As shown in FIGS. 1 and 4, the thread wiping device 11 for the sewing machine is provided with a base plate 31 that is detachably attached to the pressing means 10, and is provided on the base plate 31 so as to be slidable substantially parallel to the thread sewing direction. 12, a pulling member 41 that pulls the needle thread 4 in the sewing direction through the groove 16 formed in the groove 12, and an actuator 40 that is attached to the substrate 31 and reciprocates the pulling member 41.

また、総合送りミシンの場合は、図4に示すように、上送り軸6と上送り足22とからなり、図5に示すように、針板上の被縫製物Mを上送り足22が上方から接した状態で送る上送り手段20を有する。前記上送り足22と前記押さえ足12は、交互に上下動させるように、前記上送り軸6と前記押さえ軸2を交互上下機構により動作させる。係る場合、ミシンの糸払い装置11は、押さえ足12に形成された溝16及び上送り足22に形成された溝26を引寄せ部材41が挿通する。   Further, in the case of a general feed sewing machine, as shown in FIG. 4, it comprises an upper feed shaft 6 and an upper feed leg 22, and as shown in FIG. It has the upper feed means 20 which sends in the state which contact | connected from upper direction. The upper feed shaft 6 and the presser foot 2 are operated by an alternate vertical mechanism so that the upper feed foot 22 and the presser foot 12 are alternately moved up and down. In this case, in the thread wiping device 11 for the sewing machine, the pulling member 41 is inserted through the groove 16 formed in the presser foot 12 and the groove 26 formed in the upper feed foot 22.

ミシンの糸払い装置11は、ミシンの押さえ手段10に取り付けられるので、ミシン本体を加工することなく簡単に取り付けることができ、しかも、ミシン本体の動力を必要としないで動作できるので、どのタイプのミシンでも簡単に取り付けることができる。また、ミシンの糸払い装置11は、図6に示すように、押さえ軸2及び針棒5の側面に配置される構成ではなく、ワイパー片に相当する引寄せ部材41が押さえ足12(及び上送り足22)に形成された溝16(26)を挿通して、針棒5と押さえ軸2を結ぶ略直線方向(送り方向、前後方向)で動作を行うので、作業者の縫製作業の障害となり難く、しかも引寄せ部材41及び駆動機構(アクチュエータ40)が被縫製物Mに接触しないので、被縫製物Mを傷つけてしまう虞がない。   Since the thread wiping device 11 of the sewing machine is attached to the presser means 10 of the sewing machine, it can be easily attached without processing the sewing machine main body, and can operate without requiring the power of the sewing machine main body. A sewing machine can be easily installed. Further, as shown in FIG. 6, the thread wiping device 11 for the sewing machine is not configured to be disposed on the side surfaces of the presser shaft 2 and the needle bar 5, but the attracting member 41 corresponding to the wiper piece is provided with the presser foot 12 (and the upper foot). Since the operation is performed in a substantially linear direction (feeding direction, front-rear direction) connecting the needle bar 5 and the pressing shaft 2 through the groove 16 (26) formed in the feeding foot 22), it is an obstacle to the sewing work of the operator. In addition, since the attracting member 41 and the drive mechanism (actuator 40) do not contact the sewing product M, there is no possibility of damaging the sewing product M.

さらに、ミシンの糸払い装置11は、図7に示すように、引寄せ部材41の糸捕捉部(係止爪)45がミシン針3の前方から後方、即ち作業者から離れる方向(縫製方向)に向かって、針糸4を払う構成なので、引寄せ部材41自体及び引寄せ部材41によって払われた針糸4の端部が作業者、被縫製物Mに接触する可能性がなく、作業に支障が出ることがない。   Further, as shown in FIG. 7, the thread wiping device 11 for the sewing machine has a direction (sewing direction) in which the thread catching portion (locking claw) 45 of the attracting member 41 is away from the front of the sewing needle 3, that is, from the operator. Since the needle thread 4 is paid toward the sewing machine 41, there is no possibility that the attracting member 41 itself and the end portion of the needle thread 4 paid by the attracting member 41 come into contact with the operator and the sewing product M. There will be no hindrance.

さらにまた、ミシンの糸払い装置11は、ミシンが総合送りタイプである場合、図6に示すように、引寄せ部材41が上送り足22の溝26を挿通するので、上送り足22の位置がどこであっても動作可能であり、例えば、図9に示すように、上送り足22が上方の位置であっても動作することができ、その結果、上送り足22を上方位置から最下位置まで移動させて糸払い動作を行わせる駆動制御が不要となり、縫製作業時間を短縮して縫製作業の効率を向上させることができる。   Furthermore, when the sewing machine is a general feed type, the thread wiping device 11 for the sewing machine has a drawing member 41 inserted through the groove 26 of the upper feed leg 22 as shown in FIG. 9, for example, as shown in FIG. 9, the upper feed leg 22 can be operated at the upper position, and as a result, the upper feed leg 22 is moved from the upper position to the lowest position. The drive control to move to the position and perform the thread wiping operation becomes unnecessary, and the sewing work time can be shortened and the efficiency of the sewing work can be improved.

以下、一本針ミシンに使用される糸払い装置の実施の形態を図1から図10に基づいて説明する。
一本針ミシンに使用される糸払い装置11は、ミシンの押さえ軸2又は押さえ足12に取りつけられる。このミシンが総合送りである場合について、説明する。総合送りミシンは、被縫製物にミシン針を突き刺した状態で送りを行うことができるミシンである。一般的に、総合送りミシンは、ミシンフレームと、ミシンフレームが載置されるミシンテーブルとを有する。ミシンフレーム内には、針上下動機構と、針振り機構と、駆動モータと、押さえ機構と、下送り機構と、上送り機構と、交互上下機構と、釜機構、糸切断機構と、各機構の駆動を制御する制御手段を備えている。
Hereinafter, an embodiment of a thread wiper used for a single needle sewing machine will be described with reference to FIGS.
A thread wiper 11 used for a single-needle sewing machine is attached to a presser shaft 2 or a presser foot 12 of the sewing machine. A case where the sewing machine is a general feed will be described. The general feed sewing machine is a sewing machine that can perform feed while a sewing needle is pierced into a sewing product. Generally, the general feed sewing machine has a sewing machine frame and a sewing machine table on which the sewing machine frame is placed. In the sewing machine frame, there are a needle up-and-down moving mechanism, a needle swinging mechanism, a drive motor, a pressing mechanism, a lower feed mechanism, an upper feed mechanism, an alternating vertical mechanism, a shuttle mechanism, a thread cutting mechanism, and each mechanism. The control means which controls the drive of is provided.

針上下動機構は、ミシン針3を保持する針棒5を上下に昇降させる。針振り機構は、針棒5の上下動に連動して針棒5を送り方向(X軸方向)に沿って揺動させ、ミシン針3が被縫製物Mを下方に貫通した状態で縫製方向に被縫製物Mを送る。駆動モータは、針棒5を上下に駆動させる。押さえ機構は、被縫製物Mを針板に向けて上方から押さえる押さえ足12と、押さえ足12を下端に取り付けた押さえ軸2を作動させる。なお、押さえ足12と押さえ軸2とで押さえ手段10を構成する。   The needle up / down movement mechanism moves the needle bar 5 holding the sewing needle 3 up and down. The needle swinging mechanism swings the needle bar 5 along the feed direction (X-axis direction) in conjunction with the vertical movement of the needle bar 5, and the sewing direction with the sewing needle 3 penetrating the workpiece M downward. The sewing product M is sent to. The drive motor drives the needle bar 5 up and down. The presser mechanism operates a presser foot 12 that presses the workpiece M toward the needle plate from above and a presser shaft 2 having the presser foot 12 attached to the lower end. The presser foot 12 and the presser shaft 2 constitute the presser means 10.

下送り機構は、駆動モータの駆動により、下送り歯が長円運動で上部が針板から出没し、被縫製物Mを送り方向に沿って送る。上送り機構は、上送り軸6に取り付けた上送り足22を、針板上の被縫製物Mに対して上方から接触させ、針棒5の昇降動作に連動して送り方向に搖動させて被縫製物Mを送る。なお、上送り足22と上送り軸6とで上送り手段20を構成する。交互上下機構は、押さえ足12の押さえ軸2と上送り軸6を交互に上下動させ、押さえ足12と上送り足22とを交互に被縫製物Mに接触させる。   The lower feed mechanism is driven by a drive motor, and the lower feed dog moves in an elliptical manner, and the upper part protrudes and retracts from the needle plate, and feeds the workpiece M along the feed direction. The upper feed mechanism causes the upper feed foot 22 attached to the upper feed shaft 6 to contact the workpiece M on the needle plate from above, and swings in the feed direction in conjunction with the lifting and lowering operation of the needle bar 5. The sewing product M is sent. The upper feed leg 22 and the upper feed shaft 6 constitute the upper feed means 20. The alternate vertical mechanism causes the presser shaft 2 and the upper feed shaft 6 of the presser foot 12 to move up and down alternately, and causes the presser foot 12 and the upper feed foot 22 to contact the sewing product M alternately.

釜機構は、針板の下方に位置し、回転して下糸を引き出す釜を備え、針板の下方まで針落ちを行ったミシン針が上昇する際に形成される上糸のループを、回転する釜に設けられた剣先が捕捉して下糸と絡ませることにより縫い目を形成する。糸切断機構は、動メスと、動メスと協働して針糸4を切断する固定メスと、動メスを駆動する駆動部とからなり、下送り歯の下方において縫製後の針糸4を切断する。   The shuttle mechanism is equipped with a hook that is positioned below the needle plate and rotates to pull out the lower thread, and rotates the loop of the upper thread that is formed when the sewing needle that has dropped the needle down to the lower part of the needle plate rises. The sword tip provided on the hook is caught and entangled with the lower thread to form a seam. The thread cutting mechanism includes a moving knife, a fixed knife that cuts the needle thread 4 in cooperation with the moving knife, and a drive unit that drives the moving knife, and the needle thread 4 after sewing is placed below the lower feed dog. Disconnect.

制御手段は、上記各機構の駆動の制御を行い、前踏み位置と踏み返し位置とに揺動操作されるミシンペダルとを備えている。制御手段は、縫製終了の際、ミシンペダルの後踏み動作による糸切り信号が検出されると、駆動部が駆動して動メスが下送り歯の針穴下方まで往復動して上糸及び下糸の一部を固定メスとの協働により切断する。   The control means includes a sewing machine pedal that controls the driving of each of the above-described mechanisms and is swingably operated between the front stepping position and the stepping back position. When the thread trimming signal is detected by the back-depressing operation of the sewing pedal at the end of sewing, the control means drives the drive unit so that the moving knife moves back and forth below the needle hole of the lower feed dog to move the upper thread and lower thread. A part of the thread is cut in cooperation with the fixed knife.

糸払い装置11は、図4に示すように、上記総合送りミシンの押さえ軸2の押さえ足12に固定される。押さえ足12は、図1、2に示すように、先端が湾曲した接地板13と、接地板13の後端に連接された傾斜部材14と、傾斜部材14の上端に形成された連結片15とからなり、一体形成されている。押さえ足12は、接地板13及び傾斜部材14の略中央に挿通溝16が形成されている。押さえ足12は、図4に示すように、連結片15を押さえ軸2の下端に形成された割溝17に差し込みねじ止めされて、押さえ軸2に固定される。押さえ軸2に固定された押さえ足12の挿通溝16は、X軸方向(前後方向、送り方向)に向かって伸びている。   As shown in FIG. 4, the thread wiper 11 is fixed to the presser foot 12 of the presser shaft 2 of the general feed sewing machine. As shown in FIGS. 1 and 2, the presser foot 12 includes a ground plate 13 having a curved tip, an inclined member 14 connected to the rear end of the ground plate 13, and a connecting piece 15 formed at the upper end of the inclined member 14. And is formed as a single piece. The presser foot 12 has an insertion groove 16 formed substantially at the center of the ground plate 13 and the inclined member 14. As shown in FIG. 4, the presser foot 12 is fixed to the presser shaft 2 by inserting the connecting piece 15 into a split groove 17 formed at the lower end of the presser shaft 2 and screwing it. The insertion groove 16 of the presser foot 12 fixed to the presser shaft 2 extends in the X-axis direction (front-rear direction, feed direction).

上送り足22は、図3に示すように、先端が湾曲した接地板23と、接地板23の後部に略垂直に接続された連結部材25とからなり、一体成形されている。上送り足22は、接地板23にミシン針3を挿通する挿通穴24と挿通穴24と連通して針糸4をガイドするガイド溝27が形成され、連結部材25の略中央にガイド溝27と連通する挿通溝26が形成されている。上送り足22は、連結部材25の上端に形成された取付穴28に上送り軸6の下部を差し込み、ねじ止めされて上送り軸6に固定される。上送り軸6に固定された上送り足22の挿通溝26は、X軸方向(前後方向、送り方向)に向かって伸びている。   As shown in FIG. 3, the upper feed leg 22 includes a ground plate 23 having a curved tip and a connecting member 25 connected substantially perpendicularly to the rear portion of the ground plate 23 and is integrally formed. The upper feed leg 22 is formed with an insertion hole 24 through which the sewing needle 3 is inserted into the ground plate 23 and a guide groove 27 that communicates with the insertion hole 24 and guides the needle thread 4. An insertion groove 26 that communicates with each other is formed. The upper feed leg 22 is fixed to the upper feed shaft 6 by inserting the lower part of the upper feed shaft 6 into an attachment hole 28 formed at the upper end of the connecting member 25 and screwing. The insertion groove 26 of the upper feed leg 22 fixed to the upper feed shaft 6 extends in the X-axis direction (front-rear direction, feed direction).

糸払い装置11は、図1に示すように、押さえ足12に着脱可能に取り付けられる基板31と、基板31に、糸の縫い方向(X軸方向)と略平行にスライド可能に設けられ、押さえ足12に形成された挿通溝16及び上送り足22に形成された挿通溝26を挿通して、針糸4を縫製方向(ミシン針からみて押さえ軸方向、作業者の反対方向)に引き寄せる引寄せ部材41と、基板31に取り付けられ、前記引寄せ部材41を往復動させるアクチュエータ40とからなる。   As shown in FIG. 1, the thread wiper 11 is provided with a base plate 31 that is detachably attached to the presser foot 12, and is provided on the base board 31 so as to be slidable substantially parallel to the sewing direction of the thread (X-axis direction). Pulling through the insertion groove 16 formed in the foot 12 and the insertion groove 26 formed in the upper feed leg 22 and pulling the needle thread 4 in the sewing direction (the pressing shaft direction as viewed from the sewing needle, the direction opposite to the operator). The moving member 41 includes an attracting member 41 and an actuator 40 that is attached to the substrate 31 and reciprocates the attracting member 41.

基板31は、略L字状に形成され、側板32と折曲板33からなる。基板31の側板32の前部が押さえ足12の傾斜部材14にネジ18によって着脱可能に固定されている。側板32には、X軸方向に伸びるガイド長穴35が形成されている。基板31には、前記ガイド長穴35に案内される摺動軸36を備えたスライド片37が設けられている。摺動軸36は、ネジ39の頭部によってガイド長穴35から外れないように規制されている。   The substrate 31 is formed in a substantially L shape and includes a side plate 32 and a bent plate 33. A front portion of the side plate 32 of the substrate 31 is detachably fixed to the inclined member 14 of the presser foot 12 by screws 18. The side plate 32 is formed with a guide slot 35 extending in the X-axis direction. The substrate 31 is provided with a slide piece 37 having a slide shaft 36 guided by the guide slot 35. The sliding shaft 36 is regulated so as not to be detached from the guide slot 35 by the head of the screw 39.

基板31の折曲板33には、アクチュエータ40が取り付けられている。アクチュエータ40は、電磁式、空圧式、油圧式等、特に限定されるものではないが、電磁式アクチュエータ(ソレノイド)として説明する。電磁式アクチュエータ40は、前後方向(X軸方向)に出没する駆動軸42を備え、当該駆動軸42がスライド片37に固定され、スライド片37を前後方向にスライドさせる。電磁式アクチュエータ40は、ミシンの制御手段に電気的に接続されている。   An actuator 40 is attached to the bent plate 33 of the substrate 31. The actuator 40 is not particularly limited, and is described as an electromagnetic actuator (solenoid). The electromagnetic actuator 40 includes a drive shaft 42 that protrudes and retracts in the front-rear direction (X-axis direction). The drive shaft 42 is fixed to the slide piece 37 and slides the slide piece 37 in the front-rear direction. The electromagnetic actuator 40 is electrically connected to the sewing machine control means.

スライド片37には、針糸4を縫製方向に引き寄せる引寄せ部材41がネジ43によって取り付けられている。引寄せ部材41は、薄い金属板の折曲によって形成され、先端に糸を捕捉する係止爪45が形成されている。引寄せ部材41は、押さえ足12の挿通溝16と上送り足22の挿通溝26内を挿通し、針糸4を縫製方向に引き寄せることができる。   A pulling member 41 for pulling the needle thread 4 in the sewing direction is attached to the slide piece 37 with a screw 43. The attracting member 41 is formed by bending a thin metal plate, and a locking claw 45 that captures a thread is formed at the tip. The drawing member 41 can be inserted through the insertion groove 16 of the presser foot 12 and the insertion groove 26 of the upper feed leg 22 to draw the needle thread 4 in the sewing direction.

総合送りミシンの動作について説明する。ミシンペダルの中立位置から、前踏み動作が検知されると、検知信号が制御手段に送られ、制御手段は、踏み込み量に応じた速度で駆動モータを駆動する。そして、駆動モータの駆動により、ミシン針3が上下方向に昇降し、同時に釜が回転する。ミシン針3が被縫製物Mの貫通後に形成される針糸4のループに釜の剣先が引っ掛かり、ミシン針3の針糸4と釜の下糸と絡み合い、縫い目が形成される。   The operation of the general feed sewing machine will be described. When a forward stepping action is detected from the neutral position of the sewing pedal, a detection signal is sent to the control means, and the control means drives the drive motor at a speed corresponding to the depression amount. And by the drive of a drive motor, the sewing machine needle | hook 3 raises / lowers up and down, and a shuttle rotates simultaneously. The hook tip of the hook is caught in the loop of the needle thread 4 formed after the sewing needle 3 penetrates the sewing product M, and the needle thread 4 of the sewing needle 3 and the lower thread of the hook are intertwined to form a seam.

また、ミシンペダルが中立位置に復帰されると、図4に示すように、駆動モータの駆動が停止し、ミシン針3及び上送り足22が、上下動の最上部位置で停止を行う。押さえ足12は、その下面が被縫製物Mの上面に当接した状態で停止する。そして、ミシンペダルの中立位置から、ミシンペダルの後踏み動作が検知されると、検知信号(糸切り信号)が制御手段に送られる。制御手段は、糸切断機構の駆動部の駆動する制御を行う。針板の下方において動メス及び固定メスによって上糸及び下糸が切断される。切断後には、ミシン針3の糸通し穴に挿通された針糸4が、被縫製物Mを貫通したままの状態となっている。   Further, when the sewing pedal is returned to the neutral position, as shown in FIG. 4, the drive motor is stopped, and the sewing needle 3 and the upper feed leg 22 are stopped at the uppermost position of the vertical movement. The presser foot 12 stops in a state where the lower surface thereof is in contact with the upper surface of the sewing product M. Then, when a backward stepping operation of the sewing pedal is detected from the neutral position of the sewing pedal, a detection signal (thread trimming signal) is sent to the control means. The control means performs control to drive the drive unit of the yarn cutting mechanism. The upper thread and the lower thread are cut by the moving knife and the fixed knife below the needle plate. After the cutting, the needle thread 4 inserted through the threading hole of the sewing needle 3 remains in the state of passing through the sewing product M.

次に制御手段は、図5に示すように、駆動モータを駆動して上送り足22を下降させる。上送り足22と押さえ足12は、各底面がそれぞれ被縫製物Mの上面に当接した状態で停止する。ミシン針3は、上下動の最上部で停止したままである。ミシン針3と、上送り足22及び押さえ足12との間には、スペースが形成される。   Next, the control means drives the drive motor to lower the upper feed leg 22 as shown in FIG. The upper feed foot 22 and the presser foot 12 are stopped in a state where each bottom surface is in contact with the top surface of the sewing product M. The sewing needle 3 remains stopped at the top of the vertical movement. A space is formed between the sewing needle 3 and the upper feed foot 22 and the presser foot 12.

次に、制御手段は、図6に示すように、電磁アクチュエータ40を駆動して、引寄せ部材41を往復動させる。引寄せ部材41の先端に設けられた係止爪45は、押さえ足12の挿通溝16及び上送り足22の挿通溝26を挿通して、ミシン針3の下端と上送り足22及び押さえ足12との間のスペースを通過(往動)し、図7に示すように、引き戻される(復動する)ときに、針糸4を捕捉して針糸4の切断端部を被縫製物Mの上方に引き抜いて保持する。糸払い装置11の糸払い動作が完了した後、制御手段によって、図8に示すように、上送り足22が上停止位置に戻される。上送り足22には、挿通溝26と連通するガイド溝27が形成されているので、上送り足22が上方に移動すると、針糸4が挿通溝26からガイド溝27に案内され、上送り足22が針糸4の切断端部を、引寄せ部材41の係止爪45に保持されている状態から引き抜くことがなく、その保持した状態が維持される。   Next, the control means drives the electromagnetic actuator 40 to reciprocate the attracting member 41 as shown in FIG. The locking claw 45 provided at the tip of the attracting member 41 is inserted through the insertion groove 16 of the presser foot 12 and the insertion groove 26 of the upper feed foot 22, and the lower end of the sewing needle 3, the upper feed foot 22 and the presser foot. 12, when the needle thread 4 is caught (returned) as shown in FIG. 7, the needle thread 4 is captured and the cut end of the needle thread 4 is sewn to the sewing product M. Pull out above and hold. After the yarn wiper operation of the yarn wiper 11 is completed, the upper feed leg 22 is returned to the upper stop position by the control means as shown in FIG. Since the upper feed leg 22 is formed with a guide groove 27 that communicates with the insertion groove 26, when the upper feed leg 22 moves upward, the needle thread 4 is guided from the insertion groove 26 to the guide groove 27, and the upper feed leg 22 The foot 22 does not pull out the cut end portion of the needle thread 4 from the state held by the locking claw 45 of the drawing member 41, and the held state is maintained.

総合送りミシンは、上記動作に限定されるものではなく、ミシン針3が最下位置から最上部に上昇中に糸切断機構が針糸の切断を行うものがあり、ミシン針3及び上送り足22が最上部位置で停止を行う(図4参照)。押さえ足12は、その下面が被縫製物Mの上面に当接した状態で停止する。この状態で、制御手段は、図9に示すように、電磁アクチュエータ40を駆動して、引寄せ部材41を往復動させる。引寄せ部材41の先端に設けられた係止爪45は、押さえ足12の挿通溝16を挿通して、押さえ足12と上送り足22との間のスペースを通過(往動)して、図8に示すように、引き戻される(復動する)ときに、針糸4を捕捉して針糸4の切断端部を被縫製物Mの上方に引き抜いて保持して停止する。上送り足22は、ガイド溝27と挿通溝26が連通しているので、図7に示すように、上送り足22を下方に移動させても、針糸4がガイド溝27から挿通溝26に案内され、上送り足22が針糸4の切断端部を、引寄せ部材41の係止爪45に保持されている状態から引き抜くことがなく、その保持した状態が維持される。   The total feed sewing machine is not limited to the above-described operation, and there is one in which the thread cutting mechanism cuts the needle thread while the sewing needle 3 is raised from the lowest position to the uppermost position. 22 stops at the uppermost position (see FIG. 4). The presser foot 12 stops in a state where the lower surface thereof is in contact with the upper surface of the sewing product M. In this state, the control means drives the electromagnetic actuator 40 to reciprocate the attracting member 41 as shown in FIG. The locking claw 45 provided at the tip of the pulling member 41 passes through the insertion groove 16 of the presser foot 12 and passes (forwards) through the space between the presser foot 12 and the upper feed foot 22. As shown in FIG. 8, when the needle thread 4 is pulled back (returned), the needle thread 4 is captured and the cut end portion of the needle thread 4 is pulled out above the sewing product M and is stopped. Since the upper feed leg 22 communicates with the guide groove 27 and the insertion groove 26, as shown in FIG. 7, even if the upper feed leg 22 is moved downward, the needle thread 4 moves from the guide groove 27 to the insertion groove 26. Thus, the upper feed leg 22 does not pull out the cut end portion of the needle thread 4 from the state held by the locking claw 45 of the attracting member 41, and the held state is maintained.

総合送りミシンは、図5に示すように、ミシン針3の最上部での停止位置において、上送り足22と押さえ足12の両方がほぼ同時に被縫製物Mの上面に接触するが、上送り足22と押さえ足12の上下量のバランスを変える場合があり、係る場合、どちらか一方が高い状態で停止する。糸払い装置11は、上送り足22と押さえ足12のどちらか一方が高い状態でも、引寄せ部材41が往復動して、糸払い作業を行うことができる。図9を参照して前述したように、上送り足22が押さえ足12より高い位置にある時は、引寄せ部材41の先端に設けられた係止爪45が、押さえ足12の挿通溝16を挿通して、押さえ足12と上送り足22との間のスペースを通過(往動)して、針糸4の糸払いを行う。また、図10に示すように、押さえ足12が上送り足22より高い位置にある時は、引寄せ部材41の先端に設けられた係止爪45が、押さえ足12の挿通溝16及び上送り足22の挿通溝26を挿通して、押さえ足12とミシン針3との間のスペースを通過(往動)して、針糸4の糸払いを行う。このように、ミシンの糸払い装置11は、上送り足22及び押さえ足12がどの位置にあっても、糸払い動作を行うことができる。   As shown in FIG. 5, in the total feed sewing machine, both the upper feed foot 22 and the presser foot 12 contact the upper surface of the sewing product M almost simultaneously at the stop position at the uppermost portion of the sewing needle 3, but the upper feed In some cases, the balance between the vertical amount of the foot 22 and the presser foot 12 may be changed. The yarn wiper 11 can perform the yarn wiper operation by the reciprocating movement of the attracting member 41 even when one of the upper feed foot 22 and the presser foot 12 is high. As described above with reference to FIG. 9, when the upper feed leg 22 is at a position higher than the presser foot 12, the locking claw 45 provided at the tip of the attracting member 41 is inserted into the insertion groove 16 of the presser foot 12. Is passed through the space between the presser foot 12 and the upper feed foot 22 (forward movement), and the needle thread 4 is wiped off. As shown in FIG. 10, when the presser foot 12 is at a position higher than the upper feed foot 22, the locking claw 45 provided at the tip of the attracting member 41 is inserted into the insertion groove 16 and the upper foot of the presser foot 12. The needle thread 4 is wiped by passing through the insertion groove 26 of the feed leg 22 and passing through the space between the presser foot 12 and the sewing needle 3 (forward movement). Thus, the thread wiping device 11 for the sewing machine can perform the thread wiping operation regardless of the position of the upper feed leg 22 and the presser foot 12.

ミシンの糸払い装置11は、ミシンの押さえ足12に着脱可能に取り付けることができるので、ミシン本体の加工を必要とせず、どのタイプのミシンであっても、簡単に取り付けることができる。また、ミシンの糸払い装置11は、作業者からみて、押さえ軸2の後方(ミシンの針棒5の反対側)に取り付けられ、ワイパー片に相当する引寄せ部材41が押さえ足12及び上送り足22に形成された溝16,26内を挿通して、針棒5と押さえ軸2を結ぶ略直線方向(送り方向、前後方向)で往復動作を行うので、作業者の縫製作業の障害となり難い。しかも引寄せ部材41及び駆動機構(アクチュエータ40)が被縫製物Mに接触しないので、被縫製物Mを傷つけてしまう虞がない。即ち、引寄せ部材41は、押さえ足12の挿通溝16内で前後方向の往復動作を行うので、作業者及び被縫製物Mに接触する虞が極めて少ない。   Since the thread wiping device 11 of the sewing machine can be detachably attached to the presser foot 12 of the sewing machine, it is not necessary to process the sewing machine body, and any type of sewing machine can be easily attached. The thread wiping device 11 for the sewing machine is attached to the rear side of the presser shaft 2 (opposite side of the needle bar 5 of the sewing machine) as viewed from the operator, and the pulling member 41 corresponding to the wiper piece has the presser foot 12 and the upper feed. Since it reciprocates in a substantially linear direction (feeding direction, front-rear direction) connecting the needle bar 5 and the pressing shaft 2 through the grooves 16 and 26 formed in the foot 22, it becomes an obstacle to the sewing work of the operator. hard. Moreover, since the pulling member 41 and the drive mechanism (actuator 40) do not contact the sewing product M, there is no possibility that the sewing product M will be damaged. That is, the pulling member 41 reciprocates in the front-rear direction within the insertion groove 16 of the presser foot 12, so that there is very little possibility of contact with the operator and the sewing product M.

さらに、ミシンの糸払い装置11は、引寄せ部材41の糸捕捉部(係止爪)45がミシン針3の前方から後方、即ち作業者から離れる方向(縫製方向)に向かって、針糸4を払う構成なので、引寄せ部材41自体及び引寄せ部材41によって払われた針糸4の端部が作業者、被縫製物Mに接触する可能性がなく、作業に支障が出ることがない。特に、引寄せ部材41の糸捕捉部(係止爪)45が、図7に示すように、針糸4の残端部を押さえ足12の挿通溝16内に引き込むので、針糸4の残端部が作業者、被縫製物Mに接触することがない。   Further, the thread wiping device 11 of the sewing machine has the needle thread 4 in a direction in which the thread catching portion (locking claw) 45 of the attracting member 41 is away from the front of the sewing needle 3, that is, away from the operator (sewing direction). Therefore, there is no possibility that the attracting member 41 itself and the end portion of the needle thread 4 paid by the attracting member 41 will contact the operator and the sewing product M, and the work will not be hindered. In particular, as shown in FIG. 7, the thread catching portion (locking claw) 45 of the attracting member 41 draws the remaining end portion of the needle thread 4 into the insertion groove 16 of the presser foot 12. The end portion does not contact the worker and the sewing product M.

さらにまた、ミシンの糸払い装置11は、ミシンが総合送りタイプである場合であっても、引寄せ部材41が上送り足22の溝26を挿通するので、上送り足22が上方の位置であっても作動することができ、上送り足22を上方位置から最下位置まで移動させて糸払い動作を行わせる駆動制御が不要となり、縫製作業時間を短縮して縫製作業の効率を向上させることができる。また、糸払い装置11は、上送り足22の位置に影響されずに、糸払いを行うことができるので、上送り手段20を備えていない下送りミシンであっても、押さえ手段10に取り付けて使用することができる。   Furthermore, in the thread wiping device 11 for the sewing machine, even when the sewing machine is a general feed type, the pulling member 41 passes through the groove 26 of the upper feed leg 22 so that the upper feed leg 22 is at the upper position. Even if there is, it is possible to operate, the drive control for moving the upper feed foot 22 from the upper position to the lowest position and performing the thread wiping operation becomes unnecessary, shortening the sewing work time and improving the efficiency of the sewing work. be able to. Further, since the thread wiper 11 can perform thread wipe without being affected by the position of the upper feed leg 22, even the lower feed sewing machine not provided with the upper feed means 20 is attached to the presser means 10. Can be used.

上記実施の形態における糸払い装置は、一本針ミシンに使用されるものであるが、多本針ミシンにも使用することができる。以下、多本針ミシンに使用される糸払い装置の実施の形態を図11、図12に基づいて説明する。多本針ミシンに使用される糸払い装置51は、ミシンの押さえ軸2又は押さえ足52に取りつけられる。ミシンの説明は、上述した通りなので、説明を省略する。   The yarn wiping device in the above embodiment is used for a single needle sewing machine, but can also be used for a multi-needle sewing machine.

上記実施の形態では、被縫製物Mを押さえる押さえ足12,52に取り付けられる糸払い装置11,51について説明した。次に、ミシンのミシンヘッド8にネジ等の固定手段により取り付けられる糸払い装置101の実施の形態を説明する。まず、ミシンの糸払い装置101の概要について説明する。ミシンの糸払い装置101は、図13に示すように、被縫製物Mを押さえる押さえ足82と針棒5を備えたミシンヘッド8に取り付けられ、ミシンの糸切断機構によって切断された針糸4を払う糸払い装置である。糸払い装置101は、ミシンヘッド8に着脱可能に取り付けられる基板111と、基板111に、針糸4の縫い方向にスライド可能に設けられ、押さえ足82に形成された溝86を挿通して、針糸4を縫製方向に引き寄せる引寄せ部材131と、基板111に取り付けられ、前記引寄せ部材131を往復動させるアクチュエータ90とからなる。   In the above-described embodiment, the thread wipers 11 and 51 attached to the presser feet 12 and 52 for pressing the sewing product M have been described. Next, an embodiment of the thread wiper 101 that is attached to the sewing machine head 8 of the sewing machine by fixing means such as screws will be described. First, the outline of the thread wiping device 101 for a sewing machine will be described. As shown in FIG. 13, the thread wiping device 101 for the sewing machine is attached to a sewing head 8 having a presser foot 82 for holding the sewing product M and a needle bar 5, and the needle thread 4 cut by a thread cutting mechanism of the sewing machine. Is a thread wiper. The thread wiping device 101 is detachably attached to the sewing machine head 8, and is provided on the board 111 so as to be slidable in the sewing direction of the needle thread 4, and is inserted through a groove 86 formed in the presser foot 82. It comprises a drawing member 131 that draws the needle thread 4 in the sewing direction, and an actuator 90 that is attached to the substrate 111 and reciprocates the drawing member 131.

ミシンが総合送りミシンの場合は、図16に示すように、上送り手段99と押さえ手段89を有する。上送り手段99は、上送り軸6と上送り足92とからなり、針板上の被縫製物Mを上送り足92が上方から接した状態で送る。押さえ手段89は、押さえ軸2と押さえ足82とからなり、針板上の被縫製物Mを押さえ足82が針板に向けて押さえる。さらに総合送りミシンは、前記上送り足92と前記押さえ足82を交互に上下動させるように、前記上送り軸6と前記押さえ軸2を交互に動作させる交互上下機構とを有する。この被縫製物を押さえる押さえ足82と被縫製物Mを送る上送り足92と針棒5が、総合送りミシンのミシンヘッド8に設けられている。このミシンヘッド8に取り付けられる糸払い装置101は、図13に示すように、引寄せ部材131が押さえ足82に形成された溝86及び上送り足92に形成された溝96を挿通して、針糸4を縫製方向に引き寄せる構成となる。なお、縫製方向とは、被縫製物Mを縫製する方向であって、被縫製物Mを送る方向でもある(図15のB方向)。   When the sewing machine is a general feed sewing machine, it has an upper feed means 99 and a pressing means 89 as shown in FIG. The upper feed means 99 includes the upper feed shaft 6 and the upper feed foot 92, and feeds the workpiece M on the needle plate in a state where the upper feed foot 92 is in contact with the top. The presser means 89 includes the presser shaft 2 and the presser foot 82, and presses the workpiece M on the needle plate toward the needle plate. Further, the total feed sewing machine has an alternate vertical mechanism for alternately operating the upper feed shaft 6 and the presser shaft 2 so that the upper feed foot 92 and the presser foot 82 are alternately moved up and down. A presser foot 82 for pressing the workpiece, an upper feed leg 92 for feeding the workpiece M, and the needle bar 5 are provided on the sewing head 8 of the general feed sewing machine. In the thread wiper 101 attached to the sewing head 8, as shown in FIG. 13, the attracting member 131 is inserted through the groove 86 formed in the presser foot 82 and the groove 96 formed in the upper feed foot 92, The needle thread 4 is pulled in the sewing direction. The sewing direction is a direction in which the sewing product M is sewn, and is also a direction in which the sewing product M is sent (direction B in FIG. 15).

ミシンの糸払い装置101は、ミシン本体の動力を必要としないで動作できるので、どのタイプのミシンでも簡単に取り付けることができる。また、ミシンの糸払い装置101は、押さえ軸2及び針棒5の側面に配置される構成ではなく、ワイパー片に相当する引寄せ部材131が押さえ足82(及び上送り足92)に形成された溝86(96)を挿通して、針棒5と押さえ軸2を結ぶ略直線方向(送り方向、前後方向)で動作を行うので、作業者の縫製作業の障害となり難く、しかも引寄せ部材131及び駆動機構(アクチュエータ90)が被縫製物Mに接触しないので、被縫製物Mを傷つけてしまう虞がない。   Since the thread wiping device 101 of the sewing machine can operate without requiring the power of the sewing machine body, any type of sewing machine can be easily attached. Further, the thread wiping device 101 for the sewing machine is not configured to be disposed on the side surfaces of the presser shaft 2 and the needle bar 5, but a drawing member 131 corresponding to a wiper piece is formed on the presser foot 82 (and the upper feed foot 92). Since the operation is performed in a substantially linear direction (feeding direction, front-rear direction) connecting the needle bar 5 and the pressing shaft 2 through the groove 86 (96), it is difficult for the operator to sew the sewing work, and the drawing member Since 131 and the drive mechanism (actuator 90) do not contact the sewing product M, there is no possibility of damaging the sewing product M.

さらに、ミシンの糸払い装置101は、図26に示すように、引寄せ部材131の糸捕捉部(係止爪)132がミシン針3の前方から後方、即ち作業者から離れる方向に向かって、針糸4を払う構成なので、引寄せ部材131自体及び引寄せ部材131によって払われた針糸4の端部が作業者、被縫製物Mに接触する可能性がなく、作業に支障が出ることがない。   Further, as shown in FIG. 26, the thread wiping device 101 for the sewing machine has a thread catching portion (locking claw) 132 of the attracting member 131 from the front of the sewing needle 3 to the rear, that is, in a direction away from the operator. Since it is the structure which pays the needle thread | yarn 4, the edge part of the needle thread | yarn 4 paid by the attracting member 131 itself and the attracting member 131 does not have a possibility of contacting an operator and the to-be-sewn material M, and a trouble will arise. There is no.

さらに、糸払い装置101の実施の形態を図13から図26に基づいて説明する。なお、ミシンは、前述した総合送りミシンであって、針棒5にミシン針3,3が2本取り付けられた二本針ミシンで説明する。図16に示すように、二本針ミシンのミシンヘッド8には、ミシン針3,3を保持する針棒5と、押さえ足82を下端に取り付けた押さえ軸2と、上送り足92を取り付けた上送り軸6が配置されている。   Further, an embodiment of the yarn wiper 101 will be described with reference to FIGS.

The substrate 111 is provided with a slide piece 121 having a rectangular slide shaft 122 guided by the guide slot 115 (see FIG. 24). 22 and 23, since the sliding shaft 122 is formed in a rectangular shape, the sliding shaft 122 is in surface contact with the upper and lower edges of the guide slot 115 and guided to the guide slot 115 without rotating. . The sliding shaft 122 is regulated by a screw 123 and a nut 123A so as not to be detached from the guide slot 115.

図24に示すように、スライド片121は、略直角に接続板124が形成され、接続板124の下部に取付板125が設けられている。図26に示すように、この取付板125の両側には、一対のミシン針3,3の針糸4,4をそれぞれ縫製方向に引き寄せる一対の引寄せ部材131,131がネジによって取り付けられている。引寄せ部材131は、薄い金属板の折曲によって形成され、先部に糸を捕捉する係止爪132が形成されている。係止爪132は、先端が傾斜し、後端が直角となっており、後端で針糸4を捕捉する。一対の引寄せ部材131,131は、押さえ足82の一対の挿通孔86,86と上送り足92の一対の挿通孔96,96内を挿通し、針糸4,4を縫製方向に引き寄せることができる。なお、一対の引寄せ部材131,131の係止爪(糸捕捉部)132,132の向きは、ミシン針3,3の針糸4,4の捕捉する位置に合わせて変更される技術事項であり、両方とも内側に向けたり、外側に向けたりする場合等、特に方向に限定されるものではない。   As shown in FIG. 24, the slide piece 121 has a connection plate 124 formed at a substantially right angle, and a mounting plate 125 is provided below the connection plate 124. As shown in FIG. 26, a pair of attracting members 131 and 131 for attracting the needle threads 4 and 4 of the pair of sewing needles 3 and 3 in the sewing direction are attached to both sides of the mounting plate 125 by screws. . The attracting member 131 is formed by bending a thin metal plate, and a locking claw 132 that captures a thread is formed at the tip. The locking claw 132 is inclined at the front end and has a right end at the rear end, and captures the needle thread 4 at the rear end. The pair of drawing members 131 and 131 are inserted through the pair of insertion holes 86 and 86 of the presser foot 82 and the pair of insertion holes 96 and 96 of the upper feed leg 92 to draw the needle threads 4 and 4 in the sewing direction. Can do. The direction of the locking claws (thread catching portions) 132, 132 of the pair of attracting members 131, 131 is a technical matter that is changed according to the position where the needle threads 4, 4 of the sewing needles 3, 3 are captured. There are no particular restrictions on the direction, such as when both are directed inward or outward.

図22,23に示すように、基板111の上部には、略L字状の取付板135を介してアクチュエータ90が取り付けられている。取付板135は、略直角に折曲され、当接板136と載置板137とからなる。当接板136は、基板111にネジ等により固定され、載置板137にアクチュエータ90が取り付けられている。アクチュエータ90は、電磁式、空圧式、油圧式等、特に限定されるものではないが、電磁式アクチュエータ(ソレノイド)として説明する。電磁式アクチュエータ90は、上下方向に出没する駆動軸91を備え、当該駆動軸91がスライド片121に連係手段140を介して連結され、スライド片121を前後方向にスライドさせる。電磁式アクチュエータ90は、ミシンの制御手段に電気的に接続されている。   As shown in FIGS. 22 and 23, the actuator 90 is attached to the upper portion of the substrate 111 via a substantially L-shaped attachment plate 135. The mounting plate 135 is bent at a substantially right angle and includes a contact plate 136 and a mounting plate 137. The contact plate 136 is fixed to the substrate 111 with screws or the like, and the actuator 90 is attached to the mounting plate 137. The actuator 90 is not particularly limited, and is described as an electromagnetic actuator (solenoid). The electromagnetic actuator 90 includes a drive shaft 91 that protrudes and protrudes in the vertical direction, and the drive shaft 91 is connected to the slide piece 121 via the linkage unit 140 to slide the slide piece 121 in the front-rear direction. The electromagnetic actuator 90 is electrically connected to the sewing machine control means.

連係手段140は、図22に示すように、第1のリンク部材141と第2のリンク部材142とからなる。第1のリンク部材141は、基板111の上部に回動可能に取り付けられ、第1のアーム143と第2のアーム144が形成されている。第1のアーム143には、取付長孔143aが設けられている。図19に示すように、前記電磁式アクチュエータ90の駆動軸91には、円軸状の連結部材145が取り付けられている。連結部材145には、差込溝146が形成され、図22,23に示すように、当該差込溝146に第1のアーム143が差し込まれている。第1のアーム143は、これの取付長孔143aに連結部材145に設けられた連結軸147が摺動可能に差し込まれ、連結部材145に回動可能に連結されている。図25に示すように、第2のリンク部材142は、長板状に形成され、図22,23に示すように、一方が第2のアーム144に回動可能に連結され、他方がスライド片121のネジ123の胴部123Bに回動可能に連結されている。   As shown in FIG. 22, the linking means 140 includes a first link member 141 and a second link member 142. The first link member 141 is rotatably attached to the upper portion of the substrate 111, and a first arm 143 and a second arm 144 are formed. The first arm 143 is provided with an attachment long hole 143a. As shown in FIG. 19, a circular shaft-like connecting member 145 is attached to the drive shaft 91 of the electromagnetic actuator 90. An insertion groove 146 is formed in the connecting member 145, and the first arm 143 is inserted into the insertion groove 146 as shown in FIGS. In the first arm 143, a connecting shaft 147 provided in the connecting member 145 is slidably inserted into the attachment long hole 143a of the first arm 143, and the first arm 143 is rotatably connected to the connecting member 145. As shown in FIG. 25, the second link member 142 is formed in a long plate shape, and as shown in FIGS. 22 and 23, one is rotatably connected to the second arm 144, and the other is a slide piece. It is rotatably connected to the body 123B of the screw 123 of 121.

総合送りミシンの動作は、上述した通り、ミシンペダルの前踏み動作が検知されると、検知信号が制御手段に送られ、駆動モータが駆動して、ミシン針3,3が上下方向に昇降し、同時に釜が回転して、縫い目が形成される。ミシンペダルが復帰すると、駆動モータの駆動が停止し、ミシン針3,3及び上送り足92が、上下動の最上部位置で停止を行う。押さえ足82は、その下面が被縫製物Mの上面に当接した状態で停止する。ミシンペダルの後踏み動作が検知されると、検知信号(糸切り信号)が制御手段に送られ、糸切断機構の駆動部の駆動する制御が行われ、上糸及び下糸が切断される。切断後には、ミシン針3,3の糸通し穴に挿通された針糸4が、被縫製物Mを貫通したままの状態となっている。   As described above, the operation of the general feed sewing machine is as follows. When the front stepping action of the sewing pedal is detected, a detection signal is sent to the control means, the drive motor is driven, and the sewing needles 3 and 3 are moved up and down. At the same time, the shuttle rotates to form a seam. When the sewing pedal returns, the drive motor stops driving, and the sewing needles 3 and 3 and the upper feed leg 92 stop at the uppermost position of the vertical movement. The presser foot 82 stops in a state where the lower surface thereof is in contact with the upper surface of the sewing product M. When the back-depressing operation of the sewing pedal is detected, a detection signal (thread trimming signal) is sent to the control means, and the drive of the thread cutting mechanism is controlled to cut the upper thread and the lower thread. After the cutting, the needle thread 4 inserted into the threading holes of the sewing needles 3 and 3 remains in the state of passing through the sewing product M.

次に制御手段は、図13に示すように、駆動モータを駆動して上送り足92を下降させ、上送り足92と押さえ足82を、各底面がそれぞれ被縫製物Mの上面に当接した状態で停止させる。ミシン針3,3は、上下動の最上部で停止したままである。ミシン針3,3と、上送り足92及び押さえ足82との間には、スペースが形成される。   Next, as shown in FIG. 13, the control means drives the drive motor to lower the upper feed leg 92, and the upper feed leg 92 and the presser foot 82 come into contact with the upper surface of the sewing product M, respectively. Stop in the state. The sewing needles 3 and 3 remain stopped at the top of the vertical movement. A space is formed between the sewing needles 3 and 3 and the upper feed leg 92 and the presser foot 82.

次に、制御手段は、図15,13に示すように、電磁アクチュエータ90を駆動して、引寄せ部材131,131を往復動させる。電磁アクチュエータ90を駆動して、駆動軸91を突出させると、連結部材145に連結された第1のリンク部材141の第1のアーム143が反時計方向に回動し、同様に第1のリンク部材141の第2のアーム144も反時計方向に回動して、第2のアーム144に連結された第2のリンク部材142を介してスライド片121がガイド長孔115に沿ってミシン針3,3(作業者)側に向かって下降する。スライド片121に設けられた引寄せ部材131,131の係止爪(糸捕捉部)132,132も下降する。   Next, the control means drives the electromagnetic actuator 90 to reciprocate the attracting members 131 and 131 as shown in FIGS. When the electromagnetic actuator 90 is driven to project the drive shaft 91, the first arm 143 of the first link member 141 connected to the connecting member 145 rotates counterclockwise, and similarly the first link. The second arm 144 of the member 141 also rotates counterclockwise, and the slide piece 121 moves along the guide long hole 115 through the second link member 142 connected to the second arm 144. , 3 descends toward the (worker) side. The locking claws (thread catching portions) 132 and 132 of the attracting members 131 and 131 provided on the slide piece 121 are also lowered.

引寄せ部材131,131の先端に設けられた係止爪(糸捕捉部)132,132は、押さえ足82の挿通孔86,86及び上送り足92の挿通孔96,96を挿通して、ミシン針3,3の下端と上送り足92及び押さえ足82との間のスペースをA方向(作業者方向)に通過(往動)する。引寄せ部材131,131の係止爪(糸捕捉部)132,132は、先端が傾斜しているので、針糸4,4を捕捉することはない。   Locking claws (thread catching portions) 132 and 132 provided at the leading ends of the attracting members 131 and 131 are inserted through the insertion holes 86 and 86 of the presser foot 82 and the insertion holes 96 and 96 of the upper feed foot 92, respectively. The space between the lower ends of the sewing needles 3 and 3 and the upper feed foot 92 and the presser foot 82 passes (forwards) in the A direction (operator direction). Since the locking claws (thread catching portions) 132, 132 of the attracting members 131, 131 are inclined at the tips, the needle threads 4, 4 are not caught.

次に、制御手段が電磁アクチュエータ90を駆動して、駆動軸91を引き戻すと、連結部材145に連結された第1のリンク部材141の第1のアーム143が時計方向に回動し、同様に第1のリンク部材141の第2のアーム144も時計方向に回動して、第2のアーム144に連結された第2のリンク部材142を介してスライド片121がガイド長孔115に沿ってミシン針3,3から離れるB方向(作業者から離れる方向)に向かって上昇する。スライド片121に設けられた引き寄せ部材131,131の係止爪(糸捕捉部)132,132も上昇する。   Next, when the control means drives the electromagnetic actuator 90 and pulls back the drive shaft 91, the first arm 143 of the first link member 141 connected to the connecting member 145 rotates in the clockwise direction. The second arm 144 of the first link member 141 also rotates in the clockwise direction, and the slide piece 121 moves along the guide long hole 115 via the second link member 142 connected to the second arm 144. Ascending in the B direction (direction away from the operator) away from the sewing needles 3 and 3. The locking claws (thread catching portions) 132 and 132 of the drawing members 131 and 131 provided on the slide piece 121 are also raised.

引寄せ部材131,131の係止爪(糸捕捉部)132,132は、後端が直角となっているので、図15に示すように、B方向(作業者から離れる方向)に引き戻される(復動する)時に、針糸4,4を捕捉して針糸4,4の切断端部を被縫製物Mの上方に引き抜いて保持する。このように、引寄せ部材131,131は、ガイド長穴115に沿って前方へ下降移動し、針糸4,4を捕捉してガイド長穴115に沿って後方へ上昇移動するので、針糸4,4を被縫製物Mから上方へ引き抜くようになり、針糸4,4を被縫製物Mから確実に引き出せる。糸払い装置101は、アクチュエータ90の動作を第1のリンク部材141と第2のリンク部材142を介して引寄せ部材131に伝達するので、駆動軸91の短い往復動作で引寄せ部材131の長い往復動作を確実に行わせることができる。   Since the rear ends of the locking claws (thread catching portions) 132, 132 of the attracting members 131, 131 are at right angles, they are pulled back in the B direction (direction away from the operator) as shown in FIG. At the time of returning), the needle threads 4 and 4 are captured and the cut ends of the needle threads 4 and 4 are pulled out above the sewing product M and held. As described above, the attracting members 131 and 131 move downward along the guide elongated hole 115, capture the needle threads 4 and 4, and move upward along the elongated guide hole 115, so that the needle thread 4 and 4 are pulled upward from the sewing product M, and the needle threads 4 and 4 can be reliably pulled out of the sewing product M. Since the yarn wiper 101 transmits the operation of the actuator 90 to the drawing member 131 via the first link member 141 and the second link member 142, the drawing member 131 is long by the short reciprocation of the drive shaft 91. The reciprocating operation can be performed reliably.

ミシンの糸払い装置101は、作業者からみて、押さえ軸2の後方(ミシンの針棒5の反対側)に取り付けられ、ワイパー片に相当する引寄せ部材131が押さえ足82及び上送り足92に形成された挿通孔86,96内を挿通して、針棒5と押さえ軸2を結ぶ略直線方向(送り方向、前後方向)で往復動作を行うので、作業者の縫製作業の障害となり難い。しかも引寄せ部材131及び駆動機構(アクチュエータ90)が被縫製物Mに接触しないので、被縫製物Mを傷つけてしまう虞がない。即ち、引寄せ部材131は、押さえ足82の挿通孔86及び上送り足92の挿通孔96内で前後方向の往復動作を行うので、作業者及び被縫製物Mに接触する虞が極めて少ない。   The thread wiping device 101 of the sewing machine is attached to the rear side of the presser shaft 2 (opposite side of the needle bar 5 of the sewing machine) as viewed from the operator, and the pulling member 131 corresponding to the wiper piece includes the presser foot 82 and the upper feed foot 92. Are inserted into the insertion holes 86 and 96 formed in the upper and lower sides, and the reciprocating operation is performed in a substantially linear direction (feeding direction, front-rear direction) connecting the needle bar 5 and the pressing shaft 2, so that it is difficult for the operator to interfere with the sewing work. . Moreover, since the pulling member 131 and the drive mechanism (actuator 90) do not contact the sewing product M, there is no possibility that the sewing product M will be damaged. That is, the pulling member 131 reciprocates in the front-rear direction in the insertion hole 86 of the presser foot 82 and the insertion hole 96 of the upper feed leg 92, so that there is very little possibility of contact with the operator and the sewing product M.

さらに、ミシンの糸払い装置101は、引寄せ部材131,131の糸捕捉部(係止爪)132,132がミシン針3,3の前方から後方、即ち作業者から離れる方向に向かって、針糸4,4を払う構成なので、引寄せ部材131,131自体及び引寄せ部材131,131によって払われた針糸4,4の端部が作業者、被縫製物Mに接触する可能性がなく、作業に支障が出ることがない。特に、引寄せ部材131の糸捕捉部(係止爪)132,132が、図15に示すように、針糸4,4の残端部を押さえ足82の挿通孔86,86及び上送り足92の挿通孔96,96内に引き込むので、針糸4,4の残端部が作業者、被縫製物Mに接触することがない。   Further, the thread wiping device 101 of the sewing machine is configured so that the thread catching portions (locking claws) 132, 132 of the attracting members 131, 131 are moved from the front of the sewing needles 3, 3 to the rear, that is, in the direction away from the operator. Since it is the structure which pays the thread | yarns 4 and 4, there is no possibility that the edge part of the needle members 4 and 4 paid by the attracting members 131 and 131 itself and the attracting members 131 and 131 will contact an operator and the sewing product M. , Work will not be hindered. In particular, as shown in FIG. 15, the thread catching portions (locking claws) 132, 132 of the attracting member 131 push the remaining ends of the needle threads 4, 4 through the insertion holes 86, 86 of the presser foot 82 and the upper feed foot. Since it is pulled into the 92 insertion holes 96, 96, the remaining ends of the needle threads 4, 4 do not come into contact with the operator and the sewing product M.

上記糸払い装置101は、一対の引寄せ部材131,131を挿通させる挿通部を押さえ足82の一対の挿通孔86,86及び上送り足92の一対の挿通孔96,96で説明したが、図11,12に示すように、糸払い装置51の押さえ足52と上送り足62と同様に、一つの挿通溝で形成しても良い。また、上記糸払い装置101は、二本針ミシンで説明したが、二本針ミシンに限定されるものではなく、一本針ミシンでも利用することができる。さらに、上記実施の形態では、釜を備えた本縫いミシンに取り付けられる糸払い装置で説明を行ったが、ルーパーによって縫い目を形成する環縫いミシンにも本願発明に係る糸払い装置を取り付けることができることは勿論である。   The thread wiper 101 has been described with the pair of insertion holes 86 and 86 of the presser foot 82 and the pair of insertion holes 96 and 96 of the upper feed foot 92 as the insertion portion through which the pair of drawing members 131 and 131 are inserted. As shown in FIGS. 11 and 12, similarly to the presser foot 52 and the upper feed foot 62 of the yarn wiper device 51, it may be formed by one insertion groove. Moreover, although the said thread wiping apparatus 101 demonstrated with the two-needle sewing machine, it is not limited to a two-needle sewing machine, It can utilize also with a single-needle sewing machine. Furthermore, in the above-described embodiment, the description has been made with respect to the thread wiping device attached to the lockstitch sewing machine provided with the hook. Of course you can.

本願発明は、糸切断装置を備えたミシンに利用可能である。   The present invention is applicable to a sewing machine equipped with a yarn cutting device.
