1. Field of the Invention

The invention relates to the field of photography, and particularly to a photosensitive material processing apparatus.

2. Background of the Invention

The processing of photosensitive material involves a series of steps such as developing, bleaching, fixing, washing, and drying. These steps lend themselves to mechanization by conveying a continuous web of film or cut sheets of film or photographic paper sequentially through a series of stations or tanks, each one containing a different processing liquid appropriate to the process step at that station.

There are various sizes of photographic film processing apparatus, i.e., large photofinishing apparatus and microlabs. A large photofinishing apparatus utilizes tanks that contain approximately 100 liters of each processing solution. A small photofinishing apparatus or microlab utilizes tanks that may contain less than 10 liters of processing solution.

Typically large photofinishing apparatus and microlabs utilize fixed and integrated horizontal and vertical arrangements of racks and tanks. The problem with fixed or integrated photofinishing apparatus and microlabs is that their rack and tank configuration are arranged on a horizontal surface i.e. a floor. This arrangement requires a large amount of floor space.

In addition the foregoing arrangement of racks and tanks is fixed according to the photographic process steps (developer, bleach, fix and wash) being utilized in the photographic processor. If the site that one wants to utilize for the photographic processor did not contain sufficient horizontal floor space, the photographic processor could not be installed. In the event, an existing photographic processor was placed in a horizontal space and one wanted to modify the processes sequentially performed in the processor by adding additional racks and tanks, one is constrained by the amount of horizontal space available.

Furthermore, if a rack and tank has to be eliminated from the process sequence, the rack and tank are skipped by the use of a cross over. The space that the rack and tank occupied is not eliminated because the rack and the tank have not been removed. A cross over has been added. Thus, no additional space is gained. Not only does the foregoing create unusable space, it adds excess cross over time to the process step. If the change in process sequence requires the addition of a rack and tank, the inflexibility of current fixed integrated rack and tank designs allow no space or means to add additional racks and tanks.

The within arrangement of processing modules allows one to add or subtract processing modules in either a horizontal or a vertical direction to solve the space constraints and the rigidity of prior photographic processor designs. A vertical arrangement of processing modules requires a much smaller space than a horizontal arrangement of processing modules and allows for larger more complex processes without the addition of any space.

Different photosensitive materials require different amounts of time for different parts of the process, i.e., photosensitive materials with thicker gelatins require longer wash times. Thus, the ability to add or subtract modules in the same horizontal space is a real advantage.

The ability to configure a photographic processor differently by adding or eliminating a module or the ability to combine modules horizontally or vertically allows one to position the processor more conveniently in the site space taking better advantage of the shape of the site space. Thus, permitting the photographic processor to be used in more locations.

The foregoing is accomplished by providing an apparatus for processing photosensitive materials, which comprises: a container which contains a channel through which a processing solution flows, the entrance and exit of the channel are upturned to contain processing solution within the channel; means coupled to the channel for transporting the photosensitive material from the channel entrance, through the channel, to the channel exit, the channel and the means are relatively dimensioned so that a small volume for holding processing solution and photosensitive material is formed between the channel and the means; wherein the means form a module and two or more modules may be interconnected and means for circulating the processing solution through the small volume and said modules.

Referring now to the drawings in detail, and more particularly to FIG. 1, the reference character 10 represents a processing module, which may stand alone or be easily combined or adjoined with other processing modules 10 to form a continuous low volume unit for processing photosensitive materials.

Processing module 10 includes: a container 11; an upturned entrance channel 100 (described in the description of FIG. 2); an entry transport roller assembly 12; transport roller assemblies 13; an exit transport roller assembly 15; an upturned exit channel 101 (described in the description of FIG. 2); high impingement slot nozzles 17a, 17b and 17c; a drive 16 and a rotating assembly 18, assembly 18 may be any known means for turning drive 16, i.e., a motor, a gear, a belt, a chain, etc. An access hole 61 is provided in container 11. Hole 61 is utilized for the interconnection of modules 10. Assemblies 12, 13 and 15 are positioned within container 11 in the vicinity of the walls of container 11 and slot nozzles 17a, 17b and 17c are positioned within the vicinity of the walls of container 11. Drive 16 is connected to roller assemblies 12, 13 and 15 and turning assembly 18 and assembly 16 is used to transmit the motion of assembly 18 to assemblies 12, 13 and 15.

Roller assemblies 12, 13, and 15, and slot nozzles 17a, 17b and 17c may be easily inserted into or removed from container 11. Roller assembly 13 includes: a top roller 22; a bottom roller 23; tension springs 62, which holds top roller 22 in compression with respect to bottom roller 23; a bearing bracket 26; and a channel section 24.

Opening 25 on the entrance side of section 24 may also be relieved, tapered or larger than the exit side of section 24 to accommodate rigidity variations of various types of photosensitive material 21. Channel opening 25 forms a portion of processing channel 25. Rollers 22 and 23 may be drive or driven rollers and rollers 22 and 23 are connected to bracket 26. Rollers 22 and 23 are rotated by intermeshing gears 28.

Photosensitive material 21 is transported in either direction A or direction B automatically through processing channel 25 by roller assemblies 12, 13 and 15. Photosensitive material 21 may be in a cut sheet or roll format or photosensitive material 21 may be simultaneously in a roll and simultaneously in a cut sheet format. Photosensitive material 21 may contain an emulsion on either or both of its surfaces.

When cover 20 is placed on container 11 a light tight enclosure is formed. Thus, module 10 with its associated recirculation system 60, which is described in the description of FIG. 5, will be a stand alone light tight module that is capable of processing photosensitive material, i.e., a monobath. When two or more modules 10 are combined a multi-stage continuous processing unit may be formed. The combination of one or more modules 10 will be more fully set forth in the description of FIG. 6.

FIG. 5 is a schematic drawing of processing solution recirculation system 60 of the apparatus of this invention. Module 10 is designed in a manner to minimize the volume of channel 25. The outlets 44, 45, 46 and 47 of module 10 are connected to recirculating pump 80 via conduit 85. Recirculating pump 80 is connected to manifold 64 via conduit 63 and manifold 64 is coupled to filter 65 via conduit 66. Filter 65 is connected to heat exchanger 86 and heat exchanger 86 is connected to channel 25 via conduit 4. Heat exchanger 86 is also connected to control logic 67 via wire 68. Control logic 67 is connected to heat exchanger 86 via wire 70 and sensor 52 is connected to control logic 67 via wire 71. Metering pumps 72, 73 and 74 are respectively connected to manifold 64 via conduits 75, 76 and 77.

The photographic processing chemicals that comprise the photographic solution are placed in metering pumps 72, 73 and 74. Pumps 72, 73 and 74 are used to place the correct amount of chemicals in manifold 64, when photosensitive material sensor 210 senses that material 21 (FIG. 1) is entering channel 25, sensor 210 transmits a signal to pumps 72, 73 and 74 via line 211 and control logic 67. Manifold 64 introduces the photographic processing solution into conduit 66.

The photographic processing solution flows into filter 65 via conduit 66. Filter 65 removes contaminants and debris that may be contained in the photographic processing solution. After the photographic processing solution has been filtered, the solution enters heat exchanger 86.

Sensor 52 senses the solution level and sensor 8 senses the temperature of the solution and respectively transmits the solution level and temperature of the solution to control logic 67 via wires 71 and 7. For example, control logic 67 is the series CN 310 solid state temperature controller manufactured by Omega Engineering, Inc. of 1 Omega Drive, Stamford, Conn. 06907. Logic 67 compares the solution temperature sensed by sensor 8 and the temperature that exchanger 86 transmitted to logic 67 via wire 70. Logic 67 will inform exchanger 86 to add or remove heat from the solution. Thus, logic 67 and heat exchanger 86 modify the temperature of the solution and maintain the solution temperature at the desired level.

Sensor 52 senses the solution level in channel 25 and transmits the sensed solution level to control logic 67 via wire 71. Logic 67 compares the solution level sensed by sensor 52 via wire 71 to the solution level set in logic 67. Logic 67 will inform pumps 72, 73 and 74 via wire 83 to add additional solution if the solution level is low. Once the solution level is at the desired set point control logic 67 will inform pumps 72, 73 and 74 to stop adding additional solution.

Any excess solution may either be pumped out of module 10 or removed through level drain overflow 84 via conduit 81 into container 82.

At this point the solution enters module 10 via inlets 41, 42 and 43. When module 10 contains too much solution the excess solution will be removed by overflow conduit 51, drain overflow 84 and conduit 81 and flow into reservoir 82. The solution level of reservoir 82 is monitored by sensor 212. Sensor 212 is connected to control logic 67 via line 213. When sensor 212 senses the presence of solution in reservoir 82, a signal is transmitted to logic 67 via line 213 and logic 67 enables pump 214. Thereupon pump 214 pumps solution into manifold 64. When sensor 212 does not sense the presence of solution, pump 214 is disabled by the signal transmitted via line 213 and logic 67. When solution in reservoir 82 reaches overflow 215 the solution will be transmitted through conduit 216 into reservoir 217. The remaining solution will circulate through channel 25 and reach outlet lines 44, 45, 46 and 47. Thereupon, the solution will pass from outlet lines 44, 45, 46 and 47 to conduit line 85 to recirculation pump 80. The photographic solution contained in the apparatus of this invention, when exposed to the photosensitive material, will reach a seasoned state more rapidly than prior art systems, because the volume of the photographic processing solution is less.

FIG. 6 is a drawing that shows the coupling of a plurality of modules 10 having a light tight horizontal cover 20 to form a continuous photographic processor. Modules 10 may contain the same or similar processing solution to increase the productivity of the processor or perform different processing functions by containing different processing solutions. Any number of modules 10 may be interconnected, only three have been shown for illustrative purposes. Drive 16 from each of the modules 10 is interconnected via drive access holes 61, by any known means, i.e., couplings, keyways, belts, chains, hex drives, etc. Photosensitive material 21 (not shown) enters the first module 10 on the left, via upturned entrance channel 100 enters module 10 via upturned entrance channel 100 travels from module 10 to module 10 via light tight interconnecting cross over 220 and exits the last module 10 via upturned exit channel 101. Modules 10 are physically connected to each other by any known mechanical fastening means, i.e., screws, snaps, rivets etc. It is obvious to one skilled in the art that photosensitive material 21 (not shown) may travel from right module 10 to left module 10 and is dependent on the chemicals in module 10.

FIG. 7 is a drawing that shows the integration of a plurality of modules 10 into a single body 102 to form a continuous photographic processor, that contains more than one channel. Each module 10 may contain one or more roller assemblies and slot nozzles 17 in order to form a continuous photographic processor. Modules 10 may contain the same or similar processing solution to increase the productivity of the processor or perform different processing functions by containing different processing solutions. Any number of modules 10 may be interconnected, only three have been shown for illustrative purposes. Drive 16 (FIG. 1) from each of the modules 10 is interconnected via drive access hole 61, by any known means, i.e., drives 221 and 222. Modules 10 are physically connected to each other by any known mechanical fastening means, i.e., snaps, rivets etc. Photosensitive material 21 (not shown) travels from bottom module 10 to middle module 10 via light tight interconnecting cross over 223, through middle module 10 to top module 10 via light tight interconnecting cross over 224 and exits the last module 10 via upturned exit channel 101. It is obvious to one skilled in the art that photosensitive material 21 (not shown) may travel from top module 10 to bottom module 10 and is dependent on the chemicals contained in modules 10.

FIG. 8 is a drawing that shows the coupling and vertical stacking of a plurality of modules 10 having a light tight horizontal cover 20 to form a continuous photographic processor. Modules 10 may contain the same or similar processing solution to increase the productivity of the processor or perform different processing functions by containing different processing solutions. Any number of modules 10 may be interconnected, only three have been shown for illustrative purposes. Drive 16 from two of the modules 10 are interconnected via drive access holes 61, by any known means, i.e., couplings, keyways, belts, chains, hex drives, etc. Vertical drive 221 is connected to drive 16 by any known means such as gears, chains, belts, flexible shafts, couplings, etc. Vertical drive 221 from each material 21 (not shown) may travel from right module 10 to left module 10 and is dependent on the chemicals in module 10. Photosensitive material 21 (not shown) enters module 10 via upturned entrance channel 10 and travels from left module 10 to right module 10 via light tight interconnecting cross over 220 and then travels from right lower module 10 to top module 10 via light tight cross over 223. Thereupon material 21 exits via upturned exit channel 101. Modules 10 are physically connected to each other by any known mechanical fastening means, i.e., screws, snaps, rivets, etc. It is obvious to one skilled in the art that any number of modules 10 may be interconnected in the aforementioned manner.

The above specification describes a new and improved apparatus for processing photosensitive materials. It is realized that the above description may indicate to those skilled in the art additional ways in which the principles of this invention may be used without departing from the spirit. It is, therefore, intended that this invention be limited only by the scope of the appended claims.
