    The known system has a number of disadvantages.
    The purpose of the invention is to eliminate these disadvantages.
    The goal is achieved by the fact that the control system of printing machines with synchronous clocking and start-up, containing transmitting shift registers with clock and information inputs, the outputs of which are connected to actuators for actuating the functional groups of printing machines, has shift registers, clock device with a predetermined number of periodic clocks for every 360 ° and a clock device with one periodic beat for every 360 °, while the actuators are associated with shift controls new registers whose clock inputs
    connected to a clock device with a specified number of periodic clock cycles for every 360 ° and with transmitting shift registers, the clock inputs of which are connected to a clock device with one clock and a periodic clock for every 360 °.
    The system has a device for controlling sheet feeding connected to the press and an additional transmitting shift register, the information input of one of the control shift registers is connected to the device for controlling sheet feeding, the information inputs of the transmitting shift registers are connected to one of the outputs of the additional transmitting shift register, and the executive units of the functional groups are associated with control shift registers. In addition, the system has an additional control shift register, a clock device of the clock signal, while the clock inputs of the transmitting shift registers are connected to the corresponding outputs of the additional control shift register, the information input of which is connected to the clock device of its synchronizing signal, the information input of the first transmitting shift register connected to the device for controlling sheet feeding, information inputs of other transmitting shift registers of the junction Yeni with the outputs of the corresponding transmitting shift registers, and the executive units of the functional groups are connected to the corresponding inputs of the first transmitting shift register. The control system has an OR element, a circuit that controls the speed range, additional shift registers and a device to compensate for the delay, which is uJ, it is from AND elements, and the AND elements are connected to the outputs of the additional shift registers, and the outputs of the AND elements are connected to the control the speed range of the circuit and the OR element connected to the other outputs of the AND elements, the control shift registers being connected to the device for delay compensation. The system has a device for suppressing pulses consisting of a memory unit and a pulse shortening unit, while the installation input of the unit p.m. is connected to the output of the device for delay compensation, the installation output of which is connected to the input of the corresponding control shift register connected to a device for suppressing pulses, moreover, the control shift register is made in the form of a ring counter. The inputs of the delay compensation device are connected to the corresponding clock device of the clock signal. FIG. 1 shows transmitting shift registers, in a sequential scheme; in fig. 2 - the same, in a parallel-sequential scheme. The control system (Figs. 1 and 2) consists of control shift registers 1 and transmitting shift register 2 connected to each other. Shift registers 1 and 2 each have one clock input T and one information input 1. The control system also contains a device 3 to compensate for the delay. The clock inputs Tp of the control shift registers 1 are connected to the first clock device 4, producing for a certain 360 ° a certain number of periodic cycles, for example, every 30 °. The clock inputs of the transmitting shift registers 2 are connected to devices producing for each 360 ° one periodic clock and a device producing one periodic clock for every 360 ° executed as the second clock device 5 (first embodiment) or as control shift register 1 (second embodiment), in which at the output of one bit for every 360 ° there is one signal. The control system includes actuators 6, a device 7 for controlling sheet feeding, a manual control device 8. The device for delay compensation 3 consists of several elements AND 9 whose first inputs are connected to the successive bits of the control shift register 1. The number of bits is oriented, taking into account the sequence, to the required compensation section. If the required compensation area is, for example, O-90 °, then with a periodic clock of 30 ° four bits are needed to connect the device. The second inputs of the AND elements 9 are formed by the outputs of the control circuit 10. The latter is connected to the input that is connected to machine controlled speed sensor (not shown). The control circuit 10 has several outputs connected to elements 9. At the same time, each output has a certain range of speed, for example, the first output is the speed range 0-3000, the second output is 3000--5000, the third output is 5000-7000 and etc. The analog-to-digital conversion of the analog values of the speed numbers is carried out using well-known means and therefore is not explained in more detail. Behind the outputs of the AND 9 elements is an OR 11 element, which forms the output of the device for delay compensation 3. Behind the delay compensation device, the execution units 6 are directly located (control system also contains a device 12 for suppressing pulses), element 13 , a memory unit 14, an AND element 15, a control device 16, a clock device 17, a memory block 18 and a shortening block 19 and pulses. The first embodiment is shown in FIG. 1. The control shift registers I and the transfer shift registers 2 are connected in series. The execution units of the functional units 6 are executed directly by the control shift register 1, loaded with a subdivision of measures (for example, 30 ° cycles) through a device to compensate for the delay 3. Shunting from one control shift register to another is performed in areas where starting is not required of the executive links 6, by subdividing clock cycles, for example, 360 °, using transmitting shift registers 2. Instead of clock cycles of 360 °, any other coarse sub-360 ° is also possible venno ispolrazdelenie
    ny of the car. The information input Ig of the first control shift register is connected to a device for controlling the feeding of sheets 7, which controls the input of each sheet to the printing press. The information inputs of 1% of the subsequent shift registers are each connected in accordance with the distribution of rotation angles of the printing sections with one output, in most cases with the output of the last bit of the existing shift register.
    A second embodiment is shown in FIG. 2. Here there is only one control shift register 1. For control shift register 1, devices for delay compensation 3 are connected in the described manner. Information input Is of control shift register 1 is connected to a third clock device 17, generating a periodic clock signal. In this case, synchronization can be carried out only at the beginning of control or at the beginning of control and during operation of the mask. The outputs of the delay compensation device 3 are connected via devices for suppressing pulses 12 with clock inputs of the transmitting shift register 2.
    The device for suppressing pulses 12 consists of a memory block 18, the setting input of which is connected to the output of the corresponding device for delay compensation 3, and the reset input is connected to the bit of the control shift register 1 located behind the latter connected to the corresponding device for delay compensation 3 bits, and a pulse shortening block 19, for example, a monostable multivibrator.
    The information input Ig of the first transmitting shift register 2 is connected to the device for controlling the feeding of sheets 7, the information inputs Ig of the subsequent shift registers 2 are connected according to the distribution of rotation angles of the printed sections with one output, in most cases with the output of the last bit
    upstream transmit shift register. Executive links 6 are located behind the first bit of the corresponding transmitting shift register 2.
    If necessary, a manual control device 8 is located between the first bit of the transmitting shift register 2 and the executive link 6, which ensures the inclusion of an automatic start cycle in the system and the corresponding executive link 6 that turns off from it. The manual control device 8 has an And 13 element, the second the input of which is formed by the output of the memory unit 14, whose inputs are formed through the element 15 and the output of the device for suppressing pulses 12 and the output of the control device 16. The first input is e The element And 13 is connected to the output of the first bit of the transmitting shift register 2.
    In one embodiment of the invention, the control shift register 1 is configured as a well-known ring counter. In this design, the third clock device 17 becomes unnecessary. With a special form of version 2, there is no control shift register 1. Each input of the device for delay compensation 3 is connected to a third clock device 17, which is separate for each input. The clock signals of clock devices 17 have an offset, which must be provided according to the requirements for example, an offset of 30 °.
    The principle of operation of the proposed device in the first embodiment is as follows.
    If there is a standard sheet to be further processed in the press, the device 7 for controlling sheet feeding produces a signal that the sheet is fed into the machine, and this signal is fed through information input IB to the control shift register 1. If there is a clock signal on the clock the input of Tp, a signal on the arrival of the sheet into the mashina enters the control shift register 1. Thus, each output bit of the control shift register 1 corresponds to a unique angle value.
    In this example, signals are transmitted to the first elements And 9 of the delay compensation device 3 when the angles are 30, 60, 90, and 120 °. Depending on the working speed of the mask, the AND 9 element receives a signal, so that the AND condition is fulfilled and the signal is sent through the OR II cell to the executive link 6.
    The latter is produced at the same time in action synchronously with the tact and in the correct sequence relative to other executive links. Depending on the number of revolutions corresponding to the current working speed of the machine, actuation of the executive link 6 is carried out at different times in order to compensate for the delay of the executive link, which is constant at each speed, by putting an earlier (at high speed) late (at low speed) launch of this link. The control shift register 1 can control several execution units of 6 functional groups. When the signal about the arrival of the sheet into the mashina enters the last bit of the control shift register 1, it is taken over by the transmitting shift register 2 and moved further in accordance with the revolutions of the second clock unit 5. Tying the transmitting shift registers 2 relative to the sections of sheet passage inside the printing area under which there is no need for synchronous control of executive links, means reducing the system on the basis of shift registers with precise synchronization with the start of the function -regional groups, which should be driven by de, ystvie synchronous with tact. If necessary, further control and transfer shift registers may be located behind control shift register 1 and transfer shift register 2. The principle of operation of the proposed device in the second embodiment is as follows. The control shift register 1 is started in the described manner via the clock input Tr and the information input 15. The third clock device 17 connected to the information input Ig every 360 ° produces a periodic clock signal for starting the control shift register 1. The third clock device 17 can output a clock signal also only to the beginning of control. Further processing of the signal in the delay compensation device 3 is performed similarly to the processing in the first version of version 1. The signal from the delay compensation device 3 instead of 360 ° clock cycles gives any other rough 360 ° subdivision according to the machine and serves after passing through the pulse suppression device 12 for triggering the transmitting shift register 2 in combination with a signal that a sheet enters the machine from a device to control sheet feeding 7. In a device for suppressing pulses 12 n the dead pulse is extended to a width of 90 ° in order to prevent a two-time clocking with an interval of 30 ° when switching from one speed range to another. For this purpose, the memory unit 18, triggered by a signal from the delay compensation device 3, becomes inactive and the signal applied to the output of the delay compensation device after the last possible signal is again reset to zero. Following this, the pulse is shortened in a stable multivibrator. Now, at the output of the first bit of the transmitting shift register 2, there is a signal for triggering the actuators 6 through the manual control device 8. The latter ensures that the actuator links 6 are synchronized with the clock into the automatic start-up cycle system and are switched off from it. When the control unit 16 does not touch, the unit 14 moves with the help of a signal from the device to compensate for the delay 3 in such a way that one signal is given. This signal is brought to the element And 13, in which the condition AND now is fulfilled and the start of the executive link 6 is synchronized with the clock. i.e., no signal appears at the output, as a result of which the AND condition in AND 13 does not fulfill and the executive link 6 is thus not activated. The sheet arrives at the machine after the clock shift in the transmitting shift register 2 to another transmitting shift register, and there it is combined with the signal from the slave to compensate for lag 3. The output signal of the transmitting shift register 2 serves to start the next group links 6. With a special form of execution the clocking of the device to compensate for the delay 3 is carried out by the third clock devices 17, located one at the outputs of the device for Lag compensation and feeds for every 360 ° one cycle. The clocks of the third clock devices are offset relative to each other, for example, at 30 °. 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.
