  • Patent number: 10618017
    Abstract: A method of mixing a rubber composition includes a carbon introduction step and a uniform dispersion step. In the carbon introduction step, on the basis of a deviation between a rate of temperature increase of the rubber mixture (R) and a target value, at least one of a ram pressure (Pr) and a rotational speed (N) of the mixing rotor (2) is PID controlled so that the ultimate temperature of the rubber mixture (R) at the conclusion of the step is within a tolerance range. In the uniform dispersion step, the ram pressure (Pr) or the rotational speed (N) of the mixing rotor (2) is adjusted to reduce a deviation between a value based on successively detected data associated with a predetermined control target and a target value.

    Abstract: A device for measuring the state of contact of a measuring roller of a conveyor belt includes a pressure sensor provided on a rotating surface of the measuring roller, which rotates in contact with an inner peripheral surface of a conveyor belt stretched between pulleys. The pressure sensor detects resistance force acting when the conveyor belt rides over the measuring roller. A rotational position sensor detects the circumferential position, on the rotating surface, of the pressure sensor. The data detected are sequentially wirelessly transmitted to the outside of the measuring roller by a transmission unit installed on the measuring roller, and the transmitted detection data are received by a receiver.
