Utilization of wall thickness measurement in combination with thermal imaging of containers

摘要

A closed loop temperature and wall thickness-based control system (48) for improving process yield and quality while reducing dependence on operator skill utilizes intensity information (38) from a hot end container imaging system (30) and wall thickness information (40) from a hot glass container wall thickness measurement system (32). By utilizing both the container intensity information and the measured wall thickness information it is possible to provide separate feedback signals responsive to temperature variations and thickness variations. These signals are used to implement automatic closed loop control of the I.S. machine.
