In the site surrounding the warehouse, production workshop and packaging workshop, there are conveyor chains composed of many belt conveyors, roller conveyors, etc., which are connected to form a continuous conveyor line. The entrance and exit of the material are provided with a path fork device, a lift and a ground conveying line.

In this way, a closed circulating conveyor line system can be formed in the warehouse, production workshop and packaging workshop. All materials used in the production process, such as materials, parts, components and finished products, must be installed in the tray boxes with barcode before entering the conveyor line system.

Under the action of the production order issued by the production management system, the pallet box containing materials enters the conveyor line system from the designated entrance.
