Description

Die Erfindung bezieht sich auf ein Streckwerk in einer Textilmaschine, mit einem antreibbaren Auslaufzylinder, der in einem Maschinengestell feststehend gelagert ist, und mit einem antreibbaren Einlaufzylinder und wenigstens einem antreibbaren Zwischenzylinder, die je ein Antriebsrad tragen und in einem Rahmen gelagert sind, welcher im Maschinengestell gegenüber dem Auslaufzylinder verstellbar und mit lösbaren Feststellelementen fixierbar ist, wobei wenigstens ein Antriebsband, an welchem eine Spannrolle anliegt, um wenigstens eines der Antriebsräder und um ein antreibbares Rad gelegt ist.The invention relates to a drafting system in a textile machine, with a drivable outlet cylinder which is fixedly mounted in a machine frame, and with a drivable inlet cylinder and at least one drivable intermediate cylinder, each of which carries a drive wheel and is mounted in a frame which is in the machine frame is adjustable relative to the outlet cylinder and can be fixed with releasable locking elements, at least one drive belt, against which a tensioning roller rests, being placed around at least one of the drive wheels and around a drivable wheel.

Solche Streckwerke werden insbesondere in Kämmaschinen verwendet. Der dem Auslaufzylinder unmittelbar benachbarte Zwischenzylinder ist mit dem Rahmen, in dem er gelagert ist, bezüglich des Auslaufzylinders etwa radial verstellbar, damit der Abstand zwischen der Klemmlinie auf diesem Zwischenzylinder und der Klemmlinie auf dem Auslaufzylinder in Anpassung an den Stapel des zu verziehenden Fasermaterials optimal eingestellt werden kann.Such drafting systems are used in particular in combing machines. The intermediate cylinder immediately adjacent to the outlet cylinder is approximately radially adjustable with respect to the outlet cylinder with the frame in which it is mounted, so that the distance between the clamping line on this intermediate cylinder and the clamping line on the outlet cylinder is optimally adjusted to match the stack of the fiber material to be warped can be.

In einem bekannten Streckwerk der angegebenen Art (US-A-3 858 278) ist das antreibbare Rad in dem verstellbaren Rahmen gelagert und wird seinerseits über einen Zahnriemen von einem im Maschinengestell gelagerten Motor aus angetrieben. Die Auswirkung von Verstellungen des Rahmens auf den Zahnriemen sollen von einer an diesem anliegenden federbelasteten Spannrolle kompensiert werden.In a known drafting arrangement of the specified type (US-A-3 858 278), the drivable wheel is mounted in the adjustable frame and is in turn driven by a motor mounted in the machine frame via a toothed belt. The effect of adjustments of the frame on the toothed belt is to be compensated for by a spring-loaded tensioning roller resting against it.

In anderen aus der Praxis bekannten Streckwerken werden der Einlaufzylinder und die Zwischenzylinder über Zahnräder von einer im Maschinengestell gelagerten Welle aus angetrieben. Da die Verstellbarkeit dieser Zylinder und des Rahmens gewährleistet sein muss, sind die hierzu verwendeten Zahnradgetriebe kompliziert und teuer.In other drafting systems known from practice, the inlet cylinder and the intermediate cylinder are driven by gears from a shaft mounted in the machine frame. Since the adjustability of these cylinders and the frame must be ensured, the gearwheels used for this purpose are complicated and expensive.

Die Aufgabe der Erfindung besteht darin, in einem Streckwerk der eingangs angegebenen Art die Mittel zum Antreiben des Einlaufzylinders und des Zwischenzylinders bzw. der Zwischenzylinder im Vergleich mit bekannten Streckwerken einfacher und billiger auszubilden.The object of the invention is to provide the means for driving the inlet cylinder and the intermediate cylinder in a drafting system of the type specified at the outset or to make the intermediate cylinder simpler and cheaper in comparison with known drafting systems.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass das antreibbare Rad im Maschinengestell gelagert ist, dass die Spannrolle für das Antriebsband auf einem bewegbaren Träger gelagert ist und dass eines der Feststellelemente dazu eingerichtet ist, den Rahmen, den bewegbaren Träger und das Maschinengestell in Bezug aufeinander zu fixieren.The object is achieved according to the invention in that the drivable wheel is mounted in the machine frame, that the tensioning roller for the drive belt is mounted on a movable carrier and that one of the locking elements is set up to move the frame, the movable carrier and the machine frame in relation to one another fix.

Durch das genannte Feststellelement, welches den Rahmen, den bewegbaren Träger und das Maschinengestell bezüglich einander fixiert, wird die Gefahr einer Ueberdehnung des Antriebsbandes und/oder einer Beschädigung der Lager der Zylinder beim Verstellen des Rahmens ausgeschlossen, denn ein solches Verstellen ist erst möglich, nachdem dieses Feststellelement gelöst worden ist und damit auch der Träger der Spannrolle freigegeben worden ist, so dass sich die Spannrolle frei verlagern kann.By said locking element, which fixes the frame, the movable support and the machine frame with respect to each other, the risk of overstretching the drive belt and / or damage to the bearings of the cylinders when adjusting the frame is excluded, because such adjustment is only possible after this locking element has been released and thus the carrier of the tensioning pulley has been released so that the tensioning pulley can move freely.

Das Antriebsband ist vorzugsweise ein Zahnriemen. Es könnte aber auch beispielsweise eine Kette oder ein Flachriemen sein. Die Antriebsräder der Zylinder und das im Maschinengestell gelagerte antreibbare Rad wären natürlich entsprechend anzupassen.The drive belt is preferably a toothed belt. However, it could also be a chain or a flat belt, for example. The drive wheels of the cylinders and the drivable wheel mounted in the machine frame would of course have to be adapted accordingly.

Ein Ausführungsbeispiel des erfindungsgemässen Streckwerks wird nachstehend anhand der Zeichnungen näher erläutert. In diesen zeigen:

  • Fig. 1 einen schematischen Vertikalschnitt durch die Zylinder eines erfindungsgemässen Streckwerks,
  • Fig. 2 eine Draufsicht zu Fig. 1,
  • Fig. 3 eine Vorderansicht des Streckwerks und
  • Fig. 4 eine Rückansicht des Streckwerks.
An embodiment of the drafting system according to the invention is explained in more detail below with reference to the drawings. In these show:
  • 1 shows a schematic vertical section through the cylinders of a drafting system according to the invention,
  • 2 is a plan view of FIG. 1,
  • Fig. 3 is a front view of the drafting system and
  • Fig. 4 is a rear view of the drafting system.

Das schematisch dargestellte Streckwerk enthält einen antreibbaren Auslaufzylinder 1, der in einem Maschinengestell 2 einer Textilmaschine, insbesondere einer Kämmaschine, gelagert ist. Mit dem Auslaufzylinder 1 wirkt eine Auslaufdruckwalze 3 zusammen, die im Betrieb durch nicht dargestellte Belastungsmittel nach unten gegen den Auslaufzylinder gedrückt wird.The drawing system shown schematically contains a drivable outlet cylinder 1, which is mounted in a machine frame 2 of a textile machine, in particular a combing machine. An outlet pressure roller 3 interacts with the outlet cylinder 1 and is pressed downward against the outlet cylinder during operation by loading means (not shown).

Weiter enthält das Streckwerk einen Einlaufzylinder 4 und drei Zwischenzylinder 5, 6 und 7, die alle in einem Rahmen mit zwei Seitenplatten 8 und 9 drehbar gelagert sind. Der Rahmen 8, 9 ist im Maschinengestell 2 bezüglich des Auslaufzylinders 1 verschiebbar, z.B. mit Hilfe einer Einstellschraube 10, die sich durch eine Bohrung in einem Teil 2.1 des Maschinengestells 2 erstreckt und in eine Gewindebohrung in einem Querstab 11 des Rahmens 8, 9 geschraubt ist. An jeder Seite des Rahmens 8, 9 sind je zwei Feststellelemente angeordnet, mit denen der Rahmen in jeder eingestellten Lage bezüglich des Maschinengestells 2 fixiert werden kann. Die Feststellelemente haben beispielsweise die Form von Klemmschrauben 12 und 13 bzw. 14 und 15, die sich durch Langlöcher 16, 17, 18, 19 in den Rahmenseitenplatten 8 und 9 erstrecken und in Gewindebohrungen im Maschinengestell 2 geschraubt sind (Fig. 3, 4). Im Rahmen 8, 9 sind auch zwei Druckwalzen 20 und 21 (Fig. 1, 2) angeordnet, die im Betrieb durch nicht dargestellte Belastungseinrichtungen nach unten gegen die Zwischenzylinder 4 und 5 bzw. gegen die Zwischenzylinder 6 und 7 gedrückt werden.The drafting system also contains an inlet cylinder 4 and three intermediate cylinders 5, 6 and 7, all of which are rotatably mounted in a frame with two side plates 8 and 9. The frame 8, 9 is displaceable in the machine frame 2 with respect to the outlet cylinder 1, for example with the aid of an adjusting screw 10 which extends through a bore in part 2.1 of the machine frame 2 and is screwed into a threaded bore in a crossbar 11 of the frame 8, 9 . On each side of the frame 8, 9, two locking elements are arranged, with which the frame can be fixed in any set position with respect to the machine frame 2. The locking elements have, for example, the shape of clamping screws 12 and 13 or 14 and 15, which extend through elongated holes 16, 17, 18, 19 in the frame side plates 8 and 9 and are screwed into threaded bores in the machine frame 2 (FIGS. 3, 4) . In the frame 8, 9 there are also two pressure rollers 20 and 21 (FIGS. 1, 2) which are pressed down during operation by means of loading devices, not shown, against the intermediate cylinders 4 and 5 or against the intermediate cylinders 6 and 7.

Ein Antriebsband in Form eines Zahnriemens 22 läuft auf der Aussenseite der Rahmenseitenplatte 8 um Antriebszahnräder 23 und 24, die von den Zwischenzylindern 6 bzw. 7 getragen sind, und um ein Zahnrad 25, das auf einer im Maschinengestell 2 gelagerten, antreibbaren Welle 26 sitzt. Mit dem Zahnriemen 22 steht eine Spannrolle 27 in Berührung. Diese ist auf einem Träger 28 drehbar gelagert, der um eine Achse 29 schwenkbar am Maschinengestell 2 gelagert ist. Die Klemmschraube 13 erstreckt sich nicht nur durch das Langloch 17 in der Rahmenseitenplatte 8, sondern auch durch ein Langloch 30 im Träger 28. Damit dient die Klemmschraube 13 dazu, den schwenkbaren Träger 28, die verschiebbare Rahmenseitenplatte 8 und das Maschinengestell 2 in Bezug aufeinander zu fixieren.A drive belt in the form of a toothed belt 22 runs on the outside of the frame side plate 8 around drive toothed wheels 23 and 24, which are supported by the intermediate cylinders 6 and 7, and around a toothed wheel 25, which is seated on a drivable shaft 26 mounted in the machine frame 2. A tension roller 27 is in contact with the toothed belt 22. This is rotatably mounted on a carrier 28 which is pivotally mounted on the machine frame 2 about an axis 29. The clamping screw 13 extends not only through the elongated hole 17 in the frame side plate 8, but also through an elongated hole 30 in the carrier 28. Thus, the clamping screw 13 serves to pivot the carrier 28, the displaceable frame side plate 8 and the machine frame 2 with respect to one another fix.

Ein zweiter Zahnriemen 32 läuft auf der Aussenseite der Rahmenseitenplatte 9 um Antriebszahnräder 33 und 34, die von den Zwischenzylindern 4 bzw. 5 getragen sind, und um ein Zahnrad 35, das ebenfalls auf der antreibbaren Welle 26 sitzt. Mit dem Zahnriemen 32 steht eine Spannrolle 37 in Berührung. Diese ist auf einem Träger 38 drehbar gelagert, der um eine Achse 39 schwenkbar an der Rahmenseitenplatte 9 gelagert ist. Die Klemmschraube 15 erstreckt sich nicht nur durch das Langloch 19 in der Rahmenseitenplatte 9, sondern auch durch ein Langloch 40 im Träger 38.A second toothed belt 32 runs on the outside of the frame side plate 9 around drive toothed wheels 33 and 34, which are carried by the intermediate cylinders 4 and 5, and around a toothed wheel 35, which is also seated on the drivable shaft 26. A tensioning roller 37 is in contact with the toothed belt 32. This is rotatably mounted on a carrier 38 which is pivotally mounted on the frame side plate 9 about an axis 39. The clamping screw 15 extends not only through the elongated hole 19 in the frame side plate 9, but also through an elongated hole 40 in the carrier 38.

Wenn der Rahmen 8, 9 bezüglich des Maschinengestells 2 in Richtung zum Auslaufzylinder 1 hin oder von diesem weg verschoben werden soll, müssen zuerst die Klemmschrauben 12, 13, 14 und 15 gelöst werden. Damit werden auch die Träger 28 und 38 der Spannrollen 27 und 37 freigegeben. Beim Verschieben des Rahmens 8, 9 können die Spannrollen 27 und 37, da sie auf den frei schwenkbaren Trägern 28 bzw. 38 gelagert sind, keine übermässigen Spannungen in den Zahnriemen 22 und 32 bewirken.If the frame 8, 9 is to be displaced with respect to the machine frame 2 in the direction of the outlet cylinder 1 or away from it, the clamping screws 12, 13, 14 and 15 must first be loosened. This also releases the carriers 28 and 38 of the tensioning rollers 27 and 37. When moving the frame 8, 9, the tensioning rollers 27 and 37, since they are mounted on the freely pivotable supports 28 and 38, cannot cause excessive tension in the toothed belts 22 and 32.

Nach dem Verschieben des Rahmens 8, 9 werden zuerst die Klemmschrauben 12 und 14 wieder festgezogen. Dann werden die Träger 28 und 38 von Hand in Lagen geschwenkt, in denen die Spannrollen 27 und 37 die Zahnriemen 22 und 32 im gewünschten Mass gespannt halten. Anschliessend werden auch die Klemmschrauben 13 und 15 wieder festgezogen, um die Lagen der Träger 28 und 38 zu fixieren.After moving the frame 8, 9, the clamping screws 12 and 14 are tightened again. Then the carriers 28 and 38 are pivoted by hand into positions in which the tensioning rollers 27 and 37 keep the toothed belts 22 and 32 tensioned to the desired extent. The clamping screws 13 and 15 are then also tightened again in order to fix the positions of the supports 28 and 38.
