Project Description
Beiren Printing Machinery Co., Ltd. has been producing offset printing machinery for nearly 50 years. It is currently the largest manufacturer of offset printing presses in China, and one of the top 500 industrial enterprises in China. It is also one of the first nine companies listed overseas . Beiren's offset press manufacturing technology is closely integrated with international advanced technology, with dozens of technical patents, and always maintains the highest level of domestic offset press technology.
Beiren 45A shaftless tower printing machine is composed of zero-speed paper receiving machine and tower printing unit folding machine. It adopts advanced shaftless transmission technology and is mainly suitable for printing double-sided color newspapers and printing multiple-sided double-sided color newspapers. 1. A single set of red newspapers can realize a variety of different unit combinations according to different needs. The printed newspaper electronic control system adopts the Japanese Mitsubishi programmable controller as the main body of the equipment operation logic control. The German Baumueller company's special printing machine transmission control system performs shaftless transmission control, and is based on the development of Jiusi Automation Software Co., Ltd. The monitoring configuration control software "INSPEC" of Windows Xp @ performs system setting and monitoring.
system design
? Characteristics of system design
1. The system adopts a brand new control mode and system concept, so that the whole system can be combined in a "plug and play" type on the machine, which greatly enhances the flexibility of the system combination.
2. In the operation logic control with the Mitsubishi programmable controller as the main body in the system, RS485 communication is used to start and stop, speed control and fault diagnosis of the ink roller frequency converter;
3. The CCLINK bus links the entire system; the MELSECNET / H network serves as a multi-section system link, and Mitsubishi Industrial Ethernet performs data communication with the higher-level IPC and Baumueller printing press control system.
4. The job management system in the "INSPEC" configuration control software enables the entire system to perform job configuration and management according to the needs of the job, making the operation and control of the entire system more flexible.

This system adopts a layered design. The top layer is the production management system (L3 system) provided by Baoxin Company, which is responsible for order management and production task scheduling management; the middle is the central computer management system (CCC system) provided by Jiusi Company, which is responsible for tasks Analyze and manage subordinate cutting units (a total of 5 cutting units), assign cutting tasks and upload task completion status; the bottom layer is the operation computer system (NC system) provided by Jiusi Company, responsible for controlling specific cutting equipment according to production task requirements Complete product cutting tasks.

â—† The main functions completed by the software system
The configuration control software adopts "INSPEC", which is suitable for different printer systems from single tower to six towers and multiple folding machines. The user can easily adjust the screen configuration and the configuration relationship with the hardware system to Applicable to different types of printer systems.
1. In addition to covering the standard functions of the standard configuration software, it also adds many special functions required by the printing press, such as job management, version control, and ink tracking.
2. The communication with the lower-level controller adopts a universal design, so it is easy to replace the control system of different manufacturers and increase or decrease the monitoring and control parameters. It can be debugged for each part of the system, and each part of the system can be independently started and stopped.
3. The system displays the operation status in the form of graphics and animation. It uses realistic animation display for printing adjustment tasks such as paper roll deviation adjustment, cutting adjustment, ink fine adjustment, and registration adjustment. The operation is simple and intuitive.

to sum up
The image monitoring terminal of Beiren 45A shaftless tower printer system completed by "INSPEC" guarantees the functions of the machine's running status monitoring, operation and machine fault diagnosis. Its printer Special functions such as job management, version control, ink and ink tracking, etc. are highly recognized by users. The research and development of the printing press system began in July 2004, and the prototype was successfully trial-produced in May 2005. As of August 2006, nearly 30 towers have been delivered to users, and they are reliable and stable. They are mainly used in major newspapers including Shenyang Daily, Liaoning Daily, Jiangxi Daily, Zhejiang Daily, and Fujian Daily. In recent years, China's printing machinery manufacturing technology has made rapid progress, and the obvious sign of its progress is that the control part and automation level of printing machinery have been significantly improved. The successful application of "INSPEC" in this field has become a driving force for the industry's automation level. Significant power.
