PROBLEM TO BE SOLVED: To provide an embroidery machine which uses one actuator to perform both of the operation of changing the lower limit position of a cloth presser plate and the operation of hooking a needle thread after cutting and storing it in a thread storage mechanism.SOLUTION: The upper and lower positions of an adjustment plate 34 are restricted within a distance a by the rotation within 180 degrees of an eccentric pin 36 on the front end face of a flange 33 rotationally driven by an actuator 23. A bearing 51a of a cloth presser drive link 48 fitted in an L-shaped groove 43 of the adjustment plate 34 is engaged with a horizontal groove 43c while embroidery is performed and thereby restricts the lower limit position of a cloth presser plate 19 within the distance a. When a thread is switched to any other color thread, a needle bar drive part 45 stops a needle bar 18 and is moved to an uppermost position, and the bearing 51a of the cloth presser drive link 48 is moved from the horizontal groove 43c to a vertical groove 43a and is raised to an uppermost position 57 together with a cloth presser drive part 46, namely the cloth presser plate 19. The actuator 23 is driven, and a hook 28a enters below the cloth presser plate 19 raised from an embroidery surface by a distance b to hook a cut needle thread.

Description

本発明は、布押え板の下限位置を変化させる動作と切断後の上糸を掛け取って糸収納機構に収納する動作とを行う刺繍機に関する。   The present invention relates to an embroidery machine that performs an operation of changing a lower limit position of a presser foot plate and an operation of hooking an upper thread after cutting and storing it in a thread storage mechanism.

従来、多頭機又は単頭機を備えた刺繍機が知られている。刺繍機にはアーム部とヘッド部が一体のもの又は別体のものを着脱自在に合体させているものなどがある。いずれにしても、アーム部の駆動系で生成される上下駆動力により、ヘッド部の針棒、布押え板、天秤などの動作を規制している。   Conventionally, an embroidery machine including a multi-head machine or a single-head machine is known. Some embroidery machines have an arm portion and a head portion which are integrated or detachably combined with each other. In any case, operations of the needle bar, the cloth presser plate, the balance and the like of the head unit are regulated by the vertical driving force generated by the driving system of the arm unit.

ところで、布押え板の上下移動の基本動作は主軸カムからの駆動伝達で行われるが、布押え板の下限位置(下死点位置)を刺繍対象の加工布の厚さに応じて変化させる微細調整の動作はアクチュエータを用いて行われる。(例えば、特許文献1、2参照。)   By the way, the basic movement of the cloth presser plate up and down is performed by drive transmission from the spindle cam, but the lower limit position (bottom dead center position) of the work clamp plate is changed according to the thickness of the work cloth to be embroidered. The adjustment operation is performed using an actuator. (For example, see Patent Documents 1 and 2.)

特許文献1は、多頭式刺繍機の複数台のミシンヘッドに布押え足(布押え板)の下死点位置の高さを調整する調整機構を設け、各調整機構を連結軸で連結し、連結軸をアクチュエータで駆動するというものである。   Patent Document 1 provides an adjustment mechanism that adjusts the height of the bottom dead center position of the presser foot (cloth presser plate) on a plurality of sewing heads of a multi-head embroidery machine, and connects each adjustment mechanism with a connecting shaft. The connecting shaft is driven by an actuator.

特許文献2は、縫製速度に追従して昇降する布押えの下死点位置の高さを調節するために、主軸の回転運動を布押え棒の昇降運動に変換する昇降機構に対して布押えの下死点位置の高さを調節する調節機構を設け、その調節機構をステッピングモータによって調整駆動するというものである。   Patent Document 2 discloses a presser foot for a lifting mechanism that converts the rotational motion of the main shaft into the lifting motion of the presser bar in order to adjust the height of the bottom dead center position of the presser foot that moves up and down following the sewing speed. An adjustment mechanism for adjusting the height of the bottom dead center position is provided, and the adjustment mechanism is adjusted and driven by a stepping motor.

ところで、刺繍機は、作業衣の名入れ刺繍のように単色の糸で刺繍するものは別として一般的には、刺繍の模様に合わせて多色の糸が使用される。したがって、ミシンヘッドには刺繍に使用する糸の色数に合わせた数の針棒が装着されている。   By the way, an embroidery machine generally uses multi-colored threads in accordance with an embroidery pattern, except for embroidering with a single-colored thread, such as name-embroidered work clothes. Therefore, a needle bar having a number corresponding to the number of colors of threads used for embroidery is attached to the sewing head.

従来、色糸を切り替える際は、先行の上糸を針孔から数センチを残して切断し、そのままミシンアームが次の色糸の針棒を選択して刺繍を続行する。したがって、刺繍が進行していく過程で、先行の切断されていた上糸が針孔から抜け出し、再びその色糸で刺繍を継続しようとしたときに空縫いが生じて、その刺繍が不良品になってしまうという問題がある。   Conventionally, when changing the color thread, the preceding upper thread is cut leaving a few centimeters from the needle hole, and the sewing machine arm selects the needle bar of the next color thread and continues the embroidery. Therefore, as the embroidery progresses, the upper thread that has been cut out from the needle hole comes out of the needle hole, and when trying to continue embroidery with the colored thread again, empty stitching occurs, and the embroidery becomes defective. There is a problem of becoming.

この問題を解決するには、切断した上糸の端部を、針孔から抜け出さないように次回の使用時まで適宜の位置に押さえ込む又は仕舞い込んでおく必要があるが、その押さえ込み又は仕舞い込みの装置を動作せるためのアクチュエータが別途必要となってくる。   In order to solve this problem, it is necessary to press the end of the cut upper thread into an appropriate position until the next use so that it does not come out of the needle hole. A separate actuator is required to operate the device.

布押え板の下限位置(下死点位置)の調整と、切断された上糸の押さえとに、それぞれアクチュエータを設けていたのでは、ミシンアーム側の装置が大型化するという問題だけでなく、電動アクチュエータは高価なものであるからコストの上昇を招くという問題も発生する。   If the actuator is provided for the adjustment of the lower limit position (bottom dead center position) of the presser foot and the presser of the cut upper thread, not only the problem that the device on the machine arm side becomes large, Since the electric actuator is expensive, there is a problem that the cost increases.

本発明は、上記従来の課題を解決するものであって、布押え板の下限位置を変化させる動作と切断後の上糸を掛け取って糸収納機構に収納する動作の両方の動作を1個のアクチュエータを用いて行う刺繍機を提供することを目的とする。   The present invention solves the above-described conventional problems, and includes one operation for both changing the lower limit position of the presser plate and for picking up the upper thread after cutting and storing it in the yarn storage mechanism. It is an object of the present invention to provide an embroidery machine that uses an actuator.

上記課題を解決するために、本発明の刺繍機は、布押え板の下限位置の高さを刺繍対象とする加工布の厚さに応じて変化させる刺繍機において、電動アクチュエータと、該電動アクチュエータの動力を伝達機構により伝達されて回転する回転軸と、該回転軸の先端面に設けられた偏芯ピンと、該偏芯ピンに係合し該偏芯ピンの回転に応じて所定範囲で上下に移動する調節板と、該調節板の一面に、垂直溝、R付き角溝、水平溝とが連続して形成されたL字溝と、針棒駆動部を支点に布押さえ駆動部にリンクするリンクローラと同軸に連結され、上記L字溝に嵌入し、刺繍縫い取り実行時には上記水平溝の部分を往復して上記調節板の上下位置に追随し、刺繍縫い取り非実行時には上記垂直溝の部分において上記リンクローラの上下位置に追随する布押え板駆動ローラと、から成る駆動機構を備え、上記刺繍対象とする加工布の厚さに応じて上記電動アクチュエータを制御することにより、上記駆動機構を介して上記針棒駆動部の上記リンクローラから伝達される上記布押え板の上下動の下限位置を上記刺繍対象とする加工布の厚さに応じた高さに調整する、ように構成される。   In order to solve the above-described problems, an embroidery machine according to the present invention is an embroidery machine that changes the height of the lower limit position of the cloth presser plate in accordance with the thickness of a work cloth to be embroidered. A rotating shaft that is rotated by the power transmitted by the transmission mechanism, an eccentric pin provided on the tip surface of the rotating shaft, and engages with the eccentric pin and moves up and down within a predetermined range according to the rotation of the eccentric pin. An adjustment plate that moves to the center, an L-shaped groove in which a vertical groove, a square groove with R, and a horizontal groove are continuously formed on one surface of the adjustment plate, and a link to the cloth presser drive unit using the needle bar drive unit as a fulcrum Is connected to the link roller coaxially, and is inserted into the L-shaped groove. When the embroidery sewing is executed, the horizontal groove is reciprocated to follow the vertical position of the adjustment plate. When the embroidery sewing is not executed, the vertical groove is Follow the vertical position of the link roller in A cloth presser plate driving roller, and by controlling the electric actuator in accordance with the thickness of the work cloth to be embroidered, the needle bar driving section of the needle bar driving unit is controlled by the driving mechanism. The lower limit position of the vertical movement of the cloth presser plate transmitted from the link roller is adjusted to a height corresponding to the thickness of the work cloth to be embroidered.

この刺繍機において、例えば、上記電動アクチュエータから上記伝達機構を介して伝達される動力により進退するフック機構を更に備え、上記布押え板は、上記布押え板駆動ローラが上記刺繍縫い取り非実行時において上記L字溝の上記垂直溝の部分に在るとき、上記偏芯ピンの回転と上記調節板の上下移動に関りなく、針棒先端の針と共に刺繍縫い取りに必要な上限位置よりも上の位置にあり、上記フック機構のフックは、上記針の上糸の切断後の上記針より下に延在する上記上糸を掛け取って糸収納機構に収納する、ように構成される。また、この刺繍機において、例えば、上記電動アクチュエータは、パルスモータ又はサーボモータである。   The embroidery machine further includes, for example, a hook mechanism that moves forward and backward by power transmitted from the electric actuator via the transmission mechanism, and the cloth presser plate is in a state where the embroidery sewing is not executed by the cloth presser plate driving roller. When located in the vertical groove portion of the L-shaped groove, it is above the upper limit position necessary for embroidery sewing together with the needle at the tip of the needle bar, regardless of the rotation of the eccentric pin and the vertical movement of the adjustment plate. And the hook of the hook mechanism is configured to hook the upper thread extending below the needle after cutting the upper thread of the needle and store it in the thread storage mechanism. In the embroidery machine, for example, the electric actuator is a pulse motor or a servo motor.

本発明は、切断後の上糸を掛け取って糸収納機構に収納するので、先行の切断されていた上糸が針孔から抜け出して再びその色糸で刺繍を継続しようとしたときに空縫いが生じて刺繍が不良品になってしまうという不具合が解消されるという効果を奏する。
また、布押え板の下限位置を変化させる動作と切断後の上糸を掛け取って糸収納機構に収納する動作の両方の動作を1個のアクチュエータを用いて行うので、異なる2つの動作のために2個のアクチュエータを備える必要がなく経済的であるという効果を奏する。
In the present invention, the upper thread after being cut is hooked and stored in the thread storage mechanism, so that when the preceding upper thread that has been cut out comes out of the needle hole and tries to continue embroidery with the colored thread again, the empty stitch is performed. This produces an effect of eliminating the problem that the embroidery becomes a defective product.
In addition, both the operation of changing the lower limit position of the presser foot and the operation of hooking the upper thread after cutting and storing it in the thread storage mechanism are performed using one actuator. It is not necessary to provide two actuators, and it is economical.

And are shown separately.

一方、ミシンヘッド5の針棒部26は、針棒18、針棒被駆動部52、布押え被駆動部53、布押え板保持部54とで構成されている。針棒被駆動部52は針棒18に固定されている。この針棒被駆動部52は係合突部52aを備えている。係合突部52aは、ミシンアーム6の針棒部駆動部25の針棒駆動部45の係合口45aに係合する。   On the other hand, the needle bar portion 26 of the sewing machine head 5 includes the needle bar 18, the needle bar driven portion 52, the presser foot driven portion 53, and the presser foot holding portion 54. The needle bar driven portion 52 is fixed to the needle bar 18. The needle bar driven portion 52 includes an engaging protrusion 52a. The engagement protrusion 52 a is engaged with the engagement port 45 a of the needle bar drive unit 45 of the needle bar drive unit 25 of the sewing machine arm 6.

布押え被駆動部53は、針棒被駆動部52よりも下方において針棒18に摺動可能に嵌入している。布押え被駆動部53は、ミシンアーム6との対抗面の上端部に係合口53aを備えている。係合口53aは、ミシンアーム6の針棒部駆動部25の布押え駆動部46の係合突部46bに係合する。   The presser foot driven portion 53 is slidably fitted into the needle bar 18 below the needle bar driven portion 52. The presser foot driven portion 53 includes an engagement port 53 a at the upper end of the surface facing the sewing machine arm 6. The engagement port 53 a engages with the engagement protrusion 46 b of the presser foot drive unit 46 of the needle bar drive unit 25 of the sewing machine arm 6.

また、布押え被駆動部53は、上端部の係合口53aとは反対側に回転止め軸55との係合部を形成されている。回転止め軸55は、上端を針棒被駆動部52に固定され、下端部を布押え被駆動部53との係合部に摺動可能に係合させて、布押え被駆動部53の針棒18周りの回転を禁止している。   In addition, the presser foot driven portion 53 has an engaging portion with the rotation stop shaft 55 on the opposite side of the upper end portion from the engaging port 53a.

布押え板保持部54は短いシャフト56を介して布押え被駆動部53に固定して連結され、下端部に布押え板19を保持し、布押え被駆動部53の上下の移動に従って上下に移動する。   The presser foot holding portion 54 is fixedly connected to the presser foot driven portion 53 via a short shaft 56, holds the presser foot plate 19 at the lower end, and moves up and down as the presser foot driven portion 53 moves up and down. Moving.

図3(a),(b)に示す針棒部駆動部25の針棒駆動部45は、他の色糸に切り替えるために針棒18を停止させるときは、最上位置に移動する。これにより、布押え駆動リンク48も布押え駆動部46と共に最上位置に引き上げられる。   The needle bar drive unit 45 of the needle bar unit drive unit 25 shown in FIGS. 3A and 3B moves to the uppermost position when the needle bar 18 is stopped to switch to another color thread. Thereby, the presser foot drive link 48 is also lifted to the uppermost position together with the presser foot drive unit 46.

このとき、調節板34が前述したように偏心ピン36の回転偏心差(最下位置41と最上位置42との間の距離a)だけしか上下移動できないことに対して、布押え駆動リンク48の下端部のベアリング51aは、図4(c)に示すように、最下位置41から距離aよりも大きな距離bだけ離れたベアリング最上位置57に引き上げられる。   At this time, as described above, the adjustment plate 34 can move up and down only by the rotational eccentricity difference (the distance a between the lowest position 41 and the highest position 42) of the eccentric pin 36, whereas the work clamp drive link 48 As shown in FIG. 4C, the lower end bearing 51a is pulled up to the bearing uppermost position 57 that is separated from the lowermost position 41 by a distance b larger than the distance a.

これにより、上述したように、調節板34が図4(a),(b)に示す最下位置41と最上位置42との間の距離aしか上下移動出来ないため、ベアリング51aは、刺繍実行時の調節板34のL字溝43の水平溝43cの部分にとどまっていることが出来ず、図4(c)に示すようにR付き角溝43bに沿って垂直溝43aの部分に移動する。   As a result, as described above, the adjustment plate 34 can move up and down only by the distance a between the lowermost position 41 and the uppermost position 42 shown in FIGS. 4 (a) and 4 (b). It is not possible to stay in the horizontal groove 43c portion of the L-shaped groove 43 of the adjustment plate 34 at the time, and moves to the vertical groove 43a portion along the R-shaped square groove 43b as shown in FIG. 4 (c). .

これに応じて、布押え板19も、ベアリング51a、ベアリング51b、水平溝46a、布押え駆動部476、布押え駆動部53を介して、図4(d),(e)に示す最下位置58と最上位置59の距離a内の移動位置から、大きく上に離れた距離bの刺繍非実行位置61に移動する。   Correspondingly, the presser foot plate 19 is also moved to the lowest position shown in FIGS. 4D and 4E via the bearing 51a, the bearing 51b, the horizontal groove 46a, the presser foot drive unit 476, and the presser foot drive unit 53. 58 and the uppermost position 59 move from a movement position within a distance a to an embroidery non-execution position 61 at a distance b far away from the upper position.

この状態で、アクチュエータ23が駆動され、歯付きベルト27が往復回転して偏心ピン軸32が回転しても、つまり偏心ピンフランジ33に取り付けられている偏心ピン36が偏心回転しても、つまり調節板34が上下動しても、ベアリング51aはL字溝43の垂直溝43aに嵌入しているので、布押え被駆動部52つまり布押え板19は図4(f)に示す最上位置61から動くことはない。   In this state, even if the actuator 23 is driven and the toothed belt 27 reciprocates and the eccentric pin shaft 32 rotates, that is, even if the eccentric pin 36 attached to the eccentric pin flange 33 rotates eccentrically, that is, Even if the adjustment plate 34 moves up and down, the bearing 51a is fitted in the vertical groove 43a of the L-shaped groove 43, so that the cloth presser driven portion 52, that is, the cloth presser plate 19 is in the uppermost position 61 shown in FIG. Will not move from.

このタイミングでアクチュエータ23が駆動され、歯付きベルト27が往復回転して、フック保持部28、すなわちフック28aが進退駆動される。これによりフック28aは図4(f),(i)に示すように、布押え板19の針挿通孔58の下方の距離bの間隙に潜り込むように動作して切断された上糸の針21の針孔より下方に延在する端部を掛け取る。   At this timing, the actuator 23 is driven, the toothed belt 27 is reciprocally rotated, and the hook holding portion 28, that is, the hook 28a is driven forward and backward. As a result, as shown in FIGS. 4 (f) and 4 (i), the hook 28a operates so as to sink into the gap of the distance b below the needle insertion hole 58 of the presser foot plate 19 and is cut through the needle 21 of the upper thread. The end extending below the needle hole is hooked.

図5(a)は1色の刺繍ステップを終えた針21と上糸62の状態を示す図、図5(b)は上糸62を下釜部4の可動刃63で切断する直前の状態を示す図、図5(c)は切断後の上糸62をフック28aが掛け取る状態を示す図、図5(d)は掛け取った上糸端部62aを糸端収納部64に収納する状態を示す図である。このように、フック28aは、掛け取った上糸端部を糸端収納部に収納する。   FIG. 5A is a view showing the state of the needle 21 and the upper thread 62 after the embroidery step for one color is completed, and FIG. 5B is a state immediately before the upper thread 62 is cut by the movable blade 63 of the lower hook portion 4. FIG. 5 (c) is a diagram showing a state in which the upper thread 62 after being cut is hooked by the hook 28a, and FIG. 5 (d) is a state in which the hooked upper thread end portion 62a is stored in the yarn end storage portion 64. FIG. In this way, the hook 28a stores the hooked upper yarn end portion in the yarn end storage portion.

図3(a)に示す針棒部26が刺繍実行中は、図3(a),(b)に示す針棒部駆動部25の針棒駆動部45は下方に下がって上下動している。ベアリング51aは、図4(a),(b)に示すようにL字溝43の水平溝43cに係合して水平方向に摺動している。これにより、布押え板19は、調節板34の上下位置に対応する位置に下限位置を規制されて刺繍媒体を抑えている。   While the needle bar portion 26 shown in FIG. 3 (a) is being embroidered, the needle bar drive portion 45 of the needle bar portion drive portion 25 shown in FIGS. 3 (a) and 3 (b) moves downward and moves up and down. . As shown in FIGS. 4A and 4B, the bearing 51a is engaged with the horizontal groove 43c of the L-shaped groove 43 and slides in the horizontal direction. As a result, the cloth presser plate 19 is restrained in the lower limit position at a position corresponding to the vertical position of the adjustment plate 34 to suppress the embroidery medium.

ここで、アクチュエータ23が刺繍媒体の厚さに対応して制御機構によって駆動されると、その駆動に応じた歯付きベルト27の回転距離、すなわち偏心ピン軸32の回転角度、つまり偏心ピン36の偏心回転量に応じた上下動が調節板34に伝達される。   Here, when the actuator 23 is driven by the control mechanism corresponding to the thickness of the embroidery medium, the rotation distance of the toothed belt 27 according to the drive, that is, the rotation angle of the eccentric pin shaft 32, that is, the eccentric pin 36. Vertical movement according to the amount of eccentric rotation is transmitted to the adjustment plate 34.

調節板34の上下動は、L字溝43の水平溝43c、布押え駆動リンク48のベアリング51a、51b、布押え駆動部46の水平溝46a,布押え駆動部46,係合突部46b,係合口53a,布押え被駆動部53、を介して布押え板19に伝達される。これにより、布押え板19の下限位置を任意のタイミングで変化させることができる。   The adjustment plate 34 is moved up and down by a horizontal groove 43c of the L-shaped groove 43, bearings 51a and 51b of the presser foot drive link 48, a horizontal groove 46a of the presser foot drive portion 46, a presser foot drive portion 46, an engaging protrusion 46b, It is transmitted to the presser foot plate 19 through the engagement port 53 a and the presser foot driven portion 53. Thereby, the lower limit position of the cloth presser plate 19 can be changed at an arbitrary timing.

このように、本発明の実施例1によれば、布押え板の下限位置を変化させる動作と切断後の上糸を掛け取って糸収納機構に収納する動作の両方の動作を1個のアクチュエータを用いて行う刺繍機を提供することが可能となる。   Thus, according to the first embodiment of the present invention, both the operation of changing the lower limit position of the presser plate and the operation of hooking the upper thread after cutting and storing it in the thread storage mechanism are performed by one actuator. It is possible to provide an embroidery machine that uses the embroidery machine.
