Abstract
Description
Die Erfindung betrifft ein Verfahren zum Überwachen einer Changierbewegung gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a method for monitoring a traversing movement according to the preamble of claim 1.
Kreuzspulen herstellende Textilmaschinen, beispielsweise Kreuzspulautomaten, sind seit langem bekannt und in der Textilindustrie in großer Stückzahl im Einsatz. Derartige Textilmaschinen verfügen jeweils über eine Vielzahl von gleichartigen Spulstellen, die in Längserstreckung der Textilmaschine nebeneinander angeordnet sind. Die einzelnen Spulstellen weisen neben diversen Fadenhandhabungs- bzw. Fadenbehandlungseinrichtungen oft auch Sensoreinrichtungen auf, mit denen während des Umspulprozesses der laufende Faden abgetastet bzw. der ordnungsgemäße Lauf des Fadens überwacht wird. Diese Sensoreinrichtungen sind in der Regel an einen spulstelleneigenen Steuerungsrechner angeschlossen, der über einen Maschinenbus oder dgl. mit einer Zentralsteuereinheit der Textilmaschine in Verbindung steht. Solche Sensoreinrichtungen zum Überwachen des laufenden Fadens bzw. zum Überwachen eines ordnungsgemäßen Laufes des Fadens sind beispielsweise ein elektronischer Fadenreiniger, eine spezielle Changierüberwachungseinrichtung und/oder ein Fadenzugkraftsensor.cheese producing textile machines, for example automatic winder, have long been known and in the textile industry in large numbers in use. Such textile machines each have over a variety of similar winding units, in longitudinal extension the textile machine are arranged side by side. The single ones Winding points have in addition to various thread handling or thread treatment facilities often also sensor devices with which during the Umspulprozesses the current thread scanned or the proper Run of the thread is monitored. These sensor devices are usually to a Spulstellene own control computer connected via a machine bus or the like with a central control unit of the textile machine is in communication. Such sensor devices for monitoring the current Thread or to monitor a proper Run of the thread, for example, an electronic thread cleaner, a special trawler monitoring device and / or a yarn tension sensor.

Die bekannten Changierüberwachungseinrichtungen stellen insgesamt verhältnismäßig kostenintensive Einrichtungen dar, da zum Gewinnen einer verwertbaren Messgröße ein relativ hoher messtechnischer Aufwand erforderlich ist. Zur Auswertung der von den Dehnmessstreifen beziehungsweise den triboelektrischen oder den piezoelektrischen Elementen gelieferten analogen Signale sind beispielsweise relativ empfindliche Sensoren erforderlich, deren Ausgangssignale anschließend zur Auswertung verstärkt werden müssen.The known traverse monitoring devices make a total relatively expensive facilities because, to gain a usable measurand a relatively high metrological effort is required. to Evaluation of the strain gauges or the triboelectric or analog signals supplied to the piezoelectric elements For example, relatively sensitive sensors are required whose output signals are then amplified for evaluation Need to become.

Die Ausgangssignale des Fadensensors, der den in die Spinnzentrifuge einlaufenden Faden abtastet, werden jeweils über einen Filter geführt, der aus dem anliegenden Rauschsignal Signalanteile in einem bestimmten Frequenzband herausfiltert, die im Bereich einer am Fadensensor wirksamen Ballonfrequenz liegen. Der herausgefilterte Frequenzbereich wird anschließend über einen Frequenzauswerter geführt und dabei einer Fourier-Transformation unterzogen.The Output signals of the thread sensor, the in the spinning centrifuge incoming thread scans are each over a Filter, which consists of the applied noise signal signal components in a certain frequency band that filters out in the range of lie on the thread sensor effective balloon frequency. The filtered out Frequency range is then via a frequency evaluator guided and subjected to a Fourier transform.
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zum Betreiben einer Spulstelle zu entwickeln, das auf einfache und kostengünstige Weise eine zuverlässige Überwachung einer Fadenchangiereinrichtung einer Spulstelle ermöglicht.outgoing From the aforementioned prior art, the invention is the task to develop a method for operating a winding unit, that in a simple and cost effective way reliable monitoring a Fadenchangiereinrichtung a winding station allows.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren mit den im Anspruch 1 genannten Merkmalen gelöst.These The object is achieved by a method solved with the features mentioned in claim 1.
Vorteilhafte Ausgestaltungen des Verfahrens sind Gegenstand der Unteransprüche.advantageous Embodiments of the method are the subject of the dependent claims.
Das erfindungsgemäße Verfahren weist den Vorteil auf, dass es sich um ein kostengünstig zu realisierendes Verfahren handelt, das ohne den Einsatz zusätzlicher kostspieliger Messeinrichtungen realisiert werden kann. Das heißt, mittels eines an der Spulstelle bereits vorhandenen Fadenzugkraftsensors werden die bei der Traversierung eines Fadens auftretenden Fadenzugkraftänderungen erfasst und in verwertbare Messsignale umgesetzt. Diese Messsignale werden anschließend in einer spulstelleneigenen Steuereinrichtung dahingehend bearbeitet, dass aus dem Spektrum der Messsignale des Fadenzugkraftsensors die Messsignale ausgewertet werden, die eine Aussage über die Arbeitsweise der Fadenchangiereinrichtung enthalten.The inventive method has the advantage that it is a cost-effective to implement method does that without the use of additional costly Measuring devices can be realized. That is, by means of an already present at the winding station yarn tension sensor become the thread tension changes that occur during the traversing of a thread recorded and converted into usable measurement signals. These measurement signals are then in a Spulstelleneigenen control device edited so that from the spectrum of the measuring signals of Fadenzugkraftsensoren the measurement signals are evaluated, the one Statement about the operation of the Fadenchangiereinrichtung contain.
Wie in den Ansprüchen 2 und 3 beschrieben, ist vorzugsweise vorgesehen, dass das Spektrum der Messsignale des Fadenzugkraftsensors in der spulstelleneigenen Steuereinrichtung einer Frequenzanalyse, insbesondere einer Fourier-Transformation, unterzogen wird. Durch eine solche Fourier-Transformation können auf relativ einfache Weise aus den Messsignalen hochfrequente Anteile, die zum Beispiel durch die Changierung des Fadens verursacht werden, herausgefiltert werden.As in claims 2 and 3 is preferred provided that the spectrum of the measured signals of the yarn tension sensor in the bobbin-own controller of a frequency analysis, in particular a Fourier transformation. By Such a Fourier transform can be relatively simple Way from the measurement signals high-frequency components, for example caused by the traversing of the thread, filtered out become.
Da die Geschwindigkeit der Fadenverlegung während des Umspulprozesses und damit die Frequenz der durch die Fadenchangierung verursachten Fadenzugkraftänderungen bekannt ist, ist es außerdem vorteilhaft, wenn das Spektrum der Messsignale des Fadenzugkraftsensors auf die bekannte Frequenz der changierbedingten Fadenzugkraftänderungen hin überwacht wird.There the speed of thread laying during the rewinding process and thus the frequency of the thread tension changes caused by the threading is known, it is also advantageous if the spectrum the measured signals of the yarn tension sensor to the known frequency monitors the change-induced yarn tension changes becomes.
Beim Fehlen von Messsignalen mit dieser bekannten Frequenz kann auf einen Fehler in der Fadenchangierung geschlossen werden.At the Absence of measurement signals with this known frequency can be at one Errors in the thread crossing are closed.
Die Erfindung wird nachfolgend anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert.The Invention is described below with reference to an illustrated in the drawings Embodiment explained in more detail.
