Japanese Patent Application Publication No. 2014-162557

By the way, for example, as pillars, there are corner pillars provided at the four corners of the pallet, intermediate pillars provided in the middle of a pair of corner pillars lined up along each side of the pallet, and pillars provided at the center of the pallet. In a configuration (a four-way pallet) in which a central pillar is provided, there is no pillar that extends over the entire predetermined width direction of the pallet, and even if a reinforcing member is embedded in the pillar, There is a concern that the effect of suppressing deformation of the pallet etc. will be hardly achieved.

Furthermore, a structure is desired that suppresses deformation of the pallet when it is lifted by a forklift.

The present invention has been made to solve the above-mentioned problems, and its purpose is to provide a pallet that can be effectively reinforced with reinforcing members.

Below, each means suitable for solving the above objectives will be explained in terms of sections. Note that effects specific to the corresponding means will be added as necessary.

Means 1. a deck portion having a generally rectangular shape in plan view and having a placement surface on which an article can be placed;
and a plurality of pillar parts protruding downward from the deck part ,
In a pallet configured by welding together a lower component including the pillar part and a lower part of the deck part, and an upper component part including the upper part of the deck part,
The pillar portions are located between corner pillar portions provided at four corners of the deck portion and a pair of corner pillar portions arranged along a pair of opposing first side portions of the side portions of the deck portion. A first intermediate column provided at a position and a pair of opposing second side portions extending substantially perpendicularly to the first side portion among the side portions of the deck portion are arranged respectively. a second intermediate pillar part provided at an intermediate position between the pair of corner pillar parts, and a central pillar part provided at a central part of the deck part,
A fork insertion part into which a fork of a transportation means including a fork can be inserted between the corner post and the first intermediate post and between the corner post and the second intermediate post. established,
A reinforcing member is installed from the upper part of each of the first intermediate pillar parts to the upper part of each of the second intermediate pillar parts,
comprising a sealed housing part in which the reinforcing member is housed;
The accommodating part includes a lower accommodating recess provided on the upper surface side of the lower component part and accommodating the lower part of the reinforcing member, and an upper accommodating part provided on the lower surface side of the upper component part accommodating the upper part of the reinforcing member. A pallet comprising a recess .

According to means 1, the upper part of each first intermediate pillar part provided at an intermediate position of each first side part of the deck part, and each second intermediate pillar part provided at an intermediate position of each second side part of the deck part. A reinforcing member is provided across the top of the pillar part, and the reinforcing member is arranged in a generally square frame shape as a whole, so that the strength and rigidity of the pallet, especially the deck part between the pillar parts, can be effectively increased. . Therefore, for example, in the case where a pallet is installed on a pair of opposing rails provided parallel to each other and spaced apart from each other, corner posts provided along a pair of first side portions of the pallet, Further, even in a situation where the first intermediate column part is supported by the rail, but the second intermediate column part and the central column part therebetween are not supported, deformation of the pallet etc. can be reliably suppressed.

Further, two reinforcing members are each placed above the pair of fork insertion portions provided on the first side of the pallet, and two reinforcing members are provided on the second side of the pallet. Two reinforcing members are each stretched over the pair of fork insertion portions. Therefore, even if the fork of the conveying means is inserted into the fork insertion part from either the first side side or the second side side and the pallet is lifted, the lower surface side of the deck part is A reinforcing member extending in a direction intersecting the fork is provided at the portion pressed by the fork. Therefore, deformation of the pallet when the pallet is lifted by the transport means can be more reliably suppressed.

Furthermore, both ends of the reinforcing member are located above the column and are supported by the column. For this reason, for example, compared to the case where the reinforcing member is installed only in the deck part between the pillar parts, it is possible to prevent the peripheral part of the reinforcing member from being unable to withstand the force received from the reinforcing member and becoming deformed. I can do it.

For example, when installing reinforcing members along each side of the pallet between the corner posts, it is possible to install two reinforcing members above each fork insertion part. There is a concern that the total length of the reinforcing member used for one pallet becomes relatively long. In this case, there is a risk that the weight of the pallet will increase (for example, the amount of loaded items will decrease due to weight restrictions) and the manufacturing cost of the pallet will increase. In this regard, according to the present means 1, it is possible to shorten the total length of the reinforcing members used for one pallet as much as possible while extending two reinforcing members above each fork insertion part, and thereby to avoid the above-mentioned concerns. can be suppressed.

Furthermore, for example, when reinforcing members are installed between each corner pillar and the central pillar, one end of all the reinforcing members is supported by the central pillar. Even if it is possible to secure an area that can support the center column, the load tends to concentrate on the center column, causing deformation (if the center column is deformed, for example, the installation of a pallet) There is a concern that this may lead to deterioration of balance, etc. In this regard, according to the present means 1, it is possible to avoid a situation where force is applied from the four reinforcing members to a specific column portion, and the above-mentioned concerns can be dispelled.

Furthermore, for example, two first reinforcing members are provided parallel to each other from the first intermediate pillar part to the second intermediate pillar part, and between the pair of first reinforcing members, from the corner pillar to the center When two second reinforcing members are provided parallel to the pair of first reinforcing members across the column, that is, when all the reinforcing members extend in the same direction, the extension of the reinforcing members Since there is no reinforcing member extending in a direction perpendicular to the direction in which the pallet is located, there is a concern that the pallet may easily deform when bending stress occurs in the same direction. In this regard, according to the present means 1, since two reinforcing members are provided each extending in directions intersecting with each other, the above-mentioned concerns can be eliminated, and deformation of the pallet etc. can be more reliably prevented. be able to.
Further, the reinforcing member embedded in the pallet can be reliably positioned, and wobbling of the reinforcing member can be suppressed. In addition, since the reinforcing member can be installed and held in the desired position during the work process of welding the lower component and the upper component, it is possible to improve work efficiency and, by extension, productivity. .
Furthermore, by providing the housing section not only in one of the lower component part and the upper component part, but also in both, the height of the reinforcing member can be secured and the height of the pallet can be suppressed. (If either the lower accommodation recess or the upper accommodation recess is not provided, the vertical width of the deck part will increase accordingly). Therefore, it is possible to improve transportation and storage efficiency. Furthermore, it is possible to improve durability when stress is applied to the pallet such that the lower component and the upper component are displaced in the horizontal direction.

Means 2. Means 1 characterized in that the reinforcing member accommodated in the accommodating portion is in contact with the bottom surface of the lower accommodating recess at the lower side, and in contact with or close to the bottom surface of the upper accommodating recess at the upper side. Palette as described in.

Means 3. The lower part of the deck part of the lower component includes a plate-shaped lower plate part and a lower deck reinforcing rib extending upward from the upper surface of the lower plate part,
The lower deck reinforcing rib is provided at a portion where the lower plate portion is present and a portion corresponding to the column portion,
The lower accommodation recess includes a first corresponding part provided above the first intermediate pillar part, a second corresponding part provided above the second intermediate pillar part, the first intermediate pillar part and the second corresponding part provided above the second intermediate pillar part. and a fork corresponding part provided between the intermediate pillar part and above the fork insertion part,
In the fork corresponding portion of the lower accommodation recess, the upper surface of the lower plate portion constitutes a bottom surface of the lower accommodation recess,
According to means 1 or 2 , the lower housing recess is provided with a lower wall portion extending substantially parallel to a side surface of the reinforcing member in the fork corresponding portion provided above the fork insertion portion. palette.

Note that the upper plate portion 22 of this embodiment is non-porous. Additionally, the lower deck reinforcing ribs 15, the column reinforcing ribs 18, and the upper deck reinforcing ribs 23 are basically parallel to the first side portion 6 and the second side portion 8 of the deck portion 3. (See Figures 5 and 6).

Now, as shown in FIGS. 3, 7, etc., in this embodiment, a rectangular cylindrical reinforcement made of metal (for example, iron, stainless steel, etc.) is provided between the lower component part 12 and the upper component part 21. A housing portion 32 in which the member 31 is installed (buried) is provided. To explain more specifically, as shown in FIG. 4 and FIG. A lower accommodation recess 33 is provided which extends in a shape and accommodates the lower part of the reinforcing member 31 . Each lower accommodation recess 33 has a first corresponding part 34 provided above the first intermediate pillar part 7 , a second corresponding part 35 provided above the second intermediate pillar part 9 , and a first corresponding part 34 provided above the first intermediate pillar part 7 . , and a fork corresponding portion 36 provided above the fork insertion portion 11 and between the second intermediate column portion 9 and the fork insertion portion 11 . Further, as shown in FIGS. 5, 9, etc., the lower accommodation recess 33 is provided in such a way as to remove the target portion of the lower deck reinforcing rib 15, and the fork corresponding portion 36 of the lower accommodation recess 33 In this case, the upper surface of the lower plate portion 14 constitutes the bottom surface of the lower accommodation recess 33.

Furthermore, as shown in FIGS. 8 and 9, the fork corresponding part 36 connects the ends of the lower deck reinforcing rib 15 that constitute the inner surface of the fork corresponding part 36, and is installed in the lower accommodation recess 33. A lower wall portion 37 is provided that extends substantially parallel to the side surface of the reinforcing member 31. In addition, as shown in FIG. 9, the first corresponding portion 34 includes a lower opposing wall portion 38 that faces substantially parallel to the end portion of the reinforcing member 31 installed in the lower housing recess 33. Further, as shown in FIGS. 5, 8, etc., the widths of the first corresponding portion 34 and the fork corresponding portion 36 are configured to be slightly wider than the longitudinal width of the cross-sectional shape of the reinforcing member 31. On the other hand, as shown in FIG. 5, the width of the second corresponding portion 35 is the same as that of the fork corresponding portion 36 at the portion that is continuous with the fork corresponding portion 36, but the width of the second corresponding portion 35 is the same as that of the fork corresponding portion 36; The portion on the second side portion 8 side that accommodates the fork portion is configured to have a width wider than the width of the fork corresponding portion 36. In addition, the bottom surface of the first corresponding part 34 and the bottom surface of the second corresponding part 35 are at the same height as the bottom surface of the fork corresponding part 36, that is, the top surface of the lower plate part 14 (see FIG. 9). ).

Further, as shown in FIG. 6, an upper accommodation recess 41 for accommodating the upper part of the reinforcing member 31 is provided on the lower surface side of the upper component 21 at a position corresponding to the lower accommodation recess 33. The upper accommodation recess 41 is provided in such a manner that a target portion of the upper deck reinforcing rib 23 is removed, and the lower surface of the upper plate portion 22 constitutes the bottom surface (top wall surface) of the upper accommodation recess 41. Further, unlike the second corresponding portion 35 of the lower accommodation recess 33, the upper accommodation recess 41 does not have a widened portion, and the width is constant at any position in the extending direction. In addition, the upper accommodation recess 41 connects the ends of the upper deck reinforcing ribs 23 that constitute the inner surface of the upper accommodation recess 41 and is approximately parallel to the side surface of the reinforcing member 31 installed in the upper accommodation recess 41. and an upper opposing wall 43 that faces substantially parallel to both ends of the reinforcing member 31 installed in the upper housing recess 41.

When welding the lower component part 12 and the upper component part 21, for example, as shown in FIG. 31, as shown in FIG. 7, the upper component 21 is placed over the lower deck reinforcing rib 15 and the lower edge of the upper deck reinforcing rib 23 are welded together. As a result, the lower component part 12 and the upper component part 21 are integrated to form the pallet 1 of this embodiment, and inside the pallet 1, the lower accommodation recess 33 and the upper accommodation recess 41 A housing portion 32 is formed to house the reinforcing member 31. The reinforcing member 31 accommodated in the accommodating portion 32 is brought into substantially contact with the bottom surface of the upper accommodating recess 41, that is, the lower surface of the upper plate portion 22.

Moreover, as shown in FIG. 5 etc., in this embodiment, the reinforcing member 31 extends from the upper part of one of the pair of first intermediate pillar parts 7 to the upper part of the other first intermediate pillar part 7. In order to make it possible to install the central accommodating portion 44, a recess is formed on the upper surface side of the lower component portion 12 and on the lower surface side of the upper component portion 21. Depending on the required strength of the pallet 1, as shown in FIG. By integrating the and the upper component 21, not only the reinforcing member 31 extending from the upper part of the first intermediate pillar part 7 to the upper part of the second intermediate pillar part 9 but also one of the first intermediate pillar parts A reinforcing member 31 is embedded in the pallet 1 and extends from the upper part of the first intermediate pillar part 7 to the upper part of the other first intermediate pillar part 7 via the upper part of the central pillar part 10.

As described in detail above, according to the present embodiment, the upper part of each first intermediate pillar part 7 provided at an intermediate position of each first side part 6 of deck part 3 and each second side of deck part 3 A reinforcing member 31 is provided over the upper part of each second intermediate pillar part 9 provided at an intermediate position of the side part 8, and the reinforcing member 31, which is arranged in a generally rectangular frame shape as a whole, strengthens the pallet 1, especially the pillar part 4. The strength and rigidity of the deck portion 3 in between can be effectively increased. Therefore, for example, in the case where the pallet 1 is installed on a pair of opposing rails provided parallel to each other and spaced apart from each other, a corner provided along a pair of first side portions 6 of the pallet 1 Even in a situation where the pillar portion 5 and the first intermediate pillar portion 7 are supported by the rail, but the second intermediate pillar portion 9 and the central pillar portion 10 between them are not supported, deformation of the pallet 1 is ensured. can be suppressed.

Furthermore, two reinforcing members 31 are each stretched over the pair of fork insertion portions 11 provided on the first side portion 6 side of the pallet 1, and Two reinforcing members 31 are stretched over the pair of fork insertion portions 11 provided on the 8 sides. Therefore, even if the fork of a forklift or hand lift is inserted into the fork insertion part 11 from either the first side part 6 side or the second side part 8 side of the pallet 1 and the pallet 1 is lifted, A reinforcing member 31 extending in a direction crossing the fork is provided at a portion of the deck portion 3 whose lower surface side is pressed by the fork. Therefore, deformation of the pallet 1 when lifted by a forklift or the like can be more reliably suppressed.

Further, both ends of the reinforcing member 31 are located above the column portions 4 (the first intermediate column portion 7 and the second intermediate column portion 9), and are supported by the column portions 4. For this reason, for example, compared to the case where the reinforcing member 31 is installed only on the deck part 3 between the pillar parts 4, the peripheral part of the reinforcing member 31 cannot withstand the force received from the reinforcing member 31 and becomes deformed. The situation can be prevented.

For example, when installing reinforcing members along each side of the pallet between the corner posts, it is possible to install two reinforcing members above each fork insertion part. There is a concern that the total length of the reinforcing member used for one pallet becomes relatively long. In this case, there is a risk that the weight of the pallet will increase (for example, the amount of loaded items will decrease due to weight restrictions) and the manufacturing cost of the pallet will increase. In this regard, according to the present embodiment, it is possible to extend two reinforcing members 31 above each fork insertion portion 11 and to shorten the overall length of the reinforcing members 31 used for one pallet 1 as much as possible. The above concerns can be suppressed.

Furthermore, for example, when reinforcing members are installed between each corner pillar and the central pillar, one end of all the reinforcing members is supported by the central pillar. Even if it is possible to secure an area that can support the center column, the load tends to concentrate on the center column, causing deformation (if the center column is deformed, for example, the installation of a pallet) There is a concern that this may lead to deterioration of balance, etc. In this regard, according to the present embodiment, it is possible to avoid a situation in which force is applied from the four reinforcing members 31 to a specific column portion 4, and the above-mentioned concerns can be eliminated.

Furthermore, for example, two first reinforcing members are provided parallel to each other from the first intermediate pillar part to the second intermediate pillar part, and between the pair of first reinforcing members, from the corner pillar to the center When two second reinforcing members are provided parallel to the pair of first reinforcing members across the column, that is, when all the reinforcing members extend in the same direction, the extension of the reinforcing members Since there is no reinforcing member extending in a direction perpendicular to the direction in which the pallet is located, there is a concern that the pallet may easily deform when bending stress occurs in the same direction. In this regard, according to the present embodiment, since two reinforcing members 31 are provided that extend in mutually intersecting (orthogonal) directions, the above-mentioned concerns can be eliminated, and the deformation of the pallet 1 can be prevented. This can be prevented more reliably.

In addition, for example, two reinforcing members are arranged in a substantially dogleg shape from one of the second intermediate pillar parts to each of the first intermediate pillar parts, and the central pillar is arranged parallel to the two reinforcing members. When arranging two reinforcing members in a substantially dogleg shape from the corner to the corner pillar, from the first side of one side to the first side of the other, There is a concern that uncorresponding parts will be continuous and the parts will be easily deformed. In this regard, according to the present embodiment, the portion of the deck portion 3 that does not correspond to the pillar portion 4 and the reinforcing member 31 extends from one first side portion 6 to the other first side portion 6. Moreover, since it does not extend from one second side portion 8 to the other second side portion 8, the above-mentioned concerns can be eliminated, and deformation of the pallet 1 can be more reliably prevented. be able to.

The pallet 1 also includes a lower storage recess 33 provided on the upper surface side of the lower component part 12 and accommodating the lower part of the reinforcing member 31, and a lower accommodation recess 33 provided on the lower surface side of the upper component part 21 and accommodating the upper part of the reinforcing member 31. An accommodating portion 32 is provided, which includes an upper accommodating recess 41. Therefore, the reinforcing member 31 embedded in the pallet 1 can be reliably positioned, and wobbling of the reinforcing member 31 can be suppressed. In addition, since the reinforcing member 31 can be installed and held in the desired position during the work process of welding the lower component 12 and the upper component 21, work efficiency is improved, and productivity is improved. be able to. Furthermore, by providing the accommodating portion 32 not only in one of the lower component portion 12 and the upper component portion 21 but also in both, the height of the reinforcing member 31 is ensured and the pallet 1 The height of the deck portion 3 can be suppressed (if either the lower storage recess 33 or the upper storage recess 41 is not provided, the vertical width of the deck portion 3 will increase accordingly) ). Therefore, it is possible to improve transportation and storage efficiency. In addition, it is possible to improve the durability when stress is applied to the pallet 1 such that the lower component 12 and the upper component 21 are displaced in the horizontal direction.

Note that the present invention is not limited to the content described in the above embodiment, and may be implemented as follows, for example. Of course, other applications and modifications not exemplified below are also possible.

Even in this case, the reinforcing member 31 embedded in the pallet 1 can be reliably positioned, and while improving the workability of welding the lower component 12 and the upper component 21, the backlash of the reinforcing member 31 can be prevented. Effects such as suppressing this can be achieved. In addition, it is also possible to omit the central accommodating part 44.

(b) In the above embodiment, the upper constituent part 21 and the lower constituent part 12 are made of polypropylene, but they may be made of other resin materials such as polyethylene, PET, and polyamide. Further, in the above embodiment, the reinforcing member 31 is made of metal and has a rectangular cylindrical shape, but the material and shape of the reinforcing member 31 are not particularly limited. It is sufficient that the strength and rigidity of the pallet 1 can be increased compared to a configuration in which the lower deck reinforcing ribs 15 and the upper deck reinforcing ribs 23 are simply extended. For example, the reinforcing member may be made of glass fiber, carbon fiber, etc., or may have an I-shaped cross section, a cylindrical cross section, a (solid) circular cross section, a (solid) rectangular cross section, etc. may be configured. Furthermore, for example, the reinforcing member may be made of a synthetic resin made of a material with greater strength than the lower component 12 and the like, or a synthetic resin shaped into a shape that increases its strength. In addition, it is also possible to configure the reinforcing member to have a generally doglegged shape or a square annular shape.

(c) In the above embodiment, the degree of the gap between the reinforcing member 31 housed in the housing section 32 and the housing section 32 is not particularly limited, but it is desirable that it be as small as possible. In particular, in the vertical direction (thickness direction of the deck section 3), the reinforcing member 31 accommodated in the accommodation section 32 comes into contact with the bottom surface of the lower accommodation recess 33 (the upper surface of the lower plate section 14), and the upper accommodation recess 41 It is desirable that the contact surface be in contact with or be close to the bottom surface (lower surface of the upper plate portion 22). Furthermore, a lower opposing wall portion 38 may also be provided in the second corresponding portion 35 of the lower housing recess 33.

Further, in the embodiment described above, the accommodating portion 32 is sealed, but it may be configured to be partially opened.
