Description

Furniertrockenpresse mit heizbaren Platten. Die Erfindung betrifft .eine Furni:ertrockenpresse mit heizbaren Platten.Veneer drying press with heatable plates. The invention relates to .a veneer: drying press with heatable plates.

Das Neue besteht darin:, daB in dem Antrieb ein Kniehebelgetrieb:e, Kurbelschleifengetriebe oder ein ähnliches Getriebe eingeschaltet ist, welches bis in die Totlage und darüber hinaus bewegbar ist.The novelty consists in the fact that in the drive a toggle lever mechanism: e, Slider crank gear or a similar gear is switched on, which up to can be moved into the dead position and beyond.

Hierdurch wird eine im Verhältnis zur Lüftungsdauer lange Berührungsdauer erzielt, ohne den KraftschluB des Plattenanr,;ebes aufzuheben. Die Heizplatten i, 3, 5, 7 usw. in Abb. z sind an den Stangen a a und die Heizplatten z, q., 6, 8 usw. an den Stangen b b in Schlitzen aufgehängt.. Die Stangen a a, b b hängen in den Hebeln c c; diese sind in dem Gestell d gelagert und werden durch die Zugstange e und den' Hebel f in schwingende Bewegung versetzt. Hierdurch nähern und entfernen sich die Heizplatten abwechselnd. An dem Hebel f greift ein Kniehebelgetriebe g h an, das durch die Schubstange 1 und Kurbelscheibe k oder durch einen anderen Antrieb aus der gezeichneten Lage I bis in die Totlage III und darüber hinaus bis in die Stellung IV gedrückt wird. Von I bis II erfolgt der Leerhub der Heizplatten. Bei II berühren die Platten r, 3, 5, 7 usw. die darüberliegenden und heben diese an bis zur Stellung III. Hierauf erfolgt ein gemeinsames Senken der Platten bis Stellung IV, ohne daß die Bexührung aufhört. Beim Rückgang des Hebels wiederholt sich der Vorgang in tongekehrter Reihenfolge.This results in a long contact time in relation to the ventilation time, without canceling the frictional connection of the panel contact. The heating plates i, 3, 5, 7 etc. in Fig. Z are suspended from the rods a a and the heating plates z, q., 6, 8 etc. are suspended from the rods bb in slots. The rods aa, bb are suspended in the levers cc; these are stored in the frame d and are set in oscillating motion by the pull rod e and the lever f. As a result, the heating plates alternately approach and retreat. A toggle mechanism gh engages the lever f and is pressed by the push rod 1 and crank disk k or by another drive from the position I shown to the dead position III and beyond to the position IV. The idle stroke of the heating plates takes place from I to II. At II the plates r, 3, 5, 7 etc. touch the overlying ones and lift them up to position III. This is followed by a common lowering of the plates to position IV, without the loading ceases. When the lever is released, the process is repeated in reverse order.

Durch diese Anordnung wird erzielt, daß während eines Drittels des Weges des Hebels, nämlich von I bis 1I, der Leerhub der Platten erfolgt, während die Berührung von II bis IV also auf zwei Drittel dies Weges andauert. Ferner ist der Anhub m n der sich berührenden Platten nur ein kleiner Teil (27 Prozent) des Gesamthubes 1.n der Platten.By this arrangement it is achieved that during a third of the way of the lever, namely from I to 1I, the idle stroke of the plates takes place, while the contact from II to IV lasts for two thirds of this way. Furthermore, the stroke mn of the plates in contact is only a small part (27 percent) of the total stroke 1.n of the plates.

Ein. weiterer Vorteil der Anordnung besteht darin, daß die Übersetzung des Kniehebelgetriebes g h sich von Stellung 1 bis III steigert. Während des Leerhubes der Platten (Stellung i bis II) sind dieselben im Gleichgewicht, der Kraftbedarf ist also gering, und dementsprechend ist auch die übersetzung des Kniehebelgetriebes klein. Beim Anhub der Platten (Stellung II bis III) wird der Kraftbedarf groß. In dieser Stellung hat sich aber jauch die Übersetzung des Kniehebelgetriebes erheblich gesteigert. An Stelle des Kniehebelgetriebes ig h kann auch ein Kurbelschleifengetriebe o p (Abb. 2) verwendet werden, welches von Stellung 1 bis in die Totlage III, wie gezeichnet, und darüber hinaus in Stellung IV gedrückt wird und dadurch die gleiche Bewegung der Platten, wie vorher, erzielt.A. Another advantage of the arrangement is that the translation of the toggle mechanism g h increases from position 1 to III. During the idle stroke of the plates (position i to II) are the same in equilibrium, the power requirement is therefore low, and the gear ratio of the toggle lever mechanism is accordingly small. When the plates are lifted (position II to III), the power requirement is great. In but this position has significantly increased the translation of the toggle mechanism increased. Instead of the toggle mechanism ig h, a slider crank mechanism can also be used o p (Fig. 2) can be used, which is from position 1 to dead center III, such as drawn, and is also pressed into position IV and thereby the same Movement of the plates, as before, is achieved.

Auch Scheiben mit Krümmungen und andere Getriebe, welche die Hubbewegung verzögern. und die Übersetzung steigern, können für den gleichen Zweck verwendet werden.Also discs with curvatures and other gears, which the lifting movement delay. and increase translation can be used for the same purpose will.
