Relevance. It is justified by the necessity to confirm the operability of the algorithm of accurate movement of the selected wood sorting to the corresponding storage bunker in the technological process of roundwood sorting at winter warehouses of timber processing companies to solve scientific and engineering problems both at present and in the future. Aim. To investigate the process of moving piece load on the physical model of longitudinal chain or belt conveyor, providing scaled reduction of positioning error. When sorting roundwood on chain longitudinal conveyors of considerable length, there is an error of movement of the selected roundwood sort to the place of discharge into the accumulator, which increases in proportion to the length of the sorting line. At present, conveyors of limited length are used. The accumulators are located on both sides of the conveyor. This reduces the transport error. Sometimes the sorting yard does not allow placing a short conveyor on it or there is a considerable amount of assortments. In this case, it is necessary to use a conveyor of considerable length. The paper proposes a new method of sorting roundwood on longitudinal chain conveyors of considerable length. This reduces the tracking error of the movement of the assortment. Optoelectronic sensors of angular displacements of the leading and driven shafts of the belt conveyor are used as sensors of angular displacements of the shaft. Methods. Physical modelling, information-static processing methods. Results and conclusions. The authors have carried out the analysis of the structure of the physical similarity stand of the longitudinal conveyor; sensors of the technological process, namely, angular frequency of rotation; software and hardware means of processing the obtained information to minimize the error of transporting piece cargo on the conveyor belt. The results of the study confirm the possibility of practical application of the device for operation on longitudinal conveyors.
