Description

Die Erfindung betrifft eine Vorrichtung zum Streuen von für die Herstellung von Preßplatten od.dgl. bestimmten Matten aus beleimtem Faser-oder Spanmaterial, welche eine Beleimungsmaschine für das Faser- oder Spanmaterial, an den Auslaß der Beleimungsmaschine anschließende Transporteinrichtungen für das beleimte schüttfähige Material, wenigstens einen Dosierbunker für das beleimte Material, wenigstens einen Streuraum, dessen Boden ein zu einer Plattenpresse laufendes Förderband bildet, und wenigstens eine in den Streuraum mündende Luftdüse, die von einem Ventilator mit Druckluft versorgt wird, aufweist.The invention relates to a device for spreading or the like for the production of press plates. certain mats made of glued fiber or chip material, which have a gluing machine for the fiber or chip material, transport devices for the glued pourable material connected to the outlet of the gluing machine, at least one dosing hopper for the glued material, at least one spreading space, the bottom of which forms a plate press forms a running conveyor belt, and has at least one air nozzle opening into the spreading space and supplied with compressed air by a fan.

Vorrichtungen dieser Art bezeichnet man auch als Windstreumaschinen. Mittels derartiger Windstreumaschinen wird zuvor in einer Beleimmaschine wie einem speziellen Mischer beleimtes schüttfähiges Faser- oder Spanmaterial zu einer mattenförmigen Bahn bestimmter Dicke und möglichst gleichmäßiger Konsistenz aufgeschüttet, die beim Abtransport von der Windstreumaschine allmählich mittels Druckwalzen verdichtet und danach in Platten vorbestimmter Größe geschnitten wird, welche in einer Heißpresse zu dem Endprodukt, nämlich den Faser- oder Spanplatten, gepreßt wird.Devices of this type are also known as wind scattering machines. By means of such wind scattering machines, glued pourable fiber or chip material is previously piled up in a gluing machine such as a special mixer to form a mat-shaped web of a certain thickness and as uniform a consistency as possible, which is gradually compacted by means of pressure rollers during removal from the wind scattering machine and then cut into plates of a predetermined size, which is pressed in a hot press to the end product, namely the fiber or chipboard.

Es hat sich gezeigt, daß bei den bekannten Windstreumaschinen beim Streuvorgang aufgrund der zugeführten frischluft und Umluft das Streugut verhältnismäßig stark austrocknet, was zu Qualitätsschwankungen und auch dazu führt, daß ein verhältnismäßig großer Leimanteil benötigt wird, weil durch die starke Austrocknung des Streugutes die Aktivierbarkeit des Leimes nachläßt.It has been shown that in the known wind-spreading machines, the spreading material dries out comparatively strongly during the spreading process due to the fresh air and circulating air supplied, which leads to quality fluctuations and also to the fact that a relatively large proportion of glue is required because the activatability of the spreading material is caused by the strong drying out of the spreading material Glue subsides.

Der Erfindung liegt die Aufgabe zugrunde, beim Streuen von Matten od.dgl. aus beleimtem Faser- und Spanmaterial ein übermäßiges und ungleichförmiges Austrocknen des schüttfähigen Materials zu vermeiden.The invention has for its object, or the like when spreading mats. to avoid excessive and non-uniform drying of the pourable material from glued fiber and chip material.

Diese Aufgabe wird mit einer Vorrichtung der eingangs genannten Gattung gelöst, welche die kennzeichnenden Merkmale des Patentanspruches 1 aufweist. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved with a device of the type mentioned at the outset, which has the characterizing features of patent claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.

Gemäß der vorliegenden Erfindung kann die von den Ventilatoren angesaugte Luft aus dem Transportsystem zwischen dem Auslaß bzw. Ausfall der Beleimmaschine und dem Dosierbunker entnommen werden, wobei es auch möglich ist, zusätzlich zu der aus dem Transportsystem angesaugten feuchten Luft weitere feuchte Luft aus dem Dosierbunker zu entnehmen. Auch ist es möglich, nur aus dem Dosierbunker mittels der Ventilatoren feuchte Luft anzusaugen und damit zu entnehmen.According to the present invention, the air sucked in by the fans can be removed from the transport system between the outlet or failure of the gluing machine and the dosing bunker, it being also possible to add further moist air from the dosing bunker in addition to the moist air sucked in by the transport system remove. It is also possible to draw in and remove humid air from the dosing hopper using the fans.

Dabei ist es vorteilhaft, die Menge der angesaugten feuchten Luft durch eine Luftmengen-Regelung zu steuern. Zusätzlich kann Frischluft in geregelter Menge zugegeben werden. Auf diese Weise kann die Feuchte des Streugutes gezielt beeinflußt werden.It is advantageous to control the amount of humid air sucked in by means of an air volume control. Fresh air can also be added in a controlled amount. In this way, the moisture content of the grit can be influenced in a targeted manner.

Durch die Erfindung läßt sich in einfacher Weise gezielt die Qualität von Faser- und Spanplatten verbessern, weil der Feuchtigkeitsgehalt des zu einer Matte oder einem Vlies geschütteten Materials gleichmäßig gesteuert werden kann. Darüber hinaus kann man Leim einsparen, weil durch die richtige Feuchtigkeitsführung des schüttfähigen Materials der diesem zugegebene Leim optimal genutzt werden kann. Schließlich wird auch eine übermäßige Feuchtigkeitsbildung vermieden, so daß die gesamte Vorrichtung ausreichend trocken gehalten werden kann, um unerwünschte Materialablagerungen und Materialanbackungen zu verhindern.By means of the invention, the quality of fiber and chipboard can be specifically improved in a simple manner, because the moisture content of the material poured into a mat or a fleece can be controlled uniformly. In addition, glue can be saved because the correct moisture management of the pourable material allows the glue added to it to be used optimally. Finally, excessive moisture formation is avoided so that the entire device can be kept sufficiently dry to prevent undesirable material deposits and material caking.

Mit der erfindungsgemäßen Vorrichtung ist es möglich, durch ein spezielles Feuchtluft-Streusystem eine konstante Qualität des Streugutes zu gewährleisten, die auch zu einer gleichmäßigen Qualität des schließlich erzeugten Endproduktes führt.With the device according to the invention, it is possible to ensure a constant quality of the spreading material by means of a special moist air spreading system, which also leads to a uniform quality of the end product ultimately produced.

Die in Fig. 1 gezeigte Windstreumaschine (1) weist zwei Dosierbunker (2 und 3) auf, unter denen sich jeweils ein Streuraum (4 bzw. 5) befindet. Unter den beiden Streuräumen (4 und 5) befindet sich ein endloses Transportband (6), das das in den beiden Streuräumen (4 und 5) aufgeschüttete beleimte Spangut in Richtung des Pfeiles (7) zu einer nur schematisch angedeuteten Bearbeitungsstation (8) führt, wo das mattenförmig gestreute Spanmaterial verdichtet und schließlich zu Spanplatten gepreßt wird.The wind scattering machine (1) shown in Fig. 1 has two dosing bunkers (2 and 3), under each of which there is a spreading space (4 and 5). Under the two spreading spaces (4 and 5) there is an endless conveyor belt (6) which leads the glued chip in the two spreading spaces (4 and 5) in the direction of arrow (7) to a processing station (8), which is only indicated schematically, where the mat-shaped chip material is compacted and finally pressed to chipboard.

Das beleimte Span- und Fasermaterial wird von einem geschlossenen Transporteur (9) herangeführt und durch einen Doppeltrichter (10) auf zwei gegenläufig angetriebene Schneckenförderer (11 und 12) aufgegeben, welche das beleimte Span- oder Fasermaterial in etwa gleichförmiger Aufteilung den beiden Dosierbunkern (2 und 3) zuführt.The glued chip and fiber material is brought in by a closed conveyor (9) and fed through a double hopper (10) to two counter-rotating screw conveyors (11 and 12) which distribute the glued chip or fiber material in an approximately uniform distribution to the two dosing bunkers (2 and 3) feeds.

In jedem Dosierbunker befinden sich vier jeweils um eine horizontale Achse (13) drehbare Rechen (14), auf die das beleimte Span- oder Fasermaterial von den Schneckenförderern (11 und 12) aufgeschüttet wird. Diese Rechen (14) lockern das aufgeschüttete Material auf, das nach unten auf ein im Dosierbunker befindliches horizontales Förderband (15 bzw. 16) fällt.In each dosing hopper there are four rakes (14), each rotatable about a horizontal axis (13), onto which the glued chip or fiber material is poured by the screw conveyors (11 and 12). These rakes (14) loosen up the heaped-up material that falls down onto a horizontal conveyor belt (15 or 16) located in the dosing hopper.

Das im Dosierbunker (2) angeordnete Förderband (15) wird so angetrieben, daß sein Obertrum - in Fig. 1 gesehen - nach rechts läuft, während das im Dosierbunker (3) angeordnete Förderband (16) in entgegengesetzter Richtung angetrieben wird.The conveyor belt (15) arranged in the dosing hopper (2) is driven in such a way that its upper run - seen in FIG. 1 - runs to the right, while the conveyor belt (16) arranged in the dosing hopper (3) is driven in the opposite direction.

Unter dem Abgabeende jedes Förderbandes (15 und 16) befinden sich über die Breite des betreffenden Förderbandes verlaufende Pendelklappen (17), die in den darunter befindlichen Streuraum (4 bzw. 5) führen. Oberhalb der Pendelklappen (17) ist in jedem der Dosierbunker (2 und 3) eine Dosierwalze (18) um eine horizontale Achse (19) drehbar gelagert, die gewährleistet, daß die Förderbänder (15 und 16) das aufgelockerte beleimte Span- oder Fasermaterial in gleichförmiger Mengenverteilung in die Pendelklappen (17) abgeben.Under the delivery end of each conveyor belt (15 and 16) there are pendulum flaps (17) running across the width of the conveyor belt in question, which lead into the spreading space (4 and 5) below. Above the swing flaps (17) in each of the metering bunkers (2 and 3) a metering roller (18) is rotatably mounted about a horizontal axis (19), which ensures that the conveyor belts (15 and 16) the loosened glued chip or fiber material in Dispense uniform quantity distribution into the pendulum flaps (17).

Zwischen den Dosierbunkern (2 und 3) sind zwei Blaslufteinrichtungen (20 und 21) angeordnet. Jede Blaslufteinrichtung (20 bzw. 21) hat ein in Seitenansicht winkelförmig ausgebildetes Gehäuse (22) zum Heranführen von Luft. Am oberen Ende dieses Gehäuses (22) befindet sich eine Öffnung (23) mit Regelklappe (24), durch welche Frischluft zugeführt werden kann. Am Ende des etwa horizontal verlaufenden Schenkels (25) ist eine weitere Öffnung (26) vorgesehen, die in den unter dieser befindlichen Dosierbunker (2 bzw. 3) führt und durch die Luft aus dem betreffenden Dosierbunker entnommen werden kann. Eine Regelklappe (27) im horizontalen Schenkel (25) des Gehäuses (22) dient zur Steuerung der Luftzufuhr aus dem betreffenden Dosierbunker.Two blast air devices (20 and 21) are arranged between the dosing bunkers (2 and 3). Each blowing air device (20 or 21) has a housing (22), which is angular in side view, for introducing air. At the upper end of this housing (22) there is an opening (23) with a control flap (24) through which fresh air can be supplied. At the end of the approximately horizontally extending leg (25) there is a further opening (26) which leads into the metering bunker (2 or 3) located below it and through which air can be removed from the relevant metering bunker. A control flap (27) in the horizontal leg (25) of the housing (22) serves to control the air supply from the dosing hopper in question.

Im unteren Teil des Gehäuses (22) sind jeweils zwei Ventilatoren (28) angeordnet, welche Luft ansaugen und durch Düsen (29) in den jeweiligen Streuraum (4 bzw. 5) blasen. Die ausgeblasene Luft trifft im Streuraum etwa rechtwinklig auf das durch die Pendelklappe (17) eingeschüttete beleimte Faser- oder Spanmaterial, so daß dasselbe auf das Transportband (6) locker aufgestreut wird.Two fans (28) are arranged in the lower part of the housing (22), which suck in air and blow through nozzles (29) into the respective spreading space (4 or 5). The blown-out air hits the glued fiber or chip material poured through the pendulum flap (17) approximately at right angles in the spreading space, so that the same is loosely scattered onto the conveyor belt (6).

In den beiden Streuräumen (4 und 5) sind mehrere Hängesiebe (30) angebracht, die als Flugspanfänger arbeiten. Dies bedeutet, daß leichte Flächenspäne abgehalten werden, auf die feine Oberfläche der Spanplatte zu gelangen. Die Siebe (30) sind mit Vibratormotoren versehen, um sie sauber zu halten.In the two spreading rooms (4 and 5) there are several hanging sieves (30) that work as fly chip catchers. This means that light chips are prevented from getting onto the fine surface of the chipboard. The screens (30) are provided with vibrator motors to keep them clean.

Da die in den Dosierbunkern (2 und 3) befindliche Luft verhältnismäßig feucht ist, kann man auch mit verhältnismäßig feuchter Blasluft arbeiten, so daß ein übermäßiges Austrocknen des Faser- oder Spanmaterials beim Streuvorgang vermieden wird. Der Anteil der von den Ventilatoren (28) angesaugten Frischluft kann gegenüber dem Anteil der aus den Dosierbunkern angesaugten feuchten Luft verhältnismäßig gering gehalten werden.Since the air in the dosing bunkers (2 and 3) is relatively humid, one can also work with relatively humid blown air, so that excessive drying of the fiber or chip material during Scattering process is avoided. The proportion of fresh air drawn in by the fans (28) can be kept relatively low compared to the proportion of moist air drawn in from the dosing bunkers.

An das Ende jedes Streuraumes (4 bzw. 5) ist eine Abluftleitung (31 bzw. 32) angeschlossen, die ineinander münden und zu einem nicht dargestellten Filter führen, mit dessen Hilfe die in der Abluft befindlichen Reste der Verdunstungen des Leimanteiles und sonstige Bestandteile des verarbeiteten Span- oder Fasermaterials entfernt werden.At the end of each spreading space (4 or 5) an exhaust air line (31 or 32) is connected, which open into each other and lead to a filter, not shown, with the help of the residues in the exhaust air of the evaporation of the glue component and other components of the processed chip or fiber material can be removed.

Während bei der in Fig. 1 gezeigten Ausführungsform einer Windstreumaschine feuchte Blasluft von den Ventilatoren (28) ausschließlich aus den Dosierbunkern (2 und 3) angesaugt wird, ist bei der Ausführungsform gemäß Fig. 2 vorgesehen, feuchte Blasluft auch aus dem zu den Dosierbunkern führenden Transportsystem anzusaugen.While in the embodiment of a wind scattering machine shown in FIG. 1, moist blown air is sucked in by the fans (28) exclusively from the metering bunkers (2 and 3), in the embodiment according to FIG. 2, moist blown air is also provided from that leading to the metering bunkers To suck in the transport system.

Das in einer Beleimmaschine (33) beleimte Span- oder Fasermaterial wird durch gekapselte Fördereinrichtungen (34, 35, 36) und einen zwischengeschalteten Doppeltrichter (10) in die beiden Dosierbunker (2 und 3) der Windstreumaschine geleitet. Die Windstreumaschine ist dabei im wesentlichen so ausgebildet, wie in Verbindung mit Fig. 1 erläutert.The chip or fiber material glued in a gluing machine (33) is passed through encapsulated conveyors (34, 35, 36) and an interposed double funnel (10) into the two dosing bunkers (2 and 3) of the wind scattering machine. The wind scattering machine is essentially designed as explained in connection with FIG. 1.

An den Saugstutzen (37) jedes der in die Streuräume der Windstreumaschine arbeitenden Ventilatoren (28) ist eine Saugleitung (38) angeschlossen, die mehrere Abzweigungen (39) aufweist, welche in den betreffenden Dosierbunker (2 bzw. 3), in der Gehäuse der betreffenden Fördereinrichtung (35 bzw. 36) und in das Gehäuse der Fördereinrichtung (34) münden. Somit kann feuchte Luft von verschiedenen Stellen des gesamten Systems angesaugt werden.A suction line (38) is connected to the suction nozzle (37) of each of the fans (28) working in the spreading spaces of the wind scattering machine and has a plurality of branches (39) which flow into the relevant dosing hopper (2 or 3) in the housing of the relevant conveyor (35 or 36) and open into the housing of the conveyor (34). This means that moist air can be drawn in from various points in the entire system.

Die für die Steuerung der angesaugten Luft verwendeten Regelklappen sind in Fig. 2 nicht dargestellt.The control flaps used to control the intake air are not shown in FIG. 2.

Die in Fig. 3 gezeigte Ausführungsform unterscheidet sich von der Ausführungsform gemäß Fig. 2 lediglich dadurch, daß die Saugleitung (38) ausschließlich an die Fördereinrichtungen (34, 35, 36) angeschlossen sind und somit nur aus dem Transportsystem feuchte Luft angesaugt wird.The embodiment shown in FIG. 3 differs from the embodiment according to FIG. 2 only in that the suction line (38) is connected exclusively to the conveying devices (34, 35, 36) and thus only moist air is sucked in from the transport system.

Bei allen drei Ausführungsformen wird die Menge der angesaugten feuchten Luft durch eine Luftmengen-Regelung gesteuert. Außerdem ist die Zugabe von Frischluft in geregelter Menge möglich. Auf diese Weise läßt sich die Feuchtigkeit des Streugutes bzw. des gestreuten beleimten Faser- oder Spanmaterials beeinflussen und einstellen.In all three embodiments, the amount of moist air sucked in is controlled by an air amount control. It is also possible to add fresh air in a controlled amount. In this way, the moisture of the spreading material or the scattered glued fiber or chip material can be influenced and adjusted.

Die Vorteile der erfindungsgemäßen Streuvorrichtung liegen in einer Verbesserung der Qualität des Streugutes, der Möglichkeit von Einsparungen von Leim und der Möglichkeit, das gesamte System trocken zu halten.The advantages of the spreading device according to the invention lie in an improvement in the quality of the spreading material, the possibility of saving glue and the possibility of keeping the entire system dry.
