Description
Die Erfindung betrifft eine kontinuierlich arbeitende Presse, vorzugsweise zum Herstellen und/oder Beschichten von Spanplatten, Faserplatten oder dgl. Pressgut, mit einer unteren und einer oberen Pressplatte, einem um die untere Pressplatte und einem um die obere Pressplatte geführten endlosen Pressband und einer Anordnung zum Aufbau und Aufrechterhaltung eines Schmiermittelfilmes zwischen den einander zugewandten Pressplattenflächen und den jeweils zugehörigen Pressbändern, wobei die Presse über die Arbeitslänge einen eingangsseitigen Pressenhochdruckbereich, einen Pressenmitteldruckbereich und einen ausgangsseitigen Pressenniederdruckbereich aufweist.The invention relates to a continuously operating press, preferably for the production and / or coating of chipboard, fiberboard or The like. Pressgut, with a lower and an upper press plate, one around lower press plate and an endless one guided around the upper press plate Press belt and an arrangement for building and maintaining a Lubricant film between the facing press plate surfaces and the associated press belts, the press over the working length a high-pressure area on the input side, a Press medium pressure area and an outlet-side press low pressure area having.
Kontinuierlich arbeitende Pressen der gattungsgemäßen Art sind prinzipiell aus dem Stand der Technik bekannt. So ist beispielsweise in der EP 01 28 968 eine als Hydrodynpresse bezeichnete Presse offenbart, die sich in der Praxis bereits vielfach bewährt hat. Sie ermöglichst nicht nur die Herstellung unterschiedlichster plattenförmiger Produkte im kontinuierlichen Betrieb, sondern zeichnet sich auch durch Wirtschaftlichkeit, gleichzeitig hohe Genauigkeiten und die Möglichkeit, ein Eingangsbeschichtungsverfahren mit Duroplastfilmen durchzuführen, aus. Die prinzipielle Arbeitsweise der in der oben angeführten Patentschrift offenbarten kontinuierlich arbeitenden Presse sieht vor, dass über die Länge des gesamten Pressbereiches der Presse gesehen der Pressdruck im Einlaufbereich steil auf einen Maximalwert von beispielsweise 25 bar ansteigt, um anschließend in einem Mitteldruckbereich parabelförmig abzusinken und abschließend in einem Niederdruckbereich auf einem Niveau von beispielsweise 5 bar gehalten zu werden. Darüber hinaus findet im ersten Drittel der Gesamtpresslänge die größte Erwärmung des Pressgutes auf eine Reaktionstemperatur des im Pressgut enthaltenen Bindemittels von beispielsweise 180° Celsius oder höher statt.Continuously operating presses of the generic type are in principle known from the prior art. For example, EP 01 28 968 discloses a press known as a hydrodynamic press, which can be found in the Practice has already proven itself many times. It not only enables production various plate-shaped products in continuous operation, but is also characterized by economy, high at the same time Accuracies and the possibility of using an input coating process To perform thermoset films. The principle of operation in the the above-mentioned patent disclosed continuous press stipulates that the length of the entire press area of the press seen the pressure in the inlet area steeply to a maximum value of for example, increases 25 bar, then in a medium pressure range descend parabolically and finally up in a low pressure area to be kept at a level of, for example, 5 bar. Furthermore finds the greatest warming of the in the first third of the total press length Pressed material to a reaction temperature of that contained in the pressed material Binder of, for example, 180 ° Celsius or higher instead.
Somit wird in dem einlaufseitig ca. ersten Drittel der Presse der größte Druck auf das Pressgut ausgeübt und die größte Wärmemenge in das Pressgut übertragen. Der bei herkömmlichen aus dem Stand der Technik bekannten kontinuierlichen Pressen verwendete isobare Schmiermittelfilm mit einer Dicke von 0,3 bis 0,5 mm zwischen den Pressbändem und den zugehörigen oberen und unteren Pressplatten hat somit insbesondere im Hochdruckbereich der Presse eine doppelte Aufgabenstellung zu erfüllen. Die Übertragung hoher Pressdrücke in Verbindung mit einer großen Wärmedurchleitung durch den Schmiermittelfilm macht bei herkömmlichen Pressen ein hohes Maß an Energieaufwand erforderlich, Darüber hinaus erhöhen die zu erfüllenden Rahmenbedingungen an Wärmeleitfähigkeit und Pressdruckübertragung den Verschleiß des verwendeten Pressöls.Thus, the greatest pressure is in the first third of the press on the inlet side exerted on the pressed material and the greatest amount of heat in the pressed material transfer. The conventional one known from the prior art Isobaric lubricant film with a continuous press used Thickness of 0.3 to 0.5 mm between the press belts and the associated ones upper and lower press plates thus has particularly in the high pressure area to fulfill a double task for the press. The transfer high pressures in connection with a large heat transfer through the lubricant film makes a high on conventional presses Amount of energy required, in addition, increase those to be met Framework conditions for thermal conductivity and pressure transfer the wear of the press oil used.
Aufgabe der vorliegenden Erfindung ist es daher, eine kontinuierlich arbeitende Presse der gattungsgemäßen Art so weiterzuentwickeln, dass der Energieeinsatz und die Betriebskosten beim Betrieb derartiger Pressen herabgesetzt und die Standzeiten der Öle der Pressen heraufgesetzt werden.The object of the present invention is therefore a continuously working Develop the press of the generic type so that the Use of energy and operating costs when operating such presses reduced and the service life of the oils of the presses increased become.
Diese Aufgabe wird in Zusammenschau mit den gattungsbildenden Merkmalen
durch die technische Lehre des kennzeichnenden Teils des Anspruches
1 gelöst.This task is viewed in conjunction with the generic characteristics
through the technical teaching of the characterizing part of the
Die Lösung besteht wesentlich darin, dass im presseneingangsseitigen Bereich über die gesamte Breite und im Wesentlichen die Länge des Pressenhochdruckbereiches zwischen den Pressplatten und dem jeweiligen zugehörigen Pressband ein Rollenteppich angeordnet ist. The main solution is that in the press entrance Area across the full width and essentially the length of the Press high pressure area between the press plates and the respective associated press belt a roller carpet is arranged.
Der Durchmesser der Rollen sollte möglichst klein gewählt werden (zum
Beispiel im Bereich 12 mm bis 20 mm), um eine gleichmäßige Druckbeaufschlagung
auf die Stahlbänder und damit auf das Pressgut zu gewährleisten,
da kleinere Rollen den Abstand der aufeinander folgenden Rollenreihen
verfleinem und eine fast gleichmäßige Druckbeaufschlagung ergeben. Die
Folge der gleichmäßigen Druckbeaufschlagung ist eine bessere Oberflächengüte
und eine längere Lebensdauer der Stahlpressbänder.The diameter of the rollers should be as small as possible (for
Example in the
Durch diese erfindungsgemäße Gestaltung werden gerade in dem Pressenbereich, in dem herkömmlich durch die Verwendung eines Schmiermittelfilmes von 0,3 mm bis 0,5 mm zwischen Pressband und Pressplatte ein besonders hoher Energieaufwand notwendig ist, nunmehr mechanisch durch den Rollenteppich sowohl der Pressdruck als auch die Wärme von der Pressplatte auf das Pressband und somit das Pressgut übertragen. Es sind somit keinerlei Hochdruckpumpen für die Bereitstellung des Schmiermittelfilmes notwendig, wodurch auch unabhängig von dem zu übertragenden Druck keinerlei Energieaufwand zum Aufrechterhalten des Druckes benötigt wird. Darüber hinaus weist der Rollenteppich gegenüber dem Stand der Technik eine bessere Wärmeleitfähigkeit von ca. 440 W/(m * k) auf, wohingegen für die im Stand der Technik verwendeten Ölschmiermittel nur Wärmeleitfähigkeiten bis maximal 370 W/(m * k) angegeben werden können.With this design according to the invention, especially in the press area, in the conventional way through the use of a lubricant film from 0.3 mm to 0.5 mm between the press belt and press plate particularly high energy consumption is now necessary mechanically the roller carpet both the pressing pressure and the heat from the Transfer the press plate to the press belt and thus the material to be pressed. There are therefore no high pressure pumps for the provision of the lubricant film necessary, which makes it independent of the one to be transmitted Pressure does not require any energy to maintain the pressure becomes. In addition, the roller carpet faces the state of the Technology has a better thermal conductivity of approx. 440 W / (m * k), whereas for the oil lubricants used in the prior art only Thermal conductivities up to a maximum of 370 W / (m * k) can be specified.
Weitere vorteilhafte Ausgestaltungen des Gegenstandes der Erfindung ergeben sich aus den Merkmalen der Unteransprüche.Further advantageous configurations of the subject matter of the invention result derive from the features of the subclaims.
Je nach zu pressendem Material und daraus resultierenden Presskurven während des Durchlaufes des Pressgutes durch die kontinuierlich arbeitende Presse kann es vorteilhaft sein, wenn der Rollenteppich in seiner Längenausdehnung in Arbeitsrichtung der Presse gesehen, zusätzlich mindestens in einem Teilbereich des dem Hochdruckbereich zugewandten Abschnittes des Mitteldruckbereiches angeordnet ist. Da in diesem Teilbereich des Mitteldruckbereiches noch relativ hohe Druckwerte anzusetzen sind, ermöglicht die Ausdehnung des Rollenteppiches in diesem Bereich eine zusätzliche Energieeinsparung während des Pressenbetriebes.Depending on the material to be pressed and the resulting pressing curves during the passage of the pressed material through the continuously working It can be advantageous if the roller carpet in its press Length extension seen in the working direction of the press, in addition at least in a part of the area facing the high pressure area Section of the medium pressure range is arranged. Because in this area relatively high pressure values in the medium pressure range expansion of the roller carpet in this area enables one additional energy savings during press operation.
An den Rollenteppich schließt sich dann unmittelbar die Anordnung zum Aufbau und der Aufrechterhaltung des Schmiermittelfilmes zwischen den einander zugewandten Pressplattenflächen und den jeweils zugehörigen Pressbändem an. In diesen Bereichen der Presse, der u. a. als Kalibrierbereich für das Pressgut dient, sinkt der Innendruck im Pressgut mit der Aushärtung des Bindemittels gegen Null, wobei die Temperatur im Pressgut durch die Presse aufrecht gehalten bzw. im Kalibrierbereich gesenkt wird, um das Pressgut zu kühlen.The arrangement for the roller carpet then immediately follows Structure and maintenance of the lubricant film between the mutually facing press plate surfaces and the associated Press belts. In these areas of the press, the u. a. as a calibration area serves for the material to be pressed, the internal pressure in the material to be pressed decreases with the Hardening of the binder towards zero, the temperature in the material to be pressed held upright by the press or lowered in the calibration range in order to to cool the material to be pressed.
In diesem Bereich lässt sich ein Vorteil des zwischen Pressplatte und Pressband befindlichen Schmiermittelfilms nutzen, der darin besteht, dass die Temperatur durch das umlaufende Öl direkter und schneller gesteuert werden kann als mit dem im vorderen Bereich befindlichen Rollenteppich. Somit kann die Aushärtung und Kalibrierung des Pressgutes, welches den Bereich des Rollenteppichs verlassen hat, dort erwärmt und verdichtet worden ist, im hinteren Bereich der kontinuierlich arbeitenden Presse durch den hier Verwendung findenden Schmiermittelfilm feinfühlig gesteuert werden, so dass evtl. vorhandene durch den Rollenteppich hervorgerufene Unebenheiten problemlos egalisiert werden können.In this area there is an advantage between the press plate and press belt use existing lubricant film, which consists in that the Temperature is controlled more quickly and directly by the circulating oil can be as with the roller carpet located in the front area. Thus, the curing and calibration of the pressed material, which the Has left the area of the roller carpet, warmed there and compressed has been in the back of the continuously working press controlled the lubricant film used here with great care so that any existing ones caused by the roller carpet Unevenness can be leveled out easily.
Da im Niederdruckbereich das Öl nicht so hoch belastet wird, steigt die Standzeit. Da weiterhin die zu übertragende Wärmemenge gering ist, wird zur Wärmeübertragung keine große Menge Öl benötigt.Since the oil is not so heavily loaded in the low pressure range, it increases Life. As the amount of heat to be transferred is still small, no large amount of oil required for heat transfer.
Somit lässt sich durch die erfindungsgemäße Gestaltung der kontinuierlich arbeitenden Presse sowohl eine wesentliche Energieeinsparung im Pressenbetrieb erreichen sowie eine Verringerung der Fertigungstoleranzen auf bis zu +/- 6/100 mm erreichen als auch die Möglichkeit, das Eingangsdirektbeschichtungsverfahren mit Duroplastfilmen durchzuführen Thus, the design according to the invention enables the working press both a significant energy saving in the Achieve press operation and a reduction in manufacturing tolerances up to +/- 6/100 mm as well as the possibility of the input direct coating process perform with thermoset films
