Claims

The device contains a unit of 1 logic elements, a follower element 2 controlling the rotation of the drum and a relay 3 times. The logic element unit 1 includes a trigger 4, a time pulse generator 5, elements AND 6-8 and a reversible counter 9. The follower element 2 for controlling the rotation of the drum includes a permanent magnet 10, connected to the drum shaft 11, and a reed switch 12 The device operates as follows. When the device is turned on, the pulses from the generator 5 time pulses (for example, after 1 s) arrive at the counting input of the trigger 4. If at the initial moment the trigger 4 is in a position where the high potential from one of its arms goes to the input of the element And 6, and the low potential — to element 7; when pulses arrive from the output of the tracking element 2 to the second input of element 6 from its output, the pulses go to the reading input of the reversing counter 9. After 1 second from generator 5, another pulse arrives, which overturns the trigger p 4 to another state, the output of which resets the reversible counter 9, triggers the time relay 3, which is set to delay the 2T pulse from the generator; torus 5, and the input of element 7 is prepared, the second input of which receives pulses from the tracking element 2. From the output of element 7, pulses are written to the reversing counter 9. After 1 second from generator 5, the pulse is again removed, which flips trigger 4, and prepares - with input element I 6. Through element I 6 from the next element 2, pulses are passed to the subtractive input of the reversing counter 9. If the rotation speed of the reel has not changed, then the number of pulses recorded in the reversing counter 9 through element 7, will be equal to lichestvu pulses received via the AND gate 6 for subtraction down counter 9. In this case, a reverse output. the counter 9 removes the signal arriving at the second input of the element 8, the first input of which is prepared by a high potential from the trigger 4. From the output of the element 8 it is removed a signal that returns the time relay 3 to its initial state. As the speed of the reel increases, the number of pulses received by the subtraction. In the reversible counter 9, will be greater than during the recording, and the operation of the circuit will be similar, i.e. in the end, the relay will be reset to its initial state every 3 times. If the grief of the reels decreases, then the number of pulses received through element 6 of the subtraction into the reversible counter 9 will be less than during the recording. The signal from the output of the reversible counter in this case is not removed, and consequently, is not removed from the output of the element 8. The time relay will also go off after 2T, the output of which will switch off the actuator. The device is simpler known due to the introduction of a time relay, which makes it possible to perform a block of logic elements according to the scheme. not requiring complicated setup, and as a result, the reliability of operation of the device is increased and ease of maintenance during its operation is ensured. In addition, reliability is enhanced by the use of a proximity sensor. There are no high voltages in the device, which increases the safety of the device. The absence of sparks in the device allows it to be used in explosive rooms. Claim 1.
