Abstract

The delivery unit has a delivery roller (1) and a pressure roller (2). The pressure roller (2) is mounted in a leg (4) which is pivotable about a pivot point (8). The leg is connected to an arm (5). A thread guide (6) is located at one end of the arm (5) and a weight (7) is located in the region of the opposite end of the arm (5). The thread loops round the delivery roller (1) and the pressure roller (2). The pivot point (8) and the axis of the pressure roller (2) define a straight line X-X. When the unit is in operation, the axes of the pressure roller (2) and of the delivery roller (1) define a further straight line Y-Y, the said two straight lines forming an angle alpha . The pressure roller (2) is pressed against the delivery roller (1) as a result of the tension of the thread. If the thread tears, the weight (7) causes the arm (5) to pivot and the pressure roller (2) to lift off from the delivery roller (1). This very simple construction works reliably and results in fewer thread breaks than hitherto. <IMAGE>

Description

Нить 6,огиба  приводной цилиндр 5 и валик 1 и проход  через нитепроводник 8, поступает к початку 15, гд она скручиваетс  и перемещающимс  по кольцу 16 бегунком . 17 раскладызаетс  при наматывании на початке, Дри воздействии нити за счет нат жени  на нитепроводник рычаг 2 грузом 9 поворачиваетс  относительно оси 10 валик 1 прижимаетс  к цилиндру 5 и обеспечивает принудительную подачу нити со скоростью, равной линейной скорости приводного цилиндра 5, Отношение величины нат жени  нити в зоне между валиком и паковкой к силе прижима валика к цилиндру мень ше коэффициента трени  нити о цилинд и позтому скорость подачи нити равна линейной скорости цилиндра. Увеличе ние нат жени  нити вызывает пр мо пропорциональное увеличение прижима валика к цилиндру. В.случае обрыва нити при отсутствии ее нат жени  вследствие нарушени  равновеси  прутка 7 и рычага 2 последние поворачиваютс  по часовой стрелке. При этом несущее валик 1 плечо рычага 2 поднимаетс  и вгипик 1 отходит от приводного цилиндра, вследствие чего прекращаетс  принудительна  подача нити. После устранени  обрыва нити под действием ее нат жени  рычаг с прутком поворачивеиотс  в рабочее положение , Вс1лик прижимаетс  к цилиндру, и нить снова подаетс  к початку. Линейна  зависимость между силой прижима валика к цилиндру и нат жени нити позвол ет выполнить валик легким и подавать нити различных видовThe thread 6, the bending of the drive cylinder 5 and the roller 1 and the passage through the thread guide 8, goes to the cob 15, where it is twisted and is slid along the ring 16. 17 unfolds when winding on the cob, Driving the thread due to tension on the thread conductor lever 2 with the load 9 rotates about axis 10 roller 1 is pressed to the cylinder 5 and provides a forced feed of the thread with a speed equal to the linear speed of the drive cylinder 5, in the area between the roller and the packing to the force of the roller against the cylinder, the coefficient of friction of the thread on the cylinder is lower and, therefore, the feed rate of the thread is equal to the linear speed of the cylinder. Increasing the thread tension causes a directly proportional increase in the clamping of the roller to the cylinder. B. The case of thread breaking in the absence of tension due to an imbalance of the rod 7 and the lever 2 rotates clockwise. At the same time, the carrier roller 1, the lever arm 2 rises and the grip 1 departs from the drive cylinder, as a result of which the forced feeding of the thread stops. After the thread breakage is eliminated under the action of its tension, the lever with the rod turns into the working position, all the pressure is pressed against the cylinder, and the thread is again fed to the bobbin. The linear relationship between the force of pressing the roller to the cylinder and the tension of the thread allows the roller to be made easy and to feed different types of threads.
