Description

Die Erfindung betrifft ein Fadenliefergerät zur Zufuhr eines Fadens zu einer Textilmaschine, insbesondere zu einer Rundstrickmaschine, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a yarn feeding device for feeding a yarn to a textile machine, in particular to a circular knitting machine, according to the preamble of claim 1.

Ein als Garnspeicher-Zuführvorrichtung bezeichnetes Fadenliefergerät mit einer Gamspeicher-Trommel und einer Welle für die Trommel ist aus der DE 3104516 bekannt. Bei diesem Gerät wird von einer Garnspule kommendes Garn in mehreren Windungen auf die Trommel gewunden. Das gespeicherte Garn wird in der erforderlichen Weise, zum Beispiel mit gesteuerter Spannung, abgezogen, und zwar unabhängig von der Geschwindigkeit, mit der es anfangs auf die Zuführvorrichtung aufgewickelt wurde. Im Betrieb nähert sich das Garn der Garnzuführvorrichtung über eine Führungsöse, durchläuft zwei Spannvorrichtungen und wird auf der sich drehenden Trommel aufgewickelt. Das Garn wird von der Trommel abgezogen, um von einer Textilmaschine bei gleichbleibender Spannung aufgenommen zu werden.A yarn feeding apparatus called a yarn feeding apparatus having a chamfering drum and a shaft for the drum is known in the art DE 3104516 known. In this machine, yarn coming from a yarn package is wound in several turns on the drum. The stored yarn is withdrawn in the required manner, for example with controlled tension, regardless of the speed with which it was initially wound on the feeder. In operation, the yarn approaches the yarn feeding device via a guide eyelet, passes through two tensioning devices and is wound on the rotating drum. The yarn is withdrawn from the drum to be picked up by a textile machine at a constant tension.

Im Unterschied zu einem Garnspeicher-Fadenliefergerät ist bei einem als Positiv-Fadenliefergerät ausgebildeten Fadenliefergerät die Länge und damit die Menge des gelieferten Fadens abhängig von der Drehgeschwindigkeit des Fadenlieferrades. Bei einem solchen Fadenliefergerät wird der von der Spule abgezogene Faden mehrfach um das Fadenlieferrad gewickelt und proportional zur Drehgeschwindigkeit des Fadenlieferrades, d. h. positiv, an die Textilmaschine geliefert.In contrast to a yarn storage yarn feeding device in a trained as a positive yarn feeding device yarn feeding device, the length and thus the amount of the supplied yarn depends on the rotational speed of the yarn feed wheel. In such a yarn feeding device, the thread withdrawn from the spool is wound several times around the yarn feed wheel and proportional to the rotational speed of the yarn feed wheel, d. H. positive, delivered to the textile machine.

Ein als Positiv-Fadenliefergerät betreibbares Fadenliefergerät ist in der WO 2007/042057 A1 , die den Oberbegriff des Anspruchs 1 zugrunde liegt, beschrieben. Das Fadenliefergerät weist ein Fadenlieferrad, eine Welle, an der das Fadenlieferrad über ein Verbindungsmittel angeordnet ist, und einen Halter, an dem die Welle drebar gelagert ist, auf. Der Halter ist fadeneinlaufseitig, d. h. im Fadenverlauf vor dem Fadenlieferrad, mit einer Fadeneinlauföse, einer Fadenbremse, einer Fadenlauföse und bedarfsweise mit einem Knotenfänger versehen.An operable as a positive yarn feeding device yarn feeding device is in the WO 2007/042057 A1 , which is based on the preamble of claim 1 described. The yarn feeding device has a yarn feed wheel, a shaft on which the yarn feed wheel is arranged via a connecting means, and a holder on which the shaft is rotatably supported. The holder is yarn inlet side, ie provided in the yarn path in front of the yarn feed wheel, with a yarn inlet eye, a yarn brake, a thread running eye and, if necessary, with a knot catcher.

Ein weiteres als Positiv-Fadenliefergerät betreibbares Fadenliefergerät ist in der WO 2008/043371 A1 beschrieben. Das Fadenliefergerät umfasst ein Fadenlieferrad, eine Welle, die sich in Gebrauch vertikal erstreckt und an der das Fadenlieferrad angeordnet ist, und einen Träger mit einem oberen und einem unteren Schenkel, an denen die Welle drehbar gelagert ist. Der obere Schenkel des Trägers trägt ein als eine Fadenleitöse ausgebildetes Fadeneinlaufelement und unterhalb des Fadeneinlaufelementes einen Knotenfänger. Eine Fadenbremse und ein Fadeneinlauffühler sind an dem unteren Schenkel angeordnet. Fadeneinlaufelement, Knotenfänger und Fadenbremse befinden sich im Fadenverlauf vor dem Fadenlieferrad. Der Knotenfänger wird beispielsweise durch ein geschlitztes Blech gebildet, durch dessen Schlitz der Faden vorzugsweise umlenkungsfrei und im Idealfall berührungslos läuft.Another as a positive yarn feeding device operable yarn feeding device is in the WO 2008/043371 A1 described. The yarn feeding device comprises a yarn feed wheel, a shaft which extends vertically in use and on which the yarn feed wheel is arranged, and a carrier having an upper and a lower leg, on which the shaft is rotatably mounted. The upper leg of the wearer carries a trained as a Fadenleitöse yarn inlet element and below the yarn inlet element a node catcher. A yarn brake and a yarn inlet sensor are arranged on the lower leg. Thread inlet element, knot catcher and yarn brake are in the yarn path in front of the yarn feed wheel. The knot catcher is formed, for example, by a slotted plate, through the slot of which the thread preferably runs deflection-free and ideally without contact.

Ein Knotenfänger dient dazu, unerlaubte Dickstellen vom Faden zu entfernen. Dickstellen sind z. B. Fertigungsfehler im Verlauf des Fadens, Knoten an Verbindungsstellen des Fadens sowie am Faden anhaftende Fremdpartikel, wie Fasern, Fadenreste oder Schmutzpartikel. Beim Auftreten einer unerlaubten Dickstelle wird der Faden am Knotenfänger gestoppt und reißt.A knot catcher serves to remove unauthorized thick places from the thread. Thick places are z. As manufacturing defects in the course of the thread, knots at joints of the thread and the thread adhering foreign particles, such as fibers, thread residue or dirt particles. When an unauthorized thick spot occurs, the thread on the knotter is stopped and tears.

Die Funktion des Knotenfängers ist bei einer Anordnung des Knotenfängers im Fadenverlauf vor der Fadenbremse nicht immer gewährleistet. Der Faden wird je nach Art des Fadens mit kleineren oder größeren Spannungsschwankungen von der Spule abgezogen, wobei die Spannungsschwankungen dazu führen können, dass der Faden zu locker oder zu straff durch den Knotenfänger läuft. Durch Vibrationen des abgezogenen Fadens, kann dieser den Knotenfänger berühren. Dies kann zu einer Beschädigung des Fadens führen, ohne dass eine unerlaubte Dickstelle aufgetreten ist.The function of the knot catcher is not always guaranteed in an arrangement of the knotter in the thread path before the thread brake. Depending on the type of thread, the thread is pulled off the reel with smaller or larger voltage fluctuations, whereby the voltage fluctuations can lead to the thread running too loosely or too tightly through the knot catcher. By vibrations of the withdrawn thread, this can touch the knot catcher. This can lead to damage of the thread without an unauthorized thick spot has occurred.

Die Aufgabe ist durch die Merkmale des Anspruchs 1 gelöst.The object is solved by the features of claim 1.

Ein erfindungsgemäßes Fadenliefergerät zur Zufuhr eines Fadens zu einer Textilmaschine, insbesondere zu einer Rundstrickmaschine, ist mit einem Fadenlieferrad und mit einer Antriebswelle für das Fadenlieferrad versehen. Die Drehachse der Antriebswelle verläuft im Betrieb vertikal. An der Antriebswelle ist das Fadenlieferrad angeordnet, wobei es im Betrieb drehfest mit der Antriebswelle verbunden ist. In einer Ausführungsform weist das Fadenliefergerät ein Fadenauslaufelement auf, durch das der Fadenabzug von dem Fadenlieferrad als Schrägabzug ausgebildet ist. An einer Rundstrickmaschine ist eine Vielzahl von Fadenliefergeräten vorgesehen. Beim Einsatz von Positiv-Fadenliefergeräten sind die Antriebswellen der Fadenliefergeräte mit einer gemeinsamen mit der Rundstrickmaschine verbundenen Antriebeinrichtung versehen. Dazu weisen die Antriebswellen an ihren den Fadenrändem entgegengesetzten Enden z. B. Riemenschreiben auf. Die Antriebseinrichtung umfasst in diesem Fall einen Antriebsriemen, der in Betrieb über die Riemenscheiben der angeschlossenen Fadenlieferräder läuft und der über ein Getriebe von einem Antrieb der Rundstrickmaschine angetrieben ist. D. h. die Fadenliefergeräte sind in Betrieb alle gleich durch den Antrieb der Rundstrickmaschine angetriebenAn inventive yarn feeding device for feeding a yarn to a textile machine, in particular to a circular knitting machine, is provided with a yarn feed wheel and with a drive shaft for the yarn feed wheel. The axis of rotation of the drive shaft extends vertically during operation. On the drive shaft, the yarn feed wheel is arranged, wherein it is rotatably connected in operation with the drive shaft. In one embodiment, the yarn feeding device has a yarn outlet element, by which the yarn withdrawal from the yarn feed wheel is formed as a skewed withdrawal. On a circular knitting machine a plurality of yarn feeding devices is provided. When using positive yarn feeding devices, the drive shafts of the yarn feeding devices are provided with a common drive device connected to the circular knitting machine. For this purpose, the drive shafts at their ends opposite the thread edges z. B. belt writing on. The drive device in this case comprises a drive belt, which in operation via the pulleys of the connected Thread delivery wheels runs and is driven by a gear from a drive of the circular knitting machine. Ie. The yarn feeding devices are all driven in the same way by the drive of the circular knitting machine

Das Fadenliefergerät umfasst einen Träger mit einer Befestigungseinrichtung zur Befestigung des Fadenliefergerätes an der Textilmaschine und mit einer Lagereinrichtung zur Lagerung der Antriebswelle. Das Fadenliefergerät ist mit mindestens einem Fadenfühler versehen. Der Fadenfühler ist als Fadeneinlauffühler ausgebildet und im Fadenverlauf vor dem Fadenlieferrad angeordnet oder als Fadenauslauffühler ausgebildet und im Fadenverlauf hinter dem Fadenlieferrad angeordnet. In einer Alternative weist das Fadenliefergerät einen Fadeneinlauffühler und einen Fadenauslauffühler auf.The yarn feeding device comprises a carrier with a fastening device for fastening the yarn feeding device to the textile machine and with a bearing device for supporting the drive shaft. The yarn feeding device is provided with at least one yarn feeler. The yarn feeler is designed as a yarn inlet sensor and arranged in the yarn path in front of the yarn feed wheel or formed as a thread outlet sensor and arranged in the yarn path behind the yarn feed wheel. In an alternative, the yarn feeding device has a yarn inlet sensor and a thread outlet sensor.

Das Fadenliefergerät weist eine erste Fadenbremse, mindestens eine zweite Fadenbremse und einen Knotenfänger auf. Die beiden Fadenbremsen und der Knotenfänger befinden sich im Fadenverlauf vor dem Fadenlieferrad, d. h. im Fadeneinlaufbereich. Erfindungsgemäß ist der Knotenfänger zwischen den beiden Fadenbremsen angeordnet.The yarn feeding device has a first yarn brake, at least one second yarn brake and a knot catcher. The two thread brakes and the knot catcher are in the thread path in front of the yarn feed wheel, d. H. in the yarn inlet area. According to the invention, the knot catcher is arranged between the two thread brakes.

Im Betrieb wird der von der Spule abgezogene Faden in der ersten Fadenbremse mit einer ersten Bremskraft gebremst. Der durch die erste Fadenbremse vorgespannte Faden durchläuft den Knotenfänger. Der vorgespannte Faden wird in der zweiten Fadenbremse mit einer zweiten Bremskraft weiter gebremst.During operation, the thread withdrawn from the spool in the first thread brake is braked with a first braking force. The biased by the first yarn brake thread passes through the knot catcher. The prestressed thread is further braked in the second thread brake with a second braking force.

Die erfindungsgemäße Anordnung einer ersten Fadenbremse im Fadenverlauf vor dem Knotenfänger und einer zweiten Fadenbremse im Fadenverlauf nach dem Knotenfänger ermöglicht, dass der Faden vorgespannt durch den Knotenfänger läuft und anschließend dem Fadenlieferrad mit einer auf die Art des Fadens abgestimmten Fadenspannung zugeführt wird. Vibrationen in Querrichtung dem Fadenverlauf sowie Spannungsschwankungen des Fadens vor dem Knotenfänger werden durch die erste Fadenbremse vermieden. Der Faden läuft beruhigt und definiert durch den Knotenfänger.The arrangement according to the invention of a first thread brake in the course of the thread in front of the knotter and a second thread brake in the course of the thread after the knot catcher allows the thread to run biased through the knotter and then fed to the thread delivery wheel with a thread tension tuned to the type of thread. Vibrations in the transverse direction of the thread course as well as tension fluctuations of the thread in front of the knot catcher are avoided by the first thread brake. The thread runs smoothly and defined by the knot catcher.

Besonders vorteilhaft ist die erfindungsgemäße Anordnung bei dem Einsatz von Multifilamentgarn, insbesondere von Multifilamentgarn mit 40 bis 100 Einzelfilamenten, ggf. texturiert. Bei der Verwendung von Multifilamentgarn besteht dass Problem der Filamentaufschiebung vor der Fadenbremse, wenn die Bremskraft der Fadenbremse zu hoch ist. Bei der Anordnung zweier Fadenbremsen bewirkt die erste Fadenbremse durch die Einstellung einer ersten Fadenspannung auch eine gewisse Bündelung der Filamente des Multifilamentgarn. D. h. die Vorspannung wirkt wie eine Glättung des Fadens. Die Bremskraft der zweiten Fadenbremse kann daher so gering eingestellt werden, dass eine Filamentaufschiebung und damit eine Filamentaufspaltung auf dem Fadenlieferrad vermieden wird. Durch die Vorspannung des Faden ist dennoch ein sicherer Lagenvorschub auf dem Fadenlieferrad ohne Filamentaufschiebung gewährleistet.The arrangement according to the invention is particularly advantageous in the use of multifilament yarn, in particular of multifilament yarn with 40 to 100 individual filaments, optionally textured. When using multifilament yarn, there is a problem of filament suspending in front of the thread brake when the braking force of the thread brake is too high is high. In the arrangement of two thread brakes causes the first thread brake by setting a first thread tension and a certain bundling of the filaments of multifilament yarn. Ie. the bias acts as a smoothing of the thread. The braking force of the second yarn brake can therefore be set so low that a Filamentaufschiebung and thus a Filamentaufspaltung on the yarn feed wheel is avoided. Due to the bias of the thread a secure position feed is still guaranteed on the yarn feed wheel without Filamentaufschiebung.

Vorzugsweise ist eine Schlitzbreite des Knotenfängers einstellbar.Preferably, a slot width of the node catcher is adjustable.

Die jeweilige Fadenbremse ist z. B. als Tellerbremse, als Umschlingungsbremse oder als Kompensationsbremse, z. B. als Krokodilbremse, ausgebildet. Vorzugsweise ist zumindest eine der beiden Fadenbremsen als Tellerbremse mit einer Vibrationseinrichtung, im Folgenden als Vibrationsbremse bezeichnet, ausgebildet. Eine Vibrationsbremse ist in der EP 0499218 B1 beschrieben, deren Inhalt hiermit in diese Anmeldung aufgenommen ist. Die Vibration der Fadenbremse begünstigt die Drehung beider Bremsteller der Fadenbremse. Durch die Drehung der Bremsteller wird verhindert, dass sich der Faden an einer bestimmten Stelle einsägt. Sie ermöglicht auch, dass Schmutz aus der Fadenbremse heraus transportiert wird. In einer Alternative ist die im Fadenverlauf erste Fadenbremse als Vibrationsbremse ausgebildet.The respective yarn brake is z. B. as a disk brake, as a wrap brake or compensation brake, z. B. as a crocodile brake formed. Preferably, at least one of the two thread brakes is designed as a disk brake with a vibration device, referred to below as a vibration brake. A vibration brake is in the EP 0499218 B1 described, the content of which is hereby incorporated in this application. The vibration of the thread brake favors the rotation of both brake discs of the thread brake. The rotation of the brake plates prevents the thread from cutting in at a certain point. It also allows dirt to be transported out of the thread brake. In an alternative, the first thread brake in the course of the thread is designed as a vibration brake.

In einer weiteren Alternative ist die im Fadenverlauf zweite Fadenbremse als Vibrationsbremse ausgebildet. Dies ist eine konstruktiv einfach zu realisierende Alternative.In a further alternative, the second thread brake in the course of the thread is designed as a vibration brake. This is a structurally easy to implement alternative.

Vorzugsweise ist eine der Fadenbremsen als eine Kompensationsfadenbremse ausgebildet. Eine Kompensations-fadenbremse nimmt bei geringer Fadenspannung eine bestimmte Fadenlänge auf und erhöht dabei die Fadenspannung. Bei hoher Fadenspannung wird die aufgenommene Fadenlänge wieder freigegeben. In einer Ausführungsform ist die Kompensationsbremse als Krokodilbremse oder als Rechenspanner ausgebildet. Die Anordnung einer Kompensationsbremse, bei der die Fadenspannung durch Umlenkung des Fadens erhöht wird, in Kombination mit z. B. einer Tellerbremse, bei der der Faden durch Flächendruck gebremst wird, erhöht den Einsatzbereich des Fadenliefergerätes. Insbesondere können ultrafeine Filamentgarne, bei denen Tellerbremsen alleine ggf. unruhig bremsen, mit einer solchen Kombination sicher geliefert werden.Preferably, one of the thread brakes is designed as a compensation thread brake. A compensation thread brake absorbs a certain length of thread with low thread tension and thereby increases the thread tension. At high thread tension the recorded thread length is released again. In one embodiment, the compensation brake is designed as a crocodile brake or as a rake tensioner. The arrangement of a compensation brake in which the thread tension is increased by deflection of the thread, in combination with z. As a disk brake, in which the thread is braked by surface pressure, increases the scope of the yarn feeding device. In particular, ultrafine filament yarns, where plate brakes alone possibly restless braking, be delivered safely with such a combination.

Die beiden Fadenbremsen und der Knotenfänger sind vorzugsweise so in dem Fadenverlauf angeordnet, z. B. im Wesentlichen auf einer Geraden angeordnet, dass der Faden gerade durch den Knotenfänger verläuft.The two thread brakes and the knot catcher are preferably arranged in the thread path, z. B. arranged substantially on a straight line, that the thread runs straight through the knot catcher.

Das Fadenliefergerät weist Fadenleitvorrichtungen auf, die vorzugsweise so angeordnet sind, dass der Fadenverlauf zu der ersten Fadenbremse und/oder ausgehend von dem zweiten Faden in einem spitzen Winkel zu der Geraden verläuft. Durch die Fadenleitvorrichtungen wird ein Fadenverlauf eingestellt, der an der ersten und/oder an der zweiten Fadenbremse um einen spitzen Winkel abgelenkt wird. Bei der Umlenkung wird der Faden im Betrieb z. B. an ein Element der entsprechenden Fadenbremse gedrückt. Ein Herausspringen des Fadens aus der Fadenbremse wird vermieden. Der spitze Winkel beträgt z. B. 5° bis 20°.The yarn feeding device has thread guiding devices, which are preferably arranged so that the yarn path to the first yarn brake and / or extending from the second yarn at an acute angle to the straight line. By the Fadenleitvorrichtungen a thread course is set, which is deflected at the first and / or at the second yarn brake at an acute angle. When deflecting the thread during operation z. B. pressed to an element of the corresponding yarn brake. Jumping out of the thread from the yarn brake is avoided. The acute angle is z. B. 5 ° to 20 °.

In einer Ausführungsform ist die erste Fadenbremse im Betrieb vertikal oberhalb der zweiten Fadenbremse angeordnet, wobei der Fadenverlauf im Wesentlichen vertikal durch den Knotenfänger eingestellt ist.In one embodiment, the first yarn brake is arranged vertically above the second yarn brake during operation, wherein the yarn path is set substantially vertically by the knotter.

Das Fadenliefergerät weist vorzugsweise mindestens ein erstes Fadeneinlaufleitelement auf, durch das der Fadenverlauf zu der ersten Fadenbremse in einem spitzen Winkel zur Vertikalen eingestellt ist.The yarn feeding device preferably has at least one first yarn inlet guide element, by which the yarn path to the first yarn brake is set at an acute angle to the vertical.

Das Fadenliefergerät weist vorzugsweise eine Fadenleitvorrichtung auf, durch die der Fadenverlauf ausgehend von der zweiten Fadenbremse in einem spitzen Winkel zur Vertikalen eingestellt ist. Die Fadenleitvorrichtung kann durch ein zweites Fadenleitelement und/oder durch einen Fadenfühler gebildet sein.The yarn feeding device preferably has a thread guiding device, by means of which the yarn course is adjusted starting from the second yarn brake at an acute angle to the vertical. The thread guiding device can be formed by a second thread guide element and / or by a thread feeler.

In einer Ausführungsform umfasst das Fadenliefergerät einen Halter der an dem Träger befestigt ist. An dem Halter sind zumindest die beiden Fadenbremsen und der Knotenfänger angeordnet.In one embodiment, the yarn feeding device comprises a holder which is attached to the carrier. At least the two thread brakes and the knot catcher are arranged on the holder.

Vorzugsweise ist mindestens ein Fadenleitelement, z. B. das erste Fadeneinlaufleitelement, an dem Halter angeordnet. Vorzugsweise ist auch ein zweites Fadeneinlaufleitelement an dem Halter angeordnet.Preferably, at least one thread guide element, for. B. the first Fadeneinlaufleitelement arranged on the holder. Preferably, a second Fadeneinlaufleitelement is arranged on the holder.
