Study of the dynamic model of the oscillating system of vibratory feeders with an elliptical trajectory of the movement of the working body

Vibrating feed bins with electromagnetic drive are widely used in the automation of production processes in mechanical engineering and instrument engineering. They are used for feeding miniature, small, or medium-sized parts to automated production equipment. These parts must be located in a certain stable position, that is, oriented in space, when using these feeders to feed component parts to the assembly position in assembly machines. Different means of orientation may be applied, which are directly located in the bunkers of these devices, in this case. The parts must be transported without sensitive tossing on trays of vibratory feeders for reliable operation of such orientation devices. A vibratory feeders with an elliptical trajectory of vibrations of the working body should be used in this case. A vibrating feeder with independent oscillations can be used in such a case. Vertical and horizontal component oscillations are excited by separate drives in it. It is necessary to apply a device for shifting phases in the power supply system of vibration drives to obtain elliptical oscillations. However, existing designs of vibrobunker feeders with an independent oscillation system have a number of significant disadvantages. They require the presence of independent vibrators: an axial vibrator to excite vertical vibrations and two or more tangential vibrators to excite horizontal (angular) vibrations. In addition, it is necessary to have a device for shifting the phases between them. Therefore, there was a need to create a new design of a vibrating bunker feeder with a system of elliptical oscillations, which will not have the listed disadvantages. Such a vibrating hopper feeder was developed and an experimental sample of this design was made. However, for the successful implementation of such feeders, a preliminary calculation of the parameters of their oscillating system is required, the methodology of which differs from the existing one. In the presented work, a mathematical study of the dynamics of the oscillating system of such vibratory feeders was carried out and a calculation method for its calculation was developed.
