Determinator and the method for the currency examination shell fragment angle change of the present invention are mainly used in finance device such as automatic teller machine On currency checking module shell fragment angle change be measured.
When bank note is by currency checking module, shell fragment can the most up displacement, pop one's head in now by thickness transducer The change in displacement of detection shell fragment determines the thickness of banknote.The shell fragment of currency checking module is generally multiple forming a line, and is assemblied in and tests In the upper element of paper money, when currency examination device merges up and down, when not crossing banknote, shell fragment can by the pressure of assembly from below upwards Spring back to certain angle, be now the initial position of shell fragment;When banknote passes through, shell fragment can move according to the thickness of banknote accordingly Distance, be now arranged on the thickness transducer above shell fragment and just can detect that corresponding situation of change, the most just determine banknote Thickness.
For reducing the error of sensor detection, thickness transducer is when detecting shell fragment change, it is desirable to each shell fragment after assembling Initial position keep consistent as far as possible, therefore before carrying out Product Assembly, the loading angle situation of change of shell fragment need to be carried out point Analysis.The determinator of the currency examination shell fragment angle change of the present embodiment, by simulation shell fragment stressing conditions in currency checking module, comes Measure each shell fragment angle of shell fragment after by same pressure.
The determinator of the currency examination shell fragment angle change of the present invention uses shell fragment clamping device 40 to grip shell fragment one end, The other end, by regulation pressure apparatus and the weight of counterweight, regulates the pressure roll 62 pressure N to shell fragment 30.As setting pressure N, The shell fragment support 34 of shell fragment 30 will produce corresponding displacement due to the effect in the vertical direction bearing pressure.Displacement transducer 80 Installing and select two fixing points, spacing is a, two measuring points of the most corresponding shell fragment, can demarcate shell fragment angle by change in displacement The coordinate of two measuring points before and after change.During test, obtain two mensuration on the front shell fragment of pressurization respectively by displacement transducer The coordinate of point is respectively A0(x1,y1),B0(x2,y2);After pressurization there is angle change in shell fragment 30 along fixed position, and now displacement passes Two measuring point coordinates of the shell fragment that sensor measures become A1(x′1,y′1),B1(x′2,y′2), record test data, to carry out angle Degree calculates.
The present invention currency examination shell fragment angle change assay method can Accurate Determining shell fragment in the case of by certain pressure Angle changes, to obtain the qualified shell fragment sample meeting design, for thickness transducer in currency checking module to banknote thickness essence True detection, to improve the quality of the currency checking module product of the finance devices such as automatic teller machine.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but also Therefore the restriction to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that, for those of ordinary skill in the art For, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these broadly fall into the guarantor of the present invention Protect scope.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
