Study on Progressive Wave Type Feeding Micromechanism for Small Visco-flabby Bodies

对于超薄叶片和粘性较松软的物料，在进料时，用手指和其他拾取工具搬运时损坏，并在进料时粘在卡车表面。在表面产生的递进波对材料产生一种漂浮状态，并将其传递到表面，就好像它们被水冲走一样。为了实现这一思想，在表面产生椭圆振动。第一次试验的装置是由一组可以相互独立调节相位的组合椭圆振子平行排列而成的。拉伸后的弹性膜在表面上弯曲。它由环形偏转谐振器和倒摆谐振器组成。很明显，在挠曲中第二模态和弯曲中第一模态的组合适合于进给运动。合理化谐振器的设计和制造是在一个指导下确定的形状，考虑条件，平面上的上板和振幅控制的侧面成员由一个微晶型PZT驱动的环。在给料的基础实验中，发现给料能力取决于物料表面的湿润度和光滑度。通过在激励信号上叠加高频分量来提高平滑度。金属叶片，镍和非晶，已经成功地以椭圆振动的馈送表面上的谐振器列。

In the case of feeding for ultrathin leaves and visco flabby materials, they are damaged by handling with fingers and other picking up tools, and paste on a truck surface in feeding. Progressive wave generated on the surface is yielded to a state of floating to the materials and conveys them on the surface as if they are washed away by the water. Elliptic vibration is generated on the surface for realization of the idea. This apparatus for the firsttrial is formed by a parallel arrangement train of combined elliptic vibrators which can be independently adjusted a phase of each other. A stretched elastic membrance is convered on the surface. It is composed of a loop shaped deflective resonator and a resonator as a reversed pendulum. It become clear that combination of a second mode in deflection and a first mode in bending suitable to feeding motion. The rationalized resonator is designed and manufacutured under a guide for determination of the shape considered the conditions, flatness over the upper plate and amplitude control of the side member actuated by a bymorph type PZT in the loop.In the basic experiment for feeding it was appeared that feeding ability depends on wetting and smoothness on the surface. Smoothness is promoted by superposition of the high frequency component to the excitation signal. The metal leaves, nikel and amorphous, have been succeeded in feeding with an eliptic veibration on the feeding surface over the resonator train.
