BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pallet box used exclusively for transporting a large amount of unfinished products and parts from a manufacturing factory to an assembly factory.

[0002]

2. Description of the Related Art A conventional pallet box is mounted on a pallet having a space for inserting a fork under the board.
An integrally assembled packing member such as a wooden frame or a rectangular carton is used. In the case of a wooden frame, a long plate was arranged in a matrix in the vertical and horizontal directions to form a frame, and in the case of a carton, a cardboard box for packing was used. However, such a pallet box is tough because all the combined parts of the wooden frame are joined by nailing, but it is forcibly peeled off because the disassembling work to pull out each nail is troublesome. , It is sometimes broken and sometimes damaged. Therefore, all dismantled items are discarded without being reused. Corrugated cardboard cartons are tough even though they are limited, are easily damaged during stacking, and are disposable after each transport. The cost is high. Therefore, as described in Japanese Utility Model Laid-Open No. 42137/1993, the present inventor has made a pallet having a space for inserting a fork on the bottom surface of a substrate, a rectangular parallelepiped carton to be mounted on the pallet, and closely contacting the inside of the carton. Then, we proposed a pallet box composed of reinforcing frames arranged in parallel at appropriate intervals. Its structure is shown in Fig. 5, and the reinforcing frame is composed of only a plurality of rectangular supporting frames 6, 6 ... In which long plates having a length corresponding to each inner dimension of the height and width of the carton are combined in both shapes. It is configured and arranged in the carton 5 at right angles to the longitudinal direction, and is fixed to the substrate 2 of the pallet 1 together with the bottom plate of the carton 5.

[0003]

[Problems to be Solved by the Invention] Since the introduction of a pallet box incorporating a rectangular support frame in the carton, not only the workability has been significantly improved, but also the awareness of recycling has been increased, and the result has been It was more than expected. However, in addition to boxed standard products, lightweight large parts and small heavy items, as well as small bagged parts, are indiscriminately loaded in the carton, which makes the weight balance unstable. Cheap. Especially when stacking several stages,
Sufficient strength is secured in the vertical direction,
There is no problem as long as it is stacked in a warehouse where external force is not applied, but when it is loaded on a truck or loaded on the bed of a truck, it is tilted during transportation or receives an unbalanced load due to vibration and a rectangular support frame. There is a risk that the product cannot be held by itself and the load collapses. If a reinforcing member is added, the strength will be increased, but if it is added, the number of members will increase and the cost will increase, disassembling and assembling will be complicated, and it will be bulky when returning.

[0004]

DISCLOSURE OF THE INVENTION The present invention is a pallet box which has succeeded in minimizing the number of members of the reinforcing frame and yet increasing the strength thereof, and its structure is
The reinforcing frame is composed of a plurality of gate-type support frames whose upper ends are connected to each other by a top plate and a plurality of cross girders erected on the gate-type support frame. Are arranged in parallel at appropriate intervals, and the lower ends of the gate-shaped support frames are integrally fixed to the bottom plate of the pallet together with the bottom plate of the carton, and then the gate-shaped support frames are connected to each other by a cross beam. . A lattice-shaped structure is adopted for the substrate of the pallet.

[0005]

[Operation] The gate-type support frame bears the vertical load and the impact on the corners, and the girders support the unbalanced load in the horizontal direction. Therefore, the randomly packed packages in bulk are danced or moved in the carton. However, it does not cause a load collapse.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A pallet box according to the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 is a pallet, and each of the vertical plates 2a, 2a ,.
In parallel with the above, bench rib type legs 3.3.3 are integrally provided, and a fork insertion space 4 into which a fork can be inserted from the front, rear, left and right is secured in the lower portion of the substrate 2. Reference numeral 5 denotes a carton. The carton 5 is formed of a single corrugated cardboard paper by a punching plate in which a side plate and upper and lower flaps are continuously arranged, and is assembled into a rectangular parallelepiped having a size that can be placed on the pallet 1. The carton 5 is made of the same material as the conventional one, but by adopting a synthetic resin or water-resistant corrugated board, it is possible to prevent the strength from being deteriorated even if it gets wet with rain.

Reference numeral 6 denotes a gate-shaped support frame, which connects the upper ends of the long plates 6a, 6a, which are columns, with the long plate 6b, which is a top plate, and which is orthogonal to the carton 5 in the longitudinal direction. The sides are in close contact with each other, and the upper part is formed to have a size capable of ensuring a gap corresponding to the thickness of the long plate when the upper flap of the carton 5 is closed. This gate-shaped support frame 6 is shown in FIG.
As illustrated in FIG. 2, it has a dovetail type joint structure composed of a dovetail-shaped tenon 7 formed on the upper part of the long plate 6a and a tenon 8 formed at both ends of the long plate 6b, and can be separated with one touch. They can be combined and have a good reputation for the reliability of the degree of coupling at the time of combination. Nail 9 is stapled on the inner surface of the lower end of the long plate 6a.

10 is a cross beam made of a long wooden plate,
The length of the carton 5 is an inner dimension in the longitudinal direction, and the cross girder 10 and the gate-shaped support frame 6 constitute a reinforcing frame. To assemble the pallet box formed as described above, the carton 5 is set on the substrate of the pallet 1 with the upper surface opened, and the long box 2b, which constitutes the substrate, is placed inside the carton 5. The gate-shaped support frame 6 is set so that the plates 6b are arranged in parallel, and the nails 9 that are stapled together are fixed to the base plate 2 of the pallet together with the bottom plate of the carton 5 (FIG. 3). Since the nail 9 is stapled to the inner surface facing the lower end portion, the nail 9 can be easily nailed even when fixing the gate-shaped support frames arranged at both longitudinal edges of the carton 5. The gate-shaped support frame may be set only on both longitudinal edges of the carton 5. Along the inner surfaces of the carton 5 on both sides in the longitudinal direction, the cross girder 10 is provided with the gate-shaped support frame 6,
Place on top of 6 ... and fix with nailing (Fig. 4). Here, instead of nailing, bolting may be performed.

When the assembly of the reinforcing frame is completed, the packing is completed simply by packing the baggage and closing the lid of the carton 5. If necessary, the flaps serving as the lids are fixed with staples or gum tape so as not to open. . The cross beam can also be assembled after the luggage is stored. Since a reinforcing frame is arranged on the inner surface of the carton 5, the strength is high.
By adding 0, the structure becomes strong against an unbalanced load. Of course, it has sufficient strength for stacking. When the carton is large, a reinforcing cross girder can be added between the pair of left and right cross girders or on the inner surface of the carton, or the reinforcing frame can be integrated.

The pallet box can be easily lifted up and down using a forklift or the like, and the pallet box which has been transported is disassembled after taking out the load. In that case, if you adopt a joint structure at both corners of the reinforcing frame, you can easily separate the gate-type support frame and the cross girder by carefully pulling out the nails, and return it with the pallet for reuse. You can

The pallet of this embodiment is light in weight because the substrate has a lattice structure and is excellent in workability of disassembly and assembly. Moreover, since there is a space between the legs, the back surfaces are slightly offset from each other. If they are combined facing each other, the thickness will be reduced, and the volume when returned will be halved. Although the portal-type support frame of this embodiment adopts a joint structure with a stool, the connecting portion between the support and the top plate is not limited to that, and may simply be butted and nailed. , Pallet, carton material,
The size, the width and number of the reinforcing frame, and the shape of the fork insertion space formed in the lower portion of the bottom plate may be appropriately changed.

[0012]

According to the present invention, since the reinforcing frame is composed of the separable gate-type support frame and the cross girder, the recycling is facilitated, so that the recovery rate of the packing material is increased and the packing material is transported. It leads to cost reduction. Moreover, since the structure can sufficiently withstand the lateral lateral load, there is no fear of collapse of the load.
