Description

本発明は、自動倉庫のラック装置に関する。 The present invention relates to a rack device for an automatic warehouse.

従来の自動倉庫のラック装置は、支柱部材、梁部材、ブレース部材、及び荷受棚部等を、備えている。このようなラック装置では、地震等によって物品等が荷受棚部から落下しないように、荷受棚部に滑り防止面が設けられている（特許文献１を参照）。このようなラック装置では、荷受棚部に滑り防止面を設けることによって、収納効率を低下させることなく、地震時の物品の落下を防止している。また、従来のラック装置では、荷受棚部の棚受け本体において物品が当接する部分と、荷受棚部の腕木との間に、粘弾性体が配置されものがある（特許文献２を参照）。このようなラック装置では、物品の荷重を、粘弾性体で支持しながら腕木へと伝達することによって、地震時の物品の落下を防止している。 A conventional rack device for an automatic warehouse includes a column member, a beam member, a brace member, a load receiving shelf portion, and the like. In such a rack device, an anti-slip surface is provided on the load receiving shelf so that articles and the like do not fall from the load receiving shelf due to an earthquake or the like (see Patent Document 1). In such a rack apparatus, by providing an anti-slip surface on the load receiving shelf part, the articles are prevented from falling during an earthquake without lowering the storage efficiency. Moreover, in the conventional rack apparatus, there exists a thing by which a viscoelastic body is arrange | positioned between the part which articles | goods contact in the shelf receiving body of a load receiving shelf part, and the arm of a load receiving shelf part (refer patent document 2). In such a rack apparatus, the load of an article is transmitted to the arm while being supported by a viscoelastic body, thereby preventing the article from falling during an earthquake.

従来の自動倉庫のラック装置には、滑り防止面を荷受棚部に設けることによって、物品の落下防止措置が施されていた。しかしながら、地震力が大きくなって、滑り防止面の摩擦力を上回る力が、物品に作用した場合、物品が荷受棚部から落下してしまうおそれがある。また、様々に変化する地震力に対応できるように、滑り防止面の摩擦係数を一意に決定することも難しい。
また、他の自動倉庫のラック装置には、物品の荷重を、粘弾性体で支持しながら腕木へと伝達することによって、物品の落下防止措置が施されたものもある。しかしながら、この形態のラック装置では、粘弾性体の上部に物品が載置されるので、物品の重量によって粘弾性体が変形しづらくなるおそれがある。Conventional rack devices for automatic warehouses have been provided with measures to prevent articles from falling by providing an anti-slip surface on the load receiving shelf. However, when the seismic force increases and a force exceeding the frictional force of the anti-slip surface acts on the article, the article may fall from the load receiving shelf. It is also difficult to uniquely determine the friction coefficient of the anti-slip surface so that it can cope with various seismic forces.
In addition, other automatic warehouse rack devices are provided with measures to prevent the articles from falling by transmitting the load of the articles to the arms while being supported by a viscoelastic body. However, in the rack device of this embodiment, since the article is placed on the upper part of the viscoelastic body, the viscoelastic body may not be easily deformed by the weight of the article.

本発明の課題は、物品の落下を効果的に防止可能な物品落下防止機構を、ラック装置に設置することにある。 It is an object of the present invention to install an article fall prevention mechanism in a rack device that can effectively prevent an article from falling.

以下に、課題を解決するための手段として複数の態様を説明する。これら態様は、必要に応じて任意に組み合せることができる。 Hereinafter, a plurality of modes will be described as means for solving the problems. These aspects can be arbitrarily combined as necessary.

本発明の一見地に係る自動倉庫のラック装置は、スタッカークレーンの経路と平行に配置される装置である。自動倉庫のラック装置は、支柱と、固定部と、移動式荷受部材と、粘弾性体とを、備えている。支柱は、上下方向に延びる部材である。固定部は、支柱に固定される部分である。固定部は、経路から離れる方向に延びる水平部材を、有している。移動式荷受部材は、下方が開放するように上部と両側部とから構成された断面を、有している。移動式荷受部材の上部が水平部材の上面に対向するように、移動式荷受部材は水平部材に載置される。粘弾性体は、水平部材の一側面と移動式荷受部材の側部の内側面との間に配置され、固定部と移動式荷受部材とを接続する。 An automatic warehouse rack apparatus according to an aspect of the present invention is an apparatus arranged in parallel with a path of a stacker crane. The rack device of an automatic warehouse includes a support column, a fixed portion, a movable load receiving member, and a viscoelastic body. A support | pillar is a member extended in an up-down direction. The fixing part is a part fixed to the support column. The fixing part has a horizontal member extending in a direction away from the path. The movable load receiving member has a cross section composed of an upper part and both side parts so that the lower part is opened. The movable load receiving member is placed on the horizontal member such that the upper portion of the movable load receiving member faces the upper surface of the horizontal member. The viscoelastic body is disposed between one side surface of the horizontal member and the inner side surface of the side portion of the movable load receiving member, and connects the fixed portion and the movable load receiving member.

この場合、例えば、物品が移動式荷受部材の上部に載置された状態で、ラック装置に地震力が入力されると、移動式荷受部材（又は水平部材）が、水平部材（又は移動式荷受部材）に対して、相対移動する。すると、粘弾性体が移動式荷受部材と水平部材との間で変形する。このように、物品落下防止機構は機能する。すなわち、移動式荷受部材が水平部材に対して相対移動を繰り返すことによって、物品に入力される地震エネルギーが、粘弾性体によって運動エネルギーから熱エネルギーに変換される。これにより、物品の落下を防止することができる。 In this case, for example, when the seismic force is input to the rack device in a state where the article is placed on the upper part of the movable load receiving member, the movable load receiving member (or the horizontal member) becomes the horizontal member (or the movable load receiving member). Relative to the member. Then, the viscoelastic body is deformed between the movable load receiving member and the horizontal member. Thus, the article fall prevention mechanism functions. That is, when the movable load receiving member repeats relative movement with respect to the horizontal member, the seismic energy input to the article is converted from kinetic energy to thermal energy by the viscoelastic body. Thereby, the fall of articles can be prevented.

上記のような構成を有するラック装置では、粘弾性体が、水平部材の一側面と移動式荷受部材の一方の側部の内側面との間に配置されているので、物品の垂直荷重は水平部材で直接的に支持し、物品の水平荷重は粘弾性体に直接的に伝達することができる。すなわち、物品の荷重が重くなっても、粘弾性体を効果的に動作させることができる。これにより、物品を支持しながら、物品の落下防止を確実に実現することができる。
また、本ラック装置では、水平部材が、下方が開放したコ字状断面を有する荷受部材の内側に配置されるので、スタッカークレーンの経路方向への移動式荷受部材の移動を、規制することができる。また、移動式荷受部材を、水平部材上において、スムーズに移動させることができる。これにより、粘弾性体を確実に変形させることができるので、ラック装置からの物品の脱落等を確実に防止することができる。In the rack apparatus having the above-described configuration, the viscoelastic body is disposed between one side surface of the horizontal member and the inner side surface of one side portion of the movable load receiving member. It is directly supported by the member, and the horizontal load of the article can be directly transmitted to the viscoelastic body. That is, the viscoelastic body can be effectively operated even when the load of the article becomes heavy. Thereby, the fall prevention of an article | item can be implement | achieved reliably, supporting an article | item.
Moreover, in this rack apparatus, since a horizontal member is arrange | positioned inside the cargo receiving member which has the U-shaped cross section which the downward | lower direction was open | released, it is possible to regulate the movement of the movable cargo receiving member in the path direction of the stacker crane. it can. In addition, the movable load receiving member can be smoothly moved on the horizontal member. Thereby, since the viscoelastic body can be reliably deformed, it is possible to reliably prevent the articles from dropping off from the rack device.

さらに、本ラック装置では、荷受部材と水平部材との間に粘弾性体を配置するだけで、様々に変化する地震力に対して、物品の落下を効果的に防止することができる。すなわち、物品落下防止機構を容易且つ低コストでラック装置に設置することができる。また、固定部と荷受部材とを有する荷受棚部は、必ずしもラック装置の全ての荷受棚部に設置する必要はない。すなわち、この荷受棚部を、必要に応じて、ラック装置に部分的に設置することによって、さらに低コスト化を図ることができる。 Furthermore, in this rack apparatus, the article can be effectively prevented from falling against variously changing seismic forces simply by arranging a viscoelastic body between the cargo receiving member and the horizontal member. That is, the article fall prevention mechanism can be easily and inexpensively installed on the rack device. Moreover, it is not always necessary to install the load receiving shelf portion having the fixed portion and the load receiving member in all the load receiving shelf portions of the rack device. That is, it is possible to further reduce the cost by partially installing the cargo receiving shelf portion in the rack device as necessary.

なお、一般的には、ラック装置では、経路から離れる方向の一側面は、物品を出し入れするために、開口が設けられている。また、経路から離れる方向の長さは、経路方向の長さと比較して、短くなっている（アスペクト比が小さくなっている）。このため、ラック装置に載置された物品は、地震時等に、上記の一側面の開口から脱落してしまうおそれがある。しかしながら、本ラック装置では、経路から離れる方向に、上記のような機構を設けることによって、ラック装置からの物品の脱落等を確実に防止することができる。 In general, in a rack apparatus, one side surface in a direction away from the path is provided with an opening for taking in and out articles. Further, the length in the direction away from the path is shorter (the aspect ratio is smaller) than the length in the path direction. For this reason, the articles placed on the rack device may fall out of the opening on the one side surface during an earthquake or the like. However, in this rack apparatus, by providing the mechanism as described above in the direction away from the path, it is possible to reliably prevent the articles from dropping off from the rack apparatus.

ラック装置では、支柱が、第１の支柱と、第２の支柱とを、有していてもよい。また、固定部は、第１の固定部と、第２の固定部とを、有していてもよい。第１の支柱は、スタッカークレーンに近い側に配置される支柱である。第２の支柱は、スタッカークレーンから離れた側に配置される支柱である。第１の支柱には第１の固定部が固定され、第２の支柱には第２の固定部が固定されている。移動式荷受部材は、第１の固定部と第２の固定部とによって、支持される。
この場合、移動式荷受部材が、第１の固定部と第２の固定部とによって、支持されるので、移動式荷受部材を安定的に固定部に対して移動させることができる。これにより、粘弾性体を確実に変形させることができるので、ラック装置からの物品の脱落等を確実に防止することができる。また、固定部を、経路から離れる方向に分割した構造にすることによって、さらに低コスト化を図ることができる。In the rack device, the support column may include a first support column and a second support column. Moreover, the fixing part may have a first fixing part and a second fixing part. A 1st support | pillar is a support | pillar arrange | positioned at the side near a stacker crane. A 2nd support | pillar is a support | pillar arrange | positioned in the side away from the stacker crane. A first fixing portion is fixed to the first support column, and a second fixing portion is fixed to the second support column. The movable load receiving member is supported by the first fixing portion and the second fixing portion.
In this case, since the movable load receiving member is supported by the first fixed portion and the second fixed portion, the movable load receiving member can be stably moved with respect to the fixed portion. Thereby, since the viscoelastic body can be reliably deformed, it is possible to reliably prevent the articles from dropping off from the rack device. Further, the cost can be further reduced by making the fixed portion divided in a direction away from the route.

ラック装置は、低摩擦部材をさらに備えていてもよい。低摩擦部材は、水平部材の上面に取り付けられる。低摩擦部材は、移動式荷受部材の上部の内側面に当接する。低摩擦部材は、物品落下防止機構に含まれる。
この場合、低摩擦部材が、水平部材の上面と移動式荷受部材の内側上面との間に、配置されているので、移動式荷受部材を、水平部材上において、よりスムーズに移動させることができる。これにより、粘弾性体をより確実に変形させることができるので、ラック装置からの物品の脱落等を確実に防止することができる。The rack device may further include a low friction member. The low friction member is attached to the upper surface of the horizontal member. The low friction member abuts on the inner side surface of the upper part of the movable load receiving member. The low friction member is included in the article fall prevention mechanism.
In this case, since the low friction member is disposed between the upper surface of the horizontal member and the inner upper surface of the movable load receiving member, the movable load receiving member can be moved more smoothly on the horizontal member. . As a result, the viscoelastic body can be more reliably deformed, so that the articles can be prevented from dropping off from the rack device.

ラック装置では、固定部が支持部材をさらに有していてもよい。支持部材は、支柱と水平部材とを連結して、水平部材を支持する。移動式荷受部材は、移動量に対応する切欠部を、有している。切欠部には、支持部材が嵌合される。
この場合、移動式荷受部材が水平部材の上部に載置されると、移動式荷受部材の切欠部が、支持部材に嵌合される。この場合、支持部材が切欠部の内側に配置された状態で、移動式荷受部材は移動する。そして、移動式荷受部材の移動量が大きくなると、移動式荷受部材の切欠部の縁部が、支持部材に当接する。このように、移動式荷受部材に切欠部を設け、この切欠部の内側に支持部材を配置することによって、移動式荷受部材の移動方向への抜け出しを、規制することができる。In the rack apparatus, the fixing unit may further include a support member. The support member supports the horizontal member by connecting the column and the horizontal member. The movable load receiving member has a notch corresponding to the amount of movement. A support member is fitted into the notch.
In this case, when the movable load receiving member is placed on the upper part of the horizontal member, the cutout portion of the movable load receiving member is fitted to the support member. In this case, the movable load receiving member moves in a state where the support member is disposed inside the notch. When the movement amount of the movable load receiving member increases, the edge of the cutout portion of the movable load receiving member comes into contact with the support member. In this way, by providing the movable load receiving member with the notch and arranging the support member inside the notch, it is possible to restrict the movement of the movable load receiving member in the moving direction.

ラック装置では、固定部と、移動式荷受部材と、粘弾性体とによって、移動式荷受棚部が構成されていてもよい。また、固定部と、固定式荷受部材とによって、固定式荷受棚部が構成されていてもよい。固定式荷受部材は、固定部に固定される。移動式荷受棚部は、ラック装置本体の上段側に設けられ、固定式荷受棚部はラック装置本体の下段側に設けられる。
この場合、移動式荷受棚部が、ラック装置の上段側にのみ設けられている。すなわち、地震時等に振幅が大きくなるラック装置の上段側にのみ、移動式荷受棚部が設けられている。このように、必要な部分にのみ、移動式荷受棚部を設けることによって、ラック装置の全段に移動式荷受棚部を設ける場合と比較して、低コスト化を図ることができる。In the rack apparatus, the mobile load receiving shelf portion may be configured by the fixed portion, the mobile load receiving member, and the viscoelastic body. Moreover, the fixed load receiving shelf portion may be configured by the fixed portion and the fixed load receiving member. The fixed load receiving member is fixed to the fixed portion. The movable load receiving shelf is provided on the upper side of the rack apparatus main body, and the fixed load receiving shelf is provided on the lower side of the rack apparatus main body.
In this case, the mobile load receiving shelf is provided only on the upper side of the rack device. In other words, the mobile load receiving shelf is provided only on the upper side of the rack device whose amplitude increases during an earthquake or the like. As described above, by providing the mobile load receiving shelf only at a necessary portion, the cost can be reduced as compared with the case where the mobile load receiving shelf is provided at all stages of the rack device.

本発明に係る自動倉庫のラック装置は、ラック装置に物品落下防止機構を設置することによって、物品の落下を効果的に防止することができる。 The rack apparatus of the automatic warehouse according to the present invention can effectively prevent the articles from falling by installing the article fall prevention mechanism in the rack apparatus.

Similarly, the second support member 64b is fixed to the second support column 21b so as to be parallel to the path. The second support member 64b connects the second support column 21b and the second horizontal member 63b. A second horizontal member 63b is fixed to the distal end portion of the second support member 64b. The second support member 64b and the second horizontal member 63b are orthogonal to each other.
That is, each of the first support member 64a and the second support member 64b is arranged to be parallel to each other and is fixed to the first support column 21a and the second support column 21b. The first support member 64a and the second support member 64b support the movable load receiving member 70 via the first horizontal member 63a and the second horizontal member 63b.

移動式荷受部材７０は、物品を受ける部材である。移動式荷受部材７０は、一対の固定部６１，６２（第１の固定部及び第２の固定部）の上部において、経路から離れる方向及び経路に近づく方向の少なくともいずれか一方の方向に、移動可能なように、載置される。具体的には、荷受部材７０は、一対の水平部材６３ａ，６３ｂ（第１の水平部材及び第２の水平部材）の上部に、移動可能に配置される。言い換えると、荷受部材７０は、一対の水平部材６３ａ，６３ｂの間に架け渡され、一対の水平部材６３ａ，６３ｂに対して移動可能である。荷受部材７０は、一対の水平部材６３ａ，６３ｂを介して、一対の支持部材６４ａ，６４ｂによって支持される。 The mobile load receiving member 70 is a member that receives an article. The movable load receiving member 70 moves in the upper direction of the pair of fixing portions 61 and 62 (first fixing portion and second fixing portion) in at least one of a direction away from the route and a direction approaching the route. Placed as possible. Specifically, the cargo receiving member 70 is movably disposed above the pair of horizontal members 63a and 63b (a first horizontal member and a second horizontal member). In other words, the cargo receiving member 70 is bridged between the pair of horizontal members 63a and 63b and is movable with respect to the pair of horizontal members 63a and 63b. The cargo receiving member 70 is supported by a pair of support members 64a and 64b via a pair of horizontal members 63a and 63b.

移動式荷受部材７０は、下方が開放したコ字状断面を、有している。具体的には、荷受部材７０は、互いに対向する一対の壁部７１（側部の一例）と、一対の壁部７１を連結する連結部７２（上部の一例）と、一方の壁部７１の端部に一体に形成された抜止部７３とを、有している。ここでは、連結部７２の内面である下面が水平部材６３ａ，６３ｂの上面に対向し、一対の壁部７１の内面が水平部材６３ａ，６３ｂの側面に対向し、抜止部７３が水平部材６３ａ，６３ｂの下方に位置するように、荷受部材７０は一対の水平部材６３ａ，６３ｂの上部に移動可能に載置される。 The movable load receiving member 70 has a U-shaped cross section that is open at the bottom. Specifically, the load receiving member 70 includes a pair of wall portions 71 (an example of side portions) facing each other, a connecting portion 72 (an example of an upper portion) that connects the pair of wall portions 71, and one wall portion 71. And a retaining portion 73 formed integrally with the end portion. Here, the lower surface, which is the inner surface of the connecting portion 72, faces the upper surfaces of the horizontal members 63a, 63b, the inner surfaces of the pair of wall portions 71 face the side surfaces of the horizontal members 63a, 63b, and the retaining portions 73 are the horizontal members 63a, 63b. The load receiving member 70 is movably placed on top of the pair of horizontal members 63a and 63b so as to be positioned below 63b.

また、荷受部材７０には、切欠部７５が設けられている。切欠部７５は、一対の壁部７１のいずれか一方に矩形状に形成されている。切欠部７５は、支持部材６４ａ，６４ｂに嵌合される。切欠部７５における切欠範囲（軸方向の切欠幅）は、荷受部材７０の許容移動量に対応している。このため、支持部材６４ａ，６４ｂが荷受部材７０の切欠部７５の内部に位置している場合、荷受部材７０は一対の水平部材６３ａ，６３ｂ上で移動する。一方で、支持部材６４ａ，６４ｂが荷受部材７０の切欠部７５の内縁部に当接した場合、荷受部材７０は停止する。このように、切欠部７５はストッパとして機能する。 The cargo receiving member 70 is provided with a notch 75. The notch 75 is formed in a rectangular shape on one of the pair of walls 71. The notch 75 is fitted into the support members 64a and 64b. The notch range (notch width in the axial direction) in the notch 75 corresponds to the allowable movement amount of the load receiving member 70. For this reason, when the support members 64a and 64b are located inside the notch 75 of the load receiving member 70, the load receiving member 70 moves on the pair of horizontal members 63a and 63b. On the other hand, when the support members 64 a and 64 b abut on the inner edge portion of the cutout portion 75 of the load receiving member 70, the load receiving member 70 stops. Thus, the notch 75 functions as a stopper.

粘弾性体８０は、運動エネルギーを熱エネルギーに変換する。粘弾性体８０は、固定部６０と移動式荷受部材７０との間に配置され、固定部６０と移動式荷受部材７０とを接続する。粘弾性体８０は、水平部材６３ａ，６３ｂと移動式荷受部材７０との間に配置される。具体的には、粘弾性体８０は、矩形板状に形成されている。粘弾性体８０は、水平部材６３ａ，６３ｂの一側面と、水平部材６３ａ，６３ｂの一側面に対向した荷受部材７０の内側壁面とに、取り付けられる。この状態で、荷受部材７０が水平部材６３ａ，６３ｂ上で移動した場合、粘弾性体８０は剪断変形し、エネルギーを吸収する。なお、粘弾性体８０は、水平部材６３ａ，６３ｂ上で移動した荷受部材７０を、弾性力によって、ラック装置１の移動前の位置（初期位置）に引き戻す手段でもある。ラック装置１が初期位置に位置する場合、粘弾性体８０は、粘弾性体８０に歪みが生じていない状態にある。 The viscoelastic body 80 converts kinetic energy into heat energy. The viscoelastic body 80 is disposed between the fixed portion 60 and the movable load receiving member 70 and connects the fixed portion 60 and the movable load receiving member 70. The viscoelastic body 80 is disposed between the horizontal members 63 a and 63 b and the movable load receiving member 70. Specifically, the viscoelastic body 80 is formed in a rectangular plate shape. The viscoelastic body 80 is attached to one side surface of the horizontal members 63a and 63b and the inner wall surface of the cargo receiving member 70 facing the one side surface of the horizontal members 63a and 63b. In this state, when the cargo receiving member 70 moves on the horizontal members 63a and 63b, the viscoelastic body 80 undergoes shear deformation and absorbs energy. The viscoelastic body 80 is also means for pulling the load receiving member 70 moved on the horizontal members 63a and 63b back to the position (initial position) before the rack device 1 is moved by elastic force. When the rack apparatus 1 is located at the initial position, the viscoelastic body 80 is in a state where the viscoelastic body 80 is not distorted.

低摩擦部材９０は、矩形板状に形成されている。低摩擦部材９０は、水平部材６３ａ，６３ｂの上面に取り付けられる。この状態で荷受部材７０が水平部材６３ａ，６３ｂの上部に載置されると、低摩擦部材９０は、荷受部材７０の内側上面に当接する。すなわち、この状態では、低摩擦部材９０は、荷受部材７０の内側上面と水平部材６３ａ，６３ｂの上面との間に、配置される。 The low friction member 90 is formed in a rectangular plate shape. The low friction member 90 is attached to the upper surfaces of the horizontal members 63a and 63b. When the load receiving member 70 is placed on the upper portions of the horizontal members 63 a and 63 b in this state, the low friction member 90 comes into contact with the inner upper surface of the load receiving member 70. That is, in this state, the low friction member 90 is disposed between the inner upper surface of the load receiving member 70 and the upper surfaces of the horizontal members 63a and 63b.

低摩擦部材９０は、摺動抵抗が低い材質によって形成されている。低摩擦部材９０は、例えば、超高分子量ポリエチレンから構成されている。上記のような低摩擦部材９０を、移動式荷受部材７０の内側上面に当接させることによって、移動式荷受部材７０が水平部材６３ａ，６３ｂの上部において摺動しやすくしている。 The low friction member 90 is made of a material having low sliding resistance. The low friction member 90 is made of, for example, ultra high molecular weight polyethylene. By bringing the low friction member 90 as described above into contact with the inner upper surface of the movable load receiving member 70, the movable load receiving member 70 can easily slide on the upper portions of the horizontal members 63a and 63b.

（３）実施形態の作用効果
（Ａ）自動倉庫のラック装置１は、スタッカークレーン１００の経路と平行に配置される装置である。自動倉庫のラック装置１は、支柱２１と、固定部６０と、移動式荷受部材７０と、粘弾性体８０とを、備えている。支柱２１は、上下方向に延びる部材である。固定部６０は、支柱２１に固定される部分である。固定部６０は、経路から離れる方向に延びる水平部材６３を、有している。移動式荷受部材７０は、下方が開放するように連結部７２と一対の壁部７１とから構成された断面を、有している。移動式荷受部材７０の連結部７２が水平部材６３の上面に対向するように、移動式荷受部材７０は水平部材６３に載置される。粘弾性体８０は、水平部材６３の一側面と移動式荷受部材７０の一方の壁部７１の内側面との間に配置され、固定部６０と移動式荷受部材７０とを接続する。(3) Effects of Embodiment (A) The rack device 1 of an automatic warehouse is a device arranged in parallel with the path of the stacker crane 100. The automatic warehouse rack apparatus 1 includes a column 21, a fixed portion 60, a movable load receiving member 70, and a viscoelastic body 80. The support | pillar 21 is a member extended in an up-down direction. The fixing part 60 is a part fixed to the support column 21. The fixing part 60 has a horizontal member 63 extending in a direction away from the path. The movable load receiving member 70 has a cross section composed of a connecting portion 72 and a pair of wall portions 71 so that the lower portion is opened. The movable load receiving member 70 is placed on the horizontal member 63 so that the connecting portion 72 of the movable load receiving member 70 faces the upper surface of the horizontal member 63. The viscoelastic body 80 is disposed between one side surface of the horizontal member 63 and the inner side surface of one wall portion 71 of the movable load receiving member 70, and connects the fixed portion 60 and the movable load receiving member 70.

この場合、例えば、物品が移動式荷受部材７０の上部に載置された状態で、ラック装置１に地震力が入力されると、移動式荷受部材７０（又は水平部材６３）が、水平部材６３（又は移動式荷受部材７０）に対して、相対移動する。すると、粘弾性体８０が移動式荷受部材７０と水平部材６３との間で変形する。このように、物品落下防止機構５は機能する。すなわち、移動式荷受部材７０が水平部材６３に対して相対移動を繰り返すことによって、物品に入力される地震エネルギーが、粘弾性体８０によって運動エネルギーから熱エネルギーに変換される。これにより、物品の落下を防止することができる。 In this case, for example, when the seismic force is input to the rack device 1 in a state where the article is placed on the upper part of the movable load receiving member 70, the movable load receiving member 70 (or the horizontal member 63) is changed to the horizontal member 63. It moves relative to (or the movable load receiving member 70). Then, the viscoelastic body 80 is deformed between the movable load receiving member 70 and the horizontal member 63. Thus, the article drop prevention mechanism 5 functions. That is, when the movable load receiving member 70 repeats relative movement with respect to the horizontal member 63, the seismic energy input to the article is converted from kinetic energy to thermal energy by the viscoelastic body 80. Thereby, the fall of articles can be prevented.

上記のような構成を有するラック装置１では、粘弾性体８０が、水平部材６３の一側面と移動式荷受部材７０の一方の壁部７１の内側面との間に配置されているので、物品の垂直荷重は水平部材６３で直接的に支持し、物品の水平荷重は粘弾性体８０に直接的に伝達することができる。すなわち、物品の荷重が重くなっても、粘弾性体８０を効果的に動作させることができる。これにより、物品を支持しながら、物品の落下防止を確実に実現することができる。
また、本ラック装置１では、水平部材６３が、下方が開放したコ字状断面を有する荷受部材７０の内側に配置されるので、スタッカークレーン１００の経路方向への移動式荷受部材７０の移動を、規制することができる。また、移動式荷受部材７０を、水平部材６３上において、スムーズに移動させることができる。これにより、粘弾性体８０を確実に変形させることができるので、ラック装置１からの物品の脱落等を確実に防止することができる。In the rack apparatus 1 having the above-described configuration, the viscoelastic body 80 is disposed between one side surface of the horizontal member 63 and the inner side surface of the one wall portion 71 of the movable load receiving member 70. The vertical load is directly supported by the horizontal member 63, and the horizontal load of the article can be directly transmitted to the viscoelastic body 80. That is, the viscoelastic body 80 can be effectively operated even when the load of the article becomes heavy. Thereby, the fall prevention of an article | item can be implement | achieved reliably, supporting an article | item.
Moreover, in this rack apparatus 1, since the horizontal member 63 is arrange | positioned inside the load receiving member 70 which has the U-shaped cross section which the downward | lower direction was open | released, the movement of the movable load receiving member 70 to the path | route direction of the stacker crane 100 is carried out. Can be regulated. In addition, the movable load receiving member 70 can be smoothly moved on the horizontal member 63. Thereby, since the viscoelastic body 80 can be reliably deformed, it is possible to reliably prevent the articles from dropping from the rack apparatus 1.

さらに、本ラック装置１では、荷受部材７０と水平部材６３との間に粘弾性体８０を配置するだけで、様々に変化する地震力に対して、物品の落下を効果的に防止することができる。すなわち、物品落下防止機構５を容易且つ低コストでラック装置１に設置することができる。また、固定部６０と荷受部材７０とを有する荷受棚部５０は、必ずしもラック装置１の全ての荷受棚部に設置する必要はない。すなわち、この荷受棚部５０を、必要に応じて、ラック装置１に部分的に設置することによって、さらに低コスト化を図ることができる。 Furthermore, in the rack apparatus 1, the article can be effectively prevented from falling against various changing seismic forces simply by arranging the viscoelastic body 80 between the cargo receiving member 70 and the horizontal member 63. it can. That is, the article fall prevention mechanism 5 can be installed in the rack apparatus 1 easily and at low cost. In addition, the load receiving shelf portion 50 having the fixed portion 60 and the load receiving member 70 is not necessarily installed in all the load receiving shelf portions of the rack device 1. That is, it is possible to further reduce the cost by partially installing the cargo receiving shelf 50 in the rack device 1 as necessary.

なお、一般的には、ラック装置１では、経路から離れる方向の一側面は、物品を出し入れするために、開口が設けられている。また、経路から離れる方向の長さは、経路方向の長さと比較して、短くなっている（アスペクト比が小さくなっている）。このため、ラック装置１に載置された物品は、地震時等に、上記の一側面の開口から脱落してしまうおそれがある。しかしながら、本ラック装置１では、経路から離れる方向に、上記のような機構を設けることによって、ラック装置１からの物品の脱落等を確実に防止することができる。 In general, in the rack device 1, an opening is provided on one side surface in a direction away from the path in order to take in and out articles. Further, the length in the direction away from the path is shorter (the aspect ratio is smaller) than the length in the path direction. For this reason, the articles placed on the rack device 1 may fall out of the opening on the one side surface during an earthquake or the like. However, in the present rack apparatus 1, by providing the mechanism as described above in the direction away from the path, it is possible to reliably prevent articles from dropping off from the rack apparatus 1.

（Ｂ）自動倉庫のラック装置１では、支柱２１が、第１の支柱２１ａと、第２の支柱２１ｂとを、有していてもよい。また、固定部６０は、第１の固定部６１と、第２の固定部６２とを、有していてもよい。第１の支柱２１ａは、スタッカークレーン１００に近い側に配置される支柱２１である。第２の支柱２１ｂは、スタッカークレーン１００から離れた側に配置される支柱２１である。第１の支柱２１ａには第１の固定部６１が固定され、第２の支柱２１ｂには第２の固定部６２が固定されている。移動式荷受部材７０は、第１の固定部６１と第２の固定部６２とによって、支持される。 (B) In the rack apparatus 1 of an automatic warehouse, the support | pillar 21 may have the 1st support | pillar 21a and the 2nd support | pillar 21b. Further, the fixing part 60 may have a first fixing part 61 and a second fixing part 62. The first support column 21 a is a support column 21 disposed on the side close to the stacker crane 100. The second support column 21 b is a support column 21 disposed on the side away from the stacker crane 100. A first fixing portion 61 is fixed to the first support column 21a, and a second fixing portion 62 is fixed to the second support column 21b. The movable load receiving member 70 is supported by the first fixing portion 61 and the second fixing portion 62.

この場合、移動式荷受部材７０が、第１の固定部６１と第２の固定部６２とによって、支持されるので、移動式荷受部材７０を安定的に固定部６０に対して移動させることができる。これにより、粘弾性体８０を確実に変形させることができるので、ラック装置１からの物品の脱落等を確実に防止することができる。また、固定部６０を、経路から離れる方向に分割した構造にすることによって、さらに低コスト化を図ることができる。 In this case, since the movable load receiving member 70 is supported by the first fixed portion 61 and the second fixed portion 62, the movable load receiving member 70 can be stably moved with respect to the fixed portion 60. it can. Thereby, since the viscoelastic body 80 can be reliably deformed, it is possible to reliably prevent the articles from dropping from the rack apparatus 1. Further, the cost can be further reduced by making the fixing portion 60 divided in a direction away from the route.

（Ｃ）自動倉庫のラック装置１では、低摩擦部材９０をさらに備えている。低摩擦部材９０は、水平部材６３の上面に取り付けられる。低摩擦部材９０は、移動式荷受部材７０の連結部７２の内側面に当接する。低摩擦部材９０は、物品落下防止機構５に含まれる。 (C) The rack device 1 of the automatic warehouse further includes a low friction member 90. The low friction member 90 is attached to the upper surface of the horizontal member 63. The low friction member 90 abuts on the inner surface of the connecting portion 72 of the movable load receiving member 70. The low friction member 90 is included in the article fall prevention mechanism 5.

この場合、低摩擦部材９０が、水平部材６３の上面と移動式荷受部材７０の内側上面との間に、配置されているので、移動式荷受部材７０を、水平部材６３上において、よりスムーズに移動させることができる。これにより、粘弾性体８０をより確実に変形させることができるので、ラック装置１からの物品の脱落等を確実に防止することができる。 In this case, since the low friction member 90 is disposed between the upper surface of the horizontal member 63 and the inner upper surface of the movable load receiving member 70, the movable load receiving member 70 is more smoothly moved on the horizontal member 63. Can be moved. Thereby, since the viscoelastic body 80 can be more reliably deformed, it is possible to reliably prevent the articles from dropping off from the rack apparatus 1.

（Ｄ）自動倉庫のラック装置１では、固定部６０が支持部材６４をさらに有していてもよい。支持部材６４は、支柱２１と水平部材６３とを連結して、水平部材６３を支持する。移動式荷受部材７０は、移動量に対応する切欠部７５を、有している。切欠部７５には、支持部材６４が嵌合される。
この場合、移動式荷受部材７０が水平部材６３の上部に載置されると、移動式荷受部材７０の切欠部７５が、支持部材６４に嵌合される。この場合、支持部材６４が切欠部７５の内側に配置された状態で、移動式荷受部材７０は移動する。そして、移動式荷受部材７０の移動量が大きくなると、移動式荷受部材７０の切欠部７５の縁部が、支持部材６４に当接する。このように、移動式荷受部材７０に切欠部７５を設け、この切欠部７５の内側に支持部材６４を配置することによって、移動式荷受部材７０の移動方向への抜け出しを、規制することができる。(D) In the rack device 1 of an automatic warehouse, the fixed part 60 may further include a support member 64. The support member 64 connects the support column 21 and the horizontal member 63 to support the horizontal member 63. The movable load receiving member 70 has a notch 75 corresponding to the amount of movement. A support member 64 is fitted into the notch 75.
In this case, when the movable load receiving member 70 is placed on the upper part of the horizontal member 63, the notch 75 of the movable load receiving member 70 is fitted into the support member 64. In this case, the movable load receiving member 70 moves in a state where the support member 64 is disposed inside the notch 75. When the movement amount of the movable load receiving member 70 increases, the edge of the cutout portion 75 of the movable load receiving member 70 contacts the support member 64. In this manner, by providing the movable load receiving member 70 with the notch 75 and arranging the support member 64 inside the notch 75, it is possible to restrict the movement of the movable load receiving member 70 in the moving direction. .

（４）他の実施形態
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。特に、本明細書に書かれた複数の実施形態及び変形例は必要に応じて任意に組合せ可能である。(4) Other Embodiments Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the scope of the invention. In particular, a plurality of embodiments and modifications described in this specification can be arbitrarily combined as necessary.

（ａ）前記実施形態では、全ての荷受棚部５０が、移動式荷受棚部５０である場合の例を示したが、ラック装置本体２の下段側には固定式荷受棚部（図示しない）を設け、ラック装置本体２の上段側にのみ移動式荷受棚部５０を設けるようにしてもよい。 (A) In the above-described embodiment, an example in which all the load receiving shelf portions 50 are mobile load receiving shelf portions 50 has been shown, but a fixed load receiving shelf portion (not shown) is provided on the lower side of the rack apparatus body 2. And the movable load receiving shelf 50 may be provided only on the upper side of the rack apparatus body 2.

この場合、固定式荷受棚部は、一対の支持部材（固定部）と、一対の支持部材に架け渡された固定式荷受部材とから、構成される。固定式荷受棚部では、固定式荷受部材は、一対の支持部材に対して移動不能である。
このように、地震時等に振幅が大きくなるラック装置１の上段側にのみ、移動式荷受棚部５０を設けることによって、ラック装置１の全段に移動式荷受棚部５０を設ける場合と比較して、低コスト化を図ることができる。また、この場合も、上記と同様の効果を得ることができる。In this case, the fixed load receiving shelf portion is composed of a pair of support members (fixed portions) and a fixed load receiving member spanned between the pair of support members. In the fixed load receiving shelf, the fixed load receiving member is not movable with respect to the pair of support members.
In this way, by providing the mobile load receiving shelf 50 only on the upper side of the rack device 1 where the amplitude becomes large at the time of an earthquake or the like, compared to the case where the mobile load receiving shelf 50 is provided in all the stages of the rack device 1. Thus, cost reduction can be achieved. Also in this case, the same effect as described above can be obtained.

（ｂ）前記実施形態では、水平部材６３（第１の水平部材６３ａ、第２の水平部材６３ｂ）が、対応する支持部材６４（第１の支持部材６４ａ、第２の支持部材６４ｂ）に、個別に設けられる場合の例を示したが、水平部材６３は、第１の支持部材６４ａの先端部と第２の支持部材６４２の先端部とに架け渡すように固定してもよい。この場合は、水平部材６３は一部材によって構成される。また、この場合も、上記と同様の効果を得ることができる。 (B) In the embodiment, the horizontal member 63 (first horizontal member 63a, second horizontal member 63b) is replaced with the corresponding support member 64 (first support member 64a, second support member 64b). Although the example in the case of providing separately is shown, the horizontal member 63 may be fixed so that it may span over the front-end | tip part of the 1st support member 64a, and the front-end | tip part of the 2nd support member 642. In this case, the horizontal member 63 is constituted by one member. Also in this case, the same effect as described above can be obtained.

（ｃ）前記実施形態では、荷受棚部５０が片持ち構造である場合の例を示したが、荷受棚部５０は両持ち構造であってもよい。例えば、図５に示すように、第１の支持部材１６４ａを、隣接する第１の支柱１２１ａの間に架け渡し、第２の支持部材１６４ｂを、隣接する第２の支柱１２１ｂの間に架け渡す。また、第１の支持部材１６４ａと第２の支持部材１６４ｂとの間に、互いに平行な一対の荷受部材１７０を架け渡す。
ここで、一対の支持部材１６４ａ，１６４ｂ（第１の支持部材及び第２の支持部材）それぞれ、及び一対の荷受部材１７０それぞれは、物品落下防止機構５を有している。例えば、一対の支持部材１６４ａ，１６４ｂ（第１の支持部材及び第２の支持部材）それぞれは、図４に示した構造を、有している。また、一対の荷受部材１７０それぞれは、図６に示すように、支持部材１６４ａ，１６４ｂの上面に固定されている。一対の荷受部材１７０それぞれの構成は、図６に示すように、抜止部７３を除いて、図４に示した構造と同じである。このため、図４と同じ部材については、同じ符号を付している。(C) In the above-described embodiment, an example in which the load receiving shelf 50 has a cantilever structure has been described. However, the load receiving shelf 50 may have a double-supported structure. For example, as shown in FIG. 5, the first support member 164a is bridged between the adjacent first columns 121a, and the second support member 164b is bridged between the adjacent second columns 121b. . In addition, a pair of load receiving members 170 parallel to each other are bridged between the first support member 164a and the second support member 164b.
Here, each of the pair of support members 164 a and 164 b (first support member and second support member) and each of the pair of load receiving members 170 includes the article fall prevention mechanism 5. For example, each of the pair of support members 164a and 164b (first support member and second support member) has the structure shown in FIG. Further, as shown in FIG. 6, each of the pair of load receiving members 170 is fixed to the upper surfaces of the support members 164a and 164b. The structure of each of the pair of load receiving members 170 is the same as the structure shown in FIG. 4 except for the retaining portion 73 as shown in FIG. For this reason, the same members as those in FIG.

さらに、図５に示すように、第１の支持部材１６４ａ及び第２の支持部材１６４ｂには、支柱１２１ａ，１２１ｂの近傍に、ストッパ１８０が設けられている。また、一対の荷受部材１７０には、両端部にストッパ１８１が設けられている。ストッパ１８０，１８１によって、各部材の物品落下防止機構５の移動が規制される。
このように、物品落下防止機構５を構成することによって、経路方向、及び経路に直交する方向への物品の落下を、防止することができる。また、この場合も、上記と同様の効果を得ることができる。Further, as shown in FIG. 5, the first support member 164a and the second support member 164b are provided with stoppers 180 in the vicinity of the columns 121a and 121b. The pair of load receiving members 170 are provided with stoppers 181 at both ends. The stoppers 180 and 181 restrict the movement of the article drop prevention mechanism 5 of each member.
In this way, by configuring the article fall prevention mechanism 5, it is possible to prevent the article from falling in the path direction and in the direction orthogonal to the path. Also in this case, the same effect as described above can be obtained.

本発明は、自動倉庫のラック装置に広く適用できる。 The present invention can be widely applied to rack devices in automatic warehouses.
