Description

Bereich der TechnikArea of technology

Die vorliegende Erfindung betrifft eine Vorrichtung, die eine kontinuierliche Herstellung von Textilien ermöglicht, in denen der überwiegende Anteil der Fasern vertikal orientiert ist, d. h. überwiegend senkrecht zur Ebene der Textilie, und dadurch ermöglicht, eine grosse Bauschigkeit der Textilien und eine hiermit verbundene hohe Wärme- sowie Schallisolierungsfähigkeit zu erreichen. Die Vorrichtung ermöglicht, aus Flor sowie anderen Flächengebilden selbst bei ausserordentlich hohen Geschwindigkeiten eine präzis definierte Faserschichtstruktur zu bilden sowie, nach Wäremebehandlung, einen Vliesstoff mit neuen Gebrauchseigenschaften.The present invention relates to a device which enables continuous production of textiles in which the majority of the fibers are oriented vertically, i. H. predominantly perpendicular to the plane of the textile, and thereby makes it possible to achieve a high bulk of the textiles and a high heat and sound insulation capacity associated therewith. The device makes it possible to form a precisely defined fiber layer structure from pile and other flat structures even at extremely high speeds and, after heat treatment, a nonwoven fabric with new properties.

Bisheriger Stand der TechnikCurrent state of the art

Es ist allgemein bekannt, dass die Eigenschaften von textilen Flächengebilden in entscheidendem Mass von deren Struktur beeinflusst werden, wobei der Hauptparameter die Faserorientierung ist. Diese Orientierung beeinflusst sowohl die Verformungseigenschaften, als auch die von der Volumenmasse abhängigen Eigenschaften, die ausser Luft- und Flüssigkeitsdurchlässigkeit auch deren Wärme- und Geräuschisolierungsfähigkeiten sind.It is generally known that the properties of textile fabrics are decisively influenced by their structure, the main parameter being the fiber orientation. This orientation influences both the deformation properties and the properties dependent on the volume mass, which in addition to air and liquid permeability are also their heat and noise insulation capabilities.

Aus diesen Erwägungen entstand ein prinzipiell neues Herstellungsverfahren der Faserschicht, sowie der Vliesstoffe aufgrund von Floraufschichtung aus der Karde in Form von vertikal angeordneten Lamellen. Als Lamelle wird ein im Bogen angeordneter Abschnitt der Floraufschichtung, oder einer anderen Faserschicht bezeichnet, wie in Fig. 1 von dem mit der Bezugsziffer 17 bezeichneten Teil dargestellt wird. Zur Nutzung dieses Verfahrens, mittels welchen nicht nur hohe Bauschigkeit in Verbindung mit den begleitenden Funktionseigenschaften der Textilie, jedoch auch gute Beständigkeit gegenüber wiederholter Zusammendrückung erzielt wird, sind zwei grundlegende Verfahren sowie Vorrichtungen bekannt, die durch AO 269 300 und AO 273997 (AO=Urheberscheine) geschützt sind. Gemäss AO 269300 bildet die Vorrichtung eine Gruppe von zwei Texturierungselementen, und zwar eine Texturierungsleiste, die auf ihrem Arbeitsteil mit Spitzen versehen ist, sowie einer Stauchleiste, die in Längsrichtung mit Nadeln bestückt ist. Die Texturierungsleiste ist in ihrer Funktion dem Kamm zum Florabzug vom Zilinder der Karde analog, bewegt sich vertikal und zieht den vertikal zugeführten Faserflor zum Abführungsförderer ab, oberhalb welchem ein Rost angebracht ist. Bei der Rücklaufbewegung des Kammes fangen die Stauchnadeln der Leiste den Flor in der unteren Stellung auf, und die Leiste drückt durch ihre Horizontalbewegung den Faserflor in die Spalte zwischen den Förderer und den Rost. Die Abstimmung der Bewegung des Kammes und der Leiste macht es möglich, den Faserflor vertikal abzulegen und ein Vlies, bzw. eine Textilie mit einem überwiegenden Anteil von vertikal zur Ebene der Textilie orientierten Fasern zu bilden.Based on these considerations, a fundamentally new manufacturing process for the fiber layer, as well as the nonwovens due to pile layering from the card in the form of vertically arranged lamellae. A section of the pile layering or another fiber layer arranged in the arc is referred to as the lamella, as is shown in FIG. 1 by the part designated by the reference number 17. To use this method, by means of which not only high bulk in combination with the accompanying functional properties of the textile, but also good resistance to repeated compression is achieved, two basic methods and devices are known which are described in AO 269 300 and AO 273997 (AO = originals ) are protected. According to AO 269300, the device forms a group of two texturing elements, namely a texturing bar, on its working part is provided with tips, as well as a compression strip, which is equipped with needles in the longitudinal direction. The function of the texturing strip is analogous to that of the comb for drawing off the card from the cylinder, moves vertically and pulls the vertically fed fibrous web to the discharge conveyor, above which a grate is attached. During the return movement of the comb, the upsetting needles of the bar catch the pile in the lower position, and the bar, by means of its horizontal movement, presses the fibrous web into the gap between the conveyor and the grate. The coordination of the movement of the comb and the bar makes it possible to lay down the fiber pile vertically and to form a fleece or a textile with a predominant proportion of fibers oriented vertically to the plane of the textile.

Die zweite Vorrichtung, die in AO 273997 beschrieben wird, bildet ein mit geformten Spitzen aus gebogenem Draht, oder Ausschnitten aus Blechscheiben mit Verteilung in bestimmten Abständen bestückter Zylinder, sowie ein Rost mit einem zwischen den Spitzen geführtem System von Drähten, die über dem Förderer münden. Der von oben zugeführte Faserflor wird durch Drehung des Zylinders in den Kanal zwischen dem Transportband und dem horizontalen Teil des Rostes gestaucht.The second device, which is described in AO 273997, forms a cylinder equipped with shaped tips made of bent wire, or cutouts from sheet metal disks with distribution at certain intervals, and a grate with a system of wires guided between the tips, which lead out over the conveyor . The fiber web fed from above is compressed by rotating the cylinder into the channel between the conveyor belt and the horizontal part of the grate.

Beide Vorrichtungen, sowohl die gemäss AO 269300, als auch die gemäss AO 273997, sind imstande sowohl Vlies, als auch eine Textilie mit ungewöhnlicher Faserorientierung mit ausgesprochen hoher Bauschigkeit, sowie einer Reihe von vorteilhaften Funktionseigenschaften herzustellen. Beide haben jedoch ihre Nachteile, die es nicht gestatten, das Wesentliche auszunutzen, was eine einfache Zusammenstellung der Produktionslinie bietet. Das ist vor allem die Nutzung hochproduktiver florbildender Maschinen, von welchen die wirtschaftliche Effektivität der ganzen Fertigung abhängt. Eine auf dem Vibrationsprinzip gebaute Vorrichtung arbeitet verlässlich bei Florabzugs-Höchstgeschwidigkeiten von 100 m. min⁻¹. Das entspricht einer Schwingungszahl von ungefähr 1.500 Schwingungen pro Minute. Die Leistung der HöchstleistungsFlorbildner erreicht jedoch bis 450 kg . min⁻¹. Bei einer Flächenmasse von 20 g/m² würde dies mehr als 4.000 Schwingungen pro Minute erfordern. Bisher ist jedoch keine Lösung bekannt, welche diese Leistung durch Nutzung des beschriebenen Prinzips erreichen könnte.Both devices, both those in accordance with AO 269300 and those in accordance with AO 273997, are capable of producing both fleece and a textile with an unusual fiber orientation with extremely high bulk, as well as a number of advantageous functional properties. However, both have their disadvantages, which do not allow you to take advantage of the essentials, which offers a simple assembly of the production line. This is above all the use of highly productive pile-forming machines, on which the economic effectiveness of the entire production depends. A device built on the vibration principle works reliably at maximum pile take-off speeds of 100 m. min⁻¹. This corresponds to an oscillation number of approximately 1,500 oscillations per minute. However, the performance of the high-performance flora former reaches up to 450 kg. min⁻¹. With a basis weight of 20 g / m², this would be more than 4,000 vibrations per Require minute. So far, however, no solution is known which could achieve this performance by using the principle described.

Die Vorrichtung auf Rotationsprinzip gemäss AO 273997 hat andere Nachteile. Entscheidend ist der Umstand, dass die Abnahme und Abführung des Faserflors an dem Reibungsmass zwischen dem abzunehmenden Faserflor und der Oberfläche der Arbeitselemente, d.h. der geformten Drähte oder der Scheibenausschnitte abhängig ist. Bei deren glatter Oberfläche arbeitet die Vorrichtung verlässlich nur bei niedrigeren Geschwindigkeiten und einem niedrigeren Verdichtungsgrad. Beim Anrauhen der Oberfläche ist es möglich, die Geschwindigkeit der Fertigung zu erhöhen, mit zunehmender Geschwindigkeit kommt es jedoch zum Durchdringen der Fasern aus dem Faserflor des unteren Teils des Rostes bis zum Aufwickeln auf den rotierenden Zylinder. Ausserdem führt eine Vorrichtung dieser Konzeption zur Bildung von Lamellenanhäufungen unter einer bestimmten Abschrägung, sodass die Bildung eines vertikal geschichteten Vlieses und einer Textilie der Dicke von mehr als 15 mm nicht möglich ist. Deshalb ist diese Vorrichtung nur für Erzeugnisse von praktisch unterhalb 10 mm Dicke und zur Anwendung in einer Zusammenstellung mit Karden von einer Leistung bis 80 kg/St geeignet.The device based on the rotation principle according to AO 273997 has other disadvantages. The decisive factor is the fact that the removal and removal of the fibrous web depends on the mass of friction between the fibrous web to be removed and the surface of the working elements, i.e. the shaped wires or the disc cutouts. With its smooth surface, the device only works reliably at lower speeds and a lower degree of compaction. When the surface is roughened, it is possible to increase the speed of production, but with increasing speed, the fibers penetrate from the fibrous web of the lower part of the grate until they are wound onto the rotating cylinder. In addition, a device of this design leads to the formation of lamella accumulations under a certain slope, so that the formation of a vertically layered fleece and a textile with a thickness of more than 15 mm is not possible. Therefore, this device is only suitable for products of practically less than 10 mm thickness and for use in a combination with cards with a capacity of up to 80 kg / pc.

Wesen der ErfindungEssence of the invention

Das Wesen der Erfindung besteht in einer neuen Konstruktion des drehbaren Florlegers aus der Karde mit zwangsläufiger Florspeisung, gegebenenfalls Speisung anderer Flächengebilde, der den Betrieb bei maximaler bekannter Zuführungsgeschwindigkeit des Flors ermöglicht, sowie die Bildung genau definierter Grössen und Formen von Lamellen, welche die für die thermische Behandlung vorbereitete Faserschicht bilden. Es wird auch eine regelbare Lagerung der Lamellen unter verschiedenen Winkelmassen gemäss den Anforderungen an die Eigenschaften der Textilie ermöglicht.The essence of the invention consists in a new construction of the rotatable pile layer from the card with inevitable pile feed, possibly feeding other fabrics, which enables operation at the maximum known feed speed of the pile, as well as the formation of precisely defined sizes and shapes of lamellae which are suitable for the Thermal treatment form the prepared fiber layer. An adjustable storage of the slats under different angular masses is also made possible in accordance with the requirements for the properties of the textile.

Die Vorrichtung gemäss dem vorliegenden Patent bildet eine Zuführungsvorrichtung, die aus Zuführungsscheiben 2 mit angerauhter Oberfläche besteht, die in Fig. 1 und 2 dargestellt sind,und zwischen die Stauchdorne 7 der Arbeitsscheiben 6 des Arbeitszylinders 5 eingreifen. Die Form der Stauchdorne 7 wird derart gegewählt, dass die Spalte zwischen der Druckseite und der abgewendeten Seite die maximale Florlänge bestimmt, welche durch die Zuführungsscheiben in die Spalte eingebracht werden kann und welche bei Verschiebung zwischen den Förderer der Warmluftkammer 11 und den Rost 8 durch Zusammenlegung des Flors Lamellen bildet.
Die konvexe Flanke des Zahnes verschiebt sie, bzw. drückt sie an die vorgehenden, und bildet so eine Faserschicht. Die Höhe der Lamelle kann durch das Verhältnis der Zuführungsgeschwindigkeit des Flors 16 und die Umlaufgeschwindigkeit der Stauchdorne 7 geregelt werden. Zur Regelung eines grösseren oder kleineren Schrägungswinkels der Lamellen dient der von der unteren Seite angebrachte Formgebungszylinder 12 (Fig. 2), dessen einzelne Dorne 13 eine Einsparung in der Führungsfläche 4 in der Verlängerung der Zuführungspfanne 3 durchlaufen und in den Raum zwischen die Arbeitsscheiben 6 eintreten.The device according to the present patent forms a feed device which consists of feed disks 2 with a roughened surface, which are shown in FIGS. 1 and 2, and which engage between the compression mandrels 7 of the work disks 6 of the working cylinder 5. The shape of the compression mandrels 7 is selected such that the gap between the pressure side and the turned side determines the maximum pile length, which is determined by the Feeding disks can be introduced into the column and which, when displaced between the conveyor of the warm air chamber 11 and the grate 8, forms lamellae by merging the pile.
The convex flank of the tooth moves it or pushes it against the previous one, thus forming a fiber layer. The height of the lamella can be regulated by the ratio of the feed speed of the pile 16 and the rotational speed of the compression mandrels 7. The shaping cylinder 12 (FIG. 2) attached from the lower side serves to regulate a larger or smaller helix angle of the slats, the individual mandrels 13 of which pass through a saving in the guide surface 4 in the extension of the feed pan 3 and enter the space between the working disks 6 .

AusführungsbeispieleEmbodiments

In Fig. 1 ist eine Vorrichtung zur Schichtung von Flor 17 aus vertikal abgelagertem Faserflor 16 dargestellt, welche aus dem aus Zuführungsscheiben 2 bestehenden Zuführungszylinder 1, der Zuführungspfanne 3, an welche nach dem Klemmpunkt A die Führungsfläche 4 angeschlossen ist, die zusammen mit dem Kamm 8 und dem Transportband 11 der Heissluftkammer eine Spalte bildet, in welche mittels der Stauchdorne 7 der Arbeitsscheiben 6 des Arbeitszylinders 5 die Lamellen 17 aus Flor 16 eingelegt werden, besteht. Die Dorne 7 der Arbeitsscheiben 6 werden gemäss Evolventen geformt, deren Ausgangspunkte eine Gerade verbindet. Der halbmesser der Grundkreislinie der Evolvente, welche die äussere Arbeitskante des Dornes 7 umschreibt, ist kleiner als der halbmesser der Grundkreislinie jener Evolvente, die einen Teil der inneren Kante des Dornes 7 umschreibt. In diesem konkreten Fall ist oberhalb des Raumes des Eindringens der Zuführungsscheiben 2 und der Dorne 7 der Arbeitsscheiben 6 des Arbeitszylinders 5 eine Einstaubvorrichtung 14 zum Auftragen von pulverförmigem Bindemittel angebracht, welches teilweise im ausgeformten Vlies steckenbleibt, und teilweise auf die Textilie 15, die vom Transportband 11 der Heissluftkammer getragen wird, herabfällt. Es entsteht so ein Textil-gebilde, das aus Vlies mit einer auf der unteren Kante angeklebten Textilie 15 besteht. In Fig. 1 , a device for layering pile 17 from vertically deposited fiber pile 16 is shown, which consists of the feed cylinder 2 consisting of feed disks 2 , the feed pan 3 , to which after the clamping point A the guide surface 4 is connected, which together with the comb 8 and the conveyor belt 11 of the hot air chamber forms a column into which the slats 17 made of pile 16 are inserted by means of the compression mandrels 7 of the working disks 6 of the working cylinder 5 . The mandrels 7 of the working disks 6 are shaped according to involutes, the starting points of which connect a straight line. The radius of the base line of the involute, which circumscribes the outer working edge of the mandrel 7 , is smaller than the diameter of the base circle of the involute, which circumscribes part of the inner edge of the mandrel 7 . In this specific case, a dusting device 14 for applying powdered binder, which partly gets stuck in the formed nonwoven, and partly on the textile 15 , which is from the conveyor belt, is attached above the space where the feed disks 2 and the mandrels 7 of the working disks 6 of the working cylinder 5 penetrate 11 of the hot air chamber is worn, falls down. The result is a textile structure which consists of fleece with a textile 15 glued to the lower edge.

In Fig. 2 ist eine Vorrichtung zur Schichtung von Vlies aus vertikal abgelagertem Faserflor 16 dargestellt, die ein Zuführungszylinder 1 bildet, welcher aus Zuführungsscheiben 2 besteht, sowie eine Zuführungspfanne 3, an welche hinter dem Klemmpunkt A die Führungsfläche 4 angeschlossen ist, welche gemeinsam mit dem Kamm 8 und dem Förderer 11 der Warmluftkammer eine Spalte bildet, in welche mittels der Stauchdorne 7 der Arbeitsscheiben 6 des Arbeitszylinders 5 die Lamellen aus Flor 16 eingelegt werden. In dieser konkreten Ausführung ist die Führungsfläche 4 mit Nuten versehen, durch welche in den Raum zwischen dem Kamm 8 und der Führungsfläche 4 die Dorne 13 des Formgebungszylinders 12 eintreten, welche die Endstellung der Lamellen 17 im entstandenen Gebilde regulieren. In Fig. 2 , a device for layering nonwoven from vertically deposited fiber pile 16 is shown, which forms a feed cylinder 1 , which consists of feed discs 2 , and a feed pan 3 , to which behind the terminal point A, the guide surface 4 is connected, which together with the comb 8 and the conveyor 11 of the warm air chamber forms a column into which the slats of pile 16 are inserted by means of the compression mandrels 7 of the working disks 6 of the working cylinder 5 . In this specific embodiment, the guide surface 4 is provided with grooves through which the mandrels 13 of the shaping cylinder 12 enter the space between the comb 8 and the guide surface 4 and regulate the end position of the lamella 17 in the structure formed.

In Fig. 3 ist eine Vorrichtung zur Schichtung von Vlies aus vertikal abgelagertem Faserflor 16 dargestellt, die ein aus Zuführungsscheiben 2 zusammengestellterZuführungszylinder 1, sowie eine Zuführungspfanne 3, an welche hinter dem Klemmpunkt A die Führungsfläche 4 angeschlossen ist, bildet, wobei die Führungsfläche 4 zusammen mit dem Kamm 8 und dem Förderer 11 eine Spalte bildet, in welcher mittels der Stauchdrähte 9 des Arbeitszylinders 5 Lamellen aus Faserflor 16 eingelegt werden. In diesem konkreten Fall sind die Stauchdrähte 9 elastisch, was deren elastische Verformung nach dem Anstoss auf die Leiste 10 ermöglicht, welche die Bahn der Stauchdrähte 9, auf welcher diese den Faserflor aus den Lamellen 17 verlassen, einstellt. Durch geeignet gewählte Stellung der Leiste 10 wird einerseits die Endneigung der Lamellen im Faserflor, und andererseits die Genauigkeit der Formung der einzelnen Lamellen noch vor deren gegenseitigem Zusammendrücken in das Vlies beeinflusst. Weiters wird durch diese Ausführung gemäss Fig. 3 das Herausziehen einzelner Fasern aus dem Faserflor über den Kamm 8 hinaus verhindert. 3 shows a device for layering nonwoven from vertically deposited fiber pile 16 , which forms a feed cylinder 1 composed of feed disks 2 and a feed pan 3 to which the guide surface 4 is connected behind the clamping point A, the guide surface 4 together forms a column with the comb 8 and the conveyor 11 , in which 5 lamellae of fiber pile 16 are inserted by means of the strands 9 of the working cylinder. In this specific case, the upsetting wires 9 are elastic, which enables their elastic deformation after the abutment on the strip 10 , which adjusts the path of the upsetting wires 9 , on which they leave the fiber web from the lamellae 17 . By suitably chosen position of the strip 10 , on the one hand the final inclination of the slats in the fiber web, and on the other hand the accuracy of the shaping of the individual slats is influenced even before they are pressed together into the fleece. Furthermore, this embodiment according to FIG. 3 prevents individual fibers from being pulled out of the fibrous web beyond the comb 8 .
