Устройство работает следующим об- разом.The device operates as follows.

Электродвигатель 1 через червячный редуктор 2 приводит во вращение пазовый кулак 3 и поводок 4 мальтийского механизма. Ротор 5 с четырьмя пазами 6 совершает прерывистое движение с выстоем через 90° с помощью креста 7 мальтийского механизма. В' момент выстоя ротора 5 шток 8, проходящий сквозь ротор 5, совершает возвратно-поступательное движение по замкнутому кинематическому циклу с помощью' пазового кулака 3. Вместе со штоком 8 движутся диск 9 с закрепленными на нем толкателями 10-12 и шибером 13 и выталкивающие вилки 14 и 15. Проверяемый П-образный сердечник 33 за время одного такта возвратно-поступательного движения штока 8 шибером 13 переносится из кассеты 16 в паз 6 ротора 5, после чего совершает вместе с ротором 5 поворот на 90°. Во второй такт возвратно-поступательного движения штока 8 толкателем 1.0 сердечник перемещается в первый измерительный узел 17, где происходит измерение его электромагнитного параметра в контакте с П-образным замыкателем 19, и переносится вновь в паз б ротора 5 с помощью выталкивающей вилки 14» После очередного поворота сердечника 33 на 90° толкателем 11 сердечник перемещается во второй измерительный узел 18, где происходит измерение его электромагнитного параметра в контакте со вторым П-образным замыкателем 20 второй плоскостью, и переносится вновь в паз б ротора 5 выталкивающей вилкой 15. Следующий поворот ротора 5 на 90° переносит сердечник 33 на позицию сортировки, где он выталкивается толкателем Ϊ2 в канал уз ла 23 распределения проверенных сердечников .The electric motor 1 through the worm gear 2 rotates the groove fist 3 and the leash 4 of the Maltese mechanism. The rotor 5 with four grooves 6 makes an intermittent movement with a dwell of 90 ° using the cross 7 of the Maltese mechanism. At the 'moment of rotor 5 standstill, the rod 8, passing through the rotor 5, makes a reciprocating motion in a closed kinematic cycle with the help of a' groove fist 3. Together with the rod 8, the disk 9 moves with the pushers 10-12 and the gate 13 fixed on it and eject forks 14 and 15. The checked U-shaped core 33 during one stroke of the reciprocating movement of the rod 8 by the gate 13 is transferred from the cartridge 16 to the groove 6 of the rotor 5, after which it rotates 90 ° with the rotor 5. In the second cycle of the reciprocating motion of the rod 8 with the pusher 1.0, the core moves to the first measuring unit 17, where its electromagnetic parameter is measured in contact with the U-shaped contactor 19, and is transferred again to the groove in the rotor 5 using the ejecting fork 14 "After the next rotation of the core 33 by 90 ° with the pusher 11, the core moves to the second measuring unit 18, where its electromagnetic parameter is measured in contact with the second U-shaped contactor 20 by the second plane, and transferred to put the rotor 5 into the groove of the rotor 5 with the ejector fork 15. The next rotor rotation of the rotor 5 by 90 ° transfers the core 33 to the sorting position, where it is pushed by the pusher Ϊ2 into the channel of the distribution node 23 of the tested cores.

В момент кратковременного останова штока 8, когда в измерительные узлы 17 и 18 введены проверяемые сердечники 33 и генератор 24 формирует сигналы на токовые обмотки измерительных узлов 17 и 18, происходит поочередное подключение коммутатором 25 измерительных обмоток 21 и 22 к дискриминатору 26 пороговых значений. При этом в первый регистр 27 заносится результат измерения в первом измерительном узле 17, в третий регистр 29 результат измерения во втором измерительном узле 18, а во второй регистр 28 переписывается предыдущее Состояние первого регистра 27. Так как каждый проверяемый сердечник 33 проходит измерение последовательно в измерительных узлах 17 и 18, то на выходах второго и третьего регистров 28 и 29 присутствует информация об измеренном электромагнитном параметре одного конкретного сердечника 33, прошедшего измерение при контактировании . с П-образными' замыкателями 19 и 20 разными плоскостями. Эта информация поступает на логический блок 30, который формирует управляющие сигналы на исполнительный механизм 34 (например, поворотный электромагнит) узла 23 распределения проверенных сердечников в бункеры годных и бракованных » сердечников.At the moment of a short stop of the rod 8, when the test cores 33 are inserted into the measuring nodes 17 and 18 and the generator 24 generates signals to the current windings of the measuring nodes 17 and 18, the switch 25 alternately connects the measuring windings 21 and 22 to the threshold discriminator 26. In this case, the measurement result in the first measuring unit 17 is entered in the first register 27, the measurement result in the second measuring unit 18 in the third register 29, and the previous state of the first register 27 is written to the second register 28. Since each core being checked 33 is measured sequentially in the measuring nodes 17 and 18, then at the outputs of the second and third registers 28 and 29 there is information about the measured electromagnetic parameter of one particular core 33, which passed the measurement upon contact. with U-shaped 'contactors 19 and 20 different planes. This information is fed to a logic unit 30, which generates control signals to an actuator 34 (for example, a rotary electromagnet) of the tested core distribution unit 23 into the bins of suitable and defective cores.

Описанное устройство предполагает загрузку сердечников путем смены кассет, а зарядка кассет сердечниками должна заряжаться вручную или на специальном устройстве.The described device involves loading cores by changing cassettes, and charging cassettes with cores must be charged manually or on a special device.

С целью автоматизации процесса зарядки кассеты 16 устройство снабжено вибрационно-загрузочным устройством 31 с выходным лотком 32 в виде изогнутой балки прямоугольного сечения, подведенным к кассете. 16. При этом П-образные сердечники 33, поднимаясь по спиральному лотку (не показан) вибрационно-загрузочного устройства 31, ориентируются'друг за другом и, нависая перемычкой на выходном лотке 32, скользят по нему и ложатся в кассету 16 один на другой.In order to automate the charging process of the cartridge 16, the device is equipped with a vibration-loading device 31 with an output tray 32 in the form of a curved beam of rectangular cross section, connected to the cartridge. 16. In this case, the U-shaped cores 33, rising along a spiral tray (not shown) of the vibratory loading device 31, are oriented one after another and, hanging by a jumper on the output tray 32, slide over it and lie on the cassette 16 one on top of the other.
