基于PLC的扁肉皮自动生产线监控系统设计

摘要

设计了基于PLC和可编程终端的扁肉皮自动化生产线监控系统.该生产线主要由3台扁肉皮压皮电机和1台叠皮电机以及若干台撒粉电机构成,光电传感器实时检测扁肉皮的松紧程度,然后通过变频器实现对各台压皮电机的连续调速控制.此外,可编程终端可以方便地设定控制系统的相关参数、显示生产过程中的实时数据,大大提高了扁肉皮的生产效率.系统还对压皮电机和叠皮电机设置有故障报警指示,保证生产过程的安全性.%This paper designs an automatic flat skin production line monitoring system with PLC and programmable terminal.The line consists of three flat skin leather pressing motors and one stacked leather motor and the number of dusting motors.Photoelectric sensors are used to detect the real-time flat skin tightness,and continuously control speed of motors with the transformer.In addition,the programmable terminal can easily be used to set the parameters of the control system and display the production process real-time data,thus,greatly improving production efficiency of flat skin.The system is also equipped with the fault alarm indicators for pressed and stacked leather motors to ensure the safety of the production process.
