Design and experiment of dynamic weighing type fruit sorting machine
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％.
