【摘要】：包装机械是包装工业的重要基础,包装机械的水平是包装工业发展关键,并且其在轻工机械行业中占有重要地位。筒子纱自动包装成套设备作为包装机械的一种,用于完成筒子纱自动包装的所有过程。目前,筒子纱包装大多由人工完成或者由机器代替部分工序完成。包装时,人需要长时间机械地重复单调的工作,非常容易使人疲劳,并且人工包装的效率较低,会占用大量的人力资源。现在已经出现筒子纱自动包装机,但依然不能完全实现包装过程的自动化。设计一种可以实现筒子纱自动包装的自动化设备,亟需进一步研究,也符合我国纺织行业对包装设备的迫切需求。筒子纱自动包装成套设备是自动化、智能化的用于纺织行业的包装设备,是集检测技术、机械设计、气动技术、电力拖动和实时控制于一体的自动包装流水线。整套设备由多个机构或设备组成,每个机构或设备负责一道包装工序,各部分分工协作,共同完成筒子纱的自动包装过程。设备的安全性、可靠性和实用性是保证系统有效完成任务的关键。本文分析了筒子纱的包装过程,研究并设计了筒子纱自动包装成套设备,针对自动包装过程中的几个关键环节和技术进行了如下几个方面的研究：研究筒子纱的包装工艺和要求,确定了利用自动化设备包装筒子纱的流程,运用模块化设计方法完成整个系统的软硬件方案。由PLC统一控制整个包装过程,通过触摸屏和上位机组态实现整套设备的运行监控和参数设置。运用机械设计技术和传感器检测技术实现各个模块的设计,从功能原理、装置结构和成本等方面对比每个模块的实现方式,选择最合理的设计方案。采用气动方式驱动执行机构,根据功能要求选择封塑设备、称重设备和喷码机。研究气动系统,对气动系统进行理论分析与计算,设计气动系统的整体结构；根据功能要求选择气动元件,完成整个气动系统的设计方案。研究工业现场中常用的控制方式,选择合适的控制器并设计控制单元的硬件系统,研究并设计了筒子纱输送线及其速度规划与控制；设计系统的通信网络及硬件抗干扰措施,实现PLC与喷码机、变频器和称重终端的数据交换。在硬件参数满足控制要求的基础上,设计了控制系统各个子功能模块的流程和软件；设计了操作面板和上位机的功能与组态画面,实现筒子纱自动的包装过程监控、数据归档和报表输出。最后分析了筒子纱自动包装成套设备的各项性能,分析了系统的可靠性和实用性,分析了系统的创新性与先进性,总结了本课题设计的自动包装设备在速度、效率和功能等方面的优势。
[Abstract]:Packaging machinery is an important foundation of packaging industry, the level of packaging machinery is the key to the development of packaging industry, and it plays an important role in light industry machinery industry. Package yarn automatic packaging equipment as a packaging machinery, used to complete all the package yarn automatic packaging process. At present, the package of package yarn by manual or machine instead of part of the process completed. When packaging, people need to repeat the monotonous work for a long time mechanically. It is very easy to make people tired, and the efficiency of artificial packaging is low, which will take up a lot of human resources. Now automatic packaging machine has appeared, but still can not fully automate the packaging process. It is necessary to design an automatic equipment for automatic packaging of package yarn, which needs further research and meets the urgent need of packaging equipment in China's textile industry. Automatic package equipment is an automatic, intelligent packaging equipment for textile industry. It is an automatic packaging assembly line which integrates testing technology, mechanical design, pneumatic technology, electric drive and real-time control. The whole set of equipment consists of a number of institutions or equipment, each organization or equipment responsible for a packaging process, each part of the division of labor cooperation, together to complete the automatic packaging process of package yarn. The safety, reliability and practicability of the equipment are the key to ensure the effective completion of the system. In this paper, the packing process of package yarn is analyzed, and the complete set of equipment for automatic packing of bobbin yarn is studied and designed. Several key links and techniques in the process of automatic packaging are studied in the following aspects: the packaging process and requirements of package yarn are studied, and the process of packaging package yarn with automatic equipment is determined. The software and hardware scheme of the whole system is completed by modularization design method. The whole packaging process is uniformly controlled by PLC, and the operation monitoring and parameter setting of the whole equipment are realized through the configuration of touch screen and upper computer. The mechanical design technology and sensor detection technology are used to realize the design of each module. The most reasonable design scheme is selected from the aspects of function principle, device structure and cost. Pneumatic drive actuator, according to the functional requirements of the selection of plastic sealing equipment, weighing equipment and inkjet machine. The whole structure of pneumatic system is designed by theoretical analysis and calculation of pneumatic system, and the pneumatic components are selected according to the functional requirements to complete the design scheme of the whole pneumatic system. The commonly used control methods in the industrial field are studied, the appropriate controller is selected and the hardware system of the control unit is designed, and the silo yarn conveying line and its speed planning and control are studied and designed. The communication network and hardware anti-jamming measures of the system are designed to realize the data exchange between PLC and inkjet printer, inverter and weighing terminal. On the basis of the hardware parameters meeting the control requirements, the flow chart and software of each sub-function module of the control system are designed. The function and configuration picture of operation panel and upper computer are designed to realize automatic packing process monitoring data archiving and report output. Finally, the performance of package equipment for automatic packaging of package yarn is analyzed, the reliability and practicability of the system are analyzed, the innovation and advanced nature of the system are analyzed, and the speed of the automatic packaging equipment designed by this subject is summarized. The advantages of efficiency and function.
