【摘要】：查阅资料可以发现,国内外现有的传统提升设备的种类细分大致有三百多种。但这三百种提升设备中大部分都是散料提升机,其中可以实现包装物运输的只有八大类,不到50种。通过仔细研究可发现在这八大类中能同时满足承运物为易脏易损坏的纸箱并且需要运输的纸箱尺寸跨度较大,另外能实现双向运输的只有五大类22种。最后,将通过初筛的五类方案带入调研得到的场地实际情况进行验证。发现现有的方案并不能同时满足一些特殊的使用场地与使用要求,即设备可占用的水平投影方向上的长度与宽度狭小但却要实现大提升高度的运输,并且保证强运输稳定性与高生产效率。但查阅文献之后发现此类输送线上的提升机在国内外输送线设计与生产企业从未进行过产品的开发设计工作。所以,通过对现有方案的可行性进行分析,并使用约束理论根据场地调研得到的实际情况相结合,通过CRT框图与CRD框图分别对系统问题进行关联描述。进而寻找到造成提升机设计难点的本质问题与核心问题,从而确定导致问题产生的矛盾冲突为,对空间的占用既要扩大又要尽可能的减小。随后依托TRIZ理论中的分离原理为指导,设计了三种全新的输送线提升机方案。使用模糊综合评价法从三种输送线提升机的设计方案中评选出了最优方案。并完成了最优方案的零件细化、三维建模与装配。因为文章研究的属于工程实际问题,所以最终将细化之后的设备从空间布局与节拍效率的角度分别验证了全新集成设计的输送线提升机的可行性。为以后的研究人员再遇到此类场地情况提供了多种可以用来参考的思路与方案。
[Abstract]:Access to information can be found, the existing domestic and foreign traditional lifting equipment types of subdivision roughly more than 300. But most of the 300 lifting equipment are bulk hoists, among which only eight categories, less than 50 kinds of packaging can be transported. Through careful study, it can be found that in these eight kinds of cartons, the cartons which are easily dirty and easily damaged and need to be transported have a large size span, and only 22 kinds of cartons which can realize two-way transportation can be carried out in five major categories at the same time. Finally, five kinds of schemes are brought into the site to verify the actual situation. It is found that the existing scheme can not meet some special requirements for the use of the equipment, that is, the length and width of the horizontal projection direction occupied by the equipment are narrow, but the transportation with a large elevation should be realized. And ensure strong transport stability and high production efficiency. But after consulting the literature, it is found that the hoist on the conveyer line has never been developed and designed in domestic and foreign transportation line design and production enterprises. Therefore, by analyzing the feasibility of the existing scheme and combining the constraint theory according to the actual situation obtained from site investigation, the system problems are described by CRT block diagram and CRD block diagram respectively. Then find out the essential problem and the core problem that cause the difficulty in the design of the hoist, and then determine the contradiction and conflict that lead to the problem: the occupation of the space should be expanded and reduced as much as possible. Then, based on the separation principle of TRIZ theory, three new conveying line hoist schemes are designed. The fuzzy comprehensive evaluation method is used to select the optimal scheme from the design of three kinds of conveyer hoist. The parts refinement, three-dimensional modeling and assembly of the optimal scheme are completed. Because the research in this paper belongs to the practical engineering problem, the feasibility of the new integrated design conveying line hoist is verified from the angle of space layout and rhythm efficiency. It provides a variety of ideas and schemes for future researchers to meet such site situation.
