This is the principle of our company's high-speed plate warehouse, which uses a forklift to transport the stacked plates to the roller line at the stacking position, and the stacking roller line transports the stacked plates. The board is transported to the designated position of the board warehouse machine, and the fork action of the board warehouse machine lifts the top stack of the lowest stack of stacked boards. At this time, the stacking conveyor rolls. The tube line action sends away the bottom stack board, and the fork rod action of the board warehouse machine lowers the lifted stack board to the conveyor roller line, and so on in a cycle.
