DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for processing banknotes and the like used in currency exchange machines, game machines, vending machines and the like.

[0002]

2. Description of the Related Art Conventionally, this kind of paper sheet processing apparatus is, for example, as shown in Japanese Patent Publication No. 55-28985 (B65H29 / 46), in which an identified banknote (conveyed one by one) is conveyed one by one from a conveying apparatus. Paper sheets) are temporarily received in the first chamber, and each time they are stacked one by one in a lower second chamber by a pressing member, and then the stacked banknotes are returned or stored.

Since it is usually necessary to stack hundreds of bills in the second chamber, the vertical dimension of the second chamber must be increased to some extent. Therefore, the moving distance of the pressing member becomes longer, and the time required for stacking becomes longer. On the other hand, since the bills are transported one by one, when the stacking time is long, the interval between the bills is increased to secure the stacking time, or the transport device is changed every time the stacking is performed. It must be stopped, and the time required for collecting bills increases.

Therefore, as shown in Japanese Patent Publication No. 57-51153 (G07D9 / 00), bills received on the first guide plate are reduced by a pressing frame by a certain small number on a guide plate one by one below. After stacking, the bills on this guide plate are collectively pushed up by the push-up plate and pushed into the upper bill stocker, so that the stacking time on the lower guide plate can be shortened and the overall stacking time can be shortened. .

[0005]

However, according to the structure as disclosed in Japanese Patent Publication No. 57-51153, the finally stacked bills are only collected in a bill stocker. There is a problem that a special dispensing device must be provided in order to use this.

Further, when pushing up a fixed number of bills stacked on the lower guide plate to the upper bill stocker, the push-up plate must pass along with a plurality of bills in the pressing frame in the middle. In fact, there is a problem that the operation becomes very difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and has as its object to provide a paper sheet processing apparatus capable of simultaneously executing collection and dispensing of paper sheets.

Another object of the present invention is to reduce the stacking time of paper sheets by simplifying the structure,
An object of the present invention is to provide a sheet processing apparatus that operates stably.

Still another object of the present invention is to provide a sheet processing apparatus capable of preventing a sheet from falling during operation and realizing a reliable stacking operation.

According to the paper sheet processing apparatus of the first aspect of the present invention,
If, for example, the stack by the spare stack means (spare stack)
Since the time can be shortened, the entire stacking time can be shortened by shortening the interval between the conveyed paper sheets. Further, during the stacking by the preliminary stacking means (preliminary stack), the papers stacked in this way can be paid out by the payout means, and the collection and the payout of the papers can be executed simultaneously.

According to the paper sheet processing apparatus of the second aspect of the present invention, as in the first aspect of the present invention, it is possible to shorten the time required for the preliminary stacking of the preliminary stacking elevator to the preliminary stacking section. By shortening the interval between the incoming sheets, the total stacking time including this stack can be reduced. Further, there is no need to provide any other driving means other than the driving means for driving the upper and lower elevators, and it is not necessary to equip each of the moved elevators with a driving device such as a solenoid or a motor.

According to the paper sheet processing apparatus of the third aspect of the present invention, in addition to the above, the conveyed paper sheet is held by the brush-like member located at the most downstream end with its end engaged with the brush-like member.

The width of the supporting portion 14 is larger than the width of the bill M, and the left and right sides of the supporting portion 14 are in the form of a rail, and are open up and down at intervals smaller than the width of the bill M. The hanging side 2B of the upper elevator 2 hangs toward this interval.

The pre-stack elevator 4 is composed of four side edges 4A located on both outer sides of the horizontal portion 3B of the support elevator 3, and a horizontal edge 4B formed at the lower end of the side edges 4A. You. At the upper end of the preliminary stacking elevator 4, an engaging portion 17 is vertically slidably engaged with four shafts 15 established on the upper surface of the horizontal portion 3B of the supporting elevator 3. This engaging part 1
7 is prohibited from moving at the upper end of the shaft 15, whereby the preliminary stacking elevator 4 and the supporting elevator 3 are vertically connected and contractible within the vertical dimension of the shaft 15. A spring 18 is interposed between the engaging portion 17 and the horizontal portion 3B and is wound around the shaft 15, and constantly urges the engaging portion 17 in a direction to push up the upper end portion of the shaft 15, thereby preparing the preliminary stack. Elevator 4 is stably held. The horizontal side 4B is the supporting elevator 3
Like the horizontal portion 3B, the left and right are rail-shaped, and the interval between the rails is opened up and down at intervals smaller than the width of the banknote M. With the engagement portion 17 at the upper end of the shaft 15, the horizontal side 4B is
The horizontal portion 3B is located below the horizontal portion 3B with a small interval.
A preliminary stack portion 19 having a width larger than the width of the banknote M is formed between the auxiliary stack portion 19 and B. Four bills M are stacked in the spare stacking section 19. At the front end of the horizontal side 4B, three bent sides 21 are provided upright within the width of the opening in the vertical direction of the horizontal side 4B. Then, a brush-like member 22 made of a plurality of cilia is attached. On the other hand, a portion corresponding to the bent side 21 at the front end of the horizontal portion 3B of the support elevator 3 is partially open, so that the brush-like member 22 also faces the front end inside the support portion 14.

The immovable member 5 has a sheet processing apparatus 1 on both upper ends.
Is fixed to a case or the like (not shown), and its position does not change. The immovable member 5 has a horizontal side 5A where the shaft 15 passes movably up and down and an upper surface of the pre-stack elevator 4 abuts on a lower surface thereof, and a hanging side hanging on both sides of the hanging side 2B of the upper elevator 2. 5
B. A pair of pulleys 2 on each side of which a conveyor belt 24 is stretched are provided on both sides of the lower end of the hanging side 5B.
5, 25, 26, 26, 27, 27 are rotatably mounted. The interval between the pair of pulleys 25, 26, and 27 is substantially the same as the interval between both left and right ends of the bent side 21, and faces the support portion 14 of the support elevator 3 from above.

The lower elevator 6 has a rail-like horizontal side 6A which is opened up and down at an interval smaller than the width of the banknote M, corresponding to a position below the horizontal side 4B of the spare stacking elevator 4. The base of the horizontal side 6A is fixed to a belt 31 which is driven up and down by a lower motor 30 as a driving means, so that it can be moved up and down. Below the horizontal side 6A of the lower elevator 6, a loading table 32 as a loading section on which the banknotes M are loaded is arranged.

The dispensing device 13 is composed of dispensing rollers 34 and 35 attached to the rear of the loading table 32 and a separation roller 36 provided corresponding to the dispensing roller 35. The payout rollers 34 and 35 are formed by attaching rubber to the peripheral surface of an aluminum roller at, for example, a range of 150 degrees, and rotate clockwise in FIG. 2 to move the lowermost bill M on the loading table 32 backward. It is what you send out. When two separation rollers 36 are sent out at the same time, the separation rollers 36 rotate in the same direction as the payout rollers 34 and 35 to send back the upper bill M.

A transport device 38 for the banknote M is provided behind the paper sheet processing apparatus 1. The transport device 38 is composed of upper and lower pulleys 39 and 40 and upper and lower transport belts 41 and 42 and the like stretched over the pulleys 39 and 40, respectively. The transport belt 24 is stretched over the upper pulley 39. Is done.

Next, the operation of the paper sheet processing apparatus 1 of the present invention having the above configuration will be described. FIG. 1 and FIG. 2 show the standby state. In this standby state, the supporting elevator 3 is engaged with the push-up side 12 of the upper elevator 2, the lower edge of the hanging side 2B of the upper elevator 2 is located on the upper edge of the horizontal section 3B, and the actuator 9 is located on the lower side. At the height of the optical sensor 10. Also, shaft 1
5 is located on the horizontal side 5A of the stationary member 5, the engaging portion 17 of the pre-stack elevator 4 is positioned at the upper end of the shaft 15, and the pre-stack elevator 4
Is in contact with the lower surface of the horizontal side 5A of the immobile member 5.
Further, the lower surface of the transport belt 24 is located at the lower edge of the support portion 14, and the lower elevator 6 presses the bill M on the loading table 32 below the preliminary stack elevator 4 from above.

In this state, the transport belt 4 of the transport device 38
The banknotes M are conveyed one by one from the positions 1 and 42 at a predetermined interval, and sent into the support portion 14 of the support elevator 3 from behind by the conveyor belt 24. The brush-like member 22 is located at the most downstream position of the flow of the bill M, and the front end of the fed bill M is
2 between cilia (see FIG. 2). Therefore, even if the transported banknote M is bent and deformed, the banknote M is held,
It does not fall from the support part 14.

When the banknote M enters the support portion 14, first, a preliminary stack is started. That is, the upper motor 7 is driven to move the upper elevator 2 upward. As the upper elevator 2 rises, the supporting elevator 3 also rises,
The preliminary stack elevator 4 cannot be raised because its upper surface is in contact with the lower surface of the horizontal side 5A of the immobile member 5. Therefore,
Only the shaft 15 is raised together with the supporting elevator 3, the spring 18 is compressed, and the pre-stacking elevator 4
Is more firmly pressed against the immovable member 5. On the other hand, the hanging side 5B of the immobile member 5 relatively lowers due to the rise of the support portion 14, and the transport belt 24 pushes down the bill M in the support portion 14 (see FIGS. 3 and 4).

Further, when the upper elevator 2 moves up and the actuator 9 reaches the height of the upper optical sensor 11, the upper motor 7 stops, and the raising of the upper elevator 2 stops.
In this state, the horizontal portion 3B of the supporting elevator 3 has risen above the conveyor belt 24 of the immobile member 5, and both ends of the banknote M are disengaged from the horizontal portion 3B and the preliminary stacking portion 19 below.
And is stacked (preliminary stack) (Fig. 5
And FIG. 6). While the support elevator 3 is rising, wind pressure is applied to the banknotes M in the support portion 14, but the banknotes M are held because the tips are cut into the brush-like member 22, and thus the banknotes M are held by the rising wind pressure. Will not fall. The distance between the pulleys 25 and 27 and the brush-like member 2
Since the existence ranges of the two coincide, the bill M can be bent without difficulty even when the bill M is pushed downward by the transport belt 24.

Thereafter, the upper motor 7 rotates in the reverse direction to lower the upper elevator 2. When the actuator 9 comes to the position of the lower optical sensor 10, the upper motor 7 stops, and the upper elevator 2, the supporting elevator 3 and the spare stacking elevator 4 are in the same standby state as in FIGS. It returns (see FIGS. 7 and 8). At this time, the tip of the bill M pushed into the spare stack portion 19 gets into the brush-like member 22, so that the bill M does not drop even by the wind pressure accompanying the lowering of the spare stack elevator 4. The above-described preliminary stacking operation is repeated four times to stack four bills M (only three bills are shown in FIG. 7 and thereafter) in the preliminary stacking unit 19, and the preliminary stacking ends.

Here, since only four banknotes M are stacked in the preliminary stacking section 19, the vertical dimension of the preliminary stacking section 19 is small. Therefore, the moving distance (up and down) of the upper elevator 2 can be shortened, so that the time of the preliminary stacking operation becomes extremely short. In the embodiment, the time required from the start (FIGS. 1 and 2) to the end (FIGS. 7 and 8) of one preliminary stack operation is one second. This means that the transport device 38
This means that the interval between bills M sent from the company can be reduced to 1 second.

When the above preliminary stack is completed, the transport device 38 is temporarily stopped, and the sheet processing apparatus 1 starts the main stack next. That is, the upper motor 7 is driven from the state of FIGS. 7 and 8 to lower the upper elevator 2. With the lowering of the upper elevator 2, the supporting elevator 3 and the spare stack elevator 4 also descend, and the horizontal side 4B of the spare stack elevator 4 comes into contact with the horizontal side 6A of the lower elevator 6 soon. Thus, the lowering of the supporting elevator 3 and the preliminary stacking elevator 4 is completed. Although the preliminary stacking section 19 also descends due to the descending of the preliminary stacking elevator 4, the banknotes M in the preliminary stacking section 19 do not fall down due to the wind pressure at the time of descending because the banknotes M enter the brush-like member 22. Meanwhile, the upper elevator 2
Still rises, its push-up side 12 is separated from the supporting elevator 3, the hanging side 2B passes through the supporting section 14 and the preliminary stacking section 19, and comes into contact with the four bills M in the preliminary stacking section 19. It is pressed against the bill M on the push-down loading table 32 (see FIGS. 9 and 10).

In this state, the upper elevator 2 stops, and then the lower motor 30 is driven to raise the lower elevator 6. The elevation of the lower elevator 6 raises the spare stack elevator 4 and the support elevator 3. On the other hand, since the four bills M in the preliminary stacking section 19 are pressed against the bills M on the loading table 32 by the hanging side 2B of the upper elevator 2, both ends of the banknotes M are preliminarily stacked by raising the preliminary stacking section 19. Removed from part 19,
It is pushed onto the loading table 32 (this stack, see FIGS. 11 and 12).

The bills M in the preliminary stacking section 19 are
2, the lower motor 30 rotates in the reverse direction to lower the upper elevator 6 (simultaneously, the supporting elevator 3 and the spare stack elevator 4 also lower), and the loading table 32
The upper bill M is pressed from above (see FIGS. 13 and 14).
Next, the upper motor 7 is driven to raise the upper elevator 2. As the upper elevator 2 rises, the supporting elevator 3 and the spare stack elevator 4 also rise, and when the actuator 9 rises to the position of the optical sensor 10, the upper motor 7 stops, and the standby state shown in FIGS. Return,
This stack operation ends.

Here, since several hundred (for example, 800) banknotes M are stacked on the loading table 32, the loading table 32 and the standby stack elevator 4 in the standby state are stacked.
And the distance between them increases. Therefore, in the embodiment, the time required from the start (FIGS. 7 and 8) of the stack operation to the return to the standby state is 3 seconds. Therefore, when the above-mentioned main stack is executed for each of the conveyed banknotes M without performing the preliminary stacking, it takes a total of 12 seconds to stack the four banknotes M on the loading table 32. Will be. Also, the interval between bills must be set to 3 seconds.

On the other hand, by executing the preliminary stack and the main stack as in the present invention, four banknotes M are pre-stacked in four seconds, and then the whole is fully stacked in three seconds. Is completed in a total of 7 seconds to stack the banknotes M on the loading table 32. Thus, the overall time required for the stack is significantly reduced.

The driving means includes upper and lower motors 7 and 30.
Only the preliminary stack and the main stack operation are achieved only by the vertical movement of each of the elevators 2, 3, 4 and 6. Therefore, there is no need to provide a motor or a solenoid for each of the elevators 2, 3, 4 and 6 which actually move up and down, so that no electric wiring is required, the moving part is simplified, and the weight of the moving part is reduced, so that the motor 7 or 30
The load on the system is also reduced.

The banknotes M loaded on the loading table 32 by the above-mentioned spare stack and main stack are paid out by the payout device 13 to be used for change or the like. Next, the payout operation will be described. Rubber is partially attached to the payout rollers 34 and 35 as described above.
By rotating in the clockwise direction, the lower banknote M on the loading table 32 is moved backward. At this time, when two or more sheets are moved while being overlapped, the upper bill M is sent back in the direction of the loading table 32 by the separation roller 36. The bills M sent one by one to the rear in this manner are conveyed to a payout slot by a conveying device (not shown).

Since the preliminary stacking operation is performed independently of the lower elevator 6, the banknotes M on the loading table 32 can be dispensed by the dispensing device 13 even during the preliminary stacking. Accordingly, the collection of the banknotes M by the upper elevator 2, the supporting elevator 3, and the preliminary stacking elevator 4 and the payout of the banknotes M by the payout device 13 can be executed in parallel.

Although the embodiment has been described with reference to the banknote M as a paper sheet, the present invention is not limited to this, and the present invention is also effective for coupons and the like.

[0038]

According to the first aspect of the present invention, the stacking time by the pre-stacking means can be shortened, so that the interval between the conveyed paper sheets is shortened, so that the entire stack including the main stack is reduced. Stacking time can be shortened. Further, it is possible to pay out the stacked sheets by the paying-out means during the stacking by the preliminary stacking means, and it is possible to simultaneously collect and pay out the paper sheets.

According to the second aspect of the present invention, it is possible to shorten the pre-stacking time of the pre-stacking elevator in the pre-stacking section in the same manner as in the first aspect of the present invention. By shortening the interval, it is possible to shorten the entire stack time including this stack. In addition, since there is no need to provide another driving means in the moving part other than the driving means for driving the upper and lower elevators, wiring and the like to the moving part are not required, thereby simplifying the structure. .

According to the paper sheet processing apparatus of the third aspect of the invention, the paper sheets conveyed in addition to the above inventions are held by the brush-like member located at the most downstream end, with the end of the paper sheet being bitten. Therefore, even when the support portion moves up and down, the support portion does not drop due to wind pressure, and a reliable stack of paper sheets can be realized.
