Description

The present invention relates to a support frame for one Web-fed rotary printing press comprising at least one printing unit.

In known press configurations the printing units of a printing tower are stacked on top of each other or even the elements of Printing units, namely the cylinder elements and the Dyeing and dampening units, each individually juxtaposed and juxtaposed. An example of the first of these two Configurations are known from DE 42 19 705 A1. In In both cases, the juxtaposed units each be trained in itself and carry the attached units with you. you are therefore provide in accordance with stable design. The design effort of such a support structure is further increased by the fact that the cylinder, color and Dampening elements themselves take a supporting function and to dimension accordingly stronger are as they require their actual task would.

A support frame for a web-fed rotary printing press for receiving at least one printing unit, by a cylinder element with several Cylinders and the cylinder element associated color and Dampening is formed, is known from DE 29 24 591 A1 known. This document is particularly relevant a substructure for a web-fed rotary printing press. The substructure is in an externally prefabricated Metal framework molded with support elements on which the paper holder, paper drive, paper feed and Paper changing devices are attached. The Printing units of this printing press are on the Substructure on. This is intended to pull a false ceiling be avoided on pillars would have to rest.

The present invention has the object made a support frame as a support structure for a web-fed rotary printing machine so to create that in it the individual printing machine elements modular can be built with the least possible Effort for the required stability and optimal Accessibility for the operation and maintenance of the Printing machine elements. The printing press should by the invention cheaper and cheaper to operate become.

This task is accomplished by the subject of claim 1.

The subclaims are advantageous, not smooth self-evident embodiments of the subject directed by claim 1

In a printing unit or a printing tower a web-fed rotary printing press with at least two superposed printing units, each Cylinder elements with multiple cylinders and these Zylinderelmenten associated with inking and dampening have, according to the invention, the cylinder elements and the inking and dampening units in a supporting structure held, as a support frame already in itself yourself or at least in rigid connection with supporting the cylinder elements is stable.

This will be a breakdown of the Pressure units or even the individual cylinder elements and the inking and dampening avoided. These units do not need intrinsically stable in themselves to be. In particular, the cylinder elements must and inking and dampening units themselves none carrying functions in the structure of the printing press can take over and therefore easier and cheaper than conventional construction be built. While in the conventional Construction made the bearing parts themselves in register must be, so that the cylinders and rollers in the Tragkonstruküon be involved and a supporting one Function to take over, it requires at the Support structure according to the invention no exact fit Processing. Supporting construction parts can therefore particularly cost-saving made of reinforced concrete or similarly manufactured low-cost building materials. The one in the production of a suitable hall floor to be driven effort when using the reduced support structure according to the invention. Further can the support structure already independent of the complex machine parts set up at the destination become. After their formation, the Cylinder elements, inking and dampening units, the folder and other machine parts easily and very quickly Install in the existing support structure. By the support structure according to the invention, in particular the intrinsically stable support structure, it will possible, the printing press largely modular from comparatively easily replaceable units build. The modular units do not build anymore on top of each other, but they can at the Supporting structure are supported, for example by a fixed adjustable connection, by hanging, or they may be movably held to it. Finally, the invention allows the printing press with the least possible additional effort with Working platforms for the operating and maintenance personnel equip. The operation of the printing press used work platforms can also already at the Installation of the machine, especially during installation the machine parts in the supporting structure in the supporting structure integrated or merely provided become.

The support structure according to the invention allows an improvement in a particularly simple way the accessibility of machine parts by the inking units or parts thereof as modular units are trained who are facing from their working position the respective cylinder elements movable the supporting structure and / or cylinder elements are held. Although the combination of a supporting structure according to the invention with the mentioned Movability of inking units, dampening units and possibly other machine parts special Advantages, also brings the mobility alone already advantages in terms of space requirements and for the maintenance of the machine.

The mobility of inking units par excellence is known from DE-AS 1 169 959. There is one as Series machine trained multicolour sheet-fed rotary printing machine disclosed. Their pressure unit is by two, a printing cylinder associated, about one above the other arranged mold or plate cylinder and this in turn assigned inking formed. The two inking units are in one common Frame on inclined tracks in the transverse direction to the Longitudinal axes of the form or plate cylinders movable.

One in the transverse direction to the cylinder longitudinal axes Movable unit of printing cylinders is out of the EP 0 315 917 A2.

In contrast, according to the invention to inking units combined inking units movable in the direction of the cylinder longitudinal axes arranged on the supporting structure

Since the movable units in the direction of Rotation axes of the cylinder can be moved compared to the known sliding or pivoting mechanisms a reduction across the axes of rotation the rollers measured length of the Printing machine can be achieved. This advantage comes especially with the big, trained as row machines Rotary printing machines, the 8, 16 or have more consecutively arranged printing towers can, to bear. Compared to the conventional ones Towers that are not movable units can own the cylinder elements and inking units be arranged closer to each other, because on the otherwise for access to the cylinder elements and inking units necessary maintenance tunnel be waived can. In the working position of the cylinders and the inking unit therefore no longer needs accessibility to be respected, so that the inking units each in itself and also opposite to the other inking units and compared to the cylinder elements space-saving can be built and arranged. In the extended position are both the color and Dampening units as well as the printing cylinder elements optimally accessible. Furthermore, the replacement can of machine elements in case of major maintenance or repair almost without interruption of production be made. It can also be the Increased versatility of such printing units, for different quality requirements the printed products have different color works alternatively used and in their respective working position can be driven. In the same press can thus easily different Inking units, e.g. Short inking units with different inking processes for different printing qualities or Printing units with different printing methods such as e.g. Flexo or gravure used or ever exchanged with one another as required and if necessary be combined with each other.

Also can be conventional blanket cylinder against new blanket cylinders with Endlosgummitüchern for using a computer to press system replace later.

It is particularly advantageous in the movable Units each one cooperating with the inking unit Dampening unit as the inking unit partly or in Integrated whole. Thus, not only is the respectively extended Inking unit or dampening unit for maintenance work easily accessible, but it can also be the according to uncovered part of one or more Form or plate cylinders, blanket cylinder and, if necessary, a central cylinder existing cylinder element easily accessible for maintenance be made. Especially preferred is a whole Inking unit with a whole dampening unit to such a movable unit summarized. Either the cylinder elements as well as the inking and dampening units are freely accessible after their extension. The Changeover times when changing color and dampening types are the shortest and the constructive effort is because of the small fragmentation on the least. In this summary of color and Dampening plants are also the most extensive Reductions in the overall height and the Total length of the press achieved

Advantageously, there is between the cylinder elements and the movable units except the bracket to the support structure no mechanical Connection. The movable units are each equipped with a separate drive. In principle, however, would be a coupling of the movable Units in a drive system for the Entire printing unit possible, but with how before an additional auxiliary unit for driving the Rolling the movable unit in extended Condition would be necessary. In addition to the own drive The movable unit also has one for the implementation Maintenance unit necessary control unit on.

The supply of the movable unit, i. the supply of the drive and the control device, Can be a tow cable or a first in the extended Condition produced plug connection done.

In the figures 1 and 2 are printing towers 1 with in each case two printing units arranged one above the other 5, of which Figure 3 enlarges a single again shows, in lateral cross-section and in one Front view shown. A web-fed rotary printing machine is by at least one printing unit. 5 or several arranged one behind the other Towers 1, at least one folder 3 and at least one printing material roll stand 4 educated.

The printing units 5 are in the Austuhrungsbeispiel according to the figures 1 to 3 in each case in a modular manner a cylinder element 6 and four associated, movable Units 10 constructed. The cylinder element 6 is in the form of a satellite printing unit with a central cylinder 7, four blanket cylinders 8 and four the Blanket cylinders 8 assigned form or plate cylinders 9 trained. The cylinder element 6 is at four stationary columns 30, which are for the printing units 5 lateral column pairs 30 form, rigidly fixed while the units 10 are attached to the columns 30 Running rails 19 in the direction of the axes of rotation 21 of the cylinders 7, 8, 9 are movable. The movable ones Units 10 are each by an inking unit 11 and a dampening unit 15 formed. The inking rollers 12 and the dampening form rollers 16 are of the Shaped cylinders 9 swing away.

The printing units 5 are respectively to the whose two sides arranged column pairs 30th supported, together with connecting cross members 50, 150, 151, 152 the essential part of a supporting structure 2 form. The printing units 5 are on this way from the lateral column pairs 30 and an upper and a lower cross member 50, respectively framed. Each of the traveling units 10 can individually straight in the direction of the axes of rotation 21 of Cylinders 7, 8 and 9 between a working and a Maintenance position to be postponed. To this Purpose run the units 10 with rollers 20 in the rails 19. There are, however, others as well Traveling mechanisms conceivable. The two each about a cylinder element 6 arranged units 10th be hanging, and each under the cylinder element 6 arranged units 10 are supported over the cross members 50 from the pillars 30 carried.

The cylinder elements arranged one above the other 6 are on one right and one on the left standing column pair 30, for example, by appropriate Aligning and connecting elements supported. The supporting structure 2 of the embodiment is sufficiently inherent stiffness to both the cylinder elements as well as the inking and dampening equipment. So also the cylinder elements 6 basically be modular exchangeable. The cylinder elements 6 can but also with sufficiently stable design and stabilizing according to solid bond with the columns 30 and integrally integrated into the supporting structure 2 become. Corresponding deductions could be made in this case in the carrying capacity of the columns 30 and the Cross members 50, 150, 151, 152 are made.

Figure 4, in the equivalent components with the same Reference signs are provided, two left shows Pressure units 5 in a conventionally constructed Printing tower 1 and on the right in comparison to the printing units of the printing tower 1 of Figure 1, in addition to the inherently rigid supporting structure also the further feature the movable inking and dampening units 10, so that the maximum space savings is achieved. Clearly recognizable is the space required for a necessary in the conventional printing tower 1 Maintenance tunnel 60, the non-moving color and Dampening units 11, 15 must be left to and to carry out repair work. As a result of the movable in the direction of the cylinder longitudinal axes Color and dampening units 10 can in the right in Figure 4 printing tower 1 maintenance tunnel completely eliminated, because not only the extended color and Dampening units are freely accessible, but also the Cylinder elements 6 as needed by the method a color and dampening unit 10 completely exposed can be. This allows the printing units 5 flatter and narrower to be built. The Reduction of the pressure tower height is in the embodiment over the corresponding conventional Printing tower 1 on the left half of figure 4 about 15%.

Also decrease in the inventive Supporting structure the number of operating levels and the intermediate platforms clearly.

The support structure 2 is, as in Fig. 2 to can be seen, by further columns 32, in the longitudinal direction the cylinder 7, 8, 9 each next to a pair of columns 30 are arranged, developed. The Arrangement of the columns 32 is approximately mirror-symmetrical to that of the columns 30, with which they extended by Cross beams are connected. The can two left columns 32, the only proportionately the Dead weight of the supporting structure 2, which is from the Working position driven units 10, the maintenance staff and necessary for maintenance and repair Need to record equipment, weaker be executed as the columns 30. In the embodiment the pillars 32 still carry a working crane 23 to support the work.

In the lower left part of Figure 2 is an im disengaged state, i. in the maintenance position located unit 10 indicated in dashed lines. In this position, the combined to the unit 10 Parts of the inking and dampening unit 11 and 15 via a stationary connector 21 with Energy and possibly with data for a separate drive and, if necessary, a control unit for the rollers of the movable Unit 10 supplies. The lifting crane 23 can because of the lighter weight of the movable Unit 10 combined inking and dampening units or cylinder unit for a lower lifting load than this for the printing units of conventional printing machines necessary, be designed, which in turn Cost benefits entails.

FIG. 5 shows the printing tower 1 of FIG Top view in which the pairs of columns 30 laterally from the two arranged side by side, in the direction of Arrows A movable units 10 can be seen. Furthermore, one in the direction of arrow B across to Extension direction of the units 10 movable platform 35 indicated. Such work platforms 35 are again more clearly in Figure 6 together with several in the maintenance position moved out units 10th located. The working platforms 35 are each under and / or over the extended units 10 of Pressure units 5 along other diverse cross member guided movable. Free movability of working platforms is also possible if on the various carriers provided otherwise resting floors become.

Like the described embodiment makes clear, the benefits of the invention come quite especially when wearing the printing press by a series arrangement of several printing units 5 or printing towers 1, each with several superimposed arranged printing units 5 in turn, respectively several inking and / or dampening units 11 and 15 is formed. In this case, the biggest cost savings and the biggest room savings in terms of to the press length and height expect. In the mobility of the invention Moreover, the inking and dampening units do not require any space required, not even with fixed Color and dampening would occur, as well as their Rollers and / or cylinders when changing direction their axes of rotation from the printing press should be drawn. In contrast, need the known printing machines with otherwise movable Ink and dampening always additional Space that would not arise with a fixed arrangement. To save space further contributes to the concept of the extended fab and dampening moved Working platforms, without concessions to the To require accessibility. In the embodiment with Four inking and dampening units per printing unit are each Dampening and dampening unit in its maintenance position of three pages freely accessible. The support structure according to the invention enables this high degree of modularity, including the traversability of the color and Dampening units, what a simple installation the printing press and later necessary changes benefits from machine parts.

FIG. 6 shows the printing tower of FIG. 5 in FIG Front view, in each case a unit 10 a lower and an upper pressure unit in the direction of Rotation axis 21 of the cylinder 7, 8, 9 in the maintenance position is extended. Furthermore, it can be seen that ever a working platform 35 for a lower and an upper Pressure unit 5 in the direction of arrow B transverse to the extension direction the units 10 can be moved. The units are 10 with the work platforms drive under or drive over. It can also be seen that for the operation of the units 10 no additional Zwichenplattformen according to the conventional Construction according to Figure 4 are necessary.

FIG. 7 shows a section from the front view of Figure 3, in which a cylinder element 6 by means dome-shaped alignment and Connecting elements 17 on the columns 30 solvable is attached. The alignment of the cylindrical elements 6 takes place in the vertical direction between the columns 30th and in a horizontal direction between the different ones Cross members (50, 150, 151, 152) by means of the alignment and connecting elements 17, 18. The detachable Arrangement of the alignment and connection elements (17, 18) can at precisely machined places the Columns (30) take place.

The alignment of the units 10 takes place by means of the alignment of the rails 19, according to Figure 3, those with the same alignment and connection elements 17, 18, not shown, are attached like the cylinder elements 6th

FIG. 8 shows a further exemplary embodiment the inventive support structure. One in front view illustrated web-fed rotary printing press, consists of at least one printing unit 5, a Folder 3 and a Bedruckstofrollstander 4. The folder is also in different Cylinder elements, not shown, divided, the like are formed so that they correspond to the cylinder elements 6 align with the columns 30 and detachable let attach. The printing material roll stands 4 be with the same way on the pillars 30 attached. When using the inventive Supporting frame supported on the machine foundation It can be considered as a significant cost saving the elaborate custom machine table base be waived. The folder and roller stand element can also be in the direction of the axis of rotation 21 between a working and maintenance position be moved.
