The field of packaging the product into circulation the necessary conditions, the primary means of packaging is the use of packaging machinery. With the development and advances in technology, packaging machinery in the circulation playing an increasing role. More than the traditional use of mechanical packaging machinery controls, such as the distribution cam shaft, and later appeared in electronic control, photoelectric control, pneumatic control, forms of control.
However, with increasing productivity, packing parameter random variable, these control systems have become increasingly difficult to meet the new situation. At this time, a new technology – electronic technology came into being, it completely changed the face of packaging machinery, to make it a new attitude in the world.
Characteristics of Mechatronics
In the current era of science and technology, new technologies, new processes, new materials, new equipment, there is no longer simply the development of a particular discipline, but the door-related disciplines, a variety of mutual penetration of advanced technology and complementary results. Mechatronics is such a new technology, it is in information theory, cybernetics and systems built on the basis of the integrated technology. The essence is from the system point of view, the use of process control theory, the mechanical, electronic and information technology for the detection of organic combination, to achieve overall optimization. Specifically, it is the computer technology into packaging machinery.
Mechatronics fundamentally changed the face of packaging machinery. In this packaging machinery, computers as its brain, replacing the conventional control system. Mechanical structure and its main trunk, a variety of instruments, meters, sensors, their senses, they feel the changes in a variety of packaging parameters, and feedback to the brain (computer), the various implementation agencies is its sibling, to complete the packaging operations necessary action.
A complete mechatronic system, generally include computer, sensors, power of the original, the transmission system, the executing agency and some other. It rejects the conventional packaging machinery in some of the complicated and unreasonable, while the machinery, computers, microelectronics, sensors and other multi-disciplinary integration of advanced technology, to the packaging machinery design, manufacturing and control have brought profound change, fundamentally changed the face of packaging machinery.
The role of packaging machinery
A new technology, once turned into productive, often play a huge role. Such as optical positioning error is much smaller than mechanical positioning, the effect of microwave on dry much better than electric heating and drying, etc., electromechanical integration technology for packaging machinery at the time not long, but the effect is obvious, the role is great .
So greatly simplified mechanical structure
Control system is the machine issuing the order organ, the traditional packaging machinery control system to use more relays, contactor control circuit, its complexity increases with the implementing agencies, as well as the increase in adjusted positions increased, making the machine more and more complex to manufacture, adjust, use and maintenance of all the inconvenience. The mechanical and electrical integration, computer available, sensing technology, new transmission technology to replace bulky electrical control cabinet and drive unit, so that the sharp decline in the number of components, greatly simplifying the structure, size also shrinks.
Product Quality
There are a huge computer storage system, it will affect the packaging machine can advance the work of the various parameters and the relevant data into the computer, it can automatically track the production process. When a parameter or several parameters change, this change in the instantaneous feedback to the computer, computer to identify parameters of these changes, estimate and consequential amendments in time to make packaging machine at any time to keep the best working condition. The conventional packaging machine in the process parameters change, the adjustment more empirically, which is difficult to find the best parameter; if several process parameters also change, even at a loss.
If the most common plastic bag sealing machine, the sealing quality and packing material, heat sealing temperature and speed and so on. Such as material (material, thickness) change, then the temperature and speed have to change, but change the number of Quenan grasp. Such as the use of computer control, various packaging materials to seal the best parameters of temperature and speed of computer memory, input matching, adding the necessary sensors to form the automatic tracking system, so regardless of which process parameters change, can guarantee the best sealing quality.
The more parameters to adjust some more, the greater the superiority of mechanical and electrical integration, which is the normal control mode can not be compared. Features increased reliability improved mechanical and electrical integration in addition to maintaining the original packaging machine function, can give many other features. Flexible packaging machine, such as liquid beverage, it is pneumatic, electrical and mechanical works with, it can be a system of boxes, sterilization, filling, sealing and other functions, if the introduction of the microcomputer control system, is also stored, such as production rate, product number of fault phenomena and fault reasons, the data, while the data can be treated accordingly based on the actual situation and the results printed out or displayed on the screen, greatly facilitate the operation. Mechatronic packaging machines will also be given to automatic monitoring, motion detection, alarm and other features, also has a safety chain control, overload protection and control functions, so that greatly improved the reliability of packaging machines.
