摘　　要：目的:解决目前山核桃破壳自动化生产线控制系统自动化水平低、效率低等问题.方法:在现有山核桃破壳自动生产线的基础上,提出一种基于PLC控制技术的山核桃破壳自动化生产线控制系统.以PLC为核心完成整个山核桃破壳自动化生产线的控制,包括破壳机、风选机、破壳分离机、色选机等设备.以直径18~22mm核桃为试验对象,对样机进行了验证.结果:相比于控制系统投入前,实施控制系统后提高了山核桃破壳率和降低了核仁损伤率,直径为18~22 mm的山核桃,破壳率100%,核仁损伤率5.02%,符合生产要求.结论:基于PLC的控制技术符合核桃全自动生产线的要求.Objective:In order to solve the problems of low automation level and low efficiency of the control system in the current automated production line of hickory shell breaking.Methods:On the basis of the existing automatic production line of hickory shell breaking,a control system of hickory shell breaking automatic production line based on PLC control technology is proposed.With PLC as the core,the control of the whole hickory shell breaking automatic production line was completed,including shell breaking machine,air separator,shell breaking separator,color sorter and other equipment.The feasibility of the method was verified by testing the prototype of a walnut with a diameter of 18~22 mm.Results:Compared with that before the control system was put into operation,after the implementation of the control system,the shell breaking rate of hickory was increased and the damage rate of walnut was reduced.For hickory with a diameter of 18~22 mm,the shell breaking rate was 100%,and the damage rate of walnut was 5.02%,meeting the production requirements.Conclusion:The control technology based on PLC meets the requirements of walnut automatic production line.
