Abstract: A rice husker includes a pair of husking rolls. One of the pair of husking rolls is attached to a main shaft and the other of the pair of husking rolls is attached to an auxiliary shaft movable to be close to and away from the main shaft. The rice husker includes abnormality determination means. The abnormality determination means determines that the husking rolls fail to work normally when vibrations having a preset intensity larger than the preset intensity are successively detected by a vibration sensor until a certain time elapses. The certain time is from the start of a husking action to disappearance of distortion on a surface of the husking roll. The vibration sensor is provided on at least either of bearing units of the main shaft and the auxiliary shaft. The vibration sensor detects vibrations occurring due to the husking action by the pair of husking rolls.

Abstract: An operation monitoring system for a sifting device includes: movement state sensing means to be provided for a sieve frame of the sifting device that rotationally oscillates, and capable of sensing a movement state of the sieve frame; and operation monitoring means capable of monitoring an operation state of the sifting device based on measured data transmitted from the movement state sensing means. The operation monitoring means includes a measured data arithmetic processing unit that subjects the measured data to arithmetic processing, and a movement state display unit capable of displaying the movement state of the sieve frame based on arithmetic processing data obtained by the measured data arithmetic processing unit.

Abstract: A sieving device includes a mount, and a vibration unit configured to perform reciprocating vibration relative to the mount in one direction in plan view and including a sieve frame. The vibration unit includes a first sensor unit and a vibration state measurement unit. The first sensor unit includes a vibration-unit acceleration sensing unit capable of sensing acceleration of the vibration unit, and a vibration-unit angular velocity sensing unit capable of sensing angular velocity of the vibration unit. The vibration state measurement unit measures a vibration state of the vibration unit based on the acceleration and the angular velocity of the vibration unit, which are sensed by the first sensor unit.

Abstract: The present invention is directed to managing a process in a factory while employing a communication method suitable to various kinds of data that should be transmitted. A wireless communication apparatus configured to manage a process in a factory includes an interface connected to a device and usable to receive data from the device, a first wireless communication portion, a second wireless communication portion, and a controller configured to, to wirelessly transmit the data received via the interface, select one of the first wireless communication portion and the second wireless communication portion according to this data. The first wireless communication portion is configured to carry out communication at a higher speed and with a larger capacity than the second wireless communication portion. The second wireless communication portion is configured to carry out more reliable communication than the first wireless communication portion.

Abstract: A method and an apparatus for controlling a milling roll machine capable of accurately monitoring a surface temperature of a roll and preventing a high temperature abnormality occurring on a roll surface from being overlooked are provided A temperature sensor S that monitors surface temperatures of a pair of rolls 4 and 5 and a temperature of a milled product after passing through the rolls is provided in the vicinity of the pair of rolls 4 and 5, and opening/closing control of the gap between the rolls 4 and 5 or flow rate control of the raw material stock is performed according to the surface temperatures of the rolls and the temperature of the milled product after passing through the rolls detected by the temperature sensor S.
