Description

The invention relates to a rotary printing press system according to the preamble of claim 1.

In order to be able to cope with the high cost pressure in the printing industry, rotary printing presses with a large product variability are required, which make it possible to achieve high utilization and thus economic efficiency by producing different products. This results, for example, in weekly recurring production requirements with several daily product changes. The products to be produced to achieve a high utilization of a rotary printing press can be both with regard to their composition of heat and / or coldset webs and placement of the respective webs in the product, as well as with regard to their format, such as page size, page number, folding arrangement, strongly different.

Further requirements for rotary printing presses are low investment, operating and production costs. The investment costs are formed, among other things, by the size of the required production premises or halls, whereas the operating costs are composed, inter alia, of personnel costs for the operation of a rotary printing machine as well as personnel expenses for product changes. In addition, downtimes in the event of disruptions occurring, caused, for example, by web breaks, are also included in the production costs.

To be able to produce a product with heatset webs or partial webs that can be placed anywhere in it, the WO 2007/020288 A1 a rotary printing machine, which is a first, intended for the production of newspaper products machine line with at least two printing towers and one aligned with the Printing towers arranged first former hopper assembly, and a second machine line with at least one second printing tower, arranged in the second machine line in alignment with the second printing tower heatset, and arranged in alignment with the second printing tower and the heatset, the second formers. The first machine line is rotated by 90 ° with respect to the first machine line. A heatset web printed in the second machine line and guided by the heatset is deflectable by 90 ° by means of a turning bar arrangement from a transport direction perpendicular to the first machine run and can be guided in a transport direction parallel to the first machine run.

A disadvantage of such a rotary printing machine with mutually perpendicular machine lines, in which one or more heatset webs or partial webs can advantageously be placed anywhere in a product, their large space requirement is associated with high investment costs for the production premises or hall.

By the WO 2004/024448 A1 is a rotary printing machine with a plurality of printing units, at least one heatset and at least one folding unit known in which at least one printing unit is arranged relative to the axial direction of its cylinder next to another printing unit. The longitudinal direction of the heatset is arranged transversely to the axes of rotation of at least one cylinder group bounding a pressure gap. In each case, a printing unit and a heatset form one of the at least two parallel machine lines. The at least one folding unit is arranged transversely to the machine lines between them.

A disadvantage of such a, a small footprint or compact external dimensions having rotary printing press, is their complex web guide, in each product to be produced a deflection of the webs or partial webs or existing of several webs or partial webs strands must be done via a turning bar assembly to a folding unit, resulting in the resulting long railways to increased risk of breakage, associated with large downtime, production losses and thus high production costs for the products to be produced with such a rotary printing press.

From the DE 10 2004 051 263 A1 and the US 5 647 582 A are rotary printing machines with two parallel machine lines known. In this case, a printed in the first line substrate of the second line can be fed to produce a common printed product. Dryers are not provided in this system.

The invention has for its object to provide a rotary printing machine system.

The object is achieved by the features of claim 1.

Accordingly, a rotary printing press system comprises at least two in the form of machine lines arranged in parallel, optionally separated or jointly producing, in each case at least one printing unit for printing on one or both sides of a material web, web and a line arranged in line with the at least one printing unit, the at least one printing unit subsections containing ordered heatset. Each subsections has a folding unit arranged in the respective machine line and comprising at least one folder former, so that heat and / or coldset webs printed by the machine lines in a main production can each be fed to a folding unit in a deflection-free manner. In addition, each subsection has a turning bar arrangement for the individual transfer of printed in a machine line heat and / or coldset webs or partial webs in at least one parallel machine line, so that in other productions in the subsections independently printed heat and / or coldset Webs in one or more simultaneously producible products as desired are placeable.

The advantages that can be achieved with the invention are, in particular, that a large product variability is achieved with at the same time low investment, operating and production costs.

By virtue of the fact that each of the machine lines arranged in parallel and formed by the subsections has its own folding unit and in that each machine line has a turning bar arrangement for the individual transfer of individual webs or partial webs printed between the machine lines with the subsections, it is possible to to supply the webs or partial webs printed in the subsections individually and independently of one another to any folding mechanism. Thus, if the page number of a first product to be produced does not fully utilize the capacity of a first subsection, the possibility arises to supply a web or sub-web printed by that first subsection to another folder for producing a second product which may be independent of the first. As a result, a high utilization of the printing units of the rotary printing machine is achieved. Another advantage of this arrangement is that in case of failure of a folding unit of a subsection production does not come to a standstill, but by the turning bar assembly which can be fed from the affected by the partial section partial printed sheets or partial webs a folder of other subsections. Preferably, at least one folding unit is equipped with one or more displaceable formers to process different widths of webs can.

The use of so-called Ribbondecks above the formers executed turning bar arrangements for the individual transfer of webs or partial webs between the machine lines allows for low height flexible placement of each sub-web of heatset webs in the finished product.

• Sehr kurze Bahnwege. Dadurch wird ein geringes Bahnbruchrisiko erreicht.
• Die gesamte Rotationsdruckmaschine weist kompakte Außenabmessungen auf, wodurch ein geringerer Raumbedarf verbunden mit geringeren Investitionskosten für die Produktionsräumlichkeiten entsteht. Außerdem wird weniger und einfacher ausführbares Equipment für den Betrieb der erfindungsgemäßen Rotationsdruckmaschine benötigt.
• Der Einzug von automatischen Rollenwechslern bis zu den Falztrichtern der Falzwerke erfolgt geradeaus, ist damit einfach ausführbar und birgt nur ein geringes Bahnbruchrisiko.
• Es ist keine Umlenkung durch Wendestangen erforderlich.
• Teilbahnen der Heatset-Bahnen können durch Verwendung so genannter Ribbondecks insbesondere bei Tabloidprodukten beliebig im fertigen Produkt platziert werden.

The rotary press is tailored for a separate tabloid production with different products produced in daily change. Advantages arise with very large product variability among others through:

• Very short railways. As a result, a low breakage risk is achieved.
• The entire rotary printing machine has compact outer dimensions, resulting in a smaller space requirement associated with lower investment costs for the production premises. In addition, less and easier executable equipment for the operation of the rotary printing machine according to the invention is needed.
• The collection of automatic reel splicers up to the formers of the folders is straightforward, so it is easy to carry out and involves only a small risk of breakage.
• There is no diversion by turning bars required.
• Partial webs of the heatset webs can be arbitrarily placed in the finished product by using so-called Ribbondecks especially tabloid products.

In summary, there are the following advantages:

• eine geringe Makulatur,
• ein geringes Bahnbruchrisiko,
• schnellere Produktionswechsel,
• eine minimale Personalausstattung und dadurch geringe Betriebs- und Produktionskosten.

By setting up the folders in line with the printing units, there are very short paths without path deflections for a major tabloid productions and thereby:

• a small waste,
• a slight breakage risk,
• faster production changes,
• minimal staffing and thus low operating and production costs.

The printing units of the subsections are preferably designed in the form of printing towers. Each printing tower preferably has eight to four printing units grouped printing units on, on both sides four-color printing on a web. Printing towers have a small footprint and thus reduce the investment costs for the production hall required for the installation of the rotary printing press.

The heatsets of the machine lines formed by the subsections can be designed as a hot air dryer or as a radiation dryer, preferably as an ultraviolet radiation dryer.

The rotary printing press preferably has three sub-sections in the form of three parallel machine lines, each sub-section each having at least two printing units, preferably designed as printing towers, each of which prints one or both sides of a web which can optionally be fed through the heatset. Preferably, the rotary printing press has a total of eight printing towers, a machine line with two, and two machine lines, each with three printing towers.

The rotary press may have variable width web processing means for producing variable page height and / or variable page width products. These variable width web processing means may include, for example, form cylinder and blanket cylinder printing units with continuous cylinder passages and continuous ink ducts. The printing units of the rotary printing press can be designed as conventional wet-offset printing units, or as dry off-set printing units, which has the advantage that the heatset printing units or printing units can be quickly switched to coldset operation as needed.

As part of the means for processing variable width webs, the middle subsection may have three, five, seven, etc. parallel machine lines Rotary printing machine, a double seaming, ie two Querfalzwerke, with a six transverse to the machine line slidable folding hoppers comprehensive Falsetrichteraufbau have.

In this case, the six formers can be arranged in two superposed Falztrichterebenen.

As part of the means for processing webs of variable width, the outer subsections can each comprise a folding unit with a three former extending transversely to the machine line folding hoppers.

• vier Seiten breite Produktion 15" und 16¾" hoher Tabloide ohne Wendung,
• fünf Seiten breite Produktionen mit 13½" hohen Tabloiden ohne Wendung,
• sechs Seiten breite Produktion als Broadsheet-Backup mit Wendung für die Bahnen der äußeren Maschinenlinien sowie zur Erzeugung der gewünschten Buchstruktur.

The use of three folding hoppers in the width allows either:

• four pages wide production 15 "and 16¾" high tabloids without twist,
• five-page productions with 13½ "high tabloids without twist,
• Six pages wide production as broadsheet backup with turn for the tracks of the outer machine lines as well as for the production of the desired book structure.

The main production of the rotary printing press preferably provides for the production of up to one-hundred sixty-page tabloid products. Preferably, the tabloid products can be produced with a variable page height and can optionally include heatset web-produced covers, backsides, interior pages such as panorama pages, and pages that can be placed anywhere in the finished product.

Another production of the rotary printing machine preferably provides for the production of up to eighty-page broadsheet products with up to six books on one of the three folding units, as a backup for a newspaper press in the broadsheet format provided, further rotary printing press. Thus, in addition to its great product variability, the rotary printing press is able to place heat and coldset webs that can be placed anywhere in a product as a back-up for a rotary printing machine Newspaper printing to be used in broadsheet format.

With the turning bar assemblies of the subsections are preferably all printed with the rotary printing press and dried by passing through a heatset heatset webs together on one of the folding units, the at least one remaining folding unit, the remaining coldset webs can be supplied for the separate production of pure heat and coldset products.

The turning bar arrangements of the individual subsections can have web-wide turning bars. The use of wide web turning bars for the outer line heatset webs allows for easy insertion of these heatset webs onto the folder or folder of the middle machine line for separate, pure heatset production.

It is important to emphasize that a list of rotary printing machine both as a substructure with below the printing units or printing towers, typically under a hall floor, arranged automatic reel splitter, as well as a so-called parterre machine with arranged in the machine lines of subsections on the hall floor automatic reel splitter possible is.
