A high speed intermittent drive, which operates at the resonance frequency of a vibration transportation machine by velocity feedback control, was developed. The intermittent drive enables high speed fixed-quantity supply of works. A conventional intermittent drive of a vibration transportation machine is used in processes such as stuffing a bag with snacks or supplements. Driving vibration transportation machine with small damping at the resonance frequency is efficient, because a big vibration is generated even by a small excitation force. However, driving at resonance frequency is difficult, because vibration characteristics are greatly affected by natural frequency change and disturbance near the resonance frequency. On the other hand, velocity feedback control increases the damping of a vibration transportation machine and suppresses the influence of natural frequency change and disturbance. In addition, it can drive and stop vibration quickly by means of large damping and enables high speed intermittent drive. The high speed intermittent drive realizes high speed fixed-quantity supply, in which the supply amount is in proportion to both amplitude and driving time of a vibration transportation machine, and reduces supply error to less than 5%.
