[Industrial application fields]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing plate transfer processing apparatus that automatically extracts a plate cylinder to be shared when sharing a plate cylinder (print printing) in gravure printing.
[0002]
[Prior art]
In gravure printing, it is important to share the plate cylinder among different printing items in order to reduce the purchase and maintenance costs of the plate cylinder and to store it in a limited space. In fact, in order to share the plate cylinder, the preprinted pattern is dropped (referred to as “release plate”), and it is diverted. Is called diversion. Conventionally, this printing plate conversion work is performed by a plate operator manually confirming information such as the plate cylinder circumference and the plate cylinder width and manually extracting the plate cylinder to be used for printing plate printing from the printing work schedule. Yes.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional method, extraction is performed taking into account the printing work schedule, but the accuracy is limited because the operator selects a plate cylinder to be used for the plate release at his own discretion. For example, the plate cylinder for the most recent printing work is often diverted, or the one that has a high degree of difficulty in the printing plate work is often diverted. For this reason, extra diversion work is often performed. Therefore, an increase in cost for diversion of the plate cylinder and an increase in the plate work time have been serious problems.
In view of the above points, the present invention provides a plate cylinder falling plate transfer processing apparatus capable of diverting a plate cylinder so as not to cause useless diversion work in consideration of a printing work schedule and difficulty of diversion. This is the issue.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a plate cylinder falling plate diversion processing apparatus according to the present invention. As shown in FIG. 1, the plate cylinder drop processing apparatus according to the present invention includes an input unit 1, an arithmetic processing unit 2, a display unit 3, and a storage unit 4. The input unit 1 has functions for inputting information necessary for processing, instructing processing execution, and the like, and is actually realized by a keyboard, a mouse, and the like. The arithmetic processing means 2 plays a central role of the plate cylinder falling plate diversion processing apparatus, and includes a plate cylinder alignment state calculating means 5, a plate cylinder extracting means 6, and a data updating means 7. The arithmetic processing means 2 is actually realized by a personal computer, a workstation, etc., and the plate cylinder alignment state calculating means 5, the plate cylinder extracting means 6, and the data updating means 7 are equipped with a dedicated program in the personal computer, workstation, etc. It is realized by doing. The display means 3 can display various information and is realized by a CRT display or the like. The storage means 4 stores various information such as information necessary for processing and information generated in the processing process, and is realized by an external storage device such as a hard disk. The storage means 4 is preferably shared with the printing work scheduled terminal and the control means of the printing press via a network.
[0009]
At the start of processing by this apparatus, the storage unit 4 stores at least plate cylinder data, pattern configuration data, and printing work schedule data. These data are input by an operator from the input means 1 or supplied from another system (for example, a printing work scheduled terminal or the like) via a network. FIG. 2 is a diagram showing plate cylinder data. Each item of the plate cylinder data will be described in order from the left side of FIG. The plate cylinder number is assigned for identifying the plate cylinder and is a number unique to all the plate cylinders. The plate cylinder pattern number is a number for identifying a picture printed on the plate cylinder. Since the printing cylinder of the printing cylinder number “C0001” is “1” and the printing cylinder of the printing cylinder number “C0002” is “2”, the printing cylinder of the printing cylinder number “C0001” is printed first. It turns out that it is a thing. The circumference and the plate width indicate the circumference and width of the plate cylinder in [mm (millimeter)] units, respectively. The use category indicates whether the plate cylinder is usable or not usable. Only plate cylinders that are “available” can be used for printing. The diversion category indicates whether the plate cylinder can be diverted. Those that are difficult to press are normally set to “impossible” and are not diverted.
[0010]
FIG. 3 is a diagram showing pattern configuration data. Each item of the pattern composition data will be described in order from the left side of FIG. The pattern configuration number is a unique number for each pattern formed by the plate cylinder. The printing order indicates the printing order for printing having the same pattern configuration. The circumference, width, and plate cylinder number are the same as the circle, plate width, and plate cylinder number in the plate cylinder data shown in FIG. The relationship between the pattern configuration number and the plate cylinder pattern number is shown in FIG. As shown in FIG. 13, for example, when one printing is performed with four plate cylinders, the numbers determined for the patterns of the four plate cylinders are called plate cylinder pattern numbers, and there are four in this case. However, since one pattern is finally printed, the pattern number determined for one printed matter is referred to as a pattern configuration number.
[0011]
FIG. 4 is a diagram illustrating print work schedule data. This print work schedule data is data created by the print work schedule set terminal. Since a printing work schedule group terminal for planning a printing work schedule is well known, description thereof is omitted. Each item of the scheduled print work data will be described in order from the left side of FIG. The print work number is assigned to specify the print work and is a unique number for each print work. The number of sheets input is the number of sheets required for the printing operation, and is shown in [m (meter)] units. The pattern configuration number is the same as the pattern configuration data shown in FIG. 3 and is associated with the print work number here. The scheduled work start date / time and the scheduled work end date / time indicate the scheduled start date / time and scheduled finish date / time of the printing work, respectively.
[0012]
Next, the processing operation of this apparatus will be described using the flowchart of FIG. First, when an instruction to start processing is given from the input means 1 to the arithmetic processing means 2, the plate cylinder alignment status calculation means 5 in Step 1 determines the print work number from the print work schedule data, the pattern composition data, and the plate cylinder data. The state of alignment of the plate cylinders is calculated. In Step 1, first, the configuration information of the pattern configuration data shown in FIG. 3 is obtained using the pattern configuration number of the print work schedule data shown in FIG. Since each plate cylinder pattern number constituting the pattern can be extracted from the configuration information of the pattern configuration data, the corresponding plate cylinder pattern number is used from the plate cylinder data shown in FIG. Check if there is a plate cylinder whose category and diversion category are both acceptable.
[0013]
For example, the case where the plate cylinder alignment state is calculated for the print work number “P0002” in the print work schedule data of FIG. 4 will be described with reference to FIG. The pattern composition number “G002” is extracted from the printing work number “P0002” (the table on the left side of FIG. 6). It can be seen from the pattern configuration data in FIG. 3 that the plate cylinder pattern numbers constituting the pattern configuration number “G002” are “B1” and “B2” (table in the upper right of FIG. 6). When the plate cylinder data shown in FIG. 2 is searched using the plate cylinder numbers “B1” and “B2”, the plate cylinder number “C0003” is extracted for the plate cylinder number “B1” (the table on the lower right of FIG. 6). ). However, for the plate cylinder pattern number “B2”, since there is no corresponding plate cylinder, it is understood that the plate cylinder alignment status of the printing work number “P0002” is not complete. At the same time, plate cylinder shortage information that the plate cylinder of the pattern composition number “G002”, the printing order “2”, the circumference “750”, and the plate cylinder pattern number “B2” is insufficient is obtained.
[0014]
In Step 2, the plate cylinder alignment status calculated in Step 1 is displayed on the display unit 3. When the processing of Step 1 is similarly performed on the print work numbers “P0001” to “P0005” in the print work schedule data shown in FIG. 4, the result shown in FIG. 7 is obtained and displayed on the screen. At this time, the plate cylinder numbers “C0001” to “C0007” necessary for “P0001” to “P0005” are changed to “unusable” in the plate cylinder data, and are secured so that they cannot be used elsewhere.
[0015]
The processing of the next Step 3 to Step 12 is performed by the plate cylinder extracting means 6. When a plate transfer diversion process is instructed on the plate cylinder alignment state confirmation screen shown in FIG. 7, the process of Step 3 is started. In Step 3, a plate cylinder to be diverted is extracted (printed plate diversion process) for a printing work number in which the plate cylinders are not uniform. This is done by extracting from the plate cylinder data those plate cylinders whose usage and diversion categories are both “possible”, those that match the plate cylinders that require the circumference and width of the plate cylinder. . Subsequently, in Step 4, it is checked whether or not the plate cylinder has been extracted. If the plate cylinder cannot be extracted, it is checked in Step 5 whether the limit of the plate cylinder extraction condition has been reached. When the extraction condition has not reached the limit, in Step 6, the extraction condition range is expanded and the plate cylinder is extracted. That is, in Step 3, if a plate cylinder having the same circumference and plate width cannot be extracted, the corresponding plate cylinder is extracted by expanding the circumferential range by ± 1 mm in the loop of Step 4 to Step 6. The extraction condition in Step 5 is set in advance by the operator using the input means 1, and in this example, ± mm of the circumference is set as the limit.
[0016]
For example, a plate cylinder extraction process for a plate cylinder pattern number “B2” that is not aligned with the printing work number “P0002” will be described with reference to FIG. Since the plate cylinder shortage information is obtained from Step 1 (the table on the left side of FIG. 8), the plate cylinder close to this short plate cylinder information is extracted. From the plate cylinder data, “C0008” to “C0012” in which the use classification and the diversion classification are both “possible” are extracted (the first table from the upper right in FIG. 8). Next, as shown in the plate cylinder shortage information, two candidates of the plate cylinders “C0011” and “C0012” having the circumference “745”, the width “1100”, and the same conditions as those required by the plate cylinder pattern number “B2” are candidates. (The second table from the upper right in FIG. 8). In this case, since a plate cylinder having the same extraction condition is found in Step 3, the process proceeds from Step 4 to Step 7.
[0017]
In Step 7, it is checked whether or not a plurality of plate cylinders have been extracted. When a plurality of plate cylinders are extracted, in Step 8, the number of use of plate cylinder data is compared, and the plate cylinder having the maximum number of use is selected. In Step 9, it is checked whether or not a plurality of plate cylinders have been selected even after the processing in Step 8, that is, whether or not there are a plurality of use cylinders having the maximum number. If a plurality of plate cylinders are still extracted, in Step 10, the last use date of the plate cylinder data is compared, and the plate cylinder having the oldest use date is selected.
[0018]
In the example of the printing work number “P0002” in FIG. 8 described above, since two plate cylinders “C0011” and “C0012” have been extracted, the process proceeds from Step 7 to Step 8. When the number of uses is compared in Step 8, both “C0011” and “C0012” are “150,000 m” (the second table from the upper right in FIG. 8), so the two plate cylinders are extracted and the process proceeds from Step 9 to Step 10. . In Step 10, when the last use dates of the two plate cylinders “C0011” and “C0012” are compared (the third table from the upper right in FIG. 8), the last use date is the plate cylinder “C0012”. The trunk “C0012” is extracted (the fourth table from the upper right in FIG. 8).
[0019]
In Step 11, it is further checked whether or not a plurality of plate cylinders are extracted. If a plurality of plate cylinders are still extracted at this time, the operator instructs only one plate cylinder to be extracted at Step 12.
[0020]
In Step 13, the data updating means 7 creates printing plate work schedule data and updates the plate cylinder data for the plate cylinder extracted by only one as a result of determination or processing in Step 7, Step 9, Step 11, and Step 12. FIG. 9 shows the plate work schedule data obtained as a result of performing the above Step 1 to Step 13 for the print work schedule data shown in FIG. As shown in FIG. 9, the printing plate work schedule data indicates what pattern composition number, printing order, plate cylinder pattern number, printing work number, and scheduled use date and time of the extracted plate cylinder. Yes. At this time, the scheduled use date and time corresponds to the scheduled work start date and time in the print work scheduled data.
[0021]
FIG. 10 shows the plate cylinder data in an updated state as a result of performing the above Step 1 to Step 13 for the printing work schedule data shown in FIG. For example, when the plate cylinder “C0012” is registered in the plate work schedule data as shown in FIG. 9, the diversion classification of the plate cylinder “C0012” in the plate cylinder data is updated to “impossible” as shown in FIG. Is done.
[0022]
In Step 14, it is confirmed whether or not the printing plate transfer process has been completed for all the printing work numbers in Step 2 in which the necessary plate cylinders are not prepared. If it is determined in Step 14 that all the processes have been completed, the plate transfer process result is displayed on the display unit 3 in Step 15. FIG. 11 shows the result of displayed plate diversion processing. If it is determined in Step 14 that all the processes have not been completed, in Step 16, the plate cylinder extraction target is changed to an unprocessed print work number, and then the process returns to Step 3 to perform the process.
[0023]
As described above, the printing plate diversion process is performed. If a plate cylinder that satisfies the extraction conditions cannot be extracted in Step 5, the printing plate diversion processing error data is created in Step 17, and then the printing plate printing process is performed. The diversion error result is displayed on the display means 3 (Step 18). FIG. 12 shows the result of the error of diversion that is displayed.
[0024]
The printing plate work schedule data and the updated plate cylinder data obtained by the above processing are stored in the storage means 4, and the subsequent plate cylinder printing plate work is performed using these data.
[0025]
The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above-described embodiment, after the plate cylinder alignment state calculation unit 5 calculates the plate cylinder alignment state, it is displayed on the display unit 3 and the operator issues an execution instruction. On the basis of the result of No. 5, the process may be automatically shifted to the processing of the plate cylinder extracting means 6. For this purpose, it is only necessary that the missing plate cylinder information obtained by the processing of the plate cylinder alignment state calculating unit 5 is passed to the plate cylinder extracting unit 6 as it is.
[0026]
【The invention's effect】
As described above, according to the present invention, according to the present invention, the plate cylinder alignment state is calculated based on the printing work schedule data, the pattern composition data, and the plate cylinder data, and the plate cylinder whose conditions are close to the missing plate cylinder is obtained. Since the plate cylinder is diverted by extracting, it is possible to use the plate without waste considering the printing work schedule.
Also, the plate cylinder alignment status is calculated based on the pattern configuration in the print work schedule data, specifying the plate cylinder pattern from the pattern configuration data, and using the specified plate cylinder pattern to determine the required plate on the plate cylinder data. Since it is confirmed whether or not there is a cylinder, it is possible to easily confirm the state of alignment of the plate cylinders using prepared printing work schedule data.
In addition, the extraction conditions of the plate cylinder are determined according to the conditions and the extraction conditions related to the circumference and width of the plate cylinder. Therefore, it becomes possible to extract the necessary number of optimum plate cylinders.
In addition to this, if the circumference value in the extraction condition by the plate cylinder extracting means has a predetermined range, even if a plate cylinder having the same circumference value is not found, it is possible to extract a near plate cylinder. become.
