Description
(5) УСТРОЙСТВО ДЛЯ РЕГУЛИРОВАНИЯ ПЛОТНОСТИ НАМОТКИ ЛЕНТОЧНОГО МАТЕРИАЛА(5) DEVICE FOR REGULATING THE DENSITY OF WINDING OF BELT MATERIAL
Изобретение относитс к устройст вам дл регулировани плотности намотки ленточного материала и может быть использовано в любой отрасли народного хоз йства, где примен етс опр:раци намотки, например в химической , целлюлозно-бумажной или текстильной промышленности. Известно устройство дл регулировани плотности намотки ленточного материала, содержащее измеритель плотности намотки, соединенный через корректор с узлом прижима наматываемого рулона fl}. Однако сравнительно низка точность регулировани плотности намотки ленточного материала этим устройством св зана со значительным запаздыванием при регулировании пло ности намотки. Цель изобретени - повышение точ ности регулировани . Цель достигаетс тем, что в устройстве измеритель плотности намотки выполнен в виде двух импульсных тахометров , установленных на ос х наматываемого рулона и одного из несущих валов намоточного станка, а корректор содержит последовательно соединенные блок контрол радиуса намотки , блок пам ти текущего значени радиуса, блок ввода закона регулировани усили прижима, цифроаналоговый преобразователь и усилитель, причем выходы тахометров соединены с входами блока контрол радиуса намотки. На чертеже представлена блок-схема устройства. Устройство содержит измеритель плотности намотки, выполненный в виде двух импульсных тахометров 1 и 2, установленных на ос х наматывающего рулона 3 и одного из несущих валов Ц намоточного станка, коррекThe invention relates to devices for controlling the density of the winding of a tape material and can be used in any branch of the national economy where a winding arrangement is used, for example in the chemical, pulp and paper or textile industry. A device for controlling the density of the winding of a tape material is known, which comprises a winding density meter connected through an equalizer to a unit of pressure of the winding roll fl}. However, the accuracy of adjusting the density of the winding of a tape material by this device is relatively low due to the considerable delay in adjusting the winding density. The purpose of the invention is to improve the accuracy of regulation. The goal is achieved by the fact that in the device the winding density meter is made in the form of two pulse tachometers mounted on the axes of the winding roll and one of the supporting shafts of the winding machine, and the equalizer contains the winding radius control unit, the current value radius memory block, the input block clamping force control law, a digital-to-analog converter and an amplifier, with the outputs of the tachometers connected to the inputs of the winding radius control unit. The drawing shows the block diagram of the device. The device contains a winding density meter, made in the form of two pulse tachometers 1 and 2, mounted on the axis of the winding roll 3 and one of the carrier shafts of the winding machine, corrections
