新型自动配料装车控制系统设计

新型自动配料装车系统设计

摘要

自动配料系统是一个针对各种不同类型的物料（固体或液体）进行输送、配比、加热、混合以及成品包装等全生产过程的自动化生产线。广泛应用于化工、冶金、建材、食品、饲料加工等行业。

本文主要围绕饲料厂配料工艺流程进行研究，包括配料系统的组成、配料流程、装车系统的组成、电子称的基本原理等等，应用PLC（可编程序控制器）技术，设计了自动配料装车系统,提出了可移动式料斗称双速进料式零位法称量的控制方案。使用siemens公司的可编程序控制器S7-200可以设计满足控制要求的自动配料装车控制系统。并且通过S7-200模拟仿真软件验证了系统的有效性。本设计的预期目标是改变以往配料系统的传统配料方式，提高运行人员工作效率，提高配料系统的配料精度，提高工业系统管理水平和生产效率，解决工业的配料装车问题，从而实现对资源的优化配置，提高工业效率和经济效益。

本文针对自动配料装车过程以及配料精度进行重点研究，得出可移动式料斗称双速进料式零位法称量的控制方案可以满足饲料厂的配料需求。

New type of automatic batching loading system

design

Abstract

Automatic batching system is one for all sorts of different types of materials (solid or liquid) for conveying and proportion, heating, mixing and finished product packaging of whole production process automation production line. Widely used in chemical industry, metallurgy, building materials, food industry, feed processing, etc.

This article mainly revolves the feed mills batching process is studied, including the composition of batching system, batching process, the loading system composition, the basic principle of electronic scale, etc., application of PLC (programmable Logic controller) technology, automatic batching loading system is designed and proposed mobile hopper said two-speed feeding type zero method weighing control scheme. Use of Siemens company's S7-200 programmable controller can be designed to meet the control requirements of automatic batching loading control system. And by S7-200 simulation software to verify the effectiveness of the system. Anticipated target of this design is to change the previous way of traditional ingredients system, enhances the working efficiency of the operation personnel, improving the batching accuracy of batching system, improve management level and production efficiency of industrial system, solve the problem of industrial ingredients loading, so as to realize the optimization of resource configuration, improve the industrial efficiency and economic benefits.

Dosing and loading process and precision, the author of this paper to focus on research, concluded that portable two-speed feeding hopper said type zero method weighing control scheme can meet the demand of feed mills in the ingredients.
