Abstract
A system and method for automatically adjusting the motion and timing of pusher mechanisms in an I.S. machine to maintain desired spacing and lateral alignment of glass containers on a conveyor taking them from the I.S. machine where they are molded. The measured glass container placement and the desired glass container placement are used to vary the operation of the pusher mechanisms in a manner tending to obtain the desired placement.
Claims25
A system for correctly placing glass containers formed by an I.S. machine onto a conveyor, comprising:
- a pusher mechanism for moving glass containers from a deadplate to the conveyor;
- a glass container placement measurement system that provides a measured glass container placement signal indicative of the actual locations of glass containers moved onto the conveyer by the pusher mechanism;
- apparatus for comparing the measured glass container placement signal with a desired glass container placement signal and generating a glass container placement error signal;
- and
- a control system using the glass container placement error signal to provide modified pusher parameters to vary the operation of the pusher mechanism in a manner that will cause the glass container placement error signal to be diminished.
