一种地下卷取机工作状态的控制方法
摘要：
本发明涉及一种地下卷取机工作状态的控制方法。其技术方案是在已有地下卷取机的基础上，按照电机控制装置[4]的直流调速器[12]的控制参数，设定当控制继电器[3]的电机电动状态控制触点[14]断开，控制继电器[3]的另一触点[13]闭合时夹送辊电机[5]为逆变状态，并将夹送辊电机[5]发出的电返回电网。带材尾部离开最后一架轧机后，光电传感器发出信号。控制继电器的另一触点[13]闭合，同时电机电动状态控制触点[14]断开。通过直流调速器使夹送辊电机由电动机状态转换为发电机状态。并将夹送辊电机[5]发出的电返回电网。本发明具有不改变现有设备，能提高带材的卷取质量，降低带尾对助卷辊的冲击，延长助卷辊系统的工作寿命，降低能耗的特点。
摘要（英）：

The invention relates to a method for controlling working status of a reeling machine, which comprises: basing on present underground reeling machine, according to the control parameter of the direct current speed regulator (12) of the motor control device (4), making the motor status control contact point (14) of the control relay (3), when the other contact point (13) of the control relay (3) being close, making the status of the clamp roller motor (5) as inversion status, and returning the electricity sent from the clamp roller motor (5) back to electricity network. The photoelectric sensor sends out signal when the end of band leaving the last rolling mill. The other contact point (13) of the control relay closing, the motor status control contact point (14) breaks off. The roller motor converts for electric motor status to generator status via direct current speed regulator, and returning the electricity sent from the clamp roller motor (5) back to electricity network.
