Filed: 1992-03-31
Abstract: PURPOSE:To prevent troubles resulting from lack of charging time, by varying the ratio of the running time to the suspended time in one cycle through a speed changer by which the rotary speed of the motor and the packer can be arbitrarily changed. CONSTITUTION:An inverter 22 connected to an inverter motor 10 is jointed with a variable cam switch 17 through a detector 21 of the rotary angle.
