Description

451200451200

Die Erfindung betrifft eine Schleudervorrichtung zum gleichmäßigen Verteilen und Auftrocknen der lichtempfindlichen Schicht auf photographischen Platten mit elektrischen Heizvorrichtungen. Bei den bekannten Einrichtungen dieser Art sind die in Reflektoren eingebauten Heizkörper über oder unter den Platten fest angebracht. Da es schwierig ist, mit Hilfe derartiger Wärmestrahlapparate die ίο Platten auf ihrer ganzen Oberfläche gleichmäßig zu beheizen, sind nach der Erfindung die elektrisch beheizten Wärmestrahlkörper entlang der Platte bewegbar angebracht.The invention relates to a centrifugal device for uniform distribution and drying the photosensitive layer on photographic plates with electric heaters. With the known institutions of this type, the radiators built into reflectors are firmly attached above or below the panels. Since it is difficult With the help of such radiant heaters, the ίο plates are evenly distributed over their entire surface to be heated, according to the invention, the electrically heated radiant heaters along the Plate movably attached.

Hierdurch wird ein Übertracknen einzelner Stellen und die ungleichmäßige Verteilung der Schicht vermieden.This causes over-tracking of individual spots and the uneven distribution of the Shift avoided.

Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.An exemplary embodiment of the invention is shown in the drawing.

Es zeigen: Abb. 1 die Draufsicht und Abb. 2 einen Längsschnitt der Schleudervorrichtung. Das von einer Welle α getragene Armkreuz b, in das die zu schleudernden Platten d einzuspannen sind, läuft in einem Schutzmantel g um. Der Antrieb des Armkreuzes b kann von Hand oder auch mittels Elektromotors k erfolgen. Die elektrisch beheizte Wärmestrahlvorrichtung h ist an einem Arm i einstellbar angebracht, der um den Zapfen f schwingt und durch die Kurbelscheibe m dadurch über die Platte d geschwungen wird, daß ihr Kurbelzapfen η in die Schleife 0 eingreift.They show: FIG. 1 the top view and FIG. 2 a longitudinal section of the centrifugal device. The spider b carried by a shaft α , in which the slabs d to be thrown are to be clamped, runs around in a protective jacket g. The spider b can be driven by hand or by means of an electric motor k . The electrically heated radiant heat device h is adjustably attached to an arm i which swings around the pin f and is swung over the plate d by the crank disk m in that its crank pin η engages in the loop 0.

Der Antrieb der Kurbelscheibe m erfolgt von der Welle α aus durch Vermittlung des Riementriebes φ, so daß, wenn das Armkreuz b seine Umlaufbewegung ausführt, auch der Arm i entsprechend ausgeschwungen wird.The drive of the crank disk m takes place from the shaft α by means of the belt drive φ, so that when the spider b executes its orbital movement, the arm i is also swung out accordingly.

Bezüglich der Stärke der Ausschwingung des Armes i ist hervorzuheben, daß es zwar ausreichend sein wird, wenn er nur von der Mitte, d. h. von der Achse α bis zum Rand der eingespannten Platte geschwungen wird; aber damit bei geringer Schwingzahl hinsichtlich der gleichförmigen Heizung der Platte d der gleiche Erfolg zu erzielen ist, empfiehlt es sich, den Arm i nach beiden Richtungen über die volle Platte ausschwingen zu lassen.With regard to the strength of the oscillation of the arm i , it should be emphasized that it will be sufficient if it is only swung from the center, ie from the axis α to the edge of the clamped plate; but so that the same result can be achieved with regard to the uniform heating of the plate d with a low frequency of oscillation, it is advisable to let the arm i swing out in both directions over the full plate.

Der Arm i kann auch mit mehreren Heizvorrichtungen versehen werden, und es ist auch angängig, ihn im inneren Teil, d. h. am Boden des Gehäuses g anzubringen.The arm i can also be provided with several heating devices, and it is also possible to mount it in the inner part, ie on the bottom of the housing g .

An Stelle der schwingbaren Bewegung der Heizapparate h kann, auch eine geradlinige Bewegung gewählt werden, etwa in der Weise, daß sie in einer diametral angebrachten Führung sich verschieben.Instead of the oscillating movement of the heating devices h , a linear movement can also be selected, for example in such a way that they move in a diametrically attached guide.
