Title: Feed roll controller for process line
Inventor: SHINTAKU MOTOCHIKA
IPC: H02P29/00
Filed: 1988-03-10
Abstract: PURPOSE:To control the loop and the tensile force of a sheet in a reservoir stably by providing a match detector for detecting zero torque difference and switching from speed control to torque control. CONSTITUTION:When deceleration is made for the purpose of switching of winding, contact (a) is switched to switch an outside roll 3 from torque control to speed control while a contact C is opened to bring the speed reference for the outside roll 3 and a winding section to zero. Consequently, a speed difference occurs between a central roll 2 and the outside roll 3 to produce a loop of sheet in an outside reservoir 21. When the speed of the outside roll 3 is controlled and the loop is lifted to produce tensile force of sheet in the outside reservoir 21, actual torque reference outputted from a speed controller 8 contains the component of sheet tensile force thus bringing the difference between the actual torque reference and the torque reference provided from a torque reference setter 13 to zero. Consequently, a match detector 11 functions to switch the contact (a) to the side of torque control thus transiting smoothly to steady operation.
