Description

The paper money counter pick-up unit

The utility model relates to the pick-up unit that adopts frequency spectrum, resonance manner identification counterfeit money, bill, securities on a kind of pick-up unit, particularly paper money counter.

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 they all exist and distinguish pseudo-reliable inadequately, shortcoming that automaticity is low.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, maybe can't debate not, thereby not reach user's requirement.

The purpose of the utility model is to provide a kind of not rate height of debating, highly versatile, and especially the counterfeit money to the 5th cover Renminbi has the paper money counter frequency spectrum resonance pick-up unit of distinguishing rate more by force.

The technical solution of the utility model is such: it comprises the support that is packed on the paper money counter, is contained in the testing agency on the support, the sequence circuit plate that is connected with pick-up unit.Testing agency is made of the laser sensor that a group or more is distributed in ticket input media center line one or both sides; Every group of laser sensor is divided into Laser emission sensor and laser pick-off sensor, and places the same side of banknote.

The utility model places between the sth. made by twisting paper money wheel of coin counting machine and the money out wheel or at the money out wheel front end, or after twisting with the fingers the paper money wheel.When ticket was put into banknote calculating table, the paper money counter entry into service made laser detector be in standby testing state, and when ticket entered laser detector, laser detector was started working.Its principle of work is such: when banknote enters between the emission sensor of laser and the laser pick-off sensor, utilize genuine notes and the counterfeit money principle different to spectral response, the laser pick-off probe, pick up reflection or penetrate or reflect and the different spectrum that penetrate intersection, filter inspection circuit on the via line plate, amplifying circuit produce pulse signal; This signal enters microcomputer control circuit, can make defeated paper money motor anxious stop stall, buzzer warning etc. on the paper money counter, thereby realizes accurately distinguishing the purpose of counterfeit money.

For stability, the susceptibility that improves laser spectrum, the utility model is equipped with one group of infrared emission tube and dash receiver parts on support, provides a pulse signal to microcomputer control circuit, to strengthen the resolution of laser detection system to the ticket true and false.

The utility model is owing to adopt laser sensor ticket to be distinguished so have detection sensitivity height, low, the steady performance of false drop rate, its whole device independently is integral, separately detection or with various paper money counter coupled in series, easily adorn easy-to-use, easy to operate.

Below in conjunction with embodiment shown in the drawings the utility model is done further detailed explanation.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is the A-A cut-open view of Fig. 1.

Fig. 4 is that the many groups of the utility model are paid the optical sensor structural representation.

Fig. 5 is that the utility model places the structural representation between horizontal type cash counter sth. made by twisting paper money wheel and the money out wheel.

Fig. 6 is the structural representation that the utility model places vertical paper money counter money out wheel front end.

Fig. 7 is that the utility model places vertical paper money counter to twist with the fingers the structural representation of holding after the paper money wheel.

Referring to Fig. 1, Fig. 2, Fig. 3, the paper money counter pick-up unit is by support 12, and the sequence circuit plate 8 that is contained on the support 12 is formed with the testing agency that is connected with circuit board 8.

Support 12 constitutes one by upper cartridge body 2a, lower box body 2b by web joint 1 and connection cover 11.On the support 12 upper cartridge body 2a cover plate 9, lead plate 10 are housed; One gap 7 of flowing for ticket is arranged between the upper and lower box body 2, light barrier 14 is housed on 7 mouthfuls in the gap; Support 12 is built-in with radiating module 5, infrared emission tube 3 and infrared ray dash receiver 4, is embedded with one group of laser sensor 6 of being made up of Laser emission sensor 3a and laser pick-off sensor 3b in radiating module 5, as testing agency.Laser emission sensor 3a and laser pick-off sensor 3b are positioned on the position of incident that same radiating module 5 relative gaps 7 planes are constituted and reflected ray, and form symmetry.

Infrared emission tube 3 and infrared ray dash receiver 4 are positioned at the same side of this group laser sensor 6.

, can both be detected by laser sensor 6 when the gap 7 in order to ensure positive and negative banknote, the utility model is loaded onto same one group of Laser emission sensor 6a and laser pick-off sensor 6b and infrared emission tube 3 and dash receiver 4 in lower box body 2a, referring to Fig. 5.Like this, the spectrum that laser pick-off sensor 6b can receive reflection simultaneously, penetrate, thus improved the rate of distinguishing to forged bill.Laser sensor 6 can also have many groups, and is distributed in support 12 center line both sides symmetrically.

The utility model can also be installed magnetic sensor 13 in support 12, to widen the anti-pseudo-range that detects all kinds of ticket volumes.

Referring to Fig. 5, Fig. 6, Fig. 7, the utility model can be contained on various types of paper money counters 15, as vertical paper money counter, horizontal type cash counter or desk-top static inspection paper money machine; And the position of being installed can be money out wheel 16 front ends, also can be between the rear end of twisting with the fingers paper money wheel 17 or sth. made by twisting paper money wheel 17 and money out wheel 16.
