DEVICE FOR INDICATING RELATIVE FREQUENCY POSITION AMONG EACH MECHANISM IN GLASS INSTRUMENT MANUFACTURING DEVICE

摘要

Pulse generators are connected to those forming mechanisms to be monitored. A clock pulse source generates three hundred and sixty clock pulses for each machine cycle and the pulse generators generate one reset pulse for every 360 DEG of monitored forming means cycle. A switch means is provided for selecting the outputs of two of the pulse generators to be compared. The pulses generated by these selected generators are fed to a counter/display circuit having three inputs. A clock input receives the clock pulses generated by the clock pulse source. A clear input receives the reset pulse from the first selected generator. An enable input receives the reset pulse from the second selected generator. The counter/ display circuit counts the number of clock pulses received between the clear and enable pulses. The number of counted clock pulses represents the relative degree positioning between the selected forming mechanisms and can be displayed on a digital visual display. Alternatively, the counter/display circuit can receive pulses from a real time clock circuit and a selected forming operation generator to generate a display of operation per unit time, such as bottles per minute.
