ABSTRACT:
A control system for a high-speed rotary washer spraying system designed particularly for plastic returnable bottles automatically regulates each process of the wash spraying system, namely, sequentially feeding bottles from an infeed conveyor means, inverting them by a worm/inverter means, receiving and simultaneously rotating each bottle in an inverted position through a plurality of washing, neutralizing and sanitizing treatment zones, and inverting each bottle to its original neck-up orientation for further processing. During the entire process, a programmable logic controller maintains, manages, and controls all pumps, valves, solenoids, and drive motor speeds as required by the process, and also provides for monitoring and adjusting fluid levels, alkalinity/acidity concentrations, and temperatures of the wash and neutralizing solutions. Alarm conditions that may present themselves during the washing, neutralizing, and sanitizing processes are flagged for human intervention, interaction, or acknowledgement. Such alarm conditions are out of range: fluid flow, temperature, pressure, conductivity and/or pH, fluid levels, and carousel and bottle RPM. The control system also includes specialized checks for clogged spray nozzles, and out of position fluid lances.
