Abstract

A direct drive conveyor belt comprises an endless toothed thermoplastic belt and multiple driving pulleys working in tandem. The pulleys have driving sheaves and non-driving sheaves and the belt teeth are adapted to engage the driving sheaves as the belt wraps around the pulleys. The pulleys are driven by a common drive shaft through continuous duty clutches and are out of phase with each other such that the belt teeth are alternately engaged by driving sheaves on different pulleys. The pulleys can also be independently driven. The endless belt can alternately be driven by a computer controlled motor with an external rotor with sheaves where the speed of the motor is accelerated between successive engagements of a belt tooth.
