[0002]

2. Description of the Related Art Conventionally, an automatic warehouse is provided with an inventory management device for managing loads stored in each storage unit.

This inventory management device is provided with an inventory management computer for each storage unit, which stores inventory data of loads stored in the storage unit. The inventory data consists of data such as the product number and quantity of the cargo. When the delivery request data is output from the keyboard to the inventory management computer, the inventory management computer searches, based on the delivery request data and the inventory data, whether or not there is a storage unit that stores the load indicated by the request data. If there is a storage unit that stores the requested load, the inventory management computer creates the leaving work instruction data and outputs the leaving work instruction data to the ground control panel (ground controller) which is a lower control device. The ground control panel controls the stacker crane via the crane controller on the basis of the work instruction data, and loads the load from the intended storage section.

If there is no storage unit for storing the requested load or if the stock is insufficient as a result of the search,
The inventory management computer displays the delivery request data as inventory shortage data on the display and outputs it from the printer.

[0005]

However, in order to issue a load based on the delivery request data that was not executed due to a lack of inventory, the worker must operate the keyboard again to re-enter the delivery request data. Therefore, there is a problem that it takes time and labor. Further, there is a problem that the worker needs to retain the stock shortage data displayed on the display or printed out until re-input.

This also applies to the warehousing work, for example, since the load is stored in all the storage sections of the automatic warehouse, even if the load cannot be stored, the storage request data is re-operated by operating the keyboard again. Need to enter.

The present invention has been made to solve the above problems, and an object thereof is to provide an automatic warehouse which can be easily re-stocked or unloaded.

[0008]

In order to solve the above problems, the invention according to claim 1 is a first storage means for storing inventory data indicating a storage state of a load in each storage section of an automatic warehouse;
An input means for outputting goods receipt or goods issue request data for requesting goods receipt or goods receipt to an automated warehouse, and goods receipt or goods receipt based on the above demand data based on goods receipt or goods receipt request data and inventory data If there is a storage unit that searches for whether there is a storage unit and a storage unit that can store or leave the storage unit, then from the storage units that can store or store the storage unit that stores or stores the storage unit. In the inventory management device of the automatic warehouse, which comprises the inventory management means for selecting and storing the work instruction data for performing the warehousing or unloading work with the storage part, the storage part which the searching means should enter or exit. If it is determined that there is no such, the second storage means for storing the entry or exit request data and the entry or exit request data stored in the second storage means are input to the search means. That a re-input command means for outputting a signal for the gist thereof.

The invention according to claim 2 is, in the invention according to claim 1, characterized in that the re-input command means is provided so as to be manually operable, and desired request data can be selected by manual operation.

According to a third aspect of the invention, in the second aspect of the invention, a display means is connected to the search means, and the display means can display the entry or exit request data stored in the second storage means. The gist is that the desired request data can be selected by being provided, and by manually operating the re-input command means based on the warehousing or warehousing request data displayed on the display means.

Therefore, according to the first aspect of the present invention, for example, in the case where the automatic warehouse is to carry out the leaving work, the worker operates the input means to output the leaving request signal from the input means. The searching means determines whether or not there is a storage unit storing the load indicated by the delivery request data, based on the delivery request data output from the input means and the inventory data stored in the first storage means. When the search means determines that the requested load is present, the inventory management means creates delivery work instruction data based on the delivery request data. On the other hand, when the search means determines that there is no requested load, the inventory management means stores the delivery request data in the second storage means. The leaving request data stored in the second storage means is input again to the searching means based on the signal from the re-input command means. Then, the search means again based on the delivery request data from the second storage means,
Do a search.

Even when the automatic warehouse is made to carry out the warehousing work, by outputting the warehousing request data from the input means, the same operation as the warehousing work can be obtained. In this case, the search means searches the storage request data and the inventory data to determine whether or not there is a storage unit that can store the requested load, and the storage request that cannot store the storage unit that can be stored in the second storage unit. The data is stored.

According to the second aspect of the invention, the entry or exit request data stored in the second storage means can be selected based on a manual operation of the re-input command means by an operator. According to the invention of claim 3, a display means is connected to the search means. Then, the display unit displays the storage or departure request data stored in the second storage unit, and the desired request data can be selected by operating the re-input command unit based on the display of the display unit.

Then, when there is a storage unit 3 that stores the parts to be delivered, the inventory management computer 31 creates delivery operation instruction data based on the delivery request data and inventory data, and stores it in the memory 31a.

If there is no storage unit 3 for storing the parts to be delivered, the inventory management computer 31 stores the delivery request data in the memory 31a as it is. At the time of the search, the inventory management computer 31 determines whether the parts having the product numbers to be delivered are not stored in any of the storage units 3, or if there is the storage unit 3 that stores the components having the product number to be delivered. When the quantity is less than the requested quantity, it is determined that there is “stock shortage”, and it is determined that there is no storage unit 3 that stores the parts to be delivered. Even if there is a storage part 3 that stores parts satisfying the product number and quantity, when another work is specified in the storage part 3, that is, it is specified by the leaving work instruction data stored in the memory 31a. When you are
It is determined that there is no storage unit 3 that stores the parts to be delivered. The data indicating "stock shortage" and "work in progress" is stored in the memory 31a of the delivery request data by the inventory management computer 31 as a reason for determining that the storage unit 3 storing the parts to be delivered does not exist. It is sometimes stored as reason data together with the delivery request data.

In the re-input mode, the inventory management computer 31 reads the delivery request data and the reason data indicating the reason stored in the memory 31a into the inventory management computer 31 again. Then, the delivery request data and the reason data thereof are displayed on the display 33.

FIG. 3 is an example showing the display state of the display 33. That is, the display 33 displays the "part number" and "quantity" of the parts, which are the contents of all the delivery request data stored in the memory 31a, and the "reason" that the delivery was not possible. In this case, on the display 33, the delivery request data output earlier is displayed in order from above.

In this display state, the operator can operate the cursor movement keys 32a for up and down movements while viewing the display on the display 33 to select the desired delivery request data.

First, the operator operates the keyboard 32 to output a warehousing / leaving switching signal to the inventory management computer 31 to set the work mode of the inventory management computer 31 to the warehousing mode. Next, in step 101,
The stock management computer 31 selects an input mode based on a shipping operation selection signal from the keyboard 32. That is, the inventory management computer 31 selects either the normal input mode or the re-input mode.

When the normal input mode is selected in step 101, the operator operates the keyboard 32 in step 102 to input the delivery request data from the keyboard 32 to the inventory management computer 31. That is, the operator operates the keyboard 32 to sequentially input the delivery request data indicating the parts to be newly delivered to the inventory management computer 31. Then, when all the desired delivery request data for which the delivery request should be issued are input to the inventory management computer 31, the worker presses the return key 32c. At this time, a return signal is output to the inventory management computer 31, and the inventory management computer 31 determines based on this return signal that the input of the delivery request data has been completed.

Further, when this return signal is output,
In step 103, the inventory management computer 31 searches the newly input all shipping request data in accordance with the input order to determine whether or not there is the storage unit 3 that stores the parts requested by each shipping request data. I do.

Of the plurality of delivery request data, if there is the storage section 3 in which the parts to be delivered are stored, the process proceeds to step 104, and the inventory management computer 31 outputs the parts to the storage section 3. The instruction data is created and stored in the memory 31a, and at the same time, the leaving work instruction data is output to the ground controller 24.

Then, the inventory management computer 31 stores the remaining delivery request data for which the delivery operation instruction data has not been created, in step 105, the storage section 3 in which the parts to be delivered by the search operation in step 103 are stored.
Determines whether there is any issue request data that was not retrieved. If there is no delivery request data for which the storage unit 3 to be delivered has not been searched, the process proceeds to step 101 and the delivery operation is selected again. If there is delivery request data for which the storage unit 3 storing the parts to be delivered has not been searched, the process proceeds to step 106, and in step 106 the delivery request data is stored in the memory 31a, and then step 10
Move to 1.

On the other hand, when the re-stocking mode is selected in step 101, the inventory management computer 31 manages the inventory request data stored in the memory 31a in step 107 together with the reason data indicating the reason. It is read into the computer 31. Then, as shown in FIG. 3, the inventory management computer 31 displays the read-out delivery request data and the reason thereof on the display 33. That is, the display 33 displays the delivery request data stored in the memory 31a. At this time, the operator operates the cursor key 32a of the keyboard 32 to select the leaving request data for the purpose of performing the leaving operation again. Then, the operator presses the return key 32b after selecting all the desired delivery request data. Then, the return signal is output to the inventory management computer 31, and the selection of the delivery request data is completed.

Further, when this return signal is output,
In step 103, the stock management computer 31 searches the re-entered all delivery request data in accordance with the input order to determine whether or not there is the storage section 3 in which the parts required by each delivery request data are stored. To do.

Then, the inventory management computer 31 performs the same processing as in the normal input mode in steps 104 to 106.
In addition, when the shipping operation instruction data is created in step 104, the shipping request data which is the source thereof is deleted from the memory 31a.

Therefore, according to the present embodiment, the shipping request data once input to the inventory management computer 31 from the keyboard 32 is stored in the storage unit 3 of the automated warehouse 1 in which the requested target parts are stored. Even without the part 3
It is stored in the memory 31a. Therefore, for example, after the target component is stored in the automated warehouse 1, the memory 3 is stored again.
When the desired parts requested by the shipping request data stored in 1a are to be shipped, the inventory management computer 31 creates shipping work instruction data based on the shipping request data stored in the memory 31a, and facilitates automatic warehouse. It is possible to let 1 perform the leaving operation. In this case, since the worker does not need to input the shipping request data from the keyboard 32,
You can save time and effort when typing. Moreover, the operator can easily select the leaving request data by manually operating the cursor key 32a while visually checking the leaving request data displayed on the display 33. In this case, desired delivery request data can be selected.

When the retrieval request data is not stored in the storage unit 3 for storing the parts requested by the retrieval request data and the retrieval request data is stored in the memory 31a, "insufficient stock", "work in progress", etc. The reason why the item was not delivered is also stored. Therefore, the reason why the shipping operation is not performed can be displayed on the display 33 together with the shipping request data, and the worker can easily know the reason why the shipping operation is not performed. Therefore, based on the reason, the worker can easily and surely perform the leaving operation by re-inputting the leaving request data from the memory 31a to the inventory management computer 31 after a predetermined time.
For example, if the delivery work is not performed due to "insufficient inventory", the delivery request data is re-input after the receipt work is performed to some extent, and the delivery work is performed for the reason "work in progress". If the “work in progress” has not been performed, the shipping work can be performed easily and reliably by re-entering the shipping request data after the work “in progress” is completed.
