Изобретение относитс к машиностроению , в частности к конструкции устройств дл укладки микропроволоки на катушку.The invention relates to mechanical engineering, in particular, to the construction of devices for laying microwire on a coil.

Цель изобретени - повышение надежности за счет обеспечени точности перемещени каретки при реверсировании и исключени остановок и рывков при последнем .The purpose of the invention is to increase reliability by ensuring the accuracy of the carriage movement when reversing and eliminating stops and jerks during the latter.

На фиг. 1 показано предлагаемое устройство , общий вид; на фиг. 2 - разрез А-А на фиг. 1; на фиг. 3 - устройство при крайнем левом положении каретки, общий вид; на фиг. 4 - то же, при крайнем правом положении каретки.FIG. 1 shows the proposed device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the device with the leftmost position of the carriage, a general view; in fig. 4 - the same, with the extreme right position of the carriage.

Устройство содержит корпус 1, смонтированные в последнем направл ющие 2, размещенную на направл ющих 2 каретку 3 с раскладочным роликом 4, установленные на смонтированных в корпусе 1 ос х 5 приводной 6 и ведущий 7 шкивы, огибающие последние зубчатые ремни 8, а также узлы сцеплес между зубчатыми барабанами 10 и И, оказываетс в состо нии посто нного нат жени , при котором выбраны все зазоры. В результате соприкосновени каретки 3 с конечным выключателем 15 происходит от5 ключение электромагнитной сцепной муфты 12. Зубчатый барабан 10 расцепл етс с кареткой 3, а зубчатый барабан 11 сцепл етс с кареткой 3. Вращение его прекращаетс и каретка 3, сцепленна с нижней ветвьюThe device comprises a housing 1, guides 2 mounted in the latter, 2 carriage 3 placed on the guides 2 with a folding roller 4, mounted on the drive 6 mounted on the 1 x 5 axle and leading 7 pulleys, enveloping the last toothed belts 8, as well as the coupling nodes between the toothed drums 10 and I, is in a state of constant tension, in which all the gaps are selected. As a result of the contact of the carriage 3 with the limit switch 15, the electromagnetic clutch 12 is disconnected. The gear drum 10 disengages from the carriage 3, and the gear drum 11 engages with the carriage 3. Rotation stops it and the carriage 3 coupled to the lower branch

JQ ремн 8, начинает двигатьс влево. В момент переключени муфты 12 происходит мгновенное изменение направлени движени каретки 3, так как она через барабаны 10 и 11 находитс в попеременном сцеплении с нат нутым участком зубчатого ремн 8.JQ belt 8 starts moving to the left. At the moment of switching of the clutch 12, the direction of movement of the carriage 3 instantly changes, as it is through the drums 10 and 11 in alternating engagement with the tensioned portion of the toothed belt 8.

15 Величины предварительной настройки тормозных пар 13 барабанов 10 и 11 равны между собой, в св зи с тем, что тормозна пара 13 зубчатого барабана 10, не участву в изменении характера нат жени рабочего15 The values of the presetting of the brake pairs of the 13 drums 10 and 11 are equal to each other, due to the fact that the brake pair of the 13 gear drum 10 does not participate in changing the tension of the worker

ни каретки 3 с соответствующей ветвью Ј0 участка зубчатого ремн 8 при движении каремн 8, каждый из которых выполнен в виде установленного в каретке 3 вала 9, смонтированных на последнем зубчатых барабанов 10 и 11, электромагнитной сцепной муфты 12, один из элементов которой сочленен с валом 9, а другой - с кареткой 3, а также фрикционной тормозной пары 13, один из элементов которой соединен с валом 9, а другой - с кареткой 3. На корпусе 1 установлены конечные выключатели 14 и 15, а также направл ющие ролики 16.neither the carriage 3 with the corresponding branch Ј0 of the area of the toothed belt 8 when the carrnias 8 are moving, each of which is designed as a shaft 9 installed in the carriage 3, mounted on the last gear drums 10 and 11, an electromagnetic clutch 12, one of whose elements is articulated with the shaft 9, and the other with the carriage 3, as well as the friction brake pair 13, one of the elements of which is connected to the shaft 9, and the other with the carriage 3. On the body 1 there are limit switches 14 and 15, as well as guide rollers 16.

Устройство работает следующим образом.The device works as follows.

При включении привода (не показан) приводной шкив 6 получает вращение, сообща зубчатому ремню 8 перемещение. При этом каретка 3 находитс в крайнем левом положении. Нижн и верхн ветви ремн 8 движутс в противоположных направлени х. В левом крайнем положении конечный выключатель 14 замыкает цепь включени электромагнитной сцепной муфты 12.When you turn on the drive (not shown), the drive pulley 6 receives rotation, together with the toothed belt 8 move. In this case, the carriage 3 is in the extreme left position. The lower and upper branches of the belt 8 move in opposite directions. In the left extreme position, the limit switch 14 closes the switching circuit of the electromagnetic clutch 12.

Вращение зубчатого барабана 10 прекращаетс , а так как зубчатый ремень 8 не прижат к зубчатому барабану 10 направл ющими роликами 16, то каретка 3 начинает двигатьс по направл ющим 2 со скоростью движени ремн 8 вправо до соприкосновени каретки 3 с кончным выключателем 15.The rotation of the toothed drum 10 is stopped, and since the toothed belt 8 is not pressed against the guide rollers 16 to the toothed drum 10, the carriage 3 begins to move along the guides 2 at the speed of the belt 8 to the right until the carriage 3 contacts the end switch 15.

ретки 3 влево, устанавливаетс баланс в характере нагрузки на привод ведущего шкива 7. При достижении кареткой 3 конечного выключател 14 цикл повтор етс .3 to the left, a balance is established in the nature of the load on the drive pulley drive 7. When the carriage 3 reaches the end switch 14, the cycle is repeated.

Предлагаемое устройство позвол ет по- 25 высить надежность за счет обеспечени точности перемещени каретки при реверсировании и исключени остановок и рывков при последнем.The proposed device allows to increase reliability by ensuring the accuracy of the carriage movement when reversing and eliminating stops and jerks during the latter.
