Description

Die Erfindung betrifft eine Fadenspannungs-Regulierein­richtung für einen von einer Garnspule über Fadenleit­organe, Fadenspanner und Fadenbruchmelder zum Verarbei­tungsbereich einer Strickmaschine geführten Faden, mit einem Fadenspannungsmesser und einer in Abhängigkeit von der Anzeige des Fadenspannungsmessers automatisch ein­stellbaren Fadenbremse.The invention relates to a thread tension regulating device for a thread guided by a thread spool via thread guiding elements, thread tensioners and thread breakage detectors to the processing area of a knitting machine, with a thread tension meter and a thread brake that is automatically adjustable depending on the display of the thread tension meter.

Eine Reguliereinrichtung der eingangs genannten Art ist beispielsweise aus der US-PS 45 23 440 bekannt. Dort wird eine Fadenbremse mittels eines Elektromotors in ihrer Bremswirkung verstellt, wobei der Motor in Abhängigkeit von der Anzeige eines Fadenspannungsmessers entweder in der einen Drehrichtung zur Verstärkung der Bremswirkung oder in der anderen Drehrichtung zur Verminderung der Bremswirkung betrieben wird. Durch diese Bremswirkungs­regelung soll erreicht werden, daß für gleiche Gestrick­ stücke auch immer gleiche Fadenlängen verarbeitet werden, so daß auch gleiche Gestrickabmessungen gewährleistet wer­den können.
Es hat sich bei diesen Fadenspannungs-Reguliereinrichtun­gen aber herausgestellt, daß durch die vielen Fadenleit­organe und Fadenüberwachungsvorrichtungen, über welche ein Faden von einer Garnspule bis in den Arbeitsbereich einer Strickmaschine geleitet werden muß, starke Fadenspannung­schwankungen auftreten. Diese dauernden Fadenspannungs­schwankungen führen auch zu einer dauernden Anzeigetätig­keit des Fadenspannungsmessers, wenn man dessen Empfind­lichkeit nicht so stark herabsetzt, daß die angestrebte Wirkung der Einrichtung verlorengeht. Betreibt man den Fadenspannungsmesser in einem wünschenswerten Empfindlich­keitsbereich, muß die Fadenspannung an der Fadenbremse praktisch dauernd ausreguliert werden.A regulating device of the type mentioned is known for example from US-PS 45 23 440. There, a thread brake is adjusted in its braking effect by means of an electric motor, the motor being operated depending on the display of a thread tension meter either in one direction of rotation to increase the braking effect or in the other direction of rotation to reduce the braking effect. This braking effect control is intended to achieve the same knitted fabric Pieces always the same thread lengths are processed, so that the same knitted dimensions can be guaranteed.
However, it has been found in these thread tension regulating devices that strong thread tension fluctuations occur due to the many thread guiding devices and thread monitoring devices, via which a thread must be passed from a thread spool to the working area of a knitting machine. These constant thread tension fluctuations also lead to a permanent display activity of the thread tension meter if its sensitivity is not reduced so much that the desired effect of the device is lost. If you operate the thread tension meter in a desirable sensitivity range, the thread tension on the thread brake must be adjusted practically continuously.

Der Erfindung liegt die Aufgabe zugrunde, eine Fadenspan­nungs-Reguliereinrichtung der eingangs genannten Art so auszubilden, daß sie eine sicherere und genauere Nachregu­lierung der Bremskraft der einstellbaren Fadenbremse gewährleistet.The invention has for its object to provide a thread tension regulating device of the type mentioned in such a way that it ensures a safer and more accurate readjustment of the braking force of the adjustable thread brake.

Die gestellte Aufgabe wird bei der genannten Fadenspan­nungs-Reguliereinrichtung erfindungsgemäß dadurch gelöst, daß in Fadendurchlaufrichtung unmittelbar vor der automa­tisch einstellbaren Fadenbremse eine die dem Faden auf seinem Weg von der Garnspule bis zur Fadenbremse auferleg­ten Spannung aufhebende Fadenfördervorrichtung angeordnet ist und daß zwischen der Fadenbremse und dem in Faden­durchlaufrichtung nachgeordneten Fadenspannungsmesser ein an sich bekannter Fadenaufholspanner angeordnet ist. Vor­ teilhafterweise kann als Fadenfördervorrichtung ein auch an sich bekannter Fadenspeicherfournisseur vorgesehen sein.The stated object is achieved in the aforementioned thread tension regulating device according to the invention in that a thread conveying device which removes the tension imposed on the thread on its way from the thread spool to the thread brake is arranged in the thread passage direction immediately before the automatically adjustable thread brake and that between the thread brake and the in A thread tensioner known per se is arranged downstream of the thread flow direction. In front Partially, a thread storage feeder which is also known per se can be provided as the thread conveying device.

Bei der erfindungsgemäß ausgebildeten Fadenspannungs-Regu­liereinrichtung machen sich also auf den Faden auf seinem Weg von der Garnspule bis zur Fadenbremse einwirkende Widerstände nicht bemerkbar, weil diese Widerstände durch die Zwangsförderung des Fadens überwunden werden und die Fadenfördervorrichtung den Faden in Anpassung an die Arbeitsgeschwindigkeit der Maschine praktisch spannungs­frei der Fadenbremse zuleitet. Dies bedeutet, daß am Fadenspannungsmesser nur noch die Spannungsänderungen er­faßt werden müssen, die der Faden auf seinem Weg von der gesteuerten Fadenbremse bis zur Verarbeitungsstelle der Strickmaschine erfährt. Der Einsatz eines Fadenspeicher­fournisseurs hat dabei den Vorteil, daß die Fadenförder­vorrichtung wegen der gespeicherten Fadenlänge nicht so genau ein- und abgeschaltet werden muß wie ohne Fadenspei­cher.In the thread tension regulating device designed according to the invention, resistances acting on the thread on its way from the thread spool to the thread brake are not noticeable, because these resistances are overcome by the forced conveyance of the thread and the thread conveying device practically adapts the thread to the working speed of the machine fed tension-free to the thread brake. This means that only the tension changes that the thread undergoes on its way from the controlled thread brake to the processing point of the knitting machine have to be recorded on the thread tension meter. The use of a thread storage feeder has the advantage that the thread conveying device does not have to be switched on and off as precisely as without thread storage because of the stored thread length.

Vorteilhafterweise kann die automatisch einstellbare Bremse gleichzeitig die Fadenbremse bilden, die der dem Fadenspannungsmesser vorgeschaltete Fadenaufholspanner ohnehin aufweisen muß, damit beim Fadenaufholvorgang tat­sächlich nur Faden aufgeholt und nicht Faden aus dem Fadenspeicher nachgezogen wird.Advantageously, the automatically adjustable brake can at the same time form the thread brake, which the thread tensioner upstream of the thread tension meter must have anyway, so that only thread is actually caught and not thread is pulled from the thread store during the thread winding process.

Die Fadenspannungs-Reguliereinrichtung gemäß der Erfindung eignet sich insbesondere zum Einsatz an Flachstrickmaschi­nen, wobei die automatisch einstellbare Fadenbremse dem im Bereich eines Nadelbettendes angeordneten seitlichen Fadenaufholspanner zugeordnet wird. Alle erfindungswesent­ lichen Teile der Fadenspannungs-Reguliereinrichtung, näm­lich die Fadenfördervorrichtung, der Fadenspannungsmesser und die dem bekannten Fadenaufholspanner zugeordnete, automatisch einstellbare Fadenbremse lassen sich dabei auf einem gemeinsamen Anbauteil anordnen, mit welchem auch ältere Flachstrickmaschinen nachgerüstet werden können.The thread tension regulating device according to the invention is particularly suitable for use on flat knitting machines, the automatically adjustable thread brake being assigned to the lateral thread take-up tensioner arranged in the area of a needle bed end. All essential to the invention Lichen parts of the thread tension regulating device, namely the thread conveying device, the thread tension meter and the automatically adjustable thread brake associated with the known thread take-up tensioner can be arranged on a common attachment, with which older flat knitting machines can also be retrofitted.

Es hat sich herausgestellt, daß die Ansprechempfindlich­keit der Reguliereinrichtung merklich erhöht werden kann, wenn auch die Reibung des Fadens beim Durchlauf des Faden­spannungsmessers stark reduziert wird, indem er im Bereich des Fadenspannungsmessers über stationäre und über beweg­lich gelagerte Fadenleitrollen geführt wird, die in jeder Stellung der beweglichen Teile des Fadenspannungsmessers die Fadenspannung, die der Faden im Fadenspannungsmesser erfährt, praktisch konstant halten.It has been found that the response sensitivity of the regulating device can be increased significantly, even if the friction of the thread during the passage of the thread tension meter is greatly reduced, in that it is guided in the area of the thread tension meter via stationary and movably mounted thread guide rollers, which in any position Moving parts of the thread tension meter keep the thread tension experienced by the thread in the thread tension meter practically constant.

In der beiliegenden Zeichnung ist die Anordnung einer erfindungsgemäß ausgebildeten Fadenspannungs-Regulierein­richtung an einer Flachstrickmaschine mehr oder weniger stark schematisiert dargestellt.In the accompanying drawing, the arrangement of a thread tension regulating device designed according to the invention on a flat knitting machine is shown more or less schematically.

Die in der Zeichnung dargestellte Fadenspannungs-Regulier­einrichtung weist einen gemeinsamen Träger 10 auf, der am Maschinenrahmen 11 einer Flachstrickmaschine im Bereich des Endes eines der Nadelbetten 12 befestigbar ist. Am Träger 10 ist ein Fadenspeicherfournisseur 13 befestigt, der beispielsweise eine elektromotorisch antreibbare Fadenspeichertrommel 14 aufweist, auf welche eine bestimm­te Fadenlänge in einzelnen Windungen als Vorrat gehalten ist, die - kontinuierlich oder in Intervallen - über ver­schiedene Fadenleitorgane 15 und mindestens eine Faden­überwachungsvorrichtung 16 von einer auf einem Spulentisch 17 der Flachstrickmaschine angeordneten Fadenspule 18 ab­gezogen worden it. Von der Speichertrommel 14 des Faden­speicherfournisseurs 13 läßt sich der gespeicherte Faden praktisch widerstandsfrei über eine richtungssteuernde Fadenleitöse 19 nach unten abziehen, wo er in eine Faden­bremse 20 eines in bekannter Weise mit einem Schwenkarm 21 versehenen Fadenaufholspanners gelangt. Die Bremswirkung der Fadenbremse 20 läßt sich mittels eine Elektromotors 22 der in beiden Drehrichtungen betrieben werden kann, verändern.The thread tension regulating device shown in the drawing has a common carrier 10 which can be fastened to the machine frame 11 of a flat knitting machine in the region of the end of one of the needle beds 12. A thread storage feeder 13 is fastened to the carrier 10 and has, for example, a thread storage drum 14 that can be driven by an electric motor, on which a certain thread length is kept in stock in individual turns, which - continuously or at intervals - via different thread guide members 15 and at least one thread monitoring device 16 from one a spool table 17 of the flat knitting machine arranged bobbin 18 has been withdrawn. From the storage drum 14 of the thread storage feeder 13, the stored thread can be pulled down practically without resistance via a direction-controlling thread guide eyelet 19, where it arrives in a thread brake 20 of a thread take-up tensioner provided in a known manner with a swivel arm 21. The braking effect of the thread brake 20 can be changed by means of an electric motor 22 which can be operated in both directions of rotation.

Nach dem Fadenaufholspanner mit dem Schwenkarm 21 durch­läuft der Faden 25 auf seinem Weg zu einem Fadenführer 23 und weiter zur nicht näher bezeichneten Arbeitsstelle der Flachstrickmaschine einen Fadenspannungsmesser 24 passen­der Bauart. Im Fadenspannungsmesser wird der Faden 25 über stationäre Fadenleitrollen 26 und über mindestens eine unter der Fadenspannung bewegliche Fadenleitrolle 27 ge­leitet. Der Fadenspannungsmesser 24 liefert von der gemes­senen Spannung des Fadens 25 abhängige Steuersignale, mit denen der Elektromotor 22 der automatisch einstellbaren Fadenbremse 20 entweder in der einen Richtung zur Verstär­kung der Bremswirkung oder in der anderen Richtung zur Verminderung der Bremswirkung betätigt wird.After the thread take-up tensioner with the swivel arm 21, the thread 25 passes through a thread tension meter 24 of a suitable type on its way to a thread guide 23 and further to the unspecified work station of the flat knitting machine. In the thread tension meter, the thread 25 is guided over stationary thread guide rollers 26 and over at least one thread guide roller 27 which is movable under the thread tension. The thread tension meter 24 supplies control signals dependent on the measured tension of the thread 25, with which the electric motor 22 of the automatically adjustable thread brake 20 is actuated either in one direction to increase the braking effect or in the other direction to reduce the braking effect.

Am Fadenspannungsmesser 24 wird also nur die Spannung wirksam, die der Faden 25 durch die Verarbeitung des Fadens an der Verarbeitungsstelle der Strickmaschine und durch die Fadenführung über die Fadenbremse 20 und nach­geschaltete Fadenleitorgane erfährt.Only the tension that the thread 25 experiences through the processing of the thread at the processing point of the knitting machine and through the thread guidance via the thread brake 20 and downstream thread guide members is thus effective on the thread tension meter 24.
