目的 基于慧鱼模型设计一种多品种水果包装系统，旨在对不同品种的水果进行分拣、称量、贴标和码放。方法 设计水果包装系统的升降、储物、分拣、装箱、贴标等机构，用慧鱼创意组合模型搭建水果包装系统的实物模型。采用图形化编程软件ROBO Pro开发水果包装系统的控制程序，并进行模拟仿真。结果 仿真结果表明，该水果包装系统可分拣模型直径为4~14 mm的球形或椭圆形水果，适用于樱桃、桔子、枣等球形水果的分拣与包装。结论 该水果包装系统分拣效率较高，能实现多种水果的自动分拣、包装。

The work aims to design the multi-species fruit packaging system based on Fischertechnik model, for the purpose of sorting, weighing, labeling and stacking up different varieties of fruit. The mechanisms for lifting, storage, sorting, packaging and labeling of fruit packaging system were designed. The physical model of the fruit packaging system was established based on the Fischertechnik model of creativity combination. The graphical programming software ROBO Pro was used to develop a fruit packaging system control program and the simulation thereof was conducted. The simulation results showed that, the fruit packaging system could sort the fruit with a diameter of 4~14 mm of spherical or oval shape, which was suitable for the sorting and packaging of such fruit as cherry, orange, jujube and other fruit of spherical shape. With higher sorting efficiency, the fruit packaging system can realize the automatic sorting and packaging of a variety of fruits.
