Abstract

A single sleeve for the simultaneous winding/unwinding of several monofilaments (3, 3') consists of a cylindrical sleeve (1) secured to a cone (2). The process makes it possible during winding or unwinding to wind and unwind several monofilaments with a count of between 10 and 100 dtex on a cone (2) at a winding speed of at least 100 m/min. The multi-way yarn support of the invention makes it possible considerably to increase productivity in the production of monofilaments in the fine and medium count range.

Description

Einfachhülse zum gleichzeitigen Aufspulen/Abspulen von mehreren onofilamenten und Verfahren zum Single sleeve for simultaneous winding / unwinding of several onofilaments and process for
Aufspulen/Abspulen derselben.Winding / unwinding the same.
Die Erfindung betrifft eine Einfachkonushülse aus Metall zum gleichzeitigen mehrendigen Aufspulen/Ab-spulen von mehreren thermoplastischen Monofilamenten, mit einem Titer von 10-100 dtex, bestehend aus einer zylindrischen Hülse und einem Konus, der unmittelbar mit der Hülse verbunden ist, sowie einem Verfahren zum Aufspulen/Abspulen derselben.The invention relates to a single cone sleeve made of metal for simultaneous multi-end winding / unwinding of several thermoplastic monofilaments, with a titer of 10-100 dtex, consisting of a cylindrical sleeve and a cone, which is connected directly to the sleeve, and a method for Winding / unwinding the same.
Unter dem Begriff Monofilamente ist ein thermoplastischer Faden zu verstehen, der aus einer einzelnen endlosen Fibrille besteht, deren Oberfläche praktisch glatt und deren Durchmesser gleichmässig ist. Da beim Auf- und Abspulen solcher Monofilamente die Gefahr des Verrutschens oder Abrutschens einzelner Monofile und des Verschiebens der Fadenlagen gross ist, werden als Garnträger unter anderem bikonische Randspulen in Form von Kombinationshülsen verwendet.The term monofilaments is to be understood as a thermoplastic thread which consists of a single endless fibril, the surface of which is practically smooth and the diameter of which is uniform. As the risk of slipping or slipping off of individual monofilaments and shifting of the thread layers is great when winding and unwinding such monofilaments, biconical edge bobbins in the form of combination sleeves are used as the yarn carrier.
Kombinationshülsen für eine konische Aufmachung sind bekannt (EP-0 180 300). Dabei ist die Hülse über ihre gesamte Länge konisch oder als Kombihülse für eine sogenannte Diabolo-Aufmachung ausgebildet. Eine Fadenreserve ist dabei an der Stelle des kleinsten Durchmessers vorgesehen. Solche Hülsen ermöglichen das Auf- und Abspulen eines Fadens. Dabei sind besondere Vorsichtsmassnahmen zu treffen, um das gleichmässige Ablegen und Verrutschen zu vermeiden. Das gleichzeitige Aufspulen oder Abspulen mehrerer Monofile ist mit den bekannten Garnträgern der Art jedoch nicht möglich.Combination sleeves for a conical presentation are known (EP-0 180 300). The sleeve is conical over its entire length or as a combination sleeve for a so-called diabolo presentation. A thread reserve is provided at the point of the smallest diameter. Such sleeves make it possible Winding and unwinding a thread. Special precautionary measures must be taken in order to avoid even laying down and slipping. However, simultaneous winding or unwinding of several monofilaments is not possible with the known yarn carriers of the type.
Ein einseitig konischer Spulenkörper ist auch aus der US-A-2, 624, 525 bekannt. Dieser Spulenkörper ist aus Papier hergestellt. Im Bereich der Fadenablage auf dem wenig geneigten konischen Teil des Garnträgers ist eine verklebte Fadenauflage angebracht, auf welche ein textiler multifiler Faden aufgewickelt werden kann. Zum mehrendigen Ablegen und Abspulen von Monofilamenten mit glatter Oberfläche sind solche Garnträger ungeeignet. Einerseits können bei einem solchen Garnträger die auf den zylindrischen Teil wirkenden Kräfte nicht aufgenommen werden und andererseits ist ein Betrieb bei hohen Spulgeschwindigkeiten wegen auftretender Unwucht unmöglich. Solche Garnträger erlauben lediglich die Ablage eines Fadens. Zudem ist eine Produktivitätserhöhung über die Spinngeschwindigkeit mit den bekannten Garnträgern sehr limitiert.A coil body which is conical on one side is also known from US Pat. No. 2,624,525. This bobbin is made of paper. In the area of the thread deposit on the slightly inclined conical part of the thread carrier, a glued thread support is attached, on which a textile multifilament thread can be wound. Such yarn carriers are unsuitable for multiple-end laying and unwinding of monofilaments with a smooth surface. On the one hand, the forces acting on the cylindrical part cannot be absorbed with such a yarn carrier, and on the other hand, operation at high winding speeds is impossible due to imbalance. Such yarn carriers only allow the filing of a thread. In addition, an increase in productivity via the spinning speed with the known yarn carriers is very limited.
Aufgabe der Erfindung ist es eine Einfachhülse für Monofilamente zur Verfügung zu stellen, auf welcher gleichzeitig mehrere Monofilamente aufgespult und für dieThe object of the invention is to provide a single sleeve for monofilaments, on which several monofilaments are simultaneously wound and for which
Kettherstellung mehrendig wieder abgespult werden können.Warp production can be rewound at multiple ends.
Eine weitere Aufgabe ist es ein Verfahren so zu gestalten, dass mehrere Monofilamente mehrendig aufgespult und anschliessend mehrendig wieder abgespult werden können, um dadurch die Wirtschaftlichkeit der Herstellung der Monofilamente pro Spulstelle wesentlich zu verbessern.Another object is to design a method in such a way that a plurality of monofilaments can be spooled on several ends and then rewound on several ends in order to significantly improve the cost-effectiveness of producing the monofilaments per winding point.
Eine weitere Aufgabe ist die Erhöhung der Produktivität bei der Herstellung von Monofililamenten im interessierenden Titerbereich durch Erhöhung der abgelegten Garnmenge bis etwa 40 kg pro Spule.Another task is to increase productivity in the manufacture of monofilaments in the titer range of interest by increasing the amount of yarn deposited up to about 40 kg per bobbin.
Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass der Steigungswinkel α des Konus zur Hülse > 15-35 Grad beträgt, und die Oberfläche des Konus gegenüber dem Faden abriebfest ist. Der Vorteil wird darin gesehen, dass eine Vielzahl von Monofilamenten auf eine einzige Einfachhülse gleichzeitig nebeneinander abgelegt und bei Bedarf wieder abgespult werden können. Es fallen viele personalintensive Wechselvorgänge weg. Es ist eine zusätzliche Produktivitätserhöhung aufgrund der Erhöhung der Aufspulgeschwindigkeit bis auf 3000 m/min, etwa das Zehnfache der bekannten Spulgeschwindigkeiten, möglich. Ein weiterer Vorteil kann in dem enorm geringeren Raumbedarf den eine einzige Einfachhülse anstelle einer Vielzahl von Garnträgern und damit auch Spulern benötigt, gesehen werden.The object is achieved according to the invention in that the pitch angle α of the cone to the sleeve is> 15-35 degrees and the surface of the cone is abrasion-resistant with respect to the thread. The advantage is seen in the fact that a large number of monofilaments can be placed on a single single sleeve at the same time side by side and can be unwound again if necessary. Many personnel-intensive change processes are eliminated. An additional increase in productivity is possible due to the increase in the winding speed up to 3000 m / min, approximately ten times the known winding speeds. Another advantage can be seen in the enormously reduced space required by a single single tube instead of a large number of thread carriers and thus also spools.
Es ist zweckmässig dass der Konus und die Hülse starr und übergangslos miteinander verbunden sind. Das hat den Vorteil, dass die inneren Lagen der Monofilamente nicht verklemmen und vollständig abgearbeitet werden können.It is expedient that the cone and the sleeve are rigidly and seamlessly connected to one another. This has the advantage that the inner layers of the monofilaments cannot get jammed and can be processed completely.
Der Steigungswinkel α des Konus zur Hülse soll < 15 bis 35 Grad, insbesondere 20 bis 30 Grad, bevorzugt 25 bis 30 Grad betragen. Ein Steigungswinkel kleiner als 15 Grad ist nicht ausreichend, da bei gegebener Ablegbreite pro Monofil und gegenüber der Hülsenlänge die Anzahl der ablegbaren Monofile verringert und damit die Wirtschaftlichkeit verschlechtert wird; ist der Steigungswinkel grösser als 35 Grad ist die Stabilität der Wicklung nicht mehr gegeben.The pitch angle α of the cone to the sleeve should be <15 to 35 degrees, in particular 20 to 30 degrees, preferably 25 to 30 degrees. A pitch angle of less than 15 degrees is not sufficient, since for a given filing width per monofilament and compared to the length of the sleeve, the number of monofilaments that can be deposited is reduced and thus the economy is impaired; If the pitch angle is greater than 35 degrees, the winding is no longer stable.
Die Oberfläche des Konus ist gegenüber dem Faden abriebfest. Härte zu spezifizieren ist in diesem Fall nicht sinnvoll, da die geeignete Oberfläche eine Kunststoffbeschichtung sein oder metallisiert sein kann. Bewährt hat sich eine Beschichtung durch Eloxierung oder Verchromung. Als Material für die Einfachhülse sind Metalle wie Stahl und Leichtmetalle wie Aluminium am besten geeignet.The surface of the cone is resistant to abrasion against the thread. Specifying hardness in this case does not make sense, since the suitable surface is a Be plastic coating or metallized. A coating by anodizing or chrome plating has proven itself. Metals such as steel and light metals such as aluminum are the most suitable materials for the single sleeve.
Beim Verfahren zum gleichzeitigen Aufspulen oder Abspulen von wenigstens 2 Monofilamenten mit einem Titer von dtex 10-100 dtex auf einen Garnträger werden die Monofilamente konisch, parallel zum Konus mit einer Aufspulgeschwindigkeit von wenigstens 100 m/min, bevorzugt wenigsten 600 bis 3000 m/min abgelegt und in den gleichen Geschwindigkeitsbereichen abgespult. Der bevorzugte Titerbereich der Monofilamente liegt zwischen 10 bis 100 dtex. Das Verfahren erlaubt das gemeinsame Abarbeiten der Monofilamente, aber auch die Abarbeitung einzelner Monofilamente.In the process for simultaneous winding or unwinding of at least 2 monofilaments with a titer of dtex 10-100 dtex onto a yarn carrier, the monofilaments are laid down conically, parallel to the cone, at a winding speed of at least 100 m / min, preferably at least 600 to 3000 m / min and unwound in the same speed ranges. The preferred titer range of the monofilaments is between 10 and 100 dtex. The method allows the monofilaments to be processed together, but also the processing of individual monofilaments.
Die Erfindung soll anhand von Zeichnungen näher beschrieben werden.The invention will be described in more detail with reference to drawings.

In Fig. 1 ist mit dem Bezugszeichen 1 eine metallische zylindrische Hülse der erfindungsgemässen Einfachhülse bezeichnet. Die Hülse 1 geht unmittelbar in einen Konus 2 über. Die Hülse 1 bildet mit dem Konus 2 einen Winkel α. Die Oberfläche der Einfachhülse ist so behandelt, dass sie gegenüber thermoplastischen Monofilen abriebfest ist.In Fig. 1, the reference numeral 1 denotes a metallic cylindrical sleeve of the single sleeve according to the invention. The sleeve 1 merges directly into a cone 2. The sleeve 1 forms an angle α with the cone 2. The surface of the single sleeve is treated so that it is resistant to abrasion compared to thermoplastic monofilaments.
In der schematischen Fig. 2 ist auf die Hülse 1 mit dem Konus 2 eine Schar von einzelnen Monofilamenten 3,3' aufgebracht, wobei nur die innerste Monofilamentlage bis zu einer mittleren Monofilamentlage bezeichnet ist.In the schematic FIG. 2, a group of individual monofilaments 3, 3 'is on the sleeve 1 with the cone 2 applied, whereby only the innermost monofilament layer is designated up to a middle monofilament layer.
Im Betrieb werden die ersten Lagen der Monofilamente 3 bis 3' gleichzeitig auf die Hülse 1 aufgebracht, wobei die Breite der einzelnen Lagen, beispielsweise 20 mm, durch die Changierfadenführer in bekannter Weise festgelegt sind. Mit zunehmenden Lagen wandern diese auf den Konus 2, bis die gewünschten Dicken der Lagen erreicht sind.In operation, the first layers of monofilaments 3 to 3 'are simultaneously applied to the sleeve 1, the width of the individual layers, for example 20 mm, being fixed in a known manner by the traversing thread guides. With increasing layers, these migrate onto cone 2 until the desired thicknesses of the layers are reached.
Für den Ablauf der Monofilamente sind zwei Varianten, der Parallelablauf und der Ablauf "über Kopf" möglich. Beim Parallelablauf wird die bewickelte Einfachhülse mit einer gewählten Drehzahl gedreht und die Monofilamente 3,3' mit einer definierten Geschwindigkeit abgezogen und einer Weiterverarbeitung zugeführt. Die Fadenspannung wird konstant gehalten. Beim Ablauf "über Kopf" erfolgt in analoger Weise bei einer definierten Geschwindigkeit und konstanter Fadenspannung oder frei durch Ballonbildung.Two variants are possible for the drainage of the monofilaments, the parallel drainage and the "overhead" drainage. In the parallel process, the wound single tube is rotated at a selected speed and the monofilaments 3, 3 'are drawn off at a defined speed and fed to further processing. The thread tension is kept constant. In the "overhead" process, this takes place in an analogous manner at a defined speed and constant thread tension or freely by balloon formation.
Die erfindungsgemässe Einfachhülse ist mehrfach verwendbar. Mit dem erfindungsgemässen Mehrfachgarnträger kann die Produktivität der Herstellung von Monofilen im feinen und mittleren Titerbereich erheblich gesteigert werden. Der Garnträger ist ohne Verrutschen der Monofillagen transportierbar und in der Weberei für Kette und Schuss einsetzbar. The single sleeve according to the invention can be used several times. With the multiple yarn carrier according to the invention, the productivity of the production of monofilaments in the fine and medium titer range can be increased considerably. The thread carrier can be transported without slipping the monofilament layers and can be used in the weaving mill for warp and weft.
