Problems solved by technology

However, since the securities are not fully controlled while they are in this unobstructed detection area, this transport method has the risk of unstable transport and paper jams
However, in the prior art, there has not been a device and method that can stably hold securities and printed matter and can realize full-frame non-blind detection of transmission features.

[0040] see figure 2 with image 3 , at the first detection station, the line light source is arranged on the upper side of the securities, and illuminates downward from the upper surface of the paper of the securities, and the line scan camera is arranged on the lower side of the securities for collecting transmission images. At the second detection station, the line light source is arranged on the lower side of the securities to illuminate upwards from the lower surface of the paper of the securities, and the line array camera is arranged on the upper side of the securities to collect transmission images. In this embodiment, the line light sources of the two detection stations are respectively arranged on both sides of the valuable document, and illuminate from the two surfaces of the valuable document respectively.

[0041] combine figure 2 with image 3 It can be seen that in the first detection station and the second detection station, the pressing belt is pressed fro...

[0044] Such as Figure 4 As shown, in the first detection station and the second detection station, the line light source is arranged on the upper side of the securities, and illuminates downward from the upper surface of the paper of the securities, and the line scan camera is arranged on the upper side of the securities. Lower side, for acquisition of transmission images. In this embodiment, the line light sources of the two detection stations are arranged on the same side of the valuable securities, and the irradiating light is from the same surface of the valuable securities ( Figure 4 in the upper surface) incidence.

[0045] In this embodiment, in the first detection station and the second detection station, the pressing belt is pressed from one side of the negotiable securities, and the other side is provided with a supporting plate with hollow slits, and the hollow slits can be Add a glass sheet, the size of the hollow slit corresponds to the collection area of ​​se...

[0049] In the above two embodiments, in order to maintain the stable conveyance of the securities and at the same time ensure the stable acquisition of the transmission features, supporting plates and pressing belts are respectively arranged on both sides of the securities, and the supporting plates are arranged on the sides of the securities. At the junction of two belts on one side, the pressing belt drives the securities to move forward through friction; there are slits perpendicular to the movement direction of the securities on the supporting plate for light transmission.

[0050] In the third embodiment, double belts are used to transport valuable securities, that is, at the first detection station and the second detection station, pressing belts are provided on the upper and lower sides of the transmission channel, and the upper and lower sets of pressing belts The setting is under pressure on marketable securities. The difference between the first detection station and...

Abstract

The invention provides a detection device and method used for full-width discrimination of negotiable securities. In the detection device, two detection stations are arranged on a delivery channel, each detection station is provided with a set of hold-down belts, in the two detection stations, the positions where the negotiable securities are held down by the hold-down belts are different, and thus the positions where acquisition signals of the negotiable securities are shielded by the hold-down belts of the two stations are different; by comprehensively analyzing the transmission characteristics acquired by the two detection stations respectively, the full-width non-blind-area detection results of the negotiable securities are obtained. Through the dual-station detection method, the negotiable securities are held down on at least one side on the detection stations, the paper delivery stability is guaranteed, meanwhile, full-width non-blind-area detection of the negotiable securities is achieved, and the detection device and method are suitable for detecting the transmission characteristics of the negotiable securities.

Description

technical field [0001] The invention relates to a detection device for counterfeit detection of the whole width of the negotiable securities and a detection method for the full width detection of the negotiable securities, belonging to the technical field of financial identification. Background technique [0002] With the continuous development of negotiable securities processing and negotiable securities printing technology, the inspection requirements for the quality of paper and printed matter of negotiable securities are gradually increasing. [0003] In the existing negotiable securities detection device, the commonly used paper conveying method is: the upper and lower flat belts press the paper on both sides, and the paper and printed matter are conveyed between the two pressing surfaces; The characteristics of paper are therefore widely used. In this kind of conveying mode, a single-side belt is usually used to convey the full-width slit of the pallet on the other si...
