Definitions
- the invention relates to a thread guide, according to the preamble of claim 1.
- Thread guides are mainly used in the textile industry in yarn cleaners.
- a thread guide is usually arranged before and after the measuring field of the thread cleaner for thread guidance.
- State-of-the-art thread guides mostly consist of polished aluminum-ceramic discs with a V-neck (so-called V-thread guides).
- V-thread guides Common to all of them is the simultaneous limitation of the thread at three different points, which lie in a plane orthogonal to the direction of the thread. This simultaneous narrowing at three planar (in a radial plane) points results in two types of disadvantages.
- the first disadvantage is that contaminations of the thread (especially thick spots) get stuck in the planar thread narrowing;
- the second disadvantage is that the thick point causes the thread to jump out of the V-neck of the first thread guide for a short time and the thick point continues outside the measuring field without being noticed.
- the invention seeks to remedy this.
- the invention has for its object to provide a thread guide in which there is no constriction of the thread run at several points at the same time and which allows the use of a single thread guide per yarn cleaner.
- the invention solves the problem with a thread guide, which has the features of claim 1.
- a further advantage of the preferred embodiment according to the invention is that, thanks to the three spatially arranged lugs serving as thread limitation, an outlet channel asymmetrical to the running direction of the thread is produced, which can be easily cleaned at any time by means of an air nozzle attached outside the thread path.
- the thread guide shown in FIGS. 1 and 2 essentially consists of a disk-shaped base body with a front, circular base surface and a rear rectangular base surface 12.
- the base body 1 is expediently made of aluminum oxide ceramic and its surface parts are polished smooth to reduce the friction that occurs.
- the disk-shaped base body 1 has a V-shaped cutout 2 on a sector of approximately 60 °, the radii 3, 4 of which serve as the thread inlet and the center 5 of which serves as the thread guide base.
- the thread guide base 5 is designed as a first nose 6 serving to limit the thread.
- Their highest radial elevation 13 is shifted by approximately 2 mm with respect to the front base surface 11 in the direction of the rear base surface 12 of the base body 1 in order to facilitate the entry of the thread 10.
- the inlet ramp 16 of the first nose 6 facing the front base surface 11 has an angle ⁇ of 29.2 ° with respect to the central axis 17 of the base body 1.
- the right thread inlet 3 - seen in the thread running direction 9 - is designed as a second nose 7 serving to limit the thread.
- Your highest sectoral elevation 14 is shifted as far as possible in the direction of the front base 11 of the base body 1.
- the left thread inlet 4 - seen in the thread running direction 9 - is designed as a third thread 8 serving to limit the thread, the highest sectoral elevation 15 of which is shifted by approximately 2.8 mm relative to the front base surface 11 in the direction of the rear base surface 12 of the base body 1 .
- the greatest possible axial distance (of at least 1.8 mm) between the two lugs 7 and 8 is thus achieved, which counteracts the simultaneous narrowing of the thread path.
- the same purpose serves the optimal design of the inlet and outlet ramps 18, 19, 20 of the lugs 7 and 8.
- the inlet ramp 18 of the second lug 7 facing the front base 11 therefore has an angle ⁇ of 35.5 ° and that of rear base 12 facing inlet ramp 19 of the third nose 8 an angle ⁇ of 30 ° with respect to the central axis 17 of the base body 1.
- Due to the fact that the outlet ramp 20 of the second nose 7 facing the rear base surface 12 is arranged at an angle ⁇ of 52 ° with respect to the central axis 17 of the base body 1, an outlet channel 21 (FIG. 4) which runs obliquely to the central axis 17 is created which is now without difficulty can be cleaned by means of an air nozzle 22 correspondingly arranged in the extension of the outlet channel 21.
- the optimal distance of the radial or sectoral elevations 13, 14 and 15 from the base surface 11 serving as a reference surface depends on the thickness of the yarn used.
- the following typical dimensions have proven to be particularly suitable: fine yarn coarse yarn
- Thickness of the base body 1 3.5 mm 4.5 mm (Distance between front base 11 and rear base 12 measured in the direction of movement of the yarn)

Abstract
Description
Die Erfindung bezieht sich auf einen Fadenführer, gemäss dem Oberbegriff des Anspruchs 1.The invention relates to a thread guide, according to the preamble of
Fadenführer werden vor allem in der Textilindustrie in Garnreinigern verwendet. Üblicherweise werden je ein Fadenführer vor und nach dem Messfeld des Garnreinigers zur Fadenführung angeordnet.
Fadenführer gemäss dem Stand der Technik bestehen zumeist aus polierten Aluminiumkeramik-Scheiben mit einem V-Ausschnitt (sogenannte V-Fadenführer). Ihnen allen gemeinsam ist die gleichzeitige Begrenzung des Fadens an drei verschiedenen Stellen, welche in einer zur Fadenlaufrichtung orthogonalen Ebene liegen. Durch diese simultane Verengung an drei planar (in einer Radialebene) angeordneten Punkten ergeben sich zwei Arten von Nachteilen.
Der erste Nachteil besteht darin, dass Verunreinigungen des Fadens (insbesondere Dickstellen) in der planar angeordneten Fadenverengung stecken bleiben; der zweite Nachteil besteht darin, dass die Dickstelle ein kurzfristiges Herausspringen des Fadens aus dem V-Ausschnitt des ersten Fadenführers bewirkt und die Dickstelle unbemerkt ausserhalb des Messfeldes weiterläuft.Thread guides are mainly used in the textile industry in yarn cleaners. A thread guide is usually arranged before and after the measuring field of the thread cleaner for thread guidance.
State-of-the-art thread guides mostly consist of polished aluminum-ceramic discs with a V-neck (so-called V-thread guides). Common to all of them is the simultaneous limitation of the thread at three different points, which lie in a plane orthogonal to the direction of the thread. This simultaneous narrowing at three planar (in a radial plane) points results in two types of disadvantages.
The first disadvantage is that contaminations of the thread (especially thick spots) get stuck in the planar thread narrowing; the second disadvantage is that the thick point causes the thread to jump out of the V-neck of the first thread guide for a short time and the thick point continues outside the measuring field without being noticed.
Bei den immer grösseren Anforderungen, welche heute an die Präzision von Garnreinigern gestellt werden und den heute üblichen Fadengeschwindigkeiten von über 1000 m/min können die beschriebenen Nachteile immer weniger geduldet werden.With the ever increasing demands that are placed on the precision of yarn cleaners today and the thread speeds of more than 1000 m / min that are common today, the disadvantages described can be tolerated less and less.
Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aufgabe zugrunde, einen Fadenführer zu schaffen, bei dem keine Verengung des Fadenlaufes an mehreren Stellen gleichzeitig auftritt und der die Verwendung eines einzigen Fadenführers pro Garnreiniger zulässt.The invention seeks to remedy this. The invention has for its object to provide a thread guide in which there is no constriction of the thread run at several points at the same time and which allows the use of a single thread guide per yarn cleaner.
Die Erfindung löst die gestellte Aufgabe mit einem Fadenführer, welcher die Merkmale des Anspruchs 1 aufweist.The invention solves the problem with a thread guide, which has the features of
Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass dank des erfindungsgemässen Fadenführers statt mehreren (mindestens zwei) Fadenführungen nur noch eine einzige (dem Messfeld des Garnreinigers nachgeschaltete) benötigt wird und auch grosse Fehler im geführten Faden nicht im Messfeld stecken bleiben oder um dieses geführt werden.The advantages achieved by the invention are essentially to be seen in the fact that, thanks to the thread guide according to the invention, instead of several (at least two) thread guides, only a single one (downstream of the measuring field of the yarn cleaner) is required and even large errors in the guided thread do not get stuck in the measuring field or be led around this.
Ein weiterer Vorteil der bevorzugten, erfindungsgemässen Ausführungsform besteht darin, dass dank der drei als Fadenbegrenzung dienenden, räumlich angeordneten Nasen ein zur Laufrichtung des Fadens asymmetrischer Austrittskanal erzeugt wird, der leicht mittels einer ausserhalb des Fadenweges angebrachten Luftdüse jederzeit gereinigt werden kann.A further advantage of the preferred embodiment according to the invention is that, thanks to the three spatially arranged lugs serving as thread limitation, an outlet channel asymmetrical to the running direction of the thread is produced, which can be easily cleaned at any time by means of an air nozzle attached outside the thread path.
Ein Ausführungsbeispiel der Erfindung, welches zugleich das Funktionsprinzip erläutert, ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.
- Fig. 1 stellt eine perspektivische Ansicht des Fadenfuhrers von hinten dar;
- Fig. 2 stellt eine axiale Ansicht des Fadenführer von hinten dar;
- Fig. 3 stellt einen radialen Längsschnitt im Bereich des V-Ausschnitts des Fadenführers dar; und
- Fig. 4 stellt einen zur Fig. 3 senkrechten Querschnitt durch den Fadenführer dar.
- Fig. 1 shows a perspective view of the thread guide from behind;
- Fig. 2 shows an axial view of the thread guide from the rear;
- 3 shows a radial longitudinal section in the area of the V-section of the thread guide; and
- Fig. 4 shows a cross section perpendicular to Fig. 3 through the thread guide.
Der in den Fig. 1 und 2 dargestellte Fadenführer besteht im wesentlichen aus einem scheibenförmigen Grundkörper mit einer vorderen, kreisförmigen Grundfläche und einer hinteren rechteckförmigen Grundfläche 12. Der Grundkörper 1 wird zweckmässigerweise aus Aluminiumoxidkeramik gefertigt und seine Oberflächenpartien zwecks Verminderung der auftretenden Reibung glatt poliert. Der scheibenförmige Grundkörper 1 weist auf einem Sektor von etwa 60° einen V-förmigen Ausschnitt 2 auf, dessen Radien 3,4 als Fadeneinlauf und dessen Zentrum 5 als Fadenführergrund dienen.The thread guide shown in FIGS. 1 and 2 essentially consists of a disk-shaped base body with a front, circular base surface and a rear
Wie aus Fig. 3 ersichtlich, ist der Fadenführergrund 5 als eine erste der Fadenbegrenzung dienende Nase 6 ausgebildet. Ihre höchste radiale Erhebung 13 ist gegenüber der vorderen Grundfläche 11 in Richtung der hinteren Grundfläche 12 des Grundkörpers 1 um ca. 2 mm verschoben, um den Einlauf des Fadens 10 zu erleichtern. Aus dem gleichen Grunde weist die der vorderen Grundfläche 11 zugewandte Einlaufsrampe 16 der ersten Nase 6 einen Winkel α von 29,2° gegenüber der Zentralachse 17 des Grundkörpers 1 auf.3, the
Wie aus Fig. 4 ersichtlich, ist der - in Fadenlaufrichtung 9 gesehene - rechte Fadeneinlauf 3 als eine zweite der Fadenbegrenzung dienende Nase 7 ausgebildet. Ihre höchste sektorielle Erhebung 14 ist soweit als möglich in Richtung der vorderen Grundfläche 11 des Grundkörpers 1 verschoben. Ebenso ist der - in Fadenlaufrichtung 9 gesehene - linke Fadeneinlauf 4 als eine dritte der Fadenbegrenzung dienende Nase 8 ausgebildet, deren höchste sektorielle Erhebung 15 gegenüber der vorderen Grundfläche 11 in Richtung der hinteren Grundfläche 12 des Grundkörpers 1 um ca. 2,8 mm verschoben ist. Damit wird ein möglichst grosser axialer Abstand (von mindestens 1,8 mm) der beiden Nasen 7 und 8 erzielt, was der gleichzeitigen Verengung des Fadenlaufs entgegenwirkt.As can be seen from FIG. 4, the right thread inlet 3 - seen in the thread running direction 9 - is designed as a
Dem gleichen Zweck dient die optimale Gestaltung der Ein- und Auslaufsrampen 18,19,20 der Nasen 7 und 8. Die der vorderen Grundfläche 11 zugewandte Einlaufsrampe 18 der zweiten Nase 7 weist aus diesem Grunde einen Winkel ß von 35,5° und die der hinteren Grundfläche 12 zugewandte Einlaufsrampe 19 der dritten Nase 8 einen Winkel δ von 30° gegenüber der Zentralachse 17 des Grundkörpers 1 auf.
Dadurch, dass die der hinteren Grundfläche 12 zugewandte Auslaufsrampe 20 der zweiten Nase 7 mit einem Winkel σ von 52° gegenüber der Zentralachse 17 des Grundkörpers 1 angeordnet ist, entsteht ein schräg zur Zentralachse 17 verlaufender Austrittskanal 21 (Fig. 4) der nun ohne Schwierigkeiten mittels einer entsprechend in der Verlängerung des Austrittskanals 21 angeordneten Luftdüse 22 gereinigt werden kann.The same purpose serves the optimal design of the inlet and
Due to the fact that the outlet ramp 20 of the
Der optimale Abstand der radialen, bzw. sektoriellen Erhebungen 13,14 und 15 von der als Bezugsfläche dienenden Grundfläche 11 hängt von der Stärke des verwendeten Garnes ab.
Folgende, typische Dimensionen haben sich als besonders geeignet erwiesen:
The following typical dimensions have proven to be particularly suitable:
