  • Self tuning vibratory control means
    Patent number: 6675955
    Abstract: A product delivery system and method are provided including an electromechanical vibratory conveyor which has a product conveying member, a vibrator for vibrating the product conveyor and a control system for controlling electronically the vibration of the product conveying member both statically and dynamically to optimize performance both with and without product on the product conveying member. The vibration of the product conveying member is tuned both statically and dynamically with a coarse tuning followed by a fine tuning. An improved pulse width modulation drive circuit for the vibrator includes vibrating frequency and amplitude varying devices for adjusting the frequency and amplitude of the vibrator for increased efficiency, optimized performance and reduction in energy consumption. Several redundant safety devices to safeguard the switching devices and the vibrator are also provided.
    Type: Grant
