堆垛机柔性载货台模块化设计 摘要 随着我国市场经济制度的逐渐完善以及互联网技术的大规模应用，市场竞争十分激烈，对于企业而言，土地成本和人力资源成本都在不断增长，越来越多的企业为提高生产效率、节约生产成本，选择重点投资生产制造及物流派送系统的自动化。自动化立体仓库具有提高仓储空间利用率、提高企业管理水平等优点，被广泛应用于生产加工、医药、烟草、物流配送等企业。 堆垛机通常用来存取尺寸规格相对固定的货物。但物流配送等行业中，堆垛机往往需要存取尺寸规格不一的货物。传统的堆垛机需要配合垛板来实现货物的存取，不仅造成空间的浪费，同时降低了生产效率。本文针对这种普遍存在的问题，尝试性地设计一种新型的具有较高柔性的载货台，可以灵活调节货叉的间距，完场尺寸规格不同的货物的存龋本课题运用模块化设计方法，对堆垛机载货台进行了模块划分，给出了详细的设计思路以及有限元分析以验证设计的可行性。设计出了可以较好地解决存取尺寸规格不一货物的问题的柔性载货台。对于企业解决仓储物流中所遇到的传统堆垛机在存取尺寸规格浮动较大的小型货物时，存在的存取困难甚至无法存取的情况，具有优秀的实用价值。 关键词:自动化立体仓库，柔性载货台，模块化设计，有限元分析 MODULAR DESIGN OF THE FLEXIBLELOADING PLATFORM OF THE STACKING CRANE ABSTRACT With the rapid developme
