Abstract
An I.S. machine system has a number of mechanisms which are driven by an inverter drive and a number of machine and section mechanisms which are driven by profiled motion actuators which are controlled by repetitive sequencers associated with each actuator. These repetitive sequencers are synchronized by taking the reference signal from a master clock which supplies the reference signal to the inverters and converts it to a once/cut sync signal for the machine mechanisms operated by profiled motion actuators and to a once/cycle sync signal for the section mechanisms and controllers.
Claims10
A machine for forming glass containers from discrete gobs repetitively cut from a runner of molten glass comprising
- at least one controller having a repetitive sequencer synchronized with a once/cut sync signal,
- at least one controller having a repetitive sequencer synchronized with a once/cycle sync signal,
- a high frequency source which produces a reference signal,
- means for converting said reference signal to a once/cut sync signal,
- delivery means for delivering said once/cut sync signal to said at least one controller having said repetitive sequencer synchronized with a once/cut sync signal for synchronizing said repetitive sequencer,
- means for converting said once/cut sync signal to a once/cycle sync signal and for delivering said once/cycle sync signal to said at least one controller having said repetitive sequencer synchronized with a once/cycle sync signal for synchronizing said repetitive sequencer.
