Abstract  In order to meet the demand of printing market for high-speed, high-quality and high-efficiency 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.

LYP1050轮转胶印机控制系统设计

为满足印刷市场对高速、高质量及高效率胶印机的需求，设计了一种LYP1050轮转胶印机控制系统。首先，采用汇川AC810运动控制器作为主控制器，以汇川IT6000系列触摸屏作为人机交互界面，结合伺服驱动单元，搭建了LYP1050轮转胶印机控制系统的硬件平台。然后，提出了LYP1050轮转胶印机的多轴同步控制、闭环速度和收卷锥度张力控制以及自动套色控制方法，同时，对LYP1050轮转胶印机控制系统的下位机程序和人机交互界面进行设计。最后，通过采集LYP1050轮转胶印机样机实际运行时的套色误差来验证所设计的控制系统的可靠性。试验结果表明：该轮转胶印机的套色精度可控制在±0.05 mm内，符合套色要求。所设计的控制系统安全可靠，同步性较好，套色精度高，故障率低，具有广泛的通用性，可为同类型轮转胶印机控制系统的设计提供参考。
