The present invention relates to an embroidery robot that can be performed in a targeted manner. Background art
従来、 例えば、 刺繍用ミシンおいて、 色糸の供給及び糸通しは人手を介 して行っていた。  Conventionally, for example, in an embroidery sewing machine, supply and threading of colored threads have been performed manually.
ところで、 この色糸の供給及び糸通しは、 ミシンを停止しなければなら ず、 特に、 色糸の交換作業は、 1台の刺繍用ミシンに通常数頭程度から多 い場合には 3 0頭程度備えられるミシンへッドの各々について色糸の掛け 替え作業を行う必要があることから、 ミシンの停止時間が数時間にも及ぶ こととなる。 したがって、 ミシンの稼働率及び生産性を向上するため、 ミ シンの稼働中に色糸の交換作業を行うようにできるようにすることが要請 されていた。  By the way, the supply and threading of the colored thread must stop the sewing machine. In particular, the replacement work of the colored thread is usually 30 to 30 when one embroidery sewing machine usually has several to many. Since it is necessary to change the color thread for each of the sewing heads provided to a certain extent, the stopping time of the sewing machine may be several hours. Therefore, in order to improve the operation rate and productivity of the sewing machine, it has been demanded that the color thread can be changed during the operation of the sewing machine.

この場合において、 カッター 7 1は、 ロータリーソレノィ ド 7 1 aによ つて駆動させる可動刃 7 1 bと、 固定刃 7 1 cとで構成し、 板ばね部材 7 2を後退させることによって可動刃 7 1 bと固定刃 7 1 cの間に位置する こととなる糸送出機構 2 8の糸送出管 2 8 aから導出された糸 1 1を、 所 定長さに切断するようにしている。  In this case, the cutter 71 is composed of a movable blade 71b driven by a rotary solenoid 71a and a fixed blade 71c, and the movable blade 71b is retracted to move the movable blade 71b. The thread 11 derived from the thread delivery tube 28 a of the thread delivery mechanism 28 located between the fixed blade 71 c and the fixed blade 71 c is cut to a predetermined length.
また、 このカッター 7 1には、 可動刃 7 1 bと略平行に糸押さえ片 7 1 dを配設し、 糸 1 1 を切断する際に、 ロータリーソレノイ ド 7 1 aによつ て糸押さえ片 7 1 dを可動刃 7 1 bと共に揺動させることによって、 糸押 さえ片 7 1 dによって可動刃 7 1 bに先だって糸 1 1を押し卞げるように し、 これにより、 糸 1 1の撚リ影響によって糸 1 1が跳ね上がることを防 止することができるようにしている。  The cutter 71 is provided with a thread retainer 71 d substantially in parallel with the movable blade 71 b so that when the thread 11 is cut, the thread is removed by a rotary solenoid 71 a. By swinging the holding piece 7 1d together with the movable blade 7 1b, the thread 1 1 is pressed by the thread holding piece 7 1d prior to the movable blade 7 1b so that the thread 1 1 It is possible to prevent the yarn 11 from jumping up due to the effect of twisting 1.
板ばね部材 7 2は、 2枚の板ばね 7 2 X、 7 2 Yを重ね合わせて構成し たもので、 一方の板ばね 7 2 Xは、 先端に第 1操作片 7 5に操作されるガ イ ド片 7 2 aを備え、 これによリ、 第 1操作片 7 5を 2枚の板ばね 7 2 X、 7 2 Y間に形成した開口部 7 2 f に円滑に導いた後、 この第 1操作片 7 5 と共に糸送出管 2 8 aから導出された糸 1 1が、 板ばね 7 2 X、 7 2 Y間 に形成した縦孔 7 2 c内に入り込むことができるようにする。 The leaf spring member 72 is formed by stacking two leaf springs 72X and 72Y, and one leaf spring 72X is operated by a first operation piece 75 at the tip. After the guide piece 72a is provided, the first operation piece 75 is smoothly guided to the opening 72f formed between the two leaf springs 72x and 72y. The thread 11 derived from the thread delivery pipe 28a together with the first operation piece 75 is moved between the leaf springs 7 2X and 7 2Y. So that it can penetrate the vertical hole 72c formed in the hole.
また、 一方の板ばね 7 2 Xは、 下端縁に切り欠き部 7 2 bを備えること により、 板ばね 7 2 X、 7 2 Y間に形成した縦孔 7 2 c内に入り込んだ第 1操作片 7 5が、 この切り欠き部 7 2 bから縦孔 7 2 c外に出ることがで きるようにし、 これにより、 糸送出管 2 8 aから導出された糸 1 1のみを、 縦孔 7 2 c内に残留させるようにする。  In addition, one leaf spring 72X has a cutout portion 72b at the lower end edge, so that the first operation that has entered the vertical hole 72c formed between the leaf springs 72X and 72Y. This allows the piece 75 to pass out of the vertical hole 72 c through the cutout 72 b so that only the yarn 11 derived from the yarn delivery pipe 28 a can be 2 Keep it in c.
さらに、 板ばね 7 2 X、 7 2 Yは、 後端に第 2操作片 7 6に操作される ガイ ド片 7 2 d、 7 2 βを備え、 これにより、 糸 1 1の排除時、 糸 1 1を 舉孔 7 2 cに揷通した状態で板ばね部材 7 2を後退させることで、 第 2操 作片 7 6によって開口部 7 2 f を押し開いて、 カッター 7 1により切断し た不要な糸を落下させることができるようにする。  Further, the leaf springs 7 2 X and 7 2 Y are provided at the rear end with guide pieces 7 2 d and 7 2 β operated by the second operation piece 76, so that when the thread 11 is removed, the thread is removed. By retracting the leaf spring member 7 2 with 1 1 passing through the hole 7 2 c, the opening 72 f was pushed open by the second operating piece 76 and cut by the cutter 71. Unnecessary thread can be dropped.
板ばね部材 7 2の前進及び後退動作は、 駆動機構 7 4により、 リンク機 構 7 3を介して行うようにする。  The forward and backward movements of the leaf spring member 72 are performed by the drive mechanism 74 via the link mechanism 73.
この場合、 駆動機構 7 4は、 第 1 3図に示すように、 駆動源としてのモ —タ 7 4 aにより駆動される回転軸 7 4 bの回転力を、 直流ソレノイ ド 7 4 c及びクラッチ盤 7 4 d、 7 4 eからなるクラッチ機構を介在すること により、 刺繍ロポッ卜のミシンへッ ド 1毎に独立して駆動可能に構成する ことができ、 これにより、 糸 1 1が切れたときの処理を含むすべての糸 1 に係る処理を自動で行うことができ、 ミシンの稼働率及び生産性を一層 向上することができるものとなる。  In this case, as shown in FIG. 13, the drive mechanism 74 transfers the torque of the rotating shaft 74 b driven by the motor 74 a as a drive source to the DC solenoid 74 c and the clutch. By interposing a clutch mechanism consisting of the boards 74d and 74e, it is possible to independently drive each sewing machine head 1 of the embroidery lopot, and the thread 11 is cut off. The processing relating to all the yarns 1 including the processing at the time can be automatically performed, and the operation rate and productivity of the sewing machine can be further improved.
なお、 糸の交換時等に切断した不要な糸を排除する糸切断■排除機構 7 は、 上記のものに限定されず、 例えば、 切断した不要な糸を排除する吸引 機構を備えた任意の構成のものを採用することができる。  In addition, the thread cutting / eliminating mechanism 7 for eliminating unnecessary thread cut when exchanging the thread is not limited to the above-described one.For example, any configuration including a suction mechanism for eliminating the cut unnecessary thread is used. Can be adopted.
また、 糸切断 '排除機構 7に代えて、 針 1 0に向けて送り出された糸 1 1を回収、 保持する糸長さ調節機構 (図示省略) を配設することにより、 廃棄する糸 1 1の無駄をなくするようにすることもできる。 In addition, instead of the thread cutting and removing mechanism 7, a thread length adjusting mechanism (not shown) for collecting and holding the thread 11 sent out toward the needle 10 is provided. It is also possible to eliminate waste of the thread 11 to be discarded.
さらに、 本実施例のものにおいては、 天秤機構 4を、 天秤 4 1 と、 副天 秤 4 2と、 ブレーキモータ又はエアーモータからなる副天秤 4 2の駆動機 構 4 3とで構成するとともに、 副天秤 4 2を、 上死点の位置 4 2 Xから、 2段階、 すなわち、 下死点の位置 4 2 Y及び定位置 4 2 Zに揺動可能なよ うに、 各位置にストツバ 4 2 x、 4 2 y、 4 2 zを配設し、 糸張力調節機 構 2 5に吸収される糸長さを確保するようにしている。  Further, in the present embodiment, the balance mechanism 4 includes a balance 41, a sub balance 42, and a driving mechanism 43 of the sub balance 42 including a brake motor or an air motor. The sub balance 42 is moved from the top dead center position 4 2 X to two positions, namely, the bottom dead center position 4 2 Y and the home position 4 2 Z so that it can be swung to each position 4 2 x. , 42 y, and 42 z are provided to secure the yarn length absorbed by the yarn tension adjusting mechanism 25.
この場合、 定位置 4 2 Zを規定するストツパ 4 2 Zは、 直流ソレノイ ド 等の駆動機構を備え、 これにより、 ストッパ 4 2 Zを没することにより、 副天秤 4 2をストツバ 4 2 zの位置を一旦通過させた後、 ストツバ 4 2 Z を突出することにより、 副天秤 4 2をストツバ 4 2 zに当接させ、 正確に 刺繍を行う定位置 4 2 Zに位置させることができるようにしている。 In this case, a stop 4 2 Z defining the position 4 2 Z is provided with a drive mechanism such as a DC solenoids, Thus, by submerged the stopper 4 2 Z, the secondary balance 4 2 Sutotsuba 4 2 z After passing through the position once, the sub-balance 4 2 Z is projected to make the sub balance 4 2 abut against the storage band 4 2 z, so that it can be positioned at the fixed position 4 2 Z where accurate embroidery is performed. ing.
また、 副天秤 4 2の駆動機構 4 3は、 本実施例においては、 各ミシンへ ッド毎に独立した駆動源を配設するようにしているが、 共通の駆動源の場 合には、 各ミシンへッ ドとの間にクラッチを介在するようにする。  In the present embodiment, the drive mechanism 43 of the sub balance 42 is provided with an independent drive source for each sewing machine head. However, in the case of a common drive source, A clutch should be interposed between each machine head.
上記のように構成することにより、 糸 1 1を張設する際に、 糸張力調節 機構 2 5の糸 1 1にテンションをかけるばね機構等によって吸収される糸 長さを確保し、 糸通しを行うときに糸長さが不足することを確実に防止す ることができるようにしている。  With the above configuration, when the thread 11 is stretched, the thread length is absorbed by a spring mechanism that applies tension to the thread 11 of the thread tension adjustment mechanism 25, and the thread is passed through. It is ensured that shortage of the yarn length can be prevented when performing.
なお、 ミシンヘッ ド 1にポビン収容部ユニッ ト 2 2 A、 2 2 Bを着脱自 在に取リ付けるようにする場合には、 ボビン収容部ユニッ ト 2 2 A、 2 2 Bを、 望ましくは、 ミシンヘッ ド 1の頭数の複数倍個用意しておく。 これ により、 色糸の交換を行う場合には、 ポビン収容部ュニッ ト 2 2 A、 2 2 Bごと交換して色糸の交換に要する時間を短縮することができる。 例えば、 本実施例のポビン収容部ユニッ ト 2 2 A、 2 2 Bをミシンヘッドの頭数の 2倍の個数用意しておけば、 最大 4 0色の色糸の交換を短時間で行うこと ができる。 この場合、 刺繍口ポッ トの制御部にポビン収容部 2 2に収容さ れた各ポビン 2 1の種類 (色) を予め記憶させておくことにより、 ポビン 収容部ユニット 2 2 A、 2 2 Bを交換するだけで、 多数の色糸の交換を簡 易に行うことができる。 If the pobin housing units 22A and 22B are to be attached and detached to the sewing machine head 1, the bobbin housing units 22A and 22B should be attached to Prepare several times the number of heads of sewing head 1. Thus, when the color yarn is replaced, the time required for the replacement of the color yarn can be reduced by replacing the pobin housing units 22A and 22B together. For example, the pobin housing units 22A and 22B of this embodiment are By preparing twice the number, it is possible to exchange color threads of up to 40 colors in a short time. In this case, by storing in advance the type (color) of each pobin 21 stored in the pobin housing section 22 in the control section of the embroidery port, the pobin housing section units 22A and 22B can be stored. It is possible to easily exchange a large number of colored yarns simply by replacing the yarn.
また、 本実施例においては、 所要のボビン 2 1に対応する糸送出機構 2 8の糸送出管 2 8 aを所定の針 1 0に糸通しを行う糸通し装置 5の上方に 選択的に位置させるため、 糸選択機構 2 9により糸調節機構 2 4を摺動さ せるようにしているが、 糸選択機構として、 糸調節機構 2 4を支軸を揺動 軸として揺動駆動する機構を採用することもできる。  In the present embodiment, the thread delivery tube 28 a of the thread delivery mechanism 28 corresponding to the required bobbin 21 is selectively positioned above the threading device 5 for threading a predetermined needle 10. The thread adjusting mechanism 24 is slid by the thread selecting mechanism 29 in order to ensure that the thread adjusting mechanism 24 is slid with the thread adjusting mechanism 24 as a pivot. You can also.
また、 糸調節機構 2 4の本体 2 4 aの近傍のミシンへッド 1には、 第 1 7図に示すように、 2個の糸張力調節部材 2 5 a、 2 5 bにより加えられ る糸 1 1の張力の大きさを調整するための糸張力調節具 2 5 cを配設する ようにする。  Further, as shown in FIG. 17, two thread tension adjusting members 25a and 25b are applied to the sewing machine head 1 near the main body 24a of the thread adjusting mechanism 24. A thread tension adjuster 25c for adjusting the tension of the thread 11 should be provided.
この糸張力調節具 2 5 cは、 後述の糸供給装置 2より下方に位置する天 秤 4 1及び副天秤 4 2からなる天秤機構 4、 針 1 0等を介して糸 1 1にか かる張力と同等の張力を糸 1 1にかけることができるもので、 これにより、 糸 1 1を天秤 4 1、 副天秤 4 2、 針 1 0等に掛け渡すことなく、 2個の糸 張力調節部材 2 5 a、 2 5 bによリ加えられる各ポビン 2 1からの糸 1 1 の張力の大きさを均一に調整することができるようにする。 そして、 この 糸張力調節具 2 5 cは、 基部に磁石を配設して、 ミシンへッド 1の適宜位 置、 より具体的には、 針 1 0に向けて各ボビン 2 1からの糸 1 1 を送り出 すために設けられる糸送出機構 2 8の糸送出管 2 8 aの下方位置に選択的 に着脱可能に設置することができるようにする。  The thread tension adjuster 25c is used to adjust the tension applied to the thread 11 via a balance mechanism 4 including a balance 41 and an auxiliary balance 42 located below a thread supply device 2 described later, a needle 10 and the like. The same tension can be applied to the thread 1 1, and this allows the two thread tension adjusting members 2 without hanging the thread 11 on the balance 4 1, sub balance 4 2, needle 10, etc. The magnitude of the tension of the thread 11 from each of the pobins 21 added by 5a and 25b can be uniformly adjusted. The thread tension adjuster 25 c is provided with a magnet at the base to appropriately position the sewing machine head 1, more specifically, the thread from each bobbin 21 toward the needle 10. 11. A thread delivery mechanism provided to deliver 1 1 and 28 can be selectively detachably installed below the thread delivery pipe 28 a of the thread delivery tube 28 a.
ミシンヘッ ド 1の糸供給装置 2の下部には、 本件発明者が先に提案した ( P C T Z J P 9 7ノ0 2 6 0 1、 P C T / J P 9 7 0 2 6 0 2、 P C T / J P 0 1 / 0 1 7 6 3参照) ような糸張設機構 3及び糸通し機構 6か らなる糸通し装置 5並びに針棒支持機構 8を配設する。 In the lower part of the thread supply device 2 of the sewing head 1, the inventor of the present invention has proposed (See PCTZJP 9 7 0 2 0 6 0 1, PCT / JP 9 0 7 2 0 2, PCT / JP 0 1/0 1 7 6 3) Threading mechanism 3 and threading mechanism 6 A threading device 5 and a needle bar support mechanism 8 are provided.
この糸通し装置 5は、 糸供給装置 2の糸送出管 2 8 aから所定長さ垂下 された糸 1 1の端部を針 1 0の近傍位置まで導くとともに、 糸 1 1を天秤 機構 4の天秤 4 1及び副天秤 4 2に掛け渡し、 さらに、 針 1 0の近傍位置 まで導かれた糸 1 1を針 1 0の針孔 1 0 aに糸通しするものである。  The threading device 5 guides the end of the thread 11 suspended by a predetermined length from the thread delivery pipe 28 a of the thread supply device 2 to a position near the needle 10, and transfers the thread 11 to the balance mechanism 4. The thread 11 is passed over the balance 41 and the auxiliary balance 42, and the thread 11 guided to a position near the needle 10 is threaded through the needle hole 10a of the needle 10.
また、 針棒支持機構 8は、 糸通し機構 6の糸引き抜き機構の先端を鉤形 に形成したフック部材 6 1を針 1 0の針孔に揷通する際に、 針棒のぶれを 修正し、 針棒を所定位置に位置決めするものである。  Further, the needle bar support mechanism 8 corrects the deflection of the needle bar when passing the hook member 61 having the hook-shaped tip of the thread pull-out mechanism of the threading mechanism 6 through the needle hole of the needle 10. The needle bar is positioned at a predetermined position.
次に、 本実施例の刺繍ロボッ 卜の操作方法について説明する。  Next, a method of operating the embroidery robot of this embodiment will be described.
まず、 刺繍の前段階の操作方法について説明する。  First, a description will be given of an operation method at a stage prior to embroidery.
刺繍を開始するときには、 刺繍ロポッ 卜のミシンへッ ド 1の糸供給装置 2のポビン収容部 2 2に、 各々色糸のポビン 2 1 を収容し、 ボビン 2 1か ら繰り出した糸 1 1を糸保持体 2 3を介して、 糸調節機構 2 4を構成する、 糸張力調節機構 2 5、 糸長さ調節機構 2 6及び糸送出機構 2 8に掛け渡し、 糸 1 1の端部を糸送出機構 2 8の糸送出管 2 8 aから所定長さ垂下するよ うにする。  At the start of embroidery, each color thread pobin 21 is stored in the pobin storage section 22 of the thread supply device 2 of the sewing machine head 1 of the embroidery lopot, and the thread 11 fed from the bobbin 21 is fed. The thread adjusting mechanism 24 is formed via the thread holder 23, the thread tension adjusting mechanism 25, the thread length adjusting mechanism 26, and the thread sending mechanism 28, and the end of the thread 11 is threaded. The thread is suspended from the thread delivery tube 28 a of the delivery mechanism 28 by a predetermined length.
次に、 本実施例の刺繍ロボッ 卜について、 刺繍を開始するときの操作方 法について、 第 6図〜第 9図に基づいて説明する。  Next, the embroidery robot according to the present embodiment will be described with reference to FIGS.
糸供給装置 2の糸選択機構 2 9を駆動することにより、 糸調節機構 2 4 を摺動させ、 所要のボビン 2 1に対応する糸送出機構 2 8の糸送出管 2 8 aを糸通しを行う糸通し装置 5の上方に選択的に、 かつ、 正確に位置させ る。  By driving the thread selection mechanism 29 of the thread supply device 2, the thread adjustment mechanism 24 is slid, and the thread delivery pipe 28a of the thread delivery mechanism 28 corresponding to the required bobbin 21 is passed through the threader. It is selectively and accurately positioned above the threading device 5 to be used.
この時、 合わせて、 糸通し機構 6及び針棒支持機構 8の駆動機構を駆動 することにより、 針 1 0に糸 1 1を揷通する準備をするようにする。 At this time, the drive mechanisms of the threading mechanism 6 and the needle bar support mechanism 8 are also driven. By doing so, be prepared to pass the thread 11 through the needle 10.
その後、 糸仮保持機構 2 6により糸 1 1 を仮保持することにより、 糸 1 1が送り出されることを防止する。  Thereafter, the yarn 11 is temporarily held by the yarn temporary holding mechanism 26 to prevent the yarn 11 from being sent out.
この状態で、 待機位置にある糸払い '保持機構 2 8 bの駆動機構 2 8 g (第 8図①) を駆動することによって、 糸送出管 2 8 aを板ばね部材 2 8 e、 2 8 f 間に形成した開口部 2 8 cに向けて導くようにし (第 8図②) 、 さらに、 糸払い■保持機構 2 8 bの駆動機構 2 8 gを駆動することによつ て、 糸送出管 2 8 aを板ばね部材 2 8 e、 2 8 f 間に形成した開口部 2 8 cに向けて導き (第 8図②) 、 糸送出管 2 8 aを縦孔 2 8 d内に入り込む ようにした後、 縦孔 2 8 d外に出るようにして (第 8図③) 、 糸送出管 2 8 aから導出された糸 1 1のみが、 縦孔 2 8 d内に残留されるようにする (第 9図④) 。  In this state, by driving the drive mechanism 28 g (FIG. 8①) of the thread wiper holding mechanism 28 b at the standby position, the thread delivery pipe 28 a is connected to the leaf spring members 28 e and 28. The thread is guided toward the opening 28c formed between the f and the thread feeder by driving the drive mechanism 28g of the thread wiper / holding mechanism 28b (FIG. 8②). The pipe 28a is guided toward the opening 28c formed between the leaf spring members 28e and 28f (Fig. 8 (1)), and the thread delivery pipe 28a enters the vertical hole 28d. After that, make it go out of the vertical hole 28 d (Fig. 8 (3)) so that only the yarn 11 derived from the yarn delivery pipe 28 a remains in the vertical hole 28 d. (Fig. 9 ②).
そして、 糸張設機構 3の駆動機構 3 2を駆動することによって、 糸張設 機構 3の糸挟持部材 3 1を略中間部 (天秤機構 4の副天秤 4 2の定位置 4 2 Z近傍) の待機位置 (第 6図①) から、 糸送出機構 2 8の糸送出管 2 8 aから垂下された糸 1 1の端部を挟持する最上昇位置 (糸送出管 2 8 aの 下端より上方位置) まで移動させる (第 6図②) 。  Then, by driving the drive mechanism 32 of the thread tensioning mechanism 3, the thread clamping member 31 of the thread tensioning mechanism 3 is substantially in the middle (near the fixed position 4 2 Z of the sub-balance 4 2 of the balance mechanism 4). From the standby position (Fig. 6 (1)) to the highest position where the end of the thread 11 hanging from the thread delivery pipe 28a of the thread delivery mechanism 28 is clamped (above the lower end of the thread delivery pipe 28a). Position) (Fig. 6, ①).
その後、 駆動機構 2 8 gを逆方向に駆動することによって、 糸送出管 2 8 aから導出された糸 1 1を、 横方向に払って糸払い ·保持機構 2 8 bの 縦孔 2 8 d内に揷通した状態で、 糸払い■保持機構 2 8 bによって確実に 仮保持するようにする (第 9図⑤) 。  Then, by driving the drive mechanism 28 g in the reverse direction, the thread 11 drawn out from the thread delivery pipe 28 a is swept in the horizontal direction, and the vertical hole 28 d of the thread wiping and holding mechanism 28 b is formed. While threading through the inside, be sure to temporarily hold it with the thread wiper holding mechanism 28b (Fig. 9 ①).
なお、 駆動機構 2 8 gを逆方向に駆動すると、 糸払い■保持機構 2 8 b の板ばね部材 2 8 f ( 2 8 e ) が糸送出管 2 8 aの先端部に接触すること になるが、 このとき、 板ばね部材 2 8 f ( 2 8 e ) が撓むことによって、 糸送出管 2 8 aの位置を通過することができる。 そして、 糸送出管 2 8 aから導出された糸 1 1を、 横方向に払って仮保 持した状態で、 糸張設機構 3の糸挟持部材 3 1の可動挟持片 3 1 aと固定 挟持片 3 1 bを降下させるとともに閉じて、 糸 1 1を挟持するようにするWhen the drive mechanism 28 g is driven in the reverse direction, the leaf spring member 28 f (28 e) of the thread wiper holding mechanism 28 b comes into contact with the tip of the thread delivery pipe 28 a. However, at this time, the leaf spring member 28 f (28 e) bends, so that it can pass through the position of the yarn delivery pipe 28 a. Then, the thread 11 drawn out from the thread delivery pipe 28 a is swept in the horizontal direction and temporarily held, and is fixed to the movable holding piece 3 1 a of the thread holding member 3 1 of the thread tensioning mechanism 3. Lower the piece 3 1 b and close it so that the thread 1 1 is clamped
(第 6図③) 。 (Fig. 6, ③).
このとき、 糸送出管 2 8 aから導出された糸 1 1は、 横方向に払って仮 保持した状態にあるため、 糸 1 1を、 糸張設機構 3の糸挟持部材 3 1の可 動挟持片 3 1 aと固定挟持片 3 1 bの間で、 所定精度の挟持状態の下に正 確に挟持することができる。  At this time, since the thread 11 drawn out from the thread delivery pipe 28 a is in a state of being temporarily held by being paid in the lateral direction, the thread 11 is moved by the thread holding member 3 1 of the thread tensioning mechanism 3. The holding piece 31a and the fixed holding piece 31b can be accurately held under a holding state of a predetermined accuracy.
この状態で、 糸仮保持機構 2 6による糸 1 1の仮保持を一旦解除し、 こ れにより、 ボビン収容部 2 2に収容したポビン 2 1から糸 1 1が自由に繰 リ出されるようにして、 糸張設機構 3の糸挟持部材 3 1を、 略中間部 (天 秤機構 4の副天秤 4 2の定位置 4 2 Z近傍) の待機位置まで降下させる (第 6図④) 。  In this state, the temporary holding of the yarn 11 by the temporary yarn holding mechanism 26 is temporarily released, so that the yarn 11 can be freely fed out of the pobin 21 stored in the bobbin housing 22. Then, the thread holding member 31 of the thread tensioning mechanism 3 is lowered to a standby position substantially in the middle (near the fixed position 42Z of the sub-balance 42 of the balance mechanism 4) (Fig. 6 (1)).
次に、 糸仮保持機構 2 6による糸 1 1の仮保持を解除したまま、 糸供給 装置 2の糸選択機構 2 9を駆動することにより、 糸張設機構 3の糸挟持部 材 3 1 との間で糸 1 1が掛け渡された状態の糸送出管 2 8 aを 1段階側方 (右側) に移動させる (第 6図⑤) 。  Next, while the temporary holding of the yarn 11 by the temporary yarn holding mechanism 26 is released, the yarn selection mechanism 29 of the yarn supply device 2 is driven to thereby hold the yarn holding member 3 1 of the yarn tensioning mechanism 3 together. The yarn delivery tube 28a with the yarn 11 stretched between them is moved to the side (right side) by one step (Fig. 6, ①).
そして、 糸仮保持機構 2 6による糸 1 1の仮保持を解除したまま、 ポビ ン収容部 2 2に収容したボビン 2 1から糸 1 1が自由に繰り出されるよう にして、 ブレーキモータ又はエア一モータからなる副天秤 4 2の駆動機構 4 3を駆動することによって、 副天秤 4 2を上死点の位置 4 2 Xから下死 点の位置 4 2 Yまで一旦移動させる。 その後、 定位置 4 2 Zに移動させる ことにより、 糸 1 1 を天秤 4 1及び副天秤 4 2に掛け渡すようにしながら、 糸張力調節機構 2 5の糸 1 1にテンションをかけるばね機構や後述の糸挟 持部材 3 1 と糸張架機構 3 3との間に張架することによって吸収される糸 長さを確保し、 糸通しを行うときに糸長さが不足することを防止するよう にする。 そして、 さらに、 糸張設機構 3の駆動機構 3 2を駆動することに よって、 糸張設機構 3の糸挟持部材 3 1 を降下させる (第 6図⑥) 。 Then, while the temporary holding of the yarn 11 by the yarn temporary holding mechanism 26 is released, the yarn 11 is unwound from the bobbin 21 accommodated in the pobin accommodating portion 22 so as to be freely fed out, and the brake motor or the air is released. By driving the driving mechanism 43 of the sub balance 42 composed of one motor, the sub balance 42 is temporarily moved from the position 42 X of the top dead center to the position 42 Y of the bottom dead center. After that, by moving the thread 11 to the balance 41 and the sub-balance 42 by moving the thread 11 to the fixed position 4 2 Z, a spring mechanism for applying tension to the thread 11 of the thread tension adjusting mechanism 25 and a later-described mechanism. Yarn that is absorbed by being stretched between the yarn clamping member 3 1 and the yarn tensioning mechanism 3 3 Secure the length and prevent shortage of the thread length when performing threading. Then, by further driving the drive mechanism 32 of the thread tensioning mechanism 3, the thread holding member 31 of the thread tensioning mechanism 3 is lowered (FIG. 6⑥).
この場合、 副天秤 4 2の定位置 4 2 Zを規定するストツバ 4 2 Zは、 直 流ソレノイ ド等の駆動機構を備え、 これにより、 ストツバ 4 2 zを没する ことによリ、 副天秤 4 2をストッパ 4 2 zの位置を一旦通過させた後、 ス トツパ 4 2 zを突出することにより、 副天秤 4 2をストッパ 4 2 zに当接 させ、 正確に刺繍を行う定位置 4 2 Zに位置させることができるようにし ている。 In this case, Sutotsuba 4 2 Z defining the position 4 2 Z sub balance 4 2 is provided with a drive mechanism such as a straight-flow solenoids, thereby, in particular good re submerged the Sutotsuba 4 2 z, sub balance After passing through the position of the stopper 4 2 z once, the stopper 4 2 z is protruded to bring the sub-balance 4 2 into contact with the stopper 4 2 z, so that the embroidery can be performed accurately. It can be positioned at Z.
また、 糸挟持部材 3 1に挟持された糸 1 1を、 糸挟持部材 3 1 と糸張架 機構 3 3との間に張架することにより、 張架した糸 1 1を、 前もって針 1 0の針孔 1 0 aに揷通された糸通し機構 6のフック部材 6 1上に載置する ようにする。  Further, the thread 11 held between the thread holding members 3 1 is stretched between the thread holding member 3 1 and the thread tensioning mechanism 33, so that the stretched thread 11 is moved in advance by the needle 10. On the hook member 61 of the threading mechanism 6 passed through the needle hole 10a.
なお、 副天秤 4 2及び糸挟持部材 3 1の移動の開始順序は、 糸 1 1が天 秤 4 1及び副天秤 4 2に確実に掛け渡されるように、 適宜時間差を持たせ るようにする。  The starting order of the movement of the sub-balance 42 and the thread holding member 31 is such that there is an appropriate time difference so that the thread 11 can be reliably passed over the balance 41 and the sub-balance 42. .
この状態で、 針棒支持機構 8の駆動機構を駆動することにより、 針棒の 支持を解除し、 糸通し機構 6の駆動機構を駆動することにより、 糸通し機 構 6のフック部材 6 1を針 1 0の針孔 1 0 aから引き抜くようにして、 針 1 0の針孔 1 0 aに糸 1 1を揷通するとともに、 糸挟持部材 3 1の可動挟 持片 3 1 aと固定挟持片 3 1 bを開いて糸 1 1の挟持を解除するようにす る (第 6図⑦) 。  In this state, the drive mechanism of the needle bar support mechanism 8 is driven to release the support of the needle bar, and the drive mechanism of the threading mechanism 6 is driven to release the hook member 61 of the threading mechanism 6. Pull the thread 11 through the needle hole 10 a of the needle 10 by pulling it out from the needle hole 10 a of the needle 10, and fix and clamp the movable clamping piece 3 1 a of the thread clamping member 3 1 Open the piece 3 1 b to release the pinching of the thread 11 (Fig. 6, ①).
その後、 糸張設機構 3の駆動機構 3 2を駆動することによって、 糸張設 機構 3の糸挟持部材 3 1を略中間部 (天秤機構 4の副天秤 4 2の定位置 4 2 Z近傍) の待機位置まで上昇させながら、 糸張架機構 3 3を復帰させ、 待機させるようにする (第 6図⑧) 。 Then, by driving the driving mechanism 32 of the thread tensioning mechanism 3, the thread clamping member 31 of the thread tensioning mechanism 3 is moved to the substantially intermediate portion (near the fixed position 4 2 Z of the sub balance 4 2 of the balance mechanism 4). , While returning to the standby position Make it stand by (Fig. 6 ①).
なお、 糸張設機構 3の糸挟持部材 3 1を降下中の適宜段階で、 第 1 5図 ( A ) 〜 (D ) に示すように、 糸切断 '排除機構 7の駆動機構 7 4を駆動 することにより、 板ばね部材 7 2を前進させ、 第 1操作片 7 5によって板 ばね部材 7 2の開口部 7 2 f を押し開いて糸送出管 2 8 aから導出された 糸 1 1 を縦孔 7 2 cに揷通しておくようにする。  At an appropriate stage during the lowering of the thread holding member 31 of the thread tensioning mechanism 3, the drive mechanism 74 of the thread cutting / removing mechanism 7 is driven as shown in FIGS. 15 (A) to 15 (D). Then, the leaf spring member 72 is moved forward, and the opening 72 f of the leaf spring member 72 is pushed open by the first operation piece 75 so that the thread 111 drawn out from the thread delivery pipe 28 a is vertically moved. Make sure it passes through hole 7 2 c.
そして、 刺繍を開始するようにする。 なお、 これは、 自動的に行うこと ができる。  Then, start embroidery. Note that this can be done automatically.
一方、 上記のようにして糸通しを行う際に、 針 1 0に前に刺繍を行った 糸 1 1が揷通されている場合 (色糸 1 1の交換作業を行う場合) には、 糸 仮保持機構 2 6により糸 1 1 を仮保持することにより、 糸 1 1 (新旧両方 の糸) が送り出されることを防止した状態で、 第 6図①〜④の適宜段階で、 糸 1 1を針板 (図示省略) の下方に配設した自動糸切り装置により切断す るとともに、 第 1 5図 (き) に示すように、 糸切断■排除機構 7の駆動機 構 7 4を駆動することにより、 糸 1 1を縦孔 7 2 cに揷通した状態で板ば ね部材 7 2を後退させ、 カッター 7 1により糸送出機構 2 8の糸送出管 2 8 aから導出された糸 1 1を所定長さに切断するとともに、 第 2操作片 7 6によって開口部 7 2 f を押し開いて切断した不要な糸を落下させるよう にする。  On the other hand, when performing threading as described above, if the previously embroidered thread 11 is passed through the needle 10 (when replacing the colored thread 11), the thread By temporarily holding the yarn 11 by the temporary holding mechanism 26, the yarn 11 (both new and old yarns) is prevented from being sent out. The cutting is performed by an automatic thread trimmer arranged below the needle plate (not shown), and the drive mechanism 74 of the thread trimmer 7 is driven as shown in Fig. 15 (g). The plate spring member 7 2 is retracted while the thread 11 passes through the vertical hole 7 2 c, and the thread 1 1 drawn out from the thread delivery pipe 28 a of the thread delivery mechanism 28 by the cutter 7 1 Is cut to a predetermined length, and the opening 72 f is pushed open by the second operation piece 76 so that the cut unnecessary thread is dropped.
以下、 糸供給装置 2の糸選択機構 2 9を駆動することにより、 糸送出機 構 2 8の糸送出管 2 8 aを 1段階ずつ側方 (右側) に移動させながら、 複 数の糸 (複数種類の色糸) 1 1を用いて、 ポビン収容部 2 2に収容された ボビン (色糸) 2 1の順に、 刺繍を行うようにする。  Hereinafter, by driving the yarn selection mechanism 29 of the yarn supply device 2, the yarn delivery pipe 28a of the yarn delivery mechanism 28 is moved side by side (to the right) one step at a time, and a plurality of yarns ( Embroidery is performed in the order of bobbins (color threads) 21 stored in the pobin storage section 22 using a plurality of types of color threads 1 1.
そして、 刺繍が完了し、 次の対象物品に対して刺繍を行う場合には、 糸 1 1 を針板 (図示省略) の下方に配設した自動糸切り装置により切断する とともに、 糸切断 '排除機構 7によって切断、 排除した後、 糸供給装置 2 の糸選択機構 2 9を駆動することによリ糸調節機構 2 4を摺動させ、 所要 のボビン 2 1に対応する糸送出機構 2 8の糸送出管 2 8 aを糸通しを行う 糸通し装置 5の上方に選択的に、 かつ、 正確に位置させるようにして、 糸 張設機構 3、 糸通し装置 5等により、 糸 1 1を張設するとともに、 針 1 0 に糸通しを行って、 刺繍を行うようにする。 Then, when the embroidery is completed and the next target article is to be embroidered, the thread 11 is cut by an automatic thread cutting device arranged below a needle plate (not shown). At the same time, after the yarn is cut and eliminated by the yarn cutting / eliminating mechanism 7, the yarn adjusting mechanism 24 of the yarn supplying device 2 is driven to slide the yarn adjusting mechanism 24 to correspond to the required bobbin 21. The thread delivery tube 28 a of the thread delivery mechanism 28 is threaded. The thread tensioning mechanism 3, the threading device 5, etc. are used to selectively and accurately position the thread delivery device 5 above the threading device 5. The thread 11 is stretched, and the needle 10 is threaded to perform embroidery.
また、 ボビン収容部 2 2に収容されたポビン (色糸) 2 1のうち、 任意 のポビン (色糸) を選択する場合にも、 同様にして、 糸 1 1を切断、 排除 した後、 新たな糸 1 1 を張設するとともに、 針 1 0に糸通しを行って、 刺 繍を行うようにする。 これにより、 ポビン収容部 2 2に収容されたボビン (色糸) 2 1のうち、 任意のポビン (色糸) を選択して、 刺繍を行うこと ができる。  Similarly, when an arbitrary pobin (color thread) is selected from the pobins (color threads) 21 stored in the bobbin storage section 22, the thread 11 is cut and removed in the same manner, and then a new one is selected. Embroidery is performed by stretching the thread 11 and threading the needle 10. Thereby, any of the bobbins (color threads) 21 among the bobbins (color threads) 21 stored in the pobin storage section 22 can be selected and embroidered.
次に、 刺繍を行っている途中で糸 1 1が切れた場合の処理方法について 説明する。  Next, a processing method when the thread 11 is broken during embroidery will be described.
本実施例においては、 少なくとも、 糸仮保持機構 2 6、 糸払い■保持機 構 2 8 b、 副夫秤 4 2、 副天秤 4 2のストッパ 4 2 z及び糸切断■排除機 構 7の駆動機構を、 刺繍ロボッ 卜のミシンへッド 1毎に独立して駆動可能 に構成するようにしているため、 糸 1 1が切れた場合の処理を自動で行う ことができる。  In the present embodiment, at least the driving of the thread temporary holding mechanism 26, the thread wiping and holding mechanism 28 b, the sub-balance 4, the stopper 4 2 z of the auxiliary balance 42 and the thread cutting and removing mechanism 7 Since the mechanism is configured so that it can be driven independently for each sewing head 1 of the embroidery robot, it is possible to automatically perform processing when the thread 11 is broken.
刺繍を行っている途中で糸 1 1が切れた場合、 刺繍口ポットのミシンへ ッ ド 1のすベてを停止する。  If the thread 11 breaks during embroidery, stop all the sewing head 1 in the embroidery pot.
次に、 糸 1 1が切れたミシンへッ ド 1のみ、 糸仮保持機構 2 6により糸 1 1 を仮保持することにより、 糸 1 1 (新旧両方の糸) が送り出されるこ とを防止した状態で、 糸 1 1 を針板 (図示省略) の下方に配設した自動糸 切り装置により切断するとともに、 第 1 5図 (E ) に示すように、 糸切断 ■排除機構 7の駆動機構 7 4を駆動することにより、 糸 1 1を縦孔 7 2 c に揷通した状態で板ばね部材 7 2を後退させ、 カッター 7 1によ y糸送出 機構 2 8の糸送出管 2 8 aから導出された糸 1 1を所定長さに切断すると ともに、 第 2操作片 7 6によって開口部 7 2 f を押し開いて切断した不要 な糸を落下させるようにする。 Next, only the sewing machine head 1 with the broken thread 11 is temporarily held by the thread temporary holding mechanism 26 to prevent the thread 11 (both old and new threads) from being sent out. In this state, the thread 11 is cut by the automatic thread cutter installed below the needle plate (not shown), and the thread is cut as shown in Fig. 15 (E). ■ By driving the drive mechanism 74 of the elimination mechanism 7, the leaf spring member 72 is retracted with the thread 11 passing through the vertical hole 72c, and the thread feed mechanism 28 is driven by the cutter 71. The yarn 11 drawn out from the yarn sending pipe 28a of the above is cut to a predetermined length, and the opening 72f is pushed open by the second operation piece 76 to drop the unnecessary yarn cut. .
次に、 糸送出管 2 8 aを 1段階側方 (左側) に移動させる。  Next, the yarn delivery pipe 28a is moved to the side by one step (left side).
この時、 合わせて、 副天秤 4 2、 糸通し機構 6及び針棒支持機構 8の駆 動機構を駆動することにより、 針 1 0に糸 1 1 を揷通する準備をするよう にする。  At this time, the auxiliary balance 42, the threading mechanism 6, and the driving mechanism of the needle bar support mechanism 8 are driven to prepare for passing the thread 11 through the needle 10.
この場合、 副天秤 4 2の定位置 4 2 Zを規定するストツバ 4 2 zを没す ることにより、 副天秤 4 2を上死点の位置 4 2 Xまで上昇させるようにす る。  In this case, the sub balance 42 is moved up to the position 42 X of the top dead center by immersing the stopper 42 z defining the fixed position 42 Z of the sub balance 42.
その後、 糸仮保持機構 2 6により糸 1 1を仮保持したままで、 待機位置 にある糸払い '保持機構 2 8 bの駆動機構 2 8 g (第 8図①) を駆動する ことによって、 糸送出管 2 8 aを板ばね部材 2 8 e、 2 8 f 間に形成した 開口部 2 8 cに向けて導くようにし (第 8図②) 、 さらに、 糸払い -保持 機構 2 8 bの駆動機構 2 8 gを駆動することによって、 糸送出管 2 8 aを 板ばね部材 2 8 e、 2 8 f 間に形成した開口部 2 8 cに向けて導き (第 8 図②) 、 糸送出管 2 8 aを縦孔 2 8 d内に入り込むようにした後、 縦孔 2 8 d外に出るようにして (索8図③) 、 糸送出管 2 8 aから導出された糸 1 1のみが、 縦孔 2 8 d内に残留されるようにする (第 9図④) 。  After that, while the yarn 11 is temporarily held by the yarn temporary holding mechanism 26, the drive mechanism 28g (Fig. 8①) of the yarn sweeper's holding mechanism 28b at the standby position is driven, whereby the yarn is removed. The delivery pipe 28a is guided toward the opening 28c formed between the leaf spring members 28e and 28f (Fig. 8 (1)), and furthermore, the thread wiper-holding mechanism 28b is driven. By driving the mechanism 28 g, the thread delivery tube 28 a is guided toward the opening 28 c formed between the leaf spring members 28 e and 28 f (FIG. 8②). After inserting 28a into the vertical hole 28d, it is made to go out of the vertical hole 28d (Cable 8 Fig. ③), and only the yarn 11 derived from the yarn delivery pipe 28a is However, it should be left in the vertical hole 28d (Fig. 9 ①).
そして、 糸張設機構 3の駆動機構 3 2を駆動することによって、 糸張設 機構 3の糸挟持部材 3 1を略中間部 (天秤機構 4の副天秤 4 2の定位置 4 2 Z近傍) の待機位置 (第 6図①) から、 糸送出機構 2 8の糸送出管 2 8 aから垂下された糸 1 1の端部を挾持する最上昇位置 (糸送出管 2 8 aの 下端より上方位置) まで移動させる (第 6図②) 。 Then, by driving the drive mechanism 32 of the thread tensioning mechanism 3, the thread clamping member 31 of the thread tensioning mechanism 3 is substantially in the middle (near the fixed position 4 2 Z of the sub-balance 4 2 of the balance mechanism 4). From the standby position (Fig. 6 (1)), the highest position where the end of the thread 11 hanging from the thread delivery pipe 28a of the thread delivery mechanism 28 is held (the thread delivery pipe 28a (Figure 6).
その後、 駆動機構 2 8 gを逆方向に駆動することによって、 糸送出管 2 8 aから導出された糸 1 1を、 横方向に払って糸払い■保持機構 2 8 の 縦孔 2 8 d内に揷逋した状態で、 糸払い■保持機構 2 8 bによって確実に 仮保持するようにする (第 9図⑤) 。  Then, by driving the drive mechanism 28 g in the reverse direction, the yarn 11 derived from the yarn delivery pipe 28 a is swept in the horizontal direction, and the inside of the vertical hole 28 d of the Make sure to temporarily hold the thread with the thread wiper holding mechanism 28b (Fig. 9 (1)).
なお、 駆動機構 2 8 gを逆方向に駆動すると、 糸払い■保持機構 2 8 b の板ばね部材 2 8 f ( 2 8 e ) が糸送出管 2 8 aの先端部に接触すること になるが、 このとき、 板ばね部材 2 8 f ( 2 8 e ) が撓むことによって、 糸送出管 2 8 aの位置を通過することができる。  When the drive mechanism 28 g is driven in the reverse direction, the leaf spring member 28 f (28 e) of the thread wiper holding mechanism 28 b comes into contact with the tip of the thread delivery pipe 28 a. However, at this time, the leaf spring member 28 f (28 e) bends, so that it can pass through the position of the yarn delivery pipe 28 a.
そして、 糸送出管 2 8 aから導出された糸 1 1 を、 横方向に払って仮保 持した状態で、 糸張設機構 3の糸挟持部材 3 1の可動挟持片 3 1 aと固定 挟持片 3 1 bを降下させるとともに閉じて、 糸 1 1 を挟持するようにする (第 6図③) 。  Then, while the yarn 11 drawn out from the yarn delivery pipe 28 a is temporarily held while being swept in the lateral direction, the yarn 11 is fixed to the movable holding piece 3 1 a of the yarn holding member 31 of the yarn tensioning mechanism 3. Lower the piece 3 1b and close it so that the thread 11 is clamped (Fig. 6, ③).
このとき、 糸送出管 2 8 aから導出された糸 1 1は、 横方向に払って仮 保持した状態にあるため、 糸 1 1 を、 糸張設機構 3の糸挟持部材 3 1の可 動挟持片 3 1 aと固定挟持片 3 1 bの間で、 所定精度の挟持状態の下に正 確に挟持することができる。  At this time, since the yarn 11 drawn out from the yarn delivery pipe 28 a is in a state of being temporarily held by being paid in the lateral direction, the yarn 11 is moved by the yarn holding member 3 1 of the yarn tensioning mechanism 3. The holding piece 31a and the fixed holding piece 31b can be accurately held under a holding state of a predetermined accuracy.
この状態で、 糸仮保持機構 2 6による糸 1 1の仮保持を一旦解除し、 こ れにより、 ポビン収容部 2 2に収容したポビン 2 1から糸 1 1が自由に繰 リ出されるようにして、 糸張設機構 3の糸挟持部材 3 1を、 略中間部 (天 秤機構 4の副天秤 4 2の定位置 4 2 Z近傍) の待機位置まで降下させる (第 6図④) 。  In this state, the temporary holding of the yarn 11 by the temporary yarn holding mechanism 26 is temporarily released, so that the yarn 11 can be freely fed from the pobin 21 accommodated in the pobin accommodation portion 22. Then, the thread holding member 31 of the thread tensioning mechanism 3 is lowered to a standby position substantially in the middle (near the fixed position 42Z of the sub-balance 42 of the balance mechanism 4) (Fig. 6 (1)).
次に、 糸仮保持機構 2 6による糸 1 1の仮保持を解除したまま、 糸供給 装置 2の糸選択機構 2 9を駆動することにより、 糸張設機構 3の糸挟持部 材 3 1 との間で糸 1 1が掛け渡された状態の糸送出管 2 8 aを 1段階側方 (右側) に移動させる (第 6図⑤) 。 Next, while the temporary holding of the yarn 11 by the temporary yarn holding mechanism 26 is released, the yarn selection mechanism 29 of the yarn supply device 2 is driven to thereby hold the yarn holding member 3 1 of the yarn tensioning mechanism 3 together. Between the thread delivery pipe 28 a with the thread 1 1 (Right side) (Fig. 6, ①).
そして、 糸仮保持機構 2 6による糸 1 1の仮保持を解除したまま、 ボビ ン収容部 2 2に収容したポビン 2 1から糸 1 1が自由に繰り出されるよう にして、 ブレーキモータ又はエア一モータからなる副天秤 4 2の駆動機構 4 3を駆動することによって、 副天秤 4 2を上死点の位置 4 2 Xから下死 点の位置 4 2 Yまで一旦移動させる。 そめ後、 定位置 4 2 Zに移動させる ことにより、 糸 1 1 を天秤 4 1及び副天秤 4 2に掛け渡すようにしながら、 糸張力調節機構 2 5の糸 1 1にテンションをかけるばね機構や後述の糸挟 持部材 3 1 と糸張架機構 3 3との間に張架することによって吸収される糸 長さを確保し、 糸通しを行うときに糸長さが不足することを防止するよう にする。 そして、 さらに、 糸張設機構 3の駆動機構 3 2を駆動することに よって、 糸張設機構 3の糸挟持部材 3 1を降下させる (第 6図⑥) 。  Then, while the temporary holding of the yarn 11 by the yarn temporary holding mechanism 26 is released, the yarn 11 is freely fed out from the pobin 21 stored in the bobbin storing portion 22, and the brake motor or the air motor is released. By driving the drive mechanism 43 of the sub balance 42 composed of a motor, the sub balance 42 is temporarily moved from the position 42 X of the top dead center to the position 42 Y of the bottom dead center. After that, by moving the thread 11 to the balance 41 and the sub-balance 42 by moving the thread 11 to the fixed position 4 2 Z, a spring mechanism for applying tension to the thread 11 of the thread tension adjusting mechanism 25 is provided. It secures the length of the yarn that is absorbed by being stretched between the thread holding member 31 and the thread tension mechanism 33, which will be described later, and prevents shortage of the thread length when performing threading. So that Then, by further driving the drive mechanism 32 of the thread tensioning mechanism 3, the thread holding member 31 of the thread tensioning mechanism 3 is lowered (FIG. 6⑥).
この場合、 副天秤 4 2の定位置 4 2 Zを規定するストツパ 4 2 2は、 直 流ソレノィ ド等の駆動機構を備え、 これにより、 ストツバ 4 2 zを没する ことにより、 副天秤 4 2をストツバ 4 2 zの位置を一旦通過させた後、 ス トツパ 4 2 zを突出することにより、 副天秤 4 2をストツバ 4 2 zに当接 させ、 正確に刺繍を行う定位置 4 2 Zに位置させることができるようにし ている。  In this case, the stopper 42 that defines the fixed position 4 2 Z of the sub balance 4 2 is provided with a drive mechanism such as a direct current solenoid, whereby the sub balance 4 2 After passing through the position of the stopper 4 2 z once, the auxiliary balance 42 is brought into contact with the stopper 4 2 z by protruding the stopper 4 2 z, so that the auxiliary balance 4 2 So that they can be positioned.
また、 糸挟持部材 3 1に挟持された糸 1 1 を、 糸挟持部材 3 1 と糸張架 機構 3 3との間に張架することにより、 張架した糸 1 1を、 前もって針 1 0の針孔 1 0 aに揷通された糸通し機構 6のフック部材 6 1上に載置する ようにする。  In addition, the thread 11 held between the thread holding members 3 1 is stretched between the thread holding member 3 1 and the thread tension mechanism 33, so that the stretched thread 11 is moved in advance by the needle 10. On the hook member 61 of the threading mechanism 6 passed through the needle hole 10a.
なお、 副天秤 4 2及び糸挟持部材 3 1の移動の開始順序は、 糸 1 1が天 秤 4 1及び副天秤 4 2に確実に掛け渡されるように、 適宜時間差を持たせ るようにする。 この状態で、 針棒支持機構 8の駆動機構を駆動することにより、 針棒の 支持を解除し、 糸通し機構 6の駆動機構を駆動することにより、 糸通し機 構 6のフック部材 6 1を針 1 0の針孔 1 0 aから引き抜くようにして、 針 1 0の針? L 1 0 aに糸 1 1 を揷通するとともに、 糸挟持部材 3 1の可動挟 持片 3 1 aと固定挟持片 3 1 bを開いて糸 1 1の挟持を解除するようにす る (第 6図⑦) 。 The starting order of the movement of the sub-balance 42 and the thread holding member 31 is such that there is an appropriate time difference so that the thread 11 can be reliably passed over the balance 41 and the sub-balance 42. . In this state, the drive mechanism of the needle bar support mechanism 8 is driven to release the support of the needle bar, and the drive mechanism of the threading mechanism 6 is driven to release the hook member 61 of the threading mechanism 6. Needle 10 needle by pulling out from needle hole 10 a of needle 10? While passing the thread 11 through L10a, open the movable holding piece 3 1a and the fixed holding piece 3 1b of the thread holding member 31 to release the holding of the thread 11 ( (Fig. 6⑦).
その後、 糸張設機構 3の駆動機構 3 2を駆動することによって、 糸張設 機構 3の糸挟持部材 3 1を略中間部 (天秤機構 4の副天秤 4 2の定位置 4 2 Z近傍) の待機位置まで上昇させながら、 糸張架機構 3 3を復帰させ、 待機させるようにする (第 6図⑧) 。  Then, by driving the driving mechanism 32 of the thread tensioning mechanism 3, the thread clamping member 31 of the thread tensioning mechanism 3 is moved to the substantially intermediate portion (near the fixed position 4 2 Z of the sub balance 4 2 of the balance mechanism 4). The thread tensioning mechanism 33 is returned to the standby position while being raised to the standby position (Fig. 6, ①).
