It is going on first Fig. 1 Reference is made, which shows one of two stacked, six-plate wide printing units 16 and 17, in particular of nine-cylinder satellite printing units 16 and 17 (6/2 printing units) composed, designed as a four-tower 14 printing tower 14 shows. The lower, six-plate wide nine-cylinder satellite printing unit 16 comprises a frame 02, a cylinder mounted on the frame 02 18, z. B. a satellite or impression cylinder 18, two lower, cooperating with the satellite cylinder 18 printing units 03; 04 and two upper, with the satellite cylinder 18 cooperating Printing units 21; 22nd

Each printing unit 03; 04; 21; 22 each includes a cylinder 06, z. B. a trained as a blanket cylinder 06 transfer cylinder 06, a cylinder 07, z. B. a designed as a plate cylinder 07 form cylinder 07, a plate cylinder 07 associated dampening unit 08 and the plate cylinder 07 associated inking 09. The dampening 08 can be, for example, brush dampenings, film dampenings or spray dampenings. The dampening units 08 are arranged outboard to be flexible in the choice of the direction of rotation in the later possible retrofitting. Two plate cylinders 07 each; 07 are arranged horizontally next to each other and thus lie on a common horizontal H.

The blanket cylinders 06 of the two lower printing units 03; 04 are arranged at a small distance from each other and employed to the impression cylinder 18. The blanket cylinder 06 of the two overhead printing units 21; 22 are arranged at a great distance from each other and have in the case of the embodiment at an angular distance α of about 150 °. The blanket cylinder 06 of the upper two printing units 21; 22 may have an angular distance α of at least 90 ° or at least 120 ° or at least 140 °.

Between the two upper printing units 21; 22 or their rubber cylinders 06 is a guide roller or a pair of guide rollers 19 arranged such that the printing material or paper web 23 is not subtracted from the rubber cylinders 06, that does not wrap around them, which is essential for the possibility of using an imprinter. Furthermore, in the space between the incoming and the outgoing paper web 23 sufficient space to accommodate a counter-pressure cylinder cleaning device 24, which may be installed through the wall of the frame 02 through, if necessary. The cleaning of the impression cylinder 18 can in this case without removing the Paper web 23 done.

The blanket cylinders 06 of the printing units 21; 22 is assigned in each case a blanket washing device 12. The two rubber cylinders 06 of the two lower printing units 03; 04 is assigned a common blanket washing device 26, which can be adjusted from below vertically upwards to the two blanket cylinders 06 and with which the two associated blanket cylinders 06, possibly after removal of the impression cylinder 18, can be cleaned. Other arrangements of the blanket washing devices 12 are possible.

The plate cylinders 07 of the printing units 03; 04; 21; 22 is associated with a plate changing device 11, in order to automate the laying of printing plates on the respective plate cylinder 07 and accelerate. The plate changing devices 11 may be those which are explained in more detail below. These plate changing devices 11 are, for example, in the printing unit 16; 17 arranged so that at least one pressure plate 101 can be initially introduced without curvature.

The drive concept for this embodiment may be, for example, five or six drives for the nine cylinder satellite pressure unit 16. Not least because of the spatially close position of the blanket cylinders 06 (small formats), the plate cylinders 07 are preferably driven, of which then, for example, when driven in pairs on the blanket cylinder 06.

The upper nine-cylinder satellite pressure unit 17 is similar in construction to the lower nine-cylinder satellite pressure unit 16, but has a mirrored structure on the other hand. With regard to a detailed description, reference may therefore be made to the above. In particular, therefore, the arrangement of the printing units 03; 04; 21; 22 or cylinder 06; 07; 18 of a printing unit 16 in mirror image to the arrangement of Printing units 28; 29; 31; 32 or cylinder 06; 07; 18 of the other printing unit 17. In addition, the plate changing devices 11 of a printing unit 16 are arranged in mirror image to the plate changing devices 11 of the other printing unit 17th

The upper nine-cylinder satellite pressure unit 17 thus has a frame 27 with holes which are formed in mirror image to those of the frame 02. Optionally, the frame 27 or parts thereof may be formed identical to the frame 02, but rotated by 180 ° placed on the frame 02, which has a favorable effect on the manufacturing cost. Of course, instead of the two stacked frames 02; 27 also a single common frame for the two nine-cylinder satellite printing units 16; 17 and the printing tower 14 may be provided.

The upper nine-cylinder satellite printing unit 17 thus again comprises a counter-pressure cylinder 18 serving as a satellite cylinder 18 and four printing units 28 arranged thereon; 29; 31; 32. The blanket cylinder 06 of the two lower printing units 28; 29 are now arranged at a great distance from each other, while the blanket cylinder 06 of the two upper printing units 31; 32 are arranged at a small distance from each other. The upper two printing units 31; 32 are arranged in the manner of a U-printing unit.

In the four-high tower 14, the printing substrate 23 to be printed is fed by a cylinder 33 approximately vertically down the lower nine-cylinder satellite pressure unit 16, printed here on one side in four-color printing, then approximately vertically upward fed to the upper nine-cylinder satellite pressure unit 17, here on printed on the other side in four-color printing and then fed approximately vertically down a cylinder 34.

If the above-described, according to the offset printing process printing units 03; 04; 21; 22; 28; 29; 31; 32 working according to another printing method, For example, after an indirect gravure printing or waterless planographic printing, it is understood that in this case the dampening 08 omitted.

The embodiment according to Fig. 2 In terms of general construction, it corresponds substantially to that according to FIG Fig. 1 , so that reference is made to it and in the following essentially only the differences reference will be explained. The same or corresponding components are provided with the same or corresponding reference numerals.

In the case of the embodiment according to Fig. 2 In particular, the position of the dampening units 08 is partly different from that according to FIG Fig. 1 , While in the case of the embodiment according to Fig. 1 all dampening units 08 extend approximately radially to the satellite cylinder 18 and are arranged practically immediately adjacent to the corresponding inking units 09, extend in the case of the embodiment according to Fig. 2 the dampening units 08 of the printing units 04; 21; 28; 32 are approximately perpendicular to such a radial direction or, in other words, these dampening units 08 relative to the embodiment according to Fig. 1 opposite to the direction of rotation of the respective plate cylinder 07 offset on the circumference by orders of magnitude 90 °. In this way, space is created on the circumference of the respective plate cylinder 07 to allow for these plate cylinders 07 an arrangement of a plate changing device 11 between the inking unit 09 and dampening unit 08.

Specifically, the plate changing devices 11 are arranged on the plate cylinders 07 so as to always enclose an acute angle with the incoming cylinder surface of the respective plate cylinder 07, which is essential for proper operation of the plate changing device 11, as will be apparent from later-described embodiments. By design, this then leads to a part of the plate changing devices 11 from above with the respective corresponding plate cylinder 07 cooperates, while another part the plate changing devices 11 from below cooperates with the respective corresponding plate cylinder.

It can therefore be differentiated between the top feeding and discharging plate changing devices 11a and from below feeding or discharging plate changing devices 11 b. In the case of the embodiment according to Fig. 2 are the printing units 03; 21; 29; 32 associated plate changing devices 11 from top to remove or discharging plate changing devices 11a, while the printing units 04; 22; 28; 31 associated plate changing devices 11 from below, or laxative plate changing devices 11 b are.

The basic structure of a preferred embodiment of a plate changing device 11 will now be explained in connection with the structure and operation of an example of a top-feeding or discharging plate changing device 11a.

A preferred embodiment of the duct 141 provides that at least two pressure plates 101 can be stored next to one another in the shaft 141 in the axial direction of the pressure cylinder 07. This embodiment allows a particularly rapid removal of printing plates 101, in particular when at least two printing plates 101 can be arranged on the printing cylinder 07 in its axial direction, because a plurality of printing plates 101 can be removed simultaneously from the printing cylinder 07.

At the pressure cylinder 07 side facing the shaft 141 for receiving the printing cylinder 07 remote printing plates 101 at least in the employee employed on the printing cylinder 07 operating state a close to the lateral surface 107 of the printing cylinder 07 arranged guide member 173 which z.

B. a roller 173 is formed and has the task of leading the trailing end 104 of a printing cylinder 07 to be removed pressure plate 101 in the well 141. A distance a73 of the guide element 173 of the lateral surface 107 of the printing cylinder 07 is preferably not much greater than the length of the folded Einhänlegeels 114 at the trailing end 104 of the pressure plate 101. On the guide member 173 may be mounted a sensor 191, either in contact with the printing cylinder 07 to be removed pressure plate 101 or advantageously contactless, z. B. inductive, checks whether the suspension leg 114 has actually solved at the trailing end 104 of the printing cylinder 07 to be removed pressure plate 101 after actuation of the arranged in the channel 108 of the printing cylinder 07 holding means 121.

In a preferred embodiment, the suspension leg 114 at the trailing end 104 of the printing plate to be removed by the printing plate 07 101 after passing through the guide member 173 preferably on a spaced from the guide member 173 arranged first ramp 174 before it reaches the support 172 in the shaft 141, wherein the first ramp 174 initially rises in the direction of the support 172 and, after a summit point 176, drops towards the support 172. The first ramp 174 is preferably rigidly connected to the support 172. In the course of the introduction of the print cylinder 101 to be removed from the pressure plate 101 in the well 141 meets their suspension leg 114 at the trailing end 104 on a second ramp 177, the flank after its summit point 178, d. H. So on the side facing away from the printing cylinder 07 side, preferably abruptly drops steeply to support 172 out. In the direction in which the pressure plate 101 is inserted into the shaft 141, a stop 179 rigidly connected to the second ramp 177 is arranged a short distance behind the summit point 178, against which the suspension leg 114 abuts the trailing end 104 of the pressure plate 101. When the suspension leg 114 abuts against the stop 179 at the trailing end 104 of the pressure plate 101, it preferably engages behind the second ramp 177, in that the suspension leg 114 engages in the intermediate space formed by said distance.

The second ramp 177 and its associated stop 179 are connected by a Conveying device 181 linear and parallel to the support 172 movable to completely remove the printing cylinder 07 to be removed from the printing plate 101 into the slot 141 into it. The conveyor 181, which forms in particular together with the steep flank on the second ramp 177 for the folded suspension leg 114 at the trailing end 104 of the pressure plate 101 a pressure plate 101 in the well 141 promotional entrainment is z. B. as a belt drive 181 or as a linear drive 181, preferably as a pneumatic linear drive 181, in particular as a rodless, double-acting linear drive 181 is formed.

On the side facing away from the printing cylinder 07 side a lift 182, in particular a pressure molding lifter 182 is arranged in the shaft 141, wherein the printing form lifter 182, for example, a preferably perpendicular to the support 172 movable piston 183, at the end of a z. B. L-shaped, in particular U-shaped lifting arm 184 is arranged, wherein the bent suspension leg 114 is set at the trailing end 104 of the pressure plate 101 on the lifting arm 184 or set encompassing. The printing form lifter 182 preferably has two stable operating positions, namely a stable operating position with the piston 183 retracted, in which the lifting arm 184 is below the level defined by the support 172, and another stable operating position with the piston 183 extended, in which the lifting arm 184 the pressure plate 101 removed from the pressure plate 101 of the support 172 lifts. The printing form lifter 182 executes a stroke s82, which is greater than the length of the folded Einhäniebels 114 at the trailing end 104 of the pressure plate 101. Preferably, the stroke s82 has a value between the single and double the length of Einhänlegeels 114. The printing form lifter 182 thus lifts a printing plate 101 removed from the printing cylinder 07 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 arranged about a substantially parallel to the width B of the pressure plate 101 extending pivot axis pivotable securing element 186, for. B. in the form of a strip-shaped flap 186, whose or the lower edge is located at a distance a86 from the lifting arm 184, wherein the distance a86 is preferably dimensioned smaller than the length of the folded Einhäniebels 114 at the trailing end 104 of the pressure plate 101st In the Fig. 9 indicates a direction arrow to the pivoting of the fuse element 186. The securing element 186 secures a printing plate 101 raised by the printing form lifter 182 against unintentional slipping in the shaft 141 or removal from the shaft 141. Thus, an operator first has to pivot the securing element 186 before the lifted printing plate 101 can be removed from the shaft 141.

The Fig. 11 to 14 By way of example, several stages of the process sequence for changing printing plates 101 on a plate cylinder 07 are assumed. First of all, two printing plates 101 are arranged in the upper shaft 143 to provide new printing plates 101 to be mounted on the printing cylinder 07, along the printing cylinder 07 from the periphery of two printing plates 101 are placed and that the lower slot 141 for receiving the printing cylinder 07 remote printing plates 101 is empty, ie free of printing plates 101, see. Fig. 11 , The printing cylinder 07 rotates the opening 109 of a channel 108, in which the suspension leg 114 is held at the trailing end 104 of the pressure cylinder 07 to be removed pressure plate 101 by a holding means 121, in a first position, which is below the lower shaft 141 belonging to the guide member 173 is located. The pressure element 124 is turned on the pressure cylinder 07 ( Fig. 11 ).

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

The pressure cylinder 07 then rotates counter to its production direction P and pushes the trailing end 104 of the pressure plate 101 into the shaft 141. When the pressure plate 101 is inserted into the shaft 141, the suspension leg 114 first slides on the trailing end 104 of this pressure plate 101 along the guide element 173 and then positions itself on the first ramp 174 belonging to the shaft 141. The suspension leg 114 slides the ramp 174 up to about the summit point 176 and then reaches the support 172. While the pressing member 124 is still employed on the printing cylinder 07, the pressure plate 101 is rotated by the rotation of the impression cylinder 07 against its production direction P in the slot 142nd inserted. In this case, its suspension leg 114 at the trailing end 104 also overcomes the second ramp 177 connected to the conveying device 181 and abuts against the stop 179 connected to the second ramp 177.

Now the pressing element 124 is turned off by the printing cylinder 07. By the impact of Einhänlegeels 114 of the trailing end 104 on the stop 179, the form-fitting hinged to the front edge 116 of the opening 109 folded becket 113 at the leading end 103 of the pressure plate 101 from the opening 109. The pressure plate 101 is now with its leading end 103 freely on the lateral surface 107 of the printing cylinder 07 on. The printing cylinder 07 has performed from the release of the Einhänlegeels 114 at the trailing end 104 until now less than half a turn. The bent suspension leg 114 at the trailing end 104 has hooked between the second ramp 177 and the stop 179. The conveying device 181 connected to the second ramp 177 and the stop 179 can now completely draw the pressure plate 101 into the shaft 141, cf. Fig. 11 ,

The pressure plate 101 is now removed from the printing cylinder 07 and is in its length L in the shaft 141. Its suspension leg 114 at the trailing end 104 rests on the summit point 178 of the second ramp 177, while its leading end 103 on the summit point 176 of the first ramp 174 rests, whereby at least the suspension leg 113 at the leading end 103 preferably hangs freely. The storage of the printing plate 137 in the shaft 141 is thus preferably carried out by a support at two points, namely on the summit points 176; 178 of the two ramps 174; 177th

The z. B. pneumatically actuated printing form lifter 182 now raises the retracted into the well 141 pressure plate 101 at its trailing end 104 to briefly below the fuse element 186, wherein the suspension leg 114 rests on the associated with the printing forme lifter 182 lifting arm 184, see. Fig. 12 ,

For mounting a printing plate 101 to be mounted on the printing cylinder 07, the latter first rotates counter to its production direction P into a receiving position. The first pressure plate 101 to be mounted on the printing cylinder 07 is in contact with its suspension leg 114 at its trailing end 104 on the stop 156 connected to a conveying device 157. The conveyor 157 is set in operation, so that the stop 156 in a direction preferably directed tangentially to the printing cylinder 07 movement the first printing plate 101 as far from the shaft 143, until its leading end 103 touches the Anrückelement 124 attached to the printing cylinder 07 and the this leading end 103 bent support legs 113 between the rear in the production direction P of the printing cylinder 07 edge 117 of the opening 109 and the contact point 188 of the pressure element 124 on the impression cylinder 07, see. Fig. 13 ,

The printing cylinder 07 now changes its direction of rotation and begins to rotate in its production direction P, as a result of which the suspension leg 113 set up on the printing cylinder 07 projects at the leading end 103 of the printing plate 101 into the opening 109 slips and hooked form-fitting manner on the front edge 116 of the opening 109. Due to the further rotation of the printing cylinder 07 in its production direction P, the printing plate 101 is completely conveyed out of the shaft 143 and mounted on the printing cylinder 07. During the winding process, the pressure plate 101 is rolled onto the impression cylinder 07 by the pressing element 124 attached to the impression cylinder 07. After half a rotation of the printing cylinder 07 in its direction of production P, the pressing member 124 presses the folded suspension leg 114 at the trailing end 104 of the pressure plate 101 in the opening 109. The holding means 121 in the opening 108 belonging to this channel 108 was released and is then in that Operating position brought in which it introduced into the opening 109 suspension leg 114 at the trailing end 104 of the pressure plate 101 z. B. fixed by a clamp. The conveyor 157 drives the stop 156 connected to it again into its end position on the side facing away from the printing cylinder 07 side in the shaft 143, see. Fig. 14 , The pressure element 124 is turned off by the pressure cylinder 07 and the alignment device 151 pivots with its diametrical stops 152; 153 again preferably in a horizontal position.

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

The replacement of a second printing plate 101 takes place essentially in accordance with the method explained above, and further details are referred to above WO 2004/085160 expressly referred.

As already mentioned, the printing units 03; 21; 29; 32 associated plate changing devices 11 from the top of the supply or discharge plate changing devices 11 a, as they are based on the Fig. 9 to 14 were explained in more detail, while the printing units 04; 22; 28; 31 associated plate changing devices 11 from the bottom or discharge leading plate changing devices 11 b, as they are based on Fig. 15 were explained.

In a group of plate changing devices 11, namely, the plate changing devices 11a, which are fed and discharged from above, the folded front ends 113 of the printing plates 101, that is, the suspension legs 113, are thus down, while in the other group of plate changing devices 11, namely, those from below feeding and discharging plate changing devices 11b facing upwardly bent edge ends 113 of the printing plates 101; this preferably applies both to the respective feed chute 142; 143 as well as for the respective discharge chute 141; 144th
