Control device for a rotating cylinder using multiple beveled wheels

A control device for a rotating cylinder comprising:

• a first rotary unit including a first wheel and a second wheel, of which inclined surfaces having a deflection angle based on each of base surfaces are disposed to contact each other;
• a second rotary unit connected to the first rotary unit and including a third wheel and a fourth wheel, of which inclined surfaces having a deflection angle based on each of base surfaces are disposed to contact each other;
• and a third rotary unit including a fifth wheel and a sixth wheel, of which inclined surfaces having a deflection angle based on each of base surfaces are disposed to contact each other, wherein the first to sixth wheels are disposed in sequence in one direction;
• a driving unit independently driving the first to sixth wheels;
• a memory storing a command performing an operation;
• and
• a processor connected to the memory and the driving unit to execute the command,
• wherein the operation rotates at least one wheel among the first to sixth wheels to control the driving unit such that an inclination angle of the rotating cylinder, an inclination angle of the base surface of the sixth wheel with respect to the base surface of the first wheel, or a position of the base surface of the sixth wheel with respect to the base surface of the first wheel is adjusted to a preset target value.
