Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article storage shelf provided with a plurality of article storage sections, a storage section into which articles to be stored are carried in from outside, and a storage section from which articles to be taken out are taken out. Is provided, between the article storage unit and the self in the article storage shelf, between the storage unit and the self, and
A loading / transporting section for loading / transporting articles to transfer articles between the exit section and the self, a loading section transfer position for the article storage section, a loading transfer position for the storage section, and The present invention also relates to an article storage facility configured to be changed to a transfer position for retrieval with respect to the retrieval section.

[0002]

2. Description of the Related Art Conventionally, in an article storage facility having the above-mentioned structure, as shown in, for example, Japanese Patent Laid-Open No. 4-347276, a parking lot 14a as a storage section is provided.
An exit parking room 14b as the exit section is provided one by one, and the elevator 1 with a conveyor as a loading / conveying section is provided.
In some cases, a vehicle, which is an example of an article, can be placed and transported between the vehicle 1 and the parking room 14a for entry and between the elevator 11 with a conveyor and the parking room 14b for exit.

[0003]

However, even in the above-mentioned conventional configuration, for example, the loading / transporting section transports an article (vehicle in the case of the above-mentioned configuration) (for example, an operation of storing the article in the article storage section).
In the case where a plurality of other articles are carried in at the same timing while executing, only one of the articles will wait in the parking lot for parking 14a, and the other article is It is necessary to wait outside the facility until the loading by the loading and transporting unit is completed and the entrance parking room 14a becomes empty. In such a case, the articles must be managed by a person, and work efficiency is reduced. There was a downside disadvantage. Also, in the case where the unloading operation by a person from the unloading section is not properly performed even though the unloading operation of the articles is continuously commanded, the articles already unloaded to the unloading section are unloaded. Until the next shipping work can not be done until
There was a disadvantage that the operation efficiency of the equipment was reduced.

[0004] In order to solve the above disadvantage, for example, it is conceivable to increase the number of the placement and conveyance units described above to a plurality of units. It is necessary to have a structure for placing and transporting articles between the equipment and the loading and unloading unit, so the equipment and moving space for moving the equipment are large, and the entire equipment becomes large and the cost is high. Disadvantages.

The present invention has been made in view of such a point, and an object of the present invention is to carry out loading / unloading of articles as efficiently as possible without enlarging the configuration of the entire equipment or incurring a significant increase in cost. An object of the present invention is to provide an article storage facility that can be executed.

[0006]

According to a feature configuration of the present invention, a plurality of articles, each of which can separately transfer articles to and from the placing / transporting section, are juxtaposed as the storage section. A plurality of articles that can be individually transferred between the storage section and the transfer section are arranged in parallel, and the storage section is any one of a plurality of storage transfer positions for the plurality of storage sections. The position can be selectively changed, and the position can be selectively changed to any of a plurality of transfer positions for retrieval with respect to the plurality of retrieval units.

Therefore, even when a plurality of articles are carried in at the same time, for example, when the loading / conveying section is performing an operation of storing articles toward the article storage section, the loading section is not required. Since a plurality of storage units capable of individually transferring articles are arranged in parallel with the transport unit, a plurality of articles can be sequentially carried into each of the plurality of storage units. Then, the placing and transporting section can cope by sequentially placing and transporting the articles carried into each of the storage sections and storing the articles in the corresponding article storage sections. Therefore, even if a plurality of articles are carried in at the same time, the person carrying each article does not need to wait outside the equipment.

[0008] Further, when a plurality of articles are continuously unloaded, even if the removal of the articles from the unloading section by the operator is not performed smoothly, the articles are separately transferred to and from the loading and transporting section. Since the plurality of retrieval units capable of transferring the plurality of articles are arranged in parallel, the loading / conveying unit can sequentially eject the plurality of articles to be retrieved from the plurality of retrieval sections, and There is no waste such as the loading / conveying unit waiting until the paper is unloaded, and the disadvantage that the operation efficiency of the equipment is reduced can be eliminated.

Therefore, as compared with a configuration in which a plurality of loading / conveying units are installed, the article can be unloaded without increasing the overall configuration of the equipment or significantly increasing the cost by a relatively simple structural improvement. It has become possible to provide an article storage facility capable of executing entry work as efficiently as possible.

[0010] According to the characteristic configuration of the second aspect, the article is a vehicle, and the entry and exit sections allow the vehicle to get on and off the road surface on which the article vehicle travels. Since it is installed as such, when loading or unloading a vehicle as an article, it is possible to run the vehicle and enter the storage section as it is from the road surface,
In addition, the vehicle can travel from the unloading section and be unloaded to the road surface as it is, so that loading and unloading operations can be performed efficiently. In addition, a configuration is also conceivable in which the entrance section and the exit section are formed, for example, by forming a pit on the road surface and housed in the pit. However, compared to such a configuration, the construction is simpler and the cost can be reduced.

According to a third aspect of the present invention, each of the placing / conveying section, the article storage section, the storage section, and the exit section is provided with an article transfer roller conveyor device. ing.

Since the roller conveyor device is configured to place and convey the articles by rotating the rollers for placing the articles, for example, the slat member is placed on the supporting member while the articles are placed like a slat conveyor. Noise is reduced as compared with a configuration in which the guide moves while being slid and guided. In particular, if the configuration is such that a heavy article is placed and conveyed, such as a vehicle, the effect of suppressing noise is large.
