Dynamics of a Piezoelectrically Actuated Vibratory Feeder Available to Purchase

This paper presents the development of a vibratory parts feeder driven by piezoelectric bimorph actuators. Mathematical models to describe dynamic behaviors of the piezoelectric bimorph actuator, vibratory parts feeder, and kinematics of the moving parts are formulated and numerically solved. Design factors such as the vibration amplitude, vibration frequency and vibration angle that affect the performance of the parts feeder is quantitatively investigated. Operating at the resonant vibration, the developed vibratory parts feeder achieves a high operating frequency and fine feed steps.
