Description

The invention relates to a processing module according to the preamble of claim 1 and a carrier unit according to the preamble of claim 7, which together form a printing press according to claim 11.

State of the art

Printing presses for printing on labels and folding cartons increasingly require a great deal of flexibility or variability in order to be able to carry out as many different types of printing jobs as possible, in particular by producing special optical effects through the printed image or the printed text. For the production of labels and folding cartons printing presses are particularly frequently used which process a narrow web of a printing material and have a number of connection platforms or interfaces, on each of which a functional unit or a process module can be detachably picked up for printing with a specific printing process. For example, one embodiment of such a printing press is in the document US 4,384,522 described. The individual functional units can work with mutually different printing methods.

From the documents DE 195 13 536 A1 and WO 95/29813 Multi-printing presses are known in series construction which permit the detachable receipt of a number of functional units or process modules on a number of interconnect platforms. The functional units may contain, among other things, printing units or parts of printing units in cassettes or essays which operate according to a letterpress method, a flexographic printing method, a screen printing method, an offset printing method, a gravure printing method or an inkjet printing method. In addition, functional units (processing units) are provided which allow mechanical processing steps on the printing material, for example a Embossing, a trimming (perforation, punching) or make a turn. Such printing machines, which can operate on a variety of different printing methods, are also referred to as combination printing machines or hybrid printing machines.

For many years now, printing presses and individual components used in them have been produced on a large scale from metallic materials, in particular from steels, aluminum or titanium. In addition to suitability based on some of their physical and technical properties, the traditional use of these materials is evidently due to, among others, the widespread availability of both qualitative skills and quantitative capacities to produce and adequately process metallic materials. In printing presses with modern printing technology usually get large castings made of metallic materials for the machine support structure used, which undergo their shape in technically complex and often costly processing steps. As a consequence of the use of metallic materials in modern printing technology, supporting technical measures are generally required to counter some of the particular undesirable physical properties of these materials, such as electrical conductivity, thermal expansion or mechanical vibration behavior, or consequences of these properties.

Both aforementioned aspects will be described in the DE 10 2006 042 884 A1 encountered. Disclosed is a printing press, in particular label printing machine or sheet-processing offset printing machine, the printing units are housed in a stone-made machine support structure. Different printing units can be used or exchanged and the printing press can be adapted to a particular job.

In order to be able to handle print jobs even more flexibly and to operate existing printing presses with higher utilization, increasingly greater flexibility is required in the design of the printing press.

task

Object of the present invention is therefore to provide a printing machine, the structure of which can be changed extremely flexible.

This object is achieved by the provision of a processing module according to claim 1 and a carrier unit according to claim 7, which together form a printing press according to claim 11.

In other words, carrier units and processing modules are in a defined relationship to each other and are particularly adapted to each other.

The carrier unit according to the invention serves for receiving and arbitrary positioning of processing modules for printing and print finishing for modular construction of a narrow web label printing machine. According to the invention, the support unit has a solid cuboid with at least three feet and at least one longitudinal guide, wherein the feet are attached to the underside of the cuboid and wherein the longitudinal guide is attached to the top of the cuboid and extends over the length of the cuboid. Such a carrier unit is characterized by a very simple structure, which allows a simple and cost-effective production of the carrier unit. It is particularly advantageous if the cuboid is made of natural stone, for example granite, or of artificial stone, for example concrete, mineral cast material or polymer casting. These materials are significantly less expensive than metal materials and have better properties in terms of vibration behavior, strength, availability and processability.

In a particularly advantageous and therefore preferred embodiment, the longitudinal guide is designed as a longitudinal guide rail. This can have a grid, such as a hole grid, have. Counter-elements of processing modules can intervene in the grid. The grid can thus be used to specify defined positions for the processing modules, and these can be set at defined intervals be positioned to each other on the carrier unit. If the longitudinal guide is executed without a grid, the processing modules can be freely positioned.

In an advantageous development of the carrier unit according to the invention, at least one of the feet has a leveling element for changing the height of the cuboid. As a result, unevenness of the base can be compensated and the cuboid be placed in a horizontal position.

In an advantageous embodiment, the carrier unit has coupling elements for connecting, i. Line up two carrier units. These can be aligned relative to one another via the coupling elements.

The invention also relates to a processing module for the printing and further processing of a web-shaped printing material for use on a carrier unit as described above and for the modular construction of a narrow web printing press. The processing module is used for transport and / or processing of the printing material. According to the invention, the processing module has a support structure, a transport cylinder and two deflection rollers, wherein the deflection rollers are arranged mirror-symmetrically to a vertical axis of symmetry through the axis of rotation of the transport cylinder. The mirror-symmetric structure allows advantageously to be able to freely choose the direction of the to be printed and processed web-shaped substrate.

In a particularly advantageous and therefore preferred embodiment of the machining module, the supporting structure has at least one longitudinal guide element mounted on its underside for positioning the machining module on a carrier unit, in particular as described above. In other words, the longitudinal guide of the carrier unit and the longitudinal guide element of the processing module represent the interface for connecting carrier unit and processing module with each other.

In an advantageous embodiment, the support structure is mirror-symmetrical to the vertical axis through the axis of rotation of the transport cylinder.

In a further development of the processing module according to the invention, the processing module may have interfaces for connection to an additional functional unit, this additional functional unit serving to carry out additional processing steps on the web-shaped printing substrate. The additional functional unit can be designed as a printing unit and form a printing unit together with the processing modules. The additional functional unit can also be designed as a stamping and / or embossing unit and together with the machining module form a stamping and / or stamping unit.

The invention also relates to a narrow web printing machine, comprising at least two carrier units as described above and at least three processing modules as described above, wherein the processing modules are positioned on the carrier units. Such a narrow web printing machine can advantageously be changed quickly and simply in terms of its construction and adapted to the requirements of a particular print job. Thus, on the one hand, the number of processing modules that can be positioned on the carrier units, not limited from the beginning. On the other hand, the processing modules can be moved variably in their position on the carrier units. Another advantage results from the fact that different web widths can be realized with the same carrier units: the processing units only extend beyond the carrier units with larger web widths.

In an advantageous development of the narrow-web printing machine according to the invention, in particular label printing machine, the at least one longitudinal guide of the respective carrier unit and the at least one longitudinal guide element of the respective processing module have mutually complementary profilings. These profiles represent the interface of carrier units and processing modules, and ensure that the processing modules can be quickly and easily positioned and fixed on the carrier units with simple steps.

The described invention and the described advantageous developments of the invention are also in any combination with each other advantageous developments of the invention.

With regard to further advantages and constructive and functional aspects of advantageous embodiments of the invention, reference is made to the dependent claims and the description of embodiments with reference to the accompanying drawings.

Corresponding elements and components are provided in the figures with the same reference numerals.

Fig. 1a shows a carrier unit 12, which is formed by a block 1, namely a solid cuboid. The massive cuboid 1 has on its upper surface two longitudinal guides 4 with breadboard. The block 1 is held by four feet, which are formed by profile beams 2 and adjustable leveling elements 3. By rotating the leveling elements 3, a height compensation is possible, and the block 1 can be aligned so horizontally. In Fig. 1b is the carrier unit 12 in a view and in Fig. 1c shown in a side view.

In the FIGS. 2a to c Different variants of the longitudinal guide 4 are shown. In Fig. 2a a longitudinal guide 4 is arranged as a raised element in the middle of the block 1. In the variant according to Fig. 2b the longitudinal guide 4 is designed as a centrally inserted into the surface of the block 1 groove. As shown by Fig. 2c two longitudinal guides 4 in the form of mutually parallel rails on the surface of the block 1 are arranged.

The FIGS. 3a and 3b represent alternative variants for the arrangement of the leveling elements 3 on the underside of the block 1. While according to Fig. 3a three leveling elements are arranged on the underside of the block 1, are according to Fig. 3b four leveling elements 3 arranged on the underside of the block 1. The three leveling elements 3 span a triangle or the four leveling elements 3 form a rectangle. Of the three leveling elements 3, at least one should be adjustable, while four of the four leveling elements 4 are preferably all adjustable.

In Fig. 4 a process carrier system with two carrier units 12 is shown, which are arranged in series. The two support units 12 are connected by a coupling element 13 not shown in detail. The coupling element 13 can also continue to serve to align the carrier units 12 to a common longitudinal axis. While in Fig. 4 By way of example, only two carrier units 12 are coupled to one another, it is also possible to connect an arbitrarily larger number of carrier units 12 to one another. The number of required carrier units 12 is determined by the space required for positioning of process modules on the carrier units 12.

Fig. 5a shows a processing module 21 in its most general embodiment. The processing module 21 has a support structure 25, a transport cylinder 22 and two pulleys 23. The processing module 21 is constructed mirror-symmetrically to a symmetry axis S, wherein the axis of symmetry is a vertical axis through the axis of rotation of the transport cylinder 22.

In Fig. 5b the application of the processing module 21 is shown on carrier units 12. Due to its reduced design to the essential elements, the processing module 21 can be used in different positions for different tasks.

FIGS. 6a to 6c show alternative embodiments of the guide member 24. As shown by Fig. 6a the underside of the support structure 25 of the machining module 21 has been provided with a groove. This centrally disposed groove 24 is complementary to the in Fig. 2a shown rail 4 of the carrier unit 12th

In the variant of Fig. 6b was mounted on the underside of the processing module 21 as a guide member 24 a rail. Alternatively to a continuous rail and at least two separate noses could be used. The rail or the lugs 24 are complementary to the groove 4 of the support unit 12, as in Fig. 2b shown executed.

In the variant of Fig. 6c the machining module 21 was provided on its underside with two grooves as guide elements 24. These grooves 24 provide complementary elements to the two rails 4 of the carrier unit 12 - as in FIG Fig. 2c The three variants shown are to be regarded as exemplary - all have in common: the longitudinal guides 4 of the carrier unit 12 and the guide elements 24 of the processing modules 21 are formed complementary to each other so that they can interlock and processing modules 21 simply with carrier units 12th can be connected.

While the transport cylinder 22 of the processing module 21 is used in the most general embodiment exclusively for the transport of the web-shaped printing material, the transport cylinder 22 in the printing modules 7 and 8 forms the counter-pressure cylinder and the punching module 10, the counter-punching cylinder. The in the FIGS. 7b or c and d or e illustrated variants, according to which a pressure roller or a UV drying module can be arranged left or right, are used depending on the direction of the web-shaped substrate.

The combination of the carrier units 12 with processing modules 21 and additional functional units to a narrow-web label printing machine 100 goes out of the FIGS. 8a to 8d out. In all three examples four carrier units 12 were coupled in series and different process modules were positioned on the carrier units 12 according to the requirements of the print job. In the example of Fig. 8a For example, a web transport module 5, a gravure printing module 6, two flexographic printing modules 7, a digital printing module 9, a screen printing module 8 and a stamping module 10 were used. According to the example of Fig. 8b For example, a web transport module 5, a stamping module 10, a gravure printing module 6, a flexographic printing module 7, a screen printing module 8, a further flexographic printing module 7 and a digital printing module were used. In the example of Fig. 8c the first processing module 21 forms a web transport module 5, followed by a screen printing module 8, five flexographic printing modules 7 and an embossing module 11, before another processing module 21, which again forms a web transport module 5, forms the last process module. A carrier unit 12 can receive one, two, three or even more processing modules 21 with additional functional units. The latter can - as described above - on the basis of a grid in defined positions or in use a guide without grid freely on the support units 12 are positioned. In the example of Fig. 8d In addition to a flexographic printing module 7 and a screen printing module 8, four offset printing modules 14 were also used.
