Abstract

PROBLEM TO BE SOLVED: To provide a bill letting out machine capable of letting out bills stably by a low cost system. SOLUTION: When a cash cassette is set to the bill letting out machine, the shutter metal fitting attached to a shutter hooks the metal fitting 22 of a mechanism. The metal fitting of the mechanism is interlocked with the lifting of the shutter to be made to move up together with the shutter. This movement turns a timing belt 30, and the rollers 29a and 29b in the belt 30 are rotated. The gear pulley 26 fixed to the shaft 32 attached to the roller 29a is rotated together with the shaft 32, and the gear 25 which is contacted with the gear pulley 26 is also rotated. Together with the gear 25, a shaft 24 to which the gear 25 is attached is also rotate. Rollers 27a to 27d which turn a rubber belt 28 are attached to the shaft 24 at both ends and are turned together with the rotation of the shaft 24. The turning of the shaft 24 rotates the rubber belt 28 faced upward to hold a part of stacked bills.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device such as a bill dispensing machine and a cassette for storing bills and the like.

[0002]

2. Description of the Related Art In a conventional dispensing machine, a bill storage box (hereinafter referred to as a cash cassette) is loaded in a horizontal direction. In order to reduce the depth direction of the device itself, it is only necessary to use the cash cassette in the vertical direction, but if the feeding mechanism is used as it is in the vertical direction, especially when there are many bills, it will be affected by the weight of the bill itself. Unable to stabilize bill feeding / separation.

FIG. 8 shows an example of a cash cassette 2 (shown by a broken line in the figure) loaded in a horizontal direction. In the figure, the bill dispensing machine includes a top unit A (upper part in FIG. 8) for carrying, discharging, and detecting the thickness of a bill, a lower unit B (lower part in FIG. 8) for receiving a cash cassette, and 2
Divided into two parts. In the top unit A, the bills fed from the lower unit B pass through the transport path indicated by the arrow in FIG. Rollers 19a to 19c for transporting bills are provided on this transport path. In the cash cassette 2 in the lower unit B, bills are paid out. In the figure,
The bill is in pressure contact with the feed roller (main) 4a and the feed roller (sub) 4b. Then, the banknotes are fed one by one onto the above-described transport path by the rotation of these feed rollers.

FIG. 8A shows the dimensions (height) of the bill dispensing machine, and b shows the dimensions (depth) of the bill dispensing machine. When a bill dispensing machine is installed, it is better to store as many bills as possible even in the same space, so that the depth b in FIG. For this reason, this bill dispensing machine may be placed vertically.

FIG. 9 is a view showing the appearance of the cash cassette shown in FIG. As shown in the figure, the cash cassette can be opened and closed by a lid (lid) 5 in the arrow direction. As shown by the solid line in the figure, bills are taken in and out with the lid open. Also, the dotted line in the figure shows the position when the lid is closed.

FIG. 10 is a diagram showing the internal structure of the cash cassette of FIG. In the drawing, a cash cassette includes a shutter 6 inside a lid 5, a stacked banknote 12, a pressure 11 for preventing the stacked banknote 12 from scattering and generating a constant feeding pressure, and a tension spring for pulling the pressure in the direction of the arrow. 10. In this tension spring, the number of turns of the spring is increased in order to minimize the load fluctuation of the press.

FIG. 11 shows how the shutter 6 operates when the cash cassette of FIGS. 8 and 9 is inserted into the lower unit B in the direction of arrow a. As shown in the figure, before the shutter 6 is inserted into the lower unit B (that is, when the cassette is alone), the shutter 6 is closed in the oblong hole 14 opened in the lid 5 in the cash cassette. However, when the cash cassette is inserted into the lower unit B (when the cash cassette is set), the stud 8 of the shutter 6 is caught by the bend 9 and the shutter 6 moves in the direction of arrow b. As a result, the shutter 6 opens. Then, the bill and the feed rollers 4a and 4b are pressed against each other.

On the other hand, as described above, the bill dispensing machine may be placed vertically to save space. FIG. 12 and FIG. 13 show problems when the banknote dispensing machine is placed vertically.

FIG. 12 is a diagram showing a problem when the feed roller is located above. In FIG.
1 is pulled by a tension spring 10 in the direction of the arrow. In the case of bill feeding, assuming that the load for pressing the bill against the feed roller is P, the value of P is 500
g to 800 g is said to be optimal. On the other hand, when this bill dispensing machine is used as an ATM, it is said that at least about 2,000 bills need to be stocked.

When this is applied to the same figure, one bill is 1 g.
Therefore, if 2000 sheets become 2000 g and P becomes 500 g to 800 g when 2,000 sheets are stocked, P becomes 500 to
800 g + 2000 g, which is a great feeding load. On the other hand, in order to apply a load P of 500 g to 800 g when the number of sheets is small, the weight becomes 500 to 800 g to 2000 g, and P becomes a downward force, so that the bill is not pressed by the feed roller.

If the capacity is a small number up to about 100, the influence of the weight of the paper money on the number of stored bills is small, and this method is also possible, but it is not used as an ATM. FIG.
FIG. 4 is a diagram showing a problem when a feed roller is below. In the figure, a pressure 11 is pulled by a tension spring 10 by a load P, and presses one end of a stacked bill 12. Here, the pressing force of the feed roller (sub) 4b is N1, and the weight of the stacked bills 12 is N.
2. Assuming that the friction coefficient between the feed roller (sub) 4b and the bill is u1 and the friction coefficient between the bills is u2, the force F required to feed out one bill is F = u1 × N1 + u2 ×
(N2 + P). Here, taking the above ATM as an example, assuming that the cassette has a banknote capacity of 2000, the N2 changes in a range of 0 g (the last one) to 2000 g (at the time of 2000). In this case, FIG.
Unlike the example, the direction of pressing the feed roller does not change. However, since the weight of the stock greatly affects its own weight, the amount of change in the force F required for feeding the bill is large, and a stable bill feeding cannot be expected.

[0012]

In the prior art shown in FIG. 8, the cash cassette is loaded horizontally. For this reason, in order to store a relatively large number of banknotes (about 2,000 in the above example) in a small space, the banknote dispensing machine has to be placed vertically. On the other hand, in the prior art of FIG. 12 and FIG. 13 in which the banknote dispensing machine is installed vertically, the force required to pay out one banknote is not stabilized because the banknote dispensing machine is installed vertically.

FIG. 14 shows a conventional example in which the bill dispensing machine shown in FIG. 12 is improved to stabilize the dispensing of bills. In the figure, the feed roller (main)
4a and the feed roller (sub) 4b are on the upper side of the banknote dispensing machine. One end of the pressure 11 for pressing the stacked banknotes 12 from below is fixed to the timing belt 16a by a connection fitting 18. The timing belt 16a is rotated by an actuator (in this case, the pulse motor 15) to move the pressure 11 up and down. On this occasion,
Active control with pressure detection is performed so that the bill pressing force P to the feed roller becomes substantially constant.

FIG. 15 shows a conventional example in which the bill dispensing machine shown in FIG. 13 is improved to stabilize the dispensing of bills. In addition, the part which overlaps with the description of FIG. 13 will not be repeated.

FIG. 13 differs from FIG. 13 in that
The rubber belt (flat belt) 16b is configured to rotate in conjunction with the pulse motor 15 via the drive connection gear 17. The rubber belt 16b contacts one end of the stacked banknotes 12 and generates an upward force N3 that is opposite to the own weight of the stacked banknotes 12. For this reason,
The force F required to pay out one bill is F = u1 × N1 +
(N2 + P-N3). Here, by rotating the pulse motor 15 by a fixed amount when storing a large number of bills,
The above relational expression holds, and the effect of the own weight N2 is reduced.

As described above, in the conventional examples shown in FIGS. 14 and 15, the purpose of stabilizing the dispensing of banknotes could be achieved to some extent. However, an actuator (motor or the like) was required, so that the weight of the cash cassette could be increased. Costs have increased.

An object of the present invention is to provide a bill dispensing machine having a simple structure and capable of stably dispensing bills.

[0018]

According to the first aspect of the present invention,
In a bill dispensing machine having a detachable cash cassette, a dispensing unit for dispensing bills stored in the cash cassette to the outside, and when inserting the cash cassette into the bill dispensing machine, the insertion operation and And a bill end moving means for moving the end vertically by contacting a part of the stacked bills stored in the cash cassette in conjunction therewith.

According to the present invention, the bill end moving means raises a part of the stacked bills in the vertical direction, for example, upwards the ends, thereby reducing the pressure applied to the feeding means by the weight of the stacked bills. can do. Thus, it is possible to prevent the feeding error from occurring due to an increase in the pressure applied to the feeding means.

Further, the bill end moving means moves in a vertical direction in conjunction with an insertion operation when the cash cassette is inserted into the bill dispenser, and moves a part of the end of the deposited bill. You may comprise so that it may move in the direction which the pressure applied to a delivery means decreases.

Further, the bill end moving means includes a shutter which moves so as to open a bill taking-out portion of the cash cassette when the cash cassette is inserted into the bill dispenser; A moving mechanism that moves in an upward or downward direction in conjunction with the moving mechanism to move a part of the stacked banknotes upward or downward so as to reduce the pressure applied to the feeding means. .

In this way, by providing the moving mechanism that moves in conjunction with the shutter, it is possible to reduce the pressure applied to the feeding means by the deposited bill. Further, the bill end moving means can be realized with a simple structure.

In the cash cassette according to the fourth aspect of the present invention, when the cash cassette is inserted into the bill dispensing machine, the end of a part of the stacked banknotes stored in the cash cassette in conjunction with the insertion operation. A bill end moving means for moving the section in a direction in which the pressure applied to the bill feeding section inside the bill dispensing machine is reduced by the weight of the stacked bills.

According to the present invention, the pressure applied to the pay-out portion can be reduced by the weight of the stacked banknotes, so that occurrence of a banknote pay-out error can be prevented.

[0025]

Embodiments of the present invention will be described below with reference to the drawings. <First Embodiment> FIG. 1 is an external view of a cash cassette according to a first embodiment of the present invention.

In FIG. 1, a cash cassette 2 includes a shutter 6 located inside a lid 5 and a belt (rubber or the like) that rotates clockwise as viewed from the front in conjunction with the shutter 6 to move the stacked bills 12 upward. 28), a pressure 11, a tension spring 10 and the like for preventing bills from being displaced and generating a constant feeding pressure. Further, a shutter fitting 20 attached to the shutter 6 in the figure is newly added in this embodiment. The shutter 6, the rubber belt 28, the rollers 27a to 27d, and the like correspond to the bill end moving means. The operation of the shutter fitting 20 will be described later. In addition, among the operations of the present example, those that are the same as the conventional example are omitted.

FIG. 2 is a view showing a mechanism for moving the end of a bill upward by a rubber belt 28 (hereinafter simply referred to as a mechanism). In the same figure, two sets of rubber belts (flat belts) 28 that act to push up the stacked banknotes 12 by rotating a roller 27a provided inside the belt, a metal fitting 22 that is movable in the vertical direction, A timing belt 30 partially fixed to the metal fitting 22 by, for example, screws is attached to the lid 5 by a plurality of stopper metal fittings 31. 2 and 6 are views of the mechanism viewed from below (that is, from the direction of arrow A in FIG. 1).

FIG. 3 shows a state where the cash cassette 2 is inserted into the bill dispensing machine 1. The transport path shown in the figure shows the path along which the bill is discharged from the bill dispensing machine 1. Rollers 19a to 19c for transporting bills are provided on this transport path.

FIG. 4 is a view showing a state where the insertion of the cash cassette 2 is completed. When this insertion is completed at a certain rate (ie, when the stud 8 is caught in the bend 9 in FIG. 11), the shutter 6
It moves upward with the movement of.

FIG. 5 shows that when the shutter 6 is moved, the shutter fitting 20 attached to the shutter 6 is moved to the fitting 22 (in the mechanism).
Is shown to be raised. When the cash cassette 2 is separated from the banknote dispensing machine 1, the fitting 22 receives a downward force by the tension spring 21 (FIG. 2), and is located at a lower position indicated by a broken line in FIG. When the cash cassette 2 is inserted into the banknote dispensing machine 1, the shutter 6 that rises through the oblong hole 14 in the lid 5.
The shutter fitting 20 attached to the mechanism rises by hooking the fitting 22 attached to the mechanism, and moves to the upper position indicated by the solid line in FIG.

Since the metal fitting 22 is fixed to the timing belt 30, the rollers 29a and 29b of the timing belt 30 rotate with the movement to the upper position. The movement direction of the timing belt 30 is downward when viewed on the bill contact surface side.

On the other hand, the rollers 29a and 29b shown in FIG.
As the gear rotates, the gear pulley 26 fixed to the shaft 32 attached to the roller 29a rotates, and the gear 25 in contact with the gear pulley 26 is rotated counterclockwise when viewed from the right side in FIG. Rotate in the direction. For this reason, the shaft 24 to which the gear 25 is attached rotates, the rollers 27a attached to both ends of the shaft 24 rotate, and the two sets of rubber belts 28 move in the right side view of FIG. , That is, in the counterclockwise direction as viewed from the right side.

The right side surface of the rubber belt 28, which is indicated by a two-dot chain line as the bill contact surface side in the right side view of FIG. 6B, comes into contact with the end of the bill. Therefore, when the rubber belt 28 rotates counterclockwise, the rubber belt 28
Due to the friction between the bill and the end of the bill in contact with the rubber belt 28, a part of the bill is lifted upward in FIG.

FIG. 7 shows that when the cash cassette 2 is inserted into the banknote dispensing machine 1, the rubber belt 28 moves upward in conjunction with the movement of the shutter 6, whereby a part of the end of the stacked banknotes 12 is moved. It shows a state where it is lifted upward.

As described above, since a part of the end of the stacked banknotes 12 is lifted upward by the frictional force with the rubber belt 28, it is applied to the feed roller 4a (FIG. 3) provided below the stacked banknotes 12. The load is reduced, and the deposited banknotes 12
The pressure applied to the feed roller 4a due to the weight and the pressure 11 increases the occurrence of a bill feeding error. The amount of movement of the rubber belt 28 can be adjusted by the gear ratio of the gear 25 and the gear pulley 26 and the like.

As described above, the upward movement of the rubber belt 28 can reduce the influence of the weight of the stacked banknotes.
The subsequent operation of the bill dispensing machine is the same as in the conventional example. That is, one of the stacked banknotes 12 is fed out onto the transport path by the rotation of the feed rollers 4a and 4b. At this time, as shown in FIG. 7, since a part of the stacked banknotes 12 has been lifted, the feeding of each banknote is performed stably. Thereafter, the fed bill is discharged from the bill discharge port 13 through the transport path shown in FIG.

In the above-described example, the metal fitting 22 of the mechanism is fixed to the opposite side of the timing belt 30 from the bill contact surface. For this reason, even if the shutter fitting 20 hooks the fitting 22 of the mechanism and moves to the upper position, the moving direction on the bill contact surface side is downward. The gear pulley 26 and the gear 25 are used to move the movement direction on the bill contact surface side upward.
, Two rubber belts 28 are moved in the opposite direction (upward) to the timing belt 30. However, if the metal fittings 22 of the mechanism are fixed to the bill contact surfaces of the two sets of rubber belts 28 so that the shutter metal fitting 20 moves to the upper position by hooking the metal fittings 22 of this mechanism,
The stacked banknotes can be lifted without using the timing belt 30, the rollers 29a and 29b, and the gear pulley 26. Such a configuration may be adopted. <Second Embodiment> In the present embodiment, the feed roller 4a is located on the upper side of the banknote dispenser which is vertically set, contrary to the first embodiment. The cash cassette is inserted from below the bill dispensing machine. In the second embodiment, in order to reduce the pressure applied to the feed roller 4a provided on the upper portion from the pressure or the like, the stacked bills 12 of the rubber bell 28 are pulled in order to pull some ends of the stacked bills 12 downward. The contact surface moves downward. With such a configuration, even when the feed roller 4a is attached to the upper side of the banknote dispensing machine that is placed vertically, it is possible to stabilize the feeding of the banknotes as in the first embodiment.

In this embodiment, the metal fitting 22 of the mechanism is fixed to the timing belt 30 on the side opposite to the bill contacting surface.
For this reason, even if the shutter fitting 20 hooks the fitting 22 of the mechanism and moves to the lower position, the moving direction on the bill contact surface side is upward. Then, the two sets of rubber belts 28 are connected to the timing belt 3 through the gear pulley 26 and the gear 25 in order to lower the moving direction on the bill contact surface side.
It was configured to move in the opposite direction (downward) from zero. However, the metal fitting 22 of the mechanism is fixed to the bill contact surface side of the two sets of rubber belts 28, and
, The stacked banknotes can be lowered without using the timing belt 30, the rollers 29a and 29b, and the gear pulley 26.

The above-described embodiment has two feeding rollers for feeding bills from the cash cassette to the outside, and the pressure applied to the first feeding roller (feed roller 4a) on the bill feeding port side, that is, The load caused by the stacked banknotes 12 and the pressure 11 above the first feed roller is reduced so that the load applied to the second feed roller (feed roller 4b) is smaller than that of the first feed roller. It is not limited to a plurality. The number of feeding rollers may be one. Also in this case, by lifting the bill ends upward with the rubber belt 28, the weight of the deposited bills 12 above the pay-out roller can be reduced, and the pressure applied to the pay-out roller can be appropriately maintained, so that the bill is stably fed. Can be

Further, in the above-described embodiment, the case where the present invention is applied to a banknote dispensing machine has been described. However, the medium stored in a detachable cassette is not limited to a banknote, Alternatively, a medium other than paper may be used, as long as the medium stored in the cassette is fed out, the present invention can be applied to an apparatus other than the dispenser.

[0041]

As described above, according to the present invention, the dispensing of a banknote in a banknote dispensing machine in which a banknote is stored in a vertical direction is reduced by the weight of the banknote itself and the load due to pressure, thereby stabilizing the feeding of the banknote. Can be done.
