The Printing Machine Models


If we do not enter the printing industry, perhaps our image of the printing press will only remain on small printers. In fact, printing is a broad vocabulary. More or less of the articles we use around us will involve the printing industry. The following WOW Display shows will be introduced for everyone. Knowledge of large printing machines.

At present, the domestic printing industry's printing machine share: Heidelberg first, Komori second, Gobbo third, Roland fourth, Mitsubishi fifth. Each has its own characteristics and each has specific advantages in different special markets. Here today, we would like for everyone to specifically explain the relevant information of these brands

First: Heidelberg

As the global leader in the offset printing market, Komori has been leading the technological innovation in the offset printing market at a steady pace.

Komori's two most notable offset presses are 1, LIFTHRONE G44 2, and Lithrone A37.

These two sets of product manufacturing innovations are one of the three major directions of Komoris strategic reforms. Made in Japan, interpretation is the pursuit of excellence, and the production of re-innovation goals, but also expressed Komori to improve production efficiency and reduce production costs of the ultimate, endless pursuit. Komori is proud of machining technology that is accurate to micrometers. Each press consists of tens of thousands of parts, and the gears used to drive the machines need to have the same mechanical precision as the aircraft. Lean production and continuous improvement are the high quality of Komori presses. In order to ensure quality, Tsukuba Plant has established three pre-deployed product testing workshops. Each product must be fully simulated and run here. It can only be shipped after shipment. Users can even take samples to the machines they order. . The Tsukuba plant has very few production workers and is highly automated. The use of the AGC (automated truck) is very common. The main production line adopts the Just-in-time philosophy introduced from Toyota. It thoroughly conducts timing, quantitative, and fixed-point management. All processes have detailed action analysis and interpretation to avoid waste and quality differences.

Fourth: Roland

Roland's main products include photo machines (wide-format inkjet printers, inkjet/cutting machines), 3D three-dimensional series products (three-dimensional scanners, engraving machines and mold machines, etc.), cutting plotters (portable, desktop and professional), Metal printers and so on.

AMDEK Corporation changed its name to Roland in 1983 and launched two large-format plotters DXY-800 and DPX-2000. Roland Corporation established joint ventures in the United States and Australia between 1988 and 1990, and entered the cutting plotter market in the same period. In 1988, it launched its first digital cutting plotter PNC-1000.

Combining the experience of R&D of plotters and cutting plotters, Roland launched the first inkjet cutter integrated machine CJ-70 in 1997 and launched the inkjet integrated PC-60 with thermal transfer technology in the same year. In 1998, Roland launched the world's first high-precision 1440dpi six-color wide-format inkjet printer FJ-50, and the 1440dpi six-color wide-split printer CJ-500 appeared one year later. Roland successfully obtained ISO9001 and ISO14001 certifications in 1999 and 2000 respectively.

2000 was an important year for Roland. In addition to the successful ISO certification, the company's shares were listed on the second section of the Tokyo Stock Exchange in the same year, and launched the industry's first 1440dpi eight-color inkjet printer FJ-500. Roland introduced the first solvent-based wide-format photo machine SC-500 in 2001 to open up the outdoor inkjet printing market.

In 2002, for applications in different industries, Roland Co., Ltd. released five PRO II series solvent-based photo machines of different models and sizes at a stretch. As a major supplier of inkjet photo printers, Roland also strives to promote environmental awareness in the industry. In 2003, it launched ECO-SOL eco-solvent ink. Rolands stock rose to the first of the Tokyo Stock Exchange in 2003. In order to broaden the market for more industry applications, the SP-300, a 30-inch inkjet cutting and all-in-one machine for low-volume production, was also announced.

In 2004, Roland further explored the outdoor advertising application market and launched the special wide-format solvent model SJ-1000. This model and even its subsequent models SJ-1045 and AJ-1000 104-inch wide-format inkjet printers were all unanimously recognized by the industry. .

After more than two years, Lianqiang and Roland have become the preferred business partners for numerous indoor and outdoor advertising inkjet customers.

Fifth: Mitsubishi

In recent years, with the improvement of China's automation technology, factory automation has also reached a new level. As a new industrial controller, PLC has unique advantages in its small size, complete functions, low price, and high reliability. It has been widely used in various fields. Keywords: Press Mitsubishi PLC control In recent years, with the improvement of China's automation technology, factory automation has also reached a new level. As a new industrial controller, PLC has unique advantages in its small size, complete functions, low cost and high reliability. It has been widely used in various fields. As the largest printing press manufacturer in China---Beiren Group Corporation, in order to make the product performance stable and easy to maintain, we have adopted a control program based on PLC as the main controller. Since the two-color printing press requires easy operation and high precision, it has more input and output points, and thus dual-machine communication is adopted. The upper machine adopts Mitsubishi FX2N-80MR+32EX+4D/A, which is mainly responsible for the control of the main drive, the control of the clutch and pressure of each unit, and the control of the air pump and the air valve. The lower machine adopts Mitsubishi FX2N-64MR+4A/D, which is mainly responsible for the control of the water roller motor, the speed regulation output of the main drive, and the data acquisition of the adjustment motor. At the same time selected a Mitsubishi 5.7-inch touch screen, mainly responsible for water roller motor speed display, adjustment display, and the whole fault display. The system is reliable, easy to maintain, easy and intuitive to operate, and greatly improves the quality of the offset press and is well received by users. 2 System Structure The upper computer and lower computer use RS485 communication, which is convenient and reliable. For multicolor machines, safety factors are important. In the design, each unit should not only consider the safety control, including the emergency stop of the local unit, and the safety button, but also consider the convenient operation, including the punctuality and reverse point buttons of each unit. Therefore, on the one hand, the input points increase a lot; on the other hand, the alignment is also very inconvenient. The use of dual-machine communication can solve this problem very well. The alignment of each unit can be in accordance with the principle of proximity and enter the control cabinet close to it, which saves the wiring and facilitates the control. Since the printing press is a high-precision machine, the quality of the printed matter depends on the precision of machining and installation. On the other hand, it also depends on the balance of the water circuit, the ink path, and the accuracy of the pressure. Each color group of the two-color machine has a waterway and ink path device. In order to facilitate the adjustment of the water roller speed, each water roller is controlled by one inverter. At the same time, the speed of the main motor also needs to be adjusted by the inverter. Therefore, in order to implement multi-path speed adjustment, we use a Mitsubishi 4D/A digital-to-analog converter, which converts the digital quantity given by the PLC to a 0~10V DC voltage output according to the corresponding algorithm. Multiple speed adjustment requirements. In the printing process, versioning is a more tedious process. Especially for multi-color machines, the accuracy of each set of editions will have a great impact on printed products. If overprinting is not allowed, there will be literal overlap or unclear images in the printed matter. In general, the plate axial adjustment range is -2mm ~ +2mm, the circumferential adjustment range is -1mm ~ +1mm. If you use manual adjustment, you will waste a lot of time and the accuracy is not high. In order to achieve automatic pattern making, we installed a potentiometer on the platen roller and sent the analog quantity to the 4A/D through the potentiometer. After PLC processing, the platen roller's rotation accuracy can be well controlled within the platemaking range. As a new type of man-machine interface, the touch screen has attracted attention since its emergence. Its easy-to-use, powerful functions and excellent stability make it very suitable for use in industrial environments. Users are free to combine text, buttons, graphics, numbers, etc. to process or monitor management of information that may change at any time. With the rapid development of mechanical equipment, the previous operating interface must be operated by a skilled operator, and efficiency cannot be improved. However, using the man-machine interface can clearly indicate and inform the operator of the current condition of the machine and equipment, making the operation simple and lively. The use of a touch screen also enables standardization and simplification of machine wiring. It also reduces the number of I/O points required for PLC control, reduces production costs, and relatively increases the added value of the entire set of equipment. Mitsubishi touch screen and Mitsubishi PLC have very good versatility. They can monitor and modify the program online without having to repeat the plug-in interface.

The price of printing machines varies from model to model, ranging from tens of thousands to tens of millions. So the printing factory does not look at the façade. If you look at the machine, you know if the factory has strength.
