Description

フライ縫製機のフライ搬送装置Fly conveyor for fly sewing machine
　本発明は、フライと称される生地とスライドファスナーチェーンとをミシンで縫製して一体にするフライ縫製機において、ミシンに向かってフライを搬送するフライ搬送装置に関する。 The present invention relates to a fly transport device that transports a fly toward a sewing machine in a fly sewing machine that sewes a fabric called a fly and a slide fastener chain together by a sewing machine.
　従来のフライ縫製機としては、ミシンに向かってフライを無端ベルトで搬送するものが存在する（特許文献１）。そして無端ベルトに対して上方やその近傍には、フライの一部の向きを変える偏向フィンガーや、フライの一部を保持するためのプレッサアーム等が配置されている。 There is a conventional fly sewing machine that conveys the fly toward the sewing machine with an endless belt (Patent Document 1). Further, a deflection finger for changing the direction of a part of the fly, a presser arm for holding a part of the fly, and the like are arranged above and near the endless belt.
　これら偏向フィンガーやプレッサアームは上下動可能になっている。たとえば偏向フィンガーの上端は調整ネジに連結されており、フライ縫製機を厚さの異なるフライに用いる場合、偏向フィンガーの下端部の位置を調整ネジで変えられるようになっている。またプレッサアームの上端も調整ネジに連結されており、プレッサアームの下端部の位置を調整ネジで変えられるようになっている。より詳しく言えば、無端ベルトに対して隣りにプレッサアームとターンテーブルとが上下に対向する状態で配置されており、プレッサアームとターンテーブルとの間に形成される隙間が調整ネジで調整できるようになっている。 These deflection fingers and presser arms can move up and down. For example, the upper end of the deflecting finger is connected to the adjusting screw, and when the fly sewing machine is used for flies having different thicknesses, the position of the lower end of the deflecting finger can be changed by the adjusting screw. The upper end of the presser arm is also connected to the adjusting screw, and the position of the lower end of the presser arm can be changed by the adjusting screw. More specifically, the presser arm and the turntable are arranged vertically adjacent to each other with respect to the endless belt, and the gap formed between the presser arm and the turntable can be adjusted by the adjusting screw. It has become.
　また従来の別のフライ縫製機としては、ミシンに向かってフライをローラで搬送するものが存在する（特許文献２）。これは、フライを搬送する搬送面を上面に有する架台と、搬送面上のフライを下から送り出す駆動ローラと、搬送面上のフライを上から押さえる支持ローラと、支持ローラを駆動ローラに向けて進退自在に支持する上下支持フレームとを備えるものである。そして下側の支持フレームと架台との間に形成される隙間は、図面ではフライを一枚通過させる寸法に設定されている。 Also, as another conventional fly sewing machine, there is one that conveys the fly by rollers toward the sewing machine (Patent Document 2). This consists of a pedestal that has a transport surface for transporting the fly, a drive roller that feeds the fly on the transport surface from below, a support roller that holds the fly on the transport surface from above, and a support roller that faces the drive roller. It is provided with an upper and lower support frame that supports the movable body in a retractable manner. The gap formed between the lower support frame and the pedestal is set to a size that allows one fly to pass through in the drawing.
　ところで変更フィンガーやプレッサアームや下側の支持フレームはフライに対して上側に配置される部品であり、これらの高さ位置はフライの厚みに対応させて適当な位置に設定（調整）するものである。その設定方法は特許文献には記載されていないが、具体的な一例としては以下の通りである。 By the way, the changing fingers, the presser arm, and the lower support frame are parts placed on the upper side of the fly, and their height positions are set (adjusted) to appropriate positions according to the thickness of the fly. is there. Although the setting method is not described in the patent document, a specific example is as follows.
　設定方法の一例はノギスとシックネスゲージを利用する方法である。まずノギスでフライの厚みを測定する。次にシックネスゲージを利用し、リーフと称される金属板を適切な枚数だけプレッサアームとターンテーブルとの隙間に挿入して、その隙間をリーフの厚みから測定する。また隙間に関してはフライの厚みとの関係で経験的に適当と考えられる値、いわゆる経験値が知られている。そして経験値に隙間を一致させるように、調整ネジを回してプレッサアームの高さを設定する。ちなみにシックネスゲージとは、複数枚の厚みの異なるリーフを一まとめにした工具である。 ㆍ One example of the setting method is to use a caliper and thickness gauge. First, measure the thickness of the fly with a caliper. Next, using a thickness gauge, an appropriate number of metal plates called leaves are inserted into the gap between the presser arm and the turntable, and the gap is measured from the thickness of the leaf. Regarding the gap, a value that is considered empirically appropriate in relation to the thickness of the fly, so-called empirical value, is known. Then, turn the adjusting screw to set the height of the presser arm so that the gap matches the experience value. By the way, the thickness gauge is a tool that combines multiple leaves with different thicknesses.
特許２５２９８９４号公報Japanese Patent No. 2529894 特開２００６－１５８７０５号公報JP 2006-158705 A
　ところが上記した設定方法は１）フライの厚みをノギスで測定すること、２）フライを通す隙間をシックネスゲージで測定すること、３）隙間が経験値に一致するように調整ネジを回すこと、の３つの作業をしなければならない。そしてこの設定方法は、ノギスやシックネスゲージという工具を必須とするものであり、作業者の熟練度が調整精度に影響を与えるものである。 However, the setting method described above consists of 1) measuring the thickness of the fly with a caliper, 2) measuring the clearance through which the fly passes with a thickness gauge, and 3) turning the adjusting screw so that the clearance matches the empirical value. You have to do three things. This setting method requires tools such as a caliper and thickness gauge, and the skill level of the operator affects the adjustment accuracy.
　本発明は上記実情を考慮して創作されたものであり、その目的は搬送中のフライに対して上側に配置される部品を、フライの厚みに対応させて適当な位置に設定する作業を容易に行えるようにすることである。 The present invention was created in consideration of the above circumstances, and an object thereof is to facilitate the work of setting a component arranged on the upper side of a fly being transported to an appropriate position in accordance with the thickness of the fly. It is to be able to do it.
　本発明のフライ縫製機のフライ搬送装置は、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ためにミシンに向かってフライを搬送するものである。そして本発明のフライ縫製機のフライ搬送装置は、フライが搬送される搬送面を備えるテーブル、搬送されるフライとは別の調整用フライが搬送面とは異なる位置に載せられる調整プレート、搬送面上のフライを搬送する搬送装置本体、調整プレートとテーブルとの双方に対し上側に配置されると共に搬送装置本体の一部を含む可動ブロック、可動ブロックを上下方向に移動可能に案内するガイド装置を備える。
　また搬送装置本体は、搬送面上のフライに対し上側に配置される上側部材と、搬送面上のフライに対し下側に配置される下側部材とを備える。そして上側部材と下側部材のうち一方はフライを送る送りローラ、他方はフライを押さえる押さえ部材である。
　また可動ブロックは、調整プレートと協働して調整用フライを挟む可動プレート、フライを通過させる間隔を搬送面との間に形成するフライガイド、搬送装置本体のうち上側部材、可動プレートとフライガイドと上側部材とを一体的に接合する接合部材を備える。 The fly conveyor of the fly sewing machine of the present invention conveys the fly toward the sewing machine in order to sew the fly and the slide fastener chain into one piece. Then, the fly transfer device of the fly sewing machine of the present invention includes a table having a transfer surface on which the fly is transferred, an adjusting plate on which an adjustment fly different from the transferred fly is placed at a position different from the transfer surface, and a transfer surface. The main body of the transfer device that transfers the upper fly, the movable block that is arranged above both the adjustment plate and the table and includes a part of the main body of the transfer device, and the guide device that guides the movable block in a vertically movable manner. Prepare
Further, the carrier body includes an upper member arranged above the fly on the carrying surface and a lower member arranged below the fly on the carrying surface. One of the upper member and the lower member is a feed roller that feeds the fly, and the other is a holding member that holds the fly.
Further, the movable block includes a movable plate that cooperates with the adjustment plate to sandwich the adjustment fly, a fly guide that forms a space for passing the fly between the fly and the transport surface, an upper member of the transport device body, the movable plate and the fly guide. And a joining member that integrally joins the upper member with the upper member.
　またガイド装置によって案内された可動ブロックを上下動させるために、昇降する機械（昇降機構）を備えるか否かは問わない。ただし昇降機構を備えない場合には、可動ブロックを手で持ち上げて重力で落下させることになる。そして可動ブロックが手で持ち上げるには重すぎる場合や、可動ブロックが軽すぎて調整用フライを可動プレートと調整プレートとの間に挟んだ状態を保持するには不安定な場合には、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可動ブロックを昇降可能な第１の昇降装置を備えるものとする。そして第１の昇降装置はガイド装置の他に可動ブロックを機械式に昇降する昇降機構部を備えるものとする。 Further, it does not matter whether or not a machine (elevating mechanism) for raising and lowering is provided to vertically move the movable block guided by the guide device. However, if the elevating mechanism is not provided, the movable block is lifted by hand and dropped by gravity. If the movable block is too heavy to lift by hand, or if the movable block is too light and unstable to hold the adjustment fly between the movable plate and the adjustment plate, It is desirable to do so.
That is, the fly transporting device includes a first lifting device that can lift the movable block. In addition to the guide device, the first elevating device includes an elevating mechanism section that mechanically elevates the movable block.
　また昇降機構はどのような機構であるかを問わないが、設定作業を容易にするには次のようにすることが望ましい。
　すなわち第１の昇降装置は、可動ブロックを昇降させるために回転操作する第１の回転操作部と、第１の回転操作部の回転運動を直線運動に変換して可動ブロックを昇降する第１の変換機構部とを備えるものにする。そして第１の回転操作部と第１の変換機構部とは、ガイド装置と昇降機構部とを備えるものである。 Although the lifting mechanism may be any mechanism, it is desirable to do the following to facilitate the setting work.
That is, the first lifting device moves the movable block up and down by moving the movable block by rotating the first rotating operation part and the first rotating operation part. And a conversion mechanism section. The first rotation operation unit and the first conversion mechanism unit include a guide device and a lifting mechanism unit.
　上側部材とフライガイドと接合部材とは可動ブロックを構成するものなので、第１の昇降装置によって一緒に昇降するものであるが、テーブルの搬送面に対する上側部材の高さ位置を最適化するには次のようにすることが望ましい。
　すなわち接合部材は、可動プレートとフライガイドを一体的に接合する主接合部と、主接合部に対して上側部材を昇降可能に連結する第２の昇降装置とを備えることである。 Since the upper member, the fly guide, and the joining member form a movable block, they are lifted and lowered together by the first lifting device, but in order to optimize the height position of the upper member with respect to the transport surface of the table, It is desirable to do the following.
That is, the joining member includes a main joining portion that integrally joins the movable plate and the fly guide, and a second elevating device that connects the upper member to the main joining portion so that the upper member can be moved up and down.
　本発明のフライ搬送装置は、可動プレートとフライガイドと上側部材と接合部材とを一体化したものが可動ブロックなので、従来のような工具を使わなくても、可動プレートと調整プレートとの間に調整用フライを挟持すれば、その挟持する間隔に基づいて（比例して）フライガイドと搬送面との間隔が定まるものである。そして本発明のフライ搬送装置は、可動プレートと調整プレートとを搬送面とは異なる位置に配置してありながら、搬送面とフライガイドとの間に形成される間隔を設定することができるので、調整用フライを挟持したままフライを搬送することができ、しかも可動ブロックを上下動させるだけで、上側部材やフライガイドの高さ位置を設定することができるので、設定作業が容易になるものである。 In the fly transporting device of the present invention, the movable plate, the fly guide, the upper member, and the joining member are integrated into a movable block, so that the movable plate and the adjusting plate are provided between the movable plate and the adjusting plate without using a conventional tool. If the adjustment fly is sandwiched, the space between the fly guide and the transport surface is determined (proportional) based on the sandwiched space. And the fly transporting device of the present invention, since the movable plate and the adjusting plate are arranged at positions different from the transport surface, it is possible to set the interval formed between the transport surface and the fly guide, The fly can be transported while holding the adjustment fly, and the height position of the upper member and the fly guide can be set simply by moving the movable block up and down, which facilitates the setting work. is there.
　また本発明のフライ搬送装置は、ガイド装置の他に可動ブロックを機械式に昇降する昇降機構部を含む第１の昇降装置を備えるものであれば、可動ブロックを手で持ち上げる作業よりも設定作業が容易になるし、重量のみで可動ブロックの下降位置（調整用フライを可動プレートと調整プレートとの間に挟んだ状態）を設定するものに比べれば、可動ブロックの下降位置を安定して保持できる。 Further, the fly transporting device of the present invention is provided with a first elevating device including an elevating mechanism section for mechanically elevating and lowering the movable block, in addition to the guide device, a setting work rather than a work for manually lifting the movable block. This makes it easier to maintain the lower position of the movable block more stable than the one that sets the lower position of the movable block (the condition fly is sandwiched between the movable plate and the adjusting plate) only by weight. it can.
　また本発明のフライ搬送装置は、第１の昇降装置が第１の回転操作部と第１の変換機構部とを備えるものであれば、第１の回転操作部を回転操作するだけで、上側部材やフライガイドの高さ位置を設定することができ、設定作業が容易になる。 Further, in the fly transporting device of the present invention, if the first lifting device includes the first rotation operation part and the first conversion mechanism part, only the first rotation operation part is rotated and the upper side is moved. The height positions of the members and the fly guide can be set, which facilitates the setting work.
　また本発明のフライ搬送装置は、接合部材が第２の昇降装置を備えるものであれば、第１の昇降装置で設定したフライガイドの高さ位置を保持したまま、第２の昇降装置で上側部材の高さ位置をより最適な位置に設定することができる。 In addition, if the joining member is provided with the second lifting device, the fly transporting device of the present invention can be operated by the second lifting device while holding the height position of the fly guide set by the first lifting device. The height position of the member can be set to a more optimal position.

Has been formed. The mover 24c and the female screw member 25 are fitted into the respective through holes, and the mover 24c and the female screw member 25 are fixed to the first joint plate 14e. Since the guide rail 24a is passed through the inside of the mover 24c, the first joining plate 14e and thus the movable block 14 are guided by the guide device 24 so as to be able to move up and down. Since the male screw member 26 is fitted in the female screw member 25 in the state in which the movable block 14 is guided so as to be able to move up and down in this way, the first joining plate 14e and thus the movable block 14 is the first lifting device.

Then, in the first transport unit 13a of the fly transport device 10, the feed roller 13k is driven to rotate intermittently, and the fly 5 sandwiched between the feed roller 13k and the pressing member 13j is fed one by one at a constant timing to the second To the carrying section 13b. By the way, even if two flies 5 overlap each other on the upstream side of the first conveyor 13a and pass between the feed roller 13k and the pressing member 13j, the fly guide 14b and the conveyor 5 may be conveyed on the downstream side of the first conveyor 13a. Only one fly 5 can pass between it and the surface 11a. In the first transport unit 13a, the side surface of the adjusting plate 12 contacts one side of the fly 5 in a rectangular shape, and the fly 5 is transported while being positioned in the width direction of the transport surface 11a (width direction of the fly 5). .

5) In the sewn product conveying device 60, the drive roller is continuously driven to rotate, and the sewn product 8 which is integrated is sent out.
　上記した第一実施形態のフライ縫製機のフライ搬送装置１０は以下の効果を有する。
　フライ搬送装置１０は、可動プレート１４ａとフライガイド１４ｂと上側部材１３ｊ（押さえ部材）と接合部材１４ｃとを一体化したものが可動ブロック１４なので、従来のような工具を使わなくても、可動プレート１４ａと調整プレート１２との間に調整用フライ９を挟持すれば、その挟持する間隔に基づいて（比例して）フライガイド１４ｂと搬送面１１ａとの間隔が定まるものである。そしてフライ搬送装置１０は、可動プレート１４ａと調整プレート１２とを搬送面１１ａとは異なる位置に配置してありながら、搬送面１１ａとフライガイド１４ｂとの間に形成される間隔を設定することができるので、調整用フライ９を挟持したままフライ５を搬送することができ、しかも可動ブロック１４を上下動させるだけで、押さえ部材１３ｊやフライガイド１４ｂの高さ位置を設定することができるので、設定作業が容易になるものである。なおフライ５の種類を変更して、厚みの異なるフライ５をフライ搬送装置１０に対して供給する場合には、フライガイド１４ｂの高さ位置を設定しなければならないが、その設定作業が容易になる。 The fly transfer device 10 of the fly sewing machine according to the first embodiment described above has the following effects.
Since the movable block 14 is the movable plate 14 in which the movable plate 14a, the fly guide 14b, the upper member 13j (pressing member), and the joining member 14c are integrated, the fly transfer device 10 does not require a conventional tool. If the adjusting fly 9 is sandwiched between 14a and the adjusting plate 12, the space between the fly guide 14b and the transport surface 11a is determined (proportionally) based on the sandwiching space. Then, the fly transporting apparatus 10 can set the interval formed between the transport surface 11a and the fly guide 14b while arranging the movable plate 14a and the adjustment plate 12 at positions different from the transport surface 11a. Therefore, the fly 5 can be conveyed while holding the adjusting fly 9, and the height positions of the pressing member 13j and the fly guide 14b can be set only by moving the movable block 14 up and down. This makes setting work easier. When the type of the fly 5 is changed and the fly 5 having different thickness is supplied to the fly transporting device 10, the height position of the fly guide 14b must be set, but the setting work is easy. Become.
　またフライ搬送装置１０は、ガイド装置２４と昇降機構部２８とを含む第１の昇降装置２０を備えるものなので、可動ブロック１４を上下動させるには、第１の昇降装置２０を操作するだけで良く、可動ブロック１４を手で持ち上げる作業よりも、設定作業が容易になる。またフライ搬送装置１０は、第１の昇降装置２０が第１の回転操作部２１と変換機構部２３とを備えるものなので、第１の回転操作部２１を回転操作するだけで、押さえ部材１３ｊやフライガイド１４ｂの高さ位置を設定することができ、設定作業が容易になる。ちなみに可動プレート１４ａと調整プレート１２との間に調整用フライ９を挟んだ状態（可動ブロック１４の下降位置）は、可動ブロック１４の自重に加えて、昇降機構部２８の摩擦抵抗によって保持されるので、安定する。 Further, the fry carrier device 10 includes the first elevating device 20 including the guide device 24 and the elevating / lowering mechanism portion 28. Therefore, in order to move the movable block 14 up and down, only the first elevating device 20 is operated. The setting work is easier than the work of lifting the movable block 14 by hand. Further, in the fry carrier device 10, since the first lifting device 20 includes the first rotation operation portion 21 and the conversion mechanism portion 23, only by rotating the first rotation operation portion 21, the pressing member 13j or the pressing member 13j can be operated. The height position of the fly guide 14b can be set, which facilitates the setting work. Incidentally, the state in which the adjusting fly 9 is sandwiched between the movable plate 14a and the adjusting plate 12 (the lowered position of the movable block 14) is held by the frictional resistance of the lifting mechanism unit 28 in addition to the own weight of the movable block 14. So be stable.
　またフライ搬送装置１０は、接合部材１４ｃが第２の昇降装置３０を備えるものなので、第１の昇降装置２０で設定したフライガイド１４ｂの高さ位置を保持したまま、第２の昇降装置３０で押さえ部材１３ｊの高さ位置をより最適な位置に設定することができる。しかも第２の昇降装置３０が第２の回転操作部３１と第２の変換機構部３２とを備えるものなので、第２の回転操作部３１を回転操作するだけで、押さえ部材１３ｊの高さ位置を設定することができるので、設定作業が容易になる。 Further, since the joining member 14c of the fry carrier device 10 includes the second elevating device 30, the second elevating device 30 holds the height position of the fly guide 14b set by the first elevating device 20. The height position of the pressing member 13j can be set to a more optimal position. Moreover, since the second elevating device 30 includes the second rotation operating portion 31 and the second conversion mechanism portion 32, only by rotating the second rotation operating portion 31, the height position of the pressing member 13j can be adjusted. Can be set, which facilitates the setting work.
