Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing plate erroneous mounting detection device for detecting erroneous mounting of a printing plate mounted on a plate cylinder in a printing machine equipped with one or a plurality of printing plates.

[0002]

2. Description of the Related Art Conventionally, in newspaper printing, one or two folding machines and about eight to ten rotary machines are connected and combined.
One unit (usually, one set) of rotary press trains is configured. In a large-scale printing factory, a plurality of sets of rotary press trains are installed, and one or a plurality of newspapers having different page layouts are allocated to the newspaper distribution areas according to the number of print copies. The mounting position of the printing plate mounted on each rotary press in one set is determined by the rotary press operating conditions such as the number of newspaper pages, the number of rotary presses in one set, and the type of rotary press.

For example, to print a 32-page newspaper, 4
If one rotary press is used, eight types of printing plates are mounted on one plate cylinder. Further, two plates of the same printing plate are mounted on the same plate cylinder. Then, a total of 64 printing plates are required to print a 32 page newspaper. Therefore, when the operator mounts a large number of printing plates for each rotary press, there is a fear that the printing plates may be erroneously mounted.

In order to prevent such erroneous mounting of the printing plate, conventionally, the attention of the worker at the time of mounting and the visual inspection by the worker immediately after the start of printing depend on the inspection. Recently, due to the rationalization of personnel, the work volume of one worker has increased and the working density has been increased, and the number of newspaper pages and the printing speed have been increased, so that the paper inspection work has reached its limit. . In addition, if erroneous mounting of the printing plate is found by this paper inspection work, it is necessary to immediately stop the rotary press row and remount the erroneously mounted printing plate, which is a very complicated work.

[0005]

In the method in which the erroneous mounting of the printing plate is detected based on the judgment of the operator, the possibility of the erroneous mounting cannot be eliminated due to the misunderstanding of the operator. Also,
The paper inspection work itself is complicated, and the re-attachment of a printing plate that is found and erroneously mounted by the paper inspection work is more complicated. For this reason, it is strongly desired that erroneous mounting of a printing plate can be reliably detected without depending on the judgment of an operator and before starting printing.

Therefore, the present inventors have already proposed, for example, Japanese Patent Laid-Open No. 5-16938 as a printing plate erroneous mounting detection device capable of reliably detecting erroneous mounting of a printing plate. Intricate and not complete.

In FIG. 5, the same parts as those in FIG. 4 are designated by the same reference numerals, overlapping description will be omitted, and only different points will be described. A printing unit cover 15 is provided on the outer periphery of the plate cylinder 1. Second bar codes 9A, 9B, 9C, 9D are provided at positions where the printing unit cover 15 can be easily seen (positions on the front side in FIG. 4) corresponding to the first bar codes 7A, 7B, 7C, 7D. .

After being stored by the means 19, it is transmitted to the light receiving means (reception means) 23 by the transmission means 13 and taken in by the determination means 27.

Since the setting means position information and setting plane position information stored in advance in the setting storage means 25 are fetched into the judging means 27, the judging means 27 uses the actual body position information and the set body position information. In addition, the actual plate position information and the set plate position information are collated and determined.

If both pieces of information match, the printing plates 3A, 3
It is determined that B, 3C, and 3D are attached to the plate cylinder 1 at correct positions, and the rotary press 1 is operated. If the two pieces of information do not match, it is determined that the printing plates 3A, 3B, 3C, 3D are not attached to the plate cylinder 1 at the correct positions, and the operator again presses the printing plates 3A, 3B, 3C, 3D. The setup for attaching to the plate cylinder 1 is performed again.
The display unit 29 displays the result determined by the determination unit 27, etc., so that the operator can confirm the result.

Therefore, the printing plates 3A, 3B, 3 are attached to the plate cylinder 1.
It is possible to automatically and surely determine whether or not C and 3D are attached at the correct positions. Further, the structure of the device itself can be simplified as compared with the conventional one.

In FIG. 2, the same parts as those in FIG. 1 are designated by the same reference numerals, and the duplicate description is omitted. Explaining different points, the transmitting means 13 and the light receiving means 23 in FIG. 19 and the determination means 27 are directly connected by a cable, and other configurations are the same, and therefore, the same operation and effect as those in FIG. 1 are achieved.

FIG. 3 shows a structural block diagram which is an alternative to FIG. In FIG. 3, the same parts as those in FIG. 1 are designated by the same reference numerals to omit redundant description, and different points will be described. In FIG. 3, the setting storage means 25 and the determination means 27 are provided in the control device 21. It is not provided, but is provided in the manual scanner 11, and the storage means 19 is provided in the manual scanner 11.
Actual cylinder position information, plate position information and setting storage means 2

9D as a part of the plate cylinder 1 or the printing unit cover 15
Although it has been described as an example in which it is provided in a part of the above, it may be in any other position as long as it is easily operated.

Further, the plate identification symbol and the plate cylinder identification symbol are
As in the example of the above embodiment, the barcodes 7A to 7D,
9A to 9D are preferable, but barcodes 7A to 7D, 9
Instead of A to 9D, numbers, characters, figures, etc. may be used. Here, when the plate identification symbol and the plate cylinder identification symbol are barcodes 7A to 7D and 9A to 9D, the barcode reader 17 is used as the identification symbol reading means, but the plate identification symbol is a number, a character, or a figure. If so, it goes without saying that a means capable of appropriately reading these is used. The detection means uses the manual scanner 11 to easily read the plate identification symbol of the mounted plate by manual scanning by the operator, but this is automatically controlled by an arm mechanism or the like. It is also possible to read the plate identification symbols of the plate 3A to 3D mounted by using an unmanned operation. Further, although the manual scanner 11 is preferably portable for use with a built-in power source such as a battery in the examples of the above-described two embodiments, it may be connected by a cable or the like and supplied from the outside.
