При совпадении оси ролика 44 с продольной осью рычага 52 ролик 44 сходит с направляющей 46 и поворачивает рычаг 52 вокруг оси шарнирного соединения. В это время ось 38 перемегцаетWhen the axis of the roller 44 coincides with the longitudinal axis of the lever 52, the roller 44 comes off the guide 46 and rotates the lever 52 around the axis of the hinge joint. At this time, axis 38 flashes

882684 6 ся по направляющей 46 прямолинейно . Затем рычаг 52 поворачивается по часовой стрелке, ось 42 вместе с кареткой 37 (ползушкой) опускается вниз, 5 а ролик 45 сходит с направляющей 47.882684 6 along the guide 46 in a straight line. Then, the lever 52 rotates clockwise, the axis 42 together with the carriage 37 (crawler) lowers down, 5 and the roller 45 comes off the guide 47.

При перемещении каретки 37 вправо рычаг 52 под действием пружины 54 вращается против часовой стрелки, ролик 44 выходит из паза а и начинает перемещаться по направляющей 46.Каретка 37' перемещается вверх.When the carriage 37 is moved to the right, the lever 52 rotates counterclockwise under the action of the spring 54, the roller 44 exits the groove a and begins to move along the guide 46. The carriage 37 'moves up.

При входе ролика 45 в паз δ опускание каретки 37 (ползушки)осуществляется аналогично.When the roller 45 enters the groove δ, the lowering of the carriage 37 (crawler) is carried out similarly.

Прямолинейные участки направляющих 46 и 47 ролики 44 и 45 проходят совместно и одновременно.The straight sections of the guides 46 and 47 of the rollers 44 and 45 pass together and simultaneously.

При нахождении траверсы 54 в крайнем правом положении захватные органы 61 захватывают верхний лист 12 стопы.When the traverse 54 is in the extreme right position, the gripping organs 61 grab the upper sheet 12 of the foot.

При перемещении траверсы 54 влево осуществляется перенос листа 12 с позиции на позицию.When moving the beam 54 to the left, the sheet 12 is transferred from position to position.

Загрузка стопы листов 12 на подъемный стол I 1 осуществляется с тележки 14.Loading a stack of sheets 12 on the lifting table I 1 is carried out from the trolley 14.

Предлагаемое устройство надежно в работе и обеспечивает возможность регулировки длины хода каретки.The proposed device is reliable in operation and provides the ability to adjust the stroke length of the carriage.
