By the way, a paper leaf processing device for inspecting many paper leaves at high speed is known. Compared to ATMs, this type of paper leaf processing device is large enough to have a size of several meters in the length direction, and the transport path for transporting paper leaves is also long. For this reason, even if it can be visually recognized that the paper leaves are defective (deficient) at two locations provided on the transport path, for example, near the paper leaf input port and at the other one location, the two locations. Due to the long transport path between the sites, it takes a lot of time to search for paper leaf defects.

When the paper leaf processing device detects that a paper leaf defect has occurred, the operation of the device is stopped in order to prevent the defective portion from affecting the inspection of other paper sheets. If the operation is stopped in this way, the paper leaf processing apparatus cannot inspect the paper leaves. For this reason, if it takes a long time to search for a defective part, the work of inspecting paper leaves may be delayed, which may hinder the work.

The problem to be solved by the present invention is a paper leaf processing that can easily identify where on the transport path a defect has occurred when a large number of paper leaves are inspected at high speed. It is an object of the present invention to provide an apparatus and a paper leaf processing system.

The paper leaf processing apparatus according to one embodiment is provided at a different position between the transport path for transporting the paper sheets and the transport path, and has an identification number and an image of the paper leaves passing through the transport path.

Inspect the paper leaves by the inspection unit 112. The inspection unit 112 determines the ticket type of the paper leaf, and also detects the positive loss and the authenticity of the paper leaf. Generally, when inspecting the paper leaves contained in the paper leaf bundle after the paper leaves are manufactured (after printing), the paper leaves are stacked in the order of serial numbers. In the present embodiment, in order to inspect the paper leaves in such a case, the plurality of paper leaf bundles loaded in the input port 101 are in the order of serial numbers in the order of stacking.

Paper leaves determined to be genuine tickets by the inspection unit 112 are sent to the corresponding sealing units 113A to 113D for each ticket type, and are sealed by the sealing unit every predetermined number (for example, 100 sheets). Will be done. The sealed bundle of paper leaves is conveyed by the conveying belt 114 and sent to the outside.

The inspection unit 112 includes the input port sensor unit 112A, the first sensor unit 112B, and the sensor unit 112G. The input port sensor unit 112A includes, for example, an area camera, and is provided on the most upstream side of the transport path 111, that is, on the device internal side of the input port 101. The slot sensor unit 112A photographs the paper leaves taken in from the slot 101, and reads the serial number (identification information) uniquely assigned to the paper leaves together with the image of the paper leaves from the captured image. The serial number is composed of, for example, a combination of alphabets and numbers.

The first sensor unit 112B to the sixth sensor unit 112G are sensor units arranged at different positions of the transport path 111, and are arranged from the upstream side of the transport path 111 in the order of the first sensor unit 112B to the sixth sensor unit 112G. To. The first sensor unit 112B to the sixth sensor unit 112G are sensors for determining the ticket type and positive loss of paper sheets, respectively, and include, for example, an optical sensor, a magnetic sensor, an area camera, and a line sensor. In the present embodiment, the first sensor unit 112B to the sixth sensor unit 112G are configured to not only detect optical characteristics, magnetic characteristics, etc., but also detect images of paper sheets transported along the transport path 111. Will be done. The overall camera 115 is attached to the inside of the door constituting the housing of the paper leaf processing device 100, for example, and photographs the inside side of the paper leaf processing device 100. More specifically, the overall camera 115 captures the entire transport path 111 from the side.

FIG. 2 is a block diagram showing an example of the configuration of the paper leaf processing apparatus 100.
As shown in FIG. 2, the paper leaf processing device 100 includes a CPU (control unit) 10, a storage unit 20, an interface 30, an input unit 40, a display unit 50, a transport unit 70, an inspection unit 112, and an overall camera 115. Including.

The CPU 10 is a control device that controls the entire paper sheet processing device 100 including the transport unit 70 and the inspection unit 112. The storage unit 20 includes a non-volatile memory and a volatile memory, and stores various programs and various data for executing an inspection on paper sheets. The interface 30 is, for example, an interface for communicably connecting to an external computer (information processing device). The input unit 40 is a device for the user to input instructions to the paper leaf processing device 100. The display unit 50 is a device that displays predetermined information to the user.

The transport unit 70 transports a plurality of paper sheets loaded into the loading port 101 one by one to the inspection unit 112, and collects the paper leaves that have passed through the inspection unit 112 in any of the sealing units 113A to 113D. Perform transport control. As described above, the inspection unit 112 includes the input port sensor unit 112A to the sensor unit 112G, and inspects the quality of paper sheets such as print quality. The inspection unit 112 uses the inspection results obtained from the input port sensor unit 112A to the sixth sensor unit 112G to inspect the paper sheets according to a plurality of inspection items. Here, the inspection items of the paper leaves are, for example, each RGB color, the hue of the pattern, the position of the pattern, the accuracy of the serial number, the size, etc., and in the present embodiment, when performing these inspections, the paper is used. Images of leaves will be acquired. In the present embodiment, the case of acquiring an image of paper sheets will be described, but it is sufficient that at least the shape of the paper sheets can be acquired from each of the input port sensor unit 112A to the sixth sensor unit 112G.

The overall camera 115 is a camera having a wide-angle lens having a wide angle of view, and as described above, the entire transport path 111 is photographed from the side surface. Therefore, the overall camera 115 can photograph the state of the paper sheets being sequentially transported along the transport path 111 at high speed.

FIG. 3 is a diagram showing an example of the image storage unit 60.
The image storage unit 60 includes a sensor image storage unit 61 and an overall image storage unit 62. The sensor image storage unit 61 stores images of paper sheets obtained by the sixth sensor unit 112G from the input port sensor unit 112A in association with the serial number of the paper sheets. The whole image storage unit 62 stores the image taken by the whole camera 115. In the present embodiment, the image storage unit 60 is provided in the storage unit 20, but the present invention is not limited to this. For example, when the paper leaf processing device 100 is connected to an information processing device such as a computer via the interface 30, the image storage unit 60 may be provided in the storage unit in the computer.

FIG. 4 is a diagram showing an example of paper leaf P.
As shown in FIG. 4, the paper leaf P is a rectangular paper, and the serial number P1 for identifying the paper leaf P from other paper leaves is printed and the pattern P2 is printed. ing. The inspection unit 112 inspects whether or not the design of the paper leaf P, the print quality of the serial number, and the like satisfy a predetermined standard.

Next, the process of acquiring the image of the paper leaf P will be described. FIG. 5 is a flowchart showing an example of a process of acquiring an image of paper sheets P. This process is realized by the CPU 10 executing a program stored in the storage unit 20.

When the CPU 10 receives an instruction to start the inspection from the operator via the input unit 40, the CPU 10 takes in the paper leaves one by one from the bundle of paper leaves to be put into the insertion port 101, and the taken-in paper leaves. P is transported to any of the sealing portions 113A to 113D via the transport path 111. At this time, as shown in FIG. 5, first, the CPU 10 acquires an image of the paper leaves P captured from the slot 101 (ST101). That is, the CPU 10 photographs the paper sheets P from the upper surface (or the upper surface and the lower surface) by the input port sensor unit 112A, and acquires the photographed image. Next, the CPU 10 acquires the serial number of the paper leaf P based on the acquired captured image (ST102). Then, the CPU 10 stores the image of the paper sheets P in the sensor image storage unit 61 in association with the serial number acquired in this way (ST103).

Next, the images of the paper sheets P are acquired from the acquired images of the first sensor unit 112B to the sixth sensor unit 112G (ST104 to ST109). At this time, each of the images of the paper sheets P acquired by the first sensor unit 112B to the sixth sensor unit 112G is stored in the sensor image storage unit 61 in association with the serial number acquired by the process of step ST101. .. As a result, with respect to the paper leaves P taken into the paper leaf processing apparatus 100, the image of the paper leaves P acquired by the slot sensor unit 112A for each serial number assigned to the paper leaves P (at the time of taking in). The image) and the images of the paper sheets P acquired from the first sensor unit 112B to the sixth sensor unit 112G are stored in the sensor image storage unit 61. The sensor image storage unit 61 may also include images and inspection results related to other inspections in association with the serial number.

Next, a process of capturing the entire transport path 111 with the overall camera 115 and acquiring the captured image will be described. FIG. 6 is a flowchart showing an example of a process of acquiring an image of the entire transport path 111. This process is realized by the CPU 10 executing a program stored in the storage unit 20.

First, the CPU 10 determines whether or not the inspection has started (ST201). For example, as in the case of step ST101 of FIG. 5, this determination is made based on whether or not the instruction to start the inspection is received from the operator via the input unit 40. When it is determined that the inspection has started (ST201: YES), the CPU 10 starts image acquisition of the entire camera 115 (ST202). That is, the whole camera 115 is activated, the entire transport path 111 is photographed, and the process of storing the photographed image in the entire image storage unit 62 is started.

Next, the CPU 10 determines whether or not the inspection is completed (ST203). When the CPU 10 determines that the inspection has not been completed (ST203: NO), the process returns to step ST202 and continues the above-described process. That is, the process of acquiring the captured image of the entire camera 115 is continued. On the other hand, when it is determined that the inspection is completed (ST203: YES), the CPU 10 ends the image acquisition of the entire camera 115 (ST206), and ends this process. As a result, it is possible to acquire an entire image of the transport path 111 while performing the inspection of the paper leaf P.

Next, a process for detecting when the paper leaf P is damaged or broken, in other words, when an abnormality in the shape of the paper leaf P occurs will be described. FIG. 7 is a flowchart showing an example of processing for detecting an abnormality in the shape of the paper leaf P. This process is realized by the CPU 10 executing a program stored in the storage unit 20. In the present embodiment, this process is started after the paper leaves P after being taken in from the input port 101 are taken in and the paper leaves P pass through at least the sixth sensor unit 112G. ..

The CPU 10 specifies a serial number and acquires an image of the shape of the paper leaf P (ST301). As a result, the designated serial number and the image of the shape of the paper sheets P associated with the serial number are acquired from the sensor image storage unit 61. The serial numbers are designated in the order obtained from the paper sheets P by the process of step ST102 described above.

Next, the CPU 10 compares the acquired images (ST302). More specifically, the CPU 10 has an image of the paper sheets P acquired from the input port sensor unit 112A (first image) and a paper sheet P acquired from the first sensor unit 112B to the sixth sensor unit 112G, respectively. Compare each with the image (second image). The comparison is made based on the image of the paper leaf P acquired from the input port sensor unit 112A because the image of the paper leaf P when taken into the paper leaf processing device 100 is the original shape of the paper leaf P. is there.

Next, the CPU 10 determines whether or not there is an image having a predetermined defect rate or more (ST303). In the present embodiment, the CPU 10 calculates the defect rate of the shape obtained from the second image with respect to the shape obtained from the first image to be compared in the process of step ST302, and the defect rate is equal to or higher than the predetermined defect rate. In that case, it is determined that there is an abnormality. When the CPU 10 determines that there is no image having a predetermined loss rate or more (ST303: NO), the process returns to step ST301, and the same process is executed for the paper sheet P having the next serial number.

On the other hand, when it is determined that there is an image having a predetermined defect rate or more (ST303: YES), the CPU 10 displays an error (ST304). That is, the display unit 50 displays that the paper leaf P having an abnormal shape has been detected. The display of the display unit 50 at this time includes the fact that the abnormality has been detected, the image of the paper sheet P in which the abnormality has been detected, the sensor unit in which the abnormality has been detected, and the serial number. Then, the CPU 10 stops the uptake of the paper sheets P (ST305). As a result, the paper leaf processing apparatus 100 does not take in new paper leaves P from the input port 101.

Next, the CPU 10 determines whether or not the processing of the captured paper sheets P is completed (ST306). For example, the CPU 10 determines based on whether or not all the serial numbers stored in the sensor image storage unit 61 have been processed. If it is determined that the CPU 10 has not finished (ST306: NO), the process returns to step ST301, and the same process is executed for the paper sheets having the next serial number. On the other hand, if it is determined that the process has ended (ST306: YES), the CPU 10 ends this process. As a result, a process of comparing images with all the captured paper sheets P is executed. If an abnormality is detected again after the abnormality is detected once, an error display (ST304) is displayed, but since the uptake of new paper sheets P has already stopped, the process of step ST305 is performed. Instead, the process of step ST306 is executed.

FIG. 8 is a diagram showing an example of an error display displayed on the display unit 50.
As shown in FIG. 8, the display screen example 50A shows that an abnormality of the paper leaf P was detected (an error was detected in the paper leaf), and an image of the paper leaf P in which the abnormality was detected (paper leaf). The image in which the upper left of the class P is missing), the sensor unit that detected the abnormality (the detection sensors are the 5th sensor and the 6th sensor), and the serial number of the paper sheet P that detected the abnormality are displayed. In the illustration, only one image of the paper leaves P corresponding to the acquired image of the fifth sensor unit 112F is shown, but the paper leaves P corresponding to the acquired image of the sixth sensor unit 112G by a predetermined operation. Image can be displayed. Further, the images corresponding to the 5th sensor unit 112F and the 6th sensor unit 112G may be displayed at the same time.

Next, a process of displaying an image relating to the paper leaf P in which the abnormality is detected will be described. FIG. 9 is a flowchart showing an example of a process of displaying an image of paper sheets in which an abnormality is detected. This process is realized by the CPU 10 executing a program stored in the storage unit 20.

As shown in FIG. 9, the CPU 10 determines whether or not the input of the serial number has been accepted (ST401). For example, the CPU 10 may make this determination based on whether or not the serial number has been input by the operator from a predetermined screen, and when the serial number on the display screen of FIG. 8 is linked, the CPU 10 may make this determination. This determination may be made based on whether or not the serial number has been clicked.

When it is determined that the input of the serial number is accepted (ST401: YES), the CPU 10 acquires the image associated with the serial number (ST402). More specifically, the CPU 10 acquires images of the paper sheets P acquired from the input port sensor unit 112A associated with the serial number that received the input, and the sixth sensor unit 112G from the first sensor unit 112B.

When the image is acquired in this way, the CPU 10 displays the image on the display unit 50 (ST403). As a result, each image is displayed on the display unit 50 in a predetermined format. Then, this process ends.

FIG. 10 is a diagram showing a screen display example 50B displayed in step ST403.
As shown in FIG. 10, on the upper side of the screen display example 50B, it is displayed that each image has a predetermined serial number. Further, the image of the paper sheets P acquired from the slot sensor unit 112A is displayed as the captured image D1 together with the characters (corresponding information) of the captured image. Further, the first sensor images D2 to the sixth sensor images D7 of the paper sheets P acquired from the first sensor unit 112B to the sixth sensor unit 112G are the characters (corresponding information) of the first sensor image to the sixth sensor image, respectively. Is displayed with. The captured image D1 is displayed at the upper part, and the first sensor image D2 to the third sensor image D4 and the fifth sensor image D5 to the sixth sensor image D7 are displayed in two stages below the captured image D1. In this way, the captured images D1 and the first sensor images D2 to the sixth sensor images D7 of the paper sheets displayed on the display unit 50 correspond to the positions provided in the transport path 111 of the sensor unit for acquiring the images. It is displayed side by side. The arrangement method of the images D1 to D7 can be arbitrarily set. In the example shown in FIG. 10, not only the shape of the paper leaf P but also the design is displayed, but at least the shape may be displayed.

As shown in FIG. 10, in the screen display example 50B, the upper left of the fifth sensor image D6 and the sixth sensor image D7 is missing, and a state in which an abnormality has occurred is displayed. On the other hand, the defect is not found in the captured image D1 and the first sensor image D2 to the fourth sensor image D5. As shown in FIG. 1 described above, the order of the sensor units is as follows: from the upstream side of the transport path 111, the input port sensor 112A, the first sensor unit 112B, the second sensor unit 112C, the third sensor unit 112D, and the fourth sensor. Since it is the unit 112E, the fifth sensor unit 112F, and the sixth sensor unit 112G, the operator confirms the screen display example 50B, and the operator can see the paper leaf between the fourth sensor unit 112E and the fifth sensor unit 112F. It can be predicted that a defect has occurred in class P.

When the paper leaf processing apparatus 100 detects an abnormality in the paper leaf P, the paper leaf processing device 100 does not take in the paper leaf P after that, so that the operator confirms the screen display example 50B shown in FIG. 10 and the operation is completed. Occasionally, the operation is stopped. Therefore, after confirming the screen display example 50B, the operator first takes out the paper sheets P in which the abnormality is detected from the sealing portions 113A to 113D. In the present embodiment, since the paper sheets P are transported in the order of serial numbers, which sealing part is located if the serial number can be grasped, and which position of the stacked paper sheets P is located. Can be easily grasped. The operator confirms the removed paper leaf P, and confirms whether the upper left of the paper leaf P is broken or damaged.

When it is confirmed that the paper leaf P is not broken, that is, it is damaged, the operator immediately opens the housing of the paper leaf processing device 100, and the fourth sensor unit 112E of the transport path 111 and the fourth sensor unit 112E Check the distance between the sensor and the fifth sensor unit 112F. As a result, the operator can detect the defect of the paper leaf P in the shortest time.

Further, since the paper sheets P are conveyed at high speed in the transport path 111, the defective portion of the paper leaves P is separated from the fourth sensor unit 112E and the fifth sensor unit 112F of the transport path 111 due to the momentum. It is also possible to fly to the place of. In this case, no missing portion is found even if the fourth sensor unit 112E and the fifth sensor unit 112F of the transport path 111 are checked. In such a case, in the present embodiment, the image taken by the whole camera 115 stored in the whole camera image storage unit 62 is confirmed. As described above, when the defective portion flies, the state can be confirmed from the camera image. Therefore, the operator can grasp the flying direction of the defect by confirming the camera image. it can. Then, the operator can easily find the defective portion by searching for a place in the direction ahead.

In the above embodiment, an error display (reference: FIG. 8) and an image display of the paper leaf P in which an abnormality is detected (reference: FIG. 10) are displayed on the display unit 50 of the paper leaf processing apparatus 100. However, it is not limited to this. For example, as described above, when the information processing device such as a computer is connected via the interface 30 and the image storage unit 60 is provided in the storage unit in the computer, an error occurs in the display unit of the information processing device. The display and the image of the paper leaf P in which the abnormality is detected may be displayed.

(Second Embodiment)
In the second embodiment, a device for cutting the paper leaf P determined to be a loss ticket by the inspection unit 112 is added to the paper leaf processing device 100, and the process of cutting the loss ticket is performed using this device. The difference from the first embodiment is that a process of determining whether or not the paper sheets P that are executed and determined to be a loss ticket and the cut paper sheets P match or not is added. The same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 11 is a diagram showing an example of a schematic configuration inside the paper leaf processing apparatus 100 of the present embodiment. The paper leaf processing apparatus 100 of the present embodiment is provided with a branch transport path 111a that branches from the transport path 111, and the branch transport path 111a extends to the cutting section 117. Further, a sensor unit 118 for photographing the paper sheets P transported to the cutting unit 117 is provided. In the present embodiment, the inspection of the paper leaves P is not performed immediately after being manufactured (printed), but is performed on the bundle of the paper leaves P collected after being distributed. This is the case.

The branch transport path 111a is a transport path for transporting the paper sheets P determined to be a loss ticket by the inspection unit 112 to the cutting unit 117. Here, the non-performing ticket is a paper leaf P in which the degree of dirt attached is large and it is desirable not to distribute it again. The cutting unit 117 is a device for cutting the paper sheets P determined to be a loss ticket. The sensor unit (pre-cutting sensor unit) 118 is, for example, an area camera, and photographs paper sheets P before being cut by the cutting unit 117.

FIG. 12 is a block diagram showing an example of the configuration of the paper leaf processing apparatus 100.
As shown in FIG. 12, the paper leaf processing apparatus 100 of the present embodiment has a cutting unit 117 and a sensor unit 118 added. The paper leaf P to be cut by the cutting unit 117 is photographed by the sensor unit 118, the serial number is recognized from the photographed image, and the photographed image is stored in association with the serial number. For example, it is stored in a predetermined first area in the image storage unit 60 described above. On the other hand, the paper sheets P determined to be a loss ticket by the inspection unit 112 are also stored in a predetermined second area in the image storage unit 60 in association with the serial number.

Next, a process of cutting the loss ticket and determining whether or not the paper leaf P determined to be a loss ticket and the cut paper leaf P match or not will be described. FIG. 13 is a flowchart showing an example of a process of determining whether or not the paper sheets P determined to be a loss ticket and the cut paper sheets P match. This process is realized by the CPU 10 executing a program stored in the storage unit 20.

As shown in FIG. 13, the CPU 10 determines whether or not an operation for confirming the cut paper sheets P has been accepted (ST501). For example, the determination is made based on whether or not the operator has operated the input unit 40 on the predetermined screen display displayed on the display unit 50 to confirm the cut paper sheets P.

When it is determined that the operation has been accepted (ST501: YES), the CPU 10 acquires the serial number of the paper leaf P determined to be a loss ticket and its image (ST502). In the present embodiment, the CPU 10 acquires the serial number and the image of the paper leaf P determined to be a loss ticket stored in the second area of the image storage unit 60. Next, the CPU 10 acquires the serial number of the paper sheets P before cutting and the image thereof (ST503). In the present embodiment, the CPU 10 acquires the serial number and the image of the uncut paper sheets P stored in the first area of the image storage unit 60.

Next, the CPU 10 determines whether or not they match (ST504). More specifically, the CPU 10 matches the serial number of the paper leaf P obtained in the process of step ST502 as a loss ticket and the serial number of the paper leaf P obtained in the process of step ST503 before cutting. Judge whether or not.

If it is determined that they match (ST504: YES), the CPU 10 displays on the display unit 50 that they match (ST505). On the other hand, when it is determined that they do not match (ST504: NO), the CPU 10 displays on the display unit 50 that they do not match, and at least displays the serial numbers of the non-matching paper sheets P and their images. Display (ST506). In general, the paper leaf P determined to be a loss ticket and the paper leaf P to be cut are in principle the same. However, it is conceivable that some kind of situation may occur and paper sheets P that have not been cut even though the ticket has been determined to be a loss ticket may occur. In the present embodiment, in such a case, the serial number of the paper sheets P whose serial numbers do not match and the image thereof are displayed on the display unit 50.

According to the paper leaf processing apparatus 100 described above, the operator can confirm whether or not the paper leaf P determined to be a loss ticket has been reliably cut by the cutting unit 117. Therefore, if the paper leaf P determined to be a loss ticket is not cut and is lost, the operator can grasp that the paper leaf P has been lost.

In the first embodiment, the case where the captured image of the entire camera 115 is acquired from the start to the end of the inspection of the paper leaf P is described, but when the image is acquired, it is taken in from the input port 101. The timing for reading the serial number of the paper leaf P may be acquired, and the serial number and the timing may be associated with the captured image and stored in the overall image storage unit 62. With this configuration, when the operator confirms the entire image taken by the overall camera 115, the defect is generated from the entire image by inputting the serial number of the defective paper leaf P. The timing can be easily accessed, and the time for searching for the whereabouts of the defective portion of the paper leaf P can be shortened.

Further, in the above embodiment, the sensor unit for acquiring the image of the paper leaf P is the input port sensor unit 112A in the inspection unit 112, and the first sensor unit 112B to the sixth sensor unit used for inspecting the paper leaf P. Although it has been described in the case of sharing with 112G, it is not limited to this. For example, the sensor unit for acquiring the image of the paper leaf P may be arranged at a different position on the transport path 111 other than the inspection unit 112, or such a sensor unit and the first used for the inspection of the paper leaf P may be arranged. The sensor units shared with the sensor units 112B to the sixth sensor unit 112G may be mixed. With this configuration, sensor units can be provided at various positions on the transport path 111, and images of paper sheets P at different positions on the entire transport path 111 can be acquired.

Although some embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other embodiments, and various omissions, replacements, and changes can be made without departing from the gist of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.
