Abstract

The drive for the sley in a loom, with toggle levers on the sley and pedestals operated by the eccentric drive action of a cam disc, has a rotary speed controlled motor to power the shaft for the cam disc. The shaft pref. has a higher rotary speed when the sley is moved away from the fabric edge and when it is moved back to the fabric edge between the working positions and a rear position, than when the sley is at rest through the cam drive. ADVANTAGE - The mechanism allows high working speeds to be achieved on large looms, without affecting the time span required for the sley to be at rest

Description

Die Erfindung bezieht sich auf einen Antrieb für die Ladenbewegung eines Webstuhles gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a drive for the Loading movement of a loom according to the generic term of the main claim.

In der US-PS 37 49 137 wird ein gattungsbildender Antrieb beschrieben, bei welchem ein Exzentertrieb in Verbindung mit Kniehebeln eingesetzt wird. Diese bekannte Anordnung ermöglicht eine sehr große Laden­ ruhe, die auch bei schnell laufenden Webstühlen einen einwandfreien Eintrag des Schußfadens sicher­ stellt und dabei trotzdem eine hohe Laufruhe auf­ weist. Außerdem wird durch die Kombination von Knie­ hebel und angetriebener Kurvenscheibe die erforder­ liche hohe Anschlagskraft trotz Schonung des Kurven­ triebes erreicht. Die Rückholbewegung bei dieser be­ kannten Anordnung kann mittels eines Zugelementes erfolgen oder durch eine entsprechende Ausbildung des am Ständer angelenkten Kniehebels.In US-PS 37 49 137 is a generic Drive described, in which an eccentric drive is used in conjunction with toggle levers. These known arrangement allows a very large store rest even with fast running looms a correct entry of the weft thread and still runs smoothly points. In addition, the combination of knees lever and driven cam the required high impact force despite protecting the bends drive achieved. The return movement at this be known arrangement can by means of a tension element done or through appropriate training of the toggle lever articulated on the stand.

Bei sehr langen bzw. breiten Webstühlen, d. h. Web­ stühlen mit großer Gewebebreite, muß die Zeitspanne der Ladenruhe relativ groß sein, um sicherzustel­ len, daß der Webschützen über die ganze "große" Länge des Webstuhles den Schußfaden ungestört ein­ tragen kann. Bei den bekannten Antriebsmitteln für die Weblade führt dies dazu, daß der Antriebsmotor sicherstellen muß, daß die gewünschte Ladenruhe erzielt wird, wobei aber gleichzeitig die Zeit­ spanne, die von diesem Motor benötigt wird, um die Weblade aus der hinteren in die vordere Stellung bzw. aus der vorderen Stellung in die hintere Stel­ lung zu bringen, ebenfalls relativ groß ist, d. h. der Motor läuft entsprechend langsam. Dies bedingt, daß bei großen Webstühlen die Arbeitsgeschwindig­ keit niedrig ist.For very long or wide looms, i.e. H. Web chairs with a large fabric width, the period of time must the shop quiet should be relatively large to ensure len that the shooter over the whole "big" Length of the loom the weft undisturbed can carry. In the known drive means for the sley causes the drive motor must ensure that the desired quietness is achieved, but at the same time time span required by this engine to achieve the Sley from the rear to the front position  or from the front position to the rear position bring is also relatively large, d. H. the engine runs accordingly slowly. This requires that the work speed for large looms speed is low.

Der Erfindung liegt die Aufgabe zugrunde, auch bei großen Webstühlen eine hohe Arbeitsgeschwindigkeit zu erreichen, ohne auf die ausreichende Zeitspanne der Ladenruhe verzichten zu müssen.The invention is based, also with the task large looms a high working speed to achieve without the sufficient amount of time to have to do without the quietness of the shop.

Diese der Erfindung zugrundeliegende Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die die Kurvenscheibe antreibende Welle durch einen in seiner Drehzahl regelbaren Antrieb derart angetrie­ ben wird, daß die Welle eine höhere Umdrehungsge­ schwindigkeit aufweist, wenn die Weblade aus ihrer Stellung am Warenrand in die hintere Stellung bzw. aus der hinteren Stellung zum Warenrand geführt wird, als dann, wenn die Weblade aufgrund der Aus­ gestaltung der Kurvenscheibe stillsteht, d. h. in dem Bereich der Ladenruhe.This object underlying the invention will solved according to the invention in that the Cam driving shaft by an in its speed adjustable drive so driven ben is that the shaft has a higher rotation shows dizziness when the sley comes out of its Position on the edge of the goods in the rear position or led from the rear position to the edge of the goods than when the drawer due to the out design of the cam is stationary, d. H. in the area of shop quiet.

Derartige Motoren können elektrisch, pneumatisch oder hydraulisch arbeiten, wobei ein elektrischer Motor im Handel z. B. unter der Herstellerbezeich­ nung "Indramat A.C. Servo" bekannt ist.Such motors can be electrical, pneumatic or work hydraulically, with an electric Motor in trade z. B. under the manufacturer name "Indramat A.C. Servo" is known.

In der beigefügten Skizze ist in Form einer Kurve dargestellt, wie sich der Weg der Weblade in der Zeiteinheit verhält.The attached sketch is in the form of a curve shown how the path of the shop in the Unit of time behaves.

In der oberen Darstellung (Fig. 1) ist das zum Stand der Technik gehörende Antriebsverfahren dar­ gestellt, bei welchem beispielsweise die Bewegung der Weblade vom Warenrand in die hintere Stellung eine Zeitspanne von 0,5 Sek. benötigt, während der Ladenstillstand eine Zeitspanne von 1 Sek. beträgt und die Bewegung der Weblade aus der hinteren Stel­ lung in die vordere Stellung am Warenrand 0,5 Sek. benötigt.In the upper representation ( FIG. 1), the drive method belonging to the prior art is shown, in which, for example, the movement of the sley from the goods edge into the rear position requires a time period of 0.5 seconds, while the shop shutdown takes a time period of 1 Seconds and the movement of the sley from the rear position to the front position on the edge of the goods takes 0.5 seconds.

Bei der erfindungsgemäßen Anordnung gemäß der un­ teren Darstellung (Fig. 2) ist die Zeitspanne für die Ladenruhe wiederum eine Sekunde, aber die Zeitspanne, um die Weblade vom Warenrand in die rückwärtige Stellung und von der rückwärtigen Stellung zum Warenrand zu führen, beträgt jeweils 0,25 Sek.In the arrangement according to the invention according to the lower representation ( FIG. 2), the time period for the shop rest is again one second, but the time period for guiding the sley from the goods edge to the rear position and from the rear position to the goods edge is 0 in each case , 25 sec

Aus dieser Graphik wird ersichtlich, daß bei gleicher Ladenruhe, also gleicher Zeitspanne, die zur Verfügung steht, um den Durchlauf des Schützens störungsfrei zu gewährleisten, die Zeitspanne ver­ ringert wird, die bisher benötigt wurde, um die Web­ lade aus der einen Endstellung in die andere End­ stellung zu führen.This graph shows that at same shop quietness, that is, the same amount of time that is available to the shooter's pass to ensure trouble-free time ver that has so far been needed to the web load from one end position to the other end position to lead.
