Die Erfindung betrifft eine Streckvorrichtung für textile Faserbänder, aufweisend ein Streckwerk, das auf einem Ablagegehäuse aufgenommen ist, und aufweisend wenigstens eine seitliche Haube, die benachbart zum Streckwerk auf dem Ablagegehäuse angeordnet ist, und wobei die seitliche Haube mittels einer Gelenkanordnung über dem Ablagegehäuse aufklappbar aufgenommen ist.The invention relates to a stretching device for textile slivers, comprising a drafting device, which is accommodated on a storage housing, and comprising at least one lateral hood, which is arranged adjacent to the drafting device on the storage housing, and wherein the lateral hood by means of a hinge assembly on the storage housing hinged is.
Streckvorrichtungen können dazu verwendet werden, einzelne Faserbänder aus mehreren Kannen über eine sogenannte Gatteranordnung mit den Kannen zugeordneten Gattern einzuziehen, nebeneinander anzulegen, zu strecken, und anschließend zu einem neuen, einzigen Faserband zusammenzuführen, das vorzugsweise die gleichen Querschnittsabmessungen aufweist wie jedes einzelne der eingezogenen, mehreren Faserbänder. Zum Einziehen der Faserbänder werden Rechengatter oder angetriebene Gatterrollen verwendet, und es kann eine Vielzahl von einzelnen Kannen vorgelagert sein, aus denen die Faserbänder entnommen werden, um die Ausbringung der Streckanlage zu vergrößern.Stretching devices can be used to feed single fiber slivers from several cans via a so-called gate arrangement with the cans associated with the cans, adjacent to each other, stretch, and then merge into a new, single sliver, which preferably has the same cross-sectional dimensions as each of the retracted, several slivers. Calculating gates or driven creel rolls are used to retract the fiber ribbons, and a plurality of individual tundishes from which the fiber ribbons are removed to increase the yield of the stretching plant can be preceded.
Zur weiteren Effizienzsteigerung von Streckvorrichtungen ist es bekannt, beispielsweise zwei Streckvorrichtungen zu einer gemeinsamen Streckanlage zusammenzuführen, welche Komponenten der einzelnen Streckvorrichtungen gemeinsam nutzen. So ist es beispielsweise möglich, die Gatter der zwei Streckvorrichtungen auf eine gemeinsame Gatteranordnung zu reduzieren, ferner können periphere Einrichtungen wie beispielsweise eine Faserabsaugung oder dergleichen gemeinsam genutzt werden.To further increase the efficiency of stretching devices, it is known, for example, to combine two stretching devices into a common stretching device, which share components of the individual stretching devices. For example, it is possible to reduce the gates of the two stretchers to a common gate arrangement, and peripheral equipment such as fiber exhaust or the like may be shared.
Eine weitere Effizienzsteigerung wird dadurch erreicht, dass den Streckvorrichtungen eine größere Anzahl von Kannen vorgelagert wird. Sind beispielsweise 16 Kannen vorgelagert, aus denen über die Gatteranordnung die einzelnen Faserbänder dem Streckwerk der Streckvorrichtung zugeführt werden, so muss die befüllte Kanne in der Streckvorrichtung sehr häufig gewechselt werden, bis schließlich die Faserbänder aus den bereitgestellten Kannen auslaufen und neue Kannen bereitgestellt werden müssen. Folgerichtig ergibt sich eine weitere Effizienzsteigerung einer Streckvorrichtung dadurch, dass die befüllbaren Kannen vergrößert werden.A further increase in efficiency is achieved in that the stretching devices are preceded by a larger number of cans. For example, 16 cans upstream, from which the individual fiber slivers via the gate arrangement be fed to the drafting of the drafting device, the filled can in the stretching device must be changed very often, until finally the slivers from the provided cans expire and new cans must be provided. Consequently, a further increase in efficiency of a stretching device results from the fact that the refillable cans are enlarged.
Aufgrund konstruktiver Begrenzungen und der Weiterverwendung vorhandener Streckvorrichtungen zur Aufnahme kleinerer Kannen sind konstruktive Maßnahmen erforderlich, um die Streckvorrichtung so auszulegen, dass größere Kannen in der Streckvorrichtung befüllt werden können. Dabei sind mehrere Faktoren zur wirtschaftlichen Bereitstellung einer vergrößerten Streckvorrichtung zu berücksichtigen, insbesondere die verfügbaren Ausgangsmaterialien, aus denen eine Streckvorrichtung hergestellt wird. Weiterhin sind Aspekte wie die Transportfähigkeit der bis über 1,5 t wiegenden einzelnen Streckvorrichtung zu berücksichtigen, sodass eine einfache Größenskalierung einer bekannten Streckvorrichtung zur Befüllung kleinerer Kannen mit einem Durchmesser von beispielsweise 1000 mm grundsätzlich nicht möglich ist, um die Kannengröße einer Streckvorrichtung zu vergrößern. Das Ablagegehäuse bildet abweichend vom Bedeutungsinhalt eines Gehäuses zur Umschließung eines Volumens im Wesentlichen eine Platte, auf der das Streckwerk aufgenommen ist. Die Aufnahme des Streckwerkes erfolgt auf einer Oberseite des Ablagegehäuses, und auf der Unterseite des Ablagegehäuses befindet sich die Ablagekanne, die unter dem Ablagegehäuse eine Drehbewegung ausführt. Das Ablagegehäuse kann Verkleidungselemente umfassen, die auf der Oberseite der Plattensegmente angeordnet sind und sich insbesondere neben der Anordnung des Streckwerkes befinden. Da das Ablagegehäuse auch zur Aufnahme von elektrischen Leitungen, von Druckluftleitungen und dergleichen dient, bildet dieses folglich durchaus ein Gehäuse für die weiteren Komponenten der Streckvorrichtung. Eine seitliche Haube befindet sich bei bekannten Streckvorrichtungen, wie zum Beispiel in der Offenbarung
Aufgabe der Erfindung ist die Weiterbildung einer Streckvorrichtung für textile Faserbänder, die zur Aufnahme einer vergrößerten Kanne zur Befüllung mit einem Faserband ausgebildet ist. Insbesondere soll dabei die Streckvorrichtung so weitergebildet werden, dass möglichst viele Komponenten von kleineren Streckvorrichtungen weiterverwendet werden können. Überdies sollen Ausgangsmaterialien berücksichtigt werden, die grundsätzlich einfach verfügbar sind.The object of the invention is the development of a stretching device for textile slivers, which is designed to receive an enlarged can for filling with a sliver. In particular, the stretching device should be developed so that as many components as possible can be reused by smaller stretching devices. Moreover, starting materials should be taken into account, which are basically readily available.
Diese Aufgabe wird ausgehend von einer Streckvorrichtung für textile Faserbänder gemäß dem Oberbegriff des Anspruches 1 und ausgehend von einer Streckanlage gemäß Anspruch 12 mit den jeweils kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.This object is achieved starting from a stretching device for textile slivers according to the preamble of claim 1 and starting from a stretching system according to
Die Erfindung schließt die Lehre ein, dass ein Längenadapterteil auf dem Ablagegehäuse aufgenommen ist, wobei die seitliche Haube am Längenadapterteil mittels der Gelenkanordnung verschwenkbar und damit beweglich aufgenommen ist, und wobei die Gelenkanordnung an einer Vorderseite des Längenadapterteils angeordnet ist und wobei eine der Vorderseite gegenüberliegende Hinterseite des Längenadapterteils mit einer Hinterkante des Ablagegehäuses abschließt.The invention includes the teaching that a length adapter part is accommodated on the storage housing, wherein the lateral hood on the length adapter part by means of the hinge assembly is pivotally and thus movably received, and wherein the hinge assembly is disposed on a front side of the length adapter part and wherein a rear side opposite the front the length adapter part terminates with a trailing edge of the storage housing.
Die erfindungsgemäße Anordnung eines Längenadapterteils auf dem Ablagegehäuse ermöglicht auf vorteilhafte Weise die Verwendung einer einheitlichen Haube zur einseitigen oder beidseitigen Anordnung neben dem Streckwerk für unterschiedlich große Streckvorrichtungen, wobei die Verwendung der gleichen seitlichen Haube auch bei einer Verlängerung des Ablagegehäuses vorgesehen werden kann, sodass trotz der Verlängerung die Hinterseite des Längenadapterteils mit der Hinterkante des Ablagegehäuses abschließt. Konventionell ist die seitliche Haube an der Hinterkante des Ablagegehäuses beziehungsweise an einer zugeordneten Box aufgenommen, die sich an die Hinterkante des Ablagegehäuses rückseitig abschließt. Die Haube schließt im Schließzustand an ein Bauteil im vorderen Bereich des Ablagegehäuses an und wird das Ablagegehäuse zur Aufnahme größerer Ablagekannen verlängert, so besteht vorteilhaft die Möglichkeit, mit dem Längenadapterteil konventionell ausgestaltete Hauben auch für Streckvorrichtungen vorzusehen, die Ablagekannen mit unterschiedlichen Größen aufnehmen.The arrangement according to the invention of a length adapter part on the storage housing advantageously allows the use of a unitary hood for one-sided or two-sided arrangement in addition to the drafting device for different sized stretching devices, wherein the use of the same lateral hood can be provided even with an extension of the storage housing, so that despite the Extension terminates the rear of the length adapter part with the trailing edge of the storage housing. Conventional is the lateral Hood on the trailing edge of the storage housing or received on an associated box, which terminates at the rear edge of the storage housing on the back. The hood closes in the closed state to a component in the front region of the storage housing and the storage housing is extended to accommodate larger storage cans, it is advantageously possible to provide with the length adapter part conventionally configured hoods for stretchers that accommodate storage churns of different sizes.
Erfindungsgemäß kann das Längenadapterteil so bemaßt sein, dass eine Verlängerung des Ablagegehäuses in Längsrichtung der Streckvorrichtung möglich wird, ohne konstruktive Änderungen an der seitlichen Haube vorzunehmen. Die Längsrichtung des Ablagegehäuses und damit der Streckvorrichtung entspricht dabei der Richtung, aus der die textilen Faserbänder dem Streckwerk auf dem Ablagegehäuse zugeführt werden. Werden beispielsweise Ablagekannen mit einem Durchmesser von 1200 mm in der Streckvorrichtung zur Befüllung aufgenommen und werden zwei Ablagekannen in Längsrichtung voreinander angeordnet, so vergrößert sich die Länge des Ablagegehäuses in Längsrichtung um ein entsprechendes Längenmaß gegenüber einer Steckvorrichtung, die zur Aufnahme und zur Befüllung von kleineren Ablagekannen ausgebildet ist. Unter Beibehaltung der geometrischen Ausgestaltung der seitlichen Haube und weiteren Auf- und Anbauteilen auf oder an dem Ablagegehäuse kann mittels der Verwendung des Längenadapterteils die Streckvorrichtung mit einer großen Anzahl von gleichen Komponenten aufgebaut werden, sodass die Streckvorrichtung modulartig ausgebildet ist und zur entsprechenden Aufnahme verschieden großer Ablagekannen dient.According to the invention, the length adapter part can be dimensioned so that an extension of the storage housing in the longitudinal direction of the stretching device is possible without making any structural changes to the side hood. The longitudinal direction of the storage housing and thus the stretching device corresponds to the direction from which the textile fiber ribbons are fed to the drafting system on the storage housing. For example, if storage churns with a diameter of 1200 mm are included in the stretching device for filling and two storage cans in the longitudinal direction are arranged in front of each other, so the length of the storage housing in the longitudinal direction by a corresponding length dimension increases compared to a plug-in device for receiving and filling smaller storage jugs is trained. While maintaining the geometric design of the side hood and other components and attachments on or on the storage housing by means of the use of the length adapter part, the stretching device can be constructed with a large number of the same components, so that the stretching device is formed like a module and correspondingly receiving different sized storage cans serves.
Es ist bekannt, dass zur Unterstützung der Öffnungsbewegung der seitlichen Haube ein Haubenliftelement verwendet wird, das sich bei einer geschlossenen seitlichen Haube unterhalb der Haube befindet. Erfindungsgemäß ist ein solches Haubenliftelement am Längenadapterteil angeordnet, und wobei das Haubenliftelement am Längenadapterteil mit einer Endseite insbesondere gelenkig angeordnet ist.It is known that a hood lift element is used to assist the opening movement of the side hood, which is located below the hood with a closed side hood. According to the invention, such a hood lift element is arranged on the length adapter part, and wherein the hood lift element is arranged in particular articulated on length adapter part with one end side.
An einer Hinterseite des Ablagegehäuses ist gemäß einer weiteren Ausgestaltung der Streckvorrichtung eine Box zur Aufnahme von Betriebseinrichtungen zum Betrieb der Streckvorrichtung angeordnet, wobei die Hinterseite des Längenadapterteils an die Box angrenzt. Ein besonderer Vorteil wird erreicht, wenn das Längenadapterteil an der Box mittels einer Schraubanordnung verschraubt ist. Beispielsweise weist das Längenadapterteil hierfür einen Rechteckrahmen und Stangenelemente auf, über die der Rechteckrahmen beabstandet zur Oberfläche des Ablagegehäuses an diesem aufgenommen ist. Der Rechteckrahmen selbst kann mit einer Schraubanordnung an der Box verschraubt sein, sodass der Rechteckrahmen und die Box mittels der Schraubanordnung miteinander verbunden sind. Damit wird vorteilhaft erreicht, dass der Rechteckrahmen auf der Hinterseite mit der Box verschraubt ist und mit den Stangenelementen auf der Vorderseite über dem Ablagegehäuse aufgenommen ist. Somit bildet das Längenadapterteil einen Hohlraum, in den insbesondere Komponenten einer Faserabsaugung oder dergleichen aufgenommen sind.At a rear side of the storage housing, a box for receiving operating devices for operating the stretching device is arranged according to a further embodiment of the stretching device, wherein the rear side of the length adapter part adjacent to the box. A particular advantage is achieved if the length adapter part is screwed to the box by means of a screw arrangement. For example, the length adapter part for this purpose has a rectangular frame and rod elements, via which the rectangular frame is received at a distance from the surface of the storage housing at this. The rectangular frame itself can be screwed to the box with a screw arrangement, so that the rectangular frame and the box are connected to one another by means of the screw arrangement. This is advantageously achieved that the rectangular frame is bolted to the rear of the box and is added to the rod elements on the front over the storage housing. Thus, the length adapter part forms a cavity, in particular components of a fiber extraction or the like are accommodated.
Mit besonderem Vorteil weist das Längenadapterteil eine Länge von der Vorderseite bis zur Hinterseite auf, wobei an der Vorderseite die seitliche Haube mit der Gelenkanordnung aufgenommen ist und wobei die Hinterseite an die Box angrenzt. Folglich korrespondiert die Länge des Längenadapterteils von der Vorderseite bis zur Hinterseite mit der Verlängerung des Ablagegehäuses, wobei die Verlängerung des Ablagegehäuses so bestimmt ist, dass unter dem Ablagegehäuse zwei Ablagekannen mit einem Durchmesser von 1200 mm voreinander anordbar sind.Particularly advantageously, the length adapter part has a length from the front side to the rear side, the lateral hood having the hinge arrangement being accommodated on the front side and the rear side being adjacent to the box. Consequently, the length of the length adapter part from the front to the back corresponds to the extension of the storage housing, wherein the extension of the storage housing is determined so that under the storage housing two storage cans with a diameter of 1200 mm are arranged in front of each other.
Das Längenadapterteil weist mit weiterem Vorteil ein Gehäuse auf, das haubenartig über dem Rechteckrahmen angeordnet ist. Das Gehäuse kann beispielsweise U-förmig ausgeführt sein und deckt den Rechteckrahmen derart weit ab, dass das Gehäuse mit Randabschnitten bis auf die Oberfläche des Ablagegehäuses ragen kann. Das Gehäuse kann insbesondere mit dem Rechteckrahmen verschraubt werden, um das Längenadapterteil zu verschließen.The length adapter part has, with further advantage, a housing which is arranged like a hood over the rectangular frame. The housing may for example be designed U-shaped and covers the rectangular frame so far from that Casing with edge sections can protrude to the surface of the storage housing. The housing can in particular be screwed to the rectangular frame in order to close the length adapter part.
Auch ist es vorteilhaft möglich, dass auf dem Ablagegehäuse eine Faserbandzufuhr angeordnet ist, die eine Zusatzlänge aufweist, die der Länge des Längenadapterteils von der Vorderseite bis zur Hinterseite des Längenadapterteils entspricht.It is also advantageously possible for a sliver feed to be arranged on the storage housing which has an additional length which corresponds to the length of the length adapter part from the front side to the rear side of the length adapter part.
Die Erfindung richtet sich weiterhin auf eine Streckanlage mit einer ersten Streckvorrichtung und mit einer zweiten Streckvorrichtung, wobei die Merkmale und zugehörigen Vorteile der jeweiligen Streckvorrichtung vorstehend bereits beschrieben sind.The invention is further directed to a stretching machine with a first stretching device and with a second stretching device, wherein the features and associated advantages of the respective stretching device are already described above.

In den über der Höhe der Säulen gebildeten Zwischenraum zwischen der Grundplatte 29 und dem Ablagegehäuse 11 befinden sich zwei Ablagekannen 24, wobei eine vorderseitige Ablagekanne 24 eine aktuell befüllbare Ablagekanne 24 bildet, und eine dahinter angeordnete Ablagekanne 24 bildet eine weitere Ablagekanne 24, die über ein Kannenwechselsystem an die vorderseitige Position der ersten Ablagekanne 24 befördert wird, wenn die vorderseitige Ablagekanne 24 voll ist.The stretchers 1 have a basic structure of a
Seitlich neben dem Streckwerk 10 befindet sich jeweils eine Haube 12 auf der Oberseite des Ablagegehäuses 11. Die Haube 12 ist erfindungsgemäß verschwenkbar bzw. beweglich an einem Längenadapterteil 14 angeordnet, und diese kann bei Bedarf nach oben verschwenkt werden. Dabei ist die Haube 12 über Gelenke an dem Längenadapterteil 14 verschwenkbar aufgenommen.In each case, a
Auf beiden Seiten benachbart zum Streckwerk 10 befinden sich auf dem Ablagegehäuse 11 Hauben 12, die über Gelenkanordnungen 13 beweglich an dem jeweiligen Längenadapterteil 14 aufgenommen sind, wobei auch jeweils ein Längenadapterteil 14 auf beiden Seiten zum Streckwerk 10 bzw. zu einer Faserbandzufuhr 25 auf dem Ablagegehäuse 11 aufgenommen ist. Das jeweilige Längenadapterteil 14 besitzt ein Gehäuse 28, das in der Außenkontur angepasst ist an die Außenkontur der jeweiligen Haube 12 im Bereich der Gelenkanordnung 13. Zwischen den beiden Längenadapterteilen 14 respektive zwischen den beiden Hauben 12 befindet sich die Faserbandzufuhr 25, über die die textilen Faserbänder zum Einlauf in das Streckwerk 10 parallel nebeneinander geführt werden können.On both sides adjacent to the
Die Streckvorrichtung 1 ist zur Aufnahme von Ablagekannen 24 ausgelegt, die einen Durchmesser von 1200 mm aufweisen. Dadurch verbreitert sich die Streckvorrichtung 1 quer zur Zufuhrrichtung der Faserbänder, zusätzlich verlängert sich die Streckvorrichtung 1, damit beide Ablagekannen 24 mit einem jeweiligen Durchmesser von 1200 mm hintereinander im Zwischenraum zwischen dem Ablagegehäuse 11 und der Grundplatte 29 aufgenommen werden können. Aufgrund der vergrößerten Länge der Streckvorrichtung 1 ist das Ablagegehäuse 11 ebenfalls verlängert ausgebildet, und um eine Haube 12 zu verwenden, die auch für kleinere Streckvorrichtungen 1 Verwendung finden kann, dient erfindungsgemäß das Längenadapterteil 14. Dieses gleicht die zusätzlich hinzugenommene Länge des Ablagegehäuses 11 aus, sodass die Haube 12 baugleich zu Hauben für Streckvorrichtungen 1 ausgeführt werden kann, die zur Aufnahme kleinerer Ablagekannen 24 ausgebildet sind. Die bewegliche Aufnahme der Haube 12 ist durch eine teilweise gestrichelt dargestellte, leicht geöffnete Haube 12 gezeigt. Die Faserbandzufuhr 25 ist um einen Betrag verlängert ausgeführt, der mit der vergrößerten Länge des Ablagegehäuses 11 korrespondiert.The stretching device 1 is designed to receive
Das Längenadapterteil 14 weist einen Rechteckrahmen 21 auf, der an der Vorderseite 15 mittels Stangenelementen 22 auf dem Ablagegehäuse 11 beabstandet aufgenommen ist. Durch die beabstandete Aufnahme des Rechteckrahmens 21 entsteht ein Hohlraum 23, in dem nicht näher dargestellte Betriebs- und Versorgungseinrichtungen zum Betrieb der Streckvorrichtung 1 aufgenommen oder hindurchgeführt werden.The
Das Ablagegehäuse 11 besitzt eine Hinterkante 17, mit der die Hinterseite 16 des Längenadapterteils 14 abschließt, sodass die Box 19 an der Hinterkante 17 des Ablagegehäuses 11 und zugleich an der Hinterseite 16 des Längenadapterteils 14 angeordnet werden kann. Aufgrund der konstruktiven Ausgestaltung sind keine wesentlichen Änderungen zum Beispiel an der Box 19 oder an der Haube 12 notwendig, und durch die bloße Verlängerung des Ablagegehäuses 11 können eine Vielzahl von Elementen der Streckvorrichtung 1 für verschiedene Größen der Streckvorrichtung 1 zur Aufnahme unterschiedlicher Ablagekannen verwendet werden. Lediglich die Verschraubung des Längenadapterteils 14 an der Box 19 erfordert eine geringfügige Nachbearbeitung der ansonsten zu anderen Streckvorrichtungen 1 baugleichen Box 19.The
