Title:
ROLLER CONVEYOR DEVICE
Document Type and Number:
Japanese Patent JP2023110202
Kind Code:
A
Abstract:
To provide a roller conveyor device capable of improving controllability for the conveyance speed of an object to be conveyed.SOLUTION: Based upon a deviation of the rotating speed of a rotary disk 52 detected by a rotating speed detection part 53 from a target rotating speed of a brake roller 4 set with an adjusting knob 54, Ratio for finding a controlled variable of PWM control for determining regenerative resistance of a motor 51 is computed, and the Ratio is used to perform regenerative control to make the regenerative resistance that the motor 51 generates larger as the Ratio is larger. Consequently, the rotating speed of the brake roller 4 can be approximated to the target rotating speed, and controllability for the conveying speed of an object to be conveyed can be therefore improved.SELECTED DRAWING: Figure 2
