JUSTIFICATION OF THE RATIONAL PARAMETERS OF THE FRUIT FLOW DIVIDER DURING SORTING

Abstract

In this work, the experimental substantiation of the main operating parameters of the device for mechanical separation of the fruit flow during their optical sorting by a machine vision system is carried out. To conduct experimental studies, a laboratory setup was created consisting of a machine vision system with a video camera, lens and structural illumination, as well as a computing module. To obtain the regression equation, a symmetrical non-compositional Box-Behnken design was selected. The main objective of the experiment is to obtain a regression equation that will allow us to assess the influence of the influencing factors on the accuracy of separating sorted apples. The speed of the main conveyor, the angle of inclination of the carriage plate and the number of steps of holding the solenoid valve were selected as optimization factors. As a result of experimental studies, a regression equation was obtained for determining the accuracy of separating sorted fruits. Analysis of the response surfaces made it possible to establish the optimal values of the main conveyor speed = 0.41 m / s, the angle of inclination of the carriage plate = 27 degrees. and the number of steps of holding the valve by the solenoid = 93 steps, at which the sorting accuracy is more than 95%.
