The control element for the servo drive Zi consists of a WL 66 circuit, a relay of the servo actuator 67, diodes 68-70, and switches 64 and 65.

The output of the scheme SHSh 66 control There is a relay of control screws 67 and output wire 33. In addition, the signal from the second input of the OR circuit through diode 68 goes to the output wire 30, the signal from the third input through isolation diode 70 to the output wire 30, and the signal from the fourth input through isolation diode 69 - to the output wire 29 of the program lock. The common control element 4 consists of switches 71 and 72 of the OR circuit 73 and relay 74. The switch 71 controls the first input of the OR circuit 73 and the output wire 30. The switch 72 controls the second input of the PC 73 circuit and the output wire 30. The relay 74 controls the input circuit wire 18. The device operates as follows. In the common control mode of operation, the common control element 4 is connected via wire 18. When the switches 71 and 72 are pressed, the wires 30 indicate the direction of movement of the adjusting screws of the paint unit to the central control unit. Simultaneously, all relays of the adjusting screws of the inking unit 67 are recorded through wire 28. If this happens, information about this also goes to the central control unit 1, which now controls the impulses of the pulse train 5 in accordance with the required direction of rotation. 12 is a matrix. - In the mode of operation of the general control, as a result of the washing of all the relays of the adjusting screws of the inking unit 67, all rows of the matrix (wires 33) are energized simultaneously. Through the wire 37, the amplified pulses now flow from the amplifiers 5 through the relay 12 to all the servomotors 13 of the corresponding section 6, selected with the help of the switch of the printing section 11. The control process lasts as long as one of the switches 71 and 72 is pressed.
    In operating modes 2-4, the operation of the central control unit 1 is determined directly by wires 19-21. Group control can be implemented by means of the servo drive controls 3, having pre-programmed the adjusting screws of the inking unit, which must be adjusted together. The adjusting screws of the inking unit are inserted into the system by pressing the corresponding switch 64 and are again switched off from the system by pressing the switch 65. This is possible due to the fact that wire 27 (pick-up wire) is fed in the group control mode of operation and, thus, the adjusting screws relay 67 can perform the memory function. As a result, the necessary rows of the matrix are again energized for switching relays (wires 33). The selection of printing units is no longer repeated, since it is carried out in all modes of operation in the same way as in mode of operation General regulation.
    By pressing one of the buttons of the common control element 4 again, similarly to the operating mode. General control, the process of screw control is introduced, which continues as long as the button is pressed.
    Operation mode Separate control is activated immediately after pressing one of the buttons of the servo drive control element 3, as a result of which the selected adjusting screw of the inking unit is affected (similar to the operating mode, general control and group control). The peculiarity of this is that only one row of the matrix can always be controlled. This is achieved by the function, wires 25 and 26 between the control unit 1 and the control elements of the servo drive 3.
    If not a single relay of the adjusting screw of the inking device 67 has yet been triggered, then wire 25 (connection wire) is energized. As soon as
    , the wire 29 to the control unit 1 received a message that one relay of the adjusting screw of the inking machine 67 was triggered, the wire 25 is disconnected, but the other relays 67 cannot be activated. This method is very easy to achieve locking between all screws, since the control unit is at least 3 orders of magnitude faster than the relay.
    The installation process continues as long as the button on the control element of the servo drive 3 is pressed. After the end of this, the wire 26 through the delay element 44 is briefly
    turns off, causing
    the relay of the adjusting screw of the inking device 67 is thrown.
    When operating modes General management. Group control, Separate control of wire 30 for all controls 3 and 4 accomplishes the task of transmitting information about the direction to central control unit 1. If both wires are energized at the same time, the installation does not occur (blocking the installation process). Through the wire 22 central adjustment device in
     the time of all installation processes transfers the number of permutation steps to block 8 with a digital indication 10. After the end of the adjustment process, the permutation steps are memorized
    n by indication.
    Only with the introduction of a new display process, it goes out first, before counting out the new steps of re-opening (with a sign). During this
     device operation time, independent. MO from the selected mode, the actual position of the adjusting screws of the inking unit can be read on the measuring unit 7 with its analogue measuring devices 75. The principle of measurement is based on the matrix circuit, while the wires 34 represent the rows of the adjusting screw of the inking unit, and
    S wire 39 is a column (printing units), with potentiometric measurement sensors position 14 included at the intersection of the line
    and column. The corresponding column is energized by switching the measuring supply voltage by means of the switch of the printing section 11. The mutual influence of the printing units on one another is eliminated by decoupling diodes of measured values 15.
    In the Measurement mode of operation, no adjustment process is possible, since the forcing of the permutation steps is blocked in the control unit 1.
    The locking described for the operation mode serves to indicate the position of any adjustment screw of the inking device on the digital display 10 ..
    By means of the control elements 3, the row is again selected, and by means of the switch 11 of the printing unit, the column of the digitally measured position of the adjusting screw of the inking unit is selected. The wire 19 records the switching relay 17. In this case, the digital display panel 10 is connected to the analog-to-digital converter 9, and the return wire of the relay 16 for the selection of measured parameters is connected to the potential of the housing, which is the condition of the current passage in these nodes, carried out later wires 33 (wires of lines). The measured value then arrives from one of the wires 34 and through the contact of one of the relay 16 to select the measured parameters is fed to the input of the analog-digital converter 9. When the switch 64 is pressed on control element 3, the measurement mode starts, and by pressing the switch 65, the measurement process ends.
    I
    The main unit of control unit 1 is a ring counter 40. Together with both OR 57 and 58 logic circuits OR 57 and 58, it produces a packet or sequence of pulses to control the stepping motors (servomotors) 13 n output wires 23, depending on which direction relay ( 46 or 47) worked.
    Each step of the servomotor consists of four separate states:
    012301 230
    About 000000
    00000 00
    000000 Oh
    0000000
    .00000
    0000
    О000 О
    00О 00
    Adjusting screws back
    By virtue of the dynamic memory element 45, all four states are allowed to pass before the installation process is completed. Thereby, an equal step length is achieved, with the result that all servomotors always occupy the same initial electrical position.
    To ensure this, a memory element 42 is also required, which must also remember the choice of direction when the wires 30 already have no signal, the AND logic circuits serve to block the directional choices between themselves. By means of the pulse sensor 43, the speed of the permutation is established under the operating modes General control, Group control.
    For operation mode Single control requires a slow installation speed. For this purpose, there is a delay element 44, which each time creates a certain interval between the steps of the permutation (which are always executed at a constant speed). By simultaneously pressing the buttons on the control element of the servo drive 3 and on the common control element 4, this delay element can, however, be rotated, and thus, in the Single control mode, control can be performed at a higher speed. After the permutation step has been completed, the reversible counter 41 receives, through both circuits, And 59 and 60, valid depending on the state of the memory element 42 as coincidence circuits, from the output of 4 ring counters, a positive or negative counting pulse. The dynamic memory element 45 triggers at the beginning of each permutation cycle, opens a clock input matching circuit in the form of an AND circuit for loop ring 40 and switches wires 25 and 26 (pick-up wire / pick-up wire). After the completion of the swap step, the dynamic memory element 45 is reset to its original position if the move command is no longer issued. In the operation mode Single control using the delay element 44, the pickup drive 26 is briefly switched off, as a result of which it can stop tripping just during the switching process of relay 67. During the operation mode Measurement, no switching pulses are generated. Only the dynamic memory element 45 is active, thereby providing for the interlocking of the servo 3 control elements. The reversible counter 41 is zeroed by signals 30 by means of an OR circuit 24. The servo control element 814 3 draws over the already described row selection information over the wire 33. In addition, it implements a single control and measurement of the memory function in the group operation mode. At the same time, it carries over the wire 29 to the control unit 1 information about the state of the storage device (the relay has tripped or not). In the Single-wire operation mode by wire 30, direction information is provided to the control unit. In the operating mode General control, the switch 64 serves to turn on the adjusting screw of the inking system in the system, and the switch 65 to turn off from the system. The wire 28 serves as an external control for the ink adjustment screw relay 67 in the operating mode. General control from the common control element 4. This element expands the general and group control information on the direction to the control unit 1. In addition, in these operating modes, it issues a swap command wire 32. During operation, general control, it controls, in addition, via wire 28 all the paint adjustment screws 67 and, thus, all cTpoKaNM matrices. The use of this device makes it possible to increase the accuracy of ink supply control on printing presses. It is recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic.
