Abstract

The weft selecting and feeding device contains an electronically controllable electric motor 2 having a driving wheel 4 and a deflecting wheel 5 and a toothed belt 6 which loops round these wheels. Yarn feeders 7, 7a are so fastened offset to one another on the two longitudinal strands of the toothed belt 6 that one yarn feeder 7a is in the position of readiness B and the other in the transfer position U. The yarn feeders 7, 7a possess a yarn eye 9, through which the weft yarns 17, 17a run. In the position of readiness B, the weft yarn 14a is outside the take-up region of the weft-insertion member 15; in the transfer position U, the weft yarn 17 is presented to this. According to the particular pattern and in synchronism with the weaving cycle, the electric motor 2 rotates the driving wheel 4 and thereby moves the toothed belt 6, the positions of the yarn feeders 7, 7a being positively interchanged. …<IMAGE>…

Description

Die Erfindung betrifft eine Schussfadenauswahl- und Zuführvorrichtung für Webmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a weft selection and feeding device for a weaving machine according to the preamble of claim 1.

Bekannte Auswählvorrichtungen wie z.B. BE 8800691 oder CH 1285/87 verwenden durch Steuerkurven bewegte Stoss- und Zugelemente an die mittels Elektromagnete Übertragungsorgane, die an Fadenzubringer gekoppelt sind, an- oder abgekuppelt werden. Die für solche Vorrichtungen notwendige Mechanik beinhaltet neben den Steuerkurven eine Vielzahl von Hebeln, Klinken, Federn, Drehpunkte und Magnete. Diese Vorrichtungen sind dadurch bei den heute erreichbaren hohen Webgeschwindigkeiten anfällig auf Funktionssicherheit und Verschleiß und können unangenehme Lärmquelle sein; zudem ist eine schonende Führung der Schussfäden wegen Vibrationsanfälligkeit gefährdet.Known selection devices such as BE 8800691 or CH 1285/87 use push and pull elements which are moved by control cams and to which transmission elements, which are coupled to thread feeders, are coupled or uncoupled by means of electromagnets. The mechanics required for such devices include, in addition to the control cams, a large number of levers, pawls, springs, pivot points and magnets. These devices are therefore susceptible to functional reliability and wear at the high weaving speeds that can be achieved today and can be an unpleasant source of noise; In addition, careful guiding of the weft threads is at risk due to the susceptibility to vibrations.

Der Erfindung liegt die Aufgabe zugrunde, eine einfache und funktionssichere Auswahl- und Zuführvorrichtung zu schaffen, die leicht zu bedienen und servicefreundlich ist.The invention has for its object to provide a simple and reliable selection and feeding device that is easy to use and easy to service.

Die Vorrichtung besteht aus einem Gehäuse mit angeflanschtem Elektromotor, vorzugsweise ein Schrittmotor oder DC-Motor. Auf der Motorwelle ist ein Antriebsrad drehfest angeordnet. Unterhalb des Antriebsrades ist ein Umlenkrad am Gehäuse befestigt. Ein Riemen, vorzugsweise ein Zahnriemen, oder eine Rollenkette umschlingt die beiden Räder. An den beiden Riementrums ist je ein Fadenzubringer formschlüssig so befestigt, daß ein Fadenzubringer in der Bereitschaftsstellung ist, während der andere in der Übergabestellung ruht. Müssen die Fadenzubringer ihre Endstellungen wechseln, dreht der elektronisch angesteuerte Motor das Antriebsrad in der entsprechenden Richtung bis die Fadenzubringer ihre Endstellungen vertauscht haben. Die Fadenzubringer verbleiben in ihrer Endstellung so lange, bis mustergemäß ein anderer Schussfaden eingewoben werden muß.The device consists of a housing with a flanged electric motor, preferably a stepper motor or DC motor. A drive wheel is rotatably arranged on the motor shaft. A deflection wheel is attached to the housing below the drive wheel. A belt, preferably a toothed belt, or a roller chain wraps around the two wheels. A thread feeder is attached to each of the two belt strands so that one thread feeder is in the ready position, while the other is in the transfer position. If the thread feeders have to change their end positions, the electronically controlled motor turns the drive wheel in the corresponding direction until the thread feeders have reversed their end positions. The thread feeders remain in their end position until another weft thread has to be woven in according to the pattern.

Sind mehr als zwei verschiedene Schussfäden für den Webprozeß notwendig, wird die Zuführvorrichtung nur mit einem Fadenzubringer eingesetzt, jedoch für jeden Schussfaden eine Vorrichtung. Es ist aber auch möglich bei mehr als zwei verschiedenen Schussfäden die Zuführvorrichtung mit je zwei Fadenzubringer elektronisch so anzusteuern, daß drei Halte- und Ruhestellungen für die Fadenzubringer entstehen, dadurch für z.B. acht Schussfäden nur vier Zuführvorrichtungen benötigt werden. Bei dieser Mehrfachanordnung von Zuführvorrichtungen ist bei einer Zuführvorrichtung immer ein Fadenzubringer in der Übergabestellung, der andere Fadenzubringer in der Bereitschaftsstellung "Hoch", während die Fadenzubringer der andern Zuführvorrichtung in der Position Bereitschaftsstellung "Mitte", wo sich die Fadenösen kreuzen, verbleiben und keine Schussfäden vom Schussfadeneintragungsorgan mitgenommen werden können. Jeder Fadenzubringer ist entsprechend dem mustergemäßen Steuerprogramm für die Elektomotoren in einer der drei Stellungen und wechseln die Stellungen im Verlauf des Webprozesses.If more than two different weft threads are necessary for the weaving process, the feed device is only used with one thread feeder, but one device for each weft thread. But it is also possible with more than two different weft threads to electronically control the feed device, each with two thread feeders, so that three holding and rest positions are created for the thread feeders, thereby for e.g. eight weft threads only four feeders are needed. With this multiple arrangement of feed devices, one thread feeder is always in the transfer position, the other thread feeder is in the standby position "high", while the thread feeders of the other feed device remain in the standby position "center", where the thread eyelets cross, and no weft threads can be taken away by the weft insertion organ. Each thread feeder is in one of the three positions according to the model control program for the electric motors and changes the positions during the weaving process.

Während dem Webprozeß werden durch ein Schusseintragorgan 15 Schussfäden 17 von Vorratsspulen 16 abgezogen und in das Webfach eingetragen. Die Auswahl und die Vorlage der Schussfäden 17 erfolgt mustergemäß durch elektronische Ansteuerung des Elektromotors 2, welcher am Gehäuse 1 befestigt ist und auf der Motorwelle 3 ein damit formschlüssig verbundenes Antriebsrad 4 hat. Das Umlenkrad 5 ist drehbar am Gehäuse 1 befestigt und der Achsabstand und die Durchmesserdifferenz von Antriebsrad 4 und Umlenkrad 5 ist so bemessen, daß die verlängert gedachten geraden Riementrums des umschlingenden Riemens 6 sich in der Übergabestellung U schneiden. Am schlupffrei laufenden Riemen 6 sind mittels Befestigungselementen 8 die Fadenzubringer 7,7a angebracht die, geführt durch die Führung 10, parallel zu den Riementrums laufen. Die Schussfäden 17,17a gleiten durch die Fadenösen 9 der Fadenzubringer 7,7a.During the weaving process, weft threads 17 are drawn from supply bobbins 16 by a weft insertion member and inserted into the shed. The selection and the presentation of the weft threads 17 is carried out according to the pattern by electronic control of the electric motor 2, which is fastened to the housing 1 and has a drive wheel 4 connected to it in a form-fitting manner on the motor shaft 3. The deflection wheel 5 is rotatably fastened to the housing 1 and the center distance and the difference in diameter of the drive wheel 4 and the deflection wheel 5 are dimensioned such that the elongated straight belt strand of the looping belt 6 intersects in the transfer position U. On the non-slip belt 6, the thread feeders 7, 7a are attached by means of fastening elements 8 and, guided by the guide 10, run parallel to the belt runs. The weft threads 17, 17a slide through the thread eyelets 9 of the thread feeders 7, 7a.

Wie in Fig. 2 dargestellt, ist z.B. der Fadenzubringer 7 mit der Fadenöse 9 und Schussfaden 17 in der Übergabestellung U während Fadenzubringer 7a mit der Fadenöse 9 mit Schussfaden 17a in der Bereitschaftsstellung B sich befindet. Muß mustergemäß der Schußfaden 17a in die Übergabestellung U gebracht werden, wird der Elektromotor 2 entsprechend angesteuert und das Antriebsrad 4 treibt den Riemen 6 an und bewegt den Fadenzubringer 7a mit dem Schussfaden 17a in die Übergabestellung U, während der Fadenzubringer 7 zwangsläufig in die Bereitschaftsstellung B zurück fährt. Das Kreuzen der Schussfäden 17,17a erfolgt auf halbem Weg mit gegenseitigem Abstand, so daß ein gegenseitiges Verhängen der Fäden ausgeschlossen ist.As shown in FIG. 2, for example, the thread feeder 7 with the thread eyelet 9 and weft thread 17 is in the transfer position U while thread feeder 7a with the thread eyelet 9 with weft thread 17a is in the standby position B. If the weft 17a must be brought into the transfer position U according to the pattern, the electric motor 2 is controlled accordingly and the drive wheel 4 drives the belt 6 and moves the thread feeder 7a with the weft thread 17a into the transfer position U, while the thread feeder 7 inevitably into the standby position B. drives back. The weft threads 17, 17a are crossed halfway with a mutual distance so that the threads do not hang together.

Muß aus mehr als zwei verschiedenen Schussfäden ausgewählt werden, sind entsprechend mehr Vorrichtungen einzusetzen. Dabei ist das Ansteuerprogramm für die Elektromotoren so programmiert, daß von allen eingesetzten Vorrichtungen nur der mustergemäße Fadenzubringer in der Übergabestellung U ist, während alle anderen Fadenzubringer in der Bereitschaftsstellung B' sind, wie in Fig. 3 dargestellt, bzw. ein Fadenzubringer in der Bereitschaftstellung B ist.If more than two different weft threads have to be selected, more devices must be used accordingly. The control program for the electric motors is programmed in such a way that of all the devices used, only the sample thread feeder is in the transfer position U, while all other thread feeders are in the standby position B ', as shown in FIG. 3, or one thread feeder is in the standby position B is.

Fig. 4 zeigt eine Vorrichtung mit gleichgroßen Durchmessern von Antriebsrad 4 und Umlenkrad 5 und parallel zueinander laufenden Fadenzubringern 14,14a. Die Fadenzubringer 14,14a sind zwischen zwei Riemen 12,12a in der Ebene 11 der Riemenzugfasereinlagen 13 angeordnet und mittels der Befestigungselemente 8 daran formschlüssig festgeklemmt. Durch die gemeinsame Bewegungsebene von Riemen und Fadenzubringer entstehen keine Biege- und Kippmomente infolge Beschleunigungs- und Verzögerungskräfte, hervorgerufen durch die Fadenzubringerbewegungen, auf die Riemen. Eine zusätzliche Führung für die Fadenzubringer ist bei dieser Anordnung nicht notwendig. Es kann ein Fadenzubringer pro Vorrichtung eingesetzt werden, oder deren zwei.4 shows a device with the same size diameters of drive wheel 4 and deflection wheel 5 and thread feeders 14, 14a running parallel to one another. The thread feeders 14, 14a are arranged between two belts 12, 12a in the plane 11 of the belt pull fiber inlays 13 and are clamped to them in a form-fitting manner by means of the fastening elements 8. Due to the common plane of movement of the belt and the thread feeder, there are no bending and tilting moments as a result of acceleration and deceleration forces caused by the thread feeder movements on the belt. An additional guide for the thread feeder is not necessary with this arrangement. One thread feeder per device, or two, can be used.
