Problems solved by technology

[0003] However, in general, a device that scans while conveying a medium has a problem in that the conveying speed of the medium fluctuates due to various factors such as mechanical factors of the device, thereby reducing the scanning accuracy.
In particular, in the above-mentioned sheet identification device, there is a problem that the conveying speed fluctuates due to the state of the sheet as the medium (the weight of the sheet, the degree of fatigue, etc.), thereby reducing the reading accuracy and the recognition accuracy of the sheet. reduce
[0005] This patent can adjust the conveying speed of banknotes and the cycle and time length of light irradiation to improve the recognition accuracy, but it still cannot recognize the banknote feature information without offset irradiation and projection, and cannot obtain banknote feature information with high reading accuracy

Embodiment 1

[0047] refer to figure 1, is a schematic diagram of the structure of the banknote type identification device of the present invention; combined figure 2 , is another schematic diagram of the structure of the banknote type identification device of the present invention. In the figure, a is the optical path generated by the light emitting unit 22, b is the banknote, c is the projection plate, E is the banknote transport path, and F is the projection plate transport path. As shown in the figure, the category identification device includes a control system 1, a lighting system, a banknote conveying system, and a projection system. in,

[0048] The banknote conveying system includes a first conveying roller 4 , a first conveying roller driving part 6 , and a first conveying roller speed detecting part 8 . The first conveying roller driver 6 is electrically connected to the control system 1 , and receives the first driving information transmitted by the control system 1 to contr...

Embodiment 2

[0059] combine Figure 4 , which is a flow chart of the identification method of the banknote category identification device of the present invention, it can be seen that the identification method of the above-mentioned banknote category identification device includes the steps:

[0060] Step a, conveying the banknote b along the banknote conveying path E;

[0061] Step b, the light emitting unit 2 illuminates the banknote b, and the projection board c moves along the projection board conveying path F;

[0062] Step c, the first conveying roller speed detector 8 detects the first conveying speed of the banknote conveying path E;

[0063] Step d, the control system 1 controls the second conveying roller drive unit 7 to adjust the second conveying speed of the projection plate conveying path F to be the same as the first conveying speed;

[0064] Step e, the projection board c receives the banknote feature value information projected on the projection board c when the banknote...

Abstract

The invention discloses a device for identifying categories of paper currency. The device for identifying categories of paper currency comprises a control system, a luminescent system, a paper currency conveying system and a projection system, wherein the paper currency conveying system conveys paper currency, and detects the paper currency conveying speed and adjusts the paper currency conveying speed; the luminescent system irradiates the paper currency continuously; the projection system comprises a second conveying roller, a driving part of the second conveying roller, a speed detection unit for the second conveying roller, an output conversion unit and a projection plate, and can control the conveying speed of the projection plate; a projection plate conveying path is arranged above the paper currency conveying path and can detect the projection plate conveying speed; the projection plate and the paper currency can be moved and conveyed synchronously; the paper currency characteristic quantity information generated from the paper currency is reflected and projected to the projection plate; and the control system receives the data transmitted from each unit and sends a control command. The invention also discloses an identification method for the device for identifying categories of paper currency. The device for identifying categories of paper currency, and an identification method thereof have the advantages of being simple in structure, being convenient to use, being able to project the paper currency characteristic quantity information to the projection plate without offset, and having excellent identification precision.

Description

technical field [0001] The invention relates to the field of equipment for identifying types of banknotes, in particular to a banknote type identifying device and an identifying method thereof. Background technique [0002] As a paper sheet identification device, the banknote identification device which identifies the denomination of a banknote is known. In the banknote identification device, usually while continuously conveying a plurality of banknotes, the printed pattern on the surface of the banknote is read by an optical element, and the currency type is identified using the read data. [0003] However, in general, a device that scans while conveying a medium has a problem in that the conveying speed of the medium fluctuates due to various factors such as mechanical factors of the device, thereby reducing the scanning accuracy. In particular, in the above-mentioned sheet identification device, there is a problem that the conveying speed fluctuates due to the state of t...
