Description
Vorrichtung zum Trocknen und Hochglänzendmachen von Photokopien Es sind Vorrichtungen zum Trocknen und Hochglänzendmachen von Photokopien bekanntgeworden, bei denen heizbare Trockentrommeln o. dgl. benutzt werden. Die Wärmeübertragung auf die Trockenflächen erfolgt hier durch Gas, Elektrizität, Wasserdampf o. dgl.Apparatus for drying and glossing photocopies Es devices for drying and making photocopies glossy have become known, where heatable drying drums or the like are used. The heat transfer on the dry areas is carried out here by gas, electricity, steam or the like.
Die Hauptforderung für das Trocknen und die Hochglanzerzeugung bei diesen Maschinen ist aber gleichbleibende Temperatur während des Arbeitsvorganges. Diese Forderung wird von den bekannten Einrichtungen nicht befriedigend erfüllt, obgleich auch hier eine Regelung der Temperatur vorgesehen ist. Denn die Wärme, durch Gas oder Elektrizität erzeugt, wird durch die Luft auf die Trocken-oder Hochglanzfläche übertragen. Hierbei ist es natürlich nicht möglich, die Abkühlung durch die Verdunstungskälte auszugleichen. Auch selbsttätige Regler können diesen örtlichen Abkühlungen nicht folgen. Kommt z. B. während des Arbeitens das zu trocknende Material teilweise auf einen vorbenutzten, abgekühlten Teil der Trockenoberfläche und teilweise auf einen nicht vorbenutzten Teil zu liegen, so wird die Trocknung unausgeglichen erfolgen. Auch bei der Wärmeübertragung durch Dampf ist eine ausreichende Abstimmung der Temperatur schwierig.The main requirement for drying and producing a high gloss These machines, however, have a constant temperature during the work process. This requirement is not met satisfactorily by the known institutions, although a regulation of the temperature is also provided here. Because the warmth Generated by gas or electricity, air is applied to the dry or glossy surface transfer. Here it is of course not possible to use the evaporative cooling balance. Even automatic regulators cannot deal with this local cooling follow. Comes z. B. while working on the material to be dried partially a previously used, cooled part of the drying surface and partially on one If the part is not previously used, the drying will be unbalanced. Even when heat is transferred by steam, the temperature must be adequately coordinated difficult.
Nach der Erfindung wird ein praktisch vollkommener Wärmeausgleich dadurch erzielt, daß man die Wärme mittels einer Flüssigkeit überträgt. Wird beispielsweise die Trockentrommel oder der Trockenkörper mit Wasser, Glycerin oder einem beliebigen anderen flüssigen Wärmeübertrager gefüllt, so erfolgt während der Abkühlung durch den Trockenprozeß eine intensive Nachheizung, welche den Trockenprozeß außerordentlich beschleunigt und vor allem kontrollierbar gestaltet. Um das Gewicht der betriebsfertigen Vorrichtung herabzusetzen, kann man auch doppelwandige Zylinder wählen, bei welchen sich die Heizflüssigkeit zwischen den Wandungen befindet.According to the invention, a practically perfect heat balance is achieved achieved by transferring the heat by means of a liquid. For example the drying drum or drying body with water, glycerin or any other filled with another liquid heat exchanger, it takes place during cooling through the drying process an intensive after-heating, which makes the drying process extraordinary accelerated and, above all, designed to be controllable. To the weight of the ready to use Reduce device, you can also choose double-walled cylinders, which the heating fluid is between the walls.
