【摘要】 随着我国经济水平的持续提升,劳动力成本不断攀升,企业面临日益严峻的用工压力。为应对这一挑战,纺织企业正逐步采用自动化设备替代人工,以提升车间自动化水平,实现生产工序的半自动化或全自动化,从而提高工作效率。在纺织生产中,筒纱的上落纱工序是整经前处理生产环节之一,其主要任务是将纱线从纺纱机或络筒机上取下并重新安装到筒子架上,以便进行后续的整经、织造等工序。这一工序的自动化水平直接影响整经的生产效率。而在上落纱工序中,筒纱外包装薄膜的去袋工作目前国内外基本还是都是人工进行。本课题基于广东某公司的实际需求,以提升织造效率和提高整经前处理工序自动化为目标提出了一种用于上落纱生产线的去除筒纱包装薄膜的装置,为提升此公司纺织生产的整经前处理阶段生产效率提供了新的解决方案。主要研究工作包括:1.需求分析与装置设计。根据项目需求,将筒纱外包装自动化去除装置划分为四个子模块:输送模块、翻转送料模块、去袋模块和夹取给料模块。通过结构设计和Solid Works建模实现四个模块的协同作业,完成筒纱的自动去袋操作。2.子模块中部件仿真分析。完成结构设计后,首先利用ADAMS软件对翻转送料模块进行动力学计算,通过其在翻转状态和推料状态下的运行状态给筒纱在运行过程中的稳定性提供了一个仿真理论支撑。其次,对去袋模块中的去袋滚筒进行了静力学仿真与模态分析。静力学分析结果显示,去袋滚筒的最大变形量为9.8e-3mm,最大等效应力为8.8MPa。模态分析结果表明,该结构在不会发生共振现象。3.去袋滚筒结构的优化设计。针对去袋滚筒在运行中因挤压产生的形变过大问题,结合其工作状态下对形变量的要求,采用响应面优化方法对去袋滚筒进行优化设计。优化后,滚筒中的挤压部分形变量减少了7%,最大等效应力降低了17.14%,使其满足较高负载下的应变要求。4.电气控制系统设计与验证。基于西门子S7-1200PLC,完成了整个装置的电气控制方案硬件选型、梯形图程序设计以及人机交互界面开发。通过仿真给控制程序的可行性和稳定性提供依据。更多还原

【Abstract】 With the continuous improvement of my country’s economic level,labor costs continue to rise,and enterprises are facing increasingly severe employment pressure.In response to this challenge,textile enterprises are gradually adopting industrial robots to replace manual labor to improve the level of workshop automation,realize semi-automation or full automation of production processes,and thus improve work efficiency.In textile production,the process of bobbin yarn doffing is one of the production links of warping pretreatment.Its main task is to remove the yarn from the spinning machine or winding machine and reinstall it on the creel for subsequent warping,weaving and other processes.The automation level of this process directly affects the production efficiency of warping.In the process of doffing,the bag removal of the outer packaging film of the bobbin yarn is still basically done manually at home and abroad.Based on the actual needs of a company in Guangdong,this project proposes a device for removing the bobbin yarn packaging film for the doffing production line with the goal of improving weaving efficiency and improving the automation of the warping pretreatment process,which provides a new solution for improving the production efficiency of the warping pretreatment stage of this company’s textile production.The main research work includes:1.Demand analysis and device design.According to the project requirements,the automatic device for removing the outer packaging of the bobbin yarn is divided into four sub-modules:conveying module,flip feeding module,bag removal module and clamping feeding module.Through structural design and Solid Works modeling,the collaborative operation of the four modules is realized to complete the automatic bag removal operation of the bobbin yarn.2.Simulation analysis of components in sub-modules.After completing the structural design,the ADAMS software is first used to perform dynamic calculations on the flip feeding system.Its operating state in the flipping state and the pushing state provides a simulation theoretical support for the stability of the bobbin yarn during operation.Secondly,the static simulation and modal analysis of the bag removal drum in the bag removal module are carried out.The force condition of the drum is simulated by ANSYS software to simulate and verify the rationality of its structural design.3.Optimization design of the bag removal drum structure.In view of the problem of excessive deformation of the bag removal drum due to extrusion during operation,combined with the requirements for deformation under its working state,the response surface optimization method is used to optimize the design of the bag removal drum.After optimization,the deformation of the extrusion part in the drum is reduced by 7%,and the maximum equivalent stress is reduced by17.14%,so that it meets the strain stress requirements under higher loads.4.Design and verification of electrical control system.Based on Siemens S7-1200PLC,the hardware selection,ladder diagram program design and human-computer interaction interface development of the electrical control solution of the whole system were completed.The feasibility and stability of the control program were verified through simulation.更多还原
