Description

本発明は、底面が正方形の箱形をなし、その底面に転がり軸受の一端面を重ねて収容可能な軸受搬送用コンテナに関する。 The present invention relates to a bearing transport container that has a box shape with a square bottom surface and can be accommodated by stacking one end surface of a rolling bearing on the bottom surface.

従来、この種の軸受搬送用コンテナとして、底面全体に複数の位置決め嵌合孔を設け、任意の位置決め嵌合孔に嵌合した４つの横ずれ規制部品を転がり軸受の外周面に宛がうことで転がり軸受の横ずれを防止する構成のコンテナが知られている。また、これと同様の横ずれ防止機構を有したコンテナとして、植木鉢やロール等の略円柱形状の荷物を収容可能なものが知られている（例えば、特許文献１参照）。 Conventionally, as this type of bearing transport container, a plurality of positioning fitting holes are provided on the entire bottom surface, and four lateral deviation regulating parts fitted in arbitrary positioning fitting holes are applied to the outer peripheral surface of the rolling bearing. There is known a container having a configuration for preventing a lateral displacement of a rolling bearing. Further, as a container having a lateral shift prevention mechanism similar to this, a container that can accommodate a substantially cylindrical load such as a flower pot or a roll is known (for example, see Patent Document 1).

特開２００３−１２８１５４号公報（第４図、第５図）Japanese Patent Laid-Open No. 2003-128154 (FIGS. 4 and 5)

しかしながら、上記した従来の軸受搬送用コンテナでは、転がり軸受の外周面を周方向で４等分する位置に４つの横ずれ規制部品を配置することが困難であった。このため、搬送中にコンテナ内で横Ｇを受けた転がり軸受が比較的間隔が広くなった１対の横ずれ規制部品の間に割り込むように押し付けられることで、一部の横ずれ規制部品が多大な負荷を受けて変形し、コンテナ内で転がり軸受が不安定になる事態が起こり得た。 However, in the conventional bearing transport container described above, it has been difficult to arrange the four lateral deviation restricting parts at a position where the outer peripheral surface of the rolling bearing is divided into four equal parts in the circumferential direction. For this reason, a part of the lateral deviation regulating parts is enormous because the rolling bearing that has received the lateral G in the container during conveyance is pressed so as to interrupt between a pair of lateral deviation regulating parts having a relatively large interval. It could deform under the load and cause the rolling bearing to become unstable in the container.

本発明は、上記事情に鑑みてなされたもので、安定して転がり軸受を搬送可能な軸受搬送用コンテナの提供を目的とする。 This invention is made | formed in view of the said situation, and aims at provision of the container for bearing conveyance which can convey a rolling bearing stably.

A plurality of engaging leg pieces are provided on each part and communicated by a portal wall, and one end of the positioning protrusion is characterized in that it is covered with a rolling bearing from above .

請求項３の発明は、請求項２に記載の軸受搬送用コンテナにおいて、ベース板の一端部側の係合脚片と他端部側で係合脚片との側縁部の上部同士の間を平板状の脚片連絡壁で連絡し、それら脚片連絡壁で連絡された係合脚片同士の間に複数の位置決突片が係合するところに特徴を有する。 According to a third aspect of the present invention, in the container for container transfer according to the second aspect, a flat plate is provided between the engaging leg piece on one end side of the base plate and the upper portion of the side edge portion of the engaging leg piece on the other end side.

Moreover, since the engaging the base portion of the four lateral regulatory components in a horizontal positioning grooves extending diagonally of the bottom surface is received in an arbitrary positioning protrusion, upward from the base portion of it et lateral displacement restricting parts The positioning protrusion protruding in the direction can be easily assigned to a position where the inner peripheral surface or outer peripheral surface of the rolling bearing is divided into four equal parts. As a result, it is possible to prevent a part of the lateral displacement regulating parts from being deformed due to a great load as in the prior art, and to stably transport the rolling bearing.

また、請求項２の軸受搬送用コンテナでは、受容した転がり軸受が各横ずれ規制部品のベース部の一端部を上方から覆い、ベース部を水平位置決溝における任意の位置に容易に抜け止めすることができる。 Further, in the bearing carrying container according to claim 2, receiving the rolling bearing is not covering one end of the base portion of the lateral shift restricting part from above, it is fastened easily escape in any position of the base portion in the horizontal position Kemmizo be able to.

A pair of groove front walls 13V and 13V extend from the side wall body 13S so as to approach each other at the intersections between the groove step walls 21B and 21B on both sides and the side wall body 13S. As shown in FIG. 8B, these groove front walls 13V and 13V extend over the entire vertical direction of the side wall groove 20 and are substantially parallel to the groove back wall 21A. By these groove front walls 13V and 13V, the side wall groove 20 has a structure in which the back side is wider on both sides than the side surface groove opening 20B opened to the inner surface of the side wall 13.

図８（Ａ）に示すように、溝奥部壁２１Ａのうち溝前部壁１３Ｖ，１３Ｖと対向する両側部には、複数の位置決係合孔２２が貫通形成されている。位置決係合孔２２は、横長長方形のスリット状になっており、一定の間隔ｂ（図１８参照）を空けて例えば８つずつ上下方向に並べられかつ左右対称に配置されている。 As shown in FIG. 8A, a plurality of positioning engagement holes 22 are formed through both sides of the groove back wall 21A facing the groove front walls 13V and 13V. The positioning engagement holes 22 are formed in a horizontally-long rectangular slit shape, and are arranged vertically, for example, eight by eight at regular intervals b (see FIG. 18).

側壁溝２０のうち上方に開放した端面溝開口２０Ａの開口縁には、上面フランジ１３Ｘのうち溝奥部壁２１Ａより外側を段付き状に陥没させて開口段差部１３Ｄが形成されている。また、矩形膨出部２１の外面には、その上端寄り位置に補強リブ１３Ｌの一部である横リブ１３Ｙが横切っている。さらに、矩形膨出部２１の外面上部における幅方向の中央には、縦リブ１３Ｚが形成されて横リブ１３Ｙと上面フランジ１３Ｘとの間を連絡している。 An opening step portion 13D is formed at the opening edge of the end surface groove opening 20A opened upward in the side wall groove 20 by recessing the outside of the groove inner wall 21A of the upper surface flange 13X in a stepped shape. Further, a lateral rib 13Y, which is a part of the reinforcing rib 13L, crosses the outer surface of the rectangular bulging portion 21 at a position near its upper end. Further, a longitudinal rib 13Z is formed at the center in the width direction at the upper part of the outer surface of the rectangular bulging portion 21, and communicates between the lateral rib 13Y and the upper surface flange 13X.

図２に示すように、コンテナ１０の底壁１２の内面の中央には、円形陥没部１５Ｃが形成されると共に、円形陥没部１５Ｃから放射線状に複数の軸受取出用溝１５Ａと複数の水平位置決溝１５Ｂとが延びている。水平位置決溝１５Ｂは、円形陥没部１５Ｃから四方に延びた底面１２Ａの対角線に沿う位置に配置されている。一方、軸受取出用溝１５Ａは、隣り合った水平位置決溝１５Ｂ，１５Ｂ同士の中央に配置されている。 As shown in FIG. 2, a circular depression 15C is formed at the center of the inner surface of the bottom wall 12 of the container 10, and a plurality of bearing extraction grooves 15A and a plurality of horizontal positions are formed radially from the circular depression 15C. The determination groove 15B extends. The horizontal positioning groove 15B is disposed at a position along the diagonal line of the bottom surface 12A extending in four directions from the circular depression 15C. On the other hand, the bearing extraction groove 15A is disposed at the center between the adjacent horizontal positioning grooves 15B and 15B.

図５に示すように、各水平位置決溝１５Ｂは、底壁１２の内面を段付き状に陥没させた構造をなし、その内の長手方向に沿って複数の位置決突片１６が等間隔に並んでいる。各位置決突片１６は、水平位置決溝１５Ｂの底面と両内側面とに直交した状態に連結されている。また、図７に示すように、位置決突片１６の上端縁全体は、底壁１２の上面より下方に位置している。さらに、図５に示すように、位置決突片１６の上端縁の両側端部には、切欠部１６Ｋが形成されている。なお、各水平位置決溝１５Ｂのうち円形陥没部１５Ｃから離れた端部には、切欠部１６Ｋを有しない終端突片１６Ｂが備えられている。 As shown in FIG. 5, each horizontal positioning groove 15 B has a structure in which the inner surface of the bottom wall 12 is depressed in a stepped shape, and a plurality of positioning protrusions 16 are formed along the longitudinal direction of the horizontal positioning groove 15 B. They are lined up at intervals. Each positioning protrusion 16 is connected in a state orthogonal to the bottom surface and both inner side surfaces of the horizontal positioning groove 15B. Further, as shown in FIG. 7, the entire upper end edge of the positioning protrusion 16 is positioned below the upper surface of the bottom wall 12. Further, as shown in FIG. 5, notches 16 K are formed at both end portions of the upper end edge of the positioning protrusion 16. In addition, the terminal protrusion 16B which does not have the notch part 16K is provided in the edge part which left | separated from the circular recessed part 15C among each horizontal positioning groove 15B.

一方、軸受取出用溝１５Ａは、水平位置決溝１５Ｂから位置決突片１６及び終端突片１６Ｂを排除した構造になっている。これにより、コンテナ１０内から転がり軸受Ｗを取り出す際には、円形陥没部１５Ｃから軸受取出用溝１５Ａに工具又は指を挿入して容易に転がり軸受Ｗをコンテナ１０から取り出すことができる。 On the other hand, the bearing extraction groove 15A has a structure in which the positioning protrusion 16 and the terminal protrusion 16B are excluded from the horizontal positioning groove 15B. Thereby, when taking out the rolling bearing W from the container 10, the rolling bearing W can be easily taken out from the container 10 by inserting a tool or a finger into the bearing taking-out groove 15A from the circular depression 15C.

図２に示すように、底面１２Ａのうち各水平位置決溝１５Ｂの両側縁部には、複数の外径表示目印９０が付されている。各外径表示目印９０は、図１９に拡大して示されており、例えば、底面１２Ａの図心からの距離の２倍の長さを転がり軸受Ｗの直径として表示した数値部９０Ａとその数値部９０Ａから水平位置決溝１５Ｂに向かって延びた位置合わせライン９０Ｂとから構成されている。 As shown in FIG. 2, the side edge portions of the horizontal position Kemmizo 15B of the bottom surface 12A, an outer diameter of the display mark 90 of the multiple is attached. Each outer diameter display mark 90 is shown in an enlarged manner in FIG. 19. For example, a numerical value portion 90 A in which a length twice the distance from the centroid of the bottom surface 12 A is displayed as the diameter of the rolling bearing W and its numerical value portion. The alignment line 90B extends from 90A toward the horizontal positioning groove 15B.

The portion 42 may be inserted into the side groove opening 20B from the upper end. And the slide part 43 is arrange | positioned in arbitrary height in the side wall groove | channel 20, and the slide part 43 is moved to the uneven | corrugated engagement position of 21 A of groove | channel back walls of the side wall groove 20, and the positioning engagement protrusion 44 group Is engaged with a part of the positioning engagement hole 22 group. In this state, when the spacer component 60 described below is inserted into the gap between the groove front wall 13V and the slide part 43, the slide part 43 moves from the concave / convex engagement position to the engagement release position on the groove front wall 13V side. It becomes impossible and the attachment to the side wall groove | channel 20 of the jumping control part 40 is completed. And the workpiece control part 41 is addressed from upper direction with respect to the rolling bearing W mounted on the bottom wall 12 of the container 10, and the upward jumping of the rolling bearing W can be controlled.

ここで、本実施形態では、跳上規制部品４０を第１姿勢にするか第２姿勢にするかによって、ワーク規制部４１の下面の高さ位置（図１８のｘ，ｙ参照）が異なる。具体的には、図１８に示すように、跳上規制部品４０を第１姿勢にしたときのワーク規制部４１の下面（ワーク規制プレート４１Ａのうち格子壁４１Ｃと反対側の面）を第１ワーク押え面４１Ｘとし、跳上規制部品４０を第２姿勢にしたときのワーク規制部４１の下面（格子壁４１Ｃのうちワーク規制プレート４１Ａと反対側の面）を第２ワーク押え面４１Ｙとし、さらに、位置決係合孔２２，２２同士の上下の間隔ｂを１ピッチと呼ぶこととすると、跳上規制部品４０を第２姿勢にした状態では、図１８の実線で示すように、ワーク規制部４１の第２ワーク押え面４１Ｙは、側壁溝２０の内側下面と同じ第１位置ｙ１と、その第１位置ｙ１より１ピッチ上方の第２位置ｙ２、第１位置ｙ１より２ピッチ上方の第３位置ｙ３、第１位置ｙ１より３ピッチ上方の第４位置ｙ４とに位置決めすることができる。 Here, in the present embodiment, the height position (see x and y in FIG. 18) of the lower surface of the work restricting portion 41 varies depending on whether the jumping restricting component 40 is in the first posture or the second posture. Specifically, as shown in FIG. 18, the lower surface of the work restricting portion 41 (the surface of the work restricting plate 41 A opposite to the lattice wall 41 C) when the jumping restricting component 40 is in the first posture is the first. The work holding surface 41X is used, and the lower surface of the work restricting portion 41 (the surface of the lattice wall 41C opposite to the work restricting plate 41A) when the jumping restricting component 40 is in the second posture is used as the second work holding surface 41Y. Furthermore, assuming that the vertical distance b between the positioning engagement holes 22 and 22 is referred to as one pitch, as shown by a solid line in FIG. The second work pressing surface 41Y of the portion 41 has the same first position y1 as the inner lower surface of the side wall groove 20, a second position y2 that is one pitch above the first position y1, and a second position y2 that is two pitches above the first position y1. 3 position y3, 1st position y1 3 can be positioned on the pitch fourth position above y4.

A first position x1 that is 1.5 pitches above the first position y1), a second position x2 that is one pitch above the first position x1, and a third position x3 that is two pitches above the first position x1. The fourth position x4 can be positioned three pitches higher than the first position x1. That is, in the present embodiment, the lower surface of the work restricting portion 41 described above is moved from the second position y2 that is one pitch above the inner lower surface of the side wall groove 20 to the third position x3 that is 3.5 pitches above the inner lower surface of the side wall groove 20. In the range up to, it is possible to position by changing in 0.5 pitch increments.

なお、上記のように跳上規制部品４０を第１姿勢にするか第２姿勢にするかによって、ワーク規制部４１の下面の高さ位置が異なるようにするために、本実施形態の跳上規制部品４０は、第１姿勢としたときに例えば最下部となる位置決係合突起４４の下面からワーク規制部４１の下面までの距離と、第２姿勢としたときに最下部となる位置決係合突起４４の下面からワーク規制部４１の下面までの距離との差を、位置決係合孔２２，２２同士の上下の間隔ｂの整数倍からずらした値（例えば、間隔ｂの１．５倍）になるように構成されている。 In addition, in order to make the height position of the lower surface of the workpiece | work control part 41 differ by whether it makes the 1st attitude | position or the 2nd attitude | position as mentioned above, the jump of this embodiment For example, when the restricting component 40 is in the first posture, for example, the distance from the lower surface of the positioning engagement protrusion 44 that is the lowermost portion to the lower surface of the work restricting portion 41 and the position that is the lowermost portion when the second posture is set. A value obtained by shifting the difference between the distance from the lower surface of the engagement protrusion 44 to the lower surface of the work restricting portion 41 from an integral multiple of the vertical distance b between the positioning engagement holes 22 and 22 (for example, 1 of the distance b). 5 times).

次に、スペーサ部品６０の構成について説明する。図１０に示すように、スペーサ部品６０は側壁溝２０の端面溝開口２０Ａを閉塞可能な長方形の板蓋６１を備え、その板蓋６１の一方の長辺における両端部から１対のスライド脚部６２，６２が垂下する一方、他方の長辺における中央部から係止突片６３が垂下した構造になっている。 Next, the configuration of the spacer component 60 will be described. As shown in FIG. 10, the spacer component 60 includes a rectangular plate lid 61 capable of closing the end surface groove opening 20 A of the side wall groove 20, and a pair of slide legs from both ends on one long side of the plate lid 61. While 62 and 62 hang down, it has the structure where the latching protrusion 63 hangs down from the center part in the other long side.

板蓋６１は、図１４に示すように、係止突片６３側の端部が上面フランジ１３Ｘにおける開口段差部１３Ｄに収まり、スライド脚部６２側の端部が端面溝開口２０Ａの内側に嵌って端面溝開口２０Ａを閉塞する。この状態で板蓋６１の上面は、上面フランジ１３Ｘ全体の上面より若干下方に位置する。 As shown in FIG. 14, the plate lid 61 has an end on the side of the locking protrusion 63 fitted in the opening step portion 13D of the upper surface flange 13X, and an end on the slide leg 62 side fitted inside the end surface groove opening 20A. Thus, the end surface groove opening 20A is closed. In this state, the upper surface of the plate lid 61 is located slightly below the upper surface of the entire upper surface flange 13X.

図１０に示すように、各スライド脚部６２は、上下方向に延びた帯板状の両側縁部から係止突片６３側に１対の突条６２Ａ，６２Ａを突出させた構造になっている。また、各スライド脚部６２と板蓋６１における短辺側の外縁部との間は四角形の補強リブ６１Ｌにて連結されている。そして、図１５及び図１６に示すように、板蓋６１が端面溝開口２０Ａを閉塞した状態で、溝前部壁１３Ｖと溝奥部壁２１Ａとの間に補強リブ６１Ｌとスライド脚部６２の基端部とが嵌り、溝前部壁１３Ｖと溝奥部壁２１Ａとの対向方向でスペーサ部品６０を位置決めする。また、スライド脚部６２は側壁溝２０の奥部まで挿入された状態で、スライド脚部６２の先端は、側壁溝２０の下面に隣接又は接触した状態になる。 As shown in FIG. 10, each slide leg 62 has a structure in which a pair of ridges 62A and 62A protrude from the both side edges of the strip plate extending in the vertical direction toward the locking projection 63. Yes. Each slide leg 62 and the outer edge on the short side of the plate lid 61 are connected by a square reinforcing rib 61L. As shown in FIGS. 15 and 16, with the plate lid 61 closing the end face groove opening 20A, the reinforcing rib 61L and the slide leg 62 are interposed between the groove front wall 13V and the groove rear wall 21A. The base end portion is fitted, and the spacer component 60 is positioned in the facing direction between the groove front wall 13V and the groove back wall 21A. In addition, the slide leg 62 is inserted to the back of the side wall groove 20, and the tip of the slide leg 62 is adjacent to or in contact with the lower surface of the side wall groove 20.

図１０に示すように、係止突片６３は、板蓋６１から下方の直角曲げされた突片構造をなし、上下より左右の幅が大きくなっている。また、係止突片６３は、板蓋６１側の縁部に沿って延びたスリット６３Ｓを幅方向の中央に備え、係止突片６３の裏面には、スリット６３Ｓより下方に１対の係止突起６４，６４を横並びにして備えている。そして、スライド脚部６２を側壁溝２０に上方から挿入していく過程で、係止突起６４，６４における下向きの斜面が上面フランジ１３Ｘの外縁部に摺接して係止突片６３が外側に撓み、図１４に示すように、板蓋６１が端面溝開口２０Ａを閉塞した状態で、係止突起６４，６４が上面フランジ１３Ｘを乗り越えて、縦リブ１３Ｚの両側で上面フランジ１３Ｘの下面に係止して、スペーサ部品６０を側壁溝２０に抜け止めする。 As shown in FIG. 10, the locking protruding piece 63 has a protruding piece structure bent at a right angle downward from the plate lid 61, and has a lateral width larger than the upper and lower sides. The locking projection 63 includes a slit 63S extending along the edge on the side of the plate lid 61 at the center in the width direction, and a pair of engagements on the back surface of the locking projection 63 below the slit 63S. the retaining projection 64,6 4 comprises in the side-by-side. Then, in the process of inserting the slide leg 62 into the side wall groove 20 from above, the downward slope of the locking projections 64, 64 is in sliding contact with the outer edge portion of the upper surface flange 13X, and the locking projection 63 is bent outward. As shown in FIG. 14, with the plate lid 61 closing the end face groove opening 20A, the locking protrusions 64, 64 get over the upper surface flange 13X and are locked to the lower surface of the upper surface flange 13X on both sides of the vertical rib 13Z. Then, the spacer component 60 is prevented from coming off in the side wall groove 20.

本実施形態のコンテナ１０に関する説明は以上である。次に、本実施形態の作用効果について説明する。転がり軸受Ｗは、以下のようにしてコンテナ１０内に固定される。まず、転がり軸受Ｗをコンテナ１０に収容する前に４つの横ずれ規制部品３０を水平位置決溝１５Ｂに装着する。そのためには、コンテナ１０に収容する予定の転がり軸受Ｗの外径に対応した外径表示目印９０の位置合わせライン９０Ｂに、各横ずれ規制部品３０の位置合わせ目印９１，９１を一致させてベース部３２を水平位置決溝１５Ｂ内に上方から嵌合する。すると、図７に示すように、門形壁３４の上端部及び脚片連絡壁３７が位置決突片１６の切欠部１６Ｋ（図５参照）内に収まると共に、位置決突片１６が門形壁３４のスリット３５及び突片受容隙間３６に収まり、さらに、各係合脚片３３が隣り合った位置決突片１６，１６の間に収まる。また、位置決突片１６の上端部は、ベース板３２Ａの下面に突き当てられる。これらにより、ベース部３２が水平位置決溝１５Ｂ内で位置決めされる。そして、各横ずれ規制部品３０のベース部３２の上面が、底壁１２の上面より若干低い位置に位置し、各横ずれ規制部品３０の位置決突部３１が、底壁１２の上面より上方に突出した状態になる。 The description regarding the container 10 of the present embodiment has been described above. Next, the effect of this embodiment is demonstrated. The rolling bearing W is fixed in the container 10 as follows. First, before the rolling bearing W is accommodated in the container 10, the four lateral displacement restricting parts 30 are mounted in the horizontal positioning groove 15B. For this purpose, the alignment marks 91 and 91 of the lateral deviation restricting parts 30 are aligned with the alignment line 90B of the outer diameter display mark 90 corresponding to the outer diameter of the rolling bearing W that is to be accommodated in the container 10. 32 is fitted into the horizontal positioning groove 15B from above. Then, as shown in FIG. 7, the upper end portion of the portal wall 34 and the leg piece connecting wall 37 are accommodated in the notch 16 K (see FIG. 5) of the positioning protrusion 16, and the positioning protrusion 16 is the gate shape. It fits in the slit 35 and the protrusion receiving space 36 of the wall 34, and each engagement leg piece 33 is also placed between the adjacent positioning protrusions 16 and 16. Further, the upper end portion of the positioning protrusion 16 is abutted against the lower surface of the base plate 32A. Accordingly, the base portion 32 is positioned in the horizontal positioning groove 15B. Then, the upper surface of the base portion 32 of each lateral displacement regulating component 30 is positioned slightly lower than the upper surface of the bottom wall 12, and the positioning protrusion 31 of each lateral displacement regulating component 30 projects upward from the upper surface of the bottom wall 12. It will be in the state.

この状態で、４つの横ずれ規制部品３０の位置決突部３１群の内側に転がり軸受Ｗを寝かせた状態で収容する。このとき、誤って転がり軸受Ｗが位置決突部３１の上端部に当接しても、位置決突部３１の上端部は半球状になっているので、転がり軸受Ｗが傷付くことが防がれる。また、転がり軸受Ｗが正規の収容位置から多少ずれていても、転がり軸受Ｗの外縁部が位置決突部３１の上端部の球面に摺接して転がり軸受Ｗが正規の収容位置に案内される。そして、転がり軸受Ｗの一端面が底面１２Ａに重なるように載置され、各横ずれ規制部品３０におけるベース部３２のうち位置決突部３１より底面１２Ａの中央側に位置した部分が転がり軸受Ｗによって上方から覆われる。これによりベース部３２の水平位置決溝１５Ｂにおける抜け止めが図られる。そして、位置決突部３１群が転がり軸受Ｗの外周面を４等分する位置にそれぞれ宛われて、転がり軸受Ｗの四方への横ずれが防がれる。 In this state, the rolling bearing W is accommodated in a state where it is laid inside the positioning protrusions 31 of the four lateral displacement regulating components 30. At this time, even if the rolling bearing W accidentally contacts the upper end of the positioning protrusion 31, the upper end of the positioning protrusion 31 is hemispherical, so that the rolling bearing W is prevented from being damaged. It is. Further, even if the rolling bearing W is slightly deviated from the regular accommodation position, the outer edge portion of the rolling bearing W is in sliding contact with the spherical surface of the upper end portion of the positioning protrusion 31 so that the rolling bearing W is guided to the regular accommodation position. . And the one end surface of the rolling bearing W is mounted so that it may overlap with the bottom face 12A, and the part located in the center side of the bottom face 12A from the positioning protrusion 31 among the base parts 32 in each lateral deviation control component 30 by the rolling bearing W Covered from above. As a result, the horizontal positioning groove 15B of the base portion 32 is prevented from coming off. Then, the positioning protrusions 31 are respectively assigned to positions at which the outer peripheral surface of the rolling bearing W is divided into four equal parts, and the lateral displacement of the rolling bearing W in all directions is prevented.

次いで、図１１から図１２に示すように、例えば、跳上規制部品４０を第１姿勢にしてスライド部４３を端面溝開口２０Ａから側壁溝２０に挿入し、ワーク規制部４１を転がり軸受Ｗに当接させた位置で、図１３に示すように跳上規制部品４０を側壁溝２０の溝奥部壁２１Ａ側の凹凸係合位置に移動して、位置決係合突起４４を位置決係合孔２２に凹凸係合させる。このとき、位置決係合突起４４の溝奥部壁２１Ａ側に押し付けても位置決係合孔２２に凹凸係合できない場合には、側壁溝２０からスライド部４３を一度抜いて、図１７に示すように反転させてから側壁溝２０に挿入し、ワーク規制部４１を転がり軸受Ｗに当接させた位置で位置決係合突起４４を位置決係合孔２２に凹凸係合させる。 Next, as shown in FIGS. 11 to 12, for example, the jump restricting part 40 is set to the first posture, the slide part 43 is inserted into the side wall groove 20 from the end face groove opening 20 A, and the work restricting part 41 is set to the rolling bearing W. At the abutted position, the jumping restricting component 40 is moved to the concave / convex engaging position on the groove rear wall 21A side of the side wall groove 20 as shown in FIG. The concave and convex portions are engaged with the holes 22. At this time, if the positioning engagement protrusions 44 cannot be engaged with the positioning engagement holes 22 by pressing the positioning engagement protrusions 44 toward the groove inner wall 21A, the slide portion 43 is once removed from the side wall groove 20 and shown in FIG. As shown in the figure, it is inverted and inserted into the side wall groove 20, and the positioning engagement projection 44 is engaged with the positioning engagement hole 22 in a concavo-convex manner at the position where the work restricting portion 41 is brought into contact with the rolling bearing W.

位置決係合突起４４を位置決係合孔２２に凹凸係合させたらスライド部４３と側壁溝２０の溝前部壁１３Ｖとの隙間にスペーサ部品６０のスライド脚部６２を挿入する。そして、スペーサ部品６０の係止突起６４をコンテナ１０の上面フランジ１３Ｘに係止させる。これにより、スペーサ部品６０によってスライド部４３の水平移動が規制され、位置決係合突起４４と位置決係合孔２２との凹凸係合の解除が禁止され、跳上規制部品４０の側壁溝２０への取り付けが完了する。すると、両側壁溝２０，２０に取り付けられた跳上規制部品４０，４０のワーク規制部４１，４１が、図３に示すように、転がり軸受Ｗに上方から宛がわれた状態になり、転がり軸受Ｗの上方への跳ね上がりが規制される。 When the positioning engagement protrusion 44 is engaged with the positioning engagement hole 22 in a concave-convex manner, the slide leg portion 62 of the spacer component 60 is inserted into the gap between the slide portion 43 and the groove front wall 13V of the side wall groove 20. Then, the locking protrusion 64 of the spacer component 60 is locked to the upper surface flange 13X of the container 10. Accordingly, the horizontal movement of the slide portion 43 is restricted by the spacer part 60, the release of the concave / convex engagement between the positioning engagement protrusion 44 and the positioning engagement hole 22 is prohibited, and the side wall groove 20 of the jumping restriction part 40 is prohibited. Installation to is completed. Then, the work restricting portions 41 and 41 of the jumping restricting parts 40 and 40 attached to the both side wall grooves 20 and 20 are in a state where they are addressed to the rolling bearing W from above as shown in FIG. The upward jump of the bearing W is restricted.

上記したように本実施形態のコンテナ１０は、底面１２Ａが正方形をなし、その底面１２Ａに転がり軸受Ｗの一端面を重ねて収容するので、底面が長方形のコンテナに比べて内部のスペースの有効利用が図られる。しかも、その底面１２Ａの対角線上に延びた水平位置決溝１５Ｂの任意の位置決突片１６に４つの横ずれ規制部品３０が係合するので、それら４つの横ずれ規制部品３０を転がり軸受Ｗの外周面を４等分する位置に容易に宛がうことができる。これにより、従来のように一部の横ずれ規制部品３０に多大な負荷がかかって変形することが防がれ、安定して転がり軸受Ｗを搬送することが可能になる。また、横ずれ規制部品３０のうち転がり軸受Ｗに接触する位置決突部３１は円筒形状であるので、転がり軸受Ｗの表面に傷が付くことが防がれる。さらには、位置決突部３１の上端部が半球状になっているので、転がり軸受Ｗがコンテナ１０に収容される際に誤って位置決突部３１の上端部に当接しても、転がり軸受Ｗに傷が付き難い。 As described above, the container 10 according to the present embodiment has a bottom surface 12A that is square and accommodates one end surface of the rolling bearing W on the bottom surface 12A so as to effectively use the internal space as compared with a container having a rectangular bottom surface. Is planned. Moreover, since the four lateral displacement restricting parts 30 are engaged with the arbitrary positioning protrusions 16 of the horizontal positioning groove 15B extending on the diagonal line of the bottom surface 12A, the four lateral displacement restricting parts 30 are connected to the outer periphery of the rolling bearing W. The surface can be easily assigned to a position that divides the surface into four equal parts. As a result, it is possible to prevent a part of the lateral displacement restricting parts 30 from being deformed due to a great load as in the conventional case, and to stably transport the rolling bearing W. Moreover, since the positioning protrusion 31 which contacts the rolling bearing W among the lateral deviation restricting parts 30 has a cylindrical shape, the surface of the rolling bearing W is prevented from being damaged. Furthermore, since the upper end of the positioning protrusion 31 is hemispherical, even if the rolling bearing W is accidentally brought into contact with the upper end of the positioning protrusion 31 when being accommodated in the container 10, the rolling bearing W is hard to be damaged.
