The packing robot in China is less developed than western countries at present. For the demand of packaging in food and beverage industry, the integrated case packer based on robot is developed and used in production line. The scheme and layout of the system with seven subsystems is proposed. With the identification of the critical path, the process is analyzed to improve the efficiency of the integrated case packer. Finally, path planning and motion parameters of packing operation are optimized and its experimental research is carried out, which verifies the feasibility of system design. The equipment is applied in Hangzhou WaHaha Group Co., Ltd. with a desired result.
