automatic storage and retrieval system
automatic storage and retrieval systemAn automatic storage and retrieval system comprises at least one entrance opening, at least one delivery opening, a goods storage section having at least one storage layer in which unit goods storage sections are disposed in row and column, a goods conveyance section for selecting a stored good (rack) freely in direction and for accepting and sending out the stored good, the goods conveyance section being provided at each of the unit goods storage sections, and a conveyance control section for guiding the stored good to the delivery opening by the delivering date and time of the stored good upon reception of the stored good through the entrance opening.
It is an object of the present invention to provide an automatic storage and retrieval system and a method for conveying stored goods within a three-dimensional warehouse, both can utilize the storage space within the warehouse at the maximum, can carry out the conveyance from the entrance of the goods to the keeping of the goods, the delivery of the goods in an unmanned condition, and can securely deliver the goods at the expected date and time especially.
To realize the above object, an automatic storage and retrieval system of a first aspect according to the present invention is characterized in comprising: at least one entrance opening for entering goods into the three-dimensional warehouse, at least one delivery opening for delivering goods from the three-dimensional warehouse, goods storage section having at least one layer of storage layer on which unit goods storage sections are disposed in matrix; goods conveyance means provided in each of the unit goods storage sections, the goods conveyance means being able to receive/deliver stored goods by selecting the stored goods in a flexible direction, and conveyance control means for guiding the stored good to the delivery opening by delivery date and time of the stored good, upon entrance of the stored good through the entrance opening.
In an automatic storage and retrieval system of fourth aspect according to the present invention, the goods conveyance means have an inclined conveyer for conveying the stored good from the upper storage layer to the lower storage layer in a case that the goods storage section has multiple storage layers, and wherein the inclined conveyer has an entrance/delivery section for entering into/delivering from with respect to each storage layer which is one storage layer from the uppermost storage layer to the lowermost storage layer. In an automatic storage and retrieval system of fifth aspect according to the present invention, the goods conveyance means have an elevator for conveying the stored good from an upper storage layer to a lower storage layer, and vice versa in a case that the goods storage section has multiple storage layers.
In this automatic storage and retrieval system, the goods conveyance means is not limited as well as the means being able to receive/deliver the goods by selecting the stored goods in a flexible direction. For example, one of second to fifth aspect (described later) according to the present invention is preferably employed.
