Description
Invention field
The present invention relates to a kind of Coin acceptor, particularly relate to a kind of be suitable for the comprising coin in different induction characteristic zone such as the Coin acceptor of bimetallic coin.
Background of invention
As everyone knows, Coin acceptor will be differentiated the coin of different Currency Types and denomination, at our BrP GB-A-2, introduce an example in 169,429.This Coin acceptor comprises a Coin sideway, and coin passes a monitor station by its periphery along this slideway, and at this, coin is finished a series of inductance measurements to its interarea, so that produce the material of Mark Detection coin and the parameter signal of tenor.With the coin parameter signal digitizing so that digitized coin parameter data are provided, then with above-mentioned data and storage data relatively by microcomputer, otherwise so that determine detected coin qualification or.If confirm that coin is qualified, microcomputer is then controlled one and is received gate, so that coin enters receiving cable.Otherwise, receiving gate and then keep non-operating state, coin then enters the rejection passage.
The coin data of storage is represented the acceptance value of coin parameter data.Cun Chu data can be represented with the digital value of signal in theory, but in fact, because the difference of coin itself, the coin parameter data will change with coin is different; Its result will store the window data that conforms to coin parameter data qualifier value window usually.The width of this window is comprehensive between some factors.In order to reach gratifying discriminating between genuine note and the counterfeit money, should make window width narrow as far as possible.Yet, if window is too narrow, owing to the danger that genuine note is rejected appears in the fine difference between the genuine note characteristic.

Detailed Description Of The Invention
Coin acceptor shown in Fig. 1 to 5 comprises the Coin acceptor of more than one kind of coin, and this Coin acceptor can be confirmed many coins of different Currency Types and denomination, comprises bimetallic coin, for example comprises a complete set of coin of the Britain of new thermometal ￡ 2.00 coins.
Summary shows the actual disposition figure of Coin acceptor among Fig. 1.This Coin acceptor comprises that one is provided with the housing 1 of Coin sideway 2, and during detection, coin 3 passes coin monitor station 4 forward along these slideway 2 edges from entering the mouth, and then, falls towards gate 5.When coin passes monitor station 4, will detect each coin respectively.If it is genuine note that testing result shows, 5 at gate is opened, so coin can be sent into receiving cable 6; Otherwise 5 at gate remains closed, and coin then deflects to rejects passage 7.Pass the coin track with dashed lines 9 of Coin acceptor briefly illustrates for coin 8.
Coin monitor station 4 comprises three coin sensing coil device C1 that dot, C2a, and b and C3a, b, above-mentioned coil device energising is so that produce inductive coupling with coin.In addition, be provided with the 4th coil device C4 in the receiving cable 6 below gate 5, confirmed whether qualified coin has in fact entered receiving cable 6 so that detect.
The geometric configuration of coin has nothing in common with each other, and is by means of main oscillations shown in Figure 2, and circuit and interface circuit 10 are switched on to it with different frequencies.During detection, in coin, produce eddy current by coil device.Different inductive coupling between three coils and coin shows the notable difference of coin characteristic.As coin and coil device C1, C2, the function of different induction coupling between the C3, main oscillations and interface circuit 10 produce three corresponding coin characterisitic parameter signal X1, X2, X3.Coil device C4 produces corresponding signal X4.Can produce signal X1, X2, X3 and the X4 of coin characterisitic parameter by known many different modes.At our BrP GB-A-2, a kind of mode has been described in detail in detail in 169,429, in this patent, coil is located in the resonant circuit separately that keeps its natural resonance frequency when coin passes coil.This frequency is according to being offset because of the coil impedance transition principle with the generation of coin inductive coupling.This impedance variation makes amplitude and frequency all produce deviation.As described in the prior art, monitoring amplitude peak and with its digitizing, so that each coil is provided the parameter signal X of coin, during passing coil channel by means of coin, the magnet excitation frequency of coil is remained on its free-running frequency value, give prominence to amplitude excursion, so that help the identification between the coin.Yet, can adopt alternate manner to produce coin parameter signal X, the frequency departure that produces during by coil as the monitoring coin, list of references is seen GB1,452,740.
Be the reliability of guaranteeing that coin is differentiated, three parameter signal X1 that coin produces when micro controller 11 inputs detect, X2, X3, above-mentioned controller links with the storage arrangement that electricity can be wiped programmable read-only memory EEPROM12 form.Coin parameter signal that coin sent when micro controller 11 will detect and storing value comparison corresponding in EEPROM12.This storing value is to have the window storage of high-low limit value.Therefore, if each coin parameter signal X1, X2 and X3 belong to the corresponding to window ranges of genuine note of relevant particular types, show that then this coin is qualified, otherwise then reject.If qualified, as then to provide a signal to deliver to control gate 5 shown in Figure 1 on the circuit 13 driving circuit 14 is so that deliver to receiving cable 6 with coin.Otherwise 5 at gate is not opened and coin is delivered to rejection passage 7.
Micro controller is coin parameter signal X1, and X2 and X3 conform to different classes of coin, and many not on the same group control window datas are compared, thereby Coin acceptor can receive or reject the coin more than a piece of a cover designated currency.If this coin is qualified, detects this coin by coil device C4 and whether pass through along receiving cable; And install 10 corresponding data X4 is sent to micro controller 11, on being identified as the circuit 15 of quantity of money of qualified coin, indication provides an output valve subsequently.
Now will set forth the configuration of cell winding in more detail.Refer again to Fig. 1, in the usual way, Coin acceptor has a hinged coin door 16 on the axle 17 of its housing 1.Show as Fig. 3 is detailed, between the wall 19 of housing 1 and door 16 inwalls 18, be provided with the slideway 2 of coin.This slideway 2 comprises the boss 20 of inclination on door 16, and pickup wire coil apparatus C1, C2 and C3 are passed in the above-mentioned slideway operation downwards of coin week edge.In Fig. 3, show that coin 8 is on the sloping platform 20 of slideway 2.As be known in the art, show gate 16 is offset to make-position by spring in Fig. 1 and 3, if but during the coin jam, this door also can outwards rotate from casing 1, thereby unclamps nipped coin and make it drop down onto rejection passage 7.
Again referring to Fig. 1, coil device C1 comprises the coil and the independent coil on the bobbin of a circle not shown in the figures of installed inside of the wall 19 of housing 1, compare with the different classes of coin major-surface-area that Coin acceptor may be differentiated, above-mentioned coil has bigger area.Usually, coil device C1 external diameter is 14mm, and area is 154mm
2When coin 8 passed coil device C1, the inductive coupling between coil and coin was the moment alternation, produced aforesaid coin parameter signal X1, and it is the mean value that detects the whole interarea inductance characteristics of coin basically that the area of coil C1 causes signal more greatly.
As shown in Figure 1, the coin 8 that will differentiate comprises a bimetallic coin, and comprises that in this example new face amount is the coin of ￡ 2.00.This coin 8 is discs, be provided with two opposed interarea 8a, a 8a ' and an outer circumference surface 8b, this coin by the inner core district 21 of first cupronickel and be centered around inner core district 21 peripheries alloy material second perimeter region or encircle 22 and form, at this, alloy refers to and comprises 76%Cu, the bronze of 4%Ni and 20%Zn.Two above-mentioned zones present different inductance characteristics to the pickup wire coil apparatus, will be coil device C1 and C2a therefore, the mean value of b.In addition, as previously mentioned, the joint between the district 21 and 22 may have the different opering characteristics of electric apparatus with regard to different coins, and this will influence coil device C1, the signal X1 that C2 produced, X2 value.Its result, coil device C1 and C2a, b itself may not necessarily provide the coin parameter signal that is enough to differentiate ￡ 2.00 coins and other classification coin and counterfeit money; Yet, adopting coil device C3a according to the present invention, b will solve an above-mentioned difficult problem.
Referring to Fig. 3, coil device C3a, b comprise a pair of coil block C3a on wall 19 inboards that are installed in Coin acceptor housing 1 and the wall 18 that is installed in door 16, C3b.Coil block C3a, its structure of C3b will form inductive coupling with the bimetallic coin 8 bronze rings 22 that will detect selectively, and promptly the cupronickel district with the coin center does not have tangible inductive coupling.
Each coil block C3a, b comprise that respectively the bobbin that is essentially tubular 23 of plastics pushes away assembling with the what is called half flute profile magnetic core made from ferrite sintered body 25 and closes.Magnetic core 25 comprises the tubular central head 26 that forms a through hole, so that reduce the quantity of used Ferrite Material; Also comprise a concentric periphery cylinder support lug 27 in addition.
Replace another program of bobbin, can center on a coil former coiled winding not shown in the figures, and the heating winding, softening its insulating material, thus form the self-supporting coil during cooling, then itself and half flute profile magnetic core 25 are pushed away to assemble and close.
Corresponding grooves pushes away assembling and closes in the flange of half flute profile magnetic core 25 and the wall, and therefore, the flange of assembly C3a 27 pushes away assembling with cylindrical groove 28 in the wall 19 and closes, and corresponding grooves 29 pushes away assembling and closes in the flange 27 of assembly C3b and the wall 18.The winding outside diameter d of coil 24
1Be 7.3mm.The inner diameter d that has the coil 24 of bobbin 23
2Be 2.78mm.The diameter that passes magnetic head 26 through holes is 2mm.In this example, coil block C3a, the end face 30 of b is spaced apart 6.24mm.The axial length of coil 24 is 2.78mm.The outside diameter d of half flute profile magnetic core 25
3Be 9mm, so the area A of the end face 30 of each coil device (promptly facing the end face of tested coin) is 63.62mm
2Assembly C3a, the winding 24 of b are electricity series connection.As Fig. 3 finding, coil block C3a, the set coil 24 of b is configured in the relative both sides of the coin B that detects along a common axis B.Therefore, when coin passed between the coil, common axis 8 was along the coin interarea 8a that detects, 8a ' horizontal expansion, and also the interarea 30 of coil 24 is towards the interarea 8a of coin, 8a '.
Well-known in the magnet coil structure, the magnetic field of a common solenoid is to concentrate along coil axes; Therefore, for each coil block C3a, b, magnetic field mainly concentrates in the ferrite head 26 of half groove magnetic core 25, and except that magnetic flux passes end face 30 zones that material around returns magnetic head 26 parts, by means of around ferrite flange 27 mainly in the loop of coil, forming around the magnetic flux of coil.Therefore, largely for the assembly C3a that walks coin, the sensitivity of b is confined to pass the coin zone between the magnetic head 26.As shown in Figure 3, assembly C3a, b be near Coin sideway 2 location, and coil dimension d3 should make the inductive coupling between coin and the coil only limit to second outskirt 22 of coin 8 basically, and tangible coupling do not occur in first inner region 21.May be more apparent from Fig. 4, when the concise and to the point illustration of this figure is passed gap between the coil when coin, coil block C3a, the relative size and the configuration of b and coin 8.From Fig. 3 as seen, 25 extensions of half groove magnetic core are lower than Coin sideway 20, so that the configuration of magnetic core 26 is aimed at the outer shroud 22 of coin 8.
The coin parameter signal X3 that produces when coin 8 passes coil device C3 is mainly determined by the characteristic in the bronze district 22 of ￡ 2.00 coins, and cupronickel district 21 or the joint distinguished between 21,22 can not have any significant effects to parameter signal X3.Therefore, coin parameter signal X3 and signal X1 and X2 each coin of being integrated as the complete Britain coin that comprises ￡ 2.00 coins provides one group of coin parameter signal of feature notable difference.
Find in the practice, from coil block C3a, the reading quite stable on the b, and might make coil point to the coin zone of relative no surface imperfection selectively.
Obviously, the above embodiment of the present invention is not limited to ￡ 2.00 coins that detect in the complete Britain coin, and is suitable for detecting bimetallic coin basically, and this type of coin exists in the complete coin of other country and also has a thermometal feature.The coin data that is stored among the EEPROM12 can be stored as the appropriate window data that is suitable for relevant coin or sign.Generally speaking, confirmed by means of the coil device that makes in the face of coin that as coil C3a, the area A of b is less than 72mm according to the present invention
2, this will guarantee that the coin zone that will detect has unique inductance characteristic, thereby reach the effect of improving identification.
Many changes and variation belong within the scope of the invention.For example, though coil device C3 comprises a pair of relative coil C3a in the embodiment of Fig. 1 to 5, b also can adopt an independent coil.
Each coil C3 may not be an annular.In fact, adopt coil square or that rectangle twines can realize above-mentioned advantage.
In addition, according to the currency that will differentiate, also can adopt the coil device C1 and the C2 of different configurations.Therefore, coil device C1 or C2 or its two compared to Figure 1 can be with respect to the diverse location location of Coin sideway 2.In addition, remove coil device C1, outside the C2, can on slideway 2, establish the coin sensor (not shown) of an optics at least, perhaps replace one of two coil devices with this.
In modification, the door 16 and the wall 19 of housing 1 can be provided with coil block C3a, and a series of grooves 28,29 that b uses allow it to install at diverse location, so that be suitable for the detection of different cover currency to greatest extent.In other words, the governor motion of increase can be set, will allow coil block C3a, the b adjusting position.
Coil block C3a, b may not only be used to detect the outskirt 22 of coin.Fig. 6 shows a modification, wherein with comprising and assembly C3a the series coil assembly C5a of b correspondence, the coil device C5 replacement coil device C2 of b.The configuration of this coil device C5 is first inner region 21 that is suitable for detecting selectively bimetallic coin 8.Along with coin rolls for 2 times along slideway, be sent to microcontroller 11 from the output signal X1 of coil C1, and pass the coil block C5a that allows selectively with inner region 21 couplings that will detect when coin inner region 21, in the time of between the b, reach a maximal value.The face area of this coil is enough to little of detection zone 21 selectively only.In gating signal display window process, coin parameter signal X2 represents to distinguish 21 inductance characteristic, is not distinguished the influence that engages between 22 or two districts substantially.
Coil block C3a, b and C5a, b may not be as previously mentioned must series connection, and can change connection so that as European patent EP-A-0,599,844 describedly carry out different inductance measurements.
In addition, coil block C3ab and/or C5a, b may not be provided with along boss 20, and may be located at other position in the Coin acceptor.Also some coil blocks can be become a row configuration.
Although the detection of Britain ￡ 2.00 bimetallic coins has been described in detail in detail in the embodiment of preamble, yet this Coin acceptor also can be used to detect the bimetallic coin of different currency, as Euro.Obviously, having the different coin zone of characteristic may the configuration difference.For example, coin may comprise the ring of more than one different metal composition.In addition, zones of different may not be a ring, and may be other shape.They are not must be metal all.They can comprise no coin material part, as the hole.
In addition, each zone can be the zones of different of the coin made by the same metal composition, and as 25 coin-dividings of dollar, this coin heart district therein has the very big corrugated surface that rises and falls, but more level and smooth in its surrounding zone.These different zones present different inductance characteristics, can detect respectively according to the present invention.
In a word, apparent, can comprise and assembly C3a that in the detection position of the presumptive area of the coin that will detect corresponding other coil block of b is so that detect the inductance characteristic of its significant difference.
Comprise coin at this used term " coin ", the article of feature product or other coin class.
