【摘要】：气动技术是当今工业自动化领域中的重要分支,拥有众多显著的优点,因其清洁无污染,工作效率高,成本低廉,使得其在工业自动化中得到愈来愈广泛的应用,是实现各种生产控制、自动控制的重要手段之一。作为一种控制手段,目前在大多相关的领域内电-气控制正在取代全气动控制,但在某些需要防燃、防爆、防静电的特殊场合,不适合采用电-气控制,因此全气动控制仍然在很多场合使用。本文以日本SMC公司提出的基于梯形图的全气动系统快速设计方法为引线,在全面、系统的阐述基于梯形图的全气动系统快速设计方法的设计思想、设计步骤的基础之上,通过对采用基于梯形图的全气动系统快速设计方法设计的全气动控制回路进行分析和研究,提出了系统的总体改进方案,根据提出的方案,首先对采用的特殊气动控制元件——气动顺序控制器的结构、工作原理和主要的优点进行了详尽的介绍；随后结合气动顺序控制器,融入顺序控制的设计思想,对典型的全气动多缸行程程序控制回路进行了合理设计,提出了一套比SMC基于梯形图的全气动系统快速设计方法简洁、直观的全气动系统快速设计方法；最后采用该新型全气动系统快速设计方法完成了全气动装弹机械手控制回路的设计,同时通过工程实际例证了该新型全气动系统快速设计方法的优越性。
[Abstract]:Pneumatic technology is an important branch in the field of industrial automation nowadays, which has many remarkable advantages. Because of its clean and pollution-free, high efficiency and low cost, pneumatic technology has been more and more widely used in industrial automation. It is one of the important means to realize all kinds of production control and automatic control. As a means of control, electropneumatic control is being replaced by electropneumatic control in most related fields at present, but it is not suitable for electropneumatic control in some special situations which need anti-combustion, explosion-proof and anti-static. Therefore, full pneumatic control is still used in many situations. In this paper, based on the rapid design method of all pneumatic system based on trapezoidal diagram proposed by SMC Company of Japan, the design idea and design steps of the rapid design method of all pneumatic system based on trapezoid diagram are expounded in a comprehensive and systematic way. Based on the analysis and study of the whole pneumatic control loop designed by using the rapid design method of the whole pneumatic system based on trapezoid diagram, the overall improvement scheme of the system is put forward, according to the proposed scheme, Firstly, the structure, working principle and main advantages of the pneumatic sequential controller, which is a special pneumatic control element, are introduced in detail, and then combined with the pneumatic sequence controller, the design idea of sequential control is introduced. The typical program control loop of full pneumatic multi-cylinder stroke is reasonably designed, and a set of rapid design method of full pneumatic system based on trapezoidal diagram based on SMC is put forward, which is simpler and more intuitionistic than the fast design method of full pneumatic system based on trapezoidal diagram. In the end, the control loop of the full pneumatic loading manipulator is designed by using the method of rapid design of the new type of full pneumatic system, and the superiority of the method is illustrated by the engineering practice.
