Next, the operation and effect when an abnormality occurs in the inventory management system configured as described above will be described. Incidentally, “S” shown in FIG. 5 corresponds to the step in the specification.

First, when an abnormality occurs, the worker pushes the abnormality button B. Then, an abnormal signal is output to the control computer 15. Then, the control computer 15 outputs an abnormality occurrence signal to the inventory management computer 16. At this time, the display 20 of the inventory management computer 16
Is displayed on the screen. Then, the operator visually recognizes the display on the display 20, and the keyboard 2
1 is operated to output an abnormality recovery signal from the keyboard 21 to the inventory management computer 16.

Then, as shown in the flow chart of FIG. 5, the inventory management computer 16 at step 101
The work instructed data list 23 is created, and the printer 22
Print on.

Next, at step 102, the inventory management computer 16 performs work-instructed data processing. That is, the inventory management computer 16 deletes the data of the in-stock and out-work work instructed data from the memory 16a. Further, the inventory management computer 16 stores the packing box W from the left conveyor 12b of the picking conveyor 12 into a predetermined storage unit in which the packing box W was initially stored, based on the picking operation instructed data or the re-entry unpaid data. The work instruction data (return work instruction data) for performing is created and stored in the memory 16a. After that, the inventory management computer 16 erases the picking operation instructed data and the re-entry unpaid data from the memory 16a.

In step 103, the inventory management computer 13 erases the uninstructed work data for warehousing from the memory 16a, and stores the uninstructed work data for warehousing and picking work in the memory 16a as it is unprocessed.
That is, the inventory management computer 16 executes the step 102,
At 103, work instruction data is automatically maintained.

Then, in step 104, the inventory management computer 16 creates a picking order list based on the work instructed data list and prints it from the printer 22.

On the other hand, the worker is the inventory management computer 1
While looking at the work instructed data list 23 created in 6, the work for recovering the abnormality (abnormality recovery work) is performed. For convenience of explanation, it is assumed that the packing boxes W having the product numbers “A” to “E” described in the lists 23 and 24 are stored in the packing box W on the track guided vehicle 13 as shown in FIG. To do.

In this abnormal recovery work, the worker temporarily removes the packing boxes W of the product numbers "A" to "E" on each tracked carriage 13 from the tracked carriage 13. Then, since the load of the product number “B” is a load for shipping, the packing box W in which the load is stored is placed on the shipping conveyor 11 and the shipping is completed. Since the load of the product number “D” is a load for warehousing, the load box W in which the load is stored is placed on the warehousing conveyor 8 and warehousing is performed again.

Furthermore, the worker follows the picking order list and selects the product numbers “A”, “C”,
The restoration work of the packing box W containing "E" is performed. That is, the worker inserts the packing box W storing the loads of product numbers “A”, “C”, and “E” into the left conveyor 12 on the left side of the load detection sensor 12c.
On track b, "A", "C", and "E" are placed in this order from the track 14 side. At this time, since the load with the product number “A” is for picking and receiving, the loads with the product numbers “C” and “E” are for loading and unloading after leaving the load with the product number “A” as it is. After picking a predetermined number from the packing box W, they are placed in the order of “A”, “C”, and “E”.

In this way, when the worker completes the load recovery work while looking at the lists 23 and 24, the worker resets the control computer 15 and the cargo handling equipment, and then
The keyboard 21 of the inventory management computer 16 is operated to output an operation restart signal for starting the automatic operation to the inventory management computer 16. Then, the inventory management computer 16 first outputs the return work instruction data to the control computer 15, and then outputs each work instruction data stored in the memory 16a to the control computer 15. That is,
Product numbers “A”, “C” on the picking conveyor 12
After the packing boxes W each containing a load of "E" are sequentially stored in a predetermined storage unit, various works indicated by the work instruction data stored in the memory 16a are performed and the operation is restarted.

Therefore, according to the present embodiment, the worker can easily determine which part number the load in each packing box W is by looking at the work instructed list 23, and each packing box W. It is possible to judge which work is a packing box W such as a loading, unloading or picking work. For this reason, the operator can easily determine which cargo handling equipment should be carried in order to recover the abnormality of the cargo box W. Therefore, the abnormality recovery work can be performed reliably and quickly. That is, it is possible to reduce the maintenance work time and labor.

The picking order list 24 allows the worker to easily place the packing boxes W for picking work on the picking conveyor 12 in a predetermined order.
Therefore, the abnormal recovery work can be reliably and promptly performed on the packing box W for the picking work.

Further, the inventory management computer 16 automatically maintains the work instructed data and the work non-instructed data only by operating the keyboard 21 and outputting an abnormality recovery signal to the inventory management computer 16, so that an abnormality occurs. Can shorten the time to restore the
It can be reliably restored.

Further, since the work instructed list 23 and the picking order list 24 are printed on the paper by the printer 22, the worker is informed of the printed work instructed list 2
Since it is possible to carry out the recovery work such as confirmation of the load by always holding 3 and the picking order list 24, the recovery work can be carried out more reliably.

The present invention is not limited to the above embodiments, but may be modified as appropriate without departing from the spirit of the invention. (1) In the above embodiment, the work instructed list 23 and the picking order list 24 are printed by the printer 22, but they may be displayed on the display 20.
