Description

Vorrichtung zum Herstellen von Dick/Dünn-Effekten in einem Device for producing thick / thin effects in one
FilamentgarnFilament yarn
Die Erfindung bezieht sich auf eine Vorrichtung zum Herstellen von Dick/Dünn-Effekten in einem Filamentgarn, das in mindestens einem jeweils durch ein Eingangslieferwerk und ein Ausgangslieferwerk begrenzten Reckfeld gereckt wird, wobei zwischen dem Eingangslieferwerk (6) und dem Ausgangslieferwerk (6') eine dem Filamentgarn (1) im Reckfeld wärmezuführende Vorrichtung in Form eines vom Filamentgarn berührten Heizelements (20.1) angeordnet ist und Mittel zum Unterbrechen der Wärmezufuhr vorgesehen sind, nach Patent Nr.... (Patentanmeldung 195 29 315.0-26).The invention relates to a device for producing thick / thin effects in a filament yarn, which is drawn in at least one stretching field, each delimited by an input delivery unit and an output delivery unit, one between the input delivery unit (6) and the output delivery unit (6 ') the filament yarn (1) in the stretching field is arranged in the form of a heating element in contact with the filament yarn (20.1) and means for interrupting the heat supply are provided, according to patent no. (patent application 195 29 315.0-26).
Bei der vorgenannten Vorrichtung ist gemäß einer Ausführungsform vorgeschlagen worden, eine mechanische Einrichtung zum Abheben des Filamentgarns von einer ortsfesten Heizeinrichtung im Reckfeld auf definierten Abschnitten während des Reckens einzusetzen. Das Reckfeld wird durch zwei Galetten/Verlegewalzen-Kombinationen begrenzt, zwischen welchen die vorgenannte mechanische Vorrichtung und die stationäre Heizvorrichtung angeordnet sind. Das Reckfeld kann auch auf mindestens einer Seite durch ein Lieferwalzenpaar (mit Unter/Oberwalze) be- grenzt sein.In the aforementioned device, it has been proposed according to one embodiment to use a mechanical device for lifting the filament yarn from a fixed heating device in the stretching field on defined sections during stretching. The stretching field is delimited by two godet / laying roller combinations, between which the aforementioned mechanical device and the stationary heating device are arranged. The stretching field can also be delimited on at least one side by a pair of delivery rollers (with bottom / top roller).
Bei der vorgenannten Konstruktion kann es sich ergeben, daß durch die mechanische Einrichtung das Filamentgarn in Schwingung versetzt wird, wodurch sich unkontrollierbare Bewegungen für das Filamentgarn ergeben können.With the above-mentioned construction it can result that the filament yarn is set in vibration by the mechanical device, which can result in uncontrollable movements for the filament yarn.
Entsprechend liegt der vorliegenden Erfindung die Aufgabe zugrunde, die vorgenannte Vorrichtung so weiterzubilden, daß das Filamentgarn beim Übertragen von Wärme in den beiden Be- handlungszuständen (erwärmt und nicht erwärmt) so wenig wie möglich unterschiedlich ausgelenkt wird.Accordingly, the object of the present invention is to develop the above-mentioned device in such a way that the filament yarn transfers heat in the two loadings. states of action (warmed and not warmed) are deflected differently as little as possible.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die auf das Filamentgarn wirkende Heizfläche des Heizelements als Umfang mindestens einer über eine Drehachse angetriebenen Scheibe mit in mindestens einem Bereich vermindertem Radius in bezug auf die Drehachse ausgebildet ist. Erfindungsgemäß wird damit vorgeschlagen, nicht das Filamentgarn, sondern das Heiz- element zu bewegen. Die Scheibe und der Fadenlauf sind so zueinander angeordnet, daß das Filamentgarn den Umfang der Scheibe tangiert, dieses Berühren der Einbuchtung also dem verminderten Radius der Scheibe nicht folgt.This object is achieved in that the heating surface of the heating element acting on the filament yarn is formed as the circumference of at least one disk driven via an axis of rotation with a radius which is reduced in at least one region with respect to the axis of rotation. According to the invention, it is thus proposed not to move the filament yarn, but the heating element. The disc and the thread run are arranged so that the filament yarn touches the circumference of the disc, so that touching the indentation does not follow the reduced radius of the disc.
Beim Lauf des Filamentgarns über den Umfang der sich drehenden, beheizten Scheibe wird die Fadenlänge, die die Scheibe berührt und damit erwärmt wird, gereckt, während die Fadenlänge, welche die Einbuchtung der Scheibe nicht berührt, kalt bleibt und demgemäß nicht gereckt wird.As the filament yarn runs over the circumference of the rotating, heated disk, the length of the thread that touches the disk and is thus heated is stretched, while the length of the thread that does not touch the indentation of the disk remains cold and accordingly is not stretched.
Dieser Bereich verbleibt als Dick-Effekt im Filamentgarn.This area remains in the filament yarn as a thick effect.
Dadurch, daß der Faden den Umfang der Scheibe nur tangiert, wird seine Auslenkung zwischen Berühren des Umfangs und Nicht- Berühren des Bereichs verminderten Radius nur minimal unterschiedlich stark ausgelenkt und daher vorteilhafterweise nicht zum Schwingen angeregt. Hierdurch wird die Reproduzierbarkeit der Dickstellenbildung und die Qualität der Dickeffekte verbessert.Because the thread only touches the circumference of the disk, its deflection between touching the circumference and not touching the region of reduced radius is deflected only to a slightly different extent and therefore is advantageously not excited to oscillate. This improves the reproducibility of the thick spot formation and the quality of the thick effects.
Fadenlaufgeschwindigkeit, Drehzahl der Scheibe und Anzahl der Bereiche verminderten Radius der Scheibe bestimmen die Anzahl der Dickstellen entlang des Filamentgarns. Die Länge der Einbuchtung, d.h. der Bereich des verminderten Radius bestimmt in Verbindung mit der Fadenlaufgeschwindigkeit und der Drehzahl sowie der Dicke der Scheibe die Länge der Dickstellen. Unabhängig von der Anzahl der Dickstellen entlang des Filamentgarns kann die Länge der Dickstellen also nur durch Verändern der Länge der Bereiche verminderten Radius entlang des Umfangs der Scheibe verändert werden.Thread speed, speed of the disc and number of areas with reduced radius of the disc determine the number of thick spots along the filament yarn. The length of the indentation, ie the area of the reduced radius, is determined in connection with the thread running speed and the speed and the thickness of the disc the length of the thick spots. Regardless of the number of thick spots along the filament yarn, the length of the thick spots can therefore only be changed by changing the length of the areas of reduced radius along the circumference of the disk.
Die Scheibe ist vorteilhafterweise gegen solche mit anderer Länge des Bereichs verminderten Radius entlang des Umfangs der Scheibe austauschbar.The disk is advantageously interchangeable with a radius of a reduced length along the circumference of the disk.
In weiterer Ausgestaltung der Erfindung können zwei Scheiben im gegenseitigen Abstand angeordnet und beispielsweise drehzahlunabhängig voneinander antreibbar sein.In a further embodiment of the invention, two disks can be arranged at a mutual distance and can be driven, for example, independently of one another by speed.
Es besteht alternativ auch die Möglichkeit, daß eine Scheibe aus zwei oder mehr mit ihren jeweiligen Bereichen mit vermindertem Radius gegeneinander verdrehbaren Teilscheiben besteht.Alternatively, there is also the possibility that a disk consists of two or more partial disks which can be rotated relative to one another with their respective regions with a reduced radius.
Bei einer Ausführungsform der Erfindung kann die Drehachse der Scheibe zur Laufrichtung des Filamentgarns zumindest annähernd parallel sein. Alternativ ist auch eine Konstruktion einsetzbar, bei welcher die Drehachse der Scheibe in einer Ebene liegt, die mit der Laufrichtung des Filamentgarns zumindest annähernd einen rechten Winkel bildet.In one embodiment of the invention, the axis of rotation of the disk can be at least approximately parallel to the running direction of the filament yarn. Alternatively, a construction can also be used in which the axis of rotation of the disk lies in a plane which at least approximately forms a right angle with the running direction of the filament yarn.
Allen Ausführungsformen ist gemeinsam, daß die Scheiben durch mindestens eine in unmittelbarer Nähe angeordnete, ortsfeste Heizeinrichtung über Konvektion, Strahlung oder Induktion beheizbar sind.All embodiments have in common that the panes can be heated by at least one stationary heating device arranged in the immediate vicinity via convection, radiation or induction.
Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsbeispielen näher beschrieben. In der Zeichnung zeigen: Fig. 1 eine schematische Seitenansicht einer ersten Ausführungsform der Erfindung,The invention is described below with reference to exemplary embodiments shown in the drawing. In the drawing show: 1 is a schematic side view of a first embodiment of the invention,

In Fig. 1 ist eine Vorrichtung zum Herstellen von Dick/Dünn- Effekten in einem Filamentgarn 1 dargestellt. Es finden zwei Galetten/Verlegewalzen-Kombinationen in Form eines Eingangs- lieferwerkes 6 und eines Ausgangslieferwerkes 6' Anwendung, zwischen welchen das Filamentgarn 1 in einem Reckfeld I gereckt wird. Das Reckfeld kann auch auf mindestens einer Seite durch ein Lieferwalzenpaar (mit Unter/Oberwalze) begrenzt sein.1 shows a device for producing thick / thin effects in a filament yarn 1. Two godet / laying roller combinations in the form of an input delivery unit 6 and an output delivery unit 6 'are used, between which the filament yarn 1 is stretched in a stretching field I. The stretching field can also be delimited on at least one side by a pair of delivery rollers (with bottom / top roller).
In diesem Reckfeld I befindet sich ein Heizelement 20.1, welches aus einer Scheibe 60 und einer in unmittelbarer Nähe derselben angeordneten, ortsfesten Heizeinrichtung 62 besteht. Durch diese Heizeinrichtung 62 kann die Scheibe über Konvek- tion und/oder durch Strahlung beheizt werden.In this stretching field I there is a heating element 20.1, which consists of a disk 60 and a stationary heating device 62 arranged in the immediate vicinity thereof. By means of this heating device 62, the pane can be heated by convection and / or by radiation.
Die Scheibe 60 wird über eine Drehachse 65 von einem Motor 61 angetrieben.The disk 60 is driven by a motor 61 via an axis of rotation 65.
Aus Fig. 2 geht hervor, daß der Umfang U der beheizten Scheibe 60 als Heizfläche für das Filamentgarn dient, wobei die Scheibe 60 außerdem mit einem Bereich verminderten Radius R in bezug auf die Drehachse 65 ausgebildet ist. Dieser Bereich R mit verminderten Radius bildet also eine Einbuchtung, welche das Filamentgarn nicht berührt, so daß dieses kalt bleibt und demgemäß nicht gereckt wird. Es ergibt sich damit eine Dickstelle im Filamentgarn. Ein Recken erfolgt beim Lauf des Filamentgarns über den Umfang U der sich drehenden, beheizten Scheibe 60.2 that the circumference U of the heated disk 60 serves as a heating surface for the filament yarn, the disk 60 also being designed with a region of reduced radius R with respect to the axis of rotation 65. This area R with a reduced radius thus forms an indentation which does not touch the filament yarn, so that it remains cold and accordingly is not stretched. This results in a thick spot in the filament yarn. The filament yarn is stretched over the circumference U of the rotating, heated disk 60.
Die Scheibe 60 kann auch mehrere Einbuchtungen R und Einbuchtungen unterschiedlicher Länge in Umfangsrichtung aufweisen, die zudem zufälllig um den Umfang verteilt sein können. Dadurch kann beliebige Anzahl, Länge und Verteilung von Dick- stellen entlang des Filaments erreicht werden.The disk 60 can also have a plurality of indentations R and indentations of different lengths in the circumferential direction, which can also be randomly distributed around the circumference. This means that any number, length and distribution of thick spots along the filament can be achieved.
Bei der Ausführungsform nach Fig. 1 und 2 findet lediglich eine Scheibe 60 Anwendung. Entsprechend der Ausführungsform nach Fig. 3 können zwei Scheiben 60 und 60' im gegenseitigen Abstand angeordnet sein. Hierbei besteht die Möglichkeit, daß die beiden Scheiben 60 und 60' drehzahlunabhängig voneinander antreibbar sind, und zwar mit Hilfe der Motoren 61 und 61'.In the embodiment according to FIGS. 1 and 2, only one disk 60 is used. According to the embodiment according to FIG. 3, two disks 60 and 60 'can be arranged at a mutual distance. There is the possibility that the two disks 60 and 60 'can be driven independently of one another by means of the motors 61 and 61'.
Die beiden Scheiben 60, 60' können auch auf einer gemeinsamen Achse sitzen, wobei ihre Einbuchtungen R in verschiedene Richtungen weisen. Bevorzugt ist die dargestellte Ausführung mit gesonderten Antrieben der Scheiben, weil damit eine größere Zufälligkeit der Verteilung der Dickstellen erreichbar ist.The two disks 60, 60 'can also sit on a common axis, their indentations R pointing in different directions. The embodiment shown with separate drives of the disks is preferred because a greater randomness of the distribution of the thick spots can be achieved thereby.
Hierbei kann eine erwünschte zufällige Verteilung der Dickstellen entlang des Filaments durch unterschiedliche und auch wechselnde Drehzahlen der beiden Scheiben 60 und 60' erreicht werden. Eine Heizeinrichtung 62 befindet sich hier zwischen den beiden Scheiben 60 und 60' und beheizt beide. Es kann natürlich auch jede der Scheiben eine eigene Heizeinrichtung haben. Jede der Scheiben 60 und 60' kann analog der Ausführungsform nach Fig. 2 gestaltet sein, und zwar z.B. mit gegeneinander verdrehten Bereichen R, in welchen das Filamentgarn 1 nicht berührt wird. Eine weitere Ausführungsform der Erfindung ist in Fig. 4 dargestellt: Hier findet eine Scheibe 60'' Anwendung, welche aus zwei mit ihren jeweiligen Bereichen mit vermindertem Radius Rγ und R2 gegeneinander verdrehbaren Teilscheiben 60.1 und 60.2 besteht. Beide Teilscheiben 60.1 und 60.2 weisen eine gemeinsame Drehachse 65 auf. Ferner ist jeweils ein Langloch 67 vorgesehen, welches von einer Klemmschraube 68 durchsetzt wird. Damit ist es möglich, die beiden Teilscheiben 60.1 und 60.2 gegeneinander zu verdrehen und damit die Bereiche mit vermindertem Radius R, und R2 entsprechend zu verstellen.In this case, a desired random distribution of the thick spots along the filament can be achieved by different and alternating speeds of the two disks 60 and 60 '. A heating device 62 is located between the two disks 60 and 60 'and heats both. Of course, each of the panes can also have its own heating device. Each of the disks 60 and 60 'can be designed analogously to the embodiment according to FIG. 2, for example with regions R twisted relative to one another, in which the filament yarn 1 is not touched. A further embodiment of the invention is shown in FIG. 4: Here, a disk 60 ″ is used, which consists of two partial disks 60.1 and 60.2 which can be rotated relative to one another with their respective areas with a reduced radius R γ and R 2 . Both dividing disks 60.1 and 60.2 have a common axis of rotation 65. Furthermore, an elongated hole 67 is provided, which is penetrated by a clamping screw 68. It is thus possible to rotate the two indexing disks 60.1 and 60.2 against one another and thus to adjust the areas with a reduced radius R, and R 2 accordingly.
Hierdurch kann ebenso wie durch - unterschiedliche - Drehzahl der Scheiben 60, 60' die Länge der erzeugten Dickstellen eingestellt werden.As a result, the length of the thick spots generated can be set just as by - different - speed of the disks 60, 60 '.
Bei den Ausführungsformen nach Fig. 1 bis 4 liegt jeweils die Drehachse 65 der Scheiben 60 bzw. 60' bzw. 60'' zumindest annähernd parallel zur Laufrichtung des Filamentgarns. In nicht näher dargestellter Ausführungsform besteht auch die Möglichkeit, daß die Drehachse der vorgenannten Scheibe in einer Ebene liegt, welche mit der Laufrichtung des Filamentgarns 1 zumindest einen annähernd rechten Winkel bildet.In the embodiments according to FIGS. 1 to 4, the axis of rotation 65 of the disks 60 or 60 'or 60' 'is at least approximately parallel to the running direction of the filament yarn. In an embodiment, not shown, there is also the possibility that the axis of rotation of the aforementioned disk lies in a plane which forms at least an approximately right angle with the running direction of the filament yarn 1.
Allen Ausführungsformen ist gemeinsam, daß Fadenlaufgeschwin- digkeit, Drehzahl der Scheibe und Anzahl der Einbuchtungen R bzw. R| bzw. R2 der Scheibe die Anzahl der Dickstellen entlang des Filamentgarns bestimmen. Die Länge der Einbuchtung entlang des Umfangs der Scheibe bestimmt darüber hinaus in Verbindung mit der Fadenlaufgeschwindigkeit und der Drehzahl sowie der Dicke der Scheibe die Länge der Dickstellen. Dadurch, daß dasAll embodiments have in common that the thread running speed, the speed of the disk and the number of indentations R and R | or R 2 of the disk determine the number of thick spots along the filament yarn. The length of the indentation along the circumference of the disk also determines the length of the thick spots in connection with the thread running speed and the speed as well as the thickness of the disk. Because that
Filamentgarn 1 den Umfang der jeweiligen Scheibe nur tangiert, wird vorteilhafterweise seine Auslenkung durch Berühren desFilament yarn 1 only affects the circumference of the respective disk, its deflection is advantageously by touching the
Umfangs U bzw. Nicht-Berühren der jeweiligen Einbuchtung nur minimal unterschiedlich stark ausgelenkt und nicht zum Schwin- gen angeregt. Die Drehzahl der Scheibe bzw. der Scheiben kann, z.B. zufällig, veränderbar sein, um eine zufällige Verteilung der Dickstellen entlang des Filamentgarns 1 zu erreichen. Darüber besteht die Möglichkeit, daß die Scheibe oder die Scheiben mehr als einen Bereich mit vermindertem Radius aufweisen; außerdem können mehrere derartige Bereiche in Umfangsrichtung unterschiedlich lang und/oder zufällig entlang des Umlaufs verteilt sein.The circumference U or not touching the respective indentation is deflected only to a slightly different extent and is not stimulated to vibrate. The rotational speed of the disk or disks can be changeable, for example at random, in order to achieve a random distribution of the thick spots along the filament yarn 1. In addition, there is the possibility that the disk or disks have more than one area with a reduced radius; moreover, several such regions can be distributed in the circumferential direction of different lengths and / or randomly along the circumference.
Es besteht bezüglich der Gestaltung des Heizelements auch die Möglichkeit, die Scheibe selbst direkt zu beheizen und dafür auf die Heizeinrichtung 62 zu verzichten. With regard to the design of the heating element, there is also the possibility of directly heating the pane itself and for doing so without the heating device 62.
