Vibration loading devices are widely used in various branches of mechanical engineering to load piece blanks of automatic machines and automatic lines as well as robotic systems, automated systems and flexible automated production. Vibration devices for transportation and loading of miniature, small and medium-sized products are the most widely used. In the study of vibration transport, one of the most important issues is the study of the dependence of the average transport speed on the parameters of the oscillation of the carrier tray. It is most convenient to conduct a study in dimensionless quantities when expressing the speed of transportation through the speed coefficient, which shows how much the real speed of the part is close to the maximum speed of the transporting surface. For vibration conveyors and vibratory feeders with non-separable transportation parts using modes that are implemented mainly elliptical or asymmetric longitudinal vibrations of the bearing plane. Asymmetric laws of motion of vibration conveyors provide the highest performance in a non-invasive mode of movement of billets, but such conveyors have found a very limited distribution due to the complexity of the implementation of asymmetric vibrations by simple means. To implement the asymmetric laws of oscillation of the working body and thereby increase the speed coefficient used as power sources generators asymmetric types of oscillations, which have a very high cost. Modern production involves the creation of new models of machines with high technical and economic indicators, therefore, improving the efficiency of existing equipment and the development of new schemes of machines is an important task for designers and manufacturers of technological equipment, as the minimum improvement of its technological and operational performance can lead to a tangible economic effect. To solve this problem, the authors developed a new design of vibration hopper feeder, which carries out the transportation of products in the mode without throwing with an asymmetric law of oscillation of the carrier tray when connected directly to the AC network without using an asymmetric pulse generator and conducted an experimental study of its design to determine the speed coefficient during vibration transportation.
