袜子自动包装机的设计与分析

Design and Analysis of Automatic Packaging Machine for Socks

目的为了解决袜子生产后期包装问题,设计一种袜子自动包装机。方法针对袜子包装工艺要求,采用模块化设计思想对包装机关键机构进行设计,以此来实现袜钩自动输送,纸卡存取及自动弯折,袜子空间转运与缝订等功能。设计过程采用SolidWorks及其Motion插件进行结构建模、虚拟装配和运动仿真,采用Matlab以及Ansys的Workbench模块建立关键零部件力学模型,并进行有限元分析,最后通过与人工包装对比来分析包装机的性能。结果包装机各装置设计合理。经分析,无袜钩包装时,6.9 s可输出一件包装成品;有袜钩包装时,7.6 s可输出一件包装成品,在同等时间内相当于2~3名熟练包装工的工作量。结论所设计的袜子自动包装机结构合理,且满足袜子包装功能要求,为袜子自动包装提供了一种可行的解决方案。

The work aims to design an automatic socks packaging machine to solve the problem of packaging in the later stage of socks production.According to the requirements of socks packaging technology,the key mechanism of the packaging machine was designed with modular design ideas to achieve functions such as automatic transportation of sock hooks,paper card access and automatic bending,sock space transfer and stitching.In the design process,Solidworks and its Motion plug-in were used for structural modeling,virtual assembly and motion simulation.Matlab and Ansys Workbench modules were used to establish key component mechanical models and perform finite element analysis.Finally,the performance of the packaging machine was analyzed by comparing with manual packaging.The design of each device of the packaging machine was reasonable.According to analysis,when there was no sock hook,the packaging machine can output a packaged product in 6.9 seconds.When there was sock hook,packaging machine can output a packaged product in 7.6 seconds,which was equivalent to the workload of 2 to 3 skilled workers in the same time.The design of automatic sock packaging machine has a reasonable structure and meets the functional requirements of sock packaging,which provides a feasible solution for automatic sock packaging.
