【Abstract】 With the rapid economic development, the industrial brushes have being short supply in China. The canroy machine is used to produce the industrial brushes. The canroy machine has slowly developed in China. Because of production processes immature of the canroy machine, the quality of the industrial brushes is not satisfactory. So the studies of this technology are a focus in the industry.The product line of the canroy machine is composed of feeding material ahead and jointing in the back. The discrete control system can be accomplished by both SCM(single chip micyoco) and PLC (programmable logic controller). This paper analyzes the jointing in the back, which is a pivotal step, with discrete control. And the following works have been mainly done in the process of designing and researching.1. With analyzing the technology of SCM, the control system has been designed by 51 SCM according to the control requirements of the jointing. The switch is one of the input devices. After analyzing its characteristic, we have worked out the input circuit of limit switch, photoelectric switch and magnetic switch. Meanwhile, the relay is one of the output devices. After analyzing its characteristic, we have worked out the corresponding output circuit. The canroy machine has been designed by 8051 SCM, and this paper analyzes the advantages and disadvantages of the design scheme.2. We have researched and analyzed the PLC, the DC input, AC input, transistor output, relay output of PLC and the corresponding internal circuit. According to the control requirements, every function in the control system and system security have been accomplished by Mitsubishi FX1S-30MR PLC, at the same time, the solenoid valve gas connection system and the power distribution cabinet have been designed. The COOLMAY configuration screen has been worked out to real-time monitoring and human-computer interaction. Large of experiments on the new products in the laboratory have been done, and the new products have been put through a preliminary test in the factory. All the automatic control requirements of the canroy machine have been accomplished by FX1S-30MR PLC. The stable and reliable control system has been used to produce brushes.
