Изобретение относитс к области автоматизации управлени химико-технологическими процессами, в частности процессом формовани химических волокон.This invention relates to the field of automating the control of chemical technological processes, in particular the process of forming chemical fibers.
Известен способ управлени процессом формовани химических волокон в зависимости от механических напр жений в свежесформованном волокне.A known method of controlling the process of forming chemical fibers, depending on the mechanical stresses in the freshly formed fiber.
Данный способ вл етс наиболее близким к изобретению по своей технологической сущности и достигаемому результату.This method is closest to the invention in its technological essence and the achieved result.
Недостатком его вл етс неточность управлени вследствие того, что канал управлени процессом ло параметрам осадительной ванны имеет значительную нерционность .The disadvantage of it is the inaccuracy of control due to the fact that the process control channel of the parameters of the precipitation bath has considerable inactivity.
Целью данного изобретени вл етс повышение точности управлени .The purpose of this invention is to improve the accuracy of control.
Это достигаетс тем, что определ ют частоту возникновени намотов жгута на вальцы и в зависимости от механических напр жений в свежесформованном волокне и частоты возникновени намотов производ т регулировку скорости вращени галет пр дильного агрегата.This is achieved by determining the frequency of the windings of the rope on the rolls and, depending on the mechanical stresses in the newly formed fiber and the frequency of the occurrences of the windings, adjust the speed of rotation of the spinning wheel of the spinning unit.
На чертеже представлена схема осуществлени способа управлени процессом формовани химических волокон.The drawing shows an embodiment of a method for controlling the process of forming chemical fibers.
Технологи способа заключаетс в следующем .The process technology is as follows.
Вискоза по трубопроводу 1 проходит через фильеру 2 и, попада в раствор осадительной ванны 3, коагулирует. Сформованна нить принимаетс галетами 4. Нити от р да фильер собираютс в жгут 5, который поступает на головные вальцы б, а затем на хвостовые вальцы 7. Галеты 4, головные 6 и хвостовые 7 вальцы имеют разную относительно друг друга скорость вращени ,Viscose through pipeline 1 passes through a die plate 2 and, falling into the solution of the precipitation bath 3, coagulates. The formed thread is accepted by the fillets 4. The filaments from the row of spinnerets are assembled into bundle 5, which is fed to the head rollers b, and then to the tail rollers 7. Galetes 4, head 6 and tail 7 rollers have different rotational speeds relative to each other,
обеспечива нат гивание жгута.providing tension on the harness.
Посредством датчика 8 определ ют механические напр жени в свел есформованном волокне - жгуте 5. Начало образовани намотов на головных б и хвостовых 7 вальцахBy means of the sensor 8, mechanical stresses are determined in the co-formed unformed fiber, tow 5. The beginning of the formation of windings on the head b and tail 7 rollers
сигнализируетс датчиками 9. Выходы датчиков 9 соединены через элемент ИЛИ со входом дискретно-аналогового преобразовател 10 частоты, который выдает сигнал, пропорциональный частоте образовани намотов . Сигналы с преобразовател 10 и датчика 8 мехаиических напр жений волокна поступают на вход вычислительного блока И,.где расчитываетс оптимальное значение скорости вращени галет, и вычисленноеit is signaled by sensors 9. The outputs of sensors 9 are connected via an OR element to the input of a discrete-analog frequency converter 10, which outputs a signal proportional to the frequency of windings. The signals from the converter 10 and the sensor 8 of the mechanical fiber voltage are fed to the input of the computing unit AND, where the optimal value of the speed of rotation of the wafers is calculated, and the calculated
значение выставл етс с помощью исполнительного механизма 12 и вариатора 13.the value is set using the actuator 12 and the variator 13.
