Description

  The present invention relates to an exterior body that exteriorizes a pallet used for storing or transporting articles.

  When transporting or storing products, pallets such as post pallets and box pallets may be used. The post pallet is provided with a bottom structure and a column that is erected from a corner portion of the bottom structure. The box pallet includes a bottom structure and a peripheral wall standing from the peripheral edge of the bottom structure, and the peripheral wall is often configured in a mesh shape, a lattice shape, or the like. When the product is stored in such a post pallet or box pallet, the product is exposed to the outside. For this reason, an exterior body may be used for the purpose of waterproofing and dustproofing the product in the pallet (Patent Document 1).

  The exterior body disclosed in Patent Document 1 is a box-shaped body, and a product once stored in the box-shaped body is placed on a box pallet. This protects the product from the outside. There is also a method of covering the pallet with a cover-shaped exterior body. That is, as shown in FIG. 12, a bag-shaped exterior body 102 having five surfaces corresponding to the peripheral wall and the upper surface of the post pallet 100 is covered with the post pallet 100. This prevents the product (not shown) stored in the post pallet 100 from being exposed to the outside, thereby protecting the product.

By the way, when products are transported, in order to improve transport efficiency, save space, and the like, as shown in FIG. 12, so-called stacking is often performed in which the post pallets 100 are stacked vertically. That is, the post pallets are stacked in the vertical direction by superimposing the lower end of the column 101b of the other post pallet 100b on the upper end of the column 101a of one post pallet 100a.
Japanese Patent Laid-Open No. 5-124640

  However, in the case where the bag-shaped exterior bodies 102a and 102b are covered with the post pallets 100a and 100b, the upper end portion of the column 101a of one post pallet 100a (lower post pallet) is hidden inside the exterior body 102a. For this reason, when stacking, the position of the upper end of the column 101a of the lower post pallet 100a is not visible, and the upper end of the column 101a of the lower post pallet 100a and another post pallet 100b (upper post pallet). It took a long time to confirm the position in the overlapping with the lower end of the column 101b. In some cases, the upper post pallet 100b may fall due to the position of the upper end of the column 101a of the lower post pallet 100a being shifted from the lower end of the column 101b of the upper post pallet 100b.

  Furthermore, as shown in FIG. 13, the exterior body sandwiched between the upper and lower columns 101a and 101b is likely to be deformed due to compression by the columns 101a and 101b, friction due to vibration during transportation, and the like. As a result, there is a problem that water or dust from the outside enters the post pallet and cannot protect the product due to a crack generated from this part and the exterior body being torn.

  In view of the above problems, the present invention provides an exterior body that can easily perform pallet stacking work and can exhibit a stable function over a long period of time.

The exterior body of the present invention includes a plurality of support columns and a bottom structure that supports a lower portion of the support columns, and is opened at the lower end portion of the support column of another pallet at the upper end portion of the support column when stacked. around and the upper surface of the constructed pallet to the support abut stacked in a bag-like package member surrounding the, a peripheral wall for outside towards whether we encirclement a plurality of struts, the peripheral wall A lid body integrally provided at the top of the hole, and forming a hole portion through which the upper end portion of the column is inserted in the lid body, and attaching a sealing material to a peripheral edge portion of the hole portion, The sealing material is provided in contact with the support in a state where the support is inserted into the part .

According to the exterior body of the present invention, the upper end portion of the support column protrudes from the upper surface of the lid body and is exposed to the outside. Thereby, the upper end part of a support | pillar can be visually recognized in the state which attached the surrounding wall and the cover body to the pallet. In addition, since the lid is not sandwiched between the upper end of one pallet post and the lower end of another pallet post stacked on this pallet, the post is caused by vibration during transportation. Even if friction is generated at the end of the cover, no crack is generated in the lid, and damage can be prevented .

Since the outer body of the present invention can visually recognize the upper end portion of the support column with the peripheral wall and the lid mounted on the pallet, the position of the upper end portion of the support column can be confirmed, and the pallet can be easily stacked. Can be done. In addition, even if friction occurs at the end of the column due to vibration during transportation, damage from this part does not occur, so it is possible to achieve waterproofing and dustproofing in the pallet for a long time , Can exhibit stable function .

When a bag shape having a peripheral wall and an upper surface, it is assumed easily attached to the pallet, shorten the installation time, it is possible to reduce the material cost.

  If a gap is prevented from being formed between the support column and the lid, the inside of the pallet is sealed, and the waterproof and dustproof effects can be further improved.

Below with reference to reference examples of the exterior body in Figures 1 to 9 will be described.

As shown in FIG. 1, the exterior body of the first reference example is intended to waterproof and dustproof a product (not shown) accommodated in the pallet 1. The exterior body includes a peripheral wall 10 that surrounds and surrounds the plurality of support columns 4 and a lid body 11 that covers an upper opening of the peripheral wall 10.

  As shown in FIG. 2, the pallet 1 uses a so-called post pallet having a rectangular bottom structure 3 and a column 4 erected from a corner portion of the bottom structure 3. The bottom structure 3 includes four frame bodies 7 that connect the lower portions of the four support columns 4 and a connecting rod 8 that connects intermediate portions of the pair of facing frame bodies 7 and 7. The lower part of the column 4 is a leg 9 below the bottom structure 3. A support 6 that opens downward is provided at the lower end of each leg 9. The support 6 is formed of a tapered surface that inclines outward from the lower end edge of the leg 9.

The peripheral wall 10 winds and surrounds the plurality of support columns 4 from the outside. The peripheral wall 10 is composed of a single sheet body 14 having flexibility. As shown in FIG. 3, a cylindrical portion 12 is provided at one end portion 14 c in the longitudinal direction of the sheet body 14, which is formed by folding back to the back surface 14 b side and sewing the edge portion, for example. Thereby, any column 4 is externally fitted to the cylindrical portion 12, and the column 4 and the sheet body 14 can be fixed. Further, a connecting means 25 is provided on the other end portion 14 d in the longitudinal direction of the sheet body 14 and the cylindrical portion 12 on the one end side in the longitudinal direction of the sheet body 14. In this reference example , the connecting means 25 is constituted by the hook-and-loop fastener 13. The hook-and-loop fastener 13 can be attached by pressing the first member 13a on the side raised in a hook shape and the second member 13b on the side raised in a loop shape, and can be attached and detached freely. It can be made. For this reason, in a state where the sheet body 14 is wound around the column 4, the second member 13b can be pressed and adhered to the first member 13a, and the other end portion 14d in the longitudinal direction of the sheet body 14 and the sheet body 14 The cylindrical portion 12 of the longitudinal end portion 14 c is connected via the surface fastener 13.

  As shown in FIG. 1, the lid body 11 covers the upper opening of the peripheral wall 10, and is fitted on the upper end of the peripheral wall 10. That is, the lid body 11 has a rectangular upper surface portion 15 that covers the upper opening of the peripheral wall 10, and a side surface portion 16 that extends downward from the four sides of the upper surface portion 15. The four corner portions of the upper surface portion 15 are each provided with a hole portion 17 through which the support column 4 passes. Thereby, the support | pillar 4 penetrates the hole part 17, and the upper end part 5 of the support | pillar 4 protrudes from the upper surface of the cover body 11, and is exposed outside.

  A sealing material 18 is attached to the peripheral edge of the hole 17. The sealing material 18 includes, for example, nitrile rubber (NBR), fluorine rubber (FKM), urethane rubber (U), silicone rubber (VMQ), ethylene propylene rubber (EPDM), hydrogenated nitrile rubber (HNBR), chloroprene rubber (CR ), Acrylic rubber (ACM), butyl rubber (IIR), chlorosulfonated polyethylene (CSM), epichlorohydrin rubber (CO, ECO), natural rubber (NR), etc., depending on the usage environment, various rubbers and thermoplastic elastomers are used. It is done. Thereby, it is possible to prevent the sealing material 18 from coming into close contact with the support column 4 to form a gap between the support column 4 and the lid body 11.

  Next, a method for mounting the exterior body on the post pallet and a method for stacking the post pallets mounted with the exterior body will be described. First, a product (not shown) is placed on the bottom structure 3 of the post pallet 1. Then, as shown in FIG. 4, the cylindrical body 12 is fitted on one of the columns 4 so that the cylindrical body 12 is positioned inside the post pallet 1. And the sheet | seat body 14 is wound along each support | pillar 4 by making the surface 14a of the sheet | seat body 14 outside. Thereafter, the second member 13b provided on the back surface 14b of the other end portion 14d in the longitudinal direction of the sheet body 14 is superposed on the first member 13a on the surface 14a of the one end portion 14c in the longitudinal direction of the sheet body 14, thereby 14 is connected to one longitudinal end 14c and the other longitudinal end 14d. Thereby, the surrounding wall 10 is formed.

  Next, the lid 11 is mounted on the post pallet 1 and the upper opening of the peripheral wall 10 is covered. That is, as shown by the arrow in FIG. 5, the upper end portion 5 of the support column 4 is passed through the hole portion 17 provided in the lid body 11, and the upper opening portion of the peripheral wall 10 is covered with the lid body 11. As a result, the peripheral wall 10 and the lid 11 are attached to the post pallet 1.

When stacking the post pallets 1 to which the exterior body of the reference example is mounted, another post pallet 1b is loaded on the one post pallet 1a. That is, as shown in FIG. 6, the lower end of each leg 9b of the other post pallet 1b (upper post pallet) is connected to the upper end 5a of each post 4a of one post pallet 1a (lower post pallet). (Support 6b) is brought into contact. As a result, as shown in FIG. 7, another post pallet 1 b can be easily stacked on one post pallet 1 a with the exterior body mounted on the post pallet 1.

Thus, the exterior body of the reference example projects the upper end portion 5 of the support column 4 from the upper surface of the lid 11 and exposes the upper end portion 5 of the support column 4 to the outside. Thereby, in the state which attached the peripheral wall 10 and the cover body 11 to the post pallet 1, since the upper end part 5 of the support | pillar 4 can be visually recognized, the position of the support | pillar 4 can be confirmed and stacking of the post pallet 1 can be carried out. It can be done easily. Moreover, the lid 11 is not sandwiched between the upper end 5a of the post 4a of the post pallet 1a and the lower end of the leg 9b of another post pallet 1b stacked on the post pallet 1a. Even if friction is generated at the ends of the columns 4a and 4b due to the vibration in the inside, damage from this portion does not occur. Thereby, waterproofing and dustproofing in the post pallet 1 can be achieved over a long period of time, and a stable function can be exhibited.

  If one sheet body 14 is wound from the outside of the support 4 of the post pallet 1 to form the peripheral wall 10, the assembly becomes easy, the assembly time is shortened, and the workability of the assembly work is improved. Can do.

  When the cylindrical portion 12 is provided at the one end portion 14c of the sheet body 14, it is not necessary to provide a member for fixing the support column 4 and the peripheral wall 10, and the cost can be reduced. Further, when the connecting means 25 for connecting the other end portion 14 d of the sheet body 14 and the cylindrical portion 12 on the one end portion side of the sheet body 14 is provided, the peripheral wall 10 can be easily fixed along the column 4 of the post pallet 1. can do.

  The lid body 11 has a hole portion 17 through which the upper end portion 5 of the support column 4 is inserted. When a sealing material 18 is attached to the peripheral portion of the hole portion 17, a gap is formed between the support column 4 and the cover body 11. It can be prevented from forming. Thereby, the inside is sealed and the inside of the post pallet can be prevented from being exposed to the outside, and the waterproof and dustproof effects can be further improved.

Next, FIG. 8 shows a second reference example . In this case, the peripheral wall 10 can be constituted by a plurality of flexible sheet bodies (two sheets in the illustrated example) 23 and 24. In other words, the cylindrical portion 31 of one sheet body 23 is externally fitted to the column 4a and surrounds the post pallet 1 along the columns 4a, 4b, and 4c. Moreover, the cylinder part 32 of the other sheet | seat body 24 is externally fitted by the support | pillar 4c, and surrounds the post | mailbox pallet 1 along support | pillar 4c, 4d, 4a. The second member 30b provided at the other longitudinal end portion 23d of one sheet body 23 is connected to the first member 33a provided at the one longitudinal end portion 24c of the other sheet body 24. Further, the first member 30a provided at one longitudinal end portion 23c of one sheet body 23 and the second member 33b provided at the other longitudinal end portion 24d of the other sheet body 24 are connected. Thus, the peripheral wall 10 is configured by the two sheet bodies 23 and 24. Here, the first members 30a and 33a are the first members (sides raised in a hook shape) of the hook and loop fastener constituting the connecting means 25, and the second members 30b and 33b are the faces constituting the connecting means 25. This is the second member of the fastener (the side raised in a loop shape).

Next, a method for mounting the exterior body of the second reference example on the post pallet will be described. First, the cylindrical portion 31 of one sheet body 23 is externally fitted to the column 4a, and the cylindrical portion 32 of the other sheet body 24 is externally fitted to the column 4c positioned diagonally with respect to the column 4a. Then, the one sheet body 23 is wound along the column 4 b, and the second member 30 b of the other longitudinal end portion 23 d of the one sheet body 23 is replaced with the second end portion 24 c of the other sheet body 24 in the longitudinal direction. The first member 33a is overlaid. As a result, the other end 23d in the longitudinal direction of one sheet body 23 and the one end 24c in the longitudinal direction of the other sheet body 24 are connected. Further, the other sheet member 24 is wound along the support column 4d so that the second member 33b of the other end 24d in the longitudinal direction of the other sheet member 24 is replaced with the first end 23c in the longitudinal direction of the one sheet member 23. Superimpose on the member 30a. Thereby, the other longitudinal end 24d of the other sheet member 24 and the one longitudinal end 23c of one sheet member 23 are connected. In this way, the peripheral wall 10 is formed.

Thereafter, the lid 11 is attached in the same manner as in the first reference example . Thereby, the upper end part 5 of the support | pillar 4 protrudes from the upper surface of the cover body 11, and the upper end part 5 of the support | pillar 4 can be exposed outside. Also, when stacking the post pallets 1 to which the exterior body is mounted, the same method as in the first reference example can be used.

For this reason, in the exterior body of the second reference example , in addition to the effect of the exterior body of the first reference example, a plurality of fixing positions of the post pallet 1 and the sheet body 14 can be provided. The attachment state with the body 14 is stabilized. Further, if it is attempted to surround the entire outer periphery of the post pallet 1 with a single sheet member 14, the sheet member 14 becomes larger (longer), increases in weight, becomes bulky, and has a problem in handling. is there. On the other hand, if a peripheral wall is comprised with the some sheet | seat bodies 23 and 24, the sheet | seat body 23 and 24 of one sheet will be lightweight, and also it will become small, and it will become the thing excellent in handling property. In addition, about the structure similar to the exterior body shown in FIGS. 1-7 in the exterior body shown in FIG. 8, the same code | symbol as FIGS. 1-7 is attached | subjected, and the description is abbreviate | omitted.

As another reference example, as shown in FIG. 9, the entire lid 11 can be formed of an elastic body. The upper surface portion 15 and the side surface portion 16 of the lid body 11 can constitute the lid body 11 with a urethane sheet having a thickness of 0.5 mm to 1 mm, for example. A hole 17 is provided in a corner portion of the upper surface portion 15 of the lid body 11. In this case, the sealing material 18 can be omitted because the peripheral edge of the hole 17 is in close contact with the support column 4, and the cost can be reduced. Further, the lid body 11 can follow vibrations during transportation and the like, can further prevent damage, and can exhibit a stable function over a longer period of time.

Hereinafter, the exterior body according to the present invention will be described.
The exterior body according to the present invention, constitute a peripheral wall 10 and the lid 11 in the above reference example formed of a continuous molded body. That is, in the reference example, but the peripheral wall 10 and the lid 11 were those that separates, in the present invention, that has a bag shape having a peripheral wall and an upper surface of the post pallet 1. Thereby, the exterior body of the present invention becomes easy to attach to the post pallet 1, and it is possible to improve the attachment property, shorten the attachment time, and reduce the material cost.

  As a method of attaching the sealing material 18 to the upper surface portion 15 constituting the lid body 11, a frame body 29 as shown in FIGS. 10A and 10B is formed, and then disposed at the corner portion of the upper surface portion 15.
