Description

この発明は、リング精紡機の不正ドッフィング検出装置に関する。 The present invention relates to an illegal doffing detection device for a ring spinning machine.

精紡機のドッフィング処理において、不正ドッフィングが発生した場合には、これを検出して適宜対応することが必要となる。特許文献１には、スピンドルからのボビンの抜き取り失敗を検出するための構成が記載されている。特許文献１の構成では、ボビンの抜き取り失敗が検出された場合には、作業員が抜き取り失敗のあった場所を探し、その場所に移動した後に満管糸をスピンドルから引き抜く。 In the doffing process of the spinning frame, if illegal doffing occurs, it is necessary to detect it and take appropriate measures. Japanese Patent Laid-Open No. 2002-200002 describes a configuration for detecting a failure in removing a bobbin from a spindle. In the configuration of Patent Document 1, when a bobbin pull-out failure is detected, an operator searches for the place where the pull-out failure occurred, moves to that place, and then pulls out the full bobbin yarn from the spindle.

特公昭４８－３３３９号公報Japanese Patent Publication No. 48-3339

しかしながら、従来技術では、不正ドッフィングが発生した場所を特定するために時間がかかるという問題があった。たとえば、特許文献１の構成では、不正ドッフィングが発生したスピンドル列までは自動的に特定できるが、そのスピンドル列のどのスピンドルが不正ドッフィングを起こしたかは作業員が特定する必要がある。 However, the prior art has the problem that it takes time to identify the location where illegal doffing occurs. For example, in the configuration of Patent Document 1, the row of spindles in which illegal doffing has occurred can be automatically identified, but an operator must identify which spindle in that spindle row has caused illegal doffing.

この発明はこのような問題点を解消するためになされたものであり、リング精紡機において不正ドッフィングが発生した場所をより容易に特定できる、不正ドッフィング検出装置を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a fraudulent doffing detector that can more easily identify the location where fraudulent doffing occurs in a ring spinning machine.

実施の形態１．
図１に、この発明の実施の形態１に係る、リング精紡機の不正ドッフィング検出装置を含む構成の例を示す。不正ドッフィング検出装置は、１台以上のリング精紡機１０に関連して設けられる。なお、リング精紡機１０は図示のように複数台が整列して配置されていると好適であるが、１台のみであっても、または整列されていなくとも、本発明は実施可能である。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
Embodiment 1.
FIG. 1 shows an example of a configuration including an illegal doffing detection device for a ring spinning machine according to Embodiment 1 of the present invention. A fraudulent doffing detection device is provided in connection with one or more ring spinning machines 10 . Although it is preferable that a plurality of ring spinning machines 10 are arranged in line as shown in the drawing, the present invention can be practiced with only one ring spinning machine or with no arrangement.

本実施形態では、不正ドッフィング検出装置は情報処理装置２０および携帯端末３０を備える。情報処理装置２０はたとえば公知のコンピュータを用いて構成することができ、演算手段および記憶手段を備える。情報処理装置２０はさらに通信手段を備えており、リング精紡機１０に関連して設けられる機器との間および携帯端末３０との間で情報の送受信を行うことができる。 In this embodiment, the illegal doffing detection device includes an information processing device 20 and a mobile terminal 30 . The information processing device 20 can be configured using, for example, a known computer, and includes computing means and storage means. The information processing device 20 further includes communication means, and can transmit and receive information to and from devices provided in relation to the ring spinning machine 10 and to and from the portable terminal 30 .

携帯端末３０は、個人が携帯することが可能なコンピュータを用いて構成することができ、演算手段および記憶手段を備える。携帯端末３０はさらに通信手段を備えており、情報処理装置２０との間で情報の送受信を行うことができる。携帯端末３０はスマートフォンまたはウェアラブルコンピュータであってもよい。本実施形態では、携帯端末３０が出力部を構成し、不正ドッフィングが発生した錘の位置を出力する。 The mobile terminal 30 can be configured using a computer that can be carried by an individual, and has computing means and storage means. The mobile terminal 30 further includes communication means, and can transmit and receive information to and from the information processing device 20 . Mobile terminal 30 may be a smart phone or a wearable computer. In this embodiment, the mobile terminal 30 constitutes an output unit, and outputs the position of the weight at which illegal doffing has occurred.

図２に、リング精紡機１０の構成の例を示す。リング精紡機１０は、錘１１と、糸切れセンサ１２と、糸切れ表示ランプ１３とを備える。糸切れセンサ１２は糸切れ検出部を構成し、錘１１毎に設けられる。また、本実施形態では、糸切れ表示ランプ１３も錘１１毎に設けられる。 FIG. 2 shows an example of the configuration of the ring spinning machine 10. As shown in FIG. The ring spinning machine 10 includes a weight 11 , a yarn breakage sensor 12 and a yarn breakage indicator lamp 13 . The yarn breakage sensor 12 constitutes a yarn breakage detection section and is provided for each weight 11 . In addition, in the present embodiment, a yarn break indicator lamp 13 is also provided for each weight 11 .

図３に、錘１１および糸切れセンサ１２の構成の例を示す。糸切れセンサ１２は、対応する錘１１が糸切れ状態であるか、または非糸切れ状態であるかを決定するための情報を取得する。リング精紡機１０には支持部材８０（たとえばスピンドルレール）が取り付けられ、支持部材８０にはスピンドル５０が固定される。ボビン６０がスピンドル５０に挿入され、スピンドル５０および支持部材８０によって支持される。ボビン６０はその底部に尻金６０ａを備える。リング精紡機１０の運転期間内において、尻金６０ａの上方、ボビン６０の周囲に、管糸７０が巻き付けられてゆく。 FIG. 3 shows an example of the configuration of the weight 11 and the yarn breakage sensor 12. As shown in FIG. The thread breakage sensor 12 acquires information for determining whether the corresponding weight 11 is in the thread breakage state or in the non-thread breakage state. A support member 80 (for example, a spindle rail) is attached to the ring spinning machine 10 , and the spindle 50 is fixed to the support member 80 . A bobbin 60 is inserted into spindle 50 and supported by spindle 50 and support member 80 . The bobbin 60 has a tail metal 60a at its bottom. During the operation of the ring spinning machine 10, the cop yarn 70 is wound around the bobbin 60 above the tail metal 60a.

糸切れセンサ１２は、本実施形態では光学式センサを備える。図３においてグレーで示した領域が、糸切れセンサ１２の視野である（後述の図５および図６について同じ）。糸切れセンサ１２は、たとえばこの視野内に投光し、糸又はトラベラからの反射光の光量変化に基づき、錘１１の糸切れを検知する。糸切れを検知するための方法および具体的構成はとくに説明しないが、たとえば特表２００５－５３５７９４に記載されるようにトラベラを検知するものであってもよいし、特開平９－１８８９２３に記載されるようにバルーニングした糸の有無を検知するものであってもよい。 The yarn breakage sensor 12 is provided with an optical sensor in this embodiment. The area shown in gray in FIG. 3 is the field of view of the yarn breakage sensor 12 (the same applies to FIGS. 5 and 6 described later). The yarn breakage sensor 12 emits light within this field of view, for example, and detects yarn breakage of the weight 11 based on changes in the amount of light reflected from the yarn or the traveler. Although the method and specific configuration for detecting yarn breakage will not be particularly described, for example, a traveler may be detected as described in JP-A-9-188923. The presence or absence of the ballooned yarn may be detected.

糸切れセンサ１２が糸切れを検知した場合のリング精紡機１０等の動作については、どのようなものであってもよいが、たとえば、糸切れ表示ランプ１３が糸切れセンサ１２からの信号に応じて点灯するように構成してもよい。 Any operation of the ring spinning machine 10 or the like when the yarn breakage sensor 12 detects the yarn breakage may be performed. It may be configured to light up when

なお、本実施形態において、糸切れセンサ１２の視野には、管糸７０またはボビン６０の少なくとも一部が含まれる。図３の例では管糸７０の一部が含まれている。 In this embodiment, the field of view of the yarn breakage sensor 12 includes at least part of the cop 70 or the bobbin 60 . A portion of the cop 70 is included in the example of FIG.

図４に、情報処理装置２０の構成の例を示す。情報処理装置２０は判定部２１を備える。判定部２１は、情報処理装置２０の演算手段および記憶手段が、記憶手段に記憶されたプログラムに従って協働することによって実現される。 FIG. 4 shows an example of the configuration of the information processing device 20. As shown in FIG. The information processing device 20 includes a determination section 21 . Determining unit 21 is realized by cooperation between the computing means and the storage means of information processing apparatus 20 according to a program stored in the storage means.

情報処理装置２０は、リング精紡機１０の動作を制御または監視し、各リング精紡機１０がドッフィング期間にあるか、または非ドッフィング期間（たとえば運転期間）にあるかを認識する。ドッフィング期間とは、リング精紡機１０が錘１１のドッフィング処理を実行する処理を含む期間をいう。ドッフィング処理は、各錘１１のスピンドル５０に対して、まず管糸（満管糸または満管ボビン）を抜き取り、その後に、ボビン（空ボビン）を挿入するという動作を含む。このように、ドッフィング期間は、管糸抜き取り処理のタイミングと、ボビン挿入処理のタイミングとを含むということができる。 The information processing device 20 controls or monitors the operation of the ring spinning frame 10 and recognizes whether each ring spinning frame 10 is in a doffing period or a non-doffing period (for example, an operating period). The doffing period is a period including the process of performing the doffing process of the spindle 11 by the ring spinning frame 10 . The doffing process includes an operation of first removing the winding yarn (full yarn or full bobbin) from the spindle 50 of each weight 11 and then inserting the bobbin (empty bobbin). In this way, it can be said that the doffing period includes the timing of the thread winding processing and the timing of the bobbin insertion processing.

本実施形態では、ドッフィング期間内では糸切れ検知を行う必要はない。すなわち、糸切れセンサ１２は、リング精紡機１０の運転期間の少なくとも一部においては糸切れを検出するためのセンサとして機能するものであるが、他の期間（たとえばドッフィング期間）においては、糸切れを検出するためのセンサとして機能する必要はない。 In this embodiment, it is not necessary to detect yarn breakage during the doffing period. That is, the yarn breakage sensor 12 functions as a sensor for detecting yarn breakage during at least part of the operation period of the ring spinning machine 10, but during other periods (for example, the doffing period), the yarn breakage sensor 12 functions as a sensor for detecting yarn breakage. need not function as a sensor to detect

判定部２１は、ドッフィング期間内における糸切れセンサ１２の信号変動に基づいて、不正ドッフィングの有無を判定する。本実施形態では、糸切れセンサ１２のそれぞれから出力される映像信号または光量信号に基づいて、判定が行われる。また、本実施形態では、リング精紡機１０の動作に対応したタイミングで判定が行われる。たとえば、判定部２１は、スピンドル５０に対する管糸抜き取り処理のタイミングと、スピンドル５０に対するボビン挿入処理のタイミングとにおいて、それぞれ不正ドッフィングの有無を判定する。 The judging section 21 judges the presence or absence of illegal doffing based on the signal fluctuation of the yarn breakage sensor 12 during the doffing period. In this embodiment, the determination is made based on the video signal or the light amount signal output from each of the thread breakage sensors 12 . Further, in the present embodiment, determination is made at timing corresponding to the operation of the ring spinning machine 10 . For example, the determination unit 21 determines whether or not there is illegal doffing at the timing of the process of removing the bobbin thread from the spindle 50 and the timing of the process of inserting the bobbin into the spindle 50 .

以下、図５および図６を用いて、判定のより詳細な具体例について説明する。
図５は、ドッフィング処理のうち管糸抜き取り処理時の判定について説明する図である。このタイミングでの不正ドッフィング判定は、管糸抜き取り失敗判定である。
図５（ａ）は、管糸抜き取り処理の開始前の状態を示す。糸切れセンサ１２の視野に管糸７０の一部が存在しており、糸切れセンサ１２はこの状態を検出して信号を出力する。判定部２１はこの信号を受信し、管糸７０が視野内に存在していることを認識する。 A more detailed specific example of the determination will be described below with reference to FIGS. 5 and 6. FIG.
5A and 5B are diagrams for explaining the determination in the doffing process during the process of extracting the cob yarn. The determination of improper doffing at this timing is the determination of unsuccessful removal of the bobbin thread.
FIG. 5(a) shows the state before the start of the process of removing the bobbin thread. A portion of the bobbin thread 70 exists in the field of view of the yarn breakage sensor 12, and the yarn breakage sensor 12 detects this state and outputs a signal. The judging section 21 receives this signal and recognizes that the cop 70 exists within the field of view.

判定部２１による認識処理の内容は任意に設計可能であるが、たとえば画像処理によって管糸７０を表す領域を検出する処理を用いてもよいし、視野内の光量が所定の閾値以上かどうかを判定する処理を用いてもよい。検出すべき領域の色および光量の比較方法は、管糸７０の色等に応じて設計可能である。以下、判定部２１による認識処理について同様である。 The contents of the recognition processing by the determination unit 21 can be arbitrarily designed. You may use the process to determine. The method of comparing the color of the area to be detected and the amount of light can be designed according to the color of the cop yarn 70 and the like. The same applies to the recognition processing by the determination unit 21 below.

図５（ｂ）は、管糸抜き取り処理が進行中である状態を示す。ボビン６０（およびこれに巻き付けられた管糸７０）が矢印の方向に移動してゆく。この移動につれて、糸切れセンサ１２の信号が変動する。 FIG. 5(b) shows a state in which the process of removing the bobbin thread is in progress. The bobbin 60 (and the cop 70 wound thereon) moves in the direction of the arrow. Along with this movement, the signal of the yarn breakage sensor 12 fluctuates.

図５（ｃ）は、管糸抜き取り処理が完了した状態を示す。糸切れセンサ１２の視野には管糸７０はもはや存在しておらず、糸切れセンサ１２はこの状態を検出して信号を出力する。判定部２１はこの信号を受信し、管糸７０が視野内に存在していないことを認識する。 FIG. 5(c) shows a state in which the process of removing the cop is completed. The bobbin yarn 70 no longer exists in the field of view of the yarn breakage sensor 12, and the yarn breakage sensor 12 detects this state and outputs a signal. The judging section 21 receives this signal and recognizes that the bobbin thread 70 does not exist within the field of view.

このように、管糸抜き取り処理の前後で、管糸７０が視野内に存在している状態から、管糸７０が視野内に存在していない状態へと遷移した場合に、判定部２１は、ドッフィング処理が正常に終了した（すなわち不正ドッフィングは発生していない）と判定する。より具体的には、糸切れセンサ１２の信号が、管糸７０（またはその一部）の存在を示す状態から、管糸７０（またはその一部）の存在を示さない状態へと変動した場合に、判定部２１は、ドッフィング処理が正常に終了した（すなわち不正ドッフィングは発生していない）と判定する。 As described above, when the state in which the thread 70 exists in the field of view changes to the state in which the thread 70 does not exist in the field of view before and after the process of extracting the thread , the determination unit 21 It is determined that the doffing process has ended normally (that is, no illegal doffing has occurred). More specifically, when the signal from the yarn breakage sensor 12 changes from a state indicating the presence of the cop yarn 70 (or a portion thereof) to a state not indicating the presence of the cop yarn 70 (or a portion thereof). Then, the determination unit 21 determines that the doffing process has ended normally (that is, no illegal doffing has occurred).

そうでない場合には、判定部２１は、ドッフィング処理が正常に終了しなかった（すなわち不正ドッフィングが発生した）と判定する。このようなケースは、たとえば、ボビン６０が正しく抜き取られずスピンドル５０に挿入されたままとなっており、したがって管糸７０の一部が糸切れセンサ１２の視野内に留まっているような場合に発生する。 Otherwise, the determination unit 21 determines that the doffing process did not end normally (that is, illegal doffing occurred). Such a case occurs, for example, when the bobbin 60 is not removed correctly and remains inserted in the spindle 50, so that part of the cop yarn 70 remains within the field of view of the yarn breakage sensor 12. do.

図６は、ドッフィング処理のうちボビン挿入処理時の判定について説明する図である。このタイミングでの不正ドッフィング判定は、ボビン挿入失敗判定である。
図６（ａ）は、ボビン挿入処理の開始前の状態を示す。糸切れセンサ１２の視野にはボビン６０は存在しておらず、糸切れセンサ１２はこの状態を検出して信号を出力する。判定部２１はこの信号を受信し、ボビン６０が視野内に存在していないことを認識する。 FIG. 6 is a diagram for explaining determination during the bobbin insertion process in the doffing process. Incorrect doffing determination at this timing is bobbin insertion failure determination.
FIG. 6(a) shows the state before the start of the bobbin insertion process. The bobbin 60 does not exist in the field of view of the yarn breakage sensor 12, and the yarn breakage sensor 12 detects this state and outputs a signal. The determination unit 21 receives this signal and recognizes that the bobbin 60 does not exist within the field of view.

図６（ｂ）は、ボビン挿入処理が進行中である状態を示す。尻金６０ａを備えるボビン６０が矢印の方向に移動してゆく。この移動につれて、糸切れセンサ１２の信号が変動する。 FIG. 6(b) shows a state in which the bobbin insertion process is in progress. A bobbin 60 having a tail metal 60a moves in the direction of the arrow. Along with this movement, the signal of the yarn breakage sensor 12 fluctuates.

図６（ｃ）は、ボビン挿入処理が完了した状態を示す。糸切れセンサ１２の視野にはボビン６０が存在しており、糸切れセンサ１２はこの状態を検出して信号を出力する。判定部２１はこの信号を受信し、ボビン６０が視野内に存在していることを認識する。 FIG. 6(c) shows a state in which the bobbin insertion process has been completed. The bobbin 60 exists in the field of view of the yarn breakage sensor 12, and the yarn breakage sensor 12 detects this state and outputs a signal. The determination unit 21 receives this signal and recognizes that the bobbin 60 exists within the field of view.

このように、ボビン挿入処理の前後で、ボビン６０が視野内に存在していない状態から、ボビン６０が視野内に存在している状態へと遷移した場合に、判定部２１は、ドッフィング処理が正常に終了した（すなわち不正ドッフィングは発生していない）と判定する。より具体的には、糸切れセンサ１２の信号が、ボビン６０（またはその一部）の存在を示さない状態から、ボビン６０（またはその一部）の存在を示す状態へと変動した場合に、判定部２１は、ドッフィング処理が正常に終了した（すなわち不正ドッフィングは発生していない）と判定する。そうでない場合には、判定部２１は、ドッフィング処理が正常に終了しなかった（すなわち不正ドッフィングが発生した）と判定する。 In this way, before and after the bobbin insertion process, when the state in which the bobbin 60 does not exist in the field of view changes to the state in which the bobbin 60 exists in the field of view, the determination unit 21 determines that the doffing process is performed. It is determined that the processing ended normally (that is, illegal doffing did not occur). More specifically, when the signal from the thread breakage sensor 12 changes from a state in which the bobbin 60 (or a portion thereof) does not exist to a state in which the bobbin 60 (or a portion thereof) does exist, The determination unit 21 determines that the doffing process has ended normally (that is, no illegal doffing has occurred). Otherwise, the determination unit 21 determines that the doffing process did not end normally (that is, illegal doffing occurred).

また、情報処理装置２０は、いずれかの錘１１において不正ドッフィングが発生した場合に、不正ドッフィングを検出した糸切れセンサ１２が対応する錘１１を特定し、その錘１１の位置を携帯端末３０に送信する。携帯端末３０はこれを受信するとともに、作業員に対して出力する。各錘１１の位置を表す情報の形式は任意に設計可能であるが、たとえば、リング精紡機識別情報と、錘ライン識別情報と、錘識別情報との組とすることができる。ここで、リング精紡機識別情報とは、リング精紡機１０を特定する情報であり、たとえば図１に示す複数のリング精紡機１０のうちいずれにその錘が属するかを表す。錘ライン識別情報とは、リング精紡機１０において錘１１が配置された錘ラインを特定する情報であり、たとえば図２に示す２列の錘ラインのうちいずれにその錘が属するかを表す。錘識別情報とは、錘ラインにおいて錘１１が配置された位置を特定する情報であり、たとえばリング精紡機１０の長手方向における錘１１の位置または番号である。 Further, when illegal doffing occurs in any of the weights 11, the information processing device 20 identifies the weight 11 corresponding to the yarn breakage sensor 12 that detected the illegal doffing, and transmits the position of the weight 11 to the mobile terminal 30. Send. The portable terminal 30 receives this and outputs it to the worker. The format of the information representing the position of each spindle 11 can be arbitrarily designed. For example, it can be a set of ring spinning machine identification information, spindle line identification information, and spindle identification information. Here, the ring spinning machine identification information is information for specifying the ring spinning machine 10, and indicates, for example, to which of the plurality of ring spinning machines 10 shown in FIG. 1 the spindle belongs. The weight line identification information is information for specifying the weight line on which the weight 11 is arranged in the ring spinning frame 10, and indicates, for example, to which of the two rows of weight lines shown in FIG. 2 the weight belongs. The weight identification information is information specifying the position where the weight 11 is arranged on the weight line, and is, for example, the position or number of the weight 11 in the longitudinal direction of the ring spinning machine 10 .

作業員は、携帯端末３０からの出力に応じ、たとえば出力された情報に基づいて不正ドッフィングが発生した錘１１の位置まで移動することができる。 The worker can move to the position of the weight 11 where illegal doffing occurs based on the output from the portable terminal 30, for example, based on the output information.

以上説明するように、本発明の実施の形態１に係る不正ドッフィング検出装置によれば、糸切れセンサ１２の検出結果を利用して不正ドッフィングの位置を出力するので、作業員は不正ドッフィングが発生した場所をより容易に特定できる。 As described above, according to the illegal doffing detection device according to the first embodiment of the present invention, the detection result of the yarn breakage sensor 12 is used to output the position of illegal doffing. You can more easily identify where you did it.

また、既存の糸切れセンサ１２を流用することができるので、不正ドッフィングを検出するためのセンサ等を追加で設ける必要がない。 In addition, since the existing yarn breakage sensor 12 can be used, there is no need to additionally provide a sensor or the like for detecting illegal doffing.

上述の実施の形態１において、以下のような変形を施すことができる。
実施の形態１では糸切れセンサ１２は光学式のセンサを備えるが、糸切れセンサ１２の具体的構成は当業者が適宜設計可能である。たとえば磁気式のセンサを備えてもよく、その場合には、尻金６０ａが存在しているか否かに基づいて不正ドッフィングを判定してもよい。磁気式の糸切れセンサの例は、特開２０１４－１６９５１１号公報に記載される。 The following modifications can be applied to the first embodiment described above.
Although the yarn breakage sensor 12 is provided with an optical sensor in the first embodiment, the specific configuration of the yarn breakage sensor 12 can be appropriately designed by those skilled in the art. For example, a magnetic sensor may be provided, in which case illegal doffing may be determined based on whether or not the end piece 60a is present. An example of a magnetic yarn breakage sensor is described in JP-A-2014-169511.

実施の形態１では、管糸抜き取り失敗判定では管糸７０の存在を基準としているが、ボビン６０または他の構成要素の存在を基準としてもよいし、他の判定方法または判定基準を用いてもよい。また、ボビン挿入失敗判定ではボビン６０の存在を基準としているが、他の構成要素の存在を基準としてもよいし、他の判定方法または判定基準を用いてもよい。 In the first embodiment, the presence of the cop 70 is used as a criterion for judging the failure to remove the cop, but the presence of the bobbin 60 or other components may be used as a criterion, or other determination methods or criteria may be used. good. Also, although the bobbin insertion failure determination is based on the presence of the bobbin 60, the presence of other components may be used as the standard, and other determination methods or criteria may be used.

「不正ドッフィング」の定義は任意に設計可能である。実施の形態１では、不正ドッフィングの判定は管糸抜き取り失敗判定およびボビン挿入失敗判定の双方を含むが、変形例としていずれか一方を除外してもよい。また、ドッフィングに関連して行われる他の処理について、その処理が失敗した場合に不正ドッフィングが発生したと判定するように構成してもよい。 The definition of "illegal doffing" can be designed arbitrarily. In the first embodiment, the determination of illegal doffing includes both the unsuccessful determination of unspooling of the bobbin thread and the unsuccessful determination of bobbin insertion, but as a modification, either one may be excluded. Further, it may be configured such that it is determined that illegal doffing has occurred when other processing performed in relation to doffing fails.

糸切れセンサ１２が糸切れを検知した場合に、出力部（実施の形態１では携帯端末３０）が糸切れ錘の位置を表す情報を出力するように構成してもよい。この場合には、携帯端末３０は、ドッフィング期間内には不正ドッフィング錘の位置を出力し、非ドッフィング期間内には糸切れ錘の位置を出力することになる。このようにすると、既存の糸切れセンサ１２のみならず、糸切れ錘の位置を出力するための既存の構成（携帯端末３０が既設である場合等）までも流用することができる。 When the yarn breakage sensor 12 detects the yarn breakage, the output unit (mobile terminal 30 in the first embodiment) may be configured to output information representing the position of the yarn breakage weight. In this case, the portable terminal 30 outputs the position of the incorrect doffing weight during the doffing period, and outputs the position of the broken thread weight during the non-doffing period. In this way, not only the existing yarn breakage sensor 12 but also the existing configuration for outputting the position of the yarn breakage weight (such as when the mobile terminal 30 is already installed) can be used.

不正ドッフィングが発生した錘１１の位置を出力する出力部の具体的構成は、携帯端末３０に限らない。たとえばその錘１１に対応する糸切れ表示ランプ１３を点灯させることによって位置を示してもよい。または、リング精紡機１０に関連して設けられる出力装置であってもよい。より具体的には、所定間隔で配置されるディスプレイ装置（またはこれを備えるコンピュータ）を用いてもよい。 The specific configuration of the output unit that outputs the position of the weight 11 where illegal doffing has occurred is not limited to the mobile terminal 30 . For example, the position may be indicated by lighting the thread break indicator lamp 13 corresponding to the weight 11 . Alternatively, it may be an output device provided in association with the ring spinning machine 10 . More specifically, display devices (or computers equipped with the same) arranged at predetermined intervals may be used.

また、不正ドッフィング検出装置が、作業員の位置を検出するための構成を備えている場合には、作業員をその位置から不正ドッフィングが発生した位置まで誘導してもよい。たとえば特許文献１の段落［００２６］等に記載されるように、作業員の位置から不正ドッフィングの位置に向かう順に糸切れ表示ランプ１３をフラッシュ点灯させてもよい。または、たとえば作業員の位置から不正ドッフィングが発生した位置までの経路を特定し、その経路を表す情報を出力部から出力させてもよい。 Also, if the illegal doffing detection device has a configuration for detecting the position of the worker, the worker may be guided from that position to the position where the illegal doffing occurred. For example, as described in paragraph [0026] of Patent Document 1, the yarn break indicator lamps 13 may be flashed in order from the worker's position to the illegal doffing position. Alternatively, for example, a route from the position of the worker to the position where the illegal doffing occurred may be specified, and information representing the route may be output from the output unit.

また、たとえば情報処理装置２０および携帯端末３０を単一のコンピュータを用いて構成してもよい。このような構成の具体例としては、携帯端末に判定部２１を構成しておき、リング精紡機１０に無線送信機を設けて各糸切れセンサ１２の検出状態を送信させ、携帯端末がこれを受信して不正ドッフィングの有無を判定するようにしてもよい。 Further, for example, information processing device 20 and portable terminal 30 may be configured using a single computer. As a specific example of such a configuration, the determination unit 21 is configured in the mobile terminal, the ring spinning machine 10 is provided with a wireless transmitter to transmit the detection state of each yarn breakage sensor 12, and the mobile terminal transmits this. The presence or absence of illegal doffing may be determined by receiving the information.

実施の形態１では、不正ドッフィングが発生した錘の位置の出力は視覚的方法（画面表示）によって行われるが、出力の方法はこれに限らない。たとえば聴覚的方法（音声等）によって情報を出力してもよい。実施の形態１では、携帯端末３０が音声を出力してもよいし、携帯端末３０を省略して他の装置（作業通路、リング精紡機１０、または情報処理装置２０等に関連して設けられるスピーカー等）が音声を出力するよう構成してもよい。 In Embodiment 1, the position of the weight where illegal doffing has occurred is output by a visual method (screen display), but the output method is not limited to this. For example, the information may be output by an auditory method (such as voice). In Embodiment 1, the mobile terminal 30 may output the voice, or the mobile terminal 30 may be omitted and provided in association with other devices (work passage, ring spinning machine 10, information processing device 20, etc.). A speaker, etc.) may be configured to output sound.

実施の形態１では携帯端末３０は単一のものを用いるが、複数の携帯端末３０を用いてもよい。たとえば作業員ごとに異なる携帯端末３０を用いてもよく、その場合には情報処理装置２０が情報を送信すべき携帯端末３０を特定する方法は任意に設計可能である。たとえば作業員が作業開始前に自身の携帯端末の端末識別情報を情報処理装置２０に入力し、この端末識別情報に基づいて情報処理装置２０が情報を送信してもよい。 Although a single portable terminal 30 is used in Embodiment 1, a plurality of portable terminals 30 may be used. For example, a different mobile terminal 30 may be used for each worker, and in that case, the method of specifying the mobile terminal 30 to which the information processing apparatus 20 should transmit information can be arbitrarily designed. For example, a worker may input terminal identification information of his/her mobile terminal to the information processing device 20 before starting work, and the information processing device 20 may transmit information based on this terminal identification information.
