Then, the management system 20 comprises a reading device (reading means) 32 for electrically or magnetically reading the cylinder identification information from the data carrier 14 of the printing cylinder 11 carried by the most upstream carrying device 21; Transport device 2
The temporary storage warehouse management device (storage means) which causes the printing cylinders 11 to be carried into an empty temporary storage place (storage place) of the temporary storage warehouse 22 by the transport storage device 1 and the printing cylinders 11 to be unloaded from the temporary storage warehouse 22 by the transport device 23. ,
Take-out means) 33.

Here, the temporary storage warehouse 22 is provided with a number of temporary storage locations for storing the printing cylinders 11 one by one, and each temporary storage location is distinguished from the other temporary storage locations. Temporary storage location identification information is set.

The temporary storage warehouse management device 33 pairs the cylinder identification information of the printing cylinder 11 read by the reading device 32 with the temporary storage location identification information of the temporary storage location where the printing cylinder 11 is stored. One is stored in correspondence. Thereby, when the required printing cylinder 11 is taken out by the transport device 23, the cylinder identification information of the printing cylinder 11 is input, and the temporary storage location identification information corresponding to the cylinder identification information is input. The printing cylinder 11 is taken out from the temporary storage place having the above.

Further, the management system 20 is a reading device (reading means) for electrically or magnetically reading the cylinder identification information from the data carrier 14 of the printing cylinder 11 whose outer diameter has been measured by the cylinder diameter measuring device 25. 35, a storage warehouse management device (storage means, display means) for transporting the printing cylinders 11 to an empty storage place of the storage warehouse 26 by the transport device 23 and unloading the printing cylinders 11 from the storage warehouse 26 by the transport device 27. , Extraction means)

Here, the storage warehouse 26 is provided with a number of storage locations for storing the printing cylinders 11 one by one, and each storage location has a storage location for identifying each of the printing cylinders 11 from other storage locations. Location identification information is set.

Then, the storage warehouse management device 36 associates the cylinder identification information of the printing cylinder 11 read by the reading device 35 with the outer diameter value of the printing cylinder 11 measured by the cylinder diameter measuring device 25 on a one-to-one basis. And stores the cylinder identification information of the printing cylinder 11 in one-to-one correspondence with the storage location identification information of the storage location where the printing cylinder 11 is stored.

Thus, when the required printing cylinder 11 is taken out by the transport device 27, the storage / warehouse management device 36 receives the cylinder identification information of the printing cylinder 11, and The printing cylinder 11 is taken out from a storage location having storage location identification information corresponding to the information.

Here, the operation schedules of all the printing presses are input to the storage warehouse management device 36, and the storage warehouse management device 36 basically performs the printing of the storage warehouse 26 based on the operation schedule. Although the cylinders 11 are carried out, if there are a plurality of printing cylinders 11 that can be used for a predetermined printing press, the printing cylinders 11 to be used are selected from among them, and the order of carrying out is determined according to the order. And can be sorted.

That is, for example, the storage warehouse management device 36
When a plurality of printing cylinders 11 for a predetermined printing press based on the operation schedule are stored in the storage warehouse 26, the cylinder identification information of these printing cylinders 11 is simultaneously displayed in the order of larger or smaller outer diameter. It is designed to be displayed on the monitor. When the printing cylinder 11 is carried out of the storage warehouse 26, if the operator selects and inputs cylinder identification information in the order based on the size of the outer diameter based on the monitor display, the storage warehouse management device 3
No. 6 causes the printing cylinders 11 to be carried out of the storage warehouse 26 in an order based on the size of the outer diameter. That is, if the operator selects and inputs the cylinder identification information in order of increasing outer diameter, the storage warehouse management device 36 causes the printing cylinders 11 to be carried out of the storage warehouse 26 in order of increasing outer diameter. If the operator selects and inputs the cylinder identification information in ascending order of the outer diameter, the storage warehouse management device 36
Means that the printing cylinders 11 are carried out from the storage warehouse 26 in ascending order of outer diameter.

The storage warehouse management device 36 also instructs the temporary storage warehouse management device 33 to carry out the printing cylinder 11 from the temporary storage warehouse 22 based on the operation schedule. In this case, when there are a plurality of printing cylinders 11 to be carried out for a predetermined printing press, the temporary storage warehouse management device 33 carries out the temporary storage order (so-called first-in first-out).

Next, the flow of management of the printing cylinder 11 using the management system 20 will be described.

The printing cylinder 1 returned from the printing process
1 is a step of reading the cylinder identification information of the data carrier 14 by the reading device 32 (this is a step of electrically or magnetically reading the cylinder identification information of the printing cylinder 11 stored in the data carrier 14). ).
Then, the reading device 32 outputs the read cylinder identification information to the temporary storage warehouse management device 33.

Then, the temporary storage warehouse management device 33 causes the transport device 21 to store the printing cylinder 11 in a predetermined empty temporary storage location of the temporary storage warehouse 22 and reads the printing cylinder 11 read by the reading device 32. 11
Is stored in a one-to-one correspondence with the cylinder identification information of the temporary storage location for storing the same (this is the data carrier 14 of the printing cylinder 11 when storing the printing cylinder 11). This is a step of storing the cylinder identification information read from the printer and the storage location for storing the printing cylinder 11 in association with each other.)

Further, the temporary storage warehouse management device 33 outputs the cylinder identification information of the temporarily stored printing cylinder 11 to the storage warehouse management device 36. Then, the storage warehouse management device 36 recognizes that the printing cylinder 11 having the cylinder identification information is stored in the temporary storage warehouse 22.

Although a large number of printing cylinders 11 are stored in the temporary storage warehouse 22, as described above,
In which temporary storage place each printing cylinder 11 is stored is managed. The printing cylinder 11 basically returns from the printing press as a set of eight printing cylinders.

On the other hand, the storage / warehouse management device 36 basically uses a set of eight printing cylinders 11 to be used in a printing machine which is approaching a predetermined start of operation based on the printing machine operation schedule. The identification information is output to the temporary storage warehouse management device 33. Then, the temporary storage warehouse management device 33
Causes the transport cylinder 23 to remove the printing cylinder 11 from the temporary storage location corresponding to the input cylinder identification information, and as a result, the printing cylinder 11 having the input cylinder identification information is stored in the temporary storage warehouse 22. (This is the step of taking out the printing cylinder 11 from the storage location stored in association with the cylinder identification information stored in the data carrier 14 of the printing cylinder 11 based on the cylinder identification information).

The printing cylinder 11 taken out of the temporary storage warehouse 22 is removed after the copper plating and the chromium plating are peeled off in a ballad peeling step (not shown) during the transportation of the transportation device 21 or the transportation of the transportation device 23. Copper plating is performed by a copper plating apparatus (not shown), and the printing cylinder 11 after the copper plating is applied to the printing cylinder 11. , The cylinder identification information of the data carrier 14 is read.

Then, the cylinder diameter measuring device 25 outputs the outer diameter measured for the printing cylinder 11 to the storage warehouse management device 36, and the reading device 35 reads the cylinder identification read for the printing cylinder 11. The information is output to the storage warehouse management device 36. Then, the storage warehouse management device 36 sets the printing cylinder 1
1 is stored in a one-to-one correspondence with the measured outer diameter and the cylinder identification information (this is the printing cylinder 11 before plate making).
Is a step of measuring the outer diameter of the printing cylinder 11 and storing the outer diameter in association with the cylinder identification information read from the data carrier 14 of the printing cylinder 11).

Then, the storage warehouse management device 36 stores the printing cylinder 11 in the storage warehouse 26 by the transport device 23.
And store the cylinder identification information of the printing cylinder 11 read by the reading device 35 in one-to-one correspondence with the storage location identification information of the storage location storing the printing cylinder 11 ( This is the process of storing the cylinder identification information read from the data carrier 14 of the printing cylinder 11 and the storage location where the printing cylinder 11 is stored when storing the printing cylinder 11).

The storage warehouse 26 has a large number of printing cylinders 1.
1 is stored, and as described above, in which storage location each printing cylinder 11 is stored is managed. The printing cylinders 11 are basically transported from the temporary storage warehouse 22 as a set of eight printing cylinders.

On the other hand, based on the operation schedule of the printing press, the storage warehouse management device 36 basically prints a set of eight printing cylinders 11 corresponding to a set of eight printing cylinders 11 to be used in a printing press near the start of the predetermined operation. Read the cylinder identification information including the model number of the machine. And the storage warehouse management device 36
Compares the outer diameters of all of these printing cylinders 11 and arranges the cylinder identification information in the order of increasing (rearward) or decreasing (ascending) outer diameters, and simultaneously displays the cylinder identification information on a monitor (this is the pre-plate making process). In order of larger or smaller outer diameter,
This is a step of displaying the cylinder identification information stored in the data carrier 14 of the printing cylinder 11 on a monitor).

FIG. 3 shows an example of the display. In FIG.
At the top, the model of the printing press is displayed, and at the bottom,
The model of the printing press corresponding to the printing cylinder 11 which is a part of the cylinder identification information is displayed in the leftmost column.
On the right side, the ID number of the printing cylinder 11 which is a part of the cylinder identification information is displayed, on the right side, the outer diameter is displayed, and on the right side, the diameter difference from the upper side is displayed. Has become. In this display example, the outer diameters are displayed from the top in descending order. Further, on the lower left side, a key input area for instructing the calling of the printing cylinder 11 is displayed, and on the right side, a key input area for switching between a large order (descending order) and a small order (ascending order) is displayed. ing. Note that, instead of expressing the size of the outer diameter by a numerical value, the size of the outer diameter can be expressed by a circle, or a combination thereof can be used.

Here, when the printing cylinders 11 are mounted in order of increasing outer diameter for convenience of mounting on a printing press, the operator stores the cylinder identification information in order of increasing outer diameter based on the monitor display. This is to be selectively input to the management device 36. Then, the storage warehouse management device 36 sends the printing cylinders 1 from the storage warehouse 26 by the transport device 27 in the descending order of the outer diameter.
1 is taken out. On the other hand, when the printing cylinders 11 are mounted in ascending order of the outer diameter, the operator inputs the cylinder identification information to the storage warehouse management device 36 in ascending order of the outer diameter based on the monitor display. Then, the storage warehouse management device 36 causes the transport device 27 to remove the printing cylinders 11 from the storage warehouse 26 in ascending order of the outer diameter.

At this time, the printing cylinder 11 is transferred from the storage location corresponding to the input cylinder identification information to the transport device 2.
7, the printing cylinder 11 having the input cylinder identification information is unloaded from the storage warehouse 26 (this corresponds to the cylinder identification information stored in the data carrier 14 of the printing cylinder 11). This is a step of taking out the printing cylinder 11 from the stored storage location based on the cylinder identification information).

Instead of the operator inputting the cylinder identification information to the storage warehouse management device 36, the storage warehouse management device 36 automatically prints the cylinder identification information from the storage warehouse 26 using the transport device 27 in order of increasing or decreasing outer diameter. The use cylinder 11 may be taken out.

Then, the printing cylinder 11 is transported by the transport device 27 to one of the engraving plate making device 28 and the corrosion plate making device 29, where plate making is performed on the copper plating surface. At 30, the plate making surface is chrome-plated and sent to the printing process in the order in which it was taken out of the storage warehouse 26.

According to the above-described embodiment, the data carrier 1 of the printing cylinder 11 including the data carrier 14 storing the cylinder identification information for distinguishing from the others is stored.
Since the reading devices 32 and 35 electrically or magnetically read the cylinder identification information stored in the storage device 4, the reading is performed due to stains at the time of printing or corrosion due to chemical treatment as in the case of the engraved ID number. It won't be difficult.

Therefore, even if the printing cylinder 11 is stained during printing or is corroded by a chemical treatment, it is possible to always reliably read the cylinder identification information for identifying it from the others.

Since the cylinder identification information is read electrically or magnetically, the reading and input can be automated.

Therefore, it is possible to eliminate unstable factors such as visual observation and input by the operator.

When the cylinder diameter measuring device 25 measures the outer diameter of the printing cylinder 11 before plate making, the storage / warehouse management device 36 determines the outer diameter of the printing cylinder 11 measured by the cylinder diameter measuring device 25 in the printing. Since the printing cylinder 11 is stored in association with the cylinder identification information read from the data carrier 14 of the printing cylinder 11, the printing cylinder 11 can be searched from the outer diameter by reading the storage.

Therefore, when it is desired to use the printing cylinder 11 having a desired outer diameter, it can be reliably found.

Further, the storage / warehouse management device 36 controls the printing cylinders 1 in order of increasing or decreasing outer diameter before plate making.
Since the cylinder identification information stored in one data carrier 14 is displayed side by side, the operator can clearly recognize the printing cylinders 11 in the order of larger or smaller outer diameter before plate making.

Therefore, when it is desired to use the printing cylinders 11 in order of increasing or decreasing outer diameter before plate making,
The operator can clearly recognize which printing cylinder 11 should be used.

In addition, the temporary storage warehouse management device 33 and the storage warehouse management device 36 associate the cylinder identification information read from the data carrier 14 of the printing cylinder 11 with the storage location where the printing cylinder 11 is stored. By reading the storage, the printing cylinder 1 is stored.
1 can be recognized in which storage location.

Therefore, when a desired printing cylinder 11 is desired to be used, it can be reliably found.

Further, the transport devices 23 and 27 take out the printing cylinder 11 from the storage location stored in association with the cylinder identification information stored in the data carrier 14 of the printing cylinder 11 based on the cylinder identification information. The printing cylinder 11 can be taken out from the storage location where the printing cylinder 11 is stored.

Therefore, when a desired printing cylinder 11 is desired to be used, it can be reliably taken out.

In the above embodiment, the case where the temporary storage warehouse 22 is provided has been described as an example. However, as shown in FIG. 4, the temporary storage warehouse 22 may not be provided. In this case, the transport device 21, the temporary storage warehouse 22, the reading device 3
2 and the temporary storage warehouse management device 33 is not provided, the transport device 23 receives the printing cylinder 11 directly from the printing process, performs the ballad removal process in the ballad removing process during the transportation by the transport device 23, and performs the copper plating process.

According to the printing cylinder management system of the present invention, when the measuring means measures the outer diameter of the printing cylinder before plate making, the storage means stores the printing cylinder measured by the measuring means. Since the outer diameter is stored in association with the cylinder identification information read from the data carrier of the printing cylinder, the printing cylinder can be searched from the outer diameter by reading the storage.

Therefore, when it is desired to use a printing cylinder having a desired outer diameter, this can be reliably found.

According to the printing cylinder management system of the present invention, the display means displays the cylinder identification information stored in the printing cylinder data carrier in the ascending or descending order of the outer diameter before plate making. The display allows the operator to clearly recognize the printing cylinders in the order of larger or smaller outer diameter before plate making.

Therefore, when it is desired to use printing cylinders in order of increasing or decreasing outer diameter before plate making, the operator can clearly recognize which printing cylinder should be used.

According to the printing cylinder management system of the ninth aspect of the present invention, the storage means associates the cylinder identification information read from the data carrier of the printing cylinder with the storage location where the printing cylinder is stored. Since the print cylinder is also stored, it is possible to recognize in which storage place the printing cylinder is stored by reading the storage.

Therefore, when a desired printing cylinder is desired to be used, it can be reliably found.

According to the printing cylinder management system of the tenth aspect of the present invention, the ejecting means determines the cylinder identification information from the storage location stored in association with the cylinder identification information stored in the data carrier of the printing cylinder. Since the printing cylinder is taken out based on the information, the printing cylinder can be taken out from the storage location where the printing cylinder is stored.

Therefore, when it is desired to use a desired printing cylinder, it can be taken out without fail.
