Abstract

The present invention relates to a laser detecting device for distinguishing counterfeit bank notes or tickets with anti-counterfeiting labels in a frequency spectrum and resonance mode, which comprises a general support frame, a detecting device arranged on the support frame, an automatic control system and a ticket transmission mechanism, wherein the detecting device is composed of one or more laser sensors, each laser sensor is divided into a laser transmitting sensor and a laser receiving sensor which are arranged at the upper side and the lower side of an input ticket. Because the principle that the spectral sensitivities of true-false tickets are different is used for discrimination, the present invention has the advantages of high detection sensitivity, low error detection rate, stable performance, high universality, etc. The present invention is combined with a currency count machine and has the advantages of easy loading and use, and convenient operation.

Description

Laser detector on the bill transfer line

The present invention relates to a kind of ticket pick-up unit, particularly adopt frequency spectrum, resonance manner identification counterfeit money or have the ticket pick-up unit of anti-fake mark.

Existing most of counting mechanism adopts the purple light diffraction to detect and distinguishes counterfeit money, and the minority product is also with simple hand magnetic ink pick-up unit, but all there is the shortcoming that discrimination is reliable inadequately, automaticity is low in they.On March 18th, 1998 Decree of Patent Office of China notification number be that CN2276647Y, name are called the patent of " purple light, magnetic detection, infrared penetrate triple fake-identifying bank-note counting machines ", it is by the circuit of purple light detection, magnetic detection and infrared detection, counterfeit money is carried out three re-detections, have multiple functional, distinguish the rate advantages of higher, but for no fluorescent effect, a little less than the counterfeit money resolving ability of the printing ink that is magnetic, the rate of false alarm height, can't detect the 5th cover Renminbi, thereby not reach user's requirement.

The present invention's purpose is to provide a kind of rate height of distinguishing, highly versatile, and especially the counterfeit money to the 5th cover Renminbi has uniqueness to distinguish laser detector on the bill transfer line of rate.

Technical scheme of the present invention is such: it comprises the versatility fixed support, is contained in pick-up unit, automatic control system and transporting ticket mechanism on the support.Pick-up unit is made of one or more groups laser sensor; Every group of laser sensor is divided into Laser emission sensor and laser pick-off sensor, and places the upper and lower both sides of input ticket.

Automatic control system of the present invention also can be provided with the sensing probe of control laser sensor automatic open close except that the program circuit system that is provided with formations such as filter inspection circuit, amplifying circuit.

The present invention for make ticket accurate, smooth, steadily enter pick-up unit, transporting ticket mechanism is made of the transporting rotor wheel or the pressing plate that are contained in the sliding ticket guide plate on the support and have an elastic mechanism.

Principle of work of the present invention is such: when ticket when transporting ticket mechanism enters between Laser emission sensor and the laser pick-off sensor, utilize the true and false ticket principle different to this spectral response; The laser pick-off sensor picks up signal, and the filter inspection circuit in automatic control system, amplifying circuit etc. produce electric signal; This signal enters microcomputer control system, can make it motor stall, buzzer warning etc. on the transmission line that this device is connected, thus the purpose of the ticket of realizing accurately telling truth from falsehood.

The present invention is owing to adopt laser sensor that ticket is distinguished, so have detection sensitivity height, low, the steady performance of false drop rate, its whole device independently is integral, not only can place on the corresponding position of paper money counter, and can be according to desired position in the ticket transmission system, install separately, have and easily adorn advantages such as easy-to-use, easy to operate.

Below in conjunction with embodiment shown in the drawings, the present invention is further detailed explanation.

Laser detector on the bill transfer line is by support 1, and the pick-up unit, automatic control system and the transporting ticket mechanism that are contained on the support 1 form.

Pick-up unit is made up of two groups of laser sensors 3, and is symmetrically distributed in transporting ticket mechanism center line both sides; Every group of laser sensor 3 is made up of Laser emission sensor 3b and laser pick-off sensor 3a, and divides the upper and lower both sides that are located at detected ticket, referring to Fig. 1, Fig. 3.Two groups of laser sensors 3 from the distance between center line of bill transmitting device 10 between 0-70mm, the position of visual ticket anti-fake mark is adjusted, as the 5th cover Renminbi, the position of two groups of laser sensor 3 decentering lines is best between 0-45mm, to guarantee that the pros and cons ticket can both be detected by laser sensor 3 time.Automatic control system comprises program circuit system 2 and the sensing probe 4 that is made of filter inspection circuit, amplifying circuit etc.; Sensing probe 4 is divided into four groups of two rows, and every row's sensing probe 4 has two pairs, divides the input port and the delivery outlet that are located at transporting ticket mechanism, sees Fig. 1, Fig. 4.The startup of the sensing probe 4 control laser sensors 3 of input port, when ticket entered transporting ticket mechanism, two sensing probes 4 recorded signal, made that by program circuit system 2 laser sensor 3 conductings are luminous again; 4 of the sensing probes of delivery outlet open circuit laser sensor 3 and close.The sensing probe 4 of automaton also can be installed in the optional position on the bill transfer line, opens and closes purpose as long as can reach control laser sensor 3, and its number of locations is determined on a case-by-case basis.

Transporting ticket mechanism is made of elastic transporting rotor wheel 5 of one or more alignings and sliding ticket guide plate 6, also can be made of single spring bearer plate 12, as Fig. 5; It not only make ticket can be smooth, exactly ground is by pick-up unit, and for the ticket of different thickness, can regulate the gap of input port automatically, and oppresses by elasticity, and ticket is close on the base plate of support 1 in testing process from start to finish.

The present invention can place in the dissimilar paper money counter 7 on the optional position on the banknote transmission lines, can twist with the fingers between paper money wheel 9 and the money out wheel 8 at horizontal or vertical paper money counter 7, and as Fig. 6, Fig. 8; Also can twist with the fingers paper money and take turns before 9 at horizontal or vertical paper money counter 7, or after the money out wheel 8, as Fig. 7, Fig. 9.Can also install separately in addition according to the needs in the ticket transmittance process.

In order to detect the printing ink magnetic of ticket, the present invention can also be equipped with magnetic sensor 11 in the center of frame bottom, and the quantity and the position of magnetic sensor 11 depend on the needs.

Support 1 height of the embodiment of the invention is 70mm, and wide is 25mm, and the ticket length that allows to enter detection is fit to detect Renminbi or other paper representing value of various version between 110-180mm.
