Development of carton packaging machinery

Development of carton packaging machinery

The era of automation in the packaging industry began about 20 years ago, when all mechanical equipment was equipped with a programmable logic controller (PLC) for controlling the mechanical power shaft of logic functions and drives. However, the flexibility of this generation of automation equipment is not satisfactory. The life cycle of consumer products, especially food, is shortened, and the products tend to be diversified, which arouses the great demand for equipment flexibility. In the later developed generation automation equipment, more and more functions are transferred from mechanical power shaft to electronic drive system, and the logic function is still controlled by PLC system. The logic function originally executed by PLC is losing its importance, and now the electronic motion function is dominant. With the improvement of the flexibility of the equipment, the number of servo motors is also increasing. This means that physical and logical interfaces are no longer needed due to different programming languages and systems. Since the mid-1990s, some companies have driven the trend of integrated motion control and logic control solutions in the field of carton packaging machinery.
