Abstract

Two web fed rotary printing presses (11,12) positioned close to each other at minimum axial distance in between, each have roll exchange machines (23) arranged in row (13,14).

Description

The invention relates to an arrangement of at least two web-fed rotary printing machines according to the preamble of claim 1.

Web-fed rotary printing presses are composed of several units, namely a roll changer unit, a printing unit, a turning bar unit and a folding unit. The reel changer unit comprises a plurality of reelstands and the printing unit comprises a plurality of printing towers, wherein a plurality of printing units are arranged within each printing towers. The turning bar unit comprises a plurality of turning bars and the folding unit has at least one folding structure and at least one folding unit. In printing shops, several such web-fed rotary printing presses are typically positioned in a workshop. In this case, according to the state of the art, the available building volume of the workshop is not optimally utilized, so that here losses of effectiveness occur. This is partly due to the fact that the web-fed rotary printing presses are not optimized in terms of their installation space. Rather, it is customary to adapt the design or execution of a workshop to the arranged in the same web-fed rotary printing press, resulting in a complex or sophisticated building design. This results in each customer or in each building a different and individual arrangement of the web-fed rotary printing press, which ultimately mobility and flexibility for the customer is limited. Thus, it is usually not possible for a customer according to the state of the art to move a printing press arrangement identically from one work shop to another work shop. Rather, either relocation work on the web-fed rotary printing presses or conversion work on the factory halls must be carried out when moving. Due to the fact that according to the state of the art the printing machine arrangements always deviate from one another, none arise either Repeat effects in the operation of the printing presses, so that operators must always be trained on a specific press assembly. This also ultimately results in loss of effectiveness.

On this basis, the present invention is based on the problem to provide a novel arrangement of at least two web-fed rotary printing presses.

This problem is solved by an arrangement of at least two web-fed rotary printing machines according to claim 1. According to the invention, the roller printing presses are arranged on the one hand with a minimum axial distance to each other for space minimization, on the other hand, at least two of the roll changer of each roll changer unit are positioned one above the other.

By means of the printing machine arrangement according to the invention, the dimension of the same in all three spatial directions and thus the space required by the same space is minimized. The building volume of a workshop can be optimally utilized. Furthermore, the mobility is significantly improved for a customer, as with the printing press assembly according to the invention a move to another workshop is much easier to implement than in the prior art. On a sophisticated or tailored to a specific printing machine assembly building design can be dispensed with. With the printing machine arrangement according to the invention, printing centers can be set up with recurring printing press arrangements, so that ultimately also repetitive effects occur in the operation. After a move then the operator does not have to be trained again on a special printing press arrangement. Operating personnel can be flexibly used in different printing centers, which make use of the printing press arrangement according to the invention, without any need for retraining.

Preferably, the axial spacing of the web-fed rotary printing presses is adapted to the production of a common printed product such that to ensure a section flexibility of the printed product and / or a page flexibility of the sections of the printed product printed in the printing unit of a first web-fed rotary printing press and optionally pre-folded substrate entirely or partially an adjacent second Web-fed rotary printing machine can be fed.

According to an advantageous development of the present invention, a printed, non-folded and therefore web-shaped printing material can be fed completely or partially from the turning bar unit of the first web-fed rotary printing press of the turning bar unit of the adjacent, second web-fed rotary printing press to ensure side flexibility of the sections of the printed product. To ensure a section flexibility of the printed product is a printed and pre-folded in a folding structure of the folding unit of a first web-fed rotary printing press and thus strand-shaped printing material a folding unit of the folding unit of an adjacent, second web-fed rotary printing machine fed.

Hereinafter, the present invention will be described in more detail with reference to FIGS. 1 to 8.

Fig. 1 to 6 show a first embodiment of a printing machine assembly 10 according to the invention, wherein Fig. 1 is a side view and Fig. 2 is a plan view of the printing machine assembly 10 according to the invention. In the exemplary embodiment shown, the printing press arrangement 10 comprises two web-fed rotary printing presses 11 and 12, wherein each of the two web-fed rotary printing presses 11 and 12 has a reel changer unit 13 or 14, a printing unit 15 or 16, a turning bar unit 17 or 18 and a folding unit 19 or 20 respectively , The above units are positioned one after the other in the axial direction of the respective web-fed rotary printing presses 11 and 12 respectively, the axial direction being visualized by the dashed lines 21 and 22.

It should be noted that an exemplary embodiment is described above. Of course, it is conceivable that the units 13 or 14, 15 or 16, 17 or 18 and 19 or 20 can also be outside the assembly 10 in the axial direction, so z.Bsp. Reel changer unit 13 or 14 and / or folding unit 19 and 20 at 90 ° to each other.

In the embodiment shown, each of the reel changer units 13 and 14 comprises a total of five reel splicers 23 and each of the printing units 15 and 16 comprises a total of four printing towers 24, wherein in each Druckwerkturm 24 more printing units are integrated. The turning bar units 17 and 18 have a plurality of turning bar 25 and the folding units 19 and 20 each have at least one folding structure 26 and at least one folding unit 27. FIG. 3 shows a detailed view of the roll changer units 13 and 14. FIG. 4 shows a detailed view 5 shows a detail view of the turning bar units 17 and 18, and FIG. 6 shows a detailed view of the printing units 15 and 16 of the two web-fed rotary printing presses 11 and 12.

In terms of the printing machine assembly 10 according to the invention, the two web-fed printing presses 11 and 12 are arranged on the one hand with a minimum axial distance to each other, and on the other hand, at least two of the roll changer 23 of each reel changer unit 13 and 14 are positioned one above the other. By maintaining a minimum axial distance between the adjacent web presses 11 and 12, the distance between the lines 21 and 22 and thus the extent of the printing machine assembly 10 according to the invention in the Y direction (see coordinate system of FIGS. 1 and 2) is minimized. By arranging at least two roll changers 23, the available space in the Z direction is optimally utilized and the installation space in the X direction is minimized. With the aid of the printing machine arrangement 10 according to the invention, it is therefore possible to realize a space optimization or space minimization. The distance between the lines 21 and 22 and thus the axial distance between the web-fed rotary printing machines 11 and 12 is preferably in a range of 4.5 m.

It should also be noted at this point that any arrangement of the units described above can also take place in two levels.

In the exemplary embodiment of FIGS. 1 to 6, two of the five reel changers 23 assigned to a web-fed rotary printing press 11 or 12 are positioned one above the other. It can be seen that the height in the area of the reel changer units 13 and 14 is adapted to the overall height of the remaining units of the web-fed rotary printing press 11 and 12, respectively. It should be noted at this point that, of course, a larger or smaller number of reel splitter 23 of the respective printing press 11 or 12 may be assigned.

In the embodiment of Figs. 1 to 6, the two web-fed rotary printing presses 11 and 12 are aligned parallel to each other, that the printing towers 24 of the printing units 15 and 16 of the two immediately adjacent web-fed rotary printing presses 11 and 12 adjoin each other with their drive sides 28. FIG. 2 shows the drives 29 of the printing tower towers 24 in the area of the drive sides 28. Operating pages 30, on the other hand, face away from one another, so that a circulating operating space is thereby created for the printing press arrangement 10 of FIG. 2.

It should be noted at this point that the immediately adjacent web-fed rotary printing presses 11 and 12 in the area of the printing units 15 and 16 can, of course, also be oriented with a different orientation to one another. Thus, Fig. 7 shows a printing machine assembly 10 a, which differs from the printing machine assembly 10 of FIG. 2 only in that the two web-fed rotary printing presses 11 and 12 are aligned parallel to each other, that the operating sides 30 of the printing towers 24 of the printing units 15 and 16 of the two Web-fed rotary printing presses 11 and 12 face each other. As a result, a common operating space 31 is created between the two web-fed rotary printing presses 11 and 12. Accordingly, in the embodiment of FIG. 7, the drive sides 28 of the printing tower towers 24 of the two printing units 15 and 16 face away from each other. However, since the two printing machine arrangements 10 and 10a with respect to the remaining details do not differ, same reference numerals are used here to avoid unnecessary repetition for the same modules.

Although not shown in the figures, it is also possible that the two web-fed rotary presses 11 and 12 are aligned with each other so that the drive side of the printing towers of the printing unit of a first web-fed rotary printing press is opposed to an operating side of the printing towers of the printing unit of a second web-fed rotary printing press. However, the arrangements of FIGS. 2 and 7 are preferred.

For the purposes of the present invention, it is further proposed to coordinate the axial spacing of the web-fed rotary printing presses 11 and 12 of the printing machine arrangements 10 and 10a according to the invention to produce a common printed product such that to ensure a section flexibility of the printed product and / or to ensure side flexibility of the sections Printed product a in the printing unit 15 or 16 of a first web-fed printing press 11 and 12 printed and optionally pre-folded substrate wholly or partially an adjacent second web-fed rotary printing press 12 and 11 can be fed. This makes it possible to branch off printed pages and / or sections from a web-fed rotary printing press and feed them to the adjacent web-fed rotary printing press. As a result, the flexibility of printed products to be produced can be significantly increased.

Thus, in the embodiments shown, for example, to ensure side flexibility of the sections of the printed product to be produced, a printed, unfolded and therefore web-shaped printing material can be wholly or partly fed from the turning bar unit 18 of the web-fed rotary printing press 22 to the turning bar unit 17 of the adjacent web-fed rotary printing press 11. For this purpose, the printed and web-shaped printing material is deflected by 90 ° on a turning bar 25 of the turning bar unit 18 of the web-fed rotary printing machine 12 and in this deflection of the turning bar unit 17 of the adjacent web-fed rotary printing machine 11 and deflected in the region of this turning bar unit 17 on another turning bar 25 again by 90 °, so that the branched substrate then runs back in the direction of the axial direction of the corresponding printing press. Accordingly, the printed pages printed on the web-fed rotary printing press 12 can be supplied in whole or in part to the adjacent web-fed rotary printing press 11 in order to make the page number of the sections produced there variable.

It is also within the meaning of the present invention, to ensure a section flexibility of a printed product to be printed and in a folding structure 26 of the folding unit 19 and 20 of a first web-fed printing press 11 and 12 pre-folded and therefore strand-shaped printing material a folding unit 27 of the folding unit 20 and 19 of the adjacent web-fed rotary printing press 12 and 11 supply. Thus, for example, in the folding unit 26 of the folding unit 20 of the web-fed rotary printing machine 12 vorgefalzter, strand-shaped printing material after leaving the corresponding folding structure 26 the folding unit 27 of the folding unit 19 of the adjacent web-fed rotary printing press 11 are supplied. In the embodiment of FIG. 4, in the region of the folding unit 19 of the web-fed rotary printing press 11, two folding structures 26 are positioned one above the other, each with two formers 32, whereas in the area of the folding unit 20 of the web-fed rotary printing press 12, only one folding structure 26 with two formers 32 is present. 4, shown in broken lines in the region of the folding unit 20, shows that a further folding structure 26 can also be arranged in the region of the folding unit 20.

The printing machine arrangement 10 or 10a according to the invention thus permits the exchange of printed pages or sections between adjacent web-fed rotary printing presses and thus increases the flexibility in the production of a printed product.

The web-fed rotary printing presses of the printing machine arrangements 10 and 10a according to the invention to be juxtaposed can be designed to be either identical or different. Differently formed web-fed rotary printing presses differ in particular with regard to the number of print pages which can be printed on the web-fed rotary printing presses. It is thus possible, for example, to position web presses within printing press arrangements 10 and 10a according to the invention, the printing units of printing group towers 24 of the web-fed rotary printing presses being designed differently such that a different number of printed pages can be printed in the circumferential direction and / or in the longitudinal direction of the corresponding printing cylinder 33 , For example, it is conceivable that on the printing cylinders 33 of the printing unit 15 of the web-fed rotary printing machine 11 in the longitudinal or axial direction of the printing cylinder 33 four printed pages and in the circumferential direction one print page is printable on the printing cylinders 33 of the printing unit 16 of the web-fed rotary printing press 12 in the longitudinal direction two Print sides next to each other and in the circumferential direction in each case one printed page can be printed one behind the other. The number of print pages that can be printed in the circumferential direction and longitudinal direction on the web-fed rotary printing presses can therefore vary or be the same between the individual web-fed rotary presses.
