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.
1. An automatic storage and retrieval system comprising: at least one entrance opening for entering goods into a three-dimensional warehouse; at least one delivery opening for delivering goods from the three-dimensional warehouse; a plurality of goods storage sections each having at least one layer of storage layer on which a plurality of unit goods storage sections are disposed in matrix; a goods conveyance structure provided in each of the unit goods storage sections, the goods conveyance structure being configured to receive/deliver stored goods by selecting the stored goods in a flexible direction; and a conveyance control device configured to direct 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.
2. The automatic storage and retrieval system as set forth in claim 1, wherein the goods conveyance structure comprises a conveyance direction change section for changing the conveyance direction to any one direction among forward, reverse, left and right directions, and a goods conveyance section for conveying the stored good in the direction changed by the conveyance direction change section.
3. The automatic storage and retrieval system as set forth in claim 1, wherein the goods conveyance structure comprises a conveyer line for conveying the stored good in one direction, and a cross-feeder disposed within the conveyer line, the cross-feeder delivering the stored good into another conveyer line for conveying in a direction perpendicular to the conveyance direction of the conveyer line from which the stored good is delivered.
4. The automatic storage and retrieval system as set forth in claim 1, wherein the goods conveyance structure comprises 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 inclination layer 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.
5. The automatic storage and retrieval system as set forth in claim 1, wherein the goods conveyance structure comprises 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.
6. The automatic storage and retrieval system as set forth in claim 1, wherein the conveyance control device is configured to control conveyance of the stored good to a neighboring unit goods storage section in a case that the neighboring unit goods storage section in the conveyance direction of the stored good has no stored goods.
7. The automatic storage and retrieval system as set forth in claim 4, wherein the conveyance control device is configured to control conveyance of the stored good to a neighboring unit goods storage section in a case that the neighboring unit goods storage section in the conveyance direction of the stored good has no stored goods.
8. The automatic storage and retrieval system as set forth in claim 5, wherein the conveyance control device is configured to control conveyance of the stored good to a neighboring unit goods storage section in a case that the neighboring unit goods storage section in the conveyance direction of the stored good has no stored goods.
9. The automatic storage and retrieval system as set forth in claim 1, wherein the conveyance control device is configured to search for a detour in a case that the neighboring unit goods storage section in the conveyance direction of the stored good has stored goods, and wherein the conveyance control device is configured to control conveyance of the stored good in the detour direction in a case that the detour exists.
10. The automatic storage and retrieval system as set forth in claim 4, wherein the conveyance control device is configured to search for a detour in a case that the neighboring unit goods storage section in the conveyance direction of the stored good has stored goods, and wherein the conveyance control device is configured to control conveyance of the stored good in the detour direction in a case that the detour exists.
11. The automatic storage and retrieval system as set forth in claim 5, wherein the conveyance control device is configured to search for a detour in a case that the neighboring unit goods storage section in the conveyance direction of the stored good has stored goods, and wherein the conveyance control device is configured to control conveyance of convey the stored good in the detour direction in a case that the detour exists.
12. The automatic storage and retrieval system as set forth in claim 1, wherein the conveyance control device is configured to search for a detour in a case that the neighboring unit goods storage section in the conveyance direction of the stored good has stored goods, and wherein the conveyance control device is configured to compare the delivery date and time of the stored good for conveyance and the delivery date and time of the stored good in the neighboring unit goods storage section, and wherein the conveyance control device is configured to make the stored good in the neighboring unit goods storage section to take shelter in a case that the delivery date and time of the stored good for conveyance is earlier.
