Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention almost completely prevents duplicated or missing printed matter, defective printing, incorrect delivery of printed matter, and the like.
The present invention relates to a print system that sequentially prints different print contents at high speed to create a desired print product, and a print result management device related to such a print system.

[0002]

2. Description of the Related Art A method of recording predetermined information on a medium such as paper in a visually recognizable manner is to record the same information on a large amount of medium at high speed by a printing machine using a printing plate. Also, a method of printing arbitrary data on a relatively small number of media at a low speed by a printer used as a terminal device of a computer is well known.
However, there is also a demand for printing a large amount of variable data, that is, different data for each sheet at high speed, and a high-speed printer device for that purpose has been put into practical use.

Such a printer device for printing variable data at a high speed has a conveying means for conveying a print medium at a high speed, a printing means for recording an image on a sheet conveyed by the conveying means at a high speed, and a sequentially input printing. It is composed of a control unit or the like that appropriately controls data so that it is appropriately printed on paper. As the printing means, for example, a method of printing by an inkjet method with an inkjet head is applied. As such a high-speed printer apparatus for performing printing by the inkjet method, for example, an apparatus for performing printing at a speed of 5 m / sec and 15 or more sheets / second for A4 size printing paper has been put into practical use.

Further, as one of the objects to which such a high speed printer is applied, for example, stock certificates, various cash vouchers, or a large number of bills to a large number of customers, the printing amount is large and different numbers are used. There is printing of documents that must be printed or the contents. When printing such important documents, it is necessary to completely prevent defects such as duplication and dropout of printed contents, defective printing such as scraping and crushing, and low variations such as line width and shading variations. Quality printing is not allowed, and accurate data must be printed in high quality. Further, when printing important documents such as bills and cash vouchers, it is required to print a desired amount of a desired document, that is, to create only one printed matter having one content. We must avoid omissions altogether.

[0005]

However, when printing such an important document with the high-speed printer as described above, it is very difficult to meet the various printing conditions as described above. There is. For example, when printing an important document as described above in such a high-speed printer, it is necessary to completely eliminate defective printing, and there is a desire to inspect individual prints for that purpose. However, it is naturally impossible to visually inspect a printed matter printed at a speed of 10 sheets or more per second in real time, and even if the individual printed matter is inspected after being printed, a huge number of workers and enormous amounts are required. It takes time, and it is almost impossible for a human to visually inspect the printed matter one after another. Therefore, there is a problem that the printed matter cannot be sufficiently inspected and the possibility of shipping defective printed matter cannot be eliminated.

Further, when printing such an important document, duplication or omission of printed matter is not allowed, and one printed matter in which desired print contents are appropriately printed must be created. However, due to the high speed in the high-speed printer device as described above, there is a possibility that printing may be lost, and in addition, when defective printing occurs or when the printing process is stopped midway, it may be discarded. It can be easily imagined that an error occurs such that the printed matter which is being processed is duplicated or missing. That is, it has been difficult for the current high-speed printer device as described above to create such a printed matter so as not to include such a duplication, omission, or defective printing of one sheet.

Therefore, it is an object of the present invention to perform a fine inspection of the print results of individual printed matters, thereby eliminating defective printed matters and performing accurate and high-quality printing, and further, to prevent overlapping and omission of printed portions. It is to provide a reliable printing system that can be completely avoided.

[0008]

In order to solve the above problems, an inspection device capable of accurately inspecting a print result is provided, and when a defect is detected, a mark is immediately applied to a printed matter so that the inspection result is effective. To use. In addition, printed matter to be printed, properly printed matter, poorly printed matter, printed matter output to the outside as properly printed matter, and discarded printed matter,
Centralized and unified management is carried out in a dedicated management device to prevent duplication and omission of printed materials.

Therefore, the printing system of the present invention includes a printer device that sequentially prints different print contents at high speed, and a print result that inspects the print state of each print product and determines whether the print is appropriate or not. Inspecting device, marking device that prints a mark indicating that the printed product is determined to be improperly printed, defective printed material removing device that excludes the printed material with the mark, and the results of those inspections and And a management device that manages the processing state of each printed material based on the data of the excluded printed material. With the management, it is confirmed that the printed matter whose print state is determined to be appropriate is certainly output without being rejected as a defective printed matter, or the printed matter whose print state is determined to be inappropriate is reliably determined as a defective printed matter. This is a process for confirming that it has been excluded. Specifically, with respect to the list of print objects to be processed stored in the management device,
This is a process of setting a flag indicating that these processes have been confirmed. With such management information, it is possible to easily detect erroneous output of defective printed matter, erroneous disposal of normal printed matter, and other inconsistencies in various processes.

Further, in this type of printed matter, print data for each printed matter and a destination to which the printed matter is sent are often printed as print contents such as a bill. For such a printed matter, a system including a printed matter enclosing device that automatically encloses the printed result in an envelope is suitable. In such a system according to the present invention, a printed matter is appropriately sealed in the envelope by further providing a sent matter inspection device and inspecting the destination of the envelope after the printed matter is sealed in the envelope. Whether or not it is, and the final check of the printed matter itself is performed. At this time, the management device determines that the printed matter is properly output, that is, manages, when the sent matter inspection device determines that an appropriate sent matter is formed.

Further, in the case of printing a printed matter having such a destination, the marking device fills the printed destination of the printed matter with respect to the printed matter determined to be improperly printed. It is preferable to perform such marking. By doing so, even if all the inspections are passed and the defective printed matter is output to the outside, it is not possible to send the printed matter, and at least avoid accidental and duplicate shipping. You can In addition, as a defective print mark that is identified by a defective printed material eliminating device or added by the marking device so that it can be visually recognized by an operator, any mark such as a predetermined character, character string, figure, or bar code is used. You may These marks may be marked at arbitrary positions such as a marginal area of the printed matter, but it is desirable to mark them in a predetermined area defined to some extent in order to detect the marks.

Further, as a preferable configuration in the printing system of the present invention, reprinting is performed on the printing object determined to be improperly printed based on the information managed by the management device as described above. Have means. This reprinting means may be the original printer device. However, when it is desired to eliminate defective prints more quickly, that is, to appropriately print all prints and end the printing process, the reprinting unit is a second printer device different from the original printer device.
Specifically, it is desirable that the printer device is, for example, an electrophotographic printer that has a low possibility of defective printing at a low speed.

Further, according to the present invention, a print result management device having the print result inspection means, the marking means, the defective printed material removing means, the second printer device, and the management means, or the convenience of system configuration, or It is also provided in the form of a print result management device including the management means and the second printer device.

Further, the printing method of the head 220 will be described with reference to FIG. FIG. 6 is a diagram for explaining the structure and operating principle of the head 220. Head 220
In, the ink 224 in the ink bottle 221 is dripped from the nozzle 222 corresponding to each dot at a cycle of 100 kHz, that is, 100,000 drops per second. For each of the inks 224, when the position of the printing paper 800 conveyed under the nozzle 222 is a position where black should be printed, the ink 224 is dropped on the printing paper 800 as it is. , The position of the printing paper 800 is blackened. If the position is a blank position that should not be printed, an electric field is applied by an electric field applying unit (not shown) to draw the ink 224 toward the catcher 223. As a result, the ink 224 is transferred to the catcher 22.

By this method, the head 220 is
As shown in FIG. 7, dots having a dot pitch of about 0.1 mm and a dot size of about 0.1 mm in diameter are appropriately printed to print a desired image. It should be noted that in the head 220, it is possible to drop a plurality of inks 224 at the same position, and the printer device 10 thereby expresses pseudo gradation. Further, in the present embodiment, as the inkjet head, SITEX Digital
A 240 dpi / 4 inch inkjet head manufactured by Printing Co. is used.

The head driving unit 230 is the same as the printing unit 2 described above.
00 is a means for finely adjusting the position of the head 220.
In this embodiment, the four heads 220 _{-1 to} 22
Since one printed matter is printed using _0-4 , if these positions are displaced, the positions of the printed dots are also displaced, and proper printing cannot be performed. Therefore, the head drive unit 23
It is necessary to adjust the position of 0 with the same level of accuracy as the resolution of the printer device 10, and the head drive unit 230 performs the position adjustment. Therefore, the head driving unit 230 is
Pieces of composed head 220 _-1 220 four head driving unit corresponding to _-4 230 _-1 to 230 _-4. Each of the head driving units 230 _-i (i = 1 to 4) includes heads 220 _{-1 to} 22

The control unit 600 generates a position adjustment signal for each head 220 _-i (i = 1 to 4) based on the inspection result of the print result in the inspection unit 500 described later. Further, the adjustment of the head 220 is performed both in the main scanning direction that is the direction of the print head (X direction in FIG. 5) and in the sub scanning direction (Y direction in FIG. 5) that is equal to the printing paper transport direction. However, with respect to the adjustment in the Y direction, the adjustment of the position of the head 220 and the adjustment of the print timing in the head 220 are performed together so that appropriate printing can be finally performed.

The print image storage unit 240 includes the print unit 20.
This is a memory for storing image data printed on the printing paper 800 by 0, and a dual port RAM is used in the present embodiment. The print image storage unit 240 stores the image data transferred from the overall control device 50 via the interface unit 250 or the image data generated by the test pattern generation unit 300 in a bitmap format.

The interface section 250 is an interface for transferring the print image data transferred from the overall control device 50 to the print image storage section 240, and is a dedicated serial interface in the present embodiment. The print image data is transferred at high speed by the interface unit 250 according to the print speed.

The test pattern generation unit 300 generates a test pattern for checking whether each unit of the printer device 10 operates normally and can print properly. In the present embodiment, the image data used for the check is stored in advance in the ROM in the test pattern generation unit 300, and the image data is read out based on the control signal input from the control unit 600, and the bit map is read. The image is developed and output to the print image storage unit 240. Note that the control unit 600 causes the test pattern generation unit 300 to generate a test pattern before performing a series of printing operations, such as when the printer device 10 is started up, and performs test printing to determine the printing state of the printer device 10. To check.

In this embodiment, as the test pattern, a first test pattern for adjusting the positions of the four heads 220 _{-1 to} 220 _-4 and a second test pattern for evaluating the state of the print heads are used. And the third test pattern for evaluating the printed character quality are used. FIG. 8 shows a part of the first test pattern for adjusting the position of the head 220 _-i (i = 1 to 4). FIG. 8A is a diagram showing a part of the test pattern,
(B) is an enlarged view of the area C of (A).

Two heads 22 as shown in FIG.
A pattern in which there is a 1-dot gap between 0 _-i and 220 _-i-1 (i = 1 to 3) is printed, and even on the printed image, the gap d becomes a gap of 1 dot. If it is checked whether or not there is a difference in the position between the two heads in the X direction (main scanning direction), correction can be performed. Also, by checking whether or not the patterns printed in the X direction as shown in the test patterns E1 and E2 of FIG. 8B are printed on the same row, the two heads 220 _-i , 220 _-i-1 of the print position in the Y direction (sub-scanning direction) can be detected and correction can be performed.

FIG. 9 shows a second test pattern for inspecting the state of the print head. The second test pattern shown in FIG. 9 is composed of three test patterns F, G, and H. The test pattern F is a pattern in which a straight line is drawn in the X direction for each dot in the Y direction, that is, a pattern in which all dots of each head are alternately printed in black or white. The test pattern G is a pattern in which black or white is alternately printed for each dot in the X direction and a straight line is drawn in the Y direction. The test pattern H is a pattern obtained by inverting the black or white of each dot of the test pattern G. By using such a second test pattern, for example, the function of the head 220 can be inspected for each dot. For example, if there is nozzle clogging, ink leakage, or interference with other dots, it can be detected immediately.

Although not shown, the third test pattern is a test pattern in which many various characters are arranged. Using this third test pattern, the print quality of significant characters and figures is checked. Specifically, it checks for uneven characters, thin characters, thick characters, printing position differences, white spots, pinholes, character skew, stains, density differences, and missing characters.

The image reading unit 400 reads the image printed on the printing paper by the printing unit 200 in order to check the print content and print quality, and the inspection image storage unit 460 as bit map image data.
Output to The image reading unit 400 is shown in FIG.

The encoder 421 rotates integrally with, for example, the printing paper conveyance roller of the paper conveyance unit 110 and outputs a predetermined pulse corresponding to the rotation angle. The pulse is counted by the counter 422, and based on the count value within a predetermined time in the speed calculation unit 423,
The transport speed of the printing paper 800 is calculated.

The light irradiating section 430 is means for giving an appropriate amount of light to the area on the printing paper where the image is taken in by the CCD camera 440 described later. In the present embodiment, the light of the halogen lamp provided in the housing is guided by the fiber cable to irradiate the imaging range of the CCD camera 440. When the CCD camera 440 captures an image, the amount of light required increases as the conveyance speed of the printing paper 800 increases. That is, the printing paper 800
And the required light amount have a substantially proportional relationship. Therefore, the amount of light emitted by the light emitting unit 430 is equal to that of the encoder 4
The control is performed based on the conveyance speed of the printing paper detected in 21.

Next, this inspection is carried out by using the specific test pattern as shown in FIG.
If the inspection is to inspect a specific operation / function of (step S3), the test pattern is searched from the read image data stored in the inspection image storage unit 460, and the print state of the pattern is searched. Is checked (step S4). When the print state is appropriate (step S5), the fact that the operation / function test is good is output (step S12), and the test is finished (step S14). Also, step S5
If the print state is inappropriate, the problem output is output (step S
13). The inspection ends (step S14).

In step S3, if this inspection is an inspection of the printing result during the normal printing operation and the inspection is to perform the overall matching of the print images,
Check the setting whether to perform matching with the compressed image or the original image (step S6),
If the mode is one in which matching is performed using a compressed image, compression is performed in step S7. This compression divides the image into 2x2 or 3x3 pixels, for example,
When the total pixel value of each element is greater than or equal to a predetermined value, the corresponding pixel is set to 1, and the original image is divided into 1/4.
Alternatively, it is compressed to 1/9. Next, matching is performed.
The matching sequentially compares the read image data with the pixels of the original print image data (step S8),
The number of pixels that do not match is accumulated (step S9).
Note that this matching is simultaneously performed for a plurality of pixels. For example, if the image data is binary data and the microprocessor is a 32-bit CPU, matching is performed on 32 pixels at the same time.

If the cumulative number of mismatched pixels is larger than the predetermined threshold value THL (step S
10) It is determined that the image data read from the printed matter is different from the original print image data, that is, there is a problem in the print content or print quality. Then, a signal indicating that the print result is defective is output (step S1).
3), the inspection is completed (step S14). When the accumulated number of non-matching pixels does not exceed the threshold value THL (step S10) and the matching is completed for all the pixels in the matching target area (step S11), a signal indicating that the print result is normal is output ( In step S12), the inspection ends (step S14).

By such an operation, the inspection unit 500 causes the print image storage unit 240 and the inspection image storage unit 46.
The image data stored in 0 is compared. The inspection result is output to the control unit 600.

The control section 600 is a control section for controlling each section of the printer device 10 to perform a desired operation. Printing conditions and control conditions are input to the control unit 600 from the overall control device 50 via the Ethernet I / F in the control unit 600. Based on the input data, the control unit 600 controls the paper conveyance unit 110, the printing unit 200, the image reading unit 400, and the heater 62 described later.
The operating condition such as 0 is set, and the control is performed so that the conveyance of the printing paper, the printing on the printing paper, and the reading of the printed image can be performed synchronously and appropriately.

The control section 600 also inspects the operation of the printer device 10 automatically or according to an operator's instruction prior to a series of printing operations. Further, the head drive unit 230 is controlled so as to correct the position of the head 220 of the printing unit 200 based on the inspection result. further,
When a signal indicating defective printing is input from the inspection unit 500 during the printing operation, the control unit 600 performs the defective printing so that the defective printing marking unit 630 performs printing such that the printed matter is invalidated. The print marking unit 630 is controlled.

The defective print marking section 630 is the inspection section 5.
When it is determined in 00 that the print result is a defective print, a mark that invalidates the print content is printed on the print. The defective printing marking portion 630 is
As shown in FIG. 3, it has a fill print head 631 that is a first print head, a defective print mark print head 632 that is a second print head, and a print control unit (not shown). Based on the input signal, the print control unit controls each head to print a desired image at a desired position.

The fill print head 631 is a head for printing a predetermined fill pattern on a predetermined area of the printed matter, whereby the content already printed on the area is made unidentifiable. At first glance, it turns out to be a defective product, so that it can no longer be used as the original product. Specifically, for example, when the print target is an invoice with an address, the address part is filled in so that the defectively printed invoice is not actually sent, and the print target is various securities or In the case of a cash voucher, for example, the amount part and the number part of the voucher are painted out so that it is apparently unusable. The defective print mark print head 632 prints a predetermined mark on a predetermined area of the defective print by passing it through an inspection device and by a printing operator or the like so that the printed matter can be recognized as a defective print. To do. In the present embodiment,
An alphanumeric error code indicating the detected defect type is printed in the blank area at the lower right of the printed matter.

The fill print head 631 and the defective print mark print head 632 have the same configuration and printing method as the head 220 of the printing unit 200, and each have a print width of 1
It is an inch inkjet head. Further, these heads can be moved to arbitrary positions in the main scanning direction (direction perpendicular to the paper feeding direction). Therefore, based on the printing paper and the printing format, by moving these heads in advance to the area where the fill pattern or the defective print mark is to be printed, it is possible to print those patterns at any position on the printing paper. it can. In addition,
The exact print position in the print area of each head is controlled by the print control unit in the defective print marking unit 630. In addition, the print control unit detects the position of each printed material based on the output of a cue mark detection sensor (not shown) and an encoder, which are provided in the vicinity of each of the heads, and detects the position of each printed material. Determine the exact print position in the paper feed direction).

The operation unit 610 is an operation terminal for performing relatively simple operations such as setting work conditions and print parameters on the printer device 10 and notifying the operator of the data notified from the printer device 10. is there. In this embodiment, a general-purpose personal computer is used as an RS.
It is used by connecting with a 232C interface.
The operation unit 610 also outputs a log file of the inspection result of the printing state and the like.

The heater 620 is a blower of warm air for drying the ink on the printed printing paper 800, which is provided after the defective printing marking portion 630 of the printer device 10.

Next, the operation of the printer device 10 will be described with reference to FIGS. 15 and 16. FIG. 15 is a diagram showing a state in which print data is printed on the printing paper 800 which is continuous paper in the printer device 10.
FIG. 6 is a diagram showing a state in which a mark is printed on the first page. 15 and 16, the printing paper 800
Is a bill such as a telephone charge, and a billing destination address 801, billing destination information 802, and bill details 803 _{-1 to} 803 _-3 over three pages are printed. A cue mark 804 is printed on the upper right of the first page of each bill. With this cue mark, it is possible to know the delimiter position of each invoice from the continuous paper. Hereinafter, such a bill will be issued to the printer device 1.
The operation of the printer device 10 when printing with 0 will be described.

First, before the actual printing process, the print pattern and print quality are inspected using the above-mentioned test patterns generated by the test pattern generation unit 300. As a result of the inspection, when it is confirmed that the printer device 10 operates normally, print contents, print conditions, etc. are input via the operation unit 610 and the host computer of the upper level,
Each unit of the printer device 10 is initialized based on the input information. At this time, for example, the type of fill pattern, the filled area, the type of defective print mark, the printing position of the defective print mark, and the like performed by the defective print marking unit 630 are also set.

When the initial setting is completed, the bitmap image data to be sequentially printed is input through the interface unit 250, stored in the print image storage unit 240, and then printed on the printing paper 800 by the printing unit 200. The image printed on the printing paper 800 is read by the image reading unit 400 and stored in the inspection image storage unit 460, and the inspection unit 500 compares and collates with the original image data stored in the print image storage unit 240. Then, it is determined whether the two images match. If the two images match, it is assumed that the printing was performed properly, and the printed matter is conveyed as it is,
It is wound up by the winding unit _110-6 .

When a black line 810 as shown in FIG. 16 is generated in the image printed by the printing unit 200 during the sequential execution of the printing process, the image reading unit 400 reads the inspection image. The image stored in the storage unit 460 and the print image storage unit 2
The original image data stored in 40 does not match because of this black line 810. As a result, the inspection unit 500 detects that the print state is bad. The control unit 600, to which the signal indicating that the print state is defective is input from the inspection unit 500, immediately fills the defective print marking unit 630 in a predetermined area of the invoice and an error indicating the detected defective state. Output the signal to print the code.

As a result, the filling print head 631
Fills the area 821 with black so that the contents below cannot be seen. Further, the defective print mark print head 632 of the defective print marking unit 630 records an error code 822 in the lower right area of the printing paper. The invoice with these patterns and error codes printed thereon is also sequentially wound into the winding unit 110 _{-6 in the} same manner as the invoice normally printed.
It is wound up. Further, the result of the inspection of each bill in the inspection unit 500 is the control unit 600 and the I / F unit
It is output to the inspection management device 30 via 50. In this way, in the printer device 10, the bill is printed continuously on the continuous paper.

Next, the structure and operation of the sealing device 20 will be described with reference to FIG. FIG. 17 shows the encapsulation device 2
FIG. 3 is a block diagram showing a configuration of a 0. The encapsulation device 20 includes a printed matter supply unit 900, a burster 910, and a printed matter selection unit 9
20, an inserter 930, a delivery inspection unit 940, and a stacker 950. The printed matter supply unit 900 includes a printing sheet 800b on which printing is performed by the printer device 10.
Is set, and the printed matter printed on the continuous paper is sequentially supplied to the enclosing device 20. The printing paper 800b, which is printed by the printer device 10 and sequentially wound, is automatically set in the enclosing device 20 for each roll by an automatic transport device (not shown). The printed printing paper 800b set in the printed material supply unit 900 is sequentially unwound by a paper conveyance unit (not shown), passes under the camera 921 of the printed material selection unit 920, and is supplied to the burster 910. It

The bar star 910 cuts the printed matter supplied in the form of the printing paper 800b into each printed matter. The burster 910 detects a cue mark printed on the print sheet 800b by a cue mark detection sensor (not shown), and sequentially cuts the print sheet 800b at the cue mark. For example, in the case of the printing paper shown in FIG. 15, cue mark 804 _-1, respectively the printing paper is cut at a point 804 _-2. As a result, the printed matter printed by the printer device 10 is divided for each bill. The cut-off printed matter is placed in the enclosing device 2 in the same manner as the cut sheet is conveyed.
It is transported through 0.

The printed matter selection unit 920 distinguishes printed matter that is properly printed and improperly printed matter from the sequentially supplied printed matter, and eliminates improperly printed matter.
Select only prints that are suitable for printing. Printed matter selection unit 92
0 is a camera 921, a pattern memory 922, an identification unit 92.
3, a control unit 924 and a printed matter selection unit 925.
The camera 921 is an image reading device for detecting a defective print mark marked by the defective print marking unit 630 of the printer device 10. Camera 9
Controlled by the control unit 924, the reference numeral 21 fetches the image data of the area in which the above-mentioned error code is printed from the printed matter sequentially conveyed in the field of view, and outputs it to the pattern memory 922. The camera 921 has the same configuration as the CCD camera 440 used in the image reading unit 400 of the printer device 10. Positioning of the area in which the error code is printed in the sub-scanning direction (paper feed direction) is performed by a cue mark detection sensor and an encoder (not shown) provided near the camera 921.

The pattern memory 922 stores the image of the defective print mark print area of each print input from the camera 921. The identification unit 923 identifies the content printed in the defective print mark print area of each print stored in the pattern memory 922. In the present embodiment, the same pattern as the pattern of the defective print mark printed by the defective print marking unit 630 of the printer device 10 is stored in the memory in the identifying unit 923, and the identifying unit 923 is stored.
In, the contents of the pattern memory 922 are identified by performing template matching between the pattern of this memory and the pattern stored in the pattern memory 922. Therefore, the identification unit 923 detects whether or not the defective print mark is printed on each printed matter and, if printed, the type of the defective print mark, and outputs the detected print mark to the control unit 924.

Based on the identification result from the identification unit 923, the control unit 924 sends the printed matter conveyed to the printed matter selection unit 925 as the normal printed matter to the inserter 930.
A signal for selecting whether to output to the printer or to reject as a defective print is output. The control unit 924 also controls the camera 921.
And the output of the identification result to the inspection management device 30. The printed matter selection unit 925 switches the conveyance path of the printed matter based on the selection signal from the control unit 924, and selects the printed matter that is divided and conveyed in the burster 910 as the printed matter that is output to the inserter 930 as it is and the printed matter that is excluded. To select. The rejected printed matter is stored in the rejected sheet stacker in the printed matter selection unit 925.

The inserter 930 appropriately folds the printed matter sequentially conveyed, inserts it into each envelope, and seals it. In the present embodiment, the envelope into which the printed matter is inserted has a window formed of transparent vinyl, and the destination is visible from the outside through the window. Therefore, each printed matter is inserted into the envelope so that the column where the printed matter is printed can be confirmed from this window.
In other words, each printed matter has a destination and a management number printed in an area visible through a window provided in the envelope when the envelope is inserted.

The sent item inspection unit 940 uses the inserter 930.
For each envelope conveyed further, it is checked whether or not the printed matter is properly inserted, and which printed matter is properly inserted. The sent item inspection unit 940 performs the above-mentioned inspection by reading a control number that can be confirmed from the window through the window provided in the envelope. That is,
If the control number can be properly read when the control number is read through the window, it is considered that the printed matter is properly inserted, and the printed matter is specified based on the control number. If the control number cannot be read, it is determined that the insertion state of the printed matter is not appropriate, and if the area where the control number should be printed is filled,
It is determined that defective prints are mixed.

The sent item inspection section 940 has a camera 941, a pattern memory 942, an identification section 943 and a control section 944. Each of these components has substantially the same function as the corresponding component of the printed matter selection unit 920. Camera 941
Is an image of a predetermined area of the envelope in which the printed matter to be conveyed is enclosed, specifically, an area corresponding to the transparent window of the envelope, including the area in which the control number is printed. Read the image of the area. Camera 92
1 controls the control unit 944 to fetch image data of a desired area from each envelope sequentially transported in the field of view, and outputs the image data to the pattern memory 942. This camera 941 also has the same configuration as the CCD camera 440 used in the image reading unit 400 of the printer device 10. Positioning of the reading area in the sub-scanning direction (paper feed direction) is performed based on signals from an edge detection sensor and an encoder (not shown) provided near the camera 941.

The pattern memory 942 stores the image input from the camera 941. The identification unit 943 identifies the management number from the image stored in the pattern memory 942. In the present embodiment, the same pattern as the pattern of the management number printed in the printer device 10 is stored in the memory in the identification unit 924, and the stored pattern and the pattern stored in the pattern memory 942 are stored. By matching and, the pattern memory 94
Identify the contents of 2. Therefore, from the identification unit 943,
If the management number can be identified, if the number cannot be identified, information indicating whether or not the paint pattern has been printed in the area is output.

The control unit 944 outputs the identification result from the identification unit 943 to the inspection management apparatus 30. Shipment inspection section 94
It is basically rare to find an abnormal printed matter at 0, and the main function is to check the normal control number. Therefore, here, even when an abnormality is found, the handling of the envelope is not particularly changed, and only the information is output to the inspection management device 30. The control unit 944 also controls the camera 921.
Also controls.

The stacker 950 stores and accommodates each printed matter inserted into the envelope and ready to be sent by the enclosing device 20.

Next, the structure and function of the inspection management apparatus 30 will be described with reference to FIG. The inspection management device 30 is configured by a general-purpose arithmetic processing device such as an ordinary personal computer device, and appropriately prints based on the data regarding the printed matter input from the overall control unit 50, the printer device 10, and the enclosing device 20. Inspect and manage the printed materials so that they will be properly inserted into the envelope and that the shipment will be created without duplication and omission.

First, to the inspection management apparatus 30, a list of printed matter to be printed, that is, a management number of the printed matter to be printed is input from the overall control unit 50. After that, the inspection management apparatus 30 manages each print object managed by this management number so that it is printed in an appropriate state and is appropriately created as a delivery. When printing of each print target managed by these management numbers is started by the printer device 10,
The inspection unit 500 of the printer device 10 is used for the print result.
The result of the inspection performed in 1 is input to the inspection management device 30. The inspection management device 30 stores the inspection result, that is, whether the printing is appropriate or not, or the error code or the like when printing is inappropriate, for each management number.

When the encapsulation device 20 starts to insert the printed matter that has been printed by the printer device 10 into the envelope, two check results performed by the printed matter selection unit 920 and the sent product inspection unit 940 of the encapsulation device 20 are obtained. It is input to the inspection management device 30. From the printed matter selection unit 920, information indicating detection of a defective print mark for each printing target and whether the printed matter is eliminated or sent to a subsequent process based on the detection is input. The inspection management device 30 records the information in association with the management number and compares it with the inspection result already input from the printer device 10 to ensure that the properly printed printed matter is sent to the inserter 930. Check that the defective printed matter has been reliably removed. When these two inspection results are inconsistent with each other or when the inconsistencies are continuous, a cause investigation and printing stop processing are performed.

Further, the sent product inspection unit 940 inputs the final inspection result of the individual printed products inserted in the envelope. Normally, as the inspection result, the management number of the printed matter that has been properly processed is input, so that the inspection management apparatus 30 terminates the processing of the printed matter of that management number, erases the management data, and substantially erases the management data. Exclude from management. In addition, the sent inspection section 9
When the detection of the defective printed matter is input from 40, the presence of the defective printed matter is notified, and the information that enables the defective printed matter to be taken out from the stacker 950 is output to the overall control unit 50. Further, on the basis of the inspection result for each printed matter stored in the inspection management device 30, processing such as identification of the printed matter and investigation of the cause of defective printing is performed, and if such defective printed matter is detected continuously, It also stops printing.

For example, when a series of printings such as a printing process on one roll of paper is completed, the inspection management apparatus 30 manages the printed matter which has been excluded due to defective printing and the final printed matter has not been generated, that is, the management target. Printed matters with data remaining are extracted, and those printed matters are reprinted by the reprint printer 40. At this time, since the print image data necessary for printing is stored in the overall control unit 50, the inspection management apparatus 30 reads the data of the print content from the overall control unit 50 and outputs it to the reprint printer 40. The inspection management device 30 includes the sent item inspection unit 9
When a printed matter to be managed is exhausted by a signal input from the device 40 indicating that the processing is properly finished, or the printed matter resulting from the reprinting is put into the encapsulation device 20 and the series of processing is completed. When it does, the process is terminated.

Next, the reprint printer 40 will be described. The reprint printer 40 is a printer for reprinting a printed matter that has become defective in the printer device 10. Therefore, a printer device is used that can reliably print even if the printing speed is somewhat slow. In this embodiment, an electrophotographic laser beam printer using a laser is used. The printed matter printed by the reprint printer 40 is also
The printed matter printed by the printer device 10 is placed in the encapsulation device 20.

Finally, the overall control device 50 will be described. The overall control unit 50 is a host computer that controls the entire printing system 1. For example, the overall control unit 50
Is externally input with information indicating the print content to be printed on each printed matter, and based on the information, generates a print image printable in the printer device 10, and the printer device 1
Output to 0. Further, the overall control device 50 uses the printing system 1 based on the print state / inspection result of the printed matter managed by the inspection management apparatus 30 when, for example, the occurrence of defective printed matter is significant or continuous. Perform processing such as stopping the whole.

To summarize the operation of the printing system 1 described above, first, in the printer device 10, different data for each printed matter is sequentially printed at high speed, and the printed image is photographed by the camera to determine the printing state. Check the print contents. When defective printing is found as a result of the printing, a mark is printed on the printed matter. This mark is classified into two types: a mark indicating a normal defective print and a mark that fills an important item of the printed matter. When the printing is completed, the printed matter is set in the enclosing device 20, where the continuous paper is sequentially cut and separated into one printed matter. Then, the defective printing mark printed by the printer device 10 is checked, and the printed matter on which the mark is printed is immediately discarded. The printed matter without the mark printed is enclosed in an envelope so that it can be sent, and at that time, a final check is performed. That is, it is checked whether the address of the printed matter can be seen in the transparent window of the envelope.

During these processes, the inspection management device 30 displays the list of print objects input from the overall control device 50, the inspection result for the printing performed by the printer device 10, and the first inspection performed by the enclosing device 20. The selection result, the check result of the final printed matter, and the like are sequentially input. By associating these with each other, defective prints can be reliably discarded, normal prints can be properly inserted into the envelope for output, and there is no abnormal state or contradiction between these processes. Are always checked. Further, the printed matter discarded as the defective printed matter is always reprinted by the reprinting printer 40, and again inserted into the envelope in the enclosing device 20 to generate an appropriate sent article.

As described above, in the printing system 1 of this embodiment, a large amount of printed matter can be printed at high speed. The printed matter is automatically inserted into the envelope and is ready to be sent. Therefore, when there is a large amount of printed matter such as a bill that needs to print different data, the printed matter can be efficiently created and shipped. In addition, the printed matter is immediately inspected and the printing state is checked, and the state of the printed matter (whether it has been discarded or has proceeded to a subsequent process as a valid printed matter) is always grasped during the processing, and the printed matter is further printed on the envelope. Has undergone a final check after being inserted. Therefore, it is possible to almost completely prevent the defective printing from being output to the outside and the printed matter from being missing or overlapping.

In the unlikely event that a defective printed matter is mixed with a normal printed matter and goes out, in the printing system 1 of the present embodiment, such a defective printed matter will be printed. The important items are filled in. Therefore, the defective printed matter can no longer be used for its original purpose, and accidents such as misdelivery of a bill can be completely prevented. Further, since the printed matter that could not be properly processed is separately printed by the second printer device which is low in speed and has little defective printing, it is possible to appropriately and efficiently deal with such defective printed matter. After all, a large amount of printed matter can be efficiently and accurately created.

That is, it is possible to perform high-speed printing while inspecting the print content and the print state, it is possible to almost completely avoid troubles such as duplication and dropout of the print content, and high reliability of important documents. Can be printed with. Also, if defective printing occurs,
Since the printing process can be stopped immediately, defective printed matter can be minimized. Furthermore, not only the print head itself is defective, but also the print content and print quality can be comprehensively inspected, such as the conveyance status of the print paper and stains due to a defective gap adjustment between the print paper and print head. Can print.

The present invention is not limited to this embodiment, and various modifications can be made. For example, the print medium is not limited to the continuous paper as shown in the present embodiment, but may be cut paper. In that case, the roll paper supply unit 110 _-1 of the paper transport unit 110 may be used as a hopper unit to supply the cut paper. In each unit of the roll paper supply unit 110 _-1 , an edge detector may be provided. It may be provided and positioned in the sub-scanning direction. Of course, the print medium may be a print medium made of a material other than paper, and the handling mechanism of the print medium may have an arbitrary configuration according to the print medium.

The defective print marking portion 630 does not have to include both the fill print head 631 and the defective print mark print head 632, and may be configured to have only one of them.
In addition, the mark for displaying the defective print printed by the defective print mark print head 632 is not limited to the error code as shown in FIG. For example, in FIG.
It is possible to clearly indicate that the printed matter is a defective printed matter by an arbitrary figure as shown in FIG.
As shown in FIG. 8 (B), it may be possible to mark whether or not the explanatory note is valid with respect to the explanatory note clearly indicating that the printed matter is not effective. Alternatively, a barcode or the like may be used.

Further, the filling print head 631 and the defective print mark print head 632 of the defective print marking portion 630 are not limited to the ink jet type heads, but may be any type of heads. Further, in the printed matter selection unit 920, the error code 822 printed on the printing paper 800 is detected and the defective printed matter is selected. However, the filled pattern which is also the defective print mark is detected and the printed matter is selected. You may

In the printing system 1 of the present embodiment, the overall control device 50 controls the entire device, and the inspection management device 30 manages the printed matter. However, these two control devices and management device are both realized by a computer device, and one computer device may be configured to substantially integrate them. Further, the printer device 10 is a monochrome 2
It is not limited to printer devices that print in colors,
It is also applicable to a printer device that performs multi-value printing, multi-color printing, full-color printing, or the like. Other,
The detailed configurations of the printer device 10 and the enclosing device 20, the inspection method for defective printing in the inspection unit 500, etc. are not limited to those in the present embodiment, and may have any configurations.

[0088]

According to the present invention, it is possible to almost completely prevent defective printed matter, duplicated data, missing data, etc. from occurring on printed matter having different contents such as invoices and serial numbers. It is possible to provide a highly reliable printing system capable of high-quality printing.
