Note transportation and detection apparatus

Abstract

A paper currency transmitting and detecting device in the paper currency anti-forgery technology field includes: a guidance wheel set, a first money transmitting sliding plate, a first image sensor, a second money transmitting sliding plate, a second image sensor and a control module, wherein, the first money transmitting sliding plate is fixedly arranged at the front end of the second money transmitting sliding plate, the first image sensor is arranged below the first money transmitting sliding plate, the second image sensor is arranged above the second money transmitting sliding plate, the guidance wheel set is arranged between the first money transmitting sliding plate and the second money transmitting plate, and the control module is respectively connected with the guidance wheel set, the first image sensor and the second image sensor. The paper currency transmitting and detecting device controls twice anti-forgery detection by a controller program, and effectively leads the paper currency waiting to be detected to enter the detection area of the image sensors smoothly by the match of money transmitting sliding plates with specific shapes, thus ensuring image processing effect and reducing the generation of misjudgment.

Description

technical field [0001] The invention relates to a device in the technical field of banknote anti-counterfeiting, in particular to a banknote transport detection device. Background technique [0002] Paper money counting machines are widely used in banks and other money counting places. The banknote counter can not only save manpower, but also verify the authenticity of banknotes. In order to recognize the image of banknotes, CIS image sensors are usually used in the industry, and the banknotes are driven to pass through the CIS image sensor quickly by the rotation of the pressure roller. The rotation of the pressure roller needs to be driven by a motor and a drive plate. The structure is complex, the manufacturing cost is high, and assembly and maintenance are difficult. Moreover, the gap between the banknote and the CIS is required to be high, and it is easy to cause banknote jams during the transmission process. [0003] After searching the prior art, it is found that th...

Problems solved by technology

Since the longitudinal section of the transition section in the detection channel is arc-shaped, and the central angle α≥90°, the banknotes are smooth and stable, but this technology still exists for banknotes with surface wrinkles or small-angle tilting. Paper jams and false detection defects caused by the transition section of the technology; and the banknote input section of this technology does not involve image processing, making the distance between the banknote and the image processor inconsistent, which is not conducive to correctly judging the authenticity of the banknote
