  2. Description of the Related Art In recent years, automatic teller machines (hereinafter referred to as ATMs) have been placed not only in bank stores but also in retail stores such as supermarkets and convenience stores, and the forms of maintenance are becoming diverse.

  In the ATM, a plurality of storages are provided in order to store banknotes separately for each denomination. In the maintenance scene, in order to take in and out banknotes in the ATM, one dedicated loading / recovery box is provided, and the banknotes are taken in and out while checking the denomination and number of banknotes. However, with changes in the installation environment as described above, there are cases where banknotes are taken in and out away from ATMs, and there is a demand for direct withdrawal from the storage.

  On the other hand, in order to maintain the weight of the stored banknote, the current storage supports the push plate on which the banknote is placed at both ends. For this reason, at least one set of push plate drive belts and their support mechanisms obstruct access. Therefore, we want to eliminate the driving belt and support mechanism on the operator side. However, in this case, there is a problem that the drive belt and the support mechanism that are only on one side cannot withstand the weight of the bill.

  Further, the object is that the linear motion mechanism is provided on the side opposite to the storage space of the side plate, and is composed of a linear guide, a holder, and a drive belt, and when the push plate is driven toward the pickup roller. When the drive belt urges the holder between the side plate and the linear guide and drives the push plate away from the pickup roller, the drive belt is on the side opposite to the side plate of the linear guide. This is achieved by providing the drive belt to urge the holder.

  Further, the object is that the linear motion mechanism is provided on a side opposite to the storage space of the side plate facing the storage door, and includes a linear guide, a holder, and a drive belt, and the push plate is attached to the pickup roller. The drive belt urges the holder between the side plate and the linear guide, and the drive belt is driven by the linear guide when the push plate is driven away from the pickup roller. The drive belt is provided so as to urge the holder on the side opposite to the side plate, and the push plate is placed on the side opposite to the storage space of the side plate perpendicular to the storage door and adjacent to the second guide means. This is achieved by providing an elastic body that urges toward the pickup roller.

  The object can be moved in the thickness direction of the paper sheet on the opposite side of the storage space of the side plate perpendicular to the storage door and adjacent to the second guiding means, and the push plate is moved to the pickup roller. A second linear motion mechanism that abuts against the pickup roller, and the second linear motion mechanism is urged toward the pickup roller by the elastic body.

  The above object is achieved by the elastic body being bent and arranged by a pulley having the same rotation center as that of the gate roller.

  The above-mentioned object is achieved by urging the elastic body from a position away from the pickup roller by a predetermined distance.

  Further, the object is to provide a linear motion mechanism comprising a linear guide, a holder, and a drive belt, the linear motion mechanism being provided on the opposite side of the storage space of the side plate facing the storage door, wherein the drive belt is On the pickup roller side of the holder, the holder is fixed between the side plate and the linear guide, and on the opposite side of the holder to the pickup roller, the holder is on the opposite side of the linear guide to the side plate. This is achieved by being a drive belt provided to be fixed to the belt.

  Further, the object is to provide a linear motion mechanism comprising a linear guide, a holder, and a drive belt, the linear motion mechanism being provided on the opposite side of the storage space of the side plate facing the storage door, Two drive belts having a one-way clutch in between and transmitting force in mutually different rotational directions. When transmitting force toward the pickup roller to the holder, the side plate and the linear guide The drive belt fixed to the holder on the opposite side of the side plate of the linear guide when the drive belt fixed to the holder acts between them and transmits force to the holder on the opposite side of the pickup roller. This is achieved by the fact that the belt is a drive belt configured to act.

  According to the present invention, since the storage door for taking in and out the banknote and the drive mechanism for the push plate can be arranged at positions separated from each other, there is no obstacle even if the banknote is taken in and out directly from the storage door. Even when the support mechanism is arranged only on one side, it is possible to provide a paper sheet storage device that can reduce the load on the support mechanism of the push plate.

First, a general ATM banknote handling apparatus will be described with reference to a schematic configuration diagram shown in FIG.
In FIG. 1, in order to show the function of the banknote storage apparatus 8 which is the object of the present invention, the operation of the banknote handling apparatus 1 will be briefly described.
The deposit / withdrawal port mechanism 2 divides banknotes thrown into a bundle one by one and deposits them into the banknote handling apparatus 1 and withdraws the banknotes dispensed from the banknote handling apparatus 1 into a bundle. I do. The shutter 3 is adjacent to the deposit / withdrawal slot mechanism 2 and opens the deposit / withdrawal slot mechanism 2 when the operator puts in / outs banknotes.

  The conveyance path 4 and the switch 5 convey a banknote to a predetermined destination. At the time of depositing operation, the bill sent out from the deposit / withdrawal port mechanism 2 is judged by the discrimination unit 6 for authenticity, denomination, etc., and normal bills are accumulated in the temporary stacking unit 7. After the denomination and the number of sheets are confirmed by the operator, they are transported from the temporary stacking unit 7 to the storage 8. In many cases, a plurality of storage boxes 8 are provided, and they are collected separately according to denominations. Banknotes that are not used for payout are accumulated in the reject box 9.

At the time of the withdrawal operation, a predetermined number of sheets are sent out from the storage box 8, and after checking for abnormalities such as repeated feeding by the discrimination unit 6, normal banknotes are accumulated in the deposit / withdrawal port mechanism 2.
Thus, the storage 8 stores the banknotes received or used for withdrawal. Since a large amount of banknotes is traded in ATM, the storage 8 has a capacity of several thousand sheets. For example, when about 2000 to 3000 sheets are stored, since one banknote is about 1 g, the storage 8 stores 2-3 kg of banknotes.

2 to 4 show the detailed configuration of the storage 8 of the present invention.
FIG. 2 is a side view of the storage box 8, and the storage box 8 that stores thousands of sheets is long in the thickness direction of the banknotes, and is not shown in the drawing.
3 and 4 are top views of the storage case 8. FIG.
In FIG. 2, the storage box 8 stacks banknotes in the space A in the thickness direction and stores them in a bundle, and takes out and puts banknotes one by one as indicated by arrows b.
The element which comprises the storage 8 and its operation | movement are demonstrated.
The switcher 10 is a banknote entrance / exit of each storage 8 and switches the banknote transport direction by changing the position by an actuator M3 (shown in FIG. 3) such as a solenoid. The pickup roller 11 is a cylindrical roller having a high friction portion such as rubber on a part of its outer peripheral surface. The feed roller 12 has a shape in which a large-diameter cylinder and a small-diameter cylinder are alternately overlapped, and a high-friction portion such as rubber is provided on the outer peripheral surface of the large-diameter portion. One end of the bracket 13 is attached to the rotation shaft of the feed roller 12 and swings around the same rotation center. A rotating shaft of a pickup roller 11 is attached to the other end of the bracket 13, and the pickup roller 11 is pressed against a bundle of bills by being urged by a pickup spring 14.

  The gate roller 15 has a shape in which a large-diameter cylinder and a small-diameter cylinder are alternately overlapped, and a high-friction portion such as rubber is provided on the outer peripheral surface of the large-diameter portion. The gate roller 15 faces the feed roller 12 so that the large diameter portion corresponds to the small diameter portion. The large diameter portions of each other are arranged so as to slightly overlap in the diametrical direction. Further, the rotation direction of the gate roller 15 is rotated only in the direction in which the banknote is taken into the storage 8 by a one-way clutch or the like. This prevents the banknotes from being stacked and sent out.

  The pinch roller 16 is a rotating body such as a bearing, and applies a conveying force to the bill by rotating in contact with the large diameter portion of the feed roller 12. The drive motor M1 (shown in FIG. 3) is a rotary actuator such as a step motor, and directly drives the feed roller 12 to rotate, and synchronously drives the pickup roller 11 via a gear (not shown). The pinch roller 16 abuts on the feed roller 12 or rotates following the banknote. The gate roller 15 is rotated following the banknote only in the direction of taking the banknote into the storage 8.

  The feed guide 17 is provided such that a part of the pickup roller 11 and the feed roller 12 protrudes toward the bill side. Further, the gate guide 18 is provided so that a part of the gate roller 15 and the pinch roller 16 protrudes toward the bill side. Further, the feeding guide 17 and the gate guide 18 constitute a bill conveyance path so as to connect the space A and the arrow B.

  The side plate 19 is a plate provided so as to surround the stored banknote and to be adjacent to the three sides of the banknote. The push plate 20 is a plate on which stored banknotes are placed, and is provided at a position facing the pickup roller 11. The pressing plate 20 is attached to a linear motion mechanism that moves linearly in the thickness direction of the banknote through a slit 21 provided on the side plate 19 on one side.

  As an example of the configuration of the linear motion mechanism, the holder 22 is provided so as to be in contact with a cylindrical support shaft 23, and has a low friction body such as a bearing between the holder 22 and the holder 22 in the axial direction of the support shaft 23. It can be moved. Here, with respect to the rotation direction, the movable range is limited by the contact between the slit 21 and the holder 22 or the contact between the side plate 19 and the pressing plate 20.

M2 (shown in FIGS. 3 and 4) is a push plate drive motor, which operates the drive belt 25 by rotating the pulley 24. The drive belt 25 is fixed to the holder 22.
On the other hand, a push plate spring 26 is attached to a side below the feed roller 12 or the gate roller 15 at a side perpendicular to one side attached to the holder 22 of the push plate 20 to urge the push plate 20 upward. . In order to increase the operating range of the pressing plate 20, the pressing plate spring 26 should have a long free length, and is structured to be diffracted by the spring pulley 27.

  Surrounding these elements, a storage case 30 and a storage door 31 (shown in FIG. 3) are provided. One end of the aforementioned push plate spring 26 is fixed to the storage case 30. The storage door 31 can be opened and closed with the hinge 31h as an axis, and banknotes stored in the space A can be directly taken in and out. Here, since the mechanism for supporting the push plate 20, for example, the support shaft 23, the drive belt 25, the push plate spring 26, and the like is disposed on a side different from the storage door 31 of the stored banknotes, There is no obstacle.

With the above configuration, when a bill is sent out from the storage case 8, the push plate 20 is moved to bring the bundled bill placed thereon closer to the pickup roller 11. Next, a conveying force is intermittently applied to the banknote by a high friction portion provided in a part of the pickup roller 11. The banknotes are separated one by one by the feed roller 12 and the gate roller 15 and are sent out by the pinch roller 16.

  Here, due to changes in the ATM installation environment, there is a demand to directly put in and out banknotes for each storage 8. Further, downsizing of the device is a constantly required issue. Therefore, as described above, the linear motion mechanism that supports the push plate 20 is provided only on one side of the stored banknote and is disposed on the opposite side of the storage door 31. The storage door 31 can be opened and closed, and banknotes stored in the space A can be directly taken in and out. Furthermore, since the mechanism for supporting the push plate 20, for example, the support shaft 23, the drive belt 25, the push plate spring 26, and the like is arranged on a side different from the storage door 31 of the stored banknotes, it may become an obstacle at the time of taking in and out. Absent. In addition, the storage door 31 side of the side plate 19 is bent as shown by the side plate 19a, and the storage width in the banknote short side direction is widened compared to the opposite side, so that handling in and out can be improved.

  Further, if the length of the linear motion mechanism protruding from the side plate 19 is the same, the installation area occupied by the linear motion mechanism can be reduced by arranging it on the short side of the banknote as compared with the case of arranging on the long side. The device can be downsized.

  Here, as described above, 2 to 3 kg of banknotes are stored in the storage 8. Therefore, a great load is applied to the holder 22 that supports the push plate 20 and the drive motor M2 that drives the holder 22. This is shown in FIG. In addition, the diagonal line inside the holder 22 shows the bearing 22b.

FIG. 5 is a schematic diagram showing the force acting on the pressing plate.
In FIG. 5, G indicates the origin and is determined at the lower end of the holder 22. W is the weight of the bill P or the pressing plate 20 and works at a distance Lw from the origin G. T is a force given by the tension of the drive belt 25, and works on the origin G. K (dx) is a force from the push plate spring 26 and works at the position of the distance Lk. Dx is the extension length of the push plate spring 26, and K (dx) increases as dx increases. Nu and Nd are drags acting between the holder 22 and the support shaft 23, Nu is acting at the upper end of the holder 22, Nd is acting at the lower end of the holder 22, and the distance is Lh apart. When the friction coefficient between the bearing 22b and the support shaft 23 is μ, a frictional force of μ × Nu at the upper end and μ × Nd at the lower end is generated in the direction opposite to the moving direction of the holder 22.

  In such a system, when there is no push plate spring 26, the following equation is established.

これらの式より、ベアリング２２ｂに働く力Ｎｕを求めると、

From these equations, when the force Nu acting on the bearing 22b is obtained,

となる。

It becomes.

  In these equations, the weight W is determined from the number of specifications, and the distance Lw is determined from the size of the bill. Further, since it is better to reduce the tension T and reduce the load of the push plate drive motor M2, it is preferable that the friction coefficient μ is also small. On the other hand, the resistance Nu and the tension T become smaller when Lh is larger, but with the support shaft 23 having the same length, the movable range of the holder 22 becomes narrower as Lh becomes larger, so the capacity of bills that can be stored decreases. Therefore, there are implementation restrictions.

Here, for example, if the weight W is 3 kg, the starting acceleration of the pressing plate 20 is 30 m / s ² , Lw is 0.1 m, and Lh is 0.03 m, the drag Nu reaches about 40 kgf from Equation 4. Further, when the friction coefficient μ is 0.1, the tension T is about 20 kgf according to Equation 5. When such an excessive load is generated, in the parts generally used in the bill handling apparatus, the bearing 22b, the drive belt 25, and the push plate drive motor M2 exceed allowable values, and there is a risk of damage or shortening of the life. . On the other hand, if parts that satisfy the load are used, an increase in size and a significant increase in cost cannot be avoided.

  Therefore, in the apparatus of the present invention, the push plate spring 26 is provided so that the push plate 20 is pulled upward. Therefore, Equation 2 is

となり、張力Ｔを低減できる。ここで、押板バネ２６は側板１９の３面のうち、ゲートローラ１５に近接した面に配置した。それにより式４は、

Thus, the tension T can be reduced. Here, the push plate spring 26 is arranged on a surface close to the gate roller 15 among the three surfaces of the side plate 19. Thus, Equation 4 becomes

となり、押板バネ２６の力Ｋ（ｄｘ）の符号が常にマイナスとなる。したがって、抗力ＮｕやＮｄを小さくするので、張力Ｔを直接的に小さくするだけではなく、抗力ＮｕとＮｄにより生じる摩擦力を低減して、さらに間接的に張力Ｔを小さくすることができる。

Thus, the sign of the force K (dx) of the push plate spring 26 is always negative. Therefore, since the drag Nu and Nd are reduced, not only the tension T can be reduced directly, but also the frictional force generated by the drag Nu and Nd can be reduced and the tension T can be further reduced indirectly.

  Here, since the spring pulley 27 is provided below the gate roller 15, in the section s shown in FIG. 2, a force pulling upward cannot be generated. However, the tension T and the drag force Nu increase when a large amount of banknotes are stored. Therefore, the push plate 20 is located below, and the extension length dx of the push plate spring 26 is increased, and a tensile force can be effectively applied.

  Depending on the configuration of the gate roller 15 and the gate guide 18, the spring pulley 27 has to be installed further downward, and the section s becomes larger. As shown in FIG. 2, when the push plate 20 and the push plate spring 26 are directly connected, the push plate spring 26 pulls the push plate 20 downward, which has an adverse effect. Further, spatial interference between the push plate spring 26 and the gate roller 15 or the gate guide 18 may occur.

  Therefore, as shown in FIG. 6, there is a configuration in which the push plate spring 26 is connected to the slide plate 31, and the slide plate 31 applies an upward force to the push plate 20.

FIG. 6 is a side view of a banknote storage device provided with another embodiment.
In FIG. 6, the slide plate 31 moves along the slide shaft 32 in the thickness direction of the stored banknotes, but the movable range is limited by the stop plate 33 provided below the gate roller 15 and the gate guide 18. When the push plate 20 is above the stop plate 33, that is, enters the section s, the push plate 20 and the slide plate 31 are not in contact with each other. However, in the section s, since the number of stored banknotes is small, the drag Nu and the tension T are small, and there is no problem.

FIG. 7 is a side view of a banknote storage device provided with another embodiment.
In FIG. 7, there is a configuration in which the spring pulley 27 is provided coaxially with the gate roller 15. In this case, there is a limitation in mounting such that the diameter of the spring pulley 27 needs to be smaller than that of the gate roller 15. However, the section s where the push plate spring 26 does not work can be reduced.

  Moreover, as shown in FIG.3 and FIG.5, the drive belt 25 and the support shaft 23 were arrange | positioned at the same distance from the accommodation banknote. Here, by changing the direction of the driving belt 25 as shown in FIGS. 8 and 9 and changing the position where the driving belt 25 pulls the holder 22 between upward and downward, the moment force can be further reduced.

FIG. 8 is a top view of a banknote storage device provided with another embodiment.
FIG. 9 is a schematic diagram of the push plate and the pointing mechanism.
8 and 9, when the holder 22 is pulled upward, the drive belt 25 applies a force between the support shaft 23 and the stored bill. Further, when the holder 22 is pulled downward, the drive belt 25 applies a force on the opposite side of the support shaft 23 from the stored banknote.

  For this purpose, the direction of the pulley 24 is changed to a right angle by the bevel gear 34. Further, the drive belt 25 is made parallel to the support shaft 23 by the backup roller 35.

  With this configuration, the force acting on the pressing plate 20 and the holder 22 is as shown in FIG.

FIG. 10 is a schematic diagram showing the force acting on the pressing plate.
In FIG. 10, an upward tension Tu and a downward tension Td are applied at positions separated from the support shaft 23 by a distance Lt. Thereby, when the push plate 20 moves upward, Equation 7 becomes

下方へ移動するときは、

When moving down,

となる。式８と式９において、張力ＴｕとＴｄの符号は常にマイナスであり、紙幣等によって生じるモーメントを低減する方向に働く。したがって、さらにモーメント力を小さくし、抗力Ｎｕと張力Ｔを小さくすることができる。

It becomes. In Expressions 8 and 9, the signs of the tensions Tu and Td are always negative, and work in the direction of reducing the moment generated by bills and the like. Therefore, the moment force can be further reduced, and the drag force Nu and the tension T can be reduced.

Similar effects can also be obtained with the configuration of FIG.
FIG. 11 is a schematic diagram of the push plate and the support mechanism.
In FIG. 11, instead of changing the direction of the drive belt 25 to a right angle, the drive belt 25 a is provided between the support shaft 23 and the stored banknote and the drive belt 25 b is provided on the opposite side of the support shaft 23 from the stored banknote. And it connects to the push plate drive motor M2 via the one-way clutches 36a and 36b, respectively. The one-way clutch 36a does not rotate when the holder 22 moves upward, and rotates freely when it moves downward. On the other hand, the one-way clutch 36b rotates freely when the holder 22 is moved upward, and does not rotate when the holder 22 is moved downward.

  With such a configuration, when the holder 22 is moved upward, the drive belt 25 a applies a force and pulls between the stored banknote and the support shaft 23. On the other hand, when the holder 22 is moved downward, the drive belt 25b pulls the holder 22 on the opposite side of the support shaft 23 from the stored banknote. Thereby, the same force relationship as FIG. 10 can be obtained.

  As described above, the bearing 22b is provided by providing the pressing plate spring 26 that biases the pressing plate 20 toward the storing bill in the side of the storing bill and in the thickness direction of the storing bill of the gate roller 15 and the gate guide 18. In addition, it is possible to reduce the load acting on the drive belt 25, and it is possible to configure the banknote storage device 8 that is low in cost and small in size and satisfies the life.
