Next, the operation of the printing machine operation schedule planning system will be described with reference to the flow charts of FIGS. FIG. 9 is a flowchart for explaining the outline of schedule planning. The item data sent from the host system 50 and stored in the item data file 115 is read by the data read / write means 101 (step 901). at the same time,
A plurality of printing machines P1 to P from the registration data file 120
The registration data (specification data 600, processing capacity data 700, suspension schedule data 800) relating to j is read by the data read / write means 101 (step 902).
As shown in FIG. 3, each read item data is individually given a continuous ID number, and thereafter managed by this ID number.

With respect to the read item data, a printing margin defined by (delivery date-planned planning day) / number of sheets is calculated by the printing margin calculating means 106 for each item (step 9).
03). Then, the data sorting means 102 sorts the calculated printing margins in ascending order (step 9).
04). The sorted item data are assigned to the printing machines P1 to Pj having the specifications in order from the item with the smallest printing margin (step 905). When there are a plurality of printing machines that meet the specifications, the printing machine with the smallest load is selected and allocated. Schedule data is generated by the allocation to the printing machines P1 to Pj and stored in the schedule data file 130 (step 906). Also,
The schedule data that has been allocated to the printing machine is displayed as a schedule on the display device 141, and is printed out by the printer 142 as necessary.

Details of the allocation processing in step 905 are shown in the flowchart of FIG. First, the allocation according to the size is performed (step 1001). This is a process of allocating each item to a printing machine having a compatible size by collating the size of the item data with the size of the size recorded in the specification data of each printing machine. Next, allocation is performed according to the number of colors (step 1002). This is a process of assigning each item to a printing machine having a matching number of colors by collating the number of colors of item data with the number of colors of specification data of each printing machine.

The scheduled print start date and time for each item is calculated based on the allocation status of each printing machine, the scheduled operation stop data 800 of the registration data file 120, and the scheduled completion date of plate making for each allocated item (step). 10
03). The scheduled finish date of the plate making is taken into consideration because the actual printing cannot be performed unless the plate making for printing the item is completed.

Next, the scheduled print end date and time for each item is calculated based on the allocation status of each printing machine, the data 700 indicating the processing capacity of the registration data file 120, and the scheduled operation stop data 800 (step 1004). ). The schedule data is generated as described above, and the schedule is displayed on the screen of the display device 141 based on the schedule data (step 1005). After that, the control means 107 checks whether or not the scheduled data of each item is allocated within the delivery date (step 1006). If the delivery condition is satisfied, the allocation process is terminated.

Each item data is transferred to a plurality of printing machines P1 to Pj.
13 to 16 show the structure of the schedule data generated by allocating to the. The schedule data includes allocation data, item data and related data of allocation data, scheduled print start date / time data, and scheduled print end date / time data.

FIG. 13 shows allocation data generated by the allocation process. Here, it is recorded which printing machine and which number is assigned to each item identified by the ID number. FIG. 14 is data showing a relation between the item data and the allocation data shown in FIG. 13, and shows which item data (ID number) is allocated to each printing machine P1 to Pj.

Further, FIG. 15 shows data in which the scheduled print start date and time obtained in step 1003 of FIG. 10 is recorded for each allocation order in each printing machine. FIG. 16 shows data in which the scheduled printing end date and time obtained in step 1004 of FIG. 10 is recorded for each allocation order in each printing machine. In FIG. 17,
The screen image of the schedule 160 displayed in step 1005 is shown. Here, the time axis of the date and time is taken vertically for each printing machine, and the ID numbers of the allocated item data are displayed as the display band 170 in the allocation order. In addition,
The size (height) of the display band 170 corresponds to the time required for the printing process. As will be described later, the display band 170 of each item displays the order number, the content code, the component parts, the division history, etc. of the item data, and by visually observing the display band 170, it is determined which item the data is. I'm trying to understand. In the step 1006, when the delivery date of the specific item is overdue, a warning of delivery delay is displayed on the schedule displayed on the display device 141 to call attention (step 1007). In this case, the allocation is changed by dividing the number of items or the number of colors, which will be described later (step 1008). This allocation change is repeated until the delivery date condition is satisfied.

Next, the processing of the schedule display control means 111 for displaying the contents of the schedule data generated as described above on the display device 141 as the schedule table 160 will be described with reference to FIGS. When the schedule display control unit 111 loads the generated schedule data (step 1801), the schedule display control unit 111 refers to the allocation data of the schedule data, the related data of the item data and the allocation data, the scheduled print start date / time data, and the scheduled print end date / time data, The size of the display band 170 representing the allocated item data is determined in correspondence with the print processing time required for the item (step 1802).

Then, in accordance with the size of the display band 170 determined as described above, the display information regarding the items displayed on the display band 170 is selected according to a predetermined priority order (step 1803). This display information is selected from the information included in the item data shown in FIG. For example,
The display information includes the order number of the item data, the content code, the component, the size, the printing surface, the number of printed sheets, and the name of the customer. In step 1803, display information that can be displayed in the display band 170 is selected from these display information.

The display band 170 for which the display size and the display information are obtained as described above is made to correspond to the allocation data of the planned data and the related data of the item data and the allocation data in correspondence with the time axis allocated for each printing machine. Based on this, the images are displayed on the display device 141 in a predetermined order in the state as shown in FIG. 17 (step 1804). In this case, as shown in the drawing, the schedule for 2-3 days is displayed on one screen of the display device 141. However, the number of days that can be displayed on one screen can be freely selected. For example, when confirming the rough allocation state, many days are selected on one screen, and when confirming in detail, few days are selected.

FIG. 19 shows a display example of the display information selected according to the size of the display band 170. As shown in FIG. 19, when the size of the display band 170 is sufficiently large and all the above-mentioned display information can be displayed, the order number and the content code 171 (the order number and the content code are "-") of the item data.
(Separated by 1 line), component 172, size and printing surface 173 (size and printing surface are shown in 1 line), number of prints 174, number of front surface colors and number of back surface colors 17
5 (the front side color number and the back side color number are separated by "/") and all the display information of the customer name 176 are selected and displayed in the order shown. On the other hand, the small display band 17
For 0, it is not possible to display all of the above display information, so the number of pieces of information that can be displayed in that size is selected. This selection is made by selecting the order number and content code information 171, the component information 172, the size and the printing surface 1 of the item data.
73, the number of printed sheets 174, the number of front surface colors and the number of back surface colors 175, and the customer name 176 are selected in accordance with the priority order. For example, in FIG. 19, only the order number, the content code 171, and the component 172 are displayed on the display band 170 having a small size. Note that the display example shown in FIG. 19 is merely an example, and information other than the above item data may be displayed on the display band 170.

Further, when the schedule table 160 is displayed in step 1804, the schedule display control means 111 color-codes a part of the display information displayed on the corresponding display band 170 according to the size of the item. indicate. This color coding is performed by changing the back color of the display information, for example, the content code. For example, when there are 6 sizes in size, the colors used for color coding are designated in order from the item with the largest size, such as magenta, red, orange, yellow, green, cyan, or the like. In the display example of FIG. 19, the part enclosed by the square of the order number and the content code of the content code 171 is displayed in different colors.

By the color-coded display according to the size,
When confirming the contents of the schedule displayed on the screen of the display device 141, the operator can check the size of the item only by looking at the color coding of the display band 170 showing each item assigned to each schedule. Can be recognized. Note that the display information to be color-coded does not have to be the content code portion as described above, and may be other display information. However, if the order number with the first priority and a part of the content code 171 are set to be color-coded, it is convenient because they are always displayed even when the size of the display band 170 is small.

Next, with respect to the scroll processing of the schedule 160 up and down and left and right by the schedule display control means 111,
This will be described with reference to FIG. In this device, the schedule table 160 displayed on the screen of the display device 141 is displayed by the mouse 1
It is possible to easily scroll up and down and left and right by a drag operation with 52.

The schedule display control means 111 includes a mouse 152.
It is determined whether or not the pointer is located on the four sides of the screen (step 2001). If the pointer is located on the four sides of the screen, it is determined whether the position is the upper side or the lower side, or the left side or the right side (step 2002). When the pointer position of the mouse 152 is on the upper side, the schedule is specified to scroll downward in the screen, so whether the date and time after the date and time displayed for the schedule 160 displayed on the screen is the schedule planning period. If the pointer position is on the lower side, the schedule is specified to scroll upward in the screen. Therefore, whether the date and time before the date and time displayed for the schedule 160 displayed on the screen is the schedule planning period. It is determined (step 2003).

When the pointer of the mouse 152 is located on the upper side of the screen, scrolling downward is specified.
When the scheduled date and time after the displayed date and time are the schedule planning period, the schedule table 160 on the screen of the display device 141 is scrolled downward, and the scroll is designated in the upward direction where the pointer is located on the lower side of the screen. On the other hand, when the scheduled date and time before the displayed date and time is the planning target period, the display device 1
The schedule table 160 on the screen 41 is scrolled upward (step 2004). In either case, while the pointer of the mouse 152 is positioned on the upper side or the lower side, scrolling continues if the displayed date and time is the schedule planning period.

When the pointer position of the mouse 152 is on the right side or the left side, the schedule is specified to be scrolled to the left or right of the screen, so that it is not displayed on the right or left side of the schedule 160 displayed on the screen. It is determined whether there is a printing machine (step 2005).

If the pointer position of the mouse 152 is on the right side and there is an undisplayed printing machine on the right side of the schedule table 160, the schedule table 160 on the screen of the display device 141 is scrolled to the left, and the mouse 152 If the pointer position is on the left side and there is a printing machine not displayed on the left side of the schedule 160, the schedule 160 on the screen of the display device 141 is scrolled to the right (step 2004). In any case, while the pointer of the mouse 152 is located on the right side or the left side, scrolling is continued until there are no unprinted printing machines. By the operation of positioning the pointer of the mouse 152 on the four sides of the screen, the schedule 160 can be easily scrolled up, down, left, and right to display the schedule of the undisplayed date and time and the schedule of the undisplayed printing machine.

Regarding the warning in step 1007 of FIG. 10, for example, by changing the back color of the order number displayed on the display band 170 of each item of the schedule shown in the images of FIGS. 17 and 19. , Make it easy to check which item is overdue.

Next, the processing contents of the allocation change of step 1008 in the allocation processing shown in FIG. 10 will be described with reference to FIG. First, it is selected whether the item data that does not meet the delivery date condition is divided by the number of sheets or the number of colors (step 1101). Each item data is divided based on the number of sheets or the number of colors according to the selection of the dividing method (steps 1102 and 1104). And
To the new item data obtained by division, history information is added to the division history shown in FIG. 3 so that it can be identified that they have a sibling relationship with each other.

FIG. 21 shows an example in which the item data shown in FIG. 4 is divided by the number of sheets and the number of colors. Here, the number of colors is 6
Components of content code 01 (cover) that is color (1/1)
Is divided into two by the number of colors. The division information of C1 and C2 is added to the division history. Content code 0
The first component (1/3) of 2 (text) is divided into two by the number of sheets. The division information of L1 and L2 is added to the division history.

Further, FIG. 22 shows how the item data of FIG. 5 is changed by the division of FIG. Here, two item data are newly added and inserted by division, and ID numbers (numbers 1 and 3) are added. When new item data is inserted, the ID numbers after that are automatically updated and become continuous ID numbers. With respect to the item data of ID numbers 0 and 1, history information C1 and C2 indicating that the number of colors is divided is added to the division history, and the sibling relationship is designated. Further, the number of colors is 6 colors in the original item data of FIG. 5, but is divided into 4 colors and 2 colors. For item data of ID numbers 2 and 3,
History information L1 and L2 indicating that the lot is divided is added to the division history, and the sibling relationship is designated. Further, the number of sheets is 2000 in the original item data of FIG. 5, but is divided into 1500 and 500.

The divided item data (for example, ID numbers 0 and 1 and ID numbers 2 and 3 in FIG. 22) are assigned to a printing machine conforming to the specifications (steps 1103 and 110).
5). This allocation is performed by the above-mentioned printing machines P1 to Pj.
It is done with reference to the registration data of. Also, the divided item data can be assigned automatically,
It is also possible to perform it manually by the operation of the operator. When manually allocating, by specifying the divided item data by clicking with the mouse 152 on the screen of the schedule displayed as shown in FIG. 17, and by specifying the allocation destination with the mouse 152. To do.

For the item data divided by the number of colors, it may be predetermined which color is to be printed first. For example, if the order is determined such that yellow, magenta, indigo, and black are printed first, and then other special colors (eg, gold, silver, etc.) are printed, the colors are divided by color. The control means 107 checks whether or not the item data is assigned according to a predetermined order (step 1106). For example, when the spot color item data is assigned earlier in time, a warning indicating that the order is wrong is issued. This warning is given by changing the color of the display band of the corresponding item data on the display screen of the calendar. If the order is different, the allocation is performed again so that the order is predetermined (step 1107).

When the above item data is divided by the number of sheets or the number of colors and the allocation change is completed, it is checked again in step 1006 in FIG. 10 whether each item data satisfies the delivery date. If satisfied, the allocation is complete. If not satisfied, the allocation changing process by division is repeated. In addition to such delivery date handling, of course, the number of colors is divided for items that exceed the machine's color number limit.

Next, the process for synthesizing the divided item data is shown in the flowchart of FIG. When combining the once divided item data for reasons such as schedule change, first, the divided item data is designated (step 120).
1). This designation is made by clicking the item data display band 170 with the mouse 152 on the display screen of the schedule shown in FIG. By specifying the item data, the history information recorded in the division history is read (step 1202). Then, based on the read history information of division, it is determined whether or not division data exists (step 1203). If the divided item data does not exist, it indicates that the item data specified first is incorrect, and the process ends.

If there is item data that has been divided,
The item data is rewritten based on the division history information and combined (step 1204). For example, in the item data of FIG. 22, the item data of ID numbers 0 and 1 and the item data of ID numbers 2 and 3 are combined to obtain the content of FIG. When the divided item data is combined, the original divided data is deleted, and the combined item data is allocated (step 1205).

FIG. 23 shows an example of a screen display when confirming and editing item data. Here, an example is shown in which the window 200 for displaying the contents of the item data is displayed overlapping the schedule table by designating the display band 170 of the specific item on the schedule display screen of FIG. ing. On this screen, as shown in the figure, the content of the data regarding the item is divided into a plurality of item names 201 and displayed. With this display, the detailed contents of each item data can be confirmed.
