Dabei wird vorteilhaft der Abstand des Wartungswagens zur Spindel mit mindestens einem induktiven Sensor mit der Spindel als Referenz gemessen. Dies hat den Vorteil eines einfachen und kostengünstigen Aufbaus. Der Wartungswagen kann auf einfache Weise beim kleinsten Abstand des induktiven Sensors in einer Wartungsposition zur Spindel zentriert positioniert werden, wobei der kleinste Abstand als absoluter Abstandwert oder durch Ableitung einer vom induktiven Sensor ausgenommenen Abstandskurve bestimmt wird. Sofern die Ableitung Null ist, befindet sich der Wartungswagen zentriert vor der Spindel. Die zentrale Positionierung ist wichtig für die korrekte Ausrichtung des Wartungswagens.In this case, the distance of the maintenance trolley to the spindle is advantageously measured with at least one inductive sensor with the spindle as a reference. This has the advantage of a simple and inexpensive construction. The service trolley can be positioned in a simple way centered at the smallest distance of the inductive sensor in a maintenance position to the spindle, wherein the smallest distance is determined as an absolute distance value or by deriving a distance from the inductive sensor distance curve. If the derivative is zero, the maintenance trolley is centered in front of the spindle. The central positioning is important for the correct alignment of the maintenance trolley.
Vorteilhaft ist es zusätzlich möglich, beim Entlangfahren des Wartungswagens die Anzahl der Spindeln durch den mindestens einen induktiven Sensor zu zählen, und entsprechend kann auch die Position des Wartungswagens an der Ringspinnmaschine bestimmt werden.Advantageously, it is also possible to count the number of spindles by the at least one inductive sensor when driving along the maintenance trolley, and accordingly, the position of the maintenance trolley on the ring spinning machine can be determined.
Zur exakten und zentrierten Positionierung des Wartungswagens, wird dieser mit mindestens zwei und vorzugsweise mit drei Geschwindigkeiten betrieben, die stufenweise hintereinander folgen. Es gibt eine höhere Geschwindigkeit zur groben Positionierung des Wartungswagens vor einer Spindel. Sofern der Wartungswagen die Spinnstelle mit dem Fadenbruch kennt, wird er sich mit dieser erhöhten Geschwindigkeit an die Position bewegen. Im Abschnitt vor der Spindel wird der Wartungswagen mit einer kleineren Vorpositionierungsgeschwindigkeit zum Annähern an eine Spindel bewegt. Im letzten Abschnitt wird der Wartungswagen mit einer Mikropositionsgeschwindigkeit vor der Spindel zentriert positioniert. In einer alternativen Ausführungsform wird die Geschwindigkeit des Wartungswagens kontinuierlich von der höheren Geschwindigkeit zur groben Positionierung des Wartungswagens in Form einer Rampe zur Mikropositionsgeschwindigkeit hinuntergefahren. Auf beide Weisen ist es vorteilhaft möglich, den Wartungswagen präzise zentriert vor der Spindel zu positionieren.For exact and centered positioning of the maintenance trolley, this is operated with at least two and preferably with three speeds, which follow one after the other in stages. There is a higher speed for coarse positioning of the maintenance trolley in front of a spindle. If the maintenance trolley knows the spinning position with the thread breakage, it will move to this position at this increased speed. In the section in front of the spindle, the service trolley is moved at a smaller pre-positioning speed for approaching a spindle. In the last section, the maintenance trolley is centered at a microposition speed in front of the spindle. In an alternative embodiment, the speed of the maintenance cart is continuously reduced from the higher speed to the coarse positioning of the maintenance cart in the form of a ramp to the microposition speed. In both ways, it is advantageously possible to position the maintenance trolley precisely centered in front of the spindle.
Der Wartungswagen ist entsprechend zur Messung des Abstands zur Spindel mit einer Auswerteelektronik ausgestattet ist, die Signale der Sensoren auswertet, um den kleinsten Abstand absolut oder durch Ableitung einer Abstandskurve zu bestimmen oder zu berechnen. Die Auswerteelektronik ist weiter dazu da, um beim Entlangfahren des Wartungswagens die Anzahl der Spindeln zu zählen und die Position des Wartungswagens zu bestimmen.The maintenance trolley is equipped with an evaluation electronics for measuring the distance to the spindle, which evaluates signals from the sensors to determine the smallest distance absolute or by deriving a distance curve or calculate. The evaluation electronics are also there to count the number of spindles and to determine the position of the maintenance trolley as the maintenance trolley moves by.
