[0048] (1) Overall structure

[0049] use Figure 1 ~ Figure 2 The automatic warehouse system 1 according to the first embodiment will be described. figure 1 It is a schematic plan view showing the arrangement structure of the automatic warehouse system according to the first embodiment. figure 2 is a brief main view of the automated warehouse system.

[0050] The automatic warehouse system 1 has a plurality of automatic warehouses 3 and a plurality of transport vehicles 5 .

[0051] Each automatic warehouse 3 has a pair of shelves 7 (first shelf 7A and second shelf 7B) and one stacking crane 9 . The plurality of automated warehouses 3 are arranged such that the rear surfaces of the shelves 7 are adjacent to each other. The transport vehicle 5 carries the article A in and out with respect to the plurality of automatic warehouses 3 .

[0052] In the following, the longitudinal direction of the shelf 7 is the first horizontal direction, indicated by the arrow X. As shown i...

no. 2 approach

[0129] In the first embodiment, one stacking crane 9 is provided in each automatic warehouse 3 , but the number of stacking cranes 9 may be plural.

[0130] use Figure 9 , such a modified example will be described as the second embodiment. Figure 9 It is a schematic plan view showing the arrangement structure of the automatic warehouse system according to the second embodiment. In addition, in the description of this embodiment, the point which differs from 1st Embodiment is demonstrated.

[0131] Such as Figure 9 As shown, in the automatic warehouse system 1A according to the second embodiment, each automatic warehouse 3 has two stacking cranes 9 arranged in series. The route 21 on which the transport vehicle 5 travels includes two first routes 21A, two second routes 21B, and three connecting routes 21C. In the present embodiment, the first route 21A is provided near the other end near one end and the center of the lower portion of the first shelf 7A in the first horiz...

[0137] In the first embodiment, the movement restricting device 41 is arranged in the entire area between the crane tunnel 11 and the front surface of the shelf 7 facing the crane tunnel 11 . However, it is sufficient if the movement restricting device 41 is provided in the opening 7 b corresponding to the storage port 13 and the storage port 15 of the rack 7 , and thus is not limited to the first embodiment.

[0138] use Figure 10 , such a modified example will be described as a third embodiment. Figure 10 It is a schematic plan view which shows the arrangement|positioning structure of the automatic warehouse system which concerns on 3rd Embodiment. In addition, in the description of this embodiment, the point which differs from 1st Embodiment is demonstrated.

[0139] The automatic warehouse system 1B has a movement restriction device 41A. The movement restricting device 41A is provided on the side of the crane passage 11 corresponding only to the openings 7b of the sto...

Abstract

Provided is an automated warehouse system in which a transport vehicle travels on the lower portion of a rack, wherein stacker cranes, which are not stacker cranes performing maintenance, are allowedto operate. This automated warehouse system 1 comprises a plurality of automated warehouses 3, a transport vehicle 5, and a movement restriction member 43. The plurality of automated warehouses 3 has:racks 7 that are long and extend in a first horizontal direction and that have a plurality of shelves 7a; and a stacker crane 9 that can travel on a crane route 11 along the racks 7. The plurality ofautomated warehouses 3 is disposed so that back faces of the racks 7 in a second horizontal direction orthogonal to the first horizontal direction are mutually adjacent. The transport vehicle 5 is provided at the lower portion of the racks 7 and can travel along a route 21 that is long and extends in the first horizontal direction. The movement restriction member 43 is disposed between the craneroute 11 and the front face of the rack 7 facing the crane route 11 and can move between a movement restricted position, in which movement of an operator W is restricted, and a movement non-restrictedposition, in which the restriction is cancelled.

Description

technical field [0001] The present invention relates to automatic warehouse systems. Background technique [0002] Conventionally, an automatic warehouse system is known that includes a plurality of automatic warehouses that have racks and a stacking crane, and a transfer vehicle that travels along a predetermined route and transports articles into and out of the plurality of automatic warehouses. library (for example, refer to Patent Document 1). [0003] In the automatic warehouse system described in Patent Document 1, the inside of the rack is utilized as a waiting place for transport vehicles to make the system area compact. [0004] Patent Document 1: Japanese Patent Application Laid-Open No. 11-116004 [0005] In the prior art described above, in order for the stacking crane to transfer goods between the racks of the racks on both sides, the lowermost rack of the rack is opened toward the crane passage side. Therefore, when an operator enters the crane tunnel during...
