  • Patent number: 11939136
    Abstract: A composite liquid agent package containing a first pouch filled with a first liquid and a second pouch filled with a second liquid; and a kit for preparing a multicomponent composition, the kit including an outer bag housing the composite liquid agent package. With an opposite end section of the first pouch and an opposite end section of the second pouch being superposed, the superposed parts are heated and pressurized to exclude sealants, which are present within the opposite end sections, outwardly of the extremities of the outer layers of the opposite end sections, while heat-fusing the two extruded sealants together to join the two pouches.

  • Patent number: 9327902
    Abstract: A transfer vehicle includes a lateral pair of extendable and retractable arms, openable and closable hooks at front and rear ends of the arms, an arm opening and closing mechanism configured to change spacing between the arms, and a controller configured and programmed to control the arms and the arm opening and closing mechanism as well as the hooks. During article pickup, the controller pulls in an article onto the transfer vehicle by causing the arms to protrude to a position beyond the article in a state in which the hooks at a distal end in a pickup direction as viewed from the transfer vehicle are opened, thereafter closing the hooks to clamp the article, opening the arms after the clamping to provide a gap between the article and at least one of the arms, and retracting the arms in a state in which the hooks are closed.

  • Patent number: 8731740
    Abstract: An automatic warehouse includes multiple guided vehicles disposed at different heights along a rack and a storage shelf with a hoist in line with the rack. The storage shelf includes an intra-shelf conveyor that stores articles, and multiple shelf frames configured to vertically pass the transportation surface of the intra-shelf conveyor. The interval between the plurality of shelf frames may be varied. In parallel with the storage of articles using the intra-shelf conveyor, the shelf frames are caused to pass the transportation surface of the intra-shelf conveyor upward from below, and the articles are sequentially transferred from the intra-shelf conveyor onto the shelf frames. After the articles have been transferred to all the corresponding shelf frames, the guided vehicles store the articles on the shelf frames into the rack simultaneously.

  • Patent number: 8499920
    Abstract: In a conveyor device including a branch path, the number of articles sorted to the branch path is counted accurately. The conveyor device conveys a plurality of articles and includes a main conveyor, a first branch path, a first detector, a second detector, a detection information processing section, and a charging conveyor. The first branch path branches from the main conveyor at a first branch point. The first detector and the second detector are arranged upstream and downstream, respectively, of the branch point along a conveyance direction and are arranged to detect articles on the main conveyor. The detection information processing section is configured to calculate the number of articles sorted to the first branch path based on a difference between the number of articles detected by the first detector and the number of articles detected by the second detector.
