The invention discloses a fully-automatic coil control method provided with a Garret coiler, and belongs to the field of automatic control of coil production lines. The method includes firstly calculating ascending starting time and a rotation speed; rotating a spiral-tube lifter to an initial position; after reaching a set number of turns of a coil, ascending the spiral-tube lifter to the highestposition, unloading the coil, and collecting the coil by the Garret coiler by utilizing a rotating drum and a lifting and ascending and descending coil disc; and finally taking the coil in the Garretcoiler out by utilizing a coil unloading machine, and automatically putting the coil on the coil unloading machine onto a tray through a coil lifter. Through control of the spiral-tube lifter ascending time and speed and Garret coiler swing speed control, fully-automatic coil control provided with the Garret coiler is achieved. Through reasonably deploying a logic motion sequence of each important device, a product coil is neater and more beautiful, and the operation efficiency of coil collection is increased.
