【摘要】：包装技术是现代文明的重要标志,而包装机械是实现现代文明的物质保证。随着企业用工成本的飙升及产业结构调整的深入,“机器换人”成为纺织企业的必然选择。因此,实现筒子纱的自动包装是大势所趋,是纺纱厂亟需解决的问题。目前,筒子纱包装多为人工包装,筒纱包装作为纺纱企业生产环节的最后一个步骤,存在人工成本高、包装强度大、包装效率低下等问题,是个单调重复而又繁重的工作。因此,论文提出了一种纺纱厂生产线末端自动化包装解决方案,设计了全自动筒子纱包装生产线,代替了传统的人工包装。本方案共包含三个部分,即物流系统、包装系统、控制及软件系统,实现了筒子纱从络纱机到码垛整个过程物流及包装的全自动化,实现了现场监控、生产数据管理等功能。论文设计的全自动筒子纱包装生产线综合运用了机电仪一体化技术、在线检测与控制技术、上位机监控技术、气动技术、通讯网络技术等原理与理论,生产线采用模块化设计理念,其中输送模块、预称重模块、配重模块、自动检测及调整大小头模块、单纱包装模块、自动排纱模块、整袋包装模块、喷码模块等均可独立工作,可根据不同需求,实现生产线不同功能的组合,实现了各模块的集成,保证了整条生产线的稳定、高速、协调、智能化运行,可做到无人值守。论文创新性地提出了筒子纱热缩膜包装方案,不仅实现了包装的自动化,而且包装效率高。针对全自动筒子纱包装生产线设计过程中的几个关键环节进行了重点研究,研究内容如下：1、根据筒子纱包装的工艺要求,结合现场条件,对全自动筒子纱包装生产线做了整体的规划。2、按照“模块化”设计理念,研究并设计了筒子纱热缩膜包装的整体方案,由PLC实现对整条包装生产线的精准控制,触摸屏实现对生产线的监控和报表输出等。3、对配重、自动检测及调整大小头、自动排纱等模块的原理、实现方式及功能进行了研究与设计；根据系统功能,对在线称重机、单纱／整袋包装、喷码等模块进行了选型和集成。4、研究并设计了整条包装生产线的硬件及软件架构,根据本系统的控制要求,设计了各模块的控制流程及上位机组态界面；对本系统的通讯网络进行了设计,并研究了配重模块数据处理的方法及算法设计。5、对本生产线中主要模块的称重精度、运行效率等参数进行了测试并分析,经过长期性的测试,本课题所设计的包装生产线运行可靠稳定,满足设计要求。
[Abstract]:Packaging technology is an important symbol of modern civilization, and packaging machinery is the material guarantee to realize modern civilization. With the soaring of labor cost and the deepening of industrial structure adjustment, machine replacement has become an inevitable choice for textile enterprises. Therefore, it is the trend of the times to realize the automatic packing of bobbin yarn, which is an urgent problem to be solved in spinning mills. At present, package of bobbin yarn is mostly manual packing. As the last step of spinning enterprise, yarn packaging has many problems, such as high labor cost, high packing intensity and low packaging efficiency. It is a monotonous and repetitive work. Therefore, this paper presents a solution of automatic packaging at the end of spinning mill production line, and designs a fully automatic package packing line instead of traditional manual packing. This scheme consists of three parts: logistics system, packaging system, control system and software system. It realizes the automation of the whole process of package packing and logistics from winder to palletizing, and realizes the functions of field monitoring, production data management and so on. The design of the automatic package production line of drum yarn is based on the principle and theory of integration technology of machine and electricity, on-line detection and control technology, upper computer monitoring technology, pneumatic technology, communication network technology and so on. The production line adopts the modular design idea, in which the conveying module, the pre-weighing module, the counterweight module, the automatic detecting and adjusting size head module, the single yarn packing module, the automatic yarn arrangement module, the whole bag packing module, the spray code module and so on all work independently. It can combine different functions of the production line according to different requirements, realize the integration of each module, ensure the stability, high speed, coordination, intelligent operation of the whole production line, and can be unattended. The paper puts forward the package scheme of package yarn heat shrink film creatively, which not only realizes the automation of packaging, but also has high packaging efficiency. This paper focuses on several key links in the design process of fully automatic package yarn packaging production line. The research contents are as follows: 1. According to the technological requirements of package, combined with the field conditions, The whole plan of automatic package production line of package yarn is made. According to the "modularization" design concept, the whole plan of package yarn with heat shrinkage film is studied and designed, and the precise control of the whole packing line is realized by PLC. The touch screen realizes the monitoring and report output of the production line. It also studies and designs the principle, the realization mode and the function of the modules such as counterweight, automatic detection and adjustment of the size head, automatic yarn arrangement, etc. According to the system function, the on-line weighing machine is studied and designed. Single yarn / bag packaging, spray code and other modules are selected and integrated. The hardware and software architecture of the whole packaging production line is studied and designed. According to the control requirements of the system, the control flow of each module and the configuration interface of the upper computer are designed. The communication network of the system is designed, and the data processing method and algorithm design of the weight distribution module is studied. The weighing accuracy and running efficiency of the main modules in this production line are tested and analyzed. The packaging production line designed in this paper runs reliably and stably and meets the design requirements.
