  • 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.
