Description
Блок формирования периодического профиля композитной арматуры Block for forming a periodic profile of composite reinforcement
Изобретение относится к области строительства, а именно к оборудованию для производства композитной арматуры, содержащей спиральную обмотку, которая применяется для армирования бетонных конструкций и изделий. The invention relates to the field of construction, namely to equipment for the production of composite reinforcement containing a spiral winding, which is used to reinforce concrete structures and products.
По патенту RU 2417889 известна технологическая линия для изготовления композитной арматуры, состоящая из двух блоков основного оборудования: блока подготовки и пропитки ровинга полимерным связующим, включающего шпулярник с бобинами ровинга, выравнивающее устройство, камеру отжига, пропиточную ванну, натяжное устройство, формующее устройство, и блока формирования структуры наружной поверхности арматуры, включающего два узла спиральной обмотки, полимеризационные камеры, ванну охлаждения, тянущее устройство, узел резки и сматывания, снабженная одним или несколькими дополнительными блоками оборудования выполнения спиральных обмоток внутренних слоев арматуры. According to patent RU 2417889, a technological line for the manufacture of composite reinforcement is known, consisting of two blocks of main equipment: a block for preparing and impregnating roving with a polymer binder, including a creel with roving spools, a leveling device, an annealing chamber, an impregnating bath, a tension device, a forming device, and a block forming the structure of the outer surface of the reinforcement, including two spiral winding units, polymerization chambers, a cooling bath, a pulling device, a cutting and winding unit, equipped with one or more additional units of equipment for performing spiral windings of the inner layers of the reinforcement.
Недостатком данной технологической линии является низкая производительность оборудования, связанная с перерывами в работе, вызванными необходимостью частой замены катушек предварительно скрученного ровинга в узлах спиральной обмотки. The disadvantage of this technological line is the low productivity of the equipment associated with interruptions in operation caused by the need for frequent replacement of coils of pre-twisted roving in the nodes of the spiral winding.
Известна линейка оборудования TECHPRO производства ООО НПО «ТехКом», представленная сериями: линия для производства стеклопластиковой арматуры ТР- 1 ОООи, линия для производства стеклопластиковой арматуры ТР-2000. A well-known line of equipment TECHPRO manufactured by LLC NPO TekhKom, represented by the following series: a line for the production of fiberglass reinforcement TR-1 LLCi, a line for the production of fiberglass reinforcement TR-2000.
Обе включают в себя блок формирования периодического профиля композитной арматуры, состоящий из каркаса, на котором установлена рама с двумя катушками, расположенными параллельно, соединенными с электроприводом. Скрутка происходит за счет привода вращения катушек вокруг своей оси, а намотка периодического профиля за счет вращения рамы, перемещающей катушки вокруг потока нитей несущего стержня арматуры. Both include a block for forming a periodic profile of composite reinforcement, consisting of a frame on which a frame is installed with two coils located in parallel, connected to an electric drive. Twisting occurs due to the drive of the rotation of the coils around its axis, and the winding of the periodic profile due to the rotation of the frame, which moves the coils around the flow of threads of the supporting rod of the reinforcement.
Известное устройство позволяет объединить устройство скрутки ровинга и устройство спиральной обмотки в один блок, однако недостатком известного устройства является необходимость использования в качестве средств спиральной обмотки потока нитей несущего стержня, специальных сменных катушек с внешним размотом либо, перед установкой на устройство, производить намотку ровинга на
вышеуказанные катушки со стандартных бобин с внутренним размотом при помощи отдельного устройства. Необходимость использования сменных катушек с внешним размотом снижает производительность оборудования, поскольку вышеуказанные сменные катушки имеют ограниченный размер, что связано с сильными колебаниями, возникающими при их вращении вокруг потока нитей несущего стержня арматуры. Таким образом, прерывать работу блока формирования периодического профиля для замены катушек необходимо чаще. The known device makes it possible to combine a roving twisting device and a spiral winding device into one unit, however, a disadvantage of the known device is the need to use carrier rod threads, special replaceable coils with external unwinding as means of spiral winding, or, before installation on the device, wind the roving on the above reels from standard reels with internal unwinding using a separate device. The need to use interchangeable externally unwound spools reduces the productivity of the equipment, since the above-mentioned replaceable spools are of limited size, due to the strong vibrations that occur when they rotate around the flow of threads of the supporting bar of the armature. Thus, it is necessary to interrupt the operation of the periodic profiling unit to replace the coils more frequently.
Наиболее близким к заявленному техническому решению является известная по патенту RU2534130 технологическая линия для изготовления композитной арматуры, включающая блок формирования периодического профиля композитной арматуры, состоящий из установленных на каркасе устройства скрутки нитей ровинга для формирования несущего стержня арматуры, двух параллельных катушек с нитью для спиральной обмотки несущего стержня арматуры, оборудованных электроприводами и выполненных с возможностью синхронного вращения вокруг своей оси, при этом над каждой из параллельных катушек расположено челночное устройство для спиральной обмотки несущего стержня арматуры. The closest to the claimed technical solution is the technological line for the manufacture of composite reinforcement known from patent RU2534130, which includes a block for forming a periodic profile of composite reinforcement, consisting of a device for twisting roving threads installed on the frame to form a supporting reinforcement rod, two parallel coils with a thread for spiral winding of the carrier rebar equipped with electric drives and made with the possibility of synchronous rotation around its axis, while above each of the parallel coils there is a shuttle device for spiral winding of the rebar.
Недостатком известного устройства является необходимость использования специальных сменных катушек с внешним размотом либо, перед установкой на устройство, необходимость производить намотку ровинга на вышеуказанные катушки со стандартных бобин с внутренним размотом при помощи отдельного устройства. Необходимость использования сменных катушек с внешним размотом, несмотря на то, что известное устройство обрабатывает два потока нитей несущего стержня арматуры, снижает производительность устройства, поскольку вышеуказанные сменные катушки имеют ограниченный размер, связанный с ограниченным объемом места для их размещения в каркасе устройства. Кроме того, сменные катушки небольшого диаметра с внешним размотом не являются стандартной формой выпуска ровинга, а специально производятся для использования на оборудовании для производства композитной арматуры, в связи с этим они выпускаются ограниченным числом производителей и имеют высокую стоимость. Применение же бобин ровинга стандартного формата с внутренним размотом на известном устройстве невозможно в связи технологическими ограничениями оборудования. A disadvantage of the known device is the need to use special interchangeable coils with external unwinding or, before installation on the device, the need to wind the roving on the above coils from standard bobbins with internal unwinding using a separate device. The need to use replaceable coils with external unwinding, despite the fact that the known device processes two threads of the threads of the supporting rod of the reinforcement, reduces the productivity of the device, since the above-mentioned replaceable coils have a limited size associated with a limited amount of space for their placement in the frame of the device. In addition, small-diameter, externally unwound replaceable spools are not a standard form of roving production, but are specifically manufactured for use on composite rebar manufacturing equipment, and therefore are produced by a limited number of manufacturers and are expensive. The use of roving bobbins of a standard format with internal unwinding on a known device is impossible due to technological limitations of the equipment.
Техническим результатом заявленного изобретения является повышение производительности устройства, обеспечение возможности заправки катушек с
бобины стандартного формата непосредственно в процессе работы без длительных технологических остановок в процессе производства. The technical result of the claimed invention is to increase the performance of the device, providing the possibility of filling coils with reels of a standard format directly in the course of work without long technological stops in the course of production.
Технический результат достигается тем, что в блоке формирования периодического профиля композитной арматуры, включающем каркас, катушки, электропривод, расположенное над каждой из катушек челночное устройство для спиральной обмотки потока нитей несущего стержня арматуры, согласно изобретения, в верхней части каркаса соосно друг с другом и соосно с потоком нитей несущего стержня арматуры расположены первая и вторая горизонтальные катушки с полыми сердечниками, каждая из которых имеет собственный отключаемый привод, в нижней части каркаса выполнен узел для размещения сменных вертикальных бобин ровинга под первой и второй горизонтальными катушками. The technical result is achieved by the fact that in the block for forming a periodic profile of composite reinforcement, including a frame, coils, an electric drive, a shuttle device located above each of the coils for spiral winding the flow of threads of the bearing rod of the reinforcement, according to the invention, in the upper part of the frame coaxially with each other and coaxially the first and second horizontal coils with hollow cores are located with the flow of threads of the supporting rod of the reinforcement, each of which has its own switchable drive, in the lower part of the frame there is a unit for placing replaceable vertical roving bobbins under the first and second horizontal coils.
Две горизонтальные катушки с полыми сердечниками, расположенные соосно с потоком нитей несущего стержня, и узел поочередного размещения вертикальной бобины ровинга под первой и второй горизонтальными катушками, позволяют обеспечить непрерывность работы заявленного блока, поскольку при запуске работает только один его узел, где нить перематывается с вертикальной бобины ровинга, находящейся под первой верхней катушкой, оснащенной собственным электроприводом, на вышеуказанную катушку, привод которой в этот момент подключен, при этом в процессе перематывания нить скручивается, а после разматывания нити с нижней вертикальной бобины ровинга она меняется на новую и размещается под второй верхней катушкой, повторяется тот же процесс, что и с первой верхней катушкой. При этом с целью формирования периодического профиля (ребра) в первом узле режим работы меняется и происходит наматывание перемотанной (скрученной) нити челноком с первой верхней катушки непосредственно на поток нитей несущего стержня арматуры, проходящий через соосные полые сердечники верхних катушек, при этом привод первой верхней катушки отключен, при полном разматывании нити с узла, работающего на формирования периодического профиля, происходит короткая остановка для переустановки нити с уже намотанной к тому времени резервной катушки. Во время работы устройства поток проходит сквозь сердечники горизонтальных катушек. Таким образом, оба узла работают попеременно, что обеспечивает фактическую непрерывность работы оборудования, а, следовательно, обеспечивает повышение производительности. Two horizontal coils with hollow cores, located coaxially with the flow of threads of the carrier rod, and a node for alternately placing a vertical roving bobbin under the first and second horizontal coils, ensure the continuity of the operation of the claimed unit, since only one of its nodes works at startup, where the thread is rewound from the vertical roving bobbin, located under the first upper bobbin, equipped with its own electric drive, to the above bobbin, the drive of which is connected at this moment, while in the process of rewinding the thread is twisted, and after unwinding the thread from the lower vertical roving bobbin, it changes to a new one and is placed under the second upper coil, the same process is repeated as with the first upper coil. At the same time, in order to form a periodic profile (rib) in the first node, the operating mode changes and the rewound (twisted) thread is wound by a shuttle from the first upper coil directly onto the thread flow of the armature carrier rod passing through the coaxial hollow cores of the upper coils, while the drive of the first upper spool is turned off, when the thread is completely unwound from the node working on the formation of a periodic profile, there is a short stop to reinstall the thread from the reserve spool already wound by that time. During operation of the device, the flow passes through the cores of the horizontal coils. Thus, both nodes work alternately, which ensures the actual continuity of the equipment, and, therefore, provides an increase in productivity.
Заявленное изобретение позволяет исключить использование сменных катушек, поскольку соосные катушки являются частью оборудования, и
использовать для заправки катушек непосредственно в процессе работы бобины ровинга стандартного формата (высотой 260 мм; диаметром 185 мм; массой 9-15 кг). The claimed invention makes it possible to eliminate the use of interchangeable coils, since coaxial coils are part of the equipment, and use standard format roving bobbin (height 260 mm; diameter 185 mm; weight 9-15 kg) for filling coils directly during operation.
Проведенные заявителем испытания опытного образца заявленного блока формирования периодического профиля композитной арматуры показали, что он обеспечивает непрерывную намотку ребра в течение 12 и более часов, так как в процессе производства режимы работы узлов блока поочередно меняются, в устройстве используются бобины ровинга стандартного формата (высотой 260 мм; диаметром! 85 мм; массой 9-15 кг, с размоткой по внутреннему диаметру), по причине расположения верхних катушек соосно с потоком нити несущего стержня; при работе устройства соблюдается угол нанесения ребра на ствол потока, близкий к прямому, что позволяет получить высокие характеристики по вырыву арматуры из бетона; шаг намотки ребра регулируется в переделах от 10 до 30 мм. Tests carried out by the applicant of a prototype of the claimed block for forming a periodic profile of composite reinforcement showed that it provides continuous winding of the rib for 12 hours or more, since during the production process the operating modes of the block units alternately change, the device uses roving reels of a standard format (260 mm high ; diameter! 85 mm; weight 9-15 kg, with unwinding along the inner diameter), due to the location of the upper coils coaxially with the flow of the thread of the carrier rod; during operation of the device, the angle of application of the rib to the flow shaft is close to direct, which makes it possible to obtain high characteristics for tearing out reinforcement from concrete; the step of winding the rib is adjustable in the range from 10 to 30 mm.
