<P>PROBLEM TO BE SOLVED: To prevent facility costs and occupancy spaces from significantly increasing due to an increase in width of a belt-like sheet to be transported, and to drive a guide roller group that prevents the belt-like sheet from being scratched without using a complicated speed control system. <P>SOLUTION: A guide roller group R is divided into a first section guide roller group Ra driven by a transmission system Ta via a main motor M1 and a second section guide roller group Rb driven by an auxiliary motor M2 via a transmission system Tb, and is provided with a tuning transmission device 1 connecting the transmission system Ta with the transmission system Tb. The speed of the main motor M1 is controlled by the main motor control device 2. An auxiliary motor control device 3 that controls torque of the auxiliary motor M2 momentarily calculates the torque Tm2 of the auxiliary motor M2 based on both the relational expression expressed in the linear function, where the torque Tm1 of the main motor M1 is an independent variable and the torque Tm2 of the auxiliary motor M2 is a dependent variable, and the detected torque value of the main motor M1, and issues a command. <P>COPYRIGHT: (C)2012,JPO&INPIT |
