一种在线钢坯称重装置
摘要：
本发明涉及一种在线钢坯称重装置。其技术方案是：在称重台架[7]上装有3～6个传送辊[3]及其驱动电机[5]，驱动电机[5]和制动器[10]所分别对应的电机控制继电器[25]和制动器控制继电器[26]均分别与PLC[24]的数字输出通道DO连接；2～5个电磁换向阀[20]与定位活塞杆式液压缸[9]相连的管道上均装有压力传感器[22]，每只电磁换向阀[20]和压力传感器[22]均分别与PLC[24]的数字输出通道DO和模拟输入通道AI连接；4个称重传感器[15]和红外线接收器[2]均分别与PLC[24]的模拟输入通道AI和数字输入通道DI连接；控制软件写入PLC[24]的内部存储器，组态软件写入触摸屏[23]的内部存储器。本发明具有在线称重快速、准确、冲击小和成本低的特点。
摘要（英）：

The invention relates to an on-line steel billet weighting device which has the technical scheme that a weighting rack (7) is provided with 3-6 conveying rollers (3) and a driving motor (5); a motor control relay (25) and a brake control relay (26) which are respectively corresponding to the driving motor (5) and a brake (10) are respectively connected with a digital output channel DO of a PLC (24); 2-5 electromagnetic directional valves (20) are connected with a locating piston rod type hydraulic cylinder (9) by pipelines which are provided with pressure sensors (22), and each electromagnetic directional valve (20) and each pressure sensor (22) are respectively connected with the digital output channel DO and an analogue input channel AI of the PLC (24); four weighing sensors (15) and infrared receivers (2) the analogue input channel AI and a digital input channel DI of the PLC (24); control software is written into an internal memorizer of the PLC (24), and configuration software iswritten into an internal memorizer of a touch screen (23). The line steel billet weighting device has the characteristics of rapid on-line weighting, accuracy, small impact and low cost.
