After mark precision can reach arithmetic point, four meet measurement measurement requirement, as shown in Figure 3；So circulate, you can insertion is a large amount of at a high speed
Camera picture, realizes setting insertion point, scaling, obtains the equal sized purpose of physical dimension and practical structures in picture,
And editing and processing is carried out to picture in the process, and a large amount of bank note front ends fixed point is marked, their distribution substantially is bent
Line, is marked with circles mark, as shown in figure 4, thus having reappeared the track of bank note crosses paper money, is connected bank note leading edge end points afterwards and is drawn
Movement locus, as shown in Figure 5.
A kind of better simply function approximation need to be sought according to the lot of experimental data for measuring to solve, a most young waiter in a wineshop or an inn for curve matching
Multiplication is in this kind of Data Processing in Experiment and error analyses are solved using the efficiency that widely, can improve data processing and accurate
Degree.Realize the method for least square of curve matching in the present invention using matlab software programmings, experimental data is processed, is entered
And obtain the bank note displacement curve figure of whole crosses paper money process.
Additionally, in order to reduce the vibration produced by the operating of currency counting and detecting machine definite-purpose motor to bank note kinestate shadow
Ring, be that the motor that platform is equipped with is design model YYD40R-4H definite-purpose motor and is non-with the connected mode of platform
The way of contact.Transmission between gear is not toothed belt but circular strap transmission, can so increase the stationarity of transmission, prevent
Only belt slippage phenomenon.
During experiment, three below step is largely divided into：First step is that measurement driven pulley is with the relative angle of drivewheel
When 0 °, inspection bank note whether can smooth crosses paper money, and using the crosses paper money situation of high speed camera collection bank note；Second step is measurement
In left and right dynamic change, whether (different angles, 1 °, 2 °, 3 ° ... .10 °) can be suitable from the relative angle of drivewheel for driven pulley
Sharp crosses paper money, and bank note crosses paper money situation is gathered using high speed camera；Third step is to arrange the picture captured by high speed camera, and
Process in importing to PC.
Specific implementation is as follows：
1) first the connection of experiment test equipment is completed, then high speed camera and spotlight is positioned.
2) PC, high speed camera, spotlight are opened, warming-up about half an hour, it is determined that the instrument in experimental test procedures
Device keeps stable state.
3) it is the irradiation position for adjusting spotlight that experiment starts front most important work, and adjusting which makes which to appropriate position
Light intensity reaches the purpose that high speed camera can collect picture rich in detail, and after adjustment, high speed camera is obtained in that
.
4) three angle index flaps on visualization point currency examination model machine side plate are adjusted, the relative position of driven pulley and drivewheel is determined
Relation is put, starts laboratory table motor, bank note is placed from note input mouth and determine that bank note, completely by walking paper money wheel group, laboratory table motor is stopped
Only, it is determined that collecting all images for entirely walking paper money process.
5) view data for collecting above-mentioned steps is arranged and is stored on PC, to carry out the process of next step.
6) in PC according to above-mentioned software image processing method, bank note leading edge end points in every pictures is carried out one by one
Demarcation, so as to obtain the displacement variable between the displacement of the relative reference origin of bank note leading edge end points and each leading edge end points.
Wherein, 44 bank note motion pictures are collected altogether by the whole paper currency transmission process of high speed camera collection experiment under 10 ° of left avertence,
Wherein 33 have been reacted the whole process that bank note is transmitted in the presence of paper money wheel group is walked, and high speed camera sample frequency selects setting
It is 500 frames/second, that is to say 0.002s/.By analysis high speed camera gather 33 images used by the time be about 0.002 ×
33=0.066s, that is to say that the time of individual bank note motion is 0.066s.Obtain position of the bank note leading edge end points with respect to reference origin
Move and the displacement variable between each leading edge end points is as shown in table 1 below.

Method of least square is realized using matlab software programmings, the carrying out of experimental data is processed, the result after process is such as
Shown in Fig. 6, by can be seen that in figure that the curvilinear trend for actually fitting is roughly the same with model emulation curve, bank note is into accelerated motion
State, entering the paper money stage in phantom in 0.03s completes, followed by walking the paper money stage.Because the paper for being derived before
The coin equation of motion is set up according to the friction model of amendment, and in some models, set parameter value is certain to actual parameter
It is different.And emulation be assume bank note be thin film rigid body under conditions of carry out can not observe bank note attitudes vibration, imitate
In true mode, the initial condition of bank note motion is also differed with the initial condition of actual banknote motion, to actual design directive significance
Less, do not have the curve movement that the data directly actually measured draw more convincing to studying bank note kinestate.
Three angle index flaps are chosen at 0 °, 2 ° of left avertence, 5 °, 10 °, 2 ° of right avertence, 5 °, 10 °, this seven groups of typical diverse locations
The time that relation walks the transmission bank note consumed by paper money process is as shown in table 2 below, the tilting situation such as table 3 below institute at bank note note output angle
Show, the frequency acquisition of high speed camera is set as 500 frames/second, that is, the time that a pictures are consumed is 0.002s.
Seven groups of table 2- is different, and angle walks paper money process statistics
Wish when currency counting and detecting machine is designed the mechanism that designs can smooth crosses paper money and The faster the better for transmission speed, so can be with
Counting speed is greatly improved, work efficiency is improved.By the date comprision in above table, transmission time is with right avertence angle
The increase of degree and increase, reduce with the increase of left avertence angle, it is ensured that in the case of the smooth crosses paper money of transmitting procedure and not card paper money, it is left
There is minima in the partially a certain number of degrees, it is ensured that walk paper money transmitting procedure and consume the most short time.
Table 3- deflection angles and note output Angle Measurements
| Measurement group | Drivewheel and driven pulley centrage corner (°) | Note output angle (°) |
| 1 | 0° | 0° |
| 2 | 2 ° of right avertence | 3° |
| 3 | 5 ° of right avertence | 6° |
| 4 | 10 ° of right avertence | 12° |
| 5 | 2 ° of left avertence | -4° |
| 6 | 5 ° of left avertence | -3° |
| 7 | 10 ° of left avertence | -10° |
By above table induction and conclusion, note output can be changed with drivewheel relative position relation by changing driven pulley
Angle, that is to say the direction of bank note subsequent time transmission.And driven pulley exist with note output angle with the relative angle size of drivewheel it is close
The relation cut, can see that from table driven wheel angle is substantially equal in magnitude with bank note note output angle.
In sum, by above experimental technique it is concluded that：Bank note bank note leading edge under different deflection angles exists
Warpage can occur when will move out roller pair, warpage angle is roughly the same with deflection angle.It is left in driven pulley relative position
When partially, paper currency transmission is most smoothed out, efficiency of transmission highest, and bank note warpage degree is minimum, and individual bank note transmission time is most short to be
0.076s。
The examples of implementation of the above are only the preferred embodiments of the invention, not limit the enforcement model of the present invention with this
Enclose, therefore the change made by all shapes according to the present invention, principle, all should cover within the scope of the present invention.
