FMS在20世纪80年代末就已进入了实用阶段,技术已比较成熟.由于它在解决多品种、中小批量生产上比传统的加工技术有明显的经济效益,因此随着国际竞争的加剧,无论发达国家还是发展中国家都越来越重视柔性制造技术.本课题的设计内容是采用了模块化结构设计进行物料输送带的设计,优化其结构,提高生产质量与劳动生产率.需要研究的内容有: 1.带式输送机系统初步设计;

布置形式的分析确定,带速的选择;

输送带带宽、类型的选择确定;

输送带线质量的计算;

物料线质量的计算;

托辊旋转部分质量的计算. 2.带式输送机系统布置图的设计;

3.电气控制设计;

控制核心采用PLC可编程序控制器,具有自动、远控/近控两种工作方式;

电控装置和软起动装置(水平)配合,保证空载、满载工况下的软起动和软停车;

满足空载起动、重载起动.

4、柔性制造系统(FMS)的模拟设计;

关键字: 柔性制造系统、模块化结构设计、物料输送带、PLC可编程序控制器. Abstract The significance of the main research topic is to combine with the NC machine tools automatic production line characteristics of the NC machine tools and material handling equipment linked by computer to form a system to solve the medium-volume, medium-sized varieties and small batch production problems in the field, to form a so-called "flexible manufacturing system." FMS in the late 20th century,

80 had entered the practical stage, technology is more mature. Because of its many varieties in the solution, small and medium volume production than the traditional processing technology has obvious economic benefits, so as the intensification of international competition, both developed and developing countries are increasing emphasis on flexible manufacturing technology. This design content is modular belt design for material design and optimization of its structure, improve production quality and labor productivity. Need to study the contents: Preliminary design of belt conveyor system;

Layout analysis to determine, with speed selection;

belt bandwidth, the type of select OK;

conveyor line quality calculations;

material line quality calculations;

roller rotating part of the quality of the calculation. 2. Conveyor system layout design;

3. Electrical control design;

Control core with PLC programmable logic controller, with automatic, remote control / close control of two methods of work;

electronic control devices and soft-start device (horizontal) co-ordination to ensure that no-load, full load condition of the soft start and soft stop;

satisfy the no-load starting, heavy-duty starting. 4, flexible manufacturing systems (FMS) of the analog design;

Keywords: flexible manufacturing systems, modular design, material conveyor, PLC programmable logic controller. 朗读 显示对应的拉丁字符的拼音 字典 目录 摘要 绪论
