Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cardboard packaging specification design support system for supporting specification design of a cardboard box for packing a product.

[0002]

2. Description of the Related Art Conventionally, the design of product packaging specifications is based on the form and material of the outer corrugated cardboard, the form and material of accessories (partitions) attached to the outer corrugated cardboard, and the number of stacking steps. This was done based on the accumulated data. In addition, the cardboard box (package) in which the product is packed deteriorates due to factors such as cardboard production, storage, storage, aging, and storage temperature and humidity conditions. And the number of stacking stages. At that time, the safety factor is usually designed to be three times or more,
At present, it varies greatly from about 2 to about 11.

Here, a calculation flow in the conventional specification design is shown (see FIG. 16). The data used for the calculation is
L (depth) and W (width) dimensions of outer box, packing mass,
This is the assumed number of display steps (the maximum number of stacking steps assumed). 1. Required strength calculation: {necessary strength = packed weight × (estimated number of display steps−1)} (step S01); 2. Exterior strength calculation (material is arbitrarily set): calculated from L and W using a conversion table (step S02); Safety factor calculation: {Safety factor = Exterior strength / Necessary strength} (Step S03) are sequentially performed.

[0004] When the safety factor is less than three times (when the determination in step S04 is No),
Recalculation is performed (return to step S02). On the other hand, when the safety factor is three times or more (No in the judgment of step S04)
Is determined), the exterior specification is determined based on the data (step S05).

[0005]

Conventionally, specifications were designed as described above, but due to differences in the experience of the practitioners, the cost was increased by using corrugated cardboard made of a material having excessive strength or quality. Or, on the contrary, a low strength specification was set, and problems such as crushing of a cardboard box occurred. Further, in the case of a product having a partition, its strength was not taken into account in the calculation, and the exterior strength was excessive. The safety factor of the cardboard box designed in this way is 2 to 2 as described above.
At present, there is a large variation up to about 11, and the maximum value of the required strength has not been a significant factor for the design.

[0006] Also, the difference in the individual packaging form (container form) has not been reflected in the specification design of the cardboard box, and the cost has been increased since before. This is, for example, when products using pouches etc. are packed, it is designed to maintain strength only with cardboard, but when products using bottles etc. are packed, the individual packaging itself has strength. In addition, although the material of the cardboard can be reduced, the cardboard is also designed to maintain the strength similarly.

The strength is calculated by using a conversion table based on the dimensions of L (depth) and W (width) of the exterior (the material is arbitrarily set). It is not at present. Further, only the A flute was targeted, and the calculation for each flute was not performed.
Conventionally, calculations were not made when different materials were used for the front liner, the back liner, and the core.

In addition, no pass / fail evaluation has been made on the exterior material finally determined by calculation. In addition, the setting of conditions for handling cargo has not been standardized, and there have been varieties of poor transport efficiency such as incapable of efficiently storing when loading on a transport pallet or loading on a truck. Also, the relationship between the exterior material (strength) and the handling conditions was not clear, and some parts were overdesigned.

The present invention has been made in view of the above points, and allows an appropriate exterior material to be selected based on the form of the container to be packed, the form of the exterior including the partition, and the dimensions thereof, and the design of the exterior can be made. An object of the present invention is to provide a cardboard packaging specification design support system that enables appropriateness and standardization.

Further, in the cardboard packaging specification design support system of the present invention, an (estimated) price corresponding to the material of the corrugated cardboard and the form and size of the corrugated cardboard box is further stored, and the lowest cost cardboard box including a partition is provided. It is more preferable to select the specifications.

In the cardboard packaging specification design support system according to the present invention, the strength of the cardboard box is used as a value of a square root of a value obtained by multiplying the sum of the width and the depth of the cardboard box by the thickness. The strength of the material based on the material and the flute of the cardboard, a predetermined constant, and the exterior shape factor corresponding to the form of the cardboard box are determined by multiplying the total length of the partition by the thickness.

The form (shape) of the corrugated cardboard box contributes to the strength for each form (formula A, B, Hbox, wrap, 2-pack, etc.) of the form of the corrugated cardboard box in the form factor DB · 2b for the form of the package. The exterior shape factor (0.8

The program may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. Here, the "transmission medium" for transmitting a program refers to a medium having a function of transmitting information, such as a network (communication network) such as the Internet or a communication line (communication line) such as a telephone line. Further, the program may be for realizing a part of the functions described above. further,
What can realize the above-mentioned function in combination with a program already recorded in the computer system, that is, a so-called difference file (difference program) may be used.

The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and the configuration and the like may be made without departing from the gist of the present invention. included.

[0073]

As described above in detail, according to the present invention, not only the strength of the cardboard box itself, but also the effective strength of the individual package to be packed and the strength of the partition. In addition, considering the exterior form and partition form, the total strength is calculated and the safety factor is calculated, so it differs from the conventional design of the exterior specification based on the strength of the standard cardboard box, which is more appropriate. The exterior design can be designed. Further, according to the present invention, it is possible to automatically determine the combination of the material of the cardboard box and the material of the partition whose safety factor is within the standard range. Further, by setting the range of the reference safety factor in consideration of the form of the container of the product to be packed, it is possible to set a more appropriate reference more finely. Further, according to the present invention, when designing the specifications of the exterior having a necessary safety factor, the condition of the handling is also satisfied, so that the relationship between the exterior material (strength) and the handling conditions is conventionally clear. The problem that was partially over-designed can be solved.
