筒子纱自动包装系统的设计与研究
|
摘要
包装机械是发展包装工业的关键,正向着智能化、自动化、高效率、多功能、低消耗方向发展。筒子纱自动包装机作为包装机械的一种,用于实现筒子纱的自动包装。
目前,筒子纱主要依靠人工包装,但随着筒子纱生产自动化程度的提高,人工包装已经无法满足生产要求,国外已经研究出筒子纱自动包装机,但并不能完全实现自动化,在几个环节都需要人工的参与,且成本较高。因此开发具有自主知识产权的筒子纱自动包装机符合我国纺织行业的迫切要求。
筒子纱自动包装系统作为一个高速度、智能化、全自动的纺织行业包装设备,是集在线检测、精密机械、实时控制于一体的大型包装生产线,要求各部分协调配合,同时保证整个系统的可靠性与稳定性。本文通过对筒子纱包装过程的分析,综合运用了自动控制、机械自动化、计算机技术、仪器仪表、通信网络等众多学科知识,研究与设计了筒子纱自动包装系统。
针对筒子纱自动包装系统中的几个关键技术进行了以下几个方面的研究：
1、根据筒子纱包装的工艺要求,确定了筒子纱自动包装的流程,并提出了“统一控制,分模块设计”的思路,由PLC对整个包装过程进行控制,由触摸屏对现场进行监控,通过上位WinCC组态实现在控制室对整个包装过程的监控和报表输出。
2、设计了系统的整体方案,从原理上对比了各模块实现的方式,找出最简单可靠的设计方法,分别设计了各模块的机械结构,并采用气动系统驱动执行机构,完成包装过程的各个工艺流程,对现有设备做了选型。
3、研究了气动系统的总体结构,从原理上分析了气动元件和配管的配置方法,对本系统所需要的气动元件进行了选型,设计了完善的气动系统。
4、设计了系统控制单元的硬件结构,研究了输送线的调速技术与原理,设计了本系统的通讯网络,根据本系统设计的特点,研究了本系统中的硬件抗干扰措施。根据本系统的硬件结构和系统的控制要求,设计了本系统的控制软件以及各模块的控制流程；根据对监控系统的要求,设计了上位机组态界面；并研究了PLC与系统主要模块的通信方式。
5、研究了本系统各段输送线的速度配合策略,设计了自适应模糊PID控制器,并通过系统仿真,分析了控制效果。对本系统的安全性、可靠性和稳定性做了分析,将本系统与现有设备做了比较,并分析了本系统的技术创新性。

Currently, cheese packaging mostly relies on artificial packaging, but with the cheese production increased automation, artificial packaging has been unable to meet the production requirements. Automatic cheese packaging machine has been developed abroad, but it is not fully automated. In several aspects, artificial participation is required, and the cost is higher. Therefore, the development of cheese automatic packaging machine with independent intellectual property rights meets the urgent requirements of the textile industry in China.
Cheese automatic packaging system as a high-speed, intelligent, automatic packaging equipment in textile industry, is a large-scale packaging production line with the on-line detection, precision machinery, real-time control. It requires the coordination and cooperation of every part, while ensures the reliability and stability of the entire system. This paper researches and designs cheese automatic packaging system by analyzing the cheese packaging process, the integrated use of automatic control, mechanical automation, computer technology, instrumentation, communication network and many other disciplines of knowledge,.
This paper studies on the following aspects in several key technologies of cheese automatic packaging system:
1、According to the requirements of cheese packaging craft, the process of the automatic packaging and the idea of "unified control, sub-module design" are decided. The PLC controls entire packaging process, the touch screen monitors the site and the upper WinCC monitors the entire packaging process in the control and outputs report.
2、This paper designs the overall scheme of the system, compares the principle of each module, to find the most simple and reliable design methods, designs the mechanical structure of each module, use pneumatic system to drive the actuator to complete the packaging process, and select existing equipments.
3、This paper studies the overall structure of the pneumatic system, analysis pneumatic components and the method of piping configuration from the principle of the system, selects pneumatic components, and designs a perfect pneumatic system.
4、This paper designs the hardware structure of the system control unit, studies the conveyor line speed control technology and principle, designs the communication network of the system, and studies the system hardware anti-jamming measures, based on the characteristics of the system design.
