BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a required article taken out from a storage article group of a storage facility in which articles are stored and stored, and stored in a collection container. The present invention relates to a transport device and a picking facility suitable for transporting and shipping while preventing collapse.

[0002]

2. Description of the Related Art In various factories and distribution centers,
Collecting containers (conveyed items) in which the required items are taken out from the storage shelves that store many types and many items
Since a work of storing the taken-out articles in the inside is performed, so-called picking equipment is provided, which is provided with a conveying device or the like that conveys the conveyed goods necessary for the work.

Various proposals have been made for this kind of conveying device and picking equipment. As proposals, there are JP-A-59-118601 and JP-A-59-18680.

[0004] In each of the transfer devices used in the equipment described in the above publications, the transfer surface is horizontal, so it is difficult to store the articles taken out from the storage equipment in the collection container. Moreover, there is a problem that the article falls over in the container, and the system as a whole cannot be picked efficiently and quickly. So, the fair fair 3-2448
Japanese Patent Laid-Open No. 3 proposes an "article handling device" which solves such a problem. In the apparatus, an article take-out surface is formed on one side surface of a storage section that is divided into multi-tiered multi-rows in which articles are stored, and the article take-out surface is provided in which the article take-out surface is divided into plural zones and There is provided a take-out display having a display for displaying the number of articles to be taken out for each zone, and a completion button whose display is cleared in response to a predetermined operation by an operator.
