Description

Известен механизм дл  продвижени  материала в швейной машине ,дл  шить  заготовок обуви, снабженный муфтой одностороннего свободного хода, приводимой в прерыв истое движение в одном направлении от колеблющегос  вала при помощи системы рычагов.A known mechanism for promoting material in a sewing machine for sewing shoe blanks, equipped with a one-way free-wheel clutch, which is interrupted in one direction from the oscillating shaft by means of a leverage system.

Эти механизмы обеспечивают лучшую маневренность при щитье фасонных заготовок по сравнению с обычным реечным механизмом продвижени  ткани. Тем не менее в двухигольных колонковых машинах они не примен ютс , так как наличие двух челноков затрудн ет их размещение .These mechanisms provide better maneuverability when sewing shaped blanks compared to the conventional rack and pinion mechanism for the promotion of fabric. However, they are not used in two-needle core machines, since having two shuttles makes them difficult to place.

Предлагаемый механизм позвол ет облегчить перемещение материала при работе на двухигольной колонковой машине за счет снабжени  механизма бесконечной металлической лентой, имеющей накатку. Лента проходит в верхней части механизма через вырезы в игольной пластинке, а в нижней части надета на шкив с. иголками, св занный с муфтой одностороннего действи .The proposed mechanism makes it easier to move the material when working on a two-needle core machine by supplying the mechanism with an endless metal band having a knurling. The tape passes in the upper part of the mechanism through the notches in the needle plate, and in the lower part is worn on the pulley c. needles associated with a one-way clutch.

На фиг. 1-изображен описываемый механизм; на фиг. 2 - схема муфты одностороннего свободного хода.FIG. 1 shows the described mechanism; in fig. 2 is a diagram of a one-way free clutch.

Рабочим органом механизма дл  продвижени  материала  вл етс  бесконечна  металлическа , имеюща  накатку лента /.The working body of the mechanism for promoting the material is an endless metallic, knurling tape.

Верхн   часть ленты проходит через вырезы в игольной пластинке 2, а нижн   надета на щ,кив 3 с иголками 4. Шкив св зан с муфтой 5 одностороннего свободного хода. Последн   приводитс  в прерывистое движение в одном направлении от колеблющегос  вала б при помощи системы рычагов 7. Вал 6 получает движение от вала 8 через регулируемый эксцентрик 9, соединительное звено 10 и кривошип /).The upper part of the belt passes through the notches in the needle plate 2, and the lower part is worn on the pin, nod 3 with needles 4. The pulley is connected to the coupling 5 of a one-way free wheeling. The latter is brought into intermittent motion in one direction from the oscillating shaft b by means of a system of levers 7. Shaft 6 receives motion from shaft 8 through an adjustable eccentric 9, a connecting link 10 and a crank /).

Таким образом, лента /, име  накатку и получа  прерывистое дви .жение, перемещает материал при работе на двухигольной колонковой мащине достаточно надежно.Thus, the tape /, having a knurling and getting an intermittent movement, moves the material when working on a two-needle core mask quite reliably.
