How to operate high stacking system {METHOD FOR OPERATING HIGH STACKING SYSTEM}

The present invention relates to a method for operating a high stacking system, and more particularly, in the logistics field of a container terminal, a work scheduling and assignment method for equipment operation, a container device positioning method, a truck work positioning method, and a preliminary work. The present invention relates to a method of operating a high stacking system capable of optimally operating a method of performance.

In the conventional container terminal, the container has been loaded on the floor in about 5 stages, but the high stacking system loads the container using a high-rise structure of about 20 floors, thereby increasing land utilization by more than four times, and reducing operation manpower. The automation of tasks allows the operation of safe container terminals.

For example, when the high stacking system is described with reference to FIG. 1, the entire building on which the container is installed is named as a device building, and the device building is named as a block for loading the containers of two to three rows of left and right containers based on a bogie lane. In the vertical direction of the block, the container is loaded in the longitudinal direction, in which one longitudinal section of the container is called a unit, and the unit is capable of loading a 20 'container and a structure capable of loading a 40' container. It consists of.

In addition, the container is loaded in the width direction in the horizontal direction of the block. In this case, the width of one container in the width direction is referred to as a row, and each unit can be stacked in layers. In this case, one layer is called a tier. do.

In addition, the space where one container is loaded is called a cell. In one device building, there are one or more loaders on the land side and the sea side that are equipped with a container for loading and unloading the container from the truck, and a vehicle for transporting the container loaded and unloaded from the loader to the position of the elevator. One to two blocks are installed per block.

In addition, each unit of the block is provided with a device called a lifter for transporting the container to the position of the target tier, and a device called a traveler for transporting the container from the tier to the corresponding cell is included in the lifter. In addition, the space that the truck can enter and unload from the loader is called TP (Transfer Point), and this TP is divided into compartments on the land side and the sea side, respectively.

However, the container loading method using the high-rise structure as described above can be equipped with a large number of containers per unit area, but the optimal operating method is necessary because the handling time per container unit increases.

That is, the present invention is to solve the above problems, the purpose is to lower the container located on the high floor downstairs before starting the operation in the container terminal, or to move the container to the other place to interfere with the container to handle It is to provide a method of operating a high stacking system that can optimally operate preliminary work, determine the optimal device location, assign the equipment to the workload, and plan the optimal work schedule.
