Abstract
An improved transport for developing film in a photographic film processor, the transport received in a tank having film processing liquids therein. The transport characterized by having a housing with film guide rollers that are mounted on removable bearings so that the individual rollers can be quickly removed from the housing without having to disassemble the housing end plates. Further, the transport is modular in design so that the housing end plates with rollers can be added or subtracted for changing the film process cycle time.
Claims11
A transport for developing film in a photographic film processor, the transport received in a tank having film processing liquids therein, the transport comprising:
- a transport housing having a pair of end plates joined together in a spaced relationship by tie rods;
- a plurality of rollers, the opposite ends of the rollers rotatably mounted on removable bearings, the bearings received in a press-fit in apertures in the sides of the end plates, the diameter of the apertures greater than the outer diameter of the rollers so that when the bearings are removed from the apertures, the rollers can be slidably received through the apertures without removing the end plates from the tie rods, the rollers disposed in a spaced relationship to each other for receiving the film therebetween and guiding the film downwardly along one side of the tank and upwardly along the opposite side of the tank;
- and
- means for rotating the rollers on the housing.
A transport for developing film in a photographic film processor, the transport received in a tank having film processing liquids therein, the transport comprising:
- a modular transport housing having a plurality of end plates joined end-to-end, the end plates forming two sides of the housing and joined together in a spaced relationship by tie rods;
- a plurality of rollers, the opposite ends of the rollers rotatably mounted on removable bearings, the bearings received in a press-fit in apertures in the sides of the end plates, the diameter of the apertures greater than the outer diameter of the rollers so that when the bearings are removed from the apertures, the rollers can be slidably received through the apertures without removing the end plates from the tie rods, the rollers disposed in a spaced relationship to each other for receiving the film therebetween and guiding the film downwardly along one side of the tank and upwardly along the opposite side of the tank;
- and
- a plurality of gears attached to one end of the rollers and forming a gear train driven by an endless chain.
