　本発明は、ミシンに対してスライドファスナーチェーンとフライ（生地）を搬送し、フライとスライドファスナーチェーンとを縫製して一体にするフライ縫製機に関する。 The present invention relates to a fly sewing machine that transports a slide fastener chain and a fly (fabric) to a sewing machine, and sewes the fly and the slide fastener chain to integrate them.
　上記したフライ縫製機の一例としては、ミシンに対してフライをローラコンベヤで搬送するものが存在する（特許文献１）。フライはミシンに向かって順番に搬送され、一直線に並べられた状態でスライドファスナーチェーンと重なり合って縫製される。 フ ラ イ As an example of the above-mentioned fly sewing machine, there is one that transports a fly to a sewing machine by a roller conveyor (Patent Document 1). The fly is conveyed to the sewing machine in order, and is sewn while overlapping with the slide fastener chain in a state of being aligned.

　しかしながらローラコンベヤはローラを搬送方向に間隔をあけて配置したものなので、フライはその搬送方向の全長における何か所かをローラで押さえられることになる。そうすると、ローラとフライとの接触領域（面積）がフライの搬送方向の全長（全面積）に対して部分的になり、それによってローラがフライに対して滑り（空転し）、フライ（縫製物）の搬送は不安定になる。 し な が ら However, since the roller conveyor has rollers arranged at intervals in the transport direction, the fly can be pressed by the rollers at some point along its entire length in the transport direction. Then, the contact area (area) between the roller and the fly becomes partial with respect to the entire length (total area) in the transport direction of the fly, whereby the roller slides (slips) with respect to the fly, and the fly (sewn) Transport becomes unstable.
　また上記したローラコンベヤによる搬送範囲はミシンに対して上流側である。つまりローラコンベヤによる搬送範囲にミシンの位置は含まれていないので、ミシンに対して上流側の位置とミシンの位置とで搬送が途切れ、縫製物の搬送が不安定になる。 搬 送 The range of conveyance by the roller conveyor is upstream with respect to the sewing machine. That is, since the position of the sewing machine is not included in the transfer range of the roller conveyor, the transfer is interrupted between the position on the upstream side of the sewing machine and the position of the sewing machine, and the transfer of the sewing product becomes unstable.
　本発明は上記実情を考慮して創作されたものであり、その目的は、フライとスライドファスナーチェーンとを縫製して一体にする縫製機において、フライを安定して搬送できるようにすることである。 SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to stably transport a fly in a sewing machine that sewes the fly and a slide fastener chain together. .
　本発明のフライ縫製機は、フライを搬送するフライ搬送装置と、フライ搬送装置で搬送中のフライに向かってスライドファスナーチェーンを搬送するチェーン搬送装置と、フライとスライドファスナーチェーンとを重ね合わせた状態で縫製して一体にするミシンとを備える。フライ搬送装置は、フライを搬送するための３つのベルトコンベヤであって各々のベルトが搬送方向に沿って平行に配置された３つのベルトコンベヤを備える。そして３つのベルトコンベヤは、センターコンベヤと、センターコンベヤに対して両隣に配置される２つのサイドコンベヤである。またセンターコンベヤはミシンに対してその上流側までフライを搬送するものである。そしてサイドコンベヤはミシンに対してその上流側から下流側までフライを搬送するものである。 The fly sewing machine according to the present invention includes a fly transport device that transports the fly, a chain transport device that transports the slide fastener chain toward the fly being transported by the fly transport device, and a state in which the fly and the slide fastener chain are superimposed. And a sewing machine to be integrated with the sewing machine. The fly transport device includes three belt conveyors for transporting a fly, each belt being arranged in parallel along the transport direction. The three belt conveyors are a center conveyor and two side conveyors arranged on both sides of the center conveyor. The center conveyor transports the fly to the upstream side of the sewing machine. The side conveyor transports the fly from the upstream side to the downstream side of the sewing machine.
　またフライはベルトコンベヤのベルトに対し摩擦力によって接するものであり、ベルトに対しできる限り滑らないようにする（搬送状態を安定させる）には次のようにすることが望ましい。
　すなわち、フライ縫製機は、フライを下方側から吸引する吸引装置を備えるものとし、隣り合うベルトコンベヤにおけるベルト同士の間に吸引装置の吸引口を配置してあることが望ましい。 In addition, the fly comes into contact with the belt of the belt conveyor by frictional force, and it is desirable that the fly be as slippery as possible (stabilize the transport state) as follows.
That is, the fly sewing machine is provided with a suction device for sucking the fly from below, and it is preferable that the suction port of the suction device is arranged between the belts of the adjacent belt conveyors.
　またフライ搬送装置は、３つのベルトコンベヤの上方にフライを押さえる装置を備えるか否かは問わないが、フライの搬送を安定させるには次のようにすることが望ましい。
　すなわちフライ搬送装置は、センターコンベヤと協働してフライを一枚挟むことによりフライの重なりを防止する重なり防止装置を備えることである。そして重なり防止装置は、複数のローラと、複数のローラに巻きかけられると共にフライを押さえる押さえベルトとを備えるものとする。また押さえベルトは、センターコンベヤのベルトの上流側に対向して配置されると共に、その下流側の端部にはその隣りに吸引装置の吸引口が配置されているものとする。 The fly transport device may or may not include a device for holding the fly above the three belt conveyors. However, the following is desirable in order to stabilize the transport of the fly.
That is, the fly transport device is provided with an overlap prevention device that prevents fly overlap by sandwiching one fly in cooperation with the center conveyor. The overlap prevention device includes a plurality of rollers and a press belt that is wound around the plurality of rollers and presses the fly. The holding belt is arranged to face the upstream side of the belt of the center conveyor, and the suction port of the suction device is arranged next to the downstream end thereof.
　本発明のフライ縫製機はベルトコンベヤを用いているので、例えばローラコンベヤに比べれば縫製物への接触面積が広くなり、フライの搬送状態が安定するものである。また本発明のフライ縫製機は、ミシンに対してその上流側までのフライの搬送には３つのベルトコンベヤを用いているので、例えば２つのベルトコンベヤを用いるものに比べれば、フライの搬送状態が安定する。また本発明のフライ縫製機は、ミシンに対してその上流側から下流側までを２つのサイドコンベヤで連続して搬送するものなので、例えばミシンに対してその上流側と下流側とで別々に搬送するものや、例えば１つのサイドコンベヤで搬送するものに比べれば、フライの搬送状態が安定する。 (4) Since the fly sewing machine of the present invention uses a belt conveyor, the contact area with the sewn product is larger than that of, for example, a roller conveyor, and the state of transport of the fly is stabilized. Further, the fly sewing machine of the present invention uses three belt conveyors for transporting the fly to the upstream side of the sewing machine. Therefore, compared to a machine using two belt conveyors, for example, the transport state of the fly is reduced. Stabilize. Further, the fly sewing machine of the present invention continuously conveys the sewing machine from the upstream side to the downstream side by two side conveyors. Therefore, for example, the fly sewing machine separately conveys the sewing machine between the upstream side and the downstream side. As compared with a machine that transports a fly, for example, a machine that is transported by one side conveyor, the transport state of the fly is more stable.
　またフライ縫製機は、フライを下方側から吸引する吸引装置を備えるものであれば、隣り合うベルトコンベヤにおけるベルト同士の間に吸引装置の吸引口を配置してあるので、例えば吸引装置のないものに比べれば、フライの搬送状態が安定する。 If the fly sewing machine is provided with a suction device for sucking the fly from below, the suction ports of the suction device are arranged between the belts of the adjacent belt conveyors. In comparison with the above, the transport state of the fly is more stable.
　またフライ縫製機は、重なり防止装置を備えるものであれば、重なり防止装置の押さえベルトとベルトとの間に一枚のフライが挟まれた状態となり、その上で押さえベルトの下流側の端部にはその隣りに吸引口を配置してあるので、フライを一枚ずつ安定して搬送できるようになる。 If the fly sewing machine is equipped with an overlap prevention device, a single fly is sandwiched between the holding belts of the overlap prevention device, and the downstream end of the holding belt is placed on the fly. Has a suction port adjacent to it, so that the fly can be stably transported one by one.

　ベルト２３は、上面が平らなベルトを用いている。なおベルトと言う場合、本実施形態では無端ベルトのことを意味する。
　またベルト２３の一部は、テーブル７の天板７ａの上面において搬送方向に沿って移動可能に支持されている。また当該ベルト２３の一部は、搬送方向に沿って延長している。
　そして３つのベルトコンベヤ２１は、テーブル７の天板７ａの上面において各々のベルト２３を搬送経路の幅方向に間隔をあけて配置してある。またテーブル７の天板７ａの上面には各ベルト２３を案内する溝７ｂが合計で３本形成されている。そして各溝７ｂは、搬送方向に沿って延長するものであり、搬送経路の幅方向に間隔をあけて形成されている。また溝７ｂの上流側の端部と下流側の端部には貫通穴７ｈが形成されている。そして貫通穴７ｈを経てベルト２３を天板７ａの下方から上方に通すようになっている。このようにして３つのベルトコンベヤ２１のベルト２３は、テーブル７の上面において搬送経路に沿って平行に配置されたものとなる。そして溝７ｂにおいて支持されたベルト２３の上面は、搬送経路の一部を形成する。
　そして３つのベルトコンベヤ２１のうち搬送経路の幅方向の関係において中央に配置されたものを「センターコンベヤ」と称し、センターコンベヤ２１Ａに対して両側に配置されたものを「サイドコンベヤ」と称する。なおセンターコンベヤとサイドコンベヤとを区別できるように、センターコンベヤには符号２１Ａを表記し、サイドコンベヤには符号２１Ｂを表記してある。従って３つのベルトコンベヤ２１は、１つのセンターコンベヤ２１Ａと、センターコンベヤ２１Ａに対して両隣に配置される２つのサイドコンベヤ２１Ｂである。 The fly transport device 20 includes three belt conveyors 21 as shown in FIGS. The three belt conveyors 21 have the same basic configuration except for the arrangement. The belt conveyor 21 includes a plurality of rollers 22 disposed below the table 7 a of the table 7. The plurality of rollers 22 include a driving roller 22a and a driven roller 22b. In the present embodiment, the belt conveyor 21 includes a driving roller 22a, a driven roller 22b, and a belt 23 wound around the driving roller 22a and the driven roller 22b.
As the belt 23, a belt having a flat upper surface is used. Note that, in the present embodiment, the term “belt” means an endless belt.
A part of the belt 23 is supported on the upper surface of the top plate 7a of the table 7 so as to be movable along the transport direction. Further, a part of the belt 23 extends along the transport direction.
The three belt conveyors 21 are arranged such that the respective belts 23 are spaced from each other on the upper surface of the top plate 7a of the table 7 in the width direction of the transport path. On the upper surface of the top plate 7a of the table 7, a total of three grooves 7b for guiding each belt 23 are formed. Each groove 7b extends in the transport direction and is formed at intervals in the width direction of the transport path. A through hole 7h is formed at the upstream end and the downstream end of the groove 7b. Then, the belt 23 is passed through the through hole 7h from below the top plate 7a to above. In this way, the belts 23 of the three belt conveyors 21 are arranged in parallel on the upper surface of the table 7 along the transport path. The upper surface of the belt 23 supported in the groove 7b forms a part of the transport path.
Of the three belt conveyors 21, the one arranged at the center in the widthwise relationship of the transport path is referred to as a "center conveyor", and the one arranged on both sides of the center conveyor 21A is referred to as a "side conveyor". In order to distinguish the center conveyor and the side conveyor, the center conveyor is denoted by reference numeral 21A, and the side conveyor is denoted by reference numeral 21B. Therefore, the three belt conveyors 21 are one center conveyor 21A and two side conveyors 21B arranged on both sides of the center conveyor 21A.
　センターコンベヤ２１Ａはミシン４０に対してその上流側までフライ５を搬送するものである。
　サイドコンベヤ２１Ｂはセンターコンベヤ２１Ａに対してその上流端よりも下流側に配置されると共に、ミシン４０に対してその上流側から下流側まで配置される。 The center conveyor 21A transports the fly 5 to an upstream side of the sewing machine 40.
The side conveyor 21B is arranged downstream from the upstream end of the center conveyor 21A, and is arranged from the upstream side to the downstream side of the sewing machine 40.
　また本実施形態のフライ搬送装置２０は、３つのベルトコンベヤ２１の他に、３つのうち少なくとも１つのベルトコンベヤ２１と協働してフライ５を一枚挟むことによりフライ５の重なりを防止する重なり防止装置２５を備える。 In addition, the fly conveying device 20 of the present embodiment cooperates with at least one of the three belt conveyors 21 in addition to the three belt conveyors 21 to sandwich one fly 5 to prevent the fly 5 from overlapping. A prevention device 25 is provided.
　重なり防止装置２５はフライ搬送装置２０の上流側においてベルト２３に対し上方に配置されている。より詳しくは重なり防止装置２５は本実施形態ではセンターコンベヤ２１Ａのベルト２３の上流側に対し上方に対向して配置されている。また搬送方向に関して重なり防止装置２５の上流端は、センターコンベヤ２１Ａの上流端よりも下流側に配置されている。 The overlap prevention device 25 is disposed above the belt 23 on the upstream side of the fly transport device 20. More specifically, in the present embodiment, the overlap prevention device 25 is disposed so as to face upward with respect to the upstream side of the belt 23 of the center conveyor 21A. The upstream end of the overlap prevention device 25 in the transport direction is located downstream of the upstream end of the center conveyor 21A.
　重なり防止装置２５は、複数のローラ２６と、前記複数のローラ２６に巻きかけられると共にフライ５を押さえる押さえベルト２７とを備える。これらローラ２６は本実施形態では従動ローラであるものとする。またローラ２６はフライ供給装置１０のローラ１３と同様に、支持部材１４によって回転可能に支持されているものとする。
　押さえベルト２７は搬送方向に沿って進行する状態でローラ２６に巻きかけられている。また押さえベルト２７は、センターコンベヤ２１Ａのベルト２３に対してその幅方向の中央部に対向して配置される。押さえベルト２７は、その長手方向に対して直交する方向に切断されたときにその断面が円形となるもの、いわゆる丸ベルトである。丸ベルトはゴムであり、弾性変形可能なものである。そして丸ベルトが弾性変形したとしても、重なり防止装置２５の押さえベルト２７（丸ベルト）とセンターコンベヤ２１Ａのベルト２３との間にフライ５が１枚しか入らないように設定されている。その設定には例えば、丸ベルトの弾性変形量、丸ベルトとセンターコンベヤ２１Ａのベルト２３との間隔等が含まれる。
　重なり防止装置２５の押さえベルト２７の設置範囲はサイドコンベヤ２１Ｂのベルト２３に対し、搬送経路の幅方向に関しては離れているが、搬送方向に関しては重複する部分が存在する。より詳しく言えば設置範囲に関して、本実施形態では重なり防止装置２５の押さえベルト２７の下流側の部分はサイドコンベヤ２１Ｂのベルト２３の上流側の部分と重複している。
　上記した重なり防止装置２５の押さえベルト２７とセンターコンベヤ２１Ａのベルト２３とで挟まれたフライ５は、その挟まれた状態のままサイドコンベヤ２１Ｂのベルト２３に搬送される。 The overlap prevention device 25 includes a plurality of rollers 26 and a press belt 27 that is wound around the plurality of rollers 26 and that presses the fly 5. In the present embodiment, these rollers 26 are driven rollers. The roller 26 is rotatably supported by the support member 14, similarly to the roller 13 of the fly supply device 10.
The pressing belt 27 is wound around the roller 26 in a state of proceeding along the transport direction. The pressing belt 27 is disposed so as to face the center of the center conveyor 21A in the width direction with respect to the belt 23. The holding belt 27 is a so-called round belt having a circular cross section when cut in a direction perpendicular to the longitudinal direction. The round belt is rubber and can be elastically deformed. Then, even if the round belt is elastically deformed, only one fly 5 is set between the holding belt 27 (round belt) of the overlap prevention device 25 and the belt 23 of the center conveyor 21A. The settings include, for example, the amount of elastic deformation of the round belt, the distance between the round belt and the belt 23 of the center conveyor 21A, and the like.
The installation range of the pressing belt 27 of the overlap prevention device 25 is distant from the belt 23 of the side conveyor 21B in the width direction of the transport path, but there is an overlapping portion in the transport direction.
