Definitions
- the invention relates to a shaftless rotary printing machine according to the preamble of claim 1.
- a newspaper offset rotary machine hereinafter referred to as a rotary printing press, generally consists of several producing units - called rotary - which can work simultaneously and independently of one another (maximum 10).
- Each producing unit consists among other things of roller carriers for the paper rolls, pull rollers for pulling the paper web in and out of the printing towers, printing points, which are summarized as U- (two printing points), Y- (three printing points) or H printing units (four pressure points) work in one or more printing towers, auxiliary drives at the pressure points (e.g. for plate change) and the folder.
- a rotation is generally controlled via several PLC systems, which in turn are managed by higher-level control centers.
- the systems are networked with one another via serial bus systems.
- a pressure point essentially consists of a rubber cylinder, a plate cylinder and a dyeing and dampening unit. One color can be printed on one side with each printing point. All printing points that work on a folder, that is, whose printed paper webs are guided on a folder, belong to a rotation.
- the printing points in a machine are housed in printing towers; a maximum of eight pressure points in a tower (eight-high tower) - in the future also max. ten pressure points in one tower (Tens tower) aimed -. Up to twelve eight-high towers can work on one folder in one rotation.
- FIG. 1 shows a conventional rotary printing machine with waves.
- One, in some cases also two mechanical longitudinal shafts 2, which are coupled via gears 4 (eg bevel gear), as well as mechanical vertical shafts 6 in the pressure towers 8, 10, 12 enable the synchronous angle by rigid coupling within one rotation - All printing points 14 run in sync with one another and with a folder 16 or 18. Synchronicity is only ever necessary within one rotation.
- the longitudinal shaft 2 runs through the entire machine and is usually driven by several main motors for reasons of torque distribution and flexibility.
- the vertical shafts 6 or the printing units 20 are coupled in and out via mechanical couplings 22.
- additional separating couplings 24 must be installed in the longitudinal shaft 2 if individual printing towers 8 or 10 or 12 are to work in different rotations.
- Printing tower 8 and printing tower 10 can operate two rotations independently of one another - printing tower 8 on folder 16 and printing tower 10 and 12 on folder 18.
- the setpoints for converters and their synchronization are specified via a very fast, serial fieldbus system.
- the ⁇ ERCOS bus system is mainly used for this. This history can be found in the essay “Many attempts preceded the longitudinal shaftless machine drive", printed in the magazine “PRINT”, volume 39, 1994.
- a rotary printing press is known from EP 0 567 741 A1, in which the cylinders and at least one folder are driven directly.
- Several drives of the cylinders and their drive controllers are combined into pressure point groups which can be assigned to a paper web.
- the pressure point groups are interconnected with the folder and with an operating and data processing unit via a data bus.
- the individual drives of the cylinders and their drive controllers are connected via a fast bus system.
- the pressure point groups get their position difference directly from the folder.
- the higher-level control system is only responsible for the specification of setpoints, setpoint deviations and the processing of actual values.
- the superordinate control system is connected to a pressure point group by means of the data bus, by means of a drive system and by means of a fast bus system.
- the positioning of the individual drives in relation to the folder and relative to one another is regulated in the drive system.
- the data and commands coming from the higher-level control system are adapted to the form required for the drive controller in the drive system.
- Global control via the data bus is limited to the specification of setpoints, setpoint deviations and actual values as well as setpoint control.
- the parameters for the fine adjustment of the individual drives are calculated separately in each pressure point group in the drive system.
- the folder works by means of a control / parameterization bus signals for control, diagnosis and parameterization and by means of the synchronization bus only information that is intended to ensure the synchronous angular synchronism of the drives in one rotation is transmitted, the drive of each printing point receives all information that are necessary to operate the printing point.
- Each drive can thus be regarded as the smallest complete unit of a shaftless rotary printing press, which can be put together for any rotation depending on a product to be printed.
- the use of two separate buses running in parallel maintains the basic concept of a rotary machine according to FIG. 1, one of the two buses, namely the fast bus, replacing the mechanical shafts by implementing an electrical shaft.
- the information guidance for controlling the drives of such a rotary printing press according to FIG. 1 is retained.
- the flexible assignment of the printing points to several folding devices in a rotary printing press according to FIG. 1 is determined exclusively by the mechanics, with each gain in flexibility having to be bought through an additional outlay on mechanical components.
- the flexible assignment of the printing order of the printing points to several folding devices is no longer disturbed, since each drive continues to receive the information for its operation by means of the control / parameterization bus and can easily be integrated into a drive concept by means of the synchronization bus.
- the basis of this drive concept according to the invention is the strict separation between control / parameterization functionality and the function of the electrical shaft on the drive. In practice, this has the consequence that a controller can access the drive via a control / parameterization bus for control / parameterization tasks.
- a device for generating a setpoint and a synchronization signal for the realization of the electrical shaft which device specifies the timing and the setpoints for synchronous angular synchronism of the drives via a synchronization bus.
- the electrical shaft thus replaces the function of the synchronization of pressure points via the mechanics.
- FIG. 1 shows a conventional rotary printing machine provided with shafts
- FIG. 2 shows a shaftless rotary printing press with an electrical shaft
- FIG. 3 shows the drive concept according to the invention in simplified form
- FIG. 4 shows a redundantly designed embodiment of the drive concept according to the invention, wherein two connection examples of a bus switch are shown in FIG.
- FIG. 2 shows a shaftless rotary printing press, consisting of two folders 16 and 18 and three printing towers 8, 10 and 12. These three printing towers 8, 10 and 12 each have two H printing units 20, each of four printing units ⁇ 14 exist.
- Each printing point 14 consists essentially of a rubber cylinder 28, a plate cylinder 30 and a dyeing and dampening unit. With each printing point 14, a color can be printed on one page. All printing points 14 which work on a folder 16 or 18, i.e. their printed paper webs 32 and 34 or 36, 38 and 40 are fed onto the folder 16 or 18, belong to one rotation.
- a maximum of twelve printing towers 8, 10 and 12, each with a maximum of eight printing points 14, can work on a folder 16 or 18 in one rotation.
- Each printing point 14 in the rotary printing press is driven directly by a drive unit consisting of a three-phase motor with a corresponding converter.
- the same also applies to the drive of the folders 16 and 18.
- the mechanical coupling between the three-phase motor and the rubber cylinder 28 can be a direct coupling or a coupling via a toothed belt or a gear. A decision about the mechanical coupling essentially depends on the required dynamics of the drive.
- the angular synchronism control of the pressure points 14 to each other or to the folder 16 or 18 takes place in each converter. Speed and torque control is subordinate to this.
- the sine / cosine signals that are read are used in a detection circuit in the converter to approximately 4 million increments per revolution and are made available to the angular synchronism control as a high-resolution actual value.
- a second encoder integrated in the motor is used for the speed and torque control.
- a control / parameterization bus 42 and a synchronization bus 44 are provided in the shaftless rotary printing machine according to FIG. 2, of which only the synchronization bus 44 is shown in this illustration is.
- Each drive of a pressure point 14 is linked to the synchronization bus 44.
- the electric motor M of the drive of a pressure point is shown.
- each drive can be combined with any other drive of the drive concept of the rotary printing press by means of the synchronizing bus 44 to form any rotation that is on a folder 16 or 18 operates, each of these drives being parameterized, controlled and monitored by means of the control / parameterization bus 42.
- the drive concept according to the invention is shown in simplified form in FIG.
- two drives are shown in more detail, which are connected on the one hand to the control / parameterization bus 42 and on the other hand to the synchronization bus 44.
- the drive comprises two bus interfaces 46 and 48 (FIG. 4) for the synchronization bus 44, a bus interface for the parameterization / control bus, a converter device with an integrated technology function, e.g. for angular synchronism, and the electric motor M, which can be, for example, an asynchronous motor or a servo motor.
- the synchronization bus 44 is designed as a ring bus and is connected to a device 50 for generating a setpoint and a synchronization signal.
- Control / parameterization bus 42 is connected to a controller 52. This control controls, parameterizes and diagnoses the drive in synchronous operation as well as in island operation.
- the device 50 which is superior to the drive units, and the controller 52 are integrated into the entire information exchange of the machine via a further serial bus system, which is often designed redundantly (system controller).
- system controller which is often designed redundantly (system controller).
- the synchronization of the individual drive units at the printing points 14 to one another or to the drive unit in the folder 16 or 18 takes place via the serial synchronizing bus 44.
- the synchronizing bus 44 functionally replaces the mechanical longitudinal and vertical shafts 2 and 6 of the machine.
- the device 50 specifies its individual position setpoint from each drive via the synchronization bus 44.
- the setpoint value consists of the angle value of a master pointer and, in addition, an offset angle that is individual for each drive. Furthermore, the processing of the angular synchronism, speed and torque control of each drive is synchronized to a common starting point via the synchronization bus 44 by means of a synchronization signal, that is to say a special telegram to all participants (broadcast). Through strict time-cyclic repetition of this synchronization signal, all drives of a rotation are synchronized with one another.
- the synchronization bus works according to the master-slave principle.
- a device 50 superordinate to the drive units is the master station of the synchronization bus 44 (single master).
- the drive units are the slave stations.
- the synchronization bus 44 is constructed as a ring bus by means of optical fibers.
- a maximum of 200 users can be connected to such a synchronization bus ring 54 or 56.
- the performance is designed so that 100 participants can be supplied with individual setpoints every two milliseconds.
- a device 50 is associated with each rotation in the machine, ie ultimately with each folder 16 or 18.
- the folder 16 or 18 is thus, as in the previous solution with mechanical shafts, the station to which the printing points 14 are synchronized.
- Drive units which are assigned to different devices 50 are not synchronized with one another.
- the basis of the electrical wave is the creation of a central rotating master pointer.
- an offset angle that is individual for each drive can be added to the leading pointer in the device 50.
- the current position of this angle value (master pointer plus offset angle) is transmitted at a certain point in time in the timing of the synchronization signal of the synchronization bus 44 as a setpoint to the corresponding drive via the synchronization bus 44.
- all drives are supplied with their individual angle value in one rotation.
- Each drive follows its individual angle setpoint in position and speed (angular synchronism control).
- the speed at which the master pointer rotates is determined from the specified web speed of the machine and the circumference of the pressure rollers.
- the offset angle for each drive is essentially determined from the registration control.
- the position of each rubber roller can be changed individually in relation to the other rubber rollers or the folder 16 or 18. This function eliminates the need for conventional registration rollers or register slides.
- the strictly time-equidistant synchronization signal is transmitted as a special telegram to all participants (broadcast).
- the time interval between two synchronization signals can be parameterized.
- the scan cycles of the inverters for angular synchronism, speed and torque control are synchronized with this synchronization signal.
- Each drive is controlled separately from the synchronization bus 44 via a second, serial bus system 42. From the control 52, one or more drives can be controlled, parameterized and controlled via the control / parameterization bus 42 be diagnosed.
- Open and standardized field buses such as PROFIBUS-DP or else company-specific bus systems, such as the USS protocol or ARCNET, can be used as bus systems for this control / parameterization bus 42.
- FIG. 4 shows a redundant embodiment of the drive concept of a shaftless rotary printing press according to the invention.
- the plurality of pressure points 14 are numbered consecutively in order to understand this redundant embodiment.
- Each printing point DS1, ..., DSn, DSn + i, ..., DSn + 4 has two interfaces 46 and 48 for the connection to the individual synchronization bus rings 54, 56 and 58.
- the pressure points DS1, ..., DSn + 2 are integrated in the synchronization bus ring 54, but of these pressure points DS1, ..., DSn + 2 the pressure points DSn + 1 and DSn + 2 are not for this synchronization bus ring 54 ⁇ activated.
- the activated bus points 46 and 48 are marked black, ie the assigned drive accepts the setpoint specification and the synchronization signal of the device 50.
- the pressure points DS3,..., DSn + 4 are integrated in the synchronization bus Rmg 56, but are of these pressure points DS3, ..., DSn + 4 the pressure points DS3, DSn and DSn + 4 are not activated for this synchronization bus Rmg 56.
- the synchronization bus ring 56 is not shown completely.
- the synchronization bus ring 58 is not shown completely.
- the pressure points DS1, ..., DSn work on the folder 16, whereas the pressure points DSn + 1, ..., DSn + 3 work on the folder 18.
- a device 50 for generating a desired value and a synchronization signal is assigned to each folder 16 and 18.
- the synchronization bus rings 54 and 56 are connected to the associated device 50 by means of a bus switch 60.
- the illustration of the bus switch 60 shows that its input IE is wired directly to output 3A and input 3E to output IA.
- the other inputs and outputs 2E, 4E and 2A, 4A are not wired together. With this number of inputs and outputs, 24 combinations can be created.
- the bus switch 60 is only required for the implementation of the redundancy requirements for newspaper presses.
- the main task of the bus switch 60 is to enable the synchronizing bus 44 to be routed so that a device 50 of one rotation can also be integrated in a synchronizing bus ring of another rotation in a simple manner.
- a bus switch 60 is always directly assigned to a device 50.
- FIGS. 4 and 5 show the principle of the flexible assignment of the drives and the interconnection of two separate synchronization bus rings 54 and 56 to form a single ring with a device 50.
- a printing point for example the printing point DS3 in FIG. 4, is synchronized to the folder 16 during production. Without mechanical intervention, there must be the possibility of integrating this drive into an adjacent rotation for another production.
- Each drive which is to run in angular synchronism with other drives via an electrical shaft, can be synchronized by two independent synchronization buses 44.
- each drive has two bus interfaces 46 and 48.
- This drive is integrated using the example of pressure point DS3. into the two synchronizing bus rings 54 and 56.
- the drive can thus either run synchronously on the folder 16 via the device 50 or it can work in the synchronizing bus ring 56 as part of the second rotation (synchronously on the folding device 18) .
- By parameterizing the drive it is determined from which device 50 the angle setpoint specification and synchronization takes place. With this mechanism, the machine operator can implement the assignment of a printing point to two folders 16 and 18 by simply changing the parameters on the drive.
- the bus switch 60 is a component of the synchronizing bush 44 for dividing the line routing of the optical waveguide ring 54 or 56.
- FIG. 5 shows two examples of the function of the switch 60.
- the bus switch 60 is always assigned directly to a device 50 of a folder 16 or 18.
- the solution principle is explained in the following example:
- the rotary printing mechanism consists of three folders, of which the two folders 16 and 18 are shown for the first and second rotation.
- the folder 16 fails in the first production.
- the second production is shut down.
- the two bus switches 60 are switched over to a different line routing.
- all drives that were previously in the two separate Synchroni ⁇ ierbu ⁇ rings 54 and 56 are combined in a ring 56.
- Production can now continue as an emergency operation.
- the failed folding apparatus 16 or 18 can also be detached by a stand-by folding apparatus.
- the synchronization bus ring 54 or 56 is placed by switching the switches 60 to a device of the stand-by apparatus.
