in the initial state, the detachable stacking rack 2 filled with blanks is parked in the rack guide device near the master control cabinet, and the AGV skip is parked at the initial material taking position, namely under the rack. And the master control system 4 dispatches orders to the industrial robot, the AGV skip car and the machining center.

Backpack AGV skip starts jacking cylinder, will unstack work or material rest 2 jack-up and fix on AGV skip through the bolt on the jacking board, makes the work or material rest bottom leave ground simultaneously. The AGV skip moves along the magnetic strip 21 on the ground according to a planned moving path.
