Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet stacking device which is mounted on an automatic transaction device installed in a financial institution such as a bank and used for stacking banknotes.

[0002]

2. Description of the Related Art For example, in an automatic teller machine in which paper sheets such as banknotes are carried in one by one and stacked in a stacked state, the depth of the stacking portion of the paper sheets has a great influence on the performance. Has become.

That is, when the depth of the stacking portion is too shallow, the rear end of the paper sheet carried in front collides with the front end of the paper sheet carried in next, and the depth of the paper sheet collides. If the depth is too deep, the paper sheets will stand up instead of being horizontal, causing a stacking error.

Conventionally, in this type of stacking device, the stacking bottom surface of the stacking portion of the paper sheets is of a fixed depth type, or the stacking bottom surface is arranged according to the number of stacked sheets of paper that are carried in. There is a variable depth type that controls the descent.

[0005]

However, in a stacking device of such a conventional structure that the stacking portion of paper sheets has a fixed depth, the stacking bottom surface is fixed, and thus there is a limit to the stacking depth. As a result, the number of paper sheets accumulated is small.

Moreover, in order to process a large number of paper sheets, it is necessary to repeatedly carry out a troublesome process of carrying in and collecting a certain number of sheets, transferring them to another place, and then carrying in the paper sheets again. However, the device itself is complicated and the processing efficiency is poor.

On the other hand, in the case of the variable depth type, although the quality of the paper sheet is constant and can be processed when it is relatively good, when the quality of the paper sheet is poor and the number of stacked sheets increases. However, even with the same number of stacked sheets, there is a difference in the stacking height of the paper sheets, and the height is about 5 times or more as compared with that in the good case. Since it is not possible to cope with changes in the stacking depth, there is a problem in that the stacking depth of paper sheets cannot be optimized and there is a large variation in performance.

The present invention has been made under the above circumstances, and its purpose is to maintain the optimization of the accumulation depth of paper sheets regardless of the quality of the paper sheets. ,And,
An object of the present invention is to provide a paper sheet stacking apparatus capable of favorably carrying out stacking processing of a large number of sheets by reducing variations in performance.

[0009]

In order to solve the above-mentioned problems, the present invention provides a stacking device for stacking paper sheets carried into the apparatus body in a stacked state, wherein A shutter mechanism capable of moving the shutter in a direction perpendicular to a paper surface of a paper sheet, a shutter lower end detecting means for detecting a lowermost end position of the shutter of the shutter mechanism, The uppermost paper sheet detecting means for detecting the position of the uppermost layer of the paper sheets accumulated on the shutter, and the paper sheets accumulated above the shutter provided above the shutter in the main body of the apparatus. First paper sheet pressing means for pressing downward by a certain amount of reciprocating motion,
The first paper sheet pressing means is movable in the direction perpendicular to the paper surface so as to press and support the upper surface of the paper sheet pressed by the first paper sheet pressing means, and is openable / closable toward the outside of the apparatus main body. The paper sheet pressing means 2 and the uppermost paper sheet detection means detect that the uppermost layer of the paper sheets accumulated on the shutter has exceeded a certain position, and the shutter lower end detection means. When it is detected that the shutter is at the lowermost position, the carrying-in of the paper sheets into the apparatus main body is temporarily stopped, and the first
The downward movement of the paper sheet pressing means and the outward opening operation of the second paper sheet pressing means make it possible to press the paper sheet downward, and the upper surface of the paper sheet is the second paper sheet. After pressing and supporting by the closing operation of the paper pressing means, the first paper pressing means is returned to the original position, and the paper is again started to be loaded into the apparatus main body, and this paper is loaded. And a control means for controlling the accumulated paper sheets to be accumulated on the second paper sheet pressing means.

[0010]

That is, according to the present invention, the uppermost layer of paper sheets accumulated on the shutter is detected, and when the uppermost layer exceeds a certain position, the shutter position is sequentially lowered to accumulate the paper sheets. When the shutter is located at the bottom end and the uppermost layer of paper sheets exceeds a certain height, the carry-in of the paper sheets is temporarily stopped and the paper sheets accumulated on the shutter are 1
The paper sheet pressing means is pressed by the lowering operation, and the upper surface of the paper sheet pressed by the first paper sheet pressing means is moved to the second side.
After being pressed and supported by the paper sheet pressing means, the paper sheets are controlled to be restarted to be loaded into the apparatus main body and the subsequent paper sheets are accumulated on the second paper sheet pressing means. Therefore, due to the pressing action of the first paper sheet pressing means and the pressing support action of the second paper sheet pressing means, a sufficient entry space for the upper portion of the stacked paper sheets after resumption of loading is secured. Thus, a large number of sheets can be stably accumulated without being restricted by the quality of the sheets.

Then, when the bill A is taken out from the bill storage chamber 454, the shutter 8 is closed again.

In the figure, reference numeral 50 denotes a magnet built in the loading chamber 19. The magnet 50 is installed in the loading unit 100 when the loading chamber 19 is loaded in the loading unit 100 of the upper unit 14a of the apparatus body 1. Reed switch 5
1, the set state can be detected.

Next, the flow of the banknote A in the dispensing operation will be described. First, when the dispensing transaction is selected and the withdrawal amount is subsequently input, below the safes 16, 17, 18, 20. By pressing the upper holding plates 80a to 80c, the stored bill A is taken out from the rollers 304a to 304.
The banknotes A are taken out one by one so as to come into contact with c and 304e.

In this case, the 10,000-yen ticket is taken out of the safe 16, the 1,000-yen ticket is taken out of the safe 17, and the 5,000-yen ticket is taken out of the safe 18 one by one by rotating the take-out rollers 304a to 304c. Then, it is conveyed horizontally to the front, and after that, the direction is changed upward to be guided to the upper unit 14a through the conveyance path R7 and conveyed to the inspection unit 36.

A bill A which is judged to be a genuine bill by the inspection section 36
Are the first, second, third and fourth distribution gates 39a,
Withdrawal temporary collection unit 37 via 39b, 39c and 39d
Accumulated in.

In this way, when the banknotes A have been accumulated to the predetermined withdrawal amount in the withdrawal temporary accumulating section 37, the withdrawal of the banknotes A is stopped, and then the withdrawal accumulated in the withdrawal temporary accumulating section 37. The banknotes A are discharged to the banknote storage chamber 454 as a bundle, and at the same time, the shutter 8 is opened and paid out to the user.

When the user withdraws the dispensed bill A, the shutter 8 is closed again, whereby the dispense transaction is completed.

Next, the flow of banknotes in the deposit return operation will be described. In the deposit operation, after the banknotes A are accumulated in the deposit temporary accumulating section 38, for example, the CRT display section 9 is displayed.
When the cancellation is further input, the banknotes A are discharged as a bundle into the banknote storage chamber 454, the shutter 8 is opened and returned to the user, and the user extracts the banknote A from the banknote storage chamber 454. Then, the shutter 8 is closed again.

On the other hand, the flow of the banknotes in the banknote forgetting and collecting operation is such that the user keeps the dispensed banknote A in the banknote storage chamber 4 even if a certain time has elapsed with the shutter 8 opened.
When the bills are not taken out from 54, the shutter 8 is first closed, and then the bills A in the bill storage chamber 454 are taken in one by one.

The bill A thus taken in
Is sent to the collection box 27 or 28 in the deposit box 20 via the inspection section 36, the first, sixth, tenth, or eleventh distribution gate 39a, 39f, 39j, or 39k, and is collected and collected there. It is supposed to be done.

Next, the flow of bills in a bill loading (replenishing) operation for an unmanned working day on a holiday will be described. First, before the holidays, an operator opens and closes and a detachable opening and closing is provided on the rear surface of the loading safe 19. The door 19a is unlocked, and the opening / closing door 19a is opened rearward or removed to set the bill A.

After the bill A is set as described above, the opening / closing door 19
After a is closed and locked again, the banknote loading mode is selected by the attendant, whereby the unmanned banknote A loading operation is started.

That is, the bill A is taken out one by one by the take-out roller 304d of the loading safe 19, is conveyed through the second, third and fifth sorting gates 39b, 39c and 39e and is guided to the inspection section 36. He then distinguishes the denominations.

The bill A discriminated by the inspection section 36 is conveyed downward by the first sorting gate 39a, and further, the eleventh sorting gate 39k and the sixth sorting gate 3
Sent via 9f.

In this case, the seventh distribution gate 3
The 1,000-yen ticket through 9g has its course changed at the eighth sorting gate 39h, and the stacking unit 301 of the safe 17 as a 1,000-yen storehouse.
b), and the 10,000-yen tickets are the 7th sorting gate 3
The route is changed by the ninth distribution gate 39i via 9g and accumulated in the accumulating section 301a of the safe 16 as a ten thousand yen store.

Further, the course of the 5,000 yen ticket is changed by the seventh distribution gate 39g through the sixth distribution gate 39f and accumulated in the accumulation section 301c of the safe 18 as a 5,000 yen store. It is pushed and stored in the stacking storage section.

Further, the bill A, which has been discriminated as one to be rejected by the inspection section 36 at the time of loading, is sorted upward by the first sorting gate 39a and passed through the second and third sorting gates 39b and 39c. It is returned to the loading box 19 or accumulated in the temporary withdrawal accumulating section 37.

When accumulating in the temporary withdrawal accumulating section 37, the ticket (replacement ticket) taken out from the loading box 19 and passed through the second sorting gate 39b and the reject ticket are the second sorting gate 39b and the third sorting gate. When a reject ticket is generated, the removal is stopped instantaneously, the reject ticket passes through the transport path R4, and then is removed again. The method of restarting the operation or transporting the ejected ticket (replacement ticket) and the reject ticket in an overlapping state and accumulating them in the withdrawal temporary accumulating section 37 as they are is adopted. When the banknote A in the storage 19 is exhausted, the loading operation ends.

When a reject ticket is generated,
The reject ticket is stored in the banknote storage chamber 4 from the temporary withdrawal collection unit 37.
After being conveyed to 54, taken in one by one by the take-in roller 403a, and again inspected by the inspecting unit 36, the denomination-determined ticket is guided to the lower unit 14b by the first distribution gate 39a, and The coins are stored in the safes 16, 17, and 18 according to the type of money.

Here, the ticket rejected again is the first
Is guided downward by the distribution gate 39a of the sixth distribution gate 39f, the sixth distribution gate 39f, the tenth distribution gate 39j, and the eleventh distribution gate 39j.
It is accumulated and stored in the collection box 29 of the reject box 21 via the sorting gate 39k and the twelfth sorting gate 39l.

Next, the flow of bills in the close inspection operation will be described. The bill A of the 10,000-yen bill taken out from the 10,000-yen store 16 is conveyed to the upper unit 14a through the conveyance path R7 and then conveyed to the inspection unit 36. Is done and is inspected.

The bill A inspected by the inspecting section 36 is guided to the conveying path R5 by the first sorting gate 39a, conveyed to the lower unit 14b and returned to the ten thousand yen storage 16. This is continued until the remaining detection sensor 41k detects that the lower bill A is gone.

In this case, when a reject ticket such as an unidentifiable one is generated in the inspection section 36, the sixth, tenth and eleventh
And the 12th distribution gates 39f, 39j, 39k, 3
It is adapted to be collected and collected in the collection box 29 of the reject box 21 via 9 l.

By the way, it is very important in this kind of automated equipment whether or not this is efficiently performed in the work involved in the processing of a large amount of bills such as the above-mentioned loading or scrutiny of bills A.

In the embodiment of the present invention, the safes 16 to 18 and the loading storage 19 can accept the bills A at the same time while taking out the bills A, and the total amount of each safe is nonstop. It is configured so that it can be continuously accumulated.

For this reason, conventionally, when such an automated device loads bills, for example, 100 bills are stacked and stored in another place, and this storing operation is repeated to load the full capacity or to perform detailed inspection. In this case, there was no choice but to adopt a method of once counting all the bills from each safe to the loading box and counting them again, and then returning them from the loading box to each bank again, which took a lot of time. On the other hand, in the present invention, by adopting the configuration described later, it is possible to significantly save time.

FIGS. 1 and 5 to 20 are schematic diagrams showing the construction of the paper sheet stacking apparatus according to the present invention, that is, the safes 16 to 18 and the loading storage 19 are, for example, first-in / first-out safes. In the figure, reference numeral 200 denotes the apparatus main body.

As shown in FIG. 5, in the main body 200 of the apparatus, the banknote A sequentially conveyed from the conveying path of the automatic transaction apparatus 1 described above is fed by the cone roller 201 and the pinch roller 2.
It is sandwiched by 02 and integrated on the shutter 204 which constitutes the shutter mechanism.

The cone roller 201 is nested with the pinch roller 202, and the banknote A is attached to the cone roller 201,
At the time of stacking, both side walls 206, 206 of the device body 200
It is designed to prevent buckling when it comes into contact with.

Further, the cone roller 201 is provided with a ratchet wheel 203 having a plurality of flexible blades radially attached to the cone roller 201 so as to be coaxially rotatable in synchronization with each other. By pressing the rear end of the banknotes A accumulated on the sheet 204 downward, an entry space for the banknotes A to be conveyed next is secured.

In the figure, 205 and 205 are the shutters 204.
A pair of upper holding plates spaced apart below each other, the upper holding plates 205, 205 push downward the upper surface of the stored bills or uncounted bills accumulated on the inner bottom side of the apparatus main body 200, By this, it is possible to prevent rising of eccentric bills and fluffy bills.

On the other hand, the shutter 204 is movable in the direction perpendicular to the paper surface of the banknote A, and the shutter descending sensor 219 as a detecting means installed in the vicinity of the cone roller 201 allows a space for entering the banknote. When it is detected that the bills are not sufficient, the descent is controlled so as to secure the entry space for the bills, whereby stable bill accumulation is achieved.

Then, when the conveyance of the bill A is stopped, as shown in FIG.
As shown in FIG.
5, 205, a position provided with a certain distance is detected by a descending position detecting means (not shown) and descends, and at the descending position,
The shutter 204 and the upper pressing plates 205, 205 are both rotated in the opening direction so that the banknotes A stacked on the shutter 204 are dropped on the banknotes stacked below the upper pressing plates 205, 205. There is.

At this time, both side walls 2 of the apparatus main body 200
The shutters 206 and 206 are pushed by the shutter 204 and are allowed to escape outward by the thickness of the shutter 204, thereby facilitating the falling of the banknote A.

When the banknotes A accumulated on the shutter 204 are dropped in this way, as shown in FIG.
A pusher 20 provided above the shutter 204 so as to be able to move up and down.
7 descends from above inside the apparatus main body 200, and the upper holding plate 2
The banknotes accumulated below 05 and 205 are pressed.

In this state, the shutter 204 and the upper pressing plates 205, 205 rise to the uppermost position where they can be rotated while maintaining the open state, and at that position, they are rotated in the closing direction again to the original closed state. Upon returning, the device body 200
Both side walls 206, 206 also return to their original state.

In this way, when the shutter 204 and the upper holding plates 205, 205 are raised to the uppermost position and returned to the original closed state, as shown in FIG.
05 descends and presses the bill.

9 to 12 show the counting operation of the number of banknotes A accumulated in the apparatus main body 200. As shown in FIG. 9, the feed roller 208 and the feed roller are arranged from the lower side of the apparatus main body 200. 209 and gate roller 2
The bills are separated and taken out one by one by 10, the denomination and the number of bills are counted by the inspecting unit 211, and then sequentially accumulated on the shutter 204 again. It is stored in a reject box 218 provided in the upper part of 200.

In this case, when the banknotes are separated and taken out one by one, it is possible to stably take out up to a certain number of banknotes by the frictional force generated between the banknotes and the feed roller 208 due to its own weight. If the number of sheets becomes lighter when the number of sheets is below, the removal of bills becomes unstable.

However, as shown in FIG. 10, since the upper pressing plates 205, 205 are provided so as to be separated from each other, the upper surfaces of the stacked banknotes A can only be partially pressed, In this case, it is impossible to always take out the bills stably.

Therefore, according to the present invention, when the number of accumulated bills A is reduced to a certain number or lowered to a position where the uppermost surface of the bills A is lowered, the upper holding plates 205, 205 are raised to be placed on the shutter 204. The accumulated counted banknotes A are supported.

Then, in this state, as shown in FIG. 11, the shutter 204 is lowered to leave the remaining uncounted banknotes A.
By pressing the uppermost surface of the banknote, stable banknote removal can be continued. This simplifies the mechanism and the banknote removal operation is shown in FIG. As described above, the counting operation is completed by confirming that there is no banknote in the detection operation by the banknote residual detection sensor 212 installed in the lower part of the apparatus main body 200, and the counting operation is completed.

FIG. 13 and FIG. 14 show a banknote stacking unit in a conventional apparatus. In the related art, operation control of the shutter 204 is performed according to the number of banknotes A stacked on the shutter 204. However, as described above, when the quality of the banknotes is poor, as shown in FIG. 13, the banknotes of good quality cannot be completely pressed by the tapper wheel 203 even if the stacking depth is just good, so As A rises and prevents the next bill A from entering, it causes a jam.

On the other hand, in the case of a government-sealed ticket or the like, as shown in FIG. 14, when the stacking depth becomes too deep, the bill A rises, and a jam occurs due to the rise of such bills. Easy to do.

As described above, the conventional stacking means cannot cope with the difference in the stacking height depending on the quality of the banknotes, and the banknotes cannot be stably stacked continuously.

Then, as shown in FIG. 1, when a certain number (for example, a relatively small number of about 100) of banknotes A are accumulated on the shutter 204, the carry-in of the banknotes is once stopped and the pusher 207 is placed on the upper surface. The bills A accumulated on the shutter 204 are stored by lowering the holding plates 205, 205 to the lower side, and the stored bills A are held by the upper holding plates 205, 205, and then the pusher 207 is removed. Although a method of causing the banknote A to be carried in again after performing a series of storing operations of raising it to the position 1), this alone takes a very long processing time.

According to the present invention, in the banknote stacking device as shown in FIG. 1, the shutter 204 shown in FIGS.
The control operation of is performed.

That is, as shown in FIG. 15, when the banknotes A are successively stacked on the shutter 204, the trailing edge of the banknotes is pressed down by the tapper wheel 203 to a position of a certain number of sheets, and the banknotes A are inserted. Secure space. At this time, the output of the shutter lowering detection sensor 219 has a timing chart as shown in FIG.

Then, when the bill A is further carried in, the tapper wheel 203 cannot press the bills completely, so that the uppermost surface of the bill is normally the tapper wheel 203, as shown by the dashed line in FIG. Will be stacked above the pressing position by.

At this time, since the upper bill A blocks the optical axis of the shutter lowering detection sensor 219, the output of the shutter lowering detection sensor 219 becomes a timing chart as shown in FIG. 20, and the dark time of this output. 16 exceeds a certain time t, the shutter 204 descends as shown in FIG. 16, and the output of the shutter descending detection sensor 219 is changed to that shown in FIG.
By returning to the timing chart as shown in FIG. 9 and repeating such operations in sequence, it is possible to stably stack the bills A that are continuously carried in.

Further, as shown in FIG. 17, the shutter 20
4 is lowered to the lowermost position, it is detected by a shutter lower end position detection sensor (not shown), and the output of the shutter lowering detection sensor 219 is changed to a timing chart as shown in FIG. To stop.

At this time, since the upper portion of the banknotes A accumulated on the shutter 204 is in a free open state and is fluffy and unstable, as shown in FIG.
By lowering 07 below the upper pressing plates 205, 205, the upper surfaces of the banknotes A stacked on the shutter 204 are pressed, and the upper pressing plates 205, 205 are rotated in the closing direction to move the banknotes A of the banknotes A. By pressing the upper surface, the entry space is secured and the next bill can be carried in.

According to the above-described structure of the present invention, however, the entire capacity of the main body 200 of the apparatus can be processed by the continuous stacking method, but the quality of the banknotes is poor and must be pressed. For example, in the case where the number of stacked sheets becomes small, the continuous stacking method is used up to the middle to efficiently perform processing, and thereafter, the pusher 207 presses the upper surface of the banknotes stacked on the shutter 204 to perform accurate stacking. By controlling so as to secure the number of sheets, the processing efficiency is improved together with the accumulation time and the storage space.

In the embodiment of the present invention, FIG.
From FIG. 18, as shown in FIG.
Between 6 and 206, the upper part has a narrower width, and the lower part has a wider part from a certain position.

That is, the bills conveyed in the upper part of the apparatus main body 200 are aligned, and the apparatus main body 200 in the lower part is aligned.
When reducing the friction between the both side walls 206, 206 of the bill A and the bill A, thereby moving the bill A from the top to the bottom,
The pressing force to the feed roller 208 on the lowermost surface of the bills accumulated on the shutter 204 is kept constant to improve the bill taking-out performance.

As is apparent from the above description, according to the present invention, the uppermost layer of paper sheets accumulated on the shutter is detected, and when the uppermost layer exceeds a certain position, the shutter positions are sequentially changed. When the paper sheets are collected by stacking them down, the shutter is located at the lowermost end, and when the uppermost layer of the paper sheets exceeds a certain height, the carry-in of the paper sheets is temporarily stopped and The sheets stacked on the sheet are pressed by the lowering operation of the first sheet pressing unit, and the upper surface of the sheet pressed by the first sheet pressing unit is pressed by the second sheet. After pressing and supporting with a means, carry-in of the paper sheets to the apparatus main body is restarted,
Since the subsequent sheets are controlled so as to be accumulated on the second sheet pressing means, the pressing action by the first sheet pressing means and the second sheet pressing means are performed. With the pressing support action, it is possible to sufficiently secure the entry space above the accumulated paper sheets after the resumption of loading, and thus, it is possible to improve the space efficiency and
The accumulation processing of a large number of sheets can be stably performed without being restricted by the quality of the sheets as in the past.
