a ten-satellite printing unit.

A printing press, in particular a web-fed rotary printing press, has at least one printing unit 01. The printing unit 01 has at least one cylinder 02, which is embodied as a counter-pressure cylinder 02, on which at least two cylinders 03 or 04, eg. B. several transfer cylinder 03 in the indirect printing process or multiple forme cylinder 04 in direct printing process can be adjusted. The impression cylinder 02 is designed as a satellite cylinder 02, the printing unit 01 as a satellite printing unit 01.

The advantageous embodiment of the printing unit 01 as a nine-cylinder satellite printing unit 01 ensures a very good Passerhaltigkeit or a low fan-out. But it can also be designed as a ten-cylinder satellite printing unit 01.

The printing unit 01 has several, in the example four printing units 06, by means of which ink from an inking unit 07 on the forme cylinder 04 on a the impression cylinder 02 looping web can be applied. In the present example, the printing unit 06 is executed as an offset printing unit 06 for the wet offset and has in addition to the inking 07 a dampening 08 and a o.g. Transfer cylinder 03 on. The transfer cylinder 03 forms a pressure point with the impression cylinder 02. In the direct process, the forme cylinder 04 forms the pressure point with the impression cylinder 02. The same parts are given the same reference numerals, as far as they are not necessary for differentiation. However, a difference in the spatial position may exist and remains in the case of awarding the same reference i. d. R. unconsidered.

The following drive and supply concepts are basically for all printing units 01 (for direct or indirect printing method) of advantage, in which a Impression cylinder 02 and at least one, in particular two, with this cooperating cylinder 03; 04 by different drive motors 09; 12 are driven. Particularly advantageous is the execution of the impression cylinder 02 with two drive motors 09 in conjunction with wide printing units 06, z. B. at least twice, in particular three times wide, ie for the pressure of four, in particular six axially juxtaposed newspaper pages.

The forme cylinder 04 has z. B. a circumference between 900 and 1300 mm, in particular from 940 to 1200 mm. The scope is z. B. for receiving two stationary printed pages, z. B. newspaper pages in the broadsheet format, by means of two in the circumferential direction on the forme cylinder 04 successively fixable elevators, z. B. flexible printing forms formed. The printing plates can be mounted in the circumferential direction on the forme cylinder 04 and, for example, in each case individually replaceable as a single printing plate equipped with a printing side in the axial direction. A length of the usable bale of the forme cylinder 04 is z. B. 1,850 to 2,400 mm, in particular 1,900 to 2,300 mm and is in the axial direction for receiving z. B. at least six juxtaposed standing printed pages, especially newspaper pages in broadsheet format, measured. It is u. a. Depending on the nature of the product to be produced, whether in each case only one pressure side or more pressure sides in the axial direction are arranged side by side on a printing plate. In an even wider variant of the design, the length of the usable bale is between 2,000 and 2,400 mm.

The transfer cylinder 03 has in the exemplary embodiment also has a scope z. B. between 900 and 1300 mm, in particular from 940 to 1200 mm. The length of the usable bale of the transfer cylinder 03 is z. B. 1,850 to 2,400 mm, in particular 1,900 to 2,300 mm and is in the longitudinal direction of each other z. B. with three lifts, z. B. blankets, occupied. They extend in the circumferential direction substantially to the full extent. The blankets are beneficial to the vibration behavior of the printing unit in the operating case, advantageously alternating, z. B. by 180 °, offset from one another. In the wider version is the length of the usable bales also between 2,000 and 2,400 mm.

A ratio of a length of the usable bale of the cylinders 03; 04 to the diameter should be 5.8 to 8.8, z. B. at 6.3 to 8.0, in a broader version but especially at 6.5 to 8.0.

The length of the usable bale here is the width or length of the bale to understand, which is suitable for receiving elevators. This corresponds approximately to a maximum possible web width of a web to be printed. Based on an entire length of the bale of the cylinder 03; 04 would be added to this length of usable bale still the width of any existing bearer rings, possibly existing grooves and / or possibly existing lateral surface areas, which z. B. for the operation of clamping and / or clamping devices must be accessible.

In an advantageous embodiment, the impression cylinder 02 also essentially has the dimensions and ratios of at least the assigned transfer cylinder 03.

The rotary drive of the printing unit 01 is now carried out in such a way that the impression cylinder 02 of the printing unit 01 mechanically independent of the cylinders 03; 04 of the printing units 06 is driven. Indicates the printing unit 01 as in Fig. 1 shown only a counter-pressure cylinder 02, so this is mechanically independent of the other cylinders 03 by two drive motors 09; 04 driven. On the one hand this enables a backup function, but in particular a unified engine size and an even load distribution (see below). In an advantageous embodiment, a gear 11, in particular at least one reduction gear 11 (such as pinion, intent and / or planetary gear) is arranged between the drive motor 09 and the driven cylinder 02.

In an in Fig. 1 illustrated advantageous embodiment, the printing unit 01 is driven so that the printing units 06 each at least by one of the others Pressure units 06 and the impression cylinder 02 mechanically independent drive motor 12 are rotationally driven. The drive motors 12 are preferably as with respect to their angular position controlled electric motors 12, z. B. as induction motors, synchronous motors or DC motors. In an advantageous embodiment is between the drive motor 12 and the driven cylinder 03; 04 or cylinder pair 03, 04 at least one gear 13, in particular at least one reduction gear 62 (such as pinion, attachment and / or planetary gear) arranged. The individual drives contribute to high flexibility and to avoid vibrations in the mechanical drive system, and thus also to high quality in the product.

In Fig. 1 have form and transfer cylinder 03; 04 in pairs a common drive motor 11. The drive can be coaxial, z. B. via a gear 13, on one of the cylinder 03; 04 and from there to the other cylinder 04; 03 done or as explained in more detail below about a pinion and a drive wheel. The drive connection (shown as a connecting line) can be done as a gear connection or via belt. For the rotary drive of the ink and possibly dampening unit 07; 08 each have their own drive motors 14; 16 or a the color and associated dampening unit common drive motor 14 or 16 may be provided. With a pairwise drive of the cylinder 03; However, in view of a cost-effective and control-technically robust solution, 04 is also a drive from the forme cylinder 04 without advantage of its own drive motor.

The cylinders 02; 03; 04 represent in their respective pressure-on position friction gear. Between the cylinders 02; 03; 04 can, for. B. due to different conveying behavior and / or surface properties, a power exchange via the friction gear. For example, z. B. in so-called positive-promoting lifts on the transfer cylinder 03, the impression cylinder 02 be driven in one case on the transfer cylinder 03, wherein the drive motors 09 are then operated as a generator and the transfer cylinder 03 by motor. Conversely, z. B. in so-called. Negative promotional lifts on the transfer cylinder 03, the Counter-pressure cylinder 02, the transfer cylinder 03 to be driven with the drive motors 09 then motorized and the drive motors 12 are operated as a generator.

The drive motors 09; 12 of the printing unit 01 are connected via at least one supply unit 17, z. B. power supplies 17, supplied with electrical power. This is done, for example, from the supply unit 17 via lines 19 to a respective drive motor 09; It is essential that the two drive motors 09 are supplied with electrical power by at least one supply unit 17, by means of which at least one drive motor 12 of a printing unit 06 is also supplied. This ensures that energy generated by regenerative operation does not have to be completely destroyed by heat, but can be fed back into the respective other drive. The risk of overload (in regenerative and / or motor operation) of the supply units 17 is significantly reduced, since at significant power exchange via the friction gear always a power between a printing unit 06 and the impression cylinder 02 is moved, which on the common supply unit 17 again at least partly traceable.

In the event that the drive motors 09; 12 of the printing unit 01 are supplied via several, here two supply units 17, it is of particular advantage that the impression cylinder 02 is driven by two drive motors 09. The two drive motors 09 are supplied with electrical power by various supply units 17, by means of which in each case at least one drive motor 12 of a printing unit 06 is also supplied. Thus, it is ensured for both supply units 17 that a energy generated by regenerative operation does not have to be completely destroyed by heat, but can be fed back into the respective other drive. Again, the risk of overloading the supply units 17 from o.g. Reasons significantly reduced.

The controllers 18 and controls 18 are in addition to the electrical energy of a Control device 21, which has, for example, a virtual (electronic) master axis or represents transmitted signals to a desired angular position and / or target speed. The controller 18 then regulate z. B. according to this setpoint specification, the power supply (motor) or -abfuhr (regenerative, braking effect).

In the following Fig. 2 to 5 Various advantageous drive configurations are shown on a nine-cylinder printing unit 01.

The two in Fig. 2 invisible cylinder 03; 04 each printing unit 03 each have mutually meshing drive wheels 22; 23 (eg gears 22, 23) and are driven via a pinion 24 by a common drive motor 12 on the transfer cylinder 03. However, the drive can also coaxial, z. B. via an unillustrated, og attachment gear, done. From the drive wheel of the transfer cylinder 17 is then on the drive wheel 23 of the forme cylinder 03, and possibly from there to the inking and / or dampening unit 07; 08 driven. The drive connection between the two cylinders 03; 04 can also be done via belt. The counter-pressure cylinder 02 is here driven by the two drive motors 09 via pinion 26, which drives on a common drive wheel 27 or on two different axially mutually offset drive wheels 27 of the impression cylinder 02. Between the drive motors 09; 12 and the drive wheels 22; 27 can still further transmission elements, such. As gears and / or belt drives, may be provided. The drive assembly is of particular advantage in terms of a clear moment flow in the printing unit 06 from the transfer cylinder 03 to the forme cylinder 04 and then eg color and possibly dampening unit 07; 08. The power supply is designed such that the drive motors 12 of the left printing units 06 are supplied together with a drive motor 09 of the impression cylinder 02 by a power supply unit 17 and the rest by the other power supply unit 17.

In contrast to Fig. 2 the two cylinders 16; 17 each printing unit 13 in the execution to Fig. 3 Although each of a common drive motor 12, but driven on the forme cylinder 04. The drive can again axially, z. B. over a not shown gear, done or via the on the drive wheel 23 of the forme cylinder 04 driving pinion 24. From the drive wheel 23 of the forme cylinder 04 can then be driven onto the drive wheel 22 of the transfer cylinder 03. The drive connection as well as the drive of the inking and possibly dampening unit 07; 08 can be like Fig. 2 be explained set forth. The drive arrangement is of particular advantage with regard to an adjusting movement of the transfer cylinder 03, without therefore a high cost in the storage of the drive motor 12 and / or compromises in the gear engagement would have to be considered. The power supply is exemplarily designed such that the drive motors 12 of the upper printing units 06 are supplied together with a drive motor 09 of the impression cylinder 02 by a power supply 17 and the rest by the other power supply 17. The supply scheme off Fig. 3 can on the drive concept of Fig. 2 applied and vice versa.

In a further development of the execution Fig. 3 , without own rotary drive of the inking and / or dampening unit 07; 08, it is advantageous from the forme cylinder 04 on the transfer cylinder 04 and from there, for example via a gear train, on the inking and / or dampening unit 07; 08 to drive. Thus, a clear torque flow ß achieved and possibly otherwise occurring tooth flank changes can be avoided.

In the example below Fig. 4 In each case two pairs 03, 04 are driven together in a drive network by a drive motor. It is driven by the two transfer cylinders 03 to "outside" (torque flow). In a variant not shown may be driven by one of the two forme cylinder 04 of the drive assembly, wherein between the drive wheels 22 of the transfer cylinder 03 is provided at least one intermediate. The drive wheel 27 and the drive wheels 27 are as to Fig. 2 described driven. The concept provides for the supply of a respective drive motor 09 together with one of the drive motors 12 of the two drive assemblies.

In Fig. 5 all cylinders have 03; 04 of the printing units 06 each have their own drive motor 12, which, for. B. each have a not shown, coaxial (Intentional) gearbox, substantially coaxial with the cylinder 03; 04 drives. For this purpose can advantageously angle and / or offset compensating couplings between the rotor and the transmission output and the journal of the respective cylinder 03; 04 be provided. However, the drive by the drive motor 12 can not coaxial in the above-mentioned manner, but via pinion 24 or belt drives on drive wheels 22; 23 done. The impression cylinder 02 is again driven by means of the two drive motors 09. The inking unit 07 shown above has, among other, not designated rolls z. B. two distribution cylinders, which are rotatably driven together by means of the own drive motor 14 via a dashed line indicated transmission. They are axially movable and driven for generating an axial stroke, for example by another, not shown drive means. The inking unit may also have only a distribution cylinder. The above applies to the drive of the dampening unit 08 in the same way. The concept provides for the supply of the drive motors 12 of two printing units 06 together with a drive motor 09 of the impression cylinder 02.

Those in the examples too Fig. 2 to 5 shown drive variants and supply concepts are also to be applied to printing units or parts of printing units, in which only two pairs 03, 04 with a common impression cylinder 02 together.

Fig. 6 shows a side view of the drive for the impression cylinder in the embodiment with a rotationally rigidly connected to the impression cylinder 02 drive wheel 27. On this is by a respective drive motor 09, z. B. via an auxiliary gear 11, and a pinion 26 driven. In unillustrated embodiment, the two pinions 26 drive on two axially offset drive wheels 27th

Fig. 7 shows a satellite printing unit 01 with two satellite cylinders 02, which are each associated with two printing units 06. For the printing units 06 with color and possibly dampening unit 07; 08 applies the above and the same reference numerals. In contrast to the embodiments according to Fig. 1 to 6 However, here each of the two impression cylinders 02 has its own drive motor 09. For the coupling between Drive motor 09 and the cylinder 02 is o. However, it may be provided for reasons of space also a substantially coaxial with the cylinder 02 arranged drive motor 09 which drives, for example via a not shown coaxial transmission to the cylinder 02.
The too off Fig. 2 to 5 described supply concepts of the drive motors 09; 12 and the drive concepts of the printing units 06 are applicable here. The only difference to the above examples is that the corresponding Fig. 2 to 5 supplied drive motors 09 not on the same impression cylinder 02, but drive on two different impression cylinder 02.

In a development, in particular suitable for wide printing units (see above), two drive motors 09 are provided per impression cylinder 02. In this case the supply concepts are the FIGS. 2 to 5 be applied so that the two associated drive motors 09 each a supply unit 17 and the other two of the other supply unit 17 are added.

In the embodiments, the drive motors 12 are preferably as with respect to their angular position controlled electric motors 12, z. B. as induction motors, synchronous motors or DC motors. The two drive motors 09 can also be designed in this way. This is especially true if as in Fig. 7 two counter-pressure cylinders 02 each have a drive motor 09 is assigned.

However, if an impression cylinder 02 has two drive motors 09, it is advantageous if one of the two drive motors 09 is regulated with respect to its angular position, and the other drive motor with respect to its moment (or its output). The angular position-controlled drive motor 09 acts here z. B. as "master", while the other drive motor 09 is tracked as a "slave" torque-controlled.

In a refinement of the energy return of the power flows arising from the friction gears, all drive motors 09; 12, the cylinder 02; 03; 04 of the printing unit 01 on a common supply unit 17. The supply unit 17 is - as well as the two above-described supply units 17 - designed to lead from regenerative drive drive power derived at least to a significant extent in the drive power for the motor drive back. A named power supply 17 for supplying several drives in the manner described has, for example, a power supply from a local network (printing or energy supplier), through which only energy is fed into the power supply unit, but can not be fed back from this. One (or more in common) independent of other drives speed and / or position-regulating drive motor 09; 11, the power supply 17, for example, a converter (in particular frequency converter), the power requirement is fed from a common circuit. Electrical energy, which from a generator-driven drive motor 09; 12 flows back, can in this way a motor betriebenben drive motor 12; 09 are supplied. This energy is therefore not turned into heat alone, but made available to another consumer. A generator-operated drive without dispensing possibility to a consumer would possibly overheat.

At least, in an advantageous embodiment, each operating motor (pressure-on) operated in generator mode is drive 09; 12 (in particular 09) of a same printing unit at least one drive motor 12 which is operated by a motor during operation; 09 assigned via the common power supply 17. In a particularly advantageous embodiment, all the drive motors 09; 11 of a printing unit 01 - in particular nine-cylinder printing unit 01 - connected to each other via a common power supply unit 17 in such a way that of the or the generator-operated in pressure-on drive motors 09; 12, at least a significant proportion of the power for driving the motor-driven drive motor or motors 12; 09 is supplied. From a generator-driven drive motor 09; 12 thus flow energy, z. B. drive energy, in particular electrical energy, via the power supply unit 17 in the motor-driven drive motor 12; 09th
