[0009]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram showing an embodiment of a paper container designing apparatus according to the present invention. The paper container designing apparatus shown in FIG. 1 includes an input unit 1, an arithmetic unit 2, an output unit 3, a display unit 4, and a storage unit 5. Here, in detail, the calculating means 2 inputs the pitch by using the input means 1 and the group registration means 21 for registering a plurality of paper container shapes as one group by specifying using the input means 1. Intra-group pitch registration means 22 for registering the pitch between the paper container shapes in the registered group, and inter-group pitch registration means for registering the pitch between the registered groups by inputting the pitch using the input means 1 23, a shape arranging means 24 for arranging a paper container shape according to the registered intra-group pitch and inter-group pitch. The storage means 5 has a shape database 51 for registering already designed paper container shapes, and an allocation database 52 for registering output drawings after allocation.

More specifically, the input means 1 is a mouse and a keyboard, and the arithmetic means 2 is constituted by a CPU of a personal computer, a memory, and a program stored in the memory. This is realized by a dedicated program stored in. The output means 3 includes a printer for outputting to paper, a data output device for outputting data for forming a die for punching a paper container, and the like. The display means 4 can be realized by a CRT display, and the storage means 5 can be realized by a hard disk.

FIG. 2 is a flowchart showing the processing operation of the paper container designing apparatus shown in FIG. When the paper container designing apparatus is activated and an instruction to perform allocation is input by the input unit 1, the arithmetic unit 2 calls the paper container stored in the paper container shape database 51, and displays the display unit 4 as shown in FIG.
A plurality of available paper container shapes are displayed on the screen of, and the selection is prompted. Here, the operator uses the input means 1 to select a paper container shape to be arranged. Only one paper container shape can be selected, or a plurality of paper container shapes can be selected.
(Step S1)

When the selection of the paper container shape is completed, the selected paper container shape is displayed on the screen of the display means 4. Here, after moving or rotating the paper container shape on the screen using the input means 1, an instruction to register as a group is issued. FIG. 4 shows a display on the screen in a state registered as a group. At this point, the intra-group pitch, which is the relative positional relationship between the two paper container shapes in the group, is determined. (Step S
2)

When the registration of the group is completed, an initial condition setting screen as shown in FIG. 5 is displayed. As shown in FIG. 5, a dialog box is displayed on the initial setting screen together with a message "Please input the number and interval of array copy" so that the number and interval can be input.
Here, the operator inputs a desired set value using the input unit 1. In the example shown in FIG. 5, a total of six groups are arranged in three columns in the X direction and two rows in the Y direction, and an interval between the groups is set to 8 mm in the X direction and 8 mm in the Y direction. The state is shown. The relative positional relationship between the groups determined by the interval between the groups is the inter-group pitch. (Step S3)

When the user clicks the OK button in the dialog box shown in FIG. 5, the allocation result is displayed on the screen of the display means 4. FIG. 6 shows a state where the layout is made in accordance with the contents initially set in step S3. Two groups of paper container shapes are allocated in three columns in the X direction (horizontal direction) and two rows in the Y direction (vertical direction). ing. (Step S
4)

Here, the operator checks the allocation result by looking at the screen, and if there is no problem, issues an output instruction and outputs the allocation result to the output means 3. (Steps S5 and S6) Thereafter, the calculating means 2 stores the allocation result as graphic data in the allocation database 52 of the storage means 5. (Step S7)

In confirming the allocation result in step S5,
If the operator determines that correction is necessary, the operator selects a pitch adjustment method. There are two types of pitch adjustment methods: adjustment of the pitch within a group and adjustment of the pitch between groups. In the screen where the assignment result is displayed,
Icons indicating these two types are displayed (not shown), and by clicking these icons, the adjustment method can be selected. (Step S8)

When the adjustment of the pitch in the group is selected in step S8, two points in the same group for setting the pitch are designated. For example, the operator selects an arbitrary point E2 on the outline of the paper container shape F2, and then selects an arbitrary point E1 on the outline of the paper container shape F1 in the same group. When two points are selected, a line is drawn between E1 and E2 as shown in FIG. The line segment E1-E2 is distinguished from the color of the outer shape of the paper container shape so as to be conspicuous. (Step S9)

When the line between E1 and E2 is drawn, a dialog box for setting the pitch is displayed on the display screen as shown in FIG. At this time, the X-direction and Y-direction columns C1 and C2 show the X-direction and Y-direction relative distances from the point E1 to the point E2, respectively. FIG.
In the case of the example, since the X coordinate and the Y coordinate are larger in E2 than in E1, a positive (plus) numerical value is entered. In step S9, if E2 is specified after E1 is specified, a negative (minus) numerical value is entered. In the distance column C3, the current length of the line segment E1-E2 is displayed. In this dialog box, two types of designation methods can be selected. When the operator designates "change the values in the X and Y directions", X in the dialog box is displayed.
The movement values in the direction and the Y direction can be input to the columns C1 and C2, respectively. On the other hand, when "change distance between two points" is selected, the value of "distance" below it can be input.
Below the input of the value, there is a check box as to whether or not “reflect the pitch change to another group”, and by checking this, it becomes possible to reflect the pitch change to another group. (Step S10)

When the button of rearrangement is clicked in the dialog box shown in FIG. 8, the shape arranging means 24 confirms whether "Reflect pitch change to another group" is checked in step S10. (Step S11)

"Reflect pitch change to other groups"
Is checked, the shape arranging means 24 performs a process of changing the pitch within the entire group as shown in FIG. (Step S12)

If it is determined in step S10 that the change in pitch is not reflected in another group, the shape arranging means 24 determines only the pitch in the group including the paper container shape specified in step S9 as shown in FIG. Perform the change process. (Step S13)

Regarding the moving direction in steps S12 and S13, when drawing a line in step S9, the paper container shape specified later is fixed, and the paper container shape specified earlier is moved. In this example, a point E on the outline of the paper container shape F2
Since 2 is specified first, the position of the paper container shape F1 is fixed, and the paper container shape F2 moves. Therefore,
If “change values in X and Y directions” is specified in step S10, the calculating means 2 returns to the original columns C1 and C2.
The difference between the value of 2 and the values of the input columns C1 and C2 is calculated, and the paper container shape F2 moves in the X and Y directions by the calculated difference. When “change distance between two points” is specified, the calculating means 2 returns to the original column C3
Is calculated and the value of the input column C3 is calculated, and the paper container shape F2 moves in the direction along the line segment E1-E2 with respect to the paper container shape F1 by the calculated difference.

On the other hand, when the adjustment of the pitch between groups is selected in step S8, an arbitrary point of the outer shape of the paper container shape in one group and another point on the screen in which the figures are allocated as shown in FIG. An arbitrary point on the outer shape of the paper container shape of the group is designated. For example, after specifying the point E4 on the outline of the paper container shape F3, the paper container shape F2 of another group is specified.
If a point E3 on the outline is designated, a line segment E3-E4 is drawn as shown in FIG. (Step S14)

When the line segment E3-E4 is drawn, a dialog box similar to that shown in FIG. 8 is displayed in the same manner as when the in-group pitch is specified in step S10, and prompts an input from the operator. (Step S15)

When the rearrangement button is clicked after the input, the shape arranging means 24 confirms whether "Reflect pitch change to other groups" is checked in step S15. (Step S16)

"Reflect pitch change to other groups"
Is checked, the shape arranging means 24 returns to FIG.
A process of changing the pitch within the entire group is performed as shown in FIG. (Step S17)

If it is determined in step S15 that the change in pitch is not reflected in other groups, the shape arranging means 24 determines only the inter-group pitch of the group including the paper container shape specified in step S14 as shown in FIG. Perform the change process. (Step S18)

Steps S12, S13, S17, S18
The graphic data rearranged by the shape arrangement means 24 in
It is displayed on the screen of the display means 4. (Step S4)

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. For example, in the present embodiment, a mode using a stand-alone personal computer has been described. However, the storage means 5 is a large-capacity data server, and the input means 1, the arithmetic means 2, the output means 3, and the display means 4 A plurality of terminals may be connected as client machines. Also, in the present embodiment, two types of figures are
Registered as one group, but three or more types
It is also possible to register as one group, and it is also possible to register two or more types of graphics as one group.

[0030]

According to the present invention, after a plurality of shapes are grouped and registered, the pitch between the shapes in the registered group is set, and the pitch between the groups is set. Since the shapes are arranged based on the pitch, it is possible to easily allocate a plurality of types of paper containers in the group with the same paper.

Further, the pitch is set by designating one point on the outer shape of the paper container shape adjacent to one point on the outer shape line of the paper container shape, and specifying the distance between the two specified points. In addition, it is possible to set a minimum margin so that the paper container shapes do not overlap.
