Description

Die Erfindung betrifft ein Verfahren nach dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung gemäß dem Oberbegriff des Anspruchs 5.The invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 5.

Eine solche Vorrichtung und ein solches Verfahren ist beschrieben in der DE-PS 31 24 688. Dort ist generell ein Verfahren und eine Vorrichtung zum Trocknen von band- oder blattförmigen fotografischen Schichtträgern beschrieben. Bei dem dort beschriebenen Verfahren kann die von den Heizelementen abgegebene Wärmestrahlung je nach dem zu trocknenden Material variiert werden. Beim Trocknen von fotografischen Schichtträgern, bei denen auf einem Schichtträger große Unterschiede im Schwärzungsgrad auftreten, läßt sich beim Stand der Technik keine optimale Intensität der Wärmestrahlung voreinstellen, denn wenig belichtete Stellen sind hell und absorbieren die Wärme in geringerem Maße als die stark belichteten und somit dunklen Bereiche des fotografischen Schichtträgers. Bei einer Einstellung der Intensität auf einen festen Wert besteht die Gefahr, daß entweder die hellen Stellen nicht ausreichend getrocknet, oder aber die dunklen Stellen durch Überhitzung beschädigt werden.Such an apparatus and such a method is described in DE-PS 31 24 688. There is generally described a method and an apparatus for drying tape or sheet-shaped photographic supports. In the method described there, the heat radiation emitted by the heating elements can be varied depending on the material to be dried. When drying photographic substrates in which there are large differences in the degree of blackening on one substrate, it is possible in the prior art do not preset an optimal intensity of the heat radiation, because areas that are not exposed to light are bright and absorb the heat to a lesser extent than the strongly exposed and thus dark areas of the photographic support. If the intensity is set to a fixed value, there is a risk that either the bright areas will not dry sufficiently or the dark areas will be damaged by overheating.

Aufgabe der Erfindung ist es deshalb, ein Verfahren anzugeben und eine Vorrichtung zur Durchführung des Verfahrens zu schaffen, womit trotz partiell unterschiedlicher Wärmeabsorption des fotografischen Schichtträgers eine gleichmäßige und filmschonende Trocknung zu erzielen ist.The object of the invention is therefore to specify a method and to provide an apparatus for carrying out the method, with which uniform and film-gentle drying can be achieved despite partially different heat absorption of the photographic support.

Die Aufgabe wird gelost durch die kennzeichnenden Merkmale des Verfahrensanspruchs 1 und durch die kennzeichnenden Merkmale des Vorrichtungsanspruchs 5.The object is achieved by the characterizing features of method claim 1 and by the characterizing features of device claim 5.

Die Erfindung macht sich dabei die Erkenntnis zu eigen, daß eine Wärmestrahlung deren Intensität automatisch entsprechend des Absorptionsgrades des Schichtträgers reguliert wird, vermeidet, daß der Schichtträger entweder nicht ganz getrocknet oder durch überhitzung beschädigt wird. Dazu ist ein Meßsensor vorgesehen, der den Absorptionsgrad des fotografischen Schichtträgers an der Stelle mißt, die der Wärmestrahlung ausgesetzt ist.The invention adopts the knowledge that heat radiation, the intensity of which is automatically regulated in accordance with the degree of absorption of the substrate, avoids that the substrate is either not completely dried or damaged by overheating. For this purpose, a measuring sensor is provided which measures the degree of absorption of the photographic support at the point which is exposed to the thermal radiation.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention result from the subclaims.

Ein mögliches Ausführungsbeispiel der Erfindung wird anhand von einer Figur näher erläutert.A possible embodiment of the invention is explained in more detail with reference to a figure.

Die Figur zeigt einen Film 1, der durch eine nicht näher gezeigte Transportvorrichtung in Richtung des Pfeiles T transportiert wird. Der Film durchläuft dabei eine Trockenvorrichtung. In dieser Trockenvorrichtung sind mehrere Heizelemente 2 angeordnet. Ein Spiegel 3 konzentriert die von den Heizelementen 2 abgegebene Wärmestrahlung auf dem Film 1. Im Material des Spiegels 3 sind Fenster 4 vorhanden, hinter denen Meßelemente 5 angeordnet sind. Jedes Meßelement erfaßt einen Bereich 6 auf dem Film 1 und mißt die den Film durchdringende Wärmestrahlung.The figure shows a film 1, which is transported in the direction of arrow T by a transport device, not shown. The film passes through a drying device. Several heating elements 2 are arranged in this drying device. A mirror 3 concentrates the heat radiation emitted by the heating elements 2 on the film 1. Windows 4 are present in the material of the mirror 3, behind which measuring elements 5 are arranged. Each measuring element detects an area 6 on the film 1 and measures the thermal radiation penetrating the film.

Auf der den Meßelementen 5 gegenüberliegenden Seite des Films 1 befindet sich ein Referenzsensor 7, welcher die von den Heizelementen 2 abgegebene Wärmestrahlung direkt mißt.On the side of the film 1 opposite the measuring elements 5 there is a reference sensor 7 which directly measures the heat radiation emitted by the heating elements 2.

Anhand der vom Meßelement 5 und vom Referenzsensor 7 gelieferten Signale läßt sich die Iransmission des Films 1 im Bereich 6 bestimmen. Mit mehreren Meßelementen 5, welche jeweils die Transmission des Films 1 an unterschiedlichen Stellen messen, läßt sich ein Mittelwert der Transmission für den Bereich des Films 1 errechnen, welcher sich gerade in der Trockenvorrichtung befindet. Die Transmission ist ein Maß für den Absorptionsgrad der Wärmestrahlung im Schichtträger. Bei hoher Transmission ist der Absorptionsgrad gering, bei niedriger Transmission hingegen hoch. Durch eine Steuereinrichtung 8 erfolgt ein automatisches Einstellen der von den Heizelementen 2 abgegebenen WärmestrahlungsintensitätThe transmission of the film 1 in the region 6 can be determined on the basis of the signals supplied by the measuring element 5 and by the reference sensor 7. With several measuring elements 5, each measuring the transmission of the film 1 at different points, an average value of the transmission can be calculated for the area of the film 1 which is currently in the drying device. The transmission is a measure of the degree of absorption of the thermal radiation in the substrate. At high The degree of absorption is low, but high for low transmission. A control device 8 automatically adjusts the heat radiation intensity emitted by the heating elements 2

Durch den Weitertransport des Films 1 in Richtung des Pfeiles T gelangt ein anderer Teil des Films 1 in die Trockeneinrichtung. Die in diesem Teil des Films vorhandene Transmission wird dabei sofort von den Meßelementen 5 erfaßt. Aufgrund der neuen Meßwerte erfolgt, falls erforderlich, sofort eine Änderung der von den Heizelementen 2 abgegebenen Wärmestrahlungsintensität. So ist gewährleistet, daß der in der Trockenvorrichtung befindliche Teil des Films 1 immer mit der richtigen Intensität bestrahlt wird, auch wenn die Transmission des Films, über die gesamte Filmfläche betrachtet, stark unterschiedlich ist.As the film 1 is transported further in the direction of the arrow T, another part of the film 1 reaches the drying device. The transmission present in this part of the film is immediately detected by the measuring elements 5. Based on the new measured values, if necessary, the heat radiation intensity emitted by the heating elements 2 is changed immediately. This ensures that the part of the film 1 located in the drying device is always irradiated with the correct intensity, even if the transmission of the film, viewed over the entire film surface, is very different.

Der Wärmeabsorptionsgrad des Films 1 kann auch anhand der vom Film 1 abgestrahlten Wärmestrahlung ermittelt werden. Bei bekannter Intensität der von den Heizelementen abgegebenen Wärmestrahlung läßt sich aus dem Meßwert für die vom Film 1 abgestrahlte Wärmestrahlung der Absorptionsgrad errechnen.The degree of heat absorption of the film 1 can also be determined on the basis of the heat radiation emitted by the film 1. If the intensity of the thermal radiation emitted by the heating elements is known, the degree of absorption can be calculated from the measured value for the thermal radiation emitted by the film 1.
