Definitions
- the invention relates to a method for drying wooden boards, veneers or the like and to an apparatus for carrying out the method.
- the object of the invention is to provide a method and a device for drying wooden boards or the like, so that optimal drying conditions are ensured and the technical outlay is reduced.
- the linear support of the wooden boards ensures a minimal contact area and at the same time an improved flow around the wooden boards to be dried.
- the line support creates a specifically high pressure on the wood at relatively short intervals, which leads to a clamping and thus shape stabilization of the wooden boards during drying and a reduction in shrinkage, which also leads to a reduction in tension of the wood in the variable climatic conditions after Drying contributes. Due to the shape stabilization during drying, the wooden boards are so flat that they can also be stored for further processing.
- the line pressure on the wooden boards must be sufficient to restrict the freedom of movement of the wooden boards, but must not be so great that permanent impressions are created in the wooden surface.
- the line print is applied according to claim 2 at a distance of preferably 12 mm and should be at least 20 g / cm according to claim 3.
- the drying can be carried out in a continuous process according to claim 4 or stationary in a stack according to claim 5.
- the use of stacking plates also enables a fully automatic stacking process. So that the uppermost layer is also clamped sufficiently in a higher stack, either a corresponding bracing of the entire stack or a weight load from above is possible.
- the object of the invention is achieved by the features of claims 6 and 9, respectively.
- the wooden boards are clamped in a particularly uniform manner, and it is possible to fully automate when the wooden boards are placed and removed from the conveyor gap.
- the design of the spacers as a stacking plate has proven to be particularly favorable.
- the design of the spacers as a plate, which provides support sections on both sides of the plate, not only ensures uniform support spacing, but also a simplified stacking option. It is particularly advantageous if such a stacking plate is designed according to one of subclaims 11 to 13.
- a stacking plate 1 is located between two wooden board layers 2. By stacking additional stacking boards and wooden board layers, drying stacks of up to 200 layers can be formed.
- the stacking plate 1 consists of a zig / zag folded sheet made of stainless steel or aluminum, the upper and lower vertices of which serve as support sections 3 for the wooden board layers or veneer layers.
- These wooden boards are placed on a stacking plate in such a way that their grain or longitudinal fibers run transversely to the support sections, which in turn are straight and linear. This results in a linear contact with a minimal support or contact surface for the wooden boards, at the same time creating sufficient space between the support sections for cross ventilation along the ribs. Channels which are parallel to one another are thus formed between the stacking plate and the adjacent board layers and ensure unimpeded circulation of a drying medium.
- the stacking plate can be provided with breakthroughs, not shown, in order to ensure a cross flow, particularly when a drying medium is forced to circulate, and thus to achieve temperature and moisture compensation in the channels.
- a drying stack consisting of up to 200 layers of wooden boards is subjected to a stationary drying process in a drying chamber, which means a significantly lower technical effort compared to continuous drying and thus also reduces costs.
- the stacking plate can also be formed with rounded shaft apices.
- ceramic, plastic or light metal alloys can also be used as the material for the stacking plate.
- the stacking plate can also be provided with various coatings which are resistant to the substances separated from the wood during the drying process. Basically, the material, shape, thickness and, if necessary, coating of the stacking panel should be selected depending on the nature of the wooden boards or veneers to be dried and the stack height.
- the principle of the invention of clamping the wooden boards or wood veneers under linear support sections running transversely to the longitudinal grain is also suitable for the continuous process.
- two endless conveyor belts 4 and 5 arranged one above the other are used, the lower and upper parts 6 and 7 of which delimit a parallel passage gap 8, the height of which corresponds to the thickness of the wooden boards 9 conveyed through the gap.
- the lower conveyor belt 4 has a leading section 10 for placing the wooden boards 9 before entering the passage gap. Accordingly, a trailing section can be provided at the end of the passage gap.
- the conveyor belts 4 and 5 of FIG. 2 are zig / zag-shaped folded belts, which rest with their apex 11 on the wooden board under a predetermined pressure, which can be exercised according to a schematic indication by the arrows 13 via a pressure plate 14, so that a line pressure of 20 g / cm on both sides is exerted through the apex 11 on the wooden boards.
- the distance between the apex 11, the height of the zigzag fold and the material thickness can be the same as for the stacking plate.
- the passage gap is located at least in the middle section between the leading and trailing sections in a drying oven.
- link chain belts 15 and 16 are provided for conveying the boards and have round bars 17 for supporting the wooden boards, which, like the apex of the belts according to FIG. 2, extend across the width of the conveyor belts transversely to the conveying direction F. extend so that here, too, a line pressure can be exerted transversely to the longitudinal direction of the fibers on the wooden boards.
- the height of the round bars i.e. their diameter can correspond to the height of the stacking plate according to FIG. 1. The same applies to the distance a between the round bars.
- the loading of the strips for clamping the wooden boards can take place as in the case of FIG. 2.
- a method and an apparatus for drying wooden boards are disclosed, in which the latter are clamped on both sides under line pressure transversely to the fiber direction in a drying apparatus.

Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zum Trocknen von Holzbrettchen, Furnieren oder dergleichen sowie auf eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for drying wooden boards, veneers or the like and to an apparatus for carrying out the method.
Für das Trocknen von dünnen Holzbrettchen, Holzfunieren oder dergleichen werden bisher im wesentlichen nur zwei Verfahren angewendet, und zwar die Trocknung im Durchlaufverfahren sowie die stationäre Trocknung in einer Trockenkammer z. B.. Bei der Durchlauftrocknung wird eine Brettchenlage auf einen Bandförderer oder auch Rollenförderer durch einen Ofen gefördert. Diese Trocknung ist häufig nicht ausreichend effektvoll, wenn es sich um Holz unterschiedlichen Trocknungsgrads und Holz größerer Materialdicke sowie kleinerer Abmessungen handelt. Im besonderen führt die unvermeidbare Verwerfung von dickeren Brettchen oder Furnieren bei diesem Verfahren zur Unbrauchbarkeit in verschiedenen Verwendungsfällen.For drying thin wooden boards, wood veneers or the like, essentially only two processes have been used so far, namely drying in a continuous process and stationary drying in a drying chamber, for. B .. In continuous drying, a board layer is conveyed on a belt conveyor or roller conveyor through an oven. This drying is often not sufficiently effective when it comes to wood with different degrees of drying and wood with a larger material thickness and smaller dimensions. In particular, the inevitable warping of thicker boards or veneers in this process leads to uselessness in various applications.
Bei der stationären Trocknung werden Brettchen in mehreren Einzellagen übereinander jeweils unter Zwischenschaltung von Abstandslatten gestapelt und durch Luftaustausch der Freiräume zwischen den Abstandslatten der Lagen getrocknet. Eine solche Trocknung bedeutet im automatisierten Zustand einen sehr hohen technischen Aufwand bei relativ geringer Leistung. Die Abstandslatten müssen in relativ engen, mehr oder weniger genau festgelegten Abständen zueinander angeordnet werden, um eine möglichst gleichmäßige Trocknung zu gewährleisten und Verwerfungen der gestapelten Brettchenlagen zu vermeiden. Daher ist der Aufbau eines solchen Stapels ein zeitintensiver Arbeitsvorgang. Ein wesentlicher Nachteil bei dieser Arbeitsweise besteht darin, daß die relativ großen Auflagebereiche der meistens rechteckig ausgebildeten Abstandslatten das Entweichen von Feuchtigkeit aus den Holzlagen erschwert, so daß keine günstigen Trocknungsbedingungen gewährleistet werden können.In the case of stationary drying, boards are stacked in several individual layers one above the other, with spacer slats in between, and dried by exchanging air between the spacer slats of the layers. In the automated state, such drying means a very high technical outlay with a relatively low output. The spacer slats must be arranged at relatively narrow, more or less precisely defined distances from one another in order to ensure drying that is as uniform as possible and to avoid warping of the stacked board layers. Therefore, building such a stack is a time consuming process. A major disadvantage of this procedure is that the relatively large support areas of the mostly rectangular spacer slats make it difficult for moisture to escape from the wooden layers, so that no favorable drying conditions can be guaranteed.
Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung zum Trocknen von Holzbrettchen oder dergleichen zu schaffen, so daß optimale Trocknungsbedingungen gewährleistet und der technische Aufwand gemindert wird.The object of the invention is to provide a method and a device for drying wooden boards or the like, so that optimal drying conditions are ensured and the technical outlay is reduced.
Diese Aufgabe wird hinsichtlich des Verfahrens durch die gekennzeichneten Merkmale des Patentanspruchs 1 gelöst. Die linienförmige Stützung der Holzbrettchen gewährleistet eine minimale Auflagefläche und gleichzeitig dadurch eine verbesserte Umströmung der zu trocknenden Holzbrettchen. Durch die Linien-Auflage bildet sich ein spezifisch hoher Druck auf das Holz in verhältnismäßig kurzen Abständen, was zu einer Einspannung und damit Formstabilisierung der Holzbrettchen während der Trocknung führt und zu einer Schwundreduzierung, die auch zu einem Spannungsabbau des Holzes in den variablen Klimazuständen nach der Trocknung beiträgt. Durch die Formstabilisierung während der Trocknung weisen die Holzbrettchen eine derartige Planität auf, daß sie für die Weiterverarbeitung auch magaziniert werden können.With regard to the method, this object is achieved by the characterized features of patent claim 1. The linear support of the wooden boards ensures a minimal contact area and at the same time an improved flow around the wooden boards to be dried. The line support creates a specifically high pressure on the wood at relatively short intervals, which leads to a clamping and thus shape stabilization of the wooden boards during drying and a reduction in shrinkage, which also leads to a reduction in tension of the wood in the variable climatic conditions after Drying contributes. Due to the shape stabilization during drying, the wooden boards are so flat that they can also be stored for further processing.
Der Liniendruck auf die Holzbrettchen muß ausreichen, die Bewegungsfreiheit der Holzbrettchen einzuschränken, darf jedoch nicht so groß sein, daß in der Holzoberfläche bleibende Eindrückungen erzeugt werden. Der Liniendruck wird gemäß Patentanspruch 2 in einem Abstand von vorzugsweise 12 mm aufgebracht und sollte gemäß Patentanspruch 3 mindestens 20 g/cm betragen.The line pressure on the wooden boards must be sufficient to restrict the freedom of movement of the wooden boards, but must not be so great that permanent impressions are created in the wooden surface. The line print is applied according to
Die Trocknung kann im Durchlaufverfahren gemaß Patentanspruch 4 oder auch stationär im Stapel gemäß Patentanspruch 5 erfolgen. Die Verwendung von Stapelplatten ermöglicht ebenfalls einen vollautomatischen Stapelvorgang. Damit in einem höheren Stapel auch die oberste Lage ausreichend eingespannt wird, ist entweder eine entsprechende Verspannung des gesamten Stapels oder auch eine Gewichtsbelastung von oben möglich.The drying can be carried out in a continuous process according to claim 4 or stationary in a stack according to
Hinsichtlich der Vorrichtung wird die erfindungsgemäße Aufgabe durch die Merkmale des Patentanspruchs 6 bzw. 9 gelöst. Bei Verwendung von Förderbändern ergibt sich eine besonders gleichförmige Einspannung der Holzbrettchen, wobei ein Vollautomatisieren bei Auflage und Entnahme der Holzbrettchen aus dem Förderspalt möglich ist. Im Falle der Stapelung bei stationärer Trocknung erweist sich die Ausbildung der Abstandhalter als Stapelplatte als besonders günstig. Die Ausbildung der Abstandhalter als Platte, die nach beiden Plattenseiten hin Auflageabschnitte liefert, gewährleistet nicht nur gleichförmigen Stützabstand, sondern eine vereinfachte Stapelmöglichkeit. Dabei ist es von besonderem Vorteil, wenn eine solche Stapelplatte nach einem der Unteransprüche 11 bis 13 gestaltet wird.With regard to the device, the object of the invention is achieved by the features of claims 6 and 9, respectively. When using conveyor belts, the wooden boards are clamped in a particularly uniform manner, and it is possible to fully automate when the wooden boards are placed and removed from the conveyor gap. In the case of stacking with stationary drying, the design of the spacers as a stacking plate has proven to be particularly favorable. The design of the spacers as a plate, which provides support sections on both sides of the plate, not only ensures uniform support spacing, but also a simplified stacking option. It is particularly advantageous if such a stacking plate is designed according to one of
Für die Praxis hat sich eine Stapelplatte in Edelstahl oder Aluminium mit einer Stärke von 1 mm besonders bewährt, bei der die benachbarten Rippen einen Abstand von 12 mm haben und eine Höhe von 6 mm haben.In practice, a stacking plate made of stainless steel or aluminum with a thickness of 1 mm, in which the adjacent ribs are 12 mm apart and 6 mm high, has proven particularly useful.
Die Erfindung wird im folgenden anhand mehrerer Ausführungsbeispiele unter Bezugnahme auf die Zeichnungen näher erläutert.
- Fig. 1 zeigt einen beliebigen Ausschnitt eines Trockenstapels für stationäre Trocknung.
- Fig. 2 und 3 zeigen im Teilschnitt Förderbänder für Durchlauftrocknung.
- 1 shows an arbitrary section of a drying stack for stationary drying.
- 2 and 3 show in partial section conveyor belts for continuous drying.
Bei einem Stapel nach Fig. 1 befindet sich eine Stapelplatte 1 zwischen zwei Holzbrettchenlagen 2. Durch entsprechende Schichtung weiterer Stapelplatten und Holzbrettchenlagen können Trocknungsstapel bis zu 200 Lagen gebildet werden.In the case of a stack according to FIG. 1, a stacking plate 1 is located between two
Im Falle der Figur besteht die Stapelplatte 1 aus einem zick/zack-förmig gefalteten Blech aus rostfreiem Stahlblech oder Aluminium, dessen obere und untere Scheitelpunkte jeweils als Auflageabschnitte 3 für die Holzbrettchenlagen oder auch Funierlagen dienen. Diese Holzbrettchen werden so auf eine Stapelplatte gelegt, daß ihre Maserung bzw. Längsfasern quer zu den Auflageabschnitten verlaufen, die ihrerseits geradlinig und linienförmig sind. Es ergibt sich dadurch eine linienförmige Berührung mit minimaler Auflage bzw. Kontaktfläche für die Holzbrettchen, wobei gleichzeitig ein ausreichender Freiraum zwischen den Auflageabschnitten für eine Querbelüftung entlang der Rippen geschaffen wird. Zwischen der Stapelplatte und den anliegenden Brettchenlagen werden also zueinander parallele Kanäle gebildet, die eine unbehinderte Zirkulation eines Trocknungsmediums gewährleisten. Die Stapelplatte kann mit nicht gezeigten Durchbrüchen versehen sein, um eine Querströmung insbesondere bei einer erzwungenen Zirkulation eines Trocknungsmediums zu gewährleisten und damit einen Temperatur- und Feuchtigkeitsausgleich in den Kanälen zu erreichen. Bei verhältnismäßig kurzem Abstand der Auflageabschnitte 3 ergibt sich in Längsrichtung der jeweiligen Holzbrettchen eine häufige Stützung, die der Formstabilisierung während der Trocknung dient. Die kurzen Abstände der Auflageabschnitte ermöglichen es auch, sehr kurze Holzbrettchen zu trocknen. Bei dem vorzugsweise gewählten Abstand a der Auflageabschnitte 3 von 12 mm und der bevorzugten Höhe h einer solchen Stapelplatte von 6 mm ergibt sich ein hervorragender Wirkungsgrad hinsichtlich der Formstabilisierung sowie der Abfuhr von Feuchtigkeit und Luft, daß die Brettchen mit einer solchen Planität nach dem Trocknungsvorgang erhalten werden, die eine Magazinierung für die Weiterverarbeitung ermöglicht.In the case of the figure, the stacking plate 1 consists of a zig / zag folded sheet made of stainless steel or aluminum, the upper and lower vertices of which serve as
Ein aus bis zu 200 Holzbrettchenlagen bestehender Trocknungsstapel wird in einer Trockenkammer einem stationären Trocknungsvorgang unterzogen, der gegenüber einer Durchlauftrocknung einen wesentlich geringeren technischen Aufwand bedeutet und damit auch Kosten reduziert.A drying stack consisting of up to 200 layers of wooden boards is subjected to a stationary drying process in a drying chamber, which means a significantly lower technical effort compared to continuous drying and thus also reduces costs.
Die Stapelplatte kann aus fertigungstechnischen Gründen auch mit abgerundeten Wellenscheiteln ausgebildet werden. Als Material für die Stapelplatte können neben Stahlblech auch Keramik, Kunststoff oder Leichtmetallegierungen verwendet werden. Die Stapelplatte kann auch mit verschiedenen Beschichtungen versehen werden, die gegenüber den beim Trocknungsvorgang aus dem Holz abgesonderten Substanzen beständig sind. Grundsätzlich sind Material, Form, Dicke und gegebenfalls Beschichtung der Stapelplatte in Abhängigkeit von der Beschaffenheit der zu trocknenden Holzbrettchen oder Furnieren und der Stapelhöhe zu wählen.For reasons of production technology, the stacking plate can also be formed with rounded shaft apices. In addition to sheet steel, ceramic, plastic or light metal alloys can also be used as the material for the stacking plate. The stacking plate can also be provided with various coatings which are resistant to the substances separated from the wood during the drying process. Basically, the material, shape, thickness and, if necessary, coating of the stacking panel should be selected depending on the nature of the wooden boards or veneers to be dried and the stack height.
Das Erfindungsprinzip der Einspannung der Holzbrettchen oder Holzfurniere unter quer zur Längsmaserung verlaufenden linienförmigen Auflageabschnitten beim Trocknungsvorgang eignet sich auch für das Durchlaufverfahren. Für einen solchen Fall werden zwei endlose, im Abstand übereinander angeordnete Förderbänder 4 und 5 verwendet, deren unteres bzw. oberes Teil 6 bzw. 7 einen parallelen Durchlaufspalt 8 begrenzt, dessen Höhe der Stärke der durch den Spalt geförderten Holzbrettchen 9 entspricht. Das untere Förderband 4 hat einen Vorlaufabschnitt 10 für das Auflegen der Holzbrettchen 9 vor dem Eintritt in den Durchlaufspalt. Entsprechend kann am Ende des Durchlaufspalts ein Nachlaufabschnitt vorgesehen sein.The principle of the invention of clamping the wooden boards or wood veneers under linear support sections running transversely to the longitudinal grain is also suitable for the continuous process. In such a case, two
Die Förderbänder 4 und 5 nach Fig. 2 sind zick/zack-förmig gefaltete Bänder, die mit ihren Scheiteln 11 an den Holzbrettchen unter einem vorgegebenen Druck anliegen, der gemäß schematischer Andeutung durch die Pfeile 13 über eine Druckplatte 14 ausgeübt werden kann, so daß ein beidseitiger Liniendruck von 20 g/cm durch die Scheitel 11 auf die Holzbrettchen ausgeübt wird. Der Abstand der Scheitel 11, die Höhe der Zick-Zack-Faltung und die Materialstärke können genauso wie bei der Stapelplatte sein. Der Durchlaufspalt befindet sich zumindest im mittleren Abschnitt zwischen Vorlauf- und Nachlaufabschnitt in einem Trocknungsofen.The
Bei der Ausführungsform nach Fig. 3 sind zur Förderung der Brettchen Gliederkettenbänder 15 und 16 vorgesehen, die zur Stützung der Holzbrettchen Rundstäbe 17 haben, die sich, wie auch die Scheitel der Bänder nach Fig. 2, quer zur Förderrichtung F über die Breite der Förderbänder erstrecken, so daß auch hier ein Liniendruck quer zur Faserlängsrichtung auf die Holzbrettchen ausgeübt werden kann. Die Höhe der Rundstäbe, d.h. ihr Durchmesser, kann der Höhe der Stapelplatte nach Fig. 1 entsprechen. Entsprechendes gilt auch für den Abstand a der Rundstäbe. Die Belastung der Bänder zur Einspannung der Holzbrettchen kann wie im Fall der Fig. 2 erfolgen.In the embodiment according to FIG. 3,
Offenbart wird ein Verfahren und eine Vorrichtung zum Trocknen von Holzbrettchen, bei dem letztere beidseitig unter Liniendruck quer zur Faserrichtung in einer Trocknungsvorrichtung eingespannt werden.A method and an apparatus for drying wooden boards are disclosed, in which the latter are clamped on both sides under line pressure transversely to the fiber direction in a drying apparatus.
