Detailed Description
In order that those skilled in the art will better understand the technical solution of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings and embodiments.
Referring to fig. 1, the invention provides an automatic teller machine with an abnormal banknote processing function, which comprises a teller machine shell 10, wherein a hollow banknote bin 1 is arranged at the upper part of the teller machine shell 10, and the banknote bin 1 is used for longitudinally placing banknotes to be taken out or stored by people;
the bottom surface of the left end of the bill bin 1 is connected with the right end of a power channel 4, a power channel guide roller 7 is arranged on the lower left of the bill bin 1, and the middle of the power channel 4 is wound on the outer wall of the power channel guide roller 7;
the left side of the banknote bin 1 is provided with a banknote friction wheel 3, the back of the banknote friction wheel 3 is connected with an output shaft of a banknote friction wheel motor 30, and the banknote friction wheel 3 is driven by the banknote friction wheel motor 30 to rotate clockwise or anticlockwise.
It should be noted that when a banknote is located between the banknote counting wheel 3 and the power channel 4, the banknote can move to the lower left along the power channel 4 under the action of the clockwise rotating banknote counting wheel 3, or move to the upper right banknote bin 1 under the action of the counterclockwise rotating banknote counting wheel 3.
In the present invention, three pairs of photoelectric sensors 5 are symmetrically arranged on the left and right sides of the power channel 4, and the three pairs of photoelectric sensors 5 are arranged side by side in the longitudinal direction (i.e. including a front pair of photoelectric sensors 5, a middle pair of photoelectric sensors 5 and a back pair of photoelectric sensors 5);
the three pairs of photoelectric sensors 5 are positioned on the left side and the right side of the banknote-grinding wheel 3 at the same time;
each pair of the correlation photoelectric sensors 5 is configured to send a timing trigger signal (for example, a step voltage signal) to the central control unit when any one preset denomination banknote to be detected passes through the correlation photoelectric sensor (which will block the light beam connection between the pair of the correlation photoelectric sensors 5) under the driving of the banknote-counting wheel 3;
the central control unit is configured to receive a timing trigger signal from the correlation photoelectric sensor 5 in real time, perform real-time timing, and when the timing trigger signals sent by three pairs of the correlation photoelectric sensors 5 are not always received simultaneously within a preset passing time length (for example, only one pair or two pairs at a certain time) the light beam connection of the correlation photoelectric sensor 5 is blocked, determine that the preset banknote with the banknote-counting and dispensing function performed by the banknote-counting wheel 3 is an abnormal banknote (as shown in fig. 2 to 6).
In the present invention, it should be noted that the preset passing time length is preset according to the needs of the user, and is preferably equal to the quotient of the length (i.e. width) of the broadside of the longitudinally placed preset denomination banknote divided by the rotation speed of the banknote rubbing wheel 3, that is, the time required for the broadside of the preset denomination banknote to pass through the pair of the opposite photoelectric sensors 5.
It should be noted that the selected banknote with the preset denomination is a RMB banknote with one hundred yuan, the length of the banknote is 155mm, and after the long side is folded in half, the length of the banknote is about 78mm, so the distance between two opposite photoelectric sensors cannot exceed 78mm, therefore, in the invention, the longitudinal separation distance between any two adjacent opposite photoelectric sensors 5 is preferably less than or equal to half the length (such as 78mm, 76 mm, etc.) of the banknote with the preset denomination.
In order to detect the preset face value bank notes with the problem of broadside folding in time, the central control unit is further configured to accumulate time (i.e., time during which light beams of the three pairs of the opposite photoelectric sensors 5 are connected and simultaneously blocked) in real time when receiving timing trigger signals sent by the three pairs of the opposite photoelectric sensors 5 at the same time, and determine that the preset face value bank note (i.e., the preset face value bank note passing through a position between the three pairs of the opposite photoelectric sensors 5 at present) with the banknote rubbing wheel 3 performing the banknote counting function is an abnormal bank note (such as the bank note shown in fig. 6) with the broadside folding when the accumulated time is smaller than or equal to the preset folding broadside blocking time value.
It should be noted that, when the preset denomination banknote is a RMB banknote with a denomination of one hundred, the standard length is 155mm, and the standard width is 77mm, at this time, if the rotation speed of the banknote rubbing wheel 3 is 1 m/s, the standard time required for one hundred-dollar RMB banknote, which is longitudinally placed and not continuously passing through the pair of the correlation photoelectric sensors 5, is about 77 ms, so that the preset passing time length can be set to be 77mm or 80 ms at this time, specifically, the preset passing time length can be set according to the needs of a user, and specifically, the preset passing time length can be less than or equal to the time required for the preset denomination banknote to pass through the pair of the correlation photoelectric sensors 5. At this time, the preset fold broadside blocking time value may be 38 milliseconds (for an abnormal banknote folded in half), or may range between 38 milliseconds and 77 milliseconds (for an abnormal banknote that is not folded in half but has the long sides folded in parallel). That is, the preset doubled broadside blocking time value is preferably equal to the quotient of the length (half width) of half broadside of the longitudinally placed preset denomination banknote divided by the rotation speed of the banknote rubbing wheel 3, that is, the time required for half broadside of the preset denomination banknote to pass through the pair of the correlation photoelectric sensors 5.
It should be noted that the power channel 4 has a through hole at the position corresponding to each pair of the opposed photoelectric sensors 5, so that when there is no banknote on the power channel 4, there is no shielding between each pair of the opposed photoelectric sensors 5, and thus no timing trigger signal is generated.
It should be noted that the banknote receiving module CS includes a banknote bin 1, a banknote pressing plate 2, a banknote grinding wheel motor 30, a banknote grinding wheel 3, a power channel 4 for transmitting banknotes, and a correlation photoelectric sensor 5 for detecting the width of the banknotes.
In the invention, in a concrete implementation manner, a first banknote receiving power wheel 61 is arranged at the bottom of the banknote bin 1, and a second banknote receiving power wheel 62 and a third banknote receiving power wheel 63 are arranged at the bottom of the right end of the power channel 4 at intervals;
a banknote receiving fourth power wheel 64 (namely the last banknote receiving power wheel) and the power channel first power wheel 41 are further arranged on the top surface of the middle of the power channel 4 at intervals, and the banknote receiving fourth power wheel 64 is located on the right side of the power channel first power wheel 41.
In a concrete implementation manner, the banknote receiving first power wheel 61, the banknote receiving second power wheel 62, the banknote receiving third power wheel 63, the banknote receiving fourth power wheel 64 and the power channel first power wheel 41 can be connected with a same power channel motor and driven by the same power channel motor to rotate.
In a specific implementation, the banknote receiving fourth power wheel 64 and the power channel first power wheel 41 are parallel to each other;
the length of the power channel 4 corresponding to the spacing between the banknote receiving fourth power wheel 64 and the power channel first power wheel 41 is less than or equal to half the width of a preset denomination banknote (e.g., 38mm for one hundred RMB), and the length of the power channel 4 corresponding to the spacing between the banknote receiving third power wheel 63 and the banknote receiving fourth power wheel 64 is less than or equal to half the width of a preset denomination banknote (e.g., 29mm for one hundred RMB).
It is noted that the first power wheel 61, the banknote receiving second power wheel 62 and the banknote receiving third power wheel 63 are not only adjacent to each other two by two, but also parallel to each other.
It should be noted that the banknote receiving first powered wheel 61 may be driven by an external motor (e.g. a power channel motor) to rotate clockwise or counter-clockwise.
In the invention, in a concrete implementation, the bottom of the bill bin 1 is provided with transversely distributed openings, and the top of the bill receiving first power wheel 61 is tangent to the openings, so that the bill receiving first power wheel 61 can be contacted with the bottoms of bills placed in the bill bin 1 through the openings, when the bill receiving first power wheel 61 rotates anticlockwise, the bills placed in the bill bin 1 can be driven to move leftwards, and the bills enter the power channel 4 under the driving of the clockwise friction of the bill friction wheel 3.
In the invention, in a concrete implementation, a banknote pressing plate 2 is arranged in the banknote bin 1, and the banknote pressing plate 2 is used for pressing banknotes placed in the banknote bin 1.
In the present invention, the upper portion of the depositing and dispensing machine housing 10 is provided with a shutter 20, and the shutter 20 is opened when bills are put into and taken out from the bill magazine 1.
In a specific implementation, the power channel 4 may be a banknote conveying channel commonly used in existing automated teller machines.
In the invention, when the central control unit judges that the preset bank note with the bank note rubbing and discharging function performed by the bank note rubbing wheel 3 is an abnormal bank note, in order to timely return the bank note and remind people to timely arrange and correct the bank note so as to prevent the bank note from blocking inside the cash recycling machine, the central control unit is also connected with the bank note rubbing wheel motor 30 and is used for sending a stop operation signal to the bank note rubbing wheel motor 30 and controlling the bank note rubbing wheel motor 30 to stop operation when the preset bank note with the bank note rubbing and discharging function performed by the bank note rubbing wheel 3 is judged to be the abnormal bank note.
In addition, the central control unit is further configured to send a reverse rotation signal to the banknote counting wheel motor 30 after controlling the banknote counting wheel motor 30 to stop operating for a preset banknote clearing time length (which may be equal to or longer than a time length required for normally clearing the banknotes on the power channel 4, for example, 5 seconds), and control the banknote counting wheel motor 30 to rotate counterclockwise, so that the banknote counting wheel 3 can reversely count the banknotes thereon back to the banknote bin 1, and therefore, the banknote counting operation can be performed again.
In addition, the central control unit is also used for controlling the banknote friction wheel motor 30 to rotate anticlockwise, so that the banknote friction wheel 3 reversely rubs the banknotes on the banknote friction wheel to return to the banknote bin 1, and simultaneously sending a preset acousto-optic early warning prompt to a user to prompt that the current user has abnormal banknotes, needs to be rearranged in time, and arranges the abnormal banknotes into normal banknotes without any folding.
In a specific implementation of the present invention, the preset acousto-optic warning prompt may be a pre-recorded sound segment and a flashing prompt emitted by an L ED light emitting diode.
In a specific implementation of the present invention, the central control unit may be any module with a signal processing function, for example, a central processing unit CPU, a digital signal processor DSP, or a single-chip microcomputer MCU.
It should be noted that, for the invention, the layout of the correlation photoelectric sensor and the layout of the power wheel are adjusted on the existing banknote rubbing mechanism, the state of the banknotes is monitored in real time through the correlation photoelectric sensor, the state of the banknotes to be rubbed down is monitored, if the banknotes are found to have an abnormal condition of super-oblique or super-narrow, the banknote rubbing wheel motor is immediately stopped, the banknote rubbing wheel is reversely rotated to rub the banknotes back, the user is reminded to take out the banknotes for rearrangement, and then the banknotes are put in after arrangement, so that the banknotes rubbed down by the banknote rubbing wheel of the CS banknote receiving module are all the banknotes with normal shapes, the banknote quality is ensured from the source, the banknote blocking rate of a machine core in the automatic teller machine is reduced, and the reliability is improved.
In order to more clearly understand the technical concept of the present invention, the following describes the implementation process of the technical solution of the present invention with reference to specific embodiments.
The selected banknote with the preset denomination is RMB with the denomination of one hundred, the length of the banknote is 155mm, after the long edge is folded in half, the length of the banknote is about 78mm, so that the distance between two opposite photoelectric sensors cannot exceed 78mm, and therefore, in the invention, the longitudinal distance between any two adjacent opposite photoelectric sensors is smaller than or equal to half the length (such as 78mm, 76 mm and the like) of the banknote with the preset denomination.
The three pairs of photoelectric sensors are arranged side by side and must have a sensor to detect when a banknote passes. The width of the banknote after folding the short sides in half is approximately 38mm,
the length of the power channel 4 corresponding to the interval between the banknote receiving third power wheel 63 and the banknote receiving fourth power wheel 64 cannot exceed 38mm, otherwise, the ultra-narrow banknote is easy to stay at the power blind spot.
Example one
Referring to fig. 2, for the banknote 100 with the preset denomination, if the side a enters first, only the front pair of the opposed photoelectric sensors can detect (i.e., is blocked to send out a timing trigger signal), and the middle and rear pairs of the opposed photoelectric sensors cannot detect, then the central control unit can judge that the banknote is an abnormal banknote; if the side B of the preset denomination banknote 100 enters first, the front and rear pairs of opposed photoelectric sensors can detect the side B, and the middle pair of opposed photoelectric sensors cannot detect the side B, the central control unit can judge that the banknote is an abnormal banknote.
Example two
Referring to fig. 3, for the preset denomination banknote 100, if the side C enters first, the three pairs of opposite photoelectric sensors are simultaneously shielded to send out timing trigger signals, but when the banknote leaves, only the middle pair of opposite photoelectric sensors can be shielded, and the front and rear pairs of opposite photoelectric sensors cannot be shielded, so that the central control unit can judge that the banknote is an abnormal banknote; if the D edge enters first, the banknote can be judged to be abnormal.
Examples three and four
Referring to fig. 4 and 5, for the banknote 100 with the preset denomination, whether the F-side and the H-side are advanced or the E-side and the G-side are advanced, the banknote can be detected and judged as an abnormal banknote by the central control unit.
EXAMPLE five
Referring to fig. 6, for a preset denomination banknote 100, when the banknote enters between three pairs of photoelectric sensors, three pairs of photoelectric sensors are shielded to send out timing trigger signals, time (i.e. time for which light beams of the three pairs of photoelectric sensors 5 are simultaneously connected and shielded) is accumulated in real time, and when the accumulated time is less than or equal to a preset doubled-up broadside shielding time value (e.g. 38 milliseconds), the preset denomination banknote which is currently subjected to the banknote-rubbing and dispensing action by the banknote-rubbing wheel 3 is judged to be an abnormal banknote (such as the banknote shown in fig. 6) after being doubled in broadside, and if the rotation speed of the banknote-rubbing wheel 3 is 1 m/s, the passing width of the banknote is less than 40 mm.
Aiming at the typical abnormal bank notes, as long as the abnormal bank notes can be detected, the abnormal bank notes can be reversely rubbed back by controlling the rotation of the bank note rubbing wheel, returned to a user, rearranged and rubbed again.
For the abnormal banknote processing function, the specific operation flow comprises the following steps:
the first step is as follows: the banknote receiving module CS prepares for banknote discharge, starts the banknote friction wheel motor 30 to rotate in the forward direction, and the banknotes enter the power channel 4 from the banknote bin 1; the cash discharging mode of the cash receiving module CS is the same as the existing processing mode, namely, the cash is discharged by rubbing through the cash grinding wheel 3;
the second step is that: the state of the bank note is detected through three pairs of counter photoelectric sensors 5 at the inlets of the bank note receiving module CS, when the central control unit does not always receive timing trigger signals sent by the three pairs of counter photoelectric sensors 5 at the same time within a preset passing time length (for example, only one or two pairs of counter photoelectric sensors are shielded at a certain time), it indicates that the bank note is in a very inclined state at the moment, and the three pairs of counter photoelectric sensors 5 cannot be shielded at the same time, the central control unit sends a stop signal to the banknote grinding wheel motor 30, and controls to stop the banknote grinding wheel motor 30 (the motor is stopped immediately, and the deceleration stop is not required);
it should be noted that the inclined banknote will also stay between the third powered wheel 63 and the fourth powered wheel 64, since the distance between these wheels can be 29 mm. When the current bank note is detected to be an abnormal bank note with the wide edge folded in half, namely the bank note is ultra-narrow (smaller than the width of the wide edge folded in half), the central control unit is also required to send a stop signal to the bank note rubbing wheel motor 30 to stop the bank note rubbing motor immediately, and at this time, the bank note leaves the correlation photoelectric sensor 5, but since the correlation photosensor 5 is located before the banknote receives the third powered wheel 63, the distance of the length of the corresponding powered channel 4 between the banknote receiving third powered wheel 63 and the banknote receiving fourth powered wheel 64 is 29mm, the distance of the length of the corresponding power channel 4 between the banknote receiving fourth power wheel 64 and the power channel first power wheel 41 is 38mm, therefore, the ultra-narrow abnormal bank note still stays on the power wheel of the bank note receiving module CS, and cannot be taken away by the motor of the power channel when the bank note rubbing wheel of the bank note receiving module CS is stopped.
The third step: when the banknote friction wheel of the banknote receiving module CS stops rotating, the motor of the power channel normally operates, and the banknotes in the power channel are completely emptied. The banknote rubbing wheel in the banknote receiving module CS reversely rubs the banknotes clamped at the banknote rubbing wheel back and returns the banknotes to the user, and the user is reminded to rearrange the banknotes.
In summary, compared with the prior art, the automatic teller machine with the abnormal banknote processing function provided by the invention can detect and find the abnormal banknote problem in the depositing process of the automatic teller machine in time, avoid the damage of the abnormal banknote to the automatic teller machine, ensure the service life of the automatic teller machine, be beneficial to improving the market application prospect of automatic teller machine products, and have great production practice significance.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
