Abstract

The yarn brake assembly has a guide tube (8) opening coaxially into the brake housing (1). It can be locked in place in the brake housing at a number of height level positions, and carries a spring-loaded support body (5). A yarn entry tube (16) is within the guide tube, and can be locked in at least two positions against the guide tube. It carries a brake ring (14) at the inner end, with a sprung support against the support body. The yarn brake assembly has a guide tube with an angled surface at its upper edge, with a shaped projection. The yarn entry tube has a bead (16.1) projecting outwards, with a lower angled surface matching the upper edge of the guide tube. The lower edge of the bead has a number of recesses, with the base of each at a different gap from the upper edge of the entry tube. The support body has a number of support shoulders (5.1,5.2) at axial intervals around its circumference, to lie against a radial projection (1.1) at the inner wall of the housing. The support body has a bowl shape with a cylinder chamber (5.3) as a sprung support for the brake ring. A second brake ring (4) is held at a carrier (3) which acts as a piston within the brake housing, with movement against a return spring (2) to release the brake cartridge. Radial projections at the inner wall of the housing are supports (20) for the brake cartridge (11) where the cartridge bulges (13.1).

Description

Die Erfindung betrifft eine Fadenbremse, insbesondere für Doppeldraht-Zwirnspindeln bzw. Doppeldraht-Zwirnmaschinen, mit einem im wesentlichen rohrförmigen Bremsengehäuse, in dem eine kapselförmige Bremspatrone angeordnet ist, die erste und zweite teleskopartig gegen Federkraft gegeneinander verschiebbare Hülsenteile aufweist, die im wesentlichen kugelige bzw. kalottenförmige, entgegengesetzt gerichtete Endabschnitte zur Bildung von Bremsflächen haben, die gegen im Bremsengehäuse starr und/oder in Achsrichtung verschiebbar gelagerte, federbelastete Bremsringe anliegen, deren Abstand voneinander veränderbar ist. The invention relates to a thread brake, in particular for double-wire twisting spindles or double-wire twisting machines, with an essentially tubular brake housing, in which a capsule-shaped brake cartridge is arranged, the first and has second sleeve parts telescopically displaceable against spring force, the essentially spherical or dome-shaped, oppositely directed Have end sections for the formation of braking surfaces that oppose in the brake housing Rigid and / or axially displaceable, spring-loaded brake rings apply, the distance from which can be changed.

Insbesondere zum Einsatz in Doppeldraht-Zwirnspindeln sind Bremsen bekannt, die aus einem Bremsengehäuse bestehen, durch welches der Faden axial hindurchgeführt wird. Die Eintritts- und Austrittsöffnungen des eigentlichen Bremsbereichs sind jeweils durch Bremsringe mit konischer Bremsfläche gebildet. Sie bestehen in der Regel aus einem Material mit hoher Abriebfestigkeit. Zwischen den einzelnen einlauf- und auslaufseitig angeordneten Bremsringen erstreckt sich als der eigentliche Bremskörper eine Bremspatrone aus zwei im wesentlichen zylindrischen Hülsenteilen, die teleskopartig ineinander gesteckt sind und kugelige bzw. kalottenförmige Enden aufweisen. Die Hülsen schließen eine Druckfeder ein, die beim Einsetzen der Bremspatrone in das Bremsengehäuse durch Zusammendrücken der beiden Hülsenteile gespannt wird, so daß die kalottenförmigen Enden der Hülsenteile in Abhängigkeit von der Einstellung der Bremse auf die Bremsringe denjenigen Bremsdruck ausüben, den der jeweils durchlaufende Faden erfordert Je nach Größe des erforderlichen Bremsdrukkes werden entsprechend stärkere oder schwächere Federn in die Bremspatrone eingesetzt.Brakes are known in particular for use in double-wire twisting spindles consist of a brake housing through which the thread is passed axially becomes. The entry and exit openings of the actual braking area are each formed by brake rings with a conical braking surface. They usually exist made of a material with high abrasion resistance. Between the individual inlet and Brake rings arranged on the outlet side extend as the actual brake body a brake cartridge made of two essentially cylindrical sleeve parts, which are telescopic are inserted into each other and have spherical or dome-shaped ends. The sleeves include a compression spring, which is used when inserting the brake cartridge clamped in the brake housing by compressing the two sleeve parts is so that the dome-shaped ends of the sleeve parts depending on the Adjust the brake on the brake rings exert the brake pressure that the continuous thread required Depending on the size of the required brake pressure accordingly stronger or weaker springs are inserted into the brake cartridge.

Zur Veränderung bzw. Einstellung der Bremskraft ist es entsprechend der DE 43 43 458 C2 (= US 5,581,988) und der DE 44 08 262 C2 (= US 5,487,263) bekannt, den oberen Bremsring bzw. den diesen tragenden Bremsringträger zur Veränderung des Abstandes zum unteren Bremsring in unterschiedlichen Höhenstellungen zu fixieren. Bei der Fadenbremse gemäß DE 43 43 458 C2 ist der untere Bremsring stationär im Bremsengehäuse gelagert, während der obere Bremsring zur Verstellung der Bremskraft in unterschiedlichen Höhenstellungen arretierbar ist. Aus der DE 44 08 262 C2 ist es weiterhin bekannt, den unteren Bremsring bzw. seinen Träger entgegen der Kraft einer Rückstellfeder mittels Unterdruck von dem oberen Bremsring weg zu verstellen, so daß sich die unter dem Einfluß der Schwerkraft nach unten bewegende Bremspatrone auf Stützelementen abstützen kann, die von der Innenwand des Bremsengehäuses nach innen vorspringen. Die Bremspatrone verliert damit den Kontakt mit den oberen und unteren Bremsringen, so daß ein Durchfädeln des Fadens durch die Fadenbremse ermöglicht wird.To change or adjust the braking force, it is according to the DE 43 43 458 C2 (= US 5,581,988) and DE 44 08 262 C2 (= US 5,487,263) known to change the upper brake ring or the brake ring carrier carrying this the distance to the lower brake ring at different heights to fix. In the thread brake according to DE 43 43 458 C2 is the lower brake ring stored stationary in the brake housing, while the upper brake ring for adjustment the braking force can be locked in different height positions. From DE 44 08 262 C2 it is also known to counter the lower brake ring or its carrier the force of a return spring by means of negative pressure away from the upper brake ring to adjust so that it is under the influence of gravity moving brake cartridge can be supported on support elements by the inner wall of the brake housing protrude inwards. The brake cartridge thus loses the Contact with the upper and lower brake rings, so that threading the thread is made possible by the thread brake.

Der in Anspruch 1 beschriebenen Erfindung liegt die Aufgabe zugrunde, bei einer Fadenbremse der eingangs geschilderten Art einfache und wirksame Möglichkeiten zur Veränderung der Bremskraft zu schaffen. The invention described in claim 1 is based on the object Thread brake of the type described simple and effective options to change the braking force.

    Durch Hochziehen und Verdrehen des Fadeneinlaufrohres 16 kann man die Nase 23 in eine bestimmte Aussparung 22 einrasten lassen und damit die Höhenstellung des Bremsringträgers innerhalb des napfartigen Stützkörpers 5 verändern.By pulling up and turning the thread inlet tube 16, the nose 23 in snap a certain recess 22 and thus the height of the Change the brake ring carrier within the cup-like support body 5.

    Zwischen den Bremsringen 4 und 14 ist eine kapselförmige Bremspatrone 11 abgestützt, die aus zwei teleskopartig ineinander gefiigten Hülsenteilen 12 und 13 zusammengesetzt ist. Das untere Hülsenteil 12 hat im wesentlichen die Form einer Zylinderhülse mit einem unteren kugeligen oder kalottenartigen Endabschnitt. Das zweite obere Hülsenteil 13 ist ebenfalls aus einer Zylinderhülse hergestellt, die in ihrem Mittelabschnitt eine Ausbauchung 13.1 und an ihrem oberen Ende einen kugeligen oder kalottenartigen Endabschnitt aufweist.A capsule-shaped brake cartridge 11 is supported between the brake rings 4 and 14, which are composed of two telescopic sleeve parts 12 and 13 is.
