Description

  The present invention relates to an irregularity detection method and an apparatus therefor.

  In general, bookbinding for books, magazines, etc. is made by folding several pages printed on a single page into pages so that they are in page order, and then collecting the pages in page order. It is configured by binding. Here, the operation of superimposing the signatures in the order of pages is an operation of aligning the pages indicating the page of the paper, so it is called collation, and is usually performed by a collation machine.

  The collating machine includes a plurality of feeders along an endlessly rotating gathering chain, and each of the plurality of feeders can take out a signature from a stacked portion storing signatures with different printing surfaces. By sequentially dropping the signatures from the plurality of feeders onto the gathering chain, the signatures having different printing surfaces are overlapped in the page order.

  However, when collating with a collating machine, troubles such as messed up with other signatures or missing signatures are unavoidable. Since the same accident seems to have occurred in the bound books, there has been a problem that operations such as collection and disposal occur.

  For this reason, a collation machine is usually provided with a collation detection device that can detect a collation or the like. FIG. 6 is a conceptual diagram showing a conventional irregularity detecting device.

  The conventional irregularity detecting device includes a photographing unit 2 such as a CCD camera that can photograph the printing surface of the signature 1 at a predetermined position of all feeders, and a control unit that is connected to the photographing unit 2 and processes information of the photographing unit 2. 3, a position detection sensor (not shown) that can transmit the photographing timing of the signature 1 to the photographing means 2, and an external device (not shown) connected so as to combine information of all the control units 3 into one. The control unit 3 includes an A / D converter 4 that converts the printed surface of the signature 1 photographed by the control means into a predetermined signal, and a reference image that records the signal from the A / D converter 4. And a CPU 7 for processing information of the reference image memory 5 and the inspected image memory 6.

  When detecting a trouble such as a typographical error or a missing memorandum by the typographical detection device, first, a photographic signature 2 having a standard printing surface is photographed by the photographing means 2, and the standard image data is standardized via the A / D converter 4. The image is recorded in the image memory 5, and is then photographed by the photographing means 2 when the signature 1 having the print surface to be inspected reaches a predetermined position in accordance with the operation of the collating machine, and the A / D converter 4. The image data to be inspected is recorded in the inspected image memory 6 via the CPU 7, and the CPU 7 compares the information in the reference image memory 5 and the inspected image memory 6. If the two do not match, it is determined that there is a problem with a mess and a missing page, and the determination result is appropriately transmitted to an external device. Individual on the feeder And to detect the presence or absence of a trouble of erratic pagination and missing pages.

In addition, the following patent document 1 etc. already exist as prior art documents related to the disorderly collation detection device.
JP 2000-289368 A

  However, if the photographing means 2 such as a CCD camera photographs a part of the signature 1, even if the signature 1 has a different printing surface, if the photographing part is exactly the same, the overwriting and the missing signature are missed. Therefore, it is necessary to intentionally mix the signatures 1 of the adjacent feeders etc. manually to check the operation of detecting the disorder, and there is a problem that it takes much time and labor. In addition, when a collation (semi-finished product) including a typographical error is generated artificially, the disposal of the collation (semi-finished product) is not preferable in terms of environmental problems, and the wrong signature 1 is replaced with the original feeder. There was a problem that it was necessary to return to work. Furthermore, since the number of spare parts of the signature 1 is not large, there has been a problem that the operation check for detecting the irregularity cannot be sufficiently confirmed. Furthermore, when loading the signature 1 into the collating machine, one worker supplies the collation with different printing surfaces to the three adjacent feeders. It was especially often mixed.

  The present invention has been made in view of such a situation, and an object thereof is to provide a disorder detection method and apparatus capable of checking the operation of detecting a disorder or the like without human intervention.

In order to achieve the above object, the invention according to claim 1 is provided with a plurality of lines corresponding to signatures having different printing surfaces so as to collect and superimpose the signatures in page order in bookbinding, and on each line, A method for detecting disordered characters used in a collating means for detecting disordered characters by comparing reference image data registered in advance and image data to be inspected acquired from a signature,
The signature data is registered by photographing the signature on each line, comparing the reference data on one line with the reference data on the other line, and confirming the operation of detecting irregularities. This relates to the method of detecting a random order.

  In the invention according to claim 2, when the reference data on one line is compared with the reference data on another line and the reference data is the same, the comparison point of the reference data on one line is changed, The method according to claim 1, wherein the reference data is different.

  According to a third aspect of the present invention, there is provided a randomness detection method according to the first or second aspect, wherein the reference data on one line is compared with the reference data on another adjacent line.

  The invention described in claim 4 relates to the method of detecting irregularity according to claim 1, 2, or 3, wherein the reference data and the reference data on other lines are compared on all the lines.

  The invention described in claim 5 uses the same reference image data used for detection of disorder and the reference data used for confirmation of operation for detecting disorder, as described in any one of claims 1 to 4, It is related to.

The invention according to claim 6 is provided with a plurality of lines corresponding to signatures having different printing surfaces so as to collect and superimpose the signatures in page order in bookbinding, and reference image data registered in advance on each line. And a typographical detection device that detects typographical errors by comparing the inspected image data acquired from the signature,
A photographing means for photographing a signature on each line, and a control means connected to each photographing means;
The control means is configured to register the reference data from the photographing means, compare the reference data on one line with the reference data on the other line, and confirm the operation of detecting the typographical error. The present invention relates to an irregularity detecting device characterized by the following.

  The invention described in claim 7 relates to the irregularity detecting device according to claim 6, wherein the line is formed until the signature is overlapped on the feeder or the gathering chain.

  Thus, according to the first, sixth and seventh aspects of the present invention, the reference data of signatures registered on one line and the reference data of signatures registered on another line are compared. Thus, the operation for detecting the order of tampering is confirmed, so that it is not necessary to check the operation for detecting tampering that is intentionally mixed manually, thereby reducing labor and shortening the time for checking the operation for detecting tampering. In addition, there is no artificially generated collation (semi-finished product) that includes mess, so there is no environmental impact in the disposal of the collation (semi-finished product), and the wrong signature is returned to the original line. This can be eliminated. In addition, since the operation of detecting the tampering is confirmed by comparing the reference data, it is not necessary to consider the number of spare copies of the signature, and the operation of detecting the tampering can be sufficiently confirmed.

  According to claim 2, when the reference data on one line is compared with the reference data on another line and the reference data is the same, the comparison point of the reference data on one line is changed, and the reference data is changed. By making a difference, even if the comparison point is exactly the same on a signature with a different printing surface, the comparison point is changed and a difference is created, so that it is possible to suitably prevent oversight of detection of a mess, etc. it can.

  According to the third aspect of the present invention, when the reference data on one line is compared with the reference data on another adjacent line, the operation of detecting disorder is focused on the adjacent line. Even if the person mistakenly mixes the adjacent signatures, it is possible to particularly preferably prevent the detection of a disordered signature or the like.

  If the comparison between the reference data and the reference data on the other lines is performed on all the lines as described in the fourth aspect, it is possible to confirm the operation of detecting disordered characters on all the lines.

  As shown in claim 5, when the reference image data used for detecting the tampering and the reference data used for checking the operation for detecting the tampering are used as the same, the detection of the tampering and the operation checking for the tampering detection are performed by common data. The number of parts can be reduced and information processing can be simplified.

  As described above, according to the present invention, it is possible to obtain an excellent effect that it is possible to confirm the operation of detecting a disorder or the like without any manual intervention.

The part which attached | subjected the code | symbol represents the same thing.

  The irregularity detection device is for detecting an irregularity that is connected to the imaging means 2 and processes the information of the imaging means 2 so as to be attached to the collating machine. The control unit 8, the control unit (control unit) 9 for confirming the operation of detecting disordered characters that is connected to all the control units 8 and processes the mutual pattern matching information, and the imaging unit 2 indicates the timing of capturing the signature 1. And a position detection sensor (not shown) that communicates with each other, and an external device (not shown) that is connected so that information of all the control units 3 is integrated. Here, the photographing means 2 such as a CCD camera is used for a predetermined position of a plurality of lines corresponding to the signatures 1 having different printing surfaces, specifically, until the signatures 1 are overlapped at a predetermined position of the feeder or a gathering chain. It is arranged at a predetermined position.

  The irregularity detection control unit 8 includes an A / D converter 10 that converts a printed surface of the signature 1 photographed by the control means into a signal, a reference image memory 11 that records a signal from the A / D converter 10, and a target image. An inspection image memory 12 and a CPU 13 for processing information of the reference image memory 11 and the inspection image memory 12 are provided.

  On the other hand, the control unit 9 for checking the operation of detecting the order of irregularities includes a reference data memory 14 for recording the reference data of the image from the control unit 8 for detecting the order of irregularities, and information such as reference model coordinates from the control unit 8 for detecting the order of irregularities. Is stored, and a CPU 16 is provided for processing information such as reference data and reference model coordinates in a predetermined flow. Here, the control unit 9 for confirming the operation of detecting disorder may appropriately transmit the processed information to the external device.

  The operation of the embodiment for carrying out the present invention will be described below.

  When confirming whether or not the disorderly detecting device can be driven properly, as shown in the flow of FIG. 2, the signature 1 having a different printing surface is first set at a predetermined position of the collator. (Process A), prepare the operation for confirming the operation of detecting the order of irregularities so that the control unit 8 for detecting the order of irregularities and the control unit 9 for confirming the operation of detecting the order of irregularities can be operated (Step B). The machine is operated once (process C), the signature 1 is sent out partly by each feeder (process D), and the signature 1 (reference registration mode) having a reference printing surface is obtained by the photographing means 2 such as a CCD camera. ) (Step E), and the reference data is registered in the reference image memory 11 and the reference data memory 14 via the A / D converter 10 (step F). Here, photographing (step E) and registration of reference data (step F) of the signature 1 (reference registration mode) having the reference printing surface are performed on all the lines corresponding to the signatures 1 having different printing surfaces. The reference data registration (step F) may be automatic or manual. Further, when the reference data is sent from the photographing means 2 to the reference image memory 11, the reference data memory 14, etc., it is preferable to send information such as the reference model coordinates to the reference model coordinate memory 15 at the same time.

  After the registration of the reference data, the CPU 16 of the control unit 9 for checking the operation of detecting the disorderly order converts the reference data on one line (NO1 in FIG. 1) to the reference data on another adjacent line (in FIG. 1). NO2) is compared (mutual pattern matching) (process G), and it is determined whether the reference data of both are different or coincident (process H). Here, when the reference data of the two are different (determination Y of process H in FIG. 2), as an appropriate mode in which the operation of detecting disorder can be confirmed, whether or not the comparison has been completed for all the lines. When the process proceeds to step (process I) and the reference data of both match (determination N of process H in FIG. 2), it is recorded as an improper mode in which the operation check of disorder detection cannot be confirmed (process J). The process proceeds to the next stage (step I) as to whether or not the comparison has been completed.

  After moving to the next stage (step I) of whether or not the comparison has been completed for all lines, the comparison is made because the comparison has not been completed for all the lines (determination N of step I in FIG. 2). By shifting the two reference data to the next (process K) and returning to the previous comparison stage (process G), the reference data on the next one line (NO2 in FIG. 1) and the other adjacent data The reference data on the line (NO3 in FIG. 1) is compared (mutual pattern matching). In this way, the reference data and other lines are subjected to a loop process that repeats the comparison stage (process G, process H, process J), confirmation of completion of all lines (process I), and shift stage of reference data (process K). Comparison with the above reference data is performed on all lines, and after completing the comparison on all lines (determination Y in step I in FIG. 2), an inappropriate mode in which the operation confirmation of disorder detection cannot be confirmed. The process proceeds to the step of checking (process L) (the flow continues from FIG. 2 to FIG. 3, and the contacts in FIGS. 2 and 3 are indicated by α).

  After proceeding to the stage of checking the inappropriate mode in which the operation check of the disorderly detection cannot be confirmed (process L), it is determined whether or not the inappropriate mode is registered in the previous stage (process J) (process M). If there is no appropriate mode (determination N in step M in FIG. 3), the operation for detecting the collation is started (step Q) and the collating machine is finally driven (step Q). R). On the other hand, when there is an inappropriate mode (determination Y in step M in FIG. 3), the comparison within the range of the photographing means 2 is performed so that the reference data is changed by changing the comparison point of the reference data on one line. It is determined whether or not the change can be dealt with by changing the target model (step N). When the change can be dealt with by changing the comparison target model (determination Y of step N in FIG. 3), the comparison of the reference data is made by changing the comparison target model. If the reference data is changed by changing the point (step O) and cannot be dealt with by changing the model to be compared (determination N in step N in FIG. 3), the reference data is changed by changing the shooting position of the shooting means 2. The reference data is made different by changing the comparison point (process P). Then, after changing the reference data comparison point and making the reference data different, each of them detects that the confirmation of the irregularity detection operation has been completed and starts the irregularity detection operation (step Q), and finally drives the collator. (Step R).

  Here, the change of the comparison object model will be described in detail by changing the comparison point of the reference data so as to make the reference data different. As shown in FIG. 4, the photographing means 2 such as a CCD is arranged on the printing surface of the signature 1. The predetermined range 17 is photographed, and in the predetermined range 17 of the photographing part, a smaller range (indicated by a to e and a ′ to e ′ in FIG. 4) is determined by the control unit 8 for detecting disorder. One of them is the model for comparison. Usually, in the comparison stage (process G, process H), processing is performed by comparing arbitrary comparison target models (for example, a and a ′ in FIG. 4), and there is an improper mode (a signature 1 with a different printing surface). In the case where the model to be compared is the same, in FIG. 4, the model to be compared is changed in accordance with NO1 a, c to e and NO2 a ′ and c ′ to e ′ are the same) (step O). For example, by moving the comparison target model in the up-down direction or the left-right direction in order in both comparisons by the control unit 8 or the like for detecting disorder (for example, in the case of NO1 in FIG. 4, the model is moved in order of a → b → c → e, Similarly, in NO2, the models to be compared are made different at any position (the positions of b and b ′ in FIG. 4), in order of movement from a ′ → b ′ → c ′ → e ′ so as to correspond to NO1. ). Here, the process of changing the comparison target model may be performed manually by viewing a captured image on a display or the like, or may be performed automatically in accordance with a predetermined program.

  Further, the change of the photographing position of the photographing means 2 so as to change the reference data by changing the comparison point of the reference data will be described in detail. The photographing means 2 such as a CCD usually has a predetermined range on the printing surface of the signature 1. As shown in FIG. 5, when the characters and the like in the predetermined range 17 of the photographing part are the same, it cannot be dealt with by changing the comparative model (determination N in step N in FIG. 3). The photographing position of the means 2 itself is changed (for example, NO1 in FIG. 5 is changed from 17 to 17a, and NO2 is changed from 17 to 17a ′). Here, the process of changing the photographing position of the photographing means 2 may be performed manually or automatically.

  On the other hand, when the operation of detecting the order of errors is completed and the operation of detecting the order of errors is started (step Q), the reference data used for checking the operation of the detection is used as the reference image data used for detecting the order of errors. When the signature 1 having the printing surface to be inspected reaches the predetermined position as the machine is operated, the image capturing means 2 captures the image data to be inspected via the A / D converter 10. 12, and the CPU 13 compares the reference data and the image data to be inspected. If the two match, it is determined that there is no trouble of the mess and missing pages. Thus, the determination result is appropriately transmitted to an external device, whereby the disorderly detection device separately detects the presence or absence of problems of irregularities and missing pages on all feeders.

  As described above, according to the embodiment of the present invention, the reference data of the signature 1 registered on one line is compared with the reference data of the signature 1 registered on the other line, thereby detecting a typographical error. Therefore, it is possible to eliminate the need for checking the operation of detecting the tampering that is intentionally mixed manually, thereby reducing the time and the time for checking the operation of detecting the tampering. In addition, there is no artificially generated collation (semi-finished product) that includes mess, so there is no environmental impact in the disposal of collation (semi-finished product), and the wrong signature 1 is restored to the original line. The work of returning can be made unnecessary. Furthermore, since the operation for detecting the tampering is confirmed by comparing the reference data, it is not necessary to consider the number of spare copies of the signature 1, and the operation for detecting the tampering can be sufficiently confirmed.

  If the reference data on one line is compared with the reference data on the other line and the reference data is the same, the reference data on one line is changed and the reference data is changed to change the reference data. Even if the comparison point is exactly the same for the signatures 1 with different surfaces, the comparison point is changed and a difference is created, so that it is possible to suitably prevent the detection of an irregularity or the like.

  When comparing the reference data on one line with the reference data on the other adjacent line, the confirmation operation of the disorderly detection on the adjacent line is focused. Even in the case where the signatures 1 are mixed, it is possible to particularly preferably prevent the detection of a disordered signature or the like.

  If the comparison between the reference data and the reference data on other lines is performed on all the lines, it is possible to check the operation of detecting the disorderly order on all the lines.

  If the reference image data used for detecting the tampering and the reference data used for checking the tampering detection are used as the same data, the tampering detection and the tampering detection operation confirmation are performed using common data, thereby reducing the number of parts. Information processing can be simplified.

  It should be noted that the disorderly detection method and apparatus of the present invention are not limited only to the above-described embodiments, meaning that the disorderly letters include all the faults in the signatures, and the operation confirmation of the disorderly letter detection is As long as the reference data can be compared with the reference data of other routes, it may be performed in other steps, the type and number of photographing means are not limited to one, and the present invention Of course, various changes can be made without departing from the scope of the present invention.
