Description

Die Erfindung betrifft eine Vorrichtung zum Abnehmen und Zusammenfassen eines aus einem Walzenpaar austretenden Faservlieses zu einem Faserband mit wenigstens einem endlosen Transportband, das mittels einer ersten und zweiten Umlenkrolle geführt ist und das Walzenpaar über seine Lieferbreite tangiert.The invention relates to a device for removing and combining a nonwoven fabric emerging from a pair of rollers to form a sliver with at least one endless conveyor belt, which is guided by means of a first and second deflecting roller and affects the pair of rollers over its delivery width.

Es ist bekannt, ein aus einem Lieferwalzenpaar austretendes Faservlies mittels eines Transportbandes, das das Lieferwalzenpaar über seine gesamte Lieferbreite tangiert und eine die Ebene des Faservlieses kreuzende Transportebene bildet, vom Lieferwalzenpaar abzunehmen und zu einem Faserband zusammenzufassen (DE-OS 1.912.452). Das Transportband wird über zwei ortsfest angeordnete Umlenkrollen geführt, von denen eine als Antriebsrolle dient (DE-OS 2.109.955). Anstelle nur eines Transportbandes können dem Lieferwalzenpaar auch wenigstens zwei gegeneinanderlaufende Transportbänder nachgeordnet sein, wobei jedes Transportband noch über eine dritte Umlenkrolle derart geführt sein kann, daß die beiden Transportbänder in Transportrichtung des Faserbandes im wesentlichen parallel laufen und dem Faserband eine zwangsläufige Führung bis in Nähe eines Abzugswalzenpaares geben.It is known to remove a nonwoven fabric emerging from a pair of delivery rollers by means of a conveyor belt which touches the pair of delivery rollers over its entire delivery width and forms a transport plane crossing the plane of the nonwoven web, and to combine them into a fiber band (DE-OS 1,912,452). The conveyor belt is guided over two stationary deflection rollers, one of which serves as a drive roller (DE-OS 2.109.955). Instead of just one conveyor belt, the delivery roller pair can also have at least two conveyor belts running in opposite directions, each conveyor belt being able to be guided via a third deflecting roller in such a way that the two conveyor belts run essentially parallel in the direction of transport of the sliver and the sliver is inevitably guided close to one Give the pair of draw rollers.

Das Lieferwalzenpaar ist bei Karden häufig ein aus zylindrischen Walzen bestehendes Quetschwalzenpaar, das die im Faservlies noch enthaltenen Blatt- und Schalenteile zermalmt. Um den auf die Oberwalze des Quetschwalzenpaares ausgeübten Anpreßdruck gleichmäßig über die Arbeitsbreite zu verteilen und eine faserschonende Wirkung zu erzielen, erfolgt eine Achsverschränkung der Walzen, deren Ausmaß von dem zur Verarbeitung kommenden Fasermaterial und der gewünschten Höhe des Anpreßdruckes abhängt (DE-PS 1.510.215). Die Herausnahme der Walzen aus ihrer achsparallelen Lage hat jedoch bei der bekannten Vorrichtung zur Folge, daß das Transportband seine tangentiale Anlage an den Walzen über deren Lieferbreite verliert. Dadurch kommt es zu Störungen beim Abnehmen und Zusammenfassen des aus dem Walzenpaar austretenden Faservlieses.In the case of cards, the delivery roller pair is often a pair of squeeze rollers consisting of cylindrical rollers, which crushes the sheet and shell parts still contained in the nonwoven fabric. In order to distribute the contact pressure exerted on the top roller of the pair of squeeze rollers evenly over the working width and to achieve a fiber-protecting effect, the rollers are axially crossed, the extent of which depends on the fiber material being processed and the desired amount of contact pressure depends (DE-PS 1.510.215). Removing the rollers from their axially parallel position, however, has the consequence in the known device that the conveyor belt loses its tangential contact with the rollers over their delivery width. This leads to disturbances when removing and combining the fiber fleece emerging from the pair of rollers.

Aufgabe der vorliegenden Erfindung ist es, diesen Nachteil zu vermeiden und ein ordnungsgemäßes Abnehmen und Zusammenfassen des Faservlieses auch bei einer Änderung der Lage der Walzen zueinander sicherzustellen.The object of the present invention is to avoid this disadvantage and to ensure proper removal and gathering of the nonwoven fabric even when the position of the rollers relative to one another changes.

Die Aufgabe wird bei einer Vorrichtung gemäß dem Oberbegriff des Anspruches 1 erfindungsgemäß dadurch gelöst, daß die Achse der Umlenkrollen einer geänderten Achslage der Walzen zueinander nachführbar gelagert ist, und daß das Transportband über eine von der Achsverbindungsebene der Umlenkrollen entfernt angeordnete Antriebsrolle geführt ist.The object is achieved according to the invention in a device according to the preamble of claim 1 in that the axis of the deflecting rollers of a changed axial position of the rollers is mounted such that they can be tracked relative to one another, and that the conveyor belt is guided over a drive roller arranged at a distance from the axis connecting plane of the deflecting rollers.

Dadurch kann das an den Walzen anlaufende Trum des Faserbandes mittels der Umlenkrollen in eine Lage gebracht werden, in der es nicht mehr in einer Ebene liegt, sondern so in sich verschränkt ist, daß es die beiden Walzen nach erfolgter Achsverschränkung über die Lieferbreite tangential berührt.As a result, the run of the fiber sliver running against the rollers can be brought into a position by means of the deflecting rollers in which it no longer lies in one plane, but is so entangled that it tangentially touches the two rollers after the axis has been locked over the delivery width.

In vorteilhafter Weiterbildung der Erfindung sind die Umlenkrollen auf einem Taumelbolzen gelagert. Dabei wird vorgesehen, daß der Schwenkpunkt des Taumelbolzens in Höhe der Mittelachse einer der beiden Walzen des Walzenpaares liegt, so daß die Achslage einer der Walzen geändert und die Lage des Transportbandes ihr angepaßt werden kann. Um die Lage des Transportbandes in Bezug auf die Umlenkrollen einstellen und korrigieren zu können, ist der Taumelbolzen in einer Lagerplatte drehbar angeordnet, die um eine senkrecht zur Längsachse der Walzen angeordnete Achse schwenkbar ist. Das Spannen des Transportbandes wird dadurch ermöglicht, daß die Achse in einer in Richtung der Längsachse der Walzen verschiebbaren Lagerplatte angeordnet ist. Dadurch, daß bei Verwendung von zwei Transportbändern die Antriebsrollen der Transportbänder in der gleichen Antriebsebene liegen, wird der Antrieb vereinfacht. Die Anordnung der Antriebsrollen unmittelbar nebeneinander stellt sicher, daß die in Transportrichtung des Faserbandes parallel zueinander geführten Transportbänder dem Faserband eine zwangsläufige Führung geben. Der Zugang zum Faserbandauslauf zwischen den Transportbändern wird dadurch erleichtert, daß die Antriebsrolle eines jeden Transportbandes von der Bewegungsbahn des Faserbandes entfernt angeordnet ist. Das Walzenpaar wird dadurch frei zugänglich, daß die Transportbänder samt ihrer Umlenk- und Antriebsrollen vom Walzenpaar wegbewegbar sind.In an advantageous development of the invention, the deflection rollers are mounted on a wobble pin. It is provided that the pivot point of the wobble bolt is at the height of the central axis of one of the two rollers of the pair of rollers, so that the axial position of one of the rollers can be changed and the position of the conveyor belt can be adapted to it. In order to be able to adjust and correct the position of the conveyor belt in relation to the deflection rollers, the wobble pin is rotatably arranged in a bearing plate which can be pivoted about an axis arranged perpendicular to the longitudinal axis of the rollers. The tensioning of the conveyor belt is made possible that the axis is arranged in a bearing plate displaceable in the direction of the longitudinal axis of the rollers. The fact that when using two conveyor belts, the drive rollers of the conveyor belts are in the same drive plane, the drive is simplified. The arrangement of the drive rollers directly next to one another ensures that the conveyor belts, which are parallel to one another in the transport direction of the sliver, give the sliver an inevitable guidance. Access to the sliver outlet between the conveyor belts is facilitated in that the drive roller of each conveyor belt is arranged away from the path of movement of the sliver. The pair of rollers is freely accessible in that the conveyor belts, including their deflection and drive rollers, can be moved away from the pair of rollers.

Den Figuren 1 und 4 ist ein Quetschwalzenpaar 1 mit einer Oberwalze 10 und einer Unterwalze 11 zu entnehmen, an dessen Lieferseite ein endloses Transportband 2 angeordnet ist. Das Transportband 2 ist über eine erste Umlenkrolle 3 und eine zweite Umlenkrolle 4 derart geführt, daß es die Oberwalze 10 und die Unterwalze 11 des Quetschwalzenpaares 1 tangential berührt. Von der Achsverbindungsebene A der Umlenkrollen 3 und 4 entfernt ist eine Antriebsrolle 5 angeordnet, die ihren Antrieb von einer Antriebswelle 50 aus über ein Kegelradgetriebe 51 erhält und das Transportband 2 in Richtung des Pfeiles P antreibt. Gegebenenfalls kann das Transportband 2 aber auch in entgegengesetzter Richtung angetrieben werden.FIGS. 1 and 4 show a pair of nip rollers 1 with an upper roller 10 and a lower roller 11, on the delivery side thereof an endless conveyor belt 2 is arranged. The conveyor belt 2 is guided over a first deflection roller 3 and a second deflection roller 4 in such a way that it tangentially contacts the top roller 10 and the bottom roller 11 of the pair of squeeze rollers 1. A drive roller 5, which receives its drive from a drive shaft 50 via a bevel gear 51 and drives the conveyor belt 2 in the direction of arrow P, is arranged from the axis connection plane A of the deflection rollers 3 and 4. If necessary, the conveyor belt 2 can also be driven in the opposite direction.

Die Umlenkrollen 3 und 4 sind derart verstellbar gelagert, daß ihre Achse einer geänderten Achslage der Walzen 10 und 11 zueinander nachgeführt werden kann. Die Verstellung erfolgt vorzugsweise mittels eines Taumelbolzens 6, auf dem die Umlenkrolle 3 und analog dazu die Umlenkrolle 4 gelagert sind (Figur 4). Der Taumelbolzen 6 ist an einem Maschinenteil 60 in einer Lagerplatte 61 drehbar angeordnet und erstreckt sich in eine Bohrung 30 der Umlenkrolle 3, in der er mittels einer Wälzlagerung 62 gelagert ist. Durch Verstellen des Taumelbolzens 6 nach Lösen einer Sicherungsschraube 63 kann die Achslage der Umlenkrollen 3 und 4 und damit die Lage des Transportbandes 2 der Achslage der beiden Walzen 10 und 11 angepaßt werden. Üblicherweise wird die Achse nur einer Walze verlagert. Der Schwenkpunkt des Taumelbolzens 6 wird daher in Höhe der Mittelachse einer der beiden Walzen 10 oder 11 angeordnet. In Figur 4 befindet sich der Schwenkpunkt S des Taumelbolzens 6 in Höhe der Mittelachse M der Oberwalze 10, so daß bei entsprechender Verstellung der Umlenkrollen 3 und 4 mittels des Taumelbolzens 6 das Transportband 2 einer Achsverlagerung der Unterwalze 11 folgen und beispielsweise in die gezeigte Schräglage gebracht werden kann, in der es wieder beide Walzen des Quetschwalzenpaares 1 tangential berührt.The deflection rollers 3 and 4 are adjustably mounted so that their axes can be adjusted to a changed axial position of the rollers 10 and 11 to each other. The adjustment is preferably carried out by means of a wobble pin 6 on which the deflection roller 3 and, analogously, the deflection roller 4 are mounted (FIG. 4). The wobble pin 6 is rotatably arranged on a machine part 60 in a bearing plate 61 and extends into a bore 30 of the deflection roller 3, in which it is mounted by means of a roller bearing 62. By adjusting the wobble pin 6 after loosening a locking screw 63, the axial position of the deflection rollers 3 and 4 and thus the position of the conveyor belt 2 can be adapted to the axial position of the two rollers 10 and 11. Usually, the axis of only one roller is moved. The pivot point of the wobble pin 6 is therefore arranged at the level of the central axis of one of the two rollers 10 or 11. In Figure 4, the pivot point S of the wobble pin 6 is at the height of the central axis M of the top roller 10, so that with appropriate adjustment of the deflection rollers 3 and 4 by means of the wobble pin 6, the conveyor belt 2 follow an axial displacement of the bottom roller 11 and, for example, brought into the inclined position shown can be in which it touches both rollers of the pair of squeeze rollers 1 tangentially.

Soll umgekehrt die Achslage nur der Oberwalze 10 geändert werden oder soll bei beiden Walzen eine Achsverschränkung erfolgen, so wird im ersten Fall der Schwenkpunkt des Taumelbolzens 6 in Höhe der Mittelachse der Unterwalze 11 und im zweiten Fall in Höhe der Klemmlinie zwischen den Walzen 10 und 11 angeordnet.Conversely, if the axis position of only the upper roller 10 is to be changed or if an axis is to be twisted on both rollers, the pivot point of the wobble pin 6 will be at a height in the first case the central axis of the lower roller 11 and in the second case at the level of the nip line between the rollers 10 and 11.

Um nach einer Änderung der Achslage der Umlenkrollen 3 und 4 ein Ablaufen des Transportbandes 2 von den Umlenkrollen zu verhindern, ist die Lagerplatte 61, in welcher der Taumelbolzen 6 angeordnet ist, um eine senkrecht zur Längsachse der Walzen 10, 11 verlaufende Achse 64 schwenkbar (Figur 5). Durch Drehen einer in die Lagerplatte 61 eingeschraubten Stellschraube 65, die sich am Maschinenteil 60 abstützt, kann der Taumelbolzen 6 mit der Umlenkrolle in der Flucht der Walzen 10, 11 verschwenkt und dadurch der Lauf des Transportbandes 2 korrigiert werden.In order to prevent the conveyor belt 2 from running off the deflection rollers after the axis position of the deflection rollers 3 and 4 has changed, the bearing plate 61, in which the wobble pin 6 is arranged, can be pivoted about an axis 64 running perpendicular to the longitudinal axis of the rollers 10, 11 ( Figure 5). By turning an adjusting screw 65 screwed into the bearing plate 61, which is supported on the machine part 60, the wobble pin 6 with the deflection roller can be pivoted in the alignment of the rollers 10, 11 and the course of the conveyor belt 2 can thereby be corrected.

Die Achse 64 ist in einer Lagerplatte 66 angeordnet, die mittels einer Schraube 67 am Maschinenteil 60 befestigt ist. Nach Lösen dieser Schraube 67 kann die Lagerplatte 66 durch eine Stellschraube 68 in Richtung der Längsachse der Walzen 10, 11 verschoben werden, wodurch das Transportband 2 durch die Umlenkrolle 3 gespannt wird.The axis 64 is arranged in a bearing plate 66 which is fastened to the machine part 60 by means of a screw 67. After loosening this screw 67, the bearing plate 66 can be moved by an adjusting screw 68 in the direction of the longitudinal axis of the rollers 10, 11, whereby the conveyor belt 2 is tensioned by the deflecting roller 3.

In Figur 2 sind dem Quetschwalzenpaar 1 zwei Transportbänder 21 zugeordnet, die jeweils über die erste Umlenkrolle 3 und die zweite Umlenkrolle 4 geführt sind und von der Antriebsrolle 5 angetrieben werden. Der Antrieb der beiden Transportbänder 21 ist gegenläufig. Die Antriebsrollen 5 sind von der Achsverbindungsebene A der Umlenkrollen 3 und 4 entfernt und unmittelbar nebeneinander angeordnet, so daß das Faserband in Transportrichtung P₁ eine zwangsläufige Führung durch die parallel nebeneinander laufenden Transportbänder erhält. Die Antriebsrollen 5 liegen außerdem in der gleichen Antriebsebene und werden über die Antriebswelle 50 gemeinsam angetrieben.In Figure 2, the pair of squeeze rollers 1 are assigned two conveyor belts 21, each of which is guided over the first deflection roller 3 and the second deflection roller 4 and are driven by the drive roller 5. The drive of the two conveyor belts 21 is in opposite directions. The drive rollers 5 are removed from the axis connection plane A of the deflection rollers 3 and 4 and arranged directly next to one another, so that the sliver in the transport direction P 1 receives an inevitable guidance through the parallel parallel conveyor belts. The drive rollers 5 are also in the same drive plane and are driven together via the drive shaft 50.

Das Ausführungsbeispiel nach Figur 3 unterscheidet sich von dem in Figur 2 gezeigten dadurch, daß die Antriebsrollen 5 von der durch den Pfeil P₁ gekennzeichneten Bewegungsbahn des Faserbandes entfernt angeordnet sind, so daß ein Zugang zum Faserbandauslauf vorhanden ist. Das zwischen den Umlenkrollen 4 austretende Faserband wird in einen als Injektor ausgebildeten Bandtrichter 7 gesaugt und von einem Abzugswalzenpaar 8 abgezogen. Die Antriebsrollen 5 liegen auch hier in der gleichen Antriebsebene und werden über die Antriebswelle 50 gemeinsam angetrieben. Von der Antriebswelle 50 wird auch der Antrieb für das Abzugswalzenpaar 8 abgeleitet.The embodiment of Figure 3 differs from that shown in Figure 2 in that the drive rollers 5 are arranged away from the path of movement of the sliver indicated by the arrow P₁, so that access to the sliver outlet is available. The sliver emerging between the deflection rollers 4 is sucked into a belt funnel 7 designed as an injector and drawn off by a pair of take-off rollers 8. The drive rollers 5 are also in the same drive plane and are driven together via the drive shaft 50. The drive for the extraction roller pair 8 is also derived from the drive shaft 50.

Allen Ausführungsbeispielen gemeinsam ist, daß das Transportband 2 bzw. die Transportbänder 21 zusammen mit den Umlenkrollen 3 und 4 und der Antriebsrolle 5 vom Quetschwalzenpaar 1 nach vorn wegschwenkbar ist bzw. sind. Die Schwenkbewegung erfolgt um die Antriebsachse 50 der Antriebsrolle oder Antriebsrollen 5 und wird durch Anschläge 52 begrenzt. Gegebenenfalls kann die Vorrichtung auch verschiebbar angeordnet sein, um den Zugang zu dem Quetschwalzenpaar 1 zu ermöglichen.It is common to all of the exemplary embodiments that the conveyor belt 2 or the conveyor belts 21 together with the deflecting rollers 3 and 4 and the drive roller 5 can be pivoted away from the pair of nip rollers 1 to the front. The pivoting movement takes place about the drive axis 50 of the drive roller or drive rollers 5 and is limited by stops 52. If necessary, the device can also be arranged displaceably in order to allow access to the pair of nip rollers 1.
