  • Patent number: 11787643
    Abstract: Diverting equipment for conveying an article on a conveyance path to a branching path formed so as to branch from the conveyance path. In the conveyance path, a branching section to the branching path has a plurality of conveyance rollers disposed in a conveyance direction H of the article in the conveyance path and a direction orthogonal to the conveyance direction H of the article in the conveyance path, the conveyance rollers forming the conveyance surface of the conveyance path and being rotatable around the axes of vertical shafts. Between the adjacent conveyance rollers disposed in the direction orthogonal to the conveyance direction H of the article, a gap is formed along the conveyance direction H of the article. In the gap, a rail capable of supporting the article is extended along the conveyance direction H of the article.

  • Patent number: 11691181
    Abstract: An article sorting apparatus includes an article support body, article lateral pushing bodies, a rectilinear-movement guide body, a sliding guide body having a sliding guide surface, and a diverting mechanism. The sliding guide surface is disposed so as to be spaced apart from the diverting mechanism in a main transport direction across a separation region, and the separation region is provided so as to include a contact start region that is a region in the main transport direction where each of the article lateral pushing bodies initially comes into contact with a target article.

  • 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: 8597456
    Abstract: A method for producing an organic EL device includes the steps of: preparing an adhesive sheet on which a resin substrate is laminated, allowing the resin substrate to adhere onto a hard substrate with the adhesive sheet interposed therebetween, forming an organic EL element on the resin substrate, thereby producing an organic EL device including the resin substrate and the organic EL element, and peeling the organic EL device from the hard substrate. The adhesive sheet includes a first adhesive layer for being bonded to the hard substrate, and a second adhesive layer formed on the first adhesive layer and bonded to the resin substrate. A non-adhesive region is defined at an end portion of the resin substrate, the non-adhesive region not overlapping with the second adhesive layer but overlapping with the first adhesive layer when projected in the thickness direction.
