Tubular body cutting device and tubular body cutting method

Abstract

A tubular body cutting device configured to cut a tubular body includes: a conveyor configured to convey the tubular body that is continuous, along an axial direction of the tubular body; a measurement unit configured to measure a diameter size of the tubular body and a conveyance speed of the tubular body; and a cutting controller configured to control a laser irradiation unit provided at a radial direction outer side of the tubular body and at a prescribed position in a circumferential direction of the tubular body while being separated from the tubular body. The cutting controller is configured to control an irradiation direction and an irradiation timing of a laser light beam from the laser irradiation unit to the tubular body based on the diameter size and the conveyance speed measured by the measurement unit or held as data calculated in advance.
