Title: Control method of belt conveyor device and belt conveyor facility
Inventor: FUKUNAGA TOMOYUKI
IPC: B65G43/00
Filed: 2011-11-30
Abstract: PROBLEM TO BE SOLVED: To reduce a maintenance cost by extending the service life of a replacement part such as a roller and to attain energy saving in a belt conveyor device.SOLUTION: In the belt conveyor device conveying a bulk load as a conveyance object, the quantity of the conveyance object per unit length on a running belt is set as a predetermined amount of load. Even if the quantity of the conveyance object loaded on the belt during an operation of the belt conveyor device changes, the speed of the belt is adjusted in response to a changed amount of the conveyance object and the conveyance object loaded on the belt is controlled so as to meet the predetermined amount of load. Because a required operation is performed at a necessary minimum belt speed according to the quantity of the conveyance object, the energy of belt driving power and the like can be decreased. In addition, because the number of rotations per conveyance amount can be suppressed with respect to the total number of rotations of the bearing currently used for the belt conveyor, the service life of each replacement part such as a roller can be extended.
