Description

Die Erfindung betrifft eine Kettbaumkupplung zur Verbindung eines Kettbaumes mit Kettbaumrohr mit einer Webmaschine, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a warp beam coupling for connecting a warp beam with Warp beam tube with a weaving machine, according to the preamble of claim 1.

Die Kettbaumkupplung hat die Aufgabe, den Kettbaumantrieb mit dem Kettbaum bzw. Kettbaumrohr lösbar zu verbinden und die Kraftübertragung vom Antrieb auf das Kettbaumrohr sicherzustellen.
In bekannter Art besteht die Kettbaumkupplung z.B. aus einer an einem Ende des Kettbaumrohres angeflanschten Welle, welche ein Kettbaumzahnrad trägt, welches wiederum mit dem Antriebsritzel eines Antriebsmotors kämmt. Diese Art der Kupplung hat den Vorteil, daß eine hoch belastbare und spielfreie Kraftübertragung vom Antrieb auf das Kettbaumrohr erzielt wird. Nachteilig ist, daß beim Austausch des Kettbaumes die, meist durch Schrauben gesichert, Flanschverbindung zwischen Kettbaumrohr und Antriebswelle gelöst werden muß, was einen relativ hohen Zeitaufwand erfordert und ein fehlerhaftes Anziehen der Schrauben beim Wiederankuppeln nicht ausschließt.The warp beam coupling has the task of releasably connecting the warp beam drive to the warp beam or warp beam tube and ensuring the transmission of power from the drive to the warp beam tube.
In a known manner, the warp beam coupling consists, for example, of a shaft flanged to one end of the warp beam tube which carries a warp beam gear which in turn meshes with the drive pinion of a drive motor. This type of coupling has the advantage that a highly resilient and play-free power transmission from the drive to the warp beam tube is achieved. The disadvantage is that when replacing the warp beam, the flange connection between the warp beam tube and the drive shaft, which is usually secured by screws, must be released, which takes a relatively long time and does not preclude incorrect tightening of the screws when recoupling.

Man hat daraufhin die sogenannte "EURO"-Kupplung entwickelt, welche eine Kuppelwelle aufweist, die im Querschnitt als Mehrkant ausgebildet ist und mit einer zugeordneten Aufnahme an der Stirnseite des Kettbaumrohres in Eingriff gebracht werden kann.
Vorteil hierbei ist, daß zum Lösen der Verbindung meist nur eine Sicherungsschraube gelöst werden muß und die Kupplungswelle danach einfach aus der Aufnahme im Kettbaumrohr gezogen werden kann. Nachteile sind die eingeschränkte Belastbarkeit der Mehrkantwelle, sowie ein verhältnismäßig großes Spiel zwischen Welle und Wellenaufnahme, welches sich einerseits in Unregelmäßigkeiten der Webware niederschlägt und andererseits zu einem frühzeitigen Verschleiß der Kupplungsteile führt.The so-called "EURO" coupling was then developed, which has a coupling shaft which is designed as a polygon in cross section and can be brought into engagement with an associated receptacle on the end face of the warp beam tube.
The advantage here is that usually only one locking screw has to be loosened to release the connection and the coupling shaft can then simply be pulled out of the receptacle in the warp beam tube. Disadvantages are the limited load capacity of the polygonal shaft, as well as a relatively large amount of play between the shaft and the shaft holder, which is reflected in irregularities in the woven fabric on the one hand and leads to premature wear of the coupling parts on the other.

Ferner ist aus der EP 0 451 895 A eine Kettbaumkupplung gemäß dem Oberbergriff des unablangigen Anspruchs bekannt.Furthermore, a warp beam coupling according to EP 0 451 895 A is the overcame of the independent claim known.

Der Erfindung liegt die Aufgabe zugrunde, eine Kettbaumkupplung für die Antriebsverbindung zwischen Kettbaumrohr und Kettbaumantrieb derart weiterzubilden, daß einerseits eine möglichst hoch belastbare und spielfreie Kraftübertragung erzielt wird und andererseits ein schnelles Lösen und Wiederherstellen der Antriebsverbindung zwischen Kettbaumantrieb und Kettbaum möglich ist.The invention is based, a warp beam coupling for the task Develop drive connection between warp beam tube and warp beam drive such that on the one hand, the highest possible load-bearing and play-free power transmission is achieved and on the other hand a quick loosening and restoring the drive connection between Warp beam drive and warp beam is possible.

Die Lösung der Aufgabe erfolgt erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1.The object is achieved according to the invention by the characterizing features of Claim 1.

Wesentliches Merkmal der Erfindung ist, daß die Kraftübertragung vom Kettbaumantrieb auf das Kettbaumrohr des Kettbaumes mittels jeweils eines Kupplungsflansches erfolgt, welche Kupplungsflansche mit einer Stirnverzahnung (Hirth-Verzahnung) versehen sind, die eine formschlüssige Verbindung der Kupplungsflansche sicherstellen.An essential feature of the invention is that the power transmission from the warp beam drive to the Warp beam tube of the warp beam by means of a coupling flange, which Coupling flanges are provided with spur gearing (Hirth serration), one Ensure positive connection of the coupling flanges.

Die Kupplungsflansche werden durch geeignete Mittel miteinander verspannt.The coupling flanges are clamped together by suitable means.

Dabei ist gemäß einer ersten Ausführungsform vorgesehen, daß das Einkuppeln und Auskuppeln manuell erfolgt, wobei die beiden Kupplungsflansche mittels einer einzigen Spannschraube gegen Auskuppeln miteinander verspannt sind.It is provided according to a first embodiment that the coupling and uncoupling is done manually, with the two coupling flanges using a single clamping screw Disengaging are clamped together.

In einer weiteren Ausführung ist vorgesehen, daß das Einkuppeln und Auskuppeln automatisch, z.B. mit Hilfe von Pneumatik-bzw. Hydraulikeinrichtungen, erfolgt, wobei die Kupplungsflansche durch hydraulisch oder pneumatisch betätigte Mittel zusammengeführt und mechanisch miteinander verspannt werden.In a further embodiment it is provided that the engaging and disengaging automatically, e.g. with the help of pneumatic or Hydraulic devices, takes place, the coupling flanges brought together hydraulically or pneumatically and mechanically be braced together.

Erfindungsgemäß ergeben sich folgende Vorteile:

  • Das Kuppeln und Verspannen erfolgt nach einem weitgehend vorgegebenen Ablauf manuell bzw. automatisch, so daß Bedienungsfehler, die ein unsauberes Kuppeln zur Folge haben, weitgehend vermieden werden können.
  • Durch die stimverzahnten Kupplungsflansche ergibt sich eine spielfreie Verbindung zwischen Kettbaum und Kettbaumantrieb, wobei durch die Hirth-Verzahnung eine automatische Zentrierung, d.h. axiale Ausrichtung, des Kettbaumes gegenüber dem Kettbaumantrieb erfolgt. Die Stirnverzahnung ermöglicht ein sehr hohes zu übertragendes Drehmoment, welches beim Stand der Technik nur durch die bekannte, geschraubte Flanschverbindung erreicht wird.
  • Nach dem Kuppeln und Verspannen wirken keine axialen Kräfte auf den Kettbaum. Die statischen Lager des Kettbaumes werden geschont.
The following advantages result according to the invention:
  • Coupling and bracing is carried out manually or automatically according to a largely predetermined sequence, so that operating errors which result in improper coupling can be largely avoided.
  • Due to the spline coupling flanges, there is a play-free connection between the warp beam and the warp beam drive, with the Hirth serration providing automatic centering, ie axial alignment, of the warp beam with respect to the warp beam drive. The spur toothing enables a very high torque to be transmitted, which in the prior art can only be achieved by the known screwed flange connection.
  • After coupling and tensioning, no axial forces act on the warp beam. The static bearings of the warp beam are protected.

In einer ersten Ausführungsform gemäß Figur 1 ist eine manuell betätigte Kettbaumkupplung dargestellt.In a first embodiment according to Figure 1 is a manually operated warp beam coupling shown.

Man erkennt das Kettbaumrohr 1, an welchem stirnseitig, z.B. mittels Schraubbolzen 1a, ein Kupplungsflansch 2 befestigt ist. Der Kupplungsflansch 2 ist mit einer umlaufenden Stirnverzahnung 3 (auch bezeichnet als Hirth-Stirnverzahnung) versehen, wobei die Zähne bezüglich der Rotationsachse 12a radial verlaufen.One recognizes the warp beam tube 1, on the front side, e.g. by means of screw bolts 1a, a Coupling flange 2 is attached. The coupling flange 2 is circumferential Front toothing 3 (also referred to as Hirth toothing) provided, the teeth run radially with respect to the axis of rotation 12a.

Der Kupplungsflansch 2 besitzt eine Mittelbohrung 4, welche eine umlaufende Stufe 5 mit einer Schräge 5a ausbildet, siehe auch Figur2. In die Mittelbohrung 4 ist ein Spannstück 6 eingesetzt, welches sich mit einer umlaufenden Flanke 7 an die Schräge 5a der Stufe 5 anlegt und im Kupplungsflansch 2 zentriert gehalten ist.The coupling flange 2 has a central bore 4, which has a circumferential step 5 with a Forms slope 5a, see also Figure 2. A clamping piece 6 is inserted into the central bore 4, which engages with a circumferential edge 7 on the slope 5a of level 5 and in Coupling flange 2 is kept centered.

Die Kettbaumkupplung selbst besteht aus einer in axialer Richtung 20 bzw. 20' beweglichen Lagerglocke 12, die in einem Kettbaumlager 14 gelagert ist. Die Lagerung erfolgt mittels am Kettbaumlager 14 befestigten Lagerringen 15,16 und zugeordneten Lagerschalen 15a,16a. Durch Betätigen eines Hebels 19 kann die Lagerglocke 12 in axialer Richtung 20 bzw. 20' gegenüber dem stationären Kettbaumlager 14 verschoben werden. Der Hebel 19 wird in einer Öffnung des Kettbaumlagers 14 bzw. eines Lagerrings 15 gehalten und stützt sich dort ab. Bei Betrieb der Webmaschine kann der Hebel 19 ganz aus seinem Sitz entnommen werden.The warp beam coupling itself consists of a movable in the axial direction 20 or 20 ' Bearing bell 12, which is mounted in a warp beam 14. The storage takes place by means of Warp beam bearings 14 fastened bearing rings 15, 16 and associated bearing shells 15a, 16a. By Operating a lever 19 can opposite the bearing bell 12 in the axial direction 20 or 20 ' the stationary warp beam warehouse 14 are moved. The lever 19 is in an opening of the Warp beam bearing 14 or a bearing ring 15 held and is supported there. When operating the The loom 19 can be completely removed from its seat.

An der Lagerglocke 12 ist ein Antriebszahnrad 11 befestigt, welches mit einem entsprechenden Antriebsritzel (nicht dargestellt) eines Antriebsmotors (nicht dargestellt) kämmt.On the bearing bell 12, a drive gear 11 is attached, which with a corresponding Drive pinion (not shown) of a drive motor (not shown) meshes.

An der dem Kettbaumrohr 1 zugewandten Stirnseite der Lagerglocke 12 ist ein weiterer Kupplungsflansch 8 befestigt, welcher ebenfalls mit einer umlaufenen Stirnverzahnung 9 versehen ist, die der Stirnverzahnung 3 des kettbaumseitigen Kupplungsflansches 2 entspricht.There is another on the end face of the bearing bell 12 facing the warp beam tube 1 Coupled flange 8 attached, which is also provided with a circumferential spline 9 is, which corresponds to the spur toothing 3 of the warp beam side coupling flange 2.

Um und entlang der Rotationsachse 12a der Lagerglocke 12 ist ein Führungsrohr 18 angeordnet, welches eine Spannschraube 17 aufnimmt, die ausgehend vom Boden 12b der Lagerglocke 12 in eine im Verbindungsstück 6 mittig angeordnete Gewindebohrung 6a einschraubbar ist.A guide tube 18 is arranged around and along the axis of rotation 12a of the bearing bell 12, which receives a clamping screw 17 which, starting from the bottom 12b of the bearing bell 12 in a threaded hole 6a arranged centrally in the connecting piece 6 can be screwed in.

Funktionsweise:Functionality:

Oberhalb der Rotationsachse 12a gemäß Figur 1 ist die Kettbaumkupplung in nicht gekuppeltem Zustand dargestellt, d.h. die entsprechenden Stirnverzahnungen 3 und 9 der Kupplungsflansche 2 und 8 sind nicht in Eingriff miteinander. Die Lagerglocke 12 befindet sich gegenüber dem feststehenden Kettbaumlager 14 in ihrer hintersten Stellung (in Richtung 20'). Der Kettbaum bzw. das Kettbaumrohr 1 liegt auf einer sogenannten Lünette der Webmaschine (nicht dargestellt) auf und wird durch diese vorpositioniert und gestützt.Above the axis of rotation 12a according to FIG. 1, the warp beam coupling is not coupled State shown, i.e. the corresponding spur gears 3 and 9 of the coupling flanges 2 and 8 are not in engagement with each other. The bearing bell 12 is opposite fixed warp beam bearing 14 in its rearmost position (in the direction 20 '). The warp beam or the warp beam tube 1 rests on a so-called bezel of the weaving machine (not shown) and is prepositioned and supported by it.

Um nun das Kettbaumrohr 1 mit dem Antrieb zu koppeln, wird zunächst der Hebel 19 in Pfeilrichtung 20' betätigt, so daß sich die Lagerglocke 12 mitsamt dem Antriebszahnrad 11 und dem Kupplungsflansch 8 in axialer Richtung 20 auf den kettbaumseitigen Kupplungsflansch 2 zubewegt, wie es in der unteren Hälfte von Figur 1 dargestellt ist. Die Koppelung muß natürlich bei Stillstand der Maschine erfolgen.In order to couple the warp beam tube 1 to the drive, the lever 19 is first in Arrow direction 20 'actuated so that the bearing bell 12 together with the drive gear 11 and the coupling flange 8 in the axial direction 20 on the warp beam side coupling flange 2 moved, as shown in the lower half of Figure 1. The coupling must of course when the machine is at a standstill.

Die Verschiebebewegung wird nun durch weiteres Betätigen des Hebels fortgesetzt, bis die Stirnverzahnung 9 des Kupplungsflansches 8 mit der Stirnverzahnung 3 des kettbaumseitigen Kupplungsflansches 2 in formschlüssigen Eingriff gelangt. Dabei kann das Ineinandergreifen der Verzahnungen 3, 9 durch leichtes Drehen der Lagerglocke 12 bzw. des mit der Lagerglocke 12 verbundenen Kupplungsflansches 8 unterstützt werden.The shifting movement is now continued by operating the lever until the Front toothing 9 of the coupling flange 8 with the front toothing 3 of the warp beam side Coupling flange 2 comes into positive engagement. The meshing of the Gears 3, 9 by turning the bearing bell 12 or the bearing bell 12 slightly connected coupling flange 8 are supported.

Sind die Verzahnungen 3, 9 der Kupplungsflansche 2, 8 in Eingriff miteinander, wird die Spannschraube 17 durch den Boden 12b der Lagerglocke 12 und durch das Führungsrohr 18 hindurchgesteckt und in der zugeordneten Gewindebohrung 6a des Spannstücks 6 mit einem definierten Anzugsmoment angezogen. Dadurch wird sowohl ein Formschluß als auch ein Kraftschluß zwischen den beiden Kupplungsflanschen 2 und 8 erzielt. Es entsteht ein spielfreie Verbindung zwischen dem Kettbaumrohr 1 des Kettbaumes und dem Kettbaumantrieb.Are the teeth 3, 9 of the coupling flanges 2, 8 in engagement with each other, the Tension screw 17 through the bottom 12b of the bearing bell 12 and through the guide tube 18th inserted through and in the associated threaded bore 6a of the clamping piece 6 with a defined tightening torque. As a result, both a form fit and a Non-positive connection between the two coupling flanges 2 and 8 achieved. There is a backlash-free Connection between the warp beam tube 1 of the warp beam and the warp beam drive.

Wichtig ist, daß nach dem Verbinden der Kupplungsflansche 2 und 8 keine axialen Kräfte auf den Kettbaum wirken, und der Kettbaum nun kupplungsseitig ausschließlich im Kettbaumlager 14 gelagert ist, d.h. nicht mehr auf der Lünette aufliegt. Durch die Hirth-Stirnverzahnung erfolgt außerdem in vorteilhafter Weise eine automatische Zentrierung des Kettbaumrohres 1 gegenüber dem Kettbaumlager 14.It is important that after connecting the coupling flanges 2 and 8 no axial forces on the Warp beam act, and the warp beam now only on the coupling side in warp beam bearing 14 is stored, i.e. no longer rests on the bezel. Thanks to the Hirth serration also advantageously compared to an automatic centering of the warp beam tube 1 the warp beam bearing 14.

In den Figuren 2 und 3 ist der kettbaumseitige Kupplungsflansch 2 dargestellt. Man erkennt die abgestufte Mittelbohrung 4, in welche das Spannstück 6 gemäß Figur 1 eingesetzt ist, und die umlaufende radiale Stimverzahnung 3. Die Stirnverzahnung 3 kann sowohl, wie dargestellt, geradlinig radial als auch schräg radial ausgeführt sein.In Figures 2 and 3, the warp beam side coupling flange 2 is shown. You can see that stepped center bore 4, in which the clamping piece 6 is inserted according to Figure 1, and circumferential radial splines 3. The splines 3 can, as shown, be straight radial as well as obliquely radial.

Die Figuren 4 und 5 zeigen eine zweite Ausführungsform der Kupplungsvorrichtung, bei der die Koppelung automatisch erfolgen kann.Figures 4 and 5 show a second embodiment of the coupling device, in which the Coupling can be done automatically.

Mit Bezug auf Figur 1 sind gleiche Teile mit gleichen Bezugsziffern bezeichnet.With reference to Figure 1, the same parts are denoted by the same reference numerals.

Ein wesentlicher Unterschied zur ersten Ausführungsform ist, daß kein Spannstück 6 zum Verspannen der Kupplungsflansche 2,8 benötigt wird.An essential difference from the first embodiment is that no clamping piece 6 for Clamping the coupling flanges 2.8 is required.

Die Lagerglocke 12' ist als beidseitig offenes, rotationssymmetrisches Teil ausgebildet, und wiederum im Kettbaumlager 14 gelagert.The bearing bell 12 'is designed as a rotationally symmetrical part which is open on both sides, and again stored in warp beam warehouse 14.

Der Lagerring 15 umfaßt einen Grundflansch 21, in welchem ein Ende eines Pneumatikzylinders 22 aufgenommen ist. Das andere Ende des Pneumatikzylinders 22 ist durch einen Zylinderdeckel 24 geschlossen. Zylinderdeckel 24, Zylinder 22 und Grundflansch 21 sind mittels Schrauben 14a fest mit dem Kettbaumlager 14 verbunden.The bearing ring 15 comprises a base flange 21 in which one end of a pneumatic cylinder 22 is included. The other end of the pneumatic cylinder 22 is through a cylinder cover 24 closed. Cylinder cover 24, cylinder 22 and base flange 21 are by means of screws 14a firmly connected to the warp beam bearing 14.

Im Pneumatikzylinder 22 ist ein Hohlkolben 26 beweglich aufgenommen, welcher sich an der Innenwand des Pneumatikzylinders 22 und, mittels eines rohrförmigen Ansatzes 26a, am Innenumfang des Zylinderdeckels 24 abstützt. Am Grundflansch 21 bzw. am Zylinderdeckel 24 ist jeweils ein Druckluftanschluß 23 bzw. 25 vorgesehen, so daß der Hohlkolben 26 in beiden Richtungen 20 bzw. 20' arbeiten kann.In the pneumatic cylinder 22, a hollow piston 26 is movably received, which is located on the Inner wall of the pneumatic cylinder 22 and, by means of a tubular extension 26a, on Supported inner circumference of the cylinder cover 24. On the base flange 21 or on the cylinder cover 24 a compressed air connection 23 and 25 is provided, so that the hollow piston 26 in both Directions 20 or 20 'can work.

Im Boden des Hohlkolbens 26 befindet sich eine mit Druckmittel beaufschlagbare Schnellkupplung 27, die mit dem Kolben 26 in Verbindung steht.In the bottom of the hollow piston 26 there is a pressurizable medium Quick coupling 27, which is connected to the piston 26.

Innerhalb des Hohlkolbens 26, welcher z.B. als pneumatisch oder hydraulisch beaufschlagbarer Arbeitszylinder ausgebildet ist, ist ein mit Druckmittel beaufschlagbarer Kolben 28 verschiebbar angeordnet, der eine sich in axialer Richtung 20 erstreckende Kolbenstange 29 trägt. Die Kolbenstange 29 läuft innerhalb einer Verbindungsbüchse 31, welche wiederum am Hohlkolben 26 befestigt ist und in axialer Richtung 20, 20' verschieblich innerhalb der Lagerglocke 12' angeordnet ist. Innerhalb der Verbindungsbüchse 31 ist ein die Kolbenstange 29 umgebendes Federpaket 32 angeordnet, welches sich einerseits an einer stimseitigen Ringfläche 31a der Verbindungsbüchse 31 und andererseits am Boden 28a des Kolbens 28 abstützt.Inside the hollow piston 26, which e.g. as pneumatically or hydraulically actuated Working cylinder is formed, a piston 28 can be acted upon by pressure medium arranged, which carries a piston rod 29 extending in the axial direction 20. The Piston rod 29 runs within a connecting sleeve 31, which in turn on the hollow piston 26 is fastened and displaceable in the axial direction 20, 20 'within the bearing bell 12' is arranged. Inside the connecting sleeve 31 is a piston rod 29 surrounding Spring assembly 32 arranged, which is on the one hand on an end-side annular surface 31a Connection sleeve 31 and on the other hand supported on the bottom 28a of the piston 28.

An der Stirnseite der Verbindungsbüchse 31 ist in einer zugeordneten Öffnung eine Haltebüchse 33 für einen Klauenträger 34 angeordnet, am besten zu sehen in Figur 5, welcher durch eine in der Haltebüchse angeordnete Feder 35, z.B. eine oder mehrere Tellerfedern, vorgespannt ist. Der Klauenträger 34 umfaßt mehrere radial angeordnete und sich in axialer Richtung 20 erstreckende Klauen 36, welche schwenkbar um eine Achse 37 am Klauenträger 34 angeordnet sind.On the end face of the connecting sleeve 31 there is a holding sleeve in an associated opening 33 arranged for a claw carrier 34, best seen in Figure 5, which by a in the spring 35 arranged e.g. one or more disc springs is preloaded. The Claw carrier 34 comprises a plurality of radially arranged and extending in the axial direction 20 Claws 36 which are arranged pivotably about an axis 37 on the claw carrier 34.

Durch eine Ringfeder 38 werden die Klauen 36 in ihrer funktionslosen Stellung vorgespannt. Die Klauen 36 sind in radialer Richtung 40 nach außen beweglich und werden durch Abgleiten an der am freien Ende der Kolbenstange 29 vorhandenen Steuerkante 30 betätigt.The claws 36 are pretensioned in their non-functional position by an annular spring 38. The Claws 36 are movable in the radial direction 40 to the outside and are slid on the at the free end of the piston rod 29 existing control edge 30 actuated.

Die freien Enden der Klauen 36 weisen jeweils eine Art Rastnase 36a auf, die dazu vorgesehen ist, sich an die in der Mittelbohrung 4 des kettbaumseitigen Kupplungsflansches 2 vorhandene Schräge 5a der umlaufenden Stufe 5 anzulegen, wobei der Sitz der Klauen 36 durch die Kolbenstange 29 gesichert wird.The free ends of the claws 36 each have a type of locking lug 36a, which is provided for this purpose is, the existing in the center hole 4 of the warp beam side coupling flange 2 Apply slope 5a of the circumferential step 5, the seat of the claws 36 by the Piston rod 29 is secured.

Funktionsweise:Functionality:

Oberhalb der Rotationsachse 12a gemäß Figur 4 ist die Kettbaumkupplung in nicht gekuppeltem Zustand dargestellt. Dabei befindet sich der Hohlkolben 26 in seiner hintersten Stellung (Pfeilrichtung 20'); am Druckluftanschluß 23 liegt Druck an, während der Druckluftanschluß 25 drucklos ist.
Unterhalb der Rotationsachse 12a befindet sich der Kolben 28 in seiner vordersten Stellung (Pfeilrichtung 20); am Anschluß 25 liegt Druck an, wobei die mit dem Kolben 28 verbundene Kolbenstange 29 entgegen der Kraft des Federpaketes 32 nach vorne (Pfeilrichtung 20) gedrückt wird, so daß die Klauen 36 zunächst durch die Kraft der Feder 35 in ihrer funktionslosen Stellung gehalten sind.The warp beam coupling is shown in the uncoupled state above the axis of rotation 12a according to FIG. The hollow piston 26 is in its rearmost position (arrow direction 20 '); pressure is present at the compressed air connection 23, while the compressed air connection 25 is depressurized.
The piston 28 is in its foremost position (arrow direction 20) below the axis of rotation 12a; pressure is present at the connection 25, the piston rod 29 connected to the piston 28 being pressed forward against the force of the spring assembly 32 (arrow direction 20), so that the claws 36 are initially held in their non-functional position by the force of the spring 35.

Wird also der Druckluftanschluß 23 drucklos und gleichzeitig der Druckluftanschluß 25 beaufschlagt, so bewirkt das ein axiales Verschieben des Hohlkolbens 26 relativ zum Kettbaumlager 14 hin. Demzufolge werden die am oder im Hohlkolben 26 befindlichen Bauteile, nämlich die Verbindungsbüchse 31, der Kolben 28 mit Kolbenstange 29, das Federpaket 32, der Klauenträger 34 mit Klauen 36, in Pfeilrichtung 20 verschoben. Bei Beaufschlagung des Hohlkolbens 26 verschiebt sich die Verbindungsbüchse 31 so weit, bis sie an einem inneren Anschlag 10 des Kupplungsflansches 8 mit ihrer stirnseitigen Ringfläche 31b anstößt und dabei den Kupplungsflansch 8 in Pfeilrichtung 20 des kettbaumseitigen Kupplungsflansches 2 drückt, so daß die Stirnverzahnungen 3 und 9 der Kupplungsflansche 2 und 8 in gegenseitigen formschlüssigen Eingriff gebracht werden.
Figur 5 zeigt die Position der Klauen 36 bevor diese formschlüssig mit dem Kupplungsflansch 2 in Verbindung gebracht werden.If the compressed air connection 23 is depressurized and at the same time the compressed air connection 25 is acted upon, this causes an axial displacement of the hollow piston 26 relative to the warp beam bearing 14. As a result, the components located on or in the hollow piston 26, namely the connecting sleeve 31, the piston 28 with the piston rod 29, the spring assembly 32, the claw carrier 34 with claws 36, are displaced in the direction of the arrow 20. When the hollow piston 26 is acted upon, the connecting sleeve 31 moves until it abuts an inner stop 10 of the coupling flange 8 with its end-face annular surface 31b and thereby presses the coupling flange 8 in the direction of arrow 20 of the warp beam-side coupling flange 2, so that the spur gears 3 and 9 the coupling flanges 2 and 8 are brought into mutual positive engagement.
FIG. 5 shows the position of the claws 36 before they are positively connected to the coupling flange 2.

Die Kupplungsflansche 2 und 8 liegen aneinander, wobei die Klauen 36 sich noch in ihrer radial innersten Position (funktionslosen Position) befinden.The coupling flanges 2 and 8 lie against each other, the claws 36 still being radial innermost position (non-functional position).

Wird die Druckmittelversorgung deaktiviert, d.h. der Kolben 28 wird druckentlastet, werden der Kolben 28 und die Kolbenstange 29 durch die Kraft des Federpaketes 32 in Pfeilrichtung 20' gedrückt. Während der Rückwärtsbewegung der Kolbenstange 29 gleiten die Klauen 36 entlang deren Steuerkante 30. Dadurch werden die Klauen 36 in Pfeilrichtung 40 gedrückt und stellen an der Stufe 5 des kettbaumseitigen Kupplungsflansches 2 einen Formschluß her. Die formschlüssige Position der Klauen 36 wird dabei durch das auf die Klauen 36 wirkende geometrisch ausgebildete freie Ende 29a der Kolbenstange 29 gesichert.If the pressure medium supply is deactivated, i.e. the piston 28 is relieved of pressure, the Piston 28 and the piston rod 29 by the force of the spring assembly 32 in the direction of the arrow 20 ' pressed. The claws 36 slide along during the backward movement of the piston rod 29 whose control edge 30. As a result, the claws 36 are pressed in the direction of arrow 40 and start the stage 5 of the warp beam side coupling flange 2 a positive connection. The the positive position of the claws 36 is determined by that acting on the claws 36 Geometrically designed free end 29a of the piston rod 29 secured.

Die beiden Kupplungsflansche 2,8 sind also gegen ein Voneinanderlösen gesichert.
In der unteren Hälfte von Figur 4, also unterhalb der Rotationsachse 12a, wird die Spannkraft auf die Kolbenstange 29 zur Verriegelung der Klauen 36 allein durch das Federpaket 32 aufgebracht.The two coupling flanges 2.8 are thus secured against being released from one another.
In the lower half of FIG. 4, that is to say below the axis of rotation 12a, the clamping force is applied to the piston rod 29 for locking the claws 36 solely by the spring assembly 32.

Der Kraftverlauf in den einzelnen Teilen ist durch die gestrichelte Linie 41 dargestellt. Wichtig ist, daß auf die Lagerung der Klauen 36 keine wesentliche Kraft wirkt, sondern nur das freie äußere Ende der Klauen zur Kraftübertragung dient. Mögliche geringe axiale Kräfte auf die Klauen 36 werden durch die federnde Lagerung des Klauenträgers 34 aufgenommen.The force curve in the individual parts is shown by the dashed line 41. Important is that no significant force acts on the claws 36, but only the free force outer end of the claws is used for power transmission. Possible low axial forces on the Claws 36 are received by the resilient mounting of the claw carrier 34.

Das Lösen der Verriegelung und das Entkoppeln des Kettbaumes von der Webmaschine erfolgt in umgekehrter Reihenfolge zu der vorstehend beschriebenen Reihenfolge.The lock is released and the warp beam is uncoupled from the weaving machine in reverse order to the order described above.

Danach werden die Klauen 36 von ihrem Sitz gelöst, indem der Kolben 28 beaufschlagt wird, welcher die Kolbenstange 29 in Pfeilrichtung 20 bewegt, so daß die Klauen 36 die Steuerkante 30 entlanggleiten und durch die Kraft der Ringfeder 38 entgegen der Pfeilrichtung 40 geschwenkt werden.Thereafter, the claws 36 are released from their seat by actuating the piston 28, which moves the piston rod 29 in the direction of arrow 20, so that the claws 36 the control edge 30 slide along and pivoted against the direction of arrow 40 by the force of the ring spring 38 become.

Nachdem die Klauen 36 gelöst sind, wird die Pneumatik betätigt, d.h. Druckluft am Druckluftanschluß 23 angelegt, so daß sich die Verbindungshülse 31 in Pfeilrichtung 20' bewegt und dabei an einem inneren Anschlag 13 der Lagerglocke 12' anstößt, siehe auch Figur 4. Dadurch wird die Lagerglocke 12' in Pfeilrichtung 20' mitgenommen, so daß sich der Kupplungsflansch 8 vom kettbaumseitigen Kupplungsflansch 2 löst.After the claws 36 are released, the pneumatics are actuated, i.e. Compressed air on Compressed air connection 23 is applied so that the connecting sleeve 31 moves in the direction of the arrow 20 ' and thereby abuts an inner stop 13 of the bearing bell 12 ', see also FIG. 4. As a result, the bearing bell 12 'is taken along in the direction of the arrow 20', so that the Coupling flange 8 detaches from the coupling flange 2 on the warp beam side.

Es ist noch zu erwähnen, daß der Kolben 26 gegenüber dem Zylinder 22 durch sowohl radial als auch axial wirkende Dichtungspakete 39 abgedichtet ist.It should also be mentioned that the piston 26 relative to the cylinder 22 by both radial and also axially acting seal packs 39 is sealed.

Figur 6 zeigt eine Darstellung der Einzelteile der Haltebüchse 33 mit den darin angeordneten Klauenträger 34 mit Klauen 36. Die gesamte Anordnung ist in einer von der Ringfläche 31b umschlossenen Aufnahme in der Verbindungsbüchse 31 getragen. Vorzugsweise ist die Haltebüchse 33 über ein Gewinde mit der Verbindungsbüchse 31 verbunden. Figure 6 shows an illustration of the individual parts of the holding sleeve 33 with the arranged therein Claw carrier 34 with claws 36. The entire arrangement is in one of the annular surface 31b enclosed receptacle in the connecting sleeve 31 worn. Preferably, the Retaining bush 33 is connected to the connecting bush 31 via a thread.
