Description

Description: BACKGROUND OF THE INVENTION [0001] The present invention relates to a paper container design system, and more particularly to a paper container design system in which processing such as enlargement and reduction can be performed by interruption even during drawing processing.

[Prior Art] CAD systems are widely used for graphic processing, and the basic configuration is as shown in FIG. In the figure, 230 is a processing device, 2
31 is an input device, 232 is a storage device, 234 is a display device, and 235 is an output device. Now, assuming that the operator inputs data of the position and radius of the center point from the input device 231 to draw a circle, the processing device 230 calls up necessary information from the database of the storage device 232 and, for example, a display device including a CRT. Draw the circle specified at 234. When a desired figure is completed by continuing such operations, the figure is dimensioned and output to an output device 235 such as an XY plotter.

In this way, a desired figure can be created while interacting with the display device 234.

[Problems to be Solved by the Invention] When performing drawing, there are cases where the drawing processing is difficult due to the fine figures. In such a case, the drawing is performed by enlarging a part of the figure. However, in the case of the related art, it is necessary to end the drawing process once and then perform the enlarging process, which is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problem, and an object of the present invention is to provide a paper container designing system in which processing such as enlargement can be performed by interruption while continuing drawing processing.

Means for Solving the Problems In order to achieve the above object, a paper container design system according to the present invention is a paper container design system including input means, drawing function means, and display means, wherein the input means At least a key for selecting a desired process, an enlarged interrupt key for enlarging and displaying a designated area, an interrupt key for terminating the enlarged interrupt process, and an area on the screen of the display means. When the enlargement interrupt key is selected by the input means and an area on the screen of the display means is designated, the drawing function means temporarily interrupts the processing being executed and The graphic in the specified area is displayed in an enlarged scale, and if a process to be executed in that state is selected, the process is executed and an interrupt key for terminating the enlarged interrupt process is displayed. When "-" is selected, the figure that has been enlarged and displayed is returned to its original size.

[Operation] According to the present invention, when an enlargement process is desired to be performed in a certain drawing process, if an enlargement interrupt is selected from the input unit, an interrupt process is performed and a desired area of the graphic can be enlarged and displayed. Desired processing can be performed in that state.

[Embodiment] The present paper container design system will be described below, but the description will be divided into the following items for easy understanding.

(I) Explanation of terms (II) Overall configuration and flow (III) Design of paper container (III-1) Design based on basic pattern (III-2) Design based on combination of parts (III-3) Design based on parts connection (III- 4) Design by drawing (III-4-1) Determination of figures (III-4-2) Interruption processing (III-5) Mutual movement between design means (III-6) Automatic scale (IV) Assignment (IV- 1) Interactive Assignment (IV-2) Automatic Assignment (V) Input Guide (I) Explanation of Terms Hereinafter, an embodiment of a paper container designing system according to the present invention will be described by taking as an example a case of designing a paper container and creating an allocation drawing. However, before that, the names and various patterns of each part of the paper container used in the following description will be described.
As shown in FIG. 1, the main body 1 is composed of several panels (four in FIG. 1). The names of the panels are the first panel and the second panel from the left with the margin 8 left. One side of the body 1 has a lid 6 and a flap 7 and the other side has a bottom 9 forming the bottom part of the box. The lid 6 is roughly divided into two parts depending on the presence or absence of the pawl 10. The pawl is formed by making a small cut from both sides of the lid so that the lid is not easily opened. FIG. 1A shows the case where the pawl 10 is present, and FIG. 1B shows the case where there is no pawl. Step drop 11 is a correction value when sheets are overlapped. In FIG. 1, a solid line (commonly referred to as “all cut”) is a line for cutting a paper container, a broken line (commonly referred to as “scribing”) is a line for folding a paper container, and a dashed line (commonly referred to as a “sewing machine blade”) is a folded paper container. The two-dot chain line (commonly referred to as a "half-cut blade") for weakening the later return is a line for weaving the paper container with a weaker force than the pressing rule. The line separating the main body 1 from the bottom 9 in FIG. 1 does not apply to any of the above-mentioned lines, but this is because such a line is cut off or creased depending on the size of each panel, so this is displayed. Things.

The paper containers are divided into patterns according to how one paper container form is formed, and some examples are shown in FIG. In the drawing, a straight sack refers to a paper container form in which the lid of the paper container is located at the same position above and below the main body. The reverse sack refers to a paper container configuration in which the lids of the paper containers are at alternate positions on the main body. The auto bottom means a paper container form in which the bottom of the paper container is automatically assembled automatically. The assembling box does not constitute one paper container with one figure, but means a form in which one paper container is composed of two or more shapes. The four corner sticking is a paper container form in which four flaps are glued and assembled automatically mechanically. The seal carton refers to a paper container form in which flaps are glued to improve airtightness.

(II) Overall Configuration and Flow FIG. 3 shows the overall configuration of one embodiment of the paper container design system according to the present invention. 12 is a processing device, 13 is a color scanner, 14 is a tablet, 15 is a graphic display, 16 is an XY plotter, 17 is a cutting plotter, 18 is a color printer, and 19 is a storage device. The processing device 12 performs various arithmetic processes necessary for generating a graphic. The paper container design system not only creates a development plan and a layout drawing for the paper container design as described later, but also displays various menus and messages for efficient operation of the operator. Or an interrupt process is performed as appropriate, and these processes are also performed by this processing device. The color scanner 13 is provided to take in a picture to be attached to a paper container as image data, and to superimpose the picture on a developed view on the graphic display 15 so that the picture can be corrected. The tablet 14 is input means for inputting necessary data according to input guidance displayed on the graphic display 15. The input means is not limited to a tablet, but may be a digitizer, a mouse, a light pen, or the like. The graphic display 5 is a part of an interface for displaying input procedure guidance, input results, and generated graphics. The XY plotter 16 outputs the designed result as drawing data. The cutting plotter 17 cuts the paper according to the designed result, and assembles it into a desired shape,
It can be determined whether a paper container of a size can be obtained. The color printer 18 outputs a pattern in which a pattern is added to a developed view, and it is possible to determine whether a desired pattern can be obtained by cutting out and assembling the output. The storage device 19 stores various data such as data necessary for performing design, data necessary for generating graphics, and data of design results.

Next, FIG. 4 shows the overall flow of the paper container design. The design of a paper container is not limited to the development of a development diagram, but the present paper container design system provides the following four design means for that purpose.

Basic pattern design Design by component combination Design by component connection Design by drawing Therefore, the overall flow of the design is to first specify the design method (Process 20), perform the design by that method (Process 22), and The flow is to register (process 23). If it is determined in the process 21 that the design means is not specified, the design is completed. The loop returning from the processes 22 and 23 to the process 20 is for allowing modification or change by another design means during the design or after the design is once completed.

(III) Design of Paper Container The above-described four types of design means will be described.

In order to design a paper container, it is necessary that the storage device 18 stores at least data as shown in FIG.

(III-1) Design using basic pattern This is the simplest design method, and the operator is required to
The basic pattern of the developed view stored in FIG.
) Can be designed simply by selecting a desired basic pattern from the items) and inputting the necessary dimensional values. In other words, since the basic pattern is completed as a developed view, only the dimensions need to be included. As the basic pattern, a frequently used pattern may be selected empirically from among the paperboard patterns, and what kind of pattern is used as the basic pattern is arbitrary. For example, the following can be selected as the basic pattern. Straight sack 4 shape, reverse sack 4 shape, auto bottom 12 shape, assembly box lid 1 shape, assembly box 1 shape, cardboard gift box 1 shape, tray former 1 shape, side pasting assembly box 1 shape, sleeve 1 shape, partition 21 Shape, L carton 7 shape.

FIG. 6 is a block diagram, FIG. 7 is a flowchart,
FIG. 8 shows a display screen on the graphic display 15.

When the design based on the basic pattern is selected by key input, a menu fixedly displayed on the tablet or other appropriate input means in the process 20 of FIG.
Calls the initial screen of this processing from the storage device 35 and displays it on the display device 34. FIG. 8a shows an example of the screen. The display screen is divided into a work area and other message areas, and the message area is further divided into several areas. As can be seen from FIG. 8a, the names of the patterns selected as the basic patterns are arranged on the initial screen, and the operator selects a desired basic pattern from these using the input device 33 (process 37 in FIG. 7). . In the lower right message area, "shape design basic pattern" is displayed, indicating that the design currently being performed is performed by the design means using the basic pattern. Now, assuming that a direct sack is selected from the basic patterns, the paper container pattern selecting means 25 of the information extracting means 24 calls the selected direct sack pattern from the storage device 35 and displays it on the display device 34. This process is performed under the control of the arithmetic unit 32. FIG. 8b shows an example of the screen. In this example, only two basic patterns of the direct sack are selected, but as described above, any number of basic patterns can be used. Note that the two basic patterns shown in FIG. 8B have different numbers of panels with lids. On this screen, the operator selects a figure to be used from the input device 33 (process 38 in FIG. 7). If the operator selects the upper left pattern, the paper container shape selecting means 26 stores the selected pattern under the control of the arithmetic unit 32 in the storage device.
Called from 35 and displayed on the display device 34. Example 8
As shown in FIG. The selected pattern is displayed in the work area of the screen, and a predetermined message is displayed in the upper message area, in this case, a list of papers used for manufacturing the paper container is displayed, and the operator selects a paper from these. (FIG. 7, process 39). Next, although the display screen is not shown, the presence or absence of the jamming is selected in the process 40. When this process is completed, the screen changes as shown in FIG. 8d. In the work area on the screen, the location where the dimensions should be inserted and the dimension line are displayed along with the selected pattern, the selected basic pattern is displayed in the upper right message area, the list of parameters is displayed in the message area below it, and the list of parameters in the lower row A message requesting input of a dimension value is displayed in the message area.

Although ten parameters A to H, R1, and H1 are displayed in the parameter list, the operator actually inputs nine parameters A to H and R1. H1 is a value that is automatically determined by the sheet and does not need to be input by the operator, but is displayed to inform the operator that there is a value that is determined by the sheet of H1. Although not distinguishable on the drawing, H1 is displayed in a different color from the other parameters on the actual screen. The same applies to H1 and H2 appearing in the parameter list on the screen below.

The operator sequentially inputs parameters according to the guidance of the input position (FIG. 7, process 40). This data is input to the necessary information input means 30 by the input device 33.

In the present paper container design system, the input of the parameters (dimensions) is specially devised in order to reduce the burden on the operator. For example, to make a straight sack, the dimensions shown in Fig. 9 are required,
In the paper container design system, it is not necessary to input all the dimensions of the drawing. In other words, some of the dimensions must be entered by the operator, those determined by calculation from the entered dimensions, those that are automatically determined when the paper container pattern is determined, and those that are automatically determined when the paper to be used is determined. It is empirically known that there are four types of parameters to be determined. Therefore, based on this empirical rule, the number of parameters to be input by the operator is to be minimized. In the example of the shape shown in FIG. 9, the operator inputs only the eight parameters A, B, C, D, E, F, G, and H, whereby G + 2, E + 5 are automatically set. Is calculated. Note that G + 2 means that 2 mm is added to the value of G, and similarly, E + 5 means that 5 mm is added to the value of E. When the paper is selected, the values of a and b are automatically obtained from the basis weight of the paper (expressed in g / m ² or the size of the paper in kg), and B-a and B-b are calculated. Is calculated. Seventh
Selecting the paper in the process 39 in the figure had the meaning of determining the value automatically determined by the paper in this manner. Other angles such as 11 °, 15 °, 30 ° and
The dimensions of the arcs such as 1R (this means an arc having a radius of 1 mm; the same applies hereinafter) and 3R are values specific to the pattern of the straight sack shown in FIG. 9 and do not depend on the dimensions A to H. is there.

In FIG. 9, the radius of the corner roundness of the lid is automatically calculated to be (E + 5) mm by inputting the parameter E, whereas in FIG. 8 d, the radius R1 of the same portion is input by the operator. You have to do it. This is due to the difference in the pattern shape. The shape shown in FIG. 9 is automatically calculated, but the shape shown in FIG. 8e requires input by an operator.

The same applies to patterns other than the straight sack, and parameters that are automatically determined for each pattern are defined.
Values specific to these papers or to the paperboard pattern are stored in the storage device 35 (fourth item in FIG. 5,
Fifth item), when the operator selects a sheet and a paper container pattern, the necessary information extracting means 27 calls a predetermined unique value from the storage device 35 and stores it in the fixed information setting means 29. The arithmetic unit 32 is configured to select a pattern selected based on the data from the three units of the fixed information setting unit 29, the necessary information input unit 30, and the information combination unit 31 that combines the data stored in these two units. All dimensions of are determined.

Since the number of patterns to be input is minimized in this way, the burden on the operator can be reduced,
Thus, work efficiency can be improved.

Further, in the paper container designing system, every time an operator inputs a parameter, an echo is returned from a corresponding position in the parameter list, and it can be confirmed that the parameter has been input. Specifically, when the parameter A is input, the input dimension value is displayed in the parameter A column in the parameter list, and this is an echo. The display of the echo may be performed by any other appropriate method.

When all parameters have been input, the arithmetic unit 32 generates a figure based on the figure generation data (the seventh item in FIG. 5) stored in the storage unit 35 (FIG. 7 process).
41). In the example of FIG. 9, this figure is generated by generating points, line segments, etc. from the lower left reference point O. For example, the line segment l ₁ can be generated by drawing a solid line from the point P ₁ (D + A + B−b, C−H) to the point P ₂ (D + A + B + A + b, C−H). When the generation of the figure is completed, the dimension line and the dimension position are generated by obtaining the dimension line and the dimension position from the relation of the points obtained at the time of the figure generation (process 4).
2). When this process is completed, the created graphic is registered in the common table in the storage device 35 (process 42 in FIG. 7), and the design is completed. The pattern generated in the process 41 of FIG. 7 is displayed in the work area on the screen as shown in FIG. 8e. Obviously, the dimensions of the pattern correspond to the input dimensions.

When the design of the paper container shape is completed as described above, the shape can be confirmed by outputting to the output device 36 such as a cutting plotter (17 in FIG. 3).

In the above example, the straight sack was taken up. However, if the other paper container pattern is also selected as the basic pattern, it is only necessary to select the paper container pattern and paper in the same manner, and to input predetermined parameters. We can do paper container design.

As is apparent from the above description, according to the design based on the basic pattern, even an operator who is not familiar with the paper container design system can design the paper container very easily.

(III-2) Design by Combination of Parts This means is to make a paper container by dividing a paper container into a main body, a lid, a flap, a bottom and the like, and selecting and combining shapes desired to be used from each.
Of course, if all possible paper container shapes are registered as basic patterns, it can be designed simply by inputting dimensions by the above-mentioned basic pattern design means, but the shape of the paper container includes a slight difference in small parts. For example, the number of combinations becomes enormous, and if all of them are used as basic patterns, there is a problem in terms of storage capacity, and selecting a desired pattern is very troublesome and is not a good idea.
Therefore, in this paper container design system, only patterns that are frequently used are used as basic patterns, and if these basic patterns are not enough, for example, if you want to make the shape of the lid or flap different from the basic pattern, prepare it in advance. Thus, a desired shape can be selected and combined from the respective parts. Specifically, taking the straight sack as an example, the straight sack pattern of FIG.
As shown in c and d, the main body, the lid and the flap are divided into three parts, a desired shape is selected from each part, and these are combined. In this design based on the combination of parts, the combination of parts is automatically performed, so that the operator does not need to perform a troublesome work of attaching the parts here and here. In other words, in this design means, if the shape of the paper container is specified, the information that the parts such as the lid and the flap are combined in which position and in which direction is given in advance. In Figure 10, the lid
I and II are respectively I and II and I 'and II' of the main body, and
III, IV of the flap are III, IV, III ', I of the main body, respectively.
V ', III ", IV", and III, IV are connected (item 10 in FIG. 5).

How to set the number of parts for the paper container shape is arbitrary.

Hereinafter, the design of the paper container by this means will be described with reference to the block diagram of FIG. 11, the flowchart of FIG. 12, and the example of the display screen of FIG.

When the design based on the combination of parts is selected in the process 20 of FIG. 2, the arithmetic unit 60 calls the initial screen of FIG. 13A from the storage unit 63 and displays it on the display unit 62. When the operator selects a desired paper container form, for example, a straight sack, using the input device 61 (process 65), the paper container pattern selecting means 51 of the information extracting means 50 refers to the table of the storage device 63 to produce the selected paper container. Determine the type and number of necessary parts (No. 5
(Figure 9 item). Next, the pattern of the selected straight sack is displayed on the screen as shown in FIG. 13b. Therefore, the operator selects a shape to be designed using the input device 61 (process 66). Then, the paper container shape selecting means 52 takes out the selected straight sack pattern from the storage device 63. Assuming that the upper left pattern in FIG. 13B is selected, the screen display changes as shown in FIG. 13C, and a selection of the basis weight is requested, so that the operator selects the basis weight (process 67).

Note that, despite the fact that what is described here is a design based on a combination of components, the "basic design basic pattern" is located at the lower right of FIG. 13c for the following reason. Later "(III-
5) Mutual movement between design means ", the design based on the basic pattern and the design based on the combination of parts are entered in one way and can be separated separately thereafter. Because it is treated as one. However, it is clear that "shape design part combination" may be displayed.

When the process 67 is completed, the process 68 selects which shape to use for each part of the carton. Examples of the screen at that time are shown in FIGS. 13 d and e. FIG. 13 d
Is a screen for selecting a lid, the menu of the lid is displayed in the work area, and the direct sack pattern selected in the process 66 is displayed in the message area on the upper right. When the selection of the lid is completed, the screen changes to FIG. 13E, and the flow proceeds to the selection of the flap. In this screen, the shape of the lid selected in the immediately preceding process is displayed in the message area together with the direct sack pattern. Therefore, the operator can see at a glance at what stage in the series of processes the current process is going to be performed, and what has been selected in the processes so far. I have.

When all parts have been selected in process 68,
The necessary component extraction means 53 calls the pattern of the selected component from the storage device 63, and the necessary information extraction means 54 calls the predetermined connection position information of the component from the storage device 63, and the component connection of the information input means 55. The information is stored in the information setting means 56, and the dimension determined by the basis weight among the required dimensional values from the selected basis weight and the part pattern and the dimension unique to the part pattern are called from the storage device 63 and fixed information setting means 57 To be stored.

When this process is completed, the screen changes to those shown in FIGS.
It will be entered into 58 (process 69). FIG. 13f shows the main body, and FIG. 13g shows the dimensions of the flap to be input.
The dimensions to be input, that is, the number of parameters, are set to the minimum necessary in the same manner as the above-described design means using the basic pattern. Similarly, when a parameter is input, an echo is returned from a corresponding position in the parameter list display. When all the parameters of the designated parts of each component are input in this process, the arithmetic unit 60 determines the paper container shape based on the input parameters and the data of component connection information, fixed information, and combination information. In the process 70, a figure is generated to generate a paper container shape. The method of generating illustrations is basically the same as described in the design method using the basic pattern. However, in the case of this design method, it is necessary to generate the data while referring to the relationship between the connection positions of each part. Needless to say. The pattern generated in process 70 is displayed as shown in FIG. 13h. Obviously, the dimensions of the pattern correspond to the input dimensions.

When the generation of the graphic is completed in the process 70, the generated graphic is registered in the table of the storage device 63 (process 71).
The design by this means is completed.

Although the above description has been made by taking the straight sack as an example, it will be apparent that other paper container shapes can be similarly designed as long as the components and the combination positions between the components are set in advance.

(III-3) Design by Component Connection In the above-described design by combination of components, the positions where the components are connected are predetermined, but in the design by component connection described here, it is possible to select the connection positions of the components as necessary. It has been made possible. Since the shapes of the paper containers are various, there is a case where the above two design methods cannot be used in time, and a design means for designating a connection position of parts is required.

Therefore, this design means is the same as the design by component combination in that the lid, flap, etc. are prepared as components, but differs in that the operator needs to instruct which component is connected to where. ing.

The type and number of parts can be arbitrarily selected. In addition,
The difference between the above parts and the parts used in the design by part combination is that the parts to be combined are determined for each paper container shape in the part combination design, but in this design, the parts are independent of each other. Because it is.

Hereinafter, the design of a paper container by this means will be described with reference to a functional block diagram of FIG. 14, a flowchart of FIG. 15, a diagram showing an example of a display screen of FIG. It will be described with reference to FIG.

When a design by component connection is selected in the process 20 of FIG. 2, the process is started, and first, a pattern of each component is selected from a menu (process 86). Change the menu screen to the 17th
As shown in FIG. On the right side of the work area, the shapes of already designed parts, in the example shown in the figure, are displayed, and on the left side, the names of the parts to be selected next are arranged. In the lower right message area, there is displayed a "component pattern" indicating that the design of the shape is performed by component connection. When a component pattern is selected by the input device 82, the paper container component pattern selecting means 73 of the information extracting means 72 calls the selected component pattern from the storage device 84. Next, in the process 87, a figure to be used is selected from a menu from the corresponding part patterns. The screen is shown in FIG. 16b.
This is an example of a lid. When a figure is selected, the part shape selecting means 74 calls the figure from the storage device 84. Also,
The necessary information extraction means 75 calls the parameters of the selected part shape from the storage device 84, the parameters specific to the part shape are to the fixed information setting means 77, the parameters to be input by the operator are to the necessary information input means 78, The connection information is stored in the connection information input means 79, respectively. When the graphic of the part is selected, the selected graphic is displayed on the display screen together with the parameter position guide in the upper right message area, and a list of input parameters is displayed below the selected graphic, as shown in FIG. 16c. Require input of parameters, ie, dimensions. It should be noted that the graphic displayed in the work area on this screen is a graphic that has already been designed. When the operator inputs parameters according to the input guidance, this data is taken into the necessary information input means 78 of the information input means 76 (process
88). Next, the user inputs the position and the direction in which the part is to be connected to the designed figure. This design means does not have the connection position and the connection direction as internal data, unlike the above-described design method based on the combination of parts, so that such information must be input.

First, the input of the connection position will be described. Examples of the screen at this time are shown in FIGS. 16 d, e, and f. These figures are examples in which the lid is connected to the main body. A mark "." Is attached to a position where parts of the designed figure in the work area, in this case, the main body, can be connected. One of the parts to be connected to the body of the component, in this case, the lid, displayed in the upper right message area is also marked with a “•” mark. The part marked with “•” is the component connection start point displayed in the lower message area. According to this instruction, the operator inputs where to connect the component connection start point.

The input of the connection direction is performed as follows. The pattern displayed in the message area below the component at the upper right of the screen is a pattern for indicating the connection direction, the upper right connects the component upward, the lower right connects the right, the upper left connects the left, and the lower left connects the lower. Means that. Although the designated connection direction is indicated by a thick line for convenience in the drawing, it is preferable to actually change the display color. Now, when the lid is to be connected to the third panel of the main body downward, it is only necessary to indicate the component connection start point to the third panel of the main body and further indicate the lower left of the connection direction instruction pattern. Figures 16e and f show the results.
Note that the display of “part connection EXIT” in FIGS. 16 d and f is for ending the connection work of parts and creating another part or moving to the next process. A message as shown in the upper part of FIG. 16E is displayed, whereby the connection work of one component can be completed.

The above is the processing in the process 89, and the input connection position and connection direction are stored in the connection information input means 79.

When the input of the dimension value, the connection position, and the connection direction is completed for all the components, the arithmetic unit 81 generates a completed graphic based on the output of the information input means 76 (process 90).
FIG. 17 shows an example of generating a flap figure. In FIG. 17a, A,
B, C, D and ER are dimensions entered by the operator,
And are component connection start points. As shown in FIG. 17a, the coordinates of the point on the screen are (x ₁ , y ₁ ), (x ₂ ,
y ₂ ), the actual coordinate values (X ₁ , Y ₁ ) and (X ₂ , Y ₂ ) of each point on the drawing are given by the following formula, where f (x, y) is the coordinate conversion formula. Is required.

(X ₁ , Y ₁ ) = f (x ₁ , y ₁ ) (X ₂ , Y ₂ ) = f (x ₂ , y ₂ ) The distance L ₁ between the two points is obtained by the following equation. .

L ₁ = {(X ₁ -X ₂ ) ² + (Y ₁ -Y ₂ ) ² } ^1/2 Therefore, it is clear from the size relationship that an error occurs when L ₁ <(C + D).

FIG. 17b is a diagram showing the transformation of coordinates associated with the rotation of a figure around a point. The left side of the figure shows the figure that has not been rotated and the coordinate values of each point of the figure, and the right side shows the figure that has been rotated by radians and the coordinate values of each point of the figure.
The lower part shows an expression for obtaining the rotation angle. The rotation angle has a positive value in the counterclockwise direction.

As described above, since the coordinates of each point of the figure can be calculated from the input dimension value and the designated positions of the two points, the figure can be generated based on this.

When the generation of the graphic is completed, the data of the graphic is registered in the common table in a process 91, and the design is completed.

In this design means, the basis weight is not used because the parameter of the basis weight is not used, but the number of parameters to be input by the operator is set to a necessary minimum as in the above-described design means. .

As is apparent from the above description, according to this design means, it is possible to relatively easily design a paper container shape which cannot be achieved by the design means (III-1) or (III-2).

(III-4) Design by drawing The prepared component shape cannot be used, so if the connection cannot be made by the above-described component connection design,
You need to draw straight lines, circles, etc. one by one using the CAD drawing function. For this purpose, the design by drawing is provided. As mentioned earlier, since the shape of the fine part of the paper container varies depending on the use of the paper container, it is not advisable to register all shapes, and it is impossible as a practical matter, so it has been described so far. If you can't just use three design methods, you should design by drawing.

In this paper container design system, the basic commands for drawing are broadly as shown in Fig. 18,
It has three editing functions, dimension editing and annotation editing. The figure editing is for defining a figure in a drawing, the dimension editing is for adding a dimension line to a created drawing, and the comment editing is for adding a comment to the created drawing. For figure editing,
Auxiliary points that generate points in advance to define figures, auxiliary lines that generate lines in advance to define figures, auxiliary circles that generate circles in advance to define figures, line segments, polygonal lines, arcs, It has five functions of a shape definition for defining a figure using a circle and an ellipse, and a figure operation for moving, copying, rotating, flipping, and deleting a figure.

In the design based on the drawing, the input guidance is considered so that the operator can easily operate. FIG. 19 shows a message display of an input guide at the time of creating a circle. When the design by drawing is selected, the message in FIG. 19A is displayed in the message area. Now, when the operator selects an auxiliary circle, a command registered as an auxiliary circle is displayed in a menu in the message area as shown in FIG. 19B. Here, when the upper left command (the command of the auxiliary circle in FIG. 18) is selected, the display of FIG.
Input request of P _o is made. When the operator designates the center point, _Po is displayed in the lower part as shown in FIG. 19d, and an echo of input confirmation is returned. Next, input of the radius R is required. When you enter the radius value, the value is displayed and an echo is returned. When this operation is completed, a predetermined circle is drawn. According to such a message display, it is clear at a glance what kind of work is being performed, how many parameters need to be input, and how much has been input. You can do it.

(III-4-1) Determination of Graphic Now, in drawing, there is a problem that a graphic is not always uniquely determined just by inputting required parameters. For example, if it is attempted to draw a circle having a radius R that is tangent to two straight lines, there are four circles satisfying such conditions as shown in FIG. 20, so that the circle is not uniquely determined, and the operator indicates a desired circle. It is necessary. The paper container design system has been devised so that the operation of determining the figure can be easily performed.

FIG. 21 is a block diagram of figure determination, FIG. 22 is a diagram showing a flowchart thereof, and FIG. 23 is a diagram showing a display screen at that time.

Now, consider a case where the operator attempts to draw a circle that touches two straight lines. At this time, the operator uses the tablet input means 101 to select an auxiliary circle from the menu in FIG.
The fourth figure from the top right is selected from the menu (process 107). By this menu selection, the drawing function selection means 102 calls the candidate figure from the storage device 19 (FIG. 3) and displays it on the candidate figure display means 103 in the message area, and the drawing function means 104 starts drawing. The screen at that time is as shown in FIG. A straight line that has already been drawn is drawn in the work area, and the selected menu is displayed in the message area on the upper right. This also indicates that the circle tangent to the two straight lines has four candidates, which are the candidate shapes (process 10
8). An input request is displayed in a message area below the work area. From this display, in this case, it is necessary to input four conditions, that is, two straight lines L ₁ and L ₂ that are in contact with the circle, the radius R of the circle, and Pos which of the four candidates is to be adopted. You can see that. 23 and FIG single designation request of lines L ₁ at a is issued, confirmation input is returned echoes Specifying a straight line as shown in the drawing "-" mark is executed. Incidentally, L ₁ in this figure have been conveniently represented by a thick line, in fact, desirable to change the display color.
The same applies to bold lines. When the straight line L ₁ is designated, then as shown in FIG. 23 b, another indication of the straight line L ₂ is required. Specifying the straight line L ₂ is over then typing a radius R (FIG. 23 c). When the radius R is input, the screen shows four candidates as shown in FIG. 23d, and the operator selects a desired figure from these candidates. In this figure, the circle on the left side is selected as can be seen from the “•” mark. When all the conditions are input in the process 109 in this way, the optimum graphic search means 105 searches for a determined graphic (process 110), and the determined graphic display means 106, which is a work area, displays the determined graphic.
23 The decision graphic is displayed as shown in FIG.
1).

As is clear from the above description, the paper container design system can easily determine a figure in the drawing function.

(III-4-2) Interrupt processing Another problem may occur when drawing a figure using the drawing function. For example, if you are trying to perform some processing and the part is too small to be easily understood, you need to enlarge that part and perform the processing. In some cases. In such a case, it is very convenient if necessary processing such as enlargement or deletion can be performed by interruption. Therefore, in the paper container design system, while performing a certain process using the drawing function, another process is called to perform an interrupt process, and when the process is completed, the process returns to the original process and the work can be continued. I have to.

Hereinafter, the interrupt process will be described with reference to the block diagram of the interrupt process in FIG. 24, the flowchart in FIG. 25, and the diagram showing the tablet menu in FIG.

When the drawing function is selected by the tablet input means 120, the drawing function selecting means 121 calls up a menu related to the drawing function from a storage device not shown and displays the selected function displaying means 123.
To be displayed. The selection function display means 123 corresponds to a message area on the screen. The drawing function means 122 executes the selected drawing function, and the result is displayed on the result display means 124. As a result, the display means 124 corresponds to a work area on the screen. The above processing is the process 127, 128, 129, 131,
This is a flow of 132, which is a normal drawing process.

In the process 128, when an interrupt process is selected by the tablet input unit 120 while a certain process is being executed, the interrupt process selecting unit 125 detects that and selects the interrupt process.
Activate 26. This is the interrupt processing in the process 130, and when it is completed, the original processing is continued in the process 131. The interrupt processing is started by instructing the menu shown in FIG. This menu can of course be displayed on the screen if there is room, but such a screen display menu can be selected only after it is displayed. Is not appropriate as a menu of a process to be executed at any time according to the above, and it is preferable that the menu is fixedly displayed on the tablet so that the process can always be executed.

A specific example of the enlargement interrupt processing will be described with reference to FIGS. 27 and 28. On the screen shown in FIG. 28A, if the user selects dimension editing in the process 133 in order to insert a dimension in the created figure, the screen becomes as shown in FIG. 28B, and a request for selecting the type of the dimension line is made. Note that the symbol type in the figure is a menu for setting the shape of the end of the dimension line, and the operation mode change is a menu used when directly changing the current operation to another operation. If the vertical dimension line is selected in the process 134, and it is desired to enlarge the end portion of the dimension line to make it easier to specify, select "enlarge" from the tablet menu and specify the area to be enlarged (process 135). As a result, FIG.
The operator specifies the position of the dimension leader on the enlarged figure (process 136). In FIG. 28c, the designated position is indicated by a “•” mark. Next, the other position must be specified, but cannot be performed as it is. In process 137, "magnification OFF" is instructed from the tablet menu to temporarily end the enlargement processing and return the screen to the original state (process 138). , FIG. 28d), again selecting the enlargement process from the tablet menu (process 139). When the designated area is enlarged and displayed as shown in FIG. 28e, the other position of the leader line is designated (process 140). The designated position is indicated by a “•” mark in FIG. 28e. When the position specification is completed, enlargement is turned off and the figure is returned to its original state (process 1
41). FIG. 28f shows the screen at that time. The operator specifies the height at which the dimension value is to be displayed on this screen (indicated by “•” in the figure), and then inputs transmission of the screen menu (process 142). Then, the dimension line distance is calculated in the process 143, and the dimension line is displayed as shown in FIG. 28g.

This completes a series of enlargement processing. As is clear from the above description, this paper container design system is very convenient because interrupt processing can be easily performed whenever necessary simply by selecting a tablet menu. It has become something.

As mentioned above, the design based on the drawing has been described. However, since the basic commands are extensive, the drawing processing can be easily performed, and the determination of the figure and the interrupt processing can be easily performed, so that the operator is familiar with the paper container design system. Without this, it is possible to efficiently create figures.

(III-5) Mutual movement between design means Although the above four design means have been described above, one design means is selected first, and a series of paper containers are designed by the design means. It has been described as something to be done. That is, as shown in FIG. 29a, the menu of the four design means has been given by a tablet menu or key input, etc., but as shown in FIG. 29b, the basic pattern and the combination of parts are combined into one menu. You can also. This has the following meaning. FIGS. 8 and 13a
In the example of FIG. 8b, when the screen on the left and the screen b are the same, when the shape on the left side is selected, the design routine based on the basic pattern is entered, and when the shape on the right side is selected, the design routine based on the combination of parts is entered. It should be programmed as follows. That is, when the "basic pattern / component combination" menu in FIG. 29b is selected, the screen is initially the same, but the screen is divided into screens by respective design means depending on the selected shape.

The same applies when there are many more shapes.Some of the shapes are registered as basic patterns, and when one of the shapes is selected, the design is based on the basic pattern. It will be clear that it is only necessary to make it possible to perform a combination design.

In addition, menus for component connection and drawing can be selected as appropriate. For example, in FIG. 13, if it is desired to perform the combination of parts up to the selection of the lid shown in FIG. D, and to perform the flap by connecting the parts, at that time, select the “parts connection” menu in FIG. 29a or b. Then, a desired shape may be selected by calling the menu of the flap, and a special space in the completed figure shown in FIG. 8e (a hole may be made in a part of the panel so that the contents can be seen from the outside). If you want to use the drawing function to make
Alternatively, drawing can be performed by selecting the "drawing" menu of b. It goes without saying that it is also possible to return to component connection after drawing the shape of a certain part.

The movement between the design means described above corresponds to a loop returning from the process 22 or 23 to the process 20 in FIG.

In this way, the paper container design system can be arbitrarily moved between the four design means, so that the paper container can be designed by an optimal design method according to the situation.

(III-6) Automatic Scale When a figure is created on a graphic display, the figure being created needs to be displayed on the screen without bias and without protruding. This is because the operator cannot easily determine whether a desired graphic has been created unless the entire graphic is always contained in the screen. Such a situation is the same in the design method described so far. As shown in FIG. 30A, when the shape of a created figure or a figure called from a database is changed by connecting parts or drawing, FIG. May protrude from the work area. Also, in the design using the basic pattern, when displaying a completed graphic, the graphic must be displayed without bias and without protruding.
In such a case, the automatic scale is used to re-display the figure with an appropriate size as shown in FIG. 30c.

Hereinafter, the automatic scaling will be described with reference to the block diagram of FIG. 31 and the flowchart of FIG. First, the data extracting unit 151 extracts all the pixels registered in the graphic table for the graphic data being designed from the storage device 150 (process 156), and circumscribes the rectangle extracted by the circumscribed rectangle calculation unit 152. Is calculated (process 157). FIG. 33 shows how to select a circumscribed rectangle for an arc. In the figure, (x ₀ , y ₀ ) indicates the center of the arc, and R indicates the radius of the arc. In process 158, a circumscribed rectangle is calculated for all pixels, and the maximum coordinates ((x _max , y _max ) in FIG. 33) and the minimum coordinates ((x _min , y in FIG. 33)
_When the calculation of _min )) is completed, the screen setting calculation unit 153 sets the scale of the process 159. Scale setting is to determine the length of the side of the circumscribed rectangle from the maximum and minimum coordinates of the circumscribed rectangle obtained in process 157, compare the length of this side with the length of the side of the viewport of the work area, and further,
By making the center of the circumscribed rectangle coincide with the center of the work area, the figure can be displayed in the work area window in an optimal state without protruding. The figure scaled in process 159 is displayed on display means 1.
The size is appropriate for the work area of CRT155 via 54, and
It is displayed again without protruding (process 160). 30th
FIG. C shows an example of the redisplay screen. It goes without saying that the redisplay is performed after the previously displayed graphic, that is, the graphic protruding from the work area is temporarily deleted.

This automatic scale processing need not always be performed, but may be performed every time the drawing processing of one minimum unit, such as the connection of one part or the drawing of one figure, is completed.
Therefore, the automatic scaling process may be started when the “component connection EXIT”, the “basic command EXIT”, and the design means menu in FIG. 29 are selected.

As described above, the paper container design system automatically calculates the display magnification of the figure and always displays the whole figure in the work area, so that the operator can always grasp the whole figure accurately.

(IV) Allocation When a desired paper container shape is completed by the shape design, the shape must be allocated next to create a punching die.

In this paper container design system, two types of allocation are prepared as allocation means: interactive allocation and automatic allocation. The reason is,
In most cases, automatic assignment is sufficient, but it is better for the operator to assign specially shaped boxes.

(IV-1) Interactive allocation This interactive allocation is one in which the operator performs the most efficient allocation in consideration of the paper container shape, its dimensions, the paper to be used, or the manufacturing process, and the block diagram is shown in FIG. ,
FIG. 35 shows a flowchart, and FIG. 36 shows a display screen thereof.

The interactive assignment is started by selecting the tablet menu or the screen display menu. FIG. 36a shows the screen. Here, the operator inputs the registration code of the box shape to call the box shape to be assigned (process
177). When the registration code is input from the input device 170, the one-sided shape calling unit 172 calls the box shape with the registration code from the storage device 175, sends the data to the multi-sided placement unit 173, and displays the data on a display device (not shown). I do.
The screen is shown in FIG. 36b. Next, the operator selects the process type according to the input request on this screen, and further inputs the paper size. The process type refers to whether to perform branch and leaf printing as shown in the message area at the top of FIG.
Whether to perform roll-up printing and roll-up punching, or roll-up printing to perform branch-leaf punching. When these inputs are completed, the screen changes as shown in FIG. 36C, and an echo of the input confirmation is returned, so that the operator can confirm the input data. This processing is the input of the allocation information of the process 178. When the processing so far is completed, FIG. 36 d
Screen is displayed, and an input of an arrangement pattern is requested. At this time, a designated size of the branch paper is displayed in the work area of the screen. The arrangement pattern is a pattern for arranging the paper container shape on the layout drawing. As shown in FIG. 37, nine empirically known basic arrangement patterns are stored in the storage device 175 in advance. It is registered. In the figure, the mark “▲” is the center of the circumscribed rectangle of the paper container shape, x and y are the pitches between the center points in the horizontal direction and the vertical direction, and x _i and y _i are the steps in the horizontal and vertical directions, that is, This is the amount of deviation between the center points. In FIG. 37, one set of four shapes is used. However, since the number of one unit varies depending on the shape of the paper container and the width of the paper used, more arrangement patterns may be registered.

When the operator inputs an arrangement pattern on the screen shown in FIG. 36D (process 179), the arrangement pattern selection means 171 calls the arrangement pattern selected from the storage device 175 and sends the data to the multi-plane arrangement means 173. Once the layout pattern is entered, the screen will look like Figure 36e, and the operator will enter the number of layouts, pitches, and step dimensions for each of the horizontal and vertical directions (process 180). These data are supplied from the input device 170 to the multi-plane arrangement unit 173 via the arrangement pattern selection unit 171 and the arrangement pattern is calculated. As a result, the box shape is automatically arranged at the center point of the arrangement pattern as shown in FIG. 36f, and is displayed on the screen together with dimension lines such as pitches (process 181). It will be apparent that automatic scaling is performed on the screen display described above.

Any missing dimension lines in this placement pattern are entered using the dimensional edits of the drafting design, and any necessary annotations are made to complete the drawing (process 182). Of course, it is possible to use the annotation editing of the drawing design for the entry of the annotation, but the frequently used annotation may be registered in a storage device in advance, and the necessary annotation may be called up. . Although this may be the only layout drawing, it is also preferable to record information such as the customer, product name, paper size, paper grain, and processing machine. Process 183 is a process for that. When this process ends and the layout drawing is completed, the drawing is registered (process 184). Registration of a drawing is performed by designating “registration” in a screen display menu and inputting a registration code. This processing is performed under the control of the allocation registration means 174, and the registration code is stored in the storage device 17 together with the allocation drawing.
Stored in 5. When the registration is completed, the allocation registering unit 174 issues a command for immediate output to the output device 176 (process 185).
As a result, the output device 176 calls out the drawing data from the storage device 175 and outputs the layout drawing and the original layout drawing. For example, as shown in FIG. 38, the layout drawing is a drawing in which a box shape, dimension lines, annotations, drawing column information, etc. are arranged for a specified number of sheets. The drawing drawn in is used for confirming the cutting die at the manufacturing site. In this case, a raster plotter, an XY plotter, or the like is used as an output device.

In the above description, one box shape is assigned.
It is also possible to assign multiple box shapes by specifying multiple box shapes in 7.

(IV-2) Automatic layout In the interactive layout, the layout of the boxes is selected by the operator. However, in the automatic layout described here, all layout patterns that can be taken by one or a plurality of boxes are defined on standard paper, special paper, and the like. The most economical allocation is performed by calculating for all the sheets and simulating each of the calculated allocations.

Hereinafter, the automatic assignment will be described with reference to the block diagram of FIG. 39 and the flowchart of FIG.

The pre-allocation process in the process 199 is a process for preparing data necessary for the automatic allocation.
Enter the number of copies, paper, paper weight and printing style.
When these data are input from the input device 190, the standard paper calculation means 191 performs standard paper allocation of the process 200,
The special paper calculating means 192 performs special paper allocation in the process 201. The standard paper layout means that, for all paper sizes determined by the designated paper, the layout pattern determined by the box shape and the layout pitch calculation formula are used to determine the layout number. The special paper layout means that when boxes are arranged by the number of layouts calculated for the standard paper, the smallest paper size that can accommodate all of the arranged boxes is obtained.

The formula for calculating the layout pattern and layout pitch in the standard paper calculation means 191 is determined for each box shape and is stored in advance in the storage device.
It is stored in 197, but in the case of a straight sack, it is as shown in FIG. It should be noted that the character expression of the term of the allocation pitch calculation formula in the figure is defined as shown in FIG. 42, and the dove is a value determined by the box shape. The formula for calculating the special paper size in the special paper operation means 192 is as follows.
It is as shown in the figure.

When these assignments are completed, the assignment simulation means 193 simulates the assignment. This layout simulation calculates the printing conditions from the paper size and the number of layouts calculated as a result of the processes 199 and 200 and the data input in the preprocessing of the process 199, and obtains the most efficient layout. In FIG. 44, a calculation as shown in FIG. 44 is performed, and the optimum assignment is selected under the following conditions.

Condition 1) When the paper size is full format (number of prints) ≥ A1 When the paper size is half-size A2 sheets ≥ (number of prints) ≥ A3 When the paper size is 3 or 4 (the number of prints) ≤ A4 sheets A1 to A4 Each is a unique value.

However, those that do not satisfy the above conditions are excluded from the optimum paper.

Condition 2) When the type of paper is court ball type (paper weight) ≧ A5 When the type of paper is special paperboard (paper weight) ≧ A6 If the above condition is satisfied, select the optimum paper from special paper. In the above equation, A5 and A6 are unique values.

Condition 3) Among the sheets selected from the conditions 1 and 2, the sheet having the smallest area per box is determined as the optimum sheet.

However, if there is no sheet satisfying the above conditions, it is determined that there is no optimum sheet.

When the allocation simulation is completed in the process 202, the output device 198 performs the output process of the process 203. In this output process, two outputs, ie, an output item list and an allocation drawing, are used for use in the manufacturing process, business estimation, and the like. The output item list is a list of paper sizes, the number of layouts, and printing conditions obtained by simulation. FIG. 45 shows an example of the output item list when special paperboard paper is used. In the figure, a mark “*” means that some number is described, and a mark “/” means that the value is the same as that in the column above. In addition, the layout drawing outputs each item of the output item list as needed. It should be noted that the multi-plane arrangement means 19 in FIG.
5. The functions of the assignment information registration means 196 and the storage device 197 are the same as those described in the interactive assignment.

Since the assignment is automatically performed as described above, the burden on the operator is reduced and the work is performed efficiently.

(V) Input Guidance Input guidance for messages and the like displayed on the display screen has been described above, but will be organized and described here. Note that the circuit configuration for displaying characters and figures and the circuit configuration for displaying a window that divides the display screen into regions are well known, and a description thereof will be omitted.

A block diagram for input guidance is shown in FIG. 46, and its flowchart is shown in FIG.

The screen of FIG. 13g is reproduced in FIG. 48, and the input guidance of the paper container designing system will be described using this screen as an example. This screen is a screen when the dimension value of the lid is being input in the design based on the component combination. When the lid dimension input is started, the paper container shape input guidance pattern generation unit 211 calls up the lid pattern from a storage device (not shown), and inputs the lid pattern via the input guidance enhancement unit 213, the input data analysis unit 214, and the message pattern output unit 216. To display on the screen (process 22
0). That is the lid pattern displayed in the work area in FIG. Next, the input guide message generator 212 calls a message for the case of inputting the size of the lid from the storage device and similarly displays it on the screen (process 221). It is displayed in the message area in FIG. In the upper right area, the direct sack pattern selected in the previous process is displayed, and in a lower area, a list of parameters is displayed. In the lower area, a message requesting input of a dimension value is displayed. Although not discriminated in the drawings, each display is displayed in a different color. Which part is made in what color is arbitrary, for example, as follows.

Green: All cuts White: Pressed lines, sewing blades, half-cutting blades Yellow: Input parameters in the work area, and their dimension lines, input request messages, input parameters in the parameter list Red: Parameters currently required to be input, and their Dimension line Blue: Parameters determined by basis weight Orange: Echo The ground color is black.

Therefore, in FIG. 48, the pattern of the work area is such that all cuts are displayed in green, the pressing rule between pawls is displayed in white, and if a parameter B is requested to be input, B and its dimension line are red. Other parameters and their dimension lines are displayed in yellow. The same is true of the direct sack pattern in the upper right message area. All cuts are green, and other lines are white. In this case, since the lid is being processed, the lid is displayed in red. In the parameter list, five parameters to be input by the operator, A, B, C, X, and R1, are displayed in yellow, but H1 and H2 determined by the basis weight are displayed in blue. As described above, this is not a parameter to be input by the operator, but is displayed to inform the operator that there are two values determined by the basis weight. In the figure, A and X have already been input, and the input dimension values are displayed in orange. This is the echo. This allows the operator to confirm the input. The input request message at the bottom is displayed in yellow.

By the way, when the process 221 ends, the input guidance emphasizing unit 213 emphasizes the input location (process 222). This is performed by changing the yellow display to the red display as described above. When an input is made in the process 223, the input data analysis unit 214 performs an error check on the input dimension value using an error check formula (13 item in FIG. 5) stored in the storage device. For example, an error message is displayed to display an error, and if there is no error, an echo generation command is given to the input echo generation unit 215. The echo is performed by displaying the input value in the parameter list in orange as described above. This is the process of the process 224. When the processes 222, 223, and 224 are completed for all the parameters, drawing is performed in accordance with the dimension values in the process 226, and a series of input guidance ends.

As can be seen from FIG. 48 or other display screen diagrams,
The displayed parameters are only the parameters to be input by the operator except for the value determined by the basis weight. As mentioned before, some parameters are determined by the shape and some are calculated from the input parameters. However, displaying all these parameters only makes it hard to see, In fact, the operator does not need to know these parameters. However, when the operator wants to know, it is better to be able to display it. As a configuration for that, by selecting the display of all parameters from the tablet menu etc.,
What is necessary is just to call up those values from the storage device and display them on the screen.

The above is an example of the design by the combination of parts, but the same applies to the design by the basic pattern and the design by the connection of the parts. Input guidance for basic commands
As described with reference to FIG. 19, all parameters to be input are displayed, and an echo is returned each time a parameter is input, so that the next parameter to be input can be clearly recognized, and the parameter currently input is It is made possible to check what position it is in.

It should be noted that what kind of area the screen is divided into, how to display colors, and what to do with the words of the message can be appropriately selected and are limited to the above-described embodiment. is not.

As described above, in the present paper container design system, the input guide message and the combination of the input guide patterns are displayed on the screen, so that the input location can be clearly indicated to the operator, and therefore, input errors can be reduced.

[Effects of the Invention] As is clear from the above description, according to the present invention, by selecting the enlargement interrupt key of the input means, a desired area of the graphic can be enlarged and displayed by the interruption processing, so that the operability is excellent. Is what it is. When the enlargement interruption processing is completed, the processing returns to the original processing, so that the processing can be continuously performed without being affected by the enlargement interruption processing.
