  • Patent number: 11685613
    Abstract: Diverting equipment that diverts and transports an article on a transporting route to a branching route. The diverting equipment includes: multiple transport rollers that are arranged in a branching section which is on the transporting route and which branches toward the branching route, and that are rotatable about vertical shafts; multiple diverting transport rollers that are arranged at an upstream side end of the branching route and that can rotate about vertical shafts; and a general controller that controls rotation of the transport rollers and of the diverting transport rollers. The transport rollers and the diverting transport rollers divert and transport the article from the transporting route to the branching route by rotating based on a rotational timing that the general controller controls according to a transport speed and an acceleration/deceleration state of the article that is transported toward the branching section.

  • Patent number: 11643272
    Abstract: In an article transport vehicle that is able to transport a plurality of types of articles, the efficiency of operations is improved in accordance with the type of article, while suppressing an increase in the size of the article transport vehicle. If a control device determines that an article held by a holding portion is a first-type article, the control device controls the transfer mechanism so as to cause the turning mechanism to perform a turning mechanism and cause a sliding mechanism to perform a sliding operation such that operation periods of these operations do not overlap. If the control device determines that the article held by the holding portion is a second-type article, the control device controls the transfer mechanism so as to perform the turning operation and the sliding operation such that the operation periods of these operations overlap.
