It reciprocates in the left-right direction between the right needle 16a, the middle needle 16b and the left needle 16c up to the range of FIG.
前記アーム１９は、アームヘッド７に支持されるブラケット２５に振り軸８と平行をなして回転可能に軸支される軸２７に固着のレバー２８とリンク３０により連結され、振り軸８の揺動がアーム１９に伝えられ、リンク３０及びレバー２８を介して軸２７を揺動させるようになっている。振り軸８の揺動を軸２７に伝える機構も前記機構に代えて他の任意の伝動機構を用いることができる。 The arm 19 is connected to a bracket 25 supported by the arm head 7 by a lever 28 and a link 30 fixed to a shaft 27 that is rotatably supported in parallel with the swing shaft 8, and swings the swing shaft 8. Is transmitted to the arm 19, and the shaft 27 is swung via the link 30 and the lever 28. As the mechanism for transmitting the swing of the swing shaft 8 to the shaft 27, any other transmission mechanism can be used instead of the mechanism.
軸２７には、目孔３３を備えた糸ガイド３２が取付けられると共に台２６が取り付けられ、該台２６には、湾曲したキャリヤー針３４の垂直な取付部が差込んで取付けられている。そしてこれら糸ガイド３２とキャリヤー針３４がスプレッダー上において前記軸２７の周りを揺動し、糸ガイド３２の目孔３３が右針１６ａの右斜め手前の図５の位置より右針１６ａの右側の図２の位置との間の範囲で、またキャリヤー針３４先端の目孔３５が右針１６ａ手前の図５の位置より右針１６ａと、その隣の中針１６ｂの間に進入した図２の位置との間の範囲で進退するようになっている。図１において、３７はミシンアームに取付けられる飾り糸案内である。 A thread guide 32 having a hole 33 is attached to the shaft 27 and a base 26 is attached to the shaft 27, and a vertical attachment portion of a curved carrier needle 34 is inserted into the base 26. Then, the thread guide 32 and the carrier needle 34 swing around the shaft 27 on the spreader, and the eye 33 of the thread guide 32 is located on the right side of the right needle 16a from the position in FIG. 5 just before the right needle 16a. 2, the eye hole 35 at the tip of the carrier needle 34 enters between the right needle 16a and the adjacent middle needle 16b from the position of FIG. 5 before the right needle 16a. It is designed to move forward and backward within the range between the positions. In FIG. 1, reference numeral 37 denotes a decorative thread guide attached to the sewing machine arm.
前述する糸ガイド３２の目孔３３及びキャリヤー針３４の目孔３５は、図示する例では丸孔となっているが、長円形の長孔であってもよいし、図１３に示すような溝状の目孔であってもよい。また、これら目孔は、図示する例では上下に貫通して形成されているが、水平方向に貫通する形態でもよい。 The above-described eye holes 33 of the thread guide 32 and the eye holes 35 of the carrier needle 34 are round holes in the illustrated example, but may be oval long holes or grooves as shown in FIG. It may be a shaped eye hole. In addition, these eye holes are formed so as to penetrate vertically in the example shown in the figure, but they may be penetrated in the horizontal direction.
以上のように糸ガイド３２とキャリヤー針３４は前後方向に揺動して進退し、前記揺動軸４、リンク機構１３、振り軸８、アーム１９、リンク３０、レバー２８、軸２７、台２６等が糸ガイド３２とキャリヤー針３４を進退させる作動機構を構成するが、前記スプレッダー２１を左右に振る往復動機構、すなわち前記揺動軸４、リンク機構１３、振り軸８、アーム１８よりなる機構とは、揺動軸４から振り軸８に至る機構までを共通とし、振り軸８を共通の揺動軸として糸ガイド３２及びキャリヤー針３４の軸２７を中心として旋回する往復動が行われる。 As described above, the thread guide 32 and the carrier needle 34 are swung back and forth in the front-rear direction to advance and retreat, and the swing shaft 4, the link mechanism 13, the swing shaft 8, the arm 19, the link 30, the lever 28, the shaft 27, and the base 26. Constitute an operating mechanism for moving the yarn guide 32 and the carrier needle 34 back and forth, but a reciprocating mechanism for swinging the spreader 21 left and right, that is, a mechanism comprising the swing shaft 4, the link mechanism 13, the swing shaft 8 and the arm 18. Means that the mechanism from the swinging shaft 4 to the swinging shaft 8 is common, and reciprocating motion is performed in which the swinging shaft 8 is a common swinging shaft and swivels around the shaft 27 of the yarn guide 32 and the carrier needle 34.
糸ガイド３２とキャリヤー針３４を往復動させる機構としては、前記実施形態では前述するような揺動機構を用いているが、往復直線運動させる機構を採用することも可能であり、また糸ガイド３２とキャリヤー針３４の揺動機構に関しても、前記実施形態の揺動機構に限定されることなく他の既知の揺動機構を用いることができる。こうした既知の揺動機構としては、例えば前記特許文献１に開示されるようなキャリヤー針の作動機構を例示することができる。 As the mechanism for reciprocating the yarn guide 32 and the carrier needle 34, the swing mechanism as described above is used in the above embodiment, but a mechanism for reciprocating linear movement can also be adopted. The swing mechanism of the carrier needle 34 is not limited to the swing mechanism of the above embodiment, and other known swing mechanisms can be used. As such a known rocking mechanism, for example, an operating mechanism of a carrier needle as disclosed in Patent Document 1 can be exemplified.
前記実施形態ではまた、糸ガイド３２とキャリヤー針３４は共に軸２７の周りを揺動するように構成されているが、主軸に連動して作動する別々の独立した作動機構により往復動させるようにすることもできる。これにより糸ガイド３２とキャリヤー針３４を最適なタイミングと最適な軌跡で運動させることが可能となる。 In the above-described embodiment, the thread guide 32 and the carrier needle 34 are both configured to swing around the shaft 27. However, the thread guide 32 and the carrier needle 34 are reciprocated by separate independent operating mechanisms that operate in conjunction with the main shaft. You can also As a result, the thread guide 32 and the carrier needle 34 can be moved with the optimum timing and the optimum locus.
アームヘッド下の針板３６は、図示しないミシンベッド上面に取付けられ、針板下のベッド内には、図８〜図１２に示されるルーパ３８が配置されている。このルーパ３８にはルーパ糸３９が通され、よく知られるように上針１６ａ、１６ｂ、１６ｃの上下動と同期して布送りと直交する方向の左右動と、布送り方向の前後動よりなる楕円運動を行い、上針１６ａ、１６ｂ、１６ｃと協働して後述の針糸４１ａ、４１ｂ、４１ｃとルーパ糸３９による縫い目形成を行うようになっている。 The needle plate 36 under the arm head is attached to the upper surface of a sewing machine bed (not shown), and a looper 38 shown in FIGS. 8 to 12 is disposed in the bed under the needle plate. A looper thread 39 is passed through the looper 38. As is well known, the looper thread 39 includes a left-right movement in a direction orthogonal to the cloth feed in synchronization with a vertical movement of the upper needles 16a, 16b, 16c, and a back-and-forth movement in the cloth feed direction. Ellipse motion is performed, and seams are formed by later-described needle threads 41a, 41b, 41c and looper thread 39 in cooperation with upper needles 16a, 16b, 16c.
偏平縫いミシンは以上のように構成され、布に偏平縫いを行うときには、先ず各針１６ａ、１６ｂ、１６ｃにそれぞれ針糸４１ａ、４１ｂ、４１ｃを通し、糸ガイド３２の目孔３３に第１の上飾り糸４３ａを、キャリヤー針３４の目孔３５に第２の上飾り糸３９ｂをそれぞれ通すと共に、ルーパ３８にルーパ糸３９を通しておいて布への縫製を開始する。 The flat stitch sewing machine is configured as described above. When flat stitching is performed on a cloth, first, the needle threads 41a, 41b, and 41c are passed through the needles 16a, 16b, and 16c, respectively, and the first thread 33 is inserted into the eye hole 33 of the thread guide 32. The upper decorative thread 43a is passed through the eye holes 35 of the carrier needle 34, and the second upper decorative thread 39b is passed through the looper 38, and the looper thread 39 is passed through the looper 38 to start sewing on the cloth.
図２〜図１２は、縫製途上での縫い目形成過程を示すもので、いま上針１６ａ、１６ｂ、１６ｃが布上に上昇して上死点に位置し、かつスプレッダー２１が上針１６ａ、１６ｂ、１６ｃの手前を前進して第１及び第２の糸掛部２２及び２３に第１及び第２の上飾り糸４３ａ及び４３ｂを引掛け、これら各上飾り糸４３ａ、４３ｂを牽引して左死点付近に位置し、また糸ガイド３２が前進して上針のうち、右針１６ａにより形成される一列目の針糸ステッチから延び、前記第１の糸掛部２２に掛けられた第１の飾り糸４３ａを通す目孔３３が右針１６ａの右側の前進端近くに位置し、かつキャリヤー針３４が前進して、中針１６ｂにより形成される二列目の針糸ステッチから延び、前記第２の糸掛部２３に掛けられた第２の上飾り糸４３ｂを通す目孔３５が右針１６ａと中針１６bの間を通過した前進端近くの位置にあるとする（図２）。 2 to 12 show a process of forming a seam in the course of sewing. Now, the upper needles 16a, 16b and 16c are raised on the cloth and positioned at the top dead center, and the spreader 21 is located at the upper needles 16a and 16b. , 16c forward, hook the first and second upper thread 43a and 43b on the first and second thread hooks 22 and 23, and pull these upper thread 43a and 43b to the left. The first thread thread guide 32 is located near the dead center and extends from the first thread thread stitch formed by the right needle 16a of the upper needle by the advancement of the thread guide 32, and is hung on the first thread hook portion 22. The eye hole 33 through which the decorative thread 43a is passed is positioned near the forward end of the right side of the right needle 16a, and the carrier needle 34 is advanced to extend from the second row of needle thread stitches formed by the middle needle 16b. Through the second upper decoration thread 43b hung on the second thread hook 23 Needle eye 35 and in the advanced end position near the passing between the right needle 16a and Chuhari 16b (FIG. 2).
この状態より上針１６ａ、１６ｂ、１６ｃが降下し始めると、スプレッダー２１が前進端の左死点に、かつ糸ガイド３２及びキャリヤー針３４が前進端に達する。上針１６ａ、１６ｂ、１６ｃが更に降下すると、スプレッダー２１が左死点から右方に後退し始めると共に、糸ガイド３２とキャリヤー針３４が手前側に向けて旋回して後退し始め、かつ左針１６ｃが中針１６ｂにより形成される二列目の針糸ステッチから伸び、かつ前記第２の糸掛部２３に掛けられる第２の上飾り糸４３ｂとスプレッダー２１との間に降下する（図８）。 When the upper needles 16a, 16b, 16c begin to descend from this state, the spreader 21 reaches the left dead center of the forward end, and the thread guide 32 and the carrier needle 34 reach the forward end. When the upper needles 16a, 16b, and 16c are further lowered, the spreader 21 starts to retreat to the right from the left dead center, and the thread guide 32 and the carrier needle 34 turn to the front side and begin to retreat, and the left needle 16c extends from the needle thread stitch of the second row formed by the middle needle 16b, and descends between the second upper decoration thread 43b and the spreader 21 that is hung on the second thread hook portion 23 (FIG. 8). ).
上針１６ａ、１６ｂ、１６ｃが更に降下すると、スプレッダー２１が各糸掛部２２及び２３に上飾り糸４３ａ、４３ｂをかけたまま図の右方に後退を続けると共に、糸ガイド３２とキャリヤー針３４が手前側に後退を続け、かつ左針１６ｃが布ｗを刺し通し、更に、中針１６ｂが第２の糸掛部２３に掛けられ、かつキャリヤー針３４の目孔３５に至る第２の上飾り糸４３ｂとスプレッダー２１との間に降下し、また右針１６ｂにより形成される一列目の針糸ステッチから伸び、前記第１の糸掛部２２に掛けられた第１の上飾り糸４３ａとスプレッダー２１との間に降下する（図３）。 When the upper needles 16a, 16b, and 16c are further lowered, the spreader 21 continues to retreat to the right in the drawing while the upper decorative threads 43a and 43b are being applied to the respective thread hooks 22 and 23, and the thread guide 32 and the carrier needle 34. Continues to retreat to the near side, the left needle 16c pierces the cloth w, the middle needle 16b is hooked on the second thread hook 23, and the second upper surface reaching the eye hole 35 of the carrier needle 34 is A first upper decorative thread 43a that descends between the decorative thread 43b and the spreader 21 and extends from the first-line needle thread stitch formed by the right needle 16b and is hung on the first thread hooking portion 22; It descends to the spreader 21 (FIG. 3).
上針１６ａ、１６ｂ、１６ｃが更に降下し、スプレッダー２１が図の右方に、糸ガイド３２とキャリヤー針３４が更に後退を続けると、第２の上飾り糸４３ｂは左針１６ｃの周りを周回した状態でスプレッダー２１の後退により第２の糸掛部２３より外れて弛むが、キャリヤー針３４が手前側に旋回して後退することにより引張られて弛みを吸収され、左針１６ｃに掛けられた状態で中針１６ｂを経て手前側に引出される（図９）。 When the upper needles 16a, 16b, and 16c are further lowered, the spreader 21 is moved to the right in the drawing, and the thread guide 32 and the carrier needle 34 are further retracted, the second upper decoration thread 43b goes around the left needle 16c. In this state, the spreader 21 retracts and loosens from the second thread hooking portion 23, but the carrier needle 34 is pulled back and pulled back to absorb the slack, and is hung on the left needle 16c. In this state, it is pulled out through the middle needle 16b (FIG. 9).
一方、第１の上飾り糸４３ａは中針１６ｂの周りを周回した状態で、スプレッダー２１の後退により第１の糸掛部２２より外れて弛むが、糸ガイド３２が手前側に旋回して後退することにより引張られ、弛みを吸収される。同時に右針１６ａが、中針１６ｂを周回し糸ガイド３２の目孔３３に至る第１の上飾り糸４３ａとスプレッダー２１の間に降下する（図４）。 On the other hand, the first upper decoration thread 43a circulates around the middle needle 16b and is loosened from the first thread hooking portion 22 due to the retraction of the spreader 21, but the thread guide 32 pivots backward to retract. By doing so, it is pulled and the slack is absorbed. At the same time, the right needle 16a descends between the first upper decoration thread 43a and the spreader 21 that goes around the middle needle 16b and reaches the eye hole 33 of the thread guide 32 (FIG. 4).
上針１６ａ、１６ｂ、１６ｃが下死点に達すると、スプレッダー２１は後退端の右死点に近付き、かつキャリヤー針３４及び糸ガイド３２も手前側に旋回して後退端に近付く。第２の上飾り糸４３ｂは左針１６ｃに掛けられ、スプレッダー２１上を横断して旋回するキャリヤー針３４の手前側への後退により、スプレッダー上に乗り掛って引き締められる一方、第１の上飾り糸４３ａは中針１６ｂに掛けられ、スプレッダー２１より外れた状態で糸ガイド３２の手前側への後退により引き締められる（図１０）。 When the upper needles 16a, 16b, and 16c reach the bottom dead center, the spreader 21 approaches the right dead center at the retracted end, and the carrier needle 34 and the thread guide 32 also pivot to the near side and approach the retracted end. The second upper decoration thread 43b is hung on the left needle 16c, and is pulled over the spreader by the backward movement of the carrier needle 34 that swivels across the spreader 21, while the first upper decoration thread 43b is tightened. The thread 43a is hung on the middle needle 16b, and is tightened by retreating the thread guide 32 toward the front side in a state of being detached from the spreader 21 (FIG. 10).
上針１６ａ、１６ｂ、１６ｃが下死点より上昇し始めると、スプレッダー２１が右死点に、かつキャリヤー針３４及び糸ガイド３２が手前側の後退端に達する（図５）。これにより第２の上飾り糸４３ｂはスプレッダー２１に乗り掛かったまま更に手前側に引出され、また第１の上飾り糸４３ａも右針１６ａにより形成される一列目の針糸ステッチから手前側に引出される（図１１）。 When the upper needles 16a, 16b, and 16c start to rise from the bottom dead center, the spreader 21 reaches the right dead center, and the carrier needle 34 and the thread guide 32 reach the rearward end on the near side (FIG. 5). As a result, the second upper decorative thread 43b is pulled out further toward the front side while riding on the spreader 21, and the first upper decorative thread 43a is also moved forward from the first-line needle thread stitch formed by the right needle 16a. It is pulled out (FIG. 11).
上針１６ａ、１６ｂ、１６ｃが更に上昇すると、スプレッダー２１が各上針１６ａ、１６ｂ、１６ｃの手前を左方に前進すると共に、キャリヤー針３４及び糸ガイド３２が後退端より針側に前進する（図６）。そして前進途上において、スプレッダー２１に乗り掛かる第２の上飾り糸４３ｂは第２の糸掛部２３に掛けられると共に、右針１６ａにより形成される一列目の針糸ステッチから糸ガイド３２の目孔３３に至る第１の上飾り糸４３ａがスプレッダー２１の第１の糸掛部２２に捕捉される（図１２）。そして布ｗが一縫い目分送られると共に、キャリヤー針３４及び糸ガイド３２が前進端に達する。 When the upper needles 16a, 16b, and 16c are further raised, the spreader 21 moves forward in front of the upper needles 16a, 16b, and 16c, and the carrier needle 34 and the thread guide 32 move forward from the retracted end toward the needle side ( FIG. 6). In the course of the forward movement, the second upper decoration thread 43b that hangs on the spreader 21 is hooked on the second thread hook 23, and the stitches of the thread guide 32 are formed from the first-line needle thread stitch formed by the right needle 16a. The first upper decoration thread 43a reaching 33 is captured by the first thread hook portion 22 of the spreader 21 (FIG. 12). The fabric w is fed by one stitch, and the carrier needle 34 and the thread guide 32 reach the forward end.
以上のようにして糸飾り糸４３ａ、４３ｂの縫込みが行われる。
前記実施形態では、糸ガイド３２は前後方向に揺動して第１の上飾り糸４３ａの糸締めを行うようになっているが、スプレッダー２１によって引き出される第１の上飾り糸４３ａの引出し量は第２の上飾り糸４３ｂの引出し量より少なく、糸ガイド３２を固定していても縫い目形成に特に支障はないが、きれいな理想的な縫い目を形成するためには、前記実施形態に示されるように、糸ガイド３２は前後方向に揺動するのが望ましい。
As described above, the thread decoration threads 43a and 43b are sewn.
In the above-described embodiment, the yarn guide 32 swings in the front-rear direction to fasten the first upper decoration thread 43a. However, the amount of the first upper decoration thread 43a drawn by the spreader 21 is pulled out. Is smaller than the pull-out amount of the second upper decoration thread 43b, and there is no particular problem in the formation of the seam even if the thread guide 32 is fixed, but in order to form a clean ideal seam, it is shown in the above embodiment. Thus, it is desirable that the yarn guide 32 swings in the front-rear direction.
以上のようにして上飾り糸４３ａが右針１６ａと中針１６bにより形成される一列目と二列目の針糸ステッチに縫込まれると共に、上飾り糸４３ｂが左針１６cと中針１６bにより形成される三列目と二列目の針糸ステッチに縫込まれ、上飾り糸４３ａと上飾り糸４３ｂが縫い目の左右に分かれ、重なることがない。したがって上飾り糸４３ａと上飾り糸４３ｂに異色の糸を用いた場合、色むらを生ずることなく縫い目の左右に色分けされる。 As described above, the upper decoration thread 43a is sewn into the first and second needle thread stitches formed by the right needle 16a and the middle needle 16b, and the upper decoration thread 43b is formed by the left needle 16c and the middle needle 16b. The upper and lower threads 43a and 43b are sewn into the left and right stitches so that they do not overlap. Therefore, when different colored threads are used for the upper decorative thread 43a and the upper decorative thread 43b, the right and left stitches are color-coded without causing uneven color.
上針１６ａ、１６ｂ、１６ｃに担持される針糸４１ａ、４１ｂ、４１ｃとルーパ３８に担持されるルーパ糸３９による縫い目形成は、よく知られた周知の方法によって行われ、この縫い目形成自体は本発明の特徴ではないので詳細な説明は省略する。
図１４は、前述するようにして上飾り糸４３ａ、４３ｂが縫込まれた偏平縫い目構造を示す。
The formation of the seam by the needle threads 41a, 41b, 41c carried by the upper needles 16a, 16b, 16c and the looper thread 39 carried by the looper 38 is performed by a well-known and well-known method. Since it is not a feature of the invention, a detailed description is omitted.
FIG. 14 shows a flat stitch structure in which the upper decorative threads 43a and 43b are sewn as described above.
偏平縫いミシンには、スプレッダー２１やルーパ３８が前記実施形態の偏平縫いミシンとは逆に左から右方向に往復動し、構造が前記実施形態の偏平縫いミシンと左右対称形をなす左ミシンと称される偏平縫いミシンもある。本発明はこうした左ミシンの偏平縫いミシンにも適用可能で、この左ミシンの偏平縫いミシンではしたがって、前記実施形態の偏平縫いミシンとは逆に一列目の針糸ステッチは左針により、二列目の針糸ステッチな中針により、また三列目の針糸ステッチは右針により形成される。 In the flat stitching machine, the spreader 21 and the looper 38 reciprocate from left to right in the opposite direction to the flat stitching sewing machine of the above-described embodiment, and the left sewing machine whose structure is symmetrical to the flat stitching sewing machine of the above-described embodiment. There is also a so-called flat stitch sewing machine. The present invention can also be applied to a flat stitch sewing machine of such a left sewing machine. Therefore, in the flat stitch sewing machine of the left sewing machine, the needle thread stitch of the first row is opposite to the flat stitch sewing machine of the above-described embodiment by the left needle. The needle thread stitch is formed by the middle needle, and the needle thread stitch in the third row is formed by the right needle.
