The invention relates to a cylinder of a printing unit of a rotary printing machine with one or more elevators according to the preamble of claim 1.

From the WO 01/39977 A1 a printing unit of a rotary printing machine with at least one transfer cylinder and at least one forme cylinder is known, wherein the transfer cylinder has a channel for receiving one or more blankets and the forme cylinder at least two circumferentially successively arranged channels for receiving one or more printing plates, wherein at least one of the channels of Form cylinder is at least partially covered by a printing plate and wherein the at least partially covered channel of the forme cylinder in the region of a channel for receiving one or more blankets of the cooperating transfer cylinder rolls. Moreover, this document describes that the printing plates can be arranged with their ends offset in the circumferential direction to each other in different channels or that the forme cylinder in the axial direction next to each other at least two printing plates or a plurality of circumferentially successively arranged printing plates may have, wherein in the case of several over the entire circumference arranged printing plates these can be arranged with their ends in the circumferential direction alternately offset from each other.

The DE 22 20 652 A1 describes a device for securing flexible printing plates on the plate cylinder of a rotary printing press, the device having arranged on the same axis clamping jaw pairs, which are arranged about an axis parallel to the cylinder axis, extending over the entire length of the cylinder pivotally mounted in a cylinder channel in the cylinder body , A clamping jaw pair consists of a jaw and a Jaw, wherein both the clamping jaw and cooperating with their clamping jaw about an axis parallel to the cylinder axis and pivotally mounted from the front side of the cylinder can be actuated. In the described embodiment, four clamping jaw pairs in the cylinder circumferential direction are arranged alternately once on one half of the cylinder length and once on the other half of the cylinder length. To adapt the device to printing plates of different format widths is provided between two adjacent clamping jaw pairs a short clamping jaw pair as an extension piece such that it is coupled in the cylinder body with the adjacent clamping jaw pairs and thus pivoted in the same manner as the clamping jaw pairs can. In each cylinder channel two coaxially arranged connecting shafts are provided, which are rigidly connected to a arranged in one half of the cylinder length clamping jaw pair and make a torque of the other half belonging end face of the cylinder on the connected to the connecting shafts clamping jaw pair transferable. The connecting shafts are therefore also pivotally mounted in the cylinder channel as the associated with them clamping jaw pair.

From the DE 199 24 786 A1 a device for clamping and / or clamping of flexible plates with folded Einhänbringeln is known, which protrude into a mounting slot of a cylinder supporting the plates, the mounting slot in the radial direction of the cylinder with an axis-parallel cylinder pit in conjunction, wherein in the cylinder pit in Moving clamping and / or clamping elements are provided within the interior of the base body, wherein the base body may consist of a plurality of shorter mutually detachable base bodies. The one or more arranged in a row in the cylinder pit base bodies are rotatably connected to each other, for example by means of a toothing, wherein a first and a last of the base body rotationally fixed in each case with an Endkuppelstück is connected, which is fastened with its cylinder pit covering parts on the flanks of the cylinder, for example by screwing.

The invention has for its object to provide a cylinder of a printing unit of a rotary printing machine with one or more elevators.

The object is achieved by the features of claim 1.

The advantages that can be achieved with the invention are, in particular, that inexpensive base bodies and filling elements can be arranged in an easy-to-install manner in the channels of the cylinder. In particular, the filling elements can be assembled to almost any desired length. An opening provided with a channel, which is partially covered by an elevator, holds for this elevator the risk of breakage when unrolling on a counter-cylinder in a printing unit. This danger does not exist with a cylinder with channels which have an opening only in those sections where this opening is required for mounting an elevator on the lateral surface of the cylinder.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below.

In the Fig. 1 a cylinder 01 of a printing unit of a rotary printing machine is exemplified. This cylinder 01 may be configured as a forme cylinder 01 a or as a transfer cylinder 01 b and may be arranged in the circumferential direction next to each other with z. B. an elevator and axially, ie its length L with z. Four elevators 02a; 02b; 02c; 02d, so that there are four vertical or horizontal lifts on the cylinder 01 ( Fig. 5 ).

In the case of a forme cylinder, the elevators are preferably designed as plate-shaped printing plates; in the case of a transfer cylinder, the elevators are preferably rubber blankets each applied to a carrier plate.

The printing unit can, for. Example, be designed as a 9-cylinder satellite printing unit in which four pairs each consisting of a forme cylinder 01 a and a transfer cylinder 01b are arranged in a frame around a common impression cylinder, wherein the forme cylinder 01a and transfer cylinder 01b respectively the features of have proposed solution here. Especially for the newspaper printing arrangements are favorable ( Fig. 2 ), in which a forme cylinder 01a in its axial direction in a first row z. B. with six plate-shaped printing plates 02a; 02b; 02c; 02d; 02e; 02f and - in the Fig. 2 only indicated - on the not visible in the representation page of the forme cylinder 01a in a second row z. B. with another six plate-shaped printing plates 02g; 02h; 02i; 02J; 02k; 02l is occupied, so that the forme cylinder 01a along its circumferential direction next to each other carries two plate-shaped printing plates. Such a forme cylinder 01a rolls on a transfer cylinder 01b, the z. B. axially with three juxtaposed rubber blankets 02m; 02n; 02o is occupied, each rubber blanket 02m; 02n; 02o spans the full extent of the transfer cylinder 01 b. The rubber blankets 02m; 02n; 02o have in this example twice the width and length of the plate-shaped printing plates 02a to 02l. The total with z. B. twelve plate-shaped printing plates 02a to 02l occupied form cylinder 01 a and the total of z. B. two rubber blankets 02m; 02n; 02o occupied transfer cylinder 01b in this case preferably have the same geometric dimensions with respect to the length L of their bale and its circumference. The plate-shaped printing plates 02a to 02l are with their respective ends 03; 04 on the forme cylinder 01a in two circumferentially offset by 180 ° channels 11; 12 attached, whereas the respective ends 03; 04 of rubber blankets 02m; 02n; 02o are held in at least one channel 11`. The forme cylinder 01 a and the transfer cylinder 01 b are preferably arranged in the printing unit such that their respective channels 11; 11` roll on each other. For the sake of completeness, it is noted that the forme cylinder 01a can also be occupied by elevators designed as panorama printing plates, so that each plate-shaped printing form contains two printed image pages in each case. In this case, those in the Fig. 2 for the elevators assigned reference numerals 02a to 02l on the printed image pages, wherein the printed image pages 02a; 02b and 02c, respectively; 02d and 02e, respectively; 02f or 02g; 02h or 02i; 02j or 02k; 02l are each arranged on a panoramic printing plate.

If now, as will be described later, elevators are arranged offset in the circumferential direction of the cylinder to each other, this means in the case of using Panorama printing plates that not the individual printed pages, but arranged on the lateral surface 13 of the cylinder 01a, each consisting of two printed pages panorama printing plates are arranged offset from one another. In order to allow a staggered arrangement of elevators, in a cylinder with two channels, the elevators must either fully span the cylinder circumferentially, with both ends of the same elevator fixed in the same channel and the ends of an adjacent elevator in the other channel, or are in the Cylinder but more than two channels provided, such. B. four channels, which are each offset by 90 ° to each other, so that in each case z. B. two elevators circumferentially one behind the other can be arranged, the ends of each elevator are mounted in two different, each offset by 180 ° channels and adjacent elevators are secured in the offset by 90 ° channels.

The cylinder 01; 01 a; 01 b has a diameter D1 of, for example, 160 mm to 340 mm, preferably between 280 mm and 300 mm. The axial length L of the bale of the cylinder 01, 01a; 01 b is z. B. in the range between 1200 mm and 2400 mm, preferably between 1900 mm and 2300 mm Fig. 1 , A plate-shaped printing plate or a support plate for a rubber blanket is usually made of a flexible, but otherwise dimensionally stable material, eg. B. of an aluminum alloy, and has two opposite, in or on the cylinder 01; 01 a; 01 b to be fastened ends 03; 04 with a material thickness M of z. B. 0.2 mm to 0.4 mm, preferably 0.3 mm, said ends 03; 04 for training Einhänbringeln 06; 07 each along a bending line 08; 09 with respect to the extended length I of the elevator 02a to 02o by an angle α; β are bent between 40 ° and 140 °, preferably 45 °, 90 ° or 135 ° ( Fig. 3 ). When only a single elevator 02m to 02o is juxtaposed in the circumferential direction of the cylinder 01b, the length l of the elevator 02m to 02o corresponds to almost the length of the circumference of the cylinder 01b.

In the in the Fig. 1 shown example, a first channel 11 and a second channel 12 are provided in the cylinder 01, wherein both channels 11; 12 extend continuously in the direction of the length L of the cylinder 01 and in the direction of its circumference z. B. are offset by a 180 ° spanning circular arc to each other. To avoid imbalance of the rotating cylinder in the printing cylinder 01, it is advantageous, the channels 11; 12 equidistant, ie to arrange at equal distances from each other. A variant to that in the Fig. 1 shown arrangement with continuous channels 11; 12 is when at least one of the channels 11; 12 extends only over a portion of the length L of the cylinder 01, wherein this portion does not necessarily have to be arranged on the edge of the lateral surface 13 of the cylinder 01, but may be located between the end faces of the cylinder 01 in the interior of the lateral surface 13 of the cylinder 01 ,

Both channels 11; 12 are in the interior of the cylinder 01 at a distance a of z. B. 4 mm to 10 mm, preferably 6 mm under the lateral surface 13 as a preferably circular bore through the cylinder 01 and each have a diameter D2 of z. B. 25 mm to 50 mm, preferably 30 mm. The ratio of the diameter D1; D2 from the cylinder 01 to the channel 11; 12 is thus preferably at 10: 1. When the cross-sectional area of the channels 11; 12 is not circular, the ratio of the cross-sectional areas of the cylinder 01 to one of the channels 11; Preferably at 100: 1, such that the cross-sectional area of the channels 11; 12 is comparatively small to that of the cylinder 01.

In the in the Fig. 1 shown example, both channels 11; 12 in its longitudinal direction in so many sections A; B; C; D split, as elevators 02a; 02b; 02c; 02d can be arranged side by side on the lateral surface 13 of the cylinder 01, wherein the sectionwise division of the lateral surface 13 of those of the channels 11; 12 corresponds. The channels 11; 12 have in some of their sections A; B; C; D a narrow, slit-shaped opening 14 to the lateral surface 13 of the cylinder 01 on ( Fig. 5 ). It is advantageous if in the circumferential direction of the cylinder 01 with respect to the same section A; B; C; D a provided with an opening 14 channel 11 with a closed to the lateral surface 13 of the cylinder 01 channel 12 alternates. This results in terms of the channels 11; 12 both in the circumferential direction and in the longitudinal direction of the cylinder 01, an alternating arrangement of openings 14 in the sections A; B; C; D.

The slot width S of the opening 14 is less than 5 mm and is preferably in the range of 1 mm to 3 mm ( Fig. 4 ).

As the Fig. 5 can recognize, corresponds in this example, the number of in each channel 11; 12 arranged side by side in the longitudinal direction, provided with an opening 14 sections A; B; C; D half of the length L of the cylinder 01 offset juxtaposed elevators 02a; 02b; 02c; 02d. If the lateral surface 13 of the cylinder 01 is occupied in the circumferential direction next to each other with more than one elevator, more than two, each spaced in a particular circular arc channels or sections of channels are provided and it results from the larger number of elevators complex occupancy arrangements on the Lateral surface 13 of the cylinder 01.

In this example, the number of elevators 02a; 02b; 02c; 02d and sections A; B; C; D are each selected to four, here each section A; B; C; D¼ the length L of the cylinder 01 has. As the Fig. 5 indicated in a developed view of the lateral surface 13 of the cylinder 01, all elevators are 02a; 02b; 02c; 02d on the lateral surface 13 of the cylinder 01 in the axial direction next to each other and the elevators 2b and 02d offset to the elevators 2a and 2c arranged such that these elevators 2b and 02d cover the sections B and D of the channel 12, whereas the elevators 2a and 2c Cover the sections A and C of the channel 11. The channel 11 has only in the sections B and D an opening 14 to the lateral surface 13 of the cylinder 01, while the channel 12 in the sections A and C each have a corresponding opening 14. The elevators 02a; 02b; 02c; 02d span in this example in each case the entire circumference of the cylinder 01. Thus, the ends 03; 04 of the elevators 02a; 02c fixed in the same channel 12, whereas the ends 03; 04 of the elevators 02b; 02d are secured in the other channel 11. Every elevator 02a; 02b; 02c; 02d thus covers each section A; B; C; D one of the two channels 11; 12, while he with his two ends 03; 04 in the other channel 11; 12 is attached. In this example, with reference to a across all sections A; B; C; D and on the lateral surface 13 of the cylinder 01 in parallel with a channel 11; 12 extending line whose position by the location of a channel 11; 12 is given, each section adjacent to an opening 14 of a closed to the lateral surface 13 of the cylinder 01 section. Along this line, the openings 14 introduced into the lateral surface 13 of the cylinder 01 are aligned with each other.

The at the ends 03; 04 of each elevator 02a to 02o molded suspension legs 06; 07 are inserted into the respective opening 14. It is advantageous in each case to mount a suspension leg 06 of each elevator 02a to 02o in a form-fitting manner on a first wall 17, this first wall 17 being bounded by an opening P of the cylinder 01; 01a; 01b leading edge 16 of the opening 14 to the interior of the channel 11 ';11; 12 extends. The angle α formed at one end 03 of the elevator 02a to 02o preferably corresponds to the angle α which extends between this first and the interior of the channel 11 ';11; 12 extending wall 17 and an imaginary, resting on the opening 14 tangent T results. The other suspension leg 07 of each elevator 02a to 02o can be applied to a second wall 19, wherein this second wall 19 of a in the direction of production P of the cylinder 01; 01a; 01 b trailing edge 18 of the opening 14 to the interior of the channel 11`; 11; 12 extends. Again, the angle β formed at one end 04 of the elevator 02a to 02o advantageously corresponds to the angle β which exists between the second one to the interior of the channel 11`; 11; 12 extending wall 19 and an imaginary, resting on the opening 14 tangent T gives ( Fig. 3 and Fig. 4 ).

As in Fig. 4 is shown, is for fixing the elevators 02a to 02o on the lateral surface 13 of the cylinder 01; 01 a; 01b in those sections A; B; C; D of the channel 11 ';11; 12, which have an opening 14 to the lateral surface 13, a holding device is provided, wherein the holding device consists of at least one clamping piece 21 and a spring element 22. The inserted into the opening 14 suspension leg 07 ( Fig. 3 ) at the trailing end 04 of the elevators 02a to 02o is preferably applied to the second wall 19 of the opening 14 and pressed there by the clamping piece 21 by a force exerted by the spring element 22 on the clamping piece 21 force F. To release the clamping is in the channel 11`; 11; 12 an adjusting means 23 is provided, which counteracts in its actuation of the force exerted by the spring element 22 on the clamping piece 21 force F and the clamping piece 21 pivots away from the second wall 19 of the opening 14.
