Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an automatic transaction device that accumulates conveyed paper sheets in a stacked state.

[Technical background of the invention and its problems] Devices that perform processing such as counting paper sheets at high speed (for example, 10 sheets/second) For example, in banknote processing devices used in banks, deposited banknotes are stored in a safe. In order to do this, it is necessary to stack and accumulate the bills for each transaction, or to accumulate the bills to be withdrawn at the payment slot.

In such a banknote processing device, there is no problem when stacking a small number of banknotes, but when stacking a large number of banknotes, the distance between the banknotes that have already been stacked and the next banknote to be stacked may be large. As the stacking progresses, the number decreases, and there is a possibility that the trailing edge of the already stacked banknotes collides with the leading edge of the banknote to be stacked next, resulting in stacking failure. To solve this problem, for example, an accumulation method using an impeller has been proposed, but this method has disadvantages such as an increase in the size of the device and an increase in cost.

[Purpose of the invention] The present invention has been made in view of the above circumstances, and has a simple configuration that can achieve miniaturization and cost reduction of the device, and can also be used even when a large number of paper sheets are accumulated. The object of the present invention is to provide a highly reliable automatic transaction device that does not cause stacking defects.

[Summary of the invention] This invention is an automatic system that transports multiple banknotes that have been input in bulk one by one through a receiving and transporting path, distinguishes whether the transported banknotes are genuine or fake, and performs a deposit transaction. In the transaction device, a discriminating means for discriminating genuine, counterfeit, and denomination of deposited banknotes, a conveying means for conveying the banknotes determined to be genuine by the discriminating means, and a counterfeit bill conveying means for conveying the banknotes determined to be counterfeit. and a control means for driving and controlling each of the conveying means, and the counterfeit bill conveying means has first and second detecting means arranged at intervals in front and rear stages in the conveying direction, respectively, and a control means for driving and controlling each of the conveying means. 1
an intermittent conveyance means that collects and conveys a counterfeit bill while holding the counterfeit bill and sequentially shifting its leading edge each time a counterfeit bill is detected by the detection means;
When the leading edge of the accumulated and conveyed counterfeit notes is detected by the second detection means, the conveyance operation is stopped, and the banknotes held by the counterfeit note conveyance means are transferred to a path different from the taking-in conveyance path. This feature is characterized by controlling the return to the return transport section.

In addition to the function of taking out the inserted banknotes as described above, this accommodating section 15 also has the function of taking out the inserted banknotes.
It also has the function of accumulating rejected banknotes or paid banknotes sent out and conveyed via 1b. In this sense, 21b is also referred to as a return transport section. For this purpose, the writing table 105 is designed to rotate in the direction A shown in FIG. 4a. That is, when taking banknotes into the apparatus and conveying them, the mounting table is positioned in the state shown in FIG. Furthermore, when stacking banknotes sent out from the second stacking and transporting section 21b, the mounting table 105 is rotated counterclockwise from the state shown in FIG. 4a.

The drive mechanism of this mounting table 105 is shown in FIG. 5b. In FIG. 5b, the mounting table 105 is the side plate 1.

Next, the details of the banknote conveyance system are shown in Figure 4 a, b,
This will be explained with reference to c. The main driving source of this banknote conveyance system is a banknote conveyance system drive motor 101.
This conveyance system driving motor 101 drives the conveyor belts other than the first and second collecting conveyance sections 21a and 21b so that their circumferential speeds are equal.

Further, this transport system driving motor 101 is connected to the take-out roller 104 and the feed roller 1.
It also drives the rotation of 03. That is, the take-out roller 104 and the feed-out roller 103 are configured to receive the driving force of the transport system driving motor 101 via the electromagnetic clutch 102.
When the electromagnetic clutch 102 is turned on, the take-out roller 104 and the feed-out roller 103 are rotated in synchronism to take in and convey the banknotes placed on the placement table 105 one by one. When a sensor (not shown) detects that no banknotes are present on the mounting table 105, the electromagnetic clutch 102 is turned off and the take-out roller 10
4. The drive of the feeding roller 103 is stopped.

Next, the first and second accumulation conveyance sections 21a, 2
1b will be explained. Said first accumulation conveyance section 2
1a is a first banknote conveyance belt 114 provided between the branch conveyance path 22l and the intake conveyance path 22a, and one end side (the latter stage in the conveyance direction) is in contact with the first banknote conveyance belt 114. The other end (front stage in the conveyance direction) is constituted by a second banknote conveyance belt 115 that is stretched so as to be able to come into contact with and separate from the branch conveyance path 22l. Further, the front part of the second banknote conveyance belt 115 in the conveyance direction is always spaced apart from the branch conveyance path 22l, and A wedge shape is formed so that the distance between them becomes narrower.

A rotary lever 150 is attached to the roller 152 at the front stage of the second banknote conveyance belt 115 in the conveyance direction, and is rotatable in the direction D in FIG. 4A around the fulcrum 151. An iron core 118a, which is inserted and removed by energizing the first continuous conveyance solenoid 118, is locked in the intermediate portion of the rotating lever 150. Further, a first gear 153 is fixed to the roller shaft of the roller 152.
A second gear 154 that is continuously rotated by the drive of the transport system drive motor 101 is disposed at a position facing away from the gear 153 . and,
When the first continuous conveyance solenoid 118 is energized, the second banknote conveyance belt 115 and the branch conveyance path 22l come into contact with each other due to the action of the rotary lever 150, and the first and second gears 153 and 154 mesh with each other. I will do it. Therefore, when the first continuous conveyance solenoid 118 is energized, the second banknote conveyance belt 115 continuously rotates to convey banknotes.

On the other hand, on the latter side of the second banknote conveyance belt 115 in the conveyance direction, as shown in FIGS. A roller 112B is provided that is rotatably supported by the drive shaft 156 and stretches a third banknote conveyance belt 157 that forms a part of the take-in conveyance path 22a. The drive shaft 156 is configured to receive the rotational driving force of an intermittent conveyance drive motor (for example, a pulse motor) 109 via a one-way clutch 110 and a drive transmission belt 155.

When the presence of a banknote is detected by a first banknote detection sensor 141 (described later), the intermittent conveyance drive motor 109 adjusts the length of the banknote (the length along the conveyance direction) based on the drive control of the control unit 90. It is designed to be driven by the number of pulses corresponding to a distance shorter than that of 5 mm to 10 mm, for example. Therefore, by repeating the intermittent drive of the intermittent conveyance driving motor 109, the banknotes continuously conveyed via the branched conveyance path 22l are transferred between the first and second banknote conveyance belts 114 and 115. In this case, the bills are sandwiched and conveyed in a stacked state with their conveying tips shifted. In this case, the first collecting and transporting section 21a serves as an intermittent transporting means, and since it is intermittently driven according to the difference in rejected tickets, this intermittent drive allows the rejected tickets to be stacked while being shifted. It functions as a means.

Note that the one-way clutch 110 is configured so that the second banknote conveying belt 115 is connected to the first and second gears 15.
3 and 154 to prevent the rotational force of the drive shaft 156, which rotates when being continuously rotated, from being transmitted to the intermittent conveyance drive motor 109. In addition, first and second banknote detection sensors 141 and 142 are respectively arranged at the front stage and rear stage in the transport direction of the first accumulation and transport section 21a. The first and second banknote detection sensors 141 and 142 are light emitting elements 141a and 142.
a and light receiving elements 141b and 142b, and detects the presence of banknotes. The first banknote detection sensor 141 disposed upstream of the first stacking and transporting section 21a is used to control the drive of the intermittent transport drive motor 109, as described above.

On the other hand, the second banknote detection sensor 142 detects that the conveyance tip of the stacked banknotes that are intermittently conveyed while being held between the first and second banknote conveyance belts 114 and 115 is near the exit of the first accumulation and conveyance section 21a. When this is detected, the control unit 90 stops driving the entire device.
This is to prevent the banknotes sent out from the first collecting and transporting section 21a from being led to the receiving and transporting path 22a, which continues to be continuously transported, and being taken and transported again along the same route as the deposited banknotes. .

Next, the second collecting and transporting section 21b will be explained. The second stacking and conveying section 21b is disposed at a later stage in the conveyance direction of the banknote sending conveyance path 22m, and is configured to guide rejected banknotes or disbursed banknotes to the storage section 15. Second accumulation conveyance section 21
As shown in FIG. 4a, b is an endless belt that is arranged so as to be able to come into contact with and separate from the fourth banknote conveyance belt 160 with its front side in the conveyance direction in contact with the banknote delivery conveyance path 2m. It consists of a fifth banknote conveyance belt 161. In addition, the fifth banknote conveyance belt 161
The front side in the conveying direction is always spaced apart from the fourth banknote conveying belt 160, and the fourth,
The fifth bill conveyance belts 160, 161 are wedge-shaped so that the distance between them becomes narrower along the conveyance direction. The fifth bill conveyance belt 161 is rotatable in the direction E shown in FIG.
Similarly to a, the second continuous conveyance solenoid 119
This is done by rotating the rotating lever 162 by energizing the lever.

Furthermore, although not shown, when the fifth banknote conveyance belt 161 is rotated in the direction E in the figure and comes into contact with the fourth banknote conveyance belt 160, the fifth banknote conveyance belt 161
A gear for continuously transporting the banknote transport belt 161 meshes with a gear driven by the transport system drive motor 101.

Further, the driving roller 113 is connected to the intermittent conveyance driving motor 1 via a one-way clutch 111.
Rotational power from 09 is transmitted. Therefore, like the first stacking and transporting section 21a, the second stacking and transporting section 21b is capable of continuous transport of banknotes and intermittent transport of stacking banknotes while shifting the leading end of the banknotes. Note that the roller disposed opposite to the driving roller 113 with the fifth banknote conveyance belt 161 interposed therebetween is an idle roller 117. In addition, this second accumulation conveyance section 2
The third banknote detection sensor 143 disposed on the front side in the conveyance direction of 1b detects the tip of the dispensing banknote using a light emitting element 143a and a light receiving element 143b, and when this detection occurs, the control unit 90 controls the third banknote detection sensor 143. Based on drive control, the drive roller 113 is driven by the number of pulses corresponding to a distance shorter than the length of the banknote.

On the other hand, the fourth banknote detection sensor 144 arranged on the latter side of the second stacking and transporting section 21b in the transporting direction is
The light emitting element 144a and the light receiving element 144b detect the rear end of the rejected banknote or the disbursed banknote, and after this detection, the control unit 90 controls the transport system drive motor 1.

The delivery conveyance path 22m and the second accumulation conveyance section 2
1b is provided with a slip sending port 170 for sending out a payment recording paper (hereinafter referred to as a slip) issued by the card/passbook processing unit 10 (details will be described later) based on the disbursed banknotes. There is. This slip is sent out from the slip sending port 170 via a payment recording paper conveyance means (details will be described later) after the last paid bill passes through the third bill detection sensor 143. In the second stacking and transporting section 21b, the bills are stacked together with the dispensing banknotes with the transporting tip shifted, and sent to the storage section 15.

Details of the deposit processing, deposit rejection ticket processing, and withdrawal bill processing of the bill processing unit 9 configured as described above will be explained with reference to FIGS. 6a to 6c.

First, the banknote deposit processing will be explained. When the banknote deposit mode is selected, the banknote entry/exit door motor 124 is driven based on the drive control of the control unit 90, and the banknote entry/exit door 123 is opened by the action of the banknote door opening/closing mechanism 120. Further, the control unit 90
The mounting table driving motor 140 and the pressing plate driving motor 132 are driven to drive the mounting table 105 and the pressing plate 107.
is set to the state shown in FIG. 4a.

Thereafter, the operator inserts the banknotes in a stacked state at once through the banknote inlet/outlet 4. Then, the banknotes remain in the stacked state between the above-mentioned placing table 105 and the pressing plate 10.
7. Note that at this time, the banknote is not pressed by the pressing plate 107.

Thereafter, the banknote entry/exit door motor 124 is driven to rotate in reverse, and the banknote door opening/closing mechanism 120 causes the banknote entry/exit door 123 to close the banknote entrance/exit 4 . At this time, the plate-like member 127 moves along the plate-like cam 129 in conjunction with the closing movement of the banknote entry/exit door 123, and along the curved part of the plate-like cam 129 when the banknote entry/exit door 123 is closed. The banknote stopper 12 rotates due to the biasing force of the coil spring 128.
6 is projected as shown in FIG. 5a. This bill stopper 126 is connected to the above-mentioned placing table 105 and the pressing plate 1.
The banknotes are aligned by coming into contact with the end faces of the stacked banknotes interposed between the banknotes 07 and 07.

After this, the control unit 90 controls the pressing surface driving solenoid 135 to be energized to rotate the pressing surface 107a in the direction B shown in FIG. 4a or FIG.
Press the stacked banknotes against 04. At this time, since an elastic member 180 with a reduced surface friction coefficient is attached to the banknote contacting surface of the pressing plate 107a, the pressing force applied to the entire surface of the banknote is reduced by the elasticity of the elastic member 180. Equalized.

After that, the control unit 90 controls the transport system drive motor 1.
01 to drive the conveyance system of the banknote processing unit 9. Then, the take-out roller 10
4 and a feeding roller 103 arranged ahead of it.
The rotational driving force of the conveyance driving motor 101 is inputted to the conveyance driving motor 101 via the electromagnetic clutch 102, and both are rotated in synchronization. At this time, the banknotes frictionally delivered by the take-out roller 104 are transferred to the elastic member 18.
Since the pressing force is equalized by 0,
The banknotes are not transported in a skewed state, and it is possible to eliminate paper jams or unreadability in the inspection section 20 that would occur due to the banknotes being transported in a skewed state. The banknotes taken out by the take-out roller 104 are transferred to the pay-out roller 103
and the first number-of-bills regulating roller 106 prevent two-bill feeding, and one bill at a time is sent to the other side one by one.

The banknotes taken in and conveyed in this manner are transferred to the inspection section 20 according to the flow shown in FIG. 3b as described above.
Each banknote storage section 16, 17, according to the inspection result at
They are divided into 18 and accumulated. In addition, inspection department 2
As shown in FIG. 3c, the bills that are identified as counterfeit by the number 0 are sorted by the sorting gate 23a to the branch conveyance path 22l, and transferred to the first accumulation conveyance section 21a.
will be accumulated in.

Here, details of the processing of banknotes that are identified as counterfeit banknotes will be explained with reference to FIGS. 6a, b, and c. The banknotes conveyed through the branch conveyance path 22l are stacked on the first accumulation conveyance path 21a in the following manner. That is, the tip of the banknote conveyed along the branch conveyance path 22l is the first banknote detection sensor 141.
When the control unit 90 interrupts the intermittent conveyance drive motor 1
09 to rotate the intermittent conveyance driving motor 109 by the number of pulses corresponding to a distance shorter than the length of the banknote, for example, 5 mm to 10 mm. In addition, since the first continuous conveyance solenoid 118 is not operated at this time, the branch conveyance path 22l and the second banknote conveyance belt 115 remain wedge-shaped so that the distance between them narrows in the conveyance direction. be.
Then, by rotating the intermittent conveyance drive motor 109 by a predetermined amount, the banknote is stopped with the leading end of the first banknote being held between the first and second banknote conveyance belts 114 and 115. The first bill detection sensor 14 detects rejected bills, such as counterfeit bills, which sequentially generate this operation.
Repeat every time 1 is interrupted.

Then, these banknotes are transferred to the first and second banknote conveyor belts 11, as shown by the dashed line in FIG. 6a.
4, 115 and is conveyed intermittently. In addition, the first and second banknote conveyance belts 11
The banknotes held between the banknotes 4 and 115 are stacked as shown in FIG. 6b. That is, by intermittently driving the intermittent conveyance driving motor 109 by a predetermined amount, the bills are stacked with their conveying tips shifted.

In this way, while continuing the deposit processing, if a counterfeit bill occurs, the first accumulating and conveying section 2
Counterfeit bills can be accumulated and held in 1a.

Furthermore, since the bills can be stacked while being held between the bill conveyance belts, there is no need for a complicated structure that would lead to an increase in the size of devices such as impellers. On the other hand, if a large number of counterfeit bills are generated during the deposit process, when the number of counterfeit bills reaches a predetermined amount, the first accumulating and conveying section 21
The first banknote accumulated at point a blocks the second banknote detection sensor 142. In this case, the control unit 10 stops driving the entire device. This is because, as described above, the banknotes sent out from the first collecting and transporting section 21a are guided to the receiving transport path 22a, which is the depositing route where they are continuously transported, and are again taken and transported along the same route as the deposited banknotes. This is to prevent banknotes from being counted incorrectly. After stopping the drive of the device, the operator is notified of this by, for example, an alarm.

At this time, the operator opens the banknote entry/exit door 123 to remove the banknotes on the mounting table 105, and continues processing the banknotes that are on the deposit route. Thereafter, the operator selects the counterfeit bill processing mode and performs the following processing. That is, based on the operation control of the control unit 90, the first and second continuous conveyance solenoids 11
8,119 is energized, and the second banknote conveyance belt 11
5 is rotated in the direction D shown in FIG. 4a, and the fifth bill conveyance belt 161 is rotated in the direction E shown in FIG. 4a to form the conveyance system shown in FIG. 6c. At this time,
By the rotation of the second and fifth banknote conveyance belts 115 and 161, the first and second stacking and conveying parts 21a and 21
In b, the continuous conveyance mode is set by the gear meshed with the gear driven by the conveyance system drive motor 101.

When the transport system drive motor 101 is driven in this state, the banknotes stacked in the first stacking and transporting section 21a with their transport tips shifted are held between the first and second banknote transport belts 114 and 115 as they are. It is continuously conveyed and sent out to the intake conveyance path 22a, branched by a distribution gate 23f, guided to the discharge conveyance path 22m, and further transferred to the second accumulation conveyance section 21.
b, and is continuously conveyed and delivered to the storage section 15. (See Figure 6c).

On the other hand, at this time, in the storage section 15, the mounting table driving motor 140 is driven based on the operation control of the control section 90, so as to isolate the mounting table 105 from the take-out roller 104 as shown in FIG. 6c. The banknotes are rotated to a state in which bills sent from the second stacking and conveying section 21b can be accepted. Further, the control unit 90 drives and controls the press plate driving motor 132 to move the press plate 107 upward along the direction C shown in FIG. The pressing surface 107a is rotated counterclockwise to return (see FIG. 6c).

In this way, the accommodating section 15 can receive banknotes from the second collecting and transporting section 21b.
Further, when the banknote entry/exit door 123 is closed, the banknote stopper 126 protrudes across the table 105. Therefore, the banknotes that are continuously conveyed in a stacked state with the conveyance tip shifted from the second accumulation and conveyance section 21b are placed on the placing table 105 in a state in which the end faces of the banknotes are brought into contact with the banknote stopper 126 one after another and aligned. It will be accumulated on top.

After all the counterfeit bills are accumulated on the mounting table 105, the bill entry/exit door 123 is opened based on the detection by the fourth bill detection sensor 144, and the stacked counterfeit bills can be taken out. Note that the process for removing counterfeit bills is not limited to the above-described embodiment; for example, the counterfeit bills accumulated in the first stacking and conveying section 21a are taken out in the same manner as described above.
The banknotes are guided to the first accumulation/conveyance section 21b, where they are temporarily held, and the remaining deposit processing is performed again, and the counterfeit bills generated at this stage are accumulated in the first accumulation/conveyance section 21a. After all the deposit processing is completed, the counterfeit bills accumulated in the first and second accumulation and conveyance sections 21a and 21b can be continuously conveyed and guided to the storage section 15 in the same manner as described above.

Next, details of the banknote dispensing process will be explained with reference to FIGS. 6d and 6e. When the withdrawal mode is selected, the control unit 90 controls the mounting table 10 in the storage unit 15.
5. The press plate 107 is driven and controlled in the same manner as in the counterfeit bill processing mode, so that the banknotes can be accepted from the second stacking and conveying section 21b. Also,
The control unit 90 controls the first continuous conveyance solenoid 11
8 is energized to rotate the second banknote conveyance belt 115 in the direction D shown in FIG.

When the conveyance system drive motor 101 is driven in this state, the denominations designated for payment are taken out one by one from each bill storage section 16, 17, 18,
It is continuously conveyed along the path shown in FIG. 3d.
Note that since the first stacking and transporting section 21a is in the continuous transport mode, the banknotes are continuously transported without being stacked. Then, the first banknote determined to be payable is continuously conveyed along the path indicated by the dashed-dotted line shown in FIG. When interrupted, the control unit 90 controls the intermittent conveyance drive motor 109.
is rotated by a number of pulses corresponding to a distance shorter than the length of the banknote. By repeating this operation every time a banknote intercepts the third banknote detection sensor 143, the banknotes are intermittently conveyed while being stacked with their conveyance tips shifted, as shown in FIG. 6e. Then, the second accumulation conveyance section 2
Banknotes that are intermittently conveyed from 1b are stored in the storage section 15.
The end surfaces of the banknotes are brought into contact with the banknote stoppers 126 one after another inside the banknotes, and the banknotes are aligned in the mounting table 105.
It will be loaded on top.

When the last bill to be conveyed among the bills to be dispensed intercepts the third bill detection sensor 143, the slip issued in the card/passbook processing unit 10 is sent out from the slip output port 170 and is transferred to the second stack. It is supplied to the transport section 21b. When this slip intercepts the third bill detection sensor 143, it is intermittently conveyed in the same manner as the bill, and the slip is stacked with its conveying tip shifted from the conveying tip of the final bill. Thereafter, the second continuous conveyance solenoid 119 is energized and the second continuous conveyance section 21
b is set to continuous conveyance mode, and banknotes and slips are conveyed continuously.

As a result, the banknotes are aligned and stacked on the mounting table 105 in the storage section 15 with the slip placed on the top layer. Thereafter, based on the detection by the fourth bill detection sensor 144, the bill entry/exit door 123
is opened, and the user can take out bills to be paid through the bill slot 4.

In this way, it is possible to easily accumulate the bills to be dispensed without requiring a complicated structure such as an impeller, which can greatly contribute to miniaturization of the device. Furthermore, even when stacking a large number of bills, the bills held between the paper sheet conveyance belts are stacked with their conveying tips sequentially shifted, so regardless of the number of bills, the conveyor belt The thickness of the stacked banknotes is the same over the entire area. Therefore, it is possible to stack a large number of banknotes without difficulty, and also to transport them at high speed without taking any special measures. Furthermore, since the storage section 15 can selectively place both incoming banknotes and outgoing banknotes, and the banknote stopper 126 can also be used as a means for aligning both, the apparatus can be further miniaturized.

The present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the gist of the present invention. The paper sheet stacking device according to the present invention is not only applied to stacking rejected tickets or disbursed banknotes as in the above embodiments, but is also applicable to various other items in which paper sheets should be stacked in a stacked state. Needless to say, it can be applied. Further, the intermittent conveyance means 21b is not limited to one in which intermittent conveyance and continuous conveyance can be selected alternatively. By configuring intermittent and continuous conveyance as an alternative, sheets accumulated by intermittent conveyance can be rapidly conveyed to the storage section by continuous conveyance, contributing to speeding up of processing.

[Effects of the invention] As explained above, according to the present invention, with the above configuration, an impeller etc. as in the conventional example is unnecessary, and the device can be made smaller and lower in cost.
It is possible to provide an automatic transaction device in which a group of paper sheets is conveyed in a separated state and in a pinched state, so that stacking failure does not occur regardless of the number of sheets. In particular, a plurality of banknotes inserted at once are transported separately into genuine and counterfeit bills, and the counterfeit bills are held and stacked while shifting their positions on the transport path, until the accumulated amount reaches a predetermined amount. Since the counterfeit notes are returned when they are used up, it is possible to obtain the unique effect of further improving the reliability of deposit transactions.
