Description
Rotary printing machine The invention relates to a rotary printing machine having at least one integrated image-setting device for a printing form which, during image setting, is fixed to a form cylinder that can be driven in rotation in relation to the image-setting device.
A printing machine of this type is described in DE 197 23 147 A1. This printing machine contains two different drive systems. During printing operation, a main drive is used to drive all the components which are needed for printing and which are coupled to one another via a gear train. During the image-setting operation, an auxiliary drive is used to drive the form cylinder separately, the main drive being stopped and the form cylinder being uncoupled from the gear train with the aid of isolating clutches. It is necessary to stop the main drive in order not to permit mechanical oscillations and shocks which are produced during the operation of the main drive acting on the image-setting system comprising the image-setting device and form cylinder. These mechanical oscillations and shocks would cause image-setting errors and printing errors. During image-setting, the auxiliary drive, in addition to the form cylinder, can also be used to drive components which cause only slight mechanical oscillations.
After image-setting, the form cylinder must be coupled into the main drive train in the correct phase, to which end special precautions have to be taken. Linking the form cylinder into the gear train again in the correct phase can be monitored by measuring systems or can be carried out by mechanical means, such as phase clutches.

In order to avoid printing errors DE 94 03 673 A1 discloses the art of compensating for mechanical oscillations in the printing machine during image-setting by means of corrective driving of the image-setting heads in the circumferential direction.
It is an object of the invention to develop a rotary printing machine which has a low outlay on material and cost when driving a form cylinder during printing and image-setting operation.
The object is achieved by a rotary printing machine which has the features as claimed in claim 1.
Advantageous refinements emerge from the subclaims.
The use of a speed-change gear mechanism between the gears driving the form cylinder during printing operation and the form cylinder itself, has the advantage that during the setting of an image on the printing form, the rotary printing machine is driven in a noncritical oscillation range, while the form cylinder is driven, in accordance with the transmission ratio of the speed-change gear mechanism, is driven at a multiple of the rotational speed of the remaining components in the drive train of the rotary printing machine for the purpose of setting an image. Depending on the natural oscillation characteristics of the rotary printing machine, the speed-change gear mechanism may be designed with different transmission ratios. The remaining rotational oscillations in the drive train and the effects thereof on the image-setting process are low, because of the low rotational speed. As a result, the image-setting quality can be increased. The drive gear train does not need to be isolated for the image-setting operation. A dedicated drive for the form cylinder during r II~I~ill~ll 9' ~ ~ I
image setting is not required. The speed-change gear mechanism can be engaged and disengaged automatically before and after the setting of an image. The form cylinder can be coupled to a rotary encoder, which supplies the current rotational speed and the cylinder position to control electronics during the setting of an image.
The invention is to be explained in more detail using an exemplary embodiment; in the drawing:
fig. 1 shows a schematic diagram of a four-color rotary printing machine, fig. 2 shows a schematic drawing of the drive of a form cylinder, fig. 3 shows a detailed view of the epicyclic gear mechanism of fig. 2 during printing operation, and fig. 4 shows a detailed view of the epicyclic gear mechanism of fig. 2 during image-setting operation.
A sheet-fed printing machine 1 shown in fig. 1 contains a feeder 2, four printing units 3, 4, 5, 6 and a deliverer 7.
Each printing unit 3-6 contains a form cylinder 8, a transfer cylinder 9, an impression cylinder 10, two transfer cylinders 11, 12, a large number of ink transfer rolls 13 and damping-solution transfer rolls 14, and image-setting devices 15.
Transfer drums 16 are arranged between the printing units 3-6.
Further cylinders 17, 18 are used to supply sheets 19 to the first printing unit 3. In the deliverer 7 there are diffraction cylinders 20, 21, over which the chains 22 of a chain gripper system are placed. The cylinders and rolls in the printing units 3-6, and also all the rotationally driven cylinders or drums in the feeder 2 and deliverer 7 are connected to one another by a gear mechanism. A further gear train 23-25 acts on the gear of the transfer cylinder 12/4 of i~iii~ni~,f r~ I ~ i the second printing unit 4. From the shaft of the gear 25 there is a belt pulley 26 belonging to a belt drive 27. The second belt pulley 28 is seated on the shaft of a main drive motor 29. The main drive motor 29 and the speed-change gear mechanism 30 are connected to a control device 31 belonging to the sheet-fed printing machine 1. In addition to further actuators and sensors, the image-setting devices 15 are also connected to the control device 31.
During printing operation, sheets 19 are conveyed from the feeder 2 through the printing units 3-6 to the deliverer 7, the main drive motor 29 driving all the components via said gear mechanism. The speed-change gear mechanisms 30 are out of action. During the driving of the sheet-fed printing machine 1, harmonic and nonharmonic oscillations are produced as a result of eccentricities, imbalance and subassemblies which are moved to and fro, such as oscillating grippers or gripper mechanisms. The effects of the oscillations and shocks on the printing quality are reduced during printing by the high pressure between the transfer cylinders 9 and the respective printing cylinders 10.
During image-setting operations, in order to avoid circumferential and axial oscillations, the form cylinder 8 is driven via the speed-change gear mechanism 30. During image-setting operation, the transfer cylinders 9 are thrown off the form cylinders 8 and the impression cylinders 10.
Using fig. 2 and fig. 3 the intention below is to use printing unit 3 to describe how the drive of the form cylinder 8 is carried out during printing operation and during image-setting operation. Fig. 2 shows a sectional illustration of a side wall 32 of the sheet-fed printing machine 1. The side wall 32 contains bearings 33, 34 to accommodate the shaft journals 35, I I'.;

36 of the form cylinder 8 and of the transfer cylinder 9.
Fixed on the shaft journal 35 is a gear 37 belonging to the gear train for driving the transfer cylinder 9 during printing. On the shaft journal 36, a gear 38 is arranged such that it can rotate in a bearing 39. The gear 38 is combined in structural terms with a further gear 90 in order to drive the inking and damping units. The gear 38 is continuously engaged with the gear 37, and gear 40 is continuously engaged with a further gear 41.
Also assigned to the gear 38 is an epicyclic gear mechanism 42. The epicyclic gear mechanism 42 comprises an internally toothed gear 43, four uniformly distributed planet gears 44-47 and an internally located central gear 48. The gear 43 is formed on the outer surface of a section turned out of the gear 38. The planet gears 44-47 are connected to the gear 43 and the gear 48. The planet gears 44-47 run on bearings 49-52, which are fixed to bolts 53-56, which are fixed to the turned-out portion of the gear 38. The central gear 48 is connected to the shaft journal 36 by a key 57 and can be displaced in the axial direction on the shaft journal 36. The central gear 48 further has a lateral ring gear 58, with which a lateral ring gear 59 on the gear 38 is associated. In order to displace the gear 48 in the axial direction, a fixed-position pulling magnet 60 is provided. On its pulling armature 61 there is a roller 62 which engages in a circumferential groove 63 which is machined in a connecting piece 64 on the gear 48.
During printing operation, the pulling magnet 61 with the roller 62 is in the position shown in fig. 3. The ring gear 58 is engaged with the ring gear 59. If the gears 37 and 38 are set rotating via the main drive motor 29 and the gear train, then the torque is transmitted to the form cylinder 8 via the ring gears 59, 58, the key 57 and the shaft journal 36.
A printing machine of this type is described in DE 197 23 147 A1. This printing machine contains two different drive systems.

36 of the form cylinder 8 and of the transfer cylinder 9.
Fixed on the shaft journal 35 is a gear 37 belonging to the gear train for driving the transfer cylinder 9 during printing. On the shaft journal 36, a gear 38 is arranged such that it can rotate in a bearing 39. The gear 38 is combined in structural terms with a further gear 90 in order to drive the inking and damping units. The gear 38 is continuously engaged with the gear 37, and gear 40 is continuously engaged with a further gear 41.
Also assigned to the gear 38 is an epicyclic gear mechanism 42. The epicyclic gear mechanism 42 comprises an internally toothed gear 43, four uniformly distributed planet gears 44-47 and an internally located central gear 48. The gear 43 is formed on the outer surface of a section turned out of the gear 38. The planet gears 44-47 are connected to the gear 43 and the gear 48. The planet gears 44-47 run on bearings 49-52, which are fixed to bolts 53-56, which are fixed to the turned-out portion of the gear 38. The central gear 48 is connected to the shaft journal 36 by a key 57 and can be displaced in the axial direction on the shaft journal 36. The central gear 48 further has a lateral ring gear 58, with which a lateral ring gear 59 on the gear 38 is associated. In order to displace the gear 48 in the axial direction, a fixed-position pulling magnet 60 is provided. On its pulling armature 61 there is a roller 62 which engages in a circumferential groove 63 which is machined in a connecting piece 64 on the gear 48.
During printing operation, the pulling magnet 61 with the roller 62 is in the position shown in fig. 3. The ring gear 58 is engaged with the ring gear 59. If the gears 37 and 38 are set rotating via the main drive motor 29 and the gear train, then the torque is transmitted to the form cylinder 8 via the ring gears 59, 58, the key 57 and the shaft journal 36.
r n~nlw<I~~ s~ ~ ~ '.
Because the ring gears 58, 59 are engaged, the epicyclic gear mechanism 42 is blocked. The rotational speed of the form cylinder 8 is given by the numbers of teeth and diameters of the gears 37 and 38.
During image-setting operation, the pulling armature 61 with the roller 62 is in the position shown in fig. 4. The ring gears 58, 59 are disengaged. When the gear 38 is driven via the gear 37, the planet gears 44-47 run around the central gear 38. The rotational speed of the gear 48 and of the form cylinder 8 is increased by a multiple of the input rotational speed at the gear 43, in accordance with the radii of the gears 43, 44-47, 48. Therefore, the gears arranged upstream of the gears 38, 37 in the drive train can be operated with a low rotational speed, so that no or very few mechanical disturbances on the systems comprising image-setting devices 15 and form cylinders 8 are produced.
The invention is not restricted to the epicyclic gear mechanism illustrated in the exemplary embodiment and having fixed-point ring gears 58, 59. Any desired speed-change gear mechanism can be used which has the effect that, during image-setting operation, the drive train is operated in a rotational speed range in which no disruptive oscillations or shocks occur. In this case, the transmission ratio of the speed-change gear mechanism can be matched to the natural oscillation range of the rotary printing machine.
The control device 31 is used to control the main drive motor 29, the pulling magnet 60 or similar adjusting device, and to control the image-setting devices 15. The control device 31 can contain a program which has the effect that the speed-change gear mechanism 30 is automatically connected up with a higher transmission ratio when the rotary printing machine 1 ayiiruii9 s;
is switched from printing operation to image-setting operation.
