Description

Изобретение относитс к текстильному машиностроению и может использоватьс на ткацких станках.The invention relates to textile machinery and can be used on weaving machines.

Известен механизм привода ремиз к ткацкому станку, содержащий ведущий вал, прив . чмый от главного вала станка, планетарн .лй механизм, включающий водило и опорное г.олесо, попеременно взаимодействующие с фиксатором, управл емым от программного устройства, и кулачок, передающий движение ремизкам и кинематически св занный с водилом.The known mechanism of the drive remiz to the loom containing the drive shaft, pref. smack from the main shaft of the machine, the planetary mechanism, which includes the carrier and the supporting town, alternately interacting with the fixture controlled by the program device, and the cam transmitting the movement to the shafts and kinematically connected with the carrier.

Однако такой механизм не позвол ет вырабатывать ткани сложного переплетени с закрытым зевом, что особенно важно при выработке плотных тканей и тканей из ворсистой пр жи, склонной к слипанию.However, such a mechanism does not allow production of fabrics of complex interlacing with a closed throat, which is especially important when producing dense fabrics and fabrics from yarn yarn prone to sticking.

Цель изобретени - расщирение ассортимента вырабатываемой ткани при работе с закрытым зевом.The purpose of the invention is to expand the range of fabric produced when working with closed throat.

Дл этого кулачок имеет возможность качательного движени в зависимости от сигнала программного устройства, кинематически св зан с опорным колесом и снабжен запирающими собачками.For this, the cam has a swinging movement capability depending on the signal of the software device, is kinematically connected with the support wheel and provided with locking dogs.

На фиг. 1 изображен предлагаемый механизм , общий вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - разрез Б-Б на фиг. 1.FIG. 1 shows the proposed mechanism, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one.

Предлагаема конструкци имеет ведущий вал 1 по числу ремизных рам, жестко св занные центральные колеса 2, которые сцеплены с сателлитами 3. Последние насажекы подвижно на дистанционные втулки 4 осей 5, закрепленные в двух зубчатых колесах 6 и 7 водила, и сцеплены с внутренним зубчатым венцом опорного колеса 8. Опорное колесо 8 (см. фиг. 2) содержит внешний зубчатый венец 9, опорный диск 10, зубчатый диск 11, закрепленный на опорном диске с помощью заклепок 12 и имеющий впадины 13 дл остановки опорного колеса с помощью фиксатора 14. КолесоThe proposed structure has a drive shaft 1 according to the number of heddle frames, rigidly connected central wheels 2, which are coupled with satellites 3. The last attachments are movable onto spacers 4 axles 5 fixed in two gears 6 and 7 of the carrier and coupled to the inner gear the support wheel 8. The support wheel 8 (see Fig. 2) contains an external gear 9, a support disk 10, a gear disk 11 mounted on the support disk using rivets 12 and having depressions 13 for stopping the support wheel using a clamp 14.

Claims

The locking pins 14 and 17 are pivotally mounted on a fixed axis 18 and are connected by a lever gear 19 with the program mechanism. The ring gear 15 drove coupled through the parasitic gear 20 with the gear wheel 21, and the ring gear 9 of the support wheel 8 via the parasitic gear 22 is coupled with the wheel 23. The wheels 21 and 23 (see Fig. 3) are freely seated on the cam 24 and are connected to the latter with the help of dogs 25, hinged on pins 26 of cam 24. Dogs 25, coupled respectively with wheels 21 and 23, have opposite directions of action. The profile of the cam 24, which is movably mounted on the axle 27, is in contact with the rollers 28 and 29 of the lever 30, which is able to swing relative to the fixed axis 31. This device is placed in an oil bath insulated from the external environment. The proposed mechanism works as follows. The drive shaft 1 of the drive mechanism of the shaft drive receives a continuous rotation from the main shaft of the weaving machine. The central wheels 2, which are rigidly connected to the shaft 1, transmit continuous rotation to the satellites 3. The latter transmit movement to either the support wheel 8 or the carrier, depending on whether the carrier is fixed by the latch 16, or the support wheel is fixed by the latch 13. Rotation of the carrier or the supporting wheel the wheel 21 is transmitted through the parasitic gears 20 and 22 and through the pawl 25 to the cam 24, which drives the lever 30 and the linkage that follows from it to healings. FIG. 1 shows the working position of the mechanism when the retainer 17 holds the wheel 7 of the carrier, capturing its hollow 16. In this case, the wheels 6, 20 and 21 are stationary, and the support wheel 8 transmits an anti-clockwise rotation to the wheel 23 and through the paws the cam 24. The pawl 25 slides along the inner surface of the wheel 23. To change the direction of rotation of the cam 24, it is necessary that the latch 17 release the carrier and at the same time the latch 14 enters the depression 13 of the support wheel 8 (the position of the latch shown in thin lines) . The invention The drive mechanism of a shaft to a weaving machine, comprising a drive shaft driven from the main shaft of the machine, a planetary mechanism comprising a carrier and a support wheel alternately interacting with a lock controlled from a program device and a cam transmitting the movement to shims and kinematically connected with drove, characterized in that, in order to expand the range of tissue produced when working with a closed throat, the cam has the possibility of a swinging movement depending on the signal of the software mouth kinematically associated with the support wheel and provided with locking dogs.
