ABSTRACT:
A control system for operation of the individual sections of a glassware forming machine includes a shaft position encoder associated with the mechanical drive for the feeder, and a digital computer for programming various events in the machine cycle in accordance with certain boundary event timings. The shaft encoder output is converted to binary coded decimal (BCD) form and is fed to the digital computer through a priority program which permits routine starting and stopping of the machine and its various sections, and which also includes manual means for setting up the desired cycle of operation for the various mechanisms associated with a given section and for later transferring these settings to the other sections of the machine with operation of each section being phase delayed in accordance with a predetermined "firing order". These settings can be revised during operation of the machine as a result of the program stored in the digital computer. In addition, limits may be imposed upon the revisions which will be permitted.
