目的 为了解决传统刨切机自动化程度不高、刨切精度及效率低的问题，设计小径木双面连续式纵向刨切机的控制系统。方法 对小径木双面连续式纵向刨切机加工工艺进行分析，制定控制系统设计的要求。根据刨切小径木的控制系统的需求进行分析，完成控制系统资源的需求统计和所需电器元件的选择，设计小径木双面连续式纵向刨切机的PLC控制程序和操作界面，以1次刨切循环为例，对程序及操作界面进行说明介绍。结果 控制系统运行后，大大提高了小径木双面连续式纵向刨切机的自动化程度以及精度，可使进给精度达到0.026 mm。结论 基于PLC的小径木双面连续式纵向刨切机的控制系统可以达到提高刨切机自动化程度及精度的要求，具有很大的经济效益。

In order to solve the problems that traditional veneer slicer has low automation degree，low sliced precision and low efficiency, the work designs the control system of sides continuous veneer slicer. The processing technology of slicing small-diameter wood for sides continuous veneer slicer was firstly analyzed, and then the control system design requirements were formulated. The control system resource demand statistics were completed and the electrical components were selected according to the control system demand and the working process of slicing small-diameter wood. The PLC control program and the interface of sides continuous veneer slicer were designed and the program and interface were introduced by taking a sliced veneer cycle as example. After the operation of the control system, the automation degree and precision of the sides continuous veneer slicer for small-diameter wood could be greatly improved, and the feed accuracy reached 0.026 mm. In conclusion, the control system of the sides continuous veneer slicer for small-diameter wood based on PLC can meet the requirements of improving the degree of veneer slicer’s automation and accuracy and has great economic benefit.
