Description

Die Erfindung betrifft eine Vorrichtung zum Abführen von seitlich aus einer kontinuierlichen Presse zur Herstellung von Holzwerkstoffplatten austretenden Holzspänen oder anderen Holzpartikeln, wobei die Presse jeweils ein unter Pressspaltbildung umlaufendes Oberband und Unterband aufweist, die mit Hilfe zumindest teilweise beheizbarer Druckplatten gegen einen Holzfaserwerkstoff pressbar sind.The invention relates to a device for removing wood chips or other wood particles emerging laterally from a continuous press for the production of wood-based panels, the press each having an upper band and a lower band forming a press gap, which can be pressed against a wood fiber material with the aid of at least partially heatable pressure plates.

Die Erfindung betrifft ferner ein Verfahren zum Abführen von seitlich aus einer kontinuierlichen Presse zur Herstellung von Holzwerkstoffplatten austretenden Holzspänen oder anderen Holzpartikeln, wobei die Presse jeweils ein unter Pressspaltbildung umlaufendes Oberband und Unterband aufweist, die mit Hilfe zumindest teilweise beheizbarer Druckplatten gegen einen Holzfaserwerkstoff gepresst werden.The invention further relates to a method for removing wood chips or other wood particles emerging laterally from a continuous press for the production of wood-based panels, the press each having an upper band and a lower band rotating under the formation of a press gap, which are pressed against a wood fiber material with the aid of at least partially heatable pressure plates.

Bei der Herstellung von Holzwerkstoffplatten wird heutzutage in der Regel eine sogenannte Doppelbandpresse verwendet. Zwei umlaufende Stahlbänder laufen über den Pressabschnitt, in dem der Holzfaserwerkstoff kontinuierlich zu einer Holzwerkstoffplatte verpresst wird, unter Druck gegeneinander. Sie werden dabei in der Regel über Rollkörper geführt, die sich wiederum auf zumindest teilweise beheizbaren Druckplatten abstützen, von denen entweder die oberen oder die unteren oder beide über Hydraulikzylinder, die sich am Pressenrahmen abstützen, beaufschlagbar sind.Nowadays, a so-called double belt press is generally used in the production of wood-based panels. Two circumferential steel strips run against each other under pressure over the press section, in which the wood fiber material is continuously pressed into a wood material board. They are generally guided over rolling elements, which in turn are supported on at least partially heatable pressure plates, of which either the upper or the lower or both can be acted upon via hydraulic cylinders which are supported on the press frame.

Durch die hohen Temperaturen und Drücke, insbesondere am Ende der Presse, kommt es zum Verdampfen von der in den Holzfasern eingeschlossenen Feuchtigkeit. Der entstehende Gasdruck bedingt, dass Holzspäne oder anderen Holzpartikel seitlich aus dem Pressspalt herausgeschleudert werden.Due to the high temperatures and pressures, especially at the end of the press, the moisture trapped in the wood fibers evaporates. The resulting gas pressure means that Wood chips or other wood particles are thrown out of the side of the press nip.

Das verursacht nicht nur einen großen Reinigungsaufwand, sondern ist zudem gefährlich, denn die Späne und anderen Holzpartikel können sich an den heißen Versorgungsleitungen für die beheizbaren Druckplatten entzünden.This not only causes a lot of cleaning, but is also dangerous because the chips and other wood particles can ignite on the hot supply lines for the heatable pressure plates.

Aus der DE 101 00 895 A1 ist es beispielsweise bekannt, die austretenden Späne zu befeuchten und direkt abzusaugen. Dies verursacht mit der Installation der Befeuchtungsanlage einen großen Aufwand. Außerdem bewirkt die Absaugung, dass auch Späne und Partikel aus dem Randbereich des Holzfaserwerkstoffs herausgesaugt werden und somit die Ränder der fertigen Holzfaserplatte eine unerwünschte andere Dichte aufweisen als die Mitte. Diese Ränder müssen oft an den fertigen Holzwerkstoffplatten abgeschnitten werden.From the DE 101 00 895 A1 it is known, for example, to moisten the emerging chips and to suction them off directly. This causes a great deal of effort when installing the humidification system. In addition, the suction means that chips and particles are also sucked out of the edge area of the wood fiber material and thus the edges of the finished wood fiber board have an undesirably different density than the center. These edges often have to be cut off on the finished wood-based panels.

DE10228936 A1 offenbart den Oberbegriff der Ansprüche 1 und 9. DE10228936 A1 discloses the preamble of claims 1 and 9.

Es ist deshalb die Aufgabe der Erfindung, eine Vorrichtung und ein Verfahren zum Abführen von seitlich aus einer kontinuierlichen Presse zur Herstellung von Holzwerkstoffplatten austretenden Holzspänen oder anderen Holzpartikeln zu schaffen, bei denen die beschriebenen Nachteile vermieden werden.It is therefore the object of the invention to provide a device and a method for removing wood chips or other wood particles emerging laterally from a continuous press for the production of wood-based panels, in which the disadvantages described are avoided.

Hinsichtlich der Vorrichtung wird die Aufgabe durch die Merkmale des Anspruchs 1 und insbesondere dadurch gelöst, dass seitlich des Pressspaltes zumindest in einem Endabschnitt der Presse eine Auffangtrichteranordnung für die Holzspäne oder anderen Holzpartikel angeordnet ist, die diese zu einer mechanischen Transportvorrichtung weiterleitet.With regard to the device, the object is achieved by the features of claim 1 and in particular in that a collecting funnel arrangement for the wood chips or other wood particles, which forwards them to a mechanical transport device, is arranged at the side of the press nip at least in one end section of the press.

Man erhält dadurch die Möglichkeit, die aus dem Pressspalt austretenden Späne unmittelbar aufzufangen, ohne dass sie das Umfeld der Presse verschmutzen oder sich an den Leitungen der heißen Wärmeträger für die Heizplatten entzünden können. Dabei werden die Späne nicht unmittelbar in eine Saugleitung angesaugt, sondern fallen aufgrund ihrer Schwerkraft und in ihrer Bewegungsfreiheit durch die Seitenwände der Auffangtrichteranordnung begrenzt auf eine Transportvorrichtung, die die Späne abtransportiert.This gives you the option of directly collecting the chips emerging from the press nip without contaminating the surroundings of the press or on the lines of the hot heat transfer media for the Can ignite hot plates. The chips are not sucked directly into a suction line, but fall due to their gravity and their freedom of movement through the side walls of the collecting funnel arrangement limited to a transport device that transports the chips away.

Es ist vorteilhaft, wenn die Transportvorrichtung durch wenigstens eine Transportschnecke gebildet ist.It is advantageous if the transport device is formed by at least one transport screw.

Dadurch kann die Auffangtrichteranordnung eine längere Form in Durchlaufrichtung der Presse aufweisen. Die durch die Auffangtrichteranordnung abgeführten Späne fallen von oben in die oben geöffnete Transportschnecke und werden, vorzugsweise ebenfalls parallel zur Durchlaufrichtung der Presse, abtransportiert.As a result, the collecting funnel arrangement can have a longer shape in the direction of passage of the press. The chips discharged through the collecting funnel arrangement fall from above into the transport screw which is open at the top and are removed, preferably likewise parallel to the direction of travel of the press.

Bevorzugt sind in Transportrichtung mehrere Transportschnecken übereinander und teilweise überlappend angeordnet.A plurality of transport screws are preferably arranged one above the other and partially overlapping in the transport direction.

Durch die Überlappung kann eine obere Transportschnecke die transportierten Späne an eine untere Transportschnecke übergeben. Mit dieser Anordnung ist es möglich, kürzere Transportschnecken zu verwenden, so dass die Antriebe kleiner dimensioniert werden können, als wenn nur eine einzige Transportschnecke über die gesamte gewünschte Transportlänge eingesetzt wird.Due to the overlap, an upper screw conveyor can transfer the transported chips to a lower screw conveyor. With this arrangement it is possible to use shorter transport screws, so that the drives can be dimensioned smaller than if only a single transport screw is used over the entire desired transport length.

Es ist von Vorteil, wenn die Transportvorrichtung in einer Absaugeinrichtung endet.It is advantageous if the transport device ends in a suction device.

Die Absaugeinrichtung hat dabei keinen absaugenden Einfluss mehr auf den Pressspalt zwischen Ober- und Unterband, so dass der Holzfaserwerkstoff an den Rändern nicht abgetragen wird.The suction device no longer has a suction effect on the press gap between the upper and lower belt, so that the wood fiber material is not removed at the edges.

Bevorzugt besteht die Auffangtrichteranordnung aus mehreren Trichtern in der Nähe des Pressspaltes, deren Länge so dimensioniert ist, dass sie einzeln oder in einer Gruppe genau zwischen Rahmen der kontinuierlichen Presse passen.The collecting hopper arrangement preferably consists of several hoppers in the vicinity of the press nip, the length of which is dimensioned such that they fit individually or in a group exactly between the frames of the continuous press.

Die hintereinandergeschalteten Rahmen der kontinuierlichen Presse stehen dem Umstand entsprechend seitlich über die Pressbänder hinaus, die innerhalb des Rahmens umlaufen. Demzufolge ist es vorteilhaft, wenn die einzelnen Trichter der Trichteranordnung genau zwischen die Rahmen passen, weil sie dadurch dicht an den Pressspalt gebracht sind und die ganze nach außen offene Pressspaltlänge abdecken können. Unter dem Begriff "Nähe" ist hier ein Abstand von 5 bis 200 mm zu verstehen.The frames of the continuous press, which are connected in series, stand laterally beyond the press belts that run inside the frame. It is therefore advantageous if the individual funnels of the funnel arrangement fit exactly between the frames, because they are brought close to the press nip and can cover the entire press nip length that is open to the outside. The term "proximity" here means a distance of 5 to 200 mm.

Vorzugsweise bilden die Trichteranordnung und die Transporteinrichtungen eine vorgefertigte Baueinheit.The funnel arrangement and the transport devices preferably form a prefabricated structural unit.

Die Montage und Demontage wird dadurch vereinfacht. Mit einem Hallenkran ist die gesamte Baueinheit bewegbar und für Wartungszwecke austauschbar.This simplifies assembly and disassembly. The entire assembly can be moved and replaced for maintenance purposes with an indoor crane.

Um sowohl die Presse als auch die Baueinheit noch einfacher warten zu können, ist die Baueinheit mit Vorteil quer zur Durchlaufrichtung der kontinuierlichen Presse verfahrbar.In order to be able to maintain both the press and the assembly even more easily, the assembly can advantageously be moved transversely to the direction of travel of the continuous press.

Dadurch wird ein Freiraum geschaffen, in dem die Wartungsarbeiten bequemer durchgeführt werden können. Die Baueinheit aus einer Trichteranordnung und einer Transporteinrichtung kann beispielsweise auf Schienen im Hallenboden verfahrbar sein. Sie kann beispielsweise in einer ersten Endposition mit der Trichteröffnung in der Nähe des Pressspaltes stehen und in einer zweiten Endposition von der kontinuierlichen Presse so weit weggerückt sein, dass Wartungsarbeiten an der gesamten Anlage leichter durchzuführen sind.This creates a space in which the maintenance work can be carried out more conveniently. The assembly comprising a funnel arrangement and a transport device can, for example, on rails in the hall floor be movable. For example, it can be in a first end position with the hopper opening near the press nip and in a second end position it can be so far away from the continuous press that maintenance work on the entire system can be carried out more easily.

Vorzugsweise sind seitlich an der Längsseite der kontinuierlichen Presse verlaufende Versorgungsrohre entweder unterhalb des Hallenbodens oder oberhalb des Pressspaltes angeordnet.Preferably, supply pipes running laterally on the long side of the continuous press are arranged either below the hall floor or above the press nip.

Die Installation der Auffangtrichteranordnung und der Transporteinrichtung wird deutlich vereinfacht. Und insbesondere können sie als Baueinheit ungehindert verfahren werden.The installation of the collecting funnel arrangement and the transport device is significantly simplified. And in particular, they can be moved freely as a structural unit.

Hinsichtlich des Verfahrensanspruchs wird die erfindungsgemäße Aufgabe mit der Merkmalen des Anspruchs 9 gelöst und insbesondere dadurch, dass seitlich des Pressspaltes zumindest in einem Endabschnitt der Presse eine Auffangtrichteranordnung für die Holzspäne oder anderen Holzpartikel angeordnet wird, mit dieser Auffangtrichteranordnung die Holzspäne oder anderen Holzpartikel aufgefangen werden, zu einer mechanischen Transportvorrichtung weiterleitet werden und mit der Transportvorrichtung befördert werden.With regard to the method claim, the object according to the invention is achieved with the features of claim 9 and in particular in that a collecting funnel arrangement for the wood chips or other wood particles is arranged at the side of the press nip at least in one end section of the press, with which wood funnel or other wood particles are collected with this collecting funnel arrangement. be forwarded to a mechanical transport device and transported by the transport device.

Die abhängigen Verfahrensansprüche entsprechen in ihren Vorzügen der Beschreibung der Vorrichtung.The advantages of the dependent method claims correspond to the description of the device.

Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen näher erläutert. In dieser zeigt

  • Figur 1 eine Querschnitts-Darstellung einer kontinuierlichen Doppelbandpresse mit einer erfindungsgemäßen Vorrichtung,
  • Figur 2 eine Seitenansicht eines Endes einer kontinuierlichen Doppelbandpresse mit der erfindungsgemäßen Vorrichtung
The invention is explained in more detail below using an exemplary embodiment with reference to the drawings. In this shows
  • Figure 1 2 shows a cross-sectional illustration of a continuous double belt press with a device according to the invention,
  • Figure 2 a side view of one end of a continuous double belt press with the device according to the invention

Figur 1 und 2 zeigen die gleiche Anlage mit einer kontinuierlichen Doppelbandpresse 2 und der erfindungsgemäßen Vorrichtung 1 aus zwei unterschiedlichen Blickrichtungen, als Querschnitt und als Seitenansicht. Figure 1 and 2 show the same system with a continuous double belt press 2 and the device 1 according to the invention from two different viewing directions, as a cross section and as a side view.

In Fig. 2 erkennt man das Ende einer Kontinuierlichen Doppelbandpresse 2 mit einem umlaufenden Oberband 3 und einem umlaufenden Unterband 4. Oberband 3 und Unterband 4 bilden einen Pressspalt 5 in dem ein Holzwerkstoff 6, bestehend zumindest zu einem großen Teil aus Holzspänen oder anderen Holzpartikeln verpresst wird.In Fig. 2 one recognizes the end of a continuous double belt press 2 with a rotating upper belt 3 and a rotating lower belt 4. Upper belt 3 and lower belt 4 form a press nip 5 in which a wood material 6, consisting at least to a large extent of wood chips or other wood particles, is pressed.

Der Pressvorgang erfolgt über obere Druckplatten 7 und untere Druckplatten 8, von denen zumindest eine durch hydraulische Andrückzylinder 9 zum Beispiel unter Zwischenschaltung von nicht dargestellten Rollkörpern gegen wenigstens ein umlaufendes Band 3, 4 gepresst werden und damit den Pressspalt 5 schließen und auf den Holzwerkstoff 6 wirken. Die Andrückzylinder 9 sind beispielsweise an einzelnen Rahmen 13 befestigt und werden beispielsweise aus einer Hydraulikstation 10 mit Drucköl versorgt. Dabei können ihre Drücke über die Breite und Länge der kontinuierlichen Presse von Zylinder zu Zylinder variieren und separat einstellbar sein.The pressing process takes place via upper pressure plates 7 and lower pressure plates 8, of which at least one is pressed against at least one circumferential belt 3, 4 by hydraulic pressure cylinders 9, for example with the interposition of rolling elements, not shown, and thus closes the press gap 5 and acts on the wood material 6 , The pressure cylinders 9 are fastened to individual frames 13, for example, and are supplied with pressure oil from a hydraulic station 10, for example. Their pressures can vary from cylinder to cylinder across the width and length of the continuous press and can be set separately.

Das untere Trum des Oberbandes 3 und das obere Trum des Unterbandes 4 bilden innerhalb der Rahmen 13 den Pressspalt 5 und werden über Leitwalzen 14 umgelenkt schließlich oberhalb bzw. unterhalb der Rahmen 13 zurückgeführt.The lower run of the upper belt 3 and the upper run of the lower belt 4 form the press nip 5 within the frame 13 and are guided over guide rollers 14 deflected finally returned above or below the frame 13.

Die beheizbaren Druckplatten 6, 7 werden in der Regel über längs der kontinuierlichen Presse verlaufende Zuleitungen 11 und Stichleitungen 12 mit einem Heizmedium, beispielsweise Heizöl, versorgt, das durch in die Druckplatte 7, 8 eingebrachte Kanäle läuft und somit den Pressspalt 5 bzw. des Holzwerkstoff 6 zusätzlich beheizt. Das im Holzwerkstoff 6 befindliche Wasser verdampft, und der Dampfdruck treibt Holzspäne seitlich aus dem Pressspalt heraus, was ohne die erfindungsgemäße Vorrichtung 1 zu großer Verschmutzung und in gefährdender Weise sogar zur Verbrennung der Fasern an den Zuleitungen für das Heizmedium führen kann.The heatable pressure plates 6, 7 are generally supplied with a heating medium, for example heating oil, via supply lines 11 and stub lines 12 running along the continuous press, which runs through channels introduced into the pressure plate 7, 8 and thus the press gap 5 or the wood material 6 additionally heated. The water in the wood material 6 evaporates, and the vapor pressure drives wood chips out of the side of the press nip, which, without the device 1 according to the invention, can lead to excessive contamination and, in a dangerous manner, even to the combustion of the fibers on the supply lines for the heating medium.

Aus diesem Grund weist die Vorrichtung 1 eine Auffangtrichteranordnung 15 mit einzelnen Trichtern 16 zwischen den Rahmen 13 auf. Die den Trichter bildenden Bleche können Wartungsklappen 17 aufweisen.For this reason, the device 1 has a collecting funnel arrangement 15 with individual funnels 16 between the frames 13. The sheets forming the funnel can have maintenance flaps 17.

Die Trichter sind so gestaltet, dass die seitlich aus dem Pressspalt 6 ausgeblasenen Späne direkt zu einer mechanischen Transportvorrichtung 18, in diesem Ausführungsbeispiel einer Förderschnecke 19.1, 19.2, zugeleitet werden. In diesen Förderschnecken 19.1, 19.2 werden die Späne zu einer Absaugeinrichtung 20 transportiert. Am Ende der Presse hat eine Absaugeinrichtung keinen schädlichen Einfluss mehr auf die Seitenkanten des Holzwerkstoffs 6.The funnels are designed such that the chips blown out laterally from the press nip 6 are fed directly to a mechanical transport device 18, in this exemplary embodiment a screw conveyor 19.1, 19.2. The chips are transported to a suction device 20 in these screw conveyors 19.1, 19.2. At the end of the press, a suction device no longer has any harmful influence on the side edges of the wood material 6.

In dem Ausführungsbeispiel der Figuren 1 und 2 sind zwei Förderschnecken 19.1 und 19.2 übereinander und überlappend angeordnet. Die Förderschnecke 19.1 übergibt das geförderte Material an Förderschnecke 19.2, die auch gleichzeitig die abgeführten Späne vom letzten Abschnitt der Auffangtrichteranordnung 15 aufnimmt. Durch die Verkürzung einer möglichen langen Schnecke auf zwei kürzere kann der Bauraum für die Antriebe verkleinert werden. Die Förderschnecke 19.2 übergibt die abgeführten Späne an die Absaugeinrichtung 20.In the embodiment of the Figures 1 and 2 are two screw conveyors 19.1 and 19.2 arranged one above the other and overlapping. The screw conveyor 19.1 transfers the conveyed material to the screw conveyor 19.2, which also simultaneously removes the chips removed from the last section of the Collecting funnel assembly 15 takes. By shortening a possible long screw to two shorter ones, the installation space for the drives can be reduced. The screw conveyor 19.2 transfers the removed chips to the suction device 20.

Die Förderschnecken 19.1, 19.2 und die Trichteranordnung 15 bilden auf jeder Seite der kontinuierlichen Doppelbandpresse 2 eine gemeinsame Baueinheit 21, die auf Schienen 22 über den Hallenboden 23 verfahrbar und somit von der kontinuierlichen Doppelbandpresse mehr oder weniger beabstandet werden kann. Damit kann beispielsweise ein Freiraum für Wartungsarbeiten geschaffen werden. Aus diesem Grund ist die Baueinheit 21 in Fig. 1 auf der rechten Seite in zwei unterschiedlichen Endpositionen E1 und E2 gezeichnet.The screw conveyors 19.1, 19.2 and the funnel arrangement 15 form a common structural unit 21 on each side of the continuous double belt press 2, which can be moved on rails 22 over the hall floor 23 and can thus be more or less spaced apart from the continuous double belt press. This can create space for maintenance work, for example. For this reason, the assembly 21 is in Fig. 1 drawn on the right side in two different end positions E1 and E2.
