2. Description of the Related Art Printing impression cylinders are required to have high surface precision, and therefore it is necessary to periodically perform surface polishing and rubber rewinding at regular intervals. In addition, it is necessary to appropriately select and use the impression cylinder width (the width of the portion where the printing pressure is applied), the circumference, the rubber hardness, and the like according to the purpose of printing. It needs to be done quickly. Conventionally, such an impression cylinder is managed based on an ID (a unique ID assigned to each impression cylinder) or a number engraved by a bar code or the like attached to the impression cylinder. The information specific to the impression cylinder, such as the width and width, and the use history information were managed using a computer or ledger. However, the impression cylinder cannot read bar codes due to dirt in the printing process, and it takes time and effort to remove the dirt in order to read it. There was a problem that was impossible. Also, since the impression cylinder specific information and usage history information are recorded on a computer or ledger,
There were also problems such as inaccurate records and the inability to obtain information directly from the impression cylinder.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The impression cylinder management label of the present invention comprises a non-contact IC tag. Non-contact IC tags generally include a resin substrate, a metal coil pattern provided on the resin substrate,
And an IC chip connected to the coil pattern. When an electromagnetic wave is emitted from the reader to the non-contact type IC tag, an induced voltage is generated in the antenna coil, and the IC is
The tip is activated.

Hereinafter, an impression cylinder management system according to the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an example of an impression cylinder management system according to the present invention. FIG. 1 shows an example of a gravure printing press. An impression cylinder management label 11L is attached to a side surface (mirror surface) of the impression cylinder on an impression cylinder 11 attached to the printing press. A reader / writer 13 that communicates with the impression cylinder management label is installed directly above the impression cylinder management label or at a position facing the label, and performs writing of data to the impression cylinder management label and reading of data from the label. on the other hand,
The portion of the printing plate cylinder 12 that contacts the shaft (plate cylinder axis)
A counter 15 for counting the number of rotations (counter value) of the plate cylinder is attached. Preferably, the impression cylinder management system includes a detector 16 for detecting the attachment / detachment of the impression cylinder near the impression cylinder mounting portion of the printing press. This makes it possible to detect the replacement of the impression cylinder and clarify the start point and the end point of management data acquisition accompanying the replacement. In FIG. 1, reference numeral 19 denotes an ink pan, and excess ink adhering to the plate cylinder 12 rotated in the ink pan is scraped off by a doctor blade (not shown) and transferred to the printing paper 30 on which the ink in the plate surface cell runs. Printed.

The counter value read or counted by the reader / writer 13 and the counter 15 is sent via a line 17 to a computer device 2 having an arithmetic unit and a storage device.
0, the computer device 20 calculates the number of meters used for printing based on the counter value from the counter 15 and the circumference of the plate cylinder, and adds it to the number of used meters of the impression cylinder to calculate the cumulative number of used meters. And so on. The data on the impression cylinder management stored in the computer device 20 is displayed on the display device.

FIG. 2 is a view showing an impression cylinder and an impression cylinder management label adhered to the impression cylinder mirror surface. The impression cylinder management label 11L may be affixed to any position of the impression cylinder, but the position where it can communicate with the reader / writer without contact is actually the mirror surface (side surface) 11s of the impression cylinder.
It will be limited to. The impression cylinder is generally formed by attaching shafts to both ends of a hollow roll made of steel, winding synthetic rubber or the like around the roll surface, and polishing the roll. Therefore, communication is impossible within the metal shaft shaft 11c or the inside of the body, the shaft end serves as a mounting portion of the bearing, and the entire shaft is likely to be damaged due to much contact with the transport equipment and the like. The impression cylinder is easily stained due to ink splashing from the plate cylinder, and the control label sticking part is also stained.However, it can be communicated wirelessly without contact, so there is no problem in use, and repeated use as long as the label is not damaged There is an advantage that you can.

FIG. 3 is a diagram showing a specific example of the impression cylinder management label. The impression cylinder management label 11L is made of a non-contact IC tag, forms a coil pattern 3 on a base material 4 such as a solvent-resistant plastic, and forms a resonance circuit with the coil and the capacitance element to receive a radio wave of a certain frequency. Can be sent. Generally 135 kHz (medium wave), 13.56 MH
z, a frequency band of 2.45 GHz (microwave) is used. In the case of the illustrated example, the coil pattern forms a jumping circuit on the back surface of the base material 4 by the conductive member 5 and is connected to the bump on the back surface of the IC chip 2 by the coil connection terminal 3c. In this case, the capacitance element is built in the IC chip. The IC tag can be formed by forming a coil pattern 3 by photo-etching or etching after resist printing on an aluminum foil laminated on a base material, mounting an IC chip, and providing a protective coating. Its size can also be about 50 mm × 50 mm or less.

Since the IC chip 2 has a memory, it is possible to store certain items such as the impression cylinder ID, the impression cylinder circumference, the impression cylinder width, the date of starting use, the number of meters used, and the rubber hardness. Although it is possible to adopt a system in which these data including the number of used meters are stored only in the label itself, the label is often damaged due to the work environment. Therefore, it is preferable to use an external storage device together. The shape of the label 11L is not limited to a rectangular shape or a square shape as shown in FIGS. 2 and 3, but may be a circular arc shape or a flat annular shape which is fitted from the shaft shaft end and adhered. Various methods can be used for sticking to a mirror surface, such as sticking with an adhesive or the like, or sticking with a tape or the like, but it is necessary to prevent peeling in a solvent such as ink or its atmosphere.

The reader / writer communicates with the label in a non-contact manner, and is set within a communication distance of several cm to several tens cm. Reading of information from the impression cylinder management label and writing of information to the label are performed as follows. (1) Information reading When an impression cylinder is mounted on a printing press, a detector (sensor) for the impression cylinder
Reference numeral 16 detects "wear" of the impression cylinder, and a data reading command is issued from the computer device based on the signal. The reader / writer 13 obtains the impression cylinder ID from the management label 11L attached to the impression cylinder mirror surface 11s from the data reading unit.
Read each data of / Impression cylinder circumference / Impression cylinder width / Start date of use / Number of meters used. At the same time, the current counter value is read from the counter 15. This is because the initial value of the counter value may not be “0”. Both data are transmitted to the arithmetic unit 21 of the computer. On the other hand, the arithmetic unit receives the data transmitted from the data reading unit and the counter, and stores the data in the storage device 22. Further, the received data is transmitted to the display device 23.

(2) Writing of Information When the impression cylinder is detached from the printing press, the detachment detector 16 of the impression cylinder detects the "detachment" of the impression cylinder. 21 and the difference from the first read count value is calculated. The number of meters used is calculated from the product of the value and the circumference of the plate cylinder, and the number of meters used this time is added to the number of meters used at the end of the previous printing from the impression cylinder information (number of meters used) stored in the storage device. By doing so, the data of the used meter number and the counter value of the storage device 22 are updated, and the newly calculated used meter number is written to the impression cylinder management label from the data writing unit.

FIG. 4 is a diagram showing an example of a screen displayed on the display device. On the screen, control values such as an impression cylinder ID, an impression cylinder circumference, a use start date, a counter value, an impression cylinder width, and the number of meters used are displayed. In addition, it is free to include data such as rubber hardness and rubber material.
When the impression cylinder reaches a certain number of used meters, it is necessary to grind the surface or rewind rubber, and these are performed based on the date of starting use and the number of used meters.

FIG. 5 is a diagram showing an example of impression cylinder management data. As in the case of the display device, the impression cylinder ID (identification I
D), impression cylinder circumference, impression cylinder width, date of start of use, number of meters used, etc. are recorded. These data can be sequentially updated during printing based on the calculation result of the calculation device. The data of such an impression cylinder management label can be read by the reader / writer 13 of the printing press. However, if a handy read / write terminal is provided, it is possible to read and write data from the terminal. In this case, it is also possible to read and write specific data.

[0017]

As described above, in the impression cylinder management system of the present invention, the impression cylinder management label in which data such as the ID of the impression cylinder is electronically recorded is affixed to the mirror surface of the impression cylinder. Since the data of the management label can be read and written by the writer without contact from outside, there is no need to clean or clean the impression cylinder in order to check the ID of the impression cylinder as before. It can contribute to labor saving. In addition, in the impression cylinder management system and the impression cylinder of the present invention, the usage status of the impression cylinder can be recorded in real time, and recording, inputting, or reading out of data does not take time, which also contributes to labor saving in this aspect. it can.
