  • Resin pelletizer apparatus and abnormality determination method for resin pelletizer apparatus
    Patent number: 10661463
    Abstract: A resin pelletizer apparatus (100) is provided with: a die (6) that has a die surface (61) having a die hole (63) formed therein; a rotary blade (21) that cuts a resin extruded from the die hole (63) into a pellet shape in water when being rotated on the die surface (61) in the water; a sensor (150) that detects elastic waves generated by the rotary blade (21) during the rotation on the die surface (61); and a determination unit (121) that monitors the output value of the sensor (150) and determines that an abnormality has occurred when the output value of the sensor (150) is outside a predetermined range (R).
    Type: Grant
    Filed: May 16, 2017
    Date of Patent: May 26, 2020
    Assignee: Kobe Steel, Ltd.
    Inventors: Eiji Takahashi, Ryo Tabuse, Kaname Araki, Chitaka Manabe, Shin Iwasaki, Tatsuru Miyamoto

  • Resin pelletizer device and cavitation monitoring method
    Patent number: 10160153
    Abstract: Provided is a resin pelletizer device capable of monitoring cavitation. A resin pelletizer device (100) includes a die (6) including a die surface (61) in which die holes (63) are formed, rotary blades (21) that rotate on the die surface (61) in the water, thereby cutting resin extruded from the die holes (63) in the water into a pellet form, a sensor (150) that detects an elastic wave generated during the rotation of the rotary blades (21) on the die surface (61), and a determination unit (121) that monitors an output value of the sensor (150), and determines that cavitation occurs when the output value of the sensor (150) becomes less than a predetermined threshold.
