Over the years, Civiemme has introduced various types of products that can meet the various needs of rotary printers.
The production speed of rotary printing presses is generally above 40,000cph. Since 2001, Civiemme has installed 40 post-press equipment systems on the European market to handle the output of 64-page rotary printing presses. The postpress system is used to process 48 pages of printing press job output.
The following are some application examples of printing manufacturers:
European market case study
Pozzoni of Italy
Pozzoni Group is a leading domestic printing company in Italy. Recently, three new Roland Lithoman IV64 printing presses were added, which increased the roll paper production capacity by 60%. At the same time, it was also equipped with the latest solution of Civiemme. Disposal of signatures. The company's goal is to further improve processing capabilities and grow into a leading printing company across Europe.
These imported rotary presses are mainly used to print catalogs, magazines and advertising products of different formats and pages. The Lithoman press will be installed between mid-2004 and mid-2005.
Civiemme ’s equipment will handle the product stacking and signature classification of the four delivery devices (two magazines, a tabloid, and a DP) of each printing press at the same time. There is a transmission system on the top, with a steering door and a job flow conversion structure to change the direction. Through this transmission system, the printed paper can be transferred to Civiemme's post-press equipment.
Both Lithoman presses will also be equipped with the same post-press equipment solution. Many processed products, such as leaflets and advertising products, will be cut by the RT 550 rotary cutting machine for three to four sides. The cut products are stacked by the CS 350 compensation counting stacker. The unique gap compensation equipment is installed on the stacker to ensure that the work flow is continuously and smoothly transferred to the upper positioning area, and the printed products are stacked there. On the CS 350 paper delivery system, the electronic module unit (BU350) can very stably fluff the paper stack, and then manually or automatically palletize the stack. This way, the perfect quality of the printed products can be maintained, and the use of adhesive tape can be avoided.
Book strapping uses a different stacking solution, which consists of two ST 420/120 bundling and stacking equipment to form 1200 mm thick book bundles. This stacker is specially designed for fast web printing equipment, which can quickly produce book bundles in a few seconds. In Pozzoni, this stacker is also equipped with a fully automatic double packing system: when the first packing unit is broken, the second packing unit is automatically started as a backup, which guarantees the packing process and production. Continuity of the process.
The bundles processed from the two ST 420/120 bale stackers and the book stacks processed from the CS 350 compensatory stacker will be sent to a separate stacking device: PL-Robot 250 . This stacking robot is installed with other equipment for fully automated stacking process production, including tool conversion and clamping for book bundles and paper stacks. The speed of PL-Robot 250 is to stack 144 book bundles per hour and 800 bales per hour.
The third Lithoman printing press will also be equipped with a post-press equipment system specifically for bale production. In this case, Civiemme will provide a special robot specifically for palletizing and stacking the book stacks processed by the ST 420/120 stacker.
The Pozzoni Group of Companies is very pleased to choose this post-press equipment system for their new 64-page printing press. Its technology and special structure allow for high-volume production and processing, providing great flexibility and efficient production, while , Its compact structure also saves a lot of space for their plant.
Kraft-Schlels of Germany
A German printing house, Kraft-Schlels, has introduced a Manroland Lithoman IV 48-page web press since March 2003. Kraft-Schlels and Strohal Rotationsdruck, a well-known Austrian printing company, jointly carry out joint production. They have more than 10 rotary offset printing equipment, which can complete the production from 16 to 128 pages, and provide commercial prints and magazines to users. They set their investment focus on advanced rotary printing technology, aiming to provide users with high-quality products and fast distribution services at the leading European level. So the post-press equipment system they chose for their new Lithoman press also followed the same principle.
Civiemme's fully automatic post-press equipment system can handle the output of one or two folding paper-feeding equipment, with a high degree of flexibility, it can fully keep up with the speed of the printing press, and can maintain perfect print quality. The two job streams transferred from the two folding paper feeding devices will be stacked on the rotary cutter to perform three-side or four-side cutting process. This precise cutting system allows the cutting of two job streams simultaneously, and can also be processed separately. The conveyor located on the top of the cutting machine will transfer the cut work to two CS 350 H compensation counting stackers equipped with high-level paper feed units. Civiemme's compensation stackers can produce high-speed paper stacks. The speed can reach 100,000cph, and the processing method is also very stable. Then the book stack is released or strapped by a separate two-station palletizing and stacking device PL-Robot 100 DUAL. This robot is capable of palletizing and stacking operations from one or two compensating stackers. It is connected to a gripper and can extract one or two stacks of paper according to different product formats. The stacking speed of the pallet can exceed 800 bales per hour.
The whole process of post-press processing is automatic. The operator only needs to pre-adjust the stacking equipment according to the size of the job to be processed, and pre-set the palletizing data and job schedule.
Einsa in Spain
Einsa Ediciones Informatizadas SA of Spain mainly produces phone books, and it is also a leading printing company in Europe.
Einsa and Civiemme have been cooperating closely since the late 1980s, actively developing highly flexible and highly automated paper stacking equipment and palletizing equipment.
Three 96-page KBA C618 presses from Einsa Alcobendas have been equipped with Civiemme ’s baling and stacking equipment system since 1999. Like its KBA printing press, the later introduced Heidelberg Sunday M4000 / 64-page printing press (installed in 2003) also installed a similar post-press equipment system with two ST 420/120 baling stacks Paper machine-used for high-speed production of 1200 mm thick signature bundles, in addition, there is a PL 86 DUAL packing and stacking equipment, which can serve two paper stackers at the same time.
Einsa is still investing in high-volume web presses. It later introduced a KBA C818 64-page printing machine, which was installed and used in July 2004 and can produce 128-page products. The Civiemme post-press equipment system it is equipped with is similar to the output processing of the M4000 press. This system can handle a wide range of products-A5, A4, A3, Double Parallel and various formats, is a highly automated solution, providing users with effective workflow and efficient production.
