壳芯机单机或联线自动控制,一般采用有触点继电器控制系统。但由于系统复杂,再加之工作环境温度高、粉尘多、振动大、动作频繁,致使其控制可靠性低。同时,也难于适应壳芯制芯工艺变更的要求。为此,我们将 GE—1PC 可编程序控制器(简称 PC 控制器),应用到壳芯机的电气控制系统中,收到满意的使用 Shell core machine alone or in line with automatic control, the general use of contact relay control system. However, due to the complexity of the system, coupled with the high temperature of the working environment, dust, vibration, frequent movements, resulting in low control reliability. At the same time, it is difficult to adapt to the shell core making process change requirements. To this end, we will GE-1PC programmable logic controller (PC controller for short), applied to the shell core electrical control system, received satisfactory use
