A METHOD TO DESIGN VIBRATORY BOWL FEEDER BY USING FEM MODAL ANALYSIS

This paper presented a digital simulation study, using the finite element method with modal analysis on the ANSYS Workbench platform, to determine the fundamental frequencies of the mechanical system and to affirm the design and manufacture parameters of the vibratory bowl feeders. Then an experiment was conducted to verify the results. The results suggest that the simulation model can be used to identify parameters of the bowl’s structure before the device is manufactured.

Design and Study on the Automatic Extrusion Device for Curved Chassis of Vibratory Feeder

Vibratory feeder is a device which is used to arrange small workpieces in neat rows and convey them from one place to another by vibratory feeding. It has been playing a key role in automation production. According to manufacturing equipments for the chassis of vibratory bowl feeder, this paper makes studies mainly in the followings: (1) introduces the principle of the vibratory feeder briefly, (2) the mechanical structure of the automatic extrusion device for curved chassis of vibratory feeder is designed, including frame, moulds and guiding mechanism, (3) static analysis, mould stress analysis are done by using the finite software ANSYS, (4) based on the electro-hydraulic proportional control technology, a hydraulic system is designed, (5) a control system based on STC89C52RC MCU(Micro Control Unit) is given. The problems of automatic extrusion for the curved chassis of vibratory feeder are successfully solved through the theoretical and experimental studies, which achieves the expected design goals and fills in a gap in this field in China, which brings great economic and social potential benefits and has wide application prospect.
