衣物自动包装机折叠机构设计与优化

Design and Optimization of Folding Mechanism of Automatic Clothing Packing Machine

针对目前衣物包装机中折叠衣物部分结构复杂,其控制系统灵敏度、协调能力低下等问题,课题组设计了一种新型衣物折叠机构。首先,基于单驱动多凸轮的传动方式提出了折叠机构的设计方案与工作原理;其次,利用解析法对机构中曲柄滑块以及凸轮轮廓的尺度参数进行分析与确定;最后,通过ADAMS软件对机构进行运动仿真,并对运动过程中的最小传动角进行优化。其优化结果表明:最小传动角相较于优化前增大62%,满足设计要求。对比传统衣物折叠机构,该机构实现了以单个原动件来完成衣物的折叠过程,具有控制效率高,传动性能好和成本低等优点。

In view of the complex structure of the folding part of the current clothing packaging machine,and the low sensitivity and coordination ability of the control system,a new type of clothing folding mechanism was designed.Firstly,based on the transmission mode of single drive and multiple cams,the design scheme and working principle of folding mechanism were proposed.Secondly,the scale parameters of the slider-crank and the camprofile in the mechanism were analyzed and determined by the analytical method.Finally,the motion simulation of the mechanism was carried out by ADAMS software,and the minimum transmission angle in the process of motion was optimized.The optimization results show that the minimum transmission angle increases by 62%compared with that before optimization and,which meets the design requirements.Compared with the traditional folding mechanism,this mechanism realizes the folding process of clothing by a single original moving part,which has the advantages of high control efficiency,good transmission performance and low economic cost.
