Abstract
Description
Fadenbremse Thread brake
Zweck der Erfindung ist: eine einfache Konstruktion zum Aufwickeln von Fäden mit einstellbarer Zugkraft, sowie der programmierten Steuerung der Bremskraft über spezielle Sensoren, z.B. in Abhängigkeit von Fadengeschwindigkeit oder Spulenform.The purpose of the invention is: a simple construction for winding of threads with adjustable tension, as well as the programmed control of the braking force via special sensors, e.g. depending on the thread speed or the bobbin shape.
In der Patent-Anmeldung P 28 o8 470.o-26 ist eine Fadenbremse beschrieben worden, bei welcher der Fadenverlauf von einer Fadenrille zur Nächsten über eine Nebenrolle mit einer oder mehreren V-Rillen erfolgt.In the patent application P 28 o8 470.o-26 a thread brake is described been, in which the thread course from one thread groove to the next over a Supporting role is made with one or more V-grooves.
Vorliegende Erfindung nutzt das obige Prinzip der Fadenführung aus, ist aber auf geringen Aufwand in der Herstellung abgestellt.The present invention uses the above principle of thread guidance, but is geared towards low expenditure in production.
Ein mit zwei oder mehr Außenrillen 1-1' versehener leichter Fadenring 2 hat auf der Innenseite eine oder zwei Führungsbahnen 3 von beispielsweise halbkreisförmigem Profil, in der mindestens drei Bremsrollen 4 angeordnet sind, die mit gummiartigen elastischen Ringen 5 belegt sind und die mit einstellbarem Anpressdruck in dieser Laufbahn 3 abrollen, wenn der Fadenring 2 durch den abgezogenen Faden 6 rotiert, Abb. 1.A light thread ring provided with two or more outer grooves 1-1 ' 2 has one or two guide tracks 3 of, for example, semicircular shape on the inside Profile in which at least three brake rollers 4 are arranged, which are rubber-like elastic rings 5 are occupied and with adjustable contact pressure in this Roll off track 3 when the thread ring 2 rotates through the pulled thread 6, Fig. 1.
Die entstehende Walkarbeit wirkt als Bremse für die Fadenzugkraft. Der Querschnitt des Belages kann beliebig, z.B.The resulting flexing work acts as a brake for the thread tension. The cross-section of the covering can be arbitrary, e.g.
rund oder halbrund, sein, Abb. 2.round or semicircular, fig. 2.
Der Anpressdruck der Bremsrollen 4 wird über eine weiche Feder 7 eingestellt 8, damit Wärmeeinflüße des Fadenringes 2 oder des gummiartigen Rollenbelages 5 weitgehend ausgeglichen werden. Eine Bremsrolle 4' ist exzentrisch 9 gelagert, so daß ein von der Feder 7 beeinflußter, auf den Exzenter 9 wirkender Hebel 1o die Rolle 4' entsprechend der eingestellten Federzugkraft in die Laufbahn 3 drückt und durch Verdrängungsarbeit im Belag die Bremswirlnwng erzeugt.The contact pressure of the brake rollers 4 is set via a soft spring 7 8, so that heat effects of the thread ring 2 or the rubber-like roller covering 5 largely be balanced. A brake roller 4 'is mounted eccentrically 9, so that one of the spring 7 influenced, acting on the eccentric lever 1o the roller 4 'accordingly the set spring tensile force pushes into the raceway 3 and by displacement work the brake turbulence is generated in the lining.
An Stelle der weichen, ausgleichenden Feder 7 kann auch ein Blektromagnet 11 eingesetzt werden, der eine Regelung des Anpressdruckes durch einen programmierten Geber oder andere Seilsoren bewirkt, z.B. für unterschiedliche Fadengeschwindigkeit infolge konischer Aufwickelspulen. Er kann auch als induktiver Fadenzugkraftgeber verwendet werden.Instead of the soft, compensating spring 7, a sheet magnet can also be used 11 are used, the control of the contact pressure by a programmed Encoder or other rope sensors, e.g. for different yarn speeds due to conical take-up spools. It can also be used as an inductive thread tension generator be used.
Der Fadenring 2 hat zur Kühlung seitlich angeordnete Schlitze oder Bohrungen mit Geblsewir1ctiiig.The thread ring 2 has laterally arranged slots or for cooling Drilled holes with blower effective.
Er kann auch mit einer Abdeckung 13 versehen sein, in welche Kühlflügel 14- eingearbeitet sind.It can also be provided with a cover 13 into which cooling blades 14- are incorporated.
Anstelle von massivem Werkstoff ist der Fadenring 2 aus Kunststoff oder Blech herstellbar, Abb. 3.Instead of solid material, the thread ring 2 is made of plastic or sheet metal, Fig. 3.
Ein mit dem Exzenter 9 verbundener, mit einer Leitrolle 15 versehener Hebel 1o bewirkt, daß bei plötzlich auftretenden Lastspitzen die Bremsrolle 4' etwas gelüftet wird, wodurch die Bremskraft augenblicklich verringert wird. Die Bremsrollen 4.-4' können auch ohne Belag dann im Fadenring 2 laufen, wenn der Belag 16 in der inneren Rollenlaufbahn 3 des Fadenringes 2 iest eingebettet ist, Abb. 5.One connected to the eccentric 9 and provided with a guide roller 15 Lever 1o has the effect that the brake roller 4 'something in the event of sudden load peaks is released, whereby the braking force is reduced instantly. The brake rollers 4.-4 'can then run in the thread ring 2 without a coating if the coating 16 is in the inner roller track 3 of the thread ring 2 is embedded, Fig. 5.
In Abb. 6 ist eine dünnwandige elastische Auskleidung 17 der Laufbahn 3 dargestellt. Die Bremsrollen 18 sind hierbei glatt.In Fig. 6 is a thin-walled elastic lining 17 of the raceway 3 shown. The brake rollers 18 are smooth here.
Abb. 7 zeigt eine Bremsrolle 19 mit Kühlkanälen 20.Fig. 7 shows a brake roller 19 with cooling channels 20.
21 ist die Nebenrolle, die ein Wechseln des Fadens von einer Rille 1 zur anderen 1' ermöglicht.21 is the supporting role, which is changing the thread of a groove 1 to the other 1 'allows.
