Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper sheet storage and release mechanism, and more particularly, to a paper sheet storage unit that temporarily stores paper sheets in an automatic paper handling machine such as an automatic cash handling apparatus (ATM) and then performs a discharging operation. The present invention relates to a storage / release device.
[0002]
[Prior art]
The paper sheet storage / release device of automatic machines such as an automatic cash handling device mainly uses a stacking type.
[0003]
However, in countries that use banknotes of almost the same size regardless of denomination and automatic machines that handle paper sheets of the same size, it can be used without problems with a stacking type storage / release device. In an automatic machine that handles papers of various sizes or countries or regions with significantly different sizes, the stacking type tends to be biased when stored, so it can not be released or it is easy to cause paper jams when released, A drum-type storage / discharge device that does not require re-separation during discharge must be used.
[0004]
Consists of a wheel that winds the belt and a take-up reel that rewinds the belt, and stores paper sheets conveyed between the belts wound on the wheel, and rewinds the belt to the take-up reel. An example of a banknote handling apparatus provided with a drum-type storage / discharge device for discharging banknotes is disclosed in JP-A-9-167273. In this bill processing apparatus, a small fold is returned to a folded bill, and a large fold is pressed to prevent clogging or tearing during conveyance.
[0005]
[Problems to be solved by the invention]
However, as in this conventional example, with a simple mechanism in which the drum is housed by being wound around a drum and is sent in a reverse direction, the drum is temporarily housed unless a plurality of storage / discharge devices are provided as in the case of the deposition type. It is not possible to return only abnormal tickets to customers among paper sheets.
[0006]
In addition, it does not take into account folding that occurs when paper sheets that have entered obliquely are wound around a drum. Furthermore, if the paper sheet is crushed, paper jams will occur when it is stored in a deposit-type safe that is separated for each denomination (kind) after the transaction with the customer, or when it is unloaded from this safe. It becomes easy.
[0007]
An object of the present invention is to provide an advantageous storage / discharge device capable of temporarily storing paper sheets of different sizes in a storage / discharge device and returning only abnormal tickets, and a paper sheet handling automatic machine equipped with the same. Is to provide.
[0009]
[Means for Solving the Problems]
The present invention relates to an entrance / exit, a discrimination device for discriminating paper sheets input from the entrance / exit, a temporary stacker for temporarily storing paper sheets discriminated by the discrimination device, and paper sheets for each type. In a paper sheet handling automatic machine equipped with a safe for storing and a conveyance path for conveying paper sheets between them, a belt is stretched between the first wheel and the second wheel, and either one of the two wheels. A drum type that winds up the belt to hold the paper sheet and stores the paper sheet, and discharges the paper sheet stored by winding the belt on the other of the two wheels. This is achieved by providing a temporary stacker for delivering only abnormal paper sheets to the entrance / exit by delivering paper sheets between the one wheel and the second wheel.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment in which the paper sheet storing and discharging apparatus of the present invention is used as a temporary stacker of an automatic cash handling apparatus (hereinafter also referred to as ATM) as an example of a paper sheet handling automatic machine will be described with reference to the drawings.
[0014]
FIG. 1 is a perspective view showing the overall configuration of a temporary stacker to which the present invention is applied. The first wheel 10 and the second wheel 20 are disposed at a position opposite to the main conveyance path (not shown) with the intermediate roller 30 in between. Then, the belt 40 is wound around the intermediate roller 30 so that the first wheel 10 and the second wheel 20 rotate in the same direction, and one end is directed to the first wheel 10 and the other end is directed to the second wheel 20. It is wound.
[0015]
Details of the overall configuration will be described with reference to FIGS. FIG. 2 is a cross-sectional view of the overall view shown in FIG. 1 cut at the center, and FIGS. 3 and 4 are perspective views showing a guide for explaining the details. In addition, in this specification, about the part which is the same structure in the 1st wheel 10 side and the 2nd wheel 20 side, only the 1st wheel 10 is demonstrated and the part name and code | symbol on the 2nd wheel 20 side are written in parentheses. It describes in. 3 and 4, only the first wheel 10 side is illustrated.
[0016]
The main conveyance path of ATM is constituted by the rollers 80 and 90 around which the conveyance belt 100 is hung, the nipping roller 60 in contact with the roller 80, and the nipping roller 70 in contact with the roller 90. Further, the swinging shaft 50 provided on the opposite side of the intermediate roller 30a from the first wheel 10 and the second wheel 20 and in the middle of the rollers 60 and 70, and the storage / release / abnormal note discharge mode are set. The temporary stacker is connected to the main transport path by rollers 80 and 90 provided with a switching gate 51 which is a branching means for switching and gate members 81 and 91 which are also branching means for mode switching.
[0017]
The belt 40 is moved from the vicinity of the intermediate roller 30b to the first wheel 10 (second wheel) so that the bill 220 to be carried in / out is guided to the first wheel 10 (second wheel 20) when stored and to the intermediate roller 30b when discharged. The bill guide 605 (615) is provided up to the vicinity of the position where it is wound by 20). The banknote guides 605 (615) are spaced at equal intervals in the axial direction of the first wheel 10 (second wheel 20) with the belt 40 as the center, preferably with a width that can guide the end of the smallest paper sheet. A spring 606 (616) is arranged so as to be always in contact with a part of the outer peripheral surface of the bill that is arranged and wound on the first wheel 10 (second wheel 20). An idle pulley 801 (811) is disposed on a swinging bracket 800 (810) that swings integrally with the shaft of the driven roller 31 (32) that is in contact with the roller 30a. is doing. In the present specification, the first wheel 10 (second wheel 20) side of the roller 30a may be referred to as the downstream side in the conveying direction of the belt 40 and the banknote 220.
[0018]
An elastic member 802 (812) is disposed at the tip of the swing bracket 800 (810), and is always in contact with the outer peripheral surface of the belt 40 wound around the first wheel 10 (second wheel 20). A gear 903 is further fixed to the shaft of the sandwiching roller 31 (32), and the gear 903 meshes with the gear 902. A plate-like member is fixed to the shaft of the gear 902, and an idle roller 900 is disposed at the tip of the plate-like member. The idle roller 900 is formed on the outer peripheral surface of the belt 40 wound around the first wheel 10 by the spring 901. It is configured to always touch.
[0019]
As the bills 220 are sequentially stored and the winding diameter of the first wheel 10 is increased, the swinging lever, gear 902, to which the idle pulley 900 is attached, rotates counterclockwise (counterclockwise). The moving bracket 800 rotates clockwise (clockwise). Even when the winding diameter of the first wheel is maximized, the idling roller 900 and a part of the banknote guide 605 are in contact with the outer peripheral surface of the belt 40 (and the banknote 220 composite). Since the banknote guide 605 regulates the out-of-plane deformation of the banknote 220, even if the banknote 220 to be carried in is a bad condition banknote such as a folded bag or a weak banknote, the banknote 220 can be stably stored. .
[0020]
In addition, an elastically deformable guide 700 (710) that regulates the out-of-plane deformation such as the folding of the bills is provided. Guides 700 (710) are arranged at positions spaced apart from each other at equal intervals in the axial direction of the first wheel 10 (second wheel 20) with the belt 40 as the center, and are guided by pulleys 703 that are rotatably supported by the shaft of the swing bracket 800. It is fixed. The pulley 703 is connected to a pulley 701 that is rotationally driven by a motor (not shown) via a timing belt 702. In addition, the guide 700 (710) is provided in accordance with the position where the end portion of a large banknote that is easy to bend is coming.
[0021]
When the folded edge 2200a is present at the leading end of the banknote 220a to be carried in, it is a problem because it is folded inward when it is wound around the wheel as it is, and the folded ear occurs. However, as a result of being wound around the wheel in a state where the out-of-plane deformation is restricted by the action and effect of the guide 700, the ear fold 2200a remains slightly deformed as shown by 2200b, but the ear fold does not occur.
[0022]
Furthermore, as shown in the perspective view of FIG. 4, in order to ensure the reliability of the storage / release device, the first wheel 10 (second wheel) is located from the vicinity of the winding position of the belt 40 of the first wheel 10 (second wheel 20). The second wheel 20) is wound around the first wheel 10 (second wheel 20) in the axial direction, preferably at a position where the banknote with the minimum width can be regulated in the same manner as the guide 605 (615). An elastic guide 602 (612) is provided for restricting out-of-plane deformation of the paper sheets stored with a narrower width than the belt 40. This elastic guide 602 (612) wraps a part of the outer peripheral surface of the banknote 220d wound around the first wheel 10 (second wheel 20), and changes the winding diameter of the first wheel 10 (second wheel 20). Following this, the length of contact with the outer peripheral surface of the banknote 220d is changed. By configuring the elastic guide 602 (612) in this way, even if the bill is skewed and entered like 220c, it is deformed out of plane when it is wound around the first wheel 10 (second wheel 20). Therefore, the corner portion can be stored and discharged without contacting the next banknote 220 and causing the ear fold.
[0023]
The elastic guide 602 (612) is hung on an idle pulley 601 that is rotatably supported on the shaft of the first wheel 10 (second wheel 20), and one end is on the banknote guide member 603 (613) on the wheel side and the other. The end is fixed to a spring 604 (614) via an idle pulley 601.
[0024]
The bill guide member 603 (613) is fixed to a small-diameter shaft that passes through a long hole indicated by a two-dot chain line provided on both side plates of a storage / discharge device (not shown), and both ends of the small-diameter shaft are fixed to a spring 607 (617). Has been. Therefore, the elastic guide 602 (612) changes the contact length while always contacting the outer peripheral surface of the banknote wound while following the change in the winding diameter of the first wheel 10 (second wheel 20). It will be. Even if the bill that has been skewed and carried in from the center is wound on the first wheel 10, even if the outer diameter of the outermost end is larger than the winding diameter of the belt 40, the first wheel 10 (second Since the outer peripheral surface of the banknote wound around the wheel 20) is regulated, it does not collide with the banknote subsequently carried in and does not collide with the ear.
[0025]
The structure of the drive part of the 1st wheel 10 (2nd wheel 20) by the motor 400 (410) is demonstrated to FIG. The gears 302, 310, 312 (305, 314, 317) are ordinary gears, and the gear 300 (303) has a built-in one-way clutch so as to transmit the driving force only when rotating in the direction of winding the belt. It is a gear. Reference numeral 311 (316) denotes a torque limiter.
[0026]
Gears 312 (317) and 310 (315) are arranged at both ends of the main connecting shaft 313 (314) via the torque limiter 311 (316), and the gear 312 (317) side and the motor 400 (410) are also connected. The 310 (315) side and the shaft 11 of the first wheel 10 (the shaft 21 of the second wheel 20) are connected to each other. Further, a slave coupling shaft 301 (304) is arranged in which torque driven by the gear 312 (317) is transmitted only in one direction, bypassing the torque limiter 311 (316). A gear 302 (305) that rotates integrally with the slave connection shaft 301 (304) and a gear 300 (303) with a built-in one-way clutch are disposed. The gear 302 (305) and the gear 300 (303) are connected to the main connection shaft 301 (304). The shaft gear 312 (317) and the gear 310 (315) are configured to mesh with each other.
[0027]
When the first wheel 10 rotates in the direction in which the belt 40 is wound, the driving force of the motor 400 is transmitted to the gears 312, 302, 300, 310 and connected to the shaft 11 of the first wheel 10. The
[0028]
On the other hand, since the second wheel 20 rotates in the direction in which the belt 40 is rewound at that time, the gear 303 is idled and is driven by the motor 410 via the torque limiter 316.
[0029]
When the first wheel 10 rotates in the direction to rewind the belt 40, the second wheel is directly driven by the motor 410, and the first wheel 10 is driven by the motor 400 via the torque limiter 311 with the gear 300 idling. .
[0030]
As a result, constant tension based on the set torque of the torque limiter 311 or 316 always acts on the belt 40, so that stable winding and rewinding can be performed.
[0031]
Also, a knob 401 (411) with a built-in one-way clutch is arranged at the shaft end of the motor 400 (410) in such a direction that the first wheel 10 (second wheel 20) can be manually rotated only in the direction of winding the belt 40. Has been. Therefore, it is possible to prevent the belt 40 from being rotated in a loosening direction due to an erroneous operation during maintenance, and thus it is possible to prevent the belt 40 from being detached from the first wheel 10 and the second wheel 20.
[0032]
FIG. 6 shows the state of the elastic guide 602 when the maximum amount of banknotes is stored in the first wheel 10. It can be seen that the spring 604 extends as much as the contact length of the elastic guide 602 is increased as compared to the state of FIG.
[0033]
Next, the operation of the present mechanism will be described with reference to FIGS. ◆
FIG. 2 shows a state of the banknote depositing counting mode, in which the belt 40 is wound around the second wheel 20. The switching gate 51 and the gate members 81 and 91 are held in a state where the banknotes conveyed from the upper side are branched and conveyed to the temporary stacker side. During work, the first wheel 10 and the second wheel 20 are driven counterclockwise (counterclockwise), and the speed is controlled so that the speed of the belt 40 is equal to the bill conveyance speed.
[0034]
When the mixed banknote 220 of 1,000 yen, 5,000 yen, and 10,000 yen bills deposited in the ATM is conveyed via a discrimination device (not shown), the roller pairs 30a and 31 and the idle pulley 801, as indicated by arrows, A normal ticket (a banknote that can be identified by a discrimination device) and an abnormal ticket (a banknote (RJ) that cannot be identified by a discrimination device) or a banknote that can be identified but is not used for recirculation on the first wheel 10 ) Are wound together with the belt 40 and stored in the first wheel 10. The order of banknotes at this time and the corresponding denomination, normal ticket, and abnormal ticket information are stored in the aforementioned discrimination device.
[0035]
The banknote discharge operation is performed by driving the first wheel 10 in the direction opposite to that in FIG. There are two types of discharge operation: an operation of discharging only abnormal bills to the main transport path and an operation of discharging all banknotes stored in the first wheel 10 (second wheel 20).
[0036]
Prior to this discharging operation, the pulley 701 needs to be rotated counterclockwise (counterclockwise) in order to prevent interference between the leading edge of the banknote to be discharged and the guide 700. When the storage operation is completed, the guide 700 is in a position substantially parallel to the bill loading / unloading direction (see FIG. 2). When the pulley 701 is rotated, the guide 700 is elastically deformed so as to get over the outer peripheral portion of the first wheel 10 having the maximum diameter, and the banknote can be discharged by completely retracting from the banknote loading / unloading surface. Become.
[0037]
Moreover, since the elastic member 802 arranged at the tip of the swing bracket 800 rolls the bills wound up as a scraper one by one, the tip of the released bills is smoothly guided in the carry-out direction, so that stable discharge operation Can guarantee.
[0038]
Further, the swing bracket 800 is configured to swing following the change of the swing angle of the swing lever, so that the bill formed by the idle pulley 801 and the belt 40 disposed at the tip of the swing bracket 800 is used. The distance from the pinching point of the first wheel 10 to the pinching point of the banknote formed by the wound belt 40 is substantially constant regardless of a change in the winding diameter of the first wheel 10 and is set to a small value. be able to. Therefore, even when a small-size banknote is loaded and unloaded, it can be reliably pinched and transported without generating an unstabilized unstable state, so that the reliability of the entire mechanism can be ensured.
[0039]
FIG. 6 shows a return mode in which only banknote deposit abnormal tickets are discharged to the main transport path. The gate members 81 and 91 are held in the state shown in FIG. 6, and the switching gate 51 is based on the above-described discrimination information. To switch between the solid line and the two-dot chain line. Both the first wheel 10 and the second wheel 20 are driven to rotate clockwise (clockwise), and the banknotes stored in the first wheel 10 are discharged. At this time, only the abnormal ticket is transported to the main transport path by the action of the switching gate 51, and is returned to the customer via an ATM withdrawal port (not shown). On the other hand, the normal ticket is stored in the second wheel 20.
[0040]
FIG. 7 shows the operation in the deposit storage mode in which all the stored banknotes are discharged and deposited in the safe. The switching gate 51 and the gate members 81 and 91 are held in the state shown in FIG. The belt 40 is shown as a solid line when it is completely wound on the wheel, and conversely when it is completely rewound as a two-dot chain line, and represents a change in the wheel diameter depending on the winding amount of the belt 40. The first wheel 10 and the second wheel 20 are again driven counterclockwise (counterclockwise), and the normal ticket released from the second wheel 20 is transported to the main transport path as shown by an arrow, not shown. It is stored in a dedicated money box and the operation is completed.
[0041]
Finally, an embodiment in which the storage / release device of the present invention is applied to an automatic teller machine (ATM) will be described with reference to FIGS. FIG. 8 shows an example of a banknote handling mechanism 501 mounted on an ATM. The banknote storage / release mechanism (hereinafter referred to as a temporary stacker) 560 according to the present invention, which has been described in detail above, and a gold having the same configuration as this temporary stacker. A seed storage / recycle box 561 is installed. Deposited banknotes input from the customer are temporarily stored in the first wheel of the temporary stacker 560 via the discrimination device 520 as described above in a mixed denomination. At this time, if there is no detection of a deposit abnormality ticket (hereinafter referred to as deposit RJ) by the discrimination device 520, the automatically counted amount is confirmed by the customer, and after the deposit transaction is established, it is released as it is from the first wheel 10. At this time, the order and denominations of the banknotes to be released are stored in the discrimination device 520, and are distributed to each denomination dedicated box 540 via the entire conveyance path 530 according to the information, and the deposit transaction is completed.
[0042]
On the other hand, when the deposit RJ is detected by the discrimination device 520 at the stage of being temporarily stored in the first wheel, the normal ticket is stored in the second wheel as described with reference to FIGS. It is returned to the deposit / withdrawal port 510 via the transport path 530. At this time, in consideration of the length of the storage belt that matches the number of deposits RJ, the belt of the first wheel is rewinded with sufficient margin, and the second wheel is controlled to wind up the belt of that excess length. Is done. The bills returned to the deposit / withdrawal port 510 are then separated again from the deposit / withdrawal port 510 and stored in the first wheel 10 via the discrimination device 520, but the normal bill is released from the second wheel 20 by the control. Never happen. At this time, if the deposit RJ is not detected, the deposit transaction is established. After the release from the first wheel 10, the deposit transaction is also released from the second wheel 20 and the deposit transaction is completed as described above.
[0043]
If the deposit RJ is detected even at this stage, the same routine is repeated until the deposit RJ is canceled so that only the normal ticket is stored in the second wheel 20 again and the deposit RJ is returned to the deposit / withdrawal port 510. It is. Of the normal tickets that have been deposited, the denominations to be reused as withdrawal banknotes are stored in the respective denomination depots 540, and other denominations and non-reflux tickets are stored in the deposit cassette 550.
[0044]
The recycle box 561 having the same configuration as that of the temporary stacker 560 has the following first function. The received normal ticket is stored in the first wheel 10 by denomination mixing. And it discharges | emits from the 1st wheel 10 at the time of payment | withdrawal transaction, and withdraws only the required denomination directly to the deposit / withdrawal port 510 via the whole conveyance path 530. At this time, other denominations are stored in the second wheel 20. Thereafter, it may be discharged from the second wheel 20 and stored in the first wheel 10 and operated again as described above, or may be discharged directly from the second wheel 20.
[0045]
An example will be described in which the recycle box 561 described with reference to FIG. 9 is used as a simple deposit-only box for two denominations (for example, a 10,000 yen ticket and a thousand yen ticket). 9 indicates that only the belt 40 is wound. First, both the first and second wheels are initially set so that the amount of winding of the belt 40 is approximately halved (a). Next, the 10,000 yen coupon is separated from the dedicated safe 540 shown in FIG. 8, and the number of storable sheets is stored in the first wheel via the entire conveyance path 530 and the identification device 520 (b). Then, all 10,000 yen tickets are released from the first wheel and stored in the second wheel (c). Next, the belt of the first wheel is wound around the second wheel to complete the preparation for storing the thousand yen ticket (d). A thousand yen ticket is separated from the dedicated safe 540 in FIG. 8, and the number of storable sheets is stored in the first wheel via the entire conveyance path 530 and the identification device 520 (e).
[0046]
In this state, a thousand yen ticket is stored on the first wheel, and a 10,000 yen ticket is stored on the second wheel. Both the 10,000 yen ticket and the thousand yen ticket can be released, and a withdrawal request can be immediately responded.
[0047]
In addition, the deposited 10,000 yen ticket and thousand yen ticket are stored in the first wheel, the 10,000 yen ticket is discharged as it is withdrawn, and the thousand yen ticket is temporarily stored in the second wheel. Also, operation with a recycling function that uses the deposited banknote as a withdrawal banknote is possible.
[0048]
The present invention is not limited to the embodiments described above, and includes various operations that can be considered as long as both the first and second wheels are operated so that bills can be stored and discharged. .
[0049]
【The invention's effect】
As described above, the present invention has the following effects.
[0050]
Because it is a drum type, even paper sheets of various sizes can be stored and discharged, and paper sheets can be exchanged between multiple wheels. It is possible to realize a multi-functional banknote storage and release mechanism that can be used for the operation of discharging the stored normal bills and depositing and storing them in a dedicated cashbox after the payment transaction is completed.
[0051]
In addition, by providing a guide that suppresses out-of-plane deformation during winding and after winding, even skewed paper sheets can be wound and stored without being folded or jammed. Further, by providing an ear breakage regulation guide, it is possible to store after correcting some ear breakage.
