Description

Изобретение относится к текстильному машиностроению и может быть использовано на ткапких станках в механизмах набора полотна позитивного непрерывного действия. 'The invention relates to textile machinery and can be used on weaving machines in the mechanisms of a set of cloth positive continuous action. ''

Наиболее* близким к изобретению по I технической сущности и достигаемому результату является недосечный механизм ¹. ткацкого, станка, содержащий установленную на валу, связанном с механизмом на— ^,0бора полотна станка, муфту, ведущая ‘полумуфта которой установлена свободно ¹ и связана с приводом станка, а ведомая жестко, установленный на муфте недосечник, один элемент которого установлен на ведомой полумуфте и подпружинен к ней до упора пружиной кручения, а другой элемент - на ведущей полумуфте и подпружинен до упора в направлении ведомой полумуфгы, и связанное с механизмом пуска и останова станка средство управления недосечником, имеющие {рычаг и горку. Сцепление полумуфт осу ществляется пружиной за счет наличия торцовых зубцов на них£1].Closest to the invention according to I technical essence and the achieved result is a non-cutting mechanism ¹ . loom, machine tool, containing mounted on the shaft associated with the mechanism on ^{, 0} boron of the loom of the machine tool, the clutch, the leading 'half-clutch of which is installed loosely ¹ and connected to the machine drive, and the follower is rigidly mounted on the clutch undercutter, one element of which is mounted on the driven the coupling half and is spring-loaded to it until it stops by a torsion spring, and the other element is on the driving coupling half and spring-loaded to the stop in the direction of the driven coupling half, and the undercutter control device having a lever and a slide connected to the machine start and stop mechanism. The coupling of the coupling halves is carried out by the spring due to the presence of end teeth on them £ 1].

Недостатком этого механизма ткацкого станка является то, что усилие на рычаге переключения зависит от величины передаваемого полумуфтами крутящего момента. Чем больше передаваемый крутящий момент, тем с большим усилием должна действовать пружина, замыкающая полумуфты. При увеличении угловой скорости ведущей полумуфгы также требуется увеличение усилия пружины (имеет место проскальзывание полумуфт одно относительно другого, быстрый износ зубьев, их поломка).The disadvantage of this loom mechanism is that the force on the shift lever depends on the amount of torque transmitted by the coupling halves. The greater the transmitted torque, the more force the spring closing the coupling halves must act. With an increase in the angular velocity of the leading coupling half, an increase in the spring force is also required (there is a slip of the coupling half relative to one another, rapid wear of the teeth, their breakage).

Увеличение усилия пружины приводит к увеличению нагрузки в звеньях средства управления.The increase in spring force leads to an increase in the load in the links of the control means.

Устройство работает следующим образом.The device operates as follows.

От привода ткацкого станка цепной передачей (не показаны) посредством звездочки 5 получает вращательное движение полумуфта 3. Шток 6, находящийся в полумуфге 3, своей выступающей частью 11 взаимодействует с сектором 12, который, соприкасаясь с упором 18 (фиг. 2), приводит во вращательное движение против часовой стрелки полумуфту 4, вал 2, зубчатое колесо 16 и механизм набора полотна. Пружина кручения 14 взведена. Рычаг 10 не контактирует с кольцевой канавкой 19 полумуфты 3 и занимает положение Г (фиг. 3).From the drive of the loom, the chain transmission (not shown) through the sprocket 5 receives the rotational movement of the coupling half 3. The stem 6 located in the coupling half 3, with its protruding part 11, interacts with the sector 12, which, in contact with the stop 18 (Fig. 2), leads to counterclockwise rotation of the coupling half 4, the shaft 2, the gear 16 and the web setter. Torsion spring 14 cocked. The lever 10 does not contact with the annular groove 19 of the coupling half 3 and occupies the position G (Fig. 3).

При обрыве уточной нити валик 17, а вместе с ним и рычаг 10 поворачиваются против часовой стрелки (фиг. 2). Рычаг 10 контактирует с поверхностями кольцевой канавки 19 полумуфты 3, занимая положение П (фиг.З). Полуму^нта 3, вращаясь, подводит шток 6 к рычагу 10. Рычаг 10 своей горкой 9 взаимодействует со скосом 8 штока 6, перемещая последний вправо и отводя выступающую часть 11 штока 6 от сектора 12, шток 6 перестает контактировать с сектором 12, который под действием пружины кручения 14 поворачивается (фиг.З) по часовой стрелке до упора 15, полумуфта 4 останавливается, передача движения механизму набора товара прекращается.When the weft thread is broken, the roller 17, and with it the lever 10, rotate counterclockwise (Fig. 2). The lever 10 is in contact with the surfaces of the annular groove 19 of the coupling half 3, occupying the position P (Fig.Z). Half-moon 3, rotating, brings the rod 6 to the lever 10. The lever 10 with its slide 9 interacts with the bevel 8 of the rod 6, moving the latter to the right and moving the protruding part 11 of the rod 6 from sector 12, the rod 6 ceases to contact with sector 12, which under the action of the torsion spring 14 is rotated (Fig.Z) clockwise to the stop 15, the coupling half 4 is stopped, the transmission of movement to the set of goods is stopped.

При дальнейшем вращении полу муфты 3 шток 6 перестает контактировать с рычагом 10 и под действием пружины 7 перемещается влево (фиг. 1) до упора, занимая первоначальное положение. К концу завершения одного оборота выступающая часть 11 штока 6 вновь начинает контактировать с сектором 12, который первоначально движется в пазу полумуфты 4 до встречи с упором 18. Пооле этого полумуфта 4 приводится в цви| жение и передает это движение механиэму набора товара. Пружина 14 позволяет смягчить удар в момент встречи вы ст узнающей части 11 штока 6 с сектором 12. Отвод рычага .10 (поворот валика 17) от поверхности полумуфты 3 осуществляется механизмом пуска и останова станка в тот момент, когда нет взаимодействия рычага 10 с штоком 6.With further rotation of the floor of the coupling 3, the rod 6 ceases to contact the lever 10 and, under the action of the spring 7, moves to the left (Fig. 1) to the stop, taking its original position. By the end of the completion of one revolution, the protruding part 11 of the rod 6 begins to contact again with the sector 12, which initially moves in the groove of the coupling half 4 until it meets the stop 18. The floor of this coupling half 4 is brought in | living and transfers this movement to the mechanism of recruitment. The spring 14 allows you to soften the impact at the moment of meeting of the recognizing part 11 of the rod 6 with sector 12. The lever .10 (rotation of the roller 17) is removed from the surface of the coupling half 3 by the start and stop mechanism of the machine at the moment when there is no interaction of the lever 10 with the rod 6 .
