Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a container ship used for marine transportation, which unloads and temporarily stores containers.
Conversely, the present invention relates to a container management control system used in a port cargo handling facility for loading containers on a container ship, and more particularly to a container management control system that automates container management and improves cargo handling efficiency.

[0002]

2. Description of the Related Art At present, in a port cargo handling facility that has been increasing in scale and automation, it has been necessary to reduce the number of workers and the problem of how to efficiently unload containers from a container ship and transport the containers to a storage yard. As a method of solving these problems, a method of increasing the speed at which the crane is operated, a method of automating the transportation after unloading, and the like are adopted.

[0003] In addition, containers are also computerized for receiving and dispensing containers, and an automated system for automatically transporting containers is linked to a computer to automate the process from container reception to transportation, or from transportation. Automated payments are also being made.

[0004] Even in such automated equipment, the identification of containers is generally confirmed by visual inspection. For example, even in automated equipment in which information has been advanced, a person in charge at a site where a container is unloaded is used by a staff member. Only when the input device is operated to input the ID of the container and notify the ID to the central management control network wirelessly or the like, a container transfer command to an automatic guided vehicle or the like is issued.

[0005] For this reason, if the number of staffs is limited when receiving or dispensing containers, there is a problem in unloading or loading containers, so that it is difficult to reduce the number of workers. Due to an ID reading error or an ID input error by a staff member, there is a risk that the container will be transported to a location other than the preset storage location, or that an incorrect container will be loaded.

As a technique capable of solving such a problem, there is known a "handling information management system" disclosed in JP-A-2-231399.

In this cargo handling information management system, as shown in FIG. 4, a read / write device 103 is arranged on the product discharge side of the conveyor line 102, and the read / write device 103 approaches the product discharge side of the conveyor line 102. The content of the ID card 105 attached to the forklift truck 104 is read, and when the product 106 placed on the pallet 107 comes out of the product unloading side of the conveyor line 102, the pallet 107 is read by the reading / writing device 103. The content of the ID card 108 attached to the management computer 1 is read, and the content of each ID card 105, 108 is transmitted to the management computer wireless device 110 by a wireless signal by the read / write device wireless terminal 109, and the management computer 1
11 makes the ID code of the pallet 17 and the ID code of the forklift truck 104 grasp.

Thereafter, the management computer 111 generates a transport command for the forklift truck 104, and transmits the command from the management computer wireless device 110 to the vehicle wireless terminal 112 provided on the forklift truck 104 as a wireless signal. The information is displayed on the storage and display device 113, and the operator 114 operating the forklift truck 104 transports the pallet 107 to a designated place.

Thus, the operator 114 can recognize where the product 106 conveyed to the product unloading side of the conveyor line 102 is to be transferred only by approaching the forklift truck 104 to the product unloading side of the conveyor line 102. Improving work efficiency.

[0010]

However, in such a cargo handling information management system 101, a forklift is placed at a place where a pallet 107 on which a product 106 is loaded is always conveyed, such as a product unloading side of a conveyor line 102. It is assumed that the truck 104 is kept on standby and the products 106 conveyed to the product unloading side of the conveyor line 102 are unloaded to the forklift truck 104 together with the pallets 107.

[0011] For this reason, when unloading cargo from a ship, such as in a port cargo handling facility, a gantry crane device is used to unload a container unloaded from a container ship into a wide area, and a large number of transport crane vehicles are free. In a system in which each container moves around and transports each container to a designated location in the loading yard, it is difficult to grasp the position of each transport crane vehicle.

Thus, even if the above-mentioned cargo handling information management system 101 is used in such a system, it is not possible to determine which transport crane truck is to be transported and which container has the highest efficiency. There was a problem.

The present invention has been made in view of the above circumstances, and has the following features.
In systems such as transport crane trucks, which can freely move around large areas and transport containers, containers can be automatically identified without automatically lowering cargo handling efficiency, and information on entry / exit management can be automatically recognized. Provide a container management and control system that can issue accurate transport commands to each transport crane vehicle and the like using the collected information and save labor and efficiency of cargo handling work. It is intended to be.
