JP-A-5-338711 JP-A-1-122806

また、スタッカクレーンによって荷物を搬送する従来の立体倉庫の概略図を図７に示し、同図中、ａはスタッカクレーン、ｂは該スタッカクレーンの走路、ｃは該走路の両側に設けられた多段の保管棚、ｄは荷物である。該スタッカクレーンａは、周知のように、マストｅに沿って昇降台ｆが垂直に昇降動するように構成され、該昇降台ｆにはシャトル（フォークアームとも称される）ｇが両側の保管棚に向けて水平に進退動し得るように設けられ、該シャトルｇに乗載された荷物ｄを該シャトルｇの進退動と昇降台ｆの昇降動によって所定の保管棚上に搬入・搬出できるようにしたものである。 FIG. 7 shows a schematic diagram of a conventional three-dimensional warehouse for transporting cargo by a stacker crane, in which a is a stacker crane, b is a runway of the stacker crane, and c is a multi-stage provided on both sides of the runway. The storage shelf d is a luggage. As is well known, the stacker crane a is configured such that a lifting platform f vertically moves along a mast e, and a shuttle (also referred to as a fork arm) g is stored on both sides of the lifting platform f. It is provided so as to be able to move forward and backward horizontally toward the shelf, and the load d mounted on the shuttle g can be carried in and out of a predetermined storage shelf by the forward and backward movement of the shuttle g and the vertical movement of the lift platform f. It is what I did.

ところで、従来のスタッカクレーンは、一般にシャトルｇ上に１棚分の荷物（図示した場合は４塊分）を乗載し、保管棚上に搬入・搬出させるものであった。このため、該スタッカクレーンの走路幅ｗは保管棚の奥行きｈと略々同じであることを要するものであった。そしてこのように広い走路幅ｗを要することが、収納効率の妨げになり、省スペースで多くの荷物が収容できることを指命とする立体倉庫としての性能を低下させている要因であった。
そこで本発明は、走路幅が狭められ、限られたスペースにより多くの荷物を収容できる立体倉庫を提供しようとするものである。 By the way, a conventional stacker crane generally loads one shelf of luggage (four in the illustrated case) on the shuttle g, and loads and unloads it on a storage shelf. For this reason, the running path width w of the stacker crane is required to be substantially the same as the depth h of the storage shelf. In addition, such a wide runway width w hinders the storage efficiency, and is a factor that deteriorates the performance as a three-dimensional warehouse that is required to store a large amount of luggage in a space-saving manner.
Therefore, the present invention intends to provide a three-dimensional warehouse in which the traveling road width is narrowed and a large amount of luggage can be accommodated in a limited space.

そこで本発明に係る立体倉庫は、スタッカクレーンの走路の両側に保管棚が多段に設けられ、該スタッカクレーンの昇降フレームに設けられたシャトルを両側の該保管棚に向けて水平に進退動させることによって荷物が搬入・搬出されるようにした立体倉庫において、保管棚の奥行きを少なくとも２塊の荷物を前部と奥部とに並べて保管し得る寸法に設定するとともに、昇降フレームに夫々独立して作動し得るシャトルを上下２段に設け、そのうちの少なくとも１つのシャトルは荷物を保管棚の奥部に搬入・搬出し得る進退動ストロークを備えていることを特徴とする。 Therefore, in the three-dimensional warehouse according to the present invention, storage shelves are provided in multiple stages on both sides of the stacker crane runway, and the shuttle provided on the lifting frame of the stacker crane is moved forward and backward horizontally toward the storage shelves on both sides. In a three-dimensional warehouse in which luggage is carried in and out by the storage rack, the depth of the storage shelf is set to a dimension that allows storage of at least two pieces of luggage arranged side by side in the front and back, and independent of the lifting frame. Shuttles that can be operated are provided in two upper and lower stages, and at least one of the shuttles has an advancing / retreating stroke that allows loading and unloading of luggage to the back of the storage shelf.

また本発明に係る立体倉庫は、スタッカクレーンの走路の両側に多段の保管棚が設けられ、該スタッカクレーンの昇降フレームに設けられたシャトルを両側の該保管棚に向けて水平に進退動させることによって荷物が搬入・搬出されるようにした立体倉庫において、保管棚の奥行きを少なくとも３塊の荷物を前部と真中部と奥部にわたり並べて保管し得る寸法に設定するとともに、昇降フレームに夫々独立して作動し得るシャトルを上下３段に設け、そのうちの少なくとも１つのシャトルは荷物を保管棚の奥部に搬入・搬出し得る進退動ストロークを備え、他の少なくとも１つのシャトルは荷物を保管棚の真中部に搬入・搬出し得る進退動ストロークを備えていることを特徴とする。 The three-dimensional warehouse according to the present invention is provided with multistage storage shelves on both sides of the stacker crane runway, and the shuttle provided on the lifting frame of the stacker crane is moved forward and backward horizontally toward the storage shelves on both sides. In a three-dimensional warehouse in which luggage is carried in and out by the storage, the depth of the storage shelf is set to a size that allows storage of at least three pieces of luggage arranged side by side across the front, middle, and back, and independent of the lifting frame. Shuttles that can be operated in the upper and lower stages are provided, at least one of which has an advancing / retreating stroke that allows loading and unloading of luggage into the back of the storage shelf, and at least one other shuttle stores luggage in the storage shelf It is characterized by having an advancing / retreating stroke that can be carried in and out in the middle of the.

スタッカクレーンの走路幅が保管棚の奥行きほど要しなくなり、該走路幅を狭くできることから、省スペースでより多くの荷物が収容できるようになり、立体倉庫の収納効率を大幅に向上させる。 Since the width of the stacker crane is not required as much as the depth of the storage shelf, and the width of the track can be narrowed, more luggage can be accommodated in a small space, and the storage efficiency of the three-dimensional warehouse is greatly improved.

次に請求項１に記載した発明の実施例を棒状鋼材を保管する立体倉庫について図面とともに説明する。図１はこの立体倉庫の概略を示す水平断面平面図、図２はそのＡ−Ａ線断面側面図、図３はＢ−Ｂ線断面側面図である。図中、１ａ，１ｂはスタッカクレーン、２ａ，２ｂは該スタッカクレーンを矢印の方向に往復走行させるため床面および天井面にレール３が敷設された走路、４ａ，４ｂは該走路の両側に設けられた多段の保管棚、５は複数本の棒状鋼材を一束に結束してなる長尺の荷物である。スタッカクレーン１ａ，１ｂは車輪６を備えた台車７の垂直マスト１３に沿って昇降動するように昇降フレーム８が設けられたもので、１２は該昇降フレーム８のガイドローラである。なお、台車７の走行駆動源であるモータ、及び昇降フレーム８の昇降駆動源であるモータ等は図示省略する。なお、保管棚４ａ，４ｂの奥行きＨは、図示したように４塊の荷物５を２塊を一つとして前部と奥部に並べて保管し得る寸法に設定される。また、スタッカクレーン１ａ，１ｂの走路幅Ｗは該奥行きＨの約半分に設定される。 Next, an embodiment of the invention described in claim 1 will be described with reference to a three-dimensional warehouse for storing rod-shaped steel materials. FIG. 1 is a horizontal sectional plan view schematically showing the three-dimensional warehouse, FIG. 2 is a sectional side view taken along the line AA, and FIG. 3 is a sectional side view taken along the line BB. In the figure, 1a and 1b are stacker cranes, 2a and 2b are runways in which rails 3 are laid on the floor and ceiling surfaces in order to reciprocate the stacker cranes in the direction of the arrows, and 4a and 4b are provided on both sides of the runways. The multi-stage storage shelves 5 are long packages formed by bundling a plurality of bar-shaped steel materials into one bundle. The stacker cranes 1 a and 1 b are provided with a lifting frame 8 so as to move up and down along a vertical mast 13 of a carriage 7 having wheels 6, and 12 is a guide roller for the lifting frame 8. Note that a motor that is a travel drive source of the carriage 7 and a motor that is a lift drive source of the lift frame 8 are not shown. In addition, the depth H of the storage shelves 4a and 4b is set to a size that allows the four packages 5 to be stored side by side in the front portion and the back portion, as shown in the drawing. Further, the travel path width W of the stacker cranes 1a and 1b is set to about half of the depth H.

また、スタッカクレーン１ａ，１ｂの昇降フレーム８にはシャトル９とシャトル１０が上下２段に設けられる。該シャトル９およびシャトル１０は、夫々独立して水平に進出動（動力源は図示せず）し得るもので、いずれのシャトル上にも２塊の荷物５を載置し得る。そして一方のシャトル９は該荷物５を両側の保管棚の前部上に移送し得る進退動ストローク（以下、「シングルリーチシャトル」という）を備えているのに対し、他方のシャトル１０は該荷物５を両側の保管棚の奥部上まで移送し得る進退動ストローク（以下、「ダブルリーチシャトル」という）を備えたものである。 Further, a shuttle 9 and a shuttle 10 are provided in two stages on the lifting frame 8 of the stacker cranes 1a and 1b. The shuttle 9 and the shuttle 10 can move horizontally (the power source is not shown) independently, and two packages 5 can be placed on either shuttle. One shuttle 9 has an advancing / retreating stroke (hereinafter referred to as “single reach shuttle”) capable of transferring the cargo 5 onto the front part of the storage shelves on both sides, whereas the other shuttle 10 is provided with the cargo. 5 is provided with an advancing / retreating stroke (hereinafter referred to as “double reach shuttle”) capable of transferring 5 to the back of the storage shelves on both sides.

このため、例えば図３に示した保管棚４ｂ′上に荷物５を搬入するに際しては、シャトル９上およびシャトル１０上に荷物５を２塊宛載置して台車６を走行させ該保管棚４ｂ′の前面で該台車７を停止させるとともに、昇降フレーム８を昇降動し、シャトル１０の高さが該保管棚４ｂ′よりも少し高くなるように該昇降フレーム８を停止させた後、先ずシャトル１０を図４に示したように該保管棚の奥部まで進出させて該昇降フレーム８を少し下降させることにより該シャトル１０上の荷物５を該保管棚の奥部に移載し、該シャトル１０を後退させる。次いで図５に示したようにシャトル９の高さが該保管棚４ｂ′よりも少し高くなるように該昇降フレーム８を下降させて停止するとともに該シャトル９を該保管棚４ｂ′の前部に進出させて該昇降フレーム８を少し下降させることにより、該シャトル９上の荷物５を該保管棚４ｂ′の前部に移載する。これを繰り返すことにより各保管棚４ｂ上に荷物を４塊搬入し保管することができる。また、シャトル９，１０を保管棚４ａ上に進退動させることにより各保管棚４ａ上にも同様に荷物を４塊搬入し保管することができる。
なお、上記において、シャトル９はシングルリーチシャトルで説明したが、ダブルリーチシャトルであってもよい。 For this reason, for example, when loading the cargo 5 onto the storage shelf 4b 'shown in FIG. 3, two packages 5 are placed on the shuttle 9 and the shuttle 10 and the carriage 6 is caused to travel so that the storage shelf 4b. First, the carriage 7 is stopped at the front surface of ′, the elevator frame 8 is moved up and down, and the elevator frame 8 is stopped so that the height of the shuttle 10 is slightly higher than the storage shelf 4b ′. As shown in FIG. 4, as shown in FIG. 4, the cargo 5 on the shuttle 10 is transferred to the inner part of the storage shelf by moving the elevator frame 8 to the inner part of the storage shelf and lowering the lifting frame 8 slightly. Move 10 back. Next, as shown in FIG. 5, the elevating frame 8 is lowered and stopped so that the height of the shuttle 9 is slightly higher than the storage shelf 4b ', and the shuttle 9 is placed at the front of the storage shelf 4b'. The cargo 5 on the shuttle 9 is transferred to the front portion of the storage shelf 4b ′ by moving forward and lowering the lifting frame 8 slightly. By repeating this, four packages can be loaded and stored on each storage shelf 4b. Further, by moving the shuttles 9 and 10 forward and backward on the storage shelves 4a, it is possible to similarly carry and store four packages on each storage shelf 4a.
In the above description, the shuttle 9 has been described as a single reach shuttle, but may be a double reach shuttle.

また、保管棚４ａ，４ｂ上に保管された４塊の荷物を搬出するに際しては、先ずシャトル９を該保管棚の少し下側に進出させた後、昇降フレーム８を少し上昇させることにより該保管棚の前部の２塊の荷物５を該シャトル９上に移載し該シャトル９を昇降フレーム８内に収縮させる。次いでシャトル１０を該保管棚の少し下側で奥部まで進出させ昇降フレーム８を少し上昇させることにより該保管棚の奥部の２塊の荷物５を該シャトル１０上に移載し該シャトル１０を昇降フレーム８内に収縮させる。そして台車６を走行させれば所望の荷物を搬出できる。なお、一旦はシャトル９上に移載した荷物を保管棚上に戻すことをすれば、奥部の荷物のみを搬出することも可能である。
このようにこの実施例では、独立して作動し得るシャトル９，１０を上下２段に設けたことから、スタッカクレーン１ａ，１ｂの走路幅Ｗが保管棚の奥行きＨの約半分でよくなり、収容効率が向上する。なお、この実施例では４塊の荷物を２塊を一つとして搬入・搬出するようにしたが、保管棚の前部と奥部に１つずつ荷物を搬入・搬出する形態としてもよいことは言うまでもない。 When carrying out the four packages stored on the storage shelves 4a and 4b, the shuttle 9 is first advanced slightly below the storage shelf, and then the elevator frame 8 is slightly lifted to slightly lower the storage. The two packages 5 at the front of the shelf are transferred onto the shuttle 9 and the shuttle 9 is contracted into the lifting frame 8. Next, the shuttle 10 is advanced to the back slightly below the storage shelf and the lifting frame 8 is slightly lifted to transfer the two packages 5 at the back of the storage shelf onto the shuttle 10. Is contracted into the lifting frame 8. And if a cart 6 is made to run, a desired load can be carried out. Note that it is also possible to carry out only the back luggage once the luggage transferred on the shuttle 9 is returned to the storage shelf.
Thus, in this embodiment, since the shuttles 9 and 10 that can operate independently are provided in two upper and lower stages, the running path width W of the stacker cranes 1a and 1b can be about half the depth H of the storage shelf, Containment efficiency is improved. In this embodiment, four packages are carried in and out as two packages, but it is also possible to carry in and out one package at the front and back of the storage shelf. Needless to say.

一方、図６は請求項２に記載した立体倉庫の実施例を示すものである。この実施例では保管棚４ａ，４ｂの奥行きを少なくとも３塊の荷物５を前部と真中部と奥部にわたり並べて保管し得る寸法に設定するとともに、昇降フレーム８に夫々独立して作動し得るシャトル９，１０，１１を上下３段に設け、その少なくとも１つのシャトル１１は荷物を保管棚の奥部に搬入・搬出し得るように進退動ストロークを設定し、他の少なくとも１つのシャトル１０は荷物を保管棚の真中部に搬入・搬出し得るように進退動ストロークを設定している。従ってこの立体倉庫では、シャトル１１によって荷物を保管棚の奥部に搬入・搬出し、シャトル１０によって荷物を保管棚の真中部に搬入・搬出し、シャトル９によって荷物を保管棚の前部に搬入・搬出するようにすれば、図示したように走路幅Ｗを該保管棚の奥行きＨの約１／３に設定することができ、一層収容効率が向上する。
また、３塊の荷物５の搬入・搬出に適用する場合、特に３段シャトルの少なくとも一つの奥部に搬入・搬出が可能なシャトルは、ダブルリーチシャトルとすることが望ましいが、荷物が軽量である場合はトリプルリーチシャトルであっても良い。
更に、上記の説明は荷物を搬入・搬出する場合で行ったが、同じ保管棚にある２塊または３塊の荷物の位置を前後に入れ替える場合にもこの装置を適用することができる。 On the other hand, FIG. 6 shows an embodiment of the three-dimensional warehouse described in claim 2. In this embodiment, the depth of the storage shelves 4a and 4b is set to a size that allows at least three packages 5 to be stored side by side across the front, middle, and back, and the shuttle that can operate independently on the lifting frame 8 respectively. 9, 10 and 11 are provided in three upper and lower tiers, and at least one shuttle 11 has an advancing / retreating stroke so that the load can be carried in and out of the storage shelf, and at least one other shuttle 10 is loaded. The forward / backward stroke is set so that can be carried in and out of the middle of the storage shelf. Therefore, in this three-dimensional warehouse, the luggage is carried into and out of the storage shelf by the shuttle 11, the luggage is carried into and out of the middle of the storage shelf by the shuttle 10, and the luggage is carried by the shuttle 9 to the front of the storage shelf. -If it carries out, the runway width W can be set to about 1/3 of the depth H of this storage shelf as shown in figure, and the accommodation efficiency improves further.
In addition, when applied to loading / unloading of three packages 5, it is preferable that a shuttle capable of loading / unloading at least one back part of a three-stage shuttle is a double reach shuttle. In some cases, a triple reach shuttle may be used.
Furthermore, the above description has been given in the case of loading / unloading a package, but this apparatus can also be applied to the case where the positions of two or three packages on the same storage shelf are changed back and forth.
