Definitions
- the invention relates to a sheet-fed rotary printing machine with an electrode unit according to the preamble of claim 1.
- sheets are coated with a coating agent, such as printing ink, in a contact zone between a transfer cylinder and an impression cylinder.
- a coating agent such as printing ink
- Other coating units are also known, such as flexo coating units, in which the sheets interact directly with a forme cylinder and an impression cylinder. These are used, for example, as printing units or as varnish units.
- the sheets may stick to the transfer cylinder or the forme cylinder. While the movement of the leading edge of the sheet is largely determined by the grippers of the impression cylinder, the sheet in the rear area can stretch considerably and/or detach from the impression cylinder. As soon as the trailing edge of the respective sheet leaves the contact zone, this sheet can suddenly relax.
- the trailing edge of the sheet can even temporarily overtake its target position on the cylinder circumference. This can have a negative impact on further sheet transport. However, it is particularly problematic if an inspection system is installed, past which the sheets are transported on the impression cylinder in order to be inspected. The stretching and the abrupt change in the position of the sheet make evaluation difficult or impossible, particularly in the rear area of the respective sheet.
- US 3 346253 A discloses a sheet-fed rotary printing press which has an electrode unit in the area after the contact zone between the transfer cylinder and the impression cylinder, wherein this electrode unit can be adjusted in its position by means of adjusting screws and should preferably be arranged approximately two inches away from the impression cylinder.
- DE 102008 001 165 A1 discloses a sheet-fed rotary printing press in which sheets are electrostatically charged before the contact zone between the transfer cylinder and the impression cylinder in order to facilitate inspection after this contact zone.
- DE 102010 003 046 A1 discloses a sheet-fed rotary printing press which has a blowing device in the area after the contact zone between the transfer cylinder and the impression cylinder in order to facilitate inspection after this contact zone.
- EP 2 982 510 A1 discloses a sheet-fed rotary printing press which has an inkjet module which is arranged in the region after the contact zone between the transfer cylinder and the impression cylinder and which has an electrostatic sheet guiding device within a housing of this module in order to facilitate inkjet printing and inspection within this module.
- DE 100 33 839 A1 discloses a sheet-fed printing machine which can have a drying device at different locations, whereby To assist in drying, an electrode is arranged whose distance to a counter-pressure cylinder can be changed so that a collision with a gripper system can be prevented.
- DE 10041 934 A1 discloses a sheet-fed printing machine which has a drying device, wherein an electrode is arranged to assist the drying process, the distance between the electrode and an impression cylinder being a few millimeters.

- a sheet-fed rotary printing press preferably has at least one rotary transport body for transporting sheets.
- the sheet-fed rotary printing press preferably has at least one coating unit, which is designed, for example, as a printing unit or as a varnishing unit.

- the sheet-fed rotary printing press preferably has at least one charging device for electrostatically fixing sheets to the rotary transport body.
- the coating unit designed, for example, as a printing unit or varnishing unit, preferably has at least one Charging device for electrostatically fixing sheets to the impression cylinder, which has at least one electrode unit aligned and/or alignable with a circumferential surface of the impression cylinder.
- the sheet-fed rotary printing press is preferably characterized in that the at least one electrode unit is arranged so as to be movable between at least two layers.
- one of the at least two layers is a working position and/or a particularly other one of the at least two layers is a storage position.
- a very close arrangement of the electrode unit can then be combined for a particularly good working result with the ability to be stored for particularly easy accessibility.
- the charging device therefore preferably has at least one electrode unit with at least one electrode, which is arranged so as to be movable between at least two layers and is aligned and/or alignable with a lateral surface of the rotary transport body.
- a charge core zone is preferably a region of a cylinder surface enveloping a cylinder barrel of the impression cylinder that is closest to the at least one electrode unit.
- the charge core zone is preferably arranged after the contact zone and before a transfer point leading away from the impression cylinder, as seen in the direction of rotation of the impression cylinder.

Even in the event of an abrupt relaxation of the part of the sheet that has not yet been fixed, possible corresponding problems are thereby minimized.
- the electrostatic forces that occur are used to lay the respective sheet flat against the impression cylinder and/or to generate a friction force that prevents or significantly slows down a relaxation movement of the respective sheet.

- this return force F is a force F whose direction has at least one component that is parallel to a direction pointing from the at least one electrode unit 88 to the contact zone.
- the at least one second holding element 103 only allows a movement of the at least one electrode unit 88 out of the storage position caused by such a return force F if this return force exceeds a second threshold value.
- This second threshold value is preferably a fixed property of the at least one second holding element 103.
- the at least one second holding element 103 is designed as a magnetic holding element 103. Then it only prevents unwanted movements of the at least one electrode unit 88 out of the storage position and/or towards the working position.
- the at least one second holding element 103 is designed as a mechanical locking element 103.
- it then has at least one spring element which, for example, presses a stop body into a position which prevents movement of the at least one electrode unit 88 if the return forces F are too low. This therefore also prevents unwanted movements of the at least one electrode unit 88 into the storage position.
- the at least one electrode unit 88 is preferably pivotally mounted, in particular about an electrode pivot axis E and/or the at least one electrode unit 88 is designed to be movable between the working position and the storage position by means of a pivoting movement.
- the at least one electrode unit 88 preferably has an active side 107 which, when the electrode unit 88 is arranged in the working position, is arranged facing the rotary transport body 34; 61 and which, when the electrode unit 88 is arranged in the storage position, is arranged facing away from the rotary transport body 34; 61.
- the at least one electrode 93 is enclosed in a housing 119 of the electrode unit 88 and is preferably only accessible from one direction from the outside. This direction then defines the active side 107.
- the at least one electrode 93 preferably has areas with particularly small radii of curvature on its surface, which are more preferably designed as needles 108. These needles 108 are preferably arranged on the active side 107. In these areas, especially needles 108, a corresponding electric field strength is particularly high and allows a particularly effective charging of the sheets B.
- the actuator 106 of the actuator 104 is connected in an articulated manner to the at least one electrode unit 88.
- a corresponding first joint 121 is preferably arranged at a distance from the pivot axis 114 and more preferably closer to the active side 107 of the electrode unit 88 than the pivot axis 114.
- the At least one actuator 106 of the at least one actuating device 104 is preferably designed as a pneumatic cylinder 106 and/or as a hydraulic cylinder 106 and/or as an electric drive 106 and/or as a linear drive 106.
- the actuator 106 is preferably connected to a bearing element 111 via a second joint 122.
- the at least one actuator 106 is preferably arranged in such an articulated manner with the at least one electrode unit 88 that, at least when the electrode unit is arranged in the working position, a first joint angle 123 deviates from a right angle (90°) by at most 45°, more preferably at most 30° and even more preferably at most 20°, wherein this joint angle 123 is preferably the angle between two straight lines, one of which intersects both the electrode pivot axis E and a pivot axis of the first joint 121 and the other of which intersects both the pivot axis of the first joint 121 and the pivot axis of the second joint 122.
- the bearing element 111 can be arranged in a fixed position. However, the bearing element is preferably designed to be movable.
- the bearing element 111 is designed as a sliding block 111 that can be moved in a guide 109.
- the at least one actuator 106 is therefore preferably arranged in an articulated manner on a sliding block 111 that is arranged to be movable along a guide 109.
- the sliding block 111 is preferably held in a first holding position by means of the at least one first holding element 102.
- the sliding block 111 is preferably held in a second holding position by means of the at least one second holding element 103.
- the actuating device 104 can be switched between three provided configurations.
- a first of these configurations is an operating configuration.
- a second of these configurations is a maintenance configuration.
- a third of these configurations is an alternative configuration. (This is also shown in Fig. 14, for example.)
- the actuating device 104 is preferably arranged in the operating configuration, in particular during a planned printing operation of the sheet-fed rotary printing press.
- the at least one electrode unit 88 is arranged in its working position and the actuator 106 is preferably arranged in a retracted state and the at least one sliding block 111 is preferably arranged in its first holding position by means of the at least one first holding element 102. Due to the inherently rigid actuator 106 and the effect of the first holding element 102, the electrode unit 88 is held firmly in its working position under normal operating conditions.
- the actuator 106 can be extended in particular for maintenance purposes. In doing so, the actuator 106 is supported in particular via the sliding block 111 on a stationary component. This pivots the electrode unit 88 into the storage position. The active side 107 of the electrode unit 88 can thus be made accessible, in particular if a corresponding protection of the housing of the sheet-fed rotary printing press is opened.
- the actuating device 104 is then in its maintenance configuration.
- the actuator 106 can then be retracted again.
- the first holding element 102 is designed such that the forces occurring during operation cannot move the sliding block 111 and it remains in its position. Contracting the actuator 106 then causes a pivoting movement of the electrode unit 88 back into the working position.
- the actuating device 104 is then back in its operating configuration.
- the electrode unit 88 In its working position, the electrode unit 88 is arranged with a relatively small distance to the impression cylinder 34; 61. If material of too great a thickness is carried along by the impression cylinder 34; 61, this could damage the electrode unit 88 if it remained in place.
- the adjusting device 104 is therefore designed so that designed to allow passive deflection of the electrode unit 88. As soon as a force is exerted on the electrode unit 88 such that an deflection force K of a corresponding magnitude is exerted, the electrode unit 88 performs a pivoting movement into the storage position. To do this, it pulls on the actuator 106, which transfers this pulling movement to the sliding block 111.
- the actuating drive 106 In order to return the actuating device 104 to its operating configuration and thus the electrode unit 88 to its working position, the actuating drive 106 is first extended. The end of the actuating drive 106 arranged on the electrode unit 88 can no longer move away and the force exerted by the actuating drive 106 therefore moves the sliding block 111 along the guide 109 into the first holding position, overcoming the second holding device 103 and possibly also the first holding device 120. The actuating device 104 is then initially in its maintenance configuration and can be returned from this to the operating configuration as previously described.
- At least one position sensor 124 is arranged. This position sensor 124 serves in particular to check whether the electrode unit 88 is in its working position or not.
- the at least one position sensor 124 is designed as a proximity switch 124. Any type of proximity switch 124 is possible, in particular inductive, capacitive, magnetic and optical proximity switches as well as light barriers and/or ultrasonic sensors.
- a test body 126 is arranged, the detection of which by the position sensor 124 provides information about the position of the electrode unit 88.
- the test body 126 is preferably arranged so as to be adjustable and is designed, for example, as a threaded pin 126.
- the at least one Position sensor 124 is connected to the higher-level machine control system via circuitry. If position sensor 124 detects an evasive movement of the electrode unit 88 when the sheet travel is activated, the machine control system can cause the sheet-fed rotary printing press to stop.
