Material transportation system, transportation method and storage apparatus

A material transportation system, comprising:

• a material storage apparatus, wherein the material storage apparatus comprises a movable storage rack;
• the movable storage rack is configured to hold a plurality of material boxes, and the movable storage rack can be separated from the material storage apparatus;
• and
• an automatic transportation apparatus that can move freely along any route in any direction;
• and the automatic transportation apparatus is configured to carry and transport the movable storage rack,
• wherein the material transportation system further comprises an automatic lifting translation mechanism that is arranged underneath of the movable storage rack, a first side wall sensor and a controller;
• the first side wall sensor detects whether the automatic transportation apparatus reaches or leaves an external area of the movable storage rack, and transmits a signal to the controller if yes;
• and
• after receiving the signal of the first side wall sensor, the controller controls the automatic lifting translation mechanism to raise the movable storage rack upwardly, and controls the automatic lifting translation mechanism to extend or retract to:
• transfer a movable storage rack from the automatic lifting translation mechanism onto the automatic transportation apparatus, or to pick up a movable storage rack from the automatic transportation apparatus to be transported back into the material storage apparatus for storage.
