Description
【０００１】[0001]
本考案は、パレットに関し、詳しくはデッキボードに合成樹脂発泡板を利用し たパレットに関する。 The present invention relates to a pallet, and more particularly to a pallet using a synthetic resin foam plate for a deck board.
【０００２】[0002]
工場等において生産された製品を保管したり出荷する際に、製品を載せて移動 する等の目的で用いられるパレットは、従来、主として木製のものが用いられて いたが、木製のパレットに比べて軽量で取扱が容易であり、しかも汚れ難く衛生 的である等の理由で近年、合成樹脂発泡体製のパレットが多く用いられるように なっている。 Conventionally, wooden pallets have been mainly used as a pallet for the purpose of loading and moving the product when storing or shipping the products produced in factories, but compared to wooden pallets. In recent years, pallets made of synthetic resin foam have been widely used because of their light weight, ease of handling, stain resistance and hygiene.
【０００３】 合成樹脂発泡体製のパレットとして、例えば発泡倍率２〜５倍程度の２枚の合 成樹脂発泡体からなるデッキボード間に、筒状の脚部を適宜間隔を隔てて複数個 挟み込んで接着し、更に上下のデッキボード表面側から筒状脚部の中空部を貫通 するボルトナット等で固定した構造のパレット（実開昭４７−２６８５２号）、 発泡倍率１〜６倍の合成樹脂発泡板からなる表面層、裏面層との間にハニカム芯 材を挟み込んで一体化したハニカム構造のデッキボードの裏面層側に嵌合凹部を 設け、該嵌合凹部に脚部の嵌合凸部を嵌め込んで熱融着する等によって２枚のデ ッキボードと脚部とを一体化した構造のパレット（実開昭５７−１９６６４２号 ）等が知られている。As a pallet made of synthetic resin foam, for example, a plurality of tubular legs are sandwiched at appropriate intervals between deck boards made of two synthetic resin foams having an expansion ratio of about 2 to 5 times. The pallet (actually No. 47-26852), which is adhered with, and fixed with bolts and nuts that penetrate the hollow parts of the cylindrical legs from the upper and lower deck board surface sides, synthetic resin with a foaming ratio of 1 to 6 times. A mating recess is provided on the back layer side of a deck board having a honeycomb structure in which a honeycomb core material is sandwiched between a front surface layer and a back surface layer made of a foam plate, and the fitting convex portion of the leg is provided in the fitting recess. There is known a pallet having a structure in which two deck boards and legs are integrally formed by fitting and heat-sealing (Saikai Sho 57-196642) and the like.
【０００４】 上記従来の合成樹脂発泡体製パレットでは、デッキボードと、脚部との接合強 度を更に高めるために、接着や熱融着とともに、ボルトナット等による固定や、 嵌合凹部に脚部の嵌合凸部を嵌合させる等の手段を併用している。In the above-mentioned conventional synthetic resin foam pallet, in order to further increase the bonding strength between the deck board and the legs, adhesion and heat fusion, fixing with bolts and nuts, and legs in the fitting recesses are performed. The means for fitting the fitting convex portion of the section are also used.
【０００５】[0005]
しかしながら、デッキボードを構成する合成樹脂発泡体に、直接脚部を接着或 いは熱融着している従来の合成樹脂発泡体製パレットでは、ボルトナット等によ る固定や、嵌合等の手段を併用したとしても、充分な接合強度を得られるのは、 発泡体が６倍程度以下の低発泡倍率の場合であって、それ以上の高発泡倍率の発 泡体を用いた場合、パレットに負荷が加わった際に発泡体の脚部との接合部分が 破損し易くなる等の問題があった。従って、従来の合成樹脂発泡体製パレットで は、低発泡倍率の発泡体を使用せざるを得ず、このため合成樹脂発泡体製パレッ トの特徴である軽量性が充分に生かされていなかった。 However, in the conventional synthetic resin foam pallet in which the legs are directly bonded or heat-sealed to the synthetic resin foam that constitutes the deck board, fixing with bolts and nuts, fitting, etc. Even if the means are used together, sufficient bonding strength can be obtained when the foam has a low expansion ratio of about 6 times or less, and when a foaming body having a higher expansion ratio is used, the pallet When a load was applied to the foam, there was a problem that the joint of the foam and the leg was easily damaged. Therefore, in the conventional synthetic resin foam pallet, it is unavoidable to use a foam having a low expansion ratio, and therefore the lightness characteristic of the synthetic resin foam pallet has not been fully utilized. .
【０００６】 また実開昭４７−２６８５２号に記載されているパレットのように、接着の他 にボルトナット等による固定手段を併用すると、パレットの組み立て作業が煩雑 となるという問題もあった。Further, as in the pallet described in Japanese Utility Model Application Laid-Open No. 47-26852, if a fixing means such as a bolt and nut is used in addition to the adhesion, there is a problem that the work of assembling the pallet becomes complicated.
【０００７】 本考案は上記の点に鑑みなされたもので、従来に比して高発泡倍率の合成樹脂 発泡体をデッキボードに用い、軽量性に優れるとともにデッキボードと脚部との 接合強度に優れた堅牢なパレットを提供することを目的とする。The present invention has been made in view of the above points, and uses a synthetic resin foam body having a higher expansion ratio than that of a conventional one for a deck board, which is excellent in lightness and is excellent in the bonding strength between the deck board and the legs. The purpose is to provide an excellent and robust pallet.

It is preferably formed by laminating a reinforcing material which is not provided.
【０００９】 また本考案のパレットにおける脚部として、中空の筒状のものを用いることが 好ましい。また少なくとも一端部が開口した筒状或いは両端が開口した管状の脚 部を用いることができ、この場合には、脚部の内空部に接合補助材を挿入し、脚 部の開口側を接合補助材とともにデッキボード裏面に接合することにより、デッ キボードと脚部とを一体化することができる。Further, it is preferable to use hollow cylindrical ones as the leg portions in the pallet of the present invention.

【００２３】 接合補助材７としては、上記補強材の説明で例示したものと同様のものが用い られる。接合補助材７は厚い方が、脚部３との間の接合面積が広くなって接合力 が高められるため好ましいが、必要以上に厚くしても、それに相応する接合力の 向上は望めなくなるとともに、補助材７の材質によってはパレット１の重量増加 に影響を及ぼしたり、材料費の上昇をきたすため、接合補助材７の厚みは１〜１ ５mm程度が好ましい。As the joining auxiliary material 7, the same materials as those exemplified in the above description of the reinforcing material are used. It is preferable that the joining auxiliary member 7 is thicker because the joining area with the leg portion 3 becomes wider and the joining force is enhanced, but even if it is made thicker than necessary, the corresponding improvement in joining force cannot be expected. Depending on the material of the auxiliary material 7, the weight of the pallet 1 may be increased or the material cost may be increased, so that the thickness of the auxiliary material 7 is preferably about 1 to 15 mm.
【００２４】 脚部３とデッキボード２とは、脚部３や補強材層６が同質の合成樹脂等の場合 には熱融着や接着により接合することができ、それ以外の場合には接着によって 接合する。接着剤としては、ホットメルト系接着剤、ポリマーエマルジョン系接 着剤、二液混合型接着剤、架橋型接着剤等の中から、脚部３と補強剤層６等との 材質に応じ、接着力の優れたものを適宜選択して用いる。The leg portion 3 and the deck board 2 can be joined by heat fusion or adhesion when the leg portion 3 and the reinforcing material layer 6 are made of a synthetic resin or the like of the same quality. Join by. As the adhesive, a hot-melt adhesive, a polymer emulsion adhesive, a two-component mixed adhesive, a cross-linking adhesive, or the like is used depending on the material of the leg portion 3 and the reinforcing layer 6 and the like. The one with excellent power is appropriately selected and used.
【００２５】 図４は本考案のパレットの他の実施例を示すもので、図４に示すパレット１で は、裏面側の補強材層６に脚部取り付け凹部を設けておらず、このような場合に は、脚部３の接合強度を高めるために、一端が開口した筒状や両端が開口した管 状の脚部３を用い、接合補助材７を併用して接合することが必要となる。FIG. 4 shows another embodiment of the pallet of the present invention. In the pallet 1 shown in FIG. 4, the leg portion mounting recess is not provided in the reinforcing material layer 6 on the back surface side. In this case, in order to increase the joining strength of the leg portion 3, it is necessary to use a tubular leg portion 3 with one end open or a tubular shape with both ends open, and jointly use the joining auxiliary material 7. .

以上説明したように、本考案のパレットは、発泡倍率７倍以上の発泡体の表裏 両面に補強材層を積層してデッキボードを構成し、このデッキボード裏面側の補 強材層に脚部を接合一体化したため、デッキボードを構成する発泡体が高発泡倍 率であっても脚部とデッキボードとの接合強度に優れ、軽量性、堅牢性に優れて いる。また裏面側の補強材層に、脚部端部の形状を有する非貫通状の脚部取り付 け凹部を設け、該凹部内に脚部端部を挿入せしめて脚部を接合することにより、 更に脚部の接合強度が高められる。また脚部取り付け凹部は、脚部端部の形状を 有する貫通孔を有する補強材と、脚部取り付け部に貫通孔を有していない補強材 とを積層することによって効率良く形成することができる。 As described above, in the pallet of the present invention, a reinforcing material layer is laminated on both front and back surfaces of a foam having a foaming ratio of 7 times or more to form a deck board, and the reinforcing material layer on the back side of the deck board is formed with legs. Since the deck and the foam that make up the deck board have a high foaming ratio, the strength of the joint between the legs and the deck board is excellent, and the lightweight and robustness is excellent. In addition, by providing a non-penetrating leg mounting recess having the shape of the end of the leg on the back side, and inserting the leg end into the recess and joining the legs, Further, the joint strength of the legs is increased. The leg mounting recess can be efficiently formed by stacking a reinforcing material having a through hole having the shape of the end of the leg and a reinforcing material having no through hole in the leg mounting portion. .
【００２９】 本考案のパレットは、脚部として中空状のものや一端が開口した筒状のもの或 いは両端が開口した管状のもの等を用いると、軽量で好ましい。また一端が開口 した筒状の脚部や両端が開口した管状の脚部を用い、開口側の端部をデッキボー ドに接合する場合、脚部の内空部に接合補助材を挿入させ、この接合補助材とと もに脚部を接合すると、脚部の接合強度が更に高められる等の効果を有する。The pallet of the present invention is preferably lightweight because it uses a hollow leg, a tubular end with one end open, or a tubular end with both ends open. Also, when using a tubular leg with one end open or a tubular leg with both ends open, and when joining the end on the opening side to the deck board, insert a joining auxiliary material into the inner space of the leg, and When the legs are joined together with the joining aid, the joining strength of the legs is further enhanced.
