Abstract

PURPOSE: To always start a belt conveyor for a predetermined period of time by sequentially short-circuiting the secondary resistors of motors of driving pulleys when the speed detection pulse value of a rotation detecting pulse generator attached to rotary pulley is smaller than the output of a linear command accelerator.
CONSTITUTION: Motors 5, 6 are provided at a first drive pulley 2, and a motor 7 is provided at a second drive pulley 3 to form a multi-drive belt conveyor. Pulse generators 8, 9, 10 are respectively attached to the motors 6, 7 and a driven pulley 4. A speed calculator 12 integrates the number of pulses of the generator 10 to calculate an accelerating speed. On the other hand, a linear command accelerator 11 outputs a linearly increasing acceleration command value with the designated starting time as a target value. A comparator 13 sequentially reduces the secondary starting resistors of the motors 4∼7 when the accelerating speed is smaller than a linear acceleration command value.
