Design of Automatic Feeding Machine for Jar Sealing Based on TRIZ Theory

ABSTRACT The goal of this study was to address the inefficiencies of manual yellow wine jar sealing—characterized by high labor intensity and low productivity—by innovatively designing an automated feeding machine using TRIZ theory. We aimed to resolve technical contradictions in material handling and sealing processes while ensuring compatibility with traditional practices. Initially, the technical contradictions in the sealing and feeding process were analyzed, and a contradiction matrix was constructed to identify pertinent invention principles, including Division, Extraction, Inversion, Periodical Action, Copying, Pneumatic and Hydraulic, Changing State and Composite Materials. Based on these principles, a design scheme for the sealing and feeding machinery was developed. The optimal solution was subsequently determined through hierarchical analysis and fuzzy comprehensive evaluation. This solution has been implemented in the company's production line, achieving an average sealing time of 8 s per unit. This advancement demonstrates significant practical value and represents a novel approach to the development of automated feeding equipment for yellow wine production and sealing.
