Abstract

The invention relates to a printing press with a device for attaching at least one washing device for cleaning a cylinder of a printing unit and/or coating unit, the device for attaching comprising at least one locking device on the at least one washing device, the at least one locking device being arranged such that it can rotate about an axis of rotation .

Description

The invention relates to a printing press with a device for attaching at least one washing device according to the preamble of claim 1 or a method for attaching at least one washing device according to claim 17.

Washing devices for rubber and impression cylinders are used in printing presses, among other things. These are often designed to be removable so that they can be cleaned and/or a washing cloth can be changed. In order to moisten such a wash cloth, media lines with water and/or cleaning liquid lead to the wash cloth.

through the DE 10 2004 062 115 A1 a washing device for lateral surfaces of rotating cylinders is known. The rubber blanket washing device has a clean-cloth roll and a dirty-cloth roll. A web of cleaning cloth is pressed against a lateral surface of a cylinder by means of a pressing element.

The object of the invention is to provide a printing press with a device for attaching a washing device and a method for attaching a washing device.

The object is achieved according to the invention by the features of claim 1 and claim 17 .

The advantages that can be achieved with the invention consist in particular in the fact that a washing device can be fastened in a simple and safe manner in a printing unit, in particular close to a cylinder and/or blanket cylinder to be cleaned, by means of a fastening device. In particular, the washing device can be locked and/or unlocked with little effort.

The device for fastening is designed in such a way that when fastening, the washing device is placed in the correct position relative to the cylinder to be cleaned and is locked at the same time. Preferably, both processes happen with one movement. In particular, the simultaneously running processes can prevent a one-sided clamping or faulty clamping, for example only on one side, of the washing device. A secure locking on both sides is thus guaranteed. An eccentric locking element results in the washing device being guided into the end position by turning a locking means and being locked at the same time. In particular, this is done via a recess that is matched to the locking element. In particular, a linear movement of an eccentric element is converted into a likewise linear and differently directed movement of a locking means. When the washing device is unlocked and/or removed, this principle takes place in reverse order.

Another advantage that can be achieved with the invention is that the correct positioning and locking of the washing device can be recognized. In particular, malfunctions of the machine can be detected in this way.

A further advantage that can be achieved with the invention is that a media connection for detergent and water can be designed in a spring-loaded manner. In particular, a high expenditure of force is required for the sealing. In particular, a sufficiently high pressure and/or sealing is ensured by the fastening device. Such a media connection and/or media coupling is particularly preferably only arranged on one side. The sufficiently high pressure prevents tilting and/or locking on one side only.

Exemplary embodiments of the invention are shown in the drawings and are described in more detail below.

In one embodiment, individual drives are provided for the separating suckers 12 and the transport suckers 13 . Individual drives are understood here as controllable drives which are assigned to one or a group of working elements (sheet separating elements 12 and/or sheet transport elements 13) to drive them, in particular to drive them independently of the drive (preferably all) other working elements or groups of working elements, in particular without to be coupled via a mechanical and/or positive drive connection to drives of other working elements that are driven individually or also in one or more groups.

Sheets B of the stack of sheets 09 are positioned on stop elements 16, in particular with the front edge of the sheet on stop surfaces of front stops 16. A sheet flap 17 can form an approximately vertical continuation of the stop surfaces of the front stops 16 in the upper region of the stack of sheets 09. The curved flap 17 is, for example, via a flap shaft 18, to which it is connected in a rotationally fixed manner, in drive connection with a drive, preferably an individual drive. The sheet flap 17 can thus be pivoted out of the position forming a straight continuation of the stop surfaces and thus brought into a position that supports the guidance of the sheets B to the downstream belt table 02. At the back of the sheet stack 09 are preferably blowing devices 19, z. B. Blowers 19, for pre-loosening the sheets B lying in the upper region of the sheet stack 09 and for forming an air cushion supporting the sheets B during conveying in the sheet transport direction 15.

The sheet-fed printing press can contain a turning device 78 for turning the sheets B to be printed. The turning device 78 is preferably located between the printing units 05; 06 of the machine, in particular between the pressure cylinders 34. This turning device 78 is preferably configured in such a way that it can be converted from recto printing to verso printing so that the machine operates in either recto printing mode or in recto and verso printing mode. Verso printing means that a sheet B, after being printed by a number of printing units 05; 06 is turned to the subsequent printing units 05; 06 to print on the back.

One or more drying devices 68 are preferably arranged above and/or below the sheet path in sheet delivery 08. In a preferred embodiment, the path between the last coating or printing unit 07; 05; 06 and the sheet delivery 08 can be extended, in particular by connecting a drying unit in between, in order to gain space for the arrangement of further drying devices 68. If required, intermediate drying can also take place in the machine by means of drying devices 68 assigned to the cylinders. This intermediate drying can also be carried out by a drying unit arranged in the machine.

The sheet delivery 08 of a sheet-processing machine, in this case in particular a sheet-fed printing press, in particular a sheet-fed offset rotary printing press, contains a sheet-guiding system 69 arranged downstream of a sheet-guiding system, in this case as a sheet-guiding cylinder, specifically impression cylinder 34, which is embodied in particular as a chain conveyor system 69. The sheet conveying system 69 contains traction means which are moved via drive and deflection means and which drive gripping devices 70 for sheet conveying.

The sheet guiding device has sheet guiding plates facing the gripper carriage 70, which are provided with blast air nozzles and extend across the width of the machine. Blower boxes are arranged under the sheet guide plate, via which the blown air nozzles are supplied with blown air, so that a supporting air cushion is formed between the sheet guide plate and the sheets B transported by the gripper carriage 70 . In order to be able to regulate heating of the sheet guide plate in the area of the dryer, a coolant circuit can be integrated. In order to prevent the sheets B from sticking together on the delivery pile 71, a release agent application device, in particular a powder device, preferably combined with a device for sucking off the powder, is preferably provided in the area of the sheet delivery 08.

In front of the delivery pile 71 there is a braking device, not designated further, for decelerating the sheets B released by the gripper carriage 70 . The braking device can contain rotating suction rings and/or circulating suction belts or can be designed as a follow-up gripper system. The sheets B decelerated by the braking device come into contact with front stops and are thus deposited on the delivery pile 71 in an aligned manner. The delivery pile 71 is preferably lowered by a pile lifting drive by the thickness of the deposited sheet, so that the surface of the pile always assumes an approximately constant level.

To change the z. B. transport documents 76 designed as pallets 76 to avoid stopping the sheet-fed printing press, the sheet delivery 08 can be equipped with a non-stop device, not shown. This mainly includes an auxiliary stack carrier, for example in the form of a slatted table that can be rolled up, in particular also referred to as a roller blind. The roller blind has rods which are movably connected to one another. In its rest position, it is arranged rolled up in front of the delivery pile 71 and is unrolled between two sheets B into a working position lying parallel to the surface of the delivery pile 71 to change the pile while the sheet-fed printing press is running in the sheet transport direction 15 . In this position above the delivery pile 71, this lattice table temporarily accepts the incoming sheets B, so that an auxiliary pile is formed. In the meantime, the main stack can be removed and replaced by a new transport base 76, in particular a pallet 76. At the end of the stack changing process, the roller blind is pulled back into its rest position and the auxiliary stack is placed on the new pallet 76.

At least one drive motor (not shown) is assigned to the sheet-fed printing press.

In a first embodiment, this is at least one drive motor z. B. designed as a main motor and drives z. B. a closed train of wheels that forms a drive system. The drive assembly includes in particular the pressure cylinder 34; 36, the transfer drums 35, the blanket cylinders 33, the plate cylinders 32, the coating unit 07 and the inking units 42.

H. without a mechanical and/or form-fitting drive connection to drives of the other functional units and the drive system comprising the main motor. In an embodiment that improves on the first embodiment, at least the plate cylinders 32 are separated from the drive system and are driven by separate drives, in particular individual drives, that are assigned only to the respective plate cylinder 32 . H. without a mechanical and/or positive drive connection to the drives of the other plate cylinders 32 and to the drive assembly comprising the main motor and to the drives of other functional units such as substrate feed system 01, ink fountain rollers 44 and/or dampening units 51. The individual drives of the plate cylinders 32 can in particular be formed by so-called direct drives, with the direct drive including an above-mentioned Individual drive is understood, in which the drive motor or its rotor, preferably without intermediate gear elements, is connected directly or possibly via a coupling in a mutually coaxial arrangement to the drive shaft, in particular the journal, of the plate cylinder 32. The drive motor is preferably designed in such a way that the interposition of a gear can be dispensed with. The peripheral speed of the plate cylinders 32 is adapted to the peripheral speed of the cylinders interacting with the plate cylinders 32 . According to another embodiment, several of the works 05; 06; 07, preferably any of the works 05; 06; 07 its own, the drive network of the relevant plant 05; 06; 07 driving drive motor, but without a mechanical and/or positive drive connection to drives of other movements 05; 06 to be paired. For example, the coating unit 07 also has at least one drive of its own. Such a drive is, for example, a direct drive and/or an auxiliary drive. Such an auxiliary drive can preferably be decoupled from the main drive and used, for example, to position individual cylinders, in particular the forme cylinder 63 . The sheets B are in the z. B. provided as a stack of sheets 09 09 to be printed. The uppermost sheet B of the stack of sheets 09 is grasped by the sheet separator 14 and forwarded for further processing. This happens e.g. B. as follows:

The sheet separating elements 12 are guided against the top of the stack of sheets 09, grasp the uppermost sheet B and lift it off the underlying sheet B by being moved back into their starting position. The blowers blow under the sheet B held by the sheet separating elements 12 and thus separate it over its entire surface from the underlying sheet B. The sheet B held by the sheet separating elements 12 and separated over its entire surface is gripped by the sheet transport elements 13 and released by the sheet separating elements 12. The sheet transport elements 13 promote the detected sheet B in the sheet transport direction 15, with the beginning of the sheet transport, the sheet flap 17 can be pivoted downwards, so that the sheet B with the sheet leading edge to the z. B. designed as a belt table 02 conveyor line 02 can be transported. The timing rollers 25 are initially lifted from the drive roller 20 and set down on the respective sheet B when this is in the gap between the timing rollers 25 and the drive roller 20. The respective sheet B is then released by the sheet transport elements 13 . The supported by the sheet transport members 13 in the sheet transport direction 15 sheets B are in compliance with a predetermined scale spacing on the z. B. configured as a belt table 02 conveyor line 02 and guided by this or this in the work cycle of the sheet-fed printing press against the front lays 27 and can then be drawn off by the sheet acceleration means 04 embodied, for example, as a rocking gripper 04.

The grippers z. B. of the swing gripper 04 transfer the sheet B to the gripper of the feed drum 29, through which the sheet B is transferred to the gripper system 57 of the impression cylinder 34 of the first printing unit 05.

• Die im z. B. im als Farbkasten 43 ausgebildeten Farbvorrat 43 bevorratete Farbe, insbesondere Druckfarbe wird zonenweise dosiert auf die Farbaufnahmewalze 44, z. B. Farbkastenwalze 44, gebracht und bevorzugt von dem periodisch hin und her bewegten Farbheber 47 als Farbstreifen auf die z. B. als Farbreibwalze 48 ausgebildete erste Farbwerkwalze 46 abgelegt. Diese überträgt die Farbe über durch Friktion angetriebene Farbwerkwalzen 49 auf die Farbreibwalzen 48. Über weitere Farbwerkwalzen 45 wird die Farbe auf die Farbauftragswalzen 50 übertragen und gelangt dadurch auf die auf dem Formzylinder 32 aufgespannte Druckform, wobei in Drehrichtung 53 des Formzylinders 32 gesehen vor dem Auftrag der Farbe durch die Farbauftragswalzen 50 der Auftrag von Feuchtflüssigkeit durch die Feuchtauftragswalze 52 erfolgen kann.

The sheet B now on the impression cylinder 34 is inked by the inking unit 42 via the forme cylinder 32 and in the form of an offset printing unit via the transfer cylinder 33 . This happens e.g. B. as follows:

• The z. B. designed as an ink fountain 43 color reservoir 43 stored color, especially ink is zoned metered onto the ink pickup roller 44, z. B. ink fountain roller 44, brought and preferred by the periodic reciprocating ink lifter 47 as a color stripe on the z. B. formed as an inking roller 48 first inking unit roller 46 is stored. This transfers the ink via friction-driven inking unit rollers 49 to the inking rollers 48. The ink is transferred to the inking unit rollers 50 via further inking unit rollers 45 and thus reaches the printing forme clamped on the forme cylinder 32, with this before the application as seen in the direction of rotation 53 of the forme cylinder 32 of the color through the inking rollers 50, the application of dampening liquid through the dampening form roller 52 can take place.

The color deposited on the printing form is transferred to the blanket cylinder 33 in accordance with the motif and from there to the sheet B guided by the impression cylinder 34 .

• Der Bogen B wird von dem Greifersystem 57 des Druckzylinders 34 an das Greifersystem 59 der Übergabetrommel 35 übergeben und so weiter durch die gesamte Bogendruckmaschine geführt. In den einzelnen Druckwerken 05; 06 wird dann über die betreffenden Übertragungszylinder 33 die Farbe auf den Bogen B aufgebracht.

The sheet B is now transferred from the first printing unit 05 to the following printing unit 06 and, if necessary, subsequent further printing units. This happens e.g. B. as follows:

• The sheet B is transferred from the gripper system 57 of the impression cylinder 34 to the gripper system 59 of the transfer drum 35 and so on through the entire sheet-fed printing press. In the individual printing units 05; 06, the ink is then applied to the sheet B via the relevant transfer cylinder 33.

• Der auf der Speichertrommel 80 liegende, im Schöndruck bedruckte Bogen B wird vom Bogenhaltesystem 83 im Bereich der Bogenvorderkante geführt und zusätzlich von einem als Sauggreifer des Saugersystems 84 ausgebildeten Bogenhaltesystem 84 im Bereich der Bogenhinterkante fixiert. Nachdem die Bogenvorderkante den Tangentenpunkt zwischen Speichertrommel 80 und der nachfolgenden Wendetrommel 81 passiert hat, wird sie vom Bogenhaltesystem 83 freigegeben. Während die Bogenhinterkante den Tangentenpunkt zwischen Speichertrommel 80 und Wendetrommel 81 passiert, wird sie vom Wendegreifersystem 82 der Wendetrommel 81 übernommen und vom Bogenhaltesystem 84 der Speichertrommel 80 freigegeben, so dass die Bogenhinterkante dann zur Bogenvorderkante wird.

On the way of the sheet B through the sheet-fed printing press, if a turning device 78 is present, the sheet B can also be turned and printed on its back. The operation of the sheet holding system described in the embodiment in the perfecting mode is z. B. the following:

• The straight-printed sheet B lying on storage drum 80 is guided by sheet holding system 83 in the area of the sheet leading edge and additionally fixed by a sheet holding system 84 designed as a suction gripper of suction system 84 in the area of the sheet trailing edge. After the leading edge of the sheet has passed the tangent point between the storage drum 80 and the subsequent turning drum 81, it is released by the sheet holding system 83. While the trailing edge of the sheet passes the tangent point between storage drum 80 and turning drum 81, it is taken over by the turning gripper system 82 of the turning drum 81 and released by the sheet holding system 84 of the storage drum 80, so that the trailing edge of the sheet then becomes the leading edge of the sheet.

After the sheet B has passed the printing units 05; 06 has passed, it can be provided with a coating layer in one or more coating units 07 by the coating forme cylinder 63. The gripper system of the pressure cylinder 61 then transfers the sheet B to z. B. the chain conveyor system 69 of the sheet delivery 08.

The gripped at the leading edge sheets B are z. B. out on a track that faces up. The sheets B are dried by the drying devices 68 provided and z. B. covered with powder. The sheets B are transported by the gripper carriage 70 up to the height of the delivery pile 71 and deposited there on it.

Each printing unit 05; 06 has the semi-automated and/or automated plate changing device 41. Via such a plate changing device 41, the respective printing unit 05; 06 Printing plates supplied and/or printing plates changed. When a printing plate is changed, for example after the end of a print job, a printing plate clamped on the forme cylinder 32 and held by the fastening means 40 is released and guided out of the printing press via the plate changing device 41 . A new printing plate is then introduced, preferably automatically, into the printing press by the plate changing device 41 and clamped on the forme cylinder 32 by the fastening means 40 . The plate change can be detected in a control device by various sensors. As a result, processes stored in the control device can be started. Such a process is, for example, degumming and/or developing a printing plate in the printing press.

In an alternative or additional embodiment, the method for developing runs at the same time and/or partially offset to washing of a rubber cylinder and/or impression cylinder. To wash the rubber blanket and/or impression cylinder, a washing device 86 is connected to a cylinder 33 to be cleaned; 34; 63 of a printing unit 05; 06 and/or a coating unit 07, for example a blanket cylinder 33 and/or impression cylinder 34 and/or coating unit cylinder 63. Such a washing device 86 has, for example, at least one washing cloth 89 and/or the at least one cleaning cloth 89. In another embodiment, the at least one washing device 86 is turned on to the printing cylinder 34 for washing the printing cylinder. In a preferred embodiment, the washing device 86 is designed as a blanket cylinder washing device 86 . The at least one washing device 86 is preferably attached by means of the at least one attachment device 90 relative to the at least one cylinder 33; 63 aligned and locked arrangable and / or arranged. More preferably, the at least one washing device 86 can be transferred from an unlocked state to a locked state by means of the fastening device 90, for example by pivoting the at least one locking means 96, and/or is arranged in a transferred manner.

The at least one washing device 86 preferably has at least one washing cloth unwinder 93, in particular a clean cloth roll 93, and at least one washing cloth winder 94, in particular at least one dirty cloth roll 94. At least one wash cloth 89 and/or the at least one cleaning cloth 89 runs in a wash cloth direction W and/or winding direction W from the at least one clean cloth roll 93 to the at least one dirty cloth roll 94. The at least one wash cloth 89 and/or the at least one cleaning cloth 89 is rolled by means of at least one support element 91 and/or one pressing element 91, which is preferably designed as at least one rubber membrane 91, on a cylinder 33 to be cleaned; 34; 63, preferably a blanket cylinder 33, of a printing unit 05; 06 and/or a coating unit cylinder 63 of a coating unit 07. The at least one clean cloth roll 91 is mounted in a housing by means of a spindle and the dirty cloth roll 94 by means of a further spindle. The at least one washing device 86 also includes a spray tube 105 for moistening the at least one washcloth 89 and/or the at least one cleaning cloth 89. The at least one washcloth 89 and/or the at least a cleaning cloth 89 rolled onto the at least one dirty cloth roll 94.

The at least one washing device 86 is attached to the printing unit frame 87 and/or coating unit frame 87, preferably directly and/or indirectly with at least one side plate 88 and/or suspension 88 arranged in between. A washing device 86 is preferably attached by means of an attachment device 90 . For this purpose, the device for fastening 90 comprises at least one locking means 96 arranged on the washing device 86, in particular a locking rod 96 and/or a locking spindle 96. The at least one locking means 96 can preferably be rotated and/or pivoted by at least 90°, for example, more preferably at least and /or arranged precisely and/or with a deviation of +/-10% by 180° and/or rotatable about an axis of rotation 101 on the at least one washing device 86. The at least one locking means 96 is preferably configured with a cylindrical and/or oval cross section. In a first preferred embodiment, the at least one locking means 96 and/or the at least one locking bar 96 extends over the entire width of the at least one washing device 86 and has end faces, each with an end face 106, on the two sides furthest away in transverse direction A . A handle 95 for pivoting and/or rotating the at least one locking means 96 and/or the locking bar 96 is preferably arranged on the at least one locking means 96 and/or the locking bar 96. For example, by pivoting and/or rotating the locking means 96 and/or the locking rod 96, the at least one washing device 86 is transferred from an unlocked to a locked position or vice versa.

At least one eccentric element 97 and/or locking element 97 and/or eccentric element 97 is preferably arranged eccentrically at a distance A1 from the axis of rotation 101 on the end face 106 . The distance A1 is preferably the distance A1 between the axis of rotation 101 of the locking means 96 and the axis of rotation 102 of the at least one locking element 97. The at least one locking element 97 is preferably embodied as a bolt 97 and protrudes in the transverse direction A out of the plane of the end face 106, for example at least 0.5 cm to 2 cm or more, outwards. A diameter of the locking element 97 is preferably less than half the diameter of the locking rod 96.

In a further preferred embodiment, the at least one locking bar 96 is not designed as a continuous locking bar 96, but rather as two locking means 96 and/or locking disks 96, each at the outer ends of the two working widths in transverse direction A. In particular, each locking disk 96 also points outwards facing end face 106 and one axis of rotation 101 each. In particular, two connected end faces 106 are not necessary in this embodiment, but these are separate from one another and can be operated separately from one another.

The at least one locking means 96 with the at least one locking element 97 can be fastened and/or fastened and/or positioned in a recess 98 of the printing unit frame 87 and/or coating unit frame 87 for fastening the washing device 86. The recess 98 is preferably on the at least one suspension 88 and/or directly on the at least one printing unit frame 87 and/or coating unit frame 87 arranged. The fastening device 90 preferably comprises the at least one locking means 96 and the at least one locking element 97 and the recess 89 for hanging in the washing device 86.

The at least one recess 98 is preferably formed with two levels. In particular, the at least one recess 98 has at least two different parts 103; 104 in the at least two levels. Preferably, the plane with the first part 103 is further inside in the working width and the second plane with the second part 104 is further outside in the working width. The first part 103 of the recess 98 in the first plane is preferably matched to the locking means 96 and/or the locking rod 96 and the second part 104 of the second plane is matched to the at least one locking element 97 and/or the bolt 97. In particular, “matched” means a size and/or extent of the recess 98 that corresponds to the diameter of the respective locking means 96 and/or the respective locking element 97 at least at some points. More preferably, coordinated also means an at least partially similar rounding and/or curvature of the recess 98 to the at least one locking means 96 and/or the at least one locking element 97. In order to convert the unlocked state into the locked state, the at least one locking means 96 is arranged in a manner transferred from an unlocked position in the recess 98 into a locked position.

In particular, the recess 98 is open to one side so that the washing device 86 can be inserted into the recess 98 . In particular, it is thus ensured, and in particular with the eccentric arrangement of the at least one locking element 97, that the washing device 86 is always hung in the same orientation. The first part 103 of the recess 98 is designed in particular such that the at least one locking means 96 can move in a direction, for example a transport direction and/or a direction perpendicular to the guiding direction of the second part 104 of the recess 98. In particular, this movement comes about as a result of the eccentric arrangement of the at least one locking means 96 . This arrangement means that the at least one washing device 86 can be positioned relative to the cylinder 33 to be cleaned; 34; 63 are positioned. In addition, the recess 98 in the first part 103 is adapted to the cross-sectional shape, so that the at least one locking means 96 is held in two positions. In the first position and/or the hanging position and/or the unlocked position, the at least one locking means 96 is located in the recess 98 and, apart from the hanging direction and/or the vertical direction V, can only be moved in one direction. In particular, movement in other directions is blocked by adapting the rounding of the recess 98 to the cross-sectional shape. In the locked position, in particular, movement counter to the hanging direction and/or the vertical direction V is blocked, and movement in other directions is also blocked by an adapted rounding to the cross-sectional shape. A vertical direction V is preferably a vertical direction with respect to the printing machine. The at least one washing device 86 is preferably suspended from above. In another embodiment, the vertical direction V preferably describes the direction opposite to the hanging direction. The at least one locking element 97 is preferably arranged at least partially linearly guided by the second part 104 of the recess 98 .

In addition, in addition to the recess 98, there is another guide, preferably with only one degree of freedom, in particular a linear guide, on the suspension 88. An additional bolt is present on the washing device 86, which is inserted into the further guide when it is inserted. In particular, the further guidance ensures that the washing device 86 is correctly positioned when it is locked. In particular, the washing device 86 is also guided into the correct position in the further guide when rotated.

In the locked position of the fastening device 90, the at least one locking means 97 is arranged by arranging the at least one locking element 97 in the vertical direction V above the center and/or the axis of rotation 101. In addition, with the arrangement of the at least one locking element 97 in the second part 104 of the recess 98 and the blocking in directions other than the vertical direction V, the at least one locking means 96 is arranged secured against twisting. In addition, the device for fastening 90 preferably has a spring-loaded pressure piece for additional securing of the at least one locking means 96. The at least one locking means 96 is held in position and locked in the locked position by the at least one locking element 97 .

The second part 104 of the recess 98 is designed in particular in such a way that the at least one locking element 97 can only move in the vertical direction V. In particular, the at least one locking element 97 is ver by the second part 104 of the recess 98 vertically guided. When the locking means 96 is rotated, the locking element 97 is moved in the vertical direction V and exerts pressure on the locking means 96 in the transport direction T, in particular due to the eccentric arrangement. In particular, the at least one locking means 96 is transferred from a first position, in particular an unlocked position, to a second locked position. The recess 98 in the second position of the at least one locking means 96 is arranged in particular in such a way that the locking means 96 is arranged blocked in the vertical direction V and/or the detaching direction. In particular, rotating the at least one locking means 96 thus results in simultaneous positioning and locking of the washing device 86 . A sensor, preferably an inductive and/or optical sensor, preferably detects whether the at least one washing device 86 is locked and/or positioned. Such a sensor is distinguished, for example, by a compact design. For example, the at least one sensor is arranged in a bore at recess 98 . For example, the sensor can detect whether washing can be carried out or not. In addition, safety is increased since it can be recognized whether the washing device is installed correctly.

The at least one washing device 86 and in particular the at least one spray tube 106 are moistened with detergent and/or water by means of a media coupling, preferably on only one side of the washing device 86.

In a fastening method, the washing device 86 is fastened by means of the fastening device 90 . For this purpose, the washing device 86, in particular the at least one locking means 96 with the at least one locking element 97, is inserted and/or inserted and/or hung and/or laid in the recess 98. The at least one locking means 96 is inserted into the first part 103 of the recess 98 and/or the at least one locking element 97 is inserted into the second part 104 of the recess 98. The at least one locking element 97 is at least partially linearly guided through the second part 104 of the recess 98 . The at least one locking means 96 is pivoted by the handle 95, for example by 180°, and the at least one locking element 97 is moved linearly by the guide of the recess 98, as a result of which the at least one locking means 96 is set in a linear movement. In particular, the at least one locking means 96 is thereby transferred from the unlocked to the locked position. In particular, it is no longer possible to lift out the washing device 86 in the locked position because of the shape of the first part 103 of the recess 98 . In particular, the eccentrically arranged locking element 97 makes locking and positioning possible in one step. To remove it, a pivoting movement in the opposite direction is necessary. The at least one locking means 96 is held in position and locked by the at least one locking element 97 in the locked position. The at least one washing device 86 is converted from an unlocked state to a locked state by moving the at least one locking means 96 from an unlocked position to a locked position. The at least one locking means 96 is blocked in the transverse direction A by the arrangement of the recess 98 in two planes. Especially since the outer and/or second part 104 of the recess 98 is smaller than the first part 103 of the recess 98. The locking element 97 is held in position and guided by the second part 104 of the recess 98 and can preferably only move in one direction, preferably the vertical direction V. In this position, the washer 86 is located in the unlocked position. The at least one locking means 96 is moved partially linearly through the guide of the recess 98 by pivoting about the axis of rotation 101 of the at least one locking means 96 . By pivoting the at least one locking means 96 about the axis of rotation 101, the at least one locking element 97 is moved at least partially linearly through the guide of the recess 98. The linear movement of the at least one locking element 97 results in a linear movement and alignment of the at least one locking means 96 in addition to the pivoting and/or rotary movement. The at least one locking means 96 is held in place by the linear movement and the pivoting and/or rotary movement of the at least one locking means 96 transitioned from the unlocked position to the locked position. During the transfer from the unlocked position to the locked position, the at least one locking element 97 is transferred to a position in the vertical direction V above that of the axis of rotation 101 of the at least one locking means 96.

In particular, the at least one washing device 86 is mounted in a recess 98 on at least one printing unit frame 87 and/or on at least one coating unit frame 87 and/or on at least one side plate 88 and/or on at least one suspension 88 on the at least one printing unit frame 87 and/or attached to the at least one coating unit frame 87.

For locking, the at least one locking means 96 is rotated through an angle of between 120° and 240°, preferably 180°, preferably by means of the at least one handle 95 rotated. The formation of recess 98 moves the at least one locking element 97 in the vertical direction V and the at least one locking means 96, preferably due to the eccentric arrangement of the at least one locking element 97, preferably in one direction relative to the cylinder 33 to be cleaned; 34; 63, preferably in the transport direction T, shifted. In particular, the at least one locking means 96 is displaced in such a way that the at least one washing device 86 relative to the cylinder 33; 34; 63 is moved so that the washing device 86 to the cylinder 33; 34; 63 is employed. The at least one washing device 86 is attached by means of the at least one fastening device 90 relative to the at least one cylinder 33; 34; 63 can be aligned and locked and/or is aligned and locked. At the same time, the washing device 86 is locked so that it can no longer be lifted out through the formation of the recess 98 . Thus, the washing device 86 is positioned and locked in a simple manner. The precise positioning ensures that the at least one washing cloth 89 and/or the at least one cleaning cloth 89 is moistened.
