Description

Die Erfindung betrifft eine Streckvorrichtung für textile Faserbänder, aufweisend ein Streckwerk, das auf einem Ablagegehäuse aufgenommen ist, und aufweisend eine Grundplatte, auf der wenigstens eine Ablagekanne drehbar aufnehmbar ist, und wobei das Ablagegehäuse mittels Säulen beabstandet über der Grundplatte angeordnet ist, und wobei die Streckvorrichtung so ausgebildet ist, dass wenigstens eine Ablagekanne mit einem Durchmesser von 1200 mm auf der Grundplatte aufnehmbar und mit dem textilen Faserband befüllbar ist.The invention relates to a drafting device for textile fiber slivers, having a drafting system which is accommodated on a storage housing, and having a base plate on which at least one storage can can be rotatably accommodated, and the storage housing being arranged at a distance above the base plate by means of columns, and the Stretching device is designed so that at least one storage can with a diameter of 1200 mm can be accommodated on the base plate and filled with the textile sliver.

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 draw in individual slivers from several cans via a so-called creel arrangement with creels assigned to the cans, lay them next to one another, stretch them and then bring them together to form a new, single sliver, which preferably has the same cross-sectional dimensions as each of the drawn-in, several slivers. Rake creels or driven creel rollers are used to pull in the slivers, and a large number of individual cans can be upstream from which the slivers are removed in order to increase the output of the drafting system.

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.In order to further increase the efficiency of stretching devices, it is known, for example, to combine two stretching devices to form a common stretching system, which uses components of the individual stretching devices together. For example, it is possible to reduce the gates of the two stretching devices to a common gate arrangement, and peripheral devices such as a fiber suction device or the like can also be used jointly.

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 by placing a larger number of cans in front of the drawing devices. If, for example, 16 cans are upstream, from which the individual slivers are fed to the drafting system of the drafting device via the creel arrangement, the filled can must be changed very frequently in the drafting device until the slivers finally run out of the provided cans and new cans have to be provided. Consequently, a further increase in the efficiency of a stretching device results from the fact that the cans that can be filled are increased.

Aufgrund konstruktiver Begrenzungen und der Weiterverwendung vorhandener Komponenten von 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.Due to structural limitations and the further use of existing components of stretching devices for accommodating smaller cans, structural measures are necessary in order to design the stretching device in such a way that larger cans can be filled in the stretching device. There are several factors to consider in economically providing an enlarged stretcher, most notably the available starting materials from which to fabricate a stretcher. Furthermore, aspects such as the transportability of the individual stretching device weighing up to more than 1.5 t must be taken into account, so that a simple scaling of the size of a known stretching device for filling smaller cans with a diameter of 1000 mm, for example, is fundamentally not possible in order to increase the can size of a stretching device.

Die EP 3 165 635 A1 offenbart eine Streckvorrichtung mit zwei Streckwerken und zwei Kannenablagevorrichtungen, unter denen Kannen zum Befüllen transportiert werden können.the EP 3 165 635 A1 discloses a drafting device with two drafting systems and two can depositing devices, under which cans can be transported for filling.

Aufgabe der Erfindung ist die Weiterbildung einer Streckvorrichtung für textile Faserbänder, die zur Aufnahme einer vergrößerten Ablagekanne zur Befüllung mit einem Faserband ausgebildet ist. Insbesondere soll dabei die Streckvorrichtung transportabel bleiben.The object of the invention is the further development of a stretching device for textile slivers, which is designed to accommodate an enlarged storage can for filling with a sliver. In particular, the stretching device should remain transportable.

Diese Aufgabe wird ausgehend von einer Streckvorrichtung für textile Faserbänder gemäß dem Oberbegriff des Anspruches 1 und ausgehend von einer Streckanlage gemäß Anspruch 9 mit den jeweils kennzeichnenden Merkmalen gelöst.This object is achieved based on a stretching device for textile slivers according to the preamble of claim 1 and based on a stretching system according to claim 9 with the respective characterizing features.

Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Advantageous developments of the invention are specified in the dependent claims.

Die Erfindung schließt die technische Lehre ein, dass das Ablagegehäuse und die Grundplatte jeweils mehrteilig ausgebildet sind und dass das Ablagegehäuse und/oder die Grundplatte derart ausgesteift ausgebildet sind, dass die Streckvorrichtung in einem montierten Zustand transportierbar ist.The invention includes the technical teaching that the storage housing and the base plate are each designed in multiple parts and that the storage housing and/or the base plate are designed to be stiffened in such a way that the stretching device can be transported in an assembled state.

Die erfindungsgemäße Streckvorrichtung ist mit einem vergrößerten Ablagegehäuse und mit einer vergrößerten Grundplatte ausgebildet, sodass Ablagekannen mit einem Durchmesser von 1200 mm befüllt werden können. Die Vergrößerung des Ablagegehäuses sowie die Vergrößerung der Grundplatte ist erfindungsgemäß dadurch vorgenommen worden, dass die Grundplatte in eine größere Hauptplatte und in eine kleinere Seitenplatte unterteilt ausgebildet ist, ebenfalls ist das Ablagegehäuse in eine Hauptplatte und in eine Seitenplatte aufgeteilt. Die Seitenplatte an der Hauptplatte zur Bildung der Grundplatte befindet sich dabei auf einer gegenüberliegenden Seite zur Anordnung der Seitenplatte an der Hauptplatte zur Bildung des Ablagegehäuses.The stretching device according to the invention is designed with an enlarged storage housing and with an enlarged base plate, so that storage cans with a diameter of 1200 mm can be filled. The enlargement of the storage case and the enlargement of the base plate has been made according to the invention in that the base plate is divided into a larger main plate and a smaller side plate, the storage case is also divided into a main plate and a side plate. The side panel on the main panel to form the base panel is on an opposite side to the arrangement of the side panel on the main panel to form the storage case.

Insgesamt ergibt sich auch mit dem mehrteiligen Ablagegehäuse und mit der mehrteiligen Grundplatte eine derart ausgesteifte Konstruktion zur Bildung der Streckvorrichtung, dass die Streckvorrichtung trotz der vergrößerten Ausmaße in einem montierten Zustand als Ganzes transportierbar ist. Insbesondere die Verbindungen zwischen den jeweiligen Hauptplatten und Seitenplatten ist derart mechanisch belastbar ausgeführt, dass die Streckvorrichtung in einem Stück, das heißt in einem montierten Zustand, transportierbar ist.Overall, the multi-part storage housing and the multi-part base plate also result in such a stiffened construction for forming the stretching device that the stretching device can be transported as a whole in an assembled state despite the increased dimensions. In particular, the connections between the respective main plates and side plates are designed to be mechanically resilient in such a way that the stretching device can be transported in one piece, ie in an assembled state.

Der montierte Zustand der Streckvorrichtung, in dem diese noch transportierbar ist, bildet insbesondere einen Zustand, in dem die Streckvorrichtung im Wesentlichen einsatzfertig ausgebildet ist. Die Streckvorrichtung kann somit an einen Einsatzort transportiert werden, beispielsweise als Teil einer Doppel-Streckanlage, die eine erste und eine zweite Streckvorrichtung umfasst.The mounted state of the stretching device, in which it can still be transported, forms in particular a state in which the stretching device is designed essentially ready for use. The stretching device can thus be transported to a place of use, for example as part of a double stretching system which comprises a first and a second stretching device.

Gemäß eines weiteren Aspektes der Erfindung weist die Grundplatte eine Hauptplatte und eine Seitenplatte auf, sodass die Grundplatte eine Breite umfasst, über die wenigstens eine Ablagekanne mit einem Durchmesser von 1200 mm aufnehmbar ist.According to a further aspect of the invention, the base plate has a main plate and a side plate, so that the base plate has a width over which at least one storage can with a diameter of 1200 mm can be accommodated.

Dabei ist wenigstens eine Säule mit der Hauptplatte und wenigstens eine Säule mit der Seitenplatte der Grundplatte verbunden. Beispielsweise weist die Grundplatte eine erste Seitenkante auf, über der drei Säulen beabstandet zueinander auf der Grundplatte aufgenommen sind. Auf der gegenüberliegenden Seitenkante sind zwei Säulen auf der Grundplatte befestigt, und eine weitere, dritte Säule, befindet sich in Anordnung an einer Hinterkante der Grundplatte.At least one column is connected to the main plate and at least one column is connected to the side plate of the base plate. For example, the base plate has a first side edge, above which three columns are accommodated on the base plate at a distance from one another. On the opposite side edge, two pillars are fixed to the base plate and another, third pillar, is located at a rear edge of the base plate.

Gemäß eines weiteren Aspektes der Erfindung weist das Ablagegehäuse wenigstens drei Plattensegmente auf, die zur Bildung einer rechteckförmigen Hauptplatte miteinander verbunden sind, und wobei das Ablagegehäuse eine Seitenplatte aufweist, die an einer Seitenkante der Hauptplatte angeordnet ist, sodass wenigstens ein vorderer Bereich des Ablagegehäuses eine Breite umfasst, über die eine Ablagekanne mit einem Durchmesser von 1.200 mm aufnehmbar ist. Die Anordnung der Säulen an dem Ablagegehäuse kann dabei so vorgesehen sein, dass zwei Säulen an der Seitenplatte angeordnet sind und drei Säulen sind an einer gegenüberliegenden Längskante der Hauptplatte des Ablagegehäuses angeordnet. Eine weitere Säule kann dabei an einer Hinterkante der Hauptplatte angebracht sein.According to a further aspect of the invention, the storage case has at least three panel segments which are joined together to form a rectangular main panel, and wherein the storage case has a side panel which is arranged on a side edge of the main panel so that at least a front region of the storage case has a width includes, about the one Storage pot with a diameter of 1,200 mm can be accommodated. The arrangement of the columns on the storage case can be provided such that two columns are arranged on the side panel and three columns are arranged on an opposite longitudinal edge of the main panel of the storage case. A further column can be attached to a rear edge of the main plate.

Gemäß eines weiteren Vorteils sind die Säulen derart zwischen dem Ablagegehäuse und der Grundplatte angeordnet, dass seitliche Öffnungsbereiche gebildet sind, durch die eine Hebegabel eines Hebegerätes in den Zwischenraum zwischen dem Ablagegehäuse und der Grundplatte einfahrbar ist, um die Streckvorrichtung mittels eines Untergriffes unter das Ablagegehäuse anzuheben. Insbesondere die Verbindungen der einzelnen Plattenteile, aus denen die Hauptplatte des Ablagegehäuses ausgebildet ist, sind so steif und mechanisch belastbar ausgeführt, dass das Gewicht der Streckvorrichtung, das mehr als 1,5 Tonnen beträgt, je nach Ausführung bis zu 1,8 Tonnen, über einen Untergriff unter das Ablagegehäuse angehoben werden kann, ohne dass das mehrteilige Ablagegehäuse Schaden nimmt. Gemäß einer weiteren Möglichkeit zum Transport der Streckvorrichtung ist auch die Grundplatte mit der Hauptplatte und der Seitenplatte derart ausgesteift ausgebildet, dass das Hebegerät mit der Hebegabel unter die Grundplatte greifen kann. Hierzu kann hilfsweise ein Transportrahmen oder eine Transportplatte Verwendung finden, um die Last auf einen größeren Bereich der Grundplatte zu verteilen.According to a further advantage, the columns are arranged between the storage housing and the base plate in such a way that lateral opening areas are formed through which a lifting fork of a lifting device can be moved into the space between the storage housing and the base plate in order to lift the stretching device by means of a grip underneath the storage housing . In particular, the connections between the individual plate parts that make up the main plate of the storage case are designed to be so stiff and mechanically resilient that the weight of the stretching device, which is more than 1.5 tons, can be up to 1.8 tons, depending on the design a handle under the storage case can be raised without damaging the multi-part storage case. According to a further possibility for transporting the stretching device, the base plate with the main plate and the side plate is designed to be stiffened in such a way that the lifting device can reach under the base plate with the lifting fork. A transport frame or a transport plate can be used to distribute the load over a larger area of the base plate.

Auch ist es denkbar, dass die Hauptplatte und die Seitenplatte zur Bildung der Grundplatte Schraubbohrungen aufweisen, in die Schraubelemente einschraubbar sind, um an den Ecken der mit der Hauptplatte und mit der Seitenplatte gebildeten Grundplatte sogenannte Hubwinden zum Transport der Streckvorrichtung anzuordnen.It is also conceivable that the main plate and the side plate to form the base plate have screw holes into which screw elements can be screwed in order to arrange so-called lifting jacks for transporting the stretching device at the corners of the base plate formed with the main plate and the side plate.

Gemäß einer Weiterbildung der Streckvorrichtung ist eine Box zur Aufnahme von Betriebseinrichtungen der Streckvorrichtung an der Hinterseite der Streckvorrichtung an zwei Säulen hängend aufgenommen. Die Anordnung der Box beeinflusst folglich nicht die Steifigkeit der Streckvorrichtung, die im Wesentlichen durch die ausgesteifte Grundplatte und das ausgesteifte Ablagegehäuse gebildet ist. Die Steifigkeit wird insbesondere dadurch verbessert, dass die Seitenplatten der Grundplatte und des Ablagegehäuses an jeweils gegenüberliegenden Hauptkanten der Hauptplatten angeordnet sind.According to a development of the stretching device, a box for accommodating operating equipment of the stretching device is accommodated hanging on two columns at the rear of the stretching device. Consequently, the arrangement of the box does not affect the rigidity of the stretching device, which is essentially formed by the stiffened base plate and the stiffened storage housing.
