Abstract

The invention relates to devices for monitoring and measuring the average speed of rotation of the moving objects. The purpose of the invention is to control the rotational speeds of moving objects. The rotating spindles 12 pass by the inductive sensor 1 and the photoelectric sensor 5. The pulses on the passage of spindles 12 are transmitted from the inductive sensor 1 to the threshold element 2 and are read in the control unit 3 for measuring the spindle drum 13.

Description

I

The invention relates to instrument making, namely to devices of a king and measuring the average value of the rotational speed of moving objects (cotton spindle machines),

The aim of the invention is to provide control of rotational speeds of moving objects.

The drawing shows the block diagram of the device.

The device contains a sensor 1 passing the spindles, the first threshold element 2, the unit 3 controls the measurement period, the element And 4, the sensor 5, such as a photoelectric, the second threshold element b, the recalculation circuit 7, the counter 8 pulse

owls, decoder 9, indicator 10, block 11 reset information, the beginning of the test, the spindles 12, spindle drums 13, black and white sectors 14.

Sensor 1, for example, inductive through threshold element 2 is connected to the input of unit 3 for controlling the measurement period of spindle drum 13, the output of which is connected to the first input of element AND 4, the second input of the latter is connected via second threshold element 6 to the output of photoelectric sensor 5 the spindle rotation speed, and the output of the AND 4 circuit is connected via a recalculate; The circuit 7 with the input of the counter 8 and fflylsov, the output of the latter is connected through the decoder 9. with the input of the digital in 10, the 10.

The device works as follows.

The spindles 12, rotating around their axis and moving along with the spindle drum, pass by the stationary inductive sensor 1 and the photoelectric sensor 5. Pulses about p oh the spindles 12 are transmitted from the inductive sensor 1 to the threshold element 2 and are read in the 3.control unit and the spindle drum 13, for a specified time, i.e. to us

the speed and rotation of the spindles is enough 10 turns of the spindle drum), at the output of the unit 3 controls the measurement period of the spindle drum 13 there is a logical unit, the logical element I 4 is open. Black and white sectors 14, located on the surface of the heads of the spindles 12, at the output of the photoelectric sensor 5 cause the appearance of pulses proportional to the speed of growth of the spindles 12, which are formed by the threshold element 6 and are supplied to the second input element and 4. Since the first input element And 4 matches are open, then the pulse, proportional to the speeds of Brush, ekey pieces 12, from the output of the And 4 element is input to the recalculation of the 1st circuit M1.I 7,

The purpose of the scaling circuit 7 is to obtain information about the average speed of rotation of the spindles 12. The pulses from the output of the scaling circuit 7 are fed to the input of the counter 8 pulses. On the digital display unit, the average value of the speed of the rotary drum of the Units of one drum will be displayed.
