Algorithm of conveyor stopping with preliminary braking of tail pulley

The algorithm of belt conveyor stopping with preliminary braking of its tail pulley is proposed and described. The method of calculating an optimal value of the braking torque for the belt stopping without slip is determined. The algorithm efficiency is proved by modeling in Matlab. The model includes an asynchronous motor, a belt conveyor and an adjustable take-up. The model has computing units for finding current values of drag factor, belt tensions and resistance to motion. The main results of this study are the method of calculating the brake torque for the conveyor tail pulley, and the transient processes of change in the belt stresses and drag factor. For proving applicability of the proposed algorithm, the belt strength calculation was carried out, and the starting burdens of the motor were tested. The proposed algorithm allows elimination or minimization of the belt slip on the driving drum during its stopping. For another thing, the use of the algorithm in combination with braking of the drive makes it possible to reduce greatly the time of the drive stopping when the belt slip may take place. This will diminish the belt wear and the conveyed cargo loss, and, consequently, will enhance the conveyor efficiency even in case of incomplete elimination of the belt slip.
