Description
【０００１】[0001]
この考案は、自動ワインダー等においてボビンをトレーに挿着した状態で搬送 する過程でボビンの糸層の有無を検出する残糸検出装置に関するものである。 The present invention relates to a residual thread detecting device for detecting the presence or absence of a thread layer on a bobbin in the process of transporting the bobbin in a tray attached to an automatic winder or the like.
【０００２】[0002]
残糸検出装置として、従来、光学タイプのものが知られている。その残糸検出 装置は、投光部と受光素子とよりなる反射式光センサーをトレー搬送路に向けて 配置したものである。 An optical type is conventionally known as a residual thread detecting device. The residual yarn detecting device is one in which a reflection type optical sensor consisting of a light projecting section and a light receiving element is arranged toward the tray transport path.
【０００３】[0003]
上記の残糸検出装置は、装置そのものが高価であるばかりでなく、ボビンと糸 との色との差が無い場合には判別が困難であるし、糸の色が変わると検出が不安 定となるので、その都度レベル調整をしなければならない。また、糸の色が異な るボビンを同時に扱うことも不可能である。 The above-mentioned residual thread detecting device is not only expensive in itself but also difficult to discriminate if there is no difference in color between the bobbin and the thread, and if the color of the thread changes, the detection becomes unstable. Therefore, you have to adjust the level each time. It is also impossible to handle bobbins with different thread colors at the same time.
【０００４】 この考案は、構造が簡単であり、且つ、信頼性の高い残糸検出装置を提供する ことを目的としている。An object of the present invention is to provide a residual yarn detection device having a simple structure and high reliability.
【０００５】[0005]
上記目的を達成するために、この考案の残糸検出装置は、先端にブラシが植設 され基端が水平支軸に回動可能に支持された残糸検出レバーと、その下側に当接 して上下動する操作部材と、残糸検出レバーが正方向に所定以上回動したことを 検出する検出手段とよりなるものである。 In order to achieve the above-mentioned object, a residual thread detecting device of the present invention comprises a residual thread detecting lever having a brush implanted at its tip and a base end rotatably supported by a horizontal support shaft, and an abutting portion below the lever. Then, it comprises an operation member that moves up and down, and a detection means that detects that the residual thread detection lever has rotated in the forward direction by a predetermined amount or more.
【０００６】[0006]
上記のように構成された残糸検出装置においては、ボビンを挿着したトレイが 止められると、操作部材が下降し、残糸検出レバーは自重で下方に回動する。そ の際、ボビンに残糸があれば、ブラシが残糸に引っ掛かり、残糸検出レバーはそ の位置で止まり、検出手段から残糸有りの信号が出される。また、ボビンに残糸 がなければ、残糸検出レバーは下限位置まで揺動し、検出手段から残糸なしの信 号が出される。 In the residual thread detecting device configured as described above, when the tray on which the bobbin is inserted is stopped, the operating member descends and the residual thread detecting lever rotates downward by its own weight. At this time, if there is residual thread on the bobbin, the brush is caught by the residual thread, the residual thread detection lever stops at that position, and the detection means outputs a signal indicating that there is residual thread. If there is no residual thread on the bobbin, the residual thread detection lever swings to the lower limit position, and the detection means outputs a signal indicating no residual thread.

図１及び図２を参照し、この考案の残糸検出装置について説明する。 The residual yarn detecting device of the present invention will be described with reference to FIGS. 1 and 2.
【０００８】 先ず、この考案のボビンの残糸検出装置が採用される精紡機と自動ワインダー の連結システムについて説明する。First, a connecting system of a spinning machine and an automatic winder in which the bobbin residual yarn detecting device of the present invention is adopted will be described.
【０００９】 このシステムは、精紡管糸（以後、実ボビンということもある）を生産する多 数錘からなる精紡機Ｓと精紡管糸を巻き返す自動ワインダーＷとの間をボビンを トレーに挿着した状態で循環させるものであり、自動ワインダーＷ内には、多数 錘のワインディングユニットからなるワインダー本体１と、精紡管糸の糸端を口 出しするための周知の口出装置２とが設けられている。これらの間のトレイの移 動は、各部分を巡る移送路によってなされる。This system uses a bobbin as a tray between a spinning machine S, which is made up of multiple spindles for producing spinning yarn (hereinafter sometimes referred to as an actual bobbin), and an automatic winder W that rewinds the spinning yarn. The automatic winder W is circulated in a state in which it is inserted, and a winder body 1 composed of a winding unit with a large number of weights, and a well-known spouting device 2 for spouting the yarn end of a spinning tube yarn. Is provided. The movement of the tray between these is done by the transfer path around each part.
【００１０】 移送路は、精紡機Ｓより自動ワインダーＷに延びる搬入路Ｌ1 と、その延長に あり、ワインダー本体１の長手方向に沿って循環形成された導入路Ｌ2 と、ワイ ンダー本体１の各錘から巻き尽くされたボビンを挿着する空トレイを排出する排 出路Ｌ3 と、各排出路Ｌ3 から排出される空トレイを精紡機Ｓ側へ運ぶ搬出路Ｌ 4 と、口出装置２で糸端の口出しミスをした実ボビンを再度口出装置２に戻す循 環路Ｌ5 とよりなっている。The transfer path is a carry-in path L extending from the spinning machine S to the automatic winder W.1And the introduction path L which is formed in the extension thereof and is circulated along the longitudinal direction of the winder body 1.2And the discharge path L for discharging the empty tray into which the bobbin wound around each weight of the winder body 1 is inserted.3And each discharge path L3Carry-out route L for carrying the empty tray discharged from the spinning machine S side Four And the circulation path L for returning the actual bobbin for which the yarn end is missed in the yarn feeder 2 to the yarn feeder 2 again.FiveIt has become.
【００１１】 搬出路Ｌ4 を移動するトレイに挿着のボビンに残糸がある場合には、ボビンス トリッパー３によって残糸が取り除かれ、空ボビンにして精紡機Ｓに返される。 また、搬出路Ｌ4 を移動するトレイに挿着のボビンに３分玉以上糸が残っている 場合には、循環路Ｌ5 より再度口出装置２に戻される。When the bobbin inserted into the tray moving on the carry-out path L 4 has residual yarn, the bobbin stripper 3 removes the residual yarn and returns it to the spinning machine S as an empty bobbin. Further, when there is a yarn remaining for more than 3 minutes on the bobbin inserted into the tray moving on the carry-out path L 4 , it is returned to the dispensing device 2 again from the circulation path L 5 .
【００１２】 この考案の残糸検出装置は、ボビンストリッパー３における残糸除去に先立っ てボビンの残糸の有無を検査するもので、図２に符号Ａで示す搬出路Ｌ4 の下流 端に設けられる。The residual thread detecting device of the present invention is for inspecting the presence or absence of residual thread in the bobbin before removing the residual thread in the bobbin stripper 3, and is provided at the downstream end of the carry-out path L 4 shown by reference character A in FIG. To be
【００１３】 この残糸検出装置は、先端に残糸検出ブラシ５が植設され、基端が水平支軸６ に回動可能に支持された残糸検出レバー４と、残糸検出レバー４の下側に当接し 、エアーシリンダー８によって上下動する操作ピン７と、残糸検出レバー４の揺 動下限位置に設けられた近接スイッチ９と、残糸検出レバー４が揺動上限位置に あるときに残糸検出ブラシ５にエアーを噴出するノズル１０とより構成されてい る。In this residual thread detecting device, a residual thread detecting brush 5 is planted at the tip, and the proximal end of the residual thread detecting lever 4 is rotatably supported by a horizontal support shaft 6 and the residual thread detecting lever 4. When the operating pin 7 that comes into contact with the lower side and moves up and down by the air cylinder 8, the proximity switch 9 provided at the lower swing limit position of the residual thread detection lever 4, and the residual thread detection lever 4 at the upper swing position And a nozzle 10 for ejecting air to the residual yarn detection brush 5.
【００１４】 水平支軸６には、ベアリング１３を介してボス１４が回動可能に取り付けられ ており、残糸検出レバー４は、基端がそのボス１４に挿入され、セットボルト１ ５によりボス１４に固定されている。A boss 14 is rotatably attached to the horizontal support shaft 6 via a bearing 13. The residual thread detection lever 4 has a base end inserted into the boss 14 and a boss 14 by a set bolt 15. It is fixed at 14.
【００１５】 残糸検出レバー４は、近接スイッチ９に反応する金属製の棒体であり、残糸検 出ブラシ５は、弾性のある金属線等の丈夫なものが用いられる。この残糸検出レ バー４は、搬出路Ｌ4 のＡ位置に不図示のストッパーによって止められたトレイ Ｔに挿着されたボビンＢの上流側面に沿ってすれすれに回動する位置に設置され ている。残糸検出ブラシ５の向きは、残糸検出レバー４の下方への回動時にボビ ンＢの上流側面に積極的に触れるよう、若干ボビンＢ側に傾けて突出するように する。The residual thread detection lever 4 is a rod made of metal that reacts with the proximity switch 9, and the residual thread detection brush 5 is made of a durable material such as an elastic metal wire. The residual thread detection lever 4 is installed at a position where it can smoothly rotate along the upstream side surface of the bobbin B inserted into the tray T which is stopped by a stopper (not shown) at the position A of the carry-out path L 4. There is. The orientation of the residual thread detecting brush 5 is set so as to slightly incline toward the bobbin B side so as to positively contact the upstream side surface of the bobbin B when the residual thread detecting lever 4 is rotated downward.
【００１６】 操作ピン７は、ブラケット１１を介してエアーシリンダー８のロッド８ａに取 付けられており、トレイＴがＡ位置に進入し、ストッパーにより止められたとき にロッド８ａが急速に伸びることにより、下降する。また、ストッパーを解除し たときに、ロッド８ａが伸縮することにより、上昇する。The operation pin 7 is attached to the rod 8a of the air cylinder 8 via the bracket 11, and when the tray T enters the position A and is stopped by the stopper, the rod 8a rapidly extends. , Descend. Further, when the stopper is released, the rod 8a expands and contracts to rise.
【００１７】 なお、エアーシリンダー８の代わりに、ロータリーソレノイドを用いることも 可能であるが、ロータリーソレノイドは、エアーシリンダーに比べて動作速度が 非常に遅い欠点がある。また、ロータリーソレノイドの設置には大きな空間が必 要であるので、余裕のある離れた位置に置かねばならず、そのため残糸検出レバ ー４をかなりの長さにしなければならない。更に、ロータリーソレノイドは、一 方向のみの駆動であるので、残糸検出レバー４を復帰させるために別途バネ等を 設けねばならず、復帰力が弱くなる。そのため、残糸検出レバー４の復帰時に糸 に引っ掛かって復帰しないことがあるが、この実施例ではエアーシリンダー８に より残糸検出レバー４を強制的に復帰させるので、上記の問題は生じない。It is possible to use a rotary solenoid instead of the air cylinder 8, but the rotary solenoid has a drawback that its operating speed is very slow compared to the air cylinder. Also, since the installation of the rotary solenoid requires a large space, it must be placed in a distant position with a margin, and therefore the residual thread detection lever 4 must be made considerably long. Furthermore, since the rotary solenoid is driven only in one direction, a spring or the like must be additionally provided in order to return the residual thread detecting lever 4, and the return force becomes weak. Therefore, when the residual thread detecting lever 4 is returned, it may be caught by the thread and may not be recovered, but in this embodiment, the residual thread detecting lever 4 is forcibly returned by the air cylinder 8, so the above problem does not occur.
【００１８】 エアー噴出ノズル１０は、ロッド８ａの伸縮終了時、即ち、操作ピン７が上昇 して残糸検出レバー４が揺動上限位置にきたときに、一定時間エアーを噴出して 残糸検出ブラシ５に付着している風綿を除去するものである。The air ejection nozzle 10 ejects air for a certain period of time to detect residual thread when the expansion and contraction of the rod 8a is completed, that is, when the operation pin 7 is lifted and the residual thread detection lever 4 reaches the swing upper limit position. The cotton wool adhering to the brush 5 is removed.
【００１９】 このように構成された残糸検出装置において、巻取りが終了して自動ワインダ ーＳのワインディングユニットから排出路Ｌ3 へ放出されるボビンＢを挿着した トレイＴが搬出路Ｌ4 を移動してＡ位置にやってき、ストッパーにより止められ ると、エアーシリンダー８のロッド８ａが急速に伸びて操作ピン７が下降し、残 糸検出レバー４は支えを失って自重で下方に回動する。その際、ボビンＢに残糸 １２があれば、残糸検出ブラシ５が残糸１２に引っ掛かり、残糸検出レバー４は その位置で止まる。従って、近接スイッチ９は残糸検出レバー４を検出せず、残 糸有りの信号を出し、そのボビンＢがボビンストリッパー３の位置にやってきた ときに、そこで残糸１２が除去される。また、ボビンＢに残糸１２がなければ、 残糸検出レバー４は下限位置まで揺動する。従って、近接スイッチ９は残糸検出 レバー４を検出し、残糸なしの信号が出され、そのボビンＢはボビンストリッパ ー３の位置を素通りする。In the residual yarn detecting device configured as described above, the tray T, into which the bobbin B discharged from the winding unit of the automatic winder S and discharged to the discharge path L 3 is inserted, is taken out from the discharge path L 4 Is moved to the position A and stopped by the stopper, the rod 8a of the air cylinder 8 expands rapidly and the operation pin 7 descends, and the residual thread detection lever 4 loses its support and rotates downward by its own weight. To do. At this time, if the bobbin B has the residual yarn 12, the residual yarn detecting brush 5 is caught by the residual yarn 12, and the residual yarn detecting lever 4 stops at that position. Therefore, the proximity switch 9 does not detect the residual thread detecting lever 4, outputs a signal indicating that there is a residual thread, and when the bobbin B comes to the position of the bobbin stripper 3, the residual thread 12 is removed there. If there is no residual thread 12 on the bobbin B, the residual thread detection lever 4 swings to the lower limit position. Therefore, the proximity switch 9 detects the residual thread detecting lever 4, a signal indicating that there is no residual thread is output, and the bobbin B passes through the position of the bobbin stripper 3.

この考案は、以上説明したように構成されているので、以下に記載するような 効果を奏する。 Since the present invention is configured as described above, it has the following effects.
【００２１】 即ち、巻かれている糸がどのような色のボビンであっても何ら調整を要するこ となく確実に残糸を検出することができる。また、構造が簡単であるので製造コ ストも低減することができる。更に、操作ピンの駆動手段としてエアーシリンダ ーを用いる場合には、残糸検出速度を速くすることができ、装置全体の小型化が 可能となる。That is, no matter what color the bobbin is wound on, the remaining yarn can be reliably detected without any adjustment. Further, since the structure is simple, the manufacturing cost can be reduced. Furthermore, when an air cylinder is used as the drive means for the operation pin, the residual yarn detection speed can be increased, and the overall size of the device can be reduced.
