Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung eines Faservlieses aus vertikal gefaltetem Faserflor der im jeweiligen Oberbegriff der Patentansprüche 1 und 5 angegebenen Gattungen.The invention relates to a method and a device for producing a nonwoven fabric from vertically folded fibrous web of the genera specified in the respective preamble of claims 1 and 5.

Es ist allgemein bekannt, daß die Eigenschaften von textilen Flächengebilden wesentlich von deren Struktur und insbesondere von der Orientierung der Fasern im Textilmaterial bestimmt werden. Diese Faserorientierung beeinflußt sowohl die Verformungseigenschaften des Textilmaterials sowie dessen Durchlässigkeit für Gase und Flüssigkeiten und die Isoliereigenschaften gegen Wärme und Geräusche.It is generally known that the properties of textile fabrics are essentially determined by their structure and in particular by the orientation of the fibers in the textile material. This fiber orientation influences both the deformation properties of the textile material as well as its permeability to gases and liquids and the insulating properties against heat and noise.

Aus der EP-A-0 350 627, Fig. 2 ist eine gattungsgemäße Vorrichtung bekannt, bei welcher der Faserflor vertikal einer Formiereinrichtung zugeführt wird, die einen drehangetriebenen und mit Stauchdornen besetzten Arbeitszylinder aufweist. Die Stauchdorne sind entgegen der Drehrichtung, d.h. nach rückwärts gebogen und greifen zwischen die Zinken eines oberen horizontalen Leitelements, das mit dem Obertrum eines Bandförderers einen Spaltraum begrenzt, in dem das aus dicht nebeneinander liegenden vertikalen Lamellen gebildete Faservlies erzeugt und in Austragsrichtung abgefördert wird. Im Einlaufbereich des Arbeitszylinders ist eine Stößelanordnung vorgesehen, deren hin- und herbewegbarer Stößel bei jeder Vorschubbewegung in einen Zwischenraum zwischen benachbarten Stauchdornen eindringt und dabei den an einer Leitwand tangential zum Flugkreis der Stauchdorne zugeführten Faserflor zur Bildung einer Falte in diesen Zwischenraum hineinschiebt. Durch die Drehbewegung des Arbeitszylinders und die nach rückwärts gebogene Form der Stauchdorne werden diese Falten in den Spaltraum zwischen dem kammartigen Leitelement und dem unteren Fördertrum hineingeschoben und zu den aufrechten Lamellen geformt. Aufgrund der zur Ebene des Faservlieses senkrechten Orientierung der Lamellen wird eine hohe Bauschigkeit und hohe Damm- bzw. Isolier-Eigenschaften erzielt. Wegen der notwendigen hinund hergehenden Bewegungen des Stößels ist die Leistungsfähigkeit dieser Vorrichtung jedoch begrenzt.From EP-A-0 350 627, Fig. 2, a generic device is known, in which the fibrous web is fed vertically to a forming device which has a rotationally driven working cylinder equipped with compression mandrels. The compression mandrels are counter to the direction of rotation, ie they are bent backwards and engage between the tines of an upper horizontal guide element which, with the upper run of a belt conveyor, delimits a gap in which the nonwoven fabric formed from closely spaced vertical lamellae is produced and removed in the discharge direction. A plunger arrangement is provided in the inlet area of the working cylinder, the plunger of which can be moved back and forth with each feed movement penetrates into an intermediate space between adjacent compression mandrels and thereby pushes the fiber web fed tangentially to the flight circle of the compression mandrels into this intermediate space to form a fold. Due to the rotary movement of the working cylinder and the backward-curved shape of the compression mandrels, these folds are pushed into the gap between the comb-like guide element and the lower conveyor run and formed into the upright lamellae. Due to the orientation of the lamellae perpendicular to the plane of the nonwoven fabric, a high bulk and high dam and insulation properties are achieved. However, the performance of this device is limited due to the necessary reciprocating movements of the ram.

Aus der CS-A-273 997 ist eine ähnliche Vorrichtung zur Herstellung eines aus vertikalen Florlamellen bestehenden Faservlieses bekannt, die als Formiereinrichtung zum Falten des vertikal zugeführten Faserflors ebenfalls einen Arbeitszylinder und eine Leitwand enthält, deren unterer bogenförmiger Teil etwa tangential zum Flugkreis der nach rückwärts gebogenen Stauchdorne verläuft. Durch die Drehbewegung des Arbeitszylinders und der Stauchdorne wird der vertikal zugeführte Faserflor von den Stauchdornspitzen ergriffen und in Form von vertikalen Falten in den Spaltraum zwischen dem Obertrum eines Bandförderers und einem oberen kammartigen Leitelement geschoben. Die Stauchung der Florfalten zu den dicht nebeneinander liegenden Lamellen erfolgt aufgrund der Vorschubbewegung im Spaltraum.From CS-A-273 997 a similar device for producing a fiber fleece consisting of vertical pile lamellae is known, which also contains a working cylinder and a guide wall as a forming device for folding the vertically fed fiber pile, the lower arcuate part of which is approximately tangential to the flight circle or to the rear curved compression mandrels. As a result of the rotary movement of the working cylinder and the compression mandrels, the vertically fed fiber web is gripped by the tips of the compression mandrel and pushed in the form of vertical folds into the gap between the upper run of a belt conveyor and an upper comb-like guide element. The pile folds are compressed to the lamellae lying close together because of the feed movement in the gap space.

Schließlich ist aus der FR-A-1 195 940 ein Verfahren und eine Vorrichtung zur Herstellung eines Faservlieses mit im wesentlichen vertikal orientierten Einzelfasern bekannt, die eine aus Förderbändern bestehende Zuführeinrichtung für ein wirres Faserflor sowie eine mit Drähten bzw. Stacheln besetzte Arbeitswalze aufweist, welche von einer sich über einen Teil ihres Umfanges erstreckenden Leitwand umgeben ist. Die in Förderrichtung, d.h. nach vorn, gerichteten Stacheln erfassen die zugeführten Einzelfasern und schleudern sie in den Einlaufbereich zwischen einer oberen Walze und einem unteren Bandförderer. Eine gewisse Orientierung der Fasern in vertikaler Richtung wird durch einen Luftstrom erreicht, der etwa tangential am Auslaßbereich des Arbeitszylinders zum Einlaufbereich der Austragseinrichtung gerichtet ist.Finally, from FR-A-1 195 940 a method and a device for producing a nonwoven fabric with essentially vertically oriented individual fibers is known, which has a feed device consisting of conveyor belts for a tangled fibrous web and a work roll fitted with wires or spikes, which is surrounded by a guide wall extending over part of its circumference. The spines directed in the conveying direction, ie forward, grasp the supplied individual fibers and fling them into the entry area between an upper roller and a lower belt conveyor. A certain orientation of the fibers in the vertical direction is achieved by an air stream which is directed approximately tangentially at the outlet region of the working cylinder to the inlet region of the discharge device.

Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zur Herstellung eines Faservlieses aus vertikal gefaltetem Faserflor zu schaffen, die bei zwangsweiser Einspeisung des Faserflors oder ggf. anderer Flächengebilde maximale Zuführgeschwindigkeiten des Faserflors und die Bildung von Lamellen mit genau definierten Größen und Formen ermöglicht.The object of the invention is to provide a method and an apparatus for producing a nonwoven fabric from vertically folded fiber web, which, when the fiber web or possibly other sheet material is forcibly fed in, enables maximum feed speeds of the fiber web and the formation of lamellae with precisely defined sizes and shapes.

Diese Aufgabe wird erfindungsgemäß durch die in den Patentansprüchen 1 bzw. 5 angegebenen Maßnahmen und Merkmale gelöst.This object is achieved according to the invention by the measures and features specified in patent claims 1 and 5.

Die Vorrichtung gemäß der Erfindung enthält eine Zuführeinrichtung, die Zuführscheiben mit angerauhter Oberfläche besitzt, welche zwischen die Stauchdorne des Arbeitszylinders eingreifen. Die Form der Stauchdorne wird so gewählt, daß die Spalte zwischen der Druckseite und der abgewandten Seite die maximale Florlänge bestimmt, welche von den Zuführscheiben in diese Spalte eingebracht werden kann. Diese zu Falten geformten Florlängen werden durch Einschieben in den Spaltraum zwischen dem als Förderer ausgebildeten Transportelement und dem kammförmigen Leitelement zu aufrechten Lamellen gestaucht. Dabei wird die zuletzt eingelegte Falte durch die konvex geformte Flanke des bogenförmigen Stauchdornes in diesen Spaltraum eingeschoben. Die Höhe der so gebildeten Lamelle kann durch das Verhältnis der Zuführgeschwindigkeit des Faserflors und der Umlaufgeschwindigkeit der Stauchdorne geregelt werden.The device according to the invention contains a feed device which has feed discs with a roughened surface which engage between the compression mandrels of the working cylinder. The shape of the compression mandrels is chosen so that the gap between the pressure side and the opposite side determines the maximum pile length, which can be introduced into this column by the feed discs. These pile lengths are formed into folds by being pushed into the gap between the conveyor trained transport element and the comb-shaped guide element compressed to upright slats. The fold last inserted is pushed into this gap space by the convexly shaped flank of the arched compression mandrel. The height of the lamella formed in this way can be regulated by the ratio of the feed speed of the fiber web and the rotational speed of the compression mandrels.

Gemäß einer zweckmäßigen Ausgestaltung der Erfindung können die Schrägungswinkel der Lamellen im gebildeten Faservlies durch einen an der unteren Seite angebrachten Formgebungszylinder geregelt werden, dessen Dorne in Aussparungen in der bogenförmigen Leitwand 4 sowie auch in den Raum zwischen den Arbeitsscheiben eingreifen.According to an expedient embodiment of the invention, the helix angles of the lamellae in the nonwoven formed can be regulated by a shaping cylinder attached to the lower side, the spikes of which engage in recesses in the arcuate guide wall 4 and also in the space between the working disks.

Die in Fig. 1 dargestellte Vorrichtung zur Herstellung von Faserflor aus vertikal zugeführtem Faserflor 16 enthält einen aus Zuführscheiben 2 bestehenden Zuführzylinder 1 und eine bogenförmige Führungspfanne 3, an welche nach dem Klemmpunkt A eine Führungswand 4 angeschlossen ist, die zusammen mit einem Kamm 8 und einem Transportband 11 der Heißluftkammer einen Spaltraum bildet, in welchen mittels Stauchdorne 7 an Arbeitsscheiben 6 eines Arbeitszylinders 5 die Lamellen 17 aus dem Faserflor 16 eingelegt werden. Die Stauchdorne 7 der Arbeitsscheiben 6 werden gemäß Evolventen geformt, deren Ausgangspunkte eine Gerade verbindet. Der Halbmesser der Grundkreislinie der Evolvente, welche die äußere Arbeitskante des Arbeitsdornes 7 umschreibt, ist kleiner als der Halbmesser der Grundkreislinie jener Evolvente, die einen Teil der inneren Kante des Arbeitsdornes 7 umschreibt. In diesem konkreten Fall ist oberhalb des Raumes des Eindringens der Zuführscheiben 2 und der Arbeitsdorne 7 der Arbeitsscheiben 6 des Arbeitszylinders 5 eine Vorrichtung 14 zum Auftragen von pulverförmigem Bindemittel angebracht, welches teilweise im ausgeformten Vlies steckenbleibt und teilweise auf eine Textilie 15 fällt, die vom Transportband 11 der Heißluftkammer getragen wird. Es entsteht so ein Textilgebilde aus Vlies und einer auf der unteren Kante angeklebten Textilie 15.The device shown in FIG. 1 for the production of fiber web from vertically fed fiber web 16 contains a feed cylinder 1 consisting of feed disks 2 and an arcuate guide pan 3, to which a guide wall 4 is connected after the clamping point A, which together with a comb 8 and a Conveyor belt 11 of the hot air chamber forms a gap in which the lamellae 17 from the fiber web 16 are inserted by means of compression mandrels 7 on working disks 6 of a working cylinder 5. The compression mandrels 7 of the working disks 6 are shaped according to involutes whose starting points connect a straight line. The radius of the base line of the involute, which circumscribes the outer working edge of the working mandrel 7, is smaller than the radius of the base circular line of that involute, which circumscribes part of the inner edge of the working mandrel 7. In this specific case, a device 14 for applying powdered binder is attached above the space of the penetration of the feed disks 2 and the working mandrels 7 of the working disks 6 of the working cylinder 5, which binder partly gets stuck in the formed nonwoven and partly falls onto a textile 15 falling off the conveyor belt 11 the hot air chamber is worn. This creates a textile structure made of fleece and a textile 15 glued to the lower edge.

Die in Fig. 2 dargestellte Vorrichtung von Faservlies aus vertikal zugeführtem Faserflor 16 enthält einen Zuführzylinder 1, welcher aus Zuführscheiben 2 besteht, sowie eine Zuführpfanne 3, an welche hinter dem Klemmpunkt A die Führungsfläche 4 angeschlossen ist, welche gemeinsam mit dem Kamm 8 und dem Förderer 11 der Warmluftkammer einen Spaltraum bildet, in den mittels der Stauchdorne 7 der Arbeitsscheiben 6 des Arbeitszylinders 5 die Lamellen 17 aus dem Faserflor 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 Dorne 13 eines Formgebungszylinders 12 eintreten, welche die Endstellung der Lamellen 17 im entstandenen Gebilde regulieren.The device shown in Fig. 2 of nonwoven fabric from vertically fed fiber pile 16 contains a feed cylinder 1, which consists of feed discs 2, and a feed pan 3, to which behind the clamping 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 gap, in which the compression mandrels 7 Working discs 6 of the working cylinder 5, the fins 17 are inserted from the batt 16. In this specific embodiment, the guide surface 4 is provided with grooves through which mandrels 13 of a shaping cylinder 12 enter the space between the comb 8 and the guide surface 4, which regulate the end position of the lamellae 17 in the structure formed.

Die in Fig. 3 gezeigte Vorrichtung zur Herstellung von Faservlies aus vertikal abgelagertem Faserflor 16 enthält einen aus Zuführscheiben 2 zusammengestellten Zuführzylinder 1 sowie eine Zuführpfanne 3, an welche hinter dem Klemmpunkt A die Führungsfläche 4 angeschlossen ist. Die bogenförmige Führungsfläche 4 bildet zusammen mit dem kammartigen Leitelement 8 und dem Förderer 11 einen Spaltraum, in welchen mittels Stauchdrähten 9 am Arbeitszylinder 5 die Lamellen 17 aus dem Faserflor 16 eingelegt werden. In diesem konkreten Fall sind die Stauchdrähte 9 elastisch, was deren elastische Verformung nach dem Anstoß an einer Leiste 10 ermöglicht, welche die Bahn der Stauchdrähte 9, auf welcher diese den Faserflor aus den Lamellen 17 verlassen, einstellt. Durch geeignete 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.The device shown in FIG. 3 for the production of nonwoven fabric from vertically deposited fibrous web 16 contains 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 arcuate guide surface 4 forms, together with the comb-like guide element 8 and the conveyor 11, a gap in which the slats 17 from the fiber web 16 are inserted by means of upsetting wires 9 on the working cylinder 5. In this specific case, the upsetting wires 9 are elastic, which enables their elastic deformation after abutment on a 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, the final inclination of the lamellae in the fibrous web is influenced, on the one hand, and on the other hand the accuracy of the shaping of the individual lamellae 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.

Die Vorrichtung ermöglicht die Herstellung von hochbauschigen Vliesstoffen und bildet zusammen mit einem hochleistungsfähigen Krempelsatz und einer Warmluftkammer eine Fertigungsstraße, deren technische sowie ökonomische Parameter die bisher bekannte Technik bedeutend übertreffen. Es werden dabei die Investitionskosten für die bebaute Fläche sowie für die Maschinen bedeutend herabgesetzt. Ferner verringert sich maßgebend der Energieanspruch sowie die Anzahl der für die Bedienung der Straße benötigten Arbeitskräfte.The device enables the production of high-bulk nonwovens and, together with a high-performance card set and a warm air chamber, forms a production line, the technical and economic lines of which Parameters significantly exceed the previously known technology. The investment costs for the built-up area and for the machines are significantly reduced. Furthermore, the energy demand and the number of workers required to operate the road are significantly reduced.
