- DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The automated processlng apparatus 1 shown in Fig.
1 comprises an inlet station 10 adapted to receive film units 2 of the type described with their longitudinal axes extending ~across the main feed path through the apparatus.
Located in sequence along the film unit feed path from the inlet station 10 are a processing zone 11 including a plurality of liquid processing stations, a drying station 12 and an outlet 14. Located on one side of the apparatus are a plurality of conduits 15 which introduce and discharge processing liquid into respective processing stations in a tlmed sequence to be described subsequently in more detail.
., .. .. ~
~0~7~2(;~
As shown, the apparatus 1 is adapted to be incorporated in a greater automated apparatus, illustrated schematlcally as including inlet and outlet conveyors 16 and 17.
Referring now to Figs. 2, 3 and 4, the drive system for rotating the film units on their longitudinal axes during passage through the apparatus will be described.
As shown, a film drive motor 20 has an output shaft 21 on which are affixed a plurality of worm gears 22. Gears 23 respectively drivingly mate with gears 22 for transmitting drive from the motor 20 beneath the film unit feed path, via shafts 24, to drive pulleys 25. Drivingly coupling pulleys 25 respectively with pulleys 26 are "O-ring" drive belts 27.
Pulleys`26 are mounted for free rotation on (not keyed to) shafts 34 a~d of diameter such that the O-ring belt passing therearound can drivi.ngly engage an end portion of a film unit, which is supported adjacent thereto by the film unit transport system in a manner next to be described with continued reference to Figs. 2-4.
The fllm unit transport system comprises a trans-port drive motor 30 having a drive shaft 31 on which areàffixed worm gears 32. Gears 33 respectively mate with each of the worm gears and are keyed on shafts 34 to transmit rotation to indexing discs 35, which likewise are keyed to shafts 34, one on each slde of the film unit transport path as best shown in Figs. 2 and 4. As also shown in Figs. 3 and 4, each of the film unit transport discs have a pair of notches 35a and 35b extending diagonally inwardly from the disc periphery. The notches 35a are diametrically opposite notches 35b on the discs and all tPanspor-t~ discs are of the same diameter and oriented Oll their shafts so that one notch on each disc will move to the aligned, film-unit-passing ~, 97~LZO
orientation shown in Fig. 3 during a one-half cycle of rotation of the disc 35. As shown in Fig. 3, the off radial - slant of the slot in the disc îs directed so as to assist retention of the shaft of a film unit in the upward transport of the film unit (clockwise rotation of the disc as viewed ln Fig. 3) and assist in gravity discharge of the film unit shaft into the notch of the next contiguous disc during downward transport of the film unit.
As shown in Figs. 2-4, a timing disc 40 is keyed to an extension 41 of one of the transport disc shafts 34 and rotates synchronously with the timing discs. The timing disc includes two switch actuating notches 42, diametrically opposed on the disc periphery. A control switch 43, shown in more detail in Fig. 6, is mounted for movement toward and away from the timing disc 40, and biased toward the disc.
After movement ~o the dotted-line position shown in Fig. 6 by rotatLon of' the disc 40, the switch 43 is retained in that position and follows the outer disc periphery until falling into the opposite slot, after a 180 rotation of the shaft 41 (and of all transport discs 35). The movement back into a slot 42 actuates de-energization of motor 30 and of a transport cycle as will be explained in more detail after a description of the film units 2 utilized in apparatus 1.
It will be appreciated that synchronization could be accomplished by optical sensors or other position detecting systems known in the art.
As best shown in Figs. 2 and 4, the film unit 2 can comprise an elongated shaft 50, having on one end thereof a drive disc 51 having a serrated or otherwise roughened periphera~l edge. The shaft 50 is of sufficient length and the drive disc 51 of sufficient diameter that the disc 51 . -: : .
. ~)9~'~ZO
can drivingly engage O-rings 27, when supported by transport discs 35 as shown in Fig. 4. On the shaft 50 a plurality of film discs 54 aré mounted by a central aperture. A central portion of the film disc provides frictional or keyed engage-ment between the shaft and film disc and also spaces adJacent film discs sufficiently to avoid inter-film contact and allow processing solution access.
In operation, a film unit is released through the inlet 10 and can roll into a nested position in slots 35a of the first pair of transport discs as shown in Fig. 3. A
cycle of operation is then actuated by the-operator and motor 30 is energized to move transport discs 35 and timing disc 40 through a 180 rotation. This rotation locates the film unit in a sùpported position in the next transport disc 35 which, as will be apparent from Figs. 1 and 4, will locate the lower portion of the film discs in the first processing tray. Motor 20 can be energized simultaneously with motor 30 and drive is thus transmitted to the film unit via "~-ring" belt 27 and drive disc 51 of the film unit;
however, motor 20 is not de-energized after the 180 rotation and continues to rotate the film unit in the first processing tray 60. After a predetermined period of treatment in the first processing tray, the motor 30 is again energized to transport the film unit to the next processing tray in the same manner described above. Concurrently a new film unit can be fed into the processing position in the first processing tray. ~he motor 20 can desirably remain energized during the film unit transport and continues to rotate the film unit during transport between processing trays. Control means, of a type readily understood by one skilled in the art and not described herein in detail, continue to sequentially ~(19~2~J
initiate successive film transport cycIes of motor 30 between predeterminedly timed processing cycles until the film unit has passed through drying section 12 and exits the apparatus with film fully processed.
- In timed relation with the film unit transport between processing trays, predetermined quantities of processing solutions, such as developer, fix and wash solutions, are introduced into the processing trays by conduits 15. More specifically, a predetermined quantity of déveloper is introduced into processing tray ~0 prior to each processing cycle and discharged after completion of the cycle. The discharge and replenishment desirably is effected during film unit transport to the next tray, which may contain, e.g., a newly introduced fix solution. It will be noted that the rotation of the film unit during processing allows substantially less than total immersion of the film and thus the liquids for a single processing cycle can be introduced and discharged for each film unit treatment. The electrically-controlled plumbing system for performing these functions is of a type readily understood and is not described herein in detail. However, larger liquid reservoirs could - be provided for processing the film units or recirculating - liquid to the shallow trays 60.
It will be apparent to one skilled in the art that the appara~tus disclosed is admirally suited for continuous throughput of film requiring differing processing periods in the different solutions. 'l'hat is, a plural number of developer, fix and/or wash trays can be provided so as to additively provide a seleGted processing time in a particular solution, e.g., the first two trays could be developer, the next two fix and last four wash if the chemistry of the developing _9_ ~L097~a~0 process and film so required Thus, with the cycle between inter-tray transports remaining constant to allow continuous throughput, the treatment time with a particular solution can differ by arrangement of solutions in the trays.
Although the embodiment of the invention just described employs a plurality of reservoirs 60 with different fluids, it will be appreciated that certain advantages of the present invention pertain to the use of a single tray embodiment. For example, the film unit could be supported and rotated in a single tray 60 with different processing fluids sequentially introduced into, and discharged from, the tray.
Referring now to ~ig. 5, it will be seen that another important feature of the present invention provides for the continuous rotation of the fi.lm units during transport between processing trays. As shown, the drive disc 51 is maintained by gravity in driving engagement with a f`irst belt 26 substantially until it moves into nesting position on the next successive transport discs 35. This spinning action is particularly advantageous in maintaining processing solution on the film surface so as not to accumulate in large masses during transport. Also this spinning action can be utilized to effect removal of residual processing liquid from the previous tray prior to introduction of the film into ~ different solution tray, in whlch case appropriate - baffle structure, of a type known in the art but not shown, may be desired.
As will be noted in ~ig. Il~, which for ease of illustration shows only five processing stations~ a separate drive can.be provided to particular stations, for example by , ~
~0~71ZO
a shaft 70. Thus if it is desirable to provide a higher velocity rotation for drying, separate faster drive`can be supplied to pulléy 71 and belt 72.
'l'he invention has been described in detail with particular reference to preferred embodiments thereo~f, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.

Devices for processing film elements of other formats, e.g., chips, or small sheets have not been so common. One popular approach is to support a plurality of film chips to be processed in a rack and sequentially dip ` the rack intO treating reservoirs.
