving mechanism 10, the other side driving mechanism 20, and the stitch pressers 3 and 4 of FIG. 1. In this driving state, as shown in FIG. 6, one stitch presser 3 is inactive and the other stitch presser 4 is in effect. Such a state is set as a reference state. In this reference state, as shown in FIGS. 4 and 5, the proximity sensor 50 detects the detection piece 51 attached to the one-side output shaft 8, and the proximity sensor 55 is defined as a state in which the detection piece 56 attached to the other output shaft 9 is detected. As shown in FIG. 4, with respect to the two-stage cam 11, in the follower 12, the lower roller 15 is closest to the one side output shaft 8, and the upper roller 14 is farthest from the one side output shaft 8. . The movement of the follower 12 to this position is transmitted from the link member 52 to the holder 17 through the base 13, and the stitch presser 3 is positioned above FIG. As shown in FIG. 5, the follower 22 has a position in which the upper roller 24 is closest to the other output shaft 9 and the lower roller 25 is farthest from the other output shaft 9 with respect to the two-stage cam 21. Become. The movement of the follower 22 to this position is transmitted from the link member 57 to the holder 27 via the base 23, and the stitch presser 4 is positioned below in FIG.
As shown in FIG. 6, cam plates 60 and 65 are used to give the three-dimensional movement trajectories to the stitch pressers 3 and 4, respectively. Cam grooves 61 and 66 are formed in the cam plates 60 and 65, respectively, and followers 62 and 67 extending from the holders 17 and 27 are engaged. The cam grooves 61 and 66 are slightly different on the upper end side as indicated by the solid line and the broken line.
FIG. 7 shows the state of the cam drive mechanism 30 corresponding to FIGS. The follower 32 guided by the cam groove 33 of the rotating cam 31 is positioned close to the one-side output shaft 8. At this position, the brush 5 is lowered downward via the link mechanism 34.
FIG. 8 shows a state in which the one-side output shaft 8 and the other-side output shaft 9 are rotated and the stitch presser 4 is pulled up as compared with the states shown in FIGS. Since the stitch presser 4 passes through the narrow mouth, the brush 5 is raised and retracted so as not to interfere.
FIG. 9 shows a state in which the stitch presser 4 is retracted. In FIG. 9, the stitch presser 3 is also retracted. If both the stitch pressers 3 and 4 are retracted at the same position, they interfere with each other. As described above, the cam grooves 61 and 66 have different shapes on the upper end side so that the retract positions of the stitch pressers 3 and 4 are slightly shifted. Yes. The brush 5 finishes evacuation and returns to a lower position. If the motor 7 is further rotated, the stitch presser 3 can be advanced to the tooth opening 6 and the brush 5 can be retracted at that time.
As described above, in the one-side drive mechanism 10 and the other-side drive mechanism 20, the two-stage cams 11 and 21, which are rotary cams having two cam surfaces 41 and 42 formed on the outer circumference in the radial direction in the axial direction, , Each of the rotating cams has a pair of rollers 14 and 15; 24 and 25 which are held in contact with each other and are held at a certain interval, thereby reducing the diameter of the rotating cam. In this case, the inertia load is reduced, the load when the pair of rollers 14, 15; The output required for the motor 7 can be reduced, and the motor 7 can be downsized.
As described above, the one-side drive unit and the other-side drive unit each support one of a pair of members so as to be able to swing and move back and forth in the tooth opening 6 and a part of the link mechanism. Is oscillated and displaced by normal rotation or reverse rotation of the motor 7 and converted into one of the pair of oscillating displacements supported by the link mechanism, so that the size can be reduced.
Note that the third member can be applied not only to the brush 5 but also to a yarn guide or a movable sinker. However, the yarn guide and the movable sinker are provided on the needle bed side, and are guided by a groove cam of a cam plate mounted on the carriage 2 to act on the tooth opening 6. For such a yarn guide and movable sinker, the cam plate may be slid and displaced so that the stitch pressers 3 and 4 retract when the stitch pressers 3 and 4 advance and retract. As the configuration for the sliding displacement of the cam plate, for example, the one disclosed in the aforementioned Japanese Patent Publication No. 6-72347 can be used.
The present invention can be implemented in various other forms without departing from the spirit or main features thereof. Therefore, the above-described embodiment is merely an example in all respects, and the scope of the present invention is shown in the claims, and is not restricted by the text of the specification. Further, all modifications and changes belonging to the scope of the claims are within the scope of the present invention.

According to the present invention, there is provided a flat knitting machine capable of driving each member with a single motor, including at least three members including a pair of members that can be switched according to the traveling direction of the carriage. Even if the carriage mounting unit is realized without including a grooved cam plate that reciprocates in the reciprocating direction of the carriage and has many functions, the carriage mounting unit can be downsized.
Further, according to the present invention, the one side drive unit and the other side drive unit cause the oscillation displacement of one of the pair of members performed by being supported by the link mechanism by rotating the output shaft of the motor forward or backward. Therefore, downsizing can be achieved. In addition, since the outer peripheral surface of the rotating cam is the cam surface, the load is reduced when the diameter is reduced to reduce the inertia load, and the pair of rollers are brought into contact with the outer cam surface from both sides to follow the cam surface. This can reduce the output required for the motor and reduce the size of the motor.
According to the invention, the two-stage cam surface of the rotating cam has the rotation center of each roller of the pair of rollers and the rotation center of the rotating cam aligned on the same straight line, and the rotation center of each roller and the rotation cam.
