  • Patent number: 10934033
    Abstract: A bag-making and packaging apparatus creates one product per cycle by packaging articles in a bag made from a film. The bag-making and packaging apparatus includes a longitudinal sealing mechanism, a guide, an article sensor, a transverse sealing mechanism, a cutting mechanism, and a prediction unit. The guide guides the articles which fall from above into a film tube. The transverse sealing mechanism forms a transversely sealed part in the film tube with each cycle. The cutting mechanism cuts the film tube in the transversely sealed part with each cycle. The prediction unit predicts whether or not jamming of the articles could occur in the transverse sealing mechanism on the basis of an output of the article sensor with each cycle. When the prediction unit has predicted that the jamming could occur in a certain cycle, the cutting mechanism does not cut the film tube in the certain cycle.

  • 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: 20200394634
    Abstract: [Object] To provide an article discrimination system that can accurately infer the type of an article from an article image. [Solution] An article discrimination system includes an imager, an inference component, and a setting component. The imager captures an image of an article to acquire an article image. The inference component acquires first information which the inference component utilizes to infer the type of the article from the article image and, based on the first information acquired, infers one or plural types for the type of the article from among an article type group. The setting component sets at least one of types of articles that are available and types of articles that are not available among the article type group. The inference component preferentially infers, as the type of the article corresponding to the article image, the types of articles that are available over the types of articles that are not available.
