基于 PLC 的自动化立体仓库摘要: 随着企业现代生产规模的不断扩大，立体仓库已成为生产物流系统中一个重要而不可缺少的环节，堆垛机是其关键设备。本文的思想是将整个仓库划分为多个区域，然后将每个区域划分为真实和虚拟的位置。结合虚拟和真实位置，根据货物进出仓库的频率，将货物存储在相应的位置，以提高操作效率。本文所描述的系统由先进的 PLC 控制器和变频器驱动的闭环交流伺服系统控制。光电传感器用于检测堆料机的位置。分析了堆垛机的工作过程。研究了堆垛机的运动控制和位置检测方法。实现了堆垛机的定位方案。通过上位机系统对 PLC 的运行进行监控，对货位信息进行处理，解决了堆垛机对货物访问路径的优化问题。最后，采用 PLC 对堆垛机系统进行控制，实现本文设计的堆垛机系统的在线、自动、手动和维护四种控制模式，以及进出站货物运输三种模式。最后，给出了上位机监控系统的程序实例和主要功能。通过实验室模拟运行，堆料机系统运行平稳，定位准确，安全可靠地满足设计要求。关键词:自动化立体仓库;堆垛机;货位优化;监控系统;PLCAutomated Stereo Warehouse Based on PLCAbsrtact: With the continuous expansion of modern production scale of enterprises, three-dimensional warehouse has become an important and indispensable link in production logistics system, and stacker is its key equipment. The idea of this paper is to divide the whole warehouse into several areas, and then divide each area into real and virtual locations. Combining virtual and real locations, according to the frequencies of goods entering and leaving the warehouse, the goods are stored in the corresponding locations to improve operation efficiency. The system described in this paper is controlled by advanced PLC controller and closed-loop AC servo system driven by frequency converter. The photoelectric sensor is used to detect the position of the stacker. The working process of the stacker is analyzed. The movement control and location detection methods of the stacker are studied. The positioning scheme of the...
