Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package design system capable of automatically designing the structure of a package such as a paper container or a cardboard box using a computer.

[0002]

2. Description of the Related Art Conventionally, the work for designing the structure of a package such as a paper container or a cardboard box is basically the contents, basic dimensions, paper quality, paper thickness, filling for filling the package with the contents. An expert (designer) who has abundant design experience, taking into consideration various conditions as a package such as the type of machine and customer's taste, etc., based on his own experience Is to draw.

In recent years, CAD using a computer
The method of introducing the system, inputting the two-dimensional coordinates of the package with a tablet, a mouse, etc., and digitizing the development view to design the structure of the package is used. Further, in the above method, basic pattern data having shape data of each part of the package (package body part, package parts, etc.) and additional data such as parameters of dimensional numerical values of each part are input to the CAD system in advance. The method of deciding the package structure by selecting and exchanging the data of each part from the input data and then finally determining the parameters of the dimensional numerical value of each part based on the experience of the expert himself is is there.

Then, a blank sample is assembled based on the development view created by the CAD system as described above.
Then, it is confirmed that there is no distortion or deviation in the form of this sample package, and whether or not the form of the package meets the above conditions.

[0005]

By the way, unless a specialist who has a good understanding of the structure of a package and its designing method has a great deal of design experience, it is possible to actually assemble a package and design a package suitable for the purpose. Was difficult. In other words, when an inexperienced designer designs a package, it is difficult to assume a development view based on the package shape, or conversely, a completed package from the development view of the package. It is not possible to accurately consider the size of each part of the corresponding package such as paper and paper quality and the fit between the parts, and moreover, the knowledge of the shape of the package itself or the shape corresponding to the purpose and function of each component of the package is insufficient. Therefore, when creating a blank sample based on the designed development view, it is highly likely that the components will not fit well and the blank sample will not be assembled well, or the assembled blank sample will be distorted, It was often a redesign.

Therefore, the actual shape cannot be confirmed without assembling the blank sample, and at the stage of assembling the blank sample, the form of the package is unusable or the design is not satisfactory. If it wasn't needed, it was necessary to repeat the process from the revision of the development drawing.

Further, even when an expert prepares a development drawing, the CAD system inputs such as determining the concept of the package form, manually inputting two-dimensional coordinate values and inputting dimension parameter values. The work, the creation and correction of the development drawing by the manual operation on the display screen of the CAD system, the work of creating a blank sample, etc. are repeated, and the structural design is carried out through trial and error for the optimum design, so much labor and effort are required. Was spending time.

Further, in the system in which the basic pattern data is inputted in advance as described above, the data of each part constituting the structure of the package merely defines the planar shape thereof, and the development view is converted into a three-dimensional package. If the inexperienced designer or the like designs using this system, there is a high possibility that the same result as described above will be obtained without taking into consideration the fit between the respective parts when doing.

In particular, on the CAD system, the operator selects an operation of exchanging a part of the development view forming the package for an arbitrary part, or selects an operation of adding a part to the development view to select the package. When the form changes, the replaced or added part does not always match the other part in the development view, and it is not guaranteed that the form as a package is maintained. Therefore, when the blank sample is assembled based on the development view after the parts are changed, there is a possibility that the sample is not assembled properly or the package is distorted. That is, CA
Even in the development drawing designed by the D system, it was unclear whether or not it would be a package until a blank sample was assembled.

The present invention has been made to solve the above-mentioned problems, and can significantly reduce the labor and time involved in the structural design of packages such as paper containers and corrugated boxes, and also provide design experience. The purpose of the present invention is to provide a package design system that enables a package configuration design to be performed easily even by an expert who is not abundant and that the designed package has reliability as a package without distortion. There is.

The management information includes the name of the customer who ordered the package, the product name of the package, the development drawing number of the package, and the like. The other information is, for example, an instruction given by a designer (operator) such as selection of a component during processing by the calculation means 4 described later.

The storage means 2 includes package use purpose information indicating the purpose of use of the package, package structure information for determining the form of the package, package component information indicating components of a basic pattern that is the basic form of the package,
Joining rule information indicating the joining rule between the above-mentioned constituent parts, inference rule information for inferring the structural shape of the package, part graphic shape information indicating the shape of the constituent parts, part use purpose information indicating the purpose of use of the constituent parts, and configuration It stores, as a database, part group information in which parts are classified and grouped, and display and output information for determining display data and output data required in the next process such as dimensions of constituent parts.

The above-mentioned basic pattern is, as shown in FIGS. 3A and 3B, a developed view formed by combining the minimum necessary components when assembling the package, The database stores a large number of basic patterns classified by the contents of the package, the purpose of use of the package, the basic dimensions of the package, and the like.

The package use purpose information is used to select a basic pattern classified by basic information such as the type of contents, and a basic pattern corresponding to each basic information such as contents is determined. For example, as shown in FIG. 4, basic patterns of a plurality of packages are categorized and stored for each content to be stored in a package such as soap, confectionery, medicine, medical supplies (in FIG. 4,
A, B, C, etc. refer to types of basic patterns).

The package structure information is a function of the package (for example, when the package sells the content as a product, a function of showing the content to the consumer from the outside of the package, a function of carrying the package, and ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, (((function (s)) (((((((((,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,.,) Areas), the functions that lock them when the package is inserted, etc.)))))

That is, regarding the package structure information, which of the basic patterns is optimal for achieving this function with respect to the function of the package, and how the components of the basic pattern must be combined. This is used as information, and is for automatically changing the component such as the replacement and addition of the component in the basic pattern so as to be adapted to the selection of the basic pattern and the function of the package.

The package component information indicates what component the basic pattern showing the developed view of the package is made up of. For example, a code No. indicating each component. Etc. are defined,
The basic pattern is made up of the code No. It is shown by using. In addition, each component may not be one component in one package component information, but may be component group information described later. Select one component from the component group of this component group information. You can do it. Further, the package component information has a component or a component group that can be added to the basic pattern as information.

Further, in the package component information, the package component information may limit usable components or component groups and components in the component groups. In addition, in the package component information, the addable component or component group may be indispensable depending on the package structure information.

The connection rule information is a rule regarding the connection of the constituent parts that must be connected according to the structural state of the basic pattern, and the rule is for each figure, part group, or part that has the structure of the basic pattern. It is the information described in. That is, the connection rule information is a rule that determines which component is to be connected to each component. For example, the rule is as shown in FIG.
In the above, the parts 11 are the parts 12, 1
3. The parts 14 are joined together.

The inference rule information is, in the system of the present embodiment, information that the package designer inputs in advance (the basic information and design information) and a package structural form output corresponding to this information. A simulation is performed using a pattern, and it is determined whether the package structure of a large number of patterns determined by this simulation holds as an actual package corresponding to the input design conditions, and based on these determinations, the component parts It is the information that defines the mutual relations of and describes the conditions for actually being a package as rules.

That is, the inference rule information is such that the ratio and the like of the component parts in the package component part information are determined so as to correspond to each other, and the basic size and the size of one part are determined. Thus, the dimensions of other components can be calculated in consideration of the paper thickness and the like. The package can be assembled accurately by using each component whose dimensions are calculated according to this inference rule.

The part graphic shape information is information defining the individual shapes of the constituent parts. The dimensions of the component parts are determined according to the rules of the inference rule information, and only the shapes of the component parts are defined in the part graphic shape information.

The part use purpose information is in accordance with basic information,
When determining the structure of the basic pattern, it is information that defines the use and function of each component. Specifically, the purpose is information on which part of the package such as the bottom, lid, and side wall of the package is used, and the function is a handle hole for holding the component when carrying the package. Or a part that locks when the lid of the package is closed.

In the component group group information, it is possible to classify the component parts according to the purpose of use such as function and purpose, group a plurality of parts having the same purpose of use into one group, and handle this group as one part. The information is described as follows. That is, in the component information of the package, a plurality of components that can be changed or added without changing the reliability of the package and the like are grouped into one component group.

The display and output information are calculated by the calculating means 4 which will be described later.
This is the information for selecting the information such as the dimensions required in the actual next process after the work by is completed.The information selected based on this display and output information is the specifications and design for the next process. It is designed to be output or displayed as a diagram. Then, the display and output information are described for each of the figures and the constituent parts that form the basic pattern.

On the other hand, the computing means 4 responds to the basic information and the design information from the input means 1 by using the package use purpose information, the package structure information, the package component information, the coupling rule information stored in the storage means 2, It has a database search function for searching inference rule information, part figure shape information, part usage purpose information, part group information, and other information.

The calculation means 4 has a function of determining the package structure desired by the designer based on the result of searching various information according to the input basic information and design information. Then, in the function of determining the structure of the package, the calculating means 4 determines whether or not the structure of the package determined by combining the respective parts based on the combination rule description information satisfies the form of the package. It has a check function to automatically perform.

Whether or not the form of these packages is a package that can actually be used in consideration of the design conditions (basic dimensions, paper quality, paper thickness, filling machine, etc.) already input by the input means and the inference rule information. It has a structural design inference function that makes a judgment as to whether or not there is an inconvenient part and performs processing so as to endure use as an actual package.

Further, it has a fine adjustment function that allows a slight change in the form of the package, a change in the dimension value, etc. to the design result while using the structure design inference function again.

By exchanging parts or adding parts while using the structural design inference function again in accordance with the operator's desire, reliability is not lost as an actual package,
It has a parts operation function that can replace parts and add parts. Then, it has a display function for displaying the design result on the display means 3 based on the display and output information for determining the display data and the output data necessary for the next process such as the dimension. The output means 5 outputs the design result obtained by the arithmetic processing means 4 and selected based on the display and output information as a development view, a blank sheet sample, or the like.

Next, the operation of the package design system configured as described above will be described with reference to the flowchart shown in FIG. First, the designer uses the input means 1
For example, basic information such as "medicine" (contents, structure of package regarding intended use, grain, size display unit, etc.), and
Enter the minimum required design condition information (basic dimensions, paper quality, paper thickness, filling machine, etc.) required for structural design (sp1, s)
p2).

Based on these input information, the database of the package use purpose information and the package structure information is searched by the calculating means, and the basic pattern corresponding to the basic information and the design information is selected (sp3).
At this time, if the basic information and the design condition information are deficient or there is no corresponding basic pattern in the database, the selection becomes impossible, and the calculation means 4 requests re-input of the basic information and the design information ( sp4, sp5).

When there are a plurality of selected basic patterns, the calculating means 4 requests the designer to select one basic pattern, so that the designer selects one basic pattern (sp6). , Sp7). Regarding the constituent parts of the selected basic pattern, which consist of parts groups, the computing means 4 searches the parts usage purpose information stored as a database based on the basic information and the design condition information input. By this, the component corresponding to the purpose of use is selected from the component group (sp8).

For example, when "a lock function is required to insert the lid" is selected as the design condition information, the component use purpose information of the component use purpose information is obtained from the component group which is the cover panel 15 (shown in FIG. 3A). A component suitable for the component having the insertion lock function is selected. Further, when it is difficult to automatically select a part with only the input information, the operator requests the information input or the operator himself / herself to select a component (sp9, sp1).
0).

Next, when the configuration of the component parts in the basic pattern is determined, the shape of the component parts is determined by the calculation means 4. Parameters such as dimensions required to determine each shape are described in the inference rule information. For example, in the part x shown in FIG. 6, the part x is “part x
Height B1 is B1 = A0 / 2 with respect to the width A0 of the part x.
It must correspond to the expression of −10, and the widths of the parts x and y must both be A0. It is defined by the inference rule.

With this inference rule information, the parameter values are determined based on the basic dimensions of the design condition information, and the dimensions and shape of the component are determined (step sp11). The parts to be combined with each part are obtained from the combination rule information. The arithmetic means 4 requests the designer to input or re-input the design information that is insufficient or inconsistent at the stage of inference.

By making the above inference, it is possible to determine the optimum shape and size of each component for the input information and to check the reliability of the package. Here, the reliability check means that the size of each component is determined according to the above inference rule information, and if there is any information that contradicts these inference rule information, it is re-entered to reconcile it. Is removed to show that the size and shape of each component are in line with the inference rule information.

When the shapes of all parts are determined, the parts are combined according to the basic pattern and the combination rule information (s
p12). That is, the individual coordinate system as a component is converted into the overall coordinate system. It should be noted that package use purpose information, package component information (basic pattern), coupling rule information, inference rule information, component figure shape information, components that are searched or arithmetically processed based on the input basic information and design condition information. The purpose-of-use information, the component group information, and the like are obtained by accumulating know-how of package design, and these pieces of information are described so that the reliability of the package can be maintained. By using this information, the reliability of the structurally designed package is maintained.

Next, based on the determined drawing shape of the package, display and output information for determining display data required in the next step such as dimensions are searched, and the data necessary for the next step is displayed on the display means 3. Is displayed (sp13).

Next, the process proceeds to the next process selection (sp14). In the next process selection, design condition change (sp15), component replacement (sp16), component addition (sp17), fine adjustment (s)
The operator selects the registration designation work (sp19) (p18).

When it is desired to change some of the design conditions (basic dimensions, paper quality, paper thickness, filling machine, etc.) already input from the input means 1 in the next processing selection, for example, the size of the contents to be stored in the package. Has been changed, so if you want to change the basic dimensions and design again, input means 1
The design condition can be changed by selecting the design condition change (sp15) through.

Then, after changing the setting conditions, the shapes and dimensions of the respective components are recalculated according to the inference rule information, and then the respective components are recombined in accordance with the coupling rule information and the drawing shape of the package is again obtained. Decide. And
After the structural form is displayed (sp13), the next process is selected (sp1).
Return to 4).

Further, in the next process selection, part replacement (s
When p16) is selected, the items of each component part group belonging to the basic pattern retrieved by the arithmetic processing means 4 are displayed on the display screen so that they can be identified, and the designer's instruction is requested. Then, the display part 3 displays the components of the replaceable component group of the item instructed by the designer.

These constituent parts are defined by the constituent part group information and the package constituent part information as being usable in the selected basic pattern. Then, in the arithmetic processing process described above, one of the constituent parts of the constituent part group is selected by the calculating means 4 in accordance with the part usage purpose information.
However, if the designer determines that the other components in the component group are more suitable for their intended use,
The component and the component selected by the calculation means 4 can be exchanged.

Then, when the designer selects the part to be replaced, the constituent parts of the basic pattern are replaced, the shapes and dimensions of the respective constituent parts are recalculated according to the inference rule information, and then combined. According to the rule information, each component is combined and the drawing shape of the package is determined again.
Then, after the structural form is displayed (sp13), the process returns to the next process selection (sp14).

In addition, in the next process selection, a part addition (s
When p17) is selected, the items of each addable component group belonging to the basic pattern retrieved by the arithmetic processing means 4 are displayed on the display screen so that they can be identified,
Seek designers' instructions. Then, the parts of the parts group to which the item whose instruction is input by the designer can be added are displayed on the display unit 3.
Displayed by.

These components are defined by the component group information and the package component information as being able to be added and used in the basic pattern without impairing the reliability of the package. The component can be added if desired. When the component to be added is selected, the shape and size of each component are recalculated according to the inference rule information, and then the component is recombined according to the coupling rule information and the drawing shape of the package is re-calculated. Decide. Then, after the structural form is displayed (sp13), the next process is selected (sp
Return to 14).

For example, when it is newly designed during the designing to make a handle hole in the package for which the information that can be carried is not entered in the basic information, the addition of parts is selected by the next process selection. On the surface image, if you specify the type of intended part to be added and the part to be connected (in this case, a handle hole), and if structural design inference is performed again, select the component on the left and right target surfaces of the package panel and combine it. In accordance with the binding rules that must be done, handle holes are also added to panels that do not indicate. Further, along with the change in structure due to replacement of parts, the shapes and dimensional numerical values of related parts are also automatically changed and displayed.

In the next process selection, when the selected item is the fine adjustment (sp18), the designer gives an instruction among the dimensions of each component calculated by the calculation means 4 and displayed on the display means. The item can be changed on the display means. Then, after changing various dimensions and the like, the shape and dimensions of each component are recalculated according to the inference rule information in a state with the changed dimensions as a reference, and then,
According to the joining rule information, each component is joined and the drawing shape of the package is determined again. Then, after the structural form is displayed (sp13), the process returns to the next process selection (sp14).

For example, when it is desired to increase the height of the flap 17 (shown in FIG. 3A) to some extent, the numerical value of the dimension of one flap 17 on the display screen is designated, the dimension value is changed, and the structure is reconstructed. When design inference is performed, when a component having the same part shape as the changed flap 17 is connected, or when the cover panel 15 / cover tack 16 (shown in FIG. 3) related to the flap 17 is connected. Is that, along with the changed numerical values, the numerical values of the related parts are automatically changed and displayed.

Then, after the change of the basic pattern such as component replacement is completed, the registration designation work is selected in the next process selection. Then, the obtained design result is registered. When finally registering, management information (customer name, product name, development drawing number, etc.) of the design result is input through the input means 1.

Next, the design result and the management information as described above are output by the output means 5. If the output means 5 is, for example, an XY plotter, a package development drawing, and if it is a cutting plotter, an output product such as a blank sample is automatically output. Similarly, it is also possible to output a copyboard necessary for creating a copyboard.

As described above, the package design system of the present embodiment includes the package use purpose information represented by the contents, the package structure information for determining the package form, and the component parts of the basic pattern which is the basic form of the package. Package component information that indicates, component connection description information, inference rule information for inferring the structural shape of the package, part graphic shape information that indicates the shape of each component,
Display and output of parts use purpose information that shows the function of each component, component part group information in which multiple components are classified according to the purpose of use, and display data required in the next process such as dimensions Information is stored in a database, so unlike the conventional manual design,
It becomes possible to design the structure of the package in an extremely short time.

Further, the designer has basic information (contents, structure of the package related to the purpose of use, grain of paper, unit of size display, etc.)
And the package is designed by giving simple information such as minimum design condition information (basic dimensions, paper quality, paper thickness, filling machine, etc.) required for structural design, so experts with extensive design experience can Of course, even a person who has little design experience can easily and accurately perform optimum structural design.

Further, after the structural design is completed, an output product such as a developed view of the package and a blank sample can be obtained. Moreover, the idea of the package structure desired by the designer is not in mind,
By displaying on a graphic display, the image is distorted to support structural design with variations. In addition, since the reliability of the package, such as the form and size of the package, which cannot be achieved without actually assembling a blank sample, is automatically judged, the reliability of the package is confirmed and the package development view is displayed. By the time it is done, the reliability of the package is already guaranteed.

Further, since the package component information of the basic pattern has each component as a component group, it is not necessary to provide a basic pattern for each slight difference in component shape, and the number of basic patterns is reduced. It is possible,
It is not necessary to select a basic pattern from among an extremely large number of basic patterns. Therefore, the storage capacity for storing the basic pattern of the storage unit 2 can be reduced, and the selection process of the basic pattern by the calculation unit 4 and the designer from the plurality of basic patterns selected by the calculation unit 4 can be performed. This makes it easy to select the basic pattern and speed up the processing speed of the package design.

Further, the designer can select a component from the component group by exchanging the component or adding the component after the basic pattern is selected, and the designer can widen the range of selection, depending on the intention of the designer. You can design an approaching package.

[0065]

As described above in detail, according to the package design system of this embodiment, the designer can design the package only by the operation of inputting the basic information and the design information by the input means. You can In addition, the package is designed based on the inference rule information that defines a predetermined relationship such as the shape and size of each component and the coupling rule information that defines the coupling relationship between each component. In addition to being a package, the package conforms to the basic information and the design information, so that even an inexperienced designer can easily design the package.

Further, the component information indicating the components forming the basic pattern has at least a part of each component as the component group information. Therefore, the basic pattern is set for each slight difference of the component. The number of basic patterns can be significantly reduced as compared with the case where they are provided, and the selection work of basic patterns can be facilitated.
Further, when the basic pattern is selected, it becomes possible to select the component parts stored in the component part information as a component group in various patterns, which allows the designer to have a wider range of choices. Can be designed according to.
