Assay results of the device for measuring the load of the drive roller chain of the pallet conveyor

The article substantiates the need for an experimental study of static and dynamic loads in a single-row roller chain of roller conveyors for pallets. A small-sized wireless device based on a strain gauge and Arduino boards, designed on the principle of a full bridge, has been developed to measure forces in the outer plates of the drive roller chain of a pallet conveyor, which allows data to be received at different frequencies. The tests on a full-scale stand of a drive roller conveyor for pallets with a chain transfer, carried out in a reversible mode of operation, are described. The results of a series of experimental studies consisting of preliminary calibration, static and dynamic parts are presented. To filter the obtained results from high-frequency noise, the obtained results were processed using the fast Fourier transform in Excel. We also compared the initial, averaged, and filtered results on 25 repetitions of the experiment using different data acquisition frequencies. The obtained results of measuring forces in a drive roller chain are analyzed and conclusions and recommendations for further use of the device are the most appropriate data acquisition frequencies of 12.5 Hz and 16.7 Hz are presented.
