201245528 六、發明說明: L名务明戶斤屬才支4軒今貝 發明領域 本發明係有關於一種能形成完整線跡的縫紉機。 t先前技術3 發明背景 例如,當以一縫紉機根據送布前進方向與一縫針與一 梭子間的相對位置關係之間的關係來形成鎖型針步 (lockstitches)時’以如第37A圖所示將一上線與一下線以良 好平衡的方式交織而形成完整線跡(perfect itches),或如 第37B圖所示在僅將一上線螺旋纏捲的狀態可形成加繞線 跡(hitch stitches)。 完整線跡於上線的張力與下線的張力之間具有優良的 平衡,且視覺上美觀加工而具有相互匹配的表面側與背面 側,且改善工件的縫紉品質。另一方面,對於加繞線跡, 易使上線的張力變弱,且缺乏與下線張力之平衡,使其接 縫不均勻,且使表面側與背面側彼此不同而產生不佳的外 觀,因此加繞線跡會破壞工件的縫紉品質。 因此’於習用縫紉機中’例如jP09_22〇391A所揭露, 安裝有一使用遲滯剎車之旋轉式緊線器,且藉由控制一剎 車扭力來增加§玄等線的緊度,以防止於加繞線跡情況造成 之線緊度不足’且可形成一緊固接縫。201245528 VI. INSTRUCTIONS INSTRUCTIONS: The invention relates to a sewing machine capable of forming a complete stitch. BACKGROUND OF THE INVENTION For example, when a lock stitch is formed by a sewing machine in accordance with a relationship between a feed advance direction and a relative positional relationship between a needle and a shuttle, 'as shown in FIG. 37A An upper line and a lower line are interwoven in a well-balanced manner to form a perfect itches, or a state in which only one upper thread is spirally wound as shown in Fig. 37B can form a stitch stitches. The complete stitch has an excellent balance between the tension of the upper thread and the tension of the lower thread, and is visually beautifully processed to have mutually matching surface side and back side, and improves the sewing quality of the workpiece. On the other hand, for the winding stitches, the tension of the upper thread is weakened, and the balance with the tension of the lower thread is lacking, the seam is uneven, and the surface side and the back side are different from each other, resulting in a poor appearance. Adding a stitch will destroy the sewing quality of the workpiece. Therefore, as disclosed in the conventional sewing machine, for example, jP09_22〇391A, a rotary tensioner using a hysteresis brake is installed, and the tightness of the 等Xuan line is increased by controlling a brake torque to prevent the winding stitch from being twisted. The condition caused by insufficient line tightness' and a fastening seam can be formed.
於能藉由依據縫紉資料將一布於一水平面上移動至一 位置而形成一縫紉圖案之縫紉機中,例如jp2〇〇8_〇23261A 201245528 所揭露,可藉由控制該下線路徑使得用以各線跡之形成可 根據一送布方向將該下線路徑相對於一孔於左側與右側之 間轉換,來避免產生加繞線跡。 然而’在JP09-220391A中所述的習用縫紉機僅能避免 因加繞線跡所致的線緊度之不足,且儘管該縫紉機能改善 縫紉的視覺呈現仍無法制止加繞線跡本身。除此之外,端 視該工件及線,其適合的線拉力不同,因此一適當線拉力 要根據縫紉狀況變化來決定與調整。 加繞線跡不僅是由線跡點(stitch point)相對於下線路 徑的相對位置關係所造成,亦會因縫線時自縫針移動向_ 布之上線是否纏繞於該縫針的右側或左側上所造成。然 而’在JP2008-023261A所揭露之習用縫紉機無法解決隨上 線與縫針的纏繞方向所產生的加繞線跡。 於JP2008-023261A中所述的縫紉機中,下線路徑是藉 拉線工作來導正至左或右,以使下線的張力可值呈高度狀 態。因此,上線會被拉引且上線與下線的結點會呈下垂狀 態’線緊度會減弱,且縫紉產品的品質會降低。 進一步地’當位移下線路徑時,縫紉機的轉逮需降低, 如此會降低縫紉效率。 C發明内容3 發明概要 本發明的目的在於更有效率地防止加繞線跡。本發明 的另一目的在於縫紉期間時防止線緊度減弱同時避免加繞 線跡。本發明的再一目的是在於實現高速縫紉同時避免加 201245528 繞線跡。 根據本發明的一型態,— g ^ m '、機包括一固持一縫針 二置:上下移動之針样;—組構成轉動以將—上線與一 4之梭子;—作為1動源用以驅動該針捍上下移 ,且該梭子轉動之縫匆機馬達;一組構成使該針桿繞該針 才干的上下移動的軸轉動之針桿轉動機構;一組構成藉一拉 =構件於—針板底下拉住該下線之拉線機構;一組構成沿 水平:移動一工件之布移動機構;及一控制器,其組構 :依據定義-線跡點或每線跡該工件的移動量之縫初資料 控制。亥布移動機構以形成—縫幼圖案,及隨意選擇地控 2針才干轉動機構及該拉線機構。該控制器包含用以決定 =移動機構移動該工件的移動方向之決定農置,及控制 4控制裝置疋用以根據以該決定裝置所決定之移動 針㈣該拉線機構的抵線工作之執行或停留或以該 定構對該針桿的轉動工作,或是用以根據以該決 二向’選擇地執行以該拉線機構之拉 線工作或以該針桿轉動機構之針桿轉動工作。 包八=本發明的另—型態,該控制η組構為執行以下 決定該布移動機構移動該工件之移動方向, 根據錢定之移動方向控心該拉線機制拉線工作之 _或<了留或以该針桿轉動機構對該針桿的轉動工作。 該控制器可包含— 存早元,其儲細雜線機構的 示命〜ί 轉動機構騎㈣動卫作之執行的指 7、中繞該縫針與該針桿的上下移動關連之上下移 201245528 動路徑的送布方向之整個角度範圍被分成數區段,且該指 7對每一該等區段作儲存,並且根據由該決定裝置所決定 的移動方向,該控制器可讀取對應於含蓋有該移動方向的 區段之指令,且依據所讀取指令作動該拉線機構或該針桿 轉動機構·》 Ψ 該等區段可由根據加繞線跡的發生可能性及加繞線跡 的因素將角度範圍分類所界定而成。 該控制裝置可包含識別裝置,用以識別含蓋由該決定 裝置所決定的移動方向之區段,且根據由該識別裝置所識 別之區段,該控制裝置控制該拉線機構或以該針桿轉動機 構之作動(例如,以該拉線機構的拉線工作之執行或停留或 以該針桿轉動機構對該針桿的轉動工作)。 例如,該控制器可執行識別含蓋該決定的移動方向之 區段的步驟,且根據該識別的區段控制以該拉線機構的拉 線工作之執行或停留或以該針桿轉動機構對該針桿的轉動 工作。 該拉線機構可包含:一拉線馬達、一以該拉線馬達致 動之拉線凸輪構件、-受到該拉線凸輪構件所施加的運動 之拉線從動件’及一拉線連桿機構’其組構為將該拉線從 動件的一下線拉住作動力傳送至該拉線構件,其中該拉線 凸輪構件包含—凸輪部’其包括—不會對該拉線構件施加 拉線作動之非作動段,及一對該拉線構件施加拉線作動之 作動段,該非作動段及該作動段是連續形成,且其中該控 制器控制該拉線馬達,以致於該拉線馬達當該拉線從動件 201245528 與該拉線凸輪構件的非作動段銜接的同時加速。 該拉線凸輪構件的非作動段可形成於該作動段的各側 上,以使該作動段是介於該非作動段中。 該拉線機構可包含一拉線馬達及一拉線連桿機構,其 組構為將該拉線馬達的運動傳送至該拉線構件,以使該拉 線構件的一遠端部以一繞轉方式移動,其中該拉線構件是 設置為使該拉線構件的遠端部接觸該下線且當該拉線構件 的遠端部為該繞轉運動的軌跡之一作動段時拉住該下線。 當執行拉線工作時,該控制器可控制該拉線馬達,以 使該拉線馬達當該拉線構件的遠端部是在該繞轉運動的軌 跡的作動段外側時開始驅動,且使得該拉線馬達在該拉線 構件的遠端部到達該作動段之前加速。 該拉線機構可包含一以該縫紉機馬達致動之拉線凸輪 構件、一受到該拉線凸輪構件所施加的運動之拉線從動 件,及一連桿機構,其包含數拉線連桿體,組構以將自該 拉線從動件之下線拉住作動力傳送至該拉線構件,其中該 拉線連桿機構是組構為,藉將該數拉線連桿體其中一者與 另一構件可轉動連結處之一轉動連結部位移至與該等拉線 連桿體另一者的一轉動連結部同心之位置,使自該拉線從 動件的力無法傳動至該拉線構件,且其中該控制器藉控制 一致動器執行該拉線工作,該致動器將該等拉線連桿體的 該其中一者之轉動連結部位移至與該等拉線連桿體的該另 一者之轉動連結部同心之位置。 該針桿轉動機構可包含一針桿轉動馬達、一以該針桿 201245528 轉動馬達致動之針桿轉動凸輪一/ 輪構件所施加的運動之針 、一文到該針桿轉動凸 逆纫之針知轉動從動件, 轉動從動件的轉動作動傳送至該針桿之傳=針桿 針桿轉動凸輪構件包含—凸輪 、’其中該 施加轉動作動之非作動段,:―4括不會對該針桿 作動严, 對該針桿施加轉動作動之 作動I该非作動段及該作動段 乍動之 控制該針桿轉動馬達,以致 W 7 ^控制器 動從動件無針桿轉動凸^ =轉料達^針桿轉 速。 ㈣凸輪構件的非作動段銜接的同時加 :針桿轉動凸輪構件的非作動段 各側上,贿該作缝是介於轉作祕巾。㈣ - = = 機馬達,針桿 之对桿轉動從動件丄=:凸輪構件所施加的運動 體,其_㈣^ 柄_,包含數針桿連桿 节斜炉 、"針桿轉動從動件之轉動作動力傳送至 其中^該轉連桿機構是組構為,藉將該數針桿連桿體 斑 、冓件可轉動連結處之-轉動連結部位移至 自心t杯連才干體另—者的一轉動連結部同心之位置,使 料枯法Γ干轉動攸動件的力無法傳動至該針桿,且該控制器 致動器執行該針桿的轉動工作,該致動器將該等 遠體的„玄其中—者之轉動連結部位移至與該等針桿 連才干體的該另-者之轉動連結部同心之位置。In a sewing machine capable of forming a sewing pattern by moving a cloth on a horizontal surface to a position according to the sewing material, as disclosed in, for example, jp2〇〇8_〇23261A 201245528, the line can be used for controlling the line. The formation of the trace can be switched between the left and right sides with respect to a hole according to a feed direction to avoid the occurrence of the stitching. However, the conventional sewing machine described in JP 09-220391 A can only avoid the shortage of the thread tightness due to the twisting of the stitches, and although the sewing machine can improve the visual appearance of the sewing, the stitching itself cannot be stopped. In addition, depending on the workpiece and the line, the appropriate line tension is different, so an appropriate line pull force is determined and adjusted according to the sewing condition change. The winding stitch is not only caused by the relative positional relationship of the stitch point with respect to the lower thread path, but also because the thread is moved from the needle to the right or left side of the needle due to the movement of the needle. Caused. However, the conventional sewing machine disclosed in JP 2008-023261 A cannot solve the winding stitches generated by the winding direction of the upper thread and the needle. In the sewing machine described in JP 2008-023261 A, the lower thread path is operated by the pull wire to be guided to the left or right so that the tension of the lower thread can be valued to a high state. Therefore, the upper thread will be pulled and the nodes of the upper and lower threads will be drooped. The line tightness will be weakened and the quality of the sewn product will be degraded. Further, when the lower thread path is displaced, the sewing machine needs to be lowered, which reduces the sewing efficiency.

桿24的針桿12側上的端部之導件25,以使該端部可沿上下 方向往復運動。 15 201245528 該上桿22是直接連接於該縫紉機馬達21的輸出軸且受 驅動而旋轉’且該上桿22的旋轉藉由該針桿曲柄23與該曲 柄桿24轉換成上下往復移動並傳送至該針桿12。 一沿該Y軸方向之枢軸26是設置以貫穿該曲柄桿24的 針桿12側上的端部,且該樞軸26可旋轉地軸向支撐二方形 件27及28而以兩端部夾置該曲柄桿24。 設置於該曲柄桿24的針桿12側上的表面上之該方形件 27是經由以下敘述的針桿固持件331及332與該針桿12銜 接,且將該上下移動傳送至該針桿12。設置於與該曲柄桿 24的針桿12相對側上的表面上之該方形件28配合於沿該z 軸方向形成於該臂部111a壁面上之一槽形導件25。具體而 έ,該方形件28是可滑動地配合於該槽形導件25,使得其 使該曲柄桿24的針桿12側上的端部可僅沿該ζ軸方向往復 運動同時制止該端部以X軸方向移動。 據此,該針桿12會受到與該縫紉機馬達21的旋轉同步 之上下方向的往復運動。 梭子 於本貫把例中,將以採用一半旋梭作為該梭子13為例 說明。该半旋梭包含一在一大梭内與該針桿12的上下移動 同步往復轉動之内梭、一容置於該内梭内之梭殼、一容置 於該梭殼内側且供一線捲繞之繞線筒、—施加往復轉動力 至忒内梭之驅動器、一其一端部連結於形成於該上桿22上 的曲柄部之曲柄桿、一具有一臂部連結於該曲柄桿另一 端。卩之往復轉動桿,及一藉由該往復轉動桿增加速度且往 16 201245528 復轉動之下桿。該下桿固持該驅動器且經由該驅動器往復 轉動該内梭。該縫幼機馬達21成為該針桿12上下移動與該 梭子13轉動之驅動源,且一上線是藉由該縫針丨丨的上下移 動與該梭子13的轉動而與一下線交織。該半旋梭的結構與 構形為習知,因此省略其詳細說明。 針桿轉動機構 如第3至5圖所示,該針桿轉動機構3〇包含一針桿基底 31,其可繞該Z軸(繞該針桿12上下移動的中心軸)轉動地支 標於該臂部101a的前端部上,且可上下移動地支撐該針桿 12,以及一操作系統,其經由該針桿基底31施予相對於該 針桿12繞該Z軸之轉動力。 該針桿基底31是形成具有一圓柱形狀,以使其上端部 311及該下端部312彼此成同心,且該等端部藉一矩形架體 部313 —體連結。在該下端部312及該架體部313内,分別固 持有圓柱金屬軸承321及322 ’且一圓桿形針桿12插置於該 二金屬軸承321,322内側。據此’該針桿12是以可沿該2軸 方向上下移動的狀態得到支樓。 在该針桿基底31的上端部311與下端部312外環周上, 分別設置有軸承323,324’且該等軸承3U,324的外環周固持 於該臂部lGla的壁面上。據此,該針桿基細及受該針桿 基底31支撐的該針桿12是可相對於該臂部1〇u繞該z軸轉 動。 該等墊片325,326可維持該等軸承323,324的外環與該 針桿基底31側之間的可滑動性。 17 201245528 一臂構件327螺固於該針桿基底31的上端部311且在該 軸承323底下,使一轉動扭矩可自該操作系統輸入於其内。 該臂構件327形成有一臂部,其以一繞該針桿12的徑向方向 向外延伸,且此臂部的一遠端部是藉一帶肩螺絲連結於構 成該操作系統之其中一連桿體,且經由此臂部可輸入轉動 力0 s亥針桿基底31的架體部313具有沿該Z軸方向之矩形平 面部,且一檢測體328固定於該平面部的上部。該檢測體328 的接近狀態是被一針桿角度感測器329所檢測,該針桿角度 感測器329是一設置於該臂部1〇la壁面上之距離感測器。具 體地,該針桿角度感測器329輸出一對應於與該檢測體328 的距離之檢測訊號’且據此可識別該檢測體328相對於該針 才干角度感測器329的接近狀態或分離狀態。例如,當該檢測 體328在最近處的狀態是界定為該針桿12轉動方向上之一 原始位置時,其可識別出該針桿12是否位於原始位置或是 轉動遠離原始位置》 在該針桿基底31的架體部313之平面部上,螺裝一長導

201245528 動時,該凸部33la亦於該細槽330a内上下移動。該凸部33l这 的水平寬度是设疋為貫質上相等於該細槽33〇a的寬度,據 此,當該針桿基底31繞該Z軸轉動時,該針桿12亦一起轉動。 如第6及7圖所示,一方形件27是可繞該¥轴轉動地受輪 向支撐於該曲柄桿24的下端部之該針桿12側上的表面上。 二垂直配置的針桿固持件331及332是固定於該針桿 12 ’以固持該針桿同時留有—預定間隙。該方形件η是: 由塾片333及334介㈣直置之該針桿固持件33丨與 桿固持件332之間。 土 η〜疋μ具優良摩擦性能之材質製成, 且。玄方形件27的摩擦表面具有優良的可滑動性。分別自兮 等針桿固持件331及332凸㈣料配合於料墊片3^ 334且4等墊片當該針桿^轉動時會與該等針桿固持 331及332—起轉動。 以υιΓ方凸Γ331#設置於該上針桿㈣件331上以自前側 向凸出’且該導板330將該針和繞該冰與該針 :二 <轉動。此時’該等針桿固持件331及332與該 ㈣動’“,被該曲柄桿24找之該方形件^ 桿經由該等塾片333及334定位於該等針 自节务 〃 32之間的狀_,且即使當該針桿轉動時, 12:一機馬達21的上下移動之動力仍可傳送至該針桿 19 201245528 致動之針桿轉動凸輪構件3 5 (以下是以針桿凸輪構件表 不)、一受到自該針桿凸輪構件35的作動之滾輪36(針桿轉動 從動件),及—將該滾輪36的轉動力傳送至該針桿12之傳送 構件。該傳送構件包含一滾輪臂361、一連桿體%〗,及一 臂 327。 該針桿轉動馬達34是受到一附接於該臂部1〇la左側面 之馬達安裝基部341的支撐而成使其輸出軸垂直朝上導向 之狀態,且一驅動鏈輪342設置於此輸出軸上。在該馬達安

不會施加轉動力予該針桿I2之該等非作動段352及353,及 施加轉動力伐針桿u之該作動段ΜΑ是互相連續的。 δ亥針桿轉動機構3〇是在該上桿36〇。的旋轉中一恆定旋 轉角度範圍内’如第24圖所示,在—時點繞該針桿12自身 軸〜於予員定角度範圍往復轉動該針桿12。因此,當縫幼 速度愈向’賴針桿12賴以更高速度往復轉動。 然而,如第12圖所示,一般而言,該馬達具有的速度 特性是’該馬達之加速度在驅動開始瞬間後是小的,一低 速狀態VI會持續—預定時間,之後,該馬達會加速並達到 円速狀恶V2。因此,當以該針桿轉動馬達34將轉動力施 加於違針桿凸輪構件35時,在開始該針桿㈣馬達Μ之驅 動時°亥針桿凸輪構件35是以低速轉動,使得該針桿12的 轉動Τ此跟不上受尚速連續旋轉的縫紉機馬達所驅動之該 針桿12及該梭子13。 因此,該針桿凸輪構件35是設計成使該針桿凸輪構件 35的凸輪部351設有該非作動段352或353,且此非作動段 352或353是設定為該滾輪36的準備位置,且在該針桿轉動 馬達34的驅動開始之後直到到達-高速狀態,該滾輪36會 沿該非作動段352或353相對移動,且當該針桿轉動馬達34 充分加速時,該滾輪36會沿該作動段354相對移動。據此, '•亥針柃12可僅藉利用該針桿轉動馬達料的高速範圍而轉 動,使得該針桿12可以高速轉動。 該控制裝置90控制該針桿轉動馬達34,使得該針桿轉 動馬達34於該針桿凸輪構件35的非作動段352或353開始進 21 201245528 行驅動’a在該針桿轉動馬達34充分加速之後於該作動 段354將轉動力施加於該針桿。 該針桿凸輪構件35具有形成於夹置該作動段354的兩 側上之非作動段352及353,使得當該針桿12往復轉動-次 時,不需往復轉動該針桿凸輪構件35,且可充分的轉動該

以上述構造,於該針桿轉動機構3〇中,在該原始感測 益355檢測到如第9圖所示狀態,即該滾輪36是在該針桿凸 輪構件35的凸輪部35丨上之參考準備位置之後,當該針^轉 動馬達34開始驅動時,該針桿凸輪構件35會經由該驅動鏈 輪342、該正時皮帶344,及該被動鏈輪343開始轉動。 在當s玄針桿轉動馬達34開始驅動時的低速狀態時,該 滾輪36沿該針桿凸輪構件35的非作動段352相對移動,使得 轉動力不會施加於該針桿12及該針桿基底31,且當該針桿 轉動馬達34逐漸加速且達到一高速時,如第1〇圖所示該 滾輪3 6會到達該針桿凸輪構件3 5的作動段3 5 4且相對移 動。據此,該滾輪臂361會轉動以經由該連桿體362轉動該 針桿基底31 ^據此,該針桿12亦會轉動。 該針桿轉動馬達3 4的驅動會持續直到該滾輪3 6脫離該 作動段354且到達該另一非作動段353之一停止位置以為

I: Embodiment 3 Detailed Description of Preferred Embodiment A first embodiment of the present invention will be described with reference to Figs. The sewing machine 100 as the present embodiment described below is a so-called electronic circulation type sewing machine, and includes a holder 81 as a cloth holding portion for holding a cloth to be sewn, and is held in accordance with predetermined sewing materials. The cloth held by the frame 81 is formed by moving the holder 81 relative to a needle to form a slit pattern. Here, the vertical direction in which the needle 11 moves up and down is defined as the Z-axis direction or the up-and-down direction. In addition to this, a horizontal direction is defined as an X-axis direction or a left-right direction, and a horizontal direction orthogonal to the X-axis direction is defined as a Y-axis direction or a front-rear direction. In addition, in the following description, "front" indicates the direction in which the operator performing the sewing operation is located with respect to the sewing machine 100, and "left" indicates the state in which the operator in front of the sewing machine 10 faces the state of the sewing machine 100. The left side and "right" indicate the right side when the operator in front of the sewing machine 100 faces the state of the sewing machine 100. As shown in Fig. 1, the sewing machine 100 includes a needle bar 12 that moves up and down in the Z-axis direction while holding a needle 11 on the lower end portion, and uses a 14 201245528 sewing machine motor 21 as a driving source for the needle. 12 up and down moving needle up and down moving mechanism 20, a needle bar rotating mechanism 30 for rotating the needle bar 12 about a central axis along the Z-axis direction, and a lower line D and an upper line U passing through the hole of the needle 11 The interlaced shuttle 13, a wire pulling mechanism 50 for pulling the lower wire D, a tightening device 70 for changing and adjusting the wire tightness of the upper wire U, a holding cloth and arbitrarily moving along the X-Y plane The cloth moving mechanism 80 is positioned, a control device 90 (controller) for controlling the operation of the individual members, and a sewing machine body 101 supporting the individual members of the sewing machine 100. Sewing frame As shown in Fig. 1, the sewing machine 100 includes the sewing machine main body 101, which is viewed from the X-axis direction as a substantially U-shaped outer shape. The sewing machine main body 101 includes an arm portion 101a that forms an upper portion of the sewing machine 100 and extends in the Y-axis direction, a machine tool portion 101b that forms a lower portion of the sewing machine 100 and extends in the XY-axis direction, and a joint located above and below The arm portion 101a and the vertical drum portion 101c of the machine tool portion 101b. As shown in FIGS. 1 and 2, the needle up-and-down moving mechanism 20 includes a rod 22 disposed inside the arm portion 10a along the Y-axis direction and rotatably supporting the upper rod 22, and a display portion 19, a sewing machine motor 21 coupled to the end of the upper rod 22 and applying a rotational force, a needle bar crank 23 disposed on the distal end side of the arm portion 101a on the other end of the upper rod 22, a crank lever 24 whose center is eccentrically coupled to the center of rotation of the needle bar crank 23, and a guide member 25 for guiding the end portion of the crank bar 24 on the side of the needle bar 12 so that the end portion can be along Reciprocating in the up and down direction. 15 201245528 The upper rod 22 is directly connected to the output shaft of the sewing machine motor 21 and is driven to rotate 'and the rotation of the upper rod 22 is converted into a vertical up and down movement by the needle rod crank 23 and the crank rod 24 and transmitted to The needle bar 12. A pivot 26 in the Y-axis direction is provided to extend through the end of the crank rod 12 on the side of the needle bar 12, and the pivot 26 rotatably axially supports the square members 27 and 28 to be clipped at both ends The crank lever 24 is placed. The square member 27 disposed on the surface on the needle bar 12 side of the crank lever 24 is engaged with the needle bar 12 via the needle bar holders 331 and 332 described below, and the up and down movement is transmitted to the needle bar 12 . The square member 28 provided on the surface on the side opposite to the needle bar 12 of the crank lever 24 is fitted to a groove guide 25 formed on the wall surface of the arm portion 111a in the z-axis direction. Specifically, the square member 28 is slidably fitted to the groove-shaped guide member 25 such that the end portion of the crank rod 24 on the needle bar 12 side can reciprocate only in the z-axis direction while stopping the end portion. The part moves in the X-axis direction. According to this, the needle bar 12 is subjected to the reciprocating motion in the up-and-down direction in synchronization with the rotation of the sewing machine motor 21. In the present example, the shuttle will be described by taking a half of the hook as the shuttle 13. The semi-rotary bobbin includes an inner shuttle that reciprocates in a large shuttle in synchronism with the up-and-down movement of the needle bar 12, a bobbin case accommodated in the inner bobbin, and a bobbin case accommodated inside the bobbin case for a coil a bobbin wound around, a driver that applies a reciprocating rotational force to the inner shuttle, a crank lever whose one end is coupled to a crank portion formed on the upper rod 22, and an arm portion coupled to the other end of the crank rod . The reciprocating rotation lever of the crucible, and a speed increase by the reciprocating rotation lever and the rotation of the lower rod to 16 201245528. The lower rod holds the driver and reciprocates the inner shuttle via the driver. The slit machine motor 21 serves as a drive source for the needle bar 12 to move up and down and the shuttle 13 to rotate, and an upper thread is interlaced with the lower thread by the up and down movement of the needle butt and the rotation of the shuttle 13. The structure and configuration of the hook bobbin are conventional, and thus detailed description thereof will be omitted. The needle bar rotating mechanism is as shown in FIGS. 3 to 5, and the needle bar rotating mechanism 3 includes a needle bar base 31 which is rotatably supported around the Z axis (a central axis about which the needle bar 12 moves up and down) The needle bar 12 is supported on the front end portion of the arm portion 101a and movable up and down, and an operating system that applies a rotational force about the Z axis with respect to the needle bar 12 via the needle bar base 31. The needle bar base 31 is formed to have a cylindrical shape such that the upper end portion 311 and the lower end portion 312 are concentric with each other, and the ends are connected by a rectangular frame portion 313. In the lower end portion 312 and the frame portion 313, cylindrical metal bearings 321 and 322' are respectively fixed and a round rod-shaped needle bar 12 is inserted inside the two metal bearings 321, 322. According to this, the needle bar 12 is a branch in a state in which it can be moved up and down in the two-axis direction. Bearings 323, 324' are respectively provided on the outer circumferences of the upper end portion 311 and the lower end portion 312 of the needle bar base 31, and the outer circumferences of the bearings 3U, 324 are fixed to the wall surface of the arm portion 1G1a. Accordingly, the needle bar base is thin and the needle bar 12 supported by the needle bar base 31 is rotatable relative to the arm portion 1 about the z-axis. The spacers 325, 326 maintain slidability between the outer ring of the bearings 323, 324 and the needle bar base 31 side. 17 201245528 An arm member 327 is screwed to the upper end portion 311 of the needle bar base 31 and under the bearing 323 so that a rotational torque can be input thereto from the operating system. The arm member 327 is formed with an arm portion extending outward in a radial direction around the needle bar 12, and a distal end portion of the arm portion is coupled to one of the links constituting the operating system by a shoulder screw The body portion and the frame portion 313 through which the rotational force of the needle bar base 31 can be input has a rectangular flat portion along the Z-axis direction, and a detecting body 328 is fixed to the upper portion of the flat portion. The proximity state of the detecting body 328 is detected by a needle bar angle sensor 329 which is a distance sensor disposed on the wall surface of the arm portion 1〇1a. Specifically, the needle bar angle sensor 329 outputs a detection signal corresponding to the distance from the detecting body 328 and can thereby identify the proximity state or separation of the detecting body 328 with respect to the needle angle sensor 329. status. For example, when the state of the detecting body 328 is defined as one of the original positions in the rotational direction of the needle bar 12, it can recognize whether the needle bar 12 is in the original position or rotate away from the original position. On the flat portion of the frame portion 313 of the rod base 31, a long guide plate 330 is screwed. A small groove 33〇ae is formed on the guide plate 330 along the z-axis direction on a plane portion of the frame portion 313, and a larger opening than the narrow groove 330a of the guide plate 330 is formed on the guide plate 330. On the back side. A needle bar holder 331 is fixed to the needle bar 12, and a rectangular convex portion 331a extending outward in a radial direction of the needle bar 12 is formed in the needle bar holder 331 as shown in FIGS. 6 and 7. on. The convex portion 33 la is inserted into the narrow groove 3 3 〇a from the back side of the guide plate 330, and when the needle bar 12 moves up and down 201245528, the convex portion 33la is also in the thin groove 330a. Move up and down. The horizontal width of the convex portion 33l is set to be substantially equal to the width of the thin groove 33〇a, whereby the needle bar 12 also rotates together when the needle bar base 31 is rotated about the Z axis. As shown in Figs. 6 and 7, a square member 27 is rotatably supported on the surface of the needle bar 12 side of the lower end portion of the crank bar 24 so as to be rotatable about the spindle. The two vertically disposed needle bar holders 331 and 332 are fixed to the needle bar 12' to hold the needle bar while leaving a predetermined gap. The square piece η is: between the needle bar holder 33 直 and the rod holder 332 which are placed directly by the ridges 333 and 334. Soil η~疋μ is made of a material with excellent friction properties. The friction surface of the cube member 27 has excellent slidability. The needle bar holders 331 and 332 are respectively fitted to the material pad 3^ 334 and the 4th pad is rotated together with the needle bar holders 331 and 332 when the needle bar ^ rotates. The υι Γ Γ 331# is disposed on the upper needle bar (four) member 331 to protrude from the front side ′ and the guide plate 330 wraps the needle and the ice with the needle: <Rotate. At this time, the needle bar holders 331 and 332 and the (four) movements are positioned by the crank bar 24 via the blades 333 and 334. Between the two, and even when the needle bar is rotated, 12: the power of the up and down movement of the motor 21 can be transmitted to the needle bar 19 201245528 Actuated needle bar rotating cam member 3 5 (hereinafter is the needle bar The cam member is not shown, a roller 36 (the needle bar rotating follower) that is actuated from the needle bar cam member 35, and a transmitting member that transmits the rotational force of the roller 36 to the needle bar 12. The member includes a roller arm 361, a link body %, and an arm 327. The needle bar rotation motor 34 is supported by a motor mounting base 341 attached to the left side surface of the arm portion 1〇la. The output shaft is vertically upwardly guided, and a drive sprocket 342 is disposed on the output shaft. On the upper surface of the motor F-based P341, a small-diameter passive sprocket μ is disposed adjacent to the motor shaft. Driving the sprocket 342' and a timing belt 344 is wound around the sprocket wheels 342 and 343' and increasing the rotational force The drive sprocket 342 is transmitted to the driven sprocket 343. The passive key wheel 343 is coupled to the hopper cam member 35' via a -rotor (4) and the rotational force of the passive sprocket 343 is transmitted to the needle bar cam member. 35 to rotate the needle bar cam member 35. In Fig. 11 'the needle bar cam member 35 has a substantial fan shape centered on the hinge, and the -f curved outer edge portion is the cam portion 351 and The action portion 354 between the two-actuated non-actuating segments 352 and 353 and the two non-actuating segment cutters will be associated with the roller wheel shape 'which has two rotational center positions - hate distances. It is bilaterally symmetrical such that the actuating segment is such that the non-four segments 35...53 are continuous and the diameter is gradually reduced from the non-actuating segments 3 52 and 3 53. Specifically, the needle bar member 35 has a cam portion The formation is such that 20 201245528 does not apply a rotational force to the non-actuating segments 352 and 353 of the needle bar I2, and the actuation segment 施加 of the rotational force of the needle bar u is mutually continuous. The mechanism 3〇 is a constant rotation angle in the rotation of the upper rod 36〇. In the circumference, as shown in Fig. 24, the needle bar 12 is reciprocally rotated around the needle shaft 12 at its own axis to a predetermined angular range. Therefore, when the sewing speed is higher, the needle bar 12 is further High-speed reciprocating rotation. However, as shown in Fig. 12, in general, the motor has a speed characteristic that 'the acceleration of the motor is small after the start of the drive, and a low-speed state VI continues—predetermined time, after The motor accelerates and reaches the idle speed V2. Therefore, when the rotation force is applied to the needle bar cam member 35 by the needle bar rotation motor 34, the needle is started when the needle bar (four) motor is started to be driven. The lever cam member 35 is rotated at a low speed so that the rotation of the needle bar 12 cannot keep up with the needle bar 12 and the shuttle 13 driven by the sewing machine motor which is continuously rotated at a constant speed. Therefore, the needle bar cam member 35 is designed such that the cam portion 351 of the needle bar cam member 35 is provided with the non-actuating portion 352 or 353, and the non-actuating portion 352 or 353 is set to a ready position of the roller 36, and After the driving of the needle bar rotation motor 34 is started until the arrival-high speed state, the roller 36 will relatively move along the non-actuating segment 352 or 353, and when the needle bar rotation motor 34 is sufficiently accelerated, the roller 36 will follow the action. Segment 354 moves relatively. Accordingly, the '•海针柃12 can be rotated only by rotating the needle bar to rotate the high speed range of the motor material, so that the needle bar 12 can be rotated at a high speed. The control device 90 controls the needle bar rotation motor 34 such that the needle bar rotation motor 34 starts in the non-actuating segment 352 or 353 of the needle bar cam member 35. 21 201245528 row drive 'a is fully accelerated at the needle bar rotation motor 34 A rotational force is then applied to the needle bar at the actuation section 354. The needle bar cam member 35 has non-actuating sections 352 and 353 formed on both sides of the actuating section 354 so that the needle bar cam member 35 does not need to be reciprocally rotated when the needle bar 12 is reciprocated. The cup cam member 35 can be sufficiently rotated to the side to move the roller relative to the other non-actuating segment 353 from the non-actuating segment. When the next rotation of the needle correction is made, the roller 36 has come into fine contact with the other non-actuating motion, because the running motion can be performed in the non-actuating section 353 until the motor reaches a south speed state. A sensor 355 is provided together with the needle bar cam member 35. The write == 355 can detect the position of the second fixed wheel 36 on the cam portion 351 of the needle bar cam member % by detecting the one fixed to the rotary lever. The self-contained wheel 36 is located at the reference preparation position and can be rotated by the needle bar cam member 35. When the needle bar rotation motor reaches the miscellaneous, the returning wheel 36 can be reached to the operating segment, so that the high-speed turning tool can be performed. 0 ... 疋 is rotatably held on the -f portion 361a of the 361 (bell crank) of the transfer mechanism, and the other of the roller arms 361, &, & is connected by the link body 362 of the '7 hai transmission member The distal end portion is coupled to the arm member 32. The base end side of the two arm portions 361a & 36ib of the member/roller #361 is pivoted to the base of the roller arm of the wall surface of the arm portion by means of the shoulder screw 363 as a pivot. 2012... 22 201245528 The roller arm 361 is energized by a button force coil spring 364 such that the roller 36 can constantly contact the cam portion 351 of the needle bar cam member 35. - a stopper 365 is provided following the roller arm 361 to prevent the 5th needle bar cam member 35 from being excessively passed by a torsion coil spring 364 when the needle bar cam member 35 is excessively rotated and the roller 36 is disengaged from the cam portion 35 Turn. With the above configuration, in the needle bar rotating mechanism 3, the original sensing profit 355 detects a state as shown in Fig. 9, that is, the roller 36 is on the cam portion 35 of the needle bar cam member 35. After the preparation position is referenced, when the needle rotation motor 34 starts driving, the needle bar cam member 35 starts to rotate via the drive sprocket 342, the timing belt 344, and the passive sprocket 343. When the s-needle bar rotation motor 34 starts to drive at a low speed state, the roller 36 relatively moves along the non-actuating section 352 of the needle bar cam member 35, so that a rotational force is not applied to the needle bar 12 and the needle bar The base 31, and when the needle bar rotation motor 34 is gradually accelerated and reaches a high speed, the roller 36 reaches the actuation section 35 of the needle bar cam member 35 and moves relative to each other as shown in FIG. Accordingly, the roller arm 361 is rotated to rotate the needle bar base 31 via the link body 362, whereby the needle bar 12 also rotates. The drive of the needle bar rotation motor 34 continues until the roller 36 is disengaged from the actuating segment 354 and reaches a stop position of the other non-actuating segment 353. As shown in Fig. 13, when 01 is detected by the original sensor, the reference preparation position of the non-actuating section 352 of the cam portion 351 is caught, and the boundary between the non-actuating section 352 and the active section 354 is bordered. In the fourth degree, the stop position S2 is preferably controlled such that the transition from the boundary K2 between the active segment and the non-actuating segment (5) to the stop position S2 is equal to the angle. 23 201245528 S2 : Body ground, when the needle bar (10) is rotated next, the stop position 仏疋 is rotated as the preparation position of the rotation start position = direction, so that by setting the action segment 3 = non-compact: 3 The angle between the boundary Μ to the stop position S2 is equal to, and the angle is equal. When the roller 36 enters the actuation section 354 from the non-actuated section, the needle bar rotates the motor 3 in a high speed state. In the case of using the needle bar cam member 35, the needle is in a stopped state and cannot be actuated when the roller is in the non-actuating segment 352 or the running direction _, so that the needle bar is The rotation of 12 must be controlled at a more accurate time point to obtain a more accurate time point, the needle (four) moving motor 34 is controlled to be earlier than the starting point (four) of the rotation, such as starting the running and pulling mechanism such as the 14th and As shown in Fig. 15, the wire pulling mechanism 50 is disposed lower than the needle plate 14 in the machine tool portion 1Gla_, and (10) pulls the wire to pull the lower wire. The wire pulling mechanism 5G includes a pull line that pulls the bobbin case from the hole 15 of the needle plate 14 to change the button piece, and the wire drawing operation of the wire drawing member 51拉, the cable cam member 53, actuated by the wire motor 52, receives the roller 54 (pull follower) actuated from the cable cam member (10), and pulls the self-bribery wheel (10) off the line. Power is transmitted to the wire link mechanism 55 of the wire member 51. The link mechanism 55 includes a roller arm 541 and a yoke 542. The wire drawing motor 52 is in a state in which the output shaft of the motor mounting base 52 attached to the machine tool portion 1 is vertically upwardly oriented, and a driving gear is disposed on the output shaft of 24 201245528. 522. On the upper surface of the motor mounting base 521, a small diameter driven gear 523 is disposed adjacent to the driving gear 522, and the gears mesh with each other, and the speed increasing rotational force is transmitted from the driving gear 522 to the driven gear 523. . The driven gear 523 is coupled to the wire cam member 53' via a rotating lever 524, and the rotational force of the driven gear 523 is transmitted to the wire cam member 53. As shown in Fig. 16, the wire cam member 53 is shown. There is a substantially fan-shaped shape, and a substantially curved outer edge portion becomes a cam portion 53 which is in contact with the roller 54 and displaces the roller. The cam portion 531 has arc cam-shaped non-actuating segments 532 and 533 which are fixed at a fixed distance from the center of rotation, and an actuating portion 534 between the two non-actuating segments 532 and 533 is formed continuously with the non-actuating segments. Both of the two non-actuating segments 532 and 533 have a cam shape that maintains a fixed distance from the center of rotation, however, the diameter of the non-actuating segment 533 is set to be larger than the diameter of the non-actuating segment 532. The actuating section 534 has a cam shape having a diameter that gradually increases from the boundary of one of the non-operating sections 532 and a diameter that is equal to the non-actuating section 533 at the boundary with the other non-actuating section 533. Specifically, the wire cam member 53 has a cam portion 53 1 including the non-actuating segments 532 and 533 which are continuously formed without urging a wire to the wire member 5, and The wire is operative to apply the actuating section 534 of the wire pulling member 51. The wire pulling mechanism 50 rotates the wire pulling member 25 201245528 51 in a fixed direction during a predetermined angle range of the upper rod angle during the sewing period, and at the time of the other upper rod angle range The wire member 51 is rotated in the opposite direction in the same angular range as the foregoing range. Therefore, the more the blade speed is, the more the wire member 51 has to be rotated in each direction at a high speed. Therefore, as the needle bar rotating mechanism 30, the wire cam member 53 is designed such that the cam portion 53 of the wire cam member 53 is provided with a non-actuating segment brother 533 'the non-actuating segment 532 or 533 is set as A ready position of the roller 54 and the roller motor 52 are sufficiently accelerated during the relative movement of the roller 54 during the non-actuating segment 532 or 533 as the running-in period, the roller relatively moves along the actuating segment 534. According to this, the high-speed rotation of the wire pulling member 51 can be performed only by the high speed range of the wire drawing motor 52. The wire pulling member 51 reciprocates, however, unlike the needle bar 12, the wire pulling member 51 temporarily stops between the forward rotation and the backward rotation. Further, unlike the needle bar cam member 35, the wire cam member 53 is not designed such that the wire pulling member 51 reciprocally rotates to one side according to the rotation of the wire cam member 53, and the wire is reciprocally rotated. The member 51, the cable cam member 53, also has to be rotated back and forth. Therefore, one of the non-actuating segments 532 is for the running-in period when the cable cam member 51 is rotated forward, and the other non-actuating segment 533 is for running when the cable cam member 51 is rotated backward. period. According to this, the wire pulling member 51 can perform forward rotation and backward rotation at higher speeds, respectively. For example, the needle bar cam member 35, the wire pulling mechanism 50 can also be configured such that the mechanism is provided with an original sensor to detect the reference position of the wire cam member 53 and the position of the wire cam member 53 begins. The rotation is made from the reference preparation position to rotate the wire cam member 51 when the wire drawing motor 52 reaches a high speed state. The roller 54 that is in contact with the cam portion 531 of the cable cam member 53 is rotatably held by an arm portion 541a (bell crank) of the roller arm 541, and the wire pulling member 51 is held by the roller arm. The other arm 541b of 541 is on. The base end sides of the two arm portions 541a and 541b of the roller arm 541 are rotatably supported by a pivot shaft 542 provided on the motor mounting base portion 521. The roller arm 541 is energized by a torsion helical magazine 543 such that the roller 54 is constantly in contact with the cam portion 531 of the cable cam member 53. A stopper 544 is provided following the roller arm 541 to prevent the cable cam member 53 from being excessively passed by the torsion screw 543 when the cable cam member 53 is excessively rotated and the roller 54 is detached from the cam portion 531. Turn. The base end portion of the wire pulling member 51 is held on the rotating distal end portion of the arm portion 541b of the roller 541, and the distal end portion of the wire pulling member 51 extends toward the hole 15 under the needle plate 14. The distal end side of the wire pulling member 51 is a free end and is formed in a sharp shape. The wire pulling member 51 is generally in a prepared position with its distal end portion in front and away from the hole 15, and for the wire drawing operation, the distal end portion moves directly below the hole 15 and through the hole from the bobbin case The lower line of 15 is connected to pull the lower line back. On the left side portion of the needle plate 14, a guide member 511 is provided which supports the plate-shaped wire pulling member 51 to insert the wire pulling member into a gap between the upper and lower plate bodies before and after the rotation. And preventing the wire pulling member 51 from vibrating in the up and down direction when rotated. 27 201245528 In the above configuration, in the wire drawing machine (10), when the wire pulling device 54 is driven in a state where the cam portion 531 of the wire cam member 53 is in a non-532-predetermined preparation position, The wire projection 53 is rotated by the drive gear 522 and the driven gear 523. When the wire drawing motor 52 starts driving the day (four) low speed _, the roller moves relative to the non-actuating section 532 of the wire cam member 53 so that the heart force is not applied to the wire pulling member 5 and when the wire drawing motor 52 When the gradual acceleration and reaching a high speed state, the roller 54 reaches the actuation section 534_M of the cable cam member 53 to move. According to this, the roller arm (4) is rotated to rotate the wire member 5, whereby the wire member 51 is rotated forward, and the distal end portion thereof is directly under the hole 15 and the lower wire is pulled backward. The pull motor 52 continues to drive until the roller 54 disengages from the actuating section 534 and reaches a predetermined stop position of the other non-actuating section 533. Specifically, the control device 90 controls the wire drawing motor 52 such that the wire drawing motor 52 accelerates the engagement with the non-actuating section 532 of the same-slave member 5 cam member, and the wire drawing motor 52 acts thereon. The segment 534 is driven at a high speed. The wire member 51 has to be rotated backwards and returned to the original position, so that in the wire pulling mechanism 50, when the wire drawing motor 52 is in the preparation position from the roller 54, it is in the non-actuating segment. When the state of one of the stop positions of 5 3 3 is reversed, the roller 54 is relatively moved along the non-actuating section 533 at a low speed state when the pull motor 52 starts driving, and when the pull motor 52 reaches one Relative movement in high speed state. According to this, the roller arm 541 is rotated in the opposite direction, and the wire pulling member 51 is rotated backward. 28 201245528 The pull motor 52m_ moving straight (four) roller 54 is the active section 534 and reaches the original squaring position of the non-actuating section 532. Specifically, the non-actuating sections 532 and 533 of the cable cam member 53 are respectively formed on both sides of the sandwiching (four) moving section 5 3 4 . The control device 1卯 controls the wire drawing motor 52 such that the wire drawing motor 52 starts driving at the non-actuating & 532 or 533 of the wire cam member 53, and after the wire motor 52 is sufficiently accelerated, the motor is driven at 4 534 is applied - the wire is used as the power material pulling member 5, and as shown in Fig. 17, when S3 is a predetermined preparation position of the roller 54, the preparation position S3 to the non-actuating segment 532 and the The (10) degree Θ3 of the boundary K3 between the actuation sections 534 is set such that the cable motor 52 can reach a high speed state at the boundary rule 3 when the recording motor 52 is driven from the ready position S3. When the 5th pull wire member 51 is rotated forward, the roller stop position S4 of the non-actuating segment 533 becomes a ready position 'as a backward rotation start position of the wire member $1, so that from the preparation position s 4 to The angle of rotation Θ4 of the boundary K4 between the non-actuating section 5 3 3 and the actuating section 534 should be set equal to the angle of rotation Θ3. In the wire pulling mechanism 50, by considering the running-in period of the relative movement of the roller 54 on the non-actuating segment 532 or 533, the wire drawing motor 52 must start driving the wire early before the start of the planning drive. Run-in period. As shown in FIG. 1 , the cloth moving mechanism 80 includes a holding frame 81 for holding a workpiece (cloth) on the upper surface of the machine tool portion 1b, and supporting the holding frame 81 for moving up and down. The support arm 82, as shown in Fig. 19, moves the X-axis motor 83 of the holder 81 in the X-axis direction via the support 29 201245528 support arm 82, and as shown in Fig. 19 via the support arm 82 The Y-axis direction of the holding frame 81 is moved by the Y-axis motor 84. In this configuration, the cloth moving mechanism 80 can move and position the cloth on an XY plane via the holder 81 to move the needle down to a specific position on the cloth for each stitch (each stitch) Formed to form a free seam. Specifically, the cloth moving mechanism 80 (-cloth moving mechanism) moves the cloth along the horizontal plane to perform the stitching work at the stitch point on the cloth. As shown in Fig. 18, the tightening device 70 includes a tightener 79 for applying a tightening force to the upper thread, and a tightening solenoid valve 71 as a tightening actuator, which can be changed. And adjusting the tightening force applied by the tensioner 79. The wire tightener 79 is disposed on the right side surface of the arm portion 101a, and is clamped to the upper line of the path from the line supply source to the jumper and applies a tightening force thereto. The tensioner 79 includes two tight spools 72 for clamping the upper thread, and a hollow supporting the tight discs 72 to move in the X-axis direction so that the tight discs 7 2 are close to each other and separated from each other. a pivoting rod 73, a push rod 74 extending through the inner side of the hollow pivot shaft 73 and pushing one of the tensioning discs 72 against the other tensioning wire tray 72, a jumper magazine 75, and a receiving and holding member The body shell 76. On the other hand, on the left side of the tightener, the tightening solenoid valve 71 is disposed such that an output shaft 71a is aligned with the push rod 74, and the output shaft 71a generates a thrust in the extending direction based on a supply current value. The output shaft 71a is coupled to a transfer rod 78 that is inserted through a coil spring 77, and the transfer rod 78 is inserted through the coil spring 77. The coil spring 77 pushes 30 201245528. The output shaft 7la is pushed in a push-back direction. The output shaft. Therefore, when a current is not supplied to the tightening solenoid valve 71, the wheel shaft 71a is pushed back by the coil spring 77, and the thrust for pushing the push rod toward the tension disk 72 cannot be obtained, so The two tensioning discs 72 are in a free state, and no tightening force is applied. When a current is supplied to the tight solenoid valve 71, the output shaft 7U is pushed out by the thrust corresponding to the supplied current value. The transfer rod 78 pushes one of the wire spools 72 against the coil spring 79 via the push rod 74, and according to the thrust, a force can be applied to the upper thread between the two wire spools 72. The current supply amount of the solenoid valve 71 is controlled by the control device 9〇, and the wire tightening device 70 can apply a proper tightening force to the upper wire. The control device 90 controls the actuating actuator as a tight line. The tight line solenoid valve 71 can reduce and adjust the tightening force when the slotted direction calculated by the drawing of the pull wire or the formation of the stitches including the stitches belongs to the section Mb. The control device is as shown in Figure 19, d Xuan slitting machine 1 令 令 - control device 90, its control The operation of the respective parts and components.

For the sake of convenience, the description of the upper line U of 拎L will be omitted. When a cloth is moved by the cloth moving machine 32 201245528 according to the sewing material for each green & stitch formation 80, 'according to the feeding direction, that is, the stitch forming direction, when the needle 11 penetrates the When the cloth is passed, the winding direction of the thread U passing through the needle hole 11a of the needle 11 and the needle 11 is wound into the left winding direction as shown in Fig. 2A or becomes rightward as shown in Fig. 20B. The direction, and depending on the winding direction, will determine whether a complete stitch or a twisted stitch will be formed. As shown in Figs. 21A and 21B, depending on whether the needle 移动 is moved downward relative to the lower line D on the left side 1 or the right side R of the path, it is also determined whether a complete stitch or a stitch is formed. Next, the relationship between the direction in which the cloth is moved and the occurrence of a winding stitch will be described with reference to Fig. 22, using an example of a half hook in the sewing machine 100 according to the present embodiment. In Fig. 22, in the entire angular range (360 degrees) in which the cloth is fed by the cloth moving mechanism 8 around the hole 15, the angle range is the possibility of the occurrence of the winding stitch and the winding stitch Factors to identify. First, the angle range I of the feed direction is an area that is unsure that the needle 落 is falling (downward) to the right of the lower line passing through the hole or to the left side, because the cloth is at this angle range In the direction of the feed, the direction substantially matches the direction of the lower wire from the bobbin case toward the hole 15, and is the area where a complete stitch or a stitch may occur. On the other hand, in this region, the direction in which the upper thread is wound with the needle 11 is constant depending on the feed direction, so this region is affected by this factor. Secondly, regarding the angle range H, when the cloth is fed into the angle range in the direction, the needle 丨丨 can be surely moved underground to the left of the lower path of the shuttle 15 (the bobbin case) extending to the hole 15 And the direction in which the upper thread is wound with the needle n is rightward according to the feeding direction, so the winding of the 2012 20122828 is surely formed in this area. Secondly, regarding the range πι, when the cloth is fed into the angular range in the direction, the needle 丨丨 can be surely moved underground to the left of the lower path of the hole 15 from the shuttle (boiler casing), however Since the direction in which the upper thread is wound with the needle 11 is uncertain, a complete stitch or a stitch may occur in this area. Regarding the range IV, when the cloth is fed into the angular range in the direction, the needle 11 can be surely moved underground to the right of the lower path of the shuttle 15 (the bobbin case) extending to the hole 15, and the upper line is The direction in which the needle 11 is wound is to the left 'so that a complete stitch can be surely formed in this area. Prevention of the control of the winding stitches Therefore, in the sewing machine 100, the formation of a complete stitch or a winding stitch is dependent on two factors, that is, the needle 11 is connected to the hole from the shuttle (bobbin case). 15 the lower line path falls to the side of the hole 15, and the direction in which the upper line is wound with respect to the needle pin, and in the region where these factors are uncertain, the nature of the stitch may also become an indeterminate part. . Therefore, in the sewing machine 100, the angle ranges 1 to 1 ¥ of the four segments identified and set based on the possibility of the stitching and the stitching factor are recorded in the data memory 94. Further, as shown in Fig. 23, for the angle V of each segment, it is shown that the wire drawing operation with the wire pulling mechanism 5 turns or the needle bar rotation of the needle bar rotating mechanism 30 is performed. The data is stored in the data memory (storage unit_) in the form of tabular data. Specifically, the control device 90 includes a storage unit that stores each segment [to IV ' the wire drawing operation of the wire pulling mechanism 5G or The needle rod rotating mechanism % of the needle 34 201245528 is only capable of rotating the operation (4) indicating the command, wherein the entire angular range of the feeding direction of the upper and lower moving paths is adjusted around the needle 丨丨 and the needle bar 12 by means of The possibility of winding the stitches and the factors of the winding stitches are divided into several sections according to the classification of the angle range. 5 The Xuan control device 90 performs the following control operations for preventing the stitching during the seaming operation. Specifically, Forming a sewing pattern, and when the amount of movement of the X-axis motor 83 and the γ-axis motor 84 for a stitch is read from the auxiliary material or the movement amount from the 6 «axis direction and the Y fiscal direction, one of them is recognized. Angle range 1 to 1V for this The section to which the moving direction belongs. Thereafter, depending on the identified section, whether or not to perform the wire drawing operation or the needle bar turning operation is determined by the table data, and (4) the wire mechanism 5_the reduction motor 52 or the needle bar rotation mechanism needle (4) The moving motor 34 performs each operation corresponding to the lever (four) angle (upper shaft shaft) corresponding to each execution time point. The X control device 90 determines a stitch point from the sewing material (the needle penetrates into the 4 cloth) Position) or cloth movement amount calculation when the needle is worn by the cloth (at the time of the suture line) with the cloth moving mechanism 8 〇 the cloth moving direction, and the recognition angle range 1 to 1V is the cloth moving direction Section - The control device 9 performs the wire drawing operation of the wire pulling mechanism 5 () when the moving direction belongs to the angular range (the first angle dry circumference), when the moving direction is 30 4 (the second angle range) is performed when the needle bar rotation mechanism needle bar rotation operation is performed, and when the movement direction belongs to the angle range _ (the first movement f·), the line is performed by the thread taking mechanism 5G and the needle The needle bar of the rod rotating mechanism 3G rotates. The control is placed 9 stitches according to the seam Spinning data determined - stitch point or cloth movement 35 201245528 Stem 'counting different for each line of mobile machine lion cloth moved here, defining the first angle range βσΠ, the second. Different from the third angle range The angle range data can also be; first: '定::1: in the material, and the control device 90 controls the needle bar to rotate and pull according to the data. Specifically, the control device 9 moves as each stitch is moved by the cloth The movement direction of the machine lion belongs to the first-angle range, and the wire drawing operation of the wire pulling mechanism 5 is performed, and the needle bar rotation operation of the needle bar rotation mechanism 30 is performed when the angelica is in the range of 4 degrees. The time point at which the needle bar is rotated will then be described with reference to Fig. 24 to prevent the winding stitch control from performing the appropriate time point of the needle bar rotation. In Fig. 24, the upshift segment 'until the needle tip reaches the top dead center of a needle bar after being removed from a workpiece, b*k. moves down & until the d needle tip reaches the top dead center of the needle bar Up to the workpiece, c segment. Move down the segment until the needle tip reaches the bottom dead center of the needle bar after reaching the workpiece, and the d segment is moved up until the needle is engaged with the hook from the bottom dead point of the needle bar. Section e. Move up the section until the needle comes out of the workpiece after the needle and the hook are engaged with each other. When the needle bar is rotated, it reaches the needle insertion angle shown in Fig. 24, that is, the needle of the paragraph a 2012 201245528, the orientation of the needle u needs to be rotated - the necessary angle. Therefore, the needle bar rotating horse of the dry motion mechanism 30 is controlled to reach the needle corner household: the two points start driving at least for a certain period of time, until the reference from the needle: : the non-actuating section 352 or 353 of the member 35 The preparation position reaches the middle position of the actuation 1^354.

D /,, the orientation of the needle 11 is at least until the needle and the shuttle cooperate with each other = the upper rod angle, that is, before reaching the bottom dead point of the e-segment: the cup angle Back to the original position. The needle bar rotation motor 34 performs a cooperative operation on the non-actuating section 352 or 353 of the face bar cam member 35 and advances the high speed reciprocating rotation of the needle bar 12, so that the orientation of the needle u is reached by setting the start time The rotation of the needle angle before the necessary angle ' can prevent the delay of returning to the original orientation of the needle u. The time point of the pull line Next, the appropriate time point for performing the pull wire operation for preventing the stitch control will be described with reference to the figures 25 to 27. In Fig. 25, the line connecting the black triangles represents a needle bar curve, the line connecting the black squares represents a shuttle curve, and the line connecting the black diamonds represents the _ jumper curve. As shown in Figures 26 and 27, the wire pulling member 51 traverses the bore 15 where the stitch point is located, and in order to perform the wire drawing operation, the forward rotation of the wire pulling member 51 is preferably at an upper rod rotation angle ( The upper rod angle is a few of the 113 degrees of the needle insertion angle. Therefore, the wire drawing motor 52 of the wire pulling mechanism 5 is controlled to start driving at least a certain time later than the time point of reaching the needle insertion angle of 37 201245528 until the reference from the non-actuating section 532 of the wire drawing cam member 53 The preparation position reaches the stop position of the non-operating section 533. The rearward rotation of the cable member 51 is preferably performed at an upper rod angle of 27 degrees, which is the upper thread opening angle, where the upper thread is disposed farthest from the needle center by the shuttle. 0, the wire pulling mechanism 50 is controlled to start 'to enable the transition from the non-actuating segment of the wire & wheel member 53 to the actuating segment 534. The degree is no degree) can cooperate with each other. As shown in Fig. 35®, the displacement H of the pull cam 53 is the maximum (four) ' before the human needle angle is (1) degrees, and accordingly, the pull cord configuration is rotated forward. The maximum position g__(10) of the position (4) of the wire cam 53 continues until the upper line opening angle is 27 G degrees, and thereafter, the displacement h of the wire yam is reduced. Specifically, the wire member 51# is rotated backward when the upper wire opening angle is 27 degrees and returns to the original preparation position when the upper wire opening angle is a twist. Specifically, by setting the displacement of the wire cam 53A, the wire pulling operation can be performed at the above-mentioned time of the field without interfering with the needle and the upper thread. The definition of the line type in Fig. 35 is the same as that in Fig. 25. - the time of the forward rotation and the backward rotation of the heila wire member 51 needs to be reduced, and the running motor is reached at the high speed state of the hybrid motor 5 2 after the surplus motor is operatively engaged in the non-actuating section 532 or 533. Therefore, the wire pulling member 51 can be rotated at a high speed, and can sufficiently satisfy the demand for short-time work. For convenience, the description of the upper line (10) is omitted. 38 201245528 Wire tension adjustment control during wire drawing As shown in Fig. 28, when the wire drawing operation is performed, the lower wire 8 is pulled by the wire pulling member 51 and the path length thereof is long, and the lower wire D is self-owned. Pull out the bobbin side. For the sake of convenience, the description of the upper line ^ is omitted. Therefore, even when the upper thread tension is set lower than the normal value, the upper line of the upper blood line can be the upper side of the outer cloth, and the stitch having a lower tension and a good tightness can be used. Therefore, the tightening solenoid valve 71 is controlled to reduce the tension of the wire at the same time as the sewing thread to be executed to determine the wire drawing operation. At this time, the thread tension of the tightening solenoid valve 71 is automatically calculated by automatically deducting the predetermined amount from the line tension setting value set by the slitting data, or automatically reducing it by a predetermined ratio, or applying In the wire drawing operation, the thread tension is the consumption state and (4) the wire tension is added to the wire tension value which is suitable for the wire drawing operation during the wire drawing operation. Therefore, the control of reducing the tension of the wire by the simultaneous pulling operation of the wire can make the stitch of the wire drawing work coincide with the stitch tightness of the wire drawing operation. 'Control operations to prevent winding stitches These operations will be explained with reference to Figure 29. When the sewing operation is performed in accordance with the sewing material, the control device 90 of the sewing machine 100 reads the sewing material from the sewing material in the case where the rotation degree (minus) of each rotation of the upper lever is a reading-like reading degree. The amount of movement in the X-axis direction and the gamma direction is for the formation of the next stitch (step si). Thereafter, the control device 90 calculates the cloth moving direction, that is, the sewing direction, from the movement of the X-axis direction and the γ-axis direction 39 201245528 (step S2). Therefore, the control device 90 has a function of the determining means for performing a step of determining the direction in which the cloth of the cloth moving mechanism 80 moves (sewing direction). Next, the control device 90 determines, by the table shown in Fig. 23, whether or not the slit direction calculated by the angle a is a range of the angle range I or Η (the first angle range) (step S3). Specifically, the control device 9 has a function of the identification means for performing step S3 to identify a section containing the direction of movement determined by the decision means. Thereby, when the sewing direction belongs to the section of the angle range 丨 or ^, the control device controls the tightening solenoid valve 71 such that the line tension is lower than the set value or equal to a predetermined low tension value (step S4). And, by monitoring the upper rod angle according to the detection signal of the decoder NP, the control device can start driving the cable connection 52 at an appropriate time to perform the wire drawing operation (step S5). According to this, even when the sewing direction belongs to the section of the angle range of 1 or 11, the needle is moved down on the right side of the lower line, and the complete stitch can be completed. The appropriate time point differs depending on the rotational speed of the upper rod, and in this example, the upper rod rotation angle is set to 100 degrees. In step S3, if the sewing direction does not belong to the section of the angle range of 1 or 11, it is judged whether or not it belongs to the section of the angle range ΙΠ (step S6). According to this, when the sewing direction belongs to the section of the angle range m, the driving of the needle bar rotation motor 34 can be started at an appropriate time point by monitoring the upper rod angle according to the detection signal of the decoder NP. The rotation of the needle bar 丨 2 (step S7). According to this, the upper thread can be entangled with the needle on the left side of the needle 11 40 201245528, νο and the sewing operation of the complete stitch can be completed. In step S6, when the seaming direction does not belong to the section of the angle range, 'the seaming direction is the zone drawing operation belonging to the angle range IV and the needle bar rotation operation, and the normal stitch shape is performed. The control device 90 has a movement direction determined by the control device = set 3), and the wire drawing operation of the wire pulling mechanism 50 (the wire drawing motor 52) or the needle bar rotation machine is controlled by the control 7' The needle bar rotation of the needle bar rotation motor 34) is performed or V-execution', that is, according to the movement direction of the determination device (step ^ and the movement direction, the wire pulling mechanism 50 (wire drawing motor) is selectively executed) The wire drawing operation or the needle bar rotating mechanism 3Q (the needle bar rotates the motor needle bar to rotate the control device. Advantages are as described above, in the seam cutting machine, the stitching direction of each stitch can be obtained, and according to the stitching In the young direction, the wire drawing operation or the needle bar rotation operation can be selectively performed. Therefore, it is possible to prevent not only the winding stitch caused by the one stitch point with respect to the lower thread but also the winding of the upper thread and the sewing needle U. Adding stitches caused by the direction, and reducing the addition more effectively The incidence of windings. In addition, the seaming machine can cope with most factors, so that even if you use a variety of different shuttles such as vertical shuttle, horizontal shuttle, full hook and shuttle, you can prevent the winding. In the seam young 0, following the execution of the wire drawing operation, the control of the cutting tension is simultaneously performed, so that the tension of the lower thread pulled out by the wire drawing work is well balanced with the upper thread, and the The knot can be pulled into the cloth, and the line tightness can be improved by 41 201245528. (4) When the tension is applied, the rotational force is given to the _ line cam member 53 and the rotational force is applied. 35: non-actuating segment, and arriving at The action two: =:= nine. The operation 'so the wire drawing operation and the needle bar rotation work can be like 1 : and these operations can not reduce the seam _ motor heart; the second example of the needle bar rotation mechanism will refer to The second example of the 30th to 32th _ needle bar rotation mechanism. In the second example, the needle bar rotation mechanism is the same as the above-mentioned needle (4) engine 3 是以, and the same reference numerals are used, and the repeated explanation is given: The needle squeezing member includes the needle bar rotating mechanism 30A as one end cam The needle bar cam member 35A of the motor 2 is driven to the needle bar by the rotational force of the roller 36A (the needle bar rotating follower) and the j roller 36A applied from the needle bar cam 35A. 12 and the rod-producing link mechanism of the needle bar base η, and - for directly - shifting the power from the roller 3 from the side of the transfer needle bar 12 to the interruption (four) The device 34A (for example, a gas rainbow or a solenoid valve). The link mechanism includes a roller arm 37A, a first link body 382, a second link body 383A, an arm portion 384A, and an arm portion 386. And - the link body 387A.

to one end of the second arm portion 372A, and the roller 36A is rotated. The old "eighth" needle bar 12 side. The other end portion of the actuation link and coupled to the first link body 382A is coupled to the body 381A, and is coupled to one of the push rods of the actuator 34A and the one end portion of the second link body 383A. The second link body 3 83 A of the arm body is coupled to a 384A of a bell crank which is axially supported by the shoulder screw 385A and the other arm of the bell crank The 386A is coupled to the needle bar base 31 via the transmission link 387A. In Fig. 30, the actuator 34A is in a state of withdrawing the push rod. In this state, when the needle bar rotating cam 35A is in accordance with the upper rod When the rotation of the rotation of 22 is rotated, the roller 36A changes its position in the Y-axis direction according to the displacement of the cam surface, and the entire roller arm 37A rotates around the shoulder screw 374A. Thereafter, when the roller arm 37A rotates The first and second link body buckles 2-8 and 383A transmit a rotational force to the bell crank. Accordingly, the needle bar The base 31 and the needle bar 12 are rotatable via the transmission link body 387. 43 201245528 On the other hand, the second arm portion 372A of the roller arm 37A and the first link body 382A have the same length set, and When the direct acting rod of the actuator 34a protrudes forward, as shown in FIG. 31, the rotational joint portion of the first link body 382A and the second link body 383A and the center of rotation of the roller arm 37A ( The shoulder screw 374A of the rotation joint portion is overlapped. In this case, even if the roller arm 37A is rotated about the shoulder screw 374A by the needle bar rotation cam 35A, the power is not transmitted beyond The first link body 382A' is configured such that the needle bar 2 can be in a fixed state. Specifically, the link mechanism is configured to rotatably couple the first link body 382A to the second link The rotation coupling portion of the body 383A (the rotation coupling portion of the needle bar link body) is displaced to a position concentric with the rotation coupling portion of the roller arm 37A (the rotation coupling portion of the other needle bar link body) The force from the roller 36A cannot be transmitted to the needle bar. The forward and retraction of the direct acting lever of 34A can be controlled by the controller 90, and by controlling the actuator 34, the needle bar can be freely rotated or formed to be fixed. Specifically, the control device 90 controls the actuation. The slider 34A is configured to displace a rotary joint to a position concentric with the other rotary joint to rotate the needle bar or to fix the needle bar. The needle bar rotation mechanism 3A uses the upper rod 22 as a A drive source drives the "cup cup 12 so that the rotation of the needle bar 12 is fully synchronized with the overall actuation of the sewing machine 1 without delay. The second example of the wire drawing mechanism will be described with reference to Figures 33 and 34 for the second example of the wire drawing mechanism. 44 201245528 In the second example, the same components as the above-described wire drawing mechanism 50A and the above-described wire drawing mechanism 5A are denoted by the same reference numerals, and the repeated description is omitted. The wire pulling mechanism 50A includes a wire cam member 53A which is disposed as a -end cam on a rotating lever 531A which is rotated (actuated) by the slitting machine motor: 1 and a driving force applied by the wire cam member 53A. a roller (pull, spring follower), a driving force of the roller 54A is transmitted to the pulling member 51, a spring, a mechanism, and - from - the roller is transmitted from the power to The direct acting type actuator 52A (e.g., gas or electromagnetic reading) of the displacement between the state of the wire member 51 and the interrupted state. The cable cam member 53A is disposed on the rotary lever 5MA and rotates around the rotary cup 531A. The roller 54A is in contact with an end face similar to the wire cam member and is displaced according to the shape of the end face. The 〇海/衮轮 54A疋 is held by a first arm portion of the roller arm (bell crank) 55ia which is pivotable relative to the wall surface of the machine tool portion. "Hai Roller #551A includes one of the first arm and a second arm of the wrap- pivot as shown in Fig. 34. - A tension spring is coupled to the first arm of the roller arm 551A such that the roller 54 is in contact with the cam surface of the cable cam member 53A. One end portion of the link body 552A is coupled to the end of the second arm portion of the roller arm 551A to transmit the rotational force generated by the roller 54 to the wire member 51 side. The other end of the first connecting body 552A is coupled to an actuating displacement link body 553A coupled to the push rod of the actuator 52A, and is coupled to one end of a second link 45 201245528 rod body 554A. The second link body 554A is coupled to one of the arm portions of the bell crank 555A axially supported on the wall surface of the machine tool portion, and the other arm portion of the bell crank 555A holds the wire rod member. 51. In Fig. 34, the actuator 52A is in a state in which the push rod is withdrawn. In this state, when the wire cam 53A rotates according to the rotation of the rotating rod 531A, the roller 54A changes the position along the γ-axis direction according to the displacement of the cam surface, and the entire roller arm 5 51A surrounds the frame. The shaft rotates. Thereafter, when the roller arm 551 is rotated eight, the first and second link bodies 552 and 554 are transmitted to the bell crank 555A. According to this, the wire pulling member 51 is turned to the side of the hole 15, and the wire drawing operation can be performed. On the other hand, the second arm portion MiAa of the roller arm 551A and the first link body 552A have the same length set, and when the direct acting lever of the actuator 52A protrudes forward, as shown in FIG. As shown, the first link body 552A and the rotation link portion 556A of the second link body 554A overlap the rotation center 551Ab of the roller arm 551A. In this case, even if the roller arm 551A is rotated about the pivot by the roller 54A contacting the cable cam 53A, the power is not transmitted beyond the first link body 552A, and the wire member 51 is pulled. Will remain in the position shown in Figure 33. Specifically, the link mechanism includes the roller arm 551A, the first link body 552A, the second link body 554A, and the bell crank 555A. The link mechanism is configured to displace the first link body 552A and the rotation link portion 556A of the second link body 554A (the rotational link portion of a wire link body) to the roller arm The position of the center of rotation 551Ab of the 551A (the other 46, 201245528, the rotational link of the wire link body) is concentric, and the force from the roller 54A cannot be transmitted to the wire member 51. The control device 90 performs a wire drawing operation by controlling the actuator 52a to displace a rotational joint portion 556A to a position 'concentric with the other rotational joint portion 55] Ab. As shown in Fig. 35, the displacement Η of the wire cam 53A is the maximum displacement before the needle angle is 113 degrees, and accordingly, the wire member 51 is subjected to forward rotation. The state in which the displacement of the wire cam 53 is maximized continues until the upper lever opening angle is 270 degrees, and thereafter, the displacement η of the wire cam 53 turns. Specifically, the wire pulling member 51 is rotated backward when the upper wire opening angle is 270 degrees, and is returned to the original preparation position when the upper wire opening angle is a twist. Specifically, by the displacement of the wire cam 53 thus set, the lower wire can be pulled at the appropriate time point without affecting the needle u and the upper thread. In the example of the wire pulling mechanism 50A, the actuator 52A can also control the direct action lever to advance and withdraw by the pressing device 90, and the wire pulling member 51 can be freely rotated by controlling the actuator 52A. Or form a fixed. The needle bar rotating mechanism 5 0 A uses the sewing machine motor 2丨 as a driving source for rotating the wire pulling member 51 to rotate the wire pulling member 51. It is completely synchronized with the entire operation of the sewing machine 100 without delay. Third example of the wire drawing mechanism A third example of the wire drawing mechanism will be described with reference to Fig. 36. In the third example, the same members as the above-described wire drawing mechanism 50B are denoted by the same reference numerals, and the repeated description is omitted. 47 201245528 The wire pulling mechanism 50B includes a twisting motor 52B as a pull wire driving source, and a first link body (7) rotatable by the wire drawing motor 52B, one end of which is coupled to the first link The first link body 532B of a rotating distal end portion of the rod body 531B, and one end portion thereof are coupled to a third link body 533B of the mounting base portion 521B by a shoulder screw 534B. The second link body 5355 The other end portion is coupled to the other end portion of the third link body 533B. The wire pulling member 51 is fixed and held by the other end portion of the second link body 532b < 5H. In this configuration, the second link One end side of the body 532B is rotated along a circle by the first rod body 531B, however, the other end portion of the second link body 5326 is moved in an arc manner, and the radius of the arc is the first = According to this, the distal end portion of the wire pulling member 51 is deformed in an elliptical shape (see reference numeral M). Specifically, the wire pulling mechanism 50B includes the first link body 53ib and the second portion. The link body 532B and the third link body 5333 function as a pull wire coupling mechanism for transmitting power from the wire drawing motor 52Β The wire pulling member η is configured to revolve the distal end portion of the wire pulling member 51. The wire pulling member 51 is disposed such that the hole 15 is covered with the turning angle and the distal end of the (four) member 51 The threading operation is performed on the actuation section of the trajectory of the winding motion. Therefore, 'the case where the distal end portion of the cable member is rotated, only when the distal end portion of the wire member 51 is Close to the hole (10), the wire pulling member 51 will engage with the lower wire to retain the binding line. When the miscellaneous item is called the deviation correction (1), the lower axis will be separated from the recording member 54. Specifically, the wire pulling mechanism 5 (10) is borrowed. 48 201245528 = The range of the part of the winding movement path of the wire drawing member 51. According to this, unlike the example of the wire drawing operation by the reciprocating rotation, the wire member is rotated forward and backward (10) = need to pass the hunger Under the post, and in the _ phase material to meet the needs of the various components to avoid affecting the peripheral equipment, and compared to its sub-control can be less control of the operating time and the speed limit on the actual line. When the winding path of the wire pulling member 51 is determined in advance, the angle of the upper bar is also determined as the wire structure. (4) The time at which the lower line contacts and starts to pull the line. Therefore, when the angle of the rod corresponding to the start of the line is known, and the line motor is fine (4) before the angle of the upper rod of the red line is opened The driving is started at a predetermined angle, and the wire motor 52B is sufficiently accelerated as the running-to-run time from the start of driving to the start of the pulling line, whereby the wire cam member 53 having the above-described non-actuating segment is not required to be used, The wire drawing operation can be performed at a high speed state. Accordingly, the wire drawing operation suitable for high-speed sewing can be easily performed. Specifically, the control device 90 controls the wire drawing motor 52b so as to be miscellaneous when performing the wire drawing operation. The wire motor 52Β# the distal end portion of the wire pulling member (10) starts to drive outside the actuation section of the orbiting path 绕, and the wire drawing motor 52Β accelerates to the distal end portion of the wire pulling member 51 to reach the operating segment until. Third Example of Needle Bar Rotation Mechanism A third example of the needle bar rotation mechanism will be described with reference to Figs. 38 to 41. In the third example, the same member of the needle bar rotating mechanism 30 Β and the above-described needle bar rotating mechanism 30 49 201245528 is shown in detail, and the explanation is omitted. In the rod linkage mechanism, the needle bar cam member and the needle mechanism (which transmits the rotational force of the needle bar cam member 35B to the needle stem = the wheel structure of the needle county) The cymbal is different from that in the needle bar rotating mechanism 30. Specifically, the needle bar rotating mechanism _ includes a circular needle bar cam member 35B that is rotated by the belt driving force of the (four) needle bar _ motor 34, a cylindrical convex portion 36B (needle rod rotating follower) formed on the surface of the needle bar cam member 35BT, which includes the convex portion, and the arm portion is thin and includes a square member 362B (sliding member) on the arm portion 61B of the other arm portion a, an arm member 327B fixed to the vicinity of the thin upper end portion 311 of the needle bar, and - fixed to the upper end of the needle bar base b The portion 311 is a push cup 3358 above the arm member 3278. The cam arm 361B has a bell-shaped crank structure, and a rotational force from the needle bar cam member 35 is input thereto via the convex portion 36B. The arm 361B is rotatable and transmits the rotational force to the needle bar base 31. " Unlike the above-described roller arm 361, the convex The arm 36 汨 does not need to be provided with a torsion coil spring that constantly applies energy in a fixed rotational direction. As shown in Fig. 40, a cam groove 3516 is formed on the lower surface of the needle bar cam member 35B whose depth direction is the up and down direction. The cam groove 351B is formed by connecting five actuating segments 352B to form a continuous ring shape, and the actuating segments 352B apply a reciprocating rotational force to the needle bar base 31. Specifically, the action of the needle bar cam member 35B The segment 352 is formed in an angular range of 72 degrees. 50 201245528 The shape of the actuating segment 352B is such that its displacement is gradually increased from a starting point 352Ba at a minimum displacement position set at a minimum distance from the center of rotation of the sea, and A middle point 352Bb of the section becomes the maximum displacement, and then gradually decreases to a starting point 352Ba of the next actuation section 352B. In the needle bar cam member 35B, when the needle bar 12 is not rotated, the cam 361B The convex portion 363 is located at the starting point 35203, and is driven by the rotating and rotating the needle bar cam member 35B to move the convex portion 36B from this point to the starting point 3528 of the next operating segment 3528. At this time, the needle bar base member 31 is reciprocally rotated via the cam arm 361B. At this time, the needle bar cam member 35B is a grooved cam, so that the centrifugal force of the convex portion 3 can be prevented even when it is rotated at a high speed. The needle bar cam member 35B is disengaged and stable operation can be maintained. The cam groove 351B is a continuous arc-shaped circumferential cam and has a plurality of connecting portions formed without interruption. So that when the needle bar needs to be rotated to form a plurality of continuous stitches, the 4-needle bar cam member MB needs to be intermittently driven in each of the actuating segments, and the needle bar member is continuously rotated. Can be rotated several times. = This is different from (4) intermittent rotation that will be repeated and stopped. In the continuous rotation collar, it is not necessary to accelerate from the _stop state to form a stable linkage. Therefore, the cam groove 351A of the 4-pin cam member 35A is a ring-shaped projection 2' so that the timing belt 344 of the self-feeding (four) material is transferred to the needle-receiving cam member 35. Specifically, in the needle bar rotating mechanism 3, the needle bar cam member (5) 2012 51 201245528 reciprocally rotates within a limited angle range such that the timing belt (10) is only part of the key wheels 342 and 343. And only the material part is worn and easily destroyed. On the other hand, the needle bar cam member 353 has a cam groove measurement throughout the circumference so that it rotates in a fixed direction, and the timing belt 3 is engaged and completely uniformly worn, so that durability can be maintained for a long period of time. Not limited to this timing belt, the durability of the gear can be improved in the same manner even when the needle bar cam member is actuated by a gear. The original sensor 355B is disposed with the needle bar rotation motor 34 throughout the needle bar rotation mechanism. With the Wei, the output shaft of the needle bar rotation motor % is provided with a sensor 3, and by the original sensing (5), the presence or absence of the sensor 3 is detected, and the needle bar rotation motor 34 can be detected. Original location. In the control device 90, the start point 352Ba of each of the operating segments 352B of the needle bar cam member 35b can be made light by calculating the number of pulses from the original position of the needle bar rotation motor %. As shown in Figs. 41A and 41B, on the arm portion 361Bb on the side of the needle bar base 31 of the cam arm 361B which is a link body to receive the rotational force of the needle bar cam member 35B, a square member 362B is borrowed. A pivot 362 is rotatably supported about the z-axis. The square piece 362B has a square parallel-shaped tubular shape in plan view, and cooperates with the arm member 327B, and has a groove 327Ba which forms a groove portion and has a width equal to a width of one side of the square piece 362B. The needle rod linkage mechanism that transmits the rotational force of the convex portion 36B (the needle rod rotation follower) to the needle bar via the needle base 31 includes the cam arm (needle rod link body) 361B, the pivot A shaft 362Ba, the square member 362B (sliding member), and the arm member 327B. 52 201245528 The square piece 3628 can slide along the guide groove 327Ba and is attached to the guide groove 327Ba without being restricted in the up and down direction. The concrete member also has the square member Mm rotatably supported in the up and down direction by the pivot 362Ba while forming a predetermined gap to prevent the square member from coming into contact with the lower surface of the arm portion 36. The soil guide groove 327Ba is formed at the rotational distal end of the arm member 327B along the horizontal plane. By borrowing the trough money, the center line of the guide groove 3 2 7 B & passes through the needle bar base 3i_财心, and the base of the bar is _ rotation smoothly. The arm member 327B is fixed to the upper end portion 3U of the needle bar base 31 in a holding manner, and accordingly, when the cam arm 3 (10) is rotated, the rotational force is transmitted to the needle bar base 31 via the arm member 327B. At this time, the material fiber material material groove 3 is fully slid to maintain the connection between the cam arm 361B and the arm member 327B, and the rotation force is performed at a high speed state, when the cam arm MB and the arm are The friction between the components (4) between the components and the components in the up and down direction may cause vibration, abnormal noise, noise, etc., however, the square member 362B is not locked with respect to the guide groove 32 in the up and down direction. That is, the cam arm 361B is in contact with the arm member 327B and is not pinned to each other in the up and down direction. Therefore, the result of vibration or the like can be eliminated and the mechanism can be directly above the member 327B. The upper end portion 311 of the needle bar base & The push cup 335B is in contact with the bearing 323 via the cymbal 325, and slams the upper end portion 311, 53 201245528 of the needle county by the (four) side. The position of the arm member 327 and the link body 362 is prevented from being adjusted by the position of the arm member 327 and the link body 362 in the up and down direction relative to the spacer against the loading rod. It may cause friction and cause abnormal noise. (10), wherein the push cup and the arm member (4) are the positions of the (four) arm member 327Β: the whole to the appropriate height, the abnormality: the sound spitting needle bar cam member 35' the cam groove of the needle bar cam member The segment is a non-actuated distance from the center of rotation: == between the adjacent segments, and in the case of the needle (four) 34 open ^r: 4, 5 hai non-actuating segment can be utilized as The needle bar rotation motor 3 starts as a running-in segment when it starts to rotate by %. By adjusting the ratio of the 3H non-actuating segment to the actuating segment, the needle bar cam member 35B can be continuously rotated by one degree to perform continuous needle bar rotation synchronized with the up and down movement of the yoke u.印怡梦Q t ^ In this example, 'the control device 9 事先 reads the stitch point in advance from the slitting data stored in the data 4 or the data for forming the number of stitches = the amount of movement' and judges The control device 9G controls the needle bar cam member 35B to continue the miscellaneous rod cam member 35B after the needle bar is rotated to form the number of stitches. The depth direction of the cam groove of the needle bar cam member 35B is orthogonal to the direction in which the needle bar cam member 3_the convex portion (the needle bar cam member 35B is displaced in the radial direction thereof) is displaced, and For example, a deep cam groove having a depth of 54 201245528 degrees may be formed on the upper surface of the needle bar cam member 35B. Similar to the needle bar cam member 35A (the third), when the needle bar cam is formed into a chisel cam and is configured to rotate about the upper rod 22, the "cam groove and t is formed in the 4-needle cam member 35B. The outer circumferential surface of the outer ring is such that the taste direction of the cam groove is the radial direction of rotation. The roller member rotatably supported about the two-axis portion with respect to the arm portion 36 ma may be provided as a follower instead of the convex portion 36B provided on the arm portion 361Ba of the cam arm 36A. Fourth example of the wire drawing mechanism A fourth example of the wire drawing mechanism will be described with reference to Figs. 42 to 44. In the fourth example, the same components as those of the above-described wire drawing mechanism 5C are denoted by the same reference numerals, and the repeated description is omitted. In the wire pulling mechanism 50C, the configuration of the wire cam member 53C is different from that in the wire pulling mechanism 50. In Fig. 44, the wire cam member 53C has a substantially fan shape and is centered on a rotating lever 524, and a cam groove 5 is formed on the upper surface along a substantially curved outer edge portion. The cam groove 531C has an arc cam-shaped non-actuating section 532 (: and 533 (:, and between the _ _ non-actuating sections 532C and 533C) formed at a fixed distance from the rotational center position, and is connected to the non-actuating The segment of the segment 5340 is larger than the diameter of the other non-actuating segment 532C. The segment 534C has a cam shape with a diameter from the boundary of one of the non-actuating segments 532C. Gradually increasing, and at the boundary with another non-actuating segment 533 (: 55 201245528, the diameter reaches the same as the non-actuating segment 533C. A roller 54 that can be rotatably supported about the Z axis by a roller arm 541C (: is a configuration In the cam groove 531C, the cam groove 531c is displaced according to the shape thereof to the roller arm 541C. The roller 54 is displaced by the cam groove 531c (the direction is the rotation rod 524 around the wire cam member 53C). The direction of the direction of the cam groove 531C is the up-and-down direction orthogonal to the direction of displacement of the roller 54C. The roller arm 541C is axially supported by a pivot 542, and the element constitutes a link Mechanism 55C. The roller arm The 541C is structurally identical to the roller arm 54i except that the roller arm 541C supports the roller 54C under an arm portion 54i to correspond to the cam groove 531C that is open above the roller arm. The cable cam member The shape of the cam groove (1) of the 53C is such that the roller arm 541C can be dynamically applied, and the force is the same as the rotational force applied to the roller arm 541 by the cam portion 531 of the recording cam member 53C. In the mechanism 50C, the action of the roller arm 541C is locked by the cam groove, so that it is not necessary to provide the torsion coil spring 543 and the stopper in the above configuration, in the wire pulling mechanism 5〇C, when the wire drawing motor 52 When the drive starts, the green line (10) member 53C starts _, and the roller 54c accelerates in the non-actuating section 532C of the wheel groove 531C, passes the actuation & 534 (:, and stops at the non-actuating section 533 (:: According to this, the distal end portion of the 'hybrid member 51 passes under the hole 15 and stops. Next, the wire cam member 53C rotates in the opposite direction, and the roller 54C is accelerated at the non-actuating portion 533c to The high speed state passes the action: 56 2012455 28 534C, and stop again in the non-actuation section 532 (:. According to this 51 back to the original position. --------- before moving ~ the pull member 51 forward rotation is in the fiber $tu direction, Execution and backward rotation are performed after the needle is moved downward. _ Therefore 'the wire cam member 53C is a groove-shaped cam, and the pulley 54C can be prevented from being caught by the high-speed rotation (the wire follower 2) The force is released from the wire cam member 53C, so that stable operation can be maintained. The wire cam member 53C may be a circular cam member having a plurality of cam grooves formed in a continuous annular shape so that the wire member member can be reciprocally rotated back and forth as the above-described needle bar cam member 35B. In this example, the cable cam member 53C is driven to rotate in a fixed direction. When the cable cam member is constituted by the connecting cam groove as described above, a convex groove is set as a-return wire actuating unit, and the towel brim wheel is gradually increased by a non-actuating segment 532c having a small diameter from a small radius. To the non-actuating section 534C with a large radius of the non-actuating & 533C, and further returning to the non-actuating section 532c having a small radius via the gradual reduction of the diameter of the J, and by connecting a plurality of the actuating units, Forming a continuous annular cam member. As described above, the §-circumferential cam is formed by forming a continuous annular cam groove = the cam groove of each of the pull-type actuating units is formed without interruption. Therefore, when the wire drawing operation is required for forming a plurality of continuous stitches, the wire cam member 5 3 C does not require a door rest and reciprocates to rotate 'and the continuous rotation of the wire cam member 5 is redundant, and the V-drawing can be performed. Line work. Therefore, the continuous wire drawing operation is performed, and there is no need to accelerate the operation in each operation, so that stable continuous operation can be performed. 57 201245528, when the Tianhe Haila line cam member 53C is a circumferential cam, the example of the fan 1 cam can be eliminated. The drive gear 522 and the driven wire 523 use only 4 knives and the gears 522 and 523 All the teeth are each other. The teeth are evenly worn to maintain long-term financial performance. Even if the ridge wire cam member 53C is moved by the timing belt, the belt can be improved in the same manner. When the wire drawing operation is continuously performed for forming the number of stitches, the control device 9 controls the far-wire cam member 5 3 c to read the secret information from the data block in the data recording body 94 in advance. After the point data or the chord is formed to move the member I of the number line, and it is judged whether or not the wire for forming the number of stitches continues, the wire cam member 53C can be used. Like the above-described wire cam member 53A, when the wire cam member 5 which is a groove-shaped cam is again placed on the rotating rod which is disposed in the horizontal direction and can be fully rotated, the cam groove of the radial direction of the depth riding It is preferably formed on the outer circumferential surface of the wire cam member 53A.
