Description
本発明は、前後２列のニードル列を有するダブルラッシェル機における筬振り装置、特に前後部のニードル列が各１回づつ交互に上下動する１編成サイクル中に導糸筬が３回の筬振り運動を行うにした筬振り装置に関するものである。 The present invention relates to a swing device in a double raschel machine having two front and rear needle rows, and in particular, the yarn guide rod is swung three times during one knitting cycle in which the front and rear needle rows move up and down alternately once each time. The present invention relates to a swinging device that performs exercise.
前後２列のニードル列を有するダブルラッシェル機は、通常、表裏の基布を連結糸で連結してなる比較的厚みの大きい２面式経編地を編成することが多い。この場合、前部ニードル列での基布編成のための前部地糸用筬、後部ニードル列での基布編成のための後部地糸用筬、および前後両基布を連結するための連結糸を導糸するための連結糸用筬等の複数の導糸筬が用いられる。これらの導糸筬は、ニードル列による編成部の上方に支持された揺動可能な筬振りハンガーに取着されており、前後部のニードル列の編成のための上下動に対応して、各ニードル列がそれぞれ上昇位置にある間に糸の掛け渡し動作を行うように編機前後方向に揺動する運動（筬振り運動）を行う。 In general, a double raschel machine having two front and rear needle rows often knits a relatively thick two-side warp knitted fabric formed by connecting base fabrics on the front and back sides with connecting yarns. In this case, the front ground yarn ridge for knitting the base fabric in the front needle row, the rear ground yarn heel for the base fabric knitting in the rear needle row, and the connection for connecting both the front and rear base fabrics A plurality of yarn guide rods such as a connecting yarn rod for guiding the yarn is used. These yarn guides are attached to a swingable swinging hanger supported above the knitting portion by the needle row, and corresponding to the vertical movement for knitting the needle row at the front and rear portions, While the needle rows are in their raised positions, a motion (swinging motion) that swings in the longitudinal direction of the knitting machine is performed so as to perform a yarn passing operation.
すなわち、ダブルラッシェル機の編成サイクルでは、前後部のニードル列を上下動させるカム機構を備える駆動軸（カム軸）が１回転する間に、前後部のニードル列の双方が下降位置にある状態を介して、前後部一方のニードル列と他方のニードル列とがそれぞれ交互に１回づつ上下動する。そのため、前記の導糸筬の揺動すなわち筬振り運動は、前後部ニードル列の１編成サイクル中の前記上下動に対応して、前部ニードル列と後部ニードル列とに対してそれぞれ糸の掛け渡し動作するために、筬振りハンガーと共に数回往復揺動する筬振り運動を行う。 That is, in the knitting cycle of the double raschel machine, both the front and rear needle rows are in the lowered position while the drive shaft (cam shaft) having a cam mechanism for moving the front and rear needle rows up and down is rotated once. Accordingly, one needle row and the other needle row in the front and rear portions are alternately moved up and down once each. Therefore, the swinging movement, that is, the swinging movement of the yarn introduction rod, is applied to the front needle row and the rear needle row, respectively, in response to the vertical movement during one knitting cycle of the front and rear needle rows. In order to perform the handing operation, a swing motion is performed that swings back and forth several times with the swing hanger.
この際、前記導糸筬により前部のニードル列と後部のニードル列とに交互に糸の掛け渡し動作をすることから、常に一定の振り位置で筬振りするのでは、前後２列のニードル列の間隔が大きくなるほど振り幅も大きくなり、編成運転の速度アップや騒音抑制等の点で不利である。そのため、前部ニードル列に対する糸掛け渡し動作のため導糸筬の筬振り位置と、後部ニードル列に対する掛け渡し動作のための筬振り位置とを、前後部それぞれのニードル列の側に位置をずらせて、振り幅を小さくするように設定している。 At this time, since the yarn is alternately transferred to the front needle row and the rear needle row by the yarn introduction rod, if the yarn is always swung at a fixed swing position, the front and rear needle rows are two rows. The larger the interval, the larger the swing width, which is disadvantageous in terms of speeding up the knitting operation and suppressing noise. Therefore, the swing position of the yarn introduction rod for the yarn passing operation with respect to the front needle row and the swing position for the transfer operation with respect to the rear needle row are shifted to the respective needle row sides in the front and rear portions. The swing width is set to be small.
実際上は、前後部のニードル列が交互に上昇するとともに、その間に両ニードル列が降下した状態になることから、前部ニードル列に対し掛け渡し動作するための筬振り位置と、後部ニードル列に対して掛け渡し動作するための筬振り位置との間で、中間位置で１回往復揺動するようにして、１編成サイクル中に３回の筬振り運動する方法が採用されることが多い。 In practice, the needle rows at the front and rear are alternately raised, and both needle rows are lowered between them, so that the swinging position for the transfer operation to the front needle row and the rear needle row In many cases, a method of swinging three times during one knitting cycle is employed so that the swinging position is reciprocated once at an intermediate position between the swinging position for performing the transfer operation with respect to the vehicle. .
図１０は、前後部のニードル列１０１ａ，１０１ｂが各１回づつ交互に上下動する１編成サイクル中に３回筬振りする従来の筬振り装置の１例を示しており、次のように構成されている。 FIG. 10 shows an example of a conventional swinging device that swings three times during one knitting cycle in which the front and rear needle rows 101a and 101b move up and down alternately one by one. The configuration is as follows. Has been.
編機の下部、すなわち前後部のニードル列１０１ａ，１０１ｂによる編成部より下方の編機下部に備えるカムボックス１１０内に、前部ニードル列１０１ａと後部ニードル列１０１ｂを上下動させるカム機構（図示省略）を有する駆動シャフト（カム軸）１１４と、これとは別に前記筬振りハンガー１０６を揺動させる駆動シャフト１１２とを備えている。一方、前記編成部の上方には、前記導糸筬１０５を支持する筬振りハンガー１０６が揺動可能に支持されている。前記筬振りハンガー１０６を支持する支持軸部１０７には揺動駆動レバー１５０が連結されており、前記一方の駆動シャフト１１２に有するエキセン機構１１１に連結された連結ロッド等の伝動連結部材１２２ａが前記揺動駆動レバー１５０に連結されている。また、他方の駆動シャフト１１４に有するエキセン機構１２４に連結された連結ロッド等の伝動連結部材１２２ｂが、前記筬振りハンガー１０６の一端部に連結されている。そして、前記一方の駆動シャフト１１２と他方の駆動シャフト１１４の回転比が３：１とされ、前記駆動シャフト１１４の１回転による１編成サイクル中に、前記一方の駆動シャフト１１２が３回転することで、エキセン機構１１１による３回の変位運動が揺動駆動レバー１５０に伝達されて、前記筬振りハンガー１０６つまりは導糸筬１０５が３回往復揺動するとともにとともに、この揺動変位に、前記他方の駆動シャフト１１４の１回転によるエキセン機構１２４の変位運動に伴う揺動変位が合成されることにより、前後部のニードル列１０１ａ，１０１ｂの上下動に対応して、該ニードル列１０１ａ，１０１ｂに対する糸の掛け渡し動作のための筬振り位置を変更するように設定されている。 A cam mechanism (not shown) that moves the front needle row 101a and the rear needle row 101b up and down in a cam box 110 provided in the lower part of the knitting machine, that is, in the lower part of the knitting machine below the knitting part of the front and rear needle rows 101a and 101b. ) And a drive shaft 112 that swings the swing hanger 106 separately from the drive shaft (cam shaft) 114. On the other hand, above the knitting portion, a swing hanger 106 that supports the yarn introduction rod 105 is swingably supported. A swing drive lever 150 is connected to the support shaft portion 107 that supports the swing hanger 106, and a transmission connecting member 122 a such as a connecting rod connected to the eccentric mechanism 111 included in the one drive shaft 112. The swing drive lever 150 is connected. A transmission connecting member 122 b such as a connecting rod connected to the eccentric mechanism 124 on the other drive shaft 114 is connected to one end of the swing hanger 106. The rotation ratio between the one drive shaft 112 and the other drive shaft 114 is 3: 1, and the one drive shaft 112 rotates three times during one knitting cycle of one rotation of the drive shaft 114. Then, the three displacement movements by the eccentric mechanism 111 are transmitted to the swing drive lever 150, and the swing hanger 106, that is, the yarn introduction thread 105 swings back and forth three times. By synthesizing the rocking displacement associated with the displacement movement of the eccentric mechanism 124 by one rotation of the drive shaft 114, the yarn with respect to the needle rows 101a and 101b corresponding to the vertical movement of the front and rear needle rows 101a and 101b. It is set to change the swing position for the transfer operation.
しかしながら、前記従来の装置の場合、筬振りハンガー１０６を揺動させ筬振り運動させるためのロッドやレバー等の伝動連結部材１２２ａ，１２２ｂが、編機の前後それぞれに配置されることになり、しかも筬振りハンガー１０６の支持軸部１０７に連結される揺動駆動レバー１５０も必要であり、筬振り運動のための装置の部品点数が多く、部品管理が面倒で、製作上の組み立て工数が増し、コスト高になる上、編機前後部の双方に備える前記伝動連結部材が保守あるいは運転開始当初の糸通し作業等の邪魔になる虞もある。 However, in the case of the conventional apparatus, transmission connecting members 122a and 122b such as rods and levers for swinging and swinging the swing hanger 106 are disposed on the front and rear sides of the knitting machine, respectively. The swing drive lever 150 connected to the support shaft portion 107 of the swing hanger 106 is also necessary, the number of parts of the device for the swing motion is large, the parts management is troublesome, and the assembly man-hours in production increase. In addition to the increase in cost, the transmission connecting members provided in both the front and rear portions of the knitting machine may interfere with maintenance or the initial threading operation.
なお、特許文献１には、ダブルラッシェル機の筬振り装置として、前後部のニードル列に対する糸の掛け渡し動作のための筬振り幅を小さくするために、筬振りハンガーを、前後部の地糸用筬を支持する部材と連結糸用筬を支持する部材との２部材で構成し、該両部材の揺動変位を合成することにより、前後部それぞれのニードル列に対して掛け渡し動作する際の前後の筬振り位置において、連結糸筬の振り位置をずらせて、振り幅を小さくすることが示されている。

しかしながら、この場合も、前記筬振りハンガーの２部材を揺動動作させるための伝動連結部材が、編機下部の前後部に配した２本の駆動シャフトに有するカム機構に連結されたロッド等の伝動連結部材が、編機の前後部において上方に延びて配置されて、前記筬振りハンガーの支軸部と筬振りハンガーとに連結されていることには変わりがなく、部品点数が多く成る等、前記同様の問題を有するものである。

A portion for synthesizing the dynamic displacement is provided in the cam box 10.
前記第１の駆動シャフト１２と前記第２の駆動シャフト１４とは、図７のように、例えばタイミングベルト、チェーン等の回転伝達手段１６を介して、回転比３：１で連動回転するように設けられている。前記回転伝達手段１６として歯車を利用することもできる。通常、前記第１の駆動シャフト１２に駆動モータ１７が連結されて回転駆動される。 As shown in FIG. 7, the first drive shaft 12 and the second drive shaft 14 rotate together at a rotation ratio of 3: 1 via a rotation transmission means 16 such as a timing belt or a chain. Is provided. A gear may be used as the rotation transmission means 16. Usually, a drive motor 17 is connected to the first drive shaft 12 and is driven to rotate.
前記の第２の駆動シャフト１４に備えるカム機構１３は、図２のように、該駆動シャフト１４に固設された所定形状のカム部材１８に対し、該駆動シャフト１４と平行な前後の支軸１９ａ，１９ｂに軸支されたカムレバー２０ａ，２０ｂがそれぞれ当接係合して、カム形状に応じて揺動するように設けられている。この前後のカムレバー２０ａ，２０ｂに、それぞれ連結ロッド等の伝動連結部材２１ａ，２１ｂを介して前後部のニードル列１ａ，１ｂの保持部材３ａ，３ｂが連結されており、前記駆動シャフト１４の１回転で、前後部のニードル列１ａ，１ｂが、双方共に下降した状態を介して、それぞれ交互に上下動するように設けられている。すなわち、前記第２の駆動シャフト１４の１回転により、前後部のニードル列１ａ，１ｂが各１回づつ交互に上下動する１編成サイクルをなすように構成されている。 As shown in FIG. 2, the cam mechanism 13 provided in the second drive shaft 14 has a front and rear support shaft parallel to the drive shaft 14 with respect to a cam member 18 having a predetermined shape fixed to the drive shaft 14. Cam levers 20a and 20b pivotally supported by 19a and 19b are provided so as to abut and engage with each other and swing according to the cam shape. The front and rear cam levers 20a and 20b are connected to the holding members 3a and 3b of the front and rear needle rows 1a and 1b via transmission connecting members 21a and 21b such as connecting rods, respectively. Thus, the needle rows 1a and 1b at the front and rear portions are provided so as to move up and down alternately through a state where both are lowered. In other words, one rotation cycle of the second drive shaft 14 constitutes one knitting cycle in which the front and rear needle rows 1a and 1b move up and down alternately once each time.
そして、前記第１のエキセン機構１１により揺動するエキセンレバー１５は、前記カムボックス１０内における前記第１及び第２の駆動シャフト１２，１４の上方部に前後方向に配されて、前後方向の中央部付近に揺動支点１５ａが設定され、さらに編機前後方向の一端側が、前記第１のエキセン機構１１の偏心カム１１ａにより上下方向に進退変位するアーム部材１１ｂにピン連結手段等により回動可能に連結され、前記揺動支点１５ａを中心に揺動するように設けられている。１５ｂは前記の回動可能な連結部を示す。 The eccentric lever 15 that is swung by the first eccentric mechanism 11 is disposed in the front-rear direction above the first and second drive shafts 12, 14 in the cam box 10. A swing fulcrum 15a is set near the center, and one end side in the longitudinal direction of the knitting machine is rotated by a pin coupling means or the like to an arm member 11b that is moved forward and backward by an eccentric cam 11a of the first eccentric mechanism 11 It is connected so as to be swingable around the swinging fulcrum 15a. Reference numeral 15b denotes the rotatable connecting portion.
前記エキセンレバー１５は、前記アーム部材１１ｂとの連結側とは前記揺動支点１５ａを挟んで反対側の端部（出力側の端部）に、図のように編機の前後一方側に配される連結ロッド等の伝動連結部材２２が回動可能に連結され、該伝動連結部材２２を介して前記筬振りハンガー６の一端部と連結されており、該エキセンレバー１５の揺動に伴って前記筬振りハンガー６が揺動し前記導糸筬の筬振り運動が行われるようになっている。１５ｃは前記エキセンレバー１５の出力側端部と前記伝動連結部材２２との連結部を示し、６ａは前記筬振りハンガー６の一端部と伝動連結部材２２とのピン連結手段等による回動可能な連結部を示す。
The eccentric lever 15 is arranged on the opposite end (output end) with respect to the swing fulcrum 15a from the connecting side with the arm member 11b, and on the front and rear sides of the knitting machine as shown in the figure. A transmission connecting member 22 such as a connecting rod is rotatably connected, and is connected to one end portion of the swing hanger 6 via the transmission connecting member 22, and with the swing of the eccentric lever 15. The swing hanger 6 is swung to perform a swinging motion of the yarn introduction rod. Reference numeral 15c denotes a connecting portion between the output side end portion of the eccentric lever 15 and the transmission connecting member 22, and 6a is rotatable by a pin connecting means between the one end portion of the swing hanger 6 and the transmission connecting member 22. A connection part is shown.
図の場合、前記エキセンレバー１５と筬振りハンガー６とを連結する伝動連結部材２２として、編機の前後一方側において、前記エキセンレバー１５に連結された第１の連結ロッド２２ａと、前記筬振りハンガー６に連結された第２の連結ロッド２２ｂとが中間レバー２３を介して連結されており、前記エキセンレバー１５の揺動変位を拡大して前記筬振りハンガー６に伝達できるようになっている。前記第１と第２の両連結ロッド２２ａ，２２ｂの中間レバー２３に対する連結位置を調整することにより、筬振りハンガー６に伝達する変位量を調整できる。 In the case of the figure, as the transmission connecting member 22 for connecting the exhaust lever 15 and the swing hanger 6, the first connecting rod 22a connected to the exhaust lever 15 on one of the front and rear sides of the knitting machine, and the swing swing A second connecting rod 22b connected to the hanger 6 is connected via an intermediate lever 23 so that the swing displacement of the eccentric lever 15 can be enlarged and transmitted to the swing hanger 6. . By adjusting the connecting position of the first and second connecting rods 22a, 22b with respect to the intermediate lever 23, the amount of displacement transmitted to the swing hanger 6 can be adjusted.
前記エキセンレバー１５の前記揺動支点１５ａは、前記第２の駆動シャフト１４に備える第２のエキセン機構２４により変位可能に支持されている。具体的には、前記揺動支点１５ａは、前記エキセン機構２４の偏心カム２４ａにより上下方向に進退変位するアーム部材２４ｂに軸支されている。図の場合、前記エキセン機構２４とは別に、例えば支軸１９ｂに取着された支持レバー２５により揺動可能に支持され、前記第２のエキセン機構２４による揺動支点１５ａの支持位置を制御できるように設けられ、一定の位置で上下方向に変位できるようになっている。
The swing fulcrum 15a of the eccentric lever 15 is supported by a second eccentric mechanism 24 provided in the second drive shaft 14 so as to be displaceable. Specifically, the swing fulcrum 15a is pivotally supported by an arm member 24b that moves forward and backward in the vertical direction by an eccentric cam 24a of the eccentric mechanism 24. In FIG., Separately from the eccentric mechanism 24, for example by a support lever 25 which is attached to the support shaft 19 b is swingably supported, controls the support position of the rocking fulcrum 15a by the second eccentric mechanism 24 It is provided so that it can be displaced in the vertical direction at a certain position.
これにより、前記第１のエキセン機構１１による前記エキセンレバー１５の揺動変位に対して、前記第２のエキセン機構２４による揺動支点１５ａの変位が合成されるように設定されされている。特に、前記第１の駆動シャフト１２が３回転する間に前記第２の駆動シャフト１４が１回転することで、前記第１のエキセン機構１１による前記エキセンレバー１５の３回往復の揺動変位に対し、前記第２のエキセン機構２４による前記揺動支点１５ａの１回往復の変位が合成され、これにより、前記３回往復する揺動変位の振り幅や位置、特に前記連結部１５ｃの振り幅や位置がそれぞれ異なるように設定されている。すなわち、前記エキセンレバー１５に連動して揺動する前記筬振りハンガー６には、前記第２の駆動シャフト１４の１回転による１編成サイクル中に、前記の振り幅や位置を異にして３回往復する揺動変位が付与されるようになっており、これにより、前記筬振りハンガー６に支持された各導糸筬（前後地糸用筬及び連結糸用筬）が、前後部のニードル列１ａ，１ｂの上下動に対応するように振り位置を異にして３回の筬振り運動を行うようになっている。 Thus, the displacement of the swing fulcrum 15 a by the second eccentric mechanism 24 is set to be combined with the swing displacement of the eccentric lever 15 by the first eccentric mechanism 11. In particular, when the second drive shaft 14 rotates once while the first drive shaft 12 rotates three times, the eccentric lever 15 is swung back and forth three times by the first eccentric mechanism 11. On the other hand, the one-time reciprocating displacement of the rocking fulcrum 15a by the second eccentric mechanism 24 is synthesized, and thereby, the swing width and position of the rocking displacement reciprocating three times, particularly the swing width of the connecting portion 15c. And their positions are set differently. In other words, the swing hanger 6 that swings in conjunction with the eccentric lever 15 is rotated three times with different swing widths and positions during one knitting cycle by one rotation of the second drive shaft 14. A reciprocating swinging displacement is applied, whereby each yarn guide rod (front and back ground yarn rod and connecting yarn rod) supported by the swing hanger 6 is connected to the front and rear needle rows. Three swinging motions are performed at different swing positions so as to correspond to the vertical movements of 1a and 1b.
またそのため、前記第１のエキセン機構１１及び前記第２のエキセン機構２４については、前記エキセンレバー１５の揺動変位と前記揺動支点１５ａの変位の合成により、前記筬振りハンガー６の揺動による３回の筬振り運動において、１編成サイクル中に前後部のニードル列１ａ，１ｂが各１回づつ交互に上下動するのに対応して、前部ニードル列１ａに対して糸を掛け渡し動作するための該ニードル列１ａ側寄りの筬振り位置と、後部ニードル列１ｂに対して糸を掛け渡し動作するための該ニードル列１ｂ側寄りの筬振り位置と、その中間位置での筬振り位置となるように、両エキセン機構１１，２４の偏心カム１１ａ，２４ａの偏心の位相や大きさが設定される。 Therefore, the first eccentric mechanism 11 and the second eccentric mechanism 24 are caused by the swing of the swing hanger 6 by combining the swing displacement of the eccentric lever 15 and the displacement of the swing fulcrum 15a. In three swinging movements, the front and rear needle rows 1a and 1b move up and down alternately one time during one knitting cycle, and the yarn is passed over the front needle row 1a. Swinging position near the needle row 1a to perform, swinging position close to the needle row 1b for threading the rear needle row 1b, and swinging position at an intermediate position thereof The phase and magnitude of the eccentricity of the eccentric cams 11a, 24a of the two eccentric mechanisms 11, 24 are set so that
図８は、前記１編成サイクル中での前記エキセンレバー１５の揺動変位の合成状態を示している。図中の破線Ａは、１編成サイクルで３回転する前記第１の駆動シャフト１２に有する前記第１のエキセン機構１１による前記エキセンレバー１５の前記連結部１５ｃの揺動変位状態を示し、点線Ｂは、１編成サイクルで１回転する前記第２の駆動シャフト１４に有する前記第２のエキセン機構２４による揺動支点１５ａの変位状態を示し、実線Ｃは、前記エキセンレバー１５の出力側の連結部１５ｃの揺動変位に前記揺動支点１５ａの変位が合成された状態を示しており、１編成サイクル中に振り位置及び振り幅を異にして３回往復揺動している。この揺動変位が前記エキセンレバー１５から伝動連結部材２２を介して前記筬振りハンガー６に伝達される。 FIG. 8 shows a combined state of swing displacement of the eccentric lever 15 in the one knitting cycle. A broken line A in the figure indicates a swing displacement state of the connecting portion 15c of the eccentric lever 15 by the first eccentric mechanism 11 provided in the first drive shaft 12 that rotates three times in one knitting cycle. Indicates a displacement state of the swing fulcrum 15a by the second eccentric mechanism 24 provided on the second drive shaft 14 that rotates once in one knitting cycle, and a solid line C indicates a connecting portion on the output side of the eccentric lever 15 This shows a state in which the displacement of the swing fulcrum 15a is combined with the swing displacement of 15c, and swings back and forth three times at different swing positions and swing widths during one knitting cycle. This swing displacement is transmitted from the eccentric lever 15 to the swing hanger 6 through the transmission connecting member 22.
図９は、筬振りハンガー６に支持された導糸筬の１編成サイクル中の筬振り状態、すなわち前後２列のニードル列１ａ，１ｂ間のセンターを中心とする筬振り状態を示している。図中の実線Ｄは、前記のように合成された揺動変位が前記エキセンレバー１５から伝達される本発明による筬振り状態を示し、破線Ｅは、揺動支点１５ａの変位を合成しない前記エキセンレバー１５の出力側の連結部１５ｃの揺動変位、すなわちエキセン機構１１のみによる揺動変位が筬振りハンガー６に伝達された場合の筬振り状態を示す。 FIG. 9 shows a swing state during one knitting cycle of the yarn guide supported by the swing hanger 6, that is, a swing state centered on the center between the front and rear needle rows 1a and 1b. A solid line D in the figure indicates a swinging state according to the present invention in which the combined swing displacement is transmitted from the eccentric lever 15, and a broken line E indicates the eccentric that does not combine the displacement of the swing fulcrum 15a. The swinging state when the swinging displacement of the connecting portion 15c on the output side of the lever 15, that is, the swinging displacement only by the eccentric mechanism 11 is transmitted to the swinging hanger 6 is shown.
図９から明らかなように、いずれも１編成サイクル中に導糸筬は３回往復揺動して筬振り運動を行うが、合成されない揺動変位による破線Ｅの筬振り運動は、常に一定位置で一定の振り幅で筬振りがなされるのに対し、本発明のように合成された揺動変位による実線Ｄの筬振り運動は、前記第２の駆動シャフト１４の１回転による１編成サイクル中に、導糸筬は振り位置及び振り幅を異にして３回往復揺動し、前後部のニードル列１ａ，１ｂの上下動に対応して、前部ニードル列１ａ側寄りの筬振り位置と、後部ニードル列１ｂ側寄りの筬振り位置、及びその中間の筬振り位置との３回の筬振り運動を行っている。例えば、図面の最も右寄りの位置Ｐ１で前部ニードル列１ａに対し糸の掛け渡し動作を行い、図面の最も左寄りの位置Ｐ２で後部ニードル列１ｂに対し糸の掛け渡し動作を行う。 As is clear from FIG. 9, in all cases, the yarn guide rod swings and reciprocates three times during one knitting cycle, but the swing motion indicated by the broken line E due to the swing displacement that is not synthesized is always at a fixed position. In contrast, the swinging movement of the solid line D by the swing displacement synthesized as in the present invention is performed during one knitting cycle by one rotation of the second drive shaft 14. In addition, the yarn introduction rod swings back and forth three times at different swing positions and swing widths, corresponding to the vertical movement of the front and rear needle rows 1a and 1b, The swinging motion is performed three times at the swinging position closer to the rear needle row 1b and at the intermediate swinging position. For example, the threading operation is performed on the front needle row 1a at the position P1 located on the rightmost side of the drawing, and the threading operation is performed on the rear needle row 1b on the position P2 located on the leftmost side of the drawing.
このように、１編成サイクル中に３回転する第１の駆動シャフト１２に有する第１のエキセン機構１１によるエキセンレバー１５の連結部１５ｃの揺動変位に、１編成サイクル中に１回転して前後部のニードル列１ａ，１ｂを上下動させる第２の駆動シャフト１４に有する第２のエキセン機構２４による揺動支点１５ａの変位を合成して、導糸筬を支持する筬振りハンガー６に伝えるようにしたことにより、１編成サイクルの前後部のニードル列１ａ，１ｂの上下動に対応して、振り位置を異にしかつ振り幅を小さくした３回の筬振り運動を行うことができ、これにより編成上の速度アップや騒音防止に寄与できる。 As described above, the swing displacement of the connecting portion 15c of the eccentric lever 15 by the first eccentric mechanism 11 provided in the first drive shaft 12 that rotates three times during one knitting cycle causes one rotation during one knitting cycle to move back and forth. The displacement of the oscillating fulcrum 15a by the second eccentric mechanism 24 of the second drive shaft 14 that moves the needle rows 1a and 1b up and down is synthesized and transmitted to the swing hanger 6 that supports the yarn introduction rod. As a result, three swing motions with different swing positions and smaller swing widths can be performed in response to the vertical movement of the needle rows 1a and 1b at the front and rear portions of one knitting cycle. It can contribute to speedup and noise prevention.
また、前記の揺動変位の合成を編機下部で行うことにより、１編成サイクル中に３回筬振り運動するものでありながら、揺動変位を筬振りハンガーに伝える伝動連結部材等の構成を簡略化できて、従来よりも部品点数が少なくて済み、製造上の部品管理が容易で、組み立て工数を低減でき、コスト低下に寄与できる。 In addition, by combining the above-mentioned swing displacement at the lower part of the knitting machine, a structure of a transmission connecting member that transmits the swing displacement to the swing hanger while swinging three times during one knitting cycle is provided. It can be simplified, and the number of parts can be reduced as compared with the conventional one. Manufacturing parts management is easy, the number of assembly steps can be reduced, and the cost can be reduced.
さらに、揺動変位を筬振りハンガーに伝える伝動連結部材を、図のように編機前後の一方に設けるだけでよいので、ニードルの交換等の保守作業あるいは運転開始当初の糸通し作業等を前記伝動連結部材を有さない側から容易に行えることにもなる。 Further, since a transmission connecting member for transmitting the swing displacement to the swing hanger only needs to be provided on one of the front and rear sides of the knitting machine as shown in the figure, maintenance work such as needle replacement or threading work at the beginning of operation is performed as described above. It can also be easily performed from the side having no transmission connecting member.
