Description

Ringspinnmaschine  Ring spinning machine
Technisches Gebiet Technical area
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 preamble of the independent claims.
Stand der Technik State of the art
Ringspinnmaschinen mit Changiervorrichtung zur Vorgarnverlegung sind an sich bereits bekannt. Bei der Zuführung des Vorgarns zum Streckwerk wird durch die Vorgarnverle- gung erreicht, dass die Abnutzung der Streckwerkswalzen, die durch ein gleichmässi- ges 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. DE1 12012005348T5 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 Zwi- schenantrieb 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 DE1 12012005348T5 gar nicht möglich. 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. Ring spinning machines with traversing device for roving laying are already known per se. When the roving is fed to the drafting system, the roving installation reduces the wear on the drafting rollers, which would result from uniform feeding of the roving at one point. The wear of the rollers is rather distributed by laying the feeder to a specific, defined area. The traversing device is connected for this purpose with Vorgarnleitschienen that feed the roving the drafting system. DE1 12012005348T5 discloses a spinning machine with a plurality of spinning stations, each with a drafting system and an intermediate drive. A drafting system has at least two drafting rollers, which are coupled with 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 guiding rods extending from both sides of the intermediate drive. To drive the oscillating device of an intermediate drive, however, has proven to be of little advantage, since you are bound to the intermediate drive and you constructively limits accordingly. With longer machines, it may be necessary, for example, to use several traversing devices. However, this is not possible in DE1 12012005348T5. JP06-019576Y discloses a head-driven roving laying apparatus connected to a roll via a gear. Again, it is disadvantageous that with longer machines, the traversing device (s) can not be applied anywhere or can. Constructively, this solution is correspondingly very limiting.
Darstellung der Erfindung Presentation 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 to provide a ring spinning machine with a roving 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. Der Erfindung liegt weiter die Aufgabe zugrunde, eine Ringspinnmaschine mit einerThe invention is further based on the object to provide a ring spinning machine with a roving and a method for operating this ring spinning machine, which allows a greater flexibility in terms of the traversing device, especially for longer machines constructively. The invention is further based on the object, a ring spinning machine with a
Vorgarnverlegung und ein Verfahren zum Betrieb einer Ringspinnmaschine zu schaffen, in der über die Länge verteilt, mehrere, voneinander unabhängige Changiervorrichtungen verteilt angeordnet werden können. To provide roving and a method for operating a ring spinning machine, distributed in the distributed over the length, a plurality of independent traversing devices can be arranged distributed.
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 or 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 objects are achieved in that the traversing device is driven by the infeed sub-roller or is.
Vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche. 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. Advantageous embodiments of the invention are the subject of the dependent claims. This solution is advantageous, which is independent of a possible center drive, since now the traversing device can be arranged at any point of the ring spinning machine, which increases the design flexibility. The traversing device can be connected to the inlet sub-roller, depending on the embodiment via a chain or a belt. On the inlet lower roller a drive wheel is placed, which drives the chain or the belt. It is for example possible to arrange the drive wheel where the inlet lower roller is mounted. The infeed lower roll itself is driven on 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. 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 Chan- giervorrichtung 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. In the longitudinal direction of the ring spinning machine can also be present, independently operated traversing devices. The Vorgarnleitschienen be separated in this case and stored separately. This embodiment also allows greater freedom of design in the embodiment of the ring spinning machine. For better guidance of the roving, the roving guide rails are equipped with a plurality of funnels which guide the roving to the track works. The plurality of drafting devices may be arranged symmetrically on two sides of a longitudinal axis of the ring spinning machine, wherein the traversing device is arranged centrally therebetween. Thus, the roving guide rails are driven on both sides by the same conveyor. The traversing device may for example consist of a bevel gear or a grooved drum. The traversing device is connected to a cam and two lateral pivot levers, wherein the pivot levers are each connected to a Vorgarnleitschiene.
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, wherein the first two pairs of rollers are responsible for the Vorverzug the roving and the second two pairs of rollers for the main delay of the roving.
Weitere Vorteile der Erfindung sind anhand eines nachfolgend beschriebenen und gezeigten Ausführungsbeispiels zu entnehmen. Further advantages of the invention will be apparent from an embodiment described below and shown.

Changiervorrichtung und einem Streckwerk; und Traversing device and a drafting system; and
Fig. 3 eine schematische Darstellung eines Antriebs einer Changiervorrichtung; darstellen. Es werden nur für die Erfindung wichtigen Merkmale dargestellt. Gleiche Merkmale werden in unterschiedlichen Figuren gleich bezeichnet. Fig. 3 is a schematic representation of a drive of a traversing device; represent. Only features important to the invention are shown. Identical features are referred to the same in different figures.
Wege zur Ausführung der Erfindung 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 3i und einem Fuss 32 der Ringspinnmaschine 1 . Kopf 3i und Fuss 32 der Ringspinnmaschine 1 können Lager, Antriebe, Steuerung, etc. enthalten, die für den Betrieb der Maschine not- wendig 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 Ringspinnmaschi- ne 1 kann zudem einen Mittenantrieb 8 zum Antrieb mindestens einer Walze des1 shows schematically a ring spinning machine 1 according to the invention, which has a multiplicity of spinning stations 2 arranged next to one another. The spinning units 2 are arranged in a longitudinal direction x between a head 3i and a foot 3 2 of the ring spinning machine 1. Head 3i and foot 3 2 of the ring spinning machine 1 can contain bearings, drives, control, etc., which are necessary for the operation of the machine. As is further seen, for example, at two spinning stations 2 shown schematically in FIG. 1, each spinning station 2 consists of a roving bobbin 4, which is arranged above a drafting arrangement 5, and on which a roving 6 is wound. The roving 6 runs from the roving bobbin 4 via the drafting device 5, where it is stretched to then be guided to a Garnbildungelement. The ring spinning machine 1 can also have a center drive 8 for driving at least one roller of the
Streckwerks 5, die vorzugsweise die Mittelwalze ist, aufweisen. Der Mittenantrieb 8 ist zwischen dem Kopf 3i und dem Fuss 32 der Ringspinnmaschine 1 angeordnet. Weitere Antriebe der verschiedenen Walzen der Streckwerke 5 befinden sich in dem Kopf 3i und/oder dem Fuss 32 der Ringspinnmaschine 1 . Zusätzlich ist in der Fig. 1 schema- tisch eine Changiervorrichtung 9 zur Vorgarnverlegung ersichtlich. Die Vielzahl vonDrawframe 5, which is preferably the center roll, have. The center drive 8 is arranged between the head 3i and the foot 3 2 of the ring spinning machine 1. Further drives of the various rollers of the drafting units 5 are located in the head 3i and / or the foot 3 2 of the ring spinning machine 1. In addition, a traversing device 9 for roving laying is schematically shown in FIG. 1. The variety of
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 Erfin- dung 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. Draw frames 5 are preferably arranged symmetrically about a longitudinal axis on two sides of the ring spinning machine 1, wherein the traversing device 9 is arranged centrally therebetween, so that it drives the Vorgarnleitschienen on each side. As shown in FIG. 1, according to a further embodiment of the invention, a plurality of mutually independent traversing devices 9 can be provided. By way of example, two traversing devices 9 are shown. The roving guide rails 14 would have to be separated and stored separately in this case. The construction and operation of the traversing device 9 will be explained in more detail with reference to FIG.
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 10i und einer gegen gelagerten Einlaufoberwalze 102, das zweite Wal- zenpaar ist das Mittelwalzenpaar 1 1 und besteht aus einer angetriebenen Mittelunterwalze 1 1 1 und einer gegen gelagerten Mitteloberwalze 1 12 und das dritte Walzenpaar ist das Auslaufwalzenpaar 12 und besteht aus einer angetriebenen Auslaufunterwalze 12i und einer gegen gelagerten Auslaufoberwalze 122. Die Unterwalzen laufen in Vorgarnlaufrichtung beim Betrieb der Ringspinnmaschine 1 jeweils mit steigenden Ge- schwindigkeiten, wobei die ersten beiden Walzenpaare 10, 1 1 für den Vorverzug des Vorgarns 6 und die zweiten beiden Walzenpaare 1 1 , 12 für den Hauptverzug des Vorgarns 6 verantwortlich sind. Fig. 2 shows a schematic representation according to section II-II in Fig. 1, wherein the Fig. 2 shows only one side of the traversing device 9 by way of example. The roving 6 is guided by the drafting 5, which is shown only schematically in Fig. 2, and which consists in the example shown of three different pairs of rollers. The first pair of rollers is the Einlaufwalzenpaar 10 and consists of a driven inlet lower roller 10i and a counter-mounted inlet top roller 10 2 , the second pair of rollers is the middle roller pair 1 1 and consists of a driven middle lower roller 1 1 1 and a bearing against the upper middle roller 1 1 2 and the third pair of rollers is the outlet roller pair 12 and consists of a driven outlet bottom roller 12i and a counter-outlet roller top roller 12 2 . The lower rollers run in Vorgarnlaufrichtung during operation of the ring spinning machine 1 each with increasing speeds, the first two pairs of rollers 10, 1 1 are responsible for the Vorverzug the roving 6 and the second two pairs of rollers 1 1, 12 for the main delay 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 10i 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 10i sitzt, angetrieben. Die Einlaufunterwalze 10i wird wiederum von einem nicht dargestellten Motor an einem Kopf 3i (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 3i 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 As can now be seen in FIG. 2, the traversing device 9 according to the invention is driven by the infeed lower roller 10i via a chain or belt 13. The traversing device 9 has for this purpose 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 10i. The inlet sub-roller 10i is in turn driven by a motor, not shown, on a head 3i (or a foot 3 2 ) of the ring spinning machine 1. This solution is advantageous, which is independent of a possible center drive 8, since now the traversing device 9 can be arranged at any point between the head 3i and foot 3 2 of the ring spinning machine 1. The traversing device 9 converts the movement of the drive wheel 16 into a movement of the pivot levers 18 via an internal mechanism (for example a bevel gear) and the cam 17. For the desired purpose, the use of a grooved drum is conceivable, the movement of the drive wheel 16 in a Movement of the pivot lever 18 is implemented. As can be seen in FIG. 2, the
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 Vorgarnleitschie- ne 14 in Längsrichtung x der Ringspinnmaschine 1 und der Trichter 15 wird das Vorgarn 6 dem Streckwerk 5 versetzt zugeführt. Pivoting lever 18 is connected to the roving guide rail 14, on which one of the spinning stations 2 corresponding number of funnels 15 sit, which feed the roving 6 the corresponding drafting 5. In accordance with the reciprocating movement of the roving guide rails 14 in the longitudinal direction x of the ring spinning machine 1 and the funnels 15, the roving 6 is fed offset to the drafting system 5.
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 10i 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 10i gelagert ist. Da die Changiervorrichtung 9 zwischen dem Kopf 3i 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. From Fig. 3 it is clear that pivot lever 18 for traversing the Vorgarnleitschienen 14, on which the funnels 15 are arranged, are arranged on both sides. The infeed sub-roller 10i has the drive wheel 19, which may be disposed at one end or in the middle, and which is connected via the chain or the belt 13 to the drive wheel 16 and this drives. It is for example possible to arrange the drive wheel 19 where the inlet lower roller 10i is mounted. Since the traversing device 9 is arranged between the head 3i and the foot 3 2 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.
