The control system of the automatic line is mainly used to ensure that the machine tool, workpiece transfer system and auxiliary equipment in the line work normally according to the specified work cycle and interlocking requirements, and is equipped with a fault finding device and a signal device. In order to meet the requirements of debugging and normal operation of the automatic line, the control system has three working states: adjustment, semi-automatic and automatic. In the adjustment state, it can be manually operated and adjusted to realize the various actions of a single device; in the semi-automatic state, the single-cycle work of a single device can be realized; in the automatic state, the automatic line can work continuously.
The control system has a "pre-stop" control function. When the automatic line needs to stop under normal working conditions, it can stop after completing a working cycle and the relevant moving parts of each machine tool return to the original position. Other auxiliary equipment of the automatic line is set according to the process needs and the degree of automation, such as the automatic inspection device of the cleaning machine workpiece, the automatic tool changer, the automatic chip holding system and the centralized cooling system. In order to improve the productivity of the automatic line, the working reliability of the automatic line must be guaranteed. The main factors affecting the reliability of automatic line work are the stability of processing quality and the reliability of equipment work. The development direction of automatic line is mainly to improve productivity and increase versatility and flexibility. In order to meet the needs of multi-variety production, an adjustable automatic line that can be adjusted quickly will be developed.
