一、铝箔的高速收卷用无级变速机A送出铝箔,以无级变速机B进行高速收卷时,光检测出调节辊的情况来实现无级变速机A、B之间的控制,有时不可能耐高速运行。这种情况下,用无接触可变压器预先将B辊的卷径测出。把这个检测出的电压和测速表A测定的电压进行运算以取作基准电压。这样,如果无级变速机B按照转速表B和基准电压的差值信号跟踪控制的话,检测上的时间延迟就不会出现,控制就成为可能了。然而,为了近似地变化无级变速机的转速,两辊之间的累计误差会在调节辊上表现出。
First, the high-speed winding of aluminum foil with a continuously variable transmission A sent to the CVT B high-speed winding, the light detection of the condition of the roller to achieve the CVT A, B between the control, and sometimes It is impossible to run at high speed. In this case, the coil diameter of the B roll is measured in advance using a contactless transformer. The detected voltage and the voltage measured by the tachometer A are calculated as a reference voltage. In this way, if the continuously variable transmission B follows the control of the difference signal of the tachometer B and the reference voltage, the detection of the time delay does not occur and the control becomes possible. However, in order to approximately change the speed of the CVT, a cumulative error between the two rollers is exhibited on the dancer roller.
