ELECTRON ACCELERATOR

摘要

PURPOSE: An electron accelerator is provided to perform roll to roll supply of a roll shaft and an irradiated object in a fetching unit by forming an unwinding shaft in a feeding unit. CONSTITUTION: A fetching unit(20) comprises a motor(21) transferring torque and a roll shaft(22) rotating using the torque of the motor. The roll shaft winds an irradiated object(40) transmitted from a feeding unit(10) in a roll shape. The fetching unit is parallelly installed between the roll shafts. The fetching unit includes an idle shaft(23) rotating according to the horizontal movement of the irradiated object. A sensor(50) senses the torque of the idle shaft in real time. A controller(60) maintains reference torque by checking the real-time torque of the sensor. The controller adds and subtracts rotation speed to/from the motor.
