For this reason, the collating operator proceeds with the collating operation while observing and operating these monitor devices 22 arranged over a long distance.

The appearance of the monitor device 22 will be described.
As shown in FIG. 2, a patrol light 22g for notifying that an emergency state has occurred in the collating piece device such as the compulsory stop of the collating piece device is arranged on the upper portion of the housing of the monitor device 22, An operation panel is arranged together with an LCD (Liquid Crystal Display) 22a. The operation panel is provided with various input setting means 22b, an LED display (light emitting element) 22c corresponding to the input setting means, and a backlight switch 22d.

Further, among the input setting means 22b arranged on the operation panel, the input setting means 22b ′ for setting the inspection mode is composed of six inspection mode setting switches, each of which has an LED display (light emitting element). ) 22c is arranged.
As shown in the enlarged view on the right side of FIG. 2, the LED display (light emitting element) 22c has three light emitting elements 22c-1a to 22c and 22c-2a to 22c arranged on the upper and lower stages, respectively, and input setting means. In synchronism with the operation of 22b ′ (more specifically, in synchronism with the pressing of the switch constituting the input setting means 22b ′), the lamp is lit for a predetermined short time. Therefore, the operation of the input setting unit 22b ′ can be confirmed by turning on the corresponding light emitting elements 22c-1a to 22c and 22c-2a to c along with the operation of the input setting unit 22b ′.

Next, the line control unit 30 is connected to the plurality of piece disorder checking units 20-1 to 20-n via a network (I / O), and controls the disorder check unit 20 with one or a minimum number. Is.
As shown in FIG. 4, the line control unit 30 includes a standard time supply means 30b (a time server 30b-1 and a radio clock 30b-2) for supplying a standard time common to each collating piece, and each collating piece apparatus 10-1 to 10-1. An input operation means 30d for inputting various setting information to the piece control means 22k for each n, a display means 30c for displaying an input operation by the input operation means 30d, an operating state of each irregularity inspection device 20, etc., and each piece irregularity inspection section 20 -A total of the analysis information from 1 to n and an error aggregation / analysis means 30e for collecting and analyzing the collation management information aggregated / analyzed by the error aggregation / analysis means 30e, which can be taken offline 30f, the start signal 31 from the starter 15, the pulse signal from the encoder 32, the input signal from the input operation means 30d, etc. And a main control unit 30a for controlling the in-control unit 30.
Further, the main control means 30a receives an error check information (disorder occurrence information) from the corresponding piece check inspection unit 20-1 to 20-n when a check error occurs in the collating piece devices 10-1 to 10-n. In addition, the entire collating apparatus 10 is automatically stopped, the setting information is output to the piece disorder checking units 20-1 to 20-n based on the setting information by the input operation means 30d, or the stop switch in the collating apparatus 10 is turned on. It has a function of forcibly stopping the entire collating apparatus when operated by an operator.

Next, as shown in FIGS. 1 and 4, the irregularity inspection information management apparatus 40 is provided offline with the piece irregularity inspection units 20-1 to 20-n and the line control unit 30.
The irregularity inspection information management device 40 is configured to perform various collations stored in a portable memory (not shown) provided in the piece irregularity inspection units 20-1 to 20-n and a portable memory 30f provided in the line control unit 30. It has a function of reading management information, analyzing and storing the data, and a function of reading and displaying them appropriately.

The operation of the randomness inspection machine 20 of the present invention configured as described above will be described below.
The signatures of the collating device 10-1 to n of the collating device 10 are picked up by the image pickup means 21 of the corresponding piece collating inspection units 20-1 to 20-n, and the picked up images are imaged by the image processing unit 21a. If it is judged that the standard image has been processed and stored in advance and is in disorder, the inspection information is added with the device information stored in the device information storage means 22f, Via the control means 22k, it is stored in the inspection information storage means 22e and output to the line control unit 30.
The main control means 30a outputs a control signal for the collation apparatus 10 based on the inspection information and device information. For example, when the messed up state has occurred beyond the allowable setting set in the piece scramble inspection units 20-1 to 20-n, the entire collating apparatus 10 is stopped via the network (I / O). A control signal is output.
The inspection information and device information are analyzed for error conditions by the error counting / analysis means 30e, and the analysis results are stored and stored in the portable memory 30f.
The analysis result stored in the portable memory 30f is further analyzed in detail by the random inspection inspection information management device 40 provided offline without going through the network (I / O).

Here, as shown in FIGS. 1 and 4, the starter 15 generates a start signal 31 every rotation of the drum 14, and the piece control means 22k supplies the start signal supplied through the main control means 30a. By counting up the signal 31, it becomes possible to specify the signature in the piece order checking unit 20-1 to 20-n when the order is incorrect.
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 determined by the pulse signal. Is set.

Then, as shown in FIG. 3, the pulse count is started at the timing when the start signal 31 is generated, and after a predetermined count wait period A, an illumination LED (not shown) is attached to the signature 1 for 50 ms. Illuminates and captures a signature image, captures the captured image of the signature 1 into the image processing unit 21a at a predetermined timing, and performs a typographical determination with the reference image (period B).
The determination result is output to the piece control means 22k and stored in the inspection information storage means 22e (period C).
Here, the inspection result of the signature 1 is displayed as data in the inspection information display area 22a ′ on the right side of the display screen of the LCD (liquid crystal display device) 22a.
The next signature 2 is also subjected to a random inspection at the same timing as the signature 1, and the inspection result is similarly displayed using the LED display (light emitting element) 22c-1a.

Here, when the piece control means 22k detects that any of the input setting means 22b on the operation panel is not operated for a predetermined time (for example, 1 minute) by the built-in backlight timer, the backlight control 22d is connected to the backlight switch 22d. Outputs a light-off signal. As a result, the backlight switch 22d is forcibly turned off.
On the other hand, when the backlight is off, if any input setting means 22b on the operation panel is operated, or if a collation error occurs and the collation apparatus 10 stops, a collation error occurs. The piece control means 22k in the monitor device 22 of the generated colling piece outputs a backlight lighting signal to the backlight switch 22d, and the backlight switch 22d in the monitor device 22 is forcibly turned ON. When the input setting means 22b is operated in this way, the backlight is turned on by the first button operation, and input can be performed by the second and subsequent button operations.

When the backlight is extinguished in this way, naturally, the display of the inspection result in the inspection information display area 22a ′ of the monitor device 22 cannot be observed by the operator.
Therefore, in the present invention, the display of the inspection result is displayed on the six LED indicators (light emitting elements) 22c-1a to 22c-1a arranged corresponding to the inspection mode setting means 22b 'of the input setting means 22b on the operation panel. c, and blinking display using 22c-2a to c (FIG. 2).

Here, when the coincidence rate when comparing the signature image information and the standard image information exceeds 90% (indicated by << A >> in FIG. 6), it is determined that the collation is normally performed. ), The six light emitting elements 22c-1a-c and 22c-2a-c arranged in two upper and lower stages are controlled to blink so that the lighting state flows from the upper right to the lower left as indicated by arrows. Is done. In addition, ◯ indicates a lit state, and ● indicates a turned off state.
Further, when the coincidence rate is 80 to 89% (indicated by << B >> in FIG. 6, the collation state is within the set allowable range but should be noted), the six light emission. The elements 22c-1a to 22c and 22c-2a to 22c are controlled to blink so that the lighting state flows from the upper left to the lower right as indicated by arrows.
Further, when the coincidence rate is 79% or less (indicated by << C >> in FIG. 6, the collation is not normal), the six light emitting elements 22c-1a to 22c-2a -C are controlled to blink so that the lighting state flows from the lower left to the upper right as indicated by arrows.
At this time, the lighting time of the light emitting element is controlled to be 40 ms, and the next light emitting element is sequentially turned on at the time interval. Such cyclic flashing control is performed by the LED flashing control means 22k ′.
When the inspection of one signature is finished and the start signal 31 for the next signature inspection is input to the LED blinking control means 22k ′, the above-mentioned cyclic blinking control is reset, and the next signature is confirmed. Until the inspection result is input to the LED blinking control means 22k ′, the apparatus waits at an initial display position (a position where all the light emitting elements are turned off or a position where only 22c-1a is lit).

Next, the control flow of the collation inspection machine 20 configured as described above will be described with reference to FIG.
When the input setting means 22b on the operation panel is not operated (S1), the backlight timer of the piece control means 22k is updated (S2).
Here, when a signal from the starter 15 is input (S3), as shown in FIG. 3, an image capture process and an image comparison process are performed (S4), and a coincidence rate determination process is performed (S5).
This determination result is compared with an allowable value set in the piece disorder checking units 20-1 to 20-n of the collating piece devices 10-1 to 10-n, for example, an allowable number of consecutive errors, a size of coincidence rate, etc. (S6). If it is out of the allowable range (S6, N), error processing such as generating an alarm sound is performed (S10). Following this error processing, the backlight is turned on (S11), the patrol light 22g is turned on, and the light emitting element blinks in “rank C” (S12). In such a state, the collation worker specifies the collation piece device on which the error is displayed, and performs an error canceling process (S14).
In the coincidence rate determination process (S5), if it is within the range of the acceptable scramble value set in the piece scramble inspection units 20-1 to 20-n (S6, Y), if the backlight is lit (S7) Y) The inspection result is displayed as data in the inspection information display area 22a ′ of the LCD display section 22a (S9). If the backlight is not lit, the light emitting element 22c is controlled to blink to display the matching rate by rank ("rank A" or "rank B") (S8). In this case, since it is not necessary to cancel the error (S13, N), the inspection for the next signature is continued without performing the error canceling operation.

  When the input setting means 22b on the operation panel is operated in S1, the backlight timer is reset at that time (S21), and the backlight is turned on when the backlight is turned off (S22, OFF). (S24) At that time, the backlight timer is started. When the backlight is lit (S22, ON), it is determined whether or not the operation content of the input setting means 22b is present (S23). Based on the operation, setting change processing and history display in the piece disorder checking unit are determined. Processing is performed (S25), and a backlight timer is set at that time (S26).

Since the present invention is configured as described above, when the backlight is turned off, the LED in the setting mode can be blinked in an illumination manner so that the inspection state when the backlight is turned off can be easily seen. It is possible to reduce the power consumption of 22 due to erroneous operation (error level or inspection mode setting error), inspection interruption due to setting change operation or history display operation, machine adjustment deficiency (starter sensor misalignment), etc. When it is in an uninspected state, the operator of the collation apparatus 10 can be surely recognized, so that the bookbinding operation is continued, and an event that is originally detected as an error due to a mistake in loading the signature, etc. Even if there is a problem, it is possible to reliably avoid a situation in which a defective product is handled as a good product without noticing that it is in an uninspected state.
Further, since the blinking control is performed at a predetermined timing in synchronization with the starter signal, it can be seen that the inspection is updated.
In addition, because the rank of the matching rate indicating the inspection result is set and the degree of matching is notified in real time, it is easy for the matching rate to fluctuate (being inspected) due to deviation, blurring, brightness change, etc. I can grasp.
Furthermore, without providing a dedicated display, it is possible to make an operator visually check the results of random inspection by using an LED display that displays the setting operation and the setting mode, and the power consumption of the LED display element is a backlight. Since it is negligibly small compared with the power consumption in the case of blinking, the monitor device can be configured compactly and inexpensively.

Although the light switch is forcibly controlled to be turned off, there is a so-called automatic mode. However, as shown in FIG. 2, by providing a backlight switch 22d on the operation panel of the monitor device 22, the operator can turn on the backlight. A so-called manual mode can be added so that ON-OFF can be arbitrarily performed. Even in such a configuration, it is configured to automatically return to ON by the operation of the input setting means 22b on the operation panel or when a collation error occurs.

(2) In the above embodiment, the light emitting elements arranged in the inspection mode setting means 22b ′ among the input setting means 22b provided on the operation panel of the monitor device 22 reflect the inspection result of the random inspection machine.

(3) In the above embodiment, the random inspection result is notified by the blinking control of the light emitting element. However, the inspection result is displayed by controlling the luminance change of the light emitting element or the light emitting element to change the color. It can also be configured. Moreover, it can also comprise so that it may display by these combination.
For example, as described above, when the coincidence rate is A, the light-emitting element is lit green, when the coincidence rate is B, the orange light is lit, when the coincidence rate is C, the red light is lit, and when an error condition further occurs. The collating operator can be made to recognize the inspection result by, for example, a blinking display with a short blinking interval.

(4) In the above embodiment example, the inspection result when the backlight is lit is displayed in the inspection information display area 22a ′ of the LCD display unit 22a. The display in the inspection information display area 22a ′ is performed. At the same time, an LED display (light emitting element) 22c (corresponding to the input setting means 22b) (in this embodiment, as shown in FIG. 6, the LED display ( The light emitting element) 22c-1a) may be displayed by blinking control. In this case, as shown in FIG. 6, during the normal inspection, the LED display (light emitting element) 22c is controlled to blink, but when a collation error occurs, it is switched to fast blinking. To be displayed.
In this way, by performing display using the LED display (light emitting element) 22c, even if the collation worker is far away from the monitor device 22d, the LED display (light emitting element) having relatively high luminance. ) Since blinking by 22c can be observed, the collation result can be recognized to a certain extent, which is preferable.

(5) In the above embodiment, the collation state is displayed in three stages (A to C), but the number of divisions can be set as appropriate. Moreover, the setting of the range of the coincidence rate in each division at that time can also be set as appropriate.
