Abstract

The work includes an analysis of the accuracy of estimating the determined quantity of paper sheets on vibratory conveyors from the perspective of probability theory and mathematical statistics. A resulting formula for determining the confidence interval of measurement error was obtained. It was found that for paper with a coefficient of variation in the range of 0.52%–1.29% (with a total number of sheets of 4000), the confidence interval of error due to the weight non-uniformity of sheets exceeds the confidence interval of error due to inaccuracies in large and small weights by approximately 5 times.
