  Next, embodiments of the present invention will be described with reference to the drawings. An example of the configuration of the collation inspection system of the present invention is shown in FIG. In FIG. 1, 100 is a continuous sheet, 101a to 101h are unit sheets (cut sheets), 10 is a collation inspection PC (parsonal computer system), 20 is a barcode reading unit, 30 is a sheet supply unit, and 40 is a sheet. A conveyance part, 50 glue application part, 60 is a collation part, 70 is a press part, 80 is a stack part.

First, the collating machine will be described along the flow of the paper that is the target of the collation inspection.
The continuous sheet 100 is a sheet before the unit sheets 101a to 101h to be collated are cut (cut). In the example shown in FIG. 1, the continuous paper 100 has a form in which perforations are applied at predetermined intervals in the lateral direction (perpendicular to the traveling direction), and the portions are folded and stacked with the portions as folds. . The continuous paper 100 in that form is drawn from the top and supplied to the paper supply unit 30, and is cut into unit papers 101 a to 101 h in the paper supply unit 30.

  The unit sheets 101a to 101h are arranged in the order of collation in the continuous sheet 100, and are conveyed in the order of collation in the sheet conveyance unit 40 after being cut in the sheet supply unit 30. Different variable information is printed on each of the unit sheets 101a to 101h. The variable information includes at least product information including a booklet serial number, the total number of sheets, and the number of sheets. The product information is printed as a print code such as a barcode or a two-dimensional code on each of the unit sheets 101a to 101h. The print code is printed at a predetermined same place common to each of the unit sheets 101a to 101h.

  The unit sheets 101a to 101h travel through the sheet conveying unit 40 and reach the glue coating unit 50 (see the unit sheet 101d). The glue coating unit 50 applies glue to predetermined glue coating sites on the unit sheets 101a to 101h.

  Further, the unit sheets 101a to 101h travel through the sheet conveying unit 40 and reach the barcode reading unit 20 (see the unit sheet 101g). In the example shown in FIG. 1, the barcode reading unit 20 is provided immediately before the collating unit 60. By providing the barcode reading unit 20 immediately before the collating unit 60, the process from the inspection to the collating unit 60 can be minimized, and the reliability of the inspection can be improved. The barcode reading unit 20 reads a print code printed on the unit sheets 101a to 101h. The print code is a print code of product information including at least the booklet serial number, the total number of sheets, and the number of sheets.

  The barcode reading unit 20 is an example of a code reader. The code reader is a device that reads a bar code or a two-dimensional code. JAN / EAN (ISO / IEC15420), CODE39 (ISO / IEC16388), NW-7 (ISO / IEC16390), ITF (ISO / IEC15390), CODE128 (ISO / IEC15417), and DataMatrix for two-dimensional codes. (ISO / IEC16022), QR Code (ISO / IEC18004), MAXI code (ISO / IEC16023), PDF417 (ISO / IEC15438), and the like exist, but the present invention is limited by the types of barcodes and two-dimensional codes. Not.

  The unit sheets 101a to 101h are supplied to the collating unit 60 immediately after the print code is read (see the unit sheet 101h). The collating unit 60 collates the unit sheets 101a to 101h. At this time, collation is performed in units of booklet serial numbers in the product information of the unit sheets 101a to 101h. That is, the unit sheets 101a to 101h are collected into a booklet by collation.

The booklet obtained by collation is supplied to the press unit 70. The press unit 70 presses (presses) the booklet in parallel planes, thereby ensuring the gluing between the unit sheets 101a to 101h in the booklet and flattening the shape of the booklet.
The booklet obtained by pressurization is supplied to the stack unit 80. The stack unit 80 stacks and holds booklets.

This completes the description of the collator. Next, components in the collation inspection system of the present invention will be described.
The collation inspection PC 10 is a part that mainly performs data processing in the collation inspection system of the present invention. The collation inspection PC 10 is a personal computer system, but may be another data processing system such as a programmable sequence controller. The collation inspection PC 10 can be realized by hardware and software of a data processing system.

  An example of the configuration of the collation inspection PC 10 is shown in FIG. 2 as a block diagram. As shown in FIG. 2, the collation inspection PC 10 includes a product information storage unit 11, a pass / fail determination unit 12, a range determination unit 13, a bookbinding history generation unit 14, a bookbinding history storage unit 15, a display unit 16, and a printing unit 17. . Further, the collation inspection PC 10 includes a barcode reading unit 20, a paper supply unit 30, a paper conveyance unit 40, a glue coating unit 50, a collation unit 60, a press unit 70, and a stack unit 80, which are the parts of the collation machine described above. , Etc., or information can be passed directly or indirectly via a control unit (not shown) of the collator. By the mutual exchange of this information, the collation inspection PC 10 performs an operation suitable for the operation state of the collation machine, for example, interlocking between start and stop in collation and inspection, synchronization in collation and inspection, and the like. Further, the collation inspection PC 10 can output a predetermined command based on the inspection result, for example, a command such as operation stop, to the collation machine.

  The product information storage means 11 stores at least product information including a booklet serial number, the total number of sheets, and the number of sheets. The booklet serial number in the product information is a number assigned as a serial number to each booklet. The total number is the total number of unit sheets in each booklet. The number of sheets is a number assigned as a serial number to each unit paper in each booklet. For example, if the booklet serial number is 101 and the booklet has a total number of 5 sheets, the booklet will contain 1/5, 2/5, 3/5, 4/5 in the notation of (sheet number) / (total number of sheets). , 5/5 unit sheets are present. FIG. 3 shows an example of the relationship between the booklet serial number of the unit paper, (sheet number) / (total number of sheets), and the transport position in the collator. In the example shown in FIG. 3, collation is performed in ascending order of numbers.

Product information is not limited to the booklet serial number, total number, and number of sheets. Customer code for identifying the customer, item code for identifying the item, progression unit category code for identifying the category into which the item is divided into progression units, and data processing date for using the date on which the data was processed as the category unit , Etc. can be included in the product information.
Product information to be collated is read into the collation inspection PC 10 from a production management system (not shown) or the like and stored in the product information storage means 11 before collation is performed.

  The pass / fail judgment means 12 compares the product information obtained by the bar code reader 20 reading the print codes printed on the unit papers 101a to 101h with the product information stored in the corresponding product information storage means 11 to pass (match). ) Or not (mismatch). The product information stored in the product information storage unit 11 includes the order of printing on unit sheets in the continuous sheet 100. Then, association between the two pieces of product information is performed based on the order. First, compare the booklet serial numbers, and then compare (number of sheets) / (total number of sheets). If there is even one non-matching place, it is determined as no (mismatch).

  When the pass / fail judgment means 12 determines NO, the range determination unit 13 determines NO for unit sheets in the range that the determination affects together with the unit sheet. The range affected by the determination is, for example, one of the unit sheets in a booklet with a total number of 5 sheets collating 1/5, 2/5, 3/5, 4/5, and 5/5 unit sheets. However, if there is a shortage (missing page), the pass / fail determination means 12 determines NO. At that time, the range determination means 13 determines NO for all unit sheets of the booklet, that is, all unit sheets of the same booklet serial number.

  Further, the range affected by the determination is, for example, determined as “no” for all unit sheets that are pasted and not collated within a predetermined time. In other words, it is assumed that the setting is made to stop the operation of the collating machine when the pass / fail determination means 12 determines NO. At that time, the unit papers 101d to 101g (see FIG. 1) that have been glued cannot be collated within an appropriate time. Therefore, even if the operation is resumed, the glue is dried and becomes a poorly collated product. Therefore, when the pass / fail determination unit 12 determines that the unit sheet 101g is not accepted and the operation is stopped and a predetermined time has elapsed, the range determination unit 13 determines that all the unit sheets 101d to 101g are rejected.

  The bookbinding history generation unit 14 generates a bookbinding history in which the unit sheet is associated with the determination when the quality determination unit 12 determines that the unit is good. Further, when the pass / fail judgment unit 12 determines NO, a bookbinding history is generated in which the unit sheet determined to be NO by the range determination unit 14 is associated with the determination. The bookbinding history is, for example, data in the form of a table (relation) having at least three of “booklet serial number”, “(sheet number) / (total number of sheets)”, and “determination” as attribute values. For example, for (booklet serial number, (sheet number) / (total number of sheets), determination), (100, 8/8, good), (101, 1/5, No), (101, 2 / 5, No), (101, 3/5, No), (101, 4/5, No), (101, 5/5, No), (102, 1/7, Good), ... A bookbinding history like this is generated.

The bookbinding history storage unit 15 stores the bookbinding history generated by the bookbinding history generation unit 14. The stored bookbinding history is data for quality control and production management, and serves as basic data when a booklet that has not been normally produced is reproduced. That is, the booklet of “booklet serial number” whose bookbinding history determination is “No” is reproduced.
The display unit 16 displays the bookbinding history generated by the bookbinding history generation unit 14. The collation process operator can monitor the collation state on the display screen of the display means 16. The display means 16 is also a GUI (graphical user interface) when the operator operates the collation inspection PC 10.
The printing unit 17 prints the bookbinding history generated by the bookbinding history generation unit 14. The operator of the collation process can accurately deal with the collation state using the printed matter output by the printing means 17.

The configuration has been described above. Next, the operation in the collation inspection system of the present invention will be described with reference to the drawings. FIG. 4 is a flowchart showing the process of collation inspection. FIG. 5 is a flowchart showing the contents of step S7 (data processing) of the collation inspection process.
First, in step S1 (product information reading) in FIG. 4, product information to be collated from a production management system (not shown) or the like is read into the collation inspection PC 10 via a network or the like. Then, the collation inspection PC 10 is set to the collation inspection mode.
Next, in step S2 (continuous paper supply), the continuous paper 100 to be collated is set in the paper supply unit 30, and the operation of the collating machine is started.

Next, in step S3 (paper cutting), the paper supply unit 30 cuts (cuts) the paper with a cutter provided therein and supplies the continuous paper 100 as unit papers 101a to 101h to the paper transport unit 40.
Next, in step S4 (unit paper conveyance), the paper conveyance unit 40 conveys the unit papers 101a to 101h in a state where the sheets are separated and arranged one by one.
Next, in step S5 (glue coating), the glue coating unit 50 applies glue to the unit sheets 101a to 101h that have been transported there.

Next, in step S6 (print code reading), the barcode reading unit 20 reads the print code printed on the unit sheets 101a to 101h.
Next, in step S7 (data processing), the collation inspection PC 10 performs data processing based on the product information included in the print code read by the barcode reading unit 20. The process will be described with reference to FIG.
First, in step S101 (quality determination) of FIG. 5, the quality determination means 12 of the collation inspection PC 10 includes at least the product information including the booklet serial number, the total number of sheets, and the number of sheets in the print code read by the barcode reading unit 20. The product information stored in the corresponding product information storage means 11 is compared to determine whether it is good (match) or not (mismatch).

Next, in step S102 (good?), The process proceeds to step S104 when the determination of the quality determination means 12 is “good”, and to step S103 when the determination is “no”.
Next, in step S103 (range determination), the range determination unit 13 determines that there is no unit sheet in the range affected by the determination together with the unit sheet.
Next, in step S104 (bookbinding history generation), the bookbinding history generation unit 14 associates the unit sheet read by the barcode reading unit 20 with the determination when the quality determination unit 12 determines that the determination is good. When the means is determined to be NO, a bookbinding history is generated in which the unit sheet determined to be NO by the range determining means 13 is associated with the determination.

Next, in step S105 (bookbinding history storage), the bookbinding history storage unit 15 stores the bookbinding history generated by the bookbinding history generation unit 14.
Next, in step S106 (bookbinding history display), the display unit 16 displays the bookbinding history generated by the bookbinding history generation unit 14.
Next, in step S107 (bookbinding history printing), the printing unit 17 prints the bookbinding history generated by the bookbinding history generation unit 14.

  Next, in step S8 of FIG. 4 (operation based on determination), some processing based on determination is performed. For example, when it is determined as “No”, the collation inspection PC 10 outputs a command to the collation machine such as sounding an alarm or stopping the operation. Further, based on the determination, the operator takes measures so that damage due to the malfunction is minimized. Then, if necessary, after returning to any of the steps described above, the steps after that step are resumed. Needless to say, if “good” is determined, nothing can be done in step S8 and the process can proceed to the next step.

Next, in step S9 (collation), the collation unit 60 collates unit sheets to obtain a booklet. When the collation unit 60 collates all the unit sheets having the same booklet serial number, the collation unit 60 supplies the booklet to the press unit 70.
Next, in step S10 (press), the press unit 70 pressurizes the booklet on the press surface to ensure that the collated booklet is glued. It also improves the flatness of the booklet.
Next, in step S11 (stack), the stack unit 70 stacks the booklets sent from the press unit 70.

  The series of processes in the collation inspection described above is a process performed for each unit sheet and a booklet that collates it. As shown in FIG. 1, each part in the collating machine operates independently and in parallel. Therefore, the unit paper is glued, the unit paper is scanned, the print code is read, the unit paper is processed for collation inspection, the unit paper is collated, Some things with a booklet are pressed, others with a booklet are stacked, and so on.
