Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to the transfer, temporary storage, and loading of luggage in a rack site.
The present invention relates to a three-dimensional warehouse characterized by a loading / unloading mechanism.

(Prior Art) A conventional example of a three-dimensional warehouse will be described with reference to FIGS. 12 and 13. A rack structure (1) having a large number of rack portions arranged in parallel and in multiple stages is provided via a floor passage (2). Erect in parallel, the floor road
Place the side column (101a) on the traveling rail (3) provided in (2).
And a stacker crane (101) including an elevator (101b) that is vertically operated in the side column and a drive device (not shown) for the elevator, and a rack structure (1). Outside the existing rack site, there is a guideway (8) for the carriage (5).
The stacker crane (101) is equipped with
Run in the floor path (2) between each rack structure (1) (1)
By moving (101b) up and down, luggage (a) enters and leaves each rack part of each rack structure and is transported on the rack premises, and the luggage is transferred, temporarily placed, or inherited with the transport carriage (5). Is performed outside the rack site, and the stacker crane occupies the floor passage between the rack structures and the space above it.

(Problems to be solved by the invention) In the conventional three-dimensional warehouse, the floor path between the rack structures and the space above the stack structure are occupied for the traveling movement of the stacker crane, and the stacker crane and the ground transportation means (transportation trolley, etc.) Since the transfer of goods (transfer, temporary storage) between the racks is performed outside the rack site, a large transfer site is required outside the rack site, and the floor path between the rack structures is not effectively used. Due to the long transportation distance of luggage due to the fact that it is inefficient and becomes a bottleneck for improving efficiency, the stacker crane requires a high side column corresponding to the height of the rack structure, and the stack structure of the rack structure is high. However, there are problems such as large size, increased weight, and high cost.

The present invention was developed in order to address the above-mentioned problems, and the purpose thereof is to cope with the increase in the height of rack structures and to effectively utilize the floor passage between the rack structures. It is to provide a three-dimensional warehouse that has improved storage and delivery performance and efficiency as well as downsizing and simplification of the mechanism.

(Means for Solving the Problem) The present invention is arranged on a trolley rail (10) above a rack structure (1) that is oppositely placed via a floor passage (2), and the same floor passage (1) is provided. 2) a trolley (11) running above the trolley (1
(1) A lifting platform (13) suspended by a hoisting rope (12) so that it can be lifted and lowered, and the lifting platform (13) is attached to the lifting platform (13) so that it can move back and forth. Attaching / detaching fixing device for fixing to (1)
(20) and the transfer temporary placement device (3) for transferring the load to the lift table (13) via the turntable (31) so as to move vertically and horizontally.
(0) and characterized in that the trolley rail above the rack structure runs over the floor of the trolley, the trolley raises and lowers the lift, and the attachment / detachment device fixes the lift to the rack structure. , And the transfer / temporary placement device attached to the lift table, the temporary placement function allows the floor path between the rack structures to be transported by the ground transporter and used as a temporary placement path for quick entry and exit. Carry out smoothly.

(Operation) The trolley rail provided above the rack structure causes the trolley to travel above the floor between the rack structures, and the lifting platform is lifted and lowered by the hoisting rope of the trolley. It is fixed to the rack structure to prevent it from toppling over, and by the transfer / temporary placement device attached to the lifting platform, the transfer and temporary transfer of the cargo between each rack part of the rack structure and the floor road or the floor road is performed. Placement is carried out smoothly, and the floor is used for the transportation of the ground carrier by the elevation of the lifting platform and is used as a temporary placement route.Luggage is delivered within the floor and the loading, unloading, and transporting of luggage is efficient. Carried out.
