  • Patent number: 11780194
    Abstract: A supply apparatus that supplies corrugated cardboard sheets to a supply position in a box-making section that opens folded corrugated cardboard sheets and makes boxes. The supply apparatus comprises a conveying unit, a drive unit, and a control unit. The conveying unit conveys a plurality of the corrugated cardboard sheets to the supply position with the corrugated cardboard sheets stacked. The drive unit drives the conveying unit. A controller, serving as the control unit, estimates the total quantity of the plurality of stacked corrugated cardboard sheets on a conveying surface of the conveying unit. The controller acquires a value pertaining to the drive force of the drive unit when the drive unit drives the conveying unit, and estimates the total quantity of the plurality of stacked corrugated cardboard sheets on the basis of the acquired value.

  • Patent number: 11396393
    Abstract: A box packing device includes a push-in mechanism, a retention mechanism, a guide, and a control unit. The push-in mechanism pushes, into a box that is in a state in which an opening thereof faces sideways, the article through the opening. The retention mechanism retains the box that is in a state in which the opening faces sideways and lowers the box after the article have been pushed into the box by the push-in mechanism. The guide opposes the opening and is configured to prevent the article from falling out from the opening of the box that has been lowered by the retention mechanism. The control unit temporarily increases the distance between the box and the guide after the article have been pushed into the box by the push-in mechanism.

  • Publication number: 20210101354
    Abstract: A cardboard box assembly device, that folds four flaps provided at edges of an opening in a cardboard box to surround the opening, is disclosed. The cardboard box assembly device includes a folding unit, a pushing unit, and a drive unit. The folding unit folds each of the four flaps in a prescribed sequence and closes the opening. The pushing unit pushes one of the four flaps, that is folded last, inward into the cardboard box as a locking flap, and overlaps the locking flap onto the other flaps. The drive unit contacts the cardboard box and imparts a prescribed displacement to the cardboard box. Parts that engage with one another are formed between the locking flap and at least one of the other flaps. The drive unit moves the locking flap relative to the other flaps due to the displacement when the pushing unit pushes the locking flap.

  • Patent number: 10875674
    Abstract: A push-in mechanism pushes articles into a box that is opened sideways. The push-in mechanism is provided with a box standby part, an article placement part, a push-in plate, a horizontal movement mechanism, and a lifting/lowering mechanism. The box standby part causes the boxes to wait. The article placement part has a placement surface on which the articles are temporarily placed. The push-in plate is installed in a standing state so as to have a pressing surface for pressing the articles toward the box. The horizontal movement mechanism causes the push-in plate to reciprocate horizontally above the placement surface so that the push-in plate moves toward the box or moves away from the box. The lifting/lowering mechanism moves the push-in plate so as to change a separation distance in the height direction between a lower edge of the pressing surface and the placement surface.

  • Publication number: 20200002039
    Abstract: The present invention provides an article alignment device that can inhibit posture disorderliness when articles land on a conveyor belt. The posture of bags when the bags transfer from an input conveyor to a first aligning conveyor is inclined in such a way that the portions of the bags that land on bags already placed on the first aligning conveyor are higher and the portions of the bags that land directly on the first aligning conveyor are lower, so the bags land on the first aligning conveyor before or at the same time that they contact the bags that were placed on the first aligning conveyor before them. Additionally, the frictional force between the first aligning conveyor and the bags is greater than the frictional force between the bags, so sliding between the bags is prevented, as is posture disorderliness.

  • Patent number: 10472108
    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.

  • Patent number: 9862509
    Abstract: A boxing apparatus erects packages that can be erected along a limited section of a conveyor, without having to erect them all at once, even with individual packages that are long in the feed direction. The boxing apparatus has a fourth conveyor belt that blocks the front of a line of incoming packages and exerts an upward force on the front package. The front package is raised up by this upward force, so the following package rides up onto the package in front, and the packages are erected successively. Consequently, even individual packages that are long in the feed direction can be erected at a limited section of a third conveyor belt.
