Title: Timing adjustment for gob feed to glass molding machine
Inventor: MORI YASUO
IPC: C03B11/16
Filed: 1981-04-17
Abstract: PURPOSE: To maintain a timing for gob feed constant, by detecting the time difference between the operation timing of molding and the timing of gob feed by the count number of clock pulses, comparing it with a set value so that the drive of gob feeder is controlled.  
     CONSTITUTION: The detector 16A for operation timing of a molding machine produces an output signal by the passage of a mold. This signal is inputted to the calculating circuit 28, and starts to count the clock pulses sent by the frequency demultiplier 18 for setting speed. When the output signal of the detector 16 of the timing of gob feed is inputted to the calculating circuit 18, the count of the clock pulses is stopped. Consequently, after the mold is passed through a specific point, the time difference upto the gob feed is detected as the count number of clock pulses and shown by the indicator 30. The count number is compared with the set value, the signal is sent to the D/A convertor 24 by the differential circuit 31 depending upon the deviation, and the rotating speed of the motor 15 for driving gob feeder is increased or reduced to make the deviation zero.
