Discharging control system and discharging control method

Abstract

The invention provides a discharging control system. The discharging control system comprises a detecting unit, a calculating unit and a control unit, wherein the detecting unit is used for determining incompletely-discharged stock bin in stock bins, the calculating unit is used for calculating the discharging interval time Y of the matched stock bins with adjacent discharging orders according to the discharging order, the positions W of the stock bins, the speed V of a conveying belt, the lengths L of discharging doors and the distance D between the adjacent discharging doors, the position Wn of the nth stock bin is equal to n which is progressively increased along the motion direction of the conveying belt, wherein Yj=(Wi-Wj+1)*X+(Wi-Wj)*J, X=L/V, J=D/V, the discharging orders of the ith stock bin and the jth stock bin are adjacent, and the ith stock bin is used for discharging after the jth stock bin is used for discharging. When the jth stock bin is used for discharging, the control unit can control the opening of the discharging doors of the ith stock bin after waiting for the waiting time Yj. The invention also provides a discharging control method. According to the technical scheme of the discharging control system, different aggregates can be prevented from being piled on the conveying belt in the discharging process so as to avoid the scattering of the aggregates. Moreover, the discharging time can be shortened, and the discharging efficiency and the aggregate mixing effect are enhanced.

Description

technical field [0001] The invention relates to the technical field of mixing plants, in particular, to a discharge control system and a discharge control method. Background technique [0002] Concrete mixing plant aggregates are divided into different specifications, according to which aggregates are loaded into different silos, and each production task formula may use several kinds of aggregates. [0003] In the prior art, when the mixing station is in production, the unloading sequence C of the aggregate and the unloading interval Y between the batching bins containing different aggregates are preset in the host computer system n , when unloading each aggregate start unloading time point is K n , the time taken to complete the unloading process is T n . The control system opens the corresponding batching bin according to the formula control of the production task, and the batching bin with the unloading sequence C=1 is at time K 1 start to unload the aggregate; the el...

Problems solved by technology

[0004] Using this unloading method to unload the aggregates onto the conveyor belt will form n piles of aggregates, and the conveyor belt will bring the aggregates into the storage equipment under the drive of the motor. Since the aggregates are unloaded in order, the aggregates in the storage equipment The formation of n types of aggregate stratification in the middle, the mixing effect is poor when stirring

And since the T of each ingredient bin n different when T n >Y n When T n n When the n piles of aggregates on the conveyor belt are discontinuous, the unloading time is increased and the efficiency is low
