Problems solved by technology

[0003] In the prior art, a transmission roller is usually set in the device to drive the operation of the securities, so that the transmission stability is poor because the transmission wheel drives the securities on the circular arc surface, especially in the detection device, the securities In the detection area, it is easy to flutter up and down and move left and right, and the detection gap is unstable, which affects the detection effect. At the same time, the effective contact area between the securities and the detection sensor is small, which is limited to the local section between the roller and the detection sensor. This makes detection more limited

Embodiment 1

[0026] This embodiment is a device for detecting the full face of the 05 version of RMB 100, including a mechanism and a detection device for transmitting the securities. The main part of the transmission mechanism is a main belt 1 covering the entire detection area of ​​the sensor. The main belt 1 has a width of 100mm and a length of 130mm. The main belt 1 is fixed on the left and right transmission wheels 2, and its linear speed is the paper feeding speed of the mechanism, and the maximum is 3 m / s. The detection gap between the main belt 1 and the detection device 6 is changed by adjusting the upper and lower positions of the adjustment wheel 4 (the width of the adjustment wheel 4 is 110mm) and compressing the main belt 1 . In this embodiment, the detection device 6 has an effective detection width of 95 mm and a length of 90 mm, which includes a magnetic feature detection device 7 and an optical feature detection device 10, and performs full-face scanning of securities with...

Embodiment 2

[0029] The conveying structure is the same as in Embodiment 1. The valued securities 5 of this embodiment are valued securities with number magnetism, safety thread magnetism and soft magnetic properties, and the detection device 6 includes a magnetic characteristic detection device 7, and the magnetic characteristic detection device 7 also includes figure 2 The magnetic sensor 8 and the magnetizing device 9 shown are used to scan the number magnetism, security thread magnetism and soft magnetic magnetism on the value document 5 in full. The main belt 1 covers the entire detection area, and the transmission mechanism ensures stable magnetization and stable detection of the magnetic material on the value certificate 5 by the detection device.

Embodiment 3

[0031] The conveying structure is the same as that in Embodiment 1. The valuable securities 5 of this embodiment have optical characteristics such as fluorescence and infrared. The detection device 6 includes an optical characteristic detection device 10, and the optical characteristic detection device 10 also includes image 3 The optical detector 11 and the light source 12 shown are used to scan the full face of the securities 5 on optical features such as fluorescence and infrared. The main belt 1 covers the entire detection area, and the transmission mechanism ensures that the detection device performs stable excitation and stable detection of the optical material on the value certificate 5 .

Abstract

A valuable papers feeding mechanism comprises a main belt and two drive wheels. The main belt is wound on the two drive wheels. Value papers are conveyed by friction with the main belt. The valuable papers feeding mechanism allows a whole plane of each of the valuable papers to serve as a next procedure object. Especially when applied to the field of detection, the valuable papers feeding mechanism ensures a stable detection clearance between the valuable papers and a detection sensor, vertical flapping and transverse playing of the valuable papers in a detection area are eliminated to the greatest extent, and magnetic features or optical features of the valuable papers are restored more accurately. In addition, detection sensors of corresponding sizes can be placed at any position on the coverage surface of the main belt, so that the effective detection area of a valuable papers processing device is enlarged.

Description

technical field [0001] The invention relates to the field of securities detection, in particular to a conveying mechanism and detection device for securities. Background technique [0002] For the processing device of securities, especially the detection device, it is necessary to set up a transmission mechanism in it, and the transmission mechanism drives the operation of the securities in order to complete a series of functions such as depositing, withdrawing, testing, and refunding. . [0003] In the prior art, a transmission roller is usually set in the device to drive the securities, so that the transmission stability is poor because the transmission wheel drives the securities on the arc surface of the circumference, especially in the detection device, the securities In the detection area, it is easy to flutter up and down and move left and right, and the detection gap is unstable, which affects the detection effect. At the same time, the effective contact area betwee...
