摘要

A banknote temporary storage module and a reel rotating speed control method thereof. The banknote temporary storage module comprises a large reel (201) driven by a first power motor, a small reel (202) driven by a second power motor, a coiling tape (208), a first coded disc (203), a second coded disc (204), a first sensor (205), a second sensor (206) and a microcontroller. Two ends of the coiling tape are separately fixed on the large reel and the small reel and the coiling tape is retracted and wound between the large reel and the small reel. The first coded disc is fixed on a rotating shaft of the large reel. The second coded disc is fixed on a rotating shaft of the small reel. The first sensor is arranged corresponding to the first coded disc and is used for monitoring the rotating angle of the large reel. The second sensor is arranged corresponding to the second coded disc and is used for monitoring the rotating angle of the small reel. The microcontroller is used for calculating, according to output signals of the first sensor and the second sensor, the length of the coil tape released by the small reel each time the large reel rotates for one circle, and further calculating the current radius of the large reel, and thus angular velocities of the large reel and the small reel are controlled and the linear velocity of the large reel is enabled to be consistent with that of the small reel.
