Description

Technisches Gebiettechnical field

Die Erfindung bezieht sich auf eine Ringspinnmaschine und ein Verfahren zum Betrieb einer Ringspinnmaschine entsprechend dem jeweiligen Oberbegriff der unabhängigen Ansprüche.The invention relates to a ring spinning machine and a method for operating a ring spinning machine according to the respective preamble of the independent claims.

Stand der TechnikState of the art

Ringspinnmaschinen mit Changiervorrichtung zur Vorgarnverlegung sind an sich bereits bekannt. Bei der Zuführung des Vorgarns zum Streckwerk wird durch die Vorgarnverlegung erreicht, dass die Abnutzung der Streckwerkswalzen, die durch ein gleichmässiges Zuführen des Vorgarns an einer Stelle entstehen würde, reduziert wird. Die Abnutzung der Walzen wird vielmehr durch eine Verlegung der Zuführung auf einen bestimmten, definierten Bereich verteilt. Die Changiervorrichtung ist zu diesem Zweck mit Vorgarnleitschienen verbunden, die das Vorgarn dem Streckwerk bewegt zuführen.Ring spinning machines with a traversing device for roving laying are already known per se. When the roving is fed to the drafting system, laying the roving reduces the wear on the drafting system rollers that would occur if the roving were evenly fed in at one point. Instead, the wear on the rollers is distributed over a specific, defined area by moving the feed. For this purpose, the traversing device is connected to roving guide rails, which move the roving to the drafting system.

DE112012005348T5 offenbart eine Spinnmaschine mit einer Mehrzahl von Spinnstellen mit jeweils einem Streckwerk und einem Zwischenantrieb. Ein Streckwerk weist wenigstens zwei Verzugswalzen auf, die mit Druckwalzen gekoppelt sind. Der Zwischenantrieb ist zwischen den Längsenden der Verzugswalzen angeordnet, wodurch die auf beiden Seiten des Zwischenantriebs vorhandenen Sektionen der Verzugswalzen über den Zwischenantrieb antreibbar sind. Die Spinnmaschine weist eine vom Zwischenantrieb angetriebene Oszillationsvorrichtung zum Bewegen des Vorgarns in Längsrichtung der Maschine auf, wobei die Vorrichtung Garnführungsstangen umfasst, die sich von beiden Seiten des Zwischenantriebs aus erstrecken. Die Oszillationsvorrichtung von einem Zwischenantrieb anzutreiben hat sich allerdings als wenig vorteilhaft erwiesen, da man an den Zwischenantrieb gebunden ist und man sich dementsprechend konstruktiv einschränkt. Bei längeren Maschinen kann es beispielsweise notwendig sein, mehrere Changiervorrichtungen einzusetzen. Dies ist aber in DE112012005348T5 gar nicht möglich. DE112012005348T5 discloses a spinning machine with a plurality of spinning positions, each with a drafting system and an intermediate drive. A drafting system has at least two drafting rollers which are coupled to pressure rollers. The intermediate drive is arranged between the longitudinal ends of the drafting rollers, as a result of which the sections of the drafting rollers present on both sides of the intermediate drive can be driven via the intermediate drive. The spinning machine has an oscillating device driven by the intermediate drive for moving the roving in the longitudinal direction of the machine, the device comprising yarn guide rods extending from both sides of the intermediate drive. However, driving the oscillating device from an intermediate drive has proven to be less advantageous, since one is tied to the intermediate drive and one is accordingly restricted in terms of design. With longer machines, for example, it may be necessary to use several traversing devices. But this is in DE112012005348T5 not possible at all.

JP06-019576Y offenbart eine am Kopf angetriebene Changiervorrichtung zur Vorgarnverlegung, die mit einer Walze über ein Getriebe verbunden ist. Auch hier ist es nachteilig, dass bei längeren Maschinen die Changiervorrichtung(en) nicht an einer beliebigen Stelle angesetzt werden kann oder können. Konstruktiv ist diese Lösung entsprechend sehr limitierend. JP06-019576Y discloses a head driven traversing device for roving transfer connected to a roller via a gear. Here, too, it is disadvantageous that in the case of longer machines the traversing device(s) cannot or cannot be attached at any desired point. Structurally, this solution is correspondingly very limiting.

DE19608709 offenbart eine Travisiervorrichtung, bei der eine Vielzahl von Fadenführungen auf einer langen, hin- und herbewegten Stange angeordnet sind, welche mit einem Nockengetriebe in Verbindung steht und eine Vielzahl von Kreuzspulen gleichzeitig formt. DE19608709 discloses a traverse device in which a plurality of yarn guides are arranged on a long reciprocating rod which is linked to a cam gear and forms a plurality of cheeses simultaneously.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt somit die Aufgabe zugrunde, eine Ringspinnmaschine mit einer Vorgarnverlegung und ein Verfahren zum Betrieb dieser Ringspinnmaschine zu schaffen, die einfacher als die aus dem Stand der Technik bekannten Ringspinnmaschinen ist und die die Nachteile aus dem Stand der Technik vermeidet.The invention is therefore based on the object of creating a ring spinning machine with a roving transfer and a method for operating this ring spinning machine which is simpler than the ring spinning machines known from the prior art and which avoids the disadvantages of the prior art.

Der Erfindung liegt weiter die Aufgabe zugrunde, eine Ringspinnmaschine mit einer Vorgarnverlegung und ein Verfahren zum Betrieb dieser Ringspinnmaschine zu schaffen, die in Bezug auf die Changiervorrichtung insbesondere bei längeren Maschinen konstruktiv eine grössere Flexibilität erlaubt.The invention is also based on the object of creating a ring spinning machine with a roving traverse and a method for operating this ring spinning machine which, with regard to the traversing device, allows greater design flexibility, particularly in the case of longer machines.

Der Erfindung liegt weiter die Aufgabe zugrunde, eine Ringspinnmaschine mit einer Vorgarnverlegung und ein Verfahren zum Betrieb einer Ringspinnmaschine zu schaffen, in der über die Länge verteilt, mehrere, voneinander unabhängige Changiervorrichtungen verteilt angeordnet werden können.The invention is also based on the object of creating a ring spinning machine with a roving transfer and a method for operating a ring spinning machine in which a plurality of mutually independent traversing devices can be distributed over the length.

Die Aufgaben der vorliegenden Erfindung werden durch eine Ringspinnmaschine bzw. einem Verfahren zum Betrieb einer Ringspinnmaschine entsprechend den Merkmalen des Oberbegriffs der unabhängigen Ansprüche durch den entsprechenden kennzeichnenden Teil gelöst. Insbesondere werden die Aufgaben dadurch gelöst, dass die Changiervorrichtung von der Einlaufunterwalze angetrieben ist bzw. wird.The objects of the present invention are achieved by a ring spinning machine and a method for operating a ring spinning machine according to the features of the preamble of the independent claims by the corresponding characterizing part. In particular, the tasks are solved in that the traversing device is or is driven by the infeed bottom roller.

Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject matter of the dependent claims.

Vorteilhaft ist diese Lösung, die unabhängig von einem möglichen Mittenantrieb ist, da nun die Changiervorrichtung an einer beliebigen Stelle der Ringspinnmaschine angeordnet werden kann, was die konstruktive Flexibilität erhöht. Die Changiervorrichtung kann mit der Einlaufunterwalze je nach Ausführungsform über eine Kette oder einen Riemen verbunden werden. Auf die Einlaufunterwalze ist ein Antriebsrad aufgesetzt, das die Kette oder den Riemen antreibt. Es ist beispielsweise möglich, das Antriebsrad dort anzuordnen, wo die Einlaufunterwalze gelagert ist. Die Einlaufunterwalze selbst wird am Kopf oder Fuss der Ringspinnmaschine angetrieben.This solution, which is independent of a possible central drive, is advantageous since the traversing device can now be arranged at any point on the ring spinning machine, which increases the structural flexibility. The traversing device can be connected to the infeed bottom roller via a chain or a belt, depending on the design. A drive wheel that drives the chain or belt is placed on the infeed lower roller. For example, it is possible to arrange the drive wheel where the infeed bottom roller is mounted. The lower infeed roll itself is driven at the head or foot of the ring spinning machine.

In Längsrichtung der Ringspinnmaschine können auch mehrere, unabhängig voneinander betriebene Changiervorrichtungen vorhanden sein. Die Vorgarnleitschienen werden in diesem Fall getrennt und separat gelagert. Diese Ausführungsform erlaubt ebenfalls eine grössere konstruktive Freiheit in der Ausgestaltung der Ringspinnmaschine.In the longitudinal direction of the ring spinning machine, there can also be several traversing devices operated independently of one another. In this case, the roving guide rails are separated and stored separately. This embodiment also allows greater structural freedom in the configuration of the ring spinning machine.

Zur besseren Führung des Vorgarns werden die Vorgarnleitschienen mit einer Vielzahl von Trichtern ausgestattet, die das Vorgarn zu den Streckenwerken führen. Die Vielzahl von Streckwerken kann symmetrisch auf zwei Seiten einer Längsachse der Ringspinnmaschine angeordnet sein, wobei die Changiervorrichtung mittig dazwischen angeordnet ist. Damit werden die Vorgarnleitschienen auf beiden Seiten von derselben Changiervorrichtung angetrieben. Die Changiervorrichtung kann beispielsweise aus einem Kegelgetriebe oder einer Nuttrommel bestehen. Die Changiervorrichtung ist mit einer Kurvenscheibe und zwei seitlichen Schwenkhebeln verbunden, wobei die Schwenkhebel jeweils mit einer Vorgarnleitschiene verbunden sind.For better guidance of the roving, the roving guide rails are equipped with a large number of funnels that guide the roving to the drawing frames. The plurality of drafting systems can be arranged symmetrically on two sides of a longitudinal axis of the ring spinning machine, with the traversing device being arranged centrally between them. This means that the roving guide rails are driven on both sides by the same traversing device. The traversing device can consist, for example, of a bevel gear or a grooved drum. The traversing device is connected to a cam disc and two lateral pivoting levers, the pivoting levers each being connected to a roving guide rail.

Vorteilhaft besteht das Streckwerk aus drei Walzenpaaren, wobei die ersten beiden Walzenpaare für den Vorverzug des Vorgarns und die zweiten beiden Walzenpaare für den Hauptverzug des Vorgarns verantwortlich sind.Advantageously, the drafting system consists of three pairs of rollers, the first two pairs of rollers being responsible for the predrafting of the roving and the second two pairs of rollers being responsible for the main drafting of the roving.

Weitere Vorteile der Erfindung sind anhand eines nachfolgend beschriebenen und gezeigten Ausführungsbeispiels zu entnehmen.Further advantages of the invention can be gathered from an exemplary embodiment which is described and shown below.

Wege zur Ausführung der ErfindungWays to carry out the invention

Fig. 1 zeigt schematisch eine erfindungsgemässe Ringspinnmaschine 1, die über eine Vielzahl von nebeneinander angeordneten Spinnstellen 2 verfügt. Die Spinnstellen 2 befinden sich in einer Längsrichtung x angeordnet zwischen einem Kopf 31 und einem Fuss 32 der Ringspinnmaschine 1. Kopf 31 und Fuss 32 der Ringspinnmaschine 1 können Lager, Antriebe, Steuerung, etc. enthalten, die für den Betrieb der Maschine notwendig sind. Wie man weiter beispielsweise an zwei in der Fig. 1 schematisch dargestellten Spinnstellen 2 sieht, besteht jede Spinnstelle 2 aus einer Vorgarnspule 4, die oberhalb eines Streckwerks 5 angeordnet ist, und auf der ein Vorgarn 6 aufgewickelt ist. Das Vorgarn 6 läuft von der Vorgarnspule 4 über das Streckwerk 5, wo es verstreckt wird, um dann zu einem Garnbildungelement geführt zu werden. Die Ringspinnmaschine 1 kann zudem einen Mittenantrieb 8 zum Antrieb mindestens einer Walze des Streckwerks 5, die vorzugsweise die Mittelwalze ist, aufweisen. Der Mittenantrieb 8 ist zwischen dem Kopf 31 und dem Fuss 32 der Ringspinnmaschine 1 angeordnet. Weitere Antriebe der verschiedenen Walzen der Streckwerke 5 befinden sich in dem Kopf 31 und/oder dem Fuss 32 der Ringspinnmaschine 1. Zusätzlich ist in der Fig. 1 schematisch eine Changiervorrichtung 9 zur Vorgarnverlegung ersichtlich. Die Vielzahl von Streckwerken 5 ist vorzugsweise um eine Längsachse symmetrisch auf zwei Seiten der Ringspinnmaschine 1 angeordnet, wobei die Changiervorrichtung 9 mittig dazwischen angeordnet ist, so dass diese die Vorgarnleitschienen auf jeder Seite antreibt. Wie in der Fig. 1 dargestellt können gemäss einem weiteren Ausführungsbeispiel der Erfindung mehrere, voneinander unabhängige Changiervorrichtungen 9 vorgesehen werden. Beispielhaft sind zwei Changiervorrichtungen 9 dargestellt. Die Vorgarnleitschienen 14 müssten in diesem Fall getrennt und separat gelagert werden. Der Aufbau und Betrieb der Changiervorrichtung 9 wird mit Bezug auf die Fig. 2 näher erläutert. 1 shows schematically a ring spinning machine 1 according to the invention, which has a large number of spinning positions 2 arranged next to one another. The spinning positions 2 are located in a longitudinal direction x between a head 3 1 and a foot 3 2 of the ring spinning machine 1. Head 3 1 and foot 3 2 of the ring spinning machine 1 can contain bearings, drives, controls, etc., which are necessary for the operation of the machine are necessary. How to continue example at two in the 1 Schematically illustrated spinning positions 2 sees, each spinning position 2 consists of a roving bobbin 4, which is arranged above a drafting system 5, and on which a roving 6 is wound. The roving 6 runs from the roving bobbin 4 via the drafting system 5, where it is drafted, in order to then be guided to a yarn-forming element. The ring spinning machine 1 can also have a central drive 8 for driving at least one roller of the drafting system 5, which is preferably the central roller. The central drive 8 is arranged between the head 3 1 and the foot 3 2 of the ring spinning machine 1 . Other drives of the various rollers of the drafting systems 5 are located in the head 3 1 and/or the foot 3 2 of the ring spinning machine 1. In addition, 1 a traversing device 9 for roving laying can be seen schematically. The plurality of drafting devices 5 are preferably arranged symmetrically about a longitudinal axis on two sides of the ring spinning machine 1, with the traversing device 9 being arranged centrally in between, so that it drives the roving guide rails on each side. Like in the 1 shown, according to a further exemplary embodiment of the invention, several traversing devices 9 that are independent of one another can be provided. Two traversing devices 9 are shown as an example. The roving guide rails 14 would have to be separated and stored separately in this case. The structure and operation of the traversing device 9 is with reference to the 2 explained in more detail.

Fig. 2 zeigt eine schematische Darstellung gemäss Schnitt II-II in der Fig. 1, wobei die Fig. 2 beispielhaft nur eine Seite der Changiervorrichtung 9 zeigt. Das Vorgarn 6 wird durch das Streckwerk 5 geführt, das in der Fig. 2 lediglich schematisch dargestellt ist, und das im gezeigten Beispiel aus drei verschiedenen Walzenpaaren besteht. Das erste Walzenpaar ist das Einlaufwalzenpaar 10 und besteht aus einer angetriebenen Einlaufunterwalze 101 und einer gegen gelagerten Einlaufoberwalze 102, das zweite Walzenpaar ist das Mittelwalzenpaar 11 und besteht aus einer angetriebenen Mittelunterwalze 111 und einer gegen gelagerten Mitteloberwalze 112 und das dritte Walzenpaar ist das Auslaufwalzenpaar 12 und besteht aus einer angetriebenen Auslaufunterwalze 121 und einer gegen gelagerten Auslaufoberwalze 122. Die Unterwalzen laufen in Vorgarnlaufrichtung beim Betrieb der Ringspinnmaschine 1 jeweils mit steigenden Geschwindigkeiten, wobei die ersten beiden Walzenpaare 10, 11 für den Vorverzug des Vorgarns 6 und die zweiten beiden Walzenpaare 11, 12 für den Hauptverzug des Vorgarns 6 verantwortlich sind. 2 shows a schematic representation according to section II-II in FIG 1 , where the 2 shows only one side of the traversing device 9 as an example. The roving 6 is guided through the drafting system 5, which is in the 2 is shown only schematically, and consists of three different pairs of rollers in the example shown. The first pair of rollers is the infeed roller pair 10 and consists of a driven lower infeed roller 10 1 and a counter-supported upper infeed roller 10 2 , the second roller pair is the middle roller pair 11 and consists of a driven middle lower roller 11 1 and a counter-supported middle upper roller 11 2 and the third pair of rollers is the outlet roller pair 12 and consists of a driven lower outlet roller 12 1 and a counter-supported upper outlet roller 12 2 . The bottom rollers run in the roving direction during operation of the ring spinning machine 1 with increasing speeds, with the first two roller pairs 10, 11 being responsible for the pre-drafting of the roving 6 and the second two roller pairs 11, 12 being responsible for the main drafting of the roving 6.

Wie es in der Fig. 2 nun sichtbar ist, wird die Changiervorrichtung 9 erfindungsgemäss über eine Kette oder einen Riemen 13 von der Einlaufunterwalze 101 angetrieben. Die Changiervorrichtung 9 weist hierzu ein Antriebsrad 16 auf, das mit der Kette oder dem Riemen 13 verbunden ist. Die Kette oder der Riemen 13 wird von einem Antriebsrad 19, das auf der Einlaufunterwalze 101 sitzt, angetrieben. Die Einlaufunterwalze 101 wird wiederum von einem nicht dargestellten Motor an einem Kopf 31 (oder einem Fuss 32) der Ringspinnmaschine 1 angetrieben. Vorteilhaft ist diese Lösung, die unabhängig von einem möglichen Mittenantrieb 8 ist, da nun die Changiervorrichtung 9 an einer beliebigen Stelle zwischen Kopf 31 und Fuss 32 der Ringspinnmaschine 1 angeordnet werden kann. Die Changiervorrichtung 9 setzt die Bewegung des Antriebrads 16 über einen internen Mechanismus (beispielsweise ein Kegelgetriebe) und die Kurvenscheibe 17 in eine Bewegung der Schwenkhebel 18 um. Zu dem gewünschten Zweck ist auch der Einsatz einer Nutentrommel denkbar, die die Bewegung des Antriebsrades 16 in eine Bewegung der Schwenkhebel 18 umsetzt. Wie in der Fig. 2 ersichtlich, ist der Schwenkhebel 18 mit der Vorgarnleitschiene 14 verbunden, auf der eine der Spinnstellen 2 entsprechende Anzahl Trichter 15 sitzen, die das Vorgarn 6 dem entsprechenden Streckwerk 5 zuführen. Entsprechend der Hin- und Herbewegung der Vorgarnleitschiene 14 in Längsrichtung x der Ringspinnmaschine 1 und der Trichter 15 wird das Vorgarn 6 dem Streckwerk 5 versetzt zugeführt.Like it in the 2 is now visible, the traversing device 9 is driven according to the invention via a chain or a belt 13 from the infeed bottom roller 10 1 . For this purpose, the traversing device 9 has a drive wheel 16 which is connected to the chain or the belt 13 . The chain or belt 13 is driven by a drive wheel 19 which sits on the infeed lower roller 10 1 . The infeed bottom roller 10 1 is in turn driven by a motor (not shown) on a head 3 1 (or a foot 3 2 ) of the ring spinning machine 1 . This solution, which is independent of a possible central drive 8 , is advantageous since the traversing device 9 can now be arranged at any point between the head 3 1 and the foot 3 2 of the ring spinning machine 1 . The oscillating device 9 converts the movement of the drive wheel 16 into a movement of the pivoting lever 18 via an internal mechanism (for example a bevel gear) and the cam disc 17 . For the desired purpose, the use of a grooved drum is conceivable that the movement of the drive wheel 16 in a Movement of the pivoting lever 18 is implemented. Like in the 2 As can be seen, the pivoting lever 18 is connected to the roving guide rail 14 on which a number of funnels 15 corresponding to the spinning positions 2 are seated, which feed the roving 6 to the corresponding drafting system 5 . According to the reciprocating movement of the roving guide rail 14 in the longitudinal direction x of the ring spinning machine 1 and the funnel 15, the roving 6 is fed to the drafting system 5 in an offset manner.

Aus Fig. 3 wird deutlich, dass Schwenkhebel 18 zur Changierung der Vorgarnleitschienen 14, auf der die Trichter 15 angeordnet sind, auf beiden Seiten angeordnet sind. Die Einlaufunterwalze 101 weist das Antriebsrad 19 auf, welches an einem Ende oder in der Mitte angeordnet sein kann, und welches über die Kette oder den Riemen 13 mit dem Antriebsrad 16 verbunden ist und dieses antreibt. Es ist beispielsweise möglich, das Antriebsrad 19 dort anzuordnen, wo die Einlaufunterwalze 101 gelagert ist. Da die Changiervorrichtung 9 zwischen dem Kopf 31 und dem Fuss 32 der Ringspinnmaschine 1 angeordnet ist, erstrecken sich die Vorgarnleitschienen 14 von der Changiervorrichtung 9 aus in der Längsrichtung x der Ringspinnmaschine 1 in beide Richtungen.the end 3 it becomes clear that pivoting levers 18 for oscillating the roving guide rails 14 on which the funnels 15 are arranged are arranged on both sides. The infeed lower roller 10 1 has the drive wheel 19 which can be arranged at one end or in the middle and which is connected via the chain or belt 13 to the drive wheel 16 and drives it. It is possible, for example, to arrange the drive wheel 19 where the infeed lower roller 10 1 is mounted. Since the traversing device 9 is arranged between the head 31 and the foot 32 of the ring spinning machine 1 , the roving guide rails 14 extend from the traversing device 9 in the longitudinal direction x of the ring spinning machine 1 in both directions.
