Abstract: An unloading device includes a pair of support bodies which supports side surfaces of a vulcanized tire vulcanized by a tire vulcanizer from the lower portion in a vertical direction, and a movement portion which moves the support bodies. The movement portion includes a horizontal movement mechanism which moves the support bodies in a horizontal direction from a position at which the vulcanized tire can be extracted from the tire vulcanizer to a position at which the vulcanized tire can be held by a PCI device for cooling the vulcanized tire, and a transport mechanism which transports the vulcanized tire, which is received from the PCI device by the support bodies, to a carrying-out destination.

Abstract: Provided is a pressure vessel having a weld portion structure of a plate material in which a plate receiving a pressure or a load is attached by welding to a wall surface member such as a shell or a head. In the pressure vessel, a stress concentration on the weld portion structure is alleviated and an increase in welding amount and plate thickness of the wall surface member are suppressed. The pressure vessel includes a weld structure portion in which an end of a bolster plate (22) attached so as to partition an inside of a container body and receiving a pressure or a load is attached by welding to a wall surface member (30) of the container body, the weld structure portion having at least two sections including a weld portion (40), i.e., shape displacement points of the weld portion (40) and a stepped portion (50).

Abstract: A dust seal structure of an internal mixer including a casing having a mixing chamber defined therein, and a rotor rotating in the mixing chamber for kneading a material, which is charged into the mixing chamber to be kneaded there, comprises a ring-shaped cylinder fitted to a rotor shaft of the rotor and mounted on a peripheral edge of an opening portion of the casing through which the rotor shaft passes, the cylinder being located at the peripheral edge of the opening portion of the casing, and being adapted to urge a ring-shaped sealing member fitted on the rotor shaft in a direction of the rotor shaft to inhibit leakage of the kneading material from the mixing chamber.

Abstract: The present invention provides a tire vulcanizing system of a type such that a mold assembly in which tire vulcanization is being carried out is transported to a mold opening/closing station, which is equipped with a central mechanism for operating a bladder, the central mechanism being configured so that a plurality of claws are provided which attach and detach a post cylinder of a central mechanism driving section incorporated in the mold opening/closing station to and from a center post of a central mechanism operating section incorporated in the mold assembly, a sensor for detecting the decrease in pitch circle diameter of the claws is provided, expanding/contracting means for the claws is incorporated in the central mechanism driving section, and the sensor is assembled to the expanding/contracting means.
