Description
При этом сигнал на выходе логической схемы отсутствует.In this case, the signal at the output of the logic circuit is absent.
Когда микропрокладчик 11 прилетает в приемную коробку 12, то он пересекает магнитные линии катушки датчика 6 скорости микропрокладчика , наводит в ней ЭДС, котора через диод D2 поступает на базу транзистора Тг триггера 5, перевод в режим отсечки транзистор Т4 логической схемы НЕТ. Процесс контрол уточной нити закончен. При обрыве уточной нити сигнал с датчика 2 обрыва нити равен О, логическа схема на выходе .получает сигнал, привод щий в действие исполнительный механизм 8, который вызовет остановку ставка.When the microprojector 11 arrives at the receiving box 12, it crosses the magnetic lines of the coil of the microprojector 6 speed sensor, induces an emf in it, which through the diode D2 enters the base of the transistor Tg of the trigger 5, switching to the cut-off transistor T4 of the logic circuit NO. The weft control process is complete. When the weft yarn is broken, the signal from the yarn 2 sensor is equal to 0, a logic circuit at the output receives a signal that actuates the actuator 8, which will cause the rate to stop.
Таким образом, генератор тактовых импульсов дает начало контрол обрыва уточной нити в зеве основы, а датчик скорости микропрокладчика определ ет конец контрол уточной нити.Thus, the clock pulse generator initiates monitoring of the weft thread break in the base of the base, and the microprojector speed sensor detects the end of the control of the weft thread.
Устройство может найти применение на бесчелночных ткацких станках с частой перезаправкой его на выработку различных артикулов тканей.The device can be used on shuttleless weaving looms with frequent refilling to produce various articles of fabrics.
