Drive device and a method for controlling an aggregate of a printing press

The invention relates to a drive device and a method for controlling an aggregate of a printing press according to the preamble of claim 1 or 24.

DE 37 30 625 A1 a drive device is known, wherein each printing unit or the folder of a printing machine is assigned a primary station, which receives operating setpoints from a higher-level control and to the

Transfers secondary stations of relevant modules.

DE 42 14394 C2 discloses a drive device for a longitudinally shaftless printing machine, wherein the folder is connected by data technology via a bus with groups of pressure points. The folder delivers its position reference to the print point groups. A drive control common to the drives of a single group of print groups performs the fine adjustment of these drives with each other and in relation to the folder.

In US 4495 582 A a drive of a printing press line is described by a common drive motor, wherein an incremental encoder is arranged in the region of a punch. Signals from this encoder are z. B. used as a reference for the circumferential register.

The invention has for its object to provide a drive device and a method for controlling an aggregate of a printing press.

The object is achieved by the features of claim 1 and 24, respectively.

In printing presses are used to control various units, eg. Stacker, dryer, register controller, etc., speed actual values or position values of the printing press in a variety of forms, eg. B. analog, incremental with different resolution, with or without zero pulse needed. This form depends u. U. also from the supplier. In order to provide the corresponding signals, a number of different encoders were physically arranged on one or more of the aggregates which provided the information for aggregates in the desired form not coupled to a mechanical and / or virtual longitudinal and / or standing wave.

Advantageously, the circuit according to the invention and its connection to a virtual master axis, in particular with regard to the parameterability and the ability to output a plurality of differently parameterized signals.

Since the signals are not obtained from encoders physically arranged in aggregates, the solution is characterized by high flexibility, space savings and a reduced susceptibility to disturbances, which would result, for example, from out-of-round aggregates or encoders.

The advantages which can be achieved with the invention are, in particular, drives of units whose controllers require position specifications as input variables, as well as drives of units which are not coupled directly to the lead axle, flexibly connect to the lead axle without much effort.

With the position reference from the electronic master axis for the printing units and possibly for the folder and a specification of the clock for other units occurring errors compared to mechanical measuring and / or drive systems are reduced.

Due to the decoupling and the reference to a common master axis, offset values relative to the master axis can be set both for the drives of the printing units and for the folder and can be predetermined in an advantageous embodiment for a specific production (web guide). The signals for further units can be freely parameterized.

It is advantageous in one embodiment, the temporal change of the Leitachsposition directly in the Leitachsposition leading signal line at a suitable location, eg. B. near the unit, tap and convert accordingly by means of the circuit. In another embodiment, the drive control or a computing and data processing unit connected to it carries out the conversion of the time change into a pulse sequence, for example, in a master control position. B. based on a map.

It is advantageous embodiment, wherein each rotational drive of the printing units (at least the drives of the independently driven cylinder cylinders other form cylinders) and the folding apparatus an offset value with respect to the leading axis can be set or predetermined. These offset values are preferably set in the respective drive controller of the drive or stored there as an offset. The specification of a certain offset value can, for. B. entered or changed in a control room and / or stored there for a specific production and retrieved accordingly and then the drive controllers or subordinate drive controls are transmitted.

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

Show it:

Figure 5 is a schematic representation of the master axis for the relative position of drives and the circuit during operation.

6 is an exemplary illustration of a set of pulse trains.

A processing machine for web-like materials, for. B. a printing press, in particular a web-fed rotary printing press, has a plurality of mechanically independently driven by a respective drive motor M units 01; 02; 03; 04; 06; 07 on. These independently driven units 01; 02; 03; 04; 06, 07 can z. B. directly or indirectly with a printing press passing through the web, z. As printing substrate, work together and must therefore be aligned in their relative position to the web or each other. Such units 01; 02; 03; 04; 06; 07 may be printing towers 01, individual printing units 02, individual printing units 03 or individual cylinders 04, in particular individual forme cylinders 04, of printing units 03. Likewise, such a unit z. B. a further processing of the web after printing unit 06, in particular a folder 06, or z. B. Perforiereinrichtungen, punching, collecting devices, cutting devices, etc. represent. Furthermore, such an independently driven unit can also have one or more guide elements 07, such as Σ. B. draw rollers, Skipslitter, register rollers, etc., be.

Fig. 1 shows three such mechanically independently driven by drive motors M units 01; 02, 03; 04; 06; 07. The two units shown on the left

For example, printing towers 01, printing units 02, printing units 03 or cylinders 04 can be. The middle or a further unit, not shown, but may also be a guide element 07. The right unit represents z. B. a further processing unit 06, in particular the folder 06 is.

The drive motors M each have a drive 08 with drive control, which in each case via at least one signal line 09 with each other and with a computing and data processing unit 11, z. B. a computer 11, are connected. The computing and data processing unit 11 may additionally comprise an operating unit 10 or with an operating unit 10, for. B. a control room 10, are in communication. The drives 08 (or controller 08) can in principle (not shown) in series directly in ring or bus structure or as shown in a tree structure by signal lines 12 to be connected to the signal line 09.

The at least one signal line 09 carries signals of a Leitachsposition Φ, which by a computing unit 13, z. B. a higher-level drive control 13, is specified. The signal line 09 together with the arithmetic unit 13, the so-called virtual master axis a (electronic wave) for the units connected to it) 01; 02; 03; 04; 06; 07, at which the units 01, 02; 03; 04; 06; 07 in their position or position. This Leitachsposition is passed to the drives 08 as a default (reference variable).

The computing and data processing unit 11 supplies specifications for the desired production speed to the higher-level drive control 13, and is thus connected to the drives 08 via the higher-level drive control 13, the signal line 09 (cross-communication) and the signal lines 12.

Each of the regulators 08 is a specific offset ΔΦ "z. B. angle offset .DELTA.Φ "predetermined, which a permanent but changeable shift relative to the

Defines Leitachsposition Φ. This offset ΔΦi? is z. B. directly on the controller 08 and / or via computing and data processing unit 11 entered and / or stored for specific operating situations, in particular specific web guides in a memory in the computing and data processing unit 11 and retrievable. If the signal line 09 is designed accordingly, for example as a broadband bus or broadband network, then the information about the respectively predetermined and fixed offset ΔΦi and the "rotating" Leitachsposition Φ can possibly take place via the common signal line 09. The signal line 09 can also be additional each be connected to a control system 24, which, for example, the different of the drive motors M actuators and drives of the printing units 02 or printing units 03 or folders 06, z., Color supply, positioning movements of rollers and / or cylinders, dampening, positions, etc. controls and / or regulates (connection shown in dashed lines).

The respective offset ΔΦi? is z. B. transferred before the start of production by the control room 10 or by the computing and data processing unit 11 to the drives 08 and stored there. In an advantageous embodiment, the offset ΔΦi can be varied during operation or production at the drive 08 itself, but in particular via the computing and data processing unit 11.

The offset values ΔΦi ?? for the various drives 08 can also be stored in the parent drive controller 13 in a variant. In this case, each drive receives 08 via the signal lines 09; 12 (or in series: only 09) as a specification the sum of the rotating Leitachspositioπ Φ and the specific, stored offset value ΔΦi of the respective drive 08th

So follow all the drives 08, for example, the drives 08 of the first two z. B. executed as printing towers 01 units and the drive 08 of the running as a folder 06 unit each of the rotating Leitachsposition Φ from the parent drive control 13, each with a fixed offset values .DELTA..phi.i relative to the absolute

Position of the master axis position Φ. The drive control 13 predetermining the Leitachsposition Φ thus acts as a master substantially independent of the units for all drives 08 coupled to this leading axle a.

With the virtual lead a (electronic wave) is now a circuit 15 in connection, of which one or more clock-shaped output signals l (t), z. B. in the form of pulse trains l (t), can be given to drives further units 19. The circuit 15, z. B. formed as an emulator, the rotating Leitachsposition Φ, ie the time-varying date for the angular position, converts into a pulse train. The circuit 15, as shown in Fig. 1, at its input from the drive controller 13 or the computing and data processing unit 11 obtain current values on the Leitachsposition Φ and convert them into digital and / or analog pulse trains l (t) and in an output output. Such pulse trains I (t) are shown schematically in FIG. A pulse train I (t) can also, as shown in FIG. 6, comprise a set of correlated pulse trains I (t) which, in their entirety, indicate the direction of a movement, increase safety and possibly define a zero point. For example, the output signal I (t) has a pulse sequence I _A (t) and its inversion, and a pulse train I _B (t) with a time offset and its inversion. In addition, the output signal receives a signal l _c (t) to identify a zero point.

Different units 19 and / or different manufacturers now make pulse sequences l (t) with different number of pulses per revolution n / 2π or periods with different period lengths τ and / or different amplitudes I and / or different composition of a set of pulse trains l _n ( t) and / or the presence of a zero point "0." The circuit 15 now has adjustment possibilities for one or more of the mentioned parameters n / 2π, τ, I, l _π (t), "0". This can take place via an interface by means of a PC, by means of a so-called jumper box or else via the computing and data processing unit 11. At least that's what the

Circuit 15 a possibility of adaptation (or possibility for parameterization) of the incremental resolution between the rotating master axis a; b and an angular position sensor of an on the circuit 15 to be controlled unit 19 and its drive on. This parameterization can consist, for example, in the specification of a resolution ratio, the specification of one or both values of the leading axis or aggregate resolution. Here is thus adjustable whether an angular position sensor of the unit 19 and its drive motor with, for example, 1024 increments per revolution or a different number n, such. B. 512 or 4084, is executed. Or, for example, a factor is indicated between the number of these increments and that on which the master axis is based. In an advantageous further development, the circuit 15 has a plurality of subcircuits with parameters n / 2π, τ, I, l _π (t), "0" and several outputs which can be parameterized in each case In this way, pulse sequences l (t) of one or more fictitious encoders are tailored for the drives of units 19 can be generated.

In contrast to FIG. 1, the conversion of the Leitachsposition Φ in a first pulse train l ₀ (t) with a fixed number of pulses or in the drive control 13, or a circuit implemented there 20, for example, a map, takes place in FIG Voltage per revolution π / 2re and shape, which is supplied to the input of the circuit 15. In circuit 15, based on the present parameters or parameter sets n / 2π, τ, I, I _n (t), "0", the output signal I (I) or the output signals I (t) are generated and sent to the unit 19 or are fed to the respective units 19. As indicated in Fig. 2, these can each be individually parameterized.

For the transmission of the respective offset ΔΦ, (and possibly other relevant data), in contrast to FIG. 1 in FIG. 2, a signal line 14 different from the signal line 09 is provided. Furthermore, for the connection between the signal line 09 and the signal line 12 each have a communication node 17, z. B. a subordinate drive control 17, is provided.

The arithmetic unit 13 for the specification of the Leitachsposition Φ is z. B. connected via the signal line 14 to the computing and data processing unit 11, from which, for example, it again receives specifications in terms of production speed or current target speed. The respective current Leitachsposition Φ is now specified by the parent drive controller 13 and fed into the signal line 09. From there, the information about the circulating Leitachsposition Φ is in each case via the communication node 17, given to the signal line 12 and there fed directly to the relevant for the current production drives 08. A communication node 17 may, as shown in Fig. 2, via the signal line 12, z. As a network 12 in ring or bus topology, with several, each driven by a drive motor M subordinate units such. B. printing units 02, printing units 03 or cylinders 04, be connected. The subordinate units taken together in this way via a communication node 17 are referred to below as group 18 of units or assemblies driven mechanically independently of each other. The communication node 17 in this case z. B. the Leitachsposition Φ from the signal line 09 to the drives 08 all (involved in the production) downstream units, z. As printing units 02 or printing units 03, this group 18 on.

The middle unit represents in the example of FIG. 2 such a group 18 of several subunits, e.g. B. two printing units 02, two printing units 03 or two guide elements 07 etc., whose drives are both 08 via the communication node 17 the Leitachsposition Φ.

In a first embodiment, the transfer of the production-specific offset values ΔΦi from the computing and data processing unit 11 or from the control center 10 to the individual drives 08 of the units takes place, where they are stored and further processed together with the Leitachsposition Φ. The transmission takes place here z. B.

in tree structure of the signal line 14 via a common signal line 16 per unit (or star-shaped over several separate signal lines 16 per unit) to the drives 08 out (solid lines).

In a second embodiment (dashed), the transmission of the offset ΔΦ, from the signal line 14 via logical connections 16 'directly or indirectly to the respective communication node 17. The physical execution of the logical connections 16' can directly or indirectly via other connections such as Bus Coupler, Bridges etc., or z. Example, via a in Fig. 1 or 3 shown control system 24, take place. The signal line (s) 16 can be omitted here. In a first variant of this embodiment, the specific offset ΔΦi is supplied from the communication node 17 only via the signal line 12 to the corresponding drive 08 and stored there.

In a second, advantageous variant of the communication node 17 is designed as a subordinate drive control 17 with a memory and its own intelligence in such a way that there the predetermined for the associated drives 08 and the specific production offset values .DELTA.Φi are stored, and that at the production participating drives 08 each addressed to this specific Leitachspositionen ι '(Φ |' = Φ + ΔΦi), z. B. are supplied as a desired angular position Φι 'by the subordinate drive control 17. The given context is intended to clarify here and in the following only the principle. Of course, when following the specific Leitachsposition Φι 'the extent of the driven units etc. to be considered, so that a real connection z. B. has further aggregate-specific factors.

The computing and data processing unit 11 is thus on the one hand via the parent drive controller 13, the signal line 09 (cross-communication), the respective communication node 17 and the signal lines 12, z. Buses 12, in connection with the drives 08. Also information about the configuration (coupling

of printing units 02 and / or printing units 03) or the common production speed can be exchanged in this way.

The computing and data processing unit 11 superordinate drive control 13 is to transmit the information to the specific offset ΔΦ, as described above either via the signal line 14 and the signal lines 16 or via the signal line 14, the logical connection 16 ', the communication node 17 and the signal lines 12 with the corresponding drives 08 in conjunction.

In the embodiment according to FIG. 2, the drive motors M of the group 18 are connected to one another and to the subordinate control 17. The subordinate controls 1 of the groups 18 or units are connected to one another via at least one signal line 09 and to the superordinate drive control 13. In addition, here the computing and data processing unit 11 is connected to the drives 08 or the communication node 17 for the transmission of the specific offset values ΔΦi via at least one signal line 14.

The signal line 09 is in an advantageous embodiment as a real-time capable compound 09 with a fixed time frame for real-time data and deterministic Zβitvβrhalten, z. B. as Arcnet trained. The connection 09 may additionally comprise a channel in which, for example, non real-time-relevant data, such. B. the transmission of the specific offset values ΔΦi according to the embodiment of FIG. 1 and / or information about the configuration, production speed, etc. according to the embodiment of FIG. 1 are transmitted.

The signal line 12 is in an advantageous embodiment as a real-time connection 12 with a fixed time frame for real-time data and deterministic timing, z. B. as Arcnet executed. The connection 12 may additionally have a channel in which, for example, non-real-time-relevant data, such. B. the transmission of the

Offset ΔΦi and / or information about the configuration, production speed, etc. are transmitted.

The signal line 14 and 16 is preferably formed as a network 14, 16 or as part of a network 14, 16. This network 14, 16 can again in an advantageous embodiment as network 14, 16 according to a deterministic access method, for. B. as Arcnet, work. However, the network 14, 16 can also be used as a fast network 14, 16 with stochastic access behavior, e.g. B. as Ethernet, be executed. However, data transmission should be possible at least in half-duplex mode.

3 shows an exemplary embodiment, wherein the virtual master axis is specified as a so-called master by one of the previously "subordinate" drive controllers 17. This is, for example, the drive controllers 17 of the folder 06. Again, as shown in FIG In a variant shown in dashed lines, a converted, defined pulse sequence I ₀ (t) is already supplied to the input of the circuit 15, which has been correspondingly generated in the drive control.

However, the Leitachsposition Φ or the converted pulses can also from other points of the virtual leading axis a; b or another drive control 1 of the circuit 15 are supplied.

4 shows an example of the drive of a printing machine with a plurality of, here three printing towers 01, which each have a plurality of printing units 03, here double printing units 03. The printing units 03 of a printing tower 01 together with their drives 08 and the motors M a group 18, in particular a pressure point group 18, which is connected via the subordinate drive control 17 of this group 18 to the signal line 09. However, the drive control 13 can also subgroups 02 of printing units 03, z. B. printing units 02, or other divisions associated with

Manage drives 08. With this signal line 09 are also further, own subordinate drive control 17 having units, for. B. one or more vanes 07 and / or one or more folders 06 connected. The signal line 09 is here advantageously designed in ring topology, in particular as a double ring, and has one or more of the properties mentioned above for FIG. 2.

In FIG. 4, a circuit 15 is in each case connected to a superordinate drive control 13, from which it connects the master axis position .phi.a; Φb or already receives the pulse sequence l ₀ (t). It is also possible to connect a circuit 15 to the common signal line 09, the circuit 15 (or its individual subordinate circuits for different outputs) then the one or the other leading axis a; b is assignable. This can then also be done via a parameterization for the individual output or the individual outputs.

The signal line 09 is connected to a plurality of, here two, higher-level drive controllers 13, which in each case different signals of a respective Leitachsposition Φ a; Φb a master axis a; b can feed into the signal line 09. This is advantageous, for example, if the printing machine or its printing towers 01 and / or printing units 02 and / or printing units 03 and the associated folding units 06 and guide elements 07 have a plurality of sections 21, 21; 22 should be assignable. However, productions and web guides may exceed the section separation indicated in FIG. 4 by a dashed line and from printing units 03 of one, in printing units 03 of the other and / or the folding apparatus 06 of the other section 21; 22 are performed. The individual printing towers 01 can be assigned, for example, to different folders 06. Even within a printing tower 01 are subgroups, z. As printing units 03, different webs with different web guides assignable, which can be performed on a common or even on different folders 06. The sections 21; 22 are logically not to be understood as rigid units.

The higher-level drive controllers 13 obtain their specifications regarding the starting point and production speeds of the respective section 21; 22 and / or web guide from a respective associated computing and data processing unit 11, which in turn are connected to at least one control station 10. In an advantageous embodiment, the two computing and data processing units 11 via the signal line 14 with each other and with another signal line 23, z. As network 23, which connects several, here two, control rooms 10 together. This network 23 can be implemented in an advantageous embodiment as a fast network 23 for a stochastic access method, for. B. as Ethernet, work.

The relevant for the individual drives 08 offset values Δ i are supplied for the beireffende production of the computing and data processing unit 11 and the computing and data processing units 11 via the signal line 14 to the respective drive 08 associated subordinate drive controls 1 and in an advantageous embodiment as to Fig. 2 described there stored and with the Leitachsposition Φa; Φb processed to the Leitachspositionen φ '. Are subgroups, z. B. printing units 03, a group 18, z. B. a printing tower 01, two different lanes, so the subordinate Antriebsssleuerung 17 each processed for the respective drive 08 associated Leitachsposition Φa; Φb of the leading axis a or b, depending on the affiliation of the relevant printing point to one or the other web, with the predetermined for this web guide offset value ΔΦi.

However, the transmission to the subordinate drive controllers 17 in this example does not take place directly, but rather via a control system 24, which has the respective group 18 or the unit having its own subordinate drive control 1, for example a control unit. B. folder 06, is assigned. The control system 24 controls and / or regulates, for example, the different of the drive motors M actuators and drives of the printing units 02 and groups of printing groups 18 and Druckwerke 03 bzw.

Folders 06, z. As ink supply, positioning movements of rollers and / or cylinders, dampening, positions, etc. The control system 24 has one or more (in particular programmable logic controller) 26. This control unit 26 is connected to the subordinate drive control 17 via a signal line 27. In the case of a plurality of control units 26, these are also interconnected by the signal line 27.

The control system 24 and its control unit (s) 26 is / are in an advantageous embodiment by couplers, not shown, for. B. Bus coupler, releasably connected to the signal line 14. As a result, the group 18 can in principle be operated by itself, with the control of the drives 08 taking place via the line of the subordinate drive control 17 with signal line 12 and the control of the further functions of the group 18 via the line of the control system 24. Setpoints as well as actual values and deviations can be switched on or off via the coupler. The subordinate drive control 17 assumes in this case the specification of a Leitachsposition Φ. For this reason and for reasons of redundancy, it is advantageous if all subordinate drive controllers 17 are designed with the possibility of generating and specifying a Leitachsposition Φ.

The offset values ΔΦ, are thus supplied in the embodiment of FIG. 4 from the signal line 14 via the respective control system 24 of the relevant subordinate drive control 17. As described in the exemplary embodiment according to FIG. 2, the offset values ΔΦ | alternatively be given from there to the drives 08 and stored and processed there.

In the embodiments of FIGS. 2 and 4, the higher-level drive control 13 can be omitted if z. B. one or more groups 18 or one of its own subordinate drive control 17 having units (eg folder 06) has a subordinate drive control 17. The virtual

Leading axis or Leitachsposition Φ is then z. B. of one of the drive controls 17 can be specified. In this case, the circuit 15 again receives its input signal (Leitachsposition Φ or converted pulse train l ₀ (t)) either from the signal line 09 or from the respective drive control 17th

In the described embodiments, at least one Leitachsposition Φ; .phi.a; Φb by at least one drive controller 13; 17 or a unit specified at which or at which the drives 08 of the various mechanically independently driven units are oriented in their position. Each of these drives 08 is a specific offset values ΔΦ, assignable, each of which the relative target position to Leitachsposition Φ; .phi.a; Φb of the assigned master axis a; b expresses. Thus, for example, for a specific production of all mechanically independent drives 08 of the printing towers 01 (or printing units 02 and printing units 03) and the associated drive 08 of the folding apparatus 06 and possibly guide devices 07 each have specific offset values ΔΦ | in relation to the relevant production axis, a; b assigned. References the leading axis a; b its Leitachsposition Φ; .phi.a; Φb initially or in the further course of one of the units, for. B. from the folder 06, the remaining units a specific offset values ΔΦi is assigned.

These offset values ΔΦi are based essentially on purely geometric conditions. For one thing, they are of the chosen course guidance, d. H. depends on the railway route between the individual units. On the other hand, they can depend on a random or selected zero position of the individual drive 08. The latter is omitted for the individual drive 08 when its defined zero position with the zero position of the leading axis a; b coincides or the leading axis a; b refers to their location from this unit.

The z. B. in mm determined value for the offset ΔΦi of the individual drives 08 of

Printing units 03 and the folding apparatus 06 are stored at the control station 10 or in the computing and data processing unit 11. In addition, it is advantageous if this set of offset values ΔΦi (eg in mm) are stored with reference to data for the specific pathway or vice versa.

For automation, the manually determined offset values .DELTA..phi.i can be stored as a function of the web guide via the control station 10 and retrieved upon repetition of this production and again via the above-mentioned. Way to the drives 08 are forwarded.

If the printing machine or the relevant unit is now driven, then follow with the leading axis a; b coupled via the angular positions drives 08 with its zero position plus added offset ΔΦi the Leitachsposition Φ; .phi.a; Φb and thus always have the right position. The not directly coupled drives 19, the converted pulse sequence l (t) from the circuit 15 is supplied.

Fig. 5 illustrates this situation schematically, wherein the printing unit 03 and the folder 06 common master axis a; b the Leitachsposition Φ; .phi.a; Φb, the printing unit 03 or the driving drive 08 driving the position Φ + ΔΦ _D j, ie the sum of the Leitachsposition Φ; .phi.a; Φb and the offset ΔΦ _DW J specific to the jth printing unit 03 (in the case of this web guide), and the folding apparatus 06 or its drive 08 the position Φ + ΔΦF _A I, ie the sum of the master axis position Φ; .phi.a; Φb and the offset ΔΦ _FAk (for this web guide) specific to the kth folder 06. As explained above, the relationships represent the simplified principle without any further unit-specific factors. The sounding 15 obtains either the lead axis position Φ as explained above; .phi.a; Φb or an already converted pulse sequence l ₀ (t) and generates at its output or its outputs corresponding output signals l (t) for the unit 19 and the units 19 with appropriate parameterization.

In an advantageous embodiment, a correction of the respective offset .DELTA..phi.i and / or a parameterization is also possible in the continuous printing or while the machine is running at the control station 10 or / and the computing and data processing unit 11 or at the circuit 15.
