introduction:
According to relevant statistics, with the rapid development of China's economy and the improvement of people's quality of life, the demand for convenience foods such as microwave food, snack foods and frozen foods will continue to increase, which will directly drive the demand for related food packaging, Chinese food. The packaging machinery industry will maintain positive growth for some time to come. It is estimated that during the "11th Five-Year Plan" period, the total output value of China's packaging industry is expected to reach 450 billion yuan, and maintain an average annual growth rate of 7%. From 2011 to 2015, the total output value is expected to exceed 600 billion yuan, and the average annual growth rate is maintained at 16%. By product classification, the output of China's paper packaging products will reach 36 million tons by 2015, 9.46 million tons of plastic packaging products, 4.91 million tons of metal packaging products, 15.5 million tons of glass packaging products, and 1.2 million sets of packaging machinery. It is expected that the circular economy will become the main mode of development of the packaging industry in the future, the recycling of packaging resources will be industrialized, the green packaging materials will be vigorously developed and developed, and the packaging infrastructure industry will also accelerate development. The development level of a national packaging industry and its packaging design research and development concept are important indicators of the degree of civilization in the country's economic life. The packaging industry not only covers the design, production, packaging and printing of packaging products, the supply of raw and auxiliary materials for packaging, packaging machinery and packaging equipment manufacturing, but also its packaging products are also involved in the first to third industries. A link. Disposal, recycling and recycling of used packaging products is a permanent social responsibility of the packaging industry. Therefore, the development of the packaging industry is closely related to the integration of the global economy and the sustainable development of human society. As a “sunrise industryâ€, the packaging industry will inevitably have an inestimable effect on the global manufacturing development and the international circulation of its products.
However, at present, the degree of automation of packaging machinery in China is not high, and the technical level needs to be improved compared with other packaging powers. Therefore, we must vigorously develop the automation level of packaging machinery, improve production efficiency, and improve the grade of products, so that we can stand in an invincible position in the fierce international packaging market competition. Let us introduce the application of the Small Integrated Controller (OCS) from the United States in the packaging industry.
First, the application of integrated controller OCS in the granule packaging machine:
Granular automatic packaging machine is suitable for automatic packaging of loose, non-adhesive coarse powdery and granular materials in pharmaceutical, food, plant seeds, cosmetics, chemical and other products, such as: granules, pellets, monosodium glutamate, white sugar, soup, cereal, etc. The automatic granule packaging machine can automatically complete all tasks such as metering, bagging, filling, sealing, cutting, counting and hot pressing batch number in the packaging process. It is the production automation of the pharmaceutical, pharmaceutical, chemical and other industries to improve production efficiency. Preferred equipment. A packaging machinery manufacturing company in Beijing is a professional manufacturer of automatic packaging machines and filling machines. Its DXD series automatic packaging machines and filling machines are sold at home and abroad, and have been widely praised by users. After carefully studying the working principle of the packaging machine, Horner technical engineers proposed a control system based on the XLE103 small integrated PLC. The product appearance is as follows:
DXD automatic packaging machine requires automatic filling of filling, filling, bagging, sealing, shearing, tearing, hot pressing batch number, etc. The packaging speed and bag length can be artificially adjusted. The DXD automatic packaging machine controlled by XLE103 is a multi-purpose automatic packaging machine integrating PLC controller, man-machine interface, temperature PID control, high-speed I/O, stepper motor control and other functions. The packaging machine has automatic Feeding, high-speed counting, adjustable bag length, self-adjustable temperature, stable performance, convenient operation and maintenance, high efficiency, etc., ensure the length of the bag is stable and the figure is beautiful. According to the process requirements, the DXD automatic packaging machine adopts XLE103 for automatic control, including the coordinated operation of a key stepping motor. The XLE103 is a highly integrated integrated controller that integrates 12 digital inputs, 12 digital outputs, 4 high-speed counter inputs up to 10KHz, and 2 channels of 100KHz PWM (high-speed pulse) output. The 14-bit analog input can support 8 PID digital adjustments. In addition, two serial ports are integrated to support the MODBUS protocol and other serial protocols. And programming software is free, programming cable users can make their own.
It has been proved by practice that this OCS controller can completely control the various actions of the granule packing machine and achieve the purpose of reducing cost and improving efficiency. It is a good precedent to increase the added value of the granule packing machine.
Second, the application of integrated controller OCS on the buffer machine:
With the rapid development of the industry, the demand for packaging materials is increasing, especially for the packaging material foamed polystyrene (EPS) with cushioning properties. The cushioning packaging material belongs to a disposable packaging material with a short life cycle and “used and thrownâ€, which can become garbage in an instant, and the negative impact on the environment is obvious. The packaging of household appliances, electronic instruments, glassware and other products has always used EPS. However, since the waste of plastic foaming materials cannot be biodegraded in nature for a long time, causing serious "white pollution" to the environment, it has been banned in many countries. China will also gradually ban use. Therefore, the use of wrinkle kraft paper is an economical and easily available cushioning material, which is characterized by stable surface properties, is not easy to generate dust, easy to process, good plasticity, and its cushioning effect is mainly achieved by pressing wrinkle kraft paper, which can be light. The product to be installed provides a good cushioning effect. The following is a detailed introduction of the pleated kraft paper production equipment-buffer packaging machine with integrated controller OCS as the core control. The appearance of the buffer is as follows:
The controller of this device is a small integrated controller XLE independently developed by Horner Company of the United States. The engineers of Horner decided to select XLE103 as the control part of this equipment after careful study on the characteristics of the buffer packaging machine. The controller measures only 96mm x 96mm x 58mm, making it ideal for small systems. It also integrates 12-point DC input (four of which can be configured as high-speed counters); 12-point DC output (two of which can be configured) For pulse width modulation); 2 analog inputs; 2 serial communication ports; support TF-flash card; more importantly, it comes with a 128×64 graphic LCD. These functions fully meet the requirements of the buffer machine, and the appearance of the controller product is as follows:
It has been proven by practice that XLE103 fully meets the process requirements of the buffer packaging machine and can be automatically adjusted according to the working conditions to achieve the highest energy efficiency of the equipment.
Third, the application of integrated controller on the sealing machine
At present, China's food safety and hygiene standards are increasingly strict. Therefore, vacuum packaging must be used in the production and transportation of food. This requires vacuum packaging of foods using sealing machinery. Here is a brief introduction to the application of the integrated controller XLE on the vacuum sealing machine.
The two main control points of the sealing machine are the control of the vacuum inside the bag and the sealing temperature. XLE detects the vacuum in the package by receiving the signal from the vacuum sensor, thereby controlling the start and stop time of the vacuum pump according to the set value of the operator, and performing heat sealing immediately when the vacuum in the package reaches the set requirement. Thereby, the shelf life of the food in the bag can be maintained. Therefore, the requirements of the controller are very high, not only the analog signal is collected from time to time, and the comparison is continuously performed. According to a special algorithm, the vacuum inside the bag is kept in a dynamic balance. In addition, XLE itself has 32 relatively independent PID algorithm adjustments, PID control based on the temperature signal collected by the thermocouple has achieved good results.
