Abstract
SUMMARY
A printing machine (1) with at least one printing unit (4-7) is proposed, featuring a number of sensors for monitoring the printing procedure and a number of control elements for setting, for example, the ink profile, the fluid profile, the paper feed and other similar functions. The entire processing of the sensor signals, their interlinking and the output of control signals, as well as the output of display signals takes place in an overall electronic control (11) which is linked via data lines (21,22) with the printing machine, or the sensors and the control elements in the printing machine (1).
Furthermore, assigned to the overall electronic control circuitry (11) are measuring devices such as a printing plate reader (12) or a quality monitor (13), whereby the measured signals are correspondingly processed also to facilitate setting of the printing machine. monitoring of the printing process and any interventions in the control of the printing machine which may be necessary are facilitated by a control desk (15) which is assigned to the overall electronic control circuitry (11) via a data line (26). The printing machine itself contains no additional electronic or electrical control devices but, apart from the sensors and control elements, only the displays and control facilities necessary for monitoring the printing procedure.

~ 8.04.1986 "Printin~ machine with at least one printin~ unit"
The invention refers to a printing machine with at least one printing unit, containing a number of adjusting elements and sensors.
From DE-AS 27 28 738, a printing machine is known which features several ink metering elements in the form of control elements arranged over the printing width and which can be set in coniunction with an adjustment device. The ink density produced on the printed sheet is scanned by means of suitable sensors and the setting of the ink metering elements is corrected after a set value/actual value comparison.
Furthermore, from DE-OS 28 30 085, a process is known for indicating the adiustment variables in printing machines, featuring on the printing machine zonal control elements for metering the ink and/or fluid feed and the adjustment variables are converted by sensory elements into display signal such as to indicate the set ink profile.
It is also known that printing machines, for example sheet offset printing machines, feature a further number of sensors, for instance, for monitoring the paper run or the paper feed and delivery or dampening solution application, while also having a further number of control elements for setting the register for instance.
In addition, control facilities are also necessary for the main drive and for auxiliary drives. The disadvantage in the case of the known versions is the decent.ral arrangement, i.e. distributed over the entire machine, of various electronic regulating and control devices. Each of these devices requires at least its own power supply and contains its own signal processing facilities (intelligence) with limi~ed processing options.
A further disadvantage is that the data processed in the individual electronic unit are not immediately available, or are interchangeable on data lines between each other or on a collective basis only with increased complexity.
In addition, due to the longer data lines, the data exchange rate is reduced and the susceptibility to inter-ference increased. Checking these individual electronic units also necessitates increased time requirements.
~8~)2~8 A--4~1 In accordance with the features of the main claim, the invention is based on the fact that a combined data processing and control device assigned to the printing machine is provided, with which the control and signal input and output of the functions and/or statuses of the printing machine, as well as the measuring devices and units which can be assigned to the printing machine are carried oùt.
An advantage of the invention is the entire processing of all sensor signals as well as the entire coordination of the adjustment signals by means of the data processing and control device, hereinafter also termed overall electronic control circuitry. In this way, for example, functions such as paper transport, paper feed and paper delivery, ink and dampening solution application, ink drying, powdering are controlled and displayed. The statuses of the machine or of the measuring devices and units, such as machine speed, inking-in and dampening of the plate cylinder, register position, functional standby of measuring instruments or quantities of auxiliary materials and others can be evaluated by the overall monitoring system as an indication for correct printing.
In addition, all data of the printing machine are avail-able and can be selected centrally. Furthermore, the entire machine control, which up until now was implemented by means of a contactor control system and which is known to feature confined linking options, can now be implemented by an overall control, making possible, due to the greater linking capacity, optimization of the printing process under various operating conditions. The data processing rate is increased due to the short data paths, at the same time, a higher degree of reliability with regard to interference is attained.
The above mentioned device, for example, consists of a number of individual computers which, under the control of at least one host computer, process the data supplied by the printing machine and generate control signals.
Furthermore, it is possible with the aid of this device to quickly indicate to the printer all data relevant for it, or the data necessary for optimizing the printing process.
A further advantage of the invention can be found in the fact that the data processing and control device can be designed on a universal basis as an overall electronic control, i.e. printing machines of different size or design can be controlled.
By arranging the data processing and control unit outside the printing machine, adaptation is rendered unnecessary of the individual controls to different components of the printing machine which up until now has been the case due to given constructional conditions.
In a further configuration of the invention, it is proposed to divide the data processing and control device into two units, whereby the first unit processes all the data necessary for ink control, such as ink application and register setting, while the remaining data are processed in the other unit. This offers the advantage that the ink control can be carried out precisely where a set value actual value comparison is possible between the printed product and the preset cr:iteria based on a sample sheet for instance.
A further configuration of the invention is achieved by specific arrangement of the data processing and cor.trol device. A host computer (several host computers operating in a compound system would also be possible) is linked with the individual computers via a common data bus. The task of the individual computers is to control or to monitor certain functions or statuses of the printing machine. Under certain circumstances, it would also be possible for one computer to take on the function of another An advantageous version of the invention envisages to connect an external data line to the data processing and control device, for instance, in order to enter via an external input unit preparatory measures such as determined ink profile, paper thickness, quantity and presettïng data of the printing machine. In addition, in conjunction with this external data line, data or diagnostic data can be selected from the device, for instance, by connecting a diagnostics facility or via telephone diagnostics, since all data are available in this device.
In a further version of the invention, it is proposed to produce in coniunction with sensors the input signals or at least certain input signals of the said device. In an alternative arrangement, booster amplifiers can be subsequently connected to the sensors in order to boots a weak signal to a level not subiect to interference.
In accordance with a further configuration, control elements are actuated directly by the overall electronic control with low power. Suitable control elements, i.e.
also switched with low power, are however n~cessary for .28~21~3 ~~~ A-491 , - 4 -j this purpose. This offers the advantage that adaptation ¦ of the output signals of the overall electronic circuitry to the control elements with high input power is rendered unnecessary. In addition~ the application of low power makes it possible to use ribbon cables to transmit this _~ power, offering the known advantages such as low space requirements and easy handling.
The displays/indicators and the input facilities or control elements of the device are combined in accordance with one version of the invention in a control and monitoring desk. This desk can form one unit with the data processing and control device, however, it is also possible to arrange this desk separated from the said device and to provide a link to the device by means of cables.
A po~der unit can also be connected for example via the data processing and control device. Although it features an internal control, the device also supplies it with data or signals, e.g. the machine speed or the ink properties.
Further advantageous configurations of the invention are included in the description and in the subclaims.
The inven~ion is explained in more detail in the following in the form of two version examples based on drawings.
Fig. 1 shows the schematic layout of a printing machine with an assigned data processing and control device Fig. 2 shows a version of the data processing and control device shown in Fig. 1.
The printing machine shown in Fig. 1, a sheet offset printing machine 1, consists of several printing units 4-7, a sheet feed 2, a sheet delivery 3 and a drive motor ¦
8. Operation is enabled by a control panel 9 of the sheet feeder 2. Furthermore, mounted on the sheet delivery 3 is a control panel 10, on which, for instance, the machine speed is indicated, while also enabling interventions in the machine control. All sensory signals, such as set ink profile, fluid profile, sheet run, register setting at the individual components of the printing machine such as printing units, sheet feed and delivery, are directed via a signal line data processing facility 21 to a data processing and control device of central design as an overall electronic unit 11. At the same time, indicator ,1 ` - ~LZ~ 8 A-4gl signals necessary for monitoring directly on the printing machine are also directed via this signal line from the overall electronic unit 11 to the individual components of the printir.g machine. Both actuating signals for the r ~~ electrical control elements within the components of the printing machine as well as the drive power for the main and auxiliary drives are fed to the prin-ting machine via a signal line power control 22 from the electronic power supply circuitry 14 located within the overall electronic circuitry 11. The overall electronic circuitry 11 is also linked via a data line 25 to a printing plate reader 24 and via a data line 24 to a quality monitor 13 which carries out densitometric evaluation of the printed sheet. The overall electronic circuitry 11 is connected to a control desk 15 via a data line 26. This control desk 15 contains in a first section input facilities and a display 17 for control of the inking device 19 and in a second section input elements and a display 18 for machine control 16. It is, of course, also possible to combine both sections and to jointly carry out the machine and inking control in one display and one input control desk. As shown in the figure, the printing machine features no additional or data processing circuits or devices; the great number of electrical circuits which were previously distributed over the entire printing machine are now combined within the overall electronic circuitry 11. This electronic control 11 is not only a simply combination of previously used components, but rather it also enables as the result of the interlinking of these components, optimized regula-tion and control of the printing process. In addition, an ~xternal data line 20 is provided which can be used, for example, to feed data to the printing machine from a position responsible for preparing operation. For instance, all settings for the control elements to preset the printing machine can be transferred via this data line. In the same way, order-specific data such as the number of prints to be produced, can be fed to the printing machine or the control desk 15. Via this external data line 20, it is also possible to output data specific to the printing machine. To facilitate prepara-tion of a printing process for example, specific inking-in of the inking units can be carried out in conjunction with the overall electronic control. It can also be used to check the function of the control elements and sensors. Furthermore, it is also possible with the aid of the overall electronic circuitry 11 to monitor the wear of susceptible parts and components of the printing machine and to provide warning signals when certain limit values are exceeded.

¦ J A-491 Fig. 2 shows a variation of the version example in accordance with Fig. 1 with respect to the desi~n of the overall electronic circuitry. This version of course also contains the said advantages.
The design of the printing machine corresponds to that shown in Fig. 1. The same parts are assigned the same reference numbers.
The overall electronic control 11 is divided into a first unit which consists of a processing block 28 with integrated power electronics 14 and into a second unit which is in part arranged in the control desk 15. This second unit only contains the inking control and register setting and is directly linked to the printing units 4-7 via the signal line inking control register 23. This second unit is of course also linked with the first unit and the processing block 28 to combine the data via data line 26. In this example, the printing plates reader 12 and the quality monitor 13 are connected directly via the data lines 24,25 with this unit for inking control since both the result of the printing plate reader 12 as well as the result of the quality monitor 13 have a direct effect on the presetting or correction of the ink profile. The machine control section 16 of the control desk 15 serves as an input and display panel for all functions performed in the processing block 28, or to display the statuses of the printing machine which do not concern the inking control. The signal line data processing 21 and the signal line power control 22 are connected to the processing block 28. In the same way, the external data line 20 is connected to the processing block 28, of course making it possible to monitor or influence the inking control via this external data line 20.
The structure of the overall electronic control 11 also enables connection of several printing machines of similar design. The individual printing machines can be selected separately, processing and output of data from and to the printing machines can take place in any arbitrary mode of operation, where priority assessment of data is also possible.
