Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Aufbringen einer Flächenpressung auf fortschreitende Werkstücke, wie Holzwerkstoffplatten o.dgl., bei der mindestens ein umlaufendes Preßband an das Werkstück von einem in eine Druckkammer einleitbaren Druckmittel anpreßbar und die Druckkammer durch einen Teil eines Arbeitstrums des Preßbandes, an der dem Arbeitstrum gegenüberliegenden Seite durch eine rechteckförmige Druckplatte und an den in bezug auf die Laufrichtung des Preßbandes Längs- und Querrändern der Druckplatte durch eine am Rand der Druckplatte vorgesehene, sich am Preßband abstützende Dichtung begrenzt ist.The invention relates to a device for applying surface pressure to progressive workpieces, such as wood-based panels or the like, in which at least one rotating press belt can be pressed against the workpiece by a pressure medium that can be introduced into a pressure chamber, and the pressure chamber can be pressed through part of a working strand of the press belt. on the side opposite to the working area by a rectangular pressure plate and on the longitudinal and transverse edges of the pressure plate with respect to the running direction of the press belt by a seal provided on the edge of the pressure plate and supported on the press belt.

Eine derartige Vorrichtung ist aus der EP-A2-0 087 651 bekannt.Such a device is known from EP-A2-0 087 651.

Zwar hat sich die dort beschriebene Vorrichtung bewährt, jedoch sind hinsichtlich der Fertigung und der Montage bzw. Demontage beim Auswechseln der Dichtung kostensenkende Maßnahmen wünschenswert, die nicht nur die Herstellung sondern auch den Betrieb einer derartigen Vorrichtung wirtschaftlicher erscheinen läßt.Although the device described there has proven itself, with regard to the manufacture and assembly or disassembly when replacing the seal, cost-reducing measures are desirable, which not only make the production but also the operation of such a device appear more economical.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der gattungsgemäßen Art so zu gestalten, daß die Halterung der sich am Arbeitstrum abstützenden Dichtung an der Druckplatte vereinfacht wird. Diese Aufgabe wird erfindungsgemäß durch die im kennzeichnenden Teil des Anspruchs 1 genannten Maßnahmen gelöst.The invention is therefore based on the object of designing a device of the generic type in such a way that the mounting of the seal which is supported on the working strand on the pressure plate is simplified. This object is achieved by the measures mentioned in the characterizing part of claim 1.

Durch eine Druckbeaufschlagung des Innenraumes des Schlauches mit einem Druckmittel wird der Schlauch in der zugeordneten Nut der Druckplatte form- und kraftschlüssig festgelegt. Durch den durch das Druckmittel erzeugten Innendruck des Schlauches und durch die elastische Verformbarkeit des Schlauchmaterials wird die durch einen Teilbereich des Schlauches gebildete Dichtungsleiste oder die am Schlauch zusätzlich festgelegte Dichtungsleiste an das Arbeitsrum des Preßbandes gedrückt.By pressurizing the interior of the hose with a pressure medium, the hose is positively and non-positively fixed in the assigned groove of the pressure plate. Due to the internal pressure of the hose generated by the pressure medium and the elastic deformability of the hose material, the sealing strip formed by a partial region of the hose or the sealing strip additionally fixed on the hose is pressed against the working area of the press belt.

Ein weiterer erheblicher Vorteil der Erfindung liegt darin, daß sowohl die Montage als auch die Demontage der gesamten Dichtung wesentlich vereinfacht wird, was sich einerseits positiv auf die Fertigungskosten und andererseits positiv auf Wartungskosten auswirkt.Another significant advantage of the invention is that both the assembly and the disassembly of the entire seal is significantly simplified, which has a positive effect on the manufacturing costs and positive maintenance costs.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen und der folgenden Beschreibung von in den Zeichnungen dargestellten Ausführungsbeispielen.Further features of the invention emerge from the subclaims and the following description of exemplary embodiments illustrated in the drawings.

Die Preßbänder 4 umlaufen Umlenkrollen 5 und werden von diesen angetrieben. Sie sind mit einem Spalt zueinander angeordnet, der der Breite eines zu bearbeitenden Werkstückes 6 entspricht. Während die Preßbänder 4 mit ihren das Werkstück 6 berührenden Oberflächen eine waagerecht Bewegung ausführen, wird das Werkstück 6 in die Vorrichtung, und zwar in den Spalt, der zwischen den Oberlfächen besteht, hineingezogen und dort von den Oberflächen der Preßbänder mit Druck beaufschlagt. Beim Durchlauf des Werkstückes 6 durch die Vorrichtung erfolgt somit seine Bearbeitung, so daß es als fertig bearbeitetes Werkstück den Spalt zwischen den Preßbändern 4 verläßt.The device 1 has a lower frame 2 and an upper frame 3, in each of which endless press belts 4 are installed. The press belts 4 run around deflection rollers 5 and are driven by them. They are arranged with respect to one another with a gap which corresponds to the width of a workpiece 6 to be machined. While the press belts 4 carry out a horizontal movement with their surfaces touching the workpiece 6, the workpiece 6 is drawn into the device, specifically into the gap that exists between the surfaces, and is pressurized there by the surfaces of the press belts. When the workpiece 6 passes through the device, it is processed so that it leaves the gap between the press belts 4 as a finished workpiece.

In dem in der Fig. 2 dargestellten Ausführungsbeispiel werden auf die Ober- und Unterseite des Werkstückes 6 Folien 7 aufgepreßt, die von Vorratsrollen 8 abgezogen werden. Der Preßvorgang kann bei Raumtemperatur oder bei höheren Temperaturen erfolgen, die auf das Werkstück im Bearbeitungsbereich aufgebracht werden. Zur Erzeugung des gewünschten Druckes kann der obere Rahmen 3 insgesamt gegen den unteren Rahmen 2 gepreßt werden oder es kann nach einer Grobeinstellung des Abstandes zwischen dem oberen Rahmen 3 und dem unteren Rahmen 2 der erforderliche Druck mittels eines Luftdruckes ausgeübt werden, der in Druckkammern 9 aufgebaut wird, die jeweils an der Rückseite des Preßbandes 4 in bezug auf das Werkstück 6 angeordnet sind.In the exemplary embodiment shown in FIG. 2, foils 7 are pressed onto the top and bottom of the workpiece 6 and are pulled off from supply rolls 8.

The hose 19 can be made of plastic or rubber. The sealing strip 20 differs in consistency from the rest of the hose material and consists of an abrasion-resistant plastic or rubber.

In Abwandlung der in der Fig. 4 aufgezeigten Konstruktion kann die Dichtungsleiste 21 auch aus dem gleichen Material wie der übrige Schlauch 22 gefertigt sein. In der in der Fig. 5 aufgezeigten Ausführungsform ist die Dichtungsleiste 21 mit einer Außenschicht 23 aus Metall oder Keramik versehen. Durch diese Außenschicht wird eine hohe Abriebfestigkeit der Dichtungsleiste erzielt.In a modification of the construction shown in FIG. 4, the sealing strip 21 can also be made of the same material as the rest of the hose 22. In the embodiment shown in FIG. 5, the sealing strip 21 is provided with an outer layer 23 made of metal or ceramic. A high abrasion resistance of the sealing strip is achieved through this outer layer.

Bei dem Ausführungsbeispiel nach der Fig. 6 ist die Dichtungsleiste 24 in einer Nut einer Außenprofilschiene 25 verankert, die mit einer in dem im Schlauch 26 vorgesehenen Innenschiene 27 verbunden ist.
