Description

本発明は、例えばショーツや水着等の裁断生地の脚部にレースや平ゴムなどの長尺帯状物を重ね合わせて縫い付ける場合に用いられる長尺帯状物縫い付け用ミシンに関する。 The present invention relates to a sewing machine for sewing a long strip, for example, which is used when a long strip such as lace or flat rubber is superposed and sewn on a leg of a cutting fabric such as shorts or a swimsuit.

通常、ショーツや水着等は、図７に示すように、両脚部となる側縁部Ｗｅ，Ｗｅが湾曲した特殊な形状の裁断生地Ｗが用いられる。そして、図８に示すように、該裁断生地Ｗの両脚部となる湾曲側縁部Ｗｅ，Ｗｅ上にレースや平ゴム等の長尺帯状物Ｔ，Ｔを縫い付け、その後、裁断生地Ｗ全体を二つ折りして脇縫いを行って胴部周りを形成することにより所定のショーツや水着等の縫製品が作製される。 Usually, for shorts, swimwear and the like, as shown in FIG. 7, a cutting cloth W having a special shape in which the side edge portions We and We, which are both legs, are curved is used. Then, as shown in FIG. 8, long strips T, T such as lace or flat rubber are sewn on the curved side edge portions We, We, which are both legs of the cutting fabric W, and then the entire cutting fabric W is sewn. A sewn product such as a predetermined shorts or a swimsuit is produced by folding the cloth in half and sewing it sideways to form the circumference of the body.

上記のような縫製品を作製する際、一般的には、図９に示すように、ミシンの針板１上に複数の裁断生地、すなわち、先行生地Ｗ１と後続生地Ｗ２を次々とセットして、これら複数の裁断生地Ｗ１，Ｗ２を針板１に形成された針落ち部を含む縫製部２に対して順次送りながら、前記縫製部２よりも縫製進行方向Ｙの上手側位置において先行生地Ｗ１及び後続生地Ｗ２の側縁部Ｗｅ，Ｗｅ上に長尺帯状物Ｔを連続に送り出し供給して該長尺帯状物Ｔを連続的に縫い付け、所定量の縫い付けが終わった後に、先行生地Ｗ１と後続生地Ｗ２との間に繋がる帯状物部分Ｔａを、手鋏等を用いて手動切断していた。 When producing a sewn product as described above, generally, as shown in FIG. 9, a plurality of cutting fabrics, that is, a preceding fabric W1 and a succeeding fabric W2 are set one after another on the needle plate 1 of the sewing machine. , While sequentially feeding these plurality of cutting fabrics W1 and W2 to the sewing portion 2 including the needle drop portion formed on the needle plate 1, the preceding fabric W1 is located at a position on the upper side of the sewing progress direction Y with respect to the sewing portion 2. And, the long strip-shaped object T is continuously sent out and supplied onto the side edge portions We and We of the succeeding fabric W2, and the long strip-shaped object T is continuously sewn. The strip-shaped portion Ta connected between W1 and the succeeding cloth W2 was manually cut using a hand scissors or the like.

しかし、この場合は、縫い付けた帯状物切断のために手鋏等による手動作業が必要であり、その度に縫製作業を一時中断しなければならないので、縫製作業効率が悪くて生産性の低下及び生産コストの上昇を招きやすく、更に、手鋏等の使用に伴い生地を傷付けやすいという問題がある。 However, in this case, manual work using hand scissors or the like is required to cut the sewn strip, and the sewing work must be temporarily interrupted each time, resulting in poor sewing work efficiency and reduced productivity. In addition, there is a problem that the production cost is likely to increase, and the fabric is easily damaged by the use of hand scissors or the like.

そこで、上記のような手鋏等による手動作業を不要とするために、図１０に示すように、縫製部２より縫製進行方向Ｙの下手側位置に縫い付けた長尺帯状物Ｔを縫製進行方向Ｙに対して略直交する方向、つまり、長尺帯状物Ｔの幅方向に沿って切断する帯状物切断装置３を配置したミシンが従来から提案されていた（例えば、特許文献１参照）。
なお、帯状物切断装置３については、後述する本発明の実施形態で詳しく説明するが、その主要構成は、固定下メス３Ａと該下メス３Ａに対して上方から下方に向けて摺接揺動自在な可動上メス３Ｂとからなる。Therefore, in order to eliminate the need for manual work using hand scissors or the like as described above, as shown in FIG. 10, a long strip-shaped object T sewn from the sewing portion 2 to the lower position in the sewing progress direction Y is sewn. Conventionally, a sewing machine has been proposed in which a strip-shaped object cutting device 3 for cutting along a direction substantially orthogonal to the direction Y, that is, a width direction of a long strip-shaped object T is arranged (see, for example, Patent Document 1).
The strip-shaped object cutting device 3 will be described in detail in the embodiment of the present invention described later, but its main configuration is a sliding contact swing from above to downward with respect to the fixed lower female 3A and the lower female 3A. It consists of a freely movable upper female 3B.

実公平２−１０９９５号公報 Jitsufuku No. 2-10995

上記したような構成の帯状物切断装置３を有する従来の長尺帯状物縫い付け用ミシンを用いて、複数の裁断生地Ｗ１，Ｗ２を針板１上に順次セットし、且つ、縫製部２に対して順次縫製進行方向Ｙに送りながら、それら先行生地Ｗ１及び後続生地Ｗ２の湾曲側縁部Ｗｅ，Ｗｅ上に長尺帯状物Ｔを連続に送り出し供給して長尺帯状物Ｔを連続的に縫い付ける場合、裁断生地が図７に示すような特殊な形状であるために、先行生地Ｗ１の帯状物縫い付け終端部と後続生地Ｗ２の帯状物縫い付け始端部とを両者間に帯状物切断装置３による切断作用に必要最少限の間隔が確保されるように近接させると、後続生地Ｗ２の縫い始め端部の一部分が帯状物縫い付け始端部よりも縫製進行方向Ｙの下手側にはみ出すことになり、このはみ出し生地部分が帯状物切断装置３による長尺帯状物Ｔの切断作用時に不要に切断されてしまうという不良事態を発生することになる。 Using a conventional sewing machine for sewing long strips having the above-described strip cutting device 3, a plurality of cutting fabrics W1 and W2 are sequentially set on the needle plate 1 and placed on the sewing portion 2. On the other hand, while sequentially feeding in the sewing progress direction Y, the long strips T are continuously fed and supplied onto the curved side edges We and We of the preceding fabrics W1 and the succeeding fabrics W2, and the long strips T are continuously fed. When sewing, since the cut fabric has a special shape as shown in FIG. 7, the strip-shaped object cutting end portion of the preceding fabric W1 and the strip-shaped object sewing start end portion of the succeeding fabric W2 are cut between the two. When brought close to each other so as to secure the minimum interval required for the cutting action by the device 3, a part of the sewing start end portion of the succeeding fabric W2 protrudes to the lower side of the sewing progress direction Y from the strip-shaped object sewing start end portion. Therefore, a defective situation occurs in which the protruding fabric portion is unnecessarily cut during the cutting action of the long strip-shaped object T by the strip-shaped object cutting device 3.

このような後続生地Ｗ２の一部生地部分が不要に切断される不良事態の発生を避けるためには、先行生地Ｗ１の帯状物縫い付け終端部Ｗ１ｅと後続生地Ｗ２の帯状物縫い付け始端部Ｗ２ｂとの間に、図１０に示すように、後続生地Ｗ２の縫い始め端部の一部分がはみ出すことのないだけの所定間隔ｄをあけて長尺帯状物Ｔの縫い付けを行い、生地送りによって前記所定間隔ｄに対応する帯状物部分が帯状物切断装置３による切断位置に達したとき、該帯状物切断装置３を作動させることにより、後続生地Ｗ２の一部生地部分を不要に切断することなく長尺帯状物Ｔの切断を行う方法が採られていた。従って、図７に示すような特殊な形状の裁断生地Ｗを対象にして複数の裁断生地Ｗ１，Ｗ２の側縁部Ｗｅ，Ｗｅに連続的に長尺帯状物Ｔを縫い付ける場合、図１０のＤで示す帯状物部分Ｔｂが無駄（ロス）になるという問題があり、また、この無駄な帯状物部分Ｔｂは、脇縫いのとき、ミシンあるいは手動で切断しなければならないという問題もあった。 In order to avoid the occurrence of such a defective situation in which a part of the subsequent fabric W2 is unnecessarily cut, the strip-shaped object sewing end portion W1e of the preceding fabric W1 and the strip-shaped object sewing start end portion W2b of the succeeding fabric W2 As shown in FIG. 10, the long strip-shaped object T is sewn at a predetermined interval d so that a part of the sewing start end portion of the succeeding fabric W2 does not protrude, and the fabric is fed to the above. When the strip-shaped portion corresponding to the predetermined interval d reaches the cutting position by the strip-shaped object cutting device 3, by operating the strip-shaped object cutting device 3, a part of the subsequent fabric W2 is not cut unnecessarily. A method of cutting the long strip T has been adopted. Therefore, when the long strip-shaped object T is continuously sewn on the side edge portions We and We of the plurality of cutting fabrics W1 and W2 for the cutting fabric W having a special shape as shown in FIG. 7, FIG. There is a problem that the strip-shaped portion Tb indicated by D is wasted (loss), and there is also a problem that the waste strip-shaped portion Tb must be cut by a sewing machine or manually at the time of side stitching.

本発明は上述の実情に鑑みてなされたもので、複数の生地の側縁部上に連続して長尺帯状物を縫い付ける場合、後続生地の一部分を不要に切断する不良事態の発生を回避しつつ、帯状物を無駄の発生がないように自動的にかつ的確に切断処理することができる長尺帯状物縫い付け用ミシンを提供することを目的としている。 The present invention has been made in view of the above circumstances, and when a long strip is continuously sewn on the side edges of a plurality of fabrics, the occurrence of a defective situation in which a part of the subsequent fabric is unnecessarily cut is avoided. At the same time, it is an object of the present invention to provide a sewing machine for sewing long strips, which can automatically and accurately cut strips without waste.

A sewn portion including a needle drop portion formed on the needle plate and a strip-shaped object that sends out and supplies a long strip-shaped object so as to overlap the side edge portion of the fabric at a position on the upper side of the sewn portion in the sewing progress direction. The feed and supply device and a long strip that is arranged at a position on the lower side in the sewing progress direction from the sewn portion and sewn on the side edge portion of the fabric when passing through the sewn portion are orthogonal to the sewn progress direction. A sewing machine for sewing a long strip, which is provided with a strip cutting device for cutting along the width direction of the strip, and is a sewing machine for sewing a long strip of the preceding fabric, and a long strip of the preceding fabric and a long strip of the succeeding fabric. A part of the sewing start end portion of the succeeding fabric is sewn more than the strip-shaped object sewing start end portion by bringing it close to the sewing start end portion so as to secure the minimum space required for cutting the strip-shaped object cutting device. In the case where a long strip-shaped object that is continuously fed and supplied onto the side edges of the plurality of fabrics while being sequentially fed while protruding to the lower side in the direction is continuously sewn at the sewn portion. When the sewing end end of the preceding fabric reaches a predetermined strip-shaped object cutting position, it is possible to advance and move from the upper position on the lower side in the sewing progress direction to the lower position on the upper side in the sewing progress direction. of sewing have starting end of the subsequent dough, than contact with said strip cutting position the dough portion protruding said dough portion that protrudes downstream side of sewing the advancing direction than the sewing portion of the long strip Consists of a fabric presser rod that pushes back to the upper side in the sewing progress direction, and a cylinder that moves the fabric presser rod forward and backward drive between the lower position on the lower side in the sewing progress direction and the lower position on the upper side in the sewing progress direction. The fabric pressing device is provided, and a non-slip rubber that comes into contact with the protruding fabric portion of the succeeding fabric is attached to the tip of the fabric pressing rod of the fabric pressing device.

上記のごとき特徴を有する本発明に係る長尺帯状物縫い付け用ミシンによれば、複数の生地を順次送りながらそれら複数の生地の側縁部上に連続して送り出し供給される長尺帯状物を前記縫製部で連続的に縫い付ける場合において、先行生地の帯状物縫い付け終端部と後続生地の帯状物縫い付け始端部とを両者間に帯状物切断装置の切断作用に必要最少限の間隔を確保するように近接させることによって、帯状物を無駄の発生がない位置で自動的に切断することができる。それでいて、先行生地の帯状物縫い付け終端部と後続生地の帯状物縫い付け始端部との間に帯状物切断装置の切断作用に必要最少限の間隔を確保するように近接させることに伴い後続生地の縫い始め端部の一部分が帯状物縫い付け始端部よりも縫製進行方向の下手側にはみ出す状態で連続的に縫い付けが行われることになるが、この場合、先行生地の縫い終わり端部が所定の帯状物切断位置に到達した時点で、生地押し止め装置の生地押えロッドが縫製進行方向の下手側上方位置から縫製進行方向の上手側下方位置に向かって進出移動することによって、生地押えロッドの先端部が後続生地における縫製進行方向の下手側へのはみ出し生地部分に当接して該はみ出し生地部分を縫製進行方向の上手側に押し戻す作用が発揮されることになるため、前記はみ出し生地部分が帯状物切断装置により不要に切断されるといった不良事態の発生を確実に回避しつつ、上述のとおり、帯状物に無駄を発生しないように的確に切断処理することができるという効果を奏する。According to the sewing machine for sewing a long strip-shaped object according to the present invention having the above-mentioned characteristics, a long strip-shaped object that is continuously fed and supplied onto the side edges of the plurality of fabrics while sequentially feeding the plurality of fabrics. Is continuously sewn at the sewn portion, the minimum distance required for the cutting action of the strip-shaped object cutting device between the strip-shaped object sewing end portion of the preceding fabric and the strip-shaped object sewing start end portion of the succeeding fabric. It is possible to automatically cut the strip-shaped object at a position where no waste is generated by bringing the strips close to each other so as to secure the above. Nevertheless, the succeeding fabric is brought close to the end of the strip-shaped sewing of the preceding fabric and the starting end of the strip-shaped sewing of the succeeding fabric so as to secure the minimum distance necessary for the cutting action of the strip-cutting device. The sewing is continuously performed with a part of the sewing start end end protruding from the strip-shaped object sewing start end portion to the lower side in the sewing progress direction. In this case, the sewing end end portion of the preceding fabric is given when it reaches the strip cutting position, depending on the fabric presser rod fabric press stop device moves forward movement toward the upstream side position below the sewing traveling direction from the downstream side upper position of the sewing direction of travel, the fabric presser Since the tip of the rod comes into contact with the protruding fabric portion of the succeeding fabric to the lower side in the sewing progress direction and pushes the protruding fabric portion back to the upper side in the sewing progress direction, the protruding fabric portion As described above, it is possible to perform an accurate cutting process so as not to generate waste in the strip-shaped object, while surely avoiding the occurrence of a defective situation such as the strip-shaped object being cut unnecessarily by the strip-shaped object cutting device.

次に、上記のように構成された本実施の形態に係る長尺帯状物（テープ）縫い付け用ミシンＭを用いて、ショーツや水着などの裁断生地Ｗの湾曲側縁部Ｗｅに沿ってレースや平ゴム等のテープＴを縫い付ける動作について、主に図５及び図６を参照しながら説明する。 Next, using the sewing machine M for sewing a long strip (tape) according to the present embodiment configured as described above, lace is performed along the curved side edge We of the cutting fabric W such as shorts and swimwear. The operation of sewing the tape T such as flat rubber or flat rubber will be described mainly with reference to FIGS. 5 and 6.

ミシンの針板１上に複数の裁断生地、すなわち、先行生地Ｗ１と後続生地Ｗ２を次々とセットして、これら先行、後続生地Ｗ１，Ｗ２を針板１に形成された針落ち部を含む縫製部２に対して順次送りながら、前記縫製部２よりも縫製進行方向Ｙの上手側位置において先行生地Ｗ１及び後続生地Ｗ２の湾曲側縁部Ｗｅ，Ｗｅ上にテープＴを連続に送り出し供給して該テープＴを連続的に縫い付ける。 A plurality of cutting fabrics, that is, a preceding fabric W1 and a succeeding fabric W2 are set one after another on the needle plate 1 of the sewing machine, and the preceding and succeeding fabrics W1 and W2 are sewn including a needle drop portion formed on the needle plate 1. While sequentially feeding to the portion 2, the tape T is continuously fed and supplied onto the curved side edges We and We of the preceding fabric W1 and the succeeding fabric W2 at a position on the upper side of the sewing progress direction Y with respect to the sewing portion 2. The tape T is continuously sewn.

上記のように、先行生地Ｗ１及び後続生地Ｗ２の湾曲側縁部Ｗｅ，ＷｅにテープＴを連続縫い付ける場合において、先行生地Ｗ１のテープ縫い付け終端部Ｗ１ｅと後続生地Ｗ２のテープ縫い付け始端部Ｗ２ｂとを両者間にテープ切断装置３の切断作用に必要最少限の間隔を確保するように近接させて連続縫い付けを行うことによって、先行生地Ｗ１のテープ縫い付け終端部Ｗ１ｅと後続生地Ｗ２のテープ縫い付け始端部Ｗ２ｂとの最少限の間隔部が切断位置に到達した時点で、投光器３１ａ及び受光器３１ｂによる動作指令を受けてテープ切断装置３が切断動作して、テープＴに無駄を発生しない状態で自動的にテープ切断することができる。 As described above, when the tape T is continuously sewn to the curved side edges We and We of the preceding fabric W1 and the succeeding fabric W2, the tape sewing end portion W1e of the preceding fabric W1 and the tape sewing start end portion of the succeeding fabric W2. By performing continuous sewing with W2b close to each other so as to secure the minimum distance required for the cutting action of the tape cutting device 3, the tape sewing end portion W1e of the preceding fabric W1 and the succeeding fabric W2 are sewn together. When the minimum distance from the tape sewing start end W2b reaches the cutting position, the tape cutting device 3 cuts in response to an operation command from the floodlight 31a and the receiver 31b, causing waste in the tape T. The tape can be cut automatically without using it.

それでいて、先行生地Ｗ１のテープ縫い付け終端部Ｗ１ｅと後続生地Ｗ２のテープ縫い付け始端部Ｗ２ｂとの間にテープ切断装置３の切断作用に必要最少限の間隔を確保するように近接させて連続的な縫い付けを行う場合は、後続生地Ｗ２の縫い始め端部の一部分Ｗ２ｃがテープ縫い付け始端部Ｗ２ｂよりも縫製進行方向Ｙの下手側にはみ出したままでの縫い付けが行われ、このままであると、テープ切断装置３によるテープ切断時に前記はみ出し生地部分Ｗ２ｃが不要に切断されてしまうおそれがある。 Nevertheless, the tape sewing end portion W1e of the preceding fabric W1 and the tape sewing starting end portion W2b of the succeeding fabric W2 are brought close to each other so as to secure the minimum distance necessary for the cutting action of the tape cutting device 3 and continuously. When sewing is performed, the sewing is performed with a part W2c of the sewing start end portion of the succeeding fabric W2 protruding from the tape sewing starting end portion W2b to the lower side of the sewing progress direction Y, and it is assumed that the sewing is performed as it is. When the tape is cut by the tape cutting device 3, the protruding cloth portion W2c may be cut unnecessarily.

かかる事態を避けるべく本実施の形態によれば、先行生地Ｗ１の縫い終わり端部が所定のテープ切断位置に到達した時点で、前記生地押し止め装置８の生地押えロッド２５がエアシリンダ２６の駆動に伴い縫製進行方向の下手側上方位置から縫製進行方向の上手側下方位置に向かって進出移動することによって、生地押えロッド２５の先端部の滑り止めゴム２７が、後続生地Ｗ２の前記はみ出し生地部分Ｗ２ｃに当接して該はみ出し生地部分Ｗ２ｃを前記テープ切断装置３による切断位置よりも縫製進行方向Ｙの上手側の位置に押し戻す作用が発揮され、これにより前記はみ出し生地部分Ｗ２ｃを切断位置から確実に回避させることが可能であるために、前記はみ出し生地部分Ｗ２ｃがテープ切断装置３により不要に切断されるといった不良事態の発生を確実に回避することができる。In order to avoid such a situation, according to the present embodiment, when the sewing end end of the preceding fabric W1 reaches a predetermined tape cutting position, the fabric pressing rod 25 of the fabric pressing device 8 drives the air cylinder 26. Thus to advance to move toward the upstream side position below the sewing traveling direction from the downstream side upper position of the sewing traveling direction with the anti-slip rubber 27 of the distal end portion of the fabric presser rod 25, the protruding dough subsequent fabric W2 The action of abutting on the portion W2c and pushing the protruding fabric portion W2c back to a position on the upper side of the sewing progress direction Y from the cutting position by the tape cutting device 3 is exerted, whereby the protruding fabric portion W2c is surely pushed from the cutting position. in order to be avoided is possible, the protruding dough portion W2c can be avoided reliably defective situation is unnecessarily cut by the tape cutting device 3.

そして、テープ切断後は、前記生地押し止め装置８により縫製進行方向Ｙの上手側の位置に押し留められることで皺皺の状態になっている前記はみ出し生地部分Ｗ２ｃに向けて前記エア吹き出し管装置９のエア吹き出し口部３０ａからエアを吹き付けることにより、該はみ出し生地部分Ｗ２ｃを縫製進行方向Ｙの下手側に飛ばし移行させて後続生地Ｗ２の生地送りベルト７とクロスプレート４との間への移入を補助することが可能となり、かつ、後続生地Ｗ２を縫製作業者が手で送らなくても生地送りベルト７が自動的に送ってくれることになる。従って、複数の生地に対するテープＴの連続縫い付け作業を容易かつスムーズに実行することができる。 Then, after the tape is cut, the air blowing tube device is pressed toward the protruding fabric portion W2c, which is in a wrinkled state by being pressed to a position on the upper side of the sewing progress direction Y by the fabric pressing device 8. By blowing air from the air outlet portion 30a of No. 9, the protruding fabric portion W2c is blown to the lower side in the sewing progress direction Y to be transferred, and the succeeding fabric W2 is transferred between the fabric feed belt 7 and the cross plate 4. The fabric feed belt 7 will automatically feed the subsequent fabric W2 even if the sewing manufacturer does not manually feed the fabric W2. Therefore, the continuous sewing work of the tape T on a plurality of fabrics can be easily and smoothly performed.
