Abstract

PURPOSE:To decrease spoilage having been generated after exchange of a printing plate by a method wherein newspaper edition number information of the printing plate is read controlling an image photographer with a positional controller, is discriminated with an image processor, is compared with a printing schedule to which a discriminating signal of an edition number or the like is given with a judging device, and whether the printing plate is correctly set or not is judged to be displayed with a display. CONSTITUTION:Newspaper edition number information of a printing plate is read by moving a CCD camera provided near a plate cylinder 10 in a width direction of the plate cylinder 10 controlling the CCD camera with a servo controller 3. An obtained image signal is sent to an image processor 5 via a camera switching device 4, and the image signal from the CCD camera 1 is discriminated. A discriminating signal of the discriminated edition number or the like is sent to a judge device 6, is compared with a printing schedule given preliminarily from a higher ranked press controller 7, and whether the printing plate is accurately set to a specific roll of a specific printing unit or not is judged. Said result is displayed with a display 8. Abovementioned operation is performed also with CCD cameras 1'-1''' in the same way.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a newspaper edition number monitoring device.

(Prior Art) A newspaper rotary printing press is composed of a plurality of printing units H. In each printing unit, printing plates corresponding to the number of newspapers are set at once to perform printing. At newspaper printing factories that have installed newspaper rotary printing machines, the composition of newspaper pages changes over time, starting with the first edition. Furthermore, the composition of the newspaper page is changed depending on the area where the newspaper is delivered.

Therefore, printing plates are frequently replaced. And as for whether or not the printing plates were replaced correctly.

Pick up the printed newspaper that comes out of the folding machine and
Confirmed visually by workers.

(Problem to be Solved by the Invention) Conventionally, as mentioned above, whether or not the printing plates have been replaced correctly has been checked by picking up the printed newspaper coming out of the folding machine and checking visually by one worker. Therefore, there was a problem in that it took a lot of time to change the printing plate, start printing, and complete the confirmation, resulting in the newsprint being wasted during that time.

The present invention has been proposed in view of the above-mentioned problems, and its object is to provide a newspaper plate number monitoring device that can reduce the amount of waste paper that occurs after printing plates are replaced.

(Means for Solving the Problems) In order to achieve the above-mentioned objects, the newspaper plate number monitoring device of the present invention has the following features:

a movable imaging device that images symbols, etc.; a position control device for the imaging device; characters captured by the imaging device;
An image processing device that identifies an image signal such as a symbol, and an identification signal such as a plate number recognized by the image processing device is compared with a print schedule given in advance from a higher-level press controller to print a predetermined roll of a predetermined printing unit. The apparatus includes a determination device for determining whether or not the printing plate has been correctly set, and a display device for displaying the result.

(Function) The newspaper plate number monitoring device of the present invention is configured as described above, and the image pickup device is controlled in the width direction of the plate cylinder while controlling the image pickup device installed near the plate cylinder by the position control device of the image pickup device. The newspaper version number information of the printing plate is read, the image signal obtained at that time is sent to an image processing device, the image signal is identified here, and the identification signal such as the identified version number is sent to a determination device. Here, the same identification signal is compared with the print schedule given in advance from the higher-level press controller to determine whether the printing plate has been correctly set on the predetermined roll of the predetermined printing unit, and the result is displayed on the display device. indicate.

(Embodiment) Next, the newspaper edition number monitoring device of the present invention will be explained using an embodiment shown in Fig. 1.2゜3.
(1") (1"') is a plurality of CCD cameras (imaging devices) that capture images of characters, symbols, etc. on printing plates attached to the plate cylinder (10) of each printing unit of a newspaper rotary printing press.

The CCD cameras (1) to (1'') are installed near the plate cylinder (10).
) to (1"'). This servo controller (position control device for the imaging device) controls the positions and speeds of the other CCD cameras (I') to (1"').
), but one illustration is omitted. Also (4) (4'
) is the camera switch, (5) (5' ) or the above CCD
An image processing device that identifies image signals such as characters and symbols from cameras (1) to (1''), (6) is a CCD camera (1
) to (1"') to identify the image signals such as characters and symbols captured by the image processing device, and the identification signals such as the version number recognized by the image processing device from the upper press controller (7) in advance. A determination device (8) that compares with a given printing schedule and determines whether or not a printing plate has been correctly set on a predetermined roll of a predetermined printing unit; and (8) a display device that displays the determination result of the determination device (6). Fig. 2 shows general newspaper edition number information on the printing plate. Fig. 3 shows the state in which necessary information is captured by CCD cameras (1) to (1''). It shows.

Next, the operation of the newspaper edition number monitoring device shown in FIG. 1.2.3 will be explained in detail. CCD camera (1) installed near the first plate cylinder (10) by a servo controller (3)
While controlling the CCD camera (1), the plate cylinder (lO)
is moved in the width direction of the printing plate to read the newspaper edition number information of the printing plate, and the image signal obtained at that time is sent to the image processing device (5) via the camera switch (4), where the CCD camera (
1), and sends the identified identification signal such as the version number to the determination device (6), which compares the same identification signal with the printing schedule given in advance from the upper press controller (7). Then, it is determined whether the printing plate is correctly set on a predetermined roll of a predetermined printing unit, and the result is displayed on a display device (8). The above action is C
The same process is performed for CD cameras (1°) to (P'').

(Effects of the Invention) As described above, the new plate number monitoring device of the present invention controls the imaging device installed near the seventh plate cylinder by the position control device of the imaging device, and moves the imaging device in the width direction of the plate cylinder. The newspaper version number information of the printing plate is read, the image signal obtained at that time is sent to an image processing device, the image signal is identified here, and the identification signal such as the identified version number is sent to a determination device. Here, the same identification signal is compared with the print schedule previously given from the higher-level press controller to determine whether or not the printing plate has been correctly set on the predetermined roll of the predetermined printing unit, and the result is displayed on the display device. Since the display is displayed, it can be quickly recognized whether or not the printing plate has been correctly set on the predetermined roll of the predetermined printing unit, which has the effect of reducing the amount of wasted paper that occurs after the printing plate is replaced.
