Механизм подачи' карт от гильотинных ножниц 3 к дисковым 5 выполнен в виде (фиг.З) кареток 9 с толкателями 10, совершающих возвратно-поступательное перемещение в направляющих пазах 11 стола 12 и шарнирно закрепленных на концах параллельных рычагов основной П-образной скобы 13, основание которой шарнирно связано с концами дополнительной П-образной скобы 14, основание которой шарнирно закреплено в ста'нине 15. Основная П-образная скоба 13, несущая каретки 9 шарнирно связана с шатуном 16, противоположный конец которой проходит через фрикционную тормозную втулку 17, шарнирно закрепленную-на каретке 18 захвата 19 механизма подачи рулонного материала в гильотинные ножницы.The feed mechanism of the cards from the guillotine shears 3 to the disk 5 is made in the form (Fig. H) of the carriages 9 with pushers 10, reciprocating in the guide grooves 11 of the table 12 and pivotally mounted at the ends of the parallel levers of the main U-shaped bracket 13, the base of which is pivotally connected to the ends of the additional U-shaped bracket 14, the base of which is pivotally fixed in the stanina 15. The main U-shaped bracket 13, the bearing carriage 9 is pivotally connected to the connecting rod 16, the opposite end of which passes through the friction brake th sleeve 17 pivotally mounted on the carriage 18, the nip 19 of the feeder of the web material in the shears.

Механизм подачи рулонного материала к гильотинным ножницам содержит две каретки 18 и 20, каждая из которых снабжена клещевым захватом 19 и 21, установленные на параллельных направляющих с обоих сторон поло сы рулонного мг’.териала 6, и снабженные приводом встречного возвратнопоступательного перемещения в направлении подачи ленты.The feed material supply mechanism to the guillotine shears contains two carriages 18 and 20, each of which is equipped with a tongs 19 and 21, mounted on parallel guides on both sides of the strip of rolled mg. Material 6, and equipped with a counter-reciprocating drive in the direction of feed .

Механизм подачи карт к дисковым ножницам (фиг.З и 4) имеет две симметрично расположенные системы П-образных скоб 13 и 14 и 22 и 23 с разноудаленными параллельными рычагами, связанные шатунами 16 с фрикционными втулками 17, шарнирно укрепленными на каретках механизма подачи рулонного материала к гильотинным ножницам.The card feed mechanism to the disk scissors (Figs. 3 and 4) has two symmetrically arranged U-shaped staple systems 13 and 14 and 22 and 23 with differently spaced parallel levers connected by connecting rods 16 to the friction bushings 17 pivotally mounted on the carriages of the roll material feeding mechanism to the guillotine shears.

На каждом из концов параллельных рычагов основных П-образных скоб 13 и 22 имеется ролик 24 (фиг.5), опирающийся на направляющие 11 стола. На оси ролика шарнирно закреплена каретка 9 с толкателем 10, закрепленным к каретке при помощи пружинящей пластины 25 и снабженным скосом, выполненным со стороны, противоположной дисковым ножницам.At each end of the parallel levers of the main U-shaped staples 13 and 22 there is a roller 24 (figure 5), based on the guides 11 of the table. A carriage 9 is pivotally mounted on the roller axis with a pusher 10 fixed to the carriage by means of a spring plate 25 and provided with a bevel made from the side opposite to the disk shears.

Автоматическая линия совмещенного реза работает следующим образом.’ .От разматывающего устройства 1 полоса рулонного материала 6 подается по столу в гильотинные ножницы 3 двумя каретками 18 и 20 с захватами 19 и 21, расположенными на направляющих с обеих сторон’ стола. Каретка с захватами, совершая от привода согласованные параллельные возвратно-поступательные движения навстречу друг другу, поочередно подают полосу рулонного материала 6 в гильотинные ножницы 3, исключая холостой ход при подаче. При этом, шарнирно закрепленные на каретках 18 и 20 фрикционные (тормозные) втулки 17 силами трения приводят в возвратно-поступательное встречное движение проходящие сквозь них шатуны 16, которые имея шарнир-ные соединения с рычагами основных П-образных скоб 13 и 22, несущих каретки 9 с толкателями 10, поворачивают рычаги с толкателями навстречу друг другу влево и вправо до упоров. Возможность встречно-перекрестного движения основных П-образных скоб 13 и 22 обеспечивается различием расстояний между их параллельными рычагами, несущими каретки с толкателями. Дополнительные П-образные скобы 14 и 23, шарнирно закрепленные в станине 15, обеспечивают изменение высоты осей поворота основных П-образных скоб 13 и 22 при прямолинейном дви женин кареток 9 в направляющих пазах 11 стола 12 за счет перемещения по ним роликов 24, закрепленных по одному на концах рычагов основных П-образных. скоб 13 и 22 несущих толкатели 10, каретки которых шарнирно закреплены на осях роликов. Во время отрезки карты 7 гильотинными ножницами 3 каретки 18 и 20 с захватами и каретки 9 с толкателями 10 находятся в крайних (левом и правом) положениях. Отрезанная карта 7 падает на стол 12 между толкателями 10.The automatic line of combined cutting works as follows: ’. From the unwinder 1, a strip of roll material 6 is fed across the table to the guillotine shears 3 with two carriages 18 and 20 with grippers 19 and 21 located on the rails on both sides of the table. The carriage with grippers, making coordinated parallel reciprocating movements from the drive towards each other, alternately feeds a strip of web material 6 into the guillotine shears 3, excluding idling when feeding. At the same time, friction (brake) bushings 17 pivotally mounted on the carriages 18 and 20 cause friction forces to reciprocate through the connecting rods 16 passing through them, which are articulated with levers of the main U-shaped staples 13 and 22 carrying the carriages 9 with pushers 10, turn levers with pushers towards each other left and right to the stop. The possibility of counter-cross movement of the main U-shaped staples 13 and 22 is provided by the difference in the distances between their parallel levers carrying the carriages with pushers. Additional U-shaped brackets 14 and 23, pivotally mounted in the frame 15, provide a change in the height of the axis of rotation of the main U-shaped brackets 13 and 22 with a rectilinear movement of the carriages 9 in the guide grooves 11 of the table 12 due to the movement of the rollers 24 fixed along them one at the ends of the levers of the main U-shaped. brackets 13 and 22 of the bearing pushers 10, the carriages of which are pivotally mounted on the axes of the rollers. During segments of the card 7 guillotine shears 3 carriages 18 and 20 with grippers and carriages 9 with pushers 10 are in the extreme (left and right) positions. The cut-off card 7 falls onto the table 12 between the pushers 10.

При возобновлении встречного движения кареток 18 и 20 с захватами (захват, двигающийся к гильотинным ножницам, подает материал от рулона), шарнирно закрепленные на каретках (тормозные) фрикционные втулки 17 силами трения двигают шатуны 16, через которые приводят во встречное движение основные П-образные скобы 13 и 22, несущие толкатели. При этом любая пара толкателей П-образной скобы при движении от дисковых ножниц, за счет имеющегося у них скоса и крепления на пружинящих пластинах 25, утапливается картой в направляющие пазы стола, а при движении к дисковым ножницам обеспечивает захват карты по краям и разворот .ее кромок параллельно оси дисковых ножниц.When resuming the oncoming movement of the carriages 18 and 20 with grippers (the gripper moving to the guillotine shears feeds material from the roll), the friction bushings 17 pivotally mounted on the carriages (brake) move the connecting rods 16 through which the main U-shaped staples 13 and 22, bearing pushers. In this case, any pair of pushers of the U-shaped bracket when moving away from the disk scissors, due to the bevel they have and fastening on the spring plates 25, is recessed by the card into the guide grooves of the table, and when moving to the disk scissors, it ensures the card is grabbed at the edges and rotated. edges parallel to the axis of the disk shears.

Подача карты толкателями осуществляется со скоростью, большей чем окружная скорость дисковых ножниц (с некоторым подпором), что предотвращает перекос карты при первоочередном схватывании ее боковых мятых кромок дисковыми ножницами. После зажатия карты дисковыми ножницами скорость толкателей вынужденно уменьшается за счет перемещения шатуна в фрикционной (тормозной) втулке, обеспечивая работоспособность автоматической линии совмещенного реза.The card is supplied with pushers at a speed greater than the peripheral speed of the disk scissors (with some back pressure), which prevents the card from skewing when the lateral wrinkled edges are first grasped by the disk scissors. After clamping the card with disc scissors, the pusher speed is forced to decrease due to the movement of the connecting rod in the friction (brake) sleeve, ensuring the operability of the automatic line of the combined cut.

Использование изобретения позволяет согласовать скорость отдельных механизмов автоматической линии совмещенного реза и исключить их переналадку в случаях изменения длины отрезаемых карт или переточки ножей дисковых ножниц, обеспечить точность прямого угла в нарезаемых пластинах за счет обеспечения сохранности параллельности кромки карты оси дисковых ножниц во время захвата карты дисковыми ножницами и повышение производительности за счет исключения холостого хода составляющих механизмов .The use of the invention allows to coordinate the speed of individual mechanisms of the automatic line of the combined cut and to prevent their readjustment in cases of changing the length of the cut cards or regrinding knives of circular shears, to ensure the accuracy of the right angle in the cut plates due to the preservation of the parallelism of the edge of the card axis of the disk shears during card capture by disk shears and increased productivity by eliminating the idling of constituent mechanisms.
