Description

  The present invention provides a deck board disposed opposite to each other, a plurality of girders for connecting the deck boards, a reinforcing rib extending along an inward surface of the deck board, and the deck board. The present invention relates to a synthetic resin pallet including an insertion hole that is opened in a side surface portion and extends between adjacent girder portions.

  Conventionally, a two-way pallet or a four-way pallet is used as a synthetic resin pallet used when transporting and storing various articles. As these synthetic resin pallets, for example, those disclosed in Patent Documents 1 to 3 are known.

  This kind of synthetic resin pallet is formed in a flat and substantially rectangular parallelepiped shape, and is roughly composed of two deck boards arranged opposite to each other in parallel vertically and a plurality of girders connecting these deck boards. Yes. Further, each side surface portion is formed in a region of four sides between these deck boards. Further, the gap between adjacent beam portions is an insertion hole for inserting a fork of a forklift or a pallet truck, and the insertion hole is formed so as to penetrate the opposing side surface portions. A plurality of reinforcing ribs extending so as to intersect vertically and horizontally are formed on the inward surface of the deck board.

  Such a synthetic resin pallet has many excellent properties such as impact resistance, durability, and moldability, but on the other hand, it may be difficult to slip. Therefore, a sheet-like anti-slip member made of a polymer material called an anti-slip tape is usually attached to the article mounting surface (hereinafter referred to as “mounting surface”) of the deck board. As a material of such an anti-slip tape, an ethylene-vinyl acetate copolymer resin tape (for example, one described in Patent Document 4), or an ethylene / α-olefin copolymer using a metallocene catalyst, Examples thereof include resin tapes (for example, those described in Patent Document 5) that are composed of a polypropylene resin and a compatibilizer. Moreover, about the hardness, generally 90-96 (Shore A hardness) grade is considered preferable. Such an anti-slip tape is inserted and welded into a linear groove provided on the mounting surface in order to maintain sticking durability. The welded anti-slip tape protrudes upward from the mounting surface and comes into contact with the bottom of an article to be loaded or another pallet so that the anti-slip effect is exhibited.

  In the synthetic resin pallets of Patent Documents 1 and 2, the anti-slip tape is arranged so as to overlap with the reinforcing rib formed along the extending direction of the insertion hole of the fork in plan view. When the article is placed on the non-slip tape protruding from the mounting surface, the anti-slip tape portion of the deck board is prevented from being deformed by the weight of the article.

On the other hand, in the paper manufacturing industry, there are cases where pallets are stacked as many as about 30 in the automated production line. Therefore, the pallets used are required to have a certain degree of slip resistance so as not to collapse. Conventionally, wooden pallets have been the mainstream in the paper industry. While such wooden pallets have excellent anti-slip properties when stacked, they cannot be said to have sufficient durability, and they can be out of shape at an early stage or produce wood chips during transportation, affecting the machines in the production line. There was a thing.
Therefore, in recent years, it has been proposed to use a synthetic resin pallet provided with the above-described anti-slip tape excellent in durability and economy in the paper industry.
Japanese Patent Laid-Open No. 11-100035 Japanese Patent No. 2704202 Japanese Utility Model Publication No. 64-14626 Japanese Patent No. 2980159 JP 2001-315778 A

  By the way, in the paper manufacturing industry, a paper product placed on one pallet has a weight of, for example, 800 kg. When using a synthetic resin pallet as disclosed in Patent Documents 1 and 2, the pallet can have sufficient rigidity and anti-slip properties, but is placed on the mounting surface of the synthetic resin pallet. A problem arises that an indentation is formed on the bottom surface of the paper product along the shape of the anti-slip tape due to the weight of the paper product itself.

 That is, the anti-slip tape is formed so as to protrude upward from the mounting surface of the deck board, and the strength is sufficiently secured by the reinforcing rib, so that when the paper product is placed, the bottom surface is pushed upward. In this way, it will be supported. Therefore, the inconvenience that an indentation is formed on the bottom surface by the non-slip tape occurs. Dozens of paper products laminated in the vicinity of the bottom surface where the indentations remain are discarded as they cannot be shipped as products, and the cost for that is wasted.

 The present invention has been made in view of the above-described problems, and provides a synthetic resin pallet that does not form an indentation on the bottom surface of an article to be placed and can be stably laminated with excellent slip resistance. With the goal.

 In order to achieve the above object, the present invention proposes the following means. That is, the present invention provides a deck board disposed opposite to each other, a plurality of girders for connecting the deck boards, a reinforcing rib extending along an inward surface of the deck board, and the deck board. A plastic resin pallet provided with an insertion hole that is formed to extend between the adjacent girder portions that are open to the side surface portion of the deck board, and is provided to project on the article mounting surface of at least one of the deck boards, The anti-slip member is disposed near the center in the width direction of the insertion hole and extends along the extending direction of the insertion hole, and the anti-slip member is detached from the reinforcing rib having the same extending direction. The width direction dimension of the anti-slip member is in a range of 5% to 10% with respect to the width direction dimension of the insertion hole.

  According to the synthetic resin pallet of the present invention, the anti-slip member provided so as to slightly protrude from the article mounting surface (hereinafter referred to as “mounting surface”) of at least one deck board is near the center in the width direction of the insertion hole. And extends along the extending direction of the insertion hole. Moreover, this anti-slip | skid member is arrange | positioned in the position which remove | deviated so that it may not mutually overlap a position on the reinforcement rib which has the same extension direction. Therefore, when an article such as a paper product having a relatively large weight is placed on the mounting surface of the deck board, the upper surface portion where the anti-slip member protrudes is pressed against the bottom surface of the article, and the anti-slip member of the deck board is arranged. The portion to be installed is easily bent downward due to elasticity.

That is, as in the prior art, the upper surface of the anti-slip member is not supported by firmly pushing up the bottom surface of the article to be placed, but is pushed down by the weight of the article and its own elasticity, thereby preventing the slip. Since it moves downward so as to be substantially horizontal with the mounting surface of the portion corresponding to the upper portion of the deck portion of the deck board slightly spaced from the member, formation of indentations on the bottom surface of the article is prevented.
Further, since the article is supported together with the mounting surface of the deck board in this way, a local load is not easily applied to the anti-slip member, and thus the anti-slip member is prevented from being peeled off or damaged, and durability is improved.

  In addition, since the dimension in the width direction of the anti-slip member extending along the insertion hole is in the range of 5% to 10% with respect to the dimension in the width direction of the insertion hole, the anti-slip effect of the anti-slip member is sufficient. Indentation at both ends in the width direction of the anti-slip member is prevented.

  That is, when the dimension in the width direction of the anti-slip member is less than 5% of the dimension in the width direction of the insertion hole, the anti-slip effect of the anti-slip member cannot be sufficiently obtained, and when the dimension exceeds 10%. Since the end portions on both sides in the width direction of the anti-slip member that is pushed by the article to be placed and curves in a substantially concave cross section are protruded upward, there is a risk of forming an indentation on the bottom surface of the article. The above-mentioned range is preferable.

 Further, when the article is not mounted on the synthetic resin pallet, the mounting surface of the deck board is substantially flat, and the anti-slip member protrudes upward from the mounting surface. Therefore, for example, even in the case where a plurality of these synthetic resin pallets are automatically stacked on the production line, the synthetic resin pallets adjacent in the vertical direction are stabilized by the non-slip members, and slipped or collapsed. It can be accurately stacked without any problems.

 According to the synthetic resin pallet of the present invention, the anti-slip member is disposed on the article mounting surface of the deck board, and the deck board is elastically deformed and bent near the portion where the anti-slip member is disposed. It is formed to be easy. Then, when the article is placed on the article mounting surface of the deck board, the portion where the anti-slip member is disposed is bent by the weight of the article, so that an indentation is formed on the bottom surface of the article by the anti-slip member. There is no such thing. In addition, since the anti-slip property of the article mounting surface is sufficiently ensured by the anti-slip member, even when a plurality of synthetic resin pallets are stacked, they do not slide or collapse, and are excellent in stability.

The synthetic resin pallet according to the present invention is a two-way insertion type synthetic resin pallet including a pair of insertion holes extending in parallel with each other.
According to the present invention, a pair of insertion holes extending in parallel with each other is provided, and no other pair of insertion holes is provided, so that a so-called two-way synthetic resin pallet is formed. Has been. These insertion holes pass through the two opposing side surface portions between the deck boards, and are adjacent to each other at both ends in the width direction perpendicular to the extending direction over substantially the entire length in the extending direction. It is formed so as to be sandwiched between girders. Therefore, the insertion hole is formed to have a strength (load resistance) with respect to weight substantially uniformly over substantially the entire length in the extending direction.

  The synthetic resin pallet of the present invention is not limited to the above-described two-way insertion method, and may be a four-way insertion type synthetic resin pallet in which two pairs of insertion holes are arranged orthogonal to each other.

Hereinafter, a synthetic resin pallet according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 4 is a schematic partial front view showing the vicinity of the anti-slip tape of the synthetic resin pallet in an enlarged manner, FIG. 4 is a schematic partial cross-sectional view showing a substantially quarter of the AA cross section of FIG. 2, and FIG. FIG. 6 is a schematic front view showing a state in which an article is placed on the synthetic resin pallet according to FIG. 6, and FIG. 6 is an enlarged view of the vicinity of the non-slip tape in a state in which the article is placed on the synthetic resin pallet according to this embodiment. It is a schematic fragmentary sectional view shown.

The synthetic resin pallet 1 of this embodiment is formed by injection molding or the like using a material mainly composed of a thermoplastic resin such as a polyolefin resin such as polyethylene, polypropylene or ethylene-propylene copolymer, or polystyrene. . Further, the synthetic resin pallet 1 formed in this way has a certain degree of elasticity. For example, when polypropylene is used, the flexural modulus is 0.8 × 10 ⁴ kg / cm to 1.5. × is a ¹⁰ 4 kg / cm, in the case of using the high-density polyethylene, its flexural modulus is a ^{0.4 × 10 4 kg / cm~1.1 ×} 10 4 kg / cm.

 As shown in FIGS. 1 and 2, the synthetic resin pallet 1 according to this embodiment includes two substantially rectangular plate-like deck boards 2 arranged opposite to each other, and three substantially columnar girders that connect these deck boards 2. It has a portion 3 and is formed in a substantially rectangular parallelepiped shape that is flat as a whole. Furthermore, the deck board 2 is made into the upper surface deck board 2a and the lower surface deck board 2b by the arrangement.

 The girder 3 is formed so as to extend in a direction orthogonal to the longitudinal direction of these deck boards 2 (hereinafter abbreviated as “short direction”) and is arranged in parallel with each other. Further, two spaces extending in the lateral direction are formed so as to be sandwiched between the beam portions 3, and these are formed as a pair of insertion holes 4. As shown in FIG. 2, these insertion holes 4 are substantially rectangular holes whose cross-sectional shape perpendicular to the extending direction is flat, and the dimension D1 of the deck board 2 in the longitudinal direction is the insertion hole 4. It is the dimension of the width direction.

 In addition, side portions 5 are formed in the four sides between the opposing deck boards 2. Further, the side surface portions 5 at both ends in the short direction of the deck board 2 are provided with openings 5a so as to be arranged between the girder portions 3, and the openings 5a of the side surface portions 5 facing each other are provided. The insertion hole 4 is formed so as to penetrate. Fork of a forklift or a pallet truck is inserted into these insertion holes 4 when the synthetic resin pallet 1 is conveyed.

 In addition, two concave grooves 6 extending in the short direction are provided on a surface (article mounting surface) facing outward of the top deck board 2a, and these grooves 6 are mutually connected in the longitudinal direction of the deck board 2a. They are spaced apart in parallel. Further, as shown in FIG. 2, these grooves 6 are respectively disposed near the center of the insertion hole 4 in the width direction. Moreover, the dimension of the width direction of the groove | channel 6 shown by S1 in FIG. 3 is set to S1 = 22 mm, for example. The depth dimension S2 orthogonal to the width direction of the groove 6 is, for example, S2 = 0.5 mm. Further, an anti-slip tape (anti-slip member) 7 slightly narrower than the dimension S1 in the width direction of the groove 6 is disposed along the groove 6 so as to be inserted into the grooves 6. Yes.

 These non-slip tapes 7 extend in the short direction of the top deck board 2a and are welded and fixed to the bottom surface portion in the groove 6. As this non-slip tape 7, for example, a known sheet-like anti-slip material having soft elasticity such as low density polyethylene, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, thermoplastic rubber or the like is used. Can do.

 The dimension D2 in the width direction of the anti-slip tape 7 is set in the range of 5% to 10% with respect to the dimension D1 in the width direction of the insertion hole 4. Specifically, for example, the width direction dimension D1 of the insertion hole 4 is 260 mm, and the width direction dimension D2 of the anti-slip tape 7 is 20 mm. The thickness dimension T1 orthogonal to the width direction of the anti-slip tape 7 is, for example, T1 = 1.0 mm. Further, a dimension T2 at which the anti-slip tape 7 protrudes upward from the mounting surface of the upper deck board 2a is, for example, T2 = 0.5 mm.

 Further, both end corners in the width direction of the upper surface of the anti-slip tape 7 are end portions 7a. In the present embodiment, the end portion 7a is formed in a substantially right-angle cross section, but the end portion 7a has a substantially cross-sectional shape in order to more reliably prevent indentation on an article placed on the upper surface of the anti-slip tape 7. You may form in R shape and cross-sectional substantially C shape.

 Further, as shown in FIG. 4, reinforcing ribs 8 that intersect vertically and horizontally between adjacent beam portions 3 are disposed in the insertion holes 4 on the inward surface of the upper deck board 2 a. The reinforcing rib 8 has a substantially plate shape that protrudes inwardly from the upper deck board 2a, and more specifically, the reinforcing rib 8a extends in the longitudinal direction of the upper deck board 2a (left and right in FIG. 4). And reinforcing ribs 8b extending in the short direction (vertical direction in FIG. 4), and edge reinforcing ribs 8c provided in the vicinity of the opening 5a.

 A plurality of reinforcing ribs 8a are provided so as to connect the adjacent beam portions 3 to each other, and the reinforcing ribs 8a are arranged relatively densely. The reinforcing ribs 8b are formed in two strips so as to extend in parallel to the extending direction of the insertion hole 4 and to divide the adjacent beam portions 3 into three equal parts. Further, a plurality of edge reinforcing ribs 8c are arranged in parallel with the extending direction of the reinforcing ribs 8b so as to reinforce the opening 5a of the insertion hole 4, so that the openings 5a of the insertion holes 4 are arranged in the opening 5a. It is possible to increase the strength against the impact received when the tip of the fork is inserted.

Further, the reinforcing rib 8b and the anti-slip tape 7 were removed so as not to overlap each other when viewed from a direction orthogonal to the mounting surface of the top deck board 2a (hereinafter abbreviated as "plan view"). Placed in position. Further, the reinforcing rib 8c and the anti-slip tape 7 are also arranged at positions that are not overlapped with each other in plan view.
Further, a portion indicated by reference numeral 9 where the reinforcing rib 8a and the reinforcing rib 8b intersect is a through hole, and a grommet 10 for preventing the slip of the fork is inserted into the through hole 9.

Next, the operation when the paper product (article) P is placed on the synthetic resin pallet 1 of this embodiment will be described.
When a paper product P having a weight of about 800 kg is mounted on the synthetic resin pallet 1 of this embodiment, for example, by stacking a plurality of sheets and packing them with wrapping paper, as shown in FIGS. The portions corresponding to the upper portions of the upper deck boards 2a above the beam portions 3 support the paper product P firmly and hardly deform, but the portions corresponding to the upper portions of the respective insertion holes 4 of the upper surface deck board 2a are The paper product P is slightly bent downward due to the weight of the paper product P.

 That is, the upper surface portion of the non-slip tape 7 protruding slightly upward from the mounting surface of the upper surface deck board 2a is in contact with the bottom surface PB of the paper product P, and is pressed downward by the weight of the paper product P. The portion of the deck board 2a near the anti-slip tape 7 bends downward so as to form a valley portion of the recess. In this embodiment, the amount of bending is, for example, about 0.5 mm at the maximum.

 At this time, bending stress is generated in the upper deck board 2a, so that it resists the weight of the paper product P and tries to return to the original state. Therefore, the non-slip tape 7 is brought into close contact with the bottom surface PB of the paper product P, and a static frictional force works. The static friction coefficient of the anti-slip tape 7 is set to be larger than 0.5, for example, and exhibits a sufficient anti-slip property.

 As described above, according to the synthetic resin pallet 1 according to the present embodiment, the antiskid tape 7 extending along the extending direction of the insertion hole 4 is provided on the mounting surface of the upper deck board 2a. Since the non-slip tape 7 is disposed in the vicinity of the center of the insertion hole 4 in the width direction, when the relatively heavy paper product P is placed on the mounting surface, the non-slip tape 7 is placed on the bottom surface PB of the paper product P. The portion of the top deck board 2a where the anti-slip tape 7 is disposed is easily bent downward due to elasticity.

That is, the upper surface of the non-slip tape 7 is pushed down by the weight of the paper product P and its own elasticity without supporting the bottom surface PB of the paper product P to be placed firmly, as in the prior art. Thus, the bottom surface of the paper product P is moved downward so as to be substantially horizontal with the mounting surface of the portion corresponding to the upper portion of the girder portion 3 of the upper deck board 2a slightly spaced from the antiskid tape 7. Formation of indentations in PB is prevented.
Further, since the paper product P is supported together with the mounting surface of the upper deck board 2a in this way, it is difficult to apply a local load to the anti-slip tape 7, and thus the anti-slip tape 7 is prevented from being peeled off or damaged, and thus durable. Improves.

  Further, since the anti-slip tape 7 is disposed at a position separated from the reinforcing rib 8b and the reinforcing rib 8c that have the same extending direction in plan view so as not to overlap each other, the top deck board 2a When the paper product P is placed on the mounting surface, the portion of the top deck board 2a where the anti-slip tape 7 is disposed is easily bent downward by elasticity. Therefore, indentations on the bottom surface PB of the paper product P can be reliably prevented.

 Further, since the dimension D2 in the width direction of the anti-slip tape 7 extending along the insertion hole 4 is set in the range of 5% to 10% with respect to the dimension D1 in the width direction of the insertion hole 4, the anti-slip The anti-slip effect of the tape 7 can be sufficiently secured, and the indentation on the paper product P at the end portion 7a of the anti-slip tape 7 can be satisfactorily prevented.

 Here, when the dimension D2 in the width direction of the anti-slip tape 7 is set to be less than 5% of the dimension D1 in the width direction of the insertion hole 4, the anti-slip effect of the anti-slip tape 7 can be sufficiently obtained. In addition, when it is set to exceed 10%, both side end portions 7a of the anti-slip tape 7 which is pushed and curved protrudes upward, and an indentation is formed on the paper product P to be placed. Therefore, the above range is preferable.

Further, when an article such as paper product P is not mounted on the synthetic resin pallet 1 of the present embodiment, the upper deck board 2a has an original substantially flat shape, and the non-slip tape 7 is formed from the mounting surface. Is slightly protruding upward. Therefore, for example, even when a plurality of these synthetic resin pallets 1 are automatically stacked in the production line, the synthetic resin pallets 1 adjacent to each other in the vertical direction are stabilized by the non-slip tape 7 so as to slide down or load. Accurately stack without collapsing.
In addition, using a wooden pallet as in the past, it is excellent in durability and economy, without losing its shape at an early stage or causing wood chips etc. during transportation to affect the machinery in the production line. .

In addition, this invention is not limited to the said Example, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, in the present embodiment, the description has been given on the assumption that the anti-slip tape 7 is disposed only on the mounting surface of the upper deck board 2a. However, the present invention is not limited to this, and the anti-slip tape 7 is also disposed on the outer surface facing the lower deck board 2b. It does not matter if it is installed.

  In the present embodiment, the non-slip tape 7 has been described as being inserted and welded into the groove 6 of the upper deck board 2a. However, the anti-slip tape 7 is not limited to this as long as it can exhibit a sufficient anti-slip property. Alternatively, for example, a configuration in which the anti-slip tape 7 is directly welded on the flat mounting surface of the upper deck board 2a may be employed.

  In this embodiment, the thickness dimension T1 of the anti-slip tape 7 is set to 1.0 mm, and the dimension T2 of the anti-slip tape 7 protruding upward from the mounting surface of the upper deck board 2a is described as 0.5 mm. However, it is not limited to this. That is, the dimensions can be variously set according to the weight of the article to be mounted and the outer shape of the synthetic resin pallet 1. For example, T1 = 1.5 mm, T2 = 1.0 mm, or other dimensions. You may set it to.

  In this embodiment, the paper product P is mounted on the synthetic resin pallet 1. However, the present invention is not limited to this. That is, the article to be mounted on the synthetic resin pallet 1 may be other than a paper product as long as it should prevent the formation of indentation, and can support mounting of a wide variety of articles.

  Hereinafter, the present invention will be described in more detail using specific examples. However, the present invention is not limited to this embodiment.
