FIELD: proportioning and packing technology. SUBSTANCE: device has a proportioning module of n, conveying paths (1≅ n≅ 16), which provided with ncollecting bins. Portion Vof section nof collecting binsis made integral with pockets in lower part in quantity of nand selected in relation to total volume of Vof bin within limits of. Each conveying path is provided with coarse and/or fine mode of operation with adjustable cross-section are. Minimal and maximal cross-sectional areas Sand Sfor passing the product being handled are related as. Relation of adjustable areas Sfor coarse mode of operation and Sfor fine mode is selected within the limits of. Relation volume Vof working surface of weighing proportioner as to volumes Vand Vis selected within. Minimal and maximal areas of passing the product Sand Sfrom working space of weighing proportions are taken within the limits of. Volume Vof a package relates to the volume of working space Vas. Control unit for the device has a weight measuring apparatus, module for measurement of proportioning process parameters and facilities for processing of control signals and forming of operating commands, instrument for measuring the discharged proportioner capacity. Inlet and outlet of proportioner are connected respectively to weight measuring apparatus and to operating mechanisms of conveying paths. Control unit also has a memory for storing the data of previous measurements with its inlet connected to weight measuring apparatus, unit for product dose correction at several points with passages of coarse and fine proportioning modes, and unit for measurements of minimal and maximal angles α and b of positioning of operating mechanisms for package length adjustment and their values are interrelated as, where a-experimental coefficient (0,3 ≅ a≅ 4,2). EFFECT: high efficiency. 2 cl, 3 dwg, 1 tbl |
