The invention relates to a pulse technique, specifically to decimal counters, and can be used in winding machines for setting and counting the number of turns with the selection of a specified pulse used in the drive of the machine to start braking, and also can be used in process plants various applications, such as control, metering and dosage systems for the reagent.

The aim of the invention is to simplify the device and increase its reliability.

The drawing shows a block diagram of the device.

The device contains the first group of counters 11-14, the first group of setters 2i is 2z, the first element is AND 3, the second group of counters 4i is 44, the second group of setters 5i is 5z, the second element is AND 6, input 7 of key 8, input 9 of which is connected with the Start button of the sensor, 10 pulse generator, element OR 11, counting input 12 of the first counter 4i of the second group of meters 4i - 44, counting input 13 of the first counter 1i of the first group of counters 1i - 14, third element I 14, the first group of elements NOT 15i - 154, the second group of elements HE 16i - 16, the memory element 17 and the delay element 18, the Start button 19 and the outputs 20 and 21 of the element 13 delay.

Switches of setters of the first group of setters 2i - 24 set the programmed (nominal) number of turns, for example 1000. Then an intermediate number, for example 900, is selected, with the appearance of which braking should start (reduction of the winding speed). Switches of setters of the second group of setters 5i, -3h set the difference between the given (1000) and intermediate (900) values (the remainder of the turns), i.e. the number 100. Turning on the Start button 19 opens input 8 of key 8. At this, the pulses of the generator 10 through the key 8 and the OR element 11 fill the counters of the second group of counters 4i - 44 until they coincide with the set value of the remainder of the coils (i.e. 100). At this moment, the inputs of the elements NOT of the second group of elements HE 16i - 163 are set to zero, and the inputs of the element AND 6 are ones. Therefore, a single signal from the output of the element And 6 closes on the input 7 of the key 8 and includes winding machine.

With the machine turned on, the Device Input receives single signals from the turns sensor (not shown), which at the inputs 13 and 12 fill the counters of the first

11-14 and the second 4i-44 groups of counters. Since the number 100 is recorded in the counters of group 4i-44 before the start of the counting, the counters are filled in first before the specified number 1000

groups of counters 4i - 44 (when in counters of group 1i - 14 number 900). At the same time, the zeros installed on the tires of the counters of the 4i-44 counter group corresponding to the 1000y number, suppress the units on the same-named counter buses of the counters of the 1i counter group, 14, and the inputs of the NOT elements of the 15i-154 groups are set to zeros; 3 - units. At the first output of the device (intermediate pulse), a slowdown speed signal appears. At the same time, this signal includes memory element 17. After a time determined by the parameters of the delay element 18 (sufficient for the counters of the group of meters 4i - 44 to change their state), a signal is sent to the input 21 of the element 14 and that prepares the element 14 to operate. Then, along the counting path (after 100 pulses), the counters of the first group of counters 1i - 14 are filled to a predetermined number of 1000 pulses, the signal through the elements of the first group of elements is NOT 15i - 154, the element 3 is fed to the input 20 of the element 14 and appears

0 at the third output of the device (given impulse). This signal turns off the machine drive. Moreover, its presence at the first output (intermediate pulse) does not affect the machine drive, since
