Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper sheet storage device used in an automatic banknote dispensing apparatus having a mechanism for dispensing a plurality of banknotes in a stacked state. For example, banknotes inserted by a user are temporarily stored in a safe, and if necessary The present invention relates to a paper sheet storage device suitable for a reflux-type banknote dispensing device which is taken out from a safe and dispenses a required number of sheets.
[0002]
[Prior art]
Devices equipped with banknote dispensing mechanisms (hereinafter referred to as banknote dispensing devices) such as money changers, cash deposit / withdrawal machines, vending machines, etc., when taking out multiple banknotes, take out one by one from the built-in safe The banknotes are stacked in a holding device to form a banknote bundle, and the banknote bundle is batched out to the user from the payout port.
The banknote holding device receives a banknote transported from a safe or the like, and receives the banknotes sent from the transport mechanism located on the downstream side of the transport mechanism one by one and accumulates them on the stacking table. And a discharge mechanism that operates when a required number of paper sheets are stacked on the stack section and discharges the paper sheet bundle to the outside in a lump.
In addition to the type that stacks the banknotes that have been fed in on the stacking table, the stacking unit has a simple holding mechanism that allows it to be dropped and deposited on the stacking table. There is. The former type has the advantage that stacking defects on the stacking table are less likely to occur, but has the disadvantage that the configuration is complicated and large. On the other hand, the latter type of paper sheet storage device has an advantage that the configuration can be simplified, reduced in size, and reduced in thickness.
However, in the latter type of banknote holding device, when the banknote used for paying out is a tag with a hook such as a hook or a fold, there is no mechanism for sufficiently restricting the hook. After being transported while being restrained by the transport belt that constitutes, the bowl shape returns to its original shape when it is released onto the stacking table, causing a deposition failure or colliding with an already stacked banknote. The possibility of causing poor deposition increases.
For this reason, in the latter type of banknote holding device, when the transport mechanism transports the banknote along its longitudinal direction, it forms a V-shaped ridge in the width direction and conveys the heel. In addition, there has been proposed a banknote holding device in which a kneading roller is arranged in a transport mechanism.
[0003]
4 (a) and 4 (b) are a front view and a side view showing the main part (conveying mechanism) configuration of such a conventional banknote holding device, and the conveying mechanism is configured to move the banknote S along its longitudinal direction. It has outer endless belts 1 and 2 for conveying, and a ridge-stretching roller 3 positioned at the center of both outer endless belts 1 and 2. The outer endless belts 1 and 2 are composed of upper and lower endless belt pairs 11, 12, and 13, 14, respectively. The endless belt pairs 11, 12, and 13, 14 are introduced rollers 11a, 12a, 13a, 14a, respectively. And the discharge rollers 11b, 12b, 13b, and 14b, and are driven to rotate in the direction of the arrow. The dimensions of the endless belts 11, 12, 13, and 14 constituting the outer endless belts 11 and 12 are constant, and the diameters of the rollers that support the belts are also constant. Further, the outer endless belts 1 and 2 are opposed to each other as shown.
At the intermediate position between the upper endless belts 11 and 13, the stretching roller 3 is disposed coaxially with the discharge rollers 11b and 113b. The diameter of the stretching roller 3 is configured to be larger than the diameter of the discharge rollers 11b and 13b facing each other. For this reason, the spreader roller 3 can push down the center part of the banknote to be conveyed by the amount of insertion shown in FIG.
The banknote S introduced from the direction of arrow A in FIG. 4A along the longitudinal direction faces the downstream side while being nipped by the upper and lower belts 11, 12, 13, 14 at both ends in the width direction. When it is conveyed and reaches the positions of the discharge rollers 11b and 13b, it is pushed down by the outer peripheral edge (flange portion 3a) of the heel-stretching roller 3 and deformed into a substantially V shape. In this way, the bills are transported and discharged while being deformed into a V shape by the heel-stretching roller 3 located at the end of the transport mechanism, so that even a bill such as a bill or a folded bill is discharged from the transport mechanism. Since the V-shaped deformation remains when stacked on the stacking table 15, it can be prevented to some extent from returning to the original shape with ridges, thereby preventing poor deposition.
[0004]
However, in practice, a V-shaped deformation sufficient to prevent the banknotes S having a strong enough hook to cause a deposition failure on the stacking table from being returned to the original form after being discharged from the transport mechanism is formed. It was difficult to do with the conventional banknote holding device. That is, in the above-described conventional banknote holding device, both ends in the width direction of the banknote S are firmly niped by the upper and lower endless belts 11, 12, 13, and 14, and the center in the width direction is stretched by the stretching roller 3. If the banknote central part is pushed down forcibly, the mark and scars left by the flanged portion 3a of the roll-stretching roller remain in the banknote central part, causing damage to the banknote. For this reason, in the said conventional banknote holding | maintenance apparatus, the outer diameter of the spreading roller 3 cannot be enlarged too much, Therefore There was a limit in enlarging insertion amount. Therefore, it has been difficult to form a V-shaped deformation that is strong and large enough not to return to the original form after discharge without leaving a pressing scar on a banknote having a strong hook.
Moreover, in the said conventional banknote holding | maintenance apparatus, since the V-shaped deformation | transformation is formed at a time with the stretcher roller 3 arrange | positioned at the terminal part of a conveyance mechanism, the rate which a banknote is damaged becomes high. Even when the banknotes are stretched by the cooperation of the discharge rollers 11b, 12b, 13b, and 14b and the spreader roller 3, the spread of the bills is not possible because the spread is performed only at the discharge roller contact point B. The banknotes released from the discharge roller easily return to the original form.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
[Embodiment corresponding to the first problem]
1 (a) and 1 (b) are a front view and a side view of an example of a paper sheet storage device of the present invention for solving the first problem, and FIG. 2 is a plan view.
This paper sheet holding apparatus is applied to a banknote dispensing apparatus including a banknote dispensing mechanism such as a money changer, a cash depositing / dispensing machine, and a vending machine. When paying out a plurality of banknotes, the banknotes picked up one by one from the built-in safe are stacked in a holding device to form a banknote bundle, and the banknote bundle is batched out to the user from the payout opening. ing.
The banknote holding apparatus as an example of the paper sheet holding apparatus of the present invention includes a transport mechanism 18 that transports rectangular paper sheets such as banknotes S one by one along the longitudinal direction of the banknote S, and a transport mechanism 18. A stack unit 19 that receives and temporarily stacks banknotes discharged one by one, and a discharge mechanism 20 that discharges a banknote bundle collectively when a required number of banknotes are stacked on the stack unit 19 are provided.
The transport mechanism 18 is arranged at a position where the upper and lower central endless belts 22 and 23 that transport the paper sheet S by niping the upper and lower surfaces of the banknote S and the lower surfaces of both ends of the banknote S in the width direction are in contact with each other. Outer endless belts 24, 25 that push up both ends in the width direction of S higher than the height of the nip position by the upper and lower central endless belts 22, 23 are provided.
Each of the endless belts 22, 23, 24, 25 is a flat belt, and is stretched endlessly by introduction rollers 26a, 27a, 28a, 29a and discharge rollers 26b, 27b, 28b, 29b, and is driven to rotate in the direction of the arrow. Is done.
The upper central endless belt 22 and the lower central endless belt 23 form a contact traveling region 30 that is in contact with the entire length in the conveying direction. This contact traveling region is the upper traveling surface of each outer endless belt 24, 25. It is characteristic that it is set so as to be gradually inclined downward in the transport direction with respect to the 31 movement trajectory.
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 portion C of both the central discharge rollers 27b, 26b is set to the outer both outer discharge rollers 28b, It is set at a position lower than the upper surface of 29b.
[0010]
On the other hand, the height position of the nip portion D of the upper and lower central introduction rollers 26a, 27a is set to be substantially equal to the height position of the upper surfaces of the outer introduction rollers 28a, 29a.
For this reason, the banknote S introduced into the transport mechanism from the arrow direction is nipped on the upper and lower surfaces of the central portion in the width direction by the central endless belts 21 and 22 and transported downstream in the contact travel region 30. On the other hand, both end portions in the width direction of the banknote S are guided in a state of being supported on the upper running surfaces 31 of the outer endless belts 24 and 25 in a free state without being nipped. At this time, the movement trajectory 30 is such that the contact travel area 30 which is the nip portion of the central endless belts 21 and 22 is inclined downward toward the downstream side in the transport direction with respect to the upper travel surfaces 31 of the outer endless belts 24 and 25. Is set so that there is almost no step between the contact travel region 30 and the upper travel surface 31 at the positions of the introduction rollers 26a and 27a. Gradually increases. This step is a configuration for deforming the banknote S, which is conveyed while being nipped in the center in the width direction by the contact travel region 30, into a V shape, and the V shape deformation is directed downstream from the introduction rollers 26a and 27b. As the level difference increases, the size gradually increases. In other words, the movement trajectory of the contact travel region 30 of the central endless belts 21 and 22 gradually inclines downward with respect to the upper travel surfaces 31 of both outer endless belts 24 and 25 that support the lower surfaces of both ends in the width direction of the bill. Therefore, the V-shaped deformation formed on the banknote is gradually formed.
Since both end portions in the width direction of the bill S conveyed in this way are not nipped, there is no fear that the center portion of the bill will be damaged even if the center portion in the width direction is pressed down, and the original shape is increased by increasing the amount of insertion. 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 banknote.
For this reason, even when a banknote having a strong hook is transported by the transport mechanism 18, when the banknote is discharged to the stack portion 19 located on the downstream side, it is corrected to a large V-shaped deformation state. Thus, there is no problem such as returning to the original shape on the stack portion to cause poor deposition or colliding with banknotes deposited in advance.
Note that the illustrated discharge mechanism 20 is composed of upper and lower rubber roller groups 35 and 36, and is conveyed in a lump in the banknote dispensing direction by being rotationally driven with a banknote bundle interposed therebetween.
In this example, the lower rubber roller group 36 also serves as a stacking base. With the required number of banknotes deposited on the rubber roller group 36, the upper rubber roller group 35 is lowered and the rubber rollers 35, 36 move the banknotes. It is discharged by sandwiching the bundle and driving each one.
Reference numeral 37 denotes a guide plate, which is a means for guiding the guide plate to an appropriate position while suppressing the discharged tag.

This onset bright as above, a transport mechanism for transporting along a paper sheet such as a bill in the longitudinal direction, the banknote holding apparatus having a stack unit for depositing a sheet released from the conveying mechanism, By transporting paper sheets having strong deformed wrinkles while being deformed in a V shape in the width direction, it is possible to reliably prevent the original shape after being discharged. That is, only the central part in the width direction of the banknote is nipped by the upper and lower endless belts, and both ends in the width direction are conveyed by being pushed up by a large-diameter pulley. Variations can be formed .
