【摘要】：随着自动化技术的发展和生产力水平的不断提高,以往传统的生产制造模式发生了深刻的变化,同时对生产车间物料搬运作业自动化、敏捷性、柔性和准时度都提出了更深层次的需求。在柔性制造系统中,产业界经常采用自动导向小车(AGV)系统作为物料输送的主要设备和运作模式。AGV自动搬运小车代替了以往的人工拖运,既提升搬运效率,也减少了搬运风险。特别是在企业人力成本上涨已经是不争事实的今天,生产自动化成为主流趋势。企业在实施这样的物料输送方式时,必然会考虑AGV的运行时间,流量,费用,距离等因素,综合以求得最佳路径。本文考虑了在A电子公司SMT车间现有的生产物流系统与设施布局的基础上,为了满足AGV从物料仓与车间的各个装卸点之间最快时间周转的要求,应用图论的理论和采用Floyd算法对网络中任两个装卸点间的最短路径进行计算,找出符合最短路径的装卸点,以此确定物料仓的最佳位置。在此基础上,延伸探讨了AGV运行中的避碰的控制问题以及事后对此系统的量化评价方法,为设施布局决策提供理论上的依据。
[Abstract]:With the development of automation technology and the continuous improvement of productivity level, the traditional manufacturing mode has undergone profound changes, and at the same time, the automation and agility of the material handling work in the production workshop has taken place. Flexibility and punctuality present deeper requirements. In the flexible manufacturing system (FMS), the automatic guided trolley (AGV) system is often used as the main equipment and operation mode of material transportation. The AGV automatic handling dolly replaces the previous manual haulage, which not only improves the handling efficiency, but also reduces the handling risk. Especially in the enterprise human cost rise is an indisputable fact today, production automation has become the mainstream trend. When the enterprise implements this kind of material transportation mode, it must consider the running time, flow rate, cost, distance and other factors of AGV, so as to obtain the best path. In this paper, on the basis of the existing production logistics system and facility layout in SMT workshop of A Electronics Company, in order to meet the requirement of the fastest time turnover between the material warehouse and the loading and unloading points of the AGV, The theory of graph theory and Floyd algorithm are used to calculate the shortest path between any two loading and unloading points in the network to find out the loading and unloading points which accord with the shortest path and to determine the best position of the material warehouse. On this basis, the control problem of collision avoidance in the operation of AGV and the quantitative evaluation method of the system are discussed, which provides a theoretical basis for the decision-making of facility layout.
