The new vibratory conveyor destined for the accurate dosing of materials was investigated in the present work. The possibilities of the system to transport materials in the circum-resonant zone were tested analytically, as well as by simulations. The optimal work point of the system, which allowed a decrease in the amplitude of eliminator vibrations on its suspension due to operations on the resonance slope, was determined. Transport velocities depending on the excitation frequency and feed mass were determined by simulations. The results were verified on the conveyor of industrial dimensions designed and built in accordance with the patent application.

Transport possibilities of the new vibratory conveyor in dependence on the excitation frequency of inertial vibrators were investigated in the hereby paper. The comprehensive model of the machine together with the loose feed material was tested. Simulations allowed to determine the dependence of the transport velocity on the excitation frequency. The time needed for a sudden stopping of the transport was also investigated. The new controlling strategy, realised by means of the excitation frequency, was proposed for situations when there is a necessity of sudden stopping of the transport.

Przedmiotem analizy jest nowe rozwiązanie przenośnika wibracyjnego o zmiennej prędkości transportowania wzdłuż długości rynny z możliwością natychmiastowego zatrzymania spływu nadawy bez konieczności wyłączenia napędu. Przenośnik służy do transportu materiałów sypkich lub przedmiotów o niewielkich wymiarach, dając możliwość nagłego zatrzymania spływu nadawy. W pracy przedstawiona jest analiza dynamiczna nowej konstrukcji. Badano drgania rynny przenośnika przy różnych częstościach wymuszenia w celu zbadania możliwości transportowych i przydatności urządzenia. Wyniki prac są bardzo zadowalające i są wstępem do dalszych badań przenośnika.

The new solution of the vibratory conveyor, of a variable transport velocity along the trough length, with the possibility of immediate arrestment of the feed material flow without the need of the drive switch-off, constitutes the subject of the analysis. This conveyor is suitable for transporting loose materials or objects of small dimensions, and provides the possibility of an abrupt stop of the feed flow. The dynamic analysis of the new construction is presented in the study. Vibrations of the conveyor trough were tested at various excitation frequencies in order to investigate transport possibilities and suitability of the device. The obtained results are very promising and constitute the preliminary stage of further investigations of the conveyor.
