The torque generator is linked to the creel through a reduction gear stage (20,22). To control a creel, the torque generator has a coil spring (28). The gear stage can be a belt gearing. The torque generator is connected to the drive shaft of the drive. An additional gear stage (30,32) is between the drive and the torque generator.

Description

Die Erfindung betrifft eine Vorrichtung zum Steuern eines Spulenrahmens einer Textilmaschine, der mittels einer Schwenkwelle begrenzt drehbar gelagert und mit einem Drehmomenterzeuger belastbar ist, der gesteuert durch ein Antriebselement definierte Drehmomente erzeugt.The invention relates to a device for controlling a Coil frame of a textile machine, which by means of a Swivel shaft with limited rotation and with one Torque generator is resilient, which is controlled by a Drive element generates defined torques.

Eine gattungsgemäße Vorrichtung zum Steuern eines Spulenrahmens einer Textilmaschine ist beispielsweise in der DE 198 17 363 A1 beschrieben.
Bei dieser bekannten Vorrichtung wird eine in einem Spulenrahmen gehaltene Spule von einer Walze mittels Reibungskraft angetrieben. Zwischen der antreibenden Walze und der Spule soll dabei ein exakt vorgegebener Spulenauflagedruck realisiert werden, der steuerbar ist, um beispielsweise einen definierten Schlupf zwischen Spule und Walze einstellen zu können.
Der Spulenrahmen ist daher mittels einer Schwenkwelle begrenzt drehbar gelagert, wobei eine Anschlussscheibe drehfest mit der Schwenkwelle verbunden ist.
Die Anschlussscheibe ist außerdem über Schraubenfedern mit einem Getriebezahnrad dergestalt verbunden, dass eine Drehung des Getriebezahnrads mittels eines Antriebsmotors, insbesondere eines Schrittmotors, ein auf die Anschlussscheibe und damit auf die Schwenkwelle wirkendes Drehmoment erzeugt. Um auf die Schwenkwelle ein ausreichend großes Drehmoment einleiten zu können, sind zwischen dem Getriebezahnrad und der Anschlussscheibe insgesamt sechs tangential zur Schwenkwelle angeordnete Schraubenfedern vorgesehen.A generic device for controlling a coil frame of a textile machine is described for example in DE 198 17 363 A1.
In this known device, a coil held in a coil frame is driven by a roller by means of frictional force. Between the driving roller and the spool, a precisely specified spool contact pressure is to be realized, which can be controlled, for example, to be able to set a defined slip between the spool and roller.
The coil frame is therefore rotatably supported to a limited extent by means of a swivel shaft, a connecting disk being connected in a rotationally fixed manner to the swivel shaft.
The connecting disk is also connected to a gear wheel via helical springs in such a way that rotation of the gear wheel by means of a drive motor, in particular a stepper motor, generates a torque acting on the connecting disk and thus on the swivel shaft. In order to be able to apply a sufficiently large torque to the swivel shaft, a total of six coil springs arranged tangentially to the swivel shaft are provided between the gear wheel and the connecting disk.

Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine Vorrichtung zum definierten Steuern eines Spulenrahmens zu schaffen, die besonders effektiv und gleichzeitig kostengünstig und einfach im Aufbau ist.Starting from the aforementioned prior art, the Invention, the object of a device for defined taxes to create a coil frame that particularly effective and at the same time inexpensive and simple is under construction.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Drehmomenterzeuger mittels einer Untersetzungsgetriebestufe mit dem Spulenrahmen verbunden ist.
Das heißt, durch das Einschalten einer Untersetzungsgetriebestufe kann der Drehmomenterzeuger relativ schwach ausgelegt und einfach gestaltet sein.
Die für ein definiertes Steuern des Spulenrahmens an der Schwenkachse erforderlichen hohe Drehmomente werden dennoch zuverlässig bereitgestellt.This object is achieved according to the invention in that the torque generator is connected to the coil frame by means of a reduction gear stage.
That is, by turning on a reduction gear stage, the torque generator can be designed to be relatively weak and simple.
The high torques required for a defined control of the coil frame on the swivel axis are nevertheless reliably provided.

Wie im Anspruch 2 dargelegt, weist der Drehmomenterzeuger vorteilhafterweise eine Spiralfeder auf.
Durch den Einsatz einer Spiralfeder lässt sich ein sehr einfacher, kostengünstiger Aufbau der gesamten Vorrichtung erreichen. Hierzu ist die Spiralfeder einerseits an einem ersten Element des Drehmomenterzeugers befestigt, das von dem Antriebselement verstellt wird. Andererseits ist die Spiralfeder mit einem zweiten Element verbunden, das mit dem Getriebe gekoppelt ist. Durch Verdrehen des ersten Elementes gegenüber dem zweiten Element erzeugt die Spiralfeder eine definierte Kraft, die in weiten Bereichen eingestellt werden kann, da die Spiralfeder aufgrund ihrer Bauart um einen großen Winkel verdreht werden kann, und die in ein Drehmoment umgesetzt wird. As set out in claim 2, the torque generator advantageously has a coil spring.
By using a spiral spring, a very simple, inexpensive construction of the entire device can be achieved. For this purpose, the spiral spring is attached on the one hand to a first element of the torque generator which is adjusted by the drive element. On the other hand, the coil spring is connected to a second element which is coupled to the transmission. By turning the first element in relation to the second element, the spiral spring generates a defined force which can be adjusted over a wide range because the spiral spring can be rotated through a large angle due to its design and which is converted into a torque.

In einer vorteilhaften Ausgestaltung der Erfindung ist die Getriebestufe, wie im Anspruch 3 dargelegt, als Bandgetriebe ausgebildet. Mit Hilfe eines Bandgetriebes kann eine spielfreie Erzeugung des Drehmoments an der Schwenkwelle erfolgen. Dies ist hinsichtlich einer exakten Steuerung des Spulenrahmens und damit hinsichtlich eines exakt eingestellten Spulenauflagedrucks vorteilhaft.In an advantageous embodiment of the invention Gear stage, as set out in claim 3, as a belt gear educated. With the help of a belt transmission, a backlash-free generation of torque on the swivel shaft respectively. This is in terms of precise control of the Coil frame and therefore in terms of one set bobbin support pressure advantageous.

Der Drehmomenterzeuger kann in einer alternativen Ausführungsform auch direkt mit einer Antriebswelle des Antriebselementes verbunden sein, wodurch sich eine unmittelbare Ansteuerung des Drehmomenterzeugers durch das Antriebselement ergibt. Die Anzahl der erforderlichen Bauteile wird dadurch verringert (Anspr.4).The torque generator can be in an alternative Embodiment also directly with a drive shaft Drive element connected, whereby a direct control of the torque generator by the Drive element results. The number of required Components are thereby reduced (Claim 4).

Wie im Anspruch 5 beschrieben, ist in vorteilhafter Ausgestaltung der Erfindung vorgesehen, dass zwischen Antriebselement und Drehmomenterzeuger eine weitere Getriebestufe angeordnet ist. Der Drehmomenterzeuger ist damit zwischen zwei Getrieben bzw. zwischen zwei Getriebestufen angeordnet, wodurch sich ein äußerst flexibler Aufbau der erfindungsgemäßen Vorrichtung ergibt. Beispielsweise kann als Antriebselement ein schwacher und kostengünstiger Schrittmotor eingesetzt werden.As described in claim 5, is advantageous Embodiment of the invention provided that between Drive element and torque generator another Gear stage is arranged. The torque generator is thus between two gears or between two Gear stages arranged, which makes it extremely flexible Structure of the device according to the invention results. For example, a weak and cost-effective stepper motor can be used.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung im Zusammenhang mit den Zeichnungen.Further features and advantages of the invention result from the following description in connection with the Drawings.

Fig. 4Fig. 4
eine Draufsicht auf ein Bandgetriebe gemäß der Fig. 3.a plan view of a belt transmission according to the Fig. 3.

In den schematischen Darstellungen der Fig.1 und der Fig.2 ist ein Spulstellengehäuse 10 einer Textilmaschine zu erkennen, an dem ein Spulenrahmen 12 mittels einer Schwenkwelle 14 begrenzt drehbar gelagert ist.
Im Spulenrahmen 12 ist drehbar eine Spule 16 gehaltert, die mittels Reibungskraft von einer Walze 18 angetrieben wird.
Um einen vorbestimmten Auflagedruck der Spule 16 auf der Walze 18 zu realisieren, wird die Schwenkwelle 14 des Spulenrahmens 12 mit einem definierten, einstellbaren Drehmoment beaufschlagt, das in der Regel entlastend auf den Spulenrahmen 12 wirkt.
Ein solcher vorbestimmter, gleichmäßiger Auflagedruck ist bei der Herstellung von Kreuzspulen sehr wichtig, da anderenfalls nicht nur das äußere Erscheinungsbild der Spulen sondern auch deren Ablaufverhalten negativ beeinflußt wird.1 and 2 show a bobbin case 10 of a textile machine, on which a bobbin frame 12 is rotatably supported to a limited extent by means of a pivot shaft 14.
A spool 16 is rotatably held in the spool frame 12 and is driven by a roller 18 by means of frictional force.
In order to achieve a predetermined contact pressure of the coil 16 on the roller 18, the pivot shaft 14 of the coil frame 12 is acted upon by a defined, adjustable torque, which generally has a relieving effect on the coil frame 12.
Such a predetermined, even contact pressure is very important in the production of cross-wound bobbins, since otherwise not only the outer appearance of the bobbins but also their running behavior will be negatively influenced.

In Bildstörbereichen ist dahingegen das Einleiten eines definierten Schlupfes zwischen Spule 16 und Walze 18 wünschenswert, wozu das am Spulenrahmen 12 wirksame Drehmoment vergrößert und dadurch der Auflagedruck der Spule 16 auf der Walze 18 definiert verringert wird.In contrast, in image interference areas, the initiation of a defined slip between coil 16 and roller 18th desirable, what the effective on the coil frame 12 Torque increases and thus the contact pressure of the coil 16 defined on the roller 18 is reduced.

Wie in den Zeichnungen dargestellt, ist die Schwenkwelle 14 einerseits mit dem Spulenrahmen 12 und andererseits mit einem Zahnrad 20 einer Untersetzungsgetriebestufe drehfest verbunden. Das Zahnrad 20 kämmt mit einem Ritzel 22, das mit einer Anschlagplatte 24 drehfest verbunden und auf einem Achsstummel 26 drehbar gelagert ist.
Der Achsstummel 26 ist wiederum am Spulstellengehäuse 10 der Textilmaschine befestigt. An der Anschlagplatte 24 ist mit einem ihrer Enden eine Spiralfeder 28 befestigt, die mit ihrem anderen Ende mit einem Verstellzahnrad 30 verbunden ist, das mit einem Motorritzel 32 eines elektrischen Schrittmotors 34 kämmt.As shown in the drawings, the pivot shaft 14 is connected on the one hand to the spool frame 12 and on the other hand to a gear 20 of a reduction gear stage. The gear 20 meshes with a pinion 22, which is connected in a rotationally fixed manner to a stop plate 24 and is rotatably mounted on an axle stub 26.
The stub shaft 26 is in turn attached to the winding unit housing 10 of the textile machine. On the stop plate 24, one end of a spiral spring 28 is fastened, the other end of which is connected to an adjusting gear 30 which meshes with a motor pinion 32 of an electric stepping motor 34.

Die Spiralfeder 28 ist an dem Verstellzahnrad 30 beispielsweise mit Hilfe von drei Befestigungsbolzen 36, 38 und 40 befestigt. Hierzu wird ein Ende der Spiralfeder 28 zwischen die Bolzen 36, 38 und 40 eingespannt und hält in dieser Position durch ihre Eigenspannung. An der Anschlagplatte 24 ist das andere Ende der Spiralfeder 28 mit zwei Bolzen 42 und 44 befestigt.The spiral spring 28 is on the adjusting gear 30 for example with the aid of three fastening bolts 36, 38 and 40 attached. For this purpose, one end of the spiral spring 28 clamped between the bolts 36, 38 and 40 and holds in this position due to its internal tension. At the Stop plate 24 is the other end of the coil spring 28 with two bolts 42 and 44 attached.

Wird das Verstellzahnrad 30 relativ zu der Anschlagplatte 24 verdreht, wird die Spiralfeder 28 gespannt oder entspannt und erzeugt dadurch eine auf die Anschlagplatte 24 wirkende Kraft, die mit Hilfe des Ritzels 22, des Zahnrads 20 und der Schwenkwelle 14 in ein auf den Spulenrahmen 12 wirkendes Drehmoment umgesetzt wird.
Eine relative Drehung zwischen dem Verstellzahnrad 30 und der Flügelplatte 24 ist durch den Bolzen 40 begrenzt, wobei zwei Endstellungen der Anschlagplatte 24 definiert sind. Eine erste Endstellung ist durch das Anschlagen einer ersten Kante 46 eines ersten, sich radial erstreckenden Vorsprungs der Anschlagplatte 24 an dem Bolzen 40 definiert. Eine zweite Endstellung ist durch das Anschlagen einer zweiten Kante 48 eines zweiten, sich radial von dem Achsstummel 26 aus entgegengesetzt zu dem ersten Vorsprung erstreckenden Vorsprungs der Anschlagplatte 24 an dem Bolzen 40 definiert. Durch diese beiden Endstellungen sind die von der Spiralfeder 28 minimal bzw. maximal erzeugbare Kraft und das minimale bzw. maximale Drehmoment festgelegt.If the adjusting gear 30 is rotated relative to the stop plate 24, the coil spring 28 is tensioned or relaxed and thereby generates a force acting on the stop plate 24, which by means of the pinion 22, the gear 20 and the pivot shaft 14 into one acting on the spool frame 12 Torque is implemented.
A relative rotation between the adjusting gear 30 and the wing plate 24 is limited by the bolt 40, two end positions of the stop plate 24 being defined. A first end position is defined by striking a first edge 46 of a first, radially extending projection of the stop plate 24 on the bolt 40. A second end position is defined by the abutment of a second edge 48 of a second projection of the stop plate 24, which extends radially from the axle stub 26 in the opposite direction to the first projection, on the bolt 40. The minimum or maximum force that can be generated by the spiral spring 28 and the minimum or maximum torque are defined by these two end positions.

Zur Steuerung des Spulenrahmens 12 und damit des Auflagedrucks der Spule 16 auf der Walze 18 wird das Motorritzel 32 durch den Schrittmotor 34 um eine bestimmte Anzahl an Schritten in einer gewünschten Richtung verstellt. Dies bewirkt eine Verdrehung des Verstellzahnrades 30 und damit eine Vor- oder Entspannung der Spiralfeder 28. Durch die Vor- oder Entspannung der Spiralfeder 28 verändert sich die von der Spiralfeder 28 erzeugte Kraft, die über die Bolzen 42, 44 auf die Anschlagplatte 24 und das mit dieser drehfest verbundene Ritzel 22 übertragen wird. Durch das Ritzel 22, das mit dem größeren Zahnrad 20 kämmt, wird die von der Spiralfeder 28 erzeugte Kraft in ein Drehmoment umgesetzt, das auf die Schwenkwelle 14 wirkt und dadurch den Auflagedruck der Spule 16 auf die Walze 18 verringert bzw. erhöht.To control the coil frame 12 and thus the The bearing pressure of the spool 16 on the roller 18 will be Motor pinion 32 by the stepper motor 34 by a certain Number of steps adjusted in a desired direction. This causes the adjusting gear 30 and thus a pre-or relaxation of the spiral spring 28. By the forward or relaxation of the coil spring 28 changes the force generated by the coil spring 28, which over the Bolts 42, 44 on the stop plate 24 and with this rotatably connected pinion 22 is transmitted. By the Pinion 22, which meshes with the larger gear 20, the force generated by the coil spring 28 into a torque implemented, which acts on the pivot shaft 14 and thereby Contact pressure of the coil 16 on the roller 18 reduced or elevated.

Da das Ritzel 22 und das Zahnrad 20 eine Untersetzungsgetriebestufe bilden, reicht eine relativ kleine Kraft der Spiralfeder 28 aus, um an der Schwenkwelle 14 ein relativ großes Drehmoment zu erzeugen. Die Spiralfeder 28 kann damit vergleichsweise schwach und kostengünstig ausgelegt werden. Since the pinion 22 and the gear 20 a Form a reduction gear stage, a relatively small is enough Force of the coil spring 28 to a on the pivot shaft 14 to generate relatively large torque. The coil spring 28 can be comparatively weak and inexpensive be interpreted.

In einer alternativen (nicht dargestellten) Ausführungsform ist vorgesehen, daß der Drehmomenterzeuger im Bereich einer zweiten, aus dem Motorritzel 32 und dem Verstellzahnrad 30 bestehenden Untersetzungsgetriebestufe angeordnet ist.
Auf diese Weise kann auch mit einem schwachen und kostengünstigen Schrittmotor 34 ein hohes Drehmoment an der Schwenkwelle 14 erzeugt werden. Die erfordeliche Vorspannung der Spiralfeder 28 ist in diesem Fall allerdings nur unter Inkaufnahme eines relativ großen Verstellweges erreichbar.In an alternative (not shown) embodiment it is provided that the torque generator is arranged in the region of a second reduction gear stage consisting of the motor pinion 32 and the adjusting gear 30.
In this way, a high torque can be generated on the pivot shaft 14 even with a weak and inexpensive stepper motor 34. The required preload of the spiral spring 28 can, however, only be achieved in this case by accepting a relatively large adjustment path.

In der Fig. 2 sind im Sinne einer übersichtlicheren Darstellung der Spulenarm 12, die Spule 16 und die Walze 18 nicht dargestellt.
Wie der Darstellung der Fig. 2 zu entnehmen ist, wird bei der dargestellten Ausführungsform ein Drehmomenterzeuger durch das Verstellzahnrad 30 mit den Bolzen 36, 38 und 40, die Spiralfeder 28 und die Flügelplatte 24 mit den Bolzen 42 und 44 sowie dem Ritzel 22 gebildet.2, the coil arm 12, the coil 16 and the roller 18 are not shown in the sense of a clearer representation.
As can be seen from the illustration in FIG. 2, in the embodiment shown, a torque generator is formed by the adjusting gear 30 with the bolts 36, 38 and 40, the spiral spring 28 and the wing plate 24 with the bolts 42 and 44 and the pinion 22.

Die Fig. 3 und 4 zeigen schematisch ein Bandgetriebe, das bei einer weiteren Ausführungsform der Erfindung eingesetzt wird. Eine Schwenkwelle 51 eines Spulenrahmens ist dabei in der Fig. 4 lediglich durch eine strichpunktierte Linie angedeutet.
Mit der Schwenkwelle 51 ist ein Übertragungshebel 52 drehfest verbunden, der einen zur Schwenkwelle 51 zentrischen Zylinderabschnitt 54 aufweist. An Befestigungspunkten 56 und 58 des Zylinderabschnitts 54 ist jeweils ein Band 60 bzw. 62 befestigt. Die Bänder 60 und 62, die vorzugsweise aus Stahl bestehen, verlaufen von dem Zylinderabschnitt 54 zu einer mit einem Drehmomenterzeuger verbundenen Antriebswelle 64, wobei beide Bänder 60 und 62 wendelförmig auf die Antriebswelle 64 aufgewickelt sind. 3 and 4 schematically show a belt transmission which is used in a further embodiment of the invention. A pivot shaft 51 of a coil frame is only indicated in FIG. 4 by a dash-dotted line.
A transmission lever 52 is connected in a rotationally fixed manner to the pivot shaft 51 and has a cylinder section 54 that is central to the pivot shaft 51. A band 60 and 62 is fastened to fastening points 56 and 58 of the cylinder section 54. The belts 60 and 62, which are preferably made of steel, run from the cylinder section 54 to a drive shaft 64 connected to a torque generator, both belts 60 and 62 being wound helically on the drive shaft 64.

Die Befestigungspunkte 56 und 58 auf dem Zylinderabschnitt 54 liegen dabei bezüglich der Antriebswelle 64, an der das Band 60 bzw. das Band 62 an einem Befestigungspunkt 66 bzw. 68 befestigt ist, auf entgegengesetzten Seiten.The attachment points 56 and 58 on the cylinder section 54 lie with respect to the drive shaft 64 on which the belt 60 or the band 62 at an attachment point 66 or 68 is attached on opposite sides.

Das bedeutet, eine Rotation der Antriebswelle 64 verursacht eine Auf- und Abwickelbewegung der Bänder 60, 62, die in eine Schwenkbewegung des Übertragungshebels 52 und somit des Spulenrahmens umgesetzt wird.
Das in den Fig. 3 und 4 dargestellte Bandgetriebe arbeitet weitestgehend spielfrei und hysteresefrei.This means that a rotation of the drive shaft 64 causes a winding and unwinding movement of the tapes 60, 62, which is converted into a pivoting movement of the transmission lever 52 and thus of the spool frame.
The belt transmission shown in FIGS. 3 and 4 operates largely free of play and free of hysteresis.
