514 Separation and Transportation of Works Using Elliptical Vibration : The Case of Vertical Vibration over the Jumping Limit

Abstract

This paper describes the separation and transportation of works using elliptical vibration in the condition to exceed the jumping limit. When the vertical vibration is 1.2G-1.8G, gappy works jump and the characteristics of transportation change considerably. On the other hand, flat works don't jump and the characteristics change little. This phenomenon allows us to separate gappy works from flat one at high speed, because the relative velocity of them is widened. By measuring the pressure fluctuation between table and flat work, we made clear the cause that flat works don't jump in the condition to exceed the jumping limit.
