摘　　要：根据纸箱粘箱中对喷胶精度和速度的要求以及热熔胶的温度特性,利用PLC替代传统的继电器接触器控制系统,设计一种基于三菱FX1N-40MR的适用于纸箱封箱的PLC控制喷胶系统,给出系统的构成及控制的实现方法。在分析影响喷胶速度与精度控制因素的基础上,利用最小二乘法消除因喷胶头控制电磁阀滞后开闭对喷胶准确度的影响,使系统可实现单个纸箱多个方位的同时精确喷胶。The precision and velocity of glue - spraying for carton encapsulation are analysed, and the temperature characteristic of hot melt glue is also studied. For a substitute of traditional relay- contactor system,a spray- glue system for carton is designed to meet the requirement based on MITSUBISHI PLC FX1N-40MR, the structure and method of control system are described subsequently. In the foundation of analysing precision and velocity influencing factors, the least square method is used to eliminate the influence of electromagnetic valve hysteresis, then the system can relize the exact glue - spraying for a carton more than one orientation simultaneously.
