    摘要:

    目的:解决中国鲜果人工分选准确率低、效率低、劳动强度大和生产成本高的问题。方法:基于果品质量分类法研制一款新型动态称重式果品分选机,该机具基于高精度称重单元采集的果品质量,然后经信号处理模块和PLC协同对采集的数据进行处理并控制起弹器,根据水果质量实现果品的分级。该机具可连续实现果品(直径≤126 mm)的上料、称重、分选作业。结果:当分选效率分别为18 327,14 400,10 473个/h时,分选准确率平均值分别为95.31%,96.12%,97.13%,损伤率分别为1.09%,1.11%,1.15%;水果分选速度显著影响分选的准确率,对果品损伤率影响不明显。结论:该新型动态称重式果品分选机能够在保持分选准确率>95%的前提下有效提升果品分选的效率且对果品损伤较小。

    Abstract:

    Objective: To solve the problems of low accuracy and low efficiency, high labor intensity and high production cost of fresh fruit manual sorting in China. Methods: A new dynamic weighing type fruit sorting machine was developed based on the fruit weight classification method. This machine operated by initially collecting the weight of fruit through a high-precision weighing unit. The data collected was then processed in conjunction with a signal processing module and a Programmable Logic Controller (PLC). The processed data controlled an actuator, specifically a launcher, to execute the sorting based on the fruit's weight. This machine was capable of continuously performing loading, weighing (diameter ≤126 mm). Results: When the separation efficiency was 18 327, 14 400, 10 473 PCS/h, the average separation accuracy was 95.31%, 96.12%, 97.13%, and the damage rate was 1.09%, 1.11%, 1.15%, respectively. Fruit sorting speed significantly affected the sorting accuracy, but had no significant effect on fruit damage rate. Conclusion: The new dynamic weighing type fruit sorting machine can effectively improve the efficiency of fruit sorting and reduce the damage to fruit under the premise of keeping the sorting accuracy >95%.
