At present, the sorting and labeling of round fruits in peasant household is still depending on the manpower with low efficiency. This paper presents a solution for the integration of sorting and labeling. An automatic sorting and labelling machine is designed for selecting and labeling the size of round fruit in peasant household. This machine is mainly composed of roller type sorting device and automatic labelling device, which can automatically complete the sorting and labeling of round fruit. The optimal parameters of each part were determined through the elaboration of the whole structure and the working principle of each part and the theoretical calculation of the main element parameters. Test results show that the prototype sorting and labeling integration work mode can automatically complete the sorting and labeling work, with the fruit sorting accuracy rate of 97%, the labeling the percent of pass of up to 98.7%, sorting time of about 1/2 compared with the workers. The design cost of the prototype is much lower than the commercial sorting and labeling machine, which provides a new innovative technology for the automatic sorting and labeling of small round fruits.
