Definitions
- the present invention relates to a device for monitoring a warp thread, in particular a leno warp thread according to the preamble of claim 1.
- the invention further relates to weaving machines with a device according to the invention.
- one or more leno edges can be created with warp threads by means of a leno weave to create a solidified fabric edge.
- These warp threads also called leno warp threads, are usually guided and monitored separately from the other warp threads. It is known to monitor breakage of a warp thread with a warp thread monitor by detecting whether a warp thread is present or not.
- the object of the present invention is to develop a device for monitoring a warp thread, in particular a leno warp thread, in such a way that it has improved properties with regard to the monitoring of the warp thread.
- the advantages of the invention can be seen in the fact that the withdrawal movement or the withdrawal speed of the warp threads can be detected approximately or precisely with an electronic sensor, in particular it can be determined whether the withdrawal movement or the withdrawal speed has a very low or a relatively high value. If the value is very low, especially if the warp threads are at a standstill during the weaving process, it can be concluded that the warp thread has broken. If the take-up speed value is above a predefinable threshold value, it can be concluded that the warp thread has been torn away in an undesirable manner, so that an error signal is generated in order to interrupt the weaving process.
- the electronic signals from the sensors are fed to a signal processing device, the one can include digital or analog evaluation electronics, for example also a microprocessor, in order to compare a measured value with a predeterminable target value and, when it is exceeded or undershot, to generate an error signal which is forwarded to a higher-level unit, for example to shut down a weaving machine.
- digital or analog evaluation electronics for example also a microprocessor
- the rotor 1 shows the device according to the invention in combination with a row shed weaving machine with a weaving rotor 1 rotating in the direction of rotation 1a.
- the rotor 1 has guide elements 2a, 2b, 2c, into which the warp threads 3a, 3b are inserted by means of an insertion device 9a, 9b, that the guide elements 2a, 2b, 2c form an open shed into which the weft threads 10a, 10b can be inserted.
- the insertion device 9a, 9b controls the insertion of the warp threads 3a, 3b in such a way that an edge 3d forms at the edge of the fabric 11, which comprises weft threads 10c, 10d.
- an arrangement 5 for detecting the movement of the warp threads 3a, 3b comprises for each warp thread 3a, 3b a thread roll 5a, 5b, on which the warp thread 3a, 3b rests, and through the warp thread 3a moving in the direction of the fabric 11 , 3b experiences a rotation in the direction of rotation 5f.
- the two Thread rolls 5a, 5b are mounted on a common axis 5e via a coupling part, for example a one-way clutch or a slip clutch 5c, 5d.
- the axis 5e is connected to an electronic sensor 6, which detects the rotation of the axis 5e and forwards the electronic signal via a signal line 7a to a signal processing device 7.
- Eyelets 8 serve to guide the warp threads 3a, 3b in order to guide them on the thread roll 5a, 5b and to ensure an approximately constant wrap angle.
- the thread rolls 5a, 5b can, as shown, be wrapped around only with a fraction of a full circle, or can be wrapped around several times in order to thereby increase the friction between warp thread 3a, 3b and thread roll 5a, 5b.
- the device according to FIG. 1 has the advantage that a plurality of warp threads can be monitored simultaneously with a single sensor. Not shown in FIG. 1 are braking devices which may be necessary in order to bring about a braking force on the warp threads 3a, 3b, for example between the thread supply 4a, 4b and the thread roll 5a, 5b.
- the angular velocity of the weaving rotor 1 in the direction of rotation 1a is significantly higher during weaving than the speed of the movement of the warp thread 3a, 3b in the direction of the fabric 11. If a warp thread 3a, 3b is inserted into a guide element 2a, 2b, 2c, an error occurs, such as this is shown for example on the basis of the warp thread 3c, the warp thread 3c may be entrained by the guide element 2b and thereby accelerated to a speed which is determined by the angular speed of the weaving rotor 1. If such an acceleration occurs in one or both of the twist threads 3a, 3b, the rotational speed of the common axis 5e accelerates, so that the occurrence of such an error can be detected by the sensor 6.
- the signal processing device 7 is a threshold value 12 can be specified, at which the signal processing device 7 exceeds or falls below an error signal 13, for example to stop the weaving rotor 1.
- the arrangement 5 also allows a thread break to be detected. If, during weaving, the angular velocity falls below a predefinable target value, for example when a thread reel 5a, 5b is at a standstill, it can be concluded that a thread breakage of the warp thread 3a, 3b has occurred, or that the thread supply 4a, 4b has been used up.
- the arrangement 16 consists of two sensors 6a, 6b, which are spaced apart in the running direction of the warp thread 3a and monitor the warp thread 3a.
- the electronic signals from the sensors 6a, 6b are fed via signal lines 7a, 7b to a signal processing device 7 which determines the speed of the warp thread 3a by means of a correlation of the measured values.
- the part of the warp thread 3a lying between the two sensors 6a, 6b is guided through eyelets 8 on a line which is as straight as possible, a thread brake 14 acting on the warp thread 3a keeping the warp thread 3a stretched.
- the warp thread 3a is deflected via a thread roll 5a and fed to a weaving machine.
- the sensors 6a, 6b are based, for example, on an optical or capacitive measuring principle.
- Another arrangement 16 for determining the speed of the warp thread 3b comprises three eyelets 8, 8a in order to deflect the warp thread 3b in a U-shape, the eyelet 8a designed as holding means being elastic Element, for example a spring 15, is connected to a solid body.
- the eyelet 8a experiences a deflection which can be detected by a sensor 6c, for example an optical sensor or a displacement sensor, and is fed to a signal processing device 7 via a signal line 7c.
- the arrangement 16 also allows a jerky deflection of the warp thread 3b to be detected.
- FIG. 3 shows an example of a leno weave, consisting of three warp threads 3a, 3b, 3c, which can be produced with a row shed weaving machine according to FIG. 1 if three warp threads 3a, 3b, 3c controlled by insertion devices 9a, 9b are used for this purpose.
- the number of warp threads required depends on the type of fabric edge or auxiliary edge to be created.
- the warp threads 3a, 3b, 3c are expressed in more differentiated terms than leno warp threads 3a, 3c and as a standing thread 3b.

Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Überwachen eines Kettfadens, insbesondere eines Dreherkettfadens gemäss dem Oberbegriff von Anspruch 1. Weiter betrifft die Erfindung Webmaschinen mit einer erfindungsgemässen Vorrichtung.The present invention relates to a device for monitoring a warp thread, in particular a leno warp thread according to the preamble of
An den Rändern eines Gewebes können mit Kettfäden durch eine Dreherbindung eine oder mehrere Dreherkanten erzeugt werden, um eine verfestigte Gewebekante zu erstellen. Diese Kettfäden, auch Dreherkettfäden genannt, werden üblicherweise getrennt von den übrigen Kettfäden geführt und überwacht. Es ist bekannt mit einem Kettfadenwächter einen Bruch eines Kettfadens zu überwachen, indem detektiert wird, ob ein Kettfaden vorhanden ist oder nicht.At the edges of a fabric, one or more leno edges can be created with warp threads by means of a leno weave to create a solidified fabric edge. These warp threads, also called leno warp threads, are usually guided and monitored separately from the other warp threads. It is known to monitor breakage of a warp thread with a warp thread monitor by detecting whether a warp thread is present or not.
Bei gewissen Webverfahren oder Webmaschinen, so zum Beispiel bei Mehrphasenwebmaschinen mit einem Webrotor, ergibt sich das Problem, dass ein Kettfaden beziehungsweise ein Dreherkettfaden vom sich drehende Webrotor erfasst und auf den Webrotor aufgewickelt werden kann, ohne dass der Kettfaden oder Dreherkettfaden dabei reisst. Die bekannten Kettfadenwächter können einen solchen Fehler nicht erkennen.With certain weaving processes or weaving machines, for example with multi-phase weaving machines with a weaving rotor, the problem arises that a warp thread or leno warp thread can be gripped by the rotating weaving rotor and wound onto the weaving rotor without the warp thread or leno warp thread breaking. The known warp thread monitors cannot detect such an error.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Überwachen eines Kettfadens, insbesondere eines Dreherkettfadens, derart weiterzubilden, dass sie bezüglich der Überwachung des Kettfadens verbesserte Eigenschaften aufweist.The object of the present invention is to develop a device for monitoring a warp thread, in particular a leno warp thread, in such a way that it has improved properties with regard to the monitoring of the warp thread.
Diese Aufgabe wird erfindungsgemäss gelöst durch den Gegenstand mit den in Anspruch 1 definierten Merkmalen. Die Unteransprüche 2 bis 9 beziehen sich auf weitere, vorteilhafte Ausgestaltungen der Erfindung. Weiter bezieht sich die Erfindung auf Webmaschinen mit einer erfindungsgemässen Vorrichtung.This object is achieved according to the invention by the object with the features defined in
Die Vorteile der Erfindung sind darin zu sehen, dass die Abzugsbewegung oder die Abzugsgeschwindigkeit der Kettfäden mit einem elektronischen Sensor ungefähr oder genau erfassbar ist, insbesondere ist feststellbar, ob die Abzugsbewegung beziehungsweise die Abzugsgeschwindigkeit einen sehr tiefen oder einen relativ hohen Wert aufweist. Bei einem sehr tiefen Wert, insbesondere bei einem Stillstand der Kettfäden beim laufenden Webvorgang, kann auf einen Bruch des Kettfadens geschlossen werden. Bei einem über einem vorgebbaren Schwellenwert liegenden Wert der Abzugsgeschwindigkeit kann geschlossen werden, dass der Kettfaden auf eine unerwünschte Art fortgerissen wurde, sodass ein Fehlersignal erzeugt wird, um den Webvorgang zu unterbrechen.The advantages of the invention can be seen in the fact that the withdrawal movement or the withdrawal speed of the warp threads can be detected approximately or precisely with an electronic sensor, in particular it can be determined whether the withdrawal movement or the withdrawal speed has a very low or a relatively high value. If the value is very low, especially if the warp threads are at a standstill during the weaving process, it can be concluded that the warp thread has broken. If the take-up speed value is above a predefinable threshold value, it can be concluded that the warp thread has been torn away in an undesirable manner, so that an error signal is generated in order to interrupt the weaving process.
Nebst den in den Ausführungsbeispielen dargestellten Methoden gibt es eine Vielzahl von Möglichkeiten, die Abzugsbewegung oder die ungefähre Geschwindigkeit eines Fadens zu überwachen, so zum Beispiel optische Korrelationsmessungen, kapazitive Messungen, Messungen mit Laser usw.In addition to the methods shown in the exemplary embodiments, there are a multitude of options for monitoring the withdrawal movement or the approximate speed of a thread, for example optical correlation measurements, capacitive measurements, measurements with laser, etc.
Die elektronischen Signale der Sensoren werden einer Signalverarbeitungsvorrichtung zugeführt, die eine digitale oder analoge Auswerteelektronik umfassen kann, so z.B. auch einen Mikroprozessor, um einen gemessenen Wert mit einem vorgebbaren Sollwert zu vergleichen, und bei dessen Über- oder Unterschreiten ein Fehlersignal zu erzeugen, das einer übergeordneten Einheit weitergeleitet wird, um zum Beispiel eine Webmaschine stillzusetzen.The electronic signals from the sensors are fed to a signal processing device, the one can include digital or analog evaluation electronics, for example also a microprocessor, in order to compare a measured value with a predeterminable target value and, when it is exceeded or undershot, to generate an error signal which is forwarded to a higher-level unit, for example to shut down a weaving machine.

Fig. 1 zeigt die erfindungsgemässe Vorrichtung in Kombination mit einer Reihenfachwebmaschine mit einem in Drehrichtung 1a drehenden Webrotor 1. Der Rotor 1 weist Führungselemente 2a, 2b, 2c auf, in die mittels einer Einlegevorrichtung 9a, 9b die Kettfäden 3a, 3b derart eingelegt werden, dass durch die Führungselemente 2a, 2b, 2c ein offenes Webfach gebildet wird, in das die Schussfäden 10a, 10b eintragbar sind. Die Einlegevorrichtung 9a, 9b steuert das Einlegen der Kettfäden 3a, 3b derart, dass sich am Rand des Gewebes 11, das Schussfäden 10c, 10d umfasst, eine Kante 3d bildet. Eine Anordnung 5 zum Erfassen der Bewegung der Kettfäden 3a, 3b umfasst im vorliegenden Ausführungsbeispiel für jeden Kettfaden 3a, 3b eine Fadenrolle 5a, 5b, auf welcher der Kettfaden 3a, 3b aufliegt, und die durch den sich in Richtung des Gewebes 11 bewegenden Kettfaden 3a, 3b eine Rotation in Drehrichtung 5f erfährt. Die beiden Fadenrollen 5a, 5b sind über ein Kupplungsteil, z.B. eine Freilaufkupplung oder eine Rutschkupplung 5c, 5d, auf einer gemeinsamen Achse 5e gelagert. Die Achse 5e ist mit einem elektronischen Sensor 6 verbunden, der die Drehung der Achse 5e erfasst, und das elektronische Signal über eine Signalleitung 7a einer Signalverarbeitungsvorrichtung 7 weiterleitet. Ösen 8 dienen zur Führung der Kettfäden 3a, 3b, um diese auf der Fadenrolle 5a, 5b zu führen und um einen ungefähr konstanten Umschlingungswinkel zu gewährleisten. Die Fadenrollen 5a, 5b können wie dargestellt nur mit einem Bruchteil eines Vollkreises umschlungen sein, oder auch mehrfach umschlungen sein, um dadurch die Reibung zwischen Kettfaden 3a, 3b und Fadenrolle 5a, 5b zu erhöhen. Die Vorrichtung gemäss Fig. 1 weist den Vorteil auf, dass sich mit einem einzigen Sensor eine Mehrzahl von Kettfäden gleichzeitig überwachen lassen. Nicht dargestellt sind in Fig. 1 Bremsvorrichtungen, die unter Umständen erforderlich sind, um auf die Kettfäden 3a, 3b, zum Beispiel zwischen dem Fadenvorrat 4a, 4b und der Fadenrolle 5a, 5b angeordnet ist, eine Bremskraft zu bewirkten.1 shows the device according to the invention in combination with a row shed weaving machine with a
Die Winkelgeschwindigkeit des Webrotors 1 in Drehrichtung 1a ist während dem Webbetrieb wesentlich höher als die Geschwindigkeit der Bewegung des Kettfadens 3a, 3b in Richtung Gewebe 11. Tritt beim Einlegen eines Kettfadens 3a, 3b in ein Führungselement 2a, 2b, 2c ein Fehler auf, wie dies zum Beispiel an Hand des Kettfadens 3c dargestellt ist, so kann es vorkommen, dass der Kettfaden 3c vom Führungselement 2b mitgerissen wird und dadurch auf eine Geschwindigkeit beschleunigt wird, die durch die Winkelgeschwindigkeit des Webrotors 1 bestimmt ist. Tritt eine solche Beschleunigung bei einem oder beiden der Drehfäden 3a, 3b auf, so beschleunigt sich die Rotationsgeschwindigkeit der gemeinsamen Achse 5e, sodass das Auftreten eines solchen Fehlers mit dem Sensor 6 erfassbar ist. Der Signalverarbeitungsvorrichtung 7 ist ein Schwellenwert 12 vorgebbar, bei dessen über- oder unterschreiten die Signalverarbeitungsvorrichtung 7 ein Fehlersignal 13 erzeugt, um zum Beispiel den Webrotor 1 anzuhalten.The angular velocity of the
Ist für jede Fadenrolle 5a, 5b ein separater Sensor 6 zur Erfassung der Rotation vorgesehen, so erlaubt die Anordnung 5 auch einen Fadenbruch zu detektieren. Unterschreitet beim Weben die Winkelgeschwindigkeit einen vorgebbaren Sollwert, zum Beispiel bei einem Stillstand einer Fadenrolle 5a, 5b, so kann daraus geschlossen werden, dass ein Fadenbruch des Kettfadens 3a, 3b aufgetreten ist, oder dass der Fadenvorrat 4a, 4b aufgebraucht ist.If a separate sensor 6 for detecting the rotation is provided for each
Fig. 2 zeigt weitere Ausführungsbeispiele von Vorrichtungen zum Bestimmen der Geschwindigkeit eines Kettfadens. Die Anordnung 16 besteht aus zwei Sensoren 6a, 6b, die in Laufrichtung des Kettfadens 3a beabstandet sind und den Kettfaden 3a überwachen. Die elektronischen Signale der Sensoren 6a, 6b werden über Signalleitungen 7a, 7b einer Signalverarbeitungsvorrichtung 7 zugeführt, die mittels einer Korrelation der gemessenen Werte die Geschwindigkeit des Kettfadens 3a ermittelt. Das zwischen den beiden Sensoren 6a, 6b liegende Teil des Kettfadens 3a wird durch Ösen 8 auf einer möglichst geraden Linie geführt, wobei eine auf den Kettfaden 3a wirkende Fadenbremse 14 den Kettfaden 3a gestreckt hält. Der Kettfaden 3a wird über eine Fadenrolle 5a umgelenkt und einer Webmaschine zugeführt. Die Sensoren 6a, 6b basieren zum Beispiel auf einem optischen oder kapazitiven Messprinzip.2 shows further exemplary embodiments of devices for determining the speed of a warp thread. The
Eine weitere Anordnung 16 zum Bestimmen der Geschwindigkeit des Kettfadens 3b umfasst drei Ösen 8, 8a, um den Kettfaden 3b U-förmig auszulenken, wobei die als Haltemittel ausgebildete Öse 8a über ein elastisches Element, zum Beispiel einer Feder 15, mit einem festen Körper verbunden ist. Die Öse 8a erfährt, abhängig von der Geschwindigkeit des Kettfadens 3b, eine Auslenkung, die mit einem Sensor 6c, zum Beispiel einem optischen Sensor oder einem Wegsensor, erfassbar ist, und über eine Signalleitung 7c einer Signalverarbietungsvorrichtung 7 zugeführt wird. Die Anordnung 16 erlaubt auch eine ruckartige Auslenkung des Kettfadens 3b zu detektieren.Another
Fig. 3 zeigt ein Beispiel einer Dreherbindung, bestehend aus drei Kettfäden 3a, 3b, 3c, die mit einer Reihenfachwebmaschine gemäss Fig. 1 erstellbar ist, wenn dazu drei durch Einlegevorrichtungen 9a, 9b angesteuerte Kettfäden 3a, 3b, 3c verwendet werden. Die Anzahl der erforderlichen Kettfäden hängt ab von der Art einer zu erstellenden Gewebekante beziehungsweise einer Hilfskante. In der vorliegenden Dreherbindung werden die Kettfäden 3a, 3b, 3c differenzierter ausgedrückt als Dreherkettfäden 3a, 3c und als ein Steherfaden 3b bezeichnet.FIG. 3 shows an example of a leno weave, consisting of three
