The present invention relates to an automatic teller machine, and more particularly, to an automatic teller machine equipped with a multi-function cam driver capable of driving various movable parts.

Financial automated devices are automated devices that can provide basic financial services, such as deposit or withdrawal, without the need for bank employees, regardless of time and place.

The automated teller machines can be divided into cash dispensers and cash dispensers according to whether or not they are withdrawn.In recent years, the automated teller machines have been used for various purposes such as cash withdrawals, check deposits, bank accounts, payment of giro fees, ticket releases, etc. have.

In general, the automated teller machine picks up and transfers the paper medium from the paper medium storage unit by sheet unit, and the transferred paper medium is immediately moved to the withdrawal unit or temporarily stored in the temporary stack unit and then to the withdrawal unit. In the case of using the temporary stack unit, the paper medium may be provided to the customer in stack units.

Such automatic teller machines are provided with various movable parts such as a temporary stack part, a carriage for transporting paper media, and a media outlet, and if the respective automatic drive parts must be provided to drive the various movable parts, the structure of the automated teller machine becomes complicated. There is a problem that is difficult to maintain.

Therefore, the necessity of driving various movable parts of the automated teller machine with as few driving parts as possible is increasing.

The present invention has been made to solve the problems of the prior art as described above, the present invention provides a financial automation device having a multi-function cam drive that can drive a variety of movable parts using a single cam drive.

The present invention provides a financial automation device having a multi-function cam driving unit that is simple in the drive structure of the movable portion and can easily perform a failover.

The cam driver may provide a financial automation device that provides a driving force for opening and closing the media outlet.

By constructing as described above, it is not necessary to provide a lot of driving parts because various movable components can be moved using one cam driving part.

The cam driving unit may include a first driving groove for providing a driving force to the shutter unit for opening and closing the media outlet on one surface and a second driving groove for elevating the temporary stack unit on the other surface. Therefore, the shutter can be opened and closed by using one surface of the cam driving portion, and the temporary stack portion can be elevated by using the other surface.

Here, the first driving groove may be formed as an arc-shaped curved groove having the same radius at the center of rotation along the rotation direction of the cam driving part. Since the first driver has the same rotation radius, the shutter can be opened and closed along a predetermined path.

The shutter unit may include a shutter for opening and closing the media outlet, and a shutter bracket connecting the shutter and the first driving groove to receive the rotational force of the cam driving unit to operate the shutter. In this case, shutter slots may be formed on both sides of the shutter bracket to open and close the shutter as the shutter bracket moves.

By configuring in this way, the shutter which is separated from the cam drive part can be driven, and the rotation force of a cam drive part can be converted into linear motion, and a shutter can be opened and closed.

The second driving groove is a spiral or spiral-shaped curved groove in which the radius at the center of rotation gradually increases or decreases along the rotational direction of the cam driving portion, and one end of the curved groove is at the rotation center of the cam driving portion rather than the other end. Can be formed closer. For this reason, the temporary stack portion can be driven up and down with a predetermined height difference.

The temporary stack unit may further include a damping module that may vary a collision distance of the paper medium entering when the paper medium is received from the carriage transfer unit, and the damping module may have a variable collision distance by the cam driver. To this end, the damping module includes a damping rail formed on the temporary stack portion, a movable portion moving along the damping rail and a driving shaft connected to the movable portion to move the movable portion, and at one end of the driving shaft inside the cam driving portion. A lever driven by the formed ribs can be formed. One end of the paper medium may be neatly aligned regardless of the size of the paper medium loaded on the temporary stack by the damping module.

The temporary stack part may further include a cover covering the upper opening when the paper medium is received from the carriage transfer part, and the cover may be driven by the cam driving part. Here, a guide pin is formed on the outer circumferential surface of the cam driving part toward the inner side of the cam driving part, and the guide pin may move along the cam guide connected to one end of the cover and drive the cover. By configuring in this way, the opening part of a temporary stack part can be opened and closed using a cam drive part without a separate drive part.

As described above, the present invention can reduce the production cost and improve the productivity by simplifying the structure of the drive unit of the automated teller machine by using a single cam drive unit capable of driving various movable parts.

Since the present invention drives several movable parts using one multi-function cam driver, even if a failure occurs in the power transmission system of the movable part, the present invention can easily cope with the maintenance convenience.

The paper medium picked up and supplied from the medium storage unit 120 is transferred to the temporary stack unit 140 through the medium transfer device 130. A temporary stack unit 140 is formed at a position adjacent to the outlet of the medium transporting device 130. In the temporary stack unit 140, paper media are stacked one by one and a stack of paper media is made.

Referring to FIG. 1, the temporary stack part 140 according to an exemplary embodiment of the present invention includes a support 142, a front partition 144, a rear partition 143, and a stack lift part 146 and 200. Here, the stack lift part includes a rotation support 146 and a cam driver 200 which is rotationally driven. The support 142 may move up and down through the pivoting movement of the rotation support 146. That is, the support 142 may be located adjacent to the outlet of the media transport device 130, it may be in a position to move up for the carriage 150 switch.

On the other hand, it may include a motor (not shown) for driving the cam driving unit 200.

The cam driving unit 200 may be formed with a spiral second driving groove 206 of varying radius according to the rotation angle, the projection 147 is coupled to the second driving groove 206 in the rotary support 146. Can be formed. Accordingly, when the cam driving unit 200 rotates in the clockwise direction with reference to the drawings, the rotation support 146 rises. On the contrary, when the cam driving unit 200 rotates counterclockwise, the rotation support 146 descends.

The carriage 150 is provided in a structure that can partially overlap the support 142 of the temporary stack unit 140, and may be generally provided in a fork shape having a plurality of supports.

When the support 142 rises upward, the carriage 150 may move forward, and the lower portion of the carriage 150 may be inserted into the support 142 to be positioned below the paper medium.

In addition, the carriage transfer unit 170 is provided on the top or both sides of the carriage 150. The carriage transfer unit 170 is for pressing the upper surface of the paper medium or the stack at the same time as the carriage 150 is transferred, it is possible to ensure that the paper medium is neatly conveyed.

Can be maintained.

The force for transferring the stack of paper media to the media outlet 115 is the driving force of the carriage 150 and the belt 172, and the belt 172 also serves to press the upper surface of the paper media. That is, the bundle of paper media is not transferred due to the friction force between the belt 172 and the paper media stack.

In addition, when a paper medium that is not withdrawn or received by the customer remains in the carriage 150, the paper medium should be separated from the carriage 150 and collected. For this purpose, the paper medium pivots in the forward direction of the carriage 150. The stopper 180 may be formed on the transport path of the carriage 150. When the carriage 150 is advanced, the paper medium loaded on the carriage 150 is not caught by the stopper 180. When the carriage 150 is retracted, the paper medium loaded on the carriage 150 is caught by the stopper 180. The paper medium is separated from the carriage 150.

Hereinafter, the operation of the automated teller machine 100 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4.

As shown in FIG. 2, when a desired amount of paper medium is accumulated on the support 142 of the temporary stack unit 140, the cam driving unit 200 may rotate clockwise to raise the support 142. At this time, the paper medium stacked on the support 142 is in contact with the bottom surface of the carriage transfer unit 170, and maintained in a state arranged by the belt 172.

Referring to FIG. 3, the carriage 150 moves forward toward the media outlet 115 so that the lower portion of the carriage 150 may enter the inside of the support 142, and the cam driving unit 200 may be reversed. When the support 142 is rotated to descend, only the paper medium remains in the carriage 150, and the other temporary stack unit 140 continues to descend.

As a result, the paper medium is transferred to the carriage 150, and the carriage 150 continues to advance toward the media outlet 115.

Referring to FIG. 4, the carriage 150 may move to the media outlet 115 together with the paper medium by the carriage transfer unit 170. At this time, even if the carriage 150 meets the stopper 180, the carriage 150 may move forward while pushing the stopper 180. That is, the stopper 180 opens the conveyance path of the carriage 150 by pivoting in the forward direction of the carriage 150 by the carriage 150.

As described above, all of the components moving in the automatic teller machine 100 according to the embodiment of the present invention, that is, the temporary stack unit 140, the media outlet 115, and the like, which are movable units, are all driven by the cam driving unit 200. It works by That is, the bar driving unit 200 according to an embodiment of the present invention may be referred to as a multi-function cam driving unit by driving various movable units using one cam driving unit 200. Hereinafter, the structure of the cam driving unit 200 will be described in more detail with reference to the accompanying drawings.

FIG. 5 is a perspective view illustrating an upper structure of the automated teller machine according to FIG. 1, FIG. 6 is a side view of FIG. 5, and FIGS. 7A to 7D are views illustrating a cam driver according to FIG. 5.

5 and 6, the upper structure of the automated teller machine 100 according to an embodiment of the present invention is a frame 111 for accommodating various components therein, the shutter provided on the upper side of one side of the frame 111 It may include a cam driver 200 mounted on one side of the bracket 112 and the frame 111.

The components provided inside the frame 111 may be provided at the rear side of the frame 111 and include a carriage transfer part 170 including a plurality of shafts (not shown), rollers (not shown), and a belt (not shown), There is a carriage 150 driven by the carriage transfer unit 170 and a temporary stack unit 140 for forming a stack of paper media to be transferred to the carriage 150. The end of the rotation support 146 of the temporary stack unit 140 is rotatably mounted on the inner surface of the frame 111.

The cam driving unit 200 provided on one outer surface of the frame 111 has a disc shape having a predetermined thickness and is connected by the cam driving motor 250 and the belt 252 spaced apart from the cam driving unit 200. The driving force is transmitted from the cam driving motor 250.

The driving force of the cam driving motor 250 is transmitted to the cam driving unit 200 through the belt 252, so that the cam driving unit 200 rotates, and as the cam driving unit 200 rotates, various types of cam driving units 200 are connected to the cam driving unit 200. Components can also have a constant movement.

First, the cam connecting portion 112a of the shutter bracket 112 may be connected to the outer surface of the cam driving unit 200. Here, the cam connecting portion 112a is not fixed to the outer surface of the cam driving unit 200 but is formed to move along the path formed on the outer surface of the cam driving unit 200 as the cam driving unit 200 rotates.

The shutter bracket 112 is provided to cover an upper portion of one side of the frame 111, and a shutter 116 for opening and closing the media outlet 115 may be connected to one end of the shutter bracket 112. At this time, the shutter 116 may move along the shutter slot 112b formed in the shutter bracket 116. That is, when the cam driving unit 200 is further rotated while the cam driving unit 200 is rotated so that the cam connecting unit 112a is positioned at one end of both ends of a path (not shown) formed on the outer surface of the cam driving unit 200. Since the cam connection part 112a is also rotated while being caught at the path end of the cam driving part 200, the shutter bracket 112 may move. When the shutter bracket 112 is moved, the shutter 116 connected through the shutter slot 112b is also moved. In this process, the shutter 116 may open and close the media outlet 115.

Here, the shutter slot 112b may be formed in two stages. That is, it may be formed to have an upper horizontal portion and a lower horizontal portion and the inclined portion connecting the two. When the cam driving unit 200 rotates while the cam driving unit 200 is retracted while the shutter 116 is positioned at the end of the shutter slot 112b, the shutter 116 is positioned above the shutter slot 112b and the media outlet. 115 may be opened.

Since the distance between the media outlet 115 and the cam driver 200 is far, a shutter bracket 112 is required to transmit the driving force of the cam driver 200 to the shutter 116, and the shutter bracket 112 is a cam driver ( The rotational force of the 200 may be converted into a linear motion and the shutter 116 may be operated in the vertical direction.

On the other hand, the outer surface of the frame 111 is provided with a cam guide 230, the cam guide 230 is a slot 111a of the frame 111 by a guide pin (not shown) formed on the outer peripheral surface of the cam driving unit 200 The cover (not shown) covering the upper opening of the temporary stack unit 140 may be moved when the paper medium is loaded on the temporary stack unit 140 along ().

As such, the belt 252 is fastened to receive power through the outer surface of the cam driving unit 200, and the shutter 116 may be opened and closed by the received power. The temporary stack 140 or the damping module (not shown) may be driven through the inner surface of the cam driver 200.

7 (a) is a perspective view showing the outer surface of the cam driving unit, FIG. 7 (b) is a perspective view showing the inner surface of the cam driving unit, FIG. 7 (c) is a front view showing the outer surface of the cam driving unit, FIG. 7 (d) is a rear view showing the inner surface of the cam drive unit.

Referring to (a) and (c) of FIG. 7, the gear part 202 may be connected to the circumferential outer circumferential surface of the cam driving part 200 so that the belt 252 receiving power from the cam driving motor 250 may be fastened. The first driving groove 204 for driving to open or close the shutter 116 may be formed on an outer surface thereof. Meanwhile, a center of rotation 201 is formed at the center of the cam driver 200 so that the cam driver 200 may be rotatably mounted to the frame 111.

Here, the first driving groove 204 is formed in a groove shape on the outer surface of the cam driving unit 200, the cam connecting portion 112a of the shutter bracket 112 is seated on the first driving unit 204 of the groove shape. The cam connecting portion 112a rotates along the first driving groove 204 as the cam driving unit 200 rotates. In other words, as the cam driving unit 200 rotates, the cam connecting unit 112a is still and the first driving groove 204 rotates. When one end of both ends of the first driving groove 204 meets the cam connection part 112a as the cam driving part 200 rotates, the shutter bracket 112 may move from that time.

Both ends 204a and 204b of the first driving groove 204 are separated from each other. That is, the first driving groove 204 is not formed in a closed curve shape. When both ends of the first driving groove 204 are connected to each other, the shutter 116 may not be closed when the shutter 116 is open, and may not be opened when the shutter 116 is open. This is because the cam connection part 112a is caught and there is no part that can be driven together with the cam driving part 200.

The first driving groove 204 may be formed to have the same radius of curvature as the outer circumferential surface of the cam driving unit 200. That is, the first driving groove 204 is formed to have an arc-shaped curved groove having the same radius with respect to the rotation center 201 in the rotation direction of the cam driving unit 200. Here, both ends 204a and 204b of the first driving groove 204 may be formed on the same side with respect to an imaginary line (that is, a diameter line) passing through the rotation center 201. The cam driving unit 200 according to the present invention may open and close the shutter 116 by the first driving groove 204 formed on the outer surface.

The driving force may be provided to the shutter unit including the shutter bracket 112 and the shutter 116 by the first driving groove 204 formed on one surface of the cam driving unit 200.

On the outer surface of the cam driver 200, a manual driver 208 connected to the rotation center 201 of the cam driver 200 may be formed. The manual driving unit 208 rotates the cam driving unit 200 even when the jam of the paper medium occurs, even when the cam driving motor 250 driving the cam driving unit 200 is turned off. That is, the manual driving unit 208 is for forcibly rotating the cam driving unit 200 in the emergency. When the jam occurs or the cam drive motor 250 is broken, the user may forcibly turn the manual driving unit 208 by hand to remove the jammed paper medium.

Meanwhile, referring to FIGS. 7D and 7D, a second driving groove 206 for elevating the temporary stack part 140 may be formed on the inner surface of the cam driving part 200. The second driving groove 206 may be intaglio formed on the outer surface of the cam driving unit 200. For this reason, the temporary stack 140 may be elevated by using the inner surface of the cam driving unit 200.

The second driving groove 206 may be formed so that both ends are separated from each other. When both ends 206a and 206b of the second driving groove 206 are connected to each other, the temporary stack 140 may not rise when the temporary stack 140 descends along the second driving groove 206, or may not fall when raised.

Unlike the first driving groove 204, the second driving groove 206 may be formed to have a non-uniform radius of curvature. That is, the second driving groove 206 is a spiral or spiral-shaped curved groove in which the radius at the center of rotation 201 gradually increases or decreases along the rotation direction of the cam driving unit 200, and one end of the curved groove is the other end. It may be formed closer to the rotation center 201 of the cam driving unit 200 than.

An end near the outer circumferential surface of the cam driving unit 200 among the both ends 206a and 206b of the second driving groove 206 is called an rising end 206a and an end near the center of rotation 201 of the cam driving unit 200. It can be referred to as the lower end (206b). It is formed at the end of the rotary support 146 of the temporary stack portion 140, the temporary stack portion 140 is raised when the protrusion 147 inserted into the second driving groove 206 is at the rising end 206a. , It is lowered when it is at the lower end 206b.

In this case, the lower end 206b may be formed closer to the rotation center 201 of the cam driving part 200 than the rising end 206a of the second driving groove 206. In other words, the second driving groove 206 may be formed in a spiral or spiral form gradually approaching toward the rotation center 201 from the outer circumferential surface side of the cam driving unit 200.

The reason why the second driving groove 206 has a non-uniform radius of curvature compared to the first driving groove 204 is that, unlike the shutter bracket 112, the temporary stack part 140 has to move up and down with a height difference. . If the second driving groove 206 is formed with the same radius of curvature as the outer circumferential surface of the cam driving unit 200, even when the cam driving unit 200 rotates, the temporary stack unit 140 does not vertically move, but almost horizontal movement. do.

On the other hand, the guide pin 203 protrudes from the outer circumferential surface of the cam driving part 200 toward the inner surface direction of the cam driving part 200. The guide pin 203 may move along the cam guide 230 mounted to the frame 111. As the guide pin 203 rotates by the rotation of the cam driver 200, a cover (not shown) connected to the cam guide 230 moves toward the media outlet 115 along the slot 111a formed in the frame 111. Can be.

In addition, a radial rib 205 may be formed on the inner surface of the cam driving unit 200 based on the rotation center 201.

FIG. 8 is a perspective view showing a part of the automatic teller machine having a cam driver according to FIGS. 7A to 7D, and FIGS. 9 and 10 are parts connected to the cam driver and the cam driver according to FIGS. 7A to 7D. 11 is an exploded perspective view of the present invention, and FIG. 11 is a perspective view illustrating a connection state of the cam driving unit and the cover according to FIGS. 7A to 7D.

8 to 10, the front partition 144 of the temporary stack unit 140 may include a damping module 160 capable of varying a paper medium collision distance entering the temporary stack unit 140. . The damping module 160 is a portion in which a paper medium which is conveyed by the medium transfer device 130 and enters the temporary stack unit 140 collides with each other. It is a part which allows the paper medium to be neatly stacked on the support 142 of the temporary stack part 140.

The damping module 160 may move on the front partition 144 and is connected to a drive shaft 168 driven by the cam driver 200 to adjust the collision distance according to the winding of the paper medium. Can move on For this reason, the damping module 160 may also be driven by the cam driver 200.

9 illustrates a coupling relationship between the protrusion 147 of the temporary stack unit 140 and the second driving groove 206 formed on the inner surface of the cam driving unit 200. In addition, a lever 163 for moving the damping module 160 is connected to the drive shaft 168, and the pin portion 163a formed at the end of the lever 163 is formed on the inner surface of the cam driving portion 200. The damping module 160 may move while being caught.

Referring to FIG. 10, the damping module 160 may include a damping rail 162 and a movable part 161 moving along the damping rail 162 formed on the support 142 or the front partition 144. The movable part 161 is moved along the damping rail 162 by the drive shaft 168.

Meanwhile, referring to FIGS. 10 and 11, a coupling relationship between the guide pin 203 of the cam driving unit 200 and the cam guide 230 is illustrated. The cam guide 230 has a pin rail 232 formed in the vertical direction. When the cam driving unit 200 rotates while the guide pin 203 is inserted into the pin rail 232 of the cam guide 230. The guide pin 203 may move along the pin rail 232 to its upper end, and then the cam guide 230 may move along the slot 111a (see FIG. 5) formed in the frame 111. In this case, a cover 167 covering the upper opening of the temporary stack part 140 is connected to one side of the cam guide 230. The cover 167 covers the upper opening of the temporary stack unit 140 when a paper medium is loaded in the temporary stack unit 140. That is, as the cam driving unit 200 rotates, the guide pin 203 moves along the pin rail 232 of the cam guide 230, and in this process, the cam guide 230 is a slot 111 a formed in the frame 111. The upper opening of the temporary stack unit 140 may be covered or opened while moving along).

Hereinafter, the operation of the cam driving unit 200 will be briefly described with reference to the drawings. Although not shown, the carriage transfer unit 170 may be driven by a belt or the like connected to the cam driving motor 250 for driving the cam driving unit 200.

5 and 6, the cam connecting portion 112a of the shutter bracket 112 is positioned at the end of the first driving groove 204 of the cam driving unit 200. In this state, when the cam driving unit 200 rotates counterclockwise, the cam connecting unit 112a is caught by the end of the first driving groove 204 and the shutter bracket 112 is moved to the opposite side of the medium outlet 115. As the shutter bracket 112 moves, the shutter 116 connected by the shutter slot 112b moves to the top of the shutter slot 112b, and the media outlet 115 may be opened while the shutter 116 is lifted.

Meanwhile, when the cam driving unit 200 rotates in the clockwise direction in the state shown in FIGS. 5 and 6, only the first driving groove 204 is rotated without the cam connecting unit 112a moving.
