PLC和触摸屏的板材输送单元控制系统设计+CAD图纸

摘要运输带广泛用于建材、化工、煤炭、电力、冶金等部门,适用于常温下输送非腐蚀性的无尖刺的块状、粒状、粉末的多种物料、如煤炭、焦炭、砂石、水泥等散物(料)或成件物品,输送堆积密度为6.5~2.5t/m3的各种块状、粒状、粉状等松散状物料,也可用于成体物品输送。49106

本设计中,利用PLC和触摸屏,设计一个板材输送单元的控制系统。在控制系统中,每个运输带既可以手动控制,又可以自动控制。手动控制时,既可以控制一条运输带,又可以控制多条运输带。控制多条运输带时,各运输带既可以以相同的速度运行,又可以以不同的速度运行。自动控制时,各运输带以相同的速度运行,自动控制启动后,一号运输带立即启动,为了防止运输带上物料的堆积,2号,3号,4号运输带,每隔5秒顺序启动。

本系统中的操作动作都在触摸屏上完成,在登陆系统后,可进行手动控制和自动控制,急停,以及报警的确认等工作。

Abstract

Transportation tapes are widely used in building material, chemical, coal, electric power, metallurgy and other departments,massive, granular , powder of a variety of materials , such as coal, coke, sand and gravel , cement and other bulk material ( material ) , or items applicable to conveying non- corrosive spikes at room temperature,transport packing density of 6.5~2.5t/m3 various massive, granular, powder and other bulk materials,can also be used for adult goods transportation.

In this design , the use of PLC and touch screen control system design of a sheet conveying unit . In the control system , the conveyor belt can manually control can be automatically controlled .Manual control , not only can control a conveyor belt , they can control the conveyor belt .Control the conveyor belt when the conveyor belt can either run the same speed , they can run at different speeds .Automatic control , the transport belt running at the same speed , One conveyor belt to start immediately after the start of the automatic control , in order to prevent the accumulation of the conveyor belt material on the 2nd , the 3rd , the 4th conveyor belt , every order of 5 seconds to start.

The action of the operating system on the touch screen in the landing system , manual control and automatic control , emergency stop , and alarm acknowledgment .

Keywords:PLC ,Touch screen ,conveyor belt
