摘 要

我国木材业存在着较大的市场和良好的发展前景。随着我国木材行业的发展，废弃木材的处理和再利用显得尤其重要。人工捆扎废弃木材的方式存在的弊端促使可调式树枝捆扎机的研究和发展。本论文重点研究可调式树枝捆扎机的监控系统，意在设计出一套能够取代人工方式的，实现由散落废弃树枝到打包整理完成的自动捆扎加工过程。此次毕业设计采用可编程控制器PLC与工控组态软件MCGS的结合，设计出自动捆扎与校正的模拟界面，显示出可调式树枝捆扎机监控系统的全部可实现效果。与此同时，设计出集自动和手动于一体的监控系统，实现废弃树枝的自动传输、快速压缩、高效捆扎及输送的自动加工过程，使该系统适用于户外恶劣的生产环境。本文解决了木材行业废弃树枝再利用率低下以及人工处理效率低等一系列问题，成功将工控组态软件和可编程控制器利用到了工业生产现场。

Design of Monitor and Control System for Adjustable Tree Binding Machine

ABSTRACT

China's timber industry there is a large market and good prospects for development. With the development of China's timber industry, the disposal and reuse of waste wood is particularly important. The shortcomings of the way of artificial bundling of waste wood prompted the research and development of adjustable tree bundles. This paper focuses on the monitoring system of adjustable tree bundling machine, which aims to design a set of automatic bundling process which can replace the artificial way and realize the completion of the discarded branches from the scattered branches. The graduation design uses programmable logic controller PLC and industrial control configuration software MCGS combination, designed the automatic binding and correction of the simulation interface, showing the adjustable tree bundling machine monitoring system can achieve all the results. At the same time, the design of a set of automatic and manual in one of the monitoring system to achieve the automatic transmission of discarded branches, fast compression, efficient bundling and transportation of the automatic processing process, the system is suitable for outdoor harsh production environment. This paper solves a series of problems such as low utilization rate of waste tree branches and low manual processing efficiency in wood industry, and successfully utilizes industrial control configuration software and programmable controller to industrial production site.
