Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Bilden einer Dreherkante, insbesondere für schützenlose Webmaschinen, umfassend einen Elektromotor mit einem Rotor, wobei der Rotor beabstandet zueinander mindestens zwei Führungselemente für die Dreherfäden aufweist.The invention relates to a device for forming a Leno edge, especially for defenseless weaving machines, comprising an electric motor with a rotor, the rotor spaced from each other at least two guide elements for which has leno threads.
Aus der DE 128 364 ist eine Vorrichtung zum Verzieren von
Geweben durch Schnurendreher bekannt. Hierbei werden bis zu
vier Fäden um eine Seele verdrillt. Die Verdrillung erfolgt
außerhalb des Faches, weshalb ein Abbinden des Schlußfadens
nicht möglich ist. Schlußendlich handelt es sich bei dieser
Vorrichtung nicht um eine Vorrichtung zum Bilden einer
Dreherkante.
Aus der US-A 36 13 741 ist eine Dreherkantenvorrichtung
bekannt, die einen antreibbaren Rotationskörper zeigt, der
endseitig kreuzweise angeordnete Rohre zur Führung von
Dreherfäden zeigt. Der Rotationskörper besitzt endseitig einen
mit dem Rotationskörper gekoppelten Drehtisch zur Aufnahme von
Spulen für die Dreherfäden. Hieraus folgt, daß die Spulen sich
bei Drehung des Rotationskörpers immer mitdrehen, was
bedeutet, daß eine hohe Masse beschleunigt und auch abgebremst
werden muß.From DE 128 364 a device for decorating fabrics by twine is known. Up to four threads are twisted around a soul. The twisting takes place outside the compartment, which is why it is not possible to tie the final thread. Finally, this device is not a device for forming a leno edge.
From US-A 36 13 741 a leno edging device is known, which shows a drivable rotary body, the ends of which have cross-arranged tubes for guiding leno threads. The end of the rotating body has a rotary table coupled to the rotating body for receiving bobbins for the leno threads. It follows from this that the coils always turn when the rotating body rotates, which means that a high mass must be accelerated and also braked.
Eine Vorrichtung der eingangs genannten Art ist aus der DE-PS 44 05 776 bekannt. Hierbei ist ein elektrisch ansteuerbarer Stellmotor vorgesehen, der eine Dreherscheibe antreibt, wobei die Dreherscheibe den Läufer des elektrisch ansteuerbaren Stellmotors bildet. Der Stator selbst ist durch ein Trägerteil an der Webmaschine anbringbar, und zwar vorzugsweise in einem zwischen den Längsstreben und Litzen liegenden Freiraum vor den ersten Webschäften der Webmaschine. Im einzelnen ist hierbei vorgesehen, daß die Dreherscheibe, die den Läufer des elektrisch ansteuerbaren Stellmotors bildet, als Führungselemente zwei einander gegenüberliegend angeordnete Öffnungen zum Durchführen jeweils eines Dreherfadens aufweist. Dieser bekannte Rotations-Kantendreher einer Webmaschine arbeitet nun derart, daß er einige hundert Umdrehungen in einer Richtung durchführt und hierbei nach jeweils einer Umdrehung einen Schußfaden abbindet. Es entsteht somit eine Volldreherkante. Auf der Seite der Zuführung der beiden Dreherfäden verdrillen sich diese Dreherfäden entsprechend der Anzahl der Umdrehungen der Dreherscheibe, so daß, um diese Verdrillung aufzuheben, eine Drehrichtungsumkehr angezeigt ist, mithin also die Dreherscheibe in genau die entgegengesetzte Richtung rotieren muß. Die Anzahl der Umdrehungen in jeder Richtung muß hierbei im zeitlichen Mittel gleich sein. Wurde keine Drehrichtungsumkehr vorgenommen werden, so würden die Dreherfäden aufgrund der ansteigenden Spannung wegen der zunehmenden Verdrillung irgendwann reißen.A device of the type mentioned is from DE-PS 44 05 776 known. Here is an electrically controllable Servomotor provided which drives a rotary disc, wherein the rotating disc the rotor of the electrically controllable Servomotor forms. The stator itself is through a support part attachable to the loom, preferably in one There is free space between the longitudinal struts and strands the first heald frames of the weaving machine. In detail here provided that the rotating disc, which the rotor of the electrically controllable servomotor forms as Guide elements two arranged opposite each other Has openings for the passage of a leno thread. This well-known rotary edge turner of a weaving machine now works in such a way that it turns several hundred revolutions in one direction and one after the other Turns a weft thread. This creates a Full turning edge. On the feeding side of the two Leno threads twist these leno threads according to the Number of revolutions of the rotating disc, so that to this To cancel the twist, a reversal of the direction of rotation is displayed is therefore the rotating disc in exactly that must rotate in the opposite direction. The number of Revolutions in each direction must average over time be equal. If the direction of rotation has not been reversed would be the leno threads due to the increasing Eventually break tension due to the increasing twist.
Bei den bekannten schnellaufenden Webmaschinen von bis zu 1200 Schuß pro Minute wurde ermittelt, daß nach einer Größenordnung von etwa 100 bis 1000 Umdrehungen in einer Richtung eine Drehrichtungsumkehr erfolgen sollte. Das heißt, daß nach dem Stand der Technik alle 10 bis 100 Sekunden der Läufer und damit die Dreherscheibe des elektrisch ansteuerbaren Stellmotors umgesteuert werden muß. Aufgrund der Hubzahl einer Webmaschine stehen hierfür maximal 100 Millisekunden (msec) zur Verfügung. Das heißt, daß innerhalb von 100 msec der Läufer des Motors stillstehen muß und wieder in voller Geschwindigkeit in die entgegengesetzten Drehrichtung rotieren muß. Dies ist aufgrund der hohen Masse der Dreherscheibe bzw. des Läufers mit bekannten Motoren nur mit hohem Aufwand zu bewerkstelligen. Hierbei könnte man natürlich auf den Gedanken kommen, die bewegte Masse des Motors dadurch zu reduzieren, daß der Motor insgesamt kleiner gewählt wird. Es besteht dann allerdings die Gefahr, daß bei einem geringeren Durchmesser des Läufers und damit der Dreherscheibe eine nur unzureichende Fachbildung zwischen den beiden durch die Dreherscheibe geführten Dreherfäden erfolgt mit dem Nachteil, daß der Schußfaden nicht sauber eingeführt werden kann. Zudem können die Fäden noch aneinander haften und mithin ist keine saubere Kante herstellbar.In the known high-speed weaving machines of up to 1200 Shot per minute was found to be of an order of magnitude from about 100 to 1000 revolutions in one direction The direction of rotation should be reversed. That means that after the State of the art every 10 to 100 seconds of runners and thus the rotating disc of the electrically controllable Actuator must be reversed. Because of the number of strokes The weaving machine has a maximum of 100 ms (msec) to disposal. That means that within 100 msec Runner of the engine must stand still and back in full Rotate the speed in the opposite direction got to. This is due to the high mass of the the runner with known motors only with great effort accomplish. Here one could of course think come to reduce the moving mass of the engine that the motor is chosen to be smaller overall. Then there is however, there is a risk that with a smaller diameter of the rotor and thus the rotating disc is an inadequate one Shed formation between the two through the rotating disc guided leno threads has the disadvantage that the Weft thread cannot be inserted cleanly. You can also the threads still stick together and therefore is not a clean one Edge can be produced.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art bereitzustellen, mit der es möglich ist, auch bei schnellaufenden Webmaschinen eine ordnungsgemäße Volldreherkante herzustellen.The invention is therefore based on the object To provide device of the type mentioned, with which is possible, even with high-speed weaving machines to produce a proper full-turn edge.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Führungselemente als Arme ausgebildet sind, die endseitig Ösen zur Durchführung der Dreherfäden aufweisen. Die Arme selbst können durchaus leicht ausgebildet werden, da sie im wesentlichen kaum beansprucht werden. Sie stellen somit eine vergleichsweise vernachlässigbare Masse dar. Durch die Anordnung von Armen an dem Rotor eines Elektromotors ist die Größe des Rotors unabhängig von dem gewünschten Öffnungswinkel des Fachs. Das heißt, es kann ein kleiner Motor mit entsprechend kleinerem Rotor gewählt werden, der dann auch eine entsprechend geringe Masse besitzt, da aufgrund der Anordnung der am Rotor angeordneten Arme der Konstrukteur nunmehr, bis auf die Leistungsanforderungen, frei in der Wahl der Größe und des Durchmessers des Motors ist. Es können deshalb auch Motoren mit geringem Durchmesser und mit entsprechend geringen bewegten Massen zum Einsatz kommen, ohne daß die Gefahr besteht, daß keine ordnungsmäße Fachöffnung bereitgestellt werden kann. Denn durch die Länge der Arme, die an dem Rotor angeordnet sind, kann der Abstand der Ösen in den Armen und damit die Größe der Fachöffnung im wesentlichen frei gewählt werden.The object is achieved in that the Guide elements are designed as arms, the ends eyelets have to carry the leno threads. The arms themselves can be easily trained as they are in can hardly be claimed. So you put one comparatively negligible mass The arrangement of arms on the rotor of an electric motor is the Size of the rotor regardless of the desired opening angle of the subject. That means it can use a small motor correspondingly smaller rotor can be selected, which then has a correspondingly low mass, because of the Arrangement of the arms of the designer arranged on the rotor now, except for the performance requirements, free to choose the size and diameter of the motor. It can therefore also motors with a small diameter and with correspondingly small moving masses are used without that there is a risk that there will be no proper opening can be provided. Because by the length of the arms that are arranged on the rotor, the distance between the eyelets in the Poor and thus the size of the compartment opening essentially free to get voted.
Nach einem vorteilhaften Merkmal der Erfindung weist der Rotor
im Bereich seiner Rotationsachse eine Bohrung zur Durchführung
der Dreherfäden auf. Das heißt, daß die Dreherfäden durch eine
zentrisch im Elektromotor angeordnete Bohrung durch diesen
hindurchführbar sind, was die Fadenführung, insbesondere im
Hinblick auf eine mögliche Verdrillung im Bereich dieser
Bohrung des Elektromotors, verbessert.
Im einzelnen ist vorgesehen, daß die Arme am auf das Gewebe
zugerichteten, stirnseitigen Ende des Rotors des Elektromotors
angeordnet sind; hierbei ist jeder Arm vorteilhaft endseitig
hakenförmig ausgebildet, wobei im Bereich der hakenförmigen
Biegung die Öse zur Führung des Dreherfadens vorgesehen ist.
Die Öse kann Einsätze aufweisen, um den Verschleiß der Öse
durch die Führung des Dreherfadens zu vermindern; denkbar sind
insbesondere hülsenförmige Einsätze aus keramischen
Werkstoffen.According to an advantageous feature of the invention, the rotor has a bore in the region of its axis of rotation for the passage of the leno threads. This means that the leno threads can be passed through a hole arranged centrally in the electric motor, which improves the thread guidance, in particular with regard to a possible twisting in the area of this hole of the electric motor.
In particular, it is provided that the arms are arranged on the end of the rotor of the electric motor facing the tissue; each arm is advantageously hook-shaped at the end, the eyelet for guiding the leno thread being provided in the region of the hook-shaped bend. The eyelet can have inserts to reduce the wear of the eyelet by guiding the leno thread; In particular, sleeve-shaped inserts made of ceramic materials are conceivable.
Nach einem weiteren Merkmal der Erfindung ist der Elektromotor mit dem Rotor derart an der Webmaschine angeordnet, daß die Rotationsachse entweder parallel oder in einem Winkel von bis zu 90° zu den Kettfäden verläuft. Insbesondere bei einer Winkelstellung von fast 90° wird die Vorrichtung in optimaler Weise unmittelbar an die Gewebekante gebracht, so daß eine Dreherkante auch unmittelbar am Gewebeende angeordnet werden kann. Hierbei kann es nach einem weiteren Merkmal der Erfindung erforderlich sein, parallel zu den am auf das Gewebe zugerichteten stirnseitigen Ende angeordneten Arme, am gegenüberliegenden stirnseitigen Ende des Rotors des Elektromotors entsprechend angeordnete weitere Arme vorzusehen. Diese weiteren Arme können deswegen erforderlich sein, um eine ordnungsgemäße Verdrillung der Dreherfäden im Bereich der Zuführung der Dreherfäden von den Spulen zu gewährleisten. Dies deshalb, damit die Verdrillung der Dreherfäden im Zuführungsbereich der Fäden von den Spulen, mit Drehrichtungsumkehr des Rotors in gleicher Weise entdrillt werden können, wie sie verdrillt wurden. Diese Problematik tritt in dieser Form nicht auf, wenn der Rotor des Elektromotors mit seiner Rotationsachse parallel zu den Kettfäden der Webmaschine angeordnet ist. According to a further feature of the invention is the electric motor arranged with the rotor on the loom such that the Rotation axis either parallel or at an angle of up to runs at 90 ° to the warp threads. Especially with one Angular position of almost 90 °, the device is optimal Brought directly to the edge of the fabric, so that a The leno edge can also be arranged directly at the end of the fabric can. Here it can be according to another characteristic of Invention may be required parallel to that on the fabric trimmed front end arms arranged on opposite end of the rotor of the Additional arms arranged correspondingly to the electric motor to provide. These additional arms may therefore be necessary to ensure proper twisting of the leno threads in the Area of supply of the leno threads from the bobbins to guarantee. This is so that the twisting of the Leno threads in the feed area of the threads from the bobbins, with Reversal of the direction of rotation of the rotor untwisted in the same way how they were twisted. This problem does not occur in this form if the rotor of the Electric motor with its axis of rotation parallel to the Warp threads of the loom is arranged.

Bei der in den Figuren 1 bis 3 dargestellten Vorrichtung 1 ist
ein insgesamt mit 10 bezeichneter Motor vorgesehen, der zur
Durchführung der Dreherfäden 20, 30 eine zentrische Bohrung 11
besitzt. Bei der in Figur 1 dargestellten Ausführungsform, bei
der die Rotationsachse quer zu den Kettfäden 40, das heißt im
wesentlichen parallel zu den Schußfäden 50 verläuft, sind zwei
Armpaare 60, 70 vorgesehen. Jedes Armpaar 60, 70 besteht aus
zwei Armen 61, 62 bzw. 71, 72. Die beiden Armpaare 60, 70
verlaufen parallel zueinander und sind am jeweils
stirnseitigen Ende des Rotors des Elektromotors 10 befestigt,
wie sich dies aus Figur 1 deutlich erkennen läßt. Die Arme 61,
62 bzw. 71, 71 sind endseitig hakenförmig gebogen ausgebildet
und weisen im Bereich der hakenförmigen Biegung die Ösen 73,
74 bzw. 63, 64 auf. Diese Ösen dienen der Durchführung der
Dreherfäden 20, 30, die von den Garnspulen 80, 90 abgezogen
werden.In the device 1 shown in Figures 1 to 3
a total of 10 designated engine provided for
Carrying the
Bei Rotation der Armpaare 60, 70 entsteht im Bereich des
Gewebes die Volldreherkante 100 (Fig.4). Im Bereich der
Zuführung der Dreherfäden 20, 30 von den Garnspulen 80, 90
erfolgt ebenfalls eine Verdrillung der Fäden (bei 110), die
dadurch wieder aufgehoben wird, daß die Drehrichtung des
Rotors nach einer bestimmten Anzahl Umdrehungen in einer
Richtung umgekehrt wird. Eine Entdrillung der Dreherkante 100
wird hierbei dadurch vermieden, daß zwischen den Dreherfäden
die Schußfäden 50 einliegen. Das heißt, daß auch bei der
Entdrillung der Verdrillungen 110 auf der anderen Seite im
Bereich des Gewebes eine weitere Gewebekante durch Verdrillung
mit den entsprechenden Schußfäden entsteht.Rotation of the arm pairs 60, 70 results in the area of the
Fabric the full-turn edge 100 (Fig. 4). In the field of
Feeding the
Die Arbeitsweise der Vorrichtung ist nun derart, daß der Rotor eines Elektromotors so angetrieben wird, daß seine Drehung mit der Schaftbewegung synchronisiert ist, so daß sich die erforderliche Fachöffnung für den Schußfadeneintrag und in Verbindung mit der Verdrehung eine Kantenabbindung ergibt. Wahlweise kann durch einen entsprechenden Phasenversatz in der Synchronisation zwischen der Drehbewegung des Rotors und der Schaftbewegung auch eine vorzeitige Abbindung erreicht werden. Das heißt eine derartige Vorrichtung arbeitet schaftunabhängig, im Gegensatz zu Kantenapparaten, die an den Webschäften eingeordnet sind.The operation of the device is now such that the rotor an electric motor is driven so that its rotation with the shaft movement is synchronized so that the required compartment opening for the weft thread entry and in Connection with the twist results in an edge binding. Optionally, a corresponding phase offset in the Synchronization between the rotary movement of the rotor and the A premature setting can also be achieved. That is, such a device works independent of the shaft, in contrast to edging devices which are attached to the Heald frames are classified.
Bei der in Figur 2 dargestellten parallel verlaufenden
Anordnung der Rotationsachse zu den Kettfäden 40, bei der die
Schäfte mit 130 und das Riet mit 140 bezeichnet sind, gibt es
naturgemäß nur geringe Probleme bei der Zuführung der
Dreherfäden 20, 30 zu der Vorrichtung. Allerdings ist bei der
in Figur 2 dargestellten Stellung des Elektromotors mit dem
Rotor zum Gewebe ein relativ großer Abstand zum Gewebe
vorhanden, so daß die Dreherkante nicht unmittelbar am Gewebe
angeordnet werden kann.In the parallel running shown in Figure 2
Arrangement of the axis of rotation to the
Wesentlich näher am Gewebe kann die Kante bei der Stellung der Vorrichtung gemäß Figur 3 angeordnet werden. Hier nämlich hat die Vorrichtung eine Stellung von etwa 45° zum Gewebe.The edge can be significantly closer to the tissue when the Device can be arranged according to Figure 3. Here namely the device has a position of approximately 45 ° to the tissue.
Allerdings ist hierbei eine Fadenführung 120 in Form einer
Rolle oder Walze vorgesehen, um die Fäden derart zum Gewebe
führen zu können, daß eine ordnungsgemäße Fachöffnung
erzeugbar ist.However, here is a
Die Bindung, die mit einer derartigen Vorrichtung herstellbar ist (Figur 4), stellt sich als sogenannte Volldreherbindung dar, das heißt, es wird durch die Bindung jeder Schußfaden vollständig abgebunden. Eine derartige Gewebekante ist trotz nur dreier Fäden äußerst stabil und weist eben aufgrund der Verwendung von nur drei Fäden eine geringe Dicke auf, so daß das Gewebe auf dem Baum im Randbereich nicht aufträgt, und somit auch nicht verläuft.The binding that can be made with such a device (Figure 4), turns out to be a so-called full twist binding dar, that is, it will bind through any weft completely tied. Such a fabric edge is despite only three threads extremely stable and just because of the Using only three threads a small thickness so that the tissue on the tree in the edge area does not apply, and thus also does not run.
