The packaging process includes major processes such as filling, wrapping, and sealing, as well as related processes such as cleaning, stacking and disassembling. In addition, the packaging also includes the steps of metering or stamping the package. The use of mechanical packaging products can increase productivity, reduce labor intensity, meet the needs of large-scale production, and meet the requirements of clean hygiene.
First, the type of packaging machinery
There are many types of packaging machinery, and we introduce several important packaging models.
Pillow packing machine
Pillow type packaging machine is roughly divided into horizontal pillow type and vertical type. It is mainly used for the packing of solid objects and packaging of multiple items. Pillow type packaging machine is a kind of packaging machine widely used in the food, medicine and other industries, and most of the items in daily life are mostly packaged by a pillow type packaging machine. With the rapid economic development of our country and the improvement of people's living standards, the function and production efficiency of packaging machines have faced more choices, and intelligence is one of them.
2 Destacker
The depaler is a machine for layering and destacking various metal cans, glass bottles and heavy plastic bottles. In the packaging industry, with the continuous increase in labor costs and the continuous increase in business volume, the use of destackers has become more widespread. Automated destackers and palletizers can be a good substitute for labor, effectively saving labor costs. At the same time, automated machinery can also allow many packaging actions to be completed efficiently, reducing manual participation, increasing production efficiency and production safety. With the constant development and maturity of technology, the price of unloading machines has become even cheaper. Therefore, there is a wider range of applications.
3 plastic cup molding filling sealing machine
Plastic cup molding filling and sealing equipment means that plastic cup molding, material filling and sealing work are completed on the same equipment or on the assembly line of several adjacent equipment, and a complete marketable product can be produced at one time. The equipment mainly consists of stations for feeding, preheating, forming, filling, sealing, slitting and waste collection. Due to its advantages of low cost, low degree of recontamination during filling, and good counter display effect, the plastic cup filling and sealing equipment has been widely used by domestic dairy manufacturers for yogurt, pasteurized milk and ice cream. And sauce packaging.
4. Blister machine
The blister is formed by a transparent plastic film or sheet, and the product is sealed between the blister and the bottom plate by means of heat sealing, bonding, or the like.
5. Carton forming machine
Carton forming machine is used for carton box loading, automatic opening, spray sealing, and high automation. Suitable for automatic unpacking processes in the beer, beverage, chemical, pharmaceutical and other industries.
Second, the packaging machinery industry automation market development trend
The automation products used in packaging machinery mainly include control systems, transmission control, motion control, human-machine interface and sensors. These include: control systems: embedded products, PLC, IPC, fieldbus; transmission control: inverters, DC Speed ​​control; motion control: servo, stepper, motion controller; human-machine interface: text display, touch screen, tablet computer electrical components and sensors: photoelectric switch, temperature sensor, pressure sensor, travel switch, etc. are the same as other mechanical products.
1. Technology to realize the automation of packaging machinery
The packaging machinery industry is also a major industry for the application of automation products. In the application of the controller, a small-sized PLC is mainly used, and some high-end and complicated equipment also use a medium-sized PLC. In the human-machine interface, the touch screen is the main method. Since there are a large number of small and simple machines in the packaging industry, each machine will be equipped with a distribution box, so the low-voltage electrical product market has a large capacity. Most packaging machines use low-power inverters. In addition, many packaging machines, such as palletizers, require precise positioning functions, and therefore a large number of servo products are used.
In terms of data, we have cross-cutted these two dimensions so as to describe the scale and subdivision of the automation market more meticulously.
The data only includes PLC, HMI, low-voltage inverter and servo, not including low-voltage electrical and low-voltage motors.
2, inverter market
Low-voltage inverters have a very wide range of applications in packaging machines. The transmission market is huge, with low-voltage inverters accounting for 4.2% of the overall market. There are a lot of manufacturers of low-voltage inverters, from abroad to domestically, there are applications in the field of packaging machinery. However, it is still dominated by foreign brands. Mitsubishi ranks first in the packaging machinery industry. The rest are companies such as Yaskawa and Fuji. The application of low-voltage frequency converters has become increasingly widespread in the field of packaging machinery, but at present energy-saving is still the main focus. The energy-saving and consumption-reduction of the packaging machinery industry is also the subject of the future development of the packaging machinery industry.
3, PLC market
The main controller of the packaging machinery industry is still dominated by PLC, and the PLC market of the packaging machinery industry accounts for 7.0% of the entire PLC market. In the PLC market of the packaging machinery industry, in terms of quantity, the number of small PLCs is the majority, followed by medium-sized ones, and there are very few micro and large PLCs. Because of the application of small and medium-sized PLCs, there are many similarities between the competitive landscape of the packaging machinery industry and the pattern of the small- and medium-sized PLC market. The shares are concentrated in Mitsubishi, Omron, Siemens and Delta. Stable structure: Delta, as a new manufacturer, has grown rapidly in recent years and has become an important supplier of small PLCs. In 2013, the various categories of the packaging industry continued to grow and completed the packaging of China's consumer goods and the packaging of exported goods. The recovery of the entire packaging industry was obvious and exports resumed. With the growth of the industry, PLC's demand has also continued to grow. PLC market growth is relatively stable, basically in line with the growth of investment in the packaging machinery industry.
4, servo market
Servo has a very wide range of applications in the industrial field. As an important industrial industry, packaging machinery has a huge market, and servo accounts for 11% of the overall market. In the packaging machine industry, servo manufacturers Panasonic, Delta and Yaskawa accounted for the top three market share, respectively 16.80%, 9.70%, 8.50%.
China's packaging machinery industry started relatively late, its foundation was relatively weak, and its technology and scientific research were insufficient. While mechatronics has become the mainstream trend in the industry, the packaging machinery industry will continue to grow rapidly in the next few years, and the demand for servo systems will also grow at a high speed. Packaging machinery companies are mainly concentrated in the Yangtze River Delta (extending to Wenzhou), Pearl River Delta (including the eastern part of the province) and other provinces, which will also be the future of servo
At present, the bottom-end market mainly needs manufacturers to be close to the market to understand the user's product structure and application fields, and to launch products with relatively simple and practical functions and lower cost. With the needs of users continue to develop. Servo drive manufacturers are facing the challenge of the ever-changing demands of users and OEM manufacturers. In order to win the future market, in the future, the servo market will grab a place, the manufacturers need to master the preparation of core software, no longer rely entirely on imports, increase investment in high-end technical human resources, gradually improve product maturity, improve marketing and customer service system, Form brand influence.
After the financial crisis, especially in the foreign market, the demand for automation of packaging machinery has increased. Export-oriented packaging machinery manufacturers will be the new breakthrough for servo products. The financial crisis is, to some extent, a good news for China's packaging machinery industry. Because of the macroeconomic downturn, foreign packaging companies have adopted cheaper Chinese equipment to replace expensive equipment in developed countries in order to save costs. Then the gradual recovery of the global economy, China's packaging machinery automation level will not be obvious disadvantages. Therefore, improving the degree of automation of products has become a top priority for China's packaging machinery industry. Domestic manufacturers can pay more attention to packaging machinery companies that export more and seek new market breakthroughs.
