What are the Operation Modes of the Stacker?

November 01,2022

The stacker crane is the abbreviation of the stacking crane, which is the characteristic sign of the automated warehouse and is responsible for picking up, transporting, lifting, and transporting. Therefore, the function of the stacker directly determines the throughput efficiency of the warehouse. So how to operate the stacker?

The operation mode of the stacker


The shelf system using the stacker shall be numbered according to the position of the column, layer, and row of the shelf, to automatically enter and exit the designated position, and also facilitate the use of electronic computers to manage the goods in the warehouse. Most new large automated warehouses use electronic computers for warehouse management. However, to save equipment investment, most small automated warehouses still use manual control and semi-automatic control.


Manual control


Manual control means that the driver can check the position number on the driver's platform of the stacking crane and operate the joystick or button at the same time to complete walking, lifting, and fork in and out.


Semi-automatic control


On the driver's platform of the stacker, press the button of the required location number. The crane will automatically complete various actions of walking and lifting and stopping at the designated location number. The movement of the fork in and out is controlled by a manual lever or button. Most of the return actions are automatically returned to the original position by pressing the return key.


Fully automatic control


This is a form of unmanned operation. The control panel is mounted outside the crane and uses buttons or punch cards as commands. Therefore, as long as you press the Start key, you can remotely control the automatic inbound and outbound. Storage devices such as magnetic core memory are also used to store the inventory or varieties of each location number for inventory management.


Computer control


The ground control panel directly connected to the electronic computer shall be set to input the warehouse-in and warehouse-out instructions into the electronic computer for centralized control. The input and output commands sent by the electronic computer are stored in the front box calculator on the ground control panel. The calculator controls the stacker to automatically enter and exit the target goods, and calculates the quantity, variety, and quantity, etc. of goods, realizing the in-warehouse management.


This management method is often used in large automated warehouses. Some of the small independent shelf warehouses that have been built now use small computers for in-store management.
