印刷设备新型纸张定位系统设计

Design of New Type Sheet Positioning System for Printing Press

主要利用纸张定位的"控制6个自由度"的基本原理,对印刷机纸张定位系统进行研究设计。研究传统纸张定位系统机械结构以及分析常出故障的原因,对前规、侧规定位部件的机械结构进行创新设计,4个红外线传感器作为前驱动力来源的步进电机的启停开关,一个光电传感器系统作为纸张侧向移动的动力来源的伺服系统的启停开关,电机通过四对压纸轮控制纸张的自由度,并增加相应独立的控制系统。分析研究结果表明:新型机电结合的定位模式较之原来传统机械式的定位方法,可以更加准确、快速地完成定位,使印刷套准在纸张定位环节的精度得到很大提高,并可以突破传统定位系统的机械结构对印刷机运转速度的限制。

The principle of controlling the degree of freedom was applied to study the sheet positioning system of printing press.Through studying mechanical structure of traditional sheet positioning system and analyzing reasons of common faults,a new type sheet positioning system was designed.Four infrared sensors were supplied to start and stop two stepping motors for controlling and moving the paper forwards and backwards,a photoelectric sensor system was used to start and stop servo-actuator system for controllin...
