PLC is still a long time in the future will be the main rubber machinery controller

At present, China has become the world's largest rubber consuming country in 2005, consuming a total of 4,000,000 tons of natural rubber and synthetic rubber. The main rubber machinery, including chain-opened, mixer, calendar, and curing machine. By the rapid development of the automotive industry, China's rubber machinery industry has developed rapidly in the last 3 years of production value growth rate of 30% in 2005, output value of more than 6,000,000,000 yuan.

The use of rubber machinery automation products are the main control system, drive control, motion control, HMI and these types of sensors.

The use of rubber machinery is the main controller of the PLC, some of the equipment based on product-specific embedded controller, a simple stand-alone device used to control the relay. Rubber production in the process of rubber mixing, extrusion, the pressure of the three extension of the control process is relatively simple, just the general monitoring temperature, pressure, drive one or more aspects of the parameters of simulation in general have a small amount of IO will be able to meet the PLC Request. The curing machine and control complex, the need for location, temperature, pressure, velocity, and other parameters for precise control, machine control in the key position and velocity, the coordination motion control products; curing control key points in time Precise control of temperature and pressure and the opening and closing of the position control mode.

In addition to the use of a large number of stand-alone PLC, from the equipment and related auxiliary machinery constitute the production line is also used to control a large number of products, equipment for the control of coordination between the operation of accessories such as the rubber mixing process to transfer raw materials measurement, mixer The main motor-assisted control system, all the equipment control system as a sub-station access control system, some users still using the fieldbus technology.

2005 Chinese rubber machinery for the PLC market 050,000,000 yuan. Simple auxiliary machinery is commonly used by relay logic control. China Industrial Network that the controller's rubber machinery for a long period of time will remain the main PLC. Siemens, Omron, Rockwell, Mitsubishi, Rexroth rubber machinery is often used by the PLC brand, the brand name for rubber machinery related to the provision of equipment solutions are mostly based on field bus technology. The domestic rubber machinery manufacturers, service performance and their choice of the main controller, of course, the price of their value.
