Description

Bill stacking device {Apparatus for stacking paper money}

The present invention relates to a banknote accumulating device, and more particularly, to a banknote accumulating device capable of stably accumulating banknotes in a banknote accumulating space.

In general, a banknote accumulating device is a device installed in an automated financial machine to accumulate banknotes, checks, and other accumulation objects having a predetermined thickness (hereinafter collectively referred to as 'banknotes') in a banknote accumulating space. Such banknote accumulators are used in deposit and withdrawal units, temporary storage units, banknote storage units, and the like of automated financial machines.

Referring to FIGS. 1 and 2, on one lower side of the conventional banknote accumulator 1, a configuration for accumulating banknotes P transported along the conveyance path 10 into the banknote accumulating space 30, conveying A feed roller 21 and a gate roller 22 installed to face each other on both sides of the furnace 10, and sandwiched between the feed roller 21 and the gate roller 22 to enter one side of the bill accumulating space 30 An accumulation unit 20 including a stack roller 23 to which a plurality of elastic sheets 23a are attached for stacking the banknotes by hitting the rear end of the banknotes P is installed.

The banknote accumulating space 30 is provided with a push plate 40 for supporting banknotes P to be accumulated, and one side of the banknote accumulating space 30 is provided with the banknotes P entering the banknote accumulating space 30. A front plate 50 is provided to prevent flying.

The front plate 50 is provided so as to be rotatable at a predetermined angle around the rotating shaft 61, and pushes the bill P, which has entered one side of the bill accumulating space 30, to the other side of the bill accumulating space 30. A stopper 60 is provided to press and support the plate 40 side. The stopper 60 stacks banknotes while repeating a rotational movement operation between a home position shown in a dotted line and a stack position shown in a solid line in FIG. 2 .

The stopper 60 is configured to overlap with the push play 40 in order to fix and support the bill P when in contact with the push play 40 . Here, 'overlapping' means that the stopper 60 is rotatable by a predetermined angle further in the direction toward the push plate 40 than the position where the stopper 60 actually contacts the side surface of the push plate 40, as shown by the dotted line in FIG. 2 ( 60) means that the rotation range is set. The reason why the stopper 60 and the push plate 40 are set to overlap in this way is to more stably hold and support the bill P between the push plate 40 and the stopper 60 .

However, when the banknotes entering the banknote accumulating space 30 are supported by being held between the push plate 40 and the stopper 60, as shown in FIG. 2, initially when the banknotes P are accumulated, the stopper The front plate 50 vibrates up and down due to the reaction force due to the overlap of the 60 and the push plate 40, and when the bill P enters, the front plate 50 moves backward (right side with reference to FIG. 2). A phenomenon of being pushed out and lifted from the push plate 40 occurs, and in this case, there is a problem that acts as a factor of stack misalignment because the entering banknote P is not properly held.

Among the prior art, a damper (not shown) is installed on the front plate 50 to prevent the upward movement of the banknotes at a stage before the banknotes are clamped by the stopper 60, so that the banknotes can be accumulated more stably. Although proposed, such a structure has a damper installed on the front plate 50, so when the front plate 50 is pushed backwards, the damper also moves backward along with the front plate 50, so it is limited in stably supporting the bill. There is a problem with

A front plate 150 for guiding to be loaded into the collecting space 130, and a front plate 150 rotatably provided in a predetermined angular range to transfer bills entering one side of the bill accumulating space 130 into the bill accumulating space ( 130), a stopper 160 that presses and supports the push plate 140 located on the other side, and is provided on one side of the push plate 140 opposite the stopper 160 to the banknote accumulating space 130 Damper 170 for preventing the front plate 150 from being pushed to the opposite side of the bill collecting space 130 by the impact by absorbing the impact of the stopper 160 that presses the bill entering into) include

In addition, the banknote collecting device 100 of the present invention includes a banknote detecting unit 180 for detecting whether or not banknotes conveyed toward the collecting unit 120 along the conveying path 110 pass, and the stopper 160 The stopper detecting unit 162 for detecting the rotated position, and the collecting unit 120 and the stopper driving unit 163 based on the signals detected by the banknote detecting unit 180 and the stopper detecting unit 162 It is configured to further include a control unit 190 for controlling driving.

The stopper driving unit 163 drives the stopper 160 to be rotated to a stack position facing the bill accumulating space 130 and to a home position located inside the front plate 150 by avoiding the bill accumulating space 130 By doing, it is configured to include a motor (not shown) that is rotated in both directions and a power transmission means such as a belt (not shown) that transmits the power of the motor to the rotational shaft 161 of the stopper 160. can

The collecting unit 120 is a structure for stacking bills transported along the conveying path 110 and entering one side of the bill accumulating space 130 into the bill accumulating space 130, A feed roller 121 and a gate roller 122 are provided on opposite sides to transfer bills therebetween, and are coupled to the same axis as the gate roller 122 and enter the bill accumulating space 130 on the outer circumferential surface. It is configured to include a stack roller 123 to which a plurality of elastic sheets 123a that hit the rear end of the banknote are attached.

The stack roller 123 is rotated to enter the bill accumulating space 130 while the bill entering the bill accumulating space 130 is held between the stopper 160 and the damper 170 and supported. The lower end of the bill is moved toward the push plate 140.

The push plate 140 is provided to move left and right in response to an increase or decrease in the number of banknotes accumulated in the banknote accumulating space 130 . That is, when the number of bills accumulated in the bill accumulating space 130 is small, the push plate 140 is located on one side (right side in FIG. 3) of the bill accumulating space 130 and is accumulated in the bill accumulating space 130. As the number of banknotes increases, it is moved to the other side (left side in FIG. 3) of the banknote accumulating space 130 so that a space in which banknotes can be loaded is secured.

The front plate 150 prevents the bill P entering the bill accumulating space 130 at high speed from being blown upward by the feed roller 121 and the gate roller 122, and prevents the bill from moving toward the bill accumulating space 130. ) It serves to guide to be guided to the side of the push plate 140 in the. The arrangement of the front plate 150 is arranged to have an upward inclination from the lower end located on one lower side of the bill accumulating space 130 to the upper end located on one upper part of the bill accumulating space 130. Accordingly, the front end of the bill passing through the feed roller 121 and the gate roller 122 can be guided along the front surface 151 of the front plate 150 toward the push plate 140 side.

When the bill enters one side of the bill accumulating space 130, the stopper 160 presses the bill toward the push plate 140 located on the other side of the bill accumulating space 130 to temporarily hold the bill, It works to prevent flying.

The stopper 160 has one end connected to the rotational shaft 161 provided on the front plate 150, and rotates between the home position shown in dotted lines in FIG. 3 and the stack position shown in solid lines By repeating the operation, the banknotes are stacked.

The stopper 160 is provided so as to be rotatable in a direction toward the bill accumulating space 130 and in a direction avoiding the bill accumulating space 130 based on the front surface of the front plate 150 .

The stopper 160 is located on the inside of the front plate 150 by being avoided from the bill collecting space 130 at a stage before the bill enters the bill accumulating space 130, and When the bill enters, it is rotated toward the front of the front plate 150 to press the bill toward the push plate 140.

The stopper 160 overlaps so that the banknotes entering the banknote accumulating space 130 are rotated further by a predetermined angle in the direction toward the banknote collecting space 130 than one side of the push plate 140. quantity is set. Here, 'overlap' means that the rotation range of the stopper 160 is set so that the stopper 160 can rotate a predetermined angle further in the direction toward the push plate 140 than the position where the stopper 160 contacts the side surface of the push plate 140. it means there is This is to more stably hold and support the bill P between the push plate 140 and the stopper 160 .

The damper 170 is provided at a portion where the stopper 160 comes into contact with the end of the stopper 160 when the stopper 160 is rotated to the stacked position, and the shock generated when the stopper 160 contacts the side surface of the push plate 140 is reduced. As a configuration for absorbing and simultaneously absorbing the amount of overlap set in the stopper 160, the stopper 160 may be displaced in the pressing direction by the amount of overlap of the stopper 160.

The damper 170 may be made of an elastic material. In an embodiment, the damper 170 may be made of a material such as rubber, silicone, polyurethane, or the like.

In addition, the damper 170 may be supported by an elastic member 171 that applies an elastic force in a direction opposite to the direction pressed by the stopper 160 . In this case, when the stopper 160 is rotated to the stacked position to press the damper 170, the damper 170 is pushed in the direction in which the stopper 160 is pressed by the pressing force of the stopper 160 and is displaced a predetermined distance, and the elastic member Shock is absorbed by the contraction deformation of 171, and when the stopper 160 is rotated back to the home position, the damper 170 is returned to its original position by the restoring force of the elastic member 171.

In this way, the damper 170 for compensating for and buffering the amount of overlap of the stopper 160 is provided on the push plate 140 where the stopper 160 touches, and as shown in FIG. 5, at the initial stage of accumulation of bills By preventing the front plate 150 from vibrating and being pushed backward, the banknotes P can be stably supported and stacked in an aligned state in the banknote collecting space 130 .

6 shows a state in which banknotes P2 enter through the banknote collecting unit 120 in a state where banknotes P1 are accumulated in the banknote collecting space 130. In this case, the banknote collecting space 130 Since the impact force and the amount of overlap of the stopper 160 are absorbed by the bill P1 accumulated in the stopper 160, vibration of the front plate 150 and pushing backward when the stopper 160 rotates to the stack position even if it is not by the action of the damper 170 phenomena can be prevented.

On the other hand, the banknote detection unit 180 is a configuration for detecting whether or not bills conveyed toward the banknote collecting space 130 along the transport path 110 pass or not, and may be composed of an optical sensor composed of a light emitting unit and a light receiving unit. In addition, various sensing means for detecting whether bills pass may be employed.

The control unit 190 determines the passing time of the rear end of the banknote detected by the banknote detection unit 180, the transport speed of the banknote in the transport path 110, and the banknote entry part of the banknote detection unit 180 and the banknote collecting space 130. The driving of the stopper driving unit 163 is controlled based on the distance between the stops. Here, in the case of using the passing time of the rear end of the banknote as a reference, regardless of the difference in the length of the banknote according to the denomination of the passing banknote, the collecting unit 120 and the stopper driving unit 163 are driven based on the passing time of the rear end of the banknote By doing so, it is possible to control the hitting point and the hitting point of the rear end of the banknote by the stack roller 123 to be constant, and the rotational position of the stopper 160 can be accurately controlled.

In the step before the bill P enters the bill accumulating space 130, the stopper 160 is avoided from the bill accumulating space 130 and is located inside the front plate 150, and in the bill accumulating space 130 At the point in time when the banknote enters, the stopper 160 is rotated toward the front of the front plate 150 to press the entered banknote P toward the push plate 140. In this case, the upper end of the banknote P2 is between the damper 170 and the stopper 160 (see FIG. 5) or between the banknote P1 and the stopper 160 already accumulated in the banknote collecting space 130 (see FIG. 6) ) and becomes temporarily stopped. At the same time, the bill P2 hit by the elastic sheet 123a of the stack roller 123 is moved laterally toward the push plate 140 and can be stably accumulated in the bill collecting space 130 . Therefore, even in the case of stacking bills of different types having different lengths, it is possible to effectively prevent bills from flying, thereby improving the stacking quality of bills.

As described above, the present invention is not limited to the above-described embodiments, and modifications obvious to those skilled in the art to which the present invention pertains may be carried out without departing from the technical spirit of the present invention claimed in the claims. It is possible, and such modifications fall within the scope of the present invention.
