Description

  The present invention relates to a randomness inspection system that inspects and controls irregularities when collating forms and the like.

2. Description of the Related Art As an inspection device for booklets, missing pages, etc. (collectively referred to as “random pages” in this specification), a book-order inspection device using a CCD camera is known.
For example, as shown in FIG. 1, in the saddle stitching machine, the forms stocked for each of the collating pieces 3A to 3F are taken out one by one by a form taking-out mechanism (not shown) of each of the collating pieces 3A to 3F. (Gathering chain) It is mounted in order on the ridge 2 arranged in 1, formed as a collation bundle 5, and conveyed to the downstream saddle stitcher 4.
Here, CCD cameras 6a to 6f for checking the collation are arranged for each of the collating pieces 3A to 3F, the form images placed on the basket 2 are photographed, and the captured images are output to the controllers 7A to 7C. It is configured as follows.
The controllers 7A to 7C compare the photographed image with a pre-registered reference image to detect the presence or absence of an image abnormality in the signature, and detect the image abnormality detection signal and the CCD cameras 6a to 6f. Based on the timing to perform and the signature feed amount of the conveying device (gathering chain) 1, it is detected which collating piece has an abnormality, and signals for identifying the collating bundle in which the abnormality has occurred are sent to the saddle stitching machine 4 and the ejecting machine 14. Has an abnormal signal output means for outputting the signal.
Then, the saddle stitcher 4 that has received the abnormal signal conveys downstream without performing saddle stitching on the collated bundle in which an abnormality has occurred, and the downstream discharger 14 transfers the abnormal collated bundle to the outside A It is configured to discharge.

  Recently, in order to reduce the cost of the inspection apparatus, a single controller corresponding to a plurality of CCD cameras has appeared. (Patent Documents 1 and 2)

JP 2003-191662 A JP 2001-246870 A

However, managing a large number of camera devices with one or a small number of controllers results in an increase in the distance between the two devices. For example, an inspector (operator of the collation device) finds an abnormality in the collation device. When changing the setting value of the collating apparatus, it is necessary to go back and forth between the controller and the collating piece, which is a heavy work burden for the inspector. In particular, a horizontal collating machine / bookbinding machine with a large number of pages has a very large total length, and the burden is very large.
Further, since the name of the person in charge of inspection does not remain in the inspection record, there is a problem that it is not possible to clarify from the operation history which inspector has performed an operation such as changing the setting value for what reason.

Therefore, according to the present invention, in a collation apparatus including a plurality of collation piece apparatuses, an image of a printed matter taken out one by one from the collation piece apparatus is taken as an inspection image, and the inspection image and a pre-stored reference image are obtained. A random inspection system that compares and inspects a collation and controls collation in the collation piece device,
A code information management device that is offline from the random inspection system and outputs at least operation code information for specifying an operator and operation content;
A code display medium to which at least the operation code information is input, which is output from the code information management device;
Random inspection information is output from an image capturing unit that is disposed in each of the plurality of collating piece devices and captures the inspection image and the code display medium, inspection image information from the image capturing unit, and reference image information stored in advance. A randomness inspection device that outputs the operation code information from the imaging unit as setting information,
A collation device and a plurality of the above-mentioned collation inspection devices, a display unit for displaying the input of the above-mentioned collation inspection information and the setting information, and the collation device and the above-mentioned collation inspection based on the setting information and the inspection information A line control unit having control means for controlling the device;
A code display medium on which operation code information necessary for restarting operation is displayed when the line control unit is stopped by the line control unit based on the irregularity inspection information from the irregularity inspection device. When the selected code display medium is imaged onto the imaging unit corresponding to the collation piece device in which the disorder is generated, the setting information corresponding to the operation code information is transferred from the irregularity inspection apparatus to the line control. A random inspection system characterized by being output to the unit.

  With this configuration, the inspector (the operator of the collation apparatus) resumes the operation of the collation piece apparatus from the code display medium owned in advance when the collation piece apparatus stops due to the occurrence of disorder. The selected operation is selected by appropriately selecting a code display medium in which operation code information necessary for performing the operation is input, and imaging it with the imaging unit of the collation inspection apparatus arranged in the stopped collation piece apparatus Based on the code information, the stopped operation of the collating apparatus can be resumed. Therefore, when the inspector checks the collation piece apparatus that has been stopped due to the occurrence of an irregularity, the inspector resumes the operation of the collation apparatus from the location of the collation piece where the irregularity occurred without accessing the remote line control unit. Work efficiency is very good.

  According to the present invention, the code information management device includes a printing device that prints the code display medium.

  With this configuration, the code display medium can be easily prepared as appropriate, and the work of the inspector can be facilitated.

  The code display medium may be a portable terminal having a display unit that displays code information, and the portable terminal inputs at least the operation code information output by the code information management device. In this case, the random inspection inspection control system is configured to display on the display unit.

  With this configuration, the code information output from the code information management device can be easily taken into the portable terminal owned by the inspector, and the fetched code information can be displayed on the display unit of the portable terminal. Since it is also easy to display, the work of the inspector becomes easy.

Further, according to the present invention, the line control unit has a portable memory, and collates and manages time information, operation information of each collating piece device, the inspection information, the setting information, and the operation code information in the portable memory. It is memorized as information,
The code information management device reads the collation management information stored in the portable memory and manages the collation management information in the multiple collation piece devices; did.

With this configuration, the name of the operator who has selected such a driving operation is recorded as an operation history in the line control unit, so that it can be effectively used for subsequent analysis processing.
Also, since the information management of collation management information, which is a relatively large information processing burden, can be performed by an off-line code information management device without being performed by each line control unit, It can be built at low cost.

  Since the present invention is configured in this manner, the work load on the inspector in the random inspection control system is reduced. In addition, information management of collation management information can be performed accurately, and the system can be constructed at low cost.

Inspection information storage means 22b for storing inspection information in the inspection apparatus 20, equipment information storage means 22c for preliminarily writing and storing device identification information specific to the collating apparatus 10 and each collating piece as specific code information in an EEPROM, etc. The reference image stored in the device information storage unit 22c is compared with the signature image from the collation image processing unit 21a based on the setting information from the line control unit 30, and the signature image that becomes a disorder is identified and inspected. The information storage means 22b stores and stores the inspection information via a network (I / O), which will be described later. And a frame control unit 22d to output the. Further, the frame control unit 22d outputs QR code information subjected to captured image processing by the QR code read image processing unit 21b to the line control unit 30 via a network (I / O).

Further, in this system, a line control unit 30 is provided separately from each inspection-side control unit 22 in order to control the plurality of random inspection devices 20-1 to 20-n via a network (I / O). . The line control unit 30 is configured to control the entire system with one or a minimum number of units.
The line control unit 30 has various settings in the standard time supply means 30b (time server 30b-1 and radio clock 30b-2) for supplying a standard time common to each collating piece, the inspection side control unit 22 for each collating piece device, and the like. Input operation means 30d for inputting information, display means 30c for displaying the input operation by the input operation means 30d, the operating state of each of the disorder checking devices 20, and QR code control means 30e for restoring QR code information from the disorder checking device , And error totaling / analyzing means 30f for totaling and analyzing the operation information restored by the QR code control means 30e and the inspection information from each of the randomness inspection devices 20-1 to 20-n, and the error totaling / analyzing means 30f A portable memory 30g that can store the analyzed collation management information and take it offline, and a starter 15 Start signal 31, and a main control unit 30a for controlling the line control unit 30 receives an input signal from the pulse signal and the input operation unit 30d from the encoder 32.
Further, the main control means 30a controls the collation apparatus and the collation inspection apparatus based on the setting information and the inspection information, and an error occurs in the collation apparatus due to the occurrence of the irregularity, and the random inspection from the disorder inspection apparatus. When the information (inspection information) is input, the entire collating apparatus is automatically stopped, the setting information is output to the random collating apparatus based on the setting information by the input operation means 30d, and the stop switch in the collating apparatus is turned on. It has a function of forcibly stopping the entire collating apparatus when operated by an operator.

The starter 15 generates a start signal 31 for each rotation of the drum 14, and the counter 22a in each inspection-side control unit 22 counts up the start signal 31 supplied through the main control means 30a. Therefore, the signature of each collating piece can be specified by the count number of the counter 22a.
The encoder 32 generates a pulse signal in synchronization with the rotation of the drum 14, and the reference position (rotation angle position) of the claw provided on the drum 14 with respect to the signature storing means 11 is set by the pulse signal. The

The inspection results in each of the random inspection devices 20 are the inspection determination result (OK or NG), the measurement correlation value, the measurement density value, the measurement density deviation value, the inspection count, the inspection date and time, and the information accompanying the inspection image (the inspection image is attached Or the like) is stored as inspection information in the portable memory of the inspection information storage means 22b, and an inspected image corresponding to the inspection information is also stored.
However, since a portable memory is used for the inspection information storage unit 22b, there is a limit to the maximum storage capacity. On the other hand, a relatively large storage capacity is required to store the inspection image.
Therefore, as shown in FIG. 4, the piece control means 22d in each inspection-side control unit 22 includes a correlation value detection means 22d-1 for detecting the correlation value between the image to be inspected and the reference image, and the detected correlation value is Correlation value classification determination means 22d-2 for determining which classification of correlation values divided into a predetermined number, and storage retention determination for determining whether or not an inspection image should be stored in the inspection information storage means 22b Means 22d-3 are provided, and by these means, an inspection image whose correlation value with the reference image is equal to or smaller than a predetermined correlation value is selected, and only the selected inspection image is inspected in the inspection information storage means 22b. Stored and stored as information.

The piece control means 22d further includes an operation information creation means 22d-4. The operation information creation means 22d-4 uses the count information from the counter 22a, the collation piece specifying information from the device information storage means 22c, and the line. Operation information is created based on the standard time and the like from the control unit 30 side.
The operation information is stored and stored in the portable memory of the inspection information storage unit 22b together with the inspection image in association with the inspection information.
Among the operation information, information other than items specified at the time of inspection, such as a determination result, an inspection counter value, and inspected image specifying information, for example, device information such as a collating machine line number and a collating piece number, is stored in the line control unit 30. The input operation unit 30d is stored in the device information storage means 22c of the corresponding randomness inspection apparatuses 20-1 to 20-n, and these are inspected into the portable memory of the inspection information storage means 22b. It is appropriately read and used when writing information.
Also, the inspection date and time of the operation information includes the time signal from the standard time supply means such as the time server 30b-1 and the radio clock 30b-2, which is similarly sent to each of the random inspection devices 20-1 to 20-n through the line control unit 30. Since it is supplied in common, it is created using the signal.
Therefore, all the operation information stored and stored in each portable memory 22b-1 is created using the same standard time.
Further, these operation information and inspection information (random inspection information) are output from the piece control means 22d to the line control unit 30 via the network (I / O) as control information necessary for controlling the entire collating apparatus. Is done.

Furthermore, as shown in FIG. 5, the random inspection system of the present invention includes the random inspection devices 20-1 to 20-n provided on each collating piece connected online with the line control unit 30 via the network. Is separately provided with an offline code information management device 40.
The code information management device 40 reads various collation management information stored in the portable memory of the randomness inspection device 20 or the line control unit 30 and manages them offline, and is imaged by the imaging means 21. It has a function for inputting QR code information to a code display medium.

  Among these, as a function to be managed off-line, a portable memory used for the inspection information storage means 22b in the randomness inspection devices 20-1 to 20-n and a portable memory 30g used for the line control unit 30 are inserted. Thus, portable memory reading means 46 for reading data from these portable memories, collation management information management means 47 for organizing the data read inspection information and storing it as collation management information, It has a display means 42 and an input operation means 43 to the CPU.

Further, as a function for inputting QR code information to the code display media 50 and 51 picked up by the image pickup means 21, QR code information storage means 41 for pre-registering and storing QR code information, and the QR code information Display means 42 for displaying the QR code information read from the storage means 41, input operation means 43 to the CPU, operation code information (code information for specifying the operator and code information for specifying the operation content) QR code information management means 44 that manages as collating piece information (inspector ID, setting value, release, other setting items) such as the operation history, and QR code information to be input to the code display media 50 and 51 A code creating unit 45 is provided.
Further, the printer includes a printing device 48 for inputting QR code information created by the QR code creating means 45 to the code display media 50 and 51.

The operation of the randomness inspection system of the present invention configured as described above will be described below.
The irregularity inspection apparatus 20 is a main part of the irregularity inspection system of the present invention, and its imaging means 21 is constituted by a collation image processing unit 21a and a QR code reading image processing unit 21b, and is always a collation image processing unit. The camera device 21a monitors the messiness, and if messiness occurs, the inspection information is output to the line control unit 30 via the network (I / O). The device is automatically stopped.
As described above, when the collation apparatus is automatically stopped due to an error or the collation apparatus 10 is forcibly stopped by the stop switch, the operator has generated an error in order to restart the operation. After confirming the state of the colloquial piece device (this is assumed to be 10-m), if necessary, the inspection level of the random collation inspection device 20-m in the collating piece device 10-m is reset and the operation is resumed. Instruction is required.

Therefore, the operator selects the code display mediums 50 and 51 on which the QR code information necessary for instructing the resumption of operation of the collating piece apparatus 10-m is selected, and selects the collating piece apparatus 10-m that is stopped. The imaging unit of the arranged disorder checking apparatus 20-m is caused to take an image.
The code display media 50 and 51 are provided with an operator ID (identification number), a main power ON / OFF command signal of the collation apparatus 10, and a signal for setting automatic stop conditions (for example, a collation inspection apparatus) by QR code. Is a signal for setting an automatic stop signal to be output when the number of irregularities is detected continuously, such as a signal for setting the number of irregularities as a condition), a signal for canceling the error of the collating piece apparatus, or the irregularity inspection apparatus 20 A signal or the like for resetting the storage in the inspection information storage means of -m to 0 is input. As described above, the QR code information input to the code display media 50 and 51 includes at least operation code information for specifying the operator and the operation content.
Therefore, when the operator changes the setting value of the randomness inspection device 20, the operation code information corresponding to the content to be changed and the operation code information corresponding to the respective ID information are displayed as QR code information. The code display mediums 50 and 51 are selected, and are read (made to be imaged) by the imaging means 21 in the target collating frame device.

When the QR code image input (printed) to the selected code display medium 50 or 51 is captured by the imaging unit 21, the image processing unit of the imaging unit 21 detects a change in the captured image. An interrupt signal is output, and the image processing mode is switched from the collation image mode to the QR code reading image mode.
The captured QR code information is subjected to image processing by the QR code reading image processing unit 21b, and the QR code recognized by the randomness inspection device 20 by the QR code determination unit 22d-5 (FIG. 4) of the frame control unit 22d. It is determined whether the information is information, and if it is determined that the QR code information is recognized by the irregularity inspection device, the QR code information is included in the QR code control means 30e of the line control unit 30 It is sent to the analysis means 30f. Here, whether or not it is a recognizable QR code is determined whether or not it is QR code information by comparison with a QR code standard stored in the QR code determination unit 22d-5 in advance.
Next, the QR code control means 30e restores the received QR code information as an operation item, and the control signal is output to the randomness inspection apparatus 20-m and the collation apparatus 10 via the main control means 30a. The operation information such as the inspector (ID number) who operated the collating device 10 with the QR code, the setting item operated, the cause of the operation, etc. is read for each collating frame, and the error code / analysis means 30f reads the QR code. All the setting item information sent as an image is totaled, and the cause of the cause of the error is analyzed.
This makes it possible to grasp the characteristics of each collating piece device and set the inspection setting value of the random collation inspection device in the best state.
The error count and analysis results are stored in the portable memory 30g and used in the code information management device 40 described later.

Next, some examples of creating the code display media 50 and 51 for the operator to select are described.
When the code display media 50 and 51 are created using the code information management device 40 provided offline, the QR code creation means 45 shown in FIG. Each of the operation information is registered to create QR code image data, which is read and stored in the portable terminal 51, the QR code image can be displayed on the display of the portable terminal, and the mobile phone that displays the QR code information The type terminal 51 is assumed.
Alternatively, the created QR code image is displayed on the display means 42, and the image is printed using the attached printing device 48 to create the QR code sheet 50.
Alternatively, the QR code image data of the setting item is output from the PC and input to the attached memory of the portable terminal 51, and the attached memory is returned to the portable terminal 51 for use.
Further, a QR code printed on a sheet or the like or displayed on the display means 42 can be photographed with a camera attached to the portable terminal and captured as image data.
Each image data is stored with an operation item name. It is also possible to assign each item to a telephone number using dedicated software. If you use a dedicated mobile terminal sold for general purpose, you can input more easily.
By reproducing the image data captured in the portable terminal on the display of the portable terminal, the reproduced image can be made to function in the same manner as the QR code sheet 50.

In the code information management device 40 set to offline, the setting information and operation information of each collating piece device operated by the QR code image is read from the portable memory 30g by the portable memory reading means 46, and the QR code information storage means 41 is read. Remember me.
This setting information and operation information is managed by the QR code information management means 44 as collation piece information such as an operation history of each collation piece (as described above, an inspector ID, a set value, cancellation, and other setting items).
This collating piece information can be confirmed by the attached display means 42, and input / output means 43 can input / output information retrieval items and input / output additional recording items (memos).
The collating piece information stored in the portable memory 30g can also be displayed by the display device 30c of the line control unit 30 or the display means 42 of the code information management device 40.

Next, the operation flow of the inspection system of the present invention will be described with reference to FIG.
The operator selects the code display mediums 50 and 51 in which operation information (operation code information) necessary for processing a typo in the collation piece apparatus is input, and the collation inspection apparatus 20 to which the collation piece apparatus corresponds is selected.

  In this manner, the line control unit 30 is connected online to the randomness inspection apparatuses 20-1 to 20-n, and the setting items operated by the QR code images input from the respective imaging means 21 in the randomness inspection apparatuses 20-1 to 20-n. Therefore, it is not necessary for the operator to access the line control unit that is physically far away, so the work load is significantly reduced. In other words, since only the QR code is read by the image pickup means (camera device) for each collating piece device, an operation instruction can be given to the irregularity detecting device. Therefore, it is not necessary to go back and forth with a relatively long movement distance, and work efficiency is improved.

In addition, this random inspection system has the following effects.
(1) Even in an existing irregularity inspection system, it is only necessary to introduce a design change in the control system in the line control unit 30 and a design change in the image processing unit in the irregularity inspection apparatus 20, so that it can be realized at a low cost. .
(2) Based on the history of ID (operator identification number), collating piece device, operation items, etc., it is possible to easily analyze the factors such as who has operated for what reason.
(3) Since many QR codes can be stored when a portable terminal is used, a wide variety of operation instruction items can be provided. The selection of the QR code corresponding to the operation item can be directly input from the input key of the terminal, which is convenient and prevents the camera device from erroneously reading another QR code.
(4) When the QR code is read and input from the image capturing device of the collating piece device, inspection information can be automatically transmitted to the collating piece device, so that the operation history is stored without error, and the cause after the problem occurs Easy to investigate.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the invention described in the claims. Examples of modifications include the following.
(1) In the embodiment described above, a portable memory is used as the storage means of the inspection information storage means 22b. However, the minimum required inspection image such as a reference image is stored without being a portable type. The inspection information required as collation management information can be output to the line control unit 30 and stored in the portable memory 30g.

(2) In the above-described embodiment, the operation is described while the collating apparatus 10 is stopped due to the occurrence of a disordered letter, but the setting change is necessary not only during the collating apparatus being stopped but also during operation. In this case, by setting the necessary code display media 50 and 51, the setting of the collation inspection apparatus can be changed.

(3) In the above embodiment, a known QR code (registered trademark) is used as the code information. However, other information codes can be used without being limited to the QR code.
