DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet holding device for use in an automatic bill dispensing apparatus having a mechanism for dispensing a plurality of bills in a stacked state, and for example, temporarily stores bills inserted by a user in a safe. In addition, the present invention relates to a paper sheet holding device suitable for a recirculation-type banknote payout device that takes out a required number of sheets from a safe as needed.

[0002]

2. Description of the Related Art Devices having a bill payout mechanism such as a currency exchange machine, a cash depositing / dispensing machine, and a vending machine (hereinafter referred to as a bill payout device,
In the case of dispensing a plurality of bills, bills taken out one by one from a built-in safe are stacked in a holding device to form a bill bundle, and the bill bundle is collectively paid out to a user from a payout port. It is configured as follows. The above-mentioned bill storage device receives a bill transported from a safe or the like and transports the bill, and receives bills sent from the transport mechanism located downstream of the transport mechanism one by one and deposits them on a stack table. And a discharge mechanism that operates when a required number of sheets are stacked on the stack and discharges the bundle of sheets to the outside of the apparatus at a time. In the stacking section, besides the type that stacks the fed banknotes while securely holding them one by one on the stacking table, it also has a simple holding mechanism and allows the banknotes to fall freely on the stacking table and be deposited There is. The former type has an advantage that a stack defect on a stack table is unlikely to occur, but has a disadvantage that the configuration is complicated and the size is increased.
On the other hand, the latter type of paper sheet holding device has an advantage that the configuration can be simplified, downsized, and thinned. However, in the latter type of bill holding device,
When the bill used for dispensing is a habit tag having a habit such as wrinkles or breakage, there is no mechanism for sufficiently controlling the habit, and therefore, the banknote is transported while being suppressed by the transport belt constituting the transport mechanism. After that, when it is released on the stack table,
The habit shape returns to the original shape, causing poor deposition,
Alternatively, the possibility of colliding with the already-stacked banknotes to cause a stacking defect increases. From such a point, in the latter type of bill storage device, when the transport mechanism transports the banknote along its longitudinal direction, the transport mechanism forms a V-shaped habit in the width direction and transports the banknote while stretching the wrinkles. In addition, there has been proposed a bill storage device in which a wrinkle straightening roller is disposed in a transport mechanism.

FIGS. 4 (a) and 4 (b) are a front view and a side view, respectively, showing the structure of a main part (transport mechanism) of such a conventional bill holding device. And the outer endless belts 1 and 2 for transporting the outer endless belts 1 and 2, and wrinkle straightening rollers 3 located at the center of both outer endless belts 1 and 2. The outer endless belts 1 and 2 consist of upper and lower endless belt pairs 11, 12 and 13, 14 respectively, and each endless belt pair 11, 1
2, and 13, 14 are introduction rollers 11a, 12 respectively.
a, 13a, 14a and discharge rollers 11b, 12b, 13
b, 14b and is driven to rotate in the direction of the arrow. The endless belts 11, 12, 13, 14 constituting the outer endless belts 11, 12 have the same width, length, and other dimensions, and the diameter of the rollers supporting each belt is also constant. The outer endless belts 1 and 2 are arranged to face each other as shown. At an intermediate position between the upper endless belts 11 and 13, a wrinkle-stretching roller 3 is arranged coaxially with each of the discharge rollers 11b and 113b. The diameter of the wrinkle reducing roller 3 is configured to be larger than the diameter of each of the discharge rollers 11b and 13b facing each other. Therefore, the wrinkle straightening roller 3 can push down the central portion of the bill to be conveyed by the insertion amount shown in FIG. 4 (b). The bill S introduced along the longitudinal direction from the direction of the arrow A in FIG. 4 (a) has its upper and lower surfaces at both ends in the width direction directed downstream while being nipped by the upper and lower belts 11, 12, 13 and 14. Conveyed and released rollers 11b, 1
When the roller 3 reaches the position 3b, the roller 3 is pressed down by the outer peripheral edge (flange 3a) of the wrinkle straightening roller 3 and deformed into a substantially V shape. In this way, the banknotes are transported and discharged while being deformed in a V-shape by the wrinkle straightening roller 3 located at the terminal end of the transport mechanism, so that even if the bills are wrinkled or broken, the bills are discharged from the transport mechanism. Since the V-shaped deformation remains when it is stacked on the stack table 15, it is possible to prevent a return to a habited original shape to some extent, thereby preventing poor deposition.

[0004] However, in practice, a sufficiently V-shaped banknote S can be prevented from being returned to its original shape after the banknote S having a habit strong enough to cause a stacking defect on the stack table is discharged from the transport mechanism. Forming the deformation was difficult with a conventional bill storage device. That is, in the above-mentioned conventional banknote holding device, both ends of the banknote S in the width direction are strongly nipped by the upper and lower endless belts 11, 12, 13, and 14, respectively, while the center portion in the width direction is wrinkled by the wrinkling roller 3. Forcing down, forcibly depressing the central portion of the banknote, the wrinkle stretches to the central portion of the banknote.
Scars remain and cause damage to banknotes. For this reason, in the above-mentioned conventional banknote holding device, the outer diameter of the wrinkle elongating roller 3 cannot be made too large, and there is a limit to increasing the insertion amount. Therefore, it is difficult to form a V-shaped deformation which is strong enough to prevent the banknote having a strong habit from returning to its original shape after being discharged without leaving a pressing scar. Further, in the above-described conventional banknote holding device, since the V-shaped deformation is formed at a time by the wrinkle straightening roller 3 arranged at the end of the transport mechanism, the rate of banknote damage is increased. Also, the release roller 1
Even when the banknotes are wrinkled by the cooperation of 1b, 12b, 13b, and 14b and the wrinkle-rolling roller 3, the wrinkles are likely to be insufficient because the wrinkles are only released at the discharge roller contact point B. The bill discharged from the discharge roller easily returns to its original shape.

Next, FIG. 5 shows a configuration of a conventional stack unit. A stack unit 40 is a substantially horizontal stack for stacking bills S sent from a transport mechanism 41 arranged on the upstream side in the bill transport direction on the upper surface. Table 42 and stack table 42
And a guide plate stopper 44 for restricting the amount of upward movement of the guide plate 43 and the like. Reference numeral 46,
Reference numeral 47 denotes a discharge roller pair which constitutes a part of the transport mechanism 41. The lower discharge roller 47 is provided with a sweeper 48 composed of elastic thin blades 48a extending radially from the center thereof. Is inserted between the stack table 42 and the guide plate 43. The bills S discharged from the nip portions of the two discharge rollers 46 and 47 onto the stack table 42 are pushed to the inner depth shown in FIG. The blade 48a that rotates together with the roller 47 presses the trailing edge of the discharged bill from above. FIG. 5B shows a case in which the number of banknotes S composed of habit tags stacked on the stack table 42 has increased to the near full state, and the guide plate 43 pushed up by the stacked banknotes is used as the guide plate stopper 44. When it rises to the extent that it comes into contact with the paper, the tip of the newly released bill abuts on the lower surface of the guide plate 44 and is restricted from entering the inner part, and the trailing edge of the bill rises along the lower surface of the guide plate. It will be easier. Since the trailing end of the raised banknote is close to the lower surface of the guide plate, it cannot be pressed down by the blade 48a, and the banknote is stacked while floating. If the trailing end of the stacked bills is raised, a subsequent bill collides with this portion and cannot enter the inner part, or may be bent.

To cope with such a problem, FIG.
As shown in (a), when the height of the stack table 42 is simply set low to expand the storage space, the stack table 42
Since the gap from the upper surface of the sheet to the guide plate 43 is wide, the habit tags discharged from the transport mechanism are less likely to be restricted by the guide plate 43, and return to the original shape and are easily rounded. Since the bill that has returned to its original shape is at a position where the trailing end of the bill cannot reach the blade 48a,
You cannot sit in a proper posture. For this reason, it collides with the following bills and breaks, causing a jam. Or,
When the storage space on the stack table 42 is enlarged by inclining the guide plate 43 at a steep angle as shown in FIG. 6B, in addition to the same problems as described with reference to FIG.
The leading end of the bill discharged from the transport mechanism 41 directly hits the lower surface of the guide plate 43 and is broken, possibly causing a jam.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. [Embodiment corresponding to first problem] FIGS. 1 (a) and 1 (b)
FIG. 2 is a front view and a side view of an example of the paper sheet holding device of the present invention for solving the first problem, and FIG. 2 is a plan view. This paper sheet holding device is applied to a bill dispensing device having a bill dispensing mechanism, such as a currency exchange machine, a cash depositing and dispensing machine, and a vending machine. When paying out a plurality of bills, the bills taken out one by one from the built-in safe are stacked in a holding device to form a bill bundle, and the bill bundles are collectively paid out to a user from a payout port. ing. The bill holding device as an example of the bill holding device of the present invention includes a transport mechanism 18 that transports rectangular paper such as the bill S one by one along the longitudinal direction of the bill S, Stack section 19 for receiving and temporarily stacking the discharged bills one by one
And a discharge mechanism 20 for discharging a bundle of bills at a time when a required number of bills are stacked on the stack section 19. The transport mechanism 18 is a vertical endless belt 2 that nips and transports the upper and lower surfaces of the central portion of the banknote S in the width direction.
Outer endless members 2, 23 and outer endless members which are arranged at positions respectively in contact with the lower surfaces of both end portions in the width direction of the bill S and push up both end portions in the width direction of the bill S higher than the height of the nip position by the upper and lower central endless belts 22, 23. Belts 24, 25
And Each endless belt 22, 23, 2
Reference numerals 4 and 25 denote flat belts.
6a, 27a, 28a, 29a, discharge rollers 26b, 2
It is stretched endlessly by 7b, 28b, 29b and driven to rotate in the direction of the arrow. The upper central endless belt 22 and the lower central endless belt 23 form a contact traveling area 30 that contacts the entire length in the transport direction,
This contact running area is defined by each outer endless belt 24, 25.
Is characterized in that it is set so as to gradually incline downward in the transport direction with respect to the movement trajectory of the upper running surface 31. In this embodiment, the diameter of the lower central discharge roller 27b is made smaller than the diameter of the upper central discharge roller 26b, and the position of the nip C between the two central discharge rollers 27b, 26b is set to the outer both outer discharge rollers 28b, 28b. 29b is set at a position lower than the upper surface.

On the other hand, upper and lower central introduction rollers 26a, 27
The height position of the nip portion D in FIG.
a, 29a are set substantially equal to the height position of the upper surface. For this reason, the bill S introduced into the transport mechanism from the direction of the arrow is nipped by the central endless belts 21 and 22 on the upper and lower surfaces in the width direction central portion, and is transported downstream in the contact traveling area 30. On the other hand, both ends in the width direction of the bill S are
The guide plates are supported without being nipped and supported on the upper running surface 31 of both outer endless belts 24 and 25 in a free state. At this time, the central endless belt 2
The moving trajectory of the contact traveling area 30 which is the nip portion of the first and second 22 is set so as to be inclined downward toward the downstream side in the transport direction with respect to the upper traveling surface 31 of both outer endless belts 24 and 25. , Introduction rollers 26a, 2
In the position 7a, the contact traveling area 30 and the upper traveling surface 3
Although there is a positional relationship with almost no step, the step is generated toward the downstream, and the step gradually increases. This step is a configuration for deforming the bill S conveyed while being nipped at the center in the width direction by the contact traveling area 30, and the V-shaped deformation is directed downstream from the introduction rollers 26 a and 27 b. The larger the step, the larger the step. In other words, the moving trajectory of the contact traveling area 30 of the central endless belts 21 and 22 gradually inclines downward with respect to the upper traveling surface 31 of both outer endless belts 24 and 25 that support the lower surface at both ends in the width direction of the bill. Therefore, the V-shaped deformation formed on the bill is gradually formed. Since both ends in the width direction of the bill S conveyed in this manner are not nipped, there is no risk of damaging the bill center even if the center in the width direction is pressed down and deformed. Even when a large V-shaped deformation that does not return is formed, the V-shaped deformation can be formed without leaving a scar on the bill. For this reason, even when a banknote having a strong habit is transported by the transport mechanism 18,
When this bill is discharged to the stack portion 19 located on the downstream side, it is corrected to a large V-shaped deformation state,
Problems such as returning to the original shape on the stack portion, resulting in poor stacking, and colliding with previously stacked banknotes do not occur. The illustrated discharge mechanism 20 is composed of upper and lower rubber rollers 35 and 36, and is driven to rotate while sandwiching the banknote bundle, thereby carrying the batch in the banknote payout direction. In this example, the lower rubber roller group 36 also serves as a stacking stand, and the required number of banknotes are deposited on the rubber roller group 36, and the upper rubber roller group 35
Is lowered, the bill bundle is sandwiched between the rubber rollers 35 and 36, and the bills are discharged by driving each. Symbol 37 is
It is a guide plate, and is a means for guiding to a proper position while suppressing a released habit tag.

[Embodiment Corresponding to Second Problem] Next, an embodiment of the present invention corresponding to the second problem will be described with reference to FIG. FIG. 3 is a main part configuration diagram of a bill holding device as an example of a paper sheet holding device. The bill holding device includes a transport mechanism 51 that transports the bills S one by one along the longitudinal direction of the bills, A stack unit 52 for receiving and temporarily stacking the bills discharged one by one from the mechanism 51, and a discharge mechanism (not shown) for collectively discharging a bundle of bills when a required number of bills are stacked on the stack unit 52; , Is provided. The stack section 52 includes a fixed stack table 53 for stacking banknotes on the upper surface, and a stack table 5.
And a guide plate 54 that is disposed opposite to the upper surface and rotates up and down under its own weight about a shaft 54 a and sandwiches the stacked banknotes with the stack table 53. The transport mechanism 51 includes discharge rollers 60 and 61 which nip in a vertical positional relationship. Blades 62 a protrude radially from the center of the lower discharge roller 61, and the blades 62 a constitute a sweeper 62. The characteristic configuration of the present invention is that the attitude of the stack table 53 is not horizontal, but the rear end of the stack table 53 is inclined downward by an appropriate angle θ with respect to the horizontal plane, for example, about 13 ± 3 °; The point is that the rear portion 54c is bent so that the rear portion 54c is inclined upward from the vicinity of the center in the longitudinal direction (see FIG. 1). This configuration is also shown in FIG.
By tilting the rear end of the stack table 53 downward in this manner, the rear end of the banknotes stacked on the stack table 53 is forcibly tilted downward. Even if the rear end part is slightly lifted, it is easy to avoid collision with the following bills discharged from the transport mechanism 51. In addition, as a result of the rear end of the habit tag on the stacking table being inclined downward, the guide plate 54 does not hinder the operation of the blade 62a for suppressing the rear end of the bill, and poor pushing into the bill and rising of the rear end are caused. Is prevented. Further, the rear portion 54b located substantially behind the center portion of the guide plate 54 is inclined upward by about 13 ± 3 ° with respect to the front portion 54b.
4c is in a state where it easily contacts the upper surface of the bill on the stack table, and even when a small number of bills are ejected on the stack table, the rear portion 54c suppresses the bill and suppresses return to the original form. Therefore, the conventional problem described with reference to FIG. 6 can be solved. Note that the rear end of the stack table 53 may be rotated vertically using the front end or the like of the stack table 53 as a rotation fulcrum so that the stack table 53 can be stopped at an arbitrary angle. With this configuration, it is possible to set an appropriate inclination angle for each device.

[0012]

As described above, according to the first aspect of the present invention, a transport mechanism for transporting paper sheets such as banknotes in the longitudinal direction thereof, and a stack for depositing the paper sheets discharged from the transport mechanism are provided. In the banknote holding device provided with the section, it is possible to reliably prevent the return of the original shape after discharging by transporting the paper sheet having a strong deformation habit while deforming it in a V-shape in the width direction. In other words, only the central part of the bill in the width direction is nipped by the upper and lower endless belts, and both ends in the width direction are transported by being pushed up by a large-diameter pulley, so that the bill is surely large and strong without damaging the bill. Deformations can be formed. A second invention of the present invention is a bill storage device including a transport mechanism for transporting paper sheets such as bills along the longitudinal direction thereof, and a stack unit for depositing the paper sheets discharged from the transport mechanism. It is possible to effectively prevent a stacking defect, which is a problem that occurs when stacking sheets having a deformation habit discharged from the transport mechanism on a stack table having a substantially horizontal upper surface. In other words, the stack table is inclined downward by a required angle to the downstream side in the transport direction from the horizontal attitude, so that a deposition failure or the like can be reliably prevented.
