烟箱分拣自动控制系统研究

目的针对烟箱的入库人工分拣强度大、效率低、误差率高等问题,结合生产实际,设计烟箱入库自动分拣控制系统。方法系统硬件由PLC、条码扫描器、光电开关、网络交换机、气缸、码盘和触摸屏等部件组成。通过读码器将读取到的条码信息经过网络传递给PLC,PLC接收条码信息并与设置的条码信息进行比较,确定烟箱类型,利用码盘产生的同步信号实现精确定位及分拣,采用脉冲区间算法降低分拣的误差率。结果该系统已经应用于卷烟厂,分拣正确率由92%提高到100%。结论系统运行可靠,减轻了分拣人员的压力,提高了生产效率和系统的可靠性。

Automatic Control System for Smoke Box Sorting

To design an automatic control system for sorting smoke boxes based on the production practice, in order to solve the problems of high labor-intensity, low efficiency, high error rate and other issues in the manual sorting of smoke boxes. The system hardware consisted of the PLC, bar-code scanners, photoelectric switches, network switch, cylinders, encoder, touch screen and other components. The barcode values read by bar-code scanners were passed through the network to the PLC, and the PLC received the barcodes and compared them to the stored barcodes to determine the smoke box types. Specific sorting and positioning were realized by the synchronization signal generated by the code disc. The sorting error rate was reduced by the pulse interval algorithm. This system was used in the cigarette factory. The correct rate of sorting was increased from 92% to 100%. The system was reliable and it reduced the working intensity of the sorting staff. The production efficiency and the system reliability were improved.
