  • Patent number: 9758310
    Abstract: A controller provided to an article transport device is configured to perform a transfer control and an oscillation damping control. The transfer control is a control for controlling an operation of an actuator while a travel portion is at rest to cause a first support portion to be moved with respect to the travel portion between a first position within a travel path and a second position for transferring an article between the first support portion and a transport target location which is one of a transport origin and a transport destination for the article. The oscillation damping control is a control for controlling the operation of the actuator based on a physical quantity detected by a detector, while the travel portion is traveling and the first support portion is supporting an article, to reduce the oscillation of the article supported by the first support portion that occurs while the travel portion is traveling.

  • Publication number: 20170197794
    Abstract: An operation device is provided with: a coupler portion configured to be coupled to a travel member that travels within a travel space that is located above a passage space that allows an operator to pass through; and a rod-shaped portion that extends from the coupler portion to the passage space. The travel member is provided with: a brake mechanism; a coupling-target portion to which the coupler portion is coupled; and a cancellation input terminal. The operation device is provided with: a cancellation output terminal configured to be connected to the cancellation input terminal; a command receiver configured to receive a manual operation that is performed to make an instruction to output the cancellation signal; and a grip configured to be gripped by the operator. The grip and the command receiver are located within the passage space when the coupler portion is coupled to the coupling-target portion.

  • Patent number: 4826907
    Abstract: An acrylic or methacrylic resin emulsion coating composition comprising a blended mixture composed of(1) 100 parts by weight as solid resin content of a copolymer resin emulsion [A], the copolymer resin therein having a glass transition temperature Tg(A), determined by the DSC method, of about -10.degree. to about -55.degree. C., and said copolymer resin emulsion [A] being an aqueous emulsion-copolymerization product being free from a copolymerizable diallyl component and derived from acrylic and/or methacrylic monomers (a) and (b) specified in the claims in the presence of a polyoxyethylene/polyoxypropylene block copolymer,(2) 20 to 300 parts by weight as solid resin content of a copolymer emulsion [B], the copolymer resin therein having a glass transition temperature Tg(B), determined by the DSC method, of less than 0.degree. C., and satisfying the following equationTg(B)-Tg(A)=10.about.55.degree. C.
