Abstract

潤滑油が吸着面に降りてくることが原因で生じる選針ミスを防止することができる選針アクチュエータおよび横編機を提供する。選針アクチュエータ31では、吸着面32に、溝33a,33b,33cが設けられる。溝33a,33b,33cは、選針アクチュエータ31を選針機構に含むように搭載するキャリッジが針床に沿って往復走行する際に、吸着面32に対して編針のセレクタの接極部が相対的に移動する図の横方向で、吸着面33の両端間に延びるように設けられる。このような溝33a,33b,33cを設ける選針アクチュエータ31を横編機で吸着面に溝の無い選針アクチュエータに代えて用いることによって、潤滑油を掻き出すことができ、潤滑油の付着に由来する選針ミスの低減を図ることができる。Provided are a needle selection actuator and a flat knitting machine capable of preventing a needle selection error caused by the fact that lubricating oil falls on an adsorption surface. In the needle selection actuator 31, grooves 33a, 33b, and 33c are provided on the suction surface 32. The grooves 33a, 33b, and 33c are arranged such that the armature portion of the selector of the knitting needle is relative to the suction surface 32 when a carriage that includes the needle selection actuator 31 in the needle selection mechanism reciprocates along the needle bed. Are provided so as to extend between both ends of the suction surface 33 in the horizontal direction of the drawing. By using the needle selection actuator 31 provided with such grooves 33a, 33b, and 33c in place of the needle selection actuator having no groove on the suction surface with a flat knitting machine, the lubricating oil can be scraped out, resulting from the adhesion of the lubricating oil. It is possible to reduce needle selection mistakes.

Description

本発明は、横編機で選針を行うためにキャリッジに搭載される選針アクチュエータ、およびそのような選針アクチュエータを備える横編機に関する。   The present invention relates to a needle selection actuator mounted on a carriage in order to perform needle selection with a flat knitting machine, and a flat knitting machine including such a needle selection actuator.

従来から、横編機では、針床に多数配置されている編針に対し、針床に沿って走行するキャリッジに搭載される選針機構とカム機構とで選針および編成駆動を行って、編地を編成している。選針機構として、電磁的な吸着を利用する選針アクチュエータを用いると、可動部分を有しないで高速な動作が可能になる(たとえば、特許文献1および特許文献2参照。)。   Conventionally, in a flat knitting machine, needle selection and knitting drive are performed by a needle selection mechanism and a cam mechanism mounted on a carriage that runs along the needle bed, with respect to a large number of knitting needles arranged on the needle bed. The ground is organized. When a needle selection actuator that uses electromagnetic attraction is used as the needle selection mechanism, high-speed operation is possible without a movable part (see, for example, Patent Document 1 and Patent Document 2).

図4は、特許文献2と同様な選針機構を備える横編機1の概略的な構成を示す。横編機1には、紙面に垂直な方向に延びる板状の針床2が備えられる。針床2には、延びる方向である長手方向に対しては垂直となり、紙面上では横方向に延びる溝が一定のピッチで形成される。針床2の長手方向には、キャリッジ3が往復走行する。針床2の溝には、ニードルプレート4が挿入される。針床2に全てのニードルプレート4が挿入されると、プレート締付ワイヤ5で締付けられ、固定される。このような針床2は、歯口6を挟んで対をなすように対向して配置される。針床2の歯口6側には、シンカープレート7が装着され、シンカー固定ワイヤ8で固定される。シンカープレート7の歯口6側先端付近には、歯口ワイヤ9が挿通される。   FIG. 4 shows a schematic configuration of a flat knitting machine 1 having a needle selection mechanism similar to that of Patent Document 2. The flat knitting machine 1 is provided with a plate-like needle bed 2 extending in a direction perpendicular to the paper surface. In the needle bed 2, grooves that are perpendicular to the longitudinal direction that is the extending direction and extend in the lateral direction on the paper surface are formed at a constant pitch. In the longitudinal direction of the needle bed 2, the carriage 3 reciprocates. A needle plate 4 is inserted into the groove of the needle bed 2. When all the needle plates 4 are inserted into the needle bed 2, the needle plates 4 are fastened and fixed by the plate fastening wires 5. Such needle beds 2 are arranged to face each other so as to form a pair with the tooth opening 6 interposed therebetween. A sinker plate 7 is mounted on the side of the mouth 6 of the needle bed 2 and is fixed by a sinker fixing wire 8. A tooth opening wire 9 is inserted near the tip of the sinker plate 7 on the side of the mouth opening 6.

横編機1では、機械装置としての通常使用時の正面から見て、歯口6の前後に針床2が配置される。各針床2は歯口6に臨む側が高く、歯口6から離れると低くなる。歯口6の側方から見ると、前後の針床2は逆V字状に傾斜している。ただし、図面上では、説明の便宜上、一方の針床2のみを、ほぼ水平な姿勢として記載する。以下、歯口6に接近する方向を前方、歯口6から遠ざかる方向を後方として前後方向を記載する。また、針床2の底面側を下方、表面側を上方として、上下方向を記載する。   In the flat knitting machine 1, the needle bed 2 is arranged in front of and behind the tooth opening 6 when viewed from the front during normal use as a mechanical device. Each needle bed 2 is high on the side facing the mouth 6, and becomes lower when it is away from the mouth 6. When viewed from the side of the mouth 6, the front and back needle beds 2 are inclined in an inverted V shape. However, in the drawing, for convenience of explanation, only one needle bed 2 is described as a substantially horizontal posture. Hereinafter, the front-rear direction is described with the direction approaching the tooth mouth 6 as the front and the direction away from the tooth mouth 6 as the rear. The vertical direction is described with the bottom side of the needle bed 2 being the lower side and the front side being the upper side.

針床2上で隣接するニードルプレート4間には、針溝が形成される。各針溝内には、編針10が収容される。編針10は、図の左右方向、すなわち歯口6を基準とする前後方向に摺動変位しながら、編地の編成を行う。編針10は、ニードル11、ニードルジャック12、セレクトジャック13およびセレクタ14を組合せて構成される。ニードル11は、歯口6側への進退と、先端のフック11aのべら11bによる開閉とを組合わせて、編地の編成動作を行う。ニードル11の中間よりも後方の位置には、係合部11cが設けられる。   A needle groove is formed between adjacent needle plates 4 on the needle bed 2. A knitting needle 10 is accommodated in each needle groove. The knitting needle 10 performs knitting of the knitted fabric while sliding and displacing in the left-right direction in the figure, that is, the front-rear direction with reference to the tooth opening 6. The knitting needle 10 is configured by combining a needle 11, a needle jack 12, a select jack 13 and a selector 14. The needle 11 performs a knitting operation of the knitted fabric by combining advancing and retreating toward the tooth opening 6 side and opening and closing by the lever 11b of the hook 11a at the tip. An engaging portion 11 c is provided at a position behind the middle of the needle 11.

ニードル11の係合部11cには、ニードルジャック12の先端部12aが係合する。ニードルジャック12の中間にはバット12bが設けられ、バット12bの周辺から尾端部12cにかけての部分は、針溝内でバット12bが上方に浮上するように付勢するばねとして機能する。ニードルジャック12のバット12bと尾端部12cとの間は、セレクトジャック13の先端押圧部13aで押圧される。   The tip portion 12 a of the needle jack 12 is engaged with the engaging portion 11 c of the needle 11. A bat 12b is provided in the middle of the needle jack 12, and a portion from the periphery of the bat 12b to the tail end portion 12c functions as a spring that biases the bat 12b to rise upward in the needle groove. Between the butt 12b and the tail end portion 12c of the needle jack 12, the tip pressing portion 13a of the select jack 13 is pressed.

セレクトジャック13は、受圧バット13bに、キャリッジ3に搭載されるカム機構のプレッサからの押圧を受ける。この押圧を上方から受けると、セレクトジャック13は、先端押圧部13aを介してニードルジャック12を押圧し、ニードルジャック12のバット12bが針溝から突出しないように、押え込む。セレクトジャック13の受圧バット13bよりも少し後方には、突起13cが設けられる。セレクトジャック13の後部には、二股部13dが形成されている。セレクトジャック13の突起13cは、セレクタ14からの前進駆動を受ける。セレクトジャック13の受圧バット13bの側部は、カム機構からの後退駆動を受ける。   The select jack 13 receives a pressure from the presser of the cam mechanism mounted on the carriage 3 by the pressure receiving bat 13b. When this pressing is received from above, the select jack 13 presses the needle jack 12 via the tip pressing portion 13a and presses the butt 12b of the needle jack 12 so that it does not protrude from the needle groove. A protrusion 13c is provided slightly behind the pressure receiving bat 13b of the select jack 13. A bifurcated portion 13 d is formed at the rear portion of the select jack 13. The protrusion 13 c of the select jack 13 receives forward drive from the selector 14. The side portion of the pressure-receiving butt 13b of the select jack 13 receives a backward drive from the cam mechanism.

セレクタ14は、前バット14a、中バット14bおよび後バット14cを有する。前バット14aは、セレクタ14が選針機構の作用を受ける際の揺動支点となる。中バット14bは、後方に変位する際に駆動される。後バット14cは、前方に変位する際に駆動される。前方に変位する際に、先端部14dがセレクトジャック13の突起13cに当接すると、セレクタ14がセレクトジャック13を押して歯口6側に変位させる。セレクタ14の前バット14aよりも後方は、二股状に分れており、下側は弾性レッグ14eとなって、上側が浮上するように付勢している。セレクタ14の後方で二股状に分れている上側には、中バット14bおよび後バット14cが設けられ、尾端は接極部14fとなっている。   The selector 14 has a front bat 14a, a middle bat 14b, and a rear bat 14c. The front butt 14a serves as a swing fulcrum when the selector 14 receives the action of the needle selection mechanism. The middle bat 14b is driven when displaced backward. The rear bat 14c is driven when displaced forward. When the front end portion 14d comes into contact with the protrusion 13c of the select jack 13 during the forward displacement, the selector 14 pushes the select jack 13 and displaces it toward the tooth opening 6 side. The rear side of the selector 14 with respect to the front bat 14a is bifurcated, and the lower side is an elastic leg 14e, which is biased so that the upper side is lifted. An intermediate butt 14b and a rear butt 14c are provided on the upper side of the selector 14 which is divided into a bifurcated shape, and the tail end is a contact portion 14f.

ニードルプレート4には、紙面に垂直な方向に、ニードル押え板15、帯金16a,16bおよびワイヤ17a,17b,17cが挿通されている。ニードル押え板15は、ニードル11が針溝から飛出さないように、ニードル11を上方から規制する。帯金16a,16bは、セレクタ14が針溝から飛出さないように押える。ワイヤ17a,17b,17cは、ストッパなどとして機能する。   The needle plate 4, the straps 16 a and 16 b, and the wires 17 a, 17 b and 17 c are inserted through the needle plate 4 in a direction perpendicular to the paper surface. The needle pressing plate 15 regulates the needle 11 from above so that the needle 11 does not fly out of the needle groove. The straps 16a and 16b are pressed so that the selector 14 does not jump out of the needle groove. The wires 17a, 17b, and 17c function as stoppers and the like.

針床2に多数配列される編針10は、キャリッジ3に搭載される選針機構で選択され、カム機構で編成駆動される。キャリッジ3のケース20の底面には、カム機構が設けられるカムプレート21と、選針機構が設けられるセレクタプレート22とが配置されて、針床2の表面に臨む。ただし、カム機構と選針機構との図示は省略する。セレクタプレート22の後端には、ブラケット23を介して選針アクチュエータ24が取付けられている。   A large number of knitting needles 10 arranged on the needle bed 2 are selected by a needle selection mechanism mounted on the carriage 3 and are knitted and driven by a cam mechanism. A cam plate 21 provided with a cam mechanism and a selector plate 22 provided with a needle selection mechanism are disposed on the bottom surface of the case 20 of the carriage 3 so as to face the surface of the needle bed 2. However, illustration of the cam mechanism and the needle selection mechanism is omitted. A needle selection actuator 24 is attached to the rear end of the selector plate 22 via a bracket 23.

選針アクチュエータ24の表面には吸着面25が形成される。吸着面25は、セレクタ14の接極部14fに臨む。吸着面25には、複数の磁極25a,25bが配置される。実際の吸着面25は、端部に磁極25a,25bが形成される磁性材間に非磁性材25cとして合成樹脂が充填され、磁性材を固着させた後、表面を平坦化するように製造している。   An adsorption surface 25 is formed on the surface of the needle selection actuator 24. The suction surface 25 faces the contact portion 14 f of the selector 14. A plurality of magnetic poles 25 a and 25 b are arranged on the attracting surface 25. The actual attracting surface 25 is manufactured so that a synthetic resin is filled as a non-magnetic material 25c between magnetic materials on which magnetic poles 25a and 25b are formed at end portions, and after the magnetic material is fixed, the surface is flattened. ing.

図5は、選針アクチュエータ24での吸着面25の構成を示す(たとえば、特許文献3参照。)。特許文献3では、磁極25a,25bと非磁性材25cとを有する2つの制御吸着部を、磁極26a,26b,26cと非磁性材26d,26eとを有する3つの非制御吸着部で挟むように配置している。制御吸着部には、永久磁石とともにコイル27a,27bから発生する磁束も供給される。コイル27a,27bへの通電で永久磁石からの磁束を打消し、制御吸着部は、吸着力を弱くする制御が可能である。非制御吸着部は、永久磁石からの磁束のみが供給される。図4に示すキャリッジ3のセレクタプレート22には、セレクタ14の尾部を上方から押圧し、接極部14fを非制御吸着部に接触させて吸着させるプレッサが設けられている。制御吸着部では、各編針10毎に、セレクタ14の接極部14fを吸着し続けるか吸着を解除するかの選択を行う。このため、図では横方向に示される制御吸着部の長さは編針10の1ピッチ分程度で短く、非制御吸着部との間隔も狭くなってしまうので、非制御吸着部からの磁束の漏れがあると、制御吸着部での吸着解除制御に影響が生じる。   FIG. 5 shows a configuration of the suction surface 25 in the needle selection actuator 24 (see, for example, Patent Document 3). In Patent Document 3, two control attracting portions having magnetic poles 25a and 25b and a nonmagnetic material 25c are sandwiched between three noncontrolling attracting portions having magnetic poles 26a, 26b and 26c and nonmagnetic materials 26d and 26e. It is arranged. Magnetic flux generated from the coils 27a and 27b is also supplied to the control attracting portion together with the permanent magnet. The energization of the coils 27a and 27b cancels the magnetic flux from the permanent magnet, and the control attracting unit can control to weaken the attracting force. Only the magnetic flux from the permanent magnet is supplied to the non-controlled attracting unit. The selector plate 22 of the carriage 3 shown in FIG. 4 is provided with a presser that presses the tail portion of the selector 14 from above and causes the contact portion 14f to come into contact with the non-controlling suction portion. The control adsorption unit selects for each knitting needle 10 whether to continue attracting the contact portion 14f of the selector 14 or to cancel the adsorption. For this reason, the length of the control suction portion shown in the horizontal direction in the figure is as short as about one pitch of the knitting needle 10 and the interval with the non-control suction portion is also narrowed. Therefore, leakage of magnetic flux from the non-control suction portion If there is, it will affect the suction release control in the control suction unit.

特許文献3では、非制御吸着部からの漏れ磁束が制御吸着部での制御に影響しにくくなるようにするため、磁極26a,26b,26cの配置を磁極25a,25bの配置とずらすようにしている。銅板28は、制御吸着部と非制御吸着部との間に、漏れ磁束を抑制して各吸着部で独立した磁気回路を構成させるために設けられている。吸着面25には、図で縦方向となる幅方向の両側にプロテクタ29a,29bが配置される。選針アクチュエータ24の全体は、ケース30に収容される。   In Patent Document 3, the magnetic fluxes 26a, 26b, and 26c are shifted from the magnetic poles 25a and 25b so that the leakage magnetic flux from the non-controlled suction portion is less likely to affect the control of the control suction portion. Yes. The copper plate 28 is provided between the control attracting part and the non-control attracting part in order to suppress the leakage magnetic flux and configure an independent magnetic circuit in each attracting part. On the suction surface 25, protectors 29a and 29b are arranged on both sides in the width direction, which is the vertical direction in the figure. The entire needle selection actuator 24 is accommodated in the case 30.

選針アクチュエータ24の吸着面25での漏れ磁束対策としては、図5に示すように制御吸着部での磁極25a,25bの配置と非制御吸着部での磁極の配置とをずらす方法とともに、ずらさないで、磁気抵抗の配分で漏れを減らす方法もある(たとえば、特許文献4参照。)。

図4に示すような編針10では、ニードルジャック12のバット12bにキャリッジ3に搭載されるカム機構が作用して編成動作が行われる。編成動作を円滑に行うために、バット12b付近には潤滑油が供給される。針床2は、歯口6側が高く、選針アクチュエータ24側が低くなるように傾斜しているので、バット12b付近に供給された潤滑油は、針溝内を流下して、セレクタ14の接極部14fや選針アクチュエータ24の吸着面25にまで降りてくる。接極部14fや吸着面25に潤滑油が溜ると、横編機1が設置されている環境によっては、潤滑油で接極部14fと吸着面25との間が接着される状態となり、通電しても制御吸着部で吸着を解除することができない選針ミスを起こす可能性がある。   In the knitting needle 10 as shown in FIG. 4, the knitting operation is performed by the cam mechanism mounted on the carriage 3 acting on the bat 12 b of the needle jack 12. In order to perform the knitting operation smoothly, lubricating oil is supplied in the vicinity of the bat 12b. Since the needle bed 2 is inclined so that the tooth opening 6 side is high and the needle selection actuator 24 side is low, the lubricating oil supplied to the vicinity of the butt 12b flows down in the needle groove, and the armature of the selector 14 It descends to the suction surface 25 of the portion 14f and the needle selection actuator 24. When lubricating oil accumulates on the armature portion 14f and the suction surface 25, depending on the environment in which the flat knitting machine 1 is installed, the armature portion 14f and the suction surface 25 are bonded to each other by the lubricating oil. Even in this case, there is a possibility of making a needle selection error in which the suction cannot be released by the control suction unit.

特許文献1に開示されている構成は、選針アクチュエータ24に相当する部分をキャリッジ3側に設けるので、潤滑油による吸着の問題は生じないと考えられる。しかしながら、接極部14fに相当する部分を吸着面25に強制的に接触させるプレッサもキャリッジ3側に設ける必要がある。セレクタ14に相当する部材では、プレッサで押圧する部分と接極部14fに相当する部分との中間に揺動支点を設けるので、セレクタ14に相当する部材の前後方向の長さが長くなり、選針機構が大形化してしまう。   In the configuration disclosed in Patent Document 1, since a portion corresponding to the needle selection actuator 24 is provided on the carriage 3 side, it is considered that the problem of adsorption by the lubricating oil does not occur. However, a presser for forcibly contacting the portion corresponding to the contact portion 14f with the suction surface 25 also needs to be provided on the carriage 3 side. In the member corresponding to the selector 14, the swing fulcrum is provided between the portion pressed by the presser and the portion corresponding to the armature portion 14 f, so that the length of the member corresponding to the selector 14 increases in the front-rear direction. The needle mechanism becomes large.

本発明の目的は、潤滑油が吸着面に降りてくることが原因で生じる選針ミスを防止することができる選針アクチュエータおよび横編機を提供することである。   An object of the present invention is to provide a needle selection actuator and a flat knitting machine that can prevent a needle selection error caused by the lubricant falling on the adsorption surface.

Two magnetic poles in which the groove is formed are provided.

本発明によれば、選針アクチュエータは、横編機の針床に沿って走行するキャリッジに搭載され、吸着面に、キャリッジの走行方向の両端間を貫通する溝が少なくとも1つの磁極を通るように形成される。このように、磁極に溝を設けると吸着力が低下する可能性があると考えられるので、従来、磁極に溝を設けるような発想は存在しない。本件発明者は、吸着力の低下を許容範囲内に留めるような小さい溝幅でも、選針ミスの防止に効果があることを見出している。すなわち、走行方向の溝が形成されるので、選針アクチュエータの吸着面に潤滑油などが降りてきても、編針のセレクタの接極部を吸着して相対的に摺動させる際に、潤滑油などを溝に沿って掻き出すことができ、選針ミスを防ぐことができる。   According to the present invention, the needle selection actuator is mounted on a carriage that runs along the needle bed of the flat knitting machine, and a groove that passes through both ends of the carriage in the running direction passes through at least one magnetic pole on the suction surface. Formed. As described above, it is considered that if the groove is provided in the magnetic pole, there is a possibility that the attracting force may be lowered. The inventor of the present invention has found that even a small groove width that keeps the decrease in the attractive force within an allowable range is effective in preventing needle selection mistakes. That is, since the groove in the running direction is formed, even when the lubricating oil or the like falls on the suction surface of the needle selection actuator, the lubricating oil is used when the armature portion of the knitting needle selector is sucked and relatively slid. Etc. can be scraped out along the groove to prevent needle selection mistakes.

また本発明によれば、溝は制御磁極の表面を通るので、制御磁極に潤滑油が降りてきても、潤滑油は溝に沿って掻き出され、吸着状態の電磁的な制御に、潤滑油の付着が影響しにくくなり、選針ミスを防ぐことができる。   Further, according to the present invention, since the groove passes through the surface of the control magnetic pole, even if the lubricating oil falls on the control magnetic pole, the lubricating oil is scraped out along the groove, and the lubricating oil is used for electromagnetic control of the attracted state. The sticking of the ink is less likely to be affected, and needle selection mistakes can be prevented.

また本発明によれば、吸着面は、溝が形成される磁極と、その磁極に走行方向で隣接し、幅方向に間隔をあけて配列され、間隔に該溝が形成される2つの磁極とを、少なくとも備える。2つの磁極の間隔に溝が形成され、2つの磁極の吸着力の低下を防ぐことができる。   According to the present invention, the attracting surface includes a magnetic pole in which a groove is formed, two magnetic poles adjacent to the magnetic pole in the running direction, arranged in the width direction with an interval therebetween, and the groove is formed in the interval. At least. A groove is formed in the interval between the two magnetic poles, and a decrease in the attractive force of the two magnetic poles can be prevented.

また本発明によれば、制御磁極では吸着のみを行う非制御磁極から漏れる磁束の影響を受けにくくすることができる。   Further, according to the present invention, the control magnetic pole can be made less susceptible to the influence of magnetic flux leaking from the non-control magnetic pole that performs only adsorption.

さらに本発明によれば、前後の針床が歯口を挟んで対向し、前後の各針床は、歯口に接近すると上昇し、歯口から離れると下降するように傾斜して配置される横編機で、選針アクチュエータを下側に配置して、潤滑油が吸着面に溜るようになっても、吸着面に溝を設けるので、選針ミスを防ぐことができる。   Further, according to the present invention, the front and back needle beds are opposed to each other with the tooth opening interposed therebetween, and the front and rear needle beds are inclined so as to rise when approaching the tooth opening and to descend when leaving the tooth opening. Even if the needle selection actuator is arranged on the lower side in the flat knitting machine and the lubricating oil accumulates on the suction surface, a groove is provided on the suction surface, so that a needle selection mistake can be prevented.

図1は、本発明の実施の一形態として3列ヨークタイプの選針アクチュエータ31について、吸着面32の概略的な構成を示す。選針アクチュエータ31で図4および図5に示す選針アクチュエータ24と対応する部分には同一の参照符を付して、重複する説明を省略する。選針アクチュエータ31では、吸着面32に、溝33a,33b,33cが設けられる。溝33a,33b,33cは、針床2に対してキャリッジ3が往復走行する際に、吸着面32に対してセレクタ14の接極部14fが相対的に移動する図の横方向で、吸着面32の両端間に延びるように設けられる。このような溝33a,33b,33cを設ける選針アクチュエータ31を図4の横編機1で選針アクチュエータ24に代えて用いることによって、キャリッジ3の走行時に潤滑油を掻き出すことができ、潤滑油の付着に由来する選針ミスの低減を図ることができる。   FIG. 1 shows a schematic configuration of a suction surface 32 of a three-row yoke type needle selection actuator 31 as one embodiment of the present invention. Parts corresponding to the needle selection actuator 24 shown in FIGS. 4 and 5 in the needle selection actuator 31 are denoted by the same reference numerals, and redundant description is omitted. In the needle selection actuator 31, grooves 33a, 33b, and 33c are provided on the suction surface 32. The grooves 33a, 33b, and 33c are arranged in the horizontal direction of the drawing in which the contact portion 14f of the selector 14 moves relative to the suction surface 32 when the carriage 3 reciprocates with respect to the needle bed 2. 32 is provided so as to extend between both ends. By using the needle selection actuator 31 provided with such grooves 33a, 33b, and 33c in place of the needle selection actuator 24 in the flat knitting machine 1 of FIG. 4, the lubricating oil can be scraped when the carriage 3 travels. It is possible to reduce needle selection mistakes resulting from the adhesion of.

中央の溝33bは、制御吸着部の磁極25a,25bの間隔の非磁性材25cの部分を通る。非制御吸着部では、磁極26bの表面を貫通するように形成される。中央の溝33bに対して両側の溝33a,33cは、非制御吸着部では磁極26a,26b間の非磁性材26dと磁極26b,26c間の非磁性材26eの部分をそれぞれ通るけれども、制御吸着部では、磁極25a,25bの表面をそれぞれ貫通するように形成される。   The central groove 33b passes through the portion of the nonmagnetic material 25c that is spaced between the magnetic poles 25a and 25b of the control attracting portion. The non-controlled attracting part is formed so as to penetrate the surface of the magnetic pole 26b. Although the grooves 33a and 33c on both sides of the central groove 33b pass through the nonmagnetic material 26d between the magnetic poles 26a and 26b and the nonmagnetic material 26e between the magnetic poles 26b and 26c, respectively, The part is formed so as to penetrate the surfaces of the magnetic poles 25a and 25b.

なお、制御吸着部の磁極25a,25bが走行方向に有する長さPは、針床2での編針10の配列ピッチに対応する。たとえば、25.4mm(1インチ)当り12本の編針が配列される12ゲージ(G)では、2mmとなる。磁極25a,25bが走行方向に垂直な幅方向に有する幅Tは、たとえば3.5mmとなる。   In addition, the length P that the magnetic poles 25a and 25b of the control suction portion have in the traveling direction corresponds to the arrangement pitch of the knitting needles 10 on the needle bed 2. For example, for 12 gauge (G) in which 12 knitting needles are arranged per 25.4 mm (1 inch), the distance is 2 mm. The width T that the magnetic poles 25a, 25b have in the width direction perpendicular to the traveling direction is, for example, 3.5 mm.

図2は、図1の切断面線II−IIから見た断面構成を示す。前述のように、中央の溝33bは、磁極26bの表面に設けられているので、磁極26bの吸着力の低下を許容することができる範囲とすることが望ましい。特に磁極25a,25b,26c上に形成される部分で、溝33a,33b,33cの幅は吸着力に影響するけれども、深さは吸着力に影響しない。ただし、深さを深くすると、潤滑油を掻き出す油対策の効果には貢献しなくなる。図では横方向で示される溝幅Wが0.5mm〜1.2mm程度であり、図では縦方向で示される深さDが0.1mm〜0.5mm程度であれば、吸着力の低下は許容範囲内であり、油対策の効果が得られることが判明している。   FIG. 2 shows a cross-sectional configuration viewed from the section line II-II in FIG. As described above, since the central groove 33b is provided on the surface of the magnetic pole 26b, it is desirable that the central groove 33b be within a range in which a decrease in the attractive force of the magnetic pole 26b can be allowed. In particular, in the portions formed on the magnetic poles 25a, 25b, and 26c, the widths of the grooves 33a, 33b, and 33c affect the attracting force, but the depth does not affect the attracting force. However, if the depth is increased, it will not contribute to the effect of oil countermeasures that scrape out the lubricating oil. In the figure, if the groove width W shown in the horizontal direction is about 0.5 mm to 1.2 mm, and the depth D shown in the vertical direction in the figure is about 0.1 mm to 0.5 mm, the decrease in the adsorption force is It is within the allowable range, and it has been found that the effect of oil countermeasures can be obtained.

なお、溝33a,33b,33cの断面形状は円弧状である。このような断面形状は、非磁性材26d,26eとして液状の合成樹脂で磁性材間を充填する際に、円形断面の線材を表面に保持し、合成樹脂の固化後に線材を除去して、吸着面32の全体を研磨することで得ることができる。溝33a,33b,33cの断面形状は、矩形など、円弧状とは異なる形状でもよく、また、吸着面32を平坦に研磨した後で、溝33a,33b,33cを切削加工して形成することもできる。   In addition, the cross-sectional shape of the grooves 33a, 33b, and 33c is an arc shape. Such a cross-sectional shape is such that when the space between the magnetic materials is filled with the liquid synthetic resin as the nonmagnetic materials 26d and 26e, the wire having a circular cross section is held on the surface, and the wire is removed after the synthetic resin is solidified. It can be obtained by polishing the entire surface 32. The cross-sectional shape of the grooves 33a, 33b, and 33c may be a shape such as a rectangle that is different from the arc shape, and the grooves 33a, 33b, and 33c are formed by cutting after the suction surface 32 is polished flat. You can also.

非磁性材26d,26eの表面下のケース30内には、制御吸着部に磁束を供給する永久磁石34、コイル27a,27bおよび磁心35a,35bと、非制御吸着部に磁束を供給する永久磁石36a,36bおよびヨーク37a,37b,37cなどが収容されている。3列に配置されるヨーク37a,37b,37cの吸着面32での端面は、それぞれ非制御吸着部の磁極26a,26b,26cとなる。各構成部分は、非磁性材26d,26eとなる合成樹脂の充填で固着される。   In the case 30 below the surface of the nonmagnetic material 26d, 26e, a permanent magnet 34, coils 27a, 27b and magnetic cores 35a, 35b for supplying magnetic flux to the control attracting portion, and a permanent magnet for supplying magnetic flux to the non-control attracting portion. 36a, 36b, yokes 37a, 37b, 37c and the like are accommodated. The end surfaces of the suction surfaces 32 of the yokes 37a, 37b, and 37c arranged in three rows are the magnetic poles 26a, 26b, and 26c of the non-controlled suction portions, respectively. Each component is fixed by filling with a synthetic resin to be the nonmagnetic material 26d, 26e.

図3は、本発明の実施の他の形態として2列ヨークタイプの選針アクチュエータ41の概略的な構成を示す。選針アクチュエータ41で、図1に示す選針アクチュエータ31または図5に示す選針アクチュエータ24と対応する部分には同一の参照符を付し、重複する説明を省略する。選針アクチュエータ41の吸着面42は、3本の溝43a,43b,43cを有するけれども、非制御吸着部の磁極46a,46bは特許文献4の吸着面と同様に、2列のヨークの端面として形成される。3本の溝43a,43b,43cを、図1の溝33a,33b,33cとそれぞれ対応する位置に設ける。両側の溝43a,43cは磁極25a,46a;25b,46bの表面を貫通するように形成されるけれども、中央の溝43bは非磁性材25c,46cの領域を貫通して磁極は貫通しないように形成される。   FIG. 3 shows a schematic configuration of a double row yoke type needle selection actuator 41 as another embodiment of the present invention. In the needle selection actuator 41, portions corresponding to the needle selection actuator 31 shown in FIG. 1 or the needle selection actuator 24 shown in FIG.

Three grooves 43a, 43b, and 43c are provided at positions corresponding to the grooves 33a, 33b, and 33c in FIG. The grooves 43a and 43c on both sides are formed so as to penetrate the surfaces of the magnetic poles 25a and 46a; It is formed.

図1や図3では、合計3本の溝33a,33b,33c;43a,43b,43cを設けているけれども、環境に応じて、選針ミスが起こり難いように、溝幅や本数を調整することが望ましい。図1では溝33a,33cが磁極25a,25bをそれぞれ通り、図3では溝43a、43cが磁極46a,46bをそれぞれ通るけれども、少なくとも一つの溝が磁極を通ればよい。また、図1や図3に示すように、横方向に水平な溝33a,33b,33c;43a,43b,43cではなく、傾斜させた溝を設けるようにしてもよい。潤滑油の流量が多いような場合、傾斜させれば、潤滑油の流下を促進させ、吸着面32,42への付着量を低減することができる。   1 and 3, a total of three grooves 33a, 33b, and 33c; 43a, 43b, and 43c are provided. However, the groove width and the number of the grooves are adjusted so that a needle selection error hardly occurs according to the environment. It is desirable. In FIG. 1, the grooves 33a and 33c pass through the magnetic poles 25a and 25b, respectively. In FIG. 3, the grooves 43a and 43c pass through the magnetic poles 46a and 46b, respectively, but at least one groove may pass through the magnetic poles. Moreover, as shown in FIG. 1 and FIG. 3, you may make it provide the groove | channel inclined rather than the horizontal groove | channel 33a, 33b, 33c; 43a, 43b, 43c horizontally. When the flow rate of the lubricating oil is large, if it is inclined, the flow of the lubricating oil can be promoted and the amount of adhesion to the adsorption surfaces 32 and 42 can be reduced.
