Abstract
The utility model relates to a banknote thickness detection apparatus, comprising a main framework, a swing shaft, a plurality of detection wheel devices, a detection driving shaft, and spring strips and Hall sensors with quantity identical to the quantity of the detection wheel devices, and a spring press strip. Each detection wheel device comprises a detection wheel framework, a driven wheel, and magnetic steel. One end of each spring strip is clamped between the main framework and the spring press stripe, and the other end of the spring strip is pressed on the detection wheel framework so as to apply force to the driven wheel and drive the driven wheel always to press against the detection driving shaft. All the Hall sensors face the magnetic steel and correspond with the magnetic steel in one-to-one correspondence. The plurality of detection wheel devices fluctuate in different degrees because of different thicknesses of the banknote, so that the Hall sensors can accurately determine thickness of each banknote by sensing fluctuation of the magnetic field from the corresponding magnetic steel. The banknote thickness detection apparatus is reasonable in structure, and can improve the rate of success by detecting thicknesses in different areas on the banknote.

Described detection wheel apparatus includes an end and swings the detection wheel carrier be enclosed within on axis of swing, is rotatably connected on the engaged wheel that detects wheel carrier other end bottom and is arranged on and detect the lip-deep magnet steel of wheel carrier;
Described spring leaf one end is clipped between main frame and band spring, and the other end is pressed in to detect on wheel carrier and makes the stressed detection main drive shaft that presses to all the time of engaged wheel;
All Hall elements are arranged on pcb board and towards magnet steel, and corresponding one by one with magnet steel;
Have the through hole in magnetic field that is used for sensing that magnet steel of its correspondence for Hall element on described spring leaf.
In the improvement project to above-mentioned paper money thickness testing apparatus, described detection wheel apparatus also includes to be arranged on and detects wheel carrier other end top and be used for clear dirt sheet to the clear dirt of wheel face of engaged wheel.
In the improvement project to above-mentioned paper money thickness testing apparatus, be provided with the limiting section that can keep off on the boss of main frame inwall in described clear dirt sheet upper end.
In the improvement project to above-mentioned paper money thickness testing apparatus, all spring leafs are connected by their clamping section.
In the improvement project to above-mentioned paper money thickness testing apparatus, each engaged wheel that detects wheel apparatus has two, and the central shaft of these two engaged wheels connects by the arm that is clipped between them.
compared with prior art, the beneficial effects of the utility model are: it is to utilize that a plurality of independently to detect wheel apparatus different and up do to make after in various degree fluctuation magnetic field on magnet steel also can do in various degree fluctuation along with the banknote thickness of correspondence position thereupon, thereby make with magnet steel one to one Hall element judge exactly the thickness of each section bank note by sensing magnetic fluctuation degree on corresponding magnet steel, come more accurately to measure the thickness of bank note, differentiate more accurately the true and false of bank note with this, so more reasonable structure of the present utility model, improve the pseudo-success ratio of banknote inspection by the thickness that more accurately detects the bank note zones of different.
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:

[embodiment]
The utility model is a kind of paper money thickness testing apparatus, as scheme its include main frame 4, be fixed on axis of swing 3 on main frame 4, be sleeved on a plurality of detection wheel apparatus 1 on axis of swing 3, with the tangent strip of the engaged wheel 11 that all detects wheel apparatus 1 detect main drive shaft 8, with the spring leaf 5 and Hall element 6 and the band spring 7 that detect wheel apparatus 1 equal amount
Described detection wheel apparatus 1 includes an end and swings the detection wheel carrier 12 be enclosed within on axis of swing 3, is rotatably connected on the engaged wheel 11 that detects wheel carrier 12 other end bottoms and is arranged on and detect the lip-deep magnet steel 14 of wheel carrier 12;
Described spring leaf 5 one ends are clipped between main frame 4 and band spring 7, and the other end is pressed in to detect and makes stressed the pressing to all the time of engaged wheel 11 detect main drive shaft 8 on wheel carrier 12, detects on main drive shaft 8 so engaged wheel 11 is attached to all the time;
All Hall elements 6 are arranged on pcb board 9 and towards magnet steel 14, and corresponding one by one with magnet steel 14;
Have the through hole 51 in magnetic field that is used for sensing that magnet steel 14 of its correspondence for Hall element 6 on described spring leaf 5.
the utility model is arranged on when using on currency counting and detecting machine, bank note is under the turning effort that detects main drive shaft 8, along with the rotation that detects main drive shaft 8 from detecting main drive shaft 8 and detecting when passing through between the engaged wheel 11 of wheel apparatus 1, different-thickness due to the bank note different parts, each detects wheel apparatus 1 can up do in various degree fluctuation along with the thickness of bank note, detect magnetic field on magnet steel 14 on wheel apparatus 1 this moment and also can do in various degree fluctuation thereupon, so on pcb board 9, the Hall element 6 corresponding with magnet steel 14 will be sensed the magnetic fluctuation degree on magnet steel 14, thereby judge exactly the thickness of that section bank note, different magnetic field degree of fluctuation through whole Hall elements 6 just can be measured each thickness to section of entire paper coin, thereby more accurately measure the thickness of bank note, differentiate more accurately the true and false of bank note with this, so more reasonable structure of the present utility model, improve the pseudo-success ratio of banknote inspection by the thickness that more accurately detects the bank note zones of different.
