As described in Japanese Patent No. 405, it is equipped with an article depositing / dispensing body that puts an article in and out of each storage shelf of a storage rack installed in a warehouse. Further, at a predetermined position near the storage rack, an article carry-in position for carrying in the article conveyed from the previous step (for example, a processing step) to the storage rack and an article taken out from the storage rack to a subsequent step (for example, an assembly step). It is also generally known that an article unloading position for unloading is set, and the article delivering / receiving body is configured to deliver the article at these article loading / unloading positions.

[0003]

By the way, a defective article may be found in the articles stored in the storage rack. When a defective article is found, there is a request to take out such a defective article in advance without sending it to a subsequent process. Further, there is a case where a sampling inspection is performed, and conventionally, a method of extracting a predetermined number of articles sent to a post-process has been adopted, but such a sampling inspection is not performed in the post-process. It would be convenient if the articles stored in the storage rack could be directly taken out.

In the conventional automated warehouse, it is not configured to exclusively take out a predetermined article such as a defective article from the storage rack. To take out such a predetermined article, the article must be removed. There was no choice but to transfer to the article carry-in position or the article carry-out position and take out there. However, the article carry-in / carry-out position is not always set to a position suitable for taking out the article, and the article carry-in / carry-out position is usually used to transfer the article to / from the article delivery / reception body. Although devices are provided, these devices are generally not configured to facilitate the removal of articles, and thus it was generally difficult to remove articles at the article load / unload positions. On the other hand, if the delivery device or the like is improved so that the articles can be easily taken out, or if a new apparatus for exclusively taking out the articles is newly installed, a problem such as a large increase in cost occurs. .

The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to easily take out a predetermined article stored in a storage rack by using an existing device without sending it to a subsequent process. The purpose is to provide an automated warehouse.

[0006]

In order to achieve the above object, according to the present invention, a take-out shelf for taking out articles is provided at a predetermined position of a storage rack, which can transfer predetermined articles by an article depositing / dispensing body. .

That is, the automatic warehouse according to the first aspect of the present invention is the automatic warehouse comprising an article depositing / removing body which is movable along a storage rack having a plurality of storage shelves and takes in and out articles from the storage shelves. The storage rack is provided with a take-out shelf for taking out the predetermined article stored in the storage rack at a position where the article storage body can transfer the predetermined article from the storage rack. And

According to the second aspect of the present invention, in addition to the configuration of the automatic warehouse according to the first aspect, the take-out shelf is provided with the articles transferred to the take-out shelf on the back of the storage rack. It is characterized in that it can be taken out from.

[0009]

In the automated warehouse according to the present invention having the above-described structure, predetermined articles such as defective articles and extracted articles stored in the storage rack of the storage rack are transferred to the extraction rack by the article delivery body. People take it out from there.

As shown in the above configuration, the take-out shelf is provided at a predetermined position of the storage rack where the predetermined articles stored in the storage rack can be transferred by the article delivery body. By this, it is possible to transfer from the storage rack to the take-out rack, and it is possible to easily take out a predetermined article from there. Therefore, it is not necessary to add a special improvement to the existing device or install a new device for taking out the article. As described above, according to the automated warehouse of the present invention, it is possible to easily take out a predetermined article stored in the storage rack by using the existing device without sending it to the subsequent process.

Further, according to the automatic warehouse of the second aspect, since the articles transferred to the take-out shelf can be taken out from the back of the storage rack, the predetermined articles can be taken out without hindering the movement of the article depositing / dispensing body. It can be done safely.
