- the two guide elements form a thread guide fork, in which the thread is guided for laying on a spool.
- the design of the guide elements made of ceramic serves to counteract the abrasive effects of the thread to be laid at high speed on the guide elements.
- a disadvantage of the yarn guide according to the prior art has been found that the existing ceramic hollow guide elements, which are connected directly to the arm of the yarn guide, even with aggressive yarn, although no significant wear subject, but due to their low elongation at break easily break off the bending moments occurring in the high-frequency laying of the thread or at least flake off of these in guide elements that are additionally provided with rods in their interior.

- the flexural elastic rods should allow a deflection of up to ten degrees about their longitudinal axis.
- the guide elements should be arranged spaced apart by the flexurally elastic rods to the arm, so that an exposed bending region between the arm and the guide elements is formed.
- the arranged on the bending elastic rods guide elements form a corresponding thread guide section.
- a wear-free thread guide section for guiding the thread during installation is formed, on the other hand, a bending region is present, which can deform under load according to the modulus of elasticity of flexural elastic rods and thus keeps the load on the ceramic thread guide elements below their breaking elongation.
- the longitudinal extent of the bending region is between 1 mm and 10 mm.
- the longitudinal extent of the Bending range depends essentially on the elasticity of the material used for the flexural elastic rods respectively the permissible deflection to ensure the safe installation of the thread at high frequency traversing the thread guide, and the structural design of the thread guide and its positioning on a textile machine.
- the longitudinal extent of the bending region is such that the yarn to be laid by the yarn guide does not come into contact with the flexible elastic rods.
- the flexurally elastic rods should be designed so that they provide a high-frequency installation of the thread a secure hold of the guide elements on the arm by the flexurally elastic rods each extend at least partially into the guide element arranged thereon.
- the flexurally elastic rods may have a greater longitudinal extent than the guide elements.
- the respective flexurally elastic rod can extend completely in the interior of the thread guide element over its entire length in order to form the bending region between the arm and the guide elements and to achieve a sufficient attachment of the guide elements on the arm.
- the guide elements can be glued to the bending elastic rods. In this way, it is ensured that an unintentional release of the guide elements is avoided by the flexurally elastic rods. In addition, by a complete wetting of the joining surfaces is prevented by a gap formation between the guide member and the flexible elastic rod from each other due to vibrations during high-frequency Loosen the traversing of the thread guide for thread laying.
- the flexurally elastic rods may consist of a highly elastic material.
- the flexurally elastic rods may consist of a carbon fiber composite material.

- the low breaking strength and elasticity of the ceramic when used for the guide elements on the one hand and the low wear resistance of the flexurally elastic rods on the other hand are compensated in this way by the other material.
- the flexurally elastic rods can be connected to one another by a connecting element extending in the direction of movement of the thread guide, whose extension in the direction of movement of the thread guide is greater than transversely to this.
- An appropriately designed connecting element restricts the deflection of the guide elements in the direction of movement of the thread guide, the guide elements are cushioned hard.
- the deflection of the guide elements in the direction of yarn travel respectively the loading direction is almost not limited by an incoming thread loop, which corresponds to a soft suspension.
- Fig. 1 is a schematic view of a yarn guide 1 according to the invention shown.
- the yarn guide 1 is finger-shaped or pointer-shaped and has a tapering towards its free end course.
- the wider end of the thread guide 1 is connected to a single-motor drive 3, about the longitudinal axis of the yarn guide 1 is pivotable.
- a single-motor drive 3 about the longitudinal axis of the yarn guide 1 is pivotable.
- the yarn guide 1 is driven traversing means of its single-motor drive 3 over the spool width.
- the arm 5 of the thread guide 1 has at its free, narrower end two guide elements 6, 7 designed as cylindrical hollow bodies made of ceramic, which are fastened to the arm 5 in a positive and / or non-positive manner via a beige-elastic rod 8, 9, as in FIG Fig. 2 shown.

- a thread guide section 11 is formed on the guide elements 6, 7 and a bending region 10 between the arm 5 and the guide elements 6, 7 spaced therefrom.
- the bending region 10 formed by the spaced-apart arrangement serves to compensate for the forces acting on the guide elements 6, 7 during laying of the thread, in particular the bending moments, in that the bending region 10 can deform. This ensures that the load on the guide elements 6, 7 is kept below the breaking elongation.
- the guide elements 6, 7 are preferably connected to the respective flexurally elastic rod 8, 9 by gluing.

- the flexurally elastic rods 8, 9 consist of a carbon fiber composite material, for example carbon.
- the selection of materials is based inter alia on the maximum permissible deflection of the guide elements 6, 7 about their longitudinal axis, which should not exceed an angle of 10 °, to not adversely affect the laying of the thread by the high-frequency traversing of the thread guide 1.
- Fig. 3 shows a preferred embodiment of the thread guide 1, in which the flexurally elastic rods 8, 9 are interconnected by a connecting element 12.
- the connecting element 12 has in the direction of movement of the yarn guide 1, ie parallel to the coil axis, a greater extent than transverse to this. Accordingly, the flexurally elastic rods 8, 9 in the direction of movement of the thread guide 1 cushioned harder than in the thread running direction respectively the loading direction by an incoming thread loop.
Abstract
Description
Die vorliegende Erfindung betrifft einen Fadenführer, umfassend einen finger- oder zeigerförmig ausgebildeten Arm, der mit seinem einen Ende mit einer Antriebseinrichtung verbunden ist und mit seinem freien Ende zur Verlegung eines Fadens auf einer rotierenden Spule parallel zur Spulenachse zwei als Hohlkörper aus Keramik ausgebildete Führungselemente aufweist.The present invention relates to a yarn guide comprising a finger or pointer-shaped arm, which is connected at one end to a drive means and having its free end for laying a yarn on a rotating coil parallel to the coil axis two formed as a hollow body made of ceramic guide elements ,
Ein Fadenführer der eingangs genannten Art ist aus der
Als nachteilig an dem Fadenführer gemäß dem Stand der Technik hat sich erwiesen, dass die aus Keramik bestehenden hohlen Führungselemente, die ummittelbar mit dem Arm des Fadenführers verbunden sind, selbst bei aggressivem Garn zwar keinem nennenswerten Verschleiß unterliegen, jedoch auf Grund ihrer geringen Bruchdehnung in Folge der auftretenden Biegemomente bei der hochfrequenten Verlegung des Fadens leicht abbrechen beziehungsweise bei Führungselementen, die in ihrem Inneren zusätzlich mit Stäben versehen sind, von diesen zumindest abplatzen.A disadvantage of the yarn guide according to the prior art has been found that the existing ceramic hollow guide elements, which are connected directly to the arm of the yarn guide, even with aggressive yarn, although no significant wear subject, but due to their low elongation at break easily break off the bending moments occurring in the high-frequency laying of the thread or at least flake off of these in guide elements that are additionally provided with rods in their interior.
Der Erfindung liegt somit die Aufgabe zu Grunde, einen Fadenführer bereit zu stellen, der die genannten Nachteile des Standes der Technik vermeidet.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruches 1 gelöst.The invention is therefore based on the object to provide a yarn guide which avoids the disadvantages of the prior art.
This object is achieved by the characterizing features of
Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.Advantageous developments are the subject of the dependent claims.
Gemäß dem Anspruch 1 wird vorgeschlagen, dass die Führungselemente jeweils über biegeelastische Stäbe mit dem freien Ende des Armes verbunden sind. Durch die Verbindung der Führungselemente mit dem freien Ende des Armes über die biegelastischen Stäbe wird erreicht, dass das während der Verlegung auftretende Biegemoment von den biegeelastischen Stäben aufgenommen, wodurch die Belastung auf die Führungselemente kompensiert wird. Die biegeelastischen Stäbe sollten dabei eine Auslenkung von bis zu zehn Grad um ihre Längsachse ermöglichen.According to
Hierzu sollten die Führungselemente durch die biegeelastischen Stäbe zum Arm beabstandet angeordnet sein, so dass sich ein freiliegender Biegebereich zwischen dem Arm und den Führungselementen ausbildet. Die auf den biegeelastischen Stäben angeordneten Führungselemente bilden entsprechend einen Fadenführungsabschnitt aus. Auf diese Weise wird einerseits ein verschleißfreier Fadenführungsabschnitt zur Führung des Fadens während der Verlegung gebildet, andererseits ist ein Biegebereich vorhanden, der sich bei Belastung entsprechend dem Elastizitätsmodul der biegeelastischen Stäbe verformen kann und somit die Belastung an den aus Keramik bestehenden Fadenführungselementen unterhalb ihrer Bruchdehnung hält.For this purpose, the guide elements should be arranged spaced apart by the flexurally elastic rods to the arm, so that an exposed bending region between the arm and the guide elements is formed. The arranged on the bending elastic rods guide elements form a corresponding thread guide section. In this way, on the one hand, a wear-free thread guide section for guiding the thread during installation is formed, on the other hand, a bending region is present, which can deform under load according to the modulus of elasticity of flexural elastic rods and thus keeps the load on the ceramic thread guide elements below their breaking elongation.
Vorteilhafterweise beträgt die Längsausdehnung des Biegebereiches zwischen 1 mm und 10 mm. Die Längsausdehnung des Biegebereiches richtet sich dabei im Wesentlichen nach der Elastizität des für die biegeelastischen Stäbe eingesetzten Materiales respektive der zulässigen Auslenkung, um die sichere Verlegung des Fadens bei hochfrequenter Changierung des Fadenführers zu gewährleisten, sowie der konstruktiven Ausgestaltung des Fadenführers und seiner Positionierung an einer Textilmaschine. Die Längsausdehnung des Biegebereiches ist derart, dass das vom Fadenführer zu verlegende Garn nicht mit den biegeelastischen Stäben in Berührung kommt.Advantageously, the longitudinal extent of the bending region is between 1 mm and 10 mm. The longitudinal extent of the Bending range depends essentially on the elasticity of the material used for the flexural elastic rods respectively the permissible deflection to ensure the safe installation of the thread at high frequency traversing the thread guide, and the structural design of the thread guide and its positioning on a textile machine. The longitudinal extent of the bending region is such that the yarn to be laid by the yarn guide does not come into contact with the flexible elastic rods.
Die biegeelastischen Stäbe sollten so ausgeführt sein, dass sie bei hochfrequenter Verlegung des Fadens einen sicheren Halt der Führungselemente am Arm bieten, indem sich die biegeelastischen Stäbe jeweils zumindest abschnittsweise in das daran angeordnete Führungselement erstrecken.The flexurally elastic rods should be designed so that they provide a high-frequency installation of the thread a secure hold of the guide elements on the arm by the flexurally elastic rods each extend at least partially into the guide element arranged thereon.
Insbesondere können die biegeelastischen Stäbe eine größere Längsausdehnung aufweisen als die Führungselemente. Somit kann sich der jeweilige biegeelastische Stab vollständig im Inneren des Fadenführungselementes über dessen gesamte Länge erstrecken, um den Biegebereich zwischen dem Arm und den Führungselementen auszubilden und eine hinreichende Befestigung der Führungselemente am Arm zu erreichen.In particular, the flexurally elastic rods may have a greater longitudinal extent than the guide elements. Thus, the respective flexurally elastic rod can extend completely in the interior of the thread guide element over its entire length in order to form the bending region between the arm and the guide elements and to achieve a sufficient attachment of the guide elements on the arm.
In bevorzugter Weiterbildung der Erfindung können die Führungselemente auf den biegeelastischen Stäben festgeklebt sein. Auf diese Weise wird sichergestellt, dass ein unbeabsichtigtes Lösen der Führungselemente von den biegeelastischen Stäben vermieden wird. Zudem wird durch eine vollständige Benetzung der Fügeflächen verhindert, dass sich durch eine Spaltbildung zwischen dem Führungselement und dem biegeelastischen Stab diese voneinander auf Grund von Vibrationen während der mit hoher Frequenz erfolgenden Changierung des Fadenführers zur Fadenverlegung voneinander lösen.In a preferred embodiment of the invention, the guide elements can be glued to the bending elastic rods. In this way, it is ensured that an unintentional release of the guide elements is avoided by the flexurally elastic rods. In addition, by a complete wetting of the joining surfaces is prevented by a gap formation between the guide member and the flexible elastic rod from each other due to vibrations during high-frequency Loosen the traversing of the thread guide for thread laying.
Vorzugsweise können die biegeelastischen Stäbe aus einem hochelastischen Werkstoff bestehen. Insbesondere können die biegeelastischen Stäbe aus einem Kohlefaserverbundwerkstoff bestehen. Hier könnte beispielsweise Carbon zum Einsatz kommen. Die Materialkombination aus Keramik im Fadenführungsabschnitt und Kohlefaserverbundwerkstoff im Biegebereich stellt eine Lösung dar, die den Anforderungen an die Verschleißfestigkeit im Fadenführungsabschnitt und der erforderlichen Elastizität im Biegebereich gerecht wird. Die geringe Bruchfestigkeit und Elastizität der Keramik bei der Verwendung für die Führungselemente einerseits und die geringe Verschleißfestigkeit der biegeelastischen Stäbe andererseits werden auf diese Weise vom jeweils anderen Werkstoff ausgeglichen.Preferably, the flexurally elastic rods may consist of a highly elastic material. In particular, the flexurally elastic rods may consist of a carbon fiber composite material. For example, carbon could be used here. The material combination of ceramic in the thread guide section and carbon fiber composite material in the bending area represents a solution that meets the requirements for wear resistance in the thread guide section and the required elasticity in the bending area. The low breaking strength and elasticity of the ceramic when used for the guide elements on the one hand and the low wear resistance of the flexurally elastic rods on the other hand are compensated in this way by the other material.
In bevorzugter Weiterbildung können die biegeelastischen Stäbe durch ein sich in Bewegungsrichtung des Fadenführers erstreckendes Verbindungselement miteinander verbunden sein, dessen Ausdehnung in Bewegungsrichtung des Fadenführers größer ist als quer zu dieser. Ein entsprechend gestaltetes Verbindungselement beschränkt die Auslenkung der Führungselemente in der Bewegungsrichtung des Fadenführers, die Führungselemente werden hart abgefedert. Hingegen ist die Auslenkung der Führungselemente in Fadenlaufrichtung respektive der Belastungsrichtung durch eine einlaufende Fadenschlinge nahezu nicht eingeschränkt, was einer weichen Federung entspricht.In a preferred development, the flexurally elastic rods can be connected to one another by a connecting element extending in the direction of movement of the thread guide, whose extension in the direction of movement of the thread guide is greater than transversely to this. An appropriately designed connecting element restricts the deflection of the guide elements in the direction of movement of the thread guide, the guide elements are cushioned hard. By contrast, the deflection of the guide elements in the direction of yarn travel respectively the loading direction is almost not limited by an incoming thread loop, which corresponds to a soft suspension.
