A method and apparatus for controlling operation of a bag-forming and -filling packing apparatus for supplying unsealed packaged articles (45) to a rotary vacuum packaging machine at regular intervals, in which the rotary vacuum packing machine is subjected to significant variations in loads. A main controller (115) for receiving pulse signals calculates modulation of the pitch of pulses from a main motor (86) of the rotary vacuum packaging machine, and control elements (94, 95, 96, 97) each attached to a corresponding one of all servo motors (20, 30, 40, 76) of the bag-forming and -filling packaging machine individually and simultaneously control the rotation value of each servo motor. This configuration can avoid step-wise control of each servo motor and reduce impacts on a rotary section and a failure rate while maintaining a slow control operation. <IMAGE> |
