Abstract
A system and a method for improving process yield and quality while reducing dependence on operator skill by automatically adjusting I.S. machine timing and motions. Container pixel data information indicative of certain measurements of hot glass containers manufactured by the I.S. machine obtained with a multipoint, multispectral glass container measurement system is mathematically transformed into a reduced dimensional measured signature. Event timing signals to operate the cavities of the section of the I.S. machine in response to the measured signature and a preferred target signature are produced to automatically adjust the event timing of operations in the cavities of the section of the I.S. machine to diminish variations in the measured signature.
Claims21
A system for automatically adjusting the event timing of operations in cavities of a section of an I.S. machine, comprising:
- a multipoint, multispectral glass container measurement system that provides container pixel data information indicative of certain measurements of hot glass containers manufactured by the I.S. machine;
- a signature extraction block that mathematically transforms container pixel data information into a reduced dimensional measured signature;
- and
- a controller for producing event timing signals to operate the cavities of the section of the I.S. machine in response to the measured signature and a preferred target signature to automatically adjust the event timing of operations in the cavities of the section of the I.S. machine to diminish variations in the measured signature.
A system for automatically adjusting the event timing of operations in cavities of a section of an I.S. machine, comprising:
- a multipoint, multispectral glass container measurement system that is arranged to monitor radiation emitted by hot glass containers after they are formed and before they are cooled as they are conveyed away from the I.S. machine, wherein the container measurement system provides container pixel data information indicative of certain measurements of hot glass containers manufactured by the I.S. machine;
- a signature extraction block that mathematically transforms container pixel data information into a reduced dimensional measured signature;
- an element for providing a preferred target signature known to have previously provided desirable hot glass containers;
- and
- a controller for producing event timing signals to operate the cavities of the section of the I.S. machine in response to the measured signature and a preferred target signature to automatically adjust the event timing of operations in the cavities of the section of the I.S. machine to diminish variations in the measured signature.
