Description
Vorrichtung zum Fördern, Zusammenpressen oder Abquetschen insbesondere von fotografischen Aufzeichnungsträgern Device for conveying, compressing or squeezing off, in particular photographic recording media
Die Erfindung betrifft eine Vorrichtung zum Fördern, Zusammenpressen oder Abquetschen insbesondere von fotografischen Aufzeichnungsträgern mit wenigstens einem Walzenpaar. The invention relates to a device for conveying, compressing or squeezing, in particular photographic ones Recording media with at least one pair of rollers.
Bei bekannten Vorrichtungen der genannten Art werden zum federnden Aneinanderhalten der Walzen Federn oder Haltemittel aus Stahl verwendet. Gewöhnlicher Federdraht ist wegen der durch die aggressiven Bearbeitungsflüssigkeiten für die fotografischen Aufzeichnungsträger bedingten Korrosionsgefahr nicht zu verwenden. Die deshalb bisher verwendeten Federn aus hochlegiertem Edelstahl haben schlechtere Federeigenschaften, die überdies um bis zu 20% bei jeder Feder streuen können. Ausserdem ist der bisher verwendete Edelstahl schwierig zu verarbeiten und verhältnismässig kostspielig.In known devices of the type mentioned, springs or holding means are used for resiliently holding the rollers together made of steel used. Ordinary spring wire is because of the aggressive machining fluids conditional for the photographic recording media Do not use risk of corrosion. That's why so far The springs made of high-alloy stainless steel used have poorer spring properties, which moreover by up to Can spread 20% with each spring. In addition, the high-grade steel used up to now is difficult to process and proportionate expensive.

Bei herkömmlichen Federn ist es ferner möglich, dass sie beim Auseinandernehmen der Vorrichtungen zum Zwecke der Reinigung von ihren Halterungen abspringen oder gar brechen* Schliesslich sind die herkömmlichen Lagerungen wegen der verwendeten Federn schwierig zu montieren. Es ist das Ziel der Erfindung, eine Vorrichtung der eingangs genannten Art zu schaffen, bei der die Walzen ohne die Verwendung von Stahlfedern mit den genannten Nachteilen federnd zueinander gelagert sind.With conventional springs, it is also possible that when disassembling the devices for the purpose jump off their brackets or even break after cleaning * Finally, the conventional bearings difficult to assemble because of the springs used. It is the aim of the invention to provide a device of the initially mentioned to create said type, in which the rollers without the use of steel springs with the disadvantages mentioned are resiliently mounted to each other.
Erfindungsgemäss wird dies dadurch erreicht, dass die Wellenenden der beiden Walzen jeweils in federnden Enden eines einstückigen, aus korrosionsbeständigem Kunststoff bestehenden, S-förmig ausgebildeten Lagerblockes drehbar gelagert sind.According to the invention this is achieved in that the Shaft ends of the two rollers each in resilient ends of a one-piece, made of corrosion-resistant plastic existing, S-shaped bearing block are rotatably mounted.
Zweckmässige Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen und aus der Beschreibung, worin ein Ausführungsbeispiel anhand von Figuren eingehend erläutert ist.

Durch, einen Schlitz einer ausschnittweise in Figur 2 gezeigten Seitenwand 2 eines Bearbeitungstanks für die fotografischen Aufzeichnungsträger ragen die Enden 3a und 4a von zwei Walzen 3 und 4 in den Raum ausserhalb des Bearbeitungstanks. Die Enden 3a und 4a sind in entsprechenden Bohrungen 5a und 5b eines Lagerblocks 5 gelagert, der - wie Figur 1 zu entnehmen ist - aus einer rautenförmigen Scheibe mit abgerundeten Ecken und Einschnitten 5° und 5d besteht. Die Einschnitte 5c und ^d sind dabei an ihren Enden zum besseren Ausgleich von Biegespannungen erweitert. Durch die Einschnitte 5c und 5d werden federnde Arme 5e und 5f des Lagerblocks 5 gebildet, in denen sich die Bohrungen 5a und 5ΐ> für die Wellen 3a und 4a der Rollen 3 und 4 befinden. The ends 3a and 4a of two rollers 3 and 4 protrude through a slot in a side wall 2 of a processing tank for the photographic recording medium, shown in detail in FIG. 2, into the space outside the processing tank. The ends 3a and 4a are mounted in corresponding bores 5a and 5b of a bearing block 5 which - as can be seen from FIG. 1 - consists of a diamond-shaped disc with rounded corners and incisions 5 ° and 5d. The incisions 5c and ^ d are widened at their ends to better compensate for bending stresses. Resilient arms 5e and 5f of the bearing block 5 are formed by the incisions 5c and 5d, in which the bores 5a and 5ΐ> for the shafts 3a and 4a of the rollers 3 and 4 are located.
Rund um die Bohrungen 5a und 5b weist der Lagerblock 5 zu den Bohrungen konzentrische, hohlzylinderförmige Fortsätze 5s und 5h- auf. Diese verstärken die Lager für die Enden 3a und 4a der Walzen 3 und 4.The bearing block 5 has around the bores 5a and 5b Hollow cylindrical extensions concentric to the bores 5s and 5h- open. These reinforce the camp for that Ends 3a and 4a of rollers 3 and 4.
Die federnden Arme 5e und 5f des Lagerblockes 5 halten die Walzen 3 und 4 gegeneinander. Zwischen den Walzen 3 und wird in bekannter Weise der fotografische Aufzeichnungsträger 6 geführt. Der Führungsblock 5 ist einstückig aus korrosionsbeständigem und quellfestem Kunststoff gespritzt. Ein geeigneter Kunststoff wird beispielsweise von der FirmaThe resilient arms 5e and 5f of the bearing block 5 hold the Rollers 3 and 4 against each other. Between the rollers 3 and becomes the photographic recording medium in a known manner 6 led. The guide block 5 is made in one piece injection-molded corrosion-resistant and swell-proof plastic. A suitable plastic is available, for example, from the company

vertrieben. Die Walzen J und 4 bilden mit dem Lagerblock 5 nach Figur 1 eine Einheit, die in den Schlitz 1 der Tankwände 2 eingesetzt werden und zur Reinigung leicht entnommen werden kann.expelled. The rollers J and 4 form with the bearing block 5 according to FIG. 1, a unit which can be inserted into the slot 1 of the tank walls 2 and is easy to clean can be taken.
Für den Fall, dass es erforderlich ist, die Walzenpaare an den Tankwänden zu befestigen, was vor allem bei angetriebenen Walzen der Fall ist, weisen die Blöcke 5 Bohrungen bzw. Gewinde 5i und 5k auf, an denen sie durch Schrauben an den Gerätewänden 2, die entsprechende Durchbrüche aufweisen, leicht lösbar befestigt werden können.In the event that it is necessary to attach the roller pairs to the tank walls, which is especially the case with driven Rolling is the case, the blocks have 5 bores or threads 5i and 5k, on which they are screwed can be easily detachably attached to the device walls 2, which have corresponding openings.
Die Erfindung ist nicht auf das Ausführungsbeispiel beschränkt. So können die Enden der Einschnitte 5c und 5d auch mit grösseren und kleineren Krümmungsradien abgerundet sein. Ferner ist es möglich, den Lagerblock etwa in Form eines Rechtecks mit prisoatisehen Fortsätzen 5g und 5h auszubilden.The invention is not restricted to the exemplary embodiment. So the ends of the incisions 5c and 5d also be rounded with larger and smaller radii of curvature. It is also possible to give the bearing block approximately the shape of a rectangle with prismatic extensions 5g and 5h to train.
