Packaging machinery characteristics and advantages of mechanical and electrical integration
Packaging of products into the circulation of the necessary conditions, while achieving the primary means of packaging the use of packaging machinery. With the development of advances in technology, packaging machinery in the circulation of playing a growing role. Packaging machinery to use more traditional mechanical control, 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 of random variable, these control systems have become increasingly difficult to meet the new situation. At this time, a new technology: mechanical and electrical integration technologies have emerged, it completely changed the face of packaging machinery to make it a new attitude appeared in the world.
1, mechanical and electrical integration of technology features:
1, in the present era of science and technology, various new technologies, new processes, new materials, new equipment, there is no longer simply a discipline of development, but the doors related disciplines, a variety of advanced technology interpenetrate and mutually reinforcing results. Mechatronics is a new technology such as it is in the information theory, cybernetics and systems theory built on the basis of comprehensive technology. The essence is from the system point of view, the use of process control theory, mechanical, electronics and information, testing and other relevant technologies and organically combined to achieve overall optimization. Specifically, it is the computer technology into packaging machinery.
2, electromechanical integration, fundamentally changed the face of the packaging machinery. In this packaging machinery, computer as its brain, replacing the conventional control system. Mechanical structure is its main body and torso, all kinds of instruments, meters, sensors, their senses, they experience all kinds of packaging parameters change and feedback to the brain (computer), the various enforcement agencies in its hand, foot and to complete the packaging operations necessary action.
3, a complete mechatronic systems, generally include computers, sensors, power sources, transmission systems, the executing agency and some other. It rejects the conventional packaging machinery in the red tape and unreasonable parts, mechanical, computer, microelectronics, sensors and other multi-disciplinary integration of advanced technology, to packaging machinery in the design, manufacturing and control have brought about profound change, fundamentally changed the face of packaging machinery.
2, mechanical and electrical integration of packaging machinery advantages:
A new technology, once turned into productive forces, and often will play a huge role. Such as optical positioning error is far smaller than the mechanical positioning, the effect of microwave drying is much better than electric heating and drying, etc., electromechanical integration technology for packaging machinery in the time not long, but the effect is obvious, the role is enormous. Mechanical and electrical integration of packaging machinery advantages:
1, so that the mechanical structure greatly simplified.
Control system is the machine issuing the order organ, the traditional packaging machinery control system for multi-use relay, contactor control circuit, its complexity increases as the implementing agency, as well as an increase in adjusted positions increased, making the machine more and more complex , to create, adapt, use and maintenance of both inconvenience. The mechanical and electrical integration, available computers, sensor technology, new transmission technology to replace bulky electrical control cabinet and drive unit, so that the sharp decline in the number of components, structure, greatly simplified, the volume also will be reduced.
2, the product quality.
There are a huge computer storage systems, people can pre-packaging machine will affect the work of the various parameters and relevant data into the computer, it can automatically track the production process. When a parameter or several parameters change, this change in an instant feedback to the computer, computer for these changes to identify parameters to determine in a timely manner and make the appropriate amendments to bring the packaging machine at any time to maintain the best working condition. The traditional packaging machine in the process parameters change, the adjustment of multiple rule of thumb, making it difficult to find the best parameters, if the number of process parameters also change, but also at a loss. As the most common plastic bag sealing machine, the sealing quality and packaging materials, heat-sealing temperature and running speed and other relevant. Such as material change (material, thickness), it also changes the temperature and speed, but change the number of Quenan grasp. Such as the use of microcomputer control, all kinds of packaging materials sealing temperature and the optimum parameters match the input speed computer memory, matched with the necessary sensors to form the automatic tracking system, so that, regardless of which process parameters to change, can ensure the most excellent sealing quality.
The more parameters to adjust some of the more mechanical and electrical integration, the greater the superiority of this is a general control method can not be compared.
3, functionality increased, increased reliability.
In addition to mechanical and electrical integration, can maintain the original packaging machine functions, but also gives many other features. Flexible packaging, such as liquid beverage machines, it is pneumatic, electrical and mechanical works with, may have a system of boxes, sterilization, filling, sealing and other functions, but when the introduction of computer control system, it may also store such as production rate, the number of products, failure phenomena, cause of the malfunction and other data, while data can be dealt with accordingly based on actual conditions and the results printed out or displayed on the screen, greatly facilitate the operation.
Mechatronic packaging machines will also be given an automatic monitoring, motion detection, alarm and other workers can, also has safety interlock control, overload protection, and control functions, so that greatly improved the reliability of packaging machines.
4, easy to operate, their efficiency.
Use of mechatronics in packaging machine design, with digital display and a variety of information displays a high degree of concentration, greatly reducing the operating buttons and handle, and a process control functions. So that procedures can greatly reduce the operator can easily be trained.
Conventional packaging machine to use more asynchronous motor drive, in fact more in the light-load working condition, and energy wastage. Mechanical and electrical integration technologies, instead of induction motors with variable frequency motor, by the computer automatically find the best operating point, random frequency conversion motor to adjust the output power can typically save 40% of energy. In addition, it improves the reliability, product quality assurance, and efficiency is also increased.
Mechanical and electrical integration is the development direction of packaging machinery, its application of the time is not long, it has already shown great advantages, with mechatronics in packaging machine’s popularity and promotion, is bound to effect the development of China’s packaging industry to the active role.
