Verbindung von Teilplatten von Abrollplatten in einer kontinuierlichen PresseConnection of partial plates of rolling plates in a continuous press
Die vorliegende Erfindung betrifft kontinuierliche Pressen zur Herstellung von Platten durch Pressen eines Materials, insbesondere von Holzwerkstoffplatten oder Laminatplatten. Die vorliegende Erfindung betrifft insbesondere die Verbindung von Teilplatten der Abrollplatten in einer kontinuierlichen Presse.The present invention relates to continuous presses for producing sheets by pressing a material, in particular wood-based panels or laminate panels. The present invention relates in particular to the connection of sub-plates of the rolling plates in a continuous press.
Für die Herstellung von Platten wie beispielsweise Holzwerkstoffplatten, Laminatplatten, Spanplatten, Faserplatten und dergleichen werden kontinuierliche Pressen verwendet. In derartigen Pressen wird das zu pressende Material - das Pressgut - zwischen einem Pressenoberteil und einem Pressenunterteil mit Hilfe von einem oberen Stahlblechpressband und einem unteren Stahlblechpressband kontinuierlich gepresst. Dabei laufen die Stahlblechbänder jeweils endlos um Umlenk- und Antriebswalzen.Continuous presses are used for the production of boards such as wood-based boards, laminate boards, chipboard, fiberboard and the like. In such presses, the material to be pressed - the pressed material - is pressed continuously between a press upper part and a press lower part by means of an upper pressed steel strip and a lower pressed steel strip. The steel strips run endlessly around deflection and drive rollers.
In bekannten kontinuierlichen Pressen stützen sich die Stahlblechpressbänder in dem Pressbereich unter Zwischenschaltung von Walzkörpern an Abrollplatten ab. Diese Abrollplatten weisen normalerweise Heizkanäle auf mit welchen das Pressgut erhitzt wird. Hierfür wird durch die Heizkanäle ein Wärmeträgerelement geleitet, wie beispielsweise ein Wärmeträgeröl, Heißwasser oder Dampf, welches durch ein außerhalb der Abrollplatte angeordnetes Heizsystem bereitgestellt wer- den kann. Mit Hilfe von geeigneten Elementen, wird auf die Abrollplatten ein Druck ausgeübt, der über die Walzkörper und das Stahlblechpressband auf das Pressgut weitergeleitet wird. In bekannten Systemen wird hierfür eine Anordnung von Press- Zylindern verwendet. Diese Presszylinder sind normalerweise an der einen Seite am Rahmen der kontinuierlichen Presse und an der anderen Seite an einer Abrollplatte befestigt. An der anderen Abrollplatte ist im gleichen Bereich jeweils ein Gegenmittel angeordnet. In den bekannten kontinuierlichen Pressen wird dies durch einen in sich geschlossenen Pressenrahmen realisiert. Dadurch kann mit Hilfe der Presszylinder und der Gegenmittel zwischen der Abrollplatte im Pressoberteil und der Abrollplatte im Pressunterteil ein Druck aufgebaut bzw. gehalten werden kann.In known continuous presses, the steel plate press belts in the pressing area are supported on rolling plates with the interposition of rolling bodies. These rolling plates normally have heating channels with which the material to be pressed is heated. For this purpose, a heat transfer element is passed through the heating channels, such as a heat transfer oil, hot water or steam, which can be provided by a heating system arranged outside of the rolling plate. With the help of suitable elements, a pressure is exerted on the rolling plates, which is forwarded via the rolling elements and the steel plate press belt on the pressed material. In known systems, an arrangement of press cylinders is used for this purpose. These press cylinders are usually fixed on one side to the frame of the continuous press and on the other side to a rolling plate. At the other rolling plate in each case an antidote is arranged in the same area. In the known continuous presses this is realized by a self-contained press frame. As a result, with the help of the pressing cylinder and the counter-agent between the rolling plate in the press upper part and the rolling plate in the press bottom, a pressure can be built up or maintained.
In Abhängigkeit von der Breite der Abrollplatte - also der Erstreckung in der Ab- rollplatte quer zur Durchlaufrichtung des zu pressenden Materials — werden grundsätzlich ein oder mehrere Presszylinder in einer Reihe quer zur Durchlaufrichtung der kontinuierlichen Presse angeordnet.Depending on the width of the rolling plate - ie the extent in the Abroll- roll transverse to the direction of passage of the material to be pressed - one or more press cylinders are arranged in a row transverse to the direction of passage of the continuous press in principle.
Da die bekannten kontinuierlichen Pressen wesentlich länger sind als die verwen- deten Abrollplatten, enthalten die kontinuierlichen Pressen in dem Pressoberteil und in dem Pressunterteil jeweils mehrere Teilplatten, die miteinander verbunden sind. Wie in DE 43 16 441 Cl beispielsweise beschrieben ist, können die Teilplatten mit Hilfe von Nut- und Federelementen auf den Teilplatten verbunden werden.Since the known continuous presses are significantly longer than the used Abrollplatten used, the continuous presses in the press upper part and in the press base each have a plurality of sub-panels which are interconnected. As described in DE 43 16 441 Cl, for example, the sub-plates can be connected by means of tongue and groove elements on the sub-plates.
An den Verbindungsstellen weisen die obere und die untere Abrollplatte eine geringere Steifigkeit auf. Hierdurch wird die Verformung in einem Abrollplattenab- schnitt, der eine Verbindungsstelle aufweist, wesentlich größer als in einem Abrollplattenabschnitt, der keine Verbindungsstelle aufweist. Dadurch wird der Druck ungleichmäßig auf das Pressgut übertragen, was zu einer ungewünschten Belastung des Pressguts führen kann. Darüber hinaus können durch den mangelnden Gegendruck des Pressgutes Dampfausblasungen an den Seiten der Presse ent- stehen, durch die die Maschinen nicht nur verschmutzt wird, sondern der derart ausgeblasene Schmutz erhöht auch die Brandgefahr in der kontinuierlichen Presse.At the joints, the upper and lower rolling plates have a lower rigidity. As a result, the deformation in a Abrollplattenab- section having a junction, much larger than in a Abrollplattenabschnitt which has no connection point. As a result, the pressure is transmitted unevenly to the pressed material, which can lead to an undesirable loading of the pressed material. In addition, due to the lack of back pressure of the material to be pressed, steam blows can be generated on the sides of the press. not only pollutes the machines, but the so-blown dirt also increases the risk of fire in the continuous press.
Daher hat die vorliegende Erfindung die Aufgabe eine kontinuierliche Presse mit Abrollplatten bestehend aus mehreren Teilplatten bereitzustellen, bei welcher die Teilplatten derart miteinander verbunden sind, dass an den Verbindungsstellen die oben beschriebenen Nachteile nicht auftreten.Therefore, the present invention has the object to provide a continuous press with Abrollplatten consisting of a plurality of sub-plates, in which the sub-plates are connected to one another such that at the joints the disadvantages described above do not occur.
Diese Aufgabe wird durch eine kontinuierliche Presse gemäß dem unabhängigen Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen sind Gegenstand der abhängigen Ansprüche.This object is achieved by a continuous press according to independent claim 1. Advantageous embodiments and further developments are the subject of the dependent claims.
Die kontinuierliche Presse zur Herstellung von Platten durch Pressen von entspre- chendem Material gemäß der vorliegenden Erfindung weist ein Pressoberteil und ein Pressunterteil auf, die jeweils ein kontinuierliches Stahlblechpressband, mehrere Walzkörper und eine aus mehreren Teilplatten bestehende Abrollplatte aufweisen. In mindestens einem von dem Pressoberteil oder Pressunterteil sind Presszylinder angeordnet, die zusammen mit entsprechenden gegenüberliegenden Ge- genmitteln in dem anderen von dem Pressoberteil oder Pressunterteil einen Druck zwischen den Abrollplatten bilden. Die Presszylinder und die Gegenmittel sind jeweils quer zur Durchlaufrichtung der kontinuierlichen Presse an der jeweiligen Abrollplatte gereiht angeordnet und zwischen zwei benachbarten Reihen von Presszylindern beziehungsweise Gegenmitteln befindet sich jeweils ein Abroll- plattenabschnitt.The continuous press for producing plates by pressing of corresponding material according to the present invention comprises a press top and a press bottom, each having a continuous steel plate press belt, a plurality of rolling elements and a rolling plate consisting of a plurality of sub-plates. In at least one of the press top or press bottom, press cylinders are arranged which together with corresponding opposing counterparts in the other of the press top or press bottom form a pressure between the roll plates. The pressing cylinders and the counter-means are each arranged in a row transversely to the direction of passage of the continuous press on the respective rolling plate, and between each two adjacent rows of pressing cylinders or counter-means there is a respective rolling-off plate section.
Erfindungsgemäß ist die Verbindung zwischen zwei Teilplatten der einen Abrollplatte in einem anderen Abrollplattenabschnitt angeordnet ist als die Verbindung zwischen zwei Teilplatten der anderen Abrollplatte. Überraschenderweise hat sich gezeigt, dass bereits diese geringe konstruktive Änderung einen großen Einfluss auf die Qualität des gepressten Materials hat. Im Vergleich zu den bekannten Anordnungen der Verbindungen von Abrollplatten hat die erfindungsgemäße Anordnung eine wesentlich höhere Steifigkeit. Deshalb wird bei der erfindungsgemäßen kontinuierlichen Presse der Druck wesentlich gleichmäßiger auf das Pressgut übertragen. Dies bewirkt, dass die mit der erfindungsgemäßen kontinuierlichen Presse hergestellten Platten wesentlich gleichmäßiger sind als vergleichbare Platten, die mit im Stand der Technik bekannten kontinuierlichen Pressen hergestellt wurden. Darüber hinaus ist die Brandgefahr bei der erfindungsgemäßen kontinuierlichen Presse wesentlich geringer, da durch die größere Steifigkeit Dampfausblasungen an den Seiten der Presse verhindert werden können. Außerdem hat sich gezeigt, dass durch die erfindungsgemäße Anordnung der Verbindungen der Pressprozess beschleunigt werden kann. Weiter kann bei der erfindungsgemäßen kontinuierlichen Presse im Vergleich zu den im Stand der Technik bekannten Pressen der Abstand zwischen den benachbarten Presszylindern, d.h. die Länge der Abrollplattenabschnitte vergrößert werden und/oder die Dicke der Abrollplatten reduziert werden.According to the invention, the connection between two partial plates of a rolling plate is arranged in a different Abrollplattenabschnitt than the connection between two partial plates of the other Abrollplatte. Surprisingly, it has been shown that even this small structural change has a great influence on the quality of the pressed material. Compared to the known arrangements of the compounds of rolling plates, the arrangement according to the invention has a much higher rigidity. Therefore, in the continuous press according to the invention, the pressure is transmitted much more uniformly to the pressed material. This causes the panels made with the continuous press according to the invention to be substantially more uniform than comparable panels made using continuous presses known in the art. In addition, the risk of fire in the continuous press according to the invention is substantially lower, as can be prevented by the greater rigidity Dampfausblasungen on the sides of the press. In addition, it has been found that can be accelerated by the inventive arrangement of the compounds of the pressing process. Further, in the continuous press according to the present invention, as compared with the presses known in the art, the distance between the adjacent press cylinders, that is, the length of the rolling plate sections, can be increased and / or the thickness of the rolling plates can be reduced.
In einer bevorzugten Ausführungsform der vorliegenden Erfindung weisen die Endbereiche der Teilplatten jeweils Verbindungselemente auf mit denen die Teilplatten untereinander verbunden werden. Weiter bevorzugt werden Schrauben verwendet, um die Verbindungselemente der Teilplatten miteinander zu verbinden.In a preferred embodiment of the present invention, the end regions of the partial plates each have connecting elements with which the partial plates are interconnected. More preferably, screws are used to connect the connecting elements of the sub-panels together.
Weitere Vorteile und Merkmale der Erfindung sind der nachfolgenden detaillierten Beschreibung zu entnehmen, in welcher die Erfindung detaillierter und in Bezug auf die in den beigefügten Zeichnungen dargestellten Ausführungsbeispiele beschrieben wird.Further advantages and features of the invention will become apparent from the following detailed description, in which the invention will be described in more detail and with reference to the embodiments illustrated in the accompanying drawings.
m den Zeichnungen zeigt: Fig. 1 eine Skizze des Aufbaus einer kontinuierlichen Presse, wie sie im Rahmen der vorliegenden Erfindung verwendet werden kann; und Fig. 2 einen Ausschnitt aus einer kontinuierlichen Presse mit der erfindungsgemäßen Anordnung der Abrollplatten.In the drawings: Fig. 1 is a sketch of the structure of a continuous press, as it can be used in the context of the present invention; and Fig. 2 shows a detail of a continuous press with the inventive arrangement of the rolling plates.
Figur 1 zeigt skizzenhaft den Aufbau einer kontinuierlichen Presse 1 , wie sie im Zusammenhang mit der vorliegenden Erfindung verwendet werden kann. Die Presse 1 enthält ein Pressoberteil 2 und eine Pressunterteil 3. In dem Pressoberteil 2 und in dem Pressunterteil 3 befindet sich jeweils ein umlaufendes Stahlblech- pressband 4, das mit Hilfe von entsprechenden Umlenkrollen gefuhrt wird. Dabei bilden die beiden Stahlblechpressbänder 4 in einem Pressbereich einen Spalt in dem das Pressgut in der Durchlaufrichtung 9 gepresst wird.Figure 1 shows in outline the construction of a continuous press 1, as it can be used in connection with the present invention. The press 1 contains a press upper part 2 and a press lower part 3. In the press upper part 2 and in the press lower part 3 is in each case a circulating pressed steel sheet press belt 4, which is guided by means of corresponding deflection rollers. In this case, the two steel press belts 4 in a pressing region form a gap in which the pressed material is pressed in the direction of passage 9.
In dem Pressbereich sind an der Rückseite der Stahlblechbänder 4 Walzkörper 5 angeordnet. In dem in Figur 1 gezeigten Beispiel handelt es sich dabei um Stahlstangen, die mit Hilfe einer Kette oder einer anderen geeigneten Stangenumlauf- einrichtung über einen Umlaufweg (nicht gezeigt) geführt werden.In the pressing region 4 rolling elements 5 are arranged at the back of the steel strips. In the example shown in FIG. 1, these are steel rods that are guided by means of a chain or another suitable rod circulation device via a circulation path (not shown).
Das Pressoberteil 2 und das Pressunterteil 3 weisen auch jeweils Abrollplatten 6 auf. In diesen Abrollplatten 6 befinden sich Heizkanäle mit denen das Pressgut erhitzt werden kann. Die Abrollplatten üben darüber hinaus über die Walzkörper 5 und die Stahlblechbänder 4 Druck auf das Pressgut aus.The press upper part 2 and the press lower part 3 also have respective rolling plates 6. In these rolling plates 6 are heating channels with which the pressed material can be heated. In addition, the rolling plates exert pressure on the pressed material via the rolling elements 5 and the steel sheet strips 4.
Figur 2 zeigt in einer Seitenansicht einen Ausschnitt aus einer kontinuierlichen Presse gemäß der vorliegenden Erfindung. In Figur 2 wird genauer verdeutlicht, wie der Druck zwischen den Abrollplatten 6 gebildet wird. In dem in Figur 2 gezeigten Ausführungsbeispiel sind an dem Rahmen der kontinuierlichen Presse Presszylindern 7 angeordnet. In der Seitenansicht ist jeweils nur einer der in Reihe angeordneten Presszylinder 7 zu sehen. Die Anzahl der in Reihe angeordneten Presszylinder 7 hängt von der Breite der Abrollplatte 6 beziehungsweise der her- zustellenden Platte ab. Dabei kann die Anzahl der Presszylinder 7 auch über die Länge der kontinuierlichen Presse 1 variieren.Figure 2 shows a side view of a section of a continuous press according to the present invention. FIG. 2 shows in greater detail how the pressure is formed between the rolling plates 6. In the exemplary embodiment shown in FIG. 2, pressing cylinders 7 are arranged on the frame of the continuous press. In the side view only one of the arranged in series pressing cylinder 7 can be seen in each case. The number of pressing cylinders 7 arranged in series depends on the width of the rolling plate 6 or the delivering plate. The number of press cylinders 7 can also vary over the length of the continuous press 1.
Während in dem in Figur 2 gezeigten Beispiel bei der oberen Abrollplatte 6 der Druck durch Presszylinder 7 gebildet wird, befindet sich an der entsprechenden, d.h. an der gegenüberliegenden Stelle der unteren Abrollplatte 6 ein Gegenmittel 8. Zwischen dem Gegenmittel 8 und dem Presszylinder 7 wird der Druck aufgebaut, der über die Abrollplatten 6, die Walzkörper 5 und die Stahlblechpressbänder 4 auf das zu pressende Material ausgeübt wird. Dabei können die Gegenmittel aktiv oder passiv sein. Ein Beispiel für ein aktives Gegenmittel ist eine verstellbare Unterstützung der unteren Abrollplatte 6, während ein passives Gegenmittel beispielsweise durch eine feste, d.h. nicht verstellbare Unterstützung der unteren Abrollplatte 6 realisiert werden kann.While in the example shown in Fig. 2, the pressure of the upper rolling plate 6 is formed by the pressing cylinder 7, the corresponding one, i.e., the pressure is applied to the upper rolling plate 6. At the opposite point of the lower rolling plate 6 an antidote 8. Between the antidote 8 and the pressing cylinder 7, the pressure is built up, which is exerted on the rolling plates 6, the rolling body 5 and the steel press belts 4 on the material to be pressed. The antidotes may be active or passive. An example of an active antidote is an adjustable support of the lower roll-off plate 6, while a passive antidote may be provided, for example, by a fixed, i.e. non-adjustable support of the lower rolling plate 6 can be realized.
Der zwischen zwei benachbarten Reihen von Presszylindern 7 beziehungsweise Gegenmitteln 8 liegende Abschnitt der Abrollplatte 6 wird im Rahmen der vorliegenden Erfindung als Abrollplattenabschnitt 10 bezeichnet. Erfindungsgemäß befindet sich die Verbindung I Ia zwischen zwei Teilplatten 6a, 6b der oberen Abrollplatte 6 in einem anderen Abrollplattenabschnitt 10 als die Verbindung I Ib zwischen zwei Teilplatten 6c, 6d der unteren Abrollplatte 6. Somit wird sichergestellt, dass in einem Abrollplattenabschnitt 10 immer nur die Verbindung zwischen zwei Teilplatten angeordnet ist. Abrollplattenabschnitte in denen sowohl in der oberen Abrollplatte 6 als auch in der unteren Abrollplatte 6 Verbindungen zwischen den jeweiligen Teilplatten vorliegen, wie dies im Stand der Technik üblich ist, werden dadurch verhindert.The section of the rolling plate 6 lying between two adjacent rows of pressing cylinders 7 and counter-means 8 is referred to as a rolling-off plate section 10 in the context of the present invention. According to the invention, the connection 11a between two partial plates 6a, 6b of the upper rolling plate 6 is in a different rolling plate section 10 than the connection 11b between two partial plates 6c, 6d of the lower rolling plate 6. Thus, it is ensured that in a rolling plate section 10 only the Connection between two sub-plates is arranged. Abrollplattenabschnitte in which present in both the upper Abrollplatte 6 and in the lower Abrollplatte 6 connections between the respective sub-plates, as is customary in the art, thereby prevented.
Wie in Figur 2 angedeutet, weisen die Endbereiche der Teilplatten jeweils Verbindungselemente auf mit denen die Teilplatten untereinander verbunden werden. Dabei können die Verbindungselemente der Teilplatten beispielsweise mit Bolzen verbunden werden. Somit wird durch die vorliegenden Erfindung erstmals eine kontinuierliche Presse mit Abrollplatten bestehend aus mehreren Teilplatten bereitgestellt, bei der die Teilplatten derart miteinander verbunden sind, dass die im Stand der Technik bekannten Nachteile nicht auftreten. As indicated in Figure 2, the end portions of the sub-plates each have connecting elements with which the sub-plates are interconnected. In this case, the connecting elements of the partial plates can be connected, for example, with bolts. Thus, for the first time by the present invention, a continuous press with Abrollplatten consisting of a plurality of sub-plates provided in which the sub-plates are connected to each other in such a way that the disadvantages known in the art do not occur.
