The display of the load for which the work has been completed is displayed on the display device 19, after being discharged by the forklift 3.
It is erased from 24 respectively. Therefore, according to the present embodiment, since the worker can output the leaving request signal to the ground control panel 18 while riding on the forklift 3, it is possible for the worker to save the labor of getting off the forklift 3 and operating the ground control panel 18. Work efficiency can be improved. When the load to be unloaded is placed on the loading / unloading port 5a, a shipping completion signal is output to the terminal controller 28 and the display device 24
Is displayed on the display, it is possible to immediately know that the shipping is completed by visually recognizing the display.
Since there is no need to wait for the load to be delivered at, work efficiency can be improved. At this time, the alarm buzzer 25 sounds to surely notify the operator of the completion of leaving the warehouse.

In addition, when there are a plurality of delivery requests, the ground controller 29 determines, based on which delivery request signal, the delivery completion signal is based on which delivery request signal when the delivery is completed. Output to. Therefore, the worker on each of the forklifts 3a to 3b can easily determine whether or not the load whose shipping is completed is the load requested by the worker based on the display on the display device 24. Therefore, the worker can reliably take out the load requested by him / her, and can prevent the other forklift 3 from carrying out the load requested by mistake.

Further, since the delivery completion signal is output when both the load detection sensors 7a and 7b provided at the loading / unloading port 5a detect the load, it is possible to easily determine the delivery completion.

When the delivery operation based on the delivery request signal output earlier is completed, the delivery operation of the load based on the next delivery request signal is immediately started, so that the work efficiency can be improved.

In addition, when the worker takes out the load, the data of the product number and the number of the load to be put out is sent to the information terminal device 2.
Since the desired load can be easily delivered by simply inputting from 3, it is possible to efficiently perform the delivery operation.

In addition, the forklift 3 side and the automatic warehouse 1
Since the radios 22 and 27 are communicated with the ground control panel 18 for controlling the radio communication, the mechanism for the communication can be simplified as compared with the case where the communication is performed by wire or the like.

The present invention is not limited to the above-described embodiments, but can be implemented as follows with a part of the structure appropriately changed without departing from the spirit of the invention. (1) In the above-described embodiment, as the delivery status signal, the delivery completion signal indicating the completion of delivery and the delivery in-process signal are output. This is the ground controller 2 during the delivery work.
9 may calculate the time until completion of the shipping based on the address where the load to be shipped is stored, and display the time until the completion on the display devices 19 and 24. In this case, from the ground controller 29 to each terminal controller 2
A time signal indicating the time until the delivery is completed is sequentially output to 8, and each display device 24 displays the time until the delivery is completed based on this time signal.

Further, the notification buzzer 25 may be sounded when the time until the delivery is completed reaches a predetermined time. Therefore, the worker can easily understand the time until the delivery is completed by the display device 24 and the notification buzzer 25, and can perform other cargo handling work before the delivery is completed.

The work status of the stacker crane 2 may be displayed on the work status display sections 19d and 24d. For example, the storage unit 5 in which the stacker crane 2 stores the load to be unloaded.
“While traveling” indicating that the vehicle is traveling toward, “Under unloading work” indicating that the unloading work is being carried out in the storage section 5, the unloading operation in the storage section 5 is completed, and A display such as "traveling on the way back" indicating that the vehicle is traveling toward the exit port 5a may be displayed.

(2) In the above embodiment, a plurality of loading / unloading ports may be provided. In this case, the worker outputs, from the information terminal 23 to the terminal controller 28, in addition to the product number and the number of the cargo to be unloaded, the loading / unloading port to be unloaded.

(3) In the above embodiment, the worker inputs the article number and the number of the load to be delivered to the information terminal 23 as the data of the load to be delivered. You may enter the address.

(4) In the above embodiment, the forklift 3 is used as the moving body, but a tracked truck that travels on a predetermined track may be used. (5) In the above embodiment, when the load detection sensors 7a and 7b both detect a load on the loading / unloading port 5a, it is determined that the shipping operation has been completed, and the next shipping operation is started. The ground controller 29 places the load on the loading / unloading port 5a, completes the loading / unloading work, and further, the forklift 3 performs the loading work, and the load detection sensors 7a and 7b both load the load. When the detection is stopped, the leaving operation may be performed based on the next delivery request signal output.

(6) In the above embodiment, the ground controller 29 may judge the completion of the leaving work based on the output signal from the work completion button 6. (7) In the above-described embodiment, the invention is applied to the manned forklift 3 on which the worker is riding, but it may be applied to an unmanned vehicle such as an unmanned forklift.

In this case, the controller mounted on the unmanned vehicle determines the unloading status of the load based on the output signal from the ground controller 29. Then, when the unattended vehicle is directed to the entry / exit port 5a when the exit completion signal is output to the controller of the unmanned vehicle, the unmanned vehicle is unloaded to the entry / exit port 5a.
There is no need to wait for the load to be delivered in front of.

(8) In the above embodiment, when the delivery of the load is completed, only the notification buzzer 25 of the information terminal machine 23 mounted on the machine base requesting the load is sounded. For example, the terminal controller 28 may sound the notification buzzer 25 of the machine that does not request the load based on the exit completion signal. In this case, the sound of the alert buzzer 25 of the machine requesting the load and the alert buzzer 2 of the machine not requesting the load
The sounds of 5 may be different from each other. Further, the time at which the notification buzzer 25 sounds may be changed between the machine that requests the load and the machine that does not request the load. For example, the alert buzzer 25 may sound longer for a machine that has requested a load than for a machine that has not requested a load.
