Hybrid Type Transfer Mechanism

Abstract

In a chain canveyor system, tensile force and chain slack have a significant effect on a material's vibration and transferring efficiency. Therefore it becomes an important problem for the chain conveyor to control tensile force and chain slack, Nowadays, most chain conveyor drive sprockets are driven by a motor, and the driven sprocket is controlled by a brake to give a moderate tensile force. However, it is difficult to adequately control the tensile force, because the brake has a tendency to influence the torque and revolution of the driving motor. We then developed a new driving system which has two motors ; one is the main motor for conveying materials and the other is an auxiliary motor which is used to control tensile force and chain slack without influencing torque and revolution of the main motor. In this report, we describe the performance of this system.
