Изобретение относитс к текстильному машиностроению и касаетс конструкции устройства дл подачи уточной нити к бесчелночному ткацкому станку. ,This invention relates to textile machinery and relates to the construction of a device for feeding a weft yarn to an shuttleless loom. ,
Известно устройство дл подачи уточной нити к ткацкому станку, содержащее нитенакопительную камеру/ соединенную на входе с форсункой,и компенсационную камеру, соединенную на ввисоде с пневматическим тормрзом уточной нити D- . :A device for feeding a weft yarn to a weaving machine, containing a thread-accumulating chamber / connected at the inlet with a nozzle, and a compensation chamber connected at the entrance to the pneumatic braking of the weft yarn D-, is known. :
Недостатком этого устройства вл етс то, что оно не позвол ет поддерживать посто нное, нат жение УТОЧ.НОЙ 15 нити во врем прокидки ее в зеве на бесчелночных ткацких станках с микрочелноками . Кроме того, встречные воздушные потоки в камерах создают пушение нити и повышают ее обрывность. 20The disadvantage of this device is that it does not allow to maintain a constant tension of the SPECIAL 15 thread during passing it in the throat on shuttleless weaving machines with microchannels. In addition, the oncoming air flow in the chambers creates a thread puff and increases its breakage. 20
Цель изобретени - снижение обрывности уточной нити и повышение надежности ее прокладывани на станке.The purpose of the invention is to reduce the breakage of the weft yarn and increase the reliability of its laying on the machine.
Указанна цель достигаетс тем, что устройство имеет тормозной эле- 25 мент, размещенный на выходе нитенакопительной камеры, при этом оси компенсационной и нитенакопительной камер размещены под углом одна к другой .30This goal is achieved by the fact that the device has a brake element placed at the exit of the storage chamber, while the axes of the compensation and storage accumulation chambers are placed at an angle to one another. 30
На чертеже изображено устройство.The drawing shows the device.
Устройство дл подачи уточной нити к ткацкому станку содержит питательную камеру 1, на поверхности которой выполнены отверсти 2. На входе нитенакопительной камеры 1 смонтирована форсунка 3, а на выходе - механический тормоз 4.The device for feeding the weft yarn to the loom contains a feeding chamber 1, on the surface of which holes 2 are made. At the inlet of the thread-collecting chamber 1, the nozzle 3 is mounted, and at the exit there is a mechanical brake 4.
Под углом от О до 90 к нитенакопительной камере 1 расположена компенсационна камера 5, имеюща также на своей поверхности отверсти 6, а на выходе - тормозной элемент 7, выполненный пневматическим. Уточна нить 8 с бобины 9 заправлена в нитенакопительную 1 и нитекомпенсационную 5 камеры и периодически захватываетс прокладчиком 10.At an angle from 0 to 90 to the accumulation chamber 1, there is a compensation chamber 5, which also has openings 6 on its surface, and at the exit is a pneumatic brake element 7. The weft thread 8 from the reel 9 is threaded into the thread-storage 1 and the thread-compensating camera 5 and is periodically captured by the plotter 10.
Работает устройство следующим образом .The device works as follows.
Уточна нить 8 сматываетс с бобины 9 воздушным потоком, образованным форсункой 3, и поступает в нитенакопительную камеру 1, где она укладываетс в форме витков или петель, в зависимости от профил поперечного сечени камеры.The weft thread 8 is wound from the bobbin 9 by the air stream formed by the nozzle 3 and enters the thread-storage chamber 1, where it is laid in the form of turns or loops, depending on the cross-sectional profile of the chamber.
Сжатый воздух, выход в отверсти 2, прижимает витки накопленной нити 8 к стенкам камеры 1, предотвраща Compressed air, exit into the holes 2, presses the turns of the accumulated thread 8 to the walls of the chamber 1, preventing
