Abstract
Description
Die Erfindung betrifft eine Spinnmaschine mit einer Vielzahl von Spinnstellen, die jeweils eine mit Unterdruck arbeitende Verdichtungszone zum Verdichten eines Faserverbandes aufweisen, sowie mit einer Mehrzahl von den Unterdruck erzeugenden Lüftern, die jeweils mehreren Spinnstellen zugeordnet sind, wobei jeder Lüfter eine Überwachungseinrichtung aufweist, der eine mit dem Unterdruck zusammenhängende Betriebsgröße des Lüfters zugeordnet ist.The The invention relates to a spinning machine having a plurality of spinning stations, each one working with negative pressure compression zone for Have compression of a fiber structure, as well as a plurality from the vacuum generating fans, each associated with a plurality of spinning stations, each fan a monitoring device has, associated with a related to the negative pressure operating size of the fan is.

Spinnmaschine dieser Art ist aus der
In der Praxis hat es sich gezeigt, dass die Verstopfungen jedoch häufig nicht in den die Saugluft zum Lüfter führenden Bauteilen, sondern im Lüfter und insbesondere am Lüfterrad selbst auftreten. Solche Verstopfungen führen zu einer Schwergängigkeit des Lüfterrades, die von der bekannten Überwachungseinrichtung nicht erkannt werden kann, da sich die Leistungsaufnahme des Lüfters nicht verringert, und somit die Spannung des Antriebsriemens nicht nachlässt.In In practice, it has been shown that the blockages, however, often not in the suction air to the fan leading Components, but in the fan and especially on the fan occur yourself. Such blockages lead to a binding of the Fan wheel, that of the known monitoring device can not be detected because the power consumption of the fan is not reduced, and thus the tension of the drive belt does not deteriorate.
Der Erfindung liegt die Aufgabe zu Grunde, eine Überwachungseinrichtung für die Lüfter einer Spinnmaschine der eingangs genannten Art zu schaffen, die einen durch Schwergängigkeit des Lüfterrades hervorgerufenen Unterdruckabfall in der Verdichtungszone detektieren kann.Of the The invention is based on the object, a monitoring device for the fan of a spinning machine to create the type mentioned, the one by stiffness of the fan wheel detected negative pressure drop in the compression zone can.
Die Aufgabe wird dadurch gelöst, dass die von der Überwachungseinrichtung überwachte Betriebsgröße die Lüfterdrehzahl ist.The Task is solved by that monitored by the monitoring device Operating variable the fan speed is.
Dabei geht die Erfindung von der Erkenntnis aus, dass bei einer Verstopfung im Lüfter oder am Lüfterrad selbst die Lüfterwelle schwergängig wird und sich nur noch mit erhöhtem Kraftaufwand drehen lässt. Die Lüfterwelle wird abgebremst und der durch das Lüfterrad geförderte Volumenstrom wird geringer. Dadurch steht in der Verdichtungszone nicht mehr der benötigte Unterdruck zur Verfügung.there The invention is based on the recognition that in case of constipation in the fan or on the fan even the fan shaft sluggishly will and only with increased Turning force. The fan shaft is decelerated and the volume flow delivered by the fan wheel is reduced. As a result, the required negative pressure is no longer present in the compression zone to disposal.

Neben dem Vorteil, eine Schwergängigkeit des Lüfterrades detektieren zu können, hat die erfindungsgemäße Überwachungseinrichtung den Vorteil, eine Verstopfung in den die Saugluft zum Lüfter führenden Bauteilen feststellen zu können. Bei einer solchen Verstopfung ist nicht eine geringer werdende Lüfterdrehzahl die Ursache für einen geringeren Volumenstrom, sondern eine durch die Verstopfung hervorgerufenen Querschnittsverringerung. Hierbei bewirkt der nachlassende Volumenstrom eine geringere Leistungsaufnahme des Lüfters, wodurch sich – insbesondere bei einzelmotorisch angetriebenen Lüftern – die Lüfterdrehzahl erhöht.Next the advantage of a binding of the fan wheel to be able to detect has the monitoring device according to the invention the advantage of a blockage in the suction air leading to the fan Be able to determine components. With such a blockage is not a decreasing fan speed the cause of a lower volume flow, but one through the blockage caused cross-sectional reduction. This causes the declining Flow rate lower power consumption of the fan, thereby reducing yourself - in particular for single engine driven fans - increases the fan speed.
Eine Überwachung der Lüfterdrehzahl ist wesentlich einfacher möglich, als eine direkte Messung und Überwachung des Unterdrucks, da Unterdrucksensoren aufwändig justiert werden müssen.A surveillance the fan speed is much easier possible as a direct measurement and monitoring the negative pressure, since vacuum sensors must be adjusted consuming.
Es ist vorteilhaft, die Überwachungseinrichtung mit Sensoren auszurüsten, die die Lüfterdrehzahl berührungslos und somit ohne zusätzliche Reibungsverluste erfassen können. Dabei können diese Sensoren dem Lüfterrad oder der Lüfterwelle zugeordnet sein. Wenn die Sensoren der Lüfterwelle zugeordnet sind, ist es vorteilhaft, der Überwachungseinrichtung einen drehfest auf der Lüfterwelle befestigten Signalgeber zuzuordnen, der ein sich proportional mit der Lüfterdrehzahl veränderndes Signal erzeugt.It is advantageous, the monitoring device equipped with sensors, the fan speed contactless and thus without additional Can detect friction losses. It can these sensors are the fan or the fan shaft be assigned. If the sensors are assigned to the fan shaft, it is advantageous to the monitoring device a rotationally fixed on the fan shaft attached to a signal generator, which is proportional to the fan speed changing Signal generated.
