Устройство работает следующим образом.The device operates as follows.

Установив пары стыковочных головок под необходимым углом cL· к поверхности стола 2, отрегулировав посред-'ством болтов 37, 38 усилия поджатия пружин 41, 42 в зависимости от типа заготовок и установив каретку 4, например, в крайнее левое положение, подают предварительно сцентрированную заготовку 58 на стол 2 до поверхности предварительно поднятой на необходимый уровень выравнивающей линейки 3. По другую сторону линейки 3 состыкованная полоса 58 в это же время совершает вместе с приподнятым транспортером 60 движение вниз-назад и также соприкасается своей кромкой с поверхностью выравнивающей линейки 3. После чего заготовку 58 и полосу 59 фиксируют на столе 2 специальными средствами (на показ).отводят линейку 3 вниз при помощи пневмоцилиндра 55 и включают привод перемещения стыковочных головок. При необходимости движения каретки 4, например, слева направо, втягивается правый шток пневмоцилиндра 35, θ левый выдвигается, при этом трос 24, создавая крутящий момент на блоке 21 вертикальной опоры 17, поджимает ограничитель 22 горизонтальной консоли 23 до упора 36 и одновременно перемещает каретку 4 вправо.Having set the pair of docking heads at the required angle cL · to the surface of the table 2, adjusted by means of bolts 37, 38 the preload forces of the springs 41, 42 depending on the type of workpieces and setting the carriage 4, for example, to the leftmost position, pre-centered workpiece is fed 58 on table 2 to the surface of the leveling rule 3 previously raised to the required level. On the other side of the line 3, the docked strip 58 at the same time makes a down-back movement together with the raised conveyor 60 and also contacts howling with the surface of the leveling ruler 3. After that, the workpiece 58 and the strip 59 are fixed on the table 2 by special means (to show). The ruler 3 is brought down using the pneumatic cylinder 55 and the drive for moving the docking heads is turned on. If it is necessary to move the carriage 4, for example, from left to right, the right rod of the pneumatic cylinder 35 is retracted, θ the left one extends, while the cable 24, creating torque on the block 21 of the vertical support 17, compresses the limiter 22 of the horizontal console 23 to the stop 36 and at the same time moves the carriage 4 to the right.

Следящий ролик 47, войдя в направляющий канал , образованный направляющими 48, 49 , задает окончательное направление движения стыковочным головкам вдоль линии стыка. Затем в зазор между кромками заготовок начинают входить узкое ребро 46 и узкая часть опоры 17. После чего в контакт со свисающими концами заготовок начинает входить направляющий лоток 45, приподнимая и выравнивая концы заготовок непосредственно перед зоной стыка, где их тут же начинают захватывать и сближать друг с другом конические колеса 5,6 и 7,8, осуществляя стыковку кромок. В конце процесса стыковки следящий ролик 47 выходит из направляющего канала, а стыковочные головки в это же время заканчивают стыковку заготовок.Tracking roller 47, entering the guide channel formed by the guides 48, 49, sets the final direction of movement of the connecting heads along the line of the joint. Then, a narrow rib 46 and a narrow part of the support 17 begin to enter the gap between the edges of the workpieces. After that, the guide tray 45 comes into contact with the hanging ends of the workpieces, lifting and aligning the ends of the workpieces directly in front of the joint zone, where they immediately begin to be gripped and brought together with the other, the conical wheels are 5.6 and 7.8, connecting the edges. At the end of the joining process, the follower roller 47 exits the guide channel, and the joining heads at the same time complete the joining of the workpieces.

Каретка U, дойдя до магнита 57,. останавливается, так как в это время правый шток пневмоцилиндра 35 находится в крайнем левом (втянутом) положении. После этого осуществляется расфиксация состыкованных заготовок и их отбор на поднимающийся транспортер 60.Затем шток пневмоцилиндра ' 55, выдвигаясь, подает линейку 3 вперед и вверх до появления ее над поверхностью стола 2. Подают следую-? щую заготовку на стол 2 до поверхности линейки 3, по другую сторону которой состыкованная полоса в это же время совершает вместе с приподнятым транспортером 60 движение внизназад и также соприкасается своей кромкой поверхности выравнивающей линейки 3. Одновременно с этим левый шток пневмоцилиндра 35 начинает втягиваться, а правый выдвигаться, левая ветвь троса 24 натягивается и начинает поворачивать блок 21 вертикальной опоры 17 на 180°, т.е. до тех пор, пока горизонтальная консоль 23 опрры 17 не упрется ограничителем 22 в упор 36 Это достигается благодаря тому, что магнит 57 создает посредством воздействия магнитного поля на коррус каретки 4 тормозящие усилия, за счет которых и осуществляется поворот стыковочных головок при неподвижной каретке 4. После поворота усилия тяги левого штока пневмоцилиндра 35 возрастают, и как только они превысят силы притяжения магнита 57, каретка 4 начнет обратное движение, т. е. влево до магнита 56, снова осуществляя стыковку. Цикл работы повторяется.Carriage U, reaching magnet 57 ,. stops, because at this time the right rod of the pneumatic cylinder 35 is in the extreme left (retracted) position. After this, the docked workpieces are unlocked and selected on a lifting conveyor 60. Then the pneumatic cylinder rod '55, moving forward, feeds the ruler 3 forward and up until it appears above the surface of the table 2. Serve the following-? the workpiece on table 2 to the surface of the ruler 3, on the other side of which the joined strip at the same time moves downward with the raised conveyor 60 and also touches the edge of the leveling ruler 3 with its edge. At the same time, the left stem of the pneumatic cylinder 35 begins to retract, and the right to extend, the left branch of the cable 24 is pulled and begins to rotate the block 21 of the vertical support 17 by 180 °, i.e. until the horizontal console 23 of the support 17 rests against the stop 22 against the stop 36 This is achieved due to the fact that the magnet 57 creates braking forces by applying a magnetic field to the carriage 4 corridor, due to which the docking heads are rotated when the carriage 4 is stationary. After the rotation, the thrust forces of the left rod of the pneumatic cylinder 35 increase, and as soon as they exceed the attractive forces of magnet 57, the carriage 4 will begin to move backward, i.e., to the left to magnet 56, again docking. The cycle of work is repeated.

Использование данного устройства при стыковке резинокордных заготовок позволит повысить надежность стыковки, благодаря линейному контакту роликов с полотном и возможности регулировки хода сближения кромок и усилий поджатия стыковочных головок к кромкам, и улучшить условия обслуживания операции стыковки, благодаря размещению основных механизмов под поверхностью стола, а следовательно, производительность процесса стыковки .The use of this device when joining rubber-cord blanks will improve the reliability of joining, due to the linear contact of the rollers with the blade and the ability to adjust the course of convergence of the edges and the efforts of pressing the joint heads to the edges, and improve the service conditions of the joining operation, due to the placement of the main mechanisms under the table surface, and therefore docking process performance.

After that, the workpiece 58 and the strip 59 are fixed on the table with 2 special means (for display), take the ruler 3 down using the pneumatic cylinder 55 and turn on the drive for displacement of the coupling heads. If the carriage 4 needs to move, for example, from left to right, the right rod of the pneumatic cylinder 35 is pulled in and the left one extends, while the cable 24, creating a torque on the block 21 of the vertical support 17, presses the limiter 22 of the horizontal console 23 against the stop BZ and simultaneously moves carriage 4 to the right. The follower roller 47, entering the guide channel formed by the guides 48, 49, sets the final direction of movement of the docking heads along the line of the joint. Then, a narrow edge 46 and a narrow part of the support 17 begin to enter the gap between the edges of the blanks. Then the guide tray 45 comes in contact with the hanging ends of the blanks, lifting and aligning the ends of the blanks directly in front of the joint zone, where they immediately begin to pick up and pull together with each other conical wheels 5,6 and 7,8, carried out the docking edges. At the end of the docking process, the follower roller 47 emerges from the guide channel, and the docking heads at the same time finish the docking of the blanks. Carriage 4, reach magnet 57 ,. stops as at this time the right-hand rod of the pneumatic cylinder 35 is on. It is in the extreme left (retracted) position. After that, the jointed blanks are uncoupled and selected for lifting trans-60 60. Then the pneumatic cylinder rod 55, advances, feeds the ruler 3 forward and upward until it appears above the surface of the table 2. The next workpiece is fed to the table 2 3, on the other side of which the docked strip at this time makes a downward movement together with the raised conveyor 60 and also touches its edge of the surface of the liner 3 with its edge. At the same time, the left rod of the pneumatic cylinder 35 begins retracted, and the right vydvigats, the left branch of the rope is tensioned and 2k starts turning unit 21 hydrochloric vertical support 17 by 180 °, i.e. until the horizontal console 23 of the oprra 17 is restrained by the restrictor 22 in the lane 36. This is achieved due to the fact that the magnet 57 creates, by means of a magnetic field on the corset of the carriage 4, the braking force is applied, due to which the docking heads are rotated Noah carriage k. After rotation, the forces of the hydraulic rod of the pneumatic cylinder 35 increase, and as soon as they exceed the attractive force of the magnet 57, the carriage k will begin the reverse movement, i.e., to the left until the magnet 5b, but dock again. The cycle of operation is repeated. Using this device when joining rubber-cord blanks will improve the reliability of the docking, due to the linear contact of the rollers with the web and the possibility of adjusting the approach of the edges and the efforts of pressing the docking heads to the edges, and improve the conditions for servicing the docking operation, by placing the main mechanisms under the table surface, and therefore docking performance.
