Zum Anlegen einer Fadenreserve und zur Wicklung wird der Aufnahmering (4) aus einer ersten Position (B) über den Rand des Garnträgers hinaus verschoben; zum Transport und zur Lagerung der Spule wird der Aufnahmering (4) teilweise in die Hülse (1) soweit eingeschoben, dass er über die Peripherie der Stirnseite (2) hinausragt. Der erfindungsgemässe Garnträger ist besonders zum Aufwickeln von Monofilen mit hohen Geschwindigkeiten geeignet.A coaxially displaceable receiving ring (4) is arranged on a biconical yarn carrier on the end face (3). To create a thread reserve and for winding, the receiving ring (4) is moved from a first position (B) beyond the edge of the yarn carrier; for transport and storage of the coil, the receiving ring (4) is partially inserted into the sleeve (1) to such an extent that it projects beyond the periphery of the end face (2). The yarn carrier according to the invention is particularly suitable for winding monofilaments at high speeds.

Description

Die Erfindung betrifft einen Garnträger zum Aufspulen eines Filamentfadens, bestehend aus einer zylindrischen Hülse mit konischen Stirnseiten und ein Verfahren zur Bildung einer Fa­denreserve.The invention relates to a yarn carrier for winding a filament thread, consisting of a cylindrical sleeve with conical end faces, and a method for forming a thread reserve.

Garnträger, die im wesentlichen aus einem zylindrischen star­ren Rohrkörper und konischen Endteilen aus Kunststoff beste­hen, sind als Aufspulhülsen bekannt (CH 569 662). Solche Garnträger können auch als bikonische Spulen bezeichnet wer­den und unterscheiden sich von den symmetrischen Randspulen dadurch, dass ihre Stirnseiten gegen die Peripherie hin einen vergrösserten Durchmesser annehmen. Bikonische Randspulen ha­ben sich zum Aufwickeln von Monofilamentfäden mittlerer Dicke (ca. ⌀ 0,05 bis ⌀ 0,3 mm) bewährt, haben aber den Nachteil, dass die für eine problemlose Weiterverarbeitung der Monofi­lamentfäden erforderliche Fadenreserve nicht vorgesehen ist. Die Fadenreserve ist jedoch unentbehrlich beim automatischen Wechseln eines Fadens von einer leer gewordenen auf eine vol­le Spule. Ohne eine Fadenreserve an der konischen Spule tre­ten in der Weberei Unterbrüche auf.Yarn carriers which essentially consist of a cylindrical rigid tubular body and conical end parts made of plastic are known as winding tubes (CH 569 662). Such yarn carriers can also be referred to as biconical bobbins and differ from the symmetrical edge bobbins in that their end faces assume an enlarged diameter towards the periphery. Biconical edge bobbins have proven themselves for winding monofilament threads of medium thickness (approx. ⌀ 0.05 to ⌀ 0.3 mm), but have the disadvantage that the thread reserve required for easy further processing of the monofilament threads is not provided. However, the thread reserve is indispensable when automatically changing a thread from an empty to a full bobbin. Without a thread reserve on the conical bobbin, interruptions occur in the weaving mill.

Aufgabe der Erfindung ist es, eine bikonische Spule so zu ge­stalten, dass die Aufnahme einer Fadenreserve erfolgen kann.The object of the invention is to design a biconical bobbin in such a way that a thread reserve can be taken up.

Eine weitere Aufgabe ist es, den Garnträger so auszubilden, dass beim Transport der Faden der Fadenreserve nicht beschä­digt wird.Another task is to design the thread carrier in such a way that the thread reserve is not damaged during the transport of the thread.

Eine weitere Aufgabe ist es auch, die Fadenreserve der vollen Spule einfach und rasch nutzbar zu machen.Another task is to make the thread reserve of the full bobbin easy and quick to use.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass ein Aufnahmering an der Stirnseite koaxial verschiebbar angeord­net ist.According to the invention, the object is achieved in that a receiving ring is arranged on the end face so as to be coaxially displaceable.

Garnträger und Aufnahmering bestehen vorzugsweise aus einem stabilen Kunststoff. Sie können aber auch aus einem anderen dauerhaften Werkstoff gefertigt sein.The thread carrier and receiving ring are preferably made of a stable plastic. But they can also be made of another durable material.

Es ist zweckmässig, dass der Durchmesser der Hülse von dem­jenigen des Aufnahmerings nicht wesentlich abweicht, da die Umfangsgeschwindigkeit der Fadenreserve annähernd gleich sein muss wie diejenige des Wickels zu Beginn der Wicklung. Es ist daher vorteilhaft, wenn beide Durchmesser annähernd gleich sind.It is expedient that the diameter of the sleeve does not deviate significantly from that of the receiving ring, since the peripheral speed of the thread reserve must be approximately the same as that of the winding at the start of the winding. It is therefore advantageous if both diameters are approximately the same.

Es ist auch zweckmässig, die Innenseite der Hülse mit wenig­stens zwei Ringnuten zu versehen, in welche ein Ringnocken des Aufnahmeringes einrastend passt.It is also expedient to provide the inside of the sleeve with at least two ring grooves, in which a ring cam of the receiving ring fits snugly.

Aussparungen zwischen den Profilen des Aufnahmeringes haben einerseits den Vorteil, dass das Gewicht reduziert ist und andererseits, dass die Fadenreste auf einfache Weise mit einer Schere entfernbar sind. Durch die axial verlaufenden Profile erhält der Ring die gewünschte Elastizität, wodurch er erst problemlos in die Hülse eingeschoben und ebenso leicht wieder daraus entfernt werden kann.Recesses between the profiles of the receiving ring have the advantage on the one hand that the weight is reduced and on the other hand that the thread remnants can be easily removed with scissors. The axially extending profiles give the ring the desired elasticity, which means that it can only be easily inserted into the sleeve and just as easily removed from it.

Es ist zweckmässig, die Peripherie des Aufnahmeringes mit we­nigstens einem Schlitz zu versehen. Ein in etwa tangential in Drehrichtung verlaufender Fangschlitz hat den Vorteil, dass auch bei hohen Umfangsgeschwindigkeiten der Hülse ein siche­res Fangen des Fadens gewährleistet ist.It is expedient to provide the periphery of the receiving ring with at least one slot. A catch slot running approximately tangentially in the direction of rotation has the advantage that a safe catching of the thread is ensured even at high peripheral speeds of the sleeve.

In einer bevorzugten Ausführungsform ragt der Aufnahmering im eingeschobenen Zustand wenigstens 1 mm über den Spulenrand, d.h. über die Peripherie der Stirnseite hinaus. Das hat den Vorteil, dass beim Transport und der Lagerung der Faden im Bereich des Hülsenrandes nicht verquetscht oder anderweitig beschädigt wird.In a preferred embodiment, the receiving ring in the inserted state protrudes at least 1 mm beyond the edge of the coil, ie beyond the periphery of the end face. This has the advantage that the thread is transported and stored in the Area of the sleeve edge is not crushed or otherwise damaged.

In einer weiteren Ausführungsform kann die Peripherie gezähnt sein. Hier kann ein Faden der Fadenreserve in den Vertie­fungen zwischen den Zähnen Halt finden und während des Trans­portes oder der Lagerung nicht zwischen einem Gegenstand und dem Spulenrand beschädigt werden. Die Zähne können spitz oder abgerundet sein.In a further embodiment, the periphery can be serrated. Here a thread of the thread reserve can find a hold in the recesses between the teeth and cannot be damaged between an object and the edge of the spool during transport or storage. The teeth can be pointed or rounded.

Zur Bildung einer Fadenreserve kann der Aufnahmering an sei­ner Oberfläche aufgerauht sein und ist in einer ersten Posi­tion über den Spulenrand hinaus ausgefahren. Nach dem Auf­bringen der Fadenreserve erfolgt die Wicklung. Der Aufnahme­ring wird nach Wegnahme und zum Transport in eine zweite Po­sition eingeschoben. Zur Wegnahme der Fadenreservewindung wird der Aufnahmering wieder in die erste Position gezogen und durch eine Drehbewegung die Spannung des ablaufenden Fadens gelöst.To form a thread reserve, the receiving ring can be roughened on its surface and is extended in a first position beyond the edge of the spool. After the thread reserve has been applied, the winding takes place. The receiving ring is pushed into a second position after removal and for transport. To remove the thread reserve winding, the take-up ring is pulled back into the first position and the tension of the thread running off is released by a rotary movement.

Die Erfindung soll anhand einer Zeichnung beispielhaft erläu­tert werden.The invention will be explained by way of example with reference to a drawing.

In Fig. 1 ist eine zylindrische Hülse einer bikonischen Spule mit der Bezugsziffer 1 bezeichnet. Die Hülse 1 ist von einer konischen Stirnseite 2 und einer konischen Stirnseite 3 be­grenzt. Die Hülse 1 mit den Stirnseiten 2 und 3 können aus einem Teil gefertigt sein. Im Innern des Konus der Stirnseite 3 ist ein Aufnahmering 4 angebracht. Im ausgezogenen Zustand nimmt der Aussenrand des Aufnahmeringes 4 eine Position A ein. Der eingeschobene Aufnahmering 4 ist gestrichelt ge­zeichnet. Der Aussenrand des Aufnahmeringes 4 nimmt hier die Position B ein.In Fig. 1, a cylindrical sleeve of a biconical coil is designated by the reference number 1. The sleeve 1 is delimited by a conical end face 2 and a conical end face 3. The sleeve 1 with the end faces 2 and 3 can be made from one part. A receiving ring 4 is fitted inside the cone of the end face 3. In the extended state the outer edge of the receiving ring 4 assumes a position A. The inserted receiving ring 4 is drawn in dashed lines. The outer edge of the receiving ring 4 takes the position B here.

Gemäss Fig. 2 ist mit 4ʹ die zylindrische Oberfläche des Auf­nahmeringes 4 bezeichnet. Die Hülse 1 ist auf ihrer Innensei­te mit wenigstens zwei parallel verlaufenden Ringnuten verse­hen. Eine innere Ringnut 6 verläuft in einem Abstand AB zu einer äusseren Ringnut 5. Der Aufnahmering 4 trägt auf seiner Innenseite einen Ringnocken 7. Die Lage des Ringnockens 7 ist so vorgesehen, dass dieser beim Einschub des Aufnahmeringes 4 in die Hülse 1 in der inneren Ringnut 5 einrastet. Der Ab­stand AB ist so gewählt, dass die axiale Verschiebbarkeit des Aufnahmeringes 4 beim Einrasten der Ringnocke 7 in die Ring­nut 5 eine saubere Wicklung mit einer Fadenreserve ermög­licht.2, 4ʹ denotes the cylindrical surface of the receiving ring 4. The sleeve 1 is provided on its inside with at least two parallel ring grooves. An inner annular groove 6 runs at a distance AB from an outer annular groove 5. The receiving ring 4 carries an annular cam 7 on its inside. The position of the annular cam 7 is provided in such a way that when the receiving ring 4 is inserted into the sleeve 1 in the inner annular groove 5 clicks into place. The distance AB is selected so that the axial displaceability of the receiving ring 4 when the ring cam 7 engages in the ring groove 5 enables a clean winding with a thread reserve.

In Fig. 3 ist der Aufnahmering 4 mit Profilen 8 versehen, welche elastisch gestaltet sind, so dass der Einschub in die Hülse 1 sicher und rasch erfolgen kann.In Fig. 3, the receiving ring 4 is provided with profiles 8, which are designed to be elastic, so that the insertion into the sleeve 1 can be done safely and quickly.

In Fig. 4 ist die Peripherie des Aufnahmeringes 4 mit einem Schlitz 9 dargestellt. Der Schlitz 9 dient in Pfeilrichtung als Fadenfang.4 shows the periphery of the receiving ring 4 with a slot 9. The slot 9 serves as a thread catch in the direction of the arrow.

Im Betrieb wird der Garnträger mit aus der Hülse 1 herausge­zogenem Aufnahmering 4 auf den Dorn eines nicht gezeigten Spulers aufgesteckt und beschleunigt. Nach dem Erreichen der Solldrehzal wird der Faden von einer vollen Spule so geführt, dass der Faden vom Schlitz 9 und der rauhen Oberfläche 4ʹ des Aufnahmeringes der leeren Hülse 1 erfasst wird und die Faden­reserve an den Aufnahmering 4 angelegt wird, was etwa 0,8 bis 1,2 s dauert. Unmittelbar danach wird die Hülse 1 bewickelt. Die volle Spule wird vom Dorn abgenommen und der Aufnahmering 4 in die Position B zum Transport und zur Lagerung von Hand oder maschinell eingeschoben.In operation, the yarn carrier with the receiving ring 4 pulled out of the sleeve 1 is placed on the mandrel of a winder, not shown, and accelerated. After reaching the target speed, the thread is guided by a full bobbin so that the thread is gripped by the slot 9 and the rough surface 4ʹ of the receiving ring of the empty sleeve 1 and the thread reserve is applied to the receiving ring 4, which is about 0.8 to Lasts 1.2 s. Immediately afterwards, the sleeve 1 is wound. The full spool is removed from the mandrel and the receiving ring 4 is pushed into position B for transport and storage by hand or by machine.

Es können auf dem Dorn eines Spulers mehrere Wickelträger vorgesehen werden. Der erfindungsgemässe Wickelträger ist be­sonders zum Aufwickeln von schnellaufenden Monofilamentfäden im Titerbereich von ⌀ 0,05 bis ⌀ 0,3 mm geeignet und hat sich auch bei hohen Geschwindigkeiten verstreckter Fäden zum auto­matischen Wechseln von einer leeren Spule auf eine volle Spu­le bewährt.Several winding carriers can be provided on the mandrel of a winder. The winding support according to the invention is particularly suitable for winding high-speed monofilament threads in the titer range from ⌀ 0.05 to ⌀ 0.3 mm and has also proven itself at high speeds of stretched threads for automatically changing from an empty bobbin to a full bobbin.
