Description
Fadenbrernso für kleine SuFkrfte A thread burner for small visitors
Die vorliegende Erfindung betrifft ein Fadenbremse vorzugsweise für die Abbremsung von dünnsten Fäden in der Textilindustrie.The present invention relates to a thread brake preferably for the braking of the thinnest threads in the textile industry.
Einrichtungen dieser Art sind z. B. nach der GB - PS 9 98 987 und den deutschen Patenten 27 11 823 bzw. 27 52 019 sowie Anmeldung P 28 08 470 bekannt.Facilities of this type are z. B. according to GB - PS 9 98 987 and the German patents 27 11 823 and 27 52 019 and application P 28 08 470 known.
Diese bekannten rotierenden Fadenbremsen sind auf Wälzlagern gelagert, die aber für sehr geringe Fadenspannungen eine noch zu große Grundreibung besitzen und deren Fett schmierung bei Lagererwärmung unlconstante Reibwerte ergibt.These known rotating thread brakes are mounted on roller bearings, which, however, still have too great a basic friction for very low thread tensions and their grease lubrication results in inconsistent coefficients of friction when the bearings are heated.
Dieser Erfindung liegt die Aufgabe zugrunde, eine Fadenbremse zu schaffen, die für sehr feine Fäden genau definierte und konstante kleine Zugspannungen ab ca. 10 N erzeugt.This invention is based on the object of creating a thread brake, which is precisely defined and constant small tensile stresses for very fine threads approx. 10 N generated.
Die erfindungsgemäße Fadenbremse zeichnet sich dadurch aus, daß für die Lagerung der Fadenrolle eine spezielle Luftlagerung vorgesehen wird.The thread brake according to the invention is characterized in that for the storage of the thread reel is provided with a special air bearing.
Anhand der Abb. 1-3 wird die Erfindung im folgenden beispielhaft beschrieben.The invention is described below by way of example with the aid of FIGS. 1-3.
Abb, 1 zeigt einen Querschnitt durch die gesamte Fadenbremse.Fig. 1 shows a cross section through the entire thread brake.
Abb. 2 zeigt die bekannte Sonstruktion einer Fadenrolle mit inr Grunde eingelegtem Gummipolster das nach oben ausgerundet ist.Fig. 2 shows the well-known Sonstruktion of a thread roll with basic inserted rubber pad that is rounded upwards.
Abb. 3 ist eine Fadenrolle mit einem O-Ring, der mit hoher Vorspannung an den Flanken hängt.Fig 3 is a spool of thread with an O-ring that is pretensioned hangs on the flanks.
In Abb. 1 stellt 1 die rotationssymmetrische Fadenrolle dar. Der Luftschmierfilm entsteht bei Rotation des Trockenlagers 2 der Fadenrolle 1 auf der stehenden Welle 3 durch Selbstansaugen der Luft der, an geeigneter Stelle angeordnete, Bohrungen 4 der Welle 3. Die Luftlagerung 2-3 kann weiterhin durch einen zusätzlitzen Druckluftanschluf3 5 bei einem geringeii kurzzeitigen Vordruck im Trockeniager 2 schon einen Luftfilm beim Anfahren erhalten. Mit einem höheren, kurzen Luftdruckimpuls kann der rotierende Teil 1-2-2' achsial gegen eine stehende Scheibe 6, entgegen der Magnetkraft gepreßt werden, wodurch die Rotation z. B.In Fig. 1, 1 represents the rotationally symmetrical thread roll. The air lubricating film arises when the dry storage 2 of the thread roll 1 rotates on the standing shaft 3 by self-sucking the air of the holes arranged in a suitable place 4 of the shaft 3. The air bearing 2-3 can still be connected to an additional compressed air connection3 5 with a slight short-term pre-pressure in the drying store 2 already an air film received at start-up. With a higher, short pulse of air pressure, the rotating Part 1-2-2 'axially against a standing disk 6, pressed against the magnetic force be, whereby the rotation z. B.
bei Fadenbruch sofort gestoppt wird.is stopped immediately if the thread breaks.
Die achsiale Zugkraft der Magnete 7 wird durch die Spitze 8 einer Schraube 9 praktisc1l reibungsfrei aufgenommen, mit der sich auch der erforderliche Luftspalt 10 zwischen den Magneten 7 und der Bremsscheibe 11 einstellen läßt.The axial tensile force of the magnets 7 is through the tip 8 a Screw 9 was added practically without friction, with which the required Air gap 10 between the magnet 7 and the brake disc 11 can be adjusted.
ilei geringen Fadenzugspannungen niltzt auch eine bekannte Gummiein@@ge 2 im Rollengrund icic:Ii Abb. 2 nichts gegen das Rutschen des Fadens 13 in der Rolle. In Abb. 3 ist eine Methode dargestellt, bei der der faden 14 z. B. zwischen einem O-Ring 15 und einer Flanke 16 der Fadenrolle 1 geführt wird und der, infolge der Keilwirkung, auf keinen Fall durchrutschen kann.In the case of low thread tension, a well-known rubber band is also useful 2 in the roll base icic: Ii Fig. 2 nothing against the thread 13 slipping in the roll. In Fig. 3 a method is shown in which the thread 14 z. B. between a O-ring 15 and a flank 16 of the thread roll 1 is guided and, as a result of the Wedge effect, cannot slip through under any circumstances.
Hierbei können auch beide Flanken 16-16' dafür ausgenutzt werden. In Abb. 1 ist eine Flanke 17 der Fadenrolle 1 so ausgebildet, daß der O-Ring 15, der nicht unbedingt einen runden tuerschnitt haben muß, etwa zur Hälfte verdeckt ist (Einspurbetrieb). Bin radialer Schlitz 18 in dem Flankenteil 17 gestattet mit einem Messer den O-Ring 15 vor dem Wechseln aufzuschneiden.Both flanks 16-16 'can also be used for this purpose. In Fig. 1, a flank 17 of the thread roll 1 is designed so that the O-ring 15, which does not necessarily have to have a round door cut, about half covered is (single-track operation). A radial slot 18 in the flank part 17 is also permitted a knife to cut open the O-ring 15 before changing.
