った。(Disadvantages of the Prior Art) The conventional stacker crane for automated warehouses has the following disadvantages. In other words, since only one article can be placed on the lifting platform of the stacker crane, the stacker crane picks up 1 (!l) articles at the carry-in stage and places them on the article storage shelf of the rack. After storing the first item, it is necessary to repeat the process of moving it to the carry-in stage to pick it up, and also to transfer the goods taken out from the goods storage shelf to the carry-out stage. After that, in order to carry out the articles in the separate article storage shelves, it is necessary to move from the unloading station to the article storage shelves again, which is a drawback.In other words, the operating efficiency of the stacker crane is actually poor. There was a drawback.

However, Japanese Patent Application Laid-open No. 1-172,121--Japanese Patent Application Laid-open No. 59-2
It is provided so that it can freely protrude horizontally in either the front or rear direction using a known advance/retreat mechanism as disclosed in Japanese Patent No. 3°762. An article transfer conveyor 16 is provided on the upper surface of the slide fork 15 and can be driven in forward and reverse directions with the conveyance direction left and right. This article transfer conveyor 16 lifts and lowers the article W by protruding the article W downward by protruding the slide fork 15, lifting the article W by raising the lifting table 12, and retracting it to the lifting table 12 side. The article W can be pulled into the stand 12 and lowered onto the article storage shelf 2 or the like by performing the reverse operation to the above. Note that the conveyance surface of the article transfer conveyor 16 and the conveyance surface of the article storage conveyor 14 are flush with each other.
（実施例の作用） 次に実施例倉庫の作用を説明する。(Effect of Example) Next, the operation of the warehouse according to the embodiment will be explained.
まず、物品収納棚２に収納された物品Ｗを搬出ステーシ
ョン（図示節）に搬出する方法について説明する。First, a method for carrying out the articles W stored in the article storage shelf 2 to the carry-out station (as shown) will be explained.

物品Ｗや他方の物品移載コンベアエ６上の物品Ｗを順次
１個づつ移載しては搬出ステーションに降ろして行く。After the article W is drawn into the lifting platform 12 by the article transfer conveyor 6 (slide fork 15) which is closer to the article storage shelf 2 where the article W to be taken out is stored, the article transfer conveyor 6 and article storage conveyor 14 is driven to transfer the article W onto the article storage conveyor 14. Note that when a plurality of articles W can be placed on the article storage conveyor 14, this action is repeated until the article storage conveyor 14 is full of articles W. In this way, the article transfer conveyors 1.6 are located on the left and right. Therefore, the article transfer conveyor 16 closer to the article storage shelf 2 containing the article W to be taken out can be used, so that the stacker crane 10 can be moved laterally and efficiently. When the article storage conveyor 14 is full, articles W are also placed on the left and right article transfer conveyors 16. Thereafter, the stacker crane IO is transported to the unloading stage, where the articles W placed on the article transfer conveyor 16 closest to the unloading stage are first unloaded to the unloading station, and then the empty The articles W on the article storage conveyor 14 and the articles W on the other article transfer conveyor 6 are sequentially transferred one by one onto the transferred article transfer conveyor 16 and unloaded to the carry-out station.
なお、前記と逆の順序によって、搬入ステージ、ンから
物品Ｗを物品収納棚２に収納することが出来る。Note that the articles W can be stored in the article storage shelf 2 from the carry-in stage through the reverse order.
（発明の効果）
この発明は、前記の如き構成によって、以下の如き効果
を奏する。(Effects of the Invention) With the above-described configuration, the present invention provides the following effects.
