Description

本発明は、テープやコードなどの紐状の刺繍材を針元位置に対して縫い進み方向の左右に千鳥振りさせつつ供給して布地などの被縫製物に縫い着ける刺繍ミシンにおいて、針棒の上下動に連動して上下動し、被縫製物を押え付ける布押え体の構造に関する。   The present invention relates to an embroidery sewing machine in which a string-like embroidery material such as a tape or a cord is supplied while being staggered to the left and right in the sewing advance direction with respect to the needle base position, and sewn onto a sewing object such as a cloth. The present invention relates to a structure of a presser foot that moves up and down in conjunction with the up and down motion and presses a sewing product.

従来、特許文献１、２に示すように、テープやコードなどの紐状の刺繍材を針元に対して千鳥振りさせながら供給して布地などの被縫製物に縫い着ける、所謂千鳥縫いが可能なミシンヘッドを備えた刺繍ミシンが知られている。この特許文献１、２に開示されているミシンヘッドは、下端部に縫針が装着されて上下に駆動される針棒と、針棒の上下動に連動して上下動する布押え体と、針棒の外周に該針棒と同心状に組み付けられ、その軸心回りの回転が自由な回転体と、この回転体に対してレバーピンによって揺動可能に取り付けられ、縫針の針元位置へ紐状の刺繍材を案内するガイドレバーとを備えて構成されている。
特開平08−299639号公報 特開2007−000501号公報 Conventionally, as shown in Patent Documents 1 and 2, so-called zigzag stitching is possible, in which string-like embroidery materials such as tapes and cords are supplied in a zigzag manner with respect to the needle base and can be sewn to a sewing object such as fabric. An embroidery sewing machine having a simple sewing head is known. The sewing head disclosed in Patent Documents 1 and 2 includes a needle bar having a sewing needle attached to the lower end thereof and driven up and down, a presser foot that moves up and down in conjunction with the vertical movement of the needle bar, and a needle It is assembled to the outer periphery of the bar concentrically with the needle bar, and it is attached to a rotating body that can freely rotate around its axis, and is swingably attached to this rotating body by a lever pin. And a guide lever for guiding the embroidery material.
Japanese Unexamined Patent Publication No. 08-299639 JP 2007-000501 A

このようなミシンヘッドを備えた刺繍ミシンでは、所定の縫いデータに基づいて被縫製物に対する縫い進み方向を算出し、この縫い進み方向に従って、レバーピンが常時縫い進み方向の前方の正面に位置するように回転体を方向制御しつつ縫い動作を行う。その際には、ガイドレバーをレバーピン回りに往復揺動させることで、刺繍材を縫針の針元に対して所定のパターンで縫い進み方向に対して左右に千鳥振りさせながら供給し、針棒を上下に駆動して本縫いにより刺繍材を被縫製物に縫い着けるようになっている。   In an embroidery sewing machine having such a sewing head, the sewing advance direction for the workpiece is calculated based on predetermined sewing data, and the lever pin is always positioned in front of the sewing advance direction in accordance with the sewing advance direction. The sewing operation is performed while the direction of the rotating body is controlled. At that time, by swinging the guide lever back and forth around the lever pin, the embroidery material is fed in a predetermined pattern with respect to the needle base of the sewing needle in a staggered direction to the left and right with respect to the sewing advance direction. The embroidery material is sewn on the sewing product by driving up and down and performing main sewing.

ところで、従来の刺繍ミシンにおいてミシンヘッドの一部を構成する布押え体は、その下端部に被縫製物を押え付ける布押え部を有しており、刺繍材を被縫製物に縫い着ける際には、この布押え部にて針落ち位置の周りの被縫製物を押え付けるようになっている。この布押え部には縫針の貫通を許容する通し孔または凹部が形成されており、また布押え部の先端は針落ち位置より長く形成されている。つまりは、針落ち位置が布押え部の先端側よりも奥側に位置するように通し孔が配置されているまたは凹部が深く形成されている。そして、上記特許文献１に開示されたミシンヘッドでは布押え体がガイドレバーと同一側に設けてあり、上記特許文献２に開示されたミシンヘッドでは布押え体がガイドレバーと対向する側に設けてある。なお、布押え体は回転体の方向制御に基づいてガイドレバーとともに回転するようになっている。   By the way, in the conventional embroidery sewing machine, the presser foot that constitutes a part of the sewing head has a presser foot portion that presses the work to be sewn at the lower end thereof, and when the embroidery material is sewn on the work to be sewn. In this fabric presser, the work to be sewn around the needle drop position is pressed down. A through hole or a recess allowing the sewing needle to pass therethrough is formed in the presser foot, and the tip of the presser foot is formed longer than the needle drop position. In other words, the through hole is arranged or the recess is formed deeply so that the needle drop position is located on the back side with respect to the distal end side of the presser foot. In the sewing head disclosed in Patent Document 1, the presser body is provided on the same side as the guide lever, and in the sewing head disclosed in Patent Document 2, the presser body is provided on the side facing the guide lever. It is. The presser foot is rotated together with the guide lever based on the direction control of the rotating body.

ここで、従来の刺繍ミシンにおいて千鳥縫いを行った際に、ガイドレバーが縫い進み方向の左側に揺動した状態を表す平面概略図を図７に示す。図７において、Ｇはガイドレバー、Ｔは紐状の刺繍材、Ｐは縫針の針落ち位置（ステッチ位置）、Ｐａは一つ前のステッチ位置である。この図より明らかなように、ガイドレバーＧの刺繍材Ｔを案内している先端部分が、実線で示す位置（針落ち位置Ｐに遠い位置）にある場合と、想像線（二点鎖線）で示す前記実線で示した位置よりも針落ち位置Ｐに近い位置にある場合とでは、想像線で示す位置にある場合の方が一つ前のステッチ位置Ｐａにより近く、実線で示す位置にある場合と比べると該一つ前のステッチ位置Ｐａを中心とする刺繍材Ｔの振り角が大きくなっている。すなわち、ガイドレバーＧの先端部分は針落ち位置Ｐに近い方が刺繍材Ｔの振り角が大きくなり、これにより刺繍材Ｔと縫針との接触を確実に防止することができ、刺繍材Ｔの千鳥縫いを安定して行えることとなる。   Here, FIG. 7 shows a schematic plan view showing a state in which the guide lever swings to the left in the sewing advance direction when staggered stitching is performed in the conventional embroidery sewing machine. In FIG. 7, G is a guide lever, T is a string-like embroidery material, P is a needle drop position (stitch position) of a sewing needle, and Pa is a previous stitch position. As is apparent from this figure, the tip of the guide lever G guiding the embroidery material T is at the position indicated by the solid line (the position far from the needle drop position P), and the imaginary line (two-dot chain line). In the case where the position is closer to the needle drop position P than the position indicated by the solid line, the case where the position is indicated by the imaginary line is closer to the previous stitch position Pa and is the position indicated by the solid line. The swing angle of the embroidery material T around the previous stitch position Pa is larger. That is, the swing angle of the embroidery material T is larger at the tip portion of the guide lever G closer to the needle drop position P, which can reliably prevent contact between the embroidery material T and the sewing needle. Staggered stitching can be performed stably.

しかしながら、上記特許文献１に開示されたミシンヘッドにおいては、布押え体がガイドレバーと同一側に設けてあるため、ガイドレバーの先端部分を針落ち位置に近づける場合にガイドレバーの先端部分が布押え体の背面と干渉しない位置までしか近づけることができない。一方、上記特許文献２に開示されたミシンヘッドにおいては、布押え体がガイドレバーに対向して設けてあるため、ガイドレバーの先端部分を上記特許文献１に開示されたミシンヘッドよりは針落ち位置に近づけることができるものの、上記したように布押え体の布押え部の先端は針落ち位置より長く形成されていることから、ガイドレバーの先端部分をその布押え部の先端と干渉しない位置までしか近づけることができない。このように、従来ではガイドレバーの先端部分をより針落ち位置に近づけようとする場合、ガイドレバーの先端を布押え体に干渉しないように針落ち位置からは少し離れた位置までしか近づけることができずに、それ以上にガイドレバーの先端部分を針落ち位置に近づけることは不可能な構造であった。   However, in the sewing machine head disclosed in Patent Document 1, since the cloth presser body is provided on the same side as the guide lever, when the tip part of the guide lever is brought close to the needle drop position, the tip part of the guide lever is the cloth head. It can only be brought close to the position where it does not interfere with the back of the presser. On the other hand, in the sewing head disclosed in Patent Document 2, since the cloth presser body is provided so as to face the guide lever, the tip portion of the guide lever is more needle drop than the sewing head disclosed in Patent Document 1. The tip of the presser foot of the presser foot is longer than the needle drop position, as described above, but the guide lever's front end does not interfere with the end of the presser foot. It can only approach. Thus, in the past, when trying to bring the tip of the guide lever closer to the needle drop position, the tip of the guide lever can be brought closer to a position slightly away from the needle drop position so as not to interfere with the presser foot. It was impossible to make the tip of the guide lever closer to the needle drop position.

また、上述したように、布押え体の布押え部には縫針の貫通を許容する通し孔または凹部が形成されているが、この通し孔または凹部は縫針から被縫製物に延びる上糸を針落ち位置の付近に案内する役目もしている。しかしながら、上記特許文献２に開示されているように、縫針の貫通を許容する部分が凹部である場合には、その前端部が開放しているために大きく刺繍枠を移動したときなどに凹部から上糸が外れてしまい、縫針から被縫製物に延びる上糸が傾斜した状態となることがある。この上糸が傾斜した状態のときに、互いに対向して設けてあるガイドレバー及び布押え体が回転制御されると、傾斜した上糸がガイドレバーや布押え体に引掛かり糸切れや針折れが発生する不具合があった。   As described above, the presser foot of the presser foot has a through hole or a recess that allows the sewing needle to pass therethrough. The through hole or the recess has a needle thread extending from the sewing needle to the sewing product. It also serves as a guide to the vicinity of the falling position. However, as disclosed in the above-mentioned Patent Document 2, when the portion allowing the needle to penetrate is a recess, the front end portion is open, so that when the embroidery frame is moved greatly, the recess is removed from the recess. The upper thread may come off, and the upper thread extending from the sewing needle to the workpiece may be inclined. When the upper lever is tilted and the guide lever and the presser foot, which are provided facing each other, are rotationally controlled, the tilted upper thread is hooked on the guide lever and the presser foot and the thread breaks or the needle breaks. There was a bug that occurred.

本発明は上述の点に鑑みてなされたもので、ガイドレバー（ガイド部）の先端部分を従来に比べて針落ち位置により近づけて刺繍材の振り角を大きくし、刺繍材の千鳥縫いをより安定して行うことができるようにした刺繍ミシンを提供しようとするものである。
また、ガイドレバー（ガイド部）の先端部分を従来に比べて針落ち位置により近づけることを可能としながらも、上糸を針落ち位置の付近に確実に案内するようにした刺繍ミシンを提供しようとするものである。 The present invention has been made in view of the above points. The tip portion of the guide lever (guide portion) is made closer to the needle drop position than in the prior art, and the swing angle of the embroidery material is increased to further stagger the embroidery material. An object of the present invention is to provide an embroidery sewing machine that can be stably performed.
In addition, an embroidery sewing machine that can guide the upper thread to the vicinity of the needle drop position while allowing the tip portion of the guide lever (guide portion) to be closer to the needle drop position than before is provided. To do.

本発明に係る布押え体は、千鳥縫いを行う刺繍ミシンの布押え体であって、下端に形成した被縫製物を押え付ける水平な布押え部の端部の上方には縫針に通された上糸を針落ち位置から離れないように案内するガイド部材を設けてなり、前記布押え部の端部を、針落ち位置に近接させるとともに、紐状の刺繍材を前記針落ち位置に案内するガイド部に対向配置したことを特徴とする。   The presser foot according to the present invention is a presser foot of an embroidery sewing machine that performs zigzag stitching, and is passed through a sewing needle above the end of a horizontal presser foot that presses a sewing product formed at the lower end. A guide member is provided for guiding the upper thread so as not to leave the needle drop position, and the end of the presser foot is brought close to the needle drop position, and the string-like embroidery material is guided to the needle drop position. It is characterized by being arranged opposite to the guide part.

本発明によれば、千鳥縫いを行う刺繍ミシンの布押え体であって、該布押え体は下端に形成した被縫製物を押え付ける水平な布押え部の端部の上方に、縫針に通された上糸を針落ち位置から離れないように案内するガイド部材を設けてなる。そして、該布押え体は布押え部の端部を針落ち位置に近接させて、紐状の刺繍材を針落ち位置に案内するガイド部に対向して配置する。このようにして、布押え部の端部を略針落ち位置に近接させるように配置すると、刺繍材を案内しているガイド部の先端部分を従来に比べて略針落ち位置に並ぶ位置にまでより近づけることが可能となり、刺繍材の振り角を大きくして刺繍材の千鳥縫いをより安定して行えるようになる。また、ガイド部材を布押え部の端部の上方に設けると、針落ち位置に近づけたガイド部の先端部分とガイド部材とが干渉することがないので、往復駆動するガイド部の先端部分を針落ち位置により近づけることを可能としながらも、回転制御されるガイド部や布押え体に引っ掛かることのないように上糸を針落ち位置の付近に確実に案内することができる。   According to the present invention, there is provided a presser foot for an embroidery sewing machine that performs zigzag stitching, and the presser foot is passed through a sewing needle above an end portion of a horizontal presser foot portion that presses a sewing product formed at the lower end. A guide member is provided for guiding the upper thread so as not to leave the needle drop position. Then, the cloth presser body is disposed so as to oppose the guide portion for guiding the string-like embroidery material to the needle drop position with the end portion of the cloth presser portion being brought close to the needle drop position. In this way, when the end of the presser foot is arranged so as to be close to the needle drop position, the leading end of the guide part that guides the embroidery material is positioned so as to line up with the needle drop position compared to the conventional case. It is possible to make the embroidery material closer, and the swing angle of the embroidery material can be increased to perform staggered stitching of the embroidery material more stably. If the guide member is provided above the end of the presser foot, the tip of the guide close to the needle drop position does not interfere with the guide member. While being able to be closer to the drop position, the upper thread can be reliably guided to the vicinity of the needle drop position so as not to be caught by the rotation-controlled guide portion or the presser foot.

本発明の好ましい一実施形態によれば、前記ガイド部材はワイヤ状であって、ガイド部先端に設けられたガイド筒の刺繍材導出口と干渉しない高さに、縫針の挿通を許容するとともに該縫針に通された上糸を通す半円部を有する形状に形成されてなり、縫針の上昇時において前記縫針から被縫製物へと繋がっている上糸を前記半円部内に位置させて、上糸を針落ち位置から離れないように案内することを特徴とする。このように、ワイヤ状のガイド部材を布押え部先端の上方にガイド部先端に設けられたガイド筒の刺繍材導出口と干渉しない高さに設けるといった簡易な構成で、ガイド部の先端部分を針落ち位置により近づけることを可能にしたうえで、上糸が回転制御されるガイド部や布押え体に引っ掛かることを防止することができる。   According to a preferred embodiment of the present invention, the guide member is wire-shaped, and allows the insertion of the sewing needle to a height that does not interfere with the embroidery material outlet of the guide tube provided at the guide tip. The upper thread that is formed in a shape having a semicircular portion through which the upper thread passed through the sewing needle is passed, and that is connected from the sewing needle to the article to be sewn when the sewing needle is raised, The yarn is guided so as not to leave the needle drop position. In this way, the tip portion of the guide portion is arranged with a simple configuration in which the wire-shaped guide member is provided above the tip of the presser foot at a height that does not interfere with the embroidery outlet of the guide tube provided at the tip of the guide portion. The needle thread can be brought closer to the needle drop position, and the upper thread can be prevented from being caught by the rotation-controlled guide portion or the presser foot.

本発明によれば、縫針に通された上糸を針落ち位置から離れないように案内するガイド部材を布押え部の端部の上方に設けてなる布押え体を、紐状の刺繍材を針落ち位置に案内するガイド部に対向するようにして配置する際に、布押え部の端部を略針落ち位置に近接させるように配置して、刺繍材を案内しているガイド部の先端部分を従来に比べて略針落ち位置に並ぶ位置にまでより近づけるようにしたことから、ガイド部が案内する刺繍材の振り角を大きくすることができ千鳥縫いをより安定して行うことができるようになる。
また、上糸を針落ち位置の付近から離れないように案内するガイド部材を布押え部先端の上方に設けるようにしたことによって、ガイド部の先端部分を従来に比べて略針落ち位置に並ぶ位置にまでより近づけることを可能にしながらも、上糸を針落ち位置の付近に確実に案内して回転制御されるガイド部や布押え体に引っ掛かることを防止することができるようになる。 According to the present invention, the cloth presser body provided with the guide member that guides the upper thread passed through the sewing needle so as not to leave the needle drop position above the end portion of the presser foot portion, the string-like embroidery material is used. The tip of the guide section that guides the embroidery material by placing the end of the presser foot close to the needle drop position when placing it facing the guide section that guides the needle drop position Since the portion is made closer to the position where it is almost aligned with the needle drop position compared to the conventional case, the swing angle of the embroidery material guided by the guide portion can be increased, and zigzag stitching can be performed more stably. It becomes like this.
In addition, by providing a guide member that guides the upper thread so as not to leave the vicinity of the needle drop position, the tip portion of the guide part is arranged approximately at the needle drop position compared to the conventional case. While making it possible to move closer to the position, the upper thread can be reliably guided to the vicinity of the needle drop position and can be prevented from being caught by the guide portion or the presser foot that is rotationally controlled.

以下、この発明の実施の形態を添付図面に従って詳細に説明する。   Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

図１及び図２は、テープやコードなどの紐状の刺繍材を針落ち位置に対して縫い進み方向の左右に千鳥振りさせつつ供給して布地などの被縫製物に縫い着ける所謂千鳥縫いが可能な刺繍ミシンのミシンヘッドＨの一実施例を示す図であり、図１はその正面図であり、図２はその一部破断側面図である。ミシンヘッドＨには、軸方向が上下方向（垂直方向）に延びるように配置された針棒２が設けられている。針棒２は、ミシン主軸１の回転によって上下方向に往復駆動されるようになっている。針棒２の下端部には縫針３が装着されている。また、針棒２の外周には支持筒４が取り付けられている。支持筒４は、ミシンヘッドＨの下部に固定された固定スリーブ５の内周面で案内されて、針棒２に対する相対的な昇降動作及び針棒２の軸心回りの回転動作が可能になっている。また、支持筒４の上端部外周には係合リング６が固定されており、係合リング６にはモータ７の駆動によって上下動する駆動アーム８が係合している。一方、支持筒４の下端には布押え支持体９が固定されている。布押え支持体９はその下端部が二股に分岐した形状に形成されており、一方の脚部の外側面にはその長手方向が上下方向に延びるキー溝９ａが形成され、他方の脚部の下端部には布押え体１０が取り付けられている。   FIG. 1 and FIG. 2 show so-called staggered stitches in which a string-like embroidery material such as a tape or a cord is fed while being staggered to the left and right in the sewing advance direction with respect to the needle drop position and sewn to a sewing object such as a fabric. FIG. 1 is a front view of a sewing head H of a possible embroidery sewing machine, FIG. 2 is a partially cutaway side view thereof, and FIG. The sewing machine head H is provided with a needle bar 2 arranged so that its axial direction extends in the vertical direction (vertical direction). The needle bar 2 is driven to reciprocate in the vertical direction by the rotation of the sewing machine main shaft 1. A sewing needle 3 is attached to the lower end of the needle bar 2. A support cylinder 4 is attached to the outer periphery of the needle bar 2. The support cylinder 4 is guided by the inner peripheral surface of the fixed sleeve 5 fixed to the lower part of the sewing head H, and can move up and down relative to the needle bar 2 and rotate around the axis of the needle bar 2. ing. An engagement ring 6 is fixed to the outer periphery of the upper end portion of the support cylinder 4, and a drive arm 8 that moves up and down by driving a motor 7 is engaged with the engagement ring 6. On the other hand, a presser foot support 9 is fixed to the lower end of the support cylinder 4. The presser foot support 9 is formed in a shape with a bifurcated lower end, and a keyway 9a extending in the vertical direction in the longitudinal direction is formed on the outer surface of one leg, and the other leg A presser foot 10 is attached to the lower end.

前記布押え体１０の下端部には、縫い時に被縫製物を押え付ける布押え部１０ａがガイドレバー２０側に突出した形状に形成してあり、この布押え部１０ａはその先端が略針落ち位置と並ぶ長さに設定してある。そして、布押え部１０ａの先端部には縫針３の挿通を許容する凹部１０ｂ（貫通部）が形成されているとともに、布押え部１０ａの先端部上方において半円部を有する形状に形成されたワイヤ状の糸ガイド１０ｃ（ガイド部材）が固定されている（詳しくは後述する図４参照）。前記糸ガイド１０ｃは、その形成する半円部が本ミシン上方から見て前記凹部１０ｂに対向する位置に配置されるよう固定される。   At the lower end of the presser foot 10, a presser foot 10 a that presses the workpiece to be sewn at the time of sewing is formed so as to protrude toward the guide lever 20, and the end of the presser foot 10 a has a substantially needle drop. It is set to the length aligned with the position. And the recessed part 10b (penetration part) which accept | permits the insertion of the sewing needle 3 is formed in the front-end | tip part of the work clamp part 10a, and it was formed in the shape which has a semicircle part above the front-end | tip part of the work clamp part 10a. A wire-shaped yarn guide 10c (guide member) is fixed (see FIG. 4 described later in detail). The yarn guide 10c is fixed so that the semicircular portion formed is arranged at a position facing the recess 10b when viewed from above the sewing machine.

固定スリーブ５の外周には、回転筒１１が取り付けられている。回転筒１１は、針棒２と同心状に取り付けられており、針棒２の軸心回りの回転動作のみが可能になっている。回転筒１１の上端部外周にはタイミングプーリ部１２が形成されており、このタイミングプーリ部１２とモータ１３の回転軸１３ａに固定された駆動プーリ１４との間にタイミングベルト１５が架けられている。これにより、モータ１３が駆動されて駆動プーリ１４が回転すると、タイミングベルト１５及びタイミングプーリ部１２を介してその回転が伝達されて、回転筒１１が回転するようになっている。一方、回転筒１１の下端には布押え支持体９のキー溝９ａに係合するキー部材１６が固定されている。したがって、布押え体１０は支持筒４の上下動に伴って上下動するとともに、回転筒１１の回転に伴って針棒２の軸心回りで回転するようになっている。   A rotating cylinder 11 is attached to the outer periphery of the fixed sleeve 5. The rotating cylinder 11 is mounted concentrically with the needle bar 2 and can only rotate around the axis of the needle bar 2. A timing pulley portion 12 is formed on the outer periphery of the upper end portion of the rotating cylinder 11, and a timing belt 15 is suspended between the timing pulley portion 12 and a driving pulley 14 fixed to the rotating shaft 13 a of the motor 13. . As a result, when the motor 13 is driven and the drive pulley 14 rotates, the rotation is transmitted through the timing belt 15 and the timing pulley portion 12 so that the rotating cylinder 11 rotates. On the other hand, a key member 16 that is engaged with the key groove 9 a of the presser foot support 9 is fixed to the lower end of the rotary cylinder 11. Accordingly, the presser foot 10 moves up and down as the support cylinder 4 moves up and down, and rotates around the axis of the needle bar 2 as the rotary cylinder 11 rotates.

回転筒１１の外周には、連動部材１７が上下動可能かつ回転可能に設置されている。連動部材１７には連結片１８が固定されており、連結片１８は回転筒１１の外周に形成された係合溝１１ａに係合している。これにより、連動部材１７は回転筒１１の回転に伴って回転筒１１と一体に回転するようになっている。また、回転筒１１にはブラケット１９を介してガイドレバー２０（ガイド部）が取り付けられている。ガイドレバー２０は、ブラケット１９の外側面に取り付けたレバーピン２１を支点として、回転筒１１に対して針棒２の軸方向の左右に揺動自在に取り付けられている。   An interlocking member 17 is installed on the outer periphery of the rotating cylinder 11 so as to be movable up and down and rotatable. A connecting piece 18 is fixed to the interlocking member 17, and the connecting piece 18 is engaged with an engaging groove 11 a formed on the outer periphery of the rotating cylinder 11. As a result, the interlocking member 17 rotates integrally with the rotating cylinder 11 as the rotating cylinder 11 rotates. In addition, a guide lever 20 (guide portion) is attached to the rotary cylinder 11 via a bracket 19. The guide lever 20 is swingably attached to the left and right in the axial direction of the needle bar 2 with respect to the rotary cylinder 11 with a lever pin 21 attached to the outer surface of the bracket 19 as a fulcrum.

ガイドレバー２０は、レバーピン２１の位置から側方に延びる一方の腕部２２ａと下方に延びる他方の腕部２２ｂとを備えて略Ｌ字型に形成されたベース部材２２と、ベース部材２２の腕部２２ｂの下端に連結されたガイドアーム２３とを備えて構成されている。ガイドアーム２３の下端には、紐状の刺繍材Ｔを縫針３の針落ち位置（針元位置）へ供給するためのガイド筒２４が取り付けられている。ガイド筒２４の下端部は、刺繍材Ｔが導出される刺繍材導出口２４ａになっている。このガイド筒２４が布押え体１０と対向するようにして、ガイドレバー２０の配置位置が設定されている。そして、前述のように布押え体１０の布押え部１０ａの先端は略針落ち位置と並ぶ長さに設定してあり、ガイド筒２４はその刺繍材導出口２４ａを可能な限り針落ち位置に近づけて固定してある。なお、布押え部１０ａの先端の上方に糸ガイド１０ｃによって形成される半円部は、後述するようにして千鳥縫い時に左右方向（水平方向）に往復揺動されるガイド筒２４の刺繍材導出口２４ａと干渉しない高さ（刺繍材導出口２４ａの往復動作を妨げない高さ）に設定されている。   The guide lever 20 includes a base member 22 having one arm portion 22a extending laterally from the position of the lever pin 21 and the other arm portion 22b extending downward, and an arm of the base member 22. The guide arm 23 is connected to the lower end of the portion 22b. A guide cylinder 24 for supplying the string-like embroidery material T to the needle drop position (needle base position) of the sewing needle 3 is attached to the lower end of the guide arm 23. The lower end of the guide tube 24 is an embroidery material outlet 24a through which the embroidery material T is derived. The arrangement position of the guide lever 20 is set so that the guide cylinder 24 faces the presser body 10. As described above, the tip of the presser foot 10a of the presser foot 10 is set to a length that is substantially aligned with the needle drop position, and the guide cylinder 24 has its embroidery outlet 24a as close to the needle drop position as possible. Close and fixed. The semicircular part formed by the thread guide 10c above the tip of the presser foot part 10a is guided by the embroidery material of the guide cylinder 24 that is reciprocally swung in the horizontal direction (horizontal direction) during zigzag stitching as will be described later. The height is set so as not to interfere with the outlet 24a (the height that does not hinder the reciprocating operation of the embroidery material outlet 24a).

一方、ベース部材２２の腕部２２ａの先端にはコロ２５が取り付けられており、コロ２５は連結片１８の連係溝１８ａに係合してある。また、回転筒１１の外周にはボビンブラケット２６が固定されており、このボビンブラケット２６には紐状の刺繍材Ｔを巻回したボビン２７が回転自在に支持されている。   On the other hand, a roller 25 is attached to the tip of the arm portion 22 a of the base member 22, and the roller 25 is engaged with the connecting groove 18 a of the connecting piece 18. A bobbin bracket 26 is fixed to the outer periphery of the rotating cylinder 11, and a bobbin 27 around which a string-like embroidery material T is wound is rotatably supported on the bobbin bracket 26.

針棒２に隣接する位置には、図１に示すように、その軸方向が上下方向（垂直方向）に延びるように配置されたガイド軸２８が配置されている。ガイド軸２８には昇降部材２９が取り付けられている。昇降部材２９は、図示しない駆動伝達機構を介して千鳥振りモータ３０の回転による駆動力が伝達されることで、ガイド軸２８で案内されながらその軸方向に沿って上下動（昇降移動）するようになっている。昇降部材２９には針棒２に向かって略水平に突出するフォーク部２９ａが形成されており、このフォーク部２９ａが連動部材１７の外周に形成された溝部１７ａに係合している。したがって、昇降部材２９の上下動によって連動部材１７及び連結片１８が上下動し、連結片１８の上下動が連係溝１８ａ及びコロ２５を介してガイドレバー２０の揺動に変換される。こうして、ガイドレバー２０の下端部に固定されたガイド筒２４が、千鳥振りモータ３０からガイドアーム２３に至る揺動機構の働きにより、レバーピン２１を支点として縫い進み方向に対して左右に直線的に往復揺動するようになっている。   As shown in FIG. 1, a guide shaft 28 is disposed at a position adjacent to the needle bar 2 so that its axial direction extends in the vertical direction (vertical direction). An elevating member 29 is attached to the guide shaft 28. The elevating member 29 is moved up and down (moved up and down) along the axial direction while being guided by the guide shaft 28 by transmitting a driving force generated by the rotation of the staggered swing motor 30 via a drive transmission mechanism (not shown). It has become. The elevating member 29 is formed with a fork portion 29 a that protrudes substantially horizontally toward the needle bar 2, and this fork portion 29 a is engaged with a groove portion 17 a formed on the outer periphery of the interlocking member 17. Therefore, the interlocking member 17 and the connecting piece 18 move up and down by the up-and-down movement of the elevating member 29, and the up-and-down movement of the connecting piece 18 is converted into the swing of the guide lever 20 through the linkage groove 18a and the roller 25. Thus, the guide cylinder 24 fixed to the lower end portion of the guide lever 20 is linearly moved left and right with respect to the sewing advance direction with the lever pin 21 as a fulcrum by the action of the swing mechanism from the staggered motor 30 to the guide arm 23. It swings back and forth.

上記の図１では、昇降部材２９が上限位置にあってガイドレバー２０が左側一杯に揺動した状態を示している。一方、図３はミシンヘッドＨの下部を正面から見た部分図であり、昇降部材２９が下限位置にあってガイドレバー２０が右側一杯に揺動した状態を示す図である。ガイドレバー２０のガイド筒２４は、図１に示す位置と図３に示す位置との間で、針棒２の往復動に同期して左右に往復揺動するようになっている。これにより、ガイド筒２４の先端に設けた刺繍材導出口２４ａから出た刺繍材Ｔが、所定のパターンで縫い進み方向に対して左右に千鳥振りされつつ針落ち位置へ供給されて、順次被縫製物に縫い付けられるようになっている。なお、上記した各図において、３１は周知の針板である。   FIG. 1 shows a state in which the elevating member 29 is at the upper limit position and the guide lever 20 is fully swung on the left side. On the other hand, FIG. 3 is a partial view of the lower part of the sewing head H as seen from the front, and shows the state where the elevating member 29 is at the lower limit position and the guide lever 20 is swung to the right. The guide cylinder 24 of the guide lever 20 reciprocally swings left and right in synchronization with the reciprocating movement of the needle bar 2 between the position shown in FIG. 1 and the position shown in FIG. As a result, the embroidery material T coming out from the embroidery material outlet 24a provided at the tip of the guide cylinder 24 is supplied to the needle drop position while being swung in a predetermined pattern to the left and right with respect to the sewing advance direction. It can be sewn on the sewing product. In each of the above drawings, 31 is a known throat plate.

ここで、上記構成のミシンヘッドＨにおいて、本縫いにより刺繍材Ｔを被縫製物に縫い着ける作業について説明する。まず、刺繍材Ｔを巻回したボビン２７をボビンブラケット２６にセットするとともに、刺繍材Ｔをボビン２７から繰り出してガイド筒２４に通し、刺繍材導出口２４ａから縫針３の針落ち位置へ導く。この状態で、刺繍枠（つまりは被縫製物）を所定の刺繍データに基づきＸＹ方向へ移動制御するとともに、針棒２を上下に駆動して縫針３と図示しない釜との機能によって周知の本縫いを行う。この際に、モータ７の駆動によって、布押え体１０が針棒２の上下駆動に対して所定のタイミングで上下動されて、布押え体１０の下端部に設けられている布押え部１０ａが被縫製物を押え付ける布押えの機能を果たすようになっている。   Here, the operation of sewing the embroidery material T onto the workpiece by the main sewing in the sewing head H having the above configuration will be described. First, the bobbin 27 around which the embroidery material T is wound is set on the bobbin bracket 26, and the embroidery material T is fed out from the bobbin 27 and passed through the guide tube 24, and is guided from the embroidery material outlet 24a to the needle drop position of the sewing needle 3. In this state, the embroidery frame (that is, the workpiece to be sewn) is controlled to move in the X and Y directions based on predetermined embroidery data, and the needle bar 2 is driven up and down to make a known book by the function of the sewing needle 3 and a hook (not shown). Perform sewing. At this time, by driving the motor 7, the presser foot 10 is moved up and down at a predetermined timing with respect to the vertical drive of the needle bar 2, and the presser foot 10 a provided at the lower end of the presser foot 10 is moved. It is designed to function as a presser foot that presses the work to be sewn.

ガイドレバー２０は、千鳥振りモータ３０の駆動によって図１に示す位置と図３に示す位置との間で所定のタイミングで左右に往復揺動される。この動作に伴いガイド筒２４により縫針３の針落ち位置へと案内されている刺繍材Ｔは、例えば針棒２の一往復毎（一縫い毎）に針落ち位置の左右に振られることとなる。これによって刺繍材Ｔは、千鳥縫いによって順次被縫製物に縫い着けられることとなる。この際に、回転筒１１はモータ１３の駆動によって回転され、レバーピン２１は被縫製物の移動に基づくミシンヘッドＨの相対的な進行方向の前面に位置するように制御される。   The guide lever 20 is reciprocally swung left and right at a predetermined timing between the position shown in FIG. 1 and the position shown in FIG. With this operation, the embroidery material T guided to the needle drop position of the sewing needle 3 by the guide cylinder 24 is swung to the left and right of the needle drop position, for example, every time the needle bar 2 is reciprocated (every stitch). . As a result, the embroidery material T is sequentially sewn onto the workpiece by zigzag stitching. At this time, the rotary cylinder 11 is rotated by driving the motor 13, and the lever pin 21 is controlled so as to be positioned on the front surface in the relative traveling direction of the sewing head H based on the movement of the sewing product.

図４は、上記千鳥縫いのときの千鳥振りの動作を説明するもので、ガイドレバー２０が左側に揺動した状態（図１に対応）を上から見た平面概略図で示している。なお、図４には従来知られた刺繍ミシンにおいて同じように左側に揺動した状態にある刺繍材導出口２４ａ′の位置が一点鎖線で示してある。本発明に係る刺繍ミシンのミシンヘッドＨにおいて、布押え体１０とガイドレバー２０とは互いに対向する位置にそれぞれ配置され、布押え部１０ａはその先端が略針落ち位置と並ぶ長さに設定してあるので、この図より明らかなように、刺繍材導出口２４ａが略針落ち位置Ｐと並ぶぐらいの近い位置まで、ガイド筒２４を布押え体１０に近づけて配置することができるようになる。   FIG. 4 is for explaining the staggered operation at the time of the staggered stitch, and shows a schematic plan view of the guide lever 20 swinging to the left (corresponding to FIG. 1) as seen from above. In FIG. 4, the position of the embroidery material outlet 24 a ′ that is similarly swung to the left side in a known embroidery sewing machine is indicated by a one-dot chain line. In the sewing head H of the embroidery sewing machine according to the present invention, the presser foot 10 and the guide lever 20 are respectively arranged at positions facing each other, and the presser foot portion 10a is set to a length in which the tip thereof is aligned with the substantially needle drop position. Therefore, as is clear from this figure, the guide cylinder 24 can be disposed close to the presser foot 10 so that the embroidery material outlet port 24a is substantially close to the needle drop position P. .

このようにして、刺繍材導出口２４ａを針落ち位置Ｐにより近い位置に近づけると、一つ前のステッチ位置Ｐａに刺繍材導出口２４ａを近づけることにもなって、該一つ前のステッチ位置Ｐａを中心とする刺繍材Ｔの振り角が、従来の位置に配置された刺繍材導出口２４ａ′から繰り出される刺繍材Ｔ′の振り角よりも大きくなる。したがって、刺繍材Ｔは針落ち位置Ｐからより大きく離れることになるので、刺繍材Ｔと縫針３との接触を確実に防止することができて、刺繍材Ｔの千鳥縫いを従来に比べ安定して行えることとなる。   In this way, when the embroidery material outlet 24a is brought closer to the needle drop position P, the embroidery material outlet 24a is also brought closer to the previous stitch position Pa. The swing angle of the embroidery material T around Pa is larger than the swing angle of the embroidery material T ′ fed out from the embroidery material outlet 24a ′ arranged at the conventional position. Accordingly, since the embroidery material T is further away from the needle drop position P, the contact between the embroidery material T and the sewing needle 3 can be reliably prevented, and the staggered stitching of the embroidery material T is more stable than before. Can be done.

図５はミシンヘッドＨの下部を示した側面拡大図であって、Ｕは上糸、Ｓは被縫製物である。千鳥縫いの第１針にて針棒２（縫針３）が下降すると、縫針３に通された上糸Ｕは縫針３とともに布押え体１０の糸ガイド１０ｃの半円部と凹部１０ｂとの内側に通される。第１針のステッチが形成されて針棒２が上昇されると、図５に示すように、縫針３から被縫製物Ｓへ繋がる上糸Ｕは糸ガイド１０ｃの半円部と凹部１０ｂとの内側に位置した状態のまま、すなわち上糸Ｕが糸ガイド１０ｃ、凹部１０ｂにて針落ち位置の付近から離れることなく案内されることとなる。これにより、被刺繍物Ｓを保持した刺繍枠（図示せず）が大きく移動されたときでも、上糸Ｕは凹部１０ｂから外れることはあっても糸ガイド１０ｃからは外れることがないため、常に上糸Ｕは確実に針落ち位置の付近に案内されている状態となる。したがって、従来の刺繍ミシンのようにして上糸Ｕが回転制御されるガイドレバー２０や布押え体１０に引っ掛かることがなく、それによる糸切れや針折れなどが発生することがない。さらに、この糸ガイド１０ｃで形成された半円部は布押え部１０ｂの上方に設けてあるため、略針落ち位置Ｐと並ぶぐらいまで針落ち位置Ｐに近い位置に配置したガイド筒２４の刺繍材導出口２４ａが直線的に往復揺動されても、刺繍材導出口２４ａは糸ガイド１０ｃを含む布押え体１０と干渉することがない。   FIG. 5 is an enlarged side view showing the lower part of the sewing head H. U is an upper thread and S is a sewing product. When the needle bar 2 (sewing needle 3) is lowered by the first stitch of the staggered stitch, the upper thread U passed through the sewing needle 3 and the inner side of the semicircular portion of the thread guide 10c of the presser foot 10 and the concave portion 10b together with the sewing needle 3. Passed through. When the stitch of the first needle is formed and the needle bar 2 is raised, as shown in FIG. 5, the upper thread U connected from the sewing needle 3 to the sewing product S is formed between the semicircular portion of the yarn guide 10c and the concave portion 10b. In this state, the upper thread U is guided by the thread guide 10c and the recess 10b without leaving the vicinity of the needle drop position. Thus, even when the embroidery frame (not shown) holding the embroidery object S is moved greatly, the upper thread U does not come off from the thread guide 10c even if it comes off from the recess 10b. The upper thread U is surely guided near the needle drop position. Therefore, the upper thread U is not caught on the guide lever 20 and the cloth presser body 10 whose rotation is controlled as in the case of a conventional embroidery sewing machine, and there is no occurrence of thread breakage or needle breakage. Further, since the semicircular portion formed by the thread guide 10c is provided above the presser foot portion 10b, the embroidery of the guide tube 24 arranged at a position close to the needle drop position P until it is substantially aligned with the needle drop position P. Even if the material outlet port 24a is reciprocally swung linearly, the embroidery material outlet port 24a does not interfere with the presser foot 10 including the thread guide 10c.
