[0014] The problem underlying the present invention is to provide a sheet processing machine with a cooling roller and an inspection device, as well as a sheet printing machine with a simultaneous double printing unit and a curing device.

[0015] This problem is solved according to the invention by the features of claim 1 and claim 2 22 This is solved by the following features:

[0016] The sheet processing machine is assigned a transport path provided for transporting sheets. The sheet processing machine has at least one coating device arranged along the transport path provided for transporting sheets, the coating device having at least one coating station for applying a material to the sheet. The sheet processing machine is preferably configured as a sheet printing machine. Preferably, a curing device is arranged downstream of the at least one coating station along the transport path provided for transporting sheets, and more preferably, the curing device has at least one UV radiation source, and more preferably, the at least one UV radiation source is configured as an LED-UV radiation source. Preferably, at least one cooling device is assigned to the curing device, the cooling device has at least one cooling element, and more preferably, the at least one cooling element has a pipe system for transporting a cooling liquid and through which the cooling liquid can flow. Preferably, the at least one cooling element is configured as a rotatable cooling cylinder. Preferably, at least one cooling device having at least one cooling element is arranged downstream of at least one coating station along the transport path provided for transporting the sheet, and more preferably, the at least one cooling element is configured as a cooling cylinder. By arranging the cooling device, the substrate is cooled rapidly after curing. This protects the substrate and allows it to be inspected and / or further processed more quickly. For example, deformation of the substrate during curing is reduced or avoided.

[0017] Preferably, at least one curing section of the transport path provided for transporting the sheet is defined by at least one active area of ​​the curing device. Preferably, the cooling section of the transport path provided for transporting the sheet is defined by at least one active area of ​​at least one cooling element. Preferably, each cooling section is located downstream of each curing section. By spatially separating the curing section and the cooling section, the first cooling stage can be performed passively, that is, by dissipating heat into the surrounding air. In this first stage, the temperature difference between the substrate and the surroundings is greatest, making passive cooling the most effective. After the first cooling stage, cooling by at least one cooling element can be introduced particularly efficiently. Furthermore, contact of the at least one cooling element with the applied material that has not yet been cured is avoided. This avoids contamination of the at least one cooling element.

[0018] Preferably, the cooling cylinder has at least one gripper system for gripping the sheet, which allows a particularly secure transport of sheet-like substrates.

[0019] Preferably, the at least one coating device has at least one plate cylinder, which is particularly designed to support at least one printing plate, and the effective circumference of the at least one cooling cylinder corresponds to an integral multiple of the effective circumference of the at least one plate cylinder. A circumference of at least double the effective circumference defines a particularly large section of the transport path provided for transporting the sheet through the cooling cylinder, thus enlarging the working area of ​​the cooling cylinder. This allows for particularly effective cooling and allows for high transport speeds and therefore high printing speeds.

[0020] Preferably, a curing device is disposed downstream of at least one coating station and upstream of at least one cooling cylinder along the conveying path for conveying the sheet. Preferably, the curing device has at least one UV radiation source and / or at least one LED-UV radiation source. Such a curing device can be used with low energy consumption.

[0021] Preferably, the curing device has at least one first curing device, which has multiple LED-UV radiation sources, and these LED-UV radiation sources are arranged in a manner that they are oriented laterally toward different points on the transport path provided for transporting the substrate. Preferably, the curing device has at least one first curing device, and multiple LED-UV radiation sources of the at least one first curing device are arranged one after the other in the transport direction and / or along the transport path provided for transporting the sheet. This allows for an operation that is tailored to each print job and therefore energy-saving and material-friendly.

[0022] Preferably, the curing device has at least one second curing device, and the transport path provided for transporting the sheets extends between the first and second curing devices, thereby enabling optimized curing, especially when printing on both sides.

[0023] Preferably, the sheet processing machine has a hardening and inspection module, more preferably the hardening device, at least one cooling element configured as a cooling cylinder, and at least one inspection device, and / or the hardening and inspection module has a separate machine structure. This allows, in particular, simple retrofitting to existing installations. Furthermore, a corresponding design ensures particularly good accessibility to the individual components.

[0024] Preferably, the sheet processing machine has at least one inspection device, which is oriented toward a region of the transport path provided for transporting the sheet, located downstream of the at least one cooling element. Preferably, at least one first inspection carrier, preferably an inspection carrier configured as an inspection transport cylinder, is arranged downstream of the at least one cooling element along the transport path provided for transporting the sheet, and at least one sensor device of the first inspection device is oriented toward the inspection carrier. Cooling the substrate before its inspection ensures that the printed product is inspected in a state closest to the desired final state, thus avoiding undesirable temperature-related uncertainties in the inspection. For example, the spectrum of the radiation emitted by the substrate is not negatively affected by superposition with corresponding thermal radiation. This is particularly advantageous for inspections in the infrared range. In particular, if curing and cooling are first performed and then inspection is performed, in addition to the advantages associated with the inspection, it also ensures that the inspection carrier is not contaminated by the applied material, such as printing ink or varnish. Thus, print quality can be improved as unwanted back transfer is avoided, and inconvenient frequent shutdowns of the converting machinery for cleaning and / or maintenance work are avoided.

[0025] Preferably, the at least one inspection device comprises a first inspection device, in particular for inspecting the first side of the sheet, and more preferably, an additional second inspection device, in particular for inspecting the second side of the sheet. Preferably, a transport path provided for transporting the sheet extends between the first inspection device and the second inspection device. Preferably, a second inspection carrier, in particular formed as a second inspection transport cylinder, is assigned to the second inspection device, and at least one sensor device of the second inspection device is arranged and oriented towards the second inspection carrier. This allows for simple inspection of both sides of the substrate.

[0026] The first inspection device preferably comprises at least one sensor device for detecting electromagnetic radiation in the visible range of the spectrum. The first inspection device preferably comprises at least one sensor device for detecting electromagnetic radiation in a first section of the infrared range of the spectrum, whereby for example security features of securities can be inspected for their correct manufacture.

[0027] Preferably, the first test carrier or test transport cylinder has at least one gripper system for gripping the sheet and / or is configured as a suction transport cylinder, each of which increases the accuracy of the positioning and transport of the substrate, in particular the sheet-like substrate, on the corresponding test carrier or test transport cylinder.

[0028] Preferably, the sheet processing machine has an upstream-arranged sheet transport means, in particular configured as a first chain transport system or preferably a chain gripper system, which further preferably has at least one rear chain deflection shaft, and a first transfer point, in particular in the region of the rear chain deflection shaft of the first chain transport system, for transferring the sheet from the upstream-arranged sheet transport means to a cooling element, preferably configured as a cooling cylinder. In this case, for example, the hardening section can be arranged in a region of the chain transport system that allows for substantially contactless transport and thus improved passive cooling without heating of the components. Accordingly, for example, the transport cylinder does not need to be excessively heated and / or excessively cooled.

[0029] Preferably, the sheet processing machine has, in particular, a second transfer point for transferring the sheet from the cooling element, preferably configured as a cooling cylinder, to the first inspection carrier or to the inspection transport cylinder. By arranging these components directly one after the other along the transport path, it is possible to save on construction space and / or transfer points.

[0030] The sheet processing machine is preferably configured as a security sheet printing machine. The sheet processing machine preferably has a multiple pile delivery. The sheet processing machine preferably has at least one Simurtan printing unit and / or at least one Simurtan double printing unit. In this case, the at least one Simurtan printing unit and / or the at least one Simurtan double printing unit constitute, for example, at least one coating device. The Simurtan printing unit allows printing to be achieved with particularly high registration quality. The Simurtan double printing unit also allows printing to be achieved with particularly high register quality. Gentle material handling, especially in a dried and cooled state, and appropriate inspection further allow an overall particularly high product quality to be achieved.

[0031] The cooling cylinder preferably has at least one cylinder body and two cylinder pins arranged at its end, with the cylinder body being assigned to the cylinder axis. The cooling cylinder preferably has a duct system configured to conduct a temperature-regulating medium. The cylinder body preferably has at least one base body, which preferably consists of at least 50% aluminum. This allows for particularly high thermal conductivity and simultaneously a low moment of inertia and thus high acceleration. The outer surface of the cylinder body preferably has at least one conveying area configured as a support surface for the sheet-shaped substrate. The outer surface of the cylinder body preferably has at least one cylinder groove, in which at least one holding means with a gripper system for holding the sheet-shaped substrate is arranged. The base body preferably has a plurality of flow channels formed as holes, which run parallel to the cylinder axis and are configured as components of the duct system. This allows for a particularly simple construction of the cooling cylinder. Preferably, the substrate has a layer formed on its outer surface by anodization.

[0032] The base body is preferably formed as a substantially tubular base body, which also contributes to a simple construction. Preferably, the base body has an internal cavity that extends parallel to the cylinder axis over the entire body, and the dimension of the cavity oriented perpendicular to the cylinder axis is at least 50% of the largest outer diameter of the base body. This allows for a lightweight yet stable construction. Preferably, the flow channels, formed as holes, extend parallel to the cylinder axis over the entire body. Preferably, the cylinder body has at least two end pieces, each containing a channel section and fluidically connected to the flow channels of the base body.

[0033] Preferably, the cooling cylinder comprises at least one scanning means arranged to cooperate with a cam disc for controlling a gripper system of the at least one holding means.

The at least one substrate supply device 100 has, for example, a transport section configured as a belt table. For example, at least one receiving device, preferably configured as a pile plate, is arranged on the receiving device. In this case, stacks of printing substrates configured as sheet piles can be arranged for singulation. The receiving device is preferably connected to at least one transport means that ensures that the uppermost sheet of the sheet pile is positioned in a defined position in each case, even if the sheet pile is worn out. The substrate supply device 100 preferably has a sheet singulation mechanism and a sheet transport mechanism.

Each of said reference points is preferably located at a point and / or component that is associated with the conveying direction T. The conveying direction T therefore preferably extends along the provided conveying path for the substrates 02 and / or sheets 02, respectively.

[0041] The processing machine 01 preferably has at least one processing device 200 for processing a substrate 02. The substrate 02 is preferably formed as a sheet-like substrate 02. The at least one processing device 200 has at least one processing position 201. The at least one processing device 200 is formed, for example, as a coating device 200 and preferably has at least one processing position 201 formed as a coating position 201, in particular for applying a material to the sheet-like substrate 202. Preferably, the sheet processing machine 01 has at least one coating device 200 with at least one coating position 201 for applying a material to the sheet 02, arranged along a transport path provided for transporting the sheet 02. Preferably, the at least one processing device 200 is formed as a printing unit 200 and has at least one processing position 201 formed as a printing position 201. The applicator 200 is, for example, configured as a positively coupled applicator 200 and / or has at least one printing cylinder 202, for example configured as a plate cylinder 202.

[0042] In the following, a printing unit 200 having at least one printing cylinder 202 and at least one printing unit 203 will be described as an example of the application unit 200. The at least one printing cylinder 202 is preferably configured as at least one plate cylinder 202. Preferably, the printing unit 200 is configured as a multicolor printing unit 200. Preferably, at least one printing unit 200 is provided with a plurality of printing units 203 and, accordingly, a plurality of inking units in order to print different printing inks on the same substrate 02 in the same production run, for example, corresponding to the number of inking units. In one embodiment, printing units 203 operating according to different printing principles are arranged in the same printing unit 200. For example, at least one printing unit 203 is configured as a lithographic printing unit 203, for example an offset printing unit 203, and / or at least one other printing unit 203 is configured as a letterpress printing unit 203, in particular an indirect letterpress printing unit 203.

The inks of the printing cylinders 204 are collected on the printing cylinder 204 and then transferred together to the corresponding substrate 202 at a single printing station. The Simurtan printing unit 200 therefore operates according to an indirect printing method, such as indirect lithography or offset printing and / or indirect letterpress printing, in particular the letterset printing method. Preferably, the Simurtan printing unit 200 is configured as a Simurtan double printing unit 200. In such a Simurtan double printing unit 200, two printing cylinders 204 together form a single printing station 201, at which the substrate 202 is simultaneously printed in two colors.

More preferably, the inking units of all printing plate cylinders 202 associated with a common transfer cylinder 204 are arranged to be movable together away from the printing plate cylinder 202 and are therefore preferably supported in a common subframe.

[0046] During the printing run of the printing press 01, at least one sheet 02, preferably a series of several sheets 02, taken from the substrate supply device 100 is fed to the printing unit 200. The printing unit 200 preferably operates in a duplex printing mode, in which both sides of the substrate 02 are simultaneously colored in the printing station 201. Furthermore, in the printing station 201, a multicolor print image is preferably transferred to the substrate 02 in a single printing step. The multicolor print image is preferably formed from individual colored partial print images that have been previously transferred from several plate cylinders 202 to corresponding transfer cylinders 204 and collected there. At least one printing unit 200 preferably comprises two halves that are substantially identically configured. Each half has a transfer cylinder 204 that is preferably configured as a rubber blanket cylinder 06. The plate cylinders 202, in particular the printing plates arranged on the plate cylinders 202, are preferably each colored with a different printing ink by an inking unit. Each printing cylinder 202 preferably transfers at least one printing image to a corresponding transfer cylinder 204 against which the printing cylinder 202 abuts, thereby preferably forming a multi-color printing image on each transfer cylinder 204, which is then transferred to the substrate 202, preferably in a single step.

[0047] At least one printing unit 200 may include, for example, one or more additional stamping cylinders 204, each of which is also arranged to cooperate with a plurality of plate cylinders 202 (as also illustrated in FIG. 1).

[0048] Alternatively or additionally, the converting machine 01 has a coating device 200 that operates according to another method, for example, the converting machine 01 has at least one screen printing unit and / or at least one flexographic printing unit and / or at least one letterpress printing unit and / or at least one numbering printing unit and / or at least one intaglio printing unit.

The curing section is, for example, a section of a transport path provided for transporting the sheet O2 that overlaps with the working area of ​​the curing device 300, because, for example, the curing device 300, in particular the at least one LED-UV radiation source 302 of the curing device 300, emits corresponding electromagnetic radiation directed towards the curing section 300.

[0051] At least one curing device 300, in particular at least one first curing device 321 and / or at least one second curing device 322, has at least one radiation source 302 for electromagnetic radiation, e.g., infrared radiation and / or UV radiation.

This at least one radiation source 302 for ultraviolet radiation is also referred to as UV radiation source 302. The at least one curing device 300 can provide radiation in the ultraviolet range of the electromagnetic spectrum for drying or curing applied materials to substrates 202 passing through the at least one curing device 300 on a conveying path. The at least one UV radiation source 302 is preferably configured as an LED-UV radiation source 302.
