Research and Analysis on the Multi-Point Piezoelectric Vibratory Feeder of Driving Mode

Abstract:

The effect on the feeding rate and feeding stability of the multi-point piezoelectric vibratory feeder, of various factors such as driving mode, operating frequency and input signal phase difference is analyzed in detail through many experimental researches by means of the multi-point piezoelectric vibratory feeder developed by ourselves. It is found that the driving mode has critical influence on the conveying performance of the multi-point piezoelectric vibratory feeder. Symmetrical two-point, front single-point and rear single-point vibration sources, these three driving modes have their conveying performance relatively stable. However, three-point, asymmetrical two-point and bottom single-point vibration sources, these three driving modes have their feeding rate somewhat lower than that of the former three modes in the same conditions and their conveying performance is extremely unstable. In particular for the driving mode of single-point vibration source with the bottom close to the rear, conveyance of materials is almost impossible. The effect of phase difference is represented in the driving mode of multi-point vibration sources.
