【従来の技術】
最近立体自動倉庫内に於いて、合成樹脂製パレット上に種々の物品を載せ、合成樹脂製パレットの両端部をラックの荷受材に載せて保管することが行われている。
【０００３】
ところが、阪神大震災の際に立体倉庫内のラック上に載せたパレットが該荷受材から外れて荷物が落下する事故が発生した。従来の一体成形された両面使用二方差し合成樹脂製パレットは、ラックの荷受材を載せた場合に地震等で落下することを想定して滑らないような構成となっていない。かかるパレットでは、表裏のデッキボード面に滑り止め材が取り付けられるものの、パレットの強度の面から中間部の筒状桁の補強Ｕ字桟がフォークの挿入方向に対して垂直となるように形成されており、しかも一体成形により表面部と裏面部とに形成されたＵ字桟（滑り止め材取り付け孔を有する）が互いに上下に重なり合わないように成形されるため、取り付けられた滑り止め材が表裏面ではどちらかが表裏面の端部からより離れた位置に設置されることになり、該パレットをラックの荷受材に載せた時に端部からより離れた位置に設置された滑り止め材が該荷受材の上に乗らず、地震等の振動でラックから落下するという問題が解消していない。

BACKGROUND OF THE INVENTION
The present invention relates to a double-sided two-way insert integral-molded synthetic resin pallet that can be suitably used when various articles are stored in a three-dimensional automatic warehouse.
[0002]
[Prior art]
Recently, in a three-dimensional automatic warehouse, various articles are placed on a synthetic resin pallet, and both ends of the synthetic resin pallet are placed on a rack receiving material and stored.
[0003]
However, during the Great Hanshin Earthquake, an accident occurred in which a pallet placed on a rack in a three-dimensional warehouse was detached from the load receiving material and the luggage dropped. Conventional single-sided two-way synthetic resin pallets that are integrally molded do not have a structure that does not slip on the assumption that they will fall due to an earthquake or the like when a rack receiving material is placed. In such a pallet, the anti-slip material is attached to the front and back deck board surfaces, but the reinforcing U-shaped beam of the intermediate cylindrical girder is formed perpendicular to the insertion direction of the fork in terms of the strength of the pallet. In addition, since the U-shaped crosspieces (having anti-slip material attachment holes) formed on the front surface portion and the back surface portion by integral molding are formed so as not to overlap each other, the attached anti-slip material is One of the front and back sides will be installed at a position farther from the end of the front and back, and when the pallet is placed on the load receiving material of the rack, an anti-slip material installed at a position farther from the end will be The problem of falling on the load receiving material and falling from the rack due to vibration such as an earthquake has not been solved.
[0004]
[Problems to be solved by the invention]
The present inventors have used both sides where the end of the synthetic resin pallet is difficult to come off from the load receiving material of the rack when subjected to vibration due to an earthquake or the like, even when using both front and back surfaces in a three-dimensional automatic warehouse. As a result of research on the pallet made of one-piece molded plastic, the present invention has been achieved.
[0005]
[Means for Solving the Problems]
The present invention relates to a front surface portion, a back surface portion, a side tubular girder formed on both sides connecting the front surface portion and the back surface portion, and a middle tube formed in the middle of both side cylindrical girders. In a two-sided two-piece integral molding synthetic resin pallet with a fork insertion hole formed between the cylindrical girders, each end of the front and back sides of the intermediate cylindrical girder At least one anti-slip material is provided along the edge at the position inside the area, and the anti-slip material on the front surface and the back surface overlaps each other at approximately the same distance from each other. The present invention relates to a double-sided two-way synthetic resin pallet characterized by being attached at a position that does not match.
[0006]
The present invention forms a U-shaped beam having a through hole for attaching a slip stopper to the front surface portion and the back surface portion in parallel with the fork insertion port at a position inside the cylindrical girder of the intermediate portion inward from the end portion. Further, the present invention relates to the double-sided two-sided synthetic resin pallet in which the U-shaped crosspieces of the front surface portion and the back surface portion are positioned so as not to overlap each other and a slip stopper is attached to the through hole.
[0007]
The present invention provides the double-sided use in which partition walls for connecting the front surface portion and the back surface portion are respectively formed at both ends of the U-shaped crosspiece in the intermediate cylindrical girder, and the partition walls are perpendicular to the fork insertion holes. The present invention relates to a two-way synthetic resin pallet.
[0008]
The present invention enters the inside from the same pallet edge as the anti-slip installed on the front surface and the back surface of the cylindrical beam at the middle in the front surface and the back surface of the cylindrical beam at each corner. The present invention relates to the double-sided two-way synthetic resin pallet in which each slip stopper is installed at a position.
