Abstract

PURPOSE:To reduce the work of ID attachment at a stock control using a manned cargo handling vehicle, by arranging so that ID reading and a vehicle position detection may be conducted by the operation of a switch at the time of cargo placing, and writing in as a stock information may be done, and an opposing information may be erased by the operation of the switch at the time of cargo taking out. CONSTITUTION:A switch means 3 is operated when an operator has placed cargo at a cargo handling place. As a result, a concentration controller 8 outputs a data reading command to a reader 1 and a vehicle position detector 2. Then, the reader 1 reads the ID of the cargo, and the vehicle position detector 2 reads a vehicle position, and delivery is made to the concentration controller 8. The concentration controller 8 writes this into a data memory 4 as a stock information. Also, the concentration controller 8 erases an opposing information within the data memory 4 by the operation of the switch means 3 at the time of cargo taking out. Thus, the work of ID attachment can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an inventory management method for a cargo handling area using a manned cargo handling vehicle.

However, it could not be applied to location a, which is a vertically stacked type where cargo C is directly stacked as shown in Fig. 4, because it is not possible to directly attach an ID.

The present invention has been made in view of the above circumstances, and its purpose is to enable inventory management even in rack-type, flat-type, and vertically stacked locations, and to be able to manage inventory even in rack-type locations. In such a case, it is an object of the present invention to provide an inventory management method for a cargo handling vehicle that eliminates the need to affix IDs to all locations on the rack and can reduce the effort required to affix IDs.

[Means and operations for solving the problems] In order to achieve the above object, the present invention provides a reading device for reading the ID of cargo, a vehicle position detection device for detecting the position of the cargo handling vehicle, a switch means, a data memory, and a centralized The central control device issues data reading commands to the reading device and the vehicle position detection device by actuation of the switch means during cargo loading, reads data from these devices, and stores this information in the data memory 4. By operating the switch means at the time of unloading the cargo, the data is read in the same way as in the case of storing the cargo and the central control device erases the corresponding information from the data memory.

〔Example〕

The present invention will be explained below based on FIG.

Fig. 1 shows a control device mounted on a cargo handling vehicle. It is equipped with a switch means 3 including a judgment switch capable of determining when a load is carried and when it is not carried, a data memory 4 for inventory information, and a central control device 8.

The vehicle position detection device 2 also includes a road surface ID reading device 5 that reads a location ID pasted on the road surface, and a work equipment height detection device 6 that detects the height of the work equipment during cargo handling work.
Further, the judgment switch and the like include non-contact switches such as light and ultrasonic switches.

Next, the operation will be explained.

When the operator places the cargo at the cargo handling area, he presses the switch of the switch means 3. Also, the decision switch is activated. For this purpose, the central control device 8 issues data reading commands to the reading device 1 and the vehicle position detecting device 2, and reads data from these devices 1.2. Then, this information is written into the inventory information data memory 4, and the position information of the load can be determined from the road surface position and the height of the load, and becomes inventory information.

Further, when picking up the cargo, the operator presses the switch of the switching means 3 for picking up the cargo.

Or, when the judgment switch is activated, the data is read in the same manner as in the case of the cargo storage described above. Then, the central control device 8
deletes the corresponding information from the data memory 4.

This makes it possible to erase the information about the item that has been picked up from the management information.

Inventory management in the cargo handling area is performed using the method described above.

〔Effect of the invention〕

As described above in detail, the cargo handling vehicle inventory management method according to the present invention includes a reading device for reading the ID of cargo, a vehicle position detection device for detecting the position of the cargo handling vehicle, a switch means, a data memory, and a central control device. In preparation, the central control device issues data reading commands to the reading device and the vehicle position detection device by actuation of the switch means when loading cargo, reads data from these devices, writes this information to the data memo IJ 4, and stores the inventory. The data is read in the same manner as in the case of the above-mentioned cargo storage by operating the switch means when unloading the cargo, and the central control device erases the corresponding information from the data memory. Inventory management can also be performed at floor-standing and vertically stacked locations.

In addition, in cases such as rack-type locations, I
Since the ID is pasted on the rack, there is no need to paste the ID on all locations on the rack, and the effort required for pasting the ID can be reduced.

[Brief explanation of the drawing]

FIG. 1 is an explanatory diagram of the configuration of a control device used in the method of the present invention, and FIGS. 2, 3, and 4 are explanatory diagrams of the shapes of locations for cargo handling operations. 1 is a reading device, 2 is a vehicle position detection device, 3 is a switch means, 4 is a data memory, and 8 is a central control device.

Claims (1)

[Claims] It is equipped with a reading device that reads the ID of cargo, a vehicle position detection device that detects the position of the cargo handling vehicle, a switch means, a data memory, and a central control device. A command to read data is issued to the position detection device, the data from these devices is read, this information is written to the data memory 4 as inventory information, and the above-mentioned case of cargo storage is performed by operating the switch means when picking up the cargo. A cargo handling vehicle inventory management method characterized in that the data is read in the same manner and the corresponding information is deleted from the data memory by a central control device.
