A food-packaging system consists of a box former, case packer, and taping machine. The need for food-packaging facilities is increasing, and the demand for factory automation has increased with advances in robot technology. However, current food-packaging systems suffer from incompatibility and high costs. These issues have made it difficult for many companies to adopt these systems. This vicious cycle slows the pace of industrial growth. To solve this problem, it is necessary to design an optimal machine process and modularize the machine to establish a more efficient system. In this study, the structure of the food-packaging system was simplified and made compatible, enabling companies to utilize it efficiently and reducing modularity and price.
