This paper presents a simple approach to model an industrial vibratory bowl feeder. The vibratory feeder is a device used to separate, feed and locate automatically a variety of parts in order to speed up the process of manufacture and assemble in industry. The analytical model obtained is validated through an experimental setup, assembled in laboratory, composed by a capacitive MEMS accelerometer and a data acquisition board all integrated in a LabVIEW application. The accelerometer is composed by an integrated circuit with a capacitive cell and gives an electric signal proportional to the acceleration. This digital signal is integrated twice in order to obtain the level of displacement inside the feeder. Preliminary results show that a good agreement between the experimental and analytical models was achieved.

Key words: Vibratory bowl feeder, vibration, modeling.
