Abstract

A water needling device has a housing having an intake side and defining a generally horizontal transport direction extending downstream from the intake side. A support in the housing has an upwardly directed foraminous support face. Upstream and downstream reversible winders in the housing spaced apart in the direction flank a plurality of rollers. A textile web passesin the housing along a path starting at the intake, extending over the support face and the rollers, and then downstream out of the housing. A nozzle beam is directed downward at the surface to consolidate the web as it passes over the foraminous face. A threading-in conveyor strand secured to the winders and having a gripper attachable to the textile web extends over at least some of the rollers. This strand is attached at its ends to reversible winders.

Description

WasservernadeiungsvorrichtungWasservernadeiungsvorrichtung
Eine hydrodynamische Vernadelungsvorrichtung ist allgemein bekannt. Sie ist im Oberbegriff des ersten Anspruchs wiedergegeben. Übliche dort angeordnete Endlosbänder oder die eigentliche Vernadelungstrommel sind selbsteinfädelnd für die neu zulaufende Warenbahn, die Warenbahn ist nur an die jeweilige Walze anzulegen, dann sollte der Weitertransport der Warenbahn automatisch fortfahren. Es gibt aber auch Vorrichtungen dieser Art, die nicht nur sehr groß in ihren Höhenmaßen sind, so dass eine Bedienungsperson die einzelnen Warenbahnförderelemente nicht mehr erreicht, und/oder die Warenbahn kann eine Breite aufweisen, die nur schlecht manipulierbar ist. Mehrere Personen müssen beim Einfä- dein der Warenbahn behilflich sein, auch müssen sie über ein Gerüst die notwendige Einführhöhe ersteigen.A hydrodynamic needling apparatus is well known. It is reproduced in the preamble of the first claim. Usual arranged there endless belts or the actual needling drum are selbsteinfädelnd for the newly tapered web, the web is only to create the respective roller, then the onward transport of the web should continue automatically. But there are also devices of this kind, which are not only very large in their height dimensions, so that an operator no longer reaches the individual web conveyor elements, and / or the web may have a width that is difficult to manipulate. Several persons have to assist in the insertion of the web, and they also have to climb the necessary insertion height via a scaffold.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu entwi¬ ckeln mit der eine Warenbahn automatisch, im wesentlichen ohne Hilfe einer Bedienungsperson über einzelne oder alle Umlenkwalzen gelegt werden kann.The object of the invention is to develop a device by means of which a web can be laid automatically, essentially without the assistance of an operator, via individual or all deflection rollers.
Ausgehend von der Vorrichtung gemäß Oberbegriff wird die gestellte Aufgabe dadurch gelöst, dass für den Start der Vorrichtung, zum Einzug der Warenbahn über die einzelnen Walzen der Gesamt- oder nur einzel¬ ner Teile der Vorrichtung eine Warenbahneinzugs-Hilfsvorrichtung vor¬ gesehen ist. Die . Einfädelvorrichtung kann eine eigene unabhängig von den Elementen der Vernadelungsvorrichtung vorgesehene Konstruktion haben oder sie kann an den sowieso vorgesehenen Walzen für die Füh- rung der Warenbahn gelagert sein. Zweckmäßigerweise dient zur Einfä- delung lediglich ein eindimensionaler Förderer, der mit einer Befesti¬ gungsvorrichtung für die Warenbahn zum Einfädeln angetrieben vorläuft und dann für einen neuen Einsatz reversibel wieder zurück zum Einlauf gezogen wird.Based on the device according to the preamble, the stated object is achieved in that for the start of the device, for the collection of the web over the individual rolls of the total or only einzel¬ ner parts of the device a web-infeed auxiliary device is vor¬ seen. The . Threading device may have its own provided independently of the elements of the needling device construction or it may be stored on the rollers provided anyway for the guidance of the web. Expediently, only one-dimensional conveyor used for threading is used, which runs ahead with a fastening device for the material web for threading and then reversibly pulled back to the inlet for a new use.
Eine Vorrichtung der erfindungsgemäßen Art ist in der Zeichnung bei- spielhaft dargestellt. Die Figur zeigt eine Wasservernadelungsvorrich- tung mit zwei Vernadelungsstationen und in diesem Fall dann zwei Ein- fädelvorrichtungen.A device of the type according to the invention is shown by way of example in the drawing. The figure shows a water needling device with two needling stations and in this case two threading devices.
In einem Gehäuse 1 sind gemäß Beispiel die beiden Vernadelungsstati- onen A und B angeordnet. Sie bestehen jeweils aus einer Siebtrommel 2,In a housing 1, the two needling stations A and B are arranged according to the example. They each consist of a screening drum 2,
3, die gegen Uhrzeigersinn angetrieben umlaufen. Den Siebtrommeln 2,3, circulating driven counterclockwise. The sieve drums 2,
3 sind oberhalb mehrere Düsenbalken 4 radial zugeordnet und in dem3 are assigned above a plurality of nozzle beam 4 radially and in the
Gehäuse 1 ortsfest gelagert. Innerhalb der Siebtrommeln sind in Höhe der aus den Düsenbalken austretenden Düsenstrahlen Absaugvorrich- tungen vorgesehen, die hier aber nicht dargestellt sind.Housing 1 stored stationary. Within the sieve drums suction devices are provided at the level of the nozzle jets emerging from the nozzle beams, which are not shown here.
Die Warenbahn läuft in die Vernadelungsvorrichtung in Richtung des Pfeils 6 in der grundsätzlichen Warentransportrichtung ein, und zwar auf dem Endlosband 7 liegend, dessen oberes Trum tangential an der Unter- seite der Siebtrommel 2 anliegt. Anschließend umschlingt die Waren¬ bahn 5 die Siebtrommel 2 um mehr als 180° und wird in Höhe des Ein- laufs mittels einer Umlenkwalze 8 nach oben umgelenkt. Dort sind drei weitere Umlenkwalzen 9 im Gehäuse 1 oberhalb der Siebtrommel 2 drehbar gelagert, die die Warenbahn 5 wieder zurück in Richtung der grundsätzlichen Warentransportrichtung umlenken und tragen. Es folgt eine gleiche Vernadelungsstation B mit der Siebtrommel 3, die bei die¬ sem Ausführungsbeispiel wiederum gegen Uhrzeigersinn umläuft und auf der wiederum die bereits vernadelte Seite der Warenbahn 5 von den Dü¬ senstrahlen beaufschlagt wird. In Folge sind auch dort ähnlich angeord- nete Umlenkwalzen 8' und oberhalb der Siebtrommel 3 die Walzen 9' drehbar gelagert, um die vernadelte Warenbahn 5' in Transportrichtung 6 aus der Vorrichtung entfernen zu können. !m Ausführungsbeispiel sind die Siebtrommeln 2, 3 in Arbeitshöhe der Bedienungsperson angeordnet. Deshalb ist dort das Einfädeln der Wa¬ renbahn 5 leicht zu tätigen. Anders ist die Rückführung der Warenbahn von der Umlenkwalze 8 über die Walzen 9 hin zu der Ablaufwalze 10 jetzt wieder in Höhe der Siebtrommel 3, an der die Warenbahn wieder von der Bedienungsperson ergriffen werden kann. Die Walzen 9 sind im Gehäuse 1 schwer zugänglich und je nach Größe der Gesamtvorrichtung weit oberhalb der Reichweite der Bedienungsperson angeordnet. Aus diesem Grund ist in diesem Ausführungsbeispiel eine Einfädelvorrichtung nur für die oberen Umlenkwalzen 9 dargestellt.The web enters the needle-punching device in the direction of the arrow 6 in the basic goods transport direction, lying on the endless belt 7, whose upper run lies tangentially against the underside of the screen drum 2. Subsequently, the web 5 wraps around the screening drum 2 by more than 180 ° and is deflected upwards at the level of the inlet by means of a deflection roller 8. There, three further guide rollers 9 are rotatably mounted in the housing 1 above the screen drum 2, which redirect the web 5 back in the direction of the fundamental goods transport direction and carry. This is followed by a same needling station B with the screening drum 3, which in turn rotates counterclockwise in this embodiment and on which in turn the already needled side of the material web 5 is acted upon by the nozzle jets. As a result, similarly arranged deflecting rollers 8 'and above the screening drum 3, the rollers 9' rotatably mounted in order to remove the needled web 5 'in the transport direction 6 from the device can. In the exemplary embodiment, the sieve drums 2, 3 are arranged at the operating height of the operator. Therefore, there threading the Wa¬ renbahn 5 is easy to make. Unlike the return of the web from the guide roller 8 via the rollers 9 to the drain roller 10 is now back to the level of the screen drum 3, where the web can be taken again by the operator. The rollers 9 are difficult to access in the housing 1 and, depending on the size of the overall device, are arranged far above the reach of the operator. For this reason, a threading device is shown only for the upper guide rollers 9 in this embodiment.
Eine ähnliche oder anders aufgebaute Einfädelvorrichtung kann auch für die Einfädelung der Warenbahn in die ganze Vernadelungsvorrichtung mit den Stationen A und B eingebaut sein. Diese könnte automatisch o- der halbautomatisch tätig werden. Eine vollautomatische Einfädelvorrich¬ tung könnte aus einem Vorläufer bestehen, der vor der Vernadelungsvor¬ richtung mit einem zusätzlichen Wasservemadelungsbalken an der Wa¬ renbahn vollflächig befestigt wird und der dann mittels Seile, mittels scherenförmig den Vorläufer ergreifender und führender Seile die Wa- renbahn um alle Walzen, Umlenkwalzen, entlang von Bändern od. dgl. genau wie bei der zur Vernadelung vorgesehenen Warenbahnführung führt und sogar die Warenbahn in den meist folgenden Trockner einfä¬ deln kann.A similar or differently constructed threading device can also be installed for the threading of the fabric web in the entire needling device with the stations A and B. This could be automatic or semi-automatic. A fully automatic threading device could consist of a precursor, which is fastened over the full surface before the needling device with an additional water-loading bar on the fabric track, and then the web around all rolls by means of ropes, by means of scissors-like precursors of moving and leading ropes , Deflection rollers, along bands or the like, just as in the case of the needling line provided for web guiding leads and even the web can einfä¬ in the dryer most often following.
Zum Einzug der Warenbahn kann ein Überführungsband, eine Kette oder ein Seil zum Einsatz kommen. Für den Antrieb dieser Elemente für den Einzug der Warenbahn ist wichtig, die Warenbahn mit konstantem Dreh¬ moment, mit konstanter Zugkraft einzufädeln. Dies kann manuell, mit ei¬ nem Elektro- oder Pneumatikmotor, mit einem Drehmagnet oder mit Tor- sionsfedern erfolgen.For the collection of the web, a transfer belt, a chain or a rope can be used. For the drive of these elements for the entry of the web is important to thread the web with constant torque, with constant pulling force. This can be done manually, with an electric or pneumatic motor, with a rotary magnet or with torsion springs.
In vorliegendem Fall ist für die Einfädelung der Warenbahn 5 ein rever¬ sibler linienförmiger Förderer 11 vorgesehen mit in Höhe der Umlenkwal- zen 9 im Gehäuse 1 angeordnetem, reversibel antreibbarem Winder 12, von dem der Förderer 1 1 wie z. B. ein Seil nach unten um eine in Höhe der Siebtrommel 2 angeordnete Umlenkwalze 13 geführt ist. Dort ist in dem aufwärts laufenden Trum des Förderers 11 eine für die einzu- ziehende Warenbahn 5 lösbare Befestigungsvorrichtung 14 angeordnet, die hier als eine Seilschlaufe dargestellt ist. Jede andere Befestigung wie eine vorher erfolgte Verbindung der Warenbahn mit ggf. einem Vorläufer, ein Klettverschluss, ein einfacher Haken, Ösen oder ähnliche Elemente können hier zum Einsatz kommen. Jedenfalls wird hier die einzuziehen- de Warenbahn 5 an dem Förderer befestigt und durch den Zug des För¬ derers von einem reversiblen Winder 15 unterhalb der Ablaufwalze 10 über die Umlenkwalzen 9 gezogen.In the present case, a rever¬ sibler linear conveyor 11 is provided for the threading of the web 5 with in the amount of Umlenkwal- zen 9 arranged in the housing 1, reversibly driven winder 12, of which the conveyor 1 1 such. B. a rope down to a height of the screen drum 2 arranged guide roller 13 is guided. There, in the upwardly running run of the conveyor 11, a fastening device 14 that is detachable for the web 5 to be pulled in is arranged, which is shown here as a loop of cable. Any other attachment such as a previously made connection of the web with possibly a precursor, a hook and loop fastener, a simple hook, eyelets or similar elements can be used here. In any case, here the web 5 to be drawn in is fastened to the conveyor and pulled by the train of the conveyor by a reversible winder 15 below the run-off roller 10 over the guide rollers 9.
Nach Lösen der Warenbahn von dem Förderer 11 in Höhe der Ablauf- walze 10 wird die Warenbahn 5 von der Bedienungsperson wieder er- fasst und um die Siebtrommel 3 der nachfolgenden Vernadelungsstation B geführt. Für diese folgende Vernadelungsstation ist die gleiche Einfä¬ delvorrichtung mit der gleichen Arbeitsweise vorgesehen, weswegen in der Zeichnung gleiche Bezugszeichen angegeben sind.After loosening the web from the conveyor 11 at the level of the discharge roller 10, the web 5 is detected again by the operator and guided around the screen drum 3 of the subsequent needling station B. For this following Vernadelungsstation the same Einfä¬ delvorrichtung is provided with the same operation, which is why the same reference numerals are indicated in the drawing.
Die Warenbahn kann eine schmale, aber auch eine große Breite von mehr als 5 m aufweisen. Bei großen Breiten ist es vorteilhaft, den Anfang der Warenbahn in der Breite zu verkleinern. Der hier vorgesehene Li¬ nienförderer 11 ist an der einen Seite der Walzen 2, 3, 8, 9 10 angeord- net und dort in einer kleinen Verbreiterung der Walzen an deren Außen¬ umfang geführt. The web may have a narrow, but also a large width of more than 5 m. For large widths, it is advantageous to shrink the beginning of the web in width. The belt conveyor 11 provided here is arranged on one side of the rollers 2, 3, 8, 9 and there guided in a small widening of the rollers on the outer periphery thereof.
