The purpose of the invention is to increase the reliability of the device.

This goal is achieved by the fact that the device contains a group of elements AND by the number of actuators, two elements OR element AND-IE and a trigger, the first inputs of the group of elements AND are connected to the corresponding outputs of the matching blocks, the second inputs - to the second output of the pulse distributor and to the first the trigger input, outputs to the corresponding inputs of the first element OR whose output is connected to the first input of the NAND element, the second input of which is connected to the inverse output of the trigger, and the output to the third control key input The second input of the trigger is connected to the output of the second OR element, the first input of which is connected to the third output of the mode switching signal generator, and the second input to the third output of the pulse distributor. The drawing shows the proposed System, functional scheme. The device contains a power supply unit 1, a frequency generator 2, a key 3, a matching unit 4, a pulse distributor 5, a reset unit 6, a first element OR a control panel 8, a mode selector driver 9, an actuator 10, a dial unit 11 programs, key 12 Start, switch 13, a group of elements AND 14, element AND-NOT 15, the second element OR 1b, trigger 17. The device works as follows. When the power source 1 is turned on, the installation unit 6 automatically sets the device to its initial state. At the same time, generator 2 starts to work, but its output is closed with a signal from key 3. In block 11, a given program is dialed, for which jumpers connect the outputs of unit 5 to the inputs of the blocks. When key 12 is pressed, key 3 receives the enable signal to generator 2, pulses from generator 2 are fed to the input of distributor 5, from which they are sequentially distributed over time to the sockets of the switching field of unit 11. From unit 11, the switching-on pulses go to inputs of blocks k, switching on and off actuating mechanisms 10 .. State signals from blocks k are continuously fed to the inputs of the And 1 elements, other inputs of which are clocked by clock pulses Polling from the distributor 5. Output signals from the And elements of group I are received on the element OR 7, which feeds on the element AND-NOT 15 prohibiting signal in the presence of a signal from at least one of the blocks. The presence of a signal from blocks k after the end of the operation cycle indicates that a failure has occurred in them and not all actuators are in the initial state, which is a prohibiting condition for the start of the next cycle. The passage of the prohibitory signal to you-. the stroke of the NAND 15 element is blocked by the trigger 17. The last pulse of the cycle The end of the cycle from the output of the distributor 5 goes to the elements 16, and the trigger is transferred to the Control state. The output signal of the trigger 17 is fed to the input element AND-NOT 15, allowing the passage of the signal from the output of the element OR 7 to the output of the element I-ME 15 and then to the key 3. Thus, if there are actuators on, the key 3 receives a inhibitory signal closes the output of generator 2. When switching from manual mode to automatic driver 9, it forms a signal Rumn.Ant., which enters another input of the element OR 16. Then the process repeats. If all the actuators are in the initial state, then the inhibit signal from the element 15 о.is not present, and the trigger 17 by the first clock pulse of the generator 2 returns To the State of Operation The invention formula The device for programmed control of technological operations containing the key with the first output of the setup unit to the initial state, with the control input of the pulse distributor and with the installation inputs of the matching blocks, the output with the first input of the frequency generator, the first control input - with the key start, the second control input - with the first output of the mode switching signal generator, the second output of which is connected to the first inputs of the matching blocks through the control panel, the second inputs of which are connected to the output of the program set block, the input of which is connected to the first output of the pulse distributor, frequency which input is connected to the output of the frequency generator, the second input of which is connected to the second output of the installation unit to the initial state; the outputs according to the matching blocks are connected respectively to the input ladies actuators, the input of the mode switching signal generator is connected to the output of the mode switch, characterized in that, in order to increase the reliability of the device, it contains a group of elements AND by the number of actuators, two elements OR, AND-NOT element and a trigger, the first inputs the groups of elements AND are connected to the corresponding outputs of the matching blocks, the second inputs to the second output of the distributor are 6 pulses and to the first input of the trigger, the outputs to the corresponding inputs of the first element OR, the output is It is connected to the first input of the NAND element, the second input of which is connected to the inverse output of the trigger, and the output to the third control input of the key, the second input of the trigger is connected to the output of the second element OR the first input of which is connected to the third output of the mode switching signal generator, and the second input with the third output of the pulse distributor.
