It is.
[0033]
FIG. 1 shows a schematic configuration of a paper sheet handling apparatus according to a first embodiment of the present invention. This paper sheet handling apparatus is built in, for example, an automatic teller machine that performs deposit / withdrawal transactions of banknotes. It is what.
The bill deposit / withdrawal port 202 is a place where a customer deposits / withdraws bills. Although not shown, the banknotes deposited into the deposit / withdrawal port 202 are separated one by one by a separation mechanism provided here and sent to the discrimination unit 203.
[0034]
The discrimination unit 203 determines the authenticity of the banknote, the denomination, and the like. The denomination boxes 204, 204, and 205 store banknotes by denomination. The simple discrimination unit 207 determines the denomination and number of banknotes. The safe 208 is a box for storing banknotes and can be removed outside the banknote handling mechanism 201. This safe has a storage unit 208a for storing banknotes, and a temporary stacker so that the space inside the safe is divided into upper and lower parts above the safe 208 so that the banknotes of the banknote handling device 201 can be handled so as not to be mixed with the banknotes in the storage unit 208a. 208b is provided. The conveyance path 210 is arranged with two belts facing each other, and a banknote is sandwiched between the belts to convey the banknote. These banknote handling elements have substantially the same configuration and function as those incorporated in a conventional automatic cash transaction apparatus described in, for example, JP-A-1-237791 and JP-A-1-69426.
[0035]
FIG. 4 shows the flow of the operation of re-identifying rejected banknotes by the paper sheet handling apparatus according to the present invention built in the cash transaction apparatus, and the operation of the first embodiment shown in FIG. 1 using this figure. Will be explained. The reject banknote means a banknote whose denomination or number of sheets has not been determined by the discrimination units 203 and 207 during handling of the banknote.
[0036]
At the time of withdrawal, the banknotes separated and taken out one by one from the denomination boxes (denoted by reference numerals 204, 205, and 206 in FIG. To do. The banknotes successfully identified by the identification unit 207 are conveyed to the deposit / withdrawal port 202 and discharged to the customer. On the other hand, for the indeterminate banknote whose denomination and number of sheets cannot be discriminated, the banknote state detection unit 211 inside the apparatus detects the banknote conveyance state, and the skew / shift correction mechanism 209 based on the detection information. The skew state of the bill and the shift state translated from the normal position are corrected. Thereafter, the corrected banknote is again discriminated from the denomination and the number of sheets by the banknote discriminating unit 207, and the banknote whose amount and denomination are determined is conveyed to the deposit / withdrawal port 202. On the other hand, the banknote state detection part 211 detects the banknote conveyance state again for the banknote whose amount and denomination are indeterminate. The above operation is repeated until the denomination and number are determined.
[0037]
With the configuration described above, it is possible to realize a paper sheet transaction apparatus that can re-identify rejected banknotes and determine the type and number of sheets. In addition, by using such a paper sheet handling device as a banknote transport device in an automatic teller machine, it becomes possible to automatically scrutinize bills in the automatic transaction device and to improve the efficiency of cash management operations of financial institutions. Can do.
[0038]
Further, even when it is necessary to recount banknotes in the apparatus, the total banknote amount can be determined automatically without generating unknown banknotes. Moreover, by this, what is called a reject banknote is lose | eliminated and the storage box only for a reject banknote can be made small, or can be deleted.
[0039]
FIG. 5 shows another example of the operation of re-discriminating rejected banknotes generated at the time of withdrawal of banknotes in the paper handling apparatus according to the present invention built in the cash transaction apparatus. Using this figure
The operation of the first embodiment shown in FIG. 1 will be described.
At the time of withdrawal, the banknotes are separated one by one from the denomination boxes (denoted by reference numerals 204, 205, 206 in FIG. 1) stored in the denominations, and the taken out banknotes are identified with the denomination by the discrimination unit 207. Discriminate the number. When an indeterminate banknote whose denomination and number cannot be discriminated by the discrimination unit 207 is generated, the separation from the denomination boxes 204, 205, 206 is stopped or delayed. The banknotes that have been successfully identified by the discrimination unit 207 before the generation of rejected banknotes are conveyed to the deposit / withdrawal port 202 and discharged to the customer.
[0040]
The rejected banknote is detected by the banknote state detection unit 211 inside the apparatus, and the banknote conveyance state is detected. Based on the detected information, the skew / shift correction mechanism 209 parallels the banknote from the skewed posture and the normal position. Correct the shifted shift state. Thereafter, the corrected banknote is again discriminated from the denomination by the banknote discrimination unit 207, and the banknote whose amount and denomination are determined is conveyed to the deposit / withdrawal port 202.
[0041]
On the other hand, the banknote state detection part 211 detects the banknote conveyance state again for the banknote whose amount and denomination are indeterminate. The above operation is repeated until the type and number of banknotes are determined. Thereafter, after the re-identification of the reject banknote is completed, the separation operation is resumed, and the normal operation is restored.
[0042]
In the paper sheet number determination device having the above-described configuration, when the generation of the uncertain banknote is detected by the discrimination unit, the separation from the denomination box is stopped, which is the cause of the uncertain banknote determination. Since it re-carrys after correcting the abnormal state of a banknote, the increase in the abnormal state of a conveyance banknote can be suppressed and generation | occurrence | production of the further reject banknote can be prevented.
[0043]
FIG. 7 shows a configuration example of a skew / shift correction mechanism which is a posture correction means according to the present invention. The skew / shift correction mechanism 209 is a part that corrects the state of a bill that is determined indeterminate by the discrimination units 203 and 207. The banknote state correction roller unit 104 includes rollers 101 and 102 connected by the same shaft, and is driven by a motor 104a. The motor 104 a is driven based on information from the sensor 211. The motors 104b and 104c rotate the roller unit 104 about the Z-axis center perpendicular to the transport surface, and move the roller unit 104 up and down in the Z-axis direction. When the banknote skew / shift correction mechanism 209 detects the banknote transport timing by the sensor 211 that detects the transport timing of the banknote disposed in the transport path 210 and the transported state, the motor 104a matches the timing. Is driven and the conveyed banknote is sandwiched between the transport surface and the roller 102.
[0044]
8 to 11 show an example of the operation of the skew / shift correction mechanism described above. In these drawings, (b) shows the flow of the correction operation, and (a) shows the actual operation.
8 shows the first stage of the operation of the skew / shift correction mechanism, FIG. 9 shows the second stage, FIG. 10 shows the third stage, and FIG. 11 shows the fourth stage.
[0045]
As shown in FIG. 8, the skew / shift correction mechanism detects the state of the paper sheet by the sensor 211 when a bill is conveyed to the correction unit, and corrects the state based on the detected conveyance state. First, a banknote is pinched by the roller part 104, and the motor 104a is driven to rotate the rollers 101 and 102 until the roller position comes to the center part of the length in the short side direction of the banknote.
[0046]
Next, as shown in FIG. 9, the skew is corrected by rotating the banknote around the Z axis by the skewed angle while being held between the rollers 101 and 102.
Next, as shown in FIG. 10, the roller unit 104 is moved upward from the conveyance surface, and the roller unit 104 is rotated until the rotation direction of the roller is perpendicular to the conveyance direction. Thereafter, the roller unit 104 is moved downward to pinch the bill, and the motor 104a (not shown) is rotated to drive the roller 104 to move the bill by the shift amount to correct the shift.
[0047]
FIG. 11 shows the next operation, in which the skew / shift correction mechanism moves the roller part upward on the conveyance surface, rotates the roller around the vertical axis until the rotation direction of the roller faces the conveyance direction, moves down and moves the banknote. The paper 104 is clamped and the motor 104a (not shown) is rotated to drive the roller 104, and the banknote whose skew and shift are corrected up to the previous stage is sent out.
[0048]
[Embodiment 2]
FIG. 2 is a schematic configuration diagram of a paper sheet handling apparatus showing a second embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 1 denote the same parts as those in the apparatus in FIG.

In the example of the embodiment shown in FIG. 2, a paper sheet state correcting transport route 313 for processing rejected banknotes is provided separately from the normal banknote processing route, and this paper sheet state correcting transport route. A sensor 312 for detecting a banknote transport timing and a transport state, a bill state correcting mechanism 309, and a sensor 311 for detecting a banknote transport state are provided at 313.
[0049]
Since this paper sheet state correction transport route 313 merges with the paper sheet transport path 210 during normal processing in the subsequent stage, the reject paper money is not used without using the entire normal paper sheet transport path 210. The state can be corrected many times. Therefore, the rejected banknote can be corrected without reducing the efficiency of transporting the banknote in a normal state being transported through the transport path 210.

The banknote stacking unit 408c is driven and driven by a motor 408b. The motor 408b is driven based on information from the sensor 407. The sensor 412 is a sensor that detects the timing at which bills are conveyed. The motor 409b drives the conveyance belt to run, and rotates the belt by the output from the sensor 412. When the reject stacker 408 detects the banknote transport timing by the sensor 407, the motor 408b is driven in accordance with the timing, and the belt accelerating / decelerating is performed so that the banknotes transported one after another do not completely overlap each other. Transport. Thereby, the conveyed banknote is stacked in the belt in a slightly shifted form.
[0054]
FIG.6 (c) has shown the flow of operation | movement in the case of isolate | separating the stacked banknote. When separating the banknotes stacked in the belt, the motor 408b is driven to transport the banknotes, and the timing at which the banknotes are transported is detected by the sensor 412. The motor 409b drives the belt at a higher speed in accordance with the banknote transport position detected by the sensor 412, and sets the banknote transport interval at a predetermined speed while separating the banknotes sent a little ahead one by one at a high speed. The banknotes are separated one after another while keeping the interval.
[0055]
Even if the denomination and number of banknotes cannot be determined by the discriminating unit, the banknotes are temporarily stored in the reject stacker 408 and then separated one by one. The banknotes are re-differentiated in a double-fed state and then passed through a banknote discrimination part or a simple discrimination part that detects the size and thickness of the banknotes. Denomination and number can be determined.
[0056]
Also, by providing such a temporary stacker for rejected banknotes, it becomes possible to correct the state of banknotes when there is room, such as waiting time between transactions rather than during normal processing. Even when this occurs, it is possible to suppress a decrease in processing performance. Further, the reject stacker 408 is provided with a re-separating means, and the rejected banknotes are stacked in a state where they are not completely stacked, separated one by one and conveyed to the state detection mechanism and the posture correcting mechanism, so that the banknotes are double fed. In this state, it is possible to prevent posture correction and re-discrimination, and to improve the type and number of rejected banknotes, thereby improving the efficiency of reject banknote processing.
[0057]
[Embodiment 4]
Next, another embodiment of the paper sheet posture correcting means will be described with reference to FIGS.
12 is a perspective view showing a second example of the skew / shift correction mechanism for paper sheets, FIG. 13 is a perspective view showing the operation of the apparatus shown in FIG. 12, and FIG. 14 is a view of the apparatus shown in FIG. FIG. 15 is a perspective view showing a third example of the skew / shift correction mechanism for paper sheets, and FIG. 16 is an explanatory diagram showing a method for calculating an additional skew angle and a ball rolling distance.
[0058]
In the skew / shift correction mechanism shown in FIG. 12, the sphere 105 is supported by a guide portion 106 having a circular hole. The guide unit 106 is constituted by a radial bearing 106a and three rollers 106b, 106c, 106d, and slides the ball 105 so that the ball 105 can freely rotate. The ball 105 is rotated by driving the roller 107 driven by the motor 107a and the roller 108 driven by the motor 108a (not shown) independently or simultaneously. The rollers 107 and 108 are supported by bearings. The roller 107 is supported so as to rotate about an axis in a direction substantially perpendicular to the bill conveyance surface, and the roller 108 is supported substantially parallel to the conveyance surface.
[0059]
FIG. 13 shows a perspective view of the operation of the skew / shift correction mechanism. When the bill is conveyed to the correction unit, the sensor 211 detects the conveyance timing and conveyance state of the bill, and performs correction based on the information.
[0060]
When the banknote is clamped in accordance with the conveyance timing, the roller 107 is rotated to rotate the banknote by the angle θ (FIG. 13 (1)). The angle θ at this time is obtained by the method shown in FIG. Next, the roller 108 is stopped, the roller 107 is rotated, and the shift is corrected by sending the banknote in the transport direction (FIG. 13 (2)). Then, the roller 107 is stopped and the roller 108 is rotated to rotate the skew amount + θ. To correct the skew (FIG. 13 (3)). Thereafter, the roller 107 is rotated to perform feeding (FIG. 13 (4)).
[0061]
FIG. 14 (a) shows a view of the correction operation as seen from above. In this figure, the rollers 107 and 108 are not shown. FIG. 14B is a view of the operation for correcting the shift and skew in a different procedure from the above-described correction operation as seen from above.
[0062]
FIG. 15 shows another example of the posture correcting mechanism using the spherical surface. Also in this example, the same effect can be obtained in correcting shift / skew. The roller 107 shown in FIG. 15 is mounted so as to rotate in the transport direction, whereas the roller 112 is mounted so as to rotate in a direction perpendicular to the transport direction. The configuration is the same except that the attachment position of the roller 113 is changed accordingly.
[0063]
The mechanism in FIG. 15 corrects skew by sandwiching the banknote and rotating the roller 113 based on the transport timing and banknote transport state information detected by the sensor 211 (FIG. 15 (2)). The shift is corrected by rotating 112 (FIG. 15 (3)). Although not shown here, it also has a transport mechanism for transporting banknotes.
[0064]
FIG. 16 shows how the control amount is determined based on the skew amount and the shift amount detected by the bill state detection mechanism in the mechanism operation of FIG.
In FIG. 16, point B is a point where the skewed / shifted banknote is conveyed and contacts the spherical surface of the correction mechanism for the first time, point A is the middle point of the rear end with respect to the conveyance direction of the length direction of the banknote, C is the midpoint of the front end with respect to the conveying direction of the bill lengthwise direction, the point D is the center of gravity of the bill, and the line segment AC is the centerline of the bill. θ1 is an angle formed by the line segment DC and the conveyance direction, and is an amount representing the skew angle of the bill. θ2 is an angle formed by the line segment AB and the conveyance direction, and is a skew angle that is first added to the bill by the posture correcting mechanism according to the present invention. θ3 is an angle formed by the line segment AB and the line segment AD. X is the projection distance of the line segment BD in the direction perpendicular to the transport direction, and is an amount representing the shift amount of the banknote.
[0065]
In order to correct the shift, the central axis of the bill must come to the position of the sphere. Since the contact point between the sphere and the bill aligns with the central axis of the bill as the sphere rotates in the transport direction, the skew amount of the bill is changed. At this time, in order to shorten the processing time and reduce the load, the amount of skew to be changed must be small.
[0066]
The first additional skew angle θ2 at this time can be obtained from θ3-θ1 from the triangle ACB, and θ3 can be obtained from the length l1 + l2 between CBs.
That is, from the triangle DCE,
l1 = (l4 / 2) tan θ1 (Expression 1)
From the triangle BFE
l2 = X / cos θ1 (Formula 2)
Θ3 is obtained by Equation 3 from Equations 1 and 2 and the triangle ACB.
θ3 = arctan ((l1 + l2) / l4) (Equation 3)
From this, θ2 is obtained by Equation 4.
θ2 = θ3-θ1 (Formula 4)
Further, the rolling distance l3 of the sphere can be obtained from the triangle ACB according to Equation 5.
[0067]
[Expression 1]

[0068]
The actual operation is to correct the shift by skewing the banknote by θ2 and rotating the ball by l3, and further correcting the skew by correcting skew by θ3.
