Automated folding technology has a history of more than 20 years. As far back as the Drupa show in 1978, Heidelberg company took the lead in displaying the first remote-controlled folding concept machine. In the following years, Shoei and Mahtias Bauerle (MB) finally formed the first computer. Control folding machine. But today, this technology is really started, and for most machines, their folding functionality is still limited. Chris Foynes, marketing manager at Heidelberg (UK), spoke about this situation: “At present, the degree of automation of the machine can reach 30%, which can reduce the overall work-ready time by half, and reduce errors and calculation time. Small or digital printing is extremely advantageous because small digital printing requires only a few formats, one-step molding machines are suitable for this working environment, but for large-scale commercial printing, the function of such machines is obviously insufficient, because large enterprises need Dealing with various sizes, materials and foldings of various types and patterns, the preset several or standard formats are far from meeting the production requirements.†“The increase in the degree of automation not only reduces the level of proficiency but, on the contrary, they The proficiency of the operator is more demanding, and the printed paper is changing every moment, and the ink, coating, glue, etc. will cause the paper to be deformed, and if the paper properties and the performance of the folder are not well understood, it cannot be done well. This part of the work. Artificial intelligence can indeed speed up production schedules and reduce errors, but it can only help." With different machines, CNC systems generally account for 15% of the total investment in equipment. This requires printers to consider trade-offs between investment and yield. Heidelberg's new DCT2000 folding machines are more automated, but the systems are also more complex.†Drupa show this year In Heidelberg, a more advanced 50 x 70 cm Stahl Topline fence folding machine was introduced. It can be transmitted through CIP3 files, set up post-press processing programs before printing, and directly complete various folding functions. The machine contains 81 sets of predetermined programs. After inputting the length and width of the paper, each parameter can be calculated and set independently, and the grid start and side guide devices can be controlled to complete the scheduled tasks. In fact, Foyins believes that this kind of machine is too advanced and advanced to the point where users are not well used. Roger Cartwright of the Herzog+Heymann (UK) company also shared the same view. He said: "Automation is certainly useful, but the scope is limited because it depends on the number of jobs and the frequency of replacement. Only those settings are the same, The same advantages, such as material, registration, format, etc., are all reproducible and can show advantages over manual operations.†“H+H's market is small folding and straight-mail letters, and completely repetitive work is relatively ineffective. In many cases, automation is not very useful. Although automation can increase the speed of work, many of the nuances need to be continuously adjusted, and the machines are much more clumsy in this respect.†“Users will also feel that the investment in automation may not be worth the candle. On the one hand, after the company had been independent for a year now, it was supposed to be a big step forward in machine automation, but it was precisely because of this market pressure that the company was forced to insert in the non-automation field.†Indeed, now The attitude of the market is still slowly moving towards automation. According to a report by Mike Big, head of Smyth Horne, more than 12 companies across the UK have added Shoei's computer-controlled folding equipment. He also hopes that the SetMatic B2 type Multimaster CAS folding machine MB company launched in Drupa will also appear in its company. This B-type machine is only about 10% more expensive than a traditional A-type machine. With his introduction, this kind of machine has a high degree of automation. Once a folding style is selected and a folded paper is fed into the machine, the machine can automatically calculate the weight of the paper and set the corresponding folding plate, folding roller and counter. The parameters such as the turret, and then "a push button", the machine can be folded beautifully beautiful, without manual adjustment of the print. The whole process is basically no waste, and it is very suitable for digital printing. According to Beagle, the Shoei and MB machines are similar in function but have different market positioning. The MB machine has a low requirement for the operator and is suitable for digital printing and letter straightening. However, the Shoei machine is advanced. When the B1 frame is folded into 16 or 32 pages, the operator must require considerable skills. Through the computer system, the entire setup work can be completed within 5 minutes, which is only 1/9 of the original time. As another provider of the folding market, MBO Inc., the machines it produces include some Other functions in addition to basic computer control functions. Such as Rapidset machine, can adjust the folding board and so on through the computer settings. From January this year, MBO will provide Navigator for mid-range users. The model that was once exposed at Drupa is an artificial intelligence machine. It has an interface that allows it to be controlled via CIP3 data transmission and enables remote error diagnosis and error recovery. From this perspective, the current folding technology is developing in two directions. One is a complete set of automation for single machines, and the other is online automation for continuous machines. The former is represented by MB and Shoei, who use MBO and Heidelberg as forwards. The reason why these two directions are produced is nothing more than the characteristics of the respective companies. But there is one undeniable fact: that is, machine automation is the general trend, and the choice of one or the other machine should be based on the user's specific circumstances.
