【摘要】：自动化立体仓库作为物流系统中的一个重要环节,它具有占地面积小,空间利用率高,存储量大,周转速度快等特点,已被广泛应用到机电、烟草、冶金、医药、食品、军队等领域。自动化立体仓库系统是集自动化技术、机械制造、计算机技术、通讯技术、智能控制技术、人因工程等技术于一体的综合自动化系统,将其作为本科教学的实训项目,可用于培养学生解决复杂工程问题的能力,适应工程教育专业认证的要求。针对电气工程及自动化本科实践教学需求,参考现有商业产品所具有的功能,本文开发了自动化立体仓库实训系统。该系统集PLC控制技术、传感器技术、步进电机位置速度控制、组态软件应用、货位分配等于一体。主要工作包括实物模型设计与加工、堆垛机控制系统设计、货位分配方案的确定与实现和监控管理系统开发,具体研究如下:1)立体仓库实物模型的设计与加工。根据设计要求货架采用25mm×25mm的万能角钢制作,设计成5层6列和5层4列共50个仓位的双排货格式货架;搬运机采用安全系数高、运行快且稳的双立柱直线型堆垛机进行设计并确定堆垛机各机构的传动方式;同时对电机、驱动器、传感器、导轨、立柱、导向轮、轴承、皮带、齿轮和齿条等元件进行了选型和安装。2)堆垛机控制系统设计。堆垛机以西门子PLC为控制器,采用相对认址方法实现水平列和垂直层的位置速度精确控制。该部分采用功能顺序设计法进行编程,将堆垛机的出入库动作分解为货台取/放货、去目标货位、前/后排取/放货、原路返回8个模块并分别编程,然后在主功能图中调用。3)货位分配方案的确定与实现。首先把仓库模型的货架分为3个区域,根据区域中货物的特点按上轻下重和周转率原则建立一个矩阵模型;然后按照该模型编写程序实现权重组合值小的能放在离货台近的区域;最终通过监控管理系统发送命令控制执行机构完成货物入库的自动存储和出库的自动拣选,使货位得到合理分配。4)监控管理系统开发。采用SIMATIC WinCC组态软件设计监控管理系统:监控系统中各种设备的动作状态;监控堆垛机的运行轨迹和停车位置;对系统中的仓位进行实时监控;通过相应权限可以手动控制执行设备的所有动作;出错报警情况及报警记录;库存管理查询;出入库货位管理等。所开发的实训系统经过实验调试,实现了设计要求的功能。该系统软件代码和硬件系统开放,为学生动手能力和创新能力的培养提供空间。
[Abstract]:As an important part of logistics system, automatic warehouse has been widely used in electromechanical, tobacco, metallurgy, medicine and food, because of its small area, high utilization rate of space, large storage capacity, fast turnover speed, etc.The military, etc.Automatic three-dimensional warehouse system is a comprehensive automation system which integrates automation technology, mechanical manufacturing, computer technology, communication technology, intelligent control technology, human factor engineering and so on. It is regarded as a practical training project in undergraduate teaching.It can be used to train students' ability to solve complex engineering problems and to meet the requirements of engineering education professional certification.According to the practical teaching requirements of electrical engineering and automation, and referring to the functions of commercial products, this paper develops an automatic three-dimensional warehouse training system.The system includes PLC control technology, sensor technology, step motor position and speed control, configuration software application, cargo allocation is equal to one body.The main work includes the design and processing of the physical model, the design of the control system of the stacker, the determination and realization of the distribution scheme of the cargo space and the development of the monitoring and management system. The detailed research is as follows: 1) the design and processing of the physical model of the stereoscopic warehouse.According to the design requirements, the shelves are made of universal angle steel of 25mm 脳 25mm. The shelves are designed into 5 layers, 6 rows and 5 layers, 4 rows and 50 positions, and the handling machine adopts high safety factor.The linear stacker running fast and steady is designed and the drive mode of each mechanism of the stacker is determined. At the same time, the motor, driver, sensor, guide rail, pillar, guide wheel, bearing, belt,Gear and rack are selected and installed. 2) Stacker control system is designed.Using Siemens PLC as controller, the stacker uses relative addressing method to control the position and velocity of horizontal and vertical layers.This part uses the function sequence design method to program, decomposes the stacker's out and out storehouse action into the cargo platform fetching / discharging, goes to the target cargo position, the front / back row fetching / discharging, the original route returns 8 modules and respectively programming,Then call. 3 in the main function diagram.First, the shelf of the warehouse model is divided into three regions, and a matrix model is established according to the principle of top light weight and turnover rate according to the characteristics of goods in the area.Then, according to the model, the program is written to realize that the weight combination value is small and can be placed in the area near the cargo platform; finally, the automatic storage of goods and the automatic picking out of the warehouse can be completed by sending commands from the monitoring and management system to control the executing agencies.The development of the monitoring and management system for the reasonable allocation of cargo space. 4).SIMATIC WinCC configuration software is used to design the monitoring management system: monitoring the movement status of various equipments in the system, monitoring the running track and parking position of the stacker, monitoring the positions in the system in real time.Through the appropriate authority can manually control the execution of all the equipment action; error alarm and alarm record; inventory management inquiry; incoming and outgoing cargo management and so on.The practical training system has been tested and debugged, and the function of the design requirement has been realized.The software code and hardware system of the system are open to provide space for the cultivation of students' practical ability and innovation ability.
