Abstract

PURPOSE:To judge whether codes for identification such as the bar codes, etc., of respective slips such as collated slips, etc., are completely coincident with set values or not. CONSTITUTION:A code reader 14 reads the bar codes previously printed on plural rolled paper sheets R1, R2 and R3 to be collated. Thus, the numerical values of the plural bar codes are read. On the other hand, general character numbers (1, 2 and 3, etc.,) are printed by a typographic printer 4 in the state of overlapping the plural rolled paper sheets R1, R2 and R3. Then, an arithmetic judging device 24 executes subtraction between the numerical values of the plural bar codes and the numerical values of the general character numbers (1, 2 and 3, etc.,) and when this subtracted result is coincident with a value set in advance, it is judged that collation is exactly executed. When the result is not coincident with the set value, it is judged that collation is not exact.

2. Description of the Related Art For example, a trader who delivers a parcel or the like to a home attaches a slip D as shown in FIG. 8 to the parcel or the like.
This slip D is composed of, for example, three forms 71, 72, 73. The same machine identification barcode number B is printed on each of the forms 71, 72, 73, and below each barcode B. The corresponding first general character number I for visual confirmation is printed. Further, on the right side of the barcode number B, a second general character number M for visual confirmation corresponding to the barcode number B is printed. FIG. 11 shows a typeface generally used as the second general character number M. Needless to say, fonts and sizes other than those shown in FIG. 11 may be used.

As shown in FIG. 9, the bar code is 2
It consists of black and white parallel bars with different widths, and the start code and end code shown in English letters are printed on both ends, and the bars showing the numerical values are printed in parallel inside them. Each number is represented by four black bars of two types of thickness and three white bars that form a gap therebetween, and a pattern peculiar to each number is formed by the thickness of the bars and how they are arranged. A representative example of the pattern is shown in FIG.

In order to manufacture the slip D, first, a bar code number B and a first general character number I are printed on a continuous form (roll paper). That is, for example, offset
When using a form rotary press, add a letterpress printing section to the offset printing section, attach a bar code numbering machine to this letterpress printing section, and increase the numerical value of each letter ring of this bar code numbering machine by "1" or By decreasing the number of rotations, continuous (for example, 1, 2, 3,
(4, ...) and "Bar code number B" and "first general character number I" are printed.

Next, the roll paper on which the bar code number B and the first general character number I are printed is applied to a collating machine, a plurality of the roll papers are superposed, and the number of the printing unit of the collating machine is overlapped. A plurality of "second general character numbers M" are printed simultaneously by a numbering machine (printing device) attached to the shaft. Here, a plurality of numbering machines are usually attached to one axis on the numbering shaft, and the second general character number M is continuously printed.

The bar code numbers B of the respective forms of the slip D collected in this way must all be the same, and the bar code number B / first general character number and the first number It must match the general character number M of 2.

[0007]

However, due to mechanical troubles of the collator, for example, forms having different numerical bar code numbers may be superposed at the stage of superposing a plurality of roll papers. In addition, due to a malfunction of the number shaft of the printing unit, the second general character number out of the normal order may be printed.

The slip D in the defective collated state cannot be shipped as it is. Therefore, conventionally, an operator visually confirms the matching check between the barcode number / first general character number and the second print general character number.

However, the visual work in accordance with the high printing speed is extremely burdensome to the operator, and also raises the manufacturing cost in terms of labor cost. Furthermore,
Even if a numerical discrepancy occurs due to a malfunction of the numbering shaft or collator, etc., if the discovery is delayed and cannot be processed promptly, printing time, collating time, and printed roll paper will be wasted. It was

Therefore, the object of the present invention is to
It is possible to confirm that the barcode number and the first general character number of each form that compose the slip match. Also, it is possible to confirm that each form and the barcode number and the first general character number and the second general character number match. It is to provide a collation monitoring device for code numbers.

[0011]

In order to solve the above-mentioned problems, according to the present invention, when a plurality of strips are superposed and cut to form a plurality of combination slips, each strip of the combination slips is formed.

(2) Detailed Description of Each Constituent Device Next, in each of the constituent devices, [I] "Bar code number B" and "first general character number I" are read, and [II] "No. The general character number "2" will be described in detail below. [I] Partial barcode reading unit 14 for reading the barcode number B and the first general character number I The configuration and operation of the barcode reading unit 14 will be described with reference to FIG.

As shown in FIG. 2, the laser beam A emitted from the laser output section 31 passes through the lens section 32,
The bar code number B is scanned by being reflected by the rotary polygon mirror 33 that is rotated by the half mirror 35 and the motor 34. Here, the reading speed of the barcode number B is determined by the rotation speed of the motor 34 and the number of surfaces of the rotary polygon mirror 33. For example, when the rotating polygonal mirror 33 having 10 surfaces is rotated by the motor 34 at 50 (rps), 500 times per second.
Scan twice. As a result, 10 bar code numbers B are printed per 1 m on the roll paper conveyed at 2 m / s.
Is read about twice for each bar code number B.

The laser beam A scanned by scanning the bar code number B is reflected again by the rotary polygon mirror 33, passes through the half mirror 35 and the condenser lens 36, and is condensed on the light receiving element 37. The light receiving element 37 outputs an analog signal representing the pattern of the barcode number B.

Photoelectric Switch 15 When the bar code number on the roll paper conveyed in the direction of the arrow is conveyed / reached to the position scanned by the laser beam A, the photoelectric switch 15 catches this arrival. The barcode reading unit 14 is notified as a timing signal. This allows the barcode reading unit 14
Reads the bar code number B while the timing signal is being issued. If the bar code reading unit 14 cannot read the bar code number B during this period, the bar code converting unit is connected to the number inspecting unit which outputs the unreadable signal after the period when the timing signal is issued. Output to.

Bar Code Converter 28 Next, the bar code converter 28 for numerically converting the bar code number into a digital signal based on the analog signal from the light receiving element 37 will be described with reference to FIG. The analog electric signal output from the light receiving element 37 is
The operational amplifier 41 performs current-voltage conversion, and inputs the analog voltage signal to the comparator 42. The comparator 42 outputs the analog voltage signal as a binary digital signal of "1" or "0" based on the slice level set by the slice setting circuit 43 and outputs it. This "1"
The value of means the white part on the barcode number,
A value of "0" means a black band portion on the barcode number. Then, the output time of the digital signal of "1" or "0" changes according to the width of the white band / black band. The time length of the white and black bands is counted by the white band counter 44 and the black band counter 45.

That is, the white band counter 44 receives the output from the comparator 42 and the oscillation pulse output from the oscillator 46 via the AND circuit 47, and counts the number of pulses in the part corresponding to the white band. The black belt counter 45 is the comparator 4
A signal obtained by inverting the output from the inverter 2 by the inverter 54 and the oscillation pulse output from the oscillator 46 are input via the AND circuit 48, and count the number of pulses in the portion corresponding to the black band. The count values of the counters 44 and 45 are fetched by the CPU 50 via the data bus 49.

The operation of the CPU 50 for processing each count value will be described with reference to the flow chart shown in FIG. The output of the comparator 42 is taken into the CPU 50 via the parallel input / output circuit 53, and it is determined whether the output value is "1", that is, whether the white band has been read (step S10).
1). In the case of "1", the white band is being read, and the count value output from the black band counter 45 is input to read the length of the black band immediately before the white band (step S102).
At the same time, in order to clear the read count value, the clear signal is sent through the parallel input / output circuit 53 to the black belt counter 45.
Output to.

On the contrary, when the output of the comparator 42 is not "1", the black band is being read, and the count value of the white band counter 44 which means the length of the white band immediately before the black band is input. (Step S103). At the same time, in order to clear the read count value, a clear signal is output to the white band counter 44 via the parallel input / output circuit 53.

The respective count values of the white band and the black band are compared with a code table (see FIG. 10) built in the ROM 51 and numerically converted (step S104). Next, when the end code is recognized (step S105), the conversion result is output to the data bus 49. The serial input / output circuit 52 outputs the conversion result as serial data to the first or second data.
Alternatively, it is output to the third number checking units 24a, 24b, 24c (step S106).

Number collation judging unit 24 The number collation judging unit 24 is arranged in the number collation judging unit 24 of the bar code number preset by the operator from the computer 25 before the reading of the bar code and the general character number is started. Type / Each reading device 11, 14a-14
Initial data such as the installation interval of c is sent, and further an inspection start command and an inspection end command are sent. When the inspection start command is sent, the first number data B _{1 obtained} by sequentially reading the barcode number from the barcode reading unit 14 and binarizing the barcode number B ₁
To receive. The number matching determination unit 24 has a function of determining whether or not the first number data B ₁ matches the number data M ₁ corresponding to the print character or the like to be originally printed. In this case, the determination is made as follows, for example.

That is, the first number data B ₁ read at the first time is used as a reference value for calculating the number data to be originally printed after the second time. A new reference value is obtained by adding or subtracting "1" to this reference value. This reference value is compared with the _first number data B ₁ sequentially printed as the number data to be originally printed. If there is a difference between the two in the comparison result, it is determined that a barcode different from the barcode to be printed is erroneously printed.

If any kind of check digit is provided in the last digit of the bar code number, the check digit is used to determine whether or not the bar code number is correct. May be. Further, if the bar code reading unit 14 outputs an unreadable signal indicating that the bar code number cannot be read because the bar code number is thin or dirty, it is determined that printing is defective.

As described above, if the number collation judging section 24 has a function of judging whether or not the first number data B ₁ coincides with the bar code data to be originally printed, any one of them is provided. When it is determined that an abnormality has occurred, the barcode number and the type of abnormality are transmitted to the computer 25. The computer 25 performs processing such as outputting the bar code number to the printer 26 or issuing an alarm by the alarm 27 depending on the type of abnormality.

Further, the number collation judging section 24 is provided with a second general character number M printed by the number printing unit 4.
Has a function of determining whether or not it matches the bar code number B and the general character number I to be printed originally. The second number data M ₁ read in the first time is
It is used as a reference value for calculating the number data to be originally printed after the second time, and 1 is sequentially added or subtracted to this. If this value is the number data to be printed originally, and there is a difference between the two, it is determined that the second general character number M is abnormal, and that number is output to the printer 26, or an alarm is issued by the alarm device 27. Emit. When the barcode numbers read by the barcode reading units 14a, 14b, and 14c are overlaid, the barcode reading unit 14a, 14b, and 14c has a function of verifying that the barcodes have the same number. In addition, if the second general character number M has a check digit, the check digit is used to determine whether the character is correct or not, and the quality of the second general character number M such as a thin or missing character. You may decide when there is a problem.

As described above, the number collation judging unit 2
The important function of 4 is the first number data BN (N = 1,2 ...
.) Is collated with the second number data MN (N = 1,2 ...) Transmitted from the character recognition unit 23 to determine whether or not they match. Further, collation of different number data BN (N = 1,2 ...) Of different roll papers,
Judgment is also made. [II] Partial CCD camera 11 for reading the second general character number The CCD camera 11 is attached at a position where the second general character number M (see FIG. 8) can be photographed, and the strobe 1
By making 2 emit light for a short time, the second general character number M on the moving roll paper can be photographed in a stationary state. A rotary encoder 13 is provided as means for deciding the timing at which the strobe 12 emits light to be captured as a still image.
The timing counter 21, which receives the pulse signal of, outputs a strobe light emission command signal when the second general character number on the roll paper reaches the center position of the field of view of the CCD camera 11. The timing counter 21 counts the pulse signal generated by the rotary encoder 13, and if the value initially set by the computer 25 and this count value match, the strobe light emission command signal is sent to the strobe controller 22 via the character recognition unit 23. Give out. In this case, the timing counter 21 can freely set the number of sheets to output the strobe light emission command signal based on the count value of the pulse signal from the rotary encoder. Upon receiving the strobe light emission command signal from the timing counter 21, the character recognition unit 23 adjusts the timing with the camera synchronization signal and outputs the strobe light emission command signal to the strobe controller 22.

When the strobe 12 emits light upon receiving this signal, the CCD camera 11 inputs the second general character number M to the character recognition unit 23 as a still image. The character recognition unit 23 converts the input still image into binarized second number data M ₁ using a general number recognition method such as a pattern matching method or a feature extraction method, and the number matching determination unit 2
Transfer to 4.

(3) Description of Operation Next, the operation of the code number collation monitoring device configured as described above will be described with reference to the flowcharts shown in FIGS. 5 and 6.

As shown in FIGS. 5 and 6, first, the power of the entire apparatus is turned on (step S1), and the character recognition unit 2
3. Reset the number matching determination unit 24, etc. (step S
2) Further, initial setting data is input to the computer 25 (step S3). The computer 25 initializes the reading timing of the general character number to the timing counter 21. Since the reading timing differs depending on the item, it is necessary to reset the item every time the item is changed (step S3a). Next, it is judged whether the general character number by printing is read (step S4), it is judged whether the reading flag is set (step S5), and if the reading flag is not set, the data of the general character number M is stored in the memory. Then, the reading flag is set (step S6). After step S6, continuity check digit C
It is determined whether / D is correct, and if not, the error information is transferred to the computer 25 (step S8) and the memory flag is reset (step S9). A detailed flowchart of step S4 is shown in FIG.

If the general character number M by printing is not read in step S4, if the flag is set in step S5, or if the check digit is correct in step S7, the process proceeds to step S11, and the first bar Determine if you have read the code number (bar code number on top roll). If the first barcode number has been read, steps S12 to S
In step 14, the same processing as step S5 to step S7 is performed. If the first bar code number has not been read in step S11, the process proceeds to step S15,
If the second bar code number (bar code number of the roll paper in the middle) is not read, the same processing as that in steps S5 to S7 is performed in steps S16 to S18. If the second bar code number has been read in step S15, the process proceeds to step S19,
If the third bar code number (bar code number of the bottom roll paper) is read, step S20 to step S
In step 22, the same processing as in steps S5 to S7 is performed. If the third bar code number has not been read in step S19, the process proceeds to step S23. A detailed flowchart of steps S11, S15 and S19 is shown in FIG. 6 (B).

In step S23, it is determined whether or not all the bar code numbers and the general character numbers by printing have been stored in the memory. If the storage has been completed, in step S24 (("first bar code number"-" The second bar code number ") is subtracted, and if it is not a preset value, an alarm is issued and a collation error is output to the printer 26, and when such a state occurs, the collator is stopped. (Step S25), the memory flag is reset (step S26).

In step S24, if the subtraction result of "(first bar code number)-" second bar code number "is the set value, in step S27 (" first bar code number "- "3rd barcode number") is subtracted. If this subtraction result is not the set value, the same processing as the steps S25 and S26 is performed. If the result of the subtraction in step S27 is the set value, the process proceeds to step S28 to perform the subtraction ("general character number of printing"-"first bar code number"). If the result of the subtraction is not the set value, the above step S2
5 and the same process as step S26. If the result of the subtraction in step S28 is the set value, an OK signal indicating that the collation inspection has passed is output to the computer 25 (step S29), the memory flag is reset, and the series of processes is completed (step S30). ..

Here, step S23 to step S29
The operating principle of will be described with reference to FIG. As shown in FIG. 7, three of the roll paper R _1, R _2, pre-printed bar code number Code to _{R 3 B 1, B 2,} B 3 each roll paper · · · R _1, R _2, Bar code reader 1 for R ₃
Read at 4a, 14b, 14c. On the other hand, when printing is performed by the letterpress printing device 4 in a state where the _three roll papers R ₁ , R ₂ and R ₃ are stacked, the three roll papers R ₁ , R ₂ and
The same letters and numbers (for example, 1, 2, ₃ and so on) are printed on R ₃ . The printed numbers and the like are read by the print number reading device 11. The bar codes B ₁ , B ₂ , B _3, ... Of the _three rolls of paper that have been read and the printed numbers are calculated and judged by the number collation judging unit 24 and the computer 25. For example, the difference between the barcode B _{4 of} the bottom roll paper R _{1 and} the barcode B ₇ of the roll paper R ₂ is calculated to calculate the difference b. Similarly, the difference a between the bar code B _{4 of} the bottom roll paper R ₁ and the bar code B ₁₀ of the top roll paper R ₃
Is calculated, and the difference c between the bar code B _{4 of} the bottom roll paper R ₁ and the printed number is calculated. Where the differences a, b, c are
Bar code readers 14a and 14c, bar code reader 1
"Installation interval" between 4a and 14b, letterpress number reading device (CCD camera) 11 and bar code reading device 14a
Since it is known (set) in advance, if the set value and the difference match, it is determined that all three barcodes match, and the collation determination is a pass. If the difference between the set value and the calculation result does not match, it is determined that the three barcodes are not the same barcode, and the collation determination fails.

In this embodiment, the case of the bar code has been described, but other codes (for example, a T-shaped code) are used.
Of course, the present invention can be applied to the case, and the code reading device may be not only the scanner reading device but also a CCD camera or the like.

The number printing is not performed by the printing device,
Printing by an inkjet printer or a laser beam printer may be used.

[0046]

As described above, according to the present invention, for example, a general character number by printing is subtracted from each bar code number printed in advance on a plurality of collated roll papers. If this subtraction result matches the preset value, it is judged that accurate collation has been made,
If they do not match, it is determined that the collation is inappropriate, and therefore accurate collation determination can be performed without manual labor.

Further, since the preprinted bar code number and the general character number by printing are subtracted and it is judged whether or not it is a predetermined value, the accurate print bar code number and the general character number by printing are determined. Can be determined.
