Abstract: In order to solve the slow process of standardization and automation of breakbulk cargo, low efficiency of sorting and loading and unloading and the safety problems caused by manual loading and unloading, to promote the digital transformation of transport sorting and loading and unloading and to realize the construction of smart ports, this paper takes the long strip breakbulk cargo with standardized transport scale as the object of research, and with reference to the standard 40-foot containers and the dimensional structure of the existing general cargo loading and unloading equipment, designs an intelligent equipment and integrated system from storing to loading and unloading and sorting. Through numerical calculation, application of CAD composition and three-dimensional model for intelligent sorting system structure analysis, and with the standardized design of the operation process, this paper proposes the intelligent sorting system realization scheme that can be applied to the containerization of the long strip breakbulk cargo. The results of the simulation show that the containerization of long strip breakbulk cargo can increase the land utilization rate by 1.6-2.4 times, and the smart picking system can reduce the manpower requirement by 5 times and increase the loading and unloading efficiency by 2.4 times. The design of the smart sorting system breaks the limit of manual operation capacity and meets the demand for efficiency during peak production operation hours. The system implementation plan also provides a reference direction for the development of smart ports for breakbulk cargo.
