Sažetak

The new solutions of a vibratory conveyor utilised for transporting - with variable velocities - loose materials or objects of small dimensions, were analysed in this study. This vibratory conveyor has a possibility of immediate suspension of the feed material flow without the necessity of the drive switching off. Up to the present, this type of solution was realised by means of an expensive electromagnetic exciter. The conveyor analysed in this paper is induced to vibration by a significantly cheaper and often employed electro-vibrator. Such solution has not been applied for suspension of transport so far in the industry, while it is essential at discontinuous operations of the conveyor, especially at the feed dosage. This solution allows to design cheap production lines within which the conveyor will realise not only continuous transport. Values of amplitudes of the trough and applied eliminator in dependence of the excitation frequency were analytically determined. The results were confirmed by the simulation analysis of the device. The whole model of the conveyor together with the loose feed was investigated by the simulation analysis of the feed transport velocity in dependence of the excitation frequency of the system. The obtained results are very satisfactory and provide the basis for further investigation of the conveyor in a laboratory set-up.
