Abstract
Description
Anwendungsgebiet der ErfindungField of application of the invention
Die Erfindung betrifft ein Verfahren zur Vorgarnspannungsregelung an Flyern mit Einzelantrieben und bezieht sich auf das Gebiet der Vorgarnherstellung.The invention relates to a method for Vorgarnspannungsregelung on flyers with individual drives and refers to the field of Vorgarnherstellung.
Charakteristik der bekannten technischen LösungenCharacteristic of the known technical solutions
Es sind Flyer bekannt (DD-PS 217832), die mit je einem Antrieb für jede Spinnfunktion ausgestattet sind, die entsprechend den Spinngesetzen stufenlos regelbar und durch Qualitätsparameter beeinflußbar sind.There are flyers known (DD-PS 217832), which are each equipped with a drive for each spinning function, which are continuously adjustable according to the spinning laws and influenced by quality parameters.
Durch einen Mikrorechner werden die Qualitätsparameter des verarbeiteten Materials ausgewertet und zur Regelung der Antriebe verwendet. Verfahren zur Vorgarnspannungskorrektur an Flyern mit Einzelantrieben sind jedoch bisher nicht bekannt. Zur Fadenspannungskorrektur an Maschinen mit zentralem Antrieb werden Vorrichtungen mit einem federbelasteten Knickgelenk, welches von einer gekrümmten Führungsbahn gesteuert wird (DE-AS 2425174), oder Vorrichtungen, die mittels Nockenbahnen die Fadenspannung steuern, eingesetzt.The quality parameters of the processed material are evaluated by a microcomputer and used to control the drives. However, methods for Vorgarnspannungskorrektur on flyers with individual drives are not yet known. For thread tension correction on machines with central drive devices with a spring-loaded articulated, which is controlled by a curved guideway (DE-AS 2425174), or devices that control the thread tension by means of cam tracks, are used.
Weiterhin sind Korrektursteuersysteme (DE-OS1913055) bekannt.Furthermore, correction control systems (DE-OS1913055) are known.
Zur Realisierung dieser bekannten Lösungen ist ein hoher mechanischer Aufwand erforderlich und die Einstellung der Fadenspannungskorrektur ist nur durch Erfahrungswerte möglich. Weiterhin sind zur Erfassung der Fadenspannung mechanisch arbeitende Abtastelemente bekannt. Dabei wird durch Berührung der Faden mechanisch belastet. Diese Methode hat bei Vorgarn den Nachteil, daß es häufig zum Auflösen und damit zum Luntenbruch kommt. Alle diese Lösungen sind nicht für Flyer mit Einzelantrieb anwendbar.For the realization of these known solutions, a high mechanical complexity is required and the adjustment of the thread tension correction is possible only by empirical values. Furthermore, mechanically operating scanning elements are known for detecting the thread tension. This is mechanically loaded by touching the thread. This method has the disadvantage of roving that it often comes to dissolving and thus the Luntenbruch. All of these solutions are not applicable to single-drive flyers.
Ziel der ErfindungObject of the invention
Ziel der Erfindung ist es, ein Verfahren zu entwickeln, mit welchem die Vorgarnspannung geregelt werden kann.The aim of the invention is to develop a method with which the roving tension can be regulated.
Darlegung des Wesens der ErfindungExplanation of the essence of the invention
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Vorgarnspannungsregelung an Flyern mit Einzelantrieb zu schaffen, Erfindungsgemäß wird diese Aufgabe dadurch gelöst, indem durch den Meßwertaufnehmer die Fadenspannung des Fadens ermittelt wird und in Abhängigkeit von dieser Fadenspannung durch eine Auswerteeinheit die Einzelantriebe auf eine optimale Fadenspannung eingeregelt werden. Entsprechend der Lage des Fadens im Meßwertaufnehmer werden durch die Auswerteeinheit die Soll-Wert-Größen für die Motoren bereitgestellt. Diese Soll-Wert-Größen können bis zum Erreichen einer optimalen Fadenspannung einzeln oder verkoppelt durch die Auswerteeinheit variiert werden.The invention has for its object to provide a method for Vorgarnspannungsregelung on flyers with single drive, according to the invention this object is achieved by the tension of the thread is determined by the transducer and depending on this thread tension by an evaluation the individual drives to an optimum thread tension be adjusted. According to the position of the thread in the transducer, the setpoint values for the motors are provided by the evaluation unit. These setpoint value variables can be varied individually or coupled by the evaluation unit until an optimum thread tension is reached.

Ein Ausführungsbeispiel wird anhand der Figur 1 erläutert. Es zeigtAn embodiment will be explained with reference to FIG. It shows
Fig. 1: eine schematische Darstellung des funktionsbedingten Zusammenspiels der Baugruppen und Signale der Vorspinnmaschine.Fig. 1: a schematic representation of the function-related interaction of the modules and signals of the roving.
In dem Flyer sind die Motoren 1,2,11, die Einzelantriebe für die Flügel 7, Spulen 8 und das Streckwerk 9.In the flyer are the motors 1,2,11, the individual drives for the wings 7, 8 coils and the drafting. 9
Entsprechend der Lage des Fadens 10 im Meßwertaufnehmer 6 wird die Fadenspannung des Fadens 10 berührungslos ermittelt. Von dieser ermittelten Fadenspannung ausgehend werden durch die Auswerteeinheit 3 die Soll-Wert-Größen 4, 5,12 für die Motoren 1,2,11 bereitgestellt. Diese Soll-Wert-Größen 4,5,12 werden so lange durch die Auswerteeinheit 3 einzeln oder verkoppelt variiert, bis eine optimale Fadenspannung des Fadens 10 erreicht ist.According to the position of the thread 10 in the transducer 6, the thread tension of the thread 10 is determined without contact. Starting from this determined yarn tension, the evaluation unit 3 provides the desired value quantities 4, 5, 12 for the motors 1, 2, 11. These desired value quantities 4, 5, 12 are varied individually or coupled by the evaluation unit 3 until an optimum thread tension of the thread 10 has been reached.
