Abstract(in English) | The authors already have proposed new powder transportation device using ultrasonic vibration. The proposed powder transportation device consists of a unimorph vibration plate with a piezoelectric element. In the excitation of the flexural mode, the powder spreaded on the plate is gathered at the nodal point. Then, a block of powder at the nodal point is shifted by driving another resonance flexural mode. The amount of the powder gathered is determined by the wave length of the flexural mode. And hence, supplying amount control is achieved by wavelength of flexural vibration mode using the proposed method. However, it is difficult to improve the transportation amount accuracy in the previous transportation device because the supplying point is an anti-node of the flexural mode. In this report, in order to transport high accurately, the powder transportation device that has the vibration plate with closed wall was made. And the transportation amount characteristic was examined. In this device the hole structure is made at the position of 10mm from the end of the vibration plate, and the powder is supplied from this position. Additionally, the guide was made to avoid supplying the powder from the end of the vibration plate. As a result, the improvement of the transportation amount accuracy was confirmed. |
