摘要
由于铸造车间的托架回送线无法连续自动运行、电机烧毁故障频发等严重制约了外模造型生产节拍。通过对PLC程序的修改来改变系统控制原理,由原设计的光电计数控制方式改进为计时控制方式;将托辊驱动的减速系统由内置式改为外置式,同时增大驱动电机功率;对原分段托辊进行拆分重组等。改进后,托架回送自动运行平稳可靠,故障率大大降低,满足了外模的节拍化生产。
It is to solve the problem that not well-organized molding production caused by incapable constant running of shelf loopback line and frequent errors of electric motor. The system control principle has been changed via revising the PLC program, with the timing control mode instead of oringinal designed photoelectric counting control mode and the built-in mode of deceleration system of supporting rollers has been changed into external one. Meanwhile the power output of driving motor has been increased and the supporting rollers have been re- arranged. With these the automatic loopback line has run steadily and reliably with failure rate decreased greatly and molding beat production achieved.
