Operation of stacker crane

The shelf system using stacker crane should be numbered according to the cargo position of the column, layer and row of the shelf, so as to realize automatic entry and exit to the designated cargo position, and also facilitate the use of electronic computers for inventory management. In fact, most of the latest large-scale stereoscopic automatic warehouses use electronic computers for inventory management. However, in order to save equipment investment, most small automatic warehouses still use manual control and semi-automatic control.
1. Manual control
Manual control is that the driver checks the cargo position number on the driver's desk of the stacker crane while operating the joystick or button to complete walking, lifting, and fork entry and exit.
2. Semi-automatic control
The driver presses the button of the required cargo position number on the driver's desk of the stacker crane, and the crane automatically completes various actions of walking, lifting, and stopping at the designated cargo position number. The entry and exit action of the fork is controlled by a manual joystick or a button. The return action is mostly to press the return button to automatically return to the original position.
3. Fully automatic control
This is an unmanned form. The control panel is installed outside the crane, and buttons or punch cards are used as instructions. Therefore, as long as the start button is pressed, the stacking crane can be remotely controlled to automatically enter and exit the warehouse. Recently, there are also storage devices such as magnetic core storage to store the inventory or variety of each cargo location number for warehouse management.
4. Computer control
Set up a ground control panel directly connected to the electronic computer, input the warehouse entry and exit instructions into the electronic computer for centralized control. The warehouse entry and exit instructions issued by the electronic computer are stored in the front box calculator on the ground control panel. The calculator controls the stacking crane to automatically enter and exit the target goods, while performing calculations such as the warehouse entry and exit cargo location number, variety, and frequency, and implements warehouse management.
This management method is often used in large-scale three-dimensional automatic warehouses. In the small independent shelf-type warehouses that have been built, some small electronic computers are also used for warehouse management.
