Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet feeding device which is internally constructed in a transaction processing device for handling paper sheets such as banknotes, and more particularly, to completely avoid abnormal banknotes unsuitable for feeding. The present invention relates to a paper sheet feeding device and a transaction processing device having high feeding performance.

[0002]

2. Description of the Related Art Generally, a paper sheet feeding device of this type is
As shown in FIG. 8, a pressing plate 83 is arranged above the paper sheet stacking unit 82 in which the paper sheets 81 are stacked in the vertical direction, and the pressing plate 83 is pressed downward and urged downward. A pickup roller 84 that is in contact with the lower surface of the paper sheet 81 and operates to feed the paper sheets one by one is disposed below the urged paper sheet 81. The feed roller 85 and the gate roller 86 are arranged, and the rollers 84 to 86 are fed out to operate the paper 81.
Are delivered one by one.

At this time, a photoelectric detection sensor provided at the feeding portion detects whether the fed paper sheet is in a proper feeding state or an unsuitable feeding state, and a skew is generated, a state where the sheet is ejected from the stacking portion, or a paper sheet is fed. The presence / absence of a feeding abnormality such as a half-folded state of leaves is detected.

However, with such a detection structure alone, it is not possible to detect an abnormality such as a fold, wrinkle, or water wetting of the paper sheet itself, and it is unclear whether or not the paper sheet is fed out until the paper sheet is fed out and photoelectrically detected. Therefore, the detection when a feeding abnormality occurred was delayed, and the subsequent measures could not be taken promptly.

Further, as shown in FIG. 9, in order to prevent the occurrence of a jam in the subsequent stage due to the paper sheet having the feeding abnormality, the feeding abnormality paper sheet 9 is detected at the time when the feeding abnormality is detected.
There is known a sheet feeding device 92 having a pullback function for pulling back 1 to the original position. However, in this case, when the paper sheets are pulled back, as shown in FIG. 10, if the stacking load in the paper sheet stacking unit 93 is high, the pull-back resistance of the abnormal feeding paper sheet 91 becomes high and the buckling deformation occurs. Inducing 94, the paper sheet accumulating portion 93
Will cause a paper jam (jam). It is also conceivable that the abnormally-delivered paper sheets are directly guided to the return path in the forward feed direction and conveyed, but in this case, because of the abnormally-delivered paper sheets, it is easy to cause a jam in the conveying process and the feeding performance is stable. Tended to be poor in sex and reliability.

[0006]

This is particularly problematic in the area where the user directly operates the paper sheets. For example, in a banknote deposit port of an automatic teller machine (ATM), banknotes in various states including abnormal banknotes that are unsuitable for payout, or something other than banknotes may be inserted. Please do not insert anything other than '' or `` Please extend the banknote well '' and it is not possible to completely eliminate the insertion of abnormal banknotes from the banknote slot, and it looks It is conceivable that even a banknote that is not abnormal will become an abnormal banknote while repeating the mechanical operation until shifting to the feeding operation.

In view of the above, the present invention detects the abnormal element for feeding the paper sheet not only at the time of feeding the paper sheet, but also from before the sheet is stored in the paper sheet storing section, and also for detecting the paper sheet. An object of the present invention is to provide a paper sheet feeding device and a transaction processing device capable of ensuring a pull-back space inside the paper sheet storage portion and performing stable pull-back at the time of pulling back.

[0008]

According to the first aspect of the present invention,
A paper sheet feeding device comprising a paper sheet feeding means for feeding paper sheets one by one from a paper sheet storage portion in which a plurality of paper sheets are stored in a stacked manner, the paper sheet feeding means The paper sheet monitoring means for detecting the presence or absence of an abnormal feeding element of the paper sheet fed out from the paper sheet, and the paper sheet fed out by the paper sheet feeding means are fed back to the original paper sheet storage section. And a control means for driving the paper sheet withdrawing means and the paper sheet withdrawing means when the paper sheet monitoring means detects a paper sheet feeding abnormal element at the time of feeding the paper sheet. To do.

According to a second aspect of the present invention, the paper sheet monitoring means is used as at least one of the feeding torque detection sensor, the running state detection sensor, the thickness detection sensor, the reflection type detection sensor and the water content detection sensor. It is characterized by

The invention according to claim 3 is characterized in that the paper sheet storage section is provided with a retracting means for temporarily retracting the stored paper sheet from the feeding portion.

According to a fourth aspect of the present invention, there is provided a transaction processing device which is equipped with a paper sheet feeding device and performs transaction processing of paper sheets.

[0012]

According to the present invention, when the paper sheet is delivered from the paper sheet storage section, the paper sheet is delivered based on the delivery operation of the paper sheet delivery means. At this time, when the paper sheet monitoring means detects a paper sheet feeding abnormal element, the control means drives the paper sheet pulling back means to feed back the paper sheet fed out by the paper sheet feeding means and return the original. Pull it back to the paper sheet storage section.

Further, the paper sheet monitoring means may include one or a plurality of detection sensors of a feeding torque detection sensor, a running state detection sensor, a thickness detection sensor, a reflection type detection sensor or a water content detection sensor. In addition, the abnormal elements for feeding out the paper sheets are monitored.

Further, the paper sheet storage portion is provided with a retracting means for temporarily retracting the stored paper sheet from the feeding portion of the paper sheet storage portion, and the paper in the paper sheet storage portion is retracted when the paper sheet is pulled back. Retract the leaf so that it does not collide with the pullback paper sheet.

Further, a transaction processing apparatus is provided with a paper sheet feeding device having such a paper sheet return processing performance to perform transaction processing of paper sheets.

[0016]

As a result, the presence or absence of the abnormal feeding element of the paper sheet is continuously detected from the feeding standby state to the feeding operation. Therefore, it is possible to detect not only the feeding state, but also the folding, wrinkling, and the degree of water wetting of the paper sheet itself, and it is possible to detect an abnormality early by detecting an abnormal feeding element of the paper sheet before feeding, and immediately. Optimal treatment can be taken.

For example, when it is detected that a jam may be induced, the paper sheet before the feeding operation is not fed out, and during the feeding operation, the paper sheet is immediately returned to the original position. To process. At this time, the paper sheets in the paper sheet storage section are retracted in conjunction with the pullback operation to secure a pullback space at the original storage position and pull back, so that the paper sheets to be pulled back have a large contact resistance. It can be pulled back stably without receiving, and it is possible to reliably prevent a jam at the time of pulling back. Further, if there is no abnormality in the paper quality of the pulled back paper sheet, the paper sheet can be re-delivered.

Further, in the case of monitoring the paper sheets, when the feeding torque detection sensor is used, it is possible to detect the occurrence of jam and the degree of slippage from the torque applied to the feeding system roller, and when the running state detection sensor is used, the paper is detected. The skew generation and the degree of rattling can be detected from the left and right movements of the leaves, and if a thickness detection sensor is used, the occurrence of continuous feeding or emptying can be detected from the thickness of the paper sheet, and a reflection type detection sensor is used. If
The degree of skew can be detected from the detection position of the edge of the paper sheet, and if a water content detection sensor is used, the degree of jam occurrence can be detected from the water content of the paper sheet, and the data of such a detection sensor can be analyzed. If the detection data deviates from the reference value, it can be determined that there is a sheet feeding abnormal element, and appropriate processing can be immediately performed. Furthermore, if you detect not only one sensor but also multiple sensors,
More reliable detection data can be obtained. Furthermore, when the paper sheet delivery device is internally configured in the transaction processing device, the paper sheet delivery performance is stable and highly reliable paper sheet transaction processing can be performed.

It is equipped with a detection function that detects multiple points.

First, the feeding torque detecting sensor S1 is directly connected to the feed roller 16 and detects the fluctuation of the torque applied to the feed roller 16, and if the sheet is fed normally, one sheet is fed between the feed roller 16 and the gate roller 17. Only the banknotes of the above can be passed and the torque applied to the roller is small. On the other hand, when a plurality of bills are caught or even one folded bill enters between the rollers 16 and 17, the torque value applied to the rollers increases, and when this torque value exceeds a certain value, an abnormality occurs. To output an error. In this case, if the differential value of the torque change is further captured, it is possible to predict a bill feeding abnormality from the value of the torque change and detect the bill early.

The traveling state detection sensor S2 is used in the banknote stacking unit 13
A pair of left and right independently installed on the bottom surface of the paper, the traveling detection rollers 18 that individually contact and rotate at the left and right positions of the banknote 12 that is fed in a horizontally long state, and the respective conductive belts 19 on these rollers.
It is composed of both rotary encoders 20 through which power is transmitted via, and the output signals of the rotary encoders 20 on both sides are monitored to detect real-time skews and rattling at the time of paying out bills.

The thickness detecting sensor S3 is a feed roller 16
And the gate roller 17 are provided downstream of the rollers 16,
The bill 12 immediately after being fed out from between 17 is sandwiched by a pair of upper and lower detection rollers 21, and the thickness of one bill is taken out,
Detects by distinguishing from abnormal thickness such as bill folds and multiple sheets.

The reflection type detection sensor S4 is independently installed in a pair of left and right on the rear end side of the bottom surface of the banknote stacking unit 13, and detects reflected light reflected on both sides to thereby fluctuate both sides of the banknote fed in a horizontally long state. It detects by tracking the condition separately,
The skew of the bill to be fed out and a feeding abnormality such as rattling are detected. Further, when the payback operation is performed on the bill that is being fed out, the payback bill can be confirmed.

The water content detection sensor S5 is installed in the central portion of the bottom surface of the banknote stacking unit 13, and measures the water content of the bottom position banknote to be fed next to detect the propriety of feeding.

When any one or a plurality of the above-mentioned detection sensors S1 to S5 detect a bill feeding abnormal element, the bill feeding unit 1 does not start feeding before the bill feeding, and the bill stacking unit 1
3 is made to stand by to prevent the occurrence of feeding failure. If it is in the middle of feeding, the bill in the middle of feeding is pulled back and stored in the original position.

FIG. 3 shows a bill withdrawing mechanism 22, which is provided with a handling 23 for holding the stacked bills and retracting them upward, and a stacked bill detection sensor S6.
The handling 23 is provided with a holding device (not shown) that holds a plurality of banknotes together in a vertical direction and a lifting device 24 that moves up and down. Then, at the time of pulling back the bills, after the presence or absence of the bills 12 accumulated in the bill accumulating unit 13 is detected and confirmed by the accumulated bill detecting sensor S6, the handling 2
A large number of banknotes 12 stacked in the banknote stacking unit 13 in 3
Hold the ... and move it upward. As a result, a withdrawal space 25 is formed at the bottom of the banknote stacking unit 13, the withdrawal space 25 is secured at the original position where the banknotes were stacked, and the banknotes to be withdrawn are stably withdrawn without receiving a large contact resistance. Be done.

FIG. 4 shows a block diagram of a control circuit of the bill feeding device 11, in which the CPU 41 controls each circuit device in accordance with a program stored in the ROM 42, and the control data is readablely stored in the RAM 43. Furthermore, CPU
41 is based on the detection signals of the respective detection sensors S1 to S6,
The drive motors M1 to M5, which will be described later, are drive-controlled.

The pressing plate drive motor M1 moves the pressing plate 14 downward to press it when increasing the feeding pressure of the accumulated bills, and moves it upward to avoid the accumulation pressure.

The transport drive motor M2 drives the main transport path connected to the banknote stacking unit 13 to deliver the dispensed banknotes 12
The sheets are sandwiched and conveyed one by one to the conveyance target position.

The pickup roller drive motor M3 activates the pickup roller 15 at the start of feeding the bill,
The banknotes stacked in the banknote stacking unit 13 are fed out one by one from the bottom surface. Further, when the banknote is pulled back, the banknote in the middle of being fed out is pulled back to the original position by driving in reverse rotation.

The feed roller driving motor M4 activates the feed roller 16 to feed out the bill, which has been started to be fed out, between the gate roller 17 and the feeding roller 16, and feeds it out to the main transport path in the subsequent stage. When the bill is pulled back, the feed roller 16 is driven in the reverse direction to pull back the bill being fed out to the original position.

The bill return mechanism drive motor M5 causes the handling 23 to clamp and raise and lower the bills, and when pulling back the bills, the plurality of bills 12 ... Collected in the bill stacking unit 13 are collectively retreated upward. Let

The bill feeding device 11 thus constructed
The feeding processing operation will be described with reference to the flowcharts of FIGS. Now, when an ATM deposit transaction, a customer inserts a plurality of bills into a bill deposit port (step n1
), The inserted banknotes have a water content detection sensor S5.
Detects the water content of the bill itself at the feeding position, and if a large amount of water such as water wetting that induces feeding abnormality is detected at this time, it may cause a jam in the subsequent stage (step n2). The CPU 41 resets the deposit acceptance operation, collectively returns the inserted banknotes, removes the abnormal banknotes from the returned banknotes, and then re-inserts them.
The display is guided by the TM display (steps n3 to n5).

When the customer re-inserts the deposited banknote in accordance with this re-insertion guide, the CPU 41 restarts the deposit transaction. On the other hand, if the transaction is stopped, the deposit transaction ends (step n6).

If the water content detection sensor S5 does not detect an abnormal water content, the pickup roller 15 and the feed roller 16 are driven to take out one bill (steps n7 to n8).

At this time, the running state detection sensor S2 detects the skewed state on the left and right sides of the bill 12 fed in the horizontally long state and the feeding state such as rattling, and the feeding torque detection sensor S1 detects the torque value applied to the feed roller 16. The presence / absence of a plurality of banknotes or banknote folds is detected, and an abnormal thickness such as banknote folds or multiple banknotes is detected by the thickness detection sensor S3 (steps n9 to n11).

At this time, even one of the detection sensors S1 to S3
If it detects an abnormality, the CPU 41 immediately stops driving the pickup roller 15 and the feed roller 16 and performs a pullback operation. In this case, the banknote stacking sensor S6 detects and confirms whether or not the banknotes remain in the banknote stacking unit 13, and if there is no banknote, the banknote stacking unit 13 is empty, and the banknote stacking unit 13 continues the pullback operation. On the other hand, if it remains, the bill withdrawal mechanism 22 is driven to perform the withdrawal operation (step n).
12-n14).

At the time of this withdrawal, the CPU 41 drives the banknote withdrawal mechanism 22 to move the banknotes remaining in the banknote stacking unit 13 upward and collectively, and forms a withdrawal space 25 under the banknote stacking unit 13. Then, the pickup roller 15 and the feed roller 16 are reversely rotated to pull back the abnormal bill. At this time, the banknotes are smoothly withdrawn by the withdrawal space 25 secured in the banknote stacking unit 13 (steps n15 to n17).

When the reflection type detection sensor S4 detects and confirms that the abnormal feeding bill has been returned to the original position, the re-feeding operation is tried, and if the feeding is still impossible, the feeding operation is stopped (steps n18 to n19). ).

On the other hand, if it is a normal payout, the payed-out bill is guided to the main transport path in the subsequent stage, and the payout process of the bill is completed. In this way, the predetermined number of banknotes are continuously fed out (steps n20 to n21).

FIG. 7 shows a bill withdrawing mechanism 71 according to another embodiment of the present invention, which comprises an upper handling 72, a lower handling 73, and an integrated bill detecting sensor S7.

The upper handling 72 is provided above the bill feeding position, and is provided with an upper lever L1 of a V-shape connected to a lifting device 74 to allow it to move up and down. When the bill is pulled back, the lower end portion of the upper lever L1 is fed to the bill. The lower back edge of the stacked banknotes 76a stacked in the stacking unit 75 is opposed, and the lower edge of the front end of the stacked banknotes 76a is moved upward so as to be pulled back downward to the front end side of the stacked banknotes 76a. 77 is formed. By ensuring the pull-back space 77, the fed-out bills 76b can be pulled back smoothly.

The lower handling 73 is disposed below the bill feeding position, and the base end of the lower lever L2 having the fulcrum pin 78 in the middle as a tilting fulcrum is connected to the solenoid 79 so that the solenoid 79 is turned on / off. Based on the operation, the tip of the lower lever L2 moves in an arc shape along the horizontal pullback direction, and accordingly, the pullback bill 76b is moved from the lower surface side in the pullback direction.

In this case, as a pullback procedure, first, when the accumulated bill detecting sensor S7 detects that the accumulated bills 76a are accumulated in the bill accumulating portion 75, the upper handling 72 is driven to drive the bill accumulating portion 75. A pull-back space 77 is secured in the lower part of the sheet, and then the feed roller 80 is reversely driven to pull back the bills being fed. By this pullback operation, the bill is pulled back to the state where the leading end portion on the payout side has popped out. Then, finally, the lower handling 73 is driven to execute the two-stage pullback operation of completely pulling back the pulled-back bill 76b to the original position. As a result, the retracted banknote 76b can be reliably returned to the banknote stacking unit 75.

Therefore, if such a pullback space 77 can be formed, various bill pullback mechanisms can be constructed. Further, although the above-mentioned upper lever L1 has been shown as being lifted from the front in the lateral direction of the bill, the present invention is not limited to this, and the upper lever L1 may be lifted from both left and right sides in the lateral direction.

As described above, since the bill feeding abnormality element is detected from the feeding standby state to the feeding operation, the bill feeding abnormality element is detected all the time. Therefore, not only the feeding state is appropriate but also the bill itself is folded. It is possible to detect defects such as wrinkles and water wetting, and to detect abnormalities at an early stage by detecting an abnormal feeding element of the bill itself during standby for feeding, so that an optimum measure can be taken. For example, when it is detected that a jam may be induced, the feeding operation is not performed, and during the feeding operation, the bill is immediately returned to the original position.

Further, when the bill is monitored, when the feeding torque detection sensor is used, the occurrence of a jam or the degree of slippage can be detected from the torque applied to the feeding system roller, and when the running state detection sensor is used, the left and right of the bill are detected. It is possible to detect the occurrence of skew and the degree of rattling from the movement of the bill, and if the thickness detection sensor is used, it is possible to detect the occurrence of continuous feeding or emptying from the thickness of the bill, and if the reflection type detection sensor is used, the bill end The degree of skew can be detected from the detection position of the section, and when a water content detection sensor is used, the degree of jam occurrence can be detected from the water content of the bill. When the data of such a detection sensor is analyzed and the detection data deviates from the reference value, it can be determined that there is a bill feeding abnormal element, and appropriate processing can be immediately performed. Furthermore, more reliable detection data can be obtained by detecting not only one sensor but a plurality of sensors in combination. Further, when the bill feeding device is internally configured in the ATM, the bill feeding performance is stable, and highly reliable bill transaction processing can be performed.
