Banknote Temporary Storage Module, Reel Speed ​​Control Method and Automatic Teller Machine

Abstract

The present application discloses a banknote temporary storage module, a reel speed control method, and an automatic teller machine. The method calculates the large reel and small reel by detecting the number of identification information on the tape per unit time. linear velocity, and then calculate the first angular velocity and the second angular velocity according to the desired linear velocity and the PID algorithm, respectively control the first power motor corresponding to the large reel and the second angular velocity according to the first angular velocity and the second angular velocity The second power motor corresponding to the small reel, it can be seen that in the technical solutions provided by the above-mentioned embodiments of the present application, the linear speed of the large and small reels is not affected by the thickness of the tape, the thickness of the banknotes and the radius of the reel, so Accurate linear speeds of large and small reels can be obtained, so the linear speeds of the large and small reels can be kept constant.

Description

technical field [0001] The present application relates to the technical field of banknote storage equipment, and more specifically, to a banknote temporary storage module and a method for controlling the rotational speed of a reel. Background technique [0002] The automatic cash recycling machine is equipped with a temporary storage module, which temporarily stores banknotes during the transaction process. At present, most commonly used temporary storage modules use a reel / tape mechanism, including: the first power motor, the second power motor, the large reel driven by the first power motor, the small reel driven by the second power motor and two The ends are respectively fixed on the large reel and the small reel, the winding tape is retracted between the large and small reels, and the microcontroller that controls the start or stop of the first power motor and the second power motor. This temporary storage module realizes the temporary storage of banknotes by using the ...

Problems solved by technology

Wherein the small reel rotates once, and its radius increase is constant, which is equal to the thickness of the tape. Due to the different thicknesses of the tapes of different specifications, the temporary storage module has poor adaptability to tapes of different thicknesses.

When the large reel rotates once, the increase in radius △X is equal to the thickness of the tape plus the thickness of the banknote. Because the distance between the banknotes is different and the thickness of different banknotes is different, it is impossible to accurately calculate △X, that is, the banknotes cannot be calculated accurately. Turning radius after entering the large reel

As a result, the linear speeds of the small and large drums obtained are not accurate enough, further resulting in large errors in the angular velocities of the first and second power motors, which cannot guarantee the constant linear speed of the large and small drums, resulting in The linear speed of the large reel and the small reel is different. When the deviation is relatively large, it is easy to cause tape throwing, or the load of the motor becomes larger, which will damage the hardware circuit, cause a shutdown due to failure, and increase manual maintenance.
