| 目的 设计一套自动筛选设备，实现残次品的自动筛选和剔除。方法 结合纤维定向分布概率密度函数思想及连续介质力学理论对缝合区域进行分析，建立缝线力学特性模型；为确保筛选机构的真空吸盘群与编织袋底口缝合区域表面形成的负压满足要求，建立真空系统的真空度、透气度、时间三者之间的数学模型。结果 推导出了缝线区力学特性参数、系统真空度、透气度、时间之间的关系，根据各参数之间的关系，采用三维制图软件Pro/E进行实体建模，并选取相关控制元器件完成了设备结构设计和控制系统搭建。结论 该自动编织袋残次品筛选系统能够将有缝合瑕疵的产品筛选并剔除，且能大幅度提高编织袋生产效率和降低生产成本。 |

| The work aims to design a set of automatic screening equipment to achieve the automatic screening and elimination of defective products. Combined with fiber orientation probability density functions and continuum mechanics theory, the mechanical properties of suture were established by analyzing the suture area. To ensure that the pressure formed on the surface of the bottom suture areas of the screening mechanism’s vacuum chuck group and woven bag met the requirements, the mathematical model for vacuum degree, air permeability and time was established. The relationship between mechanical characteristic parameters, system vacuum, air permeability and time was derived. According to the relationship between the parameters, a solid model was developed by three-dimensional drawing software Pro/E. Then relevant control components were selected to design the equipment structure and build the control system. The automatic screening system for defective woven bag can screen and eliminate the products with suture defects, and greatly improve the production efficiency and reduce the production cost of the woven bag. |
