В продольных пазах секторов 13 шарнирно установлены двуплечие рычаги 23, на одних плечах которых смонтированы ролики 24, а другие обтянуты резиновой оболочкой 25.A device for assembling tires of pneumatic tires contains longitudinal beams I mounted between end disks 2, which are mounted on the shaft 3. Beams 1 are provided with protrusions 4 with inclined sections interacting with the conical surface of axially movable bushings 5. On the side walls of each beam 1 are fixed plates copiers 1 with inclined sections 7. The longitudinal beams 1 are kept from axial movement by the rollers 8. In addition, the ends of the beams 1 are located in the radial grooves of the disks 2 and the flanges of the bushes 5. On the beams 1 is mounted ¹ axially movable sectors 9, 10, II, 12 and 13, which are interconnected with each other and with the flanges of the bushings 5 by means of the rods 14. On the split cylindrical shells 15, covering the sectors 9, 11 and 12, are smoothed ·: molded ring pneumatic chambers 16, and segment plates 17 are fixed on sectors 9, 11 and 12. On the shells 18 covering sectors 10 and 13, auxiliary forming ring pneumatic chambers 19 and 20 are mounted. Shells 15 are located telescopically with respect to segment plates 17 and shells 18. Supply of compressed air to the pneumatic chamber M 16, 19 and 20 are carried out by flexible hoses 21 located as in the grooves 22 of the longitudinal beams 1.

Сборка покрышек на описываемом устройстве осуществляется следующим образом.The tire assembly on the described device is as follows.

На поверхность секторов (см. фиг. 4) накладывают слои корда 30, образующие браслет, затем заводятся бортовые кольца 31 (см. фиг. 5) концентрично секторам. После этого втулки 5 посредством стерж- *0 ней 26 и 27 (фиг. 1) и тяг 28 и 29 сближаются. При этом выступы 4 балок 1, скользя по конусным участкам втулок 5, радиально раздвигают балки 1, в результате диаметр устройства увеличивается (см. фиг. 6). Происходит посадка бортовых колец 31 в канавки, образованные кромками пневмокамер 16 и выступами сегментных пластин 17. При этом также происходит разрезание образованного на барабане браслета на несколько равных по м ширине браслетов посредством ножей 32.On the surface of the sectors (see Fig. 4) lay the cord layers 30 forming a bracelet, then the side rings 31 (see Fig. 5) are wound concentrically to the sectors. After that, the sleeve 5 by means of the rod * 0 of it 26 and 27 (Fig. 1) and rods 28 and 29 are brought together. In this case, the protrusions 4 of the beams 1, sliding along the conical sections of the sleeves 5, radially extend the beams 1, as a result, the diameter of the device increases (see Fig. 6). The side rings 31 are planted in the grooves formed by the edges of the pneumatic chambers 16 and the protrusions of the segment plates 17. In this case, the bracelet formed on the drum is also cut into several bracelets equal in width to the m by means of knives 32.

В пневмокамеры 16, 19 и 20 (см. фиг. 7) подают сжатый воздух. Происходит формование каркасов и предварительный заворот кромок браслетов на бортовые кольца. _siПри дальнейшем движении втулок 5 выступы 4 скользят по цилиндрическим участкам втулок 5 (диаметр барабана остается неизменным). Втулки 5, взаимодей ствуя с секторами 13 (см. фиг. 8), перемещают их в направлении к средней камере 16. Секторы 13 перемещают секторы 9, 10, 11 и 12 к средней основной пневмокамере 16. При этом сегментные пластины 17, телескопически перемещаясь относительно обечаек 15 и 18, сближаются между собой, сближая пневмокамеры 16, 19 и 20. При перемещении роликов 24 по наклонным участкам 7 плечи рычагов 23 устанавливаются перпендикулярно сборочной поверхности и служат с оболочками 25 упорами для пневмокамер 19 с целью направленного раздутия их. При сближении пневмокамер 16, 19 и 20 происходит окончательный заворот кромок на бортовые кольца и дублирование их с каркасом. После этого секторы 9, 10, 11 и 12 посредством втулок и стержней 14 отводят в исходное положение, из пневмокамер 19 и 20 (см. фиг. 9) выпускают воздух. На образованные каркасы накладывают протекторы 33. После этого выпускают воздух из пневмокамер ί6 (см. фиг. 10), втулки 5 возвращают в исходные положения. Устройство уменьшается в диаметре, производится съем собранных покрышек. После чего цикл повторяется.Compressed air is supplied to the pneumatic chambers 16, 19 and 20 (see FIG. 7). The frames are formed and the bracelets are pre-turned onto the side rings. _si With further movement of the sleeves 5, the protrusions 4 slide along the cylindrical sections of the sleeves 5 (the diameter of the drum remains unchanged). The bushings 5, interacting with the sectors 13 (see Fig. 8), move them towards the middle chamber 16. Sectors 13 move the sectors 9, 10, 11 and 12 to the middle main air chamber 16. In this case, the segment plates 17 are telescopically moving relative to the shells 15 and 18, they approach each other, bringing together the pneumatic chambers 16, 19 and 20. When moving the rollers 24 along the inclined sections 7, the arms of the levers 23 are installed perpendicular to the assembly surface and serve with the shells 25 as stops for the pneumatic chambers 19 for the purpose of their directed swelling. When the pneumocameras 16, 19 and 20 approach each other, the edges are finally turned on to the side rings and duplicated with the frame. After this, sectors 9, 10, 11 and 12 are removed by means of bushings and rods 14 to their initial position, air is released from the pneumatic chambers 19 and 20 (see Fig. 9). Protectors 33 are applied to the formed frames. After that, air is released from the pneumatic chambers ί6 (see Fig. 10), the bushings 5 are returned to their original positions. The device is reduced in diameter, the assembled tires are removed. Then the cycle repeats.

Данная конструкция устройства обеспечивает повышение производительности процесса сборки покрышек за счет того ,что на нем осуществляется одновременная сборка нескольких покрышек.This design of the device provides an increase in the performance of the tire assembly process due to the fact that several tires are assembled simultaneously on it.
