Abstract
A system and method for the optimization of the cycles of events occurring in an I.S. machine that automatically optimizes the cycles of events occurring in an I.S. machine by using information relating to the characteristics of the hot glass containers manufactured by the I.S. machine obtained by monitoring the hot glass containers immediately subsequent to their manufacture. Optionally, information relating to process values associated with the operation of the I.S. machine may also be monitored and used in the optimization of the cycles of events occurring in the I.S. machine. Also optionally, the active limits of the event times may be modified by an operator based upon observations of the operation of the I.S. machine.
Claims20
A system for automatically optimizing event timing in the operation of an I.S. machine, comprising:
- a glass container measurement system that provides container measurement information indicative of certain characteristics of hot glass containers manufactured by the I.S. machine;
- a controller that uses the container measurement information to produce desired process durations used to operate the I.S. machine to produce glass containers having desired characteristics;
- a cyclic timing adjustment system which automatically transforms the desired process durations from the controller into machine timing signals which are applied to the I.S. machine by imposing constraints to maintain a predetermined cyclic order, to avoid mechanical interference or collisions, and to maintain a predetermined total or common cycle period;
- wherein when the cyclic timing adjustment system adjusts a machine timing signal to increase or decrease a desired process duration, the cyclic timing adjustment system maintains the predetermined total or common cycle period;
- and
- wherein when the cyclic timing adjustment system increase one desired process duration, the cyclic timing adjustment system decreases another one of the desired process durations to maintain the predetermined total or common cycle period.
A system for automatically optimizing event timing in the operation of an I.S. machine, comprising:
- a glass container measurement system that is arranged and configured 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, said glass container measurement system providing container measurement information indicative of certain characteristics of hot glass containers manufactured by the I.S. machine;
- at least one sensor that provides one or more measurements of process values within the I.S. machine, the measurements of process values being provided as process measurement values;
- a controller that uses the process measurement values and the container measurement information to produce desired process durations used to operate the I.S. machine to produce glass containers having desired characteristics;
- a cyclic timing adjustment system which automatically transforms the desired process durations from the controller into machine timing signals which are applied to the I.S. machine by imposing constraints to maintain a predetermined cyclic order, to avoid mechanical interference or collisions, and to maintain a predetermined total or common cycle period;
- wherein when the cyclic timing adjustment system adjusts a machine timing signal to increase or decrease a desired process duration, the cyclic timing adjustment system maintains the predetermined total or common cycle period;
- and
- wherein when the cyclic timing adjustment system increases one desired process duration, the cyclic timing adjustment system decreases another one of the desired process durations to maintain the predetermined total common cycle period.
A method for automatically optimizing event timing in the operation of an I.S. machine, comprising:
- providing container measurement information indicative of certain characteristics of hot glass containers manufactured by the I.S. machine;
- using the container measurement information to produce desired process durations used to operate the I.S. machine to produce glass containers having desired characteristics;
- automatically transforming the desired process durations from the controller into machine timing signals which are applied to the I.S. machine by imposing constraints to maintain a predetermined cyclic order, to avoid mechanical interference or collisions, and to maintain a predetermined total or common cycle period;
- wherein automatically transforming the desired process durations from the controller into machine timing signals includes adjusting a machine timing signal to increase or decrease a desired process duration while maintaining the predetermined total or common cycle period;
- and
- wherein when automatically transforming the desired process duration from the controller into machine timing signals includes adjusting a machine timing signal to increase one desired process duration another desired process duration is decreased to maintain the predetermined total or common cycle period.
