Description

本発明は、ワークの運搬等に使用される箱型容器に関するものである。   The present invention relates to a box-type container used for transporting workpieces and the like.

一般に、ワークの運搬等に使用される箱型容器は、底壁構成部と、底壁構成部の外周縁から上方に延出する周壁部とを備えており、上方の開口部から物品を出し入れする構成となっている。また、箱型容器には、内部に収容した所定形状のワークを所定の姿勢で保持可能に構成されるとともに、ワークを収容した状態にある複数の箱型容器を段積みする(スタッキングする)ことができるように構成されたものがある(例えば、特許文献1等参照。)。   In general, a box-type container used for transporting a workpiece has a bottom wall constituent part and a peripheral wall part extending upward from the outer peripheral edge of the bottom wall constituent part, and an article is taken in and out from the upper opening part. It is the composition to do.

(For example, refer patent document 1 etc.).

特開平8−258880号公報JP-A-8-258880

ところで、収容されるワークの形状によっては、箱型容器の内側に形成される収容空間を有効利用することができずに、デッドスペースが比較的大きく形成されてしまう場合がある。この場合、ワークの運搬・保管に箱型容器を使用することによって、所定数のワークを運搬・保管するためのスペースが比較的大きくなってしまうおそれがある。従って、箱型容器の内側の収容空間にほぼ隙間なくワークが収容される場合等に比べ、ワークの運搬効率、保管効率の悪化を招くことが懸念され、特に、箱型容器をスタッキングする場合には、かかる不具合がより顕著なものとなる。   By the way, depending on the shape of the workpiece to be accommodated, the accommodation space formed inside the box-shaped container cannot be effectively used, and the dead space may be formed relatively large. In this case, the use of a box-type container for transporting and storing workpieces may cause a relatively large space for transporting and storing a predetermined number of workpieces. Therefore, there is a concern that the work transportation efficiency and storage efficiency will be deteriorated compared to the case where the work is accommodated in the accommodation space inside the box-shaped container with almost no gap, especially when stacking the box-shaped container. In such a case, such a defect becomes more prominent.

本発明は上記問題点等を解決するためになされたものであって、その目的は、スタッキング状態におけるコンパクト化を図ることのできる箱型容器を提供することにある。   The present invention has been made to solve the above-described problems, and an object thereof is to provide a box-type container that can be made compact in a stacking state.

以下、上記目的等を解決するのに適した各手段につき項分けして説明する。なお、必要に応じて対応する手段に特有の作用効果等を付記する。   In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

手段1.略直線状に延在する直線部と、前記直線部の一端部又はその近傍から交差する方向に突出する突出部とを備えるワークを、前記突出部が下方に突出する姿勢で収容可能に構成されるとともに、
底壁構成部と、前記底壁構成部の外周縁から上方に延出する周壁部とを備え、
同じ向きで上下に重ねることでネスティングが行え、交互に180度回転させて上下に重ねることでスタッキングが行える箱型容器において、
前記ワークの前記突出部を収容可能な突部収容部と、前記突出部が前記突部収容部に収容された状態の前記ワークの前記直線部を支持可能な直線支持部とを備え、
前記突部収容部は、前記底壁構成部から下方に突出する収納用凸部の内側に形成され、
前記ワークが前記直線支持部によって支持されることで、前記直線部が前記突部収容部から遠ざかる方向に向けて下方傾斜するとともに、
前記箱型容器のスタッキング状態において、下側の箱型容器に収容された前記ワークの前記直線部のうち下方傾斜した先端部の上方に、上側の箱型容器の前記収納用凸部が近接配置されるようにしたことを特徴とする箱型容器。
Means 1. A workpiece including a linear portion extending substantially linearly and a protruding portion protruding in a direction intersecting from one end portion of the linear portion or the vicinity thereof is configured to be accommodated in a posture in which the protruding portion protrudes downward. And
A bottom wall constituent part, and a peripheral wall part extending upward from the outer peripheral edge of the bottom wall constituent part,
In a box-type container that can be nested by stacking up and down in the same direction, and can be stacked by rotating 180 degrees alternately and stacking up and down,
A protrusion accommodating portion capable of accommodating the protruding portion of the workpiece; and a linear support portion capable of supporting the linear portion of the workpiece in a state where the protruding portion is accommodated in the protruding portion accommodating portion,
The protrusion accommodating portion is formed on the inner side of the storing convex portion protruding downward from the bottom wall constituting portion,
As the workpiece is supported by the linear support portion, the linear portion is inclined downward in a direction away from the protrusion accommodating portion, and
In the stacking state of the box-shaped container, the storage convex part of the upper box-shaped container is arranged close to the upper part of the linearly inclined portion of the work housed in the lower box-shaped container. A box-type container characterized by being made.

手段1によれば、直線部と、直線部から交差する方向に突出する突出部とを具備するワークは、突出部が下向きに突出するような姿勢で箱型容器に収容される。このため、箱型容器の外周長(外寸)を極力小さくすることができる。さらに、ワークを収容した状態の複数の箱型容器を段積みする(スタッキングする)ことができるように構成されているため、運搬効率や保管効率の向上を図ることができる。   According to the means 1, the workpiece including the straight portion and the protruding portion protruding in the direction intersecting with the straight portion is accommodated in the box-type container in such a posture that the protruding portion protrudes downward. For this reason, the outer peripheral length (outside dimension) of the box-shaped container can be made as small as possible. Furthermore, since it is comprised so that the several box-shaped container in the state which accommodated the workpiece | work can be stacked (stacked), the improvement of conveyance efficiency and storage efficiency can be aimed at.

また、箱型容器には、突出部を収容可能とする突部収容部を形成するべく、底壁構成部から下方に突出する収納用凸部が形成されている。さらに、箱型容器に収容されたワークの直線部は、突出部が設けられていない側の先端部に向けて下方傾斜している。このため、箱型容器をスタッキングさせた場合に、直線部が傾斜していることによって前記先端部の位置が下げられた分だけ、その上方に確保することのできた収容空間に対して、上側の箱型容器の収納用凸部を進入させることができる。従って、複数の箱型容器を上下に極力詰めてスタッキングすることができ、スタッキング状態におけるコンパクト化を図ることができる。   In addition, the box-shaped container is formed with a storage convex portion that protrudes downward from the bottom wall constituting portion so as to form a protrusion accommodating portion that can accommodate the protruding portion. Furthermore, the linear part of the workpiece accommodated in the box-shaped container is inclined downward toward the tip part on the side where the protruding part is not provided. For this reason, when the box-shaped container is stacked, the upper portion of the storage space that can be secured above the amount corresponding to the lowered position of the tip portion due to the inclination of the linear portion is The convex part for storage of a box-shaped container can be made to approach. Accordingly, it is possible to stack a plurality of box-shaped containers as much as possible in the vertical direction, and to achieve compactness in the stacking state.

また、複数の箱型容器を交互に180度回転させて積み重ねることでスタッキングされるため、下側の箱型容器に収容されたワークと、上側の箱型容器に収容されたワークとが、互いに180度回転した向きで、上側の箱型容器の底壁構成部を介して、相対配置されることとなる。このため、スタッキングされた複数の箱型容器からなる積物の荷重の偏りを抑制でき、積物の倒壊等のおそれを防止することができる。   In addition, since the plurality of box-type containers are stacked by alternately rotating 180 degrees, the work housed in the lower box-type container and the work housed in the upper box-type container are mutually connected. In the direction rotated by 180 degrees, they are arranged relative to each other via the bottom wall constituting portion of the upper box-shaped container. For this reason, it is possible to suppress the uneven load of the product composed of the plurality of stacked box-type containers, and to prevent the possibility of collapse of the product.

手段2.前記周壁部を部分的に外周側に膨出させるようにして形成され、スタッキング状態において下側の箱型容器に当接して支持される支脚部を備え、
前記周壁部は相対する一対の側壁部を2組備えるとともに、そのうち1組の相対する一対の前記側壁部において、前記支脚部が相対する位置に形成されていることを特徴とする手段1に記載の箱型容器。

手段2によれば、全ての側壁部に支脚部を設ける場合に比べ、箱型容器の外寸を小さく構成することができる。また、本手段2によれば、相対する側壁部のうち一方の側壁部に形成された支脚部と他方の側壁部に形成された支脚部とが互いに相対する位置に形成されている(1つの側壁部に複数の支脚部が形成される場合には一対の側壁部の支脚部の形成ピッチが同じ)。このため、スタッキング状態において、支脚部が形成された一対の側壁部のうちの一方側と他方側とで支持バランスが比較的大きく異なってしまうといった事態を回避することができ、段積み状態の安定化を図ることができる。   According to the means 2, the outer dimensions of the box-type container can be made smaller than in the case where the supporting leg portions are provided on all the side wall portions. Further, according to the present means 2, the supporting leg portion formed on one of the opposing side wall portions and the supporting leg portion formed on the other side wall portion are formed at positions facing each other (one When a plurality of support legs are formed on the side walls, the formation pitch of the support legs of the pair of side walls is the same). For this reason, in the stacking state, it is possible to avoid a situation in which the support balance is relatively different between one side and the other side of the pair of side wall portions on which the support legs are formed, and the stacked state is stable. Can be achieved.

手段3.前記周壁部は、相対する一対の長辺側側壁部と、前記一対の長辺側側壁部の側縁部間を連結するとともに、前記一対の長辺側側壁部間の距離よりも大きく離間して相対する一対の短辺側側壁部とから構成され、前記支脚部は一対の前記長辺側側壁部に形成されていることを特徴とする手段2に記載の箱型容器。   Means 3.

手段3によれば、長辺側側壁部及び短辺側側壁部のうち横幅が長い方の長辺側側壁部に支脚部が形成されているため、支脚部の形成ピッチを極力大きくすることができ、スタッキング状態の安定化を図ることができる。   According to the means 3, since the supporting leg part is formed on the long side wall part of the longer side of the long side wall part and the short side wall part, the formation pitch of the supporting leg part can be increased as much as possible. It is possible to stabilize the stacking state.

手段4.複数の前記ワークを前記直線部が互いに平行となるようにして横並びで収容可能に構成され、
前記周壁部を構成する側壁部のうち、前記ワークの前記直線部の長手方向に沿って延在する前記側壁部において前記支脚部が形成されるとともに、

手段4によれば、複数のワークの端部に対向する側壁部の内側面には凹凸がほぼ皆無であることから、各ワークがその長手方向において位置ずれしそうになった場合でも、かかる側壁部によって各ワークの端部を安定して支持することができ、位置ずれを確実に防止することができる。また、ワークを収容する際にワークの端部が側壁部に引っ掛かるといった事態を防止することができ、収容作業性を向上させることができる。さらに、直線部に沿って延びる側壁部に関しては、それぞれ1つのワークに隣接するだけなので、当該側壁部においては、隣接する1つのワークのガタツキを防止する構成を設けるだけで済む。このため、ワークのガタツキを防止する構成及び支脚部を設けるスペースを十分に確保することができ、ワークのガタツキを招くことなく、支脚部を設けることができる。   According to the means 4, since there are almost no irregularities on the inner surface of the side wall portion facing the ends of the plurality of workpieces, even if each workpiece is likely to be displaced in the longitudinal direction, the side wall portion Thus, the end portion of each workpiece can be stably supported, and displacement can be reliably prevented. Moreover, the situation that the edge part of a workpiece | work is caught by a side wall part can be prevented when accommodating a workpiece | work, and accommodation workability | operativity can be improved. Furthermore, since the side wall portions extending along the straight line portion are each adjacent to only one workpiece, it is only necessary to provide a configuration that prevents rattling of one adjacent workpiece in the side wall portion. For this reason, the structure which prevents the backlash of a workpiece | work, and the space which provides a support leg part can fully be ensured, and a support leg part can be provided, without causing the backlash of a workpiece | work.

手段5.前記支脚部が形成された前記側壁部には、前記周壁部の外周方向に膨出し、前記箱型容器に収容された前記ワークの前記直線部の側方から当該直線部の下方に手を差し込むことを許容する挿入凹部が形成されていることを特徴とする手段4に記載の箱型容器。   Means 5.

The box-shaped container according to the means 4, wherein an insertion concave portion that allows this is formed.

手段5によれば、挿入凹部が形成されることで、箱型容器に収容されているワークを取出す際に、挿入凹部に手を差し入れて直線部の下側に手を掛けることができる。また、ワークを箱型容器に収容する際に、ワークが直線支持部に支持されるまでワークの下側を手で支持しておくことができる。従って、ワークを箱型容器に収容したり、ワークを箱型容器から取外したりする際の作業性の向上を図ることができる。さらに、支脚部が形成された側壁部に対して挿入凹部が形成されているため、支脚部が形成されていない側壁部に対して別途周壁部の外周側に膨出する挿入凹部を形成する場合に比べ、箱型容器の外寸を極力小さくすることができ、箱型容器の大型化を抑制することができる。   According to the means 5, when the insertion concave portion is formed, when taking out the work housed in the box-shaped container, it is possible to insert a hand into the insertion concave portion and put a hand under the straight portion. Moreover, when accommodating a workpiece | work in a box-type container, the lower side of a workpiece | work can be supported by hand until a workpiece | work is supported by the linear support part. Accordingly, it is possible to improve workability when the work is accommodated in the box-shaped container or the work is removed from the box-shaped container. In addition, since the insertion recess is formed in the side wall portion where the support leg portion is formed, the insertion recess that bulges to the outer peripheral side of the peripheral wall portion separately from the side wall portion where the support leg portion is not formed. In comparison with the above, the outer size of the box-type container can be made as small as possible, and the increase in size of the box-type container can be suppressed.

Then, by superimposing the box-shaped containers 1 in the same direction, the respective supporting leg portions 11 of the upper box-shaped container 1 are accommodated in the respective leg-portion accommodating portions 16 of the lower box-shaped container 1. Thereby, it can nest by stacking the box-shaped container 1 in the same direction as mentioned above.

さて、本実施形態の箱型容器1は、図3に示すように、直線状に延びる直線部22と、直線部22の一端部から直交する方向に突出する突出部23とを備えて略L字状をなすワーク21の運搬等に使用される。図4、図5に示すように、本実施形態では、ワーク21は、突出部23が下方に突出するような姿勢で箱型容器1に収容可能に構成されている。また、本実施形態では、1つの箱型容器1に対して4つのワーク21を収容可能に構成されており、各ワーク21の直線部22が箱型容器1の長手方向に沿って延在するとともに、4つのワーク21の直線部22が互いに平行となるようにして横並びで収容可能に構成されている。さらに、詳しくは後述するが、箱型容器1に収容されたワーク21は、全て同じ姿勢の同じ向きで同じ高さとなるように保持されている。   Now, as shown in FIG. 3, the box-shaped container 1 of the present embodiment includes a linear portion 22 that extends linearly and a protruding portion 23 that protrudes in a direction orthogonal to one end of the linear portion 22. It is used for transporting a workpiece 21 having a character shape. As shown in FIGS. 4 and 5, in the present embodiment, the workpiece 21 is configured to be accommodated in the box-type container 1 in such a posture that the protruding portion 23 protrudes downward. Moreover, in this embodiment, it is comprised so that the four workpiece | work 21 can be accommodated with respect to one box-type container 1, and the linear part 22 of each workpiece | work 21 extends along the longitudinal direction of the box-type container 1. FIG. In addition, the linear portions 22 of the four workpieces 21 are configured to be accommodated side by side so as to be parallel to each other. Furthermore, although mentioned later in detail, the workpiece | work 21 accommodated in the box-type container 1 is hold | maintained so that it may become the same height with the same direction of all the attitude | positions.

本実施形態では、L字状のワーク21を上記のような姿勢で保持するための構成に特徴があるため、以下、かかる構成を中心に説明する。尚、以下の説明では、便宜上、直線部22のうち突出部23が形成された側の端部を「基端部25」と称し、他方の端部を「先端部26」と称する。   In the present embodiment, since the configuration for holding the L-shaped workpiece 21 in the above-described posture is characteristic, the configuration will be mainly described below. In the following description, for convenience, the end of the straight portion 22 on the side where the protruding portion 23 is formed is referred to as a “base end portion 25”, and the other end is referred to as a “tip portion 26”.

図1、図8等に示すように、箱型容器1には、第1短辺側側壁部7aの内側面に沿って設けられ、ワーク21の突出部23を収容可能な突部収容部32と、ワーク21の直線部22を支持可能な直線支持部35とが設けられている。   As shown in FIGS. 1, 8, and the like, the box-shaped container 1 is provided along the inner surface of the first short side wall 7 a and can accommodate the protrusion 23 of the workpiece 21. And the linear support part 35 which can support the linear part 22 of the workpiece | work 21 is provided.

図2に示すように、相対する一対の第1支脚部11aの間には、底壁構成部2から下方に膨出する収納用凸部31が設けられている。そして、図1、図5に示すように、当該収納用凸部31が上方に開口する中空状に構成されていることで、収納用凸部31の内側面により突部収容部32が形成されている。図2に示すように、本実施形態では、収納用凸部31の下端部と支脚部11の下端部との高さ位置が揃うように(仮想の同一平面上に位置するように)構成されている。また、図1に示すように、突部収容部32には、箱型容器1に収容された各ワーク21の突出部23の両側方において、突部収容部32の底面から上方に突出し、ワーク21の突出部23の回動変位を規制する回動規制凸部33が形成されている。これにより、突出部23が下方を向いたワーク21の姿勢が保持されることとなる。   As shown in FIG. 2, a storage convex portion 31 that bulges downward from the bottom wall constituting portion 2 is provided between the pair of opposing first support legs 11 a. As shown in FIG. 1 and FIG. 5, the convex portion 31 is formed by the inner side surface of the convex portion 31 for storage because the convex portion 31 for storage is formed in a hollow shape that opens upward. ing. As shown in FIG. 2, in this embodiment, it is comprised so that the height position of the lower end part of the convex part 31 for storage and the lower end part of the support leg part 11 may align (it is located on the virtual same plane). ing. Further, as shown in FIG. 1, the protrusion accommodating portion 32 protrudes upward from the bottom surface of the protrusion accommodating portion 32 on both sides of the protruding portion 23 of each workpiece 21 accommodated in the box-shaped container 1. A rotation restricting convex portion 33 for restricting the rotational displacement of the protruding portion 23 of 21 is formed. As a result, the posture of the work 21 with the protruding portion 23 facing downward is maintained.

また、直線支持部35は、突部収容部32に隣接して、相対する一対の第2脚受部12bの間に設けられ、直線部22のうち突出部23側の部位(基端部25)を支持する基端側保持部36と、第2短辺側側壁部7bの内側面に隣接して設けられ、直線部22のうちの突出部23が設けられていない側の部位(先端部26)を支持する先端側保持部37とを備えている。   Further, the linear support portion 35 is provided between the pair of opposing second leg receiving portions 12 b adjacent to the protrusion accommodating portion 32, and a portion (base end portion 25) on the protruding portion 23 side of the linear portion 22. ) Supporting the base end side holding portion 36 and the inner side surface of the second short side wall portion 7b, and the portion of the straight portion 22 on the side where the projecting portion 23 is not provided (tip portion) 26) and a front-end side holding portion 37 that supports (26).

図5に示すように、本実施形態では、ワーク21の突出部23が突部収容部32に収容されるとともに、直線部22が直線支持部35によって支持されることにより、直線部22が突部収容部32から遠ざかる方向に向けて下方傾斜するように構成されている。従って、先端部26の上縁部は、基端部25の上縁部よりも下方に位置しており、先端部26から箱型容器1の上縁部(張り出し部4の上面)までの距離は、基端部25から箱型容器1の上縁部までの距離よりも長くなっている。但し、先端側保持部37は突部収容部32の底面よりも上方に位置している。このため、直線部22の下端部となる先端部26の下縁部は、突出部23の下端部よりも上方に位置している。   As shown in FIG. 5, in this embodiment, the projecting portion 23 of the work 21 is accommodated in the projecting portion accommodating portion 32, and the linear portion 22 is supported by the linear support portion 35. It is comprised so that it may incline below toward the direction away from the part accommodating part 32. As shown in FIG. Accordingly, the upper edge portion of the distal end portion 26 is positioned below the upper edge portion of the base end portion 25, and the distance from the distal end portion 26 to the upper edge portion of the box-type container 1 (the upper surface of the overhang portion 4). Is longer than the distance from the base end 25 to the upper edge of the box-shaped container 1. However, the distal end side holding portion 37 is positioned above the bottom surface of the protrusion accommodating portion 32. For this reason, the lower edge part of the front-end | tip part 26 used as the lower end part of the linear part 22 is located above the lower end part of the protrusion part 23. FIG.

尚、直線支持部35のうち直線部22の下側面に当接して支持する部位は、直線部22の長手方向に沿って複数個所存在するが、突部収容部32から離間する部位ほど下方に位置することとなる。例えば、先端側保持部37としては、直線部22の先端部26の端末分を支持する部位と、端末部分から若干離間した部位を支持する部位とが存在し、前者は後者よりも下方に位置する上、直線部22の長手方向においてある程度の長さを有する前者については、その支持面が第2短辺側側壁部7bに向けて下方傾斜している。   Note that there are a plurality of portions of the linear support portion 35 that abut on and support the lower surface of the linear portion 22 along the longitudinal direction of the linear portion 22. Will be located. For example, as the distal end side holding portion 37, there are a portion that supports the terminal portion of the distal end portion 26 of the linear portion 22 and a portion that supports a portion slightly separated from the terminal portion, and the former is positioned below the latter. In addition, the support surface of the former having a certain length in the longitudinal direction of the linear portion 22 is inclined downward toward the second short side wall portion 7b.

また、上記のように、第1脚受部12a及び第2脚受部12bの各支持壁部13の高さ位置は揃っているのではあるが、本実施形態では、直線部22が傾いた状態でワーク21が箱型容器1に収容されるため、各脚受部12a、12bの支持壁部13とワーク21との上下方向における相対位置関係が変化している。すなわち、図5に示すように、ワーク21の直線部22のうち第2脚受部12bに対応する部位は、第2脚受部12bの支持壁部13よりも上方の位置に存在するが、第1脚受部12aに対応する部位は、第1脚受部12aの支持壁部13よりも下方に位置している。これにより、例えば、一対の第1脚受部12aの支持壁部13に対して真っ直ぐな板状体を掛け渡したとしても、かかる板状体がワーク21に圧接しないように構成されている。つまり、上記のように、本実施形態では、一対の第1支脚部11aの間において、第1支脚部11aと同じ長さだけ下方に突出する収納用凸部31が形成されているが、図8に示すように、箱型容器1をスタッキングしても、上側の箱型容器1の収納用凸部31と、下側の箱型容器1のワーク21とが圧接しないように(第1支脚部11aが第1脚受部12aの支持壁部13に確実に当接して支持されるように)なっている。   Further, as described above, although the height positions of the support wall portions 13 of the first leg receiving portion 12a and the second leg receiving portion 12b are aligned, in the present embodiment, the linear portion 22 is inclined. Since the workpiece 21 is accommodated in the box-shaped container 1 in this state, the relative positional relationship in the vertical direction between the support wall portion 13 of each leg receiving portion 12a, 12b and the workpiece 21 is changed. That is, as shown in FIG. 5, the portion corresponding to the second leg receiving portion 12 b of the linear portion 22 of the workpiece 21 exists at a position above the support wall portion 13 of the second leg receiving portion 12 b. The site | part corresponding to the 1st leg receiving part 12a is located below the support wall part 13 of the 1st leg receiving part 12a. Thereby, for example, even if a straight plate-like body is stretched over the support wall portion 13 of the pair of first leg receiving portions 12 a, the plate-like body is configured not to be pressed against the workpiece 21. That is, as described above, in the present embodiment, the storage convex portion 31 that protrudes downward by the same length as the first support leg portion 11a is formed between the pair of first support leg portions 11a. As shown in FIG. 8, even when the box-shaped container 1 is stacked, the storage convex portion 31 of the upper box-shaped container 1 and the work 21 of the lower box-shaped container 1 are not pressed against each other (the first support leg). The portion 11a is supported so as to be surely abutted against and supported by the support wall portion 13 of the first leg receiving portion 12a).

さらに、図1、図7等に示すように、直線支持部35の各保持部36、37には、箱型容器1に収容された各ワーク21の直線部22の両側方において上方に突出し、箱型容器1の短手方向における直線部22の位置ずれを防止するための横ずれ防止凸部38が形成されている。本実施形態では、基端側保持部36の横ずれ防止凸部38のうち、箱型容器1の短手方向中央に設けられた横ずれ防止凸部38aの上面と、脚受部12の支持壁部13の上面とが同じ高さとなるように構成されている。   Furthermore, as shown in FIG. 1, FIG. 7, etc., each holding part 36, 37 of the linear support part 35 protrudes upward on both sides of the linear part 22 of each workpiece 21 accommodated in the box-shaped container 1, A lateral displacement prevention convex portion 38 is formed for preventing the displacement of the straight portion 22 in the lateral direction of the box-shaped container 1. In the present embodiment, among the lateral slip prevention convex portions 38 of the base end side holding portion 36, the upper surface of the lateral slip prevention convex portion 38 a provided at the center in the short direction of the box-shaped container 1 and the support wall portion of the leg receiving portion 12. It is comprised so that the upper surface of 13 may become the same height.

また、図5等に示すように、短辺側側壁部7には、支脚部11や脚受部12が形成されておらず、その内側面はほぼ平坦面となっている。このため、例えば、ワーク21を短辺側側壁部7の内側面に沿わせてスライドさせて箱型容器1に収容することもできる。さらに、基端部25と対向し、突部収容部32の一側面を画定する第1短辺側側壁部7aは、箱型容器1に収容されたワーク21の突出部23の先端部に対して近接又は当接するとともに、先端部26と対向する第2短辺側側壁部7bは、先端部26に対して近接又は当接状態となっている。そして、箱型容器1の長手方向が傾く等した場合、ワーク21の突出部23と突部収容部32の内側面とが当接したり、直線部22の端部と第2短辺側側壁部7bとが当接したりすることで、ワーク21の長手方向における位置ずれが防止されるようになっている。   Further, as shown in FIG. 5 and the like, the short side wall portion 7 is not formed with the supporting leg portion 11 or the leg receiving portion 12, and the inner side surface thereof is substantially flat. For this reason, for example, the workpiece 21 can be slid along the inner side surface of the short side wall portion 7 and accommodated in the box-type container 1. Furthermore, the first short side wall portion 7 a that faces the base end portion 25 and defines one side surface of the protrusion accommodating portion 32 is opposed to the distal end portion of the protruding portion 23 of the work 21 accommodated in the box-shaped container 1. The second short side wall portion 7b facing the tip portion 26 and in close proximity or contact with the tip portion 26 is in the proximity or contact state with the tip portion 26. When the longitudinal direction of the box-shaped container 1 is inclined, the projecting portion 23 of the workpiece 21 and the inner surface of the projecting portion accommodating portion 32 come into contact with each other, or the end portion of the straight portion 22 and the second short side wall portion. 7b abuts, so that the displacement of the workpiece 21 in the longitudinal direction is prevented.

さらに、底壁構成部2のうち直線支持部35を構成する部位、特に、先端側保持部37を構成する部位は、収納用凸部31や支脚部11の下端部よりも上方に位置している。また、底壁構成部2のうち先端側保持部37を構成する部位の下面側には、図2に示すように、相対する一対の第2支脚部11bの丁度中間位置において下方に突出する補助脚部41が下方に突設されている。当該補助脚部41の下端部は、その他の支脚部11の下端部と高さ位置が揃えられており(仮想の同一平面上にあり)いる。すなわち、箱型容器1の先端側保持部37側(第2短辺側側壁部7b側)の部位については、支脚部11及び補助脚部41によって支持される格好となり、設置面に設置した場合、底壁構成部2が橋桁のように設置面から離間した位置で支持されることとなる。   Furthermore, the part which comprises the linear support part 35 among the bottom wall structure parts 2, especially the part which comprises the front end side holding part 37 are located above the convex part 31 for storage, or the lower end part of the support leg part 11. FIG. Yes. Further, on the lower surface side of the portion constituting the distal end side holding portion 37 in the bottom wall constituting portion 2, as shown in FIG. 2, the auxiliary projecting downward just at the intermediate position between the pair of opposing second support legs 11b. The leg part 41 protrudes downward. The lower end portion of the auxiliary leg portion 41 is aligned in height with the lower end portion of the other support leg portion 11 (on the same virtual plane). That is, when the portion of the box-shaped container 1 on the front end holding portion 37 side (second short side wall portion 7b side) is supported by the support leg portion 11 and the auxiliary leg portion 41, it is installed on the installation surface. The bottom wall constituting part 2 is supported at a position separated from the installation surface like a bridge girder.

また、箱型容器1がスタッキングされた場合には、図8に示すように、上側の箱型容器1の支脚部11が下側の箱型容器1の脚受部12に支持されるとともに、図9に示すように、上側の箱型容器1の補助脚部41が、下側の箱型容器1の基端側保持部36の横ずれ防止凸部38(箱型容器1の短手方向中央に設けられた横ずれ防止凸部38a)の上面に当接して支持される。当該補助脚部41により、底壁構成部2の先端側保持部37側の強度を高め、撓み変形等の発生を抑制することができる。さらに、スタッキング時において補助脚部41を支持する横ずれ防止凸部38aの裏面側には補強用のリブ39(図9参照)が設けられおり、当該横ずれ防止凸部38aの耐久性の向上が図られている。尚、基端側保持部36の横ずれ防止凸部38のうち短手方向中央の横ずれ防止凸部38a以外のものは、補助脚部41を支持する等の必要がなく、ワーク21の位置ずれを防止できればよいため、軽量化のために、短手方向中央の横ずれ防止凸部38aよりも高さが低く構成されている。   Further, when the box-shaped container 1 is stacked, as shown in FIG. 8, the support leg portion 11 of the upper box-shaped container 1 is supported by the leg receiving portion 12 of the lower box-shaped container 1, As shown in FIG. 9, the auxiliary leg portion 41 of the upper box-shaped container 1 is provided with a lateral displacement prevention convex portion 38 (the center in the short direction of the box-shaped container 1) of the proximal end holding portion 36 of the lower box-shaped container 1. Is supported in contact with the upper surface of the lateral displacement prevention projection 38a). The auxiliary leg portion 41 can increase the strength of the bottom wall constituting portion 2 on the distal end side holding portion 37 side and suppress the occurrence of bending deformation or the like. Further, a reinforcing rib 39 (see FIG. 9) is provided on the back side of the lateral slip prevention convex portion 38a that supports the auxiliary leg portion 41 during stacking, thereby improving the durability of the lateral slip prevention convex portion 38a. It has been. Of the lateral displacement prevention convex portions 38 of the base end side holding portion 36, those other than the lateral displacement prevention convex portion 38a at the center in the short direction do not need to support the auxiliary leg portion 41, and the work 21 is displaced. In order to reduce the weight, the height is configured to be lower than the lateral shift prevention convex portion 38a at the center in the short direction.

加えて、図1等に示すように、底壁構成部2のうち基端側保持部36と先端側保持部37との間の部位には、上下に貫通する貫通孔42が形成されている。これにより、軽量化及び省資源化が図られる上、ネスティングされた箱型容器1のうち上側の箱型容器1を持ち上げた際に、かかる貫通孔42から上下に重なる箱型容器1間の空間に外気を導入し易くなる。従って、ネスティングした箱型容器1を抜き取る作業を行う際に、上下に重なる箱型容器1間の空間が負圧状態になり、かかる抜き取り作業をスムースに行えないといった事態を防止することができる。   In addition, as shown in FIG. 1 and the like, a through-hole 42 penetrating vertically is formed in a portion of the bottom wall constituting portion 2 between the proximal end side holding portion 36 and the distal end side holding portion 37. . As a result, the weight and resources can be saved, and the space between the box-type containers 1 that are vertically stacked from the through-hole 42 when the upper box-type container 1 is lifted out of the nested box-type containers 1. It becomes easy to introduce the outside air into. Accordingly, when the nested box-shaped container 1 is extracted, the space between the box-shaped containers 1 that are vertically overlapped is in a negative pressure state, and it is possible to prevent such a situation that the extraction operation cannot be performed smoothly.

さらに、図1、図4等に示すように、長辺側側壁部6の長手方向中央部を含む部位には、若干周壁部3の外側に膨出する挿入凹部43が形成されている。これにより、箱型容器1に収容されているワーク21(特に両サイドに収容されているワーク21)を取出す際に、挿入凹部43に手を差し入れて直線部22の下側に手を掛けることができる。さらに、ワーク21を箱型容器1に収容したりする際に、ワーク21が直線支持部35に支持されるまでワーク21の下側を支持しておくことができる。また、一対の長辺側側壁部6のうち一方の挿入凹部43には、周壁部3の外周方向(長辺側側壁部6の厚み方向)に貫通する持ち手孔44が形成されている。つまり、箱型容器1が空の状態では、ワーク21を収容した状態と同様に張り出し部4の下面に手を掛けて持ち運ぶことは勿論のこと、持ち手孔44に手を差し入れて、その上方部位を握って持ち運ぶこともできるようになっている。   Further, as shown in FIGS. 1, 4, etc., an insertion concave portion 43 that slightly bulges outside the peripheral wall portion 3 is formed in a portion including the central portion in the longitudinal direction of the long side wall portion 6. Thereby, when taking out the work 21 accommodated in the box-shaped container 1 (particularly, the work 21 accommodated on both sides), a hand is inserted into the insertion recess 43 and a hand is placed below the straight portion 22. Can do. Furthermore, when the work 21 is accommodated in the box-type container 1, the lower side of the work 21 can be supported until the work 21 is supported by the linear support portion 35. Further, a handle hole 44 penetrating in the outer peripheral direction of the peripheral wall portion 3 (in the thickness direction of the long side wall portion 6) is formed in one insertion concave portion 43 of the pair of long side wall portions 6. That is, when the box-shaped container 1 is empty, it is possible to carry it by placing the hand on the lower surface of the overhanging portion 4 in the same manner as in the state in which the work 21 is accommodated. It is also possible to carry by holding the part.

加えて、図2等に示すように、張り出し部4は、周壁部3の上縁部から外周方向に向けて水平に延出するとともに、先端が下方に屈曲形成されて断面略L字状をなしている。また、張り出し部4の下面側と周壁部3の外面上部とを連結する補強リブ45が周壁部3の周方向において所定間隔で設けられている。尚、張り出し部4の外周縁は基本的に凹凸がなく全体として略長方形状(コーナー部が面取り加工されている)となっている。また、支脚部11、脚受部12、挿入凹部43のいずれにしても、長辺側側壁部6の対応部位を周壁部の外周側に膨出させることで形成されているが、上面視で張り出し部4の外周縁よりも外周側にまでは突出しないように構成されている。   In addition, as shown in FIG. 2 and the like, the overhanging portion 4 extends horizontally from the upper edge portion of the peripheral wall portion 3 toward the outer peripheral direction, and the tip is bent downward to have a substantially L-shaped cross section. There is no. In addition, reinforcing ribs 45 that connect the lower surface side of the overhanging portion 4 and the outer surface upper portion of the peripheral wall portion 3 are provided at predetermined intervals in the circumferential direction of the peripheral wall portion 3. Note that the outer peripheral edge of the overhanging portion 4 basically has no irregularities and has a substantially rectangular shape as a whole (the corner portion is chamfered). Moreover, in any of the support leg part 11, the leg support part 12, and the insertion recessed part 43, it is formed by expanding the corresponding part of the long side wall part 6 to the outer peripheral side of the peripheral wall part. It is comprised so that it may not protrude to the outer peripheral side rather than the outer periphery of the overhang | projection part 4. FIG.

尚、4つの脚受部12の支持壁部13の高さ位置が揃っていることから、箱型容器1をスタッキングしても箱型容器1自体が傾くことはなく、いずれの箱型容器1においても張り出し部4の上面は設置面と平行に延びている。また、支脚部11と支脚部11を支持する脚受部12とが長辺側側壁部6の長手方向中央部を中心として対称位置に設けられているため、スタッキング時において上下に積み重なる箱型容器1の外周縁が大きくずれることはなく、ほぼ一致する。   Since the height positions of the support wall portions 13 of the four leg receiving portions 12 are aligned, the box-shaped container 1 itself does not tilt even when the box-shaped container 1 is stacked, and any box-shaped container 1 The upper surface of the overhanging portion 4 also extends parallel to the installation surface. Further, since the support leg part 11 and the leg receiving part 12 that supports the support leg part 11 are provided at symmetrical positions around the longitudinal center part of the long side wall part 6, the box-type container that is stacked up and down during stacking. The outer peripheral edge of 1 does not greatly deviate and almost coincides.

さて、上記のように構成されてなる箱型容器1をスタッキングした場合、図8等に示すように、上側の箱型容器1の収納用凸部31が、下側の箱型容器1に収容されたワーク21の先端部26の上方において下側の箱型容器1の内側に進入し、先端部26に近接配置された状態とされる。より具体的には、上下方向において、上側の箱型容器1の収納用凸部31の下端部は、下側の箱型容器1に収容されたワーク21の基端部25の上縁部よりも下方に位置している。尚、底壁構成部2のうち直線支持部35を構成する部位の下面は、収納用凸部31の下端部よりも上方に位置しているため、スタッキングされても、下側の箱型容器1に収容されたワーク21(直線部22の基端部25)と、上側の箱型容器1の底壁構成部2とが上下に離間しており、圧接することはない。   Now, when the box-shaped container 1 configured as described above is stacked, the storage convex portion 31 of the upper box-shaped container 1 is accommodated in the lower box-shaped container 1 as shown in FIG. The workpiece 21 enters the inside of the lower box-shaped container 1 above the tip portion 26 of the workpiece 21 and is placed in proximity to the tip portion 26. More specifically, in the vertical direction, the lower end portion of the storage convex portion 31 of the upper box-shaped container 1 is more than the upper edge portion of the base end portion 25 of the work 21 accommodated in the lower box-shaped container 1. Is also located below. In addition, since the lower surface of the site | part which comprises the linear support part 35 among the bottom wall structure parts 2 is located above the lower end part of the convex part 31 for storage, even if it is stacked, a lower box-shaped container The workpiece 21 accommodated in 1 (the base end portion 25 of the straight portion 22) and the bottom wall constituting portion 2 of the upper box-shaped container 1 are separated from each other in the vertical direction, and are not pressed against each other.

以上詳述したように、本実施形態によれば、直線部22と、直線部22から直交する方向に突出する突出部23とを具備するワーク21は、突出部23が下向きに突出するような姿勢で箱型容器1に収容される。このため、箱型容器1の外周長(外寸)を極力小さくすることができる。さらに、ワーク21を収容した状態の複数の箱型容器1を段積みする(スタッキングする)ことができるように構成されているため、運搬効率や保管効率の向上を図ることができる。   As described in detail above, according to the present embodiment, the workpiece 21 including the linear portion 22 and the protruding portion 23 protruding in a direction orthogonal to the linear portion 22 is such that the protruding portion 23 protrudes downward. It is accommodated in the box-type container 1 in the posture. For this reason, the outer peripheral length (outside dimension) of the box-shaped container 1 can be made as small as possible. Furthermore, since it is comprised so that the several box-shaped container 1 of the state in which the workpiece | work 21 was accommodated can be stacked (stacked), the improvement of conveyance efficiency and storage efficiency can be aimed at.

また、箱型容器1には、突出部23を収容可能とする突部収容部32を形成するべく、底壁構成部2から下方に突出する収納用凸部31が形成されている。さらに、箱型容器1に収容されたワーク21の直線部22は、突出部23が設けられていない側の先端部26に向けて下方傾斜している。このため、箱型容器1をスタッキングさせた場合に、直線部22が傾斜していることによって先端部26の位置が下げられた分だけ、その上方に確保することのできた収容空間に対して、上側の箱型容器1の収納用凸部31を進入させることができる。従って、複数の箱型容器1を上下に極力詰めてスタッキングすることができ、スタッキング状態におけるコンパクト化を図ることができる。   Further, in the box-shaped container 1, a storage convex portion 31 protruding downward from the bottom wall constituting portion 2 is formed so as to form a protrusion accommodating portion 32 that can accommodate the protruding portion 23. Furthermore, the linear portion 22 of the workpiece 21 accommodated in the box-type container 1 is inclined downward toward the tip portion 26 on the side where the protruding portion 23 is not provided. For this reason, when the box-shaped container 1 is stacked, with respect to the accommodation space that can be secured above it by the amount by which the position of the distal end portion 26 is lowered due to the inclination of the linear portion 22, The convex part 31 for storage of the upper box-type container 1 can be made to approach. Therefore, a plurality of box-shaped containers 1 can be stacked as much as possible up and down, and the stacking state can be reduced.

また、複数の箱型容器1を交互に180度回転させて積み重ねることでスタッキングされるため、下側の箱型容器1に収容されたワーク21と、上側の箱型容器1に収容されたワーク21とが、互いに180度回転した向きで、上側の箱型容器1の底壁構成部2を介して、相対配置されることとなる。このため、スタッキングされた複数の箱型容器1からなる積物の荷重の偏りを抑制でき、積物の倒壊等のおそれを防止することができる。   In addition, since the plurality of box-shaped containers 1 are alternately stacked by rotating 180 degrees and stacked, the work 21 accommodated in the lower box-shaped container 1 and the work accommodated in the upper box-shaped container 1 are stacked. 21 are arranged relative to each other via the bottom wall constituting portion 2 of the upper box-type container 1 in directions rotated by 180 degrees with respect to each other. For this reason, the bias of the load of the product which consists of the several box-shaped container 1 stacked can be suppressed, and fears, such as collapse of a product, can be prevented.

さらに、支脚部11及び脚受部12は、一対の長辺側側壁部6にのみ設けられ、短辺側側壁部7には設けられないようになっている。このため、例えば、短辺側側壁部7にも支脚部11及び脚受部12を設ける場合に比べ、箱型容器1の外寸を小さく構成することができる。また、相対する長辺側側壁部6のうち、一方の長辺側側壁部6に形成された支脚部11と他方の長辺側側壁部6に形成された支脚部11とが互いに相対する位置に形成されている(各長辺側側壁部6において形成された支脚部11の形成ピッチが同じ)。このため、スタッキング状態において、一方の長辺側側壁部6と他方の長辺側側壁部6とでスタッキング時等の支持バランスが比較的大きく異なってしまうといった事態を回避することができ、段積み状態の安定化を図ることができる。特に、長辺側側壁部6及び短辺側側壁部7のうち横幅(周壁部3の周方向における長さ)が長い方の長辺側側壁部6に支脚部11が形成されているため、支脚部11の形成ピッチを極力大きくすることができ、スタッキング状態の安定化を図ることができる。   Further, the supporting leg portion 11 and the leg receiving portion 12 are provided only on the pair of long side wall portions 6 and are not provided on the short side wall portion 7. For this reason, for example, the outer dimension of the box-shaped container 1 can be made smaller than the case where the supporting leg portion 11 and the leg receiving portion 12 are provided also on the short side wall portion 7. Further, among the opposed long side wall portions 6, positions where the support leg portions 11 formed on one long side wall portion 6 and the support leg portions 11 formed on the other long side wall portion 6 face each other. (The pitches of the support legs 11 formed in each long side wall 6 are the same). For this reason, in the stacking state, it is possible to avoid a situation in which the support balance at the time of stacking and the like is relatively different between the one long side wall 6 and the other long side wall 6. The state can be stabilized. In particular, since the support leg portion 11 is formed on the long side wall portion 6 having the longer lateral width (the length in the circumferential direction of the peripheral wall portion 3) of the long side wall portion 6 and the short side wall portion 7, The formation pitch of the support legs 11 can be increased as much as possible, and the stacking state can be stabilized.

加えて、支脚部11及び脚受部12が設けられていない短辺側側壁部7の内側面は略平坦面となっている。従って、複数のワーク21の端部に対向する短辺側側壁部7の内側面には凹凸がほぼ皆無であることから、各ワーク21がその長手方向において位置ずれしそうになった場合でも、かかる短辺側側壁部7の内側面によって各ワーク21の端部を安定して支持することができ、位置ずれを防止することができる。また、ワーク21を収容する際にワーク21の端部が短辺側側壁部7に引っ掛かるといった事態を防止することができ、収容作業性を向上させることができる。さらに、直線部22に沿って延びる長辺側側壁部6に関しては、それぞれ1つのワーク21に隣接するだけなので、長辺側側壁部6においては、隣接する1つのワーク21のガタツキを防止する構成を設けるだけで済む。このため、ワーク21のガタツキを防止する構成及び支脚部11を設けるスペースを十分に確保することができ、ワーク21のガタツキを招くことなく、支脚部11を設けることができる。   In addition, the inner side surface of the short side wall portion 7 where the support leg portion 11 and the leg receiving portion 12 are not provided is a substantially flat surface. Therefore, since there is almost no unevenness on the inner side surface of the short side wall 7 facing the ends of the plurality of workpieces 21, even if each workpiece 21 is likely to be displaced in the longitudinal direction, The end portion of each workpiece 21 can be stably supported by the inner side surface of the short side wall portion 7, and displacement can be prevented. Moreover, the situation where the edge part of the workpiece | work 21 is caught by the short side wall part 7 when accommodating the workpiece | work 21 can be prevented, and accommodation workability | operativity can be improved. Further, since the long side wall 6 extending along the straight portion 22 is only adjacent to one workpiece 21, the long side wall 6 is configured to prevent rattling of one adjacent workpiece 21. All you need to do is provide. For this reason, the structure which prevents the play of the workpiece | work 21 and the space which provides the support leg part 11 can be ensured enough, and the support leg part 11 can be provided, without causing the play of the work 21.

また、長辺側側壁部6の長手方向中央部を含む部位には、周壁部3の外周側に膨出し、長辺側側壁部6に隣接して設置されているワーク21の側方からかかるワーク21の下方に手を差し入れることを可能とする挿入凹部43が形成されている。このように、挿入凹部43が形成されることで、箱型容器1に収容されているワーク21を取出す際に、挿入凹部43に手を差し入れて直線部22の下側に手を掛けることができる。また、ワーク21を箱型容器1に収容する際に、ワーク21が直線支持部35に支持されるまでワーク21の下側を手で支持しておくことができる。従って、ワーク21を箱型容器1に収容したり、ワーク21を箱型容器1から取外したりする際の作業性の向上を図ることができる。さらに、支脚部11が形成された長辺側側壁部6に対して挿入凹部43が形成されているため、支脚部11が形成されていない短辺側側壁部7に対して別途周壁部3の外周側に膨出する挿入凹部43を形成する場合に比べ、箱型容器1の外寸を極力小さくすることができ、箱型容器1の大型化を抑制することができる。   Moreover, it swells to the outer peripheral side of the surrounding wall part 3 in the site | part containing the longitudinal direction center part of the long side wall part 6, and it starts from the side of the workpiece | work 21 installed adjacent to the long side wall part 6. An insertion recess 43 that allows a hand to be inserted under the workpiece 21 is formed. Thus, when the insertion recess 43 is formed, when taking out the workpiece 21 accommodated in the box-type container 1, it is possible to insert a hand into the insertion recess 43 and put a hand under the straight portion 22. it can. Further, when the work 21 is accommodated in the box-type container 1, the lower side of the work 21 can be supported by hand until the work 21 is supported by the linear support portion 35. Therefore, it is possible to improve workability when the work 21 is accommodated in the box-type container 1 or when the work 21 is detached from the box-type container 1. Furthermore, since the insertion recess 43 is formed in the long side wall portion 6 in which the support leg portion 11 is formed, the peripheral wall portion 3 is separately provided in the short side wall portion 7 in which the support leg portion 11 is not formed. Compared with the case where the insertion concave portion 43 that bulges to the outer peripheral side is formed, the outer size of the box-shaped container 1 can be made as small as possible, and an increase in the size of the box-shaped container 1 can be suppressed.
