[0016] The purpose of this invention is to provide a printing unit having an alignment device, a non-printing plate type printing area, and a curing device.
[0017] According to the present invention, this objective is achieved by the features of claim 1.
[0018] The printing unit has at least one first printed plate type printing area, which is formed by a pair of cooperating rotating bodies. Following the at least one first printed plate type printing area, the printing unit has at least one first alignment roller, and following the first printed plate type printing area, it also has at least one first unprinted plate type printing area. At least one first print head is assigned to the first unprinted plate type printing area. Following the first unprinted plate type printing area, the printing unit also has at least one first curing device with a first curing region assigned to it. In the region of the first unprinted plate type printing area, the conveying path for conveying the substrate is determined by the first alignment roller or a rotating conveyor immediately preceding the first alignment roller. Thus, a coating medium with alignable particles can be applied to the substrate by means of the printed plate type printing area, and a particularly colorless additive is applied only by at least one print head, thereby selectively curing in the curing device. Therefore, image information can be written into the coating medium using at least one printhead, and then the image information can be fixed. Thus, this image information can be written into the coating medium at very high resolution and in a particularly simple manner.
[0019] In the improved design, the printing unit preferably has the advantage that, in the first curing area of at least one first curing device, the transport path for conveying the substrate is determined by a first alignment roller or a rotating conveyor immediately following the first alignment roller. Since it has been determined by at least one print head which areas should be cured, curing can also be performed on the alignment roller, or, if the alignment is sufficiently stable, after the alignment roller. This allows for installation based on space constraints. Furthermore, a relatively simple curing device can be used.
[0020] In the improved design, the printing unit preferably features an advantage in that a supply reservoir connected to at least one first printhead via piping technology contains a particularly colorless additive, specifically designed to alter the curing properties of the applied material. This material is, in particular, a mixture of a coating medium, for example designed as printing ink, and this additive. Thus, image information can preferably be generated simply by distributing it onto the substrate, without affecting the color characteristics of the coating medium.
[0021] The first printing plate area is designed as a screen printing area. This allows for the production of a particularly thick layer of coating medium with a correspondingly clear and visible effect.
[0022] In the improved design, the printing unit preferably features a rotary conveyor arranged immediately after the impression cylinder of the first plate-type printing area along a conveying path for transporting the substrate. This rotary conveyor is designed as a conveying drum and / or a blowing drum and / or a suction drum, and / or as a rotary conveyor that operates non-contactly without regard to gripper contact. Therefore, the substrate can preferably be transported without negatively impacting the coating medium applied by the plate-type printing area.

In the improved embodiment, the printing unit preferably has the advantage of having at least one second curing device after the second blank printing along a transport path for conveying the substrate, the second curing device having a second curing area assigned to it. Advantageously, this results in multiple image areas with various different pigment orientations by subjecting the uncured coating medium to multiple alignments, adding additives to certain areas, and then curing only in these areas, so that subsequent uncured areas can also be processed in this way.
[0026] In the improved embodiment, the printing unit preferably has the advantage that: in the region of the second blank printing plate area, the conveying path for conveying the substrate is determined by the second alignment roller or a rotating conveyor immediately preceding the second alignment roller; and / or in the second curing region of at least one second curing device, the conveying path for conveying the substrate is determined by the second alignment roller or a rotating conveyor immediately following the second alignment roller. In the improved embodiment, the printing unit preferably has the advantage that: each printed plate printing area of the printing unit is arranged before and / or after the second blank printing plate area.
[0027] In the improved design, the printing unit preferably has the advantage of having, in a supply reservoir connected to at least one second printing head via piping technology, an additive, particularly colorless, and especially an additive for altering the curing properties of the applied material, arranged therein.

The impression cylinder 708 and the plate cylinder 752, particularly designed as a screen printing plate cylinder 752, together form the printing area 758, which is specifically designed as a screen printing area 758.
[0078] In particular, the printing unit 700, designed as a screen printing unit 700, has, for example, at least one conveyor drum 711. The corresponding conveyor drum 711 typically has at least one gripping device for feeding single sheets of paper. The corresponding conveyor drum 711 preferably has at least one base.

The at least one sheet paper guiding device preferably has at least one inner surface whose shape corresponds to a segment of the drum housing, the axis of which is the same as the rotation axis 719 of the blowing drum 712. The at least one sheet paper blowing device is used to generate an airflow from the inside toward the inner surface of the sheet paper guiding device. Thus, the corresponding sheet paper 02 held by the gripping device can be further conveyed about the rotation axis 719, while the inward-facing side of the sheet paper is not touched by components of the printing unit 700, specifically designed as a screen printing unit 700, regardless of the contact surface of the fixing mechanism.
[0082] The corresponding blowing drum 712 is arranged along a conveying path for conveying the substrate 02, preferably immediately after the corresponding impression cylinder 708 and / or immediately before the corresponding alignment cylinder 709. In this way, a single sheet of paper 02 can be conveyed from the impression cylinder 708 to the alignment cylinder 709 or from the alignment cylinder 709 to another alignment cylinder 709, without the newly printed sheet coming into contact with an object and thus damaging the applied print.
[0083] Preferably, at least one pre-alignment device 767 is arranged, for example, in the region of the blower roller 712 and / or the suction roller 713 and / or the transfer roller 711. The at least one pre-alignment device 767 is preferably a component of a corresponding alignment device 771.

The pre-alignment device 767 preferably has at least one, and more preferably, multiple, electromagnets and / or permanent magnets.
[0084] In particular, the printing unit 700, designed as a screen printing unit 700, has, for example, at least one suction drum 713. The corresponding suction drum 713 typically has at least one gripping device for feeding single sheets of paper. The corresponding suction drum 713 preferably has at least one base. The at least one gripping device has a fixing mechanism for receiving and securing the single sheet of paper 02. The fixing mechanism is preferably arranged on the base and / or movably arranged with the machine.

The suction drum 713 preferably has a resting surface for the single sheet of paper 02. The at least one gripper preferably has at least one movable gripping finger, which is movably arranged relative to the base of the suction drum 713 and / or the resting surface of the suction drum 713.
[0085] The placement surface of the suction drum 713 preferably has suction openings, particularly for sucking up ambient air and / or individual sheets of paper 02. If individual sheets of paper 02 are arranged on the placement surface of the suction drum 713, the leading edge of the individual sheet is preferably held by a gripper.

Preferably, at least one inspection device 402; 403 is arranged, more preferably aligned with the placement surface of the rotating conveyor 407 designed as the suction drum 713. By sucking up the corresponding individual sheet of paper 02, the position of the individual sheet on the suction drum 713 is particularly stable. For example, this enables particularly high-precision inspection. In particular, in conjunction with a paper receiving device 900 including multiple stacking positions, in an advantageous improvement, at least one inspection device 402; 403 is arranged along the conveying path provided for conveying the substrate 02 after the final alignment device 771. The at least one inspection device 402; 403 operates, for example, by incident light and preferably, in addition to having a light source pointing towards the transport path for transporting the substrate 02, also has a camera pointing towards the point of contact between the inspection device and the transport path for transporting the substrate 02. Sheets 02 deemed defective or having defective prints can then be collected on one stack, while so-called qualified sheets are placed on the other stack.
[0086] As described above, the printing unit 700, particularly designed as a screen printing unit 700, preferably has at least one alignment roller 709, which is specifically designed as a rotating conveyor 709. The corresponding alignment roller 709 is preferably designed as a magnetically effective alignment roller 709. Preferably, the sheet paper 02 is fed by means of the corresponding alignment roller 709, and here, the magnetic particles of the previously applied and not yet dried coating medium are oriented according to the distribution pattern of the magnetic field lines emanating from the corresponding alignment roller 709. The corresponding alignment roller 709 preferably has a plurality of magnetic field-generating elements, simply referred to as magnetic elements, in its outer circumferential region, which are specifically used to orient at least a portion of the magnetic or magnetizable particles applied to the corresponding sheet paper 02. The magnetic elements may be formed of permanent magnets with or without engravings, by electromagnets, or by a combination of one or more permanent magnets and / or one or more electromagnets. These magnets can be removable and / or rotatably arranged on the roller base, and / or adjustable individually or in groups, relative to their axial and / or circumferential positions, and can form corresponding alignment rollers 709 together with the magnets. In the case of multiple sheets of paper 02, for example, multiple rows, such as at least four rows, of each multiple, such as three to eight, particularly four to seven, magnetic elements spaced apart from each other transversely to the transport direction T are arranged in a matrix around the circumference. By feeding the sheets of paper 02 onto the corresponding alignment rollers 709, the particles are aligned or oriented by means of the magnetic field lines induced by the magnetic elements, which also pass through the corresponding sheets of paper 02 when necessary.
[0087] Magnetic elements are arranged or can be arranged on multiple, for example, three to eight, particularly four to seven, axially spaced and preferably positionable along the axial direction A, wherein at least one, preferably multiple, for example, between two and twelve, advantageously between five and ten, magnetic elements are arranged or can be arranged sequentially and preferably positionably in the circumferential direction on or in said annular elements.

[0088] Preferably, the corresponding alignment rollers 709 are supported between the frame sidewalls 702; 703 of the printing unit 700, which is specifically designed as a screen printing unit 700, in such a way that the alignment rollers can be removed, particularly without removing one of the frame sidewalls 702; 703, for replacement or for performing equipment work. However, this means "as planned" or "in accordance with operation" removal or reinsertion, rather than disassembly or dismantling of the associated structural unit. For this purpose, for example, a torsion-resistant, separable connection is provided at least on the drive side between the alignment rollers 709 or roller journals and the adjacent drive shaft, the separation portion of which is located within the net width between the frame sidewalls 702; 703.
[0089] Preferably, at least one external magnet device 774 is arranged, which is particularly designed as a simultaneous magnet device 774. This at least one external magnet device 774 is preferably positioned fixedly, at least during the printing run. This at least one external magnet device 774 is preferably assigned to a corresponding alignment roller 709. This at least one external magnet device 774 is preferably a component of the alignment device 771, particularly also belonging to the alignment device 771 of the associated alignment roller 709. The external magnet device 774 is preferably designed such that the external magnet device extends around the associated alignment roller 709 in an angular direction. The external magnet device 774 preferably has at least one, and more preferably multiple, electromagnets and / or permanent magnets, and preferably cooperates with the magnetic device of the corresponding alignment roller 709.
[0090] In alternative or additional improvements, particularly a printing unit 700 designed as a screen printing unit 700, is preferably advantageous in that: the printing unit has at least one screen printing plate cylinder 752, which forms a screen printing portion 758 with an impression cylinder 708, and at least one alignment cylinder 709 is arranged after the impression cylinder 708 along a transport path provided for transporting the substrate 02, the alignment cylinder having a plurality of elements that generate a magnetic field in the region of its outer circumference.
[0091] The printing unit 700 is designed, for example, as a sheet-fed printing unit 700. The printing unit 700 preferably has at least one first printed plate type printing portion 758, formed by a pair of cooperating rotating bodies 708; 752. Here, the term "first printing portion" is preferably understood only for distinction and is unrelated to the order in which the sheet passes through the printing unit 700. The printing unit 700 preferably has at least one first alignment roller 709 along a transport path provided for conveying the substrate 02, after the first printed plate type printing portion 758, for example, directly, preferably indirectly, after the first printed plate type printing portion 758. Preferably, the printing unit 700 has at least one first unprinted plate type printing portion 787 along the transport path provided for conveying the substrate 02, after the first printed plate type printing portion 758, and assigns at least one first print head 791 to the first unprinted plate type printing portion. Preferably, the printing unit 700, along a transport path provided for transporting the substrate 02, after the first unprinted printing area 787, has at least one first curing device 772, the first curing device having a first curing area 788 assigned thereto.
[0092] In alternative or additional improvements, the printing unit 700 is preferably advantageous in that: in the area of the first blank printing plate portion 787, the conveying path for conveying the substrate 02 is determined by the first alignment roller 709 or a rotary conveyor 711; 712; 713 arranged adjacent to the first alignment roller 709, for example, a conveying drum 711 and / or a blowing drum 712 and / or a suction drum 713 and / or a non-contact rotary conveyor 711; 712; 713 that does not consider contact with the gripper.
[0093] In alternative or additional improvements, the printing unit 700 is preferably advantageous in that: in the first curing area 788 of at least one first curing device 772, the conveying path for conveying the substrate 02 is determined by a first alignment roller 709 or a rotating conveyor 711; 712; 713 arranged immediately after the first alignment roller 709, for example, a conveying drum 711 and / or a blowing drum 712 and / or a suction drum 713 and / or a non-contact rotating conveyor 711; 712; 713 that does not require contact with grippers.
[0094] In alternative or additional improvements, the printing unit 700 is preferably advantageous in that a particularly colorless additive is arranged in a supply reservoir 789 connected to at least one first printhead 791 via piping technology. This additive is specifically designed to alter the curing properties of the applied material, which is preferably a mixture of a coating medium, particularly printing ink, and the additive. For example, this change in curing properties is the generation or increase of a particularly radiation-induced reactivity or curing reaction and / or the rate of the curing reaction. Suitable radiation is, for example, UV radiation and / or electron radiation. The additive is preferably a crosslinking agent. Preferably, the coating medium applied and / or applicable via the first printed plate printing area 758 does not itself possess radiation-induced reactivity or curing reaction. Thus, the portion of the coating medium to be cured can be determined by application in the unprinted plate printing area 787. Therefore, orientation, area selection, curing of the selected area, and then reorientation and re-curing of previously uncured areas can be performed repeatedly and sequentially.
[0095] In alternative or additional improvements, the printing unit 700 preferably features a first plate-type printing area 758 designed as a screen printing area 758. The first plate-type printing area 758 is then formed, in particular, by cylinders 708 and 752, one of which is a plate cylinder 752, and the other is a mating impression cylinder 708. The plate cylinder 752 is preferably designed as a screen printing plate cylinder 752. As an alternative to the screen printing area 758, the first plate-type printing area 758 can be designed as a flexographic printing area, a letterpress printing area, a gravure printing area, or a planographic printing area.
