Изобретение относитс  к оборудованию Шинной и резинотехнической промышленности и может быть использовано при стыковке резинокордных заготовок, например при изготовлении брекерных браслетов и сборке каркасов шин.The invention relates to equipment Tire and rubber industry and can be used when joining rubber-cord blanks, for example in the manufacture of belt bracelets and assembly of tire carcasses.

Известно устройство дл  стыковки, содержащее два зубчатых стыковочных ролика , закрепленных под углом на руко тке 1.A device for docking is known, comprising two notched docking rollers mounted at an angle on the handle 1.

Известное устройство не обеспечивает необходимого равнопрочного качества при стыковке (которую осуш,ествл ют при наклонном в сторону движени  положении руко тки), так как положение руко тки зафиксировать рукой под определенным посто нным углом практически невозможно, что приводит в процессе стыковки к изменению величины смепхени  точки наименьшего сближени  (контакта) зубчатых роликов от точек начального контакта этих роликов с полотном, кроме того, при незацеплениом друг с другом вращении роликов кромки полотна свести вплотную невозможно и это требует усилени  стыка резиновой ленточкой и предварительного выдергивани  одной нити металлокорда из кромки.The known device does not provide the required equal strength when docking (which is dried when the handle is tilted in the direction of movement), since it is almost impossible to fix the position of the handle by hand at a certain constant angle, which leads to a change in the difference value closest contact (contact) of the toothed rollers from the points of initial contact of these rollers with the web, moreover, when the rollers of the web edge do not cling to each other, draw close impossible and this requires enhancing the joint rubber ribbon and prior pulling one strand of steel cord from the edge.

Известно устройство дл  стыковки резинокордных заготовок, содержащее стол дл  стыковки, подвижную вдоль последнего каретку и последовательно установленные посредством опор на каретке пару стыковочных роликов, расположенных под углом относительно друг друга и под углом к поверхности стЬла, и прикаточные ролики 2. В таком устройстве стыковочные ролики выполнены гладкими, что не обеспечивает плотное сведение стыкуемых кромок, поскольку контакт роликов с кромками точечный и точки контакта несколько отсто т от линии стыка, где кромки имеют возможность выдавливатьс  вверх. Кроме того, такое устройство с двум  парами роликов может быть приемлемо только дл  одного типоразмера заготовок и непригодно дл  других заготовок с различным межкромочным зазором, поскольку не предусмотрена регулировка угла наклона стыковочных роликов к полотну, что непосредственно вли ет на ширину захвата ими кромочных участков и величину хода сближени  кромок, т. е. на межкромочный зазор перед стыковкой .A device for joining rubber-cord blanks is known, comprising a table for docking, a carriage moving along the last carriage and successively installed by means of supports on the carriage a pair of docking rollers arranged at an angle relative to each other and at an angle to the surface of the bed, and press rollers 2. In such a device docking rollers are made smooth, which does not ensure a tight convergence of the joined edges, since the contact of the rollers with the edges is point and the contact points are somewhat separated from the butt line, where the edges hav e the opportunity vydavlivats up. In addition, such a device with two pairs of rollers may be acceptable only for one size of the blanks and unsuitable for other blanks with different inter-edging clearance, since no adjustment of the angle of inclination of the butt rollers to the web is provided, which directly affects the width of the edges and the size the course of the approaching of the edges, i.e., the inter-edging gap before docking.

Целью изобретени   вл етс  повышение качества стыка.The aim of the invention is to improve the quality of the joint.

Данна  цель достигаетс  тем, что в устройстве, содержащем стол дл  стыковки , подвижную вдоль последнего каретку и последовательно установленные посредством опор на каретке пару стыковочныхThis goal is achieved by the fact that in the device containing a docking table, a carriage moving along the last carriage and successively installed by means of supports on the carriage

роликов, расположенных под углом относительно друг друга и под углом к поверхности стола, и прикаточные ролики, согласно изобретению стыковочные ролики выполнены в виде взаимодействующих друг с другом конических зубчатых колес, боковые поверхности которых имеют ооращенные к последним большим основанием дополнительные конические участки, образующие которых расположены под углом к перпендикул рному линии стыка направлению, причем последний выбран в пределах 1-10°.rollers arranged at an angle relative to each other and at an angle to the surface of the table, and the stitching rollers according to the invention docking rollers are made in the form of bevel gears interacting with each other, the lateral surfaces of which have additional conical sections oriented towards the last large base at an angle to the perpendicular line of the junction to the direction, the latter being selected in the range of 1-10 °.

Кроме того, консоль опоры стыковочных роликов установлена на консоли опоры прикаточпых роликов посредством хомута .и клинового зажима.In addition, the support bracket for the docking rollers is mounted on the support bracket for the stitching rollers by means of a yoke and a wedge clamp.

При этом межосевой угол конического зацеплени  выбран в пределах 95-120°. Перед стыковочными роликами по ходу движени  на их опоре закреплена ограничительна  планка со скругленным концом, взаимодействующим с поверхностью заготовок . Поверхность дополнительных конических участков выполнена с сетчатыми насечками в виде усеченных четырехгранных пирамид, угол схождени  граней которых выбран в пределах 45-60°.At the same time, the center angle of the conic engagement is selected in the range of 95-120 °. In front of the docking rollers, a restrictive bar with a rounded end interacting with the surface of the workpieces is fixed on their support along the movement. The surface of additional conic sections is made with mesh notches in the form of truncated tetrahedral pyramids, the angle of convergence of the faces of which is chosen in the range of 45-60 °.

Устройство содержит стол (не показан) дл  стыковки и подвижную вдоль него каретку , образованную двум  Г-образньши опорами 1 и 2. Опора 1 опираетс  на пару стыковочных роликов 3, расположенных под углом 7 относительно друг друга и под углом а к поверхности стола. Межосевой угол Y выбирают в пределах 95-120°.The device comprises a table (not shown) for docking and a carriage moving along it, formed by two L-shaped supports 1 and 2. The support 1 rests on a pair of connecting rollers 3 located at an angle 7 relative to each other and at an angle a to the surface of the table. The center angle Y is chosen in the range of 95-120 °.

Опора 2 опираетс  на прикаточные ролики 4, выполненные в виде шарикоподщипников , посаженных на оси 5.Bearing 2 rests on stitching rollers 4, made in the form of ball bearings, seated on axis 5.

Ролики 3 выполнены в виде взаимодействующих друг с другом конических зубчатых колес, боковые поверхности которых имеют дополнительные конические участки а. Образующие данных участков а расположены под углом р к перпендикул рному линии стыка направлению. При этом угол р выбрап в пределах 1 -10°. Поверхности дополнительных конических участков а имеют сетчатые насечки, выполненные в виде усеченных четырехгранных пирамид , например, высотой ,4 мм; шагом расположени  мм и углом схождени  граней б 45-60°. На опоре 1 выше конических колес 3 закреплена упруга  ограничительна  плапка 6 со скругленным передним конца б, взаимодействующим с поверхностью заготовок и предохран ющим стыкуемые кромки от волнообразных деформаций Б момент стыковки.The rollers 3 are made in the form of interacting with each other bevel gears, the side surfaces of which have additional conical sections a. The generators of these areas are located at an angle p to the direction perpendicular to the line of the junction. In this case, the angle p is chosen in the range of 1-10 °. The surfaces of additional conic sections a have mesh notches made in the form of truncated tetrahedral pyramids, for example, 4 mm high; mm spacing and the angle of convergence of the faces b 45-60 °. On support 1 above the bevel gears 3, a resilient, restrictive pad 6 is fixed with a rounded front end b, which interacts with the surface of the workpieces and protects the joined edges from the undulating deformations B of the moment of docking.

Консоль опоры 2 закреплена с возможностью продольного перемещени  относительно консоли опоры 1, выполненной, например в виде хомута 7 с клиповым зажимом 8, что позвол ет регулировать угол а, например, в пределах от 45 до 60° в зависимости от разновидности заготовок. На опоре 2 смонтирована руко тка 9. Устройство работает следующим образом .The console of the support 2 is fixed with the possibility of longitudinal movement relative to the console of the support 1, made, for example, in the form of a collar 7 with a clip clamp 8, which makes it possible to adjust the angle a, for example, in the range from 45 to 60 ° depending on the type of blanks. On support 2, a handle 9 is mounted. The device operates as follows.

Установив опору 1 под необходимым (45-60°) углом а к поверхности заготовок 10, И, лежащих на стыковочном столе, давлением на руко тку 9 перемещают стыковочное устройство вдоль стыкуемых кромок. Стыковочные ролики 3 начинают контактировать с заготовками 10, И в точке Н, где колеса еще не зацеплены друг с другом, но благодар  их вращению с одновременнымHaving installed the support 1 at the required angle (45-60 °) and to the surface of the blanks 10, I, lying on the docking table, the docking device is moved along the joined edges by applying pressure to the handle 9. Docking rollers 3 begin to contact with the workpieces 10, And at the point H, where the wheels are not yet engaged with each other, but due to their rotation with simultaneous

сближением в точке /С (точка максимального контакта зубьев конических колес) кромки заготовок 10, 11 также начинают сближатьс  и стыковатьс  друг с другом, а прикаточные ролики 4 сглаживают и прикатывают неровности стыка. При этом благодар  зубчатому зацеплению, существующему на нижнем участке колес, кромки сближаютс  и одновременно поджимаютс  сверху, предохран  сь тем самым от выдавливани  вверх по линии стыка. Благодар  расположению образующих дополнительных конических участков а под углом р к перпендикул рному линии стыка направлению контакт роликов 3 с заготовками 10,By approaching at point / C (the point of maximum contact between the teeth of the bevel gears), the edges of the workpieces 10, 11 also begin to approach and join each other, and the stitching rollers 4 smooth and roll the unevenness of the joint. In this case, due to the gearing that exists on the lower portion of the wheels, the edges approach each other and simultaneously press down from the top, thereby preventing squeezing up along the intersection line. Due to the location of the forming additional conic sections a at an angle p to the perpendicular line of the joint, the direction of the contact of the rollers 3 with the workpieces 10,

И (в пределах регулируемой величины угла а) на дуге НК. происходит примерно по пр мой линии и более всего в точке Я. Кроме того, благодар  сетчатым насечкам на поверхности конических участков а этотAnd (within the limits of the adjustable value of the angle a) on the NC arc. occurs approximately along a straight line and most of all at point I. In addition, thanks to the mesh notches on the surface of the conical sections, and this

контакт более надежен и сближение кромок осуществл етс  с большим усилием. В процессе стыковки ограничительна  планка 6, перемеща сь впереди колес 3 по кромкам , передним концом предохран ет стыкуемые кромки от волнообразных деформаций , а задний ее конец служит кожухом, предохран ющим пальцы стыковщика от вращающихс  колес. По окончании стыковки заготовок 10 и И устройство переноситс  на следующие заготовки и цикл повтор етс .the contact is more reliable and the edges come closer with great effort. During the docking process, the strap 6, moving in front of the wheels 3 along the edges, protects the joined edges from undulating deformations by the front end, and its rear end serves as a cover protecting the buttress fingers from rotating wheels. At the end of the docking of the blanks 10 and AND, the device is transferred to the following blanks and the cycle is repeated.

Применение предлагаемого устройства при стыковке резинокордных изделий позвол ет повыспть надежность стыковки, качество стыка и улучшить внешний вид стыкового соединени .The use of the proposed device in joining rubber-cord products allows increasing the reliability of the joint, the quality of the joint and improving the appearance of the joint.
