Description

梱包装置packing equipment
 本開示は、梱包装置に関する。 The present disclosure relates to a packaging device.
 下記特許文献1に圧縮機の梱包装置が開示されている。この圧縮機の梱包装置は、複数の圧縮機を載置したパレットと、各圧縮機の頭部に嵌合した紙管と、各紙管すべてにわたって上部に載置された天板と、パレットと天板を、圧縮機と紙管の嵌合状態を介して挾持する帯状部材を具備する。紙管は、圧縮機との嵌合状態において、下端が圧縮機頭部の上面に当接する内管と、下端部が内管の下端より下方に延出し、圧縮機頭部の周囲を被う外管より構成されている。 A packing device for a compressor is disclosed in Patent Document 1 below. This compressor packaging device consists of a pallet on which multiple compressors are mounted, a paper tube fitted into the head of each compressor, a top plate placed on top of each paper tube, and a pallet and a top plate placed on top of each paper tube. A belt-like member is provided that holds the plate through the fit between the compressor and the paper tube.

 上述した従来の梱包装置では、段積み時に垂直方向の荷重を受けると、その荷重が内管のみに作用する。このため、内管が破損しやすい。内管が破損すると、天板が傾斜して、荷崩れを招く可能性がある。 In the conventional packaging apparatus described above, when a vertical load is applied during stacking, that load acts only on the inner tube. Therefore, the inner tube is easily damaged. If the inner tube is damaged, the top plate may tilt and the load may collapse.

実施の形態1.
 図1は、実施の形態1による梱包装置1を示す分解斜視図である。図1に示す梱包装置1は、物体90の梱包に用いられる。物体90は、例えば電気機器でもよい。物体90は、例えば、空調機に用いられる圧縮機でもよい。
Embodiment 1.
FIG. 1 is an exploded perspective view showing a packaging device 1 according to a first embodiment. The packaging device 1 shown in FIG. 1 is used for packaging an object 90. Object 90 may be an electrical device, for example. The object 90 may be, for example, a compressor used in an air conditioner.
 図1に示すように、本実施の形態では、一つのパレット11の上に、複数の物体90を、三段に積み重ねた状態で梱包する。以下、梱包装置1により物体90を梱包する手順の例について説明する。まず、パレット11の上面に平板12が置かれる。平板12は、例えばベニヤ板でもよい。平板12の上に底トレイ13が置かれる。底トレイ13の上面に底部シート14が置かれる。底部シート14には、複数の物体90の下部が嵌合する複数の切欠き部が形成されている。一段目を形成する複数の物体90のそれぞれの下部が、それぞれの切欠き部の内側に嵌合することで、これらの物体90が適正な位置に配置される。 As shown in FIG. 1, in this embodiment, a plurality of objects 90 are stacked in three tiers and packed on one pallet 11. An example of a procedure for packaging an object 90 using the packaging device 1 will be described below. First, the flat plate 12 is placed on the upper surface of the pallet 11. The flat plate 12 may be, for example, a plywood board. A bottom tray 13 is placed on the flat plate 12. A bottom sheet 14 is placed on top of the bottom tray 13. The bottom sheet 14 is formed with a plurality of notches into which the lower portions of the plurality of objects 90 fit. The lower portions of the plurality of objects 90 forming the first stage fit inside the respective notches, so that these objects 90 are arranged at appropriate positions.
 次に、一段目を形成する複数の物体90のそれぞれの上に、天部パッド構造体2が置かれる。それらの天部パッド構造体2の上に平板12と底部シート14とが置かれる。その上に、二段目を形成する複数の物体90が置かれる。 Next, the top pad structure 2 is placed on each of the plurality of objects 90 forming the first stage. A flat plate 12 and a bottom sheet 14 are placed on top of the top pad structure 2. A plurality of objects 90 forming a second tier are placed thereon.
 次に、二段目を形成する複数の物体90のそれぞれの上に、天部パッド構造体2が置かれる。それらの天部パッド構造体2の上に平板12と底部シート14とが置かれる。その上に、最上段となる三段目を形成する複数の物体90が置かれる。 Next, the top pad structure 2 is placed on each of the plurality of objects 90 forming the second stage. A flat plate 12 and a bottom sheet 14 are placed on top of the top pad structure 2. A plurality of objects 90 forming a third tier, which is the top tier, are placed thereon.
 次に、三段目を形成する複数の物体90のそれぞれの上に、天部パッド構造体2が置かれる。そして、パレット11の上に積まれた物体90及び天部パッド構造体2等の周囲を外側から覆うように、側面スリーブ15が底トレイ13の上面に置かれる。側面スリーブ15は、例えば紙製でもよい。 Next, the top pad structure 2 is placed on each of the plurality of objects 90 forming the third tier. Then, the side sleeve 15 is placed on the top surface of the bottom tray 13 so as to cover the objects 90 stacked on the pallet 11, the top pad structure 2, etc. from the outside. The side sleeve 15 may be made of paper, for example.
 さらに、最上段の天部パッド構造体2の上に平板12が置かれる。その平板12の上に、天蓋17が置かれる。最後に、バンド(図示省略)にてパレット11と天蓋17とを締結する。バンドは、例えばポリプロピレンバンドでもよい。 Furthermore, a flat plate 12 is placed on top of the top pad structure 2. A canopy 17 is placed on top of the flat plate 12. Finally, the pallet 11 and the canopy 17 are fastened together with a band (not shown). The band may be, for example, a polypropylene band.
 図2は、実施の形態1による梱包装置1が備える天部パッド構造体2の平面図と断面側面図である。図2に示すように、天部パッド構造体2は、筒状の外側部材3と、外側部材3の内面に固定された内側部材4とを有する。外側部材3及び内側部材4のそれぞれは、紙製である。外側部材3及び内側部材4を紙製にすることで、樹脂製の場合よりも、環境保全の観点で優れる。外側部材3及び内側部材4のそれぞれは、紙管でもよい。外側部材3及び内側部材4のそれぞれは、紙管原紙から作られたものでもよい。 FIG. 2 is a plan view and a cross-sectional side view of the top pad structure 2 included in the packaging apparatus 1 according to the first embodiment. As shown in FIG. 2, the top pad structure 2 includes a cylindrical outer member 3 and an inner member 4 fixed to the inner surface of the outer member 3. Each of the outer member 3 and the inner member 4 is made of paper. Making the outer member 3 and the inner member 4 made of paper is superior to the case of making them made of resin from the viewpoint of environmental conservation. Each of the outer member 3 and the inner member 4 may be a paper tube. Each of the outer member 3 and the inner member 4 may be made from paper tube base paper.
 外側部材3に内側部材4を固定する方法は特に限定されない。例えば、接着剤を用いて外側部材3に内側部材4を固定してもよい。あるいは、外側部材3の内側に内側部材4を圧入することによって両者を固定してもよい。 The method of fixing the inner member 4 to the outer member 3 is not particularly limited. For example, the inner member 4 may be fixed to the outer member 3 using an adhesive. Alternatively, both may be fixed by press-fitting the inner member 4 inside the outer member 3.
 本実施の形態では、外側部材3及び内側部材4のそれぞれは、平面視において、中心軸AXを中心とする円形の形状を有する。 In this embodiment, each of the outer member 3 and the inner member 4 has a circular shape centered on the central axis AX in plan view.
 図3は、実施の形態1による梱包装置1のうちの一つの物体90とその上の天部パッド構造体2を示す断面側面図である。図3に示すように、梱包装置1により梱包される物体90は、頂部91と、突出部92と、本体部93とを有する。頂部91は、凸曲面を形成する。突出部92は、頂部91の周囲において横方向すなわち水平方向に突出する。突出部92は、中心軸AXを中心とする環状のリブでもよい。本体部93は、中心軸AXを中心とする円筒状の外形を有する。本体部93は、頂部91の下方に位置する。突出部92は、頂部91と本体部93との境界に位置する。突出部92の外径は、頂部91の外径よりも大きい。突出部92の外径は、本体部93の外径よりも大きい。梱包装置1が水平な床に置かれると、中心軸AXは、鉛直線に対して平行になる。 FIG. 3 is a cross-sectional side view showing one object 90 of the packaging apparatus 1 according to the first embodiment and the top pad structure 2 thereon. As shown in FIG. 3, an object 90 to be packed by the packing device 1 has a top portion 91, a protrusion 92, and a main body portion 93. The top portion 91 forms a convex curved surface. The protruding portion 92 protrudes laterally, that is, horizontally, around the top portion 91 . The protruding portion 92 may be an annular rib centered on the central axis AX. The main body portion 93 has a cylindrical outer shape centered on the central axis AX. The main body portion 93 is located below the top portion 91 . The protruding portion 92 is located at the boundary between the top portion 91 and the main body portion 93. The outer diameter of the protrusion 92 is larger than the outer diameter of the top 91. The outer diameter of the protruding portion 92 is larger than the outer diameter of the main body portion 93. When the packaging device 1 is placed on a horizontal floor, the central axis AX becomes parallel to the vertical line.
 頂部91の凸曲面は、平面曲線を、中心軸AXを回転の軸として回転させることにより得られる回転体に沿う形状を有している。頂部91の凸曲面は、中心軸AXから遠ざかるほど位置が低くなるように傾斜している。 The convex curved surface of the top portion 91 has a shape that follows a rotating body obtained by rotating a plane curve about the central axis AX as the axis of rotation. The convex curved surface of the top portion 91 is inclined such that the position thereof becomes lower as the distance from the central axis AX increases.
 外側部材3は、平板12の下面に接する上端部31と、物体90の突出部92に接する下端部32とを有する。内側部材4は、平板12の下面に接する上端部41と、物体90の頂部91の凸曲面に接する下端部42とを有する。中心軸AXの方向の位置に関して、外側部材3の上端部31は、内側部材4の上端部41と同じ位置にある。 The outer member 3 has an upper end 31 in contact with the lower surface of the flat plate 12 and a lower end 32 in contact with the protrusion 92 of the object 90. The inner member 4 has an upper end 41 in contact with the lower surface of the flat plate 12 and a lower end 42 in contact with the convex curved surface of the top 91 of the object 90. Regarding the position in the direction of the central axis AX, the upper end 31 of the outer member 3 is in the same position as the upper end 41 of the inner member 4.
 天部パッド構造体2は、天部パッド構造体2の上の平板12から、段積みによる垂直荷重を受ける。外側部材3は、物体90の突出部92と、平板12との間で、その垂直荷重を負担する。内側部材4は、物体90の頂部91の凸曲面と、平板12との間で、その垂直荷重を負担する。このように、本実施の形態であれば、外側部材3と内側部材4の両方が垂直荷重を負担することで、段積みによる垂直荷重に対して天部パッド構造体2が確実に耐えることができる。それゆえ、平板12及び天蓋17の水平な姿勢を確実に維持することができるので、荷崩れの発生を確実に防止できる。 The top pad structure 2 receives a vertical load from the flat plate 12 above the top pad structure 2 due to stacking. The outer member 3 bears its vertical load between the protrusion 92 of the object 90 and the flat plate 12. The inner member 4 bears its vertical load between the convex curved surface of the top 91 of the object 90 and the flat plate 12. As described above, in this embodiment, both the outer member 3 and the inner member 4 bear the vertical load, so that the top pad structure 2 can reliably withstand the vertical load due to stacking. can. Therefore, the horizontal posture of the flat plate 12 and the canopy 17 can be maintained reliably, thereby reliably preventing the cargo from collapsing.
 図3に示す例では、内側部材4が物体90の突出部92に接していない。そして、外側部材3の下端部32の内周面が、物体90の頂部91の凸曲面に接している。これにより、輸送時あるいは荷扱い時に、水平方向の衝撃を受けた際に、天部パッド構造体2の位置が水平方向に移動することをより確実に防止できる。また、天部パッド構造体2と、物体90との接触面積が増えることで、摺動面積が分散される。それゆえ、トラック等による物流輸送時に、擦れが抑止される。外側部材3の下端部32の内周面の内径が、物体90の頂部91の外径に、実質的に等しくてもよい。 In the example shown in FIG. 3, the inner member 4 is not in contact with the protrusion 92 of the object 90. The inner circumferential surface of the lower end 32 of the outer member 3 is in contact with the convex curved surface of the top 91 of the object 90. Thereby, it is possible to more reliably prevent the position of the top pad structure 2 from moving in the horizontal direction when receiving a horizontal impact during transportation or cargo handling. Furthermore, by increasing the contact area between the top pad structure 2 and the object 90, the sliding area is distributed. Therefore, chafing is suppressed during physical transportation by trucks or the like. The inner diameter of the inner peripheral surface of the lower end 32 of the outer member 3 may be substantially equal to the outer diameter of the top 91 of the object 90.
 内側部材4の下端部42と、物体90の頂部91の凸曲面との接触面は、外側部材3の中心軸AXに対して、斜めになっている。これにより、天部パッド構造体2と、物体90との接触面積が増えることで、摺動面積が分散される。それゆえ、トラック等による物流輸送時に、擦れが抑止される。また、内側部材4の下端部42と、物体90の頂部91の凸曲面との接触面が、垂直方向の荷重を負担するだけでなく、水平方向の荷重も負担することができる。それゆえ、水平方向の衝撃を受けた際に、天部パッド構造体2の位置が水平方向に移動することをより確実に防止できる。内側部材4の下端部42の内周面の最小内径は、物体90の頂部91の外径よりも小さくてもよい。 The contact surface between the lower end 42 of the inner member 4 and the convex curved surface of the top 91 of the object 90 is oblique with respect to the central axis AX of the outer member 3. This increases the contact area between the top pad structure 2 and the object 90, thereby distributing the sliding area. Therefore, chafing is suppressed during physical transportation by trucks or the like. Further, the contact surface between the lower end 42 of the inner member 4 and the convex curved surface of the top 91 of the object 90 can bear not only a load in the vertical direction but also a load in the horizontal direction. Therefore, when receiving a horizontal impact, the position of the top pad structure 2 can be more reliably prevented from moving in the horizontal direction. The minimum inner diameter of the inner peripheral surface of the lower end portion 42 of the inner member 4 may be smaller than the outer diameter of the top portion 91 of the object 90.
 図2に示すように、本実施の形態における天部パッド構造体2が物体90に装着される前の状態においては、内側部材4の下端部42は、外側部材3の中心軸AXに対して、垂直になっていてもよい。内側部材4の下端部42が、物体90の頂部91の凸曲面に接触したときに、下端部42が凸曲面に押される。その結果、図3に示すように、下端部42が、中心軸AXに対して、斜めになるように変形する。 As shown in FIG. 2, before the top pad structure 2 of this embodiment is attached to the object 90, the lower end portion 42 of the inner member 4 is aligned with respect to the central axis AX of the outer member 3. , may be vertical. When the lower end 42 of the inner member 4 contacts the convex curved surface of the top 91 of the object 90, the lower end 42 is pushed against the convex curved surface. As a result, as shown in FIG. 3, the lower end portion 42 is deformed to be oblique with respect to the central axis AX.
 図2に示す例に代えて、天部パッド構造体2が物体90に装着される前の状態において、内側部材4の下端部42が、外側部材3の中心軸AXに対して、斜めになっていてもよい。すなわち、内側部材4の下端部42が物体90の頂部91の凸曲面に接触する前から、下端部42が中心軸AXに対して斜めになっていてもよい。 Instead of the example shown in FIG. 2, in the state before the top pad structure 2 is attached to the object 90, the lower end portion 42 of the inner member 4 is oblique with respect to the central axis AX of the outer member 3. You can leave it there. That is, the lower end 42 of the inner member 4 may be oblique with respect to the central axis AX even before the lower end 42 contacts the convex curved surface of the top 91 of the object 90.
 内側部材4を構成する材料は、外側部材3を構成する材料と同質の材料でもよい。あるいは、内側部材4を構成する材料は、外側部材3を構成する材料と異質の材料でもよい。例えば、内側部材4を構成する材料は、外側部材3を構成する材料よりも軟質の材料でもよい。内側部材4が比較的軟質であれば、内側部材4の下端部42が、物体90の頂部91の凸曲面に接したときに、その凸曲面の形状に合わせて、内側部材4の下端部42が、より柔軟に変形可能となる。その結果、内側部材4の下端部42と、物体90の頂部91の凸曲面との接触面積が増えやすくなるので、内側部材4が負担できる荷重の大きさが向上する。それゆえ、荷崩れをより確実に防止できる。 The material constituting the inner member 4 may be the same material as the material constituting the outer member 3. Alternatively, the material forming the inner member 4 may be different from the material forming the outer member 3. For example, the material forming the inner member 4 may be softer than the material forming the outer member 3. If the inner member 4 is relatively soft, when the lower end 42 of the inner member 4 comes into contact with the convex curved surface of the top 91 of the object 90, the lower end 42 of the inner member 4 will adjust to the shape of the convex curved surface. However, it can be deformed more flexibly. As a result, the contact area between the lower end portion 42 of the inner member 4 and the convex curved surface of the top portion 91 of the object 90 tends to increase, so that the magnitude of the load that the inner member 4 can bear increases. Therefore, cargo collapse can be more reliably prevented.
 図3に示すように、本実施の形態において、外側部材3の下端部32と、物体90の突出部92との接触面は、外側部材3の中心軸AXに対して、垂直になっている。これにより、外側部材3が負担できる垂直荷重の大きさが向上する。それゆえ、荷崩れをより確実に防止できる。 As shown in FIG. 3, in this embodiment, the contact surface between the lower end 32 of the outer member 3 and the protrusion 92 of the object 90 is perpendicular to the central axis AX of the outer member 3. . This increases the magnitude of the vertical load that the outer member 3 can bear. Therefore, cargo collapse can be more reliably prevented.
 本実施の形態であれば、天部パッド構造体2と物体90との接触面積を増やす上で有利になり、摺動面積が分散される。それゆえ、トラック等による物流輸送時に、製品である物体90の擦れが抑止される。このため、天部パッド構造体2と物体90との間に、擦れ対策として挿入されていたビニールシートを省略することも可能となる。このように、本実施の形態であれば、物流時の品質不良を抑制することが可能となる。 This embodiment is advantageous in increasing the contact area between the top pad structure 2 and the object 90, and the sliding area is distributed. Therefore, the product object 90 is prevented from being rubbed during physical transportation by trucks or the like. For this reason, it is also possible to omit the vinyl sheet inserted between the top pad structure 2 and the object 90 as a measure against rubbing. In this way, with this embodiment, it is possible to suppress quality defects during distribution.
 本実施の形態では、外側部材3の内周の全周にわたって、内側部材4が筒状に配置されている。これにより、内側部材4が負担できる垂直荷重の大きさがさらに向上するので、段積みによる垂直荷重に対して天部パッド構造体2がより確実に耐えることができる。それゆえ、平板12及び天蓋17の水平な姿勢をより確実に維持することができるので、荷崩れの発生をより確実に防止できる。 In this embodiment, the inner member 4 is arranged in a cylindrical shape over the entire inner circumference of the outer member 3. This further increases the magnitude of the vertical load that the inner member 4 can bear, so that the top pad structure 2 can more reliably withstand the vertical load due to stacking. Therefore, the horizontal posture of the flat plate 12 and the canopy 17 can be maintained more reliably, so that the occurrence of cargo collapse can be more reliably prevented.
 本開示では、中心軸AXに対して直交する方向の外側部材3の厚さを、単に「外側部材3の厚さ」と称する。また、中心軸AXに対して直交する方向の内側部材4の厚さを、単に「内側部材4の厚さ」と称する。内側部材4の厚さは、外側部材3の厚さに等しくてもよい。内側部材4の厚さは、外側部材3の厚さよりも薄くてもよい。内側部材4の厚さは、外側部材3の厚さよりも厚くてもよい。 In the present disclosure, the thickness of the outer member 3 in the direction orthogonal to the central axis AX is simply referred to as "thickness of the outer member 3." Further, the thickness of the inner member 4 in the direction perpendicular to the central axis AX is simply referred to as "thickness of the inner member 4." The thickness of the inner member 4 may be equal to the thickness of the outer member 3. The thickness of the inner member 4 may be thinner than the thickness of the outer member 3. The thickness of the inner member 4 may be greater than the thickness of the outer member 3.
 図2に示す例では、本実施の形態における天部パッド構造体2が物体90に装着される前の状態においては、中心軸AXの方向の位置に関して、内側部材4の下端部42は、外側部材3の下端部32よりもやや上方の位置にある。このような例に限らず、天部パッド構造体2が物体90に装着される前の状態において、中心軸AXの方向の位置に関して、内側部材4の下端部42が、外側部材3の下端部32と同じ位置にあってもよい。 In the example shown in FIG. 2, before the top pad structure 2 according to the present embodiment is attached to the object 90, the lower end portion 42 of the inner member 4 is positioned on the outer side with respect to the position in the direction of the central axis AX. It is located slightly above the lower end 32 of the member 3. Not limited to such an example, in a state before the top pad structure 2 is attached to the object 90, the lower end 42 of the inner member 4 is closer to the lower end of the outer member 3 with respect to the position in the direction of the central axis AX. It may be located at the same position as 32.

Embodiment 2.
Next, a second embodiment will be described with reference to FIGS. 4 and 5, but the explanation will focus on the differences from the first embodiment described above, and common explanations will be simplified or omitted. Further, elements common to or corresponding to those described above are given the same reference numerals.
 図4は、実施の形態2による梱包装置1が備える天部パッド構造体2の平面図である。図5は、実施の形態2による梱包装置1が備える天部パッド構造体2の斜視図である。図5に示すように、実施の形態2において、内側部材4は、外側部材3の中心軸AXに対して平行に延びる形状を有する。そして、実施の形態2の天部パッド構造体2においては、内側部材4が配置された領域と、内側部材4が配置されていない領域とが、外側部材3の周方向に沿って交互に存在する。換言すれば、平面視において中心軸AXから放射状に伸びる仮想の複数の線と交差する位置に、内側部材4が配置されている。図示の例では、外側部材3の内周において、中心軸AXを中心とする中心角が、90度ごとの等角度間隔となるように、4箇所に内側部材4が配置されている。本実施の形態2において、それぞれの内側部材4の形状は、例えば、中心軸AXに対して平行な辺を有する長方形状でもよいし、中心軸AXに対して平行な棒状の形状でもよい。 FIG. 4 is a plan view of the top pad structure 2 included in the packaging apparatus 1 according to the second embodiment. FIG. 5 is a perspective view of the top pad structure 2 included in the packaging apparatus 1 according to the second embodiment. As shown in FIG. 5, in the second embodiment, the inner member 4 has a shape extending parallel to the central axis AX of the outer member 3. In the top pad structure 2 of the second embodiment, regions where the inner member 4 is arranged and regions where the inner member 4 is not arranged exist alternately along the circumferential direction of the outer member 3. do. In other words, the inner member 4 is arranged at a position intersecting a plurality of imaginary lines extending radially from the central axis AX in plan view. In the illustrated example, the inner members 4 are arranged at four locations on the inner periphery of the outer member 3 so that the central angles around the central axis AX are at equal angular intervals of 90 degrees. In the second embodiment, the shape of each inner member 4 may be, for example, a rectangle having sides parallel to the central axis AX, or a rod-like shape parallel to the central axis AX.
 本実施の形態2であれば、前述した実施の形態1の同様の効果が得られる。また、本実施の形態2であれば、内側部材4の構成材料を節約できるので、コスト低減が図れる。 With this second embodiment, the same effects as those of the first embodiment described above can be obtained. Furthermore, according to the second embodiment, since the constituent materials of the inner member 4 can be saved, costs can be reduced.
実施の形態3.
 次に、図6を参照して、実施の形態3について説明するが、前述した実施の形態1との相違点を中心に説明し、共通する説明を簡略化または省略する。また、前述した要素と共通または対応する要素には、同一の符号を付す。
Embodiment 3.
Next, a third embodiment will be described with reference to FIG. 6, focusing on the differences from the first embodiment described above, and common explanations will be simplified or omitted. Further, elements common to or corresponding to those described above are given the same reference numerals.
 図6は、実施の形態3による梱包装置1が備える天部パッド構造体2の部分的な断面側面図である。図6に示すように、本実施の形態では、外側部材3の内面に形成された凹部33に対して、内側部材4の外面に形成された凸部43が嵌合している。これにより、外側部材3に対して内側部材4が固定されている。本実施の形態であれば、接着剤あるいは圧入を用いなくても、外側部材3に対して内側部材4を固定できる。なお、凹部33と凸部43の組が、一つの天部パッド構造体2に対して、複数組、設けられていることが好ましい。それらの複数組は、周方向に沿って並んでいてもよいし、中心軸AXの方向に沿って並んでいてもよい。また、図6の例に代えて、内側部材4の外面に形成された凹部に対して、外側部材3の内面に形成された凸部が嵌合している構成としてもよい。すなわち、外側部材3の内面と内側部材4の外面とのいずれか一方に形成された凹部に対して、外側部材3の内面と内側部材4の外面とのいずれか他方に形成された凸部が嵌合している構成であればよい。 FIG. 6 is a partial cross-sectional side view of the top pad structure 2 included in the packaging device 1 according to the third embodiment. As shown in FIG. 6, in this embodiment, a convex portion 43 formed on the outer surface of the inner member 4 fits into a recess 33 formed on the inner surface of the outer member 3. Thereby, the inner member 4 is fixed to the outer member 3. In this embodiment, the inner member 4 can be fixed to the outer member 3 without using adhesive or press-fitting. Note that it is preferable that a plurality of sets of the concave portion 33 and the convex portion 43 are provided for one top pad structure 2. The plurality of sets may be lined up along the circumferential direction or may be lined up along the direction of the central axis AX. Further, instead of the example shown in FIG. 6, a convex portion formed on the inner surface of the outer member 3 may be fitted into a recess formed on the outer surface of the inner member 4. That is, the convex portion formed on either the inner surface of the outer member 3 or the outer surface of the inner member 4 is larger than the concave portion formed on either the inner surface of the outer member 3 or the outer surface of the inner member 4. Any configuration is sufficient as long as they fit together.
実施の形態4.
 次に、図7を参照して、実施の形態4について説明するが、前述した実施の形態1との相違点を中心に説明し、共通する説明を簡略化または省略する。また、前述した要素と共通または対応する要素には、同一の符号を付す。
Embodiment 4.
Next, with reference to FIG. 7, Embodiment 4 will be described, focusing on the differences from Embodiment 1 described above, and common explanations will be simplified or omitted. Further, elements common to or corresponding to those described above are given the same reference numerals.
 図7は、実施の形態4による梱包装置1のうちの一つの物体90とその上の天部パッド構造体2を示す断面側面図である。図7に示すように、本実施の形態において、内側部材4は、第一層4Aと、第二層4Bと、第三層4Cとが、外側部材3の径方向に積み重なった層構造を有する。第一層4Aの内周に第二層4Bが重なっている。第二層4Bの内周に第三層4Cが重なっている。 FIG. 7 is a cross-sectional side view showing one object 90 of the packaging apparatus 1 and the top pad structure 2 thereon according to the fourth embodiment. As shown in FIG. 7, in this embodiment, the inner member 4 has a layered structure in which a first layer 4A, a second layer 4B, and a third layer 4C are stacked in the radial direction of the outer member 3. . The second layer 4B overlaps the inner periphery of the first layer 4A. A third layer 4C overlaps the inner periphery of the second layer 4B.
 第一層4Aの上端部41Aは、平板12の下面に接する。第二層4Bの上端部41Bは、平板12の下面に接する。第三層4Cの上端部41Cは、平板12の下面に接する。第一層4Aの下端部42Aは、物体90の頂部91の凸曲面に接する。第二層4Bの下端部42Bは、物体90の頂部91の凸曲面に接する。第三層4Cの下端部42Cは、物体90の頂部91の凸曲面に接する。本実施の形態であれば、第一層4A、第二層4B、第三層4Cのそれぞれが、段積みによる垂直荷重を負担することができる。このため、段積みによる垂直荷重に対して、天部パッド構造体2が、より確実に耐えることができる。それゆえ、荷崩れの発生を確実に防止できる。 The upper end portion 41A of the first layer 4A is in contact with the lower surface of the flat plate 12. The upper end portion 41B of the second layer 4B is in contact with the lower surface of the flat plate 12. The upper end portion 41C of the third layer 4C is in contact with the lower surface of the flat plate 12. The lower end 42A of the first layer 4A contacts the convex curved surface of the top 91 of the object 90. The lower end 42B of the second layer 4B contacts the convex curved surface of the top 91 of the object 90. The lower end 42C of the third layer 4C contacts the convex curved surface of the top 91 of the object 90. In this embodiment, each of the first layer 4A, second layer 4B, and third layer 4C can bear the vertical load due to stacking. Therefore, the top pad structure 2 can more reliably withstand the vertical load due to stacking. Therefore, the occurrence of cargo collapse can be reliably prevented.
 第一層4Aの下端部42Aの位置と、第二層4Bの下端部42Bの位置と、第三層4Cの下端部42Cの位置とは、外側部材3の中心に近いほど、高くなる。すなわち、第二層4Bの下端部42Bの位置は、第一層4Aの下端部42Aの位置よりも高い。第三層4Cの下端部42Cの位置は、第二層4Bの下端部42Bの位置よりも高い。これにより、第一層4Aの下端部42Aと、第二層4Bの下端部42Bと、第三層4Cの下端部42Cとが、物体90の頂部91の凸曲面に対して、より確実に接触し、接触面積をより有効に増やすことができる。それゆえ、トラック等による物流輸送時に、擦れをより確実に抑止できる。 The position of the lower end 42A of the first layer 4A, the lower end 42B of the second layer 4B, and the lower end 42C of the third layer 4C become higher as they are closer to the center of the outer member 3. That is, the position of the lower end 42B of the second layer 4B is higher than the position of the lower end 42A of the first layer 4A. The position of the lower end 42C of the third layer 4C is higher than the position of the lower end 42B of the second layer 4B. This ensures that the lower end 42A of the first layer 4A, the lower end 42B of the second layer 4B, and the lower end 42C of the third layer 4C come into contact with the convex curved surface of the top 91 of the object 90 more reliably. However, the contact area can be increased more effectively. Therefore, it is possible to more reliably prevent chafing during physical transportation by truck or the like.
 上述したように、内側部材4は、複数の層が外側部材3の径方向に積み重なった層構造を有していてもよく、複数の層のそれぞれの下端部の位置は、外側部材3の中心に近いほど、高くなっていてもよい。上記の例における内側部材4は、三つの層が積み重なった層構造を有するが、内側部材4の層構造は、二つの層が積み重なったものでもよいし、四つの層またはそれ以上の層が積み重なったものでもよい。 As described above, the inner member 4 may have a layered structure in which a plurality of layers are stacked in the radial direction of the outer member 3, and the lower end of each of the plurality of layers is located at the center of the outer member 3. The closer it is to , the higher it may be. Although the inner member 4 in the above example has a layer structure in which three layers are stacked, the layer structure of the inner member 4 may be one in which two layers are stacked, or four layers or more layers are stacked. It may also be something you have.
実施の形態5.
 次に、図8及び図9を参照して、実施の形態5について説明するが、前述した実施の形態1との相違点を中心に説明し、共通する説明を簡略化または省略する。また、前述した要素と共通または対応する要素には、同一の符号を付す。
Embodiment 5.
Next, a fifth embodiment will be described with reference to FIGS. 8 and 9, but the explanation will focus on the differences from the first embodiment described above, and common explanations will be simplified or omitted. Further, elements common to or corresponding to those described above are given the same reference numerals.
 図8は、実施の形態5による梱包装置1が備える天部パッド構造体2の断面側面図である。図9は、実施の形態5による梱包装置1のうちの一つの物体90とその上の天部パッド構造体2を示す断面側面図である。これらの図に示すように、本実施の形態における天部パッド構造体2の内側部材4は、テーパー形状を有する。すなわち、内側部材4の厚さが、上から下に向かって、漸減している。 FIG. 8 is a cross-sectional side view of the top pad structure 2 included in the packaging apparatus 1 according to the fifth embodiment. FIG. 9 is a cross-sectional side view showing one object 90 of the packaging apparatus 1 and the top pad structure 2 thereon according to the fifth embodiment. As shown in these figures, the inner member 4 of the top pad structure 2 in this embodiment has a tapered shape. That is, the thickness of the inner member 4 gradually decreases from top to bottom.
 図示の例では、内側部材4の上端部41から下端部42までの全域にわたって、内側部材4の厚さが、上から下に向かって、漸減している。このような構成に限らず、上端部41から下端部42までのうちの一部の領域において、内側部材4の厚さが、上から下に向かって、漸減していてもよい。本実施の形態であれば、内側部材4と、物体90の頂部91の凸曲面との接触面積を増やす上で、より有利になる。 In the illustrated example, the thickness of the inner member 4 gradually decreases from top to bottom over the entire area from the upper end 41 to the lower end 42 of the inner member 4. The structure is not limited to this, and the thickness of the inner member 4 may gradually decrease from the top to the bottom in a part of the region from the upper end 41 to the lower end 42. This embodiment is more advantageous in increasing the contact area between the inner member 4 and the convex curved surface of the top portion 91 of the object 90.
 図9に示すように、本実施の形態では、内側部材4の下端部42が、物体90の突出部92にも接する。これにより、段積みによる垂直荷重が作用したときに、内側部材4が負担できる垂直荷重の値が、より大きくなる。その結果、段積みによる垂直荷重に対して、天部パッド構造体2が、より確実に耐えることができる。それゆえ、荷崩れの発生を確実に防止できる。 As shown in FIG. 9, in this embodiment, the lower end 42 of the inner member 4 also contacts the protrusion 92 of the object 90. Thereby, when a vertical load due to stacking is applied, the value of the vertical load that the inner member 4 can bear becomes larger. As a result, the top pad structure 2 can more reliably withstand the vertical load due to stacking. Therefore, the occurrence of cargo collapse can be reliably prevented.
 なお、上述した複数の実施の形態が有する特徴のうち、組み合わせることが可能な二つ以上の特徴を組み合わせて実施してもよい。 Note that among the features of the plurality of embodiments described above, two or more features that can be combined may be combined and implemented.
