LYP1050轮转胶印机控制系统设计

In order to meet the demand of printing market for high-speed, high-quality and highefficiency offset presses, a LYP1050 rotary offset press control system is designed. Firstly, taking the Inovance AC810 motion controller as the main controller and the Inovance IT6000 series touch screen as the human-computer interaction interface, the hardware platform of the LYP1050 rotary offset press control system was built by combining the servo drive unit. Then, the methods including the multi-axis synchronization control, the tension control of closed-loop speed and winding taper and the automatic registration control for the LYP1050 rotary offset press were proposed;at the same time, the lower computer program and human-computer interaction interface of the LYP1050 rotary offset press control system were designed. Finally, the reliability of the designed control system was verified by collecting the registration error of the LYP1050 rotary offset press prototype during actual operation. The test results showed that the registration accuracy of this rotary offset press could be controlled within ±0.05 mm, which met the registration requirements. The designed control system is safe and reliable, with good synchronization, high color registration accuracy, low failure rate, and wide versatility, which can provide references for the design of the similar rotary offset press control system. © 2021.

基于STM32的遥控墨斗系统设计

目的针对国内胶印机数字化供墨系统墨量精确调节不足的问题,分析现有供墨系统的优缺点,提出一种基于STM32的遥控墨斗系统设计方案。方法采用分区独立控制墨键开度的墨斗机械结构,以STM32F103单片机为主控制器构建墨键电机驱动硬件系统,采用6位拨码开关选址区分不同的驱动板,对磁编码器输出脉冲反馈计数实现墨键位置控制;设计操作台面板按键及显示单元,将墨键位置调节分为0～99分位,系统间采用CAN总线通讯方式,操作台面板和上位机监控界面实时显示墨键位置及状态信息。结果实验结果表明,遥控墨斗系统调节墨键开度范围为0.05～0.6mm,墨键定位精度为5μm,且重复定位精度良好。结论基于STM32的遥控墨斗系统实现了胶印机印刷过程中墨量的精确调节,且运行稳定,满足当前胶印机数字化供墨要求,具有较大的应用价值。
