文档介绍：基于PLC自动配料皮带运输机控制系统的设计
摘要
在现代化的工业生产中常常需要对物料进行加工、搬运,如果这些繁杂的工作由人工完成的话不但效率低,而且劳动强度大,不适合现代化的生产需要。本文主要对基于PLC自动配料皮带运输机控制系统进行了详细的研究,该系统有两大部分构成:自动配料装置及皮带运输机控制系统。该控制系统具有精度高、成本低、抗干扰能力强、故障率低、操作维护简单等特点,具有良好的应用价值,在建材、化工、食品机械、钢铁、冶金、煤矿等工业生产中广泛使用。
本次设计主要的内容:采用三菱FX2N系列PLC实现控制系统的设计,着重从带式运输机,液体混合装置系统两个方面深入研究,确定其控制要求,明确PLC的机型的选择,确定I/O地址的分配,设计I/O接线图、控制流程图及梯形图,深入理解PLC的编程方法,按照控制要求对自动配料皮带运输机系统进行编程。

PLC-BASED AUTOMATIC CONTROL SYSTEM FOR
BELT CONVEYOR DESIGN
ABSTRACT
In modern industrial production is often a need for materials for processing, handling, if plexity of the pleted by the manual, then not only inefficient, but also labor-intensive, not suitable for modern production. In this paper, PLC-based automatic control system for belt conveyor carried out a detailed study, which consisted of two major systems: Automatic batching plant and control system for belt conveyor. The control system has high accuracy, low cost, anti-interference ability, low failure rate, simple operation and maintenance, has a good application value, In building materials, chemical industry, food machinery, iron and steel, metallurgy, coal and other widely used in industrial production.
The main design elements: the use of Mitsubishi FX2N Series PLC control system design, focusing on transport belt, liquid mixing device-depth study of two aspects of the system to determine control requirements, the model explicitly the choice of PLC, determine the I / O address allocation, the design of I / O wiring diagram, control flow chart and the ladder, in-depth understanding of PLC programming method, in accordance with the control requirements of the transport belt automatic programming system.
