Printing machines generally have a variety of drive shafts, but today the complex mechanical long axes of the printing press are being replaced by electronic long axes in the form of separate AC motor drives. In 1994, Rexroth Indramat, a German professional drive and control supplier, first introduced non-shaft drive technology to the printing industry.
Keywords: Control System Flexo Printing Machine New Concepts Axis Independent Drive Technology The introduction of the concept of "shaftless drive" presses was primarily aimed at reducing the cost of development, production and sales of printing equipment, followed by printing and decorating processes. Provide greater production flexibility.
The German company is still one of the market leaders of this technology so far. According to Ralf Bergmann, Industry Manager of Rexroth Indramat, since the technology was born in 1994, they have been used in thousands of models worldwide. The printing presses and paper processing equipment are equipped with this shaftless independent drive system, most of which are equipped on newspaper presses, such as "China Youth Daily", "Las Vegas Review Journal", "Koelner Express" and "Daily Mail" etc. Newspapers use printing equipment equipped with such a system.
Today, the SYNAX 200 drive and control system from Rexroth Indramat is becoming the basis for the innovative design and development of flexographic printing presses for packaging. In recent years, almost all major printer manufacturers have accepted such shaftless independent driving technology, and thus developed a number of new types of printing presses. For example, Rexroth Indramat has completed the drive and control solutions for the seven-color, non-shaft-driven flexo presses and satellite flexo presses.
Drive and control system with electronic long axis The SYNAX 200 drive and control system replaces mechanical devices and mechanisms that are still frequently used but are relatively expensive, such as mechanical gear boxes, universal joints, transmission shafts and cams. With digital intelligent servo drive and precise electronic synchronization system, there is no need to provide additional auxiliary drive systems for different gearboxes or for special functions.
All necessary functions for adjusting the drive status result can be adjusted by setting different parameters of the printing press. To achieve this goal, the SYNAX 200 includes an electronic long axis, an electronic cam, a take-up controller, a tape tension controller, and a register controller.
"SynTop" as a command and diagnostic tool, can guide the user through the monitor's online help, directly enter the desired content and set parameters, thus changing the original long-consuming, high-cost programming.
The SYNAX 200 control system calculates a synchronized virtual “electronic axis†position for each individual drive system, and transmits the optical fiber to the printer's axis-free, independent drive, according to the expectations of the standardized SERCOS drive interface (IEC 61491). On the system, it is completely free from any interference. The position (or phase) control of each axisless independent drive system is the same, ensuring that the entire press runs synchronously in the printing process.
Non-shaft drive technology will be the future direction The use of electronic drive and control systems will not only replace and minimize the mechanical components, but will also ensure that the modularity of the press is guaranteed by high standards, resulting in higher repeatability and lower manufacturing costs. The printer can also increase the flexibility of printing and improve the overall printing production level so as to obtain higher printing machine utilization and better print reproduction quality. And when printing presses are turned on and off, printing errors can also be reduced.
It can be predicted that in the future, the productivity of printers and the productivity of printers will depend mainly on the control solutions used. The use of a shaftless stand-alone drive system such as the SYNAX 200 in printing and processing equipment will help to better develop the various functions of printing and processing equipment, and better utilize its flexibility, accuracy and high-accuracy synchronization. , And these will become the universal requirement for packaging printing users. Since the solution of the SYNAX 200 system offers great advantages and flexibility over competitors, it actually reduces the cost of the press.
