  • traveling blowers Such a traveling blower is equipped with a tube extending over the height of the gate. Starting from this tube, horizontal tubes extend, each of which blows a disc brake.

Description

Die Erfindung bezieht sich auf eine Tellerbremse für Textilfäden, mit einer vertikalen hohlen Tellerachse, die zwei Bremsteller abstützt und in einer an einem Bremsenträger befestigten Lagerplatte schwenkverstellbar lagert, welche die Tellerachse oberhalb des Bremsenträgers und unterhalb des oberen Bremstellers außen umgibt.The invention relates to a disc brake for textile threads, with a vertical hollow disc axis, which supports two brake actuators and is pivotally mounted in a bearing plate fastened to a brake carrier, which surrounds the disc axis above the brake carrier and below the upper brake actuator on the outside.

Eine Tellerbremse mit den vorgenannten Merkmalen ist aus EP 0 529 429 A1 bekannt. Die bekannte Tellerachse ist oszillierend schwenkbar angetrieben, damit sich ein Bremsteller oder beide Bremsteller der Tellerbremse hin- und herbewegen. Es soll erreicht werden, daß sich Flusen u.dgl. im Bereich der Bremsteller nicht festsetzen können, wie das bei stillstehenden Bremstellern oder umlaufangetriebenen Bremstellern der Fall wäre. Faserstoffansammlungen würden die Bremskraft beeinträchtigen. Das kann bei der Tellerbremse mit den eingangs genannten Merkmalen auf vielfältige Weise geschehen. Wenn sich im Hohlraum der hohlen Tellerachse Faserstoffansammlungen bilden, kann das dazu führen, daß der Oberteller und das darüber angeordnete Belastungselement angehoben werden. Somit bricht die einstellbare Fadenzugkraft zusammen. Der von dieser Tellerbremse gebremste Textilfaden hat nicht die erforderliche Spannung und wird infolgedessen von der eine Vielzahl von Textilfäden von einem Spulengatter abziehenden Wickelmaschine mit zu geringer Spannung aufgewickelt. Es entsteht eine entsprechende Störung des Wickelaufbaus und gegebenenfalls auch des Abwickelbetriebs, z.B. beim Stillsetzen der Wickelmaschine.A disc brake with the aforementioned features is known from EP 0 529 429 A1. The known plate axis is driven to oscillate and pivot so that one brake actuator or both brake actuators of the plate brake move back and forth. It should be achieved that fluff and the like. cannot fix in the area of the brake actuators, as would be the case with stationary brake actuators or rotary brake actuators. The accumulation of fiber would impair the braking force. This can be done in a variety of ways with the disc brake with the features mentioned at the beginning. If fiber accumulations form in the hollow of the hollow plate axis, this can lead to the upper plate and the load element arranged above it being raised. The adjustable thread tension breaks down. The textile thread braked by this disc brake does not have the required tension and is consequently wound with too little tension by the winding machine pulling a large number of textile threads from a creel. There is a corresponding disturbance in the winding structure and possibly also in the unwinding operation, for example when the winding machine is stopped.

Größere Faserstaubansammlungen hat man bisher durch den Einsatz von Wandergebläsen bekämpft. Ein solches Wandergebläse ist mit einem über die Höhe des Gatters reichenden Rohr ausgestattet. Von diesem Rohr ausgehend erstrecken sich horizontale Rohre, die jeweils eine Tellerbremse beblasen. Die Beblasung erfolgt diskontinuierlich, da das Wandergebläse horizontal von vertikaler Tellerbremsreihe zu vertikaler Tellerbremsreihe verschoben werden muß. Infolgedessen ist eine kontinuierliche Beblasung aller Tellerbremsen nicht möglich. Vielmehr hängt die Dauer der Beblasung von der Länge des Spulengatters und von der Geschwindigkeit des Wandergebläses ab. Letzteres stört den Arbeitsablauf, wenn in seinem Bereich ein Faden repariert werden oder eine Spule ausgewechselt werden muß. Darüber hinaus wird das Problem der inneren Reinigung von Tellerbremsen durch ein solches von außen erfolgendes Beblasen nicht gelöst.Larger fiber dust accumulations have so far been combated by the use of traveling blowers. Such a traveling blower is equipped with a tube extending over the height of the gate. Starting from this tube, horizontal tubes extend, each of which blows a disc brake. The blowing takes place discontinuously, since the traveling blower has to be moved horizontally from the vertical plate brake row to the vertical plate brake row. As a result, continuous inflation of all disc brakes is not possible. Rather, the duration of the blowing depends on the length of the creel and on the speed of the traveling blower. The latter disrupts the workflow when a thread has to be repaired in its area or a bobbin has to be replaced. In addition, the problem of cleaning the disc brakes internally is not solved by such external blowing.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Tellerbremse mit den eingangs genannten Merkmalen so zu verbessern, daß Verschmutzungen und insbesondere innere Verschmutzungen vermieden werden.The invention is therefore based on the object of improving a disc brake with the features mentioned at the outset in such a way that soiling and in particular internal soiling are avoided.

Diese Aufgabe wird dadurch gelöst, daß die Tellerachse und die Lagerplatte mindestens einen Luftkanal aufweist bzw. aufweisen, der einerseits an eine Druckluftquelle angeschlossen ist und der andererseits an Faserstaub-Sammelstellen im Bereich des Untertellers mündet.This object is achieved in that the plate axis and the bearing plate have or have at least one air duct which is connected on the one hand to a compressed air source and on the other hand opens at fiber dust collection points in the area of the saucer.

Für die Erfindung ist von Bedeutung, daß die Tellerachse und die Lagerplatte einen Luftkanal aufweisen, mit dem unter den Unterteller geblasen werden kann. Für die Beblasung des Untertellers erfolgt also eine spezielle Ausbildung der Tellerbremse im Bereich ihrer Tellerachse und im Bereich ihrer Lagerplatte. Dadurch wird es ermöglicht, den Faserstaub unterhalb des Untertellers an denjenigen Stellen wegzublasen, an denen er durch eine globale Beblasung der Tellerbremse von oben oder durch eine globale Beblasung der Tellerbremse von unten nicht zu entfernen wäre. Die Beblasung der Tellerbremse im Bereich des Untertellers kann der Konstruktion der Tellerbremse angepaßt werden. Es ist daher im Grundsatz möglich, jede beliebige Stelle der Tellerbremse faserstofffrei zu halten.It is important for the invention that the plate axis and the bearing plate have an air channel with which it is possible to blow under the saucer. For the blowing of the saucer there is therefore a special design of the plate brake in the area of its plate axis and in the area of its bearing plate. This makes it possible to blow away the fiber dust below the saucer at those points at which it would not be possible to remove it from the top by blowing the plate brake globally or from below by blowing the plate brake globally. The blowing of the disc brake in the area of the saucer can be the construction of the disc brake be adjusted. In principle, it is therefore possible to keep any point on the disc brake free of fiber.

Für die Ausgestaltung der Tellerbremse im einzelnen ist es von Bedeutung, daß diese im wesentlichen rotationssymmetrisch ist. Infolgedessen ist es von Vorteil, die Tellerbremse so auszubilden, daß der Luftkanal eine abgedichtete Ringnut der Tellerachse ist, die vertikale, direkt unter dem Unterteller mündende Austrittsöffnungen aufweist. Infolge der Ringnut des Luftkanals kann an alle erforderlichen Stellen der Tellerbremse geblasen werden. Das wird durch eine geeignete wahlweise Positionierung der Austrittsöffnungen erreicht.For the design of the disc brake in detail, it is important that it is essentially rotationally symmetrical. As a result, it is advantageous to design the disc brake in such a way that the air duct is a sealed annular groove on the disc axis, which has vertical outlet openings which open directly under the saucer. As a result of the annular groove in the air duct, the plate brake can be blown to all required points. This is achieved through a suitable optional positioning of the outlet openings.

Um ein kontrolliertes Abfließen der unter den Unterteller geblasenen Luft zu erreichen und um zugleich zu bewirken, daß der Hohlraum der Tellerachse gereinigt wird, wird die Tellerbremse so ausgebildet, daß die Unterseite des Untertellers und der Hohlraum der Tellerachse luftströmungsmäßig miteinander verbunden sind.In order to achieve a controlled flow of the air blown under the saucer and at the same time to cause the cavity of the plate axis to be cleaned, the plate brake is designed such that the underside of the saucer and the cavity of the plate axis are connected to one another in terms of air flow.

Die Tellerbremse kann so ausgestaltet werden, daß ein den Unterteller nachgiebig abstützender poröser Ring von den Austrittsöffnungen des Luftkanals mit Druckluft durchblasen ist. Infolgedessen werden Staubansammlungen im Bereich dieses Rings vermieden. Der Ring kann nicht verhärten. Ein solches durch Staubansammlungen bedingtes Verhärten des Rings würde dazu führen, daß der Unterteller nicht mehr oder nicht mehr hinreichend ausweichen könnte, wenn Fadendickstellen oder Fadenknoten durch die Bremsteller laufen. Eine Verhärtung des Rings würde zu Fadenbrüchen führen. Die Fadenbruchgefahr wird durch die Druckluftreinigung des porösen Rings vermieden.The disc brake can be designed in such a way that a porous ring which resiliently supports the saucer is blown with compressed air from the outlet openings of the air duct. As a result, dust accumulation in the area of this ring is avoided. The ring cannot harden. Such hardening of the ring due to the accumulation of dust would lead to the saucer no longer or not being able to deflect sufficiently if thread thickening points or thread knots run through the brake plates. Hardening of the ring would lead to thread breaks. The risk of thread breakage is avoided by cleaning the compressed air of the porous ring.

Wenn die Tellerbremse so ausgebildet wird, daß sich an die Ringnut radiale, außerhalb des den Unterteller abstützenden Rings zwischen diesem und der Lagerplatte mündende Blasöffnungen anschließen, so wird die Tellerbremse nicht nur tellerachsinnenseitig gereinigt, sondern auch im Bereich zwischen der Tellerachse und der sie umgebenden Lagerplatte. Der bauliche Aufwand durch die zusätzlichen Blasöffnungen ist gering.If the disc brake is designed in such a way that radial openings outside the ring supporting the saucer between the saucer and the bearing plate connect to the annular groove, the disc brake is not only cleaned on the inside of the plate axis, but also in the area between the plate axis and the surrounding bearing plate . The construction effort due to the additional blowing openings is low.

Um die Ringnut von außen her mit Druckluft zu versorgen, ist die Tellerbremse so ausgebildet, daß der Luftkanal in der Lagerplatte radiale Zuluftschlitze zur Luftzuleitung in die Ringnut hat. Über die Anzahl und die Verteilung der Zuluftschlitze kann die Druckluftversorgung der Ringnut auch bei geringen Querschnittsabmessungen ohne erhebliche Drosselverluste versorgt werden.In order to supply the annular groove with compressed air from the outside, the disk brake is designed in such a way that the air channel in the bearing plate has radial supply air slots for supplying air to the annular groove. The compressed air supply to the ring groove can be supplied without significant throttling losses even with small cross-sectional dimensions via the number and distribution of the air slots.

Um eine Beblasung des Raums zwischen der Tellerachse und der sie umgebenden Lagerplatte zu intensivieren, ist die Tellerbremse so ausgebildet, daß die Zuluftschlitze mit Blasbohrungen verbunden sind, die außerhalb des den Unterteller abstützenden Rings zwischen diesen und die Lagerplatte blasen.In order to intensify a blowing of the space between the plate axis and the bearing plate surrounding it, the plate brake is designed in such a way that the supply air slots are connected to blow holes which blow outside the ring supporting the saucer between them and the bearing plate.

Eine weitere grundsätzliche Möglichkeit zur Innenreinigung der Tellerbremse ist gegeben, wenn der Luftkanal in der Lagerplatte einen Ringkanal für die Druckluftverteilung zum Beblasen des Untertellers aufweist. Von einem solchen Ringkanal aus könnte der zwischen der Tellerachse und der sie umgebenden Lagerplatte vorhandene Raum der Tellerbremse direkt beblasen werden, ohne daß es dazu einer Ringnut in der Tellerachse bedürfte. Der Ringkanal der Lagerplatte ist jedoch auch für die Druckluftversorgung der Tellerachse von Vorteil.A further basic possibility for cleaning the inside of the plate brake is provided if the air duct in the bearing plate has an annular duct for the compressed air distribution for blowing the saucer. From such an annular channel, the space of the disk brake between the disk axis and the bearing plate surrounding it could be blown directly without the need for an annular groove in the disk axis. However, the ring channel of the bearing plate is also advantageous for the compressed air supply to the plate axis.

Um die Druckluftversorgung der Ringnut der Tellerachse sicherzustellen, ist die Tellerbremse so ausgebildet, daß der Ringkanal der Lagerplatte mit der Ringnut der Tellerachse über die Zuluftschlitze verbunden ist. Es ergibt sich eine baulich einfache Anordnung.In order to ensure the compressed air supply to the ring groove of the plate axis, the plate brake is designed such that the ring channel of the bearing plate is connected to the ring groove of the plate axis via the supply air slots. The result is a structurally simple arrangement.

Die Tellerbremse kann so ausgestaltet werden, daß in einem horizontalen, für weitere Tellerbremsen bestimmten Bremsenträger eine Luftspeiseleitung angeordnet ist, die vertikale Verbindungsbohrungen zu den Ringkanälen der Lagerplatten der Tellerbremsen aufweist. Es wird die zentrale Druckluftversorgung einer Vielzahl von Tellerbremsen erreicht, denen eine gemeinsame Luftspeiseleitung zugeordnet ist. Die Anordnung der Luftspeiseleitung im Bremsenträger ermöglicht eine konstruktiv einfache Ausgestaltung der gesamten Druckluftversorgung, da der Bremsenträger ohne weiteres eine Luftspeiseleitung in Gestalt von Druckluftleitungen aufnehmen kann, falls er nicht selbst so ausgebildet ist, daß eine Hohlkammer die Luftspeiseleitung bildet.The disc brake can be designed such that an air feed line is arranged in a horizontal brake carrier intended for further disc brakes, which has vertical connecting bores to the ring channels of the bearing plates of the disc brakes. The central compressed air supply to a large number of disc brakes, to which a common air supply line is assigned, is achieved. The arrangement of the air feed line in the brake carrier enables a structurally simple configuration of the entire compressed air supply, since the brake carrier easily has an air feed line in the form of compressed air lines, if it is not itself designed so that a hollow chamber forms the air feed line.

Eine Weiterbildung der Tellerbremse liegt dadurch vor, daß der Luftspeiseleitung eine weitere parallel angeordnete Luftspeiseleitung zugeordnet ist, die mit der ersten Luftspeiseleitung verbunden und/oder mit elastischen Blasrohren versehen ist, die jeweils eine Tellerbremse einer tiefer liegenden Spulenetage beblasen. Die weitere, parallele Luftspeiseleitung verbessert die Druckluftversorgung der Tellerbremse bei entsprechend bemessener, druckkonstanter Druckluftquelle oder sie ermöglicht eine Gesamtbeblasung einer weiteren Tellerbremse insbesondere von oben.A further development of the disk brake is that the air feed line is assigned a further parallel air feed line, which is connected to the first air feed line and / or is provided with elastic blowpipes, each of which blows a disk brake on a lower-lying coil level. The further, parallel air feed line improves the compressed air supply to the disk brake with a suitably dimensioned, pressure-constant compressed air source, or it enables total blowing of another disk brake, in particular from above.

Um eine Zentralversorgung der Lufteinspeisung zweckmäßig auszugestalten, ist die Tellerbremse so ausgebildet, daß die Luftspeiseleitung an einem Ende und/oder im Bereich von Feldstößen des Spulengatters eingespeist ist.In order to appropriately design a central supply of the air feed, the plate brake is designed such that the air feed line is fed in at one end and / or in the region of field impacts of the coil creel.

Die Erfindung wird anhand eines Ausführungsbeispiels erläutert. Es zeigt:

The invention is explained using an exemplary embodiment. It shows:
Fig. 1
a cross section through a disc brake with the internal cleaning provided according to the invention, and
Fig. 2
two stacked disc brakes of a vertical row of creel.

Der dargestellte Faden 11 wird von einer nicht dargestellten Spule eines Spulengatters in Richtung des Pfeils 11' mit einer Wickelmaschine abgezogen, beispielsweise mit einer Schärmaschine oder mit einer Zettelmaschine. Der Faden 11 durchläuft dabei die Tellerbremse 10, die ihm die zum Aufwickeln erforderliche Fadenspannung erteilt. Die Tellerbremse 10 hat einen oberen Teller 14, der auf einem unteren Teller 26 aufliegt. Beide bilden mit den ersichtlichen Abflachungen einen Tellerspalt 35, durch den der Faden 11 in und durch die Tellerbremse 10 gezogen wird.The thread 11 shown is drawn off from a spool (not shown) of a creel in the direction of arrow 11 'with a winding machine, for example with a warping machine or with a warping machine. The thread 11 passes through the plate brake 10, which gives it the thread tension required for winding. The plate brake 10 has an upper plate 14 which rests on a lower plate 26. Both form a disc gap 35 with the visible flats, through which the thread 11 is drawn into and through the disc brake 10.

Die Teller 14,26 sind schalenförmige Blechpreßteile, deren äußere Schalenränder parallel zu einer Mittelachse 41 nach oben bzw. nach unten weisen. Außerdem haben die Teller 14,26 durch den äußeren Rändern parallele Innenränder gebildete Innenausnehmungen 14',26', so daß die Teller 14,26 eigentlich ringförmig sind.The plates 14, 26 are shell-shaped pressed sheet metal parts, the outer shell edges of which point upwards or downwards parallel to a central axis 41. In addition, the plates 14, 26 have inner recesses 14 ', 26' formed by inner edges parallel to the outer edges, so that the plates 14, 26 are actually annular.

Eine Tellerbremse 10 ist mit ihren Tellern 14,26 auf einem sich horizontal erstreckenden Bremsenträger 12 angeordnet, der gemäß Fig.1 den dort beispielsweise dargestellten F-förmigen Querschnitt hat. Oberhalb dieses Bremsenträgers 12 bzw. direkt auf diesem aufliegend ist eine Lagerplatte 36 vorgesehen, die mit Abwinkelungen 39 Fadenösen 40 trägt, welche auf Höhe des Tellerspalts 35 angeordnet sind und infolge der dargestellten Gegenüberanordnung den Durchlaufbereich des Fadens 11 durch die Fadenbremse 10 festlegen.A disk brake 10 is arranged with its disks 14, 26 on a horizontally extending brake carrier 12 which, according to FIG. 1, has the F-shaped cross section shown there, for example. Above this brake carrier 12 or lying directly on it, a bearing plate 36 is provided which bears 39 thread eyelets 40 with bends, which are arranged at the level of the plate gap 35 and, as a result of the opposite arrangement shown, define the passage area of the thread 11 through the thread brake 10.

Die Lagerplatte 36 trägt eine Tellerachse 13 zur Abstützung der Teller 14,26. Die Abstützung erfolgt mit einem nachgiebigen Ring 28, beispielsweise einem Schaumstoffring. Infolgedessen kann der untere Teller 26 nach unten ausweichen, falls ein Knoten des Fadens 11 durchläuft. Andererseits ist dieser Ring 28 steif genug, um die erforderlichen, von einer Andruckeinrichtung 20 auf den oberen Teller 14 ausgeübten Andruckkräfte abstützen zu können.The bearing plate 36 carries a plate axis 13 for supporting the plates 14, 26. The support is provided with a flexible ring 28, for example a foam ring. As a result, the lower plate 26 can deflect downward if a knot of the thread 11 passes. On the other hand, this ring 28 is stiff enough to be able to support the necessary pressure forces exerted by a pressure device 20 on the upper plate 14.

Der nachgiebige Ring 28 muß seinerseits direkt oder indirekt auf der Tellerachse 13 abgestützt werden. Hierzu ist die Tellerachse 13 mit der Lagerplatte 36 zusammengebaut, auf welcher Lagerplatte der Ring 28 abgestützt werden könnte. Das wäre bei einer Ausbildung der Tellerbremse 10 ohne Antrieb zur Fadenreinigung der Fall. Die Abstützung des Rings 28 erfolgt jedoch indirekt über eine Lagerwelle 25, mit der der untere Teller 26 über den Ring 28 drehangetrieben werden soll. Hierzu hat die Lagerwelle 25 ein Wellenende 25', das den Bremsenträger 12 quer durchsetzt. Die Abstützung der Lagerwelle 25 erfolgt jedoch nicht direkt am Bremsenträger 12, sondern in einer von der Lagerplatte 36 gebildeten Lagerausnehmung 24, die von einem Ringvorsprung 42 der Lagerplatte 36 gebildet wird. Diese Lagerausnehmung 24 ist oberhalb des Bremsenträgers 12 und innerhalb der Lagerplatte 36 radial so erweitert, daß die Lagerwelle 25 den Ring 28 mit einer Außenumfangsnut 25'' so aufnehmen kann, daß der Ring 28 radial Abstand von der benachbarten Lagerplatte 36 hat, relativ zu der er sich dreht.The compliant ring 28 must in turn be supported directly or indirectly on the plate axis 13. For this purpose, the plate axis 13 is assembled with the bearing plate 36, on which bearing plate the ring 28 could be supported. That would be the case if the disk brake 10 were designed without a drive for thread cleaning. However, the ring 28 is supported indirectly via a bearing shaft 25 with which the lower plate 26 is to be driven in rotation via the ring 28. For this purpose, the bearing shaft 25 has a shaft end 25 'which passes through the brake carrier 12 transversely. However, the bearing shaft 25 is not supported directly on the brake carrier 12, but in a bearing recess 24 formed by the bearing plate 36, which is formed by an annular projection 42 of the bearing plate 36. This bearing recess 24 is above the brake carrier 12 and radially expanded within the bearing plate 36 so that the bearing shaft 25 can receive the ring 28 with an outer circumferential groove 25 "such that the ring 28 is radially spaced from the adjacent bearing plate 36, relative to which it rotates.

Zum Antrieb der Lagerwelle 25 dient eine trägerparallele Changierstange 27, die vertikal zur Darstellungsebene hin- und herbewegt werden kann. Das Ausmaß der Bewegung ist so bemessen, daß sich der untere Teller 26 um mehr als 360° dreht. Infolgedessen werden die meisten Fadenabriebteile mit Sicherheit abgestreift, ohne daß sich im Bereich der Teller Klumpen bilden können. Außerdem wird ein Verschleiß des Tellerpaares verhindert. Der Eingriff der Changierstange 27 erfolgt mit einem Zahnstangenstück 27' in die Verzahnung 25''' des Lagerwellenendes 25'.A carrier-parallel traversing rod 27, which can be moved back and forth vertically to the plane of the illustration, is used to drive the bearing shaft 25. The extent of the movement is such that the lower plate 26 rotates by more than 360 °. As a result, most of the thread abrasion parts are removed with certainty without lumps forming in the area of the plates. Wear on the pair of plates is also prevented. The traversing rod 27 engages with a toothed rack piece 27 'in the toothing 25' '' of the bearing shaft end 25 '.

Der Antrieb der Lagerwelle 25 wirkt mittels des Ringes 28 nur auf den unteren Teller 26. Damit auch der obere Teller 14 in gleichem Maße hin- und hergehend schwenkangetrieben wird, ist eine Feder 29 vorhanden, die aus einem Drahtstück gebildet ist. Dessen eines Ende sitzt federnd klemmend in der hohl ausgebildeten Lagerwelle 25. Der Innendurchmesser der hohlen Lagerwelle 25 ist so groß bemessen, daß der radial in Richtung auf den Bremsenträger 12 vorspringende innere Tellerrand in die Lagerwelle 25 eingreifen kann. Das andere Ende des Drahtstücks greift in den oberen Teller 14 ein. Beispielsweise sei auch auf die diesbezügliche Beschreibung der EP 0 529 429 A1 hingewiesen.The drive of the bearing shaft 25 acts by means of the ring 28 only on the lower plate 26. So that the upper plate 14 is pivoted back and forth to the same extent, a spring 29 is provided, which is formed from a piece of wire. One end of which resiliently sits in the hollow bearing shaft 25. The inside diameter of the hollow bearing shaft 25 is dimensioned so large that the inner plate rim projecting radially in the direction of the brake carrier 12 can engage in the bearing shaft 25. The other end of the piece of wire engages in the upper plate 14. For example, reference is also made to the relevant description of EP 0 529 429 A1.

Zur Erzeugung einer Bremskraft wird der obere Teller 14 auf den unteren Teller 26 gedrückt. Eine Andruckeinrichtung 20 ist ebenfalls in der EP 0 529 429 A1 beschrieben, worauf hiermit Bezug genommen wird.To generate a braking force, the upper plate 14 is pressed onto the lower plate 26. A pressure device 20 is also described in EP 0 529 429 A1, to which reference is hereby made.

Die in den Fig.1,2 dargestellten Tellerbremsen 10 sind jeweils so ausgebildet, daß sie einen Luftkanal 50 aufweisen, mit dem ein oder mehrere Faserstaub-Sammelstellen 51 im Bereich des Untertellers 26 beblasen werden können. Als Beispiel für eine solche Faserstaub-Sammelstelle 51 ist der Hohlraum 55 anzusehen. Der Luftkanal 50 ist in den Fig.1,2 mit durchgehenden dünnen Strichen gekennzeichnet, welche den Verlauf des Luftkanals 50 unterhalb des Untertellers 26 veranschaulichen. Die Pfeile der dünnen Linien symbolisieren die Mündungsstellen des Luftkanals 50.The plate brakes 10 shown in FIGS. 1, 2 are each designed such that they have an air channel 50 with which one or more fiber dust collecting points 51 in the area of the saucer 26 can be blown. The cavity 55 can be seen as an example of such a fiber dust collecting point 51. The air duct 50 is continuous in FIGS marked thin lines, which illustrate the course of the air duct 50 below the saucer 26. The arrows of the thin lines symbolize the mouths of the air duct 50.

Der Luftkanal 50 weist im Bereich der Tellerachse 13 bzw. in der Lagerwelle 25 eine Ringnut 52 auf, die gegenüber der Lagerplatte 36 in nicht dargestellter Weise abgedichtet ist. Von der Ringnut 52 erstrecken sich über den Umfang der Tellerachse 13 gleichmäßig verteilte axiale bzw. vertikale Austrittsöffnungen 53, die direkt an der Unterseite 54 des Untertellers 26 münden. Von dieser Unterseite 54 strömt die Luft in den Hohlraum 55 der Tellerachse 13. Sofern für die luftströmungsmäßige Verbindung der Durchtrittsquerschnitt zwischen dem inneren Tellerrand des Untertellers 26 und dem oberen Ende 63 der Lagerwelle 25 nicht groß genug ist, können hier schlitzartige Verbindungsöffnungen 64 vorgesehen werden, die in nicht dargestellter Weise gleichmäßig über den Innenumfang der Lagerwelle 25 verteilt sind. Mit Hilfe der hier austretenden Druckluft kann sowohl die Unterseite 54 des Tellers 26 sauber geblasen werden, wie auch der Hohlraum 55 der Tellerachse 13.The air duct 50 has an annular groove 52 in the area of the plate axis 13 or in the bearing shaft 25, which is sealed with respect to the bearing plate 36 in a manner not shown. Extending from the annular groove 52 over the circumference of the plate axis 13 are uniformly distributed axial or vertical outlet openings 53 which open directly on the underside 54 of the saucer 26. The air flows from this underside 54 into the cavity 55 of the plate axis 13. If the passage cross-section between the inner plate edge of the saucer 26 and the upper end 63 of the bearing shaft 25 is not large enough for the air flow connection, slot-like connecting openings 64 can be provided here. which are evenly distributed over the inner circumference of the bearing shaft 25 in a manner not shown. With the help of the compressed air emerging here, both the underside 54 of the plate 26 can be blown clean, as can the cavity 55 of the plate axis 13.

Von der Unterseite 54 des Untertellers 26 strömt Druckluft auch in nicht dargestellter Weise durch den porösen Ring 28 und verhindert damit dessen Verhärtung durch Staubansammlungen. Der aus dem Ring 28 herausgeblasene Staub gelangt in einen Raum 65 zwischen Lagerwelle 25 und deren Ring 28 einerseits und die Lagerplatte 36 andererseits. Von hier aus wird etwaiger Staub darstellungsgemäß nach oben hinausgeblasen, wobei auch Blasöffnungen 56 vorhanden sein können, die die Ringnut 52 mit dem Raum 65 verbinden.Compressed air also flows from the underside 54 of the saucer 26 through the porous ring 28 in a manner not shown, thus preventing its hardening due to dust accumulation. The dust blown out of the ring 28 enters a space 65 between the bearing shaft 25 and its ring 28 on the one hand and the bearing plate 36 on the other. From here, any dust is blown upwards, as shown, whereby there may also be blowing openings 56 which connect the annular groove 52 to the space 65.

Zur Sauberhaltung der Innenteile der Bremse 10 strömt die Luft aus der Luftspeiseleitung 60 durch die Verbindungsbohrung 66 in den Ringkanal 59 der Lagerplatte 36. Von dort gelangt die Luft durch den oder die Zuluftschlitze 57 in den Ringraum 52 der Tellerachse 13. Der Ringraum 52 ist mit einer oder mehreren vertikalen Austrittsöffnungen 53 versehen. Aus den Austrittsöffnungen 53 strömt Luft gegen die Unterseite 54 des Untertellers 26 und wird dort umgelenkt und strömt einerseits in den Hohlraum 55 der Tellerachse 13 und andererseits durch den porösen Ring 28 in den Raum 65.In order to keep the inner parts of the brake 10 clean, the air flows from the air feed line 60 through the connecting bore 66 into the annular channel 59 of the bearing plate 36. From there, the air passes through the one or more supply air slots 57 into the annular space 52 of the plate axis 13. The annular space 52 is included one or more vertical outlet openings 53. Air flows out of the outlet openings 53 against the underside 54 of the saucer 26 and is deflected there and flows in on the one hand the cavity 55 of the plate axis 13 and on the other hand through the porous ring 28 into the space 65.

Um den Ringraum 52 mit Druckluft versorgen zu können, sind in der Lagerplatte 36 radiale Zuluftschlitze 57 vorhanden. Die Zuluftschlitze 57 sind ihrerseits von einem Ringkanal 59 der Lagerplatte 36 versorgt. Die Zuluftschlitze 57 sind gleichmäßig um den Umfang der Lagerplatte 36 herum verteilt und können mit Blasbohrungen 58 verbunden sein, die vom Ringkanal 59 mit kurzem Weg in den Raum 65 zwischen der Lagerplatte 36 und dem Ring 28 blasen, um eine wirkungsvolle Entfernung etwa vorhandenen Faserstaubs zu bewirken.In order to be able to supply the annular space 52 with compressed air, there are radial supply air slots 57 in the bearing plate 36. The supply air slots 57 are in turn supplied by an annular channel 59 of the bearing plate 36. The supply air slots 57 are evenly distributed around the circumference of the bearing plate 36 and can be connected to blowing bores 58 which blow from the ring channel 59 with a short distance into the space 65 between the bearing plate 36 and the ring 28 in order to effectively remove any fiber dust that may be present cause.

Der Ringkanal 59 der Lagerplatte 36 wird durch eine Ausnehmung gebildet, welche gegen den Bremsenträger 12 abgedichtet ist und über eine Bohrung 66 mit einer Luftspeiseleitung 60 in strömungsmäßiger Verbindung steht. Die Luftspeiseleitung 60 verläuft parallel innerhalb des Bremsenträgers 12 und ist selbst in nicht dargestellter Weise eingespeist.The annular channel 59 of the bearing plate 36 is formed by a recess which is sealed against the brake carrier 12 and is in flow connection with an air feed line 60 via a bore 66. The air feed line 60 runs parallel within the brake carrier 12 and is itself fed in in a manner not shown.

Parallel zur Luftspeiseleitung 60 ist eine weitere Luftspeiseleitung 61 dargestellt, die mit der Luftspeiseleitung 60 über eine Bohrung 67 in Verbindung stehen kann. Es ist dann möglich, beide Luftspeiseleitungen 60,61 zur Druckluftversorgung des Luftkanals 50 heranzuziehen und mit entsprechend großem Blasvolumen zu arbeiten. Die Luftspeiseleitung 61 kann aber auch dazu benutzt werden, ein Blasrohr 62 zu beaufschlagen, welches gemäß Fig.2 auf eine Tellerbremse 10' bläst, die unterhalb der Tellerbremse 10 angeordnet ist, wie Fig.2 zeigt. In diesem Fall sind die Luftspeiseleitungen 60,61 darstellungsgemäß nicht miteinander verbunden.A further air feed line 61 is shown parallel to the air feed line 60 and can be connected to the air feed line 60 via a bore 67. It is then possible to use both air feed lines 60, 61 to supply compressed air to the air duct 50 and to work with a correspondingly large blowing volume. The air feed line 61 can, however, also be used to apply a blowpipe 62 which, according to FIG. 2, blows onto a disk brake 10 ′ which is arranged below the disk brake 10, as shown in FIG. In this case, the air feed lines 60, 61 are not connected to one another as shown.

Die Einspeisung der Luftspeiseleitungen 60,61 erfolgt jeweils an deren Enden bzw. an einem ihrer Enden. Es ist aber auch möglich, feldweise einzuspeisen. Es wird dann jedes Feld eines Spulengatters separat versorgt, was beispielsweise dann von Vorteil ist, wenn am Spulengatter feldweise Spulenwechsel erfolgt. Die dargestellten Blasrohre 62 können elastisch ausgebildet sein und behindern infolgedessen das Arbeiten an den Spulstellen beim Spulenwechsel nicht. Bei feldweiser Einspeisung versteht es sich, daß die Luftspeiseleitungen 60,61 eines Felds an einem Feldstoß von den Luftspeiseleitungen 60,61 eines benachbarten Felds getrennt sein müssen. Die Einspeisung von Druckluft für ein Spulengatter insgesamt richtet sich nach den jeweiligen Bedürfnissen. Das Spulengatter kann kontinuierlich mit Druckluft versorgt werden, es kann aber auch stellenweise und/oder diskontinuierlich mit Druckluft versorgt werden. Die Wahl der jeweiligen Druckluftversorgung ist mit elektrischen Hilfsmitteln einstellbar.The air feed lines 60, 61 are fed in at their ends or at one of their ends. However, it is also possible to feed in fields. Each field of a creel is then supplied separately, which is advantageous, for example, if the coil creel is changed on a field-by-frame basis. The blowpipes 62 shown can be elastic and, as a result, do not hinder working on the winding stations when changing the bobbin. With field-wise feeding it is understood that the air feed lines 60, 61 of a field at a field joint must be separated from the air feed lines 60, 61 of an adjacent field. The total supply of compressed air for a creel depends on the respective needs. The creel can be supplied with compressed air continuously, but it can also be supplied with compressed air in places and / or discontinuously. The choice of the respective compressed air supply can be adjusted with electrical aids.

Diese Beschreibung trifft sinngemäß auch für Doppeltellerbremsen zu.This description also applies analogously to double-disc brakes.
