Abstract

The invention relates to methods of non-destructive testing and can be used in the inspection of long products in automated lines. The invention is in addition to the author. swith No. 1004862. The purpose of the invention is to increase the reliability of control due to the detuning from the signal of repaired defects in the presence of defects. Signals from the flaw detector. The defect to be repaired and the Marriage arrive at the input of the device. The Marriage signal triggers a standby multivibrator 1, which forms a single pulse from a sequence of signals, the front-to-edge 2 circuit separates these signals, the single vibrator 3 calibrates them in duration, the switch 5 of the defect-testers switches the defect-meters which carry out the product marking. In the presence of a signal, the Reject is also blocking the channel of the Repairable defect due to the fact that the signal from the output of the waiting multivibrator 1 closes the OR-NOT 12 element to the signals from the repaired defects that do not pass to the defect meters. 1 il. § (L t3 th

The invention relates to the field of flaws in long products and can be used in conjunction with automated control installations that scan products by category of repaired defects and final marriage, and is an improvement on the device by the author. CBv, f 1004862.

The purpose of the invention is to increase the reliability of control at the expense of the detuning from the signal, we repair gx defects in the presence of defects.

The drawing shows a structural diagram of the device.

The device of the coordinate defectus contains a series-connected standby multivibrator 1 with a restart, circuit 2 at the front and rear edges of the Pulse, one-vibrator 3, a two-input element SHSh 4, switch 5 for defectometers, block 6 of information transfer about defects, the unit 7 of the control of the defectometers and the unit 8 of the defectometers. The device also contains sensors 9 and 10 clock pulses connected to the defect information transfer unit 6 and the inverter I1 connected in series and the WLNHONE 12 element, the second input of which is connected to the output of the waiting multivibrator 1, and the output to the second input of the two-stage element OR 4. The drawing also shows the flaw detector 13, the outputs of which are connected to the inputs of the waiting multivibrator 1 of the inverter 11.

The coordinate flaw device works as follows.

A series of pulses on the presence of a final marriage from the output of the flaw detector 13 Marriage enters the input of the waiting multivibrator 1 with a re-launch, which converts them into one rectangular pulse. The signal from its output enters the input of the SHSh-HE 12 element and blocks the passage of the signal from the repaired defective unit. P. Geresi

the element OR 4. In addition, the signal from the output of the standby multivibrator 1 is fed to the circuit 2 of the front and rear edges of the pulse

This results in the formation of two short impulses corresponding to the leading and trailing edges of the impulse and, consequently, to the beginning and end of the defect, the final defect.

The impulses of the beginning and end of the defect are fed to the input of the one-shot 3, which: generates pulses of them with a constant duration T. The duration of the generated pulse you T

they take within --- T T, where

T is the period of rotation of the controlled product, N is the number of defect-meters.

The pulses from the one-shot 3 are fed to one of the inputs of the element OR 4, the second input of which receives signals from the flaw detector channel 13 / Repairable defect, however, signals about the presence of a final defect or repaired defect can only be received alternately, i.e. when there is a final defect in the channel of the defect being repaired

ban. Next, the pulses from the circuit are fed to the input of the switch 5 defect-meters, i.e. operate on a single channel, controlled by a block of 8 defect-meters.
