Description

Media collection method and media collection apparatus of a media dispenser {Method and Apparatus of Media collecting for Media Dispenser}

The present invention relates to a media dispenser, and more particularly, to a media retrieval method and a media retrieval apparatus of a media dispenser, which enables the customer to stably recover the media dispenser while collecting the unreceived media.

The media dispenser is provided with a clamp assembly that transfers the media requested by the customer to the customer service unit for the customer to pick up. The clamp assembly also provides a function to return the media to the media retrieval if the customer has not received the media. Hereinafter, the clamp assembly will be referred to as a medium recovery device.

In order to recover the medium, the medium recovering device moves upward of the medium collecting box, and then releases the clamped medium into the medium collecting box while the door of the medium collecting box is opened. In the medium recovery device, the clamping state is a state in which the clamp bracket rotates toward the clamp base side about the rotation axis to press the medium, and in the clamping release state, the clamp base and the clamp bracket are separated from the rotation axis by one end so that the medium is between them. Say no state.

In this case, the clamping and the clamping release operation in the medium recovery apparatus are performed by the sensor bracket and the sensor structure. These configurations are shown in FIG. 1 is a partial perspective view of a media recovery apparatus to which a sensor bracket according to the prior art is applied.

Referring to FIG. 1, the sensor bracket 1 is formed in a cylindrical shape connected to one end of the rotation shaft 3, and two sensor bars 1a and 1b are connected to each other on the outer circumferential surface thereof so as to recognize clamping and release of clamping. It is formed facing the other direction.

When the sensor bracket 1 rotates forward / reverse, a sensor unit 5 including two sensors 5a and 5b having grooves formed on the front surface thereof is installed to accommodate the sensor bars 1a and 1b, respectively.

In the above structure, the sensor bars 1a and 1b formed in the sensor bracket 1 are not simultaneously accommodated in the grooves of the two sensors 5a and 5b. That is, when one sensor bar 1a is accommodated in the corresponding sensor 5a groove, the other sensor bar 1b is outside the corresponding sensor groove 5b. Here, when the sensor bar 1a is in the groove of the sensor 5a, the medium is clamped. On the other hand, when the other sensor bar 1b is in the groove of the sensor 5b, the medium is unclamped. That is, the state of the media can be known by sensing the position of the sensor bars 1a and 1b.

Therefore, when the rotating shaft 3 is rotated in the open direction by the driving of the finger motor 7 while the medium is clamped, the clamp bracket 9 is spaced apart from the clamp base 10. Accordingly, the medium enters the medium recovery box located below. Accordingly, the medium recovery operation is performed.

The sensor bracket 1 rotates together with the rotation shaft 3 according to the driving of the finger motor 7 even during the medium recovery operation. Thus, when the sensor bar 1a of the sensor bracket 1 is separated from the corresponding sensor 5b and the other sensor bar 1b is located in the corresponding sensor 5b groove, the detection signal from the sensor 5b is detected. The control unit (not shown) receiving the recognition recognizes that all of the clamping release states are completed. The controller stops driving of the finger motor 7. At the same time, the door of the media collection box is closed.

However, the prior art has the following problems.

First, when unclamping a medium, the finger motor 7 continues to operate for a certain time. That is, the sensor bracket 1 continues to rotate until another sensor bar 1b is received in the sensor 5b groove and released while the sensor bar 1a is received and clamped in the sensor 5a groove. Doing.

At this time, the door of the media collection box should be opened when the sensor bar 1a is pulled out of the sensor 5b groove by the rotation of the sensor bracket 1. If the door is not opened, media recovery will not be performed normally.

Therefore, in the prior art, the door opening time of the finger motor 7 and the medium collection box must be accurately matched.

However, due to the assembling characteristics of the finger motor 7 and various components connected to the finger motor 7 and transmitting power to the sensor bracket 1, the finger motor 7 is carried out for each of the media recovery devices. Because of the different driving points of, it was cumbersome to get it right, and it took a lot of time.

In addition, when releasing the clamping of the medium in the medium recovery device, the clamp brackets 9a and 9b holding the medium should be spaced apart from the clamp base 10 at the same time and fall in a horizontal state. However, the clamp brackets 9a and 9b used to clamp the medium are formed in pairs, and the clamp brackets 9a and 9b are pressed in the direction of the clamp base 10 to provide elasticity. Two elastic members, namely torsion springs 11a and 11b, are also formed in pairs in accordance with the clamp brackets 9a and 9b. In this case, the torsion springs 11a and 11b may have deviations. For example, when the clamping and de-clamping operations are repeatedly performed, the elastic force that was initially provided changes, at which time the pair of torsion springs 11a and 11b do not change together at the same value.

Therefore, a difference occurs when one end of the clamp brackets 9a and 9b is spaced apart from the clamp base 10.

As a result, the clamp brackets 9a and 9b are driven at different times, respectively, so that the medium falls downward in an inclined state. In some cases, the media may be rotated 90 degrees rather than horizontal, and fall into a vertical state. Because of this, it is difficult to recover the medium normally.

Accordingly, an object of the present invention is to solve the above problems, and to provide a media recovery method and a media recovery apparatus of a media dispenser to enable the customer to stably recover the unreceived media from the media dispenser into the media collection box. will be.

According to a feature of the present invention for achieving the above object, it is provided on the clamp base of the media dispenser and formed with a groove on the front, respectively, consisting of a first sensor and a second sensor for detecting the clamping state and the clamping release state of the medium Sensor unit; A sensor bracket connected to one end of a rotation shaft installed on the clamp base, and having a plurality of sensor bars formed on an outer surface of the first and second sensors; If two sensor bars of the plurality of sensor bars are simultaneously accommodated in the grooves of the first sensor and the second sensor while the clamping release state is in progress due to the rotation of the sensor bracket, the driving finger motor is released to release the clamping of the medium. And a control unit which stops the operation of the door and opens the door so that the medium on the upper surface of the door of the media collection box is recovered into the media collection box.

The sensor bracket is formed on a cylindrical body and an outer surface of the body to be accommodated in only one of the grooves of the first sensor and the second sensor so as to sense a clamping state or a clamping release state of the medium. A sensor bar and a second sensor bar, and a third sensor bar and a fourth sensor bar that are simultaneously accommodated in the grooves of the first sensor and the second sensor when the clamping release operation stops driving of the finger motor for a predetermined time. .

One of the third sensor bar and the fourth sensor bar is formed to be first received in the groove of the first sensor or the second sensor when the sensor bracket rotates in the longitudinal direction of the body.

According to another feature of the invention, the control unit of the medium recovery device dropping the medium first to the upper surface of the door in the state that the door of the media collection box is closed; And opening the door to allow the control unit to recover the media dropped on the upper surface of the door into the media collection box.

According to another feature of the invention, the step of driving the finger motor installed on the clamp base of the medium recovery device dropping the clamped medium to the upper surface of the door of the media collection box; Simultaneously sensing the plurality of sensor bars formed on the sensor bracket by two sensors installed on the clamp base to sense clamping and clamping states of the medium while the finger motor is being driven; And when the sensor bar is detected, the control unit of the medium recovery device comprises the step of stopping the driving of the finger motor and opening the door to recover the media loaded on the upper surface of the door into the media collection box.

The sensing step is to detect whether the sensor bar is accommodated in the groove formed in the front of the sensor.

In the state in which the driving of the finger motor is stopped, the door is performed until fully opened.

The finger motor which is stopped driving is driven again when the door is completely opened.

In the present invention, a plurality of sensor bars are additionally formed on the sensor bracket for detecting the clamping and the clamping release state of the medium, thereby detecting the door opening time of the medium collecting box. That is, when the clamping of the medium is released by driving the finger motor, the medium first falls on the upper surface of the door of the medium collecting box. When two sensors simultaneously detect the corresponding sensor bar, the medium is opened by temporarily stopping the driving of the finger motor. It is to be recovered to the collection box. Accordingly, even when the medium falls in an inclined state when the clamping is released, the medium can be stably recovered into the inside of the medium collecting box.

In addition, in describing the embodiments of the present invention, when it is determined that a detailed description of a related well-known configuration or function interferes with the understanding of the embodiments of the present invention, the detailed description thereof will be omitted.

In addition, in describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are only for distinguishing the components from other components, and the nature, order or order of the components are not limited by the terms. If a component is described as being "connected", "coupled" or "connected" to another component, that component may be directly connected or connected to that other component, but between components It will be understood that may be "connected", "coupled" or "connected".

Next, a preferred embodiment of the present invention will be described.

Prior to the description, the configuration of FIG. 2 is different from that of FIG. 1 in which only the shape of the sensor bracket is described in the prior art, and other configurations are the same. In addition, it is noted that there is a difference in the method of recovering the media of the control unit performing the media recovery operation by the changed shape of the sensor bracket.

2 is a partial perspective view of a media recovery apparatus to which a changed sensor bracket is applied according to a preferred embodiment of the present invention, and FIG. 3 is a perspective view of the sensor bracket of FIG. 2.

First, referring to FIG. 2, the clamp base 100 is provided as a part on which the medium is seated. The clamp base 100 is provided with a pair of clamp brackets 103a and 103b.

The clamp brackets 103a and 103b are elastically supported by a pair of torsion springs 105a and 105b, respectively. The torsion springs 105a and 105b are provided on one rotation shaft 107 supported at both ends, and one end of the torsion springs 105a and 103b is pressed against the rotation shaft 107 to provide elastic force. . Accordingly, the clamp brackets 103a and 103b pressurize the media on the clamp base 100 to clamp the media.

The clamp brackets 103a and 103b are rotated by the finger motor 109 installed in the clamp base 100. A gear train for transmitting power is installed between the clamp brackets 103a and 103b and the finger motor 109. Thus, the clamp brackets 103a and 103b rotate forward or reversely according to the driving direction of the finger motor 109, that is, in a close or open direction, thereby clamping and clamping the medium. Make it.

One end of the rotating shaft 107 is installed with the sensor bracket 110 is extended. The sensor bracket 110 is shown in detail in FIG. 3.

Referring to FIG. 3, the sensor bracket 110 includes a body 112 formed in a cylindrical shape. Four first to fourth sensor bars 113, 114, and 1150 (116) protrude from the outer circumferential surface of the body 112 and are formed long, that is, two sensor bars (compared to the sensor bracket structure in the related art). 115 and 116 are further formed, and among the sensor bars 113, 114, and 1150 (116), the sensor bars 113 and 115 are formed on the same circumference and are spaced apart from each other. The 114 and 116 are formed to be spaced apart from each other on the same circumference in a state of being spaced apart from the sensor bars 113 and 115 in the longitudinal direction of the body 112. The separation distance is described later. The first sensor bar 113 and the second sensor bar 114 are formed so as to be spaced apart by an angle not simultaneously accommodated in the grooves of the first sensor and the second sensor. In addition, the third sensor bar 115 and the fourth sensor bar 116 may be accommodated in the groove of the first sensor and the second sensor almost simultaneously. So that the position of the four sensor bars 113, 114, 1150, 116 is not necessarily the same as shown in the drawing. If the first and second sensors corresponding to the sensor bars 113, 114, 115, and 116 are installed at different heights or spaced apart from each other, the sensor bars 113, 114, and 1150 ( This is because the formation position of 116 must also be different.

Referring to FIG. 2 again, a sensor unit 120 is provided on the clamp base 100 adjacent to the sensor bracket 110. The sensor unit 120 includes a first sensor 120a and a second sensor 120b each having a groove formed on the front surface facing the sensor bracket 110.

The distance between the sensor bracket 110 and the sensor unit 120 is such that the first to fourth sensor bars 113, 114, 115, and 116 are rotated by the first sensor when the sensor bracket 110 rotates. It is sufficient that the distance accommodated in the groove of the 120a) and the second sensor 120b to output the detection signal.

On the other hand, the relationship between the sensor bracket 110 and the sensor unit 120 is as follows.

First, when the first sensor bar 113 is accommodated in the groove of the first sensor 120a, the medium is clamped. On the other hand, when the second sensor bar 114 is accommodated in the groove of the second sensor 120b, the clamping of the medium is released. In this case, when the first sensor bar 113 is accommodated in the groove of the first sensor 120a, the second sensor bar 114 is not accommodated in the groove of the second sensor 120b. When the 114 is accommodated in the groove of the second sensor 120b, the first sensor bar 113 is not accommodated in the groove of the first sensor 120a.

In addition, the third sensor bar 115 and the fourth sensor bar 116 are simultaneously accommodated in the grooves of the first sensor 120a and the second sensor 120b. This is a time when the driving of the finger motor 109 is stopped for a predetermined time while the clamping is released while the medium is clamped, and a time when the door of the medium recovery device is opened.

On the other hand, although not shown in the figure, a media collection box for collecting the media is configured. The medium recovery box is located below the medium recovery device. The media collection box is provided with a door for opening and closing the inside of the media collection box. The door is opened and closed by a door driving motor.

In addition, a control unit for controlling the overall operation of the medium recovery device is provided. The controller receives the clamping and the clamping release state from the sensor unit 120 to determine the current state, and in particular, the third sensor bar 115 and the fourth sensor bar 116 during the clamping of the medium. When the first sensor 120a and the second sensor 120b are simultaneously accommodated in the grooves of the first sensor 120a and the second sensor 120b, the driving of the finger motor 109 is stopped and the door of the medium collection box is controlled to be opened.

The controller may be mounted at reference numeral 130. 130 is a printed circuit board on which the sensor unit 120 is mounted. The printed circuit board may be configured with various elements for processing sensor signals.

A method of recovering media in the media recovery apparatus of the present invention configured as described above will be described with reference to FIGS. 4 and 5. 4 is a driving state diagram of the sensor bracket of FIG. 3, and FIG. 5 is a flowchart illustrating a medium recovery method according to an exemplary embodiment of the present invention.

It is the case that the media is paid according to the customer's media payment order, but the media is in the customer service department because the media was not received.

Then, the media in the customer service part should be recovered by the media collection box (s100). Usually, the media recovery device is installed on the transfer tray of the media dispenser, and can be transported.

To do this, command to clamp the medium. Accordingly, the clamp brackets 103a and 103b rotate in the direction of the clamp base 100 to clamp the medium (s102). This clamping operation is possible because the clamp brackets 103a and 103b are also driven when the rotation shaft 107 is rotated by the driving of the finger motor 109.

When the clamping operation of the medium is completed, the first sensor bar 113 of the sensor bracket 110 is positioned in the groove of the first sensor 120a (s104). This state is shown in FIG. 4A. Thus, the controller recognizes that the clamping of the medium is completed.

As such, when the clamping operation of the media is completed, the media collection device is moved to the media collection box at the customer service unit. Specifically, to be located above the medium recovery box (s106).

When the medium recovery device is positioned correctly above the medium collection box, the controller drives the finger motor 109 in the open direction to release the clamping of the medium. The driving direction is opposite to the direction at the time of clamping.

Then, the rotating shaft 107 is driven and the clamp brackets 103a and 103b are spaced apart from the clamp base 100 to release the clamping of the medium (s108). The clamping release point is a point at which the first sensor bar 113 is separated from the groove of the first sensor 120a. In this case, the clamp brackets 103a and 103b are slightly opened from the clamp base 100. In other words, this operation is to provide a guide to the medium to be safely loaded on the upper surface of the door.

By such an operation, the medium falls on the upper surface of the door of the medium collecting box (S110). In this case, since the door of the medium recovery box is in an unopened state, the medium is loaded onto the upper surface of the door of the medium recovery box.

Since the finger motor 109 continues to be driven while the medium is falling, the rotating shaft 107 continues to rotate, and thus the clamp brackets 103a and 103b also open.

Thereafter, as shown in FIG. 4B, it is determined whether the third sensor bar 115 and the fourth sensor bar 116 are accommodated together in the grooves of the first sensor 120a and the second sensor 120b (S112). . As a result of determination, when the third sensor bar 115 and the fourth sensor bar 116 are accommodated together in the grooves of the first sensor 120a and the second sensor 120b, the controller controls the driving of the finger motor 109. Stop and start to open the door located above the media collection box (s114).

When the door is started to be opened, the medium separated on the upper surface of the door is dropped into the inside of the medium collecting box (S116). Even when the recovery operation of the medium is performed, the opening operation of the door continues. This is because the media may not be recovered by the media recovery due to the door that is not fully opened when there are a lot of media to be recovered.

As such, when the door is completely opened and the medium is all recovered in the medium collecting box, the control unit drives the finger motor 109 again (S118). That is, the sensor bracket 110 is continuously driven in the open direction so that one end of the clamp brackets 103a and 103b is completely opened from the clamp base 100. In this case, the time from when the finger motor 109 is stopped and driven again is from the time when the door starts to open until the time when the door is completely opened and the medium recovery is completed, and this time is set in advance. .

When the finger motor 109 continues to be driven and the time when the second sensor bar 114 is accommodated in the groove of the second sensor 120b arrives as shown in FIG. 4C (s120), the controller releases the clamping operation. Recognize that this is all done. Then, the driving of the finger motor 109 is stopped (s124). In this case, one end of the clamp brackets 103a and 103b is completely opened in the clamp base 100. If the second sensor bar 114 is not received because it is not accommodated in the groove of the second sensor 120b, the finger motor 109 continues to drive (s122).

When the recovery operation of the media is completed by such an operation, the control unit closes the door again, and the media recovery apparatus returns to the position where the media can be transferred to the customer service unit according to the customer's request for payment of the media.

As described above, in recovering the medium by releasing the clamping state in the state where the medium is clamped, if a predetermined time elapses from the time when the medium starts to drop, the driving of the finger motor is suspended, and the door of the closed medium collecting box is opened. Allow the medium to stably free fall into the interior of the media collection box. In addition, the driving stop of the finger motor and the door opening time can be easily recognized by changing the shape of the sensor bracket connected to the rotating shaft.

By doing so, the finger motor is driven for a predetermined time and the medium is released by clamping and the door is opened and collected inside the medium collection box while falling on the upper surface of the door, so that the driving time of the finger motor needs to be adjusted manually. There is no.

Moreover, even if the elastic force of the pair of torsion springs elastically supporting the pair of clamp brackets is different from each other and falls from one direction of the media, it first falls on the upper surface of the door, and then freely falls into the inside of the media collection box with the door open. Can be prevented from falling in an inclined state.

In the present exemplary embodiment, the third sensor bar 115 and the fourth sensor bar 116 may have heights different from each other in the longitudinal direction of the body 112. That is, when the sensor bracket 110 is rotated while the first sensor bar 113 is accommodated in the groove of the first sensor 120a, the third sensor bar 115 is first received in the corresponding first sensor 120a groove. And the fourth sensor bar 116 is later received in the groove of the second sensor 120b. Since the present invention is for releasing the clamped state of the medium, when the fourth sensor bar 116 is first accommodated in the corresponding second sensor 120b groove, all the clamped states are released. Because it can be misunderstood.

On the other hand, in the present embodiment, the shape of the sensor bracket is changed so that four sensor bars are formed so that the medium falls safely into the inside of the medium collecting box, but it is possible without changing the shape of the sensor bracket. That is, in the state in which two sensor bars are formed on the sensor bracket as in the related art, after sensing the clamping release sensor bar and completely unclamping the clamped medium, the inside of the medium container is safely stored even if the door of the medium container is opened. You can also drop it. This case can also be applied to the present invention.
