1. Packaging Industry Development Overview
Packaging machinery is able to complete all or part of the process of product and packaging machinery. Packaging process, including filling, wrapping, sealing and other major processes, as well as before and after the associated processes, such as cleaning, stacking, and demolition. In addition, the package also includes the measurement or in the processes of stamping of packages.
China's packaging industry is relatively developed countries such as Japan and the United States lags behind, with a very large potential for development. In 2005 China produced a total of 93,000 sets of various packaging machinery, the output value 55.0 billion, a small increase over the 2004 decline. According to Food and Packaging Machinery Industry Association statistics, China currently has more than 3,600 packaging machinery manufacturers, but the value and sales of over billion is now only 20.
Of domestic packaging machinery company mainly produces relatively simple equipment, high-end equipment, rely mainly on imports, only a few domestic enterprises to provide complete production line.
2. Automation products in the packaging industry, the use of
1.) Overall
Packaging machinery automation products are mainly used in control systems, motion control, motion control, man-machine interfaces and sensors of these categories, including:
Control system: Embedded, PLC, IPC, on-site bus; transmission control: inverter, DC drive; motion control: servo, stepper, exercise control;
Man-machine interface: a text display, touch screen, tablet PCs electrical components and sensors: photoelectric switches, temperature sensors, pressure sensors, trip switches, etc.
2.) Main Automation Products
i.) Controller
Food and packaging machinery to use controllers varies considerably, large-scale production line used in the field bus technology, control points, up to several thousand, mostly used on a stand-alone PLC or a dedicated controller, low-end devices are part of the relay control way, and more small devices do not use any electronic controller, the overall domestic packaging machinery is only about 10% of the use of an advanced controller.
From the best IPC performance, highly scalable, rich software resources so that it can develop more applications, at present mainly used for large-scale equipment management and communications. PLC system in less than 5 years will still be the mainstream of packaging machinery controller; relay the mainstream as a former controller, will continue to extend the low-end market, despite the market decline, but in three years will not be eliminated in the packaging industry.
According to China's Industrial Network Survey in 2005, China Packaging Machinery controller market for 3 billion, of which 200 million yuan less than the market PLC.
ii.) transmission drive products in the packaging machinery used primarily to adjust the speed of the main processes in the production process and control the motor speed of cyclical changes. For most packaging machinery, the converter will not necessarily selected electrical products. Although more and more packaging machinery manufacturers to design the drive inverter-based program, but only a handful of users. Therefore, unless you must use the inverter occasions, packaging machinery manufacturers to consider low frequency converter. Inverter relatively low utilization rates in the industry, in large standard gauge machine and packaging production lines have greater room for development. According to China's Industrial Network Survey in 2005, China's packaging machinery industry driving the market is about 2 billion, mainly small-scale power from 7.5KW inverter products below.
iii.) Motion Control
Motion control products in the packaging machine is mainly on the application of precise position control and strict speed synchronization, for loading and unloading, transportation, marking, stacking, stacks, etc. unloading process.
The industry may use motion control products, packaging machinery mainly include: carton production line, automatic packaging machines, vacuum packing machine inflatable, plastic laminating machine, composite flexible packaging machine, liquid packaging machine, packaging robot, unmanned operation of packaging production equipment, packing / bottling equipment, cleaning, drying equipment, molding, filling equipment, sealing, capping equipment, weighing, packaging equipment and aseptic packaging equipment.
Motion Control Products last three years, the application in the packaging machinery industry developed rapidly, according to Chinese industrial control network surveys, in 2005 the industry's campaign to control the market closer to 1.5 million, of which slightly more than 100 million yuan servo market.
Due to the rapid development of China's packaging industry, the domestic will require more high-end packaging machinery, motion control products will also be in the industry greater room for development.
iv.) man-machine interface, HMI packaging machinery in order to display text-based, often used in conjunction with the PLC or microcontroller to set the process parameters, monitoring equipment running status, recording equipment production history. A small number of high-end machines use the touch screen.
According to China's Industrial Network Survey in 2005, China's packaging machinery HMI market is about 4,000 million, of which slightly more than 3,000 touch-screen market million. As prices continue to fall, packaging machinery industry HMI market in 2004 compared with a relatively large decline. |
