【発明の利用分野】
この発明は、入出庫装置がラック内に入り込んで作業するドライブラックに関する。
【0002】
【従来技術】
ラック内にフォークリフトなどの入出庫装置が進入して、パレットなどの単位で物品を入出庫するラックとして、ドライブインラックやドライブスルーラックが知られている。これらのラックを総称してドライブラックと呼ぶと、ラックの支持壁と支持壁との間隔はほぼパレット1個分であり、左右の支持壁に各々設けた棚受けに、パレットの左右の両端部を載置して、パレット単位で物品を保管する。従って、複数の物品を、支持壁にほぼ直角な方向(以下「幅方向」)に、並置することはできない。そして支持壁と支持壁との間の物品の収納スペースが、同時にフォークリフトなどが作業するスペースともなる。また棚受け毎にパレットを1段載置し、あるいは2段程度上下に重ねて載置し、床面への直置きの他に、棚を1〜3段程度設けて、パレット単位で物品を保管する。
【0003】
しかしながらこのようなドライブラックでは、複数の物品を支持壁と支持壁との間に幅方向に並置することはできず、物品の収納効率に限界がある。また複数物品を一括して入出庫できる入出庫装置を用いることもできず、入出庫の効率にも限界がある。
【0004】
【発明の課題】
この発明の基本的課題は、ドライブラックのラックの幅方向に沿って、複数個の物品を保管できるようにするとともに、入出庫装置の作業スペースを確保できるようにし、さらに物品からの荷重で支持壁が傾くことを防止することにある。
請求項2の発明での追加の課題は、棚を容易にスライドできるようにすると共に、棚をロックできるようにして、棚が妄動するのを防止することにある。
請求項3の発明での追加の課題は、物品の荷重が加わると、棚を自動的にロックできるようにすることにある。
【0005】
【発明の構成】
この発明は、支持壁と支持壁との間を、入出庫装置の作業スペース兼用の物品の保管スペースとしたドライブラックにおいて、支持壁と支持壁との間を掛け渡すように、支持壁に沿ってスライド自在な棚を設けて、この棚に支持壁にほぼ直角な方向に沿って複数の物品を載置自在にし、かつ前記棚のスライドにより、ドライブラック内に入出庫装置の作業スペースを形成するようにすると共に、前記棚に荷重が加わることにより下方に沈み込んで支持壁に嵌合する嵌合部を、前記棚に設けて、該嵌合により支持壁に直角な方向に沿っての棚と支持壁との相対的な位置を規制するようにしたことを特徴とする(請求項1)。
【0006】
好ましくは、前記支持壁にはレールを設置し、前記棚には車輪を設けて、前記レールに沿って棚を走行させることによりスライドさせるようにすると共に、棚の走行を禁止するためのロック手段を設ける(請求項2)。
【0007】
特に好ましくは、前記車輪と棚との間に、物品から棚に加わる荷重により変形する弾性体を設けて、該弾性体の変形によりロック片で棚をレールにロックするように、前記ロック手段を構成する(請求項3)。
【0008】
【発明の作用と効果】
この発明では、ドライブラックの支持壁と支持壁との間に、支持壁に沿ってスライド自在な棚を設けるので、棚上に複数の物品を支持壁と支持壁との間の方向(幅方向)に沿って並置できる。次に棚は支持壁に沿ってスライド自在なので、不要な棚をスライドさせることにより、入出庫装置が作業するための作業スペースを確保できる。これらのため、ドライブラックの収納効率を高め、また同時に複数物品を入出庫できる入出庫装置も使用可能にして、ドライブラックの入出庫の効率も改善できる(請求項1)。また棚に荷重が加わることにより下方に沈み込んで支持壁に嵌合する嵌合部を、棚に設けることにより、物品の荷重で棚と支持壁とがより緊密に固定され、支持壁が物品からの荷重で傾いたりすることを防止できる。
【0009】
請求項2の発明では、支持壁にレールを設置して、棚の車輪をこのレールで走行させるので、容易に棚をスライドできる。そして棚の走行を禁止するためのロック手段を設けるので、棚が妄動するのを防止できる。
【0010】
請求項3の発明では、棚に加わる物品の荷重により弾性体を変形させ、この変形で棚を自動的にロックできる。
【0011】
【実施例】
図1〜図3に、実施例のドライブインラックを示す。なお実施例はドライブインラックを例にするが、ドライブスルーラックでも同様である。またドライブインラック2の奥行き方向と幅方向は図3のように定め、奥行き方向手前から、フォークリフトなどの入出庫装置が支持壁4,6の間のスペースに進入して、入出庫するものとする。図には支持壁4,6を1枚ずつ示すが、これらを複数枚設けて、実施例のドライブインラック2を複数並置しても良い。さらに図では、棚12〜17を1層設けて、パレット19を床上に2段、棚12〜17に2段の、合計4段収納する例を示すが、支持壁4,6を鉛直方向に延長して、棚を複数層設けるようにしても良い。
【0012】
8は支持壁4,6の支柱で、支持壁4,6にはその奥行き方向に平行にレール10,11を設置し、棚12〜17をスライド自在に載置できるようにする。ただし最も奧側の棚12は固定で、スライドせず、最も手前の棚16,17は補助的な棚で、設けなくても良い。物品18は例えばパレット19上に積み付けて、入出庫及び収納し、パレット19とその上部の物品18をまとめて単に物品と呼ぶことがある。
【0013】
棚12〜17をスライド自在にすることにより、棚2枚分の作業スペース20を設けて、作業スペース20には棚が無いようにし、フォークリフトなどで棚上の物品の入出庫作業ができるようにする。作業スペース20の位置は、棚をスライドさせることにより移動自在である。またフォークリフトは、例えば複数パレット(ここでは2パレット)を、一括して入出庫及び搬送できるタイプのものとする。
【0014】
図2に棚13の構造を示すが、この構造は他の棚でも同様である。レール10,11の内で、レール10の上面にL字鋼22を取り付ける。レール10に対応する走行ユニット24では、車輪28を設けると共に、走行ユニット24の取り付け用の棒状部材32に、車輪28をロックするためのブレーキ片30と、棚13からの荷重を受けるための当接部34とを設け、バネ36などの弾性体を当接部34と車輪枠37との間に配置して、棚に加わる荷重で変形させる。このため棚にパレットが載置されると、バネ36が圧縮されて、ブレーキ片30が沈み込み、車輪28をロックし、車輪28をL字鋼22に対して固定する。図2の実線は、棚13に物品の荷重が加わっている際の位置を示し、鎖線は荷重が加わらず棚13が上昇している際の位置を示す。なおここでは、車輪28に当接するブレーキ片30によって、棚13の走行を禁止しているが、これに限るものではない。例えば、棚に加わる荷重によって弾性体が変形し、棚自体がレールに噛み込むことによって、棚の走行を禁止しても良い。このような例としては、断面C字等の枠体を、C字の両辺が断面三角形状のレールを跨ぐように、棚から弾性体を介して吊るし、荷重によって棚が下降すると、断面C字の枠体がレールに噛み込むようにする構成などがある。
【0015】
レール11側の走行ユニット26では、例えばレールとの接触面が平らな車輪29を用い、棒状部材42を車輪枠37に取り付け、その上部に当接部材44を遊動自在に配置して、当接部材44で棚13の荷重を受け、当接部材44と車輪枠37との間に、バネ40を配置する。バネ40が圧縮された場合、棒状部材42の先端は、孔部46に収容する。
【0016】
ここでは簡単のために、片側の走行ユニット24にのみ、車輪をロックするための手段を設け、L字鋼22を片側のレール10にのみ設けたが、棚の両側にロック手段付きの走行ユニット24とL字鋼22付きのレール10を設けても良い。またL字鋼22を用いると、幅方向に沿っての棚の位置を規制できるが、L字鋼22に代えてT字鋼を上下反転して用い、断面がH字状の車輪と組み合わせても、幅方向の棚の位置を規制できる。
【0017】
支持壁4,6を棚12〜17を用いて結合する。支持壁4,6には、支柱8などの位置で取付部材52を介してピン50を設け、ピン50はレール10,11に平行な向きにする。棚12〜17のプレート54に、ガイド溝56とこれに連通する嵌合部58とを設け、棚12〜17に荷重が加わっていないと、ピン50がガイド溝56の高さ位置にあるようにし、棚12〜17に荷重が加わり、バネ36,40により棚12〜17が沈み込むと、ピン50が嵌合部58の高さ位置に表れるようにする。
【0018】
図3に示すように、最も奧の棚12には、左右両端にプレート54を設けて、両端でピン50と嵌合自在にする。他の棚13〜15では、左右何れかにプレート54を設けて、ピン50と嵌合自在にし、かつプレートを設ける位置が、棚毎に左右が入れ替わるようにする。作業スペース20は棚2枚分で、棚13は空き棚になって退避する場合、鎖線で示した棚13bの位置までスライドし、この位置ではピン50と係合できてもできなくても良い。また棚14のスライド範囲は図3の位置から、棚13の手前側の位置までで、棚15のスライド範囲は図3の位置から棚13bの位置までである。
【0019】
棚15上の補助的な棚16,17は、棚15に物品を載置する際に、フォークリフトのフォークなどを差し込んでドライブインラック2から除き、適宜の仮置き場所などに仮置きしておく。そして棚16の使用時には、図3の棚14の位置にフォークリフトなどで搬送して、レール10,11やピン50とフィットするようにフォークで下ろしてセットする。棚17の使用時には、図3の棚15の位置にセットする。
【0020】
実施例の動作を示す。物品を収納する場合、床上に2段にパレット19を積むと、その上部の棚にフォークリフトなどでパレット19を例えば2段に積む。次に物品を載置する棚を、手前側から奧側へ、フォークリフトのフォークの根元部分の上部などで、押してスライドさせる。以下同様に、床上にパレットを載置し、次いで棚上に載置し、空き棚をスライドさせて、作業スペースを移動させる。物品を出庫する場合、床上の物品と棚上の物品を上下4段分(上面視で1棚分の物品)出庫すると、空きになった棚をフォークリフトのフォークなどで引いて手前側にスライドさせる。このため、入出庫作業の位置に応じて作業スペースの位置を移動させることができる。また棚には幅方向に複数の物品を並置できるので、ドライブインラック2の収納効率を改善でき、またフォークリフトなどで一括して複数物品を入出庫できるので、入出庫が効率的である。
【0021】
棚は、走行ユニット24の車輪28がL字鋼22上を走行するので、幅方向にずれることがない。また棚に物品からの荷重が加わると、バネ36,40が圧縮され、棒状部材32が沈みこんで、ブレーキ片30により車輪28が固定されるので、物品を載せた棚が妄動することはない。また棚に物品からの荷重が加わると、バネ36,40が圧縮されて、プレート54がピン50に嵌合し、支持壁と棚とがより緊密に固定され、支持壁4,6が物品の荷重で傾いたりすることを防止できる。そして空き棚になると、自動的にロックが外れてスライド自在になり、またピン50との嵌合が外れる。
【0022】
【実施例2】
図4〜図6に第2の実施例を示し、図1〜図3と同じ符号は同じものを表し、100を加えた符号で、図1〜図3に類似のものがある場合は、同等のものを表す。また図1〜図3の実施例に関する説明は、特に断らない限り、図4〜図6の実施例にもそのまま当てはまる。図4〜図6において、102はドライブインラックで、104,106は支持壁で、108はその支柱である。110,111はレールで、ドライブインラック102の奥行き方向に平行に支持壁104,106に設置し、112はスライド自在の棚で、例えばフォーク差し込み孔114を備えている。120はフック122の取付部材で、棚112の左右に一対設け、124はH型鋼などからなる長尺部材で、レール110,111と平行に支持壁104,106に設ける。
【0023】
図6に示すように、レール110にはL字鋼22を設けて、走行ユニット24を走行させ、レール111には走行ユニット26を走行させ、何れも棚112に荷重が加わると、走行ユニットと棚本体との間のバネが圧縮されて、棚112が沈み込む。棚112が沈み込むと、走行ユニット24では、車輪がL字鋼22にロックされ、またフック122が下降して、長尺部材124にはまり、支持壁104,106が棚112により連結される。
【0024】
この結果、図4〜図6の実施例でも、ドライブインラックの収納効率の改善、入出庫作業の効率化、物品を載置した棚の妄動の禁止と、物品の荷重による支持壁の変形の防止を行うことができる。
【0025】
図4〜図6の実施例で、例えば長尺部材124とフック122との間の摩擦を大きくすると、フック122が長尺部材124に係合した際に、その間の摩擦力で棚112をロックしてスライドを禁止できる。このように、弾性体の変形による棚のロックは、車輪をロックするものには限らない。また弾性体の変形を用いず、レール上の所定の位置毎に、棚をロックするための凹部などをレールに設け、所定の位置まで棚をスライドさせると、車輪が凹部にはまって妄動しないようにし、再度スライドさせる場合、空き棚を僅かに持ち上げ気味に押し引きして移動させても良い。棚は、簡単にスライドできるようにするため、レール上を走行させたが、スライドの機構自体は任意である。

[Field of the Invention]
The present invention relates to a drive rack in which a loading / unloading apparatus enters a rack to work.
[0002]
[Prior art]
Drive-in racks and drive-through racks are known as racks in which a loading / unloading device such as a forklift enters a rack and loads and unloads articles in units such as pallets. When these racks are collectively called a drive rack, the distance between the rack support wall and the support wall is approximately one pallet, and the left and right ends of the pallet are placed on the shelf supports provided on the left and right support walls, respectively. And store articles in pallet units. Therefore, a plurality of articles cannot be juxtaposed in a direction substantially perpendicular to the support wall (hereinafter referred to as “width direction”). The storage space for the articles between the support walls also serves as a space for a forklift or the like to work. In addition, one pallet is placed for each shelf holder, or two tiers are stacked one above the other, and in addition to direct placement on the floor, about one to three shelves are provided to store articles on a pallet basis. store.
[0003]
However, in such a drive rack, a plurality of articles cannot be juxtaposed in the width direction between the support walls and the support efficiency of the articles is limited. In addition, it is not possible to use a loading / unloading apparatus that can load and unload a plurality of articles, and there is a limit to the efficiency of loading and unloading.
[0004]
[Problems of the Invention]
The basic problem of the present invention is that it is possible to store a plurality of articles along the width direction of the drive rack, to secure a work space for the loading / unloading apparatus, and to further increase the load from the articles. This is to prevent the support wall from being inclined .
An additional problem in the invention of claim 2 is that the shelf can be easily slidable and the shelf can be locked to prevent the shelf from being reluctant.
An additional problem of the invention of claim 3 is that the shelf can be automatically locked when an article is loaded.
[0005]
[Structure of the invention]
In the drive rack in which the space between the support wall and the support wall is used as a storage space for goods used as a work space of the loading / unloading device, the support wall is provided so as to span between the support wall and the support wall. A slidable shelf is provided, and a plurality of articles can be placed on the shelf along a direction substantially perpendicular to the support wall, and the shelf slide forms a work space for the loading / unloading device in the drive rack. In addition, a fitting portion that sinks downward when a load is applied to the shelf and fits to the support wall is provided on the shelf, and the fitting is provided along a direction perpendicular to the support wall. The relative position between the shelf and the support wall is regulated (claim 1).
[0006]
Preferably, a rail is provided on the support wall, a wheel is provided on the shelf, and the shelf is slid by running the shelf along the rail, and lock means for prohibiting the shelf from running. (Claim 2).
[0007]
Particularly preferably, an elastic body that is deformed by a load applied from an article to the shelf is provided between the wheel and the shelf, and the locking means is configured to lock the shelf to the rail with a lock piece by deformation of the elastic body. (Claim 3).
[0008]
[Operation and effect of the invention]
In the present invention, since a shelf that is slidable along the support wall is provided between the support walls of the drive rack, a plurality of articles are placed on the shelf in the direction between the support wall and the support wall (width direction). ). Next, since the shelf is slidable along the support wall, it is possible to secure a work space for the loading / unloading apparatus to work by sliding the unnecessary shelf. Therefore, the storage efficiency of the drive rack can be improved, and a loading / unloading apparatus that can load and unload a plurality of articles can be used at the same time, so that the loading / unloading efficiency of the drive rack can be improved. Further, by providing the shelf with a fitting portion that sinks downward when a load is applied to the shelf and engages the support wall, the shelf and the support wall are more tightly fixed by the load of the article, and the support wall becomes the article. It is possible to prevent tilting due to the load from.
[0009]
In the invention of claim 2, since the rail is installed on the support wall and the wheels of the shelf are driven by this rail, the shelf can be easily slid. And since the locking means for prohibiting the traveling of the shelf is provided, it is possible to prevent the shelf from reluctance.
[0010]
In the invention of claim 3, the elastic body is deformed by the load of the article applied to the shelf, and the shelf can be automatically locked by this deformation.
[0011]
【Example】
1 to 3 show a drive-in rack according to an embodiment. Although the embodiment takes a drive-in rack as an example, the same applies to a drive-through rack. Further, the depth direction and the width direction of the drive-in rack 2 are determined as shown in FIG. 3, and a storage device such as a forklift enters the space between the support walls 4 and 6 from the front of the depth direction to enter and exit. To do. Although the support walls 4 and 6 are shown one by one in the drawing, a plurality of these may be provided and a plurality of drive-in racks 2 of the embodiment may be juxtaposed. Further, the figure shows an example in which one layer of shelves 12 to 17 is provided, and the pallet 19 is stored in two levels on the floor and two levels in the shelves 12 to 17 in total, but the support walls 4 and 6 are vertically arranged. A plurality of shelves may be provided by extending.
[0012]
Reference numeral 8 denotes a support column of support walls 4 and 6, and rails 10 and 11 are installed on the support walls 4 and 6 in parallel to the depth direction so that the shelves 12 to 17 can be slidably mounted. However, the most shelf 12 is fixed and does not slide, and the nearest shelves 16 and 17 are auxiliary shelves and may not be provided. For example, the articles 18 may be stacked on a pallet 19 to be loaded / unloaded and stored, and the pallet 19 and the article 18 above the pallet 19 may be simply referred to as an article.
[0013]
By making the shelves 12 to 17 slidable, a work space 20 for two shelves is provided so that there are no shelves in the work space 20 so that articles can be loaded and unloaded with a forklift or the like. To do. The position of the work space 20 can be freely moved by sliding the shelf. The forklift is of a type that can store and transport a plurality of pallets (here, two pallets) in a batch.
[0014]
Although the structure of the shelf 13 is shown in FIG. 2, this structure is the same also in other shelves. An L-shaped steel 22 is attached to the upper surface of the rail 10 among the rails 10 and 11. In the traveling unit 24 corresponding to the rail 10, the wheel 28 is provided, and a brake piece 30 for locking the wheel 28 and a load for receiving the load from the shelf 13 are attached to the rod-like member 32 for mounting the traveling unit 24. A contact portion 34 is provided, and an elastic body such as a spring 36 is disposed between the contact portion 34 and the wheel frame 37 and is deformed by a load applied to the shelf. For this reason, when the pallet is placed on the shelf, the spring 36 is compressed, the brake piece 30 sinks, the wheel 28 is locked, and the wheel 28 is fixed to the L-shaped steel 22. A solid line in FIG. 2 indicates a position when an article load is applied to the shelf 13, and a chain line indicates a position when the shelf 13 is lifted without applying a load. Here, although the running of the shelf 13 is prohibited by the brake piece 30 that abuts on the wheel 28, the present invention is not limited to this. For example, the elastic body may be deformed by a load applied to the shelf, and the shelf itself may be engaged with the rail, thereby prohibiting the shelf from traveling. As an example of this, when a frame body having a C-shaped cross section is suspended from a shelf via an elastic body so that both sides of the C shape straddle a rail having a triangular cross section, and the shelf is lowered by a load, There is a configuration in which the frame body is engaged with the rail.
[0015]
In the traveling unit 26 on the rail 11 side, for example, a wheel 29 having a flat contact surface with the rail is used, a rod-like member 42 is attached to the wheel frame 37, and an abutting member 44 is disposed freely on the upper part thereof to abut. A spring 44 is disposed between the contact member 44 and the wheel frame 37 under the load of the shelf 13 by the member 44. When the spring 40 is compressed, the tip of the rod-shaped member 42 is accommodated in the hole 46.
[0016]
Here, for the sake of simplicity, means for locking the wheel is provided only on the traveling unit 24 on one side, and the L-shaped steel 22 is provided only on the rail 10 on one side, but the traveling unit with locking means on both sides of the shelf. A rail 10 with 24 and L-shaped steel 22 may be provided. Moreover, when the L-shaped steel 22 is used, the position of the shelf along the width direction can be regulated, but instead of the L-shaped steel 22, a T-shaped steel is used upside down and combined with a wheel having an H-shaped cross section. Also, the position of the shelf in the width direction can be regulated.
[0017]
The support walls 4 and 6 are combined using the shelves 12 to 17. A pin 50 is provided on the support walls 4 and 6 through a mounting member 52 at a position such as the column 8, and the pin 50 is oriented in parallel to the rails 10 and 11. The plate 54 of the shelves 12 to 17 is provided with a guide groove 56 and a fitting portion 58 that communicates with the guide groove 56. When no load is applied to the shelves 12 to 17, the pin 50 is located at the height position of the guide groove 56. When the load is applied to the shelves 12 to 17 and the shelves 12 to 17 are depressed by the springs 36 and 40, the pin 50 appears at the height position of the fitting portion 58.
[0018]
As shown in FIG. 3, the most shelf 12 is provided with plates 54 at both left and right ends so that the pins 50 can be fitted to both ends. In the other shelves 13 to 15, a plate 54 is provided on either the left or right side so that the plate 50 can be freely fitted, and the position where the plate is provided is switched between the left and right for each shelf. When the work space 20 is two shelves and the shelf 13 is vacated and retracted, the work space 20 slides to the position of the shelf 13b indicated by the chain line, and at this position, the pin 50 may or may not be engaged. . Further, the slide range of the shelf 14 is from the position in FIG. 3 to the position on the near side of the shelf 13, and the slide range of the shelf 15 is from the position in FIG. 3 to the position of the shelf 13b.
[0019]
The auxiliary shelves 16 and 17 on the shelf 15 are temporarily placed in an appropriate temporary place or the like when a fork of a forklift is inserted and removed from the drive-in rack 2 when an article is placed on the shelf 15. . When the shelf 16 is used, it is transported to the position of the shelf 14 in FIG. 3 by a forklift or the like and is lowered and set with the fork so as to fit the rails 10 and 11 and the pins 50. When the shelf 17 is used, it is set at the position of the shelf 15 in FIG.
[0020]
The operation of the embodiment will be described. When storing articles, when the pallets 19 are stacked in two stages on the floor, the pallets 19 are stacked in, for example, two stages on a shelf above the floor by a forklift or the like. Next, the shelf on which the article is placed is pushed and slid from the front side to the heel side with the upper part of the base portion of the fork of the forklift. Similarly, the pallet is placed on the floor, then placed on the shelf, the empty shelf is slid, and the work space is moved. When goods are delivered, if the goods on the floor and the goods on the shelf are delivered up and down four stages (one shelf in top view), the empty shelf is pulled with a fork of a forklift and slid to the near side. . For this reason, the position of the work space can be moved according to the position of the loading / unloading work. Further, since a plurality of articles can be juxtaposed in the width direction on the shelf, the storage efficiency of the drive-in rack 2 can be improved, and a plurality of articles can be loaded and unloaded in a lump with a forklift or the like, so that loading and unloading is efficient.
[0021]
Since the wheel 28 of the traveling unit 24 travels on the L-shaped steel 22, the shelf does not shift in the width direction. Further, when a load from the article is applied to the shelf, the springs 36 and 40 are compressed, the rod-like member 32 sinks, and the wheel 28 is fixed by the brake piece 30, so that the shelf on which the article is placed does not move. . Further, when a load from the article is applied to the shelf, the springs 36 and 40 are compressed, the plate 54 is fitted to the pin 50, the support wall and the shelf are more closely fixed, and the support walls 4 and 6 are attached to the article. It can be prevented from tilting with a load. When the shelf becomes empty, it is automatically unlocked and slidable, and the fitting with the pin 50 is released.
[0022]
[Example 2]
4 to 6 show a second embodiment, the same reference numerals as those in FIGS. 1 to 3 represent the same elements, and the reference numerals with 100 added are similar to those in FIGS. Represents things. The description of the embodiment of FIGS. 1 to 3 applies to the embodiment of FIGS. 4 to 6 as it is unless otherwise specified. 4 to 6, reference numeral 102 denotes a drive-in rack, reference numerals 104 and 106 denote support walls, and reference numeral 108 denotes a support column. Reference numerals 110 and 111 denote rails, which are installed on the support walls 104 and 106 in parallel with the depth direction of the drive-in rack 102. Reference numeral 112 denotes a slidable shelf having a fork insertion hole 114, for example. A pair of mounting members 120 are provided on the left and right sides of the shelf 112, and a long member 124 is formed of H-shaped steel or the like and is provided on the support walls 104 and 106 in parallel with the rails 110 and 111.
[0023]
As shown in FIG. 6, the rail 110 is provided with an L-shaped steel 22 to cause the traveling unit 24 to travel, the rail 111 to travel the traveling unit 26, and when any load is applied to the shelf 112, The spring between the shelf body is compressed and the shelf 112 sinks. When the shelf 112 sinks, in the traveling unit 24, the wheel is locked to the L-shaped steel 22, and the hook 122 is lowered to fit into the long member 124, and the support walls 104 and 106 are connected by the shelf 112.
[0024]
As a result, also in the embodiment of FIGS. 4 to 6, improvement in storage efficiency of the drive-in rack, efficiency of the loading / unloading work, prohibition of the detachment of the shelf on which the article is placed, and deformation of the support wall due to the load of the article Prevention can be performed.
[0025]
4 to 6, for example, when the friction between the long member 124 and the hook 122 is increased, when the hook 122 engages with the long member 124, the shelf 112 is locked by the frictional force therebetween. You can ban sliding. Thus, the shelf lock due to the deformation of the elastic body is not limited to locking the wheels. Also, if the rail is provided with a recess for locking the shelf at every predetermined position on the rail without using deformation of the elastic body, and the shelf is slid to the predetermined position, the wheel will not get stuck in the recess and move around In the case of sliding again, the empty shelf may be lifted slightly and pushed and pulled slightly. The shelves were run on rails so that they could slide easily, but the sliding mechanism itself is arbitrary.
