Publication number: 20240002270Abstract: Methods and systems for controlling vertical glass distribution are provided. A traversing pyrometer periodically measures a parison actual temperature after the parisons exit a blank mold. The thermal camera takes a thermal image of each glass container after the glass container exits the blow mold. A vertical glass signature extraction module extracts a vertical glass distribution signature. A parison temperature estimator determines a parison estimated temperature for each vertical glass distribution signature obtained based on the vertical glass distribution signature, a most recently measured parison actual temperature and a parison stretch time. A parison temperature summer compares the parison estimated temperature to a parison set point temperature to determine a parison temperature error. A parison temperature control controls a blank mold contact time based on the parison temperature error.Type: ApplicationFiled: September 18, 2023Publication date: January 4, 2024Applicant: Emhart Glass S.A.Inventor: Jonathan S.
