Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a container design system that uses a computer to automatically design the structure of containers such as paper cartons and corrugated pole boxes.

[Prior Art] Traditionally, the work for structurally designing containers such as paper cartons and cardboard boxes involves determining the contents, basic dimensions, paper quality, paper thickness,
A method in which experts with extensive design experience draw rough drawings or developed drawings directly on paper based on their own experience, taking into account the various conditions for the box, such as the customer's filling machine and preferences. , a method of introducing a CAD system and inputting two-dimensional coordinates with a tablet or mouse, etc. to digitize the development drawing, and a method of digitizing the development drawing from the main body pattern section and the component pattern section that have additional data such as parameters of dimension values for each part in advance. A blank sample is created at the time a developed diagram is created by attaching and replacing parts using an authorized basic pattern and inputting parameter values for dimension values based on the expert's own experience.

Furthermore, if this sample is not actually assembled, it will be determined whether the form, size, etc. of the box are satisfied.
If the created sample was not satisfactory, the process of revising the development drawing was repeated.

[Problems to be Solved by the Invention] However, the conventional design method as described above has the following various problems. In other words, it is difficult for anyone who is not an expert (designer) with extensive design experience to carry out the design, and what is more, the expert must develop the concept of the form of the box when creating the development drawing, and then use other human resources to create the design. We use a structural design method that involves repeating tasks such as inputting two-dimensional coordinate values, dimensional parameter values, etc. into the CAD system, creating and modifying developed drawings by hand, and creating blank paper samples, etc. by trial and error by experts. , consuming effort and time.

The present invention was developed to solve the above-mentioned problems, and it aims to significantly shorten the labor and time involved in the structural design of containers such as paper cartons and cardboard boxes. Structural design can be easily done by anyone, even non-experts, and it also gives the designer an idea of the desired container form, supports structural design of containers with many variations, and actually assembles blank samples. The purpose of the present invention is to provide a container design system in which judgments on the form, size, etc. of a box, which could not otherwise be made, can already be made at the time a developed diagram of the box is prepared.

[Means for Solving the Problems 1] In order to achieve the above-mentioned object, the present invention provides an input means for inputting at least basic information and design condition information, information on the structural form of the container, information on component parts intended for use, and combination of components. a storage means for storing rule description information and rule description information for inferring the structural shape of the container as a database; a display means;
determining a desired container shape by searching container structural form information, usage component information, and component combination rule description information stored in the storage means according to input information from the input means; and an arithmetic processing means having a function of inferring the structural shape of the container based on these search results and determination results and displaying the inference result on a display means, and outputting the inference result obtained by the arithmetic processing means. This is a container design system characterized by comprising: an output means for

[Operation] Therefore, in the container design system of the present invention, when basic information, design condition information, and if necessary management information are input from the input means, the information is stored as a database in the storage means based on this input information. Search the structural form information, intended use component information, and component combination rule description information of the container representative of the contents in the container to determine the form of the container desired by the designer, and based on these search results and determination results. Based on this, the structural shape of the container is inferred, and the inference result is displayed on the display means. Then, the inference result obtained in this way is outputted by the output means.

[Example 1] Hereinafter, the present invention will be explained in detail with reference to examples shown in the drawings.

FIG. 1 is a block diagram showing an embodiment of a structural design system for containers such as paper cartons and cardboard boxes (hereinafter simply referred to as boxes) according to the present invention. As shown in FIG. 1, the system of this embodiment includes an interactive input means 1 consisting of a keyboard, a mouse, etc., a storage means 2 consisting of a magnetic disk device, etc., a display means 3 consisting of a color graphic display, etc.
It consists of an arithmetic processing means 4 consisting of an engineering workstation, etc., and an output means 5 consisting of an XY plotter, a cutting machine, a magnetic disk device, etc.

Here, the input means 1 includes basic information (box structure related to contents and purpose of use, paper white, size display unit, etc.), minimum design condition information necessary for structural design (basic dimensions, paper quality,
(paper thickness, filling machine, etc.), management information (customer name, product name, development drawing number, etc.) for managing data when registering after structural design is completed, and other information.

In addition, the storage means 2 stores, as a database, structural form information of the box representing the contents, intended component information, component combination rule description information, rule description information for inferring the structural shape of the box, and other information. It is something to do. In this case, the structural form information of the box representing the contents is as shown in Figure 3. For example, the basic information is classified by the contents to be placed in the box, such as soap, confectionery, medicine, clothing, etc. Information about which box is most suitable for the input contents and its structural form are registered. Intended use component information refers to the structure of the box related to the intended use of the box entered in the basic information, for example, the box structure that is related to the intended use of the box that is automatically selected for the contents. When selling a product, the purpose is to allow consumers to see the contents from the outside of the box, or to make it portable. In addition, in response to the information that the purpose is to lock the box when inserted, in order to change the structure of the box according to that information, we changed the component parts to the basic structural form. This registers information on whether or not they should be combined and the form of the component parts. Component combination rule description information describes the components that must be combined in order to change the structure for the purpose of use, with respect to the basic structure of the box that is automatically selected based on the contents entered in the basic information. This is information that describes rules regarding the combination of components and describes the rules for each component.

Furthermore, the rule description information for inferring the structural shape of the box is
Design conditions (basic dimensions, paper quality, paper thickness, filling machine, etc.) that have been input using the input means for the box structure determination result determined by the designer by simulating the input information and box structure form.
This is information that describes rules for determining whether or not an object will actually become a box, taking into consideration the following, and for performing processing to actually become a box.

On the other hand, the arithmetic processing means 4 calculates, in accordance with the basic information from the input means 1, structural form information of a box representative of the contents stored in the storage means 3, usage purpose component information, component combination rule description information, A database search function that searches for rule description information and other information for inferring the structural shape of the box;
A function that determines the structural form of the box desired by the designer according to basic information, and a function that determines the form of the box that the combined parts form based on the component combining rule description information. A function that automatically checks whether or not the results are satisfied, and the box shape results are compared with the design conditions (basic dimensions, paper quality, paper thickness, filling machine, etc.) that have already been input using the input method. A structural design inference function that takes into account the rule description information for inferring the structural shape, determines whether it will actually become a box, processes it to become an actual box, and calculates the shape of the box based on the design result. It has a fine-adjustment function that allows changes, changes in dimension values, etc. to be corrected while using the structural design inference function again, and a display function that allows the display means 3 to display the design results.

Further, the output means 5 outputs the design result obtained by the arithmetic processing means 4.

Next, the operation of the container design system configured as above will be explained according to the flowchart shown in FIG. 2.

First, from the input means 1, basic information (structure of the box related to contents and purpose of use, paper size, dimensional display units, etc.) and the minimum necessary design condition information necessary for structural design (basic dimensions,
When the paper quality, paper thickness, filling machine, etc.) are input, based on the input contents, from the structural form information of the box representing the contents stored in the storage means 2 as a database,
The optimal structure of the box for the contents is searched by the arithmetic processing means 4 and displayed on the display means 3 based on the data. Then, based on the structure of the box related to the input purpose of the box, components related to the purpose of use are searched from the intended component information stored in the storage means 2 as a database. Accordingly, a next process selection is performed from the input means 1, in which the arithmetic processing means 4 searches the component combination rule description information for rules regarding the combination of component parts related to the purpose of use.

If the above-selected item is determining the structural form of the box, the designer should consider the optimal structural form for the contents being displayed and the In other words, in order to take into consideration the structure of the box for the purpose of use), according to the instructions from the computer, the display means 3 interactively displays instructions on the screen, such as what form and where of the components related to the purpose of use, etc. Through these processes, it is possible to determine the structural form of the box desired by the designer, and when this process is completed, the process returns to the next process selection. At this time, the component combination rule description information already retrieved by the arithmetic processing means 4 is used to determine whether or not the combined components satisfy the form of a box as instructed by the designer. For example, as shown in Figure 4, if the designer inputs the item that the purpose is to lock the box when it is inserted, in the basic information, If there is a rule that cover panels, cover tucks, and cover flaps are connected by components that also have an insertion lock function, or if the item is intended for portability, the designer must specify the components to be connected (this case,
We have prepared rules for the form of the box, such as the rule that if the components are not connected to the left-right symmetrical plane of the box panel (the handle is a hole), it is against the functional use of the box, and if the designer If an action that violates the above-mentioned rules is performed during the ξ-ratio on the screen, an error message is displayed on the display means 3, and the designer is notified of the error in the structural design in advance. .

In addition, if the item selected in the next process selection is a design condition change, the minimum design conditions (basic dimensions, paper quality, paper thickness, filling machine, etc.) required for structural design that have already been input from input means 1 will be added. For example, if the size of the contents in the box has changed and you want to change the basic dimensions and redo the design, you can input some of the conditions through the input means l. The design conditions can be changed by

When this process is completed, the process returns to the next process selection.

Next, once the form of the box desired by the designer has been determined as described above and the minimum design conditions necessary for structural design (basic dimensions, paper quality, paper thickness, filling machine, etc.) have been determined, the next processing begins. Next, from the selection process, it is determined whether the box resulting from the form determination actually becomes a box by considering the design conditions, and structural design reasoning is performed to perform the processing to actually become a box.For example, design Is it possible to realize the form of the box determined by the person with the properties and thickness of the paper specified in the design conditions? If a filling machine specified in the design conditions is used, the characteristics and filling speed of that machine must be considered. This process takes into account the structural shape of the box.

In order to perform this process, the arithmetic processing means 4 searches for rule description information for inferring the structural shape of the box, which is stored as a database in the storage means 2, and based on this, the arithmetic processing means 4 performs inference. It will be done. Then, the design result (that is, a developed view of the box including outline line/bending line information, dimension line/dimensional value information) is displayed on the display means 3. If you wish to make some changes to the shape of the box or dimension values for the displayed inference results, use the input means 3 to select the fine adjustment function and display it on the display means 3. Instructions are given to the design results, structural design inference is performed again by the arithmetic processing means 4 while taking into account changes, and the design results are displayed again on the display means 3. For example, if you want to increase the height of the flap a little In this case, if you specify the numerical value of the dimension value of one flap from the display screen, change the dimension value, and perform structural design inference again, you may find that parts of the same shape as the changed flap are connected, When cover panels and cover tucks related to flaps are combined, the dimension values of related parts are automatically changed and displayed in accordance with the changed values. Finally, several design inferences and displays are performed in this way, and an instruction is given to register the obtained design results. When finally registering, input method 1
Management information of design results (customer name, product name, development drawing number, etc.) is input to the display means 3 through the display means 3.

Next, the output means 5 outputs the design results and management information as described above. For example, the output means 5
If it is a plotter, it will automatically output a developed drawing of the box, or if it is a canting bronchter, it will automatically output a blank sample.

Similarly, it is also possible to output a block mount, which is required when creating a block.

As described above, in the container design system of this embodiment, the structural form information of the box representing the contents, the intended component information, the component combination rule description information, and the rule description information for inferring the structural shape of the box are stored in the data directory. This makes it possible to design the box structure in an extremely short amount of time, unlike traditional manual design. In addition, basic information (box structure related to contents and purpose of use, paper white, size display unit, etc.) and minimum design condition information necessary for structural design (basic dimensions, paper quality, paper thickness, filling machine, etc.), etc. The designer only needs to provide simple information and simulate the structural form of the box desired by the designer, so not only experts with extensive design experience, but also people with little design experience can easily use it. Optimal structural design can be carried out quickly and accurately. Furthermore, after the structural design is completed, we can obtain tools such as an exploded view of the box and a blank sample. In addition, by expressing the designer's desired box structure concept on the Graphita display rather than in his or her head, it allows the designer to visualize the box structure and supports structural design with many variations, making it possible to create designs that are not possible without actually assembling a blank sample. It is now possible to make judgments about the form, size, etc. of the box that were not available at the time the exploded view of the box is created.

[Effects of the Invention] As explained above, according to the present invention, it is possible to significantly shorten the labor and time involved in designing containers such as paper cartons and cardboard boxes, and it is possible to do so without the need for experts with extensive design experience. Anyone can easily design the structure, and it also gives the designer an idea of the desired structure of the container, supports structural design with many variations, and is not possible without actually assembling a blank sample. It is possible to provide a container design system that makes it possible to determine the form, size, etc. of a container at the time when a developed view of the container is prepared.
