Abstract

A drafting system is fitted with a sliver condensing unit (19) which can be removed when not required by the processing conditions. The spacing of the bearings for the lower (2-5) and upper (10-13) drafting elements is such that when the condensing unit is removed the other rollers or their function can be moved forward by one position.

Description

Die Erfindung betrifft ein Spinnereimaschinen-Streckwerk mit Unterwalzen und mit Oberwalzen sowie mit Unterriemchen und mit Oberriemchen.The invention relates to a spinning machine drafting system Bottom rollers and with top rollers as well as with bottom straps and with ankle strap.

Neben Streckwerken allein zum Verfeinern einer Faserlunte und Abliefern der verfeinerten Faserlunte sind Streckwerke bekannt (DE 43 23 472 C2), die an ihrem Ausgang ein Luntenverdichtungsaggregat aufweisen, durch das die verzogene Faserlunte vor ihrem Abliefern an das Ring/Läufer/Spindelaggregat einem seitlichem Zusammenfassen, einem sogenannten Verdichtungsspinnen unterzogen wird.In addition to drafting units alone to refine a fiber sliver and Delivery of the refined fiber sliver is known (DE 43 23 472 C2), which has a sliver compression unit at its output through which the warped fiber sliver before they are delivered to the ring / rotor / spindle unit a side summarization, a so-called compression spinning is subjected.

Für dieses Verdichtungsspinnen sind unterschiedliche Einrichtungen vorgeschlagen worden. Die vorliegende Erfindung geht von einem pneumatischen Luntenverdichtungsaggregat aus, bei dem der Faserverband 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.There are different facilities for this compression spinning been proposed. The present invention goes from a pneumatic fuse compaction unit, at which the fiber structure by sucking on along the Fiber row extending hole row summarized laterally through which air is sucked in by means of suction. This Row of holes can be in a drafting roller, both in a lower roller as well as in an upper roller or in a the straps leading the fiber structure may be arranged. The invention is described below using a device, in which the row of holes in a top roller assigned Strappy is arranged.

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 the compression function of the drafting system is said to be to be dispensed with. This cannot be seen simply by Turn off the suction of the match compression unit, because doing so will guide the fibers in the by then the area under the perforated area that acts as a compression field Strappy no longer exists. Also a replacement of the fuse compaction unit is not by a simple roller expedient because there is no guidance of the in the last stretch Fibers are present and thereby the quality of the produced Fadens would be affected. The invention was therefore asked the task to provide a simple solution for this.

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 dem 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 the in the hallmark of the main claim characteristics listed. This way the advantage achieved that by removing or inserting the sliver compaction unit always arranged at the exit of the drafting system caused change in the drafting system and thus the thread run from the drafting system to the downstream one Thread guide can be corrected. If the exit roller pair of the drafting device, a suction device or a thread break-off device is assigned by the invention Training the drafting system also the advantage achieved that these devices perform their functions without structural Can continue to meet the change.

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 is particularly easy of the drafting rollers when the bearings of the bottom rollers or the brackets of the top rollers are identical, so that it is easily moved to other positions and can be used. At least one is also advantageous approximately the same diameter of the lower rollers of the drafting system, because this means that their peripheral surfaces also in other positions are at least approximately the same height and the in generally flat fiber tread at least approximately flat remains.

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 Unterriemchen 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 device 1 has in its Arrangement for compaction spinning four usually corrugated Bottom rollers 2, 3, 4 and 5 made of steel. The bottom roller 3, which is often "corded" i.e. is cross corrugated, by wrapped around a lower strap 11, which before the following A pair of rollers also around a turning rail, not shown here is led. The output lower roller 5 is usually in the punch 6, the other lower rollers, however, are in sledges 7, 8 and 9 stored in the punch in the direction of Are adjustable. The bearings of the lower rollers 2, 3, 4 and 5 are identical, so that each lower roller in each of the carriages 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 on, so that when the lower rollers are moved, the plane of warpage of the drafting system 1 at least approximately upright is obtained.

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 bottom rollers 2 and 4 are normal top rollers 10 with elastic Assigned reference. The one assigned to the lower roller 3 Upper roller 10 is wrapped by an upper strap 12, the from a common strappy cage, not shown here is guided with a deflection 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 16 bilden ein Verdichtungsaggregat 19.An upper roller 13 is assigned to the output lower roller 5, which is also wrapped by an upper strap 14. This top strap 14 has a row of holes 15 which are in the center is arranged around its circumference. Inside the top strap 14, a chamber 16 is also provided, which against the the fiber sliver 17 facing strand of the top strap open or provided with a perforation and via a pipeline 18 connected to a suction source, not shown here is. The top roller 13, the top strap 14 and the chamber 16 form a compression 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 dieser Lenker 20 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 called Rolling twins executed and by means of links 20 in one common support and load arm 21 supported. The roller holder 22 of these links 20 are identical, so that the upper rollers 10, 13 easily in a different position can be inserted into one of the roller holders.

Dem Streckwerk 1 ist ein Vorgarnführer 23 vorgeordnet und ein Fadenführer 24 und ein nicht dargestelltes Ring/Läufer/Spindel-Aggregat geläufiger Bauweise nachgeordnet. Beim Lauf des Streckwerkes wird das zugeführte Vorgarn 25 zwischen den aufeinanderfolgenden 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.A roving guide 23 is arranged upstream of the drafting unit 1 and one Thread guide 24 and a ring / traveler / spindle unit, not shown Subordinate common construction. When running the Drafting device, the roving 25 fed between the successive Roller pairs, i.e. the input roller pair 2/10, the top apron roller pair 3-11 / 10-12 and the delivery roller pair 4/10 continuously refined and as fiber fuse 17 in its final fineness to that from the lower roller 5 and the compression unit 19 existing compression and Delivered pair of output rollers. This warp is in the warp 17 run in width. By sucking in the fibers the narrow line of the row of holes 15 in the upper strap 14 of Compression unit 19, the fiber sliver 17 is summarized and compacted and narrow and without protruding fibers as thread 26 via the thread guide 24 to the ring / traveler / spindle unit delivered.

Wenn auf die Verdichtungsfunktion verzichtet werden soll, können das Verdichtungsaggregat 19 und die Unterwalze 5 entnommen werden. Damit ergibt sich die in Fig. 2 dargestellte Anordnung. Es ist erkennbar, daß hierbei sich die Länge des - Laufes des Fadens 26 vom (neuen) Ausgangswalzenpaar 4/10 zum Fadenführer 24 und seine Umlenkwinkel an der Unterwalze 4 und am Fadenführer ändern. Dies könnte bei empfindlichen Fäden zu einer Beeinträchtigung der Fadenqualität führen. Eine der bisherigen Ausgangsunterwalze 5 zugestellte Absaugvorrichtung oder eine Fadenbruch-Abstellvorrichtung müßte entfernt oder in ihrer Lage angepaßt werden.If you want to do without the compression function, can the compaction unit 19 and the lower roller 5 removed become. This results in the one shown in FIG. 2 Arrangement. It can be seen that the length of the - Run of thread 26 from the (new) output roller pair 4/10 to Thread guide 24 and its deflection angle on the lower roller 4 and change the thread guide. This could be the case with sensitive threads impair the thread quality. One of the previous output lower roller 5 supplied suction device or a thread break stop device would have to be removed or be adjusted in their position.

Um dies zu vermeiden, ist erfindungsgemäß 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 schiitten 8 und 9 zur festen Position der neuen Ausgangsunterwalze 4 in der Stanze 6 anzupassen. Entsprechend sind die Oberwalzen 10 in die Walzenhalter 22 der entsprechenden Lenker 20 zu versetzen. Aus Fig. 3 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, bleibt vorteilhafterweise auch der Zulauf des Vorgarnes 25 unverändert.In order to avoid this, the invention provides that after removing the compression unit 19 and its associated Bottom roller 5 the remaining stretching rollers each a position in the direction of the sliver 17 run be moved on. So it becomes the lower roller 4 in the previously taken up 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 8th offset, the carriage 7 remains free. Where appropriate the distances of sections 8 and 9 to the fixed position to adapt the new output lower roller 4 in the punch 6. The upper rollers 10 are correspondingly in the roller holder 22 to move the corresponding handlebar 20. From Fig. 3 are the new positions of the lower rollers, the upper rollers, the lower aprons and the top strap based on the assigned to them Reference numbers recognizable. Because the previous Delivery roller pair 4/10 in place of the previous output roller pair 5/13 is the same length again and are again the same run-off angles of the thread 26 given as with compression function. Since the roving leader 23 expediently remains in its position, advantageously remains also the feed of the roving 25 unchanged.

Aus Fig. 4 ist erkennbar, daß anstelle der Ausgangsunterwalze 5 auch die Zwischenunterwalze 4 entnommen werden kann. Die Ausgangsunterwalze 5 bleibt dabei in ihrer Position, die anderen Arbeitsorgane des Streckwerkes rücken um jeweils eine Position in Richtung des Laufes der Faserlunte 17 weiter. From Fig. 4 it can be seen that instead of the output lower roller 5 the intermediate lower roller 4 can also be removed. The Output lower roller 5 remains in position, the others Working elements of the drafting system move by one Position in the direction of the run of the sliver 17 further.

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 Unterwalze 5 bzw. 4 eingesetzt werden.When changing the drafting system 1 to the compression function Conversely, the drafting rollers have to be reversed as described above with stretching function against the material direction moved to the rear and the compression unit 19 and the lower roller 5 and 4 are used.

Es versteht sich, daß das erfindungsgemäße Entnehmen des Verdichtungsaggregates und das Nachrücken der verbleibenden Streckwalzen auch bei Streckwerken mit Verdichtungsaggregaten anderer Bauart ausführbar ist und der Schutz sich demgemäß nicht auf Streckwerke mit pneumatischen Verdichtungsaggregaten wie vorstehend beschrieben beschränkt. It is understood that the removal of the compression unit according to the invention and moving up the remaining Drafting rollers also in drafting units with compaction units other design is feasible and the protection accordingly not on drafting systems with pneumatic compaction units limited as described above.
