| 摘要 | PURPOSE:To provide a conveyer which can eliminate a need of mechanical structure portion and prevent generation of noise and trouble due to its structure by exciting progressive wave by ultrasonic vibration on the surface of an elastic body, and bringing a body into contact with the progressive wave on the elastic body surface. CONSTITUTION:Ultrasonic vibrators 2 are installed on the inner surface or the lower outer surface of a conveyer main body 1 comprising a belt-like elastic body formed like an endless oval, for example, at spaces half the vibration wavelength. In this arrangement, when the vibrators 2 are driven to apply vibration to the conveyer main body 1 in direction of bending, elastic wave due to bending vibration is generated, so that by the ratio of the longitudinal displacement to the transversal displacement in a certain material point on the surface of the main body 1, the material point is caused to make elliptic motion and progress. Accordingly, a body is brought into contact with the material point to be conveyed through frictional force. | ||||||
