Abstract: In a box assembly device, a holding mechanism causes one of bottom boards to contact a first jig and folds the bottom board inside, while the holding mechanism holding the box material in a state where the box material is developed in a cylindrical shape from a folded state. The folding mechanism folds the bottom flap inside so as to overlap with one of the bottom boards. The holding mechanism causes the other bottom board to contact the second jig while holding the box material and folds the other bottom board inside and upwardly so as to overlap with the bottom flap to engage the bottom boards with each other.

Abstract: A box unpacking device includes a robot, and a cutting device. A robot hand is attached to a wrist of the robot. The robot hand has a holding device configured to hold a packed box. The cutting device has a cutting blade of which the point is oriented downward or obliquely downward. The robot can move the box held by the holding device in a vertical plane, and change an angle of the box in the vertical plane.

Abstract: An end effector is to be attached to a tip-end part of a robotic arm and unpacks a cardboard box of which one or more flaps provided to one end of a side wall are fixed mutually or to the side wall to constitute one of end walls. The end effector includes a body part to be attached to the tip-end part of the robotic arm, a box holding part provided to the body part and configured to hold the cardboard box by holding a part of the cardboard box other than the one end wall, and a punching part provided to the body part and configured to form a through-hole in a wall of the cardboard box other than the one end wall.

Abstract: A particulate matter supply device having a simple configuration, which includes: a fixing plate through which a flow path that allows passage of particulate matter penetrates; a bottom portion through which a discharge port that allows passage of particulate matter penetrates; and a movable portion between the fixing plate and the bottom portion, has an accommodation region capable of accommodating particulate matter in the accommodation region and penetrating the movable portion along a facing direction in which the fixing plate and the bottom portion face each other, and is movable to a position where the accommodation region communicates with the flow path and to a position where the accommodation region communicates with the discharge port. The fixing plate is provided with a level-off portion that, when the movable portion moves, levels off particulate matter so as to remove an amount of particulate matter exceeding a capacity of the accommodation region.

Abstract: A particulate matter supply device capable of suppressing leakage of particulate matter includes an accommodation region formed so as to penetrate a rotating member along a facing direction in which a spiral member and a fixing plate face each other. The spiral member includes a level-off portion that levels off particulate matter in excess of the capacity of the accommodation region when the rotating member moves from a position where the accommodation region communicates with a flow path for supplying particulate matter to the accommodation region to a position where the accommodation region communicates with a discharge port.

Abstract: A food holding apparatus is a food holding apparatus configured to hold or release an ingredient. The food holding apparatus includes a base portion, a pair of arms drivably attached to the base portion, a pair of distal end portions respectively provided to distal ends of the pair of arms, and a control device configured to control an operation of the pair of arms. The control device is configured to control the operation of the pair of arms such that the pair of distal end portions hold the ingredient in an inner side between the distal end portions in a state of facing each other, and the pair of distal end portions release the ingredient held in the inner side between the distal end portions in a state of being separated from each other.
