Abstract:
Provided is a highly reliable box-opening device being capable of suppressing failures of a box-opening action regardless of a size of a cardboard box sheet. The box-opening device unfolds a sheet in which first and second side surfaces and third and fourth side surfaces overlap, and forms a square-tube-shaped cardboard box. The box-opening device may have a suction disk to grasp the first side surface, a main arm having suction disks to grasp the fourth side surface and changing a posture while grasping the fourth side surface, and a control part to control a movement of the main arm so that an initial action, in which a gap is formed between the first and second side surfaces and the third and fourth side surfaces, and a main action that follows the initial action, are executed as an action of unfolding the sheet.

Claim (Index 1):
A box-opening device configured to unfold a folded cardboard box sheet in which a first side surface and a second side surface overlap with a third side surface and a fourth side surface, and form a square-tube-shaped cardboard box in which the first side surface, the second side surface, the third side surface, and the fourth side surface are arranged in this order, the box-opening device comprising:\n a first grasping part that grasps the first side surface; a first arm that has a second grasping part that grasps the fourth side surface and changes a posture while the second grasping part grasps the fourth side surface; a control part that controls a movement of the first arm so that an initial action, in which a gap is formed between the first and second side surfaces and the third and fourth side surfaces of the folded cardboard box sheet overlapping each other, and a main action, which is performed after the initial action and in which the cardboard box sheet is formed into a square tube shape, are executed as an action of unfolding the cardboard box sheet; the first arm configured to move at or slower than a predetermined speed in the initial action, and the first arm configured to move faster than the predetermined speed in the main action; and the control part configured to control the movement of the first arm based on an angle formed by the first side surface and the fourth side surface at completion of the initial action, the angle being determined according to a size of the cardboard box sheet.
