【摘要】：目前,纺纱厂的筒子纱包装环节大多为人工包装。在工作过程中,操作员需要不断的重复同一工序,工作时间长而且呆板单一,操作员很容易感到疲劳,并且包装效率低、包装质量差。有的纺纱厂使用半自动包装设备用于代替部分包装工序,但仍需要大量人工参与。同时现在国内外市场上进行纱线交易时一般要求整包筒子纱的重量控制在较小误差范围内,但目前市场上的筒子纱包装系统普遍缺乏较准确的控制整包筒子纱重量的方法。因此,研究设计一种具有自动配重功能的筒子纱包装系统非常必要,以实现筒子纱从络筒完成后通过自动上纱装置进行上纱,对单个筒子纱进行称重及对筒子纱进行组合配重以控制整包筒子纱的重量,为纺纱车间实现自动化、智能化提供技术支持。本文首先分析了基于自动配重的筒子纱包装系统的整体设计方案,详细阐述了具有自动配重功能的筒子纱包装系统的自动上纱、单纱称重、筒子纱大小头检测及选择性翻转等关键机构的结构组成及工作原理,重点分析和设计了筒子纱自动配重装置的配重原理、配重方法及配重过程,并且对整个系统的相关软、硬件系统进行了设计,本文主要研究工作如下:1.根据筒子纱的包装工艺要求,结合人工包装的工作流程,确定了具有自动配重功能的筒子纱包装系统的实现方法及整体设计方案,并对整个系统的典型机构如自动上纱、基于光电与定时器的大小头状态检测、筒子纱选择性翻转等机构的功能实现、工作原理及机械结构进行研究与设计。2.对筒子纱的配重模块进行了研究设计,提出了一种筒子纱配重方法,并对配重模块的机械结构、工作原理及配重过程进行了分析与设计。采用气动系统作为整个包装系统的主要驱动执行机构,根据包装流程设计了气动系统的整体结构。3.对筒子纱自动包装控制系统的硬件部分进行了设计。根据控制需求研究与设计整个包装系统的硬件系统方案,采用西门子S7-300系列PLC作为主控制器,并对整个控制系统的电机、变频器及触摸屏等硬件进行了分析及选型。另外,对整个控制系统的通信网络进行了分析及设计;对控制系统的软件部分进行了设计开发,分析和设计了部分功能模块的软件程序流程,并对自动配重模块的软件编程进行了详细介绍,同时采用Wincc flexible软件进行触摸屏中显示界面的编辑设计,实现了人机交互功能。4.在完成本系统分析设计基础上,对本系统的典型机构的运动过程进行仿真分析,同时在课题组合作的企业对部分研究结果进行试验性测试。最后,对本文的研究工作进行了总结,指出了系统中存在的缺点和不足,并提出了系统后续的改进规划。
[Abstract]:At present, spinning mill bobbin packing links are mostly manual packaging. In the process of operation, the operator needs to repeat the same process continuously, the working time is long and rigid, the operator is easy to feel tired, and the packing efficiency is low, the packing quality is poor. Some spinning mills use semi-automatic packaging equipment instead of part of the packing process, but still require a large number of manual participation. At the same time, when dealing in domestic and foreign market, it is generally required that the weight of whole package bobbin should be controlled within a small error range. However, at present, there is a lack of more accurate methods to control the weight of whole package yarn in the packaging system of bobbin in the market. Therefore, it is very necessary to study and design a bobbin packing system with automatic weighing function, so that the bobbin can be spun through the automatic winding device after the winding is completed, and it is very necessary to design the bobbin packing system with the function of automatic weighing. The weighing of a single bobbin and the combined weighing of the bobbin are used to control the weight of the whole package, which provides technical support for the automation and intelligentization of the spinning workshop. In this paper, the whole design scheme of the bobbin packing system based on automatic weighing is analyzed firstly, and the automatic winding, single yarn weighing of the bobbin packing system with automatic weighing function is described in detail. The structure composition and working principle of the key mechanism, such as the detection of the size and size of the bobbin and the selective turnover, are analyzed and designed. The principle, method and process of the automatic weighing device of the bobbin are analyzed and designed, and the relative soft of the whole system is analyzed and designed. The hardware system is designed. The main research work of this paper is as follows: 1. According to the packing technology requirement of the bobbin and the work flow of manual packing, the realization method and the whole design scheme of the bobbin packing system with automatic weighing function are determined, and the typical mechanism of the whole system, such as automatic winding, is determined. The function realization, working principle and mechanical structure of the mechanism based on photoelectric and timer detection of the size and size of the head, the selective flip of the bobbin yarn, and so on are studied and designed. 2. This paper studies and designs the weighing module of bobbin yarn, puts forward a method of weighing of bobbin yarn, and analyzes and designs the mechanical structure, working principle and process of weighing module of bobbin.
