【正文】 l. In conveying unit control program, you can use the signals of the state of the ponent to drive the manipulator device, to travel. This under the action of gravity, the workpiece automatically move down the artifacts, ready for the next grab artifacts. If the current plate without artifacts, material plate will continue to test the expected position under program control. Until the two dishes no artifacts, material plate stop running. the pneumatic circuit design Pneumatic actuator, control loop is the unit of work consists of pneumatic manipulator and feeding wheel, finish loading and discharge. Manipulator in structure consists of two straight line of cylinder, a swinging cylinder and claw. Place status to: paw closed gas, shift cylinder, lifting cylinder, cylinder 0 176。. A working cycle: the paw closed gas claws open qi translation cylinder into claw gas cylinder closed translational cylinder to cylinder 180 176。, back translation cylinder into the gas lift cylinder fall claw open to shift cylinder annealing, lifting cylinder to cylinder 0 176。. Robots can do translation, lifting and swinging arm claw grasping motion, by magnetic proximity switch installed in each cylinder cylinder test limit position, and then by the PLC to realize position control. WuLiangWei fiveway double electric solenoid valve installed on the collector plate, control of mechanical arm translation, lifting and swinging control and feeding plate rotating movement. PLC control In feeding unit, magnetic switch, position detection plate cylinder material without artifacts photoelectric switch, transmission congestion detection sensor and control buttons, PLC, a total of 14 received signal input terminal. Electromagnetic valve to control the movement of the output, the fault signal and the signal, a total of 13 output terminals. The main unit can choose Siemens s7300 and the exchange of information between from the station. 2. The software design of the system Design method of PLC ladder diagram program has two kinds of empirical method and sequence control. Sequential control design method is the basic idea of the system of a working cycle is divided into several connected to a sequence of steps, with programming ponents (such as memory M) to represent, in any step in the state of each output unchanged. Make the system by the current step into the next step signal is called the transition conditions, it can be an external input signal, such as buttons, such as the limit switch on and off. Can also be a PLC, the signals produced by internal contact signals such as timers and counters. Using sequential control design method, first of all, based on the system of technological process, as shown in the order of the functional diagram, function drawing out the ladder diagram according to order to plete the program design.
