Description

Media recovery method of media dispenser {Control method for media dispenser}

The present invention relates to a media dispenser, and more particularly, to a media recovery method of a media dispenser that prevents the release of unnecessary media during the power-up initialization process. It is a device capable of automatically supplying the medium, which is made of a standard and a certain thickness and can be made to pay a single sheet regularly.

1 shows a configuration of a media dispenser according to the prior art. As shown in the drawing, the media dispenser according to the prior art comprises a media cassette 10, a feed module 20, a thickness detection unit 30, a delivery module 40, and a recovery box 50.

The media cassette 10 is a place for storing the media for payment, and is provided with a media separation unit 12 for separating the media stored therein for delivery to the feed module 20 one by one. The medium separator 12 is driven by a DC motor 25 provided on the feed module 20 side.

The medium discharged from the medium cassette 10 is delivered to the medium detection unit 30 by the feed module 20. At this time, in the feed module 20, the medium is conveyed by the belt 20v and the roller 20r driven by the plurality of pulleys p.

In the thickness detection unit 30, the thickness is detected while the medium is transferred by the roller 30r. In the thickness detecting unit 30 as described above, two media are sensed to be transferred at once.

The medium passing through the thickness detection unit 30 is transferred from the delivery module 40. The delivery module 40 delivers the medium to the discharge unit 42 for delivering the medium from the customer, and recovers the medium transported at the same time with the bad medium and the two sheets to the recovery box 50 through a separate path. Will be transferred.

In other words, the delivery module 40 is divided into two delivery paths. One is a path for delivering the medium to the customer, and the other is a path for transferring the delivery box 50.

In such a delivery module 40, a medium is also conveyed by a plurality of pulleys 40p, a belt 40v, and a roller 40r. The feed module 20, the thickness detecting unit 30, and the driving motor 45 for driving each of the pulleys, the belt, and the rollers of the delivery module 40 are provided at one side of the delivery module 40. The power of the drive motor 45 is transmitted to the driven pulley 48 by the belt 47 wound on the drive pulley 46, and the pulley and the roller from the driven pulley 48 to the belt and gear, etc. Is passed using.

In the automatic media dispenser having such a configuration, the media contained in the media cassette 10 are separated one by one by the banknote separator 12 driven by the DC motor 25 and transferred to the feed module 20. Then, the feed through the feed module 20 detects that the two sheets at the same time in the thickness detection unit 30 is delivered to the delivery module 40. The delivery module 40 delivers the medium to the discharge unit 42 accessible to the customer. In addition, the defective medium or the medium in which the two sheets are delivered at the same time is recovered to the collecting box 50.

When the power supply is turned off in the process of transporting for discharging the media in the media dispenser having such a configuration, it is necessary to recover the media existing on the media discharge path so as not to be delivered to the customer. In particular, when power is cut off by a power failure or the like while the medium is being discharged at the request of the customer, it is necessary to first perform an operation for recovering the medium existing on the medium discharge path.

Therefore, the media dispenser first performs an initialization operation for recovering the media existing on the media discharge path immediately after the power is supplied again and before the media is discharged at the request of the customer.

However, in the conventional media dispenser, the media is delivered from the media cassette 10 to the discharge section 42 or recovered from the media cassette 10 to the discharge section 42 immediately after the power is supplied again. It was possible to recover only the media that existed between the branching points branched for delivery.

Therefore, in the delivery module 40, the media existing on the media transfer path between the discharge portion 42 from the branching point where the medium is transferred to the discharge portion 42 or the discharge box 50 is impossible to recover. Thus, there is a concern that the medium may be unnecessarily released.

Accordingly, it is an object of the present invention to provide a medium recovery method of a media dispenser capable of recovering a medium that is selectively present in the entire area of the medium transport path.

It is also an object of the present invention to provide a medium recovery method of a media dispenser capable of preventing the medium from being discharged unnecessarily at the time of power supply again.

It characterized in that the control so that.

In addition, the present invention further comprises the step of detecting the occurrence of the jam, when the jam occurs, to control the recovery of the media existing on the media transport path by the above processes prior to the service for the medium discharge It features.

And the present invention is characterized in that the forward movement is controlled first, and then the forward movement in controlling the medium transport distance.

Hereinafter, a medium recovery method of a media dispenser according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram of a media dispenser according to the present invention.

First, an optical sensor 170 for sensing a medium passing through the first feed roller 160 is provided. The optical sensor 170 detects that the medium is discharged from the media case 103 and transported to the position of the optical sensor 170. The pickup roller is connected to the pickup roller through the clutch 140 based on the detection signal. The power is transmitted back to 130, and the thickness detection unit 175 to be described below to prepare for the thickness detection. In addition, the signal sensed by the optical sensor 170 is used to control the operation of the diverter 180 to be described below.

A reject sensor 172 is provided at a position corresponding to the inlet of the recovery box 105. The reject sensor 172 detects a medium delivered to the collection box 105, detects a reject state, and generates a signal for turning off the diverter 180 after the rejection is completed. And serves to transmit power to the pickup roller 130 through the clutch 140 to transfer new media.

Next, the emission sensor 174 is provided in front of the release rollers 168 and 168 '. The emission sensor 174 not only detects the finally released medium but also senses the medium caught on the transport path in an emergency. The emission sensor 174 provides information for controlling the operation of the diverter 180 and the operation of the clutch 140 based on the detection signal.

On the other hand, the thickness detecting unit 175 for detecting the thickness of the medium passing through the optical sensor 170 is provided at a position passing through the optical sensor 170. The thickness detecting unit 170 actually detects the thickness of the medium by a mechanical configuration and detects that the two media are simultaneously transferred. Since the configuration of the thickness detecting unit 170 is general, further description thereof will be omitted.

Next, the diverter 180 is provided near the fourth feed roller 163. The diverter 180 is to separate and transfer the normally discharged medium to be transferred to the recovery box 105, and the first transfer belt 155 and the second transfer belt 156 It is located at the end of the connection. The diverter 180 is driven by the solenoid 182.

And the rotation wheel 185 is installed on the guide plate 101 coaxially with the fifth feed roller 167. The rotary wheel 185 is installed coaxially with the fifth feed roller 167 and is rotated by the rotation of the fifth feed roller 167. In addition, a rotation sensor 186 for detecting the rotation of the rotary wheel 185 is installed on the guide plate 101. The rotation sensor 186 detects the rotation of the rotation wheel 185 to detect the rotation state of the drive motor 110.

Hereinafter, the operation of the present invention having the configuration as described above will be described.

When the driving motor 110 is rotated, the first pulley 120 is rotated by the timing belt 112t while the driving pulley 112 installed on the rotating shaft 111 is rotated.

Therefore, the separation driving pulley 122 is installed coaxially with the first separation pulley 120 is rotated. When the separation drive pulley 122 is rotated, the timing belt 122t wound thereon is driven. The timing belt 122t is wound around the guide pulley 126, the lower connection pulley 128, and the release pulley 124 so that they rotate together.

By this configuration, power is transmitted to the clutch 140 connected by the lower connection pulley 128 and the connection gear 142. The clutch 140 selectively transmits power according to detection signals of the optical sensor 170, the reject sensor 172, and the emission sensor 174. Power is selectively transmitted to the pickup roller 130 through the clutch gear 143 through the clutch 140.

The power transmitted to the discharge pulley 124 is transmitted to the discharge roller 168 through a gear to drive the second transfer belt 156. The first conveyance belt 155 is driven by a first conveyance roller 160 installed coaxially with the lower connection pulley 128. Of course, the first conveying belt 155 is also driven by the second and third conveying rollers (161,162) are wound.

The following describes that the medium stored in the media case 103 of the main unit 100 is released. The media of the media case 103 are taken out one by one by the clockwise rotation of the pickup roller 130. The medium taken out by the pickup roller 130 is guided to the transfer guide 138 by passing between the transfer roller 134 and the separation roller 136. At this time, the feed roller 134 and the separation roller 136 is rotated in the same direction to separate the two sheets are overlapped and the medium is transferred. Here, the pick-up roller 130 is not rotated because the power transmission is blocked by the clutch 140 after removing a single medium from the media case 103.

In addition, the medium guided by the separation roller 136 and transported along the transport guide 138 is guided along the inclined guide surface 154 of the connection guide 150 to form the first and second transport belts ( 155 and 156 to be transported.

When the medium enters and feeds between the first and second transfer belts 155 and 156 and is detected by the optical sensor 170, power is picked up through the clutch 140 by the detection signal of the optical sensor 170. The pick-up roller 130 is rotated again to be delivered to the roller 130 to take out the next medium. On the other hand, when the medium is detected by the optical sensor 170, the thickness detector 175 enters the standby operation state.

The medium is continuously conveyed by the driving of the first and second conveyance belts 155 and 156 and the thickness is detected by the thickness detecting unit 175. The thickness detecting unit 175 detects the thickness of the medium to be conveyed and detects that the medium overlaps two sheets and conveys the defective medium.

Here, if it is detected that the conveyed medium is two or bad, the diverter 180 is operated by this detection signal. That is, the diverter 180 is guided to enter the recovery box 105 while the medium being transported is lifted up. The tip portion of the diverter 180 is positioned at the portion where the first and second conveyance belts 155 and 156 are in contact with each other and selectively guides the conveyed medium toward the discharge rollers 168 and 168 'or the collecting container 105. Done.

If the medium to be conveyed is normal, the diverter 180 is guided between the third guide roller 169 and the second conveyance belt 156 and finally the second conveyance belt 156 and the discharge roller ( 168 ') to the outside. As such, when the medium is released to the outside, it is sensed by the emission sensor 174.

On the other hand, if the conveyed medium is abnormal or a jam occurs during conveyance, the conveying box 105 is delivered to the collecting box 105. In this case, the diverter 180 is driven by the solenoid 182 so that its tip is moved upward. Will be lifted. Therefore, the medium passing through the first conveyance belt 155 and the second conveyance belt 156 is not delivered to the third guide roller 169 and is guided along the bottom surface of the diverter 180 to be recovered. (105). The medium recovered in the recovery box 105 is sensed by the reject sensor 172.

In the media dispenser of the present invention operated as described above, when a jam occurs or power is supplied again, it is necessary to recover the media existing on the media transfer path.

The following describes an operation for recovering a medium existing on the medium transport path when a jam occurs or when the power is cut off and then supplied again.

3 is a flowchart illustrating an operation for recovering a medium of a media dispenser according to the present invention.

When it is confirmed that a jam has occurred on the medium transfer path, the controller (not shown) suspends the service for discharging the medium at the request of the customer, and performs a process for collecting the medium. In addition, in the event of a power failure or artificially powered off and then resupplied, the process of the present invention for media recovery is first performed before the service is performed again (step 500).

If it is determined in step 500 that the jam is generated and the power is resupplyed, the controller controls the emission sensor 174, the reject sensor 172, and the optical sensor 170 in a current position where the medium transfer belt is not transferred. Detects the media through If the medium is detected from any sensor in the detecting operation, an operation for recovering to the collecting box is performed (step 510).

When the medium is detected through the emission sensor 174 in step 510, the medium exists on the medium transport path through which the emission sensor 174 can be detected. Therefore, at this time, by driving the drive motor 110 in reverse rotation, the control to transfer the medium transfer belt back. The conveying in the rearward direction of the medium conveying belt is performed to the position where the medium can be recovered by the collecting box 105 through the diverter 180.

In addition, when the medium is detected through the optical sensor 170 or the reject sensor 172 in step 510, the medium transport capable of detecting the optical sensor 170 or the reject sensor 172. This is the case when there is a medium on the path. Therefore, in this case, driving is performed according to the forward rotation of the driving motor 111 until the medium detected by the optical sensor 170 is recovered to the collecting box 105 through the diverter 180 along the medium transport path. In addition, the medium detected by the reject sensor 172 is controlled to be recovered to the collecting box 105 by the diverter 180 along the medium transport path. As described above, the recovery of the medium is performed by the diverter. In the case of passing through 180, the reverse rotation driving of the drive motor 110 is performed, and in the case of not passing through the diverter 180, the forward rotation driving of the driving motor 110 is performed. This is because the diverter 180 is located at a portion where the first and second transfer belts 155 and 156 are in contact with each other. That is, as shown in FIG. 4A during normal medium transfer, the medium transferred to the diverter 180 is guided between the third guide roller 169 and the second conveyance belt 156, and finally, the second medium. The discharge belt 156 and the discharge roller 168 'are discharged to the outside. Therefore, when the discharge sensor 174 detects a medium to be recovered, the medium to be recovered is transferred to the diverter 180. Since it is located at the passing point, it is performed in the opposite direction to the normal medium conveying path. In this case, when the driving motor 110 performs the reverse rotation, the second conveying belt 156 is moved in the reverse direction while the discharge roller is rotated. The medium near 168 and the second conveyance belt 156 is guided between the third guide roller 169 and the second conveyance belt 156 and is moved to the front of the diverter 180 again. In this case, the moving distance is a value which is set to a distance that can be reached from the emission sensor 74 to the front of the diverter 180. In this way, the medium moved to the front of the diverter 180 is moved along the bottom surface of the diverter 180 when the tip of the diverter 180 is lifted while the solenoid 182 is driven under the control of the controller. It is recovered by retrieval. The state at this time is shown in FIG. 4B. That is, the medium recovery due to the reverse rotation of the drive motor 110 is performed in the opposite direction to the medium movement path due to the forward rotation of the drive motor 110. In this case, the moving distance is made of a value proportional to the distance from the sensor from which the medium is detected to the diverter 180, and the value is based on a value preset in the controller to control the movement of each medium. The diverter 180 provides a path through which the medium can be discharged to the outside during normal control, and recovers the medium by lifting the tip portion by driving the solenoid 182 when an abnormality occurs. In addition, when the medium to be recovered is detected by the optical sensor 170, the medium to be recovered is located at a point before passing through the diverter 180. When the medium to be recovered by the optical sensor 170 is detected, the control unit reaches the diverter 180 from the position of the optical sensor 170. The forward rotation of the drive motor 110 is performed by a distance sufficient to the following. Then, the diverter 180 drives the solenoid 182 to guide the medium toward the recovery box 105. The operating state of the diverter 180 at this time is shown in Figure 4b. Therefore, the medium reaching the position of the diverter 180 is not moved to the third guide roller 169 side, the lower end of the diverter 180 The control unit in this case also controls the medium to be recovered to the front of the diverter 180 to be moved, and then collects it by the guide of the diverter 180. The media is being moved. Therefore, the controller may perform the position control to move the medium from the current position of the medium to the front of the diverter 180, regardless of the position of the sensor at which position the sensor is to be recovered. The recovery operation of the medium is performed. This control operation is the same in the following.

Next, a description will be given of the operation of detecting and recovering the medium when the medium is present via the emission sensor 174 or when the medium is present via the optical sensor 170.

The control unit (not shown) allows the medium transport belt to transfer the first predetermined distance backward in controlling the driving of the driving motor 111. The first predetermined distance is preferably about 10 mm, and the predetermined distance is preferably set according to the characteristics of the product.

That is, it becomes possible to detect the medium existing on the medium transport path within the first predetermined distance from the position of the emission sensor 174 and the optical sensor 170 to the discharge port side. In this case, when a signal according to the media detection is input to the controller from an arbitrary sensor, the controller determines the distance and position from the sensor on which the media has been detected to the diverter 180 and collects the detected media 105. The driving motor 110 is driven to be recovered (step 520).

The medium detection according to the transfer by the first predetermined distance is repeatedly performed any number of times (about 3 times). At this time, the repetition frequency is preferably adjusted according to the characteristics of the product.

By the above operation, the medium existing within the arbitrary distance via the emission sensor 174 and the medium existing within the arbitrary distance via the optical sensor 170 can be detected by each sensor. .

Next, in contrast to the operation of step 520, the medium transport belt is forwarded while detecting and recovering the medium existing in the medium transport path. As described above, in step 520, the medium conveyance belt is first conveyed backward, and then the forward conveyance in the next step 530 is performed in the diverter 180 or the discharge sensor 174 while the medium conveyance belt is conveyed forward. This is to prevent the existing medium from being discharged through the outlet.

That is, step 530 is a step in which the medium transport belt transfers the first predetermined transfer distance in the future, and in the process, a medium existing on the medium transfer path through each sensor is detected.

Accordingly, in step 530, it is possible to detect a medium existing between the diverter 180 and the emission sensor 174. That is, when the medium transport belt is forwarded by the first predetermined distance by the driving of the driving motor 110, the emission sensor 174 senses the medium existing on the medium transport path, and if detected, the diverter 180 Generates a control signal for driving. In the step 530, the forwarding operation of the medium transport belt is also repeated a predetermined number of times (about 7 times) by the first predetermined distance.

Therefore, the medium existing between the diverter 180 and the emission sensor 174 at the time when the power is re-supplied is moved by the emission sensor 174 in the process of being forwarded by the first predetermined distance in step 530. It becomes a detection and can collect | recover to the collection | recovery box 105 under control of a control part.

In operation 530, it is possible to detect a medium existing on the medium transport path that is short of the optical sensor 170. That is, the medium that was present between the media cassette 103 and the optical sensor 170 at the time when the power was re-supplied, the light in the process of transferring the medium conveying belt forward by the first predetermined distance in step 530 It becomes a detection by the sensor 170, and it becomes possible to collect | recover to the collection | recovery box 105 under control of a control part.

After the process for detecting the presence of the medium while transferring the first predetermined distance in steps 520 and 530 ends, the next step is to extend the conveying distance more than the first predetermined distance to convey the second predetermined distance. Perform a process to detect existence.

That is, in steps 540 and 550, the media transfer belt is controlled to be transferred by the second predetermined distance (about 50 mm) to detect the presence of the media on the media transfer path. Of course, it is preferable to also set the said 2nd predetermined distance to an appropriate value according to a product.

In step 540, when the medium is present on the diverter 180 or at a point slightly shorter than the medium, the optical sensor 170 detects the medium on the medium transport path.

That is, in step 540, the medium is transferred through the sensor by a predetermined number of times (about 5 times) by the second predetermined distance, and the detected medium is recovered. When the medium conveying belt is conveyed backward, the medium that was present on the diverter 180 or slightly below the diverter 180 is conveyed backward with the conveying belt and thus through the optical sensor 170. Is detected. When the medium is detected, the photosensor 170 transmits the operation control information of the diverter 180 for the recovery of the medium to the controller (not shown).

Therefore, through the operation of the step 540, it is possible to detect and recover the medium existing on the medium transfer path between the optical sensor 170 and the diverter 180.

In operation 550, the media transfer belt is transferred forward by a second predetermined distance, and the media is sensed through each sensor and the detected media is recovered. The operation in operation 550 is performed a predetermined number of times (about 7 times) than the operation of operation 540.

Therefore, the step 550 is to confirm and detect the medium existing between the light sensor 170 and the emission sensor 174 again.

That is, the present invention is capable of detecting a medium existing on the medium transport path corresponding to the position of each sensor in step 510, and in step 520 a predetermined position between the emission sensor and the discharge port and via the optical sensor. It is possible to detect the medium present in the. In operation 530, it is possible to detect a medium existing between the diverter and the emission sensor and at a point less than the optical sensor. In operation 540, it is possible to detect a medium existing on the diverter and between the optical sensor and the diverter. In operation 550, the operation of confirming the entire medium transfer path is performed once again, thereby preventing the release of unnecessary medium.

According to the present invention as described above, if the jam occurs or the power is re-supply during the performance of the service, before the service required by the customer to prevent the release of unnecessary media, the entire area of the media transport path It can be seen that the basic technical idea is to check whether the medium exists and to recover the medium if it exists.

And within the scope of the technical idea of the present invention, of course, various modifications are possible to those skilled in the art.

According to the present invention as described above, it will be appreciated that the following advantages can be provided.

First, the medium recovery method according to the present invention is capable of recovering a medium existing between the diverter and the discharge sensor as compared with the conventional method in which only the medium between the medium cassette and the diverter can be recovered. This means that the existing medium can be recovered over the entire area of the medium transport path existing in the network.

In addition, according to the present invention, it is possible to expect the advantage that it is possible to suppress the release of the medium more accurately, by performing the operation of repeatedly checking the medium that can exist substantially in any position of the medium transport path. .
