  As described above, conventionally, when a plurality of flat plate-like components are arranged in multiple stages in the vertical direction to form a single package, a thickness that can secure a distance that the flat plate-like components positioned above and below do not contact each other is ensured. The provided support member is used for each flat part. For this reason, in the case of a package with a limited height, the stacking efficiency in the vertical direction cannot be increased due to the influence of the thickness of the support member.

  The present invention has been made in view of the above circumstances, and in a package that accommodates a plurality of flat plate-like parts positioned above and below so as not to contact each other by a support member, even if the number of the same number is the same as before, It is an object of the present invention to provide a packing body that can be packed at a low height and thereby improve the loading efficiency, and a packing method thereof.

  The packaging material according to the present invention is a packaging body in which flat plate-like components having openings are stacked in a vertical direction in multiple stages together with a support member in a state where corners are respectively supported by the support members. Stacked in parallel to form a stacked group, and the configured at least two stacked groups are arranged so as to cross each other, and the other in the opening of the flat plate component of one group constituting the stacked group The support member which supports the corner part of the flat plate-shaped component of this group is located, It is characterized by the above-mentioned.

  In the package according to the present invention, the flat plate components constituting the similar flat plate component group are arranged in a space between two flat plate components in the flat plate component group in the conventional package. Thus, the loading efficiency can be doubled while the packaging body is almost the same height as the conventional one. However, each stacked group is displaced in the horizontal direction, and the stacking efficiency in the surface direction is reduced by the amount of displacement.

In the package according to the present invention, the stacked groups are arranged so as to cross each other, in other words, displaced in the horizontal direction. Therefore, at the three corners in the flat plate component group in each group, the support members that also serve as the spacers can be stacked in the vertical direction as in the conventional case. However, since the flat plate component constituting the other group is located below or above the corner located in the plane of the flat plate component constituting the other group, the support that also serves as a spacer is maintained as it is. The member cannot be placed.

  Therefore, in the package according to the present invention, it is a necessary requirement that the flat plate-like component to be packed is a flat plate-like component having an opening in the region facing the one corner portion. Then, by positioning the support member for supporting the one corner in the opening, the support members for the remaining three corners can also be stacked in the vertical direction.

  In the package according to the present invention, the difference in height that allows the flat plate component constituting the other group to enter the space between the flat plate components constituting the one group is defined as the flat plate constituting each group. For this purpose, use different heights between the support member used for the lowermost layer group and the support member used for the upper layer group. Is required.

  In one aspect of the packaging body according to the present invention, the flat plate component constitutes a first stacked group and a second stacked group, and each flat plate component constituting the two stacked groups has the same shape. The flat plate component constituting the first stacked group is arranged in a posture rotated in the horizontal direction by 180 degrees with respect to the flat plate component forming the second stacked group. To do. In this aspect, the support member used for the first stack group and the support member used for the second stack group can be made common, and four types of support members that match the shapes of the four corners of the support member. There is an advantage that the required packing can be performed only by preparing.

  In a preferred aspect of the packaging body according to the present invention, the support member positioned in the opening is arranged in contact with an edge of the opening. In this aspect, a stable position where the support member positioned in the opening does not move freely in the opening can be ensured, so that the packing posture of each flat part in the packing body becomes more stable.

  In the present invention, the support member can be made of any material provided that it has the required cushioning properties and mechanical strength. Preferably, it is a foamed resin molded product from the viewpoint of moldability and lightness, and more preferably an in-mold foam molded product of a thermoplastic resin. Thermoplastic resins include polystyrene resins, polyolefin resins (eg, polypropylene resins, polyethylene resins, etc.), polyester resins (eg, polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate, etc.), polycarbonate resins, polyresins. Examples include lactic acid resins. Among these, it is preferable to use a composite resin containing polystyrene and polyethylene. The magnification of the foam may be appropriately set in consideration of the weight, shape, etc. of the part to be packaged, but is preferably about 30 to 50 times (0) from the viewpoint of good shock-absorbing property, light weight and economy. 0.033 g / L to 0.025 g / L). It can also be made by vacuum molding or injection molding using non-foamed resin.

  The present invention is a packaging method in which flat plate-like parts having openings are stacked in a vertical direction in multiple stages together with a support member in a state where corners are supported by the support member, respectively, as a method for hole of the above-described packing body. A plurality of flat plate-like components are stacked in parallel to form a laminated group, and the at least two laminated groups thus arranged are arranged so as to cross each other. A packaging method is also disclosed in which a support member that supports the corners of another group of flat plate-like components is disposed in the opening.

In one aspect of the above packing method, the flat plate component is configured as a first stacked group and a second stacked group, and each flat plate component forming the two stacked groups is a flat plate component having the same shape. Yes, the flat plate component constituting the first stacked group is arranged in a posture rotated in the horizontal direction by 180 degrees with respect to the flat plate component forming the second stacked group. Further, the support member positioned in the opening is disposed in contact with the edge of the opening.

  In the packing body according to the present invention, it is possible to pack components that are flat as a whole, such as a roof panel of an automobile, with high loading efficiency, particularly in the vertical direction.

  FIG. 1 shows a roof panel of an automobile as an example of a flat plate-like component 1 to be packed, which is substantially rectangular in a plan view and is slightly curved upward. In addition, an opening 2 is provided in a part of the surface. A plurality of the flat plate-like components 1 are stacked in the vertical direction without being in contact with each other in a flat posture, and a package A according to the present invention is obtained as shown in FIG. In packaging, the four corners of each flat component 1 are supported from below by first to fourth support members 4 to 7.

  Each support member 4 to 7 is an integrally molded product of foamed polystyrene in this example, and has the same height. The height of each of the support members 4 to 7 is such that when the four corners of the flat plate-like component 1 are supported by the support member and stacked in multiple stages, the upper and lower flat plate-like components 1, 1. Any height can be provided on the condition that there is enough space for another plate-like component to enter without contact and that the support member can be strong enough not to be damaged by the overload. However, in order to increase the stacking efficiency in the vertical direction as the package, it is preferable to set the height so that the space between the flat plate-like components positioned adjacent to each other in the vertical direction is as small as possible.

  Each of the support members 4 to 7 is substantially L-shaped in plan view, and on the inner side (entering corner side), recessed portions 41, 51, 61 having shapes substantially matching the shape of each corner of the flat plate-like component 1 are provided. 71 is formed. Except for the fourth support member 7, the outer surfaces of the other first to third support members 4 to 6 have a shape in which two side surfaces are orthogonal to each other. The outer surface 72 of the fourth support member 7 has an arc shape as a whole, which will be described later. Each support member 4 to 7 has an appropriate number of protrusions 43, 53, 63, 73 formed on the upper surface side, and the portions facing the protrusions on the lower surface side have notches 44, 54, 64 and 74 are formed.

  Hereinafter, the procedure for packing will be described. First, as shown in FIG.3 (b), the four support members 4-7 arrange | positioned at the lowest stage are divided into 2 in the horizontal direction in the appropriate place of a height direction. The upper four support members 4 a to 7 a divided into two are arranged in the case 20. In addition, as shown in FIG. 3A, the size of the case 20 in plan view is such that the support members 4a to 7a are obtained when the four corners of the flat plate component 1 are supported by the support members 4a to 7a. It is made larger than the outer shape made of.

  When arranging the four support members 4a to 7a, the first to third support members 4a to 6a are arranged along the two orthogonal walls 21 and 22 of the case 20, as shown in FIG. Deploy. At that time, the second support member 5 a is placed at the corner between the wall 21 and the wall 22 of the case 20, the first support member 4 a is placed along the wall 21, and the third support member 6 a is placed on the wall 22. Put along. If necessary, an appropriate support rod 30 is inserted between the first support member 4a and the wall 24 and between the third support member 6a and the wall 23, and the first support member 4a The position of the third support member 6a is stabilized.

  In that state, the flat plate-like component 1a that is positioned at the lowest position is formed by dropping the four corners into the recessed portions 41, 51, 61, 71 formed in the first to fourth support members 4a-7a. Put. The first to fourth support members 4 to 4 are arranged in consideration of the direction of the flat plate component 1a so that the opening 2 of the flat plate component 1a is close to the walls 21 and 22 of the case 20. 7 is set. The flat plate component 1a which is the lowest layer is the lowest flat plate component of the flat plate component group forming the first stacked group.

  Next, using the same first to fourth support members 4 to 7, the flat plate component 1b is arranged on the flat plate component 1a in a posture rotated in the horizontal direction by 180 degrees. The flat plate component 1b is the lowest flat plate component of the flat plate component group forming the second stacked group. As a pre-procedure, as shown in FIG. 4, the second support member 5 is placed at the corner of the wall 23 and the wall 24 of the case 20, and the first support member 4 is along the wall 23 of the case 20. The third support member 6 is placed along the wall 24 of the case 20. Then, the fourth support member 7 is placed in the opening 2 of the flat plate component 1a already placed so that the recessed portion 71 is on the inner side. Further, if necessary, appropriate support rods (not shown) are provided between the first support member 4 and the wall 22 of the case 20 and between the third support member 6 and the wall 21 of the case 20. By inserting, the positions of the first support member 4 and the third support member 6 are stabilized.

  Using the first to fourth support members 4 to 7 arranged in this way, the second corner from the bottom is dropped into the four recesses 41, 51, 61, 71 formed there. The flat part 1b is placed. Since the first to fourth support members 4 to 7 are higher than the first to fourth support members 4a to 7a supporting the lower flat plate-like component 1a, they are shown in FIG. Thus, the upper flat plate-like component 1b is in a state of being stacked on the upper level without contacting the lower flat plate-like component 1a.

As shown in FIG. 4 (a), the three corners of the upper flat plate component 1b are located outside the lower flat plate component 1a, and only one corner is the lower flat plate component 1a. It is located in the plane. That is, the two flat plate-like components 1a and 1b are arranged in a state of being shifted so that only one corner is positioned in the plane of the other flat plate-like component. And the corner part located in the surface is supported so that it may not move freely by the 4th supporting member 7 located in the opening 2 of the low-order flat plate-shaped component 1a. That is, the two flat members are integrally supported by the fourth support member 7 so that they cannot move freely with respect to each other. In the state shown in FIG. 4, the fourth support member 7 has an arc shape in which the outer surface 72 can be in close contact with the opening 2, and the corner portion can enter the recessed portion 71. Its size and shape are set.

And the third flat plate component 1c is placed on the first to fourth support members 4 to 7 supporting the second flat plate component 1b. The first to fourth support members 4 to 7 are stacked and the fourth flat plate-like component 1d is placed. As described above, the first to third support members 4 to 6 are positioned by the side wall of the case 20, and the fourth support member 7 is positioned by passing through the opening 2 of each flat plate member 1. Since they are stacked, the stacked postures of the two sets of the first to fourth support members 4 to 7 and the flat plate-like component 1 that are stacked are stabilized.

  Thereafter, by repeating the same process for the required number of sheets, as shown in FIG. 5 (a), as shown in FIG. The package A is completed, which is divided into C and each plate-like component constituting the two groups B and C is alternately arranged in the vertical direction. If necessary, finally, the two parts are arranged on the uppermost stage of the support members 4 to 7a stacked on the support members 4a to 7a supporting the first (lowermost) flat plate component 1a. The lower four support members 4b to 7b are placed. Thereby, as shown in FIG.5 (b), planarization of an upper surface is achieved. Finally, the case 20 is covered with a lid (not shown) and the whole is tightened with a band or the like to form the package A.

  As described above, in the package A according to the present invention, each flat plate component constituting the second stacked group enters the space between the two flat plate components in the first stacked group. The loading efficiency can be doubled while the packaging body is almost the same height as the conventional one.

  In the above description, the first stacked group and the second stacked group have the same shape as the flat plate parts, and one of them is packed in a posture rotated in the horizontal direction by 180 degrees. However, the shape of the flat plate-like components in the first stack group and the second stack group may be different from each other. In that case, it is necessary to prepare a support member having a shape corresponding to the shape of each flat plate-like component.
