Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet delivery apparatus for taking out paper sheets such as banknotes from an accumulation section of a cash automatic transaction apparatus of a cash flow type.

[0002]

2. Description of the Related Art In a financial institution such as a bank, an automatic teller machine (hereinafter referred to as A) such as an automatic teller machine or an automatic teller machine.
It is called TM. ) Has become remarkable, and nearly 70% of bank branch operations are processed by ATM. AT
M is installed at a mechanized corner of a bank and used for cash withdrawal. Such an ATM has built-in units such as a cassette, a hopper, a temporary storage unit, and the like for handling bills, and these units have a bill extracting mechanism for smoothly sending bills to a transport path.

Conventionally, there are several methods. For example, an elastic body such as rubber having a high friction coefficient is attached to a part of cylindrical aluminum to form a take-out roller, and the take-out roller is synchronized with a timing belt. A method of taking out the accumulated bills by taking out the accumulated bills, or by rotating a roller of an all-around elastic body at a timing when a cam mechanism is provided in a part of the take-out roller, has been adopted.

[0004] The bills fed from the bill take-out mechanism to the transport path detect the length of the bills and the interval between the bills by sensors, and monitor whether the bills are normally conveyed.

[0005]

However, in the apparatus having the above structure, the aluminum portion of the take-out roller is intended to slide the accumulated bills until they are taken out by the elastic portion. Friction is generated even between them. For this reason, the accumulated bills are taken out by the aluminum portion of the take-out roller, causing a conveyance error, or the drive motor loses synchronism due to the torque fluctuation at the time of the take-out roller rotation by the cam mechanism, and it becomes impossible to take out. There's a problem.

Further, conventionally, the sensors are arranged in the vicinity of the take-out / separation section and at a position distant from the separation section. Therefore, when the length of the bill is detected in the vicinity of the separation section, the conveyance speed of the bill is slow, and the sensor detects the bill length. Since the dark time due to the shadow of the bill becomes longer, it is difficult to recognize the state in which the bills remain even when the normal bill extracting operation is performed. Therefore, there is a problem that the length of the banknotes and the interval between the banknotes cannot be detected unless they are located away from the separation unit.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a stacking unit on which paper sheets are stacked, a conveying path on which bills sent from the stacking unit are conveyed, and a paper sheet positioned highest from the stacking unit.

First Embodiment Next, a bill sending method according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 7 is a perspective view showing the bill sending devices provided in the first safe (10,000 yen store) 50, the second safe (10,000 yen store) 51, and the third safe (1,000 yen store) 52, respectively. Is an internal perspective view of the apparatus viewed from the side of a bill transporter, FIG. 9 is a plan view of the apparatus viewed from above, and FIG. 10 is a partial view of a main part of the apparatus viewed from the bill transport direction. is there.

In the figure, the shaded area or the spot area indicates an elastic body G made of rubber, soft resin or the like. Reference symbol B indicates a bearing. Back up and down in each safe 80
Are provided, and the banknotes P are accumulated on the backup 80. The backup 80 rises in response to the delivery of the banknote P, and the topmost banknote P is constantly pressed against the take-out roller 83.

The take-out roller 83 is urged by a pressing spring 82. The take-out roller 8 is formed by the pressing spring 82.
The pressing force and height of No. 3 are variable. In addition, the outer peripheral surface of the take-out roller 83 is covered with an elastic body G having a large coefficient of friction so as not to slip when the bill P is sent out. A first sensor 81 having a light emitting element and a light receiving element is provided at the upper part of the safe, and the detection light is emitted from the upper opening of the safe. This first sensor 8
The optical axis 1 traverses the inside of the safe from the upper side to the lower side of the safe, and it is detected whether or not the banknote P exists in the safe.

A second sensor 95 having a light emitting element and a light receiving element is provided at the exit of the safe. The optical axis of the second sensor 95 crosses the banknote transport path R on the exit side of the safe, and it is detected whether or not the banknote P has passed through the transport path. Further, as shown in FIGS. 8 and 9,
A position detection sensor 84 as a third sensor is provided near the widthwise end of the upper portion of the safe. A shielding plate 85 is provided movably at a position crossing the optical axis of the position detection sensor 84.

The shielding plate 85 is attached to a support mechanism of the take-out roller 83 via a connecting member, and can move integrally with the take-out roller 83. Incidentally, the pressing force of the take-out roller 83 against the uppermost banknote P is determined by the extension of the press spring 82. However, when the optical axis of the position detection sensor 84 is blocked by the shield plate 85 on the take-out roller side, the height of the take-out roller 83 is increased. And the pressing force is kept almost constant.

A belt 101 is stretched between a drive pulley 79b attached to the end of the drive shaft 79a of the motor M and a driven pulley 90b attached to the end of the shaft 90a. Another belt 10 is also provided between the driven pulley 90b and the pulley 83b attached to the end of the shaft 83a.
Two have been bridged. Two idle rollers 87 and four delivery rollers 90 are attached to the shaft 90a at substantially the same pitch so that they can rotate coaxially. Each idle roller 87 is connected to a shaft 90a via a bearing B so as to be able to idle.

On the other hand, each delivery roller 90 is fixedly connected to a shaft 90a, and rotates together with the shaft 90a. An elastic body G having a large coefficient of friction is provided on the outer peripheral surface of each delivery roller 90 for slip prevention.
The roller 90 is prevented from slipping over the banknote P at the time of feeding. In this embodiment, the two idle rollers 87 are alternately arranged between the four delivery rollers 90, but a different number of rollers 87, 9 are used.
0 may be arranged differently.

The take-out roller 83 and the timing pulley 88 are connected and fixed to the shaft 83a. The rollers 83 and 90 are alternately arranged (nested arrangement) such that the take-out rollers 83 are located between the delivery rollers 90, respectively. The timing pulley 88 is disposed on the same axis 83 a as the take-out roller 83 and immediately before the separating portion. A timing belt 89 is stretched between the timing pulleys 88.

The outer circumference of the take-out roller 83 and the idling roller 8
A part of the surface of the floor guide 86 is provided on a tangent line connecting the floor guide 7 with the floor guide 86. This is because if there is a gap between the floor guide 86 and the banknote P, in the case of a banknote without stiffness, the banknote P cannot easily withstand the tangential force and is easily buckled in the gap, which may cause a jam. It is because it becomes. As shown in FIG. 8, press-contact rollers 91 are arranged directly below the idle rollers 87, respectively. The peripheral surface of each pressure roller 91 is pressed against the peripheral surface of the idling roller 87. Each pressing roller 91 is fixed to a support shaft 91a so as not to rotate. Further, the peripheral surface of the pressing roller 91 is covered with an elastic body G having a large friction coefficient. The pressing force of the pressing roller 91 is given by a pressing spring 93 attached to a support arm 92.

The separation unit includes an idling roller 87 which is coaxial with the delivery roller 90 and freely rotates with respect to the shaft 90a;
The pressing roller 91 is located immediately below the pressing roller 91. The surface of the idling roller 87 is finished with low friction using the bearing itself or resin. On the other hand, the pressing roller 91
The outer periphery is covered with an elastic body such as rubber, and is pressed against the idling roller 87 by a pressing force of a pressing roller pressing spring 93 via right and left independent support arms 92 to prevent contact.

As shown in FIG. 10, two abutment members 92b are fitted into the support shaft 92a of the support arm 92, and each abutment member 92b is pressed against the peripheral surface of the pressure roller 91. I have. When the uppermost banknote P1 is taken out of the stacking unit, only the second banknote P2 to be sent to the separation unit together with the uppermost banknote P1 and the one-way clutch reversely rotates (rotation in the direction opposite to the banknote transport direction). A large frictional force is generated between the pressing roller 91 and the second and subsequent bills P2 so that the bills P2 are pushed back toward the stacking unit.

Further, the pinch roller 94 is
1 and on the transport path R on the safe exit side. The peripheral surface of the pinch roller 94 is in contact with the peripheral surface of the delivery roller 90. The tip of the uppermost banknote P1 is pinched by the pinch roller 94 and the delivery roller 90, and only the uppermost banknote P1 is sent out toward the transport path R.

The uppermost banknote P1 slides on the outer peripheral surface of the idling roller 87 while passing through the separating portion while lifting the pressing roller 91, and is then sandwiched between the sending roller 90 and the pinch roller 94 and sent out to the transport path by the pulling output. Although the distance of the pinch roller 94 from the take-out roller 83 is shortened, the bill P is pulled from the front by the pulling force of the pinch roller 94 and the delivery roller 90, rather than being pushed from behind by the tangential force of the take-out roller 83. This is advantageous for buckling. Then, the take-out roller 83 is moved to the delivery roller 90.
And an idler roller 87 having a nested structure.
And the distance between the pinch rollers 94 are reduced.

Next, the operation of the above-mentioned bill sending device will be described. First, the transport system is driven by the motor before taking out the stacked banknotes P. The delivery roller 90 receives a driving force from the transport system, and makes the transport speed on the circumference of the outer diameter of the transport roller the same as that of the other transport systems. While the transport system is being driven, the delivery roller remains rotating.

When the stacked banknotes P on the backup 80 are detected by the first sensor 81, the take-out roller 83, whose pressing and height can be varied by the pressing spring 82, is driven by the motor M via the timing belt 89, Mogami Banknote P
A tangential force is applied to 1 and sent toward the separating section. The pressing force of the take-out roller 83 against the uppermost banknote P1 is a pressing spring 82.
The position detection sensor 84 is shielded by the shielding plate 85 on the take-out roller side, so that the take-out roller 8
The height of 3 is maintained, and the pressing force is kept almost constant.

At this time, the floor guide 86 and the uppermost banknote P1
If there is a gap between the paper roller and the stiff paper money, the banknote will not be able to withstand the tangential force and will buckle in this gap to cause a jam.
Since a part of the surface of the floor guide 86 is provided on a tangent line connecting the outer diameter circumference to the outer circumference, no jam occurs. Further, a timing pulley 88 is disposed on the take-out roller shaft 83a and immediately before the separation portion, and a timing belt 89 is stretched between the pulleys 88. The timing belt 89 is driven in synchronization with the take-out roller 83 to further buckle. The prevention effect can be realized.

In the separation section, the pressure roller 91 is driven by an input gear 96 having a built-in one-way clutch to pulleys 97a and 97a.
7b and the belt 98 to rotate in the reverse direction (rotation in the direction opposite to the bill transport direction), and large friction is generated between the pressing roller and the second and subsequent bills P2.
Thereby, the second and subsequent banknotes P2 are separated from the uppermost banknote P1, and only the uppermost banknote P1 is sent out toward the transport path R.

The uppermost bill slides on the outer peripheral surface of the idling roller 87 while passing through the separating portion while lifting the pressing roller 91, and is then sandwiched by the delivery roller 90 and the pinch roller 94.
The output is sent to the transport path. At this time, the uppermost banknote P1 pulled out while being sandwiched between the delivery roller 90 and the pinch roller 94 is detected by the sensor 95, and the takeout roller 83, which has accelerated and rotated to feed the uppermost banknote P1 to the separation unit, is stopped. The take-out roller 83 is the banknote P2 next to the uppermost banknote (the banknote that becomes the highest banknote after P1)
Is kept stopped until the next take-out timing (intermittent rotation) in order to prevent P2 from entering the separation section due to the frictional force between the banknotes P1 and P2.

The above operation is repeated, the number of bills P to be sent out is counted by the second sensor 95 as the take-out detecting means, and when the counted number reaches the specified number, the bill feeding operation is stopped. Second Embodiment Next, a second embodiment of the present invention will be described with reference to the drawings.

FIG. 11 is a plan view of the bill transporting device of the second embodiment as viewed from above. The description of the same configuration as that of the first embodiment is omitted, and the same reference numerals are used. In FIG. 11, reference numeral 83c denotes a take-out roller with a built-in one-way clutch which incorporates a one-way clutch and freely rotates in a forward rotation (rotation in the same direction as the bill conveying direction). The take-out roller 83c with a built-in one-way clutch corresponds to the left and right outside take-out rollers of the three take-out rollers 83 in the first embodiment.

According to such a configuration, the uppermost banknote P taken out is supported by the delivery roller 90 and the pinch roller 94, and when the topmost banknote P is taken out from the stacking section, the takeout roller 83 is taken out.
Functions as a stopper so that the two-day banknote P2 does not enter the separation unit. However, since the left and right take-out rollers 83c rotate while the uppermost banknote P1 is in contact with the take-out roller, paper having a particularly high friction coefficient is used. With respect to the leaves, the extraction state can be further stabilized.

Other operations are the same as in the first embodiment. Third Embodiment Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 12 is a perspective view showing the bill sending devices provided in the first safe (10,000 yen store) 50, the second safe (10,000 yen store) 51, and the third safe (1,000 yen store) 52, respectively. Fig. 1 is an internal perspective view showing the same apparatus as viewed from the side of a bill transport bribe,
4 is a plan view of the same device as viewed from above. FIG. 1 is a view of a main part of the apparatus viewed from a bill conveying direction.
Since it is the same as 0, the description is omitted. The description of the same configuration as that of the first embodiment is omitted, and the same reference numerals are used.

In the drawing, reference numeral 95b denotes a sensor as extraction detecting means, and the sensor 95b is provided with a pinch roller 94.
Immediately after and at a distance from the lower part of the take-out roller 83 to a distance equal to or longer than the short side of the bill. With such a configuration, the trailing end of the taken-out bill goes out of the take-out roller, and the bill at the same speed as the transport speed can be regarded as a detection target, so that the detection can be performed stably.

By the same operation as in the first embodiment, the operation of sending the uppermost banknote to the transport path and then detecting the banknote by the sensor 95b is repeated.
Is counted, and when the counted number reaches the specified number, the bill feeding operation is terminated. In addition,
In the first to third embodiments, an example in which the present invention is applied to an automatic cash transaction apparatus has been described. Applicable.
