Description
Изобретение относитс к области текстильной промышленности и может быть использовано на бесчелночных ткацких станках , где производитс прокидка уточных нитей г азных цветов.The invention relates to the field of the textile industry and can be used on shuttleless weaving machines, where weft weaving of filament colors is produced.
Известен механизм смены утка дл бесчелночного ткацкого станка, содержащий поворотный сектор с двум нитеподавател ми и передаточный валик с подпружиненным роликом , соединенный посредством кинематической цепи с зевообразующим механизмом станка 1.A known weft-changing mechanism for the shuttleless loom, comprising a rotary sector with two thread suppressors and a transfer roller with a spring-loaded roller, connected by means of a kinematic chain to the shed-forming mechanism of the machine 1.
Недостатком известного механизма вл етс сложность из-за наличи мальтийского креста и цепи кулачковых звеньев разного профил , снижающа надежность работы механизма и увеличивающа врем наладки и ремонта.A disadvantage of the known mechanism is the complexity due to the presence of a Maltese cross and a chain of cam links of different profiles, which reduces the reliability of the mechanism and increases the time of adjustment and repair.
Целью изобретени вл етс упрощение конструкции механизма при сохранении высокой скорости работы и большого раппорта переплетений вырабатываемой .The aim of the invention is to simplify the design of the mechanism while maintaining a high speed of work and a large rapport of weaves produced.
Это достигаетс тем, что кинематическа цепь предлагаемого механизма смены утка снабжена установленным на оси в стойке кулачком , взаимодействующим с роликом передаточного валика, и шатуном, установленным между кулачком и зевообразующим механизмом .This is achieved by the fact that the kinematic chain of the proposed duck changer mechanism is equipped with a cam mounted on an axis in a rack, interacting with the transfer roller roller, and a connecting rod mounted between the cam and the shed forming mechanism.
Кулачок имеет два рабочих участка профил , соответствующих двум рабочим паюжени м шатуна.The cam has two working sections of the profile corresponding to two working connecting rod points.
На фиг. 1 схематически изображен предлагаемый механизм, общий вид; на фиг. 2 - качающийс кулачок.FIG. 1 schematically shows the proposed mechanism, a general view; in fig. 2 - swing cam.
Поворотный сектор I укреплен на валике 2 в стойке 3. Поворотный сектор, несет нитеподаватели 4. Привод управлени мехаиизмом смены утка осуществлен от зевообразующего механизма 5. В программонос щем картоне 6 просечены отверсти 7 в соответствии с требуемой программой смены утка. Дл привода механизма исгюльзована крайн позици рычажной системы каретки и соот ветственно крайн дорржка картона 6. Шатун 8 кинематической цепи посредством щарнира 9 сочленен с качающимс кулачком iO. Кулачок установлен на оси 11 в стойке. Количество рабочих участков кулачкаRotary sector I is mounted on roller 2 in rack 3. Rotary sector is carried by thread guides 4. The weft changer control drive is implemented from the shedding mechanism 5. In the program carrier cardboard 6, holes 7 are cut through in accordance with the required weft change program. For the drive of the mechanism, the extreme position of the lever system of the carriage and, accordingly, the extreme dorrzhka cardboard 6 are used. The connecting rod 8 of the kinematic chain through joint 9 is articulated with the swinging cam IO. The cam is mounted on axis 11 in the rack. Number of cam working areas
(фиг. 2), обозначенных на чертеже буквами а и б, равно двум положени м щатуиа 8. С кулачком 10 контактирует ролик 12, подпружиненный пружиной 13. Ролик св зан с передаточным валиком 14, который в свою(Fig. 2), indicated in the drawing by the letters a and b, is equal to two positions of the lever 8. With the cam 10 contacts the roller 12, which is spring-loaded 13. The roller is connected with the transfer roller 14, which in its
