    • 专利摘要:
    A printing machine operates at a variable speed, and includes a rotary reference component. Activation and deactivation of positioning units for printing cylinders and other functional units for the printing machine is performed in synchronization with the rotation of the rotary reference component. The positioning units exhibit dead times in their response to applied activating or deactivating signals. The duration of each such dead time expressed in terms of the extent of angular movement of the rotary reference component varies in dependence upon printing machine operating speed, tending to produce improper synchronization between activation and deactivation of positioning units, on the one hand, and machine operation, on the other hand. The speed of operation of the printing machine is monitored and employed to automatically introduce a compensatory time delay into the application of activating or deactivating signals to the positioning units, to compensate for the dead times and maintain proper synchronization.

    This invention relates to press control devices.
    The aim of the invention is to increase the efficiency of the poisoning.
    FIG. 1 shows a structural control system circuit; in fig. 2 - the ciicrcMiM unp> unprofile scheme;
    The device contains a sensor 1, an arithmetic unit 2, a clock unit 3, a converter 4, pre-assignment for converting the computed values into machine codes, an executive unit 5, a node 6 for compensating the delay time, 1 organ, multivibrator 7 with one meter of state, element E 8, central processing unit E, element OR 10, counter 11, multivibrator 12 with two stable states, elements E 13 and 14.
    The device is driven by clock signals C | and € 2 (Fig. 1), which come from the clock generator outputs (not shown).
    The actuator control system compensates for the delay time of the control signal for the executive organ depending on the angular velocity of the press.
    The control angle at which the signal is delayed at higher angular velocities is less than at low angular velocities. For the control of its angle, depending on the angular velocity jj of the printing machine, the equation
    P aa) + b,
    where a is a constant value depending on the constructional parameters;
    b is a calculated value.
    The dead time compensation unit of the actuator consists of a control signal driven by a clock signal C i of the arithmetic unit 2 and a control signal controlled by a clock signal CA 4 for converting the calculated values into machine codes. The clock signals Ci and C2 are retracted from the printing machine. The sensor 1 for issuing the angle of rotation of the printing press is part of the node 6 for compensating the delay of the actuator.
    At the end of the calculations, the resulting races. an even value is driven by the press control signal C-2 by the converter 4 to a parameter related to the press. This parameter is used as a clock signal C 3 to control the clock unit 3, which, in accordance with the command Q, is controlled by the actuator 5.
    The node 6 for compensating the delay time of the executive body consists of an arn (| e of the legendary 2. transducer 4 and sensor 1 for determining the angle of the printing press.
    The central processing unit 9, to which the element OR 10 belongs, the counter 11, depending on the state of the element AND 8 or 13, is activated from the arithmetic unit 2 or from the converter 4.
    The control sequence of the node 6 for compensating the delay of the executive body is divided into three successive phases: the calculation of the control angle (3, the accumulation of the control angle p and the issuance of the control angle p.
    Calculation of the control angle p.
    This phase is triggered by a clock signal. IOM Ci and processing in the arithmetic unit 2. In this case, the monostable multivibrator 7 starts working and opens the element AND 8, the second input of which is connected to the sensor 1 for issuing the angle of rotation of the print mask.
    The pulses of the angle of rotation during the passage of the monostable multivibrator 7 are fed to the central processing unit 9.
    Accumulation of the control angle p.
    This phase is determined during the calculation of the control angle p, i.e. when a monostable multivibrator 7 passes through, the part of the counter 11 characterizes the term (my) of the above equation for the control angle. If the volume of the counter 11 does not correspond to the b bits, the unset part of the counter forms the summand (b-aoo) equation for the control angle p.
    Issuance of the control angle p.
    This phase is triggered by a clock pulse C2 and processed in converter 4. In this case, a bistable multivibrator 12 is started.
    The activated bistable multivibrator 12 switches the angular pulses coming from the sensor 1 to the central processing unit 9 through the element 13 and the pulses from the output of the element 13 and through the element OR 10 fall on the counter 11 partially installed in the first phase. runs until all its individual drives have been installed. This state is established by the element AND 14, to which all the outputs of the counter 11 approach. Thus, the term (L-aw). corresponding to its control angle p, from the calculated value that was in the counter 11, with the aid of the sensor 1 is converted into the corresponding parameter of the printing mask.
    Element I 14 also generates a signal that returns the bistable multivibrator 12 to the initial state and controls, via the clocking unit 3, the executive unit 5.

    The device can be used to shut off the actuator.
    Different time of switching on and off of the organs. 1H11go, 1ny organs can be achieved by installing the appropriate time of the monostable multivibrator 7 and the volume of the counter 11. With the help and compensation unit 6, the response time of the mono-stable can be ensured multivibrator 7 and counter 11. The response time of multivibrator 7 in this case must correspond to the deceleration time ti of the actuator. It defines the maximum required control angle | 3.
    Offered. My device will improve the efficiency of printing machine management.
