摘　　要：针对雷管生产过程中传统的人工装管过程繁琐、工作量大、效率低的状况,研制了雷管装管机。该装置在机械结构设计的基础上,提出了一种基于PLC的模糊控制方法,该方法以装管机中的主要变量装管速度、传送带速度和推模速度为被控对象,通过模糊推理、离散计算和在线查表的模糊控制方法,以PLC控制步进电机的装管速度作为基本控制依据,以PLC控制推模速度,同时控制变频器频率,进而调节传送带的速度为被控参数,使装管机的各部分工作协调一致,并保持在最佳状态。应用结果表明,该装置不但性能可靠,而且还操作方便。For the case of cumbersome process, workload and low efficiency in the traditional manual detonator production, an detonator tubing machine was designed. The fuzzy control method based on PLC was proposed after the mechanical structure had been designed optimally. This method takes three primary variables including tubing speed, conveyor speed and push-mode speed as controlled objects to finish the fuzzy control which includes fuzzy reasoning, dis- crete computing and look-up table online. The basic idea of this method is that PLC controls the stepper motor to change the speed of tubing. The push-mode speed and frequency of the inverter are also determined by PLC, so conveyor speed can be maintained at an optimal state to make every part of the tubing machine coordinated. The application results show that this machine is not only reliable, but also easy to be operated.
