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 plate axis, the two Brake plate supports and in a attached to a brake carrier Bearing plate swiveling, which supports the plate axis above the brake carrier and below the upper one Brakes outside surrounds.

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 out EP 0 529 429 A1 is known. The well-known plate axis is oscillating pivotally driven so that there is a brake plate or move both brake discs of the disc brake back and forth. It should be achieved that fluff and the like. in the field of Can not lock the brake plate, as that when stationary Brake actuators or rotary brake actuators of the Would be the case. The accumulation of fiber would impair the braking force. This can be done with the disc brake with the aforementioned Features happen in a variety of ways. If form fiber accumulations in the hollow of the hollow plate axis, this can lead to the top plate and the above arranged load element can be raised. Thus breaks the adjustable thread tension together. The one from this disc brake braked textile thread does not have the required Tension and, as a result, of a variety of textile threads with a winding machine pulling off a creel wound up to low tension. A corresponding one is created Fault in the winding structure and possibly also the Unwinding operation, e.g. 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.So far, one has had larger fiber dust accumulations through the Combats the use of traveling blowers. Such a blower is equipped with a tube extending over the height of the gate. Starting from this tube, horizontal ones extend Tubes that each blow a disc brake. The blowing takes place discontinuously because the traveling fan is horizontal from vertical disk brake row to vertical disk brake row must be moved. As a result, it is continuous It is not possible to blow all disc brakes. Rather depends the duration of the blowing on the length of the creel and on the speed of the traveling blower. The latter bothers the workflow when a thread repairs in its area or a bobbin needs to be replaced. Furthermore becomes the problem of the internal cleaning of disc brakes 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 a disc brake to improve with the features mentioned at the beginning, that pollution and especially internal pollution be 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 has at least one air duct or have, on the one hand connected to a compressed air source and on the other hand at fiber dust collection points in the Area of the saucer opens.

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 duct with which under the saucer can be blown. For blowing the The saucers are specially designed for the disc brake in the area of their plate axis and in the area of their Bearing plate. This allows the fiber dust below to blow off the saucer at those points which he caused by a global blowout of the disc brake above or through a global blowing of the disc brake from could not be removed below. The blowing of the disc brake in the area of the saucer, the construction of the disc brake be adjusted. In principle, therefore, it is possible for everyone to keep any part of 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 this is essentially rotationally symmetrical is. As a result, it is advantageous to use the disc brake Form so that the air duct has a sealed ring groove the plate axis is, the vertical, directly under the saucer has opening openings. As a result of the ring groove of the air duct can be at all required points on the disc brake be blown. That will be chosen by a suitable one Positioning of the outlet openings reached.

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.To ensure a controlled drainage under the saucer to reach blown air and at the same time to cause that the cavity of the disc axis is cleaned, the disc brake designed so that the underside of the saucer and the cavity of the plate axis with each other in terms of air flow are connected.

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 so that a Flexible, porous saucer ring from the outlet openings of the air duct is blown with compressed air. As a result, dust will accumulate in the area of this ring avoided. The ring cannot harden. Such a through Dust accumulation caused by hardening of the ring would result cause the saucer to no longer or no longer adequately could dodge if thread thickening or thread knots run through the brake plate. A hardening of the ring would lead to thread breaks. The risk of thread breakage is reduced by the compressed air cleaning of the porous ring avoided.

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 so that on the ring groove radial, outside of that supporting the saucer Blow openings opening between this and the bearing plate connect, the disc brake is not only on the disc axis side cleaned, but also in the area between the plate axis and the surrounding bearing plate. The structural Effort due to the additional blow 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 disc brake is designed so that the air duct in the Bearing plate radial supply air slots for air supply in the Has ring groove. About the number and distribution of the air vents the compressed air supply to the annular groove can Cross-sectional dimensions without significant throttling losses be supplied.

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.To blow the space between the plate axis and To intensify the surrounding bearing plate is the disc brake designed so that the air vents with blow holes are connected, which is outside the supporting the saucer Blow around 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.Another basic way of cleaning the inside the disc brake is given when the air duct in the Bearing plate an annular channel for the compressed air distribution to Blowing the saucer. From such a ring channel from that between the plate axis and the surrounding Blow the existing plate of the disc brake directly on the bearing plate without an annular groove in the plate axis needed. However, the ring channel of the bearing plate is also an advantage 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.To the compressed air supply to the ring groove of the plate axis ensure the plate brake is designed so that the Ring channel of the bearing plate with the ring groove of the plate axis over the supply air slots are connected. There is a structural 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 so that in one horizontal brake carrier intended for further disc brakes an air feed line is arranged, the vertical Connection holes to the ring channels of the bearing plates of the Has disc brakes. It becomes the central compressed air supply achieved a variety of disc brakes, which a common Air supply line is assigned. The arrangement of the Air supply line in the brake carrier allows a constructive simple design of the entire compressed air supply, because the brake carrier in the form of an air feed line without further notice of compressed air lines if it does not is itself designed so that a hollow chamber, the air feed line forms.

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 disc brake is that the air feed line is arranged in parallel Air feed line is associated with the first air feed line connected and / or provided with elastic blowpipes is, each a disc brake of a lower one Blow on the coil level. The further, parallel air feed line improves the compressed air supply to the disc brake if appropriate dimensioned, constant pressure compressed air source or them enables a complete blowing of another disc brake especially 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.Appropriate for a central supply of the air supply To design, the disc brake is designed so that the Air supply line at one end and / or in the area of field surges of the creel is fed.

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 one not shown Coil of a creel in the direction of arrow 11 ' withdrawn with a winding machine, for example with a Warping machine or with a slip machine. The thread 11 passes through the disc brake 10, which it for winding required thread tension issued. The disc brake 10 has an upper plate 14 which is on a lower plate 26 lies on. Both form one with the visible flattenings Plate gap 35 through which the thread 11 in and through the Disc brake 10 is pulled.

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 bowl-shaped pressed parts, the outer shell edges parallel to a central axis 41 point up or down. The plates also have 14.26 inner recesses formed by inner edges parallel to the outer edges 14 ', 26', so that the plates 14, 26 actually are circular.

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 disc brake 10 is with its plates 14,26 on one arranged horizontally extending brake carrier 12, the F-shaped shown in Figure 1 example Cross section. Above this brake carrier 12 or A bearing plate 36 is provided lying directly on this, which carries 39 eyelets 40 with bends, which on Height of the plate gap 35 are arranged and as a result of the illustrated Opposite arrangement the passage area of the thread 11 set by 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 support the plate 14.26. The support is made with a resilient Ring 28, for example a foam ring. Consequently the lower plate 26 can move downwards, if a knot of thread 11 passes through. On the other hand this ring 28 is stiff enough to be required by one Pressure device 20 applied to the upper plate 14 pressure forces to be able to support.

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 direct or indirect are supported on the plate axis 13. For this is the Plate axis 13 assembled with the bearing plate 36, on which Bearing plate of the ring 28 could be supported. That would in a design of the disc brake 10 without a drive Thread cleaning the case. The ring 28 is supported however indirectly via a bearing shaft 25 with which the lower one Plate 26 to be driven via the ring 28. For this the bearing shaft 25 has a shaft end 25 'that the brake carrier 12 interspersed. The bearing shaft 25 is supported however not directly on the brake carrier 12, but in one formed by the bearing plate 36 bearing recess 24, the 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, the ring 28 with an outer circumferential groove 25 '' can accommodate that the ring 28 radially spaced from the adjacent Has 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 is used to drive the bearing shaft 25 Traversing rod 27, the back and forth vertically to the display plane can be moved. The extent of the movement is measured that the lower plate 26 rotates by more than 360 °. Consequently most thread abrasion parts are certain to be stripped without lumps forming in the area of the plates can. Wear on the pair of plates is also prevented. The traversing rod 27 engages with a Rack piece 27 'in the teeth 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 swings back and forth to the same extent, there is a spring 29 which is formed from a piece of wire is. One end of which resiliently clamps in the hollow Bearing shaft 25. The inside diameter of the hollow bearing shaft 25 is dimensioned so large that the radial direction on the brake carrier 12 projecting inner plate rim in the bearing shaft 25 can engage. The other end of the piece of wire engages in the upper plate 14. For example also on the relevant description of EP 0 529 429 A1 pointed out.

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.The upper plate 14 is used to generate a braking force pressed onto the lower plate 26. A pressure device 20 is also described in EP 0 529 429 A1, whereupon hereby Reference is 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 so that they have an air duct 50, with the one or more fiber dust collection points 51 in the area the saucer 26 can be blown. As an an example for such a fiber dust collection point 51 is the cavity 55 to watch. The air duct 50 is continuous in FIGS thin lines that mark the course of the Illustrate air duct 50 below the saucer 26. The arrows of the thin lines symbolize the muzzle points 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 in the area of the plate axis 13 or in the bearing shaft 25, an annular groove 52, which is opposite the Bearing plate 36 is sealed in a manner not shown. The annular groove 52 extends over the circumference of the plate axis 13 evenly distributed axial or vertical outlet openings 53, which is directly on the bottom 54 of the saucer 26 lead to. The air flows in from this underside 54 the cavity 55 of the plate axis 13. If for the air flow Connection of the passage cross section between the inner plate edge of the saucer 26 and the upper end 63 the bearing shaft 25 is not large enough, can be slot-like here Connection openings 64 are provided which are not in shown way evenly over the inner circumference of the bearing shaft 25 are distributed. With the help of those exiting here Compressed air can clean both the underside 54 of the plate 26 are blown, as is 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 flows from the underside 54 of the saucer 26 also in a manner not shown through the porous ring 28 and thus prevents its hardening due to dust accumulation. The dust blown out of the ring 28 enters a space 65 between the bearing shaft 25 and the ring 28 on the one hand and the bearing plate 36 on the other hand. From here on out any dust is blown upwards as shown, whereby there can also be blowing openings 56 which form the annular groove 52 connect to room 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.To keep the inner parts of the brake 10 clean, the Air from the air feed line 60 through the connection bore 66 in the ring channel 59 of the bearing plate 36. From there the air through the one or more air slots 57 into the annular space 52 of the plate axis 13. The annular space 52 is with one or more vertical outlet openings 53 provided. From the outlet openings 53 air flows against the underside 54 of the saucer 26 and is redirected there and flows into the cavity 55 of the plate axis 13 and on the other hand by the porous ring 28 in 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 36 radial supply air slots 57 in the bearing plate. The supply air slots 57 are in turn from an annular channel 59 of the bearing plate 36 supplied. The supply air slots 57 are evenly distributed around the circumference of the bearing plate 36 and may be connected to blow holes 58 from the ring channel 59 with a short way into the room 65 between the bearing plate 36 and ring 28 blow for effective removal to cause existing fiber dust.

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 ring channel 59 of the bearing plate 36 is through a recess formed, which seals against the brake carrier 12 is and via a bore 66 with an air feed line 60 is in fluid communication. The air feed line 60 runs parallel within the brake carrier 12 and is 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.Another air feed line is parallel to the air feed line 60 61 shown with the air feed line 60 can be connected via a bore 67. It is then possible, both air supply lines 60,61 for compressed air supply of the air duct 50 and with accordingly large blowing volume to work. The air feed line 61 can but can also be used to apply a blowpipe 62, which blows onto a disc brake 10 'according to FIG is arranged below the disc brake 10, as shown in FIG. In this case, the air feed lines 60, 61 are as shown not connected.

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 supply lines 60, 61 are fed in in each case at their ends or at one of their ends. But it is also possible to feed in fields. Then every field of a creel supplied separately, for example what then It is an advantage if the coil creel changes field by field he follows. The blowpipes 62 shown can be elastic and consequently hinder working on the Not when winding the bobbin. With field-wise feeding it is understood that the air feed lines 60.61 one Field at a field joint from the air feed lines 60.61 neighboring field must be separated. The feed of compressed air for a creel as a whole depends on the respective needs. The creel can run continuously can be supplied with compressed air, but it can also be in places and / or be supplied discontinuously with compressed air. The choice of the respective compressed air supply is electrical Aids adjustable.

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