摘要
针对钢卷上料过程中手动对中在位置测量时存在的费时和安全问题,在原有手动上料控制系统的基础上,设计开发了一套基于西门子S5 PLC的自动控制系统。通过对上料小车在垂直运行以及水平运行过程中运行轨迹的分析,提出了利用位置传感器和编码器来测量上料小车的运行位置,并通过负反馈算法自动控制上料小车油缸提升的垂直位移量和对中杆马达运行的水平位移量,自动实现了钢卷上料。在实际生产加工中对上料自动控制系统的稳定性、安全性和生产效率等方面进行了评测。实际运行结果表明,自动控制系统能稳定代替手动上料操作,避免操作工进入危险区域进行测量对中,有效提高了生产效率,消除了设备的安全隐患。
Aiming at the time-consuming and the security during the alignment process of the charging steel coil when the feeding cart＇s position was measured manually, a set of automatic control system for this charging system was developed based on the Siemens $5 series PLC to replace the old manual system. After analyzing the feeding cart＇s track on the vertical coordinate and the horizontal coordinate,a control system framework was proposed. A position transducer and an encoder were used to measure the cart＇s position and a negative feedback algorithm was used to move the the charging steel coil and the alignment pole to the correct position automatically. The stability, safety and the efficiency were tested on the actual production process. The results indicate that the automatic control system can substitute for the manual one well, and avoid workers working within the danger zone. The automatic control system improves the production efficiency and eliminate potential hazard of the equipment.
