Abstract

PURPOSE:To obtain a motor control device which will cause no problem to the control of the tensile force of a center unwinder by controlling the motor of a paper guide roll in accordance with a current reference. CONSTITUTION:The motor 9 of a paper guide roll 2 is controlled in its speed while being controlled in its current by the output of a current reference generating circuit 33 which generates the current reference of the driving motor 9 based on the outputted coil diameter of a coil-diameter operating circuit 34 and the speed of surface winders 5. The mechanical loss of the paper guide roll 2 is varied by the speed of the surface winders 5, while also varied due to the change in the contact angle between the paper guide roll 2 and a sheet of paper caused by the change in the coil diameter of a center unwinder 1. The sum of the loss to the speed of the surface winders 5 and the loss to the coil diameter of a winding roll 4 is the total loss and, to compensate this, the current value of the motor 9 is obtained.

Depending on the speed of the surface winder 5, the mechanical loss of the paper guide roll 2 changes as shown in FIG.
As the coil diameter of the center unwinder 1 changes, the contact angle of the paper guide roll 2 with the paper changes, and the mechanical loss changes as shown in FIG. 3. The sum of the loss due to the speed of the surface winder 5 and the loss due to the coil diameter of the take-up roll 4 is the total loss of the paper guide roll 2, and the current value of the motor 9 to compensate for this total loss is:
It is obtained as shown in Figure 4. The current reference generating circuit 33 generates a current value as shown in FIG. 2 and provides a signal to the current controller.
