A Method to Design Vibratory Bowl Feeder by Using Numerical Simulation Analysis

In the modern industry, vibratory bowl feeders - VBF have been widely used to feed small and light parts such as USB caps. In this method, the bowl's vibration, which caused by forced vibration and the friction between parts and track, helps convey the parts out of the feeder along the track. However, ensuring that the directional requirements before going out works correctly depends entirely on the sorting bowl. For different types of parts, sorting bowl design is different. This paper presents a digital simulation study, using the multibody dynamics analysis on the Adams View platform, to analyze the movements status of parts on the sorting bowl. And it uses modal analysis on the ANSYS Workbench platform to determine the natural-vibration frequency of the system. With the results, we could identify optimum parameters, bowl's structure, the sorting track, mounting adapter and suspension system for a stable operating system. Then an experiment is conducted to validate the results.
