Measurement error on the number of sheets of the paper on the vibratory feeder

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.
