Abstract

The particles containing cellulose and bonding agent are contained in a hopper (1) from where they are conveyed to an orienteering unit (4), via a unit (2), above the continuously moving base (10). The space between the orienteering unit and continuously moving base is higher than the upper side of the fibrous web being formed. The orienteering unit consists of several fan-shaped compartmented rollers (7) at right angles and contrary to the direction in which the base is continuously moving and spaced horizontally apart. The aligning surfaces (8) defining the separate compartments (9) are impervious to air and are curved and or angled near their free ends contrary to the direction in which the base is continuously moving.

Die Erfindung betrifft eine Vorrichtung zum Ausrichten und Ablegen von mit mindestens einem Bindemittel versehenen länglichen lignozelluloseund/oder zellulosehaltigen Teilchen wie Holzspänen, Holzfasern oder dergleichen auf einer kontinuierlich bewegten Unterlage zu einem Vlies für die anschließende Herstellung von Platten mit einem solche Teilchen enthaltenden Dosierbunker, einer Einheit zur Überführung der Teilchen zu einer Orientierungseinheit, die oberhalb einer kontinuierlich bewegten Unterlage angeordnet ist, wobei der Abstand zwischen der Orientierungseinheit und der kontinuierlich bewegten Unterlage höher liegt als die Oberseite des zu bildenden Vlieses.The invention relates to a device for aligning and depositing elongated lignocellulose and / or provided with at least one binder cellulose-containing particles such as wood shavings, wood fibers or the like on a continuously moving pad to a fleece for the subsequent production of plates containing such a particle Dosing bunker, a unit for transferring the particles an orientation unit above a continuously moving one Underlay is arranged, the distance between the orientation unit and the continuously moving pad is higher than that Top of the fleece to be formed.

Aus der deutschen Patentschrift 27 34 403 ist eine Vorrichtung bekannt, die zum Ausrichten von mit einem Bindemittel versehenen lignozellulosehaltigen Teilchen (strands), wie Holzspänen, Holzfasern oder dergleichen dient, die, auf eine kontinuierlich bewegte Unterlage aufgebracht, ein Vlies bilden, dessen Teilchen im wesentlichen parallel zueinander ausgerichtet sowie in Bewegungsrichtung oder quer zur Bewegungsrichtung der kontinuierlich bewegten Unterlage verlaufen, bestehend aus mehreren, dünnen Führungsflächen, deren gegenseitige, gleiche Abstände kleiner sind als die Längen der auszurichtenden Teilchen und deren Unterkanten höher liegen als die Oberseite des zu bildenden Vlieses und die derart bewegbar sind, daß jede Führungsfläche gegenüber den beiden benachbarten Führungsflächen in entgegengesetzter Richtung bewegbar ist. Über der oberen Randkante jeder Führungsfläche ragt hierbei in der gleichen Ebene eine Vielzahl voneinander beabstandeter Vorsprünge hinaus, deren Dicke gleich der Dicke der Führungsfläche ist. Diese Vorsprünge sind als regelmäßige Vierecke mit zwei parallelen Kanten und einer oben liegenden, zur Randkante parallelen Oberkante und/oder als Dreiecke mit obenliegender Spitze ausgebildet. Erreicht wird dadurch zwar, daß diejenigen Teilchen, die die Oberkanten zweier oder mehrerer sich bewegender Führungsflächen zunächst überspannen, in einem Bogen verdreht werden und dann zwischen den Führungsflächen parallel zueinander ausgerichtet auf die kontinuierlich bewegte Unterlage fallen, aber es besteht zumindest die Gefahr von Verstopfungen und die Gefahr von Beschädigungen der Teilchen.From the German patent specification 27 34 403 a device is known those for aligning lignocellulose-containing binders Particles (strands), such as wood chips, wood fibers or the like serves, which, applied to a continuously moving base, a fleece form, the particles of which are aligned substantially parallel to one another as well as in the direction of movement or transverse to the direction of movement of the continuously moving pad, consisting of several thin Guide surfaces, the mutual, equal distances are smaller than that Lengths of the particles to be aligned and their lower edges are higher than the top of the fleece to be formed and which are movable in such a way that each guide surface opposite the two adjacent guide surfaces is movable in the opposite direction. Above the top The edge of each guide surface protrudes in the same plane A plurality of spaced apart projections, their thickness is equal to the thickness of the guide surface. These tabs are as regular Quadrilaterals with two parallel edges and one on top, for Border edge parallel top edge and / or as triangles with an overhead Tip trained. What is achieved is that those particles the top edges of two or more moving guide surfaces span first, twisted in an arc and then aligned parallel to each other between the guide surfaces continuously moving pad fall, but there is at least the Risk of blockages and damage to the particles.

Eine anders aufgebaute Einrichtung zum Ausrichten von Holzteilchen (strands) über die Querbreite einer bewegten Unterlage ist aus der deutschen Offenlegungsschrift 2 523 515 bekannt. Zu dieser Einrichtung gehören eine Vororientierungseinheit, die eine Mehrzahl von aufrechten Rippen besitzt, außerdem eine Trommel mit an deren Außenumfang angebrachten Holzstrangorientierungsleitblechen und eine Fangeinrichtung, welche die Holzstränge zwischen einer bogenförmigen Ummantelung und einer Mehrzahl von Räumen, von denen jeder durch die Umfangsfläche der Trommel und einem Paar von Leitblechoberflächen gebildet wird, so lange gefangen hält, bis sie an einer vorbestimmten Stelle freigegeben werden, um parallel zueinander ausgerichtet auf eine bewegte Unterlage fallen zu können, auf der sie sich quer zu deren Bewegungsrichtung ablegen. Der Durchsatz und der Orientierungsgrad der Teilchen sind dabei jedoch nicht zufriedenstellend.A differently designed device for aligning wooden particles (strands) across the width of a moving pad is from the German Laid-open publication 2,523,515. Belong to this facility a pre-orientation unit that has a plurality of upright ribs also has a drum with attached to its outer circumference Wooden strand orientation guide plates and a catching device, which the wooden strands between an arcuate casing and a plurality of spaces, each through the peripheral surface the drum and a pair of baffle surfaces, so long trapped until released at a predetermined location to be aligned parallel to each other on a moving surface to fall on which they lie across their direction of movement. The throughput and the degree of orientation of the particles are however not satisfactory.

Der Erfindung liegt die Aufgabe zugrunde, eine Ausrichtvorrichtung der eingangs genannten Art so auszubilden, daß der Orientierungsgrad der Teilchen bei hoher Durchsatzleistung und ohne Beschädigung der Teilchen im störungsfreien Betrieb verbessert werden kann.The invention has for its object an alignment device trained in such a way that the degree of orientation of Particles with high throughput and without damage to the particles can be improved in trouble-free operation.

Nach der Erfindung ist zur Lösung der Aufgabe vorgesehen, daß die Orientierungseinheit aus mehreren rechtwinkelig zur Bewegungsrichtung der kontinuierlich bewegten Unterlage in einer zumindest im wesentlichen horizontalen Ebene beabstandet angeordneten und entgegen der Bewegungsrichtung kontinuierlich bewegten Unterlage umlaufenden Fächerwalzen besteht, deren die einzelnen Fächer begrenzende, luftundurchlässig ausgebildete Ausrichtflächen zumindest im Bereich ihrer freien Enden entgegen der Bewegungsrichtung der kontinuierlich bewegten Unterlage gekrümmt und/oder abgewinkelt ausgebildet sind. According to the invention the problem is solved provided that the orientation unit consists of several right angles to the direction of movement of the continuously moving pad in one spaced at least substantially horizontally and against the direction of motion continuously moving pad revolving fan rollers, the individual compartments delimiting Air-impermeable alignment surfaces at least in the area their free ends against the direction of movement of the continuously moving pad curved and / or angled are.

Besonders vorteilhafte Ausgestaltungen des Gegenstands der Erfindung sind in den Unteransprüchen angegeben und werden anhand der nachfolgenden Beschreibung von Ausführungsbeispielen unter Bezugnahme auf die Zeichnung erläutert. In der Zeichnung zeigt die einzige

Figur
eine schematische Darstellung einer Ausführungsform der Erfindung mit einer Mehrzahl von Fächerwalzen.
Particularly advantageous refinements of the subject matter of the invention are specified in the subclaims and are explained on the basis of the following description of exemplary embodiments with reference to the drawing. In the drawing shows the only one
figure
is a schematic representation of an embodiment of the invention with a plurality of fan rollers.

Die Figur zeigt einen Dosierbunker 1, der in konventioneller Weise ausgeführt sein kann und neben einem bodenseitigen Transportband und Rückstreifwalzen eine Zuführeinheit 2 aufweist, mittels der die beleimten lignozellulose- und/oder zellulosehaltigen länglichen Teilchen über Pendelklappen 3 einer in einer von einem Gehäuse umschlossenen Orientierungseinheit 4 vorgesehenen Gruppe von Auflösewalzen 5 zugeführt werden.The figure shows a dosing hopper 1, which is carried out in a conventional manner can be and next to a bottom conveyor belt and Stripping rollers has a feed unit 2, by means of which the glued lignocellulosic and / or cellulosic elongated particles over pendulum flaps 3 an orientation unit enclosed in a housing 4 provided group of opening rollers 5 are supplied.

Die Auflösewalzen 5 erstrecken sich über die Breite einer bewegten Unterlage 10, auf der das jeweilige Vlies gebildet wird. Eine erste Gruppe der Auflösewalzen 5 ist im Gegenuhrzeigersinn und eine zweite Gruppe im Uhrzeigersinn angetrieben, so daß das über die Zuführeinheit 2 zugeführte Teilchenmaterial gleichmäßig verteilt wird und entsprechend gleichmäßig auf eine Gruppe von Fächerwalzen 7 trifft, die unterhalb der Gruppe von Auflösewalzen 5 angeordnet und entgegen der Bewegungsrichtung der bewegten Unterlage 10 umlaufend angetrieben sind. Zwischen den Auflösewalzen 5 und den Fächerwalzen 7 sind bezüglich der Vertikalen schräg verlaufende Leitbleche 6 vorgesehen, die sicherstellen, daß die Fächerwalzen 7 gezielt in ihrem oberen Bereich, wo sich die Fächer 9 zu den Auflösewalzen 5 hin öffnen, beschickt werden.The opening rollers 5 extend across the width of a moving base 10, on which the respective fleece is formed. A first group of Opening rollers 5 is counterclockwise and a second group in Driven clockwise so that the supplied via the feed unit 2 Particle material is evenly distributed and accordingly evenly meets a group of fan rollers 7, which below the Group of opening rollers 5 arranged and against the direction of movement the moving pad 10 are driven in rotation. Between the opening rollers 5 and the fan rollers 7 are in relation to the Vertical inclined baffles 6 are provided, which ensure that the fan rollers 7 targeted in their upper area where the fans 9 open towards the opening rollers 5, be loaded.

Die Fächerwalzen 7 besitzen eine Vielzahl von Ausrichtflächen 8, die luftundurchlässig ausgeführt sind und einen solchen gegenseitigen Abstand besitzen, daß nur soviel Teilchenmaterial in einem Fach 9 aufgenommen werden kann, daß eine vollständige Ausrichtung der länglichen Teilchen gewährleistet werden kann.The fan rollers 7 have a plurality of alignment surfaces 8, which are impermeable to air are executed and such a mutual distance have that only so much particulate matter in a compartment 9 can be that a complete alignment of the elongated particles can be guaranteed.

Die Ausrichtflächen 8 sind so gestaltet, daß sie die aufgenommenen und aufgrund der Flachstruktur quer zur Bewegungsrichtung der Unterlage 10 ausgerichteten länglichen Teilchen erst wieder dann aus den Fächern 9 abgeben, wenn der Fallweg der Teilchen zwischen Fächerwalze 7 und bewegter Unterlage 10 bzw. dem sich auf dieser bewegten Unterlage 10 bildenden Vlies minimiert ist.The alignment surfaces 8 are designed so that they are the recorded and due to the flat structure transverse to the direction of movement of the base 10 aligned elongated particles only then again from the compartments 9 give up when the fall of the particles between fan roller 7 and moving Base 10 or the base 10 formed on this moving base Fleece is minimized.

Erreicht wird dies durch die spezielle Formgestaltung der Ausrichtflächen 8, welche bezüglich der länglichen Teilchen einen Rückhalteeffekt bewirkt und erst dann zuläßt, daß die länglichen, ausgerichteten Teilchen das jeweilige Fach 9 verlassen bzw. aus diesem Fach rutschen, wenn das betreffende Fach 9 sich in einer unteren bzw. vliesnahen Position befindet. Dazu sind die Ausrichtflächen 8 entgegen der Umlaufrichtung der Fächerwalze 7 zumindest im Bereich ihrer freien Enden gekrümmt und/oder abgewinkelt ausgebildet. Je nach den praktischen Gegebenheiten, können die Ausrichtflächen kontinuierlich gekrümmt, mit zum freien Ende hin sich verringernden Krümmungsradius gekrümmt oder auch nur im Bereich der freien Enden gekrümmt ausgebildet sein. Anstelle einer kontinuierlichen Krümmung kann auch vorgesehen sein, die Ausrichtflächen 8 insbesondere mehrfach zu knicken, so daß mehrere ebene, über Knickstellen miteinander verbundene Teilflächen vorliegen, die eine gekrümmte Struktur polygonartig annähern.This is achieved through the special design of the alignment surfaces 8, which causes a retention effect with respect to the elongated particles and only then does the elongated, aligned particles allow the particular Leave compartment 9 or slip out of this compartment if the relevant one Tray 9 is in a lower or fleece-like position. For this purpose, the alignment surfaces 8 are opposite to the direction of rotation of the fan roller 7 curved and / or at least in the region of their free ends angled. Depending on the practical circumstances, can the alignment surfaces are continuously curved, with towards the free end decreasing radius of curvature curved or only in the area the free ends can be curved. Instead of a continuous one Curvature can also be provided, the alignment surfaces 8 especially to fold several times, so that several levels, over kinks interconnected partial surfaces are present, which is a curved Approach the structure like a polygon.

Die von einem Gehäuse umschlossene Orientierungseinheit 4 ist bevorzugt bezüglich der bewegten Unterlage 10 höhenverstellbar ausgebildet, wie dies durch Doppelpfeile angedeutet ist. Die Achsen der untereinander identisch ausgebildeten Fächerwalzen 7 liegen bevorzugt in einer Ebene, die mit der bewegten Unterlage 10 einen dem Anstiegswinkel des auf der Unterlage 10 gebildeten Vlieses zumindest im wesentlichen entsprechenden Verlauf besitzt.The orientation unit 4 enclosed by a housing is preferred is adjustable in height with respect to the moving base 10, as indicated by double arrows. The axes of each other Identical fan rollers 7 preferably lie in one plane, the one with the moving pad 10 the angle of rise of the on the Base 10 formed nonwoven at least substantially corresponding History.
