Description
Technical field
The present invention relates to a kind of device of flattening bending banknote more particularly to a kind of bending banknote exhibitions based on contact heating
Leveling device can be used as a module and be mounted in ATM machine, plays the role of flattening bending banknote, belongs to automatic teller dress
Standby technical field.
Background technique
The biography paper money module of ATM machine is a kind of typical media transportation mechanism, needs paper banknote high speed being sent to finger
Positioning is set.Banknote can occur bending and deformation in the storing process in ATM machine because of the comprehensive function of factors such as power, heat, from
And banknote is influenced in the transmission process for passing paper money module.It is a kind of typical the reason is that banknote resting period mistake in curved reel
It is long, due to the viscoelastic property that banknote material has, under conditions of the deformation added outside is constant, it may occur that stress relaxation, banknote
Permanent bending deformation occurs.If the bending degree of banknote itself is excessive, the beauty of banknote will affect, and lead to card paper money rate
It significantly improves.In order to reduce the card paper money rate of ATM machine, need to be thought of as overbending in the design process that ATM machine passes paper money module
Banknote corresponding flattening function is provided.
Flattening process is exactly that banknote is allowed to become the lesser state of bending degree from the biggish state of bending degree, substantially
One process for allowing banknote that back-flexing deformation occurs；Since the transmission process of the banknote in ATM machine requires biography paper money speed fast, therefore
And be difficult to realize flattening by prolonged viscoelastic deformation, can only by the external load of deep camber, make banknote
Plastic deformation, and then realize back-flexing, that is, it flattens.It is this by external force allow banknote occur back-flexing when, the external force of load
" load curvature " can be used, i.e., be described by the bending curvature of banknote under external force, if producing plastic deformation, banknote
Permanent bending deformation can occur after external force release.
Banknote is as handled object, and in addition to paper, the material of some banknotes also is plastics, such as in the big benefit of Australia
The countries such as Asia, Vietnam, plastics paper money are widely used.Paper and plastics are all the material with complex of high molecular polymer composition, power
Learn the function that characteristic is temperature.With the variation of temperature, under the conditions of same stress loading, can show different should be cashed
As.Power and temperature are to influence the principal element of flexible media bending deformation.
Each ATM machine manufacturer currently on the market provides the product comprising flattening functional module not yet.It is ground some
In studying carefully, the technical solution that some methods by mechanics, calorifics are flattened is provided；One of which is by corrugation rolls to paper money
Ticket carries out reinforcement operation, improves the bending of banknote stiffness reduction, and such scheme be easy to cause banknote to tear；Second is to pass through belt
The fillet for being 2mm by radius with banknote loads great counter curvature to banknote, so that reversed plasticity shape occurs for banknote
Become, is flattened；Although the program may be implemented to flatten, but because to cause banknote speed cannot by the track of minor radius
Raising, simultaneously meeting Fast Wearing belt；The third is the height that the copper rod for being about 30mm by a diameter is heated to 160 DEG C or more
Temperature, while banknote being allowed to pass through close to its outer rim flatten etc. scheme, although the program so that reverse strain occurs for banknote
Also flattening effect may be implemented, but the thermal inertia of copper rod is too big, it is difficult under the conditions of current power and operating ambient temperature
Realize the real-time control of surface temperature, while the damage of the excessively high plastic structural part for be easy to causeing surrounding module of temperature heated.
Summary of the invention
The object of the present invention is to provide a kind of bending banknote flattening devices based on contact heating, it is made not destroy banknote
In the case where, cause curved papery or plastic note to carry out back-flexing to because of long-term storage, reduces the card paper money rate of ATM machine.

Corresponding relationship of the Fig. 1 between 100 yuans of banknote bending curvatures and action.The bending deformation of banknote can be with
With " action " or " curvature " Lai Hengliang of banknote.Relationship between action and curvature is simple geometrical relationship, for a certain
A curvature, after arc length determines, so that it may calculate corresponding action by geometry derivation.Particularly, for 100 yuan of people
People's coin is fixed value 77mm, action and curvature can be calculated by geometric since its arc length is exactly the width of banknote
Corresponding relationship, as shown in Figure 1, horizontal axis is curvature, the longitudinal axis is action, as can be seen from the figure both in sizable range
With linear relationship.If can be read by Fig. 1, curvature is about for example, its action of banknote is 10mm
0.14mm-1。
Experimental studies have found that paper and plastics for manufacturing banknote meet bending below in certain temperature range
Deformation rule: becoming larger with load curvature as the temperature rises, and the Curvature varying amount after banknote release is bigger.Thus in determination
When the design parameter of structure, need to know initial banknote curvature range, by banknote curvature model to be achieved after flattening device
It encloses, and then calculates corresponding Curvature varying amount, according to Curvature varying amount and temperature and load the limitation of curvature itself come really
Fixed final structural parameters.In general, load curvature is with biography paper money track or certain Radius with a certain radius of curvature

Unit is DEG C；R is the radius of exhibition roller used, and unit mm, value range is 8mm≤r≤30mm, and characterization banknote is loaded curved
Bent external force.
Due to banknote by be bent flatten with by the smooth deformation process as being substantially that buckles, according to this experience
Formula will realize a certain specific flattening effect (being indicated with Δ y), can give series of temperature (being indicated with T) and load is bent
The combination of rate (being characterized with r, be the inverse of r), these combinations can realize the flattening effect of requirement, can be therefrom when implementing
Select low-power, the scheme of low-calorie paper money rate.
