Abstract
To use elliptical vibration, we can supply and separate the work which material and shape is similar at the same time. When the vertical vibration of elliptical vibration is larger than 1.0G, works jump and the characteristics of transportation change considerably. But some works don't jump because negative pressure is caused on contact face. As a result, it is possible to separation and transportation by the presence of jump. However, it is difficult to separate works with little difference or tiny works. In this study, we try these works by changing driving frequency. First, we examined that the influence of driving frequency on jump limit. Next, we examined that the influence of driving frequency on stability of the separation or velocity. Finally, from a result of these examinations, we choose optimal driving condition of the tiny work with little difference in the face side and reverse side. In this condition, we try separation and transportation a lot of works at fast and stable using elliptical vibration.
