DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving stand for a three-dimensional automatic warehouse and an electric receiving truck for a three-dimensional automatic warehouse.

[0002]

2. Description of the Related Art A three-dimensional automatic warehouse is an apparatus for increasing the space storage rate by increasing the shelves for storing loads and increasing the space storage ratio. It is composed of an inventory management device and the like. The load placed on the forklift and moved is placed on a load receiving table provided in front of the automatic warehouse, and a shelf to be stored by the inventory management device is determined. When shelves to be stored are determined, the shelves are received from the receiving tray by the stacker crane, transported to the determined shelves, and stored. In order to issue goods, the information of the goods to be issued is input to the inventory management device and compared with the inventory management information.
The corresponding shelf is searched, and a stocking command is given to the stacker crane. When given a command, the load removed from the shelves by the stacker crane is placed on the loading tray,
It is handed over to a forklift from the receiving platform and moves.

FIG. 6 is a perspective view of a conventional receiving stand for a three-dimensional automatic warehouse, FIG. 7 is an enlarged perspective view of the receiving stand, and FIG. 8 is a partially enlarged view of a hanging portion of the receiving stand related to FIG. is there. In the figure, reference numeral 1 denotes a three-dimensional automatic warehouse. Reference numeral 2 denotes a rack panel of the automatic three-dimensional warehouse 1, which is configured in multiple rows and multiple stages. Reference numeral 3 denotes a shelf provided on the rack panel 2. Load 4 on each shelf 3,
It is stored on a pallet (not shown). Reference numeral 5 denotes a stacker crane that runs along the shelf 3 in the longitudinal direction of the shelf 3. 6 is a traveling device of the stacker crane 5, 7 is a loading platform,
Reference numeral 8 denotes a lifting device. 9 is a traveling rail of the stacker crane 5, and 10 is an upper guide rail. Reference numeral 11 denotes a cargo handling area provided at the entrance of the automatic warehouse 1. 12
Is a cargo receiving table provided at the cargo handling place 11.

[0004] As shown in FIG. 7, a loading table 12 has a lower frame 12A having four pillars 12a fixed to the ground.
And an upper frame 12B having four columns 12e on which a load receiving material 12g is laid, and a plurality of bolts 12i extending from the upper end of the lower frame 12A to the lower end of the upper frame 12B.
It is swingably suspended.

[0005] The lower frame 12A includes a beam 12b suspended between four columns 12a and a bracket 12c protruding outwardly in a direction perpendicular to the traveling rail 9 of the stacker crane 5 at the upper end of each column 12a. And a base 12d provided at a lower end of the column 12a.

[0006] The upper frame 12B includes a bracket 12c.
Four pillars 12e and 12 provided at the tip side of the
e, a beam 12f extending between the columns 12e in a direction along the traveling rail 9 and a load receiving material 12g provided at the upper end of the column 12e in a direction orthogonal to the beam 12f and a bracket 12c at the lower end of the column 12e.
12h and the load receiving material 12 provided below and facing each other.
g has guides 12j provided at both ends.

[0007] The upper frame 12B is
It is swingably suspended by four bolts 12i from the bracket 12c of A through the bracket 12h of the upper frame 12B, and is generally called a self-aligning type loading table. The beam 12f is provided below the load receiving material 12g so as not to obstruct a fork of a crane or a forklift (not shown) when transferring a load. As shown in FIG. 8, the upper frame 12B of the self-centering type loading table is suspended swingably so that when a load is temporarily placed on the load receiving material 12g, the center of the load is the upper frame 12B.
If the center is shifted from the center of the upper frame 12B, the center of the load coincides with the center of the upper frame 12B. When the fork of the crane or the fork of the forklift completes the transfer of the load, and the fork leaves the load, the upper frame 12B returns to the original position.

When the cargo 4 is stored in the automatic three-dimensional warehouse 1,
The incoming cargo 4 is placed on a forklift (not shown) and moved, and is temporarily placed on a cargo receiving table 12 provided in a cargo handling area 11 in front of the automatic three-dimensional warehouse 1. Arrow A indicates the forklift entry direction of the forklift. Stacker crane 5

A cargo receiving stand, wherein the receiving stand for a three-dimensional automatic warehouse having two or more receiving members at the top and bottom is provided.

[0012] The above-mentioned loading tray has a lower frame having four pillars fixed on the ground, an upper frame having four pillars having two or more loading members arranged vertically, and an upper frame having four pillars. It is preferable that the lower end of the upper frame is a self-aligning type loading table that is swingably suspended by a plurality of bolts.

[0013] Further, the above-mentioned loading table may have four pillars fixed on the ground, and two or more stages of loading material vertically above and below the pillars.

According to the fourth aspect of the present invention, at the loading / unloading port at the entrance / exit opening of the three-dimensional automatic warehouse comprising multi-row / multi-stage shelves, stacker cranes, facilities for entrance / exit, etc.
The stacker crane is provided movably along the rails of the stacker crane. A three-dimensional automatic warehouse unloading electric bogie that temporarily places and mediates when delivering
An electric receiving truck for a three-dimensional automatic warehouse is provided, wherein the electric receiving truck of the electric receiving truck has two or more upper and lower receiving members on the cart.

[0015] The above-mentioned loading table has a lower frame having four columns fixed on a carriage, an upper frame having four columns vertically extending two or more stages of loading material, and upper ends of these lower frames. It is preferable that the lower end of the upper frame be a self-aligning type loading table that is swingably suspended by a plurality of bolts.

[0016] Further, the above-mentioned loading table is fixed on a truck.
It may be one having a plurality of pillars and two or more stages of load receiving materials vertically above and below the pillars.

Next, the operation of the present invention will be described. When loading the cargo into the three-dimensional automatic warehouse, the incoming cargo is moved on a forklift (not shown) and moved to one of the two upper and lower stages of the loading table provided at the loading / unloading area at the entrance of the three-dimensional automatic warehouse. Or temporarily place it on the empty receiving material.
The stacker crane receives the load from the load receiving material on which one of the upper and lower tiers is placed, moves to the shelf, and stores it. On the other hand, when unloading the load, the stacker crane moves to the shelf storing the load to be unloaded, receives the load from the shelf, moves, and unloads the load in one of the two upper and lower stages of the receiving table. Place it temporarily on one of the receiving materials. The temporarily placed cargo is transferred from the cargo receiving material to a forklift and moves on the yard.

As described above, since the receiving material of the receiving table has two or more upper and lower stages, when a load brought by a forklift or a stacker crane is to be placed on the receiving table, all the receiving materials are blocked. There is almost no need to wait, and even if there is a time lag between the loading and unloading work with a forklift and the loading and unloading work with a stacker crane, it is possible to eliminate waiting time and improve the efficiency of overall loading and unloading work. it can.
