1 Introduction In recent years, rapid economic growth and improving people s lives, as one of the traditional industry packaging industry, showed a trend of rapid development, is universally expected to " sunrise industry ", is followed by substantial growth in demand for packaging machine applications. Mechatronics has become increasingly concerned about all aspects of it to improve people s lives, improve efficiency, save energy and reduce material consumption, and enhance their competitiveness plays a vital role.
Today, the rapid development of mechatronics and automation technology, packaging machines have been automated. Semi-automatic packaging machine is generally divided into two kinds of packaging machines and automatic charter, by the artificial supply of packaging materials (containers) and the contents, but can automatically complete the other is called semi-automatic packaging machine packing machine processes, automate key processes, and other ancillary packaging Packing machine processes as automatic packaging machine.
This paper introduces a new generation of small companies and facilitate the integration PLCDXD time series packaging machine applications, the application to improve the automation of packaging machines to take a good result, good promotion prospects.
2 System Overview
DXD series packaging machines are widely used in food, medicine, cosmetics, chemicals, tea, seeds, granules, flakes, powder and semi-fluid-like packing material. Packaging Machinery Manufacturing Co., a Beijing production of DXD Series Automatic Packaging machine and filling machine professional manufacturer, its production DXD Series Automatic Packing machine and filling machine sales at home and abroad, to the user generally well received.
And the Belgium Technical Corporation PLC DivisionOperation personnel to run this type of packaging machine environment and repeated inspection of the site, fully taking into account the circumstances at the scene of different domain characteristics (Russia, Guangzhou, etc.), reliability, stability and so a lot of work is proposed based on HOLLiAS-LEC G3 small integrated PLC control system. The running results show that the G3 Series PLC control system to achieve the desired effect, greatly increased the level of automation equipment.
DXD Automatic Packing machine required feeding, bag making, filling, sealing, cutting, tearing notches automatic completion of packaging speed, bag length can be adjusted. By HOLLiAS-LEC G3 PLC control DXD Automatic Packing Machine is a mechanical and electrical integration, photoelectric detection, automatic tracking stepping motor and other functions into one multi-purpose correcting automatic packaging machine, packaging machine with the electric eye tracking, PLC controlled, continuously variable correction and other functions, measurement precision, consistent with industry standards, with stable performance, convenient operation and maintenance, high efficiency, ensure the stability of bag length, beautiful graphics.
Process requirements, DXD Automatic Packing Machine with PLC for automatic control, including the coordination of the two most critical step motor to run. Use a 24-point CPU Module LM3106 as the core of the whole control system, LM3106 can handle normal DI, DO, AI, AO point, also includes three-way high-speed pulse counter inputs and two high-speed pulse output, the output frequency of up to 20KHz. Shenzhen Electronic Co., Ltd. used machine 5.7 "STN LCD touch screen MT506L blue as the man-machine interface.
3 PLC control system design using DXD Automatic Packing Machine can automatically bag, automatic feeding, automatic measurement, automatic packaging and many other functions, and can carry out real-time monitoring of the production process, complete the automatic diagnosis, automatic alarm and data upload and so on. Process requirements, DXD Automatic Packing Machine control system consists of man-machine interface operation and display systems, bag control systems, to sendE8 traffic control system: feeding measurement start signal ON, start feeding, feeding with servo motor touch screen to set parameters of work. PLC filling amount of real-time detection, servo motor speed measurement value is different from the completion of filling, all-speed filling, trace fill, fill the end of the feed in place. All feeding process, the touch screen real-time tracking, display all data changes, if there is fault (such as motor block transfer, etc.) or unreasonable data appear, the machine will stop, and forced the touch screen display and alarm, and send up positioner fault content. Parameter settings see Table 2.
Packaging and shear control system: to ensure the safety of the machine and, first of all to judge the rationality of packaging and shear data. If the data is not correct, packaging machine is protected and the contents of the touch screen displays a warning. If the data correctly, PLC real-time data collected to calculate the feed bag after the end of the output package. Touch screen contrast setting shear values, conditions to meet the output Q0.0 complete cut. Packaging machine packaging and bag the shearing process to ensure the process is not carried out, must be interlocked.
