    The invention relates to the construction industry and building materials, in particular, to technology and equipment for forming glass products.  A known method of automatically controlling the operation of a machine for shaping glass products, including generating digital signals, is proportional to the angular displacement of the machine’s shaft and measuring the current time of the machine’s turn in each cycle, as well as a device for its implementation, including a pulse generator, kinematically connected to the shaft the machine and the angular displacement counter connected to the pulse generator Cl J.  The known method and the known device do not give a qualitative control over the operation of the machine, since they do not provide for a change in the time of operation of each section of the machine.  The purpose of the invention is to improve the quality of control by making it possible to change the operating time of each section of the machine.  The goal is achieved by the fact that according to the method of automatic control of the operation of the machine for forming glass products, including generating digital signals proportional to the angular displacement of the machine shaft and measuring the current turnaround time of each cycle, set the start time and end time of each section of the machine, compare them with the measured current turning time of the machine and start or stop the corresponding section of the machine when the corresponding predetermined time coincides ala and ending time of the machine with the measured current time po1zorota machine, wherein each machine section assigned binary address and is carried out starting or stopping of the machine section, the relative operation, which coincides with the current time measured by the machine rotation.  A device for automatically controlling the operation of the machine for frm {and glass products with controllable sectional valves, including a pulse generator, 1 synematically connected with the shaft of the machine, and an angular displacement counter, connected to the pulse generator, are provided with synchronous memory devices.  3 by the comparison unit, by the binary address counter, the manual buttons of the controls for the reversible counter, the binary-decimal decoder, and the source of art. robooscopic signal, gfichy the outputs of the angular displacement counter and synchronous memory device are connected to the inputs of the comparison unit, the source of the stroboscopic signal is connected to the inputs of the binary address counter and synchronous memory devices; the inputs of the binary decoder are connected to the outputs of the binary address counter and the comparison unit, manual control buttons through a reversible counter connected to the inputs of synchronous storage devices / and the output binary binary decoder connected to control inlet section valves.  FIG. 1 is a block diagram of the device; in fig. 2 and 3 are detailed block diagrams of a main working (operational) storage device associated with each unit for controlling each section.  The pulse generator 1 forms a series of cyclic clock pulses the upper limit of the frequency of which is determined by the cycle time of the blocks of the storage device of the system.  A reset pulse is also generated in the generator at the end of each machine cycle, whereby the frequency of the reset pulse is determined by the type of machine that is being controlled.  The pulse generator can work in such.  a time cycle in which the machine mode is divided into standard clock interval intervals, or the generator can operate on the basis of the machine cycle, in which case 360 clock pulses are generated within each cycle. For example, in the proposed invention.  using the device, it controls the operation of the glass-forming machine; the pulse generator includes; the corresponding standard devices for generating a pulse, mounted on the drive shaft of the glass blowing machine, form two series of pulses.  054 With the help of the first series of pulses, a cyclic clock pulse is generated for each degree of rotation of the machine, and with the help of the second, one pulse is generated for each turn of the machine.  Thus, the machine that is controlled is operated in a predetermined cycle, then one pulse is formed at the beginning of the machine cycle, and the second pulse is formed for every 1/360 of the share of the machine cycle.  The output signal from the pulse generator is applied to each of a large number of blocks of the storage device 2, each of which serves the machines.  Each storage unit contains address transfer schemes that determine which particular sections of the machine being controlled must be transferred to a control action at a given time.  Each storage unit servicing the machine includes a reversible counter designed to change the relative time of the machine cycle, to which a control action should be transmitted to the individual components of the machine.  The operator control device 3 includes buttons, with which the start and stop control is performed, for setting up the sequence for supplying control commands for starting or stopping the machine, which is controlled.  The operator control device includes a display, to which degrees are displayed, intended to instantly reproduce the timing of a cycle that expires for a given machine that is being controlled.  In addition, the operator’s control unit has buttons, Fast and Slow, for controlling a reversible counter installed in the storage unit 2 of the machine’s serving section, and a control system for individual functional elements for determining which operating element changes time mode under the influence of the signal from the reversible counter.  Preferably, the operator’s control device is located close to the machines so that the operation of the machine can be monitored while the various control functions in the operator’s control unit change.  The output of each block is memorized.  A unit 2 servicing the components of the machine is connected to an integrated joianaHOB unit coupled to the machine 4, in which mechanical drive devices are provided for the machine which is controlled.  A tape recorder 5 is also provided, which records the working commands generated by the decimal switching panel.  Thus, if the machines being controlled must operate in different modes, then the program corresponding to each particular mode can be recorded on the tape prior to its use.  From the output of the tape, the signal goes to the central control panel 6, by means of which the work of the machines is synchronized, which are controlled using sections of the memory block.  The manual override switch 7 inverts the clock pulse, and if it is closed to pin 8, the clock clock is inverted or shifted in phase by 180 °. pulses generated in the pulse generator. Using switch 9. the reset signal is inverted, and if it is closed to pin 10, the pulse arriving at its input is inverted. reset.  The reason for inverting either the pulses of pulses or the pulses of a reset is to prevent such a position where the leading and trailing edges of the clock pulse and the reset pulse coincide with each other.  If the falling edge of the reset pulse and one of the clock pulses coincide, then the counter installed in circuit 11, which determines the start order, may give an incorrect count, as a result of which an error will be entered into the computer clock.  Therefore, it is necessary that the reset pulse and the clock pulse be shifted out of phase relative to each other, while the switches 7 or 9 are never closed. The output of the circuit 12, which determines the state by which the clock pulse is transmitted, is connected directly to the circuit 11 determining the starting order of the angular displacement counter 13 and the internal clock generator 14.  In the present invention, the frequency of the clock pulses supplied to each of these circuits is 360 pulses per machine cycle.  However, since the shift register has 64 cells, each of them must be strobed once during each clock pulse, the frequency of the signals at the output of the machine clock pulse must be increased 64 times.  Accordingly, the generator 14 of the internal clock pulses contains a generator, whose operation is synchronized with the help of clock pulses received at its input from the circuit 12.  The signal from the generator output is separated by a counter in such a way that the generator 14 generates an output pulse at terminal 15 whose frequency is 63 times higher than the frequency of the cyclic clock pulse, and a large co. the number of gating output signals at terminals 16, which have the same frequency, but are shifted relative to each other in phase The clock pulse — and the reset pulse taken from the output of circuit 12 — also enter the logic circuit, which determines the trigger order, and start-up circuit 11, by means of which the synchronization of the work of one machine with other machines interconnected with it is carried out. In the case when it is necessary to control a glass-forming machine, this machine includes several separate sections, This synchronization of the operation of the feeder and the feed mechanism for each individual section is carried out using the circuit 11 defining the starting order.  The clock pulses enter the counter, provided in circuit 11, defining the start order, and the counter is reset under the influence of the reset pulses applied to the input terminal 17.  The signal from the output of the counter enters the circuit of the comparison device, from which, after the comparison is made, the signal to the reset enters the circuit of the counter of angular displacement 13.  To the other input of the comparison device, the signal comes from the following sources; preloaded shift register 18, switch l to manual control 19 or from.  a switch defining the order of the launch equipped with a wheel with a notch 20.  The input signal from the preloaded shift register 18 is transmitted from the central control panel and corresponds to the exact point in time at which the machine cycle is to begin. With this signal, which is fed into the comparator, the output pulse is fed to the angular displacement counter 19, which its purpose is a reset pulse designed to reset the degrees counter.  If manual start order control is required, manual control 12 is closed, in which case the signal is transmitted to the comparison device in order to send the reset pulses to the angular displacement counter 13.  If it is necessary to ensure for the future work a certain start order, then set the wheel with notch 20 in such a way that after the scheme 11, which determines the start order, a predetermined number of clock pulses arrives using a switch equipped with a notched wheel , a signal would be transmitted to a comparison device, with which a reset pulse would be generated and fed to an angular displacement counter 13.  The output from the output of circuit 11, which determines the start order, also goes to the accumulating adder of the communication data, to which the timed information arrives regarding when the reset pulse, which should go to the angular displacement counter 13, should be generated and directed to the central console controls for recording, for example, on a magnetic tape.  In the angle counter 13, the pulse count is converted into a parallel transmitted command, with the help of which it is determined by how many degrees the heading has turned during the time elapsed from the beginning of the movement cycle.  So on. The output of the degree counter is formed by a series of 360 commands, after which it is reset by the signal of a reset.  The signal from the output of the degree counter enters the comparison unit 21 and the output display panel 22 through the drive buffer. 23.  For example, LEDs, electron beam tubes or other indicating devices can be used as a display showing the number of degrees of rotation. In the comparison unit 21, there is another input that receives a signal from the output of the trigger circuit of the memory 24, the output of which 64 signals are sequentially formed, corresponding to 64 points of time from which the control action should be transmitted.  individual machine components.  The output signal from the trigger of the storage device 24 is also supplied to the storage device 2. 5, consisting of ten shift registers.  For each pulse generated by the pulse generator, 64 clock pulses are generated in the generator 14 internal timing pulses, which are used to time the ten shift registers.  In this mode of operation, all accumulation information in registers is transferred from memory 25 to memory 24 and back and compared with the signal from the output of the angular displacement counter 13 using the comparison unit 21 for the entire duration of each pulse generated at the output of the angular counter displacement 13.  From the output of the shift registers, a command is fed in parallel to the input of the storage device 24, and each time an internal clock pulse is sent to the shift registers.  The command entered into the triggers of the storage device 24 is then read back to the parallel in the first cell of each of the shift registers and at the same time enters the comparison unit 21.  The flip-flops are reset using gate pulses from the internal clock generator.  Strobe pulses that provide flip-flop triggers have the same frequency as the commands that are read into a block of memory 25 made up of shift registers.  Suppose that the angular displacement counter 13 reaches the value 120, t. e.  the machine made one third of its cycle.  The internal clock pulse generator 14 generates 64 clock pulses, which are used to synchronize the operation of ten shift registers, which form memory 25, through all 64 cells before the output signal of the angular displacement 13 reads the value 121.  Since each number is synchronously derived from the registers and fed back into the shift registers via memory triggers, a number or command is fed to the input of the comparison block 21; Suppose that one of the numbers contained in the register of the storage device 25 is equal to 120, t. e.  at this point in time, a control action should be transmitted to a specific component of the machine, for example, a draft form. In this case, one of the numbers contained in the shift registers must be 120.  Since the signal at the output of the angular displacement counter 13 corresponds to the number 120 and one of the 64 numbers entered in the memory device is also 120, the comparison signal at the output of the comparing device appears at the very moment when the signal the corresponding number 120, which is contained in the storage device 25, on the output of the triggers of the storage device 24.  This signal is inverted by inverter 26 and fed to the inhibit input of decipher 27, which performs the operation of converting binary code to decimal. This signal, which can be called an affecting signal, controls the operation of decoder 27, which performs the operation of converting a signal from binary code to decimal, whereby the corresponding trigger 28 is triggered.  In order to ensure the transfer of a control action to a specific machine kontonent, an address transfer scheme is provided containing a binary address counter 29.  Binary address counter. 29 performs counting at a rate of 63 counts per input. clock speed, t. e.  The binary address counter performs the counting at the same rate as the pulse shaping speed at the output of the generator 14 of the internal clock pulses.  The binary address counter 29 is reset after counting 64 by means of a reset circuit which has a valve 30, a trigger type memory 31 and a buffer control electrode 32.  The binary address counter is synchronized with the operation of the system using the source of the stroboscopic signal 33.  Each of the 64 counting operations performed by the binary address counter corresponds to the address of the synchronous storage device 25 associated with the machine section to which the control action should be transmitted.  Suppose that among 64 cells one memory cell contains a command that corresponds to the point in time at which the controlling action on the component (the machine should be directed).  The comparison signal is generated at the moment when the signal corresponding to the command embedded in the memory cell of the storage device appears at the output of the storage device 24 and enters the decoder 27, in which the signal is transferred from the binary to the decimal.  At the same time, the binary address counter is in a state corresponding to a score of thirty, and the signal corresponding to this account, sent to the decoder, in which the signal is transferred from binary to decimal, is converted into a control pulse, whose address corresponds to 30.  At the output of the synchronous memory, a signal is generated, which is transmitted through a circuit to a corresponding actuator of a sectional valve, such as a solenoid, for example, which is connected to a release circuit (not shown).  The solenoid in turn acts on the section valve, which connects or disconnects the power from the section which, respectively, must be started or stopped.  To change the time point of the cluster, in which the control action is transmitted to one or more components of the machine, the following is carried out.  The signal from the output of the storage device 24, which is fed to the comparison unit 21 and the storage device 25, is fed to the control circuit 34 and through it to the input with organized interference from the reversible counter 35.  The signal from the input with organized noise drops the reversible counter to a level of counting that corresponds to the signal received at the input with organized noise.  However, the establishment of a predetermined state of the reversible counter cannot take place until it receives a signal corresponding to this predetermined state.  The switch, by means of which the selection of the corresponding function performed by the component of the machine, is carried out in Action on the control device of the operator in order to transfer the numbers corresponding to the address to the valve 36, by means of which the selection is made.  The number corresponding to the address will be one of those 64 addresses, numbered from 0 to 63, which are contained in ten shift registers of memory 25 and correspond to the address of a particular component of the machine. Valve 36, with which the selection is made, is a gate valve a four-pole type that performs AND / OR functions, and can be any one that corresponds to this character, type.  At the moment when the address of the specific section of the machine is entered into the valve 36, the choice of counts, the count of the decimal addresses expressed in the binary code of the addresses 37 performs counting synchronously with the counter, the binary addresses 29 and the shift registers of the memory 25, when the counter the binary-coded addresses 37 reaches the same counting level as in the gate 36, which determines the selection, the signals are compared in the comparator device 38.  The output signal of the comparing device 38 is fed respectively to the valve 39, the output of which in turn receives a signal to one of the inputs of the valve circuit connected to the angular displacement counter 13, at the output of the ventilating circuit 13 connected to the angular displacement counter 13, forming -.  A signal corresponding to a predetermined, predetermined state is transmitted to the reversible counter 355, and accordingly a signal is inputted corresponding to the number appearing at the input with the organization and interference, which is read by the reversible counter in order to ensure a certain state reversible counter, which provides the possibility of counting from the input line with organized interference.  This number is the same as the number that corresponds to the signal at the output of the trigger of the storage device 24 and corresponds to the relative point in time. the cycle in which a certain component of the machine must; be started or stopped.  The signal from the output of the reversible counter enters the buffer device, which is used to activate the display fixing the number of degrees passed by the functional element installed by the operator in the control device of the operator, and this display is used to determine the degree or time from which should be transferred to the effect of a particular component.  The output signal of the reversible counter is also transmitted through several blocks of logic devices to the memory trigger 24. h If the operator needs to change the value of the moment in time, he presses the manual control buttons 40 and 41, depending on whether he wants the time to work with. The machine section has been increased or slowed.  The resultant signal is fed through a valve 42 of the EXCLUSIVE type OR to one of the BLOCK TRAINS of the timing control circuit and at the same time to the control input of the gate circuit connected to the angular displacement counter 13.  The signal from the output of the valve 42: type EXCLUSIVE OR will be applied to the second valve 43 of the type EXCLUSIVE OR, and then to the binary counter 44, in which one pulse is generated per series of 512 pulses corresponding to degrees of rotation of the machine on its output, and on the other output one impulse to a series of 8192 impulses corresponding to degrees of rotation of the machine.  Accordingly, the frequencies of the output signals of the counter 44 are respectively 1/512 and 1/8192 of the frequency of the signal generated at the output of the angular displacement counter 13.  These output signals are supplied to a selection valve circuit 45, which is of the same type as the valve 36 which makes the selection.  If it is desired that the counting of the reversing counter is performed at a standard low synchronous speed, then the quick turn switch knob 46 is transferred to the slow turn terminals 47, thereby forming one pulse per signal corresponding to 8192 degrees transmitted from the binary counter 44 reversible counter 35.  If it is necessary to provide a fast counting counter counting, the quick counting switch is transferred to the quick turn terminals, 47 whereby a signal is generated, fed to a selector circuit 45, which blocks a single pulse arriving at a signal corresponding to 8192 degrees and forms a dec t pulses per signal corresponding to 512 degrees.  In this mode, the reversible counter will work with higher speed.  The signal from the output of the reversing counter is fed to the triggers of the storage device 24 through a gate circuit connected to the counter of the angular displacement 13, the gate 48, making the selection, and the ventilation 49.  Due to the fact that there are valves 49 which, under normal conditions, overlap the output signal of the reversible counter, the output signal of the reversible counter is not supplied to the forward triggers of the storage device 24 until the number from the corresponding storage cell made of the ten shift registers, will not go to the gates 49.  Accordingly, at the output of the comparison device 38, a comparison signal appears, with which the valves 49 are started.  This control unit can only be started when the comparison is made under conditions in which the manual control button is pressed.  The control inhibitory signal comes from the timing control circuit.  With this, the possibility of reading ahead of time of the new Islam, entering the S triggers of the storage device 24, is eliminated.  All this concerns the operation of the device intended to change the numbers entered in the storage device 24 consisting of ten shift registers.  However, in the case when the control system was pre-configured, the corresponding degrees were entered into different cells of the storage device 25 through the triggers of the storage device 24.  The first signal corresponds to the number of degrees that must be entered into the memory device 2-4. This number in the form is transmitted to the valve 48, which makes the selection.  At the same time, the control pulse arrives at the control output of the valve 48, which selects to form a signal at the input of the preloaded shift register and to overlap the input signal from the gate circuit associated with the c-4th grid of the angular displacement 13.  Accordingly, the signal from the output of the valve 48, which makes the selection, enters the valve 49.  However, the output signal of the valve 48, which is applied to the trigger of the memory device 24, will not be controlled by the valves 49 until a comparison is made between the signal from the output of the binary-coded decimal addresses counter 37, and signal from the output of the selector valve.  Accordingly, the signal to the second input of the selector valve 36 comes from the preloaded shift register, and this input signal contains information on which cell of the storage device 24 the signal corresponding to the degree number should be entered.  The signal supplied to the second input of the selector valve, designated as the control input, blocks the signal from the switch that selects
    a certain functional element, and thereby ensures the passage of the address number transmitted from the preloaded register shift. When a comparison is made between the output signal of the selector valve and the output signal coming from the binary-coded decimal addresses 37 counter, a comparison pulse is generated in the comparison device, which is transmitted through the valves 50 and 51 to the valves 49. At this time the signal corresponding to the information contained in the preloaded shift register is transmitted to the trigger of the memory 24 and from there enters the cell of the memory 25,
    This sequence of actions is maintained until a degree is provided for each of the components that are controlled. At this point in time, the system is considered ready for operation.
