Application Status of Controllers in Packaging Machinery Industry

The use of controllers in packaging machinery is quite different. Large-scale production lines use fieldbus technology. Control points are as many as thousands. Most of the single-machines use PLCs or dedicated controllers, and some low-end devices use relay control methods. More small devices do not use any electronic controllers. In general, only about 10% of domestic packaging machinery use advanced controllers.

IPC is best from the performance, has strong expansibility, abundant software resources make it can develop more application schemes, it is mainly used for the management and communication of the large-scale apparatus at present. The embedded controller has the characteristics of high communication speed, convenient communication, and low cost when used in batches. PLC's reliability is the best and it is easy to develop to meet the requirements of all current packaging machinery. The PLC system can be large or small and will remain the mainstream controller of packaging machinery within five years; relays, as the mainstream controllers in the past, will continue to continue in the low-end market. Although the market has declined, but in the next few years in the packaging machinery The industry will still have a certain market space. However, it will not be eliminated in the packaging industry within 3 years.
