Description

Durchlaufentwicklungsgerät für fotografische Schichtträger Die Erfindung betrifft ein Durchlaufentwicklungsgerät für fotografische Schichtträger mit gelochten Gleitbahnen zur Führung der Schichtträger durch die Behandlungsflüssigkeit.Continuous processing apparatus for photographic supports. The invention relates to a continuous processor for photographic support with perforated Slideways for guiding the substrate through the treatment liquid.

Bei den bekannten Vorrichtungen dieser Art besteht die Schwierigkeit, die fotografischen Schichtträger, insbesondere Papiere, faltenfrei und ohne Hemmungen durch das Bad bzw. die Bäder zu fördern. Die Schichtträger werden auf ihrem Wege durchfeuchtet und verlieren häufig ihre für die Führung notwendige Steifheit. Sie bleiben dann an den gekrümmten Flächen der Führungskanäle leicht haften. Es kommt dann zur Falten- und Schleifenbildung der Schichtträger.With the known devices of this type there is the difficulty the photographic substrates, especially papers, without creases and without inhibitions to promote through the bath or the baths. The layers are on their way soaked through and often lose their stiffness necessary for guidance. she then easily adhere to the curved surfaces of the guide channels. It is coming then to the formation of wrinkles and loops in the substrate.

Die Erfindung besteht darin, daß die Gleitbahnen quer zur Laufrichtung der Schichtträger beweglich gelagert sind und während des Durchlaufs der Schichtträger durch Nockenscheiben od. dgl. auf und ab bewegt werden.The invention consists in that the slideways transverse to the direction of travel the support are movably mounted and during the passage of the support be moved up and down by cams or the like.

Der Vorteil der Erfindung besteht darin, daß bei der Bewegung der Gleitbahnen die Badflüssigkeit durch die Durchbrechungen der Gleitbahnen hindurchgedrückt wird und die Schichtträger von den Gleitbahnwandungen abhebt, so daß ein Haften der Schichtträger an den Gleitbahnen vermieden wird. Auf diese Weise werden die den bekannten Konstruktionen anhaftenden Nachteile, die durch das Hängenbleiben der Schichtträger an den Gleitbahnen hervorgerufen werden, vermieden.The advantage of the invention is that when moving the Slideways the bath liquid is pushed through the openings in the slideways is and the layer carrier lifts off the slideway walls, so that an adhesion the layer support on the slideways is avoided. In this way, the the known constructions inherent disadvantages caused by the sticking caused by the layer carrier on the slideways, avoided.

In der Zeichnung ist die Erfindung beispielsweise und schematisch in einem Längsschnitt dargestellt. Das Durchlaufentwicklungsgerät besteht aus zwei Trögen 1 und 2, an deren Enden die Förderwalzenpaare 3, 4, 5 und 6 angeordnet sind.In the drawing, the invention is exemplified and schematic shown in a longitudinal section. The continuous processor consists of two Troughs 1 and 2, at the ends of which the pairs of conveyor rollers 3, 4, 5 and 6 are arranged.

Ein Umlenkbogen 7 dient zur Umlenkung der Schichtträger von einem Trog in den anderen. In den Trögen ist je ein Führungskanal 8, 9 so angeordnet, daß sein wesentlicher Teil unter dem Flüssigkeitsspiegel der Badflüssigkeit liegt. Die die Gleitbahnen bildenden Wandungen 10, 11, 13, 14 der Führungskanäle 8 und 9 sind mit Durchbrechungen 12 und 15 versehen.A deflection sheet 7 is used to deflect the layer carrier from one Trough in the other. A guide channel 8, 9 is arranged in each of the troughs in such a way that that its essential part is below the liquid level of the bath liquid. The walls 10, 11, 13, 14 of the guide channels 8 and forming the slideways 9 are provided with openings 12 and 15.

An den Schwenkachsen 16, 17 sind die Führungskanäle beweglich aufgehängt und ruhen auf Anschlägen 20, 21. Jedem Führungskanal ist eine gezahnte Nockenscheibe 18 bzw. 19 zugeordnet, in deren Bereich er mit einem Ende hineinragt. Werden die Nocken gedreht, so heben sie die Gleitbahnen an einem Ende abwechselnd an und lassen sie wieder fallen. Hierdurch wird bewirkt, daß bei jeder Bewegung Flüssigkeit durch die Löcher der Gleitbahnen hindurchtritt und die Schichtträger von der betreffenden Gleitbahn abhebt. Damit wird verhindert, daß die Schichtträger an den Gleitbahnen haftenbleiben.The guide channels are movably suspended on the pivot axes 16, 17 and rest on stops 20, 21. Each guide channel is a toothed cam disk 18 or 19 assigned, in the area of which it protrudes with one end. Will the If the cam is rotated, they alternately lift and leave the slideways at one end they fall again. This causes liquid to flow through with every movement the holes of the slideways passes through and the substrate from the relevant Slideway lifts off. This prevents the substrate from adhering to the slideways stick.
