Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Design and Control System Improvement of the Form-Fill-Seal Machine for Bulk Products E.A. MAKAROVA, V.G. BARABANOV, A.M. MAKAROV, E.G. KRYLOV, N.V. KOZLOVTSEVA At food industry enterprises, bulk product packaging in flow-packs or doy-packs is mainly carried out using heat-sealable polymer PET/ PE fi lm, which has high resistance to low temperatures. For automatic equipment performing operations of prepackaging and packing bulk frozen products, design solutions have been developed that ensure the necessary tightness and strength of the formed seam of the package and a modernization of the automated control system based on a programmable controller has been proposed. An operating algorithm has been compiled and a technological program for equipment control has been written. Keywords: form-fill-seal machine, bulk product packaging, heat-sealable film, sealing thermal knife, programmable controller. DOI: 10.25791/pribor.5.2025.1581 Pp. 15-22.
