摘　　要：为了满足高速卷筒纸胶印机不停机更换纸卷的需求,研究了高速自动接纸系统的工艺要求,提出了以纸架旋转、纸卷圆周加速、海绵辊粘接、裁刀切断4个基本功能模块为主体的解决方案,并分析了相应的气动控制系统的组成原理和控制方法,利用FluidSim仿真软件进行气动控制系统的仿真设计和调试,经过仿真设计提出了一套适合卷筒纸胶印机高速接纸系统的气动控制解决方案和设计方法,为进一步研究纸卷运行状态控制提供了理论基础。Flying splicer is a key component of web-fed offset presses for automatically replacing the exhausting web roll with a new one without stopping the machine.The systematic solution of the web splicer is brought out based on the researching of the process requirement of the automatic web changing,which is mainly composed by reel arm rotating,circumferential acceleration of the web roll,pasting by the foam roller and cutting the exhausted web modules.The composition and working principle of pneumatic controlling mechanism for driving the flying splicer is analyzed according to the processing principle of automatic web alternation.By using the software FluidSim,the pneumatic sequential operation controlling circuitry with multi-cylinders for driving the flying splicer is designed,in which the air cylinders cooperates to accelerate the new reel to the circumferential velocity of the expiring web,paste the adhesive end of the new reel with the expiring web,and cut the remaining piece of expired web off.A system scheme and designing method of the pneumatic controlling system suitable for automatic web roll change on high speed offset printing presses is brought out and supplied the theoretic basis for the further researching of the controlling method for the running status of the web roll.
