[0054] The machine 01 used for processing sheet paper 02 is also used for inspecting sheet paper 02. These sheet papers 02 are sheet papers 02 of the corresponding substrate 02. The machine 01 may have other devices for processing sheet paper 02, for example. Examples of these devices include: coating devices, such as primer coating devices and / or printing devices and / or painting devices; or forming devices, such as cutting devices and / or punching devices and / or perforating devices and / or folding devices. Therefore, the machine 01 is preferably designed as an inspection machine 01. For example, the machine 01 may also be designed as a sheet paper processing machine 01, preferably a coating machine 01, and in particular a printing machine 01. If a coating machine 01, and in particular a printing machine 01, is shown above and / or below, the corresponding description also applies to a simple inspection machine 01, provided that there is no contradiction. For example, the machine 01 may be additionally or alternatively designed as a forming machine 01. Preferably, machine 01 is designed as a machine 01 for processing single sheets of securities 02, particularly as a securities processing machine 01 and / or a securities inspection machine 01 and / or a securities printing machine 01. For example, machine 01 is designed as a single-sheet printing machine 01, particularly a single-sheet rotary printing machine 01, or more preferably as a single-sheet securities printing machine 01.

[0055] Machine 01 has at least one inspection device 08; 768 for inspecting single sheets of paper 02. The at least one inspection device 08; 768 is preferably arranged to detect single sheets of paper 02 passing through it. Preferably, machine 01 is equipped with a transport path for transporting single sheets of paper 02. This transport path preferably originates from a substrate feed device 100. The substrate feed device 100 is designed, for example, as a single sheet feed device 100, particularly a single sheet pusher 100. Preferably, machine 01 has at least one single sheet pusher 100. Alternatively, machine 01 has at least one unwinding device and at least one transverse cutting device.

[0056] Machine 01, for example, has at least one sheet-fed processing unit 200; 500; 600; 700. The at least one sheet-fed processing unit 200; 500; 600; 700 is designed, for example, as a sheet-fed printing unit 200; 500; 600; 700. Different printing processes can be implemented depending on the specific embodiment.

[0057] The sheet 02 may be formed, for example, from cellulose-based or preferably cotton-based paper, plastic polymers, or mixtures thereof. The sheet 02 may be uncoated or coated before being inspected and / or processed by machine 01. The sheet 02 may be unprinted, printed once or multiple times, or otherwise mechanically processed. On the sheet 02, it is preferable to arrange multiple printed sheets, particularly banknotes to be produced, side-by-side in a row, and multiple such rows of printed sheets or their printed images are arranged sequentially along the transport direction T, or correspondingly during the processing of the respective sheet 02.

[0058] The substrate feeding device 100 or sheet feeding device 100 of machine 01 is preferably arranged at the beginning of the conveying path for conveying substrate 02, particularly sheet 02. At least one substrate feeding device 100 preferably has, for example, a feeding section 101 designed as a belt table 101. For example, at least one receiving device, preferably designed as a stacking plate, is arranged. On this receiving device, the substrate assembly designed as a sheet stack can be separated. The receiving device is preferably connected to at least one conveying mechanism that ensures that even when the sheet stack is completed, the top sheet 02 of the sheet stack is in a defined position. The substrate feeding device 100 preferably includes a sheet separation mechanism and a sheet conveying mechanism. The sheet separation mechanism is, for example, designed as a separation suction device. The sheet conveying mechanism is, for example, designed as a conveying suction device. Preferably, at least one front stop is arranged. For example, the substrate feeding device 100 has at least one non-stop device for continuously supplying sheets 02 during subsequent stacking. The belt conveyor arranged after the sheet stack is designed, for example, as a suction belt conveyor. For example, at least one pushing device, referred to as a sheet pusher, is arranged, which preferably includes a pushing table and at least one movable front stop. The sheet pusher 100 preferably has at least one vibrating gripper or vibrator. Preferably, a receiving drum 102 is arranged after the vibrating gripper along a conveying path provided for conveying the sheets 02. Preferably, the sheets 02 are transferred from the vibrating gripper to the receiving drum 102. The receiving drum 102 is a rotating conveyor 102.

[0059] Machine 01 preferably has at least one assembly 900 designed as a paper receiving device 900, particularly a sheet-fed paper receiving device 900, which is particularly attached to at least one inspection device 08; 768, and, if necessary, attached to at least one sheet-fed paper processing unit 200; 500; 600; 700. The sheet-fed paper receiving device 900 preferably includes at least one sheet-fed paper feeding system 904, which is particularly designed as a chain feeding system 904 or a chain gripper system 904. The sheet-fed paper feeding system 904, for example, includes a traction mechanism that moves by means of a drive and deflection device, which drives a gripper for conveying the sheet. The gripper has a fixing mechanism for receiving and securing the sheet 02. Grippers, particularly clamping grippers and / or suction grippers for gripping the edges of the sheet, can be used as the fixing mechanism. Using the sheet-fed delivery device 900, individual sheets of paper 02 are preferably placed in the form of a corresponding delivery stack onto at least one conveyor tray, or more preferably one of several conveyor trays designed as pallets or other types. For example, the sheet-fed delivery device 900 includes a sheet-fed guiding device and / or a drying and / or curing device 906. The sheets of paper 02, preferably decelerated by a braking device, rest against a front stop, thereby being placed in an aligned manner onto the corresponding delivery stack. For example, the sheet-fed delivery device 900 is equipped with a non-stop mechanism for uninterrupted removal of the delivery stack.

[0060] In particular, when combined with a paper receiving device 900 that includes multiple stacking positions, in an advantageous improvement, at least one inspection device 768 is arranged after the final alignment device 771 along the conveying path for conveying the single sheets 02. Single sheets 02 deemed to have defective or incorrect printing can then be collected on one of the stacks, while so-called "good single sheets" are placed on another stack.

[0061] For example, the paper receiving device 900 has at least two, more preferably at least three, output stations 901; 902; 903 arranged sequentially along the conveying path for conveying single sheets of paper 02. Therefore, at least one paper receiving device 900 is preferably designed as a multi-stacking paper receiving device 900, particularly at least as a double-stacking paper receiving device 900, at least as a triple-stacking paper receiving device 900, or at least as a quadruple-stacking paper receiving device 900. Output stations 901; 902; 903 are also referred to as stacking paper receiving devices 901; 902; 903. Here, the corresponding output stations 901; 902; 903 or stacking paper receiving devices 901; 902; 903 should be understood as devices specifically for forming the corresponding stacks.

[0062] The conveying path for conveying, in particular, at least partially separated, individual sheets 02 preferably begins at the substrate feed device 100 and / or preferably ends at the sheet delivery device 900. The conveying path for conveying the individual sheets 02 is further preferably such that each segment 11 is preferably a spatial region. Stacks containing multiple sheets 02 are preferably conveyed to the substrate feed device 100 and / or removed from the sheet delivery device 900. The conveying paths of these stacks should not be included in the conveying path for conveying the individual sheets 02. For example, at least one full sheet monitoring device 773 is arranged along the conveying path for conveying the individual sheets 02. This is particularly used to detect the arrival of the individual sheets 02 at the expected time and / or the expected shape of the sides of the individual sheets 02. The full sheet monitoring device 773, for example, has at least one electromagnetic radiation source, particularly visible light, and a sensor for electromagnetic radiation, particularly visible light.

[0063] For a curved conveyor path, the conveying direction T is preferably tangent to the segment and / or point closest to the reference point corresponding to the distance of the set conveyor path, and is configured to convey substrate 02 and / or sheet paper 02 at that segment and / or point. The corresponding reference point is preferably located on the segment and / or point associated with the conveying direction T. Therefore, the conveying direction T preferably extends along the conveyor path configured to convey substrate 02 and / or sheet paper 02. Along the conveyor path configured to convey sheet paper 02, the conveying direction T is determined at each location, specifically the direction T that is tangent to the corresponding location of the set conveyor path and parallel to the direction of movement of sheet paper 02 at that location. The transverse direction A is preferably a direction A that is orthogonal to the conveying direction T and extends horizontally. Preferably, the transverse direction A is orthogonal to the vertical direction V.

[0064] The working width of machine 01 is preferably orthogonal to the dimension of the conveying path 09 extending through machine 01 and / or along the transverse direction A for conveying single sheets of paper 02. The working width of machine 01 is preferably equivalent to the maximum width of single sheets of paper 02 that machine 01 can still process, i.e., particularly the maximum width of single sheets of paper that machine 01 can process. Here, the width of single sheet of paper 02 should be understood in particular as its dimension in the transverse direction A. This is preferably independent of whether the width of single sheet of paper 02 is greater or less than its orthogonal horizontal dimension, which is further preferably the length of single sheet of paper 02. The working width of machine 01 preferably corresponds to the working width of the various components of machine 01. The maximum working width of machine 01 is preferably at least 50 cm, more preferably at least 75 cm, and even more preferably at least 100 cm. Machine 01 preferably has a frame 03 with a particularly fixed position, which has at least two particularly fixed frame sidewalls 04 and 06.

[0065] The machine 01, used for processing and preferably also for processing single sheets of paper 02, has at least one inspection device 08; 768 for performing, in particular, optical inspection of the single sheets of paper 02. The machine 01 has at least one sheet-fed conveying mechanism 07; 708; 709; 711; 712; 713; 714, which defines a segment 11 of a conveying path 09 for conveying the single sheets of paper 02. This segment 11 includes an inspection area 12, wherein the inspection device 08; 768 has at least one, in particular, optical sensor device 13, which is arranged aligned with the inspection area 12. Specifically, the inspection area 12 is a sub-segment of the conveying path 09, defined by the sheet-fed conveying mechanism 07; 708; 709; 711; 712; 713; 714, and specifically a segment detectable by the sensor device 13.

[0088] The corresponding blowing drum 712 is preferably arranged immediately after the corresponding impression cylinder 708, and more preferably immediately before the corresponding alignment cylinder 709, along the conveying path for conveying the sheet paper 02.
