Filed: 1988-06-22
Abstract: PURPOSE:To extend the control range of tension by conducting the energizing means of a dancer roller to the tension of wire rods by a motor, and realizing a virtual spring by said motor and the control program thereof. CONSTITUTION:A tension calculating part 8 is capable of detecting with satisfac tory accuracy even in a non-equilibrium by calculating the instantaneous value of tension from the speed signal 6 of a speed sensor 16 and the current signal 5 of a current sensor 15 of a virtual spring motor 4. When an arm 2 supporting a movable roller 1 is displaced 13 from a standard position 14 by the tension of a wire rod 19, a virtual spring calculating part 10 calculates the driving capacity required for a motor 4 to generate a restoring force proportional to the displacement 13 from the instantaneous value of the above tension and the position signal 7 of the motor 4, based on the preset virtual parameter of the virtual spring mechanism, and outputs it in the form of speed command value. As this parameter is realized by a value within the control program, the change of this parameter enables the motor 4 to follow the operation of an optional virtual spring mechanism widely.
