Abstract
PURPOSE:To aim at enhancing the capacity of conveyance by a granular conveying electromagnetic vibrator by selecting a parabolic waveform for a drive voltage applied to the electromagnetic vibrator. CONSTITUTION:A parabolic signal Vs delivered from parabolic signal generator 20 is multiplied by an amplitude instruction signal delivered from an amplitude instructing unit 9, and is delivered to a comparator 13 which compares thus inputted signal with a triangular signal Vc, and which then delivers a PWM signal to a transistor driver 14. The transistor driver 14 turns on and off transistors Tr1, Tr2 in a PWM inverter 4, and accordingly, the PWM inverter 14 delivers a drive voltage VOS having a parabolic waveform to a drive coil 3 so that an electromagnetic vibrator is driven to vibrate. With this arrangement, the amplitude of vibration can be made to be larger that of a sinusoidal waveform signal, thereby it is possible to enhance the capacity of conveyance.
