Abstract

PROBLEM TO BE SOLVED: To provide a load receiving table for an automatic warehouse system that can reduce the waiting time of warehousing-delivery and an AGV(Automated Guided Vehicle) to improve work efficiency. SOLUTION: This load receiving table 5 is installed at a warehousing-delivery port of the automated warehouse for putting loads in and out of a storage rack 1 by a travelable stacker crane 2, in order to carry out the delivery of the loads to and from the stacker crane and the delivery of the loads to and from the AGV 3. The load receiving table 5 has a plurality of receiving parts A-D around a rotating shaft part 6, and is rotatable so that when any one of the receiving parts is positioned to face the stacker crane 2, one of the other receiving parts is positioned to face the AGV 3 at the same time. The delivery of the loads to the AGV can be continuously performed with one load receiving table, so that the waiting time of warehousing-delivery and the AGV is dissolved to improve work efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a loading tray installed at an entrance of a stacker crane type automatic warehouse.

[0002]

2. Description of the Related Art In general, an automatic warehouse of the stacker crane type has a storage rack having a number of shelves on both sides of a movable stacker crane. A transfer device for loading and unloading is provided, and the transfer device is provided with means such as an arm for supporting a stored object.

An AGV (Automated Guided Vehi)
cle), the luggage conveyed in the storage rack can be stored in the storage rack by first loading the luggage from the AGV on the loading rack installed at the entrance / exit, and transferring the luggage from the loading rack to the stacker crane. It is designed to be stored on a shelf. Conversely, in order to transfer the baggage in the storage rack to the AGV, the baggage taken out of the rack of the storage rack by the stacker crane is temporarily placed on the receiving tray, and the AGV is moved from the receiving tray to the AGV.
The luggage is to be moved to. As a cargo receiving table installed at the loading / unloading port, a table capable of loading one load or a conveyor type table capable of loading a plurality of loads is used.

[0004]

The above-mentioned receiving tray cannot give the next instruction until the loading or unloading of the load on the receiving tray is completed. In other words, it is not possible to issue a mixed entry / exit instruction. For this reason, there is a problem that waiting time for the AGV and waiting for the storage rack to enter and leave the storage rack occurs, resulting in poor work efficiency.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems.
It is an object of the present invention to provide an automatic warehouse receiving tray capable of reducing the waiting time of V and improving work efficiency.

[0006]

In order to achieve the above-mentioned object, an automatic warehouse receiving tray according to the present invention is provided at an entrance / exit opening of an automatic warehouse for loading and unloading goods from a storage rack by a movable stacker crane. A load receiving pedestal installed and provided for transferring a load to and from a stacker crane and transferring a load to and from an AGV, comprising a plurality of receiving portions around a rotating shaft portion. It is characterized in that, at the same time as one receiving part is located at a position facing the stacker crane, the other receiving part is rotatable at a position facing the AGV.

[0007]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a schematic structural view showing an example of an automatic warehouse provided with a receiving table according to the present invention.

In FIG. 1, reference numeral 1 denotes a storage rack, which is installed in a state of being arranged in two rows, between which a stacker crane 2 runs. Each storage rack 1
The stacker crane 2 has a known structure having a number of shelves in the traveling direction and the vertical direction of the stacker crane 2.

Although the number of storage racks is two in FIG. 1, a larger number of storage racks may be arranged. in this case,
A plurality of storage racks are set in parallel with each other except for both ends, with the shelves back to back.

In FIG. 1, reference numeral 3 denotes an A for carrying a load.
The GV is adapted to move along a guide line 4 installed on the floor. Then, the AGV 3 does not directly transfer the luggage to and from the stacker crane 2, but transfers the luggage via the load receiving table 5 installed at the entrance of the automatic warehouse. That is, the AGV 3 transfers the load to and from the load receiving tray 5, and the stacker crane 2 also transfers the load to and from the load receiving tray 5.

[0012] Receiving table 5 installed at the entrance of the automatic warehouse
Has a structure having four receiving portions A to D around the rotating shaft portion 6, and any one of the receiving portions is a stacker crane 2.
And at the same time, it can be rotated so that any one of the other receiving portions is located at a position facing the AGV 3.

An example of loading and unloading of luggage performed in an automatic warehouse provided with the receiving table 5 having such a structure will be described. For example, the stacker crane 2, each receiving portion of the loading platform 5, the AGV
When the following instruction is given to each of the three, the operation becomes as shown in FIGS.

(Instruction) Stacker crane: 2 units are released (to receiving sections A and B) → 1
Receiving unit (from receiving unit D) Receiving unit A: Dispatch, Receiving unit B: Dispatch, Receiving unit C: No instruction, Receiving unit D: Receiving AGV: Receiving one unit (to receiving unit D) → Dispatch one ( (From receiving part A)

(Operation) First, as shown in FIG. 2, one piece of luggage is successively discharged from the stacker crane 2 to the receiving portions A and B. At this time, the receiving table 5 rotates 90 degrees. The AGV 3 is in a state of transporting incoming luggage. Next, the cargo receiving table 5 is rotated 90 degrees to the state shown in FIG. 3, and then the cargo is received from the AGV 3 into the receiving section D.
Subsequently, the receiving platform 5 is rotated 90 degrees to the state shown in FIG.
The AGV 3 receives the package from the receiving section A without waiting time.

As shown in this example, the presence of the rotary receiving tray 5 enables the stacker crane 2 to leave two AGVs without waiting for the AGV 3, and also allows the AGV 3 to leave the warehouse immediately after entering without waiting time. You will be able to receive your luggage.

As described above, the present invention has been described in detail based on the embodiment.
It is needless to say that the present invention is not limited to the above embodiment, and various changes can be made without departing from the spirit of the present invention.

[0018]

As described above, the automatic warehouse receiving tray of the present invention is installed at the entrance and exit of the automatic warehouse for loading and unloading cargo from the storage rack by the movable stacker crane, and is connected to the stacker crane. And a plurality of receiving parts around the rotation shaft part, for carrying out the delivery of the goods in and the delivery of the goods to and from the AGV,
One of the receiving parts is rotatable so as to be located at a position facing the stacker crane, and at the same time, the other receiving part is rotatable so as to be located at a position facing the AGV. Makes it possible to continuously deliver goods to the AGV.
Since the waiting time of V is eliminated, the work efficiency can be improved.
