Date Nov. 28, 1991.In photographic processing, the chemistry needs to be replenished periodically in order to produce optimum results. Known replenishment systems utilize replenishers in liquid form which are dispensed according to volume. These systems require the use of a pump which is both accurate and relatively inexpensive. Described herein is a replenishment system which uses a weighing system with a series of intermediate containers to dispense replenishment materials. The system comprises a weighing device which has three intermediate containers supported on it. Each container is connected to its associated processing stage by a pipeline. Flow of replenisher materials from each container is controlled by respective valves which are interfaced with a computer. The computer is also interfaced with the weighing device and monitors the decrement in weight of the intermediate containers so that the exact amount of replenisher materials can be added. |
