Detailed description of the invention

[Technical field to which the invention pertains]

This invention is used by being incorporated into a banknote processing device, especially an automatic vending machine, an automatic ticket vending machine, an automatic money changer, etc., and after distinguishing the inserted banknotes, stacking them and storing them according to denomination, and storing them in a stack according to a specific denomination based on a command, For example, the present invention relates to a device for dispensing 1,000 yen bills as change or small bills to be exchanged.

[Prior art and its problems]

Recently, the products handled by vending machines have become increasingly expensive, and the prices of tickets sold by automatic ticket vending machines, for example, have become higher, so there are cases where payment is made in 10,000 yen or 5,000 yen bills. It's getting more and more. Therefore, it became necessary to use hard change such as 1,000 yen bills. In the past, in most cases, all change was given in hard form, so if the payment was in 10,000 yen or 5,000 yen bills, it was often not accepted, and even if it was accepted, it was too expensive for the customer. Not only was it time consuming, but it was also very inconvenient. Therefore, in the case of paying with high-value banknotes as mentioned above, either have a 1,000 yen bill exchanged at a manned counter, or exchange a 10,000 yen bill or 50,000 yen bill.
They used a simple automatic exchange machine attached to the facility to exchange 1,000 yen bills for 1,000 yen bills. Also, when dispensing multiple 1,000 yen bills as change as described above, instead of preparing 1,000 yen bills exclusively for dispensing, it would be better to store the inserted 1,000 yen bills in a stack and then use them for dispensing. It's convenient. In other words, 1,000 yen banknotes will be recycled. This recycling of banknotes has already been carried out in automatic deposit and payment machines for banks for three or four years. Here, the range was expanded to include all denominations of banknotes for recycling. However, the device was quite large and the cost was quite high. Therefore, we have developed a banknote processing device that can be incorporated into automatic vending machines, automatic ticket vending machines, and simple currency exchange machines that handle general high-value products and tickets, that is, to distinguish, store, and dispense the input banknotes.In particular, the payout is based on the recycling of 1,000 yen banknotes.
As the market needs for equipment that performs this are increasing, there is a strong demand for high reliability, low cost, and miniaturization. Moreover, the even stricter technical condition lies in the aspect of payout. In conventional money exchange or payment machines, the bills to be dispensed are arranged and stored in a predetermined position by a person. On the other hand, in this banknote processing device, the banknotes paid (inserted) by a person are mechanically stacked and stored, so the orderliness of the storage is inevitably worse than when the banknotes are stored manually. As mentioned above, we have developed a banknote processing device that stores the three denominations of 10,000 yen bills, 5,000 yen bills, and 1,000 yen bills, and allows 1,000 yen bills to be used for dispensing. Market needs have been particularly high recently. However, full-scale widespread use will not be possible unless the issues of high reliability, low cost, and miniaturization are solved.

[Purpose of the invention]

The purpose of this invention is to solve the problems of the conventional ones, to classify and store the inserted banknotes of multiple denominations, and to store 1,000 yen banknotes of one denomination in accordance with the directive. It is an object of the present invention to provide a banknote processing device which can be used for dispensing from stored items, is highly reliable, is low cost, and is miniaturized.

[Key points of the invention]

The main points of the present invention to achieve the above objects are as follows:
It has the following configuration. The banknote storage areas are arranged adjacent to each other in substantially the same direction as the stacking direction of the banknotes, and the banknotes are sequentially dispensed from the outermost stored banknotes of the endmost storage area, for example, from the top banknote surface. Let it roll out. A banknote discrimination mechanism is provided that determines the denomination and authenticity of the banknote and then allows the banknote to pass or is returned under predetermined conditions. Further, a banknote storage gate mechanism is provided for each denomination, which switches the transport of banknotes from the banknote discrimination mechanism to the storage direction based on a command and reliably feeds the banknotes to the next stage storage mechanism. The edges of one side of the banknote sent through the banknote storage gate mechanism in a direction perpendicular to the conveyance direction are received by a rotating guide plate, and the middle part of the other side of the banknote is received by a conveyance belt, so that the banknote is stored. Each banknote storage mechanism is installed by curving a cross section in a direction perpendicular to the conveyance direction, and storing banknotes in a stacked manner by rotating a rotation guide plate at a banknote storage position so as to flip up both side edges of banknotes and then returning the plate to its original position. . The banknote storage bottom plate is positioned by raising and lowering the banknote storage bottom plate so that the contact pressure between the conveyor belt of the banknote storage mechanism and the surface of stored banknotes is weak and strong, respectively, based on the storage command and the dispensing command. The elevating mechanism is provided only in the banknote storage mechanism for dispensing. Furthermore, only for the bill storage mechanism for dispensing,
A banknote feeding mechanism is provided which sequentially feeds out stored banknotes one by one starting from the topmost banknote based on a payout command. In addition, only for this bill storage mechanism for dispensing, based on the storage command, the bill to be stored is blocked in a predetermined position, and this blocking is released based on the dispensing command. A banknote position regulating member is provided for pushing back banknotes that have not been removed to their original predetermined positions. Among the bills sent out from the bill dispensing mechanism, there is a take-out bill accommodating mechanism that temporarily stores the bills sent out in a normal state and opens the ejection port based on a command, and a take-out bill storage mechanism that temporarily stores the bills sent out in a normal state. A banknote temporary storage mechanism is provided in which a reject banknote storage case is temporarily stored as a reject banknote, and a switching member is configured to selectively switch a conveyance path to the removed banknote side and the reject banknote side.

[Embodiments of the invention]

An embodiment of the invention will be described with reference to the drawings. First, the entire structure of the embodiment apparatus will be schematically explained using a side view of FIG. 1 showing the arrangement of the main mechanical parts. 50 is a banknote discrimination mechanism, 20A, 20B, 20C
are respectively a 1,000 yen bill storage area, a 10,000 yen bill storage area, and a 5,000 yen bill storage area; 40 is a banknote feeding mechanism;
Reference numeral 60 indicates a takeout bill storage mechanism, 81 indicates a reject bill storage case, and 90 indicates a power source storage section. Each of the bill storage locations 20A, 20B, and 20C has a common bill storage mechanism 20, and only 10,000 yen bills as payout bills, other 10,000 yen bills, 5
There is a banknote storage bottom plate that is different from that for 1,000 yen banknotes. This banknote storage bottom plate portion will be described later. There are the following mechanical parts or members that serve to connect the respective mechanical parts. Banknote discrimination mechanism 50 and each banknote storage location 20A, 2
A banknote storage gate mechanism 19 between 0B and 20C,
There are a bill pressing roller 19a and a bill guide plate 19b. This is to switch the conveyance path for sending the banknotes sent from the banknote validating mechanism 50 to the respective banknote storage locations according to the type thereof. The banknote storage gate mechanism 19 switches the sent banknotes either in the direction of each banknote storage location 20A, 20B or straight ahead to the next banknote storage location. On the other hand, the banknote pressing roller 19a, together with the guide plate 19b, has a fixed gate function only for the 5,000 yen banknote storage area. In addition, each banknote storage space 20A, 20B, 20C
A feed roller 28 is provided to connect the banknote inlets. Next, a bill position regulating lever 26 is provided between the thousand yen bill storage space 20A and the bill feeding mechanism 40 that feeds out the thousand yen bills stored therein. This banknote position regulating lever 26 is used to block new banknotes in order to position them at a predetermined position when storing them, and to rotate clockwise around a predetermined axis to dispose new banknotes. The blocking state is released, and after the bill dispensing operation is completed, the bill returns to the counterclockwise direction and serves to push the bills remaining in the bill dispensing mechanism section 40 back to the original predetermined storage position. Here, regarding the banknote storage bottom plate that I have already mentioned,
Let's be specific. In the 1,000 yen bill storage area 20A,
When storing and dispensing new banknotes,
A bottom plate elevating mechanism 30 is provided at the lower part of the 1,000 yen banknote storage mechanism 20 in order to raise and lower the stored banknotes to different positions and to ensure each operation. 20 storage spaces for other 10,000 yen bills and 5,000 yen bills
B and 20C are provided with a bottom plate portion having a simple structure with a leaf spring 98 provided on the lower surface. This is because only banknotes are stored here. Further, between the banknote feeding mechanism 40, the removed banknote storage mechanism 60, and the reject banknote storage case 81, there are provided a feed roller 91 as a banknote conveyance path, a conveyance belt 96, etc., and the removed banknote storage mechanism 60 and the reject banknote storage case. A switching member 16 for switching the conveyance direction to each of the 81 is provided. The configuration is outlined above. Next, the operation of this embodiment device will be described based on FIG. 1 as well. A bill inputted into the bill validating mechanism 50 from the I direction is normally conveyed out in the P direction after its authenticity and denomination are determined in this mechanism. If certain conditions are met, such as if the banknotes are not recognized as genuine or if the customer withdraws his or her intention to make a transaction, the banknotes will be returned. In other words, it will be thrown out in the opposite direction to where it was thrown. Now, the banknotes carried out in the direction of arrow P from the banknote validating mechanism 50 are sent to the banknote storage location corresponding to the denomination of the banknote. This is performed by the switching operation of the gate mechanism 19. That is, for example, in the case of a thousand yen bill, the bill storage mechanism 2
The banknote storage gate mechanism 19 belonging to 0A moves to the position indicated by the solid line as shown in the figure, the conveyance path is switched in the direction of arrow J1, and the banknote storage gate mechanism 19 is stored in the banknote storage mechanism 20. Conversely, if it is not a 1,000 yen bill, the bill storage gate mechanism 19 moves to the two-dot-dashed line position and continues to P.
It will be transported in the same direction and proceed to the next storage location. Note that when a thousand yen bill is stored, the bill position regulating lever 26 is in the position shown in the figure, and functions to block the transported bill and determine the bill storage position. Similarly, in the case of 10,000 yen banknotes, storage space 20B
The banknote storage gate mechanism 19 belonging to the banknotes operates to the position indicated by the solid line based on the denomination signal, and the banknotes are switched and stored in the J2 direction. In this case as well, the banknote storage position is determined by another blocking portion shown. However, in the case of a 5,000 yen bill, since it is the final bill, there is no need to change the conveyance path, and it is conveyed and stored in the direction of arrow J3. Note that the feed rollers 28 installed between the banknote storage mechanisms 20 have the function of ensuring banknote conveyance between them. The function of the bottom plate section for stacking and storing banknotes differs only for 1,000 yen banknotes from that for other banknotes. That is, in the case of a thousand yen bill, when storing the banknote, the bottom plate is adjusted up and down and positioned so that the surface of the stored banknote does not come into strong contact with the conveyance belt of the storage mechanism. When the banknotes are fed out for dispensing, the banknotes are adjusted and positioned so that the surface of the stored banknotes is in strong contact with the conveyor belt. By changing the contact state of the surface of the stored banknotes with the conveyor belt as described above, the banknote storage operation and the banknote feeding operation are reliably performed. The function of the bottom plate portion of the 10,000 yen bill and the 5,000 yen bill is to bring the banknotes into weak contact with the conveyor belt on the surface of the stored banknotes by means of a leaf spring 98 provided below. This is because in this case, the banknotes are simply stored in a stack. The reason why the storage area for 10,000 yen bills is provided above that for 5,000 yen bills is to shorten the transport distance as much as possible since 10,000 yen bills are in circulation more often. This concludes the explanation of how three denominations of banknotes are classified and stacked and stored. Next, the operation of dispensing 1,000 yen bills based on the dispensing command will be described. As described above, when a payout command is issued, the bottom plate elevating mechanism 330 is first activated and positioned so as to strengthen the contact pressure between the conveyor belt of the storage mechanism and the surface of the stored banknotes. Next, the banknote position regulating lever 26 is rotated counterclockwise to release the banknote blocking, and the banknote feeding mechanism 40 is operated to feed out the banknotes one by one in the direction of the forward arrow L. The banknotes sent out in this way are sent to the delivery roller 9.
1. Sent downward by a conveyor belt 96 etc.
The banknotes are stored in the removed banknote storage case belonging to the removed banknote storage mechanism 60 in the direction of arrow M, or in the reject banknote storage case 81 in the direction of arrow N. Here, the ejecting mechanism is used when the delivered banknotes are in a normal state, and the customer may take them out as they are. On the other hand, a rejected banknote is one in which the sent banknote is in an irregular state.
For example, if multiple bills overlap for some reason, or bills that should come out at a predetermined interval come out at less intervals, in short, it is possible to redetect the denomination and number of bills to be dispensed. This refers to banknotes that have been sent out in a state that cannot be handled properly. Such banknotes are accommodated as reject banknotes in another case, that is, the reject banknote storage case 81, and are collected later. Of course, the banknotes for payout will have to be sent out again. Note that switching between the ejection mechanism storage case and the rigid banknote storage case 84 is performed by the switching member 76 that operates based on the banknote detection signal. Reference numeral 77 denotes a guide member whose function is to ensure that reject banknotes are inserted into the storage case 81. The mechanism for accommodating the above two types of banknotes will be collectively referred to as a banknote temporary storage mechanism 80. Having explained the basic structure and operation of the embodiment device above, the main mechanical parts will now be described in more detail based on respective perspective views. FIG. 2 is a perspective view showing the bill validating mechanism. The banknote discrimination function section is omitted and the banknote transport path is mainly illustrated. The banknote validating mechanism 50 is roughly divided into an upper validating section above the banknote transport path and a lower validating section below. Hereinafter, each component will be explained along the flow of power transmission for bill conveyance. Power from a power source (not shown) first enters the shaft 51 via the belt pulley 51D. This shaft 51 belongs to the lower discrimination section 50L. The power entering the shaft 51 is transferred to the belt pulley 5 attached to the other shaft end.
1E to the shafts 52, 53 via the belt pulleys 52E, 53E and toothed belts hooked thereto.
transmitted to. Further, belt pulleys 53D and 53F attached to the shaft 53, and a belt pulley 54
Axes 54, 55, 56 via D, 55D, 56D
Power is transmitted to both, and both are rotated in the direction of the arrow shown. The above axes 52, 53, 54, 55,
56 both belong to the lower discrimination section 50L. Conveying rollers 51A, 51B, 51C, 52A, 5 are provided on the shafts 51, 52, 54, 55, 56, respectively.
2B, 52C;... are attached. A pressing roller is provided in opposing contact with each of the above-mentioned conveying rollers. The reference number for this holding roller is the same as the reference number for the conveyance roller, with lowercase letters added instead of uppercase letters. For example, the conveyance roller 51
The reference numeral 51a is the pressure roller that is in opposing contact with A. All of these pressing rollers are in the upper discrimination section 5.
It is installed in 0U. However, there is no pressing roller that comes into contact with the conveying roller of the shaft 56,
A banknote sensor (not shown) is provided at approximately the same position. With the above configuration, when a banknote is inserted from the direction of arrow I, the banknote is placed between the conveyance rollers 52A, 52B, 52C provided on the shaft 52 and the press rollers 52a, 52b, 52c that are in opposing contact with the conveyance rollers 52A, 52B, 52C. Being pinched and transported. Similarly, the shafts 54, 5
The banknotes are conveyed in the I direction by the conveyance rollers attached to the banknotes 5 and 51, respectively, and the press rollers in contact with the conveyance rollers, and along the way, the authenticity and denomination of the banknotes are determined by various banknote sensors (not shown). . Then, in the normal case, it is carried out in the direction of arrow P and moves on to the next stage. If it is determined that the bill is not genuine or if the customer withdraws his or her intention to make a transaction, this mechanism performs a return operation and the bill is conveyed in the opposite direction of arrow I and returned to its original insertion slot. Next, when the banknote carried out from the banknote discrimination mechanism 50 is a 1,000 yen banknote, this banknote is transferred to the banknote storage mechanism 2.
0, and how it is delivered via the delivery mechanism 40 for dispensing based on a command.
The explanation will be given with reference to a perspective view showing the related mechanical parts in a diffusely exploded manner. In FIG. 3, the banknote storage gate mechanism 19, a banknote storage mechanism 20, a banknote position regulation lever 26, a banknote storage bottom plate elevating mechanism 30, and a banknote feeding mechanism 40 are schematically shown. The general structure and operation of the above main elemental mechanisms will be described below. The banknotes 10 carried in from the direction of arrow P are turned to the storage side by the direction change guide rail 11 of the banknote storage gate mechanism 19, and the banknotes 10 are transferred to the storage side by the belt 5 and the press roller 12 provided at the end of the direction change guide rail 11.
The banknotes are conveyed to the banknote storage mechanism 20 by being sandwiched between them. In the banknote storage mechanism 20, the banknotes 10 are stored between the belt pulleys 2 and 3 of the conveyor belt 5 and the rotation guide plate 2.
2, and its movement is prevented by the banknote position regulating lever 26. This blocked position is the storage position. Next, the rotation guide plate 22 rotates approximately 1/4 around the shaft 23, flipping up both side edges of the banknote 10 and dropping the banknote 10 onto the underside of the conveyor belt 5 between the belt pulleys 2 and 3. . In this way, a new layering on the surface of the already stored banknotes 10A has been performed. In order to smoothly stack the banknotes 10 on the surface of the stored banknotes 10A as described above, the banknote storage bottom plate elevating mechanism 30 functions. That is, a support post 31 provided on the bottom plate 25 is guided and supported by guide rollers 32 so as to be movable in the vertical direction, and a rack 33 is attached to this support post 31. A pinion 34 is meshed with this rack 33, and this pinion 34 is further connected to a motor 37 via gears 36A and 36B. Based on the banknote storage command, the motor 37 first rotates to raise the bottom plate 25, comes into contact with the conveyor belt 5 of the banknote storage mechanism 20, stops once, and immediately thereafter rotates slightly in reverse again. Due to this operation, the contact pressure between the surface of the stored banknotes 10A and the conveyor belt 5 becomes very small or zero. Zero means that there is no contact between the two.
The former case occurs when there are many stored banknotes, and the latter case occurs when there are few. Under such a contact pressure state, the banknotes 10 can be transported for storage smoothly. Next, the banknote feeding mechanism 40 is connected to the banknote storage mechanism 20.
It is installed in such a way that it fits into a part of the In other words, the bill feeding roller 42 is located above the leading end of the bill 10 in the storage position. Reference numerals 43 and 44 refer to a set of rollers for preventing the passage of multiple bills, each having the function of allowing only one bill to pass between them. The banknote feeding roller 42 and multiple sheet passage prevention rollers 43, 44 are rotated by the drive shaft 41 in the direction of the arrow via belt pulleys 45A, 45B and toothed belt 45C. Bill feeding roller 42, multiple bill passage prevention roller 4
A holding frame 49 that holds together the parts 3 and 44 is rotatably installed around a rotation shaft 41. In addition, this holding frame 4
9 is provided with an electromagnetic actuator 46, a spring 47, and a push shaft 48. When a bill payout command is issued, first, the bill storage bottom plate elevating mechanism 30 is activated, the bottom plate 25 rises, and stops with the surface of the stored bill 10A in strong contact with the conveyor belt 5. Next, the electromagnetic actuator 46 operates to rotate the holding frame 49 clockwise to move the outer circumferential surface of the banknote feeding roller 42 to the stored banknotes 10.
Press it onto the surface of A. At the same time, holding frame 4
A push shaft 48 provided at the banknote 9 pushes one end of the banknote position regulating lever 26 and rotates it clockwise to release the blocked state of the front end surface of the stored banknote 10A. In this state, the bill dispensing roller 42 rotates a number of times corresponding to the predetermined number of bills, and the stored bills 10A are dispensed in order from the top in the direction of the arrow Q by the frictional force of the rubber unevenness provided on the outer periphery. Furthermore, one of the banknotes 10 is
Only one piece is allowed to pass. When a predetermined number of sheets have been fed out, the electromagnetic actuator 46 is turned off based on a command, and the holding frame 49 is rotated counterclockwise by the spring 47.
In this way, the outer circumferential surface of the banknote feeding roller 42 separates from the surface of the stored banknote 10A. At the same time, the banknote position regulation lever 26 is released from the push shaft 48,
It is rotated counterclockwise by the spring 28 and returns to the original bill blocking position. During the return operation process of this banknote position regulating lever, if multiple sheets pass prevention roller 43,
If there are banknotes stuck at 44, the banknotes are pushed back to their normal storage positions, that is, their positions are adjusted. Next, each banknote storage mechanism 20 and storage bottom plate section will be described based on the perspective view of FIG. 4 when the banknotes discharged from the banknote discrimination mechanism 50 are 10,000 yen banknotes or 5,000 yen banknotes. The banknote storage gate mechanism 19 and the banknote storage mechanism 20 are almost the same as those for the 1,000 yen banknote. "Almost"
This means that in the case of a 5,000 yen bill at the bottom, the direction change guide rail of the bill storage gate mechanism 19 may be of a fixed type.Furthermore, a leaf spring 98 is provided below the bottom plate 25, and the bottom plate 25 is in weak contact with the conveyor belt of the opposing banknote storage mechanism. Other than the above, since it is the same as the case of the 1,000 yen bill described above, further explanation will be omitted. In conclusion, the banknote temporary storage mechanism 80 mainly consisting of the ejected banknote storage mechanism 60 and the reject banknote storage case 81 will be explained based on the perspective view of FIG. 5. Note that FIG. 5 shows only the left half of the banknote temporary storage mechanism 80. A banknote conveyance path is formed by feed rollers 92, 94, conveyor belt 96, and the like. A thin fan-shaped switching member 76 and a guide member 77
and are attached to shaft 75 at one end of each. Moreover, the switching member 76 is connected to the shaft 75.
The guide member 77 is rotatably attached to the shaft 75 and at the same time is fitted through a weak torsion spring 78. Therefore, when the banknotes are not being conveyed, the tip of the guide member 77 is connected to the feed roller 92.
is pressed lightly against the shaft to which it is attached. Reference numeral 60 denotes a removed banknote storage mechanism, the detailed structure of which will be described later, and only the removed banknote storage case is shown here. Reference numeral 81 denotes a reject banknote storage case, whose detailed structure will be explained later. Since the configuration is as described above, its operation is as follows. The banknotes fed out from the banknote feeding mechanism 40 (FIG. 3) are fed between a conveyor belt 96 and a feed roller 94. If the delivered bill is in a normal state, the guide member 76 is in the position shown by the solid line in response to the command. Therefore, the banknote passes over the left side surface of the guide member 76 and enters the takeout banknote storage mechanism 6.
0 is placed in the storage case. At the same time, the storage case is rotated so as to open the outlet to the outside, as will be described in detail later. In this state, the customer can take out the paid bills. Of course, once the customer finishes taking out banknotes, the storage case will automatically return to its original position and the exit will be housed inside the device. A more detailed explanation of this area will be given later. On the other hand, when the banknote sent as described above is a rejikute banknote, the switching member 76 moves to the position indicated by the two-dot chain line by rotation of the shaft 75. Therefore, the banknotes are guided on the right side of the switching member 76, are held between the conveyor belt 96 and the right side of the guide member 77, and are fed into the reject banknote storage case 81 with a conveying force. Ru. Note that since the torsion spring 78 is weak, the force with which the guide member 77 pushes the banknote is also weak, and there is no fear that the banknote will be dented at the contact portion. Next, the already mentioned banknote storage gate mechanism 19,
The structure and operation of the banknote temporary storage mechanism 80, which includes the banknote storage mechanism 20, the banknote position regulation lever 26, the banknote feeding mechanism 40, the take-out banknote storage mechanism 60, the reject banknote storage case 81, etc., will be described in more detail and in detail. FIG. 6 is a side view of the banknote storage gate mechanism 19, and FIG. 7 is a front view thereof. First, in FIG. 6, a conveyor belt 5 stretched by belt pulleys 1 to 3 and an intermediate pulley 4 is moving in the direction of the arrow. When a banknote is introduced from the direction of arrow P, it passes between two guide plates 8 and 9 installed at a narrow interval, and passes between a belt pulley 1 and a pressing roller 6 opposed to it and pressed by a spring 7. Conveying force is given to . At this point, it is possible to switch between changing direction to the storage direction or continuing straight ahead. The direction change guide rail 11 performs this switching. The direction change guide rail 11 has fork-shaped ends at both ends as shown in the front view of FIG. One end of the belt pulley 1 can be switched between a position sandwiching the belt pulley 1 and a position facing the belt pulley 1 with a certain gap therebetween. This direction change guide rail 11 has a long hole 11a, and a fixed shaft 15 passes through this long hole 11a. Further, a pressing roller 12 is inserted into the other fork-shaped end of the direction change guide rail 11, and is connected to the same fork-shaped portion of the arm 13 via a pin 16. The arm 13 is fixed to a rotation shaft 14 at the other end. In other words, the direction change guide rail 11 and the arm 13
and constitute a link mechanism that is rotatably connected via a pin 16 and rotatably supported by a rotating shaft 14 and rotatably and movably supported by a fixed shaft 15. Conceivable. Therefore, its operation is as follows. 6th
In the figure, the arm 13 rotates as indicated by a double-headed arrow R, and the solid line indicates the banknote storage direction. A chain line of the arm 13 indicates its center position. At this time, the presser roller 12 is pressed against and comes into contact with the conveyor belt 5, and the direction change guide rail 11 is moved to a position indicated by diagonal lines (highlighted in the figure) due to the constraint relationship between its elongated hole 11a and the fixed shaft 15. Take. A path for banknotes is formed between the left side surface of the direction change guide rail 11 and the conveyor belt 5. Moreover, at this time, a strong conveying force is simultaneously applied to the banknote between the pressing roller 12 and the conveying belt. Furthermore, by positioning the press roller 12 as close to the banknote storage position as possible, it is possible to support the weak conveying force to the banknote storage position. Furthermore, even if the pressing roller 12 is brought close to the storage position as described above, it is completely separated from the conveyor belt 5 in the next step, so there is no possibility of jamming between the pressing roller 12 and the next banknote, which has been a problem in the past. Next, when the arm 13 is centered at the dashed-dotted line position to the right of the double-headed arrow R, the banknote is allowed to travel straight. At this time, at the same time as the press roller 12 is detached from the conveyor belt 5, the direction change guide rail 11 is at the position shown by the two-dot chain line, and the banknote passes along the right side thereof. Next, the bill storage mechanism 20 will be explained with reference to FIGS. 8 to 11. Figures 8 to 10
Each figure shows a front view, and FIG. 11 shows a side view. FIG. 8 shows the state before the banknotes are stored, and the newly conveyed banknotes 10 are lifted up between the conveyor belt 5 and the rotation guide plate 22 so that the edges on both sides are different from the middle part as shown in the figure. It has become a state of being.
Bills 10A are already stored and stacked on the bottom plate 25. 21 is a bearing plate that supports the belt pulley shaft. The rotation guide plate 22 can rotate approximately perpendicularly upward around a rotation axis 23 perpendicular to the plane of the paper. A supplementary explanation will be given with reference to FIG. 11, which is a side view of FIG. 8. Conveyor belt 5 is belt pulley 1
3 and the intermediate pulley 4 are driven in the direction of the arrow by a motor (not shown). Reference numeral 6 denotes a press roller facing the belt pulley 1; 11 a direction change guide rail belonging to the banknote storage gate mechanism 19 described above; and 12 a press roller for the conveyor belt 5 which interlocks with the direction change guide rail 11. Next, the operation of this banknote storage mechanism 20 will be described. First, a banknote is inserted from the P direction as shown by the broken line arrow in FIG. 11, and the direction change guide rail 11
The sheet advances along the guide surface of the sheet, receives driving force from the presser roller 12, and is conveyed toward the belt pulley 2. At the belt pulley 2, the edges on both sides in the direction perpendicular to the conveyance direction of the banknotes are guided along the rotation guide plate 22, and when viewed from the front, it looks as shown in Fig. 8. ing. Therefore,
Since the banknotes 10 are lightly pressed against the conveyor belt 5, the frictional force between the banknotes 10 and the conveyor belt 5 ensures reliable conveyance. In other words, the banknotes 10 are transported by friction with the banknotes 10A already stored and by the driving force. Then, position the position adjustment lever 2 at the position where it should be stored.
6 and the banknote 10 stops. Note that the tip of the banknote 10 is connected to the position regulating lever 26.
It is necessary that the rear end portion be away from the presser roller 12 when it is in contact with the presser roller 12. This is because the conveyance force by the presser roller 12 is strong.
This is because if the movement is forcibly stopped by the position regulating lever 26, the banknote 10 will be deformed and jammed. The pressing roller 12 is desirably installed so that when the rear end of the banknote 10 is detached therefrom, the leading end is close to the position regulating lever 26. Now, in the next step, based on the storage order, the 9th
As shown in the figure, the rotation guide plate 22 rotates substantially perpendicularly upward in the direction of the arrow. As a result, both side edges of the banknote 10 come off the rotation guide plate 22 and are completely stacked on top of the banknote 10A already stored. In the next step, as shown in FIG. 10, the rotation guide plate 22 is returned to its original position. This completes the conveyance and storage of banknotes 10.
In this state, the next bill arrives. Note that the bottom plate 25 is in contact with the conveyor belt 5 with a weak contact pressure, or is in a state where there is no contact pressure. This is because the banknote 10 has contact pressure with the conveyor belt 5 due to the rotation guide plate 22, and is therefore given a conveying force. To add more,
On the stacked storage of banknotes 10, stored banknotes 10A
It is sufficient that the surface of the conveyor belt 5 is close to the conveyor belt 5. Next, the bottom plate elevating mechanism 30 for storing and dispensing banknotes.
The configuration will be explained with reference to FIG. 3a. Reference numeral 25 indicates the bottom plate of the bill storage chamber, 31 indicates columns attached to both sides of the bottom plate 1, 32 indicates four pincushion-shaped guide rollers that support the columns 2 so that they can move up and down, and 33 indicates each column 2. 34 is a mutually interlocked pinion that meshes with this rack 33, and 37 is a motor capable of forward and reverse rotation that rotates this pinion 34 via gears 36A and 36B. The above is the main part of the bottom plate elevating mechanism 30. Above this, the banknote conveying belt 5 is connected to the belt pulleys 1 to 3.
3. Driven by intermediate pulley 4. Next, the operation of this bottom plate elevating mechanism 30 will be described. The banknotes 10 to be stored are stored on the bottom plate 25 by the banknote storage mechanism 20. At this time, the bottom plate 25 is driven by the motor 37 as follows. In response to the storage command signal, the motor 37 rotates in the forward direction for a preset time and then stops.
It is controlled to reverse for another very short set time and then stop again. Therefore, first, the bottom 2
5 is a banknote 10A that has been moved upward and has already been stored.
The surface of the motor 37 comes into contact with the conveyor belt 5, and the rotation of the motor 37 is prevented by the load or contact pressure.
In this case, the rotating shaft of the motor 37 itself may be blocked by the load, or the rotating shaft may slip when the torque exceeds a certain level, and the contact pressure may be limited. Then, at the set time, the motor 37 stops. Next, the motor 37 rotates in reverse for another extremely short set time and then stops again, so that the bottom plate 25 is slightly lowered and the surface of the banknote 10A is slightly separated from the surface of the conveyor belt 5. However, if there are many banknotes 10A, the two may remain in contact due to gaps between the banknotes.
However, the contact pressure would be very weak. Therefore, in the above-mentioned state, there is no problem in conveying banknotes due to the banknote conveyance force of the conveyor belt 5 as described above. Next, in the case of dispensing, the same operation as in the previous stage in the case of storage described above is performed. In other words, the motor 37 is rotated in the normal direction for a set time by the dispensing command signal, and then stopped. At this time, the surface of the banknotes 10A stacked and stored on the bottom plate 25 is in a state of strong contact pressure with the conveyor belt 5. Therefore, the bill dispensing roller 42 reliably contacts the surface of the bill 10A, and the dispensing operation is also reliably performed. Although a detailed explanation of the control of the motor 37 will be omitted, it is easily performed by a sequence control circuit. Next, the bill position regulating lever 26 and the bill feeding mechanism 40 will be explained with reference to FIG. 12. FIG. 12 shows its side view. First, the configuration of this mechanism will be explained. 1st
In FIG. 2, the banknotes 10 are stored in a stacked manner on the bottom plate 25 of the storage chamber. And 26
27 is a rotating shaft that rotatably supports the position regulating lever 26; 28 is a spring; 48 is a push shaft fixed to a holding frame 49 of a bill feeding roller unit to be described later; 42 is a bill This roller is used to feed out rubber, and has an uneven rubber part on a part of its circumference. Reference numerals 43 and 44 are a well-known set of rollers for preventing multiple bills from passing through. The upper roller 43 for preventing the passage of multiple sheets has three thin disks arranged with a certain gap in the axial direction. Similarly, in the lower one 44, two disks having a smaller diameter than the above-mentioned disks are arranged between the above-mentioned disks. The outer peripheries of both disks are placed in contact with each other with a slight distance between them. This interval is adjustable, and how to choose this interval is a matter of know-how. Also, usually the larger disk is made of a metal material, and the smaller disk is made of a softer material at least on its outer periphery. The upper multiple-sheet passage prevention roller 43 is attached to the drive shaft 41, and is connected in the same direction as the banknote feeding roller 42 so as to equalize the linear velocity at the outer periphery. Further, the lower multiple-sheet passage prevention roller 44 has a built-in one-way clutch so that it cannot rotate in the dispensing direction but can rotate in the opposite direction. A frame 49 that mainly holds the feeding roller 42 and the multiple bill passage prevention roller 43 constitutes a bill feeding roller unit. The drive shaft 41 rotates only clockwise in the figure. The holding frame 49 of the banknote feeding roller unit is connected to the drive shaft 4.
It is rotatably supported coaxially with 1. Furthermore, the holding frame 49 is connected to a rotating portion of the electromagnetic actuator 46. Furthermore, a spring 47 is attached to the holding frame 49 to apply a force to rotate it counterclockwise, and a stopper 47A is provided in response to this force. It should be noted that FIG. 3a is a perspective view of the arrangement of each of the above members, so that the relative positions thereof can be understood. That is, there are three banknote feeding rollers 42 and two sets of multiple banknote passage prevention rollers 43 and 44, which are arranged alternately with the rollers 42 in the axial direction. Next, for the sake of convenience, the operation of this mechanism will be explained separately for the case of storing banknotes and the case of dispensing banknotes. First, in the case of banknote storage, the solid line in FIG. 12 corresponds to the case. In other words, the stored banknotes 10
The outer peripheral surface of the bill feeding roller 42 is separated from the surface of A. At the same time, the banknote position regulation lever 26 is also located at the position indicated by a solid line and a partially broken line, and a regulation surface 26a at the tip thereof blocks the front surface (left side in the figure) of the banknote 10A. Next, when a bill payout command is issued, the movable part of the electromagnetic actuator 46 operates upward based on the command signal, and the holding frame 49 is rotated clockwise about the drive shaft 41. At the same time,
A push shaft 48 fixed to the holding frame 49 pushes the upper edge of the banknote position regulating lever 26, and the lever 26
rotates clockwise and moves to the position indicated by the two-dot chain line in the figure. At the same time, the outer peripheral surface of the bill feeding roller 42 comes into contact with the surface of the bill 10. In the above state, the bill feeding roller 42 is moved to the drive shaft 4.
1, the banknotes are rotated in this clockwise direction together with the multiple banknote passage prevention roller 43, and the stored banknotes are sequentially fed out one by one. Then, a plurality of the fed bills pass through prevention rollers 43, 4.
The set of 4 ensures that each sheet passes through one by one. In other words, even if two banknotes try to pass through the gap between the multiple-sheet passage prevention rollers 43 and 44, the lower banknote will separate from the upper banknote due to the large friction with the rubber surface of the roller 44. It will stay in that spot. Banknotes that have passed through these
The paper is sent out through the space between the sending roller 51 shown in FIG. 12 and a pressing roller (not shown) installed opposite thereto. Naturally, the drive shaft 4
The electromagnetic actuator 4 is instructed to rotate according to the number of coins to be paid out, and the electromagnetic actuator 4 is operated only during the period of payout.
6 performs a suction operation. When the command for dispensing is completed, the operation of the electromagnetic actuator 46 is canceled and the bill dispensing roller unit also returns to the position indicated by the solid line. The push shaft 48 then moves to the shaded position. Simultaneously with the roller movement, the bill position regulating lever 26 is rotated counterclockwise by the spring 28 to a position where it hits the push shaft 48 and returns to its original position (the position shown by diagonal lines).
If there is a banknote stuck at the multiple-sheet passage prevention rollers 43 and 44, the banknote position regulating lever 26 is operated to return the banknote to push it back to the normal storage position. In this way, it becomes possible to store banknotes. Next, the banknote temporary storage mechanism 80 will be explained in detail based on the side view of FIG. 13 and the back view of FIG. 14. In FIG. 13, 91 to 94 are bill feeding rollers, 95 is a guide plate, and 96 is a conveyor belt. Each of the above members rotates or moves in the direction of the arrow to form a banknote conveyance road surface. A shaft 75 passes through one end of a thin fan-shaped switching member 76, and both are fixed. Further, a guide member 77 is rotatably fitted into the shaft 75. The shaft 7 between the switching member 76 and the guide member 77
As shown in the rear view of FIG. 14, the positional relationship in the five directions is such that an appropriate number of bill feeding rollers 92 and conveying belts 96 are placed between them. Further, a weak torsion spring 78 is provided between the shaft 75 and the guide member 77, and lightly presses the guide member 77 against the shaft of the bill feeding roller 92. Reference numeral 61 designates a take-out banknote storage case, 62 a rotation shaft of the take-out banknote storage case, 81 a reject banknote storage case, and 82 a leaf spring. Next, the operation of this banknote temporary storage mechanism 80 will be described. The banknote 10 passes between the surface of the conveyor belt 96 that is in contact with the feed roller 91 and the guide plate 95,
It moves between the feed roller 94 and the conveyor belt 96.
If the banknote 10 is sent out in a normal state, the shaft 75 is rotated by the command and the switching member 76 is moved to the position shown by the two-dot chain line. Therefore, the banknotes 10 pass over the left side surface of the switching member 76 and are thrown into the takeout banknote storage case 61. After the insertion of banknotes is completed, the takeout banknote storage case 61 rotates around the shaft 62 to open the takeout port to the outside of the device. It closes automatically after the customer takes out the banknotes. The operation of opening and closing the removed banknote storage case 61 will be explained in more detail later. If the bill is sent out in an irregular state, the shaft 75 rotates based on the command and the switching member 76
moves to the position shown by the solid line. Therefore, the banknote 10 passes through the right side of this switching member 76,
The right side of the guide member 77, which had been in the position shown by the two-dot chain line, is pushed between the feed roller 92 and the surface of the conveyor belt 96 that is in contact with the conveyor belt 96, and the guide member 77 is moved along the line against the torsion spring 78. press into position,
A conveyance force is obtained by being sandwiched between the guide member 77 and the conveyor belt 96 that contacts the feed roller 92, and the bill is thrown into the reject banknote storage case 81. After the banknotes 10 are inserted into the reject banknote storage case 81, the guide member 77 returns to the position indicated by the two-dot chain line, and its tip functions to push the upper end of the banknote 10 to make it stand up. This action, together with the leaf spring 82, has the effect of preventing the banknotes 10 from falling within the storage case and facilitating the insertion of the next banknote. Note that since the torsion spring 78 is weak, there is no risk that the banknote 10 will be pushed and deformed by this force. Note that there are no more than 10 banknotes in the removed banknote storage case 61.
It is sufficient to accommodate up to 10 bills, whereas the reject bill storage case 81 normally needs to accommodate several 10 bills. Therefore, there is a difference in the bill storage space between the two. In conclusion, details of the ejected banknote storage mechanism 60 will be explained with reference to FIGS. 15 to 18. FIG. 15 shows a rear view of this embodiment, and FIG. 16 shows a side view. Reference numeral 61 denotes an ejected banknote storage case, 62 a shaft serving as a rotation center for opening and closing this case, 63 a side plate of this mechanism, 64 attached to the shaft 62 with a torsion spring, and both ends thereof are connected to the side plate 63.
and the removed banknote storage case 61, and applies force in the direction of closing this storage case 61. Further, a blocking portion 70 is provided corresponding to a portion of the ejected banknote storage case 61, for example, the receiving metal fitting 61a through which the shaft 62 passes, and
1 is closed, the receiving metal fitting 61a is connected to the blocking portion 70.
You will come across. An angle 6 is provided on the bottom surface of the ejected banknote storage case 61.
5 is attached, and a latching pin 66 is provided for this. On the other hand, a drive pin 69 is provided on a disc 68 directly connected to the shaft of the motor 67. Drive pin 69 attached to disk 68
is a locking pin 66 provided on the angle 65.
are opposed to each other with their respective end surfaces almost in contact with each other, and are also placed at a slight distance (h as described later) from the contact portion 65a of the angle 65. FIG. 17 is a plan view showing related parts such as the drive pin, in which the disk 68 rotates in the direction of the arrow, that is, counterclockwise, and at the origin of operation, the outer surface of the drive pin 69 and the contact portion 65a of the angle 65. There is a distance h from the surface of Next, FIG. 18 is a plan view and a side view showing a detector for detecting the rotational position of the disk 68 and, by extension, the fully open position of the banknote storage case 61. In FIG. 18a, 71A and 71B are disks 6
8, light shielding pieces arranged at 180 degrees from each other, 7
Reference numeral 2 designates one photoelectric switch placed at a position corresponding to the light shielding pieces 71A and 71B. The photoelectric switch 72 has a built-in light projecting section and a light receiving section, and receives or blocks light depending on the position of the light blocking pieces 71A and 7AB. Next, the operation of this embodiment of the bill ejection port opening/closing mechanism will be explained. When the storage of a predetermined banknote into the banknote storage case is detected in the direction of the arrow in FIG. 16, the motor 67
is activated in the direction of arrow R in FIG. At this time, because of the gap h between the outer surface of the drive pin 69 and the surface of the contact portion 65a of the angle 65, the rotation of the drive pin 69 does not immediately push the contact portion 65a. They only come into contact after turning a certain angle. As the drive pin 69 rotates, the contact portion 65
When a is pushed downward in FIG. 17, the banknote storage case 61 rotates in the direction of the arrow from the position shown by the solid line in FIG. 16, and when the drive pin 69 rotates half a rotation, it tilts to the position shown by the two-dot chain line. In other words, the outlet of the storage case 61 is opened. At the same time, the light shielding piece 71B fixed to the disk 68 to which the drive pin 69 is attached operates the photoelectric switch 72 (FIG. 18). Note that before the drive pin 69 is activated, the light shielding piece 71A is in a position where the photoelectric switch 72 is operated. Therefore, when the disk 68 rotates half a rotation, the photoelectric switch 72
The motor 67 is stopped by the operation. In this state, the banknote storage case 61 is opened, and the customer can take out the paid banknotes. Now, when all the banknotes are taken out from the storage case 61, this is detected by a detector (not shown), and the motor 67 and hence the drive pin 69 are restarted. The next half rotation of the drive pin 69 returns the banknote storage case 61 to its original position. At the same time, the light shielding piece 71A operates the photoelectric switch 72,
This causes the motor 67 to stop. Note that in FIG. 16, when the banknote storage case 60 is closed, even if you try to forcefully open it by hand in the direction of the arrow, the latch pin 66 and the drive pin 6
Since the end faces of 9 and 9 are close to each other and face each other,
The removed banknote storage case 61 cannot be opened because it is mechanically blocked. Also, when the banknote storage case 61 is in an open state, the stored banknotes are taken out, but for some reason, even though the banknotes are taken out, the hand is still inside, and the case 61 is closed as described above. Assume that a hand is about to be caught between the banknote storage case 61 and the outer wall. At this time, the drive pin 69 continues to rotate, but the force that causes the banknote storage case 61 to close is not due to the rotational force of the motor 67, but is due to the force of the torsion spring 64, which may cause damage to the hand. There's no fear.

【Effect of the invention】

Due to the configuration and operation described above, the present invention has the following excellent effects. (1) Bills of multiple denominations can be stacked and stored, and one specific denomination of them, for example, 1,000 yen bills, can be dispensed, so it is possible to pay for high-value items with 10,000 yen or 5,000 yen bills. It can be incorporated into automatic ticket vending machines that issue high-priced tickets, or it can be incorporated into simple automatic exchange machines that only exchange 10,000 yen and 5,000 yen bills for 1,000 yen bills. Therefore, it is possible to respond to respective market needs that have been increasing recently. (2) Moreover, since the 1,000 yen bill can be recycled, in other words, the banknotes for dispensing can be reused from the ones inserted and stored, which saves the installation user's operational effort. In other words, the amount of replenishment is reduced, and the interval between replenishment times becomes longer. (3) Since the storage areas for a plurality of banknotes are stacked in three tiers, and the top tier is used for dispensing, the structure of the bill dispensing mechanism can be made particularly easy and compact.
This directly leads to increased reliability, lower cost, and smaller size of this device. (4) Since a reject banknote accommodating section is provided to accommodate banknotes sent out in an irregular state, the banknotes sent out from the banknote dispensing mechanism deviate from the normal state, for example, if two sheets are stacked on top of each other, or if there is a predetermined gap between the banknotes. It is possible to suppress the occurrence of erroneous accounting and banknote jams that occur when there are no intervals between the lines and the lines are almost continuous.
