Because the second pressure plate 101 especially flexible along its length L, it bulges in its between the angle 161 and the stop 162 clamped state. The slider 159 of the printing form holder 158 is preferably linear parallel to the support 154 movable and preferably has two stable operating positions, namely a stable operating position in the retracted, the second pressure plate 101 releasing state and in the extended, ie the second pressure plate 101 clamping state.

In the 9 is another shaft 141 pictured, the inclusion of the plate cylinder 07 removed printing plates 101 serves. This shaft 141 has a z. B. inclined edition 172 on which as well as the edition 154 in the shaft 143 for providing on the plate cylinder 07 to be mounted printing plates 101 preferably not over the entire surface, but in the form of parallel strips 172 or slide rails 172 is trained. In the in the 9 The example shown is the shaft 141 for receiving the plate cylinder 07 removed printing plates 101 below the shaft 143 for providing on the plate cylinder 07 to be mounted printing plates 101 , which is a preferred but not a compelling arrangement.

A preferred embodiment of the shaft 141 provides that in the shaft 141 in the axial direction of the printing cylinder 07 next to each other at least two printing plates 101 are storable. This embodiment allows a particularly fast removal of printing plates 101 especially if on the plate cylinder 07 in its axial direction at least two printing plates 101 can be arranged, because several printing plates 101 at the same time from the plate cylinder 07 can be removed.

At the plate cylinder 07 facing side, the shaft 141 for receiving the plate cylinder 07 removed printing plates 101 at least in the plate cylinder 07 employed operating state a near the lateral surface 107 of the printing cylinder 07 arranged guide element 173 on which z. B. in the form of a baffle 173 , a wedge 173 or a rolling element 173 , z. B. a role 173 is trained and has the task, the trailing end 104 one from the plate cylinder 07 to be removed printing plate 101 in the shaft 141 respectively. A distance a173 of the guide element 173 from the lateral surface 107 of the printing cylinder 07 is preferably not much larger than the length of the folded Einhänlegeels 114 on the slow down finish 104 the printing plate 101 , On the guide element 173 can be a sensor 191 be attached, either in contact with the plate cylinder 07 to be removed printing plate 101 or advantageously contactless, e.g. B. inductive, checks if the suspension leg 114 at the trailing end 104 the one from the plate cylinder 07 to be removed printing plate 101 after pressing the button in the channel 108 of the printing cylinder 07 arranged holding means 121 actually solved.

In a preferred embodiment, the suspension leg sets 114 at the trailing end 104 the one from the plate cylinder 07 to be removed printing plate 101 after passing the guide element 173 preferably on one of the guide element 173 spaced apart first ramp 174 on before he restarts the edition 172 in the shaft 141 achieved, with the first ramp 174 in the direction of the edition 172 initially rises and after a peak 176 for circulation 172 back down again. The first ramp 174 is preferably rigid with the support 172 connected. In progress of introduction of the plate cylinder 07 to be removed printing plate 101 in the shaft 141 meets her hanging leg 114 at the trailing end 104 on a second ramp 177 whose flank after its peak 178 ie on the plate cylinder 07 opposite side, preferably abruptly steep to support 172 falls off. In the direction in which the pressure plate 101 in the shaft 141 is introduced a short distance behind the summit point 178 one with the second ramp 177 rigidly connected stop 179 arranged on the suspension leg 114 at the trailing end 104 the printing plate 101 strikes. If the suspension leg 114 at the trailing end 104 the printing plate 101 to the stop 179 strikes, he preferably engages behind the second ramp 177 by the suspension leg 114 engages in the gap formed by said distance.

The second ramp 177 and the stop associated with it 179 are through a conveyor 181 linear and parallel to the support 172 movable to that of the plate cylinder 07 to be removed printing plate 101 completely in the shaft 141 to carry in. The conveyor 181 in particular, along with the steep flank on the second ramp 177 for the folded suspension leg 114 at the trailing end 104 the printing plate 101 one the pressure plate 101 in the shaft 141 promotional entrainment means forms, for. B. as a belt drive 181 or as a linear actuator 181 , preferably as a pneumatic linear drive 181 , in particular as a rodless, double-acting linear drive 181 educated.

On the plate cylinder 07 opposite side is in the shaft 141 a lift 182 , in particular a printing form lifter 182 arranged, wherein the printing form lifter 182 for example, a preferably perpendicular to the edition 172 movable piston 183 has, at the end of a z. B. L-shaped, in particular U-shaped lifting arm 184 is arranged, wherein the folded suspension leg 114 at the trailing end 104 the printing plate 101 on the lifting arm 184 is set up or comprehensively adjusted. The printing form lifter 182 preferably has two stable operating positions, namely a stable operating position with retracted piston 183 in which the lifting arm 184 below the through the pad 172 defined levels, and another stable operating position with extended piston 183 in which the lifting arm 184 the one from the plate cylinder 07 removed printing plate 101 from the edition 172 raising. The printing form lifter 182 In doing so, it executes a stroke s182, which is greater than the length of the folded-in suspension handle 114 at the trailing end 104 the printing plate 101 , Preferably, the stroke s182 has a value between the single and double the length of the Einhänlegeels 114 on. The printing form lifter 182 thus raises one from the plate cylinder 07 removed printing plate 101 from a preliminary first storage position to a final second storage position.

Above the printing form lifter 182 , in particular above its lifting arm 184 is a preferably about a substantially parallel to the width B of the printing plate 101 extending pivot axis pivoting fuse element 186 arranged, z. B. in the form of a strip-shaped flap 186 whose lower edge is at a distance a186 from the lifting arm 184 is located, wherein the distance a186 is preferably dimensioned smaller than the length of the folded Einhänlegeels 114 at the trailing end 104 the printing plate 101 , In the 9 indicates a direction arrow the pivoting of the fuse element 186 at. The fuse element 186 secures one from the printing form lifter 182 raised pressure plate 101 against unintentional slipping in the shaft 141 or a removal from the shaft 141 , So an operator has the fuse element 186 first to pivot before the raised pressure plate 101 from the shaft 141 can be removed.

The 10 to 14 show by way of example several stages of the procedure for changing printing plates 101 on a plate cylinder 07 , It is initially assumed that in the upper shaft 143 to provide new ones on the plate cylinder 07 to be mounted pressure plates 101 two printing plates 101 are arranged on the plate cylinder 07 along the circumference of two printing plates 101 are hung up and that the lower shaft 141 for receiving the plate cylinder 07 removed printing plates 101 empty, ie free from printing plates 101 is, cf. 10 , The plate cylinder 07 turns the opening 109 a channel 108 , in which the suspension leg 114 at the trailing end 104 the one from the plate cylinder 07 to be removed printing plate 101 from a holding means 121 held in a first position, which is below the lower shaft 141 belonging guide element 173 located. The pressing element 124 becomes on the plate cylinder 07 employed ( 10 ).

Then the holding means 121 against the force of a spring element 122 pivoted, causing the suspension leg 114 at the trailing end 104 the printing plate 101 due to its elastic residual stress from the opening 109 snaps and on the guide element 173 strikes. The employed pressure element 124 secures the pressure plate 101 against a further release of the lateral surface 107 of the plate cylinder 07 ,

The plate cylinder 07 then turns counter to its production direction P and pushes the trailing end 104 the printing plate 101 in the shaft 141 , At the introduction of the printing plate 101 in the shaft 141 slides the suspension leg 114 at the trailing end 104 this printing plate 101 first on the guide element 173 along and then turns on the to the shaft 141 belonging first ramp 174 on. The suspension leg 114 slides the ramp 174 up to over the summit 176 and then reaches the circulation 172 , While the pressing element 124 continue on the plate cylinder 07 is employed, the pressure plate 101 by the rotation of the plate cylinder 07 contrary to its production direction P further into the shaft 142 inserted. In doing so, you overcome the hanging leg 114 at the trailing end 104 also with the conveyor 181 connected second ramp 177 and bumps into the second ramp 177 connected stop 179 ,

Now the pressure element 124 from the plate cylinder 07 switched off. Through the bump of the suspension gadget 114 of the trailing end 104 at the stop 179 releases the form-fitting at the front edge 116 the opening 109 hinged folded legs 113 at the leading end 103 the printing plate 101 out of the opening 109 , The printing plate 101 is now with its leading end 103 free on the lateral surface 107 of the printing cylinder 07 on. The plate cylinder 07 has from loosening the suspension gadget 114 at the trailing end 104 less than half a turn done so far. The folded suspension leg 114 at the trailing end 104 has between the second ramp 177 and the stop 179 hooked. The second ramp 177 and the stop 179 connected conveyor 181 can the pressure plate 101 now completely in the shaft 141 move in, cf. 11 ,

The printing plate 101 is now from the plate cylinder 07 removed and is located in the slot L its length 141 , Your suspension leg 114 at the trailing end 104 is on the summit 178 the second ramp 177 on while your fore end 103 on the summit 176 the first ramp 174 rests, whereby at least the suspension leg 113 at the leading end 103 preferably free hanging. The storage of the printing plate 101 in the shaft 141 is therefore preferably by a support at two points, namely on the summit points 176 ; 178 the two ramps 174 ; 177 ,

The z. B. pneumatically actuated Druckformheber 182 now lift the one into the shaft 141 retracted pressure plate 101 at its trailing end 104 until just below the fuse element 186 on, with the suspension leg 114 on the with the printing form lifter 182 connected lifting arm 184 gets up, cf. 12 ,

The close to the plate cylinder 07 arranged alignment device 151 pivots with their previously preferably horizontally oriented diametral stops 152 ; 153 preferably by 90 ° in a vertical position, so that on the width B of the plate cylinder 07 to be mounted pressure plate 101 coordinated stop 152 ; 153 in one by the edition 154 in the shaft 143 defined transport plane for those on the plate cylinder 07 to be mounted pressure plate 101 dips and the on the plate cylinder 07 to be mounted pressure plate 101 during their transport out of the shaft 143 at the stop 152 ; 153 page register moderate to the plate cylinder 07 is aligned.

For mounting a pressure plate to be mounted 101 on the plate cylinder 07 this initially rotates further counter to its production direction P in a receiving position. The on the plate cylinder 07 to be mounted first pressure plate 101 stands with her suspension leg 114 at its trailing end 104 on with a conveyor 157 connected stop 156 at. The conveyor 157 is put into operation, so the stop 156 in a preferably tangential to the plate cylinder 07 directed movement the first pressure plate 101 far from the shaft 143 promoted until its leading end 103 that on the plate cylinder 07 employed pressing element 124 touched and the at this leading end 103 folded suspension legs 113 between in the direction of production P of the printing cylinder 07 rear edge 117 the opening 109 and the point of contact 188 of the pressure element 124 on the plate cylinder 07 gets up, cf. 13 ,

The plate cylinder 07 now changes its direction of rotation and begins to rotate in its production direction P, causing the on the plate cylinder 07 mounted suspension leg 113 at the leading end 103 the printing plate 101 in the opening 109 slips and fits snugly on the front edge 116 the opening 109 hooked. By the further rotation of the plate cylinder 07 in its production direction P, the printing plate 101 completely out of the shaft 143 carried out and on the plate cylinder 07 reared. During winding, the pressure plate becomes 101 through the on the plate cylinder 07 employed pressing element 124 on the plate cylinder 07 rolled on. After half a revolution of the printing cylinder 07 in his direction of production P presses the pressure element 124 the folded suspension leg 114 at the trailing end 104 the printing plate 101 in the opening 109 , The holding means 121 in the to this opening 109 belonging channel 108 was solved and is then brought into the operating position in which it in the opening 109 inserted suspension leg 114 at the trailing end 104 the printing plate 101 z. B. fixed by a clamp. The conveyor 157 drives the stop connected to it 156 back to its final position on the pressure cylinder 07 opposite side in the shaft 143 , see. 14 , The pressing element 124 is from the printing cylinder 07 turned off and the alignment device 151 pans with their diametrical stops 152 ; 153 again preferably in a horizontal position.

With the method steps described so far is a change of a first printing plate 101 on the printing cylinder 07 completed by a used pressure plate 101 removed and a new pressure plate 101 was raised.

Changing a second pressure plate 101 is essentially in accordance with the method described above and further details will be to the already mentioned WO 2004/085160 A1 expressly referred.

Corresponding to the majority of on the respective plate cylinder 07 in the axial direction recorded printing plates 101 can preferably be provided in a manner not shown that in the plate changing device 11 in the axial direction of the plate cylinder 07 seen several printing plates 101 are arranged side by side. In this context, it is expedient if, in a likewise not-shown manner, each of the juxtaposed printing plates 101 in each case at least one pressing element 124 is assigned, it being particularly preferred if each at least one of a printing plate 07 associated pressing element 124 independently operable from the other printing plates 101 associated pressing elements 124 so that the feed or discharge for each printing plate 101 regardless of another printing plate 101 can be carried out.

For holding several printing plates arranged side by side 101 in the plate changing device 11 This can be a plurality of shaft-like areas 141 ; 143 or shafts 141 ; 143 have, wherein at least two shaft-like areas 141 ; 143 can be arranged lying side by side, but preferably the number of adjacent shaft-like areas 141 ; 143 the number of on the associated plate cylinder 07 in the axial direction juxtaposed printing plates 101 equivalent.

Furthermore, especially in the case of two on a plate cylinder 07 circumferentially arranged successively printing plates 101 be provided that in a plate changing device 11 two bay-trained areas 143 ; 141 are arranged one above the other. Here is one of the two superimposed areas 143 ; 141 a feeder level 143 , z. B. a Zuführschacht 143 and the other of the superimposed areas 141 ; 143 a discharge level 141 , z. B. a discharge duct 141 , In detail, the arrangement is expediently such that the plate changing device 11 one of the number of printing plates 101 on the associated plate cylinder 07 corresponding number of adjacent feed chutes 143 and a corresponding number from below the feed chutes 143 arranged discharge ducts 141 includes. The number of adjacent feed chutes 143 the plate changing device 11 may be four or six in particular.

In the case of several on a plate cylinder 07 juxtaposed printing plates 101 is every printing plate 101 one channel each 108 (see eg. 4 ) or a section of a channel 108 for receiving the angled front end 113 every printing plate 101 assigned. It is preferably provided that for side by side arranged printing plates 101 each a correspondingly long channel 108 is formed, in particular in the axial direction of the plate cylinder 07 can be formed continuously.

As described above in the channels 108 holding devices 119 for holding the suspension legs 113 the printing plates 101 provided (cf. 4 ), in particular the holding means 121 , the spring elements 122 and the adjusting means 123 may include. Order for each printing plate 101 a plate change independent of a plate change of another printing plate 101 in the case of several in the axial direction is to be able to design each other on a plate cylinder 07 arranged printing plates 101 for every printing plate 101 a separate holding device 119 provided and each holding device 119 is independent of the other holding devices 119 actuated, in particular pneumatically actuated.

While in the 9 to 14 the plate changing operation has been explained in the case that the production direction P with the direction in which the printing plates 101 supplied, that is, in the case of the printing units 03 ; 21 ; 29 ; 32 (see. 1 and 2 ), the plate changing process differs in the case of the other printing units 04 ; 22 ; 28 ; 31 in contrast, as follows:
First, it will open again 1 Referenced. It is assumed that in the nine cylinder satellite pressure unit 16 the printing material web 23 in the printing unit 22 with the color black, in the printing unit 04 with the color cyan, in the printing unit 03 with the color magenta and in the printing unit 21 printed with the color yellow one after the other. Accordingly, the wear the printing units 22 ; 04 ; 03 ; 21 associated printing plates 101 ; 101b ; 101c respectively. 101d print images 105 the corresponding color, namely the printing unit 22 associated printing plates 101 a printed image 105a for the color black, the printing unit 04 associated printing plates 101b a printed image 105b for the color cyan, which is the printing unit 03 associated printing plates 101c a printed image 105c for the color magenta and the printing unit 21 associated printing plates 101d a printed image 105d for the color yellow, cf. 5 ,

5 outlines the printing plates 101 ; 101b ; 101c and 101d in connection with the associated print images 105a ; 105b ; 105c and 105d for this nine-cylinder satellite printing unit 16 , At the same time, the orientation of the printed images 105a ; 105b ; 105c and 105d relative to the associated printing plates 101 ; 101b ; 101c respectively. 101d to recognize and by the respective arrow the production direction P or direction P of the respective printing plate 101 ; 101b ; 101c respectively. 101d on the corresponding plate cylinder 07 shown during production. The leading end of each print image in production 105a ; 105b ; 105c ; 105d is with the reference number 106 denotes the end of the production process trailing with the reference number 110 , It can be seen that the print images 105a and 105b opposite the printed images 105c and 105d in opposite orientation to the respective printing plates 101 respectively. 101b are applied. It can also be seen that the orientation of the printing plates 101 and 101b relative to the direction of production P is opposite to the orientation of the printing plates 101c and 101d , so that ultimately all the print images 105a ; 105b ; 105c and 105d are aligned in the same orientation to the production direction P.

The process of mounting the printing plates 101 ; 101b takes place in the case of printing units 22 and 04 now so that the appropriate printing plates 101 ; 101b with her first end 103 at the first front edge 116 of the plate cylinder 07 be hung and the direction of rotation of the corresponding plate cylinder 07 for the purpose of mounting the printing plates 101 ; 101b is reversed until even the second end 104 the printing plate 101 ; 101b at the second rear edge 117 of the plate cylinder 07 mounted and attached, and then that for a subsequent printing operation, the direction of rotation of the plate cylinder 07 again in the direction of production P is reversed. Here is in the case of these printing plates 101 ; 101b the running direction P in the printing operation so that the second end 104 , which according to the prior art is usually the trailing end, now represents the leading end.

The foregoing is for the overhead nine cylinder satellite pressure unit 17 applicable accordingly, in which case the printing units 31 ; 28 those printing works 31 ; 28 are where the printing plates 101c and 101d in printing operation leading second ends 104 have and applied in opposite to the prior art opposite orientation printed images 105c ; 105d wear. In the case of the nine-cylinder satellite pressure unit 17 are in the described embodiment, these printing units 31 ; 28 assigned the colors magenta or yellow.

In 15 the above facts are again sketched schematically. It shows different operating phases of the plate cylinder 07 for example, the printing units 29 ; 28 or 32 ; 31 , namely phase A, in which the first end 103 the respective printing plate 101 in the channel 108 of the plate cylinder 07 more precisely about its first leading edge 116 has been hung and the process of drawing up a printing plate 101 begins, Phase B, in which the plate cylinder 07 for mounting the printing plate 101 rotates and the pressure plate 101 already partially raised, phase C, in which the mounting of the printing plate 101 on the plate cylinder 07 is finished and therefore the second end 104 the printing plate 101 in the channel 108 more precisely on its second rear edge 117 mounted and where necessary has been fixed, and phase D, in which the plate cylinder 07 rotated for the purpose of printing in the direction of production P. The left column shows a plate cylinder 07 for example, the printing units 29 ; 32 and the right column shows a plate cylinder 07 for example, the printing units 28 ; 31 the nine cylinder satellite pressure unit 17 , In the nine-cylinder satellite printing unit 16 applies the same, but the arrangement is about a vertical M-M mirrored.

As seen from the left column of 15 can be seen, the plate cylinder rotates here 07 also during the phase of drawing up a printing plate 101c ; 101d in the direction of production P, while in the case of the right column, the direction of rotation D of the plate cylinder 07 when mounting a printing plate 101 ; 101b directed opposite to the direction of production P and is reversed again after mounting.

In the case of the embodiments described above, the circumference of the satellite cylinder corresponds 18 the circumference of the plate cylinder 07 or forme cylinder 07 ; in the case of a circumference of the plate cylinder 07 from one side, in particular newspaper page corresponds to the circumference of the satellite cylinder 18 also one side, especially newspaper page, in the case of a circumference of the plate cylinder 07 from two sides, in particular newspaper pages corresponds to the circumference of the satellite cylinder 18 also two pages, especially newspaper pages. The circumference of the satellite cylinder 18 is thus equal to the section length of the plate cylinder in the case of the first alternative mentioned above 07 and in the case of the second alternative mentioned above, equal to twice the section length of the plate cylinders 07 ,

Generally, the circumferential ratio of satellite cylinder 18 and plate cylinder 07 in particular be designed so that the circumference of the satellite cylinder 18 an integer multiple of the section length of the plate cylinder 07 equivalent.

In the 16 is an example of a part of the printing unit 21 of the printing tower 14 according to 1 shown; the other printing works 03 ; 04 ; 22 ; 28 ; 29 ; 31 ; 32 are trained accordingly.

In the illustrated example, the rotary press operates in a wet offset printing process. The transfer cylinder 06 generated with each of its revolutions on the substrate web 23 , preferably on a paper web 23 , at least one printed image. In the in the 16 illustrated operating case of the printing unit 21 are to the form cylinder 07 at least one inking unit 09 and a dampening unit 08 hired.

The inking unit 09 has several, preferably at least three rollers 203 ; 204 ; 206 , z. B. inking rollers 203 ; 204 ; 206 in the ongoing production process of the rotary printing machine to the forme cylinder 07 are employed. Between a printing ink from a paint reservoir 207 receiving ink ductor 208 and the ink on the form cylinder 07 applying inking rollers 203 ; 204 ; 206 are several rolls 209 ; 211 ; 212 ; 213 arranged. The color ductor 208 in the transport direction of the ink next roll 209 is as a film roller 209 educated. Then it is in the transport direction of the ink after the film roll 209 one as a paint separation roller 211 trained roller 211 provided, one of the Farbduktor 208 upcoming color flow 2A into a mainstream 2 B and into a side stream 2C divides. In the 16 is that to the form cylinder 07 leading course of the main stream 26 by a solid line and also to the forme cylinder 07 leading course of the sidestream 2C indicated by a dashed line.

In the main stream 2 B and in the side stream 2C each is one of the ink jet separating roller 211 on at least one of the inking rollers 203 ; 204 ; 206 Ink transferring roller 212 ; 213 arranged, this roller 212 ; 213 each as a rubbing roller 212 ; 213 is trained. The two friction rollers 212 ; 213 perform a running in their respective axial direction traverse stroke, the traverse stroke of a friction roller 212 z. B. by a lever assembly with the traverse stroke of the other friction roller 213 can be coupled. In an alternative embodiment, the traverse stroke of the respective friction roller 212 ; 213 generated by independent drives. In both drive variants, the two traversing strokes can be designed in opposite directions. The traverse stroke of the respective friction roller 212 ; 213 can z. B. be generated by means of a gear from the rotational movement. Both in the main stream 2 B as well as in the sidestream 2C gets out of the paint reservoir 207 taken ink each by means of a five juxtaposed rollers 208 ; 209 ; 211 ; 212 ; 213 ; 203 ; 204 ; 206 having roller compactor on the forme cylinder 07 applied, with the Farbduktor 208 , the film roller 209 , the paint separation roller 211 , one of the friction rollers 212 ; 213 and one of the inking rollers 203 ; 204 ; 206 each part of each of the form cylinder 07 leading compactors are. Between the ink ductor 208 and the paint separation roller 211 is therefore only a single roller in the compactor 209 arranged, this roller 209 as a film roller 209 is trained

As the main stream 2 B becomes that part of the color ductor 208 coming color stream 2A referred to, in the direction of rotation of the ink separation roller 211 from this color flow separation roller 211 taken off and being the first on the mainstream 2 B arranged rubbing roller 212 in the direction of the forme cylinder 07 is forwarded. The part of the ink fountain roller 208 coming color stream 2A in the direction of rotation of the ink separation roller 211 the main stream 2 B downstream of this color flow separation roller 211 removed and in the direction of the forme cylinder 07 forwarded is, is as a side stream 2C the one from the paint reservoir 207 taken referred to printing ink. The sidestream 2C can turn into further sub-streams 2D ; 2E be split when on the off-stream 2C arranged Reibwalze 213 several, in particular two of the inking rollers 204 ; 206 ; 203 are employed. Because the main stream 2 B of the color ductor 208 coming color stream 2A the form cylinder 07 in the direction of rotation first, ie at least spatially before the side stream 2C and its partial flows 2D ; 2E achieved, is such an inking 09 referred to as front-heavy. The in the side stream 2C of the color ductor 208 coming color stream 2A transported ink is z. B. on the main stream 2 B pre-colored form cylinder 07 applied. Also finds by the to the side stream 2C and its partial flows 2D ; 2E belonging inking rollers 204 ; 206 a smoothing of the main stream 2 B on the form cylinder 07 applied portion of the ink instead. Such an inking unit 09 creates a uniform application of ink on the form cylinder to be inked 07 , An inking unit 09 , whose main stream 2 B of the color ductor 208 coming color stream 2A the form cylinder 07 in the direction of rotation only after the on the forme cylinder 07 applied side stream 2C and its partial flows 2D ; 2E is applied, is referred to as Hinterlastig.

The color reservoir 207 from which the Farbduktor 208 the to the form cylinder 07 Removing ink to be transported, z. B. as a color box 207 or as a paint tray 207 trained, being at the color box 207 or on the paint tray 207 in the axial direction of the ink ductor 208 strung together several, z. B. thirty to sixty paint knives (not shown) are provided, which are preferably remotely operable with an adjusting means, not shown, in their respective employment of the ink fountain roller 208 adjustable and actually are also employed, creating a zonal dosing of the Farbduktor 208 recorded ink is possible. The adjustment made with the setting of the respective color meter dosage of the amount of color manifests itself in a proportional to this setting layer thickness of the ink in the relevant zone on the outer surface of the ink fountain 208 , The inking unit is accordingly designed in the preferred embodiment as a zone inking unit.

The rollers 203 ; 204 ; 206 ; 208 ; 209 ; 211 ; 212 ; 213 of the inking unit 09 have in their respective axial direction a length z. B. in the range of 500 mm to 2,600 mm, in particular in the range of 1,400 mm to 2,400 mm. Your outer diameter is z. B. in the range between 50 mm and 300 mm, preferably between 80 mm and 250 mm.

The ink separation roller 211 has a lateral surface preferably made of an elastic material, for. B. made of a rubber.

The dampening unit 08 is preferably as a dampening contactless applying dampening unit 08 , z. B. formed as a spray dampening, so it is a spray bar 219 preferably, more in the spray bar 219 arranged spray nozzles dampening solution on a z. B. as a dampening drive roller 221 trained roller 221 of the dampening unit 08 spray. That on the dampening roller 221 sprayed dampening solution is from another z. B. as a smoothing roll 222 trained roller 222 of the dampening unit 08 on its dampening roller 218 and from there to the form cylinder 07 transfer.

In the 16 is the direction of rotation of the respective rollers 203 ; 204 ; 206 ; 208 ; 209 ; 211 ; 212 ; 213 of the inking unit 09 that of the rollers 218 ; 221 ; 222 of the dampening unit 08 as well as the cylinders 06 ; 07 each indicated by an associated arrow. The cylinders 06 ; 07 are driven as described above. In the inking unit 09 is just one of the friction rollers 212 ; 213 either the rubbing roller 212 or the rubbing roller 213 by a drive 253 ; 254 , z. B. an electric motor 253 ; 254 driven. In the 16 the preferred embodiment is shown, in which the friction roller 212 is driven and the friction roller 213 has no engine. The other alternative should be indicated by the fact that for the friction roller 212 only in dashed line a drive 253 is shown. The remaining rolls 203 ; 204 ; 206 ; 208 ; 209 ; 211 of the inking unit 09 are friction-driven and thus do not have their own motor drive. To change the middle inking roller 204 to allow, is the upper rubbing roller 213 pivoted by a mechanical device in one direction, the axial distance a213 to the forme cylinder 07 enlarged so that the middle inking roller 204 essentially by a vertically upward movement from the area between the forme cylinder 07 and the upper rubbing roller 213 is removable.

The topmost inking roller 206 of the inking unit 09 is arranged such that in her to the forme cylinder 07 employed operating state to the scope of this inking roller 206 applied horizontal tangent T206 from one to the circumference of the forme cylinder 07 applied horizontal tangent T07 is located at a vertical distance a206 of at least 50 mm. This vertical distance a206 forms, as it were, an offset between the uppermost inking roller 206 and the form cylinder 07 out. This arrangement results from an operating side of the printing unit 21 from an adequate accessibility to the forme cylinder 07 , especially all the rest to the inking unit 09 belonging rolls 203 ; 204 ; 208 ; 209 ; 211 ; 212 ; 213 clearly below the at the periphery of the uppermost Inking roller 206 applied horizontal tangent T206 are arranged. The rollers 218 ; 221 ; 222 of the dampening unit 08 are essentially below the forme cylinder 07 arranged and also limit the accessibility to the forme cylinder 07 not a. The accessibility to the form cylinder 07 must z. B. therefore be given to on the lateral surface of the forme cylinder 07 in the shortest possible time one or more printing forms 101 to be able to change. A change of printing forms 101 can on the forme cylinder 07 automatically with the help of a to the form cylinder 07 preferably tangentially employed plate changing device 11 be executed.

Despite the comparatively small number of color gaps in the ink to the plate cylinder 07 transporting compactor generates the illustrated inking unit 09 on the plate cylinder 07 a uniform application of paint, because there are more rollers provided where they are particularly needed for smoothing the paint, namely in direct contact with the plate cylinder 07 where preferably three inking rollers 203 ; 204 ; 206 are provided. In particular, by a special, namely stochastic structure of the lateral surface of the film roll 209 will reach that inking unit 09 hardly tends to stenciling. The result is with this inking unit 09 Even in newspaper printing a printed product with a high print quality achievable, which takes into account the ever-increasing quality demands in newspaper printing. Even in a high-speed press with a transport speed of the substrate 23 of more than 10 m / s, preferably in the range between 10 m / s and 15 m / s, as is commonly used in newspaper printing, occurs due to the short roller train and the film roller used 209 the unwanted effect of color fog hardly on. The use of in the 16 described inking 09 in a rotary printing press, in particular as a printing tower 14 trained newspaper printing press, will be explained in the following figures.

17 and 18 show in a schematic sketch again in the 16 represented part of the printing unit 21 , now in particular the storage of the cylinder 06 ; 07 and a respective adjustment of the inking rollers 203 ; 204 ; 206 , the film roller 209 , the color separation roller 211 , the dampening roller 218 and the dampening roller 221 are highlighted. The representations in the 17 and 18 differ in that 17 shows a first operating state with preferably each closed compactors, which means that z. B. the inking rollers 203 ; 204 ; 206 to the form cylinder 07 and to one of the friction rollers 212 ; 213 are hired and that the dampener roller 218 to the form cylinder 07 and to the smoothing roller 222 is employed. 18 shows, however, a second operating state with preferably each open, ie interrupted by a gap pulleys, which means that z. B. the inking rollers 203 ; 204 ; 206 and / or the dampening roller 218 at least from the form cylinder 07 are turned off.

All rollers 203 ; 204 ; 206 ; 208 ; 209 ; 211 ; 212 ; 213 of the inking unit 09 , the rollers 218 ; 221 ; 222 of the dampening unit 08 as well as the cylinders 06 ; 07 are each arranged in spaced apart, standing opposite stands 02 respectively. 27 of the printing tower 14 ( 1 ) rotatably mounted, wherein at least the inking rollers 203 ; 204 ; 206 and the dampening roller 218 , but preferably also the film roller 209 and the paint separation roller 211 of the inking unit 09 as well as the dampening roller 221 of the dampening unit 08 are each arranged radially displaceable. The radial stroke of these rolls 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 refers to the fact that the respective axis of these rolls 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 or at least one of the ends of these rollers 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 opposite to the respective roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 belonging frame-fixed bearing point is eccentrically adjustable. The eccentric adjustment of each of the rollers 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 takes place in each case with the aid of preferably several, z. B. four each symmetrical and concentric about the respective axis of these rolls 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 arranged actuators 223 as exemplified in the 17 and 18 is shown, preferably even to the same roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 belonging to actuators 223 individually and independently operated by a control unit and can be adjusted to a specific travel, each actuated actuator 223 each with respect to the roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 to which it belongs, exerts a radial force, this force being the axis of this roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 moves radially or at least tries to move. If several at the same end of one of the rollers 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 arranged actuators 223 be operated simultaneously, resulting from the axis of the respective roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 executed radial stroke of a vector sum of the respective radial force of the actuators actuated 223 , The actors 223 be z. B. subjected to a pressure medium; Preferably, they are pneumatically operated. The actors 223 are z. B. in each case one end of the respective roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 receiving roller lock arranged. The from the axis of the respective roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 executable Radialhub is preferably in the range of a few millimeters, z. B. it is up to 10 mm, which is sufficient to the respective roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 of at least one adjacent cylindrical rotation body, z. B. the form cylinder 07 to turn off. It is also envisaged that with the respective actuators 223 one from the respective roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 is applied against its at least one adjacent rotating body applied contact pressure, wherein the degree of the set contact force by the controlled with this setting transport to printing ink or dampening influence on the quality of in conjunction with this inking 09 and / or dampening unit 08 generated printed product takes. The contact force is built up if there is already a physical contact between the respective roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 and its adjacent rotary body, but still by the operation of one or more actuators 223 the at least one effective radial force is increased. By further or renewed actuation of one or more actuators 223 can an existing contact force in their amount changed, for. B. also be reduced.

With the adjustment of the contact pressure, which is one of the rollers 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 also exerts on its adjacent body of revolution, a width of a in touch contact between this roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 and the adjacent rotational body forming roller strip set, wherein the roller strip as a flattening on the lateral surface of the roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 , on the lateral surface of the roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 represents co-acting cylindrical body of revolution or on the lateral surface of both. The width of the roll strip is the chord forming on the otherwise circular cross-section of the roll 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 or of the co-rotating body. The flattening is due to an elastically deformable lateral surface of the roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 or the cooperating with her body of revolution possible. A roll strip is also referred to as a nip point. In the the actuators 223 Controlling control unit can be stored values for their respective pressure level, to which the respective actuators 223 to adjust for a specific roller 203 ; 204 ; 206 ; 209 ; 211 ; 218 ; 221 through from the respective setting of the actuators 223 resulting contact force to form a roller strip of certain width to its adjacent body of revolution.

The cylinders 06 ; 07 ie the transfer cylinder 06 and the form cylinder 07 , are according to their representation in the 17 and 18 each in a storage unit 224 stored, preferably both ends of the respective cylinder 06 ; 07 each in such a storage unit 224 , z. B. Linear storage 224 are stored. The storage unit 224 allowed the respective cylinder 06 ; 07 a linear displacement S. Details of the bearing unit preferably used 224 are in the 19 shown.

The one on / off mechanism for each cylinder 06 ; 07 integrating storage unit 224 points next to a warehouse 226 , z. B. radial bearings 226 , For example, a cylindrical roller bearing 226 , for rotatory mounting of the respective cylinder 06 ; 07 bearing means 227 ; 228 for a radial movement of the respective cylinder 06 ; 07 - for pressure on or pressure off - on. For this purpose, the storage unit 224 after their installation in or on a frame of the printing press frame-fixed, carrier-resistant bearing elements 227 as well as against these movable bearing elements 228 on. The carrier-fixed and movable bearing elements 227 ; 228 are as cooperating linear elements 227 ; 228 and together with corresponding sliding surfaces or intermediate rolling elements as a whole linear bearing 227 . 228 educated. The linear elements 227 ; 228 in pairs take a radial bearing 226 receiving, z. B. as a sled 229 trained warehouse block 229 between themselves. bearing block 229 and the movable bearing elements 228 can also be made in one piece. The carrier-fixed bearing elements 227 are on a carrier 231 arranged, which in total with one of the racks 02 ; 27 ( 1 ) is connected. The carrier 231 is for example designed as a carrier plate which, for example, at least on a drive side of the respective cylinder 06 ; 07 a recess for the passage of a shaft, z. B. a drive shaft of an in 19 Having not shown cylinder pin. Also, the frame wall on the drive side preferably has a recess or an opening for a drive shaft. On the opposite side of the drive side does not necessarily have a recess or a recess in the frame 02 ; 27 be provided.

Preferably, a length of the linear bearing 227 . 228 , In particular, at least one length of the frame-fixed in the assembled state bearing means 227 of the linear bearing 227 . 228 , in the direction of the travel S considered smaller than a diameter of the associated cylinder 06 ; 07 , The storage block 229 preferably has only a single degree of freedom of movement in the direction of the travel S.

The storage unit 224 , which is preferably designed as a unit that can be assembled as a whole, forms z. B. an optionally partially open housing from z. B. the carrier 231 and / or z. B. a frame (in 19 without reference z. B. the four the storage unit 224 to all four sides outwards bounding plates). Within this housing or this frame are the radial bearing 226 bearing block 229 , the bearing elements 227 ; 228 , z. B. the linear guides 227 ; 228 , z. B. linear bearings 227 ; 228 and in an advantageous embodiment z. B. a storage block 229 linearly adjusting actuator 232 or several such actuators 232 accommodated. The frame-fixed bearing elements 227 are arranged substantially parallel to each other and define the direction of the travel S ( 19 ).

Pressure on is done by moving the bearing block 229 towards the pressure point by means of a by at least one actuator 232 on the storage block 229 applied force F, in particular by at least one force-controlled actuator 232 , By means of which for employment a defined or definable force F in pressure-on direction to the bearing block 229 can be brought ( 19 ). The decisive for the color transfer and thus the print quality, among other things, line force in the respective nip position is therefore not by a travel S, but by the balance of forces between the force F and one between the cylinders 06 ; 07 resulting line force F _L and the resulting equilibrium defined. In a first, not specifically illustrated embodiment, the cylinder 06 ; 07 in pairs put together by the bearing block 229 with the corresponding adjusted force F via the actuator (s) 232 is charged. For basic setting of a system (with corresponding elevators on the cylinders 06 ; 07 ) is provided in an advantageous embodiment that at least the respective transfer cylinder 06 of the printing unit 03 ; 04 ; 21 ; 22 ; 28 ; 29 ; 31 ; 32 can be fixed or at least wegbegrenzbar in an Anstelllage found by the balance of power.

Particularly advantageous is an embodiment in which the bearing block 229 - Even during operation of the printing press - at least in one of the pressure point pioneering direction against a force, eg. B. spring force, in particular a definable force, is movably mounted. This is - in contrast to the pure travel limit - on the one hand, a maximum line force in the interaction of the cylinder 06 ; 07 defined, and on the other hand allows yielding, for example, in a web break with subsequent winder on one of the cylinder 06 ; 07 ,

The storage unit 224 has on its side facing a pressure point - at least during the setting process - a location-adjustable stop 233 on, which limits the travel S to the pressure point out. The stop 233 is locally adjustable in that a stop surface effective as a stop 234 , whose reference numbers are in the 19 in an outbreak of the warehouse block 229 is shown along the travel S at least in one area is variable. It is thus adjustable by stop 233 provided in an advantageous embodiment, an adjusting device, by means of which the position of a pressure near the end position of the bearing block 229 is adjustable. For Wegbegrenzung / adjustment serves z. B. a wedge drive described below. Placing the stop 233 can basically be manual or via one as an actor 236 executed actuating means 236 respectively.

Next is an advantageous embodiment in 19 not shown holding or clamping means provided by means of which the stop 233 set in the desired location. Next is at least one spring-acting element 237 , z. B. spring element 237 , provided, which on the storage block 229 a force FR from the stop 233 in a direction away from there applies. Ie. the spring element 237 causes a pressure-off in the event that the bearing block 229 is not prevented from moving in any other way. Pressure on is done by moving the bearing block 229 in the direction of the stop 233 by at least one actor 232 , In particular a force-controlled actuator 232 , By means of which for employment of the respective cylinder 06 ; 07 optionally a defined or definable force F in pressure-on direction on the bearing block 229 can be brought. If this force F is greater than the restoring force FR of the spring elements 237 , so takes place with appropriate spatial training a hiring of the respective cylinder 06 ; 07 to the adjacent cylinder 06 ; 07 and / or hiring the storage block 229 to the stop 233 ,

Ideally, the applied force F, the restoring force FR and the position of the stop 233 chosen so that between stop 233 and the abutment surface of the bearing block 229 no significant force .DELTA.F is transmitted in the set position, for example, | ΔF | <0.1 · (F - F _R ), in particular | ΔF | <0.05 * (F - F _R ), ideally | ΔF | ≈ 0. In this case, the contact force between the cylinders 06 ; 07 much above that by the actor 232 applied force F determined. The decisive for the color transfer and thus the print quality, inter alia, line force F _L in the respective nip point is therefore not primarily by a travel S, but at quasi-free stop 233 defined by the force F and the resulting equilibrium. Basically, after finding the basic setting with the appropriate forces F would be a removal of the stop 233 or a corresponding, effective only during the basic setting fixation conceivable.

The actor 232 can basically as any, a defined force F applying actuator 232 be executed. The actuator is advantageous 232 as actuatable by a pressure medium actuating means 232 , in particular as a piston movable by a fluid 232 executed. Advantageous in terms of possible tilting is the arrangement of several, here two, such actuators 232 , As fluid preferably comes because of their incompressibility a liquid, for. B. an oil or water, used.

To operate here as a hydraulic piston 232 executed actuators 232 is in the storage unit 224 a controllable valve 238 intended. This is executed, for example, electronically controlled and provides a hydraulic piston 232 in a first position without pressure or at least to a lower pressure level, while in another position, the force F conditional pressure 2P is applied. In addition, a non-designated leakage line is provided here for safety.

In order to avoid excessive stopping / stopping distances and still to secure track winders, it can be found on the side of the bearing block away from the pressure side 229 a Wegbegrenzung by a mobile, force-limited stop 239 as overload protection 239 z. B. be provided in conjunction with a spring element, which in the operative pressure-off position, ie the piston 232 are relieved and / or retracted, although as a stop 239 for the storage block 229 serve, in the case of a railway winder or other originating from the pressure excessive forces, however, gives way and a larger way is free. A spring force of this overload protection 239 is therefore chosen larger than the sum of the forces from the spring elements 237 , When operational on / off is therefore only a very short travel, z. B. only 1 mm to 3 mm, providable.

The stop 233 is in the illustrated embodiment ( 19 ) as a transversely movable to the direction of the travel S wedge 233 executed, wherein when moving the same position of the respective effective stop surface 234 varies along the travel S The wedge 233 relies, for example, on a carrier fixed stop 241 from.

The one here as a wedge 233 executed stop 233 is by an actor 236 movable, for example by a pressure medium actuable actuating means 236 , z. B. a piston operable with a pressure medium 236 in a working cylinder with (double-acting) piston via a z. B. as a piston rod 242 executed transmission element 242 or by an electric motor via a transmission element designed as a threaded spindle 242 , This actor 236 may be either in both directions effective or, as shown here, designed as a one-way actuator, which when activated against a return spring 243 is working. The force of the return spring 243 is for the above reasons (largely force-free stop 233 ) so weak that the wedge 233 is held only in its correct position against gravity or vibration forces.

Basically, the stop 233 in another way (for example, as a plunger adjustable and fixable to the adjusting direction, etc.) in such a way that it can be varied in the direction of the travel S, and - at least during the setting process - fixable stop surface 234 for the movement of the storage block 229 forms in the direction of the pressure point. In an embodiment, not shown, a place of the stop takes place 233 for example, directly parallel to the direction of the travel S by a drive means, for example, a pressure medium actuated cylinder with (double-acting) piston or an electric motor.

It will now be based on the embodiments 20 to 24 Reference is made to avoid repetition expressly to the description in connection with the embodiments 1 to 19 Reference is made, as far as relevant.
