Chemical replenishing system

摘要

A chemical replenisher system for supplying developer and fixer chemicals to a processor is disclosed. A developer and fixer tank are disposed side-by-side and coupled to the processor by way of hoses. A container-coded dispenser atop the tanks provides a substantially error-free arrangement for introducing the component chemicals into the tanks. A unique outline geometry is associated with each component container. By relating this geometry to a corresponding opening in a template of the dispenser, the introduction of the component chemicals is made error-free. The template openings also serve as guides for the containers. Uniquely designed knife assemblies are disposed below the template openings for piercing the tops of the sealed, chemical-filled containers upon inserting the containers into the template openings. Water is supplied under increased pressure as a mixing source is provided to each tank. A system of sensors provides low level alarm activation and automatic water shut-off.
