Description

本発明は、請求項１の上位概念に記載の形式の、綾巻きパッケージを製造する繊維機械の作業部位を運転する方法に関する。   The present invention relates to a method for operating a work site of a textile machine for manufacturing a trawl package, of the type described in the superordinate concept of claim 1.

綾巻きパッケージを製造する繊維機械、たとえば自動ワインダは、長年来公知である。このような自動ワインダは、通常列を成して相並んで配置された同形の多数の作業部位を備えており、作業部位は、様々な糸処理装置もしくは糸監視装置を備えている。このような糸処理装置もしくは糸監視装置の制御および監視は、作業部位計算機を介して行われ、個々の作業部位計算機は、多くの場合機械バスを介して、自動ワインダの中央制御ユニットに接続されている。   Textile machines, such as automatic winders, that produce twill packages have been known for many years. Such an automatic winder is provided with a large number of work parts having the same shape, which are arranged side by side in a normal row, and the work parts are provided with various yarn processing devices or yarn monitoring devices. Control and monitoring of such a yarn processing device or yarn monitoring device is performed via a work site computer, and each work site computer is often connected to a central control unit of an automatic winder via a machine bus. ing.

自動ワインダの作業部位におけるヤーン材料の供給および取出は、たとえばパッケージおよびボビン搬送システムを介して行われる。パッケージおよびボビン搬送システムでは、搬送皿上で直立して、通常紡績コップまたは空管である供給ボビンが循環する。   The supply and removal of the yarn material at the work site of the automatic winder takes place, for example, via a package and bobbin transport system. In the package and bobbin transport system, a supply bobbin, usually a spinning cup or an empty tube, circulates upright on a transport tray.

パッケージおよびボビン搬送システムの代わりに、繊維機械は、作業部位独自の紡績コップマガジンを備えることもできる。そのような作業部位独自の紡績コップマガジンは、有利にはいわゆる円形マガジン（Rundmagazine）として形成されており、これは作業員によって手動で装着される。   As an alternative to the package and bobbin transport system, the textile machine can also have its own spinning cup magazine. Such a unique spinning cup magazine is preferably formed as a so-called circular magazine, which is manually mounted by the operator.

さらにそのような自動ワインダは、作業部位に自動的に供給を行う供給装置を備えている。そのような供給装置、たとえばいわゆる綾巻きパッケージ交換器は、完成した綾巻きパッケージを作業部位のパッケージフレームから取り出して、綾巻きパッケージを機械長さの搬送装置に搬送し、搬送装置は、綾巻きパッケージを機械端部側に配置された引渡ステーションに搬送し、新たな空管を該当する作業部位のパッケージフレームに入れ換える。   Further, such an automatic winder includes a supply device that automatically supplies the work site. Such a supply device, for example, a so-called traverse package changer, takes a completed traverse package from the package frame at the work site and transports the traverse package to a machine-length transport device. The package is transported to a delivery station arranged on the machine end side, and a new empty tube is replaced with the package frame of the corresponding work site.

ヤーンを容積の小さな紡績コップから多量のヤーンを有する綾巻きパッケージに巻き返す間、糸は、糸エラーに関して検査され、この場合検出されたエラーは解消される。走行する糸は、巻き返しに際してさらに糸張力センサによって監視され、糸張力は、糸テンショナによって所定のレベルで維持される。つまり糸テンショナによって、走行する糸のほぼ一定の糸張力が調節され、このようにして綾巻きパッケージに対する糸の均等な巻取が保証される。   While the yarn is rewound from a small volume spinning cup into a traverse package having a large amount of yarn, the yarn is inspected for yarn errors, in which case the detected error is eliminated. The traveling yarn is further monitored by a yarn tension sensor during rewinding, and the yarn tension is maintained at a predetermined level by a yarn tensioner. In other words, the yarn tensioner adjusts the substantially constant yarn tension of the running yarn, thus ensuring even winding of the yarn around the traverse package.

走行する糸の現行の糸張力を検出する糸張力センサは、たとえばドイツ連邦共和国特許出願公開第４１２９８０３号明細書から公知である。この場合糸張力センサは、走行する糸の糸張力測定を実施し、糸テンショナの調節信号を形成し、糸テンショナは、調節信号に応じて、多少の大きさの制動作用を走行する糸に及ぼす。このためにたとえばドイツ連邦共和国特許出願公開第４１３０３０１号明細書に記載されたそのような糸テンショナは、可変の押圧力で負荷可能な糸制動装置を備えている。糸テンショナと糸張力センサとの協働によって、ヤーンが規定の糸張力で巻取ボビンに巻き取られるよう保証される。つまり糸張力センサが糸張力の増大を送信すると、糸テンショナは、幾分か開かれて、糸張力の増加を補償する。   A yarn tension sensor for detecting the current yarn tension of a running yarn is known, for example, from DE 41 29 803 A1. In this case, the yarn tension sensor measures the yarn tension of the traveling yarn and forms an adjustment signal for the yarn tensioner. The yarn tensioner exerts a slight braking action on the traveling yarn according to the adjustment signal. . For this purpose, such a thread tensioner described, for example, in German Offenlegungsschrift 4 130 301 is provided with a thread braking device which can be loaded with a variable pressing force. The cooperation of the thread tensioner and the thread tension sensor ensures that the yarn is wound on the winding bobbin with a defined thread tension. That is, when the yarn tension sensor sends an increase in yarn tension, the yarn tensioner is opened somewhat to compensate for the increase in yarn tension.

これに応じて糸張力センサが糸張力の低下を送信すると、糸テンショナは幾分か閉じられる。   In response, when the thread tension sensor transmits a decrease in thread tension, the thread tensioner is somewhat closed.

もちろん自動ワインダの運転に際して、問題となる運転状況の生じる恐れがあり、この場合糸張力センサと糸テンショナとの前述の協働は、もはや完全には機能しない。   Of course, when operating an automatic winder, a problematic operating situation may occur, in which case the aforementioned cooperation between the yarn tension sensor and the yarn tensioner no longer works perfectly.

たとえばドイツ連邦共和国特許出願公開第１９８４８８８１号明細書に記載されているように、糸エラーの解消に関して、特に撚り継ぎ過程のあとで紡績コップに糸絡まりが生じる場合、糸テンショナが開いているにもかかわらず、糸の糸張力は大幅に高まる。ドイツ連邦共和国特許出願公開第１９８４８８８１号明細書によれば、そのような糸絡まりは次のように検出して解消され、つまり下糸と上糸とを結合したあとで、生じる糸張力を糸張力センサによって検出して、検出値を作業部位計算機で処理し、制限値を超える場合に糸絡まりが推測され、該当する作業部位のパッケージ交換器が作動させられ、パッケージ交換が行われる。   For example, as described in German Patent Application No. 19848881, the yarn tensioner is open when it is necessary to eliminate the yarn error, particularly when the spinning cup is entangled after the splicing process. Regardless, the yarn tension is significantly increased. According to German Patent Application No. 19848881, such yarn entanglement is detected and resolved as follows, that is, after joining the lower thread and the upper thread, the resulting thread tension is determined as the thread tension. The detected value is detected by the sensor, and the detected value is processed by the work site calculator. When the limit value is exceeded, a thread entanglement is estimated, the package exchanger of the corresponding work site is activated, and the package is replaced.

別の問題となる運転状況は、たとえば糸が糸テンショナの領域で制動皿の間を走行しない、つまり糸が制動皿の前後を通過する場合に生じる。これによって巻き返し過程が直接関与しないので、糸ガイドのエラーは常時直ぐ検出可能とはならない。糸張力の調整エラーによって、エラーを含んだ、通常過度にソフトに巻き取られた巻取パッケージが生じる。   Another problematic operating situation occurs, for example, when the yarn does not travel between the brake discs in the region of the yarn tensioner, i.e. the yarn passes past and behind the brake disc. As a result, the winding process is not directly involved, so yarn guide errors are not always immediately detectable. An error in adjusting the yarn tension results in a take-up package that is usually overly soft and contains errors.

この運転状況を回避するために、ドイツ連邦共和国特許出願公開第１９９０５８６０号明細書では、１方法が記載されており、その方法では、作業部位計算機が、糸張力センサによって検出された糸張力に応じて、糸テンショナの押圧力を設定し、設定された押圧力は、押圧力の所定の限界値と比較され、所定の期間で限界値に到達するか、またはこれを超えると、巻取プロセスは中断される。   In order to avoid this operating situation, German Patent Application No. 1905860 describes one method in which the work site calculator responds to the yarn tension detected by the yarn tension sensor. Set the pressing force of the thread tensioner, the set pressing force is compared with a predetermined limit value of the pressing force, and when the limit value is reached or exceeded in a predetermined period, the winding process is Interrupted.

公知の、極めて小さな糸張力で巻き取られる染色パッケージを製造する際に、糸テンショナが既に完全に開いて、糸張力が所望の値を超えて存在するようになる。そのような場合作業部位計算機によって、該当する作業部位で、システムは比較的低速で作業するので、巻取速度ひいては糸張力は低下させられるが、糸張力が常に所望の値に調節される点に関して、常に、また満足できる程度に常に十分な速さで保証されるものではない。そのような問題となる運転状況の結果として、通常綾巻きパッケージの品質が低下し、この場合綾巻きパッケージの品質低下は多くの場合直ぐには検出されない。   In producing a known dyeing package which is wound up with very low yarn tension, the yarn tensioner is already fully open and the yarn tension is present above the desired value. In such a case, the work site calculator will work at the corresponding work site at a relatively low speed, so that the winding speed and thus the yarn tension is reduced, but the yarn tension is always adjusted to the desired value. It is not always guaranteed fast enough to be satisfactory. As a result of such problematic operating conditions, the quality of the traverse package is usually reduced, and in this case the quality degradation of the traverse package is often not detected immediately.

前述の構成の作業部位および作業部位を運転する方法から出発して、本発明の課題は、綾巻きパッケージを製造する繊維機械の作業部位を運転する方法を改良して、綾巻きパッケージ、特に染色パッケージの高い巻取品質を確実に保証することのできるものを提供することである。   Starting from the working part and the method of operating the working part of the above-mentioned configuration, the object of the present invention is to improve the method of operating the working part of a textile machine for manufacturing a traversing package, and to make a traversing package, in particular dyeing It is to provide a product that can reliably guarantee high winding quality of the package.

この課題は、請求項１の特徴部に記載した構成を有する方法によって解決される。   This problem is solved by a method having the configuration described in the characterizing part of claim 1.

本発明の有利な構成は、従属請求項の対象である。   Advantageous configurations of the invention are the subject matter of the dependent claims.

所望の糸張力値ならびに許容パーセント偏差値が作業部位計算機に入力可能であり、これらの値の維持は、作業部位計算機によってオンラインで監視され、許容されない偏差が生じると、直ちに自動的に巻取プロセスに作用して、アラームを作動させることによって、巻取プロセス全体にわたって限界許容偏差内に糸張力の位置する綾巻きパッケージが製造される。アラーム信号の発生によって、さらに該当する作業部位におけるイレギュラ発生が表示され、作業部位を検査するよう勧告される。   Desired yarn tension values as well as acceptable percent deviation values can be entered into the work site calculator, and the maintenance of these values is monitored online by the work site calculator and automatically and immediately when the unacceptable deviation occurs Acting on and triggering an alarm produces a traverse package in which the yarn tension is located within the critical tolerances throughout the winding process. When an alarm signal is generated, the occurrence of irregularity at the corresponding work site is further displayed, and it is recommended to inspect the work site.

請求項２に記載したように、さらに有利な実施形態では、巻取過程を中断して、アラームを作動させるまえに、糸張力の許容されない過不足の生じ得る期間を、作業部位計算機で調節することができる。つまり作業員は、たとえばヤーン材料または綾巻きパッケージのあとの使用目的に応じて、個別的に、どのような速さで作業部位計算機が、設定された許容限界値の範囲外に位置する確認された糸張力の偏差に反応すればよいか調節することができる。   In a further advantageous embodiment as claimed in claim 2, the work site calculator adjusts the period during which an unacceptable excess or deficiency of thread tension can occur before interrupting the winding process and triggering an alarm. be able to. In other words, the worker can confirm, for example, how fast the work area calculator is outside the set tolerance limits, depending on the intended use after the yarn material or traversing package, for example. It is possible to adjust whether or not it is necessary to react to the deviation of the yarn tension.

請求項３に記載したように、システムの設定可能な反応時間は、０．１〜０．５秒である。実際には、１秒の反応時間が特に有利であることが判明した。   As set forth in claim 3, the settable reaction time of the system is 0.1 to 0.5 seconds. In practice, a reaction time of 1 second has proved to be particularly advantageous.

請求項４に示したように、糸張力が設定された期間に関する許容限界値に到達するか、該許容限界値を超えると、作業部位計算機が制御下の糸切断を行う。そのような糸切断によって、巻取過程は瞬時に中断されて、簡単な形式で、部分的に過度に強くまたは弱く糸層の巻き取られた綾巻きパッケージの生産が回避される。   According to a fourth aspect of the present invention, when the allowable tension value for the set period is reached or exceeds the allowable limit value, the work site calculator performs the controlled yarn cutting. With such yarn cutting, the winding process is interrupted instantaneously, avoiding the production of twill packages in which the yarn layer is wound up in a simple manner, partly too strongly or weakly.

さらに請求項５に記載したように、アラームを作動させ、ひいては作業員に誤った作業を行う作業部位に関して注意を喚起することができる。   Furthermore, as described in claim 5, it is possible to activate an alarm and to alert a worker about a work site where an erroneous work is performed.

以下に図面につき、本発明の実施例を詳しく説明する。   In the following, embodiments of the present invention will be described in detail with reference to the drawings.

図１には、綾巻きパッケージを製造する繊維機械１の作業部位１０を側面図で示した。自動ワインダとして公知のこのような繊維機械は、相並んで配置された多数の作業部位１０を有しており、作業部位１０に供給ボビン１２、有利には紡績コップが大容積の綾巻きパッケージ１４に巻き返される。   FIG. 1 is a side view of a work site 10 of a textile machine 1 that manufactures a twill package. Such a textile machine, known as an automatic winder, has a large number of working parts 10 arranged side by side, and the working parts 10 have a supply bobbin 12, preferably a spun wound package 14 with a large volume of spinning cups 14. Will be rolled back.

この場合紡績コップ１２は、搬送装置１６を介して個々の作業部位１０に到達し、作業部位１０は、それ自体公知のように、詳しくは図示していない多数の搬送区間を有しており、搬送区間に沿って、搬送皿２０上に立てられた紡績コップ１２もしくは空管１８が搬送される。図１に示したように、巻返位置Ｉに配置された紡績コップ１２から糸２２が引き出され、糸２２は、綾巻きパッケージ１４への走行経路上で先ず下糸センサ２８を通過し、下糸センサ２８は、信号線路３０を介して作業部位計算機３２と接続されている。下糸センサ２８によって、たとえば糸切れまたは制御下の糸切断のあとで、上糸検出を導入するまえに、下糸３４が存在するかどうか確認される。下糸センサ２８の上方に糸テンショナ３６が配置されており、糸テンショナ３６は、図２に示したように、２つの制動皿４，５を備えており、制動皿４，５は、走行する糸２２に押圧力を及ぼす。糸テンショナ３６は、制御線路３８を介して同様に作業部位計算機３２と接続されている。   In this case, the spinning cup 12 reaches the individual work sites 10 via the transport device 16, and the work site 10 has a number of transport sections not shown in detail, as is known per se. The spinning cup 12 or the empty tube 18 erected on the conveying tray 20 is conveyed along the conveying section. As shown in FIG. 1, the yarn 22 is pulled out from the spinning cup 12 arranged at the rewind position I, and the yarn 22 first passes through the lower yarn sensor 28 on the traveling path to the traverse package 14, The yarn sensor 28 is connected to the work site calculator 32 via the signal line 30. The lower thread sensor 28 checks whether the lower thread 34 is present, for example after thread breakage or controlled thread cutting, before introducing upper thread detection. A thread tensioner 36 is disposed above the lower thread sensor 28. The thread tensioner 36 includes two braking plates 4, 5 as shown in FIG. 2, and the braking plates 4, 5 travel. A pressing force is applied to the yarn 22. The yarn tensioner 36 is similarly connected to the work site calculator 32 via the control line 38.

糸走行経路上を進むと、ヤーンエラーを確認するために糸クリアラ４４が配置されている。糸クリアラ４４によって、常時走行する糸の品質が監視され、この場合糸クリアラ４４の信号は、評価するために、信号線路４８を介して作業部位計算機３２に送られる。糸エラーが生じると、作業部位計算機３２によって、制御線路５０を介して糸切断装置５２が作動させられて糸２２が分離される。   As the yarn travels along the yarn travel path, a yarn clearer 44 is arranged to confirm a yarn error. The yarn clearer 44 monitors the quality of the constantly running yarn, in which case the yarn clearer 44 signal is sent to the work site calculator 32 via the signal line 48 for evaluation. When a yarn error occurs, the work part calculator 32 operates the yarn cutting device 52 via the control line 50 to separate the yarn 22.

糸走行方向で糸クリアラ４４の下流側に糸張力センサ５４ならびにパラフィン処理装置４６が配置されている。   A yarn tension sensor 54 and a paraffin processing device 46 are disposed downstream of the yarn clearer 44 in the yarn traveling direction.

この場合糸張力センサ５４は、信号線路５６を介して同様に作業部位計算機３２と接続されている。紡績運転（巻返運転）中、糸張力センサ５４によって、常時走行する糸２２の糸張力が監視され、糸張力センサ５４から送られた糸張力信号に応じて、作業部位計算機３２を介して糸テンショナ３６が操作される。要するに糸テンショナ３６の制動皿４，５は、糸２２を押圧力で負荷して、押圧力によって、走行する糸２２にほぼ一定の糸張力が形成されるよう保証され、ほぼ一定の糸張力によって、製造しようとする綾巻きパッケージ１４の均等なパッケージ密度が保証される。   In this case, the yarn tension sensor 54 is similarly connected to the work site calculator 32 via the signal line 56. During the spinning operation (rewinding operation), the yarn tension sensor 54 monitors the yarn tension of the yarn 22 that is constantly running, and the yarn is sent via the work site calculator 32 according to the yarn tension signal sent from the yarn tension sensor 54. The tensioner 36 is operated. In short, the brake plates 4 and 5 of the thread tensioner 36 are loaded with the pressing force of the thread 22 and are guaranteed to form a substantially constant thread tension on the traveling thread 22 by the pressing force, and with a substantially constant thread tension. The uniform package density of the twill package 14 to be manufactured is guaranteed.

パラフィン処理装置４６に続いて糸走行方向でみてさらに糸ガイド５８が設けられており、糸ガイド５８を介して、糸２２は、たとえばいわゆる糸ガイドドラム６０上に走行し、糸ガイドドラム６０は、糸２２を綾巻きで巻き付けるために巻取形式「ランダム巻（パッケージ直径の増加と共に巻取動作が低下し綾角が一定に維持される巻取形式」を提供する。綾巻きパッケージ１４は、図示していない管を介して、旋回可能に支承されたパッケージフレーム６に回動可能に支承されており、この場合外周で、単個モータ式に駆動される糸ガイドドラム６０に接触しており、糸ガイドドラム６０は、摩擦接続を介して綾巻きパッケージ１４を連行する。   A yarn guide 58 is further provided in the yarn traveling direction following the paraffin processing unit 46, and the yarn 22 travels, for example, on a so-called yarn guide drum 60 via the yarn guide 58, and the yarn guide drum 60 is A winding type “random winding (a winding type in which the winding operation decreases as the package diameter increases and the twill angle is maintained constant”) is provided to wind the yarn 22 in a twill winding. It is rotatably supported by a package frame 6 that is pivotally supported via a pipe not shown, and in this case, on the outer periphery, is in contact with a thread guide drum 60 that is driven by a single motor, The yarn guide drum 60 entrains the traverse package 14 via a frictional connection.

レギュラーな糸走行経路の外側に、追加的に糸撚り継ぎ装置４０が配置されており、糸撚り継ぎ装置４０は、信号線路４２を介して同様に作業部位計算機３２と接続されている。   A yarn twisting device 40 is additionally arranged outside the regular yarn traveling path, and the yarn twisting device 40 is similarly connected to the work site calculator 32 via a signal line 42.

作業部位１０は、さらに吸込ノズル７とグリッパ管８とを備えている。グリッパ管８は、紡績コップ１２から到来する下糸を把持するために役立ち、下糸は、糸テンショナの上方で制御下の糸クリアラ切断または糸切れの場合に通常糸テンショナ３６に保持される。   The work site 10 further includes a suction nozzle 7 and a gripper tube 8. The gripper tube 8 serves to grip the lower thread coming from the spinning cup 12, and the lower thread is normally held in the thread tensioner 36 in the event of a controlled thread clearer cut or thread break above the thread tensioner.

吸込ノズル７は、綾巻きパッケージ１４に向かって走行する上糸を収容するのに役立つ。   The suction nozzle 7 serves to accommodate the upper thread that travels toward the traverse package 14.

図２には、作業部位計算機３２、ならびに作業部位計算機３２の、糸テンショナ３６、糸張力センサ５４、糸切断装置５２およびアラーム装置１１との接続回路を概略的に示した。   FIG. 2 schematically shows a work part calculator 32 and a connection circuit of the work part calculator 32 to the thread tensioner 36, the thread tension sensor 54, the thread cutting device 52, and the alarm device 11.

図２に略示した糸テンショナ３６は、それ自体公知で、たとえばドイツ連邦共和国特許出願公開第４１３０３０１号明細書に詳しく記載されている。   The thread tensioner 36 shown schematically in FIG. 2 is known per se and is described in detail, for example, in DE-A-4130301.

糸張力センサ５４として、有利には、たとえば同様にドイツ連邦共和国特許出願公開第４１２９８０３号明細書によって公知の装置が用いられる。電気操作可能な糸切断装置は、たとえば符号５２で示唆したように、繊維機械構造では従来技術として以前から知られている。そのような装置は、通常電磁石によって所望の形式で挿出（伸長）運動可能なカッタを備えており、カッタは、電磁石の通電時にストッパに押し付けられ、この場合カッタの手前で走行する糸は確実に分離される。   As the thread tension sensor 54, it is advantageous to use, for example, a device which is likewise known from German Offenlegungsschrift 4129803. An electrically operable yarn cutting device has been known for some time in the prior art in textile machine construction, for example as suggested by reference numeral 52. Such a device is usually provided with a cutter that can be inserted (extended) in a desired form by an electromagnet, and the cutter is pressed against a stopper when the electromagnet is energized, in which case the yarn traveling in front of the cutter is surely Separated.

本発明による方法の機能：
巻返プロセスの間、紡出パッケージ１２から繰り出される糸２２は、綾巻きパッケージに向かう経路上で、特に糸テンショナ３６の制動皿４、５間を走行する。制動皿４，５の押圧力を規定の形式で調節することによって、糸２２は、少なくともほぼ一定の糸張力で綾巻きパッケージ１４に巻き取られる。糸張力は、巻返プロセス全体の間、オンラインで糸張力センサ５４によって監視される。求められる糸張力実際値ＦＺＫistは、コンパレータ１９内で、糸張力目標値発信器１３によって設定された糸張力目標値ＦＺsollと比較される。出口側でコンパレータ１９は調整装置１７と接続されており、調整装置１７によって、糸テンショナ３６に常時必要な押圧力が加わるようになる。 Function of the method according to the invention:
During the rewinding process, the yarn 22 fed out from the spinning package 12 travels on the path toward the traverse package, particularly between the brake plates 4 and 5 of the yarn tensioner 36. By adjusting the pressing force of the brake dishes 4 and 5 in a prescribed manner, the yarn 22 is wound around the traverse package 14 with at least a substantially constant yarn tension. The yarn tension is monitored online by the yarn tension sensor 54 during the entire rewinding process. The obtained yarn tension actual value FZK ist is compared with the yarn tension target value FZ soll set by the yarn tension target value transmitter 13 in the comparator 19. The comparator 19 is connected to the adjusting device 17 on the outlet side, and the adjusting device 17 applies a necessary pressing force to the yarn tensioner 36 at all times.

適当な調整信号は、糸テンショナ３６の制動皿４，５の特定の押圧力に対応する。求められた糸張力実際値ＦＺＫistは、コンパレータ１９内で、さらに制限値発信器１５によって設定された限界値ＴＧと比較される。 An appropriate adjustment signal corresponds to a specific pressing force of the brake plates 4 and 5 of the thread tensioner 36. The obtained actual yarn tension value FZK ist is further compared with the limit value TG set by the limit value transmitter 15 in the comparator 19.

コンパレータ１９が、比較に際して、糸張力実際値ＦＺＫistが所定の期間ＺＳで限界値ＴＧに到達したこと、またはこれを超過したことを認識すると、調節線路５０を介して、糸切断装置５２が作動させられて、走行する糸２２が分離される。さらに信号線路３１を介してアラーム装置１１が作動させられて、該当する作業部位１０が停止される。 When the comparator 19 recognizes that the actual yarn tension value FZK ist has reached or exceeded the limit value TG in the predetermined period ZS during the comparison, the yarn cutting device 52 is activated via the adjustment line 50. As a result, the traveling yarn 22 is separated. Furthermore, the alarm device 11 is operated via the signal line 31 and the corresponding work site 10 is stopped.
