Description

one

The invention relates to the field of winding automation.

A photoelectric device is known for detecting a filament breakage containing 1, its electronic indicator, a drive motor control unit, a photosensor, and luminaires.

Such a device does not give a specific indication of the location of the malfunction, which makes it difficult to operate such winding devices, reducing their productivity.

The purpose of the invention is to provide an alarm for the breakage or over-tension of one of the threads being wound onto a bobbin.

This is achieved by the fact that the proposed device is equipped with a clock pulse pulse generator, "1-1-NOT-OR" logic circuits, a delay line, and an electronic indicator is made in the form of two parallel registers (akaplpvayuyapdpkh registers with bits of bits by the number of controlled reels, and i Yes, the first register is connected by the corresponding photosensors, and the outputs are connected to the inputs of the second register, the outputs of each bit of which are connected to the corresponding light flux lamp and through the OR circuit with the input of the drive node) I eat schnny for reading obonh regnstrov combined and connected to a generator of clock pulses, and via the delay line - to the chains resetting the first register.

The drawing shows a block diagram of the proposed device.

The device consists of winding reels / -3 with ierforpirovannymi Dpskamp; lamps 4-6 light flux; photoelectric sensors 7-9; the first accumulating register containing the triggers 10-12 and the elements "AND NOT 13-15; the second accumulating regspstra containing triggers 16-18 and the elements of AND-NOT 19-21; 22 clock pulse generator; the element “OR 23; delay lines 24 of engine control unit 25; engine 26; coils 27 on which a thread or wire is being wound.

A photoelectric device for determining the breakage of a thread material works as follows.

In the initial state, triggers 10–12 receive elements 13–15 with positive potential, and triggers with elements 19–21 receive a positive potential.

Clock 22 does not work.

When the device is started up, the motor 26 begins to rotate, rotating the spinner 27, which, through the H1HT11 il wire, transmits the rotation to reels / -3 n perforated discs. Perforated discs modulate the luminous notes coming from lamgg 4-6 luminous flux to photoelectric sensors 7-9, from which the pulses arrive at the W-12 triggers and transfer them. Elements 13-15 will receive positive potentials. After a period of time required for the engine to develop an icoleon, the 22 clock pulse generator starts to work. From it, negative polling pulses are read on the read buses, the repetition rate of which is less than the lowest possible pulse frequency from photoelectric sensors. The prp nefedi breakage of the threads or wires of the reel / -3 rotate and the flip-flops} 0- / 2, as indicated above, are thrown. With the passage of a pulse from the generator 22 clock pulses to the elements 13-15 at the output of the latter, as well as the output of the elements 19-21 pulse will not. One way the pulse from the generator of clock pulses enters the delay line 24. Lastly, after a certain period of time, it sends a signal to the cepp reset of the first reg signal. The triggers are returned to their initial position. The process is repeated. If, for any reason, the thread tension increases, naimer on the reel /, then the rotation speed of the reels will decrease, and by the time the polling pulse arrives from the generator 22 clock pulse pulses, trigger 10 does not have time to transfer. At the output of the element 13 in Wits imuls, which revolves the trigger 16 of the second register, PA output of the same element

19, periol1, impulses will begin to appear. The first of these, through the scheme OR 23, acts on the motor control unit 25, which stops the engine 26, thereby stopping the rotation of the coil 27. At the same time, these pulses affect the lamp-beam of the light flux, which starts to flash, signaling the place of operation disruption.
