An electronic control system for an automatic glassware forming machine includes a plurality of position sensors for monitoring the motions of individual glassware forming mechanisms. The sensors generate output signals which define the start and stop times and/or motion of the respective forming mechanisms. The electronic control is responsive to the sensor output signals for identifying any mechanical dead times in the forming cycle. Mechanical dead time is defined as time during which no machine motions are occurring, but could be occurring without interfering with essential heat transfer functions. The electronic control can then reduce or remove selected mechanical dead times to reduce the machine cycle length, and consequently, increase the production rate of the machine.
In a glassware forming machine having glassware forming means for forming glassware articles from gobs of molten glass in a timed series of predetermined forming steps in response to a plurality of control signals, and control means for generating the control signals, the improvement comprising:
A method of controlling a glassware forming machine having glassware forming means of forming glassware articles from gobs of molten glass in a timed series of predetermined forming steps in response to a plurality of control signals, and control means for generating the control signals, comprising the steps of:
In a glassware forming machine having glassware forming means for forming glassware articles from gobs of molten glass in a timed, predetermined sequence of forming steps in response to a plurality of control signals, and control means for generating the control signals, means for changing the timing of the control signals comprising:
