Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates primarily to packaging boxes for transporting products, particularly to a packaging method using a Danl packaging box suitable as an outer container for household electrical appliances and the like that are heavy relative to their volume. It is something.

In general, packaging containers for products (objects) are suitable for transporting and selling them, and are suitable for the basic purpose of preventing damage and staining of the contents, for example, depending on the weight of the contents to be packed. In addition to using materials that have rigidity and rigidity, they are constructed to have a predetermined internal volume according to the shape and size of the contents, and are made of foamed plastic etc. in consideration of the impact resistance of the contents. It is common to use glue, film, and other materials in combination, but at the same time, in order to reduce packaging costs, especially for products such as home appliances that are mass-produced, it is necessary to simplify the packaging process, including the packaging process. Standardization, mechanization, and automation of work are also issues that are always desired.The present invention is based on the premise of such background problems regarding product packaging, and uses a material that is widely used as a material for packaging containers. The purpose of this invention is to provide a packaging method using a packaging axis as an extremely effective product outer container for the purpose of saving and optimizing the amount of materials used when using a single container, and for mechanizing and automating packaging work. .

As you already know, Dan? Although the box body has extremely high strength against compression, its rigidity against -1 bending cannot be said to be high. If the weight of the contents becomes large, the folded flags may deform and form a hole-in-the-bottom shape. Therefore, in conventional packaging boxes, the material is often designed to have enough rigidity to prevent the folded flag from deforming due to the weight of the contents. In terms of strength, the body of the box, that is, the side wall plates, is made of a material that is stronger than necessary, resulting in a waste of materials.

In addition, in order to improve the structural strength of the bottom of the packaging box, it has been considered not only to simply fold the flaps together, but also to glue the flaps together or mechanically fix them using stitchers, etc. However, even in this case, the rigidity of the flap cannot be reduced to a minimum of 2, and it is necessary to close the bottom opening of the packaging box, so it is possible to avoid having overlapping parts to some extent. 6) If you have to make the hula and pu longer, there is also the problem of attack.

Another problem with packaging methods using conventional packaging boxes is that, for example, it is not suitable for packaging products that are transported from an assembly line (products to be packed) using an automated or mechanized line. The problem is that it doesn't.

When storing and packing products in a packaging box that is shaped like a rectangular parallelepiped, in the conventional box described above, the bottom opening is first closed, and then a specified cushioning material is inserted through the open ceiling opening. Since the process of inserting the product and closing the open ceiling opening is necessary, it is difficult to suspend a heavy product from above inside the box.
For example, a blower device equipped with a vacuum chatter or the like with a predetermined vertical movement stroke is required, which leads to larger auxiliary equipment and double tracks, which is disadvantageous in terms of cost and is indispensable for packaging. This is because, due to the simultaneous insertion of the comb binding material, the insertion position of the comb binding material is also subject to significant restrictions.

The present applicant has conducted various studies on various problems in product packaging, and, taking into consideration the strength conditions of the packaging box, has developed a design that includes wall sections that are connected to form the four side walls of a rectangular parallelepiped, and・A box body with upper, lower, and lower flaps extending from the lower edge, and a rectangular flat plate that closes the bottom opening of this box body (and the ceiling opening is also separately K). We have developed a packaging box in which the lower flap is bent and fixed to the bottom surface of the bottom plate, and we have already applied for it.
When using a packaging box like this, which has been filed as No. It is now possible to take the procedure of inserting the box body and fixing the bottom flap to the bottom plate. In addition to making it possible to select materials that suit each design condition, the product can also be placed on the bottom plate without the constraints of the box body, which has the advantage of being extremely suitable for packaging automation and mechanization. It has been obtained.

The present invention relates to a packaging method using a packaging box formed by combining a basic KFi type of box body and a bottom plate, and is particularly suitable for line automation and mechanization.

This can be done for the purpose of saving thinner materials and expanding the selection range of various shapes and mounting positions.

In other words, if we further examine the relationship between the packaging box, product, frame, and material in this type of packaging, it becomes clear that 1. The one with the highest degree of overlap in the seed package is a
Regarding the strength of the LE board and the cushion interposed between the WE board and the lower part of the product, the upper part of the product can be used as a cushion material if the shape retention of the package and positional shift control are achieved. If the functions are satisfied to a certain degree, and if the product's support, shape retention, and positional shift regulation are satisfied, for example, in a product with a rectangular parallelepiped inner web such as a TV, the upper left and right sides of the rectangular parallelepiped are Since the cushions can be applied to the bottom left and right square parts and the cushions can be applied to the other parts, the amount of cushioning material needed to be used can be reduced. In the case of a type in which the upper and lower cushions are separated, if the lower cushion in contact with the bottom plate is fixed to the top surface of the bottom plate in advance, its position can be set with sufficient precision, and this lower cushion can be fixed to the top surface of the bottom plate in advance. Operations such as inserting and inserting the box body after placing the product on the fixed bottom plate, setting the upper extension bushing, etc. were done in consideration of the fact that they can be done with relatively simple automation 1 mechanized processes. Specifically, the gist of the present invention is to have wall portions connected to form the four side walls of a rectangular parallelepiped, and II! in parentheses. III
By folding the top edge of each side wall as a fold line
A box body formed by an upper flap that closes the ceiling opening, and a short lower flap extending from the lower end edge of each side wall as a fold line, and a rectangular shape that substantially matches the bottom opening of the box body; In addition, a bottom plate having a top surface or a plurality of bottom lines fixed thereto is prepared in advance, and a bottom plate and a bottom plate are fixed to the bottom plate.

The lower part of the packaged product is fitted into the recess formed in the bottom plate, and the packaged product is supported by the bottom plate. The packaging method is such that the bottom opening is closed and the ceiling opening is closed by folding it over the side of the upper cushion.Furthermore, the lower cushion seal is fixed to close the ceiling opening of the package. This packaging method uses a ceiling plate to which an upper cover is fixed in the same way as the bottom plate, and this is fixed by the upper flap of the box body.

The packaging method of the present invention will be specifically explained below with reference to FIG. 1 and the like showing the packaging process.

This shows the sequential process of the A-Hd packaging work shown in Figure 1, in which the product 2 (TV in this example) placed on the tray 1 is moved by a conveyor (not shown) K to positions Fi and B. The tray 1 is suspended stationary by a simple hanger device or clamping means from the left and right sides, and in this state, the tray 1 is moved from below the product 2, and the box chest (to be described later) is placed below the product 2. A bottom plate 3 having a shape matching the bottom opening is introduced. This F& plate 3 has a pair of opposing construction bushes each having a recess 4a into which the lower corner of the product 2 is fitted.

The bottom plate 3 having the lower cushion 4.4 is raised toward the bottom of the product 2 which is in a stationary suspended state, with the bottom plate 4.4 fixed in advance by adhesive or the like at a predetermined position IIItK on the upper surface of the bottom plate,
The recessed portion 4 m + 4 a is fitted into the lower part of the JI 12.

When the product is transported in this state (see Figure 1 C) and reaches position D, the main body of the packaging box made by Dangi-h is folded and stored in a separate 4-Cm (not shown). A box body 5 forming a box shape is taken out one by one by a set-up caser (not shown), and is fitted into the product 2 (above the product 2), which is set up in a KW body to form a box shape. inserted.

This shaft body has 5 pieces, and 1 piece @ wall plate 6 made of rectangular parallelepiped four side wall tubes.
, a short lower flap 7 extending downward with the lower edge of each side wall plate 6 as a fold line, and an upper flag 8 extending upward 73 with the upper edge of each side wall plate 6 as a fold line,
In this example, this upper flap f8 is folded to close the ceiling opening, and the folded shape #'i-
It is not limited to the format shown.

Next, with the outer periphery of the box Iis covered, there is a product handling and specification information inside the box, and a message that is fitted to the upper corner of the product 2 and between the inner surface of the box and the ceiling cover and the product. Insert the upper part and shin (not shown) that serve as a kink.
1E), the lower flaps 7, 7, . . . are folded along the fold lines and attached to the lower surface of the bottom plate 3 with oil, while the upper flaps 8 are folded to complete the packaging (see FIG. 1C).

In addition, in the process shown in FIG.
The operation for gluing 17 is to attach the bottom plate 3 as shown in Figure 1g2.
Since it is highly rigid, the entire product can be sufficiently supported by the support stand 9 such as a conveyor even if the area around its periphery is left unused. This can be done using an automated device while it is placed on the support stand 9 of the conveyor. Also, the fixation may be done with adhesive or mechanical fixation such as steel, char, etc. Figure 1 H shows the bottom of the packaging box after packaging is completed. There is.

In the above process description, the usual processes that are carried out in this type of packaging work, such as covering the product in one position with a Pg bag as the primary packaging, may be carried out as necessary (and Prior to fitting the box body 50, an upper extension cushion is placed and fitted on the upper part of the product, or the shaft body 5 is surrounded by the support base of the conveyor as described above, and the shaft body 5 is placed in the lower direction t in a closed state.
After that, the product 2 and the bottom plate 3 may be moved and supported on the support stand, and the box body 5 may be inserted from below the product 2. ) The packaging box used as the product's outer container formed by the above procedure should be selected as a material with high rigidity for the bottom plate depending on the weight of the product, and on the other hand, By forming the outer circumferential shape of the bottom plate to match the bottom opening of the box body, which has an internal volume determined by the shape and size of the item, when the package is suspended, the box can be closed by the lower flanges and de. III of the box trunk from the bottom plate attached to the trunk 1fBKm1! (Only tensile force is transmitted to @), but since the step has a high tensile strength as a single layer material, the required strength is small, and the bottom flap is short, so the O dimension of the box body There is also the advantage that it is easier to remove. Also, in terms of the shape retention of the box body, the packaging of this invention I! has advantageous characteristics. In other words, packaging boxes with single-layered tiers generally have poor shape retention against horizontal forces, causing the four sides to twist like a parallelogram, but in the packaging box described above, Since a bottom plate having a shape that matches at least the low opening of the box body is incorporated, it has an advantageous configuration for preventing such twisting movement, and the ceiling opening faK% described above is advantageous for preventing such twisting movement. It is even more effective in the case of packaging boxes that use the same type of ceiling board.

FIG. 3 shows an enlarged view of the lower cover 74.4 and the bottom 3 which are fixed together in advance in the above-described packaging method. In this example, the product to be packed is a rectangular parallelepiped T-shaped TV. Therefore, the recess 4 into which the lower corner of the product fits
A pair of opposing lower cushions 4, 4 having a diameter of 1.5 m and 4 at. 10.10. It is clear that it is also possible to fix the ... to a predetermined position on the upper surface of the bottom plate 3.Using such a type of glue or thread is difficult to set the position by the mounting in the conventional packaging method. Although it is extremely difficult to automate and mechanize, the method of the present invention does not have that difficulty and can fully perform the function as a remote control. Since it is possible to limit the shape and size of the material, it is effective in saving materials and lowering costs.

Note that the shape, number, etc. of the upper extension bush may be selected as appropriate.

The fifth button shows a developed view of the box body 5' forming the packaging shaft used in another embodiment of the present invention, and in this example, the four side wall plates 6
'..., upper and lower KMi-sized flaps 7'.

By extending the top plate 8' and using the top plate 11 together with the bottom plate, a packaging box is formed, but since the top plate 11 does not support the weight, its strength is limited to the container itself. It is thought that there are almost no problems, and it may be sufficient to extract the contents from the outside air. 9' This is the adhesive allowance for forming the body of the welfare box. 60 is shown in the developed view of Figure 5. The figure shows the state in which the body of the leading box is assembled and inserted into the bottom plate 3' on which the product 2' is placed.

In this example, a pair of upper and lower columns 12 are fixed in advance to the lower surface of the ceiling plate 11, and form the upper and lower parts of the product 2 in the same shape as the bottom plate 3I@. ′ is sandwiched between the top and bottom.

Note that the upper cushion may be separate and independent from the ceiling board.

FIG. 7 shows the configuration of a packaging box in the form of a mourning example shown in FIG. 4#, upper side, and 14@- respectively], each of these cushions 4'', 14KFi has an arc-shaped recessed portion formed therein. This is effective as a packaging shape for a product having a special non-rectangular shape such as a cathode ray tube, and the packaging can be automated and mechanized in substantially the same manner as in the embodiments described above.

In addition, in each of the above embodiments, the number of holes in the leg of each box is 11!
The flap (or the upper extension flap) is bent and attached to the lower surface (upper surface) of the bottom plate (ceiling plate), but this can be attached or fixed to the bottom plate or ceiling plate side if necessary. a flap for securing extends from the edge;
On the other hand, if the lower flange of the box trunk KFi or the upper extension flange is measured, it is possible to bend the bottom plate, etc., into contact with the outside of the tube shaft m part and press it to adhere and fix it. It's natural.

Honey-shaped like this! 111s has an advantageous strength condition on the bottom plate side because the weight of the packaged product on the bottom plate acts as a shearing force on the bonded/fixed part, but on the other hand, the appearance of the box body is To solve the problem of aesthetic problems due to the appearance of smudges and smudges on the surface of the surface, it is advisable to adopt them as necessary, in conjunction with the selection of materials, etc.

As described above, in the packaging method of the present invention, in order to satisfy the strength conditions of each component of a conventionally known one-tier packaging box, each of these components is configured by a printing part #, and This type of packaging box is not only a combination of these separate parts, but also a combination of these parts in a specific relationship, which provides excellent strength and shape retention, and also eliminates waste of materials. It has the advantage of being suitable for mechanization and automation of packaging operations when used as a packaging container, and its usefulness is extremely great.
