In Fig. 2 the finishing plant 3 shown in Fig. 1 is shown in more detail. The finishing unit 3 comprises a positioning device for optional Positioning at least the cylinder 7, the cylinder 7 being rotatable in the carrier 6 is mounted and together with the carrier 6 in different positions 54, 55, 62 forms adjustable unit 50. Unit 50 or the carrier 6 is by means of a gear 25 to 28 along a first Adjustable direction of movement and can be placed on a guide 18, 19. The unit seated on the guide 18, 19 is of the guide 18, 19 guided adjustable along a second direction of movement. The unit is 50 by means of the gear 25 to 28 from a maintenance and designated 54 Exchange position in the vertical direction in a designated 55 Rest position adjustable. In position 55, the unit 50 sits on the Guide 18, 19 and the cylinder 7 is a minimum distance from the Cylinder 4 carrying the printing material or the one lying thereon Substrate. The unit 50 is of the type as an adjustable support trained guide 18, 19 out of position 55 in a 62nd designated working position adjustable, in which the cylinder 7 with the Media-carrying cylinder 4 cooperates and the Coating liquid on the lying on this cylinder 4 Substrate. The adjustment of the unit 50 from the position 54 in the Position 55 takes place in almost or exactly vertical direction and from Position 55 in position 62 in a different from the vertical Direction. The carrier 6 consists of two cylinders 7 to 9 in the axial direction staggered side walls, between which the cylinders 7 to 9 are arranged and in which the cylinders 7 to 9 are rotatably mounted. The Guide 18, 19 comprises at least one rotatable about an eccentric bearing 36 Eccentric 19. Furthermore, the guide 18, 19 comprises at least one roller 18; 19. The at least one role 18; 19 can be the eccentric 19 itself. In the 2, the eccentric 19 is designed as a roller and an additional roller 18 on which the carrier 6 with one for Horizontal inclined guide surface 46 is seated. The eccentric 19 is in a pivot lever 39 pivotable about a pivot bearing 38. By pivoting the pivot lever 39, the unit 50 is out of the Position 55 adjustable to position 62 and back again. Through a Rotation of the eccentric 19 about the eccentric bearing 36 is the relative position of the Unit 50 for the bearing plate 39 designed as the pivot lever 39 adjustable and thus the distance of the cylinder 7 to the cylinder 4 in the Working position 62 adjustable or a substrate thickness adjustment possible. The eccentric bearing 36 consists of a bearing in the bearing plate 39 Pin and one seated on the pin and about its pin axis 40 by means of the lever 43 rotatable bushing. The pin or the pin axis 40 is eccentric to the center of the socket, which is rotatable on the axis of rotation 41 the bushing seated roller 19 corresponds.

In a modification, the pin and socket can be connected to one another in a rotationally fixed manner and the pin can be rotatably supported in the bearing plate 39. Are eccentric bearings in various designs and besides the described also functionally equivalent other designs can be used. The pivot axis 12 of the pivot bearing 11 is with the axis 41 and Eccentric axis 13 of the pivot bearing with the axis 40 and that Swivel bearing 11 adjusting lever 14 comparable to lever 43. The Function and purpose of the pivot bearing 11 will be discussed later explained. The eccentric 19 is by means of, for example, an electrical one Motor trained actuator 37 rotatable, the actuator 37 the Eccentric 19 rotated via the lever 43. The roller 18 is rotatable in one Side wall of the frame 53 stored. Preferably, the guide 18 comprises 19 two or more rollers 18 and two or more rollers 19, which each coaxially aligned and perpendicular to the image plane are arranged and on which the unit 50 is seated on both sides against tipping. On simultaneous rotation of the two rollers 19 is in this case on the two rollers 19 drivingly coupling synchronous shaft 45 possible, which is rotated by the actuator 37 via the lever 44. The carrier 6 has a surface 47 to 49 with two supporting the carrier 6 on the roller 19 Areas 47, 48 and one between the supporting areas 47, 48 lying contactless area 49 at a distance from the surface 47 to 49 Circumferential surface of the roller 19. Instead of the two at an angle to each other tapering straight support areas 47, 48 can also cover the entire area Surface 47 to 49 be curved concavely. The gear 25 to 28 is as a cylinder 7 or unit 50 in positions 54, 55 adjusting gear 25 and 28 comprising a traction mechanism 25 formed, the unit 50 on the traction device 25 hanging from the latter is held. The traction mechanism 25 to 28 is a paired shape Traction mechanism gear, the traction means 25 of at least two and for example three wheels 26 to 28 paired with the traction means 25 to be led. The gear 25 to 28 is specially designed as a chain gear with one formed as a traction link chain, the wheels 26 to 28 in the chain 25 engaging sprockets over which the chain 25 runs. The load on lifting unit 50 and from above on unit 50 advanced chain end 29 is attached to the carrier 6 unsprung, while the chain end 30, which is unloaded when it is lifted and is brought up from below connected to the carrier 6 by means of a spring 20 or attached to the latter is. The traction mechanism 25 to 28 is by the actuator 16, which can be an electric motor, for example, via the drive wheel 26 driven so that the carrier 6 together with the cylinder 7 by means of Traction mechanism 25 to 28 in a linear and approximately vertical Direction of movement can be raised and lowered to positions 54, 55 is. Similar to the guide 18, 19, the traction mechanism 25 to 28 is also in double version provided, with a vertical offset to the image plane another such traction mechanism 25 to 28 for lifting and lowering the unit 50 is arranged, which is essentially that shown Chain gear is the same. The tracked and when lifting the unit unloaded traction end of the further traction mechanism can be suspended from the unit 50 without suspension. The other not shown Traction mechanism also includes a drive wheel, which like that Drive wheel 26 is fixed on the synchronous shaft 35, so that both Traction mechanism drive coupled and working in parallel from Actuator 16 can be driven together. The carrier 6 is by means of Swivel lever 10 lockable to the frame 53, the locked Swivel lever 10 while maintaining the lock around the Swivel bearing 11 is pivotable. The pivot lever 10 and the carrier 6 are can be coupled to one another via a releasable positive connection 23, 24, the pivot lever 10 with the carrier 6 or one on this attached part is hooked. Instead of the hook-shaped design of the Swivel lever 10 can also with a possible reversal of the arrangement the carrier 6 a hook for catching the pivot lever 10 or one have this attached part. The positive form shown Connection 23, 24 consists of the bolt 23 fastened to the carrier 6, which when coupling the claw formed on the pivot lever 10 24 is partially included. The pivot bearing 11 is adjustable so that at the adjustment a pivot axis 12 of the pivot bearing 11 is shifted. For example, the pivot bearing 11 as a eccentric bearing 36 Moving the role 19 trained eccentric bearing. The Swivel bearing 11 is used as an actuator 15, with a Pressurized fluid, e.g. B. pneumatic cylinder against the Restoring effect of the spring 21 adjustable via the double lever 14. The Swing lever 10 is by means of a cam mechanism 17, 22, which a Link guide 17 and a part 22 guided therein, pivotable. The cam mechanism 17, 22 is a pivot lever 10 with the carrier 6 coupling or hooking pivoting movement of the pivot lever 10 around the pivot bearing 11 is formed to drive. The backdrop 17 is on Traction means 25 attached to the chain end 30 and the guided in the backdrop 17 Part 22 is designed as a pin attached to the pivot lever 10. The The guideway course of the backdrop 17 is angled and at least in sections not parallel to the first direction of movement of the unit 50 along the adjustment path between positions 54 and 55. Die Locking device 10 to 20, 22 to 24 can like the guide 18, 19 in double execution be provided on both sides of the unit 50.

The individual functions of the finishing plant 3 described above are again described below in connection with examples become. The operator of the printing press 1 places the unit 50 in the Finishing unit 3 in the easily accessible position 54 and connects the Unit 50 with the chain ends 29, 30. Then the actuator 16 activated so that the unit 50 is lowered from position 54 until the Unit 50 with the surfaces 46 to 48 sits on the rollers 18, 19. While when lowering, the unit 50 hangs practically freely on the traction means 25 and can swing a little to the right and left in the image plane. The rollers 33 are offset in the horizontal direction from the center of mass of the unit 50 attacking chain and unit 50 slightly tilted in the image plane to the Walls 63 and can in another embodiment with in Center of gravity on attacking chain and unit hanging quietly on the chain 50 have a small distance from the walls 63. During the When the unit 50 is lowered, the groove of the link 17 is moved over the pin 22 pushed into the wedge-shaped end of the groove that is open at the bottom Backdrop 17 is introduced. Upon further movement of the traction means 25 pulled backdrop 17 is an adjustment of the pivot lever 10 from a pivot lever position, not shown, in which the claw 24 the Bolt 23 not yet included (unlocked) in that shown in Fig. 2 Swing lever position in which the claw 24 and the bolt 23 in Form-fit (locked) with each other. After unit 50 has been touched down on the guide 18, 19, the traction means 25 tensions the spring 20, the span is used to the pivot lever 10 in its locked position swing. This swiveling process is finished when the hook-shaped End of the pivot lever 10 encloses the pin 23 and the pin 22 in Fig. 2 has reached the rest position. The attached to the chain 25 Link 17 is just as the chain end 30 resilient on the unit 50 attached, so that the backdrop 17 in tensioning the spring 20 in Direction of travel corresponding to the travel a piece from unit 50 is pulled away. The swivel lever 10 has already been locked with the carrier 6 and the secure seating of the unit 50 on the guide 18, 19th is subsequently effected via the actuator 15 by deactivating it and for example, the actuator 15 designed as a pneumatic cylinder is vented is, so that the spring 21, the eccentric adjustment of the pivot bearing 11th resets. By adjusting the pivot bearing 11 Swivel lever 10 minimally in the direction of the swivel bearing 11 or downwards pulled so that the lock is secured by the top Inner surface of the claw 24 firmly pressed onto the peripheral surface of the bolt 23 becomes, as shown in Fig. 2. The locking can be done by pressing the inner surface on the bolts 23 are secured in a non-positive or positive manner. A non-positive securing is given when the inner surface is on top is contoured in a straight line, so that when the pivot lever 10 is pivoted based on Fig. 2 to the left between the bolt 23 and the surface pressure or friction acting on this pressed-on inner surface prevents the claw 24 from sliding off the bolt 23 and causes the Bolt 23 and thus the unit 50 with the pivoted pivot lever 10 remains coupled. A form-fit securing exists if the top inner surface formed as a downwardly open recess which, when the pivot lever 10 is moved downward, the pin 23 encompasses both sides from above. For example, the inner surface can be a Bolt diameter matched concave curvature, which around the half pin circumference facing upwards, so that the pin 23rd both when pivoting the pivot lever 10 to the left and to right is secured against slipping out of the claw 24.

Due to the high translation of the eccentric bearing 11 can on as one a spring rod acting compression spring trained spring 21 a high Clamping force for fixing the pivot lever 10 on the guide 18, 19th held unit 50 are applied. When the unit 50 is securely fixed the actuator 16 can be deactivated. By swiveling the bearing plate 39 around the swivel bearing 38 is the one seated on the guide 18, 19 Unit 50 guided by the guide 18, 19 along the second Direction of movement towards the impression cylinder 4 from position 55 (Rest position) in position 62 (working position). This adjustment is in the following based on the usual designation for printing units also called pressure circuit. The distance of the peripheral surface of the in position 62 application cylinder 7 to the peripheral surface of the Counter-pressure cylinder 4 or the pressure of the application cylinder 7 against the to be coated on the impression cylinder 4 Substrate sheet is possible by rotating the eccentric bearing 36, where the center of the roll 19 and thus the center of the roll 19 supporting unit 50 is shifted. This by means of the as electrical Stepper motor trained actuator 37 very sensitive Adjustment is also referred to below as pressure provision. Both at the pressure circuit as well as the pressure supply, the unit 50 by an adjustable part of the guide 18, 19, namely the roller 19, relocated and almost tangential along an ideal circular path, which the hook-shaped end of the pivot lever 10 around the pivot bearing 11 at Panning describes, postponed. An insignificant relative movement of the Unit 50 in the pressure circuit and pressure supply radial to Swivel bearing 11 is secured by the readjustment of the spring 21 compensated. Due to the large length of the pivot lever 10 or the large The spring 21 becomes the distance from the locking point to the pivot bearing 11 when moving the unit 50 on the guide 18, 19 only slightly further stretched or relaxed after the direction of displacement. The pressure circuit and provision of pressure drives, z. B. the actuator 37 must in addition to the actuating forces only the one caused by the preload Overcome rolling friction in the contact surfaces of the guide 18, 19. The Unlock and remove the unit 50 to the opposite Way practically in reverse order. To unlock the Pneumatic cylinder 15 is pressurized with air and is via the eccentric bearing 11 the lock 23, 24 force-free. The motor 16 then drives the chain 25 on and relaxes the spring 20 on which the backdrop 17 hangs. This will the pivot lever 10 from its position shown, on the image plane related pivoted away to the left so that the bolt 23 is free. The the Chain 25 driving motor 16 in the opposite direction causes unit 50 to lift off guide 18, 19 and one Adjustment back along the first direction of movement into the easily accessible Maintenance position 54, in which the stop 31 of the unit 50 stops 32 of the frame 53 rests and from which the operator unites the unit 50 can see the finishing plant 3. Instead of the pneumatic cylinder 15 can open the lock in a further development of the device chain movement can also be used.

If the cylinder 7 with the substrate 4 works together and z. B. on one lying on the cylinder 4 Cylinder applies a coating liquid, the cylinder 7 through the gear coupling via the gears 56, 57 from Drive 59 driven in coordination with cylinder 4. The drive 58 is used Angle adjustment of the cylinder 7 and drives the cylinder 7 Maintenance work, e.g. B. in its cleaning and any Cylinder lift change, where the unit 50 and thus the cylinder 7 itself is in the easily accessible maintenance position 54.

The chronological order of the individual process steps during the shutdown of the in Fig. 2nd The unit 50 shown from position 54 to position 55 is shown below explained using program levels 64 to 75 as an example. The Program level 64 includes the start of the program, whereby the Shutdown of unit 50 from position 54 to position 55 begins. Subsequent program levels 65 to 69 are processed in parallel, whereby in program stage 65, the phase position of the impression cylinder 4 by means of of the main drive 59 of the printing press 1, which drives this in rotation is set and fixed. In program stage 66, the phase position of the Order cylinder 7 by means of the integrated in the unit 50 Order cylinder 7 rotary drive 58, which together with the unit 50 is movable, also adjusted and positioned. In the Program level 67 is a circumferential register adjustment of the Order cylinder 7, z. B. a paint form located on this is aligned in register. In program stage 68, unit 50 from the maintenance position 54 into a position between this and the rest position 55 lying intermediate position (not shown in FIG. 2) lowered. In this intermediate position is a drive connected to the cylinder 7 and Z. B. on the pin sitting gear 56 not yet with drive connected to the cylinder 4 and for example on the latter Pin-seated gear 57 is engaged and the cylinder 7 is not by one secured securing device shown against rotation, one for finding the teeth of the gears 56, 57 if necessary, very small torsional backlash of the cylinder 7 still can be present. In program level 69, in addition to those in the Program levels 65 to 68 individual functions 1 to 4 more Individual functions 5 to n may be provided. In program stage 70 there is a Query whether the individual functions 1 to n or the program levels 65 to 69 Are completed. The program stage 71 represents a loop, which from The program is run through if the condition according to program level 70 is not yet fulfilled. When all processes 1 to n have been completed, in the Program stage 72 a disengagement of the cylinder drive 58. Die drive connection of the application cylinder 7 with the drive 58, z. B. an electric motor, is released by releasing the clutch 60. In the subsequent program stage 73, the unit 50 from the intermediate position lowered into the rest position 55 shown in FIG. 2. Parallel to Program level 73 may not be required in every case Fine positioning of the tooth engagement of the teeth of the application cylinder 7 coaxially arranged gear 56 to the teeth of the Printing medium-carrying cylinder 4 coaxially arranged gear 57 and the gear 56 with the gear 57 by lowering the Unit 50 engaged. The program ends at program level 75. In the event that between the drive 58 and the cylinder 7 or the gear 56 a freewheel with a low freewheel clearance is installed, the uncoupling can of the drive 58 from the cylinder 7 also at a later time take place when the teeth of the gear wheels 56, 57 are already in engagement with one another are brought. The gears 56, 57 are both in the rest position 55 and also engaged in the working position 62. The adjustment path of the Unit 50 from its working position 62 to the rest position 55 is not so large that the gear teeth come out of engagement. If the cylinder 7 with the printing medium-carrying cylinder 4 cooperates and z. B. on one on the cylinder 4 resting sheet of printing material Applying coating liquid, the cylinder 7 through the transmission coupling via the gears 56, 57 from the drive 59 in Voting for cylinder 4 driven. The drive 58 is used described angular adjustment of the cylinder 7 and drives the cylinder 7 Maintenance work, e.g. B. in its cleaning and any Cylinder lift change, on which the unit 50 and thus the cylinder 7 is in the easily accessible maintenance position 54. The Cylinder lift can e.g. B. if the finishing unit 3 is a coating unit, a Lacquer plate. In the event that the in-line operated finishing plant 3 a Deforming substrate sheet, e.g. B. impressing or punching processing station, the cylinder lift can be used corresponding tools. With one as numbering or Impression unit trained finishing unit 3, the cylinder lift can Printing form. The cylinder lift change can be automatic or done semi-automatically and cleaning the cylinder 7, z. B. washing of the cylinder lift, can be done manually or using a cleaning device automated. Both when changing cylinder lifts and when The cylinder 7 and any further in the carrier 6 are cleaned stored and the unit 50 associated cylinders 8, 9 to be cleaned by the Drive 58 driven.

FIG. 4 shows a time diagram which shows the time course of the various to be carried out during the operation of the printing press 1 and shows time-coordinated process steps a to h. The Process steps a to h are considered the dark areas of the horizontal timelines identified. While on the Ordinate axis of the diagram, the process steps are therefore plotted, the abscissa axis is divided into eleven time units of equal size, the a time period that really corresponds to a time unit z. B. ten seconds however, may be for the explanation of the sequence of each Procedural steps is irrelevant. Process steps a to d correspond correspond to program levels 65 to 68 and process steps e to g program levels 72 to 74 and method steps h represent a Summary of program levels 64 and 75. It is shown that the Process steps a to d and also process steps f and g each start at the same time. All process steps a to d are carried out via the Time units 2 to 5 carried out in parallel or simultaneously. Under the Term at least partially at the same time is intended to overlap Process steps are understood, which are also assumed to be in the Steps b and c would be given if step b with End of time unit 4 would be completed and method step c only with Beginning of time unit 4 would begin. In this exemplary case would process steps b and c at least during the period 4 be carried out at the same time. The timing diagram also shows that the process steps e, f, g after the completion of process steps a to d and process steps f and g after the completion of process step e kick off. Process steps f and g are carried out at exactly the same time, d. H. these process steps do not only overlap in time but also begin and end at the same time.

5, the essential parts of a modified embodiment of the in Fig. 2 shown device. Instead of that shown in Fig. 2 Cam gear for pivoting the pivot lever 10 is in the modified embodiment according to FIG. 5, the swivel lever 10 by means of a lever gear pivoted. Except for the modified one Embodiment parts with the reference numerals 14, 15, 17, 21 and 22 (FIG. 2) comprises the device shown in FIG. 5 in the same arrangement all parts shown in Fig. 2, even if for reasons of a better clarity are not completely shown in FIG. 5. at the parts from FIG. 2 which are shown repeatedly in FIG. 5 are the Reference numerals have been retained.

The pivoting of the pivot lever 10 opposite to Clockwise rotation takes place against the effect of a frame-supported and on a rod 82 articulated to the pivot lever 10 seated coil spring 83. The pivot lever 10 from the carrier 6th unlocking pivoting movement is counterclockwise driven by the actuator 85 and takes place via an eccentric bearing 11 understand lever 78, which thereby on a fixed to the frame joint 80th pivots lever 77, which in turn presses on a pivot lever 10 attached stop 81 presses. The actuator 85 is as a Working cylinder can be pressurized with air, which when entering Piston rod first causes an adjustment of the eccentric bearing 11, so that the pivot lever 10 slightly upwards in its longitudinal direction is shifted, and which subsequently over the parts 78, 79 and 81 the Swivel lever 10 against the action of a spring 83 around the bearing 11 pivots so that the pivot lever 10 and the carrier 6 are unhooked. The Lever 77 is designed as a one-armed lever, which at a lever end in Joint 80 is loosely hanging hanging down and on its long The other lever end forming the lever arm is the roller 79 attached to the lever 78 presses so that a short lever arm of the lever 77 resulting between the lever region of the lever 77 lying at the two lever ends of the lever 77 strikes against the stop 81 and via this on the swivel lever 10 attached stop 81 adjusts the pivot lever 10. The spring 83 is as a resilient coil spring wound around a rod 82 educated. The rod 82 is in the frame via a swivel and push joint 88 53 mounted and articulated to the pivot lever 10. The from Carrier 6 decoupled pivot lever 10 is shown in phantom in FIG. 5. The pivoting lever 10 and carrier 6 are locked on opposite way. When switching the Pressurized air of the double-acting working cylinder 85 acts Spring force of the spring 83 supported on the frame via the frame 53 both pivotable as well as slidably mounted rod 82 on the pivot lever 10, so that it is pivoted clockwise and against the on the carrier 6 attached bolts 23 strikes. The movement of the pivot lever 10 in Clockwise rotation is damped by the damper 84, so that The pivot lever 10 strikes the bolt 23 very gently. The Damper 84 is designed as a piston damper, the piston rod through the rod 82 is formed. One the pivot lever 10 in its Longitudinal downward adjustment of the eccentric bearing 11 causes that the inner surface of the claw 24 is pressed onto the top of the bolt 23 is and is by a piston rod of the working cylinder 85th exiting opposite with respect to unlocking Compressed air pressure on the working cylinder 85 can be effected. A sensor 87 serves the electronic control device 61 of the printing press 1 the current coupling state of the pivot lever 10 to the carrier 6 signal. The drive 59 (FIG. 2) is controlled by the control device 61 deactivated, e.g. B. by the control device 61 the drive 59 supply circuit breaks when the pivot lever 10 and the Carrier 6 not properly coupled when unit 50 is shut down are. The sensor 87 is attached to the carrier 6 and as an electrical Microswitch formed, which can be actuated by the pivot lever 10 and whose correct locking is felt with the carrier. A guide 86 is as a screw screwed into the frame 53 formed in the head, which in an elongated hole of the pivot lever 10 is guided and the pivot lever 10 secures against tilting perpendicular to the image plane.
