[0008] Delivery request board 8a, 8b, 8c...8h
is provided with a push button for issuing a delivery request, and is connected to the delivery control device 9 via a signal line.

[0009] Warehouse request board 4a, 4b, 4c...4t
is provided with switches for setting the product name code, quantity, etc. for requesting warehousing, and push buttons for requesting warehousing, and is connected to the warehousing control device 5 via a signal line.

Reference numeral 5 denotes a warehousing control device composed of a microcomputer, to which a CRT 5a and a keyboard 5b are connected.

Reference numeral 6 denotes a central control device connected to a CRT 6a and a keyboard 6b, and connected to each of the warehousing control device 5, the warehousing control device 9, and the ground control device 7 of the stacker crane via bidirectional communication cables.

Reference numeral 7 denotes a ground control device for the stacker crane 3, which is connected to the stacker crane 3 via a bidirectional communication cable.

[0013] Reference numeral 9 denotes a delivery control device composed of a microcomputer, to which a CRT 9a and a keyboard 9b are connected.

FIG. 3 shows an example of a shipping request waiting table created in the central control device 6. In this example, a value of 0 in the shipping order column indicates that no exit request has been made for the exits A to H, and a non-zero value indicates that the corresponding exits A to H
Indicates that a shipping request has occurred. At this time, the order of delivery corresponds to the order in which the delivery requests occur. The information in the exit request waiting table created in the central control device is output to the CRT along with the exit processing order, and any one of the displayed exit request waiting tables is output.
By specifying the first item to be delivered using an interactive method such as a keyboard, it is possible to immediately leave a delivery request that was entered later in the order. By creating a data table for waiting for issuing requests in the issuing control device, displaying this information together with the order of issuing processing on the CRT, and specifying any one of the displayed waiting requests for issuing requests using an interactive method such as a keyboard. , it is possible to urgently issue a delivery request that was entered late in the order of entry.

Next, the operation of the present invention will be explained with reference to the flowchart shown in FIG. When requesting warehousing, 1) The warehousing operator must use the warehousing request panels 4a, 4b, 4c.
When the warehousing request button of 4t is pressed, the warehousing request data is transmitted to the central control device 6. 2) If the stacker crane 3 is not in operation, the central control device 6 immediately creates a warehousing operation schedule for the stacker crane 3 and transmits the warehousing operation schedule to the ground control device 7 of the stacker crane 3.

[0016] When making a shipping request, 1)
The shipping operator inputs the product name code of the item to be shipped from the keyboard 9b of the shipping control device 9. 2) The delivery control device 9 transmits this product name code to the central control device 6. The central control device 6 searches for the presence or absence of inventory for this product name code, and sends the inventory information to the shipping control device 9.
Transmit to. The shipping control device 9 displays this inventory information on a CRT.
9a. 3) The unloading operator makes a reservation to which exit A, B, C, . . . H, the goods to be unloaded will be delivered, while checking the inventory information on the CRT 9a. 4) The exit operator operates each exit A, B, C...
- Delivery request panels 8a, b, c installed corresponding to H.
. . . When the exit request button of h is pressed, the exit control device 9 transmits the exit request data to the central control device 6. If the stacker crane 3 is in operation, the central control device 6 registers this delivery request in the delivery request waiting table of FIG.
If it is not in operation, an unloading operation schedule for the stacker crane 3 is immediately created and transmitted to the stacker crane ground control device 7. Stacker crane ground control device 7
converts this stacker crane operation schedule into travel and elevation information of the stacker crane 3 and transmits operation commands to the stacker crane 3. When the central control device receives the operation completion signal of the stacker crane 3, it executes the unloading request in the unloading order 1 in the unloading request waiting table as the next unloading request, and at the same time deletes this unloading request data and leaves the remaining unloading request data. Move up the shipping order of the data waiting for a shipping request.

The central control device 6 displays the exit status screen 10 and the exit reservation screen 11 shown in FIG. 4 on the CRT 6a based on the information in the exit request waiting table. If it becomes necessary to first execute the Waiting for Output Request whose outgoing order is registered later in the outgoing order, the operator can
1 and the exit reservation mark 11a, and confirm the correspondence between the exit reservation product name and its exit exit.

Then, using the keyboard 6b, the priority exit instruction cursor 10a displayed in the priority exit instruction field of the exit status screen display 10 is aligned with the name of the exit opening to be prioritized, and the priority exit is designated. . At this time, if the priority retrieval process is not registered, the central control device turns on the priority retrieval flag in the retrieval request waiting data of the designated exit exit, registers it, and registers the priority retrieval process on the retrieval status display screen 10. Display the completed mark 10b. Furthermore, if priority issue has already been registered, this will be ignored.

The central control device 6 usually performs the shipping process starting from the item in the shipping order of 1 in the shipping request waiting table shown in FIG. to be executed.

In this embodiment, the keyboard 6b of the central control unit is used to move the cursor and specify the priority exit reservation, but an input device such as a touch panel switch may also be used. Alternatively, the same unloading method can be achieved by creating a unloading request waiting table in the unloading device, performing the above management, and transmitting the unloading requests to the central control unit in order of priority when the stacker crane completes its operation. be.

[Effects of the Invention] If you want to immediately process a retrieval request that is later in the order in the retrieval request waiting table, the retrieval operator can specify priority retrieval without canceling all the retrieval request waiting tables. Since the process can be done in a short time, continuous delivery is possible.
