Description

Die Erfindung betrifft ein Spinnereimaschinen-Streckwerk mit Unterwalzen und mit Oberwalzen sowie mit Unterriemchen und mit Oberriemchen nach dem Oberbegriff des Ansprüchs 1.The invention relates to a spinning machine drafting system with lower rollers and with upper rollers and with Unterriemchen and Oberriemchen according to the preamble of Ansprüchs. 1

Neben Streckwerken allein zum Verfeinern einer Faserlunte und Abliefern der verfeinerten Faserlunte sind Streckwerke bekannt (DE 43 23 472 C2), die ah ihrem Ausgang ein Luntenverdichtungsaggregat aufweisen, durch das die verzogene Faserlunte vor ihrem Abliefern an das Ring/Läuter/Spindelaggregat einem seitlichem Zusammenfassen, einem sogenannten Verdichtungsspinnen unterzogen wird.In addition to drafting systems alone for refining a roving and delivering the refined roving drafting units are known (DE 43 23 472 C2), ah at their output a Luntenverdichtungsaggregat by which the warped roving prior to their delivery to the ring / lauter / Spindelaggregat a lateral summarize, subjected to a so-called compaction spinning.

Für dieses Verdichtungsspinnen sind unterschiedliche Einrichtungen vorgeschlagen worden. Die vorliegende Erfindung geht von einem pneumatischen Luntenverdichtungsaggregat aus, bei dem der Faserverbänd durch Ansaugen an eine sich entlang des Faserlaufes erstreckende Lochreihe seitlich zusammengefaßt wird, durch die mittels Saugzuges Luft eingesaugt wird. Diese Lochreihe kann in einer Streckwerkswalze und zwar sowohl in einer. Unterwalze als auch in einer Oberwalze oder in einem den Faserverband führenden Riemchen angeordnet sein. Die Erfindung ist nachfolgend anhand einer Einrichtung beschrieben, bei der die Lochreihe in einem einer Oberwalze zugeordneten Riemchen angeordnet ist.Different devices have been proposed for this compaction spinning. The present invention is based on a pneumatic Luntenverdichtungsaggregat, in which the fiber composites is summarized by sucking on a line of fibers extending along the row of holes through which air is sucked by means of induced draft. This row of holes can be in a drafting roller and both in one. Under roller as well as in a top roll or in a fiber dressing leading straps be arranged. The invention is described below with reference to a device in which the row of holes is arranged in a top roller assigned straps.

Weiterer Stand der Technik betrifft das sogenannte DREF-Ringspinnverfahren (Textilpraxis International 1992, Seiten 189 und 190 "DREF-Ringspinnverfahren 1993 für Spinnereien verfügbar").Further prior art relates to the so-called DREF ring spinning process (Textilpraxis International 1992, pages 189 and 190 "DREF ring spinning process 1993 available for spinning mills").

Bei diesem bekannten Verfahren ist die Möglichkeit des Einbaus an bereits bestehenden alten Ringspinnmaschinen vorgesehen.In this known method, the possibility of installation on existing old ring spinning machines is provided.

Auch beim sogenannten "Verdichtungsspinnen", welches mit einem perforierten Oberriemchen arbeitet, wurde bereits vorgeschlagen, ältere Maschinen entsprechend nachzurüsten ("Untersuchung verschiedener Faserbündelungsmethoden zur Eliminierung des Spinndreiecks", mitex 4/96 1996).Also in so-called "compaction spinning", which works with a perforated upper apron, it has already been proposed to retrofit older machines accordingly ("investigation of different fiber bundling methods for eliminating the spinning triangle", mitex 4/96 1996).

Darüber hinaus ist es bekannt, durch Einbau einer perforierten Saugtrommel eine Ringspinnmaschine entsprechend umzurüsten (ATA Journal Juni/Juli 1995, Seiten 28 - 30).In addition, it is known to retrofit a ring spinning machine by installing a perforated suction drum (ATA Journal June / July 1995, pages 28 - 30).

Bisweilen soll auf die Verdichtungsfunktion des Streckwerkes verzichtet werden. Dies kann ersichtlich nicht einfach durch Abstellen des Besaugens des Luntenverdichtungsaggregates erfolgen. weil dadurch die Führung der Fasern in dem bis dahin als Verdichtungsfeld wirkenden Bereich unter dem perforierten Riemchen nicht mehr gegeben ist Auch ein Ersetzen des Luntenverdichtungsaggregates durch eine einfache Walze ist nicht zweckmäßig, weil in dem letzten Streckfeld keine Führung der Fasern vorhanden ist und dadurch die Qualität des erzeugten Fadens beeinträchtigt werden würde, Der Erfindung war daher die Aufgabe gestellt, hierfür eine einfache Lösung anzugeben.Sometimes should be dispensed with the compression function of the drafting system. Obviously, this can not be done simply by turning off the sweeping of the Luntenverdichtungsaggregates. because thereby the leadership of the fibers in the hitherto acting as compaction field under the perforated belt is no longer given Also a replacement of Luntenverdichtungsaggregates by a simple roller is not appropriate because in the last draft field no guidance of the fibers is present and thus the quality The invention was therefore the task of providing a simple solution for this purpose.

Sie löst diese Aufgabe durch die.im Kennzeichen des Hauptanspruches aufgeführten Merkmale. Auf diese Weise wird der Vorteil erreicht, daß die durch das Entnehmen bzw. das Einsetzen des stets am Ausgang des Streckwerkes angeordneten Luntenverdichtungsaggregates verursachte Veränderung des Streckwerkes und damit des Fadenlaufes vom Streckwerk zum nachgeordneten Fadenführer korrigiert werden kann. Falls dern Ausgangswalzenpaar des Streckwerkes eine Absaugvorrichtung oder eine Fadenbruch-Abstellvorrichtung zugeordnet ist, wird durch die erfindungsgemäße Ausbildung des Streckwerkes zudem der Vorteil erreicht, daß diese Vorrichtungen ihre Funktionen ohne bauliche Änderung weiterhin erfüllen können.It solves this task by die.im characteristics of the main claim listed features. In this way, the advantage is achieved that caused by the removal or the insertion of the always arranged at the output of the drafting Luntenverdichtungsaggregates change in the drafting system and thus the yarn path from the drafting to downstream thread guide can be corrected. If the output roller pair of the drafting system is assigned a suction device or a yarn break-off device, the design of the drafting system according to the invention additionally achieves the advantage that these devices can continue to perform their functions without structural alteration.

Besonders einfach gestaltet sich das Verändern der Positionen der Streckwalzen dann, wenn die Lagerungen der Unterwalzen bzw. die Halterungen der Oberwalzen gleich ausgebildet sind, so daß sie ohne weiteres in andere Positionen versetzt und eingesetzt werden können. Vorteilhaft ist auch ein zumindest annähernd gleicher Durchmesser der Unterwalzen des Streckwerkes, weil dadurch ihre Umfangsflächen auch in anderen Positionen zumindest annähernd in gleicher Höhe liegen und die in aller Regel ebene Faserlauffläche zumindest annähernd eben bleibt.Changing the positions of the drafting rollers is particularly simple if the bearings of the lower rollers or the holders of the upper rollers are of the same design, so that they can be easily moved to other positions and used. Also advantageous is an at least approximately the same diameter of the lower rollers of the drafting system, because thereby their peripheral surfaces are in other positions at least approximately the same height and the usually flat fiber surface remains at least approximately flat.

Wie aus Fig. 1 erkennbar, weist das Streckwerk 1 in seiner Anordnung zum Verdichtungsspinnen vier in aller Regel geriffelte Unterwalzen 2, 3, 4 und 5 aus Stahl auf. Die Unterwalze 3, die häufig "gekordelt", d.h. kreuzgeriffelt ist, wird von einem Uriterriemchen 11 umschlungen, das vor dem nachfolgenden Walzenpaar auch um eine hier nicht dargestellte Wendeschiene geführt ist. Die Ausgangsunterwalze 5 ist in aller Regel in der Stanze 6, die anderen Unterwalzen sind dagegen in Schlitten 7, 8 und 9 gelagert, die in der Stanze in Richtung des Faserdurchlaufes verstellbar sind. Die Lager der Unterwalzen 2, 3, 4 und 5 sind gleich ausgebildet, so daß jede Unterwalze in jeden der Schlitten 7, 8 oder 9 bzw. in die Lagerstelle in der Stanze 6 eingelegt werden kann. Die Unterwalzen 2, 3, 4 und 5 weisen auch zumindest annähernd gleiche Durchmesser auf, so daß bei einem Versetzen der Unterwalzen die Verzugsebene des Streckwerkes 1 mindestens annähernd aufrecht erhalten wird.As can be seen from Fig. 1, the drafting system 1 in its arrangement for compaction spinning four generally corrugated bottom rollers 2, 3, 4 and 5 made of steel. The lower roll 3, which is often "tied", i. is grooved, is wrapped by a Uriterriemchen 11, which is also performed before the subsequent pair of rollers around a turning rail, not shown here. The output sub-roller 5 is usually in the punch 6, the other lower rollers, however, are mounted in slides 7, 8 and 9, which are adjustable in the punch in the direction of fiber passage. The bearings of the lower rollers 2, 3, 4 and 5 are the same, so that each lower roller in each of the carriage 7, 8 or 9 or in the bearing in the punch 6 can be inserted. The lower rollers 2, 3, 4 and 5 also have at least approximately the same diameter, so that when displacing the lower rollers, the drafting plane of the drafting system 1 is at least approximately maintained.

Den Unterwalzen 2 und 4 sind normale Oberwalzen 10 mit elastischem Bezug zugeordnet. Die der Unterwalze 3 zugeordnete Oberwalze 10 wird von einem.Oberriemchen 12 umschlungen, das von einem geläufigen, hier nicht dargestellten Riemchenkäfig mit Umlenkschiene geführt ist.The lower rollers 2 and 4 are associated with normal top rollers 10 with elastic cover. The upper roller 10 associated with the lower roller 3 is surrounded by a top apron 12, which is guided by a common apron cage, not shown here, with deflecting rail.

Der Ausgangsunterwalze 5 ist eine Oberwalze 13 zugeordnet, die ebenfalls durch ein Oberriemchen 14 umschlungen ist. Dieses Oberriemchen 14 weist eine Lochreihe 15 auf, die mittig um seinen Umfang angeordnet ist. Innerhalb des Oberriemchens 14 ist ferner eine Kammer 16 vorgesehen, die gegen das der Faserlunte 17 zugewandte Trum des Oberriemchens offen oder mit einer Perforation versehen und über eine Rohrleitung 18 mit einer hier nicht dargestellten Saugquelle verbunden ist. Die Oberwalze 13, das Oberriemchen 14 und die Kammer i 6 bilden ein Verdichtungsaggregat 19.The output sub-roller 5 is associated with a top roller 13, which is also looped by a top apron 14. This Oberriemchen 14 has a row of holes 15 which is arranged centrally around its circumference. Within the upper apron 14, a chamber 16 is further provided, which is open or provided with a perforation against the strand of the roving 17 facing Trum of Oberriemchens and connected via a pipe 18 with a suction source, not shown here. The upper roller 13, the upper apron 14 and the chamber i 6 form a compacting unit 19th

Die Oberwalzen 10 und 13 sind in der Regel als sogenannte Walzenzwillinge ausgeführt und mittels Lenkern 20 in einem geläufigen Trag- und Belastungsarm 21 gehaltert. Die Walzenhalter 22 dieserLenker20 sind gleich ausgebildet, so daß die Oberwalzen 10, 13 ohne weiteres in einer anderen Position in einen der Walzenhalter einsetzbar sind.The top rollers 10 and 13 are usually designed as so-called roll twins and held by means of links 20 in a common support and loading arm 21. The roller holders 22 of this handlebar 20 are formed the same so that the top rollers 10, 13 are readily insertable in another position in one of the roller holders.

Dem Streckwerk 1 ist ein Vorgarnführer23 vorgeordnet und ein Fadenführer 24 und ein nicht dargesielltes Ring/Läufer/Spindel-Aggregat geläufiger Bauweise nachgeordnet. Beim Lauf des Streckwerkes wird das zugeführte Vorgarn 25 zwischen den aufeinander folgenden Walzenpaaren, also dem Eingangswalzenpaar 2/10, dem Oberriemchenwalzenpaar 3-11/10-12 und dem Lieferwalzenpaar 4/10 fortlaufend verfeinert und als Faserlunte 17 in seiner endgültigen Feinheit an das aus der Unterwalze 5 und dem Verdichtungsaggregat 19. bestehenden Verdichtungs- und Ausgangswalzenpaar abgeliefert. Beim Verzug ist diese Faserlunte 17 in die Breite gelaufen. Durch Ansaugen der Fasern an die schmale Linie der Lochreihe 15 im Oberriemchen 14 des Verdichtungsaggregates 19 wird die Faserlunte 17 zusammengefaßt und verdichtet und schmal sowie ohne abstehende Fasern als Faden 26 über den Fadenführer 24 an das Ring/Läufer/Spindel-Aggregat abgeliefert.The drafting 1 is a Vorgarnführer23 upstream and downstream of a yarn guide 24 and a not dargesielltes ring / rotor / spindle assembly of common construction. When running the drafting system, the supplied roving 25 between the successive pairs of rollers, ie the pair of input rollers 2/10, the Oberriemchenwalzenpaar 3-11 / 10-12 and the pair of delivery rollers 4/10 continuously refined and as a roving 17 in its final fineness of the the lower roller 5 and the compression unit 19th existing compression and output roller pair delivered. When warping this roving 17 has gone in the width. By sucking the fibers to the narrow line of the row of holes 15 in Oberriemchen 14 of the compression unit 19, the roving 17 is summarized and compressed and delivered narrow and without protruding fibers as a thread 26 via the yarn guide 24 to the ring / rotor / spindle unit.

Wenn auf die Verdichtungsfunktion verzichtet werden soll, können das Verdichtungsaggregat 19 und die Unterwalze 5 entnommen werden.If you want to dispense with the compression function, the compression unit 19 and the lower roller 5 can be removed.

Erfindungsgemäß ist vorgesehen, daß nach Entnehmen des Verdichtungsaggregates 19 und der ihm zugeordneten Unterwalze 5 die verbliebenen Streckwalzen um jeweils eine Position in Richtung des Laufes der Faserlunte 17 weitergerückt werden. Es wird also die Unterwalze 4 in die bisher von der Unterwalze 5 eingenommene Lagerstelle in der Stanze 6, die Unterwalze 3 in die Lagerstelle des Schlittens 9 und die Unterwalze 2 in die Lagerstelle des Schlittens 8 versetzt, der Schlitten 7 bleibt frei. Dabei sind gegebenenfalls die Abstände der Schlitten 8 und 9 zur testen Position der neuen Ausgangsunterwalze 4 in der Stanze 6 anzupassen. Entsprechend sind die Oberwalzen 10 in die Walzenhalter22 der entsprechenden Lenker 20 zu versetzen. Aus Fig. 2 sind die neuen Positionen der Unterwalzen, der Oberwalzen, der Unterriemchen und der Oberriemchen anhand der ihnen zugeordneten Bezugsziffern erkennbar. Dadurch, daß das bisherige Lieferwalzenpaar 4/10 an die Stelle des bisherigen Ausgangswalzenpaares 5/13 getreten ist, ist wieder die gleiche Lauflänge und sind wieder die gleichen Ablaufwinkel des Fadens 26 gegeben wie mit Verdichtungsfunktion. Da der Vorgarnführer 23 zweckmäßigerweise in seiner Position verbleibt, b leibt vorteilhafterweise auch der Zulauf des Vorgarnes 25 unverändert.According to the invention it is provided that after removal of the compression unit 19 and its associated lower roller 5, the remaining drafting rollers are advanced by one position in the direction of the run of the roving 17. Thus, it is the lower roller 4 is added to the previously occupied by the lower roller 5 bearing in the punch 6, the lower roller 3 in the bearing of the carriage 9 and the lower roller 2 in the bearing of the carriage 8, the carriage 7 remains free. If necessary, the distances between the carriages 8 and 9 to the test position of the new output lower roller 4 in the punch 6 are adapted. Accordingly, the top rollers 10 are to be placed in the roll holder 22 of the corresponding arm 20. From Fig. 2, the new positions of the lower rollers, the top rollers, the Unterriemchen and Oberriemchen be recognized by their associated reference numerals. The fact that the previous pair of delivery rollers 4/10 has taken the place of the previous pair of output rollers 5/13, again the same run length and again the same outlet angle of the thread 26 are given as with compression function. Since the Vorgarnführer 23 expediently remains in its position, b advantageously also leaves the feed of the roving 25 unchanged.

Aus Fig. 3 ist erkennbar, daß anstelle der Ausgangsunterwalze 5 auch die Zwischenunterwalze 4 entnommen werden kann. Die Ausgangsunterwalze 5 bleibt dabei in ihrer Position, die an deren Arbeitsorgane des Streckwerkes rücken um jeweils eine Position in Richtung des Laufes der Faserlunte 17 weiter.From Fig. 3 it can be seen that instead of the output lower roller 5 and the intermediate lower roller 4 can be removed. The output sub-roller 5 remains in its position, which move to the working organs of the drafting system by one position in the direction of the run of the roving 17 on.

Beim Umstellen des Streckwerkes 1 auf Verdichtungsfunktion müssen umgekehrt wie vorstehend beschrieben die Streckwerkswalzen mit Streckfunktion entgegen der Materiallaufrichtung nach hinten versetzt und das Verdichtungsaggregat 19 und die Unterwälze 5 bzw. 4 eingesetzt werden.When changing the drafting system 1 to the compression function vice versa as described above, the drafting rollers with stretching function against the material direction offset backwards and the compression unit 19 and the lower rollers 5 and 4 are used.
