Description
Die Erfindung betrifft eine Vorrichtung an einem Streckwerk einer Spinnereimaschine, insbesondere Strecke, Karde, Kämmmaschine, Lapwinder o. dgl., zum Verstrecken von einem oder mehreren Faserbändern, mit mindestens zwei hintereinander angeordneten Walzenpaaren, deren Oberwalzen durch Belastungsmittel gegen die Unterwalzen drückbar sind, mit mindestens einem Zylinder mit innerhalb eines Zylindergehäuses axial bewegbar angeordnetem be- und entlastbaren Kolben, von dem eine Kolbenstange zur Oberwalze hin ausgeht, bei der zur Feststellung der Position des Kolbens mit der Kolbenstange eine Sensoranordnung vorhanden ist, wobei auf der der Kolbenstange abgewandten Seite ein Schaltelement mit dem Kolben in Verbindung steht.The invention relates to a device on a drafting system of a spinning machine, in particular track, carding machine, combing machine, Lapwinder o. The like., For stretching one or more slivers, with at least two successively arranged pairs of rollers, the top rollers can be pressed by loading means against the lower rollers, with at least one cylinder with axially movable arranged within a cylinder housing and relieved piston, from which a piston rod to the upper roller out, in which for detecting the position of the piston with the piston rod, a sensor arrangement is present, wherein on the side facing away from the piston rod, a switching element communicating with the piston.
Bei einer bekannten Vorrichtung (
Bei Verwendung eines Druckmittelzylinders (Pneumatikzylinders) wird die Belastungskraft auf den Oberwalzen beim Ausfahren des Kolbens erzeugt. Beim Ausfahren wird ebenso die Schaltscheibe gegen einen Anschlag verfahren, also in eine definierte Position gebracht. Wickelt eine Walze, wird der Kolben in die entgegengesetzte Richtung gedrückt, und der Wickel wird durch die Bewegung der Schaltscheibe vom Näherungsschalter erkannt. Durch den definierten Anschlag ist die Wickelerkennung unabhängig vom Außendurchmesser der Oberwalzen. Sie muss nach dem Schleifen der Walzen nicht neu eingestellt werden. Eine Federung ist bei dieser Vorrichtung nicht einsetzbar. Bei Einsatz einer Federung würde die Belastungskraft der Oberwalzen durch das Vorspannen der Feder aufgebracht werden. Dies kann in Kombination mit einer Verriegelung der Streckwerksklappe geschehen. In diesem Fall wird der Kolben aber beim Aufbringen der Belastungskraft (Vorspannen der Feder) in den Zylinder hinein gedrückt und bei einem Wickel in gleicher Richtung verfahren. Es ist daher nicht möglich, die Schaltscheibe in bekannter Art gegen einen Anschlag zu fahren, um einen definierten Abstand der Schaltscheibe zum Näherungsschalter herzustellen.When using a pressure cylinder (pneumatic cylinder), the loading force is generated on the top rollers during extension of the piston. When extending the indexing disk is also moved against a stop, so brought into a defined position. If a roller winds, the piston is pushed in the opposite direction and the winding is detected by the movement of the indexing switch. Due to the defined stop, the winding detection is independent of the outer diameter of the top rollers. It does not have to be readjusted after grinding the rollers. A suspension is not applicable to this device. When using a suspension, the loading force of the top rollers would be applied by biasing the spring. This can be done in combination with a locking of the drafting system flap. In this case, however, the piston is pressed into the cylinder during application of the loading force (pretensioning of the spring) and moved in the same direction in the case of a winding. It is therefore not possible to drive the indexing disc in a known manner against a stop to produce a defined distance of the indexing disk to the proximity switch.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet, die insbesondere eine selbsteinstellende Wickelerkennung erlaubt und einen gewünschten Abstand des Schaltelements zum Schalter ermöglicht.The invention is therefore based on the object to provide a device of the type described above, which avoids the disadvantages mentioned, which in particular allows a self-adjusting winding detection and allows a desired distance of the switching element to the switch.
Die Lösung dieser Aufgabe erfolgt durch die kennzeichnenden Merkmale des Anspruchs 1.The solution of this object is achieved by the characterizing features of claim 1.
Durch den erfindungsgemäßen Einsatz einer magnetorheologischen Substanz, insbesondere eines Elastomers, ist eine abstandsunabhängige Kupplung geschaffen. Auf diese Weise ist eine Feder als Belastungselement einsetzbar. Ein besonderer Vorteil liegt in einer selbsteinstellenden Wickelerkennung.The use according to the invention of a magnetorheological substance, in particular of an elastomer, creates a gap-independent coupling. In this way, a spring can be used as a loading element. A particular advantage lies in a self-adjusting winding detection.

Die Erfindung wurde am Beispiel eines magnetorheologischen Elastomers dargestellt. Von der Erfindung umfasst ist auch eine magnetorheologische Flüssigkeit. Dies ist eine Suspension aus Ölen und magnetischen Partikeln, die ähnliche Eigenschaften wie das Elastomer besitzt, also Ihre Viskosität unter Einfluss eines Magnetfelds ändert. The invention has been illustrated using the example of a magnetorheological elastomer. Also included in the invention is a magnetorheological fluid. This is a suspension of oils and magnetic particles that has properties similar to those of the elastomer, which changes its viscosity under the influence of a magnetic field.
Die erfindungsgemäße Kupplung kann nicht nur für eine selbsteinstellende Wickelerkennung verwendet werden, sondern auch in anderen Anwendungen Platz finden. Bezugszeichenliste
