Shaftless numerical control automation of printing machinery (Part 2)

II. Three major scientific and technological achievements in contemporary printing industry

1 CTP technology revolution. The biggest highlight of the development of contemporary printing technology is ctp CTCP digital technology. With the emergence and development of digital printing machine, digital direct plate making machine, digital proofing machine and digital ink-jet printing machine, the traditional plate making equipment and traditional proofing equipment are facing elimination, and the market of advertising industry and rapid printing industry is strongly impacted. The traditional printing equipment used for mass production is also facing unprecedented challenges. A number of machine-made printing machines, plate free printing machines, laser imaging printing machines and inkjet printing machines have been industrialized and occupy a certain market share

2. Digital workflow continues to develop. With the emergence of digital workflow such as CIP3, CIP4, 7df, etc., the design digital information of desktop color system is transmitted to the plate making equipment, and then to the adjustment system of printing equipment. The drupa exhibition in 2004 continues to transmit these design digital information to the post press, connecting the whole production process of printed matter, realizing resource sharing, saving a lot of intermediate links, and becoming the highlight of the new exhibition

3. Numerical control technology is the development direction of printing equipment. The first two scientific and technological achievements are the revolution of printing technology, and the second one is the revolution of printing machinery manufacturing industry, which can also be called transforming the electrical control of traditional printing machinery transmission into digital control. At present, the companies that provide numerical control systems for printing machinery enterprises mainly include Siemens, Rexroth, Lenz and Yaskawa. In addition, FANUC of Japan has not yet entered the printing machinery industry. There are also some foreign machine tool plants, such as Japan's Dami, Mazak, Mitsubishi Hitachi has a suitable pendulum for replacement (the maximum strike energy of the large pendulum is 300j of its own CNC system. There are more than ten CNC manufacturing companies in China, which mainly provide CNC systems for machine tool plants. The main CNC system suppliers are: Beijing Aerospace CNC, Beijing knd company, Shenyang Lantian CNC, Shanghai Kaixing CNC, Nanjing Tsinghua general and xinfangda CNC, Chengdu top and Guangtai CNC, Shenzhen zhongweixing CNC, etc. there are no manufacturers supporting printing machinery Cooperation in this area should be strengthened

in foreign countries, numerical control technology has been widely used. It is rare for web printing machines to adopt DC speed regulation and frequency conversion speed regulation equipment. Only a few enterprises in China have just launched prototypes using this technology, which is still a long way from the process of industrialization

III. speed up the process of automation

since the invention of printing machinery and equipment, in the process of long-term development, it has gone through the stage from manual to mechanization. In modern times, in order to further improve work efficiency and reduce labor intensity, it has taken the road of gradual automation. Automation can be divided into the following stages:

I. semi automated stage - the main work of printing is mechanized, The substrate still needs to be manually input and output. Such as tiger mouth die cutting machine, bronzing machine, silk printing machine that meets the requirements of performance, durability and cost

2. Single machine automation stage - the whole production process of printed matter is mechanized, and people are only responsible for the adjustment of the quality of printed matter and the replacement of operating instruments and auxiliary materials (such as substrate, plate, ink, cutter, etc.). Relevant equipment, such as printing machine, binding machine, box making machine, packaging and printing equipment of various printing methods

3. Automation stage of auxiliary operation - on the basis of single machine automation, the automation level of auxiliary operation continues to improve, such as equipment quality adjustment, automatic paper loading, automatic version loading, automatic ink loading and water, etc. Such as foreign imported roll 764 dollars/ton) cylinder paper printing machine, high-end sheet fed printing machine, etc

4. Online automation stage - on the basis of single machine automation, several equipment in the printing process are connected together and run automatically, such as horse riding binding machine, hardcover linkage line, wireless binding machine, flexographic printing machine, etc

in China, it is best to use oil according to the requirements of the manual. The manual operation procedures that have not yet achieved mechanization in the process of printing mainly include: paper prefabrication, plate loading, cleaning of elephant leather cloth, automatic paper loading and automatic inking of web paper. Some small printing enterprises still use manual page matching, manual folding, manual hardcover of books and periodicals, manual page insertion, manual bundling, etc

the automation level of printing machinery products is low, which is mainly reflected in the fact that the prepress equipment is in the semi-automatic stage. The printing equipment is in the online automation stage, and the automation level of auxiliary operation is low. Post press equipment is mostly in the single machine automation stage, and there are few online automation equipment, which mainly depends on imports

printing machinery and equipment are facing challenges from major foreign manufacturers, and their market share in China is on the rise, especially the high-end equipment is mainly imported. How can we deal with this reality, especially when the current wave of application of CTP and digital workflow is surging, I believe that we should not only pay attention to the development trend of CTP technology and digital workflow, but also practically promote the wide application of numerical control technology, and make efforts to improve the automation level of products, so as to solve the backward technology situation of domestic equipment with high labor intensity, large number of personnel and human controlled quality, Is the top priority.
