A Study on the Integrated Modeling of Decoupled Vibratory Feeder

Abstract:

Vibratory feeders play an important role in automated systems and the decoupled vibratory feeder is a novel design which is excited in two different directions. The research on decoupled vibratory feeder concentrates on the modeling, the control system and structural optimization. The aim of this work is to focus on the integrated modeling of the decoupled vibratory feeder. The integrated modeling consists of the mechanic modeling, the electrical modeling and the control strategy. The modeling of all modules including the PID control, the power amplifier, the electromagnet, the feeder, the part motion and the feedback are discussed to reveal the relation between the input signal and the part motion. The block diagram of the integrated modeling of the whole system programmed with MATLAB is given in this paper. A deeper understanding of the decoupled vibratory feeder can be obtained by the integrated modeling to optimize the structural design and improve the conveying efficiency.
