Description
(54) ПНЕВМАТИЧЕСКИЙ ДАТЧИК ОБРЫВА НИТИ(54) PNEUMATIC THREAD CIRCUIT SENSOR
1one
Изобретение относитс к средствам контрол и предназначено дл регистрации обрыва нити.The invention relates to control means and is intended to register a thread break.
Известен пневматический датчик обрыва нити, содержащий подающее и приемное сопла , расположенные по разные стороны контролируемой нити, причем входна часть подающего сопла св зана с источником давлени , а выходпа часть приемного сопла подключена к индикатору .A pneumatic thread break sensor is known, which contains a supply and a receiving nozzle located on opposite sides of the monitored thread, the input part of the supply nozzle is connected to a pressure source, and the output part of the receiving nozzle is connected to an indicator.
В известном датчике сжатый воздух из подающего сопла может отклонить нить и попасть в приемное сопло, вызвав ложное срабатывание датчика.In a known sensor, the compressed air from the feed nozzle can deflect the thread and get into the receiving nozzle, causing a false response of the sensor.
С целью повыщени точности контрол в предложенном датчике выходна часть подающего сопла выполнена в виде клиновидного паза, а входна часть приемного сопла - в виде усеченного конуса.In order to increase the accuracy of control in the proposed sensor, the output part of the feeding nozzle is made in the form of a wedge-shaped groove, and the input part of the receiving nozzle is in the form of a truncated cone.
На чертеже схематично изображен предложенный датчик.The drawing schematically shows the proposed sensor.
В корпусе 1 расположено подающее сопло 2, имеющее канал 3 дл подвода воздуха. Выходна часть сопла 2 выполнена в виде клиновидной канавки (паза) 4 с основанием 5. В корпусе 6 расположено приемное сопло 7 с каналом 8 приема воздуха. Входна часть сопла 7 выполнена в виде усеченного конуса 9, а выходна часть 10 соединена с индикатором (на чертеже не показан). Датчик работает следующим образом. Сжатый воздух подводитс к соплу 2 через канал 3. Контролируема нить (на чертеже пе показана) располагаетс в клиновидном пазу 4 вблизи основани 5. В результате взаимодействи нити с потоком воздуха, выход щим из канала 3, между питью и стенками клиновидного паза 4 возникает давление ниже атмосферного (разрежение), которое удерживает пить в клиновидной канавке и преп тствует попаданию воздуха в приемное сопло 7. При обрыве нити сжатый воздухIn the housing 1 there is a feed nozzle 2 having a channel 3 for supplying air. The output part of the nozzle 2 is made in the form of a wedge-shaped groove (groove) 4 with the base 5. In the case 6 there is a receiving nozzle 7 with an air intake channel 8. The input part of the nozzle 7 is made in the form of a truncated cone 9, and the output part 10 is connected to the indicator (not shown). The sensor works as follows. The compressed air is supplied to the nozzle 2 through the channel 3. The controlled thread (not shown in the drawing) is located in the wedge-shaped groove 4 near the base 5. As a result of the interaction of the thread with the air flow leaving the channel 3, pressure occurs between the drink and the walls of the wedge-shaped groove 4 below atmospheric (vacuum), which keeps drinking in the wedge-shaped groove and prevents air from entering the receiving nozzle 7. When the thread is broken, compressed air
поступает в канал 8 приемного сопла 7 и фиксируетс индикатором давлени . Усеченный конус 9 создает болееблагопри тные услови дл попадани сжатого воздуха в приемный канал 8 за счет уменьщени вли ни enters the channel 8 of the receiving nozzle 7 and is fixed by a pressure indicator. The truncated cone 9 creates more favorable conditions for the entry of compressed air into the receiving channel 8 by reducing the effect

Предложенный датчик может быть применен при контроле нити на щвейных машинах, намоточном оборудовании и т. д.The proposed sensor can be used to control the thread on the sewing machines, winding equipment, etc.
