Abstract

PURPOSE:To improve a working property by constituting a data memory attached to a load and a rack to read and write the data at a terminal of a fork-lift truck, and to transmit and receive the contents at an interval with a control computer with a wireless installation. CONSTITUTION:When a fork 8 of a fork-lift truck 3 is inserting into a pallet, a terminal attached to the lower part of a finger bar comes nearer to a data memory of this pallet, thereby reading and writing the data automatically. Then, when a freight loaded on the pallet is inserted into a rack with the fork 8 of the fork-lift truck 3, the terminal gets closer to the data memory, reading and writing the data automatically. The reading and writing of these data are performed by a terminal machine 4 mounted on the fork-lift truck 3, and data contents are received by the wireless installation from an antenna 7 of the terminal machine 4 through a radio wave by way of a relay 5 and controlled by a control computer 1.

Description

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

[Conventional technology]

In conventional cargo handling and warehousing/shipping command systems of this type of inventory management method, personnel and warehousing data are generally read using a barcode reader.

[Problem to be solved by the invention]

However, when reading human and shipping data using a barcode reader, it is difficult to operate the barcode reader because it is far away from the driver's seat of the forklift. Additionally, forklifts often work on pallets, so if the load information for a pallet changes, the barcode needs to be replaced.

The present invention was developed in view of the above circumstances, and its purpose is to automatically read and write cargo information, such as warehousing, warehousing, product name, product number, quantity, and warehousing/retrieval location. An object of the present invention is to provide an inventory management method for a cargo handling vehicle that can improve work efficiency.

[Means and operations for solving the problem] In order to achieve the above object, the present invention provides a cargo handling and warehousing/discharging command system in which a terminal mounted on a forklift and a management computer are brought online via a wireless device. Data memory installed in loads and shelves as a means of obtaining information,
By reading or writing data using a terminal installed on the finger bar of a forklift, and transmitting and receiving the contents to and from a management computer using a wireless device, cargo information such as warehousing, warehousing, product name, product number, quantity, and input information can be obtained. Automatically read and write information such as delivery location.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

In the drawing, 1 is a management computer, 2 is a wireless device that brings the terminal 4 mounted on the forklift 3 and the management computer 1 online, 5 is a repeater, and 6 is an antenna of the repeater 5.

An antenna 7 is provided on the terminal 4 of the forklift 3, and a terminal 12 for reading information on the load 10 and the shelf 11 is provided below the finger bar 9 to which the fork 8 of the forklift 3 is attached.

On the front of the pallet 13 on which the load 10 is loaded, there is a data memory 1 for each load 1, which contains data such as product name, product number, and number of items.
4 is a provision.

Furthermore, a data memory 15 for the shelf 11 containing shelf address data is provided on the front surface of the shelf 11.

Further, the terminal device 4 is composed of a display, an operation panel, and the like. The data in the data memories 14 and 15 can be read from a distance of several tens of meters from the terminal 12 via radio waves without contact.

Next, the operation will be explained.

When the fork 8 of the forklift 3 is inserted into the pallet 13, the terminal 12 approaches the data memory 14 and automatically reads and writes data.

When the load 10 loaded with the pallet 13 is inserted into the shelf 11 using the forklift 3, the terminal 12
approaches the data memory 15, and data is automatically read and written.

Reading and writing of these data is performed by the terminal device 4.

Then, the data contents are received by the wireless device 2 via the repeater 5 by radio waves from the antenna 7 of the terminal 4, and are managed by the management computer 1.

〔Effect of the invention〕

As described in detail above, the inventory management method for a cargo handling vehicle according to the present invention is a means for obtaining information on cargo in a cargo handling/warehousing/discharging command system in which a terminal mounted on a forklift and a management computer are brought online via a wireless device. A terminal installed on the finger bar of a forklift reads or writes data from a data memory attached to a load or shelf, and the contents are sent and received to and from a management computer using a wireless device. It is something to do.

Therefore, cargo information such as warehousing, warehousing, product name, product number, etc.
It is possible to automatically read and write information such as quantities and storage/output locations, improving work efficiency.
