（実施の形態１）
本発明の実施の形態１に係る発泡パレットについて図１乃至図７を参照して説明する。最初に、図１を参照して、本実施の形態１に係る発泡パレット１の全体構成に関して説明する。図１は、発泡パレット１の組み立て前後の状態を示す図である。発泡パレット１は、物流の現場などにおいてフォークリフトを用いた荷物の管理・運搬に使用されるものであり、パレット本体２及び補強材３を備える。
(Embodiment 1)
A foam pallet according to Embodiment 1 of the present invention will be described with reference to FIGS. First, the overall configuration of the foam pallet 1 according to the first embodiment will be described with reference to FIG. FIG. 1 is a view showing a state before and after assembly of the foam pallet 1. The foam pallet 1 is used for managing and transporting cargo using a forklift at a physical distribution site, and includes a pallet body 2 and a reinforcing material 3.
ここで、パレット本体２は、発泡合成樹脂で成型されている。この発泡合成樹脂は、例えばポリスチレン、ポリエチレン、ポリプロピレンなどのポリオレフィン系樹脂であり、本実施の形態１に係るパレット本体２は例えばＥＰＳ(expanded polystyrene)パネルで成型されている。 Here, the pallet main body 2 is molded with foamed synthetic resin. This foamed synthetic resin is, for example, a polyolefin-based resin such as polystyrene, polyethylene, or polypropylene, and the pallet body 2 according to the first embodiment is molded by, for example, an EPS (expanded polystyrene) panel.
パレット本体２は、図１及び図２に示すように、荷物が積載される積載面２１と、積載面２１の下面に形成される複数（本実施の形態１では３本）の桁体２２と、が一体成形されている。このため、部品点数や製造工数を低減し、コストダウンを図ることができる。 As shown in FIGS. 1 and 2, the pallet body 2 includes a loading surface 21 on which a load is loaded, and a plurality of (three in the first embodiment) girders 22 formed on the lower surface of the loading surface 21. Are integrally molded. For this reason, the number of parts and the number of manufacturing steps can be reduced, and the cost can be reduced.
パレット本体２の積載面２１は、所定の肉厚（例えば４０ｍｍ）を有し、平面視で矩形形状（正方形状）であり、例えば、縦幅１１００ｍｍ×横幅１１００ｍｍ×厚さ４０ｍｍである。なお、パレット本体２の形状は、平面視で多角形状を含む各種の形状から選択可能である。 The loading surface 21 of the pallet body 2 has a predetermined thickness (for example, 40 mm) and has a rectangular shape (square shape) in a plan view, for example, 1100 mm long × 1100 mm wide × 40 mm thick. In addition, the shape of the pallet main body 2 can be selected from various shapes including a polygonal shape in plan view.
パレット本体２の桁体２２は、積載面２１の高さを嵩上げする支持部材であり、その長手方向の長さが積載面２１の一側面と同じ（１１００ｍｍ）である板形状であり、例えば長手幅１１００ｍｍ×短手幅２０７．５ｍｍ×厚み９０ｍｍ（左右側の２本）、又は長手幅１１００ｍｍ×短手幅２８５ｍｍ×厚み９０ｍｍ（中央部）となる。桁体２２は、図１に示すように、フォークリフトのフォークを２方差しとすべく、積載面２１の一側面（右側面又は左側面）と平行で、且つ積載面２１の下面の左右両端側、及びその中央部に、フォークの差し込み方向に沿って、並列されている。 The beam body 22 of the pallet main body 2 is a support member that raises the height of the stacking surface 21 and has a plate shape whose length in the longitudinal direction is the same as that of one side surface of the stacking surface 21 (1100 mm). The width 1100 mm × short width 207.5 mm × thickness 90 mm (two on the left and right sides), or the long width 1100 mm × short width 285 mm × thickness 90 mm (center). As shown in FIG. 1, the girder 22 is parallel to one side surface (the right side surface or the left side surface) of the loading surface 21 so that the fork of the forklift can be inserted in two directions, and the left and right ends of the lower surface of the loading surface 21. , And at the center thereof, along the insertion direction of the fork.
３本の桁体２２の間であり、且つ積載面２１と地面との間には、図１に示すように、フォークリフトのフォークが差し込まれるフォーク差し込み部２３が形成される。フォーク差し込み部２３は、フォークの差し込み方向の両側に開放しており、本実施の形態１ではいわゆる２方差しのパレットを構成し、フォーク差し込み部２３にフォークリフトのフォークを差し込むことで、積載面２１に載せられた荷物が運搬・昇降される。なお、図２（ｄ）に示すように、桁体２２は、その下面側において肉抜き（軽量化）のための凹部２２ａが複数形成される。また、桁体２２の下面に、フォークリフトを用いた複数回の運搬による発泡スチロールの劣化や屑ごみの発生を防止するため、硬化性樹脂、木材、金属などから成るカバー部を取り付けることもできる。 As shown in FIG. 1, a fork insertion portion 23 into which a fork of a forklift is inserted is formed between the three beams 22 and between the loading surface 21 and the ground. The fork insertion part 23 is open on both sides in the fork insertion direction. In the first embodiment, a so-called two-way pallet is formed, and a fork of a forklift is inserted into the fork insertion part 23 to load the loading surface 21. The baggage placed on is transported and lifted. As shown in FIG. 2D, the beam body 22 is formed with a plurality of recesses 22a for lightening (weight reduction) on the lower surface side. In addition, a cover portion made of a curable resin, wood, metal, or the like can be attached to the lower surface of the girder 22 in order to prevent the deterioration of foamed polystyrene and the generation of debris due to multiple transports using a forklift.
パレット本体２の積載面２１の上面には、補強材３が埋め込まれる形状を有し、且つ桁体２２の間に差し込まれるフォークリフトのフォークの差し込み方向（若しくは桁体２２）と略直交する方向で複数（本実施の形態１では６か所）の凹溝２１ａが並設されている。この凹溝２１ａに補強材３を埋め込むことにより、発泡パレット１の左右方向の強度を上げることができ、また補強材３は凹溝２１ａから容易に着脱可能であるために非常に扱いがよい。なお、補強材３は、図１に示す場合、細長い板形状を有する木材を用いているが、その他、所定強度以上の細長い樹脂材や金属材を用いることもできる。 The top surface of the loading surface 21 of the pallet body 2 has a shape in which the reinforcing material 3 is embedded, and is in a direction substantially orthogonal to the fork lift direction (or the beam body 22) of the forklift that is inserted between the beam bodies 22. A plurality of (six in the first embodiment) concave grooves 21a are arranged in parallel. By embedding the reinforcing material 3 in the concave groove 21a, the strength in the left-right direction of the foaming pallet 1 can be increased, and the reinforcing material 3 can be easily detached from the concave groove 21a, so that it is very easy to handle. In the case shown in FIG. 1, the reinforcing material 3 is made of wood having an elongated plate shape, but an elongated resin material or metal material having a predetermined strength or more can also be used.
凹溝２１ａの深さは、パレット本体２の積載面２１の肉厚（及び補強材３の高さ）と同じであり、図２（ｄ）に示すように、凹溝２１ａは積載面２１を上下方向に貫通する貫通孔２１ｂを形成する。この構成により、フォークリフトを用いて積載面２１に載置された荷物を運搬する際に、フォークリフトのフォークが補強材３に直接接触し、補強材３を介して発泡パレット１の左右方向の強度を所定以上に保つことが可能となる。その結果、発泡パレット１が軋みにくくなり、荷物の重量を受けて破断しにくくなる。そして、発泡パレット１は、例えば、フォークリフトを用いて積載量１．２ｔの荷物を、２０ｋｍ／ｈの速さで運搬できる強度を有する。 The depth of the concave groove 21a is the same as the thickness of the stacking surface 21 of the pallet body 2 (and the height of the reinforcing material 3). As shown in FIG. A through hole 21b penetrating in the vertical direction is formed. With this configuration, when the load placed on the loading surface 21 is transported using a forklift, the fork of the forklift comes into direct contact with the reinforcing material 3, and the strength in the left-right direction of the foam pallet 1 is increased via the reinforcing material 3. It becomes possible to keep above a predetermined value. As a result, the foam pallet 1 is difficult to squeeze, and is difficult to break due to the weight of the load. And the foaming pallet 1 has the intensity | strength which can carry the load of the load capacity of 1.2t at a speed | rate of 20 km / h, for example using a forklift.
凹溝２１ａの内側面には、図２（ｂ）や図３の拡大図に示すように、上下方向に延びる凸部２１ｃが所定間隔で複数形成されている。これにより、凹溝２１ａに嵌め込まれた補強材３が凸部２１ｃに係止されて、補強材３が凹溝２１ａから脱落することを防止できる。例えば、凹溝２１ａの短手方向幅Ｙ１が１７ｍｍならば、凸部２１ｃ間の幅Ｙ２は１４ｍｍとなる。なお、補強材３の脱落を防止するために粘着テープを用いることもできる。 As shown in the enlarged view of FIG. 2B or FIG. 3, a plurality of convex portions 21c extending in the vertical direction are formed at predetermined intervals on the inner surface of the concave groove 21a. Thereby, the reinforcing material 3 fitted in the concave groove 21a is locked to the convex portion 21c, and the reinforcing material 3 can be prevented from falling off the concave groove 21a. For example, if the lateral direction width Y1 of the concave groove 21a is 17 mm, the width Y2 between the convex portions 21c is 14 mm. An adhesive tape can be used to prevent the reinforcing material 3 from falling off.
図２（ｂ）に示すように、追う溝２１ａの長手方向の両端部には、追う溝２１ａより幅広となる幅広溝２１ｄが形成される。これにより、補強材３を凹溝２１ａから着脱する際に指を幅広溝２１ｄに入れることができ、作業性を向上できる。 As shown in FIG. 2B, wide grooves 21d that are wider than the chasing groove 21a are formed at both ends in the longitudinal direction of the chasing groove 21a. Thereby, when attaching and detaching the reinforcing material 3 from the concave groove 21a, a finger can be put into the wide groove 21d, and workability can be improved.
次に、発泡パレット１の使用後の状態を、図４を参照して説明する。最初に、図４（ａ），（ｂ）に示すように、各補強材３を凹溝２１ａから取り出して分別する。そして、図４（ｃ）に示すように、パレット本体２を、凹溝２１ａに沿って裁断することができ、この結果、使用後において発泡パレット１の容積を減容してから容易に廃棄処理できる。 Next, the state after use of the foam pallet 1 will be described with reference to FIG. First, as shown in FIGS. 4A and 4B, the reinforcing members 3 are taken out from the concave grooves 21a and separated. And as shown in FIG.4 (c), the pallet main body 2 can be cut | judged along the ditch | groove 21a, As a result, after the volume reduction of the foaming pallet 1 is reduced after use, it can be easily disposed of. it can.
次に、発泡パレット１の重量に関して述べる。発泡パレット１を構成する発泡合成樹脂のパレット本体２は約１ｋｇであり、複数の木材である補強材３の合計は１ｋｇ程度であり、この結果、発泡パレット１の重量をおおよそ２ｋｇ前後にできる。これは、従来の木製パレット約１０ｋｇと比較しても飛躍的に軽量化できており、作業性を向上できる。 Next, the weight of the foam pallet 1 will be described. The pallet body 2 of the foamed synthetic resin constituting the foam pallet 1 is about 1 kg, and the total of the reinforcing members 3 made of a plurality of wood is about 1 kg. As a result, the weight of the foam pallet 1 can be about 2 kg. This is drastically reduced in weight compared to a conventional wooden pallet of about 10 kg, and the workability can be improved.
次に、発泡パレット１を用いた曲げ実験データを図５の表４に示す。ここでは、実験データとして、比較のために（Ａ）発泡倍率６０倍の発泡スチロール製のパレット、（Ｂ）発泡倍率４０倍の発泡スチロール製のパレット、（Ｃ）発泡倍率２０倍の発泡スチロール製のパレットを用いる。また、本実施の形態１に係る発泡パレット１として、（Ｄ）発泡倍率６０倍のパレット本体２と補強材３として樹脂材を用いたパレット、及び（Ｅ）発泡倍率６０倍のパレット本体２と補強材３として木材を用いたパレットを用いた。 Next, bending test data using the foam pallet 1 is shown in Table 4 of FIG. Here, as experimental data, for comparison, (A) a polystyrene-made pallet with a foaming ratio of 60 times, (B) a polystyrene-made pallet with a foaming ratio of 40 times, and (C) a polystyrene-made pallet with a foaming ratio of 20 times. Use. Further, as the foam pallet 1 according to the first embodiment, (D) a pallet main body 2 having a foaming magnification of 60 times and a pallet body 2 using a resin material as the reinforcing material 3, and (E) a pallet main body 2 having a foaming magnification of 60 times A pallet using wood was used as the reinforcing material 3.
実験の結果、図５の４１〜４３に示すように、単に発泡スチロール製のパレットの発泡倍率を変えても許容重量に大きな改善は見られず、発泡スチロール製のパレットではフォークリフトを用いた荷物の運搬に使用できないことが分かる。一方、本実施の形態１に係る（Ｄ）及び（Ｅ）の発泡パレット１では、４４，４５に示すように、フォークリフトを用いた荷物の運搬に使用され得る許容重量（特に木材を補強材３として使用した（Ｅ））を有していることが確認できた。 As a result of the experiment, as shown by 41 to 43 in FIG. 5, even if the expansion ratio of the polystyrene foam pallet is simply changed, there is no significant improvement in the allowable weight. It turns out that it cannot be used. On the other hand, in the foamed pallet 1 of (D) and (E) according to the first embodiment, as shown in 44 and 45, an allowable weight that can be used for carrying a load using a forklift (particularly wood is used as the reinforcing material 3). It was confirmed that (E)) used as
次に、本実施の形態１に係る発泡パレット１の具体的な使用例に関して、図６に示す写真を参照して説明する。 Next, a specific usage example of the foaming pallet 1 according to the first embodiment will be described with reference to a photograph shown in FIG.
図６（ａ），（ｂ）に示すように、発泡合成樹脂製のパレット５を用いる場合には、重量物を載置しながらフォークリフトで運搬すると、重量物の荷重に耐えることができずに破壊してしまう。一方、図６（ｃ），（ｄ）に示すように、木材の補強材３を用いた発泡パレット１を用いる場合、重量物１．２ｔを載置しても、フォークリフトの運搬中の振動によっても発泡パレット１が破断することがなく、強度を保っていることが確認できた。なお、図６（ｃ）に示すように荷物にストレッチフィルムを巻くことで荷物の安定性を増加できる。 As shown in FIGS. 6 (a) and 6 (b), when using a pallet 5 made of foamed synthetic resin, if a heavy load is placed and transported by a forklift, it cannot withstand the load of the heavy load. It will destroy. On the other hand, as shown in FIGS. 6 (c) and 6 (d), when using the foam pallet 1 using the wood reinforcing material 3, even if a heavy load 1.2 t is placed, it is caused by vibration during transportation of the forklift. It was also confirmed that the foam pallet 1 was not broken and kept strong. In addition, as shown in FIG.6 (c), the stability of a load can be increased by winding a stretch film around a load.
次に、本実施の形態１に係る発泡パレット１のパレット本体２の製造方法に関して、図７を参照して説明する。 Next, a method for manufacturing the pallet body 2 of the foam pallet 1 according to the first embodiment will be described with reference to FIG.
パレット本体２の製造装置６は、パレット本体２の形状に合わせた雄型６０及び雌型６１が開閉可能に構成される金型から成る。この金型は比較的安価となる。雄型６０は、全体として開閉方向に沿って凸状に形成された凸状部を有し、パレット本体２の上面の凹溝２１ａなどの溝形状に合わせた別部材たるコマ６２が取り付けられる。なお、このコマ６２は、他の形状のコマに変更、及びその位置を変更することが可能となっている。雌型６１は、全体では雄型６０を開閉方向に沿って差し入れ可能に形成された凹状部を有し、フォークの差し込み口の形状が形成されている。なお、雄型６０及び雌型６１の壁面には、多数の蒸気孔が形成されている。 The manufacturing apparatus 6 for the pallet main body 2 is composed of a mold configured so that a male mold 60 and a female mold 61 adapted to the shape of the pallet main body 2 can be opened and closed. This mold is relatively inexpensive. The male mold 60 has a convex portion formed in a convex shape along the opening / closing direction as a whole, and a frame 62 as a separate member is attached to the groove shape such as the concave groove 21a on the upper surface of the pallet main body 2. The top 62 can be changed to a top of another shape and its position can be changed. The female die 61 as a whole has a concave portion formed so that the male die 60 can be inserted along the opening and closing direction, and the shape of the insertion port of the fork is formed. A number of vapor holes are formed in the wall surfaces of the male mold 60 and the female mold 61.
そして、最初に、金型である雄型６０及び雌型６１を閉じることにより形成される成形空間に、発泡性合成樹脂粒子を充填する。次に、蒸気室に蒸気を供給して金型を温めると共に、蒸気孔を介して蒸気を成形空間内に供給し、発泡性合成樹脂粒子を加熱してパレット本体２の発泡成形をする。その後、金型を冷却し、金型を開放する。そして、最後に、成形されたパレット本体２を金型から離型して外部に取り出す。 First, the foaming synthetic resin particles are filled into a molding space formed by closing the male mold 60 and the female mold 61 which are molds. Next, steam is supplied to the steam chamber to warm the mold, and steam is supplied into the molding space through the steam holes, and the foamable synthetic resin particles are heated to foam-mold the pallet body 2. Thereafter, the mold is cooled and the mold is opened. Finally, the molded pallet body 2 is released from the mold and taken out to the outside.
以上の説明のように、本実施の形態１に係る発泡パレット１は、パレット本体２と、補強材３とを備え、パレット本体２は、発泡合成樹脂より成形されて所定の厚みを有する平面視で矩形状の積載面２１と、積載面２１の下面側に設けられる複数の桁体２２とを有し、積載面２１の上面には、補強材３を埋め込むための凹溝２１ａが形成される。具体的には、積載面２１と桁体２２とは発泡合成樹脂により一体成形されてパレット本体２を成して、補強材３は、細長い板形状の木材であり、凹溝２１ａは、補強材３が埋め込まれる形状を有し、且つ桁体２２の間に差し込まれるフォークリフトのフォークの差し込み方向と略直交する方向に複数並列で形成される。 As described above, the foaming pallet 1 according to the first embodiment includes the pallet main body 2 and the reinforcing material 3, and the pallet main body 2 is formed from foamed synthetic resin and has a predetermined thickness in plan view. The rectangular loading surface 21 and a plurality of girders 22 provided on the lower surface side of the loading surface 21 are formed. On the upper surface of the loading surface 21, a concave groove 21a for embedding the reinforcing material 3 is formed. . Specifically, the loading surface 21 and the girder 22 are integrally formed of foamed synthetic resin to form the pallet main body 2, the reinforcing material 3 is an elongated plate-shaped wood, and the concave groove 21a is a reinforcing material. 3 is embedded and formed in parallel in a direction substantially orthogonal to the insertion direction of the fork of the forklift inserted between the girders 22.
この構成により、発泡パレット１は、従来にない新しいタイプのものであり、低価格であり、非常に軽量で作業性が良く、且つ重量物を積載できる充分な強度を有するパレットとなる。 With this configuration, the foamed pallet 1 is a new type that has not been heretofore, and is a low-price, extremely light weight, good workability, and a pallet that has sufficient strength to load heavy objects.
より具体的には、発泡パレット１は、発泡合成樹脂より成形されたパレット本体２と、木材の補強材３から成るために、部品点数や製造工数を低減し、コストダウンを図ることができる。また、パレット本体２は、発泡合成樹脂で成型されているため、非常に軽量（例えば２ｋｇ）で作業性が極めて良い。また、補強材３の凹溝２１ａへの取り付け・取り外しが非常に容易である。 More specifically, since the foam pallet 1 is composed of a pallet main body 2 formed of foamed synthetic resin and a wood reinforcing material 3, it is possible to reduce the number of parts and manufacturing man-hours and to reduce the cost. Moreover, since the pallet main body 2 is shape | molded with the foaming synthetic resin, it is very lightweight (for example, 2 kg) and workability | operativity is very good. Further, the attachment / detachment of the reinforcing material 3 to / from the concave groove 21a is very easy.
さらに、発泡パレット１は、補強材３がフォークリフトのフォークの差し込み方向に直交するように積載面２１の凹溝２１ａに嵌め込まれるために、フォークリフトの運搬中に際しても重量物を積載できる充分な強度を有する。 Furthermore, since the foaming pallet 1 is fitted in the concave groove 21a of the loading surface 21 so that the reinforcing material 3 is orthogonal to the insertion direction of the fork of the forklift, the foaming pallet 1 has sufficient strength to load heavy objects even during transport of the forklift. Have.
またさらに、発泡パレット１のパレット本体２は、発泡合成樹脂で成型されているために、その使用後においては凹溝２１ａに沿って容易に裁断して廃棄でき、容積を取ることがない。 Furthermore, since the pallet main body 2 of the foaming pallet 1 is molded from the foamed synthetic resin, after use, the pallet body 2 can be easily cut and discarded along the concave groove 21a and does not take up a volume.
