Abstract

The combing machine possesses a tearing-off device (11, 12, 13, 16) having a pair of tearing-off rollers (11, 12) for tearing off combed-out fibre tufts from a gripper (6, 7, 8, 9, 10) movable to and fro. A pair of soldering rollers (13, 16) for soldering the torn-off fibre tufts to form a combed fleece is arranged after the pair of tearing-off rollers (11, 12) in the tearing-off direction. The soldering rollers (13, 16) are designed to clamp the combed fleece only during part of each to-and-fro movement of the gripper (6, 7, 8, 9, 10). One of the tearing-off rollers (11) and one of the soldering rollers (13) are mounted fixedly relative to the stand in the combing machine and are driven continuously at a constant speed. Since virtually no parts rotating to and fro or moved to and fro are therefore needed in the tearing-off device (11, 12, 13, 16), high working speeds are possible. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Kämmaschine mit einer Abreissvorrichtung zum Abreissen von Faserbärten aus einer hin- und herbewegbaren Zange und Löte der abgerissenen Faserbärte zu einem Kammzugvlies welche Abreissvorrichtung ein kontinuierlich in Abreissrichtung drehbares Abreisswalzenpaar und ein in Abreissrichtung nach dem Abreisswalzenpaar angeordnetes Lötwalzenpaar besitzt.The invention relates to a combing machine with a tear-off device for tearing off fiber beards from a reciprocating pliers and soldering the torn off fiber beards to form a nonwoven web.

Eine solche Abreissvorrichtung, in der das Löten erst nach dem Abreisswalzenpaar erfolgt, z.B. wie in der US-A-1 922 030 beschrieben, hat den Vorteil, dass die Abreisswalzen kontinuierlich drehen können, das heisst, nicht mit einer Pilgerschrittbewegung hin- und hergedreht werden müssen. Dadurch sind höhere Arbeitsgeschwindigkeiten bzw. geringere Getriebebelastungen erzielbar. In der Abreissvorrichtung gemäss der genannten US-A-1 922 030 müssen jedoch die beiden Lötwalzen gemeinsam in Richtung zu den Abreisswalzen hin und von diesen weg hin- und herbewegt werden und gleichzeitig mit wechselnden Geschwindigkeiten gedreht werden.Such a tear-off device in which the soldering takes place only after the pair of tear-off rolls, e.g. as described in US-A-1 922 030 has the advantage that the tear-off rollers can rotate continuously, that is, do not have to be rotated back and forth with a pilgrim step movement. As a result, higher working speeds or lower gear loads can be achieved. In the tear-off device according to the aforementioned US-A-1 922 030, however, the two soldering rollers must be moved back and forth together towards and away from the tear-off rollers and simultaneously rotated at changing speeds.

Die Aufgabe der Erfindung besteht darin, in einer Kämmaschine der eingangs angegebenen Art die Abreissvorrichtung so auszubilden, dass Hin- und Herbewegungen in derselben möglichst weitgehend vermieden werden können. Gleichzeitig sollte ein einfacher Aufbau der Abreissvorrichtung und des Antriebes für dieselbe ermöglicht werden.The object of the invention is to design the tear-off device in a combing machine of the type specified at the outset in such a way that back and forth movements in it can be avoided as far as possible. At the same time, a simple structure of the tear-off device and the drive for the same should be made possible.

Die Aufgabe wird in der erfindungsgemässen Kämmaschine dadurch gelöst, dass die beiden Lötwalzen dazu eingerichtet sind, das Kammzugvlies nur während eines Teils jeder Hin- und Herbewegung der Zange festzuklemmen.The object is achieved in the combing machine according to the invention in that the two soldering rollers are set up to clamp the nonwoven web only during part of each reciprocating movement of the pliers.

Damit kann in einfacher Weise erreicht werden, dass die Lötwalzen das Kammzugvlies nur während des genannten Teils jeder Hin- und Herbewegung der Zange transportieren; es ist daher möglich, eine der Lötwalzen kontinuierlich mit konstanter Geschwindigkeit anzutreiben, wobei die Umfangsgeschwindigkeit dieser Lötwalze etwa gleich gross wie (oder wenig grösser als) die Umfangsgeschwindigkeit der Abreisswalzen ist. Mindestens eine der Lötwalzen, zweckmässig die angetriebene, kann gleich wie die Abreisswalzen im wesentlichen gestellfest gelagert sein.This can be achieved in a simple manner that the soldering rollers the comb web only during the mentioned Transport part of each reciprocation of the pliers; it is therefore possible to drive one of the soldering rollers continuously at a constant speed, the peripheral speed of this soldering roller being approximately the same size (or slightly greater than) the peripheral speed of the tear-off rollers. At least one of the soldering rollers, expediently the driven one, can, like the tear-off rollers, be mounted essentially fixed to the frame.

Ausführungsbeispiele der Erfindung werden nachstehend anhand der Zeichnung näher erläutert. In diesen zeigen:

  • Fig. 1 einen schematischen Vertikalschnitt durch Teile eines Kämmkopfes einer Kämmaschine,
  • Fig. 2 und Fig. 3 je eine ähnliche Ansicht wie der linke Teil von Fig. 1 bei jeweils anderen Stellungen der Teile des Kämmkopfes und
  • Fig. 4 eine andere Ausführungsmöglichkeit des Lötwalzenpaares des Kämmkopfes.
Embodiments of the invention are explained below with reference to the drawing. In these show:
  • 1 shows a schematic vertical section through parts of a combing head of a combing machine,
  • Fig. 2 and Fig. 3 each have a similar view as the left part of Fig. 1 at different positions of the parts of the combing head and
  • Fig. 4 shows another embodiment of the pair of soldering rollers of the combing head.

Die Kämmaschine gemäss Fig. 1 besitzt in üblicher Weise eine Rundkammwelle 1 und eine Zangenwelle 2, die je in einem nicht dargestellten Maschinengestell gelagert sind. Die Rundkammwelle 1, die im Betrieb der Kämmmaschine kontinuierlich mit konstanter Geschwindigkeit gedreht wird, trägt eine Rundkammwalze 3 mit einem mit Kämmnadeln oder Kämmgarnituren besetzten Rundkammsegment 4. Die Zangenwelle 2 wird hin- und hergeschwenkt, sie trägt Zangenarme 5, an welchen das hintere Ende eines Unterzangenrahmens 6 angelenkt ist. Das vordere Ende des Unterzangenrahmens 6 ist an Vorderstützen 7 angelenkt, die um die Achse der Rundkammwelle 1 schwenkbar sind. Der Unterzangenrahmen 6 trägt eine Unterzangenplatte 8, deren vorderer Rand mit dem unteren Rand einer Oberzangenplatte 9 zusammenwirkt, welche von bezüglich des Unterzangenrahmens 6 schwenkbaren Oberzangenarmen 10 gehalten ist.1 has in the usual way a round comb shaft 1 and a pliers shaft 2, each of which is mounted in a machine frame, not shown. The round comb shaft 1, which is rotated continuously at constant speed during operation of the combing machine, carries a round comb roller 3 with a round comb segment 4 equipped with combing needles or combing sets Crimping frame 6 is articulated. The front end of the collet frame 6 is articulated on front supports 7 which are pivotable about the axis of the round comb shaft 1. The lower clamp frame 6 carries a lower clamp plate 8, the front edge of which cooperates with the lower edge of a upper clamp plate 9, which is held by upper clamp arms 10 which can be pivoted with respect to the lower clamp frame 6.

Der Zange 6, 7, 8, 9, 10 wird zu kämmendes Fasermaterial in Form einer Watte W zugeführt. In Fig. 1 ist die Zange in einer zurückgezogenen, geschlossenen Stellung dargestellt, der vordere Endabschnitt der Watte W ist zwischen den Zangenplatten 8 und 9 festgeklemmt, und der aus der Zange heraus vorstehende Faserbart wird vom Rundkammsegment 4 ausgekämmt.The pliers 6, 7, 8, 9, 10 are fed fiber material to be combed in the form of a cotton wool W. In Fig. 1 the pliers is shown in a retracted, closed position, the front end portion of the wadding W is clamped between the pliers plates 8 and 9, and the fiber beard protruding from the pliers is combed out by the circular comb segment 4.

Danach wird die Zange 6, 7, 8, 9, 10 wie in den Fig. 2 und 3 gezeigt gegen eine vorgeschobene, geöffnete Stellung bei einer Abreissvorrichtung bewegt. Die Abreissvorrichtung enthält eine untere Abreisswalze 11, die in der Kämmaschine gestellfest gelagert ist und kontinuierlich mit konstanter Geschwindigkeit in Abreissrichtung gedreht wird, und eine obere Abreisswalze 12, die von einer Kraftbelastung gegen die untere Abreisswalze 11 gedrückt ist und von dieser mitgenommen wird. In Abreissrichtung nach den Abreisswalzen 11, 12 enthält die Abreissvorrichtung eine obere Lötwalze 13, die in der Kämmaschine gestellfest gelagert ist und ebenfalls kontinuierlich mit konstanter Geschwindigkeit in Abreissrichtung gedreht wird. Beispielsweise kann die obere Lötwalze 13 wie in Fig. 1 mit strich-punktierten Linien angedeutet durch Zahnräder 14 und 15 direkt mit der unteren Abreisswalze 11 gekuppelt sein. Mit der oberen Lötwalze 13 wirkt eine untere Lötwalze 16 zusammen, die in Hebeln 17 gelagert ist, welche um eine gestellfeste Achse 18 schwenkbar sind. Die Hebel 17 werden von einem nicht dargestellten Antrieb auf- und abgeschwenkt, so dass sie die untere Lötwalze 16 nur während eines Teils jeder Hin- und Herbewegung der Zange 6, 7, 8, 9, 10 gegen die obere Lötwalze 13 drücken, wie im Nachstehenden noch erläutert wird.The pliers 6, 7, 8, 9, 10 are then moved against an advanced, open position in a tear-off device, as shown in FIGS. 2 and 3. The tear-off device contains a lower tear-off roller 11 which is mounted on the frame in the combing machine and is rotated continuously at a constant speed in the tear-off direction, and an upper tear-off roller 12 which is pressed against the lower tear-off roller 11 by a load of force and is carried by the latter. In the tear-off direction after the tear-off rollers 11, 12, the tear-off device contains an upper soldering roller 13 which is mounted on the frame in the combing machine and is also rotated continuously at a constant speed in the tear-off direction. For example, the upper soldering roller 13, as indicated in FIG. 1 by dash-dotted lines, can be coupled directly to the lower tear-off roller 11 by gear wheels 14 and 15. A lower soldering roller 16 interacts with the upper soldering roller 13 and is mounted in levers 17 which can be pivoted about an axis 18 fixed to the frame. The levers 17 are pivoted up and down by a drive, not shown, so that they press the lower soldering roller 16 against the upper soldering roller 13 only during part of each reciprocating movement of the pliers 6, 7, 8, 9, 10, as in FIG The following will be explained.

In Fig. 3 hat die Zange 6, 7, 8, 9, 10 ihre vordere Endlage erreicht, das vordere Ende des zuvor vom Rundkammsegment 4 ausgekämmten Faserbartes wird von den Abreisswalzen 11, 12 erfasst. Die Abreisswalzen 11, 12 reissen dann den Faserbart von der in der Zange liegenden Watte W ab, wobei das hintere Ende des Faserbartes durch einen Fixkamm 19 hindurchgezogen und von diesem ausgekämmt wird.3, the pliers 6, 7, 8, 9, 10 have reached their front end position, the front end of the fiber beard previously combed by the circular comb segment 4 is gripped by the tear-off rollers 11, 12. The tear-off rollers 11, 12 then tear the fiber beard from that lying in the pliers Wadding off cotton wool, the rear end of the fiber beard being pulled through a fixed comb 19 and combed out by the latter.

Nachstehend wird erläutert, wie die Faserbärte, die von den kontinuierlich drehenden Abreisswalzen 11, 12 nacheinander aus der Zange abgerissen und in Abreissrichtung weitertransportiert werden, durch die Wirkung der Lötwalzen 13, 16 zu einem Kammzugvlies vereinigt werden. In Fig. 1 halten die Hebel 17 die untere Lötwalze 16 in einer unteren, von der oberen Lötwalze 13 entfernten Lage. Das Kammzugvlies, das auf der unteren Lötwalze 16 und auf einer ebenfalls von den Hebeln 17 getragenen Führungsplatte 20 liegt, wird daher nicht transportiert, obwohl die obere Lötwalze 13 kontinuierlich gedreht wird. Die untere Lötwalze 16 steht still. Das hintere Ende des Kammzugvlieses steht in einem Abstand hinter der Klemmlinie der Lötwalzen 13, 16. Gleichzeitig transportieren die Abreisswalzen 11, 12 einen Faserbart, der zuvor von der Watte W abgerissen worden ist.The following explains how the fiber whiskers, which are torn from the pliers one after the other by the continuously rotating tear-off rollers 11, 12 and transported further in the tear-off direction, are combined to form a comb-pulling fleece by the action of the soldering rollers 13, 16. In Fig. 1, the levers 17 hold the lower soldering roller 16 in a lower position away from the upper soldering roller 13. The crest fleece, which lies on the lower soldering roller 16 and on a guide plate 20 which is also carried by the levers 17, is therefore not transported, although the upper soldering roller 13 is rotated continuously. The lower soldering roller 16 stands still. The rear end of the roving fleece is at a distance behind the clamping line of the soldering rollers 13, 16. At the same time, the tear-off rollers 11, 12 transport a fiber beard which has previously been torn off the cotton wool W.

Wenn die Zange 6, 7, 8, 9, 10 danach die in Fig. 2 gezeigte Stellung erreicht und der von den Abreisswalzen 11, 12 transportierte Faserbart die Klemmlinie der Abreisswalzen verlässt und sich mit seinem vorderen Ende der Klemmlinie der Lötwalzen 13, 16 nähert, heben die Hebel 17 die untere Lötwalze 16 nach oben und drücken sie gegen die obere Lötwalze 13, so dass sich das vordere Ende des von den Abreisswalzen 11, 12 abgegebenen Faserbartes schuppenartig überlappend auf das hintere Ende des Kammzugvlieses legt und die obere Lötwalze 13 das Kammzugvlies in Abreissrichtung zu transportieren beginnt.When the pliers 6, 7, 8, 9, 10 then reach the position shown in FIG. 2 and the fiber beard transported by the tear-off rollers 11, 12 leaves the clamping line of the tear-off rollers and approaches the clamping line of the soldering rollers 13, 16 with its front end , the levers 17 lift the lower soldering roller 16 upwards and press them against the upper soldering roller 13, so that the front end of the fiber beard released by the tear-off rollers 11, 12 overlaps in a scaly manner on the rear end of the ridge fleece and the upper soldering roller 13 does so Kammzugvlies begins to transport in the tear-off direction.

In Fig. 3 ist das Kammzugvlies dann etwas weitertransportiert, das vordere Ende des zuletzt angefügten Faserbartes hat die Klemmlinie der Lötwalzen 13, 16 bereits passiert.In Fig. 3 the roving fleece is then transported somewhat further, the front end of the last added fiber beard has already passed the clamping line of the soldering rollers 13, 16.

Wenn dann das hintere Ende des zuletzt angefügten Faserbartes die in Fig. 1 gezeigte Stellung im Abstand hinter der Klemmlinie der Lötwalzen 13, 16 erreicht hat, senken die Hebel 17 die untere Klemmwalze 16 wieder, um das Kammzugvlies stillzusetzen, bis der nächste abgerissene Faserbart von den Abreisswalzen 11, 12 abgegeben wird.Then when the rear end of the last added fiber beard the position shown in Fig. 1 at a distance has reached behind the clamping line of the soldering rollers 13, 16, the levers 17 lower the lower clamping roller 16 again in order to stop the comb pulling fleece until the next torn fiber beard is released by the tear-off rollers 11, 12.

Die Fig. 4 zeigt eine andere Ausführungsform einer Abreissvorrichtung, die in dem Kämmkopf die beschriebenen Funktionen ausüben kann. Die Abreisswalzen 11, 12 sind gleich ausgebildet wie anhand der Fig. 1 bis 3 beschrieben, die Walze 11 ist im Betrieb kontinuierlich in Abreissrichtung angetrieben. Die untere Lötwalze besitzt einen gestellfest gelagerten, im Betrieb kontinuierlich in Abreissrichtung angetriebenen Walzenkörper 21, welcher drei voneinander getrennte Umfangssegmente 22 trägt. Jedes Umfangssegment 22 klemmt das Kammzugvlies nur während eines Teils einer Hin- und Herbewegung der Zange des Kämmkopfes gegen die obere Lötwalze 13, so dass das Kammzugvlies nur während dieses Teils der Zangenbewegung transportiert wird, wie anhand der Fig. 1 bis 3 beschrieben. Die Stellung gemäss Fig. 4 entspricht der Stellung gemäss Fig. 2, der Transport des Kammzugvlieses beginnt. Der Transport des Kammzugvlieses hört wieder auf, wenn das hintere Ende des Kammzugvlieses ähnlich wie in Fig. 1 im Abstand hinter der Klemmlinie der Lötwalzen 13 und 21, 22 steht, in diesem Moment verlässt das in Fig. 4 obere Umfangssegment 22 die obere Lötwalze 13.Fig. 4 shows another embodiment of a tear-off device which can perform the functions described in the combing head. The tear-off rollers 11, 12 are of the same design as described with reference to FIGS. 1 to 3, the roller 11 is driven continuously in the tear-off direction during operation. The lower soldering roller has a roller body 21 which is fixed to the frame and is continuously driven in the tear-off direction during operation and which carries three separate peripheral segments 22. Each circumferential segment 22 only clamps the comb web against the upper soldering roller 13 during part of a reciprocating movement of the pliers of the combing head, so that the comb web is only transported during this part of the pliers movement, as described with reference to FIGS. 1 to 3. The position according to FIG. 4 corresponds to the position according to FIG. 2, the transport of the ridge fleece begins. The transport of the crest fleece stops again when the rear end of the crest fleece is at a distance behind the clamping line of the soldering rollers 13 and 21, 22, as in FIG. 1, at this moment the upper peripheral segment 22 in FIG. 4 leaves the upper soldering roller 13 .
