Abstract
A robot arm device and an automated machine for unloading cargo including the robot arm device are provided. The automated machine for unloading loaded cargo from a cargo box includes a main body frame, and robot arm devices provided at opposite side portions of the main body frame. The robot arm device includes arm units provided at the opposite side portions of the main body frame to be rotatable in a multi-axis and movable forward and rearward, and a hand unit linked to the arm unit to unload the cargo in contact with the cargo.
Claims12
An automated machine for unloading cargo loaded from a cargo box, the automated machine comprising:
- a main body frame;
- and
- a pair of robot arm devices provided at opposite side portions of the main body frame,
- wherein each robot arm device includes:
- an arm unit provided at one of the opposite side portions of the main body frame to be rotatable in a multi-axis and movable forward and rearward;
- and
- a hand unit linked to the arm unit to unload the cargo,
- wherein the hand unit includes:
- an unloading conveyor belt provided at one side portion of the hand unit to sweep down the loaded cargo, as the unloading conveyor belt rotates toward the main body frame;
- a suction unit provided at an opposite side portion of the hand unit to suction and unload the loaded cargo;
- and
- a clamp unit provided at the opposite side portion of the hand unit to pick up and unload the loaded cargo,
- wherein each robot arm device determines one unloading mode of a down sweep mode, a side sweep mode, a suction mode, and a clamping mode, based on at least one of a distance to the cargo, a loaded pattern of the cargo, a loaded position of the cargo, and a type of the cargo,
- wherein each robot arm device rotates the unloading conveyor belt toward the main body frame and sweeps down the cargo, in a state that the unloading conveyor belt is placed to face the cargo above the cargo, in the down sweep mode.
