Bill thickness detecting device

Abstract

The present invention discloses a bill thickness detecting device arranged in an ATM banknote processing mechanism. The device comprises a conveying roller, an upper infrared distance measurement sensor, a lower infrared distance measurement sensor, and a controller. The conveying roller provides power to allow a bill to move along a bill transport path. The upper infrared distance measurement sensor and the lower infrared distance measurement sensor are symmetrically arranged at two sides of the bill transport path and are connected to the controller and transport distance data detected in real time to the controller. The controller is internally provided with a data collection module, a data analysis module, and a data processing module. The data collection module receives measurement data in real time. The data analysis module analyzes the measurement data. The data processing module receives the data information analyzed by the data analysis module and judges whether the bill is qualified or not. According to the technical scheme, comprehensive bill thickness data can be obtained, whether the bill is qualified or not can be comprehensively evaluated, the bill conveying speed can be raised, the detection efficiency is improved, and the detection effect is not affected.

Description

technical field [0001] The invention relates to paper thickness detection equipment, in particular to a banknote thickness detection device. Background technique [0002] In automatic teller machines (ATM) and automatic teller machines (CD), in order to determine the number of banknotes deposited or taken out and to determine whether the banknotes are qualified or not, it is usually necessary to detect the thickness of the banknotes. However, in the prior art, the main application is to realize the combination of the fixed reference roller and the movable press detection roller. By detecting the displacement and movable distance of the press detection roller, it is measured whether there is adhesive tape or folded corners or multiple corners on the surface of the banknote. In this way, it is judged whether the banknote is a qualified currency or a rejected currency and decides whether to continue the transaction. [0003] However, the following problems are becoming increas...

AI Technical Summary

Problems solved by technology

[0005] 2. The way of using the detection roller is easy to cause the fatigue of the detection roller due to repeated high-frequency use, thereby reducing the detection accuracy;

[0006] 3. Since the contact detection method requires sufficient response time, otherwise there will be a blank stage when the detection roller moves up and down, and it is difficult to speed up the detection speed of the banknotes

[0009] This technical solution can realize the detection of the thickness of the banknote, and then determine whether the banknote is qualified or not, but it is obviously difficult to overcome the problems in the above-mentioned prior art by using the detection roller. Roller method to detect the thickness of banknotes, and can obtain comprehensive banknote thickness data, and comprehensively judge whether the banknote is qualified
