基于S7-1500 PLC和工业机器人的小方坯自动喷号系统设计

Design of Small Billet Automatic Number Spraying System Based on S7-1500 PLC and Industrial Robot

小方坯喷号作为炼钢厂产品输出上报的重要工序,是连接炼钢和轧钢的中间环节,用工业机器人代替人工进行自动化设计改造,是推进智慧制造的重要行动。本文小方坯自动喷号系统以西门子S7-1500系列可编程控制器(programonable logic controller,PLC)为控制核心,ABB工业机器人为自动喷号执行部件,对接企业MES(manufacturing execution system)系统,组建三层集散控制系统,实现对小方坯自动喷号和生产数据统计上报的功能。高效精准的网络传输和智能化人机界面设计,使得小方坯自动喷号系统实现集中管理、分散控制,年成功喷号率达98%以上,生产效率得到大幅提高。

As an important process of product output reporting in steel mills,small billet spray number is an intermediate link connecting steelmaking and rolling.It is an important action to promote intelligent manufacturing to use industrial robots instead of manual automation design and transformation.The small bille tautomatic number spraying system takes Siemens S7-1500 series programmable logic controller(PLC)as the control core,and ABB industrial robot as the executive part of automatic number spraying.It connects with the manufacturing execution system(MES)of the enterprise and establishes a three-layer distributed control system to realize the function of automatic number spraying of small billet and production data statistics and reporting.Efficient and accurate network transmission and intelligent human-machine interface design make the billet automatic number spraying system realize centralized management and decentralized control,the annual successful number spraying rate is more than 98%,and the production efficiency has been greatly improved.
