Abstract

The ring spinning or twisting machine possesses a mechanical coupling between the ring frame 3 and the fixing sleeve 11, thus allowing an accurate control of the fixing sleeve 11 for its displacement between the working position and open position. The coupling is formed by a drag lever 27, which acts on a driver part 18 of the fixing sleeve 11, and is effective as soon as the ring frame 3 descends into the lower winding position, the result of this being that the fixing sleeve assumes the open position. <IMAGE>

Description

Die vorliegende Erfindung betrifft eine Ringspinn- oder Zwirnmaschine gemäss Oberbegriff von Anspruch 1.The present invention relates to a ring spinning or twisting machine according to the preamble of claim 1.

Bei Maschinen der genannten Art dient die Festlegehülse dazu, den Faden maschinenseitig an der Spindelwelle festzulegen, was erlaubt, den frisch gesponnenen Kops zu doffen:In machines of the type mentioned, the fixing sleeve serves to fix the thread on the machine side on the spindle shaft, which allows the freshly spun bobbin to be doffed:

Ein Spinnvorgang, während dessen ein Kops aufgebaut wird, wird durch die Phase des Abspinnens abgeschlossen. Während des Abspinnens wird die Ober-, Hinter- und die Unterwindung ausgeführt. Die Unterwindung entsteht, sobald der Faden über die Unterwindkrone hinaus auf den darunterliegenden Spindelwellenabschnitt geführt wird, was voraussetzt, dass die Festlegehülse sich in Offenstellung befindet. Andernfalls würde die Unterwindung auf die Festlegehülse aufgebracht. Sobald die Unterwindung vorliegt, muss die Festlegehülse ihre Arbeitsstellung einnehmen, was bedeutet, dass sie durch Anpressen des Fadens an die Unterseite der Unterwindkrone den in der Unterwindung liegenden Fadenabschnitt und damit den Faden überhaupt festlegt. Wird nun beim anschliessenden Doffen der Kops entfernt, reisst der in der Unterwindung festgelegte Faden an der Unterwindkrone. Ein neuer Kops kann nun frisch angesponnen werden; dafür muss der Faden noch festgelegt bleiben. Sobald der Kops gefüllt ist, beginnt der Zyklus von neuem.A spinning process, during which a cop is built, is completed by the spinning phase. The upper, rear and underwinding are carried out during spinning. The underwinding arises as soon as the thread is guided beyond the underwind crown to the underlying spindle shaft section, which presupposes that the fixing sleeve is in the open position. Otherwise the underwinding would be applied to the fixing sleeve. As soon as the underwinding is present, the fixing sleeve must take up its working position, which means that by pressing the thread against the underside of the underwind crown, it fixes the thread section lying in the underwinding and thus the thread at all. If the cop is removed during the subsequent doffing, the thread defined in the underwinding tears at the underwind crown. A new cop can now be freshly spun on; the thread still has to be fixed. As soon as the cop is filled, the cycle starts again.

EPA 0 292 852 zeigt nun eine Spinneinheit für eine Ringspinnmaschine, deren Spindelwelle mit einer Unterwindkrone versehen ist, und eine relativ zur Unterwindkrone auf der Welle axial verschiebbare Festlegehülse. In einer an die Unterwindkrone anschlagenden Position der Festlegehülse wird der Faden festgelegt, während in einer von der Unterwindkrone entfernten Position der Faden in die Unterwindung gelegt bzw aus ihr entfernt werden kann.EPA 0 292 852 now shows a spinning unit for a ring spinning machine, the spindle shaft of which is provided with an underwind crown, and a fixing sleeve which is axially displaceable on the shaft relative to the underwind crown. The thread is fixed in a position of the fixing sleeve striking the underwind crown, while in in a position distant from the underwind crown, the thread can be placed in or removed from the underwinding.

Die Festlegehülse ist in ihrem unteren, d.h. von der Unterwindkrone entfernten Teil derart ausgebildet, dass sie sich während der Rotation der Spindelwelle durch die dann herrschende Zentrifugalkraft aufspreizen kann. Der spreizbare Teil greift in ein auf der Spindelwelle festsitzendes, im wesentlichen rotationssymmetrisches Steuerorgan für die Festlegehülse ein. Dabei sind der spreizbare Teil der Festlegehülse und der mit ihm im Eingriff stehende Bereich des Steuerorgans gegenseitig derart ausgebildet, dass sich die Festlegehülse durch die rotationsbedingte Aufspreizung nach unten, mithin in ihre Offenstellung bewegen muss, während sie sich durch die beim Stillstand der Spindelwelle gegebene Rückverformung nach oben in Schliess-, dh Arbeitsstellung abstösst.The fixing sleeve is in its lower, i.e. part removed from the underwind crown in such a way that it can expand during the rotation of the spindle shaft by the then prevailing centrifugal force. The expandable part engages in an essentially rotationally symmetrical control element for the fixing sleeve which is stuck on the spindle shaft. The expandable part of the fixing sleeve and the area of the control member which is in engagement with it are mutually designed such that the fixing sleeve must move downward, due to the rotation-related spreading, into its open position, while moving through the reshaping given when the spindle shaft is at a standstill pushes upwards in the closing, ie working position.

Dieser Anordnung ist aber unter anderem nachteilig, dass sie einerseits derart auszulegen ist, dass die Klemmung des Fadens während der vergleichsweise langsamen, für das Anspinnen zulässigen Spindelwellenrotation vorliegt. Andererseits aber muss die Festlegehülse während des ebenfalls bei langsamer Spindelwellenrotation erfolgenden Ausbildens der Unterwindung zuverlässig in Offenstellung gehalten werden. Diese beiden Kriterien sind gegenläufig; mit nur einem Steuerorgan können nicht beide Kriterien in der wünschbaren Weise realisiert werden.However, this arrangement is disadvantageous, inter alia, that on the one hand it is to be designed in such a way that the thread is clamped during the comparatively slow spindle shaft rotation permissible for piecing. On the other hand, however, the fixing sleeve must be held reliably in the open position while the underwinding is also being formed when the spindle shaft rotation is slow. These two criteria are contradictory; with only one control body, both criteria cannot be realized in the desired way.

Ferner besteht die Tendenz, in der Unterwindung Umschlingungswinkel von unter 3600 zu realisieren, mit der Konsequenz, dass im Hinblick auf einen präzisen Stopp der Spindelwelle deren Drehzahl schon während des Unterwindens gegen Null gefahren werden muss. Dies wiederum erschwert den Einsatz des oben beschriebenen Steuerorgans ausserordentlich, da bei der für die Unterwindung notwendigen Auslegung die Festlegung des Fadens beim Anspinnen nicht gewährleistet ist.Furthermore, there is a tendency to realize in underwinding wrap angle of less than 360 0, with the consequence that in terms of a precise stop the spindle shaft whose speed must be already driven during the sub overcoming zero. This in turn makes it extremely difficult to use the control element described above, since it is the one necessary for the submission Interpretation the definition of the thread during piecing is not guaranteed.

Entsprechend ist es Aufgabe der vorliegenden Erfindung, diese Nachteile zu überwinden und eine Ringspinn- oder Zwirnmaschine mit einwandfrei arbeitender Festlegehülse zu schaffen.Accordingly, it is an object of the present invention to overcome these disadvantages and to create a ring spinning or twisting machine with a properly functioning fixing sleeve.

Zur Lösung dieser Aufgabe besitzt die erfindungsgemässe Ringspinn- oder Zwirnmaschine die kennzeichnenden Merkmale nach Anspruch 1.To achieve this object, the ring spinning or twisting machine according to the invention has the characterizing features of claim 1.

Durch diese Merkmale wird erreicht, dass die Bewegung der Festlegehülse vom Ringrahmen beeinflusst, mithin ansteuerbar ist.These features ensure that the movement of the fixing sleeve is influenced by the ring frame and can therefore be controlled.

Der Ringrahmen führt die für Anspinnen, Spinnen und Abspinnen jeweils notwendigen Bewegungen aus. Insbesondere beim Anspinnen nimmt er eine Position oberhalb und beim Abspinnen, bzw. beim Anlegen der Unterwindung, eine Position unterhalb der Unterwindkrone ein. Somit kann der Position des Ringrahmens eine eindeutige Information betreffend der notwendigen Stellung der Festlegehülse entnommen werden: Senkt sich die Ringbank in Unterwindstellung, muss die Festlegehülse für das Anlegen der Unterwindung in Offenstellung gehalten sein; in den übrigen Positionen des Ringrahmens ist die Festlegehülse geschlossen zu halten, was sicherstellt, dass der Faden während dem Anspinnen festgelegt bleibt.The ring frame carries out the necessary movements for piecing, spinning and spinning. In particular when spinning it takes up a position above and when spinning, or when applying the underwinding, a position below the underwind crown. This means that the position of the ring frame provides clear information regarding the necessary position of the fixing sleeve: If the ring bench lowers in the downwind position, the fixing sleeve must be kept in the open position for the application of the winding. In the other positions of the ring frame, the fixing sleeve must be kept closed, which ensures that the thread remains fixed during the piecing.

Eine bevorzugte Ausführungsform nach Anspruch 6 sieht vor, dass der Ringrahmen über einen Wirkabschnitt auf eine Anschlagfläche der Festleghülse einwirkt und damit die Festlegehülse für die Unterwindung in Offenstellung drückt. Dadurch wird über die gestellte Aufgabe hinaus erreicht, dass Antrieb und Ansteuerung der Festlegehülse durch eine äusserst einfache und robuste Konstruktion realisiert werden können, so dass ein separater Antrieb für die Festlegehülse und aufwendige Regelung entfallen.A preferred embodiment according to claim 6 provides that the ring frame acts via an effective section on a stop surface of the fixing sleeve and thus presses the fixing sleeve for the winding in the open position. In addition to the task at hand, this ensures that the fixing sleeve is driven and controlled by an extremely simple and robust construction can be realized, so that a separate drive for the fixing sleeve and complex control are eliminated.

Nachstehend wird ein bevorzugtes Ausführungsbeispiel anhand der Figuren näher beschrieben.A preferred exemplary embodiment is described in more detail below with reference to the figures.

Es zeigt:
Fig 1 schematisch einen Teil eines Querschnitts durch die erfindungsgemässe Ringspinn- oder Zwirnmaschine; dargestellt ist der Bereich einer Spinneinheit der Maschine.It shows:
1 schematically shows a part of a cross section through the ring spinning or twisting machine according to the invention; the area of a spinning unit of the machine is shown.

In der Figur ist eine Spinneinheit 1, ein Rahmen 2, ein Ringrahmen 3 und eine Spindelwelle 4 mit einem Wirtel 5 einer Ringspinn- oder Zwirnmaschine dargestellt. Zur Entlastung der Figur weggelassen sind die im Rahmen 2 vorgesehenen Bereiche der Spindelwellenlagerung und der Lagerung des Ringrahmens 3.The figure shows a spinning unit 1, a frame 2, a ring frame 3 and a spindle shaft 4 with a whorl 5 of a ring spinning or twisting machine. To relieve the figure, the areas of the spindle shaft bearing and the bearing of the ring frame 3 provided in the frame 2 are omitted.

Die Figur zeigt weiter eine umlaufende Schulter 7 am oberen Ende der Spindelwelle 4, auf welche eine Hülse 8 eines Kops 9 aufgesetzt ist. Unterhalb der Hülse 8 befindet sich eine fest auf der Spindelwelle 4 angeordnete Unterwindkrone 10 und unter dieser wiederum eine Festlegehülse 11.The figure further shows a circumferential shoulder 7 at the upper end of the spindle shaft 4, on which a sleeve 8 of a cop 9 is placed. Underneath the sleeve 8 there is an underwind crown 10 which is fixedly arranged on the spindle shaft 4 and, under this in turn, a fixing sleeve 11.

Der Wirtel 5 besitzt eine bombierte Fläche 12 für einen Spindelwellentriebsriemen 13 und eine rohrförmig den Fuss der Spindelwelle 4 umfassende Spindelwellenhalterung 14.The whorl 5 has a cambered surface 12 for a spindle shaft drive belt 13 and a spindle shaft holder 14 which surrounds the base of the spindle shaft 4 in a tubular shape.

Die Festlegehülse 11 ist gegenüber der Spindelwelle 4 axialverschieblich auf der Spindelwellenhalterung 14 des Wirtels 5 gehalten. Weiter ist sie an der Spindelwelle 4 über einen gegen innen vorkragenden Flansch 15 abgestützt. Der Flansch 15 begrenzt zugleich den Verschiebungsbereich der Festlegehülse 11, indem er in deren oberster Stellung über eine Festlegefläche 16 gegen die Unterwindkrone 10 anstösst und in deren unterster Stellung über eine Stoppfläche 17 gegen die Spindelwellenhalterung 14 anschlägt.The fixing sleeve 11 is held axially displaceably on the spindle shaft holder 14 of the whorl 5 with respect to the spindle shaft 4. It is also supported on the spindle shaft 4 by a flange 15 projecting towards the inside. The flange 15 also limits the range of displacement of the fixing sleeve 11 by in whose uppermost position abuts against the underwind crown 10 via a fastening surface 16 and strikes against the spindle shaft holder 14 in its lowest position via a stop surface 17.

Ein mindestens in Richtung des Ringrahmens 3 radial von der Festlegehülse 10 vorspringender Mitnehmerteil 18 der Hülse 11 besitzt eine Anschlagfläche 19, über welche auf den Mitnehmerteil 18 und damit auf die Hülse 11 selbst eingewirkt werden kann.A driver part 18 of the sleeve 11 projecting radially at least in the direction of the ring frame 3 radially from the fixing sleeve 10 has a stop surface 19, via which the driver part 18 and thus the sleeve 11 itself can be acted on.

Der Ringrahmen 3 ist am Rahmen 2 vertikal beweglich gelagert und zwischen einer oberhalb der Oberkante der Hülse 8 liegenden oberen Endlage und einer unterhalb Unterwindkrone 10 liegenden unteren Endlage hin und her verschiebbar. Er trägt am Ort der ihm zugeordneten Spinneinheiten jeweils einen Spinnring 25 mit einem Läufer 26. Weiter ist am Ringrahmen 3 ein als Schlepphebel 27 ausgebildeter Wirkabschnitt angeformt, welcher sich in kraftschlüssiger Verbindung mit der Anschlagfläche 19 des Mitnehmerteils 18 befindet, somit eine mechanische Kopplung des Ringrahmens 3 mit der Festlegehülse 10 ausbildet. Die Wirkrichtung dieser Kopplung läuft parallel zur Längsachse der Spindelwelle 4 gegen den Wirtel 5, dh gegen unten.The ring frame 3 is mounted on the frame 2 so as to be vertically movable and can be moved back and forth between an upper end position above the upper edge of the sleeve 8 and a lower end position below the underwind crown 10. It carries a spinning ring 25 with a rotor 26 at the location of the spinning units assigned to it. Furthermore, an active section designed as a rocker arm 27 is formed on the ring frame 3, which is in a non-positive connection with the stop surface 19 of the driving part 18, thus a mechanical coupling of the ring frame 3 trained with the fixing sleeve 10. The direction of action of this coupling runs parallel to the longitudinal axis of the spindle shaft 4 against the whorl 5, ie towards the bottom.

Eine Feder 30 ist zwischen dem Schulterabschnitt 15 der Festlegehülse 10 und der Spindelwellenhalterung 14 eingespannt, derart, dass sie auf die Festlegehülse eine Kraft entgegen der Wirkrichtung der Kopplung bzw kraftschlüssigen Verbindung vom Ringrahmen 3 und der Hülse 10 ausübt.A spring 30 is clamped between the shoulder section 15 of the fixing sleeve 10 and the spindle shaft holder 14 in such a way that it exerts a force on the fixing sleeve against the direction of action of the coupling or non-positive connection between the ring frame 3 and the sleeve 10.

Sobald im Betrieb der Ringspinn- oder Zwirnmaschine das Abspinnen eingeleitet ist, senkt sich der Ringrahmen 3 aus seiner obern Endlage gegen die Unterwindkrone 10 ab, wodurch auf dem frisch gefüllten Kops 9 die Hinterwindung entsteht. Bevor nun der Läufer 26 während des weiteren Absenken des Ringrahmens 3 die Höhe der Unterwindkrone 11 erreicht, stösst der Schlepphebel 27 gegen die Anschlagfläche 19 des Mitnehmerteils 18, mit der Konseqenz, dass die Festlegehülse gegen den Druck der Feder 30 aus ihrer Arbeits- bzw Schliesstellung in Offenstellung gedrückt wird. Mithin ergibt sich, dass die Festlegehülse 10 bereits in einer Offenstellung liegt, sobald der Läufer in den Bereich unterhalb der Unterwindkrone 11 gelangt, was sicherstellt, dass die Unterwindung störungsfrei, insbesondere unabhängig von der Spindelwellendrehzahl erstellt werden kann.As soon as spinning is initiated during operation of the ring spinning or twisting machine, the ring frame 3 lowers from its upper end position against the underwind crown 10, as a result of which the rear winding is formed on the freshly filled cop 9. Before the runner 26 the height of the underwind crown during the further lowering of the ring frame 3 11 reached, the rocker arm 27 pushes against the stop surface 19 of the driver part 18, with the consequence that the fixing sleeve is pressed against the pressure of the spring 30 from its working or closed position into the open position. It thus follows that the fixing sleeve 10 is already in an open position as soon as the rotor reaches the area below the underwind crown 11, which ensures that the underwinding can be created without problems, in particular independently of the spindle shaft speed.

Sobald die Unterwindung fertiggestellt ist, hebt sich der Ringrahmen 3 wieder an, worauf der Faden aus der Unterwindung durch die Unterwindkorne zurück nach oben verläuft. Gleichzeitig gelangt die Festlegehülse (11) durch den Druck der Feder 30 in Arbeitsstellung, so dass der in der Unterwindung liegende Fadenabschnitt zwischen der Festlegefläche 16 und der Unterwindkrone 11 für das Doffen eingeklemmt wird.As soon as the underwinding is completed, the ring frame 3 lifts again, whereupon the thread from the underwinding runs back up through the underwinding beads. At the same time, the fixing sleeve (11) is brought into the working position by the pressure of the spring 30, so that the thread section lying in the underwinding is clamped between the fixing surface 16 and the underwind crown 11 for doffing.

Nach dem Doffen hebt sich der Ringrahmen 3 für das Anspinnen eines neuen Kops 9 weiter an, was bedeutet, dass sich spätestens in diesem Moment der Wirkabschnitt 27 vom Mitnehmerteil 18 löst. Der Faden bleibt aber durch den Druck der Feder 30 weiterhin festgelegt.After doffing, the ring frame 3 rises further for the spinning of a new cop 9, which means that the effective section 27 detaches from the driver part 18 at the latest at this moment. However, the thread remains fixed by the pressure of the spring 30.

Sobald der neue Kops 9 gefüllt ist, wiederholt sich der beschriebene Zyklus.As soon as the new cop 9 is filled, the cycle described is repeated.

Bei einem nicht in der Figur dargestellten Ausführungsbeispiel wirkt der Ringrahmen in zwei gegenläufigen Wirkrichtungen auf die Festlegehülse ein, so dass eine Feder 30 entfällt. Dadurch ergibt sich eine Zwangssteuerung der Festlegehülse durch den Ringrahmen.In an embodiment not shown in the figure, the ring frame acts in two opposite directions of action on the fixing sleeve, so that a spring 30 is omitted. This results in a forced control of the fixing sleeve by the ring frame.
